Clinical Reasoning and Challenges Faced With Onset Psychotic Symptoms in a Case of Combined Huntington's Disease and Gayet-Wernicke Encephalopathy.

Physicians are occasionally confronted with patients presenting psychotic symptoms of organic origin. Therefore, precision in diagnosing the organic basis is pivotal for targeted treatment, addressing the underlying etiology. This case study delineates the nuanced phases of clinical reasoning employed to ascertain a diagnosis of Huntington's disease (HD), notably amidst concurrent alcohol dependence. A comprehensive clinical examination and meticulous review of the patient's medical history served as linchpins in guiding subsequent investigations toward identifying the etiological underpinnings of the psychotic symptomatology. Furthermore, this case sheds light on the uncommon overlap of HD and Wernicke's encephalopathy, compounding diagnostic complexities, especially given the polymorphic nature of HD. The diagnostic intricacies needed precise analysis of the clinical picture and a deep understanding of potential interactions between neurological pathologies and the deleterious effects of alcoholism on the nervous system.

Associations between alcohol use and outcome of psychological treatment in specialist psychiatric care - a cohort study.

Background: Alcohol-related issues are widespread worldwide and are fairly substantial. Numerous studies have identified and clarified the effects and prevalence of alcohol use across different contexts. However, when it comes to the prevalence of alcohol in psychiatry and its impact on treatment outcomes compared to other patient groups, studies are relatively scarce, and results often vary, sometimes with different outcomes. This study focuses on investigating the effectiveness of psychological treatment in psychiatric clinics for outpatients, considering those with and without hazardous alcohol use under naturalistic conditions. Methods: Patients were recruited between 2012 and 2016 from psychiatric clinics in Sormland, Sweden, as part of the regular services. Patients completed symptom assessment instruments regarding depression, anxiety, quality-of-life, and alcohol consumption at the beginning of their psychological treatment, upon completion, and during a follow-up 1 year after completion. Completion of questionnaires was ongoing for some patients until 2021. A total of 324 patients were included in the study, distributed among 59 participating therapists. Results: Among all patients in the study, 30.2% showed hazardous alcohol use at the start of their psychological treatment, with a higher proportion being men. There was a significant reduction in the proportion of patients with hazardous use and a notable decrease in the mean audit score upon completion of psychological treatment. At follow-up, there was no significant change compared to completion. There were 31.2% of the patients who achieved recovery or improvement in the audit score upon completion of treatment. Patients with hazardous alcohol use consistently scored higher mean values on the symptom assessment instruments and lower on the quality-of-life instrument at the beginning. More individuals with hazardous alcohol use typically achieved better results across all outcome instruments at both at completion and follow-up. Conclusion: Patients with hazardous alcohol use demonstrate significant improvements in their alcohol consumption through standard psychological treatment in psychiatry, despite the treatment not specifically focusing on alcohol consumption. The progress/improvement appears to be largely maintained at follow-up. Moreover, patients with hazardous alcohol use tend to show greater progress across all outcome instruments. No significant gender differences were detected in this context.

Study of Association of Erectile Dysfunction in male subjects with the severity of Alcohol Dependence.

Background: Alcohol dependence syndrome is a major public health problem, and it impacts the social, psychological, medical, economic, and religious spheres of our existence. Persistent alcohol abuse impacts sexual functioning negatively and leads to the onset of sexual dysfunction. Aim: This study was conducted to determine erectile dysfunction in males diagnosed with alcohol dependence syndrome and its association with the severity of alcohol dependence. Materials and Methods: The descriptive, non-interventional, cross-sectional study was conducted at the Department of Psychiatry in a tertiary care hospital where 78 subjects diagnosed with alcohol dependence syndrome were assessed for severity of dependence with the Severity of Alcohol Dependence Questionnaire (SADQ-C). Erectile dysfunction in these subjects was assessed with the International Index of Erectile Function scale (IIEF) and the severity of the same was correlated with the severity of alcohol dependence. Results: The results of our study indicated that erectile dysfunction was common in individuals having alcohol dependence syndrome and its severity was positively correlated with the severity of alcohol dependence. Unidentified sexual dysfunction may perpetuate alcohol dependence with poor response to deaddiction therapy. This information about sexual dysfunction due to alcohol dependence can also be used in motivational counseling of heavy drinkers to provide an impetus for change. Conclusions: The prevalence of erectile dysfunction was significantly higher than that of the general population. The same was significantly elevated in patients with severe alcohol dependence as compared to those with mild/moderate alcohol dependence.

Causal effect of physical activity and sedentary behavior on the risk of alcohol dependence: A bidirectional two-sample Mendelian randomization study.

BACKGROUND: Alcohol dependence, influenced by physical activity (PA) and sedentary behavior, lacks clear causal clarity. This study aims to clarify causal relationships by estimating these effects using bidirectional two-sample Mendelian randomization (MR). METHODS: A bidirectional multivariable two-sample MR framework was employed to assess the causal effects of PA and sedentary behavior on alcohol dependence. Summarized genetic association data were analyzed for four PA-related activity patterns-moderate to vigorous physical activity (MVPA), vigorous physical activity (VPA), accelerometer-based physical activity with average acceleration (AccAve), and accelerometer-based physical activity with accelerations greater than 425 milli-gravities (Acc425)-and three sedentary behavior patterns-sedentary, TV watching, and computer use. The study was expanded to include the examination of the relationship between sedentary behavior or PA and general drinking behavior, quantified as drinks per week (DPW). We obtained summarized data on genetic associations with four PA related activity patterns (MVPA, VPA, AccAve and Acc425) and three sedentary behavior related behavior patterns (sedentary, TV watching and computer use). RESULTS: MR analysis found AccAve inversely associated with alcohol dependence risk (OR: 0.87; 95% CI: 0.80-0.95; p < 0.001), MVPA positively associated (OR: 2.86; 95%CI: 1.45-5.66; p = 0.002). For sedentary behavior and alcohol dependence, only TV watching was positively associated with the risk of alcohol dependence (OR: 1.43; 95%CI: 1.09-1.88; p = 0.009). No causal links found for other physical or sedentary activities. Reverse analysis and sensitivity tests showed consistent findings without pleiotropy or heterogeneity. Multivariate MR analyses indicated that while MVPA, AccAve and TV watching are independently associated with alcohol dependence, DPW did not show a significant causal relationship. CONCLUSIONS: Our results suggest that AccAve is considered a protective factor against alcohol dependence, while MVPA and TV watching are considered risk factors for alcohol dependence. Conversely, alcohol dependence serves as a protective factor against TV watching. Only TV watching and alcohol dependence might mutually have a significant causal effect on each other.

Correlation of striatal dopamine D2/3 receptor availability with GABA level in the anterior cingulate cortex in healthy controls but not in alcohol-dependent subjects and individuals at high risk: A multimodal magnetic resonance spectroscopy and positron emission tomography study.

BACKGROUND: The association of impaired dopaminergic neurotransmission with the development and maintenance of alcohol use disorder is well known. More specifically, reduced dopamine D2/3 receptors in the striatum of subjects with alcohol dependence (AD) compared to healthy controls have been found in previous studies. Furthermore, alterations of gamma-aminobutyric acid (GABA) and glutamate (Glu) levels in the anterior cingulate cortex (ACC) of AD subjects have been documented in several studies. However, the interaction between cortical Glu levels and striatal dopamine D2/3 receptors has not been investigated in AD thus far. METHODS: This study investigated dopamine D2/3 receptor availability via 18F-fallypride positron emission tomography (PET) and GABA as well as Glu levels via magnetic resonance spectroscopy (MRS) in 19 detoxified AD subjects, 18 healthy controls (low risk, LR) controls and 19 individuals at high risk (HR) for developing AD, carefully matched for sex, age and smoking status. RESULTS: We found a significant negative correlation between GABA levels in the ACC and dopamine D2/3 receptor availability in the associative striatum of LR but not in AD or HR individuals. Contrary to our expectations, we did not observe a correlation between Glu concentrations in the ACC and striatal D2/3 receptor availability. CONCLUSIONS: The results may reflect potential regulatory cortical mechanisms on mesolimbic dopamine receptors and their disruption in AD and individuals at high risk, mirroring complex neurotransmitter interactions associated with the pathogenesis of addiction. This is the first study combining 18F-fallypride PET and MRS in AD subjects and individuals at high risk.

Effect of family intervention on relapse rate of Chinese patients with alcohol-dependent.

Objective: This study explored the impact of a family intervention on the relapse rate of Chinese patients with alcohol dependence. Methods: A total of 151 male patients with alcohol dependence who were discharged from the Substance Dependence Department of the Wenzhou Seventh People's Hospital from January to December 2020 were selected. They were divided into the control (n = 73) and experimental (n = 78) groups. Patients in both groups received routine alcohol cessation treatment. Moreover, patients in the experimental group were followed up by a professional psychiatrist to carry out individual family intervention. The Family Function Rating Scale (FAD), a Self-made general information questionnaire, and the Chinese version of the Family Intimacy and Adaptability Scale (FACESI-CV) were performed. Re-drinking rate and readmission rate were assessed. Results: Family intervention could reduce relapse rate (31, 39.74%) and rehospitalization (27, 34.62%) compared with the control group. After family training, FAD factor scores were improved in the experiment group in comparison with the control group. Family training improved communication (18.2 ± 3.7), role (20.8 ± 2.5), emotional response (10.8 ± 1.8), emotional involvement (13.7 ± 1.2), behavioral control (19.8 ± 1.2), and overall functionality (23.5 ± 2.1) in the experiment group in comparison with the control group. After family training, intimacy (70.5 ± 8.7) and adaptability (64.1 ± 6.9) in the experiment group was higher than in the control group. After family intervention, Michigan Alcohol Dependence Scale (MAST) (9.21 ± 0.68) and Short-Form 36 (SF-36) (80.32 ± 4.47) in the experiment group were higher than the control group. Conclusion: Family intervention for families of patients with alcohol dependence can improve their family function, increase their family intimacy and adaptability, and reduce the rate of relapse.

Changes in processing speed during early abstinence from alcohol dependence.

BACKGROUND: Processing speed is a task-independent construct underpinning more complex goal-related abilities. Processing speed is impaired in alcohol dependence (AD) and is linked to relapse, as are the functions it underpins. Reliable measurement of processing speed may allow tracking of AD recovery trajectories and identify patients requiring additional support. AIMS: To assess changes in reaction time (RT) from baseline (at the start of a detoxification programme) across early abstinence. METHODS: Vibrotactile RT was assessed in early recovery between days 3 and 7 of treatment in 66 individuals with AD (25 females; aged 19-74, 44.60 ± 10.60 years) and against 35 controls tested on one occasion (19 females; 41.00 ± 13.60), using two multivariate multiple regressions. A mixed multivariate analysis of covariance (MANCOVA) of available AD data (n = 45) assessed change in RT between timepoints and between treatment settings (outpatient vs inpatient). RESULTS: The group (AD vs control) significantly predicted choice RT at baseline and follow-up but did not significantly predict simple RT or RT variability, which is inconsistent with previous findings. At follow-up, mental fatigue was also predicted by the group, and MANCOVA indicated that this had worsened in inpatients but improved in outpatients. CONCLUSIONS: Recovery of RT measures so early in the treatment journey was not in line with previous research which indicates persisting deficits. The interaction between setting and timepoint indicates that despite being typically less medically complex, outpatients require ongoing support and monitoring during their recovery.

Clustering care pathways of people with alcohol dependence using a data linkage of routine data in Bremen, Germany.

BACKGROUND: Although many individuals with alcohol dependence (AD) are recognized in the German healthcare system, only a few utilize addiction-specific treatment services. Those who enter treatment are not well characterized regarding their prospective pathways through the highly fragmented German healthcare system. This paper aims to (1) identify typical care pathways of patients with AD and their adherence to treatment guidelines and (2) explore the characteristics of these patients using routine data from different healthcare sectors. METHODS: We linked routinely collected register data of individuals with a documented alcohol-related diagnosis in the federal state of Bremen, Germany, in 2016/2017 and their addiction-specific health care: two statutory health insurance funds (outpatient pharmacotherapy for relapse prevention and inpatient episodes due to AD with and without qualified withdrawal treatment (QWT)), the German Pension Insurance (rehabilitation treatment) and a group of communal hospitals (outpatient addiction care). Individual care pathways of five different daily states of utilized addiction-specific treatment following an index inpatient admission due to AD were analyzed using state sequence analysis and cluster analysis. The follow-up time was 307 days (10 months). Individuals of the clustered pathways were compared concerning current treatment recommendations (1: QWT followed by postacute treatment; 2: time between QWT and rehabilitation). Patients' characteristics not considered during the cluster analysis (sex, age, nationality, comorbidity, and outpatient addiction care) were then compared using a multinomial logistic regression. RESULTS: The analysis of 518 individual sequences resulted in the identification of four pathway clusters differing in their utilization of acute and postacute treatment. Most did not utilize subsequent addiction-specific treatment after their index inpatient episode (n = 276) or had several inpatient episodes or QWT without postacute treatment (n = 205). Two small clusters contained pathways either starting rehabilitation (n = 26) or pharmacotherapy after the index episode (n = 11). Overall, only 9.3% utilized postacute treatment as recommended. CONCLUSIONS: A concern besides the generally low utilization of addiction-specific treatment is the implementation of postacute treatments for individuals after QWT.

Abstinence and Fear Experienced during This Period Produce Distinct Cortical and Hippocampal Adaptations in Alcohol-Dependent Rats.

Previous studies demonstrate that ethanol dependence induced by repeating cycles of chronic intermittent ethanol vapor exposure (CIE) followed by protracted abstinence produces significant gray matter damage via myelin dysfunction in the rodent medial prefrontal cortex (mPFC) and alterations in neuronal excitability in the mPFC and the dentate gyrus (DG) of the hippocampus. Specifically, abstinence-induced neuroadaptations have been associated with persistent elevated relapse to drinking. The current study evaluated the effects of forced abstinence for 1 day (d), 7 d, 21 d, and 42 d following seven weeks of CIE on synaptic plasticity proteins in the mPFC and DG. Immunoblotting revealed reduced expression of CaMKII in the mPFC and enhanced expression of GABAA and CaMKII in the DG at the 21 d time point, and the expression of the ratio of GluN2A/2B subunits did not change at any of the time points studied. Furthermore, cognitive performance via Pavlovian trace fear conditioning (TFC) was evaluated in 3 d abstinent rats, as this time point is associated with negative affect. In addition, the expression of the ratio of GluN2A/2B subunits and a 3D structural analysis of neurons in the mPFC and DG were evaluated in 3 d abstinent rats. Behavioral analysis revealed faster acquisition of fear responses and reduced retrieval of fear memories in CIE rats compared to controls. TFC produced hyperplasticity of pyramidal neurons in the mPFC under control conditions and this effect was not evident or blunted in abstinent rats. Neurons in the DG were unaltered. TFC enhanced the GluN2A/2B ratio in the mPFC and reduced the ratio in the DG and was not altered by abstinence. These findings indicate that forced abstinence from CIE produces distinct and divergent alterations in plasticity proteins in the mPFC and DG. Fear learning-induced changes in structural plasticity and proteins contributing to it were more profound in the mPFC during forced abstinence.

Ketamine in Substance Use Disorder Treatment: A Narrative Review.

Substance use disorder (SUD) continues to pose a significant global health challenge, necessitating innovative and effective therapeutic interventions. Ketamine, traditionally recognized for its anesthetic properties, has emerged as a novel and promising avenue for the treatment of SUD. This narrative review critically examines the current body of literature surrounding the use of ketamine in various forms and settings for individuals grappling with substance abuse. The review explores the neurobiological underpinnings of ketamine's potential therapeutic effects in SUD, shedding light on its impact on glutamatergic neurotransmission, neuroplasticity, and reward pathways. Special attention is given to the psychotropic and dissociative properties of ketamine, exploring their implications for both therapeutic outcomes and patient experience. Ultimately, this review aims to provide a comprehensive overview of the current state of knowledge regarding ketamine's role in the treatment of SUD, emphasizing the need for further research and clinical exploration. As we navigate the complex terrain of addiction medicine, understanding the nuances of ketamine's potential in SUD holds promise for the development of more effective and personalized therapeutic strategies.

Altered individual gray matter structural covariance networks in early abstinence patients with alcohol dependence.

While alterations in cortical thickness have been widely observed in individuals with alcohol dependence, knowledge about cortical thickness-based structural covariance networks is limited. This study aimed to explore the topological disorganization of structural covariance networks based on cortical thickness at the single-subject level among patients with alcohol dependence. Structural imaging data were obtained from 61 patients with alcohol dependence during early abstinence and 59 healthy controls. The single-subject structural covariance networks were constructed based on cortical thickness data from 68 brain regions and were analyzed using graph theory. The relationships between network architecture and clinical characteristics were further investigated using partial correlation analysis. In the structural covariance networks, both patients with alcohol dependence and healthy controls displayed small-world topology. However, compared to controls, alcohol-dependent individuals exhibited significantly altered global network properties characterized by greater normalized shortest path length, greater shortest path length, and lower global efficiency. Patients exhibited lower degree centrality and nodal efficiency, primarily in the right precuneus. Additionally, scores on the Alcohol Use Disorder Identification Test were negatively correlated with the degree centrality and nodal efficiency of the left middle temporal gyrus. The results of this correlation analysis did not survive after multiple comparisons in the exploratory analysis. Our findings may reveal alterations in the topological organization of gray matter networks in alcoholism patients, which may contribute to understanding the mechanisms of alcohol addiction from a network perspective.

Women and shame: narratives of recovery from alcohol dependence.

OBJECTIVE: Existing literature indicates distinct pathways and the key role of shame and stigma into alcohol dependence (AD) and recovery for women. Internationally, there is a paucity of research exploring these factors from women's perspectives. METHODS AND MEASURES: Taking a critical realist epistemological position, unstructured life story interviews were analysed via narrative analysis to explore how seven women from the UK, storied shame in their recovery from AD. RESULTS: Shame followed a common trajectory across participants' stories, appearing as a reoccurring factor throughout AD and recovery. Participants narrated shame as gendered, contributing to a loss of personal control in defining a valued personal identity. Drinking began as a shame-management strategy but evolved into a source of shame, compounded by fears of being labelled an 'alcoholic woman'. Recovery involved reclaiming the self through de-shaming a shame-based identity and developing a positive, non-drinking identity. By evaluating 'shaming' recovery frameworks, sharing stories and reconstructing their own, participants were able to work through shame, resist pathologising identity labels and internalise esteemed 'sober' identities. CONCLUSION: This research provides important insights into the intersection between shame, identity, gender and culture in women's recovery from AD. Implications for clinical practice, future research and policy are considered.

Prevalence, sociodemographic, and clinical correlates of underweight in a sample of Chinese male alcohol-dependent patients.

BACKGROUND: Underweight is a significant symptom in alcohol-dependent patients, yet few studies have examined underweight in Chinese male patients. The current study aimed to identify the prevalence, sociodemographic, and clinical correlates of underweight in Chinese male patients with alcohol dependency. METHODS: In this cross-sectional study, 405 male inpatients with alcohol dependence and 383 healthy male controls were recruited. Participants' demographic and clinical data, including anthropometric data, were collected. We first conducted univariate analysis to identify seven variables with significant differences between groups: smoking behavior, hospitalization, alcohol consumption, cerebral infarction, hypertension, Hamilton Depression Scale (HAMD) score, and Scale for Assessment of Negative Symptom (SANS) score. Then, binary logistic regression was used to assess their relationship with underweight, with a significance level of .05. RESULTS: The prevalence of underweight was significantly higher in the study population than in the control group (2.99% vs. 2.87%; P < .001). Patients with underweight had significantly higher rates of smoking behavior and cerebral infarction, as well as higher scores of SANS and HAMD than non-underweight patients. The non-underweight patients had higher daily alcohol consumption and times of hospitalization. Furthermore, logistic regression analysis showed that smoking behavior [odds ratio (OR) = 2.84, 95% confidence interval (CI) = 1.03-7.80, P = .043)], cerebral infarction (OR = 5.20, 95% CI = 1.13-23.85, P = .036), SANS score (OR = 1.22, 95% CI = 1.16-1.28, P < .001), and HAMD score (OR = 1.06, 95% CI = 1.02-1.11, P = .005) were associated with underweight. CONCLUSIONS: More than 20% of male alcohol-dependent patients in a Chinese sample were underweight. Some demographic and clinical variables independent correlates for underweight in alcohol-dependent patients. We need to focus on alcohol-dependent patients with smoking, cerebral infarction, depression, and more prominent negative symptoms.

Functional Connectivity Differences in the Resting-state of the Amygdala in Alcohol-dependent Patients with Depression.

RATIONALE AND OBJECTIVES: The mechanism of comorbidity between alcohol dependence and depressive disorders are not well understood. This study investigated differences in the brain function of alcohol-dependent patients with and without depression by performing functional connectivity analysis using resting-state functional magnetic resonance imaging. MATERIALS AND METHODS: A total of 29 alcohol-dependent patients with depression, 31 alcohol-dependent patients without depression and 31 healthy control subjects were included in this study. The resting-state functional connectivity between the amygdala and the whole brain was compared among the three groups. Additionally, we examined the correlation between functional connectivity values in significantly different brain regions and levels of alcohol dependence and depression. RESULTS: The resting-state functional connectivity between the left amygdala and the right caudate nucleus was decreased in alcohol-dependent patients. Additionally, the resting-state functional connectivity of the right amygdala with the right caudate nucleus, right transverse temporal gyrus, right temporal pole: superior temporal gyrus were also decreased. In alcohol-dependent patients with depression, not only was functional connectivity between the above brain regions significantly decreased, but so was functional connectivity between the right amygdala and the left middle temporal gyrus. Also, there was no significant correlation between the resting-state functional connectivity values in statistically significant brain regions and the levels of alcohol dependence and depression. CONCLUSION: The impairment of the functional connectivity of the amygdala with caudate nucleus and partial temporal lobe may be involved in the neural mechanism of alcohol dependence comorbidity depressive disorders.

A Follow-up Study on Coping Strategies and its Association with Relapse Among Alcohol-dependent Patients.

Background: Alcohol Dependence Syndrome is a chronic illness that is relapsing in nature. Past research has shown that coping strategies that are specific to alcohol dependence are useful in preventing long-term relapse. This follow-up study is, therefore, an attempt to understand the coping styles and strategies that are associated with relapse among individuals dependent on alcohol. Methods: We aimed to cross-sectionally assess the severity of alcohol dependence and coping styles of Alcohol dependent individuals. One hundred and twenty-seven consecutive patients who satisfied the International Classification of Diseases Tenth Edition (ICD 10) criteria for alcohol dependence and who were above the age of 18 years were included. This study was conducted in the de-addiction outpatient services of a Tertiary care center in South India between April 2019 and June 2020. Our Institutional Ethical Committee granted the approval for this study. We used a self-designed proforma for collecting the socio-demographic details. The Severity of Alcohol Dependence Questionnaire (SADQ) and Coping Orientation to Problems Experienced Inventory (Brief - COPE) were administered. Patients were followed up for six months. Motivation Enhancement Therapy was given to all our participants during their monthly follow-up visit. Descriptive analysis was performed using mean and standard deviation. We used the student t-test and chi-squared test to understand the differences in the coping strategies between relapsed and non-relapsed persons. Spearman's correlation was used to assess the correlation between the severity of alcohol dependence and coping strategies. A p value of <.05 was taken as significant. Results: Non-relapsed individuals had significantly higher scores on active coping (p = .008), emotional support (p = .044), informational support (p = .017), planning (p < .001), acceptance (p = .030), and humor (p = .001). Relapsed individuals had statistically significant scores on denial (p = .005), substance use (p = .024), and self-blame (p = .012). We found a positive correlation between the severity of alcohol dependence and maladaptive coping strategies (p < .01). Conclusions: Relapsed individuals were found to have significantly higher maladaptive coping strategies. Non-relapsed individuals exhibited greater adaptive coping styles. Maladaptive coping strategies positively correlated with the severity of alcohol dependence.

Potential Molecular Mechanisms of Alcohol Use Disorder with Non-Coding RNAs and Gut Microbiota for the Development of Superior Therapeutic Application.

Many investigations have evaluated the expression of noncoding RNAs (ncRNAs) as well as their related molecular functions and biological machineries in individuals with alcohol dependence. Alcohol dependence may be one of the most prevailing psychological disorders globally, and its pathogenesis is intricate and inadequately comprehended. There is substantial evidence indicating significant links between multiple genetic factors and the development of alcohol dependence. In particular, the critical roles of ncRNAs have been emphasized in the pathology of mental illnesses, probably including alcohol dependence. In the comprehension of the action of ncRNAs and their machineries of modification, furthermore, they have emerged as therapeutic targets for a variety of psychiatric illnesses, including alcohol dependence. It is worth mentioning that the dysregulated expression of ncRNAs has been regularly detected in individuals with alcohol dependence. An in-depth knowledge of the roles of ncRNAs and m6A modification may be valuable for the development of a novel treatment against alcohol dependence. In general, a more profound understanding of the practical roles of ncRNAs might make important contributions to the precise diagnosis and/or actual management of alcohol dependence. Here, in this review, we mostly focused on up-to-date knowledge regarding alterations and/or modifications in the expression of ncRNAs in individuals with alcohol dependence. Then, we present prospects for future research and therapeutic applications with a novel concept of the engram system.

Prevalence of hazardous drinking and suspected alcohol dependence in Japanese primary care settings.

OBJECTIVE: We aimed to assess the prevalence of hazardous drinking and potential alcohol dependence among Japanese primary care patients, and their readiness to change and awareness of others' concerns. METHODS: From July to August 2023, we conducted a multi-site cross-sectional study as a screening survey for participants in a cluster randomized controlled trial. The trial included outpatients aged 20-74 from primary care clinics. Using the Alcohol Use Disorders Identification Test (AUDIT) alongside a self-administered questionnaire, we evaluated the prevalence of hazardous drinking and suspected alcohol dependence, patients' readiness to change, and their awareness of others' concerns. RESULTS: Among the 1388 participants from 18 clinics, 22% (95% confidence interval (CI): 20% to 24%) were identified as engaging in hazardous drinking or suspected of being alcohol dependent. As the AUDIT scores increased, so did their readiness to change. However, only 22% (95%CI: 16% to 28%) of those with scores ranging from 8 to 14 reported that others, including physicians, had expressed concerns about their drinking during the past year. For those with scores of 15 or higher, the figure was 74%. CONCLUSIONS: This study underscores the need for universal or high-risk alcohol screening and brief intervention in Japanese primary care settings.

Pharmacological treatments for alcohol dependence: Evidence on uptake, inequalities and comparative effectiveness from a UK population-based cohort.

INTRODUCTION: We assessed the prevalence of prescribing of certain medications for alcohol dependence and the extent of any inequalities in receiving prescriptions for individuals with such a diagnosis. Further, we compared the effectiveness of two of the most prescribed medications (acamprosate and disulfiram) for alcohol dependence and assessed whether there is inequality in prescribing either of them. METHODS: We used a nationwide dataset on prescriptions and hospitalisations in Scotland, UK (N = 19,748). We calculated the percentage of patients receiving alcohol dependence prescriptions after discharge, both overall and by socio-economic groups. Binary logistic regressions were used to assess the odds of receiving any alcohol-dependence prescription and the comparative odds of receiving acamprosate or disulfiram. Comparative effectiveness in avoiding future alcohol-related hospitalisations (N = 11,239) was assessed using Cox modelling with statistical adjustment for potential confounding. RESULTS: Upto 7% of hospitalised individuals for alcohol use disorder received prescriptions for alcohol dependence after being discharged. Least deprived socio-economic groups had relatively more individuals receiving prescriptions. Inequalities in prescribing for alcohol dependence existed, especially across sex and comorbidities: males had 12% (odds ratio [OR] 0.88, 95% confidence interval [CI] 0.81-0.96) and those with a history of mental health hospitalisations had 10% (OR 0.90, 95% CI 0.82-0.98) lower odds of receiving prescriptions after an alcohol-related hospitalisation. Prescribing disulfiram was superior to prescribing acamprosate in preventing alcohol-related hospitalisations (hazard ratio ranged between 0.60 and 0.81 across analyses). Disulfiram was relatively less likely prescribed to those from more deprived areas. DISCUSSION AND CONCLUSIONS: Inequalities in prescribing for alcohol dependence exists in Scotland with lower prescribing to men and disulfiram prescribed more to those from least deprived areas.

A qualitative exploration of the experiences of transdermal alcohol sensor devices amongst people in receipt of treatment for alcohol use disorder.

Introduction: Transdermal alcohol sensors (TAS) have the potential to be used as a clinical tool in alcohol treatment, but there is limited research with individuals with alcohol dependence using TAS. Our study is a qualitative evaluation of the views of people attending alcohol treatment and their experiences of wearing the BACtrack Skyn, within alcohol services in South London. Methods: Participants with alcohol dependence wore a BACtrack Skyn TAS for one week and met with the researcher every two days, for a total of four meetings (for example: Monday, Wednesday, Friday, and Monday). In the final meeting, a post-wear survey (on their physical, social and comfort experience of the TAS) and semi-structured interview were completed. The Technology Acceptance Model (TAM) informed the topic guide and data analysis. Results: Adults (N = 16) receiving alcohol treatment were recruited. Three core topics guided analysis: perceived usefulness, perceived ease of use and attitudes towards use. Participants found the TAS easy to wear and felt positive about its appearance and comfort. The only challenges reported were side effects, mostly skin irritation. The main two perceived uses were 1) TAS working as a drinking deterrent and 2) reducing daily breathalyser visits during detox. Conclusion: Findings support the use of TAS amongst alcohol service users. Wearing the TAS for one week was acceptable and feasible for objective alcohol concentration measurement. Participants reported high perceived ease of use and usefulness of the Skyn in the context of alcohol treatment. These results are encouraging for the use of TAS in clinical settings.
