The MAIT TCRß chain contributes to discrimination of microbial ligand.

Mucosal-associated invariant T (MAIT) cells are key players in the immune response against microbial infection. The MAIT T-cell receptor (TCR) recognizes a diverse array of microbial ligands, and recent reports have highlighted the variability in the MAIT TCR that could further contribute to discrimination of ligand. The MAIT TCR complementarity determining region (CDR)3ß sequence displays a high level of diversity across individuals, and clonotype usage appears to be dependent on antigenic exposure. To address the relationship between the MAIT TCR and microbial ligand, we utilized a previously defined panel of MAIT cell clones that demonstrated variability in responses against different microbial infections. Sequencing of these clones revealed four pairs, each with shared (identical) CDR3α and different CDR3ß sequences. These pairs demonstrated varied responses against microbially infected dendritic cells as well as against 5-(2-oxopropylideneamino)-6-d-ribitylaminouracil, a ligand abundant in Salmonella enterica serovar Typhimurium, suggesting that the CDR3ß contributes to differences in ligand discrimination. Taken together, these results highlight a key role for the MAIT CDR3ß region in distinguishing between MR1-bound antigens and ligands.

Relation between age at first alcohol drink & adult life drinking patterns in alcohol-dependent patients.

Background & objectives: Age at first drink has its influence on later life drinking patterns. The association between age at first drink and adult alcohol consumption has not been studied in clinical population. This study was aimed to determine the age at first drink and its correlation with adult life drinking patterns in alcohol-dependent patients. Methods: Adult participants with alcohol dependence were included from the inpatient and outpatient wards of a tertiary care de-addiction facility in India. Questionnaires administered were National Institute on Alcohol Abuse and Alcoholism-Quantity Frequency for alcohol and the Fagerstrom Test for Nicotine Dependence for tobacco. Results: Of the 99 participants (92% males) with mean age 37±8.36 yr, mean age at first drink was 21.14±5.33 yr. After controlling for age, satisfaction with life scores and smoking, age at first drink showed a significant negative correlation with drinking days per week (r=-0.259, P=0.012), typical drink per day (r=-0.218, P=0.035) and maximum drinks in the previous month/year (r=-0.233, -0.223 and P=0.024, 0.031, respectively). Interpretation & conclusions: Our study suggested that earlier age of first drink correlated with chronic heavy drinking patterns in later adult life in alcohol-dependent patients. This may have implications for alcohol control policies determining the age for legal consumption.

Task shifting of frontline community health workers for cardiovascular risk reduction: design and rationale of a cluster randomised controlled trial (DISHA study) in India.

BACKGROUND: Effective task-shifting interventions targeted at reducing the global cardiovascular disease (CVD) epidemic in low and middle-income countries (LMICs) are urgently needed. METHODS: DISHA is a cluster randomised controlled trial conducted across 10 sites (5 in phase 1 and 5 in phase 2) in India in 120 clusters. At each site, 12 clusters were randomly selected from a district. A cluster is defined as a small village with 250-300 households and well defined geographical boundaries. They were then randomly allocated to intervention and control clusters in a 1:1 allocation sequence. If any of the intervention and control clusters were <10 km apart, one was dropped and replaced with another randomly selected cluster from the same district. The study included a representative baseline cross-sectional survey, development of a structured intervention model, delivery of intervention for a minimum period of 18 months by trained frontline health workers (mainly Anganwadi workers and ASHA workers) and a post intervention survey in a representative sample. The study staff had no information on intervention allocation until the completion of the baseline survey. In order to ensure comparability of data across sites, the DISHA study follows a common protocol and manual of operation with standardized measurement techniques. DISCUSSION: Our study is the largest community based cluster randomised trial in low and middle-income country settings designed to test the effectiveness of 'task shifting' interventions involving frontline health workers for cardiovascular risk reduction.

Adverse Childhood Experiences, Coping and Resilience in Persons with Alcohol Use Disorder and Their Non-drinking Siblings in High-density Families: A Case-control Study.

Background: Adverse childhood experiences (ACEs) increase the odds of alcohol use disorder (AUD). Aim: To study the ACEs, coping, and resilience in persons with AUD and their non-drinking siblings from high-density families. Methods: The study used a case-control study design. Using purposive sampling, 135 participants were selected; the sample consists of persons with AUD (n = 45), non-drinking siblings (n = 45), and healthy controls (n = 45), selected from out-patient and in-patient services from a government-run de-addiction centre in Bengaluru. Individuals were administered an ACEs questionnaire, Brief-COPE, and Connor-Davison Resilience scale. Descriptive statistics, Friedman's test, and Bonferroni's post-hoc test, Binary Logistic Regression were used for analysis. Results: ACEs, coping, and resilience significantly differ across the three groups. Persons with AUD and their non-drinking siblings are comparable in terms of ACEs and having dysfunctional family members. Non-drinking siblings and healthy controls have similar coping and resilience. None of the healthy controls had dysfunctional family members. Conclusion: ACEs are more prevalent and more frequent in persons with AUD. Individuals with AUD showed higher avoidant coping and lower resilience than their non-drinking siblings and healthy controls. Early identification of ACEs and interventions to build resilience and coping strategies could prevent individuals from developing AUD in high-density families.

Online gaming motives, family relationships, and personality among Indian youth.

Background: Youth involvement in gaming has become an important concern for mental health professionals due to its significant impact on functionality and relationships. However, the gaming motives and associated family relationships and personality traits in the Indian context are poorly understood. Aim: The study examined problematic online gaming, including Internet gaming disorder in connection to gaming motives and personality, especially as they impact family relationships among Indian youth. Materials and Methods: The study consisted of 179 participants (86 males; 93 females) with the age range of 18-25 years who were involved in Internet gaming in the last 1 year. The subjects were recruited using an online survey. Tools used were brief and included the Gaming Usage Questionnaire, Internet Gaming Disorder Scale-Short-Form, Motivation for Online Gaming Questionnaire UCLA Loneliness Scale, Sheehan Disability Scale, Brief Family Relationships Questionnaire, and MINI International Personality Item Pool. Results: The mean age of the participants was 21.99 ± 2.202 years. A stepwise multivariate regression analysis indicated that escape and competition motives, low cohesion in family relationships, low level of conscientiousness, and low level of intellect/imagination contributed to problematic gaming behaviors. Conclusions: The study established a relationship between gaming motives and both internal and external factors associated with problematic online gaming. Generalizing the findings across a larger youth population would help in developing informed preventive measures to reduce the risk of developing a gaming disorder.

Lived Experiences of Intimate Partner Violence and Help-seeking among Wives of Persons with Alcohol Dependence: A Thematic Analysis.

Background: Worldwide, intimate partner violence (IPV) is a significant public health problem. Most of the wives of persons with alcohol dependence (PwAD) experience IPV in their lifetime. The study examined lived experiences of IPV among wives of PwAD. Methods: Qualitative research study design was used. Twenty participants were recruited using the consecutive sampling method. The researcher used an in-depth interview guide to collect the data. ATLAS.ti.9 software was used to analyse the qualitative data. Thematic analysis was used for coding and emerging themes. The thematic analysis yielded four themes generated from the in-depth interview: (1) reasons for the IPV, (2) help-seeking, (3) barriers in help-seeking and (4) coping with IPV. Conclusion: Survivors of IPV do not seek help due to self-stigma, unavailable resources, and lack of awareness about treatment for alcohol dependence. Clinicians should routinely screen for IPV among female spouses of persons with alcohol-dependent syndrome and provide psychosocial interventions for the survivors of IPV.

Ethics of qualitative research in substance use disorders.

Ethics in substance use disorder research has evolved through the years into two distinct school of thoughts, including neuro-ethics and social ethics. Qualitative methods of conducting studies provide rich descriptive knowledge of underlying processes in use of substances, although their governing ethical principles and decision-making are fairly blurred. By incorporating case studies, in-depth interviews, focus groups or visual methods, substance use disorder research can be considerably enhanced. The present paper examines features of conducting qualitative research among substance users and the ethical frameworks that one needs to be mindful of. Understanding potential dilemmas, pitfalls, and challenges in conducting qualitative research among individuals with substance use disorders would be a useful way to build on the body of qualitative research.

Rare case of chronic naphthalene ball ingestion in a young Indian woman.

Chronic oral abuse of naphthalene balls is extremely rare. It is associated with different types of metabolic toxicity, neurological deficits and multiple organ failure. However, the psychological implication of naphthalene abuse is poorly understood. This is a unique case report of a 29-year-old lady who presented with a 17 year history of naphthalene ball consumption. Historically, there have been self-harm behaviors, fire setting, cleaning compulsions, and involuntary motor movements associated with naphthalene. A series of assessments were conducted to assess her personality, psychiatric symptoms and cognitive functions. Additionally, blood tests, CT scan and MRI were done. The patient's profile indicated no apparent medical, neurological or cognitive impairments. Her psychological profile revealed significant co-morbidities and marked personality pathology. The case study provides useful insights into the presentation of chronic naphthalene ball ingestion in an Indian woman, thereby indicating the need to identify psychosocial and biological markers longitudinally. It also highlights recognition of common household items that can be abused, suggesting better understanding of protecting vulnerable individuals from the same.

Early maladaptive schemas in substance use disorders in the Indian context: Theoretical and therapeutic implications.

Schema theory seems to be a relevant perspective in the overall understanding of substance use disorders (SUDs). Early maladaptive schemas (EMSs) are defined as self-defeating emotional and cognitive patterns that begin early in our development, repeat throughout life, and act as risk factors for mental health problems and substance use (SU). SU behavior acts as a means by which users attempt to avoid triggering the unpleasant and negative emotions inherent in their elevated schema. Thus, SU is often seen as a coping mechanism in schema theory. This has important implications in terms of assessment, treatment, and planning of interventions. Schema therapy would be a valuable addition to the current therapy practice, which emphasizes a dual focus on both SU and EMSs and uses an integrated framework of cognitive, behavioral, and experiential techniques to target and modify EMSs.

SARS-CoV-2 infection alters mitochondrial and cytoskeletal function in human respiratory epithelial cells mediated by expression of spike protein.

Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, SCV2), which has resulted in higher morbidity and mortality rate than other respiratory viral infections, such as Influenza A virus (IAV) infection. Investigating the molecular mechanisms of SCV2-host infection vs IAV is vital in exploring antiviral drug targets against SCV2. We assessed differential gene expression in human nasal cells upon SCV2 or IAV infection using RNA sequencing. Compared to IAV, we observed alterations in both metabolic and cytoskeletal pathways suggestive of epithelial remodeling in the SCV2-infected cells, reminiscent of pathways activated as a response to chronic injury. We found that spike protein interaction with the epithelium was sufficient to instigate these epithelial responses using a SCV2 spike pseudovirus. Specifically, we found downregulation of the mitochondrial markers SIRT3 and TOMM22. Moreover, SCV2 spike infection increased extracellular acidification and decreased oxygen consumption rate in the epithelium. In addition, we observed cytoskeletal rearrangements with a reduction in the actin-severing protein cofilin-1 and an increase in polymerized actin, indicating epithelial cytoskeletal rearrangements. This study revealed distinct epithelial responses to SCV2 infection, with early mitochondrial dysfunction in the host cells and evidence of cytoskeletal remodeling that could contribute to the worsened outcome in COVID-19 patients compared to IAV patients. These changes in cell structure and energetics could contribute to cellular resilience early during infection, allowing for prolonged cell survival and potentially paving the way for more chronic symptoms. IMPORTANCE COVID-19 has caused a global pandemic affecting millions of people worldwide, resulting in a higher mortality rate and concerns of more persistent symptoms compared to influenza A. To study this, we compare lung epithelial responses to both viruses. Interestingly, we found that in response to SARS-CoV-2 infection, the cellular energetics changed and there were cell structural rearrangements. These changes in cell structure could lead to prolonged epithelial cell survival, even in the face of not working well, potentially contributing to the development of chronic symptoms. In summary, these findings represent strategies utilized by the cell to survive the infection but result in a fundamental shift in the epithelial phenotype, with potential long-term consequences, which could set the stage for the development of chronic lung disease or long COVID-19.

Behavioral Activation for Comorbid Depression in People With Noncommunicable Disease in India: Protocol for a Randomized Controlled Feasibility Trial.

BACKGROUND: The increasing burden of depression and noncommunicable disease (NCD) is a global challenge, especially in low- and middle-income countries, considering the resource constraints and lack of trained human resources in these settings. Effective treatment of depression in people with NCDs has the potential to enhance both the mental and physical well-being of this population. It will also result in the effective use of the available health care resources. Brief psychological therapies, such as behavioral activation (BA), are effective for the treatment of depression. BA has not been adapted in the community health care services of India, and the feasibility of using BA as an intervention for depression in NCD and its effectiveness in these settings have not been systematically evaluated. OBJECTIVE: Our objective is to adapt BA for the Indian NCD context and test the acceptability, feasibility, and implementation of the adapted BA intervention (BEACON intervention package [BIP]). Additionally, we aim to test the feasibility of a randomized controlled trial evaluation of BIP for the treatment of depression compared with enhanced usual care. METHODS: Following well-established frameworks for intervention adaptation, we first adapted BA (to fit the linguistic, cultural, and resource context) for delivery in India. The intervention was also adapted for potential remote delivery by telephone. In a randomized controlled trial, we will be testing the acceptability, feasibility, and implementation of the adapted BA intervention (BIP). We shall also test if a randomized controlled feasibility trial can be delivered effectively and estimate important parameters (eg, recruitment and retention rates and completeness of follow-up) needed to design a future definitive trial. RESULTS: Following the receipt of approval from all the relevant agencies, the development of the BIP was started on November 28, 2020, and completed on August 18, 2021, and the quantitative data collection was started on August 23, 2021, and completed on December 10, 2021. Process evaluation (qualitative data) collection is ongoing. Both the qualitative and quantitative data analyses are ongoing. CONCLUSIONS: This study may offer insights that could help in closing the gap in the treatment of common mental illness, particularly in nations with limited resources, infrastructure, and systems such as India. To close this gap, BEACON tries to provide BA for depression in NCDs through qualified NCD (BA) counselors integrated within the state-run NCD clinics. The results of this study may aid in understanding whether BA as an intervention is acceptable for the population and how feasible it will be to deliver such interventions for depression in NCD in South Asian countries such as India. The BIP may also be used in the future by Indian community clinics as a brief intervention program.

Selective aryl hydrocarbon receptor modulator-mediated repression of CD55 expression induced by cytokine exposure.

Modulation of aryl hydrocarbon receptor (AHR) activity by a class of ligands termed selective AHR modulators (SAhRMs) has been demonstrated to attenuate proinflammatory gene expression and signaling, including repression of cytokine-mediated induction of acute-phase genes (e.g., Saa1). These effects are observed to occur through an AHR-dependent mechanism that does not require canonical signaling through dioxin response elements. Previously, we have demonstrated that the SAhRM 3',4'-dimethoxy-α-naphthoflavone (DiMNF) can repress the cytokine-mediated induction of complement factor genes. Here, we report that the activation of the AHR with DiMNF can suppress cytokine-mediated induction of the membrane complement regulatory protein CD55. When CD55 is expressed on host cells, it facilitates the decay of the complement component 3 (C3) convertase, thereby protecting the cell from complement-mediated lysis. Tumor cells often exhibit elevated CD55 expression on the cell surface in the inflammatory microenvironment of the tumor, and such enhanced expression could represent a means of escaping immune surveillance. DiMNF can repress the cytokine-mediated induction of CD55 mRNA and protein. Luciferase reporter analysis has identified possible response elements on the CD55 promoter, which may be targets for this repression. A C3 deposition assay with [(125)I]C3 revealed that repression of cytokine-mediated CD55 expression by DiMNF led to an increase of C3 deposition on the surface of Huh7 cells, which would likely stimulate the formation of the membrane attack complex. These results suggest that SAhRMs such as DiMNF have therapeutic potential in regulating the immune response to tumor formation.

Integrating mental health into cardiovascular disease research in India.

Mental health refers to a diverse field where individuals can cope with daily stress, realize their potential and maintain a state of well-being. In recent years, there has been increasing recognition of the influence of mental health on general health, and in particular on cardiovascular diseases and their risk factors. Epidemiological research has focused on several psychosocial components including social determinants, comorbid psychiatric disorders, psychological stress, coping styles, social support, burden on the family, well-being, life satisfaction, personality and cognitive factors in connection with cardiovascular diseases. There is epidemiological research in India that integrates mental health with common cardiovascular diseases such as coronary health disease and stroke. Data from mental health research is sufficiently compelling to highlight the role of chronic stress, socioeconomic status and psychiatric disorders such as depression, substance use, social networks and support in relation to vulnerability to cardiovascular diseases. There are psychosocial consequences of cardiovascular diseases including deficits in the domains of life skills, coping skills and neurocognition, in addition to caregiver burden. The implications of bio-psychosocial models of assessments and interventions that target complex individual and contextual variables simultaneously on cardiovascular treatment outcomes have highlighted the importance of studying mental health in Indian settings. Integration of mental health into mainstream research is the need of the hour. A multidimensional approach to accomplish this is required including at the level of research conceptualization, discussions with key stakeholders, at the policy level, at the institutional level, and at the clinical and community level.

Effectiveness of multimodal psychotherapeutic intervention for internet gaming disorder.

BACKGROUND: Large number of studies on Internet gaming disorder (IGD) have primarily focused on ascertaining its psychological correlates. Few studies have focused on developing and assessing effectiveness of multimodal psychotherapeutic intervention programs. This intervention focused on minimizing salience, pre-occupation, conflict related to gaming and enhancing the overall quality of life, inclusive of psychological health, physical health, and environmental problems in individuals with IGD. At present, there appear to be no such studies in the Indian context. METHODS: In this study, we developed and assessed the effectiveness of an intervention manual for IGD. The intervention program consisted of ten 60-minutes sessions with one therapist administering sessions once in each week. The interventions included motivational enhancement strategies, cognitive restructuring, behavioral strategies and relapse prevention. The outcomes from intervention were measured in terms of improvement in IGD, IAT, and overall quality of life. Our assessments, both at baseline and post-intervention consisted of Internet Addiction Test (IAT), Internet Gaming Disorder Test (IGD-20) and the Whoqol-Bref. A total sample of 40 was selected out of which 33 individuals completed the 10 sessions of multimodal psychotherapy program and post assessments. RESULTS: A total of 40 participants (age: M = 20.25, SD = 5.39) enrolled, out of which 33 completed the entire intervention program of 10 sessions and showed significant improvements. The IAT and IGD-20 showed significant difference in the scores for before treatment (M = 52.88, SD = 16.25) and after treatment (M = 42.87, SD = 11.31; t (32) = 5.10, p = 0.000) conditions; and right before treatment (M = 56.88, SD = 19.25) and after treatment (M = 47.87, SD = 15.31; t (32) = 6.94, p = 0.000) conditions respectively. The internet addiction and internet gaming disorder scores showed a similar degree of severity reductions on the IAT and IGD-20 respectively at the end of week 8. In addition, the participants showed significant improvements in the quality of life inclusive of physical and psychological health post the completion of intervention program. LIMITATIONS: The sample size of the study was small and assessments for evaluation of other psychological symptoms like depression, anxiety could have been conducted. CONCLUSION: The intervention program indicated a substantial change in the IGD scores at post- assessment. A study on a larger sample to assess the validity of the manualized multimodal psychotherapy program for IGD needs to be conducted. In addition, this manualized intervention program can be useful for administering structured intervention for IGD by mental health professionals working in the area of internet gaming disorder.

Structured Lifestyle Modification Interventions Involving Frontline Health Workers for Population-Level Blood Pressure Reduction: Results of a Cluster Randomized Controlled Trial in India (DISHA Study).

Background Population-wide reduction in mean blood pressure is proposed as a key strategy for primary prevention of cardiovascular disease. We evaluated the effectiveness of a task-sharing strategy involving frontline health workers in the primary prevention of elevated blood pressure. Methods and Results We conducted DISHA (Diet and lifestyle Interventions for Hypertension Risk reduction through Anganwadi Workers and Accredited Social Health Activists) study, a cluster randomized controlled trial involving 12 villages each from 4 states in India. Frontline health workers delivered a custom-made and structured lifestyle modification intervention in the selected villages. A baseline survey was conducted in 23 and 24 clusters in the control (n=6663) and intervention (n=7150) groups, respectively. The baseline characteristics were similar between control and intervention clusters. In total 5616 participants from 23 clusters in the control area and 5699 participants from 24 clusters in the intervention area participated in a repeat cross-sectional survey conducted immediately after the intervention phase of 18-months. The mean (SD) systolic blood pressure increased from 125.7 (18.1) mm Hg to 126.1 (16.8) mm Hg in the control clusters, and it increased from 124.4 (17.8) mm Hg to 126.7 (17.5) mm Hg in the intervention clusters. The population average adjusted mean difference in difference in systolic blood pressure was 1.75 mm Hg (95% CI, -0.21 to 3.70). Conclusions Task-sharing interventions involving minimally trained nonphysician health workers are not effective in reducing population average blood pressure in India. Expanding the scope of task sharing and intensive training of health workers such as nurses, nutritionists, or health counselors in management of cardiovascular risk at the population level may be more effective in primary prevention of cardiovascular disease.

Influence of Shared Environments in Development of Alcohol Use Disorder: A Scoping Review.

Background: The influence of shared genetic vulnerability is well-known in the development of alcohol use disorder. However, there is a dearth of studies on shared environments. Hence, the present study aimed to ascertain the influence of shared environments in the development of alcohol use disorder. Aim: To examine the influence of adverse childhood experiences, parental bonding, and temperament in the development of alcohol use disorder. Methods: Preferred Reporting Items for Systematic reviews and Meta-Analysis extension for Scoping Reviews (PRISMA-ScR) guidelines were followed. Studies were identified through search engines such as PubMed, Embase, and PsychInfo, CINAHL databases. Peer-reviewed articles in English published during 2000 - 2021 were included for the review. Results: About 47 articles were considered for the scoping review. Shared environmental factors such as adverse childhood experiences or childhood trauma within 18 years of life, novelty, adventure-seeking, cyclothymia, and immediate need for gratification contribute to alcohol use disorder development. Positive parenting is associated with a lower incidence of AUD. Conclusion: Understanding the influence of shared environments and providing tailor-made psycho-social interventions would reduce the risk and prevent alcohol use disorder development..

Alternative splicing of MR1 regulates antigen presentation to MAIT cells.

Mucosal Associated Invariant T (MAIT) cells can sense intracellular infection by a broad array of pathogens. These cells are activated upon encountering microbial antigen(s) displayed by MR1 on the surface of an infected cell. Human MR1 undergoes alternative splicing. The full-length isoform, MR1A, can activate MAIT cells, while the function of the isoforms, MR1B and MR1C, are incompletely understood. In this report, we sought to characterize the expression and function of these splice variants. Using a transcriptomic analysis in conjunction with qPCR, we find that that MR1A and MR1B transcripts are widely expressed. However only MR1A can present mycobacterial antigen to MAIT cells. Coexpression of MR1B with MR1A decreases MAIT cell activation following bacterial infection. Additionally, expression of MR1B prior to MR1A lowers total MR1A abundance, suggesting competition between MR1A and MR1B for either ligands or chaperones required for folding and/or trafficking. Finally, we evaluated CD4/CD8 double positive thymocytes expressing surface MR1. Here, we find that relative expression of MR1A/MR1B transcript is associated with the prevalence of MR1 + CD4/CD8 cells in the thymus. Our results suggest alternative splicing of MR1 represents a means of regulating MAIT activation in response to microbial ligand(s).

MR1 recycling and blockade of endosomal trafficking reveal distinguishable antigen presentation pathways between Mycobacterium tuberculosis infection and exogenously delivered antigens.

The MHC-Ib molecule MR1 presents microbial metabolites to MR1-restricted T cells (MR1Ts). Given the ubiquitous expression of MR1 and the high prevalence of human MR1Ts, it is important to understand the mechanisms of MR1-dependent antigen presentation. Here, we show that MR1-dependent antigen presentation can be distinguished between intracellular Mycobacterium tuberculosis (Mtb) infection and exogenously added antigens. Although both Mtb infection and exogenously added antigens are presented by preformed MR1, only exogenously added antigens are capable of reusing MR1 that had been bound to the folic acid metabolite 6-formylpterin (6-FP). In addition, we identify an endosomal trafficking protein, Syntaxin 4, which is specifically involved in the presentation of exogenously delivered antigens but not Mtb-dependent antigen presentation. These data reveal there are multiple ways that MR1 can sample antigens and that MR1-mediated sampling of intracellular Mtb infection is distinguishable from the sampling of exogenously added antigens.

A Transdiagnostic Approach to Interventions in Addictive Disorders- Third wave therapies and other current interventions.

Recent research points to a shift from categorical diagnoses to a dimensional understanding of psychopathology and mental health disorders. In parallel, there has been a rise in newer psychosocial treatment modalities, which are inherently transdiagnostic. Transdiagnostic approaches are those that identify core vulnerabilities and apply universal principles to therapeutic treatment. As treatment of substance use disorders (SUD) must invariably accommodate such vulnerabilities, clinicians are finding such interventions useful. Therapies like Acceptance and Commitment Therapy (ACT), Dialectical Behavioural Therapy (DBT), Metacognitive Therapy, Mindfulness-Based Relapse Prevention (MBRP) use a transdiagnostic framework and are backed by evidence in the last 3-5 years. In this paper we first highlight the conceptual understanding of SUD through these frameworks and then discuss their clinical applications along with specific techniques that have been particularly useful with this population.

Personality Profile and Short-term Treatment Outcome in Patients with Alcohol Dependence: A Study from South India.

BACKGROUND: Studying personality profiles allows researchers to generate important hypotheses in risk factors and correlates of alcohol use/misuse. Studies examining the association between personality traits and treatment outcome are limited in India. We studied the correlation between personality and treatment outcome in patients with alcohol dependence. METHODS: Adult participants with alcohol dependence were recruited from the inpatient and outpatient wards of de-addiction unit of a tertiary care facility in India using a prospective design and followed up after 3 months. Questionnaires administered were revised NEO personality inventory (NEO-PI-R), alcohol use disorders identification test, and advanced warning of alcohol relapse (AWARE). RESULTS: Out of 99 recruited participants (92% males) with mean age of 37 (±8.36) years, 82 (82.8%) patients were followed up to 3 months. E4 (activity) facet of the extraversion domain in the NEO-PI-R significantly correlated with the baseline drinking scores (r = 0.204, P = 0.042, n = 99) and AWARE scores (r = 0.276, P = 0.043, n = 54). There was a significant negative correlation between the E2 (gregariousness) facet and satisfaction with life scores (r = -0.211, P = 0.036, n = 99). Age at first drink was significantly lower among relapsers (P = 0.021). CONCLUSION: Our study suggests that factors related to extraversion, specifically, high activity might be associated with higher drinking as well as higher risk of alcohol relapse. Predicting alcohol relapse by studying the personality traits would help clinicians in improving treatment outcomes.
