Prevention, screening, and treatment for heavy drinking and alcohol use disorder

Uncovering the impact of alcohol on internal organs and reproductive health: Exploring TLR4/NF-kB and CYP2E1/ROS/Nrf2 pathways

This review delves into the detrimental impact of alcohol consumption on internal organs and reproductive health, elucidating the underlying mechanisms involving the Toll-like receptor 4 (TLR4)/Nuclear factor kappa light chain enhancer of activated B cells (NF-kB) pathway and the Cytochrome P450 2E1 (CYP2E1)/reactive oxygen species (ROS)/nuclear factor erythroid 2-related factor 2 (Nrf2) pathways. The TLR4/NF-kB pathway, crucial for inflammatory and immune responses, triggers the production of pro-inflammatory agents and type-1 interferon, disrupting the balance between inflammatory and antioxidant responses when tissues are chronically exposed to alcohol. Alcohol-induced dysbiosis in gut microbes heightens gut wall permeability to pathogen-associated molecular patterns (PAMPs), leading to liver cell infection and subsequent inflammation. Concurrently, CYP2E1-mediated alcohol metabolism generates ROS, causing oxidative stress and damaging cells, lipids, proteins, and deoxyribonucleic acid (DNA). To counteract this inflammatory imbalance, Nrf2 regulates gene expression, inhibiting inflammatory progression and promoting antioxidant responses. Excessive alcohol intake results in elevated liver enzymes (ADH, CYP2E1, and catalase), ROS, NADH, acetaldehyde, and acetate, leading to damage in vital organs such as the heart, brain, and lungs. Moreover, alcohol negatively affects reproductive health by inhibiting the hypothalamic-pituitary-gonadal axis, causing infertility in both men and women. These findings underscore the profound health concerns associated with alcohol-induced damage, emphasizing the need for public awareness regarding the intricate interplay between immune responses and the multi-organ impacts of alcohol consumption.

An assessment of beliefs about mental health care among community-based adults with severe, untreated alcohol use disorder

OBJECTIVE

Alcohol use disorder (AUD) is among the most prevalent substance use disorders in the USA. Despite availability of effective interventions, treatment initiation and engagement remain low. Existing interventions target motivation and practical barriers to accessing treatment among individuals established within treatment systems. In contrast, Cognitive Behavioral Therapy for Treatment-Seeking (CBT-TS) aims to elicit and modify treatment-seeking beliefs to increase treatment-seeking behaviors among treatment-naïve samples. We aim to understand which beliefs were endorsed by those who did/did not initiate treatment, including changes in number of drinking days.

METHOD

We examined treatment seeking beliefs elicited during CBT-TS among community-based adults with moderate-severe AUD with no treatment history. In this study, we discuss which beliefs were modifiable (i.e. those discussed during the intervention among individuals who subsequently attended treatment and may be associated with treatment-seeking behaviors).

RESULTS

Of the 194 participants who received the intervention, 16 categories of beliefs were endorsed. Of the 38 participants (19.6%) who attended treatment, the most frequently endorsed belief was 'Not wanting specific types of substance use treatment or supports' (50%), a belief that may inhibit treatment seeking. The idea 'Treatment is positive' (47%) was also frequently cited, a belief that may facilitate treatment seeking.

CONCLUSIONS

This study describes the beliefs that were more frequently endorsed among adults with moderate-severe, but untreated AUD who reported attending treatment following CBT-TS. Findings point to the potential of discussing and modifying treatment-seeking beliefs among treatment-naïve adults with severe AUD to increase treatment-seeking behaviors.

A physiologically-based digital twin for alcohol consumption-predicting real-life drinking responses and long-term plasma PEth

Alcohol consumption is associated with a wide variety of preventable health complications and is a major risk factor for all-cause mortality in the age group 15-47 years. To reduce dangerous drinking behavior, eHealth applications have shown promise. A particularly interesting potential lies in the combination of eHealth apps with mathematical models. However, existing mathematical models do not consider real-life situations, such as combined intake of meals and beverages, and do not connect drinking to clinical markers, such as phosphatidylethanol (PEth). Herein, we present such a model which can simulate real-life situations and connect drinking to long-term markers. The new model can accurately describe both estimation data according to a χ2 -test (187.0 < Tχ2 = 226.4) and independent validation data (70.8 < Tχ2 = 93.5). The model can also be personalized using anthropometric data from a specific individual and can thus be used as a physiologically-based digital twin. This twin is also able to connect short-term consumption of alcohol to the long-term dynamics of PEth levels in the blood, a clinical biomarker of alcohol consumption. Here we illustrate how connecting short-term consumption to long-term markers allows for a new way to determine patient alcohol consumption from measured PEth levels. An additional use case of the twin could include the combined evaluation of patient-reported AUDIT forms and measured PEth levels. Finally, we integrated the new model into an eHealth application, which could help guide individual users or clinicians to help reduce dangerous drinking.

Associations Between a Primary Care-Delivered Alcohol-Related Brief Intervention and Subsequent Opioid-Related Outcomes

OBJECTIVE

The co-occurrence of unhealthy alcohol use and opioid misuse is high and associated with increased rates of overdose, emergency health care utilization, and death. The current study examined whether receipt of an alcohol-related brief intervention is associated with reduced risk of negative downstream opioid-related outcomes.

METHODS

This retrospective cohort study included all VISN-6 Veterans Affairs (VA) patients with Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) screening results (N=492,748) from 2014 to 2019. Logistic regression was used to examine the association between documentation of an alcohol-related brief intervention and probability of a new 1) opioid prescription, 2) opioid use disorder (OUD) diagnosis, or 3) opioid-related hospitalization in the following year, controlling for demographic and clinical covariates.

RESULTS

Of the veterans, 13% (N=63,804) had "positive" AUDIT-C screen results. Of those, 72% (N=46,216) had a documented alcohol-related brief intervention. Within 1 year, 8.5% (N=5,430) had a new opioid prescription, 1.1% (N=698) had a new OUD diagnosis, and 0.8% (N=499) had a new opioid-related hospitalization. In adjusted models, veterans with positive AUDIT-C screen results who did not receive an alcohol-related brief intervention had higher odds of new opioid prescriptions (adjusted odds ratio [OR]=1.10, 95% CI=1.03-1.17) and new OUD diagnoses (adjusted OR=1.19, 95% CI=1.02-1.40), while new opioid-related hospitalizations (adjusted OR=1.19, 95% CI=0.99-1.44) were higher although not statistically significant. Removal of medications for OUD (MOUD) did not impact associations. All outcomes were significantly associated with an alcohol-related brief intervention in unadjusted models.

CONCLUSIONS

The VA's standard alcohol-related brief intervention is associated with subsequent lower odds of a new opioid prescription or a new OUD diagnosis. Results suggest a reduction in a cascade of new opioid-related outcomes from prescriptions through hospitalizations.

Psychosocial and medication interventions to stop or reduce alcohol consumption during pregnancy

BACKGROUND

Despite the known harms, alcohol consumption is common in pregnancy. Rates vary between countries, and are estimated to be 10% globally, with up to 25% in Europe.

OBJECTIVES

To assess the efficacy of psychosocial interventions and medications to reduce or stop alcohol consumption during pregnancy.

SEARCH METHODS

We searched the Cochrane Drugs and Alcohol Group Specialised Register (via CRSLive), Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, CINAHL, Web of Science, and PsycINFO, from inception to 8 January 2024. We also searched for ongoing and unpublished studies via ClinicalTrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP). All searches included non-English language literature. We handsearched references of topic-related systematic reviews and included studies.

SELECTION CRITERIA

We included randomised controlled trials that compared medications or psychosocial interventions, or both, to placebo, no intervention, usual care, or other medications or psychosocial interventions used to reduce or stop alcohol use during pregnancy. Our primary outcomes of interest were abstinence from alcohol, reduction in alcohol consumption, retention in treatment, and women with any adverse event.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methodological procedures.

MAIN RESULTS

We included eight studies (1369 participants) in which pregnant women received an intervention to stop or reduce alcohol use during pregnancy. In one study, almost half of participants had a current diagnosis of alcohol use disorder (AUD); in another study, 40% of participants had a lifetime diagnosis of AUD. Six studies took place in the USA, one in Spain, and one in the Netherlands. All included studies evaluated the efficacy of psychosocial interventions; we did not find any study that evaluated the efficacy of medications for the treatment of AUD during pregnancy. Psychosocial interventions were mainly brief interventions ranging from a single session of 10 to 60 minutes to five sessions of 10 minutes each. Pregnant women received the psychosocial intervention approximately at the end of the first trimester of pregnancy, and the outcome of alcohol use was reassessed 8 to 24 weeks after the psychosocial intervention. Women in the control group received treatment as usual (TAU) or similar treatments such as comprehensive assessment of alcohol use and advice to stop drinking during pregnancy. Globally, we found that, compared to TAU, psychosocial interventions may increase the rate of continuously abstinent participants (risk ratio (RR) 1.34, 95% confidence interval (CI) 1.14 to 1.57; I2 =0%; 3 studies; 378 women; low certainty evidence). Psychosocial interventions may have little to no effect on the number of drinks per day, but the evidence is very uncertain (mean difference -0.42, 95% CI -1.13 to 0.28; I2 = 86%; 2 studies; 157 women; very low certainty evidence). Psychosocial interventions probably have little to no effect on the number of women who completed treatment (RR 0.98, 95% CI 0.94 to 1.02; I2 = 0%; 7 studies; 1283 women; moderate certainty evidence). None of the included studies assessed adverse events of treatments. We downgraded the certainty of the evidence due to risk of bias and imprecision of the estimates.

AUTHORS' CONCLUSIONS

Brief psychosocial interventions may increase the rate of continuous abstinence among pregnant women who report alcohol use during pregnancy. Further studies should be conducted to investigate the efficacy and safety of psychosocial interventions and other treatments (e.g. medications) for women with AUD. These studies should provide detailed information on alcohol use before and during pregnancy using consistent measures such as the number of drinks per drinking day. When heterogeneous populations are recruited, more detailed information on alcohol use during pregnancy should be provided to allow future systematic reviews to be conducted. Other important information that would enhance the usefulness of these studies would be the presence of other comorbid conditions such as anxiety, mood disorders, and the use of other psychoactive substances.

Evolutionary perspectives on substance and behavioural addictions: Distinct and shared pathways to understanding, prediction and prevention

Addiction poses significant social, health, and criminal issues. Its moderate heritability and early-life impact, affecting reproductive success, poses an evolutionary paradox: why are humans predisposed to addictive behaviours? This paper reviews biological and psychological mechanisms of substance and behavioural addictions, exploring evolutionary explanations for the origin and function of relevant systems. Ancestrally, addiction-related systems promoted fitness through reward-seeking, and possibly self-medication. Today, psychoactive substances disrupt these systems, leading individuals to neglect essential life goals for immediate satisfaction. Behavioural addictions (e.g. video games, social media) often emulate ancestrally beneficial behaviours, making them appealing yet often irrelevant to contemporary success. Evolutionary insights have implications for how addiction is criminalised and stigmatised, propose novel avenues for interventions, anticipate new sources of addiction from emerging technologies such as AI. The emerging potential of glucagon-like peptide 1 (GLP-1) agonists targeting obesity suggest the satiation system may be a natural counter to overactivation of the reward system.

Does the decline in Swedish adolescent drinking persist into early adulthood?

BACKGROUND AND AIMS

Sweden has experienced a substantial decrease in adolescent drinking over the past decades. Whether the reduction persists into early adulthood remains unclear. Using survey data, the present study aimed to determine whether reductions in indicators of alcohol use observed among adolescents remain in early adulthood and whether changes in alcohol intake are consistent among light/moderate and heavy drinkers.

DESIGN

Data from the Swedish monthly Alcohol Monitoring Survey (2001-20) were used to construct five 5-year birth cohorts (1978-82, 1983-87, 1988-92, 1993-97 and 1998-2002).

SETTING

Sweden.

PARTICIPANTS

A total of n = 52 847 respondents (48% females) aged 16 and 30 years were included in this study.

MEASUREMENTS

For both males and females, temporal changes in the prevalence of any drinking, the prevalence of heavy episodic drinking (HED) and total alcohol intake in the past 30 days in centilitres were analysed.

FINDINGS

The prevalence of any drinking in more recent cohorts remained low until young people came into their early (females) and mid- (males) 20s. Male cohorts differed in the prevalence of HED across age, with the later cohorts showing lower odds than earlier cohorts (odds ratios between 0.54 and 0.66). Among females, no systematic differences between cohorts across age could be observed. Later male birth cohorts in light/moderate drinkers had lower alcohol intake than earlier cohorts (correlation coefficients between -0.09 and -0.54). No statistically significant cohort effects were found for male heavy drinkers. Although differences in alcohol intake among females diminished as age increased, the cohorts did not differ systematically in their level of alcohol intake.

CONCLUSIONS

In Sweden, the reduced uptake of drinking in adolescents appears to fade as people move into adulthood. Observed reductions in alcohol intake among light and moderate drinkers appear to persist into adulthood. More recent male cohorts show a lower prevalence rate of heavy episodic drinking.

Satisfaction with a digital support tool targeting alcohol consumption: perspectives from participants in a randomized control trial

AIM

Intervention design may be improved through evaluating the feedback from those who have been exposed to such interventions. As such, here the perspectives of the intervention group from a recent randomized control trial investigating the effectiveness of a digital alcohol intervention, in terms of perceived suitability and usefulness of the support tool they engaged with, were investigated.

METHODS

Respondents (N=475; 45% of the intervention group) answered five quantitative questions addressing user experience, completed the 10-item System Useability Scale, and were offered the opportunity to write free-text feedback. Quantitative measures were analysed using ordinal and linear regression with baseline characteristics as predictors, and free-text responses were evaluated using content analysis.

RESULTS

Overall, respondents were positive towards the intervention in terms of it fitting their needs, the usefulness of the tools included, and the usefulness of text message content. The intervention was perceived as more helpful by respondents with lower total weekly alcohol consumption, higher self-reported confidence in their ability to reduce their drinking, and the perceived importance there of, at baseline. The free-text comments revealed the value of reminders as prompts to reflect on one's own drinking behaviour. Nonetheless, criticisms of the intervention were voiced, primarily highlighting the repetitive nature of the reminders and the lack of individuation in advice. Some also feltlike the intervention was impersonal and targeted only a specific drinking pattern.

CONCLUSIONS

Experiences of the intervention group in this trial were generally positive, though there may be demand for more individualised, targeted intervention design.

How Modifiable Are Modifiable Dementia Risk Factors? A Framework for Considering the Modifiability of Dementia Risk Factors

Many risk factors for dementia, identified from observational studies, are potentially modifiable. This raises the possibility that targeting key modifiable dementia risk factors may reduce the prevalence of dementia, which has led to the development of dementia risk reduction and prevention strategies, such as intervention trials or dementia prevention guidelines. However, what has rarely been considered in the studies that inform these strategies is the extent to which modifiable dementia risk factors can (1) be identified by individuals, and (2) be readily modified by individuals. Characteristics of modifiable dementia risk factors such as readiness of identification and targeting, as well as when they should be targeted, can influence the design, or success of strategies for reducing dementia risk. This review aims to develop a framework for classifying the degree of modifiability of dementia risk factors for research studies. The extent to which these modifiable dementia risk factors could be modified by an individual seeking to reduce their dementia risk is determined, as well as the resources that might be needed for both risk factor identification and modification, and whether modification may be optimal in early-life (aged <45 years), midlife (aged 45-65 years) or late-life (aged >65 years). Finally, barriers that could influence the ability of an individual to engage in risk factor modification and, ultimately, dementia risk reduction are discussed.

Patient Perspectives on Pharmacotherapy of Alcohol Dependence

INTRODUCTION

Pharmacotherapy with drugs like naltrexone or acamprosate is a well-evaluated element in the treatment of alcohol dependence (AD). However, in many countries, these medications are rarely administered. The objective of the present study was to identify from patients' perspective factors that prevent the initiation and compliance with pharmacological treatment of AD.

METHODS

Patients from inpatient alcohol withdrawal treatment underwent a standardized interview. Questions included socio-demographic data, history of AD, treatment history, knowledge and personal experience regarding pharmacotherapy of AD, and personal views about the causes of AD.

RESULTS

Three hundred patients (mean age 47.3 years, 27.7% female, mean duration of AD 8.9 years, 67% with a history of previous inpatient withdrawal treatment) were included. The majority of patients (58.7%) already knew drugs for the pharmacotherapy of AD. Thirty percent had ever used such medications, most often acamprosate. Except for disulfiram, pharmacotherapy of AD had lasted only a few weeks, on average. Medication usually had been applied without additional psychotherapy. No severe side effects were reported. Patients had often stopped pharmacotherapy on their own, when assuming they had reached stable abstinence. Openness to start pharmacotherapy for AD was currently stated by 67% of the total sample. In multiple logistic regression, openness was predicted by having a concept of AD as a medical disease and by a shorter duration of AD.

DISCUSSION

To improve the administration of pharmacotherapy for AD implementation strategies should be systematically developed and evaluated with a focus on the concept of AD as a medical disease.

Alcohol Treatment Access and Engagement Among Women in the USA: a Targeted Review of the Literature 2012-2022

Purpose of Review

The purpose of this review is to examine recent literature (2012-2022) on alcohol treatment access and engagement in women in the U.S. and propose future directions for research and clinical practice.

Recent Findings

A targeted literature review resulted in 27 studies encompassing screening and brief intervention (SBIRT), treatment utilization, treatment engagement, and barriers to treatment. Recent literature demonstrates overall low rates of screening and brief interventions and treatment utilization in the population with women less likely to be screened and utilize alcohol treatment. The magnitude of these gender differences varies with race/ethnicity. Extensive barriers to care include provider knowledge, structural barriers, and attitudinal barriers and these vary with service setting, gender, and race/ethnicity.

Summary

There is an increasing prevalence of alcohol use and Alcohol Use Disorder (AUD) in women with low rates of screening, brief treatment, treatment, and engagement which have resulted from extensive barriers to care. Possible areas of further inquiry include the impact of race/ethnicity on gender differences, improving provider and system level policies to promote SBIRT and treatment engagement and utilization, further developing digital interventions, and implementation research to investigate factors associated with optimizing effectiveness of gender-responsive and culturally tailored interventions that address the unique needs of women.

Brief, cognitive-behavioral intervention to promote treatment seeking in adults with severe alcohol use disorder: A randomized controlled trial

BACKGROUND AND AIMS

There is little RCT evidence that brief interventions improve treatment seeking in individuals with severe alcohol use disorder (AUD) or treatment seeking reduces alcohol use. The aim was to test the efficacy of a brief intervention to increase treatment seeking in treatment naïve adults with severe AUD and measure its effects on alcohol use.

DESIGN

Parallel group, non-pharmacologic RCT with intervention (n = 197) and active control (n = 203) conditions, with blinded assessors conducting follow-ups at 1, 3 and 6 months.

SETTING

Online recruitment in a 17-county region of upstate New York, USA.

PARTICIPANTS

Inclusion criteria consisted of ages ≥18 years, Alcohol Use Disorders Identification Test score ≥16, exceeds recommended limits for alcohol use and no history of AUD treatment. n = 400; 50% female; 79% white; mean age, 40.7; mean education, 14.6 years.

INTERVENTION AND COMPARATOR

One-session telephone-delivered interventions: Cognitive-Behavioral Therapy for Treatment Seeking (CBT-TS; intervention), review of a National Institute on Alcohol Abuse and Alcoholism pamphlet on AUD treatment (control).

MEASUREMENTS

Self-report of any AUD treatment use over 3 months (primary outcome) and two standard measures of alcohol use over 6 months (secondary outcomes).

FINDINGS

Intent-to-treat analyses were used. Assessment follow-up rates were ≥93%. Any alcohol-related treatment use over 3-month follow-up was obtained by 38 (19%) intervention participants and 36 (18%) control participants, a non-significant difference, χ2 [1] = 0.16, P = 0.689. Secondary analysis showed a significant interaction term between sex and intervention assignment (β = -1.197, P = 0.027). The interaction suggested CBT-TS was effective in men (22% vs 13%), although the evidence was somewhat weak (P = 0.071), and it was not effective in women (17% vs 24%).

CONCLUSIONS

A one-session cognitive-behavioral therapy intervention to increase treatment seeking in treatment naïve adults with severe alcohol use disorder did not increase treatment seeking.

HIV Prevention and Care Among Black Cisgender Sexual Minority Men and Transgender Women: Protocol for an HIV Status-Neutral Cohort Study Using an Observational-Implementation Hybrid Approach

BACKGROUND

Black cisgender gay, bisexual, and other sexual minority men (SMM) and transgender women (TW) continue to be heavily affected by HIV. Further research is needed to better understand HIV prevention and care outcomes in this population. In particular, there is a need for research examining the impact of substance use and sleep health on HIV prevention and treatment outcomes among Black SMM and TW.

OBJECTIVE

This paper outlines the study methods being used in the recently launched follow-up study to the Neighborhoods and Networks (N2) study, which we refer to as N2 Part 2 (N2P2). N2P2 aims to address this gap in the literature, build off the findings of the original N2 study, and identify socioenvironmental determinants of health, including whether neighborhood and network factors mediate and moderate these relationships.

METHODS

Building on the N2 cohort study in Chicago from 2018 to 2022, N2P2 used a prospective longitudinal cohort design and an observational-implementation hybrid approach. With sustained high levels of community engagement, we aim to recruit a new sample of 600 Black SMM and TW participants residing in the Chicago metropolitan statistical area. Participants are asked to participate in 3 study visits across an 18-month study period (1 visit every 9 months). Four different forms of data are collected per wave: (1) an in-person survey, (2) biological specimen collection, (3) a daily remote ecological momentary assessment for 14 days after each study visit, and (4) data from electronic health records. These forms of data collection continue to assess neighborhood and network factors and specifically explore substance use, sleep, immune function, obesity, and the implementation of potential interventions that address relevant constructs (eg, alcohol use and pre-exposure prophylaxis adherence).

RESULTS

The N2P2 study was funded in August 2021 by the National Institute of Drug Abuse (R01DA054553 and R21DA053156) and National Heart, Lung, and Blood Institute (R01HL160325). This study was launched in November 2022. Recruitment and enrollment for the first wave of data collection are currently ongoing.

CONCLUSIONS

The N2P2 study is applying innovative methods to comprehensively explore the impacts of substance use and sleep health on HIV-related outcomes among an HIV status-neutral cohort of Black SMM and TW in Chicago. This study is applying an observational-implementation hybrid design to help us achieve findings that support rapid translation, a critical priority among populations such as Black SMM and TW that experience long-standing inequities with regard to HIV and other health-related outcomes. N2P2 will directly build off the findings that have resulted from the original N2 study among Black SMM and TW in Chicago. These findings provide a better understanding of multilevel (eg, individual, network, and neighborhood) factors that contribute to HIV-related outcomes and viral suppression among Black SMM and TW.

Exploratory mixed methods analysis of self-authored content from participants in a digital alcohol intervention trial

BACKGROUND

Digital interventions readily permit data capture of participant engagement with them. If future interventions are intended to be more interactive, tailored, or a useful resource offered to users, it may be valuable to examine such data. One module available in a digital alcohol intervention recently tested in a randomised control trial offered participants the opportunity to self-author prompts that were sent to them by a text message at a time of their choosing. This study thus aimed to evaluate these self-authored prompts to increase knowledge on how individuals negotiate behaviour change and assess whether intervention content can be improved in the future.

METHODS

The self-authored prompts were evaluated qualitatively using a combination of content and thematic analysis. The identified themes and subcategories are exemplified using anonymized quotes, and the frequency that each identified theme was coded for among the prompts was calculated. Associations between baseline characteristics and the odds of authoring a prompt at all, as well as a prompt within each theme, were investigated using logistic regression.

RESULTS

Five themes were identified (Encouragement Style, Level of Awareness, Reminders of reasons to reduce/quit, Strategies to reduce/quit, and Timescale), all with several subcategories. The prompts module was more likely to be used by women and older individuals, as well as those for whom reducing alcohol consumption was perceived as important, or who felt they had the know-how to do so. Participants who had immediate access to the support tool (intervention group) were more than twice as likely to author a prompt (OR = 2.36; probability of association > 99%) compared to those with 4-month delayed access (control group).

CONCLUSIONS

Individuals who engaged with the prompts module showed evidence of using the information provided in the support tool in an active way, with several showing goal setting and making plans to change their drinking behaviour. Individuals also used this opportunity to remind themselves of personal and specific reasons they wanted to change their drinking, as well as to encourage themselves to do so.

Alcohol Withdrawal Presenting with Cut Throat Injury during COVID-19 Lockdown: Case Reports from Nepal

Background

The relationship between alcohol dependence and suicidal tendency is well recognized. Self-harm by cut throat is an uncommon but is potentially life-threatening when attempted. We present a description and discussion of a series of three cases of alcohol dependence syndrome who presented with self-inflicted cut throat wounds during the lockdown period from 24th March to 7th July 2020 due to the COVID-19 pandemic at the largest tertiary care hospital in Nepal. Case description. During the three and a half months of COVID-19 lockdown, we had three cases of alcohol dependence syndrome presenting to emergency services with a self-inflicted cut throat injury. Two cases were diagnosed as having alcohol withdrawal delirium and one case as alcohol-induced psychotic disorder (alcoholic hallucinosis) as per the international classification of mental and behavioral disorders diagnostic criteria for research. All three cases were alcohol dependent for more than a decade, but with no prior self-harm attempts. Necessary surgical interventions were done by the Department of Otorhinolaryngology, and in liaison with the Department of Psychiatry, appropriate psychiatric management was done. All three cases had uneventful outcomes in regard to wound care and mental disorder.

Conclusion

Suicidal precautions should be taken in alcohol dependence during phases of consumption and abstinence. Screening for alcohol dependence and withdrawal should be a standard process in all self-harm cases that present to the emergency department during a crisis.

Opioid agonist therapy and mortality among First Nations and other residents with concurrent alcohol use disorder in British Columbia, Canada: A population-based cohort study

BACKGROUND

Despite the prevalence of alcohol use among people with opioid use disorder (PWOUD) engaged in opioid agonist therapy (OAT), clinical care guidance for concurrent alcohol use disorder (AUD) and OUD is scarce. We assessed the prevalence and risk of mortality for concurrent AUD among PWOUD who accessed OAT in British Columbia (BC).

METHODS

Data were obtained from six linked population-level health administrative datasets to identify PWOUD from January 1996 to March 2020. All-cause age and sex standardized mortality ratios (SMR) were calculated to determine the mortality risk by OAT status (on vs. discontinued), stratified by First Nations and other residents with concurrent AUD and OUD. Adjusted risk ratios compared the relative risk of mortality by AUD status (AUD detected vs. not) among First Nations and other residents.

RESULTS

We identified 62,110 PWOUD who received OAT, including 6305 (10.2%) First Nations. OAT substantially lowered the SMR among First Nations (SMR=6.6, 95% CI: 5.4-8.1) and other residents (SMR=6.6; 95% CI: 6.2-7.0) with concurrent AUD and OUD, compared to those who discontinued (SMR=22.7, 95% CI: 20.4-25.1, SMR=17.5, 95% CI: 16.8-18.2 respectively). The risk of mortality was 1.9 (95% CI: 1.6-2.2) times higher for First Nations and 2.0 (95% CI: 1.8-2.2) times higher for other residents with concurrent OUD and AUD compared to those without an indication of AUD.

CONCLUSIONS

The protective effect of OAT remained despite the presence of a concurrent AUD among both First Nations and other residents with OUD. Findings have implications for clinical care management of concurrent disorders.

Short-term effect of household indebtedness and risk of alcohol use disorder among Korean youth: 2017-2020 longitudinal panel study

BACKGROUND

In Republic of Korea, household debt has increased recently among young adults, especially during the COVID-19 pandemic. Household debt may potentially lead to numerous outcomes including alcohol use disorder (AUD). The aim of this study was to investigate the relationship between a change in indebtedness and the risk of developing AUD.

METHODS

A total of 5,091 participants (2,720 men and 2,371 women) were included during a 4-year study period. Indebtedness was divided into four groups: no debt a year ago and at present (group 1), paying off a year's debt (group 2), newly incurred current debt after a year when there was no debt (group 3), and indebtedness a year ago and at present (group 4). Groups 2, 3, and 4 were also divided into subgroups based on debt characteristics. AUD risk was evaluated by the CAGE scale, and a score of 2 or higher was defined as AUD high risk. Several time-varying socioeconomic and health-related characteristics were adjusted.

RESULTS

Participants who indicated indebtedness at present (groups 3 and 4) were more likely to be AUD high-risk compared to group 1 in both genders (men: adjusted relative risk [aRR] = 1.031, 95% CI [1.014-1.049] in group 3, aRR = 1.028, 95% CI [1.007-1.050] in group 4; women: aRR = 1.039, 95% CI [1.016-1.163] in group 3, aRR = 1.028, 95% CI [1.007-1.050] in group 4). Even paid-off debt affected the risk of AUD among female participants (aRR = 1.018, 95% CI [1.001-1.034] in group 2). Women whose amount of debt increased for 1 year were more likely to be AUD high-risk compared to group 1. Women showed higher aRR than men for increasing CAGE scores by one unit in all debt subgroups.

CONCLUSION

Our research demonstrated a possible link between indebtedness and a heightened risk of AUD. These results underscore the importance of implementing targeted screening and interventions for AUD, particularly among young women who are facing mounting levels of debt.

Risks of alcohol and drug use disorders in prostate cancer survivors: a national cohort study

BACKGROUND

Prostate cancer (PC) survivors may potentially use substances to cope with psychological distress or poorly controlled physical symptoms. Little is known, however, about the long-term risks of alcohol use disorder (AUD) or drug use disorders in men with PC.

METHODS

A national cohort study was conducted in Sweden of 180 189 men diagnosed with PC between 1998 and 2017 and 1 801 890 age-matched population-based control men. AUD and drug use disorders were ascertained from nationwide records through 2018. Cox regression was used to compute hazard ratios (HRs) while adjusting for sociodemographic factors and prior psychiatric disorders. Subanalyses examined differences by PC treatment from 2005 to 2017.

RESULTS

Men with high-risk PC had increased risks of both AUD (adjusted HR = 1.44, 95% confidence interval [CI] = 1.33 to 1.57) and drug use disorders (adjusted HR = 1.93, 95% CI = 1.67 to 2.24). Their AUD risk was highest in the first year and was no longer significantly elevated 5 years after PC diagnosis, whereas their drug use disorders risk remained elevated 10 years after PC diagnosis (adjusted HR = 2.26, 95% CI = 1.45 to 3.52), particularly opioid use disorder (adjusted HR = 3.07, 95% CI = 1.61 to 5.84). Those treated only with androgen-deprivation therapy had the highest risks of AUD (adjusted HR = 1.91, 95% CI = 1.62 to 2.25) and drug use disorders (adjusted HR = 2.23, 95% CI = 1.70 to 2.92). Low- or intermediate-risk PC was associated with modestly increased risks of AUD (adjusted HR = 1.38, 95% CI = 1.30 to 1.46) and drug use disorders (adjusted HR = 1.19, 95% CI = 1.06 to 1.34).

CONCLUSIONS

In this large cohort, men with PC had significantly increased risks of both AUD and drug use disorders, especially those with high-risk PC and treated only with androgen-deprivation therapy. PC survivors need long-term psychosocial support and timely detection and treatment of AUD and drug use disorders.

Medications for treating alcohol use disorder: A narrative review

Chronic heavy alcohol use impacts all major neurotransmitter systems and is associated with multiple medical, psychiatric, and social problems. Available evidence-based medications to treat alcohol use disorder (AUD) are underutilized in clinical practice. These medications promote abstinence or reduce alcohol consumption, though there are questions regarding their optimal dosage, length of treatment, and utility in combination with one another. Pharmacogenetic approaches, which use a patient's genetic make-up to inform medication selection, have garnered great interest but have yet to yield results robust enough to incorporate them in routine clinical care. This narrative review summarizes the evidence both for medications approved by the Food and Drug Administration (disulfiram, oral naltrexone, acamprosate, and extended-release naltrexone) and those commonly used off-label (e.g., gabapentin, baclofen, and topiramate) for AUD treatment. We discuss these drugs' mechanisms of action, clinical use, pharmacogenetic findings, and treatment recommendations. We conclude that the most consistent evidence supporting the pharmacotherapy of AUD is for the opioid antagonists, naltrexone and nalmefene (which is not approved in the United States), and topiramate. These medications demonstrate consistent small or moderate effects in reducing the frequency of drinking and/or heavy drinking. Lastly, we make suggestions for research needed to refine and expand the current literature on effective pharmacotherapy for AUD.

Grounding alcohol simulation models in empirical and theoretical alcohol research: a model for a Northern Plains population in the United States

The growing number of systems science simulation models for alcohol use (AU) are often disconnected from AU models within empirical and theoretical alcohol research. As AU prevention/intervention efforts are typically grounded in alcohol research, this disconnect may reduce policy testing results, impact, and implementation. We developed a simulation model guided by AU research (accounting for the multiple AU stages defined by AU behavior and risk for harm and diverse transitions between stages). Simulated projections were compared to historical data to evaluate model accuracy and potential policy leverage points for prevention and intervention at risky drinking (RD) and alcohol use disorder (AUD) stages. Results indicated prevention provided the greatest RD and AUD reduction; however, focusing exclusively on AUD prevention may not be effective for long-term change, given the continued increase in RD. This study makes a case for the strength and importance of aligning subject-based research with systems science simulation models.

Standardized Models for Identification and Intervention for Emergency Department Patients at Risk for Alcohol Use Disorder

Alcohol use disorder (AUD) is chronic, lasting a person's lifetime. An increase in driving under the influence of alcohol, as well as emergency department (ED) visits, has been reported. The Alcohol Use Disorder Identification Test Consumption (AUDIT-C) is utilized to assess hazardous drinking. The Screening, Brief Intervention, Referral to Treatment (SBIRT) model assists in early intervention and referral for treatment. The Transtheoretical Model standardized instrument assesses individual readiness to change. These tools may be used by nurses and nonphysicians in the ED to help reduce alcohol use and the consequences of its use.

Age Specificity of Effects of Health Problems on Drinking Reduction: A Lifespan Developmental Analysis

Older adult drinking poses a growing public health concern, especially given the ongoing aging of the United States population. As part of a larger lifespan developmental project contrasting predictors of drinking reductions across different periods of adulthood, we tested age differences in effects of health problems on drinking declines across young adulthood, midlife, and older adulthood. We predicted these effects to be developmentally specific to midlife and older adulthood. We also tested moderation by alcohol use disorder (AUD) symptomatology and by indices of sociodemographic disadvantage (sex and race/ethnicity). Analyses used data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), leveraging NESARC's vast age range (18-90 + ; N = 43,093) and two waves of longitudinal data. Multiple-group cross-lag models tested differences across age groups in cross-lag paths between health problems and alcohol consumption. As hypothesized, health problem effects on drinking reductions were developmentally specific to midlife and older adulthood. However, models testing moderation by AUD symptomatology showed that these adaptive effects of health problems on drinking reductions did not extend to those with one or more AUD symptoms. Little evidence was found for moderation by sex or race/ethnicity. Findings support the notion of health concerns as a pathway to drinking reduction that increases in importance across the adult lifespan. However, given the moderation by AUD symptoms, findings also highlight a need to understand barriers to health-related pathways to drinking reduction among relatively severe midlife and older adult drinkers. These findings hold implications for lifespan developmental tailoring of clinical, public health, and policy interventions.

Blunted neural reward response to alcohol and greater alcohol motivation in binge drinkers in a randomized clinical experiment

BACKGROUND

Alcohol stimulates cerebral blood flow (CBF) in brain reward regions. However, neural processes that support sustained alcohol motivation after the first drink are not well understood.

METHODS

Using a novel placebo-controlled, randomized, crossover experiment, 27 individuals who binge drink (BD; 15 M, 12 F) and 25 social drinkers (SD; 15 M, 10 F) underwent a behavioral test of self-motivated alcohol consumption using an Alcohol Taste Test (ATT) involving alcoholic and nonalcoholic beer on separate days. The test was followed immediately by perfusion functional magnetic resonance imaging (fMRI). On both days, participants then engaged in a post-scan ATT with placebo beer to assess sustained alcohol self-motivation without active alcohol effects. Linear mixed effects models were used to examine the effects of drinking group on the placebo-controlled effect of initial alcohol motivation on brain perfusion (whole brain corrected p < 0.001, cluster corrected p < 0.025) and on the relationship between placebo-controlled brain perfusion and sustained alcohol motivation.

RESULTS

Initial alcohol self-motivation in the alcohol relative to placebo session led to markedly decreased activation in the medial orbitofrontal cortex (OFC) and the ventral striatum in BD relative to SD, indicative of neural reward tolerance. The BD group also showed an enhanced neural response in behavioral intention regions of the supplementary motor area (SMA) and inferior frontal gyrus (IFG) regions. Moreover, there was greater sustained alcohol motivation in BD than SD in the post-scan ATT in the alcohol relative to placebo session. Correspondingly, only in BD and only in the alcohol session, lower alcohol-induced OFC response correlated with concurrent sensitized SMA response, and each predicted the subsequent sustained higher alcohol motivation in the post-scan ATT.

CONCLUSIONS

Alcohol-related OFC tolerance may play an important role in sustained alcohol motivation. Furthermore, both specific alcohol-related neural reward tolerance and premotor sensitization responses may contribute to escalating alcohol motivation to drive excessive alcohol intake, even in individuals without alcohol use disorder.

The nomological network of drinker identity: A scoping review

BACKGROUND

Despite the growing interest in the construct of drinker identity and empirical evidence for its role in drinking behavior, there is a paucity of papers that evaluate and integrate the results of studies on drinker identity, leaving a gap in our knowledge of the importance of the drinker identity construct. The current paper addresses this gap by reviewing and integrating the results of the studies of drinker identity.

METHODS

The scoping review identified, retrieved, and evaluated the existing literature regarding drinker identity. English language studies from EBSCOHost, PubMed, ScienceDirect, and Scopus databases were reviewed. Studies were included in the review if they were data-based studies or theoretical publications with drinker identity as the primary topic published in peer-reviewed journals. Studies were reviewed and coded based on their reported methodology and findings and codes were used to integrate and present findings.

RESULTS

This review advances this line of research in four ways. First, the operationalization of drinker identity is evaluated by examining the theoretical frameworks defining the construct. Second, the conceptualization and measurement of drinker identity is assessed, with suggestions for future measurement research. Third, an integrated framework of predictors, outcomes, moderators, and mediators is presented. Finally, the research gaps, future recommendations, and clinical implications are discussed.

CONCLUSIONS

There is a need for continued research, specifically research which aims to standardize and improve measurement of drinker identity, considers longitudinal and developmental processes, and broadens the research samples and settings.

Telemedicine for unhealthy alcohol use in adults living with HIV in Alabama using common elements treatment approach: A hybrid clinical efficacy-implementation trial protocol

Background

Unhealthy alcohol use is an unaddressed barrier to achieving and maintaining control of the human immunodeficiency virus (HIV) epidemic. Integrated screening, treatment of common behavioral and mental health comorbidities, and telemedicine can improve alcohol treatment and HIV clinical and quality of life outcomes for rural and underserved populations.

Objective

In a randomized controlled clinical trial, we will evaluate the effectiveness and implementation of telephone-delivered Common Elements Treatment Approach (T-CETA), a transdiagnostic cognitive behavioral therapy protocol, on unhealthy alcohol use, HIV, other substance use and mental health outcomes among predominantly rural adults with HIV receiving care at community clinics in Alabama.

Methods

Adults with HIV receiving care at four selected community clinics in Alabama will receive a telephone-delivered alcohol brief intervention (BI), and then be assigned at random (stratified by clinic and sex) to no further intervention or T-CETA. Participants will be recruited after screening positively for unhealthy alcohol use or when referred by a provider. The target sample size is 308. The primary outcome will be change in the Alcohol Use Disorder Identification Test (AUDIT) at six- and 12-months post-enrollment. Additional outcomes include HIV (retention in care and viral suppression), patient-reported mental health (anxiety, depression, posttraumatic stress), and quality of life. A range of implementation measures be evaluated including T-CETA provider and client acceptability, feasibility, cost and cost-effectiveness.

Conclusions

This trial will inform alcohol treatment within HIV care programs, including the need to consider comorbidities, and the potential impact of alcohol interventions on HIV and quality of life outcomes.

Perceived barriers to seeking treatment for alcohol use disorders among the general Danish population - a cross sectional study on the role of severity of alcohol use and gender

BACKGROUND

A minority of all individuals with alcohol use disorders (AUD) seek treatment. Since the suffering from AUD has severe consequences for both the individual and for society, it is important to improve the understanding of barriers to seeking treatment. Most studies of barriers thus far have been conducted in the United States of America or the United Kingdom. There is a need for studies from other contexts. The overall aim is to investigate barriers to treatment seeking for AUD. The specific aims are to: 1) describe barriers to AUD treatment at different levels of alcohol use. 2) compare gender differences regarding barriers to AUD treatment.

METHODS

Study design: Cross-sectional.

PARTICIPANTS

1594 representative Danish adults from the general population aged 30-65 years. An online questionnaire was administrated by a market research company. The questionnaire covered demographic data, barriers to treatment and level of alcohol use. Analyses were performed by means of chi-2 test and logistic regression.

RESULTS

The most common barriers were related to stigma and shame: admitting to others of having a problem, being labelled, fear of the consequences and that others would find out. Participants with higher severity of alcohol use were more likely to endorse a wish to handle alcohol problems themselves and to report barriers related to treatment services. Women with high severity of alcohol use, endorsed higher level of fear of the consequences than men.

CONCLUSIONS

There is an urgent need to reduce stigma around AUD. Individuals with higher severity of alcohol use report a lower willingness to seek professional treatment if a problem occurs. Especially among individuals with high severity of alcohol use there is a need to address gender specific barriers.

Biomarkers of moderate alcohol intake and alcoholic beverages: a systematic literature review

The predominant source of alcohol in the diet is alcoholic beverages, including beer, wine, spirits and liquors, sweet wine, and ciders. Self-reported alcohol intakes are likely to be influenced by measurement error, thus affecting the accuracy and precision of currently established epidemiological associations between alcohol itself, alcoholic beverage consumption, and health or disease. Therefore, a more objective assessment of alcohol intake would be very valuable, which may be established through biomarkers of food intake (BFIs). Several direct and indirect alcohol intake biomarkers have been proposed in forensic and clinical contexts to assess recent or longer-term intakes. Protocols for performing systematic reviews in this field, as well as for assessing the validity of candidate BFIs, have been developed within the Food Biomarker Alliance (FoodBAll) project. The aim of this systematic review is to list and validate biomarkers of ethanol intake per se excluding markers of abuse, but including biomarkers related to common categories of alcoholic beverages. Validation of the proposed candidate biomarker(s) for alcohol itself and for each alcoholic beverage was done according to the published guideline for biomarker reviews. In conclusion, common biomarkers of alcohol intake, e.g., as ethyl glucuronide, ethyl sulfate, fatty acid ethyl esters, and phosphatidyl ethanol, show considerable inter-individual response, especially at low to moderate intakes, and need further development and improved validation, while BFIs for beer and wine are highly promising and may help in more accurate intake assessments for these specific beverages.

Alcohol use disorder in community management of chronic liver diseases

Rising rates of alcohol use disorder (AUD) combined with increases in alcohol-related liver disease (ALD) and other liver disease have resulted in the need to develop alcohol management strategies at all levels of patient care. For those with pre-existing liver disease, whether ALD or others, attention to alcohol use treatment and abstinence becomes critical to avoiding worsening liver-related consequences. Modalities to help patients reduce or stop alcohol include screening/brief intervention/referral to treatment, various therapeutic modalities including cognitive behavioral therapy, motivational enhancement therapy and 12-step facilitation, and alcohol relapse prevention medications. Harm reduction approaches versus total abstinence may be considered, but for those with existing ALD, particularly advanced ALD (cirrhosis or acute alcoholic hepatitis), total abstinence from alcohol is the recommendation, given clear data that ongoing alcohol use worsens mortality and liver-related morbidity. For certain populations, alcohol cessation is even more critically important. For those with hepatitis C or NAFLD, alcohol use accelerates negative liver-related outcomes. In women, alcohol use accelerates liver damage and results in worsened liver-related mortality. Efforts to integrate AUD and liver disease care are urgently needed and can occur at several levels, with establishment of multidisciplinary ALD clinics for fully integrated co-management as an important goal.

Interprofessional education as a potential foundation for future team-based prevention of alcohol use disorder

BACKGROUND

Effective screening of alcohol use and prevention of alcohol use disorder (AUD) requires the continuous preparation of educated and confident providers across all health professions who will ideally work in close collaboration in their future practices. As one mechanism for achieving this goal, the development and provision of interprofessional education (IPE) training modules for health care students may cultivate beneficial interactions among future health providers early in their formative education.

METHODS

In the present study, we assessed attitudes about alcohol and confidence in screening and AUD prevention in 459 students at our health sciences center. Students represented ten different health professions (audiology, cardiovascular sonography, dental hygiene, dentistry, medicine, nursing, physical therapy, public health, respiratory therapy, and speech language pathology programs). For purposes of this exercise, students were divided into small, professionally diverse teams. Responses to ten survey questions (Likert scale) were collected via a web-based platform. These assessments were collected before and after a case-based exercise that provided information to students on the risks of excessive alcohol use as well as the effective screening and team-based management of individuals susceptible to AUD.

RESULTS

Wilcoxon signed-rank analyses revealed that the exercise led to significant decreases in stigma toward individuals engaging in at-risk alcohol use. We also discovered significant increases in self-reported knowledge and confidence in personal qualifications needed to initiate brief interventions to reduce alcohol use. Focused analyses of students from individual health programs uncovered unique improvements according to question theme and health profession.

CONCLUSION

Our findings demonstrate the utility and effectiveness of single, focused IPE-based exercises to impact personal attitudes and confidence in young health professions learners. While additional longitudinal cohort follow-up studies are needed, these results may translate into more effective and collaborative AUD treatment in future clinical settings.

Cross-analyzing addiction specialist and patient opinions and experiences about addictive disorder screening in primary care to identify interaction-related obstacles: a qualitative study

BACKGROUND

Promptly identifying individuals with addictive disorders reduces mortality and morbidity and improves quality of life. Although screening in primary care with the Screening, Brief Intervention and Referral Treatment strategy has been recommended since 2008, it remains underutilized. This may be due to barriers including lack of time, patient reluctance or perhaps the timing and approach for discussing addiction with their patients.

OBJECTIVE

This study aims to explore and cross-analyze patient and addiction specialist experiences and opinions about early addictive disorder screening in primary care to identify interaction-related screening obstacles.

DESIGN AND PARTICIPANTS

Qualitative study with purposive maximum variation sampling among nine addiction specialists and eight individuals with addiction disorders conducted between April 2017 and November 2019 in Val-de-Loire, France.

MAIN MEASURES

Using a grounded theory approach, verbatim data was collected from face-to-face interviews with addiction specialists and individuals with addiction disorders. These interviews explored their opinions and experiences with addiction screening in primary care. Initially, two independent investigators analyzed the coded verbatim according to the data triangulation principle. Secondly, convergences and divergences between addiction specialist and addict verbatim categories were identified, analyzed, and conceptualized.

KEY RESULTS

Four main interaction-related obstacles to early addictive disorder screening in primary care were identified and conceptualized: the new concepts of shared self-censorship and the patient's personal red line, issues not addressed during consultations, and opposition between how physicians and patients would like to approach addictive disorder screening.

CONCLUSIONS

To continue analysis of addictive disorder screening dynamics, further studies to examine the perspectives of all those involved in primary care are required. The information revealed from these studies will provide ideas to help patients and caregivers start discussing addiction and to help implement a collaborative team-based care approach.

Medications for the Treatment of Alcohol Dependence-Current State of Knowledge and Future Perspectives from a Public Health Perspective

No single effective therapy for alcohol abuse has been found, despite it being a serious sociological and economic problem for hundreds of years. It seems difficult to find a single drug as a panacea for the alcohol problem due to the complexity of the pathophysiology of alcohol dependence. The purpose of this narrative review is to review existing and potentially future pharmaceuticals for the treatment of alcohol dependence in the most affordable way possible. Psychotherapy is the mainstay of treatment for alcoholism, while few drugs approved by legislators are available in the augmentation of this treatment, such as acamprosate, disulfiram, and naltrexone, approved by the FDA, and nalmefene by the EMA. There are recent reports in the literature on the possibility of using baclofen, topiramate, varenicline, and gabapentin in the treatment of alcohol dependence. Moreover, the results of recent clinical trials using psychoactive substances such as psilocybin and MDMA appear to be a breakthrough in the modern treatment of alcohol abuse. Despite this initial optimism, a lot of scientific effort is still needed before new pharmacological methods supporting the treatment of alcohol dependence syndrome will be widely available.

"I see myself": Craving imagery among individuals with addictive disorders

Craving has been put forward as a core feature of addictive disorders.

The present qualitative study investigated the experience of craving among individuals with addictive disorders and recent experiences of cravings.

Eleven individuals with Gambling Disorder and ten with Alcohol Use Disorder (n = 21) were recruited. A semi-structured interview explored: (1) modes of thought during craving (mental imagery or verbal thoughts), (2) craving content, (3) coping strategies and (4) craving context.

The thematic analysis showed that cravings were initially dominated by imagery, with a subsequent conflict between imagery and verbal thoughts. Craving content included imagery of preparative rituals, anticipation, and sensory activation, imagery of the addictive behavior "me, there and then imagery" and anticipating that "something good will come out of it." Some participants related to craving as a symptom of sickness, and coping with craving were through distraction, reminding oneself of negative consequences, or via sensory control: avoiding stimuli associated with the addiction. Craving contexts included typical settings of drinking or gambling and engagement of both positive and negative emotions. Alcohol craving was described as an expected relief from internal stimuli, such as anxiety or stress, whereas gambling craving was more often described as an expectancy of financial reward.

Craving was experienced mainly through imagery containing the preparative routines and expected outcomes. Future research and clinical practice should incorporate mode of thought in cravings to better understand its role in the maintenance of the disorders and their treatment.

The preliminary efficacy of virtual agent-assisted intelligent rehabilitation treatment (Echo app v2.0) in patients with alcohol use disorders: Study protocol for a randomized controlled trial

Background

Alcohol use disorder (AUD) is one of the most common substance use disorders. People with AUD are in great need of highly accessible and comprehensive management, involving medicine, exercise, and psychotherapy. However, due to limited resources, providing comprehensive treatment for every patient is challenging. Virtual agent-assisted intelligent rehabilitation treatment can improve the accessibility of comprehensive management.

Objectives

This randomized controlled trial aims to test whether the virtual agent-assisted intelligent rehabilitation treatment (Echo-app-v2.0) plus treatment as usual (TAU) has greater efficacy than only TAU in AUD.

Methods

One hundred participants with AUD will be recruited and randomly assigned to either TAU or virtual agent-assisted intelligent rehabilitation treatment plus TAU based on the 1:1 ratio. The virtual agent-assisted intelligent rehabilitation treatment is delivered by the Echo app v2.0 developed by our research team. Participants will be assessed at baseline, week 4 of treatment, one month, and three months after the end of treatment. The primary outcome is the participants' craving for alcohol, measured by Visual Analogue Scale. Other outcomes include the use of alcohol, motivation for treatment, coping style, depression, anxiety, impulsivity, stress, and sleep quality.

Discussion

The virtual agent, with vivid human image, high privacy, and the ability to interact with users, has the potential to play an important role in the delivery of digital psychotherapy. The development of Echo app v2.0 has the possibility to raise the availability of comprehensive treatment for people with AUD.

Changes in alcohol-related perceptions and behavior among Vietnamese early career doctors after graduation

BACKGROUND: Vietnamese medical students believe becoming “strong” drinkers is important for their future careers working as doctors. However, it is unclear if this is a temporary behaviour associated with life as a student, or a phenomenon associated with the transition to working as a medical practitioner. OBJECTIVE: This study explored changes in alcohol-related perceptions and behaviour among Vietnamese early career doctors working after graduation. METHODS: In-depth interviews were conducted with 15 Vietnamese early career doctors in Hanoi city. Thematic analysis was used to analyse the qualitative data. RESULTS: Vietnamese early career doctors perceived binge drinking as common among doctors, especially male doctors, surgeons, and preventive medicine doctors. This perception was different from when they were medical students because, at that time, they believed doctors would not drink alcohol at hazardous levels. Additionally, Vietnamese early career doctors’ drinking behaviour changed in the frequency and quantity of alcohol consumption after graduation due to peer pressure, job stress, working collaborations, and working environment. CONCLUSIONS: Vietnamese early career doctors changed their alcohol-related perceptions and behaviour after graduation. Gender, mental health (stress), factors related to the working environment, and the role of professional relationships should be considered in strategies to reduce risky alcohol consumption among Vietnamese early career doctors.

Risk Factors for Problematic Drinking in One's Thirties and Forties: A Longitudinal Analysis of the 1970 British Cohort Study

Alcohol drinking and risk factors for problematic drinking may vary across a lifespan. The objective of this study was to identify risk factors for problematic drinking in men and women in their thirties and forties. Alcohol drinking and potential risk factors for problematic drinking were assessed at ages 30, 34, 42, and 46 in the 1970 British Cohort Study. Multilevel models included 10,079 observations in 3880 men and 9241 observations in 3716 women. In men, formerly smoking, currently smoking, having a degree, having malaise, and having a mother who drank while pregnant were independently associated with increased risk of problematic drinking. In women, formerly smoking, currently smoking, being physically active in one's leisure time, having a degree, having a managerial or professional occupation, having malaise, and having a mother who drank while pregnant were independently associated with increased risk of problematic drinking. In men and women, cohabiting as a couple was associated with decreased risk of problematic drinking. This study suggests that several risk factors may be associated with problematic drinking in men and women in their thirties and forties. Policy makers should consider the role of modifiable risk factors in the prevention of problematic drinking.

Epidemiology of trauma in patients with mental disorders

Objectives

We aimed to explore the influence of mental disorders on the risk of developing complications and in-hospital mortality after trauma.

Methods

We conducted an institutional review board-approved cohort study of 23 500 adult patients admitted to the Puerto Rico Trauma Hospital from 2002 to 2019. Participants were divided into 2 groups according to the presence or absence of psychiatric illnesses. Logistic regressions were employed to investigate the effect of mental illness on study outcomes.

Results

Psychiatric illness was associated with higher risk of complications; this risk increased with age. The pattern was accentuated for those with substance use disorders (SUD) and attenuated for those with non-substance-related diagnoses (NSRD). Psychiatric patients with Glasgow Coma Scale (GCS) scores of 15 had a 42% (95% CI 1.17 to 1.73) higher risk of dying, while the opposite was seen for those with scores <15 (adjusted OR=0.79; 95% CI 0.64 to 0.99). SUD was associated with a 51% (95% CI 1.21 to 1.88) higher risk of death in patients with GCS scores of 15, while NSRD was linked to a 49% (95% CI 0.33 to 0.79) lower odds of death among subjects with scores <15.

Conclusions

Our results suggest that trauma patients with SUD are at increased risk of developing complications and those with SUD and GCS scores of 15 are at increased risk of death. Mental health screening is an essential component of the management of trauma patients. Stratifying based on mental health disorders may be helpful during the clinical management of trauma patients, as those with SUD may benefit from more aggressive management.

A Bayesian mixed effects support vector machine for learning and predicting daily substance use disorder patterns

Background: Substance use disorder (SUD) is a heterogeneous disorder. Adapting machine learning algorithms to allow for the parsing of intrapersonal and interpersonal heterogeneity in meaningful ways may accelerate the discovery and implementation of clinically actionable interventions in SUD research.Objectives: Inspired by a study of heavy drinkers that collected daily drinking and substance use (ABQ DrinQ), we develop tools to estimate subject-specific risk trajectories of heavy drinking; estimate and perform inference on patient characteristics and time-varying covariates; and present results in easy-to-use Jupyter notebooks. Methods: We recast support vector machines (SVMs) into a Bayesian model extended to handle mixed effects. We then apply these methods to ABQ DrinQ to model alcohol use patterns. ABQ DrinQ consists of 190 heavy drinkers (44% female) with 109,580 daily observations. Results: We identified male gender (point estimate; 95% credible interval: -0.25;-0.29,-0.21), older age (-0.03;-0.03,-0.03), and time varying usage of nicotine (1.68;1.62,1.73), cannabis (0.05;0.03,0.07), and other drugs (1.16;1.01,1.35) as statistically significant factors of heavy drinking behavior. By adopting random effects to capture the subject-specific longitudinal trajectories, the algorithm outperforms traditional SVM (classifies 84% of heavy drinking days correctly versus 73%). Conclusions: We developed a mixed effects variant of SVM and compare it to the traditional formulation, with an eye toward elucidating the importance of incorporating random effects to account for underlying heterogeneity in SUD data. These tools and examples are packaged into a repository for researchers to explore. Understanding patterns and risk of substance use could be used for developing individualized interventions.

Efficacy of screening and brief intervention for hazardous alcohol use in patients with mood disorders: A randomized clinical trial from a psychiatric out-patient clinic in India

AIM

To determine the efficacy of individual-based, face-to-face screening and brief intervention (SBI) for hazardous alcohol use among treatment-seeking outpatients with mood disorders.

METHODS

It was a parallel-group, single-blind, randomized controlled trial of 84 participants who met the selection criteria for hazardous alcohol use, defined by alcohol use disorder identification test (AUDIT) score 8-19. Participants were randomly allocated to either SBI or general advice group. Both groups had received a standard care for mood disorders. The outcome was assessed after 3 months. The primary outcome was a change in the mean AUDIT score and the secondary outcomes were a change in frequency of heavy episodic drinking and stages of motivation.

RESULTS

Majority (60%) had major depressive episodes. There was no significant difference in baseline demography and clinical variables between the groups. Both intention to treat and per-protocol analyses showed a small but significant effect of SBI on mean AUDIT score. Age, baseline AUDIT, and motivation did not moderate the effect. SBI was associated with a significant decrease in the frequency of heavy drinking and improvement in stages of motivation.

CONCLUSION

SBI among patients with mood disorders had a small but significant effect on alcohol use.

Prevalence of at-risk drinking recognition: A systematic review and meta-analysis

BACKGROUND

There is a prominent "treatment gap" in relation to at-risk drinking (ARD), whereby a minority of at-risk drinkers ever access treatment. Research suggests that recognition of problem drinking is a necessary precursor for help-seeking and treatment.

OBJECTIVE

This systematic review and meta-analysis aimed to estimate the prevalence of ARD recognition within those meeting criteria for ARD.

METHOD

PsycINFO, Web of Science, Scopus, and MEDLINE were searched using the terms: problem* AND (recogni* OR perceive* OR perception OR self-identif*) AND alcohol - to identify studies published in English between 2000 and 2022. Studies reported the frequency (weighted or unweighted) of participants meeting ARD criteria that also directly identified ARD, perceived a need for help, or endorsed a readiness to change. The prevalence of ARD recognition was estimated using a random-effects meta-analysis with 95% confidence intervals (CIs).

RESULTS

17 studies were included which provided data for 33,349 participants with ARD. Most (n = 14) were US studies. ARD was self-identified via a single indicator in 7 studies, whereas recognition was assessed via stages of change in 4 studies and need for help in 6 studies. The pooled prevalence of ARD recognition was 31% (95% CI: 25%-36%), and subgroup analyses indicated alcohol use severity, measure of recognition, and population type to be significant sources of heterogeneity.

CONCLUSIONS

Most individuals with ARD fail to recognise their drinking problem so preventive approaches that promote recognition may be helpful. However, we must be cautious of how inconsistency in question framing affects self-reported problem recognition.

Alcohol brief intervention, specialty treatment and drinking outcomes at 12 months: Results from a systematic alcohol screening and brief intervention initiative in adult primary care

BACKGROUND

Alcohol screening, brief intervention and referral to treatment (SBIRT) in adult primary care is an evidence-based, public health strategy to address unhealthy alcohol use, but evidence of effectiveness of alcohol brief intervention (ABI) in real-world implementation is lacking.

METHODS

We fit marginal structural models with inverse probability weighting to estimate the causal effects of ABI on 12-month drinking outcomes using longitudinal electronic health records data for 312,056 adults with a positive screening result for unhealthy drinking between 2014 and 2017 in a large healthcare system that implemented systematic primary care-based SBIRT. We examined effects of ABI with and without adjusting for receipt of specialty alcohol use disorder (AUD) treatment, and whether effects varied by patient demographic characteristics and alcohol use patterns.

RESULTS

Receiving ABI resulted in significantly greater reductions in heavy drinking days (mean difference [95% CI] = -0.26 [-0.45, -0.08]), drinking days per week (-0.04 [-0.07, -0.01]), drinks per drinking day (-0.05 [-0.08, -0.02]) and drinks per week (-0.16 [-0.27, -0.04]). Effects of ABI on 12-month drinking outcomes varied by baseline consumption level, age group and whether patients already had an AUD, with better improvement in those who were drinking at levels exceeding only daily limits, younger, and without an AUD.

CONCLUSIONS

Systematic ABI in adult primary care has the potential to reduce drinking among people with unhealthy drinking considerably on both an individual and population level. More research is needed to help optimize ABI, in particular tailoring it to diverse sub-populations, and studying its long-term public health impact.

Clinical moderators of response to nalmefene in a randomized-controlled trial for alcohol dependence: An exploratory analysis

BACKGROUND

Nalmefene is the only medication marketed to reduce the consumption of alcohol in patients with alcohol dependence, but it remains unclear which patients could most benefit from it. This study aimed to identify clinical moderators that affect treatment response to nalmefene in patients with alcohol dependence.

METHODS

In a multicenter, randomized, controlled, double-blind, phase 3 study of nalmefene on Japanese patients with alcohol dependence, the relationship between the reduction of heavy drinking days (HDD) and total alcohol consumption (TAC) at 12 and 24 weeks of treatment and baseline variables of the participants were analyzed in a linear regression and multiple adjusted analysis.

RESULTS

Age < 65, no family history of problem drinking, age at onset of problem drinking ≥ 25, and not currently smoking were possible positive moderators. Nalmefene showed a significant HDD reduction in patients with age < 65 or no family history of problem drinking, and a significant TAC reduction in patients with age at onset of problem drinking ≥ 25 or who were not currently smoking. After multiple adjusted analyses, age < 65 (p = .028), no family history of problem drinking (p = .047), and age at onset of problem drinking ≥ 25 (p = .030) were statistically significant. Not currently smoking (p = .071) was marginally significant. In combination, these moderators indicated synergistic effects.

CONCLUSIONS

Alcohol-dependent patients with favorable prognostic factors such as non-smoking status, no family history of problem drinking, and a late-onset of problem drinking selectively benefit from nalmefene. Further research is needed to validate these exploratory results.

Evaluating risk for alcohol use disorder: Polygenic risk scores and family history

BACKGROUND

Early identification of individuals at high risk for alcohol use disorder (AUD) coupled with prompt interventions could reduce the incidence of AUD. In this study, we investigated whether Polygenic Risk Scores (PRS) can be used to evaluate the risk for AUD and AUD severity (as measured by the number of DSM-5 AUD diagnostic criteria met) and compared their performance with a measure of family history of AUD.

METHODS

We studied individuals of European ancestry from the Collaborative Study on the Genetics of Alcoholism (COGA). DSM-5 diagnostic criteria were available for 7203 individuals, of whom 3451 met criteria for DSM-IV alcohol dependence or DSM-5 AUD and 1616 were alcohol-exposed controls aged ≥21 years with no history of AUD or drug dependence. Further, 4842 individuals had a positive first-degree family history of AUD (FH+), 2722 had an unknown family history (FH?), and 336 had a negative family history (FH-). PRS were derived from a meta-analysis of a genome-wide association study of AUD from the Million Veteran Program and scores from the problem subscale of the Alcohol Use Disorders Identification Test in the UK Biobank. We used mixed models to test the association between PRS and risk for AUD and AUD severity.

RESULTS

AUD cases had higher PRS than controls with PRS increasing as the number of DSM-5 diagnostic criteria increased (p-values ≤ 1.85E-05 ) in the full COGA sample, the FH+ subsample, and the FH? subsample. Individuals in the top decile of PRS had odds ratios (OR) for developing AUD of 1.96 (95% CI: 1.54 to 2.51, p-value = 7.57E-08 ) and 1.86 (95% CI: 1.35 to 2.56, p-value = 1.32E-04 ) in the full sample and the FH+ subsample, respectively. These values are comparable to previously reported ORs for a first-degree family history (1.91 to 2.38) estimated from national surveys. PRS were also significantly associated with the DSM-5 AUD diagnostic criterion count in the full sample, the FH+ subsample, and the FH? subsample (p-values ≤6.7E-11 ). PRS remained significantly associated with AUD and AUD severity after accounting for a family history of AUD (p-values ≤6.8E-10 ).

CONCLUSIONS

Both PRS and family history were associated with AUD and AUD severity, indicating that these risk measures assess distinct aspects of liability to AUD traits.

Testing an mHealth System for Individuals With Mild to Moderate Alcohol Use Disorders: Protocol for a Type 1 Hybrid Effectiveness-Implementation Trial

Background

The extent of human interaction needed to achieve effective and cost-effective use of mobile health (mHealth) apps for individuals with mild to moderate alcohol use disorder (AUD) remains largely unexamined. This study seeks to understand how varying levels of human interaction affect the ways in which an mHealth intervention for the prevention and treatment of AUDs works or does not work, for whom, and under what circumstances.

Objective

The primary aim is to detect the effectiveness of an mHealth intervention by assessing differences in self-reported risky drinking patterns and quality of life between participants in three study groups (self-monitored, peer-supported, and clinically integrated). The cost-effectiveness of each approach will also be assessed.

Methods

This hybrid type 1 study is an unblinded patient-level randomized clinical trial testing the effects of using an evidence-based mHealth system on participants’ drinking patterns and quality of life. There are two groups of participants for this study: individuals receiving the intervention and health care professionals practicing in the broader health care environment. The intervention is a smartphone app that encourages users to reduce their alcohol consumption within the context of integrative medicine using techniques to build healthy habits. The primary outcomes for quantitative analysis will be participant data on their risky drinking days and quality of life as well as app use from weekly and quarterly surveys. Cost measures include intervention and implementation costs. The cost per participant will be determined for each study arm, with intervention and implementation costs separated within each group. There will also be a qualitative assessment of health care professionals’ engagement with the app as well as their thoughts on participant experience with the app.

Results

This protocol was approved by the Health Sciences Minimal Risk Institutional Review Board on November 18, 2019, with subsequent annual reviews. Recruitment began on March 6, 2020, but was suspended on March 13, 2020, due to the COVID-19 pandemic restrictions. Limited recruitment resumed on July 6, 2020. Trial status as of November 17, 2021, is as follows: 357 participants were enrolled in the study for a planned enrollment of 546 participants.

Conclusions

The new knowledge gained from this study could have wide and lasting benefits related to the integration of mHealth systems for individuals with mild to moderate AUDs. The results of this study will guide policy makers and providers toward cost-effective ways to incorporate technology in health care and community settings.

Epidemiology of DSM-5 alcohol use disorder in U.S. military veterans: Results from the National Health and Resilience in Veterans Study

BACKGROUND

Alcohol use disorder (AUD) is a prevalent public health concern in the U.S. that disproportionately affects veterans relative to civilians. Given changes to the demographic composition of the veteran population and AUD diagnostic criteria in the DSM-5, updated knowledge regarding the epidemiology of DSM-5 AUD in a national sample of veterans is critical to informing the population-based burden of this disorder.

METHODS

Data were analyzed from the National Health and Resilience in Veterans Study, which surveyed a nationally representative sample of 4069 U.S. veterans. Lifetime DSM-5 AUD (mild, moderate, severe) and past-year DSM-5 AUD were assessed using validated self-report measures, and sociodemographic, military, and psychiatric characteristics associated with lifetime and past-year AUD were evaluated.

RESULTS

Prevalences of lifetime and past-year DSM-5 AUD were 40.8% (95% confidence interval [CI]=39.2-42.3%) and 10.5% (95%CI=9.6-11.5%), respectively. Lifetime prevalences of mild, moderate, and severe AUD were 20.5%, 8.3%, and 12.0%, respectively. Veterans with lifetime AUD had elevated rates of psychiatric disorders and suicidal behavior, which generally increased as a function of AUD severity. Lifetime AUD was also associated with being younger, male, white, unmarried, retired and experiencing more adverse childhood experiences and traumas. For past-year AUD, being younger, male, white, having more adverse childhood experiences, and experiencing lifetime PTSD were significant correlates.

CONCLUSIONS

AUD is highly prevalent among U.S. veterans and associated with substantial psychopathology, including elevated odds of suicidal behaviors. Results underscore the importance of comprehensive screening and preventive efforts for AUD, and interventions that concurrently target overlapping alcohol use and psychiatric difficulties.

Occupational health care personnel tackling alcohol overuse - an observational study of work processes and patient characteristics

Background

Overuse of alcohol is a significant risk factor for early retirement. This observational study investigated patient characteristics and work processes in occupational health care (OHC) affecting practices in tackling alcohol overuse.

Methods

The data were from 3089 patient contacts gathered for quality improvement purposes in fifteen OHC units during the years 2013–2019 in Finland. A two-proportion z-test was performed to find associations between reason for contact, and 17 other factors, and the probability of alcohol use being checked and overuse tackled.

Results

OHC personnel checked alcohol use twice as often with male patients as with female patients. Employees at risk of needing sick leave were checked for alcohol use more often (55.4, 95% confidence interval 49.2–61.6%) than those on > 30-day sick leave or working with permanent work disability (p < 0.01). Alcohol use was checked in 64.1% (59.5–68.7%) of patients while making an individual health promotion plan compared to 36.9% of those without a plan (33.1–40.6%, p < 0.0001). Patients with depression were actively checked for alcohol use, especially in cases of major depression (72.7%, 64.0–81.0%). Work processes in which OHC should have been more active in checking and tackling alcohol use included assessing the need for rehabilitation (36.5%, 32.0–41.0%) and health check-ups (HCUs) for mental reasons (43.8%, 38.1–49.4%). HCUs where alcohol overuse was detected led to brief interventions to tackle the overuse in 58.1% (43.4–72.9%) of cases.

Conclusions

The study showed factors that increased OHC personnel’s practices in checking and tackling alcohol use and work processes where the activity should be improved. Discussions about alcohol use took place more often with working-aged men than women, the younger the more. OHC personnel checked actively alcohol use with patients in danger of sick leave, patients treated for depression, while making an individual health promotion plan, and in planned HCUs with a confirmed protocol. More improvement is needed to conduct brief interventions in disability prevention processes, and especially when overuse is detected.

Impulsive trait mediates the relationship between white matter integrity of prefrontal-striatal circuits and the severity of dependence in alcoholism

BACKGROUND

Alcohol dependence (AD) remains one of the major public health concerns. Impulsivity plays a central role in the transfer from recreational alcohol use to dependence and relapse. White matter dysfunction has been implicated in alcohol addiction behaviors and impulsivity. However, little is known about the role of systematic striatal structural connections underlying the mechanism of impulsive traits in AD.

METHODS

In our study, we used seed-based classification by probabilistic tractography with five target masks of striatal circuits to explore the differences in white matter integrity (fractional anisotropy, FA) in AD male patients (N = 51) and healthy controls (N = 27). We mainly explored the correlation between FA of the striatal circuits and impulsive traits (Barratt Impulsiveness Scale, BIS-11), and the mediation role of impulsivity in white matter integrity and the severity of alcohol dependence.

RESULTS

Compared with healthy controls, AD showed much lower FA in the left and right striatum-supplementary motor area (SMA) and left striatum-amygdala. We also found the decreased FA of right striatum-vlPFC was correlated with higher impulsivity. Besides, the relationship between reduced FA of right striatum-vlPFC and severity of dependence could be mediated by impulsivity.

CONCLUSION

In our study, we found disrupted white matter integrity in systematic striatal circuits in AD and the decreased FA of right striatum-vlPFC was correlated with higher impulsivity in AD. Our main findings provide evidence for reduced white matter integrity of systematic striatal circuits and the underlying mechanisms of impulsivity in male AD individuals.

The Danish RESPEKT Campaign: Impact of a National Mass Media Campaign Aiming to Increase Treatment Seeking for Alcohol Use Disorders

Background: A minority of all with alcohol use disorders seek treatment. In Denmark, a media campaign, "RESPEKT," has been broadcast nationwide since 2015. The campaign is unique from an international perspective and aims to increase treatment-seeking. Similar interventions have, up until now, not been scientifically evaluated.Aim: To investigate campaign awareness, understanding, attitudes, and information-seeking pre- and post the campaign period. Also, associations to demographic factors and year of campaign will be investigated.Method: Study design: Repeated cross-sectional studyParticipants: Adults aged 30-70 years, in total n = 9169.Data: Pre- and post the campaign period between 2017 and 2020, an online questionnaire was administered by a market research company. The questionnaire covered demographic data, campaign awareness, understanding, attitudes, and information-seeking about treatment for alcohol use disorders. In addition, complete-case logistic regression was performed to model dichotomous outcomes, and odds ratios were calculated.Results: Campaign awareness varied between 8 and 40% over the different years. Understanding of the main message was high and received higher endorsements over the study period. A majority expressed positive attitudes toward the campaign and support for the main message regarding free treatment. However, very few self-reported seeking information about AUD treatment. Female sex was associated with higher awareness of the campaign, higher understanding and more positive attitudes toward the campaign.Conclusion: The campaign evoked positive attitudes and had an impact on increasing knowledge and changing attitudes. However, no effect on self-reported information seeking about treatment was found.
