Thrombus vs Tumor: Use of AngioVac in a RV Mass.

This paper present a challenging case of a right ventricular mass in a patient who was at high surgical risk for open removal. The minimally invasive AngioVac device has been used with a successful 50% reduction in mass burden. This report illustrates AngioVac as a safe alternative to invasive surgery.

Myocardial mechanics of percutaneous intramyocardial septal radiofrequency ablation.

Objective: Echocardiography-guided Percutaneous IntraMyocardial Septal Radiofrequency Ablation (PIMSRA, Liwen procedure) is a novel treatment option for hypertrophic obstructive cardiomyopathy (HOCM). The impact of PIMSRA on myocardial mechanics is unknown.

Methods: Between October 2016 and June 2019, PIMSRA and 3-dimentional speckle tracking echocardiography were performed in 82 patients.

Thoracic Aortic Aneurysm: A Clinical Review.

Thoracic aortic aneurysms are common. Most thoracic aortic aneurysms are degenerative. However, some are associated with connective tissue disorders, bicuspid aortic valves, or familial/genetic predisposition.

Racial and insurance disparities among patients presenting with chest pain in the US: 2009-2015.

Background: Nationally representative studies have shown significant racial and socioeconomic disparities in the triage and diagnostic evaluation of patients presenting to the emergency department (ED) with chest pain. However, these studies were conducted over a decade ago and have not been updated amidst growing awareness of healthcare disparities.

Objective: We aimed to reevaluate the effect of race and insurance type on triage acuity and diagnostic testing to assess if these disparities persist.

Qualitative synthesis and systematic review of otolaryngology in undergraduate medical education.

Objective: Although 25% of primary care complaints are otolaryngology related, otolaryngology instruction is not required in most medical schools. Our aim was to systematically review existing literature on the inclusion of otolaryngology in undergraduate medical education.

Chemistry of ring-substituted 4-(benzothiazol-2-yl)phenylnitrenium ions from antitumor 2-(4-aminophenyl)benzothiazoles.

Ring-substituted derivatives of 2-(4-aminophenyl)benzothiazole, 1a, 1b-g, are under development as antitumor agents. One derivative, 1f, has reached phase 1 clinical trials as the prodrug 2f, Phortress (NSC 710305). These amines are activated by CYP450 1A1, apparently into hydroxylamines 8a-g that are likely metabolized into esters that ionize into nitrenium ions responsible for cellular damage.
