Prenatal exposure to alcohol causes a wide range of deficits known as Fetal Alcohol Spectrum Disorders (FASDs). Many factors determine vulnerability to developmental alcohol exposure including timing and pattern of exposure, nutrition, and genetics. Here, we characterized how a prevalent single nucleotide polymorphism in the human brain-derived neurotrophic factor (BDNF) gene (val66met) modulates FASDs severity. This polymorphism disrupts BDNF's intracellular trafficking and activity dependent secretion, and has been linked to increased incidence of neuropsychiatric disorders such as depression and anxiety...

With the global rising prevalence of gestational diabetes (GDM), an adaptable, economical approach to nutrition therapy that effectively controls maternal glycemia while promoting normal fetal growth will have far-reaching implications. The conventional focus has been to rigidly limit all types of carbohydrate. While controlling glucose, this approach fosters maternal anxiety and is a primary barrier to adherence. Many mothers substitute fat for carbohydrate, which may unintentionally enhance lipolysis, promote elevated free fatty acids (FFA), and worsen maternal insulin resistance (IR)...

AIMS: To investigate the role played by amniotic fluid in late fetal nutrition by analysis of infants born with digestive tract atresia. METHODS: Birth weight (BW), gestational age and gender of infants born with oesophageal (OA), duodenal (DA), jejunal (JA) and ileal atresia (IA) were recorded and BW Z-scores compared. Infants with incomplete obstruction (stenosis), chromosomal or syndromic conditions and multiple congenital malformations were excluded. Term infants admitted with suspected postnatal intestinal obstruction in whom no congenital malformation was found were used as a control group...

Maternal nutrition impacts fetal development, and may play a role in determining resilience to stress and vulnerability to stress-precipitated psychiatric disorders, such as anxiety and depression. In this study, we examined the effect of a reduction in maternal dietary protein during pregnancy on the brain neurochemistry and behavior of offspring. We focused specifically on the serotonin system, the 5-HT1A receptor and the responsivity of offspring as adults to stress. Dams were fed either a low protein diet (10% protein by weight) or isocaloric control diet (20% protein by weight)...

Precision medicine refers to treatment or prevention strategies in a group of individuals identified by their phenotype or genotype. Dietary components or patterns may play an important role in precision medicine. There is emerging evidence to support a role for n-3 (ω-3) fatty acids in lowering blood pressure and reducing the extent of subclinical atherosclerosis in people born with impaired fetal growth, a group at increased risk of coronary artery disease partly due to an increased risk of hypertensive disorders...

INTRODUCTION: Iodine is essential for normal brain development. Moderate and severe fetal iodine deficiency results in substantial to serious developmental delay in children. Mild iodine deficiency in pregnancy is associated with neurodevelopmental deficits in the offspring, but evidence from randomised trials is lacking. The aim of the Swedish Iodine in Pregnancy and Development in Children study is to determine the effect of daily supplementation with 150 µg iodine during pregnancy on the offspring's neuropsychological development up to 14 years of age...

In the United States, the American Thyroid Association recommends that women take a dietary supplement containing 150 µg of iodine 3 months prior to conception and while pregnant and lactating to support fetal growth and neurological development. We used data from the National Health and Nutrition Examination Survey 2011–2014 to describe the use of dietary supplements with and without iodine in the past 30 days among 2155 non-pregnant, non-lactating (NPNL) women; 122 pregnant women; and 61 lactating women...

Well-controlled intrauterine development is an essential condition for many aspects of normal adult physiology and health. This process is disrupted by poor maternal nutrition status during pregnancy. Indeed, physiological adaptations occur in the fetus to ensure nutrient supply to the most vital organs at the expense of the others, leading to irreversible consequences in tissue formation and differentiation. Evidence indicates that maternal undernutrition in early life promotes changes in key hormones, such as glucocorticoids, growth hormones, insulin-like growth factors, estrogens and androgens, during fetal development...

Fetal gastroschisis is a paraumbilical abdominal wall defect with herniation of abdominal organs. The underlying cause of the disease remains unknown; however, studies suggest that nutritional factors may play a role in its development. This prospective case-control study explored the association of serum fatty acid levels of pregnant women and occurrence of gastroschisis. Gastroschisis group comprised 57 pregnant women with fetuses with gastroschisis, and the control group comprised 114 pregnant women with normal fetuses...

BACKGROUND: Currently 20-35% of pregnant women are obese, posing a major health risk for mother and fetus. It is postulated that an abnormal maternal-fetal nutritional environment leads to adverse metabolic programming, resulting in altered substrate metabolism in the offspring and predisposing to risks of obesity and diabetes later in life. Data indicate that oocytes from overweight animals have abnormal mitochondria. We hypothesized that maternal obesity is associated with altered mitochondrial function in healthy neonatal offspring...

This review focuses on current understanding of prenatal, prepubertal and post-pubertal development of the male reproductive system of cattle. The critical developmental events occur during the first 3 to 4 months of gestation and the first ~6 to 9 months after birth. The Wilms Tumor-1 and SRY proteins play critical roles in early development and differentiation of the fetal testis, which in turn drives gestational development of the entire male reproductive system. The hypothalamic-pituitary-gonadal axis matures earlier in the bovine fetus than other domestic species with descent of the testes into the scrotum occurring around the 4th month of gestation...

Bovine mastitis is an infectious disease of the mammary gland which has been generally treated by antibiotic delivery. While the increasing drug-resistant bacteria and the high consumption of the antibiotic had become a noticeable concern. In a previous study, a mammary special vector expressing human β-defensin 3 (hBD3) was transfected into bovine fetal fibroblasts to produce mastitis-resistant bovine. This investigation focused on potential unintended effects of transgenic milk containing hBD3 produced by these mastitis-resistant bovine on the reproductive system of C57BL/6J mice...

The fetal origins of health and disease framework has identified extremes in fetal growth and birth weight as factors associated with the lifelong generation of chronic diseases such as obesity, diabetes, cardiovascular disease, and hypertension. Maternal nutrition plays a critical role in fetal and placental development, in part by providing the methyl groups required to establish the fetus's genome structure and function, notably through DNA methylation. The goal of this narrative review is to describe the role of maternal dietary methyl donor (methionine, folate, and choline) and cofactor (zinc and vitamins B2, B6, and B12) intake in one-carbon metabolism and DNA methylation in the fetus and placenta, as well as their impacts on fetal growth and lifelong health outcomes, with specific examples in animals and humans...

In the 1980s, mouse nuclear transplantation experiments revealed that both male and female parental genomes are required for successful development to term ( McGrath and Solter, 1983; Surani and Barton, 1983). This non-equivalence of parental genomes is because imprinted genes are predominantly expressed from only one parental chromosome. Uniparental inheritance of these genomic regions causes paediatric growth disorders such as Beckwith-Wiedemann and Silver-Russell syndromes (reviewed in Peters, 2014). More than 100 imprinted genes have now been discovered and the functions of many of these genes have been assessed in murine models...
