Gut barrier dysfunction and the risk of ICU-acquired bacteremia- a case-control study.

Background: Impaired intestinal barrier function can enable passage of enteric microorganisms into the bloodstream and lead to nosocomial bloodstream infections during critical illness. We aimed to determine the relative importance of gut translocation as a source for ICU-acquired enterococcal bacteremia of unknown origin.

Methods: We conducted a nested case-control study in two mixed medical-surgical tertiary ICUs in the Netherlands among patients enrolled between 2011 and 2018.

O-serotype distribution of Escherichia coli bloodstream infection isolates in critically ill patients in The Netherlands.

Objectives: Invasive infections by extra-intestinal pathogenic Escherichia coli (ExPEC) strains are increasing. We determined O-serogroups of E. coli isolates from ICU patients having bloodstream infections (BSI) and the potential coverage of a 10-valent O-polysaccharide conjugate vaccine currently in development for the prevention of invasive ExPEC disease.

The Diagnostic Yield of Routine Admission Blood Cultures in Critically Ill Patients.

Objectives: Although the Surviving Sepsis Campaign bundle recommends obtaining blood cultures within 1 hour of sepsis recognition, adherence is suboptimal in many settings. We, therefore, implemented routine blood culture collection for all nonelective ICU admissions (regardless of infection suspicion) and evaluated its diagnostic yield.

Design: A before-after analysis.

Robustness of sepsis-3 criteria in critically ill patients.

Background: Early recognition of sepsis is challenging, and diagnostic criteria have changed repeatedly. We assessed the robustness of sepsis-3 criteria in intensive care unit (ICU) patients.

Methods: We studied the apparent incidence and associated mortality of sepsis-3 among patients who were prospectively enrolled in the Molecular Diagnosis and Risk Stratification of Sepsis (MARS) cohort in the Netherlands, and explored the effects of minor variations in the precise definition and timing of diagnostic criteria for organ failure.

A pilot study of a novel molecular host response assay to diagnose infection in patients after high-risk gastro-intestinal surgery.

Purpose: SeptiCyte LAB measures the expression of four host-response RNAs in peripheral blood to distinguish sepsis from sterile inflammation. This study evaluates whether sequential monitoring of this assay has diagnostic utility in patients after esophageal surgery.

Materials And Methods: Patients who developed a complication within 30 days following esophageal surgery and a random sample of 100 patients having an uncomplicated course.
