Background: Extracorporeal membrane oxygenation (ECMO) is a form of temporary cardiopulmonary support used in critically ill pediatric patients when conventional therapies fail, yet survival to discharge remains only ~50% nationwide. Prior studies have identified candidate mortality predictors and developed basic risk scores, but these models have limited accuracy and are often derived from registry-level or narrowly defined …

Pseudomonas Aeruginosa Exoenzyme Y Enzymatic Activity Inhibits Exoenzyme S-Induced Caspase Activation But Not Cytotoxicity In Pulmonary Microvascular Endothelial Cells, Connor Holm

Honors Theses

Pseudomonas aeruginosa (P. aeruginosa) is the most common cause of ventilator-associated pneumonia in intensive care unit patients. P. aeruginosa utilizes a type III secretion system that injects exoenzymes U, S, T, and/or Y into the host cell cytosol. A majority of clinically isolated P. aeruginosa strains express ExoY often in combination with ExoU and ExoT, or ExoS and ExoT. Host signaling mechanisms in response to intoxication with individual exoenzymes have been extensively studied, yet little is known about host cell response to co-intoxication. In this study, pulmonary microvascular endothelial cells (PMVECs) were infected with P. aeruginosa strains expressing different combinations …

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 …

Parasympathetic Activity And Bronchial Hyperresponsiveness In Athletes, Audrey Badza

The Downtown Review: An Interdisciplinary Journal Written and Peer-Reviewed by Mandel Honors College Students at Cleveland State University

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, …

Atrial Thrombus In A Premature Newborn Following Cardio-Pulmonary Resuscitation, Syed Rehan Ali, Shakeel Ahmed, Nadeem Aslam, Heeramani Lohana

Department of Paediatrics and Child Health

Critically ill newborns, whether term or preterm, are at great risk for developing symptomatic thromboembolic disease. Comorbidities like inflammation, DIC, fluctuations in cardiac output, congenital heart disease, as well as central venous or arterial catheters, are the predisposing risk factors. Clinically symptomatic or asymptomatic cases are usually picked up by echocardiography, usually done for other indications. Management usually comprises of observation, heparin therapy, thrombo-embolectomy, and catheter directed revascularization. We present a case of premature neonate who developed thrombus at inter-atrial septum as a possible consequence of cardiopulmonary resuscitation, detected by echocardiography. Conversely, there is always a possibility of paradoxical emboli …
