RESUMO
OBJECTIVE: Buprenorphine (BUP) effectively suppresses non-prescription opioid use and increases treatment retention in opioid use disorder (OUD). However, short prescription length may interfere with treatment retention and recovery. We wanted to examine whether the outcomes of BUP treatment differ in high (HPL up to 4 wk) and low-prescription (LPL 1-2 wk) length groups. METHODS: We compared time to treatment discontinuation (TD), non-prescription opioid-positive urine screen, buprenorphine-negative urine screen, and self-reported non-prescription opioid use between two different cohorts of LPL (case record: June 2018 to August 2019; n = 105; observation endpoint: 31 October 2019) and HPL groups (case record: June 2020 to Aug 2021; n = 133; observation endpoint: 31 October 2021). We used Kaplan-Meier survival analysis and log-rank tests for between-group comparisons. We used Cox regression analysis to adjust for age, opioid potency, comorbidities, family income, and marital status. RESULTS: Subjects' age and buprenorphine dose were significantly lower, and the percentage of high-potency opioid users was significantly higher in the LPL group. In the unadjusted survival analysis, the median time to BUP discontinuation in the HPL was longer than that of the LPL [LPL= 22.4 ± 4.3 wk; HPL = 33.1 ± 8.5 wk; χ2(1)= 5.7; p=.02]. The survival distributions of other outcomes did not differ between groups. When adjusted for covariates, neither the prescription length nor other covariates independently predicted any treatment outcome. CONCLUSION: Higher prescription length might be associated with longer treatment retention. We provide preliminary evidence to support greater flexibility in BUP treatment, enhancing its scalability and attractiveness.

BACKGROUND: Alcohol use disorder (AUD) is a relapsing-remitting disease that accounted for a sizable proportion of all-cause adult inpatient stays. OBJECTIVES: To determine the predictors of any and multiple readmissions to inpatient care for AUD within 5 years of the index admission. METHODS: This retrospective, register-based cohort study assessed consecutive patients with AUD admitted to a publicly-funded inpatient service between January 2007 and December 2014. Binary logistic regression was used to determine independent predictors for readmissions based on relevant demographic, clinical, and treatment variables that showed significant differences (p < 0.05) on univariate analysis. RESULTS: Among 938 patients (age 35.9 ± 10.3 years; duration of alcohol use 159.6 ± 104.5 months; dual diagnosis 19%; comorbidity of substance use disorder 49.3%; medical disorder 34.8%, 299 (31.9%) and 115 (12.3%) had any and multiple readmissions, respectively. Comorbid "severe mental illness" (Odds ratio [OR] 1.99, 95% confidence interval [CI] 1.11-3.57) and urban residence (OR 1.58, 95% CI 1.13-2.18) increased the odds of any readmission; "Improved" status at discharge (OR 0.51, 95% CI 0.35-0.72) during index hospitalization reduced odds of readmission. Additionally, any medical or psychiatric comorbidities increased (OR 2.23, 95% CI 1.26-3.97), and comorbid substance use disorder decreased (OR 0.41, 95% CI 0.19-0.89) risk of multiple readmissions. CONCLUSIONS: Clinicians could identify patients at-risk for any and multiple readmissions during the index hospitalization. A policy aimed at reducing the risk of rehospitalization, healthcare cost, and stigma should pay attention to the predictors of readmission. Such policy should further benefit resource-limited settings.

AIMS: We conducted a cross-sectional survey to estimate the prevalence and clinical manifestation of disulfiram ethanol reaction (DER) and isopropanol toxicity (IT) in patients with alcohol use disorders, on disulfiram. Alcohol-based hand rub contains either ethanol or isopropanol or both. COVID-19 pandemic has led to wide scale usage of sanitizers. Patients with alcohol use disorders, on disulfiram, might experience disulfiram ethanol like reactions with alcohol-based sanitizers. METHODS: We telephonically contacted 339 patients, prescribed disulfiram between January 2014 and March 2020. The assessment pertained to the last 3 months (i.e. third week of March to third week of June 2020). RESULT: The sample consisted of middle-aged men with a mean 16 years of alcohol dependence. Among the 82 (24%) patients adherent to disulfiram, 42 (12.3%) were using alcohol-based hand rubs. Out of these, a total of eight patients (19%; 95% CI 9-33) had features suggestive of DER; four of whom also had features indicative of IT. Five patients (62.5%) had mild and self-limiting symptoms. Severe systemic reactions were experienced by three (37.5%). Severe reactions were observed with exposure to sanitizers in greater amounts, on moist skin or through inhalation. CONCLUSION: Patients on disulfiram should be advised to use alternate methods of hand hygiene.

BACKGROUND AND OBJECTIVES: Chronic opioid exposure has been linked with neurocognitive impairments. Evidence of residual impairment with cannabis use is less consistent. We investigated whether patients with opioid and cannabis dependence perform poorly compared with those with opioid dependence alone. METHODS: We recruited three groups of participants aged 18 to 55 years: opioid and cannabis dependence (OCaD; n = 21), only opioid dependence (OD; n = 19), and a control group (HC; n = 20). Subjects with other substance use, human immunodeficiency virus, head injury, epilepsy, and severe mental illness were excluded. Cognitive tests, performed after at least 1 week of abstinence, consisted of the Wisconsin card sorting test (WCST), Iowa gambling task (IGT), trail making tests A and B (TMT-A and B), verbal and visual N-back test (NBT), and standard progressive matrices for intelligence quotient (IQ). The general linear model was used to compare the groups with age and years of education as covariates. RESULTS: IQ and severity of opioid dependence were comparable in the three groups. The mean duration of cannabis use was 76.2 (±39.4) months. Compared with the HC, both OD and OCaD had significant impairment on the IGT, WCST, TMTs, and NBT. No significant group difference was observed between the OD and OCaD groups. DISCUSSION AND CONCLUSIONS: Opioid dependence is associated with impairments in decision making, executive function, working memory, and attention. Co-morbid cannabis dependence had similar profiles of cognitive impairments. SCIENTIFIC SIGNIFICANCE: Co-morbid cannabis dependence might not add on to the existing cognitive dysfunction in opioid dependence. Further studies should be done with a larger sample.

BACKGROUND: The COVID-19 pandemic has affected the availability and access to medications for opioid dependence (OD). We examined the monthly trends in new buprenorphine/naloxone (BNX) treatment episodes, number of clinical visits for BNX, BNX dispensed per person, and BNX prescription over 56-month, which included pre-pandemic, during early, and later part of pandemic (Jan 2017 - Aug 2022). METHODS: Research data were collected from the pharmacy database of a large publicly funded treatment center in India. A flexible, low-threshold service was adopted in April 2020 in response to the lockdown implemented on 25 March 2020. Change Point analyses were performed to examine monthly trends visually and statistically. We used Autoregressive integrated moving averages to forecast trends from April to Aug 2020 and March to August 2022, using Jan 2017 to March 2020 and March 2020 to February 2022 as training datasets. RESULTS: 993 patients were started on BNX treatment, 40452 BNX clinic attendances were made, 1401393 BNX tablets were dispensed, and 6795 new patients with OD were registered. The observed data for clinic attendance for BNX was significantly lower than the projected estimates in April -Aug 2020; however, observed new treatment episodes and monthly BNX prescriptions were within the 95% projected estimates; BNX dispensed per person was significantly more than the projected estimate. In contrast, observed BNX prescription trends surpassed the upper limit of 95% CI in March-Aug 2022. CONCLUSION: A low-threshold and flexible treatment service could mitigate the unintended consequences of pandemic-induced restrictions.
RESUMO
BACKGROUND: There is limited on the risk factors and mortality in patients with delirium from India. AIM: This study aimed to evaluate the risk factors associated with delirium and inpatient mortality rates of patients diagnosed with delirium by psychiatry consultation liaison services. MATERIALS AND METHODS: Three hundred and thirty-one patients diagnosed as delirium by the psychiatry consultation liaison services were examined on standardized instruments: Delirium Rating Scale Revised 98 version (DRS-R-98), amended Delirium Motor Symptom Scale (DMSS), Delirium Etiology Checklist (DEC), Charlson Comorbidity index, and a checklist for assessment of risk factors. RESULTS: More than three medications as a risk factor and metabolic/endocrine disturbances as cause were observed to play largest role in development of delirium. The inpatient mortality rate was 12.4%. Compared to the survivor group, those who died were more likely to be young (<65 years), had significantly high rate of alcohol dependence and were more frequently restrained prior to development of delirium; of these only age <65 years and use of restraints emerged as the significant predictors of mortality in regression analysis. CONCLUSION: Age and use of restraints appears to be an important predictor mortality in patients with delirium.

We aimed to examine whether treatment retention, abstinence, and adherence to buprenorphine-naloxone (BNX) differ among individuals with opioid dependence (OD) across three common categories of opioids- heroin, opium, and low-potency pharmaceutical. In a retrospective cohort study, we analyzed outpatient treatment records from March 2020 through February 2022. Opioid category was determined by lifetime and current opioid use. We defined treatment retention as weeks of uninterrupted clinic attendance. Abstinence and BNX adherence were calculated by weeks of extra-medical opioid-negative and buprenorphine-positive urine screening from treatment initiation. Four-hundred-thirteen patients were eligible; 406 (98.3%) were included in the final analysis. Two-hundred-ninety (71.4%) patients were dependent on heroin; 66 (16.3%) were natural opioid dependent, and 50 (12.3%) were dependent on low-potency pharmaceutical opioids. BNX effectiveness in treatment retention, abstinence, and adherence did not differ in patients dependent on heroin, natural, and low-potency pharmaceutical opioids. Patients on ≥8 mg daily BNX had better retention and adherence than those on <8 mg daily. Patients from lower socioeconomic status (SES) had higher odds of retention, abstinence, and adherence than those from upper/middle SES. Treatment outcomes on BNX did not differ across opioid categories. However, BNX should be dosed adequately.
RESUMO
Background Opioid use disorder (OUD), a relapsing-remitting chronic medical disease, accounts for a sizable proportion of all-cause adult inpatient stays. We evaluated the incidence and predictors of any and multiple readmissions to inpatient care for OUD. Methods This retrospective, register-based cohort study assessed consecutive patients with OUD admitted to a federally-funded inpatient service of an addiction treatment center in North India between January 2007 and December 2014. Binary logistic regression was used to determine independent readmission predictors based on demographic, clinical, and treatment variables that significantly differed in bivariate analysis. Results Among 908 patients, 306 (33.7%) and 106 (11.7%) had any and multiple readmissions, respectively. Injection drug use (Odds ratio [OR] 2.92, 95% confidence interval [CI] 1.90-4.49), comorbid severe mental illness (OR 2.80, 95% CI 1.42-5.55) and common mental disorder (OR 3.4 95% CI 1.65-6.95), antagonist treatment (OR 1.6 95% CI 1.14-2.27), and urban residence (OR 1.38 95% CI 1.01-1.90) increased odds of readmission. 'Improved' discharge status (OR 0.48 95% CI 0.34-0.70) in first admissions reduced odds of any readmission. Similar risk factors also influenced multiple readmissions with higher odds ratios. Conclusions Identification and adequate treatment of risk factors may reduce the chances of readmission.

INTRODUCTION: Treatment completion is associated with a better outcome in substance use disorders. We examined the rates of treatment completion and its predictors in patients admitted to specialized addiction treatment settings over a 13-year period. METHODS: Ours was a retrospective cohort study. We included consecutive 2850 patients admitted to the inpatient treatment between January 2007 and December 2019. We divided the patients into 2 groups: completed versus premature discontinuation of treatment. The predictor variables were based on previous research, clinical experience, and availability of the digital record. RESULTS: The number of patients who completed and discontinued treatments was 1873 (72.6%) and 707 (27.4%), respectively. The inpatient treatment discontinuation rate varied widely during the study period (18% in 2007 and 41% in 2012). The average rate of treatment discontinuation was 27%. The change-point analysis showed 5 statistically significant change points in the years 2008, 2010, 2012, 2014, and 2016. Patients who were prescribed medications for alcohol and opioid dependence and those who were on opioid agonist treatment had 4.7 and 6.3 higher odds of completing inpatient treatment than those who were not on medication. Patients with physical and psychiatric comorbidities had higher odds of treatment completion. Patients with a primary diagnosis of opioid dependence had lower odds of treatment completion than those with alcohol dependence. CONCLUSIONS: The rates of discontinuation may vary with concurrent changes in the treatment policies. Awareness of the risk factors and policy measures that may improve treatment completion must aid in informed decision making.

We report the observation of electron-temperature-gradient (ETG) driven turbulence in the laboratory plasma of a large volume plasma device. The removal of unutilized primary ionizing and nonthermal electrons from uniform density plasma and the imposition and control of the gradient in the electron temperature (T[Symbol: see text] T(e)) are all achieved by placing a large (2 m diameter) magnetic electron energy filter in the middle of the device. In the dressed plasma, the observed ETG turbulence in the lower hybrid range of frequencies ν = (1-80 kHz) is characterized by a broadband with a power law. The mean wave number k perpendicular ρ(e) = (0.1-0.2) satisfies the condition k perpendicular ρ(e) ≤ 1, where ρ(e) is the electron Larmor radius.
RESUMO
Background: Individuals with opioid dependence experience stigma and discrimination. Stigma can potentially reduce treatment-seeking and negatively affect treatment outcomes. We aimed to study the course of stigma and its correlates among patients receiving opioid agonist treatment (OAT). Methods: We recruited 51 subjects (aged between 18 and 45 years) registered in the OAT clinic from February to September 2019. We excluded subjects dependent on alcohol and other drugs (except for cannabis and tobacco), with severe mental illness, intellectual disability, and organic brain disease. We assessed the internalized and enacted stigma and quality of life at the treatment entry and after 3 months. Relationship of stigma with quality of life, socio-demographic, and other clinical variables were examined at the treatment entry. Results: Mean age of the subjects was 26.7 (± 5) years. At the end of three months, 33 (64.7%) patients were retained in the treatment. Internalized stigma correlated negatively with the social and environmental domains of quality of life. The strength of the correlations was modest. No significant correlation was found between demographic and clinical variables and internalized stigma and enacted stigma scores. Both internalized and enacted stigma scores reduced significantly at 3 months follow-up. The significance levels were retained even after controlling for the baseline quality of life scores. Stigma at the treatment entry did not predict early dropout. Conclusion: Despite higher severity at the treatment entry, the level of internalized and enacted stigma reduced significantly within three months of an outpatient-based OAT program.
RESUMO
Media provides and shapes public knowledge, perceptions, and attitude towards people with substance misuse. We aimed to explore the content and specific themes of Indian online news articles on substance use or persons with substance misuse. We followed an exploratory qualitative design to analyze online news media reports published between July 1 2020 and June 30 2021. Hundred articles met the selection criteria. Our content analysis was based on a checklist. Thematic analysis was done by the coding, categorization, and theme generation after meticulous data immersion and triangulation. Sixty percent of articles had pessimistic headlines and portrayed substance use or persons with substance use negatively. Fifty-one percent articles were on alcohol. Twenty-seven percent articles focussed supply reduction, whereas only 5% positively discussed the role of treatment. We identified seven themes. Most frequent themes were legal-criminal aspects of substance use (n = 39), psychosocial and health hazards of substance use (n = 30), and propagation of public stigma (n = 25). Two other prevalent themes were the business and marketing of alcohol (n = 20) and sociocultural aspects of substance use (n = 9). The theme, treatment strategy, appeared in only five articles. There is an urgent need for media guidelines for responsible reporting of substance misuse. We suggested a set of recommendations for media reporting.
RESUMO
Delirium is characterized by disturbances of consciousness, attention, cognition, perception, emotions, sleep, and psychomotor activity. Management of delirium involves ensuring safety, improving functioning, identifying and treating the illness underlying the delirium, and use of antipsychotics or benzodiazepines to control behavioural symptoms and prevent mortality. Haloperidol continues to be the most commonly used antipsychotic in delirium. However, in recent times data have emerged which suggest that atypical antipsychotics may be as efficacious as haloperidol in the treatment of delirium. This review intends to review the data with respect to usefulness of atypical antipsychotics in the treatment of delirium. Besides atypical antipsychotics, data with respect to another group of medications - cholinesterase inhibitors are also reviewed. Electronic and manual searches were conducted to identify all the relevant studies and case reports/case series. Evidence suggests that risperidone, olanzapine and quetiapine are as efficacious as haloperidol in the treatment of delirium but have lesser side effects. Data for other atypical antipsychotics are scarce. The data on cholinesterase inhibitors for treatment and prevention of delirium are beginning to accumulate, but do not seem to be convincing. Our review suggests that risperidone, olanzapine and quetiapine are good alternatives to haloperidol in the treatment of delirium.

Restricted access to healthcare during COVID-19 pandemic warranted an urgent adaptation of telemedicine practice. We describe a synchronous, stepwise (telephonic, video, and in-person consultation) direct-care model. From 18th May to 31st August 2020, 128 new and 198 follow-up patients received consultation. Eighty-nine percent of new patients required video-consultation. Sixty-eight percent of follow-up cases were managed by telephonic consultation. A third of new and a fifth of the follow-up patients had to be called for physical consultation. Limited access to and understanding of the technologies, potential breach in privacy, and restrictions imposed on online prescription of medications posed significant challenges.

Coronavirus disease 2019 (COVID-19) has been declared as a pandemic by the World Health Organization on March 11, 2020. It has affected most countries of the world, including India. Both the disease and the unavoidable national response to it have posed unique challenges to our health-care system. A particular vulnerable group of patients is those with opioid dependence maintained on opioid substitution therapy (OST). These patients are pharmacologically dependent on the OST medication (buprenorphine, buprenorphine-naloxone combination [BNX], and methadone) for their healthy functioning and recovery. COVID-19 outbreak, lock-down, and difficult access to medical care, all are likely to induce stress and withdrawal, which is a potential risk for relapse among individuals with opioid dependence, who are anyway more vulnerable due to social, housing, living, and medical conditions. In this context, it is essential to re-strategize the existing OST services to adapt to the challenging circumstances. In this communication, we share our experience and formulate interim standard operating procedures (SOPs) for running a hospital-based OST service utilizing take-home BNX. The challenges, principles to meet the challenges, and interim SOPs are shared as being currently practiced in our center. Individual institutes, agencies, hospitals, and clinics running OST service with BNX can adapt these SOPs according to their characteristics, needs, demand, and resources; so long as, the basic principles are adhered to.
RESUMO
BACKGROUND AND OBJECTIVES: Large-scale prospective case series of tapentadol abuse or dependence in India is not available. Hence, we aimed to study the prevalence and profile of tapentadol users in a treatment-seeking population. MATERIALS AND METHODS: The study had prospective and retrospective arms. We collected 8-month prospective data by face-to-face interviews (n = 70) and 8-year retrospective data from case notes (n = 26) with either tapentadol misuse/abuse or dependence in patients attending a de-addiction center. RESULTS: The prevalence of tapentadol abuse or dependence was 25% among the pharmaceutical opioid users. Concurrent use of other opioids was seen in >80% of participants of both the arms. Major sources of tapentadol were chemists (without a prescription) (53%) and doctors (prescriptions) (40%). Patients in the tapentadol dependence group had a significantly higher dose, duration, and pharmaceutical opioid use. CONCLUSION: India needs awareness promotion, training, availability restriction, and provision of treatment for tapentadol abuse or dependence.
RESUMO
OBJECTIVES: Since 25th March 2020 India went into a complete and extended lockdown. Alcohol production, sales, and purchase were barred with this overnight prohibition order. We conducted a qualitative analysis of the media reports published within the first month of the nationwide lockdown with the objectives (a) using the media reports as indications of possible public health impact and population response of a sudden alcohol prohibition in India, (b) suggesting areas for future research. METHODS: We performed thematic and content analysis of 350 articles published online in national newspapers between the 26th March, 2020 and 25th April, 2020. Initial inductive, followed by deductive coding was done in this exploratory thematic analysis. RESULTS: The thematic analysis revealed four main themes: the beneficial aspects of the policy, the harmful aspects of the policy, non-compliance and attempts to change and / or subvert the policy, popularity and level of public buy-in of the policy. We generated relevant sub-themes under main themes. Two additional themes, not directly related to the sudden prohibition, were use of stigmatizing language and ethical concerns. The content analysis showed the frequency of the appearance of the main themes and proportions of sub-themes and codes under those main themes. CONCLUSION: The harms, perceived from the media reports, should be balanced against the potential benefits. Absence of a national-level alcohol policy was made apparent by the reflexive, disconnected, and conflictual measures. Future research could systematically examine the potential ramifications of alcohol prohibition on public health, social, and economic aspects.

BACKGROUND & OBJECTIVE: Relapse is a common and distressing aspect of substance dependence mediated by several biological and psychosocial factors. This study examined the association between demographic variables, clinical parameters and certain psychosocial factors and relapse among patients with either alcohol or opioid dependence. METHODS: Structured assessments of clinical/demographic parameters, relapse precipitants, coping strategies, self-efficacy, stressful life events and perceived social support were carried out among patients with alcohol/opoid dependence (n=30) who had relapsed and compared with those (n=30) who had managed to remain abstinent. Similar comparisons were also carried out between relapsed and abstinent patients in the individual subgroups of alcohol and opioid dependence. RESULTS: Patients who had relapsed were significantly more likely (i) to have a positive family history of substance use and higher number of previous relapses; (ii) to be using maladaptive coping strategies; (iii) to have been exposed to a higher total number of 'high risk' situations; and (iv) have experienced a higher number of undesirable life events. Those who had remained abstinent tended to use significantly more number of coping strategies, principally adaptive ones and scored significantly higher on all measures of self-efficacy. Factors influencing relapse appeared to be largely similar among patients with alcohol and opioid dependence. INTERPRETATION & CONCLUSION: This study provided further evidence in support of the importance of certain clinical/psychosocial factors in relapse in substance dependence. It extended these results to substances other than alcohol and provides the basis for investigating correlates of relapse in a wide range of behavioural and substance use problems.

This paper describes 5 kA, 12 ms pulsed power supply for inductive load of Electron Energy Filter (EEF) in large volume plasma device. The power supply is based upon the principle of rapid sourcing of energy from the capacitor bank (2.8 F/200 V) by using a static switch, comprising of ten Insulated Gate Bipolar Transistors (IGBTs). A suitable mechanism is developed to ensure equal sharing of current and uniform power distribution during the operation of these IGBTs. Safe commutation of power to the EEF is ensured by the proper optimization of its components and by the introduction of over voltage protection (>6 kV) using an indigenously designed snubber circuit. Various time sequences relevant to different actions of power supply, viz., pulse width control and repetition rate, are realized through optically isolated computer controlled interface.
