RESUMEN

Given the relationship between poor engagement and worse treatment outcomes, improving engagement has been the focus of attention in recent years. Engagement is a particular challenge among minoritized and otherwise challenged youth, such as those from socioeconomically disadvantaged groups, including youth in low- and middle-income countries (LMICs), where they face lower levels of access to resources, including mental health treatment. The present study describes engagement challenges that arose in an uncontrolled pre-post evaluation of a school-based, modular, multi-problem, stepped-care intervention delivered in urban Indian communities. Specifically, the study aimed to (1) characterize barriers and facilitators of youth treatment engagement; and (2) evaluate treatment acceptability and fit of treatment from the youth perspective. Youth participants completed semi-structured interviews, which were transcribed and coded using thematic analysis. Participants described numerous facilitators to engagement (e.g., positive therapeutic relationship) and reported high overall satisfaction with the intervention, while also identifying barriers to engagement (e.g., concerns about confidentiality) and offering suggestions to increase fit and acceptability (e.g., more visually appealing treatment materials). Findings highlight ways in which engagement can be enhanced and implementation supports improved to maximize treatment effectiveness among minoritized and disadvantaged youth in LMICs.

RESUMEN

BACKGROUND: Mental health problems are a leading cause of disability in adolescents worldwide. Problem solving is a well-tested mental health intervention in many populations. We aimed to investigate the effectiveness of a brief, transdiagnostic problem-solving intervention for common adolescent mental health problems when delivered by non-specialist school counsellors in New Delhi, India. METHODS: This randomised trial was done in six government-run schools (three all-boys schools, two all-girls schools, and one co-educational school) that serve low-income communities. We recruited participants from grades 9 to 12 (ages 12-20 years) by selecting students with persistently elevated mental health symptoms accompanied by distress or functional impairment. Clinical eligibility criteria were assessed by research assistants using the Hindi-language version of the Strengths and Difficulties Questionnaire (SDQ), with reference to locally validated borderline cutoff scores of 19 or greater for boys and 20 or greater for girls on the SDQ Total Difficulties scale, an abnormal score of 2 or more on the SDQ Impact scale, and persistence of more than 1 month on the SDQ Chronicity index. Participants were randomly allocated (1:1) to problem solving delivered through a brief (2-3 week) counsellor-led intervention with supporting printed materials (intervention group), or problem solving delivered via printed booklets alone (control group). Primary outcomes were adolescent-reported mental health symptoms (SDQ Total Difficulties scale) and idiographic psychosocial problems (Youth Top Problems [YTP]) at 6 weeks. Primary analyses were done on an intention-to-treat basis at the 6-week endpoint. The trial is registered with ClinicalTrials.gov, NCT03630471. FINDINGS: Participants were enrolled between Aug 20, and Dec 4, 2018. 283 eligible adolescents were referred to the trial, and 251 (89%) of these were enrolled (mean age 15·61 years; 174 [69%] boys). 125 participants were allocated to each group (after accounting for one participant in the intervention group who withdrew consent after randomisation). Primary outcome data were available for 245 (98%) participants. At 6 weeks, the mean YTP scores were 3·52 (SD 2·66) in the intervention group and 4·60 (2·75) in the control group (adjusted mean difference -1·01, 95% CI -1·63 to -0·38; adjusted effect size 0·36, 95% CI 0·11 to 0·61; p=0·0015). The mean SDQ Total Difficulties scores were 17·48 (5·45) in the intervention group and 18·33 (5·45) in the control group (-0·86, -2·14 to 0·41; 0·16, -0·09 to 0·41; p=0·18). We observed no adverse events. INTERPRETATION: A brief lay counsellor-delivered problem-solving intervention combined with printed booklets seemed to have a modest effect on psychosocial outcomes among adolescents with diverse mental health problems compared with problem-solving booklets alone. This counsellor-delivered intervention might be a suitable first-line intervention in a stepped care approach, which is being evaluated in ongoing studies. FUNDING: Wellcome Trust.

RESUMEN

BACKGROUND: The PRIDE programme aims to establish a suite of transdiagnostic psychological interventions organised around a stepped care system in Indian secondary schools. This paper describes the development of a low-intensity, first-line component of the PRIDE model. METHOD: Contextual and global evidence informed an intervention 'blueprint' with problem solving as the primary practice element. Successive iterations were tested and modified across two pilot cohort studies (N = 45; N = 39). Participants were aged 13-20 years and presenting with elevated mental health symptoms in New Delhi schools. RESULTS: The first iteration of the intervention, based on a guided self-help modality, showed promising outcomes and user satisfaction when delivered by psychologists. However, delivery was not feasible within the intended 6-week schedule, and participants struggled to use materials outside 'guidance' sessions. In Pilot 2, a modified counsellor-led problem-solving intervention was implemented by less experienced counsellors over a 3-4 week schedule. Outcomes were maintained, with indications of enhanced feasibility and acceptability. High demand was observed across both pilots, leading to more stringent eligibility criteria and a modified sensitisation plan. DISCUSSION: Findings have shaped a first-line intervention for common adolescent mental health problems in low-resource settings. A forthcoming randomised controlled trial will test its effectiveness.

RESUMEN

BACKGROUND: Conduct, anxiety, and depressive disorders account for over 75% of the adolescent mental health burden globally. The current protocol will test a low-intensity problem-solving intervention for school-going adolescents with common mental health problems in India. The protocol also tests the effects of a classroom-based sensitization intervention on the demand for counselling services in an embedded recruitment trial. METHODS/DESIGN: We will conduct a two-arm, individually randomized controlled trial in six Government-run secondary schools in New Delhi. The targeted sample is 240 adolescents in grades 9-12 with persistent, elevated mental health symptoms and associated distress/impairment. Participants will receive either a brief problem-solving intervention delivered over 3 weeks by lay counsellors (intervention) or enhanced usual care comprised of problem-solving booklets (control). Self-reported adolescent mental health symptoms and idiographic problems will be assessed at 6 weeks (co-primary outcomes) and again at 12 weeks post-randomization. In addition, adolescent-reported distress/impairment, perceived stress, mental wellbeing, and clinical remission, as well as parent-reported adolescent mental health symptoms and impact scores, will be assessed at 6 and 12 weeks post-randomization. We will also complete a parallel process evaluation, including estimations of the costs of delivering the interventions. An embedded recruitment trial will apply a stepped-wedge, cluster (class)-randomized controlled design in 70 classes across the six schools. This will evaluate the added effect of a classroom-based sensitization intervention over and above school-level sensitization activities on the primary outcome of referral rate into the host trial. Other outcomes will be the proportion of referrals eligible to participate in the host trial, proportion of self-generated referrals, and severity and pattern of symptoms among referred adolescents in each condition. Power calculations were undertaken separately for each trial. A detailed statistical analysis plan will be developed separately for each trial prior to unblinding. DISCUSSION: Both trials were initiated on 20 August 2018. A single research protocol for both trials offers a resource-efficient methodology for testing the effectiveness of linked procedures to enhance uptake and outcomes of a school-based psychological intervention for common adolescent mental health problems. TRIAL REGISTRATION: Both trials are registered prospectively with the National Institute of Health registry ( www.clinicaltrials.gov ), registration numbers NCT03633916 and NCT03630471 , registered on 16th August, 2018 and 14th August, 2018 respectively).

RESUMEN

BACKGROUND: Mental health problems are leading contributors to the global disease burden in adolescents. This study aims to highlight (1) salient context-specific factors that influence stress and coping among school-going adolescents across two urban sites in India; and (2) potential targets for preventing mental health difficulties. METHODS: Focus group discussions were undertaken with a large sample of 191 school-going adolescent boys and girls aged 11-17 years (mean = 14 years), recruited from low- and middle-income communities in the predominantly urban states of Goa and Delhi. Framework analysis was used to identify themes related to causes of stress, stress reactions, impacts and coping strategies. RESULTS: Proximal social environments (home, school, peers and neighborhood) played a major role in causing stress in adolescents' daily lives. Salient social stressors included academic pressure, difficulties in romantic relationships, negotiating parental and peer influences, and exposure to violence and other threats to personal safety. Additionally, girls highlighted stress from having to conform to normative gender roles and in managing the risk of sexual harassment, especially in Delhi. Anger, rumination and loss of concentration were commonly experienced stress reactions. Adolescents primarily used emotion-focused coping strategies (e.g., distraction, escape-avoidance, emotional support seeking). Problem-focused coping (e.g., instrumental support seeking) was less common. Examples of harmful coping (e.g., substance use) were also reported. CONCLUSIONS: The development of culturally sensitive and age-appropriate psychosocial interventions for distressed adolescents should attend to the challenges posed by home, school, peer and neighborhood environments. Enhancements to problem- and emotion-focused strategies are needed in order to bolster adolescents' repertoire of adaptive coping skills in stressful social environments.

RESUMEN

The presynaptic protein, α-synuclein (α-syn), has been shown to play a crucial role in multiple neurodegenerative diseases, such as Parkinson's disease (PD), Alzheimer's disease (AD), and dementia with Lewy bodies (DLB). The three major domains of α-syn protein were shown to govern its membrane interaction, protein fibrillation, and chaperone activity. So far, four different alternatively spliced isoforms of α-syn, which lack either exon 3 (syn-126) or exon 5 (syn-112) or both (syn-98) resulting in altered function of the proteins, have been identified. In the present study, we have identified the smallest isoform of α-syn due to the skipping of exons 3 and 4 generating a 238 bp transcript. Due to the presence of a premature stop codon, the 238 bp transcript generated a 41 aa N-terminal peptide instead of the 78 aa protein, which is secreted into the extracellular medium when overexpressed in cells. The presence of 41-syn was initially noticed in the substantia nigra of PD autopsy tissues, as well as in cells undergoing oxidative stress. In vitro studies inferred that 41-syn neither aggregates nor alters the aggregation propensity of either WT or 112-syn. Overexpression of 41-syn or treatment of cells with 41-syn peptide did not affect cell viability. However, PC-12 cells treated with 41-syn exhibited a time and dose dependent enhancement in the cellular uptake of dopamine. Based on the physiological role of the N-terminal region of α-syn in modulating membrane trafficking events, we believe that the identification of 41-syn may provide novel impetus in unraveling the physiological basis of alternative splicing events in governing PD pathophysiology.

RESUMEN

Abnormal oligomerization and aggregation of α-synuclein (α-syn/WT-syn) has been shown to be a precipitating factor in the pathophysiology of Parkinson's disease (PD). Earlier observations on the induced-alternative splicing of α-syn by Parkinsonism mimetics as well as identification of region specific abnormalities in the transcript levels of 112-synuclein (112-syn) in diseased subjects underscores the role of 112-syn in the pathophysiology of PD. In the present study, we sought to identify the aggregation potential of 112-syn in the presence or absence of WT-syn to predict its plausible role in protein aggregation events. Results demonstrate that unlike WT-syn, lack of 28 aa in the C-terminus results in the loss of chaperone-like activity with a concomitant gain in vulnerability to heat-induced aggregation and time-dependent fibrillation. The effects were dose and time-dependent and a significant aggregation of 112-syn was evident at as low as 45 °C following 10 min of incubation. The heat-induced aggregates were found to be ill-defined structures and weakly positive towards Thioflavin-T (ThT) staining as compared to clearly distinguishable ThT positive extended fibrils resulting upon 24 h of incubation at 37 °C. Further, the chaperone-like activity of WT-syn significantly attenuated heat-induced aggregation of 112-syn in a dose and time-dependent manner. On contrary, WT-syn synergistically enhanced fibrillation of 112-syn. Overall, the present findings highlight a plausible cross-talk between isoforms of α-syn and the relative abundance of these isoforms may dictate the nature and fate of protein aggregates.

RESUMEN

Several novel molecules, 1-(3'-(9H-carbazol-4-yloxy)-2'-hydroxypropyl)-3-aryl-1H-pyrazole-5-carboxylic acid derivatives 3a-g were synthesized and screened to evaluate their cytotoxicity against cancer cells in vitro. The compounds 3a-g has been prepared by the reaction of ethyl 3-aryl-1H-pyrazole-5-carboxylate with 4-oxiranylmethoxy-9H-carbazole in moderate to excellent yields. The cytotoxicity of synthesized compounds was evaluated by a SRB (sulforhodamine B) assay against cancer cell such as SK-N-SH human neuroblastoma (NB), human A549 lung carcinoma, human breast cancer MCF-7 cell lines. The results showed that seven compounds can suppress SK-N-SH tumor cancer cell growth. Among them, compound 3d was the most effective small molecule in inhibiting SK-N-SH cell growth.
