Purpose: To elucidate drug use before and during pregnancy in Japan. Methods: The Japan Environment and Children's Study (JECS) is an ongoing nationwide birth cohort study. We analyzed data from JECS involving cases where drugs were used for 12 months before pregnancy was diagnosed, between the time of diagnosis of pregnancy until week 12 of pregnancy, and after week 12 of pregnancy. Results: We analyzed data from 97,464 pregnant women. The percentages of pregnant women who had taken one or more drugs and supplements before diagnosis of pregnancy, between the time of diagnosis of pregnancy until week 12 of pregnancy, and after week 12 of pregnancy, were 78...

BACKGROUND: We examined the association of hypospadias risk with maternal smoking and consumption of alcohol and caffeine. METHODS: We analyzed data from mothers of 2437 moderate/severe cases and 5472 nonmalformed controls born from 1997 to 2011 who participated in the National Birth Defects Prevention Study (NBDPS). Exposures were assessed by maternal telephone interviews. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs) adjusted for mother's age, parity, race-ethnicity, education, vitamin/mineral supplement intake, obesity, and study center...

The Australasian Psoriasis Collaboration has reviewed the evidence for managing moderate to severe psoriasis in those who are pregnant or are breast-feeding, or planning a family. The severity of the psoriasis, associated comorbidities and specific anti-psoriasis treatment, along with other exposures, can have a deleterious effect on pregnancy outcomes. Psoriasis itself increases the risk of preterm and low birthweight babies, along with spontaneous and induced abortions, but no specific birth defects have been otherwise demonstrated...

Epidemiologic studies have linked gestational vitamin D deficiency to respiratory diseases, although mechanisms have not been defined. We hypothesized that antenatal vitamin D deficiency would impair airway development and alveolarization in a mouse model. We studied the effect of antenatal vitamin D deficiency by inducing it in pregnant mice and then compared lung development and function in their offspring to littermate controls. Postnatal vitamin D deficiency and sufficiency models from each group were also studied...

BACKGROUND: Valproic acid (VPA) is prescribed therapeutically for multiple conditions, including epilepsy. When taken during pregnancy, VPA is teratogenic, increasing the risk of several birth and developmental defects including neural tube defects (NTDs). The mechanism by which VPA causes NTDs remains controversial and how VPA interacts with folic acid (FA), a vitamin commonly recommended for the prevention of NTDs, remains uncertain. We sought to address both questions by applying untargeted metabolite profiling analysis to neural tube closure (NTC) stage mouse embryos...

Supplementation with folic acid (FA) was proven to prevent neural tube defects (NTDs) and was recommended worldwide before and during early pregnancy. However, much less is known regarding the role of FA after the 12th gestational week (GW). This study aimed to investigate the related effects of continued FA supplementation after the first trimester of pregnancy on fetal growth. The study subjects came from the Ma'anshan-Anhui Birth Cohort Study (MABC) that recruited 3474 pregnant women from the city of Ma'anshan in Anhui Province in China during the period of May 2013 to September 2014...

BACKGROUND: A nutrient-rich maternal diet before and during pregnancy is associated with improved fetal health, more appropriate birth weight, and increased rates of maternal and infant survival. Physicians need a better understanding of the role of diet in shaping fetal outcomes. Given this background, we reviewed and summarized articles on maternal nutrition found in MEDLINE since 1981, written in English, and limited to human subjects. FOR THE OFFSPRING: Maternal diets high in sugar and fat lead to an increased incidence of metabolic syndrome, diabetes, and cardiovascular disease later in life...

Today, direct oral anticoagulants (DOAC) are widely used alternatives to Vitamin-K antagonists (VKA). Women of reproductive age may become pregnant during anticoagulation and, while VKA carry an embryotoxic potential, the risk of DOAC embryopathy is unknown. As a result, some patients elect to terminate pregnancy for fear of DOAC embryotoxicity. To assess the risk of DOAC embryopathy, we reviewed cases of DOAC exposure in pregnancy collected from physicians, literature and pharmacovigilance systems of drug authorities and manufacturers...

BACKGROUND: This study was conducted to determine whether low folate and vitamin B12 levels, as well as high homocysteine levels in pregnant women are associated with neural tube defects (NTDs) in Tunisia. METHODS: A total of 75 NTDs pregnancies and 75 matched controls were included in the study. Their vitamin B12, folate, and red blood cell folate concentrations were measured using a radio-immunoassay kit and total homocysteine concentrations were determined using a fluorescent polarization immunoassay...

Neural tube defects (NTDs) are a group of congenital malformations with worldwide distribution and complex etiopathogenesis. Folic acid plays a pivotal role in their prevention. We aimed to identify the protective effect of folic acid intake against NTDs and its dependence on different socioeconomic and environmental factors in a cohort of mothers in Egypt. A cross-sectional study was carried over a period of 12 months on mothers who gave birth to babies with NTDs (group 1) and a control group with healthy offsprings (group 2)...

Beer is a natural beverage low calorie, low degree of alcohol, no fats or sugars and a significant amount of carbohydrates, vitamins, and proteins. Beneficial health qualities are based on the presence in the beer of antioxidant compounds (polyphenols), which reduce the presence of free radicals in the organism, and phytoestrogens, elements biosimilars to natural estrogens. In pregnant women, beer, obviously alcohol-free, presents elements in its composition that differ it from other fermented beverages as it is the folic acid, vitamin necessary to prevent defects of the neural tube in the fetus or regulate homocysteine...

UNLABELLED: PREGNANCY AND FOLIC ACID: Pregnancy is the most important period in life of every woman, partially for the number of physiological adaptations she is going through, partially for the expectance of new life. In addition, pregnancy is the "critical window" for development later in childhood, as a period of foetal programming during which nutrition plays one of crucial roles. Despite the general belief that nutrition through pregnancy is adequate and characterized by better nutritional habits, a number of studies do not corroborate this belief...

PURPOSE OF REVIEW: Provide a rationale for attempting prevention of congenital heart defects (CHDs). RECENT FINDINGS: Prevention of neural-tube defects can be achieved with preconceptional use of folic acid. Extrapolating results from animal studies to human pregnancy shows that folate deficiency as well as one-time exposure to environmental factors in the first 2 to 3 weeks of human gestation can result in severe CHD. Considering that approximately 50% of pregnancies are unplanned, this period of pregnancy can be considered high risk for cardiac, as well as neural, birth defects, as the woman usually is not aware of her pregnancy and may not yet be taking precautionary actions to protect the developing embryo...

BACKGROUND: In 2010 a Cochrane review confirmed that folic acid (FA) supplementation prevents the first- and second-time occurrence of neural tube defects (NTDs). At present some evidence from observational studies supports the hypothesis that FA supplementation can reduce the risk of all congenital malformations (CMs) or the risk of a specific and selected group of them, namely cardiac defects and oral clefts. Furthermore, the effects on the prevention of prematurity, foetal growth retardation and pre-eclampsia are unclear...
