RESUMEN

Background: Among the Indian adolescents, the prevalence of psychiatric morbidity and alcohol use disorders (AUD) are 7.3% and 1.3%. However, no separate data are available for indigenous tribal populations. This study estimated the prevalence of psychiatric morbidity and AUD and associated socio-demographic factors among adolescents in the tribal communities in three widely varying states in India. Methods: Using validated Indian versions of the MINI 6.0, MINI Kid 6.0, and ICD-10 criteria, we conducted a cross-sectional survey from January to May 2019 in three Indian sites: Valsad, Gujarat (western India); Nilgiris, Tamil Nadu (south India); and East Khasi Hills district of Meghalaya (north-east India) on 623 indigenous tribal adolescents. Results: Aggregate prevalence of any psychiatric morbidity was 15.9% (95% CI: 13.1-19.0) (males: 13.6%, 95% CI: 10.0-18.1; females: 17.9%, 95% CI: 13.9-22.6), with site-wise statistically significant differences: Gujarat: 23.8% (95% CI: 18.1-30.2), Meghalaya: 17.1% (95% CI: 12.4-22.7), Tamil Nadu: 6.2% (95% CI: 3.2-10.5). The prevalence of diagnostic groups was mood disorders 6.4% (n = 40), neurotic- and stress-related disorders 9.1% (n = 57), phobic anxiety disorder 6.3% (n = 39), AUD 2.7% (n = 17), behavioral and emotional disorders 2.7% (n = 17), and obsessive-compulsive disorder 2.2% (n = 14). These differed across the sites. Conclusion: The prevalence of psychiatric morbidity in adolescent tribals is approximately twice the national average. The most common psychiatric morbidities reported are mood (affective) disorders, neurotic- and stress-related disorders, phobic anxiety disorder, AUD, behavioral and emotional disorders, andobsessive-compulsive disorder.

RESUMEN

We developed and tested the Indian Autism Screening Questionnaire (IASQ), which was reported to be reliable and valid as compared to the Indian Scale for Assessment of Autism (ISAA) and the Childhood Autism Rating Scale -2 (CARS2). The present study describes the feasibility, acceptability, sociodemographic and developmental details of IASQ study participants in 5 settings- a psychiatry outpatients' clinic (n = 145), a specialised paediatric clinic (n = 24), a speciality disability centre (n = 174), a primary school (n = 41) and a government housing colony (n = 255). The IASQ could be easily administered and understood. Consistent with prior reports, the male-female ratio of participants with autism was 3.8:1. Developmental complications were reported more frequently in clinical settings, while delivery by Caesarean section was commoner among community-dwelling higher socioeconomic status mothers (53% of the officers' sample). Mothers of participants with autism more frequently reported Caesarean section birth for the proband (χ2 = 41.61, p < .0001) and prenatal and postnatal complications. Binary logistic regression confirmed that perinatal complications in the mother and father's (older) age at birth of the participant were associated with autism. The IASQ is a reliable, practical tool for screening for autism in clinical and non-clinical settings in India.

RESUMEN

With a steady rise in mental health issues such as depression, anxiety, and post-traumatic stress disorder (PTSD) in Kashmir, the need to address mental health in this region becomes important. This paper reports on traditional and current community mental health coping mechanisms among residents in Kashmir. Six focus group discussions (FGD) were facilitated with key informants. Data were analyzed via a thematic analytic approach. Community coping mechanisms reported include social spaces and shared chore spaces, cultural practices, shrines and religious places, faithealers. These findings demonstrate community strengths that can leverage to build additional coping strategies and resilience among people.

RESUMEN

This scoping review aimed to synthesise current evidence related to psycho-social groups as part of community-based mental health interventions in South Asia. We used a realist lens to pay attention to the contexts and mechanisms supporting positive outcomes. We included studies published from January 2007 to February 2022 that: were based in communities in South Asia, included a group component, reported on interventions with a clear psychosocial component, targeted adults and were implemented by lay community health workers. Two reviewers extracted data on intervention components, groups and facilitators, participant demographics and enabling contexts, mechanisms and outcomes. Expert reference panels including people with lived experience of psycho-social disability, mental health professionals and policy makers confirmed the validity and relevance of initial review findings. The review examined 15 interventions represented by 42 papers. Only four interventions were solely psycho-social and nearly all included psychoeducation and economic support. Only 8 of the 46 quantitative outcome measures used were developed in South Asia. In a context of social exclusion and limited autonomy for people with psychosocial disability, psychosocial support groups triggered five key mechanisms. Trusted relationships undergirded all mechanisms, and provided a sense of inclusion, social support and of being able to manage mental distress due to improved skills and knowledge. Over time group members felt a sense of belonging and collective strength meaning they were better able to advocate for their own well-being and address upstream social health determinants. This led to outcomes of improved mental health and social participation across the realms of intrapersonal, interpersonal and community. Psychosocial groups merit greater attention as an active ingredient in community interventions and also as an effective, relevant, acceptable and scalable platform that can promote and increase mental health in communities, through facilitation by lay community health workers.

RESUMEN

Evidence shows that stigma negatively influences the quality of life of persons with severe mental illness. Nonetheless, stigma towards mental illness is lower among persons with a lived experience of mental illness compared to the rest of the population. Understanding the association between stigma of mental illness and the mental status of individuals living in urban India and whether this association is moderated by demographic factors opens a new avenue for prevention of social exclusion. Persons diagnosed with schizophrenia, bipolar disorder, or severe unipolar depression (cases, n = 647) were recruited from among hospital patients in New Delhi between November 2011 and June 2012 and matched with non-psychiatric urban dwellers by age, sex, and location of residence (controls, n = 649). Propensity score matching with multivariable linear regression was used to test whether stigma towards mental illness, measured by a 13-item Stigma Questionnaire, differed between cases and controls. Cases reported significantly lower stigma scores than controls (b = -0.50, p < 0.0001). The strength of the association between mental illness and stigma was not affected after controlling for age, caste, sex, education, and employment status, while wealth marginally reduced the strength of the association. These findings suggest individuals with a lived experience of mental illness, in New Delhi, India, may be more tolerant towards mental illness and support the need to involve persons with lived experience in the development and implementation of health promotional campaigns and programs aimed at reducing stigma towards mental illness.

RESUMEN

Genetic perturbations in dopamine neurotransmission and calcium signaling pathways are implicated in the etiology of schizophrenia. We aimed to test the association of a functional splice variant each in Dopamine ß-Hydroxylase (DBH; rs1108580) and Calcium voltage-gated channel subunit alpha1 C (CACNA1C; rs1006737) genes in these pathways with schizophrenia (506 cases, 443 controls); Abnormal Involuntary Movement Scale (AIMS) scores in subjects assessed for tardive dyskinesia (76 TD-positive, 95 TD-negative) and Penn Computerized Neurocognitive Battery (PennCNB) scores (334 cases, 234 controls). The effect of smoking status and SNP genotypes on AIMS scores were assessed using ANOVA; health status and SNP genotypes on three performance functions of PennCNB cognitive domains were assessed by ANCOVA with age and sex as covariates. Association with Positive and Negative Syndrome Scale (PANSS) scores in the TD cohort and cognitive scores in healthy controls of the cognition cohort were tested by linear regression. None of the markers were associated with schizophrenia. Smoking status [F(2, 139) = 10.6; p = 5 × 10-5], rs1006737 [F(2, 139) = 7.1; p = 0.001], TD status*smoking [F(2, 139) = 8.0; p = 5.0 × 10-4] and smoking status*rs1006737 [F(4, 139) = 2.7; p = 0.03] had an effect on AIMS score. Furthermore, rs1006737 was associated with orofacial [F(2, 139) = 4.6; p = 0.01] and limb-truncal TD [(F(2, 139) = 3.8; p = 0.02]. Main effect of rs1108580 on working memoryprocessing speed [F(2, 544) = 3.8; p = 0.03] and rs1006737 on spatial abilityefficiency [F(1, 550) = 9.4; p = 0.02] was identified. Health status*rs1006737 interaction had an effect on spatial memoryprocessing speed [F(1, 550) = 6.9; p = 0.01]. Allelic/genotypic association (p = 0.01/0.03) of rs1006737 with disorganized/concrete factor and allelic association of rs1108580 (p = 0.04) with a depressive factor of PANSS was observed in the TD-negative subcohort. Allelic association of rs1006737 with sensorimotor dexterityaccuracy (p = 0.03), attentionefficiency (p = 0.05), and spatial abilityefficiency (p = 0.02); allelic association of rs1108580 with face memoryaccuracy (p = 0.05) and emotionefficiency (p = 0.05); and allelic/genotypic association with emotionaccuracy (p = 0.003/0.009) were observed in healthy controls of the cognition cohort. These association findings may have direct implications for personalized medicine and cognitive remediation.

RESUMEN

Background: Weight gain associated with atypical antipsychotic medications need to be well managed. We set out: 1. To test the effect of acetazolamide on weight gain associated with antipsychotics 2. To assess improvement in psychotic symptoms using the Brief Psychiatric Rating Scale score on patients receiving acetazolamide. Methods and Materials: This open-label study conducted after institutional ethical clearance from December 2018 to August 2020 included 34 drug-naive patients or patients on antipsychotic risperidone or olanzapine for less than one month. They were divided into two groups of 17 each as a case group (treatment as usual + acetazolamide) and a control group (treatment as usual) who were followed up for eight weeks. The patient's physical characteristics were recorded at baseline and during follow-ups. The Brief psychiatric rating scale (BPRS) and clinical global impression (CGI) scores were compared for the cases and controls. Results: The study showed non-significant reduction in the weight (-0.57 ± 1.06 kg), body mass index (BMI) (-0.23 ± 0.76 kg/m2) and abdominal circumference (-0.47 ± 1.37 cm) in the patients receiving oral acetazolamide at the end of two months as compared to controls where there was significant increase in the weight (+2.62 ± 1.09 kg), BMI (+1.03 ± 0.44 kg/m2) and abdominal circumference (+2.21 ± 1.33 cm, P = 0.001). Similarly, the BPRS and CGI scores were significantly reduced in both arms, with satisfaction rates better among the cases compared to controls. Conclusion: There was a non-significant reduction in the weight, body mass index, abdominal circumference, and brief psychiatric rating scale scores in patients treated with acetazolamide.Ethics committee protocol number: - 2018/244CTRI India registration number: CTRI/2019/05/018884.

RESUMEN

Despite the high burden of mental disorders in low- and middle-income countries (LMICs), less than 25% of those in need have access to appropriate services, in part due to a scarcity of locally relevant, evidence-based interventions and models of care. To address this gap, researchers from India and the United States and the Indian Council of Medical Research (ICMR) collaboratively developed a "Grantathon" model to provide mentored research training to 24 new principal investigators (PIs). This included a week-long didactic training, a customized web-based data entry/analysis system and a National Coordination Unit (NCU) to support PIs and track process objectives. Outcome objectives were assessed via scholarly output including publications, awards received and subsequent grants that were leveraged. Multiple mentorship strategies including collaborative problem-solving approaches were used to foster single-centre and multicentre research. Flexible, approachable and engaged support from mentors helped PIs overcome research barriers, and the NCU addressed local policy and day-to-day challenges through informal monthly review meetings. Bi-annual formal review presentations by all PIs continued through the COVID-19 pandemic, enabling interim results reporting and scientific review, also serving to reinforce accountability. To date, more than 33 publications, 47 scientific presentations, 12 awards, two measurement tools, five intervention manuals and eight research grants have been generated in an open-access environment. The Grantathon is a successful model for building research capacity and improving mental health research in India that could be adopted for use in other LMICs.

RESUMEN

Genetic etiology of schizophrenia is poorly understood despite large genome-wide association data. Long non-coding RNAs (lncRNAs) with a probable regulatory role are emerging as important players in neuro-psychiatric disorders including schizophrenia. Prioritising important lncRNAs and analyses of their holistic interaction with their target genes may provide insights into disease biology/etiology. Of the 3843 lncRNA SNPs reported in schizophrenia GWASs extracted using lincSNP 2.0, we prioritised n = 247 based on association strength, minor allele frequency and regulatory potential and mapped them to lncRNAs. lncRNAs were then prioritised based on their expression in brain using lncRBase, epigenetic role using 3D SNP and functional relevance to schizophrenia etiology. 18 SNPs were finally tested for association with schizophrenia (n = 930) and its endophenotypes-tardive dyskinesia (n = 176) and cognition (n = 565) using a case-control approach. Associated SNPs were characterised by ChIP seq, eQTL, and transcription factor binding site (TFBS) data using FeatSNP. Of the eight SNPs significantly associated, rs2072806 in lncRNA hsaLB_IO39983 with regulatory effect on BTN3A2 was associated with schizophrenia (p = 0.006); rs2710323 in hsaLB_IO_2331 with role in dysregulation of ITIH1 with tardive dyskinesia (p < 0.05); and four SNPs with significant cognition score reduction (p < 0.05) in cases. Two of these with two additional variants in eQTL were observed among controls (p < 0.05), acting likely as enhancer SNPs and/or altering TFBS of eQTL mapped downstream genes. This study highlights important lncRNAs in schizophrenia and provides a proof of concept of novel interactions of lncRNAs with protein-coding genes to elicit alterations in immune/inflammatory pathways of schizophrenia.

RESUMEN

In recent years mental health has emerged as a major health threat in low income countries like India. In response, mental health care has been integrated into primary health care, in turn creating a rising demand for trained and skillful mental health professionals. This study was conducted in district Budgam (J&K), India with the aim of providing training to community health workers (CHWs) and measuring the change using pre- and post-training evaluations. The pre and post tests were undertaken, assessing changes in mental health literacy at three different points of time: pre-training, post-training, and three month follow-up. Mental health literacy was assessed using the interviewer-administered Mental Health Literacy Survey. The training intervention was a five-day course based on a facilitator's manual developed specifically for community health workers in India. A total of 25 community health workers from rural areas of Budgam District (mostly Integrated Child Development Service supervisors), Health Educators and Anganwadi Workers, were engaged for the study. Findings demonstrate that the training course improved participants' ability to recognize any mental health disorders. There was a clear distinction between the level of awareness pre- and post- training. The results were statistically significant on various domains Ability to recognize disorders (Pre-post P= 0.001), Knowledge of the professional help available (Pre-post p= 0.000), Attitudes that promote the recognition or appropriate help-seeking behavior (Pre-post p= 0.000) (p<0.05). Further follow up after three months was done. The mixed findings from this study, suggesting the training course has potential to improve some aspects of mental health literacy among the CHWs, including their understanding of various mental health problems.

RESUMEN

BACKGROUND: The study investigated the psychometric properties of the Community, Assessment of Psychic Experiences (CAPE-42), a self-report instrument in Indians. METHOD: CAPE-42 was translated in Hindi and tested on 312 Indian adults recruited online and through paper-pencil assessment. Confirmatory factor analysis (CFA) was employed to establish the factor structure of the positive, negative and depressive dimensions of CAPE-42: the bifactor model was tested to evaluate whether items converge into a major single factor defining psychotic-proneness in individuals. Latent class analysis (LCA) was conducted to identify subgroups with a different endorsement of subclinical psychotic symptoms. , RESULTS: CAPE-Hindi showed good reliability (Cronbach's alpha>0.80). CFA confirmed, a good fit for the bifactor model, factor loading was acceptable for all items in the general factor (Omega-h =0.83) and explained the primary variance of the subscales. Residual variance was explained by the positive, negative and depressive factors (Omega H =0.33, 0.04 and 0.12, respectively). LCA identified three classes traceable, to the three dimensions; a low endorsement group (n = 155; 50 %); a less consistent, group with endorsement on positive and depressive items (n = 117; 38 %), and a high, endorsement group (n = 40;13 %). CONCLUSION: Hindi CAPE-42 showed good reliability and factorial validity.

RESUMEN

My early exposure to mental illness in our community, the plight of mentally ill people and their families drove me to seek postgraduate training in psychiatry in India. I realized early on that only research could make an impact on the scale that was needed. My contacts with thoughtful scientists and mentors helped me understand that by training enthusiastic individuals - especially women, multi-focussed research could make a substantial impact and have a multiplier effect. I thus devoted my life not only to research, but research-based training. I outline below our training programs and their outcomes.

RESUMEN

Background: The functional outcome of the debilitating mental illness schizophrenia (SZ) has an integral role in cognition. The thyroid hormone has a vital role in the developmental stages and functioning of the human brain. Aim: This study aimed to evaluate the relationship between thyroid functions, cognition, and functional imaging of the brain in persons with SZ. Materials and Methods: Sixty SZ (Diagnostic and Statistical Manual (DSM-5)) persons, aged 18-50 years of both genders, were recruited in this cross-sectional observational study. Positive and Negative Syndrome Scale (PANSS) and Trail Making Tests (TMTs) A and B were administered to all patients. To assess the level of thyroid hormone, a test was conducted. Functional connectivity of the brain was assessed using resting-state functional magnetic resonance imaging (rs-fMRI). Data analysis was performed by descriptive and analytical statistical methods. FSL version 5.9 (FMRIB's) software was used for analyses of fMRI neuroimages. Results: There were no significant differences between the two populations on sociodemographic factors. The average value for thyroid-stimulating hormone (TSH) in the hypothyroid group (n = 12) and the euthyroid group (n = 47) was 8.38 mIU/l and 2.44 mIU/l, respectively. The average time in seconds for TMT-A and TMT-B was 87.27 and 218.27 in the hypothyroid group and 97.07 and 293.27 in the euthyroid group, respectively. Similarly, in the sample matched on age, gender, and age at onset of illness, there were no significant differences in demographic and clinical factors and resting-state network (RSN) between the hypothyroid (N = 10) and euthyroid (N = 10) groups. Conclusion: No differences were found in the functional brain network between the hypothyroid and euthyroid groups as the study sample did not include clinically hypothyroid persons with SZ.

RESUMEN

The Indian Autism Screening Questionnaire (IASQ), derived from the Indian Scale for Assessment of Autism ISAA (the mandated tool for autism in India), is an autism screening instrument for use in the general population by minimally trained workers. While ISAA has 40 items with four anchor points, the IASQ is a 10-item questionnaire with yes/no answers. It was initially validated using the ISAA. During its development the ISAA was itself compared to the Childhood Autism Rating Scale version 1 (ISAA Manual). In the present study, we evaluated both the ISAA and the IASQ in relation to the Childhood Autism Rating Scale version 2 (CARS-2). METHODS: Participants were recruited from three settings: a referral clinic for neurodevelopmental conditions run by the Department of Paediatrics of a tertiary care teaching hospital (NDC OPD), the outpatient department of an institute for disability and rehabilitation (NIEPID), and from the community (CGOC). Persons between ages 3-18 were recruited following consent or assent (parent and child/adolescent). The IASQ was administered by a minimally trained administrator. It was followed by ISAA and the CARS-2 (in alternating order, by different evaluators blind to each other) (CARS2 SV (Standard Version) and CARS2 HF (High Functioning) as applicable). Sensitivity, specificity and area under the Receiver Operator Characteristics (ROC) curve were calculated for IASQ and CARS2, as well as for ISAA and CARS2. Concordance between CARS2 and ISAA was calculated using kappa coefficient. RESULTS: A total of 285 participants (NIEPD n = 124; NDC OPD, n = 4; CGOC n = 157) (a total of 70 with autism and 215 controls) participated. IASQ and CARS2 were administered on 285 participants, while IASQ and ISAA were administered on 264 participants. When IASQ was compared to CARS2, sensitivity was 97%, specificity 81%, PPV 63%, NPV 99% at cut off 1 while these values were 97%, 92%, 79% and 99% respectively at cut off 2. There was high concordance between CARS2 and ISAA (Kappa 0.907, p<0.0001). CONCLUSIONS: IASQ has satisfactory sensitivity, specificity and concordance when compared with CARS2; it can be used for screening children with autism in community. The ISAA also showed a high concordance with CARS2, as it had with the older version of CARS.

RESUMEN

This study aimed to explore ethical dilemmas and challenges faced by young mental healthcare researchers and professionals working with survivors of suicide (hereinafter suicide survivors). Two focus group discussions (FGDs) Researcher FGD (with those engaged in suicide research) and Clinician FGD (with those providing treatment to suicide survivors) - consisting of open-ended questions and lasting for 70-90 minutes were conducted and analysed using Thematic Analysis. Five themes were identified: i) struggling with the incongruity of harm within benefit, ii) difficulty in delineating boundaries, iii) self-doubt in one's professional competence, iv) nature of suicide straining the limits of confidentiality, and v) working with structural limitations. The study helps to understand the obstacles and dilemmas encountered in adhering to ethical principles while working with vulnerable individuals.

RESUMEN

Cognition is believed to be a product of human evolution, while schizophrenia is ascribed as the by-product with cognitive impairment as it's genetically mediated endophenotype. Genomic loci associated with these traits are enriched with recent evolutionary markers such as Human accelerated regions (HARs). HARs are markedly different in humans since their divergence with chimpanzees and mostly regulate gene expression by binding to transcription factors and/or modulating chromatin interactions. We hypothesize that variants within HARs may alter such functions and thus contribute to disease pathogenesis. 49 systematically prioritized variants from 2737 genome-wide HARs were genotyped in a north-Indian schizophrenia cohort (331 cases, 235 controls). Six variants were significantly associated with cognitive impairment in schizophrenia, thirteen with general cognition in healthy individuals. These variants were mapped to 122 genes; predicted to alter 79 transcription factors binding sites and overlapped with promoters, enhancers and/or repressors. These genes and TFs are implicated in neurocognitive phenotypes, autism, schizophrenia and bipolar disorders; a few are targets of common or repurposable antipsychotics suggesting their draggability; and enriched for immune response and brain developmental pathways. Immune response has been more strongly targeted by natural selection during human evolution and has a prominent role in neurodevelopment. Thus, its disruption may have deleterious consequences for neuronal and cognitive functions. Importantly, among the 15 associated SNPs, 12 showed association in several independent GWASs of different neurocognitive functions. Further analysis of HARs may be valuable to understand their role in cognition biology and identify improved therapeutics for schizophrenia.

RESUMEN

Background: Suicide results from complex interactions of various risk factors-reasons for dying (RFD)-and protective factors-reasons for living (RFL). Suicide is not necessarily a wish to die but may be an appeal for help. We analyzed RFD and RFL in persons who had attempted suicide, through their clinical records at a Crisis Intervention Clinic (CIC). Methods: We retrospectively analyzed demographic and clinical data, and classified RFD and RFL, among patients with either ideas or attempt of suicide registered at our CIC (N = 83). Using two open-ended questions from the clinical history data, we derived their RFD or RFL; (n = 53) completed these questions regarding RFD-RFL. Results: In the total sample, males and females were equally represented and educated, but males were significantly older. Most common diagnosis was nonpsychotic mood disorder. Commonest mode of suicide attempt was hanging. Family conflict vs. family responsibility, hope vs. hopelessness, stressful life events, and negative cognitions about the self and the world were important RFD. RFL included feeling responsible, love for family and for self, hope, career success, and religious beliefs. Conclusion: RFD and RFL could both be grouped in similar categories related to family, career, hope, etc.

RESUMEN

OBJECTIVE: To design a meditation protocol and test its feasibility, acceptability and efficacy in conjunction with yoga training (YT) for persons with schizophrenia (SZ). METHODS: The meditation protocol consisted of Anapana (observing normal respiration) and Yoga Nidra (supine, restful awareness). In a single-blind randomised controlled trial, medicated and clinically stable outpatients diagnosed with SZ were randomised to receive treatment as usual (TAU), TAU augmented with YT or TAU augmented with meditation and yoga training (MYT) for 3 weeks (N = 145). Acceptability, clinical, social and cognitive functions were assessed after 3-week and 3-month post-randomisation using within-group and between-group analyses with repeated measures multivariate tests. RESULTS: No group-wise differences in compliance, study discontinuation, major/serious side effects or adverse events were noted. For six assessed clinical variables, the direction of changes were in the desired direction and the effect sizes were greater in the MYT group compared with the TAU group at both time points. Changes in social function variables were greater at 3 months than at 3 weeks. Nominally significant improvement in individual cognitive domains were noted in all groups at both time points. All effect sizes were in the small to medium range. CONCLUSION: MYT is feasible and acceptable and shows modest benefits for persons with SZ. MYT can also improve quality of life and clinical symptoms. Larger studies of longer duration are warranted.
