Preclinical
Female C57BL/6J Mice Show Alcohol-Seeking Behaviour after Withdrawal from Prolonged Alcohol Consumption in the Social Environment
Short Summary: We developed a model to study alcohol drinking behaviour in an enriched and social environment. Long-term conditioning coupling with alcohol reward results in cue-induced alcohol-seeking behaviour in group-housed female C57BL/6J mice. Moreover, a high number of nosepokes on the last day of alcohol drinking conditioning might potentiate alcohol-seeking after withdrawal response.
Rat Model of Late Gestational Alcohol Exposure Produces Similar Life-Long Changes in Thalamic Nucleus Reuniens Following Moderate- Versus High-Dose Insult
Short Summary: We administered high- or moderate-dose alcohol to rats at a neurodevelopmental stage analogue of human third trimester. When these animals were examined in adulthood, we observed significant damage to thalamic nucleus reuniens (reductions in neuron and non-neuronal cell number, regional volume loss) at equal magnitude between doses (uncorrelated with peak blood alcohol concentration).
Biomedical
Investigation of Association of Rare, Functional Genetic Variants With Heavy Drinking and Problem Drinking in Exome Sequenced UK Biobank Participants
Short Summary: Tests for association of rare, functional genetic variants with heavy drinking and problem drinking confirm the known effects of variants in ADH1B and ALDH2 but fail to implicate novel variants or genes. Results for three genes potentially related to autism suggest that they might exert a protective effect.
MRI Analysis Of the Water Content Change In the Brain During Acute Ethanol Consumption Via Quantitative Water Mapping
Short Summary: We applied a precise quantitative MRI water mapping sequence in a prospective study in 20 healthy, alcohol-intoxicated volunteers. No significant water content or volume change in the brain, after recent alcohol intake, was found in the whole brain, grey and white matter, occipital and frontal lobes, thalamus and pons.
Irregular Autonomic Modulation Predicts Risky Drinking and Altered Ventromedial Prefrontal Cortex Response to Stress in Alcohol Use Disorder
Short Summary: Greater disruption in the autonomic nervous system was found in patients with alcohol use disorder, including higher overall approximate entropy (ApEn) and heart rate, compared to controls. Higher ApEn was associated with increased drinking and decreased stress response in brain regions of emotion regulation, such as the right ventromedial prefrontal cortex.
Cerebral Blood Flow in the Salience Network of Individuals with Alcohol Use Disorder
Short Summary: Non-treatment seeking alcohol use disorder participants show cerebral blood flow (CBF) deficits in the insular cortex compared with social drinkers. In addition, CBF in nodes of the salience network inversely correlates with degree of alcohol risk behaviors.
Behavioural
Unique and Transdiagnostic Dimensions of Reward Functioning in Attention-Deficit/Hyperactivity Disorder and Alcohol Use Disorder Symptoms
Short Summary: Findings highlight aspects of reward-related functioning in ADHD and AUD. Environmental suppressors were correlated with the ADHD-AUD dimension; proportionate substance-related reinforcement was uniquely correlated with AUD; and reward probability was uniquely associated with ADHD. Neither delay discounting nor hedonic capacity was a significant correlate of ADHD or AUD symptoms.
Levels of Parental Drinking in the Presence of Children: An Exploration of Attitudinal Correlates
Short Summary: This study examined perceived social norms and alcohol use in front of children among Australian adults. Many parents are consuming alcohol in front of their children, particularly fathers. Moderate parental drinking in front of children was considered acceptable but drunkenness was not.
The Role of Parental Control and Support in Declining Adolescent Drinking: A Multi-Level Study Across 30 European Countries
Short Summary: Across 30 European countries, parental control and parental support were associated with reduced adolescent drinking at the individual level, but not at the population level. It is unlikely that changes in parental control or support have contributed to the widespread cross-national declines in adolescent drinking observed in most high-income countries.
Changes in Hospital Discharges with Alcohol-Related Liver Disease in a Gastroenterology and General Medical Unit Following the Introduction of Minimum Unit Pricing of Alcohol: The GRI Q4 Study
Short Summary: We saw a reduction in the absolute number of ArLD hospital discharges as well as the number of individual patients involved since the introduction of MUP. However, the pattern of clinical presentation, disease severity, readmission rates and 90-day mortality was largely unaffected post-MUP in patients with ArLD.
Epidemiology and Policy
Exposure to Parental Alcohol Use Is Associated with Adolescent Drinking Even When Accounting for Alcohol Exposure of Best Friend and Peers
Short Summary: This longitudinal study followed 765 adolescents from the Netherlands for 3 years. Results indicated that throughout early adolescence, parental alcohol exposure was associated with offspring alcohol use, independently of whether peers or their best friend exposed them to alcohol or not.
Expected Years Of Life Lost Due To Alcohol Consumption In Thai Adults: A 16-Year Follow-Up Cohort Of National Health Examination Survey 2004–2019
Short Summary: Alcohol-related mortality and potential years of life lost in Thailand were substantial, with highest alcohol-attributable deaths from unspecified liver diseases, intentional self-harm injuries, cardiac arrhythmia and ischemic heart diseases. Our findings have considerable implications for reinforcing public health policies aiming to reduce alcohol consumption and its adverse consequences.
Predicting the Impact of Alcohol Taxation Increases on Mortality—A Comparison of Different Estimation Techniques
Short Summary: Four different analytic approaches were used to estimate the impact of a recent alcohol excise tax increase in Lithuania on all-cause mortality. While all resulted in decreases of mortality, the true effect was best estimated via a comparison between predictions derived from time-series methodology compared with actual number of deaths. The indirect analytic approaches based on alcohol-attributable fraction methodology seem to underestimate the true effect.
Social Threat Reduces Alcohol Consumption among College Students
Short Summary: College students who experienced social threat consumed significantly less alcohol than those who were socially accepted. This effect of social threat on alcohol consumption persisted when controlling for students’ typical alcohol consumption behavior.
The Impact of Increasing the Minimum Legal Drinking Age from 18 to 20 Years in Lithuania on All-Cause Mortality in Young Adults—An Interrupted Time-Series Analysis
Short Summary: We investigated the effect of an increase in minimum legal drinking age (MLDA) on all-cause mortality in young adults (aged 18–19). MLDA had a negative effect on all-cause mortality (even when controlling for general trends using other age groups), however when confounding factors were included, these effects were attenuated.
