Progressive Cardiac Phenotypes And Reduced Reversibility From Long-Term Cugexp Rna Expression In A Dm1 Mouse Model, Rong-Chi Hu, Mohammadreza Tabary, Xander Ht Wehrens, Thomas A Cooper

Faculty, Staff and Students Publications

Myotonic dystrophy type 1 (DM1) is caused by an expanded CTG repeat in the DMPK gene, resulting in mutant transcripts that form expanded CUG (CUGexp) RNA foci and sequester muscleblind-like (MBNL) RNA-binding proteins. DM1 is multisystemic, with progressive worsening of disease manifestations in affected tissues. Disease progression is attributed to somatic expansion of the CTG repeats with age, resulting in production of CUGexp RNA with enhanced intrinsic toxicity due to increased MBNL sequestration. To determine the degree to which cardiac disease progression can occur independently of repeat expansion, we used a transgenic DM1 mouse model with inducible heart-specific expression of …

Improving Postoperative Handoff For Placenta Accreta: Implementing A Structured Handoff Communication Tool, Isabelle L. Gerrard

Doctor of Nursing Practice Final Project Abstract

Purpose Implement a standardized postoperative handoff tool to improve interdisciplinary communication during transfer of placenta accreta spectrum (PAS) patients from the operating room to an obstetric intensive care unit at an academic women's hospital.

Background Placenta accreta spectrum (PAS) is a high-risk obstetric condition requiring coordinated multidisciplinary care. At the project site, operating room (OR)-to-obstetric intensive care unit (OB ICU) handoffs lacked a standardized process. This resulted in inconsistent communication and omission of critical information. Nurses reported reduced confidence. Standardized handoff tools can improve communication and promote safer transitions of care.

Methodology This 10-week quality improvement project used Plan-Do-Study-Act methodology …

Department of Emergency Medicine Faculty Papers

BACKGROUND: Systemic inflammation is hypothesized to contribute to post-traumatic stress disorder (PTSD) vulnerability. Few studies have examined inflammation shortly after trauma as a predictor of later PTSD symptoms. We examined whether inflammation from the emergency department (ED) post-trauma is associated with PTSD symptom severity over the following 6 months.

METHODS: Our sample included 742 AURORA participants, a longitudinal cohort of patients in 29 EDs across the United States after a traumatic stressor, followed up to 6 months. Plasma cytokines were assessed from a study blood draw in the ED: an inflammatory index (standardized sum of generally pro-inflammatory markers interleukin [IL]-6, …

Modeling Individual Self-Protective Behavior During Epidemics, Geonsik Yu, Michael J. Garee, Mario Ventresca, Yuehwern Yih

Faculty Publications

Protecting public health from infectious diseases requires collective action, as individual behaviors—such as vaccination and mask-wearing—directly influence disease dynamics. During the COVID-19 pandemic, unexpected public responses often undermined the effectiveness of interventions, highlighting the need to understand collective behavioral patterns and motivations to design more effective mitigation strategies. This study presents an agent-based simulation model that captures how individuals adjust self-protective behaviors based on evolving opinions about disease risk and examines how these decisions interact with external factors, such as public health interventions, to shape collective outcomes. To improve the representativeness of the simulated population, multiple datasets were integrated to …

In this study, we developed aqueous nanoparticles (NPs) composed of a combined chemotherapeutic agent and photothermal therapy drug,[DOX][IR820], using a simple reprecipitation method. By adjusting different parameters, we tuned NP size and evaluated how this influenced their photophysical behavior, such as absorbance and fluorescence emission, and photothermal therapeutic activity such as light-to-heat conversion efficiency. These properties were analyzed to identify the optimal …

Visual And Refractive Outcomes Of Premium Intraocular Lens Implantation In Post-Refractive Eyes Undergoing Refractive Lens Exchange Or Cataract Surgery, Simon Zakhari, Abhilash Guduru

Cumberland Medica

Historically, premium intraocular lenses (IOLs) were used cautiously in post-refractive patients due to concerns that preexisting or surgically induced higher-order aberrations could degrade visual quality by increasing glare and halos, while also reducing contrast sensitivity. Patients with prior corneal refractive procedures (LASIK, PRK, SMILE, or RK) often have altered corneal curvature, making IOL power calculations and lens performance less predictable. With advances in biometry, corneal imaging, and modern IOL designs that compensate for spherical aberrations, these concerns have diminished. This retrospective cross-sectional study evaluated visual and patient satisfaction outcomes after premium IOL implantation in post-refractive eyes undergoing refractive lens exchange …

Reducing Emergency Department Overuse Through Patient Education, Maddie Pieper, Joshua Heuertz

Doctor of Nursing Practice Projects: College of Nursing

Background/Introduction

Emergency departments (EDs) are designed to provide rapid evaluation and management of acute, life-threatening, and time-sensitive conditions. However, EDs are frequently used for nonemergent or low-acuity concerns that could be managed in primary care or urgent care settings. This overuse contributes to rising healthcare costs, resource strain, longer wait times, and overcrowding. Underserved populations may rely more heavily on ED services because of barriers such as limited primary care access, language differences, low health literacy, restrictive work schedules, transportation challenges, and difficulty navigating the healthcare system. These factors can make the ED seem the most accessible source of care. …

Colorectal Cancer Screening: Implementation And Evaluation Of A Screening Algorithm In A Rural Family Practice Clinic, Mollie M. Tate, Whitney Dubas

Doctor of Nursing Practice Projects: College of Nursing

Background: Colorectal cancer (CRC) is the second leading cause of cancer-related mortality in the United States and disproportionately affects rural populations. Although more than 90% of cases occur in adults older than 50 years, increasing incidence among younger adults prompted an update to national guidelines recommending screening beginning at age 45. Rural residents face multiple barriers to colorectal cancer screening (CRCS), including limited access to care, transportation challenges, lack of insurance, and absence of standardized screening processes in primary care. These barriers contribute to lower screening rates, delayed diagnosis, and poorer outcomes. Evidence demonstrates that CRCS reduces CRC morbidity and …

Transition To Noninvasive Testing From The Gold Standard Of Liver Biopsy, Heidi Bien, Sabina Choudhry, Christine Pocha, University Of South Dakota Sanford School Of Medicine & Avera Health System

Scholarship Pathways Program

Purpose: Metabolic dysfunction–associated steatotic liver disease (MASLD), formerly known as non-alcoholic fatty liver disease, represents a rapidly growing public health concern, affecting roughly 30% of the global population. MASLD encompasses a spectrum from simple steatosis to its more progressive form, metabolic dysfunction–associated steatohepatitis (MASH). Early and accurate assessment of liver disease is critical for risk stratification and management, yet the current gold standard-liver biopsy remains invasive, costly, and limited by sampling variability and interpretive subjectivity. Noninvasive imaging modalities, particularly magnetic resonance elastography (MRE), have emerged as promising alternatives, but their concordance with biopsy in real-world clinical practice remains underexplored.

Impact of Dermatology Access on Dermatofibrosarcoma Protuberans Outcomes

Joseph H. Kelly MD

Mentor: Marcus L. Frohm, MD

Introduction: Dermatofibrosarcoma protuberans is a locally aggressive rare dermal sarcoma with a relatively high rate of local recurrence. Incidence in the United States has been reported around 4 occurrences per million people per year, and recurrence rates have been reported between 2 to 19%. Recurrence poses a higher risk for sarcomatous transformation, increasing the risk for metastasis. Early and accurate diagnosis, coupled with appropriate management, is essential to minimize these risks. This study extended previous research by evaluating whether access to dermatology care …
