Exposure to disinfection by-products (DBPs) has been demonstrated to impair male reproductive health in animals, but human evidence is limited and inconsistent. The researchers examined the association between exposure to drinking-water DBPs and semen quality in a Chinese population.

Smoking increases the risk of many diseases, and it is also linked to blood DNA methylation changes that may be important in disease etiology. The objective of the study was to identify novel CpG sites associated with cigarette smoking.

A growing number of studies link chronic exposure to inorganic arsenic (iAs) with risk of diabetes. Many of these studies assessed iAs exposure by measuring arsenic (As) species in urine. However, this approach has been criticized because of uncertainties associated with renal function and urine dilution in diabetic individuals. In this study the researchers measured concentrations of trivalent and pentavalent iAs, methyl-As (MAs), and dimethyl-As (DMAs) species in EUC from 374 residents of Chihuahua, Mexico, who were exposed to iAs in drinking water.

The objective of the study was to evaluate whether residential proximity to agricultural pesticides during pregnancy is associated with autism spectrum disorders (ASD) or developmental delay (DD) in the Childhood Autism Risks from Genetics and Environment (CHARGE) Study.

A body of literature has developed suggesting an elevated risk of lung cancer associated with particulate matter and traffic-related pollutants. The researchers examined the relation of lung cancer incidence with long-term residential exposures to ambient particulate matter and residential distance to roadway, as a proxy for traffic-related exposures.

The present analysis included 381 women enrolled in the Study of Women and Babies (SOWB) during 2010–2011, from eight South African villages in the Limpopo Province, South Africa. Indoor residual spraying (IRS) occurred in half of the villages. Questionnaires regarding various demographic and medical factors were administered and blood samples were obtained.

Over the past two decades Denmark has instituted reforms to antibiotic use for livestock that are showing solid progress in reducing the prevalence of resistant bacteria.

Recently, the dilemma of human–wildlife conflict has created great opportunity to solve some of the world’s most pressing problems for both people and ecosystems. The emerging “One Health” movemen explicitly recognizes the inextricable connections between human, animal, and ecosystem health and is leading not only to new scientific research but also to projects that help people rise out of poverty, improve their health, reduce conflicts with wildlife, and preserve ecosystems, such as Bwindi’s tropical montane forest.

The aim of this study was to investigate effects of long-term aircraft noise exposure on body mass index (BMI), waist circumference, and Type 2 diabetes. Furthermore, the researchers explored the modifying effects of sleep disturbance

Exposure to persistent organic pollutants (POPs) during fetal development can increase the risk of adverse health effects during childhood. Maternal characteristics and physiological changes during gestation such as gestational weight gain (GWG) may have an influence in the overall burden of POPs in neonates. However, the associations between GWG and POP concentrations are still not well established.
