Pseudomonas fluorescens CRBSI outbreak: complying with the standardization of invasive procedures is a step ahead in the fight against antimicrobial resistance.

In the healthcare sector, the implementation of standardized procedures, such as those commonly employed in franchises to ensure consistent quality, remains underprioritized. Within this framework, we focus on the importance of standardized central venous catheter (CVC) insertion procedures to prevent healthcare-associated outbreaks. While antimicrobial resistance (AMR) may still not be the most prevalent problem in some institutions, its increasing significance certainly underlines the urgency of infection prevention.

SARS-CoV-2 infection in health care workers during the first 2-years of the pandemic at a cancer hospital in Mexico.

Background: Health care workers (HCWs) are occupationally exposed to severe acute respiratory syndrome coronavirus (SARS-CoV-2). This study aimed to characterize COVID-19 in HCWs at an oncology hospital in Mexico City over 2-years, identify factors associated with severity, and establish transmission dynamics.

Methods: This retrospective study included HCWs with confirmed COVID-19.

Microbiology and clinical characteristics of viridans group streptococci in patients with cancer.

This study assessed the microbiology, clinical syndromes, and outcomes of oncologic patients with viridans group streptococci isolated from blood cultures between January 1st, 2013 and December 31st, 2016 in a referral hospital in Mexico using the Bruker MALDI Biotyper. Antimicrobial sensitivity was determined using BD Phoenix 100 according to CLSI M100 standards. Clinical information was obtained from medical records and descriptive analysis was performed.

[Involvement of matrix metalloproteinases in acute coronary syndrome (ACS)].

Matrix metalloproteinases (MMP) are enzymes that degrade extracellular matrix (ECM) proteins and regulate both their accumulation and composition. The MMP are involved in the atherosclerotic process since they contribute to the formation of the plaque and its subsequent rupture. This last step triggers the myocardial ischemia that will be clinically reflected as an acute coronary syndrome (ACS).
