OBJECTIVE: The objective of this study is to estimate associations between changes in maternal arterial pressure during normotensive pregnancies and offspring birth weight and body composition at birth. STUDY DESIGN: Prospective study of 762 pregnant normotensive Colorado women, recruited from outpatient obstetrics clinics. Repeated arterial pressure measurements during pregnancy were averaged within the second and third trimesters, respectively. Multivariable regression models estimated associations between second to third trimester changes in arterial pressure and small-for-gestational-age birth weight, fat mass, fat-free mass and percent body fat...

Background: Indications for surgery during pregnancy have increased. Specifically fetal interventions have increased from conditions that were considered lethal like twin-twin transfusion syndrome and severe fetal anemia to non-lethal conditions like myelomeningocele. The optimal anesthetic agent for in utero surgery is yet to be determined. Success of the procedure is often dictated by the efficacy of the anesthetic to immobilize the fetus without over-sedating mom. Remifentanil is used as preferred agent due to its short half-life however pharmacokinetics in pregnancy is unknown...

BACKGROUND: Obesity and being overweight are becoming epidemic, and indeed, the proportion of such women of reproductive age has increased in recent times. Being overweight or obese prior to pregnancy is a risk factor for gestational diabetes mellitus (GDM), and increases the risk of adverse pregnancy outcome for both mothers and their offspring. Furthermore, the combination of GDM with obesity/overweight status may increase the risk of adverse pregnancy outcome attributable to either factor alone...

We aimed to determine the maternal characteristics (demographics, an obstetric history, and prior cervical excisional procedure) associated with a short mid-trimester cervical length (CL, defined as a CL of ≤ 25 mm) and whether having a short cervix explains the association between these maternal characteristics and spontaneous preterm delivery (SPTD, defined as a delivery before 34 weeks). This is a single-center retrospective cohort study of 3,296 consecutive women with a singleton pregnancy who underwent routine CL measurement between 20 and 24 weeks...

Giuseppa Sciortino, Domenico Tegolo, Cesare Valenti
In this paper we propose a new methodology to support the physician both to identify automatically the nuchal region and to obtain a correct thickness measurement of the nuchal translucency. The thickness of the nuchal translucency is one of the main markers for screening of chromosomal defects such as trisomy 13, 18 and 21. Its measurement is performed during ultrasound scanning in the first trimester of pregnancy. The proposed methodology is mainly based on wavelet and multi resolution analysis. The performance of our method was analysed on 382 random frames, representing mid-sagittal sections, uniformly extracted from real clinical ultrasound videos of 12 patients...

OBJECTIVE: In comparison with standard two-dimensional (2D) imaging of fetal structure and biometry, we aimed to evaluate the role of three-dimensional (3D) imaging as a screening tool in the mid-trimester. STUDY DESIGN: Pregnant women presenting between 18and 22 weeks for routine anatomical survey and biometric measurements were recruited. Six volumes of fetal anatomic regions were obtained and archived for later reconstruction, along with three volumes of extra-fetal structures (placenta, cervix, amniotic fluid)...

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...

Objectives To examine associations between depression and preterm birth and small-for gestational age (SGA) among women of predominantly Puerto Rican descent, a population who experiences disparities in adverse birth outcomes and one of the highest infant mortality rates in the United States. Methods Proyecto Buena Salud (PBS) was a prospective cohort study conducted from 2006 to 2011 at a large tertiary care center in Western Massachusetts. Caribbean Islander (i.e., Puerto Rican and Dominican Republic) women were interviewed in early, mid and late pregnancy...

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 placenta-related abnormalities, highlighting the need to unveil the modes of maternal-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 three-dimensional (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 yet been investigated in relation to fetal growth or 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...

AIMS/HYPOTHESIS: The aim of this study was to prospectively and longitudinally investigate maternal iron status during early to mid-pregnancy, and subsequent risk of gestational diabetes mellitus (GDM), using a comprehensive panel of conventional and novel iron biomarkers. METHODS: A case-control study of 107 women with GDM and 214 controls (matched on age, race/ethnicity and gestational week during blood collection) was conducted within the the Eunice Kennedy Shriver National Institute of Child Health and Human Development Fetal Growth Studies-Singleton Cohort (2009-2013), a prospective and multiracial pregnancy cohort...

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...
