Faculty, Staff and Student Publications

The spread of tau pathology across the cerebral cortex is closely tied to cognitive decline in Alzheimer's disease (AD). To investigate mechanisms underlying tau spread, we measured bioactivity of tau seeds from inferior temporal gyrus (ITG) and superior frontal gyrus (SFG) synaptosomes in 128 individuals and demonstrated that tau seed bioactivity associates with tau phosphorylation, neurofibrillary tangles (NFTs), and cognitive impairment. Incorporating genotype data from the same individuals within a Mendelian randomization framework showed that tau seeds in ITG induce NFTs locally as well as drive tau seeds and NFTs in SFG. Integrating antemortem functional magnetic resonance imaging data from …

Nurse Staffing Variation Viewed Through The Lens Of Institutional Isomorphism, Mara Raggi Jul 2026

Nurse Staffing Variation Viewed Through The Lens Of Institutional Isomorphism, Mara Raggi

Electronic Theses and Dissertations

Nurse staffing is strongly associated with organizational and patient quality outcomes. Existing studies have not adequately explained why nurse staffing levels vary across hospitals operating under similar external institutional isomorphic pressures. Secondary and administrative datasets, along with random-effects regression models, were used to analyze 6 years of data (2014-2019) and examine the relationship between institutional factors and hospital nurse staffing in the general acute care setting. The results indicate that coercive factors of state laws were significantly associated with nurse staffing. Staffing mandates and staffing committees were significantly associated with increases in nurse staffing, while public reporting was significantly associated …

High Burden Of Elevated Fib-4 In Metabolically At-Risk Primary Care Patients: Simple Predictors To Guide Hepatic Fibrosis Triage, Ridwan Ademola Lawal, Fatimah Bello, Rashmee Patil, Juliana Yang

Research Symposium

Background: Metabolic dysfunction–associated steatotic liver disease (MASLD), including metabolic dysfunction–associated steatohepatitis (MASH), is a leading cause of chronic liver disease worldwide. Current guidelines recommend fibrosis-based risk stratification using noninvasive tools such as the Fibrosis-4 (FIB-4) index in patients with metabolic risk factors, followed by secondary assessment (e.g., transient elastography or enhanced liver fibrosis(ELF) testing) for those with elevated scores. However, data on the real-world prevalence of elevated FIB-4 in U.S. primary care populations, particularly in safety-net settings, and the downstream implications for fibrosis evaluation remain limited. We aimed to quantify the burden of elevated FIB-4 in a primary care setting …

The vaginal microbiome is often interpreted through static taxonomic patterns. Yet microbial composition alone does not explain why some communities resist perturbation, recover after disruption, or transition toward dysbiosis. This narrative review synthesizes evidence that vaginal microbiome stability is shaped by endocrine phase, epithelial substrate availability, microbial functional capacity, mucosal tone and candidate host modifiers. High-estrogen states, particularly pregnancy, are associated with epithelial maturation, glycogen accumulation, low vaginal pH, and Lactobacillus-dominant communities, whereas postpartum, lactational, menopausal, and other hypoestrogenic states are associated with reduced epithelial support and increased vulnerability to diverse anaerobe-rich configurations. We review the linking of the estrogen–glycogen–Lactobacillus …
