Changes in Antimicrobial Resistance and Etiology of Blood Culture Isolates: Results of a Decade (2010-2019) of Surveillance in a Northern Region of Colombia.

Background: Bloodstream infections (BSI) are important causes of morbidity and mortality worldwide. Antimicrobial surveillance is essential for identifying emerging resistance and generating empirical treatment guides, the purpose of this study is to analyze trends in antimicrobial susceptibility of BSI from 2010 to 2019 in healthcare institutions from Medellin and nearby towns in Colombia.

Methods: A Whonet database was analyzed from the GERMEN antimicrobial surveillance network; frequency and antibiotic susceptibility trends were calculated on more frequent microorganisms using Mann Kendall and Sen's Slope Estimator Test.

Left bundle branch block as equivalent of ST-segment elevation myocardial infarction: when yes, when not?

A new or presumably new left bundle branch block along with ischemic symptoms has traditionally been considered an electrocardiographic equivalent of ST-segment elevation myocardial infarction, which should be brought to emergent reperfusion. However, several criteria have been proposed for its definition, but none has reached out an optimal diagnostic yield. Below we detail these criteria, their main problems and the advantages they have shown.

AVR ST-segment elevation as predictor of three-vessel disease in non-ST-segment elevation acute coronary syndrome.

Electrocardiogram is a useful tool for the diagnosis of acute coronary syndrome. In recent years, ST-segment changes in aVR have been shown to provide valuable information about coronary anatomy and early risk stratification of this condition.
