Randomized Controlled TrialReduced nicotine content cigarettes and nicotine patch.
Reduced nicotine content (RNC) cigarettes have led to smoking fewer cigarettes, withdrawal relief, and facilitation of cessation. The aim of this study is to examine the effects RNC cigarettes with and without nicotine patch and patch alone on smoking behavior, toxicant exposure, withdrawal discomfort, and as an exploratory analysis, on long-term abstinence. ⋯ These findings may have implications for smoking cessation treatment or a policy measure to reduce nicotine content in cigarettes.

Night shift work and levels of 6-sulfatoxymelatonin and cortisol in men.
Night shift work is associated with cancer among men, but the biologic mechanism is unclear. We investigated whether male night shift workers showed changes in levels of melatonin and cortisol, potential biomarkers of cancer risk. ⋯ Shift work could be an important risk factor for many types of cancer.
