In Vivo Evaluation Of Novel Nanoparticles And Repurposed Pharmaceuticals To Combat Antimicrobial Resistance, Sarah E. Evans

Theses, Dissertations and Capstones

In a 2019 report by the Centers for Disease Control and Prevention (CDC), infections resistant to antibiotic treatment amount to about three million infections and 48,000 deaths. Antimicrobial resistance is an escalating global threat as existing antibiotics lose efficacy over time. The project described is focused on partnering with pharmaceutical researchers and producers to test new nanoparticle-based or repurposed compounds. The central hypothesis of this thesis is that pharmaceutical formulations such as nanoparticles may provide a cost-effective means of combating the emerging antimicrobial resistance. The nanoparticle compounds allowed for a wide range of customization for the pharmaceutical design, since the …

Pgc-1Α Activation To Enhance Macrophage Immune Function In Mycobacterial Infections, Joel R. Frandsen, Zhihong Yuan, Brahmchetna Bedi, Zohra Prasla, Seoung-Ryoung Choi, Prabagaran Narayanasamy, Ruxana Sadikot

Journal Articles: Pathology and Microbiology

Nontuberculous Mycobacteria (NTM) are a heterogeneous group of environmental microorganisms with distinct human pathogenesis. Their incidence and prevalence are rising worldwide, due in part to elevated antimicrobial resistance which complicates treatment and potential successful outcomes. Although information exists on the clinical significance of NTMs, little is known about host immune response to infection. NTM infections alter macrophage mitochondrial capacity and decrease ATP production, efficient immune response, and bacterial clearance. Transcription factor peroxisome proliferator activated receptor (PPAR) γ coactivator-1α (PGC-1α) is a master regulator of mitochondrial biogenesis, influencing metabolism, mitochondrial pathways, and antioxidant response. Mitochondrial transcription factor A (TFAM) is a …

Evaluating The Effectiveness Of Teledermatology For Undeserved Populations During And Post-Covid-19, Jakob Gibbs, Sean Hanshaw

Theses, Dissertations and Capstones

Introduction: Teledermatology, a subset of telemedicine, has gained prominence as a means to increase access to dermatologic care while reducing costs and improving patient satisfaction. The swift expansion of teledermatology during the COVID-19 pandemic was driven by the necessity to limit physical contact and adapt to public health restrictions. This technological shift aimed to address longstanding disparities in dermatology access, especially in rural and underserved populations, and to respond to the rising demand for dermatologic services amid provider shortages.

Purpose of the Study: The purpose of this study was to analyze the effects that teledermatology following the COVID-19 pandemic had …

Case Report Of Neurosyphilis, Caroline Finnerty, Elizabeth Diaz, Teena Mathew

North Texas Research Forum 2025

This is the case of a 29 year old female who initially presented with generalized joint aches noted to have neurosyphilis. Because of her delayed treatment, this case presents interesting findings that we classically no longer see in syphilis cases due to early detection and treatment. The case looks at the early symptoms as well as late symptoms if syphilis is left untreated. The patient was ultimately treated with IV penicillin with improvement of her symptoms.

When Skin Necrosis Mimics: Diagnostic And Therapeutic Challenges Of Calciphylaxis In A Ckd Patient With A Mechanical Heart Valve, Sienna Luk, Harshil Parekh, Vaishnavi Singh, Darshan Bhatty, Sathish Karmegam

North Texas Research Forum 2025

Calciphylaxis is a rare but serious condition characterized by the calcification and thrombosis of small blood vessels, predominantly affecting patients with end-stage renal disease (ESRD). Diagnosis can be challenging due to overlapping features with other vascular conditions, such as warfarin-induced skin necrosis (WSN). We present a case of a patient with ESRD and typical risk factors—peritoneal dialysis, hyperparathyroidism, and warfarin use—who exhibited classic skin findings suggestive of calciphylaxis. However, two skin biopsies were inconclusive. Management involved addressing the patient's calciphylaxis risk factors, optimizing dialysis, and initiating sodium thiosulfate therapy. The case was further complicated by the need to replace warfarin, …

Challenges In Public Health: The Diagnosis And Treatment Of Crusted Scabies, Marshall Hall, Alyssa Forsyth, Wenquin Du, Michael Carletti, Stephen Weis

North Texas Research Forum 2025

Introduction: Common scabies is a parasitic dermatologic condition that often presents as an extremely pruritic rash. A rare and highly contagious variant of common scabies is crusted scabies, formerly known as Norwegian scabies. While infection with common scabies typically involves 10 to 20 mites, individuals with crusted scabies are burdened with thousands to millions of mites. Crusted scabies is characterized clinically by hyperkeratotic papules and plaques, most commonly on the palms and soles. Due to the variety of presentations seen in scabies, it can be difficult to diagnose. Case presentations: We present 4 cases of crusted scabies. An 89-year-old male …

Necrotizing Alternaria Pneumonia In An Immunocompetent Male, Joel Mathews, Jose Aguilar-Martinez, Sean Sojdie, Zain Tariq, Tamer Hudali

North Texas Research Forum 2025

Abstract: Alternaria species is a rare cause of invasive fungal pneumonia, typically described as an opportunistic pathogen, usually seen in immunocompromised patients producing virulent forms of sinus, cutaneous, and ocular infections. Alternaria species sparingly affect immunocompetent individuals and are often managed without any medical interventions. We present a case of invasive fungal necrotizing pneumonia caused by Alternaria alternata species in an immunocompetent 28-year-old male with only a past medical history of well-controlled asthma managed with an as-needed albuterol inhaler. His complaints included worsening foul-smelling productive cough with yellow-dark brown sputum along with subjective fevers, chills, chest pain, and dyspnea for …

Species-Specific Discrimination Of Bacterial Biofilms Using A Ratiometric Fluorescence Sensor Array And Machine Learning, Ritika Gupta, Aayushi Laliwala, Elena Muldiiarova, Kenneth W. Bayles, Denis Svechkarev, Marat Sadykov, Aaron M. Mohs

Journal Articles: Pathology and Microbiology

Biofilms are intricate bacterial communities encased in a self-produced extracellular matrix (ECM) of DNA, lipids, proteins, and polysaccharides. The diverse ECM composition across bacterial species significantly influences the progression of biofilm-associated infections, making precise identification crucial for effective treatment. Traditional methods such as biochemical assays, MALDI-TOF mass spectrometry, DNA sequencing and culturing provide valuable insights but have notable drawbacks, including time-consuming procedures, high costs, and the need for specialized equipment and trained personnel. These limitations hinder the rapid and widespread adoption of biofilm identification in clinical settings, underscoring the need for more streamlined, accurate, and accessible methods.

Hydralazine Induced Anca Vasculitis, Justin Huang, Yasasvi Sabbineni, Sumanth Reddy, Hani Khair

North Texas Research Forum 2025

Hydralazine is a vasodilator commonly used for hypertension. Hydrazine is commonly used in patients who can not tolerate ACEs and ARBs, resistant hypertension, and during pregnancy. Hydralazine has also been implicated in ANCA-associated vasculitis and drug-induced lupus erythematosus. Vasculitis is the presence of inflammatory leukocytes in vessel walls, inflammation can cause loss of vessel integrity which can lead to bleeding and downstream tissue ischemia and necrosis. Antineutrophil cytoplasmic antibody (AΝCΑ)-associated vаsсulitiѕ (ΑΑV) is a necrotizing vаsсսlitis that does not substantially involve the deposition of immune complexes. AΑV predominantly affects small vessels and is associated with ANСΑ specific for myeloperoxidase (MPO-ΑNCΑ) …

Challenges Faced In Managing The Hemodynamic Status Due To Recurrent Gastrointestinal Bleeding In Typhoid Fever With Uncorrected Double Outlet Right Ventricle Patient: A Case Report, Kellyn Trycia Zenjaya, Lindawati Wijoyo, Jovan Amadeo Muliyanto, Rizqi Rokhmadhoni Pikir, Dwi Putri Lestari, Esthy Poespitaningtyas

Journal of the Hong Kong College of Cardiology

Double Outlet Right Ventricle (DORV) is a rare cyanotic congenital heart defect often associated with polycythemia and bleeding risk. A 7-year-old boy with uncorrected DORV presented with fever, melena, and shock. He was cyanotic, tachypneic, and tachycardic, with SpO₂ of 68% and a harsh ejection systolic murmur. Labs showed anemia, thrombocytopenia, leukocytosis, and prolonged APTT. Tubex TF IgM was strongly positive. A diagnosis of typhoid fever with gastrointestinal bleeding and uncorrected DORV was made. Management included oxygen, inotropes, and fluid resuscitation. Propranolol was withheld. Severe infection with underlying cyanotic heart disease and coagulopathy presents a critical management dilemma.

Investigating Mono-Driver Versus Multi-Driver Oncogenesis Via Alterations To Cell Signaling Pathways, Abygail Chapdelaine

Open Access Dissertations

The latest edition of Global Cancer Statistics released by the American Cancer Society reported approximately 20 million newly diagnosed cancer cases worldwide in 2022 with 9.7 million deaths. This ranks cancer as the second leading cause of death worldwide. For the majority of cancer patients, the standard treatment approach is chemotherapy and/or radiation therapy, and while this has been successful in some patients, a lack of specificity to cancer cells causes severe side-effects when these agents damage healthy cells. Despite extensive efforts that have gone into developing targeted cancer therapeutics that block functions specific to cancer, they have not been …

Acute Hepatitis B Infection In A Patient With Confirmed Immunity On Long-Acting Cabotegravir/Rilpivirine, William K B Boateng, Neil Carlin, Etan Spira, Maria E Szabela, Kosisochukwu J Ezeh

Faculty and Staff Publications

Long-acting injectable formulation of cabotegravir/rilpivirine (CAB/RPV) is a promising novel maintenance therapy for HIV infection. However, coinfection with active hepatitis B virus (HBV) infection is a contraindication to initiating this therapy. Despite guidelines, patients with HBV immunity can still contract acute HBV infection. We report a case of a 30-year-old man with HIV who transitioned from antiretroviral therapy to CAB/RPV and had confirmed HBV immunity. The patient, though asymptomatic, showed significantly elevated liver function tests (LFTs) before his monthly CAB/RPV injection. He was hospitalized and diagnosed with acute HBV infection. His LFTs improved, and he was taken off CAB/RPV and …

Cryptococcal Meningitis In A Patient With Multiple Sclerosis On Fingolimod, Syed Hassan Amir, Teena Mathew

North Texas Research Forum 2025

Background: There are a host of pathogens that thrive only when the host is weakened enough to be susceptible – Cryptococcus is one such organism that causes fatal meningitis, primarily in HIV patients. Those immunocompromised by other means are also susceptible. Among them, patients with multiple sclerosis (MS) pose a significant challenge as what may initially be considered an MS flare could mask a serious underlying infection. Objective: This case study discusses an MS patient on Fingolimod, an immunosuppressant, that likely made them vulnerable to cryptococcal meningitis. Pathogenesis: Cryptococci are encapsulated yeast that enter the body via inhalation of spores …
