Urinary catheterization of patients with acute heart failure in a hospital emergency department: a factor associated with prognosis.

Objectives: To analyze whether urinary catheterization in a hospital emergency department (ED) affects short-term prognosis in patients with acute heart failure (AHF).

Material And Methods: We prospectively recorded baseline and other clinical data in a consecutive cohort of ED patients treated for AHF. Crude and adjusted associations were calculated between catheterization and a primary composite outcome (30-day readmission for AHF and/or death) and secondary outcomes (in-hospital mortality, urinary tract infection [UTI], and duration of hospital stay.

Women occupying preferential authorship positions for articles in the journal Emergencias: an analysis of authorship during the last decade.

Objectives: To analyze gender disparity in scientific productivity reflected by the authorship of articles in the journal Emergencias over the past decade.

Material And Methods: Retrospective longitudinal study. We included articles in all issues published between January 2011 and December 2020, analyzing the number of authors, their gender, article type, year of publication, and preferential authorship credit (first author, corresponding author, and last author positioning).

Early Treatment of Acute Myocardial Infarction with Melatonin: Effects on MMP-9 and Adverse Cardiac Events.

Background: Matrix metalloproteinase-9 (MMP-9) is crucial in tissue remodeling after an adverse cardiac event. In experimental studies, melatonin has been found to attenuate MMP-9 activation. The present study assessed the effects of systemic melatonin administration on the prognosis of patients with acute myocardial infarction (AMI) successfully treated with primary percutaneous coronary intervention, and to examine the effects on MMP-9 levels.
