Antabuse treatment has mostly been applied to alcohol dependent patients although the heavy users of alcohol are responsible for the major parts of alcohol related problems in our societies. The heavy users of alcohol should be identified both by the general practitioners and the hospital doctors...... in any field and the first intervention should be a health interview connected with a biological monitoring of alcohol damages and thereby many patients would be motivated for moderate drinking. If this is not the case, heavy users should be encouraged to a 6 or better a 12 months supervised treatment...... with Antabuse. This treatment has especially been effective in employees with work-related alcohol problems....

Long-term heavy cannabis use can result in memory impairment. Adolescent users may be especially vulnerable to the adverse neurocognitive effects of cannabis. In a cross-sectional and prospective neuropsychological study of 181 adolescents aged 16-20 (mean 18.3 years), we compared performance indices from one of the most widely used measures of learning and memory--the Rey Auditory Verbal Learning Test--between cannabis users (n=52; mean 2.4 years of use, 14 days/month, median abstinence 20.3 h), alcohol users (n=67) and non-user controls (n=62) matched for age, education and premorbid intellectual ability (assessed prospectively), and alcohol consumption for cannabis and alcohol users. Cannabis users performed significantly worse than alcohol users and non-users on all performance indices. They recalled significantly fewer words overall (pmemory performance after controlling for extent of exposure to cannabis. Despite relatively brief exposure, adolescent cannabis users relative to their age-matched counterparts demonstrated similar memory deficits to those reported in adult long-term heavy users. The results indicate that cannabis adversely affects the developing brain and reinforce concerns regarding the impact of early exposure.

The purpose of this research was to examine the associations of parenting style, religiosity, and peer alcohol use with alcohol use and heavy drinking. Structural equation modeling was used to estimate direct and indirect associations among 5,419 adolescents ages 12-14 years from the National Longitudinal Study of Youth 1997. Adolescents whose parents were authoritative were less likely to drink heavily than adolescents who experienced neglectful or indulgent parenting styles. Religiosity was negatively associated with heavy drinking after other relevant variables were controlled for. Authoritative parenting appears to have both direct and indirect negative associations with the risk of heavy drinking among adolescents. Authoritative parenting, where monitoring and support are above average, and religiosity might help deter adolescents from heavy drinking, even when adolescents experience peer environments where alcohol use is common. Authoritarian parenting, although it was not associated with heavy drinking, was positively associated with alcohol use and peer alcohol use, thus placing adolescents at some risk.
Full Text Available Cognitive biases, including implicit memory associations are thought to play an important role in the development of addictive behaviors. The aim of the present study was to investigate implicit affective memory associations in heavy cannabis users. Implicit positive-arousal, sedation, and negative associations towards cannabis were measured with three Single Category Implicit Association Tests (SC-IAT’s and compared between 59 heavy cannabis users and 89 controls. Moreover, we investigated the relationship between these implicit affective associations and explicit expectancies, subjective craving, cannabis use, and cannabis related problems. Results show that heavy cannabis users had stronger implicit positive-arousal associations but weaker implicit negative associations towards cannabis compared to controls. Moreover, heavy cannabis users had stronger sedation but weaker negative explicit expectancies towards cannabis compared to controls. Within heavy cannabis users, more cannabis use was associated with stronger implicit negative associations whereas more cannabis use related problems was associated with stronger explicit negative expectancies, decreasing the overall difference on negative associations between cannabis users and controls. No other associations were observed between implicit associations, explicit expectancies, measures of cannabis use, cannabis use related problems, or subjective craving. These findings indicate that, in contrast to other substances of abuse like alcohol and tobacco, the relationship between implicit associations and cannabis use appears to be weak in heavy cannabis users.
Conclusion: We can conclude that heavy drinking leads to an increase of alcohol-related injuries. This shows a new dimension on the consequences of this public concern already related with a variety of health and social problems. Furthermore, our results allow us to suggest that about half of alcohol-related injuries could be avoided by removing this consumption pattern.

Several ingredients in personal care products (PCPs) have been classified as endocrine disruptors (EDs) and concern has been raised whether use of PCPs can affect human health. We aimed to characterize Norwegian female users of skin care products and compare life style characteristics between heavy users and non-users. This cross-sectional study consisted of 114 202 women (age 41-76 years) participating in the Norwegian Women and Cancer study, a large population-based prospective cohort study. Based on self-reported questionnaire data, we classified the study subjects into five groups according to a calculated percentage of skin area creamed per day. Life-style characteristics were then compared between heavy users (using body lotion twice a day) and non-users. Change in use from 2003 to 2011 was assessed through repeated measurements ( n = 8484). Heavy users of skin care products had a significantly lower BMI, higher level of physical activity, higher income, higher alcohol consumption, fewer children and a shorter total time of breastfeeding than non-users ( p skin care products was, to a moderate extent (weighted kappa 0.52), consistent over time from 2003 to 2011, and as many as 91.5% of the women were classified into the same user group ±1 category in 2003 and 2011. Heavy users of skin care products differ significantly from non-users on BMI, degree of daily physical activity, income, number of children, use of hormonal pharmaceuticals, smoking and alcohol consumption. Use of skin care products is common among women aged 41-76 years in Norway, and the use is consistent over time.

A subset of frequent users of emergency services are those who use the emergency department (ED) for acute alcohol intoxication. This population and their ED encounters have not been previously described. This was a retrospective, observational, cohort study of patients presenting to the ED for acute alcohol intoxication between 2012 and 2016. We collected all data from the electronic medical record. Frequent users for alcohol intoxication were defined as those with greater than 20 visits for acute intoxication without additional medical chief complaints in the previous 12 months. We used descriptive statistics to evaluate characteristics of frequent users for alcohol intoxication, as well as their ED encounters. We identified 32,121 patient encounters. Of those, 325 patients were defined as frequent users for alcohol intoxication, comprising 11,370 of the encounters during the study period. The median maximum number of encounters per person for alcohol intoxication in a one-year period was 47 encounters (range 20 to 169). Frequent users were older (47 years vs. 39 years), and more commonly male (86% vs. 71%). Frequent users for alcohol intoxication had higher rates of medical and psychiatric comorbidities including liver disease, chronic kidney disease, ischemic vascular disease, dementia, chronic obstructive pulmonary disease, history of traumatic brain injury, schizophrenia, and bipolar disorder. In this study, we identified a group of ED frequent users who use the ED for acute alcohol intoxication. This population had higher rates of medical and psychiatric comorbidities compared to non-frequent users.

Worldwide, alcohol is the most commonly used psychoactive substance. However, heterogeneity among alcohol users has been widely recognized. This paper presents a typology of alcohol users based on an implementation of idiographic methodology to examine longitudinal daily and cyclic (weekly) patterns of alcohol use at the individual level. A secondary data analysis was performed on the pre-intervention data from a large randomized control trial. A time series analysis was performed at the individual level, and a dynamic cluster analysis was employed to identify homogenous longitudinal patterns of drinking behavior at the group level. The analysis employed 180 daily observations of alcohol use in a sample of 177 alcohol users. The first order autocorrelations ranged from -.76 to .72, and seventh order autocorrelations ranged from -.27 to .79. Eight distinct profiles of alcohol users were identified, each characterized by a unique configuration of first and seventh autoregressive terms and longitudinal trajectories of alcohol use. External validity of the profiles confirmed the theoretical relevance of different patterns of alcohol use. Significant differences among the eight subtypes were found on gender, marital status, frequency of drug use, lifetime alcohol dependence, family history of alcohol use and the Short Index of Problems. Our findings demonstrate that individuals can have very different temporal patterns of drinking behavior. The daily and cyclic patterns of alcohol use may be important for designing tailored interventions for problem drinkers. Copyright © 2013 Elsevier Ltd. All rights reserved.

Heavy drinking during adolescence is associated with increased reactivity to alcohol related stimuli and to differential neural development. Alcohol cue reactivity has been widely studied among adults with alcohol use disorders, but little is known about the neural substrates of cue reactivity in adolescent drinkers. The current study aimed to identify changes in blood-oxygen level dependent (BOLD) signal during a cue reactivity task pre- and post-monitored abstinence from alcohol. Demographically matched adolescents (16.0-18.9 years, 54% female) with histories of heavy episodic drinking (HD; n=22) and light or non-drinking control teens (CON; n=16) were recruited to participate in a month-long study. All participants completed a functional Magnetic Resonance Imaging (fMRI) scan with an alcohol cue reactivity task and substance use assessments at baseline and after 28 days of monitored abstinence from alcohol and drugs (i.e., urine toxicology testing every 48-72 h). Repeated-measure analysis of variance (ANOVA) examined main effects of group, time, and group×time interactions on BOLD signal response in regions of interest defined by functional differences at baseline. The HD group exhibited greater (pbrain regions, differences in BOLD response were no longer apparent following a month of abstinence, suggesting a decrease in alcohol cue reactivity among adolescent non-dependent heavy drinkers as a consequence of abstaining from alcohol. These results highlight the malleability of adolescent brain function despite no formal intervention targeting cue reactivity. Increased understanding of the neural underpinnings of cue reactivity could have implications for prevention and intervention strategies in adolescent heavy alcohol users.

Glycemic allostasis is the process by which blood glucose stabilization is achieved through the balancing of glucose consumption rate and release into the blood stream under a variety of stressors. This paper reviews findings on the dynamics of glycemic levels during mental activities on fasting in non-alcohol users and alcohol users with different periods of abstinence. Referred articles for this review were searched in the databases of PubMed, Scopus, DOAJ and AJOL. The search was conducted in 2013 between January 20 and July 31. The following keywords were used in the search: alcohol action on glycemia OR brain glucose OR cognitive functions; dynamics of glycemia, dynamics of glycemia during mental activities; dynamics of glycemia on fasting; dynamics of glycemia in non-alcohol users OR alcohol users; glycemic regulation during sobriety. Analysis of the selected articles showed that glycemic allostasis during mental activities on fasting is poorly regulated in alcohol users even after a long duration of sobriety (1-4 weeks after alcohol consumption), compared to non-alcohol users. The major contributor to the maintenance of euglycemia during mental activities after the night's rest (during continuing fast) is gluconeogenesis.

Availability of alcohol has been associated with alcohol consumption in cross-sectional studies. We examined longitudinally whether change in proximity to off-premise (i.e., no consumption on the premises) beer and liquor outlets is associated with heavy alcohol consumption. Distances from 54,778 Finnish Public Sector study participants' homes to the nearest off-premise beer and liquor outlets were calculated using Global Positioning System-coordinates. Between-individual analyses were used to study the effects of distance to the nearest outlet on heavy alcohol use, and within-individual analyses to study the effects of a change in distance on change in heavy use. Mean follow-up time in 2000-2009 was 6.8 (standard deviation 2.0) years. In a between-individual analysis, decrease from ≥500 m to alcohol use in women (odds ratio 1.23, 95% CI 1.05-1.44), but not in men. In a within-individual analysis decrease from 500 m to 0m in log-transformed continuous distance to the nearest beer outlet increased the odds of heavy alcohol consumption in women by 13% (odds ratio 1.13, 95% CI 1.01-1.27). For the corresponding change in distance to liquor outlet the increase was 3% (odds ratio 1.03, 95% CI 0.97-1.09). Change in distance from home to the nearest off-premise alcohol outlet affects the risk of heavy alcohol consumption in women. This evidence supports policies that restrict physical availability of alcohol. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Cannabis exposure, particularly heavy cannabis use, has been associated with neuroanatomical alterations in regions rich with cannabinoid receptors such as the hippocampus in some but not in other (mainly cross-sectional) studies. However, it remains unclear whether continued heavy cannabis use alters hippocampal volume, and whether an earlier age of onset and/or a higher dosage exacerbate these changes. Twenty heavy cannabis users (mean age 21 years, range 18-24 years) and 23 matched non-cannabis using healthy controls were submitted to a comprehensive psychological assessment and magnetic resonance imaging scan at baseline and at follow-up (average of 39 months post-baseline; standard deviation=2.4). Cannabis users started smoking around 16 years and smoked on average five days per week. A novel aspect of the current study is that hippocampal volume estimates were obtained from manual tracing the hippocampus on T1-weighted anatomical magnetic resonance imaging scans, using a previously validated protocol. Compared to controls, cannabis users did not show hippocampal volume alterations at either baseline or follow-up. Hippocampal volumes increased over time in both cannabis users and controls, following similar trajectories of increase. Cannabis dose and age of onset of cannabis use did not affect hippocampal volumes. Continued heavy cannabis use did not affect hippocampal neuroanatomical changes in early adulthood. This contrasts with prior evidence on alterations in this region in samples of older adult cannabis users. In young adults using cannabis at this level, cannabis use may not be heavy enough to affect hippocampal neuroanatomy.

Early age at onset of alcohol use is a risk factor for later heavy alcohol use, but some individuals are buffered from this risk. To better understand this process, this study investigated the interactive contributions of parental coping suggestions, skin conductance level reactivity (SCLR), and age at onset of alcohol use on heavy alcohol use in college students. College students (N = 146, 77% female) reported their age at onset of alcohol use, frequency of recent heavy alcohol use, and their parents' coping suggestions; SCLR was monitored as participants completed a laboratory challenge task. In addition, students' parents (N = 73, 77% mothers) reported on their coping suggestions. Results indicated that in the presence of physiological risk only (blunted SCLR, late age at onset of alcohol use), higher frequencies of engagement and disengagement parental coping suggestions were protective against heavy alcohol use in college students. However, if both risk factors were present (blunted SCLR, early age at onset of alcohol use), more engagement suggestions predicted more heavy alcohol use among college students. These findings extend previous findings on the impact of parenting on heavy alcohol use among college students and provide novel evidence for the moderating role of sympathetic stress reactivity.

Restaurant employees often have high rates of heavy drinking and problems with alcohol. This study evaluates reductions in drinking and associated problems at work, in connection with a new program for prevention and early intervention. The program, called Team Resilience, is designed for young restaurant workers. A cluster-randomized trial design was used, with 28 stores from a national casual-dining restaurant chain and 235 of their employees (54% male, 46% female). Fourteen stores received the Team Resilience training workshop, consisting of three 2-hour sessions held on 3 consecutive days. Sessions included group discussion, role-play and practice activities, and a learning game. Workers in trained stores reported significantly greater decreases in recurring heavy drinking (i.e., having five or more drinks on the same occasion, on 5 or more days in the past month) and work-related problems with alcohol than workers in control stores. In the intervention group, the odds of recurring heavy drinking declined by about one half and the number of work-related problem areas declined by one third following training. In addition, drinking behaviors and problems were tied to age and were most common among employees in their middle 20s. Findings support Team Resilience as an effective intervention for reducing drinking and associated problems among young restaurant workers, a population with substantial needs.

Potential strategies to address alcohol misuse remain contentious. We aim to characterise the drink purchases of one population group: heavy drinkers in contact with Scottish health services. We contrast our findings with national sales data and explore the impact of socio-economic status on purchasing behaviour. Cross-sectional study comparing alcohol purchasing and consumption by heavy drinkers in Edinburgh and Glasgow during 2012. 639 patients with serious health problems linked to alcohol (recruited within NHS hospital clinics (in- and out-patient settings) 345 in Glasgow, 294 in Edinburgh) responded to a questionnaire documenting demographic data and last week's or a 'typical' weekly consumption (type, brand, volume, price, place of purchase). Scottish Index of Multiple Deprivation quintile was derived as proxy of sociodemographic status. Median consumption was 184.8 (IQR = 162.2) UK units/week paying a mean of 39.7 pence per alcohol unit (£0.397). Off-sales accounted for 95% of purchases with 85% of those purchase the majority of their drinks from off-sale settings seeking the cheapest drinks, often favouring local suppliers. While beer was popular, recent legislation impacting on the sale of multibuys may prevent the heaviest drinkers benefiting from the lower beer prices available in supermarkets. Non-etheless, drinkers were able to offset higher unit prices with cheaper drink types and maintain high levels of consumption. Whilst price is key, heavy drinkers are influenced by other factors and adapt their purchasing as necessary. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

Psychiatric epidemiology has revealed a number of associations between gender, socioeconomic status, and psychiatric disorders. To examine psychosocial conditions on and off the job in relation to psychological ill health. Longitudinal design with 24 year follow up of employed persons (190 women, 177 men). Interview and questionnaire data on work and leisure conditions were collected in 1969 and 1993. Risk analyses were performed in relation to three outcomes in 1993: depression within the preceding 12 months, impaired psychological wellbeing, and heavy alcohol use. Thirteen per cent of the women and 11% of the men showed symptoms of depression, 21% and 22% had impaired psychological wellbeing, and 7% and 15% respectively were heavy alcohol users. Dissatisfaction with the quality (women) or quantity (men) of social contacts 24 years earlier was a significant risk factor for depression. Dissatisfaction with the quality of social contacts was also associated with impaired psychological wellbeing (among women), and dissatisfaction with leisure time activities was associated with heavy alcohol use (among men). Frequent overtime work 24 years earlier was associated with heavy alcohol use among women. Cross sectional analyses also showed associations between psychological ill health and some work related factors (mentally demanding work and lack of job pride). Perceived inadequacies in social contacts, and practical obstacles to social relationships are viewed as risk factors for depression. In this longitudinal study, work related factors, including mental demands and time pressure, do not appear sufficiently associated with psychological ill health.
Full Text Available Background: Heavy drinking is responsible for major health and social problems. Slovenia has few epidemiological studies about drinking, none of them have used the AUDIT questionnaire. Pilot studies have indicated that a Webbased screening is likely to be acceptable to young heavy drinkers. Methods: Cross sectional study. Visitors of a free website, older then 10 years, were offered screening with the Alcohol Use Disorder Identification Test (AUDIT. Their demographic data and information about their drinking habits were collected. All users who completed the questionnaire received a specially prepared feed-back message with an evaluation of their drinking. Data from the database for the first four months were collected for analysis on February 1, 2009. Results: In four months 3329 users filled in the questionnaire, 69.2 % completed it and 1790 participans completed it for themselves. Their mean age was 28.9 years, 62.7 % were between 19 and 34 years. 41 % were single, 49.4 % had finnished the secondary school. 0.1 % of men did not drink alcohol at all, 57.7 % drank hazardous or harmful amounts of alcohol. 50.6 % of women did not have risky drinking habits. Mean baseline AUDIT scores were 8.8 ± 1.3, 9.79 ± 2.1 for men and 7.68 ± 4.7 for women. Conclusions: The alcohol screening website was widely used, especially by young people. The percentage of hazardous male drinkers accessing the site was high. The website seems to be an accessible and useful tool for young people and it could contribute to health promotion and constitute an easier alternative to screening for hazardous and harmful drinking.

A family history of alcoholism has been found associated with problematic alcohol use among college students, but less research has examined the effects of family history density of substance use problems in this population. This study examined the prevalence of family history density of substance use problems and its associations with heavy alcohol use, negative alcohol consequences, and alcohol use disorder in a college sample. Based on a secondary analysis of a probability sample, data were analyzed from 606 undergraduate students. Family history density of substance use problems included both first and second degree biological relatives. Heavy alcohol use was the total number of days in which participants drank five/four or more drinks for men/women, negative alcohol consequences were derived from items commonly asked in college student surveys, and an alcohol use disorder was defined as meeting diagnostic criteria for alcohol abuse or dependence. Point prevalence estimated rates of family history density of substance use problems, and negative binomial, ANCOVA, and logistic regression models examined associations between family history density and the alcohol variables while adjusting for sociodemographic variables. Family history density of substance use problems was not significantly associated with total days of heavy alcohol use. Having a second degree, a first degree, or both a first and second degree relative(s) with a substance use problem, however, was significantly associated with experiencing negative alcohol consequences. In addition, having both a first and second degree relative(s) with a substance use problem significantly increased the odds of having an alcohol use disorder. Family history density of substance use problems may play a role in experiencing negative alcohol consequences and in having an alcohol use disorder among undergraduate college students and may be an important risk factor to assess by college health professionals.

A clinical trial demonstrated that a therapeutic workplace could promote alcohol abstinence in homeless, alcohol-dependent adults. This secondary-data analysis examined rates of homelessness and their relation to the therapeutic workplace intervention and alcohol use during the trial. In the trial, homeless, alcohol-dependent adults could work in a therapeutic workplace for 6 months and were randomly assigned to Unpaid Training, Paid Training, or Contingent Paid Training groups. Unpaid Training participants were not paid for working. Paid Training participants were paid for working. Contingent Paid Training participants were paid for working if they provided alcohol-negative breath samples. Rates of homelessness during the study were calculated for each participant and the three groups were compared. Mixed-effects regression models were conducted to examine the relation between alcohol use (i.e., heavy drinking, drinks per drinking day, and days of alcohol abstinence) and homelessness. Unpaid Training, Paid Training, and Contingent Paid Training participants did not differ in the percentage of study days spent homeless (31%, 28%, 17%; respectively; F(2,94)=1.732, p=0.183). However, participants with more heavy drinking days (b=0.350, phomeless. Reducing heavy drinking and alcohol use may help homeless, alcohol-dependent adults transition out of homelessness.

A comprehensive review of cost drivers associated with alcohol abuse, heavy drinking, and alcohol dependence for high-income countries was conducted. The data from 14 identified cost studies were tabulated according to the potential direct and indirect cost drivers. The costs associated with alcohol abuse, alcohol dependence, and heavy drinking were calculated. The weighted average of the total societal cost due to alcohol abuse as percent gross domestic product (GDP)--purchasing power parity (PPP)--was 1.58%. The cost due to heavy drinking and/or alcohol dependence as percent GDP (PPP) was estimated to be 0.96%. On average, the alcohol-attributable indirect cost due to loss of productivity is more than the alcohol-attributable direct cost. Most of the countries seem to incur 1% or more of their GDP (PPP) as alcohol-attributable costs, which is a high toll for a single factor and an enormous burden on public health. The majority of alcohol-attributable costs incurred as a consequence of heavy drinking and/or alcohol dependence. Effective prevention and treatment measures should be implemented to reduce these costs.

The acute consumption of excessive quantities of alcohol causes well-recognized neurophysiological and cognitive alterations. As people reach advanced age, they are more prone to cognitive decline. To date, the interaction of current heavy alcohol (ethanol [EtOH]) consumption and aging remains unclear. This study tested the hypothesis that negative consequences of current heavy alcohol consumption on neurocognitive function are worse with advanced age. Further, we evaluated the relations between lifetime history of alcohol dependence and neurocognitive function METHODS: Sixty-six participants underwent a comprehensive neurocognitive battery. Current heavy EtOH drinkers were classified using National Institute on Alcohol Abuse and Alcoholism criteria (EtOH heavy, n = 21) based on the Timeline follow-back and a structured clinical interview and compared to nondrinkers, and moderate drinkers (EtOH low, n = 45). Of the total population, 53.3% had a lifetime history of alcohol dependence. Neurocognitive data were grouped and analyzed relative to global and domain scores assessing: global cognitive function, attention/executive function, learning, memory, motor function, verbal function, and speed of processing. Heavy current EtOH consumption in older adults was associated with poorer global cognitive function, learning, memory, and motor function (ps alcohol dependence was associated with poorer function in the same neurocognitive domains, in addition to the attention/executive domain, irrespective of age (ps alcohol consumption is associated with significant impairment in a number of neurocognitive domains, history of alcohol dependence, even in the absence of heavy current alcohol use, is associated with lasting negative consequences for neurocognitive function.

This paper uses the widespread variation across states in the timing of adoption of tougher drunk driving laws that set very low legal blood alcohol limits for drivers under age 21--"zero tolerance" (ZT) laws--to provide new evidence on the causal effect of alcohol use on youth suicide. ZT laws reduced heavy episodic drinking by underage men, with…

Rationale Little is known about the smoking topography characteristics of heavy cannabis users. Such measures may be able to predict cannabis use-related outcomes and could be used to validate self-reported measures of cannabis use. Objectives The current study was conducted to measure cannabis smoking topography characteristics during periods of ad libitum use and to correlate topography assessments with measures of self-reported cannabis use, withdrawal and craving during abstinence, and cognitive task performance. Methods Participants (N=20) completed an inpatient study in which they alternated between periods of ad libitum cannabis use and abstinence. Measures of self-reported cannabis use, smoking topography, craving, withdrawal, and sleep measures were collected. Results Participants smoked with greater intensity (e.g., greater volume, longer duration) on initial cigarette puffs with a steady decline on subsequent puffs. Smoking characteristics were significantly correlated with severity of withdrawal, notably sleep quality and architecture, and craving during abstinence, suggesting dose-related effects of cannabis use on these outcomes. Smoking characteristics generally were not significantly associated with cognitive performance. Smoking topography measures were significantly correlated with self-reported measures of cannabis use, indicating validity of these assessments, but topography measures were more sensitive than self-report in predicting cannabis-related outcomes. Conclusions A dose–effect relationship between cannabis consumption and outcomes believed to be clinically important was observed. With additional research, smoking topography assessments may become a useful clinical tool. PMID:21922170

Research shows that alcohol-related stimuli have the propensity to capture attention among individuals motivated to consume alcohol. Research has further demonstrated that impulsive individuals are especially prone to this type of attentional bias. Recently, it is suggested that alcohol cue exposure can also produce a general narrowing of attention consistent with the activation of approach motivational states. Based on previous models of addiction and recent research on the activation of approach motivational states, we predicted that impulsive individuals would demonstrate a constriction of attentional focus in response to alcohol cue exposure. Participants (n = 392) completed a task assessing attentional breadth in response to alcohol and non-alcohol cues, followed by measures of alcohol use and impulsivity. The findings revealed that impulsivity scores predicted narrowing of attentional scope following the presentation of alcohol cues for heavier drinkers but not for light drinkers. These results suggest that impulsive individuals who drink more heavily demonstrate a narrowing of attention in the presence of alcohol-related incentive cues. Implications for how these findings might account for the link between impulsivity and alcohol use and misuse are discussed.

Background The acute consumption of excessive quantities of alcohol causes well-recognized neurophysiological and cognitive alterations. As people reach advanced age, they are more prone to cognitive decline. To date, the interaction of current heavy alcohol (ETOH) consumption and aging remain unclear. The current paper tested the hypothesis that negative consequences of current heavy alcohol consumption on neurocognitive function are worse with advanced age. Further, we evaluated the relations between lifetime history of alcohol dependence and neurocognitive function Methods Sixty-six participants underwent a comprehensive neurocognitive battery. Current heavy ETOH drinkers were classified using NIAAA criteria (ETOH Heavy, n = 21) based on the Timeline follow-back and a structured clinical interview and compared to non-drinkers, and moderate drinkers (ETOH Low, n = 45). Fifty-three-point-three percent of the total population had a lifetime history of alcohol dependence. Neurocognitive data were grouped and analyzed relative to global and domain scores assessing: global cognitive function, attention/executive function, learning, memory, motor function, verbal function, and speed of processing. Results Heavy current ETOH consumption in older adults was associated with poorer global cognitive function, learning, memory, and motor function (p’sfunction in the same neurocognitive domains, in addition to the attention/executive domain, irrespective of age (p’sfunction.

People who use illicit drugs (PWUD) are known to experience high rates of suicidal behavior. While heavy alcohol use has been associated with suicide risk, its impact on the suicidal behavior of PWUD has not been well characterized. Therefore, we examined the relationship between heavy alcohol use and suicidal behavior among PWUD in Vancouver, Canada. Data are derived from two prospective cohort studies of PWUD in Vancouver, Canada, from 2005 to 2013. Participants completed questionnaires that elicited information regarding sociodemographics, drug use patterns, and mental health problems, including suicidal behavior. We used recurrent event survival analyses to estimate the independent association between at-risk/heavy drinking (based on National Institute of Alcohol Abuse and Alcoholism [NIAAA] criteria) and risk of incident, self-reported suicide attempts. Of 1757 participants, 162 participants (9.2%) reported 227 suicide attempts over the 8-year study period, resulting in an incidence rate of 2.5 cases per 100 person-years. After adjusting for potential confounders, including intensive illicit drug use patterns, heavy alcohol use (adjusted hazard ratio [AHR] = 1.97; 95% confidence interval [CI] = 1.39, 2.78) was positively associated with an increased risk of suicidal behavior. We observed a high burden of suicidal behavior among a community-recruited sample of PWUD. Heavy alcohol use predicted a higher risk of suicide attempt, independent of other drug use patterns. These findings demonstrate the need for evidence-based interventions to address suicide risk among PWUD, particularly those who are heavy consumers of alcohol. Copyright © 2015 Elsevier Ireland Ltd.

We examined the hypothesis that family, peer and neighborhood violence would moderate relations between heavy alcohol use and adolescent dating violence perpetration such that relations would be stronger for teens in violent contexts. Random coefficients growth models were used to examine the main and interaction effects of heavy alcohol use and four measures of violence (family violence, friend dating violence, friend peer violence and neighborhood violence) on levels of physical dating violence perpetration across grades 8 through 12. The effects of heavy alcohol use on dating violence tended to diminish over time and were stronger in the spring than in the fall semesters. Consistent with hypotheses, across all grades, relations between heavy alcohol use and dating violence were stronger for teens exposed to higher levels of family violence and friend dating violence. However, neither friend peer violence nor neighborhood violence moderated relations between alcohol use and dating violence. Taken together, findings suggest that as adolescents grow older, individual and contextual moderators may play an increasingly important role in explaining individual differences in relations between alcohol use and dating violence. Implications for the design and evaluation of dating abuse prevention programs are discussed.

Polydrug users have been shown to be at higher risk for alcohol consumption and crash involvement. However, research has shown that polydrug groups differ in some important ways. It is currently unknown how polydrug-using groups differ in terms of crash involvement and alcohol consumption. The current study used latent class analysis to examine subgroups of polydrug users (n = 384) among a sample of drivers in Virginia Beach, Virginia (N = 10,512). A series of logistic regression analyses were conducted to determine the relationship between polydrug use categories and crash involvement and alcohol consumption. Four distinct subclasses of users were identified among polydrug-using drivers: Class 1 is the "marijuana-amphetamines class" and accounts for 21.6% of polydrug users. Class 2 is the "benzo-antidepressant class" and accounts for 39.0% of polydrug users. Class 3 is the "opioid-benzo class" and accounts for 32.7% of polydrug users. Finally, Class 4 is the "marijuana-cocaine class" and accounts for 6.7% of the study sample. Drivers in the opioid-benzo class were significantly more likely than those in any other class as well as non-drug users and single-drug users to be involved in a crash and were more likely than those in most other conditions to consume alcohol. No significant difference was found between marijuana-amphetamine users or benzo-antidepressant users and non-drug users on crash risk. Some polydrug users are indeed at greater risk for crash involvement and alcohol consumption; however, not all polydrug users are significantly worse than single-drug users and/or non-drug users, and the practice of lumping polydrug users together when predicting crash risk runs the risk of inaccurately attributing crash involvement to certain drivers.

Studies have suggested that wine drinkers are at lower risk of death than beer or spirit drinkers. The aim of this study is to examine whether the risk of becoming a heavy drinker or developing alcoholic cirrhosis differs among individuals who prefer different types of alcoholic beverages. In a longitudinal setting we found that both the risk of becoming a heavy or excessive drinker (above 14 and 21 drinks per week for women and above 21 and 35 drinks per week for men) and the risk of developing alcoholic cirrhosis depended on the individuals preference of wine, beer or spirits. We conclude that moderate wine drinkers appear to be at lower risk of becoming heavy and excessive drinkers and that this may add to the explanation of the reported beverage-specific differences in morbidity and mortality.

In 3 previously published works (Brumback et al., 2007, Drug Alcohol Depend 91:10-17; King et al., 2011a, Arch Gen Psychiatry 68:389-399; Roche and King, 2010, Psychopharmacology (Berl) 212:33-44), our group characterized acute alcohol responses in a large group of young, heavy binge drinkers (n = 104) across a variety of subjective, eye-tracking, and psychometric performance measures. The primary goal of the current study was to directly replicate prior findings of alcohol response in heavy social drinkers (HD) in a second independent cohort (n = 104) using identical methodology. A secondary goal was to examine the effects of family history (FH) of alcohol use disorders (AUD) on acute alcohol response in both samples. Participants attended 2 randomized laboratory sessions in which they consumed 0.8 g/kg alcohol or a taste-masked placebo. At pre- and post-drink time points, participants completed subjective scales, psychomotor performance and eye-movement tasks, and provided salivary samples for cortisol determination. Results showed that the second cohort of heavy drinkers exhibited a nearly identical pattern of alcohol responses to the original cohort, including sensitivity to alcohol's stimulating and hedonically rewarding effects during the rising breath alcohol content (BrAC) limb, increases in sedation during the declining BrAC limb, a lack of cortisol response, and psychomotor and eye-tracking impairment that was most evident at peak BrAC. The magnitude and temporal pattern of these acute effects of alcohol in the second cohort were similar to the first cohort across all measures, with the exception of 3 eye-movement measures: pro- and antisaccade accuracy and antisaccade velocity. FH of AUD did not affect alcohol response in the first cohort, and this was replicated in the second cohort. In sum, in 2 independent samples, we have demonstrated that HD display a consistent and reliable sensitivity to alcohol's subjective effects and impairment of eye

There is sparse evidence regarding the effect of alcohol-advertising exposure on alcohol consumption among heavy drinkers. This study aimed to assess the immediate effects of alcohol-promoting and alcohol-warning video advertising on objective alcohol consumption in heavy-drinking young adults, and to examine underlying processes. Between-participants randomized controlled trial with three conditions. Two hundred and four young adults (aged 18-25) who self-reported as heavy drinkers were randomized to view one of three sets of 10 video advertisements that included either (1) alcohol-promoting, (2) alcohol-warning, or (3) non-alcohol advertisements. The primary outcome was the proportion of alcoholic beverages consumed in a sham taste test. Affective responses to advertisements, implicit alcohol approach bias, and alcohol attentional bias were assessed as secondary outcomes and possible mediators. Typical alcohol consumption, Internet use, and television use were measured as covariates. There was no main effect of condition on alcohol consumption. Participants exposed to alcohol-promoting advertisements showed increased positive affect and an increased approach/reduced avoidance bias towards alcohol relative to those exposed to non-alcohol advertisements. There was an indirect effect of exposure to alcohol-warning advertisements on reduced alcohol consumption via negative affect experienced in response to these advertisements. Restricting alcohol-promoting advertising could remove a potential influence on positive alcohol-related emotions and cognitions among heavy-drinking young adults. Producing alcohol-warning advertising that generates negative emotion may be an effective strategy to reduce alcohol consumption. Statement of contribution What is already known on this subject? Exposure to alcohol advertising has immediate and distal effects on alcohol consumption. There is some evidence that effects may be larger in heavy drinkers. Alcohol-warning advertising has

We examined alcohol use disorders, psychiatric symptoms and personality traits in women reporting alcohol use during pregnancy. In a pilot cohort (n=139), subjects were screened for alcohol use disorders, and assessed for psychopathology, personality traits, and alcohol use during the first trimester. Those reporting consumption exceeding a conservative threshold for harmful use were offered a diagnostic psychiatric interview. The main findings of the pilot study were replicated using a large sample of women in the third trimester (n=715), who were screened for alcohol use disorders, had their consumption during pregnancy assessed, and were assessed for personality traits. In the pilot cohort, only a minority of women who consumed significant amounts of alcohol during pregnancy fulfilled alcohol dependence criteria, or had scores on the Alcohol Use Disorder Identification Test typically associated with such a diagnosis. Psychiatric morbidity was also unremarkable as assessed by self-reported symptom intensity. The distinguishing feature was high novelty seeking. The results were robustly confirmed in the replication study. Most women with significant alcohol consumption during pregnancy do not seem to be alcohol dependent. Instead, use during pregnancy may reflect impulsive personality traits, and be correlated with additional risk behaviors.

To examine students' exposure to user-generated alcohol content on social media, and identify characteristics (i.e. demographics, personality traits, alcohol use, alcohol-related cognitions, and social media factors) associated with monthly or more frequent exposure. College/university students (N=11,236) in Bergen, Norway, completed a web-survey measuring exposure to alcohol on social media - both frequency and interpretations of alcohol content. The survey included questions regarding demographics, personality, alcohol-related cognitions, and general use of social media and alcohol. Binary logistic regressions were run to identify characteristics associated with monthly or more frequent exposure to alcohol-related posts on social media. A total of 96.7% had been exposed to alcohol-related posts, exposure to posts with a positive valence of alcohol were more frequently reported than exposure to content with a negative valence of alcohol. Reports of monthly or more frequent exposure to alcohol on social media were associated with a range of characteristics, among these younger age, being native Norwegian, lower extroversion and higher agreeableness and self-monitoring scores, higher alcohol use, stronger descriptive norms for alcohol use among online-friends, and more frequent logins to social media. Students' potential inflated alcohol norms (originating from social media) should be addressed. The results suggest that exposure may be determined by high alcohol use and membership in demographical groups associated with high alcohol use, an increased attentiveness towards others' behavior, and excessive social media use. Future studies investigating the relationship between alcohol exposure on social media and later alcohol use should control for such factors. Copyright © 2017 Elsevier Ltd. All rights reserved.

This article presents findings from a survey of programmes available for tobacco and alcohol users working in 455 of Australia's top 600 companies. Companies were twice as likely to have programmes for smokers (43%) as for problem drinkers (24%) and these programmes were more apparent in large companies. The majority of programmes for smoking were delivered within a health promotion context which included other life-style issues, such as nutrition, exercise, weight management and stress management. Although Employee Assistance Programs (EAPs) were the most commonly available type of work-place programme for excessive drinkers and other drug users, followed by Alcoholics Anonymous and local hospital clinics, only 6% had an EAP for alcohol. Only 21% of programmes for smokers and 12% for excessive alcohol users were evaluated. Around one-quarter of companies knew the costs of smoking programmes, and 9% reported costs of conducting programmes for excessive alcohol consumers.

Heavy alcohol use has been hypothesized to accelerate disease progression to end-stage liver disease in patients with hepatitis C virus (HCV) infection. In this study, we estimated the relative influences of heavy alcohol use and HCV in decompensated chronic liver disease (CLD). Retrospectively, 904 patients with cirrhotic disease admitted to our hospitals during January 2010-December 2012 were identified based on ICD9 codes. A thorough chart review captured information on demographics, viral hepatitis status, alcohol use and progression of liver disease (i.e. decompensation). Decompensation was defined as the presence of ascites due to portal hypertension, bleeding esophageal varices, hepatic encephalopathy or hepatorenal syndrome. Heavy alcohol use was defined as a chart entry of greater than six daily units of alcohol or its equivalent. 347 patients were included based on our selection criteria of documented heavy alcohol use (n = 215; 62.0%), hepatitis titers (HCV: n = 182; 52.5%) and radiological evidence of CLD with or without decompensation (decompensation: n = 225; 64.8%). Independent of HCV infection, heavy alcohol use significantly increased the risk of decompensation (OR = 1.75, 95% CI 1.11-2.75, p < 0.02) relative to no heavy alcohol use. No significance was seen with age, sex, race, HIV, viral hepatitis and moderate alcohol use for risk for decompensation. Additionally, dose-relationship regression analysis revealed that heavy, but not moderate alcohol use, resulted in a three-fold increase (p = 0.013) in the risk of decompensation relative to abstinence. While both heavy alcohol use and HCV infection are associated with risk of developing CLD, our data suggest that heavy, but not moderate, alcohol consumption is associated with a greater risk for hepatic decompensation in patients with cirrhosis than does HCV infection.

Full Text Available Aims: Long-term heavy use of cannabis and alcohol are known to be associated with memory impairments. In this study, we used event-related potentials to examine verbal learning and memory processing in a commonly used behavioral task.Method: We conducted two studies: first, a small pilot study of adolescent males, comprising 13 Drug-Naive Controls (DNC, 12 heavy drinkers (HD and 8 cannabis users (CU. Second, a larger study of young adults, comprising 45 DNC (20 female, 39 HD (16 female, and 20 CU (9 female. In both studies, participants completed a modified verbal learning task (the Rey Auditory Verbal Learning Test, RAVLT while brain electrical activity was recorded. ERPs were calculated for words which were subsequently remembered vs. those which were not remembered, and for presentations of learnt words, previously seen words, and new words in a subsequent recognition test. Pre-planned principal components analyses (PCA were used to quantify the ERP components in these recall and recognition phases separately for each study.Results: Memory performance overall was slightly lower than published norms using the standardized RAVLT delivery, but was generally similar and showed the expected changes over trials. Few differences in performance were observed between groups; a notable exception was markedly poorer delayed recall in HD relative to DNC (Study 2. PCA identified components expected from prior research using other memory tasks. At encoding, there were no between-group differences in the usual P2 recall effect (larger for recalled than not-recalled words. However, alcohol-related differences were observed in a larger P540 (indexing recollection in HD than DNC, and cannabis-related differences were observed in a smaller N340 (indexing familiarity and a lack of previously seen > new words effect for P540 in Study 2.Conclusions: This study is the first examination of ERPs in the RAVLT in healthy control participants, as well as substance

To examine heavy episodic drinking across demographic subgroups to identify where heavy episodic drinking is socially located in an Australian state. Cross-sectional survey, 2483 adult Victorians using Computer Assisted Telephone Interviewing. Two measures of heavy drinking were used: (i) heavy episodic drinking-more than five standard drinks at least weekly; and (ii) typically heavy drinking-50% or more of all drinking occasions involving consumption of 5+ standard drinks. Associations between heavy episodic drinking and eight potential sociodemographic correlates (gender, age, education, income, marital status, ethnic origin, religion and geographical remoteness) were examined. There were few significant correlates of heavy episodic drinking apart from gender and age, once gender and age were controlled. Men were more likely to report heavy episodic drinking than women, but this was attenuated in the measure of typically heavy drinking, suggesting that women reporting heavy episodic drinking were more likely to typically drink that much when they drank. Younger people were more likely to report weekly heavy episodic drinking and more likely to report engaging in this pattern on at least half of their drinking occasions, and this was also true for those unmarried or in de facto relationships. Those of Asian background were less likely to report heavy drinking. In multivariate analysis, the remaining sociodemographic variables were largely unrelated to the drinking measures. The study clearly shows that the prevalence of heavy episodic drinking varies particularly across gender and age groups in Victoria. These variations appear to hold across key sociodemographic variables such as income and education. © 2012 Australasian Professional Society on Alcohol and other Drugs.

Burke and Stephens (1999) [Burke, R.S., Stephens, R.S. Social anxiety and drinking in college students: A social cognitive theory analysis. Clinical Psychology Review, 19, (1999) 513-530.] proposed a social cognitive theory of heavy drinking in college students. According to this theory, alcohol expectancies for social facilitation and self-efficacy for refusing heavy drinking in anxiety-producing social situations moderate the relationship between social anxiety and drinking. In the current study, a significant three-way interaction was observed among social anxiety, expectancies, and self-efficacy when amount and frequency of drinking was the dependent variable. As predicted by the model, socially anxious college students with low self-efficacy for avoiding heavy drinking in social situations and high positive expectancies for social facilitation reported more alcohol consumption than other socially anxious individuals.

Full Text Available Although a few studies have reported that sarcopenia is associated with alcoholic liver disease (ALD, no studies have investigated this association in a large sample representative of the elderly Korean population.This was a cross-sectional study that used data from the Fourth and Fifth Korean National Health and Nutrition Examination Surveys (KNHANES on subjects aged 65 years and older. Sarcopenia was defined as a skeletal muscle index (SMI more than 1 SD below the gender-specific mean for young adults; SMI was calculated as the appendicular muscle mass divided by height squared (ASM/Ht2. Heavy alcohol consumption was defined as consuming at least 210 g/week, and elevated liver enzymes were defined as alanine aminotransferase levels of at least 32 U/L or aspartate aminotransferase levels of at least 34 U/L. ALD was defined as heavy alcohol consumption and elevated liver enzymes.The mean age of the 1,151 elderly males was 71.6 ± 0.2 years, and the prevalence of heavy alcohol consumption was 11.8% (136 subjects. SMI did not differ between the non-heavy and heavy alcohol consumer groups (7.1 ± 0.0 kg/m2 vs. 7.3 ± 0.1 kg/m2, respectively, P = 0.145. However, after stratifying by the presence of liver disease and heavy alcohol consumption and adjusting for other confounders in the multivariate logistic regression, SMI was significantly lower among heavy alcohol consumers with ALD (all P < 0.05. Additionally, two-way ANOVA showed a significant interaction between heavy alcohol consumption and liver disease (P = 0.011.Sarcopenia was accelerated in the elderly male ALD group, with a significant interaction between alcohol consumption and liver disease.

BACKGROUND: Problem alcohol use is common among problem drug users (PDU) and associated with adverse health outcomes. Primary care has an important role in the overall stepped approach to alcohol treatment, especially screening and brief intervention (SBI). AIM: To discuss three themes that emerged from an exploration of the literature on SBI for problem alcohol use in drug users attending primary care. METHODS: Material for this discussion paper was gathered from three biomedical databases (PubMed, PsycINFO and Cochrane library), conference proceedings and online resources of professional organisations or national health agencies. RESULTS: Themes discussed in this paper are: (a) the potential of primary care for delivery of alcohol SBIs to PDUs, (b) screening methods and (c) application of brief interventions to PDUs. CONCLUSIONS: Although SBI improves health outcomes associated with problem alcohol use in the general population, further research is needed among high-risk patient groups, especially PDUs.

A significant proportion of young Australians engage in risky alcohol consumption, and an increasing minority are regular ecstasy (3,4-methylenedioxymethamphetamine) users. Risky alcohol use, alone or in combination with ecstasy, is associated with a range of acute and chronic health risks. The aim of this study was to document the incidence and some health-related correlates of alcohol use, and concurrent alcohol and ecstasy use, among a large, national sample of regular ecstasy users (REU) in Australia. National, cross-sectional surveys of REU in Australia 2003-2008. Among REU in 2008 (n=678) usual alcohol use, psychological distress and health-related quality of life were measured using the Alcohol Use Disorders Identification Test, Kessler Psychological Distress Scale and Short Form-8 Survey respectively. Among REU in 2008, 36% reported high-risk patterns of usual alcohol consumption, 62% reported usually consuming more than five standard drinks with ecstasy, and 24% reported currently experiencing high or very high levels of psychological distress. Controlling for age and education, high-risk drinking among REU was associated with higher levels of psychological distress and poorer health-related functioning; however, the associations between concurrent alcohol and ecstasy use, and health outcomes, were not significant (P>0.05). A large and increasing proportion of REU in Australia engage in high-risk patterns of alcohol consumption, including in combination with ecstasy. High-risk alcohol consumption among this group is associated with adverse health-related outcomes. Prevention and harm reduction interventions for REU should incorporate messages about the risks associated with alcohol use. There is an ongoing need for youth-specific, coordinated alcohol and other drug and mental health services. © 2011 Australasian Professional Society on Alcohol and other Drugs.

To investigate why alcohol consumption varies by marital status, assessing (i) differences in heavy consumption prior to changes in marital status (indicating selection) and increases or decreases in heavy consumption associated with changes in marital status (indicating causation), (ii) whether such increases or decreases are transient, and (iii) the possible mediating effect of parental status. Longitudinal cohort. Great Britain. Data from the 23- and 33-year surveys of the 1958 British birth cohort (all born in England, Wales and Scotland, 3-9 March 1958). Heavy drinking, defined as more than 35 (men) and 20 (women) units/week; changes between ages 23 and 33 in consumption and marital status. The divorced had the highest consumption levels at both ages, the married had the lowest. Selection effects were minimal in both sexes. Overall, heavy drinking declined between ages 23 and 33 (21.4-13.0% in men, 6.4-3.4% in women), but increased among individuals who divorced, compared to the continuously married (adjusted OR = 2.05, 95% CI = 1.49, 2.83 for men; OR = 2.61, 95% CI = 1.67, 4.09 for women), most strikingly for recent divorces (adjusted OR = 4.97, 95% CI = 2.86, 8.57 and OR = 5.25, 95% CI = 2.60, 10.65). High rates of heavy drinking persisted for never married men (19.1%) and women (5.2%). The heavy drinking level of divorced young adults was not due to selection. Marital separation was accompanied by increases in heavy drinking, with pronounced short-term effects. Adverse alcohol-related health consequences may occur in the immediate period around divorce. Individuals who never marry appear to have a chronic heavy consumption pattern that may contribute to their increased mortality.

This study extends previous research on masculinity and negative drinking consequences among young men by considering mediating effects of heavy episodic drinking (HED) and alcohol expectancies. We hypothesized that masculinity would have a direct relationship with negative consequences from drinking as well as indirect relationships mediated by HED and alcohol expectancies of courage, risk, and aggression. A random sample of 1,436 college and university men ages 19-25 years completed an online survey, including conformity to masculine norms, alcohol-related expectancies, HED, and negative drinking consequences. Regression analyses and structural equation modeling were used. Six of seven dimensions of masculinity and the alcohol expectancy scales were significantly associated with both HED and negative consequences. In multivariate regression models predicting HED and negative consequences, the playboy and violence dimensions of masculinity and the risk/aggression alcohol expectancy remained significant. HED and the risk-taking dimension of masculinity were also significant in the model predicting negative consequences. The structural equation model indicated that masculinity was directly associated with HED and negative consequences but also influenced negative consequences indirectly through HED and alcohol expectancies. The findings suggest that, among young adult male college and university students, masculinity is an important factor related to both HED and drinking consequences, with the latter effect partly mediated by HED and alcohol expectancies. Addressing male norms about masculinity may help to reduce HED and negative consequences from drinking.

Full Text Available Background: Very high levels of alcohol consumption have been observed in young adult amphetamine-type stimulant (i.e., ecstasy and methamphetamine users. The reasons for this association are poorly understood. Objective: To examine predictors of hazardous alcohol consumption in a sample of young adult amphetamine-type stimulant users after 30 months of follow-up, controlling for potential confounders. Method: Analysis of longitudinal data from a population-derived sample of Australian young adult amphetamine-type stimulant users (n = 292. A prediction model of alcohol use at 30 months was developed using generalized linear latent and mixed modeling (GLLAMM. Results: Concurrently using ecstasy (Adjusted Odds Ratio [AOR] = 2.67, 95% Confidence Interval [CI] = [1.41, 5.07], frequently attending nightclubs (AOR = 2.53, 95% CI = [1.04, 6.16], high baseline alcohol use patterns (AOR = 2.06, 95% CI = [1.32, 3.20], and being male (AOR = 3.60, 95% CI = [1.48, 8.78] were associated with an increased likelihood of hazardous alcohol use at 30 months. Conclusion: Concurrent, but not baseline, ecstasy use was associated with hazardous alcohol use, suggesting that combined use of these substances may have an instrumental role in terms of the social functions of drug use (e.g., increasing capacity to drink. Integration of educational interventions concerning alcohol and stimulants is warranted.

Recent loosening of state and federal policy restrictions on marijuana, along with changes in social norms regarding marijuana use and decreases in prevalence of other types of substance use, may lead to increases in youth initiating marijuana before other types of substances such as alcohol and tobacco. We investigated predictors and potential consequences of initiating marijuana before other drugs for youth aged 12-21-years in the USA. Nationally representative, cross-sectional survey data from the US National Survey on Drug Use and Health supplied self-reported age of first marijuana, cigarettes, alcohol, other tobacco, and other illegal drug use among 12-21-year-old samples from 2004 to 2014 (n = 275,559). We first examined the degree to which initiating marijuana use first was associated with sex, age, race/ethnicity, and survey year. Then, we examined whether using marijuana first predicted heavy marijuana use, cannabis use disorder (CUD), alcohol use disorder (AUD), nicotine dependence (ND), or lifetime use of other illegal drugs. Among all survey youth (substance users and non-users), the proportion using marijuana first increased from 4.8 to 8.8% from 2004 to 2014. Those using marijuana first (vs. alcohol or cigarettes first) were more likely to be male and older and Black, American Indian/Alaskan Native, multiracial, or Hispanic than White or Asian. Among substance users and adjusting for age of onset and the number of substances used, using marijuana first was associated higher odds of heavy current marijuana use and CUD. In recent years, youth have been increasingly likely to use marijuana as their first drug and sequence of initiation is associated with race/ethnicity, gender, and age. Using marijuana first might increase the chance of heavy use and CUD.

To describe alcohol consumption patterns and risk factors for risky and heavy alcohol use among siblings of childhood cancer survivors compared with survivors and national controls. Secondary analysis of prospectively collected data from two national surveys was performed including a cohort of 3034 adult siblings of childhood cancer survivors (age 18-56 years) and 10,398 adult childhood cancer survivors, both from the Childhood Cancer Survivor Study, plus 5712 adult participants from the population-based National Alcohol Survey. Cancer-related experiences, self-reported current health, and mental health were examined in relation to alcohol consumption patterns including heavy and risky drinking. Adult siblings of childhood cancer survivors were more likely to be heavy drinkers (OR adj = 1.3; 1.0-1.6) and risky drinkers (OR adj = 1.3; 1.1-1.6) compared with controls from a national sample. Siblings were also more likely to drink at these two levels compared with survivors. Factors associated with heavy drinking among siblings included being 18-21 years old (OR adj = 2.9; 2.0-4.4), male (OR adj = 2.3; 1.7-3.0), having a high school education or less (OR adj = 2.4; 1.7-3.5), and drinking initiation at a young age (OR adj = 5.1; 2.5-10.3). Symptoms of depression, (OR adj = 2.1; 1.3-3.2), anxiety (OR adj = 1.9; 1.1-3.3), and global psychiatric distress (OR adj = 2.5; 1.5-4.3) were significantly associated with heavy alcohol use. Siblings of children with cancer are more likely to be risky and heavy drinkers as adults compared with childhood cancer survivors or national controls. Early initiation of drinking and symptoms of psychological distress should be identified during early adolescence and effective sibling-specific interventions should be developed and made available for siblings of children with cancer.

Web-based alcohol interventions are a promising way to reduce alcohol consumption because of their anonymity and the possibility of reaching a high numbers of individuals including heavy drinkers. However, Web-based interventions are often characterized by high rates of attrition. To date, very few studies have investigated whether individuals with higher alcohol consumption show higher attrition rates in Web-based alcohol interventions as compared with individuals with lower alcohol consumption. The aim of this study was to examine the attrition rate and predictors of attrition in a Web-based intervention study on alcohol consumption. The analysis of the predictors of attrition rate was performed on data collected in a Web-based randomized control trial. Data collection took place at the University of Konstanz, Germany. A total of 898 people, which consisted of 46.8% males (420/898) and 53.2% females (478/898) with a mean age of 23.57 years (SD 5.19), initially volunteered to participate in a Web-based intervention study to reduce alcohol consumption. Out of the sample, 86.9% (781/898) were students. Participants were classified as non-completers (439/898, 48.9%) if they did not complete the Web-based intervention. Potential predictors of attrition were self-reported: alcohol consumption in the last seven days, per week, from Monday to Thursday, on weekends, excessive drinking behavior measured with the Alcohol Use Disorder Identification Test (AUDIT), and drinking motives measured by the Drinking Motive Questionnaire (DMQ-R SF). Significant differences between completers and non-completers emerged regarding alcohol consumption in the last seven days (B=-.02, P=.05, 95% CI [0.97-1.00]), on weekends (B=-.05, P=.003, 95% CI [0.92-0.98]), the AUDIT (B=-.06, P=.007, 95% CI [0.90-0.98], and the status as a student (B=.72, P=.001, 95% CI [1.35-3.11]). Most importantly, non-completers had a significantly higher alcohol consumption compared with completers. Hazardous

There is scarce research on male sex workers in the context of alcohol use. While heavy alcohol use has been established as a risk factor for HIV and STI infections among men who have sex with men (MSM), men who engage in sex work with other men, particularly from the Global South, have not been included in these studies. Moreover, studies among male sex workers in Asia often do not explore migration contexts of these men. The objective of this exploratory study is to examine the prevalence and correlates of heavy alcohol use among migrant and non-migrant male sex workers in Bangkok and Pattaya, Central Thailand. Between August and October 2015, 18-24 year-old migrant and non-migrant male sex workers (n = 212) were recruited from various male sex work-identified venues (bars, clubs, massage parlors, and go-go bars) to take an interviewer-administered cross-sectional survey in Bangkok and Pattaya, Thailand. Measures were adapted from previous studies in similar populations and included structured questions across four domains, including demographic characteristics, alcohol use, stimulant use, and sexual behaviors. Multivariable logistic regression assessed the independent associations between heavy alcohol use (heavy versus not heavy) and demographic characteristics, stimulant use and sexual behavior. Heavy alcohol use was prevalent among one-third of participants. Heavy alcohol use was positively associated with male sex workers who were non-migrant and Thai, currently using stimulants, having 15 or more male clients in the past month and having first consumed alcohol at age 15 years or younger. Current HIV prevention efforts should consider subpopulations of MSM, including male sex workers and migrants, as well as other risk behaviors like alcohol, as important contexts for HIV and STI risks.
Full Text Available Studies suggest marijuana impacts gray and white matter neural tissue development, however few prospective studies have determined the relationship between cortical thickness and cannabis use spanning adolescence to young adulthood. This study aimed to understand how heavy marijuana use influences cortical thickness trajectories across adolescence. Subjects were adolescents with heavy marijuana use and concomitant alcohol use (MJ + ALC, n = 30 and controls (CON, n = 38 with limited substance use histories. Participants underwent magnetic resonance imaging and comprehensive substance use assessment at three independent time points. Repeated measures analysis of covariance was used to look at main effects of group, time, and Group × Time interactions on cortical thickness. MJ + ALC showed thicker cortical estimates across the brain (23 regions, particularly in frontal and parietal lobes (ps < .05. More cumulative marijuana use was associated with increased thickness estimates by 3-year follow-up (ps < .05. Heavy marijuana use during adolescence and into young adulthood may be associated with altered neural tissue development and interference with neuromaturation that can have neurobehavioral consequences. Continued follow-up of adolescent marijuana users will help understand ongoing neural changes that are associated with development of problematic use into adulthood, as well as potential for neural recovery with cessation of use.

The objective of this study is to assess the effects of Heavy Episodic Drinking (HED) on the incidence of alcohol-related injuries among university students in Spain, taking sex into consideration. We carried out an open cohort study among college students in Spain (992 women and 371 men). HED and alcohol-related injuries were measured by question 3rd and 9th of Alcohol Use Disorders Identification Test to every participant at the ages of 18, 20, 22, 24 and 27. For data analysis we used a Multilevel Logistic Regression for repeated measures adjusting for alcohol and cannabis use. The incidence rate of alcohol-related injuries was 0.028year -1 for females and 0.036year -1 for males. The multivariate analysis showed that among females a high frequency of HED and use of cannabis are risk factors for alcohol-related injuries (Odds Ratio [OR]=2.64 and OR=3.68), while being more than 23 is a protective factor (OR=0.34). For males, bivariate analysis also showed HED like risk factor (OR=4.69 and OR=2.51). Finally, the population attributable fraction for HED among females was 37.12%. HED leads to an increase of alcohol-related injuries in both sexes and being over 23 years old acts as a protective factor among women. Our results suggest that about one third of alcohol-related injuries among women could be avoided by removing HED. Copyright © 2016 Elsevier Ltd. All rights reserved.

Although major depressive disorder (MDD) and heavy episodic drinking (HED, 4+/5+ drinks in a single sitting for women/men) are common among young adults in college, the relationship between the two remains unclear. This study examined the association between MDD and HED in this population, the effect of gender on this association, and whether comorbid MDD and heavy alcohol use are associated with higher rates of mental health treatment engagement. The study comprised 61,561 (65.3% female) undergraduate students who answered an online survey on depression, alcohol use, and treatment engagement in the past year. Hierarchical linear regressions examined the association between MDD and alcohol use (HED and peak blood alcohol concentration [pBAC]) and whether gender moderated these associations. Logistic regressions were then conducted to examine the influence of MDD, heavy alcohol use, and gender on treatment engagement. Students with MDD reported more frequent HED and higher pBAC than did students without MDD; this was especially true for female students. Rates of treatment engagement were higher among women than men, among students with MDD than students without MDD, and among female students with HED than women without HED. The presence of an association between MDD and heavy alcohol use suggests the need for systematic screenings of both conditions. Low rates of treatment engagement in college students with MDD and heavy alcohol use calls for the development of strategies to engage this high-risk group in treatment.

Heavy alcohol use increases dramatically at age 14, and there is emerging cross-sectional evidence that when girls experience family conflict at younger ages (11-13 years) the risk of alcohol use and misuse is high. This study evaluated the role of family conflict and subsequent depressed mood in predicting heavy alcohol use among adolescent girls. This was a three-wave longitudinal study with annual assessments (modal ages 12, 13, and 14 years). The participants (N = 886, 57% female) were from 12 metropolitan schools in Victoria, Australia, and participants completed questionnaires during school class time. The key measures were based on the Communities That Care Youth Survey and included family conflict (Wave 1), depressed mood (Wave 2), and heavy alcohol use (Wave 3). Control variables included school commitment, number of peers who consumed alcohol, whether parents were living together, and ethnic background. With all controls in the model, depressed mood at Wave 2 was predicted by family conflict at Wave 1. The interaction of family conflict with gender was significant, with girls showing a stronger association of family conflict and depressed mood. Depressed mood at Wave 2 predicted heavy alcohol use at Wave 3. Girls may be especially vulnerable to family conflict, and subsequent depressed mood increases the risk of heavy alcohol use. The results support the need for gender-sensitive family-oriented prevention programs delivered in late childhood and early adolescence.

Alcohol consumption increases health risks and social consequences. It also lowers productivity resulting in economic losses for drinkers and the rest of society. To investigate alcohol drinking behavior and to estimate economic cost incurred by alcohol users in Khon Kaen province in 2007. A cross-sectional survey targeting the population aged 12-65 years old was conducted in 20 communities. Data were collected using full-structured questionnaires through interviews. Among 1,053 respondents, 53.0% drank alcohol sometime in their lives (95% CI: 46.1, 59.9). The percentage of individuals drinking in the past 12 months was 43.3% (95% CI: 37.1, 49.5). The average number of drinking days in past 12 months was 36.8 days. Most respondents drank for social activities, mainly with friends and relatives. Individual costs of alcohol consumption varied greatly. The weighted average cost in 2007 was 975.5 Baht per drinker. The estimated overall cost of alcohol consumption in Khon Kaen, in 2007, was 691.2 million Baht (95% CI: 280.0, 1,102.3 million), or 502.9 Baht per capita. More than half of the Khon Kaen population drank alcohol sometime in their lives and 43.3% were current drinkers. The average number of drinking days in past 12 months was 36.8 days. The estimated cost of alcohol consumption in Khon Kaen province was enormous.

, traditional norms that may directly pertain to hyperfemininzed Asian-American women, including modesty and sexual fidelity, may protect against heavy episodic drinking (Young et al. 2005). Conversely, the risk for heavy episodic drinking may be enhanced in men who strive to demonstrate traditional notions of masculinity through risk-taking and endorsement of playboy norms (Iwamoto et al. 2010). Although this review has illustrated the contemporary state of research on alcohol use among Asian Americans, it also highlights the significant limitations in this literature. Many of the studies reviewed here have used cross-sectional data, which do not allow researchers to infer causality between the various sociocultural factors and problematic alcohol use. One way of addressing this gap in the existing literature may be to implement longitudinal designs to further understand how the temporal relationship between sociocultural factors, including acculturation and gender norms, may impact alcohol use and alcohol-related problem trajectories. There also is a pressing need to develop greater understanding of within-group differences among U.S.-born and foreign-born Asian Americans as well as among as specific ethnic groups. To date, epidemiological research has largely neglected to examine these significant discrepancies. Given the growing prevalence of alcohol use and alcohol-related problems among Asian-American women (Grant et al. 2004; Iwamoto et al. 2010), studies also should focus on this group and explore how the intersection of gender and culture may influence alcohol use. Finally, the majority of research on this population has been conducted in college samples; therefore, it is important to also examine community samples, including U.S.-born young adults who are not attending college and older adult Asian-American populations.

Previous research indicates that users of illicit substances exhibit diminished cognitive function under stereotype threat. Advancing this research, the current study aimed to examine the effects of stereotype threat on alcohol users' inhibitory control. It also examined whether drinkers demonstrate a greater approach bias towards alcohol-related relative to neutral stimuli. Fifty-five participants were assigned randomly to a stereotype threat condition, in which they were primed with a negative stereotype linking drinking behavior to cognitive decline, or a non-threat control condition. All participants then completed a modified version of the Cued Go/No-Go Association Test that exposed participants to alcohol-related and neutral pictorial stimuli and sound cues. Stereotype threatened participants demonstrated a speed-accuracy trade off, taking significantly longer to respond to go-trials with equivalent accuracy to the control condition. They also showed reduced response accuracy to both alcohol-related and neutral stimuli in reversed instruction trials. Participants in the control condition were both more accurate and quicker to respond to alcohol-related stimuli compared to neutral stimuli. These results suggest that awareness of negative stereotypes pertaining to alcohol-related impulsivity may have a harmful effect on inhibitive cognitive performance. This may have implications for public health campaigns and for methodological designs with high levels of procedural signaling with respect to not inadvertently inducing stereotype threat and impacting impulsivity.

This study reports on the views of Primary Health Care (PHC) providers in Southeast Brazil on the use of alcohol and other drugs which reflect stigma, moralization, or negative judgment. Six hundred nine PHC professionals from the Brazilian states of São Paulo and Minas Gerais took part in the study. The majority (86.5%) of these professionals were female. Attitudes toward the use of alcohol and other drugs were evaluated in comparison to Hansen's disease, obesity, depression, schizophrenia, HIV/AIDS, and tobacco use. The use of tobacco, marijuana/cocaine, and alcohol were the most negatively judged behaviors (p health care workers demonstrated the severest judgment of alcohol use. In addition, marijuana/cocaine addicts and alcoholics suffered the highest rate of rejection by professionals. The hypothesis that the use of alcohol and other drugs is a behavior stigmatized by health professionals being confirmed, it is important to develop strategies for changing provider attitudes in order to provide a higher quality of service to these patients. This study is important as a first study among PHC professionals about social stigma of alcohol and other drugs users.

Full Text Available Background: Epidemiological studies suggest that the intracerebral hemorrhage (ICH rate correlates with alcohol consumption. Alcohol leads to elevated blood pressure (BP and inhibition of platelet aggregation. These factors could promote excessive bleeding. To our knowledge, in the setting of normal liver function tests, there are no studies that have systematically evaluated the relationship between daily alcohol use and hematoma expansion. The aim of this study is to compare the baseline ICH characteristics, frequency of hematoma expansion, and outcomes in patients with ICH who are daily alcohol users with those who are not daily alcohol users. Methods: A retrospective chart review was performed on consecutive patients who presented from July 2008 to July 2013 to the Tulane University Hospital in New Orleans, La., USA, with a spontaneous ICH. Ninety-nine patients who met these criteria were admitted. Patients who underwent hematoma evacuation were excluded. Hemorrhage volumes were calculated based on the ABC/2 method. Low-density lipoprotein (LDL was dichotomized into low (2 and nonparametric equivalents where appropriate. ICH growth in 24 h and LDL were evaluated using linear regression. Results: Of the 226 patients who met inclusion criteria, 20.4% had a history of daily alcohol use. The average age was 61 years (range 19-94, 55.6% of the patients were males, and 67.1% were of African American origin. Daily alcohol use was associated with male gender, lower rate of home antihypertensive, higher presenting BP, and lower platelet counts, but there was no difference in ICH characteristics, ICH growth, or clinical outcome. Daily alcohol use in patients with a low LDL level was associated with supratentorial location and trends for lower baseline Glasgow Coma Scale score, higher ICH score, and follow-up ICH volume, but no significant difference in significant hematoma expansion or clinical outcome except for a trend for higher mortality was found

This study was designed to estimate the suicide risk among individuals with illicit drug use alone, illicit drug users with mental disorders, and illicit drug users with alcohol use disorders. Methods Subjects were participants of the 2008 Thai National Mental Health Survey. They were asked for their illicit drug use in the past year. The Mini International Neuropsychiatric Interview (MINI), current suicidality (1 month prior to assessment), mood episodes, anxiety disorders, psychotic disorders, and alcohol use disorders were used for assessing mental/alcohol use disorders.

Results Of the total 17,140 respondents, 537 currently used illicit drugs, while 1,194 respondents had a suicide risk. Common illicit drugs were kratom (59%) and (meth)amphetamine (24%). Compared with 16,603 Thais without illicit drug use, the illicit drug users with or without mental/alcohol use disorders (n=537) had an increased risk of suicide (adjusted odds ratio [OR], 95% confidence interval [CI] =2.09, 1.55–2.81). While those who used illicit drugs alone (no mental/alcohol use disorder) (n=348) had no increased risk of suicide (adjusted OR, 95% CI =1.04, 0.66–1.65), the illicit drug users with mental or alcohol use disorders (n=27 and n=162, respectively) had significantly increased risk of suicide (adjusted ORs, 95% CIs =14.06, 6.50–30.3 and 3.14, 1.98–4.99, respectively). Conclusion A key limitation of this study was the combined suicidal behaviors as a suicidality risk. Mental or alcohol use disorders found in this population actually increased the suicide risk. These findings support the coexisting relationship that mental and alcohol use disorders play a vital role in increasing the suicide

The present experiment assessed motor response programming and movement time in children with histories of heavy prenatal alcohol exposure (PEA). Alcohol-exposed children between the ages of 7 and 17 years were classified into two groups: Fetal Alcohol Syndrome (FAS: n=9) and children with PEA (PEA: n=19) but who did not have the defining characteristics of FAS. The FAS and PEA children were compared with non-alcohol-exposed children (NC: n=23) when completing two tasks: a simple reaction time task (RT alone condition) and a reaction plus movement task (RT+Move condition). The movement involved responding to an imperative stimulus signal and depressing three target buttons in a set sequence. Participants completed 24 trials each for the RT alone and RT+Move response conditions. Results indicated no significant differences in performance among FAS, PEA, and NC groups during the RT alone condition. However, during the RT+Move condition, the FAS group produced significantly longer and more variable RTs than the PEA and NC groups, which produced comparable RTs. The FAS group also produced significantly slower movement times when moving to all three targets, whereas movement time variability did not significantly differ as a function of group.

Chromosomal damage and apoptosis were analyzed in users of mouthwash and/or alcoholic beverages, using the micronucleus test on exfoliated oral mucosa cells. Samples from four groups of 20 individuals each were analyzed: three exposed groups (EG1, EG2 and EG3) and a control group (CG). EG1 comprised mouthwash users; EG2 comprised drinkers, and EG3 users of both mouthwashes and alcoholic beverages. Cell material was collected by gently scraping the insides of the cheeks. Then the cells were fixed in a methanol/acetic acid (3:1) solution and stained and counterstained, respectively, with Schiff reactive and fast green. Endpoints were computed on 2,000 cells in a blind test. Statistical analysis showed that chromosomal damage and apoptosis were significantly higher in individuals of groups EG1 and EG3 than in controls (p < 0.005 and p < 0.001, respectively). No significant difference in chromosomal damage and apoptosis was observed between the exposed groups. In EG2, only the occurrence of apoptosis was significantly higher than in the controls. These results suggest that mouthwashes alone or in association with alcoholic drinks induce genotoxic effects, manifested as chromosomal damage and apoptosis. They also suggest that alcoholic drinks are effective for stimulating the process of apoptosis. However, these data need to be confirmed in larger samples. PMID:25505845

Stress and anxiety are widely considered to be causally related to alcohol craving and consumption, as well as development and maintenance of alcohol use disorder (AUD). However, numerous preclinical and human studies examining effects of stress or anxiety on alcohol use and alcohol-related problems have been equivocal. This study examined relationships between scores on self-report anxiety, anxiety sensitivity, and stress measures and frequency and intensity of recent drinking, alcohol craving during early withdrawal, as well as laboratory measures of alcohol craving and stress reactivity among heavy drinkers with AUD. Media-recruited, heavy drinkers with AUD (N = 87) were assessed for recent alcohol consumption. Anxiety and stress levels were characterized using paper-and-pencil measures, including the Beck Anxiety Inventory (BAI), the Anxiety Sensitivity Index-3 (ASI-3), and the Perceived Stress Scale (PSS). Eligible subjects (N = 30) underwent alcohol abstinence on the Clinical Research Unit; twice daily measures of alcohol craving were collected. On day 4, subjects participated in the Trier Social Stress Test; measures of cortisol and alcohol craving were collected. In multivariate analyses, higher BAI scores were associated with lower drinking frequency and reduced drinks/drinking day; in contrast, higher ASI-3 scores were associated with higher drinking frequency. BAI anxiety symptom and ASI-3 scores also were positively related to Alcohol Use Disorders Identification Test total scores and AUD symptom and problem subscale measures. Higher BAI and ASI-3 scores but not PSS scores were related to greater self-reported alcohol craving during early alcohol abstinence. Finally, BAI scores were positively related to laboratory stress-induced cortisol and alcohol craving. In contrast, the PSS showed no relationship with most measures of alcohol craving or stress reactivity. Overall, clinically oriented measures of anxiety compared with perceived stress were more

Cannabinoids are still classified as illegal psychoactive drugs despite their broad and increasingly acknowledged therapeutic potential. These substances are most famous for their wide recreational use, particularly among young adults to either alter the state of consciousness, intensify pleasure induced by other psychoactive substances or as an alternative to the previously abused drugs. It is important to emphasize that cannabinoids are often taken together with a variety of medications intended for the treatment of alcohol use disorder (AUD) or alcohol withdrawal syndrome (AWS). These medications include disulfiram, acamprosate, and naltrexone. In this paper, we summarize recent advances in the knowledge of possible beneficial effects and interactions between cannabinoids and drugs commonly used for treatment of AUD and AWS either comorbid or existing as a separate disorder.

Full Text Available CONTEXT AND OBJECTIVE: For some patients who have developed significant alcohol-related physical disease, total abstinence from alcohol may offer the best chance of survival. The aim of this study was to investigate motivation for treatment in two groups of alcohol users: outpatients from the gastroenterology clinic and outpatients from the specialist alcohol treatment service. DESIGN AND SETTING: Cross-sectional study, at a federally funded public teaching hospital. METHODS: The sample studied was 151 outpatients from the gastroenterology clinic and 175 from the specialist alcohol treatment service. The interview was conducted in the outpatient clinics at the first appointment, and consisted of demographic questions and scales for measuring quality of life, alcohol dependence, pattern of alcohol, motivation for treatment and consequences of alcohol consumption. RESULTS: The results suggested that outpatients from the gastroenterology clinic were less dependent on alcohol, had suffered fewer consequences from alcohol and had fewer emotional and mental health problems than did the outpatients from the alcohol treatment service. In relation to their stages of change, the gastroenterology outpatients presented high precontemplation scores at the beginning of treatment while outpatients of alcohol treatment service showed higher scores in contemplation, action and maintenance. CONCLUSION: The medical treatment may be a reason for the temporary alcohol abstinence behavior among the gastroenterology outpatients.

Studies suggest marijuana impacts gray and white matter neural tissue development, however few prospective studies have determined the relationship between cortical thickness and cannabis use spanning adolescence to young adulthood. This study aimed to understand how heavy marijuana use influences cortical thickness trajectories across adolescence. Subjects were adolescents with heavy marijuana use and concomitant alcohol use (MJ+ALC, n=30) and controls (CON, n=38) with limited substance use histories. Participants underwent magnetic resonance imaging and comprehensive substance use assessment at three independent time points. Repeated measures analysis of covariance was used to look at main effects of group, time, and Group × Time interactions on cortical thickness. MJ+ALC showed thicker cortical estimates across the brain (23 regions), particularly in frontal and parietal lobes (psadolescence and into young adulthood may be associated with altered neural tissue development and interference with neuromaturation that can have neurobehavioral consequences. Continued follow-up of adolescent marijuana users will help understand ongoing neural changes that are associated with development of problematic use into adulthood, as well as potential for neural recovery with cessation of use.

Worldwide, 16% of people aged 15 and older engage in harmful use of alcohol. Harmful alcohol use leads to a host of preventable negative social and health consequences. Mobile technology-based interventions provide a particularly promising avenue for the widespread and cost-effective delivery of treatment that is accessible, affordable, individualized, and destigmatized to both alcohol-dependent and nondependent individuals. The present review sought to summarize the current literature on mobile technology-based interventions among adult users of alcohol and determine the efficacy of such interventions. Five databases were searched in December 2015 (Jan. 2004-Dec. 2015). Inclusion criteria were: participants aged 18 or older, interventions delivered through mobile-technology, and outcome measurement of alcohol reduction/cessation. Eight studies met inclusion criteria. The majority of the studies reviewed found positive effects of the intervention, even though the interventions themselves varied in design, length, dosage, and target population, and were pilot or preliminary in nature. Findings from this review highlight the promising, yet preliminary state of research in this area. Studies with adequate power and valid design are necessary to evaluate the potential of mobile technology-based interventions on long-term alcohol behavior outcomes. Furthermore, future research should elucidate what the most effective length of time is for a mobile technology-based intervention, how often individuals should receive messages for maximum benefit, and determine the comparative effectiveness of mobile technology interventions with other efficacious interventions.

This article aims to characterize health care models for users of alcohol and other drugs in the Brazilian context. Discourse analysis was performed on public drug policy in Brazil from the 1970s. This analysis was contextualized by a brief digression on the main political positions identified in several countries of the world in relation to drug use problems. Beginning in the current decade, drug policies in Brazil have been receptive to harm reduction approaches, resulting in reorientation of the health care model. In conclusion, the structuring and strengthening of a network of care for users of alcohol and other drugs and their families, based on community care and the harm reduction approach and combined with other social and health services, is now a key public health challenge for the country.

Prior studies have established variation at the PNPLA3gene to be associated with a risk of developing alcoholic liver disease (ALD). We attempt to replicate this finding and other potential genetic variations previously associated with ALD utilizing a case-control design in a cohort of subjects with alcohol use disorders. This case-control study performed in a US clinical sample of heavy drinkers, replicates the previously reported association between ALD and rs738409 polymorphism in the PNPLA3gene in heavy drinkers. This association persisted after accounting for the subject's diabetes status. Patients of European ancestry with a history of ALD were identified (n = 169). Controls consisted of patients without ALD who were from the same cohorts and were ≥ 30 years of age, had lifetime total years drinking ≥20 and lifetime maximum drinks per day ≥12 (n = 259). Patients were genotyped for 40 candidate single nucleotide polymorphisms (SNPs) selected for the purpose of testing their association with ALD. The association of each SNP with ALD was tested using a logistic regression model, assuming log-additive allele effects. Bonferroni correction was applied and multivariable logistic regression models were used to account for relevant covariates. Age, sex, and body mass index (BMI) distributions were similar between cases and controls. Diabetes was more prevalent in the ALD cases. Three SNPs were associated with ALD at the nominal significance level (rs738409 in PNPLA3, P = 0.00029; rs3741559 in AQP2, P = 0.0185; rs4290029 in NVL, P = 0.0192); only PNPLA3rs738409 SNP was significant at the Bonferroni-corrected P-value threshold of 0.00125. Association results remained significant after adjustment for diabetes status. Our case-control study confirmed that PNPLA3 rs738409 SNP is associated with ALD. This is an important replication in a US clinical sample with control subjects who had long histories of alcohol consumption.

Chronic marijuana use has been associated with impairments of learning, memory, and executive functions. Little is known, however, about the effects of marijuana use on other cognitive domains, such as decision-making, which are thought to play an important role in addiction and drug abuse. The purpose of the present study was to determine if long-term heavy marijuana users employ different decision-making strategies than individuals with minimal marijuana exposure. Volunteers were assigned to a cannabis (n = 10) or control group (n = 10) based upon history of prior marijuana use. Demographic and neuropsychological variables were evaluated, and a decision-making task--the gambling task (GT) was administered. Although few demographic and neuropsychological differences were noted between groups, marijuana users made more decisions that led to larger immediate gains despite more costly losses than controls. These data suggest that long-term heavy marijuana users may have specific deficits in the ability to balance rewards and punishments that may contribute to continued drug-taking behavior. It is unknown, however, whether the basis for such deficits might be attributed directly to marijuana exposure or pre-existing genetic or behavioral differences.

Case reports and hospital-based case-control studies suggest that cannabis use may increase the risk of stroke. We examined the risk of non-fatal stroke or transient ischemic attack (TIA) among cannabis users in the general community. A general population survey of Australians aged 20-24 years (n=2,383), 40-44 years (n=2,525) and 60-64 years (n=2,547) was used to determine the odds of lifetime stroke or TIA among participants who had smoked cannabis in the past year while adjusting for other stroke risk factors. There were 153 stroke/TIA cases (2.1%). After adjusting for age cohort, past year cannabis users (n=1,043) had 3.3 times the rate of stroke/TIA (95% CI 1.8-6.3, pcannabis weekly or more often (IRR 4.7, 95% CI 2.1-10.7) with no elevation among participants who used cannabis less often. Heavy cannabis users in the general community have a higher rate of non-fatal stroke or transient ischemic attack than non-cannabis users. © 2015 Public Health Association of Australia.
Full Text Available According to the WHO report, alcohol is the third most significant health risk factor for the global population. There are contrary reports about heavy metals concentrations in patients with alcoholic liver cirrhosis. The aim of this study was to investigate serum concentrations of selected heavy metals in patients with alcoholic liver cirrhosis living in the eastern part of Poland according to cirrhosis stage. The participants came from various hospitals of the Lublin region were enrolled. The study group included 46 male and 16 female patients. The control group consisted of 18 healthy individuals without liver disease. High Performance Ion Chromatography was used to determine the concentrations of metal ions (Cd, Zn, Cu, Ni, Co, Mn, and Pb in serum samples. The concentrations of copper, zinc, nickel, and cobalt were found to be significantly lower in patients with alcoholic liver cirrhosis compared to the control group. The serum concentration of cadmium was significantly higher in patients with advanced alcoholic liver cirrhosis compared to the control group. We hypothesize that disorders of metabolism of heavy metals seem to be the outcome of impaired digestion and absorption, which are common in cirrhosis, improper diet, environmental and occupational exposure.

The current study examined the relationship between mathematics and attention, working memory, and visual memory in children with heavy prenatal alcohol exposure and controls. Subjects were 56 children (29 AE, 27 CON) who were administered measures of global mathematics achievement (WRAT-3 Arithmetic & WISC-III Written Arithmetic), attention, (WISC-III Digit Span forward and Spatial Span forward), working memory (WISC-III Digit Span backward and Spatial Span backward), and visual memory (CANTAB Spatial Recognition Memory and Pattern Recognition Memory). The contribution of cognitive domains to mathematics achievement was analyzed using linear regression techniques. Attention, working memory, and visual memory data were entered together on Step 1 followed by group on Step 2, and the interaction terms on Step 3. Model 1 accounted for a significant amount of variance in both mathematics achievement measures; however, model fit improved with the addition of group on Step 2. Significant predictors of mathematics achievement were Spatial Span forward and backward and Spatial Recognition Memory. These findings suggest that deficits in spatial processing may be related to math impairments seen in FASD. In addition, prenatal alcohol exposure was associated with deficits in mathematics achievement, above and beyond the contribution of general cognitive abilities.

A neurobiological model of risk-taking suggests that differential timing in the maturation of the brain networks associated with emotional processing and cognitive control may predispose adolescents to risky behavior, including alcohol and other substance use. Heavy alcohol use during adolescence has been shown to alter normative brain functioning, though it remains unknown whether alterations normalize with sustained abstinence or persist after cessation of use. The present study utilized fM...

Chronic, excessive ethanol intake has been linked with various electrical instabilities, conduction disturbances, and even sudden cardiac death, but the underlying cause for the latter is insufficiently delineated. We studied surface electrocardiography (ECG) in a community-dwelling cohort with moderate-to-heavy daily alcohol intake (grouped as >90g/day, ≤90g/day, and nonintake). Compared with nonintake, heavier alcohol users showed markedly widened QRS duration and higher prevalence of QRS fragmentation (64.3%, 50.9%, and 33.7%, respectively, χ 2 12.0, both pchronically given a 4% or 6% alcohol diet and showed dose-related slower action potential upstroke, reduced resting membrane potential, and disorganized or decreased intraventricular conduction (all pChronic excessive alcohol ingestion is associated with dose-related phenotypic intraventricular conduction disturbances and QRS fragmentation that can be recapitulated in mice. The mechanisms may involve suppressed gap junction and sodium channel functions, together with enhanced cardiac fibrosis that may contribute to arrhythmogenesis. Copyright © 2017 Elsevier Ltd.

Neuroeconomics integrates concepts and methods from psychology, economics, and cognitive neuroscience to understand how the brain makes decisions. In economics, demand refers to the relationship between a commodity's consumption and its cost, and, in behavioral studies, high alcohol demand has been consistently associated with greater alcohol misuse. Relatively little is known about how the brain processes demand decision making, and the current study is an initial investigation of the neural correlates of alcohol demand among heavy drinkers. Using an event-related functional magnetic resonance imaging (fMRI) paradigm, participants (N=24) selected how much they would drink under varying levels of price. These choices determined access to alcohol during a subsequent bar laboratory self-administration period. During decisions to drink in general, greater activity was present in multiple distinct subunits of the prefrontal and parietal cortices. In contrast, during decisions to drink that were demonstrably affected by the cost of alcohol, significantly greater activation was evident in frontostriatal regions, suggesting an active interplay between cognitive deliberation and subjective reward value. These choices were also characterized by significant deactivation in default mode network regions, suggesting suppression resulting from greater cognitive load. Across choice types, the anterior insula was notably recruited in diverse roles, further implicating the importance of interoceptive processing in decision-making behavior. These findings reveal the neural signatures subserving alcohol cost-benefit decision making, providing a foundation for future clinical applications of this paradigm and extending this approach to understanding the neural correlates of demand for other addictive commodities.

Full Text Available Depression is a highly heterogeneous condition, and identifying how symptoms present in various groups may greatly increase our understanding of its etiology. Importantly, Major Depressive Disorder is strongly linked with Substance Use Disorders, which may ameliorate or exacerbate specific depression symptoms. It is therefore quite plausible that depression may present with different symptom profiles depending on an individual's substance use status. Given these observations, it is important to examine the underlying construct of depression in groups of substance users compared to non-users. In this study we use a non-clinical sample to examine the measurement structure of the Beck Depression Inventory (BDI-II in non-users and frequent-users of various substances. Specifically, measurement invariance was examined across those who do vs. do not use alcohol, nicotine, and cannabis. Results indicate strict factorial invariance across non-users and frequent-users of alcohol and cannabis, and metric invariance across non-users and frequent-users of nicotine. This implies that the factor structure of the BDI-II is similar across all substance use groups.

To evaluate a widely used intervention to reduce college student alcohol use, we studied student drinking patterns at colleges that employed social norms marketing programs and those that did not. We examined responses of students in the Harvard School of Public Health College Alcohol Study (CAS) 1997, 1999 and 2001 data sets at 37 colleges that employed social norms marketing programs and at 61 that did not. Information about the students' drinking behavior and their familiarity with social norms marketing messages at their schools was analyzed, as were college administrators' reports about the implementation of social norms marketing campaigns. Schools were grouped on the basis of student reports of exposure to programmatic materials. Trend analyses were conducted on seven standard measures of alcohol consumption, including annual and 30-day use, frequency, usual quantity and volume consumed, heavy episodic use, and drunkenness. Almost half of the CAS colleges sampled adopted social norms programs. Those that did were more likely to have large enrollments, not to be religiously affiliated and to have high rates of alcohol use. No decreases were noted in any of the seven measures of alcohol use at schools with social norms programs, even when student exposure and length of program existence were considered. Increases in measures of monthly alcohol use and total volume consumed, however, were observed at schools employing social norms programs. This study does not provide evidence to support the effectiveness of social norms marketing programs, as currently utilized, in reducing alcohol use among college students.

Alcohol Myopia Theory (AMT; Steele & Josephs, 1990) purports that alcohol facilitates aggression by narrowing attentional focus onto salient and instigatory cues common to conflict situations. However, few tests of its counterintuitive prediction - that alcohol may decrease aggression when inhibitory cues are most salient - have been conducted. The present study examined whether an AMT-inspired self-awareness intervention manipulation would reduce heavy drinking men's intoxicated aggression toward women and also examined whether a relevant individual variable, locus of control, would moderate this effect. Participants were 102 intoxicated male heavy drinkers who completed a self-report measure of locus of control and completed the Taylor Aggression Paradigm (Taylor, 1967). In this task, participants administered electric shocks to, and received electric shocks from, a fictitious female opponent while exposed to an environment saturated with or devoid of self-awareness cues. Results indicated that the self-awareness manipulation was associated with less alcohol-related aggression toward the female confederate for men who reported an internal, but not an external, locus of control. Findings support AMT as a theoretical framework to inform preventative interventions for alcohol-related aggression and highlight the importance of individual differences in receptivity to such interventions.

Minority stress theory is one of the primary theories used to understand substance use among lesbian, gay, and bisexual populations. This study tested whether drinking to cope with stress (DTC), loneliness, and gay community participation (GCP) mediated the relationship between one type of minority stress (i.e., internalized heterosexism) and behavioral health outcomes. Using secondary data analysis and the PROCESS procedure, relationships between internalized heterosexism, the mediators (DTC, loneliness, and GCP), and outcomes (heavy drinking, alcohol problems, and psychological distress) were explored, both cross-sectionally and in a lagged manner, among both treatment-seeking and non-treatment-seeking problem drinking men who have sex with men. Problem drinkers (N = 187) were assessed, provided brief normative feedback about their drinking, given the choice to receive brief alcohol use disorder treatment or change on their own, and then followed for 9 months. Cross-sectional findings revealed that internalized heterosexism was significantly associated with heavy drinking, alcohol problems, and psychological distress. DTC emerged as a significant mediator of internalized heterosexism for all the health outcomes. Loneliness and GCP were significant mediators of internalized heterosexism for alcohol problems and psychological distress. Multiple mediation models reveal that all three mediators significantly contribute to internalized heterosexism's effect on health outcomes. Lagged analyses did not yield any significant indirect effects. DTC, loneliness, and GCP all play an integral, mediational role in the relationship between internalized heterosexism and alcohol problems and psychological distress. Findings underscore the necessity of addressing internalized heterosexism in psychosocial interventions along with coping skills training, emphasizing culturally relevant social support and loneliness.

Attentional bias for alcohol cues increases craving and subsequent alcohol consumption. Override processes can be used to disengage attention from alcohol cues. This requires self-control and implies that depletion of self-control would impair the ability to disengage attention from alcohol cues.

In this report, the European Environment Agency (EEA) presents updated estimates of the external costs of air pollution for different categories of heavy goods vehicles (HGVs). The amended Eurovignette Directive (2011/76/EU) relating to the charging of HGVs for use of major European motorways prescribes that from 2013, Member States may include air pollution costs in any charging structure for roads under the Trans-European Network (TEN-T) and for comparable domestic motorways. The tables published here provide the basis for the inclusion of a vehicle-specific air pollution component in road user charges. Air pollution costs have been calculated on the basis of the formula prescribed in the directive, taking into account the fact that road transport emissions are mixed in a low volume of air. Following Article 9 in the Eurovignette Directive, additional revenues from external-cost charges must be used by Member States to benefit the transport sector and promote sustainable mobility. Making use of scientific developments subsequent to the 2007 Handbook of external costs (Maibach et al., 2008), the EEA is able to provide an updated estimate of the external costs of air pollution from road transport. The tables in this report indicate for each country and for the relevant vehicle categories, estimates of the external costs of air pollution in 2010 prices. The high level of detail gives member countries an informed basis to group the vehicle categories for administrative purposes. The tables also include estimates for three non-EU member countries of the EEA, of which one (Switzerland) pioneered the first HGV road user charge in Europe. (LN)

Full Text Available AIM: To analyze alcohol use, clinical data and laboratory parameters that may affect FIB-4, an index for measuring liver fibrosis, in HCV-monoinfected and HCV/HIV-coinfected drug users. PATIENTS AND METHODS: Patients admitted for substance abuse treatment between 1994 and 2006 were studied. Socio-demographic data, alcohol and drug use characteristics and clinical variables were obtained through hospital records. Blood samples for biochemistry, liver function tests, CD4 cell count, and serology of HIV and HCV infection were collected at admission. Multivariate linear regression was used to analyze the predictors of FIB-4 increase. RESULTS: A total of 472 (83% M, 17% F patients were eligible. The median age at admission was 31 years (Interquartile range (IQR 27-35 years, and the median duration of drug use was 10 years (IQR 5.5-15 years. Unhealthy drinking (>50 grams/day was reported in 32% of the patients. The FIB-4 scores were significantly greater in the HCV/HIV-coinfected patients (1.14, IQR 0.76-1.87 than in the HCV-monoinfected patients (0.75, IQR 0.56-1.11 (p<0.001. In the multivariate analysis, unhealthy drinking (p = 0.034, lower total cholesterol (p = 0.042, serum albumin (p<0.001, higher GGT (p<0.001 and a longer duration of addiction (p = 0.005 were independently associated with higher FIB-4 scores in the HCV-monoinfected drug users. The effect of unhealthy drinking on FIB-4 scores disappeared in the HCV/HIV-coinfected patients, whereas lower serum albumin (p<0.001, a lower CD4 cell count (p = 0.006, higher total bilirubin (p<0.001 and a longer drug addiction duration (p<0.001 were significantly associated with higher FIB-4 values. CONCLUSIONS: Unhealthy alcohol use in the HCV-monoinfected patients and HIV-related immunodeficiency in the HCV/HIV-coinfected patients are important risk factors associated with liver fibrosis in the respective populations.

Recreational marijuana legalization (RML) went into effect in Oregon in July 2015. RML is expected to influence marijuana use by adolescents and young adults in particular, and by those with a propensity for substance use. We sought to quantify changes in rates of marijuana use among college students in Oregon from pre- to post-RML relative to college students in other states across the same time period. Repeated cross-sectional survey data from the 2012-16 administrations of the Healthy Minds Study. Seven 4-year universities in the United States. There were 10 924 undergraduate participants. One large public Oregon university participated in 2014 and 2016 (n = 588 and 1115, respectively); six universities in US states where recreational marijuana use was illegal participated both in 2016 and at least once between 2012 and 2015. Self-reported marijuana use in the past 30 days (yes/no) was regressed on time (pre/post 2015), exposure to RML (i.e. Oregon students in 2016) and covariates using mixed-effects logistic regression. Moderation of RML effects by recent heavy alcohol use was examined. Rates of marijuana use increased from pre- to post-2015 at six of the seven universities, a trend that was significant overall. Increases in rates of marijuana use were significantly greater in Oregon than in comparison institutions, but only among students reporting recent heavy alcohol use. Rates of Oregon college students' marijuana use increased (relative to that of students in other states) following recreational marijuana legislation in 2015, but only for those who reported recent heavy use of alcohol. Such alcohol misuse may be a proxy for vulnerabilities to substance use or lack of prohibitions (e.g. cultural) against it. © 2017 Society for the Study of Addiction.

We know little about how social media alcohol marketing is utilized for alcohol promotion in different national contexts. There does not appear to be any academic work on online exposure to alcohol marketing via social media in India, and most of the limited research in Australia has focused on Facebook. Hence, the present study extends previous research by investigating alcohol promotion conducted on an under-researched form of social media (YouTube) in two contrasting geographic contexts. This study examines and compares the types of strategies used by marketers on Indian and Australian alcohol brands with the greatest YouTube presence, and the extent to which users engage with these strategies. The 10 alcohol brands per country with the greatest YouTube presence were identified based on the number of 'subscriptions'. The number of videos, views per video, and the type of content within the videos were collected for each brand. The data were analyzed using an inductive coding approach, using NVivo 10. The targeted brands had gathered 98,881 subscriptions (Indian brands: n = 13,868; Australian brands: n = 85,013). The type of marketing strategies utilized by brands were a mix of those that differed by country (e.g. sexually suggestive content in India and posts related to the brand's tradition or heritage in Australia) and generic approaches (e.g. encouraging time- and event-specific drinking; demonstrations of food/cocktail recipes; camaraderie; competitions and prize draws; and brand sponsorship at music, sports, and fashion events). This cross-national comparison demonstrates that YouTube provides alcohol marketers with an advertising platform where they utilize tailored marketing approaches to cater to specific national contexts and develop content on the cultural meanings users invoke in their interactions with these strategies. Those exposed to alcohol marketing on YouTube are likely to include those under the legal drinking age.

To compare the clinical effectiveness and cost-effectiveness of a stepped-care intervention versus a minimal intervention for the treatment of older hazardous alcohol users in primary care. Multi-centre, pragmatic RCT, set in Primary Care in UK. Patients aged ≥ 55 years scoring ≥ 8 on the Alcohol Use Disorders Identification Test were allocated either to 5-min of brief advice or to 'Stepped Care': an initial 20-min of behavioural change counselling, with Step 2 being three sessions of Motivational Enhancement Therapy and Step 3 referral to local alcohol services (progression between each Step being determined by outcomes 1 month after each Step). Outcome measures included average drinks per day, AUDIT-C, alcohol-related problems using the Drinking Problems Index, health-related quality of life using the Short Form 12, costs measured from a NHS/Personal Social Care perspective and estimated health gains in quality adjusted life-years measured assessed EQ-5D. Both groups reduced alcohol consumption at 12 months but the difference between groups was small and not significant. No significant differences were observed between the groups on secondary outcomes. In economic terms stepped care was less costly and more effective than the minimal intervention. Stepped care does not confer an advantage over a minimal intervention in terms of reduction in alcohol use for older hazardous alcohol users in primary care. However, stepped care has a greater probability of being more cost-effective. Current controlled trials ISRCTN52557360. A stepped care approach was compared with brief intervention for older at-risk drinkers attending primary care. While consumption reduced in both groups over 12 months there was no significant difference between the groups. An economic analysis indicated the stepped care which had a greater probability of being more cost-effective than brief intervention. © The Author 2017.

Full Text Available This paper provides a deeper understanding of the role of social influences on positive eWOM behaviour (PeWOM of heavy-users of online communities. Drawing on Social Interaction Utility Framework, Group Marketing and Social Learning Theories, we develop and test a research model integrating the interactions between the social climate of a website and Interpersonal Influences in PeWOM. 262 Spanish heavy-users of online communities were selected and the data analysed using partial least squares equation modelling. Overall, the model explains 59% of the variance of PeWOM on online communities. Findings reveal that interaction with other members of the online community (Social Presence is the main predictor of PeWOM. Social Identity is a mediator between Social Presence and PeWOM. Interpersonal Influence has an important role as a moderator variable; the greater the impact of Interpersonal Influence, the stronger the relationship between Social Presence and PeWOM.

Alcohol is the most commonly used psychoactive substance worldwide. It is considered to increase social cohesion, and to play a part both in the development and expression of identity. Alcohol is, however, also associated with a range of adverse effects for the individual, and involves a great financial and social burden for society. Social media has currently become very popular commodity for social bonding, identity formation and expression, and social influence. This thesis consists of thr...

Illicit stimulants are often combined with alcohol in nightlife entertainment districts, an environment where aggressive behaviour commonly occurs. While alcohol and methamphetamine use are each associated with aggressive behaviour, relatively little is known about the impact of the combined use of alcohol and amphetamine-type stimulants (i.e., ecstasy [MDMA] and methamphetamine) on aggression. Analysis of longitudinal data from a population-based sample of Australian young adult amphetamine-type stimulant users (n=248) to examine: (a) prevalence and timing of simultaneous alcohol and amphetamine-type stimulant use and (b) predictors of ecstasy- and methamphetamine-related aggression and hostility. Prediction models of ecstasy- and methamphetamine-related aggression and hostility were developed using multivariate logistic regression. Simultaneous alcohol consumption and amphetamine-type stimulant use was prevalent, with drinking generally occurring before consuming amphetamine-type stimulants and while 'high'. Methamphetamine-related aggression and hostility was significantly associated with recurrent risky simultaneous methamphetamine and alcohol use (Adjusted Odds Ratio [AOR] 2.74, 95% CI 1.09-6.89), a high frequency and increasing use methamphetamine trajectory (AOR 7.23, 95% CI 1.27-41.03), and high trait aggression (AOR 5.78, 95% CI 2.53-13.20). In contrast, only trait aggression (moderate: AOR 3.01, 95% CI 1.55-5.84; high: AOR 5.02, 95% CI 2.38-10.61) was associated with ecstasy-related aggression and hostility. These findings indicate a link between risky patterns of simultaneous alcohol and methamphetamine use and methamphetamine-related aggression and hostility, independent of separate use of alcohol, methamphetamine and cannabis, trait aggression, psychosis, and gender. The policy challenges of amphetamine-type stimulant and alcohol use require a targeted, multidisciplinary approach. Copyright © 2017 Elsevier Ltd. All rights reserved.

We estimate the effect on light, moderate and heavy consumers of alcohol from implementing a minimum unit price for alcohol (MUP) compared with a uniform volumetric tax. We analyse scanner data from a panel survey of demographically representative households (n = 885) collected over a one-year period (24 Jan 2010-22 Jan 2011) in the state of Victoria, Australia, which includes detailed records of each household's off-trade alcohol purchasing. The heaviest consumers (3% of the sample) currently purchase 20% of the total litres of alcohol (LALs), are more likely to purchase cask wine and full strength beer, and pay significantly less on average per standard drink compared to the lightest consumers (A$1.31 [95% CI 1.20-1.41] compared to $2.21 [95% CI 2.10-2.31]). Applying a MUP of A$1 per standard drink has a greater effect on reducing the mean annual volume of alcohol purchased by the heaviest consumers of wine (15.78 LALs [95% CI 14.86-16.69]) and beer (1.85 LALs [95% CI 1.64-2.05]) compared to a uniform volumetric tax (9.56 LALs [95% CI 9.10-10.01] and 0.49 LALs [95% CI 0.46-0.41], respectively). A MUP results in smaller increases in the annual cost for the heaviest consumers of wine ($393.60 [95% CI 374.19-413.00]) and beer ($108.26 [95% CI 94.76-121.75]), compared to a uniform volumetric tax ($552.46 [95% CI 530.55-574.36] and $163.92 [95% CI 152.79-175.03], respectively). Both a MUP and uniform volumetric tax have little effect on changing the annual cost of wine and beer for light and moderate consumers, and likewise little effect upon their purchasing. While both a MUP and a uniform volumetric tax have potential to reduce heavy consumption of wine and beer without adversely affecting light and moderate consumers, a MUP offers the potential to achieve greater reductions in heavy consumption at a lower overall annual cost to consumers.

Ghrelin, an orexigenic peptide, acts on growth hormone secretagogue receptors (GHS-R1A), expressed in the hypothalamus as well as in important reward nodes such as the ventral tegmental area. Interestingly, ghrelin has been found to activate an important part of the reward systems, i.e., the cholinergic-dopaminergic reward link. Additionally, the rewarding and neurochemical properties of alcohol are, at least in part, mediated via this reward link. There is comorbidity between alcohol dependence and eating disorders. Thus, plasma levels of ghrelin are altered in patients with addictive behaviors such as alcohol and nicotine dependence and in binge eating disorder. This overlap prompted as to investigate the pro-ghrelin and GHS-R1A genes in a haplotype analysis of heavy alcohol-using individuals. A total of 417 Spanish individuals (abstainers, moderate, and heavy alcohol drinkers) were investigated in a haplotype analysis of the pro-ghrelin and GHS-R1A genes. Tag SNPs were chosen using HapMap data and the Tagger and Haploview softwares. These SNPs were then genotyped using TaqMan Allelic Discrimination. SNP rs2232165 of the GHS-R1A gene was associated with heavy alcohol consumption and SNP rs2948694 of the same gene as well as haplotypes of both the pro-ghrelin and the GHS-R1A genes were associated with body mass in heavy alcohol consuming individuals. The present findings are the first to disclose an association between the pro-ghrelin and GHS-R1A genes and heavy alcohol use, further strengthening the role of the ghrelin system in addictive behaviors and brain reward.
Full Text Available A potentially powerful predictor for the course of drug (abuse is the approach-bias, that is, the pre-reflective tendency to approach rather than avoid drug-related stimuli. Here we investigated the neural underpinnings of cannabis approach and avoidance tendencies. By elucidating the predictive power of neural approach-bias activations for future cannabis use and problem severity, we aimed at identifying new intervention targets. Using functional Magnetic Resonance Imaging (fMRI, neural approach-bias activations were measured with a Stimulus Response Compatibility task (SRC and compared between 33 heavy cannabis users and 36 matched controls. In addition, associations were examined between approach-bias activations and cannabis use and problem severity at baseline and at six-month follow-up. Approach-bias activations did not differ between heavy cannabis users and controls. However, within the group of heavy cannabis users, a positive relation was observed between total lifetime cannabis use and approach-bias activations in various fronto-limbic areas. Moreover, approach-bias activations in the dorsolateral prefrontal cortex (DLPFC and anterior cingulate cortex (ACC independently predicted cannabis problem severity after six months over and beyond session-induced subjective measures of craving. Higher DLPFC/ACC activity during cannabis approach trials, but lower activity during cannabis avoidance trials were associated with decreases in cannabis problem severity. These findings suggest that cannabis users with deficient control over cannabis action tendencies are more likely to develop cannabis related problems. Moreover, the balance between cannabis approach and avoidance responses in the DLPFC and ACC may help identify individuals at-risk for cannabis use disorders and may be new targets for prevention and treatment.

Investigations of drinking behavior across military deployment cycles are scarce, and few prospective studies have examined risk factors for post-deployment alcohol misuse. Prevalence of alcohol misuse was estimated among 4645 US Army soldiers who participated in a longitudinal survey. Assessment occurred 1-2 months before soldiers deployed to Afghanistan in 2012 (T0), upon their return to the USA (T1), 3 months later (T2), and 9 months later (T3). Weights-adjusted logistic regression was used to evaluate associations of hypothesized risk factors with post-deployment incidence and persistence of heavy drinking (HD) (consuming 5 + alcoholic drinks at least 1-2×/week) and alcohol or substance use disorder (AUD/SUD). Prevalence of past-month HD at T0, T2, and T3 was 23.3% (s.e. = 0.7%), 26.1% (s.e. = 0.8%), and 22.3% (s.e. = 0.7%); corresponding estimates for any binge drinking (BD) were 52.5% (s.e. = 1.0%), 52.5% (s.e. = 1.0%), and 41.3% (s.e. = 0.9%). Greater personal life stress during deployment (e.g., relationship, family, or financial problems) - but not combat stress - was associated with new onset of HD at T2 [per standard score increase: adjusted odds ratio (AOR) = 1.20, 95% CI 1.06-1.35, p = 0.003]; incidence of AUD/SUD at T2 (AOR = 1.54, 95% CI 1.25-1.89, p risk of alcohol-related problems post-deployment.

The acute and chronic effects of dronabinol [medicinal Δ(9) -tetrahydrocannabinol (THC)] on actual driving performance and the Standard Field Sobriety Test (SFST) were assessed. It was hypothesized that occasional users would be impaired on these tests and that heavy users would show less impairment due to tolerance. Double-blind, placebo-controlled, randomized, three-way cross-over study. Twelve occasional and 12 heavy cannabis users (14 males/10 females) received single doses of placebo, 10 and 20 mg dronabinol. Standard deviation of lateral position (SDLP; i.e. weaving) is the primary measure of road-tracking control. Time to speed adaptation (TSA) is the primary reaction-time measure in the car-following test. Percentage of impaired individuals on the SFST and subjective high on a visual analogue scale were secondary measures. Superiority tests showed that SDLP (P = 0.008) and TSA (P = 0.011) increased after dronabinol in occasional users. Equivalence tests demonstrated that dronabinol-induced increments in SDLP were bigger than impairment associated with BAC of 0.5 mg/ml in occasional and heavy users, although the magnitude of driving impairment was generally less in heavy users. The SFST did not discriminate between conditions. Levels of subjective high were comparable in occasional and heavy users. Dronabinol (medicinal tetrahydrocannabinol) impairs driving performance in occasional and heavy users in a dose-dependent way, but to a lesser degree in heavy users due possibly to tolerance. The Standard Field Sobriety Test is not sensitive to clinically relevant driving impairment caused by oral tetrahydrocannabinol. © 2012 The Authors.

To determine the threshold index of sweet and salty tastes in alcoholics undergoing treatment. Taste threshold was assessed using type 3-Alternative Forced Choice in a control group (92 non-alcoholic volunteers) and a test group (92 alcoholics in therapy). The test group completed a structured questionnaire on lifestyle and habits. Significant difference were found between the threshold rates found in the test (3.78) and control groups (1.39). In the salty stimulus, no significant difference was noted in the threshold detection between the control (0.17) and test groups (0.30). A significant correlation was observed between the index Pearson's threshold to sweet taste in the test group and their reported alcohol consumption. The test group reported characteristics such as loss of appetite (93%), weight loss during consumption (62%) and weight gain after quitting drinking (72%). That the alcoholic group reported less sensitivity to sweet taste suggests that drinking habits may influence choice of foods, with a greater preference for foods with higher sucrose concentration. This contribute to poor health, because excess consumption of sugar raises risk for several diseases. No conclusive results were found for the salty stimulus. © The Author 2015.

During alcohol intoxication the human brain increases metabolism of acetate and decreases metabolism of glucose as energy substrate. Here we hypothesized that chronic heavy drinking facilitates this energy substrate shift both for baseline and stimulation conditions. To test this hypothesis we compared the effects of alcohol intoxication (0.75g/kg alcohol versus placebo) on brain glucose metabolism during video-stimulation (VS) versus when given with no-stimulation (NS), in 25 heavy drinkers (HD) and 23 healthy controls each of whom underwent four PET- 18 FDG scans. We showed that resting whole-brain glucose metabolism (placebo-NS) was lower in HD than controls (13%, p=0.04); that alcohol (compared to placebo) decreased metabolism more in HD (20±13%) than controls (9±11%, p=0.005) and in proportion to daily alcohol consumption (r=0.36, p=0.01) but found that alcohol did not reduce the metabolic increases in visual cortex from VS in either group. Instead, VS reduced alcohol-induced decreases in whole-brain glucose metabolism (10±12%) compared to NS in both groups (15±13%, p=0.04), consistent with stimulation-related glucose metabolism enhancement. These findings corroborate our hypothesis that heavy alcohol consumption facilitates use of alternative energy substrates (i.e. acetate) for resting activity during intoxication, which might persist through early sobriety, but indicate that glucose is still favored as energy substrate during brain stimulation. Our findings are consistent with reduced reliance on glucose as the main energy substrate for resting brain metabolism during intoxication (presumably shifting to acetate or other ketones) and a priming of this shift in heavy drinkers, which might make them vulnerable to energy deficits during withdrawal

This study examined the relationship between living arrangement and heavy episodic drinking among college students in the United States. Using social learning theory as a framework, it was hypothesized that vicarious learning of peer and family alcohol-use norms would mediate the effects of living arrangement on heavy episodic drinking. Analyses were conducted using data from the 2001 Harvard School of Public Health College Alcohol Study, a national survey of full-time undergraduate students attending 4-year colleges or universities in the United States (N = 10,008). Logistic regression models examined the relationship between heavy episodic drinking and various measures of living arrangement and vicarious learning/social norms. Mediation of the effects of living arrangement was tested using both indirect and direct methods. Both student living arrangement and vicarious-learning/social-norm variables remained significant predictors of heavy episodic drinking in multivariate models when controlling for a variety of individual characteristics. Slight mediation of the effects of living arrangement on heavy episodic drinking by vicarious learning/social norms was confirmed for some measures. Although vicarious learning of social norms does appear to play a role in the association between living arrangement and alcohol use, other processes may underlie the relationship. These findings suggest that using theory alongside empirical evidence to inform the manipulation of living environments could present a promising policy strategy to reduce alcohol-related harm in collegiate contexts.
Alcohol is one of the most widely used addictive substances. It can be assumed that everybody encounters alcohol--ethanol in various forms and concentrations in the course of their lives. A global and social problem of our civilization is alcohol consumption which has a rising trend. Since 1989 the consumption of alcoholic beverages is rising and the mean annual consumption of concentrated ethanol per head is cea 10 litres. In ethanol abuse the organism is damaged not only by ethanol alone but in particular by substances formed during its metabolism. Its detailed knowledge is essential for the knowledge and investigations of the metabolic and toxic effect of ethanol on the organism. Ingested alcohol is in 90-98% eliminated from the organism by three known metabolic pathways: 1-alcohol dehydrogenase, 2-the microsomal ethanol oxidizing system and 3-catalase. Alcohol is a frequent important risk factor of serious "diseases of civilization" such as IHD, hypertension, osteoporosis, neoplastic diseases. Cirrhosis of the liver and chronic pancreatitis are the well known diseases associated with alcohol ingestion and also their most frequent cause. It is impossible to list all organs and diseases which develop as a result of alcohol consumption. It is important to realize that regular and "relatively" small amounts in the long run damage the organism and may be even fatal.

Quite a number of cyber-attacks to be place against supercomputers that provide highperformance computing (HPC) services to public researcher. Particularly, although the secure shell protocol (SSH) brute-force attack is one of the traditional attack methods, it is still being used. Because stealth attacks that feign regular access may occur, they are even harder to detect. In this paper, we introduce methods to detect SSH brute-force attacks by analyzing the server's unsuccessful access logs and the firewall's drop events in a multi-user environment. Then, we analyze the durations of the SSH brute-force attacks that are detected by applying these methods. The results of an analysis of about 10 thousands attack source IP addresses show that the behaviors of abnormal users using SSH brute-force attacks are based on human dynamic characteristics of a typical heavy-tailed distribution.

The aim of this study was to investigate the characteristics of drinkers who claim to be hangover immune and compare them with drinkers who do report having hangovers. Methods: A total of 36 social drinkers participated in a naturalistic study consisting of a hangover day (alcohol consumed and a control day (no alcohol consumed. Data were collected on alcohol consumption, demographics, sleep, next-day adverse effects, and mood. Data from drinkers with a hangover (N=18 were compared with data from drinkers who claim to be hangover immune (N=18. Results: Drinkers with a hangover reported drowsiness-related symptoms, symptoms related to reduced cognitive functioning, and classic hangover symptoms such as headache, nausea, dizziness, weakness, and stomach pain. Corresponding mood changes comprised increased feelings of depression, anger–hostility, fatigue, and reduced vigor–activity. In contrast, hangover-immune drinkers reported relatively few hangover symptoms, with only mild corresponding severity scores. The reported symptoms were limited to drowsiness-related symptoms such as sleepiness and being tired. The classic hangover symptoms were usually not reported by these drinkers. Conclusion: In contrast to drinkers with a hangover, for those who claim to be hangover immune, next-day adverse effects of alcohol consumption are limited to a mild increase in

This study investigates the potential heterogeneity of ecstasy or MDMA (3,4-methylenedioxy-N-methylamphetamine) users. Data came from the 2001–2002 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Latent class analysis (LCA) and multinomial logistic regression procedures were used to identify subtypes of ecstasy users. Approximately 1.6% (n=562) of adult participants (N=43,093) reported lifetime ecstasy use. LCA identified three subtypes of ecstasy users. Class 1 exhibited pervasive use of most drug classes (ecstasy–polydrug users, 37%). Class 2 reported a high rate of use of marijuana and cocaine and a moderate use of amphetamines (ecstasy–marijuana–stimulant users, 29%). Class 3 was characterized by a high rate of use of marijuana and a low use of primarily prescription-type drugs (ecstasy– marijuana users, 34%). Subtypes were distinguished by family income, history of substance abuse treatment, and familial substance abuse. Class 1 exhibited the highest prevalence of disorders related to the use of marijuana (77%), tobacco (66%), amphetamines (36%), opioids (35%), sedatives (31%), and tranquilizers (30%). The recent resurgence in ecstasy use among adults underscores the need to monitor trends in its use. PMID:19874166

The Organisation International de la Vigne et du Vin (OIV) fixed an uppermost level for some heavy metals in wine. Consequently, the need to determine very low concentration of elements that may be present in wine in trace and ultra trace levels occurred. Inductively coupled plasma mass spectrometry ICP-MS is considered an excellent tool for detailed characterization of the elementary composition of many samples, including samples of drinks. In this study a method of quantitative analysis for the determination of toxic metals (Cr, As, Cd, Ni, Hg, Pb) in wines and slightly alcoholic beverages by ICP-MS was validated. Several parameters have been taken into account and evaluated for the validation of method, namely: linearity, the minimum detection limit, the limit of quantification, accuracy and uncertainty.

To test this hypothesis, we compared the effects of alcohol intoxication (0.75 g/kg alcohol vs placebo) on brain glucose metabolism during video stimulation (VS) versus when given with no stimulation (NS), in 25 heavy drinkers (HDs) and 23 healthy controls, each of whom underwent four PET-(18)FDG scans. We showed that resting whole-brain glucose metabolism (placebo-NS) was lower in HD than controls (13%, p = 0.04); that alcohol (compared with placebo) decreased metabolism more in HD (20 ± 13%) than controls (9 ± 11%, p = 0.005) and in proportion to daily alcohol consumption (r = 0.36, p = 0.01) but found that alcohol did not reduce the metabolic increases in visual cortex from VS in either group. Instead, VS reduced alcohol-induced decreases in whole-brain glucose metabolism (10 ± 12%) compared with NS in both groups (15 ± 13%, p = 0.04), consistent with stimulation-related glucose metabolism enhancement. These findings corroborate our hypothesis that heavy alcohol consumption facilitates use of alternative energy substrates (i.e., acetate) for resting activity during intoxication, which might persist through early sobriety, but indicate that glucose is still favored as energy substrate during brain stimulation. Our findings are consistent with reduced reliance on glucose as the main energy substrate for resting brain metabolism during intoxication (presumably shifting to acetate or other ketones) and a priming of this shift in HDs, which might make them vulnerable to energy deficits during withdrawal.

The effect of adolescent marijuana use on brain development remains unclear despite relaxing legal restrictions, decreased perceived harm, and increasing use rates among youth. The aim of this 3-year prospective study was to evaluate the long-term neurocognitive effects of adolescent marijuana use. Adolescent marijuana users with concomitant alcohol use (MJ + ALC, n = 49) and control teens with limited substance use histories (CON, n = 59) were given neuropsychological and substance use assessments at project baseline, when they were ages 16-19. They were then reassessed 18 and 36 months later. Changes in neuropsychological measures were evaluated with repeated measures analysis of covariance (ANCOVA), controlling for lifetime alcohol use, and examined the effects of group, time, and group by time interactions on cognitive functioning. MJ + ALC users performed significantly worse than controls, across time points, in the domains of complex attention, memory, processing speed, and visuospatial functioning (ps marijuana use onset was associated with poorer processing speed and executive functioning by the 3-year follow-up (ps ≤.02). Frequent marijuana use throughout adolescence and into young adulthood appeared linked to worsened cognitive performance. Earlier age of onset appears to be associated with poorer neurocognitive outcomes that emerge by young adulthood, providing further support for the notion that the brain may be uniquely sensitive to frequent marijuana exposure during the adolescent phase of neurodevelopment. Continued follow-up of adolescent marijuana users will determine the extent of neural recovery that may occur if use abates. (c) 2015 APA, all rights reserved).

Prenatal alcohol exposure is associated with behavioral disinhibition, yet the brain structure correlates of this deficit have not been determined with sufficient detail. We examined the hypothesis that the structure of the anterior cingulate cortex (ACC) relates to inhibition performance in youth with histories of heavy prenatal alcohol exposure (AE, n = 32) and non-exposed controls (CON, n = 21). Adolescents (12-17 years) underwent structural magnetic resonance imaging yielding measures of gray matter volume, surface area, and thickness across four ACC subregions. A subset of subjects were administered the NEPSY-II Inhibition subtest. MANCOVA was utilized to test for group differences in ACC and inhibition performance and multiple linear regression was used to probe ACC-inhibition relationships. ACC surface area was significantly smaller in AE, though this effect was primarily driven by reduced right caudal ACC (rcACC). AE also performed significantly worse on inhibition speed but not on inhibition accuracy. Regression analyses with the rcACC revealed a significant group × ACC interaction. A smaller rcACC surface area was associated with slower inhibition completion time for AE but was not significantly associated with inhibition in CON. After accounting for processing speed, smaller rcACC surface area was associated with worse (i.e., slower) inhibition regardless of group. Examining processing speed independently, a decrease in rcACC surface area was associated with faster processing speed for CON but not significantly associated with processing speed in AE. Results support the theory that caudal ACC may monitor reaction time in addition to inhibition and highlight the possibility of delayed ACC neurodevelopment in prenatal alcohol exposure.

This paper reports results of an analysis of the association between alcohol intoxication and injection and sexual HIV risk behaviors among 557 Hispanic heroin and cocaine injectors, not in treatment, who were recruited in poor communities in Puerto Rico. Subjects were part of a longitudinal prevention-intervention study aimed at reducing drug use and HIV risk behaviors. Participants reported a high prevalence of co-occurring conditions, particularly symptoms of severe depression (52%) and severe anxiety (37%), measured by Beck's Depression Index and Beck's Anxiety Index, respectively. Alcohol intoxication during the last 30 days was reported by 18% of participants. Associations were found between alcohol intoxication and both injection and sexual risk behaviors. In the bivariate analysis, subjects reporting alcohol intoxication were more likely to inject three or more times per day, pool money to buy drugs, share needles, and share cotton. They were also significantly more likely to have a casual or paying sex partner and to have unprotected sex with these partners. After adjustment, sharing needles and cotton, having sex with a paying partner or casual partner, and exchanging sex for money or drugs were significantly related to alcohol intoxication. HIV prevention programs, to be effective, must address alcohol intoxication and its relation to injection and sexual risk behaviors as a central issue in HIV prevention among drug injectors.

Full Text Available The aims of this study were to assess the impact of ceremonial use of ayahuasca—a psychedelic brew containing N,N-dimethyltryptamine (DMT and β-carboline —and attendance at União do Vegetal (UDV meetings on substance abuse; here we report the findings related to alcohol and tobacco use disorder. A total of 1,947 members of UDV 18+ years old were evaluated in terms of years of membership and ceremonial attendance during the previous 12 months. Participants were recruited from 10 states from all major regions of Brazil. Alcohol and tobacco use was evaluated through questionnaires first developed by the World Health Organization and the Substance Abuse and Mental Health Services Administration. Analyses compared levels of alcohol and tobacco use disorder between the UDV and a national normative sample (n = 7,939. Binomial tests for proportions indicated that lifetime use of alcohol and tobacco was higher in UDV sample compared to the Brazilian norms for age ranges of 25–34 and over 34 years old, but not for the age range of 18–24 years old. However, current use disorders for alcohol and tobacco were significantly lower in the UDV sample than the Brazilian norms. Regression analyses revealed a significant impact of attendance at ayahuasca ceremonies during the previous 12 months and years of UDV membership on the reduction of alcohol and tobacco use disorder.

Cannabis is one of the most commonly used illicit drugs in the United States and is considered to have several adverse health effects. There is evidence suggesting that its recreational use is associated with both increased cardio- and cerebrovascular events. Recently, multiple cases of ischemic and hemorrhagic strokes associated with cannabis use were reported in the literature (Goyal et al., 2017). It has been suggested that cannabis can affect cerebral auto-regulation and vascular tone leading to vasoconstriction and acute ischemic stroke. However, hemorrhagic strokes, which are often seen with sympathomimetic illicit drugs (e.g. cocaine and amphetamines), have rarely been reported due to cannabis. Many cellular mechanisms within non-ischemic tissue post stroke may be augmented by heavy cannabis use. Here, we describe a rapid development of hemorrhage following thrombolytic therapy in a patient with heavy cannabis use with an ischemic stroke. Copyright © 2017 Elsevier Inc. All rights reserved.

This systematic review seeks to expand the description and understanding of late-onset AUD and asks "Which risk factors have been reported for late-onset heavy drinking and AUD?" Using PRISMA guidelines, a literature review and search was performed on May 19, 2015 using the following databases: MEDLINE, EMBASE, PubMed, and PsychInfo. Nine studies were included in the final review. The search revealed that only very few studies have been conducted. Hence, the evidence is limited but suggests that stress, role/identity loss, and friends' approval of drinking are associated with an increased risk for late-onset AUD or heavy drinking, whereas retirement, death of a spouse or a close relative does not increase the risk. Inherent differences in measurements and methodologies precluded a meta-analysis. Therefore, the results presented here are descriptive in nature. Most studies base their conclusions on a certain preconception of older adults with alcohol problems, which leads to a row of circular arguments. The factors that have been measured seem to have changed over time. There has been a lack of focus on the field of late-onset AUD since the 1970s, which possibly has led to misrepresentations and preconceptions on the complex nature of late-onset AUD. There is limited evidence for any specific risk factor for late-onset AUD or heavy drinking. We suggest the adoption of a qualitative approach to uncover what is intrinsic to late-onset AUD followed by quantitative studies with more agreement on methods and definitions.

In the Netherlands, young adults' drinking practices have become an issue of public concern since their drinking levels are high. Heavy drinking can place young adults at an increased risk for developing short- and long-term health-related problems. Current national alcohol prevention programmes focus mainly on adolescents and their parents and paying less systematic attention to young adults. The present study describes the theory and evidence-based development of a web-based brief alcohol intervention entitled What Do You Drink (WDYD). We applied the Intervention Mapping (IM) protocol to combine theory and evidence in the development and implementation of WDYD. The WDYD intervention aims to detect and reduce heavy drinking of young adults who are willing to decrease their alcohol consumption, preferably below the Dutch guidelines of low-risk drinking. According to the IM protocol, the development of WDYD resulted in a structured intervention. Reducing heavy drinking to low-risk drinking was proposed as the behavioural outcome. Motivational interviewing principles and parts of the I-Change Model were used as methods in the development of WDYD, whereas computer tailoring was selected as main strategy. An effect and a process evaluation of the intervention will be conducted. IM was found to be a practical instrument for developing the WDYD intervention tailored to a specific target population in the area of alcohol prevention. © The Author (2013).

It is unusual for purpura to emerge as a result of drinking alcohol. Such a peculiarity was observed in a 55-year-old man with a 30-year history of heavy alcohol use. The Caucasian patient was studied for 11 years during several detoxification treatments. During the last 2 years of that period, purpuric rashes were newly observed. The asymptomatic purpura was limited to both lower limbs, self-limiting with abstinence, and reoccurring swiftly with alcohol relapse. This sequence was observed six times, suggesting a causative role of alcohol or its metabolites. A skin biopsy revealed histological features of purpura pigmentosa progressiva (termed Schamberg's disease). Additionally, alcoholic fatty liver disease markedly elevated serum immunoglobulins (immunoglobulin A and immunoglobulin E), activated T-lymphocytes, and increased C-reactive protein. In addition, moderate combined (cellular and humoral) immunodeficiency was found. Unlike the patient's immunoglobulin A level, his serum immunoglobulin E level fell in the first days of abstinence, which corresponded to the time of purpura decline. Systemic vasculitis and clotting disorders were excluded. The benign character of the purpura was supported by missing circulating immune complexes or complement activation. An alcohol provocation test with vinegar was followed by the development of fresh "cayenne pepper" spots characteristic of Schamberg's disease. This case report demonstrates that Schamberg's disease can be strongly related to alcohol intake, in our patient most likely as a late complication of severe alcoholism with alcoholic liver disease. Immunologic disturbances thereby acquired could have constituted a basis for a hypersensitivity-like reaction after ingestion of alcohol. Schamberg's disease induction by vinegar may point to an involvement of acetate, a metabolite of ethanol.

Neurobiological theories of addiction have highlighted disruption in stress pathways as a central feature of addictive disorders, and pharmacological treatments targeting stress mechanisms hold great promise. This study examines genetic determinants of stress-induced and cue-induced craving in heavy drinkers by testing single-nucleotide polymorphisms (SNPs) of the corticotrophin-releasing hormone binding protein (CRH-BP) gene and the mu-opioid receptor (OPRM1) gene. This study combines guided imagery stress exposure and in vivo alcohol cue exposure in a sample of 64 (23 women) non-treatment-seeking heavy drinkers. Analyses, uncorrected for multiple comparisons, revealed that a tag SNP of the CRH-BP gene (rs10055255) moderated stress-induced craving in this sample. The same SNP predicted greater affective responses to the stress manipulation, including greater levels of subjective tension and negative mood. The Asp40 allele of the OPRM1 was associated with greater cue-induced alcohol craving following the neutral imagery condition. These initial results extend recent preclinical and clinical findings implicating the CRH-BP in stress-related alcoholism and confirm the role of the Asp40 allele of the OPRM1 gene in reward-driven alcohol phenotypes. Human laboratory models of stress and cue-induced craving may be useful in pharmacotherapy development targeting dysregulation of stress systems. Larger studies are needed to validate these preliminary findings, which should also be extended to clinical samples. Copyright © 2010 by the Research Society on Alcoholism.

To identify and characterize patterns of use among a contemporary cohort of current anabolic-androgenic steroid (AAS) users. An anonymous, self-administered, 49-item questionnaire was posted on message boards of Internet websites popular among AAS users and administered via SurveyMonkey from February 1, 2015, to June 1, 2015. Thirty-seven questions were analyzed for this study. A total of 231 male respondents met the inclusion criteria. Most were white, were older than 25 years, were employed with above average income, and had received a formal education beyond high school. Ninety-three percent began using AAS after the age of 18 years, and 81% reported using 400 mg or more of testosterone per week. Factors associated with longer duration of use (>5 years) included higher incomes (≥$75,000, P=.003), increased testosterone dosages (>600 mg per week, P=.007), older age (≥35 years, PInternet was the most common source of testosterone (53%). Ninety-three percent used at least one additional performance-enhancing drug. Seventy-seven percent had routine laboratory tests performed, and 38% reported laboratory abnormalities at some point. Nearly all experienced subjective adverse effects while using and not using testosterone. Fifty-three percent reported use of other illegal substances, most commonly (90%) beginning before AAS initiation. Ten percent had a criminal conviction, 91% of which preceded AAS use. Fifty percent were felonies. The population of AAS users is disparate from that of other drugs of abuse. Laboratory test abnormalities and adverse effects are common and should be taken into account when counseling patients who may be using AASs.

The Kowhai Alcohol and Drug Treatment Unit at Rolleston Prison offers an innovative treatment approach for New Zealand inmates. The development of the program has involved local staff from Public Prisons, Psychological Services, and the Community Probation Service (CPS). This presentation outlines the author's impression of this bold innovation. The primary aim of the program is to reduce recidivism. This is achieved by assisting inmates to recognize the thoughts, emotions, and behaviours that are present in the period preceding and/or during the commission of criminal activity--particularly those that are precipitated and/or maintained by alcohol and drug use. This insight, coupled with the learning of specific coping skills and intensive lifestyle and reintegration planning, leads naturally to the follow-up phase that is conducted in the community. The functional relationship between offending and substance use is far more explicitly addressed in this new program compared with past programs that focused more on substance use.

Full Text Available In Russia, up to half of premature deaths are attributed to hazardous drinking. The respective roles of alcohol and drug use in premature death among people with HIV in Russia have not been described. Criminalization and stigmatization of substance use in Russia may also contribute to mortality. We explored whether alcohol, drug use and risk environment factors are associated with short-term mortality in HIV-infected Russians who use substances. Secondary analyses were conducted using prospective data collected at baseline, 6 and 12-months from HIV-infected people who use substances recruited between 2007-2010 from addiction and HIV care settings in a single urban setting of St. Petersburg, Russia. We used Cox proportional hazards models to explore associations between 30-day alcohol hazardous drinking, injection drug use, polysubstance use and environmental risk exposures (i.e. past incarceration, police involvement, selling sex, and HIV stigma with mortality. Among 700 participants, 59% were male and the mean age was 30 years. There were 40 deaths after a median follow-up of 12 months (crude mortality rate 5.9 per 100 person-years. In adjusted analyses, 30-day NIAAA hazardous drinking was significantly associated with mortality compared to no drinking [adjusted Hazard Ratio (aHR 2.60, 95% Confidence Interval (CI: 1.24-5.44] but moderate drinking was not (aHR 0.95, 95% CI: 0.35-2.59. No other factors were significantly associated with mortality. The high rates of short-term mortality and the strong association with hazardous drinking suggest a need to integrate evidence-based alcohol interventions into treatment strategies for HIV-infected Russians.

Background: Structural imaging studies of cannabis users have found evidence of both cortical and subcortical volume reductions, especially in cannabinoid receptor-rich regions such as the hippocampus and amygdala. However, the findings have not been consistent. In the present study, we examined a sample of adult heavy cannabis users without other substance abuse to determine whether long-term use is associated with brain structural changes, especially in the subcortical regions. Method: We compared the gray matter volume of 14 long-term, heavy cannabis users with non-using controls. To provide robust findings, we conducted two separate studies using two different MRI techniques. Each study used the same sample of cannabis users and a different control group, respectively. Both control groups were independent of each other. First, whole-brain voxel-based morphometry (VBM) was used to compare the cannabis users against 28 matched controls (HC1 group). Second, a volumetric analysis of subcortical regions was performed to assess differences between the cannabis users and a sample of 100 matched controls (HC2 group) obtained from a local database of healthy volunteers. Results: The VBM study revealed that, compared to the control group HC1, the cannabis users did not show cortical differences nor smaller volume in any subcortical structure but showed a cluster ( p users showed significantly larger volumes in the putamen ( p = 0.001) and pallidum ( p = 0.0015). Subtle trends, only significant at the uncorrected level, were also found in the caudate ( p = 0.05) and nucleus accumbens ( p = 0.047). Conclusions: This study does not support previous findings of hippocampal and/or amygdala structural changes in long-term, heavy cannabis users. It does, however, provide evidence of basal ganglia volume increases.

Homeless drug and alcohol users are one of the most marginalised groups in society. They frequently have complex needs and limited social support. In this paper, we explore the role of friendship in the lives of homeless drug and alcohol users living in hostels, using the concepts of 'social capital' and 'recovery capital' to frame the analyses. The study was undertaken in three hostels, each in a different English city, during 2013-2014. Audio recorded semi-structured interviews were conducted with 30 residents (9 females; 21 males) who self-reported drink and/or drug problems; follow-up interviews were completed 4-6 weeks later with 22 participants (6 females; 16 males). Data were transcribed verbatim, coded using the software package MAXQDA, and analysed using Framework. Only 21 participants reported current friends at interview 1, and friendship networks were small and changeable. Despite this, participants desired friendships that were culturally normative. Eight categories of friend emerged from the data: family-like friends; using friends; homeless friends; childhood friends; online-only friends; drug treatment friends; work friends; and mutual interest friends. Routine and regular contact was highly valued, with family-like friends appearing to offer the most constant practical and emotional support. The use of information and communication technologies (ICTs) was central to many participants' friendships, keeping them connected to social support and recovery capital outside homelessness and substance-using worlds. We conclude that those working with homeless drug and alcohol users - and potentially other marginalised populations - could beneficially encourage their clients to identify and build upon their most positive and reliable relationships. Additionally, they might explore ways of promoting the use of ICTs to combat loneliness and isolation.

A study has been made to modify water-soluble poly(vinyl alcohol) (PVA), by grafting acrylic acid and styrene (AAc/Sty) binary monomers using gamma rays as initiator. The factors that affect the preparation process and grafting yield were studied and more economical grafts under the most favorable reaction conditions were obtained. It was found that the high degree of grafting of such system was obtained in presence of ethanol-water mixture in which water plays a significant role in enhancing the graft copolymerization. The critical amount of water to afford maximum grafting yield has been evaluated. The effect of comonomer composition on the grafting yield was also investigated and it was observed that using a mixture of AAc/Sty monomers influence the extent of grafting of each monomer onto the PVA substrate and the phenomenon of synergism occurs during such reaction. Also, degree of grafting increases as the content of the solvent decreases in the reaction medium. The permeation of heavy metals such as Ni and Co through the grafted membranes was investigated and efficiency of separation process is also determined

Ayahuasca is a natural psychedelic brew, which contains dimethyltryptamine (DMT). Its potential as a psychiatric medicine has recently been demonstrated and its non-medical use around the world appears to be growing. We aimed to investigate well-being and problematic alcohol use in ayahuasca users, and ayahuasca's subjective effects. An online, self-selecting, global survey examining patterns of drug use was conducted in 2015 and 2016 (n = 96,901). Questions were asked about: use of ayahuasca, lysergic acid diethylamide (LSD) and magic mushrooms; demographics, current well-being and past-year problematic alcohol use of past-year ayahuasca users and comparison drug users; and subjective effects of ayahuasca and comparison drugs. Ayahuasca users (n = 527) reported greater well-being than both classic psychedelic users (n = 18,138) and non-psychedelic drug-using respondents (n = 78,236). Ayahuasca users reported less problematic drinking than classic psychedelic users, although both groups reported greater problematic drinking than the other respondents. Ayahuasca's acute subjective effects usually lasted for six hours and were most strongly felt one hour after consumption. Within our online, self-selecting survey, ayahuasca users reported better well-being than comparison groups and less problematic drinking than classic psychedelic users. Future longitudinal studies of international samples and randomised controlled trials are needed to dissect the effects of ayahuasca on these outcomes.

Fundamental to supporting hazardous alcohol users are the rationales for reducing alcohol intake highlighted by the users themselves. This study analyses the relative importance of beliefs about pros and cons of drinking in relation to having an intention to reduce intake among both hazardous and moderate alcohol users. Intention to change was assessed in a representative sample of Stockholm's population (n = 4278, response rate 56.5%). Alcohol use was assessed using the Alcohol Use Disorders Identification Test measure. A decisional balance inventory was used to examine various beliefs about the pros and cons of drinking, which covered affect changes, social gains and losses, and possible adverse effects. Independent correlations were determined by logistic regression using a backward exclusion procedure (P > 0.05). Higher ratings of importance were generally related to intent, whether or not the contrast was with having no intent or already having made a reduction. This was especially true for hazardous users. Only two beliefs were independently correlated with change among hazardous users: 'Drinking could get me addicted' and 'Drinking makes me more relaxed/less tense' (pseudo-R2 change rated pro arguments as more important than those with no intent to change. Of the investigated pros and cons, only a few were independently related to intention to change drinking behaviour. These arguments provide interesting topics in consultations. Little support was found for any rational decision making behind the intention to reduce alcohol intake. © The Author 2014.

Previous studies have shown increased sexual risk-taking in experienced MDMA/ecstasy users. The main objectives of this study were to compare levels of sexual risk-taking between a young student sample of predominantly heterosexual MDMA users and alcohol-drinker controls and investigate potential gender differences. Recreational drug use and sexual risk questionnaires were completed by 20 MDMA users (10 females, 10 males) and 20 non-user controls (10 females, 10 males). They were predominantly university students, aged between 20-22 years, mainly heterosexual (n = 37), with three bisexual participants. MDMA users displayed significantly greater levels of sexual risk-taking than the alcohol-drinker controls. It involved significantly higher rates of casual sex, non-condom use during sex, and penetrative sexual risks. This increase in sexual riskiness occurred to a similar extent in males and females. These findings indicate that both female and male ecstasy/MDMA users reported more risky sexual behaviours, than the non-user controls. Further research into the sexual behaviour and sexual risk-taking of heterosexual MDMA users should be conducted because much of the past literature has focused on homosexual participants.

Social context may be an important determinant of drug and alcohol consumption and HIV-related behaviors. To assess the influence of peers on drug users' risk behaviors this study examined the association between individual level and group level behaviors. This analysis reports on the prospective association between baseline self-reported drug and alcohol use of the network members of injection drug users, and self-reported sexual behaviors and alcohol use at 5-month follow-up. Participants were a nontreatment sample of inner-city injection drug users who volunteered for a network-oriented HIV preventive intervention. They were predominantly unemployed, African American males. Of the 71 index participants who completed both the baseline and follow-up interviews, 227 of their drug network members were enrolled in the study. At baseline indexes' sexual risk behaviors were significantly associated with their drug network members' level of crack cocaine use. At follow-up higher levels of alcohol and crack use among drug network members were associated with indexes' reports of multiple sex partners and increased alcohol consumption. Higher levels of crack use among the drug network members were associated with the indexes' reporting casual sex partners at follow-up. These results highlight the importance of studying the role of peer group influence and the social context of risk behaviors.

Background Stress and anxiety are widely considered to be causally related to alcohol craving and consumption, as well as development and maintenance of alcohol use disorder (AUD). However, numerous preclinical and human studies examining effects of stress or anxiety on alcohol use and alcohol?related problems have been equivocal. This study examined relationships between scores on self?report anxiety, anxiety sensitivity, and stress measures and frequency and intensity of recent drinking, al...

Harmful use of alcohol is one of the globally recognized causes of health hazards. There are no data on alcohol consumption from Andaman and Nicobar Islands. The objective of the study was to assess the prevalence and pattern of alcohol use among the population of Andaman and Nicobar Islands, India. A representative sample of 18,018 individuals aged ≥14 years were chosen by multistage random sampling and administered a structured instrument, a modified version of the Gender, Alcohol, and Culture: An International Study (GENACIS) which included sociodemographic details and Alcohol Use Disorders Identification Test (AUDIT). The overall prevalence of alcohol consumption was 35% among males and over 6.0% in females, aged 14 and above. Two out of every five alcohol users fit into a category of hazardous drinkers. One-fourth of the total users (23%) are alcohol dependents. Both the hazardous drinking and dependent use are high among males compared to females. Almost 18.0% of male drinkers and 12.0% of female drinkers reported heavy drinking on typical drinking occasions. The predominant beverages consumed were in the category of homebrews such as toddy and handia. The present study highlights the magnitude of hazardous drinking and alcohol dependence in Andaman and Nicobar Islands, India and the complex sociocultural differences in the pattern of alcohol use. Based on the AUDIT data, among the population of Andaman and Nicobar Islands (aged 14 and above), one out of ten requires active interventions to manage the harmful impact of alcohol misuse.

Web-based brief alcohol interventions are effective in reducing alcohol use among students when measured at limited follow-up time points. To date, no studies have tested Web-based brief alcohol intervention effectiveness over time by using a large number of measurements. Testing whether the What Do You Drink (WDYD) Web-based brief alcohol intervention can sustain a reduction in alcohol use among heavy-drinking students aged 18-24 years at 1-, 3-, and 6-month follow-up intervals. A purely Web-based, 2-arm, parallel-group randomized controlled trial applying an ecological momentary assessment approach with 30 weekly measurements was conducted in the Netherlands (2010-2011). Participants were recruited offline and online. A total of 907 participants were randomized into the experimental condition (n=456) including the single-session and fully automated WDYD intervention, or into the control condition (n=451) including assessment only. Weekly alcohol consumption and frequency of binge drinking were the self-assessed outcome measures. Attrition rates of the 907 participants were 110 (12.1%), 130 (14.3%), and 162 (17.9%) at 1-, 3-, and 6-month follow-up intervals, respectively. Latent growth curve analyses according to the intention-to-treat principle revealed that participants in the experimental condition had significantly lower weekly alcohol consumption compared to participants in the control condition that was sustained at 3-month follow-up (intercept=-2.60, Padmin/rctview.asp?TC=2665 (Archived by WebCite at http://webcitation.org/6LuQVn12M).
Full Text Available Abstract Background There is a wealth of evidence regarding the detrimental impact of excessive alcohol consumption. In older populations excessive alcohol consumption is associated with increased risk of coronary heart disease, hypertension, stroke and a range of cancers. Alcohol consumption is also associated with an increased risk of falls, early onset of dementia and other cognitive deficits. Physiological changes that occur as part of the ageing process mean that older people experience alcohol related problems at lower consumption levels. There is a strong evidence base for the effectiveness of brief psychosocial interventions in reducing alcohol consumption in populations identified opportunistically in primary care settings. Stepped care interventions involve the delivery of more intensive interventions only to those in the population who fail to respond to less intensive interventions and provide a potentially resource efficient means of meeting the needs of this population. Methods/design The study design is a pragmatic prospective multi-centre two arm randomised controlled trial. The primary hypothesis is that stepped care interventions for older hazardous alcohol users reduce alcohol consumption compared with a minimal intervention at 12 months post randomisation. Potential participants are identified using the AUDIT questionnaire. Eligible and consenting participants are randomised with equal probability to either a minimal intervention or a three step treatment approach. The step treatment approach incorporates as step 1 behavioural change counselling, step 2 three sessions of motivational enhancement therapy and step 3 referral to specialist services. The primary outcome is measured using average standard drinks per day and secondary outcome measures include the Drinking Problems Index, health related quality of life and health utility. The study incorporates a comprehensive economic analysis to assess the relative cost

Alcohol use is a global public health problem, including as a risk factor for HIV infection, but few data are available on the epidemiology of alcohol use and alcohol use disorders (AUD) among young people in sub-Saharan Africa. We conducted a cross-sectional survey among 4 groups of young people aged 15-24 years old (secondary school students, college/university students, employees of local industries and casual labourers) in two regions (Kilimanjaro and Mwanza) of northern Tanzania. Using a multistage stratified random sampling strategy, we collected information on demographics, alcohol use, and behavioural factors. We screened severity of alcohol use using the Alcohol Use Disorder Identification Test (AUDIT) and estimated the quantity and frequency of alcohol consumption using the timeline-follow-back-calendar (TLFB) method. A total of 1954 young people were surveyed. The prevalence of reported alcohol use was higher among males (47-70% ever users and 20-45% current users) than females (24-54% ever users and 12-47% current users). Prevalence of use was substantially higher in Kilimanjaro than Mwanza region. In both regions, participants reported high exposure to alcohol advertisements, and wide alcohol availability. College students reported the highest prevalence of current alcohol use (45% among males; 26% among females) and of heavy episodic drinking (71% among males; 27% among females) followed by casual labourers. Males were more likely to have AUD (an AUDIT score ≥8) than females, with 11-28% of males screening positive for AUD. Alcohol use was associated with male gender, being in a relationship, greater disposable income, non-Muslim religion and a higher number of sexual partners. Alcohol use is a significant problem among young people in northern Tanzania. There is an urgent need to develop, pilot and deliver interventions to help young people delay initiation and reduce levels of harmful drinking, particularly among college students and casual

Alcohol and cannabis use have been implicated in aggression. Alcohol consumption is known to facilitate aggression, whereas a causal link between cannabis and aggression has not been clearly demonstrated. This study investigated the acute effects of alcohol and cannabis on subjective aggression in alcohol and cannabis users, respectively, following aggression exposure. Drug-free controls served as a reference. It was hypothesized that aggression exposure would increase subjective aggression in alcohol users during alcohol intoxication, whereas it was expected to decrease subjective aggression in cannabis users during cannabis intoxication. Heavy alcohol (n = 20) and regular cannabis users (n = 21), and controls (n = 20) were included in a mixed factorial study. Alcohol and cannabis users received single doses of alcohol and placebo or cannabis and placebo, respectively. Subjective aggression was assessed before and after aggression exposure consisting of administrations of the point-subtraction aggression paradigm (PSAP) and the single category implicit association test (SC-IAT). Testosterone and cortisol levels in response to alcohol/cannabis treatment and aggression exposure were recorded as secondary outcome measures. Subjective aggression significantly increased following aggression exposure in all groups while being sober. Alcohol intoxication increased subjective aggression whereas cannabis decreased the subjective aggression following aggression exposure. Aggressive responses during the PSAP increased following alcohol and decreased following cannabis relative to placebo. Changes in aggressive feeling or response were not correlated to the neuroendocrine response to treatments. It is concluded that alcohol facilitates feelings of aggression whereas cannabis diminishes aggressive feelings in heavy alcohol and regular cannabis users, respectively.

Drugs of abuse stimulate striatal dopamine release and activate reward pathways. This study examined the impact of alcohol and cannabis marketing on the reward circuit in alcohol and cannabis users while sober and intoxicated. It was predicted that alcohol and cannabis marketing would increase striatal activation when sober and that reward sensitivity would be less during alcohol and cannabis intoxication. Heavy alcohol (n = 20) and regular cannabis users (n = 21) participated in a mixed factorial study involving administration of alcohol and placebo in the alcohol group and cannabis and placebo in the cannabis group. Non-drug users (n = 20) served as between group reference. Brain activation after exposure to alcohol and cannabis marketing movies was measured using functional magnetic resonance imaging and compared between groups while sober and compared with placebo while intoxicated. Implicit alcohol and cannabis cognitions were assessed by means of a single-category implicit association test. Alcohol and cannabis marketing significantly increased striatal BOLD activation across all groups while sober. Striatal activation however decreased during intoxication with alcohol and cannabis. Implicit associations with cannabis marketing cues were significantly more positive in alcohol and cannabis users as compared with non-drug using controls. Public advertising of alcohol or cannabis use elicits striatal activation in the brain's reward circuit. Reduction of marketing would reduce brain exposure to reward cues that motivate substance use. Conversely, elevated dopamine levels protect against the reinforcing potential of marketing. © 2016 Society for the Study of Addiction.

el uso pesado de alcohol y los factores estudiados fueron analizadas por medio de regresión logística, considerando nivel de significancia de 5%. RESULTADOS: Del total de estudiantes, 4.286 (8,9% hicieron uso pesado de alcohol en el mes anterior a la entrevista. El análisis por regresión logística mostró asociación entre relaciones malas o regulares con padre (OR= 1,46 y madre (OR =1,61 y uso pesado de alcohol. Seguir una religión (OR=0,83 se mostró inversamente asociado a este tipo de consumo de alcohol. La práctica de deportes y el hecho de que la madre se perciba como liberal, no mostraron significancia en el modelo. Hubo mayor prevalencia del uso pesado de alcohol entre los estudiantes que trabajaban. CONCLUSIONES: Uniones familiares más coherentes y seguir una religión pueden prevenir el uso abusivo de alcohol entre estudiantes.OBJECTIVE: To evaluate the association between heavy use of alcohol among students and family, personal and social factors. METHODS: Cross-sectional study including public school students aged ten to 18 from 27 Brazilian capital cities in 2004. Data was collected using an anonymous, self-report questionnaire that was adapted from a World Health Organization instrument. A representative sample comprising 48,155 students was stratified by census tracts and clusters (schools. The associations between heavy alcohol use and the factors studied were analyzed using logistic regression at a 5% significance level. RESULTS: Of all students, 4,286 (8.9% reported heavy alcohol use in the month prior to the interview. The logistic regression analysis showed an association between fair or poor relationship with the father (OR = 1.46 and the mother (OR = 1.61 and heavy use of alcohol. Following a religion (OR = 0.83 was inversely associated with heavy alcohol consumption. Sports practice and mother perceived as a "liberal" person had no significance in the model. However, a higher prevalence of heavy use of alcohol was seen among working
Full Text Available Background: Structural imaging studies of cannabis users have found evidence of both cortical and subcortical volume reductions, especially in cannabinoid receptor-rich regions such as the hippocampus and amygdala. However, the findings have not been consistent. In the present study, we examined a sample of adult heavy cannabis users without other substance abuse to determine whether long-term use is associated with brain structural changes, especially in the subcortical regions.Method: We compared the gray matter volume of 14 long-term, heavy cannabis users with non-using controls. To provide robust findings, we conducted two separate studies using two different MRI techniques. Each study used the same sample of cannabis users and a different control group, respectively. Both control groups were independent of each other. First, whole-brain voxel-based morphometry (VBM was used to compare the cannabis users against 28 matched controls (HC1 group. Second, a volumetric analysis of subcortical regions was performed to assess differences between the cannabis users and a sample of 100 matched controls (HC2 group obtained from a local database of healthy volunteers.Results: The VBM study revealed that, compared to the control group HC1, the cannabis users did not show cortical differences nor smaller volume in any subcortical structure but showed a cluster (p < 0.001 of larger GM volume in the basal ganglia, involving the caudate, putamen, pallidum, and nucleus accumbens, bilaterally. The subcortical volumetric analysis revealed that, compared to the control group HC2, the cannabis users showed significantly larger volumes in the putamen (p = 0.001 and pallidum (p = 0.0015. Subtle trends, only significant at the uncorrected level, were also found in the caudate (p = 0.05 and nucleus accumbens (p = 0.047.Conclusions: This study does not support previous findings of hippocampal and/or amygdala structural changes in long-term, heavy cannabis users.

Background We know little about how social media alcohol marketing is utilized for alcohol promotion in different national contexts. There does not appear to be any academic work on online exposure to alcohol marketing via social media in India, and most of the limited research in Australia has focused on Facebook. Hence, the present study extends previous research by investigating alcohol promotion conducted on an under-researched form of social media (YouTube) in two contrasting geographic ...
Targeting young drinkers online: the effectiveness of a web-based brief alcohol intervention in reducing heavy drinking among college students: study protocol of a two-arm parallel group randomized controlled trial
Lemmers Lex ACJ
Full Text Available Abstract Background The prevalence of heavy drinking among college students and its associated health related consequences highlights an urgent need for alcohol prevention programs targeting 18 to 24 year olds. Nevertheless, current alcohol prevention programs in the Netherlands pay surprisingly little attention to the drinking patterns of this specific age group. The study described in this protocol will test the effectiveness of a web-based brief alcohol intervention that is aimed at reducing alcohol use among heavy drinking college students aged 18 to 24 years old. Methods/Design The effectiveness of the What Do You Drink web-based brief alcohol intervention will be tested among 908 heavy drinking college students in a two-arm parallel group randomized controlled trial. Participants will be allocated at random to either the experimental (N = 454: web-based brief alcohol intervention or control condition (N = 454: no intervention. The primary outcome measure will be the percentage of participants who drink within the normative limits of the Dutch National Health Council for low-risk drinking. These limits specify that, for heavy alcohol use, the mean consumption cannot exceed 14 or 21 glasses of standard alcohol units per week for females and males, respectively, while for binge drinking, the consumption cannot exceed five or more glasses of standard alcohol units on one drinking occasion at least once per week within one month and six months after the intervention. Reductions in mean weekly alcohol consumption and frequency of binge drinking are also primary outcome measures. Weekly Ecological Momentary Assessment will measure alcohol-related cognitions, that is, attitudes, self-efficacy, subjective norms and alcohol expectancies, which will be included as the secondary outcome measures. Discussion This study protocol describes the two-arm parallel group randomized controlled trial developed to evaluate the effectiveness of a web-based brief

Examines effect of alcohol use on the development of vibration disease among tunnellers, facemen and machine drill operators, miners exposed to dangerous amounts of vibration. Men were investigated using clinical-psychiatric and experimental psychological methods (memory tests, comprehension and scales of anxiety). Results of investigation demonstrated extent alcohol use affects time period during which vibration disease develops: occasional users developed disease in 12 years, moderate and heavy users in 9 1/2 years and chronic alcoholics in 7 1/2 years. With heavy use of alcohol, severity of vibration disease increased. Progressive tendency of disease continued among alcoholics even though contact with vibration ceased. In addition to vibration disease, frequency of psychopathological syndromes increased with alcohol use (occasional, moderate, heavy and chronic alcoholism). Increase in asthenic affective and psycho-organic syndromes paralleled degree of alcohol use from occasional to chronic alcoholism. With increased use, anxieties increase, ability to recall on memory tests declines, facility in switching from one task to another decreases. Results of study make clear need for better methods of preventing and treating drunkeness and alcoholism among miners in occupations subject to hazardous amounts of vibration. 10 refs.

A polymorphism in the promoter region of the monoamine oxidase A gene (MAOA) has been shown to alter the effect of persistent drinking and childhood maltreatment on the risk for violent and antisocial behaviors. These findings indicate that MAOA could contribute to inter-individual differences in stress resiliency. Recidivism in severe violent crimes was assessed after 8 years of nonincarcerated follow-up in a male sample of 174 impulsive Finnish alcoholic violent offenders, the majority of whom exhibited antisocial (ASPD) or borderline personality disorder (BPD) or both. We examined whether MAOA genotype alters the effects of heavy drinking and childhood physical abuse (CPA) on the risk for committing impulsive recidivistic violent crimes. Logistic regression analyses showed that both heavy drinking and CPA were significant independent predictors of recidivism in violent behavior (OR 5.2, p = 0.004 and OR 5.3, p = 0.003) among offenders having the high MAOA activity genotype (MAOA-H), but these predictors showed no effect among offenders carrying the low MAOA activity genotype (MAOA-L). Carriers of the MAOA-H allele have a high risk to commit severe recidivistic impulsive violent crimes after exposure to heavy drinking and CPA.

Criteria for alcohol use disorders (AUD) in the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) were intended to result in a similar prevalence of AUD as DSM-IV. We evaluated the prevalence of AUD using DSM-5 and DSM-IV criteria, and compared characteristics of patients who met criteria for: neither DSM-5 nor DSM-IV AUD, DSM-5 alone, DSM-IV alone, or both, among Veterans Administration (VA) outpatients in the Considering Healthier drinking Options In primary CarE (CHOICE) trial. VA primary care patients who reported frequent heavy drinking and enrolled in the CHOICE trial were interviewed at baseline using the DSM-IV Mini International Neuropsychiatric Interview for AUD, as well as questions about socio-demographics, mental health, alcohol craving, and substance use. We compared characteristics across 4 mutually exclusive groups based on DSM-5 and DSM-IV criteria. Of 304 participants, 13.8% met criteria for neither DSM-5 nor DSM-IV AUD; 12.8% met criteria for DSM-5 alone, and 73.0% met criteria for both DSM-IV and DSM-5. Only 1 patient (0.3%) met criteria for DSM-IV AUD alone. Patients meeting both DSM-5 and DSM-IV criteria had more negative drinking consequences, mental health symptoms and self-reported readiness to change compared with those meeting DSM-5 criteria alone or neither DSM-5 nor DSM-IV criteria. In this sample of primary care patients with frequent heavy drinking, DSM-5 identified 13% more patients with AUD than DSM-IV. This group had a lower mental health symptom burden and less self-reported readiness to change compared to those meeting criteria for both DSM-IV and DSM-5 AUD.

The tactical use of visuoperceptual content in marketing may encourage impulsive consumption of unhealthy products. In this study, the application of visuoperceptual content was compared in advertisements used by industries of tobacco, alcohol and food. The aim was to ascertain whether similarities exist in the strategies used as variables for the selection of commercial stimuli, such as color, position and size. Scion Image and Corel Draw Graphics Suite software were used to analyze the content of a non-probabilistic sample of advertising images (N = 150). Differences were identified in the use of the colors green (p = 0.04) and red (p = 0.01), but not in the use of the color blue (p = 0.64), suggesting that induction of feelings of pleasantness resulting from the use of the color blue may be associated with the advertising in the alcohol and tobacco industries. Regarding the position of the commercial stimuli, a predominance of the use of quadrants 'C' (p = 0.00) and 'D' (p = 0.01) was found in all three industries, indicating a similar use of areas perceived as being 'heavier'. As to the size, 78% of advertisements placed the commercial stimuli within a range of 0-25% of the total image. The results showed some similarities in the use of visuoperceptual content in advertisements for tobacco, alcohol and food, especially between tobacco and alcohol. The article offers a convergence analysis of these three industries altogether, providing additional subsidies for the formulation of protection policies. © The Author 2015.

The aim of this study was to investigate the following: (a) the effects of acute alcohol on delay discounting; (b) the effects of drinking status on delayed discounting; and (c) whether these effects differ according to reward type (alcohol vs. money). Heavy and light social alcohol users (n = 96) were randomized to receive either an acute dose of alcohol at 0.4 or 0.6 g/kg or placebo in a between-subjects, double-blind design. Delay discounting of alcohol and monetary rewards was measured using a hyperbolic model, with higher scores indicative of greater delay discounting. ANOVA of discount scores indicated a main effect of reward type, where all participants had higher discount scores for alcohol versus money rewards. A main effect of drinking status was also observed, where heavier drinkers had higher discount scores compared with lighter drinkers. We did not observe a main effect of acute alcohol use on delay discounting or the hypothesized interactions between acute alcohol use and drinking status with reward type. Our data suggest that heavier drinkers discount the value of delayed rewards more steeply than lighter drinkers. Delay discounting may therefore be a promising marker of heavy alcohol consumption in social drinkers. Copyright © 2017 John Wiley & Sons, Ltd.

Alcohol addiction is associated with high psychiatric comorbidity. Objective stratification of patients is necessary to optimize care and improve prognosis. The present study is designed to gain insights into this challenge by addressing the following objectives: a) to estimate the prevalence of psychiatric comorbidities in a sample of outpatients seeking treatment for alcohol use disorder, b) to describe the existence of gender differences and c) to validate 2-acyl-glycerols as biomarkers of alcohol use disorder and/or psychiatric comorbidity. One hundred and sixty-two patients were recruited and evaluated with the semi-structured interview PRISM. The presence of psychopathology was associated with a greater number of criteria for alcohol abuse and dependence according to DSM-IV-TR. We found gender differences in psychiatric comorbidity, e.g., mood disorder, as well as in comorbid substance use disorders. The prevalence of lifetime psychiatric comorbidity was 68.5%, with mood disorders the most frequent (37%), followed by attention deficit disorder (24.7%) and anxiety disorders (17.9%). Substance-induced disorders were more frequent in mood and psychotic disorders, whereas the primary disorders were more prevalent in patients with comorbid anxiety disorders. We found that 2-acyl-glycerols were significantly decreased in comorbid anxiety disorders in alcohol dependent patients in the last year, which makes them a potential biomarker for this psychopathological condition.

A recent study suggested that college students who combined alcohol and energy drinks were more likely than students who consumed only alcohol to drive when their blood alcohol concentration (BAC) was higher than the .08% limit and to choose to drive despite knowing they had too much alcohol to drive safely. This study sought to replicate those findings with a larger sample while also exploring additional variables related to impaired driving. College students (N = 549) completed an anonymous online survey to assess differences in drinking and driving-related behaviors between alcohol-only users (n = 281) and combined alcohol-energy drink users (n = 268). Combined users were more likely than alcohol-only users to choose to (a) drive when they perceived they were over the .08% BAC limit (35.0% vs. 18.1%, p drinks consumed, number of days drinking, number of days drunk, number of heavy episodic drinking episodes, greatest number of drinks on one occasion, and average hours of consumption. Combined use of alcohol and energy drinks may place drinkers at greater risk when compared with those who consume only alcohol. College students in this sample who combined alcohol and energy drinks were more likely to participate in high-risk driving behaviors than those who consumed only alcohol.
Full Text Available Abstract Background To determine the patterns of alcohol use among households in Trinidad and Tobago (T&T and to estimate the association between alcohol use and negative psychological, social, or physical events experienced by the household. Methods A convenience sample of 1837 households across T&T. We identified bivariate correlates of alcohol use, and heavy episodic drinking using chi-square and t-test analyses and used multivariable logistic regression to estimate adjusted associations between household alcohol use and experiences within the past 12 months adjusted for sociodemographic covariates. Results One thousand five hundred two households had complete data for all variables (82% response rate. Nearly two thirds (64% of households included alcohol users; 57% of household that consumed alcohol also reported heavy episodic drinking. Households that reported alcohol consumption were significantly more likely to report illnesses within the households, relationship problems, and behavioral and antisocial problems with children. Among households where a member was employed, those who consumed alcohol were nearly twice as likely (OR = 1.98; 95% confidence interval (CI 1.03, 3.82 to have a household member call in sick to work and 2.9 times as likely (OR = 2.9; CI 1.19, 7.04 to have a household member suffer work related problems compared with households who reported not consuming alcohol. Conclusions Approximately two thirds of households in T&T reported using alcohol. These households were more likely to report psychological, physical, and social problems. These findings would support efforts to enforce current policies, laws, and regulations as well as new strategies to reduce the impact of harmful alcohol consumption on households in T&T.

The purpose of this study was to examine neurological impairment in combination with information-motivation-behavioral skills (IMB) variables. The study tests the role of IMB variables as mediators of antecedent variables of demographics, life stress, social support, and neurological impairment with outcome measures of HIV preventive and risk behaviors in a sample of HIV-positive, alcohol-using adults (n = 250) with a history of alcohol abuse/dependence. Neurological impairment was measured with the Color Trails Test (CTT). Average performance on the CTT by the sample was substantially worse than established norms. In a directional latent variable model, neurological impairment directly predicted lower transmission knowledge scores and poorer performance on an observational condom skills assessment. Greater neurological impairment was significantly associated with greater age. Future interventions geared toward HIV+ adults who use alcohol should take into consideration HIV-related and age-related neurological functioning which may impede the facilitation of safe sex behaviors.

Full Text Available Assistance to users of alcohol and other drugs in Brazil has undergone several transformations owing to historical, social, and political phenomena. In 2009, the Ministry of Health created the ‘Street Clinic’ in order to reduce harm to the homeless and the population vulnerable to use of alcohol or other drugs. The aim of this study was to describe and analyze the experience at a ‘Street Clinic’ from the perspective of the professionals who compose the service team in a municipality located in the metropolitan region of Recife, Pernanbuco state. This is a qualitative study with data collected through semi-structured interviews with five professionals and submitted to qualitative analysis. The content of the interviews explained the dynamic character of the reality experienced by professionals and the time of implementation and consolidation of this service in the city, characterizing the objectives, clientele, user demand, and systematization of actions and difficulties in delivering the service. It was possible to identify similarities between the experiences of the research participants and what is recommended by the Ministry of Health, as well as similarities with other services described in the literature. Furthermore, the data revealed the day to day challenges experienced by the professionals expressed mainly in the difficulties reported in the interviews. The study provided a good basis for the implementation of other Street Clinic teams and the training of professionals, including occupational therapists, to work in this field.
Full Text Available Background/Aims: Heavy ethanol consumption is a risk factor for hypertension and prompts organ damage. There is no information regarding the impact of long-term heavy ethanol consumption on kidney structure and function linking to their hypertensive effects nor the repercussions after withdrawal. Methods: Rats were exposed to ethanol for 24 weeks and, afterwards, a group was assigned to withdrawal for 8 weeks. Blood pressure (BP was measured and serum biochemical parameters were quantified. Glomerular volume density, areal density of glomerular tuft and renal corpuscles were determined. Angiotensin II type 1 receptor (AT1R protein expression was evaluated. Results: Twenty-four weeks of ethanol consumption causes atrophy of renal corpuscles and glomeruli and reduces the volume of glomeruli. Glomerular changes induced by ethanol consumption were still evident after withdrawal. Renal AT1R levels were increased in ethanol-treated rats and returned to control levels during withdrawal. Ethanol consumption also induced an increase in BP, uric acid and albumin levels. Upon withdrawal, systolic and mean arterial pressures decreased, but were still higher than in controls rats. Conclusion: Ethanol consumption induces changes in glomerular morphology associated with increased BP and AT1R expression. Long-term withdrawal was inefficient to restore the structural integrity of renal corpuscles and in lowering systolic pressure.

Growing evidence suggests that the consumption of caffeinated alcoholic beverages (CAB) may be riskier than alcohol alone. Efforts to identify patterns of CAB use and the correlates of such drinking patterns could further our conceptualization of and intervention for this health issue. Consequently, the current study aimed to (1) identify distinct classes of CAB users, (2) examine differences between classes on measures of alcohol and caffeine problems, and (3) compare distinct classes of CAB users on caffeine and alcohol outcome expectancies. Participants were 583 (31% men) undergraduate students from a psychology research pool. Latent profile analysis models were derived using four indicators: CAB use quantity, CAB use frequency, alcohol use quantity, and alcohol use frequency. Finding revealed four classes of drinkers: High Alcohol/High CAB (6.00%), High Alcohol/Moderate CAB (5.15%), High Alcohol/Low CAB (22.99%), and Low Alcohol/Low CAB (65.87%). The Low Alcohol/Low CAB class reported the lowest relative levels of caffeine dependence symptoms, caffeine withdrawal, alcohol use problems, and heavy episodic drinking frequency. Further, results indicated differential expectancy endorsement based on use profiles. CAB users in the High Alcohol/Low CAB class endorsed more positive alcohol expectancies than the Low Alcohol/Low CAB group. Those in the High Alcohol/High CAB class endorsed stronger withdrawal symptom caffeine expectancies than all other classes. Inclusion of substance-specific expectancies into larger theoretical frameworks in future work of CAB use may be beneficial. Findings may inform intervention efforts for those at greatest risk related to CAB consumption. © 2013.

Full Text Available Characterizing the effects of alcohol and marijuana use on adolescent brain development is important for understanding potential alterations in neurodevelopment. Several cross sectional studies have identified group differences in white matter integrity after initiation of heavy alcohol and marijuana use, however none have explored white matter trajectories in adolescents pre- and post initiation of use, particularly for marijuana users. This study followed 16 adolescents with minimal alcohol and marijuana use at ages 16–18 over three years. At follow-up, teens were 19–22 years old; half of the participants initiated heavy alcohol use and half initiated heavy alcohol and marijuana use. Repeated-measures ANOVA revealed 20 clusters in association and projection fibers tracts (p < 0.01 in which a group by time interaction was found. Most consistently, white matter integrity (i.e., fractional anisotropy decreased for those who initiated both heavy alcohol and marijuana use over the follow-up interval. No effect of time or change in white matter integrity was seen for those who initiated alcohol use only in the majority of clusters. In most regions, at the baseline time point, teens who would later initiate both alcohol and marijuana use demonstrated white matter integrity greater than or equal to teens that initiated alcohol use only. Findings suggest poorer tissue integrity associated with combined initiation of heavy alcohol and marijuana use in late adolescence. While pre-existing differences may also be related to likelihood of substance use, the present data suggest an effect on tissue integrity for these teens transitioning to combined alcohol and marijuana use in later adolescence.

There is clear evidence of the detrimental impact of hazardous alcohol consumption on the physical and mental health of the population. Estimates suggest that hazardous alcohol consumption annually accounts for 150,000 hospital admissions and between 15,000 and 22,000 deaths in the UK. In the older population, hazardous alcohol consumption is associated with a wide range of physical, psychological and social problems. There is evidence of an association between increased alcohol consumption and increased risk of coronary heart disease, hypertension and haemorrhagic and ischaemic stroke, increased rates of alcohol-related liver disease and increased risk of a range of cancers. Alcohol is identified as one of the three main risk factors for falls. Excessive alcohol consumption in older age can also contribute to the onset of dementia and other age-related cognitive deficits and is implicated in one-third of all suicides in the older population. To compare the clinical effectiveness and cost-effectiveness of a stepped care intervention against a minimal intervention in the treatment of older hazardous alcohol users in primary care. A multicentre, pragmatic, two-armed randomised controlled trial with an economic evaluation. General practices in primary care in England and Scotland between April 2008 and October 2010. Adults aged ≥ 55 years scoring ≥ 8 on the Alcohol Use Disorders Identification Test (10-item) (AUDIT) were eligible. In total, 529 patients were randomised in the study. The minimal intervention group received a 5-minute brief advice intervention with the practice or research nurse involving feedback of the screening results and discussion regarding the health consequences of continued hazardous alcohol consumption. Those in the stepped care arm initially received a 20-minute session of behavioural change counselling, with referral to step 2 (motivational enhancement therapy) and step 3 (local specialist alcohol services) if indicated.

The study investigated, through a literature review, how the research community has addressed the difficulties experiences by the teams in front of new prescriptions for the treatment of alcohol and drug users in Centers of Psyco-social Attention and discusses the relevance of the conceptual and methodological references of Ergonomics for understand and transform work situations. Such studies tend to do an analysis that does not account for variability present in both the workers and work organization and prioritize the analysis of final results of the, disqualifying local inventions due to tasks imposed by policy guidelines. It is estimated that the Ergonomics, considering the diversity of training, learning and experience, contributes to the implementation of media to promote the continued development of competences that can meet the demands of production and expands knowledge about the problems experienced and the possibilities of overcoming them.

The cannabinoid-1 receptor (CB1R) agonist Δ9-tetrahydrocannabinol (THC), the main psychoactive constituent of cannabis, adversely effects working memory performance in humans. The α2A-adrenoceptor (AR) agonist guanfacine improves working memory performance in humans. The authors aimed to determine the effects of short-term (6 days) treatment with guanfacine on adverse cognitive effects produced by THC. Employing a double-blind, placebo-controlled crossover design, the cognitive, subjective, and cardiovascular effects produced by oral THC (20 mg) administration were determined twice in the same cannabis users: once after treatment with placebo and once after treatment with guanfacine (3 mg/day). Compared with performance at baseline, THC negatively affected accuracy on spatial working memory trials while participants were maintained on placebo (p=0.012) but not guanfacine (p=0.497); compared with placebo, accuracy was significantly (p=0.003, Cohen's d=-0.640) improved while individuals were treated with guanfacine. Similarly, compared with baseline, THC increased omission errors on an attentional task while participants were maintained on placebo (p=0.017) but not on guanfacine (p=0.709); compared with placebo, there were significantly (p=0.034, Cohen's d=0.838) fewer omissions while individuals were maintained on guanfacine. Although THC increased visual analog scores of subjective effects and heart rate, these increases were similar during treatment with placebo and guanfacine. THC did not significantly affect performance of a recognition memory task or blood pressure while individuals were maintained on either treatment. Although preliminary, these results suggest that guanfacine warrants further testing as a potential treatment for cannabis-induced cognitive deficits.

The aim of this study was to analyse in women the association between four dimensions of gender identity, heavy episodic drinking (HED) and alcohol use disorders (AUD), taking into account age, personality, psychiatric co-morbidity and level of education. An initial screening of alcohol consumption was followed by a structured psychiatric interview in a sample of women drawn from the Gothenburg population and women attending primary care, maternity and hospital services (n = 930). Gender identity was assessed using the Masculinity-Femininity Questionnaire (M/F-Q) (items grouped into four dimensions: leadership, caring, self-assertiveness and emotionality). The Karolinska Scale of Personality was administered. Clinical psychiatric diagnoses according to DSM were made in face-to-face interviews. HED was defined as consumption of at least 60 g of ethanol on a single day at least once a month. Women who scored low on the leadership dimension were twice as likely to have AUD [age-adjusted odds1.98 (95% confidence interval 1.30-3.01)] compared to those with medium scores. These odds ratios were significant after adjustment for personality [2.21 (1.35-3.63)], psychiatric disorders [2.09 (1.25-3.47)] and level of education [1.95 (1.17-3.26)]. Low scores on the leadership dimension were associated with HED [1.55 (0.98-2.44)] after adjustment for age, personality, psychiatric disorders and level of education. High scores on leadership were not significantly associated with AUD or HED after these adjustments. The odds ratios for those who scored low on caring were non-significant throughout the analyses of associations with both AUD and HED. A similar pattern was found for the self-assertiveness dimension. Low emotionality was associated with decreased odds for AUD [0.42 (0.25-0.70)] and HED [0.66 (0.44-0.99)], and increased odds for AUD [2.14 (1.38-3.31)] and HED [2.33 (1.58-3.44)], after adjusting for age. These associations became non-significant after adjustment for

Cognitive impairment has been associated with excessive alcohol use, but its neural basis is poorly understood. Chronic excessive alcohol use in adolescence may lead to neuronal loss and volumetric changes in the brain. Our objective was to compare the grey matter volumes of heavy- and light-drinking adolescents. This was a longitudinal study: heavy-drinking adolescents without an alcohol use disorder and their light-drinking controls were followed-up for 10 years using questionnaires at three time-points. Magnetic resonance imaging was conducted at the last time-point. The area near Kuopio University Hospital, Finland. The 62 participants were aged 22-28 years and included 35 alcohol users and 27 controls who had been followed-up for approximately 10 years. Alcohol use was measured by the Alcohol Use Disorders Identification Test (AUDIT)-C at three time-points during 10 years. Participants were selected based on their AUDIT-C score. Magnetic resonance imaging was conducted at the last time-point. Grey matter volume was determined and compared between heavy- and light-drinking groups using voxel-based morphometry on three-dimensional T1-weighted magnetic resonance images using predefined regions of interest and a threshold of P Grey matter volumes were significantly smaller among heavy-drinking participants in the bilateral anterior cingulate cortex, right orbitofrontal and frontopolar cortex, right superior temporal gyrus and right insular cortex compared to the control group (P grey matter. Moreover, the structural changes detected in the insula of alcohol users may reflect a reduced sensitivity to alcohol's negative subjective effects. © 2016 Society for the Study of Addiction.

Given the dynamic fluctuating nature of alcohol use among emerging adults (Del Boca, Darkes, Greenbaum, & Goldman, 2004), patterns of alcohol use were modeled across 70 days in an intensive repeated-measures diary design. Two hundred first-year college students provided 10 weekly reports of their daily alcohol consumption via computer-assisted telephone interviews. Multi-level models demonstrated large within-person variability across days in drinks consumed, binge drinking, and days exceeding self-reported limits for stumbling around and passing out; these outcome variables were predicted by weekdays vs. weekend days (within-person) and gender, age of drinking initiation, fraternity/sorority membership, and alcohol motivations (between-persons). Repeated measurement of alternate indicators of alcohol use permits the examination of novel and important questions about alcohol use and abuse particularly in young adult and other erratically drinking populations.

Background Ecstasy use is prevalent among young people and often co-occurs with other drug use, but little is known about the past 12-month and lifetime psychiatric comorbidity and specific additional drug abuse among young adult ecstasy users in the general population. To provide this information, we compared current ecstasy users to former users, other illicit drug users, and non-illicit drug users. Method Data were gathered in a face-to-face survey of the United States conducted in the 2001–2002 (NESARC). Participants were household and group quarters residents aged 18–29 years (n = 8666). We measured current ecstasy use defined as any use in the past year; former ecstasy use as use prior to the past year only; other lifetime drug use included any drug other than ecstasy; lifetime non-illicit drug use as no illicit drug use. Associations were determined for nine other classes of illicit drugs, eight personality disorders, and seven mood and anxiety disorders. Results Of current ecstasy users, 44% used >3 other classes of illicit drugs in the past year, compared to 1.6% of non-ecstasy drug users. Current ecstasy use was associated with current anxiety (OR = 3.7), specifically panic disorder (OR = 7.7) and specific phobia (OR = 4.1), also alcohol abuse (OR = 21.6) and dependence (OR = 4.1) and any personality disorder (OR = 5.1) compared to non-illicit drug users. Conclusions Results indicate important differences in comorbidities of current and former ecstasy users compared to other drug users and lifetime non-illicit drug users that may affect phenotype definitions and etiologic studies. Ecstasy use may represent a distinct population of drug users for which unique treatments may be necessary. PMID:18524499

There has been a significant increase in the availability of online programs for alcohol problems. A systematic review of the research evidence underpinning these programs is timely. Our objective was to review the efficacy of online interventions for alcohol misuse. Systematic searches of Medline, PsycINFO, Web of Science, and Scopus were conducted for English abstracts (excluding dissertations) published from 1998 onward. Search terms were: (1) Internet, Web*; (2) online, computer*; (3) alcohol*; and (4) E\\effect*, trial*, random* (where * denotes a wildcard). Forward and backward searches from identified papers were also conducted. Articles were included if (1) the primary intervention was delivered and accessed via the Internet, (2) the intervention focused on moderating or stopping alcohol consumption, and (3) the study was a randomized controlled trial of an alcohol-related screen, assessment, or intervention. The literature search initially yielded 31 randomized controlled trials (RCTs), 17 of which met inclusion criteria. Of these 17 studies, 12 (70.6%) were conducted with university students, and 11 (64.7%) specifically focused on at-risk, heavy, or binge drinkers. Sample sizes ranged from 40 to 3216 (median 261), with 12 (70.6%) studies predominantly involving brief personalized feedback interventions. Using published data, effect sizes could be extracted from 8 of the 17 studies. In relation to alcohol units per week or month and based on 5 RCTs where a measure of alcohol units per week or month could be extracted, differential effect sizes to posttreatment ranged from 0.02 to 0.81 (mean 0.42, median 0.54). Pre-post effect sizes for brief personalized feedback interventions ranged from 0.02 to 0.81, and in 2 multi-session modularized interventions, a pre-post effect size of 0.56 was obtained in both. Pre-post differential effect sizes for peak blood alcohol concentrations (BAC) ranged from 0.22 to 0.88, with a mean effect size of 0.66. The available

To evaluate the relationship between alcohol consumption and the risk of acute exacerbation of COPD (AECOPD). We conducted a secondary analysis of data previously collected in a large, multicenter trial of daily azithromycin in COPD. To analyze the relationship between amount of baseline self-reported alcohol consumption in the past 12 months and subsequent AECOPD, we categorized the subjects as minimal (alcohol users (>60 drinks/month). The primary outcome was time to first AECOPD and the secondary outcome was AECOPD rate during the 1-year study period. Of the 1,142 enrolled participants, 1,082 completed baseline alcohol questionnaires and were included in this analysis. Six hundred and forty-five participants reported minimal alcohol intake, 363 reported light-to-moderate intake, and 74 reported heavy intake. There were no statistically significant differences in median time to first AECOPD among minimal (195 days), light-to-moderate (241 days), and heavy drinkers (288 days) (P=0.11). The mean crude rate of AECOPD did not significantly differ between minimal (1.62 events per year) and light-to-moderate (1.44 events per year) (P=0.095), or heavy drinkers (1.68 events per year) (P=0.796). There were no significant differences in hazard ratios for AECOPD after adjustment for multiple covariates. Among persons with COPD at high risk of exacerbation, we found no significant relationship between self-reported baseline alcohol intake and subsequent exacerbations. The number of patients reporting heavy alcohol intake was small and further study is needed to determine the effect of heavy alcohol intake on AECOPD risk.

Individuals affected by severe Borderline Personality Disorder (BPD) are often heavy users of Mental Health Services (MHS). Short-term treatments currently used in BPD therapy are useful to target disruptive behaviors but they are less effective in reducing heavy MHS use. Therefore, alternative short-term treatments, less complex than long-term psychodynamic psychotherapies but specifically oriented to BPD core problems, need to be developed to reduce MHS overuse. This study aimed to evaluate the efficacy of adding Sequential Brief Adlerian Psychodynamic Psychotherapy (SB-APP) to Supervised Team Management (STM) in BPD treatment compared to STM alone in a naturalistic group of heavy MHS users with BPD. Effectiveness was evaluated 6 times along a two-year follow-up. Thirty-five outpatients who met inclusion criteria were randomly assigned to two treatment groups (STM = 17; SB-APP = 18) and then compared. Clinical Global Impression (CGI) and CGI-modified (CGI-M) for BPD, Global Assessment of Functioning (GAF), State-Trait Anger Expression Inventory (STAXI), and Symptom Checklist-90 Revised (SCL-90-R) were administered at T1, T3, T6, T12, T18 and T24. At T12 the Working Alliance Inventory-Short Form (WAI-S) was also completed. At the one-year follow-up, SB-APP group did not receive any additional individual psychological support. MHS team was specifically trained in BPD treatment and had regular supervisions. All patients improved on CGI, GAF, and STAXI scores after 6 and 12 months, independently of treatment received. SB-APP group showed better outcome on impulsivity, suicide attempts, chronic feelings of emptiness, and disturbed relationships. We found a good stabilization at the one year follow-up, even after the interruption of brief psychotherapy in the SB-APP group. Although STM for BPD applied to heavy MHS users was effective in reducing symptoms and improving their global functioning, adding a time-limited and focused psychotherapy was found to achieve a

Background There is limited evidence for an association between the pattern of lifetime alcohol use and cause-specific risk of death. Methods Multivariable hazard ratios were estimated for different causes of death according to patterns of lifetime alcohol consumption using a competing risks approach: 111 953 men and 268 442 women from eight countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) study were included. Self-reported alcohol consumption at ages 20, 30, 40 or 50 years and at enrolment were used for the analysis; 26 411 deaths were observed during an average of 12.6 years of follow-up. Results The association between lifetime alcohol use and death from cardiovascular diseases was different from the association seen for alcohol-related cancers, digestive, respiratory, external and other causes. Heavy users (>5 drinks/day for men and >2.5 drinks/day for women), regardless of time of cessation, had a 2- to 5-times higher risk of dying due to alcohol-related cancers, compared with subjects with lifetime light use (≤1 and ≤0.5 drink/week for men and women, respectively). Compared with lifetime light users, men who used <5 drinks/day throughout their lifetime had a 24% lower cardiovascular disease mortality (95% confidence interval 2-41). The risk of death from coronary heart disease was also found to be 34–46% lower among women who were moderate to occasionally heavy alcohol users compared with light users. However, this relationship was only evident among men and women who had no chronic disease at enrolment. Conclusions Limiting alcohol use throughout life is associated with a lower risk of death, largely due to cardiovascular disease but also other causes. However, the potential health benefits of alcohol use are difficult to establish due to the possibility of selection bias and competing risks related to diseases occurring later in life.

The magnitude and consequences of unrecorded alcohol consumption, defined as home brewed or clandestinely produced illicit liquor or surrogate alcoholic beverage has been little investigated in India. A significant portion of all alcohol consumed globally is unrecorded, therefore these consumers constitute a significant population. Sikkim, a province in Northeast India, lies in the foothills of the Himalayas. Unrecorded alcohol use is traditionally prevalent, with more than ten types available. This study investigated correlates of problematic unrecorded alcohol consumption in rural and urban communities of Sikkim. A cross-sectional, community-based pilot survey was conducted. Intensive case-finding recruited current heavy users (at least 3 days/week) of unrecorded alcohol of either sex above 16 years of age. On enrolment, participants responded to a socio-demographic instrument including 12 questions on their pattern of alcohol consumption and a 4-item CAGE questionnaire. Alcohol problems exist significantly among the young adult population. Although consumption of unrecorded alcohol is traditional in Sikkim, it has emerged as an important public health problem, with alarmingly high rates of problematic consumption. This is also expected to have significant economic costs. Therefore, prevention and treatment measures are an urgent need as well as policy decisions on production and sales of unrecorded alcohol.

Each year, 5000-6000 individuals undergo orthotopic liver transplantation (OLT) in the United States, and of these, nearly 18% have alcoholic liver disease. Relapse to alcohol occurs in more than 40% of patients with OLT for alcoholic liver disease. We sought to identify factors that predict relapse to alcohol or medication nonadherence following OLT in patients with alcoholic liver disease and to review what randomized clinical interventions have addressed these factors following OLT. Our hypothesis was that there would be factors before and after OLT that predict relapse to alcohol following OLT, and that these, if targeted, might improve sobriety and associated outcomes of adherence with medications and appointments. We performed a review (focusing on articles published since 2004) with PubMed and MEDLINE searches using the following search terms: liver transplantation, recidivism, alcohol relapse, and predictors of alcohol relapse. We supplemented the online searches with manual reviews of article reference lists and selected relevant articles for further review by author consensus. In largely white populations, prospective studies document that shorter length of pretransplantation sobriety is a significant predictor of time to first drink and time to binge use. Presence of psychiatric comorbidity, high score on standardized High-risk Alcoholism Relapse Scale, and diagnosis of Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) alcohol dependence are predictive of posttransplantation alcohol relapse. Pretransplantation alcohol use history variables (e.g., family history of alcoholism) reliably discriminate between complete abstainers and those who drink, while medical and psychosocial characteristics at early post-liver transplantation period (e.g., more bodily pain) maximally discriminate patterns of alcohol use. Alcoholic individuals with early-onset, rapidly accelerating moderate use and early-onset, continuously increasing heavy use have

Full Text Available Abstract Background Alcohol misuse is more prevalent among military populations. Association between PTSD and heavy drinking have been reported in many studies. Most of the studies on alcohol use among military personnel are from US and UK. Aim of this study is to describe alcohol consumption patterns among military personnel in Sri Lanka, a country where the alcohol consumption among the general population are very different to that in US and UK. Methods Cross sectional study consisting of representative samples of Sri Lanka Navy Special Forces and regular forces deployed in combat areas continuously during a one year period was carried out. Data was collected using a self report questionnaire. Alcohol Use Disorder Identification Test (AUDIT was used to assess alcohol consumption. Results Sample consisted of 259 Special Forces and 412 regular navy personnel. The median AUDIT score was 2.0 (interquartile range 6.0. Prevalence of current drinking was 71.2 %. Of the current users 54.81 % were infrequent users (frequency ≤ once a month while 37.87 % of users consumed 2–4 times a month. Prevalence of hazardous drinking (AUDIT ≥ 8 was 16.69 % and binge drinking 14.01 %. Five (0.75 % had AUDIT total ≥20. There was no significant difference between Special Forces and regular forces in hazardous drinking or binge drinking. Total AUDIT score ≥16 were associated with difficulty performing work. Conclusions High rates of hazardous drinking and binge drinking described among military personnel in US and UK were not seen among SLN personnel deployed in combat areas. This finding contrasts with previously reported association between combat exposure and hazardous alcohol use among military personnel. Alcohol use among military personnel may be significantly influenced by alcohol consumption patterns among the general population, access to alcohol and attitudes about alcohol use. Similar to findings from other countries, heavy

Most alcoholics experience periods of voluntary alcohol abstinence or imposed alcohol deprivation followed by a return to alcohol drinking. This study examined whether varenicline (VAR) reduces alcohol intake during a return to drinking after periods of alcohol deprivation in rats selectively bred for high alcohol drinking (the alcohol preferring or "P" rats). Alcohol-experienced P rats were given 24-hour access to food and water and scheduled access to alcohol (15% and 30% v/v) for 2 h/d. After 4 weeks, rats were deprived of alcohol for 2 weeks, followed by reaccess to alcohol for 2 weeks, and this pattern was repeated for a total of 3 cycles. Rats were fed either vehicle (VEH) or VAR, in doses of 0.5, 1.0, or 2.0 mg/kg BW, at 1 hour prior to onset of the daily alcohol reaccess period for the first 5 days of each of the 3 alcohol reaccess cycles. Low-dose VAR (0.5 mg/kg BW) reduced alcohol intake during the 5 days of drug treatment in alcohol reaccess cycles 1 and 2. Higher doses of VAR (1.0 mg/kg BW and 2.0 mg/kg BW) reduced alcohol intake during the 5 days of treatment in all 3 alcohol reaccess cycles. The decrease in alcohol intake disappeared with termination of VAR treatment in all alcohol reaccess cycles. The results demonstrate that VAR decreases alcohol intake during multiple cycles of alcohol reaccess following alcohol deprivation in rats and suggests that it may prevent a return to heavy alcohol drinking during a lapse from alcohol abstinence in humans with alcohol use disorder.

Alcohol and drug use is a serious health problem for many indigenous populations across Canada, including Inuit. The literature on substance use in these populations is too sparse to devise public health interventions. The present article portrays alcohol and drug use among Inuit living in Nunavik (Northern Quebec) between the 1990s and 2000s, and identifies socio-demographic characteristics related to substance use. The Santé Québec Health Survey (1992) and the Nunavik Inuit Health Survey Qanuippitaa (2004) served as databases for this empirical work. Statistical comparisons were made of substance use variables in the 2 samples. Proportions were compared by chi-square tests (p≤0.05) with benchmarking of statistics for all of Quebec and, when available, all of Canada. Alcohol and drug use among Inuit increased significantly between 1992 and 2004, particularly among young adults. Alcohol users consumed significantly more alcohol per drinking episode than other Canadians in both time periods. Considerable cannabis use was widespread. In 2004, no significant differences in frequencies of heavy drinking episodes were observed by gender, with 60% of drug users consuming alcohol on a regular basis. As in other populations from North America, this study profiles the increase in substance use among Inuit from Nunavik in the first part of the last 20 years. We observed distinct substance use patterns among them in comparison to other Canadians. Such findings, if replicated in the coming years, emphasize the need for major, culturally-relevant public health interventions in this population.

Problematic alcohol use and increased sensitivity postoperatively in adult weight loss surgery patients heightens concerns. No data have characterized these behaviors in adolescents-a gap, given adolescent alcohol use and heavy drinking are public health concerns. To examine alcohol use behavior in adolescents who underwent weight loss surgery across the first two post-operative years in comparison to nonsurgical adolescents. Five academic medical centers. Utilizing a prospective controlled design, adolescents undergoing weight loss surgery (n = 242) and nonsurgical adolescents with severe obesity (n = 83) completed the Alcohol Use Disorders Test. Analyses included 216 surgical (M age = 17.1 ± 1.5, M BMI = 52.9 ± 9.3, 91.8% female, 67.6% white) and 79 nonsurgical participants (M age = 16.2 ± 1.4, M BMI = 46.9 ± 6.1, 82.3% female, 53.2% white), with baseline data and at 12 or 24 months postoperatively. The majority reported never consuming alcohol within the year before surgery (surgical, 92%; nonsurgical, 91%) or by 24 months (surgical, 71%; nonsurgical, 74%), when alcohol use disorder approached 9%. Among alcohol users at 24 months (n = 52 surgical, 17 nonsurgical), 35% surgical and 29% nonsurgical consumed 3+drinks on a typical drinking day; 42% surgical and 35% nonsurgical consumed 6+drinks on at least 1 occasion. For the surgical group, alcohol use changed as a function of older age (odds ratio [OR] = 2.47, P = .01) and lower body mass index (OR = .94, PBariatric Surgery. Published by Elsevier Inc.

Full Text Available Atherosclerosis is manifested as coronary artery disease (CAD, ischemic stroke and peripheral vascular disease. Moderate alcohol consumption has been associated with reduction of CAD complications. Apparently, red wine offers more benefits than any other kind of drinks, probably due to flavonoids. Alcohol alters lipoproteins and the coagulation system. The flavonoids induce vascular relaxation by mechanisms that are both dependent and independent of nitric oxide, inhibits many of the cellular reactions associated with atherosclerosis and inflammation, such as endothelial expression of vascular adhesion molecules and release of cytokines from polymorphonuclear leukocytes. Hypertension is also influenced by the alcohol intake. Thus, heavy alcohol intake is almost always associated with systemic hypertension, and hence shall be avoided. In individuals that ingest excess alcohol, there is higher risk of coronary occlusion, arrhythmias, hepatic cirrhosis, upper gastrointestinal cancers, fetal alcohol syndrome, murders, sex crimes, traffic and industrial accidents, robberies, and psychosis. Alcohol is no treatment for atherosclerosis; but it doesn't need to be prohibited for everyone. Thus moderate amounts of alcohol (1-2 drinks/day, especially red wine, may be allowed for those at risk for atherosclerosis complications.
This paper is part of an ongoing mixed methods project about untreated heavy alcohol consumption amongst adult Danes. It is based upon 21 in-depth qualitative interviews with convicted drink drivers. All interviewees were contacted while attending mandatory courses in “Alcohol and Traffic safety...... on the interviewee’s risk behaviour, especially in relation to driving. The interviewees are first divided into 1) a group of young “edgeworkers” with pronounced general risk behaviour, 2) a group of middle-aged “post-edgeworkers”, most with criminal records, and 3) a group of middle-aged and older heavy consumers...

A novel SAITS alcoholism model on networks is introduced, in which alcoholics are divided into light problem alcoholics and heavy problem alcoholics. Susceptible individuals can enter into the compartment of heavy problem alcoholics directly by contacting with light problem alcoholics or heavy problem alcoholics and the heavy problem alcoholics who receive treatment can relapse into the compartment of heavy problem alcoholics are also considered. First, the dynamics of our model on unweighted networks, including the basic reproduction number, existence and stability of equilibria are studied. Second, the models with fixed weighted and adaptive weighted networks are introduced and investigated. At last, some simulations are presented to illustrate and extend our results. Our results show that it is very important to treat alcoholics to quit the drinking.

Heavy drinking increases the risk of injury, adverse physical and mental health outcomes, and loss of productivity. Nonetheless, patterns of alcohol use and related symptomatology among military personnel remain poorly understood. A latent class analysis (LCA) was used to explore the presence of subgroups of alcohol users among Canadian Armed Forces (CAF) Regular Forces members. Correlates of empirically derived subgroups were further explored. Analyses were performed on a subsample of alcohol users who participated in a 2008/09 cross-sectional survey of a stratified random sample of currently serving CAF Regular Force members (N = 1980). Multinomial logistic regression models were conducted to verify physical and mental health differences across subgroups of alcohol users. All analyses were adjusted for complex survey design. A 4-class solution was considered the best fit for the data. Subgroups were labeled as follows: Class 1 - Infrequent drinkers (27.2%); Class 2 - Moderate drinkers (41.5%); Class 3 - Regular binge drinkers with minimal problems (14.8%); and Class 4 - Problem drinkers (16.6%). Significant differences by age, sex, marital status, element, rank, recent serious injuries, chronic conditions, psychological distress, posttraumatic stress disorder, and depression symptoms were found across the subgroups. Problem drinkers demonstrated the most degraded physical and mental health. Findings highlight the heterogeneity of alcohol users and heavy drinkers among CAF members and the need for tailored interventions addressing high-risk alcohol use. Results have the potential to inform prevention strategies and screening efforts. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Full Text Available Adults with alcohol use disorders (AUDs show marked immediate reward selection (or Now bias in intertemporal choice tasks. This Now bias persists long into abstinence, suggesting an irreversible consequence of chronic alcohol abuse or a pre-existing AUD intermediate phenotype. However, some data show substantial Now bias among emerging adults (18-25, regardless of drinking behavior, suggesting age-dependent effects on Now bias. The objectives of the present study were to determine 1 whether Now bias is greater among emerging adults relative to adults, 2 whether any such age effect on Now bias is diminished in sub-clinical heavy alcohol users, and 3 whether having a problem drinking first degree relative is independently associated with elevated Now bias. To achieve these objectives, we used an intertemporal choice task to quantify Now bias in n=237 healthy participants (ages 18-40; 50% female, and a wide range of non-zero alcohol use, based on the Alcohol Use Disorders Identification Test (AUDIT. We found that among non-heavy drinkers, Now bias inversely correlated with age; this relationship was not present among heavy drinkers. We found no significant relationship between AUDIT score and Now bias among emerging adults, but AUDIT scores and Now bias were positively correlated among 26-40 year olds.

Evidence-based and reliable measures of addictive disorders are needed in general population-based assessments. One study suggested that heavy use over time (UOT) should be used instead of self-reported addiction scales (AS). This study compared UOT and AS regarding video gaming and internet use empirically, using associations with comorbid factors. Cross-sectional data from the 2011 French Survey on Health and Consumption on Call-up and Preparation for Defence-Day (ESCAPAD), cross-sectional data from the 2012 Swiss firstname.lastname@example.org study and two waves of longitudinal data (2010-13) of the Swiss Longitudinal Cohort Study on Substance Use Risk Factors (C-SURF). Three representative samples from the general population of French and Swiss adolescents and young Swiss men, aged approximately 17, 14 and 20 years, respectively. ESCAPAD: n =22 945 (47.4% men); email@example.com: n =3049 (50% men); C-SURF: n =4813 (baseline + follow-up, 100% men). We assessed video gaming/internet UOT ESCAPAD and firstname.lastname@example.org: number of hours spent online per week, C-SURF: latent score of time spent gaming/using internet] and AS (ESCAPAD: Problematic Internet Use Questionnaire, email@example.com: Internet Addiction Test, C-SURF: Gaming AS). Comorbidities were assessed with health outcomes (ESCAPAD: physical health evaluation with a single item, suicidal thoughts, and appointment with a psychiatrist; firstname.lastname@example.org: WHO-5 and somatic health problems; C-SURF: Short Form 12 (SF-12 Health Survey) and Major Depression Inventory (MDI). UOT and AS were correlated moderately (ESCAPAD: r = 0.40, email@example.com: r = 0.53 and C-SURF: r = 0.51). Associations of AS with comorbidity factors were higher than those of UOT in cross-sectional (AS: .005 ≤ |b| ≤ 2.500, UOT: 0.001 ≤ |b| ≤ 1.000) and longitudinal analyses (AS: 0.093 ≤ |b| ≤ 1.079, UOT: 0.020 ≤ |b| ≤ 0.329).

Studies on the role of labour market position and change in alcohol use during midlife are scarce and their results are inconclusive mainly due to their failure to define comprehensive and distinct labour market groups and the short periods of time studied. In this study we used different activity categories for men and women to examine alcohol use trajectories in midlife covering a period of 17 years. Using data from four sweeps of the National Child Development Study covering ages 33-50 (N=9960), we used multilevel growth models to study the association between labour market categories and longitudinal changes in weekly units of alcohol consumed. In the reference group of full-time employed men alcohol trajectory decreased over the follow-up period (β=-0.14; 95% CI -0.18 to -0.11) while in the reference group of employed women it increased (β=0.06; 95% CI 0.04 to 0.08). Men and women who were 'mainly sick' had significantly steeper declines in their alcohol consumption trajectory. Women who became employed after being homemakers had the steepest increase in alcohol use (β=0.05; 95% CI 0.01 to 0.09). Being employed is a strong determinant of alcohol use for men and women in midlife, making the workplace a good target for health promotion programmes and policies aimed at reducing alcohol use. Caution is needed when interpreting the health effects of alcohol consumption as low alcohol users may have previously been heavy drinkers. Published by the BMJ Publishing Group Limited.

Full Text Available The treatment of alcohol and drug users requires an extended reflection on the influence of the family and other social network groups of these individuals. Thus, this study, results of a qualitative study, aimed at investigating the presence of drug users in the social network of individuals undergoing treatment and the possible interventions of the mental health services in the social network of four users of alcohol in the municipality of Alegrete/RS. Interviews with users and families, genograms and eco-maps were used. The results indicated the presence of drug users in the family and in the other social network groups, and that the group for chemical dependants was the main intervention in these social networks. These results demonstrate the need for directing the actions of mental health to develop healthy bonds, to expand the social network and structure of the group in order to provide benefits which favor effective psychosocial rehabilitation.El tratamiento de adictos al alcohol y drogas requiere una reflexión amplia sobre la influencia de la familia y otros grupos de la red social de estos individuos.

The cognitive impairment and recovery associated with chronic alcohol abuse and subsequent abstinence is well understood. However, the recovery profile following heavy episodic or 'binge' use, which is common among some Australian Aboriginal users, has not been investigated thoroughly and no empirical studies have examined chronic use in this population. The aim of this study was to identify and compare cognitive impairment and recovery associated with chronic and episodic alcohol use among Aboriginal Australians. Longitudinal case-control design. Residential alcohol treatment programmes in northern Australia. Forty chronic alcohol users, 24 episodic users and 41 healthy controls [mean age = 34.24; standard deviation (SD) = 9.73]. Cognitive assessments of visual motor, attention, memory, learning and executive functions at baseline (start of treatment), then 4 weeks and 8 weeks later. Reassessment of 31% of participants an average of 11 months later (SD = 4.4) comparing those who remained abstinent (n = 5), those who relapsed (n = 11) and healthy controls (n = 19). At baseline, chronic and episodic alcohol users showed impaired visual motor, learning, memory and executive functions. With the exception of visual motor impairment, all deficits had improved to normal levels within 4 weeks. Visual motor deficits had normalized within 11 months. Performances did not differ at any time between chronic and episodic alcohol groups. In Aboriginal Australians, episodic drinking is associated with similar patterns of impairment and recovery as chronic alcohol use. Most cognitive deficits appear to recover within the first month of abstinence, while persisting visual motor problems recover within 1 year. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

A structural equation model examined sexual enhancement alcohol expectancies, heavy episodic drinking (HED), and risky sexual behavior as correlates of alcohol-involved rape in a sample of 353 college women. Prevalence of alcohol-involved rape was 15.6%. Sexual enhancement alcohol expectancies were indirectly associated with alcohol-involved rape via increased levels of HED, greater likelihood of sex while intoxicated, and number of sex partners. All forms of risky behavior were associated with alcohol-involved rape although HED had the strongest relationship. Findings suggest continued focus on women's positive alcohol expectancies and HED as risk factors for alcohol-involved rape. Implications for intervention will be discussed.

We review the experimental and theoretical status of baryons containing one heavy quark. The charm and bottom baryon states are classified and their mass spectra are listed. The appropriate theoretical framework for the description of heavy baryons is the Heavy Quark Effective Theory, whose general ideas and methods are introduced and illustrated in specific examples. We present simple covariant expressions for the spin wave functions of heavy baryons including p-wave baryons. The covariant spin wave functions are used to determine the Heavy Quark Symmetry structure of flavour-changing current-induced transitions between heavy baryons as well as one-pion and one-photon transitions between heavy baryons of the same flavour. We discuss 1/m Q corrections to the current-induced transitions as well as the structure of heavy to light baryon transitions. Whenever possible we attempt to present numbers to compare with experiment by making use of further model-dependent assumptions as e.g. the constituent picture for light quarks. We highlight recent advances in the theoretical understanding of the inclusive decays of hadrons containing one heavy quark including polarization. For exclusive semileptonic decays we discuss rates, angular decay distributions and polarization effects. We provide an update of the experimental and theoretical status of lifetimes of heavy baryons and of exclusive nonleptonic two body decays of charm baryons. (orig.)

One of the many challenges hindering the global response to the human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) epidemic is the difficulty of collecting reliable information about the populations most at risk for the disease. Thus, the authors empirically assessed a promising new method for estimating the sizes of most at-risk populations: the network scale-up method. Using 4 different data sources, 2 of which were from other researchers, the authors produced 5 estimates of the number of heavy drug users in Curitiba, Brazil. The authors found that the network scale-up and generalized network scale-up estimators produced estimates 5-10 times higher than estimates made using standard methods (the multiplier method and the direct estimation method using data from 2004 and 2010). Given that equally plausible methods produced such a wide range of results, the authors recommend that additional studies be undertaken to compare estimates based on the scale-up method with those made using other methods. If scale-up-based methods routinely produce higher estimates, this would suggest that scale-up-based methods are inappropriate for populations most at risk of HIV/AIDS or that standard methods may tend to underestimate the sizes of these populations.

Space construction will require heavy investment in the development of a wide variety of user interfaces for the computer-based tools that will be involved at every stage of construction operations. Using today's technology, user interface development is very expensive for two reasons: (1) specialized and scarce programming skills are required to implement the necessary graphical representations and complex control regimes for high-quality interfaces; (2) iteration on prototypes is required to meet user and task requirements, since these are difficult to anticipate with current (and foreseeable) design knowledge. We are attacking this problem by building a user interface development tool based on extensions to the spreadsheet model of computation. The tool provides high-level support for graphical user interfaces and permits dynamic modification of interfaces, without requiring conventional programming concepts and skills.

Cortical thickness abnormalities have been identified in youth using both alcohol and marijuana. However, limited studies have followed individuals pre- and post initiation of alcohol and marijuana use to help identify to what extent discrepancies in structural brain integrity are pre-existing or substance-related. Adolescents (N=69) were followed from ages 13 (pre-initiation of substance use, baseline) to ages 19 (post-initiation, follow-up). Three subgroups were identified, participants that initiated alcohol use (ALC, n=23, >20 alcohol use episodes), those that initiated both alcohol and marijuana use (ALC+MJ, n=23, >50 marijuana use episodes) and individuals that did not initiate either substance regularly by follow-up (CON, n=23, marijuana use episodes). All adolescents underwent neurocognitive testing, neuroimaging, and substance use and mental health interviews. Significant group by time interactions and main effects on cortical thickness estimates were identified for 18 cortical regions spanning the left and right hemisphere (pseffect, in cortical thickness by follow-up for individuals who have not initiated regular substance use or alcohol use only by age 19; modest between-group differences were identified at baseline in several cortical regions (ALC and CON>ALC+MJ). Minimal neurocognitive differences were observed in this sample. Findings suggest pre-existing neural differences prior to marijuana use may contribute to initiation of use and observed neural outcomes. Marijuana use may also interfere with thinning trajectories that contribute to morphological differences in young adulthood that are often observed in cross-sectional studies of heavy marijuana users.

Despite significant health risks, heavy drinking of alcohol among university students is a widespread problem; excessive drinking is part of the social norm. A growing number of studies indicate that short message service (SMS)-based interventions are cost-effective, accessible, require limited effort by users, and can enable continuous, real-time, brief support in real-world settings. Although there is emerging evidence for the effect of SMS-based interventions in reducing alcohol consumption, more research is needed. This study aims to test the effectiveness of a newly developed SMS-based intervention targeting excessive alcohol consumption among university and college students in Sweden. The study is a two-arm randomized controlled trial with an intervention (SMS programme) and a control (treatment as usual) group. Outcome measures will be investigated at baseline and at 3-month follow up. The primary outcome is total weekly alcohol consumption. Secondary outcomes are frequency of heavy episodic drinking, highest estimated blood alcohol concentration and number of negative consequences due to excessive drinking. This study contributes knowledge on the effect of automatized SMS support to reduce excessive drinking among students compared with existing support such as Student Health Centres.

An estimated 18 million adults in the United States meet the clinical criteria for diagnosis of alcohol abuse or alcoholism, a disorder ranked as the third leading cause of preventable death. In addition to brain pathology, heavy alcohol consumption is comorbid with damage to major organs including heart, lungs, liver, pancreas, and kidneys. Much of what is known about risk for and consequences of heavy consumption derive from rodent or retrospective human studies. The neurobiological effects of chronic intake in rodent studies may not easily translate to humans due to key differences in brain structure and organization between species, including a lack of higher-order cognitive functions, and differences in underlying prefrontal cortical neural structures that characterize the primate brain. Further, rodents do not voluntarily consume large quantities of ethanol (EtOH) and they metabolize it more rapidly than primates. The basis of the Monkey Alcohol Tissue Research Resource (MATRR) is that nonhuman primates, specifically monkeys, show a range of drinking excessive amounts of alcohol (>3.0 g/kg or a 12 drink equivalent per day) over long periods of time (12 to 30 months) with concomitant pathological changes in endocrine, hepatic, and central nervous system (CNS) processes. The patterns and range of alcohol intake that monkeys voluntarily consume parallel what is observed in humans with alcohol use disorders and the longitudinal experimental design spans stages of drinking from the EtOH-naïve state to early exposure through chronic abuse. Age- and sex-matched control animals self-administer an isocaloric solution under identical operant procedures. The MATRR is a unique postmortem tissue bank that provides CNS and peripheral tissues, and associated bioinformatics from monkeys that self-administer EtOH using a standardized experimental paradigm to the broader alcohol research community. This resource provides a translational platform from which we can better

To investigate cross-sectional associations between self-reported recent pain and alcohol use/abstinence, and previous-day pain and previous-week alcohol consumption in adults aged 50 + in six low- and middle-income countries (LMICs). The WHO Study on global AGEing and adult health (SAGE) Wave 1 (2007-2010) in China, Ghana, India, Mexico, Russia and South Africa is the data source. Prevalence of alcohol use/abstinence is reported by previous-day and previous-month pain. Multinomial logistic regressions (crude and adjusted for sex and country) tested associations between recent pain and alcohol use in the pooled multicountry sample. Across the six SAGE countries, about one-third of respondents reported alcohol use, being highest in Russia (74%) and lowest in India (16%). Holding the effects of sex and country constant, compared with abstainers, people with previous-day pain were more likely to be previous-day or other users. With regard to the quantity and frequency of alcohol use, people with previous-day pain were more likely to be non-heavy drinkers. Overall, we found that, in this population of older adults in six LMICs, recent pain was associated with moderate use of alcohol, although there were differences between countries. The findings provide a platform for country-specific research to better understand bi-directional associations between pain and alcohol in older adults. © 2016 John Wiley & Sons Ltd.

The thesis concerns itself with alcohol advertising. Alcohol is the most widespread habit-forming substance, yet its consumption is permitted in most countries all around the world, possibly restricted by the age of consumers only. Drinking alcohol cannot be either regulated or prohibited today. It has become commonplace for the majority of our lives. Being aware of its apparent risks, however, there is an effort to regulate at least alcohol advertising. The main objective of this work was to...

Research on attentional biases to alcohol images has used heterogeneous sets of stimuli (e.g., an isolated beer can or a group of people drinking). However, alcoholic beverage preferences play an important part in determining an individual's alcohol use pattern and may influence attentional biases, especially for inexperienced drinkers. The current study examined whether alcoholic beverage preferences affect event-related potential (ERP) indices of cue reactivity to different types of alcohol images (e.g., beer, wine, and distilled spirits) in heavy episodic drinkers. ERPs were recorded in 14 heavy episodic drinkers (7 male) who completed a Go/No-Go task using preferred and nonpreferred alcohol images with nonalcoholic beverage images as controls. Larger N2 amplitudes for preferred alcohol images were observed relative to control images and to nonpreferred alcohol images, indicating increased attentional capture by preferred beverages. P3 amplitudes and latencies were not sensitive to preferences, but latencies were delayed and amplitudes were enhanced on No-Go trials (i.e., trials requiring response inhibition). These results suggest that alcoholic beverage preference is a factor influencing alcohol cue reactivity in heavy-episodic-drinking college students. This information has methodological significance and may also be applied to improve treatment and prevention programs that focus on attentional bias modification and inhibitory control training.

Studies in experimental animals have shown varying and apparently opposite effects of alcohol on cardiac rhythm and conduction. Given acutely to non-alcoholic animals, ethanol may even have anti-arrhythmic properties whereas chronic administration clearly increases the animals' susceptibility to cardiac arrhythmias. Chronic heavy alcohol use has been incriminated in the genesis of cardiac arrhythmias in humans. The evidence has come from clinical observations, retrospective case-control studies, controlled studies of consecutive admissions for arrhythmias, and prospective epidemiological investigations. Furthermore, electrophysiological studies have shown that acute alcohol administration facilitates the induction of tachyarrhythmias in selected heavy drinkers. The role of alcohol appears particularly conspicuous in idiopathic atrial fibrillation. Occasionally, ventricular tachyarrhythmias have also been provoked by alcohol intake. Several lines of evidence suggest that heavy drinking increases the risk of sudden cardiac death with fatal arrhythmia as the most likely mechanism. According to epidemiological studies this effect appears most prominent in middle-aged men and is only partly explained by confounding traits such as smoking and social class. The basic arrhythmogenic effects of alcohol are still insufficiently delineated. Subclinical heart muscle injury from chronic heavy use may be instrumental in producing patchy delays in conduction. The hyperadrenergic state of drinking and withdrawal may also contribute, as may electrolyte abnormalities, impaired vagal heart rate control, repolarization abnormalities with prolonged QT intervals and worsening of myocardial ischaemia or sleep apnoea. Most of what we know about alcohol and arrhythmias relates to heavy drinking. The effect of social drinking on clinical arrhythmias in non-alcoholic cardiac patients needs to be addressed further.

The aims of the present study were to: (1) factor analyze a 13-item adolescent alcohol self-control behavior scale, (2) examine associations between frequency of self-control behavior use and alcohol consumption, and (3) to determine which self-control behaviors best predict alcohol use and consequences. A confidential standardized survey was used to collect data on participant's 30-day frequency, quantity, and heavy use of alcohol; alcohol-related consequences; and alcohol self-control behaviors. A principal component factor analysis produced the following three components: Healthy Alternatives (alpha=.81), Self-regulation (alpha=.72), and Assertive Communication (alpha=.73). MANOVAs indicated strong associations between frequency of use of the three types of self-control behaviors and alcohol consumption (p valuesadolescents, followed by Healthy Alternatives.
Children and adolescents are particularly vulnerable to the harmful effects of alcohol, with heavy drinking risking impaired brain development and future alcohol dependence. Advertisements increase expectancies about alcohol, leading to a greater likelihood of drinking. A systematic review of 13 longitudinal studies of over 38,000 young people found convincing evidence of an impact of media exposure and alcohol advertising on subsequent alcohol use, including initiation of drinking and heavier drinking among existing drinkers. All European countries, with the exception of the UK, have a ban on one or more types of advertising. Since self-regulation is reported as failing to prevent marketing which has an impact on younger people, and since advertising commonly crosses country borders, there is an argument to approximate advertising rules across Europe banning alcohol advertising targeted at young people, a highly cost-effective measure to reduce harmful alcohol use, and one supported by European citizens and case law.

The effects of D-cycloserine (DCS) in animal models of anxiety disorders and addiction indicate a role for N-methyl D-aspartate (NMDA) receptors in extinction learning. Exposure/response prevention treatments for anxiety disorders in humans are enhanced by DCS, suggesting a promising co-therapy regime, mediated by NMDA receptors. Exposure/response prevention may also be effective in problematic drinkers, and DCS might enhance habituation to cues in these individuals. Since heavy drinkers show ostensible conditioned responses to alcohol cues, habituation following exposure/response prevention should be evident in these drinkers, with DCS enhancing this effect. The objective of this study is to investigate the effect of DCS on exposure/response prevention in heavy drinkers. In a randomised, double-blind, placebo-controlled study, heavy social drinkers recruited from the community received either DCS (125 mg; n = 19) or placebo (n = 17) 1 h prior to each of two sessions of exposure/response prevention. Cue reactivity and attentional bias were assessed during these two sessions and at a third follow-up session. Between-session drinking behaviour was recorded. Robust cue reactivity and attentional bias to alcohol cues was evident, as expected of heavy drinkers. Within- and between-session habituation of cue reactivity, as well as a reduction in attentional bias to alcohol cues over time was found. However, there was no evidence of greater habituation in the DCS group. Subtle stimulant effects (increased subjective contentedness and euphoria) which were unrelated to exposure/response prevention were found following DCS. DCS does not appear to enhance habituation of alcohol cue reactivity in heavy non-dependent drinkers. Its utility in enhancing treatments based on exposure/response prevention in dependent drinkers or drug users remains open.

To describe the volume and patterns of alcohol consumption up to and including 2012, and to estimate the burden of disease attributable to alcohol consumption as measured in deaths and disability-adjusted life years (DALYs) lost in the Americas in 2012. Measures of alcohol consumption were obtained from the World Health Organization (WHO) Global Information System on Alcohol and Health (GISAH). The burden of alcohol consumption was estimated in both deaths and DALYs lost based on mortality data obtained from WHO, using alcohol-attributable fractions. Regional groupings for the Americas were based on the WHO classifications for 2004 (according to child and adult mortality). Regional variations were observed in the overall volume of alcohol consumed, the proportion of the alcohol market attributable to unrecorded alcohol consumption, drinking patterns, prevalence of drinking, and prevalence of heavy episodic drinking, with inhabitants of the Americas consuming more alcohol (8.4 L of pure alcohol per adult in 2012) compared to the world average. The Americas also experienced a high burden of disease attributable to alcohol consumption (4.7% of all deaths and 6.7% of all DALYs lost), especially in terms of injuries attributable to alcohol consumption. Alcohol is consumed in a harmful manner in the Americas, leading to a high burden of disease, especially in terms of injuries. New cost-effective alcohol policies, such as increasing alcohol taxation, increasing the minimum legal age to purchase alcohol, and decreasing the maximum legal blood alcohol content while driving, should be implemented to decrease the harmful consumption of alcohol and the resulting burden of disease.

Heavy drinking is common among college students and typically occurs in social contexts. Heavy drinking when alone, however, is less common. The present study hypothesized that students who drink heavily when alone (HD-Alone) would differ from college students who only drink heavily in social contexts (Social HD). Forty-nine HD-Alone students (at least one heavy-drinking episode when alone), 213 Social HDs, and 63 non-heavy drinkers (Non-HDs) were compared on alcohol-related consequences, drinking milestones, alcohol-outcome expectancies, and symptoms of depression. HD-Alone students reported more negative drinking consequences, earlier onset of regular drinking, more alcohol expectancies, less self-efficacy and motivation to reduce drinking, and higher depression scores than Social HDs and Non-HDs. Findings imply individual differences among heavy-drinking college students according to their drinking context.
Full Text Available Purpose of this study is to explore those factors which affect the health of students in postadolescent age, focusing on smoking and alcohol use, especially in regard to ways of predicting adoption of this behavior and its frequency to detect future users of tobacco and alcohol use but also high-risk groups, i.e. those people who are led to abuses. On the basis of the research part is the Theory of Planned Behaviour, the axes of which are to be investigated. Specifically, the factors evaluated, except for population parameters, behavioral attitudes, i.e. attitudes towards the behavior of tobacco use and alcohol regulations subjective perceptions and perceptions of control, perceived behavioral control and self-efficacy. Intention is explored to continue or start using tobacco and alcohol in the future and evaluate the behavior. The sample consisted of 138 students of postadolescent age, 18-25 years of both sexes, all of the University of Peloponnese and the Technological Educational Institute of Kalamata, Department of Sparta, Greece. The results of a series of statistical analysis, via SPSS 21.0 statistical program revealed the predictive power of perceived behavioral control and subjective norms to the intention of interpreting 64% of the variance of the latter, of the attitudes toward alcohol in relation to intention that interpret 69% of the variance, of the normative beliefs toward smoking with 69% range of interpretation to the dependent variable, of the perceived behavioral control of smoking with 72% and of the attitudes toward smoking with 77% of interpretation. The results demonstrate the significance and application in universities and technological educational institutes appropriate primary preventive interventions for students nonusers of tobacco and alcohol and appropriate programs of secondary and tertiary prevention in heavy users of tobacco and alcohol use and high-risk individual.

Unrecorded alcohol constitutes about 30% of all alcohol consumed globally. The aims of this systematic review were to determine the epidemiology (occurrence, types, prevalence) of unrecorded alcohol consumption in different countries/regions, analyse the chemical composition of unrecorded alcohol and examine health outcomes caused by the consumption of unrecorded alcohol, based on either epidemiology or toxicology. A systematic search for, and qualitative analysis of, papers with empirical results on the different categories of unrecorded alcohol, based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Unrecorded alcohol was widespread in all regions of the world. Artisanal fermented beverages and spirits were the most common categories of unrecorded alcohol globally, and were available on all continents. In India, industrially produced spirits (country spirits) were most prevalent. In Russia and countries of the former Soviet Union, surrogate alcohols complemented artisanal spirits. Cross-border shopping was the most prevalent method of obtaining unrecorded alcohol in parts of Europe. Ethanol was the most harmful ingredient of unrecorded alcohol, and health consequences due to other ingredients found in unrecorded alcohol were scarce. However, as unrecorded alcohol is usually the least expensive form of alcohol available in many countries, it may contribute to higher rates of chronic and irregular heavy drinking. Very large amounts of alcohol are produced globally that go unrecorded. The primary harm from this kind of alcohol arises from the fact that it is typically much cheaper than licit alcohol. © 2014 Society for the Study of Addiction.

Full Text Available Purpose: This study aimed to assess alcohol consumption and the occurrence of alcohol-related seizures in patients with epilepsy within the last 12 months.Methods: In an epilepsy outpatient clinic, a standardized questionnaire was used to collect data retrospectively from consecutive adult epilepsy patients who had been suffering from the disease for at least 1 year. Logistic regression analyses were performed to identify independent predictors.Results: A total of 310 patients with epilepsy were included. Of these, 204 subjects (65.8% consumed alcohol within the last 12 months. Independent predictors for alcohol use were antiepileptic drug monotherapy (OR 1.901 and physicians' advice that a light alcohol intake is harmless (OR 4.102. Seizure worsening related to alcohol consumption was reported by 37 of the 204 patients (18.1% who had used alcohol. All 37 subjects had consumed large quantities of alcohol prior to the occurrence of alcohol-related seizures regardless of their usual alcohol-drinking behavior. The amount of alcohol intake prior to alcohol-related seizures was at least 7 standard drinks, which is equivalent to 1.4 L of beer or 0.7 L of wine. In 95% of cases, alcohol-related seizures occurred within 12 h after cessation of alcohol intake. Independent predictors for alcohol-related seizures were generalized genetic epilepsy (OR 5.792 and chronic heavier alcohol use (OR 8.955.Conclusions: Two-thirds of interviewed subjects had consumed alcohol within the last 12 months. This finding may be an underestimate due to patients' self-reporting and recall error. In all cases, the occurrence of alcohol related-seizures was associated with timely consumption of considerably large amounts of alcohol.

Full Text Available Research conducted in high-income countries has investigated influences of socioeconomic inequalities on drinking outcomes such as alcohol use disorders (AUD, however, associations between area-level neighborhood social deprivation (NSD and individual socioeconomic status with these outcomes have not been explored in Brazil. Thus, we investigated the role of these factors on drink-related outcomes in a Brazilian population, attending to male-female variations.A multi-stage area probability sample of adult household residents in the São Paulo Metropolitan Area was assessed using the WHO Composite International Diagnostic Interview (WMH-CIDI (n = 5,037. Estimation focused on prevalence and correlates of past-year alcohol disturbances [heavy drinking of lower frequency (HDLF, heavy drinking of higher frequency (HDHF, abuse, dependence, and DMS-5 AUD] among regular users (RU; odds ratio (OR were obtained.Higher NSD, measured as an area-level variable with individual level variables held constant, showed an excess odds for most alcohol disturbances analyzed. Prevalence estimates for HDLF and HDHF among RU were 9% and 20%, respectively, with excess odds in higher NSD areas; schooling (inverse association and low income were associated with male HDLF. The only individual-level association with female HDLF involved employment status. Prevalence estimates for abuse, dependence, and DSM-5 AUD among RU were 8%, 4%, and 8%, respectively, with excess odds of: dependence in higher NSD areas for males; abuse and AUD for females. Among RU, AUD was associated with unemployment, and low education with dependence and AUD.Regular alcohol users with alcohol-related disturbances are more likely to be found where area-level neighborhood characteristics reflect social disadvantage. Although we cannot draw inferences about causal influence, the associations are strong enough to warrant future longitudinal alcohol studies to explore causal mechanisms related to the
Understanding the effect of higher alcohol prices on alcohol demand according to oneâ€™s level of alcohol consumption is crucial while evaluating the effectiveness of using alcohol taxes as an alcohol-control medium. In this study, I estimate the differential responses to alcohol prices on alcohol demand for young adults by asking whether heavy drinkers are more responsive to higher alcohol prices than light and moderate drinkers. To conduct the analysis, I use the data from the National Long...

Heavy drinking among college students is a significant public health concern that can lead to profound social and health consequences, including alcohol use disorder. Behavioral economics posits that low future orientation and high valuation of alcohol (alcohol demand) combined with deficits in alternative reinforcement increase the likelihood of alcohol misuse (Bickel et al., 2011). Despite this, no study has examined the incremental utility of all three variables simultaneously in a comprehensive model METHOD: The current study uses structural equation modeling to test the associations between behavioral economic variables - alcohol demand (latent), future orientation (measured with a delay discounting task and the Consideration of Future Consequences (CFC) scale), and proportionate substance-related reinforcement - and alcohol consumption and problems among 393 heavy drinking college students. Two models are tested: 1) an iteration of the reinforcer pathology model that includes an interaction between future orientation and alcohol demand; and 2) an alternative model evaluating the interconnectedness of behavioral economic variables in predicting problematic alcohol use RESULTS: The interaction effects in model 1 were nonsignificant. Model 2 suggests that greater alcohol demand and proportionate substance-related reinforcement is associated with greater alcohol consumption and problems. Further, CFC was associated with alcohol-related problems and lower proportionate substance-related reinforcement but was not significantly associated with alcohol consumption or alcohol demand. Finally, greater proportionate substance-related reinforcement was associated with greater alcohol demand CONCLUSIONS: Our results support the validity of the behavioral economic reinforcer pathology model as applied to young adult heavy drinking.

The paper mentions the important thing that it was for the country, exporting the first shipping of crude de Castilla to a company of asphalts in United States. It was not a common sale, as those that it carries out the company with the crude of Cusiana or Cano Limon. The new of this shipping is that it was the first successful test of marketing the Colombian heavy crude in the exterior, since previously it was almost considered a curse to find heavy crude by the difficulties of its transport. Today it can be taken to any refinery of the world and the best test is that, after almost a year of efforts to overcome the barriers of the transport, the company achieved its conduction from the Castilla Field, in proximities to Villavicencio, until the Covenas Port, in the Caribbean Colombian coast

Although the misuse of firearms is necessary to the occurrence of firearm violence, there are other contributing factors beyond simply firearms themselves that might also be modified to prevent firearm violence. Alcohol is one such key modifiable factor. To explore this, we undertook a 40-year (1975-2014) systematic literature review with meta-analysis. One large group of studies showed that over one third of firearm violence decedents had acutely consumed alcohol and over one fourth had heavily consumed alcohol prior to their deaths. Another large group of studies showed that alcohol was significantly associated with firearm use as a suicide means. Two controlled studies showed that gun injury after drinking, especially heavy drinking, was statistically significant among self-inflicted firearm injury victims. A small group of studies investigated the intersection of alcohol and firearms laws and alcohol outlets and firearm violence. One of these controlled studies found that off-premise outlets selling takeout alcohol were significantly associated with firearm assault. Additional controlled, population-level risk factor and intervention studies, including randomized trials of which only 1 was identified, are needed. Policies that rezone off-premise alcohol outlets, proscribe blood alcohol levels and enhance penalties for carrying or using firearms while intoxicated, and consider prior drunk driving convictions as a more precise criterion for disqualifying persons from the purchase or possession of firearms deserve further study. © The Author 2016.

We examined the relationship between state-level income inequality and alcohol outcomes and sought to determine whether associations of inequality with alcohol consumption and problems would be more evident with between-race inequality measures than with the Gini coefficient. We also sought to determine whether inequality would be most detrimental for disadvantaged individuals. Data from 2 nationally representative samples of adults (n = 13,997) from the 2000 and 2005 National Alcohol Surveys were merged with state-level inequality and neighborhood disadvantage indicators from the 2000 US Census. We measured income inequality using the Gini coefficient and between-race poverty ratios (Black-White and Hispanic-White). Multilevel models accounted for clustering of respondents within states. Inequality measured by poverty ratios was positively associated with light and heavy drinking. Associations between poverty ratios and alcohol problems were strongest for Blacks and Hispanics compared with Whites. Household poverty did not moderate associations with income inequality. Poverty ratios were associated with alcohol use and problems, whereas overall income inequality was not. Higher levels of alcohol problems in high-inequality states may be partly due to social context.

Colliding two heavy nuclei at ultrarelativistic energies allows to create in the laboratory a bulk system with huge density, pressure and temperature and to study its properties. It is estimated that in Pb-Pb collisions at CERN-SPS we reach over an appreciable volume an energy density which exceeds by more than a factor 20 that of normal nuclear matter. At such densities, the hadrons are so closely packed that they interpenetrate; novel physics phenomena are expected to appear. QCD predicts that under such conditions a phase transition from a system composed of colourless hadrons to a Quark-Gluon Plasma (QGP) should occur. A rich ultrarelativistic heavy-ion physics programme is under way both at BNL-AGS and at CERN-SPS since 1986. The results obtained so far have led CERN to officially announce evidence for a new state of matter last year. A long-range programme of heavy-ion physics at higher energies is under way (BNL-RHIC) and in preparation (CERN-LHC). These lectures are meant as an introduction to the phy...

The tendency to approach alcohol-related stimuli is known as the alcohol approach bias and has been related to heavy alcohol use. It is currently unknown whether the alcohol approach bias is more pronounced after emotional priming. The main aim of this study was to investigate whether positive and negative emotional primes would modulate the alcohol approach bias. For this purpose a new contextual Emotional Prime - Approach Avoidance Task (EP-AAT) was developed, containing both negative and p...

A large volume of alcoholic beverages containing aliphatic alcohols is consumed worldwide. Previous studies have confirmed the presence of ethanol-induced immunosuppression in heavy drinkers, thereby increasing susceptibility to infectious diseases. However, the aliphatic alcohols contained in alcoholic beverages might also impair immune cell function, thereby contributing to a further decrease in microbicidal activity. Previous research has shown that aliphatic alcohols inhibit phagocytosis by granulocytes but their effect on human monocytes has not been studied. This is important as they play a crucial role in engulfment and killing of pathogenic microorganisms and a decrease in their phagocytic activity could lead to impaired antimicrobial defence in heavy drinkers. The aim of this study was to measure monocyte phagocytosis following their treatment with those aliphatic alcohols detected in alcoholic beverages. Monocytes were separated from human peripheral blood and phagocytosis of opsonized zymosan particles by monocytes treated with ethanol and aliphatic alcohols individually and in combination was determined. It was shown that these alcohols could suppress the phagocytic activity of monocytes in a concentration-dependent manner and when combined with ethanol, they caused a further decrease in phagocytosis. Due to their additive effects, it is possible that they may inhibit phagocytosis in a clinically meaningful way in alcoholics and episodic heavy drinkers thereby contribute to their increased susceptibility to infectious diseases. However, further research is needed to address this question.

The consumption of alcohol mixed with energy drinks (AmEDs) is a form of risky drinking among college students, a population already in danger of heavy drinking and associated consequences. The goals of the current longitudinal study were to (a) identify types of AmED users between the first and second year of college and (b) examine differences among these groups in rates of highrisk drinking and consequences over time. A random sample of college student drinkers (n = 1,710; 57.7% female) completed baseline and 6-month follow-up measures assessing alcohol-related behaviors. AmED use was endorsed by 40% of participants during the course of the study. As anticipated, four distinct groups of AmED users were identified (nonusers, initiators, discontinuers, and continuous users) and were significantly different from one another on drinking and consequence outcomes. Further, significant Time × Group interaction effects were observed for drinking and overall consequences. Generally, across all outcomes and time points, nonusers reported the lowest rates of drinking and consequences, whereas continuous users consistently reported the highest rates of drinking and consequences. Students who initiated AmED use during the course of the study also reported anabrupt increase in alcohol use and reported consequences. Findings suggest students who consistently engage in and initiate AmED use also engage in riskier drinking behaviors and experience higher rates of consequences. Interventions that specifically target AmED use may be warranted and have the potential to reduce alcohol-related consequences.

A new SAIRS alcoholism model with birth and death on complex heterogeneous networks is proposed. The total population of our model is partitioned into four compartments: the susceptible individual, the light problem alcoholic, the heavy problem alcoholic and the recovered individual. The spread of alcoholism threshold R0 is calculated by the next generation matrix method. When R0 alcohol free equilibrium is globally asymptotically stable, then the alcoholics will disappear. When R0 > 1, the alcoholism equilibrium is global attractivity, then the number of alcoholics will remain stable and alcoholism will become endemic. Furthermore, the modified SAIRS alcoholism model on weighted contact network is introduced. Dynamical behavior of the modified model is also studied. Numerical simulations are also presented to verify and extend theoretical results. Our results show that it is very important to treat alcoholics to control the spread of the alcoholism.

In 1983 the World Health Assembly declared alcohol-related problems to be among the world's major health concerns. Since then, alcohol consumption has risen in developing countries, where it takes a heavy toll. Alcohol-related problems are at epidemic levels in the successor states of the Soviet Union and are responsible for 3.5% of disability-adjusted life years (DALYs) lost globally. Substantial evidence exists of the relationship between the levels and patterns of alcohol consumption on the one hand and the incidence of alcohol-related problems on the other. Over the past 20 years, research has demonstrated the effectiveness of public policies involving, for example, taxation and restrictions on alcohol availability, in reducing alcohol-related problems. In the wake of rapid economic globalization, many of these policies at national and subnational levels have been eroded, often with the support of international financial and development organizations. Development agencies and international trade agreements have treated alcohol as a normal commodity, overlooking the adverse consequences of its consumption on productivity and health. WHO is in a strong position to take the lead in developing a global alcohol policy aimed at reducing alcohol-related problems, providing scientific and statistical support, capacity-building, disseminating effective strategies and collaborating with other international organizations. Such leadership can play a significant part in diminishing the health and social problems associated with alcohol use. PMID:10885168

There are important measurements of alcoholism that are poorly understood by physicians. Professional attitudes toward alcoholic patients are often counterproductive. Americans spend about $30 billion on alcohol a year and most adults drink alcohol. Even though traditional criteria allow for recognition of the disease, diagnosis is often made late in the natural course, when intervention fails. Alcoholism is a major health problem and accounts for 10 percent of total health care costs. Still, this country's 10 million adult alcoholics come from a pool of heavy drinkers with well defined demographic characteristics. These social, cultural and familial traits, along with subtle signs of addiction, allow for earlier diagnosis. Although these factors alone do not establish a diagnosis of alcoholism, they should alert a physician that significant disease may be imminent. Focus must be directed to these aspects of alcoholism if containment of the problem is expected.

servicio especializado ayudará a repensar sobre las acciones preventivas y educativas en el área de la salud.OBJECTIVE: To evaluate the pattern of tobacco consumption in clients of a service specializing in the treatment of psychoactive substance dependence. METHODS: This was a descriptive quantitative approach, undertaken in 2009, in an Alcohol and Drugs Psychosocial Care Center, located within the State of São Paulo. We used a questionnaire containing sociodemographic information and the Fargeström test in 48 attendees in a single day at this service. RESULTS: The sample was characterized as predominantly adult males, unmarried, with low educational levels, and who were currently employed. In relation to smoking, we identified a high frequency of current smokers, with moderate level of tobacco dependence, motivated to change their smoking habits. CONCLUSION: Knowing the smoking behavior among users of a specialized service can help professionals rethink preventive and educational actions in the area of health.

Full Text Available Alcohol consumption is customary in most cultures and alcohol abuse is common worldwide. For example, more than 50% of Americans consume alcohol, with an estimated 23.1% of Americans participating in heavy and/or binge drinking at least once a month. A safe and effective therapy for alcoholic liver disease (ALD in humans is still elusive, despite significant advances in our understanding of how the disease is initiated and progresses. It is now clear that acute alcohol binges not only can be acutely toxic to the liver, but also can contribute to the chronicity of ALD. Potential mechanisms by which acute alcohol causes damage include steatosis, dysregulated immunity and inflammation and altered gut permeability. Recent interest in modeling acute alcohol exposure has yielded new insights into potential mechanisms of acute injury, that also may well be relevant for chronic ALD. Recent work by this group on the role of PAI-1 and fibrin metabolism in mediating acute alcohol-induced liver damage serve as an example of possible new targets that may be useful for alcohol abuse, be it acute or chronic.

Elevated depression and stress have been linked to greater levels of alcohol problems among young adults even after taking into account drinking level. This study attempts to elucidate variables that might mediate the relation between symptoms of depression and stress and alcohol problems, including alcohol demand, future time orientation, and craving. Participants were 393 undergraduates (60.8% female, 78.9% White/Caucasian) who reported at least 2 binge-drinking episodes (4/5+ drinks for women/men, respectively) in the previous month. Participants completed self-report measures of stress and depression, alcohol demand, future time orientation, craving, and alcohol problems. In separate mediation models that accounted for gender, race, and weekly alcohol consumption, future orientation and craving significantly mediated the relation between depressive symptoms and alcohol problems. Alcohol demand, future orientation, and craving significantly mediated the relation between stress symptoms and alcohol problems. Heavy-drinking young adults who experience stress or depression are likely to experience alcohol problems, and this is due in part to elevations in craving and alcohol demand, and less sensitivity to future outcomes. Interventions targeting alcohol misuse in young adults with elevated levels of depression and stress should attempt to increase future orientation and decrease craving and alcohol reward value.

The association of social capital and alcohol consumption is one of the most robust empirical findings in health economics of the past decade. However, the direction of the relationship between the two is heavily dependent on which dimension of social capital is studied and which alcohol measure is used. In this paper, we examine the effect of social interactions and generalised trust on drinking in the general Danish population survey. Participants (n = 2569) were recruited as part of a larger study. The double-hurdle model for the volume of alcohol consumption and the multivariate logistic model for heavy episodic drinking were estimated. We found evidence that social networking with male friends, membership in voluntary organisations, and generalised trust were significantly associated with the mean volume of alcohol consumption and heavy drinking. We also observed that social support at the community level had a buffering effect against heavy episodic drinking. The findings support previous findings in which social interactions and generalised trust were found to predict individuals' volume of drinking and heavy episodic drinking. However, the results varied across the indicators.

Previous research has suggested that consuming alcohol mixed with energy drinks (AMED) increases overall alcohol consumption. However, there is limited research examining whether energy drinks are unique in their effects when mixed with alcohol, when compared with alcohol mixed with other caffeinated mixers (AOCM). Therefore, the aim of this survey was to investigate alcohol consumption on AMED occasions, to that on other occasions when the same individuals consumed AOCM or alcohol only (AO). A UK-wide online student survey collected data on the frequency of alcohol consumption and quantity consumed, as well as the number of negative alcohol-related consequences reported on AO, AMED and AOCM occasions (N=250). Within-subjects analysis revealed that there were no significant differences in the number of alcoholic drinks consumed on a standard and a heavy drinking session between AMED and AOCM drinking occasions. However, the number of standard mixers typically consumed was significantly lower on AMED occasions compared with AOCM occasions. In addition, when consuming AMED, students reported significantly fewer days consuming 5 or more alcohol drinks, fewer days mixing drinks, and fewer days being drunk, compared with when consuming AOCM. There were no significant differences in the number of reported negative alcohol-related consequences on AMED occasions to AOCM occasions. Of importance, alcohol consumption and negative alcohol-related consequences were significantly less on both AMED and AOCM occasions compared with AO occasions. The findings that heavy alcohol consumption occurs significantly less often on AMED occasions compared with AOCM occasions is in opposition to some earlier claims implying that greatest alcohol consumption occurs with AMED. The overall greatest alcohol consumption and associated negative consequences were clearly associated with AO occasions. Negative consequences for AMED and AOCM drinking occasions were similar, suggesting that energy

Full Text Available Abstract Background Paraga, an alcoholic herbal preparation that comes in different varieties had been shown to be commonly available to commercial drivers in southern Nigeria. This study aims to determine the prevalence and pattern of paraga use, and to evaluate the level of awareness of the risks entailed in taking paraga among intercity commercial drivers operating out of motor parks in Osogbo, southwest Nigeria. We administered a locally validated version of the WHO drug and alcohol survey questionnaire to 350 commercial drivers. Results Of the 350 questionnaires administered, 332 were used for the data analysis; the remaining 18 were rejected because they had too many missing data. The prevalence rate in the past one year was 53.6% and 43.2% for the past one month (current. Three-quarters were moderate to heavy users, and many take the drug while working. A total of 25.6% had been involved in road crashes after taking paraga and 36.7% had actually seen people getting drunk from taking paraga. Only 40% of the drivers thought paraga use was harmful to their health, the others believing it to have therapeutic values (25% or undecided (35.0%. Only 43.8% of the drivers would be willing to stop taking paraga. Conclusions Paraga use is popular among commercial drivers. Because of its alcoholic nature, drivers’ access to the concoction should be controlled and appropriate enforcement put in place.
Full Text Available Abstract Background In 2004, tuberculosis (TB was responsible for 2.5% of global mortality (among men 3.1%; among women 1.8% and 2.2% of global burden of disease (men 2.7%; women 1.7%. The present work portrays accumulated evidence on the association between alcohol consumption and TB with the aim to clarify the nature of the relationship. Methods A systematic review of existing scientific data on the association between alcohol consumption and TB, and on studies relevant for clarification of causality was undertaken. Results There is a strong association between heavy alcohol use/alcohol use disorders (AUD and TB. A meta-analysis on the risk of TB for these factors yielded a pooled relative risk of 2.94 (95% CI: 1.89-4.59. Numerous studies show pathogenic impact of alcohol on the immune system causing susceptibility to TB among heavy drinkers. In addition, there are potential social pathways linking AUD and TB. Heavy alcohol use strongly influences both the incidence and the outcome of the disease and was found to be linked to altered pharmacokinetics of medicines used in treatment of TB, social marginalization and drift, higher rate of re-infection, higher rate of treatment defaults and development of drug-resistant forms of TB. Based on the available data, about 10% of the TB cases globally were estimated to be attributable to alcohol. Conclusion The epidemiological and other evidence presented indicates that heavy alcohol use/AUD constitute a risk factor for incidence and re-infection of TB. Consequences for prevention and clinical interventions are discussed.

College men are more likely to engage in health-compromising behaviors including risky drinking behavior, and experience more alcohol-related problems, including violence and arrest, as compared to women. The study of masculine norms or societal expectations, defined as beliefs and values about what it means to be a man, is one promising area of investigation that may help explain within-group differences and differential rates of alcohol use among men. Using the gender social learning model, we investigated the role of positive alcohol expectancies as an underlying mediator between masculine norms and alcohol use among college men. Data from 804 college adult men ( Mean age = 20.43) were collected through a web-based assessment. Participants completed a self-report measure of binge drinking, frequency of drinking, quantity of drinks, conformity to masculine norms, and positive alcohol expectancies measures. Structural equation modeling was used to examine relations between masculine norms, alcohol expectancies and alcohol use. The masculine norms of "Playboy" and Risk-Taking were positively related to heavy alcohol use, while Emotional Control and Heterosexual Presentation were both negatively associated with alcohol use, after controlling for fraternity Greek status and positive expectancies. Playboy and Winning norms were positively associated with positive expectancies while Power Over Women was inversely related to positive expectancies which, in turn, were associated with heavier alcohol use. This study was a novel exploration into the multiple pathways and mediators through which positive alcohol expectancies may help explain and provide specificity to the masculinity and alcohol use relationship among college men.

Identifying novel ways to recruit smokers for treatment studies is important. In particular, certain subgroups of adult smokers, such as heavy-drinking smokers, are at increased risk for serious medical problems and are less likely to try quitting smoking, so drawing this hard-to-reach population into treatment is important for improving health outcomes. This study examined the utility of Facebook advertisements to recruit smokers and heavy-drinking smokers for treatment research and evaluated smoking and alcohol use and current treatment goals among those who responded to the Web-based survey. Using Facebook's advertising program, 3 separate advertisements ran for 2 months targeting smokers who were thinking about quitting. Advertisements were shown to adult (at least 18 years of age), English-speaking Facebook users in the greater New Haven, Connecticut, area. Participants were invited to complete a Web-based survey to determine initial eligibility for a smoking cessation research study. Advertisements generated 1781 clicks and 272 valid, completed surveys in 2 months, with one advertisement generating the most interest. Facebook advertising was highly cost-effective, averaging $0.27 per click, $1.76 per completed survey, and $4.37 per participant meeting initial screening eligibility. On average, those who completed the Web-based survey were 36.8 (SD 10.4) years old, and 65.8% (179/272) were female. Advertisements were successful in reaching smokers; all respondents reported daily smoking (mean 16.2 [SD 7.0] cigarettes per day). The majority of smokers (254/272, 93.4%) were interested in changing their smoking behavior immediately. Many smokers (161/272, 59.2%) also reported heavy alcohol consumption at least once a month. Among smokers interested in reducing their alcohol use, more were heavy drinkers (45/56, 80.4%) compared to non-heavy drinkers (11/56, 19.6%; χ(2)[1,N=272]=13.0, PSocial media advertisements designed to target smokers were cost-effective and

The purpose of this research was to examine whether authoritative, authoritarian, indulgent, and neglectful parenting styles were associated with adolescent alcohol use and heavy drinking, after controlling for peer use, religiosity, and other relevant variables. Structural equation modeling was used to estimate direct and indirect associations of parenting style with alcohol use and heavy drinking among 4,983 adolescents in Grades 7-12. Adolescents whose parents were authoritative were less likely to drink heavily than adolescents from the other three parenting styles, and they were less likely to have close friends who used alcohol. In addition, religiosity was negatively associated with heavy drinking after controlling for other relevant variables. Authoritative parenting appears to have both direct and indirect associations with the risk of heavy drinking among adolescents. Authoritative parenting, where monitoring and support are above average, might help deter adolescents from heavy alcohol use, even when adolescents have friends who drink. In addition, the data suggest that the adolescent's choice of friends may be an intervening variable that helps explain the negative association between authoritative parenting and adolescent heavy drinking.
Open heavy flavours and heavy quarkonium states are expected to provide essential informa- tion on the properties of the strongly interacting system fo rmed in the early stages of heavy-ion collisions at very high energy density. Such probes are espe cially promising at LHC energies where heavy quarks (both c and b) are copiously produced. The ALICE detector shall measure the production of open heavy flavours and heavy quarkonium st ates in both proton-proton and heavy-ion collisions at the LHC. The expected performances of ALICE for heavy flavour physics is discussed based on the results of simulation studies on a s election of benchmark channels

Contingency management (CM) has not been thoroughly evaluated as a treatment for alcohol abuse or dependence, in part because verification of alcohol use reduction requires frequent in-person breath tests. Transdermal alcohol sensors detect alcohol regularly throughout the day, providing remote monitoring and allowing for rapid reinforcement of reductions in use. The purpose of this study was to evaluate the efficacy of CM for reduction in alcohol use, using a transdermal alcohol sensor to provide a continuous measure of alcohol use. Participants were 13 heavy drinking adults who wore the Secure Continuous Remote Alcohol Monitoring (SCRAM) bracelet for three weeks and provided reports of alcohol and drug use using daily web-based surveys. In Week 1, participants were asked to drink as usual; in Weeks 2 and 3, they were reinforced on an escalating schedule with values ranging from $5 to $17 per day on days when alcohol use was not reported or detected by the SCRAM. Self-reports of percent days abstinent and drinks per week, and transdermal measures of average and peak transdermal alcohol concentration and area under the curve declined significantly in Weeks 2-3. A nonsignificant but large effect size for reduction in days of tobacco use also was found. An adjustment to the SCRAM criteria for detecting alcohol use provided an accurate but less conservative method for use with non-mandated clients. Results support the efficacy of CM for alcohol use reductions and the feasibility of using transdermal monitoring of alcohol use for clinical purposes. Copyright © 2011 Elsevier Ireland Ltd.

The risk of adverse events among alcohol-interactive medication users can occur with one standard alcoholic drink. Research on the extent to which this occurs is scant. To examine the prevalence and correlates of concurrent alcohol and alcohol-interactive (AI) medication use across different levels of risk for an alcohol-related adverse event in a nationally representative sample of American adults. Cross-sectional analysis of past year, self-reported drinking history as well as past month, self-reported and visually inspected prescription drug use data from the 1999-2000 and 2001-2002 NHANES questionnaire section (n = 8,246). Medications were considered AI if concurrent use of alcohol and the prescription drug could intensify the effects of alcohol, resulting in increased sedation, drowsiness, or dizziness. Weighted prevalence estimates and polytomous logistic regression accounted for the complex survey design. Overall, 13.5% took prescription AI medications, of which 5.6% reported alcohol consumption of three or more drinks on each drinking occasion. Correlates of such use were being a man [adjusted odds ratio (AOR): 4.37; 95% confidence interval (CI): 1.84-10.35], between the ages of 20 and 54 (AOR=12.28; 95% CI: 3.12-48.25), and currently smoking (AOR: 2.61; 95% CI: 1.28-5.29), with alcohol-abstaining AI users as the referent group. Combining alcohol and AI medications is a common phenomenon, and the risk of alcohol-related adverse drug events may be nontrivial. Screening for alcohol use before prescribing AI medications would be prudent. Better communication regarding the dangers of mixing alcohol with AI medications is warranted.

While studies have addressed alcohol use and related problems among college athletes, little is known about the drinking patterns of non-athletes who are sports fans. This study examines the relationship between alcohol use and interest in collegiate sports on two levels. First, do sports fans in college binge drink more and exhibit more negative alcohol-related outcomes than other students? Second, do colleges with large numbers of sports fans have higher rates of heavy drinking and accompanying secondhand effects affecting other students? The study analyzed the responses of a nationally representative sample of students who completed questionnaires in the spring of 1999 regarding their extracurricular activities and substance use. The responses of 3445 student sports fans were compared to those of 8405 students who were not sports fans. More sports fans drank alcohol, engaged in binge drinking, had a heavy drinking style and reported alcohol-related problems than nonfans. The percentage of sports fans at a school was associated with binge drinking rates and the secondhand effects. The implications for those working with college athletics and for alcohol prevention personnel are discussed. Copyright 2002 Elsevier Science Ltd.
Cancer is a multifactorial disease that results from complex interactions of numerous risk factors - genetic and environmental - over time, eventually leading to the diseased phenotypes. Thus, while epidemiological studies can point to risk factors, they cannot determine cause and effect relationships, and are unable to give biological and clinical insights into carcinogenesis. The link between any risk factor and carcinogenesis needs to be validated in experimental models. This is particularly true in epidemiological studies on alcohol consumption and its consequences. While there is no doubt that heavy alcohol consumption has devastating health effects, the inconsistencies in alcohol-related epidemiological studies and cancer suffer from possible sources of the variability in outcomes, ranging from inaccuracy of self-report of consumption to the problem of correlating cancer that started decades earlier to current or recent alcohol consumption. To further study the interactions between alcohol and cancer, the use of "Molecular Pathological Epidemiology" (MPE) advocated by Ogino et al. for dissecting the interplay between etiological factors, cellular and molecular characteristics, and disease progression in cancer is appropriate. MPE does not consider cancer as a single entity, rather it integrates analyses of epidemiological studies with the macroenvironment and molecular and microenvironment. This approach allows investigating the relationships between potential etiological agents and cancer based on molecular signatures. More research is needed to fully elucidate the link between heavy alcohol consumption and pancreatic cancer, and to further investigate the roles of acetaldehyde and FAEEs in pancreatic carcinogenesis.

Full Text Available Background and Aims: Epidemiological transition in the form of noncommunicable diseases (NCDs now becoming the main cause of mortality and morbidity is very much evident even in developing countries like India. Alcohol is an important risk factor for NCD. The use of alcohol is increasing especially in young people and women. This increased use can be attributed to aggressive and innovative marketing by alcohol, in spite of and due to restrictions on its marketing. Social media, in recent times, has been misused by alcohol companies for marketing their products legally, due to legal loophole. The present study examined the reach of alcohol companies on social media and the marketing strategies used by them. Design, Settings, Participants: Facebook, Twitter and YouTube were explored for accounts and content by alcohol companies for marketing their product. Policies of social media sites pertaining to alcohol marketing were also studied. Measurements: Alcohol marketing was measured in terms of content posted by alcohol companies, use of direct or surrogate advertisement and engagement with users. Findings: Alcohol companies have been conveniently using social media to target young urban population with direct and surrogate advertisements of their products. Current social media policies and laws are ineffective in controlling it. Conclusions: Amendment of laws pertaining to alcohol marketing to include social media also in its ambit is necessary. Social media sites should revise their policies to prevent alcohol marketing and promotion especially to underaged users.

Energy drinks are highly caffeinated beverages that are increasingly consumed by young adults. Prior research has established associations between energy drink use and heavier drinking and alcohol-related problems among college students. This study investigated the extent to which energy drink use might pose additional risk for alcohol dependence over and above that from known risk factors. Data were collected via personal interview from 1,097 fourth-year college students sampled from 1 large public university as part of an ongoing longitudinal study. Alcohol dependence was assessed according to DSM-IV criteria. After adjustment for the sampling design, 51.3%(wt) of students were classified as "low-frequency" energy drink users (1 to 51 days in the past year) and 10.1%(wt) as "high-frequency" users (≥52 days). Typical caffeine consumption varied widely depending on the brand consumed. Compared to the low-frequency group, high-frequency users drank alcohol more frequently (141.6 vs. 103.1 days) and in higher quantities (6.15 vs. 4.64 drinks/typical drinking day). High-frequency users were at significantly greater risk for alcohol dependence relative to both nonusers (AOR = 2.40, 95% CI = 1.27 to 4.56, p = 0.007) and low-frequency users (AOR = 1.86, 95% CI = 1.10, 3.14, p = 0.020), even after holding constant demographics, typical alcohol consumption, fraternity/sorority involvement, depressive symptoms, parental history of alcohol/drug problems, and childhood conduct problems. Low-frequency energy drink users did not differ from nonusers on their risk for alcohol dependence. Weekly or daily energy drink consumption is strongly associated with alcohol dependence. Further research is warranted to understand the possible mechanisms underlying this association. College students who frequently consume energy drinks represent an important target population for alcohol prevention. Copyright © 2010 by the Research Society on Alcoholism.

Full Text Available Chronic use of cocaine is associated with impairment in response inhibition but it is an open question whether and to which degree findings from chronic users generalize to the upcoming type of recreational users. This study compared the ability to inhibit and execute behavioral responses in adult recreational users and in a cocaine-free-matched sample controlled for age, race, gender distribution, level of intelligence, and alcohol consumption. Response inhibition and response execution were measured by a stop-signal paradigm. Results show that users and non users are comparable in terms of response execution but users need significantly more time to inhibit responses to stop-signals than non users. Interestingly, the magnitude of the inhibitory deficit was positively correlated with the individuals lifetime cocaine exposure suggesting that the magnitude of the impairment is proportional to the degree of cocaine consumed.
Full Text Available BACKGROUND: Clock genes govern circadian rhythms and shape the effect of alcohol use on the physiological system. Exposure to severe negative life events is related to both heavy drinking and disturbed circadian rhythmicity. The aim of this study was 1 to extend previous findings suggesting an association of a haplotype tagging single nucleotide polymorphism of PER2 gene with drinking patterns, and 2 to examine a possible role for an interaction of this gene with life stress in hazardous drinking. METHODS: Data were collected as part of an epidemiological cohort study on the outcome of early risk factors followed since birth. At age 19 years, 268 young adults (126 males, 142 females were genotyped for PER2 rs56013859 and were administered a 45-day alcohol timeline follow-back interview and the Alcohol Use Disorders Identification Test (AUDIT. Life stress was assessed as the number of severe negative life events during the past four years reported in a questionnaire and validated by interview. RESULTS: Individuals with the minor G allele of rs56013859 were found to be less engaged in alcohol use, drinking at only 72% of the days compared to homozygotes for the major A allele. Moreover, among regular drinkers, a gene x environment interaction emerged (p = .020. While no effects of genotype appeared under conditions of low stress, carriers of the G allele exhibited less hazardous drinking than those homozygous for the A allele when exposed to high stress. CONCLUSIONS: These findings may suggest a role of the circadian rhythm gene PER2 in both the drinking patterns of young adults and in moderating the impact of severe life stress on hazardous drinking in experienced alcohol users. However, in light of the likely burden of multiple tests, the nature of the measures used and the nominal evidence of interaction, replication is needed before drawing firm conclusions.
Full Text Available A subsample (n = 2,550 of the 2005 US National Alcohol Survey of adults was used to estimate prevalence and correlates of six externalities from alcohol abuse—family problems, assaults, accompanying intoxicated driver, vehicular accident, financial problems and vandalized property—all from another‘s drinking. On a lifetime basis, 60% reported externalities, with a lower 12-month rate (9%. Women reported more family/marital and financial impacts and men more assaults, accompanying drunk drivers, and accidents. Being unmarried, older, white and ever having monthly heavy drinking or alcohol problems was associated with more alcohol externalities. Publicizing external costs of drinking could elevate political will for effective alcohol controls.

Humans develop various clinical phenotypes of severe alcoholic liver disease, including alcoholic hepatitis and cirrhosis, generally after decades of heavy drinking. In such individuals, following each episode of drinking, their livers experience heightened intracellular and extracellular stresses that are closely associated with alcohol consumption and alcohol metabolism. This article focuses on the latest advances made in animal models on evolutionarily conserved homeostatic mechanisms for coping with and resolving these stress conditions. The mechanisms discussed include the stress-activated protein kinase JNK, energy regulator AMPK, autophagy and the inflammatory response. Over time, the host may respond variably to stress with protective mechanisms that are critical in determining an individual's vulnerability to developing severe alcoholic liver disease. A systematic review of these mechanisms and their temporal changes in animal models provides the basis for general conclusions, and raises questions for future studies. The relevance of these data to human conditions is also discussed.

Consumption of alcohol mixed with energy drinks (AmED) has been associated with both short- and long-term risks beyond those observed with alcohol alone. AmED use has been associated with heavy episodic (binge) drinking, risky behaviors, and risk of alcohol dependence. Laboratory research has demonstrated that AmED beverages lead to greater motivation to drink versus the same amount of alcohol consumed alone. However, the reason consumers find AmED beverages particularly appealing has been unclear. A recent report by Droste and colleagues (Alcohol Clin Exp Res 2014; 38:2087-2095) is the first study to investigate motivations related to AmED consumption and to determine which motives predict AmED consumption patterns, experience of drinking-related harms, and risk of alcohol dependence. The findings of this study significantly enhance our understanding of why AmED consumption is related to the risk of alcohol dependence and change our understanding of why consumers choose AmED beverages. The authors report that hedonistic motives strongly predicted AmED use and the harms associated with use. While intoxication-reduction motives predicted self-reported accidents and injuries, these motives did not predict AmED consumption patterns and risk of dependence. The risk of alcohol dependence may arise from repeated experiences when drinking alcohol is more pleasurable when energy drinks are consumed with the alcohol. This commentary will focus on why energy drinks might increase the rewarding properties of alcohol in social drinkers. In addition, discussion is provided explaining why more research on the neurotransmitter, adenosine, may actually inform us about the mechanisms contributing to the development of alcohol dependence.

Consumption of alcohol mixed with caffeinated energy drinks is becoming popular, and the number of pre-mixed caffeinated alcohol products on the worldwide market is increasing. There is public health concern and even occasional legal restriction relating to these drinks, due to associations with increased intoxication and harms. The precise nature and degree of the pharmacological relationship between caffeine and alcohol is not yet elucidated, but it is proposed that caffeine attenuates the sedative effects of alcohol intoxication while leaving motor and cognitive impairment unaffected. This creates a potentially precarious scenario for users who may underestimate their level of intoxication and impairment. While legislation in some countries has restricted production or marketing of pre-mixed products, many individuals mix their own energy drink-alcohol 'cocktails'. Wider dissemination of the risks might help balance marketing strategies that over-emphasize putative positive effects.

Alcohol use is a major contributor to injuries, mortality and the burden of disease. This review updates knowledge on risk relations between dimensions of alcohol use and health outcomes to be used in global and national Comparative Risk Assessments (CRAs). Systematic review of reviews and meta-analyses on alcohol consumption and health outcomes attributable to alcohol use. For dimensions of exposure: volume of alcohol use, blood alcohol concentration and patterns of drinking, in particular heavy drinking occasions were studied. For liver cirrhosis, quality of alcohol was additionally considered. For all outcomes (mortality and/or morbidity): cause of death and disease/injury categories based on International Classification of Diseases (ICD) codes used in global CRAs; harm to others. In total, 255 reviews and meta-analyses were identified. Alcohol use was found to be linked causally to many disease and injury categories, with more than 40 ICD-10 three-digit categories being fully attributable to alcohol. Most partially attributable disease categories showed monotonic relationships with volume of alcohol use: the more alcohol consumed, the higher the risk of disease or death. Exceptions were ischaemic diseases and diabetes, with curvilinear relationships, and with beneficial effects of light to moderate drinking in people without heavy irregular drinking occasions. Biological pathways suggest an impact of heavy drinking occasions on additional diseases; however, the lack of medical epidemiological studies measuring this dimension of alcohol use precluded an in-depth analysis. For injuries, except suicide, blood alcohol concentration was the most important dimension of alcohol use. Alcohol use caused marked harm to others, which has not yet been researched sufficiently. Research since 2010 confirms the importance of alcohol use as a risk factor for disease and injuries; for some health outcomes, more than one dimension of use needs to be considered. Epidemiological

Full Text Available Identifica fatores associados ao estabelecimento, em 2003, da política de saúde no Brasil para usuários de álcool e outras drogas. Utiliza, como fonte privilegiada, a entrevista semi-estruturada, além da pesquisa bibliográfica e documental. Mostra que a abordagem do fenômeno álcool/drogas pelo Estado brasileiro surgiu no início do século XX, com a criação de um aparato jurídico-institucional para coibir o comércio e uso de drogas. Esse aparato, permitiu o surgimento de práticas assistenciais de saúde para os usuários. Conclui-se que, ainda que a ordem jurídica e a saúde pública orientem-se por racionalidades nem sempre coincidentes, nessa área específica algumas práticas do campo jurídico contribuíram para a criação de condições que favoreceram o surgimento de uma política sanitária em 2003.The purpose of this article is to identify, factors that could be associated to the establishment of the country's health policy for users of alcohol and other drugs in 2003. It makes particular use of semi-structured interviews, as well as a study of the literature and documents. The article shows that the Brazilian State's approach to alcohol and drugs emerged in the early 20th century with the creation of a legal and institutional apparatus designed to control the sale and use of drugs, justified by the need to assure public security and public health. This apparatus permitted the development of healthcare practices for drug users based on the penalties it proposed. The article concludes that even though the rationales behind legal and public health measures do not always coincide, some of the practices that emerged in the legal sphere did help provide the conditions needed for the creation of a health policy for alcohol and drug users in Brazil in 2003.

Numerous studies have examined risk factors that are associated with heavy alcohol use; however, much of this research has not addressed factors that specifically relate to women's alcohol use. The current study has extended the previous literature on women's alcohol-use behavior by examining factors associated with risky drinking in young women traveling abroad (n = 55). Using a pretest-posttest design, we examined the influence of disinhibition sensation-seeking and endorsement of social enhancement alcohol expectancies in relation to participation in risky alcohol use while abroad for three weeks. Analyses confirmed that disinhibition sensation-seeking and social enhancement alcohol expectancies were associated with participation in risky alcohol-use behaviors while abroad (controlling for alcohol-use at the pretest). Analysis of qualitative data reinforced the importance of social facilitation in women's alcohol risk-taking. Participants' qualitative data also emphasized characteristics of situational disinhibition relating to travel as well as culturally-specific motivations for alcohol-use behaviors. Further research examining women's personal need for disinhibition and the role of situational disinhibition in motivating alcohol risk-taking is warranted. In addition, the current findings suggest that interventions focusing on the connections between alcohol use and enhancement of social relationships and the potential isolating effects of non-use are necessary.

The volatility of alcohol promotes the movement of alcohol from the bronchial circulation across the airway epithelium and into the conducting airways of the lung. The exposure of the airways through this route likely accounts for many of the biologic effects of alcohol on lung airway functions. The effect of alcohol on lung airway functions is dependent on the concentration, duration, and route of exposure. Brief exposure to mild concentrations of alcohol may enhance mucociliary clearance, stimulates bronchodilation, and probably attenuates the airway inflammation and injury observed in asthma and chronic obstructive pulmonary disease (COPD). Prolonged and heavy exposure to alcohol impairs mucociliary clearance, may complicate asthma management, and likely worsens outcomes including lung function and mortality in COPD patients. Nonalcohol congeners and alcohol metabolites act as triggers for airway disease exacerbations especially in atopic asthmatics and in Asian populations who have a reduced capacity to metabolize alcohol. Research focused on the mechanisms of alcohol-mediated changes in airway functions has identified specific mechanisms that mediate alcohol effects within the lung airways. These include prominent roles for the second messengers calcium and nitric oxide, regulatory kinases including PKG and PKA, alcohol- and acetaldehyde-metabolizing enzymes such as aldehyde dehydrogenase 2. The role alcohol may play in the pathobiology of airway mucus, bronchial blood flow, airway smooth muscle regulation, and the interaction with other airway exposure agents, such as cigarette smoke, represents opportunities for future investigation.

Divorce is associated with mental health problems, and heavy drinking is related to higher risk of divorce. Less is known about the effects of divorce in couples where one or both drinks heavily. There are, however, reasons to expect different consequences of divorce in heavy risk using couples compared to other couples. Spouses of abusers may experience the divorce as a relief, whereas abusers may find it extra difficult to be left single. The aim of the study is to compare the effect of divorce on mental health in heavy drinking couples to the effect in couples who drink less. Registry data were matched with data from the Nord-Trøndelag Health Study (HUNT 1 (T1) and 2 (T2)), enabling longitudinal analyses of approximately 11,000 couples. Interaction terms between 1) alcohol use on T1 and divorce between T1 and T2 (11 year time lag), and 2) alcohol use on T1 and time since divorce at T2 for all divorced couples were tested to examine changes in mental health between T1 and T2 for a) spouses of high-risk compared to low-risk users, and b) high-risk compared to low-risk users themselves. Data were analyzed using multivariate analysis of variance. There was a general effect of divorce on change in mental health between T1 and T2. We observed a significantly stronger worsening in mental health in female high-risk users and their spouses than in divorced low-risk users and their spouses. The results also suggest that the strain after divorce lasts longer in women with a high alcohol consumption and their spouses. Divorce seems to affect couples where one or both drink heavily more than couples with a low consumption. Also there was some evidence of a slower healing of mental health problems after divorce in alcohol exposed couples than in other couples. The results only reached significance for female high consumers and their spouses, but due to limited statistical power, safe conclusions about gender specific effects cannot be drawn.

Tobacco counter-advertising is effective at promoting smoking cessation. Few studies have evaluated the impact of alcohol warning advertising on alcohol consumption and possible mechanisms of effect. This pilot study aimed to assess whether alcohol warning advertising is effective in reducing urges to drink alcohol, if emotional responses to advertising explain any such effect or perceived effectiveness, and whether effects differ among heavier drinkers. One hundred fifty-two young adult (aged 18-25) alcohol users completed an online experiment in which they were randomly assigned to view one of three sets of six advertisements: (i) alcohol warning; (ii) alcohol promoting; or (iii) advertisements for non-alcohol products. Urges to drink alcohol were self-reported post-exposure. Affective responses (pleasure and arousal) to each advertisement and perceived effectiveness of each advertisement were recorded. Typical level of alcohol consumption was measured as a potential effect modifier. Participants exposed to alcohol warning advertisements reported significantly lower urges to drink alcohol than those who viewed either alcohol promoting or non-alcohol advertisements. This effect was fully mediated by negative affective responses (displeasure) to the alcohol warning advertisements. Perceived effectiveness of alcohol warning advertisements was associated with high arousal responses. Impact of the advertisements was unaffected by typical level of alcohol consumption, although the study was not powered to detect anything other than large effects. In line with findings from the tobacco literature, alcohol warning advertisements that elicit negative affect reduce urges to drink alcohol. Their impact upon actual consumption awaits investigation.
Integral healthcare model for treating problems caused by alcohol and other drugs: perceptions of users, their companions and practitioners O modelo de atenção integral à saúde para tratamento de problemas decorrentes do uso de álcool e outras drogas: percepções de usuários, acompanhantes e profissionais
Full Text Available Based on an integral healthcare model for the users of alcohol and other drugs, the expansion of Brazil's Psycho-Social Care Centers - Alcohol and Drugs (CAPS-AD is guided by the acknowledgement of users as citizens rather than patients, aiming at social reinsertion through an intersectoral approach and damage control, as well as other principles designed to build up integral healthcare services that are fair and egalitarian. This paper examines alcohol and drug users, their companions and healthcare practitioners in terms of the existing healthcare model, through a study conducted at two Psycho-Social Care Centers - Alcohol and Drugs in Recife, Pernambuco State. Focus groups, participative observation and documentary surveys were used to analyze the daily work routines at these Centers, exploring player perceptions and therapeutic projects. The findings indicate that users are still perceived as being ill, with medicalization and other traces of care models not used since the Psychiatric Reform. Social reinsertion was perceived as the main obstacle in integral healthcare. Restructuring this practice seems necessary, in order to break away from a culture of prejudice, exclusion and illness, as well as control models based on hospital-centric psychiatry.No Brasil, a expansão dos CAPS-AD, baseada em um modelo de atenção integral à saúde de usuários de álcool e outras drogas, preconiza a passagem da idéia de doentes para a de cidadãos; reinserção social e intersetorialidade das ações; adoção da redução de danos e outros princípios para atenção integral justa e equânime; entretanto, a literatura aponta para manutenção da lógica de controle que surge com o saber médico do século XVIII. O objetivo desse trabalho foi investigar a percepção de usuários, acompanhantes e profissionais, acerca do modelo de atenção à saúde de usuários de drogas.

To describe patterns of 'liking' alcohol marketing social media pages, and determine related alcohol consumption patterns among young Australians. Participants were 1,001 Australians aged 15-29 years who completed a cross-sectional online survey. Logistic regression and ordinal logistic regression were used. A quarter (249/1001, 24.9%) liked at least one of the alcohol marketing social media pages, most commonly brands of spirits, cider and alcohol retailers. Underage participants were as likely as older participants to report liking these pages.

Brain abnormalities in adolescent heavy drinkers may result from alcohol exposure, or stem from pre-existing neural features. This longitudinal morphometric study investigated 40 healthy adolescents, ages 12-17 at study entry, half of whom (n=20) initiated heavy drinking over the 3-year follow-up. Both assessments included high-resolution magnetic resonance imaging. FreeSurfer was used to segment brain volumes, which were measured longitudinally using the newly developed quantitative anatomic regional change analysis (QUARC) tool. At baseline, participants who later transitioned into heavy drinking showed smaller left cingulate, pars triangularis, and rostral anterior cingulate volume, and less right cerebellar white matter volumes (pteens. Over time, participants who initiated heavy drinking showed significantly greater volume reduction in the left ventral diencephalon, left inferior and middle temporal gyrus, and left caudate and brain stem, compared to substance-naïve youth (pbrain regions in future drinkers and greater brain volume reduction in subcortical and temporal regions after alcohol use was initiated. This is consistent with literature showing pre-existing cognitive deficits on tasks recruited by frontal regions, as well as post-drinking consequences on brain regions involved in language and spatial tasks.

anticonvulsants reduced drinks/drinking days (11 studies, 1126 participants, mean difference (MD) -1.49, 95% Cl -2.32 to -0.65) and heavy drinking (12 studies, 1129 participants, standardised mean difference (SMD) -0.35, 95% Cl -0.51 to -0.19). Moreover, withdrawal for medical reasons (12 studies, 1410 participants, RR 1.22, 95% Cl 0.58 to 2.56, moderate-quality evidence) showed no evidence of difference, but for specific adverse effects (nine studies, 1164 participants), two of 18 adverse event outcomes favoured placebo. The direction of results was confirmed by subgroup analyses for topiramate and partially for gabapentin and valproate.Anticonvulsants versus naltrexone: No evidence of difference was shown in dropout rates (five studies, 528 participants, RR 0.74, 95% CI 0.52 to 1.06), severe relapse rates (four studies, 427 participants, RR 0.69, 95% Cl 0.44 to 1.07) and continuous abstinence rates (five studies, 528 participants, RR 1.21, 95% Cl 0.99 to 1.49); anticonvulsants were associated with fewer heavy drinking days (three studies, 308 participants, MD -5.21, 95% Cl -8.58 to -1.83), more days to severe relapse (three studies, 244 participants, MD 11.88, 95% Cl 3.29 to 20.46) and lower withdrawal for medical reasons (three studies, 245 participants, RR 0.13, 95% Cl 0.03 to 0.58). At the current stage of research, randomised evidence supporting the clinical use of anticonvulsants to treat alcohol dependence is insufficient. Results are conditioned by heterogeneity and by the low number and quality of studies comparing anticonvulsants with other medications. The uncertainty associated with these results leaves to clinicians the need to balance possible benefits/risks of treatment with anticonvulsants versus other medications as supported by evidence of efficacy.

To review the consequences of the changes in Finnish alcohol policy in 2004, when quotas for travellers' tax-free imports of alcoholic beverages from other European Union (EU) countries were abolished, Estonia joined the EU and excise duties on alcoholic beverages were reduced in Finland by one-third, on average. A review of published research and routinely available data. Finland. Prices of alcoholic beverages, recorded and unrecorded alcohol consumption, data on criminality and other police statistics, alcohol-related deaths and hospitalizations, service use. Alcohol consumption increased 10% in 2004, clearly more than in the early 2000s. With few exceptions, alcohol-related harms increased. Alcohol-induced liver disease deaths increased the most, by 46% in 2004-06 compared to 2001-03, which indicates a strong effect on pre-2004 heavy drinkers. Consumption and harms increased most among middle-aged and older segments of the population, and harms in the worst-off parts of the population in particular. Alcohol taxation and alcohol prices affect consumption and related harms, and heavy drinkers are responsive to price. In Finland in 2004, the worst-off parts of the population paid the highest price in terms of health for cuts in alcohol prices. The removal of travellers' import quotas, which was an inherent part of creating the single European market, had serious public health consequences in Finland.

This review explores gender differences in relapse and characteristics of relapse events in alcohol and substance use. For alcohol, relapse rates were similar across gender. Although negative mood, childhood sexual abuse, alcohol-related self-efficacy, and poorer coping strategies predicted alcohol relapse, gender did not moderate these effects. Gender did moderate the association between marriage and alcohol relapse. For women, marriage and marital stress were risk factors for alcohol relapse; among men, marriage lowered relapse risk. This gender difference in the role of marriage in relapse may be a result of partner differences in problem drinking. Alcoholic women are more likely to be married to heavy drinking partners than are alcoholic men; thus, alcoholic women may be put at risk of relapse by marriage and alcoholic men may be protected by marriage. There are fewer studies documenting gender differences in substance abuse relapse so conclusions are limited and tentative. In contrast to the lack of gender differences in alcohol relapse rates, women appear less likely to experience relapse to substance use, relative to men. Women relapsing to substance use appear to be more sensitive to negative affect and interpersonal problems. Men, in contrast, may be more likely to have positive experiences prior to relapse.

Alcohol use disorder is underdiagnosed and undertreated, and up to 50% of alcohol-abstinent patients diagnosed with alcohol dependence relapse within the first year of treatment. Current treatments for the maintenance of alcohol abstinence in patients with alcohol use disorder have limited efficacy, and there is an urgent need for novel treatment strategies. Decreased cerebral glucose metabolism and increased brain uptake of acetate were recently reported in heavy drinkers, relative to controls. Given the switch of metabolic fuel from glucose to acetate in the alcohol-dependent brain, we investigated the potential therapeutic benefit of a ketogenic diet in managing alcohol withdrawal symptoms during detoxification. Male Sprague Dawley rats fed either ketogenic or regular diet were administered ethanol or water orally, twice daily for 6 days while the diet conditions were maintained. Abstinence symptoms were rated 6, 24, 48, and 72 hours after the last alcohol administration. Maintenance on a ketogenic diet caused a significant decrease in the alcohol withdrawal symptoms' "rigidity" and "irritability." Our preclinical pilot study suggests that a ketogenic diet may be a novel approach for treating alcohol withdrawal symptoms in humans. Copyright © 2017 by the Research Society on Alcoholism.

The study was carried out on a total of 1069 students (men and women from University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca, Romania. A general questionnaire assessed alcoholic beverage consumption, perception and preference. The main reasons associated with alcohol consumption were relaxation and socialization followed by taste and flavour. The most respondents are attracted by flavor and aroma of the favourite beverage. The participants in the study were not heavy social drinkers (only 1.7 % of participants consume alcohol every day. Beer and wine, were the alcoholic beverages ranked in the top of preferences. Our findings can provide information for educators and policymakers in Romania to implement target-orientated interventions against alcohol abuse at universities.

Full Text Available INTRODUCTION: A significant number of alcohol users is being recorded among young people while the limit when young people resorting to alcohol is approaching younger age groups. The aim of this study was to determine the general prevalence and structure of young consumers, as well as risk factors for alcohol use among adolescents. METHOD: The study included 200 respondents. The sample is defined out of classes of all secondary schools at the territory, where one class per school out all four high school grades entered the sample by random choice. The survey instrument was a specifically designed questionnaire and response rate of the classes was 100%. RESULTS: The survey showed that almost half of high school Kotor confirmed to have consumed alcohol. Among children who consume alcohol, almost one half indicated that their parents also use alcoholic beverages and the data show a statistically significant association between alcohol use among parents and their children. Respondents, who do not consume alcoholic beverages, consider the presence of smoking among their friends more often. Students who do not consume alcohol, more frequently point to the harmful effects of using these substances on health and a statistically significant difference between the attitudes of students who do not consume alcohol and those who do was demonstrated in relation to the harmful effects of alcohol on health. CONCLUSIONS: Alcohol use is widespread among young people and at the same time there is a significant association between alcohol consumption in parents and their children. The use of alcohol among young people in correlation with the use of tobacco, and the young who consume alcohol are more often found in the company of peers who smoke, compared to their friends who do not use alcohol. Children who do not use alcohol more frequently emphasize the harmful effects of its using on health

The harm from alcohol and tobacco use in low- and middle-income countries includes substantial economic cost to the individual. Our aim was to describe the expenditure on concurrent alcohol and tobacco use in relation to family income in two districts in Sri Lanka. A community-based cross-sectional study was carried out in two districts in Sri Lanka. We sampled 2684 men over 18 years of age using multistage cluster sampling. Cost of alcohol and cigarettes was calculated using the retail price for each brand and multiplying by the amount consumed. Among current alcohol users 63.1% were also smokers. Among current smokers 61.9% were also using alcohol. Prevalence of concurrent alcohol and tobacco use in urban areas was 20.1% and in rural areas 14%.

This paper traces the role of alcohol production and use in the daily lives of people in India, from ancient times to the present day. Alcohol use has been an issue of great ambivalence throughout the rich and long history of the Indian subcontinent. The behaviors and attitudes about alcohol use in India are very complex, contradictory and convoluted because of the many different influences in that history. The evolution of alcohol use patterns in India can be divided into four broad historical periods (time of written records), beginning with the Vedic era (ca. 1500-700 BCE). From 700 BCE to 1100 CE, ("Reinterpretation and Synthesis") is the time of emergence of Buddhism and Jainism, with some new anti-alcohol doctrines, as well as post-Vedic developments in the Hindu traditions and scholarly writing. The writings of the renowned medical practitioners, Charaka and Susruta, added new lines of thought, including arguments for "moderate alcohol use." The Period of Islamic Influence (1100-1800 CE), including the Mughal era from the 1520s to 1800, exhibited a complex interplay of widespread alcohol use, competing with the clear Quranic opposition to alcohol consumption. The fourth period (1800 to the present) includes the deep influence of British colonial rule and the recent half century of Indian independence, beginning in 1947. The contradictions and ambiguities-with widespread alcohol use in some sectors of society, including the high status caste of warriors/rulers (Kshatriyas), versus prohibitions and condemnation of alcohol use, especially for the Brahmin (scholar-priest) caste, have produced alcohol use patterns that include frequent high-risk, heavy and hazardous drinking. The recent increases in alcohol consumption in many sectors of the general Indian population, coupled with the strong evidence of the role of alcohol in the spread of HIV/STI infections and other health risks, point to the need for detailed understanding of the complex cross
Introduction Although alcohol consumption is a common lifestyle behavior with previous studies reporting positive effects of alcohol on chronic pain and rheumatoid arthritis, no studies to this date have examined alcohol consumption in patients with fibromyalgia. We examined the association between alcohol consumption and symptom severity and quality of life (QOL) in patients with fibromyalgia. Methods Data on self-reported alcohol consumption from 946 patients were analyzed. Subjects were grouped by level of alcohol consumption (number of drinks/week): none, low (≤3), moderate (>3 to 7), and heavy (>7). Univariate analyses were used to find potential confounders, and analysis of covariance was used to adjust for these confounders. Tukey HSD pairwise comparisons were used to determine differences between alcohol groups. Results Five hundred and forty-six subjects (58%) did not consume alcohol. Low, moderate, and heavy levels of alcohol consumption were reported for 338 (36%), 31 (3%), and 31 patients (3%), respectively. Employment status (P FIQ total score (P = 0.01), physical function (P fibromyalgia symptoms and better physical QOL than nondrinkers. Conclusions Our study demonstrates that low and moderate alcohol consumption was associated with lower fibromyalgia symptoms and better QOL compared to no alcohol consumption. The reasons for these results are unclear. Since recent studies have demonstrated that γ-Aminobutyric Acid (GABA) levels are low in fibromyalgia, and alcohol is known to be a GABA-agonist, future studies should examine whether alcohol could have a salutary effect on pain and other symptoms in fibromyalgia.

To examine short-term consequences associated with consuming alcohol and energy drinks compared with consuming alcohol without energy drinks. A longitudinal measurement-burst design (14-day bursts of daily surveys in four consecutive college semesters) captured both within-person variation across occasions and between-person differences across individuals. The analytic sample of late adolescent alcohol users included 4,203 days with alcohol use across up to four semesters per person from 508 college students. Adding energy drink use to a given day with alcohol use was associated with an increase in number of alcoholic drinks, a trend toward more hours spent drinking, elevated estimated blood alcohol content (eBAC), a greater likelihood of subjective intoxication, and more negative consequences of drinking that day. After controlling for eBAC, energy drink use no longer predicted subjective intoxication but was still associated with a greater number of negative consequences. The consumption of energy drinks may lead to increases in alcohol consumption and, after controlling for eBAC, negative consequences. Use of energy drinks plus alcohol represents an emerging threat to public health. Copyright © 2014 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.

Current estimates of the rates of alcohol-exposed pregnancies may underestimate prenatal alcohol exposure if alcohol consumption in early trimester 1, prior to awareness of pregnancy, is not considered. Extant literature describes predictors of alcohol consumption during pregnancy; however, alcohol consumption prior to awareness of pregnancy is a distinct behavior from consumption after becoming aware of pregnancy and thus may be associated with different predictors. The purpose of this study was therefore to examine prevalence and predictors of alcohol consumption by women prior to awareness of their pregnancy, and trajectories of change to alcohol use following pregnancy recognition. Pregnant women (n = 1,403) were prospectively recruited from general antenatal clinics of 4 public hospitals in Australian metropolitan areas between 2008 and 2013. Women completed detailed interviews about alcohol use before and after recognition of pregnancy. Most women (n = 850, 60.6%) drank alcohol between conception and pregnancy recognition. Binge and heavy drinking were more prevalent than low-level drinking. The proportion of women who drank alcohol reduced to 18.3% (n = 257) after recognition of pregnancy. Of women who drank alcohol, 70.5% ceased drinking, 18.3% reduced consumption, and 11.1% made no reduction following awareness of pregnancy. Socioeconomic status (SES) was the strongest predictor of alcohol use, with drinkers more likely to be of high rather than low SES compared with abstainers (OR = 3.30, p alcohol use prior to pregnancy recognition, age, pregnancy planning, and illicit substance use. In this sample of relatively high SES women, most women ceased or reduced drinking once aware of their pregnancy. However, the rate of alcohol-exposed pregnancies was higher than previous estimates when the period prior to pregnancy recognition was taken into account.

This study is the first investigation to explore the alcohol brand preferences of underage youth via a national survey. We conducted a pilot study of a new, internet-based alcohol brand survey with 108 youth ages 16–20 years who were recruited from an existing panel and had consumed alcohol in the past month. We ascertained respondents’ consumption of each of 380 alcohol brands during the past 30 days, including which brands of alcohol were consumed during heavy drinking episodes. Our findings suggest that, despite the wide variety of alcohol brands consumed by older adolescents in this study, alcohol preferences are concentrated among a relatively small number of brands. Accurate measurements of alcohol brand preferences will enable important new research into the factors that influence youth drinking behavior. This study establishes the feasibility and validity of a new methodology to determine patterns of brand-specific alcohol consumption among underage drinkers. PMID:22014249

Consumption of alcohol mixed with energy drinks (AmED) has been associated with both short and long-term risks beyond those observed with alcohol alone. AmED use has been associated with heavy episodic (binge) drinking, risky behaviors, and risk of alcohol dependence. Laboratory research has demonstrated that AmED beverages lead to greater motivation to drink versus the same amount of alcohol consumed alone. However, the reason consumers find AmED beverages particularly appealing has been unclear. A recent report by Droste and colleagues (2014) is the first study to investigate motivations related to AmED consumption and to determine which motives predict AmED consumption patterns, experience of drinking-related harms, and risk of alcohol dependence. The findings of this study significantly enhance our understanding of why AmED consumption is related to the risk of alcohol dependence and change our understanding of why consumers chose AmED beverages. The authors report that hedonistic motives strongly predicted AmED use and the harms associated with use. While intoxication-reduction motives predicted self-reported accidents and injuries, these motives did not predict AmED consumption patterns and risk of dependence. The risk of alcohol dependence may arise from repeated experiences when drinking alcohol is more pleasurable when energy drinks are consumed with the alcohol. This commentary will focus on why energy drinks might increase the rewarding properties of alcohol in social drinkers. In addition, discussion is provided explaining why more research on the neurotransmitter, adenosine, may actually inform us about the mechanisms contributing to the development of alcohol dependence.

This study examined neocortical brain morphometric differences between abstinent polysubstance dependent and alcohol-only dependent treatment seekers (ALC as well as light drinking controls (CON, the associations of cigarette smoking in these polysubstance users (PSU, and morphometric relationships to cognition and inhibitory control.All participants completed extensive neuropsychological assessments and 4 Tesla brain magnetic resonance imaging. PSU and ALC were abstinent for one month at the time of study. Parcellated morphological data (volume, surface area, thickness were obtained with FreeSurfer methodology for the following bilateral components: dorso-prefrontal cortex (DPFC, anterior cingulate cortex (ACC, orbitofrontal cortex (OFC, and insula. Regional group differences were examined and structural data correlated with domains of cognition and inhibitory control.PSU had significantly smaller left OFC volume and surface area and trends to smaller right DPFC volume and surface area compared to CON; PSU did not differ significantly from ALC on these measures. PSU, however, had significantly thinner right ACC than ALC. Smoking PSU had significantly larger right OFC surface area than non-smoking PSU. No significant relationships between morphometry and quantity/frequency of substance use, alcohol use, or age of onset of heavy drinking were observed. PSU exhibited distinct relationships between brain structure and processing speed, cognitive efficiency, working memory and inhibitory control that were not observed in ALC or CON.Polysubstance users have unique morphometric abnormalities and structure-function relationships when compared to individuals dependent only on alcohol and light drinking controls. Chronic cigarette smoking is associated with structural brain irregularities in polysubstance users. Further elucidation of these distinctive

Some salivary markers of alcohol abuse/dependence have been proposed so far: aminotransferases, gamma-glutamyltransferase, ethanol, ethyl glucuronide, ethyl sulfate, sialic acid, β-hexosaminidase A, oral peroxidase, methanol, diethylene/ethylene glycol, α-amylase, clusterin, haptoglobin, heavy/light chains of immunoglobulins and transferrin. To investigate the effect of chronic alcohol drinking and smoking on the activity (pKat/ml) and output (pKat/min) of salivary lysosomal exoglycosidases: α-fucosidase (FUC), α-mannosidase (MAN), β-galactosidase (GAL), and β-glucuronidase (GLU), and their applicability as markers of alcohol dependence. The activity of FUC, MAN, GAL and GLU was measured colorimetrically in the saliva of healthy social drinkers, alcohol-dependent non-smokers and alcohol-dependent smokers. We observed an increased salivary activity of FUC, GAL, GLU and MAN, as well as an increased output of GAL and GLU, in comparison with controls. The highest increase in the activity/output was found in salivary GLU and MAN (GLU, even 7- to 18-fold), and the least in GAL. We found an excellent sensitivity and specificity and a high accuracy (measured by the area under the ROC curve) for salivary FUC, GLU and MAN activities. The salivary GLU activity positively correlated with the number of days of last alcohol intoxication. Salivary activity of FUC, GAL and MAN, but not GLU, positively correlated with the periodontal parameters such as gingival index and papilla bleeding index. Although we found an excellent sensitivity and specificity as well as a high accuracy for the salivary activity of FUC, GLU and MAN, the GLU activity seems to be mostly applicable as a marker of chronic alcohol drinking (alcohol dependence). © The Author 2014.

Epidemiological and experimental studies have consistently linked alcoholic beverage consumption with the development of several chronic disorders, such as cancer, cardiovascular diseases, diabetes mellitus and obesity. The impact of drinking is usually dose-dependent, and light to moderate drinking tends to lower risks of certain diseases, while heavy drinking tends to increase the risks. Besides, other factors such as drinking frequency, genetic susceptibility, smoking, diet, and hormone st...

Internet alcohol marketing is not well studied despite its prevalence and potential accessibility and attractiveness to youth. The objective was to examine longitudinal associations between self-reported engagement with Internet alcohol marketing and alcohol use transitions in youth. A US sample of 2012 youths aged 15 to 20 was surveyed in 2011. An Internet alcohol marketing receptivity score was developed, based on number of positive responses to seeing alcohol advertising on the Internet, visiting alcohol brand Web sites, being an online alcohol brand fan, and cued recall of alcohol brand home page images. We assessed the association between baseline marketing receptivity and both ever drinking and binge drinking (≥6 drinks per occasion) at 1-year follow-up with multiple logistic regression, controlling for baseline drinking status, Internet use, sociodemographics, personality characteristics, and peer or parent drinking. At baseline, ever-drinking and binge-drinking prevalence was 55% and 27%, respectively. Many (59%) reported seeing Internet alcohol advertising, but few reported going to an alcohol Web site (6%) or being an online fan (3%). Higher Internet use, sensation seeking, having family or peers who drank, and past alcohol use were associated with Internet alcohol marketing receptivity, and a score of 1 or 2 was independently associated with greater adjusted odds of initiating binge drinking (odds ratio 1.77; 95% confidence interval, 1.13-2.78 and odds ratio 2.15; 95% confidence interval, 1.06-4.37 respectively) but not with initiation of ever drinking. Although high levels of engagement with Internet alcohol marketing were uncommon, most underage youths reported seeing it, and we found a prospective association between receptivity to this type of alcohol marketing and future problem drinking, making additional research and ongoing surveillance important.

Full Text Available 3,4-Methylenedioxymethamphetamine (MDMA is associated with changes in neurocognitive performance. Recent studies in laboratory animals have provided additional support for the neurodegeneration hypothesis. However, results from animal research need to be applied to humans with caution. Moreover, several of the studies that examine MDMA users suffer from methodological shortcomings. Therefore, a prospective cohort study was designed in order to overcome these previous methodological shortcomings and to assess the relationship between the continuing use of MDMA and cognitive performance in incipient MDMA users. It was hypothesized that, depending on the amount of MDMA taken, the continued use of MDMA over a two-year period would lead to further decreases in cognitive performance, especially in visual paired association learning tasks. 96 subjects were assessed at the second follow-up assessment: 31 of these were non-users, 55 moderate-users and 10 heavy-users. Separate repeated measures analyses of variance were conducted for each cognitive domain, including attention and information processing speed, episodic memory and executive functioning. Furthermore, possible confounders including age, general intelligence, cannabis use, alcohol use, use of other concomitant substances, recent medical treatment, participation in sports, level of nutrition, sleep patterns and subjective well-being were assessed.The Repeated measures analysis of variance (rANOVA revealed that a marginally significant change in immediate and delayed recall test performances of visual paired associates learning had taken place within the follow-up period of two years. No significant differences with the other neuropsychological tests were noted. It seems that MDMA use can impair visual paired associates learning in new users. However, in the recent study, further deterioration in continuing MDMA-users was not observed.
Full Text Available BackgroundAlcohol is attributable to many diseases and injury-related health conditions, and it is the fifth leading risk factor of premature death globally. Hence, the objective of this study was to assess the proportion and associated factors of problematic alcohol use among University students.Material and methodsCross-sectional study was conducted among 725 randomly selected University students from November to December 2015. Data were collected by self-administered questionnaire, and problematic alcohol use was assessed by Alcohol Use Disorder Identification Test. Chi-square test was used to show association of problematic use and each variable and major predicators was identified using logistic regression with 95% confidence interval (CI; and variables with p-value less than 0.05 were considered statistically significant.ResultsAbout 83 (11.4% of the samples were problematic alcohol users of which 6.8% had medium level problems and 4.6% had high level problems. Significantly associated variables with problematic alcohol use among students were presence of social phobia (AOR = 1.7, 95% CI: 1.0, 2.8, lifetime use of any substance (AOR = 6.9, 95% CI: 3.8, 12.7, higher score in students cumulative grade point average (AOR = 0.6, 95% CI: 0.4, 0.9, and having intimate friend who use alcohol (AOR = 2.2, 95% CI: 1.3, 3.8.ConclusionProblematic alcohol use among university students was common and associated with social phobia, poor academic achievement, lifetime use of any substance, and peer pressure. Strong legislative control of alcohol in universities is important to reduce the burden of alcohol.

While the harmful effects of alcohol during pregnancy are well-established, the consequences of alcohol intake during lactation have been far less examined. We reviewed available data on the prevalence of alcohol intake during lactation, the influence of alcohol on breastfeeding......, the pharmacokinetics of alcohol in lactating women and nursing infants and the effects of alcohol intake on nursing infants. A systematic search was performed in PubMed from origin to May 2013, and 41 publications were included in the review. Approximately half of all lactating women in Western countries consume...... alcohol while breastfeeding. Alcohol intake inhibits the milk ejection reflex, causing a temporary decrease in milk yield. The alcohol concentrations in breast milk closely resemble those in maternal blood. The amount of alcohol presented to nursing infants through breast milk is approximately 5...

Full Text Available Alcohol is the most consumed drug in the world, which could generate social and health problems, affecting users, people living with them and the society in general. The aim was to identify the best evidence of interventions to reduce alcohol abuse. An integrative review of the literature, conducted on LILACS, CINAHL, PUBMED and SCOPUS, through the descriptors “intervention studies” and “alcoholism”. Nineteen articles were selected, most of them classified as two regarding level of evidence. They involved interventions with alcohol users, the most efficient were short interventions, internet-based interventions and counselling. Although cessation of alcohol use was not proved through the interventions, results point to a significant reduction in consumption, increase of the availability to change drinking habit and effective impact of short interventions when compared to usual treatments. Short interventions constitute the best interventions to reduce alcohol abuse.

The purpose of this study was to examine the effects of alcoholism, alcohol consumption amount, and alcohol consumption pattern on mortality in a general population sample. This study used a 1970 prospective population sample (double-phase random sample) of 2,300 individuals ages 18-65 years in Stockholm County, which was also linked to mortality registers. A total of 1,895 individuals participated in a semi-structured, baseline psychiatric interview with a psychiatrist and social worker. Alcoholism and other mental disorders were recorded according to the eighth revision of the International Classification of Diseases (ICD-8). Information on the usual amount and frequency of alcohol consumption was collected at the psychiatric interview. Mortality up to year 2011 was assessed with Cox proportional hazard regression models. At baseline, there were 65 men and 21 women diagnosed with alcoholism. During followup, there were 873 deaths in the study population of 1,895. Alcoholism was associated with increased mortality rate. Former drinkers, but not never-drinkers, also had increased risk for mortality compared with moderate drinkers. We found no associations between heavy consumption and mortality. Frequent heavy episodic drinking was uncommon but related to mortality before, but not after, adjusting for an alcoholism diagnosis. Our results demonstrated that alcoholism—but not a reported high consumption of alcohol or frequent heavy episodic drinking—predicted a long-term risk of death.

Unrecorded alcohol includes illegally distributed alcohol as well as homemade or surrogate alcohol which is unintended for consumption by humans (e.g., cosmetics containing alcohol). The highest unrecorded alcohol consumption occurs in Eastern Europe and some of these countries have an over proportional liver cirrhosis mortality. Compounds besides ethanol have been hypothesized as being responsible for this observation. On the other hand, chemical investigations were unable to prove that unrecorded alcohol regularly contains contaminants above toxicological thresholds. However, illegally produced spirits regularly contain higher percentages of alcohol (above 45% by volume), but for considerably less costs compared with licit beverages, potentially causing more problematic patterns of drinking. In this review, it is investigated whether patterns of drinking rather than product composition can explain the liver cirrhosis mortality rates. Statistical examination of World Health Organization country data shows that the originally detected correlation of the percentage of unrecorded alcohol consumption and liver cirrhosis mortality rates disappears when the data is adjusted for the prevalence of heavy episodic drinking. It may be concluded that there is currently a lack of data to demonstrate causality between the composition of illicit spirits (e.g., higher levels of certain contaminants in home-produced products) and liver toxicity on a population scale. Exceptions may be cases of poisoning with antiseptic liquids containing compounds such as polyhexamethyleneguanidine, which were reported to be consumed as surrogate alcohol in Russia, leading to an outbreak of acute cholestatic liver injury, histologically different from conventional alcoholic liver disease.

Impaired control over alcohol is an important risk factor for heavy drinking among young adults and may mediate, in part, the association between personality risk and alcohol problems. Research suggests that trait impulsivity is associated with impaired control over alcohol; however, few studies of this association have included a range of impulsivity facets. The purpose of this study was to examine specific pathways from higher-order impulsivity factors to alcohol problems mediated via impaired control over alcohol. We also examined the moderating role of working memory in these associations. Young heavy drinkers (N=300) completed two multidimensional impulsivity measures (UPPS-P and BIS-11) along with self-report measures of impaired control over alcohol, alcohol use, and alcohol problems. Working memory was assessed using a computerized digit span task. Results showed that the impulsivity facets loaded onto two higher-order factors that were labeled response and reflection impulsivity. Response impulsivity predicted unique variance in self-reported impaired control and alcohol problems, whereas reflection impulsivity predicted unique variance in heavy drinking frequency only. Further, significant indirect associations were observed from response and reflection impulsivity to alcohol problems mediated via impaired control and heavy drinking frequency, respectively. Working memory and sensation seeking were not uniquely associated with the alcohol variables, and no support was found for the moderating role of working memory. The results help to clarify associations among impulsivity, impaired control, and alcohol problems, suggesting that impaired control may play a specific role in the pathway to alcohol problems from response impulsivity but not from reflection impulsivity.

Alcohol marketing on social networking sites (SNS) is associated with alcohol use among young people. Alcohol companies adapt their online marketing content to specific national contexts and responses to such content differ by national settings. However, there exists very little academic work comparing the association between alcohol marketing on SNS and alcohol use among young people in different national settings and across different SNS. Therefore, we aimed to extend the limited existing work by investigating and comparing the association between self-reported exposure to alcohol marketing on three leading SNS (Facebook, YouTube, and Twitter) and alcohol use among young people in diverse national contexts (India and Australia). Cross-sectional, self-report data were obtained from a convenience sample of 631 respondents (330 in India; 301 in Australia) aged 13-25 years via online surveys. Respondents answered questions on their drinking behaviors and involvement with alcohol marketing on SNS. Many respondents from both countries reported interacting with alcohol content online, predominantly on Facebook, followed by YouTube and then Twitter. The interaction was primarily in the forms of posting/liking/sharing/commenting on items posted on alcohol companies' social media accounts, viewing the event page/attending the event advertised by an alcohol company via social media, and/or accessing an alcohol website. Multivariate analyses demonstrated significant associations between respondents' interaction with alcohol content and drinking levels, with effects differing by SNS, demographic group, and country. For example, having friends who shared alcohol-related content was an important predictor of usual alcohol consumption for Indian respondents (p social media platforms and national contexts. The results highlight the need to formulate and implement strategies to effectively regulate the SNS alcohol marketing, especially among younger SNS users.

Fatty liver is an important clinical feature not only in alcoholic and non-alcoholic fatty liver diseases, but in other chronic liver diseases as well. Our aim was to elucidate the effect and relationship between habitual alcohol intake and obesity in the development of fatty liver disease. We enrolled 8,029 subjects undergoing abdominal ultrasonography with general medical examinations, and analyzed the factors associated with fatty liver based on daily alcohol intake, body mass index (BMI), and waist circumference. For fatty liver, BMI, waist circumference, total cholesterol, triglycerides, and fasting plasma glucose were significant and independent risk factors. Heavy alcohol intake (50 g/day) was a significant risk factor for fatty liver in women (odds ratio [OR], 3.35). Analysis based on the presence or absence of obesity revealed that moderate alcohol intake was a significant negative risk factor for fatty liver in both male and female obese (BMI ≥25 kg/m(2)) subjects (OR, 0.74 for non-obese and 0.39 for obese patients, respectively). Heavy alcohol intake was also a significant negative risk factor in obese males (0.62). In contrast, heavy alcohol intake was a risk factor in non-obese males (OR, 1.29) and in all females (OR, 2.22 for non-obese and 6.6 for obese patients, respectively). The influence of alcohol intake on fatty liver differed depending on the level of alcohol consumption, gender, and the presence of obesity, and showed biphasic effects.

Although alcohol consumption is a common lifestyle behavior with previous studies reporting positive effects of alcohol on chronic pain and rheumatoid arthritis, no studies to this date have examined alcohol consumption in patients with fibromyalgia. We examined the association between alcohol consumption and symptom severity and quality of life (QOL) in patients with fibromyalgia. Data on self-reported alcohol consumption from 946 patients were analyzed. Subjects were grouped by level of alcohol consumption (number of drinks/week): none, low (≤ 3), moderate (>3 to 7), and heavy (>7). Five hundred and forty-six subjects (58%) did not consume alcohol. Low, moderate, and heavy levels of alcohol consumption were reported for 338 (36%), 31 (3%), and 31 patients (3%), respectively. Employment status (P fibromyalgia symptoms and better physical QOL than nondrinkers. Our study demonstrates that low and moderate alcohol consumption was associated with lower fibromyalgia symptoms and better QOL compared to no alcohol consumption. The reasons for these results are unclear. Since recent studies have demonstrated that γ-Aminobutyric Acid (GABA) levels are low in fibromyalgia, and alcohol is known to be a GABA-agonist, future studies should examine whether alcohol could have a salutary effect on pain and other symptoms in fibromyalgia.
Full Text Available Epidemiological and experimental studies have consistently linked alcoholic beverage consumption with the development of several chronic disorders, such as cancer, cardiovascular diseases, diabetes mellitus and obesity. The impact of drinking is usually dose-dependent, and light to moderate drinking tends to lower risks of certain diseases, while heavy drinking tends to increase the risks. Besides, other factors such as drinking frequency, genetic susceptibility, smoking, diet, and hormone status can modify the association. The amount of ethanol in alcoholic beverages is the determining factor in most cases, and beverage types could also make an influence. This review summarizes recent studies on alcoholic beverage consumption and several chronic diseases, trying to assess the effects of different drinking patterns, beverage types, interaction with other risk factors, and provide mechanistic explanations.

The objective of this investigation was to establish the ability of the Secure Continuous Remote Alcohol Monitoring (SCRAM) alcohol sensor to detect different levels of self-reported alcohol consumption, and to determine whether gender and body mass index, alcohol dependence, bracelet version, and age of bracelet influenced detection of alcohol use. Heavy drinking adults (N = 66, 46% female) wore the SCRAM for 1-28 days and reported their alcohol use in daily Web-based surveys. Participant reports of alcohol use were matched with drinking episodes identified from bracelet readings. On days when bracelets were functional, 690 drinking episodes were reported and 502 of those episodes (72.8%) were detected using sensor data. Using generalized estimating equations, we found no gender differences in detection of reported drinking episodes (77% for women, 69% for men). In univariate analyses, at the level of fewer than 5 drinks, women's episodes were more likely to be detected, likely because of the significantly higher transdermal alcohol concentration levels of these episodes, whereas at the level of 5 or more drinks, there was no gender difference in detection (92.6% for women, 93.4% for men). In multivariable analyses, no variables other than number of drinks significantly predicted alcohol detection. In summary, the SCRAM sensor is very good at detecting 5 or more drinks; performance of the monitor below this level was better among women because of their higher transdermal alcohol concentration levels. Individual person characteristics and bracelet features were not related to detection after number of drinks was included. Minimal bracelet malfunctions were noted.

The rationale for the launching of the Alcohol Program from sugarcane in Brazil in the mid-1970s is described as an answer to the first ''oil crisis'' as well as a solution to the problem of the fluctuating sugar prices in the international market. The technical characteristics of ethanol as a fuel are given as well as a discussion of the evolution of the cost of production, environmental and social consequences. Regarding costs, ethanol production was close to 100 dollars a barrel in the initial stages of the Program in 1980 falling rapidly due to economies of scale and technological progress to half that value in 1990, followed by a slower decline in recent years. Considering the hard currency saved by avoiding oil importation through the significant displacement of gasoline by ethanol and the decrease in the amount of external debt that the displaced oil importation was able to provide it is possible to demonstrate that the Alcohol Program has been an efficient way of exchanging dollar debt by national currency subsidies which are paid by the liquid fossil fuel users. Even with this economic gains for society, the continuity of the Program is difficult to maintain. Two solutions to this problem are discussed: internal expansion of the use of ethanol and exports to industrialized countries where it could be used as an octane enhancer. The main attractiveness of the Program - the reduction of CO 2 emissions as compared to fossil fuels - is stressed, mainly as a solution for industrialized countries to fulfill their commitments with the United Nations Framework Climate Change Convention.

Full Text Available The aim of this study was to empirically identify different profiles of Spanish university alumni, based on their alcohol use over 9 years, and to further characterize them. A cohort study was carried out between 2005 and 2015 among university students (Compostela Cohort-Spain; n2015 = 415. Alcohol consumption was measured using the Alcohol Use Disorder Identification Test (AUDIT. A two-stage cluster analysis, based on their AUDIT total scores was carried out separately for males and females. The further characterization of every profile was based on demographic data, age at onset of alcohol use, positive alcohol-related expectancies, tobacco and cannabis use, as well as their answers to some European Addiction Severity Index items. Five different clusters were identified: Low users (29.2%, Moderated users (37.2%, At-risk users (14.2%, Decreasing users (13.2% and Large users (6.2% for females, and Low users (34.4%, At-risk users (25.6%, High-risk users (15.6%, Decreasing users (14.4% and Large users (10.0% for males. Being a cannabis user or a smoker was positively associated to those more hazardous clusters in both genders. Regarding females, significant differences in the age of onset and high positive expectancies were found. However, there were few significant differences among the groups in relation to their employment status and social relations. The results reveal the existence of different typologies of alcohol users among university alumni, with differences among males and females. Modifying positive expectancies, limiting access to alcohol at a young age, and reducing uses of other substances uses are key to promote healthier alcohol use profiles and to prevent hazardous uses.

Full Text Available OBJECTIVES:To evaluate family problems among crack/cocaine users compared with alcohol and other substance users.METHODS:A cross-sectional multi-center study selected 741 current adult substance users from outpatient and inpatient Brazilian specialized clinics. Subjects were evaluated with the sixth version of the Addiction Severity Index, and 293 crack users were compared with 126 cocaine snorters and 322 alcohol and other drug users.RESULTS:Cocaine users showed more family problems when compared with other drug users, with no significant difference between routes of administration. These problems included arguing (crack 66.5%, powder cocaine 63.3%, other drugs 50.3%, p= 0.004, having trouble getting along with partners (61.5%×64.6%×48.7%, p= 0.013, and the need for additional childcare services in order to attend treatment (13.3%×10.3%×5.1%, p= 0.002. Additionally, the majority of crack/cocaine users had spent time with relatives in the last month (84.6%×86.5%×76.6%, p= 0.011.CONCLUSIONS:Brazilian treatment programs should enhance family treatment strategies, and childcare services need to be included.

In this cross-cultural study, the authors attempted to identify high-risk subgroups for alcohol consumption among college students. American and Greek students (N = 132) answered questions about alcohol consumption, religious beliefs, attitudes toward drinking, advertisement influences, parental monitoring, and drinking consequences. Heavy drinkers in the American group were younger and less religious than were infrequent drinkers. In the Greek group, heavy drinkers tended to deny the negative results of drinking alcohol and use a permissive attitude to justify it, whereas infrequent drinkers were more likely to be monitored by their parents. These results suggest that parental monitoring and an emphasis on informing students about the negative effects of alcohol on their health and social and academic lives may be effective methods of reducing alcohol consumption. Classification tree analysis revealed that student attitudes toward drinking were important in the classification of American and Greek drinkers, indicating that this is a powerful predictor of alcohol consumption regardless of ethnic background.

Hazardous consumption of large quantities of alcohol is a major cause of ill-health in the former Soviet Union (fSU). The objective of this study was to describe episodic heavy drinking and other hazardous drinking behaviors in eight countries of the fSU. Data from national surveys of adults conducted in Armenia, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Russia, and Ukraine in 2001 were used (overall sample size 18,428; response rates 71-88%). Heavy episodic drinking, high alcohol intake, drinking alcohol during the working day, and using illegally produced strong spirits were examined. On average, 23% of men and 2% of women were defined as heavy episodic drinkers (> or = 2 l of beer or > or = 750 g bottle of wine or > or = 200 g strong spirits at least once every 2-3 weeks). This was more common in young males, women who are single or who are divorced/separated/widowed, in smokers, and in frequent alcohol drinkers. About half the respondents who drank strong spirits obtained at least some alcohol from private sources. Among drinkers, 11% of males and 7% of women usually took their first drink before the end of working day. Heavy episodic alcohol drinking is frequent in males throughout the region--although prevalence rates may have been affected by underreporting--but is still relatively rare in women. Alcohol policies in the region should address hazardous drinking patterns and the common use of illegally produced alcohol.

The WHO is preparing its global strategy on alcohol, and, in so doing, has been asked to consult with the alcohol industry on ways it could contribute in reducing the harm done by alcohol. This review asks which is more effective in reducing harm: the regulatory approaches that the industry does not favour; or the educational approaches that it does favour. The current literature overwhelmingly finds that regulatory approaches (including those that manage the price, availability, and marketing of alcohol) reduce the risk of and the experience of alcohol-related harm, whereas educational approaches (including school-based education and public education campaigns) do not, with industry-funded education actually increasing the risk of harm. The alcohol industry should not be involved in making alcohol policy. Its involvement in implementing policy should be restricted to its role as a producer, distributor, and marketer of alcohol. In particular, the alcohol industry should not be involved in educational programmes, as such involvement could actually lead to an increase in harm.

Human activities have dramatically changed the composition and organisation of soils. Industrial and urban wastes, agricultural application and also mining activities resulted in an increased concentration of heavy metals in soils. How plants and soil microorganisms cope with this situation and the sophisticated techniques developed for survival in contaminated soils is discussed in this volume. The topics presented include: the general role of heavy metals in biological soil systems; the relation of inorganic and organic pollutions; heavy metal, salt tolerance and combined effects with salinity; effects on abuscular mycorrhizal and on saprophytic soil fungi; heavy metal resistance by streptomycetes; trace element determination of environmental samples; the use of microbiological communities as indicators; phytostabilization of lead polluted sites by native plants; effects of soil earthworms on removal of heavy metals and the remediation of heavy metal contaminated tropical land.

Full Text Available Context: Alcohol use contributes to considerable morbidity and mortality worldwide. Screening for alcohol use and alcohol use disorder (AUD at the primary care level can help in reducing this burden. While several community studies have been conducted to estimate the AUD, there apparently are no studies on opportunistic screening in a primary care setting in India. Aims: The aim was to estimate the prevalence of alcohol use and AUD in a primary care setting. Settings and Design: A hospital-based cross-sectional study was conducted among adult male outpatients in a primary care setting in Puducherry, South India. Subjects and Methods: Male outpatients aged 18 and above were interviewed for alcohol use. Current alcohol users were screened for AUD using World Health Organization - AUD identification test (AUDIT questionnaire, respectively. Statistical Analysis Used: Proportions were used to describe the study population and the main study findings. The Chi-square test was used to find out the association between sociodemographic factors and alcohol use. Results: Of 256 subjects studied, 39.8% were found to be current alcohol users and 10.9% had AUD (AUDIT score ≥8. The sociodemographic factors did not show any association with an alcohol use in the current setting. Conclusion: Based on the findings of the present study, four current alcohol users are to be screened to identify one patient with AUD. Screening at the primary health care level can help in identifying the risk group and thus help in reducing the morbidity and mortality due to alcohol use in the population.

Alcohol consumption adds fuel to the HIV epidemic in sub-Saharan Africa (SSA). SSA has the highest prevalence of HIV infection and heavy episodic drinking in the world. Alcohol consumption is associated with behaviors such as unprotected sex and poor medication adherence, and biological factors such as increased susceptibility to infection, comorbid conditions, and infectiousness, which may synergistically increase HIV acquisition and onward transmission. Few interventions to decrease alcohol consumption and alcohol-related sexual risk behaviors have been developed or implemented in SSA, and few HIV or health policies or services in SSA address alcohol consumption. Structural interventions, such as regulating the availability, price, and advertising of alcohol, are challenging to implement due to the preponderance of homemade alcohol and beverage industry resistance. This article reviews the current knowledge on how alcohol impacts the HIV epidemic in SSA, summarizes current interventions and policies, and identifies areas for increased research and development.

A routine of light or moderate alcohol consumption (≤1 drink/day for women and 1 to 2 drinks/day for men) is associated with a lower risk for all-cause mortality, coronary artery disease (CAD), type 2 diabetes mellitus (T2D), heart failure (HF), and stroke. Conversely, heavy drinking, (>4 drinks/day) is associated with an increased risk for death and cardiovascular (CV) disease (CVD). Excessive alcohol intake trails behind only smoking and obesity among the 3 leading causes of premature deaths in the United States (US). Heavy alcohol use is a common cause of reversible hypertension (HTN), nonischemic dilated cardiomyopathy, atrial fibrillation (AF), and stroke (both ischemic and hemorrhagic). Among males aged 15 to 59 years, alcohol abuse is perhaps the leading cause of premature death. As such, the risk-to-benefit ratio of drinking is less favorable in younger individuals. A daily habit of light to moderate drinking is ideal for those who choose to consume alcohol regularly. Red wine in particular before or during the evening meal is linked with the best long-term CV outcomes. Most of the studies on alcohol and health are observational, and correlation does not prove causation. Health care professionals should not advise nondrinkers to begin drinking because of the paucity of randomized outcome data coupled with the potential for alcohol abuse even among seemingly low risk individuals.

Alcoholic beverages are widely consumed, resulting in a staggering economic cost in different social and cultural settings. Types of alcohol consumption vary from light occasional to heavy, binge drinking, and chronic alcohol abuse at all ages. In general, heavy alcohol consumption is widely recognized as a major epidemiological risk factor for chronic diseases and is detrimental to many organs and tissues, including bones. Indeed, recent findings demonstrate that alcohol has a dose-dependent toxic effect in promoting imbalanced bone remodeling. This imbalance eventually results in osteopenia, an established risk factor for osteoporosis. Decreased bone mass and strength are major hallmarks of osteopenia, which is predominantly attributed not only to inhibition of bone synthesis but also to increased bone resorption through direct and indirect pathways. In this review, we present knowledge to elucidate the epidemiology, potential pathogenesis, and major molecular mechanisms and cellular effects that underlie alcoholism-induced bone loss in osteopenia. Novel therapeutic targets for correcting alcohol-induced osteopenia are also reviewed, such as modulation of proinflammatory cytokines and Wnt and mTOR signaling and the application of new drugs.

In the large quark mass limit, an argument which identifies the mass of the heavy-light pseudoscalar or scalar bound state with the renormalized mass of the heavy quark is given. The following equation is discussed: m(sub Q) = m(sub B), where m(sub Q) and m(sub B) are respectively the mass of the heavy quark and the mass of the pseudoscalar bound state.

Prostate cancer has become a major public health problem worldwide although the etiology of prostate cancer remains largely unknown. Dietary factors, dietary supplements, and physical activity might be important in the prevention of the disease. In the majority of studies published, it was observed that high consumption of meat, alcohol and dairy products has been linked to a greater risk. Specifically, alcohol use, and particularly heavy use, may cause cancers of liver, esophagus, larynx, pharynx and oral cavity, with risks for the aero-digestive cancers. Moderate use among women has been related with increases in breast cancer. Alcohol consumption is a modifiable lifestyle factor that may affect prostate cancer risk. Alcohol alters the hormonal environment and in parallel, containing chemical substances such as flavonoids (red wine), may alter tumor cell growth. In this mini review, the relation between alcohol consumption and prostate cancer risk is analyzed.

Full Text Available Abstract Introduction The potential of alcohol withdrawal to cause acute coronary events is an area that needs the urgent attention of clinicians and researchers. Case presentation We report the case of a 52-year-old heavy-alcohol-using Sri Lankan man who developed electocardiogram changes suggestive of an acute coronary event during alcohol withdrawal. Despite the patient being asymptomatic, subsequent echocardiogram showed evidence of ischemic myocardial dysfunction. We review the literature on precipitation of myocardial ischemia during alcohol withdrawal and propose possible mechanisms. Conclusions Alcohol withdrawal is a commonly observed phenomenon in hospitals. However, the number of cases reported in the literature of acute coronary events occurring during withdrawal is few. Many cases of acute ischemia or sudden cardiac deaths may be attributed to other well known complications of delirium tremens. This is an area needing the urgent attention of clinicians and epidemiologists.

Alcoholic hepatitis (AH) is an acute inflammatory syndrome causing significant morbidity and mortality. The prognosis is strongly dependent on disease severity, as assessed by clinical scoring systems. Reliable epidemiological data as well as knowledge of the clinical course of AH are essential for planning and resource allocation within the health care system. Likewise, individual evaluation of risk is desirable in the clinical handling of patients with AH as it can guide treatment, improve patient information, and serve as strata in clinical trials. The present PhD thesis is based on three studies using a cohort of nearly 2000 patients diagnosed with AH in Denmark from 1999 to 2008 as a cohort, in a population-based study design. The aims of this thesis were as follows. (1) To describe the incidence and short- and long-term mortality, of AH in Denmark (Study I). (2) To validate and compare the ability of the currently available prognostic scores to predict mortality in AH (Study II). (3) To investigate the short- and long-term causes of death of patients with AH (Study III). During the study decade, the annual incidence rate in the Danish population rose from 37 to 46 per 106 for men and from 24 to 34 per 106 for women. Both short- and long-term mortality rose for men and women, and the increase in short-term mortality was attributable to increasing patient age and prevalence of cirrhosis. Our evaluation of the most commonly used prognostic scores for predicting the mortality of patients with AH showed that all scores performed similarly, with Area under the Receiver Operator Characteristics curves giving values between 0.74 and 0.78 for 28-day mortality assessed on admission. Our study on causes of death showed that in the short-term (thesis provides novel warranted epidemiological information about AH that shows increasing incidence and mortality rates. Consequently, it reiterates the fact that AH is a life-threatening disease and suggests that AH is an

By employing the heavy quark effective theory, the spectra of heavy hadrons, such as heavy mesons (Q-barq), heavy baryons (QQq and Qqq) and heavy multiquark systems (Q-barQ-barqq) are studied systemically. The results are compared with the predictions for Q-barQ-barqq in potential model
Heavy baryon decays are studied in the context of the Bethe-Salpeter approach to the heavy quark effective theory. A drastic reduction, in the number of independent form factors, is found. Results are presented both for heavy to heavy and heavy to light baryon decays. (orig.)

High energy, heavy-ion beams offer superior discrimination of tissue electron densities at very low radiation doses. This characteristic has potential for diagnostic medical imaging of neoplasms arising in the soft tissues and organs because it can detect smaller inhomogeneities than x rays. Heavy-ion imaging may also increase the accuracy of cancer radiotherapy planning involving use of accelerated charged particles. In the current physics research program of passive heavy-ion imaging, critical modulation transfer function tests are being carried out in heavy-ion projection radiography and heavy-ion computerized tomography. The research goal is to improve the heavy-ion imaging method until it reaches the limits of its theoretical resolution defined by range straggling, multiple scattering, and other factors involved in the beam quality characteristics. Clinical uses of the imaging method include the application of heavy-ion computerized tomography to heavy-ion radiotherapy planning, to the study of brain tumors and other structures of the head, and to low-dose heavy-ion projection mammography, particularly for women with dense breasts where other methods of diagnosis fail. The ions used are primarily 300 to 570 MeV/amu carbon and neon ions accelerated at the Lawrence Berkeley Laboratory Bevalac

. KLB encodes β-klotho, co-receptor for the liver-derived hormone fibroblast growth factor 21 (FGF21). In mice, FGF21 reduces alcohol intake, and human Fgf21 variants are enriched among heavy drinkers. Thus, the liver may limit alcohol consumption by secreting FGF21. However, whether full-length, active...... plasma FGF21 (FGF21 (1-181)) levels in humans increase acutely or sub-chronically in response to alcohol ingestion is uncertain. METHODS: We recruited 10 healthy, fasted male subjects to receive an oral water or alcohol bolus with concurrent blood sampling for FGF21 (1-181) measurement in plasma...... correlated fasting FGF21 (1-181) levels in 49 healthy, non-alcoholic subjects of mixed sex with self-reports of alcohol-related behaviors, emotional responses, and problems. Finally, we characterized the effect of recombinant human FGF21 injection on ad libitum alcohol intake in mice. RESULTS: We show...

Craving as a motivational determinant of drug use remains controversial because of ambiguous empirical findings. A behavioral economic approach may clarify the nature of craving, theorizing that subjective craving functionally reflects an acute increase in a drug's value. The current study tested this hypothesis via a multidimensional assessment of alcohol demand over the course of an alcohol cue reactivity procedure. One-way within-subjects design. Human laboratory environment. Heavy drinkers (n = 92) underwent exposures to neutral (water) cues followed by personalized alcohol cues. Participants were assessed for craving, alcohol demand, affect, and salivation following each exposure. Alcohol versus neutral cues significantly increased craving and multiple behavioral economic measures of the relative value of alcohol, including alcohol consumption under conditions of zero cost (intensity), maximum expenditure on alcohol (O(max)), persistence in drinking to higher prices (breakpoint) and proportionate price insensitivity (normalized P(max)). Craving was significantly correlated with demand measures at levels ranging from 0.21-0.43. These findings support the potential utility of a behavioral economic approach to understanding the role of environmental stimuli in alcohol-related decision making. Specifically, they suggest that the behavioral economic indices of demand may provide complementary motivational information that is related to though not entirely redundant with measures of subjective craving.

Despite known risks of prenatal nutritional deficiencies and studies documenting increased prevalence of poor dietary intake among nonpregnant alcohol abusers, the nutritional status of heavy drinking pregnant women remains largely unstudied. Animal models have found interactions between prenatal ethanol exposure and micronutrients, such as choline, folate, B12, and iron, and human studies have reported that lower maternal weight and body mass confer increased fetal alcohol-related risk. One hundred and twenty-three heavy drinking Cape Coloured pregnant women and 83 abstaining controls were recruited at their first antenatal clinic visit. At 3 prenatal study visits, each gravida was interviewed about alcohol, smoking, and drug use and weight, height, and arm skinfolds were measured. Dietary intakes of energy, protein, fat, and major micronutrients were assessed from three 24-hour recall interviews. The majority of women gained less than the recommended 0.42 kg/wk during pregnancy. Whereas methamphetamine use was associated with smaller biceps skinfolds, an indicator of body fat, alcohol consumption was not related to any anthropometric indicator. Alcohol was related to higher intake of phosphorus, choline, and vitamins B12 and D. Alcohol, cigarette, and methamphetamine use were related to lower vitamin C intake. Insufficient intake was reported by >85% of women for 10 of 22 key nutrients, and >50% for an additional 3 nutrients. Alcohol consumption during pregnancy was not associated with meaningful changes in diet or anthropometric measures in this population, suggesting that poor nutrition among drinkers does not confound the extensively reported effects of prenatal alcohol exposure on growth and neurobehavior. The poor gestational weight gain and high rates of insufficient intake for several nutrients in both the alcohol-exposed and control groups are also of public health importance.

Consuming excessive amounts of alcohol has the potential to modify an individual's brain and lead to alcohol dependence. Alcohol use leads to 88,000 deaths every year in the U.S. alone and can lead to other health issues including cancers, such as colorectal cancer, and mental health problems. While drinking behavior varies due to environmental factors, genetic factors also contribute to the risk of alcoholism. Certain genes affecting alcohol metabolism and neurotransmitters have been found to contribute to or inhibit the risk. Geneenvironment interactions may also play a role in the susceptibility of alcoholism. With a better understanding of the different components that can contribute to alcoholism, more personalized treatment could cater to the individual. This review discusses the major genetic factors and some small variants in other genes that contribute to alcoholism, as well as considers the gene-environmental interactions.

Full Text Available The author briefly interprets the research – results, referring to the phenomenon of children of alcoholics, especially the psychological and psychopathological characteristics of children of alcoholics in adolescence and young adulthood. The author presents a screening study of adolescents. The sample contains 200 high school students at age 18. The aim of the survey was to discover the relationship between alcohol consumption of parents, PTSD - related psychopathological symptoms and reported life quality of their children. The study confirmed the hypothesis about a substantial correlation between high alcohol consumption of parents, higher psychopathological symptom - expression and lower reported life quality score of their children. Higher PTSD-related symptomatology in children of alcoholics is probably resulted by home violence, which is very often present in family of alcoholics. The article also evaluated the results regarding suicide ideation of children of alcoholics, which is definitely more frequent and more intense than in their peers living in non alcohol – dependent families.

Limited human studies have directly tested the dissociation between wanting and liking with human substance users, a core tenet of the Incentive Sensitisation Theory (IST). The aim of this study is to test the dissociation between wanting and liking in humans across two commonly used licit substances, alcohol and caffeine. The STRAP-R (Sensitivity To Reinforcement of Addictive and other Primary Rewards) questionnaire was administered to 285 alcohol users (mean age=33.30, SD= 8.83) and 134 coffee users (mean age=33.05, SD=8.10) ranging in their levels of substance use to assess wanting and liking. Findings showed that in high risk alcohol users wanting may drive alcohol consumption more so than liking, compared with low risk alcohol users. However, wanting and liking did not significantly dissociate as alcohol consumption increased. These findings partially support IST. Additionally, IST was not supported in coffee users. It is possible that caffeine functions differently at the neurological level compared with alcohol, perhaps explaining the lack of dissociation emerging in coffee users as caffeine use increased. Nevertheless, the current study makes several contributions to IST research. Future studies should focus on utilising the STRAP-R with a clinically dependent sample to test the dissociation between wanting and liking.

Military service is associated with increased rates of heavy drinking. Widely used clinical practices (e.g., motivational interviewing) indicate that addressing both negative and positive drinking consequences is essential to effective treatment. However, research on effectively assessing positive drinking consequences in a clinical population is absent. The current study (1) evaluated the utility of the Positive Drinking Consequences Questionnaire (PDCQ), a measure previously validated in an undergraduate sample, for use with treatment-seeking veterans, and (2) evaluated relationships between positive drinking consequences and alcohol expectancies, pre-treatment alcohol use, and alcohol-related problems. Ninety-seven veterans seeking treatment for alcohol problems completed an anonymous survey (97.9% male; mean age = 49.76[11.40], 67.0% Caucasian). The PDCQ evidenced a single factor latent structure and internal consistency (Cronbach's alpha = .90). Positive drinking consequences and expectancies were related yet distinct constructs. After controlling for demographic factors, experiencing more positive drinking consequences at program intake was associated with heavier pretreatment drinking (ηp(2) = .10, p = .003) and alcohol-related problems (ηp(2) = .18, p alcohol use (ηp(2) = .12, p = .002) and alcohol-related problems (ηp(2) = .11, p = .003) when expectancies also were included in the model. Positive drinking consequences are assessed reliably by the PDCQ in a clinical sample and appear to play an important role in the drinking behavior of veterans seeking alcohol treatment.

BACKGROUND: Moderate to severe psoriasis is associated with increased alcohol intake and excessive mortality from alcohol-related causes. Alcohol biomarkers provide an objective measure of alcohol consumption. Carbohydrate-deficient transferrin (CDT) is the single most sensitive and specific alcohol biomarker. OBJECTIVES: To assess alcohol consumption in a cohort of patients with moderate to severe psoriasis using standard alcohol screening questionnaires and biomarkers. We investigated whether there was an association between alcohol intake, anxiety, depression and disease severity. METHODS: Consecutive patients with chronic plaque psoriasis were recruited and completed a range of anonymized assessments. Psoriasis severity, anxiety and depression, and the impact of psoriasis on quality of life were assessed. Alcohol screening questionnaires were administered. Blood specimens were taken and gamma-glutamyltransferase (gammaGT) and CDT were measured. RESULTS: A total of 135 patients completed the study. Using validated questionnaires, between 22% and 32% had difficulties with alcohol. Seven per cent had CDT > 1.6% indicating a heavy alcohol intake. The Alcohol Use Disorders Identification Test (AUDIT) questionnaire was superior to other validated questionnaires in detecting alcohol misuse. There were no significant associations between measures of excessive alcohol consumption and disease severity. Excessive alcohol intake as measured by the CAGE questionnaire was associated with increased depression (P = 0.001) but other measures of alcohol excess did not correlate with psychological distress. Men had significantly more difficulties with alcohol than women (P < 0.001). CONCLUSION: Alcohol misuse is common in patients with moderate to severe psoriasis. Screening with the AUDIT questionnaire and CDT may allow the identification of patients who are misusing alcohol and allow appropriate intervention.

Numerous investigations indicate a close link between violent behavior, homicide (murder) and alcohol intoxication. With increased frequency of drinking and the chronic consummation of alcohol, the risk of the fatal outcome or homicide and victimization caused by violence is more likely to occur. Studies conducted on convicted murderers suggested that about half of them were under the heavy influence of alcohol at the time of perpetration of murder. The sample in this survey consisted of 177 male offenders which committed criminal act of murder in Croatia from the year of 1990 until 2007 (capital murder and attempted murder). All were assigned for the forensic psychiatric evaluation by the Criminal Justice System (Court of Law) at the Department of Forensic Psychiatry, Neuropsychiatric Hospital, Popovaca, Croatia. For the purpose of this work the sample is divided in two groups of subjects: 1) offenders which were intoxicated at the time of murder and committed offence on intoxicated victim 2) offenders who were sober and committed offence on sober victims. Groups are compared according to the variables of crime and history of alcohol abuse. On the basis of obtained results we can conclude that there are significant differences in relation to the variables and modalities of criminal offence between two groups of offenders and victims. We could conclude that alcohol intoxication in offenders and victims at the time of murder could strongly affect the modalities of murder.

The negative consequences of chronic alcohol abuse are well known, but heavy episodic consumption ("binge drinking") is also associated with significant personal and societal harms. Aggressive tendencies are increased after alcohol but the mechanisms underlying these changes are not fully understood. While effects on behavioural control are likely to be important, other effects may be involved given the widespread action of alcohol. Altered processing of social signals is associated with changes in social behaviours, including aggression, but until recently there has been little research investigating the effects of acute alcohol consumption on these outcomes. Recent work investigating the effects of acute alcohol on emotional face processing has suggested reduced sensitivity to submissive signals (sad faces) and increased perceptual bias towards provocative signals (angry faces) after alcohol consumption, which may play a role in alcohol-related aggression. Here we discuss a putative mechanism that may explain how alcohol consumption influences emotional processing and subsequent aggressive responding, via disruption of OFC-amygdala connectivity. While the importance of emotional processing on social behaviours is well established, research into acute alcohol consumption and emotional processing is still in its infancy. Further research is needed and we outline a research agenda to address gaps in the literature. PMID:24920135

Every study of exploration capabilities since the Apollo Program has recommended the renewal of a heavy lift launch capability for the United States. NASA is aggressively pursuing that capability. This paper will discuss several aspects of that effort and the potential uses for that heavy lift capability. The need for heavy lift was cited most recent in the findings of the Review of U.S. Human Space Flight Plans Committee. Combined with considerations of launch availability and on-orbit operations, the Committee finds that exploration will benefit from the availability of a heavy-lift vehicle, the report said. In addition, heavy lift would enable the launching of large scientific observatories and more capable deep-space missions. It may also provide benefit in national security applications. The most recent focus of NASA s heavy lift effort is the Ares V cargo launch vehicle, which is part of the Constellation Program architecture for human exploration beyond low Earth orbit (LEO). The most recent point-of-departure configuration of the Ares V was approved during the Lunar Capabilities concept Review (LCCR) in 2008. The Ares V first stage propulsion system consists of a core stage powered by six commercial liquid hydrogen/liquid oxygen (LH2/LOX) RS-68 engines, flanked by two 5.5-segment solid rocket boosters (SRBs) based on the 5-segment Ares I first stage. The boosters use the same Polybutadiene Acrylonitrile (PBAN) propellant as the Space Shuttle. Atop the core stage is the Earth departure stage (EDS), powered by a single J-2X upper stage engine based on the Ares I upper stage engine. The 33-foot-diameter payload shroud can enclose a lunar lander, scientific instruments, or other payloads. Since LCCR, NASA has continued to refine the design through several successive internal design cycles. In addition, NASA has worked to quantify the broad national consensus for heavy lift in ways that, to the extent possible, meet the needs of the user community.

Background Concise, accurate measures of maternal prenatal alcohol use are needed to better understand fetal alcohol spectrum disorders (FASD). Methods Measures of drinking by mothers of children with specific FASD diagnoses and mothers of randomly-selected controls are compared and also correlated with physical and cognitive/behavioral outcomes. Results Measures of maternal alcohol use can differentiate maternal drinking associated with FASD from that of controls and some from mothers of alcohol-exposed normals. Six variables that combine quantity and frequency concepts distinguish mothers of FASD children from normal controls. Alcohol use variables, when applied to each trimester and three months prior to pregnancy, provide insight on critical timing of exposure as well. Measures of drinking, especially bingeing, correlate significantly with increased child dysmorphology and negative cognitive/behavioral outcomes in children, especially low non-verbal IQ, poor attention, and behavioral problems. Logistic regression links (palcohol consumption both within and between diagnostic groupings of mothers bearing children diagnosed within the FASD continuum. Drinking measures are empirically identified and correlated with specific child outcomes. Alcohol use, especially heavy use, should be avoided throughout pregnancy. PMID:23932841
This report begins with a historical sketch of heavy water. The report next assesses the nonproliferation implications of the use of heavy water-moderated power reactors; several different reactor types are discussed, but the focus is on the natural uranium, on-power fueled, pressure tube reactor CANDU. The need for and development of on-power fueling safeguards is discussed. Also considered is the use of heavy water in plutonium production reactors as well as the broader issue of the relative nuclear leverage that suppliers can bring to bear on countries with natural uranium-fueled reactors as compared to those using enriched designs. The final chapter reviews heavy water production methods and analyzes the difficulties involved in implementing these on both a large and a small scale. It concludes with an overview of proprietary and nonproliferation constraints on heavy water technology transfer

Full Text Available OBJECTIVES: The current study set out to investigate alcohol availability in a densely populated, residential area of suburban São Paulo associated with high levels of social deprivation and violence. Gun-related deaths and a heavy concentration of alcohol outlets are notable features of the area surveyed. Given the strong evidence for a link between alcohol availability and a number of alcohol-related problems, including violent crime, measures designed to reduce accessibility have become a favored choice for alcohol prevention programs in recent years. METHODS: The interviewers were 24 residents of the area who were trained for the study. It was selected an area of nineteen streets, covering a total distance of 3.7 km. A profile of each alcohol outlet available on the area was recorded. RESULTS: One hundred and seven alcohol outlets were recorded. The number of other properties in the same area was counted at 1,202. Two measures of outlet density may thus be calculated: the number of outlets per kilometer of roadway (29 outlets/km; and the proportion of all properties that sold alcohol (1 in 12. CONCLUSIONS: The results of this study is compared with others which are mainly from developed countries and shown that the area studied have the highest density of alcohol outlet density ever recorded in the medical literature. The implication of this data related to the violence of the region is discussed. By generating a profile of alcohol sales and selling points, it was hoped to gain a better understanding of alcohol access issues within the sample area. Future alcohol prevention policy would be well served by such knowledge.
idade de início de consumo de tabaco e/ou álcool e a intensidade de uso de tabaco. Uso de maconha e idade de início do consumo foram as variáveis de desfecho. Para a análise dos dados se utilizou regressão de Poisson e regressão de Weibull. RESULTADOS: Os escolares apresentaram alta prevalência de consumo de tabaco, álcool maconha (77%, 79% e 23%, respectivamente. O consumo de tabaco na presença de consumo de álcool foi um fator de risco de uso de maconha (RP=10,4; IC 95%: 8,9;12,2. O início tardio de consumo de tabaco (HR=0,85; IC 95%: 0,84;0,86 e álcool (HR=0,90; IC 95%: 0,89;0,91 resultou ser um fator protetor do uso de maconha. A probabilidade de consumo de maconha foi maior naqueles que fumavam diariamente ou quase, em relação àqueles que fumavam somente aos fins de semana (RP=3,11; IC 95%: 2,96;3,26 vs. RP=1,70; IC 95%: 1,58;1,83. CONCLUSÕES: O risco de consumo de maconha se associou significativamente à idade de início de consumo de tabaco, à freqüência de consumo de tabaco e ao consumo simultâneo de álcool. As estratégias de prevenção deveriam proteger os escolares do consumo precoce de tabaco.OBJECTIVE: To assess the relationship between early tobacco and alcohol use and the risk of marijuana consumption among schoolchildren. METHODS: A cross-sectional study comprising data from the Fourth National Study on Drug Use in the Chilean School Population (2001. There were studied 54,001 schoolchildren aged between eight and 20 years. Predictors were self-reported tobacco and alcohol use (ever users, age at initiation of tobacco and/or alcohol use, and intensity of tobacco use. The study outcome was self-reported marijuana use (ever users versus never users and age at initiation of marijuana use. Poisson regression and Weibull regression were used for data analysis. RESULTS: Lifetime prevalence of tobacco use was high: 77%, alcohol 79%, and marijuana 23%. Tobacco consumption increased the likelihood of marijuana use (PR=10.4; 95% CI: 8

The objective of this study was to assess the oral health status of users of illicit drugs such as marijuana and cocaine/crack and compare it with individuals not using these chemical substances. Questionnaires were applied to 35 illicit drugs users to gather information on demographic status, general health, and use of drugs. Then, a clinical assessment of the oral health condition was performed to collect data on decayed, missing and filled teeth (DMFT) index, salivary flow rate (SFR), and mucosal lesions. The control group was composed of 35 non-illicit drug users. In the experimental group, 91.43% were males, 80% were smokers, and 42.85% were alcoholics. Cocaine was the most common drug used (77.15%), followed by marijuana (68.6%), and crack (51.4%). The average DMFT index was 9.8 and the SFR was reduced in 60% of subjects. Mucosal alterations were detected, but no potentially malignant disorders or oral cancer were diagnosed. Compared to control group, significantly higher values for gender (40%, p = 0.0001), smoking (22.86%) and heavy drinking (5.7%) habits (p = 0.0001), SFR (31.4%; p = 0.0308), and oral lesions (p = 0.0488) were found for the experimental group, although significantly higher values were found in the control group for DMFT index (p = 0.0148). It can be concluded that the use of illicit drugs contributed to an increased prevalence of oral mucosa lesions. In addition, a decline on SFR and a reduced DMFT index was observed for illicit drug users.

From the earliest times to the present, alcohol has evolved as part of life and culture. For most adults, moderate alcohol use is harmless, however, it lies at one end of a range that moves through alcohol abuse to alcohol addiction. Alcohol addiction is a serious and chronic psychiatric disorder that, on top of its heavy consequences on health, also brings significant social and economic losses to individuals and society at large. Pharmacotherapy of alcohol addiction exists, but its effectiveness varies significantly among individuals. Genomic and nongenomic factors are significant contributors to interindividual variation in the clinical presentation of alcohol problems and the response to a given treatment. In addition, emerging evidence suggests pharmacoepigenomics of alcohol addiction as a novel promising area for improvement of alcohol addiction management.

Several lines of evidence indicate that chronic alcohol use disorder leads to increased susceptibility to several viral and bacterial infections, whereas moderate alcohol consumption decreases the incidence of colds and improves immune responses to some pathogens. In line with these observations, we recently showed that heavy ethanol intake (average blood ethanol concentrations > 80 mg/dl) suppressed, whereas moderate alcohol consumption (blood ethanol concentrations consumption. To uncover the molecular basis for impaired immunity with heavy alcohol consumption and enhanced immune response with moderate alcohol consumption, we performed a transcriptome analysis using PBMCs isolated on day 7 post-modified vaccinia Ankara vaccination, the earliest time point at which we detected differences in T cell and Ab responses. Overall, chronic heavy alcohol consumption reduced the expression of immune genes involved in response to infection and wound healing and increased the expression of genes associated with the development of lung inflammatory disease and cancer. In contrast, chronic moderate alcohol consumption upregulated the expression of genes involved in immune response and reduced the expression of genes involved in cancer. To uncover mechanisms underlying the alterations in PBMC transcriptomes, we profiled the expression of microRNAs within the same samples. Chronic heavy ethanol consumption altered the levels of several microRNAs involved in cancer and immunity and known to regulate the expression of mRNAs differentially expressed in our data set.

The relationships between involvement in sports and alcohol consumption appear to be complex in the alcohol literature. In this study we aimed to examine this link among French students, taking into account their sports characteristics. We also examined variations in alcohol use among sport sciences students between 2002 and 2006, and the difference in alcohol use and heavy episodic drinking among sport sciences, law and pharmacy students. repeated survey; cross-sectional study; self-questionnaire survey; French (south-east France) sport sciences (n=693), law (n=325) and pharmacy (n=338) students (females=58%). In 2002, 38% of the male sport sciences students reported repeated heavy episodic drinking, and this proportion has risen to 48% in 2006 (psport sciences students were less likely to report repeated heavy episodic drinking (part were negatively related to heavy episodic drinking (psport in a formal context, team sports, and competitive participation at a departmental or regional level represented risk factors (psport was a protective factor among females (psport practised to examine the link between sport participation and alcohol consumption. The normative context of peer socialization among competitive and team sports participants seemed to play a role in alcohol use. Further studies are needed to confirm the role of this putative factor.

Previous studies on part-time work and alcohol use suggest that teenagers who work longer hours drink more heavily. The purpose of this study was to investigate whether family- and community-level factors moderate the relationship between part-time work hours and heavy episodic drinking. Data were drawn from the Canadian Community Health Survey, a cross-sectional study of a nationally representative sample of Canadians. The survey included 8,080 respondents 15-19 years of age who reported work hours and frequency of heavy episodic drinking over the past 12 months. These respondents were located in 136 counties or municipalities across Canada. On average, work hours were positively associated with the frequency of heavy drinking by teenagers in the past 12 months. At the community level, the proportion of teenagers in each community drinking any alcohol was independently and positively associated with respondents' frequency of heavy drinking. In terms of moderating effects, we found that the work hours-drinking association was weaker among youth from low socioeconomic status families. Examination of community-level factors indicated that longer work hours were more strongly associated with heavy episodic drinking in communities with high rates of teen alcohol abstinence. Although the cross-sectional data prohibit any firm conclusions on how family and community factors influence the work-alcohol use relationship, these data suggest that interventions to reduce heavy episodic drinking among teens should address the broader environmental as well as the individual determinants.

Alcohol is widely consumed; however, excessive use creates serious physical, psychological and social problems and contributes to the pathogenesis of many diseases. Alcohol use disorders (that is, alcohol dependence and alcohol abuse) are maladaptive patterns of excessive drinking that lead to serious problems. Abundant evidence indicates that alcohol dependence (alcoholism) is a complex genetic disease, with variations in a large number of genes affecting a person's risk of alcoholism. Some of these genes have been identified, including two genes involved in the metabolism of alcohol (ADH1B and ALDH2) that have the strongest known affects on the risk of alcoholism. Studies continue to reveal other genes in which variants affect the risk of alcoholism or related traits, including GABRA2, CHRM2, KCNJ6 and AUTS2. As more variants are analysed and studies are combined for meta-analysis to achieve increased sample sizes, an improved picture of the many genes and pathways that affect the risk of alcoholism will be possible.

Synthesis techniques for molybdenum (6) alcoholates of MoO(OR) 4 (1) and MoO 2 (OR) 2 (2) series by means of exchange interaction of corresponding oxychloride with MOR (M=Li, Na) are obtained. These techniques have allowed to prepare 1(R=Me, Et, i-Pr) and 2(R=Me, Et) with 70-98 % yield. Methylates are also prepared at ether interchange of ethylates by methyl alcohol. Metal anode oxidation in corresponding alcohol may be used for 1 synthesis. Physicochemical properties of both series alcoholates, solubility in alcohols in particular, depend on their formation conditions coordination polymerism. Alcoholates of 1 are rather unstable and tend to decomposition up to 2 and ether. It is suggested to introduce NaOR microquantities to stabilize those alcoholates

Light to moderate alcohol intake is known to have cardioprotective properties; however, the magnitude of protection depends on other factors and may be confined to some subsets of the population. This review focuses on factors that modify the relationship between alcohol and coronary heart disease...... (CHD). The cardioprotective effect of alcohol seems to be larger among middle-aged and elderly adults than among young adults, who do not have a net beneficial effect of a light to moderate alcohol intake in terms of reduced all-cause mortality. The levels of alcohol at which the risk of CHD is lowest...... and the levels of alcohol at which the risk of CHD exceeds the risk among abstainers are lower for women than for men. The pattern of drinking seems important for the apparent cardioprotective effect of alcohol, and the risk of CHD is generally lower for steady versus binge drinking. Finally, there is some...
A significant segment of the Latino migrant worker population in the United States is at high risk for alcohol abuse and related risk behaviors. Information about the prevalence of alcohol use and abuse and its association with sociodemographic and psychological variables is needed for designing effective intervention prevention strategies. Cross-sectional data were drawn from a baseline assessment that was part of a randomized controlled trial of 278 Latino migrant workers (LMWs) conducted between 2008 and 2010. About one-third (32%) of participants engaged in heavy drinking in the past 30 days prior to baseline interview. More females than males reported no alcohol use in the past 30 days (53.5% vs. 20.5%). On the other hand, more males reported drinking every day or nearly (25.2% vs. 7.1%). Five factors-gender, country of origin, relationship status, living arrangements, and acculturation-were significantly associated with frequency of alcohol consumption. Multivariate analyses indicated that gender, country of origin, education attainment, relationship status, living arrangement, living with children, length of stay in the US, religious beliefs, acculturation, and depression were associated with frequent heavy drinking, alcohol abuse/dependence, and unprotected sex under the influence of alcohol. There is significant variation in alcohol use among Latino migrant workers. Although a substantial proportion of this population abstains from alcohol, an equally substantial proportion report levels of alcohol use that pose significant risk. More research is needed to better understand drinking patterns in this community in order to design prevention strategies specifically tailored for this population.

The notion of risk reduction applies to all uses, drinking of alcohol and smoking including, addictions without drugs likewise. With regard to drugs, mentalities change. We now talk more of risks than fault or deviance. Following, collaboration between health professionals and users, sharing and cooperation are the conditions necessary to develop a modern humanist and social addictology approach.

Existing research on parental supply of alcohol analyses the effects of self-reported parental supply on adolescent drinking using individual level data. This study examined the contextual effect of parental supply of alcohol on adolescent alcohol use by examining the association between the prevalence of parental supply in each Australian state and adolescent alcohol use using a multilevel analytic framework. Adolescent samples (Age: 12-17) were drawn from the four National Drug Strategy Household Surveys (2004, 2007, 2010 and 2013; N = 6803). The prevalence of parental supply of alcohol, defined as the weighted percentage of sample who reported obtaining alcohol from their parents, was estimated in each state and territory across the four surveys. Three multilevel logistic regressions were used to examine the contextual effects of parental supply prevalence on adolescents' alcohol use in the past 12 months, weekly drinking and heavy drinking. Overall, adolescents' rates of past 12 months alcohol use, heavy drinking and weekly drinking between 2004 and 2013 were 40.1, 14.4 and 6.4% respectively. The prevalence of parental supply was significantly associated with past 12 months alcohol use (OR = 1.06, p supply. A high prevalence of parental supply in a region was associated with heavier adolescent drinking, regardless of whether adolescents primarily obtained their alcohol from their own parents.
This lecture deals with some of the more important physical characteristics of relativistic heavy ions and their measurement, with beam delivery and beam monitoring, and with conventional radiation dosimetry as used in the operation of the BEVALAC biomedical facility for high energy heavy ions (Lyman and Howard, 1977; BEVALAC, 1977). Even so, many fundamental aspects of the interaction of relativistic heavy ions with matter, including important atomic physics and radiation chemical considerations, are not discussed beyond the reminder that such additional understanding is required before an adequte perspective of the problem can be attained

In Australia, the immediate post-school period (known as 'Schoolies') is associated with heavy drinking and high levels of alcohol-related harm. This study investigated students' intended alcohol consumption during Schoolies to inform interventions to reduce alcohol-related harm among this group. An online survey was administered to students in their senior year of schooling. Included items related to intended daily alcohol consumption during Schoolies, amount of money intended to be spent on alcohol over the Schoolies period, and past drinking behaviour. On average, participants (n=187) anticipated that they would consume eight standard drinks per day, which is substantially higher than the recommended maximum of no more than four drinks on a single occasion. Participants intended to spend an average of A$131 on alcohol over the Schoolies period. Although higher than national guidelines, intended alcohol consumption was considerably lower than has been previously documented during Schoolies events. The substantial amounts of money expected to be spent during Schoolies suggest this group has adequate spending power to constitute an attractive target market for those offering alternative activities that are associated with lower levels of alcohol-related harm.
Full Text Available Aims - The high price of alcohol in the Nordic countries has been a long-standing policy to curb consumption, which has led consumers to importing alcohol from countries with lower prices. This paper seeks to develop a profile of alcohol importers in four Nordic countries. Methods - Cross-sectional data from general population surveys in Denmark (2003-2006, Norway (2004, Sweden (2003-2006 and Finland (2005-2006 were analysed by multiple logistic and linear regression. Independent variables included region, socio-demographics, drinking indicators and alcohol-related problems. Outcome variables were importer status and amount of imported alcohol. Results - People living in regions close to countries with lower alcohol prices were more often importers and imported higher amounts than people living in other regions. Higher educated persons were more likely to be importers, but the amounts imported were smaller than those by people with lower education. Persons with higher incomes were also more likely to be importers and they also imported larger amounts than people with lower incomes. In Sweden and Denmark regional differences of importer rates were more pronounced for persons of lower incomes. Age, risky single-occasion drinking, risky drinking and alcohol problems were positively related to the amounts of imported alcohol. Conclusions - Private importers in the Nordic countries are an integrated yet heavy drinking segment of society and do not appear to be located on the fringes of society
