Claude D. Pepper Older Americans Independence Center (OAIC)

To understand and optimize reserve and resilience



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.

Abrams Award in Geriatric Clinical Pharmacology. The award recognizes scientists who have improved clinical care or therapies for older adults through research and honors an investigator in geriatric clinical pharmacology for outstanding contributions to the field.
Data Integration Working Group (DIWG) Semi-monthly (2nd and 4th Thursdays)
The Duke Pepper Data Integration Working Group meets the 2nd and 4th Thursday of each month. The DIWG is open to members of the Duke community and is a wonderful inlet for individuals who want to learn more about the resources and opportunities of the Duke Pepper Center.
When: Thursday June 28th, 9:30-11:00am
Where: Learning Lab 1502 Blue Zone, Duke Clinics
Topic: Rasheeda Hall, MD will practice a talk in preparation for her presentation to the Harold Amos Medical Faculty Development Program Award Committee on July 12.
Looking Ahead: July: No meetings.
August 8th: Daniel Parker, MD will discuss his latest PALS analyses.
Pepper Researcher Receives NIH Grant To Lead the Duke Center for REsearch to AdvanCe Healthcare Equity (REACH)
Kimberly Johnson, MD, has received one of 12 NIH awards to fund a specialized research center designed to conduct multidisciplinary research, research training and community engagement activities focused on improving minority health and reducing health disparities.
Dr Johnson also received funding from the Patient-Centered Outcomes Research Institute (PCORI) to study the barriers and facilitators of advance-care planning for different racial groups: Reducing Disparities in the Quality of Palliative Care for Older African Americans through Improved Advance Care Planning (EQUAL ACP).

Duke Pepper Center hosts Spring 2018 workshop: Physical Function Assessment in Older Adults
The Duke Pepper Physical Measures Core hosted a half-day workshop in May which highlighted functional assessments that can be utilized across the continuum of functional ability and implemented across a variety of settings (e.g., resource-rich vs. resource-limited, outpatient vs. inpatient). Participants came from several departments within the School of Medicine and the Health System to gain more knowledge and practical expertise in the implementation of performance-based measures of physical function in research.

An Innovative Approach to Building Posttraumatic Resilience in Late Life: The Warrior Wellness Exercise Study for Older Veterans with PTSD
Katherine S. Hall, PhD, and her colleagues summarized the current status of the Warrior Wellness Study, a randomized controlled exercise trial for older veterans with PTSD. If the Warrior Wellness intervention is found to be effective at helping older veterans with PTSD improve resilience and achieve physical and psychological outcomes, this group-based exercise program could be expanded and implemented into clinical practice.
Age-Related Adverse Inflammatory and Metabolic Changes Begin Early in Adulthood
Daniel Parker, MD, and his team presented cross-sectional data which demonstrate the onset – as early as the fourth decade of age – of abnormalities of immune and metabolic biomarkers known to be associated with impaired physical function, morbidity, and mortality in older adults.
Macrophage-induced Meteorin-like secretion: A potential regenerative therapy for aging muscle
James P. White, PhD, and a research team across institutions presented studies that identified Meteorin-like (Metrnl) as a critical regulator in muscle regeneration and a viable therapeutic to enhance regeneration in aged muscle.
Duke Health's Clinical Practice Today features Duke Pepper Research project To Improve Post-Surgery Outcomes in Seniors
The Duke Pepper research initiative POSH (Perioperative Optimization of Senior Health) is featured in a recent article of Clinical Practice Today, a monthly bulletin of Duke Health. The pre-surgical exercise project focuses on patients older than age 65 who are scheduled for surgery but not currently exercising.
Researchers are currently analyzing whether increased activity before surgery, as measured in step counts, improves resilience and is correlated with a more positive recovery from surgery.

Duke Pepper Center Research Selected as Editor's Choice in Journals of Gerontology, Biological Sciences & Medical Sciences Special Edition On Caloric Restriction and the Biology of Aging
Duke Pepper researchers Daniel Belsky, PhD, Kim Huffman, MD, PhD, Carl Pieper, DrPH, and William Kraus, MD are among the co-authors of the Editor’s Choice selection in the January 2018 issue of The Journals of Gerontology, Biological Sciences & Medical Sciences, which focuses on Caloric Restriction and the Biology of Aging. Their article, Change in the Rate of Biological Aging in Response to Caloric Restriction: CALERIE Biobank Analysis, is a retrospective examination of data from the National Institute on Aging CALERIE randomized trial. Their analysis across 3 time points found that caloric restriction slowed biological aging as measured by Klemera–Doubal Method Biological Age and homeostatic dysregulation.
