Abstract
Reciprocal communication between the gut microbiota and the brain, commonly referred to as the "gut-brain-axis" is crucial in maintaining overall physiological homeostasis. Gut microbiota development and brain maturation (neuronal connectivity and plasticity) appear to be synchronized and to follow the same timeline during childhood (immature), adolescence (expansion) and adulthood (completion). It is important to note that the mesolimbic reward circuitry develops early on, whereas the maturation of the inhibitory frontal cortical neurons is delayed. This imbalance can lead to increased acquirement of reward-seeking and risk-taking behaviors during adolescence, and consequently eventuate in heightened risk for substance abuse. Thus, there is high initiation of alcohol drinking in early adolescence that significantly increases the risk of alcohol use disorder (AUD) in adulthood. The underlying causes for heightened AUD risk are not well understood. It is suggested that alcohol-associated gut microbiota impairment during adolescence plays a key role in AUD neurodevelopment in adulthood. Furthermore, alcohol-induced dysregulation of microglia, either directly or indirectly through interaction with gut microbiota, may be a critical neuroinflammatory pathway leading to neurodevelopmental impairments and AUD. In this review article, we highlight the influence of adolescent alcohol drinking on gut microbiota, gut-brain axis and microglia, and eventual manifestation of AUD. Furthermore, novel therapeutic interventions via gut microbiota manipulations are discussed briefly.

Prenatal ethanol exposure causes anxiety-like phenotype and alters synaptic nitric oxide and endocannabinoid signaling in dorsal raphe nucleus of adult male rats. Transl Psychiatry 2022; 12:440. [PMID: 36216807 PMCID: PMC9550821 DOI: 10.1038/s41398-022-02210-7] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Revised: 09/21/2022] [Accepted: 09/27/2022] [Indexed: 11/08/2022] Open
Abstract
Mood disorders, including anxiety and depression caused by prenatal ethanol exposure (PE) are prevalent conditions in fetal alcohol spectrum disorders (FASDs). Prenatal ethanol exposure is associated with persistent dysfunctions of several neurotransmitter systems, including the serotonin (5-HT) system, which plays a major role in mood regulation and stress homeostasis. While PE is known to disrupt the development of the 5-HT system, the cellular mechanisms by which it alters the function of dorsal raphe nucleus (DRn) 5-HT neurons and their synaptic inputs remain unknown. Here, we used a second-trimester binge-drinking pattern PE (two daily gavages of 15% w/v ethanol at 3 g/kg, 5-6 h apart) during gestational days 8 - 20 and measured anxiety-like behaviors of adult male rats using the elevated plus (EPM) and zero (ZM) mazes. We also employed ex-vivo electrophysiological and pharmacological approaches to unravel the mechanisms by which PE alters the excitability and synaptic transmission onto DRn 5-HT neurons. We found that PE enhanced anxiety-like behaviors in adult male rats and induced a persistent activation of DRn 5-HT neurons. The PE-induced activation of DRn 5-HT neurons was largely mediated by potentiation of DRn glutamate synapses, which was caused by activation of the nitrergic system and impaired endocannabinoid signaling. As such, the present study reveals "push-pull" effects of PE on nitrergic and eCB signaling, respectively, which mediate the enhanced activity of DRn 5-HT neurons and could contribute to anxiety-like behaviors observed in animal model of FASD.

Abstract
Over the past 2 decades, more women in the United States are engaging in excessive alcohol use, including women of reproductive age. Consuming alcohol in amounts greater than recommended limits is associated with an increased risk for adverse health effects, such as breast cancer, hypertension stroke, spontaneous abortion, and infertility. No safe time, safe amount, or safe type of alcohol to consume during pregnancy has been identified. Contradictory beliefs about alcohol use, fear of stigmatization, and potential legal consequences can provide challenges for health care providers who communicate these risks to clients. Health care providers can help to prevent alcohol-related health issues, including alcohol-exposed pregnancies, by providing their clients with factual information about alcohol and health and client-centered options for reducing their health risks. Clinicians can use alcohol screening and brief intervention as a framework for applying the ethical principles of autonomy, veracity, beneficence, and nonmaleficence when talking with women in ways that are nonstigmatizing and supportive to help reduce their health risks and prevent alcohol-exposed pregnancies.

GACETA SANITARIA 2019; 34:449-458. [PMID: 30733046 DOI: 10.1016/j.gaceta.2018.11.008] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/20/2018] [Revised: 11/17/2018] [Accepted: 11/20/2018] [Indexed: 01/17/2023]
Abstract
OBJECTIVE To analyse to what extent pregnant women remembered having received health advice regarding alcohol consumption during pregnancy, what the message they perceived was and whether there is social inequality in this regard. METHOD A cross-sectional descriptive study was performed with a sample of 426 pregnant women (in their 20th week of pregnancy) receiving care in the outpatient clinics of a university hospital in a southern Spanish city (Seville). The data were collected through face-to-face structured interviews carried out by trained health professionals. RESULTS 43% of the interviewed women stated that they had not received any health advice in this regard. Only 43.5% of the sample remembered having received the correct message (not to consume any alcohol at all during pregnancy) from their midwife, 25% from their obstetrician and 20.3% from their general practitioner. The women with a low educational level were those who least declared having received health advice on the issue. CONCLUSION The recommended health advice to avoid alcohol consumption during pregnancy does not effectively reach a large proportion of pregnant women. Developing institutional programmes which help healthcare professionals to carry out effective preventive activities of foetal alcohol spectrum disorder is needed.
