Abstract
BACKGROUND Alcohol use disorder (AUD) is a major public health issue, posing harmful consequences for individuals and society. Recent advances in addiction research have highlighted the therapeutic potential of ketamine-assisted therapy for AUD. However, the exact mechanisms underlying its effectiveness remain unknown. AIMS This double-blind, pilot study aimed to investigate esketamine combined with mindfulness-based intervention (MBI) to examine whether esketamine enhances engagement in MBI for individuals with alcohol misuse problems and whether enhanced engagement has any impact on alcohol-related outcomes. METHODS In all, 28 individuals with alcohol problems were randomly assigned to receive sublingual esketamine hydrochloride (AWKN002: 115.1 mg) or vitamin C (placebo) in an oral thin film and took part in 2 weeks of daily MBI. Participants were assessed on various self-report measures, including mindfulness, engagement in MBI (physical and psychological), alcohol cravings and consumption. RESULTS Esketamine enhanced psychological engagement with a daily MBI, compared to placebo, and led to transient decreases in alcohol cravings. Esketamine also resulted in significantly greater mystical experiences and dissociative states compared to placebo. CONCLUSIONS The findings suggest that esketamine may improve treatment outcomes when combined with mindfulness-based therapies through its ability to increase engagement with meditative practice.

Presenting Pattern and Psychiatric Comorbidities in Rural versus Urban Substance Dependent Patients: A Hospital-Based Cross-Sectional Study. Indian J Community Med 2023; 48:666-675. [PMID: 37970168 PMCID: PMC10637592 DOI: 10.4103/ijcm.ijcm_618_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Accepted: 06/27/2023] [Indexed: 11/17/2023] Open
Abstract
Background "Locality" is a significant factor in substance initiation, maintenance, and relapse. The pattern of substance dependence among rural and urban populations varies across studies and is scarcely studied, warranting further research. To compare presenting patterns (sociodemographic and drug-related variables), reasons for substance use, and psychiatric comorbidities (prevalence, type, and severity) between rural and urban substance-dependent groups. Materials and Methods This study was a cross-sectional analytical study in a government de-addiction center, including rural and urban patient groups aged 18-65. International Classification of Diseases, Tenth Revision (ICD-10) criteria, and severity of dependence scale were used for diagnosing substance dependence. After detoxification, psychiatric comorbidity was assessed using brief psychiatric rating scale, Young's mania rating scale, and patient health questionnaire - somatic, anxiety, and depression symptoms scale. Post-analysis was performed to assess socioeconomic variables and access to de-addiction services. Results The final sample was 500 (250 rural and 250 urban). The post-analysis sample size was 386 (211 rural and 175 urban). The mean age was 38.2 ± 12.4 years, mostly males (n = 495, 99%). Substance frequency was opioids (92%)> benzodiazepines (24.8%) > alcohol (22%) > cannabis (1.6%) for rural and opioids (91.2%) > alcohol (29.6%) > benzodiazepines (14.8%) > cannabis (2%) for urban patients. More than half of patients had comorbid nicotine dependence. Rural patients were more benzodiazepine dependent (P = 0.007), and urban were more opioid + alcohol dependent (P = 0.001). Rural patients had higher age (P = 0.012), less education (P < 0.001), positive family history of substance (P = 0.028), daily wagers, and farmers (P < 0.001) than urban patients who were younger, students (P = 0.002), businessmen and government employed (P < 0.001). Urban patients expended more on drugs (P < 0.001), had higher treatment attempts (P = 0.008), and had better availability and accessibility of de-addiction services (P < 0.001). More rural users initiated substances to "enhance performance," whereas urban ones initiated for "stress relief/novelty" (P < 0.001). For treatment seeking, "External pressure" was a more common reason in urban patients (P < 0.001), who also had more psychiatric comorbidities (P = 0.026). Conclusion Significant pattern differences exist between rural and urban substance dependents, warranting emphasis on locality-specific factors for appropriate intervention.

Fleury MJ, Cao Z, Grenier G, Huỳnh C. Predictors of dropout from treatment among patients using specialized addiction treatment centers. JOURNAL OF SUBSTANCE USE AND ADDICTION TREATMENT 2023; 150:209062. [PMID: 37150400 DOI: 10.1016/j.josat.2023.209062] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Revised: 03/06/2023] [Accepted: 05/01/2023] [Indexed: 05/09/2023]
Abstract
OBJECTIVES This study investigated the use of outpatient care, and sociodemographic and clinical characteristics of patients with substance-related disorders (SRD) to predict treatment dropout from specialized addiction treatment centers. The study also explored risks of adverse outcomes, frequent emergency department (ED) use (3+ visits/year), and death, associated with treatment dropout within the subsequent 12 months. METHODS The study examined a cohort of 16,179 patients who completed their last treatment episode for SRD between 2012 and 13 and 2014-15 (financial years: April 1 to March 31) in 14 specialized addiction treatment centers using Quebec (Canada) health administrative databases. We used multivariable logistic regressions to measure risk of treatment dropout (1996-96 to 2014-15), while we used survival analysis controlling for sex and age to assess the odds of frequent ED use and death in 2015-16. RESULTS Of the 55 % of patients reporting dropout from SRD treatment over the 3-year period, 17 % were frequent ED users, and 1 % died in the subsequent 12 months. Patients residing in the most socially deprived areas, having polysubstance-related disorders or personality disorders, and having previously dropped out from specialized addiction treatment centers had increased odds of current treatment dropout. Older patients, those with a history of homelessness, past SRD treatment, or more concurrent outpatient care outside specialized addiction treatment centers had decreased odds of treatment dropout. Patients who dropped out were subsequently at higher risk of frequent ED use and death. CONCLUSIONS This study highlighted that patients with more severe problems and previous dropout may need more sustained and adequate help to prevent subsequent treatment dropout. Specialized addiction treatment centers may consider enhancing their follow-up care of patients over a longer duration and better integrating their treatment with other outpatient care resources to meet the multiple needs of the more vulnerable patients using their services.

Abstract
Background Hepatitis C virus (HCV) infection is commonly comorbid with opioid dependence (OD). We wanted to compare the neurocognitive functions of OD subjects with or without HCV [HCV (+), HCV (-)] and healthy controls (HC). Methods We recruited 40 adult subjects (age 18-55 years) in each group. HCV(+) group had a detectable viral load. Subjects with HIV or hepatitis B infection, head injury, epilepsy, or comorbid mental illness were excluded. We administered Standard Progressive Matrices (SPM), Wisconsin Card Sorting Test, Iowa Gambling Task (IGT), trail-making tests A and B, and verbal and visual N-back tests (NBT) one week after opioid abstinence. The group differences in cognitive performance were adjusted for age and years of education. Effect size (ES) is expressed as Cohen's D. Results The HCV(+) and HCV(-) groups did not differ in potential effect modifiers (age and years of education) or confounders (age of opioid initiation, duration of use, dependence severity, tobacco use, and cannabis use) of neuropsychological functioning. HCV(+) showed significantly poorer performance than HCV(-) in SPM (P = 0.006; ES = 0.72). Both HCV(+) and HCV(-) performed worse than controls in IGT(P < 0.001; ES = 0.8) and visual NBT[P < 0.01 and ES > 1 for total errors]; HCV(+) had a larger ES of group difference than HCV(-). HCV(+) had higher error scores in verbal NBT than control. Conclusion HCV(+) has poorer general intellectual ability and reasoning than HCV(-) persons and controls. Chronic HCV infection causes a higher magnitude of dysfunction in decision-making and visual working memory in opioid-dependent individuals.

Abstract
BACKGROUND AND AIMS People with substance use disorders (SUDs) frequently present to treatment with polysubstance use and mental health comorbidities. Different combinations of substance use and mental health problems require different treatment approaches. Our study aimed to: (i) identify the shared substance use classes among young people at treatment admission, (ii) determine which mental health symptoms, quality of life (QoL) and service types were associated with the identified substance use classes, and (iii) prospectively determine which substance use classes and service types were more likely to complete treatment. DESIGN Cross-sectional and prospective study using service and outcome data. SETTING Substance use treatment services in Queensland and New South Wales, Australia. PARTICIPANTS De-identified service and outcome measure data were extracted from the files of 744 clients aged 18-35 years (48% male) admitted into seven residential and four day-treatment programmes. MEASUREMENTS Substance use and severity among tobacco, alcohol, cannabis, cocaine, amphetamine-type stimulants, opioids, sedatives and inhalants. Other variables included: depression, anxiety, post-traumatic stress and psychotic symptoms, as well as QoL. FINDINGS Latent class analysis identified three polysubstance use classes: wide-ranging polysubstance users (WRPU; 22.45%), primary amphetamine users (56.45%) and alcohol and cannabis users (21.10%). The WRPU class had higher odds of psychotic symptoms than the alcohol and cannabis use class [odds ratio (OR) = 1.30; 95% confidence interval (CI) = 1.11-1.11]; and double the odds of residential programme enrolment than those in the amphetamine use class (OR = 2.35; 95% CI = 1.50-3.68). No other class differences on mental health or QoL variables were found. Clients enrolled in day-programmes had higher odds of completing treatment. CONCLUSIONS There appear to be high levels of polysubstance use among young people entering substance use treatment in Australia. Wide-ranging polysubstance users were more likely to report psychotic symptoms and be enrolled into a residential programme than primary amphetamine users and alcohol and cannabis users.

Abstract
BACKGROUND Treatment for opioid use disorder (OUD), particularly medication for OUD, is highly effective; however, retention in OUD treatment is a significant challenge. We aimed to identify key risk factors for premature exit from OUD treatment. METHODS We analyzed 2,381,902 cross-sectional treatment episodes for individuals in the U.S., discharged between Jan/1/2015 and Dec/31/2019. We developed classification models (Random Forest, Classification and Regression Trees (CART), Bagged CART, and Boosted CART), and analyzed 31 potential risk factors for premature treatment exit, including treatment characteristics, substance use history, socioeconomic status, and demographic characteristics. We stratified our analysis based on length of stay in treatment and service setting. Models were compared using cross-validation and the receiver operating characteristic area under the curve (ROC-AUC). RESULTS Random Forest outperformed other methods (ROC-AUC: 74%). The most influential risk factors included characteristics of service setting, geographic region, primary source of payment, and referral source. Race, ethnicity, and sex had far weaker predictive impacts. When stratified by treatment setting and length of stay, employment status and delay (days waited) to enter treatment were among the most influential factors. Their importance increased as treatment duration decreased. Notably, importance of referral source increased as the treatment duration increased. Finally, age and age of first use were important factors for lengths of stay of 2-7 days and in detox treatment settings. CONCLUSIONS The key factors of OUD treatment attrition identified in this analysis should be more closely explored (e.g., in causal studies) to inform targeted policies and interventions to improve models of care.

Abstract
BACKGROUND Literature on a longitudinal study of the determinants of treatment retention for patients with opioid dependence is limited. AIM To find out patient- and treatment-related (buprenorphine-naloxone-assisted treatment [BNX treatment] versus naltrexone treatment) predictors for retention in maintenance treatment. MATERIALS AND METHODS A total of 100 participants with opioid dependence were recruited by convenience sampling. The primary outcome was treatment retention - 3 months and 6 months postentry into maintenance treatment. Multiple assessments were done for the severity of opioid dependence and withdrawal, high-risk behavior, quality of life, and recovery capital - baseline and 3 and 6 months. The secondary outcome was to assess the change observed in the above-listed variables. RESULTS AND CONCLUSIONS Bivariate analysis across retained and the dropout groups brought out significant differences for some (type of opioids and route of administration) but not for other (age, employment, and education) patient-related factors. Multivariate analysis, adjusting for the type of maintenance treatment, rendered these associations statistically insignificant. BNX-based treatment (compared to naltrexone maintenance) was the most significant predictor of treatment retention both at the end of 3 months and 6 months. Even after controlling for the severity of opioid dependence and withdrawal, type and route of opioid use, and high-risk behavior, patients on BNX were eleven times (14 times at the end of 6 months) more likely to be retained in the treatment. BNX group had significant improvements in the domains of recovery capital, quality of life, addiction severity, and severity of opioid dependence. There is a need to scale up the BNX-assisted treatment program in India and elsewhere.
