Congenital hyperinsulinism is a serious blood glucose regulation defect that interferes with brain development, leading to mental retardation, neurological sequelae and secondary epilepsy and ultimately may be life-threatening. Congenital hyperinsulinism (CHI) is caused by genetic defects of regulation of insulin secretion that induce insulin oversecretion in intrauterine life and postnatally. The clinical consequence is fetal macrosomia and subsequently neonatal and infantile hypoglycaemia. The most severe form is caused by biallelic mutations of KCNJ11 and ABCC8 genes that encode both potassium channel subunits, whereas their heterozygous mutations as well as enzymatic defects (GLUD1, HADH, GCK) lead to milder presentation...

Diabetes, rare in the neonatal period, should be evoked in every newborn presenting with unexplained intrauterine and early postnatal growth retardation. This case report illustrates the clinical course and therapeutic approach of a newborn diagnosed with transient diabetes. The baby was born at 37 weeks of gestation with a severe intrauterine growth restriction. Except a mild macroglossia and signs of growth restriction, physical examination was normal. On the fifth day of life, hyperglycemia (180 mg/dl) was noted, and the next day, the diagnosis of diabetes was confirmed (high blood sugar, glucosuria, undetectable levels of insulin and C-peptide)...

OBJECTIVE: To investigate safety of hormonal contraception with regard to thromboembolic events in women with type 1 or 2 diabetes. RESEARCH DESIGN AND METHODS: We used data from 2002-2011 in Clinformatics Data Mart to identify women in the U.S., 14-44 years of age, with an ICD-9-CM code for diabetes and a prescription for a diabetic medication or device. We examined contraceptive claims and compared time to thromboembolism (venous thrombosis, stroke, or myocardial infarction) among women with diabetes dispensed hormonal contraception using a modification of Cox regression to control for age, smoking, obesity, hypertension, hyperlipidemia, diabetic complications, and history of cancer; we excluded data for 3 months after women gave birth...

OBJECTIVES: A high ratio of soluble fms-like tyrosine kinase-1 (sFlt-1) to placental growth factor (PlGF) has been linked with pre-eclampsia (PE). We evaluated the sFlt-1/PlGF ratio as a predictive marker for early-onset PE in women at risk of PE. METHODS: This prospective, Spanish, multicenter study included pregnant women with PE risk factors (including: history of intrauterine growth restriction; PE; eclampsia; hemolysis, elevated liver enzymes and low platelet count syndrome; pre-gestational diabetes; and abnormal uterine artery Doppler ultrasound)...

Several intrauterine environmental factors may increase the future risk of type 2 diabetes. The microbiome can influence the balance between health and disease. However, the influence of the maternal gut microbiome on the future risk of diabetes in the fetus is unknown. The present study investigated the associations between maternal gut microbiome and differentially methylated regions of diabetes-associated genes in umbilical cord samples. This study included 10 pregnant participants from a birth cohort study...

Emerging evidence suggests sex differences in the early origins of adult metabolic disease, but this has been little investigated in developing countries. We investigated sex-specific associations between low birth weight (LBW; <2.5 kg) and adult-onset diabetes in 12,525 participants from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Diabetes was defined by self-reported information and laboratory measurements. In confounder-adjusted analyses, LBW (vs. 2.5-4 kg) was associated with higher prevalence of diabetes in women (Prevalence Ratio (PR) 1...

BACKGROUND: Pregnancies complicated by maternal diabetes are associated with disproportionate intrauterine growth that subsequently may lead to pediatric adiposity. OBJECTIVES: We investigated whether disproportionate intrauterine growth leads to differences in BMI in 4- to 5-year-old offspring from pregnancies complicated by type 1 (ODM1), type 2 (ODM2), or gestational diabetes (OGDM). METHODS: Ultrasound data of fetal head-to-abdominal circumference (HC/AC) ratio obtained between 32 and 36 weeks of gestational age were related to offspring anthropometrics that were retrieved from infant welfare centers...

Gestational diabetes mellitus (GDM) has increased in recent years. Although the cellular and molecular mechanisms involved in GDM-increased risk factors to offspring remained poorly understood, some studies suggested an association between an increase in oxidative stress induced by maternal hyperglycemia and complications for both mothers and newborns. Here, we investigated the impact of maternal hyperglycemia followed by maternal insulin replacement during lactation on the expression of antioxidant enzymes and mast cell number in offspring ventral prostate (VP) at puberty...

Starting from the Developmental Origins of Health and Disease (DOHaD) hypotheses proposed by David Barker, namely fetal programming, in the past years, there is a growing evidence of the major role played by epigenetic factors during the intrauterine life and the perinatal period. Furthermore, it has been assessed that these factors can affect the health status in infancy and even in adulthood. In this review, we focus our attention on the fetal programming of the brain, analyzing the most recent literature concerning the epigenetic factors that can influence the development of neuropsychiatric disorders such as bipolar disorders, major depressive disorders, and schizophrenia...

The mechanism underlying the increased susceptibility of type 2 diabetes in offspring of maternal malnutrition is poorly determined. Here we tested the hypothesis that functional microRNAs (miRNAs) mediated the maternal low-protein (LP) isocaloric diet induced pancreatic β-cell impairment. We performed miRNA profiling in the islets from offspring of LP and control diet mothers to explore the potential functional miRNAs responsible for β-cell dysfunction. We found that LP offspring exhibited impaired glucose tolerance due to decreased β-cell mass and insulin secretion...

AIMS: Telomeres undergo shortening with cell division, accelerated by increased oxidative stress. We aimed to demonstrate shortened telomeres in the offspring of mothers who have diabetes as a consequence of exposure to increased oxidative stress during intrauterine development. METHODS: We examined the level of glycaemia (glucose, HbA1c, fructosamine), oxidative stress (lipid peroxidation) and the levels of antioxidant enzymes (Superoxide dismutase (SOD) and Selenium dependent glutathione peroxidase) and correlate these findings with mean telomere length (TL) in maternal and foetal blood in groups of pregnant women with pre-gestational diabetes (PGD), gestational diabetes (GD) and a euglycaemic control group...

Current evidence supports the notion that exposure to various environmental conditions in early life may induce permanent changes in the epigenome that persist throughout the life-course. This article focuses on early changes associated with obesity in adult life. A review is presented on the factors that induce changes in whole genome (DNA) methylation in early life that are associated with adult onset obesity and related disorders. In contrast, reversal of epigenetic changes associated with weight loss in obese subjects has not been demonstrated...

INTRODUCTION: Vaginal delivery is recommended after intrauterine fetal death. However, little is known about the risk of shoulder dystocia in these deliveries. We studied whether intrauterine fetal death increases the risk of shoulder dystocia at delivery. MATERIAL AND METHODS: In this population-based register study using the Medical Birth Registry of Norway, we included all singleton pregnancies with vaginal delivery of offspring in cephalic presentation in Norway during the period 1967-2012 (n = 2 266 118)...

BACKGROUND: Internationally, a typical model of maternity care is a medically led system with varying levels of midwifery input. New Zealand has a midwife-led model of care, and there are movements in other countries to adopt such a system. There is a paucity of systemic evaluation that formally investigates safety-related outcomes in relationship to midwife-led care within an entire maternity service. The main objective of this study was to compare major adverse perinatal outcomes between midwife-led and medical-led maternity care in New Zealand...

The placenta, which is a regulator organ for many metabolic activities between mother and fetus, is critical in influencing the outcome of pregnancy. Therefore, fetal growth is directly related to the placental development. Placental development depends on the coordinated action of trophoblast proliferation, differentiation and invasion. Studies on cell cycle related proteins that control these events are limited. Abnormal placental development is linked to various pregnancy pathologies such as preeclampsia, intrauterine growth restriction, diabetes mellitus and gestational trophoblastic diseases...

Unilateral or bilateral cryptorchidism is an isolated anomaly in the majority of cases, with evidence to date suggesting that it is a complex disorder resulting from interactions between genetic and environmental factors. Population, family, and limited genome-wide association data suggest moderate genetic risk, multiple susceptibility loci, and a role for the maternal environment. Epidemiologic studies have identified low birth weight or intrauterine growth retardation as factors most strongly associated with cryptorchidism, with additional evidence suggesting that maternal smoking and gestational diabetes increase risk...

Diabetes in pregnancy starts affecting the foetus even in the pre-conception period. The complications encountered in third trimester are foetal macrosomia and intrauterine foetal demise; birth of a macrosomic baby further leads to shoulder dystocia, birth trauma, brachial plexus injury. Additionally, pregnancies with overt/pregestational diabetes may be complicated with foetal growth restriction, congenital abnormalities diagnosed in third trimester and foetal hypertrophic obstructive cardiomyopathy. Even minor degrees of hyperglycaemia is associated with adverse pregnancy outcome...

The aim of the study was to investigate the role of diabetic intrauterine environment on circulating insulin, glucagon, and somatostatin levels in pregnant rats, fetuses, and offspring. Diabetes was induced in female Wistar rats by streptozotocin at birth or as adult and the animals were assigned into: control (C); mildly diabetic (MD); and severely diabetic (SD). The rats were mated and distributed into 2 subgroups: euthanasia at day 21 of pregnancy and at day 10 postpartum. Both MD and SD dams showed impaired oral glucose tolerance...
