Evidence of the circulation of hepatitis A virus, subgenotype IA, in environmental samples from Antioquia, Colombia.

Introduction: Hepatitis A virus (HAV) is an important pathogen, typically transmitted via the faecal-oral route. The epidemiology of the infection is directly related to drinking water access and adequate disposal of sewage water. 

Objective: To determine the presence and identify the genotype of HAV in environmental samples from eight municipalities and two villages in Antioquia, northwestern Colombia.

Randomized trials of PCIs versus CABG surgery: why coronary stenting should remain the first choice of revascularization in non-diabetic patients and why the controversy is still present in diabetics.

Knowing the best revascularization option for diabetic patients with multiple vessel disease is a challenge without a definitive answer. There have been several randomized clinical trials and subsequent meta-analyses comparing current available technology trying to reach an exhaustive conclusion; comparisons between coronary artery bypass grafts and bare-metal stents, coronary artery bypass grafts and first generation drug-eluting stents and, most recently, first generation versus latest generation drug-eluting stents generated some interesting results. Information provided by pooled data from some of the most important randomized clinical cardiology trials from the last two decades have produced surprising results.
