Background: Antimicrobial use data from inpatients in northern Canada suitable to inform stewardship programs are limited.

Objective: As a special project of the Canadian Nosocomial Infection Surveillance Program, to describe antimicrobial use for inpatients in northern Canadian acute care hospitals.

Methods: Participating acute care hospitals serving adult or mixed adult and pediatric populations in northern Canada submitted annual data on the use of all systemic antimicrobials from 2019 to 2021.

Objectives: SARS-CoV-2 viral load could be an important parameter for transmission potential. Here, we use RT-qPCR cycle threshold (Ct) values as a proxy for viral load. We assess the effect of COVID-19 vaccination and prior infection status on Ct value, while accounting for the virus variant.

Article Synopsis
  • The study investigates the immune mechanisms behind chronic lung allograft dysfunction (CLAD), which hampers long-term survival after lung transplants, using advanced tissue imaging techniques.
  • Researchers analyzed lung tissue from 23 transplant recipients, identifying differences in immune cell populations associated with CLAD versus non-CLAD conditions.
  • Key findings show that specific immune cells, like cytotoxic T cells and γδ T cells, expand in CLAD, highlighting unique characteristics in different CLAD phenotypes and offering new insights into how fibrosis progresses in these conditions.*

Background: Dengue is the most prevalent mosquito-borne viral disease and a major public health problem worldwide. Most primary infections with the four dengue virus serotypes (DENV1-4) are inapparent; nonetheless, whether the distribution of symptomatic versus inapparent infections by serotype varies remains unknown. Here, we present (1) the evaluation of a DENV1-4 envelope domain III multiplex microsphere-based assay (EDIII-MMBA) to serotype inapparent primary infections and (2) its application leveraging 17 years of prospective sample collection from the Nicaraguan Pediatric Dengue Cohort Study (PDCS).
