The ability of immune cells to expand numerically after infusion distinguishes adoptive immunotherapies from traditional drugs, providing unique therapeutic advantages as well as the potential for unmanageable toxicities. Here, we describe a case of lethal hyperleukocytosis in a patient with neuroblastoma treated on phase 1 clinical trial (NCT03294954) with autologous natural killer T cells (NKTs) expressing a GD2-specific chimeric antigen receptor and cytokine interleukin 15 (GD2-CAR.15). This patient was the first to be treated on dose level (DL) 5 and the first patient whose product was restimulated with K562-derived artificial antigen-presenting cells (aAPCs) instead of autologous peripheral blood mononuclear cells …

Background/Objectives: Lung cancer is the primary cause of cancer-related deaths. Most patients are typically diagnosed at advanced stages. Low-dose computed tomography (LDCT) has been proven to reduce lung cancer mortality, but screening programs using LDCT are associated with a high number of false positives and unnecessary thoracotomies. It is therefore imperative that a certain diagnosis is refined, especially in cases of solitary pulmonary nodules that are difficult to technically access for an accurate preoperative diagnosis. Extracellular vesicles (EVs) involved in intercellular communication may be an innovative biomarker for diagnosis and therapeutic strategies in lung cancer, regarding their ability to carry …

Journal Articles: Pulmonary & Critical Care Med

BACKGROUND: Cigarette smoking is an important etiology for cardiac diseases and electronic cigarettes are increasing in popularity. In the current study, we assessed physiological and transcriptional changes in human induced pluripotent stem cell derived cardiomyocytes (iPS-CMs) after exposure to electronic cigarette extract (ECE) and conventional cigarette extract (CSE).

METHODS: iPS-CMS were plated on multi-electrode array plates (MEA), electrical and contractile properties were determined by Maestro Edge and computer assisted video analysis (MuscleMotion). Transcriptional profiles were accessed by direct digital mRNA detection of heart failure targeted genes.

RESULTS: Both ECE and CSE extracts significantly prolong beat period from baseline compared to …

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 …

Resilience And Reality: Exploring The Lived Experiences Of People Living With Hiv In Texas During The Covid-19 Pandemic – A Qualitative Study., Ahmed F. Alanazi

Social Work Dissertations - Archive

This study investigated the lived experiences of individuals living with HIV (PLWH) in the Dallas-Fort Worth (DFW) area of Texas during the COVID-19 pandemic, using an Interpretative Phenomenological Analysis (IPA) framework. The research examined the intersection of health, social dynamics, and psychological resilience among PLWH, who faced compounded vulnerabilities due to systemic inequities and the dual public health crises of HIV and COVID-19. Through semi-structured interviews with ten participants from diverse backgrounds, the study captured the profound impacts of disrupted healthcare systems, heightened stigma, and social isolation on this marginalized population. The findings reveal that the pandemic exacerbated existing inequities …

Prepared To Protect: Improving Cardiac Emergency Response Through Education And Action Planning In Youth Club Sports, Melissa Garcia

Nursing | Senior Theses

Sudden cardiac arrest (SCA) is the leading cause of death in youth sports, illuminating the essential demand for adequate emergency response, including cardiopulmonary resuscitation (CPR), automated external defibrillator (AED) usage, and comprehensive emergency action plans (EAPs). Research shows that despite the importance of prompt intervention, the majority of youth club sports programs outside of the school setting lack the training and resources needed to respond effectively to SCA incidents. This study will evaluate the effectiveness of an educational seminar that includes CPR/AED training and EAP simulation exercises in improving participants’ knowledge, skills, and confidence in managing cardiac emergencies. A quasi-experimental …

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 …
