Background: The polyurethane foam (PUF) mattress-making workers are exposed to isocyanates which are known respiratory toxicants and cause effect on pulmonary volumes and flows. Thus, the study was with a rationale to measure the changes in pulmonary flow and volumes due to isocyanates among PUF mattress-making workers. Materials and Methods: The study included 183 male workers from seven PUF making units of western and northern India. Using the interview technique as a tool for data collection, demographic and occupational details of the subjects were recorded on the predesigned and pretested pro forma. The mean of spirometric parameters was compared using one-way ANOVA and t-test. The relation between spirometric parameters and anthropometric parameters was analyzed using the correlation coefficient. Results: The spirometry showed that out of 183 participants, 165 (90.2%) subjects had normal spirometry, 13 (7.1%) had restrictive impairment, and 4 (2.2%) had obstructive impairment. All the mean spirometric values showed a declining trend with increasing age, while only forced expiratory volume in first second and forced vital capacity25%-75% showed a declining trend with increasing duration of employment. The spirometric measurements had a negative correlation with age and positive correlation with height. Conclusion: The spirometric values representing the airway flow were affected. The associated factors include age and duration of exposure.

Assam is a state in Northeast India facing floods every year which leads to human misery and devastation of nature. The objective of this review is to explore the natural and anthropogenic factors causing flood in Assam over a period of 11 years. The SCOPUS, Science Direct, and Web of Science databases were searched to identify relevant studies in Assam. The outcome of interest was to identify the natural and anthropogenic factors that contributed to the occurrence of floods in Assam from 2010 to 2020. Data were charted and reported in accordance with the \"PRISMA guidelines.\" From 1582 screened citations, 54 articles went under full-text screening, among which 35 studies were eligible for this review. Rainfall events, climate change, urbanization, deforestation, improper drainage and embankment construction contributed most. This review concludes that anthropogenic factors outweigh the natural factors for flood occurrence in Assam.

Background Stigma is a recurring challenge in epidemics, undermining disclosure, testing, and reintegration. During COVID-19 in India, little is known about how community perceptions translated into recovered participant´s experiences of stigma. Methods A multicentric qualitative study was conducted (September 2020–January 2021) across 18 districts in 7 Indian states. In depth telephone interviews were undertaken with 223 participants (136 community members, 87 recovered individuals). Data were analysed thematically using Braun and Clarke’s framework, with NVivo-assisted coding, reflexive journaling, and saturation checks to ensure rigour. Results Six major-themes were identified: fear and moralisation, institutional labelling, structural inequalities, economic and psychological harms, stigma within health-care interactions, and coping. Community fears of contagion and visible labelling (stickers, barricades, police visits) legitimised gossip and blame, which recovered participant´s described as persistent rejection, job loss, shop boycotts, and psychological distress. Stigma disproportionately affected informal workers, poorer households, and Muslim minorities, which was further fuelled by media portrayals. Coping relied on family support, while community members highlighted the role of health workers and positive media narratives in stigma reduction. Discussion Stigma during COVID-19 in India was socially produced and sustained by fear, institutional measures, and social hierarchies. These dynamics directly translated into recovered participant´s lived experiences, undermining both equity and epidemic control. Addressing stigma is therefore central to pandemic preparedness. Risk communication should avoid fear-based messaging, institutional protocols must protect confidentiality, and psychosocial support and equity monitoring should be embedded into preparedness frameworks. Highlights What is already known on this topic Stigma is a recurring challenge in epidemics, documented in HIV, TB, and Ebola. Early reports from COVID-19 highlighted stigma against health-care workers, but less is known about community and recovered participant´s experiences. What this study adds First multicentric Indian study to capture both community perceptions and recovered participant´s experiences of COVID-19 stigma. Demonstrates how fear and institutional labelling directly translated into exclusion beyond recovery, economic loss, and psychological distress. How this study might affect research, practice or policy Shows stigma is a structural determinant of epidemic response. Provides evidence for embedding stigma-sensitive communication, equity monitoring, and psychosocial support into preparedness frameworks.

Background: Polyacrylate (PA) powder dust formed in PA manufacturing units is fine sized, i.e., in nanosize. Although several previous studies reported possible significant adverse effects of nanomaterials, studies on the harmful effect of small-sized PA particles on the respiratory health of the workers are scarce. The present study was carried out to assess the effect of PA on respiratory health and lung volumes/rates among the workers of PA manufacturing unit. Materials and Methods: The present cross-sectional study included 84 workers of PA manufacturing unit. Using interview technique as a tool for data collection, demographic, occupational, and clinical details of the workers were recorded on the predesigned pro forma. This was followed by detailed clinical examination, spirometry, chest X-ray ( posteroanterior [PA] view), and high-resolution computed tomography (HRCT) examination of each worker. Results: On the basis of clinical examination, chest radiography, and HRCT, 17.9% of the workers were found to have fibrotic and cavitary changes in lung parenchyma. The production department workers had a higher proportion of respiratory morbidities as compared to supervisory or office staff. Age, gender, smoking habit, and duration of exposure were nonsignificant risk factors for respiratory morbidity. The overall mean forced vital capacity, forced expiratory volume in 1st s, Peak Expiratory Flow Rate (PEFR), (Maximal Mid Expiratory Flow Rate) MMEFR0.2-1.2, and MMEFR25%-75% were 3.19 ± 0.77 L, 2.72 ± 0.67 L, 6.82 ± 1.86 L/s, 5.79 ± 2.03 L/s, and 3.16 ± 1.19 L/s, respectively. Females and those having respiratory morbidity had significantly lower values of all spirometric parameters as compared to their counterparts. Conclusions: The workers exposed to engineered fine dust of PA may be at risk of respiratory ill-health.

Objective:There is a dearth of an appropriate standardized tool to assess neuropsychological functions in rural population, which has low literacy rates, are culturally diverse, and have limited access to healthcare resources. The NIREH Neuropsychological Battery for Rural Population (NINB-RP) is a relatively brief and easy-to-administer battery comprising multiple tests that are modified or adopted as per rural community settings to evaluate verbal learning, fine coordination, attention efficiency, executive task, concentration, and visual attention, mental flexibility, and motor coordination in rural populations. The present study aimed to examine the clinical validity and establish cut-off scores for impairment of neuropsychological functions for different age, gender, and education levels of NINB-RP in a rural community in central India.Participants and Methods:This was a prospective cross-sectional study conducted in participants aged > 18 years (n=2952, M: F=1407:1545) recruited through a stratified sampling technique from 23 randomly selected villages from central India. The data of nine neuropsychological tests [(Finger and Tweezer dexterity test (FDT, TDT); Digit Forward and Backward test (DFT, DBT); Serial subtraction test (SST); Trail Making-A and B; Finger Tapping test (FTT); and Letter Digit Substitution test, LDST)] from 215 cognitively impaired and 2737 healthy control subjects were analyzed. The tests were performed in a village school/community hall or an outdoor camp. Independent sample t-test, Chi-square test, and Receiver Operating Characteristic (ROC) curve were used to calculate the area under the curve (AUC), cut-off scores, and sensitivity (ST)/specificity (SP) values for seven conditions, i.e., gender (male vs. female), age groups (up to 49 years and above 50 years); and educational levels (illiterate, intermediate and college). For those variables where ST/SP values were lower than 0.70, a unique cut-off score was calculated for the entire sample, adjusting by age and educational levels.Results:A significant difference in mean (median) scores between the healthy control and cognitively impaired groups were observed in all tests except Trail Making A and B and LDST. The AUC for most of the tests ranged from 0.70 to 0.81, and the ST/SP values ranged from 69-73% and 65-75%, respectively. The results showed that most tests of NINB-RP reached moderate to good sensitivity and specificity for gender, age and education levels, except for DBT for females, above 50 years, and illiterate and intermediate education groups. FDT for males [AUC: 0.85 (95%CI0.80-0.91], ST/SP=76/82%] and females [(AUC=0.78 (95%CI0.74-0.82), ST/SP=71/70%], TDT for intermediate education group [AUC=0.82 (95%CI0.60-1.00), ST/SP=86/83%] and FTT for less than 49 years age group [AUC=0.75 (95%CI0.67-0.84), ST/SP=71/76%] were the most useful tests to discriminate among healthy control and cognitively impaired rural population.Conclusions:The present study is an attempt to establish the cut-off scores of a neuropsychological battery for a large rural population in the community setting. The proposed cut-off values might be helpful in clinical assessment in rural areas where clinical neuropsychology services are not readily available. NINB-RP can be a valuable tool for clinical research studies in rural communities. Further studies on similar samples in other countries need to be undertaken.

Context: After the gas tragedy on the night of December 2/3, 1984, at Bhopal, the Indian Council of Medical Research (ICMR) started following up on four population cohorts with different levels of post-disaster mortality from December 3-6, 1984. Aims: The present study was undertaken to estimate the survival time of the cohort, and investigate the risk of mortality based on exposure, gender, and median age. Settings and Design: Survival analysis is generally used to evaluate factors associated with the time to an event of failure or death among any covered population. Methods and Materials: To know the cause of death and mortality rate, a retrospective cohort analysis was conducted on the outcomes of 92,320 individuals with an exposed and non-exposed group from 1985 to 2015 in Bhopal, India. Statistical Analysis Used: Basic survival analysis method, Kaplan-Meier method, and Cox proportional hazard regression model were used to analyze the mortality risk. Results: During the past 30 years, the survivability was 87.25%, and the mortality rate was 7.2% for the cohort population of Bhopal gas survivors. Cox regression analysis showed that exposed, males, and individuals above 21 years (at the time of the disaster) were at higher risk of mortality from 1985 to 2015. Conclusions: During the initial two phases, the mortality was higher in the exposed group, but over time, their survival turned out to be the same in both groups.

Background & objectives: COVID-19 pandemic has triggered social stigma towards individuals affected and their families. This study describes the process undertaken for the development and validation of scales to assess stigmatizing attitudes and experiences among COVID-19 and non-COVID-19 participants from the community. Methods: COVID-19 Stigma Scale and Community COVID-19 Stigma Scale constituting 13 and six items, respectively, were developed based on review of literature and news reports, expert committee evaluation and participants' interviews through telephone for a multicentric study in India. For content validity, 61 (30 COVID-19-recovered and 31 non-COVID-19 participants from the community) were recruited. Test-retest reliability of the scales was assessed among 99 participants (41 COVID-19 recovered and 58 non-COVID-19). Participants were administered the scale at two-time points after a gap of 7-12 days. Cronbach's alpha, overall percentage agreement and kappa statistics were used to assess internal consistency and test-retest reliability. Results: Items in the scales were relevant and comprehensible. Both the scales had Cronbach's α above 0.6 indicating moderate-to-good internal consistency. Test-retest reliability assessed using kappa statistics indicated that for the COVID-19 Stigma Scale, seven items had a moderate agreement (0.4-0.6). For the Community COVID-19 Stigma Scale, four items had a moderate agreement. Interpretation & conclusions: Validity and reliability of the two stigma scales indicated that the scales were comprehensible and had moderate internal consistency. These scales could be used to assess COVID-19 stigma and help in the development of appropriate stigma reduction interventions for COVID-19 infected, and mitigation of stigmatizing attitudes in the community.
