“Penn State Clinical and Translational Science Institute”

Major Goals: Advancing clinical and translational science to improve health and defeat disease requires a unique set of expertise and supports—ranging from capacity for effective multidisciplinary team science, to a cohesive infrastructure of research IT and data sharing, novel approaches to training a new and diverse workforce, and strengths in building partnerships with the varied communities we serve. We propose to build on the foundation we have established at Penn State, to further expand our capacity to motivate and support multidisciplinary translational research that reaches across our University and to other institutions, and educates a new generation of the workforce to achieve rigorous, high impact, clinical and translational science.

R01AG056538 (Derby & Buxton, mPI) 2019-2023 icon-olus-circle


“Application of ambulatory methods for assessing short- and long-term associations of sleep health with cognitive decline in older adults”

Major Goals: This project builds upon the strengths of a well-established Program Project, the Einstein Aging Study (EAS: NIA P01 AG003949). The EAS will provide longitudinal measures of both traditional clinic-based cognitive assessments and novel, ecologically meaningful ambulatory cognitive assessments on 500 individuals age 70+. Annual assessments also include medical history and cardiovascular risk factors. By adding objective measures of sleep (actigraphy, oximetry) to this cohort, we will examine the associations of sleep with cognitive decline and MCI and the role of inflammatory and vascular mechanisms that may underlie these associations.

U01 AG027669 (Berkman, PI) 2008-2015

“Evaluating the Health Benefits of Workplace Policies and Practices - Phase II”
Although the prevalence of “family-friendly” policies in US workplaces has increased dramatically, few have been studied using scientifically sound designs. To address this, NIH and CDC formed the Work, Family, and Health Network (WFHN). During Phase 1, WFHN designed and conducted multiple pilot and feasibility studies. For Phase 2, the WFHN has been called upon to implement an innovative intervention based on Phase I pilot studies that is designed to increase family-supportive supervisor behaviors and employee control over work, and to evaluate the intervention using a group randomized experimental design.

“Sleep Actigraphy in a Trucker Weight Loss Intervention Trial”
The purpose of this subproject is to train researchers on the scoring of de-identified sleep actigraphy data to eventually determine the effects of a social support intervention in truckers. Long-haul truck drivers have overweight and obesity rates almost 20% higher than the general population. Obesity has established mortality and disease consequences, including heart disease, diabetes, and sleep apnea. Driver health is also a public safety hazard because obesity and sleep apnea increase the risk of deadly crashes. Despite the growing health crisis, there is a lack of effective weight loss and health promotion interventions for truck drivers. To address this research gap we developed an innovative intervention that is integrated with the job structure and modern technologies of truck driving.
