OBJECTIVE: To compare the anterior uterocervical angle and cervical length as predictors of spontaneous preterm delivery in patients with transvaginal cerclage. STUDY DESIGN: We retrospectively evaluated a cohort of 142 pregnant women with transvaginal cerclage placed over a 5-year period (2010 to 2015) were evaluated. Cervical morphology characteristics were measured from endovaginal imaging, including cervical length, cerclage height, funnel volume and anterior uterocervical angle prior to cerclage placement (UCA 1), shortly after cerclage placement (UCA 2) and the last image prior to delivery (UCA 3)...

CONTEXT: Glucocorticoids play a key role during intrauterine development in cellular growth and differentiation. Evidence suggests that exposure to inappropriate concentrations of glucocorticoids during sensitive developmental periods may produce alterations in physiological systems that impact obesity risk. OBJECTIVE: To elucidate the magnitude and stage-of-gestation specific association of maternal cortisol concentrations during pregnancy with infant adiposity...

REVIEW
Daniel Mureşan, Claudiu Mărginean, Gabriela Zaharie, Florin Stamatian, Ioana Cristina Rotar
Complete atrioventricular septal defect (CAVSD) is a fetal cardiac malformation (5% of all cardiac malformations) that can be detected prenatally with a reserved prognosis. The diagnosis can be suspected early at the end of the first trimester using the transabdominal or transvaginal ultrasound approach. Generally, the diagnostic can be established during the mid-trimester scan at 19-24 weeks of gestation. The percentage of antenatal diagnostic of CAVSD is between 57-92%. This review aims to analyze the anatomical principles and the ultrasound techniques that can improve the prenatal diagnosis of CAVSD...

: Zika virus (ZIKV) has emerged as a cause of congenital brain anomalies and a range of placental-related abnormalities, highlighting the need to unveil the modes of maternal-to-fetal transmission. The most likely route of vertical ZIKV transmission is via the placenta. The earliest events of ZIKV transmission in the maternal decidua, representing the maternal-uterine aspect of the chimeric placenta, have remained unexplored. Here we show that ZIKV replicates in first-trimester human maternal-decidual tissues grown ex-vivo as 3D organ cultures...

BACKGROUND: Several parameters including branch pulmonary artery (PA) diameters and Doppler-derived PA acceleration to ejection time ratio (AT/ET), late systolic-early diastolic reverse flow (PEDRF), and pulsatility index (PI) response to maternal hyperoxia have been used to investigate fetal pulmonary health. Shortened AT/ET, increased PEDRF and lack of PI response to hyperoxia have been observed in fetuses with severe lung hypoplasia and are considered markers of pulmonary vascular resistance...

OBJECTIVE: Birth weight (BW) is thought to be determined by maternal health, and genetic, nutritional and placental factors; the latter being influenced by anatomical development and perfusion. Maternal cardiovascular changes contribute to uteroplacental perfusion, however they have not been investigated in relation to fetal growth/BW. Our aim was to explore the relationship between maternal cardiovascular adaptation, fetal growth and BW in healthy pregnancies. METHODS: This was a longitudinal prospective study of women planning to conceive a pregnancy...

Siqing Nie, Jinhua Yu, Ping Chen, Yuanyuan Wang, Jian Qiu Zhang
Fetal nuchal translucency (NT) thickness is one of the most important parameters in prenatal screening. Locating the mid-sagittal plane is one of the key points to measure NT. In this paper, an automatic method for the sagittal plane detection using 3-D ultrasound data is proposed. To avoid unnecessary massive searching and the corresponding huge computation load, a model is proposed to turn the sagittal plane detection problem into a symmetry plane and axis searching problem. The deep belief network (DBN) and a modified circle detection method provide prior knowledge for the searching...

INTRODUCTION: Heavy episodic ("binge") drinking among women in Scotland is commonplace; prepregnancy drinking is associated with continued antenatal drinking. Evidence for effectiveness of standardized antenatal alcohol assessment is lacking. Alcohol-exposed pregnancies may be missed. We assessed peri-conceptual and mid-pregnancy consumption using a week-long retrospective diary and standard alcohol questionnaires, and evaluated the agreement between these instruments. MATERIAL AND METHODS: Cross-sectional study in two Scottish health board areas involving 510 women attending mid-pregnancy ultrasound scan clinics...

INTRODUCTION: The antenatal diagnosis of open spina bifida (OSB), a neural tube defect, is predominantly made at the second trimester morphology scan by ultrasound detection of structural abnormalities resulting from the associated Chiari II malformation. Evidence has emerged suggesting that these structural abnormalities can be detected earlier, by examination of the posterior fossa as part of the first trimester nuchal translucency scan. In particular, absence of the intra-cranial translucency (IT) of the fourth ventricle has shown promise as a diagnostic marker of OSB, although the sensitivity and specificity of this finding varies widely in the literature...

OBJECTIVES: In 2009, due to increasing congenital syphilis rates, prenatal syphilis tests (PST) at both mid-gestation and delivery were added to first trimester prenatal screening in the province of Alberta. We sought to determine the proportion of mothers who had all three recommended PSTs during this period and to identify factors associated with incomplete PST. METHODS: A cohort of all pregnancies resulting in a live or stillborn infant in Alberta for 2010 and 2011 was developed from Vital Statistics and linked with prenatal screening data to determine the number and timing of PSTs for pregnant women...

OBJECTIVE: Superimposed pre-eclampsia (SPE) is resolved only with the termination of the pregnancy. Therefore, the risk prediction and prevention is very important. We aimed to evaluate the characteristics of patients who develop SPE and their controllable risk factors during mid-trimester. DESIGN AND METHOD: A total of 283 pregnant women with chronic hypertension were included for the study. Blood pressure (BP) and body weight were recorded at 10, 20, 24, 28, and 32 weeks of gestation and pregnancy outcomes were evaluated...

OBJECTIVES: C-reactive protein (CRP) is a well-established general marker of inflammation from both infectious and noninfectious exposures. Previous studies have shown that maternal CRP is associated with an increased risk of autism and schizophrenia. The aim of this study was to examine the association between early to mid-gestational serum CRP levels, prospectively assayed in maternal sera, and the risk of bipolar disorder (BPD). METHODS: This study is derived from the Finnish Prenatal Study of Bipolar Disorder (FIPS-B), based on a nested case-control study design...

BACKGROUND: Hypertensive disorders in pregnancy may affect the cardiovascular risk of offspring. We examined the associations of maternal blood pressure throughout pregnancy and hypertensive disorders in pregnancy with childhood blood pressure of offspring. Specific focus was on the comparison with paternal blood pressure effects, the identification of critical periods, and the role of birth outcomes and childhood body mass index in the observed associations. METHODS AND RESULTS: This study was embedded in a population-based prospective cohort study among 5310 mothers and fathers and their children...
