Chemical and Physical Exposures in the Emerging US Green-Collar Workforce.

Objective: "Green collar" workers serve in occupations that directly improve environmental quality and sustainability. This study estimates and compares the prevalence of select physical and chemical exposures among green versus non-green U.S.

National estimates and correlates of secondhand smoke exposure in US cancer survivors.

Purpose: Cancer survivors comprise a vulnerable population for exposure to secondhand smoke (SHS). This study examined and compared the prevalence, time trends, and predictors of SHS exposure between nonsmoking adult cancer survivors and nonsmoking adults without cancer history (control group).

Methods: Data were obtained from the 2001-2012 National Health and Nutrition Examination Survey (survivors: n = 2168; controls: n = 19,436).

High bone turnover is an independent predictor of mortality in the frail elderly.

Unlabelled: Osteoporotic fractures are associated with accelerated bone turnover and excess mortality. In a prospective study of 1112 frail subjects (79% female; mean age, 86 years), high bone turnover was an independent predictor of all-cause mortality. This association seemed to be mainly manifested in deaths from cardiovascular causes.
