The recent detection of benzonitrile (CHCN) in the interstellar medium is one of the most fascinating discoveries in astrochemistry and molecular astrophysics. However, the mechanism of its formation in interstellar ices remains unclear. Here, we report the first evidence for the direct synthesis of benzonitrile through the radiation-induced transformations of an isolated CH···HCN complex in inert rigid media at cryogenic temperature (4.

Objective: The COVID-19 pandemic highlighted and exacerbated health inequities worldwide. While several studies have examined the impact of individual social factors on COVID infection, our objective was to examine how interactions of social factors were associated with the risk of testing positive for SARS-CoV-2 during the first two years of the pandemic.
Study Design And Setting: We conducted an observational cohort study using linked health administrative data for Ontarians tested for SARS-CoV-2 between January 1st, 2020, and December 31st, 2021.

Introduction: As the drug toxicity crisis continues to evolve globally, harms related to non-opioid substances, including stimulants, have risen in parallel. Our study aims were to describe trends in accidental stimulant toxicity deaths and to characterize demographic characteristics of decedents and the circumstances surrounding death.
Methods: We conducted a population-based repeated cross-sectional study, of all accidental stimulant toxicity deaths between January 1, 2018, and December 31, 2021, in Ontario, Canada.

Background And Hypothesis: While maternal schizophrenia is linked to chronic childhood medical conditions, little is known about the risk of acute asthma exacerbations among children whose mothers have schizophrenia. This population-based study used health data for all of Ontario, Canada to evaluate whether having a mother with schizophrenia was associated with increased risk of asthma exacerbations.
Study Design: The study cohort included 385,989 children diagnosed with asthma from age 2 years onward, followed from the time of their asthma diagnosis up to a maximum of age 19 years.

Background: Antimicrobial-resistant (AMR) pathogens represent an ongoing global health burden. Colonization is often a prerequisite for infection, but the risk of infection after AMR colonization is not well understood. Using population-level health administrative data, we sought to investigate the risk of infection with the same AMR organism after detection of colonization.
