Cognitive remediation and schizophrenia: Effects on brain complexity.

The objective of this study is to investigate nonlinear neural dynamics of chronic patients with schizophrenia following 3 months of cognitive remediation and to find correlations with neuropsychological measures of cognition. Twenty nine patients were randomized to Cognitive Training (CT) and Treatment as Usual (TAU) group. The system complexity is estimated by Correlation Dimension (D2) and Largest Lyapunov Exponent (LLE) from the reconstructed attractor of the underlying system. Significant increase in dimensional complexity (D2) over time is observed in prefrontal and medial frontal-central regions in eyes open and arithmetic condition; and posterior parietal-occipital region under eyes closed after 3 months. Dynamical complexity (LLE) significantly decreased over time in medial left central region under eyes closed and eyes open condition; prefrontal region in eyes open and lateral right temporal region in arithmetic condition. Interaction is significant for medial left central region with TAU group exhibiting greater decrease in LLE compared to CT group. The CT group showed significant correlation of increased D2 with focused attention. In this study it is found that patients with schizophrenia exhibit higher dimensional and lower dynamical complexity over time indicating improvement in neurodynamics of underlying physiological system.

Psychiatric morbidity and substance use in migrant workers: A population based study.

BACKGROUND: The prevalence of mental health problems and substance abuse in the migrant population is higher than the general population. AIMS AND OBJECTIVES: To assess the prevalence and pattern of mental health issues and substance use in the migrant population and highlight the association with the reverse migration of migrant workers. METHODOLOGY: The field staff visited the shelter homes for migrant population in four cities of Northern India (Chandigarh (UT), Bhatinda (Punjab), Panchkula (Haryana) and Jaipur (Rajasthan). After maintaining the social distance and wearing masks by the staff and migrants, written informed consent was taken for participation in the study. The socio-demographic details of reverse migrants were noted down and Hindi version of Patient Health Questionnaire (PHQ-9) for mental health problems and screening tool for pattern of substance abuse was administered. Geographically matched undisplaced were also administered these tools. RESULTS: A total of 275 reverse migrants and 276 undisplaced were included in the study. The prevalence of ever use for all the substances among reverse migrants was 44.4% (122/275) and among undisplaced, it was 45.3%. The prevalence of alcohol, tobacco and cannabis was higher than the general population. The prevalence of at least one diagnosis on PHQ-9 is 13.45% (reverse migrants 19.3% and undisplaced 7.6) and the prevalence of other depressive disorder is significantly higher in reverse migrants (17.1%) than undisplaced (4.0%). CONCLUSION: The study concludes that prevalence of mental health issues and substance abuse in migrant population is significantly higher than the general population and the prevalence of at least one diagnosis and other depressive disorder is significantly higher in reverse migrants than undisplaced.

Psychosocial intervention model for migrant workers during extended lockdown: The Chandigarh model.

BACKGROUND: Human suffering and future uncertainty due to extended lockdown is enormous and this is much more among migrant workers. AIM: The aim of this study was to design and utilize a model for psychosocial intervention for migrant workers during the extended lockdown. MATERIALS AND METHODS: In Chandigarh, due to lockdown, 61 migrant workers from various states were lodged in a shelter home at village Maloya, located in the outskirt of Chandigarh. Since no specific model was available to handle the psychosocial issues of this specific population, hence, an attempt was made to prepare a model for psychosocial intervention using Maslow's hierarchy of needs. RESULTS: Changes in infrastructure and facilities provided to migrant workers due to implementation of this model for psychosocial intervention helped the participants seeing beyond their problems. CONCLUSION: Psychosocial intervention model based on Maslow's theory was found suitable for migrant workers in shelter home in Chandigarh.

Factors Leading to Reverse Migration Among Migrant Workers During the COVID-19 Pandemic: A Multicenter Study From Northwest India.

OBJECTIVE: To examine the various psychosocial factors associated with reverse migration among migrant workers during the coronavirus disease 2019 (COVID-19) lockdown in India. METHODS: A cross-sectional multicenter study was conducted at 4 sites in Northwest India. The migrant workers were recruited from various shelter homes, and information was gathered from reverse migrant workers and controls using various tools including a sociodemographic profile; knowledge, attitudes, and practices questionnaire; and reasons for migration and reverse migration questionnaires. A total of 275 reverse migrant workers and 276 controls participated in the study. RESULTS: There was a considerable difference between reverse migrant workers and controls regarding the question of whether it was safe to travel during lockdown (76.0% vs 26.4%, respectively). The most common route of spread of COVID-19 infection was through touching and sneezing, and symptoms were fever, dry cough, and sore throat in both groups. Reverse migrant workers had low self-esteem and were reluctant to participate in customs of their migration city. A large number of reverse migrant workers reported that they had no money to survive, worried about family back home at their village, felt pressured by family members to come back to the village, and had been terminated from their job. CONCLUSIONS: Reverse migrant workers had the attitude that it was safe to travel during the lockdown. About one-fifth of the reverse migrant workers reported no place to live and fear of getting an infection. The reverse migrant workers also reported feeling low and gloomy, restless, and uncertain about the future and fear of death. Lack of jobs was a major factor driving migrant workers from their native homes.

Migrant Workers' Needs and Perceptions While Lodged in a Shelter Home in India During the COVID-19 Pandemic.

OBJECTIVE: India is combating a large-scale migrant crisis in many states during the coronavirus disease 2019 (COVID-19) pandemic. The objective of this study was to identify migrant workers needs and perceptions regarding lockdown while staying in a shelter home during the COVID-19 crisis. METHODS: This exploratory study was conducted with 54 migrants staying in a makeshift shelter home in Chandigarh, India. Three discussions were conducted with groups consisting of 15-20 participants to maintain social distancing. Five discussion questions were designed to facilitate group discussions. RESULTS: One important theme among migrants was their eagerness to return to their native homes. Participants were also concerned about pending agriculture-related work, their families back home, and job insecurity. Most of the migrants supported the government-mandated lockdown and agreed that they would follow all instructions. CONCLUSIONS: Physiologic requirements, safety, and security were the predominant needs of the migrant workers while staying in the shelter home during lockdown. The participants feared contracting COVID-19 and were uncertain about when and how they would return to their native homes.

Neuropsychiatric manifestations of methyl iodide toxicity.

Methyl iodide is an industrial chemical used in methylation for pharmaceutical intermediates. Its toxicity is a rare industrial hazard. Its toxicity is reported with both acute sudden exposure and gradual exposure. The authors report a case of methyl iodide toxicity occurring in a 47 year-old male with sudden exposure to this chemical. He presented with neuropsychiatric symptoms primarily slurring of speech, ataxia followed by delusion and hallucinations which resolved within 2 weeks with parenteral thiamine and an antipsychotic. Symptoms reappeared after a re-exposure, this time with more prominent psychiatric symptoms which were late to resolve (4 weeks) with similar treatment. Neuroimaging revealed hyperintensities in posterior regions of the brain which resolved after 4 weeks. The patient had prominent neurocognitive deficits which were persistent. The case highlights the rare chemical toxicity with neuropsychiatric manifestations with persistent neurocognitive symptoms.

Sexual Health of Postmenopausal Women in North India.

BACKGROUND: Sexual health is the most important aspect of person's well being, self-esteem and quality of life. Sexual pleasure leads to enhanced conjugal relationships and an overall healthy psychological state. There is paucity of data on sexual health of postmenopausal women. AIMS AND OBJECTIVES: To assess the prevalence and determinants of sexual health in postmenopausal women of North India. MATERIALS AND METHODS: The study was conducted over a period of 18 months, from January 2016 to June 2017. Standard FSFI-6 questionnaire and various socio-demographic factors were used to analyse the sexual health of 110 menopausal women. RESULTS: 80.9% postmenopausal women reported sexual dysfunction (SD). We found more sexual dysfunction in postmenopausal women with increasing age and increasing duration of menopause. Satisfied past sexual experience, joint family structure, low socioeconomic and education status were found to be important determinants of sexual health of postmenopausal females. Parity, substance use and past medical and gynaecological history of participants and various partner's factors like medical disorders, substance use and sexual disorders showed no association with sexual health in postmenopausal females. CONCLUSION: Sexuality varies with cultural and social differences across the globe. The prevalence of female sexual dysfunction in our study is much higher because Indian women are suppressed, self conscious, inhibited and hesistant to talk about their sexual problems with health care professionals. Also revalidation of the FSFI tool for Indian population is required. Further studies are needed to evaluate the sexual health in postmenopausal women.

Prevalence of substance use disorders in Punjab: Findings from National Mental Health Survey.

Background & objectives: Substance use disorders are a major public health concern in Punjab. However, reliable estimates of prevalence of substance use disorders are not available for the State. The present study reports estimates of prevalence of substance use disorders in Punjab, conducted as part of National Mental Health Survey, India. Methods: Using multistage stratified random cluster sampling, 2895 individuals from 719 households of 60 clusters (from 4 districts of Punjab) were interviewed. Mini International Neuropsychiatric Interview and Fagerstrom nicotine dependence scale were used to assess substance use disorders. Results: The sample comprised almost equal numbers of males and females. Nearly 80 per cent had less than or equal to high school education, and 70 per cent were married. The weighted prevalence of alcohol and other substance use disorders was 7.9 and 2.48 per cent, respectively. The prevalence of tobacco dependence was 5.5 per cent; 35 per cent households had one person with substance use disorder. The prevalence was highest in the productive age group (30-39 yr), urban metro and less educated persons. The prevalence of alcohol and other substance use disorders was much higher in Punjab as compared to other States where survey was done. Tobacco dependence was lowest in Punjab. Majority (87%) of the persons with substance use disorders did not suffer from any other mental disorder. Treatment gap was 80 per cent. Interpretation & conclusions: Punjab has a high burden of substance use disorders. The estimates will help clinicians and policymakers to plan the strategies against the menace of substance use disorders effectively.

Efficacy of buprenorphine and clonidine in opioid detoxification: A hospital- based study.

BACKGROUND: The need for effective and accepted method for opioid detoxification is ever increasing. Sublingual buprenorphine and oral clonidine have been effective in opioid detoxification. As often, there is a great variation in the dosage of buprenorphine and clonidine prescribed by the clinicians; hence, there is a felt need to find an effective dosage for a favorable outcome of opioid detoxification. OBJECTIVE: The objective of this study was to compare the effectiveness of different doses of sublingual buprenorphine and clonidine in opioid detoxification. MATERIALS AND METHODS: A total of 100 patients with the diagnosis of opioid dependence as per the international classification of diseases-10 criteria were recruited for this study. Participants were assigned randomly into four groups - low-dose clonidine, high-dose clonidine, low-dose sublingual buprenorphine, and high sublingual dose buprenorphine using a computer-generated random number table, resulting in 25, 26, 23, and 26 patients in each group, respectively. RESULTS: The four groups had comparable scores on all the items of "stages of change readiness and treatment eagerness scale" for the assessment of motivation at baseline. Progressive decrease in withdrawal score was seen in all the groups on "clinical opiate withdrawal scale" and "subjective opiate withdrawal scale." CONCLUSION: From the current study, we can infer that both low and high doses of buprenorphine and clonidine are comparable regarding controlling withdrawal.

Disability and socio-economic impact of mental disorders in the state of Punjab, India: Findings from national mental health survey, 2015-2016.

BACKGROUND: Mental illness results in a plethora of distressing issues, has tremendous socio-economic impact and causes socio-occupational dysfunction in the individual as well as the caregivers. There is a felt need to explore the disability caused by mental illness and the associated socio-economic impact at the population level in a developing nation like India. AIMS: To elucidate the disability and socio-economic impact associated with mental illness at the individual and household levels for the state of Punjab in India. METHOD: This was a multisite cross-sectional study carried out during 2015-2016 (as a part of the National Mental Health Survey of India) in three districts and one urban metro area of Punjab. The sample was selected using multi-stage, stratified, random cluster sampling technique, with random selection based on Probability Proportionate to Size (PPS) at different stages. A validated set of questions was used to assess the socio-economic impact of mental illness and the Sheehan Disability Scale was used to document self-perceived disability among individuals with mental morbidity. Median (IQR) and proportions were used to summarize quantitative and qualitative data, respectively Results: Subjects with any mental morbidity reported disability of varying severities across different domains of life; family life was affected the most (70.1%). One in every six persons reported that their mental illness interfered with their daily activities to a large extent. Economic burden was high and a typical family would spend about INR 1500/month (US$23) towards the treatment of its member with mental morbidity. Family members had to forego their work for at least 7 days in 3 months to take care of their relative with mental illness. CONCLUSION: Mental illness causes disability in the individual and has tremendous socio-economic impact on the family, incapacitating a family's productivity to a large extent and thus affecting the society.

Prevalence of mental disorders in Punjab: Findings from National Mental Health Survey.

BACKGROUND: Knowledge of the prevalence of mental disorders is essential for setting up services and allocation of resources. Existing studies suffer from methodological problems which limit their utility and generalizability. There was a long felt need to conduct a scientifically robust study in different regions of India to have national prevalence rates. AIMS: This study aims to estimate the prevalence of mental disorders in a representative population of Punjab as a part of the National Mental Health Survey. SETTINGS AND DESIGN: Community-based survey carried out in rural and urban areas of Punjab using multistage, stratified, random cluster sampling technique and random selection was based on Probability Proportion to Size. MATERIALS AND METHODS: The survey was conducted in 60 clusters of 4 districts (Faridkot, Ludhiana, Moga, and Patiala) of Punjab. Mini-International Neuropsychiatric Interview adult version 6.0 for mental morbidity, case definition for generalized tonic-clonic seizure, an expansion of the Fagerström Nicotine Dependence Scale for tobacco use and screener for intellectual disability were used. Appropriate statistical methods were applied. RESULTS: A total of 2895 respondents aged >18 years from 719 households were interviewed. The prevalence of lifetime and current mental morbidity was 17.94% and 13.42%, respectively. Higher prevalence of mental morbidity was found among persons aged >60 years and those belonging to lower income group and rural population. CONCLUSIONS: The prevalence of mental morbidity is high in the population. The findings give a clear picture of magnitude of the problem and will help policy planners to tackle the situation which looks grave and warrants immediate intervention.

Sociodemographic and Clinical Predictors of Response in Manic Episodes: A Naturalistic, Prospective, Cohort Study.

BACKGROUND: Response to treatment of a manic episode is dependent on several sociodemographic and clinical factors as reported by researchers from other countries. The prescription of mood stabilizers and/or antipsychotics for manic episode depends on these factors. There is a lack of availability of data from India on this topic. Hence, this study was planned to identify the predictors of pharmacological response. MATERIALS AND METHODS: Forty-two patients with a diagnosis of bipolar affective disorder current episode manic were enrolled and assessed for sociodemographic variables and clinical variables such as age of onset, family history, comorbidities, index episode, and number of past episodes. They were divided into four groups depending on the treatment they were receiving, namely, lithium with an antipsychotic (n = 25), lithium with divalproex and an antipsychotic (n = 8), divalproex with an antipsychotic (n = 5), and the miscellaneous group (n = 4). The primary outcome measure was improvement in the Young Mania Rating Scale score and secondary outcome measure was duration of ward stay. RESULTS: There was a significant improvement in all the treatment modalities and it was comparable. There was no significant impact of any sociodemographic or clinical variable on treatment outcome except that females had significantly better response than males. There was nearly significant shorter duration of hospitalization in the lithium and antipsychotics groups compared to divalproex group. CONCLUSION: All treatment modalities are equally efficacious in the management of manic episode in short term. However, lithium and antipsychotics tend to produce early response than divalproex. Other sociodemographic and clinical predictors were not significantly associated with response.

Efficacy and Tolerability of Clozapine versus Quetiapine in Treatment-resistant Schizophrenia.

OBJECTIVES: To compare the efficacy and tolerability of clozapine and quetiapine in patients with treatment-resistant schizophrenia (TRS). PATIENTS AND METHODS: In this prospective, randomized, open label study of 14 weeks, 53 patients with schizophrenia diagnosed as per ICD-10 and fulfilling the modified version of Conley and Kelly's criteria of TRS were randomly assigned to receive clozapine or quetiapine as per a computer-generated random table. After 2-weeks of dose-titration phase, doses were fixed at minimum therapeutic dose and subsequently adjusted according to the clinical improvement. All patients received dosage of respective drug in therapeutic range. 13 patients were lost to follow up. Treatment efficacy and side effects were evaluated with standardized rating scales. RESULTS: Clozapine group (reduction in total score: mean=14.45, SD=10.39) had significantly greater reductions (P=0.004; CI=3.541-17.059) in the Positive and Negative Syndrome Scale (PANSS) total score, PANSS positive subscale and PANSS general psychopathology subscale at 14 weeks in comparison to the quetiapine group (reduction in total score: mean=4.15, SD=10.71). Significant reduction in PANSS negative subscale was seen with both drugs but no significant difference was present between the two drugs. At 14 weeks, 30% patients in clozapine group and 15% patients in quetiapine group showed response. Clozapine led to significantly greater side effects (P< 0.001, CI=2.241-6.059) on Glassgow Antipsychotic Side-effect Scale (GASS) than quetiapine. CONCLUSIONS: Clozapine was found to be more efficacious than quetiapine in patients with TRS but was associated with greater side effects. Both the drugs were found to be equally effective in reducing the negative symptoms.

Comparative study of clozapine versus risperidone in treatment-naive, first-episode schizophrenia: A pilot study.

BACKGROUND & OBJECTIVES: Clozapine may be more useful in treatment-naive patients with first-episode schizophrenia for better symptoms control and improving quality of life. The current study was carried out to compare the efficacy and tolerability of clozapine versus risperidone in treatment-naive, first-episode patients of schizophrenia. METHODS: This was a comparative, open-label, six months prospective study of treatment-naive, first-episode patients with schizophrenia between the age group of 18 and 40 yr diagnosed as per the International Classification of Diseases-10 (ICD-10) criteria. A total of 63 patients were recruited and randomly assigned to clozapine group or risperidone group using computer-generated random number tables. Eight patients were lost to follow up. The dosages of the respective drugs were kept in therapeutic range of 200-600 mg/day and 4-8 mg/day orally for clozapine and risperidone, respectively. RESULTS: On general psychopathology score, after six months of intervention, clozapine led to 60.32 per cent mean reduction in Positive and Negative Syndrome Scale (PANSS) for Schizophrenia total score while risperidone led to 56.35 per cent mean reduction in PANSS total score, which meant more improvement with clozapine. Clozapine group was found to have significant improvement in quality of life (P = 0.04339). On Glasgow Antipsychotic Side-effect Scale, clozapine was superior to risperidone. The most common side effects observed in clozapine group were oversedation (78.96%) and dizziness (55.23%), and in risperidone group, common side effects were rigidity (62.36%), sedation (38.69%), tremors (65.69%) and menstrual irregularities in 80.25 per cent of female patients. INTERPRETATION & CONCLUSIONS: The findings of this preliminary study showed clozapine as a better choice than risperidone in terms of efficacy, tolerability and better quality of life in treatment-naive, first-episode schizophrenia. However, further studies need to be done on a larger group of patients to confirm the findings.

Comparative efficacy of methylphenidate and atomoxetine in oppositional defiant disorder comorbid with attention deficit hyperactivity disorder.

BACKGROUND: Oppositional defiant disorder (ODD) is frequently comorbid with attention deficit hyperactivity disorder (ADHD) and is associated with substantial functional impairments. Methylphenidate and atomoxetine are well-established drugs for the management of ADHD. Some studies from Western countries have reported these drugs to be effective in the management of ODD comorbid with ADHD. This study aimed to assess if methylphenidate and atomoxetine are efficacious in treating Indian children with ODD comorbid with ADHD. SUBJECTS AND METHODS: In this prospective, open-label study, 37 patients of age 6-14 years with a diagnosis of ODD comorbid with ADHD randomly received either methylphenidate (dose 0.2-1 mg/kg/day) or atomoxetine (dose 0.5-1.2 mg/kg/day) for 8 weeks. Improvements in ADHD and ODD symptoms were assessed using Vanderbilt ADHD diagnostic parent rating scale (VADPRS). RESULTS: At 8 weeks, there were statistically significant improvements in both ADHD and ODD symptoms in both methylphenidate and atomoxetine groups, as per VADPRS. The improvements produced and tolerability was comparable in the two groups. 80% of the patients from methylphenidate group and 64.3% patients from atomoxetine group ceased to fulfill the criteria for the presence of ODD at 8 weeks. CONCLUSIONS: Methylphenidate and atomoxetine are effective in the treatment of ODD comorbid with ADHD in short duration.

Impact of psychiatry training on attitude of medical students toward mental illness and psychiatry.

CONTEXT: Attitude of fresh graduates toward psychiatric patients is important to bridge the treatment gap due to mental illness. Psychiatry as a subject has been neglected in the undergraduates of MBBS. AIMS: (1) To compare the attitude of medical students and interns in a medical college toward mental illness and psychiatry. (2) To assess the impact of psychiatric training on attitude toward the mentally ill person and mental illness. SETTINGS AND DESIGN: Cross-sectional, single assessment study conducted at a tertiary hospital. SUBJECTS AND METHODS: Participants consisted of medical students of 1(st) and 2(nd) year who didn't have any exposure to psychiatry and interns, who had completed their compulsory 2 week clinical posting in psychiatry. Participants were individually administered sociodemographic proforma, General Health Questionnaire-12 (GHQ-12), opinion about mental illness (OMI) scale, and attitude to psychiatry-29 (ATP-29) scale. STATISTICAL ANALYSIS: Standard descriptive statistics (mean, percentage), Chi-square test. RESULTS: A total of 135 participants formed the study sample, with 48, 47, and 40 participants from 1(st) year, 2(nd) year and interns, respectively. Mean GHQ score was 14.03 for the entire sample. There was better outlook of interns toward psychiatry and patients with mental disorders in comparison to fresh graduate students in some areas. Overall, negative attitude toward mental illness and psychiatry was reflected. CONCLUSIONS: Exposure to psychiatry as per the current curriculum seems to have a limited influence in bringing a positive change in OMI and psychiatry.

Comparative short term efficacy and tolerability of methylphenidate and atomoxetine in attention deficit hyperactivity disorder.

OBJECTIVE: To compare the short term efficacy and tolerability of methylphenidate and atomoxetine in children with Attention deficit hyperactivity disorder (ADHD). DESIGN: Open label randomized parallel group clinical trial. SETTING: Child Guidance Clinic of a tertiary care hospital of Northern India from October 2010 to June 2012. PARTICIPANTS: 69 patients (age 6-14 y) with a diagnosis of ADHD receiving methylphenidate or atomoxetine. INTERVENTION: Methylphenidate (0.2-1 mg/kg/d) or atomoxetine (0.5-1.2 mg/kg/d) for eight weeks. MAIN OUTCOME MEASURES: Treatment response (>25% change in baseline Vanderbilt ADHD Diagnostic Parent Rating Scale (VADPRS); Vanderbilt ADHD Diagnostic Teacher Rating Scale (VADTRS); Clinical Global Impression Severity Scale (CGI-S) at eight weeks and adverse effects. RESULTS: Treatment response was observed in 90.7% patients from methylphenidate group and 86.2% patients of atomoxetine group at an average dose of 0.45 mg/kg/d and 0.61 mg/kg/d, respectively. The patients showed comparable improvement on VADPRS (P=0.500), VADTRS (P=0.264) and CGI-S (P=0.997). Weight loss was significantly higher in methylphenidate group (-0.57±0.78 kg; P=0.001), and heart rate increase was observed at higher rate in atomoxetine group (7± 9 bpm; P=0.021). CONCLUSIONS: Methylphenidate and atomoxetine are efficacious in Indian children with ADHD at lesser doses than previously used. Their efficacy and tolerability are comparable.
