Below is a brief description of major research programs sponsored by the UW Division of Geriatrics and the Madison GRECC:
Under the leadership of Sanjay Asthana, MD, the Division sponsors a nationally-recognized, well-funded, translational research program in Alzheimer’s disease and related illnesses. The program is supported by numerous grants from the NIH, VA, philanthropic foundations, and the pharmaceutical industry, and formed the basis for a recently funded P50 ADRC. The major focus of numerous ongoing research studies in the WCMP relate to various aspects of Alzheimer’s disease, including its neurobiology (Drs. Atwood, Puglielli), preclinical diagnosis (Dr. Johnson), prevention (Dr. Carlsson), and treatment (Drs. Asthana, Gleason).
Under the leadership of Rozalyn Anderson PhD, the major focus of this internationally-renowned laboratory-based research program is to investigate the potential effects of caloric restriction and oxidative stress on aging and age-associated illnesses. The program involves molecular biology studies on postmitotic tissues, including heart, skeletal muscles and the brain. Dr. Weindruch and his collaborators have published several seminal research papers, and are at the forefront of caloric restriction research involving non-human primates and rodents. Research support for the program has been received from various resources, including the NIH, the Department of Veterans Affairs (VA), philanthropic foundations and the pharmaceutical industry.
Dissemination of Evidence-Based Prevention Programs:
Led by Dr. Jane Mahoney, this work centers on effective ways to get evidence based programs into practice. Dr. Mahoneyis the Director of the Community-Academic Aging Research Network, which facilitates community-based aging research by connecting research faculty from UW-Madison with community partners from Wisconsin’s Aging Network. She is also the Executive Director of the Wisconsin Institute for Healthy Aging, a non-profit organization that disseminates evidence-based prevention programs for older adults to community partners and health care systems in Wisconsin and nationally.
JoAnne Robbins, PhD, full tenured Professor of Medicine at the UW School of Medicine and Public Health and Associate Director of Research at the Madison VA GRECC, leads this preeminent program that conducts novel and innovative research in the pathobiology, prevention and treatment of dysphagia in older adults. The research focus of this program is on dysphagia associated with healthy aging (sarcopenia) and common illnesses, including stroke and dementia, and the prevention of aspiration and pneumonia. The program is supported by research grants from the NIH, SBIR, USDA, and the VA.
Various programs designed to reduce incidence of falls in older adults are developed and researched in this area under the leadership of Dr. Jane Mahoney. Her current work includes developing a cultural and linguistic translation of a group program for the Hispanic community as well as an online maintenance program for graduates of the Stepping On fall prevention program. In addition she is collaborating with the Department of Engineering to develop an online intervention to keep older adults in their homes longer and reduce falls, as well as working with the Centers for Disease Control and Prevention (CDC) regarding an online falls prevention program for a clinical setting.
Under the leadership of Molly Carnes, MD, MS, areas of training and research have focused on investigations aimed at increasing the diversity of the scientific and medical workforce as a way of improving women's health across the lifespan. Support for research and training includes grants from the NIH, NSF and the VA.
The major objective of this preeminent research program is to understand the pathophysiology and treatment of bone disease using various clinical investigative and basic science approaches. Under the leadership of Neil Binkley, MD, the major focus of numerous ongoing clinical studies in this program is to characterize the potential beneficial effects of alendronate, parathyroid hormone (PTH), and vitamin K on bone mineral density and markers of bone turnover. The basic science studies focus on the PHEX/Phex gene cloning, mutations, and tissue localization. Similar to others, this program is also supported by several peer-reviewed grants and those from the pharmaceutical industry.
Sleep Disorders in the Elderly:
Under the direction of Steven Barczi, MD, the Associate Director for Education and Evaluation at the Madison GRECC, this program investigates the potential adverse effects of sleep disorders on chronic disease, vascular status and cognitive function of older adults. Specific areas of investigation include sleep apnea, comorbid insomnia and sleep changes in dementia. Physiological research and clinical research occur in the setting of a nationally recognized VA respiratory physiology laboratory, two state-of-the-art clinical laboratories and geriatric-focused sleep clinics at both the UW (Wisconsin Sleep Center) and Madison VA. The GRECC and Madison VA hospital co-sponsor a clinical and research fellowship in Sleep Medicine that is jointly affiliated with the UW Center for Sleep Medicine and Sleep Research within the School of Medicine.
Transitional Care Research:
One of the emerging areas of novel research in the UW Division of Geriatrics relates to transitional care studies. Under the visionary leadership of Amy Kind, MD, PhD, an Assistant Professor in the Geriatrics Division and a health services/implementation investigator, the major focus of this program is on patient safety during transitions between health care settings, particularly for highly vulnerable older adult populations. As part of this research, the transitional care program has designed and disseminated clinical interventions which improve care transitions and between-facility communication at the time of hospital discharge for high-risk older adult patients, including those with dementia and those in low-resource settings. One of these interventions, the Coordinated-Transitional Care (C-TraC) Program, is a low-cost, mostly phone-based intervention designed to improve hospital-to-home transitions for patients with dementia and other high-risk conditions. Additionally, the program is sponsoring studies using Medicare-claims data to focus on issues of rehospitalization in high-risk populations, including the role of socioeconomic disadvantage in 30-day rehospitalization for older adults. Mixed method (i.e., quantitative/qualitative) research is also being conducted examining the impact of discharge communication quality on system-to-system transitions, particularly for patients discharged to nursing homes.
Overall, the UW Division of Geriatrics sponsors both laboratory-based and translational research studies of pivotal clinical significance and relevance. These studies are supported by numerous peer-reviewed grants from the NIH and the VA, and target enhanced care for millions of elderly patients suffering from chronic disabling illnesses. A substantial infrastructure exists to train and mentor junior investigators as they pursue their academic goals. The overarching mission of the Division of Geriatrics-sponsored research program is to better understand the pathobiology of age-associated diseases, and to reduce the cost and burden of illness as well as enhance the quality of life of older adults.
