OBJECTIVE Periconceptional use of folic acid can prevent birth defects, including at least 50% of neural tube defects. This study used an ongoing surveillance system to explore the association between pregnancy intendedness and women taking periconceptional folic acid. METHODS Oregon Pregnancy Risk Assessment Monitoring System (PRAMS) surveys a stratified random sample of women after a live b...

Background. Numerous rare genetic conditions are known to influence fecundability in both males and females. It is less clear to what extent more subtle genetic differences influence fecundability on a population level. Methods. In 1994 a population-based survey was conducted among Danish twins born 1953-1982. Fecundability was assessed as the waiting time to pregnancy at the first attempt to a...

The outcome of pregnancy was studied among personnel employed in laboratory work at the University of Gothenburg between 1968 and 1979. A questionnaire was distributed to 782 women; the response rate was 95%. When the 1160 pregnancies were divided into those with and without exposure to organic solvents during laboratory work, a slightly increased, but not significant, difference in the miscarr...

Previous research has suggested that exposure to elevated levels of drinking water disinfection by-products (DBPs) may cause pregnancy loss. In 2000-2004, the authors conducted a study in three US locations of varying DBP levels and evaluated 2,409 women in early pregnancy to assess their tap water DBP concentrations, water use, other risk factors, and pregnancy outcome. Tap water concentration...

Maternal smoking during pregnancy is associated with attention deficit hyperactivity disorder (ADHD) in offspring. It is assumed by many that this association is causal. Others suggest that observed associations are due to unmeasured genetic factors or other confounding factors. The authors compared risks of maternal smoking during pregnancy with those of paternal smoking during pregnancy. With...

PURPOSE OF REVIEW The management of uterine fibroids in patients requiring treatment who desire future fertility remains controversial. Myomectomy has been the most common operative procedure to improve pregnancy rates and outcomes. Uterine fibroid embolization is an increasingly popular, minimally invasive treatment for fibroids. This review aims to provide critical analysis of available data ...

To understand the full extent of the impact of a trial, it is important to consider the long-term consequences of outcomes beyond the trial follow-up period, especially for early year's interventions. A systematic review of the literature associated with the long-term consequences of four key outcomes from the Building Blocks trial, specifically, low birth weight, smoking during pregnancy, inte...

Background: Controlled ovarian stimulation (COS) has been shown to advance endometrial maturation and affect adversely implantation in assisted reproduction technology (ART) cycles. It has been reported that there is a better embryo-endometrium synchrony in frozenthawed embryo transfer (FET) cycles than fresh embryo transfer (ET) cycles. The Background of this study was to compare ongoing pregn...

this prospective longitudinal study deals with the associations between digital disorders and reproduction indices in dairy cattle on a farm in the vicinity of tehran. it was carried out on 225 postparturient holstein heifers. the evaluation of lameness due to digital disorders on postpartum period of heifers were done and after diagnosis of lameness (based on a 5 points lameness scoring system...

objective: comparing sublingual and vaginal misoprostol in second trimester pregnancy termination. materials and methods: in this study 268 women at 12-24 weeks of gestation candidate for pregnancy termination were enrolled. women were randomly divided in two groups. the first group received 400 µg sublingual misoprostol and vaginal placebo and the second group received 400 µg vaginal misoprost...
