Programming of hypothalamic functions regulating energy homeostasis may play a role in intrauterine growth restriction (IUGR)-induced adulthood obesity. The present study investigated the effects of IUGR on the hypothalamus proteome and metabolome of adult rats submitted to 50% protein-energy restriction throughout pregnancy. Proteomic and metabolomic analyzes were performed by data independent acquisition mass spectrometry and multiple reaction monitoring, respectively. At age 4 months, the restricted rats showed elevated adiposity, increased leptin and signs of insulin resistance...

BACKGROUND: Insulin resistance (IR) in adults has been associated with intrauterine growth restriction (IUGR). Leptin and adiponectin correlations with anthropometric parameters and IR at 72 h in discordant twins were tested. METHODS: We included 24 discordant (birth weight discordance ≥20% in relation to the heavier cotwin) and 30 concordant (birth weight discordance ≤10%) twins. RESULTS: A correlation between leptin (but not adiponectin) level and birth weight (BW), birth length and head circumference in IUGR twins was recorded (p<0...

BACKGROUND: Pre-eclampsia and placental causes of intrauterine growth restriction (IUGR) are part of the same spectrum of disorders. In IUGR, there is preferential shunting of blood to the fetal brain at the expense of other organs. We wanted to demonstrate that this also occurs in pre-eclampsia using three dimensional (3D) ultrasound. The 3D indices of perfusion are: flow index (FI), vascular index (VI) and vascularisation flow index (VFI) which reflect tissue vascularity and flow intensity...

Epithelial membrane protein-2 (EMP2) is a tetraspan protein predicted to regulate placental development. Highly expressed in secretory endometrium and trophectoderm cells, previous studies suggest that it may regulate implantation by orchestrating the surface expression of integrins and other membrane proteins. In order to test the role of EMP2 in pregnancy, mice lacking EMP2 (Emp2(-/-) ) were generated. Emp2(-/-) females are fertile but have reduced litter sizes when carrying Emp2(-/-) but not Emp2(+/-) fetuses...

INTRODUCTION: 1Intrauterine growth restriction (IUGR) is the failure of the fetus to achieve its inherent growth potential, and it has frequently been associated with neurodevelopmental problems in childhood. Neurological disorders are mostly associated with IUGR babies with an abnormally high cephalization index (CI) and a brain sparing effect. However, a similar correlation has never been demonstrated in an animal model. The aim of this study was to determine the correlations between CI, functional deficits in learning and memory and alterations in synaptic proteins in a rat model of IUGR...

PURPOSE: Meconium-stained amniotic fluid (MSAF) is rarely observed in preterm pregnancies, and its clinical significance is undetermined. We evaluated the correlation between MSAF and obstetrical and perinatal complications prior to 34 weeks' gestation. MATERIALS AND METHODS: Pregnancies complicated with MSAF between 24 and 34 weeks of gestation were compared with same gestational age-matched controls. The variables measured were: obstetrical complications: clinical chorioamnionitis, Intrahepatic Cohlestasis of Pregnancy - ICP, Intra Uterine Growth Restriction - IUGR, preeclampsia, gestational diabetes; nonobstetrical complications; and perinatal complications: cord around neck/body, Apgar <7 at 5 min, cord pH, Neonatal Intensive Care Unit - NICU admission, complications during NICU hospitalization, and composite outcome...

BACKGROUND: Some studies suggest a relationship between maternal smoking during pregnancy and not only intrauterine fetal growth restriction or low birth weight, but also with changes in the postnatal growth and development. The objective of the present study was to investigate the effects of smoking during pregnancy on infants growth in the first 6 months of life compared with a control group and a group with idiopathic intrauterine growth restriction. METHODS: Longitudinal observational study using a convenience sample of newborns divided into three groups: infants of smoking mothers (tobacco), with idiopathic intrauterine growth restriction (IUGR) and a control group...

The onset of fetal pathologies can be screened during pregnancy by means of Fetal Heart Rate (FHR) monitoring and analysis. Noticeable advances in understanding FHR variations were obtained in the last twenty years, thanks to the introduction of quantitative indices extracted from the FHR signal. This study searches for discriminating Normal and Intra Uterine Growth Restricted (IUGR) fetuses by applying data mining techniques to FHR parameters, obtained from recordings in a population of 122 fetuses (61 healthy and 61 IUGRs), through standard CTG non-stress test...

BACKGROUND: Counseling for patients with impending premature delivery has been traditionally based primarily on the projected gestational age at delivery. There are limited data regarding how the indications for the preterm birth affect the neonatal outcome and whether this issue should be taken into account in decisions regarding management and patient counseling. OBJECTIVE: We performed a prospective study of pregnancies resulting in premature delivery at less than 32 weeks to determine the influence of both the Indications for Admission and their associated Indications for Delivery on neonatal mortality and complications of prematurity...

Background. Takayasu's arteritis (TA) is a rare, chronic, inflammatory, progressive, idiopathic arteriopathy, afflicting young women of reproductive age group, causing narrowing, occlusion, and aneurysms of systemic and pulmonary arteries, especially the aorta and its branches. During pregnancy, such patients warrant special attention. An interdisciplinary collaboration of obstetricians, cardiologists, and neurologists is necessary to improve maternal and fetal prognosis. Here a case is reported where a patient with diagnosis of TA, complicated by neurological sequelae, successfully fought the vagaries of the condition twice to deliver uneventfully...

OBJECTIVE: Fetuses with intrauterine growth restriction (IUGR) have adaptive hormonal changes including changes in insulin, which may increase their future risks for developing diabetes mellitus. This study compared cord blood insulin concentrations in IUGR and appropriate for gestational age (AGA) fetuses in a monochorionic (MC) twin model. MATERIALS AND METHODS: Ten pairs were classified as selective IUGR (sIUGR) based on having one twin weight below the 10th percentile and with an intertwin birth weight discordance>20%...

OBJECTIVE: This study investigated the role of oxidative damage and nitric oxide (NO) synthases in the fetal heart using a model of intrauterine growth restriction (IUGR) induced by uteroplacental circulation restriction (UCR). METHODS: New Zealand white rabbits kept under 12 hr light cycles, with food and water provided ad libitum, were subjected at day 25 of pregnancy to 40%-50% uteroplacental artery ligation. We analyzed the gene expression of enzymes linked to nitric oxide synthesis (iNOS, eNOS, HO-1, and ARG-2), HIF-1α and the state of oxidative stress (protein carbonyl levels) in fetal heart homogenates...

BACKGROUND: Intra-uterine growth restriction (IUGR) and fetal overgrowth increase risks to postnatal health. Maternal nutrition is the major intrauterine environmental factor that alters fetal weight. However, the mechanisms underlying the effects of maternal nutrition on fetal development are not entirely clear. We developed a pig model, and using isobaric tags for relative and absolute quantification (iTRAQ), we investigated alterations in the placental proteome of gilts on a normal-energy-intake (Con) and high-energy-intake (HE) diet...

The teratogenic mechanisms triggered by ZIKV are still obscure due to the lack of a suitable animal model. Here we present a mouse model of developmental disruption induced by ZIKV hematogenic infection. The model utilizes immunocompetent animals from wild-type FVB/NJ and C57BL/6J strains, providing a better analogy to the human condition than approaches involving immunodeficient, genetically modified animals, or direct ZIKV injection into the brain. When injected via the jugular vein into the blood of pregnant females harboring conceptuses from early gastrulation to organogenesis stages, akin to the human second and fifth week of pregnancy, ZIKV infects maternal tissues, placentas and embryos/fetuses...

Intrauterine growth restriction (IUGR) is one of the most common causes of perinatal mortality and morbidity. White matter and neuronal injury are major pathophysiological features of the IUGR neonatal brain. GABAA (γ-aminobutyric acid type A) receptors have been shown to play a role in oligodendrocyte differentiation and proliferation in the neonatal brain and may be a key factor in white matter injury and myelination in IUGR neonates. Whether there are impairments to the GABAergic system and neuronal cytoskeleton in IUGR brain has yet to be elucidated...
