Nighttime-breathing treatments backed by strongest evidence among options to treat sleep apnea
AHRQ    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Among the treatments for obstructive sleep apnea, the effectiveness of a nighttime-breathing machine called a "CPAP" was backed by the strongest evidence, and a mouthpiece worn at night was also shown to be effective, according to a new report funded by HHS' Agency for Healthcare Research and Quality (AHRQ).

Exposure to pesticides and metal contaminants of fertilizer among tree planters
The Annals of Occupational Hygiene    Share    Share on FacebookTwitterShare on LinkedinE-mail article
In British Columbia, Canada, harvested forests are manually replanted by seasonal workers. The work is known to be physically demanding and ergonomically difficult, and recently, there have been concerns over chemical exposures due to pesticide residues on seedlings, fertilizers (often applied alongside seedlings), and potential metal contamination of these fertilizers. This study aimed to characterize metal and pesticide exposure among a sample of British Columbia tree planters. More

Meta-analyses of published epidemiological studies, 1979-2006, point to open causal questions in silica-silicosis-lung cancer research
PubMed    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Following up on a previous meta-analysis of lung cancer risk in individuals without silicosis, we provide more detailed results of silica associated lung cancer risk in both silicotics and non-silicotics. The objective was to examine in depth whether current data allows to answer the pressing question "does silica cause lung cancer in the absence of silicosis"? More

NIMH RAISE Project makes progress as teams refine research approaches
NIMH    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Researchers continue to make progress in the NIMH Recovery After an Initial Schizophrenia Episode (RAISE) Project, which seeks to intervene at the earliest stages of illness in order to prevent long term disability. Recent refinements to the two RAISE studies will ensure that RAISE continues efficiently, and generates results that will be relevant to consumers and health care policy makers.

The opinion of the Italian Society of Occupational Medicine and Industrial Hygiene (SIMLII) on silica-exposure and lung cancer risk
PubMed    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The Italian Society of Occupational Medicine and Industrial Hygiene (SIMLII) began a thorough overview of the silica-silicosis-lung cancer question starting in 2005. The body of information obtained from a number of epidemiological studies, meta-analyses and reviews following the decision of the IARC to classify Respirable Crystalline Silica (RCS) as a human carcinogen (Group 1) led to different conclusions, which can be summarized as follows: basically an increased risk of developing lung cancer is demonstrated and generally accepted for silicotics; the association of lung cancer and exposure to silica per se is controversial, with some studies in favour of an association and some leading to contrary conclusions. Due to methodological problems affecting most studies and the difficulty in identifying the mechanism of action, we agree that the silica-lung cancer association is still unclear. More

Medium-density fiberboard (MDF) is a wood composite material, composed primarily of softwood, bonded with a synthetic formaldehyde-based resin. It is increasingly used, as it has various advantages over natural woods. More

Study tracks US military members' malaria rates
OH&S    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Malaria rates among members of the U.S. military who were born in western Africa were 44 times higher during 2002-2010 than rates for members who were born in the United States, authors of a paper being published in the September issue of CDC's Emerging Infectious Diseases journal report. More

US Department of Transportation launches initiative to prevent employee fatigue and increase safety on America's railways
USDOT    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The U.S. Department of Transportation issued a final rule today limiting the number of consecutive hours passenger railroad workers can be on the job. The new Federal Railroad Administration (FRA) regulation will reduce risk and improve safety for the railroad industry, and for the first time, differentiate between freight and passenger service. Designed to reduce accidents related to fatigue, the final rule applies "fatigue science" to employee work schedules to determine maximum on-duty periods and minimum off-duty periods. The Department is engaging in a broad initiative to bring scientific data into work scheduling, and the FRA rule is the first rule in that effort to be completed. More
