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)...

INTRODUCTION: Excessive alcohol use is associated with car crashes, violence, and multiple disease conditions, including fetal alcohol spectrum disorders. The U.S. Preventive Services Task Force (USPSTF) recommends that primary care providers screen all adults and conduct brief counseling interventions with those who misuse alcohol. The USPSTF prefers use of three screening tools that measure alcohol consumption (Alcohol Use Disorders Identification Test, Alcohol Use Disorders Identification Test-Consumption, and National Institute on Alcohol Abuse and Alcoholism Single Question) because these tools detect the full spectrum of alcohol misuse in adults...

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)...

We present a Riemannian framework for linear and quadratic discriminant classification on the tangent plane of the shape space of curves. The shape space is infinite dimensional and is constructed out of square root velocity functions of curves. We introduce the notion of mean and covariance of shape-valued random variables and samples from a tangent space to the pre-shapes (invariant to translation and scaling) and then extend it to the full shape space (rotational invariance). The shape observations from the population are approximated by coefficients of a Fourier basis of the tangent space...

Drinking mothers expose their fetuses to ethanol, which produces birth defects: craniofacial defects, cognitive impairment, sensorimotor disabilities and organ deformities, collectively termed as fetal alcohol spectrum disorder (FASD). Various congenital heart defects (CHDs) are present in FASD patients, but the mechanisms of alcohol-induced cardiogenesis defects are not completely understood. This study utilized zebrafish embryos and older larvae to understand FASD-associated CHDs. Ethanol-induced cardiac chamber defects initiated during embryonic cardiogenesis persisted in later zebrafish life...

INTRODUCTION:  Being not perceived as risky for health, alcohol consumption is socially accepted worldwide. Nevertheless, related risks for the fetus are relevant, even for occasional use. In Italy there is a high consumption of alcohol among young people and pregnant women, and an increasing number of children born with alcohol-related disorders. AIM: To investigate the knowledge on fetal alcohol-related disorders among students over 18 years of age in a regional capital in the North of Italy...

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...

This article explores medical, midwifery, and nurse practitioner students' attitudes about women who may consume alcohol throughout their pregnancies. Twenty-one health care students responded to a scenario-based vignette addressing alcohol consumption during pregnancy, as well as a semistructured interview, which were analyzed using Braun and Clarke's thematic analysis approach. Two primary themes related to students' attitudes concerning alcohol consumption during pregnancy were identified: (a) divergent recommendations for different women, based on perceptions of their level of education, culture/ethnicity, and ability to stop drinking; and (b) understanding the social determinants of health, including the normalization of women's alcohol consumption and potential partner violence...

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...

Fetal alcohol spectrum disorders (FASD) are caused by ethanol exposure during the pregnancy and is the leading cause of mental retardation. Ethanol exposure during the development results in the loss of neurons in the developing brain, which may underlie many neurobehavioral deficits associated with FASD. It is important to understand the mechanisms underlying ethanol-induced neuronal loss and develop appropriate therapeutic strategies. One of the potential mechanisms involves neuroimmune activation. Using a third trimester equivalent mouse model of ethanol exposure, we demonstrated that ethanol induced a wide-spread neuroapoptosis, microglial activation, and neuroinflammation in C57BL/6 mice...

Fetal alcohol spectrum disorder is associated with defects in neuronal generation, migration, and differentiation. The present study tested the hypothesis that ethanol exposure during the period of naturally occurring neuronal death causes a time- and Bax-dependent neuronal loss. Wild-type and Bax knockout mice were given a pair of injections (two hours apart) of ethanol (2.5 g/kg) or saline on postnatal day (P) 4, P7, P10, or P13. Mean blood ethanol concentration was 435 mg/dl one hour after the second injection...

Background: Neonatal body composition likely mediates fetal influences on life long chronic disease risk. A better understanding of how maternal lifestyle is related to newborn body composition could thus inform intervention efforts. Methods: Using Cork participant data (n = 1754) from the Screening for Pregnancy Endpoints (SCOPE) cohort study [ECM5(10)05/02/08], we estimated how pre-pregnancy body size, gestational weight gain, exercise, alcohol, smoking and diet were related to neonatal fat and fat-free mass, as well as length and gestational age at birth, using quantile regression...

The fetal brain exhibits exquisite alcohol-induced regional neuronal vulnerability. A candidate mechanism for alcohol-mediated brain deficits is disruption of amino acid (AA) bioavailability. AAs are vitally important for proper neurodevelopment, as they comprise the most abundant neurotransmitters in the brain and act as neurotransmitter precursors, nitric oxide donors, antioxidants, and neurotrophic factors, which induce synaptogenesis, neuronal proliferation, and migration. We hypothesized that gestational alcohol alters brain AA concentrations, disrupts AAs associated with neuropathogenesis, and that alterations are region-specific...

OBJECTIVE: Recently, increased attention has been focused on the diagnosis of the most prevalent category of fetal alcohol spectrum disorders, alcohol-related neurodevelopmental disorders (ARNDs). In 2013, proposed criteria for neurodevelopmental disorders associated with prenatal alcohol exposure (ND-PAE) were included in the appendix of the latest revision of the Diagnostic and Statistical Manual of Mental Disorders. The concordance of the 2 sets of criteria is unknown. This study examines the overlap in diagnostic criteria for ND-PAE and the ARND Behavioral Checklist in children...
