Bleeding disorders among young women: a population-based prevalence study.
Bleeding problems are prevalent in the general population but may indicate a general bleeding disorder. Our aim was to describe the prevalence of perceived bleeding symptoms, including menorrhagia, in young healthy females. ⋯ Bleeding symptoms were relatively prevalent in this population and similar to other population-based studies.

Self-reported nicotine exposure and plasma levels of cotinine in early and late pregnancy.
The accuracy of maternal self-reported smoking information, especially exposure to environmental tobacco smoke, has been questioned. This study aimed to validate self-reported smoking, smoking cessation, and environmental tobacco smoke exposure in early and late pregnancy, using the biomarker cotinine as the gold standard. ⋯ The results of this study indicate that self-reported smoking information among pregnant women can be trusted. However, among women reporting smoking cessation during pregnancy, the misclassification rate increased with recency of quitting. Environmental tobacco smoke exposure was common among non-smokers, and the low validity of self-reported environmental tobacco smoke exposure suggests that future studies on environmental tobacco smoke exposure and risks of pregnancy outcomes may have to rely on biomarker assessments.

Predictions for the decision-to-delivery interval for emergency cesarean sections in Norway.
To explain the variation in decision-to-delivery intervals in emergency cesarean sections in Norway. ⋯ The variance in the decision-to-delivery interval was mainly explained by the different nature of the cesarean sections. The most important predictors, which all acted to reduce decision-to-delivery interval, were the three indications abruptio placentae, cord prolapse, and fetal stress. Sections performed during night-time had significantly reduced decision-to-delivery interval. The size of the maternal units as measured by number of deliveries per year was not a significant predictor.
