Validation of the Indian (Hindi) version of the life-space assessment scale among community-dwelling older adults: a multicentric cross-sectional study.

BACKGROUND: The Life-Space Assessment (LSA) is an instrument that measures mobility in older adults as they reach different areas, defined as life-spaces extending from home to beyond towns or regions. The purpose of the study was to develop the Hindi version of the LSA (LSA- H) and to investigate the validity and reliability of the Hindi version as well as its cultural adaptation. METHODS: A cross-sectional study of two hundred forty-five older adults participated in the study from four different study practice areas. Following forward backwards translation, the LSA-H was developed, and the scores were correlated with those of the Activities-Specific Balance Confidence Scale Hindi (ABC- H), the Physical Health Subscale of the WHO-BREF Questionnaire and the Geriatric Depression Scale: Short Form Hindi (GDS-SFH) to test the criterion and concurrent validity. RESULTS: The mean score and standard deviation of the LSA-H questionnaire were 56.53 ± 35.99, those of the Physical Health Subscale of the WHO-BREF instrument were 18.54 ± 7.87, those of the GDS-SFH questionnaire were 6.95 ± 4.21 and those of the ABC- H questionnaire were 54.40 ± 28.96. The Pearson correlation coefficient (r) between the LSA-H score and ABC-H score was 0.707 (p value < 0.0001), that between the LSA-H score and the Physical Health Subscale of the WHO-BREF was 0.766 (p value < 0.0001), and that between the LSA-H score and GDS-SFG score was - 0.674 (p value < 0.0001). CONCLUSION: This study demonstrated that the Hindi version of the LSA is a valid and reliable instrument for assessing living space among older adults in the Hindi language in an Indian population. Furthermore, the LSA-H was significantly correlated with other health assessment tools in terms of functional mobility, general health status and mental well-being.

Sleep Patterns, Issues, Reasons for Sleep Problems, and Their Impact on Academic Performance among First-Year Medical Students in Central India.

Introduction:Sleep is an essential part of the human daily routine. Studies have shown that sleep deprivation causes and worsens a wide range of psychological problems in people of all ages. Undergraduate students' sleep disorders are likely to persist and worsen over time. Medical students who work with sick patients on a daily basis and perform skilled activities find that sleep is very important for them. Aims and objectives: The main objective of the present study was to determine undergraduate medical students' sleeping habits as well as the numerous causes of sleep disorders. The secondary aim of our research was to determine the influence of sleep-related problems on students' academic performance. Methods:Following approval from the Ethics Committee, a cross-sectional study of 171 first-year medical students was conducted using a semi-structured self-administered questionnaire. Data was collected using Google Forms on the internet. Microsoft Excel 2019 was used to enter and analyze data. Prevalence was expressed as percentage with a 95% confidence interval. The mean and standard deviation of continuous variables was reported. Results:Of all included students, 39.2% reported they had six to seven hours of sleep each day. Study-related reasons were indicated by 32.6% of students, followed by those who utilized social media (21.7%). Laziness, exhaustion, annoyance, and restlessness were the top reasons for sleeping less (27.5%). Prior academic success was significantly connected to sleep length, while current sleep duration was not.

Prevalence of presbyopia, spectacles coverage and barriers for unmet need among adult population of rural Jhajjar, Haryana.

Background: Presbyopia is a major cause for near visual impairment among adults. Presbyopia induced visual impairment can be corrected easily by spectacles. We aimed to study the prevalence of presbyopia among adults aged ≥35 years and spectacles coverage among them. We also studied the unmet need for presbyopia along with the barriers to uptake of services. Methods: This is a population-based cross-sectional study conducted among adults aged ≥35 years in a rural district of Haryana. Near vision assessment and semistructured interview schedule were administered by a team of trained ophthalmic assistant, social worker and health assistant. Results: A total of 3832 adults aged ≥35 years were enumerated, from which 3246 (84.7%) were examined. Prevalence of presbyopia was found to be 42.9% (95% confidence interval 41.2-44.6). Participants with increasing age, literacy and women had higher prevalence, and those that were employed and belonged to below poverty line economic status had lower prevalence of presbyopia. Spectacles coverage among presbyopes was found to be 25.8%. There was an inverse association between unmet need for presbyopia and women, increasing education status and office work. Lack of felt need and personal reasons were the most common barriers for unmet need due to presbyopia. Conclusions: There is high prevalence of presbyopia among adult population, with spectacles coverage being low. Awareness activities along with affordable, accessible and socially acceptable services for those affected with presbyopia would be one of the key components of management.

Effectiveness of Visual Inspection with Acetic Acid (VIA) Screening on Cervical Cancer Mortality and Incidence - A Systematic Review and Meta-Analysis.

OBJECTIVES: Despite being a cheap, easy, and commonly used technique for screening early development of cervical cancer, collective evidence on the effect of visual inspection with acetic acid (VIA) for reducing cervical cancer mortality and incidence are conflicting. We conducted a systematic review and meta-analysis to determine the effectiveness of VIA screening on cervical cancer mortality and incidence. METHODS: We searched PubMed, Embase, Cochrane library (Cochrane Database of Systematic Reviews & Cochrane Central Register of Controlled Trials), World Health Organization's (WHO) International Clinical Trials Registry Platform, and Google Scholar to identify studies conducted among women with no history of cervical cancer that assessed effectiveness of VIA on the cervical cancer mortality and incidence. Random effects model was used to estimate incident rate ratio and sensitivity analysis was conducted using Bayesian methods. RESULTS: Of the included 4 studies, three were cluster randomized trials from India and one was quasi-experimental study done in Thailand. Duration of follow-up ranged from 7 to 12 years. Based on 3 trials, pooled rate-ratio for cervical cancer mortality and all-cause mortality was 0.68 (95% CI: 0.56-0.81, I2=0%) and 0.91 (0.85-0.97, I2=57%), respectively. Pooled rate-ratio of invasive cervical cancer was 0.94 (95% CI: 0.67 - 1.30, I2=84%). Likewise, there was non-significant reduction in incidence of stage IB, >=stage II, and unknown stage cervical cancer. CONCLUSIONS: VIA screening may lead to reduction in cervical cancer and all-cause mortality in long run. However, the effectiveness of VIA in preventing invasive cervical cancer is inconclusive.

Frailty, Disability, and Mortality in a Rural Community-Dwelling Elderly Cohort from Northern India.

INTRODUCTION: With increasing proportion of the elderly in the world, detecting and preventing frailty assumes importance to improve the quality of life and health. The study aimed to estimate the prevalence of frailty, disability and its determinants and their relation with mortality among community dwelling elderly cohort. MATERIALS AND METHODS: The study was conducted in a cohort in rural Haryana, India, and was followed till October 2018. Frailty was assessed using the Edmonton Frailty Scale and disability was assessed using the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) scale by trained physicians. RESULTS: The prevalence of frailty was found to be 47.3% (95% confidence interval [CI]: 44.0-50.8). The median WHODAS-2 score was found to be 10.4 (2.1-29.2). Those who were older (odds ratio [OR] - 2.5; 95% CI: 1.8-3.4), women (OR - 3.3; 95% CI: 2.2-4.9) and those with chronic disease (OR 2.3; 95% CI: 1.7-3.1) had higher rates of frailty. The adjusted hazard ratio of death among frail people was 4.7 (2.3-9.7). CONCLUSION: In this study we found the frailty is associated with the mortality among community dwelling elderly. Thus early identification of the frailty and its determinants may help us to reduce the mortality related to this.

COVID-19 pandemic in India: A Comparison of pandemic pattern in Selected States.

The COVID-19 pandemic currently expanded its roots to the 206 countries in the world. The morbidity and mortality are not only threat to humans but also its impact on economy is indirectly affecting us. The current review was done to find trend in various states of India. Data was collected from Ministry of Health and Family Welfare and descriptive analysis of the distribution of COVID-19 cases in different states of India. First case of COVID-19 was diagnosed in southernmost state Kerala and after that it has spread to all other states, but situations are more worsen in states with high international migration. Maharashtra is now the most affected state followed by Delhi. Among epidemic curve of all these states, Maharashtra has rapidly growing epidemic curve with highest slope, whereas Kerala has the lowest. When we compared the day wise cumulative case fatality rate, it was found that the case fatality rate of the states like Maharashtra, Madhya Pradesh & Rajasthan showed decrease in the case fatality rate over the period. Population density is also one of the key determinants of social interaction and thus the spread of disease specifically in communicable diseases. Government of India had taken many strong initiatives e.g. 40 days nation-wide lockdown, thermal screening at airport, announcement of relief packages for poor and quarantine of outsiders but still there are many missed opportunities like, early stoppage of international traffic, compulsory quarantine for all international travellers, better contact tracing, strong law and order and better preparedness plan.

Prevalence and patterns of drug resistant pulmonary tuberculosis in India-A systematic review and meta-analysis.

OBJECTIVE: Drug-resistant tuberculosis (DR-TB) is a major global public health threat. India, as it shares a large fraction of the world's TB burden, is currently at a critical phase due to the rise of drug resistance. Monitoring the prevalence and patterns of drug resistance is essential to measure the progress of TB control programmes. We aimed to systematically review Indian studies on the prevalence and patterns of DR-TB among various treatment types and risk groups. METHODS: A systematic search was conducted on PubMed, Google Scholar, IndMed, major TB journals and other databases for English language articles published till March 2018 that estimated the prevalence of DR TB in new, previously treated, presumptive multidrug resistance (MDR), paediatric and HIV co-infected pulmonary TB patients. Two authors independently conducted the search, assessed study quality, and extracted the relevant data. Pooled prevalence of DR-TB and its types were calculated by DerSimonian-Laird random effects meta-analysis. Heterogeneity was investigated by sub-group and sensitivity analyses. RESULTS: Ninety non-duplicate studies were included. The prevalence of MDR, any drug resistance and extensive drug resistance was 3.5%, 24.9% and 0.06% (among new) and 26.7%, 58.4% and 1.3% (among previously treated), respectively. MDR prevalence among presumptive MDR, paediatric and HIV co-infected TB patients was 23.3%, 5.1% and 18.8%, respectively. MDR prevalence among new TB patients was highest in Maharashtra and lowest in Telangana. There was high heterogeneity between the studies. Study period, place of study and zone were significantly associated with MDR prevalence. CONCLUSIONS: India suffers from a significant burden of DR-TB. Its patterns and prevalence are very heterogeneous across time, region and setting. Implementation of universal drug susceptibility testing in all districts and continuous DR-TB surveillance is crucial to ensure programmatic success.

Public health response to COVID-19 in selected countries - Hits and misses.

BACKGROUND: Lack of a cure or vaccine of COVID-19 forced us to rely on public health interventions (PHIs) for combating the pandemic. The main objective of the study to assess the PHI in selected countries and relate the various factors related to the intervention with the case load of the country. METHODS: An ecological analysis was conducted using secondary data on PHIs and disease burden extracted from official documents and press releases of the respective countries. Disease transmission was described based on calculated doubling time. PHIs were classified into 14 categories within three domains. An intervention score was calculated to reflect the number and stringency of the PHIs. Correlations between intervention scores, daily new cases and doubling time were presented. RESULTS: Brazil and the USA had the lowest intervention scores while South Korea had the highest scores. The median doubling time was negatively correlated with the rapidity of the escalation of the PHIs. CONCLUSION: Dynamic government policies and timely PHIs, which are locally relevant and ably supported by the public are key to successful containment of the COVID-19 pandemic.

Review of Lot Quality Assurance Sampling, Methodology and its Application in Public Health.

Rapid collection of data is of utmost importance in monitoring and evaluation of activities of public health importance. Among others techniques, 30 by 7 cluster sampling and Lot quality assurance sampling(LQAS) methods have been described in literature for this purpose. However, LQAS is often sparingly used in most settings, undermining its importance as a effective epidemiological tool in public health practice. To some extent LQAS is inadequately understood and even less emphasized method, especially in the postgraduate teaching and training. In this paper we aim to explain the use, method and application of LQAS in public health settings as well as discuss common pitfalls to avoid while planning and drawing inferences based on data collected through LQAS.
