Spontaneous Large Volume Hemothorax Managed With A Small-Bore Chest Tube, Moiz Salahuddin, Samia Ayub

Department of Medicine

A 67-year-old male with metastatic lung cancer presented with acute shortness of breath and increasing oxygen requirements. He had a decreasing hemoglobin for which he required red blood cell transfusions. His chest x-ray showed near complete white-out of the left lung. Bedside ultrasound (Handheld Sonostar C4PL) showed a large pleural effusion with swirling echogenic material suggestive of plankton sign. The pleural effusion was aspirated and showed frank blood, after which a small-bore chest tube (SBCT) was inserted. A total of 3200ml of blood was drained with the SBCT. There was complete clearance of the pleural space, and no further blood …

Variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have caused successive global waves of infection. These variants, with multiple mutations in the spike protein, are thought to facilitate escape from natural and vaccine-induced immunity and often increase in affinity for ACE2. The latest variant to cause concern is BA.2.75, identified in India where it is now the dominant strain, with evidence of wider dissemination. BA.2.75 is derived from BA.2 and contains four additional mutations in the receptor-binding domain (RBD). Here, we perform an antigenic and biophysical characterization of BA.2.75, revealing an interesting balance between humoral evasion and ACE2 receptor …

Implementation Of Mrsa Nasal Swabs As An Antimicrobial Stewardship Intervention To Decrease Anti-Mrsa Therapy In Covid-19 Infection, Alaina Dekerlegand, Emily Johnston, Britney Mellor, Melanie Rae Schrack, Catherine O’Neal

School of Medicine Faculty Publications

In the early stages of treating patients with SARS-CoV-2, limited information was available to guide antimicrobial stewardship interventions. The COVID-19 Task Force and Antimicrobial Stewardship Committee, at a 988-bed academic medical center, implemented the use of methicillin-resistant Staphylococcus aureus (MRSA) nasal swab polymerase chain reaction (PCR) testing to assist with the de-escalation of anti-MRSA therapy in patients with suspected superimposed bacterial pneumonia in COVID-19. A retrospective study was conducted to evaluate the impact of MRSA nasal swab PCR testing on the rate of anti-MRSA therapy between 13 April 2020 and 26 July 2020. A total of 122 patients were included …

Inhibition Of Ribosome Assembly Factor Pno1 By Crispr/Cas9 Technique Suppresses Lung Adenocarcinoma And Notch Pathway: Clinical Application, Sanjit K. Roy, Shivam Srivastava, Andrew Hancock, Anju Shrivastava, Jason Morvant, Sharmila Shankar, Rakesh K. Srivastava

School of Medicine Faculty Publications

Growth is crucially controlled by the functional ribosomes available in cells. To meet the enhanced energy demand, cancer cells re-wire and increase their ribosome biogenesis. The RNA-binding protein PNO1, a ribosome assembly factor, plays an essential role in ribosome biogenesis. The purpose of this study was to examine whether PNO1 can be used as a biomarker for lung adenocarcinoma and also examine the molecular mechanisms by which PNO1 knockdown by CRISPR/Cas9 inhibited growth and epithelial–mesenchymal transition (EMT). The expression of PNO1 was significantly higher in lung adenocarcinoma compared to normal lung tissues. PNO1 expression in lung adenocarcinoma patients increased with …

Background While COVID-19 vaccines reduce adverse outcomes, post-vaccination SARS-CoV-2 infection remains problematic. We sought to identify community factors impacting risk for breakthrough infections (BTI) among fully vaccinated persons by rurality. Methods We conducted a retrospective cohort study of US adults sampled between January 1 and December 20, 2021, from the National COVID Cohort Collaborative (N3C). Using Kaplan-Meier and Cox-Proportional Hazards models adjusted for demographic differences and comorbid conditions, we assessed impact of rurality, county vaccine hesitancy, and county vaccination rates on risk of BTI over 180 days following two mRNA COVID-19 vaccinations between January 1 and September 21, 2021. Additionally, …

Phase 1a Clinical Study For Q-Griffithsin Intranasal Spray For Prevention Of Coronavirus, Megan Bezold, Kenneth Palmer, Nobuyuki Matoba, Elizabeth Cash

Posters-at-the-Capitol

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a highly transmissible virus that causes acute respiratory disease with possible long-term complications, known as coronavirus disease 2019 (COVID-19). Griffithsin (GRFT; including the oxidation-resistant variant Q-GRFT used in this study) is an algal carbohydrate-binding protein exhibiting antiviral effects against many enveloped viruses, including all major variants of SARS- CoV-2 reported to date. Q-GRFT has been recombinantly manufactured in Nicotiana benthamiana plants, thoroughly purified, and formulated as an intranasal spray designed to be developed as a non-vaccine broad-spectrum prophylactic product for acute use. This is the first-in-human, randomized, double-blind, placebo-controlled study. The …

Implementation Of A Smoking Cessation Program In A Multidisciplinary Clinic, Lori Prewitt Moore, Shannon Harris

DNP Manuscripts

Tobacco use remains the solitary, most preventable cause of death and secondary disease among patients in the United States (US). Health-related smoking costs are in an excess of $300 billion yearly (CDC, 2018). Addressing this global, public health concern is vital in order to attempt to reduce unnecessary smoking-related comorbid conditions and death. This project is important to scholarly nursing practice in order to reduce smoking-related Chronic Obstructive Pulmonary Disease (COPD) exacerbations, reduce carbon monoxide (CO) levels, and reduce dyspnea on exertion (DOE) among current primary care smokers. The expectations of this project are for the doctoral of nursing practice …

Outcomes Of Patients With Copd During The Covid Pandemic, Jacob Hentges, Julia Fashner

East Florida Division GME Research Day 2023

A scoping review of COVID-19's impact on healthcare delivery and health outcomes found disruptions in care delivery and a shift towards telemedicine(1). Another study found no significant change in the length of stay for patients admitted to the hospital for COPD exacerbation during the pandemic period compared to the pre-pandemic period(2).

We conducted a secondary analysis of HCA Florida St. Lucie Hospital data to compare the outcomes of patients with COPD before (Jan 2018 – Feb 2020) and during the COVID-19 pandemic (March 2020 – Dec 2021). The data included patients aged over 18 years who were diagnosed with COPD …

Agricultural Dust Derived Bacterial Extracellular Vesicle Mediated Inflammation Is Attenuated By Dha, Art J. Heires, Derrick R. Samuelson, Daniel Villageliu, Tara M. Nordgren, Debra J. Romberger

Journal Articles: Pulmonary & Critical Care Med

Dietary long-chain omega-3 polyunsaturated fatty acids (n-3 PUFA) and their pro-resolving metabolites are protective against atherosclerotic disease, and ameliorate systemic inflammatory conditions including lupus erythematosus, psoriasis, and bronchial asthma. Organic bioaerosol inhalation is a common and injurious hazard associated with agricultural occupations such as work in swine concentrated animal feeding operations (CAFOs) and is known to increase the risk for developing respiratory conditions such as asthma and COPD. Nearly all cells secrete membrane-bound vesicles (extracellular vesicles, EVs) that have the capacity to transmit protein, nucleic acid, and lipid signaling mediators between cells. Using a polymer-based isolation technique (ExoQuick, PEG) followed …

Managing Recurrent Delayed Pleural Effusion Post Rib Fracture In An Elderly Female, Yaseen Ramadan, Fnu Swatisikta, Mushfeka Baker Golawala

East Florida Division GME Research Day 2023

INTRODUCTION Delayed pleural effusion (DPL) post rib fracture is a lesser known and not adequately studied entity. DPL is associated with increased hospital/ICU length of stay (LOS) and poorer disposition at discharge. Some case series have reported incidence as high as 40.8 % making it a clinically significant complication to watch for.

CASE An elderly female presented to the ED after a mechanical fall leading to right side fractured ribs (5th to 9th rib posteriorly) and pneumothorax. Patient was hypoxic in ER and an ICD was placed. Trauma series showed right pulmonary contusion but no hemothorax or any other injury. …
