Several studies have examined associations between particulate matter with aerodynamic diameter of 2.5 µm or less (PM2.5) and preterm birth, but it is uncertain whether results were affected by individual predispositions (e.g., genetic factors, social conditions) that might vary considerably between women. We tested the hypothesis that a woman is ...

Maternal exposure to polycyclic aromatic hydrocarbons (PAH) during pregnancy has been associated with reduced fetal growth. However, the role of diet, the main source of PAH exposure among non-smokers, remains uncertain. To assess associations between maternal exposure to dietary intake of the genotoxic PAH benzo(a)pyrene [B(a)P] during pregnancy and birth ...

Case reports suggest that long-term, high-dose fluconazole treatment for severe fungal infections during pregnancy causes a pattern of birth defects. It is unclear whether commonly used lower doses increase the risk of specific birth defects. In a registry-based cohort of liveborn infants in Denmark, we evaluated first-trimester oral fluconazole exposure ...

One explanation for the large increase in the prevalence of atopic disease during the last 50 years in developed countries is the 'hygiene hypothesis'. This proposes that a reduced exposure to pathogenic microorganisms at a key period(s) during development result in the maintenance or acquisition of an atopic phenotype. Alternatively, ...

An adverse early life environment is associated with long-term disease consequences. Adversity early in life is hypothesized to elicit developmental adaptations that serve to improve fetal and postnatal survival and prepare the organism for a particular range of postnatal environments. These processes, while adaptive in their nature, may later prove ...

Polychlorinated biphenyls (PCBs) remain ubiquitous environmental contaminants. Developmental exposures are suspected to impact reproduction. Analysis of mixtures of PCBs may be problematic as components have a complex correlation structure, and along with limited sample sizes, standard regression strategies are problematic. We compared the results of a novel, empirical method to ...

The effect of fetal radiation during endoscopic retrograde cholangiopancreatography (ERCP) on pregnant women is a very interesting topic. Smith et al recently estimated the fetal radiation exposure in pregnant women undergoing ERCPs using thermoluminescent dosimeters (TLDs). The authors concluded that TLDs are unnecessary during ERCP with modified techniques. We believe ...

Maternal urinary biomarkers are often used to assess fetal exposure to phenols and their precursors. Their effectiveness as a measure of exposure in epidemiological studies depends on their variability during pregnancy and their ability to accurately predict fetal exposure. We assessed the relationship between urinary and amniotic fluid concentrations of ...

Ethanol consumption during pregnancy is a widespread problem which is increasing in the generation of young women. Gestational alcohol consumption causes fetal exposure to this teratogen and is associated with the onset of fetal alcohol spectrum disorders (FASD) including fetal alcohol syndrome (FAS). FASD and FAS can lead to several ...
