The overall goal of the Duke Claude D. Pepper Older Americans Independence Center (Duke OAIC) is to support research and training that improves the independence of older Americans. Our primary focus is understanding and optimizing reserve and resilience. Our approach is founded on the insight that independence in older adults is related to an individual’s ability to withstand or recover from functional decline following acute or chronic health stressors. Our overall strategy for the OAIC is to serve as a sustained resource to our investigators through a broad range of training and research studies; the goal will be to address knowledge gaps in our focus with an emphasis on translational and interdisciplinary research. We recruit and develop early stage investigators in aging research related to our focus and utilize the substantial strengths of the Duke academic and health system environment to advance our focus.

Our goals are accomplished through the synergistic activities of the Leadership and Administration Core (LAC), Research Education Component (REC), Pilot/Exploratory Studies Core (PESC), and 3 Resource Cores: Molecular Measures Core (MMC), Physical Measures Core (PMC), and Analysis Core (AC).

AIMS of the Duke Pepper Center
  1. To better understand and optimize reserve and resilience in older adults through an integrated research program.
  2. To develop and evaluate new methods that advance the study of reserve and resilience.
  3. To identify and develop the next generation of researchers who will become leaders in aging and geriatrics research related to the Duke OAIC focus.
  4. To support pilot studies through the PESC that acquire information needed to select or design successful, more definitive research studies related to the Duke OAIC focus.

Duke Pepper Center Researchers Investigate Quantitative Muscle Ultrasound (QMUS) as an Alternative Reliable, Inexpensive Method to Measure Muscle Health
Muscle health is recognized for its critical role in the functionality and well-being of older adults. Duke Pepper researchers Lisa Hobson-Webb, MD and Amy M. Pastva, PT, PhD, along with the director of the Michael W. Krzyzewski Human Performance Lab, Timothy Sell, PT, PhD, examined the reliability of quantitative muscle ultrasound (QMUS), standard electrical impedance myography (sEIM), and handheld electrical impedance myography (hEIM) measures of anterior thigh musculature in the December 2018 Special Issue of Geriatrics: Geriatric Assessment: Multidimensional, Multidisciplinary and Comprehensive. Multiple correlations with measures of strength and body composition were noted for each method. These point-of-care technologies may provide an alternative means of measuring health compared with more expensive traditional scan technologies.

Duke Pepper Center Researcher Stresses the Importance of Stored Biospecimen Research As Complementary Investigative Path With Long-Term Clinical Trials on Human Healthspan
Duke Pepper researcher Daniel Belsky, PhD and Amal Harrati, PhD, a Stanford researcher, discuss the relevance of biospecimen research in their article, To the freezers! Stored biospecimens from human randomized trials are an important new direction for studies of biological aging, in the January 2019 issue of The Journals of Gerontology, Biological Sciences & Medical Sciences. Clinical trials testing effects on healthspan-relevant endpoints, like age-at-onset of chronic disease or disability, require many years or even decades of follow-up. While the field awaits a new generation of human trials of geroprotective therapies, analysis of stored biospecimens from now-completed studies can help test candidate surrogate endpoints in briefer research timeframes.

Duke Pepper Center Researchers Investigate Relationships of SES and Physical Functioning
Duke Pepper researchers, led by Grace Noppert, PhD, examined associations between multiple early and late life SES indicators with physical function. The research team discovered higher participant education and household income were associated with increased physical function. In an age-stratified analysis, SES disparities widened with increasing age among those in the two younger strata: lower SES was associated with worse physical function. Their findings highlight the significance of considering multiple dimensions of the social environment as important correlates of physical functioning over the life course.

Duke Pepper Center Physical Measures Core Co-Leader Investigates Benefits of Exercise in Older Vets with PTSD
Katherine S. Hall, PhD, Assistant Professor in the Division of Geriatrics, is launching a pilot study to learn if increased physical activity among older Vets with PTSD will help ease their symptoms. Veterans with PTSD have been shown to have low rates of exercise, and many report that they don’t work out at all. The heart of the study is a supervised 12-week exercise plan called the “Warrior Wellness” program. It consists of activities focusing on strength, flexibility, balance, and endurance training. Part of what makes the program special is its extensive exercise battery that can be adapted to individual musculoskeletal ailments.
