Access To Healthcare For Rural Transgender Adults In The United States, Devon Smith

University Honors Theses

Urban and rural healthcare differ significantly in the amount of facilities, providers and kinds of specialty care that are offered in each environment. The United States is split into urban and rural counties in any given region, and based on those population sizes, are the allocation of healthcare resources for residents. In rural areas in the U.S., transgender adults lack access to gender-affirming care and encounter a lack of gender-affirming care providers due to workforce shortages, discrimination, and a lack of cultural competency. To determine if these residents lacked access to care compared with their urban counterparts, I performed a …

Awareness, Knowledge, And Motivations About Lifespan, Healthspan, And Healthy Longevity Medicine In The General Population: The Healthy Longevity (Helo) Conceptual Framework, Belinda Wang, Anna Szucs, Elena Sandalova, E. J. Horberg, Paul A. O'Keefe, Louis Island, Hans J. Meij, Sonny Rosenthal, Andrea B. Maier

Research Collection College of Integrative Studies

The global population is ageing and the gap between lifespan (total years lived) and healthspan (years lived free of diseases) is increasing. Healthy Longevity Medicine (HLM) is an approach to optimise health and healthspan, and it has substantial public health implications. Despite those implications, the understanding of public perspectives on this field is lacking. The HEalthy LOngevity (HELO) framework was developed through a literature review guided by expert discussions across disciplines to include evidence-based concepts of health-related decision-making, ageing, and HLM. The framework organises concepts into three components. The first two components, awareness and knowledge, explore public perception and understanding …

Centre of Excellence in Women and Child Health

Storytelling is increasingly recognized as a powerful tool in public health communication, particularly for addressing complex and stigmatized health issues. In the context of pregnancy and childbirth, personal narratives have proven effective in shaping perceptions, empowering women, complementing health education, and driving policy and legal reforms. Preterm birth remains a significant global challenge, and lived experiences of affected families offer critical insights that illuminate systemic gaps and advocate for the rights of babies, mothers, families, and healthcare workers. The Born Too Soon 2023 campaign placed people—especially women, families, communities, and healthcare workers—at the core of its advocacy efforts. This commentary …

A Sumo-Interacting Motif In The Guanine Nucleotide Exchange Factor Epac1 Is Required For Subcellular Targeting And Function, Wenli Yang, Fang Mei, Wei Lin, Jason E Lee, Si Nie, Christopher J Bley, André Hoelz, Xiaodong Cheng

The Brown Foundation: Institute of Molecular Medicine

Exchange protein directly activated by cAMP (EPAC1), a multifunctional intracellular cAMP receptor, dynamically localizes to various cellular loci, engaging with diverse molecular partners to maintain cellular homeostasis. The study investigates the role of the SUMO-interacting motif (SIM) in the subcellular targeting and cellular functions of EPAC1. It reveals that the SIM is a critical structural element for EPAC1's association with RanBP2/nucleoporin 358, a nucleoporin of the cytoplasmic filament component of the nuclear pore complex. Mutational disruption of EPAC1 SIM interferes with EPAC1's ability to activate its canonical effectors, small GTPases, Rap1 and Rap2, and noncanonical functions, such as the formation …

Allergic fungal rhinosinusitis (AFRS) is a unique endotype of chronic rhinosinusitis with nasal polyps (CRSwNP). Despite high recurrence rates and often more severe presenting signs compared with other subtypes of CRSwNP, research dedicated to AFRS has been lacking. Diagnostic criteria are outdated, the mechanistic relationship of AFRS to other associated diseases is unclear, and the pathophysiology of disease and risk factors for recurrence have not been well studied. In December 2023, a multidisciplinary group of rhinologists, otolaryngologists, pulmonologists, allergists, immunologists, scientists, and infectious disease experts met at the National Institute of Health to discuss unmet needs for future AFRS research …

Identification And Functional Assessment Of Candidate Causal Cis-Regulatory Variants Underlying Electrocardiographic Qt Interval Gwas Loci, Supraja Kadagandla, Lavanya Gunamalai, Dongwon Lee, Ashish Kapoor

The Brown Foundation: Institute of Molecular Medicine

Background: Identifying causal variants among tens or hundreds of associated variants at each locus in genome-wide association studies is challenging. As the vast majority of genome-wide association studies variants are noncoding, sequence variation at cis-regulatory elements (CREs) affecting transcriptional expression of specific genes is a widely accepted molecular hypothesis. Following this hypothesis, combined with the observation that open chromatin is a universal hallmark of all types of CREs, we aimed to identify candidate causal cis-regulatory variants underlying QT interval genome-wide association studies loci.

Methods: Common variants in high linkage disequilibrium with genome-wide significant variants were identified using variant …

Monte Carlo Study Of Gold Nanoparticle-Mediated Radiosensitization Effects Using Nanoscale Cell Model Combined With Fractal-Based Dna Model, Amrit Kaphle, Sandun Jayarathna, Sunil Krishnan, Sang Hyun Cho

The Brown Foundation: Institute of Molecular Medicine

Background: Gold nanoparticles (GNPs) are promising radiosensitizers in radiation therapy, yet the exact mechanisms behind their effectiveness remain not fully understood. Monte Carlo (MC) simulations have been used to study extra energy deposition and increased DNA damage by the secondary electrons from intracellularly present GNPs, which are believed to be the key physical mechanisms responsible for the radiosensitization effects observed in many radiobiological studies. However, discrepancies between experimental results and computational predictions persist. While often attributed to purely biological effects, such discrepancies, from a physical modeling point of view, can also be due to the use of MC models constructed …

Utility Of Readily Available Sugammadex For Emergent Neuromuscular Blockade Reversal., Theodore Renner, Kevin Varner, Austin Shaffer, Elizabeth Johnson-Gray, Noah Le, Matthias Franzen

Surgery Articles

INTRODUCTION: Anesthesia providers are often called upon to assist with other providers during can't intubate, can't ventilate (CICV) scenarios. The current availability of doses of sugammadex sufficient to provide emergent reversal of neuromuscular blockade in an operating room environment requires visits to multiple operating rooms at our institution. The Anesthesiology Department at OhioHealth Doctors Hospital sought to evaluate the practicality of administering a rescue dose of sugammadex (16 mg/kg) in a CICV scenario. The current storage of sugammadex is six 200 mg vials maximum per operating room, which would provide insufficient dosing for emergent reversal dosing for most adult patients. …

Faculty, Staff and Student Publications

Objectives: We investigated whether self-reported vision and hearing were associated with cognitive function and loneliness among Mexican adults aged 50 and older.

Methods: Mexican Health and Aging Study data. Vision/hearing status was self-reported (excellent-very good, good, fair-poor). Cognition was measured using nine tasks. Loneliness was measured using the UCLA Loneliness Scale. Analyses controlled for demographic and health characteristics.

Results: Among 12,353 participants (mean age = 67, 58% female), poor vision, but not hearing, was associated with lower global cognition (β = -0.03, p < .05). Poor vision (OR = 1.57, 95% CI = 1.30-1.91) and hearing (OR = 1.35, 95% CI = 1.14-1.61) were associated with higher odds of being lonely after adjusting for demographics and comorbidities, but not when adjusting for limitations in daily activities and depressive symptoms.

Discussion: Poor vision is a potentially modifiable risk factor for lower cognition and loneliness among Mexican adults. …
