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 …

A Painful Diffuse Rash, Bruce M. Lo, Melanie Shoemaker, Kiersten Potter, Katherine Schaffer

Department of Emergency Medicine Faculty Publications

[Patient presentation]

A 41-year-old male with no past medical history presented with 1 week of ulcers to the left side of his face, followed by several days of a painful rash to the trunk and back after a sexual encounter. The patient denies any fever or previous rash and any illicit drug use. Initial vital signs included a temperature of 97 °F, a heart rate of 89 beats per minute, and blood pressure of 135/79 mm Hg. Physical examination revealed a macular papular rash across his trunk and back (Fig 1) and facial ulcerations with eschar (Fig 2) at the …

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 …

Reducing Respiratory Viral Testing In A Pediatric Emergency Department: A Quality Improvement Initiative, Anna Suessman

North Texas GME Research Forum 2026

Background: Respiratory viral testing in pediatric emergency departments (EDs) is frequently performed despite limited impact on clinical management for many low-risk presentations. Unnecessary testing increases cost and operational burden may delay patient throughput and can provide false reassurance to caregivers. Additionally, pediatric emergency department nurses agreed with overburden and impact to throughput based on overuse of viral testing (qualitative nursing survey conducted on September 4, 2024 showed >98% felt testing was unnecessary). We hypothesized that reducing testing through standardized team education and discharge processes would not negatively affect patient experience. This initiative aimed to decrease unnecessary respiratory viral testing during …

An Unusual Case Of Genetic Dilated Cardiomyopathy Unmasked By Covid-19 Infection, Greeshma Molugu, Daniel Mcmahan, Seline Haci, Giridhar Mundluru, Machaiah Madhrira

North Texas GME Research Forum 2026

Introduction: Titin (TTN) mutations are a well-known cause of dilated cardiomyopathy (DCM), occurring in approximately 25% of familial cases of idiopathic DCM and 18% of sporadic cases. Recognition and referral for genetic testing remains underutilized but has important prognostication and helps the patient better understand the disease transmission. This case report stresses the importance of a complete evaluation for genetic causes of DCM.

Case Presentation: A 21-year-old male who was adopted as an infant was hospitalized with COVID-19 infection and diagnosed with non-ischemic cardiomyopathy with an initial left ventricular ejection fraction (EF) of 10%. He was assumed to have DCM …

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 …

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 …

Establishment Of A Conditionally Replicating Guinea Pig Cytomegalovirus Model For Molecular Characterization Of Latency, Akshay R. Molakalapalli, Saketh Majeti, Michael A. Mcvoy, Jian Ben Wang

UROP Posters

Human cytomegalovirus (HCMV) is a member of the Herpesviridae that establishes life-long latent infections that pose risks of life-threatening disease upon reactivation in immunocompromised individuals. Understanding the molecular mechanisms that govern the latent state is critical for developing effective treatments. However, molecular characterization has been impeded by the scarcity of latently infected cells in vivo and the inability of current in vitro models to support the expansion of clonal latent cell lines. To address these limitations, we developed a novel cell culture model utilizing a conditionally replicating guinea pig cytomegalovirus, a relative of HCMV that mimics HCMV pathology and provides …

Variability In Parainfluenza Virus Derived From Persistently Infected Lung Epithelial Cells, Cassidy R. Conte

Honors Undergraduate Theses

An acute infection (AI) with RNA virus can progress to a persistent infection (PI) where infected cells continue to grow and replicate while producing progeny virions. PIs with respiratory viruses are clinically important, as they can lead to prolonged shedding of viruses and generation of mutant viruses that are altered in pathogenesis and/or immune responses. Parainfluenza type 5 (PIV5) is a prototypic RNA virus shown to cause PIs in cell culture. Plaques in tissue culture from an acute infection with parental PIV5 were homogeneous in size and shape. By contrast, plaques from PIV5 persistently infected cells were heterogeneous, having a …

When Unilateral Leg Swelling Is Not Deep Vein Thrombosis: A Case Of Disseminated Kaposi Sarcoma Revealing Advanced Human Immunodeficiency Virus, Ahmed Ismail, Zachary Wilson, Thomas Currow, Michael Dileonardo, Carsten Kirby

Department of Medicine Faculty Publications

Kaposi sarcoma (KS) is an acquired immunodeficiency syndrome (AIDS)-defining malignancy that can involve the skin, lymph nodes, and visceral organs in patients with advanced human immunodeficiency virus (HIV). We report the case of a 35-year-old man with no known prior medical history who presented to the charity care clinic complaining of recurrent thrush and two weeks of progressive right lower extremity swelling. His physical examination revealed painful, pruritic violaceous papules and plaques over the proximal right thigh that had been present for one week. He was referred to the emergency department (ED) for further workup. Venous duplex ultrasonography was negative …
