Perinatal photoperiod associations with bipolar disorder and depression: A systematic literature review and cross-sectional analysis of the UK Biobank database Open
Season-of-birth associations with psychiatric disorders point to environmental (co-)aetiological factors such as natural photoperiod that, if clarified, may allow interventions toward prevention. We systematically reviewed the literature c…

COVID-19: Heterogeneous Excess Mortality and “Burden of Disease” in Germany and Italy and Their States and Regions, January–June 2020 Open
Total mortality and “burden of disease” in Germany and Italy and their states and regions were explored during the first COVID-19 wave by using publicly available data for 16 German states and 20 Italian regions from January 2016 to June 2…

Perinatal photoperiod and childhood cancer: pooled results from 182,856 individuals in the international childhood cancer cohort consortium (I4C) Open
Experimental evidence suggests that perinatal light imprinting of circadian clocks and systems may affect downstream physiology and cancer risk in later life. For humans, the predominant circadian stimulus is the daily light-dark cycle. He…

Premature Deaths, Statistical Lives, and Years of Life Lost: Identification, Quantification, and Valuation of Mortality Risks Open
Mortality effects of exposure to air pollution and other environmental hazards are often described by the estimated number of “premature” or “attributable” deaths and the economic value of a reduction in exposure as the product of an estim…

IARC 2019: “Night shift work” is probably carcinogenic: What about disturbed chronobiology in all walks of life? Open
In June of 2019, a working group convened by the International Agency for Research on Cancer [IARC] concluded that “night shift work” is probably carcinogenic to humans (a Group 2A carcinogen). This was based on sufficient evidence of canc…

The Risk of Developing Coal Workers' Pneumoconiosis in a German Inception Cohort of Coal Miners of Ruhr Area - Results after 30 Years of Follow-up Open
Comprehensive dust control and health protection measures have been implemented to prevent coal workers' pneumoconiosis (CWP) in German collieries since several decades. The present study evaluates the risk of developing CWP related to exp…

249 Effectiveness of a dose-based concept for dust control – a longitudinal study of coal miners’ in the ruhr area Open
Introduction A dose-based concept for dust control has been implemented in German coal mining since 1991. This concept foresees that miners with exposure to fibrogenic dusts cannot exceed a cumulative exposure of 440 total dust exposure va…
