Jennifer Schrack, PhD

Congratulations to Dr. Jennifer Schrack of COAH, named as new Co-PI of NHATS!

Associate Professor of Epidemiology, Jennifer A. Schrack, PhD, MS, with the Johns Hopkins Bloomberg School of Public Health, recently ascended to a Co-PI leadership role with the  National Health and Aging Trends Study (NHATS), which systematically gathers information over time from a nationally representative sample of Medicare beneficiaries ages 65 and older.

Regarding this significant research role, Dr. Schrack said, “I look forward to continuing what has been done so well by NHATS for the past decade, and to looking for ways to expand and advance our understanding of disability in late life.”  Annual NHATS interviews with participants are critically important to collect insightful information about the physical, social, and economic well-being of older and differently abled adults, such as: the physical, social, technological and service environment; tests and self-reports of physical and cognitive capacity; use of assistive devices and rehabilitation services; help received with daily activities (self-care, household, and medical); and participation in valued activities. Additionally, participants’ family members may be interviewed about the quality of end of life care that was received by NHATS participants who have died. Dr. Schrack is well-qualified for NHATS leadership. Her primary research focuses on the role of physiological factors in maintaining mobility and preventing disability with aging. She directs the Epidemiology of Aging Track and co-leads the Accelerometry Research Core at the Johns Hopkins Center on Aging and Health.  With a Masters in Exercise Physiology from the University of Michigan and a PhD in Epidemiology from the Johns Hopkins Bloomberg School of Public Health, Dr. Schrack has extensive clinical research as an exercise physiologist, with an emphasis on the assessment physical function, energy expenditure, and physical activity using accelerometers.

In addition to previously being an investigator with NHATS, Dr. Schrack is the PI of a U01 from the NIA to delineate associations among energy regulation, physical activity, and Alzheimer’s disease, and the Co-PI of a R01 from the NIA to investigate sensory and motor contributions to the development of preclinical Alzheimer’s disease. In addition, she is a co-investigator of the Baltimore Longitudinal Study of Aging (BLSA), the Study of Physical Resiliency iN Geriatrics (SPRING), the Study to Understand vitamin D and falls in You (STURDY), the Aging, Cognition, and Hearing Evaluation in Elders (ACHIEVE) Randomized Trial, and the Atherosclerosis Risk in Communities (ARIC) study.  Dr. David Roth, the Director of the Center on Aging and Health at Johns Hopkins, lauded the selection of Dr. Schrack for her new leadership role in NHATS.  Dr. Roth noted that “Dr. Schrack is an extremely talented, committed, and influential scholar who also has outstanding organizational and supervisory skills.  She will do a great job in leading NHATS in collaboration with the other exceptional researchers working on that very important project.”

The Johns Hopkins University Bloomberg School of Public Health and the University of Michigan’s Institute for Social Research lead NHATS with support from the National Institute on Aging, with data collection via Westat. Dr. Vicki Freedman from the Institute for Social Research at the University of Michigan is NHAT’s senior co-PI; Dr. Schrack steps into this role following the death of her friend and Bloomberg School of Public Health colleague, Dr. Judith Kasper, the former NHATS Co-PI from Johns Hopkins, who deceased on August 5, 2021 from a heart attack at her home in Bolton Hill, Baltimore; you may read Dr. Kasper’s obituary here.

COAH Researchers Contribute to Study Finding Racial Disparities in Stroke Medication Management & Underscore Caregivers’ Role in Preventing Another Ischemic Stroke

Stroke is a major cause of morbidity and mortality in the US, and a prior stroke is one of the biggest risk factors for future stroke events. Stroke survivors face a 13% increased risk of a subsequent stroke in the first year after stroke, and over 40% experience a second stoke within 10 years. Prior stroke history is also a major risk factor for other cardiovascular events and mortality. Preventing a second stroke is critically important among initial stroke survivors, and the use of secondary prevention medications can reduce the risk of additional stroke event by more than 80%.

“After a stroke, compliance with prescribed medications dramatically reduce the chance of another cardiovascular event. Having an engaged caregiver improves medication adherence for stroke survivors. We need to do more to understand why Black stroke survivors stop antithrombotic medications more frequently than White stroke survivors and address potential racial disparities in recurrence rates,” said lead researcher Orla C. Sheehan, MD, PhD at the Johns Hopkins Center on Aging and Health (COAH) and team examined health care disparities between Black and White stroke survivors based on data from the Caring for Adults Recovering from the Effects of Stroke (CARES) study, an ancillary study of the national REasons for Geographic and Racial Differences in Stroke (REGARDS). The national REGARDS study was designed to identify the causes of regional and racial disparities in stroke mortality, and CARES data enabled the team to analyze information among 172 stroke survivors paired with 160 caregivers. Johns Hopkins researchers Chelsea Liu, Dr. Jin Huang, and COAH Director Dr. David L. Roth were also on this team.

They found that 10 months after hospital discharge, Black stroke survivors were more than twice as likely as White stroke survivors to have discontinued antithrombotic medications, known to help prevent another ischemic event, despite having similar prescription rates at the time of hospital discharge. Antithrombotic usage decreased by 18% for Blacks compared to only 8% for Whites. These findings suggest that Blacks may be at an increased risk of experiencing a second stroke compared to Whites. Delving deeper into the data, they also observed that Black stroke survivors were less likely than White stroke survivors to live with a family caregiver. Interestingly, researchers found that antihypertensive persistence was high regardless of race; the research team credit that fact to effective public health campaigns, such as the National High Blood Pressure Education Program.

“In our cohort, persistence to secondary preventive medication regimens was high likely due to the presence of an engaged caregiver. Routine involvement of caregivers in medication management at the time of hospital discharge and during follow up has the potential to increase adherence to secondary prevention regimens. Use of both antithrombotic and lipid lowering medications fell over time in our population, likely increasing the subsequent stroke risk in those participants—particularly Black stroke survivors who were significantly more likely to discontinue antithrombotic medications The effect of changes in patterns of medication usage on health outcomes particularly in Blacks deserves continued investigation,” added Sheehan.

Sheehan and her team underscore that vigilant caregiver help with medication management is critically important to increase adherence to secondary stroke prevention medications, thereby decreasing the odds of their loved-one having another stroke event. Also, the research team suggests that public health campaigns focused on groups of medications—not just blood pressure medications—may help educate stroke survivors about how important they are to preventing secondary vascular conditions. Moreover, the team believes that the effect of changes in patterns of medication usage on health outcomes, especially in Blacks, warrants further research.

Drs. Sheehan and Roth are available for interview.

Sarah-Szanton

Congratulations, Dean Szanton!

We at COAH join the thunderous rounds of applause in celebrating that Dr. Sarah Szanton was named as the new Dean of the Johns Hopkins School of Nursing. She began her term on August 25th to much fanfare. Indeed, “I’m a Sarah Fan” signs were waving at the State of the School speech she delivered on the first day of her term. And there are many reasons to be a fan of Dean Szanton. She co-developed the CAPABLE program, which helps seniors age in the community; CAPABLE received a lot of attention earlier this year under the new White House administration as a model of how communities nation-wide can better respond to the needs of our older adults, and it has now spread to 44 communities in 23 states!
