Increased taxes and regulation of Indian cigarillos (bidi) industry: Effects on revenue and years of life lost.

INTRODUCTION: Indian cigarillos (bidi) are low-cost alternatives to cigarettes with only 22% imposed taxes, and turnover of upto INR 4 million per annum exempted from taxation. This paper estimates revenue implications and potential loss of life years (YLLs) averted, if bidi industry is subjected to increased regulations and taxation. METHODS: Revenue estimated at 10% increased regulation and 100% regulation were calculated, followed by estimates at taxes equivalent to cigarettes and World Health Organization - Framework Convention on Tobacco Control (WHO-FCTC) recommendation. Price elasticity was considered to assess demand. Price change in separate fractions (previously regulated and unregulated) were calculated to obtain potential YLLs averted. RESULTS: Current revenue of USD 59.25 million is projected to increase to USD 179.25 million with 695,159 averted YLLs at cigarette equivalent taxes and 10% increased regulation; USD 639.38 million with 4,527,597 averted YLLs with 100% regulation; USD 54.75 million, at WHO recommended taxes with 2,233,740 YLLs averted at 10% increased regulation, and 10,486,192 YLLs at 100% regulation. CONCLUSION: Proposed estimates are inline with WHO recommendations as they consider price elasticity and suggest substantial increase in revenue, while averting YLLs. A national action is needed to drive the policy decisions towards increased regulation and taxation and revision of India's tobacco control legislation. IMPLICATIONS: Our study presented empirical evidence of how the currently underutilized tool of taxation, as proposed in the WHO-FCTC, can be utilized to decrease bidi smoking prevalence and save measurable life years while generating government revenue simultaneously. While the revenue statistics counter the misleading tobacco industry narratives, the projected reduction in mortality will be seen as an irrefutable driving force for policy reforms, targeted at strategic increase in regulation and taxation of the traditional Indian cigarillos industry.

Correlation of severity & clinical outcomes of COVID-19 with virus variants: A prospective, multicentre hospital network study.

BACKGROUND OBJECTIVES: The clinical course of COVID-19 and its prognosis are influenced by both viral and host factors. The objectives of this study were to develop a nationwide platform to investigate the molecular epidemiology of SARS-CoV-2 (Severe acute respiratory syndrome Corona virus 2) and correlate the severity and clinical outcomes of COVID-19 with virus variants. METHODS: A nationwide, longitudinal, prospective cohort study was conducted from September 2021 to December 2022 at 14 hospitals across the country that were linked to a viral sequencing laboratory under the Indian SARS-CoV-2 Genomics Consortium. All participants (18 yr and above) who attended the hospital with a suspicion of SARS-CoV-2 infection and tested positive by the reverse transcription-PCR method were included. The participant population consisted of both hospitalized as well as outpatients. Their clinical course and outcomes were studied prospectively. Nasopharyngeal samples collected were subjected to whole genome sequencing to detect SARS-CoV-2 variants. RESULTS: Of the 4972 participants enrolled, 3397 provided samples for viral sequencing and 2723 samples were successfully sequenced. From this, the evolution of virus variants of concern including Omicron subvariants which emerged over time was observed and the same reported here. The mean age of the study participants was 41 yr and overall 49.3 per cent were female. The common symptoms were fever and cough and 32.5 per cent had comorbidities. Infection with the Delta variant evidently increased the risk of severe COVID-19 (adjusted odds ratio: 2.53, 95% confidence interval: 1.52, 4.2), while Omicron was milder independent of vaccination status. The independent risk factors for mortality were age >65 yr, presence of comorbidities and no vaccination. INTERPRETATION CONCLUSIONS: The authors believe that this is a first-of-its-kind study in the country that provides real-time data of virus evolution from a pan-India network of hospitals closely linked to the genome sequencing laboratories. The severity of COVID-19 could be correlated with virus variants with Omicron being the milder variant.

mHealth based intervention by social care professionals to support family caregivers to persons with dementia living at home in Sweden (Caregiver Connect): a randomized controlled trial.

BACKGROUND: The majority of persons with dementia in Sweden reside in their own homes with support from family members. Approximately, 12% of persons with dementia have immigrant background. Within the next 20 years, the number of persons with dementia who are non-ethnic Swedes is said to double. Family caregivers with immigrant backgrounds are noted to receive less support in the community than ethnic Swedes and rate their health status lower than ethnic Swedish peers. The Swedish National Board of Health and Welfare have highlighted the importance of follow-up support for family caregivers with immigrant backgrounds as there is a recognized gap in research and available information tailored to meet the needs of this group. PURPOSE OF THE STUDY: The purpose of the study is to test effectiveness of an mHealth based intervention through which community social workers can improve caregiving competence of non-European immigrant family caregivers of people with dementia living at home in Sweden. The overarching aim is to reduce caregiver burden and depressive symptoms, and improve quality of life. METHODS: A randomized controlled trial (RCT) including wait list control group will be performed consisting of an intervention group (A, n = 44) and a wait list control group (B, n = 44), totaling a sample size of 88. On completion of the 10-weeks long intervention in the intervention group, the intervention will be delivered to group B. Effect of the intervention will be analyzed between and within groups over time. The content of the educational component of the intervention is inspired by the iSupport manual developed by the World Health Organization. The contents, in the form of a booklet, aims to equip the family caregivers with structured information on understanding dementia as a condition and its management at home, including self-care guidance designed specifically for family caregivers themselves. DISCUSSION: Similar telephone-delivered intervention studies targeted for family caregivers to persons with dementia are ongoing in Malaysia and will start in India using the same booklet adapted to the local context. These studies will provide evidence on the effectiveness of using digital technologies to deliver support to those who may not be reached or adequately served by the traditional healthcare system. TRIAL REGISTRATION: ISRCTN registry, Registration number ISRCTN64235563.

National and regional prevalence of gestational diabetes mellitus in India: a systematic review and Meta-analysis.

BACKGROUND: Gestational diabetes mellitus (GDM) is frequently misdiagnosed during pregnancy. There is an abundance of evidence, but little is known regarding the regional prevalence estimates of GDM in India. This systematic review and meta-analysis aims to provide valuable insights into the national and regional prevalence of GDM among pregnant women in India. METHODS: We conducted an initial article search on PubMed, Scopus, Google Scholar, and ShodhGanga searches to identify quantitative research papers (database inception till 15th June,2022). This review included prevalence studies that estimated the occurrence of GDM across different states in India. RESULTS: Two independent reviewers completed the screening of 2393 articles, resulting in the identification of 110 articles that met the inclusion criteria, which collectively provided 117 prevalence estimates. Using a pooled estimate calculation (with an Inverse square heterogeneity model), the pooled prevalence of GDM in pregnant women was estimated to be 13%, with a 95% confidence interval (CI) ranging from 9 to 16%.. In India, Diabetes in Pregnancy Study of India (DIPSI) was the most common diagnostic criteria used, followed by International Association of Diabetes and Pregnancy Study Groups (IADPSG) and World Health Organization (WHO) 1999. It was observed that the rural population has slightly less prevalence of GDM at 10.0% [6.0-13.0%, I2=96%] when compared to the urban population where the prevalence of GDM was 12.0% [9.0-16.0%, I2 = 99%]. CONCLUSIONS: This review emphasizes the lack of consensus in screening and diagnosing gestational diabetes mellitus (GDM), leading to varied prevalence rates across Indian states. It thoroughly examines the controversies regarding GDM screening by analyzing population characteristics, geographic variations, diagnostic criteria agreement, screening timing, fasting vs. non-fasting approaches, cost-effectiveness, and feasibility, offering valuable recommendations for policy makers. By fostering the implementation of state-wise screening programs, it can contribute to improving maternal and neonatal outcomes and promoting healthier pregnancies across the country.

Challenges and Barriers Faced by People with TB and Healthcare Workers Providing TB Care and Management - A Qualitative Study.

BACKGROUND: In tuberculosis (TB) care and management, there are practical challenges existing at the patient-provider level leading to implementation barriers at the primary care level. OBJECTIVES: The objective of the study is to explore the challenges and barriers faced by people with TB and health-care workers in TB care and management. MATERIALS AND METHODS: This study was done as a part of a community intervention study between November 2021 and December 2022. Twenty interviews were taken with treatment for TB (n = 7) and health-care personnel (n = 13). Health-care personnel include nursing staff, medical officers, laboratory technicians, community health workers, and medical personnel from tertiary care hospital. Participants were recruited across all levels of health-care systems. Interviews were carried out in the Hindi language, audio recorded, and translated to English. Participants were asked about their experiences of challenges and barriers faced during TB care and management. Qualitative data were coded, and thematic analysis was done manually. RESULTS: The challenges and barriers at the level of people with TB were issues with communication between providers and people with TB, out-of-pocket expenditure, poor adherence to medicines, lack of proper diet, gender issues, and stigma. The challenges and barriers at the level of health-care providers were a lack of infrastructure and logistics, lack of awareness, COVID-19-related issues, lack of workforce, and technical issues. CONCLUSION: Communication between providers and people with TB must be improved to improve the drug adherence and satisfaction of the end user. Proper funding must be provided for the TB programs. People with TB must be counseled properly regarding the free health care services available near their homes to prevent out-of-pocket expenditure. These will help in fast-tracking the elimination of TB.

Estimating the weight of consumed tobacco product waste in various Indian states: a novel method to assess the potential burden of tobacco product waste.

INTRODUCTION: The direct morbidity and mortality caused by tobacco are well documented, but such products also contribute to a range of environmental pollutants resulting from tobacco product waste. No previous studies have yet quantified tobacco product waste in a low-income and middle-income country (LMIC). This study estimates the potential annual waste generated due to consumption of smoked and smokeless tobacco products in India and its states. METHODOLOGY: We systematically collected samples of smoked and smokeless tobacco products from 33 districts of 17 Indian states/union territories. Stratified weights of plastic, paper, foil and filter packaging components, and gross empty package weights were recorded. Prevalence of smoking and smokeless tobacco use at national and state-level estimates was derived from the Global Adult Tobacco Survey (2016-2017) to quantify waste potentially generated by tobacco products. RESULTS: We included 222 brands of tobacco products (70 cigarette, 94 bidi and 58 smokeless tobacco brands) in the final analysis. A total of 170 331 (±29 332) tonnes of waste was estimated to be generated annually, out of which 43.2% was plastic, 3.6% was foil and 0.8% was filter. Two-thirds of the overall waste was contributed by smokeless products alone. Maximum waste was generated in Uttar Pradesh (20.9%; 35 723.7±6151.6 tonnes), Maharashtra (8.9%; 15 116.84±2603.12 tonnes) and West Bengal (8.6%; 14 636.32±2520.37 tonnes). CONCLUSION: This study provides first of its kind national-level evidence on the types (plastic, paper, foil and filter) and quantity of waste potentially generated by use of tobacco products in India. Similar studies from other LMICs can serve to raise consciousness about many negative environmental impacts of tobacco products and need for policies to address them.

Determinants of post discharge mortality among hospitalized COVID-19 patients.

Background & objectives: The post-acute effects of COVID-19 are continually being updated. This investigation was conducted to evaluate the determinants of post discharge mortality in hospitalized COVID-19 patients, especially 18-45 yr of age. Methods: A series of three nested case-control analyses was conducted on follow up data collected in the National Clinical Registry for COVID-19 between September 2020 and February 2023 from 31 hospitals. Matching (1:4) was done by the date of hospital admission ±14 days for the following comparisons: (i) case-patients reported as dead vs. controls alive at any contact within one year follow up; (ii) the same in the 18-45 yr age group and (iii) case-patients reported as dead between the first and one year of follow up vs. controls alive at one year post discharge. Results: The one year post discharge mortality was 6.5 per cent (n=942). Age [≤18 yr: adjusted odds ratio (aOR) (95% confidence interval [CI]): 1.7 (1.04, 2.9); 40-59 yr: aOR (95% CI): 2.6 (1.9, 3.6); ≥60 yr: aOR (95% CI): 4.2 (3.1, 5.7)], male gender [aOR (95% CI): 1.3 (1.1, 1.5)], moderate-to-severe COVID-19 [aOR (95% CI): 1.4 (1.2, 1.8)] and comorbidities [aOR (95%CI): 1.8 (1.4, 2.2)] were associated with higher odds of post-discharge one-year mortality, whereas 60 per cent protection was conferred by vaccination before the COVID-19 infection. The history of moderate-to-severe COVID-19 disease [aOR (95% CI): 2.3 (1.4, 3.8)] and any comorbidities [aOR (95% CI): 3 (1.9, 4.8)] were associated with post-discharge mortality in the 18-45-yr age bracket as well. Post COVID condition (PCC) was reported in 17.1 per cent of the participants. Death beyond the first follow up was associated with comorbidities [aOR (95%CI): 9.4 (3.4, 26.1)] and reported PCC [aOR (95% CI): 2.7 (1.2, 6)]. Interpretation & conclusions: Prior vaccination protects against post discharge mortality till one year in hospitalized COVID-19 patients. PCC may have long term deleterious effects, including mortality, for which further research is warranted.

Factors associated with unexplained sudden deaths among adults aged 18-45 years in India - A multicentric matched case-control study.

BACKGROUND OBJECTIVES: In view of anecdotal reports of sudden unexplained deaths in India's apparently healthy young adults, linking to coronavirus disease 2019 (COVID-19) infection or vaccination, we determined the factors associated with such deaths in individuals aged 18-45 years through a multicentric matched case-control study. METHODS: This study was conducted through participation of 47 tertiary care hospitals across India. Cases were apparently healthy individuals aged 18-45 years without any known co-morbidity, who suddenly (<24 h of hospitalization or seen apparently healthy 24 h before death) died of unexplained causes during 1 st October 2021-31 st March 2023. Four controls were included per case matched for age, gender and neighborhood. We interviewed/perused records to collect data on COVID-19 vaccination/infection and post-COVID-19 conditions, family history of sudden death, smoking, recreational drug use, alcohol frequency and binge drinking and vigorous-intensity physical activity two days before death/interviews. We developed regression models considering COVID-19 vaccination ≤42 days before outcome, any vaccine received anytime and vaccine doses to compute an adjusted matched odds ratio (aOR) with 95 per cent confidence interval (CI). RESULTS: Seven hundred twenty nine cases and 2916 controls were included in the analysis. Receipt of at least one dose of COVID-19 vaccine lowered the odds [aOR (95% CI)] for unexplained sudden death [0.58 (0.37, 0.92)], whereas past COVID-19 hospitalization [3.8 (1.36, 10.61)], family history of sudden death [2.53 (1.52, 4.21)], binge drinking 48 h before death/interview [5.29 (2.57, 10.89)], use of recreational drug/substance [2.92 (1.1, 7.71)] and performing vigorous-intensity physical activity 48 h before death/interview [3.7 (1.36, 10.05)] were positively associated. Two doses lowered the odds of unexplained sudden death [0.51 (0.28, 0.91)], whereas single dose did not. INTERPRETATION CONCLUSIONS: COVID-19 vaccination did not increase the risk of unexplained sudden death among young adults in India. Past COVID-19 hospitalization, family history of sudden death and certain lifestyle behaviors increased the likelihood of unexplained sudden death.

Is telemedicine a holy grail in healthcare policy: clinicians' and patients' perspectives from an Apex Institution in Western India.

BACKGROUND: This study aimed to explore the perception of doctors regarding telemedicine consultations and the level of patient satisfaction with the services received through teleconsultations. METHODS: This cross-sectional study was conducted on clinicians who provided teleconsultations and patients who received teleconsultations in an Apex healthcare institution in Western India. Semi-structured interview schedules were used to record the quantitative and qualitative information. Clinicians' perceptions and patients' satisfaction were assessed using two different 5-point Likert scales. Data were analyzed using SPSS v.23 using non-parametric tests (Kruskal Wallis and Mann-Whitney U). RESULTS: A total of 52 clinicians who delivered teleconsultations and 134 patients who received teleconsultations from those doctors were interviewed in this study. For 69% of doctors, telemedicine was feasible to implement, and for the rest, it was challenging. Doctors believe telemedicine is convenient for patients (77%) and prevents the transmission of infection (94.2%). Difficulty in clinical evaluation (73%), communication (55.7%), network connectivity (34%), diagnosis and investigations (32%), and patients' e-illiteracy (32%) were the most common challenges faced by clinicians. Patients' experiences were positive in terms of ease of registration (82.1%), audio quality (100%), freedom to discuss medicine (94.8%), and comprehension of the diagnoses (88.1%). Patients expressed satisfaction with the length of the teleconsultation (81.4%), the advice and care they received (78.4%), and the manner and communication of the clinicians (78.4%). CONCLUSIONS: Though there were some challenges in the implementation of telemedicine, the clinicians perceived it quite helpful. The majority of the patients were satisfied with teleconsultation services. Difficulty in registration, lack of communication, and a deep-rooted mindset of physical consultations were the primary concerns from the patient side.

Musculoskeletal disorders among doctors and nursing officers : an occupational hazard of overstrained healthcare delivery system in western Rajasthan, India.

BACKGROUND: The present study was conducted to estimate the prevalence and distribution of MSDs in different anatomical regions among Doctors and NO and to determine their ergonomic risk factors and predictors. METHODS: This cross-sectional study was conducted in an apex institution in Western India. The socio-demographic information, medical and occupational history, and other personal and work-related attributes were captured using a semi-structured questionnaire, which was developed and finalized by piloting on 32 participants (who were not part of the study). Nordic Musculoskeletal and International Physical Activity Questionnaires were used to assess MSDs and Physical activity. Data were analyzed using SPSS v.23. Prevalence of Musculoskeletal Symptoms (M.S.), Multisite Musculoskeletal Symptoms (MMS), and Widespread Musculoskeletal Symptoms (WMS) were calculated. A comparison was made to estimate the burden and distribution of MSD among Doctors and Nursing officers. Logistic regression was applied to identify the predictors of MSDs and pinpoint the risk factors associated with MSDs. RESULTS: A total of 310 participants, of which 38.7% were doctors, and 61.3% were Nursing Officers (NOs) were included in the study. The mean age of the respondents was 31.63 ± 4.9 years. Almost 73% (95%CI: 67.9-78.1) of participants had MSD in the last 12 months, with approximately 41.6% (95%CI: 36.1-47.3) suffering from MSDs in the previous seven days of the survey. The lower back (49.7%) and the neck (36.5%) were the most affected sites. Working in the same position for a long time (43.5%) and not taking adequate breaks (31.3%) were the highest self-reported risk factors. Females had significantly higher odds of having pain in the upper back [aOR:2.49(1.27-4.85)], neck [aOR:2.15(1.22-3.77)], shoulder [aOR:2.8 (1.54-5.11)], hips [aOR:9.46 (3.95-22.68)] and knee [aOR:3.8(1.99-7.26)]. CONCLUSIONS: Females, who are NOs, work for > 48 h per week, and fall in the obese category were significantly at more risk of developing MSDs. Working in an awkward position, treating an excessive number of patients in a day, working in the same position for a long period, performing repeated tasks, and not having enough rest breaks were significant risk factors for MSDs.

Comparative analysis of discharge and sediment flux from two contiguous glacierized basins of Central Himalaya, India.

In the present study, suspended sediment load (SSL), sediment yield and erosion rates in Pindari Glacier basin (PGB) and Kafni Glacier basin (KGB) have been estimated using daily discharge and suspended sediment concentration (SSC) data for three ablation seasons (2017-2019). For this, one meteorological observatory and two gauging sites have been established at Dwali (confluence point), and water samples have been collected twice in a day for high flow period (July to September) and daily for lean period (May, June and October). An area-velocity method and stage-discharge relationship has been established to convert water level into discharge (m3 s-1). For estimating SSC (mg/l), collected water samples have been filtered, dried, analysed and confirmed with an automatic suspended solid indicator. Further, SSL, sediment yield and erosion rates have been computed using SSC data. The results reveal that mean annual discharge in PGB (35.06 m3 s-1) has been found approximately 1.7 times higher than KGB (20.47 m3 s-1). The average SSC and SSL in PGB have been observed about 396.07 mg/l and 1928.34 tonnes, and in KGB, it is about 359.67 mg/l and 1040.26 tonnes, respectively. The SSC and SSL have followed the pattern of discharge. A significant correlation of SSC and SSL has been found with discharge in both the glacierized basins (p < 0.01). Interestingly, average annual sediment yield in PGB (3196.53 t/km2/yr) and KGB (3087.23 t/km2/yr) have been found almost identical. Likewise, the erosion rates in PGB and KGB have been witnessed about 1.18 and 1.14 mm/yr, respectively. Sediment yield and erosion rates in PGB and KGB have been found in correspondence with other basins of Central Himalaya. These findings will be beneficial for engineers and water resource managers in the management of water resources and hydropower projects in high-altitude areas and in the planning and designing of water structures (dams, reservoirs etc.) in downstream areas.

Is maternal anemia among tribal women being neglected? A study from Southern Rajasthan.

Poor birth outcomes have been linked to maternal anemia. Tribal women are at higher risk of malnutrition and disease due to sociocultural barriers and poor educational status. The data on the prevalence of maternal anemia and its associated factors among pregnant tribal women are limited. A community-based cross-sectional study was conducted among 429 pregnant tribal women for maternal anemia from August 2021 to June 2022. A structured questionnaire was employed to collect sociodemographic data. The prevalence of anemia was 85.7%, with a mean hemoglobin level of 9.21 ± 1.3 g/dL. On applying WHO 2011 anemia criteria for pregnant women, 25.0% had mild anemia, 73.4% had moderate anemia, and 1.6% had severe anemia. The significant factors associated with anemic condition were household condition, monthly income, and husband's occupation. The higher prevalence of anemia among pregnant tribal women is alarming that necessitates a rethinking of health infrastructure and outreach in tribal dominant areas.

Analysis of Predictors and Outcomes of COVID-19 Patients Requiring ICU Admission from COVID-19 Registry, India.

Background: Patients admitted to intensive care units (ICUs) with severe coronavirus disease (COVID-19) are associated with high mortality. The present retrospective, multicenter study describes the predictors and outcomes of COVID-19 patients requiring ICU admission from COVID-19 Registry of Indian Council of Medical Research (ICMR), India. Materials and methods: Prospectively collected data from participating institutions were entered into the electronic National Clinical Registry of COVID-19. We enrolled patients aged >18 years with COVID-19 pneumonia requiring ICU admission between March 2020 and August 2021. Exclusion criteria were negative in RT-PCR report, death within 24 hours of ICU admission, or incomplete data. Their demographic and laboratory variables, ICU severity indices, treatment strategies, and outcomes were analyzed. Results: A total of 5,865 patients were enrolled. Overall mortality was 43.2%. Non-survivors were older (58.2 ± 15.4 vs 53.6 ± 14.7 years; p = 0.001), had multiple comorbidities (33.2% vs 29.5%, p = 0.001), had higher median D-dimer (1.56 vs 1.37, p = 0.015), higher CT severity index (16.8 ± 5.2 vs 13.5 ± 5.47, p = 0.001) and longer median hospital stay (10 vs 8 days, p = 0.001) and ICU stay (5 vs 4 days, p = 0.001), compared with survivors.On multivariate analysis, high CRP (HR 1.008, 95% CI: 1.006-1.010, p = 0.001) and high D-dimer (HR 1.089, 95% CI: 1.065-1.113, p < 0.001) were associated with invasive mechanical ventilation while older age (HR 1.19, CI: 1.001-1.038, p = 0.039) and high D-dimer (HR-1.121, CI: 1.072-1.172, p = 0.001) were independently associated with mortality and while the use of prophylactic low molecular weight heparin (LMWH) (HR 0.647, CI: 0.527-0.794, p = 0.001) lowered mortality. Conclusion: Among 5,865 COVID-19 patients admitted to ICU, mortality was 43.5%. High CRP and D-dimers were independently associated with the need for invasive mechanical ventilation while older age and high D-dimer were associated with higher mortality. The use of prophylactic LMWH independently reduced mortality. How to cite this article: Kajal K, Singla K, Puri GD, Bhalla A, Mukherjee A, Kumar G, et al.

Mapping age- and sex-specific HIV prevalence in adults in sub-Saharan Africa, 2000-2018.

BACKGROUND: Human immunodeficiency virus and acquired immune deficiency syndrome (HIV/AIDS) is still among the leading causes of disease burden and mortality in sub-Saharan Africa (SSA), and the world is not on track to meet targets set for ending the epidemic by the Joint United Nations Programme on HIV/AIDS (UNAIDS) and the United Nations Sustainable Development Goals (SDGs). Precise HIV burden information is critical for effective geographic and epidemiological targeting of prevention and treatment interventions. Age- and sex-specific HIV prevalence estimates are widely available at the national level, and region-wide local estimates were recently published for adults overall. We add further dimensionality to previous analyses by estimating HIV prevalence at local scales, stratified into sex-specific 5-year age groups for adults ages 15-59 years across SSA. METHODS: We analyzed data from 91 seroprevalence surveys and sentinel surveillance among antenatal care clinic (ANC) attendees using model-based geostatistical methods to produce estimates of HIV prevalence across 43 countries in SSA, from years 2000 to 2018, at a 5 × 5-km resolution and presented among second administrative level (typically districts or counties) units. RESULTS: We found substantial variation in HIV prevalence across localities, ages, and sexes that have been masked in earlier analyses. Within-country variation in prevalence in 2018 was a median 3.5 times greater across ages and sexes, compared to for all adults combined. We note large within-district prevalence differences between age groups: for men, 50% of districts displayed at least a 14-fold difference between age groups with the highest and lowest prevalence, and at least a 9-fold difference for women. Prevalence trends also varied over time; between 2000 and 2018, 70% of all districts saw a reduction in prevalence greater than five percentage points in at least one sex and age group. Meanwhile, over 30% of all districts saw at least a five percentage point prevalence increase in one or more sex and age group. CONCLUSIONS: As the HIV epidemic persists and evolves in SSA, geographic and demographic shifts in prevention and treatment efforts are necessary. These estimates offer epidemiologically informative detail to better guide more targeted interventions, vital for combating HIV in SSA.

Recalibrating the Non-Communicable Diseases risk prediction tools for the rural population of Western India.

BACKGROUND: The aim of the present study was to recalibrate the effectiveness of Indian Diabetes Risk Score (IDRS) and Community-Based Assessment Checklist (CBAC) by opportunistic screening of Diabetes Mellitus (DM) and Hypertension (HT) among the people attending health centres, and estimating the risk of fatal and non-fatal Cardio-Vascular Diseases (CVDs) among them using WHO/ISH charts. METHODS: All the people aged ≥ 30 years attending the health centers were screened for DM and HT. Weight, height, waist circumference, and hip circumferences were measured, and BMI and Waist-Hip Ratio (WHR) were calculated. Risk categorization of all participants was done using IDRS, CBAC, and WHO/ISH risk prediction charts. Individuals diagnosed with DM or HT were started on treatment. The data was recorded using Epicollect5 and was analyzed using SPSS v.23 and MedCalc v.19.8. ROC curves were plotted for DM and HT with the IDRS, CBAC score, and anthropometric parameters. Sensitivity (SN), specificity (SP), Positive Predictive Value (PPV), Negative Predictive Value (NPV), Accuracy and Youden's index were calculated for different cut-offs of IDRS and CBAC scores. RESULTS: A total of 942 participants were included for the screening, out of them, 9.2% (95% CI: 7.45-11.31) were diagnosed with DM for the first time. Hypertension was detected among 25.7% (95% CI: 22.9-28.5) of the participants. A total of 447 (47.3%) participants were found with IDRS score ≥ 60, and 276 (29.3%) with CBAC score > 4. As much as 26.1% were at moderate to higher risk (≥ 10%) of developing CVDs. Area Under the Curve (AUC) for IDRS in predicting DM was 0.64 (0.58-0.70), with 67.1% SN and 55.2% SP (Youden's Index 0.22). While the AUC for CBAC was 0.59 (0.53-0.65). For hypertension both the AUCs were 0.66 (0.62-0.71) and 0.63 (0.59-0.67), respectively. CONCLUSIONS: IDRS was found to have the maximum AUC and sensitivity thereby demonstrating its usefulness as compared to other tools for screening of both diabetes and hypertension. It thus has the potential to expose the hidden NCD iceberg. Hence, we propose IDRS as a useful tool in screening of Diabetes and Hypertension in rural India.

Determinants, risk factors and spatial analysis of multi-drug resistant pulmonary tuberculosis in Jodhpur, India.

This study was planned to estimate the proportion of confirmed multi-drug resistance pulmonary tuberculosis (TB) cases out of the presumptive cases referred to DTC (District Tuberculosis Center) Jodhpur for diagnosis; to identify clinical and socio-demographic risk factors associated with the multidrug-resistant pulmonary TB and to assess the spatial distribution to find out clustering and pattern in the distribution of pulmonary TB with the help of Geographic Information System (GIS). In the Jodhpur district, 150 confirmed pulmonary multi-drug resistant tuberculosis (MDR-TB) cases, diagnosed by probe-based molecular drug susceptibility testing method and categorized as MDR in DTC's register (District Tuberculosis Center), were taken. Simultaneously, 300 control of confirmed non-MDR or drug-sensitive pulmonary TB patients were taken. Statistical analysis was done with logistic regression. In addition, for spatial analysis, secondary data from 2013-17 was analyzed using Global Moran's I and Getis and Ordi (Gi*) statistics. In 2012-18, a total of 12563 CBNAAT (Cartridge-based nucleic acid amplification test) were performed. 2898 (23%) showed M. TB positive but rifampicin sensitive, and 590 (4.7%) showed rifampicin resistant. Independent risk factors for MDR TB were ≤60 years age (AOR 3.0, CI 1.3-7.1); male gender (AOR 3.4, CI 1.8-6.7); overcrowding (AOR 1.6, CI 1.0-2.7); using chulha (smoke appliance) for cooking (AOR 2.5, CI 1.2-4.9), past TB treatment (AOR 5.7, CI 2.9-11.3) and past contact with MDR patient (AOR 10.7, CI 3.7-31.2). All four urban TUs (Tuberculosis Units) had the highest proportion of drug-resistant pulmonary TB. There was no statistically significant clustering, and the pattern of cases was primarily random. Most of the hotspots generated were present near the administrative boundaries of TUs, and the new ones mostly appeared in the area near the previous hotspots. A random pattern seen in cluster analysis supports the universal drug testing policy of India. Hotspot analysis helps cross administrative border initiatives with targeted active case finding and proper follow-up.

SARS-CoV-2 IgG Antibody and its Clinical Correlates in Convalescent Plasma Donors: An Indian Experience.

SARS-CoV-2, a novel coronavirus, emerged a year ago in Wuhan, China causing a new pandemic. Convalescent plasma therapy has been applied previously to many infectious diseases and has shown a successful result. This study was planned to assess the Anti-SARS-CoV-2 IgG antibody levels in convalescent COVID-19 patients. In this study, serum samples from 210 persons infected by SARS-CoV-2, treated and discharged from the hospital were collected. Anti-SARS-CoV-2 IgG antibody levels were detected using a chemiluminescence assay. A directory of convalescent plasma donors was created. Anti-SARS-CoV-2 IgG antibody levels vary substantially in the study population with a mean of 51.2 AU/ml. On comparing the serum anti-SARS-CoV-2 IgG antibody levels, a significant difference was observed between the subjects who had cough and those who did not (p = 0.0004). Similar significant findings were found with total protein and globulin levels on comparing the individuals with different antibody status (positive, negative and equivocal). The middle-aged and old age people had high Ab titres compared to younger individuals and the duration of the hospital stay was found to be positively correlated with the anti-SARS-CoV-2 IgG antibody. Cough, age and duration of the hospital stay was found to play a significant role in the development of Anti-SARS-CoV-2 IgG levels. Further, the data suggests that blood groups have a lesser impact on the severity of disease and the development of antibodies. Patients who present with the cough are more likely to develop antibodies.

Intrinsic capacity of rural elderly in thar desert using world health organization integrated care for older persons screening tool: A pilot study.

Integrated Care for Older Persons (ICOPE) screening tool helps to address declines in physical and mental capacities in older people. In India, majority of the older population resides in rural areas and there is a paucity of studies that demonstrates the utility of the ICOPE screening tool in India. Thus, a cross-sectional study was conducted to demonstrate the feasibility of using the World Health Organization ICOPE screening tool in a rural population. Comprehensive geriatric assessment of intrinsic capacity revealed cognitive decline in 31.5% (n = 142) participants, diminished mobility 52.1% (n = 235) participants, eye problems in 49.4% (n = 223) participants, and hearing loss in 68.3% (n = 308) participants. Gender difference was statistically significant with mobility limitation (P = 0.005; χ2 = 7.95) and feeling of pain (P = 0.001; χ2 = 15.64), being more in females than males. This tool seems suitable in identifying the intrinsic capacity of the rural elderly.

COVID-19 vaccine hesitancy among medical students in India.

The coronavirus disease 2019 (COVID-19) vaccine was launched in India on 16 January 2021, prioritising health care workers which included medical students. We aimed to assess vaccine hesitancy and factors related to it among medical students in India. An online questionnaire was filled by 1068 medical students across 22 states and union territories of India from 2 February to 7 March 2021. Vaccine hesitancy was found among 10.6%. Concern regarding vaccine safety and efficacy, lack of awareness regarding their eligibility for vaccination and lack of trust in government agencies predicted COVID-19 vaccine hesitancy among medical students. On the other hand, the presence of risk perception regarding themselves being affected with COVID-19 reduced vaccine hesitancy as well as hesitancy in participating in COVID-19 vaccine trials. Vaccine-hesitant students were more likely to derive information from social media and less likely from teachers at their medical colleges. Choosing between the two available vaccines (Covishield and Covaxin) was considered important by medical students both for themselves and for their future patients. Covishield was preferred to Covaxin by students. Majority of those willing to take the COVID-19 vaccine felt that it was important for them to resume their clinical posting, face-to-face classes and get their personal life back on track. Around three-fourths medical students viewed that COVID-19 vaccine should be made mandatory for both health care workers and international travellers. Prior adult vaccination did not have an effect on COVID-19 vaccine hesitancy. Targeted awareness campaigns, regulatory oversight of vaccine trials and public release of safety and efficacy data and trust building activities could further reduce COVID-19 vaccine hesitancy among medical students.

Transcriptome characterization and generation of marker resource for Himalayan vulnerable species, Ulmus wallichiana.

Ulmus wallichiana is a traditional medicinal plant listed as a vulnerable in the IUCN red list data. Genomic and transcriptomic resources for this species are lacking, hindering its genetic exploration. Further, no polymorphic marker resource is available for this species, thus limiting the elucidation of its underlying genetic diversity, which is a pre-requisite for its conservation. This study was therefore aimed to generate a functionally annotated transcriptomic resource and screen it for SSR regions. We used paired-end Illumina based RNAseq technology and trinity based de novo assembly approach to generate full length transcripts, which were screened for SSR regions and functionally annotated. Around 6.6 million raw reads were de novo assembled transcripts, which were clustered into 146,083 unigenes. 19,909 transcripts were provided with 3986 unique KEGG ids, 70,519 transcripts with 6621 unique Pfam domains, and 45,125 transcripts with 7302 unique INTERPRO domains. 1456 transcripts were identified as transcriptions factors (TFs). Further, 8868 unique GO terms were obtained for the unigenes. The transcripts mapped to 23,056 known pre-determined orthology clusters in the eggNOG database. A total of 16,570 SSRs were identified from the unigenes. Out of the 90 SSRs selected for characterization on 20 genotypes, 28 were polymorphic. Mean effective alleles (Ne) of 2.53, mean observed heterozygosity (Ho) of 0.77, and average polymorphic information content (PIC) of 0.57 were found. This study may facilitate the genetic exploration of this species. The polymorphic SSRs would prove useful to explore its genetic diversity patterns, required for its conservation.
