The objective of the study was to assess the levels of neutralizing antibody after COVID vaccination in the elderly and compare it with that of the younger persons. The study also aimed at determining the association between the age, sex, and comorbidities and levels of neutralizing antibodies in the young and the old. Subjects and Methods: This was a single-center, cross-sectional, analytical study, conducted in the General Medicine Unit of ACS Medical College, Chennai, from August 2021 to October 2021. Forty‑five elderly persons aged 60 years and above and 103 young adults aged 18 years and above and <60 years who were vaccinated with either COVISHIELD or COVAXIN were randomly selected to participate in this study. A detailed history regarding vaccination status, vaccination type, comorbidities, and breakthrough infection was obtained. Blood samples were collected from the participants to analyze the levels of neutralizing antibodies developed after COVID vaccination. Results: The mean age of the older participants was 66.13 ± 5.3 years and the mean age of the younger participants was 36.48 ± 10.9 years. The median level of neutralizing antibody in the younger participants was 97.4% (interquartile range [IQR]: 96.4%–98.0%) and in the older participants was 97.1% (IQR: 93.1%–97.6%). There was a significant difference in the neutralizing antibody level between the younger and the older participants (P = 0.033). There was no significant difference in the neutralizing antibody levels after two doses of either of the two vaccines among both the groups of participants. There was no significant association between the neutralizing antibody titer and sex and comorbidities in both the groups of participants. Five young and two old participants had breakthrough infections after vaccination. The antibody level was higher in persons with breakthrough infection than in those with no breakthrough infection in both the study groups. Conclusion: There was a significant difference in the neutralizing antibody level between the younger and the older participants after COVID vaccination. No significant difference existed in neutralizing antibody response with respect to the type of vaccine in both the study groups. There was no significant association between sex, comorbid status, and neutralizing antibody levels in both the groups. [ABSTRACT FROM AUTHOR]

Hydrazides, N-N containing structural motifs, are important due to their presence in a wide variety of biologically significant compounds. While the homo N-N coupling of two NH moieties to form the hydrazide N-N bond is well developed, the cross-dehydrogenative hetero N-N coupling remains very unevolved. Here we present an efficient intermolecular N-N cross-coupling of a series of primary benzamides with broad range of Lewis basic primary and secondary amines using PhI(OAc) 2 as both a terminal oxidant and a cross-coupling mediator, without the need for metal catalysts, high temperatures, and inert atmospheres, and with substantial potential for use in the late-stage functionalization of drugs., (© 2024.

Background: One-third of people living with HIV (PLHIV) have alcohol misuse or alcohol use disorders which negatively affect course and outcome of HIV. Objectives: The meta-analysis sought to evaluate the effectiveness of brief interventions (BI) on alcohol and HIV outcomes in PLHIV with alcohol misuse. Methods: We included clinical trials published between 1990 and September 2022 on adults with harmful/hazardous alcohol use; only randomized clinical trials (RCTs) were included in the meta-analysis. We searched MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Clinical Trials.Gov, and the World Health Organization's International Clinical Trials Registry Platform databases. Cochrane's risk-of-bias assessment was used. Results: Eighteen studies were included in the narrative synthesis, and a meta-analysis could be performed on 13 studies. Among the included RCTs, seven showed a low risk and two showed a high risk of bias; others showed some concerns. There was no evidence of publication bias. Compared to the control, BI significantly reduces the drinks per drinking day ( N  = 5, Hedge's g= -0.45, 95%CI = -0.58, -0.32) and the number of heavy drinking days ( N  = 4, Hedge'sg = -0.81, 95% CI= -0.94, -0.67) between 3-6 months post-intervention. BI also reduces the odds of mortality by 42% ( N  = 7, OR = 0.58, 95% CI = 0.34, 0.99) in 6-12 months. BI does not change the alcohol risk scores and transition to harmful alcohol use; it does not improve adherence to Anti-Retroviral Therapy and increase viral suppression. Conclusion: Policymakers must introduce and scale up integrated screening and brief intervention services within HIV clinics and primary care.

Background: Acute and transient psychotic disorder (ATPD) was recognized as separate from other psychotic disorders and described in the International Classification of Diseases (ICD) tenth revision for the first time. A lot of research on ATPD has been conducted in India over the last six decades, but a review focusing exclusively on Indian research on ATPD is not available., Aim: This paper aims to review the literature on ATPD emerging from India., Methodology: A combination of search terms "Acute and Transient Psychosis," "acute psychosis," "non-affective psychosis," "non-affective psychotic disorder," "reactive psychosis," "first-episode psychosis," and "India" were searched on various search engines like PUBMED, Medknow, Hinari, and Google Scholar. We also did a hand search for additional relevant articles, including published abstracts of the Indian Journal of Psychiatry from 2007 to 2023. Relevant papers were selected., Results: The prevalence of ATPD varies across different study settings, and it tends to have an abrupt to acute onset, and is primarily associated with stress. Few studies have assessed the subtypes of ATPD, and symptom profile has been inconsistently reported. There is a lack of trials on the effectiveness or efficacy of antipsychotics in ATPD patients. In a large proportion of patients initially diagnosed with ATPD, the diagnosis remains stable, with recurrence varying from 10% to 46.6% based on the duration of follow-up., Conclusion: There is a need for more multicentric studies, studies with larger sample sizes, and consistency in data about risk factors. There is a need to evaluate symptom profile, course, outcome, and treatment outcomes in patients with ATPD using validated instruments to improve our understanding. Further, there is a need for comparative studies to evaluate the risk factors for ATPD., Competing Interests: There are no conflicts of interest., (Copyright: © 2023 Indian Journal of Psychiatry.)

Background: There is a lack of data on the use of continuation electroconvulsive therapy (C-ECT) from India., Objectives: This study aimed to evaluate the clinical profile and outcome of patients receiving C-ECT., Materials and Methods: The ECT register was used to identify patients receiving C-ECT (ECT after completion of an acute course, to maintain remission or prevent relapse) from 2011 to July 2022. Socio-demographic, clinical, and treatment outcome details were extracted from their treatment records., Results: A total of 72 C-ECT courses were identified that were used in 60 patients. Out of all the patients receiving ECT, only 3.25% of patients receive C-ECT. The majority of the patients were male (60%). The mean age of the patients at the time of starting ECT was around 39 years. The most common diagnosis was schizophrenia (73.3%), followed by recurrent depressive disorder (21.6%). The most common indication was persistent psychotic symptoms poorly responding to multiple antipsychotic trials of 3.09 (SD: 1.39), including clozapine. These patients received a mean of 22.58 (SD: 8.05; range: 10 to 46) ECTs, with 10.0 (SD: 4.83) ECTs for the management of the acute phase of illness and 12.57 (SD: 6.20) ECTs as part of continuation treatment. The majority (61.1%) of the patients received four (once weekly) C-ECTs in the first month, followed by three more in the next month. However, 16 patients received weekly ECTs during the second month too, as symptoms worsened with the lowering of frequencies. Twelve patients received more than one C-ECT course. The majority of the patients maintained the improvement gained during the acute phase or showed further improvement with C-ECT along with ongoing pharmacotherapy as rated on appropriate scales. The Clinical Global Impressions-Severity (CGI-S) difference before and after C-ECTs was 2.94 (SD: 0.88)., Conclusions: C-ECT is considered in only in a small proportion of patients. However, when used, it is effective in maintaining the benefits gained during the acute course of ECT and preventing relapse., Competing Interests: There are no conflicts of interest., (Copyright: © 2023 Indian Journal of Psychiatry.)

Pyrazole and its derivatives are important azole heteroarenes prevalent in pharmaceutical compounds and have been used as ligands for protein binding, making them valuable targets for synthetic applications. Herein we disclose an electrochemical intermolecular C-H/N-H oxidative annulation of 2-phenylpyrazoles with alkynes using a rhodium(III) redox regime without any external metal oxidants in a water compatible solvent system. Both symmetrical and unsymmetrical alkynes were shown to be compatible with the optimized conditions.

Background and Aims: Multiple substance use is a common but underrecognized problem in patients on opioid agonist treatment (OAT). Co-occurring substance misuse is associated with poor clinical and psychosocial outcomes. We aimed ( a ) to determine the effect of screening and brief intervention (SBI) for substance misuse in people on OAT and (b) to qualitatively summarize the implementation of SBI., Methods: We performed a systematic review of clinical trials on the efficacy of SBI for alcohol and drug misuse in participants on OAT. We searched 5 electronic databases and included published studies and unpublished trials. We measured the standardized mean difference in substance risk scores before and after intervention. We also estimated the standardized mean difference in alcohol consumption per day before and after intervention., Results: We included a total of 8 studies; 5 of these were included in the meta-analysis, and all were reviewed for narrative synthesis. We observed a significant change in the pre-post brief intervention substance risk scores with a medium effect size (Hedges g = 0.752, 95% confidence interval, 0.405-1.099). Sensitivity analyses with different pretest-posttest correlations did not change our result. Modest effects of SBI were found in reducing both alcohol and illicit drug risk scores, and among the population on methadone and buprenorphine treatment. We also observed a significant decrease in alcohol consumption per day 3 months after SBI. Studies showed a limited and incomplete screening for substance misuse and delivery of brief intervention in OAT settings., Conclusions: Screening and brief intervention may be a potential treatment for co-occurring substance misuse among patients on OAT., Competing Interests: The authors report no conflicts of interest., (Copyright © 2022 American Society of Addiction Medicine.)

The regiochemical outcome of a cobalt(II) catalysed C-H activation reaction of aminoquinoline benzamides with unsymmetrical 1,3-diynes under relatively mild reaction conditions can be steered through the choice of diyne. The choice of diyne provides access to either 3- or 4-hydroxyalkyl isoquinolinones, paving the way for the synthesis of more highly elaborate isoquinolines.

Background: The existing literature indicates that psychotherapeutic treatment, especially exposure and response prevention (ERP) is efficacious in treating obsessive-compulsive disorder (OCD). The coronavirus disease 2019 pandemic adversely impacted many patients with OCD and disrupted their usual treatment. Moreover, the pandemic forced a global switch to telemental health (TMH) services to maintain the standards and continuity of care. Consequently, clinicians are increasingly using TMH-based psychotherapeutic treatments to treat OCD. However, several challenges have made it difficult for them to implement these treatments in the changed circumstances imposed by the pandemic., Aim: To describe the formulation, implementation, feasibility, and usefulness of videoconferencing-based ERP (VC-ERP) treatment for OCD during the coronavirus disease 2019 pandemic., Methods: This prospective, observational study was conducted in the psychiatric unit of a multi-specialty hospital in north India over 12 mo (July 2020-June 2021). All patients with OCD were assessed using the home-based TMH services of the department. The VC-ERP protocol for OCD was the outcome of weekly Zoom meetings with a group of clinicians involved in administering the treatment. After a systematic evaluation of the available treatment options, an initial protocol for delivering VC-ERP was developed. Guidelines for clinicians and educational materials for patients and their families were prepared. The protocol was implemented among patients with OCD attending the TMH services, and their progress was monitored. The weekly meetings were used to upgrade the protocol to meet the needs of all stakeholders. Feasibility and efficacy outcomes were examined., Results: All patients were diagnosed with OCD as a primary or a comorbid condition according to the International Classification of Diseases, 10 th version criteria. Out of 115 patients who attended the services during the study period, 37 were excluded from the final analysis. Of the remaining 78 patients, VC-ERP was initiated in 43 patients. Six patients dropped out, and three were hospitalized for inpatient ERP. Eleven patients have completed the full VC-ERP treatment. One patient completed the psychoeducation part of the protocol. VC-ERP is ongoing in 22 patients. The protocol for VC-ERP treatment was developed and upgraded online. A large proportion of the eligible patients ( n = 34/43; 79%) actively engaged in the VC-ERP treatment. Drop-out rates were low ( n = 6/43; 14%). Satisfaction with the treatment was adequate among patients, caregivers, and clinicians. Apart from hospitalization in 3 patients, there were no other adverse events. Hybrid care and stepped care approaches could be incorporated into the VC-ERP protocol. Therefore, the feasibility of VC-ERP treatment in terms of operational viability, service utilization, service engagement, need for additional in-person services, frequency of adverse events, and user satisfaction was adequate. The VC-ERP treatment was found to be efficacious in the 11 patients who had completed the full treatment. Significant reductions in symptoms and maintenance of treatment gains on follow-up were observed., Conclusion: This study provided preliminary evidence for the feasibility and usefulness of VC-ERP in the treatment of OCD. The results suggest that VC-ERP can be a useful option in resource-constrained settings., Competing Interests: Conflict-of-interest statement: None of the authors have any potential conflicts of interest to report.

Background: Although clozapine is much researched in western literature, a review on Indian research on clozapine published in 2010 reported limited data and need for further research in this area., Aim: We aimed to conduct a systematic review of research on clozapine from India from 2010 to mid-2022 and also compare the same with research output before 2010., Methodology: A systematic various search engines, i.e., PUBMED, Medknow, Hinari and Google Scholar was done using the key words clozapine and India. Published articles with clozapine in the title and having an author from India, published during 2010 to July 2022 were included., Results: Initial Internet and hand searches yielded 280 articles, out of which 126 articles were excluded due to various reasons and 154 articles, were included for the review. This included 84 case reports, 49 original articles, 11 review articles and 10 letters to the editor as comments. We found an increase in the number of publications during the period of 2010-2022 compared to 1997-2009 in all types of publications. Over the years a significant proportion of the articles focused on various side effects of clozapine, factors associated with response and non-response to clozapine and evaluation of outcomes other than efficacy/effectiveness. However, all the studies were limited to a single centre with no multicentric studies on clozapine., Conclusion: Over the last 12 years or so, there is increase in the number of publications on clozapine. However, there is lack of multicentric studies., Competing Interests: Conflict of interest None., (Copyright © 2022 Elsevier B.V. All rights reserved.)

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: Substance use may affect sexual functioning in both men and women. Comorbid sexual dysfunction adds to the clinical burden of substance use disorders (SUD)., Aims: The broad aims were to identify research conduct, types of the available evidence, and research gaps in (i) estimating the incidence, prevalence, type, and severity of sexual dysfunction in adults with SUD; (ii) exploring correlates of sexual dysfunction in SUD., Methods: We conducted systematic searches on PubMed, Google Scholar, and Embase for studies published in the English language between August 1954 and November 2020. We included prospective and cross-sectional observational studies that had examined the prevalence or incidence of any sexual dysfunction in adults of either gender with substance use disorders. Review articles and those with an exclusive focus on tobacco use disorders were excluded. The review was registered in PROSPERO., Results: Our search identified 65 relevant articles, including five prospective studies. All the prospective studies and most of the cross-sectional studies (n = 40) were done among men and subjects with alcohol (n = 20) and opioid (n = 23) use disorders in clinical populations. Substance use and sexual dysfunction were assessed by a wide range of instruments. Prospective studies reported a prevalence of sexual dysfunction at 75% and 61% for alcohol and opioid use disorders, respectively. The prevalence of any sexual dysfunction in cross-sectional studies ranged between 15 and 100 percent. Erectile dysfunction was the most commonly studied and observed sexual dysfunction. Comorbidity and socioeconomic deprivation were consistently associated with a higher occurrence of sexual dysfunctions., Strengths: We did not limit our review by the type of substances and year of publication. We adhered to the standards of conducting and reporting scoping reviews; hence, our review results should be replicable, transparent, and reliable., Limitations: The wide clinical and methodological heterogeneity precluded a systematic review., Conclusion: Research gaps exist in women, non-clinical population, stimulants, and cannabis use disorders, and effect of treatment of SUD in sexual functioning. The quality of evidence is poor. Ghosh A, Kathiravan S, Sharma K, Mattoo SK. A Scoping Review of the Prevalence and Correlates of Sexual Dysfunction in Adults With Substance use Disorders.

Objectives: Physicians across the world have been disproportionately affected by the COVID-19 pandemic. This study was designed and conducted to assess the emotional and behavioural reactions of physicians to the initial phase of the COVID-19 pandemic., Subjects and Methods: An online survey questionnaire using the google forms platform was constructed by the authors. The items in the questionnaire were based on clinical experience, relevant literature review and discussion with peers. A list of issues that were deemed as essential components of the experience of the pandemic relevant to physicians was arrived at. Thereafter these issues were operationalized into question form and hosted on the google forms platform. The link to this questionnaire was circulated by the authors among their peer groups in the month of April 2020., Results: We received 295 responses and 3 were unusable. Most of the responses were from India, the United States of America, Australia, Canada and the United Kingdom. About 60% of the respondents identified themselves as frontline and had a decade of clinical experience. Most respondents reported being anxious due to the pandemic and also observed the same in their peers and families. A majority also observed changes in behaviour in self and others and advanced a variety of reasons and concerns. A sense of duty was the most commonly employed coping mechanism., Conclusion: Physicians are not immune from information and misinformation, or cues in the environment. Behavioural choices are not always predicted by knowledge but by a combination of knowledge, emotional state, personality and environment. Healthcare settings need to be ready for emergencies and should focus on reducing uncertainty in physicians. These factors may also be gainfully used in the mental health promotion of physicians in COVID-19 care roles.

Background: COVID-19 pandemic is the first modern pandemic and has occurred in an era of social media ubiquity. Despite being in stage 1 of the pandemic, and low numbers of patients, various emotional and behavioral changes were observed in junior doctors. This study was designed to assess the experience and reactions of junior doctors in a tertiary teaching hospital in North India and Tamil Nadu in the immediate aftermath of the nation-wide lockdown., Subjects and Methods: This was an observational cross- sectional study of junior doctors working in tertiary care hospitals in Chandigarh and Tamil Nadu. It was conducted from 28 th March to 5 th April 2020. Ethical clearance obtained and anonymity was maintained. We used a 17-item self-designed questionnaire circulated online., Results: Mean age was 28.64 years (n=362). Though mostly well informed, only 8% restricted themselves to obtaining information from a single source. Around 46% were feeling anxious and many more (73.20%) perceived the same emotion in their peers and even more of them (85.10%) in their family members. Most of them (90.1%) endorsed more than change in behavior, mainly to avoid potential risk (52%) and females tend to self-quarantine themselves more than males., Conclusions: Knowledge does not play as important a role in the way people behave in an outbreak. Many other covert factors may possible be involved. Strategies leading to reduction in uncertainty, interventions for reassurance in the workplace and better role models would be of help in this outbreak.
