Randomized Controlled Trial Multicenter StudyEfficacy of face masks and respirators in preventing upper respiratory tract bacterial colonization and co-infection in hospital healthcare workers.
We compared the efficacy of medical masks (MM) and N95 respirators (N95) in preventing bacterial colonization/infection in healthcare workers (HCWs). ⋯ N95 respirators were significantly protective against bacterial colonization, co-colonization and viral-bacterial co-infection. We showed that dual respiratory virus or bacterial-viral co-infections can be reduced by the use of N95 respirators. This study has occupational health and safety implications for health workers.

Randomized Controlled Trial Multicenter StudyThe impact of product information and trials on demand for smokeless tobacco and cigarettes: evidence from experimental auctions.
Epidemiological and toxicological evidence suggests lower risk of smokeless tobacco (ST) products compared to cigarettes. Less is known, however, about consumer perceptions and use of novel forms of ST, including snus and dissolvable tobacco. ⋯ These findings suggest that credible and effective communications about tobacco harm reduction should reinforce the negative effects of smoking.
