EGFL7 is a secreted, angiogenic factor produced by embryonic endothelial cells. To understand its role in placental development, we established a novel Egfl7 knockout mouse. The mutant mice have gross defects in chorioallantoic branching morphogenesis and placental vascular patterning. Microangiography and 3D imaging revealed patchy perfusion of Egfl7(-/-) placentas marked by impeded blood conductance through sites of narrowed vessels. Consistent with poor feto-placental perfusion, Egfl7 knockout resulted in reduced placental weight and fetal growth restriction...

BACKGROUND: A male fetus is suggested to be more susceptible to in utero and birth complications. This may be due in part to altered morphology or function of the XY placenta. We hypothesised that sexual dimorphism begins at the blastocyst stage with sex differences in the progenitor trophectoderm (TE) and its derived trophoblast lineages, as these cells populate the majority of cell types within the placenta. We investigated sex-specific differences in cell allocation in the pre-implantation embryo and further characterised growth and gene expression of the placental compartments from the early stages of the definitive placenta through to late gestation...

Insulin-like growth factor 2 (IGF2) is the major fetal growth hormone in mammals. We identify zinc finger protein 568 (ZFP568), a member of the rapidly evolving Kruppel-associated box-zinc finger protein (KRAB-ZFP) family linked primarily to silencing of endogenous retroelements, as a direct repressor of a placental-specific Igf2 transcript (designated Igf2-P0) in mice. Loss of Zfp568, which causes gastrulation failure, or mutation of the ZFP568-binding site at the Igf2-P0 promoter causes inappropriate Igf2-P0 activation...

BACKGROUND: Gestational weight gain above or below the 2009 Institute of Medicine guidelines has been associated with adverse maternal and neonatal outcomes. Although it has been well established that excess gestational weight gain is associated with the development of gestational hypertension and preeclampsia, the relationship between gestational weight gain and adverse perinatal outcomes among women with pregestational (chronic) hypertension is less clear. OBJECTIVE: The objective of this study was to examine the relationship between gestational weight gain above and below IOM guidelines and perinatal outcomes in a large, population-based cohort of women with chronic hypertension...

OBJECTIVES: To examine the association between sleep duration in early pregnancy and fetal growth in a prospective cohort study of 3567 Chinese women. METHODS: Pregnant women at 8-16 weeks of gestation were interviewed using a semi-quantitative questionnaire to assess sleep duration. Birth weight and birth length were measured by a midwife in the delivery room at birth; low birth weight (LBW) was defined as birth weight <2500 g and small for gestational age (SGA) was defined as <10th customized centile...

REVIEW
Tara Krishnan, Anna L David
Fetal growth restriction (FGR) is a serious pregnancy complication affecting ∼8% of all pregnancies. There is no treatment to increase fetal growth in the uterus. Gene therapy presents a promising treatment strategy for FGR, with the use of adenoviral vectors encoding for proteins such as vascular endothelial growth factor (VEGF) and insulin-like growth factor demonstrating improvements in fetal growth, placental function, and neonatal outcome in preclinical studies. Safety assessments suggest no adverse risk to the mother or fetus for VEGF maternal gene therapy; a clinical trial is in development...

BACKGROUND AND OBJECTIVE: Coffee and tea are commonly consumed during pregnancy. While several of their components, like caffeine, have strong pharmacological effects, the effect on the unborn fetus remains unclear. Caffeine intake has been associated with abortion, preterm birth and fetal growth restriction, but a general consensus on caffeine restriction is still lacking. We aimed to investigate antenatal coffee, tea and caffeine consumption and the effect on birth weight and length, gestational age at birth and hypertensive disorders in pregnancy...

Genetic variation in the oxytocin receptor gene (OXTR) is associated with several psychiatric conditions characterized by deficits in executive functioning (EF). A specific OXTR variant, rs2254298, has previously been associated with brain functioning in regions implicated in EF. Moreover, birth weight variation across the entire range is associated with individual differences in cortical structure and function that underlie EF. This is the first study to examine the main and interactive effect between rs2254298 and birth weight on EF in children...

The pathologies of the pregnancy complications pre-eclampsia (PE) and fetal growth restriction (FGR) are established in the first trimester of human pregnancy. In a normal pregnancy, decidual spiral arteries are transformed into wide diameter, non-vasoactive vessels capable of meeting the increased demands of the developing fetus for nutrients and oxygen. Disruption of this transformation is associated with PE and FGR. Very little is known of how these first trimester changes are regulated normally and even less is known about how they are compromised in complicated pregnancies...

BACKGROUND: Fetal adversity, evidenced by poor fetal growth for instance, is associated with increased risk for several diseases later in life. Classical cut-offs to characterize small (SGA) and large for gestational age (LGA) newborns are used to define long term vulnerability. We aimed at exploring the possible dynamism of different birth weight cut-offs in defining vulnerability in developmental outcomes (through the Bayley Scales of Infant and Toddler Development), using the example of a gene vs...

Head circumference (HC) is one of the most important biometrics in assessing fetal growth during prenatal ultrasound examinations. However, the manual measurement of this biometric by doctors often requires substantial experience. We developed a learning-based framework that used prior knowledge and employed a fast ellipse fitting method (ElliFit) to measure HC automatically. We first integrated the prior knowledge about the gestational age and ultrasound scanning depth into a random forest classifier to localize the fetal head...

For severe pre-eclampsia (PE) with fetal growth restriction (FGR), the only effective treatment is early delivery of the placenta. Clinicians are often forced to end the pregnancy because of maternal indications. We report a case of severe PE with FGR in which the PE was temporarily improved and pregnancy successfully prolonged with tadalafil, a phosphodiesterase 5 inhibitor. A 35-year-old primigravid woman presented at 27 3/7 weeks of gestation with severe PE and FGR. After commencing tadalafil administration, biochemical and angiogenic markers improved...

BACKGROUND: Inadequate or excessive total gestational weight gain (GWG) is associated with increased risks of small- and large-for-gestational age births, respectively, but evidence is sparse regarding overall and trimester-specific patterns of GWG in relation to these risks. Characterizing the interrelationship between patterns of GWG across trimesters can reveal whether the trajectory of GWG in the 1st trimester sets the path for GWG in subsequent trimesters, thereby serving as an early marker for at-risk pregnancies...

Preeclampsia is a leading cause of maternal and perinatal morbidity and mortality globally and proteinuria can be one of the cardinal features of this disease. However, studies about the association of the amount of proteinuria and the severity of preeclampsia, and perinatal outcomes are limited. Data on 239 women with preeclampsia were retrospectively collected from a university teaching hospital from September 2011 to June 2013 and analysed. Data included all clinical parameters and proteinuria in a 24h urine collection...

OBJECTIVE: To estimate whether pregnancy outcomes in women with severe preeclampsia (sPE) with small for gestational age (SGA) fetuses differ from those with sPE without SGA or isolated SGA. STUDY DESIGN: We conducted a retrospective cohort study of consecutive non-anomalous, livebirths in a single tertiary care institution from 2004 to 2008. We compared pregnancy outcomes in women who had sPE with SGA (birthweight<10th percentile), and sPE without SGA to those with isolated SGA as reference...

AbstractPregnant women and their developing fetuses are vulnerable to multiple environmental insults, including exposure to aflatoxin, a mycotoxin that may contaminate as much as 25% of the world food supply. We reviewed and integrated findings from studies of aflatoxin exposure during pregnancy and evaluated potential links to adverse pregnancy outcomes. We identified 27 studies (10 human cross-sectional studies and 17 animal studies) assessing the relationship between aflatoxin exposure and adverse birth outcomes or anemia...

Atrial fibrillation (AF) constitutes a relatively infrequent pregnancy complication, which may be a therapeutic Gordian knot. Indeed, sparse data exist regarding the prevalence, prognosis and management of AF during pregnancy. In general, AF occurs as a benign, self-limited arrhythmia but occasionally may have severe hemodynamic consequences in pregnant patients suffering from heart failure, congenital heart disease, or other comorbidities. Extra-cardiac causes of AF should always be meticulously excluded. Treatment decisions are difficult, since medications may cross placental barrier and potentially affect fetal growth and organogenesis or even result in fetal bradyarrhythmias...
