A Novel Scale of Lifestyle Physical Activity: Measure Description and Intervention Responsiveness

Lifestyle physical activity (LPA) interventions emphasize small bouts of movement that can be flexibly integrated into one’s everyday routine. Despite research illustrating benefits for LPA on health outcomes, few LPA interventions and measurement tools have been developed and tested. The purpose of this study was to present a novel LPA self-report scale, including its content, scoring, and internal consistency reliability, and summarize its intervention responsiveness. The LPA scale was administered in a pilot randomized controlled trial that tested a 12-week LPA + Fitbit intervention against a health education (HE) control (matched to LPA + Fitbit on contact time) in a sample of 50 women with depression in alcohol treatment. The LPA scale includes 22 items covering five domains relevant to LPA. Results demonstrated good internal consistency reliability for the total score (ω = 0.84) but poor-to-acceptable internal consistency reliability for the domain scores (ω range: 0.43-0.80). Participants randomized to the LPA + Fitbit intervention had significantly greater improvements in the LPA total score and two domain scores compared to HE participants. Overall, results demonstrate good internal consistency reliability and intervention responsiveness of the LPA scale total score. A larger, more comprehensive psychometric evaluation is needed for validation of this scale.

Effects of Kalimeris indica on alcohol-induced liver injury through storing Nrf2/HO-1 pathway and gut microbiota

BackgroundKalimeris indica (L.) Sch. Bip., (K. indica) is a plant classified under the genus Kalimeris within the Asteraceae family. The herb of K. indica has been historically utilized as a traditional medicine. The consumption of excessive amounts of alcohol represents a lifestyle choice that can induce tissue damage and contribute to the development of various health conditions.MethodThe HPLC-MS method was used to reveal the chemical composition of K. indica extract. HepG2 cells were used to test the in vitro oxidative stress. C57BL/6 mice were used to construct the in vivo alcohol-induced liver injury. H/E staining and serum ALT and AST levels were tested to assess the in vivo protective effect of ML (50 and 200 mg/kg). GSH, SOD, and CAT levels along with byproduct MDA levels were used to evaluate the in vivo oxidative stress. Immunohistochemical experiments were used to examine the in vivo Nrf2 and HO-1 levels. 16S rRNA gene-based profiling method was used to test the alteration in gut microbiota.Results16 compounds were identified from K. indica extract. K. indica treatment reduced oxidative stress in HepG2 cells treated with 5% alcohol. H/E staining results showed that K. indica (50 and 200 mg/kg) alleviated liver injury caused by alcohol administration, eliciting a similar protective effect to the positive drug silymarin. Serum ALT and AST examination gave a consistent result, showing that ML could restore serum ALT and AST levels in mice treated with alcohol. Furthermore, K. indica could also restore GSH, SOD, CAT, and MDA levels in alcohol-treated mice, showing a potent effect on oxidative stress alleviation. Immunohistochemical experiments indicated that K. indica showed the liver protective effect through Nrf2/HO-1 pathway. 16S rRNA gene-based profiling revealed that alcohol treatment caused the alteration in gut microbiota, while K. indica treatment could result in a significantly richer variety of microbial communities compared to the alcohol group.ConclusionK. indica (ML) has a protective effect on liver injury caused by alcohol administration. The Nrf2/HO-1 pathway and gut microbiota regulation were involved in the ML-induced liver protection. All the results indicate that K. indica has a potential in the treatment of alcohol-induced liver injury.

Next-generation biomarkers for alcohol consumption and alcohol use disorder diagnosis, prognosis, and treatment: Acritical review.

This critical review summarizes the current state of omics-based biomarkers in the alcohol research field. We first provide definitions and background information on alcohol and alcohol use disorder (AUD), biomarkers, and "omic" technologies. We next summarize using (1) genetic information as risk/prognostic biomarkers for the onset of alcohol-related problems and the progression from regular drinking to problematic drinking (including AUD), (2) epigenetic information as diagnostic biomarkers for AUD and risk biomarkers for alcohol consumption, (3) transcriptomic information as diagnostic biomarkers for AUD, risk biomarkers for alcohol consumption, and (4) metabolomic information as diagnostic biomarkers for AUD, risk biomarkers for alcohol consumption, and predictive biomarkers for response to acamprosate in subjects with AUD. In the final section, the clinical implications of the findings are discussed, and recommendations are made for future research.

Improving screening, brief intervention and referral to treatment for unhealthy alcohol use in diverse, low-resourced primary care clinics.

Implementation of screening brief intervention and referral to treatment (SBIRT) and medication-assisted treatment for alcohol use disorder (MAUD) remains low in primary care. ANTECEDENT (Partnerships to Enhance Alcohol Screening, Treatment, and Intervention) was a practice-facilitator led implementation study to increase SBIRT and MAUD use in diverse primary care clinics. From November 2019 - April 2023, we conducted a convergent parallel mixed methods evaluation. Participants were small and medium-sized primary care clinics in the Northwestern U.S. Clinics received foundational support (i.e., baseline/exit assessment, access to SBIRT Oregon website) and the option for supplemental implementation support (e.g., practice facilitation, expert consultation) over the 15-month intervention to improve SBIRT and MAUD. Qualitative and quantitative data regarding clinic characteristics, implementation strategies, and SBIRT/MAUD outcomes were collected through practice facilitator interviews, periodic reflections and clinic contact logs, interviews, pre-post surveys, and electronic health record (EHR) queries. Quantitative analyses included descriptive statistics, logistic regression, and the Wilcoxon sign-ranked test. Qualitative analysis took an immersion crystallization approach. Data were reviewed in a matrix to evaluate intervention adoption, implementation, and effectiveness. We recruited 75 unique clinics; 66 participated and 48 (73%) completed the study. Eight participating clinics chose to receive foundational support only (12%) while 58 chose to engage in supplemental support (88%) activities. Clinics that received supplemental support and completed the intervention (n = 42) engaged in practice facilitation (Mean: 293min, range: 75-550min); data review (38%), HIT support (31%), expert consultation (19%), and peer-to-peer learning (5%). Pre- and post-intervention assessments showed significant improvement in self-reported SBIRT process outcomes. Performance data improved among the subset of completing clinics able to produce data (n = 17). Clinics described positive experiences with ANTECEDENT support and highlighted remaining barriers to SBIRT and MAUD implementation. Participating clinics engaged in a diverse range of supportive activities. A flexible approach using practice facilitation and implementation support could be helpful for low-resourced primary care clinics in improving SBIRT and MAUD for unhealthy alcohol use.

Factors Associated With Motivation to Reduce Alcohol Use Among Patients With Chronic Liver Disease.

Alcohol use is prevalent among hepatology clinic patients with chronic liver disease (CLD). We explored factors associated with the importance and confidence dimensions of motivation to reduce drinking. Participants (N = 121) with unhealthy alcohol use (i.e., over NIH guidelines) receiving care in hepatology clinics from a safety-net hospital (SN, N = 54) and two Veterans Affairs Healthcare Systems (VA, N = 67) were enrolled in an alcohol intervention trial from March 2022 through October 2023. Baseline assessments included Generalised Anxiety Disorder (GAD-7), Patient Health Questionnaire (PHQ-8), Alcohol Use Disorders Identification Test (AUDIT), COVID-19 stress; and measures of importance and confidence to decrease alcohol use (readiness rulers, scales of 1-10). Liver disease aetiology and severity were extracted from electronic health records. We performed multivariable linear regression models with forward selection to assess pre-specified variables' associations with importance and confidence. The sample was 84% male, 40% Latino, 31% White, 18% Black and 11% other races; median age was 61 years. Median (Q1-Q3) AUDIT score was 16 (12-24), importance was 9 (6-10) and confidence was 8 (5-9). On multivariable analysis, VA site (vs. SN) participants had a 0.97-point lower importance score (p = 0.02); higher symptoms of depression (PHQ-8 score ≥ 10 vs. < 10) and AUDIT scores (for each point increase) were associated with higher importance score (estimates 1.2 and 0.08, p < 0.05, respectively). Liver disease aetiology and severity were not significantly associated with outcomes. Depression, alcohol problem severity and treatment site may influence motivation to reduce alcohol use and could inform future hepatology-based interventions.

Exploring the feasibility of Recovery Management Checkups for Primary Care in a Federally Qualified Health Center

IntroductionPrimary care settings present an opportunity for alcohol and substance use disorder (A/SUD) screening and treatment referral. However, there are recognized deficiencies in widely used treatment referral approaches, including acute care connections, vs. those that can support longer-term recovery. Recovery Management Checkups for Primary Care (RMC-PC) is an intervention with an evidence base for improving treatment referral and subsequent recovery for primary care patients; however, the intervention has never been fully implemented outside of a research context. We conducted a feasibility study to inform a future hybrid study of RMC-PC that will test the implementation and effectiveness of the intervention in primary care practice.MethodWe used a convergent mixed method design. The study’s setting was a Federally Qualified Health Center (FQHC) located in a large midwestern city. RMC-PC linkage services were administered by one of two treatment linkage managers: an FQHC linkage manager (F-LM) and a research staff linkage manager (R-LM). Quantitative data included (a) rates of positive A/SUD screening among a group of FQHC patients and (b) linkage manager service data (e.g., rate of successful meeting completion and days to completing of key events). Qualitative data included (c) an assessment of linkage manager’s motivational interviewing performance and (d) a focus group with FQHC staff focused on their perspectives on RMC-PC implementation determinants. Quantitative data were summarized using descriptive statistics, and linkage manager performance was compared. Qualitative data were analyzed using a hybrid deductive-inductive process.ResultsFifty percent of patients screened met moderate-high A/SUD risk. Eleven of 16 recruited patients completed at least one linkage manager meeting, with 63% completing both meetings. The F-LM delivered RMC-PC services alongside other duties successfully; however, three primary barriers to FQHC implementation were identified (difficulties applying motivational interviewing, incompatibilities of screening with FQHC technology and workflow, and lack of billing mechanism to support services).ConclusionRMC-PC is feasible for FQHC staff to deliver, though issues identified must be considered to ensure successful and sustainable implementation. Knowledge gained will inform a packaged implementation strategy that will be used in a future hybrid trial.

Anticancer Effects of New Disulfiram Analogs.

Disulfiram (DSF), an irreversible aldehyde dehydrogenase 2 (ALDH2) inhibitor, is an U.S. Food and Drug Administration (FDA)-approved drug for the treatment of chronic alcoholism. Recent studies have reported an interesting antitumor activity of DSF against a wide range of human malignancies, while a growing number of ongoing and completed clinical trials have provided evidence supporting the repurposing of DSF as an anticancer treatment. Nevertheless, despite its current clinical indications and potential future therapeutic applications for treating various diseases, DSF is associated with serious side effects attributed to the inhibition of ALDH2. We have recently synthesized DSF analogs (2a-v) with limited inhibition of ALDH2. Here, we report the anticancer activity of these molecules by highlighting their effects on cell signaling in Jurkat cells. DSF and two DSF analogs, 2g and 2r, all stimulated apoptotic signaling pathways, although the 2g analog activated more apoptosis-related genes and induced higher levels of apoptosis in vitro. Differential gene expression data suggested that compounds 2g and 2r specifically reprogram target cells to downregulate pathways related to cell growth and division, while upregulating pathways related to apoptosis or differentiation. Interestingly, both compounds 2g and 2r had more differentially expressed genes related to DNA damage pathways (including those related to apoptosis) when compared to DSF, which may offer insights into their mechanisms of action.

Long-term effectiveness of SBIRT by outreach visits on subsequent alcohol treatment utilization among inpatients from general hospital: a 36-months follow-up

Aim To investigate the long-term effect of Screening, Brief Intervention, and Referral to Treatment (SBIRT) on alcohol treatment utilization among general hospital inpatients. Methods This 36-month follow-up of a randomized controlled trial included general hospital inpatients who were screened using the Alcohol Use Disorder Identification Test (AUDIT). Patients with an AUDIT score of 8+ were included. Patients were randomized to either SBIRT (Relay) or treatment as-usual (TAU). Outcome was attendance at a specialized outpatient treatment institution or prescription of pharmacological alcohol treatment in general practice. Using the Danish Civil Registration System, patients were followed in the Danish National Patient Registry, Danish National Alcohol Treatment Register, and the Danish National Prescription Registry. Data was collected up to 36 months after discharge. Results The study population consisted of 258 patients in the Relay group and 303 patients in the TAU group. In the Relay group, 36 (14.0%) patients received treatment versus 23 (7.6%) in the TAU group. Patients in the Relay group had higher odds for receiving treatment compared to the TAU group (OR: 1.97, 95% CI: 1.1–3.4, p = 0.01). Significantly more patients in the Relay group scored 16+ on the AUDIT and had already tried to change their alcohol consumption (both p < 0.01). Adjusted for potential confounders, the effect of the Relay intervention was reduced (OR: 1.37, 95%CI: 0.7–2.5, p = 0.31). Conclusions This study did not find evidence that SBIRT is better than TAU at sustaining significant long-term alcohol treatment utilization after discharge among inpatients from general hospital.

Daily cigarette smoking among inpatients for substance use disorders in France, 2010-2020: Commonalities and specificities across substances.

This study aims to estimate the prevalence and factors associated with cigarette smoking among patients in treatment for substance use disorders (SUD) in France. We analyze a nation-wide dataset retrieving information on patients entering treatment for alcohol, opioid and stimulant use disorders between 2010 and 2020. We conduct multilevel Poisson regressions to determine the main factors associated with daily cigarette smoking among all patients who entered treatment for alcohol (n=607122), opioid (n=283381) or stimulant (n=57189) use disorders, and zero-truncated negative-binomial regressions to predict the average number of cigarettes per day. Daily cigarette smoking remains a widespread behavior among patients with SUD (overall prevalence: 72.2%, 95% CI: 72.1-72.3), with lower prevalence of daily cigarette smoking among patients treated for alcohol use disorders (69.9%, 95% CI: 69.8-70.0), and higher for patients treated for opioid (78.8%, 95% CI: 78.6-79.0) or stimulant use disorders (75.8%, 95% CI: 75.4-76.2). There was an overall increase in daily cigarette smoking over time (69.9%, 95% CI: 69.8-70.0 in 2010 vs 76.8%, 95% CI: 76.5-76.9 in 2020); however, the average number of cigarettes per day decreased (17.8 per day, 95% CI: 17.7-17.9 in 2010 vs 16.3 per day, 95% CI: 16.2-16.4 in 2020). The higher the education level, the fewer number of cigarettes per day; conversely, the higher the occupational status, the higher the number of cigarettes. The high prevalence of smoking among patients treated for SUD in France departs from the decreasing trend observed in the general population and remains a source of concern. It is necessary to implement tailored prevention strategies that target specific patient subgroups and increase staff awareness.

Curcumol ameliorates alcohol and high-fat diet-induced fatty liver disease via modulation of the Ceruloplasmin/iron overload/mtDNA signaling pathway.

Fatty liver disease (FLD), a chronic liver disease characterized by excessive lipid deposition, is affecting more and more people worldwide owing to the increasing global incidence of obesity and heavy alcohol consumption. However, there is still no effective strategy for prevention or treatment of alcohol and high-fat diet (HFD)-induced FLD. The purpose of this study was to investigate the effect of curcumol on alcohol and HFD-induced FLD and the underlying molecular mechanisms. The results showed that curcumol ameliorated alcohol and HFD-induced hepatocyte injury in vivo and in vitro, and the mechanism might be related to its up-regulation of ceruloplasmin and subsequent alleviation of iron overload. Moreover, curcumol inhibited alcohol and HFD-induced mitochondrial damage and mtDNA release in hepatocytes by modulating iron overload. Furthermore, curcumol's inhibition of mtDNA release could suppress the activation of cGAS-STING and subsequent inflammation, and this phenomenon could be reversed by cGAS overexpression. Notably, alcohol and HFD-induced mtDNA release from hepatocytes contributed to HSC activation and this effect could be weakened by curcumol. In conclusion, these findings elucidated that curcumol ameliorated alcohol and HFD-induced FLD via modulating ceruloplasmin/iron overload/mtDNA signaling pathway, which lead to the inhibition of inflammation and HSCs activation.

미술치료 전공 학부생의 임상실습, 수퍼비전, 학부과정 경험에 대한 질적 연구

Objectives The purpose of this study is to explore through qualitative research the experiences of undergraduate students majoring in art therapy in clinical practice, supervision, and undergraduate courses, and to analyze the intrinsic meaning of these experiences. Methods Data were collected through two in-depth interviews with six undergraduate students majoring in alco-hol treatment. The interviews used a semi-structured questionnaire to encourage undergraduate students to talk freely about their experiences in clinical practice, supervision, and undergraduate courses. The collected data were analyzed using open coding according to qualitative research methodology, and themes were derived inductively. Through this, the main themes and subcategories experienced by the participants were identified and the research results were derived. Results As a result of the analysis, 6 main areas, 14 categories, and 37 subcategories were derived. In clinical practice, external factors such as conditions of the practice institution, workload, communication between thera-pists, and changes in clients, and internal factors such as self-criticism, tension while performing roles, and sense of accomplishment after practice were identified. The supervision experience consisted of process aspects such as close supervision and shared experiences with colleagues, as well as academic and emotional support from the supervisor. During the bachelor's course, self-exploration, anxiety and burden about art work, and interaction with classmates served as factors that promoted improved future vision and psychological growth. Conclusions These findings provide significant implications for establishing criteria for selecting clinical practice institutions, improving supervision education, and enhancing the role of school education in undergraduate pro-grams aimed at training art therapists.

Interest in the Use of Herbal Supplements to Close the Treatment Gap for Hazardous Alcohol Use Among Men Who Have Sex With Men: Secondary Analysis of a Cross-Sectional Study.

Hazardous alcohol consumption is highly prevalent for men who have sex with men (MSM). The 4 treatments currently approved by the Food and Drug Administration for alcohol use are reaching an alarmingly low percentage of people who would benefit from a reduction in their alcohol use. There is increasing interest in alternative methods of treatment, such as herbal supplements, to address hazardous drinking. However, research on the acceptability of alternative pharmacotherapies among MSM remains limited. We examined the prevalence and correlates of expressing interest in using herbal supplements for alcohol treatment among MSM with hazardous alcohol consumption. We conducted a secondary data analysis from a cross-sectional study of MSM who use alcohol, conducted from March 2015 to July 2017 in San Francisco, California, to assess the overall prevalence of interest in using herbal supplements to help reduce alcohol consumption. Associations between expressing interest in herbal supplements and demographic, social, and clinical characteristics were examined using bivariate and multivariable logistic regression models. One-third (66/200, 33%) of the participants expressed interest in an herbal supplement for reducing alcohol consumption. In the multivariable analyses, weekly binge drinking (adjusted odds ratio [aOR] 2.85, 95% CI 1.17-6.93), interest in abstaining from alcohol use (aOR 5.04, 95% CI 1.46-17.40), higher severity of alcohol dependence score (aOR 1.22, 95% CI 1.04-1.41), and interest in naltrexone (aOR 3.22, 95% CI 2.12-4.91) were independently associated with higher odds of being interested in using an herbal supplement to reduce alcohol consumption, adjusting for age, race or ethnicity, and education. We found that MSM who have hazardous drinking habits, more severe alcohol dependence, and interest in pharmacotherapy were more likely to express interest in using an herbal supplement for reducing alcohol consumption. To our knowledge, this is the first study that has evaluated correlates of interest in herbal supplements for alcohol use among MSM. As researchers implement novel alcohol treatment studies, they should focus on recruitment efforts among MSM with a motivation to reduce their alcohol use patterns.

Psychometric Properties of the Credibility/Expectancy Questionnaire in Individuals with Opioid Use Disorder

ABSTRACT Credibility and expectancy are important aspects of therapy/treatment processes. We aimed to perform cross-cultural validation and examine the psychometric properties of the Credibility/Expectancy Questionnaire (CEQ). Ninety-one patients with opioid use disorder from Tobacco, Alcohol, and Drug Addiction Treatment Program were included in the study. Sociodemographic data form, CEQ, Beck Depression Inventory (BDI), State and Trait Anxiety Inventory (STAI), and Attitudes Toward Seeking Psychological Professional Help Scale-Short Form (ATSPPHS-SF) were filled out by participants. Confirmatory factor analyses showed that CEQ has two factors in our sample, similar to the original version. Reliability analyses showed that CEQ has a high internal consistency and test-retest reliability. Regarding convergent validity results, CEQ was correlated with ATSPPHS-SF. No significant correlation was found between CEQ and BDI and STAI regarding discriminant validity results. In conclusion, the Turkish version of CEQ is a valid, reliable scale and could be used in patients with opioid use disorder. In patients with opioid use disorder, we contributed to the addiction literature by adapting a short and effective survey that measures trust and expectation.

Altered Expression of Neuroplasticity-Related Genes in Alcohol Addiction and Treatment.

Alcohol use disorder's complexity arises from genetic and environmental factors, with alcohol metabolism genes and neurotransmitter pathways being critical. This study aims to analyze synaptic plasticity gene expression changes in individuals with AUD in order to study their contribution to AUD development and to identify potential biomarkers of treatment response. RNA was extracted from whole peripheral blood (20 patients, 10 healthy controls), before and after treatment (Qiagen AllPrep RNA/DNA Mini Kit), and the gene expression of 84 genes related to neuroplasticity was studied using the RT2 Profiler for Human Synaptic Plasticity RT-PCR Array (PAHS-126ZA, Qiagen), comparing AUD patients to control and responders to non-responders. The potential prognostic/predictive biomarkers were searched using machine learning models. A total of 35 dysregulated genes were found in AUD patients. EPHB2, EGR, and AKT1 were increased, while TIMP1, NCAM1, and GRM2 were decreased. Responders showed distinct gene expression profiles at baseline. After treatment, the expression of 57 genes was normalized, while NCAM1, GRM2, and BDNF showed the most significant recovery. EGR4, INHBA, and NCAM1 emerged as potential biomarkers to predict treatment success. These results indicate that gene profiles in peripheral blood can serve as prognostic markers for the prognosis and treatment of AUD, although further validation is required.

Effect of Benzyl Alcohol on Main Defense System Components of Galleria mellonella (Lepidoptera).

Benzyl alcohol (E1519) is an aromatic alcohol used in the pharmaceutical and food industry. It is used to protect food products against microorganisms during storage, as a flavoring in the production of chocolate and confectionery products, as an important ingredient in fragrance, and as a preservative in medical products. However, little is known of its effect on insects. The main aim of this study was to determine the influence of benzyl alcohol on the defense systems of the wax moth Galleria mellonella, i.e., its cuticular lipid composition and critical elements of its immune system. A gas chromatography/mass spectrometry (GC/MS) analysis found benzyl alcohol treatment to elicit significant quantitative and qualitative differences in cuticular free fatty acid (FFA) profiles. Our findings indicate that benzyl alcohol treatment increased the levels of HSP70 and HSP90 and decreased those of HSF1, histamine, and cysteinyl leukotriene. Benzyl alcohol application also increased dismutase level in the hemolymph and lowered those of catalase and 8-OHdG. The treatment also had negative effects on G. mellonella hemocytes and a Sf9 cell line in vitro: 48-h treatment resulted in morphological changes, with the remaining cells being clearly spindle-shaped with numerous granules. The high insecticidal activity of compound and its lack of toxicity towards vertebrates suggest it could be an effective insecticide.

How to motivate adolescents who are afraid of treatment?

Motivation has long been considered key to sending substance use disorder (SUD) patients in the direction of recovery. But how do you motivate an adolescent, to whom motivational approaches may feel like a call to battle — or even worse, an excuse for running away? Lauren Sbarbaro, Ph.D., a psychologist licensed in alcohol and drug treatment who trained at Hazelden, shared some insights with attendees at the Cape Cod Symposium on Addictive Disorders (CCSAD) in Hyannis, Massachusetts last week.

Routine outcome monitoring and feedback in alcohol and other drug treatment: A qualitative study of client perspectives on implementation.

Routine outcome monitoring (ROM) and feedback is an evidence-supported strategy for evaluating alcohol and other drug (AOD) treatment outcomes. However, the implementation of ROM and feedback into AOD services remains a significant challenge. Research aimed at understanding client perspectives on ROM and feedback is needed to facilitate successful implementation. This study examined experiences with and perceptions of ROM and feedback in a sample of clients receiving AOD treatment. Interviews and online surveys were conducted with N = 26 people (13 male; Mage = 36.12 years, SD = 10.29) enrolled in an AOD treatment program in Australia. Data analysis of the transcripts was guided by thematic analysis, while descriptive statistics were used to analyse quantitative survey data. Four major themes were identified in the qualitative data: (i) ROM and feedback is valuable to AOD treatment; (ii) clear and concise outcome measures with an integrated feedback loop are vital to reliable ROM; (iii) desire for visual and verbal feedback that highlights progress; and (iv) ROM and feedback can be emotionally challenging. Participants valued ROM when it was clearly integrated within AOD treatment and they received feedback on their responses. Potential facilitators to implementing and improving the provision of ROM and feedback in AOD treatment include: (i) a clear, treatment-based rationale to foster client buy-in for ROM and maximise AOD treatment benefit; (ii) brief outcome measure surveys; and (iii) graphical visualisations of ROM feedback.

Development of an accelerometer-based wearable sensor approach for alcohol consumption detection.

Alcohol is a commonly used substance associated with significant public health consequences. Treatment is often stigmatized and limited with regard to both access and affordability, demonstrating the need for innovations in alcohol treatment. Accelerometer sensors can detect drinking without user input and are widely incorporated into wearable devices, increasing accessibility and affordability. We compared a distributional and random forest classification approach to detect and evaluate sensor-based drinking data. Data were collected at a local state fair (n = 194), where participants drank water at specified intervals interspersed with confounding behaviors (e.g., touching nose, rubbing forehead, or yawning) while wearing an Android-based smartwatch for 10 min. Participants were randomized to receive one of three drinking container shapes: pint, martini, or wine. The random forest model achieved an overall testing accuracy of 93% (sensitivity = 0.32; specificity = 0.99; positive predictive value = 0.74). The distributional algorithm achieved an overall accuracy of 95% (sensitivity = 0.76; specificity = 0.97; positive predictive value = 0.72). The distributional algorithm had a significantly greater accuracy (t(193) = 7.73, p < 0.001, d = 0.56) and sensitivity (t(193) = 24.5, p < 0.001, d = 1.76). Equivalency testing demonstrated significant equivalency to the ground truth for sip duration (tlower(193) = 16.92, p < 0.001; tupper(193) = -9.85, p < 0.001) and between-sip interval (tlower(193) = 1.72, p = 0.044; thigher(193) = -3.96, p < 0.001). However, the random forest did not have significant equivalency to the ground truth for between-sip interval (tlower(193) = 1.98, p = 0.025; thigher(193) = 0.160, p = 0.564). Overall, the results indicated that consumer-grade smartwatches can be utilized to detect and measure alcohol use behavior using machine learning and distributional algorithms. This work provides the methodological foundation for future research to analyze the behavioral pharmacology of alcohol use and develop accessible just-in-time clinical interventions.

Protective mechanisms of Hovenia dulcis Thunb extracts on acute alcoholism and liver injury

As a traditional Chinese medicine for anti-alcoholism, Hovenia dulcis Thunb (HDT) is widely used in the treatment of alcoholism and alcohol-related liver diseases. However, the scientific evidence of its mechanism has not been clearly established. In this study, a mouse model of acute alcoholism was established to explore the protective mechanisms of three kinds of HDT extracts on acute alcoholism and liver injury from the perspectives of behavioral indicators, serum and liver biochemical indicators, alcohol metabolic enzyme activity, intestinal flora, and liver metabolomics. The results showed that the extracts of HDT shortened the time of sobering up, significantly increased the activity of alcohol metabolic enzymes and antioxidant capacity, promoted ethanol metabolism, and had a certain preventive effect on alcoholic liver injury while preventing adverse reactions caused by alcohol. Notably, HDT water extract (HDTs) demonstrated superior anti-alcohol and liver protective properties compared to polysaccharide and polyphenol extracts of HDTs. It may be through the regulation of intestinal flora imbalance, specifically Muribaculaceae and Dubosiella to modulate biosynthetic pathways of phenylalanine, tyrosine, and tryptophan, ultimately mitigating oxidative stress caused by ethanol consumption. This suggests that HDTs may have potential in preventing acute alcoholism and liver injury.

British South Asian and Muslim Community's Perceptions and Experiences of Addiction and Traditional Drug and Alcohol Treatment Services.

Within traditional drug and alcohol (D&A) treatment services, the majority of those accessing support are of white ethnicity, with only a small percentage of people from the British South Asian (BSA) and Muslim community engaging in treatment services. This paper aims to explore perceived barriers to accessing traditional D&A services within the British South Asian and Muslim communities, based on qualitative data from interviews with family members and a practitioner. Qualitative data were obtained via 11 semi-structured interviews involving a practitioner (n = 1), and family and friends (n = 10) of those with historic and current D&A use in the community. Reflexive thematic analysis revealed four themes: (1) awareness of drug and alcohol use in the community, (2) drug and alcohol use as a taboo topic and the impact of admitting use, (3) knowledge of services for treatment, (4) how to increase awareness and accessibility of treatment. There was an increasing awareness of D&A use in the BSA and Muslim community. Despite this, limited conversations and misconceptions around D&A use and recovery led to those using D&A and their family members feeling stigmatised within their community and unable to seek support. This paper concludes by recommending increased communication between the BSA and Muslim communities and D&A treatment services to ensure accessibility of treatment by improving cultural competency.
