Development And Implementation Of An Evidence Based Practice Guideline Related To The Management Of Adult Angioedema, Megan Przybysz

Doctor of Nursing Practice Scholarly Projects

Angioedema (AE) is a potentially life-threatening medical condition that occurs with a higher frequency than medical providers may expect, with the emergency department (ED) serving as the usual first point of medical contact for patients. Any hesitation in recognizing AE or inconsideration of the disease process in differential diagnoses may lead to a dangerous delay of care. Due to the potential rapid progression of airway obstruction in AE, inexperienced providers should not attempt intubation, instead deferring to providers experienced in alternative airway techniques (i.e., anesthesia providers). The primary goal of this project is to develop an evidencebased practice guideline for …

A Multiple-Site Case Inquiry To Identify The Attributes Of Socio-Academic Culture In Successful Entry-To-Practice Respiratory Therapy Programs, Thomas D. Jones

Doctor of Education (Ed.D)

Background: Organizational structure and culture have been explored extensively in higher education. Nonacademic factors influence student engagement, motivation, and success. Research describing socio-academic culture in health professions programs is limited. Achievement of fundamental social-emotional learning (SEL) competencies empowers students to learn and achieve educational goals. SEL has not been established as a theoretical framework in health professions education. SEL competencies closely align with respiratory therapy (RT) learner needs and essential professional skills. Attributes of socio-academic culture in successful RT programs and their impact on student success are unknown. Objective: To identify the attributes of socio-academic culture in successful entry-to-practice respiratory …

A Case Report And Review On The Anesthetic Considerations Of Anterior Mediastinal Masses, Carter A. Schulz, Joshua D. Mohs, Andrew M. Reuter

Aesculapius Journal (Health Sciences & Medicine)

Case summary: A 15-year-old female presented with chest pain, dyspnea, and weight loss. A chest X-ray and subsequent CT scan revealed a large anterior mediastinal mass with cervical lymphadenopathy and pericardial effusion. Two biopsies under general anesthesia were performed, with the latter confirming classic Hodgkin lymphoma, nodular sclerosis subtype.

Discussion: This case underscores the significant clinical challenges posed by anterior mediastinal masses due to their proximity to vital cardiovascular and respiratory structures. Physiologic changes during general anesthesia can exacerbate these challenges. Preoperative assessment, including imaging and symptom evaluation, is crucial to guide operative planning. It is key to individualize the …

Several barriers to screening exist including lack of knowledge and awareness among patients regarding lung cancer screening. By increasing knowledge, at risk patients can take the necessary steps to decrease incidence of late stage diagnoses.

Purpose: The purpose of this project was to evaluate patients’ knowledge of lung cancer screening and referral and screening rates before and after one-on-one patient education.

Methods: This was a quality improvement project that used …

Hsp70 Is A Critical Regulator Of Hsp90 Inhibitor's Effectiveness In Preventing Hcl-Induced Chronic Lung Injury And Pulmonary Fibrosis, Ruben M. L. Colunga Biancatelli, Pavel A. Solopov, Tierney Day, Betsy Gregory, Michael Osei-Nkansah, Christiana Dimitropoulou, John D. Catravas

Bioelectrics Publications

Exposure to hydrochloric acid (HCl) can provoke acute and chronic lung injury. Because of its extensive production for industrial use, frequent accidental exposures occur, making HCl one of the top five chemicals causing inhalation injuries. There are no Food and Drug Administration (FDA)-approved treatments for HCl exposure. Heat shock protein 90 (HSP90) inhibitors modulate transforming growth factor-β (TGF-β) signaling and the development of chemical-induced pulmonary fibrosis. However, little is known on the role of Heat Shock Protein 70 (HSP70) during injury and treatment with HSP90 inhibitors. We hypothesized that administration of geranylgeranyl-acetone (GGA), an HSP70 inducer, or gefitinib (GFT), an …

Methods; In this observational study we analysed deaths occurring between Dec 16, 2016, and Dec 31, 2022, in the CHAMPS Network across six countries in sub-Saharan Africa (Ethiopia, Kenya, Mali, Mozambique, Sierra Leone, and …

Parasympathetic Activity And Bronchial Hyperresponsiveness In Athletes, Audrey Badza

The Downtown Review

Bronchial hyperresponsiveness (BHR) is a term used to describe the bronchial constriction response to environmental stimuli. BHR is increasingly common in endurance athletes due to increased exposure to some stimuli. The purpose of this review is to evaluate Stang et al.'s (2016) article, "Parasympathetic Activity and Bronchial Hyperresponsiveness in Athletes" and discuss the significance of their results. The results concluded that BHR is related to the parasympathetic activity of the heart rather than the pupils. The study concluded that there is an association between BHR and parasympathetic activity of the heart, methacholine is associated with BHR and cardiac vagal activity, …

Loss Of Cftr Function In Macrophages Alters The Cell Transcriptional Program And Delays Lung Resolution Of Inflammation, Dianne Wellems, Yawen Hu, Scott Jennings, Guoshun Wang

School of Graduate Studies Faculty Publications

Cystic fibrosis (CF) is an autosomal recessive genetic disorder caused by mutations in the CF Transmembrane-conductance Regulator (CFTR) gene. The most severe pathologies of CF occur in the lung, manifesting as chronic bacterial infection, persistent neutrophilic inflammation, and mucopurulent airway obstruction. Despite increasing knowledge of the CF primary defect and the resulting clinical sequelae, the relationship between the CFTR loss of function and the neutrophilic inflammation remains incompletely understood. Here, we report that loss of CFTR function in macrophages causes extended lung inflammation. After intratracheal inoculation with Pseudomonas aeruginosa, mice with a macrophage-specific Cftr-knockout (Mac-CF) were able to mount an …

Bryner, Adam D. Devore, Jacob N. Schroder, Chetan B. Patel, Sudarshan Rajagopal, Svati H. Shah, Carmelo A. Milano, Inspire-Flo Investigators

Respiratory Therapy Faculty Publications and Presentations

Background: Right ventricular failure (RVF) is a leading driver of morbidity and death after major cardiac surgery for advanced heart failure, including orthotopic heart transplantation and left ventricular assist device implantation. Inhaled pulmonary-selective vasodilators, such as inhaled epoprostenol (iEPO) and nitric oxide (iNO), are essential therapeutics for the prevention and medical management of postoperative RVF. However, there is limited evidence from clinical trials to guide agent selection despite the significant cost considerations of iNO therapy.

Methods: In this double-blind trial, participants were stratified by assigned surgery and key preoperative prognostic features, then randomized to continuously receive either iEPO or iNO …

Understanding Our Airways: How Lung Structure And Function Is Impacted By Respiratory Infections And Immune Responses, Katherine Coll

McNair Research Journal SJSU

Understanding the underlying functions and interplaying systems that make up the respiratory system is a crucial step in the research and development of treatments for respiratory illnesses. In this literature review, I explore the complex biochemical processes that occur in the pulmonary epithelium and endothelium. As epithelial and endothelial cells serve a multitude of functions such as host protection and nutrient regulation, discussing the interplay between these cells and intercellular junctions and their immediate impact on the respiratory system is essential to understanding the impact of respiratory dysfunctions and diseases. This review further examines the different types of intercellular junctions …

Preparing For The Unexpected: Recognizing A Tortuous Thoracic Aorta During Ultrasound-Guided Thoracentesis, Michael Choi, Jessica Roettger, Christopher J. Smith

Graduate Medical Education Research Journal

Ultrasound-guidance has become the standard of care for bedside thoracentesis. This manuscript describes the importance of utilizing point-of-care-ultrasound (POCUS) and color Doppler in avoiding an unusual, but potentially catastrophic aortic puncture during thoracentesis. The case describes a 70 year-old man who presented with one week of shortness of breath. He was found to have a large left-sided pleural effusion on imaging studies. During a bedside POCUS examination, he was found to have a hyperechoic linear structure in his posterior left hemithorax. Ultrasound application of color Doppler revealed a pulsatile flow, confirming visualization of the aorta. The site of needle insertion …

Case Report: Cavitary Pneumonia In A 28 Year Old Male, Dan Zaayenga, Katelyn Courtney

Rowan-Virtua Research Day

Cavitary pneumonia can be caused by several different mechanisms. Such causes include suppurative necrosis (pyogenic lung abscess), caseous necrosis (tuberculosis), ischemic necrosis (pulmonary infarction) cystic dilatation of lung structures (ball value obstruction and Pneumocystis pneumonia) as well as malignant processes. Causes are subject to both environmental factors and host susceptibility. The most common cause of infectious process is tuberculosis with its propensity to cause extensive caseous necrosis. The potential for secondary infection after an individual develops a cavitary pneumonia is also great as it provides a shelter for various pathogens the flourish in an environment otherwise usually well-guarded by host …

Uh-02 A Case Report Of The Potential Link Between Pulmonary Fibrosis And Diabetes Mellitus, Bryson T. Rose, Isabella Nielson, Nnenna Igwe

SC Upstate Research Symposium

Pulmonary fibrosis is a chronic lung disease that is characterized by the progressive and irreversible scarring of the lung tissue. This scarring greatly diminishes the efficiency of pulmonary function. After being diagnosed with pulmonary fibrosis, patients live, on average, only three to five years. Diabetes mellitus is known to damage the tissue and blood vessels in organs such as the heart and kidneys due to increased intravascular pressure.

According to recent research, diabetes mellitus has also been linked to similar damage in the lungs. Additionally, a 2021 meta-analysis and systematic review of idiopathic pulmonary fibrosis suggests an association between diabetes …

Novel 129xe Magnetic Resonance Imaging And Spectroscopy Measurements Of Pulmonary Gas-Exchange, Alexander M. Matheson

Electronic Thesis and Dissertation Repository

Gas-exchange is the primary function of the lungs and involves removing carbon dioxide from the body and exchanging it within the alveoli for inhaled oxygen. Several different pulmonary, cardiac and cardiovascular abnormalities have negative effects on pulmonary gas-exchange. Unfortunately, clinical tests do not always pinpoint the problem; sensitive and specific measurements are needed to probe the individual components participating in gas-exchange for a better understanding of pathophysiology, disease progression and response to therapy.

In vivo Xenon-129 gas-exchange magnetic resonance imaging (¹²⁹Xe gas-exchange MRI) has the potential to overcome these challenges. When participants inhale hyperpolarized ¹²⁹Xe gas, it …
