Methods: 51 community-dwelling adults, 65 years or older, completed a power test using a pneumatic leg press (LP), the Short Physical Performance Battery (SPPB) that includes a test of balance, usual walking speed, and chair stand tests; Timed …

New Evidence For P-Gp-Mediated Export Of Amyloid-Β Peptides In Molecular, Blood-Brain Barrier And Neuronal Models, Amanda B. Chai, Anika M. S. Hartz, Xuexin Gao, Alryel Yang, Richard Callaghan, Ingrid C. Gelissen

Sanders-Brown Center on Aging Faculty Publications

Defective clearance mechanisms lead to the accumulation of amyloid-beta (Aβ) peptides in the Alzheimer’s brain. Though predominantly generated in neurons, little is known about how these hydrophobic, aggregation-prone, and tightly membrane-associated peptides exit into the extracellular space where they deposit and propagate neurotoxicity. The ability for P-glycoprotein (P-gp), an ATP-binding cassette (ABC) transporter, to export Aβ across the blood-brain barrier (BBB) has previously been reported. However, controversies surrounding the P-gp–Aβ interaction persist. Here, molecular data affirm that both Aβ₄₀ and Aβ₄₂ peptide isoforms directly interact with and are substrates of P-gp. This was reinforced ex vivo by the …

Neither “Post-War” Nor Post-Pregnancy Paranoia: How America’S War On Drugs Continues To Perpetuate Disparate Incarceration Outcomes For Pregnant, Substance-Involved Offenders, Becca S. Zimmerman

Pitzer Senior Theses

This thesis investigates the unique interactions between pregnancy, substance involvement, and race as they relate to the War on Drugs and the hyper-incarceration of women. Using ordinary least square regression analyses and data from the Bureau of Justice Statistics’ 2016 Survey of Prison Inmates, I examine if (and how) pregnancy status, drug use, race, and their interactions influence two length of incarceration outcomes: sentence length and amount of time spent in jail between arrest and imprisonment. The results collectively indicate that pregnancy decreases length of incarceration outcomes for those offenders who are not substance-involved but not evenhandedly -- benefitting white …

Using The Memorial Sloan Kettering Frailty Index To Identify Patients At High Risk For Postoperative Intensive Care Unit Admission, Specialized Advanced Care Unit Admission, And 30-Day Readmission, Timothy J. Donoghue

Theses and Dissertations

Frailty is roughly defined as an accumulation of physiological, emotional, cognitive, and social deficits that impair a person’s response to stressful events. A frailty diagnosis has been associated with poor outcomes following surgical procedures. Cancer surgical patients aged 65 or older represent a vulnerable population susceptible to being frail and the potential associated complications that can accompany frailty. Measuring frailty is an objective risk assessment that identifies increased risk better than age or American Society of Anesthesiologists Physical Status (ASA-PS) score such that frailty can independently predict poor surgical outcomes.

Frailty is not specifically a result of having cancer, disability, …

The Impact Of Social Isolation And Cognitive Decline In Older Adults: A Systematic Literature Review, Jody L. Doll-Wilhelm

How Does Direct Volunteering Affect The Onset Of Alzheimer’S Dementia In Elderly Patients With Preexisting Cardiac Comorbidities?, Sneha R. Gade

UROP Posters

Alzheimer's Dementia is a disease that affects memory, thinking, and behavior. The Alzheimer's Association reported Alzheimer's as the sixth-leading cause of death in the United States, and a cure does not exist. Donepezil, a cholinesterase inhibitor drug, is frequently prescribed to treat Alzheimer's disease. Still, patients must continuously take the medication for years to receive any measurable improvement in quality of life after developing Alzheimer's Dementia. Further, research shows prolonged use of Donepezil can lead to other health problems, such as QTc prolongation, for cardiac disease patients. Therefore, the effectiveness of non-drug interventions, such as volunteering to prevent the disease's …

Benefits Of Equine-Based Therapy For Individuals With Dementia, Lauren Fearn

Student Capstone Papers

Individuals living with dementia typically experience progressive, cognitive, and functional decline which limits their ability to communicate and fully perform activities (Pimouguet el al., 2019). Horses have been shown to benefit individuals with dementia by improving well-being, physical health, functional capacity, and social relationships (Fields et. al., 2019).

A 6-week OT-based virtual equine-assisted activities program was conducted to determine if participation in equine-assisted activities could improve the quality of life of individuals with dementia. Outcomes of the program resulted in improvements in mood, energy level, engagement, communication, memory, socialization, and overall quality of life.

Revisiting The Role Of Physicians In Assisted Living And Residential Care Settings, Sarah Dys, Lindsey Smith, Ozcan Tunalilar, Paula C. Carder

Institute on Aging Publications

As the United States population ages, a higher share of adults is likely to use long-term services and supports. This change increases physicians’ need for information about assisted living and residential care (AL/RC) settings, which provide supportive care and housing to older adults. Unlike skilled nursing facilities, states regulate AL/RC settings through varying licensure requirements enforced by state agencies, resulting in differences in the availability of medical and nursing services. Where some settings provide limited skilled nursing care, in others, residents rely on resident care coordinators, or their own physicians to oversee chronic conditions, medications, and treatments. The following narrative …

Sanders-Brown Center on Aging Faculty Publications

Stable isotope-resolved metabolomics (SIRM) is a powerful tool for understanding disease. Advances in SIRM techniques have improved isotopic delivery and expanded the workflow from exclusively in vitro applications to in vivo methodologies to study systemic metabolism. Here, we report a simple, minimally-invasive and cost-effective method of tracer delivery to study SIRM in vivo in laboratory mice. Following a brief fasting period, we orally administered a solution of [U-¹³C] glucose through a blunt gavage needle without anesthesia, at a physiological dose commonly used for glucose tolerance tests (2 g/kg bodyweight). We defined isotopic enrichment in plasma and tissue at …
