Background: Fetal growth is dependent on placental nutrient supply, which is influenced by placental perfusion and transporter abundance. Previous research indicates that adequate choline nutrition during pregnancy improves placental vascular development, supporting the hypothesis that choline may affect placental nutrient transport.Objective: The present study sought to determine the impact of maternal choline supplementation (MCS) on placental nutrient transporter abundance and nutrient metabolism during late gestation...

AIM: We aimed to investigate maternal serum angiogenic marker profiles within 1 week prior to delivery in cases of gestational hypertension (GH), pre-eclampsia (PE), and/or fetal growth restriction (FGR) with different clinical conditions. METHODS: We enrolled 165 women with singleton pregnancy. The participants were classified based on three characteristics: (i) proteinuria (GH and PE); (ii) FGR (PE with FGR [PE + FGR], PE alone, and FGR alone); and (iii) onset (early onset PE [EO PE] and late-onset PE [LO PE])...

OBJECTIVE: We assessed whether umbilical cord blood placental growth factor (PlGF) levels at delivery are associated with fetal growth. METHODS: From a prospective population-based cohort study we included 3,461 live singleton births. Fetal growth was assessed by birth weight, fetal growth pattern, and fetal growth restriction (FGR; decrease in growth between the second trimester and birth of ≥40 percentiles). In all analyses the highest PlGF multiple of the median (MoM) quintile was used as the reference category...

BACKGROUND: Hypoglycaemia accounts for approximately one tenth of term admissions to neonatal units, can cause long-term neurodevelopmental impairment and is associated with significant burden to the affected infants, families and the health system. OBJECTIVE: To define the prevalence, length and cost of admissions for hypoglycaemia in infants born at greater than 35 weeks gestation and to identify antenatal and perinatal predictors of those outcomes. MATERIAL AND METHODS: This was a retrospective audit of infants admitted for hypoglycaemia between 1/1/2012 and 31/12/2015, in a level three neonatal intensive care unit at King's College Hospital NHS Foundation Trust, London...

Undifferentiated connective tissue diseases (UCTDs) are a heterogeneous group of disorders characterized by symptoms and signs suggestive of systemic autoimmune rheumatic disease (ARD), but which do not fulfill all the established criteria for definite diagnosis of a condition. Although a third of UCTDs can progress to a definite ARD within months or years, most UCTDs can remain stable for years with minimal disease activity. The annual incidence of UCTD in the general population ranges from 14 to 140 per 100 000 people...

Maternal vitamin B12 (B12) status has been inversely associated with adverse pregnancy outcomes and positively with fetal growth and infant development. South Asians, Canada's largest ethnic minority, are prone to B12 deficiency. Yet, data are lacking on B12 status in South Asian pregnant women in North America. We sought to determine B12 status, using multiple biomarkers, in 1st and 2nd trimester pregnant women of South Asian and, for comparison, European ethnicity living in Vancouver, Canada. In this retrospective cohort study, total B12, holotranscobalamin (holoTC), methylmalonic acid (MMA), and total homocysteine concentrations were quantified in two routinely collected (mean gestational week: 11·5 (range 8·3-13·9) and 16·5 (range 14·9-20·9)), banked serum samples of 748 healthy pregnant South Asian (n 371) and European (n 377) women...

AIMS/HYPOTHESIS: Roux-en-Y gastric bypass (RYGB) surgery is characterised by glycaemic variability. Prospective studies of glucose metabolism in pregnancy after RYGB are not available, therefore this study aimed to evaluate physiological alterations in glucose metabolism in pregnancy following RYGB. METHODS: Sixty-three pregnant women (25 who underwent RYGB, 19 non-operated obese control women and 19 normal weight control women) were included. Frequently sampled 3 h OGTTs and 1 h IVGTTs were performed between 24 and 28 weeks of gestation and, in a subgroup, were repeated at 3-6 months after delivery...

REVIEW

Although pre-eclampsia affects 5-10% of pregnancies globally and is responsible for substantial maternal and perinatal morbidity and mortality, currently there is no cure other than delivery of the baby. Predictive screening tests based on clinical risk factors, with or without the addition of biomarkers and imaging, have been developed, but adoption into clinical practice is limited by suboptimal test performance. Once established pre-eclampsia is diagnosed, a woman is usually managed expectantly prior to 37weeks' gestation to reduce perinatal morbidity and mortality associated with iatrogenic prematurity until maternal or fetal triggers for delivery mean that risks of pregnancy prolongation outweigh the benefits...

Maternal obesity increases placental transport of macronutrients, resulting in fetal overgrowth and obesity later in life. Choline participates in fatty acid metabolism, serves as a methyl donor and influences growth signaling, which may modify placental macronutrient homeostasis and affect fetal growth. Using a mouse model of maternal obesity, we assessed the effect of maternal choline supplementation on preventing fetal overgrowth and restoring placental macronutrient homeostasis. C57BL/6J mice were fed either a high-fat (HF, 60% kcal from fat) diet or a normal (NF, 10% kcal from fat) diet with a drinking supply of either 25 mM choline chloride or control purified water, respectively, beginning 4 weeks prior to mating until gestational day 12...

Restricted intrauterine fetal growth is an indicator of poor infant health outcomes. Classifying abnormal fetal growth, however, is challenging because there is no accepted definition of "normal" and "abnormal." Many standardized fetal growth curves have been created from populations of healthy pregnancies, excluding congenital abnormalities and, historically, have also excluded "non-white" women (Lubochenco, 1963, Pediatrics, 32: 793-800). More recently, assuming that ethnicity is a reliable, valid, and unchanging variable, customized growth charts have adjusted for ethnicity, in addition to maternal height, weight, and parity...

Preeclampsia is a form of hypertension-in-pregnancy (HTN-Preg) with unclear mechanism. Generalized reduction of uterine perfusion pressure (RUPP) could be an initiating event leading to uteroplacental ischemia, angiogenic imbalance, and HTN-Preg. Additional regional differences in uteroplacental blood flow could further affect the pregnancy outcome and increase the risk of preeclampsia in twin or multiple pregnancy, but the mechanisms involved are unclear. To test the hypothesis that regional differences in angiogenic balance and matrix metalloproteinases (MMPs) underlie regional uteroplacental vascularization and feto-placental development, we compared fetal and placental growth, and placental and myoendometrial vascularization in the proximal, middle and distal regions of the uterus (in relation to the iliac bifurcation) in normal pregnant (Preg) and RUPP rats...

Many studies have described an inverse relationship between birth weight and blood pressure (BP). Debate continues, however, over the magnitude and validity of the association. This analysis draws on the Early Determinants of Adult Health study (2005-2008), a cohort of 393 US adults (mean age 43 years; 47% male), including 114 same-sex sibling pairs deliberately sampled to be discordant on sex-specific birth weight for gestational age (BW/GA) in order to minimize confounding in studies of fetal growth and midlife health outcomes...

The amino acid arginine is a physiological precursor to nitric oxide, which is a key mediator of embryonic survival, fetal growth, and pregnancy maintenance. We evaluated the association between consumption of the amino acid arginine and the rate of adverse birth outcomes using data from a double-blind, randomized, placebo-controlled micronutrient supplementation trial among pregnant women in Dar es Salaam, Tanzania (2001-2004). Dietary intakes of arginine were assessed using repeated 24-hour recalls that were administered throughout pregnancy...

BACKGROUND: IGF2 is a key determinant of fetal growth, and altered expression of IGF2 is implicated in fetal growth disorders and maternal metabolic derangements including gestational diabetes. Here we studied how increased levels of IGF2 in late pregnancy affect fetal growth. METHODS: We employed a rat model of repeated intra-fetal IGF2 administration in late pregnancy, i.e. during GD19-GD21, and measured the consequences on fetal organ weight and expression of insulin/IGF-axis components...

Importance: Fetal umbilical vein aneurysm is an uncommon anomaly that accounts for approximately 4% of umbilical cord abnormalities. The rate of intrauterine fetal death is reported to be approximately 4% to 5%, higher than the background rate of 0.7% that is generally reported during pregnancy. Objective: The aim of this study was to review the pathophysiology, diagnosis, and clinical management of fetal umbilical vein aneurysm. Evidence Acquisition: Advances in high-resolution ultrasound combined with color Doppler and 3-dimensional rendering have contributed to an increased understanding of the fetal venous circulation in recent years...

Epidemiological studies have suggested a negative association between early life arsenic exposure and fetal size at birth, and subsequently with child morbidity and growth. However, our understanding of the relationship between arsenic exposure and morbidity and growth is limited. This paper aims to systematically review original human studies with an analytical epidemiological study design that have assessed arsenic exposure in fetal life or early childhood and evaluated the association with one or several of the following outcomes: fetal growth, birth weight or other birth anthropometry, infant and child growth, infectious disease morbidity in infancy and early childhood...
