Virtual screening: hope, hype, and the fine line in between.

Introduction: Technological advancements in virtual screening (VS) have rapidly accelerated its application in drug discovery, as reflected by the exponential growth in VS-related publications. However, a significant gap remains between the volume of computational predictions and their experimental validation. This discrepancy has led to a rise in the number of unverified 'claimed' hits which impedes the drug discovery efforts.

Total autologous reconstruction of the right and left ventricular outflow tracts: the case for the modified Ross-Ozaki procedure.

The Ross procedure continues to be the best procedure to address unrepairable aortic valve pathology, especially in young adults. The Achilles heel of this procedure has been aortic root dilation and the potential need for a reoperation that may be associated with slightly increased risks in addition to the need for intervention on the pulmonary outflow tract. Modifying the Ross procedure by autograft inclusion inside a Dacron graft seems to have the potential advantage of stabilizing the autograft diameter, which may be associated with improved durability and decrease the need for future intervention.

Intrapericardial Corticosteroids and Colchicine Prevent Pericarditis and Atrial Fibrillation After Epicardial Ablation of Ventricular Arrhythmias.

Background: Postprocedural pericarditis (PP) can occur in up to 29.4% of patients undergoing epicardial catheter ablation of ventricular tachycardia (VT). Despite several proposed strategies to mitigate this adverse outcome, rates of PP and pericarditic pain remain high.

Endoscopic management of bleeding ectopic varices: multicentric retrospective case series.

Introduction: Portal hypertension is a common complication of liver cirrhosis. Varices are dilated collaterals that develop as a result of portal hypertension at the level of the porto-systemic connections and can cause a shift in the blood flow from high to low pressure. Common locations for porto-systemic shunts are the lower oesophagus and the gastric fundus.
