Circadian variation of melatonin, light exposure, and diurnal preference in day and night shift workers of both sexes.
Light-at-night has been shown in experimental studies to disrupt melatonin production but this has only partly been confirmed in studies of night shift workers. In this cross-sectional study, we examined the circadian variation of melatonin in relation to shift status, individual levels of light-at-night exposure, and diurnal preference, an attribute reflecting personal preference for activity in the morning or evening. ⋯ Night shift work affects levels and timing of melatonin production and both parameters may relate to future cancer risk.

The global burden of disease for skin, lung, and bladder cancer caused by arsenic in food.
Arsenic is a ubiquitous, naturally occurring metalloid that poses a significant human cancer risk. While water consumption provides the majority of human exposure, millions of individuals worldwide are significantly exposed to arsenic through naturally occurring levels of arsenic in grains, vegetables, meats and fish, as well as through food processed with water containing arsenic. Thus, we estimated the global burdens of disease for bladder, lung, and skin cancers attributable to inorganic arsenic in food. ⋯ Estimating the global cancer burden caused by arsenic exposure in food will support policies that reduce exposure to disease-promoting environmental hazards.

Risk of hospitalization for survivors of childhood and adolescent cancer.
Childhood cancer survivors may be at increased risk of hospitalization because of cancer-related late effects. ⋯ Research to identify strategies to prevent and manage survivors' health problems in outpatient settings is needed.
