Loss, gain and choice difficulty in gambling patients: Neural and behavioural processes.

Impaired decision-making is often displayed by individuals suffering from gambling disorder (GD). Since there are a variety of different phenomena influencing decision-making, we focused in this study on the effects of GD on neural and behavioural processes related to loss aversion and choice difficulty. Behavioural responses as well as brain images of 23 patients with GD and 20 controls were recorded while they completed a mixed gambles task, where they had to decide to either accept or reject gambles with different amounts of potential gain and loss.

Education and Training in Addiction Medicine and Psychology across Europe: A EUFAS Survey.

Introduction: Training in addiction medicine and addiction psychology is essential to ensure the quality of treatment for patients with substance use disorders. Some earlier research has shown varying training between countries, but no comprehensive study of addiction training across Europe has been performed. The present study by the European Federation for Addiction Societies (EUFAS) aimed to fill this gap.

Phosphatidylethanol (PEth) for Monitoring Sobriety in Liver Transplant Candidates: Preliminary Results of Differences Between Alcohol-Related and Non-Alcohol-Related Cirrhosis Candidates.

BACKGROUND Monitoring sobriety is mandatory for liver transplant (LT) candidates with alcohol-related cirrhosis in Germany. Prior to listing, abstinence of 6 months is required. However, little is known about biomarker performance in alcohol-related cirrhosis.

German Guidelines on Screening, Diagnosis, and Treatment of Alcohol Use Disorders: Update 2021.

Introduction: Alcohol consumption in Germany is associated with considerable health and economic consequences. In addition to prevention, the early detection and differential treatment of those affected play an important role. The guideline "Screening, Diagnosis, and Treatment of Alcohol Use Disorders" forms the basis of this care for people suffering from alcohol use disorders.

Comparison of European Clinical Guidelines on the Management of Alcohol Use Disorders.

Background: Alcohol is a leading cause of morbidity and mortality in the European region, and tackling the harmful use of alcohol is a public health priority. Most countries in the region have national strategies for treating alcohol use disorders (AUD), but there is significant between-country variation.

Objectives: This study aimed to compare clinical guidelines for the management of AUD from countries of the European region and to determine whether countries' relative wealth or quality of their health systems had affected the guidelines.

Phosphatidylethanol Reliably and Objectively Quantifies Alcohol Consumption in Adolescents and Young Adults.

Background: Alcohol contributes to numerous annual deaths and various societal problems not just in adult, but also in adolescent, populations. Therefore, it is vital to find methods for reliably detecting alcohol use for early preventative measures. Research has shown phosphatidylethanol (PEth) to be superior to self-report instruments and indirect biomarkers for alcohol consumption in adult populations.

Phosphatidylethanol for Monitoring Alcohol Use in Liver Transplant Candidates: An Observational Study.

Liver transplantation remains an essential procedure for many patients suffering from alcoholic liver disease. Alcohol use monitoring remains paramount all through the stages of this complex process. Direct alcohol biomarkers, with improved specificity and sensibility, should replace traditional indirect markers.

Deficient Decision Making in Pathological Gamblers Correlates With Gray Matter Volume in Medial Orbitofrontal Cortex.

Individuals suffering from pathological gambling (PG) show impaired decision making, but it is still not clear how this impairment is related to other traits and neuroanatomical characteristics. In this study, we investigated how the influence of PG on decision making (1) is connected to different impulsivity facets and (2) how it is related to gray matter volume (GMV) in various brain regions. Twenty-eight diagnosed PG patients and 23 healthy controls completed the cups task to measure decision making.

Acute alcohol effects on impulsive choice in adolescents.

Background: Neurodevelopmental and alcohol-induced changes in decision-making have been proposed to critically influence impulsive behaviour in adolescents.

Objective: This study tested the influence of acute alcohol administration on impulsive choice in adolescents.

Methods: Fifty-four males aged 18-19 years were tested in a single-blind placebo-controlled cross-over design.

Dysfunctional approach behavior triggered by alcohol-unrelated Pavlovian cues predicts long-term relapse in alcohol dependence.

We demonstrated that alcohol-dependent patients who relapsed within 1 year after detoxification showed stronger PIT effects compared with abstainers and controls. Relapsers particularly failed to correctly perform in trials where an instrumental stimulus required inhibition while a Pavlovian background cue indicated a monetary gain. Under that condition, relapsers approached the instrumental stimulus, independent of the expected punishment.

A Survey on the Medical Use of Cannabis in Europe: A Position Paper.

Aim: This study was aimed at investigating the availability and prescription of different medicinal variants of cannabis and their status in European countries.

Methods: A -web-based survey was sent to all member societies of the -European Federation of Addiction Societies (EUFAS) in 2 waves during the summer of 2017. All 34 member societies in 19 different European countries were invited to participate.

Comparative Analysis of Potential Risk Factors for at-Risk Gambling, Problem Gambling and Gambling Disorder among Current Gamblers-Results of the Austrian Representative Survey 2015.

The risk of developing a problem gambling behavior is distributed unequally among the population. For example, individuals who report stressful life events, show impairments of mental health or belong to a socio-economically deprived group are affected more frequently by gambling problems. The aim of our study is to investigate whether these risk factors are equally relevant for all gambling groups (social = 0 DSM-5 criteria, at risk = 1 DSM-5 criterion, problem = 2-3 DSM-5 criteria, disordered = 4-9 DSM-5 criteria).

Screening for Hazardous Drinking in Nursing Home Residents: Evaluating the Validity of the Current Cutoffs of the Alcohol Use Disorder Identification Test-Consumption Questions by Using Ethyl Glucuronide in Hair.

Background: Because of physiological changes, elderly people are much more exposed to the adverse effects of alcohol. Therefore, hazardous drinking is defined at lower levels as compared to younger adults. This work aimed to evaluate the validity of the current cutoff levels of the Alcohol Use Disorder Identification Test-Consumption (AUDIT-C) questions to detect hazardous drinking in the elderly by using ethyl glucuronide in hair (HEtG).

Assessing phosphatidylethanol (PEth) levels reflecting different drinking habits in comparison to the alcohol use disorders identification test - C (AUDIT-C).

In addition to monitoring problematic or harmful alcohol consumption, drinking experiments indicated the potential of phosphatidylethanols (PEth) in abstinence monitoring. To date, no profound evaluation of thresholds for the differentiation of abstinence from moderate drinking and for detection of excessive consumption based on PEth homologues exists. Investigations with a large group of healthy volunteers (n=300) were performed to establish PEth reference values reflecting different drinking habits.

Marketing Status and Perceived Efficacy of Drugs for Supporting Abstinence and Reducing Alcohol Intake in Alcohol Use Disorders: A Survey among European Federation of Addiction Societies in Europe.

Background: Acamprosate, disulfiram (DIS), naltrexone and nalmefene can be used in treating alcohol use disorders. The drugs are, however, underutilized.

Methods: In this survey of marketing status and perceived efficacy, member societies of the European federation for addiction societies were asked to report on the status of these drugs in their country.

Genome-wide association study of pathological gambling.

Background: Pathological gambling is a behavioural addiction with negative economic, social, and psychological consequences. Identification of contributing genes and pathways may improve understanding of aetiology and facilitate therapy and prevention. Here, we report the first genome-wide association study of pathological gambling.
