OBJECTIVE: To explore the outcome of monochorionic (MC) twin pregnancies affected by selective intra-uterine growth restriction (sIUGR) according to the umbilical artery Doppler pattern of the smaller twin. METHODS: Medline, Embase, Cinhal and ClinicalTrials.gov databases (2000-2016) were searched. sIUGR was defined as the presence of one twin with estimated fetal weight and/or abdominal circumference less than 10(th) or 5(th) percentile and classified according to the umbilical artery Doppler flow pattern of the smaller twin (type I: persistently positive, type II: persistently absent/reversed, type III: intermittently absent/reversed)...

BACKGROUND: The association of early maternal birthing age with smaller children has been widely observed. However, it is unclear if this is due to confounding by factors such as socioeconomic status, or the age at which child growth restriction first occurs. OBJECTIVE: To examine the effect of early maternal birthing age on the first-born child's height-for-age in a sample of developing countries in Africa, Asia, and Latin America. DESIGN: Cross-sectional data from Demographic Health Surveys from 18 countries were used, to select the first-born child of mothers aged 15-24 years and a range of potential confounding factors, including maternal height...

PURPOSE OF REVIEW: Selective intrauterine growth restriction (sIUGR) in twin pregnancies presents a complex management problem for the fetal medicine specialist. This review summarizes what is currently known about sIUGR pathophysiology, particularly in monochorionic pregnancies and looks at the results of early trials of fetal intervention in high-risk sIUGR pregnancies. RECENT FINDINGS: sIUGR in monochorionic pregnancies is due to unequal placental sharing, but the clinical outcome is determined by the characteristics of the placental vascular anastomoses...

Rats with intrauterine growth retardation and catch-up growth (CG-IUGR) after birth show increased susceptibility to diabetes mellitus in adulthood. The expression of glucose transporter type 4 (GLUT4) decreases in female IUGR offspring rats with seminutrient restriction during pregnancy. However, the male CG-IUGR rats also display an increased susceptibility to diabetes mellitus in adulthood. Whether there is another factor, besides GLUT4, in male CG-IUGR rat that mediates their susceptibility to diabetes mellitus? The male IUGR rats with catch-up growth were selected as the research objects...

BACKGROUND: Although this is beginning to change, the content of antenatal care has been relatively neglected in safe-motherhood program efforts. This appears in part to be due to an unwarranted belief that interventions over this period have far less impact than those provided around the time of birth. In this par, we review available evidence for 21 interventions potentially deliverable during pregnancy at high coverage to neglected populations in low income countries, with regard to effectiveness in reducing risk of: maternal mortality, newborn mortality, stillbirth, prematurity and intrauterine growth restriction...

BACKGROUND: Some disorders of pregnancy and newborn have been associated with vitamin D deficiency (25 (OH) D) in maternal serum. The pathophysiology of this relationship is unknown today. OBJECTIVE: The aim of this study was to determine whether serum levels of vitamin D at the beginning of pregnancy are associated with gestational diabetes, hypertensive disorders of pregnancy, preterm birth and fetal growth restriction. MATERIAL AND METHOD: We conducted a prospective cohort study in 370 pregnant women at low obstetric risk randomly selected in our area (latitude 42 ° 20'N)...

For clinical management of different forms of psychosis, both classical and atypical anti-psychotic drugs (APDs) are available. These drugs are widely prescribed, even during pregnancy considering their minimal extra-pyramidal side effects and teratogenic potential compared to classical APDs. Among AAPDs, risperidone (RIS) is a first-line drug of choice by physicians. The molecular weight of RIS is 410.49 g/mol; hence, it can easily cross the placental barrier and enter the foetal bloodstream. It is not known whether or not AAPDs like RIS may affect the developing placenta and foetus adversely...

Intrauterine growth restriction (IUGR) is a condition which has been difficult to assess at an early stage, resulting in the delivery of children who have poor genetic growth potential. Currently, IUGR classification is based upon the system of ultrasound biometry. Doppler velocimetry allows the measurement of hemodynamic flow of major fetal vessels, comparing the flow indices and patterns of normal and IUGR cases. In this review, the effectiveness of Doppler velocimetry in assessing blood flow in major vessels including the umbilical artery, ductus venosus, and middle cerebral artery was studied for both diagnostic and prognostic screening of IUGR...

INTRODUCTION: Intrauterine growth restriction has been associated with exposure to air pollution, but there is a need to clarify which sources and components are most likely responsible. This study investigated the associations between low birth weight (LBW, <2500g) in term born infants (≥37 gestational weeks) and air pollution by source and composition in California, over the period 2001-2008. METHODS: Complementary exposure models were used: an empirical Bayesian kriging model for the interpolation of ambient pollutant measurements, a source-oriented chemical transport model (using California emission inventories) that estimated fine and ultrafine particulate matter (PM2...

Hypoxia is the primary stimulus for the production of erythropoietin (EPO) in both fetal and adult life. Here, we investigated fetal plasma EPO concentrations in monochorionic (MC) twin pregnancies with selective intrauterine growth restriction (sIUGR) and abnormal umbilical artery (UA) Doppler. We diagnosed sIUGR in presence of (1) birth-weight discordance >20% and (2) either twin with a birth weight <10th percentile. An abnormal UA Doppler was defined as a persistent absent-reverse end diastolic flow (AREDF)...
