Negative reinforcement is proposed to mediate associations between sleep and alcohol use, especially among people with depression and/or anxiety symptoms. Worse sleep (e.g., shorter duration, less efficiency, more irregular timing) exacerbates negative emotions, which alcohol may temporarily relieve. Not yet examined, we propose sleep indirectly impacts early stages of alcohol use via differences in negative reinforcement learning (NRL), since sleep impacts emotion, reward response, and learning. The current study aimed to replicate associations between sleep and alcohol use, test associations with NRL, and examine indirect associations between sleep health and alcohol use via NRL among 60 underage college students (ages 18-20 years, 77% female) varying in depression and anxiety symptoms. Participants wore Fitbit smartwatches and completed daily diaries measuring sleep and substance use for ∼14 days before completing two computer tasks assessing social (SNRL) and monetary (MNRL) negative reinforcement learning. Robust generalized linear models tested direct associations within the proposed model. SNRL performance was positively associated with alcohol use, but no other associations were observed. Statistical mediation models failed to indicate indirect effects of sleep on alcohol use via SNRL or MNRL performance. Post-hoc exploratory models examining depression and anxiety symptoms as moderators of direct associations indicated several interactions. Positive associations between sleep timing variability and alcohol use were weakened at higher anxiety symptom severity and stronger at higher depression symptom severity. The positive association between SNRL performance and alcohol use was also stronger at higher depression symptom severity. Among students with elevated depression symptoms, variable sleep timing and stronger SNRL performance were independently associated with more alcohol use, but indirect effects were not supported. Future research should replicate findings, confirm causality of interactions, and examine sleep timing and behavioral responses to negative social stimuli as targets for improving alcohol-related outcomes among underage college students with elevated depressive symptoms.

Substance use continues to be recognized as one of the major health and social issues in the Caribbean. This study focusses on the risks and consequences of adolescent school student's exposure to alcohol and prevention strategies. Participants were selected from the age group of 13 to 19 years old, who are attending Secondary School. Five schools were chosen according to the prevalence of alcohol. Students were purposively selected from each school based on the recommendations from the school social workers. Students completed the Adolescent Drug Involvement Scale (ADIS) to understand the extent of involvement in alcohol use. The study recommends that there is a need for effective parenting where training in awareness, skills, and techniques around engaging young adolescent students with age-appropriate information on alcohol abuse can be disbursed and reinforced as they enter various stages of their development.

In rodent models of fetal alcohol spectrum disorders (FASD), cognitive deficits are implicated in impaired T-maze spatial reversal learning. Rat studies have indicated supplemental administration of choline during the developmental period of alcohol exposure can ameliorate spatial reversal deficits. This study tested whether beneficial effects of prenatal choline supplementation could be confirmed in a sheep model of binge exposure in the first trimester equivalent. Two hypotheses were tested: 1) alcohol exposure would produce deficits in reversal of a T-maze position discrimination; and 2) gestational dietary supplementation of choline would ameliorate those deficits. Mated ewes were assigned to one of seven groups-a normal control (NC) group or one of six infusion treatment groups: saline control (SC; isotonic saline), saline control plus choline (SC-CH; isotonic saline plus choline, 10 mg/kg administered orally throughout each day of gestation), binge alcohol (BA; 1.75 g/kg alcohol per infusion day), binge alcohol plus choline (BA-CH; 1.75 g/kg/day alcohol plus choline), heavy binge alcohol (HBA; 2.5 g/kg/day alcohol), or heavy binge alcohol plus choline (HBA-CH; 2.5 g/kg/day alcohol plus choline). The alcohol infusions modeled a weekend binge drinking pattern over the first trimester-equivalent (gestational day 4-41). T-maze training began at 12 weeks of age, with daily sessions occurring 5 days/week. Lambs were given five days of habituation training, followed by five days of position discrimination training (3 trials per daily session, intertrial interval of 3 hours, reinforced side randomly assigned across subjects). Lambs were then given 10 days of training on the reversal task. There was no difference among groups during acquisition. Alcohol impaired reversal learning, and choline supplementation mitigated these deficits in the HBA-CH group. These results suggest that maternal dietary choline supplementation can ameliorate or prevent some impairments of executive function in a sheep model of FASD.

Introduction: The impact of the COVID-19 pandemic on hospitalizations for alcohol-associated hepatitis (AH) is poorly understood. Here we explore AH trends from 2016-2020 and evaluate demographic disparities including sex and race.

Methods: A retrospective analysis of the 2016-2020 Healthcare Cost and Utilization Project National Inpatient Sample was performed to assess temporal trends in hospitalizations for AH. The 2020 dataset was evaluated to compare AH hospitalizations between those with and without an additional diagnosis of COVID-19.

Results: Included were 607,140 weighted inpatient AH discharges per 145,055,152 all-cause discharges from 2016-2020. AH hospitalizations increased at a rate of 23.4 hospitalizations per 100,000 all-cause discharges per year between 2016-2019 and increased to 113 hospitalizations per 100,000 all-cause discharges in 2020. Mortality was higher in females despite lower rates of hospitalization than males. The adjusted odds of hospitalization for AH in 2020 were higher than in 2016-2019 (aOR= 1.28, p < 0.001). The Hispanic population had greater odds of hospitalization with AH and COVID-19 compared to other races (aOR= 2.71, p <0.001).

Discussion: Increased efforts toward primary prevention of excessive alcohol use and greater social support for those with alcohol used disorder are needed. More research is required to elucidate the racial disparities among the Hispanic population with AH and COVID-19.

Harmful use of alcohol effects the health of the population. The treatment coverage of alcohol use disorders (AUD) varies among countries. The study aimed to determine the inclusion of AUD medicines in various national Essential Medicine Lists (EMLs) and its association with alcohol consumption. It was a secondary data analysis of alcohol consumptions and AUD related medicines in EML. Data were extracted from the WHO Global Essential Medicines database and the WHO Global Status Report on Alcohol and Health 2018. Data were extracted for 194 countries. Only 132 of 194 countries (68.0%) had EML, and among the 132 countries only 27.3% had included AUD medicines in their EML. Only 36 countries had included any of the AUD medicines in their EML. Disulfiram was included by 23 countries, while Acamprosate and Naltrexone was included by only four and 19 countries, respectively. Among the countries, 36.1% were from upper-middle income countries and 16.65 from low-income countries. The inclusion of AUD medicines in national EML was neither associated with alcohol consumption parameters nor the alcohol consumption related policy parameters. Considering the high prevalence of AUD and its complications, there is an urgent need to focus on including AUD medicines in national EML for making AUD treatment available and accessible across the world.

Fetal Alcohol Spectrum Disorders (FASD) are one of the most common causes of mental disability in the world. Despite efforts to increase public awareness of the risks of drinking during pregnancy, epidemiological studies indicate a prevalence of 1-6% in all births. There is growing evidence that deficits in sensory processing may contribute to social problems observed in FASD. Multisensory (MS) integration occurs when a combination of inputs from two sensory modalities leads to enhancement or suppression of neuronal firing. MS enhancement is usually linked to processes that facilitate cognition and reaction time, whereas MS suppression has been linked to filtering unwanted sensory information. The rostral portion of the posterior parietal cortex (PPr) of the ferret is an area that shows robust visual-tactile integration and displays both MS enhancement and suppression. Recently, our lab demonstrated that ferrets exposed to alcohol during the "third trimester equivalent" of human gestation show less MS enhancement and more MS suppression in PPr than controls. Here we complement these findings by comparing in vivo electrophysiological recordings from channels located in shallow and deep cortical layers. We observed that while the effects of alcohol (less MS enhancement and more MS suppression) were found in all layers, the magnitude of these effects were more pronounced in putative layers V-VI. These findings extend our knowledge on the sensory deficits of FASD.

Problem drinking affects not only the health of a population but also the productivity of a nation, especially if it is rampant among the working population. This study examines the association between problem drinking and work characteristics, work-family status, and social situations among the Japanese working population. Multivariable logistic regression analysis was performed on the basis of gender on 3136 participants (men: 65.1%, women: 34.9%) adopted from the Japanese Civil Servants Study in 2014 (response rate: 87.8%), to examine the factors related to problem drinking, after adjusting for frequency and quantity of drinking. Problem drinking was assessed using the Cutdown, Annoyed, Guilty, and Eye-opener (CAGE) questionnaire. The presence of problem drinking was found in 24.3% of men and 10.3% of women. The analysis showed that in men, poor work performance (OR: 1.34, 95% CI: 1.00-1.79), high family-to-work conflict (OR: 1.54, 95% CI: 1.14-2.09), and high work-to-family conflict (OR: 1.63, 95% CI: 1.14-2.34) were significantly associated with problem drinking, whereas in women, high work-to-family conflict (OR: 2.45, 95% CI: 1.21-4.95) was significantly associated with problem drinking. Although the number of close friends is negatively associated with problem drinking in women, the significance disappeared in the fully adjusted model. It can be concluded that it is important for both men and women to strike a balance between work and family life. Moreover, owing to gender differences, work performance may be important for men, and the presence of close friends may be important for women, in reducing the risk of problem drinking.

Background: MicroRNAs are abundant in serum and have emerged as important regulators of gene expression, implicating them in a wide range of diseases. The purpose of this study was to discover and validate serum miRNAs in prediabetes associated with alcohol dependence syndrome (ADS).

Method: Serum samples from ADS patients with or without prediabetes and normoglycemic controls were subjected to microarray. Validation of identified candidate miRNAs was performed by RT-qPCR. Additionally, GO and KEGG pathway analyses were carried out to uncover target genes anticipated to be controlled by the candidate miRNAs.

Results: Notably, 198, and 172 miRNAs were differentially expressed in ADS-patients with or without prediabetes compared to healthy controls, and 7 miRNAs in ADS-patients with prediabetes compared to ADS-normoglycemic patients, respectively. Furthermore, hsa-miR-320b and hsa-miR-3135b were differentially expressed exclusively in ADS-patients with prediabetes, and this was further validated. Interestingly, GO and KEGG pathway analysis revealed that genes predicted to be modulated by the candidates were considerably enriched in numerous diabetes-related biological processes and pathways.

Conclusion: Our findings revealed that ADS-patients with or without prediabetes have different sets of miRNAs compared to normoglycemic healthy subjects. We propose serum hsa-miR-320b and hsa-miR-3135b as potential biomarkers for the diagnosis of prediabetes in ADS-patients.
