Obesity Is Associated With Increased Mortality in Patients Undergoing Venoarterial Extracorporeal Membrane Oxygenation.

Objectives: To determine the relationship between all-cause hospital mortality and morbidity in patients treated with venoarterial extracorporeal membrane oxygenation (ECMO) and to assess whether this relationship is mediated via body mass index (BMI).

Design: Using the Extracorporeal Life Support Organization (ELSO) registry, venoarterial ECMO runs from 2015 to 2021 were retrospectively analyzed. Patient demographics, ECMO indications, and complications for survivors and decedents were univariately compared.

Graduated responsibility and competency-based education in pathology residency programs: a five-year semi-longitudinal landscape assessment on autonomy and supervision.

Pathology residency training has been criticized for having too little opportunities for resident autonomy. As graduate medical education moves to competency-based models measuring competency and giving autonomy for specific tasks will be important. To determine how much autonomy residents are currently granted we surveyed pathology residency directors with regard to a list of usual pathology tasks and compared responses with those of a similar survey from 2018.

Risk factors for positive follow-up blood cultures in critically ill adults with Gram-negative bacteraemia.

Objectives: To evaluate the utility of follow-up blood cultures (FUBCs) for Gram-negative bloodstream infection (BSI) in ICU patients and identify risk factors for repeat positive cultures.

Methods: This was a single-centre, retrospective cohort study of critically ill adults with Gram-negative BSI between 1 January 2015 and 1 January 2020. Critically ill patients with one or more blood cultures positive for a Gram-negative organism were included.
