Identifying Modulators Of Stable Klrg1+Il7ra+ Memory Cd8+ T-Cells, Christina Ocampo Valdez

Honors Projects

Type 1 diabetes (T1D) is an autoimmune disease targeting the insulin-producing beta cells of the pancreas. The discovery of insulin revolutionized the treatment of T1D, but current research into T1D has progressed from disease management to possible prevention or delayed onset of diagnosis. One drug currently in use is teplizumab, an anti-CD3 monoclonal antibody that has been shown to delay the onset of T1D in some, but not all, at-risk individuals. High levels of a subset of peripheral blood CD8+ T cells we call SKIMs (stable KLRG1+ IL7Ra+ memory cells), which include MAIT (mucosal-associated invariant T) cells, have been associated …

Malnutrition At The Time Of Surgery Predicts Increased Morbidity After Distal Femur Fracture Fixation: A Propensity-Matched Analysis, Jawad Saad, Amir Ghafarian, Tyler Forbes, Muaaz Wajath, Noor Saad, Khaled Saleh

Medical Student Research Symposium

Abstract

Background: Distal femur fractures (DFF) are serious injuries most often affecting older adults with multiple medical comorbidities. Malnutrition is known to worsen outcomes in elective orthopedic surgery, but its impact in urgent DFF fixation, where optimization time is limited, remains unclear. This study evaluated whether preoperative malnutrition predicts 90-day morbidity after DFF fixation and whether implant choice influences risk among malnourished patients.

Methods: Adults undergoing operative DFF fixation from 2005–2025 were identified using the TriNetX U.S. Collaborative Network. Malnutrition was defined as serum albumin ≤3.5 g/dL or leukocyte count ≤1.5×10³/µL within one year preoperatively. After 1:1 propensity matching for …

Title: Impact of Dietician Counseling on Outcomes in Newly Diagnosed Celiac Disease

Background: Dietician counseling is routinely recommended for newly diagnosed celiac disease (CD), yet its measurable impact is not well defined. This study examined whether early dietician involvement improves clinical symptoms or serologic outcomes.

Methods: We retrospectively reviewed adults with biopsy-confirmed CD at a single center from 2020–2024. Demographics, symptoms, and laboratory data were collected by chart review with ≥6 months of follow-up. Patients who met with a dietician formed the dietician group; all others were assigned to the non-dietician group. Fisher's Exact tests evaluated abdominal …

Objective Oculomotor, Vestibular, Reaction Time, And Cognitive Signatures Of Vestibular Migraine, Claire E. J. Ceriani, Alexandr Braverman, Alexander Kiderman

Department of Neurology Faculty Papers

OBJECTIVE: To evaluate oculomotor, vestibular, reaction time, and cognitive (OVRT-C) function in patients with vestibular migraine (VM) using objective eye-tracking-based metrics and to identify patterns of dysfunction relative to healthy controls.

BACKGROUND: Vestibular migraine is a common yet underdiagnosed cause of vertigo. Diagnosis remains primarily clinical, because objective neurologic and vestibular findings are often absent or inconsistent. Quantitative methods capable of capturing the multisystem manifestations of VM may improve objective characterization of the disorder.

METHODS: Participants with a clinical diagnosis of vestibular migraine were recruited from a tertiary headache center and assessed using a battery of OVRT-C tests administered with …

Global Health Financing Of Diagonal Interventions: Building Resilient And Sustainable Health Systems In Sub-Saharan Africa, Lucy Kim

Master in Public Policy Theses

Background: Global health financing has historically prioritized disease-specific “vertical” programs over broader “horizontal” strengthening of general health systems. Vertical programs in HIV have led to unprecedented reductions in mortality worldwide, but HIV remains a significant public health threat in sub-Saharan Africa, where vertical strategies have long been criticized for creating fragmented health systems. In response, global health strategies have shifted towards combining vertical investments with broader horizontal activities, commonly referred to as “diagonal” programming. While evidence suggests that diagonal programming has the potential to create more resilient and sustainable health systems, evaluating its value for money is challenging due to …

Rhythms Of Hippocampal Function And Memory After Moderate Prenatal Alcohol Exposure, Lilliana May Sanchez

Psychology ETDs

Fetal Alcohol Spectrum Disorders involve morphologic and neurobiological abnormalities in offspring subjected to prenatal alcohol exposure. Although not as well studied as high exposure, moderate prenatal alcohol exposure represents the most common and undetected form in humans. While learning and memory deficits have been well characterized at the behavioral level in humans with Fetal Alcohol Spectrum Disorders and in animal models of moderate prenatal alcohol exposure, few studies have determined the circuit or systems level mechanisms of the behavioral deficits. A complete understanding of the neural bases of memory deficits after moderate prenatal alcohol exposure is needed to ultimately identify …

Exploring Health Insurance’S Role In Chronic Disease Management Among Hispanics, Romelyn Dones

Seton Hall University Dissertations and Theses (ETDs)

This qualitative study examined how insured non-English- and English-speaking Hispanic adults perceive the role of health insurance in the management of chronic disease. Chronic conditions remain a leading cause of morbidity in the United States, and although prior research suggests that insurance coverage improves access to care, it does not always enhance how individuals understand or utilize support for chronic disease management. Limited research has explored how individuals with chronic conditions interpret the role of insurance in their daily self-management practices, particularly among Hispanic populations. Guided by Andersen’s Behavioral Model of Health Services Use, this study explored how contextual, enabling, …

Early Detection Of Alzheimer's Disease And Related Dementias From Spontaneous Speech Using Foundation Speech And Language Models: Comparative Evaluation, Jingyu Li, Lingchao Mao, Xi Mao, Hairong Wang, Zhendong Wang, Xuelei Sherry Ni

School of Economics and Finance Faculty Publications

Background: Alzheimer's disease and related dementias (ADRD) are progressive neurodegenerative conditions where early detection is critical for timely intervention and care planning. However, current diagnostic methods are often inaccessible, costly, and delayed, especially for underserved populations. There is a growing need for scalable, noninvasive tools that can support timely diagnosis. Spontaneous speech contains rich acoustic and linguistic markers that can serve as noninvasive behavioral markers for cognitive decline. Foundation models, pretrained on large-scale audio or text data, generate high-dimensional embeddings that encode rich contextual and acoustic information.

Objective: This study benchmarks open-source foundation language and speech models to evaluate their …

Wills Eye Hospital Papers

We aimed to statefully validate Retinopathy of Prematurity (ROP) grading by evaluating intergrader variability over age-matched simulated exams. In a prospective retinal photographic grading cohort study, both eyes of twenty patients with five images per eye per visit were graded by twelve expert graders across six weekly visits. For each eye visit, ROP experts graded the Zone, Stage, and Plus, from which the Telemedicine ROP Severity Score (tROP-SS) was calculated. Graders retained knowledge of prior assessments for a given eye and followed International Classification of ROP rules. Intergrader coefficient of variation (CoV) for Zone, Stage, Plus, and tROP-SS remained below …

Developing Antibodies Against Galectin-3 And Galectin-9 To Target Endometriosis, Ashleigh Burger, Noah Farnsworth, Jared J. Reisnouer, Cheyenne Vue

2026 Symposium

Endometriosis is a disease characterized by pelvic pain and the formation of endometrial-like tissue on the outside of the uterine lining. This condition affects nearly 10% of women across the globe and confirming whether someone has endometriosis requires visualization in surgery. While the specific causes of this disease remain unclear, the over-expression of the Galectins 3 and 9 in ectopic endometrial tissues suggests a role in the development and maintenance of the condition. Monoclonal antibodies (mAbs) are highly specific proteins with potential as diagnostic or treatment tools. The goal of this study is to generate antibodies against Gal3 and Gal9. …

Lungs And Beyond: Seizures As Presenting Symptom In A Patient With Mycobacterium Chimaera Infection, Samar Mehyar, Tripti Adhikari, Shweta Kambali, Harneet K. Ghumman, Avneet K. Ghumman, Parul Sud, Mehrshad Fathian Sabet, Elizabeth Mikhail, Sohrab Singh

Journal of Community Hospital Internal Medicine Perspectives

Mycobacterium chimaera is a slow-growing, non-tuberculous mycobacterium (NTM) that belongs to the Mycobacterium avium complex (MAC). It first emerged as a pathogen after being associated with infections in patients who underwent cardiothoracic surgery when patients were getting exposed to heater cooler units, especially those requiring extracorporeal membrane oxygenation (ECMO) or prosthetic valve placement. We report an atypical presentation of M. chimaera infection in a patient with COPD, but no prior history of cardiac surgery or immunosuppression.

Periodontal Disease In A Classic Maya Population From Ambergris Caye, Belize: A Cej-Ac Analysis, Avery R. Mcneil

Honors Theses

Dental remains provide a durable and information-rich record of biological, dietary, and health-related processes in past populations. This study examines periodontal disease, dental wear, and morphometric variation in a Classic period Maya population from coastal Belize (ca. A.D. 700-900) using cementoenamel junction-alveolar crest (CEJ-AC) distance as one measure of periodontal health. Dental remains were assessed using standardized bioarchaeological methods, including tooth identification, crown measurements, and periodontal scoring based on mean CEJ-AC distances recorded at preserved surfaces. The results indicate widespread mild to moderate periodontal disease across the sample, with posterior teeth exhibiting greater alveolar bone loss than anterior dentition. These …

Quantifying Black Carbon Concentrations in Georgia and Analyzing Associated Public Health Risks

One of the most daunting challenges of the industrial world is air pollution. Within this broad spectrum, there is an inhalable particle group named PM2.5, which contains black carbon. Black carbon has evidence that supports the generation and worsening of adverse health impacts, which may include birth complications, cognitive deficits in children, pulmonary aggravation, asthma, cardiovascular issues, neurological degenerative patterns, and cancer risk. This is especially seen in vulnerable populations, like children, elderly, and those who already suffer from weakened health, many of which reside in the southern …

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 …

Head Acceleration Events in Collegiate Rodeo Athletes

Colton Carlson, MS4

Mentor: Thayne Munce, PhD

Introduction: Brain health has been a growing concern across a wide range of contact sports in the last three decades. While most of the early brain health research was focused on identifying and preventing concussions, newer research has found that an accumulation of repetitive head impacts (RHI) is more predictive of long-term brain health than the number of concussions sustained. Consequently, being able to assess RHI in sports despite the lack of outward symptoms has become paramount in promoting the long-term health of athletes. While the …

Addressing Vaccine Hesitancy with Patient Education

Belle Grady, MD | Mentor: Victor Huber, PhD

Background: Vaccine hesitancy is a complex global issue, exacerbated by pandemics and social media. In addition to hesitancy, state policies loosening childhood vaccine requirements and alternative vaccination schedules may contribute to recent vaccine-preventable illness outbreaks in the United States. In South Dakota alone, kindergarten vaccination rates have gradually declined over the past decade. Such vaccine hesitancy and decreasing vaccination rates is a public health concern and must be addressed. Accessible patient education resources on the topic are necessary to increase vaccination rates.

Calcineurin-Mediated Immunosuppressants in Binge Ethanol Drinking and Stress Responsivity

Emily Kirschenmann MD | Patrick J. Ronan PhD

Introduction: Previous research has found that the calcineurin-mediated immunosuppressants cyclosporine A (CsA) and tacrolimus inhibit binge alcohol drinking in mice. Further research has shown that this effect is mediated directly in brain, as intracerebroventricular administration also significantly decreases drinking. As these immunosuppressants have severe systemic toxic effects along with dangerous inhibition of immune function, our goal is to determine proximal mechanisms by which these immunosuppressants are working in order to develop effective treatments for alcohol use disorder (AUD) with fewer side effects. One …
