Unsuitable Underlying Cause-Of-Death Statements: Implementation And Evaluation Of A Structured Process For Healthcare Providers Certifying Natural Causes Of Death In An Outpatient Setting, Naida Rutherford

Doctor of Nursing Practice Projects

Background: Accuracy in death certification is crucial for effective public health initiatives. Inaccuracies in unsuitable Underlying Cause-of-Death (UCOD) statements can distort mortality statistics, influence health policy, and impact resource allocation. In South Carolina, changes in the death registration process and the introduction of an unsuitable cause-of-death list highlighted an urgent need for structured training among certifiers to enhance accuracy in death documentation.

Purpose: The purpose of this project was to implement a standardized training program for healthcare providers certifying natural causes of death and assessing the impact of reducing the unsuitable underlying cause-of-death inaccuracies in an outpatient hospice setting.

Increasing Colorectal Cancer Screening Rates For Patients Without Insurance, Andrea F. Day

Doctor of Nursing Practice Projects

Background: Colorectal cancer is a leading cause of cancer-related death in the United States (U.S.), ranking as second most prevalent overall. Despite many initiatives, screening rates remain low, especially among clinic patients without insurance. The lack of an evidence-based screening protocol exacerbates these issues and increases the risk of advanced cancer and death. Initial data showed that 0% of patients were screened according to recommended guidelines.

Purpose: The project implemented a standard screening protocol to increase colorectal cancer screening rates in a rural Alabama free clinic for patients ages 45-64 lacking insurance.

Smelling is a human sense, expressing strong sexual dimorphisms. We aim to improve the knowledge of the genetics of human olfactory perception by performing an exploratory genome-wide association meta-analysis of up to 21,495 individuals of European ancestry. By sex-stratified and overall analysis of the identification of twelve odours and an identification score, we discovered ten independent loci, seven of them novel, with trait-wise genome-wide significance (p <  5 × 10−8) involving five odours. Seven of these loci, including four novel ones, are also significant using a stricter study-wide significance threshold (p <  3.85 × 10−9). Loci were predominantly located within clusters of olfactory receptors. Two loci were female-specific while one was sex-differential with respective candidate genes containing androgen response elements. Two-sample Mendelian randomization was applied to search for causal relationships between sex hormones, odour identification and neurodegenerative diseases. A causal negative effect was detected for Alzheimer’s disease on the identification score. These findings deepen our understanding of the genetic basis of olfactory perception and its interaction with sex, prioritizing mechanisms for further molecular research.

Investigating Environmental And Socioeconomic Contributors To Adult Obesity In The Rio Grande Valley, John Nicholas Cauba, Jihoo Woo, Russel Wiggins, Shizue Mito

School of Medicine Publications

Obesity in the Rio Grande Valley (RGV) of Texas remains a critical public health concern, with rates (46.9%) significantly exceeding those of Texas (36%) and the U.S. (34%) (p < 0.001). This study used 2024 County Health Rankings data to analyze environmental and socioeconomic contributors to obesity across 240 Texas counties, with a population-weighted focus on Hidalgo, Cameron, Starr, and Willacy counties. The RGV exhibited markedly poorer access to exercise, higher rates of physical inactivity, lower Food Environment Index scores (FEI = 4.3 vs. 5.7 in Texas), higher rates of uninsurance, worse patient-to–primary care physician (PCP) ratios (2152:1 vs. Texas 1660:1), and increased preventable hospitalizations. Multiple linear regression identified physical inactivity (β = 0.6, p = 0.01) and access to exercise (β = −0.02, p = 0.02) as significant predictors of obesity. Notably, higher uninsured rates were associated with lower reported obesity, likely due to underdiagnosis in the absence of routine care. These findings emphasize the need for targeted interventions addressing food access, environmental and recreational infrastructure, along with healthcare infrastructure in the RGV, where socioeconomic disadvantage and structural barriers magnify the impact of national obesity trends on the regional level.

Microbial Biosensor For Sensing And Treatment Of Intestinal Inflammation, Duolong Zhu, Jeffrey Galley, Jason Pizzini, Elena Musteata, Martin V Douglas, Walter J Chazin, Eric P Skaar, Jeffrey J Tabor, Robert A Britton

Faculty, Staff and Students Publications

Synthetic biology has enabled the development of biosensors to detect intestinal inflammation, yet few target the clinically validated biomarker of intestinal inflammation calprotectin with both diagnostic and therapeutic capabilities. Here, an optimized calprotectin biosensor is presented that leverages a zinc uptake regulator (Zur) controlled promoter coupled with a memory circuit to detect and record intestinal inflammation in vivo. The level of biosensor activation strongly correlates with calprotectin levels in the colon of two independent mouse models of colitis. Coupling of the biosensor with the production of the anti-inflammatory cytokine IL10 allowed for the resolution of chemically induced colitis, demonstrating the …

Hypoxia-inducible factors (HIFs) promote lung protection and pathogen eradication during acute lung injury. We therefore tested the theory that pharmacologic stabilization of HIFs dampens lung injury during SARS-CoV-2 pneumonia. Initial studies in murine SARS-CoV-2 models showed improved outcomes after treatment with the FDA-approved HIF-stabilizer vadadustat. Subsequent studies in genetic models implicated alveolar-expressed Hif1a in mediating lung protection. Therefore, we performed a randomized, double-blinded, multicenter phase 2 trial in patients admitted for SARS-CoV-2 infection and concomitant hypoxia (SpO2 ≤ 94%). Patients (n=448) were randomized to oral vadadustat (900 mg/day) or placebo for up to 14 days. Safety events were similar between …

Regulation Of Myogenesis By Mechanomir-200c/Foxo3 Axis, Junaith S Mohamed, Aladin M Boriek

Faculty, Staff and Students Publications

Cyclic mechanical stretch has been shown to inhibit myoblast differentiation while promoting proliferation. However, the underlying molecular mechanisms are not well understood. Here, we report that mechanical stretch inhibits the differentiation of mouse primary myoblasts by promoting the cell cycle program and by inhibiting the expression of the myogenic regulator MyoD. Stretch alters the miRNA expression profile as evidenced by miRNA microarray analysis. We identified miR-200c as one of the highly downregulated mechanosensitive miRNAs (mechanomiRs) whose expression level was increased during differentiation. This suggests that mechanomiRs-200c is a myogenic miRNA. Overexpression of mechanomiR-200c revoked the effect of stretch on myoblast …
