FORWARD In March 2001, the National Institutes of Health issued the following warning: "The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading."1 Furthermore, because of the rapid increase in Internet-based information, many hours can be wasted searching, selecting, and printing. Since only the smallest fraction of information dealing with sleep deprivation is indexed in search engines, such as www.google.com or others, a non-systematic approach to Internet research can be not only time consuming, but also incomplete. This book was created for medical professionals, students, and members of the general public who want to know as much as possible about sleep deprivation, using the most advanced research tools available and spending the least amount of time doing so. In addition to offering a structured and comprehensive bibliography, the pages that follow will tell you where and how to find reliable information covering virtually all topics related to sleep deprivation, from the essentials to the most advanced areas of research. Public, academic, government, and peer-reviewed research studies are emphasized. Various abstracts are reproduced to give you some of the latest official information available to date on sleep deprivation. Abundant guidance is given on how to obtain free-of-charge primary research results via the Internet. While this book focuses on the field of medicine, when some sources provide access to non-medical information relating to sleep deprivation, these are noted in the text. E-book and electronic versions of this book are fully interactive with each of the Internet sites mentioned (clicking on a hyperlink automatically opens your browser to the site indicated). If you are using the hard copy version of this book, you can access a cited Web site by typing the provided Web address directly into your Internet browser. You may find it useful to refer to synonyms or related terms when accessing these Internet databases. NOTE: At the time of publication, the Web addresses were functional. However, some links may fail due to URL address changes, which is a common occurrence on the Internet. For readers unfamiliar with the Internet, detailed instructions are offered on how to access electronic resources. For readers unfamiliar with medical terminology, a comprehensive glossary is provided. For readers without access to Internet resources, a directory of medical libraries, that have or can locate references cited here, is given. We hope these resources will prove useful to the widest possible audience seeking information on sleep deprivation. The Editors

CHAPTER 1. STUDIES ON SLEEP DEPRIVATION Overview In this chapter, we will show you how to locate peer-reviewed references and studies on sleep deprivation.
The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and sleep deprivation, you will need to use the advanced search options. First, go to http://chid.nih.gov/index.html. From there, select the “Detailed Search” option (or go directly to that page with the following hyperlink: http://chid.nih.gov/detail/detail.html). The trick in extracting studies is found in the drop boxes at the bottom of the search page where “You may refine your search by.” Select the dates and language you prefer, and the format option “Journal Article.” At the top of the search form, select the number of records you would like to see (we recommend 100) and check the box to display “whole records.” We recommend that you type “sleep deprivation” (or synonyms) into the “For these words:” box. Consider using the option “anywhere in record” to make your search as broad as possible. If you want to limit the search to only a particular field, such as the title of the journal, then select this option in the “Search in these fields” drop box. The following is what you can expect from this type of search: •
Sleep Disorders: Overview and Relationship to Orofacial Pain Source: Dental Clinics of North America. 41(2): 189-209. April 1997. Summary: In this article, the author considers sleep disorders and their relationship to orofacial pain. The author notes that when pain is present, sleep becomes disrupted. Consequently, the days are seemingly longer and normal activities are more difficult because of inadequate rest. The author briefly reviews the history of sleep disorders, normal sleep, the impact of temperature on sleep, sleep deprivation, and the potential impact of drug ingestion. The author then introduces sleep disorders in general (including their classification) and discusses specific sleep disorders related to orofacial pain: sleep apnea, insomnia, primary snoring (upper airway resistance syndrome), periodic limb movement disorders, and sleep bruxism (grinding the teeth). Other sleep

related disorders that occur less frequently but may contribute to an orofacial pain problem are also discussed, including posttraumatic hypersomnia, sleep related asthma, sleep related gastroesophageal reflux, shift work sleep disorders, irregular sleep wake pattern, and sleep deprivation in Lyme disease. The article concludes with brief sections on related painful conditions and sleep, including burning mouth syndrome, rheumatoid arthritis, menopause, trigeminal neuralgia, glossopharyngeal neuralgia, Lyme disease, headache disorders, temperal arteritis (headache), temporomandibular disorders, and atypical odontalgia. 5 figures. 2 tables. 35 references. •
Self-Care Regimens for Patients With Interstitial Cystitis Source: Urologic Clinics of North America. 21(1): 121-130. February 1994. Contact: Available from W.B. Saunders Company. The Curtis Center, Independence Square West, Philadelphia, PA 19106. (800) 654-2452. Summary: In this article, the author explores self-care regimens for patients with interstitial cystitis (IC). The author notes that coping with interstitial cystitis requires dealing with chronic pain and sleep deprivation, acceptance of a difficult diagnostic process, and patience during a trial-and-error regimen to find the combination of therapeutic modalities that can achieve a remission in symptoms. Topics covered include the systemic manifestations of IC; gynecologic manifestations of IC; the typical flare and remission course of IC; etiology; diagnostic work-up; recommended approach to patient management; and self-care treatment regimens, including dietary manipulation, nutritional supplements, stress reduction, exercise, bladder retraining, and bladder instillations; and dealing with chronic pain. 2 figures. 5 tables. 51 references.

Sleep Debt A Wake-Up Call Source: Diabetes Self-Management. 19(2): 67-71. March-April 2002. Contact: Available from R.A. Rapaport Publishing, Inc. 150 West 22nd Street, New York, NY 10011. (800) 234-0923. Website: www.diabetes-self-mgmt.com. Summary: Most research on sleep deprivation has focused on its cognitive (thinking) effects, but recent studies show that sleep debt affects the body as well as the mind. These studies suggest that sleep deprivation may lead to weight gain and might also worsen insulin resistance. This article offers readers with diabetes information about the impact of sleep debt. The author discusses theories as to why humans sleep, the two basic phases of sleep, six different stages of sleep, sociological changes that have resulted in less sleep, research on the effects of sleep loss, carbohydrate metabolism and how it changes with sleep loss, sleep and insulin sensitivity, and strategies to increase the likelihood of getting regular, healthy amounts of sleep. One side bar explains sleep apnea, a condition in which breathing stops repeatedly during sleep.

describes the pathophysiology of pruritus; discusses proposed etiologies; reviews an assessment for an ESRD client with pruritus; and discusses the collaborative management of pruritis in ESRD. The author notes that assessment tools are available to nurses and clients to grade the severity, frequency, distribution, and sleep deprivation experienced with the itching. Various treatments have been used to manage pruritus in ESRD with limited success. 2 figures. 34 references. (AA-M). •
Practical Strategies for Nocturia in Adults Source: Patient Care. 33(8): 147-148, 153-154, 157-158. April 30, 1999. Contact: Available from Medical Economics. 5 Paragon Drive, Montvale, NJ 07645. (800) 432-4570. Fax (201) 573-4956. Summary: This article reviews the practical care strategies that can be used to manage the adult patient with nocturia (urination at night). A common reason for visits to urologists, nocturia causes sleep deprivation and increases the risk of traumatic injury due to falls, especially among the elderly. The authors stress that, despite a variety of possible etiologies, nocturia can be classified, diagnosed, and treated with a sensible strategy that combines a little math, a voiding diary, and thorough investigative techniques. Treatment typically involves attempts to resolve either detrusor instability or bladder outlet obstruction. Although one or both of these conditions may exist in a patient who reports nocturia, the authors note that treatment may fail because of the often overlooked component of nocturnal polyuria (NP), or excessive nighttime urine production. Treatment options discussed in the article include compressive stockings, afternoon naps, diuretics, and antidiuretic hormone. The authors recommend that initial treatment should be directed at the NP component of the problem, unless its contribution is minor in comparison to the magnitude of noctural detrusor overactivity (NDO). Patient care algorithms are provided to help the reader through the process of diagnosis and treatment. 2 figures. 3 tables. 15 references.

Treating Sleep Disorders in Patients With Fibromyalgia Source: Journal of Musculoskeletal Medicine. 14(6):25-28,33-34; June 1997. Summary: This journal article for health professionals reviews current knowledge about sleep disorders in patients with fibromyalgia and the treatment strategies currently used. Sleep disturbance may be central to the fibromyalgia syndrome. Many patients have difficulty in falling and staying asleep and awaken unrefreshed with intensified morning aching. Alpha-delta sleep, in which internally triggered arousal results in delta sleep deprivation, appears responsible. Moreover, such triggers may also lead to depressed and anxious mood, fatigue, morning stiffness, and musculoskeletal pain, which, in turn, contribute to the nonrestorative sleep cycle. Success in improving sleep is greatest when general approaches and specific sleep interventions are combined. Psychotherapy, behavioral therapy, and exercise may lead to better sleep habits and symptomatic relief. Tricyclic agents improve sleep and overall functioning. Benzodiazepines administered with nonsteroidal anti-inflammatory drugs may improve sleep and decrease tenderness. 29 references and 2 tables. (AA-M).

are from participants who attended the second National Institutes of Health Conference on FMS. The conference focused on the process of pain signal transmission to perception, sleep physiology, and neuroendocrine function. Contributors in the chronic pain segment of the conference provided evidence that the central nervous system (CNS) may be primarily involved in FMS through altered pain modulatory mechanisms, presented an overview of how peripheral tissue or nerve injury often results in hyperalgesia characterized by increased sensitivity to painful stimuli, and described a model for chronic pain that suggests that FMS is a disorder characterized by abnormal CNS processing of sensory or nociceptive stimuli. Other contributors in this segment examined the role of substance P in FMS, discussed animal models of gender differences in pain and analgesia, and reviewed the evidence for cognitive behavioral interventions in the rheumatic diseases. Contributors in the neuroendocrine segment of the conference provided an overview of the physiology and phenomenology of the stress system and its complex interactions with other endocrine and neurological pathways and with the immune system, reviewed studies addressing the effects of early environmental exposures on the stress system, discussed interactions between the hypothalamic pituitary adrenal axis and hypothalamic pituitary gonadal axis, considered the responses of the sympathetic nervous and adrenomedullary hormonal systems to stressors, and reviewed research supporting an association between FMS and perturbed function of stress response systems and other neuroendocrine axes. Sleep segment topics included animal models of sleep and sleep deprivation influences on behavior and immune function in animals. 8 figures, 3 tables, and numerous references.
Federally Funded Research on Sleep Deprivation The U.S. Government supports a variety of research studies relating to sleep deprivation. These studies are tracked by the Office of Extramural Research at the National Institutes of Health.2 CRISP (Computerized Retrieval of Information on Scientific Projects) is a searchable database of federally funded biomedical research projects conducted at universities, hospitals, and other institutions. Search the CRISP Web site at http://crisp.cit.nih.gov/crisp/crisp_query.generate_screen. You will have the option to perform targeted searches by various criteria, including geography, date, and topics related to sleep deprivation. For most of the studies, the agencies reporting into CRISP provide summaries or abstracts. As opposed to clinical trial research using patients, many federally funded studies use animals or simulated models to explore sleep deprivation. The following is typical of the type of information found when searching the CRISP database for sleep deprivation: •

Summary: (provided by applicant): Recent studies have shown that mediators of inflammation, useful in predicting risk of developing cardiovascular disease in healthy asymptomatic individuals, are also increased by experimental sleep deprivation. Low basal increases in inflammatory markers are also seen in "metabolic syndrome" and we hypothesize that inadequate or insufficient sleep may be a pivotal contributing factor in the development of metabolic syndrome. We will test the hypothesis that basal changes in inflammation are actually secondary to cardiovacular factors associated with shear stress, by blocking the increase of blood pressure that is known to ensue during sleep deprivation. We expect that blocking the sleep deprivation associated increase in blood pressure will prevent the rise of inflammatory markers. We will also test the hypothesis that moderately adipose individuals are at greater risk to suffer the inflammatory and autonomic consequences of acute sleep deprivation. In screening data from this study we will also investigate the relationship between adiposity, cardiovascular fitness, Creactive protein and habitual sleep duration and quality.

Project Title: ADOLESCENT ADHD: SLEEP, SYMPTOMS, AND MEDICATION Principal Investigator & Institution: Fallone, Gahan P.; Emma Pendleton Bradley Hospital East Providence, Ri 02915 Timing: Fiscal Year 2002; Project Start 03-JUN-2002; Project End 31-MAY-2004 Summary: Attention-Deficit/Hyperactivity (ADHD) is a developmental disorder characterized by age-inappropriate levels of restlessness, impulsivity, and/or inattention that is increasingly diagnosed and treated among adolescents. Research performed in our lab has demonstrated that normal adolescents are at heightened risk for insufficient sleep and are likely to display behavioral and academic problems due to sleep restriction. Among adolescents predisposed to behavioral and academic difficulties, such as those with ADHD, the impact of shortened sleep may be amplified. Characteristics of ADHD may increase both the risk for and vulnerability to restricted sleep. In addition, restricted sleep may affect attitudes toward treatment, particularly since psychostimulant medication is a common treatment for ADHD and also an effective countermeasure for the effects of restricted sleep. The Exploratory/Developmental Grant (R21) Program was selected because the proposed project involves "research directions requiring preliminary testing and development" and uses "approaches new to a substantive area". The projects applies techniques and expertise developed describing sleep in normal adolescents to the exploration of sleep patterns and the response to restricted sleep among adolescents with ADHD. Study 1 confirms the validity of the actigraphy algorithm derived in non-ADHD samples for measuring sleep/wake states in ADHD adolescents, using laboratory-based nocturnal polysomography as the research standard. Actigraphy is then used to assist in describing self-selected sleep patterns and verifying compliance with assigned sleep schedules in Study 2. Study 2 uses a 3-phrase protocol to explore sleep- patterns, daytime sleepiness, ADHD symptoms, perceived need for medication, and medication use under self-selected, extended, and restricted sleep conditions. We hypothesize that self-selected sleep of adolescents with ADHD will be shortened on school nights. Further, under conditions of restricted sleep, we predict that adolescents with ADHD will show increased sleepiness, increased ADHD symptom severity, and increased perceived need for psychostimulant medication.

Project Title: ADULT FAILURE TO THRIVE IN LONG-TERM VENTILATOR PATIENTS Principal Investigator & Institution: Higgins, Patricia A.; None; Case Western Reserve University 10900 Euclid Ave Cleveland, Oh 44106 Timing: Fiscal Year 2002; Project Start 30-SEP-2001; Project End 30-JUN-2005 Summary: Long-term ventilator (LTV) patients represent a growing population that consumes considerable health care resources. Although the majority of critically ill patients require short-term ventilator support, LTV patients may require mechanical ventilation and thus, intensive care hospitalization for weeks or months. Prolonged mechanical ventilation usually involves a lengthy weaning period (an interval in which mechanical ventilator support is gradually withdrawn). To date, much of the research on LTV patients has focused on respiratory parameters that predict weaning outcome and mortality. There are indications, however, that factors such as malnutrition, mood state, social isolation, and poor sleep patterns may be as significant as respiratory parameters in predicting outcomes of LTV patients. Little is known about these factors in LTV patients but they are associated with adult failure to thrive (FTT), a syndrome defined as a lower than expected level of functioning that frequently is associated with nutritional deficits, depressed mood state, and social isolation. In addition to the need to assess factors that affect respiratory functioning in LTV patients, there is increasing recognition that weaning is a process, not a single incident. The proposed research will use a prospective longitudinal design to describe weaning patterns and patterns of FTTrelated variables (nutrition, mood state, social isolation, and sleep) in 300 LTV patients. Descriptive statistics will be used to characterize this patient population and graphic analysis will be used to characterize patterns of change in the variables over time and illustrate between-group variability. Multivariate analyses will investigate the relationship between FTT variables and four outcome variables: discharge disposition, length of stay, weaning outcome, and readmit status. Through identification of factors that can be modified by nurses (e.g., nutritional adequacy, sleep habits, support systems, or mood state), research about weaning and FTT variables in LTV patients will provide data for future intervention studies. It has the potential, therefore, to decrease the morbidity and mortality associated with adult FTT and long-term mechanical ventilation and it will help nurses, patients and families prepare for post-hospital care.

Project Title: AFFECT REGULATION AND ADOLESCENT BRAIN MATURATION Principal Investigator & Institution: Dahl, Ronald E.; Professor; Psychiatry; University of Pittsburgh at Pittsburgh 350 Thackeray Hall Pittsburgh, Pa 15260 Timing: Fiscal Year 2002; Project Start 23-SEP-2002; Project End 30-JUN-2006 Summary: (provided by applicant): This application describes a Research Network aimed at conceptual and methodological advances in understanding affect dysregulation in adolescence. The central theme for this project is the development and refinement of measures of affect regulation that can be used to investigate neurobehavioral systems in adolescents within a developmental framework. These include tasks that can be used in functional MRI and ERP (event-related potential) studies to examine the development of neurobehavioral systems in both clinical and normative populations of adolescents. It is also important to devise experimental paradigms that address clinically relevant and ecologically valid aspects of emotion and its regulation. This will require developing better conceptual models and formulating specific hypotheses about affective changes in developmental pathways of emotional

disorders in adolescence. The long-term goals of this work are to address clinically relevant questions-to identify developmental pathways and mechanisms of affect dysregulation that can inform treatment strategies for early-onset depression, anxiety, and other emotional disorders emerging in adolescence. We focus on adolescence because this developmental phase represents a period of increased vulnerabilities for emotional disorders, yet also presents opportunities for early intervention. Ultimately, mechanistic understanding of the development of affect regulation can lead to prevention strategies targeting high-risk populations prior to the onset of more serious emotional disorders. A deeper understanding of affect regulation in adolescence may also provide insights into behaviors such as increased sensation seeking, risk-taking, and substance use-common behaviors in adolescence that can lead to serious consequences. The specific aims of this research network are: (1) To develop and refine fMRI and ERP tasks of emotion regulation that can be used in clinical and developmental studies of older children and adolescents. (2) To develop and refine behavioral and experience-sampling methods of assessing emotion and its regulation in the natural environments of adolescents. (3) To improve heuristic models of affect regulation and dysregulation during adolescent development within a cognitive/affective neuroscience framework. (4) To provide outstanding interdisciplinary training experiences for young investigators. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: ALCOHOLISM: SLEEP AND CYTOKINES IN AFRICAN AMERICANS Principal Investigator & Institution: Irwin, Michael R.; Professor; Psychiatry & Biobehav Sciences; University of California Los Angeles 10920 Wilshire Blvd., Suite 1200 Los Angeles, Ca 90024 Timing: Fiscal Year 2002; Project Start 01-JUN-2001; Project End 31-MAR-2006 Summary: (Provided by applicant): Disturbances of sleep are prominent in alcoholic patients, persist into recovery, and have recently been found to predict those alcoholics who are most likely to relapse. This study hypothesizes that the complex cytokine network is one system that is associated with declines of sleep depth and loss of delta sleep in alcoholics. Basic observations demonstrate that pro-inflammatory and helper T cell type 1/type 2 (Thl/Th2) cytokines have a physiological role in the regulation of sleep with both somnogenic and inhibitory effects depending on the cytokine, dose, and circadian phase. However, translation of these basic mechanisms into the clinical setting is limited, and virtually no study has examined the relationships between cytokine expression and disordered sleep in patients with chronic alcohol dependence. Because evidence further indicates that African American alcoholics are at increased risk for infectious disease morbidity, disordered sleep, and abnormal cytokine expression, this study further proposes to examine the effects of alcohol dependence on sleep and on the relationships between sleep and pro-inflammatory and Thl/Th2 cytokine expression in "at risk" African American alcoholics vs. Euro-American alcoholics and controls. Sleep deprivation serves as a naturalistic probe of sleep regulatory processes to evaluate the capacity of sleep recovery in alcoholics and to test the effects of sleep on immune system functioning. The specific aims of this study are to: 1) evaluate whether alcohol dependence and African American ethnicity are associated with disturbances of sleep including loss of delta sleep and deficits in recovery of delta sleep following sleep deprivation as compared to ethnicity matched controls; 2) establish the impact of sleep on the diurnal- and nocturnal expression of pro-inflammatory-, Thl, and Th2 cytokine levels in African American and Euro- American alcoholics vs. controls; 3) determine the predictive validity of circulating interlekin-6 on delta sleep. This study will advance our

understanding of the reciprocal relationships between cytokines and sleep in alcohol dependence with implications for answering why sleep is disordered in alcoholics patients and for the development of novel treatments (e.g., cytokine antagonists) for sleep disturbance in alcoholism.

Project Title: BASIC MECHANISMS OF DELAYED SLEEP PHASE SYNDROME Principal Investigator & Institution: Wyatt, James K.; Assistant Professor; RushPresbyterian-St Lukes Medical Ctr Chicago, Il 60612 Timing: Fiscal Year 2003; Project Start 01-APR-2003; Project End 31-MAR-2005 Summary: (provided by applicant): Delayed Sleep Phase Syndrome (DSPS) describes patients who cannot fall asleep until several hours past their preferred bedtime and have extreme difficulty arising in the morning in order to attend to normal activities (e.g., school, work). This differs from traditional sleep-onset insomnia in that DSPS patients can fall asleep quickly and obtain a normal 8-hr sleep episode, but only at a much-delayed clock hour (e.g., 3 am to 11 pm). Prevalence estimates range from 0.13 percent to 7 percent. Peak onset is in the second and third decades. Possible consequences of this disorders include increased risk for accidents, impaired learning, higher use of alertness-enhancing substances, and lower productivity. The specific aims are: 1. To confirm the hypothesis that the circadian phase, as assessed from core body temperature and salivary melatonin, will be delayed, with week-to-week stability, in patients with Delayed Sleep Phase Syndrome (DSPS) relative to normal-sleeping, ageand gender-matched control subjects. 2. To test the hypothesis that DSPS patients will display the same internal phase relationships between their habitual bedtimes and wake-times, and the circadian phase markers of the minimum of core body temperature, the dim-light melatonin onset, and the fitted maximum of melatonin, but will have a larger amplitude of core body temperature and melatonin rhythms. 3. To test the hypothesis that with a sufficient increase in sleep homeostatic drive, given by the sleep loss incurred during a constant routine protocol, patients with DSPS syndrome will be able to obtain a normal sleep episode at a clock time 3 hours earlier than their habitual, delayed schedule. However, unlike normal control subjects, patients with DSPS return to their baseline pattern of inability to fall asleep at this earlier hour, on a second recovery night of sleep following the constant routine. The proposed investigations fulfill the criteria for the R21 mechanism by offering innovation (e.g., first measurement of temporal stability of phase delay, first measurement of full circadian and sleep parameters), bringing approaches new to an area (e.g., constant routine protocol), and initiating the first step in programmatic research for this investigator (basic mechanisms, diagnostic protocols, and evidence-based treatments for circadian phase disorders, beginning with DSPS).

advocate the value of and need for the humane and judicious use of animal models to expedite the elucidation of causes, treatments, cures, and prevention of human disease. The PI's past and current service and administrative responsibilities has limited the time available for introducing new research methodology into the laboratory, for mentoring students and other trainees, and for actively participating in collaborative research as a specialist in mouse pathobiology. The relief from institutional service offered by this award will allow the PI the time to accomplish the following Specific Aims: 1) to develop skills in new analytic (microarray technology) and behavioral [sleep deprivation (SD), depression, and anxiety] methodologies for application to interests in delineating the immune modulatory role of sleep; 2) to increase mentoring efforts directed toward both students and faculty; and 3) to initiate collaborations that will promote and support the study of mouse models of human disease. Research goals for this proposal focus on defining the health implications of inadequate sleep. Sleepiness and poor sleep quality broadly influence measures of general health status, particularly impacting perceptions about energy, fatigue, and self-sufficiency. Sleep fragmentation, non-restorative sleep, and inadequate sleep are commonly assumed to adversely impact host defense capabilities. However, these relationships have not been empirically defined. Some studies in animals suggest that inadequate or poor-quality sleep may increase susceptibility to disease, exacerbate symptoms of disease, or delay recuperation. The development and use of an appropriate animal model to evaluate the relationships between sleep, sleep loss, and susceptibility to or recuperation from infectious or inflammatory disease is the primary research goal of this application.

Project Title: BEHAVIORAL INTERVENTION FOR INSOMNIA IN OLDER ADULTS Principal Investigator & Institution: Epstein, Dana R.; U.S. Carl T. Hayden Vet Affairs Med Ctr Affairs Medical Center Phoenix, Az 85012 Timing: Fiscal Year 2002; Project Start 15-SEP-1998; Project End 31-JUL-2004 Summary: Insomnia is a prevalent health problem and frequent complaint of older adults. The majority of research in the non-pharmacological treatment of insomnia has focused on young and middle-aged adults while only a small number of studies have evaluated treatment for late-life insomnia. Knowledge of the intervention or combination of interventions best suited for older adults is limited. Therefore, the purpose of the study is to evaluate and compare the efficacy of single interventions (stimulus control instructions, sleep restriction therapy) and multi- component intervention (stimulus control instructions and sleep restriction therapy) for sleep maintenance insomnia in community dwelling older adults. The study will incorporate multiple sleep measures to determine the short and long-term effects of the interventions on sleep outcomes. The efficiency of the interventions, intervention dosage, compliance with treatment and clinical significance of the outcomes will be addressed. The long-term goal of the research is to provide clinically significant and applicable non-pharmacological, theory driven intervention that effectively addresses the specific insomnia problems of older adulthood. One hundred eighty community dwelling older adults with sleep maintenance insomnia will participate in a randomized controlled study using a waiting-list design. Subjects will be randomly assigned to one of the four conditions: (a) multi- component intervention, (b) stimulus control instructions, (c) sleep restriction therapy, or (d) waiting-list control. There will be a 2week baseline period, a 6-week treatment period, and a 2-week post- treatment period. The waiting-list subjects will receive treatment after the immediate treatment groups

Project Title: BIOPSYCHOSOCIAL MODEL OF SLEEP EDUCATION Principal Investigator & Institution: Owens, Judith A.; Associate Professor; Rhode Island Hospital (Providence, Ri) Providence, Ri 02903 Timing: Fiscal Year 2002; Project Start 01-SEP-1998; Project End 31-AUG-2004 Summary: (Adapted from the Applicant's Abstract) The purpose of this application is to develop, implement, and evaluate an innovative medical school curriculum at the Brown University School of Medicine in sleep and its disorders. Curriculum organization is based on a biopsychosocial approach to sleep and emphasizes two fundamental educational goals for students: acquisition of a basic foundation in sleep physiology and clinical diagnostic skills related to sleep and sleep disorders in both adults and children, and translation of these basic knowledge, skills, and attitudes about sleep into an organized and comprehensive clinical approach to sleep and sleep disorders in infants, children, and adolescents. Curriculum development will be guided by specific educational principles, namely adult learning theory and instructional technology process, as well as by integration into the Brown MD 2000 competencybased curriculum. Curriculum content will be organized into eight modules, with each addressing a specific sleep issue on a pre-clinical and/or clinical medical school level. Specific educational objectives include the development of a pediatric sleep history instrument; a self-study, self-health and awareness program for medical students on sleep, sleep habits, and the effects of sleep deprivation; development of several video vignettes on sleep problems in children and adolescents; and development of a community education project with medical students giving presentations on adolescent sleep needs and drowsy driving. The curriculum is intended to be modifiable for use in primary care (pediatrics, family medicine) and mental health (child psychology, psychiatry) training programs and other medical school settings.

Project Title: CHOLINERGIC PHENOTYPE IN MURINE MODELS OF SLEEP Principal Investigator & Institution: Lydic, Ralph B.; Bert La Du Professor of Anesthesia; Anesthesiology; University of Michigan at Ann Arbor 3003 South State, Room 1040 Ann Arbor, Mi 481091274 Timing: Fiscal Year 2002; Project Start 30-SEP-1999; Project End 31-AUG-2003 Summary: Disorders of sleep are estimated to affect 70 million Americans. Sleep is a product of the brain and the cellular mechanisms regulating sleep are incompletely understood. This application is submitted in response to RFA HL-99-001, seeking to stimulate improved molecular, cellular, and systems approaches to investigate sleep in mice. The approach of this application is to use the C57BL/6J mouse (B6) for phenotype characterization of neuronal systems known in other mammals to regulate sleep. The long-term objectives are to advance scientific knowledge by providing data on cholinergic neurotransmission not presently available for mouse. The focus of this application is on muscarinic cholinergic receptors (mAChRs), adenosine A1 receptors, and their associated guanine nucleotide binding proteins (G proteins). Since mammalian sleep is known to be regulated by cholinergic neurotransmission, localizing mAChR subtypes in mouse brain is an essential step for phenotype characterization of the mouse

as a model for sleep neurobiology. Aim 1 will use in vitro autoradiography to localize and quantify mAChR subtypes in nuclei of B6 mouse forebrain and brain stem. These studies will test the hypothesis that mAChRs in mouse brain stem, basal forebrain, and preoptic hypothalamus parallel the distribution of mAChRs in rat and cat. Activation of mAChRs initiates a transmembrane signal transduction cascade mediated by G proteins. Thus, Aim 2 will use autoradiography to quantify G proteins in the brain regions described by Aim 1. Aim 2 will provide the first phenotype data in B6 mouse localizing cholinergically activated G proteins in brain regions known to regulate sleep and breathing. Concentration-response and antagonist blocking conditions will make it possible to test the hypothesis that G proteins in these nuclei are activated by mAChR stimulation. Cholinergic neuron excitability is modulated by the somnogenic factor adenosine. Aim 3 will test the hypothesis that sleep deprivation alters muscarinic and adenosinergic activation of G proteins in sleep- and breathing-related brain regions. Aim 4 will extend characterization of mouse cholinergic phenotype to the cerebral cortex. Cortical electroencephalographic (EEG) activity comprises a defining measure of sleep, and the EEG is cholinergically modulated. Aim 4 will test the hypothesis that acetylcholine release in frontal association cortex is modulated by muscarinic cholinergic autoreceptors. Aim 4 will further determine the subtype of cortical muscarinic autoreceptor. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: CIRCADIAN AND SLEEP/WAKE ASPECTS OF NOCTURNAL ASTHMA Principal Investigator & Institution: Shea, Steven A.; Assistant Professor; Brigham and Women's Hospital 75 Francis Street Boston, Ma 02115 Timing: Fiscal Year 2002; Project Start 01-APR-2000; Project End 31-MAR-2004 Summary: There exists a disproportionately high frequency of asthmatic events during the latter half of the usual sleep episode. Patients with nocturnal asthma demonstrate increased morbidity and mortality relative to other patients with asthma. Diurnal studies involving repeated measurements during the sleep/wake cycle, sleep deprivation or shift work suggest the existence of separate sleep and circadian dependent effects on bronchoconstriction. Recent data from established circadian protocols clearly indicate significant circadian rhythms in pulmonary function and respiratory control in healthy subjects, and that indices of airways inflammation have a diurnal rhythm (circadian and sleep/wake cycles not separated) in patients with asthma and healthy controls. The primary aim is to test the hypothesis that asthma severity is affected by separate circadian influences (independent of sleep) and sleep/wake cycle influences (independent of circadian rhythm). The principal dependent variables include bronchoconstriction (spirometry and airways resistance) and asthma symptoms (validated questionnaire and usage of any rescue medication). To overcome methodological problems with previous studies a 'forced desynchrony' protocol will be used, wherein subjects sleep and wake episodes occur at all phases of the circadian cycle. This will be accomplished by scheduling a recurring artificial day length of 28 hours throughout a 10-day protocol in healthy subjects and patients with nocturnal asthma. The specific aims will test the hypotheses that 1) bronchoconstriction is influenced by separate circadian and sleep/wake effects; 2) bronchoconstriction is affected by circadian or sleep/wake influences on airway inflammation; and 3) bronchoconstriction is affected by circadian or sleep/wake influences on sympathovagal balance.

Project Title: CIRCADIAN RHYTHMS AND SLEEP IN FAMILIAL DSPS AND ASPS Principal Investigator & Institution: Zee, Phyllis C.; Professor; Neurology; Northwestern University Office of Sponsored Research Chicago, Il 60611 Timing: Fiscal Year 2003; Project Start 01-SEP-2003; Project End 30-JUN-2007 Summary: (provided by applicant): Tremendous progress in the past few years has led to the identification of several circadian clock genes. This now makes it possible to determine how alterations of human circadian clock genes, and their expression, could lead to differences in circadian and sleep/wake cycle phenotypes. Of particular interest for understanding genetics of the human circadian system are individuals with sleep phase disorders, such as delayed sleep phase syndrome (DSPS) and advanced sleep phase syndrome (ASPS), because recent studies indicate a genetic basis for these disorders. While it is assumed that both ASPS and DSPS are disorders of circadian timing, little is known about how the circadian clock system, or its interaction with sleep processes, are affected in these individuals. Therefore, one of the overall objectives of the proposed studies is to determine the properties (e.g., phase, amplitude, and period) of circadian rhythms under entrained and constant routine conditions in familial ASPS or DSPS. A second objective is to test hypotheses that could explain the mechanisms (i.e., response to light, alterations in period) that underlie the phase disturbance in these conditions. Although it is commonly assumed that sleep per se is normal in the circadian sleep phase disorders, there is some evidence to suggest that the regulation of sleep homeostasis may be altered in DSPS. Therefore, a third specific aim of the proposed studies is to define the sleep-wake characteristics via EEG/polysomnography in DSPS and ASPS subjects during baseline sleep and recovery sleep following sleep deprivation in which the subjects are allowed to begin recovery sleep at a normal or an abnormal circadian time. The approach of studying familial DSPS and ASPS provides a unique opportunity to clearly define circadian and sleep phenotypes in individuals whose sleep/wake cycle is due to intrinsic biological changes and not merely a result of environmental influences and societal pressures. The results of these studies are expected to not only lead to new insights into the regulation of sleep and circadian rhythms in humans, but also to new therapeutic approaches for the treatment of sleep/wake cycle disorders.

Project Title: CONSEQUENCES OF MDMA IN HUMANS Principal Investigator & Institution: Tancer, Manuel E.; Professor; Psychiatry & Behav Neuroscis; Wayne State University 656 W. Kirby Detroit, Mi 48202 Timing: Fiscal Year 2002; Project Start 30-SEP-2001; Project End 31-AUG-2004 Summary: (provided by the applicant): 3,4-methylenedioxymethamphetamine (MDMA or "ecstasy") use has soared in the past few years despite increasing scientific evidence of adverse consequences. MDMA is perceived as safe by many users despite media reports of deaths and serious medical complications. The mechanism(s) underlying the reported consequences of MDMA use (e.g. hyperthermia, disrupted sleep, mood and anxiety problems) are not known. The goal of the proposed studies is to define both the acute and chronic consequences of MDMA use in humans. Controlled laboratory administration of MDMA (2 mg/kg) will be used to assess the acute effects of MDMA on physiological (thermoregulation, metabolism, and sleep), psychological (mood, anxiety), and cognitive parameters. For an evaluation of chronic effects of MDMA use on mood and anxiety symptoms and cognitive measures, a longitudinal study will be conducted. Specific Aim 1 is to determine the effect of MDMA (compared to placebo) on

thermoregulation and metabolism under different ambient temperatures (18 and 30 deg C) or under different activity levels (bed rest and moderate exercise [40 percent max V02] for 60 minutes at 23 deg C). Specific Aim 2 is to directly measure the effect of MDMA (compared to placebo, d-amphetamine, or partial sleep deprivation) on sleep time and architecture, cognitive function, mood, subsequent day mood, sleepiness, and cognitive function. Specific Aim 3 is to longitudinally measure cognitive function and psychopathology in novice (1-5 exposures) MDMA users over a two-year period, following an extensive baseline evaluation. The long-term goal of these studies is to provide reliable information about the extent and basis for MDMA-related acute and long-term adverse health consequences. This information will be applied to develop and test strategies to block the effects or at least minimize consequences. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: CORE--ANIMAL BEHAVIOR AND INFORMATICS Principal Investigator & Institution: Davies, Richard O.; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2003; Project Start 15-SEP-2003; Project End 31-AUG-2008 Summary: The Animal Behavioral and Informatics Core will provide support to the basic science animal projects in the Specialized Center of Research (SCOR). The core will have the following specific functions: a. To support studies of behavior for the protocols in the animal projects. This will involve studies of rest/activity, computer processing of data and ensuring that the animal being studied is normal and not a behavioral outlier. The Core staff will assist staff in the individual projects in conducting sleep (rest) deprivation studies and in sacrifice of animals. For studies involving sleep/wake recording by electroencephalographic (EEG) and electromyographic (EMG) means, the Core staffwill assist project staff in this activity and be responsible for hand scoring of all EEG/EMG records. b. To provide data base support to investigators in the SCOR using the Mouse Informatics system to allow investigators to archive and retrieve information on mouse behavior, details of animal health, method of sacrifice, tissue dissection and amount of RNA or protein obtained from microdissection techniques. c. To continue further development of the Mouse Informatics Center, and developing an Informatics Center for studies in Drosophila. d. To characterize sleep/wake patterns by EEG/EMG recording in a large sample of C57BL/6J mice during the behavioral protocols to be conducted, including the response to different durations of sleep deprivation. e. To continue participation in development of improved non-invasive ways of phenotyping mouse sleep. This will involve recording of rest/activity and analysis of digital video images with validation studies comparing the data obtained with definitive scoring of sleep by EEG/EMG methods.

Project Title: DETERMINANTS OF COMPENSATORY SLEEP PHENOTYPE IN MICE Principal Investigator & Institution: Dement, William C.; Psychiatry and Behavioral Sci; Stanford University Stanford, Ca 94305 Timing: Fiscal Year 2002; Project Start 30-SEP-1999; Project End 31-AUG-2003 Summary: Increased NonREM sleep time, sleep episode duration, and EEG delta power reflect normal compensatory sleep responses (CSR) to extended wakefulness and constitute a central tenet of sleep physiology- that sleep is homeostatically regulated. In rats, catecholamine releasing stimulants (e.g., methamphetamine) also potently induce
16
Sleep Deprivation
CSR. Wakefulness induced by selective dopamine reuptake blockers (e.g., GBR12909), however, produces no CSR, suggesting dopamine transporter involvement in sleep homeostatic mechanisms. To further investigate this possibility we will first confirm that these phenomena generalize to mice. We will then investigate stimulant interactions with sleep homeostasis in mice with null mutations of the dopamine transporter allele and in Cast/Ei mice. Our preliminary data show that Cast/Ei mice have less sleep time and attenuated compensatory sleep responses to sleep deprivation and methamphetamine-induced wakefulness relative to C57BL/6 mice. Using high throughput automated sleep scoring technology, we will investigate the involvement of the dopamine transporter in sleep homeostasis, and will begin to identify the genetic underpinnings of sleep regulatory variation between C57BL/6 and Cast/Ei mice. Four interrelated specific aims will test the hypotheses that: (1) mice (C57BL/6J) exhibit compensatory sleep responses to behavioral SD or methamphetamine-induced wakefulness, but do not exhibit compensatory sleep responses to wakefulness induced by the selective dopamine reuptake blocker GBR12909 or adenosine receptor antagonists, akin to that observed in laboratory rats; (2) the cell membrane dopamine transporter is necessary for the wakefulness-promoting effects of GBR12909, methamphetamine, caffeine and cyclopentyltheophylline.; (3) the cell membrane dopamine transporter is a functional constituent of sleep homeostasis and is therefore necessary for compensatory sleep responses to sleep deprivation (SD). We will also test the hypothesis that (4) three sleep phenotypes that differ between C57BL/6 mice and Cast/Ei mice - i.) total sleep time, ii.) compensatory sleep response to behavioral SD, and iii.) compensatory sleep response to wakefulness induced by methamphetamine treatment-- are not regulated by distinct genetic loci. Finally, we propose a set of pilot studies that will test if the cell membrane serotonin transporter is necessary for compensatory sleep responses to sleep deprivation and wakefulness induced by methamphetamine. The proposed research will advance our understanding of dopaminergic stimulant interactions with sleep homeostasis, CSR mechanisms, and genetic determinants of phenotypic variation in sleep homeostasis.

Project Title: DETERMINING THE GENETICS OF RESTLESS LEGS SYNDROME Principal Investigator & Institution: Earley, Christopher J.; Associate Professor; Neurology and Neurosurgery; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2002; Project Start 01-MAY-2000; Project End 31-MAR-2004 Summary: Restless Legs Syndrome (RLS) is a common sleep disorder especially for older adults. It is characterized by episodes of distressing sensations in the limbs, generally the legs, which are relieved by movement of the affected extremity. It is generally progressive starting at various ages but becoming both more common and more distressing for older adults. Symptoms become so severe, particularly for older adults, that in many cases activities in which movements are seriously limited and cognitive stimulation is minimal become difficult if not impossible. In addition, individuals usually have great difficulty initiating and maintaining sleep and experience severe, chronic, disabling sleep deprivation. Several reports have been published in which multiple family members are affected with RLS. Investigators have surmised that transmission of RLS follows a Mendelian autosomal dominant pattern. To date, however, no systematically ascertained family study of RLS has been published in the literature. Likewise, there are no studies of the mode of transmission for RLS. Despite this, there have been three unpublished attempts to use linkage analysis to find the
Studies
17
gene(s) causing RLS. No vulnerability loci have been found. Our pilot data from 96 families of RLS patients show there is indeed a strong familial component to RLS, particularly in relatives of probands with onset earlier than 45 years of age. In these families, risk for RLS in first-degree relatives was 23.6 percent (by history as reported by the proband). This is significantly elevated over the 3.5 percent of first-degree relatives of unaffected controls found to be affected with RLS (also by history). Even within this early-onset group, there appear to be familial and non-familial groups. The Aims of the current proposal are: (1) to use direct interview methods for assessing the presence of RLS in all first- and second-degree relatives of 130 probands with RLS and compare these rates to those found in a control sample assessed with the same methodology; (2) to test the hypothesis There exists a more familial, early-onset subgroup of RS and to determine the optimum age of onset for defining such a group: and (3) to deduce the most likely mode of genetic inheritance using segregation analysis on diagnostic data of the estimated 1700 family members in the RLS sample and to perform this analysis separately for the early and late onset RLS probands. The ultimate goal of this research would be to provide reliable data from a carefully characterized family study sample with attention to evaluating age-of-onset determination of two different phenotypes as the needed basic groundwork for research to determine the genetics of RLS, a relatively common and often severely distressing disorder.

Project Title: DEVELOPMENT OF SLEEP HOMEOSTASIS IN THE DEVELOPING RAT Principal Investigator & Institution: Heller, Horace Craig.; Professor and Chair; Biological Sciences; Stanford University Stanford, Ca 94305 Timing: Fiscal Year 2002; Project Start 03-JUL-1998; Project End 31-DEC-2003 Summary: (Adapted from applicant's abstract): This proposal will investigate the development of homeostatic sleep mechanisms and emergence of distinct arousal states in the neonatal rat. Arousal states cannot be identified by EEG parameters early in postnatal development, thus, arousal states in neonates are defined behaviorally as active sleep (AS) and quiet sleep (QS). AS and QS are generally considered homologous to REM and NREM sleep in adults, however, we found that EEG slow wave activity (SWA) occurs as often during AS as it does in QS at postnatal day 12 (P12). Thus, AS may not be an immature form of adult REM sleep, rather, it may be an undifferentiated state of the nervous system out of which NREM sleep emerges first and REM sleep second. We will test this hypothesis by determining when additional physiological parameters (e.g., respiratory patterns, electro-oculogram (EOG), brain and skin temperatures, and myoclonia) coalesce and form identifiable arousal states. We have developed a system for simultaneous recording of EEG, EMG, and behavioral sleep (by videotape) in neonatal rats continuously from P12 to P30. We found that adult-like responses to sleep deprivation (SD) were not present until P24; prior to that age, SD elicits increases in total sleep time (TST) without affecting the intensity or amount of SWA. From P12-P24, SWA increases progressively beyond adult levels, yet is not affected by SD. Thus, critical components of adult sleep homeostatic mechanisms must be absent prior to P24. Convergent lines of evidence support a role for adenosine in regulating SWA; however, its link to homeostatic mechanisms is unknown. We found that the adenosine A~ receptor agonist, N6-Cyclopentyladenosine (CPA), mimics the effects of SD in both adult and neonatal rats. Furthermore, CPA elicits SWA at ages (P16 and P20) when 3 h of SD have no effect on SWA. Thus, A1 receptors are present and functional but apparently not activated by SD. This proposal will investigate arousal

state emergence, development of sleep homeostasis, and adenosinergic regulation of sleep homeostasis in neonatal rats. These studies will contribute significantly toward clinical studies on sudden infant death syndrome (SIDS) because they investigate the mechanisms by which arousal and, hence, failure to arouse, from sleep develop.

Project Title: DEVICE TO CANCEL SECONDHAND SNORING & FOR SLEEP RESEARCH Principal Investigator & Institution: Vosburgh, Frederick; Sr Staff Fellow, Lab of Biochemistry; Nekton Research, Llc 4625 Industry Ln Durham, Nc 27713 Timing: Fiscal Year 2004; Project Start 15-JAN-2004; Project End 30-JUN-2004 Summary: (provided by applicant): Some 25% of adults snore habitually, creating secondhand problems for those trying to sleep nearby (bed partners), frequently including chronic sleep deprivation. Sleep deprivation can impose a significant burden on health, cognition, driving ability, and social relationships. In the proposed Phase I effort, we will conduct a proof of concept (POC) test of technology for unobtrusively canceling the sound of snoring at the ears of a bed partner while permitting natural hearing of other sounds. The POC effort will comprise; 1) assembling a test system, 2) determining an adaptive situational transfer function, 3) quantifying real-time snore canceling performance of the Phase I device and algorithm and investigating sensor fusion enabling multi-transducer embodiments, and 4) working with our academic collaborator to secure IRB approval for Phase II activities involving human subjects. In Phase II, a device will be developed having consumer and sleep research applications. By selectively canceling snoring sounds, the envisioned device will enable a bed partner to sleep more and more peacefully. The envisioned device also is the basis for a new sleep research tool to study the impact of secondhand effects of snoring, as well as automating and simplifying the gathering and analyzing of breathing sound and other data useful in sleep research.

Project Title: DIFFERENTIAL VULNERABILITY TO MORBIDITIES OF SLEEP APNEA Principal Investigator & Institution: Veasey, Sigrid C.; Professor; Medicine; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2002; Project Start 30-SEP-2000; Project End 31-JUL-2004 Summary: (Adapted from the applicant's abstract) Obstructive sleep apnea (OSA) affects over 2% of the adult population in the United states and is associated with significant neurobehavioral and cardiovascular morbidities. The morbidities of OSA relate at least in part to sleep fragmentation and intermittent hypoxia, both consequences of sleeprelated collapse of the upper airway. In humans with OSA, there is significant variance in the manifestation of both the neurobehavioral and cardiovascular consequences. This variance in morbidity is only partially explained by the severity of disease. These investigators believe that vulnerability tot he morbidities of OSA is, in part, geneticallydetermined. For this proposal, they will focus on the substantial neurobehavioral consequences of sleep apnea. To begin to determine the genetic mechanisms contributing to the differential vulnerabilities, they will look separately at sleep fragmentation and chronic intermittent hypoxia (CIH) responses in inbred strains of mice. They will first expand the phenotypical response to sleep disruption to include, not only electroencephalographic changes, but also to characterize the neurobehavioral

19
responses: sleepiness, changes in motor activity, learning, short and long term memory, vigilance and recovery for each of these parameters following exposure to sleep fragmentation or CIH. Responses to CIH will be characterized in the same manner. A high throughput screening algorithm will be validated against the full phenotypic responses to detect not only mutant sleep responses but mutant neurobehavioral responses characteristic of OSA. Therefore, this work provides an essential foundation for determining gene function in the susceptibility of sleepiness, impaired cognation and behavioral responses caused by obstructive sleep apnea.

Project Title: DRUG ABUSE, SLEEP AND COGNITION Principal Investigator & Institution: Hobson, J A.; Professor; Massachusetts Mental Health Institute 74 Fenwood Rd Boston, Ma 02115 Timing: Fiscal Year 2002; Project Start 01-SEP-1999; Project End 30-JUN-2004 Summary: Many dysfunctional aspects of drug abuse can be understood and effectively treated only when the links between changes in levels of neuromodulators, sleep, and cognition are well described and analyzed. This proposal focuses on the cognitive effects of two drug classes, the psychostimulants (here cocaine) and the selective serotonin reuptake inhibitors or SSRIs (here paroxetine), both of which are known to potentiate the monoaminergic neuronal systems of the brain. Drawing upon our basic neurobiological knowledge and theories of sleep and cognition, we have generated specific predictions on the sleep and neuromodulatory factors mediating the cognitive effects of cocaine abuse. We will combine our validated ambulatory sleep monitor, the Nightcap, with cognitive tests that can be presented and performed on the same Macintosh computer that analyzes sleep measurements. The study of drug effects on sleep and cognition will be made considerably more economical and naturalistic by the application of this integrated ambulatory system. We plan to use this ambulatory monitoring capability at two unique research facilities, the cocaine self-administration laboratory of the Substance Use Research Center at Columbia Medical School and the Harvard Laboratory of Neurophysiology sleep laboratory, to study how sleep, monoaminergic mechanisms, and their interactions may mediate the cognitive sequelae of cocaine abuse. At the heart of this proposal is the idea that the monoaminergic drugs of abuse such as cocaine, first potentiate but then later impair the neuromodulatory dynamics of the wake-sleep cycle with ultimately deleterious effects upon cognitive functioning. We propose a series of studies which are theory-driven and which test specific hypotheses that will allow us to isolate and describe the interrelated effects of sleep and monoaminergic neuromodulators on the known negative cognitive effects of cocaine use and abstinence. In a set of seven complementary protocols, we will compare the individual and combined effects on sleep and cognitive performance of repeated cocaine administration and abstinence, administration and discontinuation of paroxetine, and REM sleep deprivation. The proposed research will answer fundamental questions regarding the cognitive benefits of sleep and how these benefits are lost when drugs are abused.

Sleep Deprivation
Summary: (provided by applicant): Heart disease, vascular disease and respiratory sleep disturbance are common and complex disorders with interactions among the cardiovascular, immune, neuroendocrine, sleep and circadian systems. Because inflammation in response to acute and chronic stress responsible for tissue damage associated with disease, recent efforts to understand mechanisms underlying these disorders have lead to studies that investigated inflammatory markers. These research efforts have revealed that high plasma levels of several novel inflammatory markers-cell adhesion molecules and pro-inflammatory cytokines-predict cardiovascular morbidity and mortality. High plasma levels of these markers are also reported to be associated with the severity of sleep apnea. A variety of stressors have been reported to initiate the inflammatory response, however, whether the stress of sleep deprivation also produces higher levels of these novel inflammatory markers is unknown. The current grant application takes an integrative physiological approach to understanding health consequences of sleep deprivation by forming new collaborations between experts in vascular physiology, neuronimmunophysiology, neuroendocrinology and sleep and circadian physiology. We are requesting funds to analyze existing biological specimens that were collected under controlled laboratory conditions from healthy women and men who underwent baseline sleep and wakefulness recording and 40 hours of total sleep deprivation. We propose to test the following specific hypothesis: 0 that acute total sleep deprivation will increase circulating levels of proinflammatory cell adhesion molecules; and ii) that acute total sleep deprivation will increase circulating levels of pro-inflammatory cytokines. We also propose to measure stress hormones to determine the relationship between changes in inflammatory cell adhesion molecules, cytokines and stress hormones during sleep deprivation and during baseline sleep. Because sleep loss is an independent risk factor for heart disease and chronic sleep loss is a consequence of sleep apnea, the results of the proposed study could have important implications for understanding the molecular mechanisms underlying these disorders and their association with sleep loss. This work could also have a significant impact on our understanding of the health consequences of sleep loss, which would have implications for public health and safety.

Project Title: EFFECTS OF SHORT AND LONG NIGHTS ON THE CIRCADIAN CLOCK Principal Investigator & Institution: Eastman, Charmane I.; Professor of Psychology; Rush-Presbyterian-St Lukes Medical Ctr Chicago, Il 60612 Timing: Fiscal Year 2003; Project Start 01-SEP-2003; Project End 30-JUN-2007 Summary: (provided by applicant): It is widely recognized that humans in modern society do not get the sleep they need. This chronic sleep debt significantly degrades productivity, increases accident rates and has been linked to poor health and increased risk of death. Humans are exposed to a light dark (LD) cycle created by natural and artificial light alternating with sleep. Sleep duration determines the length of dark in the daily LD cycle. However, the effects of repeated short dark periods (short nights) on the human circadian system remain unknown. It has been proposed that mammals have a complex circadian pacemaker, consisting of an evening oscillator, that regulates the onset of melatonin secretion, and a morning oscillator, that regulates the offset of melatonin secretion. In short summer nights (longer photoperiods), the phase relationship between the evening and morning oscillators is decreased, which shortens the duration of the nocturnal melatonin profile, in turn regulating appropriate seasonal changes. Other animal work shows that the range and amplitude of the light phase
Studies
21
response curve is decreased in short nights. We propose to investigate the effects of short and long nights on the human circadian system, by keeping subjects in bed, in the dark, for either 6 or 9 hours per night. We will determine if the duration of the melatonin rhythm in dim light compresses after a history of short nights, and expands after a history of long nights, thus revealing that the circadian pacemaker has a memory of the previous night length. We will also determine if a history of short nights reduces the phase shifting response to light. Our goal is to determine the extent to which the chronic sleep debt in modern society is altering the functioning of the human circadian system. This work has important implications for the sleep deprived general population and for jet travelers and night shift workers who must phase shift their circadian rhythms in order to adjust to phase shifts in their light/dark cycle.

Project Title: EFFECTS OF TREATING OBSTRUCTIVE SLEEP APNEA IN EPILEPSY Principal Investigator & Institution: Malow, Beth A.; Associate Professor; Neurology; University of Michigan at Ann Arbor 3003 South State, Room 1040 Ann Arbor, Mi 481091274 Timing: Fiscal Year 2002; Project Start 15-SEP-2002; Project End 31-JUL-2003 Summary: (provided by applicant): Epilepsy affects approximately 2.5 million Americans, resulting in substantial disability. Because up to 30% of patients with epilepsy continue to have seizures despite appropriate treatment with antiepileptic medications, additional interventions to improve seizure control are needed. One approach to improving seizure control is to treat coexisting sleep disorders, such as obstructive sleep apnea. Obstructive sleep apnea (OSA) may exacerbate seizures via sleep fragmentation, sleep deprivation, or other pathophysiological processes that have not yet been determined. The investigators recently documented that OSA is common in epilepsy patients with seizures refractory to medical treatment. In addition, preliminary data in the form of retrospective case series by the investigators and others have suggested that treatment of OSA may improve seizure control. However, no prospective studies have been done to verify these findings. Proof that treating OSA is effective in reducing seizure frequency will require a multicenter Randomized Clinical Trial (RCT). This large RCT will test the hypothesis that treatment of OSA in patients with epilepsy refractory to medical treatment will reduce seizure frequency. In addition, the RCT will assess the impact of treating OSA on health-related quality of life and on daytime sleepiness, common concerns in epilepsy patients that are often attributable to antiepileptic medications or to frequent seizures rather than to a coexisting sleep disorder. The proposed aims of the Pilot Clinical Trial (PCT) are to determine critical information for the design of the RCT to allow for the testing of the above hypotheses in the RCT. In the PCT subjects 18 years and older with 4 or more seizures per month who meet survey criteria for OSA and other study criteria will be recruited at 3 different sites from epilepsy patients seen in clinical settings. A total of 60 subjects will be observed longitudinally through PSG confirmation and treatment of OSA and randomized to either therapeutic continuous positive airway pressure (CPAP) or sub-therapeutic (placebo or sham) CPAP in order to determine tolerability. Rates of adherence to therapeutic and sham CPAP and dropout rates due to antiepileptic drug changes during the treatment phase will be estimated. Specifically, the proposed PCT will: 1. Evaluate screening ranges on the Sleep Apnea scale of the Sleep Disorders Questionnaire (DA/SDQ), a survey instrument that is used to determine whether subjects are eligible for inclusion into the RCT. 2. Determine the necessity of performing two nights of PSG in patients with epilepsy. A second night of study increases the cost and may decrease
22
Sleep Deprivation
recruitment in the RCT, but may be important to include given the night-to-night variability in the PSG and the potential for seizure occurrence during recordings. The working hypothesis is that one night of PSG will be sufficient for the RCT. 3. Determine rates of adherence to therapeutic and sham CPAP, dropout rates due to antiepileptic drug changes, and response rates will provide valuable data for planning the RCT. 4. Develop quality control measures to ensure accurate and consistent data collection among sites in the RCT, including aspects related to remote data entry and standardization of performance and interpretation of PSG studies across sites.

Project Title: EXERCISE & SLEEP: A CLINICAL TRIAL IN MENOPAUSAL WOMEN Principal Investigator & Institution: Davis, Jean E.; Center for Health Research; Wayne State University 656 W. Kirby Detroit, Mi 48202 Timing: Fiscal Year 2003; Project Start 15-SEP-2003; Project End 30-JUN-2006 Summary: (provided by applicant): An estimated 80 percent of the approximately 50 million postmenopausal women in the United States have complaints of disrupted sleep patterns characterized by sleep loss. Several studies show that a relative lack of estrogen interferes with optimal sleep and exogenous estrogen replacement improves sleep maintenance. However, it has been reported that less than 15 percent of postmenopausal women use estrogen replacement therapy. A growing body of evidence demonstrates that exercise improves self-reported sleep quality in postmenopausal women. The longrange goal of this research is to develop an exercise prescription that will improve the sleep of postmenopausal women. The specific objective of this research application is to determine the effects of a moderate intensity, home-based exercises program on objective sleep parameters, self-reported sleep quality, and daytime sleepiness. The central hypothesis is that a regular exercise program will improve the sleep architecture and sleep continuity patterns, subjective sleep quality, and daytime sleepiness in estrogen-deficient postmenopausal women. Employing an experimental, repeated measures, randomized treatment control group design, forty postmenopausal women who are estrogen deficient, sedentary, and have a sleep maintenance disorder will be randomly assigned to one of two conditions; an exercise group or a control group. The exercise will be home-based, moderate intensity walking with a frequency of 5 times per week and a duration of 30 minutes per session. Measurements of sleep architecture, sleep continuity, sleep quality and daytime sleepiness will be obtained at baseline and after the 16-week exercise or non-exercise period. Data on potential mediating variables of estradiol and circadian core body temperature rhythm will also be collected. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Jackson Fdn for the Adv Mil/Med Rockville, Md 20852 Timing: Fiscal Year 2002; Project Start 01-APR-2000; Project End 31-MAR-2004 Summary: (Adapted from Applicant's Abstract ) Sleep is ubiquitous among mammals and essential for life. More than seventy types of sleep disorders chronically affect millions of Americans in all age groups. Recently, it was shown that the primary fattyacid amide, oleamide, is a mediator of sleep and may thus contribute to the genesis of sleep disorders. Oleamide accumulates in cerebral spinal fluid during sleep deprivation and induces profound motor quiescence and a sleep-like state upon administration.
Studies
23
Primary fatty-acid amides represent a new class of receptor-active signaling molecules whose biogenesis is unknown. Understanding the pathway involved will offer targets for the therapeutic interventions for treating sleep disorders. Recently, we established in vitro that peptidylglycine-alpha-amidating monooxygenase (PAM; EC 1.14.17.3) is able to catalyze the formation of oleamide. PAM is known for its role as the rate-limiting enzyme in the production of peptide messengers and may thus regulate the production of primary fatty-acid amides as well. The objective of this research is to elucidate the mechanisms that govern oleamide production in brain. Three specific aims are proposed for testing the hypothesis that PAM is the physiologic mediator of oleamide biosynthesis. Aim 1. Establish in a cell-free system that oleamide biosynthesis is dependent upon the actions of PAM. Cell-free models permit the direct investigation of fundamental reaction components. Subcellular fractions of N18TG2 mouse neuroblastoma cells, a line which expresses PAM and synthesizes oleamide, will be used to determine the effects of PAM inhibition on the biosynthesis of oleamide. Aim 2. Establish in cell culture that the induction of PAM during neuronal differentiation mediates an increase in oleamide production. Antisense RNA inhibition of PAM expression will be used to directly establish PAM as an integral component of the oleamide biosynthesis pathway in whole cells. Aim 3. Establish that the production of oleamide in vivo is dependent upon the action of PAM. Experiments conducted in rats will take into account the full biologic complexity of the mammalian organism. Direct measures of oleamide in brain and assessments of tissue activity for oleamide biosynthetic labeling will be used to demonstrate the extent to which inhibition of PAM in vivo impairs oleamide biosynthesis. These studies will define the physiologic role of PAM in mediating the biosynthesis of oleamide. Demonstrating that oleamide biosynthesis proceeds through PAM, or via an alternative pathway, will provide a basis for improving the diagnosis and treatment of sleep disorders.

Project Title: GERIATRIC DEPRESSION--NEUROBIOLOGY OF TREATMENT Principal Investigator & Institution: Reynolds, Charles F.; Professor; Psychiatry; University of Pittsburgh at Pittsburgh 350 Thackeray Hall Pittsburgh, Pa 15260 Timing: Fiscal Year 2002; Project Start 01-APR-1983; Project End 30-NOV-2003 Summary: In this revised competing renewal of MH37869-16, we propose a randomized, double-blind, placebo-controlled study to test a method for the rapid treatment of geriatric major depression and for probing treatment response variability. We hypothesize that therapeutic sleep deprivation (TSD) will accelerate response to paroxetine (PX), as compared with TSD (+ placebo) or with PX alone. In open pilot studies, we have observed a rapid response rate of 69 percent (9/13 subjects), with Hamilton depression ratings of 10 or less by 14 days, in elderly depressed patients treated with the combination of TSD (one night) and paroxetine (20 mg QHS). By contrast, in other studies of bereavement- related or recurrent major depression, we have observed rapid response rates to placebo of 15 percent, to nortriptyline of 25-32 percent, and to paroxetine alone of 26 percent, suggesting that the use of combined (TSD + medication) may double or triple the rate of rapid response as compared with placebo or drug monotherapy, respectively. With respect to treatment response variability in geriatric major depression, we hypothesize that metabolic activity in cortical areas (prefrontal cortex and ventral anterior cingulate gyrus) will decrease to normal levels in patients showing an antidepressant response to TSD and will remain decreased after recovery sleep in patients responding rapidly to antidepressant treatment. (Data from non-depressed control subjects will be collected for comparison.) By contrast, we predict
24
Sleep Deprivation
that glucose metabolism will remain elevated in non-responders and unchanged in nonresponders who may be hypometabolic at baseline. Our pilot data show a reduction in cingulate metabolism after TSD in patients but not controls; the reduction persists after successful treatment with paroxetine. We will recruit 108 elderly depressed outpatients with current major depression into a 14-day randomized, placebo-controlled, doubleblind, parallel-group study of TSD + PX, TSD + Placebo, and PX without TSD. All subjects will have pre-treatment MRI scans and twenty of 36 subjects in each treatment condition will also participate in PET studies of treatment response variability, together with 20 normal elderly control subjects. The percentage of patients meeting criteria for rapid response after 14 days of treatment in each of the three conditions will be contrasted in the intent-to-treat sample using contingency table analysis. Measures of subject expectancy, vascular risk factors, cerebral atrophy and white-matter hyperintensity, and cognitive status will be used as covariates in survival analyses of treatment response variability. Correlational analyses will be used to determine the association between changes in depression severity and alterations in regional glucose metabolic rates. Thus, this study aims to develop strategies to accelerate treatment response in geriatric major depression, to improve the early discrimination of nonresponders, to model the functional neuroanatomy of treatment response variability, and ultimately to reduce heterogeneity of treatment response in geriatric depression.

Principal Investigator & Institution: Howland, Jonathan; Professor and Chair; Social and Behavioral Sciences; Boston University Medical Campus 715 Albany St, 560 Boston, Ma 02118 Timing: Fiscal Year 2002; Project Start 01-JAN-1999; Project End 31-JUL-2005 Summary: (provided by applicant): This competing continuation application follows up on our studies of the residual effects of heavy drinking on next-day occupational performance. These effects may represent an important, but relatively unexplored, source of injury and error in the workplace. Several studies, including our own, have indicated that even when blood alcohol concentration (BAGs) is at or near zero, occupational impairment can occur the morning after heavy drinking. These effects have been shown for driving, simulated aircraft piloting, and performance of industrial tasks. Our study proposes to increase understanding of residual effects of heavy drinking by addressing several questions. We will provide further documentation regarding these effects. We will test several hypotheses regarding the mechanism by which heavy drinking affects next-day performance. Using a placebo-controlled randomized trial, we will dose participants with placebo or with a high or low congener alcoholic beverage (to a level of 0.10 g% BAC) the night before they perform exercises on an occupational training simulator. We will monitor participants' sleep to assess sleep disturbance; collect information on hangover symptoms the morning after dosing; and collect data on participants' family history of drinking problems. We will test the following hypotheses: (1) relative to placebo, heavy drinking will degrade next-day occupational performance, and this relationship will be mediated in full or in part by quality of sleep; (2) a high congener alcoholic beverage will affect performance to a greater degree than a low congener beverage and this relationship will be mediated by severity of hangover symptoms; and (3) the residual effects of heavy drinking on next-day occupational performance will be attenuated among participants positive for a family history of alcohol problems, relative to family-history-negative participants.

Project Title: HERITABILITY OF SLEEP HOMEOSTASIS Principal Investigator & Institution: Kuna, Samuel T.; Associate Professor of Medicine; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2003; Project Start 15-SEP-2003; Project End 31-AUG-2008 Summary: Excessive daytime sleepiness is a prevalent problem in our society associated with an increased risk of vehicular crashes and industrial accidents. Sleepiness is, in part, determined by fundamental biology relating to sleep homeostasis, i.e., the rate of accumulation of the pressure for sleep during wakefulness. A differential susceptibility to sleep deprivation is reported in normal subjects with large intra-individual differences in the degree of functional impairment produced by the same duration of sleep. Genetics are likely to play an important role in sleep homeostasis as shown by recent studies in inbred mouse strains, but whether genetics plays any role in humans and, if so, the magnitude of this role, is unknown. This proposal is based on the hypothesis that sleep homeostasis is a heritable trait in humans. Given the complexity of phenotyping to study sleep homeostasis, we propose that studying differences in the variances of the phenotype between monozygotic and dizygotic twins is the optimal approach to estimate heritability of sleep homeostasis. We will assess sleep homeostasis in 80 pairs of monozygotic and 80 pairs of dizygotic twins by quantifying the increase in delta power during recovery sleep following sleep deprivation and the increase in theta power during the period of prolonged wakefulness. Subjects will be recruited using the PennTwins Cohort, a population-based cohort of about 1,800 twin pairs. If heritability of sleep homeostasis is shown, this EEG-based phenotyping strategy could not be easily applied to the larger scale population studies that will be required to assess underlying genetic variants. Thus, part of our overall strategy is to evaluate, and potentially validate, other approaches to phenotyping that are less physiologically rigorous but are more easily applied to a larger number of subjects. Therefore, as a subsidiary goal, we will also estimate heritability of performance lapses during prolonged wakefulness as a surrogate method to assess sleep homeostasis. We will particularly determine whether the differences in the measures based on our physiological intensive phenotypes between pairs of dizygotic twins are reflected in differences in this phenotyping approach that is simpler to perform. Such a result would indicate that this simpler method could be used in larger scale population studies, and will be part of future strategies to elucidate genetic variants determining sleepiness.

Project Title: HOMEOSTATIC REGULATION OF SLEEP IN AGING Principal Investigator & Institution: Shiromani, Priyattam J.; Associate Professor; Psychiatry; Harvard University (Medical School) Medical School Campus Boston, Ma 02115 Timing: Fiscal Year 2002; Project Start 01-SEP-1998; Project End 31-AUG-2004 Summary: Sleep and wakefulness are regulated for the most part by circadian and homeostatic processes. The homeostatic process is more powerful and can override circadian influences. The nature of the homeostatic process is unknown, but might be molecular in nature. Recent studies with the immediate-early gene, c-fos, have shown that this gene is expressed differentially in discrete brain regions in response to sleep
26
Sleep Deprivation
and wakefulness. These findings have led to the hypothesis that c-fos might be representative of a molecular cascade that transduces a signal involving sleep. If this cascade is compromised, as with the application of c-fos antisense (which blocks new cFos protein synthesis), or in animals lacking the c-fos gene (null c-fos), then there should be less sleep. Our recent findings support this hypothesis. The proposed studies will examine whether the diminished sleep in aging might, in part, result from a decline in cfos to AP-1 binding. Four specific aims will directly test this hypothesis. Specific aim 1 will test the hypothesis that old rats (24 months) show less sleep and slow wave activity (0.3-4.0 Hz) for a given amount of prior wakefulness compared to young rats (2 months). Rats will be kept awake (by gentle handling) for various time periods (0, 6, 12 hr) and then allowed recovery sleep. The investigators predict that young rats will have more sleep, including increased slow wave activity (0.3-4 Hz), compared to old rats. Specific aim 2 will test the hypothesis that old (24 months) rats have reduced c-Fos and AP-1 binding in wake-active populations in the basal forebrain in response to wakefulness compared to young (2 months) rats. Rats will be kept awake as in Specific aim 1 and killed following 6, 12 hr of wakefulness. Immunohistochemistry and western blot assays will qualify c-fos levels. Gel-shift assays will examine the AP-1 complex in young vs. old rats. Specific aim 3 will test the hypothesis that old rats demonstrate a reduced response to adenosine in the basal forebrain compared to young rats. Adenosine will be dialyzed in the basal forebrain in young and old rats and the increase in sleep will be measured. The investigators predict that for the same dose of adenosine, older rats will show less sleep compared to young. Specific aim 4 will test the hypothesis that adenosine induces c-fos expression and resultant AP-1 binding in the basal forebrain. The investigators predict that the c-fos induction and AP-1 binding are much stronger in young versus old rats. Their preliminary results indicate that somnogens such as adenosine induce c-Fos (measured using immunohistochemistry and on tissue slices, and via western blot analysis of basal forebrain tissue homogenate) and AP-1.

Project Title: HYPOCRETIN RELEASE IN DISEASE STATES AND BEHAVIOR Principal Investigator & Institution: Siegel, Jerome M.; Professor; None; University of California Los Angeles 10920 Wilshire Blvd., Suite 1200 Los Angeles, Ca 90024 Timing: Fiscal Year 2002; Project Start 01-AUG-2001; Project End 31-JUL-2005 Summary: Recent work in our laboratory has indicated that a degenerative loss of hypocretin (orexin) neurons underlies most cases of human narcolepsy. Several chronic diseases have symptomatic similarities to narcolepsy. This suggests that they may share abnormalities in the operation of the hypocretin (Hcrt) system. For example, patients with unipolar depression and schizophrenia exhibit REM sleep at sleep onset, one of the defining characteristics of narcolepsy. Nighttime sleep is frequently disrupted in both disorders, as in narcolepsy. The age of onset of both of these disorders is similar to that of narcolepsy. Many patients with schizophrenia have hallucinations resembling the hypnagogic hallucinations of narcolepsy. Alzheimer's disease, like narcolepsy, is characterized by daytime sleepiness and nighttime sleep disruption. This "sundowning" and related hallucinatory mentation is the most frequent cause of institutionalization. We have developed a far more sensitive assay for Hcrt than that used in prior published studies and have access to a large number of cerebrospinal fluid (CSF) samples from these three groups of patients and suitable controls. We will determine if low Hcrt levels are unique to narcolepsy or if they are present in one or more of these other disorders. We will determine if an Hcrt blood test can be developed to detect narcolepsy. Such a test would have an enormous impact upon the diagnosis and treatment of sleep

disorders and on sleep research in general. We will compare blood Hcrt levels in narcoleptics, sleep apneics, REM sleep behavior disorder patients and controls. In parallel animal studies, we will determine the effect of behavior, including motor activity, feeding and short term sleep deprivation upon CSF Hcrt levels. Finally, we will use in vivo microdialysis to determine the pattern of Hcrt release in locus coeruleus, hypothalamus and ventrolateral preoptic area across the sleep wake cycle. We will contrast release patterns in active vs. quiet waking and REM vs. nonREM sleep. These studies will help define the role of this newly identified neurotransmitter system in relation to motor behavior, the sleep wake cycle and in human disease.

AND
THE
RESTLESS
LEGS
Principal Investigator & Institution: Allen, Richard P.; Assistant Professor; Neurology; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2003; Project Start 01-JUN-2003; Project End 31-MAY-2005 Summary: (provided by applicant): Restless Legs Syndrome (RLS) is a common sensorymotor disorders whose symptoms predominant at night and often lead to significant sleep loss and changes in one's quality of life. Rest and transiting between sleep and wake exacerbates RLS symptoms. Accordingly, alerting activities reduce while soporific ones exacerbate the symptoms. Sedating medications such as benzodiazepines, however, do not appear to exacerbate the disorder. RLS when even moderately severe profoundly disturbs sleep, reducing sleep times to 5-6 hours or less. Patients report some daytime problems with alertness and cognitive clarity but despite this reduction in sleep times untreated patients do not describe profound episodes of sleepiness that occur for normal subjects maintained on such restricted sleep schedules. There is apparently some alerting mechanism partially compensating for the sleep loss. Our recent work has found that nocturnal CSF values of hypocretin/orexin (Hcrt) are elevated in RLS patients not currently on treatment. Hcrt is almost absent in narcoleptics and serves to maintain wakefulness operating at least in part through the stimulating aspects of the histamine system. Several RLS patients on treatment with dopamine agents report some problems with sleepiness they had not previously experienced and several also report marked exacerbation of RLS symptoms by sedating anti-histamines. We have proposed that the Hcrt and histamine system activation reduces RLS symptoms for some RLS patients. DA treatment may reduce the activating benefit from this system leaving the patient vulnerable to sleepiness but also to further exacerbation of the symptoms by further reduction in this system by an anti-histamine medication. Thus, in this model, nocturnal Hcrt levels will be less for DA treated patients and antihistamine challenge provides a test discriminating those patients who have this aspect of RLS, identified in our prior work as those with the familial early-onset form of RLS. The anti-histamine challenge may therefore provide a new technique for discriminating types of RLS, possibly aiding in the diagnosis of RLS and opening up a new area of RLS research. The approach may also be extended to other DA related conditions involving sleepiness with DA treatment. This project seeks to determine if the nocturnal CSF hypocretin of RLS patients is lower when on DA treatment and to explore the development and evaluation of anti-histamine challenge for testing RLS patients.

Project Title: IMPACT OF SLEEP ON FEEDING AND THE METABOLIC SYNDROME Principal Investigator & Institution: Bass, Joseph T.; Evanston Northwestern Healthcare Evanston, Il 60201 Timing: Fiscal Year 2003; Project Start 30-SEP-2003; Project End 31-JUL-2007 Summary: (provided by applicant): Over the past two decades, an increased prevalence of sleep deprivation in the US has become a major public health challenge. Sleep deprivation been implicated in the epidemic of the metabolic syndrome, a condition characterized by insulin resistance, hyperlipidemia, cardiovascular disease and hypertension. Presently, 30% of the US population is overweight or obese and diabetes affects nearly 17% of persons over the age of 65. Recent clinical research indicates that sleep deprivation may pose a risk for the development of diabetes and the metabolic syndrome, however the underlying physiological and pathophysiological basis for the connection between sleep and metabolic homeostasis remains incompletely understood. This application proposes to exploit a novel experimental model of acute and chronic partial sleep deprivation in order to dissect the link between sleep loss and the metabolic syndrome. Already, we have found that chronic partial sleep loss in our animal model reproduces features of the metabolic syndrome including changes in hypothalamo-adrenal axis, decreased leptin and increased fatty acids. We have also made exciting discovery that suggest a role for alterations in the biological clock and clock regulated metabolic pathways that may lead to the metabolic syndrome. We now propose to apply the model we have developed together with molecular genetic tools to investigate the basic mechanisms that link sleep, circadian rhythms, food intake and energy homeostasis. Insight gained from these studies will provide new strategies to prevent metabolic complications associated with sleep deprivation and uncover novel metabolic targets for treatment of obesity and its co-morbidities.

Project Title: IMPACTS OF ALCOHOL / FATIGUE ON PARAMEDIC SKILLS Principal Investigator & Institution: Becker, Les R.; Pacific Institute for Res and Evaluation Calverton, Md 207053102 Timing: Fiscal Year 2001; Project Start 30-SEP-2001; Project End 30-JUN-2004 Summary: (Verbatim from application) A. Specific Aims Among employees in safety sensitive occupations, the two most prevalent forms of performance deficits are fatigue and alcohol related impairments, whether intoxication or hangover. The proposed research seeks to determine whether routine levels of fatigue and alcohol hangover among certified practicing Emergency Medical Technician-Paramedics (EMT-Ps) can be found to impair judgment and/or performance in such a way that patients who are reliant on the medical resuscitation and stabilization skills of EMT-Ps can be placed at unacceptable risk as a consequence of these impairments. There are currently no national standards for regulating these types of impairments for EMT-Ps, nor have the consequences of such impairments ever been systematically studied. The proposed study is important because EMT-Ps are society's front-line prehospital providers of emergency medical care, bringing Advanced Cardiac Life Support (ACLS) into America's homes and businesses. We will seek to validate a methodology and provide pilot information about specific areas of performance deficit among EMT-Ps. We will assess whether an instrumented manikin-simulator integrated with personal computerbased ACLS software can serve as a sensitive indicator, of performance impairment among licensed EMT- Ps. Depending on the findings, the results could serve to: temper

concerns that typical levels of fatigue and alcohol hangover raise patient risk, warrant mounting a more comprehensive evaluation of these relationships, and/or initiate policy action that will lower risks if risks are identified. Specifically, this project aims to: o Assess EMT-P performance deficits on standard cognitive and psychomotor tasks known to be sensitive to fatigue from partial sleep deprivation as well as low blood alcohol concentration (BAC), or alcohol hangover. o Validate the sensitivity of a rescue skill-specific programmable instrumented manikin-simulator with assessment protocols known to be sensitive to fatigue and hangover, and determine the extent to which the simulation can detect areas of task-relevant impairment among EMT-Ps when they are fatigued toward the end of typically long work shifts of 24 hours, and when they are coming onto a shift following moderate alcohol use that produces hangover symptoms 6 or more hours later. o Communicate preliminary findings to the emergency medical research community and to the state and national licensing boards authorized to set policy for EMT-Ps, emergency nurses, and emergency physicians.

Project Title: IMPORTANCE OF SLEEP & GENOTYPE IN DRUG ABUSE STUDIES Principal Investigator & Institution: Dugovic, Christine; None; Northwestern University Office of Sponsored Research Chicago, Il 60611 Timing: Fiscal Year 2002; Project Start 30-SEP-2001; Project End 31-AUG-2004 Summary: (provided by applicant): It has been well established that both genetic background and the environment can have pronounced effects on how mice respond to drugs of abuse, including both psychostimulants and the opiates. In particular, different strains of mice respond differentially to drug treatment, and acut7e sleep deprivation alters the response to a number of drugs of abuse. However, essentially nothing is known about how the genetic background affects the response to drugs of abuse in animals with disrupted sleep. Examining the effects of sleep disruption on the response to drugs of abuse in mice with different genetic backgrounds is particularly important since one of the hallmarks of substance abuse in humans is disrupted sleep. Poor sleep, whether due to genetic or environmental causes, may in itself predispose one to abuse and drug addiction. One of the overall objectives of the proposed studies is to determine if the effects of acute sleep deprivation on the response to drugs of abuse in mice is dependent on genetic background. Since very little is known about the effects of chronic sleep loss on the response to drugs of abuse, a second overall objective will address this question and determine if the genetic background influences the effects of chronic partial sleep deprivation on the response to drugs of abuse. Six different strains of mice will be used to test hypotheses. that genetic differences in either sensitivity or sensitization of the locomotor response to either cocaine or morphine are affected by either acute or chronic partial sleep deprivation. The completion of the proposed studies is expected to not only lead to a better understanding of how genetic differences predispose mice to be more or less responsive to cocaine and/or morphine under both baseline and sleep deprivation conditions, but also will provide new insights for optimizing the genetic animal models to be used for ultimately elucidating the genetic, neurochemical and biochemical mechanisms underlying the actions of drugs of abuse. The use of these genetic animal models is expected to lead to new genetic and pharmacological strategies for the treatment of drug abuse and addiction.

Principal Investigator & Institution: Van Dongen, Hans P.; Research Assistant Professor; Psychiatry; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2002; Project Start 01-APR-2002; Project End 31-MAR-2006 Summary: (provided by applicant): The magnitude of neurobehavioral performance failure during sleep deprivation varies widely among individuals, and there are marked inter-individual differences in the structure of subsequent recovery sleep as well. Using a repeated total sleep deprivation (TSD) paradigm, the proposed project seeks to quantify the trait component of inter-individual differences in the response to sleep loss. In order to examine the malleability of the trait component, the magnitude of the trait component will also be compared with the magnitude of the response to a change in workload state. In addition, potential predictors of individual responses to sleep loss will be identified. A total of n=39 subjects will be exposed, on three consecutive occasions, to 36 hours of controlled TSD in a laboratory. Each 36-hour TSD will be followed by two 12-hour recovery sleep opportunities. Throughout the experiment, waking neurobehavioral performance will be monitored every two hours at fixed times by means of standardized behavioral tests, while baseline and recovery sleep will be studied with polysomnography (PSG) and electroencephalogram (EEG) powerspectral analysis. For each subject, two of the three TSD periods will involve moderate workload, while the other TSD period will have high (i.e. double-duration) workload, in randomized counterbalanced order. The investigation has five specific aims: (1) Quantify the magnitude and importance of inter-individual variability in neurobehavioral performance failure during TSD and the structure of subsequent recovery sleep; (2) Quantify the extent to which neurobehavioral performance failure during TSD involves a trait response and/or a state response to workload; (3) Quantify the extent to which the structure of recovery sleep following TSD involves a trait response and/or a state response to prior workload; (4) Explore the relationship between individuals' magnitude of neurobehavioral performance failure during TSD and the structure of their subsequent recovery sleep; and (5) Identify predictors of individuals' magnitude of neurobehavioral performance failure during TSD and the structure of their subsequent recovery sleep, by examining six predictor domains: baseline neurobehavioral performance, baseline sleep architecture, circadian rhythmicity, physical characteristics, psychological parameters, and demographic statistics. The results of this investigation will fill a critical gap in our understanding of inter-individual differences in the response to sleep loss, and the factors that determine these differences. The research will be relevant for the understanding, remediation and prevention of the potentially serious effects of sleep deprivation in the millions of individuals who are occasionally or routinely exposed to sleep loss due to medical condition, occupation or lifestyle.

hypothesis; administration of exogenous IL-1-beta enhances non-rapid eye movement sleep (NREMS); inhibition of IL-1-beta inhibits spontaneous NREMS and NREMS induced by sleep deprivation; IL-1-beta mRNA has a diurnal rhythm in brain and increases after sleep deprivation. In Specific Aim #1, the investigators will test the specific hypothesis that the IL-1 type I receptor (IL-1RI) is necessary for IL-1-mediated changes in sleep regulation. They will use a knockout mouse lacking this receptor; preliminary data suggest that these mice sleep less than strain controls. Further, they do not respond to IL-1-beta. In Specific Aim #2 the investigators will test the hypothesis that the IL-1-beta and tumor necrosis factor-alpha (TNF) systems act in concert to regulate NREMS and are part of a larger functional gene group involved in sleep regulation. For these experiments, the investigators will use the IL--1RI knockout mouse and double knockout mouse which lacks both the IL-1RI and the TNF55-kD receptor. Specific Aim #3 tests the hypothesis that somnogenic stimuli will induce changes in specific areas of brain in the levels of one or more of the members of the IL-1 receptor antagonist will be measured using reverse transcriptase polymerase chain reaction, Northern blot analyses and RNASE protection assays. The effects of various somnogens (sleep deprivation, muramyl dipeptide and acute mild increases in ambient temperature) on the levels and distribution of these mRNAs in brain will be determined. Anticipated results will help our understanding of how the brain is organized to produce sleep. They will also help our understanding of the cellular and molecular mechanisms of sleep regulation. Knowledge of such mechanisms is likely to be a necessary step toward our understanding of sleep function. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: LIGHT VISOR FOR TREATING JET LAG: CONTROLLED FIELD TRIAL Principal Investigator & Institution: Boulos, Ziad; Research Scientist; Bio-Brite, Inc. 4340 East West Hiwy, Ste 401 Bethesda, Md 20814 Timing: Fiscal Year 2003; Project Start 30-SEP-2000; Project End 31-JUL-2005 Summary: (provided by applicant): Jet lag is a syndrome of behavioral, cognitive, and physical symptoms that result when travelers are exposed to a sudden shift of the daynight cycle. These symptoms impact on alertness and performance of airline and military personnel and the safety of the traveling public. They may also exacerbate medical and psychiatric illness, and frequent flyers may face increased risk of disease. The long-term objective of this project is to develop a practical and effective treatment for jet lag using the Bio-Brite Light Visor to phase-shift circadian rhythms. Phase 1 demonstrated that the visor was effective in phase-shifting human circadian rhythms and accelerating circadian reentrainment following a westward flight across 6 time zones, but the effect on reentrainment rate was not sufficient to improve sleep, performance, or subjective measures of jet lag. Phase 2 is designed to improve the efficacy of the light treatment by implementing changes to the visor itself and to the light treatment schedule. These changes will be tested first in laboratory experiments, and then in a field study with both eastward and westward flights across 6 time zones (New York-Zurich-New York). Bright light (3000 lux) or dim red light (control) treatment will be scheduled for 3 h on the three mornings immediately preceding the eastward flight, and on the three evenings immediately following the westward flight. Subjects will also be required to avoid exposure to bright light at specific times after the eastward flight. Circadian reentrainment rates will be examined, using salivary dim light melatonin onset (DLMO) as phase reference. Other jet lag indices will include sleep quality and duration, determined from wrist actigraphic recordings and from scores on

a subjective sleep quality questionnaire, performance on a psychomotor vigilance task, and subjective assessments of mood, daytime sleepiness, and other jet lag symptoms. Phase 2 will also include a data analysis component aimed at generating light exposure and avoidance schedules keyed to individual chronotype and to travel origin and destination.

Project Title: LOCUS COERULEUS ACTIVITY DURING SLEEP DEPRIVATION Principal Investigator & Institution: Doran, Scott M.; Psychiatry; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2003; Project Start 01-SEP-2003; Project End 31-AUG-2004 Summary: (provided by applicant): The project proposed in this application is designed to test how 43 hours sleep deprivation (SD) alters performance and locus coeruleus (LC) activity in rhesus monkeys engaged in a task requiring sustained and selective attention. The first goal is to validate the rhesus monkey as an animal model to explore the neurophysiology of cognition during SD. The LC is the primary source of cerebral norepinephrine and its activity is known to contribute both to attentional processes and arousal-state control. Most theoretical accounts for the impact of SD on behavior claim (or imply) that changes in LC and norepinephrine actively modulate the arousal-limited cognitive resources necessary for performance. This project will provide the first empirical test of that assumption with a design that samples performance and LC activity every 3 hours, sufficient temporal sampling to track the influence of both homeostatic and circadian pressures on performance. Human performance during SD shows increases in reaction time and error rate that is modulated by circadian phase. Sleep deprived human performance becomes highly variable, revealing both nonresponsiveness and moments of near-normal performance. To test if SD results in degraded or compensatory LC activity, baseline and task-related LC neuronal firing will be evaluated as a function of time awake during 43 hours without sleep. The ability for exogenous auditory stimulation to activate the LC and/or improve performance as time awake increases will also be tested. This project assimilates validated methods of cognitive testing in primates, electrophysiologic LC recording, and monkey sleep deprivation in an experiment designed to provide original data measuring how SD alters brain activity critical for cognition.

Among the most prominent brain changes are reductions in total sleep and a huge decline in the amplitude and abundance of the delta EEG of NREM sleep. Other brain changes in adolescence include synaptic elimination and a reduction in cortical metabolic rate. Neurodevelopmental models posit that schizophrenia may be caused or unmasked by abnormalities in these maturational processes. Daytime sleepiness emerges in adolescence, impacting mood and school performance. However, a specific withinsubjectstudy of the relation of daytime sleepiness to quantitative changes in sleep EEG

waveforms has not been reported. There are other major gaps in our knowledge. We do not know the within-subject rates of change in the amplitude and incidence of EEG waves in delta and other frequencies, whether 'spurts' in delta decline normally occur, the shapes of the age curves, their relation to age vs. pubertal stage, and the extent of individual and gender differences. Our research aims to fill these gaps by studying sleep longitudinally in 2 age cohorts (ages 9-13 and 12-16 years) during the period of most rapid change. Baseline and extended sleep will be studied twice/yr for 4 years. EEG waveforms will be quantified with FFT-spectral and period amplitude analyses (the 2 most widely used computer methods) and with visual sleep stage scoring. Sleepiness will be assessed with the MSLT and behavioral ratings and mood will be systematically evaluated at each time point. The proposed research will help fill major gaps in our knowledge of one of the most pronounced maturational changes of the human brain, It will also test specific hypotheses regarding the : correlates of these changes. The data we acquire could shed light on concomitant brain changes, leading to the identification of new biological relationships. Our studies will also provide benchmark data for neurodevelopmental studies in psychiatrically ill adolescents and 'at-risk' population.

Principal Investigator & Institution: Ricaurte, George A.; Associate Professor; Neurology and Neurosurgery; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2002; Project Start 01-AUG-1989; Project End 31-MAR-2007 Summary: (Adapted from applicant's abstract): The 3,4-Methylenedioxymethamphetamine (MDMA, 'Ecstasy'') is an illicit amphetamine analog that is increasing in popularity in the United States and abroad. In addition to its abuse potential, MDMA is well documented as a potent and selective serotonin neurotoxin in animals. A growing body of evidence indicates that human MDMA users are also susceptible to MDMA-induced serotonin neurotoxicity. Although functional sequelae of MDMA-induced serotonin neurotoxicity appear to be subtle, a number of laboratories have documented abnormalities in memory and other cognitive processes in MDMA users compared to matched control groups. Since it is known that neurons involved in cognitive processes decrease with aging (e.g., catecholaminergic and cholinergic neurons), there is concern that MDMA users may be at risk for developing clinically significant cognitive abnormalities as they age. The overall goal of this revised competing renewal application is to determine if pharmacological and physiological challenges that are intended to simulate selected features of aging (i.e., loss of catecholaminergic/cholinergic function and/or sleep continuity) can be used to better detect and characterize possible detrimental effects of MDMA neurotoxicity upon cognitive processes in humans. The hypothesis to be tested is that MDMA-induced brain serotonergic injury will render MDMA users more susceptible to cognitive deficits associated with disruption of catecholaminergic and cholinergic neurotransmission and sleep continuity. The Specific Aims of the project are: 1) To determine whether or not MDMA users, compared to matched controls, are more susceptible to the disruptive effects of the catecholamine synthesis inhibitor, alpha-methyl-para-tyrosine (AMPE), on cognitive processes; V To determine if MDMA users, compared to matched controls, are more susceptible to the disruptive effects of the cholinergic antagonist, scopolamine, on cognitive processes; 3) To determine whether or not sleep deprivation, a naturalistic physiological challenge that is known to lead to deficits in cognition (and which is common in elderly populations), produces more profound effects on cognition in
34

MDMA users compared to matched controls; and 4) To determine whether there is a relationship between cognitive deficits in MDMA users and the level of CSF 5hydroxyindoleacetic acid, a validated measure of MDMA-induced brain serotonin neurotoxicity. The proposed studies hold promise for improving our understanding of the functional consequences of MDMA-induced serotonin neurotoxicity in humans, and should advance knowledge regarding the role of brain serotonin and other neurotransmitter systems in cognition.

Project Title: MECHANISMS OF DIFFERENTIAL SLEEPINESS IN SLEEP APNEA Principal Investigator & Institution: Weaver, Terri E.; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2003; Project Start 15-SEP-2003; Project End 31-AUG-2008 Summary: The purpose of this proposal is to explore potential operating mechanisms in the differential sleepiness observed in patients with equivalent degrees of obstructive sleep apnea (OSA). Within a given level of disease severity, i.e., number of respiratory disturbances during sleep, inter-individual differences, or differential vulnerability to sleepiness, have been noted in both subjectively measured and objectively measured daytime sleepiness. The reason for this phenomenon remains unclear. Critical to the management of patients with OSA is the understanding of mechanisms associated with the development of daytime sleepiness. We hypothesize that the variance in daytime sleepiness (EDS)will have a substantial trait component in addition to state-related factors among patients with equivalent levels of OSA severity. To systematically identify sources of EDS variance in sleepy and non-sleepy OSA patients, the specific aims of this study will determine: 1) state-specific variance related to sleep duration, obesity and fat distribution, specific comorbidities, and use of certain medications; 2) mis-estimation of severity of sleep disordered breathing from night-to-night variability in respiratory disturbances; 3) underlying trait associated with differential vulnerability to the sleepiness-producing effects of OSA. Using actigraphy and diaries to document sleep duration and both objective and subjective evaluations of sleepiness, Protocol A will classify 260 newly diagnosed OSA subjects as sleepy vs. non-sleepy and will document inter-individual differences in sleepiness among patients with similar disease severity caused by sleep history, obesity and fat distribution, specific comorbidities, and use of certain medications. Controlling for the variance identified in Protocol A, Protocol B will determine the degree to which inter-individual differences in sleepiness in 180 untreated OSA subjects with similar disease severity is a consequence of night-to-night variability in the occurrence of sleep disordered breathing documented by 7 consecutive nights of home sleep studies. Such night-to-night variability would reduce the reliability of single night determinations of apnea severity. Finally, in Protocol C we will determine if inter-individual differences in sleepiness remain after accounting for the variance explained by the clinical factors identified in Protocol A and the variance explained by mis-estimation of severity of sleep disordered breathing documented in Protocol B. In Protocol C, 60 patients (30 sleepy, 30 non-sleepy) will be matched on initial apnea severity and a set of a priori sleepiness factors will undergo 38 hrs of sleep deprivation in a laboratory to determine the existence of an underlying trait for daytime sleepiness.

Project Title: MECHANISMS UNDERLYING THE COGNITIVE FUNCTION OF SLEEP Principal Investigator & Institution: Datta, Subimal; Professor; Psychiatry; Boston University Medical Campus 715 Albany St, 560 Boston, Ma 02118 Timing: Fiscal Year 2002; Project Start 01-DEC-2000; Project End 30-JUN-2005 Summary: The long-term objective of this application is to identify the cellular mechanisms underlying the cognitive function of sleep. Specifically, the goal is to investigate what role brainstem rapid eye movement (REM) sleep generating structures play in sleep-dependent learning in the rat. Clarifying the mechanisms of sleepdependent learning and memory will move the field of cognitive research closer to the development of effective treatments for cognitive deficiencies associated with sleep disorders. The central hypothesis of this proposal is that activation of phasic P-wave generating cells in the dorsal part of the nucleus subcoeruleus is critical for sleepdependent learning and memory processing. From this hypothesis, four testable questions have been generated: 1. After learning task training, does supplementary activation of the P-wave generator enhance information processing efficiency, resulting in improved learning? Immediately after a session of two-way active avoidance test trials, the P-wave generator will be directly activated by a discrete microinjection of carbachol. The effect of this supplementary activation will be examined in retest trials after a six hour period of undisturbed sleep. 2. Does the activation of the P-wave generator during REM sleep enhance a physiological process of memorization which naturally occurs during post-learning sleep? The procedure for testing this question is the same as that of question 1, except that these rats are REM sleep deprived for the six hour period between test and retest trials. 3. Does the elimination of cells in the P- wave generator attenuate learning abilities in post-sleep retest trials? P-wave generating cells will be directly eliminated by a discrete microinjection of kainic acid. The retest performance of these P-wave generating cell lesioned rats will be compared with that of the sham lesioned rats. 4. Is the increased density of P-waves during post-learning REM sleep due to the activation of P-wave generating cells? P-waves and single cell unitary activity of P-wave generating cells will be simultaneously recorded in freely moving rats after a session of learning trials. This proposal addresses at the mechanistic level, the general question, what is the function of sleep? and also promises to further sleepdependent cognitive research in the direction toward treatments for cognitive impairments associated with jet lag, shift work, sleep deprivation and brainstem degenerative disorders.

Project Title: MELATONIN RANDOMIZED TRIAL FOR INSOMNIA IN THE ELDERLY Principal Investigator & Institution: Gooneratne, Nalaka S.; Medicine; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2003; Project Start 22-SEP-2003; Project End 31-MAY-2007 Summary: (provided by applicant): Chronic insomnia affects up to 35% of the elderly. It can significantly impair quality of life and daytime functioning. Currently, most medical therapy for insomnia involves sedative-hypnotic agents that may lead to dependence, withdrawal side effects and reduced efficacy after extended periods of use. A growing body of work has suggested that melatonin, a neurohormone produced by the pineal gland and regulated by the suprachiasmatic nucleus, the primary circadian pacemaker, may play a role in mediating insomnia. Ongoing research at the University of
36
Sleep Deprivation
Pennsylvania in 180 elderly insomnia patients has found statistically significant evidence of a decreased sleep efficiency in low melatonin insomniacs. Thus, melatonin production is impaired in a subgroup of elderly insomnia patients and this may contribute to their insomnia. However, melatonin treatment trials in elderly insomniacs have been equivocal. These studies have had serious methodologic limitations including inadequate sample size (Type II error), lack of objective measures of sleep or daytime functioning, and no placebo control arm. This has raised many questions such as whether melatonin deficiency is a marker of insomnia or, instead, a contributing factor and whether increased doses are needed to recreate the higher levels seen in the cerebrospinal fluid compartment. In addition, melatonin is widely used as an over-thecounter sleeping aid with litre true insight into its effectiveness/safety, especially in older adults. To address the primary hypothesis that melatonin can treat insomnia in melatonin-deficient elderly, the principal investigator proposes conducting a large randomized, double-blind clinical trial comparing low dose melatonin (0.4 mg), high dose melatonin (4.0 mg) and placebo in a well-defined group of elderly insomniacs with low melatonin levels (189 total subjects). The specific aims are to 1) evaluate the effectiveness of melatonin and 2) assess the daytime consequences and safety of melatonin treatment in this population. Intention-to-treat analysis will compare low dose melatonin, high dose melatonin, and placebo on objective and subjective parameters of sleep and daytime function. This protocol will extend well beyond the research done to date by rigorously testing the role of targeted melatonin replacement therapy as an effective treatment for insomnia in the elderly and by evaluating the safety profile of melatonin with a particular focus on daytime functioning.

Project Title: MEMORY CONSOLIDATION AND SLEEP Principal Investigator & Institution: Hellman, Kevin M.; Neurology; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-AUG-2003 Summary: The goal of our research is to identify the neural mechanisms by which sleep enables memory consolidation. Sleep regulates many physiological processes and impairment of sleep is seen in many diseases that impair memory: Alzheimer's disease, Parkinson's disease, depression and sleep apnea. Many studies have demonstrated sleep deprivation following learning will impair memory. We will use behavioral experiments, electrophysiology and molecular biology to deduce the neural mechanisms responsible for sleep alterations after fear conditioning. We will use fear conditioning as a learning paradigm to because it is a single-trial task with a defined time course of memory consolidation. After fear conditioning, we have discovered that mice have a period of increased arousal followed by increased sleep three hours following fear conditioning. We have also seen changes in thalamo-cortical (delta) and hippocampal (theta) oscillations associated with sleep. During the period of arousal there is a decrease is both delta and theta oscillations, but during the following 2 hour sleep period there is an increase in delta and theta oscillations. We believe these change in sleep activity are essential to memory consolidation because when we sleep deprive mice following fear conditioning long-term memory consolidation is impaired. In Specific Aim 1 we will identify changes in sleep after fear conditioning. In Specific Aim 2 we will identify alterations in gene transcription and protein synthesis during sleep after fear conditioning. In Specific Aim 3 we will examine the role of the cAMP/PKA/CREB signaling during sleep following fear conditioning in transgenic mice.

Principal Investigator & Institution: Smith, Gwenn S.; Associate Professor; Long Island Jewish Medical Center 270-05 76Th Ave New Hyde Park, Ny 11040 Timing: Fiscal Year 2002; Project Start 01-AUG-1998; Project End 31-JUL-2003 Summary: (Applicant's abstract): An important therapeutic issue in neuropsychiatric disease, particularly in geriatric patients, is the variability in treatment response and the inability to predict treatment outcome. Decreased monoaminergic responsiveness may be a potential neurobiologic mechanism underlying treatment resistance across several neuropsychiatric disorders. The overarching theme of the candidate's funded research in AD, schizophrenia and geriatric depression is that decreased monoaminergic responsiveness is related to treatment resistance. To evaluate monoaminergic function in vivo, the candidate has developed methods using Positron Emission Tomography (PET) imaging, radiotracers for neurotransmitter receptors and pharmacologic challenges. This application of PET methodology represents the most direct, noninvasive and quantitative method of measuring neurotransmitter activity in the living human brain. The PET studies performed thus far have consistently demonstrated substantial between subject variability in monoamine responsiveness in normal controls and in patients. Variability of monoamine responsiveness has been observed also in pharmacologic challenge studies using behavioral and neuroendocrine outcome measures. The goals of this Independent Scientist Award are to obtain training in methods complementary to brain imaging techniques that will enable the candidate to better interpret the variability in monoaminergic responsiveness observed in the PET data. The goals of the training experience are to incorporate genetic markers of monoamine receptor and transporter alleles and polysomnographic methods into her existing research program and to obtain training in the neuroanatomy of cholinergic and monoaminergic interactions and neuroimaging in affective disorders. The research plan is conducted within the framework of three funded studies to use PET to investigate 1) serotonin-dopamine interactions in schizophrenia; 2) cholinergic modulation of monoamine function in Alzheimer's Disease; and 3) the effects of sleep deprivation and antidepressant treatment on cerebral glucose metabolism in geriatric depression. These studies are designed to relate alterations in monoamine responsiveness to subsequent therapeutic response. The long term goal of the candidate's research is to understand the neurobiologic substrates of treatment resistance in neurodegenerative disorders and to use the genetic, polysomnographic and imaging data to predict the course of pharmacotherapy. The Independent Scientist Award will enable the candidate to firmly focus her research in the area of geriatric neuropsychiatry. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: NEURAL GENE EXPRESSION IN SLEEP DEPRIVATION AND RECOVERY Principal Investigator & Institution: Kilduff, Thomas S.; Senior Director; Sri International 333 Ravenswood Ave Menlo Park, Ca 94025 Timing: Fiscal Year 2003; Project Start 30-SEP-1997; Project End 30-JUN-2007 Summary: (provided by applicant): The function of sleep and the biochemical nature of the restorative process that occurs during sleep are among the great mysteries of neuroscience. Experimental observations confirm the common experience that sleep deprivation (SD) leads to sleepiness and that restricted sleep time imposes a sleep "debt" which ultimately must be "repaid" by sleep extension. The hypothesis that underlies our
38
Sleep Deprivation
studies is that the homeostatic sleep-related "Process S" is biochemical in nature and the sleep-dependent restorative process involves macromolecular synthesis that can be detected at the RNA level. Consistent with this idea, during the previous funding period we have identified several genes whose expression is increased during sleep after SD. In the current application, we propose to determine expression of these and other genes at multiple times during recovery sleep after SD. Recent studies have determined that, although the time constant for the decay of Process S (taud) is highly conserved, the time constant for the increase of Process S (taui; referred to as sleep "need") varies considerably among mouse strains. Therefore, we will compare the neural gene expression profile in three strains of mice that exhibit large differences in the buildup of sleep need to identify mRNAs whose expression may increase in parallel with sleep need. Building on the neural gene expression database that we have established in the current funding period, we will extend our microarray studies to pharmacologically induced sleep and compare the patterns of gene expression induced by clinically effective hypnotic agents to that observed during normal sleep. These experiments may determine whether a final common pathway for sleep induction can be identified. Last, building on a model of hypothalamic and preoptic area involvement in sleep regulation that has emerged over the last few years, we will test the hypothesis that clinically used hypnotics are effective in sleep induction through changing the functional activity of brain nuclei known to be sleep- or wake-active. These experiments should provide insights into the biochemical process occurring during wakefulness that predisposes to sleepiness as well as the restorative i process that occurs during sleep itself.

Project Title: NEUROBEHAVIORAL EFFECTS OF PARTIAL SLEEP DEPRIVATION Principal Investigator & Institution: Dinges, David F.; Professor; Psychiatry; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2002; Project Start 30-SEP-1995; Project End 31-DEC-2003 Summary: The role of sleep in maintaining healthy, optimal waking functions, is compromised by sleep loss from illness, aging, pain, depression, and life-style. The single most pervasive form of sleep loss experienced by millions of persons for either medical or lifestyle reasons is partial sleep deprivation (PSD). This project seeks to determine how waking neurobehavioral functions sensitive to sleepiness are affected by chronic PSD. A basic unresolved question is the amount and timing of chronic PSD at which alertness and waking function are compromised. This research is specifically aimed at establishing the nature and time course (across hours and days) of deficits engendered by chronic sleep restriction, and the extent to which they reflect an interaction between the homeostatic drive for sleep and the endogenous circadian pacemaker. The project involves the first systematic laboratory controlled experiments on the effects of 14 days of PSD on neurobehavioral and physiological functions. A randomized controlled trial will be performed in which three PSD dosages (4hr, 6 hr, 8 hr, per day) are placed at three different circadian phases (time-in-bed offset at 0330hr, 1130hr, 1930hr), thereby yielding nine conditions, each of which exposes a different range of the circadian cycle to waking neurobehavioral assessment. A total of 180 healthy adults will be studied (n=20 per condition) in the laboratory for 20 days each, during which time they will undergo 14 days of sleep restriction. Assessments will be made of key outcome variables including psychomotor vigilance lapses, cognitive functions, working memory, EEG alertness, subjective sleepiness, and mood. The results of this research will provide much-needed information on current issues of intense theoretical and applied concern including particular relevance to current public policy

Project Title: NEUROBIOLOGY OF SLEEP APNEA IN AGING Principal Investigator & Institution: Carley, David W.; Professor; Medicine; University of Illinois at Chicago 1737 West Polk Street Chicago, Il 60612 Timing: Fiscal Year 2002; Project Start 01-JUL-1999; Project End 30-JUN-2004 Summary: (Applicant's abstract): Sleep apnea syndrome affects at least 3 percent - 5 percent of the adult population in this country and available data suggest that significant morbidity and mortality result from this disorder. It is now well established that the prevalence of sleep-related apnea is dramatically elevated in the elderly with recent estimates ranging from 28 percent - 67 percent for elderly males and from 20 percent - 54 percent for elderly females. However, the mechanisms underlying the age related increase in apnea genesis remain poorly understood. This uncertainly stems in part from a paucity of appropriate animal models to study spontaneous apneas in all stages of sleep. Rapid eye movement (REM) sleep is associated with apneas, reductions in respiratory and upper airway motor outputs, and increased variability of respiration, heart rate and blood pressure. We present novel preliminary evidence suggesting that increased apnea expression with aging results from dysregulation of brainstem respiratory control systems by brainstem phasic events (BPE) in the elderly. Pontogeniculo-occipital (PGO) waves are a close marker of BPE and are closely associated with cardio- respiratory changes, including apnea. The overall goals of this proposal are to (i) investigate the neural mechanisms by which BPE influence apnea genesis, and (ii) establish the importance of these mechanisms to the age-related increase in apnea. To achieve these goals, we will combine descriptive and interventional human studies with invasive central nervous system measurements and manipulations in rats using a model of sleep-related respiratory instability which we have characterized. We will focus our attention on the pedunculopontine tegmental nucleus (PPT), the putative site of the burst generator responsible brainstem phasic events detectable as PGO waves. We will manipulate BPE expression in two directions: 1) we will augment expression by acoustic stimulation and sleep deprivation in man and rat and by microinjection of cholinergic agonists into PPT in the rat; and 2) we will reduce expression by electrolytic lesions of the PPT in the rat. These manipulations in old and young patients, controls, and rats will provide a comprehensive approach to define the mechanisms and importance of brainstem phasic event-induced respiratory instability in aging.

Project Title: NEUROCHEMICAL REGULATION OF CIRCADIAN TIMING Principal Investigator & Institution: Rea, Michael A.; Professor; Biology and Biochemistry; University of Houston 4800 Calhoun Rd Houston, Tx 77004 Timing: Fiscal Year 2002; Project Start 25-SEP-2001; Project End 31-AUG-2006 Summary: (provided by applicant): In mammals, the sleep and circadian systems are intimately coupled and mutually essential for the proper coordination of physiological processes and behavior. The circadian clock located in the suprachiasmatic nucleus (SCN) provides for the temporal organization of sleep by promoting alertness during periods of high homeostatic sleep drive. In turn, the circadian program of sleep organization is synchronized to environmental rhythms through periodic adjustments

Sleep Deprivation
of the phase and period of the circadian clock by ambient light. The neuroanatomical and neurophysiological mechanisms responsible for the imposition of circadian organization on the sleep process are only beginning to be understood. Furthermore, no mechanism has yet been described through which sleep-related processes might influence circadian timing. The current proposal seeks to delineate such a mechanism. The purine nucleoside, adenosine, has been implicated as a key component of the homeostatic sleep mechanism. Adenosine accumulates in the basal forebrain cholinergic area during sustained wakefulness, where it has been shown to promote sleep through an adenosine A1 receptor-dependent mechanism. Systemic administration of an adenosine A1 receptor agonist attenuates the magnitude of light-induced phase adjustments of the SCN circadian clock. We propose that adenosine provides information to the circadian clock regarding the state of fatigue of the organism, resulting in an altered response to light-induced phase adjustments. In the current proposal, we will test the hypothesis that increased adenosine production in the SCN region during sustained wakefulness attenuates light-induced adjustments in circadian phase by interacting with presynaptic A1 receptors located on RHT nerve terminals to reduce the release of glutamate. This work will reveal a novel and potentially important aspect of sleep and circadian regulation in mammals. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: NEUROCHEMICAL SUBSTRATES OF SLEEP HOMEOSTASIS Principal Investigator & Institution: Dorsey, Cynthia M.; Mc Lean Hospital (Belmont, Ma) Belmont, Ma 02478 Timing: Fiscal Year 2003; Project Start 15-SEP-2003; Project End 31-MAY-2007 Summary: (provided by applicant): Difficulty initiating/maintaining sleep afflicts up to 30% of the population, yet the neurochemical processes associated with sleep and sleep disturbances have not been clearly identified. A better understanding of EEG slow-wave activity and its role in recovery from sleep loss could be invaluable in elucidating the homeostatic sleep mechanism and shedding light on how to treat disturbed sleep. Further, sleep disturbances contribute to relapse to drug use and such efforts might help address this serious public health problem. The purpose of the study is to identify neurochemical markers of sleep mechanism in an intact and an impaired system, by evaluating changes in brain chemistry produced by disrupted sleep. In response to RFAHL-01-009, "Interrelationship between sleep and heart, lung, and blood diseases" we propose two experiments. In the first, polysomnography (PSG) and phosphorous magnetic resonance spectroscopic imaging (31P MRSI) will be collected at baseline, after sleep deprivation, and after recovery sleep in controls and in methadone-maintained subjects. Measures will be repeated at 1 and 3 months to determine if the effects persist. In the second experiment, PSG and 31P MRSI data will be collected from unmedicated cocaine-dependent and opiate-dependent subjects during acute withdrawal and at 1 and 3 months post withdrawal. As the abstinence profile for sleep disturbance differs in these groups (hypersomnia vs insomnia, respectively) this experiment will help delineate the conditions under which altered brain bioenergenics exist. 31P MRSI can be used to measure global and focal changes in high energy phosphate alpha-,gamma,beta-NTP (ATP). Our pilot data showed significant increases in beta-NTP and decreases in phospholipid catabolite production after recovery following sleep deprivation in control subjects. 31P MRS changes have been observed in chronic opiate-dependent individuals at baseline, but have not been evaluated during sleep. Chronic sleep disturbances have been reported in opiate abusers and methadone-maintained patients and the homeostatic sleep mechanisms may be impaired in chronic opiate abuse. We

41
hypothesize that methadone-maintained subjects will have decreased beta-NTP and will exhibit smaller slow wave sleep rebound and a more modest or no increase in beta-NTP after recovery. Further, the neurochemical response to sleep deprivation in these subjects will approach that of controls over time b-NTP will increase during cocaine withdrawal and decrease during opiate withdrawal, reflecting their differential effects on sleep during this time. Collectively, these studies may identify neurochemical markers for the recovery function of sleep, thus enhancing our understanding pf basic sleep mechanisms and potentially leading to new and improved treatments for sleep disturbances in both the substance-abusing and general population.

Project Title: NEUROENDOCRINE ABNORMALITIES INDUCED BY SLEEP DEPRIVATIO Principal Investigator & Institution: Everson, Carol A.; Associate Professor; Neurology; Medical College of Wisconsin Po Box26509 Milwaukee, Wi 532264801 Timing: Fiscal Year 2001; Project Start 01-JUL-1999; Project End 31-MAY-2004 Summary: (adapted from applicant's abstract): Sleep is a vital biological process necessary to maintain cognitive ability and physical health. Profound sleep disturbance/deprivation in humans is nearly always associated with disease, and sleep deprivation in patients is considered a high risk factor for mortality. In animal models of sleep deprivation, morbidity is associated with septicemia subsequent to a constellation of neuroendocrine changes, most notably hypothyroxinemia. Preliminary data have shown that neuroendocrine abnormalities extend to deficiencies in growth hormone (GH) and prolactin (PRL), and have the potential to explain most of the pathology induced by sleep deprivation. There is strong evidence that the neuroendocrine changes are centrally mediated. The following three specific aims are intended to test the main hypothesis that sleep deprivation results in hypothalamic dysfunction: Aim 1: To determine whether centrally-mediated hypothyroxinemia is due to deficient proTRH expression and TRH secretion in sleep-deprived animals. Proposed studies will determine whether TRH mRNA expression in the paraventricular nucleus and TRH content in the median eminence are suppressed and unresponsive to low T4, indicating impaired thyroid hormone regulation at the level of the hypothalamus. The pathway of T3 feedback to PVN neurons will be examined to determine the degree of up-regulation in response to low T4. Potential TRH responsiveness of thyrotrophs will be assessed by evaluating TRH receptor mRNA expression in the pituitary. Aim 2: To identify regulatory mechanisms responsible for reduced growth hormone and prolactin levels in sleep-deprived rats. Proposed studies will examine the regulation of PRL and GH in individual rats during the course of sleep deprivation by studying stimulatory and inhibitory mechanisms and response that could be responsible for the deficiency at the hypothalamic and pituitary levels. Aim 3: To delineate effects of sleep deprivation on thyroid hormone processing in the brain. Low thyroid hormone concentrations in sleep-deprived rats imply decreased T4 availability for import to the brain and ensuing centrally-mediated dysfunction common to the clinical hypothyroid state. Proposed studies will examine the content and regulation of iodothyronines in the sleep deprived brain. These studies will delineate the abnormalities in brain endocrine regulation resulting from sleep deprivation and determine the mechanisms responsible for peripheral endocrine changes that underlie its associated systemic pathologies.

Project Title: NEUROPEPTIDE CORTISTATIN AND SLEEP Principal Investigator & Institution: De Lecea, Luis; Scripps Research Institute Tpc7 La Jolla, Ca 92037 Timing: Fiscal Year 2002; Project Start 30-SEP-1997; Project End 30-JUN-2007 Summary: (provided by applicant): Cortistatin is a neuropeptide that has a strong similarity to somatostatin and selectively induces slow wave sleep, presumably by antagonizing the effects of the neurotransmitter acetylcholine on cortical excitability. Preprocortistatin is exclusively expressed in a subset of cortical and hippocampal interneurons that utilize GABA as their neurotransmitter. These features and others make cortistatin a sleep factor that may have a major role in cortical synchronization and the maintenance of slow wave sleep. During the period of the grant entitled "Neuropeptide cortistatin and sleep," three animal models have been generated, cortistatin-overexpressing transgenic mice, cortistatin systemic knock-out and cortistatin conditional knock-out mice. In this competitive renewal, cortistatin-deficient (cst ko) mice will be studied using anatomical, behavioral, electrophysiological and molecular methods. Cst ko mice will be analyzed for anatomical and developmental abnormalities. Since the activity of cortical interneurons is important for the maintenance of slow wave sleep electrophysiological measures of excitability will be recorded in hippocampal slices of cst ko mice. The consequences of cortistatin mis-expression on sleep- and circadian-related processes will be studied in mice with null mutations in the cortistatin and somatostatin genes. Finally, the molecular consequences of cortistatin and somatostatin deficiency will be studied using oligonucleotide-based microarrays and alternatively with differential display methods. Completion of this proposal will unambiguously address the role of cortistatin and somatostatin peptides in sleep regulation, delineate their signaling pathway and analyze possible cross-talk or genetic compensation, which may yield therapeutic applications and a better understanding of human sleep disorders in which cortical activity is affected.

Project Title: NIGHT SHIFT WORKERS AND HORMONE LEVELS IN WOMEN Principal Investigator & Institution: Davis, Scott; Professor of Epidemiology; Fred Hutchinson Cancer Research Center Box 19024, 1100 Fairview Ave N Seattle, Wa 98109 Timing: Fiscal Year 2002; Project Start 11-SEP-2002; Project End 31-AUG-2006 Summary: (provided by applicant): The primary objective of the proposed study is to determine whether working at night is associated with decreased levels of the nocturnal urinary concentration of 6-sulphatoxymelatonin, and increased levels of luteinizing hormone (LH), follicle stimulating hormone (FSH), and estradiol in a sample of healthy women of reproductive age. Secondarily, this study is designed to investigate whether urinary levels of melatonin are lower and levels of reproductive hormones are higher during daytime sleep relative to nighttime sleep among women who work at night. Approximately 200 nurses who work the night shift exclusively and 150 nurses who work the day shift exclusively will be recruited as volunteers in the Seattle metropolitan area. Eligible participants must be between the ages of 20 and 40, employed for at least 20 hours/week, resident of King or Snohomish County, do not take oral contraceptives or other hormone preparations, and have no personal history of breast cancer. In addition, the night shift nurses must normally sleep at night during off days. This study will employ a design which allows for both between-subject comparisons of night shift v. day shift workers, and within-subject comparisons during day sleep v. night sleep among the night shift workers. Participation will span two months. In the first month

the study will evaluate menstrual cycle regularity, determine the day of ovulation using a commercial kit, conduct a personal interview regarding employment and reproductive history, assess the participant's ability to adjust to shift work, and collect a blood sample. In the second month urine sample collections will be scheduled during both work and sleep periods, and will take place in the early to mid-luteal phase of each participant's cycle. Sleep patterns will be measured via actigraphy during the sleep periods corresponding to urine collection. Oral temperature data will be collected during waketime in the night shift workers to determine temperature amplitude. Information will be collected on factors which may be related to the hormones under study, such as alcohol consumption, medication use, and hours of daylight during sample collection. Urine samples will be assayed for the primary urinary metabolite of melatonin, 6sulphatoxymelatonin, and levels of LH, FSH, and estradiol.

Project Title: OPTIMIZATION OF AN IMPLANT TO TREAT SLEEP DISORDERS Principal Investigator & Institution: Metzger, Anja K.; Restore Medical, Inc. 2800 Patton Rd Saint Paul, Mn 55113 Timing: Fiscal Year 2003; Project Start 01-JUN-2003; Project End 30-NOV-2003 Summary: (provided by applicant): Snoring and obstructive sleep apnea are part of sleep disordered breathing (SDB) continuum. Beginning with mild snoring, this continuum progresses to obstructive sleep apnea in those most severely afflicted. SDB can result in sleep deprivation leading to daytime sleepiness, posing a risk for work place accidents, especially for those operating heavy machinery or motor vehicles. The long-term consequences of sleep-disordered breathing consist of an increased risk of high blood pressure, heart disease, and stroke. Current treatments to reduce snoring can be very painful and remain effective for only a short period of time before follow-up treatment is required. Pi Medical proposes a simple, relatively painless, placement of an implant to stiffen the soft palate, thereby, eliminating the vibrations known as snoring. The implantable device overcomes the disadvantages of current treatments by placing a permanent implant into the soft palate using a very simple procedure. The potential to use the implants to treat obstructive sleep apnea syndrome (OSAS) also exists. OSAS is characterized by intermittent closure of the pharyngeal airway during sleep resulting in episodes of hypoxemia and sleep disruption. Currently there are no treatments aimed specifically to treat the collapse of the pharyngeal walls. An effective treatment would be aimed at reducing the compliance of the pharyngeal walls; this would reduce their ability to collapse and alleviate upper airway obstruction without interfering with normal functions. The purpose of this research is to evaluate methods to maximize tissue ingrowth and fibrotic response to the implants with the expectation that this will increase the total stiffening effect of the implant and result in an implant that provides adequate properties to alter the compliance of the airway structures to 1) positively effect snoring levels or 2) prevent pharyngeal wall collapse associated with obstructive sleep apnea without affecting the normal function of the pharyngeal walls.

Sleep Deprivation
Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-JUL-2006 Summary: (provided by applicant): In children, unrecognized Sleep Disordered Breathing (SDB) may significantly contribute to learning and behavioral problems, and predispose to the development of cardiovascular problems. Adolescents may be predisposed to SDB because of weight gain or sleep restriction. However, the prevalence and impact of SDB in teenagers have not been systematically studied. Over the last 3 years, we have studied a unique cohort of 907 children (41% minority), ages 8-11, many who have been under observation since age 3 years. Our physiological and neuropsychological measurements provide fundamental data regarding the prevalence of SDB and risk factors for SDB in pre-pubertal children. Preliminary analyses indicate that children with snoring or SDB perform more poorly on a number of tests of cognitive function, and have more behavioral morbidity than do other children. We propose extending this study to assess the morbidity of SDB in adolescents (ages 13-16 years), addressing the extent to which SDB in childhood impacts behavior, cognitive functions, and neuro-endocrine responses important in the pathogenesis of cardiovascular disease or diabetes. We hypothesize that the effects of sleep fragmentation, reduced slow wave sleep and sleep-associated intermittent hypoxemia may lead to deficits in executive functions, insulin sensitivity, and abnormalities in the somatotropic axis. We also will quantify the impact of putative risk factors on adolescent SDB, including race/ethnicity, overweight, small pharyngeal size, prematurity, familial SDB, and SDB at ages 8-11 years. For efficiency, we will perform stratified sampling of 250 children from this cohort (125 with habitual snoring or sleep apnea at ages 8-11 yrs., and 125 children randomly selected from the remaining cohort, frequency matched by gender, term, and race). Children will undergo overnight stateof-the-art-sleep monitoring, a glucose tolerance test, acoustic rhino-pharnygometry, anthropometry, spirometry, blood pressure, and a focused battery of neuropsychological and behavioral assessments. Specimens for biomarkers and potential confounders (e.g, measures of puberty and thyroid status) will be collected, some both before and after sleep. First-degree relatives also will undergo sleep studies and relatives and children will have DNA collected for future studies. This proposal provides the opportunity to characterize the prevalence and morbidity of SDB in a wellcharacterized population-based sample, including a large proportion of minority and preterm adolescents who appeared to be at high risk for SDB at younger ages, and may be at increased risk for SDB-associated chronic morbidities, and poorer cognitive development. Comprehensive data collection and statistical analyses will permit identification of potential pathophysiological mechanisms for, and effects of, SDB.

Project Title: PREDICTORS OF ADVERSE METABOLIC EFFECTS OF SLEEP LOSS Principal Investigator & Institution: Spiegel, Karine; Free University of Brussels 50 Ave Franklin Roosevelt Brussels, Timing: Fiscal Year 2003; Project Start 30-SEP-2003; Project End 31-JUL-2007 Summary: (provided by applicant): Chronic sleep loss, obesity and sleep-disordered breathing (SDB) are increasingly common in industrialized countries. Sleep curtailment in healthy young lean adults results in the development of components of the metabolic syndrome, including reduced glucose tolerance and/or insulin resistance, elevated evening cortisol levels, increased cardiac sympatho-vagal balance, and a risk of weight gain resulting from reduced leptin levels and increased hunger and appetite. The studies proposed in the present application build on novel findings from our group that indicate that obese individuals may be more at risk for further weight gain than lean

individuals in conditions of sleep loss, and that individuals levels of slow wave activity (SWA), a stable trait-dependent marker of deep sleep, may predict subjective vulnerability to sleep loss, and are also likely to predict the severity of adverse metabolic and cardiovascular consequences of sleep loss. We therefore propose to characterize sleep architecture, autonomic nervous system (ANS) activity, and biomarkers of the metabolic syndrome in three groups of middle aged (35-50 years old) subjects studied while they follow their usual sleep habits as well as during 4 days of sleep restriction and sleep extension, presented in randomized order in a cross-over design. The three groups of subjects will be healthy lean men and women, gender-matched individuals who are obese, and gender-matched individuals who are obese and also suffer from SDB. The specific aims are: 1. To test the hypothesis that baseline levels of SWA are lower in obese adults than in lean controls, and are even lower in obese subjects with SDB, and examine correlations between levels of SWA and sleep duration, ANS activity and biomarkers of the metabolic syndrome. 2. To test the hypothesis that sleep restriction, as compared to sleep extension, has adverse effects on biomarkers of the metabolic syndrome in lean adults, obese adults, and obese adults with SDB. 3. To test the hypothesis that the adverse impact of partial sleep loss on components of the metabolic syndrome is more important for obese adults than in lean adults, and more severe in obese adults with SDB than in those without SDB. This project capitalizes on our experience with human studies of "sleep debt" and on our extensive expertise in assessment of ANS activity to evaluate the role of the ANS as a mediator of the adverse health effects of chronic sleep loss.

Project Title: REDUCING STRESS /SLEEP DISTURBANCES IN CAREGIVERS OF AD Principal Investigator & Institution: Hall, Martica; University of Pittsburgh at Pittsburgh 350 Thackeray Hall Pittsburgh, Pa 15260 Timing: Fiscal Year 2003; Project Start 01-DEC-2002; Project End 30-NOV-2007 Summary: The stress of caregiving is associated with a number of adverse health outcomes including psychiatric morbidity, immune system dysregulation, increased susceptibility to illness and disease, and increased risk for mortality. Sleep complaints are common among caregivers, and stress-related sleep disruptions may signal vulnerability to, or play a causal role in, the adverse health consequences of caregiving. The general aim of this revised study is to test the efficacy of an intervention designed to reduce stress and improve sleep in a sample of spousal careqivers of patients with Alzheimer Disease (AD). The intervention will be compared to an attention-only control condition. Specific aims of this study are: 1. To characterize stress-related sleep disruptions in spousal caregivers of AD patients. 2. To test the short-term efficacy of a stress management+healthy sleep practices (SM+HSP) intervention for improving sleep and health outcomes in AD caregivers. 3. To test the durability of SM+HSP in AD caregivers. The study will include 60 spousal caregivers of AD patients who will be randomly assigned to one of two treatment conditions. The SM+HSP intervention will consist of eight weekly in-home sessions that will focus on information support, skills training, affective self-management, and healthy sleep practices. Individually, these components have been shown to be efficacious for reducing stress or improving subjective sleep complaints in AD caregivers. The control condition will include eight weekly in-home sessions which will focus on diet and food intake. Treatment integrity will be monitored by audiotape recordings. The program project measures battery (Agebat) and additional measures specific to caregiving will be administered at four

Sleep Deprivation
time points: prior to randomization, immediately post-intervention, and at 6- and 12month follow-up visits. Project -specific data will be used to evaluate treatment efficacy and relationships among caregiver stress and sleep. Relationships among stress, sleep, and health will be more fully evaluated using program-wide data collected in Project 15. Our program-wide aim is: to characterize the impact of stress-related sleep disruptions on health in older adults, including AD caregivers, recent widows/widowers, patients with insomnia in primary care settings, and healthy elders above the age of 75 years. The main hypotheses to be tested within the individual project are that the stress of caregiving has a detrimental effect on sleep and that stressrelated sleep disruptions, in turn, negatively impact health and well-being. It is hypothesized that, relative to the attention-only control condition, the active intervention (SM+HSP) will result in improvements in sleep and subsequent improvements in health and well-being.

Principal Investigator & Institution: Greco, Mary A.; Sri International 333 Ravenswood Ave Menlo Park, Ca 94025 Timing: Fiscal Year 2002; Project Start 01-JUL-2001; Project End 31-MAY-2005 Summary: The neuronal circuitry underlying sleep-wakefulness is beginning to be understood. Changes in the release of neurotransmitters across sleep-wakefulness are well documented. The intracellular events associated with the activity of these neurons across sleep-wakefulness, however, are not clear. The available evidence suggests that the transcriptional activation of genes occurs during sleep, indicating that changes in protein and mRNA expression are likely to occur during sleep as well as waking states. The function of sleep is not known. One hypothesis is that sleep serves to replenish biomolecules depleted during waking. If sleep serves such a function, The intracellular environment of brain centers involved in sleep- wakefulness will support biosynthesis. The main hypothesis of this proposal is that changes in the expression of key enzymes associated with neurotransmitter synthesis occur sleep- wakefulness to maintain neurotransmitter stores. To test this hypothesis, the expression of choline acetyltransferase (ChAT), the enzyme that synthesizes acetylcholine will be examined. Specific aim 1 will test the hypothesis that chat mRNA is increased during sleep. In these experiments, mRNA levels will be examined during waking, non-REM and REM sleep states that occur across a 24-hour period. Specific aim 2 tests the hypothesis that protein activity and/or protein levels vary across individual sleep bouts over a 24-hour period. Specific aims 3 and 4 will test the hypothesis that sleep loss effects mRNA expression (Specific aim 3) and protein expression (Specific aim 4). In these experiments, the reversibility of the effects of sleep loss will also be monitored during the recovery sleep period. Sleep disorders affect approximately 70 million Americans with associated costs estimated at billions of dollars in lost revenue per year. By identifying how sleep might replenish key enzymes in neurotransmitter synthesis, we will advance our knowledge of sleep. The experiments proposed are the first steps in the identification of cellular mechanisms effecting acetylcholine synthesis across sleep-wakefulness.

Project Title: REM SLEEP DEPRIVATION, HYPOXIA, AND HIPPOCAMPAL FUNCTION Principal Investigator & Institution: Gozal, David A.; Professor and Vice-Chair for Research; Pediatrics; University of Louisville University of Louisville Louisville, Ky 40292 Timing: Fiscal Year 2002; Project Start 01-SEP-2000; Project End 30-JUN-2004 Summary: Obstructive sleep apnea syndrome (OSAS) is a frequent condition affecting up to 5 percent of the population, and is characterized by repeated episodes of hypoxia and recurrent EEG/behavioral arousal, particularly during REM sleep. When untreated, OSAS is associated with significant neurocognitive morbidities such as excessive daytime sleepiness and diminished intellectual performance, attention span, learning and vigilance. However, the relative contributions of REM sleep deprivation (REMSD) and episodic hypoxia to OSAS-associated neurocognitive dysfunction remain unclear. To test the hypothesis that REM sleep deprivation and episodic hypoxia affect learning and memory in an additive fashion, four major specific aims will be examined in a young adult rat model as follows: (1) The acquisition and retention of Morris water maze task paradigms will be assessed in conscious 55-60-day old male rats after either 4day REMSD using the inverted flower pot technique, 14-day episodic daytime hypoxia (EHYP), or the combination thereof (REMSD-EHYP); (2) The effect of such exposure paradigms on long-term potentiation (LTP) within the CA1 region of the hippocampus will be examined using neurophysiological extracellular recordings of the in vitro hippocampal slice preparation; (3) Changes in ionotropic glutamate receptor distribution and in apoptosis within the hippocampal formation and neocortex will be determined using immunohistochemical and wester blot approaches in naive and maze trained animals following REMSD, EHYP, or both; (4) Alterations in early gene induction (c-fos) elicited by maze learning procedures will be further assessed in the hippocampus of REMSD, EHYP, and REMSD-EHYP by immunohistochemistry and AP1 electromobility shift assays. These e xperiments will extend our understanding on potential mechanisms and interactions underlying the decreased performance that occurs in particular neurocognitive functions of untreated OSAS patients. In this context, REMSD, EHYP, or both would lead to either up-regulation or down-regulation of specific ionotropic glutamate receptor complexes, induce apoptosis, and thereby modify early gene activation patterns associated with learning or retention of newly learned tasks. Such alterations in receptor-signal transduction pathways could also lead to both short- and long- term changes in neuronal excitability and synaptic transmission within brain regions with important and defined roles in memory formation and learning such as the hippocampus.

Previous work in this laboratory has shown that those depressed who remain untreated are more likely to remit over a one year period if they demonstrate increased REM pressure (higher eye movement density, more frequent REM episodes, and reduced REM latency), and if they demonstrate higher proportions of negative affect dreams in the first half of the

Sleep Deprivation
night than in the last (a 'working through' of affect within the night). Thirty-two depressed volunteers with equal numbers of males and females are tested for mood before and after each of two nights of laboratory-monitored sleep on three occasions over a five month period. REM sleep will be interrupted to retrieve dream reports every second night. This manipulation also increases REM pressure. Data will be analyzed for differences between sex groups for 1). the effects of REM pressure (between sleep through and REM interrupted nights) 2). Dream affect change (between half nights), 3). dream-like quality of reports, and 4). problem focus in dream content on overnight mood regulation and on remission of depression. Findings will contribute to an understanding of REM sleep and dream function, and the sex difference in rates of depression. This study will also have implications for the treatment of depression.

Project Title: SLEEP AND NEURAL PLASTICITY IN DEVELOPING NEOCORTEX Principal Investigator & Institution: Frank, Marcos G.; Physiology; University of California San Francisco 500 Parnassus Ave San Francisco, Ca 941222747 Timing: Fiscal Year 2002; Project Start 05-AUG-2002; Project End 31-DEC-2002 Summary: (provided by applicant): This application proposes neurophysiological studies to determine the role of sleep in the development and plasticity of the mammalian visual cortex. Our previous research has demonstrated a role for sleep in the plasticity elicited by monocular deprivation (MD) during the critical period for visual development in the cat. These findings suggest an important role for sleep in the developing brain and have important implications for our understanding of cortical plasticity, learning and memory, and the function of sleep. In addition to providing insights into these areas of study, the proposed studies should provide important information regarding the role of sleep in human neural development, and the longterm consequences of sleep loss on the developing brain. The overall goal of the proposed studies is to determine the contribution of rapid-eye-movement (REM) and nonREM sleep to two forms of developmental plasticity in visual cortex. Short periods of MD during the cat critical period trigger rapid remodeling of thalamocortical circuits in primary visual cortex in favor of the open eye. A related form of synaptic plasticity, elicited by opening the previously closed eye and closing the previously open eye (reverse-MD) can produce recovery of cortical function. We will first determine the contribution of each sleep state to the cortical plasticity elicited by MD. We will then determine if the effects of sleep on cortical plasticity are mediated by the patterns of neural activity present in REM or nonREM sleep. We will then investigate the role of sleep in the cortical plasticity elicited by reverse-MD. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

quantity and quality of sleep between youth with varying degree of nighttime asthma symptoms and youth not having asthma; and determine which subjective and objective measures or combination of measures of sleep are the best predictors of daytime tiredness and activity limitations in children having asthma. The study uses a 2 group (asthma/no asthma) experimental design. Fifty children (half with asthma) will participate with a parent. Parent and child will provide historical information on sleep and breathing problems at night; 7 days of diary report on the child s sleep, respiratory symptoms, pulmonary function and daytime tiredness and activity limitation due to breathing problems. The child will wear a wristwatch like band to monitor their movements during 7 nights of sleep at home and then come into the sleep laboratory or more in-depth monitoring of sleep and pulmonary function. The child's usual bedtime will be used during the first Bedtime will be delayed by 4 hours the second night to intensify sleep to in-laboratory sleep monitoring determine if this intensification has a detrimental effect on the child's pulmonary function. Innovative, non-invasive markers will be used to evaluate changes in autonomic system function (heart rate variability) and pulmonary inflammation (exhaled nitric oxide) during the in-laboratory sleep nights. Examining this data in the context of the adult data already reported in the literature should allow identification of possible development differences in the influence of sleep on nocturnal asthma symptom expression that would be worthy of further study. The information gained is critical to practicing health care providers who are working to quell rising ast morbidity particularly in ethnic minority children living in poverty.

Project Title: SLEEP CONTROL BY THERMOSENSITIVE NEURONS Principal Investigator & Institution: Mcginty, Dennis J.; Adjunct Professor; Psychology; University of California Los Angeles 10920 Wilshire Blvd., Suite 1200 Los Angeles, Ca 90024 Timing: Fiscal Year 2002; Project Start 01-SEP-1992; Project End 30-JUN-2005 Summary: (applicant's abstract): We propose to study neurophysiological mechanisms mediating the regulation of serotonin-containing neurons in the mammalian dorsal raphe nucleus (DRN) by the hypnogenic system in the preoptic hypothalamus and adjacent basal forebrain (POA/BF). Activation during spontaneous sleep of warmsensitive neurons (WSNs) and deactivation of cold-sensitive neurons (CSNs) plays a critical role in the POA/BF hypnogenic process. WSNs and CSNs are identified by responses to local warming and cooling. Previous evidence shows that the POA/BF also contains both REM-facilitatory and REM-inhibitory processes. Suppression of DRN serotonergic neuronal discharge was shown to play a role in both NREM sleep onset and REM sleep triggering. Recent anatomical and physiological evidence shows that activation of the POA/BF WSN/CSN hypnogenic system can induce suppression of DRN neuronal activity, suggesting a mechanistic basis for NREM-REM coordination. We have developed a testable 2-stage model of regulation of DRN and REM triggering by the POA/BF. Aim 1 is to quantify the regulation of REM sleep control by POA/BF temperature-sensitive neurons. Aim 2 is to use microdialysis to confirm that POA/BF warming induces increased release of the inhibitory neurotransmitter, gammaaminobutyric acid (GABA) in DRN, and that postsynaptic blockade of GABA in DRN prevents POA/BF-induced changes in NREM EEG deactivation and REM-triggering. Aim 3 will combine microdialysis and neuronal unit recording in the DRN to assess hypotheses that GABA release induced by POA/BF warming regulates DRN neuronal discharge and that DRN neuronal discharge regulates REM triggering. Aim 4 will use
50
Sleep Deprivation
techniques to generate REM-enriched sleep and the method of proto-oncogene c-fos expression to label neuronal activity in order to assess a hypothesis that a subregion of the POA/BF, the peri-ventrolateral preoptic area (peri-VLPO) contains REM-selective neurons. Aim 5 is confirm the existence of REM-selective neurons in peri-VLPO using chronic neuronal unit recording techniques. Aim 6 is to use microdialysis of a GABA agonist, muscimol, to inactivate the peri-VLPO area to assess the hypothesis that this region is essential for REM-triggering. These studies will provide a new model of interactions of NREM and REM sleep mechanisms and will contribute to the understanding of human diseases including narcolepsy and affective disorder in which NREM-REM coupling is disordered.

The career developmental and research plan are designed to allow the applicant to reach this goal. The applicant intends to supplement his background in electrophysiology with techniques in neurochemistry (microdialysis of biogenic monoamines in behaving animals and high performance liquid chromatography) and molecular biology, which he plans to acquire during the Award period. The applicant intends to apply his expertise in sleep physiology to study the neurobiological mechanisms underlying the antidepressant effects induced by sleep deprivation. In this proposal, and as a first step in an overall research program, the applicant will concentrate on the effects of sleep deprivation on serotonin (5-HT) activity. His specific aims are as follows. 1) Sleep deprivation induces changes in 5-HT release in forebrain structures and is accompanied by sustained high levels of 5-HT in the raphe. 2) Sleep deprivation changes the activity of 5-HT1A and 5-HT1B autoreceptors. The applicant hypothesizes that sleep deprivation blocks the effects of 5HT1A and/or 5HT1B agonists on 5-HT release, as well as the amounts and synthesis of 5-HT1A and 5-HT1B autoreceptors. 3) Sleep deprivation modifies the synthesis of 5-HT. In addition to studying the overall effect on 5-HT synthesis, the applicant will determine the effect of sleep deprivation on brain tryptophan concentration, gene expression of tryptophan hydroxylase (TPH, the rate-limiting enzyme in the biosynthetic pathway), and TPH activity. A better understanding of these sleep deprivation-related changes has the potential to advance our knowledge, both in sleep physiology and antidepressant mechanisms of action.

Summary: (Applicant's Abstract) Marijuana and alcohol are drugs that contribute to automobile accidents when used separately and in combination. A further danger to adults who drive after late-night drug use is sleep deprivation. While many postaccident blood analyses have implicated marijuana and alcohol, no controlled empirical studies have quantified the combined behavioral and subjective effects of sleep deprivation with either marijuana or marijuana-alcohol combinations. The novelty of this project is its use of controlled Sleep Laboratory measurements, a driving simulator, computerized body sway measurement, a test of divided attention, and self-report mood scales to assess the various ways sleep deprivation and alcohol impair a driver who uses marijuana. The project has three specific aims. The first aim is to quantify how alcohol alters the effects of marijuana on mood, equilibrium, attention, and simulated automobile driving. The second aim is to quantify how partial sleep deprivation alters the effects of marijuana on these measures. The third aim is to quantify the effects of sleep deprivation on marijuana-alcohol combinations. Three studies using randomized placebo controlled designs are proposed. In each study, subjects will smoke a marijuana cigarette (0, 1.77, or 3.95% delta 9 THC) in two or three separate conditions. Study 1 will manipulate a concurrent dose of alcohol (0.0, 0.5, or 0.8 g/kg). Study 2 will manipulate pre-session sleep hours (8 vs. 3). Study 3 will add the expectation and experience of alcohol to the conditions of Study 2, with each subject drinking a dose of alcohol (0.0, 0.5, or 0.8 g/kg) before testing. The dependent variables to be studied include 1) body sway as measured by computerized dynamic posturography, 2) subjective effects scales (Profile of Mood States and Visual Analog Scales), 3) the Stroop Color Test of divided attention, and 4) brake latency within the driving simulator. By clarifying the separate and combined effects of marijuana, alcohol, and sleep deprivation on these ecologically valid measures, the results will contribute to the prevention of drug-related highway fatalities.

Project Title: SLEEP DEPRIVATION, EEG, & FUNCTIONAL MRI IN DEPRESSION Principal Investigator & Institution: Clark, Camellia P.; Psychiatry; University of California San Diego 9500 Gilman Dr, Dept. 0934 La Jolla, Ca 92093 Timing: Fiscal Year 2002; Project Start 20-FEB-2001; Project End 31-JAN-2006 Summary: (Adapted from applicant's abstract): The objective of this 5-year Mentored Clinical Scientist Development Award for Cametlia Clark, M.D. is to develop the candidate's expertise in functional magnetic resonance imaging (MRI) while building on her previous skills in neuroimaging and sleep research. This goal will be accomplished through a carefully designed training plan involving didactic courses and mentorship by experts (at and outside UCSD) in basic neuroscience, structural MRI, functional MRI (fMRI) physics, sleep and affective disorders research, and statistics as well as intensive instruction in fMRI research in a setting featuring state-of-the-art scanners, innovative pulse sequences (particularly perfusion-weighted), and the first fMRI studies utilizing sleep deprivation (SD) to study cognitive function in normal subjects (published recently in Nature and NeuroReport. This training program will enable Dr. Clark to complete the transition to independent investigator and provide the foundation for a long-term research program utilizing fMRI and polysomnography to investigate brain function in affective disorders. The research plan utilizes one night of partial SD (PSD), an excellent model of antidepressant treatment which is fast-acting, and does not require medications. The applicants hypothesize: I) depressed responders' baseline perfusion signal intensity in the ventral anterior cingulate (BA 25 and ventral 24) / medial prefrontal cortical (BA 32) areas will be greater than that of nonresponders and controls;
52
Sleep Deprivation
2) following PSD, perfusion in the ventral anterior cingulate (BA 25 and ventral 24) / medial prefrontal cortical (BA 32 and 10) areas will significantly decrease in responders only. The applicants will also look for between-groups and within-groups differences in other regions where functional abnormalities have been reported in depression, including (but not limited to) dorsal anterior cingulate, dorsolateral prefrontal cortices, medial frontal cortices, amygdala, hippocampus, thalamus, and basal ganglia. Finally, the applicants will look for possible between-groups structural MRJ differences, which could potentially confound fMRI analyses. FMRI perfusion data will be analyzed by the analysis of variance algorithm in AFNI (Analysis of Functional Neural Images) software.

Project Title: SLEEP DISORDERED BREATHING AND GLUCOSE REGULATION Principal Investigator & Institution: Polotsky, Vsevolod Y.; Medicine; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2002; Project Start 01-JUL-2002; Project End 30-JUN-2007 Summary: provided by applicant): Sleep Disordered Breathing (SDB) and type 2 diabetes mellitus are serious health problems associated with obesity. Recent epidemiological studies have shown that SDB may be linked to insulin resistance and glucose regulation, independent of obesity. However, the mechanisms by which SDB may affect glucose and insulin regulation are unknown. Putatively, the intermittent hypoxia (IH) and sleep fragmentation of SDB may impact on glucose regulation. Hypoxia could affect the insulin-glucose axis through upregulation of hypoxia-inducible factor- I alpha (HIF- 1alpha) which activates expression of glucose transporters, resulting in decreased blood glucose levels. On the other hand, sleep fragmentation could lead to stress and activation of insulin counter-regulatory hormones, such as cortisol and epinephrine, resulting in increased blood glucose levels. In our Preliminary Data we show that IH causes a biphasic response consisting of a decrease in blood glucose levels after one week followed by a rise in blood glucose after three weeks of exposure. Furthermore, the absence of the metabolic hormone leptin resulted in a more pronounced hyperglycemic phase in response to IH compared to wildtype mice. Our major hypothesis is that SDB causes biphasic changes in glucose homeostasis. The early decrease in blood glucose is due to hypoxic activation of HIF- 1alpha and upregulation of glucose transporters. The late increase in blood glucose is due to sleep fragmentation activating insulin counter-regulatory hormones, and this effect is exacerbated by leptin deficiency. In order to test our hypotheses we will utilize a mouse model of IH as well as a mouse model of SDB. We will use wildtype mice, with and without dietary obesity, as well as leptin deficient ob/ob mice and transgenic HIF- 1alpha mice. In Specific Aim I we will determine-nine the time course of changes in blood glucose, serum insulin, insulin counterregulatory hormones, and tissue glucose transporters during IH in lean and obese mice. In Specific Aim 2 we will separate the effects of IH and sleep fragmentation on glucose regulation. In Specific Aim I we will specifically examine the role of HIF- 1alpha and leptin in glucose responses to IH using transgenic mice. Thus, this study will examine mechanistically how SDB affects glucose regulation, which could have a significant impact on both fields of SDB and diabetes.

Project Title: SLEEP DISRUPTION IN NEW PARENTS: AN INTERVENTION TRIAL Principal Investigator & Institution: Lee, Kathryn A.; Professor and Livingston Chair; Family Health Care Nursing; University of California San Francisco 500 Parnassus Ave San Francisco, Ca 941222747 Timing: Fiscal Year 2002; Project Start 01-JAN-2001; Project End 31-DEC-2003 Summary: This longitudinal study utilizes a stress and coping framework to test an intervention to minimize the stress of sleep disruption and thereby improve the outcomes for new parents after the birth of their first infant. Data from the principal investigator's previous research and knowledge of sleep hygiene principles provide the basis for this proposal. The primary aim is to test the effects of an environmentalbehavioral intervention on sleep, fatigue, well-being, and marital satisfaction. This intervention will be introduced prior to delivery to allow the couple to adapt to the equipment involved in the intervention. Hypotheses will be tested using repeated measures analysis of variance to determine mean group differences. It is expected that: 1) The experimental group of new mothers (n=60) and new fathers (n=60) will have significantly fewer awakenings, and higher sleep maintenance than control mothers (n=60) and fathers (n=60) at all 4 postpartum time points; 2) The experimental group of new mothers and new fathers will report significantly lower fatigue and higher wellbeing and marital satisfaction compared to controls at all four postpartum time points (2, 4, 8, and 12 weeks). A secondary aim is to describe the success by which new parents incorporate this intervention into their lifestyle and evaluate its feasibility for other firsttime parents. Level of satisfaction with the intervention package will be ascertained for both experimental fathers and experimental mothers before and after mothers return to work. Results from this study will be useful in developing an educational intervention package for distribution to all adults preparing for parenthood.

Project Title: SLEEP DISTURBANCE IN MARIJUANA WITHDRAWAL Principal Investigator & Institution: Bolla, Karen I.; Associate Professor; Neurology and Neurosurgery; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2003; Project Start 10-SEP-2003; Project End 30-JUN-2005 Summary: (provided by applicant): Marijuana is the most widely used illicit drug in the United States. Heavy marijuana users who attempt to stop using marijuana frequently report sleep disturbance, restlessness, nervousness/anxiety, increased aggression, and appetite changes. We believe that sleep disturbance may pose an enormous hindrance to successful cessation of heavy marijuana use. Surprisingly, despite several subjective reports of sleep disturbance in newly abstinent heavy marijuana users, there have been no studies using objective polysomnographic (PSG) measures validating these subjective reports. Therefore, this study is highly significant and very innovative because in addition to collecting subjective measures of withdrawal symptoms, we will obtain repeated objective measures of sleep architecture using standard PSG procedures. We will determine if there are objective polysomnographic findings of sleep disturbance in marijuana users (N=16) abstaining from drug use for 14 days in an inpatient setting at NIDA-IRP. Sixteen non-drug using controls, will be included for comparison and matched to the marijuana group on age, gender, and sleep-wake pattern. The control group will reside on our GCRC for 3 days. Baseline sleep-wake patterns will be estimated in both groups with actigraphy and sleep log recordings for 5 days prior to withdrawal/admission. The marijuana users will be transferred from NIDA-IRP to the
54
Sleep Deprivation
GCRC core sleep lab for PSG recording. We will obtain PSG sleep measures of sleep onset, sleep maintenance, and restlessness at three separate times over 14 days of withdrawal and compare these to PSG measures obtained from the comparison group. Moreover, changes over time will be determined in the marijuana users. We will also determine if marijuana users have delayed sleep phase syndrome, a possible cause of sleep onset difficulty, by measuring dim light melatonin. The long-term goal of this research is to determine if heavy marijuana use is associated with objective sleep abnormalities as measured by polysomnographic procedures. Such findings could lead to new treatments for alleviating the unpleasant symptoms of marijuana withdrawal. For example, delayed sleep phase syndrome, one cause of insomnia, could be treated with light therapy, the same treatment used successfully for treating seasonal affective disorder. New treatments for alleviating the unpleasant symptoms of marijuana withdrawal would likely increase the number of heavy marijuana users who successfully complete treatment.

Project Title: SLEEP FRAGMENTATION EFFECTS ON MURINE CII-INDUCED AR Principal Investigator & Institution: Postlethwaite, Arnold E.; Medicine; University of Tennessee Health Sci Ctr Memphis, Tn 38163 Timing: Fiscal Year 2002; Project Start 25-SEP-2002; Project End 31-AUG-2004 Summary: (provided by applicant): Patients with rheumatoid arthritis (RA) and other chronic arthritides have partial chronic sleep deprivation (PCSD) possibly related to the pain and inflammation associated with their condition. It is unknown what effect PCSD has on the immune and non-immune mediated arthritic processes of RA and related arthritides. Recent work in laboratory animals and humans indicates that sleep deprivation produces immune-related consequences. The overall goal of this study is to induce chronic, partial sleep fragmentation in DBA/1 lac mice during the evolution of the primary immune resonse to ovalbumin (OVA) in mice and during the evolution of type II collagen (CII)-induced arthritis (CIA) in this same mouse strain. We will test the hypothesis that PCSD in DBA/1 lac mice will result in alterations in the immune response to OVA and severity of arthritis. The approach will Ibe to tailor an experimental chronic sleep deprivation appartus to fit the mouse, develop and lvalidate a computerized program, implement experimental conditions of selective partial sleep Ideprivation in a consistent and reliable manner, and then assess the effects of PCSD on immune Iresponse to OVA and arthritis induced by immunization with CII. The following specific aims will address this hypothesis: Specific Aim 1: Assess sleep patterns in arthritic mice; Specific Aim 2: Conduct total sleep deprivation in mice to produce partially sleep-deprived mice; Specific Aim 3: Determine whether chronic partial sleep deprived DBA/1 lac mice immunized with OVA develop altered immunity to OVA; and Specific Aim 4: Determine whether chronic partial sleep-deprived DBA/1 lac mice immunized with CII have alterations in the incidence and/or severity of arthritis. Results of the study will provide a basis for submitting an R01 grant to explore mechanisms by which partial sleep deprivation in DBA/1 lac mice alter the immune response to antigen and arthritis development.

Project Title: SLEEP MECHANISMS IN CHILDREN: ROLE OF METABOLISM Principal Investigator & Institution: Haddad, Gabriel G.; Pediatrics; Yeshiva University 500 W 185Th St New York, Ny 10033
Studies
55
Timing: Fiscal Year 2002; Project Start 23-SEP-2002; Project End 31-JAN-2007 Summary: (provided by applicant): Sleep and the neurobiological mechanisms controlling sleep/wakefulness have been an enigma in spite of important recent advances in the field. Although it is well known now that sleep affects a variety of systems, including the cardio-respiratory, endocrine and autonomic systems, we still do not understand why we sleep and the mechanisms that control sleep. For example, we do not have a good understanding of the mechanisms that induce or maintain sleep or those mechanisms that are activated with sleep deprivation. One of the potentially important areas that have started to develop is the role of brain metabolism in sleep. Although metabolic studies during sleep have been done in the past few decades, new developments in brain imaging and spectroscopy have made it possible only recently to examine the importance of metabolism in sleep research. Furthermore, and of major interest, is the growing evidence that glia play a critical role in maintaining neuronal function through metabolic support through glutamate re-cycling and possibly by providing neurons with substrates for glucose oxidation. Glycogen is found only in glia and hence glycogen metabolism, the glutamine-glutamate cycling and glucose oxidation involve links between glia and neurons. Hence, in order to understand sleep and its mechanisms, it becomes important to study the functional integrity and coupling of neurons and glia and their relationship as a function of state. For conceptual reasons and in order not to complicate the experimental matrix, we will focus this application on stage III-IV sleep and will address our questions comparing this sleep stage to a well defined state of wakefulness. Furthermore, since previous studies have taught us about sleep and its mechanisms by studying sleep deprivation, we will, in a subset of our children, address the same questions after sleep deprivation. Our specific hypotheses are as follows: 1. Stage IV sleep has a lower metabolic requirement and a lower glutamate turnover rate (tricarboxylic acid cycle rate) in both neurons and glia, as compared to wakefulness. 2. As compared to wakefulness, sleep stage IV is characterized by a lower rate of brain neuronal glutamate release and glial glutamate uptake in children; this reduced glutamate/glutamine cycling during this sleep stage in brain of children is prevented by sleep deprivation. 3. Brain glycogen content increases during the course of sleep in children and sleep deprivation markedly lowers glycogen content. Our long term aims are a) to better understand sleep and b) to be able to better understand diseases that afflict children or adult and which impact on their sleep or diseases that are sleep-related that impact on other functions including neurocognitive, cardiovascular or behavioral functions. As seen from reviewing the state-of-the-art above, there are major gaps in our knowledge and this application focuses on a number of these gaps.

Project Title: SLEEP MEMORY: A MOLECULAR AND GENETIC ANALYSIS Principal Investigator & Institution: Abel, Edwin G.; Assistant Professor; Biology; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2002; Project Start 30-SEP-1999; Project End 30-JUN-2004 Summary: The goal of our research is to elucidate the molecular machinery underlying sleep and to define the role of sleep in the consolidation of long-term memory. Sleep is involved in many physiological processes, and disturbances in sleep are a hallmark of many diseases, including neurodegenerative disorders such as Alzheimer's disease, in which memory deficits are prominent. An understanding of the relation between sleep dysfunction and memory loss may help us to better define the pathophysiology of these diseases. We are interested in bridging past behavioral studies, which have shown that
56
Sleep Deprivation
sleep is needed for the consolidation of memory, with current knowledge about the molecular mechanisms underlying memory storage. Mice are an ideal system with which to explore the relationship between sleep and memory consolidation. Our recent work has used genetic and pharmacological approaches in mice to demonstrate that protein kinase A (PKA) activity is critically important for long-term memory storage. There are striking parallels between the effects of sleep deprivation and the effects of pharmacological manipulation of the PKA signaling pathway on the consolidation of memory. Both sleep deprivation and inhibition of PKA disrupt the consolidation of memory only at discrete times following training and these times vary depending on the strength of the training protocol. Based on this, we propose to examine the role of the cAMP/PKA/CREB signaling pathway in the behavioral effects of sleep deprivation on hippocampus-dependent tasks in mice. In Specific Aim 1, we will determine the effects of total sleep deprivation as well as rapid eye movement (REM) and non-REM (NREM) sleep deprivation on contextual fear conditioning, a single-trial hippocampusdependent learning task in mice. Specific Aim 2 will focus on biochemical and molecular assays to directly measure changes in PKA activity and phospho-CREB levels in the hippocampus after sleep deprivation and contextual fear conditioning. Specific Aim 3 will investigate the hypothesis that sleep may modulate memory storage through the prominent cholinergic flux to the hippocampus that occurs during REM sleep. In Specific Aim 4, we will examine sleep architecture in mice with genetic alterations in the cAMP/PKA/CREB signaling pathway to test the hypothesis that memory consolidation deficits in these mice are due to altered patterns of sleep. The broad-based experimental design of this proposal, using genetic, pharmacological, electrophysiological and behavioral approaches, will bring us closer to an understanding of the molecular and biochemical processes underlying sleep and enable us to define the role that sleep plays in memory consolidation.

Project Title: SLEEP/DOPAMINE PHENOTYPES IN GENETICALLY DISTINCT MICE Principal Investigator & Institution: Rye, David B.; Associate Professor; Neurology; Emory University 1784 North Decatur Road Atlanta, Ga 30322 Timing: Fiscal Year 2002; Project Start 30-SEP-1999; Project End 31-JUL-2004 Summary: (adapted from the applicants' absract) One poorly understood neuromodulator of state is the mesostriatal dopamine (DA) system, which not only promotes motivation/reward and movement, but also arousal (viz., wakefulness). Conversely, DA blockade and interruption of mesostriatal pathways slows movement and promotes sleepiness. The details of mesostriatal DA's effects upon wake/sleep rhythms, and sleep architecture, and the cellular and subcellular substrates involved remain poorly defined. Circadian and homeostatic wake/sleep factors affect mesostriatal circuit plasticity, but their functional import is also undefined. Mice with genetic deletions of the dopamine transporter (DAT-/-), their heterozygotes (DAT+/-), wild type littermates, the pure C57BL/6 and S129/sv strains from which the transgenics derive, and the DBA/2 inbred strain with known under expression of mesostriatal D2 receptors afford a means to probe DA's role in state control, and to account for genetic variation in wake/sleep phenotypes. Aim #1 proposes to characterize 24-hour motor activity patterns in relation to sleep/wake architecture in these mice. Motor hyperactivity in DAT -/- and DAT +/- during the subjective night yields to hypoactivity during subjective day suggesting a sleep/wake reversal in the face of chronically elevated synaptic DA (preliminary data). The mechanisms underlying a homeostatic
Studies
57
sleep drive powerful enough to overcome chronic DA elevations - if indeed sleep attends the observed hypoactivity - may reside in other proteins involved in mesostriatal DA transmission. Aim #2 therefore proposes to measure traditional DA markers, and molecularly defined D1 receptor, DAT and vesicular monoamine transporter (vMAT2) expression across 24-hours in limbic and motor striatal circuits to enhance interpretation of Aim #1 findings. Aim #3 investigates the effects of prolonged wakefulness induced by physical means, bupropion (a DAT blocker), and caffeine (an adenosine receptor blocker), on the mesostriatal DA system in these same mice. The investigators postulate that these transgenic and inbred mice will exhibit unique circadian rhythms of proteins mediating DA neurotransmission and unique responses of these proteins to prolonged wakefulness that may be treatment modality specific, much the same way that depressives differ in their response to REM-sleep deprivation, and narcoleptics differ from depressives in their REM-sleep responses to DAT blockade. Taken together, the findings will advance an understanding of how state might modulate the course and treatment of insomnia, depression, and neuropsychiatric diseases whose pathophysiologies are rooted in DA sensitive basal ganglia circuits.

Project Title: SOCIALIZATION OF INFANTS' STATE, ATTENTION, & AFFECT Principal Investigator & Institution: Super, Charles M.; None; University of Connecticut Storrs Unit 1133 Storrs-Mansfield, Ct 06269 Timing: Fiscal Year 2002; Project Start 01-SEP-2000; Project End 30-JUN-2004 Summary: The long-term goal of this study is to expand our knowledge of the early development of arousal, attentional and affective behaviors, especially as they are shaped by culturally specific caretaking practices. The research design will capitalize on a natural experiment in parallel communities in the Netherlands and the USA. Two groups of infants (60 in each community) will be followed from shortly after birth until age 2 years. Assessment procedures include parent interviews, diaries, and actigraph recordings of daily activities and rest, samples of salivary cortisol at specified times of the day, behavior observations in the home, parental ratings of temperament, evaluation of reactivity and adaptation to developmentally appropriate challenges, and reactions to DPT inoculations. Included for these latter two procedures is monitoring of autonomic nervous system functioning (heart rate) and endocrine functioning (cortisol). The project has three specific goals: 1) To replicate and extend, with a longitudinal design, conclusions established in previous cross-cultural comparisons regarding community differences in the amount and patterning of sleep, daytime arousal, management of attention, and affective expression during the first two years of life. These differences appear to correspond to the way parents in the two communities interact with their babies and organize daily life for them; 2) To examine in greater detail the involvement of biologic mechanisms in the developmental pathways identified, particularly those involving autonomic functioning and activity of the hypothalamic-pituitary-adrenal axis; 3) To arrive at a clearer understanding of diversity in normative biobehavioral development as regulated through cultural processes. The product of this study will be new knowledge about how culturally organized environments interact over time with developing biological and behavioral systems to yield specific developmental outcomes. The results will inform current discussion about the causes of poor arousal regulation, attentional difficulty, sleep deprivation, and their consequences for social, cognitive, and self-regulatory functioning in the preschool years.

OF
SHIFTWORK
Principal Investigator & Institution: Heitmann, Anneke; Circadian Technologies, Inc. 24 Hartwell Ave Lexington, Ma 024213103 Timing: Fiscal Year 2002; Project Start 01-MAY-1999; Project End 31-AUG-2004 Summary: (provided by applicant): A software system will be developed as a practical tool for accurately predicting alertness levels at work to help design bio-compatible work schedules and time the effective use of fatigue countermeasures. This software system can potentially benefit health and safety of a large portion of the working society. The core algorithm structure considers circadian and homeostatic aspects of sleep and alertness as well as time-on-task effects. The software system will use as input sleep and/or work patterns and individual characteristics (morningness/eveningness, habitual wake-up time) to generate a continuous alertness curve and statistical measures for work schedule evaluation. When the actual sleep pattern is not known, sleep will be predicted based on the work pattern. The algorithms of the modules for sleep and alertness prediction will be refined by optimization methods using error minimization techniques. The optimization process will use large training data sets on sleep and alertness patterns of shiftworkers with regular work schedules (to be collected during this project) and of workers with irregular work schedules (to be drawn from Circadian Technologies' extensive database). The predictive capability of the software system will be evaluated, using goodness-of-fit measures, by comparisons with Phase-I algorithms and by cross validations (using independent test data sets). PROPOSED COMMERCIAL APPLICATION: The progressive transition into a 24-hour society creates a large market for a software system for predicting alertness at work. This software system would be an attractive tool to design bio-compatible work schedules or to assess worker fatigue in accident investigations. The software system can also be used for worker training and public education regarding chronobiological and homeostatic aspects of sleep and sleepiness, and it can help increase awareness about the practical implications of fatigue at work.

Project Title: STATE DEPENDENT ASPECTS OF COGNITION Principal Investigator & Institution: Stickgold, Robert A.; Beth Israel Deaconess Medical Center St 1005 Boston, Ma 02215 Timing: Fiscal Year 2004; Project Start 01-SEP-1993; Project End 30-NOV-2008 Summary: (provided by applicant): The last 10 years have witnessed an almost explosive growth in our knowledge of the roles that sleep may play in learning and memory consolidation, but several major issues remain. Much of the problem is due to the complexity of the systems involved; there are multiple forms of memories, multiple steps in memory consolidation, and multiple stages of sleep which might contribute to these processes. It thus becomes necessary to first ask what kinds of memory are affected by sleep, and then to ask what stages of sleep and what steps of memory consolidation are involved. Evidence exists for both declarative and procedural memory systems being sleep dependent, and in some cases, distinct components of the consolidation process may be sleep-dependent. But relatively few findings have been validated by multiple groups, and several are only being presented for the first time in the Preliminary Results section of this application. We propose to address these three fundamental unresolved issues. We will attempt to show (1) that sleep mediates consolidation of a new declarative memory task (Mandarin language study), (2) that

slow wave sleep stabilizes and REM sleeps enhance perceptual learning, and (3) that sleep temporarily destabilizes motor skill learning as part of a process of sleep dependent consolidation. Confirming these hypotheses will significantly broaden our basic knowledge of the role of sleep in learning and memory consolidation. Western society has become a sleep deprived society, and this is especially true in the United States. There is a popular belief that the consequence of sleep deprivation is simply tiredness, that this can be overcome with effort or drugs, and that a good night's sleep on the weekend can completely reverse any deleterious effects of mid-week deprivation. Nowhere is this practice of "sleep bulimia," of weekly deprivation followed by weekend binge sleeping, more prevalent than on college campuses, although medical, public safety, and transportation personnel are also notoriously sleep deprived. All of these groups depend on continued education and learning for the effective performance of their tasks, and a clear understanding of exactly how sleep loss contributes to a failure of memory consolidation should provide important arguments to help counter this cultural drift towards less and less sleep. In addition, elucidation of the "sleep-memory connection" will enrich our understanding of the normal processes of learning and memory consolidation so critical to effectiveness in school and work, and help explain how sleep loss and sleep disorders lead to cognitive impairments in otherwise healthy individuals.

Project Title: STRESS EFFECTS ON SLEEP: INFLUENCE OF GENES AND GENDER Principal Investigator & Institution: Turek, Fred W.; Professor; Neurobiology and Physiology; Northwestern University 633 Clark St Evanston, Il 60208 Timing: Fiscal Year 2002; Project Start 30-SEP-1999; Project End 30-JUN-2004 Summary: The overall objectives of the proposed experiments in this application are to develop the mouse as an animal model for elucidating the genetic and molecular mechanisms for sleep regulation and to tet specific hypotheses regarding the importance of the genetic background and physiological state of both male and female mice in the regulation of sleep as well as the effects of stress on sleep. Stress can have major disruptive effects on sleep as well as the circadian clock, which itself plays a fundamental role in the regulation of sleep. Both genetic and environmental factors contribute to the regulation of sleep as well as to how the sleep and circadian clock systems of any one individual will be affected by stress. In the proposed studies, the effects in mice of acute stress, chronic mild stress, and short- term sleep deprivation on sleep and circadian rhythms will be determined. Mice with genetic differences will be studied. These genetic differences will be polygenic for some studies, or will test the roles of single candidate genes in others. In view of gender differences in both sleep and the response to stress that have been observed in other species, primarily in humans, the proposed studies will include females in different stages of the estrous cycle and after the age-related loss in cyclicity. An additional objective of this proposal is to develop and validate the use of a novel automated sleep analysis system in the mouse. It is anticipated that these studies will contribute to an understanding of the mechanisms whereby stress impacts sleep regulation. The results of these studies also will form a critical basis for use of the tools of mouse genetics to identify genetic and physiological factors which may influence sleep disruption. Such information is likely ultimately to lead to more effective interventions for humans who suffer from sleep disturbances due to stress or related factors, and may lead to new treatments for mental and physical disorders associated with sleep-wage abnormalities.

Sleep Deprivation
Project Title: THE EFFECT OF SEDATION ON RESTORATIVE SLEEP Principal Investigator & Institution: Tung, Avery; Anesthesia and Critical Care; University of Chicago 5801 S Ellis Ave Chicago, Il 60637 Timing: Fiscal Year 2002; Project Start 05-JUL-2001; Project End 30-JUN-2006 Summary: Sleep deprivation is common in the Intensive Care Unit (ICU) and can worsen outcomes. Recent introduction of propofol as an ICU sedative has allowed the widespread use of continuous sedation without delayed emergence. Such a strategy has been advocated to promote sleep. Although continuous sedation shares behavioral similarities with sleep, it is not known whether sedation effectively treats the sleepdeprived state. In principle, physiological and behavioral effects of sedation may either enhance or impair the ability of sleep to reverse the consequences of sleep deprivation. A period of sedation may itself alter the onset and intensity of sleep deprivation in the ICU. We seek to characterize the effects of continuous sedation on sleep with the longterm goal of understanding the neurobiological basis for the sleep-deprived state. The applicant has previously demonstrated in rats that prolonged sedation does not result in sleep deprivation, and that hypothalamic administration of propofol increases sleep. These findings suggest that a period of sedation is compatible with recovery from sleep deprivation, and imply that propofol may increase sleep by acting at a hypothalamic site. We hypothesize that the physiological consequences of sleep deprivation are reversed during prolonged use of continuous sedation. To test this hypothesis, we will 1) assess the ability of sedation to prevent sleep deprivation induced by environmental disruption, 2) compare the effects of continuous sedation with different agents on the restorative process associated with sleep, and 3) determine whether continuous sedation alters recovery sleep following sleep deprivation. We will acquire EEG/EMG and behavioral data in a rat model of sedation, sleep deprivation, and recovery. Using microdialysis, we will also measure extracellular adenosine concentrations in the basal forebrain before, during, and after sedation. Basal forebrain adenosine levels rise with prolonged wakefulness, and fall with recovery sleep. Little strategic importance has historically been assigned to preventing sleep deprivation in the ICU, partly because no proven method for treating sleep deprivation exists. Knowledge from this proposal will provide scientific insight into the relationships between anesthesia and sleep, and may lead to more effective clinical use of ICU sedatives.

Project Title: THE ROLE OF ADENOSINE IN WAKE/SLEEP TRANSITION Principal Investigator & Institution: Greene, Robert W.; Research Health Scientist; Psychiatry; University of Texas Sw Med Ctr/Dallas Dallas, Tx 753909105 Timing: Fiscal Year 2004; Project Start 16-JAN-2004; Project End 31-DEC-2008 Summary: (provided by applicant): Adenosine (AD) activation of A1 adenosine receptors (A1R) can inhibit neurons of the brainstem and basal forebrain cholinergic arousal centers and facilitate slow wave sleep as demonstrated by the somnogenic effect of local application of exogenous AD to these centers. This suggests the hypothesis that local increases in AD, correlated with neuronal activity, are sufficient to facilitate slow wave sleep (SWS). This hypothesis may be tested by induction of temporally and anatomically restricted A1R gene deletion using transgenes with selective promotion of the recombinase, Cre, and with an adeno-associated viral vector that expresses the recombinase, Cre. The Cre recombinase will catalyze the gene deletion in transgenic mice with loxP sequences flanking the target, the functionally essential A1R exon. The deletion is predicted to increase waking under baseline conditions and to dampen the

61
rebound sleep response to sleep deprivation. A physiologically relevant means of increasing A1R inhibition is by activation of NMDA receptors. This will be characterized in LDT using in vitro slice and whole cell voltage clamp recording techniques. AD cytoplasmic levels are in equilibrium with extracellular levels, and are, accordingly, of potential importance to extracellular, AD mediated inhibition and sleep/wake state modulation. The role of signal transduction processes in regulating the AD cytoplasmic levels will be investigated. The neuronal form of the major adenosine metabolizing enzyme, adenosine kinase (AK), will be characterized with regard to expression levels and localization at the RNA and protein level. The potential regulation of intracellular adenosine by protein phosphorylation/dephosphorylation of AK will be studied using a combination of molecular biological, protein biochemical, and neuropharmacological approaches. The state of phosphorylation of adenosine kinase across behavioral states and in response to sleep debt and rebound sleep will be assessed in whole animals (both rats and mice) and in brain slices. This may provide the requisite target cellular mechanism(s) for NMDA receptors and other potential modulators of extracellular AD.

Project Title: THE ROLE OF CYTOKINES IN SLEEPINESS AND SLEEP APNEA Principal Investigator & Institution: Vgontzas, Alexandros N.; Professor; Psychiatry; Pennsylvania State Univ Hershey Med Ctr 500 University Dr Hershey, Pa 17033 Timing: Fiscal Year 2002; Project Start 01-AUG-2000; Project End 31-JUL-2004 Summary: (applicant's abstract): Excessive daytime sleepiness (EDS) is a major public health concern, in part because individuals suffering from EDS often are not productive at work, are more susceptible to accidents, and generally are unable to function normally during the day. EDS is one of the major manifestations of individuals suffering from obstructive sleep apnea (OSA) and is frequently reported by obese individuals without sleep apnea. The mechanisms underlying EDS observed in both types of these individuals are not clear. We have recently demonstrated that the pro-inflammatory and fatigue-inducing cytokines, tumor necrosis factor-alpha (TNFalpha) and interleukin-6 (IL-6), assayed in single plasma samples, are elevated in subjects with disorders of EDS. In addition, in preliminary studies, we demonstrated that these two cytokines are elevated in obese, compared to lean subjects, and that both sleep disturbance and obesity contribute to the cytokine elevation. More recently, we showed that daytime plasma levels of IL-6 are elevated in experimentally-induced EDS by the use of sleep deprivation and that a good night's sleep is associated with decreased daytime levels in healthy young subjects. There is a large literature implicating several pro-inflammatory cytokines in the regulation of sleep in animals; however, cytokine research on sleep in humans has been very limited. The fundamental hypothesis to be tested by the proposed studies is that the pro-inflammatory cytokines, TNFalpha and IL-6, are associated with and may contribute to EDS. We will test this hypothesis by determining the circadian secretory patterns of TNFalpha and IL-6 in plasma obtained from subjects that exhibit EDS associated with OSA or obesity. Also, we will determine whether nighttime nasal CPAP reduces daytime plasma TNFalpha and IL-6 concentrations in sleep apneics. In addition, we will experimentally induce EDS in healthy young subjects by the use of total sleep deprivation or one week of sleep restriction, which mimics real life-situations, to determine the relationship between the pattern of daytime plasma TNFalpha and IL-6 concentrations and daytime sleepiness as measured objectively using MSLT. Finally, we will assess the effects of daytime napping, in healthy subjects, on post-nap sleepiness and TNFalpha and IL-6 secretion. In these studies, we will use a series of experimental techniques including nighttime polysomnography, MSLT,
62
Sleep Deprivation
computerized EEG, actigraphy, 24-hour blood sampling, 24-hour recording of core body temperature, and assays for TNFalpha and IL-6. These studies collectively will provide additional evidence for a role of TNFalpha and IL-6 in EDS and lay the foundation for the development of potential therapeutic interventions.

Project Title: TRAINING SCHEDULE EFFECTS ON SIMULATOR PERFORMANCE Principal Investigator & Institution: Cronin, John W.; Brigham and Women's Hospital 75 Francis Street Boston, Ma 02115 Timing: Fiscal Year 2003; Project Start 30-SEP-2003; Project End 30-JUN-2005 Summary: (provided by the applicant): Daily variations in physiologic and cognitive functions in human beings are driven by an endogenous circadian pacemaker. Human performance is further governed by the relative amounts of both chronic and acute sleep deprivation. Medical trainees, providing a significant amount of primary medical care in the U.S., are vulnerable to impaired performance and learning by virtue of schedules that demand long work hours. Surgical trainees, who are exposed to perhaps the greatest sleep deprivation and who are asked to perform critical tasks at adverse circadian phases, are a particularly important group. While much public policy debate has led to the mandate of reduced work hours, insufficient work has been done to determine the optimal work hours necessary to preserve top performance on critical tasks while preserving the educational opportunities for trainees. In June, 2003, ACGME work hour limitations loosely limit work hours to less than 80 hours a week and to no more than 24 hours of direct patient care. This proposal will attempt to work within that framework by testing surgical trainees on the following three schedules: 8-10 hour shift; 12-16 hour shift; and an on-call shift of 24-30 hours. Sleep will be characterized by actigraphy, diary self report, salivary cortisol assays and EEG recordings. Performance under these conditions will be measured using the MIST-VR laproscopic surgical simulator. Six critical tasks will be assessed for errors, efficiency and time on task and compared across the three schedules. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: VACHT EXPRESSION ACROSS SLEEP-WAKEFULNESS Principal Investigator & Institution: Greco, Mary Ann K.; Project Leader; Sri International 333 Ravenswood Ave Menlo Park, Ca 94025 Timing: Fiscal Year 2003; Project Start 15-JUN-2003; Project End 31-MAY-2007 Summary: (provided by applicant): Over 70 million people in the U.S. are estimated to suffer from alterations in sleep-wakefulness. Existing therapies are of limited utility in treating these disorders. The difficulties in devising more effective treatments stem, in large part, from the fact that there is no one sleep center in the brain. As a result, the biological function(s) of sleep have not been elucidated. The neuronal circuitry underlying sleep-wakefulness is beginning to be understood. The intracellular events associated with the activity of these neurons across sleep-wakefulness, however, are not well defined. Understanding cellular mechanisms that occur during sleep is key to the identification of biological function(s). Acetylcholine (ACh) is associated with sleepwakefulness. Preliminary results examining the ACh synthesis enzyme, choline acetyltransferase (ChAT) are consistent with the hypothesis that sleep may play a role in maintaining neurotransmitter levels that are depleted during waking via changes in mRNA during sleep. The vesicular acetylcholine transporter (VAChT) performs the essential function of packaging nascent acetylcholine into vesicles. The gene encoding

yacht lies within the gene encoding chat in all species examined, an extremely rare mammalian genomic organization. Preliminary studies suggest that chat and vacht mRNA levels are differentially expressed during sleep. In these studies, we focus first on delineating VAChT expression. In the first specific aim, we test the hypothesis that vacht mRNA and protein vary across individual sleep-wake bouts (i.e., waking, SWS and REM sleep) occurring over a 24h period. Preliminary studies of vacht mRNA suggest that it is higher during waking than during sleep. The second specific aim tests the hypothesis that mRNA and protein are associated with wakefulness. Initial results show vacht mRNA did not vary following six hours of sleep deprivation compared to controls. Specific aims 3 and 4 focus on comparisons of vacht and chat mRNAs, given the genomic organization of the genes and preliminary results that show that vacht mRNA contrasts with chat mRNA expression. Specific aim 3 tests the hypothesis that chat and vacht mRNAs are differentially expressed during sleep, while specific aim 4 tests the hypothesis that vacht mRNA subtypes are differentially expressed in response to sleep-wakefulness. Identification of these patterns of expression are key to understanding cellular mechanisms underlying sleep and wakefulness. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: WAKE/SLEEP DEVELOPMENT AND DEPRESSIVE SUBSTRATES Principal Investigator & Institution: Feng, Pingfu; Assistant Professor; Medicine; Case Western Reserve University 10900 Euclid Ave Cleveland, Oh 44106 Timing: Fiscal Year 2004; Project Start 16-DEC-2003; Project End 30-NOV-2006 Summary: (provided by applicant): Our long-term goal is to determine the role for neonatal rapid eye movement (REM) sleep in normal growth and development as well as in the determination of mood and sleep-wake behaviors in the adult. This is relevant to the neurobiologic and genetic mechanisms underlying depression. Extensive literature, including our previous studies, supports our hypothesis that neonatal REM sleep deprivation (RSD) alters the balance of development of wake promoting consequences and creates a disinhibited REM generation system that affects behavior and mood. Previous findings show that a rat with neonatal exposure to clomipramine has more REM sleep as an adult and our recent findings reveal that neonatal treatment with clomipramine reduce the brain levels of orexin B and/or delay the development of orexinergic neurons, which are identified as wake promotion neurons. This data supports a novel idea that neonatal RSD produces behavioral consequences by altering orexinergic as well as monoaminergic systems, then acting through MAPK signaltransduction pathways in the frontal cortex. We propose to test this hypothesis by examining the molecular changes occurring with wake/REM sleep alterations in two neonatal RSD models. One is made by treatment with REM sleep suppressant clomipramine and the other is made by non-pharmacological RSD. We will examine neuronal and molecular markers in the adult, the ontogenetic response of wake promoting related molecules to neonatal RSD, and interventions to reverse the effect of neonatal RSD. We will also examine the behavioral and molecular effect of the treatment by modulating wake regulation with either drug or non-drug methods and comparing with classic antidepressant. Results showing the impact of neonatal RSD on signaling pathways and on chronic changes in monoaminergic functions is relevant to a number of human illness, including depression and schizophrenia in the adult. Identifying modifiers of the adult behavioral alteration may provide insight into alternative countermeasures for these common illnesses. The present research plan addresses fundamental needs towards developing animal models of depression, the impact of sleep on the plasticity of systems regulating sleep and mood, and understanding the
64

mechanisms of pharmacologic interventions. This proposal is also involved in a test of orexinergic effect on behavior and molecular alteration that may open a new scope toward the discovery of new antidepressant drugs. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: WORKING MEMORY IN OBSTRUCTIVE SLEEP APNEA-AN FMRI STUDY Principal Investigator & Institution: Thomas, Robert J.; Beth Israel Deaconess Medical Center St 1005 Boston, Ma 02215 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-JUL-2007 Summary: (provided by applicant): Obstructive sleep apnea (OSA) is associated with abnormalities of higher order executive cognitive functions. The precise neuroanatomical localization of these deficits is unknown. The physiological correlates of executive cognitive dysfunction are poorly defined, and recovery following therapy may be incomplete. This project proposes the novel use of a neuroimaging technology, functional magnetic resonance imaging (fMRI), and precise neurobehavioral protocols, to localize the neuroanatomical site of dysfunction. Additional protocols will isolate specific physiological correlates of these neurocognitive abnormalities such as sleep fragmentation, sleep deprivation, and nocturnal oxygen desaturation and will relate them to altered regional cortical function. We will examine the cause of incomplete recovery of executive function while on therapy with nasal positive airway pressure. Working memory is a brain system that provides temporary storage and manipulation of information necessary to execute complex cognitive tasks, and it contributes to several executive functions. The n-back paradigm is an extensively used probe of working memory in MU studies, and is normally associated with activation of dorsolateral prefrontal cortex (DLPFC), anterior cingulate and posterior parietal cortex. We have adapted this task at the 2- back level of difficulty for use in OSA patients. Our preliminary data suggest a reversible (with treatment) reduction of working memory capacity in OSA patients that may be secondary to selective dysfunction in the DLPFC, relative to other nodes in the executive control network. Based on this data we hypothesize that: 1) Patients with OSA have reduced activation of the DLPFC, relative to posterior parietal cortex during tests of working memory. 2) Sleep deprivation or fragmentation but not nocturnal hypoxia disrupts working memory in normal subjects. 3). Post-treatment residual abnormalities are caused by persisting sleep fragmentation, not prior hypoxic exposure. The P.I. has training in general medicine, neurology, sleep disorders and functional neuroimaging. The proposed projects will be performed under the direct guidance of experts in sleep disorders, cognitive neuroscience, and fMRI within the Harvard system. The relevant research environment is particularly rich at the participating institutions-basic and applied neurobiology of sleep, clinical sleep disorders, behavioral neurology, and fMRI. The career development plan will include training in MRI physics, applied MRI, statistics and research methodology, ethics, planning of clinical research, and cognitive neuroscience. The immediate career goal is to acquire the necessary skills for applied clinical fMRI and determine the functional neurocircuitry of the localization, etiology and recovery of reduced working memory capacity in patients with OSA using the 2-back task paradigm. The longterm career goal is to develop a model of the function of sleep by demonstrating the functional consequences of sleep disruption in conditions such as depression, age-related memory dysfunction, and attention deficit hyperactivity disorder.

CHAPTER 2. NUTRITION AND SLEEP DEPRIVATION Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and sleep deprivation.
Finding Nutrition Studies on Sleep Deprivation The National Institutes of Health’s Office of Dietary Supplements (ODS) offers a searchable bibliographic database called the IBIDS (International Bibliographic Information on Dietary Supplements; National Institutes of Health, Building 31, Room 1B29, 31 Center Drive, MSC 2086, Bethesda, Maryland 20892-2086, Tel: 301-435-2920, Fax: 301-480-1845, E-mail:
[email protected]). The IBIDS contains over 460,000 scientific citations and summaries about dietary supplements and nutrition as well as references to published international, scientific literature on dietary supplements such as vitamins, minerals, and botanicals.4 The IBIDS includes references and citations to both human and animal research studies. As a service of the ODS, access to the IBIDS database is available free of charge at the following Web address: http://ods.od.nih.gov/databases/ibids.html. After entering the search area, you have three choices: (1) IBIDS Consumer Database, (2) Full IBIDS Database, or (3) Peer Reviewed Citations Only. Now that you have selected a database, click on the “Advanced” tab. An advanced search allows you to retrieve up to 100 fully explained references in a comprehensive format. Type “sleep deprivation” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.

Adapted from http://ods.od.nih.gov. IBIDS is produced by the Office of Dietary Supplements (ODS) at the National Institutes of Health to assist the public, healthcare providers, educators, and researchers in locating credible, scientific information on dietary supplements. IBIDS was developed and will be maintained through an interagency partnership with the Food and Nutrition Information Center of the National Agricultural Library, U.S. Department of Agriculture.

CHAPTER 5. CLINICAL TRIALS AND SLEEP DEPRIVATION Overview In this chapter, we will show you how to keep informed of the latest clinical trials concerning sleep deprivation.
Recent Trials on Sleep Deprivation The following is a list of recent trials dedicated to sleep deprivation.5 Further information on a trial is available at the Web site indicated. •
Activating Effects of Sleep Deprivation on Synchronized MEG-EEG Recordings of Epilepsy Patients with Non-Diagnostic EEG Condition(s): Epilepsy Study Status: This study is currently recruiting patients. Sponsor(s): National Institute of Neurological Disorders and Stroke (NINDS) Purpose - Excerpt: This study will evaluate how the state of being completely deprived of sleep has an effect on recordings of magnetoencephalography (MEG) and electroencephalography (EEG), in relation to how alert someone is and how sleepy someone perceives himself or herself to be. EEG measures electronic potential differences on the scalp. On the other hand, MEG is a non-invasive technique for recording the activity of neurons in the brain, through recording of magnetic fields caused by synchronized neural currents. It has the ability to detect seizures. Because magnetic signals of the brain vary, this technique must balance two key problems: weakness of the signal and strength of the noise. The EEG is sensitive to extra-cellular volume currents, whereas the MEG primarily registers intra-cellular currents. Because electrical fields are quite dependent on the conductive properties of the tissues, and magnetic fields are significantly less distorted by tissue, the MEG has better spatial resolution. There is a great deal of evidence that EEG and MEG provide complementary data about underlying currents of ions. The complex relationship of sleep and epilepsy is well known. Sleep has been used for many years as a powerful EEG activator. Many researchers have supported the hypothesis that there is a specific activating effect of

Sleep Deprivation
sleep deprivation on epileptic discharges. Sleep deprivation is defined as a sleepless state of longer than 24 hours. The increased use of MEG in diagnosis could improve the procedure for evaluating patients before surgery for epilepsy, by making invasive studies less necessary. Patients 18 years of age or older, with a diagnosis of epilepsy and with a documented last routine EEG (at least 2 weeks earlier) and routine EEG on the day of a baseline MEG-EEG without interictal epileptiform discharges (IEDs) may be eligible for this study. Participants will be rated according to the Epworth, Stanford, and Karolinska Sleepiness Scales, to determine their subjective sleepiness. They will be randomly assigned to stay awake all night or sleep in the hospital overnight. That is, a sleep deprivation and non-sleep deprivation synchronized MEG-EEG recording will be performed in random order. Then the sequence of sleep deprivation and non-sleep deprivation will be reversed within 14 to 21 days. During the recordings, the patient will either sit or lie with his or her head in a helmet covering the entire head, with openings for the eyes and ears. Brain magnetic fields will be recorded with a 275-channel OMEGA system. Throughout the session, visual and two-way audio communication will be maintained with the patient. Recording sessions will last 90 to 180 minutes, with the patient allowed to take breaks after at least 10 minutes in a scanner. Attempts will be made to encourage patients to stay awake and sleep for about the same amount of time during each recording, to acquire comparable amounts of sleep and awake recordings.

Combined Behavioral/Pharmacological Therapy for Insomnia Condition(s): Sleep Initiation and Maintenance Disorders; Sleep Deprivation Study Status: This study is currently recruiting patients. Sponsor(s): National Institute of Mental Health (NIMH) Purpose - Excerpt: The purpose of this study is to determine how sleeping pills can be combined with nondrug treatments to maximize the benefits of therapy for insomnia. Study Type: Interventional Contact(s): see Web site below Web Site: http://clinicaltrials.gov/ct/show/NCT00044629
Keeping Current on Clinical Trials The U.S. National Institutes of Health, through the National Library of Medicine, has developed ClinicalTrials.gov to provide current information about clinical research across the broadest number of diseases and conditions. The site was launched in February 2000 and currently contains approximately 5,700 clinical studies in over 59,000 locations worldwide, with most studies being conducted in the United States. ClinicalTrials.gov receives about 2 million hits per month and hosts approximately 5,400 visitors daily. To access this database, simply go to the Web site at http://www.clinicaltrials.gov/ and search by “sleep deprivation” (or synonyms).
Clinical Trials 129
While ClinicalTrials.gov is the most comprehensive listing of NIH-supported clinical trials available, not all trials are in the database.

CHAPTER 6. PATENTS ON SLEEP DEPRIVATION Overview Patents can be physical innovations (e.g. chemicals, pharmaceuticals, medical equipment) or processes (e.g. treatments or diagnostic procedures). The United States Patent and Trademark Office defines a patent as a grant of a property right to the inventor, issued by the Patent and Trademark Office.6 Patents, therefore, are intellectual property. For the United States, the term of a new patent is 20 years from the date when the patent application was filed. If the inventor wishes to receive economic benefits, it is likely that the invention will become commercially available within 20 years of the initial filing. It is important to understand, therefore, that an inventor’s patent does not indicate that a product or service is or will be commercially available. The patent implies only that the inventor has “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States. While this relates to U.S. patents, similar rules govern foreign patents. In this chapter, we show you how to locate information on patents and their inventors. If you find a patent that is particularly interesting to you, contact the inventor or the assignee for further information. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical patents that use the generic term “sleep deprivation” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on sleep deprivation, we have not necessarily excluded nonmedical patents in this bibliography.
Patents on Sleep Deprivation By performing a patent search focusing on sleep deprivation, you can obtain information such as the title of the invention, the names of the inventor(s), the assignee(s) or the company that owns or controls the patent, a short abstract that summarizes the patent, and a few excerpts from the description of the patent. The abstract of a patent tends to be more technical in nature, while the description is often written for the public. Full patent descriptions contain much more information than is presented here (e.g. claims, references, figures, diagrams, etc.). We will tell you how to obtain this information later in the chapter. 6Adapted

(110 Hundreds Rd., Wellesley Farms, MA 02181) Assignee(s): None Reported Patent Number: 5,433,223 Date filed: November 18, 1993 Abstract: A method enables the prediction of the likely alertness level of an individual at a given point in time based upon the analysis of certain biological and other parameters associated with the individual subject including, circadian phase of the biological clock, accumulated acute or chronic sleep deprivation, shift commencement and termination time, time of last sleep, environmental light, etc. Among other advantages, the method facilitates the creation of bio-compatible schedules for shift workers by providing an accurate model of the likely alertness level of the individual on a specific schedule. Excerpt(s): This invention relates to the prediction of the alertness level of an individual and the suitability of work schedules therefor, especially as related to a shift worker. In the modern world, many organizations rely on around-the-clock operations. Airlines, railroads, nuclear power plants, to name just a few, are entities where safety is of great concern and where it is necessary to ensure staffing twenty-four hours a day. With the advent of around-the-clock operations came the need for the development of shift work schedules as a way to address the requirement for staffing at all hours. It soon became apparent, however, that shift work brings with it its own set of problems. Shift workers often complain of inability to obtain adequate sleep during their off-hours, chronic sleep deprivation, reduced alertness, and even falling asleep on the job, as being realities of the around-the-clock workplace.

sleep by administration of fatty acid primary amides, including cis-9,10octadecenoamide, and to a method for assaying sleep deprivation by analyzing cerebrospinal fluid with respect to fatty acid primary amides, including cis-9,10octadecenoamide. Sleep is a natural, periodic behavioral state during which the body rests itself and its physiological powers are restored. It is characterized by a loss of reactivity to the environment. During sleep, certain physiological processes of both the body and the brain function differently than they do during alert wakefulness. Normal sleep consists of at least two quite different behavioral states: synchronized sleep, during which the electroencephalogram consists of slow waves of high amplitude, and desynchronized sleep (DS) or activated sleep characterized by rapid eye movements (REM sleep), in which the electroencephalogram pattern is characterized by waves of high frequency and low amplitude. Synchronized sleep is further characterized by slow and regular respiration, by relatively constant heart rate and blood pressure, and by a predominance of delta waves. Synchronized sleep usually consists of four stages, followed by a period of activated sleep. Each cycle lasts between 80 and 120 minutes. In contrast, desynchronized sleep is further characterized by irregular heart rate and respiration, periods of involuntary muscular jerks and movements, and a higher threshold for arousal. Periods of desynchronized sleep last from 5-20 minutes and occur at about 90 minute intervals during a normal night's sleep. Sleep deprivation can arise from any of a variety of sleep disorders and environmental factors. Insomnia is a common sleep disorder in which the individual is unable to initiate or maintain sleep. In the prior art, there is no known pharmacological method for inducing the full sleep cycle and no known method using biological samples for assaying sleep deprivation.

Patent Applications on Sleep Deprivation As of December 2000, U.S. patent applications are open to public viewing.7 Applications are patent requests which have yet to be granted. (The process to achieve a patent can take several years.) The following patent applications have been filed since December 2000 relating to sleep deprivation: •
Canine authentic intrauterine sound device Inventor(s): Coats, Genelle; (Pleasanton, CA) Correspondence: Genelle Coats; 774 Neal Place; Pleasanton; CA; 94566; US Patent Application Number: 20030055312 Date filed: September 17, 2001 Abstract: The Canine Authentic Intrauterine Sound Device (CAISD) provides a single, compact, easy to use device for dog owners. The CAISD will provide original, familiar, authentic canine intrauterine sounds to relieve the stress of separation for the new puppy and/or the stress of a canine that has experienced some kind of trauma. The CAISD, equipped with motion and sound sensitivity, will minimize sleep deprivation for both puppy and owner alike, thereby allowing the young new canine the opportunity to adapt to its new environment in as natural a manner as possible.

Sleep Deprivation
Excerpt(s): This invention relates to the use of canine authentic intrauterine sounds as a stress reducer for new puppies. This original and novel canine authentic intrauterine sound device would replace the most widely suggested possible resolution to a howling/crying new puppy, the ticking clock and hot water bottle. The idea for a Canine Authentic Intrauterine Sound Device came to me while at my niece's baby shower. I overheard the young women in attendance discussing the use of sounds from the mother's womb that would calm a baby during sleeptime. I thought surely this could work for puppies.

Method for treating effects of sleep deprivation and jet lag with NADPH and NADPH Inventor(s): Birkmayer, Joerg G. D.; (Vienna, AT) Correspondence: Kenyon & Kenyon; One Broadway; New York; NY; 10004; US Patent Application Number: 20030021772 Date filed: June 29, 2001 Abstract: A method for alleviating the symptoms of sleep deprivation or jet lag wherein the reduced form of nicotinamide adenine dinucleotide (NADH) or the reduced form of nicotinamide adenine dinucleotide phosphate (NADPH) or physiologically compatible salts or derivatives of NADH and/or NADPH are administered to a human being suffering from the effects. Human beings so treated exhibit an abatement of these effects, such as, for example, decreased attentiveness, decreased ability to concentrate, decreased reaction time, decreased alertness, and decreased productivity and efficiency. Excerpt(s): The present invention relates to a pharmaceutical and a method for treating the effects of sleep deprivation generally, and jet lag specifically. More particularly, the present invention relates to the use of reduced forms of nicotinamide-adeninedinucleotide (NADH) or nicotinamide-adenine-dinucleotide phosphate (NADPH), or physiologically acceptable salts or derivatives thereof, in treating the adverse effects of sleep deprivation and jet lag. Every human being needs a certain amount of sleep each day in order to lead a healthy, productive life. Sleep deprivation is the condition of being deprived of this needed sleep, resulting in adverse effects on an individual, such as, for example, decreased attentiveness, decreased ability to concentrate, decreased reaction time, decreased alertness, and decreased productivity and efficiency. Sleep deprivation can be caused by, for example, sleep disorders, such as insomnia or obstructive sleep apnea, medical illnesses, shifting work schedules, depression, or flying across time zones. Jet lag is a constellation of symptoms that occur in a human being after flying across time zones. It affects a large number of travelers and aircrew. These symptoms include: general malaise, disruption of or deprivation of sleep, gastrointestinal distress, and memory loss. In M. R. Rosekind et al., Fatigue in Operational Settings: Examples from the Aviation Environment, Hum. Factors (1994), 36(2):327-38, the authors estimate that jet lag can degrade decision-making abilities, communication and memory by 30% to 70%. The disruption of the body's entrainment of internal 24-hour cycles of temperature, sleep initiation and other activities to the daylight cycle is believed to be the trigger for jet lag. See G. Copinschi et al., Pathophysiology of Human Circadian Rhythms, Novartis Found. Symp. 2000, 227:14357; F. W. Turek et al., Entrainment of the circadian activity rhythm to the light-dark cycle can be altered by a short-acting benzodiazepine, triazolam, J. Biol. Rhythms (1987), 2(4):249-260.

often is required to perform at a high functional level upon reaching their destination. Furthermore, the problems of jet lag have been compounded in recent years because business travelers are taking more international trips and staying fewer days at their destination.

System and method for evaluating task effectiveness based on sleep pattern Inventor(s): Hursh, Steven Rawlings; (Joppa, MD) Correspondence: Banner & Witcoff; 1001 G Street N W; Suite 1100; Washington; DC; 20001; US Patent Application Number: 20030013943 Date filed: July 6, 2001 Abstract: A method for evaluating the effectiveness of a person to perform a task based on his/her previous or predicted sleep activity is provided. The method can be used to predict changes in task effectiveness at any time of day, based upon numerous patterns of sleep and activity, either experienced or planned for the future. The method take into account progressive increases in sleep deprivation, the effects of the time of day on performance, and changes in the time when a person sleeps and works. The method also accounts for the quality of a sleep interval and a person's sleep inertia, the temporary slowing of performance immediately after awakening. The method is homeostatic. Gradual decreases in sleep debt decrease sleep intensity. Progressive increases in sleep debt produced by extended periods of less than optimal levels of sleep lead to increased sleep intensity. As a result the method can predict the normal decline in sleep intensity during the sleep period and the normal equilibrium of performance under less than optimal schedules of sleep. Excerpt(s): The present invention relates to a system and method for evaluating the effectiveness of a person to perform a task based on his/her preceding or predicted sleep pattern. More particularly, the present invention relates to a system and method for evaluating task effectiveness based on preceding or predicted sleep pattern using calculations that take into account circadian oscillators, a sleep reservoir, sleep intensity, performance use, sleep debt, interruptions to sleep, sleep inertia, and the demands of the task to be performed. Numerous studies have been conducted relating to the analysis of sleep, alertness, and performance. One study is by Jewett and Kronauer, entitled "Interactive Mathematical Models of Subjective Alertness and Cognitive Throughput in Humans," J. Biological Rhythms, 1999; 14(6): pages 588-597. The Jewett and Kronauer model (JK model hereafter) uses arbitrary units and then scales the result from 1 to 0 to fit the actual data, scaled from maximum to minimum. Consequently, the JK model does not make an independent prediction of performance without knowing the range of the results. The JK model makes no provision for predicting the detrimental effects of sleep fragmentation and multiple interruptions in sleep. The JK model uses an oscillator with a large number of arbitrary parameters (van der Pol oscillator) to predict the asymmetrical cycle of performance around the clock. The JK model cannot adjust the phase of the circadian rhythm to reflect shift-work or transmeridian travel without detailed information about ambient light levels. Furthermore, the JK model cannot predict variations in any relevant aspect of operator performance that is of interest to the user. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Summary: More than 700,000 Americans have interstitial cystitis (IC), a condition that includes symptoms of recurring bladder pain and discomfort on urination. This chapter on support for the IC patient is from a self care book designed to empower readers by simplifying the diagnostic and treatment process for IC. The primary object of the book is to build a framework for delivering proper care to the IC patient. This chapter is written by Vicki Ratner, M.D., the founder and president of the Interstitial Cystitis Association (ICA). The author briefly reviews the history of IC, noting that patients often went years before diagnosis and were forced into a situation of educating themselves and their physicians about the disease. The author then summarizes the history of the ICA and its present role as a support network for patients. The author emphasizes the need for support in dealing with a chronic disease that can disrupt every aspect of one's life. Severe pain, sleep deprivation, and frequent trips to the bathroom can make it difficult to maintain relationships, hold a job, or participate in social activities. Support services can make a critical difference in coping with IC. The chapter concludes with the contact information for the ICA.

Book Sales, 334 Speech and Hearing Center, University of Iowa, Iowa City, IA 52242. Website: www.ncvs.org. PRICE: $75.00 plus shipping and handling. ISBN: 0874141230. Summary: This chapter on the immune system is from a multi-volume text that brings a biopsychosocial approach to the study of the voice. The authors use the phrase 'bodyminds' to describe the interrelationship of perception, memory, learning, behavior, and health, as they combine to affect all environmental interactions, adaptations, and learning. The books are written for teachers, voice professionals, people who use their voices on an avocational basis, and interested members of the general public. This chapter describes the function of the immune system and how the vocal abilities can be limited by immune system reactions. Topics include bacterial, viral and fungal infections of the respiratory tract; allergies; and cancer. Inflammation that relates to the voice can occur in response to infective pathogens and their products, allergenic substances and their products, toxic or irritant substances (gasses, acids, particles) that are deposited or released onto the mucosal tissues of the respiratory tract, relatively intense impact and shearing forces during extensive or vigorous voicing, or imbalances in immune endocrine chemistry due to stress or sleep deprivation. When the vocal folds are inflamed (due to any of these reasons) and hoarseness is present, they are more vulnerable to the impact and shearing stresses that come from misuse or overuse. Extensive, vigorous, and inefficient voice use can more easily create serious voice disorders when preexisting tissue inflammation is present. 45 references.

Coffee Break: Tutorials for Biologists17 Coffee Break is a general healthcare site that takes a scientific view of the news and covers recent breakthroughs in biology that may one day assist physicians in developing treatments. Here you will find a collection of short reports on recent biological discoveries. Each report incorporates interactive tutorials that demonstrate how bioinformatics tools are used as a part of the research process. Currently, all Coffee Breaks are written by NCBI staff.18 Each report is about 400 words and is usually based on a discovery reported in one or more articles from recently published, peer-reviewed literature.19 This site has new articles every few weeks, so it can be considered an online magazine of sorts. It is intended for general background information. You can access the Coffee Break Web site at the following hyperlink: http://www.ncbi.nlm.nih.gov/Coffeebreak/.
Other Commercial Databases In addition to resources maintained by official agencies, other databases exist that are commercial ventures addressing medical professionals. Here are some examples that may interest you: •
CliniWeb International: Index and table of contents to selected clinical information on the Internet; see http://www.ohsu.edu/cliniweb/.
•
Medical World Search: Searches full text from thousands of selected medical sites on the Internet; see http://www.mwsearch.com/.
17 Adapted 18
from http://www.ncbi.nlm.nih.gov/Coffeebreak/Archive/FAQ.html.
The figure that accompanies each article is frequently supplied by an expert external to NCBI, in which case the source of the figure is cited. The result is an interactive tutorial that tells a biological story. 19 After a brief introduction that sets the work described into a broader context, the report focuses on how a molecular understanding can provide explanations of observed biology and lead to therapies for diseases. Each vignette is accompanied by a figure and hypertext links that lead to a series of pages that interactively show how NCBI tools and resources are used in the research process.

APPENDIX B. PATIENT RESOURCES Overview Official agencies, as well as federally funded institutions supported by national grants, frequently publish a variety of guidelines written with the patient in mind. These are typically called “Fact Sheets” or “Guidelines.” They can take the form of a brochure, information kit, pamphlet, or flyer. Often they are only a few pages in length. Since new guidelines on sleep deprivation can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internet-based services that post them.
Patient Guideline Sources The remainder of this chapter directs you to sources which either publish or can help you find additional guidelines on topics related to sleep deprivation. Due to space limitations, these sources are listed in a concise manner. Do not hesitate to consult the following sources by either using the Internet hyperlink provided, or, in cases where the contact information is provided, contacting the publisher or author directly. The National Institutes of Health The NIH gateway to patients is located at http://health.nih.gov/. From this site, you can search across various sources and institutes, a number of which are summarized below. Topic Pages: MEDLINEplus The National Library of Medicine has created a vast and patient-oriented healthcare information portal called MEDLINEplus. Within this Internet-based system are “health topic pages” which list links to available materials relevant to sleep deprivation. To access this system, log on to http://www.nlm.nih.gov/medlineplus/healthtopics.html. From there you can either search using the alphabetical index or browse by broad topic areas. Recently, MEDLINEplus listed the following when searched for “sleep deprivation”:

You may also choose to use the search utility provided by MEDLINEplus at the following Web address: http://www.nlm.nih.gov/medlineplus/. Simply type a keyword into the search box and click “Search.” This utility is similar to the NIH search utility, with the exception that it only includes materials that are linked within the MEDLINEplus system (mostly patient-oriented information). It also has the disadvantage of generating unstructured results. We recommend, therefore, that you use this method only if you have a very targeted search. The Combined Health Information Database (CHID) CHID Online is a reference tool that maintains a database directory of thousands of journal articles and patient education guidelines on sleep deprivation. CHID offers summaries that describe the guidelines available, including contact information and pricing. CHID’s general Web site is http://chid.nih.gov/. To search this database, go to http://chid.nih.gov/detail/detail.html. In particular, you can use the advanced search options to look up pamphlets, reports, brochures, and information kits. The following was recently posted in this archive: •

Summary: This fact sheet for people with fibromyalgia discusses the affected population, symptoms, diagnosis, and treatment of this common disorder. Three to six million Americans may have the symptoms of fibromyalgia, such as widespread pain and tenderness, particularly around the affected joints and muscles. Fibromyalgia pain is influenced by many intrinsic factors and tends to fluctuate, but it is never completely relieved. It is usually most severe in the morning and late evening, and it is accompanied by diffuse stiffness. Other complaints include swollen joints, fatigue, sleep deprivation, anxiety, tension headaches, neurologic symptoms, irritable bowel syndrome, and dry eyes and mouth. Diagnosis is based on finding tender points in the presence of widespread pain, but other inflammatory conditions that present with similar symptoms must be ruled out. Various treatment approaches have been tried, including eliminating contributing factors, using nonsteroidal anti-inflammatory drugs, exercising, and providing the body with adequate nourishment. The fact sheet also explains what autoimmunity is and outlines the activities of the American Autoimmune Related Diseases Association. •

[email protected]. PRICE: Single copy free. Summary: This fact sheet from the Royal National Institute for Deaf People (RNID) discusses sleep and tinnitus (ringing or other noises in the ears), describes the impact of sleep deprivation, and notes how the symptoms of sleep deprivation are similar to those felt by people who are dealing with tinnitus. The fact sheet discusses the relationship these two conditions. Medical professionals disagree about whether it is tinnitus or the tension, anxiety and depression associated with it that disturb the sleeper. Other topics covered include the use of sedatives or tranquilizers, sleep assessment techniques, relaxation methods to help with sleep, the different types of sleep disturbance, the 'vicious cycle' of sleep deprivation and worry about sleep deprivation, changing sleep patterns with age, and tips for things to try and to avoid in order to maximize sleep habits. One sidebar summarizes six steps to sound sleep. The fact sheet mentions a few books and articles that may offer additional information. 4 references. The NIH Search Utility
The NIH search utility allows you to search for documents on over 100 selected Web sites that comprise the NIH-WEB-SPACE. Each of these servers is “crawled” and indexed on an ongoing basis. Your search will produce a list of various documents, all of which will relate in some way to sleep deprivation. The drawbacks of this approach are that the information is not organized by theme and that the references are often a mix of information for professionals and patients. Nevertheless, a large number of the listed Web sites provide useful background information. We can only recommend this route, therefore, for relatively rare or specific disorders, or when using highly targeted searches. To use the NIH search utility, visit the following Web page: http://search.nih.gov/index.html.

Finding Associations There are several Internet directories that provide lists of medical associations with information on or resources relating to sleep deprivation. By consulting all of associations listed in this chapter, you will have nearly exhausted all sources for patient associations concerned with sleep deprivation. The National Health Information Center (NHIC) The National Health Information Center (NHIC) offers a free referral service to help people find organizations that provide information about sleep deprivation. For more information, see the NHIC’s Web site at http://www.health.gov/NHIC/ or contact an information specialist by calling 1-800-336-4797. Directory of Health Organizations The Directory of Health Organizations, provided by the National Library of Medicine Specialized Information Services, is a comprehensive source of information on associations. The Directory of Health Organizations database can be accessed via the Internet at http://www.sis.nlm.nih.gov/Dir/DirMain.html. It is composed of two parts: DIRLINE and Health Hotlines. The DIRLINE database comprises some 10,000 records of organizations, research centers, and government institutes and associations that primarily focus on health and biomedicine. To access DIRLINE directly, go to the following Web site: http://dirline.nlm.nih.gov/. Simply type in “sleep deprivation” (or a synonym), and you will receive information on all relevant organizations listed in the database. Health Hotlines directs you to toll-free numbers to over 300 organizations. You can access this database directly at http://www.sis.nlm.nih.gov/hotlines/. On this page, you are given the option to search by keyword or by browsing the subject list. When you have received

your search results, click on the name of the organization for its description and contact information. The Combined Health Information Database Another comprehensive source of information on healthcare associations is the Combined Health Information Database. Using the “Detailed Search” option, you will need to limit your search to “Organizations” and “sleep deprivation”. Type the following hyperlink into your Web browser: http://chid.nih.gov/detail/detail.html. To find associations, use the drop boxes at the bottom of the search page where “You may refine your search by.” For publication date, select “All Years.” Then, select your preferred language and the format option “Organization Resource Sheet.” Type “sleep deprivation” (or synonyms) into the “For these words:” box. You should check back periodically with this database since it is updated every three months. The National Organization for Rare Disorders, Inc. The National Organization for Rare Disorders, Inc. has prepared a Web site that provides, at no charge, lists of associations organized by health topic. You can access this database at the following Web site: http://www.rarediseases.org/search/orgsearch.html. Type “sleep deprivation” (or a synonym) into the search box, and click “Submit Query.”

APPENDIX C. FINDING MEDICAL LIBRARIES Overview In this Appendix, we show you how to quickly find a medical library in your area.
Preparation Your local public library and medical libraries have interlibrary loan programs with the National Library of Medicine (NLM), one of the largest medical collections in the world. According to the NLM, most of the literature in the general and historical collections of the National Library of Medicine is available on interlibrary loan to any library. If you would like to access NLM medical literature, then visit a library in your area that can request the publications for you.20
Finding a Local Medical Library The quickest method to locate medical libraries is to use the Internet-based directory published by the National Network of Libraries of Medicine (NN/LM). This network includes 4626 members and affiliates that provide many services to librarians, health professionals, and the public. To find a library in your area, simply visit http://nnlm.gov/members/adv.html or call 1-800-338-7657.
Medical Libraries in the U.S. and Canada In addition to the NN/LM, the National Library of Medicine (NLM) lists a number of libraries with reference facilities that are open to the public. The following is the NLM’s list and includes hyperlinks to each library’s Web site. These Web pages can provide information on hours of operation and other restrictions. The list below is a small sample of

Complement activation occurs by two different sequences, the classic and alternative pathways. The proteins of the classic pathway are termed 'components of complement' and are designated by the symbols C1 through C9. C1 is a calcium-dependent complex of three distinct proteins C1q, C1r and C1s. The proteins of the alternative pathway (collectively referred to as the properdin system) and complement regulatory proteins are known by semisystematic or trivial names. Fragments resulting from proteolytic cleavage of complement proteins are designated with lower-case letter suffixes, e.g., C3a. Inactivated fragments may be designated with the suffix 'i', e.g. C3bi. Activated components or complexes with biological activity are designated by a bar over the symbol e.g. C1 or C4b,2a. The classic pathway is activated by the binding of C1 to classic pathway activators, primarily antigen-antibody complexes containing IgM, IgG1, IgG3; C1q binds to a single IgM molecule or two adjacent IgG molecules. The alternative pathway can be activated by IgA immune complexes and also by nonimmunologic materials including bacterial endotoxins, microbial polysaccharides, and cell walls. Activation of the classic pathway triggers an enzymatic cascade involving C1, C4, C2 and C3; activation of the alternative pathway triggers a cascade involving C3 and factors B, D and P. Both result in the cleavage of C5 and the formation of the membrane attack complex. Complement activation also results in the formation of many biologically active complement fragments that act as anaphylatoxins, opsonins, or chemotactic factors.

The predominant naturally occurring prostaglandins all have two double bonds and are synthesized from arachidonic acid (5,8,11,14-eicosatetraenoic acid) by the pathway shown in the illustration. The 1 series and 3 series are produced by the same pathway with fatty acids having one fewer double bond (8,11,14-eicosatrienoic acid or one more double bond (5,8,11,14,17-eicosapentaenoic acid) than arachidonic acid. The subscript a or ß indicates the configuration at C-9 (a denotes a substituent below the plane of the ring, ß, above the plane). The naturally occurring PGF's have the a configuration, e.g., PGF2a. All of the prostaglandins act by binding to specific cell-surface receptors causing an increase in the level of the intracellular second messenger cyclic AMP (and in some cases cyclic GMP also). The effect produced by the cyclic AMP increase depends on the specific cell type. In some cases there is also a positive feedback effect. Increased cyclic AMP increases prostaglandin synthesis leading to further increases in cyclic AMP.

The target may be a dendrite, cell body, or axon of another neuron, or a specialized region of a muscle or secretory cell. Neurons may also communicate through direct electrical connections which are sometimes called electrical synapses; these are not included here but rather in gap junctions. [NIH] Synapsis: The pairing between homologous chromosomes of maternal and paternal origin during the prophase of meiosis, leading to the formation of gametes.

[EU] Synaptic Transmission: The communication from a neuron to a target (neuron, muscle, or secretory cell) across a synapse. In chemical synaptic transmission, the presynaptic neuron releases a neurotransmitter that diffuses across the synaptic cleft and binds to specific synaptic receptors. These activated receptors modulate ion channels and/or secondmessenger systems to influence the postsynaptic cell. Electrical transmission is less common in the nervous system, and, as in other tissues, is mediated by gap junctions. [NIH] Synergistic: Acting together; enhancing the effect of another force or agent. [EU] Systemic: Affecting the entire body. [NIH]
