The internal validity of the proposed Neurobehavioral Disorder Associated with Prenatal Alcohol Exposure (ND-PAE) was evaluated in children diagnosed with either Fetal Alcohol Syndrome (FAS) or partial FAS who were 3-10 years of age and had enrolled in a math intervention study. Symptoms were coded as present or absent using assessments conducted in the study, including standardized measures of neurocognitive and behavioral functioning, parent interview, and direct observations of the child. The number of endorsed ND-PAE symptoms was not related to environmental factors but was moderately related to the child's age...

Superfamily Hominoidea, which consists of Hominidae (humans and great apes) and Hylobatidae (gibbons), is well-known for sharing human-like characteristics, however, the genomic origins of these shared unique phenotypes have mainly remained elusive. To decipher the underlying genomic basis of Hominoidea-restricted phenotypes, we identified and characterized Hominoidea-restricted highly conserved noncoding sequences (HCNSs) that are a class of potential regulatory elements which may be involved in evolution of lineage-specific phenotypes...

Increased morbidity and fetal growth restriction are reported in uninfected children born to HIV-1-infected women treated with antiretroviral (ARV) therapy. Viruses and/or pharmacological interventions such as ARVs can induce metabolic stress skewing the cell's immune response and restricting (cell) growth. Novel metabolomic techniques provided the opportunity to investigate the impact of fetal HIV-1 and combination ARV therapy (cART)-exposure on the infants' immune-metabolome. Peroxidized lipids, generated by reactive oxygen species, were increased in cART/HIV-1-exposed infants, indicating altered mitochondrial functioning...

BACKGROUND: Over 5 million stillbirths and neonatal deaths occur annually. Limited and imprecise information on the cause of these deaths hampers progress in achieving global health targets. Complete diagnostic autopsies (CDAs)-the gold standard for cause of death determination-are difficult to perform in most high-burden settings. Therefore, validation of simpler and more feasible methods is needed. METHODS AND FINDINGS: In this observational study, the validity of a minimally invasive autopsy (MIA) method in determining the cause of death was assessed in 18 stillbirths and 41 neonatal deaths by comparing the results of the MIA with those of the CDA...

Chile allows abortion under no circumstances. Whether it's fetal anomaly incompatible with life or congenital malformation resulting in little or no life expectancy, all Chilean women are expected to carry their pregnancies to term. In this context, in January 2015 the Chilean Congress began debating a bill to legalize abortion on three grounds, including fatal congenital malformation. The medical community, including midwives, has presented its views for and against, especially on how the law may affect clinical practices; in addition, women, many of whom have experienced a fatal congenital malformation diagnosis, have weighed in...

OBJECTIVE: In patients with pre-gestational and gestational diabetes mellitus (GDM), insulin requirements often increase during the third trimester of pregnancy in order to maintain proper glycemic control. However, a fraction of patients demonstrate a significant decrease in insulin requirements in late gestation. We aimed to evaluate the clinical significance of decreasing insulin requirements in patients with pre-gestational diabetes and GDM with respect to fetal wellbeing and pregnancy outcome...

BACKGROUND: The weight of the infant at birth is a powerful predictor of infant growth and survival and is dependent on maternal health and nutrition during pregnancy. Pregnant women have a defense mechanism against increased oxidative stress composed of antioxidant enzymes and natural antioxidant vitamins like vitamin C and E. Therefore, we evaluated whether differences exist in serum levels of vitamin C and E in pregnant women complicated with intrauterine growth restriction (IUGR)...

Cancer and pregnancy rarely coincide. Gynecological cancers are among the most common malignancies to occur during pregnancy, and chemotherapy with or without surgery is the primary treatment option. The main concern of administering chemotherapy during pregnancy is congenital malformation, although it can be avoided by delaying treatment until after organogenesis. The dose, frequency, choice of chemotherapeutic agents, time of treatment commencement, and method of administration can be adjusted to obtain the best maternal treatment outcomes while simultaneously minimizing fetal toxicity...

Preeclampsia is manifested as maternal hypertension-in-pregnancy (HTN-Preg) and fetal growth restriction. Placental ischemia could be an initiating event; however, the molecular targets and intermediary mechanisms are unclear. We tested the hypothesis that placental ischemia could target vascular and uteroplacental matrix metalloproteinases (MMPs) through cytokines-mediated mechanism. MMP levels and distribution were measured in aorta, uterus and placenta of normal pregnant rats (Preg), and pregnant rats with reduced uterine perfusion pressure (RUPP)...

INTRODUCTION: Transplacental fetal glucose supply is predominantly regulated by glucose transporter-1 (GLUT1). Altered expression and/or function of GLUT1 may affect the intrauterine environment, which could compromise fetal development and may contribute to fetal programming. To date it is unknown whether placental GLUT1 is affected by preeclampsia, which is often associated with intrauterine growth restriction (IUGR). We addressed the hypothesis that preeclampsia leads to decreased expression and function of placental GLUT1...

INTRODUCTION: Intrauterine growth restriction (IUGR) and preeclampsia (PE) are pregnancy disorders characterized by placental insufficiency with oxygen/nutrient restriction and oxidative stress, all influencing mitochondria functionality and number. Moreover, IUGR and PE fetuses are predisposed to diseases later in life, and this might occur through epigenetic alterations. Here we analyze content and methylation of mitochondrial DNA (mtDNA), for the first time in IUGR and PE singleton fetuses, to identify possible alterations in mtDNA levels and/or epigenetic control of mitochondrial loci relevant to replication (D-loop) and functionality (mt-TF/RNR1: protein synthesis, mt-CO1: respiratory chain complex)...

INTRODUCTION: Fetal growth restriction (FGR) affects 5%-10% of all pregnancies, contributing to 30%-50% of stillbirths. Unfortunately, growth restriction often is not detected antenatally. The last weeks of pregnancy are critical for preventing stillbirth among babies with FGR because there is a pronounced increase in stillbirths among growth-restricted fetuses after 37 weeks of pregnancy. Here we present a protocol (V.1, 23 May 2016) for the RATIO37 trial, which evaluates an integrated strategy for accurately selecting at-risk fetuses for delivery at term...

BACKGROUND: Many stillbirths of normally-formed fetuses in the third trimester could be prevented via delivery if reliable means to anticipate this outcome existed. However, since the etiology of these stillbirths is often unexplained and, although the underlying mechanism is presumed to be hypoxia from "placental insufficiency", the placentas often appear normal on histopathologic examination. Gestational age is a risk factor for antepartum stillbirth, with a rapid rise in stillbirth rates after 40 weeks gestation...

β Cells are formed in embryonic life by differentiation of endocrine progenitors and expand by replication during neonatal life, followed by transition into functional maturity. In this study, we addressed the potential contribution of neuropeptide Y (NPY) in pancreatic β cell development and maturation. We show that NPY expression is restricted from the progenitor populations during pancreatic development and marks functionally immature β cells in fetal and neonatal mice and humans. NPY expression is epigenetically downregulated in β cells upon maturation...

The placenta is important in providing a healthy environment for the fetus and plays a central role in the pathophysiology of preeclampsia (PE). Fetal and placental developments are influenced by epigenetic programming. There is some evidence that PE is controlled to an altered circadian homeostasis. In a nested case-control study embedded in the Rotterdam Periconceptional Cohort, we obtained placental tissue, umbilical cord leukocytes (UCL), and human umbilical venous endothelial cells of 13 early-onset PE, 16 late-onset PE and 83 controls comprising 36 uncomplicated and 47 complicated pregnancies, i...

Congenital microcephaly, with or without additional developmental defects, is a heterogeneous disorder resulting from impaired brain development during early fetal life. The majority of causative genetic variants identified thus far are inherited in an autosomal recessive manner and impact key cellular pathways such as mitosis, DNA damage response and repair, apoptosis and splicing. Here, we report a novel donor splice site variant in the G-patch domain and KOW motifs (GPKOW) gene (NG_021310.2:g.6126G>A, NM_015698...

PURPOSE: Preterm birth (PTB) is a complex trait with strong genetic background, whose etiology is not fully understood. It was recently suggested that pregnancy duration is affected by fetal genetic variation even more than by the maternal genome. Vitamin D receptor (VDR) is involved in embryonic implantation and fertility. We studied the association between both maternal and neonatal vitamin D receptor (VDR) genetic variation and PTB. METHODS: Maternal and fetal (umbilical cord) DNA was isolated from Jewish Israeli idiopathic preterm newborns (24-36 weeks, n = 146) and control term newborns (>37 weeks, n = 229)...
