Impact of interventions on mpox transmission during the 2022 outbreak in Canada: a mathematical modeling study of three different cities.

Objectives: The global mpox (clade II) outbreak of 2022 primarily affected gay, bisexual, and other men who have sex with men (GBM) and was met with swift community and public health responses. We aimed to estimate the relative impact of changes in sexual behaviours, contact tracing/isolation, and first-dose vaccination on transmission in Canadian cities.

Methods: We estimated changes in sexual behaviours during the outbreak using 2022 data from the Engage Cohort Study which recruited self-identified GBM in Montréal, Toronto, and Vancouver (n=1,445).

Polymicrobial infection in cystic fibrosis and future perspectives for improving Mycobacterium abscessus drug discovery.

Polymicrobial communities inhabit the cystic fibrosis (CF) airway, whereby microbial interactions can occur. One prominent CF pathogen is Mycobacterium abscessus, whose treatment is largely unsuccessful. This creates a need to discover novel antimicrobial agents to treat M.

Cystic fibrosis sputum media induces an overall loss of antibiotic susceptibility in Mycobacterium abscessus.

Mycobacterium abscessus complex (MABSC) comprises a group of environmental microorganisms, which are a concerning cause of opportunistic respiratory infections in patients with cystic fibrosis or bronchiectasis. Only 45.6% of MABSC treatments are successful, and therefore this is a need to discover new antimicrobials that can treat these pathogens.

Extracellular acyl-CoA-binding protein as an independent biomarker of COVID-19 disease severity.

Background: Factors leading to severe COVID-19 remain partially known. New biomarkers predicting COVID-19 severity that are also causally involved in disease pathogenesis could improve patient management and contribute to the development of innovative therapies. Autophagy, a cytosolic structure degradation pathway is involved in the maintenance of cellular homeostasis, degradation of intracellular pathogens and generation of energy for immune responses.
