North Texas GME Research Forum 2026

Peri-partum infective endocarditis (IE) is a rare but serious condition with high maternal and fetal morbidity and mortality. IE is exceedingly uncommon in young healthy patients, especially without any known risk factors such as intravenous (IV) drug use, congenital heart disease, or rheumatic heart disease. IE is estimated to complicate 0.00002% of in-hospital deliveries. Similar to the general population, staphylococcal and streptococcal species remain the most common pathogens in obstetric patients. Enterococcal species make up less than 10% of IE cases in pregnant women. Very few cases of enterococcal IE in the post-partum period are reported in the literature. We …

The Rapid Case Of Anoxic Brain Injury Secondary To Hyperammonemia, Jacqueline Bekhit, Ngoc Vu, Jiaming Xue, Gabriella David, Qasim Sajawal

North Texas GME Research Forum 2026

Background: Acute hyperammonemia presents as a toxic state with the clinical presentation as altered consciousness, seizures, and coma. Hyperammonemia disrupts astrocytes osmotic balance via glutamine accumulation, triggering brain edema, inflammation, and apoptosis whom mechanism is closely parallel to hypoxic ischemic injury. This overlap necessitates differentiating metabolic causes from hypoxic etiologies, as timely ammonia clearance therapies can prevent catastrophic outcomes. This case underscores the need for close clinical vigilance and early recognition of severe hyperammonemia

Case Presentation: A 65-year-old woman with metabolic dysfunction-associated steatotic liver disease related cirrhosis complicated by recurrent ascites requiring bimonthly paracentesis presented with abdominal distension and pain. …

A Rare Case Of Disseminated Strongyloidiasis Causing Polymicrobial Sepsis In A Patient With Lupus: A Diagnostic Conundrum, Greeshma Molugu, Anupama Chennupati, Ayo Dereje, Machaiah Madhrira

North Texas GME Research Forum 2026

Introduction: Disseminated strongyloidiasis is a very rare condition with case-fatality rates approaching 90%. However, the diagnosis is often delayed because of nonspecific presenting symptoms. Early diagnosis relies on a high index of clinical suspicion, especially in immunocompromised hosts. Long-term corticosteroid therapy, leading to some suppression of inflammatory and immunologic responses, is a well-known risk factor for severe strongyloidiasis.

Case presentation: A 52-year-old male with a past medical history of lupus on chronic corticosteroid therapy presented with chief complaints of dyspnea and diarrhea. He has a recent history of travel to Mexico. Hemoglobin was 5.3. CTAP with contrast showed diffuse colitis …

Surveillance Of A Novel Vesivirus Discovered In An Urban Mephitis Mephitis Population, Amanda E. Diggins

Honors Theses and Capstones

Caliciviridae is a family of non-enveloped, positive-sense, single stranded RNA viruses, including eleven defined genera that contain important pathogens of humans and animals. Within the Caliciviridae family, the genus Vesiviridae includes feline calicivirus, a leading cause of upper respiratory disease in cats, and vesicular exanthema of swine virus, a historical disease of domestic swine that has now been implicated in several marine mammal vesicular diseases, one of which has been confirmed zoonotic. Urban landscapes create a unique environment for rapid intra- and interspecies transmission of viruses. Clustered resources attract high-density populations of synanthropic wildlife species, increasing spatial overlap and heightening …

Environmental Predictors Of Human Lyme Disease Incidence Across Appalachian Counties In Kentucky, Virginia, And West Virginia, 2000-2019, Karlie D. Rennison

Theses and Dissertations--Epidemiology and Biostatistics

This ecological study examined county-level environmental, landscape, and host-related predictors of Lyme disease incidence across Kentucky, Virginia, and West Virginia from 2000-2019. Lyme disease is an emerging public health concern in the Appalachian region, where geographic expansion and shifting ecological conditions may influence disease risk.

Lyme disease case rates (per 10,000 population) were analyzed in relation to climate variables, land cover metrics, host density measures, and rurality using publicly available data sources. Descriptive and regression analyses were conducted to evaluate associations between candidate predictors and disease incidence.

Substantial geographic variation in Lyme disease incidence was observed, with higher case rates …

Politics Of A Silent Pandemic: Antimicrobial Resistance And State Capacity In India And Nigeria, Mia Kelly

CMC Senior Theses

Antimicrobial Resistance (AMR) has emerged as one of the most pressing yet widely underestimated health threats of the 21st century; this thesis explores the potentially devastating global impact of this “silent pandemic”, exposing how deeply health outcomes depend on political choices, regulatory capacity, and economic constraints. Although the danger of spreading drug-resistant pathogens is now widely acknowledged in both the scientific and political communities, states differ in their abilities to contain the issue, with low- and middle-income countries facing the greatest obstacles to national action plan implementation. This thesis investigates these disparities through a comparison of India and Nigeria, two …

Roles Of Cytokines In Modulating Trypanosoma Brucei Rhodesiense Infection Outcomes In Vervet Monkeys, Clarah Jebet, John Kibuthu Thuita, Daniel Masiga, Benedict Owino Orindi, John Oidho, Mark C. Field, Enock Matovu, Vincent Owino Adung’A

All Peer-Reviewed Publications

Introduction:

Human African trypanosomiasis (HAT), caused by Trypanosoma brucei rhodesiense, is categorized as acute due to rapid disease progression but presents varying clinical outcomes. Although the mechanisms underpinning differential clinical progression are poorly understood, both host and parasite factors are implicated. Therefore, we sought to elucidate roles of primate host factors in mediating varying T. b. rhodesiense infection outcomes.

Methods:

Here, we assessed the roles of selected host cytokines in disease progression using a tsetse-mediated infection in a non-human primate (NHP) vervet monkey model that closely mimics HAT and natural infection. We quantified eight cytokines, including TNF-α, IFN-γ, IL-10, IL-6, …

North Texas GME Research Forum 2026

BACKGROUND/ INTRODUCTION: Calcinosis cutis is a rare but serious complication of end-stage renal disease (ESRD), often related to disordered calcium–phosphate metabolism. It can lead to significant morbidity, recurrent infections, and challenging management decisions.

CASE PRESENTATION: We present a 23-year-old male with ESRD on hemodialysis, hypertension, anemia of chronic disease, and a left upper extremity arteriovenous fistula who developed progressive pain, swelling, and purulent drainage involving the left third and fourth digits. Imaging revealed extensive soft tissue calcifications consistent with calcinosis cutis. His hospital course was complicated by recurrent infections, osteomyelitis, and gangrene despite antibiotic therapy and wound care, ultimately requiring …

Septic Arthritis Suspected But Pseudogout Confirmed: The Importance Of Early Joint Aspiration And Crystal Analysis, Munazzah Kaleem, Jose Lozano

North Texas GME Research Forum 2026

BACKGROUND/ INTRODUCTION: Septic arthritis present as an acute monoarticular arthritis and is highly suspected in patients with risk factors including DM, ESRD, and bacteremia. As a result, empiric antibiotics are usually started prior to definitive diagnosis. But crystal induced arthropathies closely mimic septic arthritis in their presentation. This case highlights the importance of early arthrocentesis to avoid unnecessary antibiotic treatment.

CASE PRESENTATION: 50-year-old female on antibiotics for MSSA bacteremia presented due to acute onset left hip pain, swelling and decreased range of motion. No trigger was present. PMH included HTN, T2DM and ESRD on HD. She denied fever, chills or …

Invasive Pulmonary Aspergillosis: A Two-Year Journey, Jason Woods, Padmaditya Sureddi, Nga Van, Danielle Ford

North Texas GME Research Forum 2026

BACKGROUND: Highly active anti-retroviral therapy (HAART) has decreased the incidence of opportunistic infections among persons with HIV. Invasive aspergillosis specifically is uncommon among individuals with clusters of differentiation 4 (CD4) count >100 cells/mm3. Furthermore, treatment of aspergillosis in the HIV-infected population has not been examined systematically. We report a patient with CD4 count >200 cells/mm3, compliant with HAART therapy who developed invasive pulmonary aspergillosis (IPA) over the course of two years that was successfully treated through a combination of bronchial artery embolization and liposomal amphotericin.

CASE PRESENTATION: A 56-year-old man from southern Africa with four-year history of HIV-1 on HAART …

Impact Of Mips Measure 66 On The Incidence Of Pta's, Sydney Finch, Christopher Houston

North Texas GME Research Forum 2026

INTRO

A number of randomized controlled trials indicate that using point-of-care group A strep (POC GAS) testing decreases antibiotic utilization without compromising health outcomes. In 2018, the Merit-based Incentive Payment System (MIPS) measure 66 went into effect requiring the testing for GAS when treating pharyngitis. The intent was to decrease the unnecessary use of antibiotics in the treatment of pharyngitis, given that most cases are viral. Anecdotally, some physicians have noticed the increased incidence of peritonsillar abscesses (PTA). Our research group aims to investigate if there has been a significant increase in incidence of PTAs after the implementation of MIPS …

Bariatric Surgery Impacts Immune Cell Metabolism And Function Dependent On Metabolic Status, Samantha N. Hart

University of Kentucky Doctoral Dissertations

Type 2 Diabetes (T2D), one of the top ten causes of death worldwide, is fueled by chronic inflammation. T2D is considered a metabolic disease, and there is a great push to target metabolic and associated inflammatory pathways to ameliorate the disease & its comorbidities i.e., obesity and cardiovascular disease. Thus far, clinical trials of anti-inflammatory drugs have had modest impacts on T2D and have not led to changes in clinical practice. This may in part be due to a gap in knowledge in the mechanism(s) driving obesity-associated chronic inflammation. I posit that metabolic abnormalities in immune cells in those with …

Repurposing Cyclin-Dependent Kinase Inhibitors For The Discovery Of Novel Antiplasmodial Compounds, Ritam Bhowmik

Honors Undergraduate Theses

Malaria remains a major global health burden with over 282 million cases annually and rising resistance to artemisinin-based combination therapies. Plasmodium falciparum, the most lethal malaria parasite species in humans, relies on tightly regulated cell cycle progression during replication within red blood cells. Cyclin-dependent kinases (CDKs) are central regulators of eukaryotic cell division and transcription, and several CDK-like enzymes in P. falciparum, including Pfmrk and PfPK6, are essential for parasite growth and structurally distinct from human kinases. This study evaluated whether commercially available human CDK inhibitors (CDKIs) targeting cancer pathways could be repurposed as novel antimalarial compounds. A library of …

Chronic psychosocial stressors contribute to cardiovascular disease (CVD) and related risk factors, particularly in under-resourced communities. Psychosocial stressors activate the hypothalamic-pituitary-adrenal (HPA) axis, leading to sustained cortisol action on immune cells. Natural killer (NK) cells are altered in distribution and function in cardio-metabolic diseases; however, pathways linking cortisol as a marker of chronic stress to NK cell dysfunction remain understudied. We recruited 186 African American women from the Step It Up Community-Engaged, Digital Health Physical Activity Intervention study and collected cortisol, NK cell measures, and psychosocial stress measures using validated questionnaires, including chronic stress and loneliness. Plasma cortisol levels were …

Mortality From Or With Covid-19 Infection, Dagan Coppock, Joseph Glowacki, Constantine Daskalakis, John Zurlo, Nikita Jaggernauth, Daniel Taupin

Division of Infectious Diseases and Environmental Medicine Faculty Papers

In this retrospective study, we compared the cause of death among hospitalized patients who died with a diagnosis of COVID-19 across two periods of the pandemic two years apart: an early period (admissions June to October 2020), when the population was immunologically naïve, and a later period (admissions April to October 2022), when an estimated 96% of the population had immunity from prior infection, vaccination, or both. Two investigators independently reviewed the medical records of 100 in-hospital deaths (50 per period) and classified each death as COVID-19 related, uncertain, or not COVID-19 related, using logistic regression to compare the two …

Oropharyngeal Syphilis Presenting As Tongue Based Ulcer With Lymphadenopathy, Serena F. Pu, Kevin J. Carlson, Jonathan R. Mark, Benjamin J. Rubinstein

Department of Otolaryngology (ENT) Faculty Publications

Within the aerodigestive tract, syphilis presents with varied signs and symptoms, some of which may mimic malignancy or other disease processes. We present the case of a 29-year-old man with otalgia and odynophagia who was found on physical examination and office laryngoscopy to have a 4-cm ulcerative mass of the tongue base and cervical lymphadenopathy. While planning for tissue diagnosis, the patient’s serologies revealed positive treponemal antibody testing and elevated rapid plasma reagin (RPR) titers, confirming syphilitic infection, likely representing secondary syphilis. While awaiting operative biopsy, the patient received intramuscular penicillin with complete resolution of the mass and symptoms, and …

Comparative Spatial Biology: A Cross-Species Analysis Of Canine Oral Cancers As Models For Human Disease, Ram Pradhyumnan

Honors Undergraduate Theses

Oral squamous cell carcinoma (OSCC), one of the most common malignancies of the oral cavity, remains a clinically challenging disease due to its aggressive behavior, late-stage diagnosis, and limited improvements in therapeutic outcomes over recent decades. A significant barrier to progress in OSCC research and treatment is the lack of suitable preclinical models that recapitulate the complexity and natural progression of the disease. Most current models—including cell lines, xenografts, and genetically engineered mice—fail to capture key features such as the spatial organization of tumor epithelium, interactions with an intact immune system, and the stepwise evolution from normal mucosa to invasive …

Analysis Of Alternative Gene Splicing Of Natural Killer Cell Exhaustion Markers During Siv Infection, Soledad B. Zayas

Honors Undergraduate Theses

Natural killer cells play a critical role in the innate immune response against Human Immunodeficiency Virus and Simian Immunodeficiency Virus infections. During HIV/SIV infection, NK cells undergo functional impairment characterized by an imbalance between activating and inhibitory surface receptors. The upregulation of inhibitory receptors, TIGIT and TIM-3, has proven to contribute to NK cell exhaustion during different retroviral infections. Although alternative splicing regulates immunity related genes, its role in TIGIT and TIM-3 expression during SIV infection remains poorly understood. This study aimed to characterize alternative splicing patterns of TIGIT and TIM-3 and evaluate transcript variant expression during SIV infection in …

Nanoparticle Carriers Enhance The Prophylactic Antiviral Effects Of Dsrna In Vitro And Ex Vivo, Shayne Oberhoffner, Stephanie Dewitte-Orr, Starla Richardson, Leah Haile, Dominique Daniels, Erin Cooper, Aizah Ijaz, Janet Velasquez Perez, Mathilde Peruzzi, Bertrand Collet, Paul Craig, Kristof Jenik

Theses and Dissertations (Comprehensive)

Aquaculture now outpaces traditional capture fisheries as the world population and demand for sustainable protein sources increases. Wild and farmed species are increasingly susceptible to pathogen spread as global temperatures rise and stocking densities increase. Despite the devastating losses experienced by aquaculture due to viral infections, there remain few effective prophylactic antiviral therapeutics. Long double-stranded (ds)RNA is a uniquely viral molecule produced by nearly all viruses during their replication cycle, and its detection by salmonids like rainbow trout (Oncorhynchus mykiss) and chinook salmon (Oncorhynchus tshawytsha) leads to the establishment of a defensive antiviral state. Previous in vitro studies demonstrated a …

When Fever And Thrombocytopenia Are Not Infectious: A Case Of Vitamin B12 Deficiency Mimicking Tropical Fever, Ram Arvind Viswanathan Dr

Digital Journal of Clinical Medicine

Vitamin B12 deficiency is classically associated with megaloblastic anaemia and neurological manifestations; however, atypical presentations continue to pose diagnostic challenges. Fever in association with thrombocytopenia often prompts evaluation for infectious aetiologies such as dengue, malaria, or sepsis, particularly in tropical settings. We report a case of vitamin B12 deficiency presenting with pyrexia and isolated thrombocytopenia, initially suspected to be an infectious illness. Extensive evaluation failed to reveal an infective cause, and subsequent haematological workup demonstrated megaloblastic changes with low serum vitamin B12 levels. Remarkably, the patient showed rapid defervescence and normalisation of platelet counts following parenteral vitamin B12 therapy. This …
