Background: Fetal alcohol spectrum disorder (FASD) is a developmental disorder that manifests through a range of cognitive, adaptive, physiological, and neurobiological deficits resulting from prenatal alcohol exposure. Although the North American prevalence is currently estimated at 2-5%, FASD has proven difficult to identify in the absence of the overt physical features characteristic of fetal alcohol syndrome. As interventions may have the greatest impact at an early age, accurate biomarkers are needed to identify children at risk for FASD...

AIM: Studies are increasingly focusing on the effects of prenatal alcohol exposure (PAE) on child health. The aim of this review was to provide paediatricians with new insights to help them communicate key messages about avoiding alcohol during pregnancy. METHODS: Inspired by the 7th International Conference on Fetal Alcohol Spectrum Disorder, which focused on integrating research, policy and practice, we studied English language papers published since 2010 on how early PAE triggered epigenetic mechanisms that had an impact on the development of some chronic diseases...

Fetal Alcohol Spectrum Disorders (FASD) might be 10-15 times more prevalent among foster/adopted children compared to the general population; however, many of these children remain undiagnosed or misdiagnosed. The lack of confirmed prenatal alcohol exposure (PAE) may be a key barrier to diagnosis. Our sample included 681 patients evaluated for FASD, according to the University of Washington 4-Digit Diagnostic Code, at a pediatric specialty clinic. Guardianship status and other patient characteristics were evaluated by multinomial logistic regression as potential predictors of being classified into one of the following FASD groups: 1) full or partial Fetal Alcohol Syndrome (FAS/pFAS; n = 97); 2) Static Encephalopathy/Alcohol-Exposed (SE/AE) or Neurobehavioral Disorder/Alcohol-Exposed (ND/AE) (n = 135); and 3) some features of FASD (equivalent to pFAS, SE/AE or ND/AE phenotypes) but unknown PAE (n = 449)...

BACKGROUND: We have reported that prenatal alcohol exposure (PAE)-induced deficits in dentate gyrus, long-term potentiation (LTP), and memory are ameliorated by the histamine H3 receptor inverse agonist ABT-239. Curiously, ABT-239 did not enhance LTP or memory in control offspring. Here, we initiated an investigation of how PAE alters histaminergic neurotransmission in the dentate gyrus and other brain regions employing combined radiohistochemical and electrophysiological approaches in vitro to examine histamine H3 receptor number and function...

BACKGROUND: Clinical studies show that prenatal alcohol exposure (PAE) results in effects that persist into adulthood. Experimental animal models of moderate PAE demonstrate that young adults with PAE display potentiated sensitivity to light touch, clinically termed allodynia, following sciatic nerve chronic constriction injury (CCI) that coincides with heightened spinal glial, spinal macrophage, and peripheral immune responses. However, basal touch sensitivity and corresponding glial and leukocyte activation are unaltered...

Many functions of the hippocampus are affected by prenatal alcohol exposure (PAE). In particular, dysregulation of the stress response is especially important because individuals with PAE carry increased risks for exposure to stressful environments throughout life. Little is known, though, about how adolescent stress in the context of PAE-related stress system dysregulation may further alter hippocampal development. Here we investigate the short- and long-term effects of adolescent chronic mild stress (CMS) on mRNA expression of stress-related mineralocorticoid (MR), glucocorticoid (GR), and type 1 CRH (CRHR1) receptors in the dorsal and ventral hippocampal formation of PAE and control rats...

Purpose: Fetal alcohol spectrum disorder (FASD) is a developmental disease characterized by behavioral problems and physical defects including malformations of the eye and associated optical defects. How these malformations affect retinal functioning is not well known, although animal models have suggested that scotopic vision is particularly deficient. Age is also known to affect scotopic vision. Here, we determined the combined effects of age and fetal alcohol exposure (FAE) on retinal function using full-field electroretinograms (ERGs) in monkeys (Chlorocebus sabaeus)...

AIM: Prenatal exposure to alcohol has adverse ramifications on foetal development resulting in developmental abnormalities and major congenital anomalies. Experimental studies have documented effects on kidney structure and function among offspring exposed to alcohol during foetal life; however, human evidence is scarce. Thus, the present study aimed to determine the development of CKD among a cohort of 30-year-old Australian offspring whose mothers reported consumption of alcohol during pregnancy...

We examined the effect of chronic prenatal alcohol exposure on certain neuronal systems involved with the sleep-wake cycle of C57BL/6J mice exposed to prenatal alcohol once they had reached 56 days post-natal. Pregnant mice were exposed to alcohol, through oral gavage, on gestational days 7-16, with recorded blood alcohol concentration (BAC)s averaging 1.84 mg/ml (chronic alcohol group, CA). Two control groups, an oral gavage sucrose control group (chronic alcohol control group, CAc) and a non-treated control group (NTc), were also examined...

The adverse effects of prenatal nicotine and alcohol exposure on human reproductive outcomes are a major scientific and public health concern. In the United States, substantial percentage of women (20-25%) of childbearing age currently smoke cigarettes and consume alcohol, and only a small percentage of these individuals quit after learning of their pregnancy. However, there are very few scientific reports on the effect of nicotine in prenatal alcohol exposure on the cerebellum of the offspring. Therefore, this study was conducted to investigate the cerebellar neurotoxic effects of nicotine in a rodent model of Fetal Alcohol Spectrum Disorder (FASD)...

Adverse maternal behaviors during pregnancy and unfavorable postnatal experiences during development are associated with an increased risk of developing psychiatric disorders, as well as, a vulnerability to alcohol addiction in adulthood. Here, we examined the effects of combined ethanol exposure during late pregnancy and postnatal maternal separation (MS) on HPA responsiveness, anxiety behavior and preference for alcohol consumption in adult male rats. Animals exposed to both conditions revealed a decrease in blood levels of allopregnanolone accompanied by increased anxiety behavior...

Prenatal methamphetamine exposure has become an increasingly pervasive concern, especially in rural-based populations and populations of lower socioeconomic status. While research has begun to highlight the effects of prenatal methamphetamine exposure, the long-term impact of this exposure remains an under-investigated topic. This study attempts to investigate the neurocognitive and neurodevelopmental effects of prenatal methamphetamine exposure by comparing the index and full-scale IQ scores on the WISC-IV between a sample of clinically referred children prenatally exposed to methamphetamine (N = 80) and a sample of clinically referred nonexposed children diagnosed with ADHD (N = 44)...

Alcohol (ethanol) disturbs cognitive functions including learning and memory in humans, non-human primates, and laboratory animals such as rodents. As studied in animals, cellular mechanisms for learning and memory include bidirectional synaptic plasticity, long-term potentiation (LTP), and long-term depression (LTD), primarily in the hippocampus. Most of the research in the field of alcohol has analyzed the effects of ethanol on LTP; however, with recent advances in the understanding of the physiological role of LTD in learning and memory, some authors have examined the effects of ethanol exposure on this particular signal...

The fetal brain is highly vulnerable to ethanol exposure, which can trigger various long-term neuronal disabilities and cognitive dysfunctions. However, a comprehensive understanding of fetal brain development under ethanol exposure is challenging due to the limitations of animal models. Here, we propose a human induced pluripotent stem cell (hiPSC)-based 3D brain organoid model, and explore the mechanisms underlying neural dysfunctions in prenatal alcohol exposure (PAE) in vitro. Brain organoids were examined to resemble brain organogenesis in vivo at early stages during gestation, with specific features of neuronal differentiation, brain regionalization, and cortical organization...

We examined the effect of chronic prenatal alcohol exposure (PAE) on the process of adult neurogenesis in C57BL/6J mice at early adulthood (PND 56). Pregnant mice, and their in utero litters, were exposed to alcohol, through oral gavage, on gestational days 7-16, with recorded blood alcohol concentrations averaging 184 mg/dL (CA group). Two control groups, sucrose (CAc) and non-treated (NTc) control groups were also examined. The brains of pups at PND 56 from each experimental group were sectioned in a sagittal plane, and stained for Nissl substance with cresyl violet, and immunostained for Ki-67 which labels proliferative cells and doublecortin (DCX) for immature neurons...

BACKGROUND: Many children in the remote Fitzroy Valley region of Western Australia have prenatal alcohol exposure (PAE). Individuals with PAE can have neurodevelopmental impairments and be diagnosed with one of several types of Fetal Alcohol Spectrum Disorder (FASD). Fine motor skills can be impaired by PAE, but no studies have developed a comprehensive profile of fine motor skills in a population-based cohort of children with FASD. We aimed to develop a comprehensive profile of fine motor skills in a cohort of Western Australian children; determine whether these differed in children with PAE or FASD; and establish the prevalence of impairment...
