Topiramate has been found to be effective in reducing alcohol use and may also attenuate anxiety severity in patients with alcohol use disorder (AUD). This study compared the neural response of treatment-seeking patients with AUD on either topiramate or naltrexone during an anticipatory anxiety task. Participants were 42 patients with AUD who were randomized to receive either topiramate (n = 23; titrated dose up to 200 mg/day) or naltrexone (n = 19; 50 mg/day) for 12-weeks as part of a larger randomized controlled trial. Following 6 weeks of treatment, participants completed an anticipatory anxiety task during a functional magnetic resonance imaging (fMRI) session. The task presented a series of high-threat and low-threat stimuli followed by an unpleasant or pleasant image, respectively. Primary whole-brain analyses revealed no significant differences in neural activation between the topiramate and naltrexone groups. Deactivation for safe cues relative to threat cues was observed within the precuneus, inferior parietal lobule and the cingulate gyrus. In the precentral and middle frontal gyri, threat cues elicited greater activation. Exploratory analyses revealed an effect of change in anxiety from baseline to week 6, with a greater reduction associated with a reduced response to threat cues relative to safe cues in the cuneus and lingual gyrus. The current study is the first to examine and compare neural activation during anticipatory anxiety in treatment-seeking individuals on topiramate and naltrexone. This preliminary research contributes to our understanding of the therapeutic mechanisms of these alcohol pharmacotherapies.

Purpose: Stressful life events are associated with problematic drinking, and alcohol misuse has been exacerbated during the coronavirus disease 2019 (COVID-19) pandemic. While coping motives may account for this association, positive life events (PLEs) and enhancement motives are understudied. To address these gaps, we examined the associations of history of alcohol use disorder (AUD), negative life events (NLEs), and PLEs with problematic alcohol use and tested coping and enhancement motives as mediators.

Methods: The sample included baseline and follow-up data from 241 participants enrolled in the National Institute on Alcohol Abuse and Alcoholism COVID-19 Pandemic Impact on Alcohol Study. Endorsements of past year PLEs and NLEs and their associations with problematic alcohol use were examined. Among the 202 current drinkers, path analyses tested mediational pathways via coping and enhancement motives.

Results: The top two PLEs were change in work conditions (21.6%) and taking a vacation (20.3%). The top two NLEs were change in social activities (36.5%) and major change in recreation (26.6%). Individuals with a history of AUD and those who experienced more NLEs reported higher coping and enhancement motives, which were associated with higher problematic alcohol use. Individuals who experienced more PLEs reported lower coping motives, which was associated with lower problematic alcohol use.

Conclusions: Besides coping motives, enhancement motives were also associated with pandemic problematic alcohol use. Alcohol interventions targeting reward- and relief-driven drinking patterns may be beneficial to individuals with a history of AUD and those who experienced more NLEs. More research is needed to study PLEs which may help inform the development of strength-based alcohol interventions.

Aims: Androgenetic alopecia (AGA) is widely recognized as the most common form of hair loss and can significantly affect individuals' quality of life. The association between alcohol consumption and AGA remains uncertain and controversial. Our primary objective is to investigate the relationship between alcohol consumption and AGA.

Methods: We identified studies from multiple databases, including Embase, MEDLINE, ScienceDirect, Scopus, and Web of Science, up to March 2024. For alcohol consumption, we included studies where it was defined as a categorical variable, such as Yes/No or classified by grams. For AGA, only cases that were clinically diagnosed were included. Odds ratios (ORs) and their corresponding 95% confidence intervals were extracted from the included studies. Subgroup analyses were conducted, considering factors such as gender and study design.

Results: Our findings indicated that individuals who consume alcohol had an OR of AGA compared to those who do not drink alcohol (OR, 1.40; 95% CI: .95-2.06; k = 6; I2 = 77%). In the subgroup analysis focusing on men, an OR for alopecia was observed (OR, 1.31; 95% CI: .85-2.01; k = 4; I2 = 78%). Additionally, a subgroup analysis based on study design revealed ORs of 1.93 (95% CI: 1.32-2.82; k = 3; I2 = 47%) for cross-sectional studies, and 1.69 (95% CI: 1.33-2.14; k = 2; I2 = 0%) for case-control studies.

Conclusions: Our results suggest that the effect of alcohol consumption on AGA may be less than initially assumed. Future research will require large, carefully planned cohort studies that incorporate standardized diagnostic criteria to provide more definitive insights.

Aim: The current study aims to (i) examine differences in hazardous alcohol consumption across different industries in Sweden and (ii) assess to what degree any such difference can be attributed to a differential distribution of nicotine use, health, and work environments among individuals working in these industries.

Methods: A pooled cross-sectional study was conducted including all participants of the survey of Health, Work Environment, and Lifestyle Habits between 2012 and 2023 (n = 54 378), collected by an occupational health service company (Feelgood). The survey contained self-reported information on alcohol use, industry, nicotine use, health, and work environment. Crude and adjusted odds ratios with 95% confidence intervals were obtained by pooled logistic regression analyses.

Results: Hazardous alcohol use was highly prevalent in the current study population (37%), especially among individuals in the accommodation/food service, arts/entertainment/recreation, and the construction industry. Compared to individuals working in education, individuals in these industries had >1.6-fold increased odds of reporting hazardous alcohol consumption. Differences in nicotine use and physical work environment between the industries explained some of the differences in hazardous alcohol consumption between industries, while differences in health and psychosocial work environment had limited effects on the estimates.

Conclusion: We identified several industries in the Swedish workforce where hazardous alcohol use is highly prevalent. While differences in nicotine use, health, and work environment explained a part of these risk differences, most of the risk differences remained.

Aims: This study described the burden of alcohol-related morbidity and mortality among those who had been enrolled in residential treatment for drug use disorders in Denmark and investigated whether self-reported information on alcohol use provided at treatment admission can be used to assess risk for future serious alcohol-related harms.

Methods: At baseline (entry in drug use disorder treatment during 2000-10), clients completed a European adaptation of the Addiction Severity Index-5. We tracked 4981 clients through 2018 using multiple national registers to identify fully (100%) alcohol-attributable hospital contacts and deaths.

Results: The death rate due to fully alcohol-attributable causes was 411 per 100 000 person-years, with an average of 0.18 fully alcohol-attributable hospital contacts per person-year. Using the Addiction Severity Index-5 alcohol composite score as a predictor in an adjusted competing risks regression model, a higher score was associated with a higher risk of alcohol-related death. The alcohol composite score was a significant predictor of alcohol-related hospital contacts in an adjusted recurrent events model.

Conclusions: A substantial proportion of people originally identified as experiencing drug use disorders have alcohol problems that need to be monitored and managed to prevent serious complications. By demonstrating the predictive power of self-reported data, our study concludes that the Addiction Severity Index-5 can be used to identify individuals with drug use disorders at risk for severe long-term alcohol-related health outcomes.

Background: Process mining was widely used in healthcare settings to analyse patient pathways, providing insights about patient care and resource allocation. This study aimed to apply process mining to explore service utilization and pathways of patients with alcohol use disorders in receiving the community-based Drug and Alcohol Service to establish a baseline for evaluating improvement initiatives.

Methods: Patients' encounters with the Drug and Alcohol Service and their direct care activities (i.e. Intake, Assessment, and treatment service activities) that occurred in these encounters were analysed to depict the actual pathways. Patterns were uncovered from these actual pathways using a process mining tool Disco. Patients with alcohol use disorders were divided into two groups-patients who use polysubstance and those who do not-to compare their service utilization and pathway patterns.

Results: Five hundred seventy-one patients with alcohol use disorders incurred 1447 encounters, comprising 13,974 activities. The top three actual pathways with at least three activities were: (i) pathway 'Intake-> Withdrawal Management-> Withdrawal Management' (170 (11.7%) encounters and 130 (22.8%) patients); (ii) pathway 'Intake-> Adult Counselling-> Adult Counselling' (161 (11.1%) encounters and 126 (22.1%) patients); and (iii) pathway 'Intake-> Assessment-> Withdrawal Management' (155 (10.7%) encounters and 129 (22.6%) patients). However, 313 (21.6%) encounters did not proceed beyond the Intake stage. When the patients started their pathways from Intake, their immediate next activities were frequently Withdrawal Management, Assessment or Adult Counselling. Compared to those who do not use polysubstance, patients who use polysubstance had a higher proportion of Intake (19.3% vs 11.8%, P < .001), Involuntary Treatment (4.0% vs 1.0%, P < .001) and Magistrate Early Referral into Treatment (6.4% vs .3%, P < .001), but a lower proportion of Withdrawal Management (31.2% vs 39.0%, P < .001) and Adult Counselling (27.8% vs 37.6%, P < .001).

Conclusion: This study contributes to an in-depth understanding of service utilization and pathways of patients with alcohol use disorders within the community-based Drug and Alcohol Service. Future studies should investigate their reasons for dropping out after Intake.

Aims: Excessive alcohol consumption is a major global health concern, contributing to millions of deaths annually and a significant proportion of cirrhosis cases; however, standardized protocols for early identification of alcohol-associated liver disease are lacking. In this retrospective cohort study, we aimed to understand the prevalence and risk factors associated with elevated liver stiffness measurement (LSM) in high-risk patients with alcohol use disorder (AUD) and identify variables associated with longitudinal abstinence and outcomes.

Methods: Veterans with severe AUD without known liver disease admitted to a 35-day residential substance use treatment program were offered liver health screening, including Fibroscan evaluation. Assessment of AUD severity and liver health outcomes were evaluated longitudinally by chart review.

Results and conclusions: In a cohort of 257 veterans with severe AUD admitted to residential treatment, 185 underwent Fibroscan evaluation, and 22 were identified to have elevated LSM concerning for compensated advanced chronic liver disease. Patients with elevated LSM were more likely to remain abstinent after 1 year. About 41% of patients with LSM ≥ 10 kPa (5% of all screened patients) were confirmed to have cirrhosis on follow-up and incorporated into routine hepatology care. Screening of liver disease in high-risk populations with non-invasive imaging modalities provides an opportunity to identify patients at risk for compensated advanced chronic liver disease before decompensation. Identification of increased risk for advanced chronic liver disease may promote abstinence in patients with severe AUD. Collaboration between mental health professionals and hepatologists is critical for the integration of care for patients with AUD and liver disease.

Aims: This study examined differential changes in alcohol use during the COVID-19 pandemic among adults with unhealthy alcohol use.

Methods: Among 62 924 adults identified with unhealthy alcohol use in primary care prepandemic (1 January 2019 to 29 February 2020), changes in alcohol use during the pandemic (1 March 2020 to 30 June 2022) were examined using electronic health record data from Kaiser Permanente Northern California. Outcomes were changes in heavy drinking days in the past three months (HDDs) and overall consumption (drinks/week), including continuous and categorical measures. Differences in outcomes by sex, age, race/ethnicity, and alcohol use disorder (AUD) were examined.

Results: On average, drinking was reduced by 3.0 HDDs (in the past three months) (SD = 18.4) and 4.1 drinks/week (SD = 12.2), but women, certain age groups, White patients, and patients without AUD had smaller decreases than their counterparts. Overall, 9.1% increased, 34.4% maintained, and 56.5% decreased HDDs, and 20.2% increased, 19.8% maintained, and 60.1% decreased drinks/week. Women, patients aged ≥35 years, White patients, and patients with AUD had higher odds of increasing versus decreasing HDDs, and maintaining versus decreasing, compared to their counterparts. Patients aged 18-20 years, White patients, and patients without AUD had higher odds than their counterparts of increasing versus decreasing drinks/week. Women, patients aged 18-20 years, Asian/Pacific Islander, and Latino/Hispanic patients had higher odds of maintaining versus decreasing drinks/week.

Conclusions: While alcohol use decreased overall among this sample of primary care patients with unhealthy drinking prepandemic, certain subgroups were more likely to increase drinking, suggesting a greater risk of alcohol-related problems.

Background: Phosphatidylethanol (PEth) is a specific marker of alcohol intake, used both as a screening method for hazardous use and as an outcome measure in the treatment of alcohol use disorder (AUD). However, what cut-off values to apply for hazardous use in a treatment setting is still unclear. We aimed to investigate the correlation between PEth and self-reported drinking and identify the optimal cut-off for hazardous use, for patients with AUD and a stated goal of controlled drinking.

Methods: We used data from a randomized controlled trial of two different psychological treatments aiming for controlled drinking, conducted within specialized addiction care in Stockholm, Sweden. A total of 181 patients left samples that could be included in the current analysis. Outcomes were measured at five different time points over 2 years of follow-up. PEth 16:0/18:1 values were correlated with subjective reports of recent drinking based on the Timeline Follow-Back Method.

Results: The correlation between PEth and self-reported alcohol intake increased significantly over time, with the weakest correlation found at baseline (Spearman's ρ = 0.42) and the strongest at the 104-week follow-up (ρ = 0.69). When used to indicate hazardous drinking according to Swedish guidelines (≥10 units per week), receiver operating characteristic analysis revealed PEth ≥ 0.22 μmol/l to be the optimal cut-off.

Conclusions: PEth is a useful outcome measure that can be used to validate subjective reports of current drinking. In a treatment setting aimed at controlled drinking, the accuracy of patients' self-report measures seems to improve over time. In this context, a PEth value of ≥0.22 μmol/l is a sensitive and specific indicator of hazardous drinking.
