BACKGROUND: Self-administration is a hallmark of all addictive drugs, including alcohol. Human laboratory models of alcohol self-administration have characterized alcohol-seeking behavior, and served as surrogate measures of the effectiveness of pharmacotherapies for alcohol use disorders. Intravenous alcohol self-administration (IV-ASA) is a novel method that assess alcohol exposure driven primarily by the pharmacological response to alcohol, and may have utility in characterizing unique behavioral and personality correlates of alcohol-seeking and consumption...

BACKGROUND: Patients with bipolar disorder from the US have more early-onset illness and a greater familial loading for psychiatric problems than those from the Netherlands or Germany (abbreviated here as Europe). We hypothesized that these regional differences in illness burden would extend to the patients siblings. METHODS: Outpatients with bipolar disorder gave consent for participation in a treatment outcome network and for filling out detailed questionnaires...

BACKGROUND: Cocaine dependence has been associated with alterations in the brain's white matter integrity, yet relevant questions remain about what alterations are linked to cocaine use and/or polysubstance use, and whether they are amenable to abstinence. METHODS: This study applied a single measurement session of diffusion tensor imaging (DTI) to examine white matter structure in male cocaine polysubstance users (n=37) versus male healthy controls (n=38), along with correlations between DTI measures and patterns of polysubstance use and duration of abstinence...

This study evaluated the role of psychiatric morbidity in relation to a history of suicidal behavior, with a particular focus on attention-deficit/hyperactivity disorder (ADHD). Suicidality and psychiatric diagnoses were assessed in 370 incarcerated male juvenile delinquents from Northern Russia using the semi-structured K-SADS-PL psychiatric interview. A lifetime history of suicidal ideation only (24.7 %) and suicidal ideation with suicide attempts (15.7 %) was common. Binary logistic regression analysis was used to assess the role of ADHD and other psychiatric disorders in suicidal ideation and suicide attempts...

: It has been suggested that drug tolerance represents a form of learning and memory, but this has not been experimentally established at the molecular level. We show that a component of alcohol molecular tolerance (channel internalization) from rat hippocampal neurons requires protein synthesis, in common with other forms of learning and memory. We identify β-catenin as a primary necessary protein. Alcohol increases β-catenin, and blocking accumulation of β-catenin blocks alcohol-induced internalization in these neurons...

Benzodiazepines (BZDs) are the most widely prescribed drug class in developed countries, but they have high potential for tolerance, dependence and abuse. Cognitive deficits in long-term BZD users have long been known, but previous results might have been biased by patients' old age, coexisting neurological or psychiatric conditions or concurrent alcohol or psychotropic drug dependence. The study was aimed to explore the neuropsychological effect of high-dose BZD dependence, which represents an emerging addiction phenomenon...

Phytotherapy is an emerging field successfully utilized to treat various chronic diseases including alcohol dependence. In the present study, we examined the effect of the standardized methanolic extract of Morinda citrifolia Linn. unripe fruit (MMC), on compulsive ethanol-seeking behavior using the mouse conditioned place preference (CPP) test. CPP was established by injections of ethanol (2 g/kg, i.p.) in a 12-day conditioning schedule in mice. The effect of MMC and the reference drug, acamprosate (ACAM), on the reinforcing properties of ethanol in mice was studied by the oral administration of MMC (1, 3, and 5 g/kg) and ACAM (300 mg/kg) 60 min prior to the final CPP test postconditioning...

BACKGROUND: Few studies have employed standardized alcohol misuse measures to assess relationships with sexual risk and HIV/syphilis infections among Chinese men who have sex with men (MSM). METHODS: We conducted a cross-sectional study among MSM in Beijing during 2013-2014. An interviewer-administered survey was conducted to collect data on sociodemographics, high-risk behaviors, and alcohol use/misuse patterns (hazardous/binge drinking and risk of alcohol dependence) in the past 3 months using Alcohol Use Disorder Identification Test-Consumption (AUDIT-C)...

BACKGROUND: Alcohol use disorders are associated with single-nucleotide polymorphisms in GABRA2, the gene encoding the GABAA receptor α2-subunit in humans. Deficient GABAergic functioning is linked to impulse control disorders, intermittent explosive disorder, and to drug abuse and dependence, yet it remains unclear whether α2-containing GABAA receptor sensitivity to endogenous ligands is involved in excessive alcohol drinking. METHODS: Male wild-type (Wt) C57BL/6J and point-mutated mice rendered insensitive to GABAergic modulation by benzodiazepines (BZD; H101R), allopregnanolone (ALLO) or tetrahydrodeoxycorticosterone (THDOC; Q241M), or high concentrations of ethanol (EtOH) (S270H/L277A) at α2-containing GABAA receptors were assessed for their binge-like, moderate, or escalated chronic drinking using drinking in the dark, continuous access (CA) and intermittent access (IA) to alcohol protocols, respectively...

There are complex historical connections between sexual minoritisation and desires to chemically alter bodily experience. For gay men, drug and alcohol use can be a creative or experimental response to social marginalisation - and not necessarily a problematic one in every instance. Numerous studies have found that infection with HIV and other sexually transmissible infections (STIs) is more likely among gay and men who have sex with men (MSM) who use recreational drugs than those who do not, but the causal nature of these relations is uncertain...

Alcohol misuse has been linked to dysregulation of stress, emotion, and reward brain circuitries. A candidate key mediator of this association is the FK506-binding protein (FKBP5), a negative regulator of the glucocorticoid receptor. The aim of the present study was to further understand the Fkbp5/FKBP5-related genetic underpinnings underlying the relationship between early life social relations and alcohol drinking. The effect of maternal separation and voluntary alcohol drinking on Fkbp5 expression was investigated in the brain of young adult rats, whereas the interaction effect of the functional FKBP5 single nucleotide polymorphism rs1360780 genotype and parent-child relationship on problematic drinking was examined in young adult humans...

The purpose of this study is to assess the association between gambling severity and exposure to guns among substance-using women recruited in the community. Data for these analyses come from the baseline phase of two community-based HIV prevention interventions conducted among alcohol and drug-using women in St. Louis, MO. Gun exposure was assessed using the Violence Exposure Questionnaire (VEQ), and DSM-IV pathological gambling (PG) symptoms and other psychiatric symptoms were assessed using the Computerized Diagnostic Interview Schedule; The Composite International Diagnostic Interview Substance Abuse Module assessed DSM-IV substance dependence, including cocaine dependence and alcohol dependence...

BACKGROUND: While methicillin-resistant Staphylococcus aureus (MRSA) is increasing in prevalence globally, Sweden is still a low-prevalence country enabling studies on the natural MRSA spread in subpopulations unaffected by a surrounding highly infected population. Substance dependence and injection drug use have been risk factors for MRSA carriage and infection in other countries. In this retrospective, longitudinal register study, we investigated MRSA epidemiology 1997-2013 in opioid and amphetamine-dependent individuals, in comparison with alcohol-dependent subjects...

BACKGROUND: Despite empirical evidence supporting the use of Web-based interventions for problem drinking, much remains unknown about factors that influence their effectiveness. OBJECTIVE: We evaluated the performance of 2 resources for people who want to achieve and maintain abstinence: SMART Recovery (SR) and Overcoming Addictions (OA). OA is a Web application based on SR. We also examined participant and intervention-related factors hypothesized to impact clinical outcomes of Web-based interventions...

Traffic policies show growing concerns about driving under the influence of cannabis, since cannabinoids are one of the most frequently encountered psychoactive substances in the blood of drivers who are drug-impaired and/or involved in accidents, and in the context of a legalization of medical marijuana and of recreational use. The neurobiological mechanisms underlying the effects of cannabis on safe driving remain poorly understood. In order to better understand its acute and long-term effects on psychomotor functions involved in the short term ability and long-term fitness to drive, experimental research has been conducted based on laboratory, simulator or on-road studies, as well as on structural and functional brain imaging...

OBJECTIVE: Despite high levels of alcohol use, drug use and risky behaviors, rates of help-seeking amongst young people are typically low. This study explored the profile of young people (under the age of 25 years) completing an online screen, assessing substance use problem severity and wellbeing in comparison with adults completing the same screen, so as to inform development of better targeted approaches for this in-need population. METHODS: Between 2012 and 2014, an online alcohol and drug screen was promoted across Australia on a national online counseling service...

INTRODUCTION: Studies in laboratory animals and humans indicate that endogenous opioids play an important role in regulating the rewarding value of various drugs, including ethanol (EtOH). Indeed, opioid antagonists are currently a front-line treatment for alcoholism in humans. Although roles for mu- and delta-opioid receptors have been characterized, the contribution of kappa-opioid receptors (KORs) is less clear. There is evidence that changes in KOR system function can decrease or increase EtOH drinking, depending on test conditions...

Few studies have attempted to characterize how co-occurring risk factors for substance use disorders intersect. A recent study examined this question regarding cigarette smoking and demonstrated that co-occurring risk factors generally act independently. The present study examines whether that same pattern of independent intersection of risk factors extends to illicit drug abuse/dependence using a U.S. nationally representative sample (National Survey on Drug Use and Health, 2011-2013). Logistic regression and classification and regression tree (CART) modeling were used to examine risk of past-year drug abuse/dependence associated with a well-established set of risk factors for substance use (age, gender, race/ethnicity, education, poverty, smoking status, alcohol abuse/dependence, mental illness)...
