BACKGROUNDBinge drinking (BD) among adolescents is a public health concern worldwide. This study assessed the cost-effectiveness and cost-utility of a web-based computer-tailored intervention to prevent BD in adolescence.METHODSThe sample was drawn from a study evaluating the Alerta Alcohol program. The population consisted of adolescents 15 to 19 years of age. Data were recorded at baseline (January to February 2016) and after 4 months (May to June 2017) and were used to estimate costs and health outcomes, as measured by the number of BD occasions and quality-adjusted life years (QALYs). Incremental cost-effectiveness and cost-utility ratios were calculated from National Health Service (NHS) and societal perspectives and for a time horizon of 4 months. A multivariate deterministic sensitivity analysis of best/worst scenarios by subgroups was used to account for uncertainty.RESULTSThe cost of reducing BD occasions by one per month was €16.63 from the NHS perspective, which from the societal perspective resulted in savings of €7986.37. From the societal perspective, the intervention resulted in an incremental cost of €71.05 per QALY gained from the NHS perspective and this was dominant, resulting in savings of €34,126.64 per QALY gained in comparison with the control group. Subgroup analyses showed that the intervention was dominant for girls from both the perspectives and for individuals 17 years or older from the NHS perspective.CONCLUSIONSComputer-tailored feedback is a cost-effective way to reduce BD and increase QALYs among adolescents. However, long-term follow-up is needed to evaluate more fully changes in both BD and health-related quality of life.
背景:青少年酗酒(BD)是一个世界性的公共卫生问题。本研究评估了基于网络的计算机定制干预预防青少年双相障碍的成本效益和成本效用。方法样本取自一项评估Alerta酒精项目的研究。人口由15至19岁的青少年组成。在基线(2016年1月至2月)和4个月后(2017年5月至6月)记录数据,并通过BD次数和质量调整生命年(QALYs)来评估成本和健康结果。从国民保健服务(NHS)和社会角度计算增量成本效益和成本效用比,时间跨度为4个月。通过亚组对最佳/最差情景进行多变量确定性敏感性分析来解释不确定性。结果从NHS的角度来看,每月减少一次BD的成本为16.63欧元,从社会的角度来看,节省了7986.37欧元。从社会的角度来看,从NHS的角度来看,干预导致每个QALY增加71.05欧元的成本,这是主要的,与对照组相比,每个QALY节省了34,126.64欧元。亚组分析表明,从两个角度来看,干预对女孩和从NHS角度来看,对17岁或以上的个人都是主要的。结论计算机个性化反馈是降低青少年双相障碍、提高青少年质量的有效方法。然而,需要长期随访来更全面地评估双相障碍和健康相关生活质量的变化。

Prenatal alcohol exposure (PAE) is increasingly recognized as being associated with a wide range of physical health problems, in addition to the well-defined neurocognitive difficulties that have been reported (Mattson et al., 2019). In line with other prenatal perturbations, including smoking, inadequate nutrition and exposure to stress, exposure of the fetus to alcohol during critical stages of development may contribute to 'developmental origins of health and disease' (DOHaD), as first proposed by Barker and colleagues (1995). DOHaD suggests that a suboptimal environment in early development may increase susceptibility to conditions such as hypertension, insulin resistance and obesity, which are risk factors for prevalent non-communicable chronic diseases such as cardiovascular disease and type II diabetes (Hanson and Gluckman, 2011).

产前酒精暴露(PAE)越来越被认为与广泛的身体健康问题有关,除了已报道的定义明确的神经认知困难(Mattson等人,2019)。正如Barker及其同事首次提出的那样(1995年),与其他产前扰动(包括吸烟、营养不足和压力暴露)一样,胎儿在发育的关键阶段接触酒精可能导致"健康和疾病的发育起源" (DOHaD)。DOHaD表明,早期发育的次优环境可能会增加对高血压、胰岛素抵抗和肥胖等疾病的易感性,这些疾病是心血管疾病和II型糖尿病等普遍非传染性慢性疾病的风险因素(Hanson和Gluckman, 2011)。这篇文章受版权保护。版权所有。

BACKGROUNDDespite severe structural brain abnormalities within the fronto-cerebellar circuit (FCC), cerebellar metabolism studied with FDG-PET is relatively preserved in patients with alcohol use disorder (AUD). The compensatory role of the cerebellum has been explored mainly through fMRI examination of AUD patients with preserved level of performance. The present study aims at examining cerebellar metabolism and its relationship with regional brain metabolism and neuropsychological functioning in AUD patients.METHODSThirty-two recently detoxified AUD patients and 23 controls underwent an FDG-PET examination at rest. Participants also performed a neuropsychological battery assessing executive functions, verbal memory and ataxia.RESULTSCompared to controls, AUD patients had higher glucose-uptake in the cerebellar lobules VIII, in association with hypometabolism notably in several nodes of the FCC. Cerebellar hypermetabolism correlated negatively with regional hypometabolism in the premotor and frontal cortices. This pattern of regional hypermetabolism and hypometabolism related to ataxia and working memory deficits.CONCLUSIONSThese specific brain-behaviour relationships do not fulfil the criteria for brain compensatory processes. Cerebellar hypermetabolism may rather reflect the involvement of different pathological mechanisms, leading to a maladaptive plasticity phenomenon within the FCC in AUD patients who are early in abstinence. Further studies are required to examine the contributions of structural and functional connectivity alterations in the cerebellar hypermetabolism and the changes of these pathological mechanisms with abstinence or relapse.

尽管在额小脑回路(FCC)中存在严重的脑结构异常,但FDG-PET研究的小脑代谢在酒精使用障碍(AUD)患者中相对保留。小脑的代偿作用主要是通过fMRI检查保留表现水平的AUD患者来探索的。本研究旨在探讨AUD患者小脑代谢及其与局部脑代谢和神经心理功能的关系。方法32例新近解毒的AUD患者和23例对照者静息时行FDG-PET检查。参与者还进行了神经心理学测试,评估执行功能、言语记忆和共济失调。结果与对照组相比,AUD患者在小脑小叶VIII中有更高的葡萄糖摄取,与FCC几个节点的低代谢有关。小脑高代谢与运动前皮层和额叶皮层的区域低代谢呈负相关。这种区域高代谢和低代谢模式与共济失调和工作记忆缺陷有关。结论这些特定的脑行为关系不符合脑代偿过程的标准。小脑高代谢更可能反映了不同病理机制的参与,导致早期戒酒的AUD患者FCC内出现适应性可塑性不良现象。需要进一步的研究来检验小脑高代谢的结构和功能连接改变的贡献,以及这些病理机制在戒断或复发时的变化。这篇文章受版权保护。版权所有。

BACKGROUNDHazardous alcohol consumption has significant adverse medical consequences. These effects may be mediated, in part, by alterations in DNA methylation. Thus, DNA methylation signatures in peripheral cells may provide biomarkers of the medical impact of alcohol use and the risk for future alcohol consumption.METHODUsing a high density methylation array, we characterized epigenome-wide DNA methylation in saliva cells with respect to alcohol consumption in a large cohort of male European American veterans. In this study, DNA methylation of over 870,000 CpG DNA sites was profiled in 1,135 European American men. Alcohol consumption was assessed using the Alcohol Use Disorder Identification Test-Consumption (AUDIT-C). Linear regression was applied in an epigenome-wide association study (EWAS), adjusted for confounders. Gene set enrichment analysis was performed in the KEGG database with a correction for gene length.RESULTSWe found that a total of 70 CpG sites reached EWAS-corrected significance (p<6E-08) with small effects on alcohol consumption for individual CpG sites, including 64 new CpG sites and six CpG sites that were previously reported as associated with alcohol use disorder, liver function, body mass index, and lipid metabolism. The most significant CpG site was located in SLC7A11(t=-11.34, p=2.66E-28), a gene involved specifically in cysteine and glutamate transportation. The 70 significant CpG sites were located on 44 genes, including genes involved in amino acid transport and metabolism systems. We identified 68 pathways with a false discovery rate <0.05.CONCLUSIONWe identified novel DNA methylation sites associated with alcohol consumption. Results may shed light on peripheral mechanisms of alcohol consumption on adverse health outcomes among heavy drinkers. This article is protected by copyright. All rights reserved.
危险饮酒具有显著的不良医学后果。这些影响可能部分由DNA甲基化的改变介导。因此,外周细胞中的DNA甲基化特征可能提供酒精使用的医学影响和未来饮酒风险的生物标志物。方法使用高密度甲基化阵列,我们在一大群欧洲裔美国男性退伍军人的唾液细胞中表征了与饮酒有关的表观基因组DNA甲基化。在这项研究中,研究人员分析了1135名欧洲裔美国男性超过87万个CpG DNA位点的DNA甲基化。使用酒精使用障碍识别测试-消费(AUDIT-C)评估酒精消耗。线性回归应用于全表观基因组关联研究(EWAS),调整混杂因素。在KEGG数据库中进行基因集富集分析,并对基因长度进行校正。结果:我们发现共有70个CpG位点达到ewas校正的显著性(p<6E-08),对单个CpG位点的酒精消耗影响较小,包括64个新CpG位点和6个先前报道与酒精使用障碍、肝功能、体重指数和脂质代谢相关的CpG位点。最重要的CpG位点位于SLC7A11(t=-11.34, p=2.66E-28),该基因专门参与半胱氨酸和谷氨酸的运输。70个重要的CpG位点位于44个基因上,包括涉及氨基酸运输和代谢系统的基因。我们确定了68条错误发现率<0.05的通路。结论:我们发现了与饮酒相关的新的DNA甲基化位点。结果可能揭示了酒精消费对重度饮酒者不良健康结果的外围机制。这篇文章受版权保护。版权所有。

BACKGROUNDThe nociceptin/orphanin FQ opioid peptide (NOP) receptor and its endogenous ligand N/OFQ have been implicated in the regulation of drug and alcohol use disorders. In particular, evidence demonstrated that NOP receptor activation blocks reinforcing and motivating effects of alcohol across a range of behavioral measures, including alcohol intake, conditioned place preference and vulnerability to relapse.METHODSHere, we show the effects of pharmacological activation and inhibition of NOP receptors on binge-like alcohol consumption, as measured by the "drinking in the dark" (DID) model in C57BL/6J mice.RESULTSWe found that two potent and selective NOP agonists AT-202 (0, 0.3, 1, 3 mg/kg) and AT-312 (0, 0.3, 1 mg/kg) did not affect binge alcohol drinking at doses that do not affect locomotor activity. AT-202 also failed to alter DID behavior when administered to mice previously exposed to chronic alcohol treatment with an alcohol-containing liquid diet. Conversely, treatment with either the high affinity NOP receptor antagonist SB-612111 (0, 3, 10, 30 mg/kg) or the selective antagonist LY2817412 (0, 3, 10, 30 mg/kg) decreased binge drinking. SB-612111 was effective at all doses examined, LY2817412 was effective at 30 mg/kg. Consistently, NOP receptor knockout mice consumed less alcohol compared to wild type. SB-612111 reduced DID and increased sucrose consumption at doses that do not appear to affect locomotor activity. However, the high dose of SB-612111 (30 mg/kg) reduced alcohol intake but failed to inhibit preference in a two-bottle choice DID model that can assess moderate alcohol intake.CONCLUSIONSThe present results suggest that NOP receptor inhibition rather than activation may represent a valuable approach for treatment of alcohol use disorders characterized by excessive alcohol consumption such as binge drinking.

痛觉肽/孤啡肽FQ阿片肽(NOP)受体及其内源性配体N/OFQ参与药物和酒精使用障碍的调节。特别是,有证据表明,NOP受体的激活阻断了酒精在一系列行为测量中的强化和激励作用,包括酒精摄入、条件位置偏好和易复发性。方法通过C57BL/6J小鼠的“黑暗中饮酒”(DID)模型,研究了NOP受体的药理激活和抑制对狂饮样酒精消耗的影响。结果我们发现两种有效的选择性NOP激动剂at -202 (0,0.3, 1,3 mg/kg)和at -312 (0,0.3, 1 mg/kg)在不影响运动活动的剂量下不影响狂饮。AT-202也未能改变小鼠先前暴露于含酒精的液体饮食慢性酒精治疗的DID行为。相反,高亲和力NOP受体拮抗剂SB-612111(0、3、10、30 mg/kg)或选择性拮抗剂LY2817412(0、3、10、30 mg/kg)均可减少狂饮。SB-612111在所有剂量下都有效,LY2817412在30 mg/kg时有效。与野生型相比,NOP受体敲除小鼠一贯消耗更少的酒精。SB-612111在不影响运动活动的剂量下降低DID并增加蔗糖消耗。然而,高剂量SB-612111 (30 mg/kg)减少了酒精摄入量,但在两瓶选择DID模型中未能抑制偏好,该模型可以评估中度酒精摄入量。结论NOP受体抑制而非激活可能是治疗酗酒等酒精使用障碍的一种有价值的方法。这篇文章受版权保护。版权所有。

BACKGROUNDWhen the primary disabilities associated with fetal alcohol spectrum disorders (FASD) are not well supported, individuals are at higher risk for mental health problems and other secondary conditions. The Families on Track intervention was designed to prevent secondary conditions and improve family functioning in children with FASD. Promising results from a pilot study demonstrated positive effects on child and caregiver outcomes immediately following the intervention. The objective of this study was to examine the sustainability of these effects 6-months post-intervention.METHODSThirty children (ages 4 to 8) with prenatal alcohol exposure and their caregivers were enrolled in the original study. Families were randomized to the Families on Track intervention or an active comparison group that provided comprehensive assessment and individualized feedback. The intervention integrated a positive parenting curriculum and a child skills group. Families were assessed at baseline, post-intervention, and 6-month follow up visits. Follow up data were available for 24 families on child and caregiver outcomes. Data were analyzed using effect size calculations and analysis of variance techniques.RESULTSRelative to the comparison group, intervention families showed continued gains in parenting efficacy and maintained prior improvements in FASD knowledge over the follow-up period. Although intervention families reported a decrease in their needs being met over the follow up period, they continued to report their needs being met to greater extent than those in the comparison group. Consistent with post-intervention outcomes, children in both groups exhibited similar decreases in child disruptive behavior 6 months following the intervention. Unfortunately, positive gains seen at post-intervention for child self-esteem and emotion regulation were attenuated at follow-up.CONCLUSIONSThis pilot study yielded promising effects on important areas of caregiver functioning. However, the intervention's impact on child functioning waned over time, suggesting the need for sustained or alternate child intervention.
当与胎儿酒精谱系障碍(FASD)相关的原发性残疾得不到很好的支持时,个体出现精神健康问题和其他继发性疾病的风险更高。家庭跟踪干预旨在预防FASD儿童的继发性疾病并改善家庭功能。一项试点研究的可喜结果表明,干预后立即对儿童和照顾者的结果产生积极影响。本研究的目的是检查干预后6个月这些效果的可持续性。方法30名产前酒精暴露的儿童(4 - 8岁)及其照顾者被纳入原始研究。这些家庭被随机分配到家庭跟踪干预组或提供全面评估和个性化反馈的积极对照组。干预措施包括积极的育儿课程和儿童技能小组。家庭在基线、干预后和6个月随访时进行评估。对24个家庭的儿童和照顾者结局进行了随访数据。使用效应量计算和方差分析技术对数据进行分析。结果与对照组相比,干预家庭的育儿效果持续提高,并在随访期间保持了FASD知识的先前改善。尽管在随访期间,干预家庭报告其需求得到满足的情况有所减少,但与对照组相比,他们继续报告其需求得到了更大程度的满足。与干预后结果一致,两组儿童在干预后6个月表现出相似的儿童破坏性行为减少。不幸的是,干预后对儿童自尊和情绪调节的积极影响在随访中减弱。结论:这项初步研究在护理者功能的重要领域产生了有希望的效果。然而,随着时间的推移,干预对儿童功能的影响逐渐减弱,这表明需要持续或交替的儿童干预。

BACKGROUNDAlcohol use causes significant disruption of intestinal microbial communities, yet exactly how these dysbiotic communities interact with the host is unclear. We sought to understand the role of microbial products associated with alcohol-dysbiosis in mice on intestinal permeability and immune activation in an in-vitro model system.METHODSMicrobiota samples from binge-on-chronic alcohol-fed and pair-fed male and female mice were cultured in Gifu Anaerobic Broth for 24 hours under anaerobic conditions. Live/whole organisms were removed, microbial products were collected, and added to human peripheral blood mononuclear cells (PBMC) or polarized C2BBe1 intestinal epithelial monolayers. Following stimulation, transepithelial electrical resistance (TEER) was measured using a volt/ohm meter and immune activation of PBMC was assessed via flow cytometry.RESULTSMicrobial products from male and female alcohol-fed mice significantly decreased TEER (mean percentage change from baseline alcohol-fed 0.86 Ω/cm2 v. pair-fed 1.10 Ω/cm2 ) compared to microbial products from control mice. Following ex-vivo stimulation immune activation of PBMC was assessed via flow cytometry. We found that microbial products from alcohol-fed mice significantly increased the percentage of CD38+ CD4+ (mean alcohol-fed 17.32%+0.683% SD v. mean pair-fed 14.2%+1.21% SD, P<0.05) and CD8+ (mean alcohol-fed 20.28%+0.88% SD v. mean pair-fed 12.58%+3.59% SD, P<0.05) T-cells.CONCLUSIONSCollectively, these data suggest that microbial products contribute to immune activation and intestinal permeability associated with alcohol dysbiosis. Further, utilization of these ex-vivo microbial product assays will allow us to rapidly assess the impact of microbial products on intestinal permeability and immune activation and to identify probiotic therapies to ameliorate these defects.

饮酒会导致肠道微生物群落的严重破坏,但这些益生菌群落如何与宿主相互作用尚不清楚。我们试图在体外模型系统中了解与小鼠酒精生态失调相关的微生物产物对肠道通透性和免疫激活的作用。方法将慢性酒精暴饮暴食和配对饲养的雌雄小鼠的微生物群样本在岐阜市厌氧肉汤中厌氧培养24小时。活的/完整的生物体被去除,微生物产物被收集,并加入到人外周血单核细胞(PBMC)或极化C2BBe1肠上皮单分子层。刺激后,使用伏特/欧姆计测量经上皮电阻(TEER),并通过流式细胞术评估PBMC的免疫激活。结果与对照组小鼠相比,雄性和雌性酒精喂养小鼠的微生物产物显著降低了TEER(从基线酒精喂养0.86 Ω/cm2到成对喂养1.10 Ω/cm2的平均百分比变化)。体外刺激后,通过流式细胞术评估PBMC的免疫激活。我们发现,酒精喂养小鼠的微生物产物显著提高了CD38+ CD4+(平均酒精喂养17.32%+0.683% SD vs平均配对喂养14.2%+1.21% SD, P<0.05)和CD8+(平均酒精喂养20.28%+0.88% SD vs平均配对喂养12.58%+3.59% SD, P<0.05) t细胞的百分比。综上所述,这些数据表明微生物产物有助于与酒精生态失调相关的免疫激活和肠道通透性。此外,利用这些离体微生物产品检测将使我们能够快速评估微生物产品对肠道通透性和免疫激活的影响,并确定改善这些缺陷的益生菌疗法。这篇文章受版权保护。版权所有。

The liver is a main target of thyroid hormones (TH), which can regulate the expression of multiple genes in this tissue, most notably, those associated with the metabolism and physiology of lipids. Systemic TH status is associated with biochemical parameters dependent on liver function, including cholesterol level. For this reason, the liver is considered a desirable therapeutic target for tissue-specific thyromimetic action. This article is protected by copyright. All rights reserved.

BACKGROUND Specific-sized species of the carbohydrate hyaluronan elicit a variety of cellular responses mediating tissue integrity and repair, as well as regulating inflammatory responses. Orally provided hyaluronan with an average molecular weight of 35kDa (HA35) protects mice from short term ethanol-induced liver injury. This protection was associated with maintenance of the co-localization of zonula occludins-1 (ZO-1) and occludin at tight junctions in the proximal colon. However, it is not known whether HA35 also protects other regions of the intestine or whether protection is due to a direct and/or indirect interaction of HA35 with the intestinal epithelium. METHODS Female C57BL/6J mice were fed an ethanol containing diet or pair-fed control diet (4 days) and treated with or without HA35 via daily gavage during the last 3 days of ethanol feeding. Intestinal morphology and tight junction integrity was assessed. Differentiated Caco-2 cells were transfected or not with scrambled siRNA or siRNA targeting layilin, a hyaluronan receptor. Caco-2 cells were treated with or without HA35 prior to challenge with ethanol. Localization of tight junction proteins, FITC-dextran permeability and transepithelial electrical resistance (TEER) were evaluated. RESULTS While short-term ethanol did not result in any apparent changes in the gross morphology of the intestine, co-localization of ZO-1 and occludin at tight junctions was decreased in proximal and distal colon. HA35 prevented these effects of ethanol. In differentiated Caco-2 cells, ethanol decreased the localization of ZO-1 and occludin at tight junctions and increased permeability of FITC-dextran. At higher concentrations, ethanol also decreased TEER. Pre-treatment with HA35 prevented these changes. When the hyaluronan receptor Layilin was knocked down in Caco-2 cells, HA35 no longer protected cells from ethanol-induced loss of tight junctions. CONCLUSION Taken together, these data indicate that HA35 interacts with Layilin on intestinal epithelial cells and maintains intestinal tight junction integrity during short-term ethanol exposure.

背景:特定大小的碳水化合物透明质酸引起多种细胞反应,介导组织完整性和修复,以及调节炎症反应。口服平均分子量为35 kDa (HA35)的透明质酸对小鼠短期乙醇(EtOH)诱导的肝损伤具有保护作用。这种保护作用与维持近端结肠紧密连接处窄带闭塞-1 (ZO-1)和闭塞蛋白的共定位有关。然而,目前尚不清楚HA35是否也能保护肠道的其他区域,或者这种保护是由于HA35与肠上皮的直接和/或间接的相互作用。方法:雌性C57BL/6J小鼠分别饲喂含EtOH饲粮或配对饲喂对照饲粮(4 d),在EtOH喂养的最后3 d每日灌胃加或不加HA35。评估肠道形态和紧密连接完整性。分化后的Caco-2细胞分别转染或不转染混乱siRNA或靶向透明质酸受体layilin的siRNA。Caco-2细胞在EtOH攻毒前分别用HA35或不加HA35处理。评估了紧密连接蛋白的定位、异硫氰酸荧光素(FITC)-葡聚糖的通透性和经上皮电阻(TEER)。结果:虽然短期EtOH未引起肠道大体形态的明显变化,但近端和远端结肠紧密连接处ZO-1和occludin的共定位减少。HA35阻止了EtOH的这些作用。在分化的Caco-2细胞中,EtOH降低了ZO-1和occludin在紧密连接处的定位,增加了fitc -葡聚糖的通透性。在较高浓度下,EtOH也会降低TEER。HA35预处理可阻止这些变化。当Caco-2细胞中的透明质酸受体layilin被敲低时,HA35不再保护细胞免受etoh诱导的紧密连接丢失。综上所述,这些数据表明,在短期EtOH暴露期间,HA35与肠上皮细胞上的layilin相互作用并维持肠紧密连接的完整性。
