Factors associated with bicycle helmet use and proper fit: a cross-sectional survey of Montreal cyclists during the COVID-19 pandemic.

Objectives: With increased bicycle use during the COVID-19 pandemic and growing availability of bicycle-sharing programs in Montreal, we hypothesize helmet use has decreased. The aim of this study was to evaluate helmet use and proper fit among Montreal cyclists during the pandemic relative to historical data.

Methods: Nine observers collected data on bike type, gender, helmet use, and ethnicity using the iHelmet© app at 18 locations across the island of Montreal from June to September 2021.

"Optimal surfactant delivery protocol using the bovine lipid extract surfactant: a quality improvement study".

Importance: Episodes of severe airway obstruction (SAO) are reported during surfactant administration.

Objective: To evaluate adherence to and impact of a surfactant protocol on adverse events.

Methods: An evidence-based protocol for surfactant administration was developed (2011), implemented (2012) and re-implemented (2014), including three major steps: lung recruitment, manual bagging, and bolus instillation.
