    Using state and provincial surveillance programs to reduce risk of recurrence of neural tube defects in the United States and Canada: A missed opportunity?
    Birth Defects Res A Clin Mol Teratol 2016 Nov;106(11):875-880
    College of Public Health, University of South Florida, Tampa, Florida.
    Background: Once a woman has had a fetus or infant affected with a neural tube defect (NTD), the risk of recurrence is approximately 3%. This risk can be significantly reduced by folic acid supplement consumption during the periconceptional period; however, this requires women at risk to be adequately informed about the appropriate dosage and timing of supplement intake before planning another pregnancy. As birth defects surveillance programs are tasked with identifying and documenting NTD-affected pregnancies and births, they are in a unique position to support recurrence prevention activities.

    Acardiac twin pregnancies part III: Model simulations.
    Birth Defects Res A Clin Mol Teratol 2016 Dec 15;106(12):1008-1015. Epub 2016 Sep 15.
    Department of Biomedical Engineering & Physics, Academic Medical Center, University of Amsterdam, Amsterdam, The Netherlands.
    Background: Acardiac monochorionic twins lack cardiac function but grow by passive perfusion of the pump twin's deoxygenated arterial blood through placental arterioarterial (AA) and venovenous (VV) anastomoses and by hypoxia-mediated neovascularization. Pump twins therefore must continuously increase their cardiac output which may cause heart failure. Our aims were: to adapt our twin-twin transfusion syndrome model for acardiac twin pregnancies, to simulate pump and acardiac twin development, and to examine the model for early prognostic markers of pump twin survival.

Although genome-wide association studies (GWAS) have identified numerous risk variants, a considerable fraction of the genetic heritability remains unknown. The aim of the present study was to replicate a previous finding that de novo deletions in a 62 kb region of chromosome 7p14 are a risk factor for nsCL/P, using an independent cohort. Read More

    In utero exposure to venlafaxine, a serotonin-norepinephrine reuptake inhibitor, increases cardiac anomalies and alters placental and heart serotonin signaling in the rat.
    Birth Defects Res A Clin Mol Teratol 2016 Dec 7;106(12):1044-1055. Epub 2016 Jul 7.
    Department of Pharmacology and Therapeutics, McGill University, Montreal, QC, Canada.
    Background: Human studies are inconsistent with respect to an association between treatment with selective serotonin and serotonin-norepinephrine reuptake inhibitors (SSRI/SNRIs) and an increase in the incidence of congenital heart defects. Here we tested the hypothesis that in utero exposure to venlafaxine, a highly prescribed SNRI, increases the incidence of fetal heart defects and alters placental and fetal heart serotonin signaling in the rat.

    Methods: Timed-pregnant Sprague Dawley rats were gavaged daily with venlafaxine hydrochloride (0, 3, 10, 30, or 100 mg/kg/day) from gestation day 8 to 20. Read More

    Birth Defects Res A Clin Mol Teratol 2016 Sep 14;106(9):749-60. Epub 2016 Jun 14.
    Department of Pediatrics, USF Morsani College of Medicine, Tampa and St. Petersburg, Florida.
    Background: Embryonic acute exposure to ethanol (EtOH), lithium, and homocysteine (HCy) induces cardiac defects at the time of exposure; folic acid (FA) supplementation protects normal cardiogenesis (Han et al., , ; Serrano et al., ). Read More

    Prenatal diagnosis, hospital characteristics, and mortality in transposition of the great arteries.
    Birth Defects Res A Clin Mol Teratol 2016 Sep 14;106(9):739-48. Epub 2016 Jun 14.
    Department of Pediatrics, Baylor College of Medicine, Houston, Texas.
    Background: The role of prenatal diagnosis in reducing neonatal mortality from transposition of the great arteries (TGA) is controversial. Factors affected by prenatal diagnosis such as proximity at birth to a cardiac surgical center (CSC) and CSC volume are associated with mortality in congenital heart disease. The purpose of the study was to determine the associations between prenatal diagnosis, distance from birthplace to a CSC, CSC TGA volume, and neonatal mortality in patients with TGA. Read More

    Acardiac twin pregnancies part II: Fetal risk of chorangioma and sacrococcygeal teratoma predicted by pump/acardiac umbilical vein diameters.
    Birth Defects Res A Clin Mol Teratol 2016 Sep 7;106(9):733-8. Epub 2016 Jun 7.
    The Fetal Center at Children's Memorial Hermann Hospital, UT Health, McGovern Medical School, Houston, Texas.
    Background: We recently published pump/acardiac umbilical venous diameter (UVD) ratios, representing the pump twin's excess cardiac output fraction, of 27 acardiac twin pregnancies. There was a clear separation between the 17 pump twins that had life-threatening complications and the 10 that did not. The hypothesis of this study is that placental chorangioma and sacrococcygeal teratoma (SCT), tumors whose perfusion also causes high-output complications, have the same fetal outcome as pump twins when perfusion of the tumor requires the same excess cardiac output fraction. Read More

    Temporal trend in the reported birth prevalence of cleft lip and/or cleft palate in Brazil, 2000 to 2013.
    Birth Defects Res A Clin Mol Teratol 2016 Sep 3;106(9):789-92. Epub 2016 Jun 3.
    Department of Applied Oral Sciences, The Forsyth Institute, Cambridge, Massachusetts.
    Background: The birth prevalence of cleft lip with or without cleft palate (CL/P) in Brazil increased between the years from 1975 to 1994 but has not been evaluated for temporal trend since then.

    Methods: We used data from the Brazilian National Health Information System for the years 2000 through 2013. We calculated the reported CL/P birth prevalence each year per 10,000 live births and estimated the average increase in reported prevalence per year (and 95% confidence interval [CI]) by fitting a negative binomial regression model.
