BACKGROUND: Schizophrenia is a common major mental disorder and prenatal nutritional deficiency may increase its risk. We aimed to investigate long-term impact of prenatal exposure to malnutrition on risk of schizophrenia in adulthood using the Chinese famine of 1959-1961 as a natural experiment. METHODS: We obtained data from the Second National Sample Survey on Disability implemented in 31 provinces in 2006, and restricted our analysis to 387,093 individuals born from 1956 to 1965...

Prenatal diagnosis of birth defects initially targeted Down syndrome and neural tube defects. Screening for fetal structural anomalies has expanded to screen any relevant malformation by means of a universal ultrasound scan. Although it is now apparent that clinically relevant genetic anomalies have a similar 3% birth prevalence, prenatal diagnosis programs still focus on Down syndrome. A new comprehensive paradigm is suggested, that provides information on all three groups of genetic disorders, chromosomal, submicroscopic and single-gene, causing intellectual and neurodevelopmental disability...

INTRODUCTION: Nutrition interventions may have favourable as well as unfavourable effects. The Maternal and Infant Nutrition Interventions in Matlab (MINIMat), with early prenatal food and micronutrient supplementation, reduced infant mortality and were reported to be very cost-effective. However, the multiple micronutrients (MMS) supplement was associated with an increased risk of stunted growth in infancy and early childhood. This unfavourable outcome was not included in the previous cost-effectiveness analysis...

Nicotine has been recognized to trigger various neuronal disabilities in the fetal brain and long-lasting behavioral deficits in offspring. However, further understanding of fetal brain development under nicotine exposure is challenging due to the limitations of existing animal models. Here, we create a new brain organoid-on-a-chip system derived from human induced pluripotent stem cells (hiPSCs) that allows us to model neurodevelopmental disorders under prenatal nicotine exposure (PNE) at early stages. The brain organoid-on-a-chip system facilitates 3D culture, in situ neural differentiation, and self-organization of brain organoids under continuous perfused cultures in a controlled manner...

BACKGROUND: Prenatal exposure to androgens during brain development in male individuals may participate to increase their susceptibility to develop neurodevelopmental disorders such as autism spectrum disorder (ASD) and intellectual disability. However, little is known about the action of androgens in human neural cells. METHODS: We used human neural stem cells differentiated from embryonic stem cells to investigate targets of androgens. RESULTS: RNA sequencing revealed that treatment with dihydrotestosterone (DHT) leads to subtle but significant changes in the expression of about 200 genes, encoding proteins of extracellular matrix or involved in signal transduction of growth factors (e...

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...

BACKGROUND: Late Language Emergence (LLE) in the first two years of life is one of the most common parental concerns about child development and reasons for seeking advice from health professionals. LLE is much more prevalent in twins (38%) than singletons (20%). In studies of language development in twins without overt disability, adverse prenatal and perinatal environments have been reported to play a lesser role in the etiology of LLE than adverse postnatal environments. However, there is a lack of population-level evidence about prenatal and perinatal risk factors for LLE in twins...

Importance: Fetal alcohol spectrum disorders are costly, life-long disabilities. Older data suggested the prevalence of the disorder in the United States was 10 per 1000 children; however, there are few current estimates based on larger, diverse US population samples. Objective: To estimate the prevalence of fetal alcohol spectrum disorders, including fetal alcohol syndrome, partial fetal alcohol syndrome, and alcohol-related neurodevelopmental disorder, in 4 regions of the United States...

Recently, American colleagues called for a systematic collection of anonymized data on how many embryos and foetuses are deselected per institution per year, and for which conditions. These authors argued that if this information would be reported to a government agency or international body, the information would provide a baseline against which jurisdiction-specific trends in selection could be assessed. People who have disabilities, together with other key stakeholders, laypeople and experts, would then be in a position, to assess the social impact of human selecting technologies and to make recommendations for action to mitigate negative effects as appropriate...

Mechanical birth-related injuries to the neonate are declining in incidence with advances in prenatal diagnosis and care. These injuries, however, continue to represent an important source of morbidity and mortality in the affected patient population. In the United States, these injuries are estimated to occur among 2.6% of births. Although more usual in context of existing feto-maternal risk factors, their occurrence can be unpredictable. While often superficial and temporary, functional and cosmetic sequelae, disability or even death can result as a consequence of birth-related injuries...

Maternal immune challenge has proved to induce moderate to severe behavioral disabilities in the offspring. Cognitive/behavioral deficits are supported by changes in synaptic plasticity in different brain areas. We have reported previously that prenatal exposure to bacterial LPS could induce inhibition of hippocampal long-term potentiation (LTP) in the CA1 area of the juvenile/adult male offspring associated with spatial learning inabilities. Nevertheless, deficits in plasticity could be observed at earlier stages as shown by the early loss of long-term depression (LTD) in immature animals...

Studies have shown a relationship between maternal periodontal diseases (PDs) and premature delivery. PDs are commonly encountered oral diseases which cause progressive damage to the periodontal ligament and alveolar bones, leading to loss of teeth and oral disabilities. PDs also adversely affect general health by worsening cardiovascular and metabolic diseases. Moreover, maternal PDs are thought to be related to increasing the frequency of preterm-birth with low birth weight (PBLBW) new-borns. Prematurity and immaturity are the leading causes of prenatal and infant mortality and is a major public health problem around the world...

This study aimed to estimate the disease burden of methylmercury for children born in Germany in the year 2014. Humans are mainly exposed to methylmercury when they eat fish or seafood. Prenatal methylmercury exposure is associated with IQ loss. To quantify this disease burden, we used Monte Carlo simulation to estimate the incidence of mild and severe mental retardation in children born to mothers who consume fish based on empirical data. Subsequently, we calculated the disease burden with the disability-adjusted life years (DALY)-method...

Contiguous microdeletions of the Norrie disease pseudoglioma (NDP) region on chromosome Xp11.3 have been widely confirmed as contributing to the typical clinical features of Norrie disease (ND). However, the precise relation between genotype and phenotype could vary. The contiguous deletion of NDP and its neighbouring genes, MAOA/B and EFHC2, reportedly leads to syndromic clinical features such as microcephaly, intellectual disability, and epilepsy. Herewe report a novel contiguous microdeletion of the NDP region containing the MAOB and EFHC2 genes,which causes eye defects but no cognitive disability...

BACKGROUND: Emerging work has examined neurodevelopmental outcomes following prenatal exposure to per- and polyfluoroalkyl substances (PFAS), but few studies have assessed associations with autism spectrum disorder (ASD). OBJECTIVES: Our objective was to estimate associations of maternal prenatal PFAS concentrations with ASD and intellectual disability (ID) in children. METHODS: Participants were from a population-based nested case-control study of children born from 2000 to 2003 in southern California, including children diagnosed with ASD ( n =553), ID without autism ( n =189), and general population (GP) controls ( n =433)...

During the last years, Down syndrome has been the focus of special attention. Down syndrome is a genetic disorder characterized by distinct physical features and some degree of cognitive disability. Patients with Down syndrome also present many other congenital anomalies. The mapping for phenotypes to specific regions of chromosome 21 permits to identify which genes (or small regions) contribute to the phenotypic features of Down syndrome and thus, to understand its pathogenesis. Mainly there are three cytogenetic forms of Down syndrome: free trisomy 21, mosaic trisomy 21 and robertsonian translocation trisomy 21...

Neural tube defects (NTDs) are congenital structural abnormalities of the central nervous system and vertebral column. Neural tube defects may occur as an isolated malformation, in combination with other malformations, as part of a genetic syndrome, or as a result of teratogenic exposure (1). Neural tube defects are the second-most-common major congenital anomaly (2) after cardiac malformations, and their prevalence varies by geographic region, race, and environmental factors (3). Outcomes and disabilities depend on level and extent of lesion; for instance, anencephaly is incompatible with life but most infants with spina bifida will survive after surgical repair (4)...

In a project The Hastings Center is now running on the future of prenatal testing, we are encountering clear examples, both in established law and in the practices of individual providers, of failures to respect women's reproductive autonomy: when testing is not offered to certain demographics of women, for instance, or when the choices of women to terminate or continue pregnancies are prohibited or otherwise not supported. But this project also raises puzzles for reproductive autonomy. We have learned that some clinicians and patients do not discuss the fact that prenatal testing can lead to a decision about whether to terminate a pregnancy-they just don't talk about it...
