Faculty, Staff and Student Publications

Background: AI-generated content is being used across the education spectrum and is beneficial for creating complex multiple-choice questions, such as those used in medical education. However, evaluating AI-generated content is challenging, and existing testing and evaluation methods are falling short. This study uses randomization to compare medical students' performance on and subjective evaluation of AI versus expert-generated questions. We hypothesized that there would be no difference in student performance or subjective evaluation of AI vs expert-generated questions.

Methods: We designed a single-center, randomized study where medical student participants received either one AI- or expert-generated question per day over four weeks. …

Limosilactobacillus Reuteri Promotes Melatonin Release From Human Intestinal Organoids Via 5′Ectonucleotidase Activity, Micah D Forshee, Erika J Nachman, Esha R Shenoy, Heather A Danhof, Ludwig Ermann Lundberg, Stefan Roos, Robert A Britton

Faculty, Staff and Students Publications

Strains of Limosilactobacillus reuteri have been used to prevent or treat various conditions; however, the mechanisms by which they exert beneficial effects are not completely understood. Infant colic is one example in which L. reuteri DSM 17938 reduces clinical symptoms. While the etiology of colic is unknown, abnormal melatonin levels in infants have been suggested as a possible contributor. L. reuteri DSM 17938 has been shown to produce adenosine from AMP via production of the extracellular enzyme 5′ectonucleotidase (5′NT). Adenosine is a potent signaling molecule that impacts several important aspects of host physiology, including the release of melatonin from the …

When Probiotics Guidelines Differ: A Practical Guide For Clinicians And Researchers, Geoffrey A Preidis, Hania Szajewska, Marla Cunningham, Howard Bauchner, Daniel J Merenstein

Faculty, Staff and Students Publications

Many professional organizations publish clinical practice guidelines for the use of probiotics in gastrointestinal disorders. Generally, no two guidelines align perfectly, and some differ markedly. These discrepancies occur because clinical practice guidelines are not purely mechanical outputs of data synthesis. They are shaped by structured interpretation, value judgments, and predefined thresholds for uncertainty. These elements become particularly visible when effect sizes are small, heterogeneity is high, and outcomes vary in clinical relevance-as is the case with probiotic research. This article examines why discordance among probiotic guidelines is predictable and provides practical guidance for clinicians who must decide among conflicting recommendations …

Steroid Receptor Coactivator 3-Deficient Regulatory T Cells Eradicate Multiple Solid Tumors In Syngeneic Mouse Models, Nuri Sung, Eunsu Kim, Yosef Gilad, Yuri Park, Adam M Dean, Yan Xia, Jianming Xu, Clifford C Dacso, David M Lonard, Sang Jun Han

Faculty, Staff and Students Publications

Steroid receptor coactivator 3 (SRC-3) is highly expressed in regulatory T cells (Tregs) and is important for their immunosuppressive activity. Recently, we demonstrated that disrupting SRC-3 expression in Tregs eliminates triple-negative breast cancer (TNBC) and prostate cancer in syngeneic animal models by generating an anti-tumor immune microenvironment without inducing immune-related adverse events (irAEs). Further analysis of these mice revealed that SRC-3 knockout (KO) Tregs infiltrated breast tumors and facilitated the infiltration of CD8

Reducing Acute Healthcare Services With Self-Management Of Blood Pressure Monitoring Through Remote Patient Monitoring For Hypertensive Patients A Quality Improvement Project, Becky J. Wagner

Doctor of Nursing Practice (DNP) Manuscripts

Hypertension (HTN) affects nearly half of U.S. adults and remains a leading cause of preventable emergency department (ED) visits, hospitalizations, and healthcare costs due to poor blood pressure (BP) control (Fryar et al., 2024; Mullins et al., 2019). Traditional care models often lack the continuous monitoring and timely intervention needed for effective chronic disease management. Remote Patient Monitoring (RPM) provides an innovative approach by delivering real-time BP data, enabling early clinical intervention, and encouraging patient engagement in self-management (Omboni et al., 2020).

This Doctor of Nursing Practice (DNP) project evaluated the effectiveness of an RPM intervention in reducing acute healthcare …

Impact Of Implementing Standard Wound Care Guidelines For Patients In The Home Care Setting On Patient Outcomes, Raymond Anthony Flores Jr

Doctor of Nursing Practice (DNP) Projects

Wound care is among the most significant public health concerns, affecting millions of people worldwide. Most individuals with wounds end up self-managing their condition from their homes due to being discharged early from the hospital, owing to various reasons, and the costs associated with health care. Although home wound management offers convenience and lower costs for patients, it is also associated with substantial challenges, including limited access to and use of appropriate care protocols, wound management tools, and sufficient education on the topic, as well as limited professional advice. These limitations contribute to poor outcomes, including slow healing rates, infections, …

Robust Statistical Methods For Microbiome Abundance Data, Yiming Shi

WUSM Theses and Dissertations – All Programs

Differential abundance analysis in microbiome studies aims to identify taxa whose abundance differs across biological or clinical conditions. The observed data are typically taxon-specific sequencing read counts, representing reads assigned to different taxa within each sample. These counts are indirect measurements of the underlying microbial abundance profile and are constrained by sample-specific library sizes. Microbiome count data are also typically sparse, overdispersed, and heteroscedastic. Together, these characteristics create substantial challenges for differential abundance analysis and make the results highly sensitive to normalization procedures, model specification, and the statistical methods used for inference.

Normalization defines the scale on which samples are …

Investigating The Ability Of Presequences To Influence Mitochondrial Protein Import, Youmian Yan

WUSM Theses and Dissertations – All Programs

Mitochondria are essential organelles housing over 1000 proteins, 99% of which are nuclear-encoded and synthesized in the cytosol. Most mitochondrial proteins are targeted by a positively charged sequence called the presequence, which lacks a common sequence motif and is poorly conserved across evolution. Accumulating evidence suggests that presequences encode meaningful information that influences mitochondrial protein uptake. For instance, multiple stress response models propose that stress sensing proteins contain “weak” presequences which allows them to monitor mitochondrial health. However, there is a lack of systematic examination about how presequences influence import kinetics and what constitutes presequence strength. These gaps in knowledge …

Revisiting Ulam Stability For Boundary Value Problems, Martin Bohner, Snezhana Hristova, Agnieszka B. Malinowska, Ewa Girejko

Mathematics and Statistics Faculty Research & Creative Works

The main goal of this paper is to apply Ulam stability theory to boundary value problems for dynamic equations, while addressing several common misconceptions found in the existing literature. We identify the key issues that arise when applying Ulam stability to such problems and propose three distinct approaches to overcome them. To enhance clarity and accessibility, we begin with nonlinear ordinary differential equations and subsequently extend the analysis to nonlinear dynamic equations on time scales. Since a time scale is defined as any nonempty closed subset of the real numbers, our results are applicable to dynamic equations on continuous, discrete, …

Implementing Updated Npo Guidelines For Inpatient Procedures, Yasamin Ghanivand

Doctor of Nursing Practice (DNP) Projects

Background: Nil per os (NPO) guidelines are utilized for patient safety during procedures to reduce the risk of pulmonary aspiration. The American Society of Anesthesiologists (ASA) recommends clear liquids up to 2 hours before non-emergent procedures, although many facilities still implement the outdated practice of ordering NPO after midnight. This practice can lead to prolonged fasting, which may cause increased hunger, thirst, hypotension, nausea, and dizziness, ultimately resulting in patient dissatisfaction and discomfort.

Purpose: To review and assess current ASA NPO guidelines that describe best practice to enhance the patient experience without increasing perioperative risk of pulmonary aspiration.

Methods: A …

Weathering The Divide: Social Determinants, Neighborhood Context, And Systemic Lupus Erythematosus Among African American Women, Vanessa Cl Morman

Electronic Theses and Dissertations

Background: Systemic lupus erythematosus (SLE) disproportionately affects African American women and contributes to racial health disparities in the United States. Although genetic susceptibility influences disease risk, growing evidence suggests that social determinants of health (SDOH), including neighborhood conditions, structural racism, and socioeconomic disadvantage, contribute to disease development and progression. Epigenetic mechanisms may provide a biological pathway linking adverse social conditions to chronic disease disparities. This dissertation examined the influence of SDOH on SLE disparities through evidence synthesis and empirical investigation to inform public health practice and policy.

Methods: This integrated learning experience consisted of three complementary manuscripts. Aim 1 was …
