A rare case of May-Thurner syndrome due to external compression of the right and left common iliac veins.

May-Thurner syndrome, also known as external iliac compression syndrome, is a rare but commonly underdiagnosed cause of asymmetric lower extremity edema. Here we describe a case of May-Thurner syndrome owing to external compression of the right and left common iliac veins presenting as chronic worsening asymmetric right greater than left lower extremity edema. Initial etiology workup was unremarkable, and further diagnostics revealed compression of the right common iliac vein at the bifurcation of the right common iliac artery between the right external and internal iliac arteries with concomitant compression of the left common iliac vein.

Characteristic adverse events with intra-aortic balloon pumps: An analysis of the U.S. Food and Drug Administration MAUDE database from 2016 to 2021.

Introduction: The United States Food and Drug Administration Manufacturer and User Facility Device Experience (MAUDE) dataset represents a unique source for post-market surveillance data on adverse events (AE). An analysis of AE with percutaneous mechanical circulatory support (pMCS) devices has previously been reported specifically for microaxial flow pumps. The characteristic AE for the intra-aortic balloon pump (IABP) have not been similarly analyzed or reported.

A Rare Case of Radiation-Associated Aortic and Mitral Valve Stenosis Treated With Transcatheter Valve Replacements.

Radiation therapy is the standard of care for achieving cure for many thoracic malignancies, but it can result in long-term cardiovascular sequelae such as valve disease. We describe a rare case of severe aortic and mitral stenosis due to prior radiation therapy for giant cell tumor treated successfully with percutaneous aortic and off-label mitral valve replacements.

Plaque progression assessed by a novel semi-automated quantitative plaque software on coronary computed tomography angiography between diabetes and non-diabetes patients: A propensity-score matching study.

Background And Aims: We aimed at investigating whether diabetes is associated with progression in coronary plaque components.

Methods: We identified 142 study subjects undergoing serial coronary computed tomography angiography. The resulting propensity score was applied 1:1 to match diabetic patients to non-diabetic patients for clinical risk factors, prior coronary stenting, coronary artery calcium (CAC) score and the serial scan interval, resulting in the 71 diabetes and 71 non-diabetes patients.

Nonadditive indirect effects of group genetic diversity on larval viability in Drosophila melanogaster imply key role of maternal decision-making.

Genetic variation can have important consequences for populations: high population genetic diversity is typically associated with ecological success. Some mechanisms that account for these benefits assume that local social groups with high genetic diversity are more successful than low-diversity groups. At the same time, active decision-making by individuals can influence group genetic diversity.
