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 hip fracture 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 hip fracture, 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 hip fracture, 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 hip fracture. 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 hip fracture, 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 hip fracture. The Editors

CHAPTER 1. STUDIES ON HIP FRACTURE Overview In this chapter, we will show you how to locate peer-reviewed references and studies on hip fracture.
The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and hip fracture, 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 “hip fracture” (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: •
Risk of Hip Fracture Among Dialysis and Renal Transplant Recipients Source: JAMA. Journal of the American Medical Association. 288(23): 3014-3018. December 18, 2002. Summary: Renal failure places people at particularly high risk of hip fracture. However, the possible differential impact of dialysis and renal (kidney) transplantation on this risk is not well understood. This article reports on a study undertaken to determine if patients who receive kidney transplants are at greater risk of hip fracture compared with those who continue to undergo dialysis. The data is from a cohort study of 101,039 patients with end stage renal disease (ESRD) placed on the renal transplant waiting list in the United States between January 1990 and December 1999. Among the patients included in this analysis, 971 hip fractures were observed during the followup period of 314,767 person-years. The incidence rate of hip fracture in patients receiving dialysis

was 2.9 per 1000 patients per year compared with 3.3 hip fractures per 1000 patients per year in those who had previously received a renal transplant. Initially, the relative risk of hip fracture associated with transplantation was 1.34 fold greater when compared with dialysis, but then decreased by 1 percent per month until the estimated risk became equal for dialysis and transplant recipients approximately 630 days after transplantation. Among transplant recipients, risk of fracture was relatively higher in persons with a prolonged period of dialysis before transplantation. 1 figure. 3 tables. 26 references. •
Type 1 and Type 2 Diabetes and Incident Hip Fractures in Postmenopausal Women Source: Diabetes Care. 24(7): 1192-1197. July 2001. Contact: Available from American Diabetes Association. 1701 North Beauregard Street, Alexandria, VA 22311. (800) 232-3472. Website: www.diabetes.org. Summary: This article describes a study that examined whether postmenopausal women with diabetes experienced a higher incidence of hip fracture than women without diabetes. The study sample consisted of 32,089 postmenopausal women residing in Iowa who were surveyed by mail in 1986 and followed for 11 years. Diabetes status and other potential risk factors were assessed by questionnaire at baseline. Incidence of hip fracture was ascertained by follow up questionnaires. Over 306,900 person years of follow up, 490 hip fractures were identified, for an incidence rate of 1.6 per 1,000 person years. After adjustment for age, smoking status, estrogen use, body mass index, and waist to hip ratio, women with type 1 diabetes were 12.25 times more likely to report an incident hip fracture than women without diabetes. Women with type 2 diabetes had a 1.70 fold higher risk of incident hip fracture than women without diabetes. Longer duration of type 2 diabetes was associated with higher incidence, as was use of insulin or oral diabetes medications in women with type 2 diabetes. Furthermore, women who were initially free of diabetes but in whom diabetes developed had a relative risk of hip fracture of 1.60 compared with women who never had diabetes. The article concludes that postmenopausal women who have diabetes or in whom diabetes develops are at higher risk for hip fracture than postmenopausal women without diabetes. Strategies to prevent osteoporosis or falling may be especially warranted in women with diabetes. 2 tables. 31 references. (AA-M).

Risk Factors for Hospital-Acquired Incontinence in Elderly Female Hip Fracture Patients Source: Journal of Gerontology. 57A(10): M672-M677. 2002. Summary: This article reports on a study undertaken to estimate the incidence of, and identify risk factors for, urinary incontinence in female hip fracture patients. The study was a secondary analysis of data abstracted from medical records in hospitals in Pennsylvania, Texas, New Jersey, and Virginia. The study included women aged 60 years and older who were admitted to one of the study hospitals with hip fracture. Data from 6,516 women were analyzed. Of these, 21 percent (n = 1,365) became incontinent during hospitalization. After adjusting for confounders (i.e., age, race, malnutrition, comorbidity, and severity of illness), admission from a nursing home or other long-term care facility, confusion, use of a wheelchair or device for walking, and prefracture dependence on others for ambulation significantly increased the odds of developing incontinence during hospitalization. The authors conclude that certain easilyidentifiable patient characteristics place female hip fracture patients at high risk of incontinence. Interventions to increase staff awareness of this vulnerable population

need to be tested to minimize the incidence of hospital-acquired incontinence. 1 figure. 3 tables. 26 references. •
Randomised, Clinically Controlled Trial of Intensive Geriatric Rehabilitation in Patients With Hip Fracture: Subgroup Analysis of Patients With Dementia Source: BMJ. British Medical Journal. 321: 1107-1111. November 4, 2000. Summary: This journal article describes a study that investigated the effectiveness of intensive geriatric rehabilitation in people with mild to moderate dementia who had surgery for hip fracture. Participants were 243 people over age 64 years who lived independently and were admitted to the hospital with a hip fracture. Patients were evaluated to determine cognitive status. Following surgery, patients in the intervention group were referred to the geriatric ward, while the remaining patients were discharged to local hospitals. The study measured their length of hospital stay, place of residence at three months and one year after surgery, and mortality. The median length of hospital stays was significantly shorter in the intervention group. Three months following surgery, patients with mild dementia in the intervention group were as successful as people without dementia in returning to independent living. Severity of cognitive impairment related to less successful return to independent living and higher mortality. The researchers concluded that older people with mild to moderate dementia and hip fracture can return to community living if they receive active geriatric rehabilitation. 3 tables, 34 references.

Rehabilitation Following Hip Fracture in Patients With Alzheimer's Disease and Related Disorders Source: American Journal of Alzheimers Disease. p. 209-211. September-October 1997. Summary: This journal article describes the rehabilitation outcomes of 19 patients with hip fractures admitted to a long-term care facility dedicated to caring for people with Alzheimer's disease and related disorders (ADRD). The patients ranged in age from 80 to 90 years, and most were female; all but one had surgery. The patients received physical therapy for 1 to 24 weeks. The physical therapy program included upper and lower extremity strengthening, balance training, transfer training, and gait training with and without assistive devices. At discharge, all 17 patients who survived were able to ambulate at least 100 feet with or without assistive devices. Some required assistance for safety due to decreased judgment and cognition, four were able to ambulate totally independently ad lib, and five needed supervision only. At followup several months later, most of the patients were still ambulatory at the same level as that at discharge. The authors conclude that people with ADRD who sustain hip fractures can be successfully rehabilitated with sufficient time and effort. 16 references. (AA-M).

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 hip fracture. 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 hip fracture. The following is typical of the type of information found when searching the CRISP database for hip fracture: •
Project Title: A LOW-COST FALL MONITOR FOR GERIATRIC SUBJECTS Principal Investigator & Institution: Parker, B Eugene.; Barron Associates, Inc. 1410 Sachem Place Charlottesville, Va 22901 Timing: Fiscal Year 2003; Project Start 01-OCT-2000; Project End 31-AUG-2005 Summary: (provided by applicant): Falls are a leading cause of disability and even death in the elderly. A method is needed by which to identify elderly persons who frequently experience falls or near falls (e.g., slips, stumbles, etc.). There are presently no tools to objectively record such events and their characteristics (e.g., kinematics) in independentliving, assisted-living, or nursing-home environments. A device that could be used to discreetly count fall frequency and record the characteristics of fall events - while still permitting free and unrestricted body movement - would be invaluable in understanding why elderly people fall. Such a device could also serve as a research tool, enabling a better understanding of risk factors associated with falls and near falls. A method for characterizing fall dynamics (e.g., impact velocity and orientation, fall direction, impact energy) would assist in identifying elderly persons at high risk for hip fracture. Hip fractures, for example, have been associated with high impact energy sideways falls in which the subject lands on their hip. Under the proposed Phase II SBIR effort, Barron Associates, Inc. and its subcontractors, the University of Kansas Center for Research and the University of Virginia Division of General Medicine, Geriatrics & Palliative Care, propose to develop and demonstrate the Wear And Forget Ambulatory Recorder for Elderly Residents (WAFARER), a wireless system to detect, archive, characterize, and "reconstruct," through PC-based graphical reenactment, fall and nearfall events in the elderly with the goals of understanding and preventing fall-related injuries and their sequelae. Three-dimensional animation of pelvic motions during fall and near-fall events will facilitate their interpretation by senior-care facility physicians, nurses, and others.

Project Title: A NEW SYSTEM FOR ULTRASONIC BONE ASSESSMENT Principal Investigator & Institution: Kaufman, Jonathan J.; President & Ceo; Cyberlogic, Inc. 611 Broadway, Ste 707 New York, Ny 10012 Timing: Fiscal Year 2002; Project Start 01-NOV-1997; Project End 31-AUG-2004 Summary: (provided by applicant): The long-term objective of this research is to establish ultrasound as a safe, effective, and non-invasive method for assessing fracture risk, an important component in clinical management of osteoporosis. Osteoporosis afflicts over 20 million people in the U.S., responsible for more than 275,000 hip fractures annually. Currently, the primary means for assessment relies on densitometric
Studies

techniques. These methods subject the patient to ionizing radiation, are relatively expensive, and do not always provide good estimates of bone strength. Ultrasound offers several potential advantages. It is non-ionizing and relatively inexpensive. Moreover, since ultrasound is a mechanical wave and interacts with bone in a fundamentally different manner than electromagnetic radiation, it may be able to provide more accurate estimates of bone strength compared with current densitometric methods. The goal of this research is to significantly improve the effectiveness of current ultrasonic bone assessment techniques by demonstrating the feasibility of a new ultrasonic system to assess bone. The system employs a novel parametric signal processing approach which is ideally suited for analog and real-time implementation. Thus this research may enable less expensive and easier to use ultrasound devices, which are also less sensitive to various experimental artifacts. The specific aims are to measure a set of new ultrasonic parameters and compare them with presently used features, namely BUA and ultrasound velocity, in calcaneal bone samples. A comparison will be made of their respective capabilities to estimate bone density and bone strength. This comparison will include cost, ease of use, and accuracy and precision of the bone density and bone strength estimates. PROPOSED COMMERCIAL APPLICATION: Osteoporosis is a major health concern in the United States, afflicting over 20 million people, and whose incidence is increasing as the average age of the U.S. population increases. An effective, relatively inexpensive and safe technique such as ultrasound for assessing osteoporosis would be an extremely emportant benefit to the patient population, and represents an enormous commercial opportunity. Ultrasound's importance will grow as various new pharmacologic agents are approved for treatment, thus requiring periodic assessments of efficacy.

Project Title: ACTIVITY GAIT AND EFFICACY (AGE) IN ORDER WOMEN Principal Investigator & Institution: Mcauley, Edward; Professor; Kinesiology; University of Illinois Urbana-Champaign Henry Administration Bldg Champaign, Il 61820 Timing: Fiscal Year 2004; Project Start 01-SEP-2001; Project End 31-JUL-2006 Summary: (provided by applicant): Osteoporosis is a major public health issue. Being African-American affords some protection from osteoporotic fracture primarily due to bone dependent factors such as a higher bone mass, density and shorter hip axis length; however, pilot data from our laboratory also suggests a racial difference in bone independent fracture risk factors including gait, balance and social cognitive factors such as fear of falling. However, to our knowledge, no research has studied the interrelationship between bone dependent and independent fracture risk factors in an older racially diverse sample of postmenopausal women. Additionally, little research has prospectively examined the relation between and among bone dependent and independent risk factors in black and white postmenopausal women. This is important work because black women are among the fastest growing segment of the population and alarming evidence suggests that although fewer black women sustain osteoporotic fractures, they have nearly a three-times greater likelihood of death due to complications from hip fracture. Thus, the primary purpose of this prospective study is to combine physiological bone health outcomes (bone mass, density and ultrasound attenuation), physical activity patterns, and balance and gait abilities with social cognitive outcomes including self-efficacy and expectations, to further elucidate the causes of this racial discrepancy in fracture rate. Secondarily, racial differences in body composition determinants (i.e. fat and fat-free mass) of bone health will be explored at

Hip Fracture
baseline and in a prospective fashion. Per the parent grant design (1R01AG02011801A1), a large sample of older (60 - 80 yrs) white (N = 150) and black (N = 150) women will be recruited with outcomes assessed at baseline, 1 year and 2 years. Bone and body composition will be assessed by dual energy X-ray absorptiometry (DXA). Additionally, quantitative ultrasound (QUS) will be used as an index of bone quality. This research has high public health priority because bone dependent and independent factors that influence the risk of osteoporotic fracture risk must be understood to implement effective programs for public health agendas and programs, specifically with regards to racial differences thereby optimizing programming for all individuals.

Project Title: ADVANCE REHABILITATION RESEARCH TRAINING PROJECT Principal Investigator & Institution: Rodgers, Mary M.; Professor and Chair; Physical Therapy; University of Maryland Balt Prof School Baltimore, Md 21201 Timing: Fiscal Year 2003; Project Start 20-JUN-2003; Project End 30-APR-2008 Summary: (provided by applicant): Societal demand for high quality rehabilitationrelated research relevant to chronic diseases and disabilities is increasing with the aging of the population in the United States. The objective of the proposed Advanced Rehabilitation Research Training Program (ARRTP) is to provide trainees with academic and research preparation in fields pertinent to the emerging discipline of physical rehabilitation science (PRS). The existing UMB-PRS program, which will be augmented by this ARRTP, offers predoctoral students and post-doctoral fellows an educational curriculum and laboratory experiences with an emphasis in one of five academic subdisciplines or concentration areas: applied anatomy and cell biology, rehabilitation biomechanics, epidemiology, neuromotor control/plasticity, and rehabilitation physiology. Trainees are subsequently afforded research development opportunities in areas where participating faculty have ongoing externally funded collaborations. These areas include stroke, spinal cord injury, hip fracture, rheumatological/immunological diseases and developmental disorders. The training program features rigorous academic and research requirements that are individually tailored to develop scientists that are capable of becoming independent investigators. It is expected that graduates and fellows will be capable of drawing on the skills and informational bases of their chosen sub-discipline to expand overall knowledge related to the mechanisms and epidemiology of physical disability and rehabilitation. Additional opportunities for collaborative research across campus are available through established training programs in neurology, geriatrics, pediatrics, epidemiology and rheumatology. The strengths of the proposed ARRTP are (1) strong institutional and school support, (2) an interdisciplinary faculty, (3) ongoing interdisciplinary research in suitable fields, and (4) well-equipped laboratories. The didactic portion of the program includes course work designed to develop competence in foundational sciences, analytical methodologies, and a substantive concentration area through formal lectures, independent study, research seminars, journal clubs, and regular training in the ethical conduct of research. The training program is designed to enable trainees to (1) master a core curriculum in foundational biophysical sciences and scientific methodologies, (2) become knowledgeable about fundamental rehabilitative and psychosocial processes related to disability, (3) become expert in at least one substantive area relevant to the reversal of impairment and functional decline in a disabled population, (4) learn to contribute to a research team under the supervision of a primary mentor expert in a disability-specific field with appropriate mentorship by secondary and associate experts in rehabilitation

research, and (5) demonstrate the capacity to conduct independent, original research related to rehabilitation. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: ANALYSIS OF INJURY AVOIDANCE STRATEGIES DURING FALLS Principal Investigator & Institution: Lotz, Jeffrey Charles.; Professor; Orthopaedic Surgery; University of California San Francisco 500 Parnassus Ave San Francisco, Ca 941222747 Timing: Fiscal Year 2002; Project Start 20-SEP-2000; Project End 31-AUG-2004 Summary: At least 280,000 hip fractures occur annually in the U.S., at an estimated cost of $9 billion. While over 90% of these are caused by falls, only about 2% of all falls result in hip fracture. Considerable evidence now exists that the most important determinants of hip fracture risk during a fall are the body's impact velocity and configuration (and in particular, whether contact occurs to the hip region). Accordingly, protective responses for reducing impact velocity, and the likelihood for direct impact to the hip, strongly influence fracture risk. Improved understanding of the nature of such responses, and how these are affected by age-related declines in neuromuscular variables, would enhance our ability to develop exercise- based strategies for hip fracture prevention. Based on the results of epidemiological and biomechanical studies, we hypothesize that two protective responses central to safe landing during a fall are (a) absorbing energy in the lower extremity muscles during the descent phase of the fall, and (b) braking the fall with the outstretched hands. We also hypothesize, based on epidemiological evidence, that the efficacy of these responses associate with strength, flexibility, and reaction time. To test these hypotheses, we will address four aims. Aim 1 is to test whether use of the above protective responses influences young females' ability to avoid impact to the hip, and reduce the impact velocity of the body during falls onto a soft gymnasium mat. Aim 2 is to test whether ancillary measures of balance and lower extremity flexibility and reaction time associate with young and elderly subjects' ability to absorb energy in their lower extremity muscles, and reduce impact velocity when descending from standing to sitting. Aim 3 is to test whether balance and upper extremity strength, flexibility, and reaction time associate with young and elderly subjects' ability to quickly contact an impact surface with the outstretched hands, and absorb energy in the upper extremity muscles during simulated falls. Finally, Aim 4 is to develop and validate complementary mathematical models of falling, and use these to determine how specific impairments (or exercise-induced enhancements) in muscle strength, joint flexibility. Finally, Aim 4 is to develop and validate complementary mathematical models of falling, and use these to determine how specific impairments (or exercise-induced enhancements) in muscle strength, joint flexibility, and reaction time affect fall protective responses and fall severity. By identifying the biomechanical and neuromuscular variables which govern safe landing during a fall, these studies should lead to novel and effective interventions for reducing hip fractures in the elderly.

Project Title: BBA EFFECTS ON GEOGRAPHIC VARIATION IN POST-ACUTE CARE Principal Investigator & Institution: Lin, Wen-Chieh; Family and Community Medicine; University of Missouri Columbia 310 Jesse Hall Columbia, Mo 65211 Timing: Fiscal Year 2003; Project Start 01-SEP-2003; Project End 31-AUG-2004

Hip Fracture
Summary: (Provided by Applicant): In response to the rapid growth in payments for post-acute care (PAC) services, Congress enacted Medicare reforms as part of the Balanced Budget Act of 1997 (BBA) for each PAC service. The reforms mandated a series of separate case-mix adjusted prospective payment systems, each with its own implementation timeline. In addition to the overall effects, the BBA's effects on PAC use varied substantially across geographic areas. For example, in the case of skilled nursing facility use from 1998 to 2000, the average change relative to 1996 for stroke patients was 2.7%.at the national level, but it ranged from -12% to 24% across regions (the nine United States Census Bureau divisions). This varied response raises concerns that the hospital discharge process may be driven by payment policy rather than by clinical needs and individual preferences. Furthermore, varied changes in PAC use across regions might lead to untoward consequences, such as early hospital readmission. As efforts continue to reform PAC services and payment systems, it is essential that policymakers understand how different payment mechanisms associate with geographic variation in PAC use. The proposed study seeks to: 1) analyze geographic variation in PAC use before and after the BBA changes; 2) explore whether utilization and cost have shifted among PAC settings and whether early hospital readmission has increased; and 3) investigate how the contributions of patient, hospital, and market area characteristics in explaining PAC use differ between pre- and post-BBA periods. We will analyze the Center for Medicare & Medicaid Services' 5% sample of Medicare claims data from 1996 to 2000 to study the initial effect of the BBA changes on geographic variation in PAC use. We will focus on six diseases associated with high PAC use: stroke, hip procedure, hip fracture, chronic obstructive pulmonary disease, pneumonia, and congestive heart failure. The selected diseases provide a contrast between rehabilitative and medical conditions. The stability, the degree, and the association of geographic variation in PAC use before and after the BBA changes will be examined. Shifts in utilization and costs will be presented as correlations between changes in PAC use, hospital length of stay, and early hospital readmission. Finally, we will estimate multinomial logit models to explore changes in contribution to explain PAC use by patient, hospital, and market area characteristics after the BBA changes.

Project Title: CHARACTERISTICS OF T CELL RECEPTORS Principal Investigator & Institution: Marrack, Philippa C.; Investigator; National Jewish Medical & Res Ctr and Research Center Denver, Co 80206 Timing: Fiscal Year 2003; Project Start 01-MAY-1982; Project End 30-APR-2006 Summary: T cells bearing alphabeta T cell receptors react with antigen in the form of peptides bound to major histocompatibility complex proteins (MHC). This reaction is crucial to the ability of T cells to orchestrate destruction of invading organisms. It is also involved in graft rejection and in T cell attacks on the tissues of their own host in autoimmune disease. Several aspects of T cell reaction with MHC are not understood. The projects in this application will study two of these aspects. The first set of experiments will study the ways in which T cells are selected to react with peptides bond to MHC in the thymus. A major focus of these experiments will be the role of the peptides bound to MHC. Mice will be created in which a single peptide is firmly bound to an MHC protein, and the ability of this MHC/single peptide combination to select T cells studied. The second set of experiments will investigate the relationship between T cell receptors and MHC. It is thought that the two sets of proteins may have an intrinsic affinity for each other. Experiments proposed here will try to find out if this is so. T cells

from the MHV/single peptide mice, which are very reactive with MHC proteins, will be used to study the phenomenon. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: CLAUDE D. PEPPER OLDER AMERICANS INDEPENDENCE CENTER (O* Principal Investigator & Institution: Goldberg, Andrew P.; Professor; Medicine; University of Maryland Balt Prof School Baltimore, Md 21201 Timing: Fiscal Year 2002; Project Start 15-JUL-1994; Project End 30-JUN-2006 Summary: (provided by the applicant): The mission of the University of Maryland, Baltimore (UM)-OAIC is to conduct mechanistic and outcome-based research in exercise rehabilitation and provide research training in gerontology and geriatrics that will improve lifestyle and functionality for millions of older disabled Americans. The research focus is on older patients who are chronically disabled by hemiparetic stroke, a major complication of arteriosclerotic cardiovascular disease (CVD) which affects greater than 750,000 Americans annually. These patients have reduced ambulatory capacity and functionality, impaired IADL performance, gait dysfunction and a multitude of comorbidities, which worsen their quality of life and increase their utilization of the healthcare system. While our focus is on hemiparetic stroke, the UMOAIC also collaborates with and provides infrastructure support for research on peripheral arterial occlusive disease, hip fracture and other disabling conditions where there are institutional strengths. Exercise rehabilitation is the consistent theme in the UM-OAIC that provides cohesiveness for the research training, the research resources cores, education, dissemination, and clinical care. The intervention development studies (IDS) examine the effects of task-oriented treadmill exercise in patients with lower extremity hemiparesis (IDS-1) and upper extremity training with auditory cueing in patients with upper extremity paresis (IDS-2) on: 1) functional mobility and ambulation, motor control and strength, V02 peak, and free living daily activity; 2) central (neural) and peripheral (muscle) mechanisms underlying these functional responses using functional magnetic resonance imaging (fMRI) and transcranial magnetic stimulation (TMS) to assess neural plasticity; 3) muscle biopsies with histochemical and biochemical analyses to determine conditioning; and 4) long-term functionality and psychosocial status in hemiparetic stroke patients. These and other studies of disabling conditions utilize RRCs in 1) epidemiology research and recruitment; 2) neuromuscular mechanisms and function performance; and 3) physiology that are blinded to patient randomization for measuring outcomes. The biostatistics RRC provides data management and analysis, and maintains confidentiality and records for the safety monitoring board. OAIC leadership and advisory committees 1) guide and review accomplishments of the RCT?s on hemiparetic stroke, 2) train young investigators in mechanistic, functional, and psychosocial research examining physiologic as well as cellular adaptations to exercise and outcomes research, 3) promote collaboration of UMB and Johns Hopkins faculty in interdisciplinary aging research and research training, and 4) disseminate OAIC findings to the public and health professionals. OAIC leaders have institutional support for interdisciplinary aging research that supports a cadre of gerontologists to achieve the interdisciplinary research goals of the OAIC.

Hip Fracture
Timing: Fiscal Year 2002 Summary: (provided by the applicant) The clinical/applied physiology core (RRC-C) will be directed by Leslie l. Katzel, MD, Ph.D. with Andrew R. Coggan, Ph.D., Andrew W. Gardner, Ph.D. and Alice Ryan Ph.D. as core investigators. The specific aims of RRCC are: 1) to perform cardiovascular screening (treadmill exercise testing) of research patients entering IDS 1 and 2, and in the pilot and junior faculty projects that require these measurements; 2) to provide standardized and quality controlled measures of: A) peak aerobic capacity (V02 peak); B) walking economy; C) functional performance; D) physical activity; and E) body composition in patients enrolled in IDS1 and 2, and in other OAIC projects; 3) To determine the effects of exercise training on skeletal muscle histochemistry in stroke patients (IDS1), and in other OAIC patients undergoing exercise rehabilitation; 4) To provide standardized and quality controlled measures of fibrinolysis and other CAD risk factors;5) To train young investigators in geriatrics and gerontology in the performance of applied exercise physiology and metabolism research relevant to the mission of the Pepper Center (collaborative project with RDC); 6) To provide an educational and consultative resource for all investigators interested in aging and exercise at UMB; and 7)To assist other funded NIH and VA investigators in the evaluation of the cardiovascular and metabolic effects of exercise rehabilitation in older patients with CAD risk factors, hip fracture and peripheral arterial disease. The RRC-C will provide a framework to evaluate patients during their exercise rehabilitation interventions of the OAIC. The performance of standardized measures of cardiovascular function, muscle characteristics, body composition, physical activity, and cardiac risk factors in the RRC-C, rather than in the individuals studies improves the accuracy and efficiency of the measurements through the use of personnel trained in the performance of these procedures, and allows the strict maintenance of blinding as critical outcomes measurers are tested. It also eliminates duplicate equipment. Centralization of these measurements should increase the intraclass correlation coefficients of the measurements, decrease the coefficient of variation, enhance data entry, data management and oversight to assure the integrity of the data, and its subsequent analysis by the biostatistics core (RRC-D). The collection of physiologic data and its integration with data collected in the projects and other cores enable comprehensive, multidisciplinary examinations of physiologic factors associated with exercise-induced changes in functional performance, gait biomechanics and quality of life in stroke. The RRC-C will also collaborate with RDC to develop the research skills of junior faculty interested in clinical research and gerontology.

related research at UMB by providing quantitative and standardized measures of gait, balance, strength and motor control; 2. Investigate the effects of repetitive bilateral UE and LE task-oriented training on CNS motor control in hemiparetic stroke patients using novel non-invasive transcranial magnetic stimulation (TMS) and functional magnetic resonance imaging (fMRI). In collaboration with RRC-C studies of muscle mass and metabolism, this will identify the central and peripheral neuromuscular adaptations with treadmill training in IDS-1; 3. Train young investigators, RDC-OAIC awardees, and clinicians in the conduct of human performance and applied neurophysiological research relevant to the mission of the Pepper Center, and the fields of gerontology, neurology, and physical rehabilitation sciences; 4. Provide an educational and consultative resource for UMB investigators interested in pursuing research in aging and neurological rehabilitation; 5. Assist NIH and/or VA-funded investigators at UMB in the performance of rehabilitation research, particularly exercise rehabilitation studies in hip fracture and cortical excitability (RDC pilots, NSA and VA-CDA, NIH R37 MERIT), revascularized PAOD (R01), personal status monitoring of physical activity (VA MERIT) and other relevant rehabilitation research; and 6. Further inter-institutional collaborations in stroke and other rehabilitation research among investigators at UMB, Johns Hopkins University (JHU), the Human Cortical Physiology Section at the National Institutes of Health, Sinai Hospitals and other Pepper Centers. Conduct of laboratorybased and standardized measures of functional performance, cortical and peripheral neuromuscular adaptations in the RRC-B improves the accuracy of these assessments, allows strict maintenance of blinding as critical mechanistic outcomes are determined. and eliminates duplication of expensive testing equipment. Centralization of major mechanistic questions relevant to the IDS-1, IDS-2 and the RDC pilot studies into one core ensures the integrity of the methodologies and analysis. Collection of functional and neurophysiologic data by RRC-B investigators, and subsequent integration with data collected in IDS projects and research resources cores enables a comprehensive, multi-disciplinary examination of mechanistic factors associated with exercise rehabilitation in stroke. The RRC-B provides goal directed organization to precisely identify neuromuscular and cortical mechanisms of functional performance leading to adaptive modes of recovery after stroke and other disabling medical conditions in older populations.

Project Title: CORE--MEDICAL Principal Investigator & Institution: Williams-Russo, Pamela; Weill Medical College of Cornell Univ New York, Ny 10021 Timing: Fiscal Year 2002 Summary: Geriatric depression is rarely found without at least some medical comorbidity and/or impatient in physical functioning. Not only do these conditions complicate the study of geriatric depression, but evidence from the Developing CRC suggests that they are important indicators of heterogeneity in late life mood disorders and contribute to their outcomes; for example in depressed CRC subjects, medical burden predicts chronicity of depression and delayed recovery is associated with increased mortality. The Medical Core is newly added to the CRC and developed from collaborative relationships between investigators in the Departments of Psychiatry and Internal Medicine at Cornell. Addition of the Medical Core uniquely contributes to the CRC's investigation of heterogeneity of late life mood disorders by rigorous and extensive study of medical illness, functional impairment and depression course and outcome. The Medical Core expands the CRC's resource by providing: 1. funded

medical investigators with extensive experience conducting longitudinal studies of comorbidity in medical setting patients and having central roles in the CRC; 2. access to a large population of elderly medical patients accustomed to receiving care in a research environment; 3. training and supervision in the administration of carefully selected instruments to assess longitudinal variation in medical morbidity and functional performance; (4) investigations of depression in post-operative depression in subjects enrolled in funded longitudinal studies of coronary bypass surgery and hip fracture repair. The Medical Core will work with the Clinical Core in screening and recruiting elderly patients from primary care settings for assessments and longitudinal follow-up, including subjects with major depression (N=50), minor depression (N=50) and nondepressed. These patients will contribute to the overall CRC database, yielding a sample of depressed elderly subjects ranging widely in severity and type of medical comorbidity and functional status, and followed longitudinally with extensive clinical, neuropsychological and psychosocial ratings. As part of its mission, the Medical Core will take advantage of these data to test cross-core hypotheses concerning the reciprocal relationships of depression and medical illness over time.

Project Title: CORE--RECRUITMENT AND EPIDEMIOLOGY Principal Investigator & Institution: Kittner, Steven J.; Professor; University of Maryland Balt Prof School Baltimore, Md 21201 Timing: Fiscal Year 2002 Summary: (provided by the applicant) The potential impact of the IDS-1 and IDS-2 stroke interventions and disability among Americans is enormous, and large-scale trials will be needed to test methods designed to maximize independence. The implementation of these trials will require information regarding the generalizability of findings and the potential personal and societal effects of those interventions. RRC-A is designed both to meet the needs of current UM-OAIC projects and to lay the groundwork for future trials. The specific aims of RRC-A are: 1. Support centralized recruitment and evaluation of factors affecting recruitment. 2. Implement interviewbased measures of outcomes, including basic and instrumental activities of daily living, quality of life, and caregiver burden, as well as potential modifiers of that outcome, including comorbidities, mood, cognitive function, social support, and exercise perception. 3.Develop an innovative approach to modeling the potential health care cost savings of interventions that lead to changes in functional status. There is a compelling rationale for including these services in a core rather than in individual projects. Centralized recruitment of stroke patients for both IDS studies is more efficient, allows study of the determinants of recruitment, and can provide strategic consultation regarding recruitment to other studies of chronic disease in older Americans. Centralized performance of interview-based measures will facilitate training, quality control, standardization, and precision of measurements. The inclusion of a healthservices component in this core makes this expertise available not only to the IDS studies, but also to R01 -funded studies of exercise interventions in peripheral vascular disease and hip fracture patients. The RRC-A will also contribute actively to training young geriatrics and gerontology investigators in epidemiology and health-services research, and will provide resources for the conduct of junior-faculty and pilot studies.

DELIVERY
OF
Principal Investigator & Institution: Kopecek, Jindrich N.; Distinguished Professor and Chairman; Pharmaceutics and Pharmaceutl Chem; University of Utah Salt Lake City, Ut 84102 Timing: Fiscal Year 2002; Project Start 01-APR-1995; Project End 31-DEC-2003 Summary: Osteoporosis is a major cause of morbidity and mortality in postmenopausal women. In an United States, an estimated 13% to 18% of women have osteoporosis. The financial burden is substantial, with an estimated yearly cost of $10 billion in the United States alone. The lifetime risk for osteoporotic fractures in Caucasian women 50 years of age is about 30-40%. Between 13-19% of postmenopausal women who have a hip fracture die within the following year. We propose to use a combination of human calcitonin (hCT) and polymer-bound cathepsin K inhibitor (CKI) as a novel treatment of osteoporosis. The rationales for hCT use in osteoporosis therapy are the stimulation of osteoblasts, specific inhibition of bone resorption by osteoclasts, and prevention of fusion of osteoclast precursors. Clinical studies have shown that a significant gain in bone mass can be achieved by administration of CT. An osteoclast-specific cysteine proteinase, cathepsin K, plays a specialized role in the resorption of organic bone matrix. It was shown that cathepsin K inhibitors (CKI) are effective in reducing osteoclastmediated bone resorption both in vitro and in vivo. The binding of CKI to a macromolecular carrier will change the mechanism of CKI internalization by osteoclasts from diffusion (CKI) to endocytosis (polymer-bound CKI). Consequently, the polymerbound CKI will localize in the sealed zones of the ruffled border (resorption lacuna), i.e. exactly in the place where bone resorption mediated by cathepsin K occurs. We hypothesize that the combination of the actions of hCT and CKI will produce cures which cannot be achieved with hCT or CKI alone. Establishing an oral delivery system for hCT and CKI is of great importance because it is expected that for treatment of chronic disorders in non-life threatening situations, such as postmenopausal osteoporosis, parenteral administration will lead to poor patient compliance and thus restricted utility. hCT is an excellent candidate for the development of alternate delivery routes due to its size and wide therapeutic index. The size of CKIs will be modified with semitelechelic poly[(N-2- hydroxypropyl)methacrylamide] (ST-PHPMA) chains to achieve comparable hydrodynamic volumes of CT and of the ST-PHPMA-CK conjugate, which will simplify the design of the delivery system and have beneficial biological consequences. Novel hydrogels were designed in the first period of research; they contain azoaromatic crosslinks, susceptible to degradation by bacterial enzymes in the colon and hydrolyzable side-chains, which control the kinetics of swelling in the small intestine. The structure and properties of biodegradable hydrogels will be optimized. A new macromolecular CKI will be synthesized. Its efficacy will be evaluated in an osteoclast culture in vitro as well as on an animal model in vivo. The effect of combination therapy will be compared with individual therapies. The bioavailability of hCT and ST-PHPMA-CKI conjugates in rabbits and dogs using hydrogel based delivery devices and a penetration enhancer will be determined. The efficacy and biocompatibility of an hCT and CKI delivery device in an animal model of osteoporosis will be studied. Based on in vivo animal data criteria will be studied. Based on in vivo animal data criteria will be established for the design of an oral hCT and CKI delivery system for the treatment of postmenopausal osteoporosis.

Project Title: DEPRESSION TREATMENT IN MEDICALLY REHABILITATING ELDERLY Principal Investigator & Institution: Lenze, Eric J.; Psychiatry; University of Pittsburgh at Pittsburgh 350 Thackeray Hall Pittsburgh, Pa 15260 Timing: Fiscal Year 2002; Project Start 01-SEP-2001; Project End 31-AUG-2006 Summary: (provided by applicant): This application requests a Mentored PatientOriented Research Career Development Award (K23). The candidate is a geriatric psychiatrist and postdoctoral research fellow at the University of Pittsburgh who proposes to develop research skills for geriatric psychiatry research in medical rehabilitation settings. Funding of this award would provide time and resources necessary for him to develop into an independent investigator capable of conducting depression intervention studies in elderly patients undergoing rehabilitation after disabling medical events such as hip fracture. Studies of elders undergoing rehabilitation suggest that depression is associated with poorer outcomes and an increased likelihood of permanent disability and institutionalization. Therefore, it would be of tremendous public health benefit to determine the most efficacious interventions for late-life depression in the medical rehabilitation setting. However, little such intervention research has been done, in part because not enough is known about depression in this setting, and in part due the difficulty of carrying out psychiatric Intervention studies in this setting. To perform such research, the candidate will develop skills in the areas of psychiatric assessment of patients in medical settings, design of intervention trials, measurement of rehabilitation outcomes, and data management and biostatistical analysis. Proposed research consists of a longitudinal descriptive study characterizing late-life depression in medical rehabilitation settings, leading to a pilot intervention study assessing effects of depression treatment on rehabilitation outcomes. The proposed activities will take place in the NIMH-funded Intervention Research Center for Late Life Mood Disorders, directed by the candidate's sponsor, in the Department of Psychiatry at the University of Pittsburgh.

Project Title: DETERMINANTS OF RECOVERY FOLLOWING HIP FRACTURE Principal Investigator & Institution: Magaziner, Jay S.; Professor; Epidemiology and Prev Medicine; University of Maryland Balt Prof School Baltimore, Md 21201 Timing: Fiscal Year 2002; Project Start 01-SEP-2001; Project End 31-AUG-2005 Summary: Hip fracture is a major public health problem. Results from our previous work demonstrate a 4.6 percent loss of femoral neck bone mineral density (BMD) during the year following a hip fracture; this dramatic loss in BMD is accompanied by notable changes in markers of bone metabolism. The parent project to the proposed ancillary study is a randomized controlled trial of a home-based exercise program intended to minimize losses in BMD, muscle and function following a hip fracture. The proposed ancillary study will evaluate markers of bone metabolism and selected regulating hormones in hip fracture patients who are participating in this intervention study in order to gain a better understanding of the mechanism by which exercise affects bone health during the year following a hip fracture. These markers and hormones also will be evaluated over a one year period in a matched group of non-fracture controls to establish expected levels and changes in markers of bone metabolism among a frail group of older persons who also have low BMD. The primary aims of the proposed study are: 1) to evaluate the role of exercise on bone metabolism following hip fracture by comparing bone metabolism during the year after hip fracture in patients

17
randomized to a home-based exercise intervention with patients assigned to usual care, and 2) to separate the effects of hip fracture on bone metabolism from those of aging in similar persons with low BMD by comparing bone metabolism in hip fracture patients receiving usual care with bone metabolism in a matched group of non-fracture controls. These issues will be addressed using data from 170 female hip fracture patients age 65 plus (100 enrolled in the parent study, and an additional 70 hip fracture patients to be recruited for this ancillary study), and 85 age- and mobility-matched non- fracture controls with BMD Less than 0.82g/cm2. Patients are randomized to a year-long, homebased exercise program to begin when post-acute therapy ends, or usual care. As part of the parent study, 100 patients are having BMD measured during their hospital stay, and again at 2, 6, and 12 months, and blood samples for these 100 patients are being taken, processed, and stored. For the ancillary study, this protocol will be extended to include 70 additional hip fracture patients and 85 non- fracture controls, the latter of which will be measured at point of enrollment and 12 months later. For this ancillary study, all blood samples (i.e., those collected on 100 patients in the parent study and those collected on 70 patients and 85 non- fracture controls in the ancillary study) will be assayed to determine levels of four markers of bone metabolism and three regulating hormones. Information of this type will be useful developing interventions to improve bone health and maximize recovery. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: EARLY DETECTION OF FALLS WITH MULTIDIMENSIONAL SENSORS Principal Investigator & Institution: Xue, Shuwan; Integrated Biomedical Systems 17 Lida Dr Essex Junction, Vt 05452 Timing: Fiscal Year 2003; Project Start 01-JUL-2003; Project End 29-FEB-2004 Summary: (provided by applicant): The long-term objective of the project is to develop and commercialize an intelligent fall detector which can detect a fall in its early phase, well before the individual's hip, arm or head hit the ground Unlike any existing fall detectors which detect the fall after the impact, the new detector will be able to trigger a protective mechanism, e g and inflatable hip pads (and/or wrist pads, head pad) to protect the person from injuries due to the fall. The first application of the intelligent fall detection technology will be the Smart HipSaver This device includes the fall detector and the airbag-like inflatable hip pads which are concealed in comfortable and aesthetically appealing underpants The system will provide the elderly and others who are at the risk of falls with the protection against hip fracture, while affording them the freedom to extend their daily activities outside the specially designed hospital or nursing home rooms, such as the smart room, or rooms with dually stiff floor. The system will be expected to receive much higher user acceptance than the existing hip protectors because the inflatable underpants can be made to look and feel much like regular underpants when not inflated. The key to this system is the intelligent fall detector The goals for the fall detector are 1) The detector must be highly reliable in detecting actual falls, 2) the detector must detect a fall in its early phase, and leave sufficient time for any protective mechanisms to be put in place, 3) the detector should not give false alarms during the user's normal activities. In this proposed study (SBIR Phase I) the feasibility of the fall detector will be investigated with an integrated multidimensional sensor, which includes three linear accelerometers, and three angular rate sensors The fundamental requirements of the sensor, data acquisition and computational hardware and software, and most importantly the multi-dimensional event space discrimination algorithms of fall detection will be determined

Project Title: EFFECT OF LEG STRENGTHENING EXERCISE AFTER HIP FRACTURE Principal Investigator & Institution: Mangione, Kathleen K.; Physical Therapy; Arcadia University 450 S Easton Rd Glenside, Pa 19038 Timing: Fiscal Year 2003; Project Start 01-JAN-2003; Project End 31-DEC-2004 Summary: (provided by applicant): Hip fracture is a common medical problem that can drastically change the quality of life for the elderly person. More than 300,000 older people are expected to fracture a hip each year at an estimated cost of 5 billion dollars. Interventions have not been identified that successfully return a majority of persons to their prefracture level of function following hip fracture. Muscle weakness, loss of balance and decreased physical endurance remain. These impairments are associated with slowed gait speed, decreased independence in ambulation, and inability to perform simple activities of daily living. Therefore, despite the improvements in medical care, functional recovery has not occurred. The purpose of this study is to examine the effectiveness of high intensity strengthening exercise used in the home setting for patients who sustain hip fracture. Intervention will begin six months after fracture to ensure healing of bone and soft tissue. Strengthening exercises will be performed twice a week for ten weeks and will be directed to the lower extremity muscles because of their role in gait and transfers. A control group will receive placebo intervention to the same muscle groups. Outcomes will be compared between groups after the intervention and one year after fracture. Effectiveness will be assessed using an impairment measure (quadriceps muscle force production), a functional limitation measure (gait speed), and a disability measure (self-reported physical function).

Project Title: EFFECT OF THEAPEUTIC TOUCH ON BONE FORMATION IN POSTMENOPAUSAL WOMEN AFTER WRIST Principal Investigator & Institution: Prestwood, Karen M.; Assistant Professor and Associate Direct; University of Connecticut Sch of Med/Dnt Bb20, Mc 2806 Farmington, Ct 060302806 Timing: Fiscal Year 2002; Project Start 01-JUL-2001; Project End 30-JUN-2002 Summary: (provided by applicant): Therapeutic touch is a contemporary interpretation of several ancient healing arts developed in the 1970?s by Dolores Krieger, PhD, RN and Dora Kunz, a well known healer. Therapeutic touch is the probably the best researched form of biofield or energy medicine and has been shown to be effective in a wide variety of diseases. Osteoporosis is a common disease in older adults that may result in increased disability or mortality, especially in women or men with spine or hip fractures. Over 50% of women who fracture a hip do not return to pre-fracture function and those with vertebral fractures frequently suffer from chronic pain and associated disability. Anecdotal experiences and unpublished data suggest that therapeutic touch may speed fracture healing and functional recovery after fracture, although this has not been well studied. If therapeutic touch is beneficial to fracture recovery then its use might become an important part of fracture treatment. Serum and urine biochemical markers have been used in the diagnosis and to monitor treatment in metabolic bone disease for many years. Individual markers reflect bone resorption and bone formation and these measures have been shown to be associated with more invasive and cumbersome measures of bone remodeling. Although studies evaluating the use of
Studies
19
markers after fracture are not well controlled, they suggest that bone formation decreases immediately after fracture then gradually increases and finally returns to the normal range at 6 months to 1 year after fracture. Persons with slower healing fractures have a more gradual rise and more prolonged increase in bone formation markers over time. To begin to examine the overall hypothesis that therapeutic touch may affect fracture healing, we propose to first look at the effect of therapeutic touch on markers of bone formation (and resorption) over time in women who have suffered a recent wrist fracture. We hypothesize that therapeutic touch will prevent the immediate decrease and will result in a more rapid rise and a faster return to normal values of markers of bone formation after fracture, compared to sham therapeutic touch. We will examine the effect of 3 different therapeutic touch treatment courses (or doses) on bone formation and hypothesize that any of the doses of therapeutic touch that we are testing will alter bone formation after fracture, compared to sham therapeutic touch, but that women who receive the highest dose will have the greatest response. We also hypothesize that stimulation of bone formation by therapeutic touch will be associated with altered levels of insulin-like growth factor I and binding protein 3.

Project Title: EFFECTS OF SOMATOKINE IN MYOTONIC DYSTROPHY TYPE 1 Principal Investigator & Institution: Moxley, Richard T.; Professor; University of Rochester Orpa - Rc Box 270140 Rochester, Ny 14627 Timing: Fiscal Year 2003; Project Start 30-SEP-2003; Project End 31-MAY-2008 Summary: These phase 1 studies examine a possible new treatment for myotonic dystrophy type1 (DM1), the most common form of adult muscular dystrophy. At present no treatment exists to reverse its progressive wasting and weakness. Low levels of testosterone and growth hormone, as well as insulin resistance, appear to contribute to the muscle loss, but therapeutic trials to reverse these hormonal abnormalities have failed to produce significant improvement. A previous trial of insulin-like growth factor1 [IGF1] has offered promise. Treatment with rhlGF1 increased strength, protein synthesis, and insulin action in 7 patients but side effects caused 2 to drop out. A new, better tolerated, longer acting, preparation of rhlGF1, is now available from INSMED. It is SomatoKine, rhlGF1 in complex with recombinant human IGF binding protein 3, and it will be used in this proposal. Preliminary studies show it is safe and well tolerated in healthy adults, diabetics, and older women treated after hip fracture. We will evaluate SomatoKine in DM1. The aim of this proposal is to evaluate the safety and feasibility of daily subcutaneous injections of SomatoKine for treatment of muscle wasting and weakness by performing two sequential studies, each involving 15 patients with DM1: 1st) An initial 24-Week Dose Escalation Study of SomatoKine [0.5, 1.0, and 2.0 mg/kg, with each dose given daily for 8 weeks] to identify an "optimal dose" based upon the side effects, drug levels, and efficacy [dual energy x-ray absorptiometry (DEXA); quantitative myometry; manual muscle strength testing] observed at each dose; 2nd) A subsequent 24-Week study of SomatoKine using an "Optimal Dose" to demonstrate its safety and feasibility as a daily treatment for a six month period. In addition, we will search for evidence of altered signaling along the intracellular pathway for IGF1 by measuring phosphorylation of p70S6K in needle muscle biopsy specimens obtained from 10 DM1 patients in the 24-Week "Optimal Dose" SomatoKine Study and from 10 age-gender matched normal volunteers who will receive SomatoKine for only two days. Specimens will be obtained from vastus lateralis muscle before and after two days of "optimal dose" treatment. These studies will test our hypothesis that supraphysiologic levels of IGF1 are safe and well tolerated and provide preliminary data regarding

efficacy (reversal of muscle wasting and weakness.) If the results of this project prove promising, we plan to carry out a larger, multi-center, phase 2, controlled trial of SomatoKine. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: ENDOSTEAL BONE VOLUME REGULATION AND OSTEOPOROSIS Principal Investigator & Institution: Mohan, Subburaman; Research Professor; Loma Linda Veterans Assn/Research Educ C/O Research Service (151) Loma Linda, Ca 92357 Timing: Fiscal Year 2002; Project Start 01-AUG-1981; Project End 30-JUN-2007 Summary: (provided by applicant): The long-term goal of this project is to identify the molecular mechanisms responsible fur the pathogenesis of senile osteoporosis. Because impaired bone formation (BF) is a major contributor to this disease, and because of the importance of the IGF system in the regulation of BF, our studies have focused towards identifying the role of individual IGF system components in the regulation of BE. In this regard, studies during the past grant period have revealed that: (1) IGF binding protein5 (BP-5) could increase BE via a mechanism independent of IGFs (i.e. BP-5 is a growth factor); and (2) BP-5 could function as a physiologic regulator of BF, and that low serum BP-5 could play a pathogenic role in hip fracture patients. In order to define the role of BP-5 as a BE regulator, we need to understand the molecular mechanisms controlling the level of BP-5 and the molecular pathways involved in BP-5 action in bone. To this end, we have made two exciting and pivotal discoveries which form the basis for the continuation studies proposed in this application: (1) ADAM-9 (A Disintegrin And Metalloprotease) is an BP-5 protease in osteoblasts (OBs); and (2) FHL2 (Four and a Half LIM Domain) interacts with BP-5 in OBs. ADAM-9 and FHL2 are newly discovered proteins and relatively little is known about any aspects of these proteins in bone. Studies proposed in Specific Aim 1 deal with the role of ADAM-9 in OBs and these studies are based on the hypothesis that degradation of BP-5 by ADAM-9 is a key control mechanism in regulating BP-5 concentrations in the conditioned medium (and perhaps serum) and, thereby, osteoblast proliferation/differentiation. To this end, we will express recombinant ADAM-9 and test whether purified recombinant ADAM-9 cleaves BP-5 but not other IGFBPs. To evaluate if ADAM-9 is the predominant BP-5 protease, we will perform immunodepletion experiments with antibodies specific to ADAM-9 in the conditioned medium of human OBs. To determine if ADAM-9 is regulated, we will test the effect of osteoregulatory agents, known to modulate BP-5 proteolysis, on synthesis and activity of ADAM-9. To evaluate the functional role of ADAM-9, we will modulate expression of ADAM-9 in human OBs by transgenic approaches using MLV vectors and determine the consequence of changes in ADAM-9 expression on BP-5 proteolysis and BF parameters in vitro. Studies proposed in Specific Aim 2 deal with the role of FHL2 in OBs, and these studies are based on the hypothesis that FHL2 interacts with BP-5 and mediates IGF-independent actions of BP-5 in OBs. To test if BP-5 binds to FHL2 and shuttles it to the nucleus, we will over-express wildtype/nuclear localization sequence mutated BP-5 along with FHL2 fused to different fluorescent proteins and use a fluorescent energy transfer technique to monitor interactions between FHL2 and BP-5. To evaluate the significance of BP-5 interaction with FHL2, we will test the effects of BP-5 on bone formation parameters in mice lacking functional FHL2. We will also evaluate the BP-5 functional pathway by applying the ProteinChip Arrayer to determine if the complex of BP-5/FHL2 binds to other proteins in the nucleus of OBs. Successful completion of the proposed studies will provide information on the molecular pathways involved in the regulation of the BF process, which will eventually lead to better understanding the pathogenesis of why some

Project Title: ESTROGEN REGULATION OF OSTEOCLASTOGENESIS IN OLDER MEN Principal Investigator & Institution: Taxel, Pamela; Medicine; University of Connecticut Sch of Med/Dnt Bb20, Mc 2806 Farmington, Ct 060302806 Timing: Fiscal Year 2003; Project Start 01-JUL-2003; Project End 30-JUN-2005 Summary: This R03 proposal is in response to Research Objective #17, entitled Basic Underlying Mechanisms of Musculoskeletal Aging. Male osteoporosis and hip fractures, primarily diseases of older men, have been poorly studied until recently. While there are numerous factors that cause osteoporosis and determine fracture risk, decreases in gonadal steroids with aging are known to influence bone metabolism in both men and women. Recent evidence has demonstrated the importance of estrogen (E2) in male bone health. E2 exerts a variety of important physiological effects, which are mediated via two estrogen receptors found in adult bone, although the mechanisms by which they interact is not well understood. In preliminary work we have found that ovariectomy in mice is rapidly followed by an increase in the ability of bone marrow cells to differentiate into osteoclasts, the cells that mediate bone resorption. This finding suggests that E2 regulates the ability of hematopoietic precursor cells to differentiate into osteoclasts, a process that has not been adequately examined. The studies of this proposal represents a collaboration between basic and clinical researchers who wish to determine if human bone marrow cells from older men respond to E2 in a manner similar to that which we have demonstrated in our murine model. Since increased rates of bone resorption appear to be the earliest known effects of estrogen withdrawal on the human skeleton, a better understanding of this process may lead to more effective therapies for the treatment of osteoporosis in both men and women. A unique model in which to better understand the role of E2 in men is that of men undergoing hormonal suppression with LHRH agonists for locally advanced prostate cancer. This therapy leads to hypogonadism, with both low testosterone (T) and E2 levels within a few weeks. Since E2 therapy has been previously used to achieve medical castration, adding back E2 in these men is acceptable and allows the study of the mechanisms of E2 action on bone without the simultaneous influence of T. As the mechanisms of E2 action on male bone metabolism are better understood, it should be possible to analyze these interactions more precisely and develop more specific interventions based on a better understanding of these interactions.

Project Title: EVALUATION OF OSTEOPOROSIS PREVENTION IN THE ELDERLY Principal Investigator & Institution: Tosteson, Anna N A.; Associate Professor; Community and Family Medicine; Dartmouth College 11 Rope Ferry Rd. #6210 Hanover, Nh 03755 Timing: Fiscal Year 2002; Project Start 05-JAN-1995; Project End 31-AUG-2007 Summary: (provided by applicant): The broad objective of this research proposal is to improve the health of elderly men and women by identifying more effective osteoporosis prevention and treatment strategies. Osteoporosis disproportionately affects the elderly and is associated with fractures that result in disability, death, and a large expenditure of health care resources. A growing number of interventions are
22
Hip Fracture
available to prevent, diagnose, and treat osteoporosis. Cost-effective use of most such interventions requires selective targeting of high-risk populations, yet our previous research documents significant variation in clinical outcomes, cost, and intervention acceptance even among those at highest risk. Thus, the public health benefit of these interventions has yet to be fully realized. We hypothesize that this shortfall stems from multiple patient, provider and health system factors whose contribution to treatment and outcome variation is not yet understood. The proposed extension of AG 12262 entails four aims that will provide new information concerning variation in osteoporosis treatment and outcome. First, through surveys of patients and their healthcare providers, we will identify opportunities to improve intervention among elderly persons who have sustained a fracture; and will characterize correlates of long-term treatment continuation. Second, we will extend our study of fracture outcomes to a national sample to identify the patient, provider and health system attributes that contribute to variation in cost and adverse health outcomes. Third, we will develop a discrete state/event microsimulation model incorporating data from the first two aims to assess the cost-effectiveness of alternative osteoporosis interventions. This aim will also provide guidance to those planning future osteoporosis outcome studies through analyses addressing the correspondence between preference-based health outcomes measures and an osteoporosis-targeted health status instrument. Fourth, we will study the use of the microsimulation model as a tool for synthesizing evidence in patientcentered osteoporosis decision aids. Our proposed research will provide results useful in guiding both osteoporosis-related health policy and patient-centered decision making.

Project Title: EXERCISE--ADJUNCT THERAPY TO ESTROGEN IN OLDER WOMEN Principal Investigator & Institution: Dalsky, Gail; University of Connecticut Sch of Med/Dnt Bb20, Mc 2806 Farmington, Ct 060302806 Timing: Fiscal Year 2002 Summary: The central theme of this intervention development study is that regular exercise should be an adjunct therapy for older women to reduce the incidence of hip fracture. One out of every three white women 85 years and older are likely to experience a hip fracture, which leads to a loss of independence and a lower functional capacity. The primary approach for hip fracture prevention has been replacement estrogen. The long- range goal of implementing exercise as an adjunct therapy is to extend the time of first hip fracture by 5-10 years, resulting in a potential 30-50% reduction in hip fracture. The purpose of this intervention development study is to study the effects of participation in a three- year home-based exercise regimen for 105 women 65-78 years of age on risk factors related to bone and falling. An unique aspect of this study is that the volunteers will be long-term users of estrogen replacement therapy who have femoral neck bone mass >1 SD below the young adult level. The primary hypothesis to be tested is that women aged 65-78 years who are current users of estrogen replacement therapy and have low femoral neck bone mineral density will maintain sufficient compliance and retention in a 3 year home-based aerobic exercise and resistance training program to reduce risk factors regarding bone quantity and quality for osteoporosis, and falls. The specific aims to test this hypothesis are: 1) To evaluate the effectiveness of 3 year homebased exercise intervention on bone mass and geometric properties of the proximal femur. 2) To evaluate the effectiveness of home-based exercise intervention to improve formation relative to resorption, as evaluated by biochemical markers of bone

metabolism. 3) To evaluate the effectiveness of home-based exercise intervention on risk factors for falls (balance, muscular strength and endurance, gait, lean body mass). A multivariate repeated measures factorial analyses of variance will be done to determine changes in the outcome measures as influenced by the determinants of bone mass. This proposal will establish an exercise regimen that may be implemented as an adjunct therapy to estrogen in older women to preserve or improve bone strength to delay the onset of first hip fracture.

Project Title: FALL BIOMECHANICS AND HIP FRACTURE RISK Principal Investigator & Institution: Hayes, Wilson C.; Professor; Exercise and Sport Sciences; Oregon State University Corvallis, or 973391086 Timing: Fiscal Year 2002; Project Start 01-FEB-1994; Project End 31-MAY-2005 Summary: (Verbatim from the application) Falls and fall-related injuries are the most serious, common costly medical problems facing the elderly. In the US each year there are about 30 millions falls, or about 1 per second, among 10 million fallers. In addition, of the approximately 300,000 hip fractures that occur each year, over 90% are associated with falls. We have shown previously that falls to the side with impact on the hip are associated with more than 20-fold increase in the risk of hip fractures (compared to a 3fold increase in risk associated with reduced bone density). Thus, when screening for interventions and fracture prevention programs (pharmaceutical agents, trochanter padding or exercise), it is far less cost effective and efficient from a public health perspective to attempt to identify the 10 million elderly who will fall each year (which can now be done using relatively simple field tests) than it is to focus on the 500,000 to 600,000 elderly subjects who will fall to the side (for which comparable validated tests are not yet available). The aims of this competitive renewal application are focused on this goal. During the previous funding period, we completed the goals of Aim 1: Dynamics of Side Falls, demonstrating that slow gait speed and the postural disturbances of slipping or fainting are associated with falls to the side and impact on the hip. We have also developed the first available multi‑segment, whole body model for falling and showed it to be a powerful tool for studying the biodynamics of falling to the side. For our previous Aim 2: Side Fall Risk Index, we completed both the development and refinement phases of the proposed index, demonstrating that a linear combination of tandem gait, hip abduction strength, step velocity asymmetry from the quick-step test, and sway variables while standing in a semi-tandem position could be used to distinguish elderly subjects who fell to the side from those who fell in all other directions. Under our new proposed Aim 1: Validation of Side Fall Risk Index (SFRI), we will determine whether the Side Fall Risk Index we have developed during the previous funding period can be used prospectively to identify elderly subjects who will fall to the side. As an extension of our previous work on the dynamics of side falls, under Aim 2: Gait Variability as a Predictor of Side Falls we will analyze the ground pressure time histories of elderly fallers ambulating on an instrumented mat. We will apply modern signal analysis theory to the ground pressure time histories. Using chaos theory and fractal analysis and noting that cardiovascular and neuromuscular pathologies are characterized by increased regularity of heartbeat and gait, respectively, we will determine if gait parameters determined from ground pressure time histories can be used to identify frail elderly subjects who fall to the side.

Hip Fracture
Project Title: FOCUS Principal Investigator & Institution: Carson, Jeffrey L.; Richard C. Reynolds Professor of Medicin; Medicine; Univ of Med/Dent Nj-R W Johnson Med Sch Robert Wood Johnson Medical Sch Piscataway, Nj 088545635 Timing: Fiscal Year 2003; Project Start 01-SEP-2003; Project End 31-AUG-2008 Summary: (provided by applicant); Red blood cell transfusions are an extremely common medical intervention in both the United States and worldwide; over 11 million units are transfused in the United States. Between 60% and 70% of all blood is transfused in the surgical setting. Despite the common use of red blood cell transfusions, the threshold for transfusion has not been adequately evaluated and is very controversial. A decade ago the standard of care was to administer a peri-operative transfusion whenever the hemoglobin (Hgb) level fell below 10 g/dl (the "10/30 rule"). Concerns about the safety of blood, especially with respect to HIV and hepatitis, and the absence of data to support a 10 g/dl threshold led to current standard of care today to administer blood transfusions based on the presence of symptoms and not a specific Hgb/hematocrit level. However, there are no randomized clinical trials in surgical patients that have tested the efficacy and safety of withholding blood until the patient develops symptoms or the "10/30" approach to transfusion. Patients with underlying cardiovascular disease are at greatest risk of adverse effects from reduced Hgb levels. We propose to conduct a multi-center randomized trial to test if a more aggressive transfusion strategy that maintains postoperative Hgb levels above 10 g/dl improves patient outcome as compared to a more conservative strategy that withholds blood transfusion until the patient develops symptoms of anemia. Eligible patients for the trial will have undergone surgical repair for a hip fracture and have a postoperative Hgb level below 10 g/dl within three days of surgery. Only patients with cardiovascular disease will be entered into the study. Patients will be randomized to one of the two transfusion strategies. The 10 g/dl threshold strategy will use enough red blood cell units to maintain Hgb levels at or above 10 g/dl through hospital discharge. Symptomatic transfusion strategy patients will receive red blood cell transfusions for symptoms of anemia, although transfusion is also permitted but not required if the Hgb level falls below 8 g/dl. Outcomes will include functional recovery (primary outcome: ability to walk ten feet across a room without human assistance at 60-days postrandomization), long-term survival, nursing home placement, and postoperative complications (death in hospital or within 30 days, pneumonia, myocardial infarction, thromboembolism, stroke, delirium). We will randomize 2,600 patients from 25 centers over a 3.5-year period. This will allow us to detect a 16% relative risk reduction in the loss of ability to walk independently with power about 0.90. A pilot study in 84 patients demonstrated the feasibility of the study. Ambulation at 60 days is known to be highly predictive of ultimate functional outcome as well as of mortality at one year. Because inability to walk again has such important implications for quality office, and because, unfortunately, it is a common problem, it far outweighs the remote chance of viral infection or other complications from transfusion in these elderly patients. Also, this study will measure the frequency and 95% confidence intervals of the medical errors that are important in this patient population and are poorly documented in the literature. The medical errors that will be measured are: transfusion errors (blood transfusion to the wrong patient, mislabeling of samples for type and cross match, use of whole blood instead of packed red cells), failure to use thromboembolism prophylaxis, incorrect antibiotic prophylaxis, wrong site surgery and femoral shaft fracture.

Project Title: GENETIC ANALYSIS OF HIP FRAGILITY Principal Investigator & Institution: Turner, Charles H.; Professor; Orthopaedic Surgery; Indiana Univ-Purdue Univ at Indianapolis 620 Union Drive, Room 618 Indianapolis, in 462025167 Timing: Fiscal Year 2003; Project Start 04-APR-2003; Project End 31-MAR-2008 Summary: (provided by applicant): Genetic influences account for the majority of the population variance in bone mineral density and bone fragility. Considering that hip fracture is the most expensive of osteoporotic fractures, both in terms of health care cost and in human costs (i.e., morbidity and mortality), there should be considerable interest in an animal model for studying genetic influences on hip fragility. We recently
26
Hip Fracture
identified two strains of rats, Copenhagen 2331 (COP) and DA, which have considerable variation in the biomechanical properties of their femoral necks. We propose to use these rat strains to identify genes responsible for the variation in hip fragility. We will test three hypotheses: (1) COP and DA rats reach peak femoral neck strength and bone mass at six months of age. Our goal is to determine genetic influences on the biomechanical properties and bone structure at an age when femoral neck strength is at its peak. Sprague-Dawley rats achieve peak bone mass and strength within a window of 5-9 months of age. Presumably, COP and DA strains follow similar skeletal growth curves. We will measure femoral biomechanical properties, geometry and microstructure in rats ranging from 2 to 10 months of age to determine the age associated with peak values; (2) chromosomal regions harboring genes that regulate femoral neck strength and microstructure can be determined for rats. COP and DA progenitor rats will be mated and their F1 hybrid offspring intercrossed to create an F2 population containing 500-600 individuals. These rats will be phenotyped based upon femoral neck biomechanical, geometrical and microstructural measurements. Quantitative trait loci (QTL) analyses will be performed to identify the genetic loci influencing variation phenotypes. We anticipate that these analyses will identify several QTLs containing genes that influence femoral neck fragility; and (3) femoral shaft and neck fragility are regulated, at least in part, by different genetic loci. The COP x DA F2 population will be further characterized for bone fragility at the femoral midshaft QTL analyses will be performed to identify the genetic loci contributing to the variation in the phenotypes. We anticipate that these analyses will identify some QTLs previously linked to femoral neck fragility in Aim 2, as well as novel QTLs specifically influencing femoral shaft phenotypes.

Project Title: GENETIC REGULATION OF IGF-I IN PEAK BONE DENSITY OF MICE Principal Investigator & Institution: Rosen, Clifford J.; Director; Jackson Laboratory 600 Main St Bar Harbor, Me 04609 Timing: Fiscal Year 2002; Project Start 22-JUL-1998; Project End 31-MAY-2005 Summary: Insulin-like growth factor- I (IGF-I) is a ubiquitously expressed 7.5 kDa polypedtide that circulate in relatively high concentrations. In bone, IGF-I is secreted by osteoblasts, and is stored in the matrix bound to IGF binding proteins (IGFBPs). Skeletal IGF-I promotes osteoblast differentiation, increasing collagen biosynthesis and mildly enhancing bone cell mitogenesis. Reduced serum IGF-I concentrations have been linked to lower skeletal levels of this peptide, future risk of hip fracture, histomorphometric indices of bone formation, bone mineral density, and a poly-morphism in the IGF-I gene. Hence serum IGF-I has been considered an intermediate skeletal phenotype. In the first three years of our proposal, using inbred strains of mice have established: 1) serum IGF-I is a heritable polygenic train; 2) three major non-growth hormone dependent quantitative trait loci (QTLs) and one interactive QTL influence the serum IGF-I phenotype; 3) two IGF-I QTLs associate with major skeletal phenotypes (BMD and femoral length); 4) one QTL contains the IGF-I gene and the interactive QTL maps in close proximity to the IGFBP-3 gene; 5) congenic mice carrying one of these major QTLs exhibit reduced serum IGF-I and a major skeletal phenotype; and 6) osteoblasts from high serum IGF-I mice (C3H/HeJ) show a sixfold up-regulation in IGF-I exon 1 promoter mRNA compared to the low serum IGF-I mice (C57BL/6). These data suggest that IGF-I is important for the acquisition of BMD and optimal strength. In this proposal we hypothesize that serum IGF-I genes are also major determinants of skeletal IGF-I

expression. Our goals are to fine map these IGF-I regulatory genes and to understand how these genes affect osteoblast function and bone morphology. We propose three specific aims: 1) to delineate the genes for serum IGF-I by fine mapping and assessing nested congenics for changes in BMD and strength; 2) to determine the role of IGFBPs in modulating skeletal IGF-I by studying osteoblast expression and secretion of IGFBPs and by phenotype 'rescue' of newly developed congenics through targeted over expression of skeletal IGF-I; and 3) to determine the molecular mechanisms responsible for interstrain differences in skeletal IGF-I expression. These experiments will provide tremendous insight into the cellular regulation of the IGFs and IGFBPs, an important first stem towards understanding the role of IGF-I in osteoporosis and other chronic disease wherein tissue specific IGF-I activity may have a major pathophysiologic component.

Project Title: GENETICS OF BONE LOSS AND BONE STRENGTH IN MEN AND WOMEN Principal Investigator & Institution: Peacock, Munro; Professor; Indiana Univ-Purdue Univ at Indianapolis 620 Union Drive, Room 618 Indianapolis, in 462025167 Timing: Fiscal Year 2002 Summary: Osteoporotic fracture is due to age-related reduction in bone strength. Bone strength comprises bone mineral density, structure, quality and turnover, all of which are highly heritable. The most serious osteoporotic fracture occurs at the hip. Reduction in hip bone strength is due to a combination of low peak bone mass and age-related bone loss. Heritability of bone mass at the hip is high, but heritability of bone loss at the hip has not been studied. Women have lower bone strength and higher incidence of hip fracture than men. In men, heritability of bone strength has not been firmly established. Heritability of bone strength has been measured in 760 pairs of sisters, and a 10 cM genome screen has identified several chromosomal loci influencing bone strength. Two hypotheses will now be tested: 1. The rate of bone loss at the hip in women is genetically determined. This will be tested by remeasuring hip bone mass in 500 pairs of sisters in our current study and, if heritable, perform linkage analysis using genotypic already generated. 2. The genetic effect on bone strength in men is similar to that in women, but certain loci are sex specific. This will be tested by measuring bone strength in 700 pairs of brothers, comparing heritabilities to those in our 760 of sisters, and performing a genome screen to identify loci influencing bone strength in men. Three major goals in understanding the genetic basis of bone strength will be achieved: 1) establish if the rate of bone loss at the hip in women has a genetic component, and if so, localize the genes that underlie the loss; 2) establish heritabilities of bone strength in men and compare these with those established in women; 3) enrich our database for fine mapping bonestrength genes and establish if certain loci are sex specific. This information will lead to a much better understanding of the causes of osteoporotic hip fracture and of the difference in incidence between men and women and, ultimately, to new therapeutic and preventative treatments.

Hip Fracture
Timing: Fiscal Year 2002 Summary: Advancing age is associated with a reduction in skeletal muscle protein and muscle force production capabilities; a syndrome referred to as sarcopenia. This process occurs in healthy, normal aging, but is accelerated by physical inactivity, degenerative or other disease conditions. Incorporation of 13C-leucine into skeletal muscle protein, as measured by isotope dilution mass spectrometry, provides a measure of muscle protein synthesis. Decreased muscle mass and strength are associated with an increased risk of falling, and therefore, increased risk for hip fracture. Reduced muscle strength with aging can also result in physical disability and frailty, a loss of independent function, and contributes to escalating health care costs. The biological consequences of advancing age and the progressive decline in physical activity with age contribute to sarcopenia. Exercise training programs have the potential to improve overall fitness, muscle force generation, and imp rove quali ty of life. The physiological and functional benefits of increased muscular activity have been reported, even into the 9th decade of life (1). Thus, human skeletal muscle protein maintains the ability to respond to an exercise-induced increase in contractile activity throughout. The ability to adapt may be limited by other biological processes. Circulating concentrations and the pulsatile release patterns of several hormones that regulate metabolism are reduced with age. By virtue of their anabolic actions on body proteins, low serum growth hormone (GH), testosterone, dehydroepiandrosterone (DHEA), and perhaps estrogen, along with reduced insulin action, have all been implicated as mediators of the muscle protein wasting aging. We review the efficacy of recombinant human growth hormone (rhGH) replacement therapy and resistance exercise training to enhance muscle protein mass and contractile force output in elderly (62+ yr old) men and women.

Project Title: HEALTH CONCORDANCE IN OLDER MEXICAN AMERICAN COUPLES Principal Investigator & Institution: Peek, Mary K.; Preventive Medicine and Community Health; University of Texas Medical Br Galveston 301 University Blvd Galveston, Tx 77555 Timing: Fiscal Year 2003; Project Start 01-JUL-2003; Project End 30-JUN-2006 Summary: (provided by applicant): Individuals who are married tend to have lower mortality, morbidity, and better mental health. The potential protective effect of marriage on both physical and mental health is of particular importance to older couples as the number of older married adults rises and mortality rates continue to decrease. However, there is very little information on the connection between the health statuses of older married couples. The similarity between health of spouses, or "concordance" can be of particular importance if the deterioration in the health of one spouse is associated with the deterioration in the health of the other spouse. One way to address concordance is to examine the connection between one spouse's health events and the other spouse's health outcomes. To address the association between spouses' health more extensively, we intend to examine the potential influence of physical functioning and health events in one spouse on the health of the other spouse over a 2-5 year time period in older Mexican American adults. The specific aims of the study are: (1) to examine the relationship between the presence of major health events (myocardial infarction, stroke, cancer, and hip fracture) in one spouse and depressive symptoms and lower body mobility of the other spouse; (2) to assess the connection between physical functioning (e.g., I/ADL disability) in one spouse and depressive symptoms and lower body mobility of the other spouse; and (3) to investigate the association of mortality of

one spouse with depressive symptoms and lower body mobility of the other spouse. As a secondary aim, we will explore the possibility that social support and acculturation modify the relationship between spouses' health statuses in older Mexican Americans. We will be examining these specific aims in 553 married couples from the ongoing Hispanic Established Populations for Epidemiologic Studies of the Elderly (H-EPESE). One of the benefits of examining concordance in spouses' health in older Mexican Americans lies in their health profiles (mortality rates similar to older White adults but higher rates of certain diseases and disability). Structural equation modeling will be used for model estimation on three waves of data (1993-94 -1998/9.) Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: HIP OSTEOPOROSIS
RADIOGRAPHS:
NOVEL
METHOD
TO
DIAGNOSE
Principal Investigator & Institution: Arnaud, Claude D.; Professor Emeritus; Imaging Therapeutics, Inc. 1720 S Amphlett Blvd, St 240 San Mateo, Ca 94402 Timing: Fiscal Year 2003; Project Start 01-SEP-2003; Project End 28-FEB-2004 Summary: (provided by applicant): This Small Business Innovation Research Phase I project is designed to develop techniques for the diagnosis of osteoporosis and for assessing fracture risk by quantifying trabecular structural elements in hip x-rays. Osteoporosis is a public health threat for 44 million women in the United States alone. The inability to identify persons at risk for the disease is a major impediment in dealing with this epidemic. In fact, less than 30% of persons with osteoporosis are aware that they have it. This is due to the high cost and resulting small installed base of commercially available osteoporosis testing systems. Imaging Therapeutics Inc. proposes to develop technology for low-cost bone structural analyses by linking readily available x-ray equipment to novel image analysis algorithms. While measurements of bone mineral density (BMD) are easy to perform and are helpful in determining when to intervene therapeutically, low BMD accounts for only a portion of fracture risk. Progressive disruption of trabecular structure contributes the better part of the remainder of that risk. The aims of this proposal are: 1) To develop new image processing techniques for automated measurement of 2D-trabecular bone structural elements in hip radiographs. 2) To determine the influence of x-ray beam angulation, soft-tissue attenuation and radiographic technique on radiographic measurements of bone structure. 3) To determine the clinical validity of those 2 D measurements in vitro by a) comparing them, in cores of cadaver proximal femora, to similar measurements made using 3D micro CT and b) determining if they correlate significantly with biomechanical failure loads and stiffness. 4) To directly apply the technology developed in Phase I of this proposal to a series of clinical trials that will be developed for Phase II to prove the clinical utility of that technology in the diagnosis of osteoporosis and prediction of osteoporotic fracture.

negative patient outcomes. Yet, the use of physical restraints with frail older adults in hospitals persists. This study examines the impact of hospital organizational context and nurse staffing on restraint use and associated patient outcomes. Data on restraint use for hip fracture patients in hospital will be merged with American Hospital Association Annual Hospital Survey data on hospital characteristics and nurse staffing and extensive organizational data from surveys collected in several NINR-funded studies by Penn's Center for Health Outcomes and Policy Research. It is hypothesized that hospital nurse staffing and organization affect the rate of physical restraint use, and that such use is associated with poorer outcomes at discharge. My research to date has focused on patient characteristics associated with physical restraint. In order to achieve my long term goal to be an independent investigator in outcomes research regarding care of frail older adults. I need advanced training and mentoring in the requisite methodologies and analytic techniques used in the emerging field of outcomes research. With targeted training and conduct of this proposed study, I will gain a new research skill set in the design and analysis required to investigate the organization of nursing, manage large date sets, and analyze interactive effects of multiple variables on outcomes employing such methods as hierarchical linear modeling, censoring, and multiple imputation techniques. This proposed study is consistent with my goals to expand my clinical research into a new field of inquiry, nursing outcomes research, in which I have had no previous training or experience. My goal for this research career award are to: 1) gain a new research skill set in outcomes research, 2) extend my research program by examining the effects of hospital factors on physical restraint and other outcomes, 3) publish findings in peer- reviewed journals, 4) develop a proposal for extramural funding extending the scope of the study proposed here, and 5) establish interdisciplinary/collaborative relationships with experts in the field of outcomes research.

Project Title: INCIDENCE OF LATE MACULAR DEGENERATION IN OLDER WOMEN Principal Investigator & Institution: Coleman, Anne L.; Assistant Professor; Jules Stein Eye Institute; University of California Los Angeles 10920 Wilshire Blvd., Suite 1200 Los Angeles, Ca 90024 Timing: Fiscal Year 2002; Project Start 15-AUG-2002; Project End 31-JUL-2007 Summary: (Applicant's Abstract) Age-related macular degeneration is the number one cause of irreversible blindness in the United States and is more prevalent in older, Caucasian women. Although there have been several studies on the incidence of ARM, none of these studies has been able to provide accurate estimates on the incidence of late ARM and/or the progression of ARM in the oldest old, those individuals over 80 years of age, because of the limited sample sizes in these studies in this age group. The population in the Study of Osteoporotic Fractures (SOF) is an appropriate cohort in which to evaluate the incidence of late ARM and the progression of ARM, because the mean age of the women at the re-examination will be 84.4 years of age and the sample is mainly Caucasian. The proposed research study aims to determine the incidence of late ARM, the rate of progression of ARM, and the association of specific risk factors such as diabetes mellitus and prior cataract surgery with late ARM and the progression of ARM in elderly women. In addition, it aims to determine the trajectory of visual decline in older women over a 14- year period. Secondarily, it aims to determine the impact of late ARM on vision-targeted health-related quality of life and to determine whether or not an association exists between the progression of ARM and the risk of falling and hip/non-spine fractures. In 1997 to 1998 (Visit 6), 5482 women had an eye examination that consisted of a medical and ocular history, nine questions from the National Eye Institute Visual Function Questionnaire (NEI-VFQ), and measurements of visual acuity, contrast sensitivity, peripheral vision with automated perimetry, intraocular pressure, and uncorrected refractive error. These women also had a refraction and imaging of their lenses and fundi of both eyes through dilated pupils. Approximately 4.5% of these women have photographically validated late ARM, 41.5% have early ARM, and 54% have no ARM or hard drusen only. In the proposed re-examination, we will update their medical and ocular history and ask them the nine questions from the NEIVFQ. In addition, visual acuity and contrast sensitivity will be re-measured. Fundus photographs of both eyes through dilated pupils will be obtained. These photographs and the relevant photographs from 1997 to 1998 will be graded for ARM with the Wisconsin Age-Related Maculopathy Grading System (WARMGS) in a masked fashion so that the readers do not know which film is from which visit. The University of Wisconsin will also grade the fundus photographs on 30% of the eyes with ARM and 10% of the total sample. This will allow the identification of women in SOF who have had progression of their ARM and developed late ARM since 1997 and 1998.

Project Title: INDEPENDENT SCIENTIST AWARD Principal Investigator & Institution: Ottenbacher, Kenneth; Associate Director; Sealy Center on Aging; University of Texas Medical Br Galveston 301 University Blvd Galveston, Tx 77555 Timing: Fiscal Year 2003; Project Start 01-MAY-2003; Project End 30-APR-2008 Summary: (provided by applicant): The candidate (Kenneth J. Ottenbacher) holds a faculty position at the University of Texas Medical Branch (UTMB) in Galveston, Texas, that involves several administrative roles including: Vice Dean in the School of Allied Health Sciences, Director of the Division of Rehabilitation Sciences, and Associate Director of the Sealy Center on Aging. The K02-Award will allow Dr. Ottenbacher to reduce his administrative responsibilities and focus additional time on research. K02 funding will permit him to expand his examination of the disablement process in older adults. His current research is funded by grants from the National Institute on Aging and, more recently, the American Heart Association. Specifically, Dr. Ottenbacher will systematically explore the relationship between functional status and two components of the disablement process associated with quality of life - patient satisfaction and participation in community and social/personal activities (as defined in the World Health Organization's, International Classification of Functioning, Disability and Health). The immediate goals for the K02 include: 1) reduce administrative responsibilities to a less than 25% time commitment, 2) increase publication rate by 20% per year for the next four years, and 3) increase amount of externally funded grant dollars by 100% by end of K02-award. These goals will be accomplished by permanent resignation of his administrative role as Vice Dean in the School of Allied Health Sciences and reassignment of other responsibilities, including transferring management of a Health Services Resources Administration training grant, for which he is currently PI, to another faculty member. These changes will allow Dr. Ottenbacher to devote a minimum of 75% time to research and achieve his long term goals of establishing a program of externally funded research supported by multiple R01 type grants that contributes to the understanding of older adults with disabilities.

Principal Investigator & Institution: Fleet, James C.; Associate Professor; Foods and Nutrition; Purdue University West Lafayette West Lafayette, in 479072040 Timing: Fiscal Year 2004; Project Start 15-SEP-1997; Project End 30-JUN-2008 Summary: (provided by applicant): The control of intestinal calcium absorption is important for human health in two ways. First, the risk of osteoporotic hip fracture is higher in women with low calcium absorption efficiency and this may be due to ageassociated calcium malabsorption or intestinal resistance to 1,25(OH)2 vitamin D3 (1,25(OH)2 D, the primary regulator of intestinal calcium absorption). Second, a significant barrier to the use of vitamin D analogs as pro-differentiating agents in cancer treatment is that they stimulate intestinal calcium absorption and cause hypercalcemia. Our long-term objective is to clarify the mechanisms used by 1,25(OH)2 D to promote calcium absorption and to utilize this information to improve calcium absorption in people with low fractional calcium absorption and to aid in the design of vitamin D analogs that can be used as non-calcemic cancer therapeutics. New research shows that 1,25(OH)2 D rapidly activates second messenger and kinases pathways including the MAP kinases and their upstream activators; inhibition of these kinases blunts 1,25(OH)2

D-mediated gene transcription indicating the classical and non-classical vitamin D signaling pathways interact. The goal of the proposed research is to determine how the 1,25(OH)2 D-mediated transcriptional activation of intestinal calcium absorption is influenced by the basal or induced activity of the MAP kinases ERK1 and 2. The specific aims of this project are to: (1) Identify the nVDR-mediated genomic pathways controlling intestinal calcium absorption that are modulated by 1,25(OH)2-induced activation of ERK1 and 2, and (2) Establish the protein-protein interactions necessary for 1,25(OH)2 D-mediated gene expression that are promoted by 1,25(OH)2 D-induced ERK1 and 2 activity. We will accomplish these aims by studying the effect of 1,25(OH)2 D in a well-characterized cell culture model (Caco-2 cells) and in the small intestine of mice. Biological actions of 1,25(OH)2 D will be studied in the presence of activators and inhibitors of protein kinases (pharmacologic inhibitors, dominant negative kinases) and the rapid actions of vitamin D (vitamin D analogs), nVDR action and function will be studied with cellular imaging, reporter genes, multi-hybrid assays, and chromatin immunoprecipitation (CHIP) assays. Elucidating the mechanism of this vitamin D signal pathway cross-talk will provide the foundation for controlled modulation of intestinal calcium absorption, e.g. when vitamin D resistance associated with aging or estrogen deficiency is present.

Project Title: LEAD EFFECTS ON SKELETAL STEM CELLS AND FRAC Principal Investigator & Institution: Schwarz, Edward M.; Associate Professor; University of Rochester Orpa - Rc Box 270140 Rochester, Ny 14627 Timing: Fiscal Year 2002; Project Start 01-JUL-2002; Project End 30-JUN-2006 Summary: (provided by the applicant): The unifying hypothesis of this Program Project is that Pb exposure causes osteoporosis, which at the cellular level is known to be the result of an imbalance between bone resorption and bone formation. This condition is also associated with defective skeletal repair, which represents a significant component of the disease, as it has been shown that ~24% of osteoporosis patients that sustain a hip fracture die from associated complications. Critical data in support of this theory are that animals feed Pb in their diet become osteoporotic. At present the mechanism of this Pb-induced osteoporosis and the effects of Pb on fracture healing are unknown. This project will test the hypotheses that 1) Pb-induced osteoporosis is caused by preferential inhibitory effects on bone stem cells (osteoblast >>osteoclast progenitors) and 2) this inhibition has significant effects on skeletal repair (fracture healing). To test this the investigators will utilize two different Pb exposure regimens: Chronic Pb exposure (adult mice continually fed Pb in their drinking water) and osteoporosis-induced exposure (adolescent mice are exposed to Pb during development to incorporate Pb into their bones following 2 month of a Pb free diet, to clear the systemic Pb, the mice are overiectomized to commence the osteoporosis-induced exposure). Utilizing these exposures regimens with the dosing of 0,200 or 500ppm of Pb in their drinking water, to achieve a blood Pb concentration of (<5, 15, and 40ug/dl respectively), the investigators will evaluate the effects of Pb on bone stem cells (Aim 1) and fracture healing (Aim 2). The effects of Pb exposure on osteoblast progenitor cells will be analyzed in nodule formation, alkaline phosphatase, and gene expression assays on primary bone marrow cells from mice. Effects on osteoclast progenitor cells will be evaluated in splenocyte CFU-M colony and osteoclastogenesis (TRAP) assays to determine osteoclast precursor frequency; and bone wafer resorption assays to evaluate effects on osteoclast activity. The effects of Pb exposure on fracture healing will be evaluated utilizing a stabilized

Project Title: LOCUS OF CARE & PRESSURE ULCERS AFTER HIP FRACTURE Principal Investigator & Institution: Baumgarten, Mona; Associate Professor; Epidemiology and Prev Medicine; University of Maryland Balt Prof School Baltimore, Md 21201 Timing: Fiscal Year 2002; Project Start 30-SEP-2001; Project End 31-AUG-2005 Summary: (Taken from the application): There have been enormous changes in the care of hip fracture patients in recent years, including improved surgical techniques, earlier surgical repair, and earlier postoperative weight bearing. Since the advent of prospective payment to hospitals, the length of hospital stay for hip fracture has decreased dramatically and there has been a large increase in the variety of postacute care settings to which patients are discharged. Yet, nothing is known about the impact of these changes in locus of care on patient outcomes. Our goal is to study one such outcome (pressure ulcers) among elderly hip surgery patients in the current health care environment. The specific aims of this study are to estimate the incidence of pressure ulcers among elderly patients who have undergone surgical repair for hip fracture; to compare care settings (e.g., acute care hospital, onsite subacute unit, rehabilitation facility, nursing home, home) with respect to the incidence of pressure ulcers and with respect to use of pressure ulcer prevention measures; to assess the relationship between the incidence of pressure ulcers and certain characteristics of the early postfracture period (e.g., length of time waiting before transport to hospital; length of stay in the Emergency Department); and to develop a predictive model relating patient characteristics and characteristics of the postfracture period to individual patients risk of pressure ulcers. To achieve the research aims, a prospective cohort study will be carried out in eight hospitals that are part of the Baltimore Hip Studies network. The cohort will be made up of 1,240 eligible, consenting patients aged 60 years or more who undergo surgical repair of hip fracture. All patients will undergo a full-body skin inspection on admission and on alternating postoperative days, up to the 21 St postoperative day. If the patient is discharged home or to a postacute setting in the course of the follow-up period, the skin exam will be performed in the new setting. Additional data will be obtained by interview and chart review. The incidence of pressure ulcers per person-day of follow-up will be estimated overall and separately for each type of care setting. Discrete time proportional hazards models will be used to identify risk factors that are associated with increased pressure ulcer rates and to develop a statistical model for predicting patients individual risks. Pressure ulcers represent a significant problem both in terms of patient suffering and cost of care. By identifying settings, characteristics of the postfracture period, and patient characteristics that are associated with especially high risk, the proposed study will provide information for clinical practice, health care planning, and the development of future clinical trials.

Summary: (provided by applicant) This study will be conducted among a large multiethnic cohort (N = 11,432) from the nationwide Women's Health Initiative (WHI), which includes an observational study and three clinic trials. The age range of this cohort is between 50-79 years at the baseline, and it has multiple minority groups: 1583 black, 739 Hispanic and 149 Native American women. The maximal follow-up time of this cohort will be 9 years by 2005. Dual-energy x-ray absorptiometry (DXA) is used to measure bone mineral density (BMD) and body composition. The randomized clinical trials and longitudinal nature of the WHI study provide a unique opportunity to investigate: 1) treatment effects of hormone replacement therapy (HRT) and calcium and vitamin D supplementation on hip structural geometry; 2) longitudinal changes in skeletal muscle mass as a factor in hip fragility; and 3) ethnic differences of mean and rates of changes in hip geometry and muscle mass. Special computer software will be used for analyzing hip scans by dual-energy x-ray absorptiometry (DXA). Crosssectional area, subperiosteal width, estimated endocortical diameter, estimated mean cortical thickness, buckling ratio and section modulus at the femoral neck, at the intertrochanteric and the femoral shaft regions will be assessed. MRI scans will be used as references to calibrate total, appendicular and leg skeletal muscle measurements from DXA subregion analyses. Prevalence rates of sarcopenia (low muscle mass) among each age and ethnic group will be studied. Random Effects Models will be used to analyze the longitudinal data. This proposed study is not funded by the WHI program. Recourses that the WHI will provide include DXA scans, fall and fracture data, and information on covariates. Since the majority of data collection work has been or will be done by the WHI, we will be able to cost effectively test multiple important scientific hypotheses in this study. The novel approaches in this ancillary study will enhance scientific contributions of the WHI program. The significance of the proposed study is that it may demonstrate the utility of bone structural analysis in addition to bone mass measurements for understanding ethnic differences in fracture risk and/or for assessing the effect of pharmacologic therapy (i.e. HRT) on bone health. Furthermore, if the muscle variables are found to be a strong determinant of bone structure in the proximal femur and the risk of fall, then it may be important to develop interventions to increase muscle mass in this region to prevent hip fracture.

Project Title: MEASUREMENT OF THICKNESS/DENSITY OF THE PROXIMAL FEMUR Principal Investigator & Institution: Prevrhal, Sven; Radiology; University of California San Francisco 500 Parnassus Ave San Francisco, Ca 941222747 Timing: Fiscal Year 2003; Project Start 01-APR-2000; Project End 31-MAR-2005 Summary: (Taken from the application): Hip fracture is one of the most severe implication of Osteoporosis, a disease affecting millions of elderly people world-wide. The clinically established method to predict a person's hip fracture risk, bone densitometry, cannot separately measure the status of trabecular and cortical bone but only reports overall bone density. There is evidence that both compartments individually contribute to bone strength but are differently affected by aging or osteoporotic changes and therapeutic regimens. This research effort will approach the following questions: Can the density and the thickness of cortical bone in the proximal femur be measured accurately with volumetric Quantitative Computed Tomography (vQCT)? Does the knowledge of these parameters aid in predicting mechanical integrity in addition to standard bone densitometry? To what extent is the technique applicable in vivo? To assess the accuracy of vQCT, a comparison to Micro-CT is planned. Micro-CT

Hip Fracture
is a Computed Tomography technique on microscopic level (the spatial resolution is 25 mm for the instrument being used) and has recently been extended to scan whole proximal femora. It can therefore be used as a gold standard to evaluate vQCT. Out of a total of 25 excised cadaveric proximal femora from elderly women who did not have diseases known to affect bone, 5 will be scanned with vQCT and Micro-CT. The analysis tools, which will comprise segmentation of the cortical wall and local measurement of cortical bone mineral density and thickness, will be applied to both data sets. The other 20 specimens will be subjected to vQCT, standard bone densitometry and mechanical testing. During the latter, bone elasticity and ultimate failure load will be recorded. The gathered data will allow to estimate the relative contribution of the cortical thickness and density to mechanical integrity and to locate the most sensitive regions of the cortex. The question of whether a vQCT scan of cortical bone can add information to standard bone densitometry can also be answered. The third part of the study will focus on clinical feasibility of vQCT of cortical bone. Its specific aim is reducing the radiation exposure by limiting the CT scan volume and decreasing the amount of radiation used. By analyzing the impact of the consequential increase of image noise and loss of spatial resolution on the measurability of cortical density and thickness optimal CT imaging parameters will be derived.

Project Title: MINORITY PREDOCTORAL FELLOWSHIP PROGRAM Principal Investigator & Institution: Yim-Chiplis, Paula K.; None; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2003; Project Start 16-FEB-2003; Project End 15-FEB-2005 Summary: (provided by applicant): Maintaining postural balance is crucial to mobility. Mobility disability is predictive of more severe disablement, including falls, hip fractures, recurrent hospitalizations and institutionalization. Approximately half of persons 65 years or older report a fall annually and $10 billion is spent for the care of hip fractures each year. An important national health goal is to "help individuals of all ages increase life expectancy and improve their quality of life." Identifying modifiable health factors that can delay the onset or decrease the slope of functional decline relating to balance is of key importance. The purpose of this study is to determine the association of knee extensor strength, body composition, and physical activity with balance in healthy adults. This study is a substudy of a NASA/National Institute on Aging (NIA) study. Specific questions are: 1). Is there a difference between same-age gender groups in balance? 2). Will knee strength predict balance after accounting for body composition and physical activity? 3). Do knee extensor strength, body composition and physical activity decrease the association of age with balance? 4). Does physical activity have an independent contribution to balance? Using a cross-sectional design, 180 healthy men and women from 20-90 years of age belonging to the Baltimore Longitudinal Study of Aging (BLSA) will undergo evaluations of balance using the modified "Equitest"; knee muscle strength using the "KinCom" dynamometer; body composition using dualenergy x-ray absorptiometry (DEXA) scanning; and physical activity assessment using a questionnaire. Results using sequential regression analysis, ANOVA, and ANCOVA will determine the importance of these health factors throughout the lifespan.

Project Title: MULTIAXIAL STRENGTH BEHAVIOR OF HUMAN TRABECULAR BONE Principal Investigator & Institution: Keaveny, Tony M.; Professor; Mechanical Engineering; University of California Berkeley Berkeley, Ca 947205940 Timing: Fiscal Year 2002; Project Start 01-AUG-1996; Project End 31-JAN-2004 Summary: In this grant, we continue to investigate the multiaxial failure behavior of human trabecular bone. The clinical motivation is to improve mechanistic understanding of osteoporotic hip fractures. So far, we have described the failure behavior of trabecular bone for the human proximal femur, tibia, and vertebral body (n=214, each with a high-resolution three-dimensional reconstruction) for habitual type loading. We found that the strains at which the bone fails are relatively independent of volume fraction, but can differ across sites. The difference between tensile and compressive failure strains is greater in the higher density bone of the femoral neck. These results suggest that micro-structural bending of individual trabeculae dominates failure mechanisms at low density, but becomes less important at high density. Our work on axial-shear mutliaxial testing demonstrated that engineering type multiaxial failure criteria-expressed in units of strain-can predict the experimental behavior very well despite variations in volume fraction and anatomic site, with mean errors between experiment and criterion of less than 1 percent. These findings provide the foundation for more advanced research on multiaxial failure behavior. Given the difficulty of performing the requisite multiaxial experiments on relatively scarce human tissue, we propose to combine sophisticated computer simulations of the micro-mechanical failure mechanisms of trabecular bone with selected multiaxial experiments to develop a complete multiaxial failure criterion for femoral (neck and trochanter) trabecular bone. Specifically, we hypothesize that multiaxial failure of femoral trabecular bone is determined by critical strain levels and is independent of volume fraction. Highresolution micro-mechanical computer models, using 3D images obtained to date, will be used to simulate multiaxial behavior. These models will be first calibrated against our existing experimental data and then used to predict a wide variety of states of multiaxial failure. The predictions will be validated by new multiaxial experiments (n=100). The validated criterion will then be analyzed for a dependence on volume fraction. To address clinical significance, we also hypothesize that this multiaxial behavior is an independent determinant of whole bone femoral strength. To test this, anatomically detailed finite element models will be developed of the whole proximal femur using computed tomography and magnetic resonance scans. Simulations will be done with and without inclusion of the multiaxial failure criterion, and these predictions will be compared against experimental data for 20 cadaver bones. This work should provide substantial insight into mechanisms of whole bone and trabecular bone failure under traumatic conditions. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: NIA DEVELOPMENT AWARD PAIN AND DELIRIUM IN HIP FRACTURE Principal Investigator & Institution: Morrison, Sean; Medicine; Mount Sinai School of Medicine of Nyu of New York University New York, Ny 10029 Timing: Fiscal Year 2002; Project Start 01-JUL-1998; Project End 30-JUN-2003 Summary: Dr. Morrison's interest in quality of life issues at the end-of-life has led him to focus on palliative care and geriatrics. Merging these two areas, his clinical and research work suggest that pain symptoms tend to be overlooked in patients presenting with

dementia/delirium. Dr. Morrison's long-term objectives are to promote understanding of this issue and to enhance the quality of life of older patients through improved pain and symptom management. The overall objective of the research project is to examine the management of pain in hip fracture patients and the inter-related problem of delirium. The specific aims are to: determine the incidence and prevalence of pain and delirium in patients with hip fracture; describe the management of pain and delirium; identify risk factors for the development of delirium and for inadequate pain management; examine the relationship between delirium and pain on select patient outcome variables; and develop strategies and interventions to improve the management of delirium and pain. Patients entering the Mount Sinai Health System presenting with a hip fracture will be studied. All patients will be assessed daily through the fifth hospital or third full post-operative day and thereafter every other day through the ninth hospital day for the severity of their pain and for delirium. Information will be collected on specific processes of care that are used during the treatment course of these patients with particular attention to those processes that could lead to the development of pain or delirium and those directed at the management of these two conditions by concurrently following the course of the patients and by reviewing medical records. Patients will be followed longitudinally through their hospitalization and at 2 and 6 months with assessments of pain, functional status, morbidity, and mortality. In the final half of the five year project, the data collected from the initial phase of this proposal will be used to plan and test two interventions at the Mount Sinai Hospital. The first intervention will be directed at improving pain management. The second intervention will be randomized controlled trial evaluating the pharmacologic management of delirium. Dr. Morrison will engage in a number of educational activities in order to enhance his research and statistical analysis skills. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: NURSING INTERVENTIONS & OUTCOMES IN 3 OLDER POPULATIONS Principal Investigator & Institution: Titler, Marita G.; Director of Research, Quality; None; University of Iowa Iowa City, Ia 52242 Timing: Fiscal Year 2002; Project Start 01-JUL-2001; Project End 31-MAR-2005 Summary: (provided by applicant): As competition for health care services increase, understanding the relationships among interventions and patient outcomes is essential. Nursing interventions are not accounted for in standardized coding schemas, and, thus, are rarely included in outcomes effectiveness studies that use large electronic data sets. The recent implementation of standardized classification systems of nursing interventions, such as the Nursing Interventions Classification (NIC), now makes it possible to describe the contributions of nursing care to patient outcomes. Research in this area has been limited due to availability of clinical data repositories that include nursing care variables. The site for this proposed study, the University of Iowa Hospitals and Clinics (UIHC), has a large electronic database of nursing interventions accumulated over 3 years that can be accessed and linked, at the individual patient level, to other clinical and operational data. The purpose of this 4-year exploratory study is to evaluate a methodological approach for conducting nursing outcomes effectiveness research using existing clinical and operational data that reside in several electronic data repositories in a large academic medical center. Specific variables will be identified and examined in three elderly patient groups: DRG 127 - Heart Failure and Shock, DRG 209 Major Joint and Limb Reattachment Procedures of the Lower Extremity (Hip Fracture), and those who are recipients of the nursing intervention Fall Prevention.

and results of this study will be used to formulate a guideline for investigators on the construction and use of a nursing effectiveness research database built from electronic data repositories. The study's four aims are to: Identify the most frequently used nursing diagnoses, nursing interventions, pharmacological treatments, and medical treatments for the hospitalized elderly with DRG 127 or 209, and for those who receive the NIC intervention of Fall Prevention. Describe the relationships among patient characteristics, patient clinical conditions (nursing diagnoses, medical diagnoses, severity of illness), treatments (nursing interventions, medical treatments, pharmacological treatments), characteristics of nursing units, and outcomes of hospitalized elderly patients (DRG 127; DRG 209, Fall Prevention) using a cross sectional, retrospective design. Compare the cost of acute care for patients a) who receive of the nursing treatment Fall Prevention with those who do not receive this nursing intervention, b) who receive the most frequently used nursing treatment for heart failure (DRG 127) with those who do not receive this intervention, and c) who receive the most frequently used nursing treatment for hip fracture (DRG 209) with those who do not receive this intervention. Develop a guideline for construction and use of a nursing effectiveness research database built from electronic data repositories.

Project Title: OSTEOPOROSIS CANDIDATE GENES: IN SILICO AIDED DISCOVERY Principal Investigator & Institution: Ardlie, Kristin G.; Genomics Collaborative, Inc. 99 Erie St Cambridge, Ma 02139 Timing: Fiscal Year 2003; Project Start 30-SEP-2003; Project End 30-SEP-2004 Summary: (provided by applicant): Our understanding of the gene interactions that underlie molecular pathogenesis is expanding rapidly, yet despite continuing technical advances in the area, genetic studies of common diseases remain costly and time consuming. Initial linkage and/or genome scan studies are rarely definitive, and require further focused genetic follow-up and/or validation studies often on additional patient cohorts. Current solutions include sample pooling to defray the considerable genotyping costs of whole genome studies, or reduced and selective focal candidate gene approaches. The success of the latter, however, depends on knowledge of the disease and pathways, which is growing but still limited. Our goal is to determine whether simulating the biological pathways of putative candidate genes prior to testing those candidates, can enable us to more accurately target higher-likelihood candidates and reduce both the cost and time involved in identifying the genes associated with disease, as well as to define the likely role of these targets in a future diagnostic or therapeutic setting. We will test this in a genetic study of Osteoporosis aimed at identifying the gene(s) underlying the observed linkage to chromosome 1p36. Osteoporosis is a disease of reduced bone mineral density (BMD) that is associated with increased risk of bone fracture and for which the treatment and care of hip fractures exceeds $9 billion annually. Numerous twin and family studies have shown that as much as 80% of the individual risk in BMD is under genetic control. Moreover the genetic basis of the disease is likely to be polygenic, involving multiple gene products implicated in both bone modeling (growth) and remodeling (loss and gain). Our goals in this phase of the study are 1) to evaluate all genes in the linkage region 1p36 in a novel biological modeling and simulation platform, "BoneFusion", for their impact and importance in bone remodeling, 2) to genotype SNPs in the genes identified as high value candidates in order to identifying associations between the gene candidates and osteoporosis, and test the model, and 3) to further use the BoneFusion computer

Project Title: OUTCOMES ASSOCIATED WITH ANTIEPILEPTIC DRUGS IN ELDERLY Principal Investigator & Institution: Garrard, Judith M.; Professor; University of Minnesota Twin Cities 200 Oak Street Se Minneapolis, Mn 554552070 Timing: Fiscal Year 2002; Project Start 30-SEP-2002; Project End 31-AUG-2003 Summary: Elderly people (age 65 years and older) are the most rapidly growing segment of the US population and the incidence of epilepsy is greatest in this age group. Little information is available about the use or outcomes associated with antiepileptic drugs (AEDs) by these vulnerable persons. We will examine pattems of AED use and associated outcomes among nursing home (NH) and community based elderly. For the proposed research, we have available two large electronic data sets: (1) the Beverly Enterprises Inc. centralized records (the Minimum Data Set and physicians' orders) for two calendar years (1999, 2000) for all residents (N~140,000 for two years) living in 501 NHs in 31 states, and (2) the Health Care Financing Administration's (HCFA) integration of the Medicare Current Beneficiaries Survey with Medicare claims files (N~12,000 elderly per year) for 7 calendar years. Both of these data sets have been used in part during the current project (1997-2002) by the same multidisciplinary team that will be working in the proposed project. We have a thorough working knowledge of the complexities of these data sets and the richness of information they contain. In our current research, we found a prevalence of 7.7% for AED use by NH admissions. Significant covadates with AED use at admission were epilepsy/seizure, bipolar depression, age group, and cognitive performance. During the first 3 months following admission, an additional 2.7% people were initiated on AEDs. Epilepsy/seizure indication was present in 5.8% of all admissions and an additional 1.47% of the followup cohort during the first 3 months. Specific aims of the proposed project are: (1) outcomes associated with any AED use by eldedy, (2) pharmacoepidemiology, characteristics, and outcomes associated with CBZ, PHT and VPA, and (3) the pharmacoepidemiology of other specific AEDs. Patient outcomes will be captured through incidence events, while AED use can be tracked continuously over time. Multivariate-modeling techniques will be used, controlling for demographics, comorbidities, and regional effects. Other P50 teams are studying the elimination kinetics of AEDs, and we will use this knowledge to develop age, gender and co-medication specific estimated total and unbound concentrations for NH residents.

osteoporosis or low bone mass, resulting in 1.5 million fractures per year, including 300,000 hip fractures, 700,000 spine fractures, 250,000 forearm fractures, and 250,000 fractures at other sites. While traditionally considered a disease of women, men also develop osteoporosis. Thus, at age 50, the lifetime risk of an osteoporotic fracture in women is 40%, and the comparable figure for men is 13%. Given the scope of this problem and the projected increase in the prevalence of this disease as the population ages, rational approaches to prevention and treatment depend critically on gaining a better understanding the pathogenesis of this disorder, as well as assessing its impact in the community. Work over the previous funding cycle has now identified estrogen (E) deficiency as a key factor in the development of age-related bone loss not only in women, but also in men; hence, a theme common to all projects is E regulation of bone metabolism. As in the past, the major strength of our group is to bring together diverse disciplines into synergistic interactions, and the present application spans the spectrum from population-based epidemiology studies, intensive studies in the clinical research center, animal studies using novel mouse knock out models, and basic molecular studies using state-of-the-art proteomics technology. This is accomplished through five Projects and an Administrative and Biostatistics Core: Project 1, "Pathophysiology of Osteoporosis in Aging Men" and Project 2, "Pathophysiology of Osteoporosis in Aging Women" utilize intensive studies in the clinical research center in men and women, respectively; Project 3, "Risk Factors for Hip Fractures Among the Elderly" utilizes the resources of the Rochester Epidemiology Project in population-based epidemiology studies; Project 4, "Estrogen Receptor Coactivators and Bone Metabolism" focuses on novel mouse knock out models with defects in E action; and Project 5, "Actions of Estrogen Receptor Coregulators in Osteoblasts" proposes to dissect E action in bone cells at a molecular level. Collectively, these studies strive to provide a comprehensive assessment of the pathogenesis and clinical impact of this important disorder.

Lower serum testosterone concentrations have been associated with important health consequences, including reduced bone mineral density, increased risk of hip fracture, loss of muscle mass, decreased libido and fertility, and increased cardiovascular disease. HYPOTHESIS I will test whether glucocorticoids mediate down- regulation of urea transporter proteins by altering transcription. Specific Aim 1 will test whether glucocorticoids down-regulate UT-A and/or UT-B protein or mRNA expression. Specific Aim 2 will determine the element mediating glucocorticoid-induced suppression of urea transporter promoter activity. HYPOTHESIS II will test whether chronic lithium administration down-regulates urea transporter protein(s) by increasing glucocorticoids. Specific Aim 3 will test whether adrenalectomy prevents long-term down-regulation of urea transporter protein(s) in lithium-treated rats. Specific Aim 4 will test whether elevated lithium levels perturb urea transporter phosphorylation or function in rat inner medulla or in EcR-293 cells that have been stably transfected with a specific urea transporter isoform. HYPOTHESIS III will test whether urea transporter proteins are down- regulated during aldosterone-escape. Specific Aim 5 will test whether mineralocorticoids down-regulate UT-A and/or UT-B protein or mRNA expression.

Project Title: PREVENTION OF FUNCTIONAL DISABILITY IN AT RISK ELDERS Principal Investigator & Institution: Gill, Thomas M.; Associate Professor; Internal Medicine; Yale University 47 College Street, Suite 203 New Haven, Ct 065208047 Timing: Fiscal Year 2002; Project Start 01-JAN-1998; Project End 31-DEC-2002 Summary: (Adapted from applicant's abstract). According to the applicant intervention strategies to date have focused largely on the restoration of function among disabled elderly persons in the context of rehabilitation after an acute medical event, such as a stroke or hip fracture. There have been few attempts to develop strategies aimed at "prehabilitation" (PREHAB), which is the prevention of functional dependence and decline among persons who have not sustained an acute illness or injury. The overall objective of this project is to test the efficacy of a home-based PREHAB strategy to prevent functional decline in a high-risk group of physically impaired, communityliving elderly persons who do not have severe memory loss or impaired orientation. Community-living persons, over 75 years will be screened for eligibility during nonurgent clinic visits at two large primary care sites. After comprehensive home assessment, 160 physically impaired elders will be randomized, using a blocked design that is stratified by clinic site, severity of physical impairment, and age to receive either the control group strategy (EDUCATE), a 6-month education program covering several content areas in general health practices and health promotion, or a home-based intervention strategy (PREHAB) -- which is a 6-month training program of physical therapy, to include muscle strengthening, joint range of motion, foot care, and balance, gait, transfer, and stair training, plus functional therapy to include training and instruction in safe and effective performance of the task needed to complete ADLs and selected IADLs, provision of appropriate adaptive equipment, and environmental modifications. Functional assessments will be completed in all participants at baseline and at six and twelve months by trained staff who will be kept unaware of group assignments. The specific aims of the project are 1) to determine whether the homebased PREHAB strategy is superior to the EDUCATE strategy in preventing decline in ADL-IADL function, and in decreasing the use of formal and informal care, including home care and nursing home care; 2) if the PREHAB strategy proves successful to

identify the predictors of response to the intervention and to determine whether its benefit is mediated, as hypothesized, by improvements in both physical capability and functional self-efficacy. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: PROPOXYPHENE USE IN THE AGED: PREDICTORS AND OUTCOMES Principal Investigator & Institution: Kamal-Bahl, Sachin; Pharmaceutical Health Services Research; University of Maryland Balt Prof School Baltimore, Md 21201 Timing: Fiscal Year 2003; Project Start 15-APR-2003; Project End 14-JUL-2004 Summary: (provided by the applicant): Over the past two decades, studies have documented a high prevalence of potentially inappropriate drug use among the elderly. Inappropriate drug use is defined in several ways; the most widely accepted explicit criteria are those developed by Beers (1997). Propoxyphene, an opiate analgesic, is one such inappropriate medication identified by the Beers' criteria. Its use is associated with such adverse effects as sedation and dependence, and it has no efficacy advantages over other analgesics. The CNS-related side effects with propoxyphene use may increase the likelihood of falls and, hence, of fall-related fractures in the elderly. Despite this, propoxyphene is the most prevalent among all inappropriate drugs used by the elderly according to a recent study by AHRQ. Prior research of propoxyphene use in the elderly is limited in several important respects. For example, no studies have examined the persistence or frequency of its use. None has systematically studied the factors associated with its use. Additionally, specific indications for which propoxyphene is still being prescribed have not been examined. Only two studies have assessed the risk of hip fractures with propoxyphene use; both used non-U.S. databases and have several limitations. This study aims to: (1) estimate the prevalence and persistence of propoxyphene use among community-dwelling aged; (2) determine the factors associated with propoxyphene use in the community-dwelling aged; and (3) establish whether propoxyphene use is associated with an increased risk of fractures in the aged. Data from the 1993-1999 Medicare Current Beneficiary Survey (MCBS) and the 1999 and 2000 MarketScan Datasets will be used. National-level annual prevalence estimates of propoxyphene use by community-dwelling aged Medicare beneficiaries will be made using 1993-1999 MCBS. A logistic regression will be estimated to identify specific patient, physician and drug plan characteristics associated with propoxyphene use. The MarketScan Dataset will be used to study proximate pain conditions for which propoxyphene is prescribed. A prospective cohort study design will be used with Cox regression analysis to estimate the increase in risk of fractures with propoxyphene use in the MarketScan Dataset. Determination of factors associated with propoxyphene use will help identify potential targets and design interventions to reduce its use. An establishment of an increased risk of fractures will strengthen the case for interventions to reduce propoxyphene use in the aged.

Hip Fracture
Summary: (Verbatim from the Applicant): In the clinical setting, areal bone mineral density (BMD) measurements by dual x-ray absorptiometry (DXA) estimate hip fracture risk by providing a surrogate measure for proximal femoral strength. Because DXA is a planar imaging modality, it has potentially important limitations. First, DXA quantifies integral bone mass and density, whereas the influence of the cortical and trabecular compartments on mechanical strength may exceed their contributions to the integral bone mass. Second, DXA BMD measurements scale with bone size; larger bones appear to be denser. The overall goal of our study is to understand how the projectional nature of DXA imaging affects its ability to depict proximal femoral strength in two populations with known differences in hip fracture rates, volumetric BMID, bone size and cortical thickness. To achieve this goal, we will carry out a study in vivo comparing proximal femoral strength, compartmental BMD and geometry in 400 elderly Caucasian and African-American women. To estimate femoral strength, we will image the subjects with volumetric quantitative computed tomography (vQCT) of the proximal femur and construct finite element (FE) models using the vQCT scans. We will calculate proximal femoral failure load (FL) by loading these models to failure with forces simulating a fall to the side with impact on the posterolateral aspect of the greater trochanter and a joint reaction force simulating a spontaneous fracture. In order to determine the relationship between DXA BMD and FL in these two race groups, we will acquire DXA hip scans in all of the subjects. To determine the relationship between FL, compartmental BMD and 3-D bone geometry, we will analyze the vQCT scans with a computer algorithm, which extracts measures of trabecular/cortical BMD and cross-sectional geometry. By determining the 3-D geometric and/or BMD factors which result in greater proximal femoral bone strength and understanding how these measures are modified by planar projection, we will gain considerable insight into the performance of DXA, the principal technique used to estimate proximal femoral strength and therefore, hip fracture risk.

Project Title: REDUCING BENZODIAZEPINES AND HIP FRACTURE IN THE ELDERLY Principal Investigator & Institution: Soumerai, Stephen B.; Ambulatory Care & Prevention; Harvard University (Medical School) Medical School Campus Boston, Ma 02115 Timing: Fiscal Year 2002; Project Start 01-MAY-2002; Project End 30-SEP-2004 Summary: (provided by applicant): Benzodiazepines (BZDs) are important, effective and widely used medications for treating anxiety, panic, sleep, seizure, and bipolar disorders. Epidemiological studies to date have produced conflicting data about hip fracture risk associated with BZD use by the elderly. This study provides a unique opportunity to compare an epidemiological assessment of the BZD-hip fracture relationship with results based on the effects of a statewide natural experiment that resulted in a sudden, sustained reduction in BZD use. The overall aim of this study is to determine whether BZDs are associated with increased hip fracture incidence in the elderly and, if so, which characteristics of BZD use are most likely to increase the risk. The proposed investigation will use a classical epidemiological design (Phase I) and a unique longitudinal, controlled, intervention-based (quasi-experimental) design (Phase II). The study populations will consist of elderly New York (NY) and New Jersey (NJ) Medicaid enrollees between October 1987 and December 1990. Phase I, an open cohort study of more than 50,000 elderly NJ Medicaid recipients, will estimate the magnitude and significance of the BZD-hip fracture association overall and in specific risk groups. Most importantly, Phase II will test whether a NY policy that dramatically reduced BZD

use also decreased hip fracture incidence (overall and in specific risk groups). On January 1, 1989, New York implemented a triplicate prescription program, a potent barrier to BZD prescribing, that resulted in a sudden, sustained decrease of over 50 percent in BZD use in most patient groups, including the elderly. The Phase II survival analyses of this natural experiment will compare changes in hip fracture incidence associated with the dramatic decline in BZD use in NY (intervention state) with changes in NJ (control state) where BZD use remained constant during the study period (total N=14,000). Medicaid and Medicare data provide reliable, valid, person-specific measures of demographics, medication and health services use over time, including hip fracture occurrence. The proposed study will provide important data on the association between BZDs, used by more than 20 percent of the elderly, and hip fractures, a major cause of morbidity and mortality. Phase II analyses will also contribute a novel method for evaluating health outcomes of changes in medication use in large populations.

Project Title: REHABILITATION AND FUNCTION RECOVERY AFTER HIP FRACTURE Principal Investigator & Institution: Young, Yuchi; Assistant Professor; Health Policy and Management; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2002; Project Start 15-MAY-1999; Project End 30-APR-2004 Summary: (adapted from Investigator's abstract) The broad, long-term objectives of this proposal are to understand the effects of post-acute rehabilitation and to improve functional independence among older hip fracture patients. The specific aims are: (1) To conduct an epidemiologic study of the pattern of use of post-acute rehabilitation facilities and the factors associated with choice of rehabilitation locations where patients receive their prescribed post-acute rehabilitation; (2) To examine the factors associated with the short-term and long-term effect of post-acute rehabilitation on functional recovery. The dose response effect of the amount of post acute rehabilitation on functional score will be tested adjusting for patient characteristics and other potential cofounders; (3) To examine the factors associated with Medicare payment incurred due to hip fracture in both the acute and post- acute care setting and to calculate the costeffectiveness ratio. Hip fracture, a major problem of persons ages 65 and over, causes significant mortality, morbidity, and functional impairment. The loss of functional independence imposes a heavy burden on individuals, caregivers, and requires costly long-term care. Rehabilitation, as a tertiary prevention, is intended to restore prefracture autonomy and functional independence. Previous studies have examined functional recovery among elderly hip fracture patients' who received interventions mostly in inpatient rehabilitation settings. Few studies have examined the effectiveness of post acute rehabilitation on functional outcome in multiple settings (inpatient, outpatient or subacute rehabilitation settings) and take into account the intensity and quantity of rehabilitation services received. The proposed study will use a longitudinal cohort design prospectively to collect and analyze demographic, medical, and psychosocial impacts of post acute rehabilitation on functional outcome and cost. Subjects will be a sample of 300 community- dwelling elders with unilateral hip fracture, who have had a surgical repair (internal fixation, hemiarthroplasty, or total hip replacement), and received prescribed post acute rehabilitations in any one of the predetermined inpatient, outpatient, or subacute rehabilitation facilities. The longitudinal data on demographic, medical, psychosocial characteristics and functional status will be collected through repeated interview surveys and Medicare claims data. The intent is that the results of this study will provide epidemiologic data on choice and utilization of post acute

rehabilitation settings, and information on the effectiveness of post acute rehabilitation on functional recovery and cost incurred. Findings will be useful for developing intervention programs to improve functional independence among elderly hip fracture patients.

Project Title: REHABILITATION FOR STROKE AND HIP FRACTURE Principal Investigator & Institution: Munin, Michael C.; Physical Medicine and Rehabilitation; University of Pittsburgh at Pittsburgh 350 Thackeray Hall Pittsburgh, Pa 15260 Timing: Fiscal Year 2002; Project Start 26-SEP-2002; Project End 31-AUG-2004 Summary: (provided by applicant): Hip fracture is one of the leading healthcare problems requiring rehabilitation services in older Americans. Three models of rehabilitation treatment are available for patients recovering from hip fracture that include acute inpatient rehabilitation (AR), nursing home rehabilitation (NHR) and home care rehabilitation (HCR). These settings differ based on the timing, duration and intensity of services provided. No prior randomized study has been performed to determine the optimum rehabilitation treatment to improve the rate of functional recovery and return home to the community for patients with hip fracture. This planning grant will complete work in the following key domains during the two-year grant cycle to perform a randomized controlled trial (1) coordinating facilities to assist subject recruitment using state of the art bioinformatics systems within the University of Pittsburgh Medical Center Health System; (2) performing focus interviews to better understand patient, family, physician and therapist values concerning the randomization process; (3) determining the best method to risk stratify patients to different treatment settings that include random assignment to a home rehabilitation arm; (4) refining physical and occupational therapy algorithms using similar treatment goals at each location; (5) incorporating outcomes that are validated, objective and reliable measures of self-reported function and observed physical performance; and (6) standardizing data measurements in all rehabilitation environments through the implementation of quality control procedures. Co-investigators from the RAND Corporation will refine methods for data analysis using their extensive expertise in outcome assessment. At the end of this two-year planning grant, the investigators expect to be well positioned to perform a randomized controlled trial. Primary hypotheses will test whether AR subjects have higher function and a lower percentage of extended care facility placements than patients receiving NHR or HCR. Using novel methodology developed by the research team, secondary hypotheses will evaluate the relationship of functional outcomes and intensity of therapy to level of participation in therapy and physical activity measured by an activity monitor.

Since femoral component subsidence measured on plain radiographs (accuracy 2-3

millimeters) is not typically evident before five years, lengthy follow-up is required to determine whether a new design reduces failure rates, and thereby widens patient indications and reduces complicated revision operations. Radiostereometry (RSA) sensitively (100-500 micrometers) tracks implant position. It is arguably the gold standard for detecting the early excessive subsidence shown to be a reliable predictor of ultimate clinical failure. However, implementation of RSA requires custom components and complex radiographic equipment, and is not widely available. We propose to develop an implantable, non-contacting sensing plug, to be inserted just distal to the tip of a femoral stem. External RF powering and embedded digital telemetry remotely query the plug to resolve subsidence to less than 100 micrometers, allowing the hallmark early subsidence (and thereby poor designs) to be detected within the first two years. Recoverable implant motion can be monitored real time (update rates of 200 Hz). The implanted microelectronics will include non-volatile memory and bi-directional wireless communications, allowing the plug to measure and maintain a record of subsidence over time.

Project Title: RISK FACTORS FOR HIP FRACTURES AMONG THE ELDERLY Principal Investigator & Institution: Melton, Joseph L.; Mayo Clinic Coll of Medicine, Rochester 200 1St St Sw Rochester, Mn 55905 Timing: Fiscal Year 2002 Summary: This project complements studies of pathophysiology by addressing fractures, the principle clinical manifestation of osteoporosis. Through the unique data resources of the Rochester Epidemiology Project, we can identify large inception cohorts of Rochester and/or Olmsted County, Minnesota., residents with specific medical and surgical conditions and conduct a series of retrospective (=historical) cohort studies to estimate the long-term risk of age-related fractures associated with secondary osteoporosis, an important contributor to bone loss in the elderly. Secondary, osteoporosis is an important area of research because new therapies are being developed for affected men and older women who are not candidates for estrogen replacement. We previously determined the risk of fracture among cohorts with diabetes mellitus, hyperparathryoidism, thyroidectomy, gastrectomy, pernicious anemia, oophorectomy, urolithiasis, anticoagulant therapy, anorexia nervosa, dementia, parkinsonism, epilepsy, poliomyelitis, rheumatoid arthritis, ankylosing spondylitis and breast cancer. We now proposed to extend this work by quantifying the fracture risk associated with conditions that might impair peak bone mass (endometriosis, infertility), induce hypogonadism (orchiectomy), disturb extraskeletal bone metabolism in the kidney (chronic renal failure) and gut (inflammatory bowel disease) or cause a generalized increase in bone resorbing cytokine (multiple myeloma). Each condition represents a natural experiment with respect to the pathogenesis of osteoporosis, several of which parallel the concerns of other projects. These will be the first assessments of fracture risk among cohorts of unselected patients from the community, and the results should be more valid and more precise than any previous estimates. Our overall goal is to develop new information that will lead to effective strategies for preventing osteoporosis-related fractures among the elderly. This project contributes by demonstrating the public health importance of specific risk factors and, by identifying high risk groups within each cohort, allowing future control programs to be designed and conducted more efficiently.

Project Title: STUDY OF OSTEOPOROTIC FRACTURES Principal Investigator & Institution: Ensrud, Kristine E.; Associate Professor; Epidemiology; University of Minnesota Twin Cities 200 Oak Street Se Minneapolis, Mn 554552070 Timing: Fiscal Year 2002; Project Start 01-FEB-1986; Project End 31-JUL-2006 Summary: (provided by applicant): The Study of Osteoporotic Fractures (SOF) is a multi-center longitudinal study in a cohort of 9,704 older women. SOF has comprehensive data about risk factors for osteoporosis and other diseases, along with an archive of serum, buffy coat and urine specimens. Data from SOF have served for: (1) developing osteoporosis guidelines, (2) estimating the cost-effectiveness of screening for osteoporosis, and (3) planning trials of osteoporosis therapies. They propose to renew SOF to sustain this unique resource and to pursue several new hypotheses. Osteoporosis is a chronic disease and prevention of fractures must be considered over the very longterm, not just the 3-5 year duration of most studies in the field. As the study of osteoporosis and aging with the longest (nearly 15 years) follow-up, SOF will provide the foundation for describing ways to identify people at greatest risk of osteoporosis and fractures decades in advance. They envision a new generation of clinical guidelines based on long-term prediction of risk of fractures and disability. Because they have enriched the cohort with African-American women, SOF will also provide unique information on risk factors for osteoporosis and non-spine fractures in older African American women. SOF was the first study to show a link between low BMD and risk of stroke and this has helped to fuel the interest and new investigations about the links between arterial calcification and osteoporosis. If they demonstrate, and can begin to explain, the link between these two diseases, this may lead to screening tools and treatments that simultaneously decrease the risk of both of these disabling conditions. Preliminary results from SOF suggest that impaired sleep may be a major cause of fractures, disability and decline in cognition in older women. If the next phase of SOF confirms these relationships using more objective measures of insomnia and other sleep disorders, then this might change current clinical policies and practices toward more aggressive screening and better coverage for treatment of sleep disorders. Finally, the value of SOF could be magnified by recruiting other scientists to work on SOF data and samples. They propose to make the database easily accessible to investigators outside of SOF and assist them in making productive use of a database that represents one of the most comprehensive prospective sources of information about the health of older women.

Project Title: TAMOXIFEN EFFECTIVENESS
&
BREAST
49
CANCER--ACCEPTANCE/COST
Principal Investigator & Institution: Melnikow, Joy A.; Family and Community Medicine; University of California Davis Sponsored Programs, 118 Everson Hall Davis, Ca 956165200 Timing: Fiscal Year 2002; Project Start 01-APR-2000; Project End 31-MAR-2004 Summary: Risk reduction or prophylaxis of breast cancer with tamoxifen is a controversial intervention. The decision to take or recommend tamoxifen presents a range of potential outcomes and associated costs which must be considered in both individual and clinical policy decisions. Objectives: The primary objectives of this 3 year proposal are: (1) to evaluate women's acceptance and utilities for the outcomes of tamoxifen prophylaxis of breast cancer, (2) to evaluate the association of self-perceived breast cancer risk with preferences for tamoxifen prophylaxis compared to the association of calculated breast cancer risk using the NCI Gail breast cancer risk screening tool with preferences for tamoxifen prophylaxis and (3) to determine the marginal cost- effectiveness of tamoxifen prophylaxis for reduction of breast cancer mortality compared with annual screening by clinical breast exam and mammography. Methods: We will collect cross- sectional data from interviews with 300 women as well as perform secondary analyses on pre-existing data. Utilities and patient preferences will be collected from interviews with 300 women potentially eligible for tamoxifen prophylaxis, as identified through use of the NCI Gail breast cancer risk screening tool. Because low income minority women have been largely excluded from clinical trials examining tamoxifen prophylaxis, particular efforts will be made to recruit African American and Latina women participating in California's Breast Cancer Early Detection Program for assessment of these parameters. Costs will be derived from Medicare average allowed charges and average wholesale prices for outpatient medications. Model probabilities will be determined when possible from a systematic review of the literature, relying primarily on recent published results from randomized trials and a large meta-analysis for relative risks of tamoxifen related outcomes, and population based data or large cohort studies for estimating baseline risks. When probabilities are not available from the medical literature, expert opinion will be solicited from a panel using a modified Delphi process. Outcomes will include breast cancer, endometrial cancer, venous thromboembolism, stroke, hip fracture, cataracts, and bothersome side effects. The cost-effectiveness analysis will be based on modifications of a previously developed Markov process model. One way and two way, sensitivity analyses and Monte Carlo analysis will be conducted. Expected results: Findings from this project will enhance understanding of women's decisionmaking about tamoxifen prophylaxis, identify key parameters influencing cost effectiveness of tamoxifen prophylaxis, and provide perspective on the marginal cost effectiveness of tamoxifen compared with other preventive interventions, outside the context of randomized controlled trials.

Hip Fracture
therapy in subacute rehabilitation. Two distinct approaches to therapy are routinely practiced: (a) a functional approach involving participation in daily living tasks; and (b) a rote exercise approach whereby the patient is instructed to follow exercise protocols. In the proposed project, these two approaches will be compared in subacute rehabilitation patients with hip fracture. Subacute rehabilitation is a neglected site for research, even though it is one of the most common settings for therapy practice. Hip fracture, frequently occurring in frail elderly persons with multiple health problems, is one of the most important diagnoses in this setting. The two specific aims are to determine if there is a difference between the functional approach to rehabilitation and the rote exercise approach to rehabilitation in terms of improvement in (a) the motor abilities required for daily living tasks, and (b) self-reported physical health status. The design is a randomized trial (pretest-posttest design) with blind assessment of outcomes. The final sample size of 104 provides adequate power. The two dependent variables are derived from the Assessment of Motor and Process Skills and the SF-36. Protocols for the two interventions include specifications for each intervention as well as lists of daily living tasks or exercises appropriate to each intervention. Pre-training and ongoing training of interventionists emphasizes equivalent attention and balance across conditions while preventing inadvertent contamination across conditions. Intervention fidelity will be tested by an independent, blind reviewer of clinical notes. Each specific aim will be tested by analysis of covariance, with the pretest as a covariate and with other relevant covariates including co-morbidities, cognitive status, hours of therapy, age, and gender. Alpha will be set at.05 for a two-tailed test. The proposed project follows logically from a smaller project funded by the American Occupational Therapy Foundation, and leads logically to a multi-site clinical trial of these two commonly used but untested approaches to rehabilitation.

Project Title: TESTING THE EXERCISE PLUS PROGRAM FOLLOWING HIP FRACTURE Principal Investigator & Institution: Resnick, Barbara M.; None; University of Maryland Balt Prof School Baltimore, Md 21201 Timing: Fiscal Year 2002; Project Start 30-SEP-1999; Project End 30-JUN-2005 Summary: (Adapted from Investigator's Abstract) Hip fracture is a major public health problem. More than 50% of patients do not return to pre-fracture functional levels one year post fracture. Recovery following hip fracture has been shown to be greatly improved by rehabilitation services and exercise. In older adults, regular exercise prevents disease, decreases the risk of falling, reduces disability, improves sleep, and enhances mood and general well-being. Specifically for older adults post hip fracture, exercise can improve mobility (speed and weight-bearing ability), strength, functional performance, and prevent future falls. Unfortunately, the majority of older adults do not exercise regularly, and approximately 50% of those who begin exercise programs drop out by six months. The major aim of this study is to test the effectiveness of a home delivered self-efficacy based intervention, the Exercise Plus Program, on increasing exercise behavior in older adults post hip fracture. Participants will be randomly assigned to one of the four groups defined by the 2 X 2 design: (1) Exercise Trainer component which includes regular home visits by an exercise trainer to implement an exercise program with patients; (2) Plus Component only which includes motivational interventions but without an exercise trainer to exercise with; (3) the full Exercise Plus program which includes the Plus Component (motivational interventions) and the Exercise Trainer component; or (4) routine care. Five acute care facilities participating in
Studies
51
the Baltimore Hip Studies will be used to recruit participants. A total of 240 (60 per group) older adults will be included in the study. Baseline testing will be done in the acute care setting, and the intervention implemented in the home setting when traditional inpatient rehabilitation services are completed. Efficacy expectations related to exercise, exercise behavior, activity, functional performance, health status, pain, mood, fear of falling, falls, and injuries related to falls will be measured at baseline, and then at two, six, and twelve months post hip fracture. The primary outcomes will be efficacy expectations, exercise behavior, and activity; secondary outcomes will focus on the benefits of exercise (such as improved function). Generalized estimating equations will be used to perform the analyses with both binary and continuous outcome measures as dependent variables. The investigators state that this study will contribute to the understanding of what interventions improve exercise behavior in the older adult post hip fracture, and add to the current base of knowledge regarding the benefits of exercise in frail older persons.

Project Title: TESTOSTERONE FOR PREVENTION OF FRACTURE IN MEN Principal Investigator & Institution: Kenny, Anne M.; Assistant Professor; Medicine; University of Connecticut Sch of Med/Dnt Bb20, Mc 2806 Farmington, Ct 060302806 Timing: Fiscal Year 2002; Project Start 30-SEP-2001; Project End 30-JUN-2006 Summary: (verbatim from application) Attention to osteoporosis has largely emphasized women's health, and little attention has focused on the diagnosis and prevention of osteoporotic fractures in men. And yet the disease is also an important problem in men. Tesosterone levels decline with advancing age, and severe testosterone deficiency is associated with low bone mass and fracture. Several epidemiologic studies suggest that low testosterone is associated with low bone mass in older men, but this finding is not consistent. Men with hip fracture are found to be testosterone deficient more often than control subjects. Among men over age 70 with testosterone levels below young normal range, we found differences in bioavailable testosterone accounted for 20 percent of the variance in femoral next bone mineral density (FN BMD) values. Based on these data, testosterone supplementation may be important for bone health in older men. We will test the hypothesis that testosterone supplementation can decrease the risk of subsequent vertebral and non-vertebral fractures in older men with recent hip fracture. We will also evaluate the effects of testosterone on general health and wellbeing in this group. The specific aims of the proposed study will be to determine the effect of testosterone supplementation on vertebral and non-vertebral fractures incidence in men, age 60 years and older, who have sustained a recent hip fracture. Two hundred men, age 60 years and older, who have sustained a hip fracture following mild to moderate trauma (such as a fall from a standing height in the previous 2-6 months) will be randomly assigned to receive either long-acting testosterone or placebo injections in a double-blind study. We will ascertain new, non vertebral fracture incidence by structured questionnaire and follow-up radiographic confirmation every 6 months for 36 months, as well as vertebral fracture rates with baseline lateral spine films and yearly follow-up lateral spine films. In addition, bone mineral density (BMD) of the proximal femur, lumbar spine, distal radius and total body by dual x-ray absorptiometry (DXA) will be performed at baseline and yearly for 3 years to assess changes in BMD. In addition, we will determine the effect of testosterone on general health, including physical and cognitive function, cardiovascular risk, body composition and prostate parameters. Various physical and cognitive measures will be assessed, cardiovascular risk will be assessed by lipid profile and body composition from the whole body DXA

and prostate parameters will include prostate specific antigen levels, American Urologic Association Prostate Symptom Score and digital rectal examination of the prostate. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: TESTOSTERONE THERAPY AFTER HIP FRACTURE IN ELDERLY WOMEN Principal Investigator & Institution: Binder, Ellen F.; Associate Professor; Internal Medicine; Washington University Lindell and Skinker Blvd St. Louis, Mo 63130 Timing: Fiscal Year 2004; Project Start 01-JUN-2004; Project End 31-MAY-2006 Summary: provided by applicant): Hip fractures are common among elderly women and can have a devastating impact on their ability to remain independent. A significant functional decline following a hip fracture has been documented, and many patients have persistent strength and mobility deficits that impair their capacity for independent function. Such individuals are at high risk for continued supportive services, recurrent injury, and institutionalization. High-risk patients include those with deficits in skeletal muscle strength during the post fracture period. Age-associated androgen deficiency contributes to deficits in muscle mass and strength that are common in this patient population. The role of testosterone therapy for improving deficits in muscle mass, strength, and functional capacity in the frail elderly is unclear, particularly for elderly women. There is insufficient information regarding tolerability of testosterone therapy, and the appropriate medication dosage and target serum testosterone levels necessary to induces changes in skeletal muscle mass and functional measures in elderly women with physical frailty due to muscle weakness. The goals of this project are to conduct a randomized, double-blinded, placebo-controlled prospective study to determine the feasibility, tolerability, and safety of 6 months of testosterone therapy in community dwelling, physically frail, elderly female hip fracture patients. Twenty-seven female hip fracture patients will be enrolled, using objective criteria for testosterone deficiency and frailty. We plan to evaluate two dosages of testosterone, administered as a 0.5% topical gel: a physiologic replacement dosage, and a supraphysiologic dosage. We plan to carefully monitor testosterone levels, side effects, biochemical parameters, and factors related to compliance with therapy. We plan to obtain preliminary information regarding the changes in measurements of muscle strength, total score on an Objective Physical Performance Test, total lean body mass by dual energy x-ray absorptiometry (DEXA), thigh cross-sectional areas by magnetic resonance imaging (MRI), and selfreported performance of activities of daily living, and quality of life. These data will be used to develop a full-scale proposal to test the long-term hypothesis that testosterone therapy combined with exercise training can improve physical function after a hip fracture.

Project Title: THE 3 COHORT STUDY OF HIP FRACTURE FUNCTIONAL OUTCOMES Principal Investigator & Institution: Siu, Albert L.; Professor; Medicine; Mount Sinai School of Medicine of Nyu of New York University New York, Ny 10029 Timing: Fiscal Year 2003; Project Start 30-SEP-2003; Project End 31-AUG-2006 Summary: (provided by applicant): Hip fractures are an important cause of mortality and functional dependence among older adults and approximately 340,000 hip fractures occur annually in this country. The proposed project brings together 3 cohorts of 2819 patients with hip fracture to create the largest dataset of hip fracture patients with

53
follow-up information on functional outcomes. This dataset will be used to address 2 important topics in hip fracture research: a) the characterization of patient subgroups that could be targeted for future clinical interventions, and b) the role of early surgical intervention. The specific aims are: a) to combine the Mount Sinai, Baltimore, and Hospital for Joint Disease hip fracture cohorts to produce a dataset with information on patient characteristics, pre-fracture function, process of inpatient care, and longitudinal follow-up on function and other outcomes; b) to better characterize the mortality and functional outcomes of subgroups of hip fracture patients; c) to test how pre-fracture function, patient characteristics, and co-morbid conditions affect functional outcomes for patients as a whole and for major subgroups; and d) to test the impact of early surgery for patients with hip fracture. Our research methods include: a) assembling the dataset and creating and testing common definitions of study variables from the 3 cohorts; b) using cluster analysis to identify clinically important subgroups and to examine differences in mortality and functional outcomes among the subgroups; and c) analyzing the determinants of mortality and functional outcome, including the effect of early surgery. In the course of doing this, we will extend the methodological work on a) how mortality can be incorporated into analyses of functional outcome and b) how observational data can be analyzed to assess the effectiveness of interventions that are not likely to be evaluated in randomized trials. These 2 latter topics are critical issues to a series of other clinical topics in aging. The methodologies we propose to develop and test has wide applicability to other clinical problems of aging where functional status is an important outcome and mortality is also high.

Project Title: THE CAUSES OF HEALTH CARE INTENSITY Principal Investigator & Institution: Skinner, Jonathan S.; Professor; Dartmouth College 11 Rope Ferry Rd. #6210 Hanover, Nh 03755 Timing: Fiscal Year 2002 Summary: (provided by applicant): Wide variations in Medicare spending per capita are observed across geographic regions. In 1996, age, sex and race adjusted spending for traditional (fee-for-service) Medicare in the Miami region was $7,783, compared to the $3,700 spent in the Minneapolis region. Little is known about the causes of such differences; are they the consequence of patient preferences, market structure, physician beliefs, the availability of health care resources, or some combination of all factors? To better understand the dimensions and implications of health care intensity, we intend to: 1. Characterize health care intensity at the level of regions or hospitals using the clinically rich data available from population-based Medicare administrative files. We will develop models that allow us to examine dynamic associations among components of health care intensity, particularly for patient suffering from chronic disease and near the end of life. 2. Determine whether preferences of patients are aligned with the intensity and mix of care that they get. We test this hypothesis by comparing the stated preferences of patients in the telephone survey with the intensity and nature of care that they receive. We will consider whether education, race, or other factors makes it more likely that patients get what they say they want. 3. Study the role of patient preferences, physician beliefs, and the structure of the health care market in explaining differences in intensity across regions or hospitals. We seek to explain why Miami spends twice as much in Medicare expenditures as Minneapolis; is it because patients want the extra care, because of a larger share of for-profit hospitals, the importance of managed care in Minneapolis, or physician beliefs about appropriate treatment? 4.

preferences evolve over time. Do patient preferences gradually evolve towards the characteristics of the region in which people receive their care? Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: THE CONSEQUENCES OF HEALTH CARE INTENSITY Principal Investigator & Institution: Fisher, Elliott S.; Professor of Medicine; Dartmouth College 11 Rope Ferry Rd. #6210 Hanover, Nh 03755 Timing: Fiscal Year 2002 Summary: (provided by applicant): There appear to be differences in the way that medicine is provided across region. This project addresses the consequences of regional differences in health care intensity for health, functioning, and well-being more generally. Knowing the answer to these questions is important, because it will allow us to judge whether elderly Americans in high expenditure regions value the additional care they are receiving. In particular, the goals of this project are to 1. Study the impact of variations in health care intensity on survival by carrying out longitudinal cohort studies of three chronic disease cohorts, i.e., myocardial infarction, hip fracture and colon cancer. 2. Examine the impact of variations in intensity on function, well-being and disease-specific quality of life using longitudinal cohort studies in three groups sampled from the Medicare population: the Medicare Current Beneficiary Survey (MCBS), for whom we have measures of self-assessed health and physical function, the proposed Core Survey, for whom we have measures of well-being in physical wellbeing and mental well being, and men in regions that were early and later adopters of a more intensive approach to the detection and treatment of prostate cancer. 3. Explore how intensity is valued in different regions. We will use data from the Core Telephone Survey to determine patient preferences for specific treatments and determine the degree to which high or low intensity regions improve the health and functioning of patients with different preferences. We will use in-person interviews in three regions (Florida, Oregon, and Sun City, Arizona) to determine how Medicare enrollees in these communities value major dimensions of intensity and whether those values reflect community treatment patterns.

Project Title: TIMING AND INTENSITY OF STRENGTHENING AFTER HIP FRACTURE Principal Investigator & Institution: Craik, Rebecca L.; Professor and Chair; Physical Therapy; Arcadia University 450 S Easton Rd Glenside, Pa 19038 Timing: Fiscal Year 2002; Project Start 26-SEP-2002; Project End 31-AUG-2004 Summary: (provided by applicant): Despite dramatic improvements in medical management of hip fracture, we have been unsuccessful in reducing the significant residual disability that remains in older persons post-fracture. The burgeoning economic cost of this seemingly simple condition and the burden of care borne by caregivers and society are predicted to escalate. Systematic investigations of promising interventions are needed. The interventions should be specific to the deficits that impede recovery, i.e., muscle mass and strength, should be of the correct intensity and be introduced at the most appropriate time to achieve the most beneficial outcome. This planning grant will be used to refine a future trial, a home-based exercise program. The investigators propose to evaluate the intensity and timing of an exercise program to reduce the level of disability post-hip fracture. This planning effort will be used to design a randomized controlled trial (RCT) to compare two different intensities of lower extremity exercise

delivered at different times post-fracture to a sham, attention control group. In this future trial the investigators plan to include a broader range of patients with hip fracture than has been included in previous studies instead of focusing only on individuals with the best chance for recovery. They also will document aspects of current rehabilitation care, and identify the factors that predict success of this intervention. The planning project brings together a dynamic group of investigators expert in studying hip fracture outcomes and clinical methodologies. The investigative team consists of experts in hip fracture outcomes, clinical methodologies, and physical intervention required to design and lead a randomized controlled trial of an exercise program following hip fracture. Specific aims of the present application for a planning and development grant are to (1) refine the study design of the future trial; (2) prepare detailed protocols for successful enrollment of subjects in the future trial; (3) establish reliable procedures to ensure treatment adherence; (4) prepare detailed protocols to enable meaningful outcome assessment in the future trial; and (5) develop the future trial budget.

Project Title: TROCHANTERIC PADDING TO PREVENT HIP FRACTURES Principal Investigator & Institution: Kiel, Douglas P.; Associate Professor; Hebrew Rehabilitation Center for Aged 1200 Centre St, Roslindale Boston, Ma 02131 Timing: Fiscal Year 2002; Project Start 30-SEP-2001; Project End 31-AUG-2006 Summary: (provided by applicant) As measured by their frequency, influence on quality of life and economic cost, hip fractures are a public health problem of crisis proportions. Studies suggest that hip fractures may be prevented by the use of protective trochanteric padding, although some of those studies were small, had potential biases introduced by randomizing nursing homes or nursing home units, and used energy shunting pads. Fractures may still occur beneath such pads, and compliance has been variable because these pads were not particularly easy to wear or comfortable. We plan to conduct a randomized controlled trial of an energy absorbing and distributing, trochanteric padding system to reduce the incidence of hip fractures in 546 NH residents followed for an average of three years. To carry out this trial, a Coordinating Center (Maryland Medical Research Institute in Baltimore) will work with three clinical centers in Boston, Baltimore, and St. Louis that will each recruit 10-14 NHs and 182 NH residents to participate; residents will be replaced as they drop out during the follow up period. This sample size accounts for an effect size of 50 percent, and compliance rate of 50 percent. Each subject will be given a set of protective underwear containing a single pocket and hip pad so that each resident becomes his/her own control. The side to be protected is based on the randomization of facilities to be either "right" or "left-sided" such that the final sample will consist of an approximately equal number of residents with protection on the right as on the left hip. Using an intent to treat analysis, we will compare hip fracture incidence in padded and unpadded hips. The secondary aim will be to identify patient and facility factors contributing to non-adherence with the use of hip protectors. This will be the largest clinical trial of this biomechanically tested, energy absorbing and distributing hip protector ever conducted in the United States.

Project Title: VITAMIN D SUPPLEMENTATION IN POSTMENOPAUSAL WOMEN Principal Investigator & Institution: Aloia, John F.; Winthrop-University Hospital 259 1St St Mineola, Ny 11501
56
Hip Fracture
Timing: Fiscal Year 2002; Project Start 15-SEP-1998; Project End 31-JUL-2004 Summary: (Adapted from the Applicant's Abstract): The long-term goal of this project is to develop strategies for the prevention of osteoporotic fractures in black women. Most studies have excluded black women because of the mistaken belief that osteoporosis is not a major health problem in this population. It is true that black women have a higher bone density, protective anatomic geometry of the femur, and a larger muscle mass compared to white women. Nonetheless, the incidence of hip fracture in black women is as great as 40% of that in white women. As the black population ages, osteoporosis will become even a greater health problem for this ethnic minority. Black women have lower levels of calcidiol and higher levels of parathyroid hormone (PTH) than white women. Since black women have lower indices of bone turnover, they also appear to have a relative resistance to the effect of PTH. Dietary supplementation with vitamin D3 has been shown to safely reduce bone loss and prevent hip fractures in postmenopausal white women. The strategy of vitamin D3 supplementation to prevent osteoporosis is even more cogent in black postmenopausal women compared to white women because (a) they have lower calcidiol levels, (b) they have evidence of secondary hyperparathyroidism, (c) the long-term effects and risks of hormonal replacement therapy have not been evaluated in black women, and (d) because of their higher bone mass, low risk strategies are more appropriate. There are less black women with osteoporosis at menopause, so that a modest reduction in bone loss could have a great impact on prevention of osteoporosis. The specific aim of this project is to determine if daily dietary supplementation with 800 IU (20 ug) of vitamin D3 will reduce bone loss in postmenopausal black women. A secondary aim is to evaluate the changes in the vitamin D-endocrine system and indices of bone turnover that result from long term vitamin D3 augmentation. A positive response would provide a safe, inexpensive and acceptable strategy for prevention of osteoporotic fractures in black women. If this randomized clinical trial demonstrates a positive effect on prevention of bone loss, a large scale multi-centered trial with fracture prevention as an endpoint will have merit.

Project Title: WHI SEX HORMONE & GENETIC RISK FACTORS FOR HIP FRACTURE Principal Investigator & Institution: Cummings, Steven R.; California Pacific Med CtrPacific Camp 2200 Webster Street, Suite 514 San Francisco, Ca 94115 Timing: Fiscal Year 2003; Project Start 24-SEP-2003; Project End 31-MAR-2006 Summary: (provided by applicant): In the United States, many hip fractures occur each year, causing significant disability and premature deaths. Cases of hip fractures cost an estimated $7 billion annually. Several etiologic factors are implicated in fracture risk including hormonal, metabolic, and genetic contributions. We propose to examine promising hormonal and genetic markers for hip fracture risk; this is a major objective of the Women's Health Initiative Observation Study (WHI-OS), a prospective study of over 93,000 postmenopausal women. Among WHI-OS participants, we will investigate whether low levels (especially very low levels) of estradiol, high levels of steroid hormone binding globulin, and low levels of insulin like growth factor 1 increase the risk of hip fracture. Recent studies also have identified promising polymorphisms in several candidate genes related to bone metabolism that may substantially affect hip fracture risk. We will test whether candidate polymorphisms in the following genes contribute to hip fracture risk: APOE, estrogen receptor alpha-l, transforming growth factor-beta and collagen type 1 alpha 1, and LDL receptor-related protein 5. Recent data support the functional role of these polymorphisms in the maintenance of bone mass
Studies
57
and metabolism, suggesting that they may contribute to osteoporotic fracture risk. Identifying such hormonal and genetic markers for increased fracture risk ultimately may provide insight into treatment methods, at risk populations that could benefit from preventive measures, and new hypotheses about the pathophysiologic mechanisms for increased fracture risk. Among eligible WHI-OS participants aged 55-79 years at baseline, we will use a nested case-control study design to identify 400 cases of first hip fracture and 400 age-, ethnicity-, and center-matched controls for this study. This study will use previously collected baseline data and stored specimens in WHI-OS, including existing baseline serum and buffy coat samples and documentation/adjudication of hip fracture events. WHl data include comprehensive measurements of potential confounders and effect modifiers that will be considered in the analyses. The proposed study is a very efficient approach to understanding the etiologies of hip fracture. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

CHAPTER 2. NUTRITION AND HIP FRACTURE Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and hip fracture.
Finding Nutrition Studies on Hip Fracture 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.7 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 “hip fracture” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.
7 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 3. ALTERNATIVE MEDICINE AND HIP FRACTURE Overview In this chapter, we will begin by introducing you to official information sources on complementary and alternative medicine (CAM) relating to hip fracture. At the conclusion of this chapter, we will provide additional sources.
National Center for Complementary and Alternative Medicine The National Center for Complementary and Alternative Medicine (NCCAM) of the National Institutes of Health (http://nccam.nih.gov/) has created a link to the National Library of Medicine’s databases to facilitate research for articles that specifically relate to hip fracture and complementary medicine. To search the database, go to the following Web site: http://www.nlm.nih.gov/nccam/camonpubmed.html. Select “CAM on PubMed.” Enter “hip fracture” (or synonyms) into the search box. Click “Go.” The following references provide information on particular aspects of complementary and alternative medicine that are related to hip fracture: •

CHAPTER 4. DISSERTATIONS ON HIP FRACTURE Overview In this chapter, we will give you a bibliography on recent dissertations relating to hip fracture. We will also provide you with information on how to use the Internet to stay current on dissertations. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical dissertations that use the generic term “hip fracture” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on hip fracture, we have not necessarily excluded non-medical dissertations in this bibliography.
Dissertations on Hip Fracture ProQuest Digital Dissertations, the largest archive of academic dissertations available, is located at the following Web address: http://wwwlib.umi.com/dissertations. From this archive, we have compiled the following list covering dissertations devoted to hip fracture. You will see that the information provided includes the dissertation’s title, its author, and the institution with which the author is associated. The following covers recent dissertations found when using this search procedure: •

CHAPTER 5. PATENTS ON HIP FRACTURE 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.8 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 “hip fracture” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on hip fracture, we have not necessarily excluded non-medical patents in this bibliography.
Patents on Hip Fracture By performing a patent search focusing on hip fracture, 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. The following is an 8Adapted

example of the type of information that you can expect to obtain from a patent search on hip fracture: •
Enhancement of return to independent living status with a growth hormone secretagogue Inventor(s): Bach; Mark (Scotch Plains, NJ), Fuh; Vivian (New York, NY), Ng; Jennifer (Short Hills, NJ), Taylor; Alice (Edison, NJ) Assignee(s): Merck & Co., Inc. (Rahway, NJ) Patent Number: 6,194,402 Date filed: August 31, 1999 Abstract: A growth hormone secretagogue is useful for enhancing the return of patients to independent living status following acute deconditioning such as that which may result from immobilization, surgery, or major injury such as hip fracture. Excerpt(s): Many patients who receive surgery or experience a major illness or injury require additional care and supervision following such surgery or illness. Patients who receive surgery or experience a major illness or injury such as hip fracture may have prolonged recovery times due to deconditioning, a bed-rest associated syndrome comprising, e.g.: decreased cardiac output, hypotension, muscular atrophy and acute muscle loss, and joint contractures (Hoenig and Rubenstein, Journal of the American Geriatrics Society, 39, 220-221. (1991)). In the elderly the loss of muscle mass and function as a result of illness or immobilization may be up to 5% per day at bedrest. Among the elderly in particular, deconditioning associated with acute illness is believed to lead to recovery times far in excess of that expected for the acute illness itself. In addition to prolonged recovery times, functional losses may result from deconditioning, the acute illness itself, and untoward effects of treatment. Although many functional losses are often reversible with activity and exercise interventions, recovery times may vary widely (Vorhies and Riley, Clinical Geriatric Medicine, 9, 745-763 (1993)). There are direct and indirect costs associated with both the acute illness and recovery periods. These costs may be considerable. As a result of their deconditioned physical state, patients who had once been able to live independently may require additional assistance and care. In particular, patients who had previously lived independently in a private home or apartment may find that following surgery or a major illness or injury they require the formal care provided by an assisted living center, a nursing home, a rehabilitation hospital/center, an acute care hospital or a chronic medical care center. This increase in the degree of care which is required by an individual following such deconditioning imposes increased financial costs. Moreover, such restrictions in their lifestyle may impose detrimental psychological impact with respect to the patient's self esteem and independence.

Intramedullary rod for fracture fixation of femoral shaft independent of ipsilateral femoral neck fracture fixation Inventor(s): Latour, Jr.; Robert A. (Clemson, SC), Shuler; Thomas E. (Pittsburgh, PA) Assignee(s): Clemson University (Clemson, SC), Greenville Hospital System (Greenville, SC) Patent Number: 5,429,640 Date filed: November 27, 1992 Abstract: A femoral intramedullary rod has a thin or reduced proximal segment so as to provide room for the use of femoral hip screws. Use of the rod for femoral shaft fixation permits subsequent independent treatment of an ipsilateral femoral hip fracture as an isolated injury, regardless of whether initially detected. Different rod embodiments are formed by the omission of different proximal portions of the rod. It is in such portions that the femoral screws may be placed to set hip fractures. The rod is cannulated for installation over a guide wire. Internal rod threads, below the thin proximal segment in some embodiments, are used for initial installation of the rod with a driving member screwed into such threads. Without driving forces on the thin proximal segment, such segment can be made even thinner. Once the rod is seated, hip screws may be installed if there is a detected hip fracture. Subsequent to healing, the femoral screws and interlocking screws (if any) may be removed. A hollow reamer sized for clearance over the intramedullary rod may be placed down over the top of the rod to cut away any bony tissue ingrown into the proximal end. Thereafter, the rod is extracted with a suitable extraction device. Excerpt(s): The present invention relates in general to improved treatment for fractures of the femur and in particular concerns apparatus and methodology for the efficacious treatment of the highly problematic combination of a femoral shaft fracture with an ipsilateral femoral neck fracture (i.e., femoral hip region fracture). The femur or thigh bone is the largest and longest bone in the human skeleton. In general, it comprises two extremities connected by an elongated fairly cylindrical shaft. The upper or proximal extremity may be broadly regarded as constituting the hip region. Generally speaking, fracture injuries to the femoral shaft have been primarily treated (per current acceptable methods) with various intramedullary rods or nails. An intramedullary rod is an elongated member which is introduced to and resides in the marrow of the femur for the purpose of stabilizing the fractured femoral shaft. It is desired that stabilization take place in conjunction with anatomic reduction (i.e., proper reorientation of fractured elements to their original position, both relative to one another and relative to other adjacent anatomical features). As well known to those of ordinary skill in the art, installation of intramedullary rods often involves passage through the upper extremity or hip region, and in fact results in the proximal end of the rod occupying a significant portion of the hip portion of the femur.

Mouse growth hormone secretagogue receptor Inventor(s): Howard; Andrew D. (Park Ridge, NJ), Jiang; Michael M. (Edison, NJ), McKee; Karen Kulju (Middletown, NJ), Smith; Roy G. (Houston, TX), Van der Ploeg; Leonardus H. T. (Scotch Plains, NJ), Zheng; Hui (Houston, TX) Assignee(s): Merck & Co., Inc. (Rahway, NJ) Patent Number: 6,682,908 Date filed: June 13, 2001 Abstract: A mouse growth hormone secretagogue receptor has been isolated, cloned and sequenced. This receptor is characteristic of the G-protein family of receptors. Mouse growth hormone secretagogue receptors may be used to screen and identify compoumds which bind to the mouse growth hormone secretagogue receptor. Such compounds may be used in the treatment of conditions which occur when there is a shortage of growth hormone, such as observed in growth hormone deficient children, elderly patients with musculoskeletal impairment and those recovering from hip fracture and osteoporosis. Targeted disruption of the mouse GHS-R gene may prove useful in elucidation of the mechanism of action and role of the growth hormone secretagogues in human and animal physiology. Excerpt(s): This invention relates to a newly identified receptor, the mouse growth hormone secretagogue receptor (mGHS-R), nucleic acids encoding this receptor; and to the use of a mGHS-R to identify growth hormone secretagogues and compounds that modulate mGHS-R function. Growth hormone secretagogues (GHSs) and secretagoguelike compounds, both peptide and non-peptide, bind to and exert their biological effects (i.e., release of growth hormone (GH)) through a G protein-coupled receptor (GPC-R) distinct from the receptors for growth hormone releasing hormone (GHRH) and somatostatin (SST) (Pong et al., 1996 Mol. Endocrin. 10:57-61). The molecular cloning of this growth hormone secretagogue receptor (GHS-R) capitalized on the pivotal observation that GHSs transduce their signal through activation of the phospholipase C pathway (Cheng et al., 1991 Endocrinology 129:3337-3342; Howard et al., 1996 Science 273:974-977). cDNA and genomic DNA cloning from human, swine, and rat showed that the GHS-R is a protein of 364/366 amino acids containing 7 putative alpha-helical transmembrane (TM) domains, a signature feature of GPC-Rs (Howard et al. 1996; McKee et al., 1997 Mol. Endocrin. 11:415-423). In all species evaluated, the GHS-R is encoded by a single highly-conserved gene containing one intron, placed at the Cterminal end of TM domain 5. The biology of the growth hormone secretagogues (GHSs) is still in a relatively early stage of development. Research is focused on identification of the GHS natural ligand system and understanding the role of the GHSR in brain regions (substantia nigra, dentate gyrus, hippocampus) other than those traditionally thought to be involved in GH secretion (Bennett et al. 1997; Guan et al. 1997).

Protector pad Inventor(s): Kummer; Frederick J. (Brooklyn, NY) Assignee(s): Hospital for Joint Diseases (New York, NY) Patent Number: 5,062,433 Date filed: January 16, 1990 Abstract: A protector to prevent hip fracture and/or bed-sores and/or protect a wound or wound area is formed from an outer load bearing member reinforced by internal ridges. The protector is dome shaped with structured ridges to form an internal dome or clearance for the region of desired protection. A soft inner sheet is attached for comfort. This structure has less bulk and weight than a solid pad. The outer shell formation distributes the load or pressure to the edges of the device, protecting the organ covered by the dome. The pad may have different internal ridge patterns to provide flexibility for user comfort. Excerpt(s): The present invention relates to pads or padded bandages particularly useful in covering and/or protecting the body from injury and/or covering and/or protecting an injury or wound on-the body. In particular the present invention is a light-in-weight and reduced-in-bulk pad useful particularly in the upper leg and hip area for preventing injury to the hip. It can also prevent sores from occurring and be used for protecting the upper leg and hip region where the individual using the padded bandage has been subjected to surgery on the hip or some wound in the upper leg and/or hip region. There are, in the United States alone, approximately 150,000 to 200,000 hip fractures each year. Many of the hip fractures require surgical procedures to properly align the fractured bone so as to promote proper healing. Surgery, especially hip surgery, normally results in a wound on the outside of the hip region, which is more often difficult to protect, especially when the patient becomes ambulatory. Protective pads have been designed to protect hip surgical wounds and other hip wound areas. Some of these are large domelike pads formed by a large, rigid outer shell. The size of the wound and/or wound area dictates the size of the protective pad to be used and as the size of the wound and/or wound area increases both the bulk and weight of the protective pad increase. The overall bulk of this type of hip region protective pad is objectionable, to the user of such pad, especially since the rigid shell forming it is not flexible.

Hip Fracture
Patent Applications on Hip Fracture As of December 2000, U.S. patent applications are open to public viewing.9 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 hip fracture: •
Enhanced graphic features for computer assisted surgery system Inventor(s): Kienzle, Thomas C. III; (Lake Forest, IL) Correspondence: Bullwinkel Partners, LTD.; 19 South Lasalle ST.; Suite 1300; Chicago; IL; 60603; US Patent Application Number: 20020077540 Date filed: November 19, 2001 Abstract: A computer assisted surgery system with is enhanced graphics features is described for assisting a surgeon in orthopaedic procedures. A system is described for use in inserting multiple guide pins in hip fracture surgery using a single bore drill guide that has a graphical representation comprising its real trajectory and one or more virtual trajectories, the virtual trajectories representing potential positions of other guide pins to be placed during the procedure. Additionally, representations of inserted guide pins and virtual trajectories may be retained on the display at their inserted positions for use in aligning subsequent guide pins. A system is also described for orientation of an acetabular cup in a total hip replacement surgery. During cup insertion, the surgeon is provided with information regarding the orientation of the cup with respect to a pelvic reference frame that is based on accepted pelvic landmarks. The positions of each landmark is calculated by the system when a probe with a virtual tip, separate from its physical tip, is overlaid on the landmark in roughly orthogonal images of the pelvis. Excerpt(s): This invention relates to a computer assisted surgery system with enhanced graphics capabilities for use in inserting multiple screws into a hip fracture and orienting a total hip acetabular component. Fractures of the femoral neck, one kind of hip fracture, are a common injury of the elderly with over 150,000 such fractures occurring annually. The currently accepted treatment for mildly displaced femoral neck fractures is surgical fixation. In the procedure, three cannulated screws are inserted in the hip, from the lateral aspect of the femur, across the fracture site and into the femoral head. The initial step is the placement of three guide pins, over which the screws are inserted, in a characteristic triangular pattern. This is typically performed under fluoroscopic guidance, usually with the aid of a drill guide. Some surgeons prefer to use a drill guide with a single bore, but doing so may make it difficult to achieve the desired triangular spacing and optimum placement of the guide pins in the femoral neck. Other surgeons prefer a drill guide with multiple bores that are fixed in the proper triangular spacing, but this requires a larger incision and doesn't permit the surgeon much flexibility to modify the preset pattern. With either drill guide, it can be difficult to accurately predict the final guide pin placement. Further, the surgery requires a significant number of fluoroscopic images and x-ray exposure for the surgeon, patient and operating room staff. Fluoroscopic based image guided surgery systems can be of benefit in predicting the paths of the guide pins and in significantly reducing the amount of radiation exposure. Image guided systems such as those taught in U.S. Pat. Nos. 5,772,594 and 6,285,902, incorporated herein by reference, employ a computer and

a localizing device to track a drill or drill guide and superimpose a trajectory line on fluoroscopic images. U.S. Pat. No. 6,285,902 describes a system in which, preferably, orthopaedic surgical tools outfitted with infrared LEDs are tracked by an optical localizing device. The poses of these tools are determined and graphic representations of the tools are superimposed on standard intraoperative x-ray images. This allows the surgeon to view, in real time, the position of the tool or tools with respect to an imaged body part or another tool or tools. In the preferred embodiment, a drill guide outfitted with infrared LEDs is tracked and the trajectory of its bore is displayed on the x-ray image of the involved bone. This allows a surgeon to accurately predict the trajectory of a guide pin that passes through the bore of the drill guide. The surgeon can see the path each guide pin will take and can improve the accuracy and speed of insertion of the guide pin with only a minimum number of x-ray images. These systems, however, do not provide help in selecting paths that will lead to the desired triangular pattern with proper spacing between screws. On the other hand, a tracked drill guide with multiple bores may be used, but this requires a large incision and does not leave the surgeon with flexibility in the spacing or orientation (e.g., parallel vs. diverging) of the screws.

Fitted protective hip brief Inventor(s): Strobl, Frederick T.; (Wayzata, MN) Correspondence: John C. Reich; Merchant & Gould P.C.; P.O. Box 2903; Minneapolis; MN; 55402-0903; US Patent Application Number: 20020099346 Date filed: March 21, 2002 Abstract: A brief for padding a wearer's hips to reduce the risk of hip fracture. The brief comprises a front panel having first and second side edges and a rear panel having first and second side edges. The first side edge of the rear panel is connected to the first side edge of the front panel, and the second side edge of the rear panel is connected to the second side edge of the front panel, thereby forming first and second opening for receiving the wearer's legs. Shock-absorbing padding lines at least part of the rear panel. The shock-absorbing padding extends from a position proximal the first edge of the rear panel to a position proximal the second side edge of the rear panel and at least to a position between the two leg openings. Excerpt(s): The present invention is directed to a device for protecting a person's hip, and more particularly, to a fitted protective hip brief. Every year in the United States, about 250,000 people suffer from hip fractures. 90% of those people are over the age of 50. As the population of our country ages, the number of people suffering hip fractures is projected to double by the year 2040. Of people who suffer from a hip fracture, only 50-65% regain their previous level of mobility. Additionally, a study of 2624 patients showed that only 24% of people suffering from a hip fracture returned home after recovering a nursing home. An even more tragic result of hip fractures is that 14-36% of elderly patients die within one year after sustaining hip fracture. The majority of hip fractures are caused by trauma rather than weakening of the bone. When a person falls, or takes some other blow to the hip, kinetic energy from the impact is transmitted to the hip bone and causes a fracture. Various devices have been proposed to prevent hip fractures that result from such trauma, but none of these device have achieved any level of widespread acceptance. In fact, one study showed that as few as 24% of the people given hip protectors as part of the study had regularly worn the hip protectors. Possible

reasons that so many people participating in the study failed to wear their hip protectors include poor difficulty of use, poor fit, and questionable efficacy. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •
Growth hormone secretagogue receptor family Inventor(s): Arena, Joseph P.; (Eagleville, PA), Cully, Doris F.; (Scotch Plains, NJ), Feighner, Scott D.; (Highlands, NJ), Howard, Andrew D.; (Park Ridge, NJ), Liberator, Paul A.; (Holmdel, NJ), Schaeffer, James M.; (Westfield, NJ), Van Der Ploeg, Leonardus H. T.; (Scotch Plains, NJ) Correspondence: Merck And CO Inc; P O Box 2000; Rahway; NJ; 070650907 Patent Application Number: 20030166144 Date filed: November 25, 2002 Abstract: Human, swine and rat growth hormone secretagogue receptors have been isolated, cloned and sequenced. Growth hormone secretagogue receptors are new members of the G-protein family of receptors. The growth hormone secretagogue receptors may be used to screen and identify compounds which bind to the growth hormone secretagogue receptor. Such compounds may be used in the treatment of conditions which occur when there is a shortage of growth hormone, such as observed in growth hormone deficient children, elderly patients with musculoskeletal impairment and recovering from hip fracture and osteoporosis. Excerpt(s): This invention relates to a new family of receptors, which includes the growth hormone secretagogue receptors (GHSRs) and growth hormone secretagoguerelated receptors (GHSRRs), nucleic acids encoding these receptors; and to the use of a GHSR to identify growth hormone secretagogues and compounds that modulate GHSR function. Growth hormone (GH) is an anabolic hormone capable of promoting linear growth, weight gain and whole body nitrogen retention. Classically, GH is thought to be released primarily from the somatotroph cells of the anterior pituitary under the coordinate regulation of two hypothalamic hormones, growth hormone releasing factor (GHRF or GRF) and somatostatin. Both GHRF stimulation and somatostatin inhibition of the release of GH occurs by the specific engagement of receptors on the cell membrane of the somatotroph. Recent evidence has been mounting which suggests that GH release is also stimulated by a group of short peptides, the growth hormone releasing peptides (GHRP; GHRP-6, GHRP-2 [hexarelin]) which are described, for example, in U.S. Pat. No. 4,411,890, PCT Patent Pub. No. WO 89/07110, PCT Patent Pub. No. WO 89/07111, PCT Patent Pub. No. WO 93/04081, and J. Endocrinol Invest., 15 (Suppl 4), 45 (1992). These peptides function by selectively binding to distinct somatotroph cell membrane receptor, the growth hormone secretagogue receptor(s) (GHSRs). A medicinal chemical approach has resulted in the design of several classes of orally-active, low molecular weight, non-peptidyl compounds which bind specifically to this receptor and result in the pulsatile release of GH. Such compounds possessing growth hormone secretagogue activity are disclosed, for example, in the following: U.S. Pat. Nos. 3,239,345; 4,036,979; 4,411,890; 5,206,235; 5,283,241; 5,284,841; 5,310,737; 5,317,017; 5,374,721; 5,430,144; 5,434,261; 5,438,136; 5,494,919; 5,494,920; 5,492,916; EPO Patent Pub.

Method and apparatus for reducing femoral fractures Inventor(s): Dietzel, Steven E.; (Peru, IN), Lozier, Antony J.; (Warsaw, IN), Miller, Rick; (South Whitley, IN), Sisk, Billy N.; (Claypool, IN), Thelen, Sarah L.; (North Manchester, IN) Correspondence: Baker & Daniels; 111 E. Wayne Street; Suite 800; Fort Wayne; IN; 46802 Patent Application Number: 20030220641 Date filed: May 23, 2002 Abstract: An improved method and apparatus for reducing a hip fracture utilizing a minimally invasive procedure which does not require incision of the quadriceps. A femoral implant in accordance with the present invention achieves intramedullary fixation as well as fixation into the femoral head to allow for the compression needed for a femoral fracture to heal. To position the femoral implant of the present invention, an incision is made along the greater trochanter. Because the greater trochanter is not circumferentially covered with muscles, the incision can be made and the wound developed through the skin and fascia to expose the greater trochanter, without incising muscle, including, e.g., the quadriceps. After exposing the greater trochanter, novel instruments of the present invention are utilized to prepare a cavity in the femur extending from the greater trochanter into the femoral head and further extending from the greater trochanter into the intramedullary canal of the femur. After preparation of the femoral cavity, a femoral implant in accordance with the present invention is inserted into the aforementioned cavity in the femur. The femoral implant is thereafter secured in the femur, with portions of the implant extending into and being secured within the femoral head and portions of the implant extending into and being secured within the femoral shaft. Excerpt(s): The present invention relates to a method and apparatus for treating hip fractures, and, more particularly, to a method and apparatus for reducing femoral fractures utilizing a minimally invasive procedure. Current procedures utilized to reduce hip fractures generally utilize a side plate/hip screw combination, i.e., a bone plate affixed to a lateral aspect of the femur and having a hip screw operably connected thereto, with the hip screw extending into the femoral head. To properly implant a side plate hip screw, a surgeon must dissect an amount of muscle to expose the femur and operably attach the bone plate and hip screw. Typically, the side plate hip screw requires an incision of about 10-12 cm through the quadriceps to expose the femur. While this approach provides surgeons with an excellent view of the bone surface, the underlying damage to soft tissue, including muscle, e.g., the quadriceps can lengthen a patient's rehabilitation time after surgery. What is needed in the art is a method and apparatus for reducing a hip fracture without requiring incision of soft tissue, including, e.g., the quadriceps.

Multi-slot guide for bone-setting operation for a femoral neck fracture Inventor(s): Kawakami, Fujio; (Ube-shi, JP) Correspondence: Kubovcik & Kubovcik; Suite 710; 900 17th Street NW; Washington; DC; 20006 Patent Application Number: 20030236527 Date filed: June 24, 2002 Abstract: An object of the present invention is to provide a multi-slot guide for a femoral neck fracture bone-setting operation, by which a high level of fixation of, for example, a guide pin to a femoral head part can be obtained with no regard to the size of the femur.During a femoral neck fracture bone-setting operation, in the multi-slot guide 10 for the femoral neck fracture bone-setting operation, pin inserting slots a1, d1 and g1 are selected so as to form a triangle under the condition that each of them may be positioned in the site corresponding to the lateral cortical bone S. Then, the guide pins 13A to 13C are inserted from the base region of the femoral greater trochanter G through the locations having contacts with said lateral cortical bone S into the inner region of the femoral head H via respective pin inserting slots a1, d1 and g1. Consequently, the guide pins 13A to 13C and thus the screws 16A to 16C can be rigidly fixed to the upper region of the femur in match with the size of individual femur. Therefore, earlier application of the load to the affected site becomes possible. Excerpt(s): The present invention relates to a multi-slot guide for bone-setting operation for a femoral neck fracture, and specifically to a multi-slot guide used in the cannulated cancellous hip screw technique. In the operations taken on the femoral neck region for the fracture, in which serious displacement are often observed for the aged persons, a technique of replacing a head part of femur (hereafter, sometimes referred to as femoral head) separated from an upper region of the femur due to the fracture with an artificial femoral head has been frequently used, taking a dim view of the risk of false joint or femoral head necrosis. However, this technique has the following problems. That is, in this technique, bone marrow within the femur is seriously invaded, leading to a poor blood circulation within the bone marrow. Further, since this artificial femoral head has a limited lifetime, and therefore another operation will be necessary to change the artificial femoral head after a certain period has elapsed. This may cause another problem, rising of medical expenses. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Falls and Alzheimer's Disease Source: Mount Sinai Medical Center Alzheimer's Disease Research Center. [Newsletter] p. 1-14. Autumn 1993. Contact: Alzheimer's Disease Research Center. Mount Sinai Medical Center. Box 1230, One Gustave Levy Place, New York, NY 10029-6574. PRICE: Free Subscription. Summary: Instability and falls are common problems of old age. One-third to one-half of the population 65 years old and older fall each year, often with serious consequences, and persons with Alzheimer's disease (AD) are not exempt from fall-related problems. Aside from behavioral problems, falls and the risk of injury are a major concern of family members of AD patients. The most serious results of falls among AD patients are premature death, hip fracture, and complications due to immobility related to injuries received in falls. The author addresses risk factors leading to falls, such as impaired physical functions, adverse medication effects, and specific cognitive and systemic effects inherent to AD. Further addressed are ways of modifying fall risk factors, first by medical evaluation to identify fall risk factors, followed by changing medication doses, exercising, changing footwear, and modifying the environment by removing obstacles or problematic furnishings and improving lighting. Special attention should be paid to bed and chair height, placement of bars for support, and providing non slip surfaces in bathrooms and near beds. Modifications should be done to provide a safe environment without making too many changes, as AD patients have difficulty learning new tasks, such as using bathtub grab bars.
Academic Periodicals covering Hip Fracture Numerous periodicals are currently indexed within the National Library of Medicine’s PubMed database that are known to publish articles relating to hip fracture. In addition to these sources, you can search for articles covering hip fracture that have been published by any of the periodicals listed in previous chapters. To find the latest studies published, go to http://www.ncbi.nlm.nih.gov/pubmed, type the name of the periodical into the search box, and click “Go.”

CHAPTER 8. RESEARCHING MEDICATIONS Overview While a number of hard copy or CD-ROM resources are available for researching medications, a more flexible method is to use Internet-based databases. Broadly speaking, there are two sources of information on approved medications: public sources and private sources. We will emphasize free-to-use public sources.
U.S. Pharmacopeia Because of historical investments by various organizations and the emergence of the Internet, it has become rather simple to learn about the medications recommended for hip fracture. One such source is the United States Pharmacopeia. In 1820, eleven physicians met in Washington, D.C. to establish the first compendium of standard drugs for the United States. They called this compendium the U.S. Pharmacopeia (USP). Today, the USP is a nonprofit organization consisting of 800 volunteer scientists, eleven elected officials, and 400 representatives of state associations and colleges of medicine and pharmacy. The USP is located in Rockville, Maryland, and its home page is located at http://www.usp.org/. The USP currently provides standards for over 3,700 medications. The resulting USP DI Advice for the Patient can be accessed through the National Library of Medicine of the National Institutes of Health. The database is partially derived from lists of federally approved medications in the Food and Drug Administration’s (FDA) Drug Approvals database, located at http://www.fda.gov/cder/da/da.htm. While the FDA database is rather large and difficult to navigate, the Phamacopeia is both user-friendly and free to use. It covers more than 9,000 prescription and over-the-counter medications. To access this database, simply type the following hyperlink into your Web browser: http://www.nlm.nih.gov/medlineplus/druginformation.html. To view examples of a given medication (brand names, category, description, preparation, proper use, precautions, side effects, etc.), simply follow the hyperlinks indicated within the United States Pharmacopeia (USP). Below, we have compiled a list of medications associated with hip fracture. If you would like more information on a particular medication, the provided hyperlinks will direct you to ample documentation (e.g. typical dosage, side effects, drug-interaction risks, etc.). The
140

following drugs have been mentioned in the Pharmacopeia and other sources as being potentially applicable to hip fracture: Fondaparinux •
Systemic - U.S. Brands: Arixtra http://www.nlm.nih.gov/medlineplus/druginfo/uspdi/500365.html
Commercial Databases In addition to the medications listed in the USP above, a number of commercial sites are available by subscription to physicians and their institutions. Or, you may be able to access these sources from your local medical library.
Mosby’s Drug Consult Mosby’s Drug Consult database (also available on CD-ROM and book format) covers 45,000 drug products including generics and international brands. It provides prescribing information, drug interactions, and patient information. Subscription information is available at the following hyperlink: http://www.mosbysdrugconsult.com/. PDRhealth The PDRhealth database is a free-to-use, drug information search engine that has been written for the public in layman’s terms. It contains FDA-approved drug information adapted from the Physicians’ Desk Reference (PDR) database. PDRhealth can be searched by brand name, generic name, or indication. It features multiple drug interactions reports. Search PDRhealth at http://www.pdrhealth.com/drug_info/index.html. Other Web Sites Drugs.com (www.drugs.com) reproduces the information in the Pharmacopeia as well as commercial information. You may also want to consider the Web site of the Medical Letter, Inc. (http://www.medletter.com/) which allows users to download articles on various drugs and therapeutics for a nominal fee. If you have any questions about a medical treatment, the FDA may have an office near you. Look for their number in the blue pages of the phone book. You can also contact the FDA through its toll-free number, 1-888-INFO-FDA (1-888-463-6332), or on the World Wide Web at www.fda.gov.

Coffee Break: Tutorials for Biologists18 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.19 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.20 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/.
18 Adapted 19
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. 20 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.
149
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 hip fracture 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 hip fracture. 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 hip fracture. 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 “hip fracture”:

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 hip fracture. 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.

everyday activities. The number of falls and the severity of injury resulting from falls increases as people get older. The most common serious injuries are head injuries, wrist fractures, spine fractures, and hip fractures. The brochure first provides general facts about falls, and discusses the financial costs of falls among older people, and the role of osteoporosis in fractures. The fact sheet then lists suggestions for safety precautions in five areas of the home: stairs, bathroom, kitchen, living area, and bedroom. Also listed are suggestions for footwear that can help prevent falls. The last section of the brochure lists medical and personal risk factors that can increase problems with falling, including vision loss, hearing loss, and balance difficulties. The brochure concludes with a list of suggestions for what to do after a fall occurs. Colorful line drawings illustrate the brochure. The National Guideline Clearinghouse™ The National Guideline Clearinghouse™ offers hundreds of evidence-based clinical practice guidelines published in the United States and other countries. You can search this site located at http://www.guideline.gov/ by using the keyword “hip fracture” (or synonyms). The following was recently posted: •

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 hip fracture. 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. Additional Web Sources A number of Web sites are available to the public that often link to government sites. These can also point you in the direction of essential information.

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.21
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: A term originally used to refer to the heat-labile factor in serum that causes immune cytolysis, the lysis of antibody-coated cells, and now referring to the entire functionally related system comprising at least 20 distinct serum proteins that is the effector not only of immune cytolysis but also of other biologic functions. 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.
