Background: Movement restrictions during the coronavirus disease 2019 (COVID-19) pandemic have inflicted stress and affected drinking behavior. However, limited information is available on the changes in alcohol use among the Japanese population.Method: This retrospective study included 371 subjects aged 20–74 years who underwent medical checkups at Fuyoukai Murakami Hospital before (April 1, 2019 to December 31, 2019) and during the COVID-19 pandemic (April 1, 2020 to May 31, 2020). All data were extracted from medical records. Changes in alcohol consumption and severity were also investigated. A logistic regression model was used to identify the risk factors associated with increased drinking, and seven variables were sequentially introduced into the model—age (≤ 49 years), male sex, prior instructions for alcohol restriction, medication for lifestyle-related diseases (e.g., hypertension, dyslipidemia, type 2 diabetes mellitus, and hyperuricemia), depression or insomnia, essential workers, and smoking.Results: The median age was 46 years, and 81.7% subjects were men. In total, 25.1% subjects increased their alcohol intake, and 24.5% subjects reduced their alcohol intake. The rates of excessive alcohol consumption (≥ 60 g ethanol per day) were 15.9% and 16.7% in the pre-COVID-19 period and during the COVID-19 pandemic, respectively. Multivariate analysis identified only age ≤ 49 years as a risk factor for increased drinking (adjusted odds ratio, 2.20; 95% confidence interval, 1.22–3.99; p = 0.009).Conclusion: Approximately one-fourth of the subjects reported increased drinking, although the overall severity remained stable. The importance of alcohol reduction, particularly among young people, should be emphasized.

Abstract The aim of this study was to examine the diagnostic usefulness of carbohydrate-deficient transferrin (CDT) in serum in a cross-sectional study of 439 treated hypertensive men. We related the results to alcohol intake by questionnaire and to biochemical and hemodynamic measurements known to reflect excessive alcohol consumption. The diagnostic sensitivity and the specificity for high alcohol intake (> or = 24 g/day of ethanol) were 44% and 87%, respectively. The group with reported high alcohol intake (n = 32) was characterized by hemodynamic and biochemical changes typical of alcohol abuse. The corresponding profile for the patients with increased serum CDT concentrations (n = 70) was different in several respects, indicating a considerable number of false-positive tests. We conclude that serum CDT determination had low sensitivity and specificity for excessive alcohol consumption in this group of hypertensive patients. The results illustrate the importance of evaluating new laboratory methods in unselected patient populations before drawing any conclusions about their clinical value.

Abstract Objective: Excessive alcohol consumption during reproductive years may impact the integrity of developing eggs and sperm, potentially affecting the life-long health of future children. Inadequate diets could aggravate these preconception effects of alcohol. The aim of the present study was to assess the prevalence of excessive alcohol consumption and explore whether weekly alcohol intake is associated with energy and nutrient intake and adequacy of micronutrient intake among students. Design: Cross-sectional survey using a validated and reproducibility-tested FFQ. Setting: University of Agder, Norway, in 2018. Participants: 622 students (71 % female). Results: More than 80 % reported having consumed alcoholic beverages the past 4 weeks. One-third of men and 13 % of women exceeded the upper recommended limit of 14 UK alcohol units/week. An inverse association between increasing alcohol intake and energy-adjusted micronutrient intake was evident for thiamine, phosphate, Fe, Zn and Se in men, and for vitamin A, β-carotene, vitamin E and C, thiamine, vitamin B6, folate, P, Mg, K, Fe, Zn and Cu in women. A substantial proportion had vitamin D, folate, Fe and I intakes below average requirement regardless of alcohol consumption level. The combination of prevalent alcohol use, decreasing micronutrient density of diet across alcohol consumption level and a high probability of micronutrient inadequacy indicate reason for concern in a preconception public health perspective. Conclusions: Our findings call for investigations into young adults’ knowledge, reflections and beliefs regarding diet and alcohol use to understand how these behaviours could be improved ahead of parenthood.

AbstractMany genes differentially expressed in brain tissue from human alcoholics and animals that have consumed large amounts of alcohol are components of the innate immune toll-like receptor (TLR) pathway. TLRs initiate inflammatory responses via two branches: (1) MyD88-dependent or (2) TRIF-dependent. All TLRs signal through MyD88 except TLR3. Prior work demonstrated a direct role for MyD88-dependent signaling in regulation of alcohol consumption. However, the role of TLR3 as a potential regulator of excessive alcohol drinking has not previously been investigated. To test the possibility TLR3 activation regulates alcohol consumption, we injected mice with the TLR3 agonist polyinosinic:polycytidylic acid (poly(I:C)) and tested alcohol consumption in an every-other-day two-bottle choice test. Poly(I:C) produced a persistent increase in alcohol intake that developed over several days. Repeated poly(I:C) and ethanol exposure altered innate immune transcript abundance; increased levels of TRIF-dependent pathway components correlated with increased alcohol consumption. Administration of poly(I:C) before exposure to alcohol did not alter alcohol intake, suggesting that poly(I:C) and ethanol must be present together to change drinking behavior. To determine which branch of TLR signaling mediates poly(I:C)-induced changes in drinking behavior, we tested either mice lacking MyD88 or mice administered a TLR3/dsRNA complex inhibitor. MyD88 null mutants showed poly(I:C)-induced increases in alcohol intake. In contrast, mice pretreated with a TLR3/dsRNA complex inhibitor reduced their alcohol intake, suggesting poly(I:C)-induced escalations in alcohol intake function are, at least partially, dependent on TLR3. Together, these results strongly suggest that TLR3-dependent signaling drives excessive alcohol drinking behavior.HighlightsActivation of TLR3 via poly(I:C) increased alcohol intake.Poly(I:C) and ethanol must be present together to change drinking behavior.Increased alcohol intake due to poly(I:C) is independent of MYD88.Increased alcohol intake due to poly(I:C) is dependent on TLR3.

Dorsomedial Striatum

ABSTRACTFyn kinase in the dorsomedial striatum (DMS) of rodents plays a central role in mechanisms underlying excessive alcohol intake. The DMS is comprised of medium spiny neurons (MSNs) that project directly (dMSNs) or indirectly (iMSNs) to the substantia nigra. Here, we examined the cell-type specificity of Fyn’s actions on alcohol use. First, we knocked down Fyn selectively in DMS dMSNs or iMSNs of mice and measured the level of alcohol consumption. We found that downregulation of Fyn in dMSNs, but not in iMSNs, reduces excessive alcohol but not saccharin intake. D1Rs are coupled to Gαs/olf, which activate cAMP signaling. To examine whether Fyn’s actions are mediated through cAMP signaling, DMS dMSNs were infected with GαsDREADD, and the activation of Fyn signaling was measured following CNO treatment. We found that remote stimulation of cAMP signaling in DMS dMSNs activates Fyn and promotes the phosphorylation of the Fyn substrate, GluN2B. In contract, remote activation of GαsDREADD in DLS dMSNs did not alter Fyn signaling. We then tested whether activation of GαsDREADD in DMS dMSNs or iMSNs alters alcohol intake and observed that CNO-dependent activation of GαsDREADD in DMS dMSNs but not iMSNs increases alcohol but not saccharin intake. Finally, we examined the contribution of Fyn to GαsDREADD-dependent increase in alcohol intake, and found that systemic administration of the Fyn inhibitor, AZD0503 blocks GαsDREADD-dependent increase in alcohol consumption. Our results suggest that the cAMP-Fyn axis in the DMS dMSNs is a molecular transducer of mechanisms underlying the development of excessive alcohol consumption.

AbstractLarge conductance potassium (BK) channels are among the most sensitive molecular targets of ethanol. Whether the action of ethanol at BK channels influences the motivation to drink alcohol remains to be determined. In the present study, we sought to investigate the behavioral relevance of this interaction by introducing in the mouse genome a point mutation (BK α K361N) known to render BK channels insensitive to ethanol while preserving their physiological function. We demonstrate that preventing ethanol’s interaction with BK channels at this site hinders the escalation of voluntary alcohol intake induced by repeated cycles of alcohol intoxication and withdrawal. In contrast, the mutation does not alter ethanol’s acute behavioral effects, nor the metabolic and activity changes induced by chronic exposure to alcohol. Our findings point at BK channel ethanol-sensing capacity as a vulnerability mechanism in the transition from moderate alcohol consumption to pathological patterns of alcohol abuse.

: Background: This study aimed to compare the diagnostic performance of carbohydrate-deficient transferrin (CDT) and gamma-glutamyltranspeptidase (γ-GTP) to assess the single and combined benefits of these biological markers for the detection of chronic excessive alcohol consumption in patients with alcoholic cirrhosis. Methods: Biological markers were determined in blood samples from patients with alcoholic cirrhosis (drinking group, n = 35; nondrinking group, n = 81). The prediction accuracy of %CDT alone, γ-GTP alone, and their combination for the detection of excessive alcohol consumption was determined in patients with alcoholic cirrhosis. Results: Serum total bilirubin, alanine aminotransferase, aspartate aminotransferase, γ-GTP, and alkaline phosphatase levels and %CDT were significantly higher and serum albumin levels were significantly lower in the drinking group than in the nondrinking group. The combination of %CDT and γ-GTP compared with %CDT or γ-GTP alone showed a higher prediction accuracy. The combination of %CDT and γ-GTP exhibited a higher specificity than γ-GTP alone. However, in terms of sensitivity, no significant difference was found between single or combined markers. Conclusions: The combination of %CDT and γ-GTP is considered a useful biomarker of chronic excessive alcohol consumption in patients with alcoholic cirrhosis.
