The impact of regulatory workplace safety inspections on workers' compensation claim rates.

Background: Studies on the impact of workplace safety inspections on work injuries have found mixed effectiveness. Most studies are from the United States, examining Occupational Health and Safety Administration (OSHA) regulatory inspections in manufacturing firms with more than 10 employees. This study examines whether regulatory inspections in Alberta, Canada, result in reductions in workers' compensation claims rates for inspected firms relative to comparable non-inspected firms.

[Construction, Identification, and Expression of -Based Recombinant Vaccine for ].

Objective: To construct (LL)-based recombinant LL-Eg95 (rLL-Eg95) vaccine for (Eg) and to examine its expression efficiency.

Methods: 95 gene was obtained by PCR from the template of pCD-95. Then, pMG36e was inserted in the 95 gene after double cleaving with restriction endonucleases Ⅰ and dⅢ to construct recombinant plasmid pMG36e-95, which was transformed into BL2 (DE3) competent cells.

Evaluating effectiveness of an integrated return-to-work and vocational rehabilitation program on work disability duration in the construction sector.

Objective: The aim of this study was to investigate whether an integrated return-to-work (RTW) and vocational rehabilitation (VR) program - the Work Reintegration (WR) program - was associated with reduced work disability duration in the construction sector in Ontario, Canada.

Methods: Workers' compensation data from the Ontario Workplace Safety and Insurance Board were extracted for lost-time construction worker claims following work-related injuries between 2009 and 2015. Claims receiving referrals to RTW and VR specialists (treatments) were matched with claims receiving no referrals (controls) during the periods before and after the WR program introduction.
