Purpose: We hypothesised that the biological heterogeneity of sepsis may highlight sepsis subtypes with differences in response to intravenous vitamin C treatment in the Lessening Organ Dysfunction with VITamin C (LOVIT) trial. Our aims were to identify sepsis subtypes and to test whether sepsis subtypes have differences in treatment effect to vitamin C and describe putative biological effects of vitamin C treatment.

Methods: We measured biomarkers of inflammation, at baseline and at 7 days post-randomisation, in 457/863 (53.

Article Synopsis
  • The study investigates differences in thrombo-inflammatory responses and outcomes between non-COVID-19 community-acquired pneumonia (CAP) and COVID-19 CAP in hospitalized adults in Canada.
  • Non-COVID-19 CAP patients displayed lower 28-day mortality rates and fewer complications compared to those with COVID-19, indicating a more effective immune response developed over time against bacterial infections.
  • The findings suggest that the complexities of the immune response to COVID-19 resulted in higher mortality rates, highlighting the challenges posed by emerging viruses compared to known pathogens.

Background: Most Canadians receive their care in community hospitals, yet most clinical research is conducted in academic hospitals. This study aims to compare patients with community acquired pneumonia (CAP) treated in academic and community hospitals with respect to their demographics, clinical characteristics, treatments and outcomes.

Methods: This nested observational cohort substudy of the Community Acquired Pneumonia: Toward InnoVAtive Treatment (CAPTIVATE) trial included 1,329 hospitalized adults with CAP recruited between March 1st, 2018 and September 31st, 2023 from 15 Canadian hospitals.

Background: Bloodstream infections are associated with substantial morbidity and mortality. Early, appropriate antibiotic therapy is important, but the duration of treatment is uncertain.

Methods: In a multicenter, noninferiority trial, we randomly assigned hospitalized patients (including patients in the intensive care unit [ICU]) who had bloodstream infection to receive antibiotic treatment for 7 days or 14 days.
