Abstract
Black garlic has a variety of biological activities, but many consumers cannot accept it because of the garlic odor and the bitter taste. In this study, fermentation with yeast Wickerhamomyces anomalus was adopted to improve the flavor of black garlic juice. Although fermentation reduced antioxidant activities, the garlicky odor and bitter taste were weakened. Metabolomic analysis revealed 141 metabolites were significantly differentially regulated. The upregulated metabolites were mainly related to nucleotides, organic acids and their derivatives, while the downregulated metabolites were mainly related to amino acids, lipids and their derivatives. Flavoromics analysis revealed that 137 metabolites were significantly differentially regulated, particularly garlicky and pungent volatiles were significantly downregulated. Correlation analysis indicated that esters are most closely related to nonvolatile metabolites, and lipids degradation was significantly correlated with volatiles. The results indicated that W. anomalus fermentation is an effective strategy to improve the flavor of black garlic juice.

Abstract
OBJECTIVES Although factors associated with alcohol use have been researched at a population level, descriptions of the alcohol and other drug (AOD) treatment-seeking population in New South Wales (NSW), Australia, are limited. This study addresses this gap by analyzing sociodemographic and health characteristics in the NSW AOD treatment-seeking population. METHODS Self-reported Australian Treatment Outcomes Profile data on substance use, health ratings, and sociodemographic factors were acquired from public AOD services (offering services from counseling to ambulatory/inpatient withdrawal management) in 6 administrative health districts from 2016 to 2019 (n = 14,287). Gaussian and multiple logistic regressions were conducted to examine associations between these factors and alcohol consumption quantity. RESULTS Data were analyzed for patients seeking treatment for alcohol consumption specifically (n = 5929; median age, 44 years; 65% male). Valid alcohol consumption data were available for 5460 patients, among whom the mean volume of alcohol consumed was 311 standard drinks (3110 grams of ethanol) over the past 28 days and 15 standard drinks (150 grams of ethanol) per occasion. Higher volumes were consumed by males and those with recent experiences of violence and/or injecting drug use. Caring for children younger than 5 years and having above-median health ratings were associated with lower alcohol consumption. CONCLUSIONS This study contributes to the characterization of the NSW public AOD treatment population and identifies associations between alcohol consumption, sociodemographic factors, and health ratings among people seeking treatment for alcohol consumption. Findings point towards multilevel assessment and comprehensive interventions for people engaging in treatment for alcohol use. Future research should address barriers to treatment.

High levels of alcohol intoxication and strong support for restrictive alcohol policies among music festival visitors. SUBSTANCE ABUSE TREATMENT PREVENTION AND POLICY 2019; 14:15. [PMID: 30987643 PMCID: PMC6466660 DOI: 10.1186/s13011-019-0203-8] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/19/2018] [Accepted: 03/27/2019] [Indexed: 11/10/2022]
Abstract
Background Alcohol intoxication is associated with problems such as violence, injuries, drunk driving and sexual risk-taking, and music festivals are considered a high-risk setting for high levels of alcohol consumption. This study investigates intoxication levels, drinking habits, and opinions on alcohol use and alcohol policies among visitors at one of the largest music festivals in Sweden in 2017. Methods A cross-sectional study assessing alcohol intoxication levels was conducted at a music festival (~ 50,000 attendees). Two research teams collected data at the two festival entrances during two nights, from approximately 6:00 pm to 01:30 am. Blood alcohol concentration (BAC) levels were measured using breath analyzers. A face-to-face questionnaire was used to interview attendees about their alcohol use in the past 12 months using the Alcohol Use Disorder Identification Test-Consumption (AUDIT-C), as well as about their personal opinions on alcohol use and alcohol policies (statement). BAC levels were compared between categories of various factors using Mann-Whitney U test and Kruskal-Wallis test. The distributions of BAC, AUDIT-C and statement category across gender was analyzed using Pearson’s Chi-square tests. Associations of BAC levels with different factors were analyzed using Spearman rank correlation and multinomial logistic regression. Results A total of 1663 attendees were randomly selected and invited to participate, and 1410 consented (63.7% men, 34.9% women, age 16–64 years). The proportion of drinkers was 81%. Among the drinkers, the median BAC level was 0.082%. Thirty-one percent of the participants had a BAC level above 0.10%. Forty-two percent of the participants reported binge drinking monthly, and 20% said that they binge drank weekly. Sixty-three percent of participants reported risky drinking habits. A self-reported risky alcohol habit increased the risk of a high alcohol intoxication level at the festival. Respondents were supportive of restrictive alcohol policies. Men had significantly higher BAC levels, reported more often risky alcohol habits and were less supportive of restrictive alcohol policies than women. Conclusions The results indicate that participants at music festivals in Sweden have high levels of alcohol intoxication and largely support restrictive alcohol policies. Thus, there is both a need and support for the implementation of alcohol prevention strategies at festivals.

Oxytocin Reduces Alcohol Cue-Reactivity in Alcohol-Dependent Rats and Humans. Neuropsychopharmacology 2018; 43:1235-1246. [PMID: 29090683 PMCID: PMC5916348 DOI: 10.1038/npp.2017.257] [Citation(s) in RCA: 84] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2017] [Revised: 10/08/2017] [Accepted: 10/24/2017] [Indexed: 12/25/2022]
Abstract
Approved pharmacological treatments for alcohol use disorder are limited in their effectiveness, and new drugs that can easily be translated into the clinic are warranted. One of those candidates is oxytocin because of its interaction with several alcohol-induced effects. Alcohol-dependent rats as well as post-mortem brains of human alcoholics and controls were analyzed for the expression of the oxytocin system by qRT-PCR, in situ hybridization, receptor autoradiography ([125I]OVTA binding), and immunohistochemistry. Alcohol self-administration and cue-induced reinstatement behavior was measured after intracerebroventricular injection of 10 nM oxytocin in dependent rats. Here we show a pronounced upregulation of oxytocin receptors in brain tissues of alcohol-dependent rats and deceased alcoholics, primarily in frontal and striatal areas. This upregulation stems most likely from reduced oxytocin expression in hypothalamic nuclei. Pharmacological validation showed that oxytocin reduced cue-induced reinstatement response in dependent rats-an effect that was not observed in non-dependent rats. Finally, a clinical pilot study (German clinical trial number DRKS00009253) using functional magnetic resonance imaging in heavy social male drinkers showed that intranasal oxytocin (24 IU) decreased neural cue-reactivity in brain networks similar to those detected in dependent rats and humans with increased oxytocin receptor expression. These studies suggest that oxytocin might be used as an anticraving medication and thus may positively affect treatment outcomes in alcoholics.

Abstract
The dramatic increase in opioid misuse, opioid use disorder (OUD), and opioid-related overdose deaths in the United States has led to public outcry, policy statements, and funding initiatives. Meanwhile, alcohol misuse and alcohol use disorder (AUD) are a highly prevalent public health problem associated with considerable individual and societal costs. This study provides a critical review of alcohol and opioid misuse, including issues of prevalence, morbidity, and societal costs. We also review research on interactions between alcohol and opioid use, the influence of opioids and alcohol on AUD and OUD treatment outcomes, respectively, the role of pain in the co-use of alcohol and opioids, and treatment of comorbid OUD and AUD. Heavy drinking, opioid misuse, and chronic pain individually represent significant public health problems. Few studies have examined co-use of alcohol and opioids, but available data suggest that co-use is common and likely contributes to opioid overdose-related morbidity and mortality. Co-use of opioids and alcohol is related to worse outcomes in treatment for either substance. Finally, chronic pain frequently co-occurs with use (and co-use) of alcohol and opioids. Opioid use and alcohol use are also likely to complicate the treatment of chronic pain. Research on the interactions between alcohol and opioids, as well as treatment of the comorbid disorders is lacking. Currently, most alcohol research excludes patients with OUD and there is lack of measurement in both AUD and OUD research in relation to pain-related functioning. Research in those with chronic pain often assesses opioid use, but rarely assesses alcohol use or AUD. New research to examine the nexus of alcohol, opioids, and pain, as well as their treatment, is critically needed.

Abstract
BACKGROUND Alcohol use disorders (AUDs) are more prevalent among people who are homeless than in the general population. Thus, homeless individuals experience disproportionately high levels of alcohol-related problems and associated publicly funded criminal justice and healthcare system utilization. Available treatment services, however, are not effective at engaging and treating this population. To better tailor treatment services to their needs, it is imperative we understand this population's perceptions of their alcohol use. OBJECTIVES The aim of this study was to provide description and relative rankings of the advantages and disadvantages of alcohol use from this population's perspectives. METHODS Participants were 44 individuals with lived experiences of AUDs and homelessness who received services at community-based agencies in Seattle, Washington. Open-ended prompts were used in interviews conducted in 2013-2014 to assess the perceived role of alcohol in participants' lives, including participants' perceptions of the advantages and disadvantages of their current drinking, and a conventional content analysis was conducted. RESULTS The most frequently mentioned advantages of drinking included positively and negatively reinforcing psychological reasons, perceived control over drinking, and social benefits. Physical effects, concerns about dependence on alcohol, and health problems were the most commonly mentioned disadvantages. Conclusions/importance: By documenting the perceived advantages and disadvantages of drinking among people with the lived experience of homelessness and AUDs, this study supplies information providers may use to better tailor treatment services to this multimorbid, high service-utilizing population's needs and interests.

Abstract
Alcohol abuse is one of the most important risk factors for health and is a major cause of death and morbidity. Despite this, only about one-tenth of individuals with alcohol abuse disorders receive therapeutic intervention and specific rehabilitation. Among the various dichotomies that limit an effective approach to the problem of alcohol use disorder treatment, one of the most prominent is integrated treatment versus harm reduction. For years, these two divergent strategies have been considered to be opposite poles of different philosophies of intervention. One is bound to the search for methods that aim to lead the subject to complete abstinence; the other prioritizes a progressive decline in substance use, with maximum reduction in the damage that is correlated with curtailing that use. Reduction of alcohol intake does not require any particular setting, but does require close collaboration between the general practitioner, specialized services for addiction, alcohology services and psychiatry. In patients who reach that target, significant savings in terms of health and social costs can be achieved. Harm reduction is a desirable target, even from an economic point of view. At the present state of neuroscientific knowledge, it is possible to go one step further in the logic that led to the integration of psychosocial and pharmacological approaches, by attempting to remove the shadows of social judgment that, at present, are aiming for a course of treatment that is directed towards absolute abstention.

Abstract
BACKGROUND The present paper describes the results of a rating study performed by a group of European Union (EU) drug experts using the multi-criteria decision analysis model for evaluating drug harms. METHODS Forty drug experts from throughout the EU scored 20 drugs on 16 harm criteria. The expert group also assessed criteria weights that would apply, on average, across the EU. Weighted averages of the scores provided a single, overall weighted harm score (range: 0-100) for each drug. RESULTS Alcohol, heroin and crack emerged as the most harmful drugs (overall weighted harm score 72, 55 and 50, respectively). The remaining drugs had an overall weighted harm score of 38 or less, making them much less harmful than alcohol. The overall weighted harm scores of the EU experts correlated well with those previously given by the UK panel. CONCLUSION The outcome of this study shows that the previous national rankings based on the relative harms of different drugs are endorsed throughout the EU. The results indicates that EU and national drug policy measures should focus on drugs with the highest overall harm, including alcohol and tobacco, whereas drugs such as cannabis and ecstasy should be given lower priority including a lower legal classification.

Abstract
Economic crises are complex events that affect behavioral patterns (including alcohol consumption) via opposing mechanisms. With this realist systematic review, we aimed to investigate evidence from studies of previous or ongoing crises on which mechanisms (How?) play a role among which individuals (Whom?). Such evidence would help understand and predict the potential impact of economic crises on alcohol consumption. Medical, psychological, social, and economic databases were used to search for peer-reviewed qualitative or quantitative empirical evidence (published January 1, 1990-May 1, 2014) linking economic crises or stressors with alcohol consumption and alcohol-related health problems. We included 35 papers, based on defined selection criteria. From these papers, we extracted evidence on mechanism(s), determinant, outcome, country-level context, and individual context. We found 16 studies that reported evidence completely covering two behavioral mechanisms by which economic crises can influence alcohol consumption and alcohol-related health problems. The first mechanism suggests that psychological distress triggered by unemployment and income reductions can increase drinking problems. The second mechanism suggests that due to tighter budget constraints, less money is spent on alcoholic beverages. Across many countries, the psychological distress mechanism was observed mainly in men. The tighter budget constraints mechanism seems to play a role in all population subgroups across all countries. For the other three mechanisms (i.e., deterioration in the social situation, fear of losing one's job, and increased non-working time), empirical evidence was scarce or absent, or had small to moderate coverage. This was also the case for important influential contextual factors described in our initial theoretical framework. This realist systematic review suggests that among men (but not among women), the net impact of economic crises will be an increase in harmful drinking. Such a different net impact between men and women could potentially contribute to growing gender-related health inequalities during a crisis.

Abstract
OBJECTIVE Heavy drinking, often defined as more than five drinks per occasion, is a major public health problem worldwide, yet most individuals who drink heavily never receive treatment. Focusing on those who receive treatment, numerous studies have found that alcohol use following treatment is discontinuous, with periods of abstinence alternating with periods of heavy drinking. In contrast, little is known about changes in alcohol use among the majority of individuals who engage in heavy drinking and never receive treatment. The goal of this study was to examine changes in alcohol consumption (proportion of heavy drinking days) in a sample of non-treatment-seeking heavy drinkers (n = 151). METHOD The current study focused on three quantitative models--latent growth curve, latent growth mixture, and latent Markov models--to examine changes in the frequency of heavy drinking days (i.e., ≥ 5/4 drinks per day for men/women) among a sample of heavy drinkers who did not receive any form of treatment or self-help over a 2-year period. RESULTS Participants significantly reduced their frequency of heavy drinking over a 2-year period, and changes in drinking did not show the discontinuity in trajectories often observed in treatment samples. Alcohol use disorder diagnosis predicted higher initial levels of frequent heavy drinking but did not predict changes in the frequency of heavy drinking over time. CONCLUSIONS Most individuals, with or without an alcohol use disorder, reported significant reductions in heavy drinking frequency over time. These results have important implications for a public health approach to the problem of heavy drinking.

Abstract
Alcohol use is one of the top five causes of disease and disability in almost all countries in Europe, and in the eastern part of Europe it is the number one cause. In the UK, alcohol is now the leading cause of death in men between the ages of 16-54 years, accounting for over 20% of the total. Europeans above 15 years of age in the EU on average consume alcohol at a level which is twice as high as the world average. Alcohol should therefore be a public health priority, but it is not. This paper puts forward a new approach to reduce alcohol use and harms that would have major public health and social impacts. Our approach comprises individual behaviour and policy elements. It is based on the assumption that heavy drinking is key. It is simple, so it would be easy to introduce, and because it lacks stigmatising issues such as the diagnosis of addiction and dependence, it should not be contentious.

Abstract
This review describes and discusses studies related to reduced-risk drinking as an additional treatment option for patients with problematic alcohol use and alcohol dependence. The review provides some empirical support for the following statements: (a) reduced-risk drinking is a viable option for at least some problem and dependent drinkers; (b) abstinence and non-abstinence-based treatments appear to be equally effective; (c) allowing patients to choose their treatment goal increases the success rate. The relatively short follow-up period (1-2 years) of the studies hampers a proper evaluation of the added value of the reduced-risk drinking approach.

Abstract
Harm reduction has been increasingly finding its way into public drug policies and healthcare practices worldwide, with successful intervention measures justifiably focussing on the highest-risk groups, such as injecting drug users. However, there are also other types of drug users in need for harm reduction, even though they pose less, low, or no public health risk. Occasionally, drug users may autonomously organise themselves into groups to provide advocacy, harm reduction, and peer-help services, sometimes online. The http://www.daath.hu website has been operated since 2001 by the “Hungarian Psychedelic Community”, an unorganised drug user group with a special interest in hallucinogenic and related substances. As of today, the website serves about 1200 visitors daily, and the online community comprises of more than 8000 registered members. The Daath community is driven by a strong commitment to the policy of harm reduction in the form of various peer-help activities that aim to expand harm reduction without promoting drug use. Our review comprehensively summarises Daath’s user-led harm reduction services and activities from the last ten years, firstly outlining the history and growth phases of Daath, along with its self-set guidelines and policies. Online services (such as a discussion board, and an Ecstasy pill database) and offline activities (such as Ecstasy pill field testing, and a documentary film about psychedelics) are described. In order to extend its harm reduction services and activities in the future, Daath has several social, commercial, and legislative challenges to face. Starting with a need to realign its focus, outlooks for the upcoming operation of Daath are pondered. Future trends in harm reduction, such as separating harm-decreasing from benefit-increasing, are also discussed. We aim to share these innovative harm reduction measures and good practices in order to be critically assessed, and – if found useful – adapted and applied elsewhere.
