Alterations to chromatin structure induced by environmental insults have become an attractive explanation for the persistence of exposure effects into subsequent life stages. However, a growing body of work examining the epigenetic impact that alcohol and other drugs of abuse exert consistently notes a disconnection between induced changes in chromatin structure and patterns of gene transcription. Thus, an important question is whether perturbations in the 'histone code' induced by prenatal exposures to alcohol implicitly subvert gene expression, or whether the hierarchy of cellular signaling networks driving development is such that they retain control over the transcriptional program...

Critical analyses of drug use and 'addiction' have identified a series of binary oppositions between addiction and free will, independence, self-control, responsibility, productivity and autonomy. This critical work has also examined how science, policy and popular discourses frequently characterise addiction as antithetical to health and well-being. Furthermore, those diagnosed with addiction are often understood as indifferent to health and well-being, or as lacking the knowledge or desire required to maintain them...

The review examines Attention Deficit Hyperactivity Disorder (ADHD in its Child and Adult form) and its various presentations (Hyperactive Impulsive, Inattentive, and Combined) with a particular focus on environmental (incl. social factors), lifestyles and comorbidities. It is argued that ADHD is best understood in a holistic and interactive context and a vast empirical literature is presented to illustrate the point: Environmental factors include stress in general as well as exposure to toxins (phthalates, bisphenol A)...

BACKGROUND: Globally, the second leading cause of death among adolescents is suicide and in middle-income countries adolescents' suicidal ideation is a neglected public health area. The present study was conducted to determine the prevalence and correlates of suicidal ideation among 15-17-year-old high school students in Iran. METHODS: Self-administered, Global School-based Student Health Survey (GSHS) questionnaires were distributed to a representative sample (N =1517) of high-school students aged 15-17 in the city of Tabriz...

We recently characterized S426A/S430A mutant mice expressing a desensitization-resistant form of the CB1 receptor. These mice display an enhanced response to endocannabinoids and ∆9-THC. In this study, S426A/S430A mutants were used as a novel model to test whether ethanol consumption, morphine dependence, and reward for these drugs are potentiated in mice with a "hyper-sensitive" form of CB1. Using an unlimited-access, two-bottle choice, voluntary drinking paradigm, S426A/S430A mutants exhibit modestly increased intake and preference for low (6%) but not higher concentrations of ethanol...

INTRODUCTION AND AIMS: We previously found that residential rehabilitation increased continuous abstinence from methamphetamine use 1 year after treatment. We examine what client and treatment characteristics predict this outcome. DESIGN AND METHODS: Participants (n = 176) were dependent on methamphetamine and entering residential rehabilitation for methamphetamine use. Simultaneous logistic regression was used to identify independent predictors of continuous abstinence from methamphetamine use at 1 year follow-up...

By considering the debilitating outcome of co-occurring of bipolar disorder (BD) and substance abuse, determination of risk factors of substance use disorders (SUD: abuse or dependence of drugs and/or alcohol) is essential to identify the susceptible patients. The purpose of this study was to clarify the major determinant factors of SUD among adults with BD by reviewing the relevant literature. We systematically searched electronic databases including PubMed (MEDLINE), EMBASE, OVID, Cochrane and Scopus for human studies addressing the co-existence of bipolar disorder and SUD...

Although research on alcohol policy has produced a huge international literature, alcohol research and policy itself-its cultural assumptions, methods, politics and ethics-has rarely been subject to critical analysis. In this article, I provide an appreciative review of an exception to this trend: Joseph Gusfield's 1981 classic, The Culture of Public Problems: Drinking-Driving and the Symbolic Order. I first outline Gusfield's argument that the 'problem of drinking-driving' is constructed as a 'drama of individualism' centring on the 'killer drunk'...

INTRODUCTION AND AIMS: New psychoactive substances (NPS) have hedonic effects that may lead to dependence. Headshops selling NPS increased in number in Ireland from late 2009. Legislation was enacted in May and August of 2010 that caused their closure. It is unknown whether such events impact the rate of NPS use disorders. DESIGNS AND METHODS: We conducted a population-based study using the Irish national database of episodes of addiction treatment between 2009 and 2012...

BACKGROUND: We conducted a genome-wide gene × environment interaction analysis to identify genetic variants that interact with cannabis dependence (CaD) in influencing risky sexual behaviours (RSB). METHODS: Our sample included cannabis-exposed and sexually experienced African-American and European-American participants. A DSM-IV CaD diagnosis and RSB were evaluated using the Semi-Structured Assessment for Drug Dependence and Alcoholism. We analyzed RSBs as a score that takes into account experiences of unprotected sex and multiple sexual partners...

Alcoholic liver disease (ALD), a leading cause of chronic liver injury worldwide, comprises a range of disorders including simple steatosis, steatohepatitis, cirrhosis, and hepatocellular carcinoma. Over the last five decades, many animal models that have been useful for the study of ALD pathogenesis have been developed. Recently, a chronic-plus-binge ethanol feeding model was reported. This model induces significant steatosis, hepatic neutrophil infiltration, and liver injury. A clinically relevant model of high-fat diet feeding plus binge ethanol was also developed, which highlights the risk of excessive binge drinking in obese/overweight individuals...

OBJECTIVE: To examine the 3-year course of multiple co-occurring substance use disorders (SUDs) based on longitudinal survey data from a large, nationally representative sample. METHODS: National estimates of the prevalence of DSM-IV SUDs were derived by analyzing data from structured, face-to-face diagnostic interviews as part of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), which collected data from a large, nationally representative sample of noninstitutionalized US adults at 2 waves (2001-2002 and 2004-2005; N = 34,653)...

BACKGROUND: The subthalamic nucleus (STN) has only recently been considered to have a role in reward processing. In rats, inactivation of the STN by lesion or high-frequency stimulation (HFS) decreases motivation for cocaine but increases motivation for sucrose. For ethanol, the effect of STN lesion depends on the individual's baseline intake; decreasing motivation for ethanol in rats with lower ethanol intake, while increasing motivation for ethanol in rats with higher-but still limited-ethanol intake...

BACKGROUND: Individuals with one psychiatric disorder are at increased risk for incidence and recurrence of other disorders. We characterize whether the magnitude of such heterotypic continuity varies based on whether the first disorder remits or persists over time. METHOD: Cohorts were selected from participants in the National Epidemiologic Survey on Alcohol and Related Conditions wave 1 (2001-2002) and wave 2 (2004-2005) surveys with ⩾1 mood, anxiety, or substance use disorder at wave 1...

BACKGROUND: Alcohol abuse is an important public health problem, frequently unrecognized among people living with HIV/AIDS (PLWHA), and requires investigation and intervention. It is usually associated with lower adherence to highly active antiretroviral therapy (HAART). It can also produce adverse clinical outcomes, such as changes in certain HIV markers, particularly CD4 cell counts and HIV viral loads (VLs). Thus, this study aimed to evaluate the prevalence of alcohol abuse among PLWHA, its associated risk factors and effects on CD4 cell counts and HIV VLs in southern Brazil...

According to prevailing neurobiological theories of addiction, altered function in neural reward circuitry is a central mechanism of alcohol dependence. Growing evidence postulates that the ventral striatum (VS), as well as areas of the prefrontal cortex, contribute to the increased incentive salience of alcohol-associated cues, diminished motivation to pursue non-drug rewards and weakened strength of inhibitory cognitive control, which are central to addiction. The present study aims to investigate the neural response and functional connectivity underlying monetary, non-drug reward processing in alcohol dependence...

Stress plays a key role in addiction etiology and relapse. Rodent models posit that following repeated periods of alcohol and other drug intoxication, compensatory allostatic changes occur in the central nervous system (CNS) circuits involved in behavioral and emotional response to stressors. We examine a predicted manifestation of this neuroadaptation in recently abstinent alcohol-dependent humans. Participants completed a translational laboratory task that uses startle potentiation to unpredictable (vs. predictable) stressors implicated in the putative CNS mechanisms that mediate this neuroadaptation...
