Chitotriosidase, a biomarker of amyotrophic lateral sclerosis, accentuates neurodegeneration in spinal motor neurons through neuroinflammation.

BACKGROUND: Cerebrospinal fluid from amyotrophic lateral sclerosis patients (ALS-CSF) induces neurodegenerative changes in motor neurons and gliosis in sporadic ALS models. Search for identification of toxic factor(s) in CSF revealed an enhancement in the level and enzyme activity of chitotriosidase (CHIT-1). Here, we have investigated its upregulation in a large cohort of samples and more importantly its role in ALS pathogenesis in a rat model. METHODS: CHIT-1 level in CSF samples from ALS (n = 158), non-ALS (n = 12) and normal (n = 48) subjects were measured using ELISA. Enzyme activity was also assessed (ALS, n = 56; non-ALS, n = 10 and normal-CSF, n = 45). Recombinant CHIT-1 was intrathecally injected into Wistar rat neonates. Lumbar spinal cord sections were stained for Iba1, glial fibrillary acidic protein and choline acetyl transferase to identify microglia, astrocytes and motor neurons respectively after 48 h of injection. Levels of tumour necrosis factor-α and interleukin-6 were measured by ELISA. FINDINGS: CHIT-1 level in ALS-CSF samples was increased by 20-fold and it can distinguish ALS patients with a sensitivity of 87% and specificity of 83.3% at a cut off level of 1405.43 pg/ml. Enzyme activity of CHIT-1 was also 15-fold higher in ALS-CSF and has a sensitivity of 80.4% and specificity of 80% at cut off value of 0.1077989 µmol/µl/min. Combining CHIT-1 level and activity together gave a positive predictive value of 97.78% and negative predictive value of 100%. Administration of CHIT-1 increased microglial numbers and astrogliosis in the ventral horn with a concomitant increase in the levels of pro-inflammatory cytokines. Amoeboid-shaped microglial and astroglial cells were also present around the central canal. CHIT-1 administration also resulted in the reduction of motor neurons. CONCLUSIONS: CHIT-1, an early diagnostic biomarker of sporadic ALS, activates glia priming them to attain a toxic phenotype resulting in neuroinflammation leading to motor neuronal death.

Incidence of Deep Vein Thrombosis in Neurointensive Care Unit Patients-Does Prophylaxis Modality Make Any Difference?

BACKGROUND AND AIMS: To determine the incidence of upper and lower limb deep vein thrombosis (DVT) using ultrasonography (USG) in adult patients admitted to neuro-medical and neurosurgical intensive care unit (ICU). MATERIALS AND METHODS: In this prospective observational study, patients admitted to the medical and surgical neuro-ICU and remained in the ICU for more than 48 hours were recruited. All patients were clinically examined for DVT. Basilic and axillary veins in the upper limbs and popliteal and femoral veins in the lower limbs were screened for DVT using USG. USG examination was performed on the day of admission to ICU and thereafter every 3rd day till discharge from ICU or death. Intermittent pneumatic compression (IPC) stockings were applied to the lower limbs to all the patients in both ICUs. Unfractionated heparin (UFH) was given subcutaneously to neuromedical ICU patients, while in surgical ICU, it was left to the discretion of the neurosurgeons. RESULTS: A total of 130 adult patients were admitted to the ICU during the 8 month study period. Thirty patients were excluded and the remaining 98 patients' (38 in medical and 60 in surgical ICU) data were analyzed. None of the 38 medical ICU patients developed DVT, while in neurosurgical ICU, 4 out of 60 patients developed DVT. CONCLUSION: A combination of UFH and IPC stockings were effective in minimizing the DVT in neuromedical ICU patients. In surgical patients, through IPC stockings were effective, UFH can be considered for patients with intracranial malignancy.

Hydroxyethyl starch and kidney function: A retrospective study in patients undergoing therapeutic plasma exchange.

PURPOSE: Hydroxyethyl starch (HES) and albumin are used as replacement fluids during therapeutic plasma exchange (TPE). HES solutions are no longer recommended in critically ill patients due to its effect on kidneys and coagulation. In this retrospective study, we tried to look at the association between cumulative HES administration and kidney function in patients undergoing TPE. METHODS: Transfusion medicine department register was scrutinized to identify adult patients who had completed at least 5 cycles of TPE during the period June 2014-May 2015. Patient demographics, indication for TPE, amount of plasma removed, amount of colloid administered, adverse events and vascular access details were collected. Electronic hospital database was scrutinized to retrieve lab parameters, including blood urea and serum creatinine (before and after 5 cycles of TPE) and platelet count. Baseline renal parameters were compared with post TPE values using Wilcoxon signed rank test. A p value <0.05 was kept as significant. RESULTS: Of the 593 patients who received TPE during the study period, 104 patients fulfilled the inclusion criteria. Forty-five patients out of 104 received TPE in the intensive care unit. All patients received 2500 ml of HES during the study period. Blood urea and serum creatinine values, when compared to baseline, significantly decreased after 5 cycles of TPE (p = 0.004, p = 0.001, respectively). CONCLUSION: Blood urea and serum creatinine, used as markers of renal function, improved in patients requiring multiple doses of HES solutions during TPE. Further studies using novel renal biomarkers are required to examine whether HES induces any structural damage to kidneys.

Duration of Pupillary Unresponsiveness to Light: A Physiological Adjunct to Electroencephalography and Motor Seizure Duration Monitoring During Electroconvulsive Therapy.

BACKGROUND: During electroconvulsive therapy (ECT) sessions, we observed that the time taken for the return of pupillary response to light (ROPL) outlasted both the electroencephalography (EEG) and the motor seizure duration after the delivery of the electrical stimulus to produce convulsions. OBJECTIVE: The objective of this study was to investigate whether ROPL can be used as a marker of cessation of seizure activity in the brain after ECT and also to study the effect of atropine premedication on seizure activity during ECT. METHODS: Forty-one patients underwent 82 sessions of ECT in a cross-over design study. The duration of motor seizure, EEG seizure, and time for ROPL was observed and compared. RESULTS: The ROPL consistently outlasted EEG and motor seizures; the difference in their mean durations was statistically significant P < 0.05. There was good correlation among the 3 parameters. Atropine premedication did not alter the seizure activity and ROPL after ECT. CONCLUSIONS: The ROPL after ECT stimulus is a good bedside monitor for termination of seizure activity and can be a valuable adjunct to surface EEG in monitoring the duration of epileptic activity after delivery of ECT.

Proinflammatory chemokines are major mediators of exuberant immune response associated with Influenza A (H1N1) pdm09 virus infection.

In India, the case fatality ratio of the pandemic A (H1N1) pdm09 influenza was relatively higher when compared to seasonal Influenza A infection. Hypercytokinemia or "cytokine storm" has been previously implicated in the pathogenesis of other influenza viruses. The present study was undertaken to compare the cytokine profiles of A (H1N1) pdm09 influenza and seasonal H3 infection in Indian population and to correlate the findings with disease severity. Plasma levels of 18 cytokines/chemokines were measured by flow-cytometry using a bead based assay in patients infected with A (H1N1) pdm09 virus (n = 96) and Influenza A seasonal H3 virus (n = 30) categorised into mild, moderate, and severe groups along with healthy controls (n = 36). There was an overall trend indicating an exuberant cytokine/chemokine response in A (H1N1) pdm09 as compared to seasonal H3 influenza, which was more evident in severe cases, suggesting a role for these cytokines/chemokines in the pathogenesis of A(H1N1) pdm09. Increased levels of CXCL-8/IL-8, IL-10, IL-6, and IL-17A were seen in both A(H1N1) pdm09 influenza and seasonal H3 cases when compared to healthy controls. However, dysregulated production of proinflammatory chemokines was seen more pronounced in A (H1N1) pdm09 influenza cases as compared to seasonal H3 cases. This study has brought forth the potential role of chemokines as prognostic indicators of disease severity and outcome. Further research on modulating the host immune response to limit severity of the disease could help in the treatment and management of influenza.

Effect of Atropine Premedication on Cardiac Autonomic Function During Electroconvulsive Therapy: A Randomized Crossover Study.

OBJECTIVES: Electroconvulsive therapy (ECT) results in significant cardiovascular changes. The acute cardiac autonomic changes during ECT remain unexplored. The primary objective of this study was to compare autonomic dysfunction with and without atropine premedication during ECT and secondarily to evaluate dysautonomia across psychiatric diagnoses before and after ECT. METHODS: In this crossover study, 41 psychiatric patients were monitored during 82 ECT sessions. Patients were randomized either to receive atropine or not to receive atropine during their second ECT session and were crossed over during their third session. Heart rate, blood pressure, and oxygen saturation were continuously monitored from stimulus application until 300 seconds after ECT. Demographic characteristics and ANSiscope indices derived pre- and post-ECT were collected. RESULTS: Autonomic dysfunction (%) before ECT was similar between atropine and no-atropine sessions (32.4 ± 15.7 vs 32.8 ± 16.7; 95% confidence interval, -7.6 to 6.7; P = 0.90) but increased significantly after ECT to 60.9 ± 16.3 and to 47.0 ± 17.3, respectively, and this difference was significant (95% confidence interval, 6.5-21.3; P < 0.001). There was no difference in the autonomic function across psychiatric diagnoses both before (P = 0.07) and after ECT (P = 0.12). CONCLUSIONS: Cardiac autonomic dysfunction worsens after ECT in patients with psychiatric illnesses and to a significantly greater extent with atropine premedication. The degree of dysautonomia is similar across various psychiatric diagnoses both before and after ECT. Atropine premedication during ECT should be restricted to select patients susceptible to bradyarrhythmia and could be avoided in others.

Prognostic value of FOUR and GCS scores in determining mortality in patients with traumatic brain injury.

BACKGROUND: The Glasgow Coma Scale (GCS) is considered the gold standard for assessment of unconsciousness in patients with traumatic brain injury (TBI) against which other scales are compared. To overcome the disadvantages of GCS, the Full Outline Of Unresponsiveness (FOUR) score was proposed. We aimed to compare the predictability of FOUR score and GCS for early mortality, after moderate and severe TBI. METHODS: This is a prospective observational study of patients with moderate and severe TBI. Both FOUR and GCS scores were determined at admission. The primary outcome was mortality at the end of 2 weeks of injury. RESULTS: A total of 138 (117 males) patients were included in the study. Out of these, 17 (12.3 %) patients died within 2 weeks of injury. The mean GCS and FOUR scores were 9.5 (range, 3-13) and 11 (0-16), respectively. The total GCS and FOUR scores were significantly lower in patients who did not survive. At a cut-off score of 7 for FOUR score, the AUC was 0.97, with sensitivity of 97.5 and specificity of 88.2 % (p < 0.0001). For GCS score, AUC was 0.95, with sensitivity of 98.3 % and specificity of 82.4 % with cut-off score of 6 (p < 0.0001). The correlation coefficient was 0.753 (p < 0.001) between the GCS and FOUR scores. CONCLUSIONS: The predictive value of the FOUR score on admission of patients with TBI is no better than the GCS score.

Identifying psychological distress in elderly seeking health care.

BACKGROUND: Psychological distress in the elderly with various illness conditions often goes unrecognized. Since psychological distress is treatable, it is important to recognize it at the earliest to enhance recovery. This is an interim analysis of screening data of the elderly seeking health care in a hospital in India, with a focus on the 12-item General Health Questionnaire (GHQ-12), a screening instrument for psychological distress and a rationale for a higher cutoff score in help seeking elderly. MATERIALS AND METHODS: A retrospective analysis of screening data of psychological distress using GHQ-12 in the elderly seeking care for neuropsychiatric conditions was carried out. Traditionally, ≥2 is considered positive for distress by GHQ-12. Receiver Operating Characteristic (ROC) curve was used to define new cutoff points for psychological distress. RESULTS: At ≥2, 2443 (50%) of the elderly screened were recognized to be psychologically distressed. Using an ROC and optimum sensitivity and specificity measures, a cutoff score of ≥4 was observed to detect 30% of the elderly who had diagnosable mental health disorders. Female sex, illiteracy, and multiple co-morbidities were the factors that were associated with higher cutoff scores on GHQ-12 proposed here and psychiatric morbidity thereof. CONCLUSION: There is greater psychological distress among the elderly seeking health care. Hence, it is important to screen them and identify those at higher risk. Using a higher cutoff score with a standardized instrument like GHQ-12 indicated that it was statistically valid to identify those elderly with higher distress in a busy out-patient setting.

Computed tomography-based classification of axis vertebra: choice of screw placement.

PURPOSE: The purpose of the study was to: (1) introduce a new CT-based parameter: free facet area and provide its normative data; (2) standardize the method of measuring isthmus width and height of the axis vertebra; (3) propose a new grading system to predict the difficulty in inserting transarticular and C2 pedicle screws. METHODS: Spiral CT scans of 47 adult dry axis vertebrae were studied. The methods of measuring isthmus width, isthmus height and free facet area are described. RESULTS: The mean isthmus width was 5.04 mm on the right side and 5.42 mm on the left side. The mean isthmus height was 5.21 mm on the right side and 5.45 mm on the left side. Mean free facet area was 61.23 % on the right side and 70.18 % on the left side. A novel grading system is proposed on the basis of these three parameters. As per this grading system, 40.4 % of the sides were found to be difficult for transarticular and 24.5 % sides for C2 pedicle screw insertion (total score 2, 3, 4). A Management protocol is suggested on the basis of the grading system. CONCLUSION: Inserting a transarticular screw was more frequently difficult as compared to pedicle screw. A new CT-based parameter (free facet area) and an efficient grading have been proposed to help surgeons choose the appropriate screw options, appreciate the complex anatomy of this region and compare data across various studies.

Levels of work stress among information technology professionals during COVID-19 pandemic in an Indian metropolis.

Introduction: Amid the ongoing Non-Communicable Disease and COVID-19 pandemic, understanding prevalence and characteristics associated with work stress is vital from a health and economic perspective, more so among information technology (IT) professionals. Objective: To estimate the prevalence and factors associated with work stress among IT professionals during the coronavirus disease 2019 (COVID-19) pandemic in Bengaluru, India. Materials and Methods: A cross-sectional study was undertaken on a convenient sample of 356 IT professionals in Bengaluru, India, between September 2020 and March 2021 to assess work stress. The weblink to TAWS-16 (Tool to Assess and classify Work Stress) was provided for IT employees to self-report their experience of work-related stressors and coping abilities in the past 6 months. The prevalence and specific prevalence of work stress were calculated. Multi-variate logistic regression was conducted to identify factors associated with work stress. Ethical clearance was obtained from the Institutional Ethics committee, National Institute of Mental Health and Neurosciences, Bengaluru. Informed consent was obtained from study subjects. Results and Conclusion: The prevalence of work stress among IT professionals was 17.7% during the COVID19 pandemic, with higher rates among employees aged 31 years and above, among female employees, and among employees with 4-7 years of work experience. More than 80% of the professionals experienced deadline pressures, long working hours, regular multi-tasking, and difficulty in maintaining work-life balance. Based on the results, it is recommended to integrate work-stress assessment in periodical medical examination of IT employees from a health promotion and productivity improvement perspective.

Clinicoradiological Features and Long-term Cognitive and Functional Outcome in Patients with Deep Cerebral Venous Thrombosis.

Background: Deep cerebral venous thrombosis (DCVT) can have long-term functional and cognitive sequelae. Although literature exists on cognitive impairment after arterial stroke, cognitive sequelae after cerebral venous thrombosis (CVT) are much less studied. Methods: Clinical records of 29 patients diagnosed with DCVT were reviewed. The Modified Telephonic Interview for Cognitive Status (TICS-M) was adapted and validated in the regional language (Kannada) and applied to 18 patients with DCVT, at a mean follow-up duration of 5.32 years. Screening for depression was done via telephonic Patient Health Questionnaire-9 (PHQ-9)-Kannada version, and functional status was screened by applying the modified Rankin Scale (mRS). Results: DCVT had a mortality rate of 10.34% due to acute complications. mRS scores of 0-1 were achieved at follow-up in all patients who survived. Receiver operating characteristic (ROC) analysis revealed a cutoff of ≤44.5 (maximum score of 49) for the diagnosis of cognitive impairment via TICS-M (Kannada version) in DCVT patients. Evidence of cognitive dysfunction was seen in eight patients (42.10%), and three patients (16.66%) had evidence of depression. Conclusions: Survivors of acute DCVT can potentially have long-term cognitive sequelae. Screening for cognitive dysfunction, depression, and functional status can be effectively done using telephonically applied scales that are adapted to the local language. Neuropsychological evaluation and early cognitive rehabilitation can be initiated for patients in whom deficits are identified on cognitive screening.

Suicide attempts in schizophrenia - A large retrospective cohort study from a tertiary care psychiatry centre in India.

The extent of variability in identified risk factors for suicide attempts (SA) in schizophrenia limits their generalization. This study aimed to identify the rates and associated correlates of SA in schizophrenia by reviewing a large cohort (n=500). Nearly one-fourth had a history of SA, which was independently associated with a family history of SA, more inpatient admissions, and better long-term treatment response. These findings highlight the complex interaction between biological factors influencing SA and illness determinants in schizophrenia. Furthermore, they reinforce the need for future research to unravel the association between suicide vulnerability and the pathophysiology of schizophrenia to attenuate morbidity and mortality associated with the same.

Study on awareness and management based health action using video intervention (SAMBHAV) for postpartum depression among mothers attending immunisation clinic in a tertiary medical college hospital: Study protocol.

INTRODUCTION: Pregnancy exerts a detrimental effect on women's mental health. Maternal mental health is considered as one of the public health concerns as it impacts the health of both mother and the child. One in five people in developing countries experience serious mental health issues during pregnancy and after giving birth. In India, postpartum depression (PPD) affects 22% of women, according to a research by WHO. The available data on mental health literacy among women, showed that only 50.7% of the postpartum mothers who were attending paediatric tertiary care centres had adequate knowledge about PPD. It is crucial to diagnose early and adequately manage postpartum depression to avoid long-term consequences. It is also essential to seek help and utilise the available resources and services to avoid worsening of the condition and to aid in the recovery. This demonstrates the need to promote awareness, improve help seeking, reduce stigma and treatment gap associated with PPD through educational video intervention specific to cultural context and beliefs. MATERIALS AND METHODS: This is a quasi-experimental study without a control group that attempts to improve the awareness among the mothers about postpartum depression to understand better about the condition and also its management through video intervention. The video intervention will be developed in regional language specific to the cultural context of the setting. The video script will be finalised from the findings of the available literature and also through focus group discussion among mothers and health care professionals which will be analysed qualitatively using thematic identification. The study will use a standardized Postpartum Depression Literacy Scale (PoDLIS) which will be quantitatively analysed using paired t test before and after the intervention. Repeated measures of ANOVA will also be used to analyse the changes in literacy scale scores with respect to socio demographic variables. The mothers will also be screened for PPD using Patient Health Questionnaire 9 (PHQ 9) and feedback will be collected and analysed to find the overall usefulness of video. DISCUSSION: If it becomes apparent that this video intervention is successful in raising awareness of PPD among postpartum mothers and reducing stigma, it can be used to aid early identification of mothers with PPD which can result in early management and improved health outcome for both mothers and children. The major goals of the video intervention are to raise awareness, lessen stigma, and prevent PPD through strong family support, adopting healthy lifestyles, having access to information, practising self-care, and enhancing help-seeking. TRIAL REGISTRATION: The trial is registered under the Clinical Trial Registry- India (CTRI) (CTRI/2023/03/050836). The current study adheres to the SPIRIT Guidelines [See S1 Checklist: SPIRIT Guidelines].

Clinical effects of a yoga-based intervention for patients with schizophrenia - A six-month randomized controlled trial.

BACKGROUND: Yoga has shown promise as an add-on therapy for patients with schizophrenia. However, most studies have been short-term, with methodological limitations. METHODS: We conducted a six-month parallel-group randomized-controlled trial (with rater blinding) to evaluate the effectiveness of a yoga-based intervention in improving symptoms and quality of life in patients with schizophrenia. We recruited 110 patients from an urban tertiary hospital and a semi-urban community centre who met DSM 5 criteria for schizophrenia and were on stable medication for at least six weeks. Participants were randomly assigned to either yoga add-on therapy (YT) or treatment-as-usual (TAU) groups. Clinical assessments were conducted at baseline and at one, three and six months. The primary outcome was changes in positive/negative symptom scores and secondary outcomes included changes in quality of life, perceived stress and socio-occupational functioning. RESULTS: Intention to treat analysis with a longitudinal mixed model approach revealed a significant group-by-time interaction with the YT group showing medium effect improvements in negative symptoms (η2p = 0.06) and small effect improvements in positive symptoms (η2p = 0.012), WHOQOL-BREF quality of life [psychological well-being (η2p = 0.015) and environmental health (η2p = 0.048)] when compared to TAU. The patients successfully learned and performed yoga practices without reporting any significant adverse effects. DISCUSSION: Our findings suggest that yoga-based intervention may be a valuable adjuvant therapy for medication-stabilized patients with schizophrenia, especially in ameliorating negative symptoms and enhancing quality of life. Future controlled trials, including active physical interventions, are crucial to validate yoga's efficacy, optimize clinical use, and elucidate underlying mechanisms.

Evident stabilization of the clinical profile in HIV/AIDS as evaluated in an open label clinical trial using a polyherbal formulation.

BACKGROUND & OBJECTIVES: The complementary and alternative medicines (CAM) have not been systematically evaluated for the management of HIV/AIDS patients. In a prospective, single-site, open-label, non-randomized, controlled, pilot trial, we evaluated a polyherbal formulation (PHF) for its safety and efficacy in treating subjects with HIV-AIDS. METHODS: A total of 32 and 31 subjects were enrolled under the PHF and highly active antiretroviral treatment (HAART) arms, respectively, and followed up for a period of 24 months. Plasma viral RNA, CD4 cell count and blood chemistry were monitored at 3-month intervals. Following mid-term safety evaluation, 12 subjects from the PHF arm were shifted to HAART and were followed separately as PHF-to-HAART arm, for the rest of the period. RESULTS: The HAART arm was characterized by significant improvements in CD4 cell count (154.4 cells/µl/year, P<0.001) and reduction in plasma viral load within 3 to 6 months (-0.431+ 0.004 log 10 IU/month, P<0.001). In contrast, the PHF arm showed a profile of CD4 cell loss at remarkably slower kinetics (14.3 cells/µl/year, P=0.021) and insignificant reduction in the viral load. The PHF and HAART arms did not differ significantly in the occurrence of AIDS-related illnesses over the study period of 24 months. In the PHF-to-HAART arm, the rates of CD4 count and reduction in viral load were significant and comparable to that of the HAART group. In the PHF arm, at 1 month, a significant increase in CD4 cell count and a concomitant decrease in viral load were seen. INTERPRETATION & CONCLUSIONS: The PHF appears to have provided protection by delaying the kinetics of CD4 cell reduction. Given the several study limitations, drawing assertive inferences from the data is challenging. Future studies with a stringent study design are warranted to confirm these findings.

Face, content, criterion and construct validity assessment of a newly developed tool to assess and classify work-related stress (TAWS- 16).

INTRODUCTION: As work-stress, is associated with Non Communicable Diseases, and decreased work productivity, health and economic benefits are expected from periodic work-stress screening among employees using valid and reliable tools. Tool to Assess and classify Work Stress (TAWS- 16) was developed to overcome limitations in existing work-stress assessment tools in India. This study aims to test face, content, criterion and construct validity of TAWS- 16 in a sample of managerial-supervisory employees. METHODS: Nine domain experts rated face and content validity of TAWS- 16. Content validity was measured by Content Validity Indices (I-CVI, S-CVI) and Modified Kappa statistics. Empirical validity was tested by analysing data reported from 356 Information Technology (IT) professionals wherein Exploratory Factor Analysis was conducted for the assessment of Construct Validity. Self-reported data was collected in an unlinked and anonymous manner using a web-link, which was emailed to the study subjects, after initial introductory telephone or personal conversation. Criterion Validity was tested against stress sub-scale of DASS- 21. This study was approved by NIMHANS ethics committee. RESULTS: Findings revealed that TAWS- 16 has good face validity. The content validity is acceptable (CVI = 0.829). Construct Validity is appropriate as 60.8% of the total variance was explained by the factors identified in our study. Criterion Validity was moderate (Kappa Value 0.208) due to inappropriate work-stress instrument for comparison with TAWS- 16. CONCLUSIONS: Overall, TAWS- 16 demonstrated good face, content and construct validity. It measures work-stressors, coping abilities and psycho-somatic symptoms associated with work-stress. We recommend use of TAWS- 16 for periodic screening and classification of work-stress among employees.

Association of Social Network Characteristics with Substance Use among College-Going Young Adults: A Cross-Sectional Study.

Background: Family members, peers, and significant others are part of a college student's social network. This cross-sectional study aimed to Assess substance use prevalence and patterns among college students,Compare the social network characteristics of substance users (SUs) and non-users (NUs), andExplore the association of social factors with substance use. Methods: The study involved 902 students from 11 Government and aided private degree colleges. Demographic and clinical data sheet, ASSIST, and Social Network Questionnaire were used to collect the data. Results: Prevalence of substance use was 26.9% and higher among males (21.5%). Alcohol (20%) and tobacco (15.5%) were the commonly used substances. SUs' network was composed of unmarried persons (p<0.002), male members (p<0.001), and friends (p<0.001) with substance use. In contrast, the NUs' network comprised parents (p<0.016) and siblings (p<0.001). NUs had a higher number of influential members in the network, whereas SUs had more closeness with members and received higher financial support (p<0.001). Participant's age (OR 1.27), family history of substance use (OR 2.46), parents' occupation (Business: OR 1.79, being employee in the government or industry: OR 1.76),and having three substance-using members in the network (OR .211) were found to be risk factors. Conclusion: Social network has an association with substance use among college students. Social-network-based interventions may benefit them.

Reliability of a Newly Developed Tool to Assess and Classify Work-related Stress (TAWS-16) for Indian Workforce.

OBJECTIVES: Work stress is associated with non-communicable diseases, increased healthcare costs, and decreased work productivity among employees in the information technology sector. There is a need for regular work-stress screening among employees using valid and reliable tools. The Tool to Assess and Classify Work Stress (TAWS-16) was developed to overcome limitations in existing stress assessment tools in India. This study aimed to test the reliability of TAWS-16 in a sample of managerial-supervisory employees. METHODS: This observational reliability study included data from 62 employees. Test-retest and inter-method reliability were investigated using a TAWS-16 web application and interview by telephone, respectively. Kappa values and intra-class correlation coefficients were calculated. Internal consistency was assessed through Cronbach's alpha. RESULTS: For both test-retest and inter-method reliability, the agreement for both work-related factors and symptoms suggestive of work stress exceeded 80%, and all kappa values were 0.40 or higher. Cronbach's alpha for test-retest and inter-method reliability was 0.983 and 0.941, respectively. CONCLUSIONS: TAWS-16 demonstrated acceptable reliability. It measured stressors, coping abilities, and psychosomatic symptoms associated with work stress. We recommend using TAWS-16 to holistically identify work stress among employees during periodical health check-ups in India.

Relationship of personality, psychological distress, and substance use with social network characteristics of college going young adults.

Background: Causes of substance use are multifactorial. Factors such as personality, psychological distress, and the person's social ties contribute to the understanding of substance use problems of college students. Aim: The current study aimed to investigate the association between personality traits and psychological distress with ego-centric social networks of substance-using and non-using college students. Method: This cross-sectional descriptive study involved 902 undergraduate students from the government (n = 2) and government-aided (n = 9) colleges. The socio-demographic data sheet, Big Five Personality Inventory, Depression Anxiety and Stress Scale, and the semi-structured Ego-centric Social Network Questionnaire were used to collect data. Results: Of 902 participants, 26.9% of participants used substances. The mean score of anxiety (P < 0.002) and depression (P < 0.002) was significantly higher among the substance users compared with non-users. Agreeableness (P < 0.001) and conscientiousness (P < 0.001) scores were significantly higher among non-users. Depression (P < 0.01), anxiety (P < 0.01), and stress (P < 0.01) correlated positively with the total number of substance users in the network. Agreeableness (P < 0.01) and conscientiousness (P < 0.01) were positively correlated with parents and siblings in the network. Stress emerged as a predictor (OR 1.61, CI 1.09-3.04, P < 0.001) for considering substance users to the social network. Conclusion: Personality and psychological distress are associated with an individual's social network and significantly contribute to student substance use problems.
