Presently, there is a scarcity of treatments for FASD.<i>Objectives:</i> To analyze current literature, emphasizing evidence derived from preclinical models, that could potentially inform therapeutic interventions for FASD.<i>Methods:</i> A narrative review was conducted focusing on four prospective treatments: nutritional supplements, antioxidants, anti-inflammatory compounds and environmental enrichment. The review also highlights innovative therapeutic strategies applied during early (e.g. folate administration, postnatal days 4-9) or late (e.g. NOX2 inhibitors given after weaning) postnatal stages that resulted in significant improvements in behavioral responses during adolescence (a critical period marked by the emergence of mental health issues in humans).<i>Results:</i> Our findings underscore the value of treatments centered around nutritional supplementation or environmental enrichment, aimed at mitigating oxidative stress and inflammation, implying shared mechanisms in FASD pathogenesis. Moreover, the review spotlights emerging evidence pertaining to the involvement of novel molecular components with potential pharmacological targets (such as NOX2, MCP1/CCR2, PPARJ, and PDE1).<i>Conclusions:</i> Preclinical studies have identified oxidative imbalance and neuroinflammation as relevant pathological mechanisms induced by prenatal ethanol exposure. The relevance of these mechanisms, which exhibit positive feedback loop mechanisms, appear to peak during early development and decreases in adulthood. These findings provide a framework for the future development of therapeutic avenues in the development of specific clinical treatments for FASD.</p>","PeriodicalId":48957,"journal":{"name":"American Journal of Drug and Alcohol Abuse","volume":" ","pages":"1-22"},"PeriodicalIF":2.7,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141635159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, we explore a novel approach utilizing XAS for the detection of prohibited drugs with common X-ray tube source and photon-counting (PC) detector.<i>Method:</i> To achieve automatic, rapid, and accurate detection of drugs.

Current practices fail to effectively treat pain among persons with OUD, a missed opportunity that is worse in minoritized populations and further producing disparities. In this perspective, we discuss how racism-related stress and disparities in addiction treatments may impact the pain experience, diagnosis, treatment, contribute to developing OUD, and perpetuate stigma. This high-level perspective invites clinicians and researchers to reflect on the biopsychosocial burden imposed upon historically minoritized people with pain and OUD. To address such complex issues, multidisciplinary efforts and methodological improvements are required, imbued by antiracist values.
