OBJECTIVE: The aim of the study is to assess the relationship between uteroplacental Doppler sonography findings and cerebral diffusion measured by diffusion-weighted magnetic resonance imaging (DWI) in fetuses with early- onset intrauterine growth restriction (IUGR). MATERIAL AND METHODS: The study included 54 pregnant women with fetal IUGR and 15 healthy controls (n: 15). Fetuses with IUGR were classified into 4 groups based on Doppler findings: group 1 (n = 12), umbilical artery (UA) pulsatility index (PI) >95pc; group 2 (n = 11), UA PI > 95 pc and middle cerebral artery PI <5pc; group 3 (n = 21), absent end-diastolic (A-EDF) in UA; group 4 (n = 10), reversed EDF in UA...

Early nutrition has critical influences on cardiovascular disease risk in adulthood. The study objectives were to evaluate the impact of low birth weight on fasting and postprandial lipid metabolism and endothelium function in Yucatan miniature pigs. Intrauterine growth-restricted (IUGR) piglets (n = 6, 3 d old, 0.73 ± 0.04 kg) were paired with normal weight (NW) same-sex littermates (n = 6, 1.11 ± 0.05 kg) and fed milk replacer ad libitum for 4 wk. Thereafter, all pigs were fed a standard diet ad libitum for 5 h/d with growth, intakes and blood samples collected for 8 mo...

Placental insufficiency is a primary cause of intrauterine growth restriction (IUGR). IUGR increases the risk of developing type 2 diabetes mellitus (T2DM) throughout life, which indicates that insults from placental insufficiency impair β-cell development during the perinatal period because β-cells have a central role in the regulation of glucose tolerance. The severely IUGR fetal pancreas is characterized by smaller islets, less β-cells, and lower insulin secretion. Because of the important associations among impaired islet growth, β-cell dysfunction, impaired fetal growth, and the propensity for T2DM, significant progress has been made in understanding the pathophysiology of IUGR and programing events in the fetal endocrine pancreas...

Structural changes within the placenta are observed in the course of pathological pregnancy. The aim of the study was to perform initial assessment of morphological features of placenta. The analysis was conducted by Scanning Electron Microscopy. Samples of placenta of women who delivered neonates appropriate for gestational age were characterized by a homogenous surface texture with natural corrugation. The surface of IUGR placenta from the group of mothers with pregnancy induced hypertension was definitely heterogeneous - noticeable swelling of tissue surface was observed...

Intrauterine growth restriction (IUGR) following prenatal hypoxia exposure leads to a higher risk of developing cardiovascular disease (CVD) in later life. Our aim was to evaluate cardiac susceptibility and its pathophysiological mechanisms following acute myocardial infarction (MI) in adult rat offspring exposed to prenatal hypoxia. Male and female rat offspring, which experienced normoxia (21% O2) or hypoxia (11% O2) in utero underwent sham or MI surgery at 12 weeks of age. Echocardiographic data revealed that both sexes had systolic dysfunction following MI surgery, independent of prenatal hypoxia...

Miscarriage and intrauterine growth restriction (IUGR) are devastating complications in fetal/neonatal alloimmune thrombocytopenia (FNAIT). We previously reported the mechanisms for bleeding diatheses, but it is unknown whether placental, decidual immune cells or other abnormalities at the maternal-fetal interface contribute to FNAIT. Here we show that maternal immune responses to fetal platelet antigens cause miscarriage and IUGR that are associated with vascular and immune pathologies in murine FNAIT models...

Intrauterine growth restriction (IUGR, a pregnancy complication where the fetus does not reach its genetic growth potential) is a leading cause of fetal morbidity and mortality with a significant impact on population health. IUGR is associated with gestational hypoxia; which can lead to placental oxidative stress and fetal programming of cardiovascular disease. Mitochondria are a major source of placental oxidative stress and may provide a therapeutic target to mitigate the detrimental effects of placental oxidative stress on pregnancy outcomes...

Allergy is a chronic disease that can develop as early as infancy, suggesting that early life factors are important in its aetiology. Variable associations between size at birth, a crude marker of the fetal environment, and allergy have been reported in humans and require comprehensive review. Associations between birth weight and allergy are however confounded in humans, and we and others have therefore begun exploring the effects of early life events on allergy in experimental models. In particular, we are using ovine models to investigate whether and how a restricted environment before birth protects against allergy, whether methyl donor availability contributes to allergic protection in IUGR, and why maternal asthma during pregnancy is associated with increased risks of allergic disease in children...

Normal pregnancy is a state of hypercoagulability with diminishing fibrinolytic activity, which is mainly caused by an increase of plasminogen activator inhibitor type 1 (PAI-1). PAI-1 is the main inhibitor of plasminogen activators, including tissue-type plasminogen activator (tPA) and urokinase-type plasminogen activator (uPA). In human placentas, PAI-1 is expressed in extravillous interstitial trophoblasts and vascular trophoblasts. During implantation and placentation, PAI-1 is responsible for inhibiting extra cellular matrix (ECM) degradation, thereby causing an inhibition of trophoblasts invasion...

BACKGROUND: Hypospadias is more common among male infants with growth restriction, defined as a birth weight less than the 10(th) centile, than in infants with a normal birth weight. Intrauterine growth retardation (IUGR) has been associated, also, with abnormalities of the placenta, such as maternal vascular malperfusion. In a consecutive sample of newborn infants, the association between hypospadias, IUGR and abnormalities of the placenta could be analyzed. METHODS: Affected infants were identified among 289,365 liveborn and stillborn infants in the Active Malformations Surveillance Program between 1972 and 2012...

Intrauterine growth restriction (IUGR) is when fetuses and newborn infants have not reached their true growth potential as genetically defined. Fetuses with IUGR develop in a less than ideal environment that leads to epigenetic changes and marks infants' metabolism for the rest of their lives. Epigenetic changes affect insulin-like growth factor-1 (IGF-1) levels and lead to insulin resistance and ultimately to a metabolic syndrome. The metabolic syndrome is a constellation of illnesses that raise one's risk for type 2 diabetes mellitus, coronary artery disease, and ischemic heart disease, including hypertension, dyslipidemia, central obesity, insulin resistance, and inflammation...

Hyperprolific sows have increased litter sizes but also result in more piglets that have been exposed to intrauterine growth restriction (IUGR). These IUGR piglets are likely to have a low rectal temperature and lower blood glucose levels compared with normal piglets at birth. Therefore, we hypothesized that a colostrum bolus at birth and/or heat from an external source would have a positive effect on blood glucose levels, rectal temperatures, and growth up to 8 h postpartum. In addition, liver glycogen and blood values at 8 h were investigated...
