Subcutaneous Emphysema And Pneumomediastinum In Patients With Covid-19 Disease; Case Series From A Tertiary Care Hospital In Pakistan, Sher Sethi, Amber Sabeen Ahmed, Sadaf Hanif, Masooma Aqeel, Ali Bin Sarwar Zubairi

Section of Internal Medicine

Since December 2019, the clinical symptoms of coronavirus disease 2019 (COVID-19) and its complications are evolving. As the number of COVID patients requiring positive pressure ventilation is increasing, so is the incidence of subcutaneous emphysema (SE). We report 10 patients of COVID-19, with SE and pneumomediastinum. The mean age of the patients was 59 ± 8 years (range, 23-75). Majority of them were men (80%), and common symptoms were dyspnoea (100%), fever (80%) and cough (80%). None of them had any underlying lung disorder. All patients had acute respiratory distress syndrome on admission, with a median PaO2/FiO2 ratio of 122.5. …

Statins And Women, Debra Schulte

Rural Health Professions Projects

Low-density lipoprotein (LDL) elevation is a primary risk factor for atherosclerotic cardiovascular problems such as heart disease and stroke. Heart disease is the leading cause of death in the United States and stroke is the fifth leading. Earlier LDL reduction improves morbidity and mortality. Literature indicates fewer women start statin medications compared to men.

Journal Articles: Pulmonary & Critical Care Med

Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease and the traditional variables extracted from computed tomography (CT) images may not be sufficient to describe all the topological features of lung tissues in COPD patients. We employed an unsupervised three-dimensional (3D) convolutional autoencoder (CAE)-feature constructor (FC) deep learning network to learn from CT data and derive tissue pattern-clusters jointly. We then applied exploratory factor analysis (EFA) to discover the unobserved latent traits (factors) among pattern-clusters. CT images at total lung capacity (TLC) and residual volume (RV) of 541 former smokers and 59 healthy non-smokers from the cohort of the SubPopulations …

Journal Articles: Pulmonary & Critical Care Med

BACKGROUND: Although a variety of pathological changes have been described in small airways of patients with COPD, the critical anatomic features determining airflow limitation remain incompletely characterised.

METHODS: We examined lung tissue specimens from 18 non-smokers without chronic lung disease and 55 former smokers with COPD for pathological features of small airways that could contribute to airflow limitation. Morphometric evaluation was performed for epithelial and subepithelial tissue thickness, collagen and elastin content, luminal mucus and radial alveolar attachments. Immune/inflammatory cells were enumerated in airway walls. Quantitative emphysema scoring was performed on chest CT scans.

RESULTS: Small airways from patients with …

Journal Articles: Pulmonary & Critical Care Med

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is the third leading cause of death globally. COPD patients with cachexia or weight loss have increased risk of death independent of body mass index (BMI) and lung function. We tested the hypothesis genetic variation is associated with weight loss in COPD using a genome-wide association study approach.

METHODS: Participants with COPD (N = 4308) from three studies (COPDGene, ECLIPSE, and SPIROMICS) were analysed. Discovery analyses were performed in COPDGene with replication in SPIROMICS and ECLIPSE. In COPDGene, weight loss was defined as self-reported unintentional weight loss > 5% in the past year or low …

Journal Articles: Pulmonary & Critical Care Med

We investigated whether dual bronchodilator therapy (glycopyrrolate/formoterol fumarate; GFF; Bevespi Aerosphere) would increase exercise tolerance during a high-intensity constant work rate exercise test (CWRET) and the relative contributions of dead space ventilation (V_D/V_T) and dynamic hyperinflation (change in inspiratory capacity) to exercise limitation in chronic obstructive pulmonary disease (COPD). In all, 48 patients with COPD (62.9 ± 7.6 yrs; 33 male; GOLD spirometry stage 1/2/3/4, n = 2/35/11/0) performed a randomized, double blind, placebo (PL) controlled, two-period crossover, single-center trial. Gas exchange and inspiratory capacity (IC) were assessed during cycle ergometry at 80% incremental exercise peak …

PURPOSE: Quantitative computed tomography (qCT) imaging-based cluster analysis identified clinically meaningful COPD former-smoker subgroups (clusters) based on cross-sectional data. We aimed to identify progression clusters for former smokers using longitudinal data.

PATIENTS AND METHODS: We selected 472 former smokers from SPIROMICS with a baseline visit and a one-year follow-up visit. A total of 150 qCT imaging-based variables, comprising 75 variables at baseline and their corresponding progression rates, were derived from the respective inspiration and expiration scans of the two visits. The COPD progression clusters identified were then associated with subject demography, clinical variables and biomarkers.

RESULTS: COPD severities at baseline …

Impact Of Bowel Management Guidelines On Documentation And Patient Outcomes In The Intensive Care Unit, Alana Trottier, Paul Blakeslee, Kristiina Hyrkas

Costas T. Lambrew Research Retreat 2021

Introduction

• Bowel management (BM) is an inadvertently overlooked aspect of patient care for critically ill patients who have complex, immediate life-threatening health issues.

• Bowel dysfunction is common with the reported incidence of diarrhea between 3.3%-78% and constipation between 20-83%

• Studies suggest that BM guidelines can standardize care, improve documentation, and impact patient outcomes

• Use of BM guidelines has remained low, probably influenced by clinicians’ resistance to change, resulting in small to moderate improvements and difficulties sustaining new practices

• We anticipated that sustained changes require recognizing clinicians’ current practice, integrating modifications into existing workflow, and engaging …

Precision Drug Delivery For Vancomycin Efficacy And Safety In Critically Ill Patients, Alexander Flannery

Theses and Dissertations--Clinical and Translational Science

Vancomycin is the most commonly prescribed antibiotic for hospitalized patients. Despite this fact and decades of clinical use, clinicians remain challenged to meet dosing targets of this narrow therapeutic index drug as well as minimize the risks of therapy, primarily nephrotoxicity. These concerns are magnified in critically ill patients given their severity. Accordingly, in a series of five clinical studies, we sought to identify optimal methods of vancomycin administration in critically ill patients to maximize efficacy and minimize nephrotoxicity via three techniques: use of continuous versus intermittent infusion, use of first-dose pharmacokinetic calculations to guide dosing, and use of loading …

Potential Perioperative Complications Due To Differences in Timing Of Systemic Heparin Distribution During Ruptured Aneurysm Coiling

Introduction:

In general, systematic heparin anticoagulation is standard in regards to neurovascular intervention. When coiling ruptured aneurysms, many neurointerventionalists have their own protocol as to timing of systemic heparinization. There is ample research and literature reviewing the frequency of perioperative events, predictors and outcomes, as well as the efficacy in the use of anticoagulants and/or antiplatelets before, during, and after neurovascular procedures to prevent adverse outcomes. However, there currently exists a dearth of research in regards to timing of distribution of heparin intraoperatively and …

Management Of Refractory Ventricular Fibrillation With Double Sequential Defibrillation, Kaitlyn A. Brown

Capstone Showcase

Patients experiencing cardiac arrest are treated according to ACLS protocols, however current protocols lack recommendations for the treatment of refractory Ventricular Fibrillation which persists after more than 3 cycles of CPR and defibrillation. One potential intervention for these cases that is being researched is the use of simultaneous or sequential activation of two defibrillators. This literature review analyzed the results of several studies to determine if double sequential defibrillation (DSD) is a viable treatment to achieve return of spontaneous circulation (ROSC) and improved patient survival. The results of the studies were mixed with some showing positive outcomes, and others showing …

Developing An End-Of-Life Discussion Protocols, James Hawley

Rural Health Professions Projects

End of life (EOL) issues are far too often addressed reactively in Emergency Departments when patients can no longer express their wishes. This scenario can result in unwanted futile care, increased healthcare costs, and emotional hardships for family and healthcare workers. The purpose of this quality improvement project was to implement a provider-patient communication protocol that would shift advanced directive conversations proactively back into the local rural primary care setting.

Neurally Adjusted Ventilatory Assist: Summation Of The Safety Proofs And Benefits, Landry Carneal

Williams Honors College, Honors Research Projects

Neurally Adjusted Ventilatory Assist (NAVA) is a mode of ventilation that is triggered by neither flow nor pressure but by the electrical activity of the diaphragm (Stein & Firestone, 2018, p. 227). NAVA puts ventilatory control into the hands of the patient and is often used in neonates who are more challenging to ventilate. Medical practitioners, however, are skeptical to put this mode of ventilation into practice with fear that neonates are neither strong enough nor capable to manage their own respiratory efforts without hypoventilation or damage to the lungs (Lubarsky et al., 2020, p. 3). Research shows that despite …

Effectiveness Of Point-Of-Care Ultrasound Education For Advanced Practice Providers, Nicole Brumfield

DNP Projects

Abstract

Background: Provider shortages and demands for inpatient providers have led to an increase in the utilization of Advanced Practice Providers (APPs). The increased use and specialization of APPs has brought attention to education and skills that have been instituted for other provider types but remains missing from the APP curricula. One such example is point-of-care ultrasound (POCUS) education. This technology and skill set have been shown to enhance clinical skills, confidence levels, and provide useful information for the provider to enhance clinical decision making for the patient.

Purpose: The purpose of this project was to evaluate the effectiveness of …
