Abstract
Recent studies have demonstrated the involvement of epigenetic mechanisms in psychiatric disorders, including alcoholism. Here, we investigated the effects of histone deacetylase (HDAC) inhibitor, trichostatin A (TSA) on amygdaloid HDAC-induced histone deacetylation and neuropeptide Y (NPY) expression and on anxiety-like and alcohol-drinking behaviours in alcohol-preferring (P) and -non-preferring (NP) rats. It was found that P rats displayed higher anxiety-like and alcohol-drinking behaviours, higher amygdaloid nuclear, but not cytosolic, HDAC activity, which was associated with increased HDAC2 protein levels and deficits in histone acetylation and NPY expression in the central (CeA) and medial nucleus of amygdala (MeA), as compared to NP rats. TSA treatment attenuated the anxiety-like and alcohol-drinking behaviours, with concomitant reductions in amygdaloid nuclear, but not cytosolic HDAC activity, and HDAC2, but not HDAC4, protein levels in the CeA and MeA of P rats, without effect in NP rats. TSA treatment also increased global histone acetylation (H3-K9 and H4-K8) and NPY expression in the CeA and MeA of P, but not in NP rats. Histone H3 acetylation within the NPY promoter was also innately lower in the amygdala of P rats compared with NP rats; which was normalized by TSA treatment. Voluntary ethanol intake in P, but not NP rats, produced anxiolytic effects and decreased the HDAC2 levels and increased histone acetylation in the CeA and MeA. These results suggest that higher HDAC2 expression-related deficits in histone acetylation may be involved in lower NPY expression in the amygdala of P rats, and operative in controlling anxiety-like and alcohol-drinking behaviours.

Abstract
Background Tobacco- and alcohol use are associated with psychological problems. Individuals with high dental fear also more often report other psychological problems than do those with lower level of dental fear. We evaluated the association between dental fear and tobacco- and alcohol use while controlling for age, gender, general mood and feelings in social situations. Methods The data (n = 8514) were collected from all universities in Finland with an electronic inquiry sent to all first-year university students. Dental fear was measured with the question: “How afraid are you of visiting a dentist?” with reply alternatives “Not at all”, “Somewhat” and “Very”. Regularity of tobacco use was determined with the question: “Do you smoke or use snuff?”, with reply alternatives “Not at all”, “Occasionally” and “Daily”. The Alcohol Use Disorders Identification Test (AUDIT) was used for determination of alcohol use; an AUDIT sum score of 8 or more indicated hazardous, harmful or dependent alcohol use. The statistical tests used were Chi-square tests and Multiple logistic regression analyses. Results When controlled for age, gender, alcohol use, general mood and feelings in social situations, those who used tobacco regularly were more likely to have high dental fear than were those who used tobacco occasionally or not at all. When controlled for age, gender, general mood and feelings in social situations, those with hazardous, harmful or dependent alcohol use were more likely to have high dental fear than were those with low-risk of alcohol use, the association between alcohol use and dental fear was not strong. When tobacco use was added into this model, alcohol use was no longer statistically significantly associated with dental fear. Conclusions The findings of this study support the suggestion that some people may have common vulnerability factors linked to tobacco use, alcohol use, and dental fear.

Abstract
BACKGROUND While chronobiological studies have reported seasonal variation in panic attacks (PA) episodes, information on the timing of PA by week-days may enable better understanding of the triggers of PA episodes and thereby provide pointers for suitable interventional approaches to minimize PA attacks. This study investigated weekly variation in potential PA admissions including associations with holidays using a population-based longitudinal, administrative claims-based dataset in an Asian population. METHODS This study used ambulatory care data from the "Longitudinal Health Insurance Database 2000. We identified 993 patients with panic disorder (PD), and they had 4228 emergency room (ER) admissions for potential PA in a 3-year period between 1 January 2009 and 31 December 2011. One-way analysis of variance (ANOVA) was used to examine associations between the potential PA admissions and holidays/weekend days/work-days of the week. RESULTS The daily mean number of potential PA admissions was 3.96 (standard deviation 2.05). One-way ANOVA showed significant differences in potential PA admissions by holiday and day of the week (p<0.001). Daily frequencies showed a trough on Wednesday-Thursday, followed by a sharp increase on Saturday and a peak on Sunday. Potential PA admissions were higher than the daily mean for the sample patients by 29.4% and 22.1%, respectively on Sundays and holidays. Furthermore, the weekly variations were similar for females and males, although females always had higher potential PA admissions on both weekdays and holidays than the males. CONCLUSIONS We found that potential PA admissions among persons with PD varied systematically by day of the week, with a significant peak on weekends and holidays.

Abstract
OBJECTIVE Addiction is often considered a dissociative behavior that is related to alexithymia and developmental trauma. The study aims were to explore the relationships between early trauma, alexithymia, and dissociation. METHODS A total of 117 (males=60; females=57) alcohol-addicted individuals and 117 healthy individuals (males=60; females=57) were administered a series of self-report questionnaires that assess traumatic experiences, alexithymia, and pathological dissociation. RESULTS Correlation analyses indicated significant correlations between alexithymia, dissociation, and trauma and a significant difference between the target and control groups, with higher alexithymia and dissociation scores in the target group. CONCLUSION These findings suggest that trauma, alexithymia, and dissociation are predictors of alcohol addiction.

Abstract
BACKGROUND Anxiety has been linked to initiation, maintenance and relapse of alcohol dependence. Neurobiological models of anxiety have proposed important roles for amygdala-insula and amygdala-medial prefrontal cortex interactions in the generation and regulation of anxiety states, respectively. OBJECTIVES This study tested the hypotheses that abstinent alcohol-dependent patients would show a disruption of synchrony in these circuits as measured by resting state functional MRI. METHODS The study examined recently abstinent (n = 13), longer-term abstinent (n = 16) alcohol-dependent patients and healthy controls (n = 22). Resting-state synchrony (RSS) was examined in specific circuits, where degree of synchrony has been found to correlate with state anxiety levels in previous studies. RESULTS Alcohol-dependent patients showed significantly elevated scores on anxiety and depression inventories compared with controls. No significant group differences in synchrony were observed between right amygdala and right ventromedial prefrontal cortex (vmPFC), between left amygdala and left vmPFC, or, after correction for multiple comparisons, right amygdala and dorsomedial prefrontal cortex (dmPFC). However, significantly decreased positive synchrony was found between left basolateral amygdala and left anterior insula, in patients relative to controls. CONCLUSION Both early and longer-term abstinent alcohol-dependent patients showed increased anxiety levels relative to controls and altered resting state synchrony in circuits previously linked to state anxiety. Notably, the significant group differences in synchrony were in the opposite direction to our predictions based on the literature. These results may point to a lack of generalizability of models derived from young healthy homogeneous samples.

Abstract
Ethanol induces appetitive, aversive, and anxiolytic effects that are involved in the development of ethanol use and dependence. Because early ethanol exposure produces later increased responsiveness to ethanol, considerable effort has been devoted to analysis of ethanol's appetitive and aversive properties during early ontogeny. Yet, there is a relative scarcity of research related to the anxiolytic effects of ethanol during early infancy, perhaps explained by a lack of age-appropriate tests. The main aim of this study was to validate a model for the assessment of ethanol's anxiolytic effects in the infant rat (postnatal days 13-16). The potentially anxiolytic effects of ethanol tested included: i) amelioration of conditioned place aversion, ii) ethanol intake in the presence of an aversive conditioned stimulus, iii) the inhibitory behavioral effect in an anxiogenic environment, and iv) innate aversion to a brightly illuminated area in a modified light/dark paradigm. Ethanol doses employed across experiments were 0.0, 0.5, and 2.0 g/kg. Results indicated that a low ethanol dose (0.5 g/kg) was effective in attenuating expression of a conditioned aversion. Ethanol intake, however, was unaffected by simultaneous exposure to an aversive stimulus. An anxiogenic environment diminished ethanol-induced locomotor stimulation. Finally, animals given 0.5 g/kg ethanol and evaluated in a light/dark box showed increased time spent in the illuminated area and increased latency to escape from the brightly lit compartment than rats treated with a higher dose of ethanol or vehicle. These new results suggest that ethanol doses as low as 0.5 g/kg are effective in ameliorating an aversive and/or anxiogenic state in preweanling rats. These behavioral preparations can be used to assess ethanol's anxiolytic properties during early development.

Abstract
BACKGROUND Drinking motives are thought to be important mediators of the relationship between social anxiety and alcohol use. This project evaluates whether specific drinking motives accurately reflect alcohol dependence. If so, brief questions about drinking motives could serve as valuable alcohol screening tools with socially anxious patients. METHODS This investigation was a secondary analysis of an existing data set of 83 subjects with social anxiety disorder and at-risk alcohol use. The relationship between Drinking Motives Questionnaire (DMQ-R-5) subscales and alcohol dependence was evaluated. RESULTS Coping-Depression was the only subscale that contributed to the unique prediction of a diagnosis of alcohol dependence. Additionally, two items (i.e. "to cheer up when you're in a bad mood" and "to forget painful memories") predicted a diagnosis of alcohol dependence above and beyond their association with each other. CONCLUSIONS Among patients with social anxiety, two specific questions on the DMQ-R-5 could provide a useful screen for health professionals to predict alcohol dependence. It may be fruitful to specifically target the motives of "to cheer up when you're in a bad mood" and "to forget painful memories" when providing advice during brief interventions.

Abstract
RATIONALE Individual differences in brain structure and function are suggested to exist prior to the onset of alcohol abuse. Cross-sectional studies have demonstrated abnormalities in brain regions underlying affective processes that may form a pathway to the emergence of later alcohol abuse and dependence in vulnerable individuals. However, no prospective studies have examined whether these abnormalities predict later problems with alcohol. OBJECTIVE This study aims to examine whether individual differences in affect and brain volume prospectively predict alcohol-related problems in adolescence. METHOD Adolescent drinkers (n = 98) were recruited from an ongoing prospective, longitudinal study examining adolescent emotional development. At age 12, participants underwent structural magnetic resonance imaging to obtain volumetric data on the amygdala, hippocampus, orbitofrontal cortex, and anterior cingulate cortex (ACC), and completed a self-report measure of affective temperament. At age 16, participants completed a questionnaire measuring alcohol use, with 39 % reporting alcohol-related problems in the past year. RESULTS Pre-existing differences in the left ACC predicted problem drinking. Alcohol-related problems were associated with higher levels of temperamental negative affectivity; however, these were not correlated with anterior cingulate volumes. CONCLUSIONS These findings indicate that individual differences in the structural morphology of the anterior cingulate, a region implicated in affective processes, self-control, and drug addiction, predict later alcohol-related problems. Although this finding remained significant after controlling for other substance use and psychopathology, future research is required to test its specificity for alcohol use disorders.

Abstract
The aim of the present study was to investigate if a novelty-seeking phenotype mediates the long-lasting consequences of intermittent EtOH intoxication during adolescence. The hole board test was employed to classify adolescent mice as High- or Low-Novelty Seekers. Subsequently, animals were administered ethanol (1.25 or 2.5 g/kg) on two consecutive days at 48-h intervals over a 14-day period. Anxiety levels--measured using the elevated plus maze- spontaneous motor activity and social interaction test were studied 3 weeks later. A different set of mice underwent the same procedure, but received only the 2.5 g/kg dose of ethanol. Three weeks later, in order to induce CPP, the same animals were administered 1 or 6 mg/kg of cocaine or 1 or 2.5 mg/kg MDMA. The results revealed a decrease in aggressive behaviors and an anxiolytic profile in HNS mice and longer latency to explore the novel object by LNS mice. Ethanol exposure enhanced the reinforcing effects of cocaine and MDMA in both groups when CPP was induced with a sub-threshold dose of the drugs. The extinguished cocaine-induced CPP (1 and 6 mg/kg) was reinstated after a priming dose in HNS animals only. Our results confirm that intermittent EtOH administration during adolescence induces long-lasting effects that are manifested in adult life, and that there is an association between these effects and the novelty-seeking phenotype.

Abstract
INTRODUCTION Alcohol dependence and anxiety disorders often co-occur. Yet, the effect of co-morbid anxiety disorders on the alcohol relapse-risk after treatment is under debate. This study investigated the effect of co-morbid anxiety disorders on relapse rates in alcohol dependence. We hypothesized that co-morbid anxiety disorders would be particularly predictive for early relapse, but not late relapse. SUBJECTS AND METHODS In a prospective design, male alcohol dependent patients (n=189) were recruited from an inpatient detoxification clinic. Psychiatric diagnoses and personality traits were assessed using the Mini International Neuropsychiatric Interview for psychiatric disorders and the Temperament and Character Inventory. The addiction severity index was used to assess addiction severity and follow-up. RESULTS One year after detoxification, 81 patients (53%) relapsed and nine patients (7%) were deceased, due to alcohol related causes. Co-morbid anxiety disorder, marital status, addiction severity, in particular legal problems, and harm avoidance predicted relapse. Anxiety disorders specifically predicted early relapse. CONCLUSION Alcohol dependence is a severe mental disorder, with high relapse rates and high mortality. Alcohol dependent patients with co-morbid anxiety disorders are particularly prone to relapse during the first three months of treatment. These patients may therefore require additional medical and psychological attention.

Abstract
Research has demonstrated high rates of co-occurrence among anxiety and substance use disorders. However, few studies have specifically examined the relationship between substance use and social anxiety among individuals who are in substance abuse recovery. The present study examined social anxiety as a predictor of substance use among a sample randomized to a sober-living home versus usual aftercare. Given the social nature of many substance abuse treatment and aftercare programs, it was also hypothesized that high levels of social anxiety would reduce the length of stay in the sober-living home and negatively influence participation in self-help groups. Results suggested that social anxiety was a significant predictor of relapse at one time point, and that social anxiety decreased the likelihood for remaining in a sober-living house for six months or more. No significant relationship between social anxiety and participation in self-help groups were found. Implications for further research and substance abuse treatment are discussed.

Abstract
Beginning in 1979 with the first report that central administration of oxytocin stimulates maternal behavior in virgin rats, decades of animal research and more recent human studies have demonstrated that oxytocin has many pro-social effects. These many findings suggest that oxytocin may be an effective treatment for social deficits that are hallmark features of disorders such as autism and schizophrenia. Effects in preclinical animal models also imply that oxytocin may be an efficacious pharmacotherapy in a wide range of psychiatric disorders including psychoses and addictions. To date, 3 small clinical trials found that daily intranasal oxytocin treatment for 2-8 weeks significantly reduced psychotic symptoms in schizophrenia. Two of these trials also found improvement in social cognition or neurocognition, areas in which patients have significant deficiencies that do not respond to conventional antipsychotic treatment and contribute to disability. In another small trial, intranasal oxytocin potently blocked alcohol withdrawal. After reviewing the rationale for these trials, they are described in more detail. Questions are then asked followed by discussions of the large gaps in our knowledge about brain oxytocin systems in humans. The hope is to highlight important directions for future investigations of the role of oxytocin in the pathophysiology of psychotic disorders and addictions and to extend clinical research in these areas. Heretofore unrecognized roles for which oxytocin may have been selected during the evolution of placental mammalian maternal-infant and other social attachments are considered as possible origins of oxytocin antipsychotic and antiaddiction effects.This article is part of a Special Issue entitled Oxytocin and Social Behav.

Abstract
Development of anxiety-like behaviours during ethanol withdrawal has been correlated with increased histone deacetylase (HDAC) activity and decreased brain-derived neurotrophic factor (BDNF) and activity-regulated cytoskeleton-associated protein (Arc) gene expression in the amygdala. Furthermore, HDAC-mediated histone modifications play a role in synaptic plasticity. In this study we used the HDAC inhibitor trichostatin A (TSA) to determine whether HDAC inhibition could prevent ethanol withdrawal-induced deficits in dendritic spine density (DSD), BDNF or Arc expression in the amygdala of rats. It was found that decreased BDNF and Arc expression in the central (CeA) and medial nucleus of amygdala (MeA), observed during withdrawal after chronic ethanol exposure, were normalized following acute TSA treatment. TSA treatment was also able to attenuate anxiety-like behaviours during ethanol withdrawal and correct the observed decrease in DSD in the CeA and MeA of ethanol-withdrawn rats. Taken together, these findings demonstrate that correcting the deficits in histone acetylation through TSA treatment also amends downstream synaptic plasticity-related deficits such as BDNF and Arc expression, and DSD in the CeA and MeA as well as attenuates anxiety-like behaviours in rats during withdrawal after chronic ethanol exposure.

Abstract
BACKGROUND Soldiers face a great number of traumatic combat exposures while deployed, which research has shown to contribute to the development of alcohol misuse. In addition to this known risk factor, we hypothesize that adverse childhood experiences (ACEs) also contribute to the likelihood that soldiers will engage in these behaviors, even after adjusting for deployment-related factors (mental health problems and combat exposure). METHODS Soldiers were surveyed anonymously approximately 3 months upon return from Operation Enduring Freedom (OEF) or Operation Iraqi Freedom (OIF) from 2003 to 2006. Six brigade combat teams were included in the analyses (n=7849). Participants were asked about ACEs, mental health symptoms, alcohol misuse, risky behaviors related to alcohol misuse, and combat exposure. RESULTS Of the 7849 soldiers in the sample, 31.5% screened positive for alcohol misuse and of those almost half also screened positive for risky behaviors related to alcohol misuse (43.3%). Having an alcoholic in the household and experiencing sexual abuse were significantly associated with screening positive for alcohol misuse and alcohol misuse with risky behaviors. Experiencing sexual abuse was a strongly associated ACE item, with an almost 2-fold increase in risk of both outcomes even after adjusting for mental health problems and combat exposure. CONCLUSIONS Findings suggest that ACEs are a substantial risk factor for alcohol misuse with and without risky behaviors among soldiers returning from deployments and should be considered when directing prevention efforts.

Abstract
BACKGROUND AND AIMS Studies of alcohol habits in general psychiatric populations are scarce. The objective was to investigate alcohol and drug use, smoking, and gambling in a clinical sample of psychiatric outpatients. A further aim was to study age and gender differences in the rates of these habits. METHODS Data were collected among psychiatric outpatients with mainly mood (47%) and anxiety (35%) disorders. A questionnaire package was distributed, including AUDIT (Alcohol Use Disorders Identification Test), DUDIT (Drug Use Disorders Identification Test), tobacco items, and gambling items. Two major drinking categories were formed: "Nonhazardous alcohol use" (NH) and "Alcohol use above hazardous levels" (AH). RESULTS In total, 2160 patients (65% females) responded to the questionnaire package. The AH rate was high among psychiatric outpatients (28.4%), particularly among young females (46.6%). Young female patients also reported a high prevalence of problematic drug use (13.8%). Problematic drug use, daily smoking, and problematic gambling were frequent. The unhealthy habits were linked to AH. CONCLUSIONS Alcohol and drug use, smoking, and gambling are all highly prevalent among psychiatric outpatients. Young females are in particular need of attention. Interventions should be tailored for co-occurring psychiatric disorders and applied within routine psychiatric care.

Abstract
BACKGROUND In Sweden mental ill-health has increased among the young, especially among young women. Our aim was to investigate the association between experience of physical violence during the past year and self rated psychological health among young men and women. METHODS The study population consisted of men (n = 2,624) and women (n = 3,569) aged 18-34 years who participated in the 2008 public health survey study in Skåne. The survey was a cross-sectional stratified random sample postal questionnaire study with a 54.1% participation rate. Associations were investigated by logistic regression models. RESULTS The prevalence of poor psychological health was 18.9% among men and 27.7% among women. One in ten men and one in twenty women had experienced physical violence during the past year. Most men were violated in public places, while women were most often violated at home. Women who had experienced violence during the past year showed more than doubled odds of poor psychological health, odds ratio (OR): 2.66 (95% confidence interval (CI): 2.00, 3.53). Such an association could not be seen in men OR: 1.12 (95% CI: 0.85, 1.47). Adjustment for covariates (i.e. age, country of birth, socioeconomic status, economic stress, alcohol risk consumption, emotional support, instrumental support and generalized trust in other people) did not change the association found among women. CONCLUSION Violated women, but not men, showed nearly doubled odds of poor psychological health after multiple adjustments. There was also a gender difference regarding location of violence. Awareness of gender differences regarding context and mental impact of violence may assist public health workers in reducing the consequences of violence and to design preventive strategies.

Abstract
Alcoholism is a complex psychiatric disorder that has a multifactorial etiology. Epigenetic mechanisms are uniquely capable of accounting for the multifactorial nature of the disease in that they are highly stable and are affected by environmental factors, including alcohol itself. Chromatin remodeling causes changes in gene expression in specific brain regions contributing to the endophenotypes of alcoholism such as tolerance and dependence. The epigenetic mechanisms that regulate changes in gene expression observed in addictive behaviors respond not only to alcohol exposure but also to comorbid psychopathology such as the presence of anxiety and stress. This review summarizes recent developments in epigenetic research that may play a role in alcoholism. We propose that pharmacologically manipulating epigenetic targets, as demonstrated in various preclinical models, hold great therapeutic potential in the treatment and prevention of alcoholism.

Abstract
The pathophysiology of cocaine addiction is linked to changes within neural systems and brain regions that are critical mediators of stress system sensitivity and behavioral processes associated with the regulation of adaptive goal-directed behavior. This is characterized by the upregulation of core adrenergic and corticotropin-releasing factor mechanisms that subserve negative affect and anxiety and impinge upon intracellular pathways in the prefrontal cortex underlying cognitive regulation of stress and negative emotional state. Not only are these mechanisms essential to the severity of cocaine withdrawal symptoms, and hence the trajectory of clinical outcome, but also they may be particularly pertinent to the demography of cocaine dependence. The ability of guanfacine to target overlapping stress, reward, and anxiety pathophysiology suggests that it may be a useful agent for attenuating the stress- and cue-induced craving state not only in women but also in men. This is supported by recent research findings from our own laboratory. Additionally, the ability of guanfacine to improve regulatory mechanisms that are key to exerting cognitive and emotional control over drug-seeking behavior also suggests that guanfacine may be an effective medication for reducing craving and relapse vulnerability in many drugs of abuse. As cocaine-dependent individuals are typically polydrug abusers and women may be at a greater disadvantage for compulsive drug use than men, it is plausible that medications that target catecholaminergic frontostriatal inhibitory circuits and simultaneously reduce stress system arousal may provide added benefits for attenuating cocaine dependence.

Abstract
BACKGROUND Military studies investigating the prevalence of substance use (SU) and substance use disorders (SUD) and the relation between SU and mental disorders often lack a comprehensive assessment of SU, SUD and mental disorders and comparable groups of deployed and non-deployed personnel. There is also limited data regarding SU and SUD in the German military to date. METHODS Cross-sectional examination of n=1483 soldiers recently deployed in Afghanistan and 889 never deployed soldiers using a fully-standardized diagnostic interview (MI-CIDI) including a comprehensive substance section. RESULTS Across both groups, 12-months prevalence of DSM-IV alcohol use disorders was 3.1%, 36.9% reported binge drinking, 13.9% heavy drinking, 1.3% illegal drug use. 55.1% were regular smokers, 10.9% nicotine dependent. Although recently deployed soldiers revealed slightly higher rates in some measures, there were no significant differences to the never deployed regarding SU und SUD except that recently deployed soldiers smoked more cigarettes per day. The association of SU with mental mental disorders was substantially different though, revealing significant associations between SU and mental disorders only among recently deployed soldiers. CONCLUSIONS We do not find remarkable differences in the prevalence of SU and SUD between recently deployed and never deployed soldiers. Especially binge drinking and regular smoking were prevalent across both samples indicating needs for improved interventions. The finding that SU and mental disorders are only associated in recently deployed soldiers might have implications for improved screening and prevention and suggests that deployment might promote different pathways and mechanisms involved in the evolution of SU and mental disorders.

Abstract
BACKGROUND Alcohol consumption is associated with several complications of both physical and mental health. Light or moderate alcohol consumption may have beneficial effects on physical or mental health but this effect is still controversial and research in the mental health field is relatively scarce. Our aim was to investigate the association between varying levels of alcohol consumption and the common mental disorders of depression and anxiety in a large international primary care sample. METHODS The sample consisted of 5438 primary care attenders from 14 countries who participated in the WHO Collaborative Study of Psychological Problems in General Health Care. Alcohol use was assessed using Alcohol Use Disorders Identification Test (AUDIT) and the mental disorders were assessed with the Composite International Diagnostic Interview (CIDI). RESULTS Light to moderate alcohol consumption was associated with a lower prevalence of depression and generalized anxiety disorder compared to abstinence while excessive alcohol consumption was associated with a higher prevalence of depression. This non-linear association was not substantially affected after adjustment for a range of possible confounding variables, including the presence of chronic disease and the current physical status of participants and was evident in different drinking cultures. CONCLUSION The study confirms that excessive drinking is associated with an increased prevalence of depression, but also raises the possibility that light/moderate drinking may be associated with a reduced prevalence of both depression and anxiety. Any causal interpretation of this association is difficult in the context of this cross-sectional study and further longitudinal studies are needed.

Abstract
AIMS We examined two questions about the relationship between conduct disorder (CD), depression and anxiety symptoms and substance use onset: (i) what is the relative influence of recent and more chronic psychiatric symptoms on alcohol and marijuana use initiation and (ii) are there sensitive developmental periods when psychiatric symptoms have a stronger influence on substance use initiation? DESIGN Secondary analysis of longitudinal data from the Pittsburgh Youth Study, a cohort study of boys followed annually from 7 to 19 years of age. SETTING Recruitment occurred in public schools in Pittsburgh, Pennsylvania, USA. PARTICIPANTS A total of 503 boys. MEASUREMENTS The primary outcomes were age of alcohol and marijuana use onset. Discrete-time hazard models were used to determine whether (i) recent (prior year); and (ii) cumulative (from age 7 until 2 years prior to substance use onset) psychiatric symptoms were associated with substance use onset. FINDINGS Recent anxiety symptoms [hazard ratio (HR) = 1.10, 95% confidence interval (CI) = 1.03-1.17], recent (HR = 1.59, 95% CI = 1.35-1.87), cumulative (HR = 1.45, 95% CI = 1.03-2.03) CD symptoms, and cumulative depression symptoms (HR = 1.04, 95% CI = 1.01-1.08) were associated with earlier alcohol use onset. Recent (HR = 1.39, 95% CI = 1.22-1.58) and cumulative CD symptoms (HR = 1.38, 95% CI = 1.02-1.85) were associated with marijuana use onset. Recent anxiety symptoms were only associated with alcohol use onset among black participants. CONCLUSIONS Timing matters in the relationship between psychiatric symptoms and substance use onset in childhood and adolescence, and the psychiatric predictors of onset are substance-specific. There is no single sensitive developmental period for the influence of psychiatric symptoms on alcohol and marijuana use initiation.

Abstract
Little is known about the predictors of outcome in anxiety disorders in naturalistic outpatient settings. We analyzed 2-year follow-up data collected through Routine Outcome Monitoring (ROM) in a naturalistic sample of 917 outpatients in psychiatric specialty care in order to identify factors predicting outcome. We included patients with panic disorder with or without agoraphobia, agoraphobia without panic, social phobia, or generalized anxiety disorder. Main findings from Cox regression analyses demonstrated that several socio-demographic variables (having a non-Dutch ethnicity [HR = 0.71)], not having a daily occupation [HR = 0.76]) and clinical factors (having a diagnosis of agoraphobia [HR = 0.67], high affective lability [HR = 0.80] and behavior problems [HR = 0.84]) decreased chances of response (defined as 50% reduction of anxiety severity) over the period of two years. Living with family had a protective predictive value [HR = 1.41]. These results may imply that factors that could be thought to limit societal participation, are associated with elevated risk of poor outcome. A comprehensive ROM screening process at intake may aid clinicians in the identification of patients at risk of chronicity.

Abstract
AIMS To establish the 3-year persistency rate of alcohol use disorder (AUD) and its predictors, and to examine drinking patterns of recently remitted individuals. DESIGN AND SETTING The Netherlands Mental Health Survey and Incidence Study-2 (NEMESIS-2) surveyed a nationally representative sample of adults (aged 18-64 years) at baseline (response = 65.1%) and 3-year follow-up (response = 80.4%). PARTICIPANTS People with AUD at baseline, as defined by DSM-5 (n = 198). MEASUREMENTS AUD, drinking patterns and mental disorders were assessed using the Composite International Diagnostic Interview 3.0. Other predictors were assessed with an additional questionnaire. Predictors of persistency were examined with univariable and multivariable logistic regression analyses. RESULTS The AUD persistency rate was 29.5% [95% confidence intervals (CI) = 20.0-39.0]. In the multivariable model, the older (25-34 and 35-44) age groups had lower AUD persistency [odds ratio (OR) = 0.05; 95% CI = 0.00-0.49 and OR = 0.14; 95% CI = 0.02-0.79, respectively] than the youngest age group (18-24). A higher number of weekly drinks and a comorbid anxiety disorder predicted AUD persistency (OR = 1.03; 95% CI = 1.00-1.07 and OR = 4.56; 95% CI = 1.04-20.06, respectively). Furthermore, remission was associated with a reduction of six drinks per week between T0 and T1 . It should be noted, however, that 35.8% (95% CI = 22.4-49.2) of people in diagnostic remission still drank more than the recommended maximum (more than seven/14 drinks weekly for women/men). CONCLUSIONS Only a minority of people in the Netherlands with alcohol use disorder as defined by DSM-5 still have the disorder 3 years later. Factors that help to identify people at risk of alcohol use disorder persistence are: younger age, a higher number of weekly drinks and a comorbid anxiety disorder. A substantial number of people recently in diagnostic remission still drink above the maximum recommended level.

Abstract
BACKGROUND Naltrexone (NTX) is underutilized in clinical treatment settings because its efficacy is modest, and it is not effective for all alcoholics and, when it is effective, a significant number of alcoholics fail to maintain initial treatment gains and subsequently relapse to heavy drinking. This has slowed acceptance of NTX by the treatment community, and there is a clear need for additional treatments for alcoholism and alcohol use disorders. Given that NTX and prazosin can each reduce alcohol drinking in rats selectively bred for alcohol preference and high voluntary alcohol drinking (alcohol-preferring "P" rats), we tested whether a combination of NTX + prazosin is more effective in decreasing alcohol drinking than is either drug alone. METHODS P rats were given access to a 15% (v/v) alcohol solution for 2 hours daily. Rats were fed NTX and prazosin, alone or in combination, prior to onset of the daily 2-hour alcohol access period for 4 weeks and the effect of drug treatment on alcohol and water intake was assessed. RESULTS During the first week of treatment, neither a low dose of NTX, nor prazosin, was effective in decreasing alcohol intake when each drug was administered alone, but combining the 2 drugs in a single medication significantly reduced alcohol intake. The combination was as effective as was a higher dose of NTX. Using a low dose of NTX in combination with prazosin may reduce the potential for undesirable side effects early in treatment which, in turn, may improve patient compliance and result in a more successful outcome when NTX is used for treating alcoholism and alcohol use disorders. CONCLUSIONS Combining low-dose NTX and prazosin in a single medication may be more useful than is either drug alone for treating both inpatient and outpatient alcoholics and heavy drinkers early in the treatment process.

Abstract
Research consistently documents the negative effects of work-family conflict; however, little research focuses on alcohol use. This study embraces a tension reduction theory of drinking, wherein alcohol use is thought to reduce the negative effects of stress. The purpose of the study was to test a moderated mediation model of the relationship between work-family conflict and alcohol use in a Chicagoland community sample of 998 caregivers. Structural equation models showed that distress mediated the relationship between work-family conflict and alcohol use. Furthermore, tension reduction expectancies of alcohol exacerbated the relationship between distress and alcohol use. The results advance the study of work-family conflict and alcohol use, helping explain this complicated relationship using sophisticated statistical techniques. Implications for theory and practice are discussed.

Abstract
BACKGROUND This study examined whether prazosin reduces alcohol drinking over the course of prolonged treatment and whether it blocks the initiation of alcohol drinking in rats with a genetic predisposition toward high alcohol drinking, that is alcohol-preferring (P) rats. METHODS In study one, alcohol-experienced P rats that had been drinking alcohol for 2 h/d for several months were treated daily with prazosin (0, 0.5, 1.0, or 2.0 mg/kg body weight [BW]) for 7 weeks. In study two, alcohol-naïve P rats were treated daily with prazosin (0, 1.0, or 2.0 mg/kg BW) for 2 weeks prior to, or concomitantly with, the initiation of alcohol access and throughout 3 weeks of alcohol availability. Prazosin treatment and alcohol access were then discontinued for 2 weeks followed by reinstatement of alcohol access without prazosin treatment for 4 weeks, followed by resumption of daily prazosin treatment (2.0 mg/kg BW) for 3 weeks. RESULTS Prazosin reduced alcohol drinking throughout 7 weeks of treatment in P rats accustomed to drinking alcohol. Following termination of prazosin treatment, alcohol drinking slowly returned to pretreatment baseline. Reduced alcohol intake was accompanied by increased water intake. In alcohol-naïve P rats, prazosin administration prior to the first opportunity to drink alcohol and throughout 3 weeks of alcohol access retarded acquisition of alcohol drinking and reduced the amount of alcohol consumed. When prazosin was administered concomitantly with the first opportunity to drink alcohol, it abolished acquisition of alcohol drinking. Discontinuation of prazosin treatment allowed expression of a genetic predisposition toward high alcohol drinking to gradually emerge. Prazosin retained the ability to reduce alcohol intake with repeated treatments. CONCLUSIONS Prazosin decreased alcohol drinking during prolonged treatment and may be useful for treating alcoholism and alcohol-use disorders. Prazosin may also be useful for deterring the initiation of drinking in individuals with a family history of alcoholism.

Abstract
BACKGROUND Although the adverse consequences of comorbid panic disorder (PD) and alcohol dependence (AD) are well-established, relatively little is known about the mechanisms underlying their co-occurrence. Several researchers have postulated that alcohol's ability to dampen response to unpredictable threat may be an important motivational factor in comorbid PD and AD. To date, no research has examined these processes using a clinical sample and it is unclear whether individuals with PD and AD evidence different reactivity to unpredictable threat relative to individuals with PD-only. METHODS The aim of the current study was to examine differences in aversive responding during predictable and unpredictable threat-of-shock in three groups of individuals with: (1) current PD and remitted AD (PD and AD), (2) current PD but no lifetime diagnosis of AD (PD-only), and (3) no lifetime diagnoses of PD or AD (controls). Aversive responding was assessed using a well-established electromyography (EMG) startle paradigm. RESULTS Results indicated that PD and AD individuals evidenced greater startle potentiation during unpredictable (but not predictable) threat relative to controls and PD-only individuals (who did not differ). CONCLUSIONS These findings suggest that heightened reactivity to unpredictable threat may be an important process in PD and AD comorbidity and a possible key motivational factor underlying engagement in alcohol use.

Abstract
Background Visual height intolerance occurs when a visual stimulus causes apprehension of losing balance and falling from some height. Affecting one-third of the population, it has a broad spectrum of symptoms, ranging from minor distress to fear of heights, which is defined as a specific phobia. Specific phobias are associated with higher alcohol consumption. This has not been specifically shown for susceptibility to the more general visual height intolerance. Methods Representative case-control study nested within a population-based cross-sectional telephone survey to assess epidemiologically 1253 individuals ≥14 years, using a questionnaire on sociodemographic data, typical symptoms, precipitating visual stimuli, and alcohol drinking patterns (overall frequency of alcohol consumption, the daily quantities, and the motives). Results Individuals susceptible or nonsusceptible to visual height intolerance showed no significant differences in drinking patterns. The daily average alcohol consumption was slightly higher in persons susceptible to visual height intolerance (4.1 g/day vs. 3.7 g/day). Of those consuming alcohol, cases and controls reported on average consuming 2.3 glasses per day. The prevalence of visual height intolerance was insignificantly higher in the small minority of those drinking 2-3 times per week versus teetotalers. Conclusions Our study does not provide evidence that visual height intolerance - contrary to various specific phobias - is significantly associated with individual alcohol consumption patterns.

Abstract
The high comorbidity of alcohol use disorders (AUD) and social anxiety disorder (SAD) is often explained by excessive drinking in social situations to self-medicate social anxiety. Indeed, the motive to drink alcohol to lower social fears was found to be elevated in socially anxious persons. However, this social anxiety specific motive has not been directly investigated in primarily alcohol dependent individuals. We explored social anxiety, the motivation to drink alcohol in order to cope with social fears, and social anxiety as a consequence of drinking in AUD with and without comorbid SAD. Male AUD inpatients with (AUD+SAD group, N=23) and without comorbid SAD (N=37) completed a clinical interview and a questionnaire assessment. AUD+SAD patients reported higher levels of depression and an elevated motive to drink due to social anxiety but did not experience more social fears as a consequence of drinking. Previous results concerning alcohol drinking motives in order to relieve social fears could be replicated in a clinical AUD sample. Additionally, our findings suggest comorbid AUD+SAD patients to be more burdened regarding broader psychopathological symptoms. Thus, accessibility to SAD-specific screening and treatment procedures may be beneficial for primary AUD patients.

Abstract
Aims This study aimed to test the efficacy of integrated cognitive behaviour therapy (CBT) for coexisting post traumatic stress disorder (PTSD) and alcohol use disorders (AUD). Setting Clinics across Sydney, Australia.Design Randomized controlled trial of 12 once-weekly individual sessions of either integrated CBT for PTSD and AUD(integrated therapy, IT; n = 33) or CBT for AUD plus supportive counselling (alcohol-support, AS; n = 29). Blind assessments were conducted at baseline and post-treatment and at 5 [standard deviation (SD) = 2.25] and 9.16(SD = 3.45) months post-treatment. Participants Sixty-two adults with concurrent PTSD and AUD. Measurements Outcomes included changes in alcohol consumption (time-line follow-back), PTSD severity [clinician-administered PTSD scale (CAPS)], alcohol dependence and problems, and depression and anxiety. Findings Reductions in PTSD severity were evident in both groups. IT participants who had received one or more sessions of exposure therapy exhibited a twofold greater rate of clinically significant change in CAPS severity at follow-up than AS participants [IT60%, AS 39%, odds ratio (OR): 2.31, 95% confidence interval (CI): 1.06, 5.01]. AS participants exhibited larger reductions than IT participants in alcohol consumption, dependence and problems within the context of greater treatment from other services during follow-up. Results lend support to a mutually maintaining effect between AUD and PTSD. Conclusions Individuals with severe and complex presentations of coexisting post-traumatic stress disorder(PTSD) and alcohol use disorders (AUD) can derive substantial benefit from cognitive behaviour therapy targeting AUD, with greater benefits associated with exposure for PTSD. Among individuals with dual disorders, these therapies can generate significant, well-maintained treatment effects on PTSD, AUD and psychopathology.

Abstract
BACKGROUND Alcohol use disorders and social anxiety disorder are common and disabling conditions that frequently co-exist. Although there are efficacious treatments for each disorder, only two randomized controlled trials of interventions for these combined problems have been published. We developed a new integrated treatment for comorbid Social Anxiety Disorder and Alcohol Use Disorder based on established Motivational Interviewing (MI) and Cognitive Behaviour Therapy (CBT) interventions for the separate disorders. Compared to established MI/CBT for alcohol use disorders this new intervention is hypothesised to lead to greater reductions in symptoms of social anxiety and alcohol use disorder and to produce greater improvements in quality of life. Higher levels of alcohol dependence will result in relatively poorer outcomes for the new integrated treatment. METHODS/DESIGN A randomised controlled trial comparing 9 sessions of individual integrated treatment for alcohol and social phobia with 9 sessions of treatment for alcohol use problems alone is proposed. Randomisation will be stratified for stable antidepressant use. Post treatment clinical assessments of alcohol consumption and diagnostic status at 3 and 6 month follow-up will be blind to allocation. DISCUSSION The proposed trial addresses a serious gap in treatment evidence and could potentially define the appropriate treatment for a large proportion of adults affected by these problems.

Abstract
OBJECTIVE We hypothesized that individuals who are unable to effectively regulate emotional reactivity, which we operationalized as variability in self-reported affect throughout the day, would use alcohol more frequently and would report higher levels of drinking to cope. Further, we hypothesized that affect variation would be a stronger predictor of alcohol use or drinking to cope than level of negative affect. METHOD A total of 86 college-age students (53% female, 77% White) participated in an intensive longitudinal study for 28 days. Participants reported positive and negative affect thrice daily and reported alcohol use once daily. Participant coping motives were assessed at study initiation. RESULTS Affect variability predicted increased drinking frequency and higher levels of self-reported drinking to cope. Mean level of negative affect was not related to an increased probability of drinking, nor was it related to self-reported drinking to cope. Both individual differences in affect variation and intra-individual daily fluctuations in affect were associated with an increased likelihood of drinking. CONCLUSIONS Our results imply that individuals with higher-than-average levels of affect variation are at risk for high levels of alcohol involvement and that people are more likely to drink on days characterized by higher-than-normal levels of fluctuation in affect. Future studies on self-medication should consider negative affect variability in addition to-or instead of-level of negative affect.

Abstract
OBJECTIVE Treatment for alcohol use disorder (AUD) is far less effective for those with a co-occurring anxiety disorder. Surprisingly, adding an independent anxiety treatment to AUD treatment does not substantially improve the poor alcohol outcomes of these patients. This may reflect the lack of attention from independent treatments to the dynamic interaction of anxiety symptoms with alcohol use and drinking motivation. On the basis of this view, we assembled a cognitive behavioral therapy (CBT) program designed to both reduce anxiety symptoms and weaken the links between the experience of anxiety and the motivation to drink. METHOD 344 patients undergoing residential AUD treatment with current social phobia, generalized anxiety disorder, or panic disorder were randomly assigned to receive either the CBT or an active comparison treatment, progressive muscle relaxation training (PMRT). Assessments took place immediately following treatment and 4 months later (n = 247). RESULTS As predicted, the CBT group demonstrated significantly better alcohol outcomes 4 months following treatment than did the PMRT group. Although both groups experienced a substantial degree of anxiety reduction following treatment, there were no significant group differences immediately after treatment and only a slight advantage for the CBT group 4 months after treatment. CONCLUSIONS These findings suggest that specific interventions aimed at weakening the association between the experience of anxiety and drinking motivation play an important role in improving the alcohol outcomes of these difficult-to-treat patients beyond that of anxiety reduction alone.

Abstract
Chronic exposure to stress has many deleterious effects on behavior, which can often lead to self-medication with anxiolytics, antidepressants, or alcohol. We determined the effects of alcohol administration following a stressor on established behavioral, physiological, and neural responses to stress. Male Sprague-Dawley rats received: No alcohol/No stress (CON), Alcohol alone (ALC), Stress alone (STR), or Stress plus Alcohol (STR+ALC). For seven consecutive days, two cohorts received an oral dose of 2.0 g/kg of either 20% ethanol or saline. In Cohort 1, behavioral testing began after the final treatment (day-8). Memory was tested using the object recognition (OR) and Y-maze, anxiety on the plus maze, and depression on the forced swim task. Memory on OR and Y-maze tasks was impaired in the ALC and STR groups. This deficit was reversed in the STR+ALC group, which performed not differently from the CON group. Stress alone was associated with increased anxiety, which was alleviated with alcohol treatment. No treatment effects were found in the forced swim task. In Cohort 2, hippocampal GABAα4 was upregulated in the STR+ALC group and GluN2B was upregulated in the ALC and STR+ALC groups. The STR+ALC group in Cohort 1 showed enhanced corticosterone levels after forced swim. The STR+ALC group in Cohort 2 showed increased corticosterone levels on day-1 of treatment and a habituation by day-7. In conclusion, this study found a reversal of stress-induced deficits in cognition and anxiety when alcohol was given post-stress, and changes in neurotransmitter receptor expression may contribute to these behavioral effects.

Abstract
OBJECTIVE To examine prevalences of substance use disorders (SUD) and comprehensive patterns of comorbidities among psychiatric patients ages 18-64 years (N = 40,099) in an electronic health records (EHR) database. METHOD DSM-IV diagnoses among psychiatric patients in a large university system were systematically captured: SUD, anxiety (AD), mood (MD), personality (PD), adjustment, childhood-onset, cognitive/dementia, dissociative, eating, factitious, impulse-control, psychotic (schizophrenic), sexual/gender identity, sleep, and somatoform diagnoses. Comorbidities and treatment types among patients with a SUD were examined. RESULTS Among all patients, 24.9% (n = 9984) had a SUD, with blacks (35.2%) and Hispanics (32.9%) showing the highest prevalence. Among patients with a SUD, MD was prevalent across all age groups (50.2-56.6%). Patients aged 18-24 years had elevated odds of comorbid PD, adjustment, childhood-onset, impulse-control, psychotic, and eating diagnoses. Females had more PD, AD, MD, eating, and somatoform diagnoses, while males had more childhood-onset, impulse-control, and psychotic diagnoses. Blacks had greater odds than whites of psychotic and cognitive/dementia diagnoses, while whites exhibited elevated odds of PA, AD, MD, childhood-onset, eating, somatoform, and sleep diagnoses. Women, blacks, and Native American/multiple-race adults had elevated odds of using inpatient treatment; men, blacks, and Hispanics had increased odds of using psychiatric emergency care. Comorbid MD, PD, adjustment, somatoform, psychotic, or cognitive/dementia diagnoses increased inpatient treatment. CONCLUSION Patients with a SUD, especially minority members, use more inpatient or psychiatric emergency care than those without. Findings provide evidence for research on understudied diagnoses and underserved populations in the real-world clinical settings.

Abstract
BACKGROUND Although alcohol use disorders and anxiety disorders are highly comorbid, the relationship between these 2 disorders is not fully understood. Previous work from our laboratory shows that anxiety-like behavior is highly variable in outbred Long-Evans rats and is related to the level of voluntary ethanol (EtOH) consumption, suggesting that basal anxiety state influences EtOH intake. To further examine the relationship between the acquisition of EtOH consumption and anxiety phenotype, Long-Evans rats were assessed for anxiety-like behavior and neuronal activation following voluntary EtOH consumption in a limited access drinking paradigm. METHODS Rats were allowed to self-administer EtOH (6% v/v) for 4 days using a limited access drinking in the dark paradigm and divided into high- and low-drinking groups based on a median split of average daily EtOH intake. Immediately following the fourth drinking session, animals were tested on the elevated plus maze and evaluated for anxiety-like behaviors. Fos immunoreactivity was assessed in the central and basolateral amygdala, as well as the bed nucleus of the stria terminalis. RESULTS High EtOH drinkers spent significantly more time on the open arms of the plus maze than low EtOH drinkers. High EtOH drinkers also had increased locomotor activity as compared to both low EtOH drinkers and water drinkers. Fos immunoreactivity was positively correlated with EtOH consumption in all brain regions examined, although Fos-positive cell counts were only significantly different between high and low EtOH drinkers in the central amygdala (CeA). CONCLUSIONS Our findings demonstrate that outbred rats will voluntarily consume behaviorally effective doses of EtOH in a short-term access model and EtOH consumption is positively correlated with increased neuronal activation in the CeA.

Abstract
Prenatal ethanol exposure significantly increases later predisposition for alcohol intake, but the mechanisms associated with this phenomenon remain hypothetical. This study analyzed (Experiment 1) ethanol intake in adolescent inbred WKAH/Hok Wistar rats prenatally exposed to ethanol (2.0g/kg) or vehicle, on gestational days 17-20. Subsequent Experiments (2, 3 and 4) tested several variables likely to underlie the effect of gestational ethanol on adolescent ethanol preference, including ethanol-induced locomotor activation (LMA), ethanol-induced emission of ultrasonic vocalizations (USVs) after exposure to a rough exteroceptive stimulus, and induction of the immediate early gene C-fos in brain areas associated with processing of reward stimuli and with the retrieval and extinction of associative learning. Prenatal ethanol induced a two-fold increase in ethanol intake. Adolescents exhibited significant ethanol-induced LMA, emitted more aversive than appetitive USVs, and postnatal ethanol administration significantly exacerbated the emission of USVs. These effects, however, were not affected by prenatal ethanol. Adolescents prenatally exposed to ethanol as fetuses exhibited reduced neural activity in infralimbic cortex (but not in prelimbic cortex or nucleus accumbens core or shell), an area that has been implicated in the extinction of drug-mediated associative memories. Ethanol metabolism was not affected by prenatal ethanol. Late gestational exposure to ethanol significantly heightened drinking in the adolescent offspring of an inbred rat strain. Ethanol-induced LMA and USVs were not associated with differential ethanol intake due to prenatal ethanol exposure. Prenatal ethanol, however, altered basal neural activity in the infralimbic prefrontal cortex. Future studies should analyze the functionality of medial prefrontal cortex after prenatal ethanol and its potential association with predisposition for heightened ethanol intake.

Social housing and alcohol drinking in male-female pairs of prairie voles (Microtus ochrogaster). Psychopharmacology (Berl) 2012; 224:121-32.

Abstract
RATIONALE Social environment influences alcohol consumption in humans; however, animal models have only begun to address biological underpinnings of these effects. OBJECTIVES We investigated whether social influences on alcohol drinking in the prairie vole are specific to the sex of the social partner. METHODS In Experiment 1, control, sham, and gonadectomized voles were placed either in mesh-divided housing with a same-sex sibling or isolation with access to ethanol. In Experiment 2, animals were given an elevated plus maze test (EPM) and then females were paired with a castrated male followed by isolation or mesh-divided housing with access to ethanol. In Experiment 3, subjects categorized as low or high drinkers based on initial ethanol intake were placed in mesh-divided housing with an opposite-sex partner of the same or opposite drinking group and ethanol access. Subjects were then moved back to isolation for a final ethanol access period. RESULTS Same-sex pairs showed social facilitation of drinking similar to previous reports. Gonadectomy did not affect alcohol drinking. Opposite-sex paired animals in Experiment 2 did not differ in alcohol drinking based on social housing. EPM measures suggested a relationship between anxiety-like behaviors and drinking that depended on social environment. Experiment 3 identified moderate changes in alcohol preference based on social housing, but these effects were influenced by the animal's own drinking behavior and were independent of their partner's drinking. CONCLUSIONS Social influences on alcohol self-administration in prairie voles differ based on the sex of a social partner, consistent with human drinking behavior.

Abstract
BACKGROUND The neuropeptide, oxytocin (OT), has been reported to block tolerance formation to alcohol and decrease withdrawal symptoms in alcohol-dependent rodents. Numerous recent studies in human subjects indicate that OT administered by the intranasal route penetrates into and exerts effects within the brain. METHODS In a randomized, double-blind clinical trial, intranasal OT (24 IU/dose, N = 7) or placebo (N = 4) was given twice daily for 3 days in alcohol-dependent subjects admitted to a research unit for medical detoxification using Clinical Institute Withdrawal Assessment for Alcohol (CIWA) score-driven PRN administration of lorazepam. Subjects rated themselves on the Alcohol Withdrawal Symptom Checklist (AWSC) each time CIWA scores were obtained. Subjects also completed the Penn Alcohol Craving Scale, an Alcohol Craving Visual Analog Scale (ACVAS) and the Profile of Mood States (POMS) on inpatient days 2 and 3. RESULTS All subjects had drunk heavily each day for at least 2 weeks prior to study and had previously experienced withdrawal upon stopping/decreasing alcohol consumption. OT was superior to placebo in reducing alcohol withdrawal as evidenced by: less total lorazepam required to complete detoxification (3.4 mg [4.7, SD] vs. 16.5 [4.4], p = 0.0015), lower mean CIWA scores on admission day 1 (4.3 [2.3] vs. 11.8 [0.4], p < 0.0001) and day 2 (3.4 [2.2] vs. 11.1 [3.6], p < 0.002), lower AWSC scores on days 1 and 2 (p < 0.02; p = 0.07), and lower ACVAS ratings (p = 0.01) and lower POMS Tension/Anxiety subscale scores on day 2 (p < 0.01). CONCLUSIONS This is the first demonstration that OT treatment may block alcohol withdrawal in human subjects. Our results are consistent with previous findings in rodents that OT inhibits neuroadaptation to and withdrawal from alcohol. OT could have advantages over benzodiazepines in managing alcohol withdrawal because it may reverse rather than maintain sedative-hypnotic tolerance. It will be important to test whether OT treatment is effective in reducing drinking in alcohol-dependent outpatients.

Abstract
The aim of this study was to assess the prevalence of hazardous and harmful alcohol use and associated factors among patients with tuberculosis in South Africa. In a cross-sectional survey new tuberculosis (TB) and TB retreatment patients were consecutively screened using the Alcohol Use Disorder Identification Test (AUDIT) within one month of anti-tuberculosis treatment. The sample included 4,900 (54.5% men and women 45.5%) tuberculosis patients from 42 primary care clinics in three districts. Results indicate that, overall 23.2% of the patients were hazardous or harmful alcohol drinkers, 31.8% of men and 13.0% of women were found to be hazardous drinkers, and 9.3% of men and 3.4% of women meet criteria for probable alcohol dependence (harmful drinking) as defined by the AUDIT. Men had significantly higher AUDIT scores than women. In multivariable analyses it was found that among men poor perceived health status, tobacco use, psychological distress, being a TB retreatment patient and not being on antiretroviral therapy (ART), and among women lower education, tobacco use and being a TB retreatment patient were associated with hazardous or harmful alcohol use. The study found a high prevalence of hazardous or harmful alcohol use among tuberculosis primary care patients. This calls for screening and brief intervention and a comprehensive alcohol treatment programme as a key component of TB management in South Africa.

Abstract
This study tested the specificity of the relationship between social anxiety disorder (SAD) and coping drinking motives (versus enhancement drinking motives and social drinking motives) within the context of a range of potentially confounding variables measured during adolescence (e.g., quantity and frequency of alcohol use, coping drinking motives) and substantively important variables assessed during young adulthood (e.g., other anxiety disorders and major depressive disorder). A sample of high school sophomores and juniors (n=717) completed measures of substance use and risk factors during adolescence and were then prospectively followed-up in early- and middle-young adulthood, and psychiatric diagnoses and drinking motives (i.e., coping, enhancement, and social) were assessed each time. Findings indicated that SAD was specifically related to coping motives (measured during early-to-middle young adulthood) after controlling for the effects of a range of alcohol and mental health variables. In addition, adolescent variables predicted young adult drinking motives as did major depressive disorder and other anxiety disorders. These findings are discussed within a conceptual framework of the functional role (e.g., self-medication) that drinking motives, and especially coping drinking motives, may play in the etiology of alcohol problems and disorders. Implications for prevention and treatment interventions are discussed.

Abstract
BACKGROUND Phobic disorders are highly prevalent and constitute a considerable burden for patients and society. As patients wait for face-to-face psychotherapy for phobic disorders in outpatient clinics, this time can be used for guided self-help interventions. The aim of this study is to investigate a five week internet-based guided self-help programme of exposure therapy in terms of clinical effectiveness and impact on speed of recovery in psychiatric outpatients, as well as the cost-effectiveness of this pre-treatment waiting list intervention. METHODS/DESIGN A randomised controlled trial will be conducted among 244 Dutch adult patients recruited from waiting lists of outpatient clinics for face-to-face psychotherapy for phobic disorders. Patients suffering from at least one DSM-IV classified phobic disorder (social phobia, agoraphobia or specific phobia) are randomly allocated (at a 1:1 ratio) to either a five-week internet-based guided self-help program followed by face-to-face psychotherapy, or a control group followed by face-to-face psychotherapy. Waiting list status and duration are unchanged and actual need for further treatment is evaluated prior to face-to-face psychotherapy. Clinical and economic self-assessment measurements take place at baseline, post-test (five weeks after baseline) and at 3, 6, 9 and 12 months after baseline. DISCUSSION Offering pre-treatment internet-based guided self-help efficiently uses time otherwise lost on a waiting list and may increase patient satisfaction. Patients are expected to need fewer face-to-face sessions, reducing total treatment cost and increasing speed of recovery. Internet-delivered treatment for phobias may be a valuable addition to psychotherapy as demand for outpatient treatment increases while budgets decrease.

Abstract
Use of complementary medicines and therapies (CAM) and modification of lifestyle factors such as physical activity, exercise, and diet are being increasingly considered as potential therapeutic options for anxiety disorders. The objective of this metareview was to examine evidence across a broad range of CAM and lifestyle interventions in the treatment of anxiety disorders. In early 2012 we conducted a literature search of PubMed, Scopus, CINAHL, Web of Science, PsycInfo, and the Cochrane Library, for key studies, systematic reviews, and metaanalyses in the area. Our paper found that in respect to treatment of generalized anxiety or specific disorders, CAM evidence revealed current support for the herbal medicine Kava. One isolated study shows benefit for naturopathic medicine, whereas acupuncture, yoga, and Tai chi have tentative supportive evidence, which is hampered by overall poor methodology. The breadth of evidence does not support homeopathy for treating anxiety. Strong support exists for lifestyle modifications including adoption of moderate exercise and mindfulness meditation, whereas dietary improvement, avoidance of caffeine, alcohol, and nicotine offer encouraging preliminary data. In conclusion, certain lifestyle modifications and some CAMs may provide a beneficial role in the treatment of anxiety disorders.

Abstract
BACKGROUND Rodent studies have demonstrated that adolescent social isolation results in many behavioral perturbations, including increases in anxiety-like behaviors. Socially isolated (SI) rats have also been shown to self-administer greater amounts ethanol (EtOH) in some, but not all, studies. Here, we tested whether juvenile social isolation increases EtOH drinking using an intermittent procedure that engenders relatively high intake in normally reared animals. We also compared the behavioral phenotype of rats reared under social isolation or group-housed conditions with adult rats housed under conditions commonly used in EtOH-drinking studies. METHODS Male Long Evans rats were procured immediately postweaning and were group housed for 1 week. Subjects were then randomly divided into 2 groups: SI rats, housed individually for 6 weeks and group-housed (GH) rats (4/cage). A third group was procured as young adults and was housed individually upon arrival for 1 week (standard housing condition). Rats were then tested in a plus-maze and novelty assay, and then, all subjects were singly housed and EtOH drinking was assessed. RESULTS SI rats displayed increased anxiety-like behaviors on the plus-maze, a greater locomotor response to a novel environment, and increased EtOH intake, relative to GH rats. Age-matched standard housed (STD) rats exhibited an anxiety-like behavioral profile on the plus-maze that was similar to SI, and not GH rats, and also drank EtOH at levels comparable with SI subjects. In addition, anxiety-like behavior on the plus-maze correlated with intermittent EtOH intake in SI and GH rats. CONCLUSIONS These data further support the validity of the rodent juvenile social isolation model for studies directed at elucidating behavioral and neurobiological mechanisms linking anxiety and EtOH drinking. These findings further suggest that housing conditions commonly employed in rodent drinking studies may recapitulate the anxiety-like and EtOH-drinking phenotype engendered by a juvenile social isolation procedure.
