OBJECTIVE: Pregnancies in women affected by a muscular dystrophy are at an increased risk of adverse maternal and neonatal outcomes due to the effect of the disease on the muscular, cardiac and respiratory systems. We sought to evaluate the risk of adverse outcomes within a large population-based cohort study. METHODS: We used the data extracted from the Nationwide Inpatient Sample (NIS) to conduct a retrospective population-based cohort study consisting of over 12 million births that occurred in the United States between 1999 and 2013...

Endocrine disrupting chemicals are long suspected to impair reproductive health. Bisphenol A (BPA) has estrogenic activity and therefore the capacity of interfering with endocrine pathways. No studies dissected its short-term effects on pregnancy and possible underlying mechanisms. Here, we studied how BPA exposure around implantation affects pregnancy, particularly concentrating on placentation and uterine remodeling. We exposed pregnant female mice to 50 µg/kg BPA/day or 0.1% ethanol by oral gavage from day 1 to 7 of gestation...

Early life events are associated with the susceptibility to chronic diseases in adult life. Perturbations of endoplasmic reticulum (ER) homeostasis activate the unfolded protein response (UPR), which contributes to the development of metabolic alterations. Our aim was to evaluate liver UPR in an animal model of intrauterine growth restriction (IUGR). A significantly increased expression of X-box binding protein-1 spliced (XBP1s) mRNA (p<0.01), Endoplasmic Reticulum-localized DnaJ homologue (Erdj4) mRNA (p<0...

Intrauterine growth restriction (IUGR) and consumption of a high saturated fat diet (HFD) increase the risk of hypercholesterolemia, a leading cause of morbidity and mortality. The mechanism through which the cumulative impact of IUGR and in utero exposure to a maternal HFD increase cholesterol levels remains unknown. Cholesterol 7α hydroxylase (Cyp7a1) initiates catabolism of cholesterol to bile acids for elimination from the body, and is regulated by microRNA-122 (miR-122). We hypothesized that IUGR rats exposed to a maternal HFD would have increased cholesterol and decreased Cyp7a1 protein levels in juvenile rats, findings which would be normalized by administration of a miR-122 inhibitor...

Objectives: To study the recent trends in maternal and perinatal outcomes of triplet pregnancy from a perinatal centre in South India. Methods: All triplet pregnancies booked at Fernandez hospital, Hyderabad (a tertiary care perinatal centre in South India), or those referred between 2000 and 2014 were included in the study. The maternal, fetal and neonatal outcome and any interventions like cerclage, steroid administration were studied. Results: There were 82 triplet deliveries over the study period of 15 years (82 per 69,584 live births)...

BACKGROUND: Pregnancy-associated plasma protein-A2 (PAPP-A2) is consistently upregulated in the placentae of pregnancies complicated by preeclampsia and fetal growth restriction. The causes and significance of this upregulation remain unknown, but it has been hypothesized that it is a compensatory response to improve placental growth and development. We predicted that, if the upregulation of PAPP-A2 in pregnancy complications reflects a compensatory response, then deletion of Pappa2 in mice would exacerbate the effects of a gene deletion previously reported to impair placental development: deficiency of matrix metalloproteinase-9 (MMP9)...

The effects of intrauterine growth restriction (IUGR) extend well into postnatal life. IUGR is associated with an increased risk of adverse health outcomes, which often leads to greater medication usage. Many medications require hepatic metabolism for activation or clearance, but hepatic function may be altered in IUGR fetuses. Using a sheep model of IUGR, we determined the impact of IUGR on hepatic drug metabolism and drug transporter expression, both important mediators of fetal drug exposure, in late gestation and in neonatal life...

: Antithrombin is a major suppressor of thrombin, factor Xa and blood coagulation. Inherited antithrombin deficiency is rare and is considered among the common causes of inherited thrombophilia. The relationship between antithrombin and IUGR, is questionable. The aim of this study was to trace the relationship between antithrombin deficiency and the intrauterine weight reduction and neonatal morbidity. The study was conducted on 55 full-term neonates (including 25 baby boys and 30 baby girls), all were admitted to Neonatal Intensive Care Unit in Cairo University Hospitals with IUGR; and another 110 healthy full-term neonates as control group...

INTRODUCTION: The primary objective of the study was to evaluate the success of labor induction for indicated moderate and late preterm birth. As secondary objectives, the mode of delivery was assessed. MATERIAL AND METHODS: This is an observational study conducted in a tertiary care unit between 2013 and 2015. All patients who underwent labor induction for indicated preterm birth between 32 + 0 and 36 + 6 weeks of gestation (as premature rupture of membranes, preeclampsia, intrauterine growth restriction, fetomaternal alloimmunization, or intrahepatic cholestasis) were included...

BACKGROUND: A large recent study analyzed the relationship between multiple factors and neonatal outcome and in preterm births. Study variables included reason for admission, indication for delivery, optimal steroid use, gestational age and other potentially prognostic factors. Using stepwise multivariable analysis, the only two variables independently associated with serious neonatal morbidity were gestational age and the presence of suspected intrauterine growth restriction as a reason for admission...

INTRODUCTION: Currently there are no clinical screening tests available to identify pregnancies at risk of developing preeclampsia (PET) and/or intrauterine growth restriction (IUGR), both of which are associated with abnormal placentation. Metabolic profiling is now a stable analytical platform used in many laboratories and has successfully been used to identify biomarkers associated with various pathological states. METHODS: We used nuclear magnetic resonance spectroscopy (NMR) to metabolically profile serum samples collected from 143 pregnant women at 26-41 weeks gestation with pregnancy outcomes of PET, IUGR, PET IUGR or small for gestational age (SGA) that were age-matched to normal pre/term pregnancies...

INTRODUCTION: There is a need for prophylaxis to reduce placental-associated intrauterine growth restriction (IUGR). Pomegranate juice (PJ) is replete with phytochemicals having biological effects at non-pharmacological concentrations. We test the hypothesis that exposure of pregnant mice to hypoxia late in gestation induces cellular stress in the placenta, which can be ameliorated by antecedent maternal consumption of PJ. MATERIALS AND METHODS: We exposed pregnant mice to 12% or 21% oxygen, with food ad libitum or restricted, and with consumption of PJ or glucose between 12...

The increase in fetal and neonatal morbidity and mortality associated with twin pregnancies correlates with an increased risk of preterm delivery, low birth weight, and intrauterine growth restriction (IUGR). Although the pathogenesis of IUGR is unclear and thus management remains a major challenge, feto-placental blood vessels are compromised, and altered umbilical blood flow is observed. In this pilot observational study we investigated the effects of pravastatin plus l-arginine on umbilical artery (umb art) blood flow...

BACKGROUND: Low birthweight has been associated with a higher risk of hypertension, type 2 diabetes mellitus (T2D), and cardiovascular disease. The Barker hypothesis posits that intrauterine growth restriction resulting in lower birthweight is causal for these diseases, but causality is difficult to infer from observational studies. METHODS: We performed regression analyses to assess associations of birthweight with cardiovascular disease and T2D in 237 631 individuals from the UK Biobank...

Background: Achondrogenesis type IA (ACG1A) is a rare, lethal autosomal recessive chondrodysplasia affecting endochondral bone ossification and differentiation, causing intrauterine growth restriction, narrow thorax, and short limbs. Mutations in TRIP11 , which encodes Golgi microtubule-binding protein 210 in the Golgi apparatus, alter protein transport in tissues. Case presentation: A 28-week gestation male fetus was diagnosed with ACG1A by clinical, radiological, histologic, and molecular findings...

KEY POINTS: Gestational hypoxia represses TET1 expression in uterine arteries, which is recovered by inhibiting endogenous miR-210. Inhibition of miR-210 rescues BKCa channel expression and current in uterine arteries of pregnant animals acclimatized to high altitude hypoxia in a TET-dependent manner. MiR-210 blockade restores BKCa channel-mediated relaxations and attenuates pressure-dependent myogenic tone in uterine arteries of pregnant animals acclimatized to high altitude. ABSTRACT: Gestational hypoxia at high altitude has profound adverse effects on the uteroplacental circulation, and is associated with increased incidence of preeclampsia and fetal intrauterine growth restriction...

The syndromic diarrhea/trichohepatoenteric syndrome (SD/THE) is a rare and multi-system genetic disorder caused by mutation in SKIV2L or in TTC37 , two genes encoding subunits of the putative human SKI complex involved in RNA degradation. The main features are intractable diarrhea of infancy, hair abnormalities, facial dysmorphism, and intrauterine growth restriction. Immunologically this syndrome is associated with a hypogammaglobulinemia leading to an immunoglobulin supplementation. Our immune evaluation of a large French cohort of SD/THE patient revealed several immunological defects...

BACKGROUND: Assisted reproductive technologies (ART) are widely used to treat fertility issues in humans and for the production of embryos in mammalian livestock. The use of these techniques, however, is not without consequence as they are often associated with inauspicious pre- and postnatal outcomes including premature birth, intrauterine growth restriction and increased incidence of epigenetic disorders in human and large offspring syndrome in cattle. Here, global DNA methylation profiles in the trophectoderm and embryonic discs of in vitro produced (IVP), superovulation-derived (SOV) and unstimulated, synchronised control day 17 bovine conceptuses (herein referred to as AI) were interrogated using the EmbryoGENE DNA Methylation Array (EDMA)...

AIM: The effect that intrauterine or extrauterine growth restriction (EUGR) had on the build of very low birth weight (VLBW) infants was investigated before Japanese children started school. METHOD: Between 2005 and 2017 the National Hospital Organization, Saga, Japan, carried out pre-school checks on 322 children born with a VLBW at approximately six years of age. Growth restriction was defined as being born small for gestational age (SGA) or EUGR if they were born at term...

Taurine is regarded as an essential amino acid in utero, and fetal taurine supply is believed to rely solely on placental transfer from maternal plasma. Despite its potential role in intrauterine growth restriction and other developmental disturbances, human in vivo studies of taurine transfer between the maternal, placental, and fetal compartments are scarce. We studied placental transfer of taurine in uncomplicated human term pregnancies in vivo in a cross-sectional study of 179 mother-fetus pairs. During cesarean section, we obtained placental tissue and plasma from incoming and outgoing vessels on the maternal and fetal sides of the placenta...
