Need to rethink tDCS protocols for the treatment of alcohol use disorder: Insights from a randomized sham-controlled clinical trial among detoxified inpatients.

OBJECTIVES: Alcohol use disorder (AUD) is a chronic disorder with various health problems. Reduced functioning of the Dorsolateral Prefrontal Cortex (DLPFC) is associated with impaired regulation of alcohol-seeking behaviors and increased cravings in individuals with AUD. This study aimed to investigate whether 10 add-on sessions of tDCS, over the left DLPFC in detoxified inpatients with AUD could reduce cravings and increase abstinence rates at three months. METHODS: Detoxified inpatients with AUD were randomly assigned to either treatment as usual (TAU) plus ten sessions of active tDCS over left DLPFC, or TAU plus ten sessions of sham tDCS treatment twice daily for five consecutive days. RESULTS: The results from the generalized linear mixed model (GLMM) revealed that time had a significant effect on OCDS scores, but neither treatment nor interaction between these two factors had a significant effect on OCDS scores The Chi-square test in the intention- to- treat analysis did not show a significant difference in complete abstinence rates between the active treatment group and the sham treatment group. CONCLUSIONS: we found that adding ten sessions of active tDCS over left DLPFC tDCS to the treatment as usual for AUD did not result in improved abstinence rates or reduced craving.

Effectiveness of smoking cessation intervention in opioid-dependent male subjects on buprenorphine maintenance treatment: An open-label trial.

Background: High prevalence (more than 80%) rates of tobacco smoking have been found both in, opioid-dependent subjects and among opioid-dependent subjects on opioid substitution treatment (OST) with buprenorphine or methadone. Aim: We aimed to explore the efficacy of combined nicotine replacement therapy (NRT) and individual counseling (IC) when compared to NRT alone in subjects on OST with buprenorphine. Methods: This study was carried out in a tertiary medical care center. It was an open-label randomized clinical trial. A total of 57 buprenorphine maintained smokers were recruited and randomized into two groups. They were assigned nicotine gum for 4 weeks plus either (1) a baseline IC session, and a second IC session after 1 week, or (2) simple advice to quit. In the first group, 31 subjects received NRT with IC and in the second group, 26 subjects received NRT plus simple advice to quit. The primary outcomes of this study were seven days point prevalence abstinence, biochemically confirmed by carbon monoxide (CO) breath analyzer, and reduction in smoking (mean no. of cigarettes or bidis/day). The smoking behavior during the 4 weeks follow-up period was assessed by the timeline follow-back (TLFB) method and confirmed by the CO breath analyzer. Results: The group of subjects who received NRT with IC showed higher rates of smoking cessation at the end of treatment (51%) as compared to the NRT and simple advice group where smoking cessation rates were around 8% (P < 0.001). Conclusion: A multi-component approach (pharmacotherapy and counseling) enhances treatment outcomes and enhances rates of abstinence from smoking.

Association Between Comorbid Psychiatric Disorders and Persistent Smoking After a Diagnosis of Chronic Obstructive Pulmonary Disease Among Patients Seeking Treatment at a Tertiary Care Hospital in India.

Introduction Smoking cessation is the most effective approach to slowing down the progression of chronic obstructive pulmonary disease (COPD). Despite this, almost half of COPD patients continue to smoke after diagnosis. COPD patients with current smoking status are more likely to have concurrent psychiatric comorbidities, for instance, depression and anxiety. These psychiatric disorders can contribute to the persistence of smoking in individuals with COPD. This study aimed to investigate predictors of smoking persistence in COPD patients. Materials and methods A cross-sectional study was conducted in the Outpatient Department (OPD) of the Department of Pulmonary Medicine in a tertiary care hospital from August 2018 to July 2019. Patients with COPD were screened for their smoking status. All subjects were then personally assessed for any psychiatric comorbidity using the Mini International Neuropsychiatric Interview (MINI), the Patient Health Questionnaire-9 (PHQ-9), and the Anxiety Inventory for Respiratory (AIR) Disease. Logistic regression was performed to compute the odds ratio (OR).  Results The study included a total of 87 COPD patients. Of the 87 COPD patients, 50 were current smokers, and 37 were past smokers. COPD patients with psychiatric disorders were four times more likely to continue smoking than those without psychiatric comorbidities (OR: 4.62, 95% CI: 1.46-14.54). The results showed that increasing PHQ-9 scores by one unit in COPD patients increased the likelihood of continuing to smoke by 27 percent. Conclusion In our multivariate analysis, current depression was found as a significant predictor of continued smoking in COPD patients. The present results are consistent with reports from previous research that depressive symptoms are associated with continued smoking in patients with COPD. COPD patients who are currently smoking should be examined for psychiatric disorders and treated concurrently to achieve effective smoking cessation.

Psychometric Validity of the Anxiety Inventory for Respiratory Disease (AIR) Scale in an Indian Sample of Chronic Obstructive Pulmonary Disease: A Cross-Sectional Study.

Introduction Researchers have found that chronic obstructive pulmonary disease (COPD) patients suffer from anxiety more than the general population. The Anxiety Inventory for Respiratory Disease (AIR) scale has been primarily used to assess non-somatic anxiety in COPD patients. The validity of AIR among COPD patients has not been evaluated in Indian settings. Therefore, this study was undertaken to determine the validity of AIR in these patients. The study aimed to evaluate concurrent criterion and discriminative validity of the AIR screening scale among patients with COPD using Mini International Neuropsychiatric Interview (MINI) 7.0.2 as the gold standard measure for diagnosing Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) anxiety disorders. Materials and methods A cross-sectional study was conducted in the Outpatients Department (OPD) of the Department of Pulmonary Medicine, All India Institute of Medical Sciences (AIIMS), New Delhi, from August 2018 to July 2019. A total of 100 patients diagnosed with COPD and aged 30 or above were recruited. All participants were further assessed in person by a psychiatry resident doctor using semi-structured proforma, MINI 7.0.2, and AIR Disease (Hindi). Mann-Whitney U and receiver operating characteristic (ROC) curves were conducted. The two-sided p-value of less than 0.05 was considered to be statistically significant. Results To assess the concurrent criterion validity of the AIR scale for screening clinical anxiety disorders, the ROC curve was constructed using MINI diagnoses of anxiety disorder as the gold standard measure. A cut-off score of 5.5 was found to maximize both the specificity and sensitivity of the AIR scale for screening anxiety disorders among COPD patients with COPD. The AIR scale showed a high sensitivity (95%) and specificity (89%) at this cut-point. Conclusion The findings of this study recommend a cut-off score of 5.5 on the AIR scale instead of 8 in previous studies, as maintaining the previously recommended cut-offs in Indian settings may lead to an increase in false negatives. This could have negative consequences for patients seeking treatment. Further studies may be planned to explore the psychometric properties of the current tool in a larger population.

Predictors of Inpatient Treatment Completion among Females with Opioid Use Disorder: Findings from a Tertiary Care Drug Dependence Treatment Centre of India.

INTRODUCTION: Studies have reported that females who drop out prematurely from inpatient treatment have poor treatment outcome. However, literature from India is limited in this regard. METHODS: We reviewed case records of female patients admitted with opioid use disorder at NDDTC, Ghaziabad between January 1, 2008 and December 31, 2012 to study the predictors of inpatient treatment completion among female patients with opioid use disorder in relation to their sociodemographic and clinical profile. RESULTS: Over the 5 years, 72 female patients were admitted with opioid dependence. During the study period, out of 72 patients, 44 (61.1%) were inpatient treatment completers and 28 (38.9%) were noncompleters. Mean length of ward stay was 5.1 ± 3.8 days and 16.2 ± 11.8 days for inpatient treatment noncompleters and completers, respectively, the difference being statistically significant (t = 4.845, P < 0.001). The multivariable analysis (adjusted for selected demographic characteristics as marital status, education, and employment) revealed that most women taking drug for relief from pain, having medical morbidity, and onset of opioids at age 25 years or more had a significantly greater likelihood for being treatment completers. CONCLUSION: Certain factors can help in identification of women opioid users who are at risk of leaving the treatment.

A naturalistic study of predictors of retention in treatment among emerging adults entering first buprenorphine maintenance treatment for opioid use disorders.

INTRODUCTION: Emerging adulthood (between the ages 18-25years) has been conceptualized as a specific developmental stage based on unique psychosocial characteristics. Opioids are commonly used drugs in this population. Few studies have reported predictors of retention in buprenorphine maintenance treatment among opioid-dependent emerging adults, particularly from India. Moreover, no study has examined outcomes with opioid maintenance treatment among emerging adults in non-clinical trial, naturalistic settings. The current study aimed to assess retention in buprenorphine maintenance treatment among emerging adults in a naturalistic setting. Also, it aimed to assess the factors associated with retention in treatment among these individuals. METHODS: The current study was a retrospective cohort study conducted at a substance use disorder treatment centre in northern part of India. The patients who received buprenorphine maintenance treatment between 1st January 2012 and 31st December 2014 were eligible for inclusion in the current study. The follow-up data of these subjects were assessed up to and including 31st March 2015. Information was retrieved on socio-demographic variables. The information related to substance use included type of substance, duration of use, age of onset, motive of use, route of administration and source of procurement. Additionally, details of buprenorphine dose, dispensing pattern, induction settings were recorded. Cox regression analysis was carried out to assess the predictors of retention in buprenorphine maintenance treatment. RESULTS: Of 68 emerging adults, 33.8% were retained in treatment at 90days, 19.1% at 6months and 11.7% at one year. After controlling for various covariates in adjusted Cox regression analysis, substance use in first degree relatives (AHR: 2.40, 95% CI 1.33-4.31), lower daily buprenorphine dose (AHR: 0.86, 95% CI 0.78-0.94) and past month injection drug use (AHR: 0.30, 95% CI 0.14-0.66) were found to be the significant predictors of treatment dropout. CONCLUSIONS: The findings of the current study help understand the predictors of retention in buprenorphine maintenance treatment among emerging adults in a real-world situation. These findings will help guide formulation of responsive and relevant buprenorphine maintenance treatment program for the emerging adults.

Alcohol-Related Dementia and Neurocognitive Impairment: A Review Study.

CONTEXT: Alcohol consumption has escalated rapidly in many countries over the past decade. Evidence suggests a correlation between alcohol use and cognitive decline. We have systematically reviewed the concept and controversies, epidemiology, nosology, neuropathology and neurobiology, neuropsychology and management updates of alcohol-related dementia (ARD) in this paper. EVIDENCE ACQUISITION: We retrieved papers for this review by searching the PubMed database for terms "alcohol and dementia", "alcohol and cognitive impairment", and "alcohol and wernicke-korsakoff" mentioned in the title of the published papers. A total of 131 studies showed up. Appropriate studies were shortlisted and included (n = 72). Cross-references if relevant were considered from the selected studies. Eligible articles were fully read by the authors and the results were compiled. RESULTS: The prolonged and excessive use of alcohol may lead to structural and functional brain damage, leading to ARD. The cognitive deficits are most frequently observed in domains of visuospatial functions, memory and executive tasks, with a potential of partial recovery if abstinence is maintained. However, there are doubts regarding the etiopathogenesis, nosological status, prevalence and diagnostic criteria for ARD, due to difficulty in assessment and various confounding factors. CONCLUSIONS: With growing cohort of young and middle-aged people, there is a probable risk of upsurge of ARD. Presently, there are dilemmas over the diagnosis of independent ARD. Thus, there is a need to develop evidence-based guidelines for diagnosis and management of ARD through further systematic studies.

Profile of female patients seeking in-patient treatment for prescription opioid abuse from a tertiary care drug dependence treatment centre from India.

BACKGROUND & OBJECTIVES: There has been a limited focus on prescription drug abuse among women in the country. Choice of psychoactive substance, reasons for initiation and co-occurring disorders have been found to be different among men and women. The current study was aimed at studying the profile of female patients seeking in-patient treatment for prescription drug use over a period of five years at a tertiary care drug dependence treatment centre in India. METHODS: Case records of all female patients admitted with substance use disorder at a national level drug dependence treatment centre in north India across five years (between January 2008 and December 2012) were reviewed retrospectively to study their socio-demographic and clinical profile. The information was gathered using a semi-structured proforma and detailed case records. Abstinence, relapse and retention rates were calculated. RESULTS: Over the five years, 31 female patients were admitted with prescription drug abuse. Of them, 12 (39%) used prescription opioids and 11 (36%) used prescription opioid along with benzodiazepines. Commonest prescription opioid was pentazocine used by 87 per cent of the women. Twenty two (71%) women were introduced to opioid by medical practitioners and commonest reason for introduction was pain (among 48%). Common co-occurring psychiatric diagnoses were depressive disorder (26%), cluster B traits/disorder (19%) and somatoform disorder (13%). Eight women did not complete treatment and left against medical advice. Thirteen women were advised maintenance treatment, and 70 per cent of them were retained for at least six months. INTERPRETATION & CONCLUSIONS: Our findings revealed a link between mental illness, pain and non-medical use of prescription opioids among women. Majority of these women received opioids as a legitimate prescription form physician. Therefore, these legitimate prescribers should be trained for pain management to facilitate proper treatment of pain and to prevent the subsequent misuse of these medicines. Female patients with frequent pain complaints should be assessed for psychopathology while prescribing opioids.

Catatonia as presenting clinical feature of subacute sclerosing panencephalitis.

Catatonia is not a usual clinical presentation of subacute sclerosing panencephalitis (SSPE), especially in the initial stages of illness. However, there is only one reported case of SSPE presenting as catatonia among children. In this report, however, there were SSPE-specific changes on EEG and the catatonia failed to respond to lorazepam. We describe a case of SSPE in a child presenting as catatonia that presented with clinical features of catatonia and did not have typical EEG findings when assessed at first contact. He responded to lorazepam and EEG changes emerged during the course of follow-up.
