The aim of this observational cohort study was to specify the risk of the vitamin K antagonist (VKA) phenprocoumon during first trimester of pregnancy, in particular to estimate the risk of birth defects and spontaneous fetal loss. Four hundred eight pregnancies with phenprocoumon exposure were compared to 1,642 pregnancies neither exposed to VKA nor to other major teratogens or fetotoxicants. There was no typical warfarin embryopathy in our exposed cohort. However, the overall rate of major birth defects was significantly increased (7...

Reproductive-aged women with structural heart disease who become pregnant as well as postreproductive-aged women with this condition represent a significant proportion of patients seen by obstetrician- gynecologists. Usually, their conditions are complex, and a basic knowledge of the anatomy and physiology of the heart is required. Additionally, understanding the effect of pregnancy on women with structural heart disease is critically important to optimizing maternal and fetal outcomes. This monograph addresses the pathophysiology, signs and symptoms, screening and diagnosis, basic management, and suggested counseling for an obstetric-gynecologic patient with structural heart disease...

Congenital skeletal deformity of fetus varies and may be attributed to a range of reasons. Congenital skeletal deformity seriously affects body function or even leads to neonatal death directly. The disease brings great pain to victim and their family. We reviewed the fetal prenatal ultrasonic data conducted during period from Jan. 2013 to June 2016, and there were 84 fetuses with skeletal abnormalities among 12 000 cases, and 3 fetuses with thanatophoric dysplasia. Our report described and reviewed three common types of thanatophoric dysplasia, aiming to explore the value of standardized prenatal ultrasonic diagnosis of fetal abnormalities in the skeletal system...

Infection with Listeria monocytogenes during pregnancy is associated with miscarriage, preterm birth, and neonatal complications, including sepsis and meningitis. While the risk of these conditions is thought to be greatest during the third trimester of pregnancy, the determinants of fetoplacental susceptibility to infection, the contribution of gestational age, and the in vivo progression of disease at the maternal-fetal interface are poorly understood. We developed a nonhuman primate model of listeriosis to better understand antecedents of adverse pregnancy outcomes in early pregnancy...

Smoking represents perhaps the single most important health risk factor and a global contributor to mortality that can unquestionably be prevented. Smoking is responsible for many diseases, including various types of cancer, chronic obstructive pulmonary disease, coronary heart disease, peripheral vascular disease and peptic ulcer, while it adversely affects fetal formation and development. Since smoking habit duration is a critical factor for mortality, the goal of treatment should be its timely cessation and relapse prevention...

p62 is a scaffolding adaptor implicated in the clearance of protein aggregates by autophagy. Reactive oxygen species (ROS) can either stimulate or inhibit NFκB-mediated gene expression influencing cellular fate. We studied the effect of hydrogen peroxide (H2O2)-mediated oxidative stress and NFκB signaling on p62 expression in the retinal pigment epithelium (RPE) and investigated its role in regulation of autophagy and RPE survival against oxidative damage. Cultured human RPE cell line ARPE-19 and primary human adult and fetal RPE cells were exposed to H2O2-induced oxidative stress...

Zika virus (ZIKV) crosses the placenta and causes congenital disease. Here we develop an animal model utilizing direct ZIKV inoculation into the uterine wall of pregnant, immunocompetent mice to evaluate transplacental transmission. Intrauterine inoculation at embryonic day (E) 10, but not E14, with African, Asian or American strains of ZIKV reduces fetal viability and increases infection of placental and fetal tissues. ZIKV inoculation at E10 causes placental inflammation, placental dysfunction and reduces neonatal brain cortical thickness, which is associated with increased activation of microglia...

Intrauterine insults, such as poor nutrition and placental insufficiency, can alter cardiomyocyte development and this can have significant long-term implications for heart health. Consequently, epidemiological studies have shown that low birth weight babies have an increased risk of death from cardiovascular disease in adult life. In addition, intrauterine growth restriction can result in increased left ventricular hypertrophy, which is the strongest predictor for poor health outcomes in cardiac patients. The mechanisms responsible for these associations are not clear, but a suboptimal intrauterine environment can program alternative expression of genes such as cardiac IGF-2/H19, IGF-2R and AT1R through either an increase or decrease in DNA methylation or histone acetylation at specific loci...

Cas9-mediated, high-throughput, saturating in situ mutagenesis permits fine-mapping of function across genomic segments. Disease- and trait-associated variants identified in genome-wide association studies largely cluster at regulatory loci. Here we demonstrate the use of multiple designer nucleases and variant-aware library design to interrogate trait-associated regulatory DNA at high resolution. We developed a computational tool for the creation of saturating-mutagenesis libraries with single or multiple nucleases with incorporation of variants...

BACKGROUND/OBJECTIVES: Alterations in the L-arginine/nitric oxide (NO) metabolism contribute to diseases such as obesity, metabolic syndrome and airway dysfunction. The impact of early-life exposures on the L-arginine/NO metabolism in lung later in life is not well understood. The objective of this work was to study the effects of intrauterine exposures to maternal hyperglycemia and high-fat diet (HFD) on pulmonary L-arginine/NO metabolism in mice. METHODS: We used two murine models of intrauterine exposures to maternal (a) hyperglycemia and (b) HFD to study the effects of these exposures on the L-arginine/NO metabolism in lung in normal chow-fed offspring...

Diabetes is one of the most common metabolic disorders that may cause pathological pregnancy. Treating diabetes recognized during pregnancy results in lowering maternal and fetal complications. These patients present higher risk for excessive weight gain, preeclampsia, delivery with cesarean sections, high risk of developing type 2 diabetes and cardiovascular disease in the future. Fetuses of mothers with gestational diabetes are at higher risk for macrosomia and birth trauma, after delivery they present higher risk of developing neonatal hypoglycemia, hyperbilirubinemia, and respiratory distress syndrome...

Intrauterine growth restriction (IUGR) has been linked to heart disease in adulthood. This study aimed to examine the effect of gestational protein restriction during fetal and early postnatal life on the cardiac muscle structure and function in adult offspring. Pregnant female rats were randomly divided into two dietary groups: normal-protein diet (NP) and low-protein diet (LP). Fifteen male offspring from each group were included in the study. Offspring body weights were recorded at birth and monthly from weaning until 24 weeks of age while systolic blood pressure was measured weekly...

Pregnancy-related osteoporosis is a very rare condition characterized by the occurrence of fracture during pregnancy or the puerperium. Despite its relative rarity, it can be a dangerous condition that causes severe back pain, height loss and disability. Normal physiologic changes during pregnancy, genetic or racial difference, obstetrical history and obstetrical disease, such as preterm labor or pregnancy-induced hypertension, are presumed risk factors of pregnancy-related osteooporosis. However, exact etiology and pathogenesis are uncertain...

Tuberculosis (TB) remaining as one of the deadliest communicable diseases. Congenital infection by vertical transmission is rare but high neonatal mortality (up to 60%) and morbidity warrant early and accurate diagnosis of newborns suffering from TB. Intrauterine infection of tuberculosis is most commonly caused by haematogenous spread from the mother causing placental seedling. The organisms reach the fetus via the umbilical vein and the primary focus is often in the fetal liver in hematgenous spread. Another route of infection is by direct ingestion or aspiration of infected amniotic fluid if the placental caseous lesion ruptures directly into the amniotic cavity...

The objectives of the current experiment were to evaluate the effects of treating periparturient dairy cows with recombinant bovine somatotropin (rbST) on incidence of postpartum diseases and performance. Holstein (HO) and Jersey (JS) cows from 2 herds were enrolled in the experiment at 253 ± 3 d of gestation and assigned to the control (n = 432) and rbST125 (n = 437) treatments. Cows in the rbST125 treatment received 125 mg of rbST, weekly, from -21 to 21 d relative to calving. Blood sampled weekly, from -21 to 21 d relative to calving, from a subsample of cows was used to determine the concentrations of growth hormone (GH, HO = 106) and insulin-like growth factor 1 (IGF-1, HO = 147 and JS = 49)...

Maternal nutrition is one of the major determinants of pregnancy outcome. It has been suggested that reduced intakes or lack of specific nutrients during pregnancy influences the length of gestation, proper placental and fetal growth during pregnancy. Maternal nutrition, particularly micronutrients such as folate and vitamin B12, and long-chain polyunsaturated fatty acids (LCPUFA) are the major determinants of the one carbon cycle and are suggested to be at the heart of intrauterine programming of diseases in adult life...

Allergic inflammation is the result of a specific pattern of cellular and humoral responses leading to the activation of the innate and adaptive immune system, which, in turn, results in physiological and structural changes affecting target tissues such as the airways and the skin. Eosinophil activation and the production of soluble mediators such as IgE antibodies are pivotal features in the pathophysiology of allergic diseases. In the past few years, however, convincing evidence has shown that neurons and other neurosensory structures are not only a target of the inflammatory process but also participate in the regulation of immune responses by actively releasing soluble mediators...
