The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-induced coronavirus disease 2019 (COVID-19) pandemic has challenged the current understanding of the complement cascade mechanisms of host immune responses during infection-induced nonresolvable lung disease. While the complement system is involved in opsonization and phagocytosis of the invading pathogens, uncontrolled complement activation also leads to aberrant autophagic response and tissue damage. Our recent study revealed unique pathologic and fibrotic signature genes associated with epithelial bronchiolization in the lung tissues of patients with nonresolvable COVID-19 (NR-COVID-19) requiring lung transplantation. However, there is a knowledge gap if complement components are modulated to contribute to tissue …

North Texas Research Forum 2025

Background Patients with massive/sub-massive pulmonary embolism (PE) and right ventricular strain have a significant risk of hemodynamic collapse. VA ECMO support provides an excellent salvage option for patients with acute/unstable pulmonary embolism with obstructive cardiogenic shock undergoing mechanical thrombectomy. Using VA-ECMO for a “protective PE” procedure allows control of hemodynamics and enables interventionalists to perform the thrombectomy in a more controlled environment. Here, we present our experience. Methods A retrospective data analysis on consecutive VA ECMO patients with cardiogenic shock secondary to pulmonary embolism was abstracted from August 2022 to June 2024. Results Patient characteristics and outcomes are described in …

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 …

Zinc Promotes Mitochondrial Health Through Pgc-1alpha Enhancing Bacterial Clearance In Macrophages Infected With Mycobacterium Avium Complex, Ruxana Sadikot, Prabagaran Narayanasamy, Zhihong Yuan, Deandra R. Smith, Daren L. Knoell

Journal Articles: Pulmonary & Critical Care Med

Mitochondria are increasingly recognized as important contributors to immune function, in addition to energy production. They exert this influence through modulation of various signaling pathways that regulate cellular metabolism and immune function in response to pathogens. Peroxisome proliferator-activated receptor (PPAR) coactivator 1 alpha (PGC-1α) is the primary transcription factor and regulator involved in mitochondrial biogenesis. Long known to be involved in immune function, zinc (Zn) is also required for proper mitochondrial function. It is increasingly recognized that many cellular immunometabolic activities are also Zn-dependent. Taken together, we investigated the role of Zn deficiency, both dietary and genetically induced, and Zn …

Gallium Β-Cyclodextrin Nanoparticles Containing Both Gallium Protoporphyrin And Gallium Nitrate Exhibit Antimicrobial Activity Against Nontuberculous Mycobacteria In Vitro And In Vivo, Seoung-Ryoung Choi, Bradley E. Britigan, Prabagaran Narayanasamy

Journal Articles: Pulmonary & Critical Care Med

Effective and safe antibiotics active against pathogenic mycobacterial species are needed. Iron is an essential element for bacterial survival. Ga(NO₃)₃ (GN) and Ga protoporphyrin (GP) as iron mimetics have each been shown to inhibit the iron metabolism and growth of various mycobacterial species. In this study, the dual cyclodextrin nanoparticle (CDGPGN) is prepared that carries GP and GN using a sonication homogenization technique to increase the efficacy of the combination therapy. CDGPGN shows a long-acting antimicrobial activity against Mycobacteroides abscessus residing in monocyte-derived macrophages (MDM). A murine pulmonary study showed that the CDGPGN also inhibited the growth …

Navigating The Complexity Of Ards And Cardiogenic Shock With Veno-Arterial Ecmo: A Case Report, Sanjana Kesireddy, Mohan Sengodan

North Texas Research Forum 2025

INTRODUCTION: When deciding between VA ECMO (veno-arterial ECMO) and VV ECMO (veno-venous ECMO), the primary consideration is the underlying pathology affecting the patient’s heart and lungs. VA ECMO provides support for both the cardiovascular and respiratory systems, making it suitable for patients experiencing cardiogenic shock or combined cardiac and respiratory failure. In contrast, VV ECMO is used exclusively for respiratory failure, offering support to patients with severe lung dysfunction but intact cardiac function. CASE PRESENTATION: 41 year old male with no known past medical history presented s/p cardiac arrest secondary to aspiration pneumonia due to alcohol and opioid intoxication. Chest …

Doctor of Nursing Practice (DNP) Scholarly Projects - Archive

The implementation of the asthma follow-up visits bundle in the pediatric primary care setting is an evidence-based practice project aimed at improving pediatric asthma management. This manuscript discusses the deployment of the bundle, which includes pre- and post- knowledge assessment for parents/caregivers, asthma education through a short video and handout, administration of the asthma control test (ACT), completion of a written asthma action plan (WAAP), and education about the patient portal and telehealth. The goal is to improve parent/caregiver knowledge, treatment adherence, follow-up visit compliance (in-person or virtual) and reduce emergency department (ED) utilization. Parent/caregiver knowledge increased by 23%, ACT …

Effects Of Educational Intervention On Asthmatic Children, Zoe Coggins

Nursing | Senior Theses

Abstract

Children are more vulnerable to asthmatic symptoms due to the physiological immaturity of their respiratory systems. Therefore, irritants are deemed more hazardous for the pediatric population. Pollution is a growing health concern, and within the literature review, several approaches to the measurement of the impact of low air quality and educational interventions are discussed. The themes identified in the literature review are increased risk of pollution-induced exacerbation due to age, behavior, and residential proximity to emission-producing facilities. The review of the literature demonstrated how pollution is a growing public health concern, especially among the pediatric population. Interventions, reviewed in …

Platypnea-Orthodeoxia Syndrome In A Case Of Septal Occlusion Device Migration, Bike Ozkan, Richard Shalmiyev, Adam Devine, Michael Pelekhach, Siddarth Kathuria, Daniel Heller, Mauricio Danckers

East Florida Division GME Research Day 2025

Introduction

Platypnea-orthodeoxia syndrome (POS) is defined by dyspnea and hypoxemia in the upright position, which improves upon recumbency. While often linked with hepatopulmonary syndrome, intracardiac etiologies, particularly a patent foramen ovale (PFO), may also be responsible. PFOs are typically managed with device closure, and while rare, device migration can occur unbeknownst to the patient with resultant critical sequelae.

Methods

Here, we present the case of an 89-year-old female with a medical history of hypertension, diabetes, and coronary artery disease status post PCI, who arrived with severe dyspnea and was subsequently intubated for profound hypoxia. A chest CT angiogram ruled out …

Oil And Air Don’T Mix: Vitamin E Acetate In Evali, Angelo Lopez-Lacayo, Jordan Taylor-Bentley, Josef Masseli, Michelle Silva, Christy Diaz, Daniel Zapata

East Florida Division GME Research Day 2025

Introduction: Electronic cigarette or vaping-associated lung injury (EVALI) is an acute or subacute condition characterized by acute respiratory symptoms and bilateral pulmonary infiltrates seen in patients who are exposed to electronic cigarettes or vapes. The condition has been strongly linked to inhalation of aerosolized vitamin E acetate, particularly in THC-containing e-cigarette products. Despite regulation of vitamin E acetate in the production of electronic vapes, it continues to be a byproduct of EVALI due to counterfeit electronic vapes. Clinically, patients with EVALI present in various ways but are not limited to fever, shortness of breath, cough, chills, body aches, pleuritic chest …

Introduction: Thoracic endometriosis syndrome (TES) is a rare condition in which functional endometrial tissue spreads to the thoracic cavity. Manifestations of TES include catamenial hemoptysis, pneumothorax, and pleural effusions along with symptoms of dyspnea, cough, and pleuritic chest pain.1 Approximately 6 to 10% of women of reproductive-age women develop TES with concurrent pelvic endometriosis in 80% of patients.2 Treatment of TES includes medical management with progesterone-based oral contraceptive pills (OCPs) and surgical management involving cardiothoracic surgery. We present a case of recurrent pleural effusions in a patient who was non-compliant with medical management of TES. Methods: Data was collected during …

Combination Of Hsp90 Inhibitors And Hsp70 Inducers Prevent Hydrochloric Acid-Induced Pulmonary Fibrosis In Rabbits, Ruben M. L. Colunga Biancatelli, Pavel A. Solopov, Tierney Day, Dan E. Austin Jr., Len E. Murray, John D. Catravas

Bioelectrics Publications

Combined therapies with Heat Shock Protein 90 (HSP90) inhibitors and Heat Shock Protein 70 (HSP70) inducers are gaining significant interest in cancer and cardiovascular research. Here, we tested the hypothesis that HSP90 inhibitors and HSP70 inducers, together, can block the development of pulmonary fibrosis. We exposed New Zealand White Rabbits to hydrochloric acid (HCl, 0.1 N, 1.5 mL/kg), one of the top five chemicals most commonly involved in accidental exposures and inhalation injuries worldwide, and treated animals with either the orally available HSP90 inhibitor TAS-116 (1.7 mg/kg 5x/week) or TAS-116 combined with the HSP70 inducer, geranylgeranyl acetone (GGA, 50 mg/kg, …

Editing Approaches To Treat Alpha-1 Antitrypsin Deficiency, Derek M. Erion, Leah Y. Liu, Christopher R. Brown, Stephen I. Rennard, Humam Farah

Journal Articles: Pulmonary & Critical Care Med

TOPIC IMPORTANCE: Alpha-1 antitrypsin (AAT) deficiency is a genetic disorder most commonly due to a single G to A point mutation (E342K), leading to debilitating lung and/or liver disorders and is associated with increased mortality. The E342K point mutation causes a conformational change of the AAT protein resulting in its retention in liver hepatocytes. This reduces AAT secretion into the serum resulting in higher protease activities due to the lack of inhibition from AAT, causing damage to healthy lung tissue. The current standard of care for lung manifestations involves weekly IV augmentation therapy and is considered suboptimal for these patients. …

Exploring Psychological Implications Of The Contemporary Lung Transplant, Isaac C. Machar

Williams Honors College, Honors Research Projects

Since its inception in 1963 at the University of Mississippi Medical Center, more than 50,000 lung transplant procedures have been performed. During its 50-year anniversary, 2023 saw just over 3,000 lung transplants performed in the United Sates. However, as this procedure continues to increase in execution each year, it is critical that the psychological implications of this procedure are explored. In this paper, I hope to develop an understanding of the psychological background of contemporary lung transplantation. Reviewing the lung and double lung transplant, the goal is to apply biopsychology principles to the field. Background information about transplant science is …
