PURPOSE: Our study objective is to examine the association between births conceived with assisted reproductive technology (ART) and birth defects using a large database from the United States. METHODS: Using the Centers for Disease Control and Prevention's Period-linked birth-infant death data files and fetal death database for 2011-2013, we conducted a retrospective cohort study comprised of live births that occurred in the USA during that time. Multivariate logistic regression was used to estimate the association between ART and birth defects, both overall and by specific defects...

Parvovirus B19 (B19V) has been discovered in 1975. The association with a disease was unclear in the first time after the discovery of B19V, but meanwhile, the usually droplet transmitted B19V is known as the infectious agent of the "fifth disease," a rather harmless children's illness. But B19V infects erythrocyte progenitor cells and thus, acute B19V infection in patients with a high erythrocyte turnover may lead to a life-threatening aplastic crisis, and acutely infected pregnant women can transmit B19V to their unborn child, resulting in a hydrops fetalis and fetal death...

Background: Fetal growth restriction (FGR) and low birth weight(LBW) are serious public health problems. In developing countries, the incidence of low birth weight is predominantly the result of FGR, and both low birth weight and FGR are associated with neonatal death and later growth and development. Fetal growth charts are important for assessing the size of the fetus during pregnancy. The aims of this study were to describe the fetal growth pattern of a population in rural Bangladesh where maternal undernutrition is prevalent and to compare the timing of FGR in that population with WHO and INTERGROWTH- 21st international reference values...

OBJECTIVES: Patients with severe left ventricular outflow tract obstruction often suffer from impaired left ventricular function, endocardial fibroelastosis and borderline-sized structures. The early Ross-Konno operation can offer complete repair due to outflow tract stenosis and enable the functional recovery and growth of small structures. METHODS: Between 2008 and March 2017, 44 early Ross-Konno procedures were performed at our centre. Thirty-five patients were neonates, and 9 were infants less than 3 months of age...

BACKGROUND: We investigated the associations between vitamin D status in early and late pregnancy with neonatal small for gestational age (SGA), low birth weight (LBW) and preterm delivery. Furthermore, associations between vitamin D status and pregnancy loss were studied. METHODS: Serum 25-hydroxyvitamin D (25OHD) was sampled in gestational week ≤ 16 (trimester 1 (T1), N = 2046) and > 31 (trimester 3 (T3), N = 1816) and analysed using liquid chromatography tandem mass spectrometry...

BACKGROUND & OBJECTIVES: Congenital Diaphragmatic Hernia (CDH) is associated with significant morbidity and mortality. This study compares the efficacy of the highest oxygenation index in the first 48 h (HiOI) versus current prenatal indices to predict survival and morbidity. METHODS: Medical records of 50 prenatally diagnosed, isolated, left-sided CDH patients treated from January 2011 to April 2016 were reviewed. Data abstracted included HiOI, lung to head ratio (LHR), observed to expected total fetal lung volume (O/E TFLV), percent liver herniation (%LH), 6 month survival, respiratory support at discharge, ventilator days and length of stay...

Polyglutamine (polyQ) diseases are a family of neurodegenerative disorders with very heterogeneous clinical presentations, although with common features such as progressive neuronal death. Thus, at the time of diagnosis patients might present an extensive and irreversible neuronal death demanding cell replacement or support provided by cell-based therapies. For this purpose stem cells, which include diverse populations ranging from embryonic stem cells (ESCs), to fetal stem cells, mesenchymal stromal cells (MSCs) or induced pluripotent stem cells (iPSCs) have remarkable potential to promote extensive brain regeneration and recovery in neurodegenerative disorders...

The presence of Waddlia chondrophila has been related to respiratory tract infections and human and animal fetal death. Although several sources of infection have been suggested, the actual source remains unknown and limited information exists on the prevalence of W. chondrophila in the environment. This pathogen has been previously detected in well water but its presence has not been confirmed in water networks. Since these bacteria have been detected in water reservoirs, it has been hypothesized that they can access artificial water systems and survive until they find appropriate conditions to proliferate...

Sudden unexpected perinatal collapse is a major trauma for the parents of victims. Sudden infant death syndrome (SIDS) is unexpected and mysterious death of an apparently healthy neonate from birth till 1 year of age without any known causes, even after thorough postmortem investigations. However, the incidence of sudden intrauterine unexplained death syndrome (SIUDS) is seven times higher as compared with SIDS. This observation is approximated 40-80%. Stillbirth is defined as death of a fetus after 20th week of gestation or just before delivery at full term without a known reason...

In the modern world, cardiovascular disease is a leading cause of death for both men and women. Epidemiologic studies consistently have suggested an association between low birthweight and/or fetal growth restriction and increased rate of cardiovascular mortality in adulthood. Furthermore, experimental and clinical studies have demonstrated that sustained nutrient and oxygen restriction that are associated with fetal growth restriction activate adaptive cardiovascular changes that might explain this association...

BACKGROUND: Early-onset fetal growth restriction represents a particular dilemma in clinical management balancing the risk of iatrogenic prematurity with waiting for the fetus to gain more maturity, while being exposed to the risk of intrauterine death or the sequelae of acidosis. OBJECTIVE: The Trial of Umbilical and Fetal Flow in Europe was a European, multicenter, randomized trial aimed to determine according to which criteria delivery should be triggered in early fetal growth restriction...

OBJECTIVE: The morphologic features of embryos with full trisomy 15 are described. METHOD: 1195 pregnancy losses were examined embryoscopically and cytogenetically. RESULTS: Of 1173 successfully karyotyped specimens, full trisomy 15 was diagnosed cytogenetically in 59 cases (5 %). All 59 trisomy 15 embryos were diagnosed cytogenetically in the group of 962 embryonic miscarriages (6%). Trisomy 15 was not registered in 171 anembryonic or yolk sac miscarriages, and no case of full trisomy 15 was observed in 62 fetal miscarriages...

When spinal roots are torn off from the spinal cord, both the peripheral and central nervous system get damaged. As the motoneurons lose their axons, they start to die rapidly, whereas target muscles atrophy due to the denervation. In this kind of complicated injury, different processes need to be targeted in the search for the best treatment strategy. In this study, we tested glial cell-derived neurotrophic factor (GDNF) treatment and fetal lumbar cell transplantation for their effectiveness to prevent motoneuron death and muscle atrophy after the spinal root avulsion and delayed reimplantation...

OBJECTIVE: To estimate the effect of 20-week abortion bans on maternal and consequent neonatal health outcomes and costs in the setting of fetal congenital diaphragmatic hernia. METHODS: A decision-analytic model was built using TreeAge software to evaluate the effect of a 20-week ban on abortion in a theoretical cohort of 921 women diagnosed with fetal congenital diaphragmatic hernia. Probabilities, utilities, and costs were derived from the literature. The cohort size was based on the annual rate of prenatal diagnoses of congenital diaphragmatic hernia and live births among the 20 states with bans...

Lymphopenia can result from various factors, including viral infections, clinical interventions, or as a normal property of the fetal/neonatal period. T cells in a lymphopenic environment undergo lymphopenia-induced proliferation (LIP) to fill the available "niche" as defined by peptide-MHC and homeostatic cytokine resources. We recently reported systemic autoimmunity following reconstitution of the lymphoid compartment of Rag1-/- mice with PD-1-/- hematopoietic stem cells or by transfer of thymocytes, but not splenocytes, suggesting that programmed death-1 (PD-1) plays a crucial role in controlling recent thymic emigrants (RTE) and preventing autoimmunity upon their LIP...

Preeclampsia (PE) is a pregnancy complex disease, distinguished by high blood pressure and proteinuria, diagnosed after the 20th gestation week. Depending on the values of blood pressure, urine protein concentrations, symptomatology, and onset of disease there is a wide range of phenotypes, from mild forms developing predominantly at the end of pregnancy to severe forms developing in the early stage of pregnancy. In the worst cases severe forms of PE could lead to systemic endothelial dysfunction, eclampsia, and maternal and/or fetal death...

Maternal morbidity, fetal mortality, and neonatal mortality are important indicators of maternal and child health. The study aimed to describe maternal and perinatal outcomes (low birth weight, prematurity, fetal and neonatal deaths, postpartum hospitalizations, and readmission of newborns) in a cohort of pregnant women whose deliveries were covered by the Brazilian Unified National Health System (SUS) in the city of São Paulo, Brazil, in the second semester of 2012. We obtained a retrospective cohort of 55,404 pregnant women with deterministic and probabilistic linkage of data from the Hospital Information System of the SUS (SIH/SUS), Information System on Live Births (SINASC), Mortality Information System (SIM), and National Registry of Health Establishments (CNES) databases...
