Role of rectal colonization by third-generation cephalosporin-resistant Enterobacterales on the risk of surgical site infection after hepato-pancreato-biliary surgery.

Unlabelled: The impact of third-generation cephalosporin-resistant Enterobacterales (3GCR-E) rectal colonization in the development of subsequent infection after surgery is controversial. In particular, there is a lack of data in the context of hepato-pancreato-biliary (HPB) surgery. The objective of this study was to assess the prevalence of 3GCR-E intestinal carriage among patients undergoing elective HPB resection surgery and its impact on the incidence and etiology of surgical site infections (SSIs).

Association of microbiological factors with mortality in Escherichia coli bacteraemia presenting with sepsis/septic shock: a prospective cohort study.

Objectives: This study aimed to determine the association of Escherichia coli microbiological factors with 30-day mortality in patients with bloodstream infection (BSI) presenting with a dysregulated response to infection (i.e. sepsis or septic shock).

MIC of amoxicillin/clavulanate according to CLSI and EUCAST: discrepancies and clinical impact in patients with bloodstream infections due to Enterobacteriaceae.

Objectives: To compare results of amoxicillin/clavulanate susceptibility testing using CLSI and EUCAST methodologies and to evaluate their impact on outcome in patients with bacteraemia caused by Enterobacteriaceae.

Patients And Methods: A prospective observational cohort study was conducted in 13 Spanish hospitals. Patients with bacteraemia due to Enterobacteriaceae who received empirical intravenous amoxicillin/clavulanate treatment for at least 48 h were included.

[Epidemiology, risk factors and in vitro susceptibility in candidaemia due to non-Candida albicans species].

Background: Invasive fungal infection (IFI) has increased in recent years due to there being a greater number of risk factors. IFI caused by Candida is the most frequent, and although Candida albicans is the most isolated species, there is currently a decrease of C. albicans and an increase of other species of the genus.

[Microbiological aspects of the cryptococcosis in the post-HAART era].

Cryptococcosis is a mycoses that increased considerably with the AIDS epidemic. However, with the introduction in the late 90's of the highly active antiretroviral therapy (HAART), this incidence has significantly decreased, especially in developed countries, in contrast with that of developing countries. The introduction of HAART not only has affected the incidence rate, but also the clinical presentation as a consequence of the immune recovery of the host, leading to the description of the so called immune reconstitution inflammatory syndrome.
