The changing epidemiology of infection and the NAP1/027 strain in two Québec hospitals: a 17-year time-series study.

Objective: To describe the epidemiology of healthcare-associated infection (HA-CDI) in two Québec hospitals in Canada following the 2003 epidemic and to evaluate the impact of antibiotic stewardship on the incidence of HA-CDI and the NAP1/027 strain.

Design: Time-series analysis.

Setting: Two Canadian tertiary care hospitals based in Montréal, Québec.

Comparison of rectal swabs and fecal samples for the detection of infections with a new in-house PCR assay.

Unlabelled: The detection of infections (CDI) relies on testing the stool of patients by toxin antigen detection or PCR methods. Although PCR and antigenic methods have significantly reduced the time to results, delays in stool collection can significantly add to the turnaround time. The use of rectal swabs to detect could considerably reduce the time to diagnosis of CDI.

A nested cohort 5-year Canadian surveillance of Gram-negative antimicrobial resistance for optimized antimicrobial therapy.

We analyzed 5 years (2016-2020) of nested Canadian data from the Study for Monitoring Antimicrobial Resistance Trends (SMART) to identify pathogen predominance and antimicrobial resistance (AMR) patterns of adult Gram-negative infections in Canadian health care and to complement other public surveillance programs and studies in Canada. A total of 6853 isolates were analyzed from medical (44%), surgical (18%), intensive care (22%) and emergency units (15%) and from respiratory tract (36%), intra-abdominal (25%), urinary tract (24%) and bloodstream (15%) infections. Overall, E.

Preventing Potential Patient Harm Through Clinical Content Interventions During Oncology Clinical Trial Implementation.

Objectives: Clinical trial documents are complex and may have inconsistencies, leading to potential site implementation errors and may compromise participant safety. This study characterizes the frequency and type of administrative and potential patient safety interventions (PPSIs) made during the review of oncology trial documents for clinical trial implementation by centralized clinical content specialists.

Methods: A dedicated group of centralized clinical content specialists reviewed trial documents, including the protocol, laboratory manual, and pharmacy/cellular therapy manual, and collected intervention data over a 1-year period.

Association Between Time-of-Day of Immune Checkpoint Blockade Administration and Outcomes in Metastatic Renal Cell Carcinoma.

Background: Preclinical evidence demonstrating circadian rhythmicity within the immune system provides a rationale for hypothesis that immune checkpoint inhibitor (ICI) infusion time-of-day may serve as an actionable mechanism to improve outcomes. Herein, we explore the association between ICI time of infusion (TOI) and outcomes in metastatic renal cell carcinoma (mRCC).

Methods: Data from patients with mRCC who received nivolumab or nivolumab/ipilimumab, in first- or second-line were retrospectively collected.
