Infective endocarditis surgery timing.

Background: The optimum timing of surgical intervention in complicated left-sided infective endocarditis is not well established. Guidelines from various professional societies are not consistent regarding this. Data concerning this remains limited with conflicting results.

TAVR vs balloon aortic valvotomy for severe aortic stenosis and cardiogenic shock: An insight from the National Inpatient Sample database.

Background: Severe Aortic stenosis (AS) complicated by cardiogenic shock (CS) represents a grave clinical condition with limited treatment options. Evidence from small observation studies favors that Transcatheter Aortic Valve Replacement (TAVR) might be a feasible option in these patients in contrast to emergent Balloon Aortic Valvuloplasty (BAV) which is associated with very high short and long-term mortality.

Methods: 11,405 hospitalizations with severe AS complicated by CS between 2016 and 2020 were identified using the National Inpatient Sample (NIS) Database, and patients were then stratified according to whether they received TAVR or BAV.

Myocardial injury in hospitalized COVID-19 patients: a retrospective study, systematic review, and meta-analysis.

Introduction: The majority of studies evaluating the effect of myocardial injury on the survival of COVID-19 patients have been performed outside of the United States (U.S.).

Posterolateral intertransverse lumbar arthrodesis in the New Zealand White rabbit model: I. Surgical anatomy.

Background Context: The New Zealand White rabbit model for posterolateral lumbar fusion is commonly used for spinal fusion research. However, the high rate of animal morbidity and mortality associated with the model makes experimentation inefficient and can lead to faulty data analysis. Operative complications are in part the result of inadequate knowledge of normal rabbit lumbar spine anatomy.
