Unionisation and injury risk in construction: a replication study.

Objective: To replicate, in a more recent time period, a previous cross-sectional study to estimate the association between unionisation and the risk of workers' compensation injury claims.

Methods: The sampling frame was workers' compensation company account records in the industrial, commercial and institutional construction sector in the province of Ontario, Canada, 2012-2018. Company unionisation status was determined through linkage with records of unionised contractors.

Protecting Construction Worker Health and Safety in Ontario, Canada: Identifying a Union Safety Effect.

Objectives: Do Ontario unionized construction firms have lower workers' compensation claims rates compared with nonunion firms?

Methods: Building trade and construction trade association lists of union contractors were linked to Workplace Safety and Insurance Board claims data for 2006 to 2012. Data were pooled for 2006 to 2012, and negative binomial regressions conducted with adjustment to estimate a union safety effect.

Results: The sample included 5797 unionized and 38,626 nonunion construction firms.

Nuclear factor kappaB downregulates the transient outward potassium current I(to,f) through control of KChIP2 expression.

Rationale: The fast transient outward K(+) current (I(to,f)) plays a critical role in early repolarization of the heart. I(to,f) is consistently downregulated in cardiac disease. Despite its importance, the regulation of I(to,f) in disease remains poorly understood.
