Abstract Background Physical health needs of disaster victims take priority over mental health needs in post-disaster scenario, assessments and interventions for latter needs are done only for a shorter duration. The caregivers of the victims also bore the brunt of the disaster and their mental health needs are seldom examined and addressed. Unable to find any literature examining the mental health needs of caregivers of the endosulfan disaster victims in India, the study was planned with the objectives of assessing the prevalence and predictors of psychological distress, its relation to the level of impact, disability as well as quality of life among the caregivers of the victims of endosulfan disaster in the State of Kerala, India after 20 years. Method It was a cross-sectional community-based study among 400 the caregivers of the victims of endosulfan disaster. Demographic details, distress, impact, disability and quality of life were measured using instruments such as Family Schedule, Self-Reporting Questionnaire, Impact of Events Scale, World Health Organization Disability Assessment Schedule 2.0 and World Health Organization Quality of Life Scale, respectively. Results The estimated psychological distress among the caregivers of the endosulfan disaster victims was 48.7%. Distressed caregivers were found to have significant higher impact (t = − 12.12, p

Osteoblastic and chemical responses to Poly (ether ether ketone) (PEEK) material have been improved using a variety of low-temperature plasmas (LTPs). Surface chemical properties are modified, and can be used, using low-temperature plasma (LTP) treatments which change surface functional groups. These functional groups increase biomineralization, in simulated body fluid conditions, and cellular viability. PEEK scaffolds were treated, with a variety of LTPs, incubated in simulated body fluids, and then analyzed using multiple techniques. First, scanning electron microscopy (SEM) showed morphological changes in the biomineralization for all samples. Calcein staining, Fourier transform infrared spectroscopy (FTIR), and X-ray photoelectron spectroscopy (XPS) confirmed that all low-temperature plasma-treated groups showed higher levels of biomineralization than the control group. MTT cell viability assays showed LTP-treated groups had increased cell viability in comparison to non-LTP-treated controls. PEEK treated with triethyl phosphate plasma (TEP) showed higher levels of cellular viability at 82.91% ± 5.00 (n = 6) and mineralization. These were significantly different to both the methyl methacrylate (MMA) 77.38% ± 1.27, ethylene diamine (EDA) 64.75% ± 6.43 plasma-treated PEEK groups, and the control, non-plasma-treated group 58.80 ± 2.84. FTIR showed higher levels of carbonate and phosphate formation on the TEP-treated PEEK than the other samples; however, calcein staining fluorescence of MMA and TEP-treated PEEK had the highest levels of biomineralization measured by pixel intensity quantification of 101.17 ± 4.63 and 96.35 ± 3.58, respectively, while EDA and control PEEK samples were 89.53 ± 1.74 and 90.49 ± 2.33, respectively. Comparing different LTPs, we showed that modified surface chemistry has quantitatively measurable effects that are favorable to the cellular, biomineralization, and chemical properties of PEEK.

Materiobiology is an emerging field focused on the physiochemical properties of biomaterials concerning biological outcomes which includes but is not limited to the biological responses and bioactivity of surface-modified biomaterials. Herein, we report a novel in vitro characterization platform for characterizing nanoparticle surface-modified 3D printed PLA scaffolds. We have introduced innovative design parameters that were practical for ubiquitous in vitro assays like those utilizing 96 and 24-well plates. Subsequently, gold and silica nanoparticles were deposited using two low-temperature plasma-assisted processes namely plasma electroless reduction (PER) and dusty plasma on 3D scaffolds. Materiobiological testing began with nanoparticle surface modification optimization on 96 well plate design 3D scaffolds. We have employed 3D laser confocal imaging and scanning electron microscopy to study the deposition of nanoparticles. It was found that the formation and distribution of the nanoparticles were time-dependent. In vitro assays were performed utilizing an osteosarcoma (MG-63) cell as a model. These cells were grown on both 96 and 24 well plate design 3D scaffolds. Subsequently, we performed different in vitro assays such as cell viability, and fluorescence staining of cytoskeletal actin and DNA incorporation. The actin cytoskeleton staining showed more homogeneity in the cell monolayer growing on the gold nanoparticle-modified 3D scaffolds than the control 3D PLA scaffold. Furthermore, the mineralization and protein adsorption experiments conducted on 96 well plate design scaffolds have shown enhanced mineralization and bovine serum albumin adsorption for the gold nanoparticle-modified scaffolds compared to the control scaffolds. Taken together, this study reports the efficacy of this new in vitro platform in conducting more reliable and efficient materiobiology studies. It is also worth mentioning that this platform has significant futuristic potential for developing as a high throughput screening platform. Such platforms could have a significant impact on the systematic study of biocompatibility and bioactive mechanisms of nanoparticle-modified 3D-printed scaffolds for tissue engineering. It would also provide unique ways to investigate mechanisms of biological responses and subsequent bioactive mechanisms for implantable biomaterials. Moreover, this platform can derive more consistent and reliable in vitro results which can improve the success rate of further in vivo experiments. [ABSTRACT FROM AUTHOR]

Background: Individuals with opioid dependence experience stigma and discrimination. Stigma can potentially reduce treatment-seeking and negatively affect treatment outcomes. We aimed to study the course of stigma and its correlates among patients receiving opioid agonist treatment (OAT). Methods: We recruited 51 subjects (aged between 18 and 45 years) registered in the OAT clinic from February to September 2019. We excluded subjects dependent on alcohol and other drugs (except for cannabis and tobacco), with severe mental illness, intellectual disability, and organic brain disease. We assessed the internalized and enacted stigma and quality of life at the treatment entry and after 3 months. Relationship of stigma with quality of life, socio-demographic, and other clinical variables were examined at the treatment entry. Results: Mean age of the subjects was 26.7 (± 5) years. At the end of three months, 33 (64.7%) patients were retained in the treatment. Internalized stigma correlated negatively with the social and environmental domains of quality of life. The strength of the correlations was modest. No significant correlation was found between demographic and clinical variables and internalized stigma and enacted stigma scores. Both internalized and enacted stigma scores reduced significantly at 3 months follow-up. The significance levels were retained even after controlling for the baseline quality of life scores. Stigma at the treatment entry did not predict early dropout. Conclusion: Despite higher severity at the treatment entry, the level of internalized and enacted stigma reduced significantly within three months of an outpatient-based OAT program.

Background: Despite the magnitude and impact of co-occurring physical and substance use disorders (SUDs) and evidence of effectiveness of integrated care, the training for management of comorbidities has been neglected. Our objective was to examine the effectiveness of 1-day continuing medical education (CME) in this area on participants' perceived and objective knowledge and skills. Materials and Methods: It was a cross-sectional study of CMEs conducted in a tertiary care center with a pre-post assessment design. Assessment included rating perceived knowledge and skill on a five-point scale and objective multiple-choice questions. Subjective feedback on qualitative aspects of the CME was taken. Out of total 154 participants, 69 completed pre-post assignments that included interactive lectures through multimodal presentations and problem-based learning. Pre-post comparisons were done by paired t-test and Wilcoxon signed-rank test. Results: Pre-CME assessment showed low mean scores (4.04 [1.75]) in objective (assessment to be added) and limited perceived knowledge and ability. However, objective knowledge assessment showed a significant improvement (P < 0.001) after the CME. Perceived knowledge and skills showed a significant positive (P < 0.001, all comparisons) change in all the four (CME-1) and seven (CME-2) domains assessed. CME was perceived to be excellent in terms of the practical value of material (60.3%), able to meet its stated objectives (60.3%), quality of instructions (58.8%), and organization of material (60.3%). Conclusion: CME is a viable option for training of psychiatrists to address the unmet need for treating co-occurring physical and SUDs. Future studies with experimental designs should determine the effectiveness of the components of CMEs.

Cannabis misuse and opioid use disorder (OUD) are highly comorbid but under-treated and associated with poorer outcomes. This paper reports a double-blind, parallel-group randomized controlled trial to determine the efficacy of single-session, clinician-delivered screening and brief intervention (SBI) for reducing cannabis risk. The primary outcome was the cannabis-specific Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) scores, measured at three-month post-intervention. The secondary objectives were to determine the efficacy of SBI in reducing the frequency of cannabis use, in risk transition from moderate to low risk, and in prescription and non-prescription opioid use. One hundred forty-three participants were randomly allocated to receive either SBI (n = 72) or control (n = 71) interventions. We performed Per-protocol (PP) (n = 125) and Intention-to-treat (ITT) analysis (n = 143). We adjusted our analysis for age, sex, and baseline ASSIST score. The ITT showed that the SBI group had a significant reduction (F = 39.46, p <.001, Effect size 0.22) in the mean ASSIST at follow-up. PP analyses too revealed a similar positive effect of SBI (F = 53.1; p <.001, Effect size 0.31). At follow-up, the SBI group had a higher number of days of cannabis abstinence. Care providers and policymakers may consider SBI for cannabis use in individuals on medications for OUD. [ABSTRACT FROM AUTHOR]

This study was conducted to find out the effectiveness of the Direct Benefit Transfer (DBT) Programme in satisfying older adults 'food needs. For this purpose out of about 377 Public Distribution System (PDS) shops only 20 shops, 10 from urban areas and 10 from rural areas were selected for this study. From each shop 8 older adult respondents, a total of 160, were selected randomly for data collection. However, 8 respondents were omitted because of a lack of required data, and therefore, a total of 152 elderly respondents were finally selected for the study. An interview schedule was used for data collection. The study revealed that rural older adults have higher odds of preference for food rations as compared to urban counterparts. Scheduled caste older adults have higher odds of preference for food rations as compared to 'other 'categories. The daily wage labour has higher odds of preference for food rations as compared to other job categories. These findings stress a careful policymaking is required on food security concerns of older adults. [ABSTRACT FROM AUTHOR]

The geriatric population of India accounts more than six per cent of the total population. The number of elderly in Kerala is expected to reach 7.2 million by 2021 and 11.9 millions in 2051. The present study was conducted to (a) assess the level of depressive symptom in institutionalised elderly persons before and after the music therapy, and (b) to evaluate the effect of music therapy on depressive symptoms in elderly. An experimental research design with a one group pre-test post-test design was adopted. The purposive sample consisted of 40 elderly with depressive symptom. The tools used were (a) a proforma to collect socio-demographic data, (b) Geriatric Depression Scale, (c) Mini Mental Status Examination, and (d) Beck’s Depression Inventory. Each of the selected samples was given music therapy through individual walkman for 30 minutes in the evening hours for a regular period of 21 days. Post test was conducted a week after the completion of this exercise. There was a significant reduction in the depressive symptoms before and after the experiment (t=3.65, p

Introduction: We examined the feasibility and acceptability of digital screening and brief intervention (d‐SBI) for alcohol misuse in college students; the effectiveness of d‐SBI was our secondary outcome. We also explored the barriers and facilitators of d‐SBI. Methods: The study design is a mixed‐methods, pilot, and cluster randomized trial. Five colleges from a northern city in India were randomly allocated to d‐SBI and control groups. One hundred and ninety‐one students were screened, and 25 (male = 23 and female = 2) participants (age 19.62 ± 2.58 years) fulfilled eligibility. All participants completed follow‐up assessments at 3 months. In‐depth interviews were done with 11 participants. Alcohol Use Disorder Identification Test (AUDIT) based screening brief intervention was provided on a web portal‐ or mobile application in the d‐SBI group. The control group received digital screening and brief education. Direct questions and usage statistics assessed the measurement acceptability of the intervention. We compared the change in AUDIT scores in the intervention groups over 3 months post‐intervention. Thematic analyses of transcripts of interviews were done by inductive coding. Results: Most participants reported that d‐SBI was user‐friendly (80%), advice was appropriate (80%), and perceived it to be useful (72%). Ninety‐six percent of users, who logged in, completed screening. There was a significant decrease in AUDIT scores both in d‐SBI (p <.001) and control groups (p <.001). Time and group significantly affected the mean AUDIT score, but time × group interaction was non‐significant. Thematic analysis revealed six overarching themes. Conclusions: Digital SBI for alcohol misuse is acceptable, feasible, and possibly effective among college students from low‐resource settings. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]
