Abstract
BACKGROUND Alcohol use disorders (AUD) are a common cause of poor treatment outcomes among people with HIV (PWH). In Malawi, routine screening for AUD among PWH is unavailable. We piloted the utility of the Alcohol Use Disorders Identification Test (AUDIT) in screening for AUD among PWH and assessed its adoption, acceptability and fidelity in HIV clinics in Malawi. METHODS We implemented the AUDIT tool at Mchinji, Kapiri and Kochirira hospitals in Mchinji District between April and May 2021. AUD were defined and classified based on WHO classification as low-risk, harmful/hazardous alcohol use or alcohol dependence. We calculated the prevalence of AUD, the proportion of providers who conducted AUD screening (adoption) and the proportion of providers who conducted AUD screening as intended (fidelity) and compared between clinics. Lastly, we assessed acceptability through a survey among providers. RESULTS Out of 2036 PWH, 875 (43%) were screened for AUD and 51% were female, mean age was 41 years (SD±12) and 338 (39%) had AUD. Adoption was highest at Mchinji (58%) compared to Kapiri (31%) and Kochiria (29%) (P<0.001). Overall Fidelity was 96%, and it was highest at Kapiri (99%) compared to Mchinji (95%) and Kochirira (98%) (P=0.01). AUD screening with AUDIT was highly acceptable as most providers agreed or completely agreed that the AUDIT was important (100%), easy to use (96%), satisfactory (96%), agreed to continue use (61%) and recommended it for other facilities in the district (100%). CONCLUSION AUD were common among PWH. While the adoption of AUDIT for AUD screening was moderate, acceptability and fidelity were high. The impact of AUD on HIV treatment outcomes needs to be assessed to determine the role of routine AUD screening in HIV clinics in Malawi.

Abstract
BACKGROUND The Kilimanjaro region has one of the highest levels of reported alcohol intake per capita in Tanzania. Age at first drink has been found to be associated with alcohol problems in adulthood, but there is less information on the age of first drink in the Kilimanjaro region and its associations with alcohol-related consequences later in life. Furthermore, local alcohol cost and availability may influence the prevalence of alcohol use and alcohol use disorders. METHODS Data on the age of first drink, alcohol use disorder identification tool (AUDIT), number and type of alcohol consequences (DrInC), and perceived alcohol at low cost and high availability for children and adolescents were collected from an alcohol and health behavior survey of injury patients (N = 242) in Moshi, Tanzania. Generalized linear models were used to test age at first drink, perceived alcohol cost and availability, and their association with the AUDIT and DrInC scores, and current alcohol use, respectively. RESULTS Consuming alcohol before age 18 was significantly associated with higher AUDIT and DrInC scores, with odds ratios of 1.22 (CI: 1.004, 1.47) and 1.72 (CI: 1.11, 2.63), respectively. Female gender is strongly associated with less alcohol use and alcohol consequences, represented by an odds ratio of 3.70 (CI: 1.72, 8.33) for an AUDIT score above 8 and an odds ratio of 3.84 (CI: 2.13, 6.67) with the DrInC score. Perceived high availability of alcohol for children is significantly related to higher alcohol use quantity, with the odds ratio of 1.6 (CI: 1.17, 2.20). CONCLUSIONS The first use of alcohol before the age of 18 is associated with higher alcohol use and alcohol-related adverse consequences. In Tanzania, age at first drink is an important target for interventions aiming to prevent negative alcohol-related consequences later in life.

Abstract
BACKGROUND Distinguishing the impacts of neighborhood income and off-premise alcohol outlet density on alcohol use has proven difficult, particularly given the conflation of these measures across neighborhood areas. We explicitly test for differential effects related to individual and area income and outlet densities on alcohol use and alcohol use disorders (AUDs) by implementing a stratified microecological sample. METHODS The East Bay Neighborhoods Study included a survey of 984 residents of 72 microenvironments within a geographically contiguous 6-city area in California and Systematic social observations of each site. The sites included 18 areas in each of 4 strata (high/low median household income and off-premise outlet density). We assessed 4 outcomes: 28-day drinking frequency, average quantity of alcohol consumed per drinking occasion, 28-day drinking volume, and Alcohol Use Disorders Identification Test (AUDIT) score. We used zero-inflated negative binomial regression with standard errors adjusted for site clusters to relate drinking measures to individual-level age, race/ethnicity, gender, marital status, education, and income, and neighborhood indicators of site strata, physical disorder, and physical decay. An interaction term was tested representing site-level by individual-level income. RESULTS Living in a high-income site, regardless of off-premise alcohol outlet density, was associated with more frequent drinking and higher alcohol dependence/problems. Both individual-level income and site-level income were related to greater frequencies of use, but lower income drinkers in high-income areas drank more than comparable drinkers in low-income areas. Study participants living in high-density off-premise alcohol outlet sites drank less frequently but did not differ in terms of either AUDIT scores or heavy drinking from participants living in low-density sites. CONCLUSIONS Using a stratified microecological sampling design, we were able to directly assess statistical associations of off-premise outlet density and neighborhood median household income with patterns of drinking and AUDs. Caution should be used interpreting prior study findings linking off-premise outlet densities to drinking.

Abstract
BACKGROUND Chronic alcohol use results in changes to stress biology and autonomic arousal contributing to acute alcohol withdrawal symptoms, neuroendocrine tolerance of the hypothalamic-pituitary-adrenal axis responses, high stress-induced craving, and risk of alcohol relapse. Thus, stress coping and recovery from alcohol during early abstinence may be jeopardized by such stress system dysfunction. Significant preclinical evidence suggests that noradrenergic disruption may contribute to these alcohol-related stress arousal changes and that alpha-1 adrenergic antagonists, such as prazosin, may normalize these stress system adaptations and reduce alcohol intake. Thus, we hypothesized that prazosin would reduce stress-induced craving and improve neuroendocrine and autonomic response to stress and alcohol cue exposure during early abstinence. We secondarily also assessed the role of lifetime anxiety disorders on these prazosin effects. METHODS Forty inpatient treatment-seeking alcohol-dependent individuals were randomly assigned to receive placebo (n = 18) or 16 mg/d, T.I.D., prazosin (n = 22) in a double-blind manner, titrated over 2 weeks. In weeks 3 to 4 after achieving full dose, patients were exposed to 3 5-minute personalized guided imagery conditions (stress cue, alcohol cue, neutral/relaxing cue), on 3 consecutive days in a random, counterbalanced order. Alcohol craving, anxiety, heart rate, cortisol, and adrenocorticotropic hormone (ACTH) levels were assessed at baseline, following imagery and at repeated recovery timepoints. RESULTS Prazosin reduced stress cue-induced alcohol craving (p < 0.05) and stress- and alcohol cue-induced anxiety (p < 0.05) and increased heart rate responses in all imagery conditions (p < 0.05). Prazosin lowered basal cortisol and ACTH (p's < 0.05) and attenuated stress cue-induced rises in cortisol (p < 0.05) versus placebo. Finally, in those without lifetime anxiety disorder, the placebo group showed stress- and alcohol cue-induced increases in cortisol (p's < 0.05), while the prazosin group did not. CONCLUSIONS Prazosin may attenuate stress cue-induced alcohol craving and anxiety during early abstinence while improving adrenergic and stress system function, effects which are independent of a history of lifetime anxiety disorders.

Abstract
BACKGROUND High frequency of alcohol use among people living with HIV (PLWH) warrants careful assessment and screening to better understand its impact on HIV disease progression and development of comorbidities. Due to the limitations of the tools used to measure alcohol use, the links to health consequences are not fully understood. METHODS We completed a cross-sectional analysis to examine the prevalence of alcohol consumption using multiple alcohol assessment tools and their correlation and consistency in a cohort of PLWH (N = 365) enrolled in the New Orleans Alcohol Use in HIV (NOAH) Study. Alcohol use was assessed with the Alcohol Use Disorders Identification Test (AUDIT), timeline followback (TLFB) Calendar, lifetime drinking history, Alcohol and Drug Addiction Severity Index, and blood levels of phosphatidylethanol (PEth). Spearman's correlations were estimated for continuous measures of alcohol consumption; Wilcoxon rank-sum tests were used to compare means; and logistic regression was used to estimate odds of alcohol use by demographic characteristics. RESULTS Self-report of current alcohol use varied from 58.9 to 73.7% depending on the assessment. All the self-reported alcohol measures showed statistically significant correlations with the biological marker PEth. The highest correlation was with TLFB grams (r = 0.67, p < 0.001). Using TLFB, 73.7% of the cohort reported using alcohol in the last 30 days, and 61.6% had a positive PEth value. The prevalence of risky drinkers, meeting the TLFB > 3 (women) or >4 (men) drinks/day or>7 (women) or>14 (men) drinks/week, was 49.0%. Medium-risk drinking defined as an AUDIT score ≥ 8 was reported in 40.3%, and high-risk drinkers/probable AUD (AUDIT score ≥ 16) was met by 17.0% of the cohort. CONCLUSIONS Our results demonstrate the importance of comprehensive assessments for alcohol use, including self-report via multiple assessment tools administered by trained staff, as well as the addition of biomarkers for improved classification of subjects into different drinking categories.

Abstract
OBJECTIVE The authors examined the efficacy of valproate to reduce relapse to heavy drinking among veterans with alcohol use disorder (AUD) and neuropsychiatric comorbidities and whether antecedent traumatic brain injury (TBI) or posttraumatic stress disorder (PTSD) affected treatment response. METHODS Participants were male veterans 18-60 years old with an AUD and no other substance use besides nicotine or cannabis. Sixty-two patients were randomly assigned to receive either valproate or naltrexone. Participants were evaluated at baseline and followed weekly for 24 weeks. All participants received standardized psychosocial interventions as well as treatment for coexistent psychiatric conditions. RESULTS During the follow-up period, nine study subjects in the naltrexone group and 14 in the valproate group relapsed to heavy drinking, but the difference did not reach statistical significance. Participants with a history of moderate to severe TBI were more likely to relapse to heavy drinking compared with those with no TBI (hazard ratio=4.834, 95% CI=1.103-21.194, p=0.033). PTSD status did not significantly affect outcome. CONCLUSIONS Intensive outpatient programs are efficacious alternatives to treat AUD in veterans, although the role of pharmacological treatment is not completely elucidated. Glutamatergic agents appear to be less effective than opiate antagonists to prevent relapse to heavy drinking and to increase cumulative abstinence. Future studies should examine novel pharmacological and nonpharmacological options.

Abstract
OBJECTIVES The aims were to estimate the association between intelligence measured in young adulthood and risk of alcohol use disorders (AUD) in men and to investigate the potential modification of this association by psychiatric disorders, parental AUD and parental psychiatric disorders. DESIGN Prospective cohort study based on a linkage of intelligence test scores from draft board examinations and register data on AUD diagnoses during 36 years of follow-up. SETTING Denmark. PARTICIPANTS 3287 Danish men from the Copenhagen Perinatal Cohort (born 1959-1961) who appeared before the draft board at a mean age of 18.7 years. PRIMARY OUTCOME MEASURE First registration with AUD during follow-up was the primary outcome. Information on AUD was based on diagnoses retrieved from national hospital and outpatient treatment registers, defined according to the International Classification of Diseases. RESULTS 361 (11.0%) men were registered with AUD during follow-up. Low intelligence scores were associated with increased odds of AUD adjusting for parental AUD, parental psychiatric disorders, maternal smoking during pregnancy, birth weight, maternal age at birth, parity and childhood socioeconomic position (OR per SD decrease in intelligence=1.69, 95% CI 1.49 to 1.92). Separate analyses indicated significant interaction (p<0.001) between intelligence and psychiatric disorders. The adjusted OR per SD decrease in intelligence score was 2.04 (95% CI 1.67 to 2.49) in men without other psychiatric disorders whereas the OR was 1.21 (95% CI 1.01 to 1.46) in men with other psychiatric disorders. No interaction was found between intelligence and parental AUD or between intelligence and parental psychiatric disorders. CONCLUSIONS The association between intelligence in young adulthood and AUD is modified by other psychiatric disorders as low intelligence is primarily a risk factor for men without other psychiatric disorders. Future studies should take other psychiatric disorders into account when investigating associations between intelligence and AUD.

Abstract
BACKGROUND Driving under the influence (DUI) programs are a unique setting to reduce disparities in treatment access to those who may not otherwise access treatment. Providing evidence-based therapy in these programs may help prevent DUI recidivism. METHODS We conducted a randomized clinical trial of 312 participants enrolled in 1 of 3 DUI programs in California. Participants were 21 and older with a first-time DUI offense who screened positive for at-risk drinking in the past year. Participants were randomly assigned to a 12-session manualized cognitive behavioral therapy (CBT) or usual care (UC) group and then surveyed 4 and 10 months later. We conducted intent-to-treat analyses to test the hypothesis that participants receiving CBT would report reduced impaired driving, alcohol consumption (drinks per week, abstinence, and binge drinking), and alcohol-related negative consequences. We also explored whether race/ethnicity and gender moderated CBT findings. RESULTS Participants were 72.3% male and 51.7% Hispanic, with an average age of 33.2 (SD = 12.4). Relative to UC, participants receiving CBT had lower odds of driving after drinking at the 4- and 10-month follow-ups compared to participants receiving UC (odds ratio [OR] = 0.37, p = 0.032, and OR = 0.29, p = 0.065, respectively). This intervention effect was more pronounced for females at 10-month follow-up. The remaining 4 outcomes did not significantly differ between UC versus CBT at 4- and 10-month follow-ups. Participants in both UC and CBT reported significant within-group reductions in 2 of 5 outcomes, binge drinking and alcohol-related consequences, at 10-month follow-up (p < 0.001). CONCLUSIONS In the short-term, individuals receiving CBT reported significantly lower rates of repeated DUI than individuals receiving UC, which may suggest that learning cognitive behavioral strategies to prevent impaired driving may be useful in achieving short-term reductions in impaired driving.

Abstract
Background The Alcohol Use Disorders Identification Test (AUDIT) was developed for use in primary health care settings to identify hazardous and harmful patterns of alcohol consumption, and is often used to screen for alcohol use disorders (AUDs). This study examined the AUDIT as a screening tool for AUDs. Methods A systematic literature search was performed of electronic bibliographic databases (CINAHL, Embase, ERIC, MEDLINE, PsycINFO, Scopus, and Web of Science) without language or geographic restrictions for original quantitative studies published before September 1, 2018, that assess the AUDIT's ability to screen for AUDs. Random‐effects meta‐regression models were constructed by sex to assess the potential determinants of the AUDIT's specificity and sensitivity. From these models and ecological data from the Global Information System on Alcohol and Health, the true‐ and false‐positive and true‐ and false‐negative proportions were determined. The number of people needed to be screened to treat 1 individual with an AUD was estimated for all countries globally where AUD data exist, using a specificity of 0.95. Results A total of 36 studies met inclusion criteria for the meta‐regression. The AUDIT score cut‐point was significantly associated with sensitivity and specificity. Standard drink size was found to affect the sensitivity and specificity of the AUDIT for men, but not among women. The AUDIT performs less well in identifying women compared to men, and countries with a low prevalence of AUDs have higher false‐positive rates compared to countries with a higher AUD prevalence. Conclusions The AUDIT does not perform well as a screening tool for identifying individuals with an AUD, especially in countries and among populations with a low AUD prevalence (e.g., among women), and thus should not be used for this purpose.

Abstract
Alcohol consumption is increasing in the United States, as is alcohol-attributable mortality. Historically, men have had higher rates of alcohol consumption than women, though evidence for birth cohort effects on gender differences in alcohol consumption and alcohol-related harm suggests that gender differences may be diminishing. We review studies using U.S. national data that examined time trends in alcohol consumption and alcohol-related harm since 2008. Utilizing a historical-developmental perspective, here we synthesize and integrate the literature on birth cohort effects from varying developmental periods (i.e., adolescence, young adulthood, middle adulthood, and late adulthood), with a focus on gender differences in alcohol consumption. Findings suggest that recent trends in gender differences in alcohol outcomes are heterogeneous by developmental stage. Among adolescents and young adults, both males and females are rapidly decreasing alcohol consumption, binge and high-intensity drinking, and alcohol-related outcomes, with gender rates converging because males are decreasing consumption faster than females. This pattern does not hold among adults, however. In middle adulthood, consumption, binge drinking, and alcohol-related harms are increasing, driven largely by increases among women in their 30s and 40s. The trend of increases in consumption that are faster for women than for men appears to continue into older adult years (60 and older) across several studies. We conclude by addressing remaining gaps in the literature and offering directions for future research.

Abstract
Few studies have examined group cohesion and climate in the substance use disorder treatment literature. We examined whether group cohesion and climate are associated with increased self-efficacy outcomes and reduced drinks per week, binge drinking and DUI behaviors, in a sample of individuals with a first-time DUI receiving either cognitive behavioral therapy (CBT) or usual care. Additionally, we examined whether CBT moderates these relationships. Group measures and drinking outcomes were not significantly associated. This study is the first to provide an in-depth analysis on group processes in DUI settings, and as such, provides important insights into how group processes may differ in a mandated DUI context.

Abstract
BACKGROUND Some authors have pointed out the usefulness of the levels of substance use disorder (SUD) as a treatment outcome. However, in order to use this variable as an outcome measure, its impact needs to be addressed within a clinical context. The aim of this study was to analyze the sensitivity of SUD levels as a measure for detecting reliable changes and to make a comparison between the changes in SUD levels detected when using the number of criteria fulfilled and when using the reliable change index (RCI). METHODS The sample consisted of 206 (106 in follow-up) patients diagnosed with abuse/dependence on alcohol and cocaine, according to DSM-IV criteria. The Substance Dependence Severity Scale for DSM-5 was used to determine current alcohol use disorder (AUD) and cocaine use disorder (CUD). Number of DSM-5 criteria fulfilled and RCI were used to determine the change in SUD levels. RESULTS No association was found between adherence to/abandonment of treatment and AUD severity levels (χ2 = 7.029, p = 0.071) or CUD severity levels (χ2 = 2.044, p = 0.413). Statistical significant differences for levels of AUD (z = -3.870, p = 0.000) and CUD (z = -5.382, p = 0.000) were found between baseline assessment and follow-up. According to the number of DSM-5 criteria and RCI, the Kappa coefficient for the change in patient status (improved, worsened, or no change) was k = 0.61 for alcohol patients and k = 0.64 for cocaine patients. The "mild" category showed the greatest inconsistency between both procedures. CONCLUSIONS Levels of SUD are sensitive to the impact of treatment as measured by the difference between the baseline assessment and 3-month follow-up. However, conclusions differ according to whether the DSM-5 criteria or the RCI is applied.

Abstract
The current article highlights key issues in defining, studying, and treating addiction, a concept related to but distinct from substance use disorders. The discussion is based upon a roundtable discussion at the 2017 annual meeting of the Research Society on Alcoholism where Warren K. Bickel and John C. Crabbe were charged with answering a range of questions posed by Kenneth J. Sher. All the presenters highlighted a number of central concerns for those interested in assessing and treating addiction as well as those seeking to conduct basic preclinical research that is amenable to meaningful translation to the human condition. In addition, the discussion illustrated both the power and limitations of using any single theory to explain multiple phenomena subsumed under the rubric of addiction. Among the major issues examined were the important differences between traditional diagnostic approaches and current concepts of addiction, the difficulty of modeling key aspects of human addiction in nonhuman animals, key aspects of addiction that have, to date, received little empirical attention, and the importance of thinking of recovery as a phenomenon that possibly involves processes distinct from those undergirding the development and maintenance of addiction.

Abstract
BACKGROUND Individuals with alcohol use disorders (AUDs) who smoke cigarettes experience greater health risks than those using either substance alone. Further, disparities exist in AUDs and smoking by race/ethnicity. Although smoking has declined in the general population, it is not known whether the smoking prevalence has changed over time for individuals with AUDs. The current study used representative U.S. data to estimate the prevalence of current cigarette use from 2002 to 2016 by AUD status and severity overall and by race/ethnicity. METHODS Data were drawn from the National Survey on Drug Use and Health, an annual cross-sectional study of U.S. individuals, from 2002 to 2016 (total analytic sample n = 837,326). Cigarette smoking prevalence was calculated annually among those with and without past-year AUD and by AUD severity level (mild, moderate, severe AUD). Time trends in smoking prevalence by AUD status and severity were tested using logistic regression for the overall sample and significant interactions were subsequently stratified by race/ethnicity (non-Hispanic [NH] White, NH Black, Hispanic, NH Other). RESULTS Cigarette use was persistently over twice as common among those with AUDs compared to without AUDs (2016: 37.84% vs. 16.29%). Cigarette use was also more common among those at each level of AUD severity criteria (2016: mild AUD 34.59%; moderate AUD 35.35%; severe AUD 52.23%). Approximately half of NH Black respondents with AUDs, and three-quarters of NH Black respondents with severe AUDs, reported smoking in 2016. The prevalence of smoking decreased significantly over time among respondents with and without AUDs; however, there were differences by race. There was no decline in smoking prevalence among NH Black respondents with AUDs over time in contrast to a significant decrease for every other racial/ethnic group with and without AUDs. CONCLUSIONS Individuals with AUDs may need additional resources and interventions to quit smoking, especially NH Black individuals.

Abstract
BACKGROUND Low working memory (WM) capacity is associated with alcohol use disorders (AUDs). The importance of WM to adaptive functioning has led to a recent influx of studies attempting to improve individual WM capacity using various cognitive training methods. The present study aimed to examine the efficacy of complex WM training for improving WM capacity among individuals with AUD. METHODS Individuals were randomized to complete either adaptive WM training or active control training. We applied a methodologically rigorous and structured approach, including a battery of near and moderate transfer measures in those with AUDs and a control group. Additionally, we examined cognitive factors (at baseline) and other predictors of adherence, training task improvement, and transfer. RESULTS Results suggest improved WM in individuals with AUDs and controls, as evidenced by improved scores on several transfer measures, after adaptive WM training. However, individuals with AUDs showed poorer adherence and less improvement on the training tasks themselves. Neither IQ, WM, sex, nor condition predicted adherence. Level of training task performance, baseline WM, and IQ predicted transfer task improvement. CONCLUSIONS This is the first study to rigorously examine both the efficacy of WM training in those with AUDs, and predictors of successful training program adherence and transfer in a large sample. Among study completers, results suggest that AUD status does not predict training improvement and transfer. However, AUD status did predict lower program adherence. WM training was more effective in those with higher cognitive ability at baseline. This study provides direct translation to the development of cognitive interventions for treating AUD.

Abstract
BACKGROUND Animal models are critical for studying causal explanations of relapse. Using a Pavlovian conditioning procedure with alcohol, we examined relapse after extinction triggered by either re-exposure to alcohol (reinstatement) or a delay between extinction and test (spontaneous recovery). METHODS Male, Long-Evans rats were acclimated to 15% alcohol in the home-cage using an intermittent-access 2-bottle choice procedure. Next, they received Pavlovian conditioning sessions in which an auditory-conditioned stimulus (CS; 20 second white noise; 8 trials/session; variable time 240 seconds) was paired with 15% alcohol (0.3 ml/CS; 2.4 ml/session) that was delivered into a fluid port for oral ingestion. In subsequent extinction and test sessions, CS presentations occurred as before, but without alcohol. RESULTS In experiment 1, exposure to either alcohol or water in the fluid port following extinction reinstated CS-elicited port entries at test 24 hours later. In a follow-up study using the same procedure (experiment 2), reinstatement was more robustly stimulated by alcohol, compared to a familiar lemon-flavored liquid. In experiment 3, systemic alcohol injections (0, 0.5, or 1.0 g/kg, intraperitoneal) administered either 24 hours or 15 minutes before test did not reinstate CS-elicited alcohol-seeking. Importantly, enzymatic assays in experiment 4 revealed detectable levels of alcohol in the blood following oral alcohol intake or intraperitoneal injection, suggesting that a pharmacological effect was likely with either route of administration. Last, in experiment 5, a 23-day delay between extinction and test resulted in a robust spontaneous recovery of CS-elicited alcohol-seeking. CONCLUSIONS The reinstatement and spontaneous recovery effects revealed herein provide evidence of viable new behavioral paradigms for testing interventions against relapse.

Abstract
BACKGROUND Hepatitis C virus (HCV) infection and alcohol use disorder (AUD) both adversely affect the immune system resulting in alterations in immune cell signaling and inflammatory processes. The aim of this study was to investigate how comorbid AUD contributes to abnormalities in inflammatory mediators and psychiatric impairments in adults with HCV. METHODS Alcohol use, mood, and inflammatory factors were evaluated at 3 time points (baseline, week 4, and week 12) in Veterans with HCV, with (n = 42) and without (n = 13) comorbid AUD. Peripheral indices of immune activation, blood-brain barrier (BBB) damage (S100 calcium-binding protein B [S100B]), liver function, and viral load were measured using immunoassays and polymerase chain reaction assays. RESULTS Comorbid AUD was associated with increased symptoms of depression and anxiety, elevated levels of liver enzymes, and altered expression of inflammatory factors. Alcohol consumption was positively correlated with the severity of psychiatric symptoms. Univariate analysis identified significant group differences in interleukin (IL)-8 (p = 0.006), IL-10 (p = 0.03), and S100B (p = 0.048), with increased levels in participants with AUD, which persisted over time despite reductions in alcohol use and no significant change in HCV viral load. Statistically significant effects of study group or time were not found for the other immune factors assessed. Exploratory receiver operating characteristic curve analysis evaluated the ability of IL-8, IL-10, and S100B to differentiate between levels of alcohol consumption and generated biomarker cutoff values used to identify low risk and unhealthy alcohol use groups. CONCLUSIONS These results demonstrate that HCV and comorbid AUD are associated with greater psychiatric impairments, potentially resulting from increased inflammation, dysregulated cytokine expression, and compromised BBB function. Alcohol-induced BBB damage may increase the risk of neuropathological consequences within the context of chronic HCV infection.

Abstract
BACKGROUND Alcohol withdrawal (AW) is an important clinical and diagnostic feature of alcohol dependence. AW has been found to predict a worsened course of illness in clinical samples, but in some community studies, AW endorsement rates are strikingly high, suggesting false-positive symptom assignments. Little research has examined the validity of the DSM-5 algorithm for AW, which requires either the presence of at least 2 of 8 subcriteria (i.e., autonomic hyperactivity, tremulousness, insomnia, nausea, hallucinations, psychomotor agitation, anxiety, and grand mal seizures), or, the use of alcohol to avoid or relieve these symptoms. METHODS We used item and algorithm analyses of data from waves 1 and 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (current drinkers, n = 26,946 at wave 1) to study the validity of DSM-5 AW as operationalized by the Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-IV (AUDADIS-IV). RESULTS A substantial proportion of individuals given the AW symptom reported only modest to moderate levels of alcohol use and alcohol problems. Alternative AW algorithms were superior to DSM-5 in terms of levels of alcohol use and alcohol problem severity among those with AW, group difference effect sizes, and predictive validity at a 3-year follow-up. The superior alternative algorithms included those that excluded the nausea subcriterion; required withdrawal-related distress or impairment; increased the AW subcriteria threshold from 2 to 3 items; and required tremulousness for AW symptom assignment. CONCLUSIONS The results indicate that the DSM-5 definition of AW, as assessed by the AUDADIS-IV, has low specificity. This shortcoming can be addressed by making the algorithm for symptom assignment more stringent.

Abstract
BACKGROUND Type 2 alcoholism is characterized by low serotonin system functioning and has a high degree of heritability, with offspring of alcoholics often showing a reduced response to the intoxicating effects of ethanol (EtOH), which is thought to be marker for future alcohol use disorders (AUDs). As such, an important aim of studies investigating the origins of AUDs is to understand the relationship between serotonin system functioning and level of intoxication. A nonhuman primate model was used to evaluate observational ratings of sensitivity to EtOH and to further investigate the relationship between central serotonin activity and behavioral response to EtOH. METHODS Cerebrospinal fluid (CSF) concentrations of 5-hydroxyindoleacetic acid (5-HIAA) were obtained from 4 cohorts of alcohol-naïve, adolescent rhesus macaques (N = 82, 45 females, 37 males). One to 3 months after the CSF sample, subjects were administered a standardized intravenous EtOH bolus (males: 2.1 g/kg body weight, females: 2.0 g/kg body weight), placed into an open-top, clear plexiglass chamber suspended from the ceiling, and their latency to escape was recorded as a measure of the degree of intoxication. Thereafter, subjects were rated using a Likert scale for the degree of intoxication during a 30-minute observation period. RESULTS Our results indicate that latency to escape from the chamber was associated with intoxication ratings (p = 0.0009) following the standardized intravenous administration of EtOH. Low CSF 5-HIAA concentrations predicted short escape latency (p = 0.007) and were associated with low intoxication ratings (p = 0.02), indicating that low central nervous system (CNS) serotonin functioning is related to relative insensitivity to the intoxicating effects of alcohol. CONCLUSIONS Our study shows that, in monkeys exposed to alcohol for the first time, objective measures of intoxication are associated with subjective ratings for intoxication, and both were associated with CSF 5-HIAA concentrations. Our data confirm and extend the finding that low CNS serotonin functioning is predictive of intrinsic low sensitivity to the intoxicating effects of EtOH.

Abstract
BACKGROUND Long-lasting transcriptional changes underlie a number of adaptations that contribute to alcohol use disorders (AUD). Chromatin remodeling, including histone methylation, can confer distinct, long-lasting transcriptional changes, and histone methylases are known to play a role in the development of addiction. Conversely, little is known about the relevance of Jumonji (JmjC) domain-containing demethylases in AUDs. We systematically surveyed the alcohol-induced phenotypes of null mutations in all 13 Drosophila JmjC genes. METHODS We used a collection of JmjC mutants, the majority of which we generated by homologous recombination, and assayed them in the Booze-o-mat to determine their naïve sensitivity to sedation and their tolerance (change in sensitivity upon repeat exposure). Mutants with reproducible phenotypes had their phenotypes rescued with tagged genomic transgenes, and/or phenocopied by nervous system-specific knockdown using RNA interference (RNAi). RESULTS Four of the 13 JmjC genes (KDM3, lid, NO66, and HSPBAP1) showed reproducible ethanol (EtOH) sensitivity phenotypes. Some of the phenotypes were observed across doses, for example, the enhanced EtOH sensitivity of KDM3KO and NO66KO , but others were dose dependent, such as the reduced EtOH sensitivity of HSPBAP1KO , or the enhanced EtOH tolerance of NO66KO . These phenotypes were rescued by their respective genomic transgenes in KDM3KO and NO66KO mutants. While we were unable to rescue lidk mutants, knockdown of lid in the nervous system recapitulated the lidk phenotype, as was observed for KDM3KO and NO66KO RNAi-mediated knockdown. CONCLUSIONS Our study reveals that the Drosophila JmjC-domain histone demethylases Lid, KDM3, NO66, and HSPBAP1 are required for normal EtOH-induced sedation and tolerance. Three of 3 tested of those 4 JmjC genes are required in the nervous system for normal alcohol-induced behavioral responses, suggesting that this gene family is an intriguing avenue for future research.

Abstract
BACKGROUND An early age of drinking initiation (ADI) has been associated with increased risk for alcohol use disorders (AUDs), but the consistency of this risk across diverse samples has not been well studied. The purpose of this study was to examine whether the pathway from ADI to AUD symptoms by early adulthood is moderated by ethnicity and possessing an alcohol-metabolizing gene ALDH2*2 variant allele. METHODS We used multigroup structural equation modeling, including 5 groups split by ethnicity and ALDH2*2, to examine the consistency of the path from ADI to AUD symptoms in 604 Chinese-, Korean-, and White-American college students. We further examined the effects of ALDH2*2, ethnicity, and their interaction in Asians to better understand their unique contributions to the moderation. RESULTS The association between ADI and AUD symptoms was moderated, with ADI negatively associated with AUD symptoms among Koreans without ALDH2*2 and Whites, but not among Koreans with ALDH2*2 or Chinese regardless of ALDH2*2. Both ALDH2*2 and ethnicity within Asians contributed unique variability in the effect. CONCLUSIONS Ethnicity and ALDH2*2 altered the relationship of ADI as a risk factor for AUD symptoms. Being Chinese and possessing an ALDH2*2 allele within Koreans both buffered against the risk for AUD symptoms associated with earlier ADI, indicating that this relationship can be attenuated by protective factors.

Abstract
BACKGROUND Alcohol use disorders (AUDs) are associated with increased discounting of delayed rewards and reduced executive working memory (eWM) capacity. This association is amplified when comorbid with antisocial psychopathology (AP). Furthermore, recent studies suggest that reduced WM capacity is associated with disinhibited decisions reflected by increased impulsive decision making on the delay discounting of rewards task. While discounting of delayed rewards is well studied, the discounting of delayed losses has received significantly less experimental attention. METHODS The current study investigated (i) the rate of discounting of delayed losses in individuals with AUD only (n = 61), AUD with comorbid AP (n = 79) and healthy controls (n = 64); (ii) the relationship between eWM capacity and discounting of delayed losses; and (iii) the effect of a WM load on discounting of delayed losses. Discounting performance was assessed using a computerized discounting of delayed losses task. RESULTS Results showed that the AUD-only and AUD-AP groups had higher rates of discounting of delayed losses and lower eWM capacity compared to the control groups. Lower individual eWM capacity was associated with increased discounting of delayed losses. However, WM load did not increase discounting rates overall. CONCLUSIONS These results support the hypothesis that greater discounting of delayed losses is associated with AUD and comorbid AP problems and lower individual eWM capacity.

Abstract
BACKGROUND Alcohol use disorders (AUDs), including alcohol dependence and alcohol abuse defined according to specific DSM-IV and ICD-10 criteria, can be potentially lethal, because they are associated with several medical and psychiatric conditions. This study aimed to describe the causes of hospitalization of a large cohort of subjects with alcohol dependence (alcoholics) enrolled in Florence (Italy) over a 5-year follow-up period and to evaluate the effect of hospitalization on overall survival. METHODS One thousand one hundred and thirty alcoholics, newly diagnosed from 1997 to 2001, were linked to the Regional Mortality Registry for update of vital status as of December 31, 2006, and to the Hospital Discharge electronic archives of the Regional Health System of Tuscany to verify hospital admissions (HAs) during the 5-year postcohort enrollment follow-up. Kaplan-Meier survival and Cox regression analyses were performed to evaluate any association of HA with overall survival. RESULTS A total of 3,916 new hospitalizations occurred during the 5-year follow-up. Most alcoholics (70.6%) reported at least 1 new hospitalization, with a first hospitalization rate of 61.7 per 100 person-years in the first year of follow-up. The mean number of hospitalizations per admitted subject was 4.87 (SD 7.4), and mean length of hospital stay was 8.5 days (SD 11.3). The main causes of hospitalization were mental disorders and diseases of the digestive system, as well as accidents or violence. Among those alcoholics alive after 1 year of follow-up, a significantly increased risk of dying in the following years could be predicted by early hospitalization in the 12 months preceding (hazard ratio [HR] 1.73; 95% confidence interval [CI] 1.15 to 2.60) or following (HR 3.59; 95% CI 2.31 to 5.61) enrollment in the cohort. CONCLUSIONS Our results confirm the association of AUDs with several serious medical conditions. This fact may be responsible for a high impact on health resource utilization and high social costs. Early hospitalization significantly predicts vital status at 5 years.

Abstract
BACKGROUND Previous studies demonstrated that patients with alcohol use disorders (AUDs) show altered startle reflex responses to alcohol-related stimuli. However, there is little information about the role of these altered responses in the development of AUDs. This study examined the startle reflex response to different visual stimuli and the role of these patterns in the development of AUDs in a 4-year follow-up. METHODS Two hundred and thirty-nine (nondependent) heavy-drinking participants were selected. In the baseline period, the startle reflex responses to alcohol-related, aversive, appetitive, and neutral pictures were assessed. Startle reflex responses to these pictures were used as predictive variables. Status drinking (alcohol dependence and nondependence) assessed at 4-year follow-up was used as outcome measure. RESULTS At the 4-year follow-up assessment, 46% of participants fulfilled DSM-IV alcohol abuse or dependence criteria. Alcohol dependence status was predicted by an attenuated startle reflex response to alcohol-related and aversive pictures. CONCLUSIONS This study revealed that an attenuated modulation of startle reflex response to alcohol-related and aversive stimuli could be used as a clinical marker to predict the development of AUDs in participants with previous alcohol consumption.

Abstract
BACKGROUND Posttraumatic stress disorder (PTSD) and alcohol use disorder disproportionately impact certain populations including American Indians/Alaska Natives (AIAN). While PTSD and alcohol use disorder have been studied both separately and in tandem, less is known about the association in AIAN. The objective was to examine the association between lifetime PTSD and past year alcohol use disorder among AIAN and non-Hispanic Whites (NHW). METHODS Data come from the 2012 to 2013 U.S. National Epidemiologic Survey on Alcohol and Related Conditions-III. We used logistic regression to estimate odds of AUD among adults with and without PTSD by race. RESULTS A total of 19,705 participants, of whom 511 were AIAN and 19,194 were NHW, were included in this study. The percentage of PTSD among AIAN was 22.9% (n = 117) compared to 11.7% (n = 2,251) in NHW (p-value <0.0001). The percentage of past year alcohol use disorder among AIAN was 20.2% (n = 103) compared to 14.2% (n = 2,725) in NHW (p-value <0.0001). The percentage of comorbid past year alcohol use disorder with lifetime PTSD among AIAN was 6.5% (n = 33) compared to 2.4% (n = 457) in NHW (p-value <0.0001). Regarding the joint distribution of PTSD and AUD, AIAN men have greater than 3 times the percentage compared to NHW men (9.5% vs. 3.1%). When stratifying by race (after adjusting for age, sex, depression, and education), among AIAN, the odds of past year alcohol use disorder with (vs. without) lifetime PTSD were 1.76 (95% CI 1.07, 2.90) and among NHW, the odds were 1.59 (95% CI 1.41, 1.80). CONCLUSIONS PTSD is significantly associated with alcohol use disorder in the study populations. Despite a lack of pre-PTSD measures of alcohol use disorder, these findings show a trend indicating that AIAN exposed to PTSD are more burdened with alcohol use disorder compared to NHW in the general U.S. POPULATION

Abstract
BACKGROUND Relapse in alcohol use disorders (AUD) is related to a complex interplay among multiple biological, psychiatric, psychological, and psychosocial factors, which may change dynamically during and after treatment. At treatment entry for AUD, morphological abnormalities in anterior frontal regions and the insula have been observed in those who ultimately relapse following treatment. The goal of this study was to determine whether anterior frontal and insula measures of brain thickness, surface area, and volume predict posttreatment drinking status (i.e., relapser or abstainer) over an extended period after outpatient treatment for AUD, while concurrently considering common psychiatric, psychological, and psychosocial factors previously associated with relapse. METHODS Alcohol-dependent individuals (n = 129) were followed for 18 months after treatment to determine posttreatment drinking status (abstainers [n = 47] or relapsers [n = 82]). Brain morphometrics were derived from FreeSurfer. Receiver operating characteristic (ROC) curve analysis was used to identify the regional brain thickness, surface area, and volume (all scaled to intracranial volume), demographic, psychiatric, other substance use (e.g., cigarette smoking), and alcohol consumption variables, obtained at entry into treatment, that best predicted posttreatment drinking status. Survival analyses determined variables that were related to duration of abstinence after treatment. RESULTS ROC analyses indicated that mood disorders, education, and volumes of the right caudal anterior cingulate cortex (ACC), right rostral ACC, and total right frontal gray matter were significant predictors of posttreatment drinking status. Among relapsers, survival analyses showed smokers and individuals with a comorbid medical condition relapsed earlier after treatment. Additionally, a greater frequency of smokers relapsed within 6 months of AUD treatment. CONCLUSIONS Results reinforce that relapse in AUD is a function of multiple biological, psychiatric, psychological, and psychosocial factors. Effective treatment of depressive disorders and cigarette smoking concurrent with AUD-focused interventions may promote better treatment outcomes.

Abstract
BACKGROUND A common single nucleotide polymorphism (C385A) in the human fatty acid amide hydrolase (FAAH) gene has been associated with decreased distress responses in healthy volunteers, but its role in psychiatric disorders remains unknown. Here, we obtained genotypes and carried out a secondary analysis of subjects from a trial of comorbid posttraumatic stress disorder (PTSD) and alcohol dependence (AD). We evaluated the effects of C385A variation on behavioral and biochemical biomarkers of distress responses. METHODS Forty-nine patients with PTSD and AD were admitted for 4 weeks to an experimental medicine unit at the National Institutes of Health Clinical Center. Following detoxification, stress reactivity and peripheral endocannabinoid (eCB) levels were assessed in response to a challenge session using personalized auditory guided imagery. Over the course of the study, subjects were also evaluated for changes in PTSD symptom severity. RESULTS FAAH C385A allele carriers showed a marked increase in serum anandamide levels at baseline and throughout the stress challenge procedure compared with C allele homozygotes, while levels of eCBs primarily metabolized through other enzymatic activity, such as 2-arachidonoylglycerol, did not differ between genotype groups. FAAH C385A carriers also had decreased subjective anxiety responses to the stress challenge. Similar effects of FAAH C385A genotype were found at the level of clinical PTSD symptom severity, in particular in the arousal domain. CONCLUSIONS This is to our knowledge the first study showing that FAAH C385A variation modulates stress responses in subjects with disorders characterized by increased stress reactivity. These findings point to the eCB pathway as a promising target for future antistress therapeutics.

Abstract
BACKGROUND Cognitive behavioral therapy (CBT) is an evidence-based treatment for alcohol use disorders (AUDs), yet is rarely implemented with high fidelity in clinical practice. Computer-based delivery of CBT offers the potential to address dissemination challenges, but to date there have been no evaluations of a web-based CBT program for alcohol use within a clinical sample. METHODS This study randomized treatment-seeking individuals with a current AUD to 1 of 3 treatments at a community outpatient facility: (i) standard treatment as usual (TAU); (ii) TAU plus on-site access to a computerized CBT targeting alcohol use (TAU + CBT4CBT); or (iii) CBT4CBT plus brief weekly clinical monitoring (CBT4CBT + monitoring). Participant alcohol use was assessed weekly during an 8-week treatment period, as well as 1, 3, and 6 months after treatment. RESULTS Sixty-eight individuals (65% male; 54% African American) were randomized (TAU = 22; TAU + CBT4CBT = 22; CBT4CBT + monitoring = 24). There were significantly higher rates of treatment completion among participants assigned to 1 of the CBT4CBT conditions compared to TAU (Wald = 6.86, p < 0.01). Significant reductions in alcohol use were found across all conditions within treatment, with participants assigned to TAU + CBT4CBT demonstrating greater increases in percentage of days abstinent (PDA) compared to TAU, t(536.4) = 2.68, p < 0.01, d = 0.71, 95% CI (0.60, 3.91), for the full sample. Preliminary findings suggest the estimated costs of all self-reported AUD-related services utilized by participants were considerably lower for those assigned to CBT4CBT conditions compared to TAU, both within treatment and during follow-up. CONCLUSIONS This trial demonstrated the safety, feasibility, and preliminary efficacy of web-based CBT4CBT targeting alcohol use. CBT4CBT was superior to TAU at increasing PDA when delivered as an add-on, and it was not significantly different from TAU or TAU + CBT4CBT when delivered with clinical monitoring only.

Abstract
BACKGROUND The high occurrence of childhood trauma in individuals with alcohol dependence is well-recognized. Nevertheless, researchers have rarely studied which types of childhood trauma often co-occur and how these combinations of different types and severities of childhood trauma are related to the patients' current addiction-related problems. We aimed to identify childhood trauma profiles in patients with alcohol dependence and examined relations of these trauma profiles with the patients' current addiction-related problems. METHODS In 347 alcohol-dependent patients, 5 types of childhood trauma (sexual abuse, physical abuse, emotional abuse, emotional neglect, and physical neglect) were measured using the Childhood Trauma Questionnaire. Childhood trauma profiles were identified using cluster analysis. The patients' current severity of addiction-related problems was assessed using the European Addiction Severity Index. RESULTS We identified 6 profiles that comprised different types and severities of childhood trauma. The patients' trauma profiles predicted the severity of addiction-related problems in the domains of psychiatric symptoms, family relationships, social relationships, and drug use. CONCLUSIONS Childhood trauma profiles may provide more useful information about the patient's risk of current addiction-related problems than the common distinction between traumatized versus nontraumatized patients.

Abstract
BACKGROUND Animal and human studies indicate that GABBR1, encoding the GABAB1 receptor subunit, and SLC6A1, encoding the neuronal gamma-aminobutyric acid (GABA) transporter GAT1, play a role in addiction by modulating synaptic GABA. Therefore, variants in these genes might predict risk/resilience for alcoholism. METHODS This study included 3 populations that differed by ethnicity and alcoholism phenotype: African American (AA) men: 401 treatment-seeking inpatients with single/comorbid diagnoses of alcohol and drug dependence, 193 controls; Finnish Caucasian men: 159 incarcerated alcoholics, half with comorbid antisocial personality disorder, 181 controls; and a community sample of Plains Indian (PI) men and women: 239 alcoholics, 178 controls. Seven GABBR1 tag single nucleotide polymorphisms were genotyped in the AA and Finnish samples; rs29220 was genotyped in the PI for replication. Also, a uniquely African, functional SLC6A1 insertion promoter polymorphism (IND) was genotyped in the AAs. RESULTS We found a significant and congruent association between GABBR1 rs29220 and alcoholism in all 3 populations. The major genotype (heterozygotes in AAs, Finns) and the major allele in PIs were significantly more common in alcoholics. Moreover, SLC6A1 IND was more abundant in controls, that is, the major genotype predicted alcoholism. An analysis of combined GABBR1 rs29220 and SLC6A1 IND genotypes showed that rs29220 heterozygotes, irrespective of their IND status, had an increased risk for alcoholism, whereas carriers of the IND allele and either rs29220 homozygote were more resilient. CONCLUSIONS Our results show that with both GABBR1 and SLC6A1, the minor genotypes/alleles were protective against risk for alcoholism. Finally, GABBR1 rs29220 might predict treatment response/adverse effects for baclofen, a GABAB receptor agonist.

Abstract
BACKGROUND The current review revisits the article entitled: "Active Ingredients: How and Why Evidence-Based Alcohol Behavioral Treatment Interventions Work" published in Alcoholism: Clinical and Experimental Research. This work summarized proceedings from a 2004 Symposium of the same name that was held at the Annual Meeting of the Research Society on Alcoholism (RSA). A decade has passed, which provides occasion for an evaluation of progress. In 2014, an RSA symposium titled Active Treatment Ingredients and Client Mechanisms of Change in Behavioral Treatments for Alcohol Use Disorders: Progress 10 Years Later did just that. METHODS The current review revisits state-of-the-art research on the 3 treatments examined 10 years ago: cognitive behavioral therapy, alcohol behavior couples therapy, and 12-step facilitation. Because of its empirically validated effectiveness and robust research agenda on the study of process outcome, motivational interviewing has been selected as the fourth treatment modality to be discussed. For each of these 4 treatments, the reviewers provide a critical assessment of current theory and research with a special emphasis on key recommendations for the future. RESULTS Noteworthy progress has been made in identifying active ingredients of treatments and mechanisms of behavior change in these 4 behavioral interventions for alcohol and other drug use disorders. Not only have we established some of the mechanisms through which these evidence-based treatments work, but we have also uncovered some of the limitations in our existing frameworks and methods. CONCLUSIONS Further progress in this area will require a broader view with respect to conceptual frameworks, analytic methods, and measurement instrumentation.

Abstract
BACKGROUND Individuals in recovery from alcohol use disorders (AUDs) frequently continue to smoke cigarettes. The purpose of this study was to examine the relationship between cigarette smoking status and risk of AUD relapse in adults with remitted AUDs among adults in the United States. METHODS Data were drawn from Wave 1 (2001 to 2002) and Wave 2 (2004 to 2005) of the National Epidemiologic Survey on Alcohol and Related Conditions. Analyses included the subsample of respondents who completed both waves of data collection reported a history of alcohol abuse and/or dependence prior to Wave 1 (N = 9,134). Relationships between Wave 1 cigarette smoking status (nonsmoker, daily cigarette smoker, and nondaily cigarette smoker) and Wave 2 alcohol use, abuse, and dependence were examined using logistic regression analyses. Analyses were adjusted for Wave 1 demographics; mood, anxiety, and substance use disorders; nicotine dependence; and AUD severity. RESULTS Both daily and nondaily cigarette smoking at Wave 1 were significantly associated with a lower likelihood of alcohol use and a greater likelihood of alcohol abuse and dependence at Wave 2 compared to Wave 1 nonsmoking. These relationships remained significant after adjusting for demographics, psychiatric disorders, substance use disorders, AUD severity, and nicotine dependence. CONCLUSIONS Among adults with remitted AUDs, daily and nondaily use of cigarettes was associated with significantly decreased likelihood of alcohol use and increased likelihood of alcohol abuse and alcohol dependence 3 years later. Concurrent treatment of cigarette smoking when treating AUDs may help improve long-term alcohol outcomes and reduce the negative consequences of both substances.

Abstract
BACKGROUND While alcohol-related problems have been found to be overrepresented in clinical samples of patients, less is known about health services utilization in the general population. METHODS To explore the association of risky drinking and alcohol use disorders (AUD) with inpatient and outpatient services utilization, data are analyzed from a merged sample of 13,165 respondents in the 2005 and 2010 U.S. National Alcohol Surveys. Propensity score weighting was used to minimize potential bias associated with the heterogeneity in individual-level characteristics across respondents which might influence these relationships. RESULTS No significant differences were found between risky and nonrisky drinkers on any of the utilization variables in the last year, with 11% reporting an emergency room (ER) visit, a third reporting a primary care visit, and 6.2 to 7.6% reporting hospitalization. Those with an AUD were significantly more likely than those without to report an ER visit in the last year (18.2% vs. 11.6%; p = 0.003) as well as a greater number of such visits (p = 0.007), and to report more primary care visits (p = 0.05) and any hospitalization (11.2% vs. 6.7%; p = 0.019). CONCLUSIONS The data suggest a significant and potentially costly increase in health services utilization due to AUD. ERs and primary care settings would benefit from devoting increased resources to addressing AUD, which could result in clinical benefits of improvement in overall health status as well as economic benefits in lowering healthcare costs for both patients and society as a whole.

Abstract
BACKGROUND Few epidemiologic studies have examined a full range of adolescent psychiatric disorders in the general population. The association between psychiatric symptom clusters (PSCs) and DSM-IV alcohol use disorders (AUDs) among adolescents is not well understood. METHODS This study draws upon the public-use data from the 2000 National Household Survey on Drug Abuse, including a study sample of 19,430 respondents aged 12 to 17. Logistic regression and exploratory structural equation modeling assess the associations between PSCs and DSM-IV AUDs by gender. The PSCs are based on brief screening scales devised from the Diagnostic Interview Schedule for Children Predictive Scales. RESULTS Several PSCs were found to be significantly associated with DSM-IV AUDs, including separation anxiety, generalized anxiety, depression, oppositional defiant disorder, and conduct disorder among both genders, and panic disorder and obsessive/ compulsive disorder among females. Consistent with the literature, the analysis of PSCs yields 3 factors identical for both genders-2 internalizing factors (fear and anxiety-misery) and 1 externalizing factor. Adolescents who scored higher on the externalizing factor tended to have higher levels of the AUD factor. Female adolescents who scored higher on the internalizing misery factor and lower on the internalizing fear factor also tended to have higher levels of the AUD factor. CONCLUSIONS The associations that we found between PSCs and AUDs among adolescents in this study are consistent with those found among adults in other studies, although gender may moderate associations between internalizing PSCs and AUDs. Our findings lend support to previous findings on the developmentally stable associations between disruptive behaviors and AUDs among adolescents as well as adults in the general population.

Abstract
BACKGROUND Subjective perceptions of alcohol intoxication are associated with altered risk for alcohol abuse and dependence. Acute adaptation of these perceptions may influence such risk and may involve genes associated with pleasant perceptions or the relief of anxiety. This study assessed the effect of variation in the GABAA receptor genes GABRG1 and GABRA2 and recent drinking history on the acute adaptation of subjective responses to alcohol. METHODS One hundred and thirty-two nondependent moderate to heavy drinkers, aged 21 to 27, participated in 2 single-blind, counterbalanced sessions, approximately 1 week apart. One session was an intravenous alcohol "clamp," during which breath alcohol concentration was held steady at 60 mg/dl (60 mg%) for 3 hours, and the other an identical session using saline infusion. Subjective perceptions of Intoxication, Enjoyment, Stimulation, Relaxation, Anxiety, Tiredness, and Estimated Number of Drinks were acquired before (baseline), and during the first and final 45 minutes of the clamp. A placebo-adjusted index of the subject's acute adaptation to alcohol was calculated for each of the 7 subjective measures and used in a principal component analysis to create a single aggregate estimate for each subject's adaptive response to alcohol. Analysis of covariance tested whether GABRA2 and GABRG1 single nucleotide polymorphism (SNP) genotypes, gender, placebo session, family history of alcoholism, recent drinking history, and the genotype × recent drinking history interaction significantly predicted the adaptive response. RESULTS Recent drinking history (p = 0.01), and recent drinking history × genotype interaction (p = 0.01) were significantly associated with acute adaptation of the subjective responses to alcohol for the GABRA2 SNP rs279858. CONCLUSIONS Higher recent drinking was found to be associated with reduced acute tolerance to positive, stimulating effects of alcohol in carriers of the rs279858 risk allele. We postulate that the GABRA2 effect on alcohol dependence may, in part, be due to its effect on subjective responses to alcohol.

Abstract
OBJECTIVE To compare the prevalence of Alcohol Use Disorders (AUD) among schizophrenia patients with that of the general population in a south Indian rural community. METHODS Alcohol use pattern of 254 schizophrenia patients in the past year was compared with randomly selected healthy comparison subjects (n=350) from the same community in an administrative block of rural India using the Alcohol Use Disorders Identification Test (AUDIT). RESULTS A significantly smaller proportion of patients used alcohol in the past year (10.2%; 95% CI: 6.5%-14.0%) than controls (18.3%; 95% CI: 15.8%-24.1%; OR=2.2; 95% CI=1.4-3.5). This was true for AUD (hazardous use and harmful use; total AUDIT score >8) also: 5.5% patients (95% CI: 2.7%-8.3%) and 10.3% controls (95% CI: 7.1%-13.4%) had hazardous use (OR=2.0; 95% CI=1.0-3.7). Hazardous use was associated with domicile in villages and lesser years of education. On logistic regression, after controlling for these confounds, the odds of having AUD were 2.7 times more for controls than for patients (95% CI=1.4-5.2). CONCLUSIONS Prevalence of AUD is significantly lower in patients than in the general population in this community. Cross-cultural studies are needed to elucidate factors that underlie contrasting results across different countries.

Abstract
BACKGROUND Screening and brief intervention (SBI) is effective in reducing alcohol use, particularly among moderate risk patients. Results of SBI are inconsistent among patients with alcohol use disorders (AUDs). The Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) is used as a screening tool in many existing SBI programs. ASSIST validation studies have identified risk level cutoff scores using criteria for AUD and have not included a criterion measure for at-risk drinking (ARD), the group for whom SBI is most effective. This study examines the ability of the ASSIST to identify unhealthy alcohol use (ARD or AUD) and AUD in patients presenting to urgent care. METHODS Data were obtained from interviews with 442 adult drinkers presenting to 1 of 3 urgent care clinics. Subjects completed the ASSIST, a 90-day timeline follow-back interview to detect ARD, and a modified Diagnostic Interview Schedule to identify AUD. Validity measures compared the specificity and sensitivity of cutoff scores for the ASSIST in detecting unhealthy alcohol use and AUDs. RESULTS The optimal ASSIST score for detecting unhealthy alcohol use is 6+ for males (sensitivity and specificity 68 and 66%, respectively) and 5+ for females (62%/70%). Sensitivity, specificity, and receiver operating characteristic values were lower than those previously reported for the Alcohol Use Disorders Identification Test (AUDIT). For AUD, the optimal ASSIST cutoff scores are 10+ for males (63%/85%) and 9+ for females (63%/85%). While higher scores provided increased specificity, thereby reducing the percentage of false positives, sensitivity dropped sharply as scores increased. CONCLUSIONS Optimal ASSIST cutoff scores for unhealthy alcohol use are lower than those commonly used in many SBI programs. Use of lower ASSIST cutoff scores may increase detection of unhealthy alcohol use and increase the numbers served by SBI programs.

Abstract
OBJECTIVES Young adults have some of the highest rates of problem drinking and alcohol use disorders (AUDs) relative to any other age. However, recent evidence suggests that the DSM-IV hierarchical classification system of AUDs does not validly represent symptoms in the population; instead, it evinces a unitary, dimensional classification scheme. The DSM-5 has been altered to fit this changing, evidence-based conceptualization. Nevertheless, little is understood about the degree to which known risk factors for DSM-IV AUD diagnoses will transfer to the new DSM-5 guidelines in this group of high-risk drinkers. The current study built a coherent model of liabilities for DSM-IV AUDs in young adults and tested for transferability to DSM-5. METHODS N = 496 college students (51.10% male) were assessed on a variety of factors related to AUD risk, including demographics, substance use (past 90-days), and drinking motives. Liability models were created using all variables in Structural Equation Modeling to test direct and indirect effects on DSM diagnostic status. The best model under the DSM-IV was chosen based on fit and parsimony. This model was then applied to the DSM-5 system to test for transferability. RESULTS The best the fitting model for DSM-IV included direct influences of drug use, quantity-frequency of alcohol consumption, and social and coping drinking motives. Improved model fit was found when the DSM-5 system was the outcome. CONCLUSIONS Knowledge of risk factors for AUDs appear to transfer well to the new diagnostic system.

Abstract
BACKGROUND Brain cell death is a major pathological consequence of alcohol neurotoxicity. However, the molecular cascades in alcohol-induced brain tissue injury are unclear. METHODS Using Western blot and double immunofluorescence, we examined the expression of interferon (IFN)-induced protein kinase R (PKR), phosphorylated-PKR (p-PKR), and IFN gamma (IFNγ) in the prefrontal cortex (PFC) of postmortem brains from subjects with alcohol use disorders (AUD). RESULTS The protein levels of PKR, p-PKR, and IFNγ were significantly increased in subjects with AUD compared with control subjects without AUD, and a younger age of onset of AUD was significantly correlated with higher protein levels of p-PKR. In addition, elevated PKR- and p-PKR-IR were observed in both neurons and astrocytes in the PFC of subjects with AUD compared to subjects without AUD. CONCLUSIONS The activation of the IFNγ-PKR pathway in PFC of humans is associated with chronic excessive ethanol use with an age of onset dependent manner, and activation of this pathway may play a pivotal role in AUD-related brain tissue injury. This study provides insight into neurodegenerative key factors related to AUD and identifies potential targets for the treatment of alcohol-induced neurotoxicity.

Abstract
We review recent advances in the application of behavioral economics to alcohol use disorders (AUDs). Specifically, we review individual differences in alcohol demand (i.e., the relative reinforcing value of alcohol) and delayed reward discounting (i.e., impulsive decision making) in relation to AUDs. Additionally, we review the efficacy of reinforcement-based clinical applications. What emerges from the literature is an extensive body of cross-sectional research implicating alcohol demand and delayed reward discounting with alcohol misuse. However, more research is needed to examine these domains across the lifespan in order to understand their longitudinal trajectories. Similarly, clinical research is consistently supportive of reinforcement-based clinical interventions, but the number of randomized controlled trials to date is relatively small and there has been limited examination of the putative mechanisms of behavior change.

Abstract
AIMS This commentary critically evaluates the use of substance-related negative psychosocial and health consequences to define and diagnose alcohol and other substance use disorders. METHODS Narrative review. RESULTS The consequences of substance use cause much suffering and are major public health and economic problems. However, there are a number of conceptual and measurement problems with using consequences as diagnostic criteria for substance disorders. Data indicate that substance-related consequences introduce systematic bias and degrade the validity of diagnostic systems. CONCLUSIONS Negative psychosocial and health consequences of substance use should play a fundamentally reduced role in modern diagnostic systems for, and definitions of, addictive disorders.

BACKGROUND With few exceptions there has been a dearth of research evaluating the independent and combined effects of a promising medication and an effective behavioral intervention for alcohol problems. Few studies have incorporated both theory and empirical findings to ascertain how the combination of medication and behavioral intervention interact or work synergistically to produce better outcomes or why a particular combination of pharmacological and behavioral treatment works better than another combination or either of the interventions employed alone. METHODS The PREDICT Study is one of the few pharmacotherapy trials that has utilized a behavioral intervention to reduce/delay relapse to heavy drinking. The findings in the PREDICT Study were reviewed to gain a better understanding of how the combination of pharmacotherapy and behavioral intervention can be employed to manage the course of recovery for individuals with alcohol use disorders (AUDs). RESULTS Findings in the PREDICT Study show that behavioral interventions and pharmacotherapies have complementary functions that can be utilized to address the differential needs, capabilities, and resources associated with AUDs. However, researchers were forced to rely mainly on their own clinical experiences rather than an overarching conceptual model in determining how the approach should be employed with AUD patients, thereby limiting the conclusions that could be drawn from the study findings. CONCLUSIONS Different vulnerabilities underlying AUDs should be considered in determining what kinds of behavioral interventions should be paired with particular medications. At the same time, we need to have a better understanding of the clinical course of pharmacobehavioral treatment to deal with the array of problems/situations that arise over the course of combination therapy.

Abstract
BACKGROUND Sleep disturbances are both common and well-characterized in adults with alcohol use disorders (AUDs), but have received little study in adolescents with AUDs. Furthermore, a handful of studies suggest that sleep complaints are a risk factor for AUDs. However, no published studies have yet examined the longitudinal course of sleep complaints in adolescents with AUDs; in particular, it remains unclear how persistent AUD-associated sleep complaints are in this age group, and what types of sleep complaints are most relevant to alcohol-use symptoms. We investigated these questions in a 5-year longitudinal study of adolescents with and without AUDs at baseline. METHODS Participants were 696 adolescents (age 12 to 19) from a longitudinal study at the Pittsburgh Adolescent Alcohol Research Center. At baseline, 347 participants had a current AUD (AUD+), while 349 had no current or past AUD (AUD-). We examined sleep and alcohol involvement at baseline as well as 1-, 3-, and 5-year follow-up visits. Sleep variables included self-reported insomnia and hypersomnia, as well as variability in weekday-weekend sleep duration, all at baseline. Covariates included sex, age, current alcohol symptoms, and depression severity. RESULTS The AUD+ group reported more overall sleep disturbance at baseline, including greater insomnia and hypersomnia complaints, and greater variability in weekday-weekend sleep duration. Group differences in insomnia and hypersomnia complaints persisted to the 5- and 3-year follow-ups, respectively. In the AUD- group, greater insomnia complaints at baseline predicted an increase in alcohol symptoms at the 1-year follow-up, while greater variability in sleep duration at baseline predicted an increase in alcohol symptoms at the 3- and 5-year follow-ups. CONCLUSIONS These results complement previous findings in other samples, indicating that insomnia and other sleep problems are a chronic predicament for adolescents with AUDs. The findings also suggest that sleep disturbances may place adolescents without AUDs at an elevated risk of developing alcohol problems.

Abstract
BACKGROUND Influenced by several trials and reviews highlighting positive outcomes, topiramate is increasingly prescribed as a treatment for alcohol use disorders (AUDs). The only previously published meta-analysis of topiramate for AUDs was limited by a sample of only 3 randomized, placebo-controlled trials (RCTs). METHODS A systematic search identified 7 RCTs (including a total of 1,125 participants) that compared topiramate to placebo for the treatment for AUDs. This meta-analysis estimated the overall effects of topiramate on abstinence, heavy drinking, craving, and γ-glutamyltranspeptidase (GGT) outcomes and included several sensitivity analyses to account for the small sample of studies. RESULTS Overall, the small to moderate effects favored topiramate, although the effect on craving was not quite significantly different from 0. The largest effect was found on abstinence (g = 0.468, p < 0.01), followed by heavy drinking (g = 0.406, p < 0.01), GGT (g = 0.324, p = 0.02), and craving (g = 0.312, p = 0.07) outcomes. Sensitivity analyses did not change the magnitude or direction of the results, and tests did not indicate significant publication bias. The small sample size did not allow for examination of specific moderators of the effects of topiramate. CONCLUSIONS Topiramate can be a useful tool in the treatment of AUDs. Its efficacy, based on the current sample of studies, seems to be of somewhat greater magnitude than that of the most commonly prescribed medications for AUDs (naltrexone and acamprosate). Further research will help to identify the contexts in which topiramate is most beneficial (e.g., dose, concurrent psychotherapy, patient characteristics).

Abstract
The impending shift in DSM-5 from categorical to a hybrid categorical-dimensional diagnosis scheme has generated considerable interest in the relative merits of these respective approaches. This is particularly true for the diagnostically complex category of personality disorders (PDs). The present study assessed whether categorical or dimensional measures better predicted alcohol consumption in a sample of 102 women enrolled in a clinical trial comparing individual Cognitive Behavioral Therapy (CBT) to conjoint CBT for alcohol use disorders (AUD). Linear regression was used to evaluate whether each PD diagnosis (categorical), or the number of PD symptoms endorsed per PD (dimensional) better predicted percent days drinking over the course of six months of treatment. PD criteria (dimensional) better predicted drinking for Paranoid, Borderline, and Obsessive-Compulsive PDs, while diagnosis (categorical) was a better predictor only for Passive-Aggressive PD. Both schemes predicted drinking outcomes for Avoidant, Dependent, and Depressive PDs, and neither was predictive for Narcissistic PD. These findings suggest that the addition of a dimensional approach for PDs potentially enhances the prediction of alcohol use outcomes.

Abstract
BACKGROUND Alcohol use disorders (AUD) have long been considered to be some of the most disabling mental disorders; however, empirical data on the burden of disease associated with AUD have been sparse. The objective of this article is to quantify the burden of disease (in disability-adjusted life years [DALYs] lost), deaths, years of life lost due to premature mortality (YLL), and years of life lost due to disability (YLD) associated with AUD for the United States in 2005. METHODS Statistical modeling was based on epidemiological indicators derived from the National Epidemiologic Survey on Alcohol and Related Conditions. Formal consistency analyses were applied. Risk relations were taken from recent meta-analyses and the disability weights from the burden of disease study of the National Institutes of Health. Monte Carlo simulations were used to derive confidence intervals. All analyses were performed by sex and age. Sensitivity analyses were undertaken on key indicators. RESULTS In the United States in 2005, 65,000 deaths, 1,152,000 YLL, 2,443,000 YLD, and 3,595,000 DALYs were associated with AUD. For individuals 18 years of age and older, AUD were associated with 3% of all deaths (5% for men and 1% for women), and 5% of all YLL (7% for men and 2% for women). The majority of the burden of disease associated with AUD stemmed from YLD, which accounted for 68% of DALYs associated with AUD (66% for men and 74% for women). The youngest age group had the largest proportion of DALYs associated with AUD stemming from YLD. CONCLUSIONS Using data from a large representative survey (checked for consistency) and by combining these data with the best available evidence, we found that AUD were associated with a larger burden of disease than previously estimated. To reduce this disease burden, implementation of prevention interventions and expansion of treatment are necessary.

Abstract
BACKGROUND Alcohol dehydrogenase 1B and 1C (ADH1B and ADH1C) variants have been robustly associated with alcohol phenotypes in East Asian populations, but less so in non-Asian populations where prevalence of the most protective ADH1B allele is low (generally <5%). Further, the joint effects of ADH1B and ADH1C on alcohol phenotypes have been unclear. Therefore, we tested the independent and joint effects of ADH1B and ADH1C on alcohol phenotypes in an Israeli sample, with higher prevalence of the most protective ADH1B allele than other non-Asian populations. METHODS A structured interview assessed lifetime drinking and alcohol use disorders (AUDs) in adult Israeli household residents. Four single nucleotide polymorphisms (SNPs) were genotyped: ADH1B (rs1229984, rs1229982, and rs1159918) and ADH1C (rs698). Regression analysis examined the association between alcohol phenotypes and each SNP (absence vs. presence of the protective allele) as well as rs698/rs1229984 diplotypes (also indicating absence or presence of protective alleles) in lifetime drinkers (n = 1,129). RESULTS Lack of the ADH1B rs1229984 protective allele was significantly associated with consumption- and AUD-related phenotypes (OR = 1.77 for AUD; OR = 1.83 for risk drinking), while lack of the ADH1C rs698 protective allele was significantly associated with AUD-related phenotypes (OR = 2.32 for AUD). Diplotype analysis indicated that jointly ADH1B and ADH1C significantly influenced AUD-related phenotypes. For example, among those without protective alleles for ADH1B or ADH1C, OR for AUD was 1.87 as compared to those without the protective allele for ADH1B only and was 3.16 as compared to those with protective alleles for both ADH1B and ADH1C. CONCLUSIONS This study adds support for the relationship of ADH1B and ADH1C and alcohol phenotypes in non-Asians. Further, these findings help clarify the mixed results from previous studies by showing that ADH1B and ADH1C jointly effect AUDs, but not consumption. Studies of the association between alcohol phenotypes and either ADH1B or ADH1C alone may employ an oversimplified model, masking relevant information.

Abstract
BACKGROUND Increasing age and chronic cigarette smoking are independently associated with adverse effects on multiple aspects of neurocognition in those seeking treatment for alcohol use disorders. However, the potential interactive effects of age and cigarette smoking on neurocognition in early abstinent alcohol-dependent individuals (ALC) have not investigated. METHODS Cross-sectional performances of never-smoking healthy comparison participants (nvsCOM; n = 39) and 1-month-abstinent, treatment-seeking, never-smoking (nvsALC; n = 30), former-smoking (fsALC; n = 21), and actively smoking (asALC; n = 68) ALC were compared on a comprehensive neurocognitive battery. Domains of functioning evaluated were cognitive efficiency, executive functions, fine motor skills, general intelligence, learning and memory, processing speed, visuospatial functions and working memory. Participants were between 26 and 71 years of age at the time of assessment. RESULTS asALC showed steeper age-related effects than nvsCOM on the domains of visuospatial learning, auditory-verbal memory, cognitive efficiency, executive functions, processing speed, and fine motor skills. In pairwise comparisons, fsALC and asALC performed more poorly than both nvsCOM and nvsALC on multiple domains; nvsCOM and nvsALC showed no significant differences. Domain scores for the ALC groups generally fell in the low-to-high-average range of functioning. A clinically significant level of impairment was apparent in only 25% of ALC participants on visuospatial learning, visuospatial memory, and fine motor skills domains. Measures of alcohol use or consumption were not significantly related to neurocognition in the ALC cohorts. CONCLUSIONS The age-related findings suggest that the combination of active chronic smoking and alcohol dependence in this 1-month-abstinent ALC cohort was associated with greater than normal age-related effects in multiple domains. In general, a low level of clinically significant impairment was observed in the alcohol-dependent participants. The findings from this study, in conjunction with previous research, strongly support smoking cessation interventions for those seeking treatment for alcohol and substance use disorders.

Abstract
BACKGROUND Common variants in the CHRNA5-A3-B4 gene cluster have been shown to be associated with nicotine dependence and alcohol use disorders (AUDs) and related traits, including the level of response (LR) to alcohol. Recently, rare variants (MAF < 0.05) in CHRNB4 have been reported to be associated with a decreased risk of developing nicotine dependence. However, the role of rare variants in the CHRNA5-A3-B4 gene cluster to the LR to alcohol has not yet been established. METHODS To determine whether rare variants in the CHRNA5-A3-B4 gene cluster contribute to the LR to alcohol, the coding regions of these 3 genes were sequenced in 538 subjects from the San Diego Sibling Pair study. RESULTS The analyses identified 16 rare missense variants, 9 of which were predicted to be damaging using in silico analysis tools. Carriers of these variants were compared to noncarriers using a family-based design for each gene and for the gene cluster as a whole. In these analyses, a CHRNA5 carrier status was significantly associated with the phenotype related to the feeling of intoxication experienced during the alcohol challenge (p = 0.039). CONCLUSIONS These results indicate that rare genetic variation in the CHRNA5-A3-B4 gene cluster contributes modestly to the LR to alcohol in the San Diego Sibling Pair study and may protect against AUDs. However, replication studies are needed to confirm our findings.
