Nonreciprocal action of the parasympathetic (PNS) and sympathetic (SNS) nervous systems, increases susceptibility to emotional and behavioral problems in children exposed to adversity. Little is known about the PNS and SNS in interaction with early adversity during infancy. Yet this is when the physiological systems involved in emotion regulation are emerging and presumably most responsive to environmental influences. We examined whether parasympathetic respiratory sinus arrhythmia (RSA) and sympathetic pre-ejection period (PEP) response and recovery at six months, moderate the association between cumulative prenatal risk and physical aggression at 20 months (N=113)...

BACKGROUND: The mental health status of a pregnant woman and its consequent impact on foetal well being is not given much importance compared to the risk imposed by obstetric complications and medical conditions. Maternal psychological distress is a major public health problem and needs timely detection and intervention to prevent any adverse pregnancy outcome. There is ample evidence from literature that justifies the association of prenatal maternal mental stress and elevated cortisol with delayed infant motor and cognitive development; evidence from India being rather limited...

REVIEW
Zsofia Nemoda, Moshe Szyf
Major depressive disorder of the mother affects 6 to 17% of pregnancies worldwide and can lead to negative outcomes, such as preterm delivery and later mental health problems of the child. It has been proposed that developmental programming has long-lasting effects in the offspring that might be mediated by epigenetic mechanisms, such as DNA methylation. Altered stress regulation or impaired immunological function of the mother can potentially affect DNA methylation processes of the fetus, changing gene expression levels in utero...

Developmental exposure to prenatal stress (PS) and lead (Pb) can affect brain development and adversely influence behavior and cognition. Epigenetic-based gene regulation is crucial for normal brain development and mis-regulation, in any form, can result in neurodevelopmental disorders. Post-translational histone modifications (PTHMs) are an integral and dynamic component of the epigenetic machinery involved in gene regulation. Exposures to Pb and/or PS may alter PTHM profiles, promoting lifelong alterations in brain function observed following Pb±PS exposure...

Ovarian reserve has been suggested as an important contributing factor of reproductive success in bovine. Size of ovarian reserve is determined during fetal period and it could be altered by environmental factors, with which the dam is exposed. Maternal heat stress could impair placental function and fetal development; however, there is limited information on the impact of prenatal heat stress on fertility and ovarian reserve in the offspring. Therefore, a retrospective study was conducted, in which fertility parameters and AMH concentration, as a reliable marker of ovarian reserve in bovine, were studied in the offspring of dams that had been exposed to heat stress during the first (FTE), second (STE) or third (TTE) trimester of gestation and the offspring of dams unexposed to heat stress (US)...

Prenatal stress during pregnancy leads to sex-specific effects on fetal development and disease susceptibility over the life span; however, the origin of sex differences has not been identified. The placenta not only plays a key role in fetal growth and development throughout pregnancy, but also affects the fetal programming underlying subsequent adult health and accounts. Therefore, sex-specific adaptation of the placenta may be central to the sex differences in fetal growth and survival. Here, we analyzed the effects of prenatal dexamethasone (Dex) on sex-specific changes in placental gene expression using RNA-Seq...

Prenatal stress (PNS) might affect the developmental programming of adult chronic diseases such as metabolic and mood disorders. The molecular mechanisms underlying such regulations may rely upon long-term changes in stress-responsive effectors such as Brain-Derived Neurotrophic Factor (BDNF) that can affect neuronal plasticity underlying mood disorders and may also play a role in metabolic regulation. Based upon previous data, we hypothesized that PNS might lead to greater vulnerability to an obesogenic challenge experienced at adulthood...

The characterization and quantification of human dental enamel microstructure, in both permanent and deciduous teeth, allows us to document crucial growth parameters and to identify stressful events, thus contributing to the reconstruction of the past life history of an individual. Most studies to date have focused on the more accessible post-natal portion of the deciduous dental enamel, even though the analysis of prenatal enamel is pivotal in understanding fetal growth, and reveals information about the mother's health status during pregnancy...

The contribution of the early postnatal environment to the pervasive effects of prenatal alcohol exposure (PAE) is poorly understood. Moreover, PAE often carries increased risk of exposure to adversity/stress during early life. Dysregulation of immune function may play a role in how pre- and/or postnatal adversity/stress alters brain development. Here, we combine two animal models to examine whether PAE differentially increases vulnerability to immune dysregulation in response to early-life adversity. PAE and control litters were exposed to either limited bedding (postnatal day [PN] 8-12) to model early-life adversity or normal bedding, and maternal behavior and pup vocalizations were recorded...

Expanded carrier screening for autosomal-recessive conditions effectively identifies more carrier couples than traditional guideline-based carrier screening. However, clinically available expanded carrier screening panels include numerous conditions, some of which have questionable clinical utility as a result of very low carrier frequency, low or unknown testing sensitivity, and mild or incompletely penetrant phenotypes. Using the 2013 American College of Medical Genetics and Genomics Position Statement on Prenatal and Preconception Expanded Carrier Screening and the 2017 American College of Obstetricians and Gynecologists' Committee Opinion on Carrier Screening in the Age of Genomic Medicine as guidance, we propose specific criteria for the development of expanded carrier screening panels that will maximize clinical utility and minimize patient stress, unnecessary cost of follow-up testing, and clinician time spent facilitating and performing follow-up counseling and testing...

Little is known about relations between maternal prenatal stress and specific cognitive processes-learning and memory-in infants. A modified crib-mobile task was employed in a longitudinal design to test relations between maternal prenatal cortisol, prenatal subjective stress and anxiety, psychosocial variables, and learning and memory in 3- and 5-month-old infants. Results revealed that maternal prenatal cortisol was affected by particular psychosocial variables (e.g., maternal age, whether or not the infant's grandmother provided childcare, financial status), but was unrelated to measures of maternal depression, anxiety, and stress...

AIM: Maternal prenatal anxiety and stress (PNS) have been positively associated to physical health prob lems in offspring in the first year of life. Whether these associations are transient, persistent, or even progressive over time, is as yet unknown. The goal of this study is to investigate associations between late pregnancy PNS and child health from 18 months to age 6. METHODS: Mothers were recruited in late pregnancy, and had uncomplicated, singleton pregnancies without physical health problems...

There is significant heterogeneity amongst individuals with Autism Spectrum Disorder (ASD) in symptom presentation and severity. An understanding of the factors that contribute to and modulate symptom severity are critical to informing prognosis, stratification, and treatment decisions. Maternal prenatal stress exposure is a nonspecific risk factor for a wide array of neurodevelopmental outcomes in subsequent offspring. Emerging evidence suggests that prenatal maternal stress may increase ASD risk and contribute to variability in autism-like traits in the general population...

PURPOSE OF REVIEW: This review aims to provide a brief description of the complex etiology of autism spectrum disorders (ASD), with special emphasis on the recent findings of impaired redox control in ASD, and to suggest a possible model of oxidative stress-specific gene-environment interaction in this group of disorders. RECENT FINDINGS: Recent findings point out to the significance of environmental, prenatal, and perinatal factors in ASD but, at the same time, are in favor of the potentially significant oxidative stress-specific gene-environment interaction in ASD...

Development of the pulmonary circulation is a complex process with a spatial pattern that is tightly controlled. This process is vulnerable for disruption by various events in the prenatal and early postnatal periods. Disruption of normal pulmonary vascular development leads to abnormal structure and function of the lung vasculature, causing neonatal pulmonary vascular diseases. Premature babies are especially at risk of the development of these diseases, including persistent pulmonary hypertension and bronchopulmonary dysplasia...
