Preclinical and clinical evidence for suppression of alcohol intake by apremilast.

Treatment options for alcohol use disorders (AUDs) have minimally advanced since 2004, while the annual deaths and economic toll have increased alarmingly. Phosphodiesterase type 4 (PDE4) is associated with alcohol and nicotine dependence. PDE4 inhibitors were identified as a potential AUD treatment using a bioinformatics approach.

Neuropsychological performance in young adults with cannabis use disorder.

Background And Aims: Cannabis is a commonly used recreational drug in young adults. The worldwide prevalence in 18- to 25-year-olds is approximately 35%. Significant differences in cognitive performance have been reported previously for groups of cannabis users.

Should Substance Use Counselors Choose a Direction For Their Clients? Motivational Interviewing Trainers May Be Ambivalent.

Motivational Interviewing (MI) is comprised of a client-centered relationship and a clear intention on the part of the practitioner to influence behavior change. This study explores MI trainers' decisions about their use of directionality in MI as they instruct others in the method. 111 MI trainers were asked to select content they would include in a hypothetical MI training.

Alcohol Use Disorder: The Role of Medication in Recovery.

The misuse of alcohol in the United States continues to take a large toll on society, resulting in the deaths of about 88,000 Americans per year. Moreover, it is estimated that nearly 14.6 million Americans currently meet diagnostic criteria for current alcohol use disorder (AUD).

Glucocorticoid receptor modulators decrease alcohol self-administration in male rats.

Alcohol use disorder (AUD) is associated with the dysregulation of brain stress and reward systems, including glucocorticoid receptors (GRs). The mixed glucocorticoid/progesterone receptor antagonist mifepristone and selective GR antagonist CORT113176 have been shown to selectively reduce alcohol consumption in alcohol-dependent rats. Mifepristone has also been shown to decrease alcohol consumption and craving for alcohol in humans with AUD.

Effects of a high-fat diet on impulsive choice in rats.

Introduction: Obesity and binge eating disorder are associated with high levels of impulsivity, but the causal role of eating and palatable food in these associations is unclear. Studies in rodents show that a high-fat diet can increase one aspect of impulsivity (impulsive action); it is less clear, however, whether a dissociable aspect of impulsivity (impulsive choice) is similarly affected. Hence, the aim of this study was to ascertain whether chronic exposure to a high-fat diet would alter impulsive choice.

Inbred Substrain Differences Influence Neuroimmune Response and Drinking Behavior.

Background: The inbred mouse strain C57BL/6 is widely used in both models of addiction and immunological disease. However, there are pronounced phenotypic differences in ethanol (EtOH) consumption and innate immune response between C57BL/6 substrains. The focus of this study was to examine the effects of substrain on innate immune response and neuroimmune-induced escalation of voluntary EtOH consumption.

The future of translational research on alcohol use disorder.

In March 2019, a scientific meeting was held at the University of California, Los Angeles (UCLA) Luskin Center to discuss approaches to expedite the translation of neurobiological insights to advances in the treatment of alcohol use disorder (AUD). A guiding theme that emerged was that while translational research in AUD is clearly a challenge, it is also a field ripe with opportunities. Herein, we seek to summarize and disseminate the recommendations for the future of translational AUD research using four sections.

Microglia depletion and alcohol: Transcriptome and behavioral profiles.

Alcohol abuse induces changes in microglia morphology and immune function, but whether microglia initiate or simply amplify the harmful effects of alcohol exposure is still a matter of debate. Here, we determine microglia function in acute and voluntary drinking behaviors using a colony-stimulating factor 1 receptor inhibitor (PLX5622). We show that microglia depletion does not alter the sedative or hypnotic effects of acute intoxication.

Reduced Sexual Risk Behaviors Among Persons With HIV After Release From the Criminal Justice System.

Background: HIV prevalence is 3 times greater for those in the criminal justice system than the general population, with an assumed increase in sexual risk behaviors (SRBs) postrelease. HIV viral suppression impacts HIV transmission; however, studies of SRBs among persons with HIV leaving the criminal justice system are limited, and no studies have examined viral suppression in relation to SRBs in persons leaving the criminal justice system.

Methods: Data were examined from 2 double-blind placebo-controlled trials of extended-release naltrexone among persons with HIV and alcohol use or opioid use disorder.

The association between gene rs13212041 polymorphism and onset of alcohol abuse.

Background: Alcohol dependence displays a wide variety of clinical phenotypes. Various typology classifications of alcoholism include age of onset of alcohol abuse as one of the major phenotypic features. Serotonergic changes have been associated with alcoholism, while serotonin receptors type 1B (5-HT1B) play an important role in regulating serotonergic neurotransmission.

Toll-like receptor 3 dynamics in female C57BL/6J mice: Regulation of alcohol intake.

Although there are sex differences in the effects of alcohol on immune responses, it is unclear if sex differences in immune response can influence drinking behavior. Activation of toll-like receptor 3 (TLR3) by polyinosinic:polycytidylic acid (poly(I:C)) produced a rapid proinflammatory response in males that increased alcohol intake over time (Warden et al., 2019).

More than Taking a Chair: The Perceived Group Social Dynamics of Alcoholics Anonymous Related to Changes in Spiritual Practices.

Alcoholics Anonymous (AA) meeting attendance and spiritual practices are established predictors of abstinence. This study utilized longitudinal data from two studies of AA to investigate 1) how perceived within meeting social dynamics in AA meetings affect later AA attendance, and thus exposure to the emphasis of spiritual practices and 2) influence the extent that spiritual gains are mobilized, beyond AA attendance. Findings revealed that greater group cohesion was associated with lower AA attrition, and that expressiveness, or openness, of the group predicted reported practice of spiritual behaviors.

Gabapentin for the treatment of alcohol use disorder.

Alcohol misuse is the fifth leading risk factor for premature death and disability worldwide. Fewer than 10% of afflicted Americans receive pharmacological treatment for alcohol use disorder. Gabapentin is a calcium channel GABAergic modulator that is widely used for pain.

A clinical instrument to guide brief interventions for adolescents with substance use concerns.

Background: Adolescent substance use is an important public health problem in New Mexico and the United States. The New Mexico Department of Health school-based health centers (SBHCs) universally administer a validated screen, the CRAFFT (Car, Relax, Alone, Forget, Friends, Trouble), for adolescent substance use concerns; however, quality assurance efforts revealed that SBHC providers needed more information at the point of screening to initiate brief interventions for students with positive CRAFFT screens. The CHISPA (Cocaine, Heroin, IV drugs, Synthetic pot, Pot, Alcohol) was developed to gather specific information on recent substance use experience to guide brief interventions.

Association of GABAA receptor α2 subunit gene (GABRA2) with alcohol dependence-related aggressive behavior.

Alcohol dependence is a common chronic disorder precipitated by the complex interaction between biological, genetic and environmental risk factors. Recent studies have demonstrated that polymorphisms of the gene encoding the GABAA receptor α2 subunit (GABRA2) are associated with alcohol dependence in different populations of European ancestry. As aggression often occurs in the context of alcohol dependence, the aim of this study was to examine the allelic and haplotypic association of GABRA2 gene with alcohol dependence and related aggressive behavior in subjects of Eastern European (Croatian) origin.

Heavy social drinkers score higher on implicit wanting and liking for alcohol than alcohol-dependent patients and light social drinkers.

Background And Objectives: Automatic hedonic ("liking") and incentive ("wanting") processes are assumed to play an important role in addiction. Whereas some neurobiological theories suggest that these processes become dissociated when drug use develops into an addiction (i.e.

Alcohol use among reserve-dwelling adult First Nation members: use, problems, and intention to change drinking behavior.

Introduction: Although alcohol use was not part of traditional First Nation (FN) life, alcohol misuse currently poses a significant public health problem. There is a dearth of research efforts to understand both alcohol misuse and efforts to resolve these problems. The primary aims of this study were to 1) present descriptive data on alcohol use in FN adults living on one reserve in Eastern Canada; and 2) explore correlates of help seeking intentions and past behaviors.
