Background

Older adults receive treatment for fall injuries in both inpatient and outpatient settings. The effect of persistent polypharmacy (i.e. using multiple medications over a long period) on fall injuries is understudied, particularly for outpatient injuries. We examined the association between persistent polypharmacy and treated fall injury risk from inpatient and outpatient settings in community-dwelling older adults.

Methods

The Health, Aging and Body Composition Study included 1764 community-dwelling adults (age 73.6 ± 2.9 years; 52% women; 38% black) with Medicare Fee-For-Service (FFS) claims at or within 6 months after 1998/99 clinic visit. Incident fall injuries (N = 545 in …

A Survey Of Delirium Self-Reported Knowledge And Practices Among Emergency Physicians In The United States, Anita N. Chary, Adriane Lesser, Sharon K. Inouye, Christopher R. Carpenter Md, Msc, Amy R. Stuck, Maura Kennedy

Journal of Geriatric Emergency Medicine

Objective: This study aimed to evaluate United States emergency physicians’ self-reported knowledge and practices regarding the detection, prevention, and management of delirium, a common and deadly syndrome that disproportionately affects older emergency department (ED) patients. Knowledge and practices of the broader emergency physician community about these priority topics in geriatric emergency medicine are understudied.

Design: Electronic self-administered online survey

Setting: United States

Participants: One-hundred ninety-seven emergency physicians of the American College of Emergency Physicians Emergency Medicine Practice Research Network

Measures: Descriptive statistics were generated from survey responses.

Results: Of 734 physicians in the research network who were sent the …

Overcoming The Covid-19 Pandemic For Dementia Research: Engaging Rural, Older, Racially And Ethnically Diverse Church Attendees In Remote Recruitment, Intervention And Assessment, Lisa Kirk Wiese, Ishan C. Williams, Nancy E. Schoenberg, James E. Galvin, Jennifer Lingler

Background: Access to cognitive screening in rural underserved communities is limited and was further diminished during the COVID-19 pandemic. We examined whether a telephone-based cognitive screening intervention would be effective in increasing ADRD knowledge, detecting the need for further cognitive evaluation, and making and tracking the results of referrals.

Method: Using a dependent t-test design, older, largely African American and Afro-Caribbean participants completed a brief educational intervention, pre/post AD knowledge measure, and cognitive screening.

Results: Sixty of 85 eligible individuals consented. Seventy-percent of the sample self-reported as African American, Haitian Creole, or Hispanic, and 75% were female, with an average …

Cognitive And Behavioral Domains That Reliably Differentiate Normal Aging And Dementia In Down Syndrome, Jordan P. Harp, Lisa M. Koehl, Kathryn L. Van Pelt, Christy L. Hom, Eric Doran, Elizabeth Head, Ira T. Lott, Frederick A. Schmitt

Primary care integration of Down syndrome (DS)-specific dementia screening is strongly advised. The current study employed principal components analysis (PCA) and classification and regression tree (CART) analyses to identify an abbreviated battery for dementia classification. Scale- and subscale-level scores from 141 participants (no dementia n = 68; probable Alzheimer’s disease n = 73), for the Severe Impairment Battery (SIB), Dementia Scale for People with Learning Disabilities (DLD), and Vineland Adaptive Behavior Scales—Second Edition (Vineland-II) were analyzed. Two principle components (PC1, PC2) were identified with the odds of a probable dementia diagnosis increasing 2.54 times per PC1 unit increase and by …

Community-Dwelling Older Adult Fall Prevention Improvement Project, Evan Edminster Bsn, Rn, Cfrn, Tcrn, Cen, Nhdp-Bc

Abstract

Problem: Ground-level falls among community-dwelling adults 60 years and older are significant and contribute to adverse health outcomes such as fractures, functional decline, disability, and death. Additionally, falls among community-dwelling older adults are the number one mechanism of injury seen at a Northern California Level II trauma center. Falls often lead to post-fall fear, activity restriction, and physical deconditioning, further compounding fall risk.

Context: When trauma centers provide targeted outreach and screening for unmanaged health risks such as falls, they reduce unnecessary disability and premature death in the local population. Reducing total fall victim numbers and fall recidivism also …

Dysregulation Of Systemic Immunity In Aging And Dementia, Jenny Lutshumba, Barbara S. Nikolajczyk, Adam D. Bachstetter

Pharmacology and Nutritional Sciences Faculty Publications

Neuroinflammation and the tissue-resident innate immune cells, the microglia, respond and contribute to neurodegenerative pathology. Although microglia have been the focus of work linking neuroinflammation and associated dementias like Alzheimer’s Disease, the inflammatory milieu of brain is a conglomerate of cross-talk amongst microglia, systemic immune cells and soluble mediators like cytokines. Age-related changes in the inflammatory profile at the levels of both the brain and periphery are largely orchestrated by immune system cells. Strong evidence indicates that both innate and adaptive immune cells, the latter including T cells and B cells, contribute to chronic neuroinflammation and thus dementia. Neurodegenerative hallmarks …

Dystrophic Microglia Are Associated With Neurodegenerative Disease And Not Healthy Aging In The Human Brain, Ryan K. Shahidehpour, Rebecca E. Higdon, Nicole G. Crawford, Janna H. Neltner, Eseosa T. Ighodaro, Ela Patel, Douglas Price, Peter T. Nelson, Adam D. Bachstetter

Loss of physiological microglial function may increase the propagation of neurodegenerative diseases. Cellular senescence is a hallmark of aging; thus, we hypothesized age could be a cause of dystrophic microglia. Stereological counts were performed for total microglia, 2 microglia morphologies (hypertrophic and dystrophic) across the human lifespan. An age-associated increase in the number of dystrophic microglia was found in the hippocampus and frontal cortex. However, the increase in dystrophic microglia was proportional to the age-related increase in the total number of microglia. Thus, aging alone does not explain the presence of dystrophic microglia. We next tested if dystrophic microglia could …
