Brain-derived neurotrophic factor Val66Met polymorphism moderates the relationship between impulsivity, negative emotions, and binge drinking intensity in university students.

Studies on the genetic factors involved in binge drinking (BD) and its associated traits are very rare. The aim of this cross-sectional study was to investigate differences in the association between impulsivity, emotion regulation and BD in a sample of young adults according to the rs6265/Val66Met variant in the brain-derived neurotrophic factor (BDNF) gene, a well-known candidate gene in alcohol use disorders. We recruited 226 university students (112 women), aged between 18 and 25 years old, from two centers in France.

Ethanol (EtOH)-Related Behaviors in α-Synuclein Mutant Mice and Association of SNCA SNPs with Anxiety in EtOH-Dependent Patients.

Background: Data have shown a role of α-synuclein in anxiety and also in addiction, particularly in alcohol use disorders (AUD). Since the comorbidity between AUD and anxiety is very high and because anxiety is an important factor in ethanol (EtOH) relapse, the aim of the present study was to investigate the role of α-synuclein in moderating EtOH intake, the anxiolytic effects of EtOH, and EtOH withdrawal-induced anxiety and convulsions in mice. The study aimed to determine whether SNCA variants moderated anxiety in EtOH-dependent patients.

[Severe acute alcoholic hepatitis].

All chronic and excessive consumer of alcohol with recent jaundice should be assessed using a Maddrey's score for severe acute alcoholic hepatitis. Corticosteroids are the first line of treatment, associated with an appropriate nutritional support and alcohol abstinence. Corticosteroids plus N-acetylcysteine combination improves short-term survival over corticosteroids alone, and could be proposed as a first line therapy.
