Introduction: Understanding the impact of non-pharmaceutical COVID-19 interventions (NPIs) on road safety has become increasingly important to uncover the unintended consequences of the pandemic. This study explores how NPIs influenced alcohol-related and speed-related traffic collisions, including fatalities and serious injuries, in five cities of the province of Québec, Canada: Montréal, Québec, Laval, Longueuil and Sherbrooke.

Methods: We performed Poisson interrupted time-series analyses using daily traffic fatality and injury data from 2015 to 2022, to assess the change in rate expressed per 10 000 population.

Article Synopsis
  • The PERFORM-TAVR trial aims to explore the combined effects of exercise and protein supplementation on older adults with frailty undergoing transcatheter aortic valve replacement (TAVR), which currently shows high procedural success but still leaves many patients with poor health outcomes.
  • This multicentre trial will enroll 200 frail adults aged 70 and older, randomly assigning them to either standard lifestyle education (control) or a regimen involving protein-rich supplements and supervised exercises post-TAVR.
  • The main goal is to measure physical performance improvements at 3 months, along with secondary outcomes like health-related quality of life and safety assessments over a year, potentially reshaping approaches to treating frailty alongside heart valve diseases.

Forward collision warning systems (FCWSs) monitor the road ahead and warn drivers when the time to collision reaches a certain threshold. Using a driving simulator, this study compared the effects of FCWSs between novice drivers (unlicensed drivers) and experienced drivers (holding a driving license for at least four years) on near-collision events, as well as visual and driving behaviors. The experimental drives lasted about six hours spread over six consecutive weeks.

Lane Departure Warning Systems (LDWS) are automation that warn drivers in case of immediate lane departure. While LDWS are associated with increased road safety, little is known about the neural aspects of the cooperation between an LDWS and the driver behind the wheel. The present study addresses this issue by combining fMRI and driving simulation for experienced and novice drivers.

Article Synopsis
  • Driver distraction, especially mind wandering, causes crashes in young drivers, so a study tested brief online mindfulness training (MT) to help reduce this distraction.
  • The study involved 26 young drivers who either took the mindfulness training or another relaxation method, and their driving behaviors were measured in a simulator.
  • Results showed that those who did the mindfulness training were better at focusing and reported less mind wandering while driving, suggesting this method could help reduce crash risks in young drivers.

Introduction: In the past decade, a group of studies has begun to explore the association between cannabis recreational use policies and traffic crashes. After these policies are set in place, several factors may affect cannabis consumption, including the number of cannabis stores (NCS) per capita. This study examines the association between the enactment of Canada's Cannabis Act (CCA) (18 October 2018) and the NCS (allowed to function from 1 April 2019) with traffic injuries in Toronto.

Background: Brazil occupies the fifth position in the ranking of the highest mortality rates due to RTI in the world. With the objective of promoting traffic safety and consequently reducing deaths, Brazil created the Life in Traffic Project (LTP). The main goal of LTP is reducing 50% of RTI deaths, by promoting interventions to tackle risk factors, such as driving under the influence of alcohol and excessive and/or inappropriate speed.

Background: Although multidimensional frailty scales have been proven to predict mortality and morbidity in cardiac surgery, there is a need for rapid tools that could be easily administered at the point of care. Handgrip strength (HGS) is an attractive option that can be measured in acutely ill and bed-bound patients, although it has yet to be validated in a large cardiac surgery cohort.

Methods: This is a post hoc analysis of a multicentre prospective study in older patients undergoing coronary artery bypass grafting and/or valve surgery from 2011 to 2019.

Background: Few studies have measured frailty as a potential reason for foregoing transcatheter aortic valve replacement (TAVR) in older adults with severe aortic stenosis (AS). This study sought to determine the impact of frailty and other clinician-cited reasons on restricted mean survival time (RMST).

Methods: An analysis of the McGill Frailty Registry was conducted between 2014 and 2018 at the McGill University Health Center Structural Valve Clinic.

Article Synopsis
  • Young drivers often make the risky choice to drink and drive, and several things can affect this decision, like how much they drink and whether they get feedback about their alcohol level in the car.
  • A study with 160 young adults tested if lower alcohol levels, lack of feedback devices, and how they feel about their own intoxication affected their choice to drink-drive.
  • Results showed around 60% of participants chose to drink and drive, especially males who felt more capable of driving safely, but the study didn't find a big difference based on alcohol amount or feedback devices.

Article Synopsis
  • Researchers studied drivers who got caught drinking and driving (DWI) to understand why some get into trouble again.
  • They looked at how well a certain stress response in the body (called cortisol) might predict if someone will get into more trouble on the roads.
  • The study found that people with a weaker stress response had a higher chance of getting more traffic tickets, which suggests that they might be at greater risk for dangerous driving behavior.

Background: Heterogeneity in the driving while impaired (DWI) offender population and modest outcomes from remedial programs are fueling interest in clarifying clinically significant DWI subtypes to better assess recidivism risk and target interventions. Our previous research identified 2 putative behavior phenotypes of DWI offenders with distinct behavioral, personality, cognitive, and neurobiological profiles: (i) offenders primarily engaging in DWI (pDWI); and (ii) offenders engaging in DWI and other traffic violations (MIXED). Here, we evaluate these phenotypes' clinical significance for prediction of recidivism and intervention targeting.
