Cost of acute respiratory illness episode and its determinants among community-dwelling older adults: a four-site cohort study from India.

Introduction: Advocacy for the provision of public health resources, including vaccine for the prevention of acute respiratory illnesses (ARIs) among older adults in India, needs evidence on costs and benefits. Using a cohort of community-dwelling adults aged 60 years and older in India, we estimated the cost of ARI episode and its determinants. Methods: We enrolled 6016 participants in Ballabgarh, Chennai, Kolkata and Pune from July 2018 to March 2020. They were followed up weekly to identify ARI and classified them as acute upper respiratory illness (AURI) or pneumonia based on clinical features based on British Thoracic Society guidelines. All pneumonia and 20% of AURI cases were asked about the cost incurred on medical consultation, investigation, medications, transportation, food and lodging. The cost of services at public facilities was supplemented by WHO-Choosing Interventions that are Cost-Effective(CHOICE) estimates for 2019. Indirect costs incurred by the affected participant and their caregivers were estimated using human capital approach. We used generalised linear model with log link and gamma family to identify the average marginal effect of key determinants of the total cost of ARI. Results: We included 2648 AURI and 1081 pneumonia episodes. Only 47% (range 36%-60%) of the participants with pneumonia sought care. The mean cost of AURI episode was US$13.9, while that of pneumonia episode was US$25.6, with indirect costs comprising three-fourths of the total. The cost was higher among older men by US$3.4 (95% CI: 1.4 to 5.3), those with comorbidities by US$4.3 (95% CI: 2.8 to 5.7) and those who sought care by US$17.2 (95% CI: 15.1 to 19.2) but not by influenza status. The mean per capita annual cost of respiratory illness was US$29.5. Conclusion: Given the high community disease and cost burden of ARI, intensifying public health interventions to prevent and mitigate ARI among this fast-growing older adult population in India is warranted.

Predictors of Out-of-Pocket Expenditure on Health Incurred by Elderly Persons Residing in a Rural Area of Faridabad District.

BACKGROUND: A significant portion of India's 1.2 billion population consists of elderly individuals, accounting for approximately 8.6%, who incur substantial out-of-pocket (OOP) healthcare expenses. Any policy for the elderly should encompass financial protection from illness-related expenditures. However, the lack of comprehensive information on OOP expenditure and its determinants precludes such action. METHODS: We conducted a cross-sectional study of 400 elderly persons residing in the rural town of Ballabgarh. The participants were randomly selected using the health demographic surveillance system. We utilized questionnaires and tools to assess the costs associated with outpatient and inpatient services in the previous year, as well as gather information on socio-demographics (individual characteristics), morbidity (motivation for seeking care), and social engagement (health-seeking). RESULTS: A total of 396 elderly persons participated, with a mean (SD) age of 69.4 (6.7), and 59.4% females. Nearly 96% and 50% of the elderly availed of outpatient and inpatient services, respectively, in the preceding year. The mean (IQR) annual OOP expenditure, as per the consumer price index 2021, was INR 12,543 (IQR, INR 8,288-16,787), with a median of INR 2,860 (IQR, INR 1,458-7,233), explained significantly by sex, morbidity status, social engagement, and mental health. CONCLUSION: In low-middle-income countries like India, policymakers may consider pre-payment mechanisms like health insurance for the elderly, using such prediction scores.

ST elevation myocardial infarction - national trend analysis with mortality differences in outcomes based on day of hospitalization.

BACKGROUND: Patientswho present with acute ST elevation myocardial infarction (STEMI) need emergent revascularization. Our study aims to investigate the outcomes in patients with STEMI admitted during weekends versus weekdays. METHODS: We conducted a retrospective analysis of the nationwide inpatient sample database. Patients with an admitting diagnosis of STEMI identified by the International Classification of Disease code for the year 2016 were analyzed. A weighted descriptive analysis was performed to generate national estimates. Patients admitted over the weekend were compared to those admitted over the weekday. Patients were stratified by demographic and clinical factors including the Elixhauser comorbidity index. The primary outcome was in-hospital mortality and secondary outcomes were percutaneous coronary intervention (PCI) utilization rate, rate of transfer-out, length of stay (LOS), and total hospital charges. Statistical analysis including linear and logistic regression was performed using STATA. RESULTS: A total of 163 715 adult patients were admitted with STEMI, of which 27.9% (45 635) were admitted over the weekend. There were 76.2% Caucasians, 9.3% African Americans, and 8.0% Hispanics. Mean age of the patients was 63.2 years (95% CI, 62.9-63.5) for the weekend group and 63.7 years (95% CI, 63.5-63.9) for weekday admissions. The majority of the patients in both groups had Medicare (43.7% and 45.8% on weekends and weekdays, respectively; P = 0.0047). After adjusting for age, sex, race, income, Elixhauser comorbidity index, PCI use, hospital location, teaching status, and bed size, mortality was not significantly different in weekend versus weekday admissions (odds ratios 1.04; P = 0.498; 95% CI, 0.93-1.16). There was no significant difference in mean total charge per admission during the weekend versus weekday admissions ($107 093 versus $106 869; P = 0.99.) Mean LOS was 4.1 days for both groups (P = 0.81). CONCLUSIONS: There were no significant differences in mortality, LOS, or total hospital charge in STEMI patients being admitted during the weekend versus weekdays.

Assessment of the efficacy of digital panoramic radiographs in analyzing changes in bone mineral density in postmenopausal women.

Introduction: Osteoporosis is described by the World Health Organization (WHO) as a 'progressive systemic skeletal disease characterized by low bone mass, microarchitectural deterioration of bone tissue, a consequent increase in bone fragility, and susceptibility to fracture. The maxilla and mandible are also affected by osteoporotic changes and these may be visualized using an Orthopantomogram. Aims and Objectives: To determine the radiomorphometric indices in the digital orthopantomograms, to determine the bone mineral density (BMD) of the lumbar spine and femur using DXA (Dual-Energy X-ray Absorptiometry) scan, to compare the measured indices between the BMD categories and to assess the correlation of these indices with the measured BMD. Materials and Methods: The study population included 30 postmenopausal female patients. The BMD was measured at the lumbar spine and at the femur and the patients were divided into three groups of 10 subjects based on their BMD status (normal, osteopenia, and osteoporosis). The patients were then subjected to panoramic radiography and four panoramic indices were assessed (simple visual estimation, mandibular cortical index, mental index, and antegonial index). The measured indices were compared between the three BMD categories. The correlation between the indices and the BMD was also observed. Results: The measured indices showed significant difference among the BMD categories. The quantitative indices also demonstrated a positive correlation with the measured BMD of the lumbar spine and the femur. Conclusion: Panoramic radiography may be used as a diagnostic tool for screening and identifying subjects who are likely to have osteoporosis.

Global, regional, and national disease burden estimates of acute lower respiratory infections due to respiratory syncytial virus in children younger than 5 years in 2019: a systematic analysis.

BACKGROUND: Respiratory syncytial virus (RSV) is the most common cause of acute lower respiratory infection in young children. We previously estimated that in 2015, 33·1 million episodes of RSV-associated acute lower respiratory infection occurred in children aged 0-60 months, resulting in a total of 118 200 deaths worldwide. Since then, several community surveillance studies have been done to obtain a more precise estimation of RSV associated community deaths. We aimed to update RSV-associated acute lower respiratory infection morbidity and mortality at global, regional, and national levels in children aged 0-60 months for 2019, with focus on overall mortality and narrower infant age groups that are targeted by RSV prophylactics in development. METHODS: In this systematic analysis, we expanded our global RSV disease burden dataset by obtaining new data from an updated search for papers published between Jan 1, 2017, and Dec 31, 2020, from MEDLINE, Embase, Global Health, CINAHL, Web of Science, LILACS, OpenGrey, CNKI, Wanfang, and ChongqingVIP. We also included unpublished data from RSV GEN collaborators. Eligible studies reported data for children aged 0-60 months with RSV as primary infection with acute lower respiratory infection in community settings, or acute lower respiratory infection necessitating hospital admission; reported data for at least 12 consecutive months, except for in-hospital case fatality ratio (CFR) or for where RSV seasonality is well-defined; and reported incidence rate, hospital admission rate, RSV positive proportion in acute lower respiratory infection hospital admission, or in-hospital CFR. Studies were excluded if case definition was not clearly defined or not consistently applied, RSV infection was not laboratory confirmed or based on serology alone, or if the report included fewer than 50 cases of acute lower respiratory infection. We applied a generalised linear mixed-effects model (GLMM) to estimate RSV-associated acute lower respiratory infection incidence, hospital admission, and in-hospital mortality both globally and regionally (by country development status and by World Bank Income Classification) in 2019. We estimated country-level RSV-associated acute lower respiratory infection incidence through a risk-factor based model. We developed new models (through GLMM) that incorporated the latest RSV community mortality data for estimating overall RSV mortality. This review was registered in PROSPERO (CRD42021252400). FINDINGS: In addition to 317 studies included in our previous review, we identified and included 113 new eligible studies and unpublished data from 51 studies, for a total of 481 studies. We estimated that globally in 2019, there were 33·0 million RSV-associated acute lower respiratory infection episodes (uncertainty range [UR] 25·4-44·6 million), 3·6 million RSV-associated acute lower respiratory infection hospital admissions (2·9-4·6 million), 26 300 RSV-associated acute lower respiratory infection in-hospital deaths (15 100-49 100), and 101 400 RSV-attributable overall deaths (84 500-125 200) in children aged 0-60 months. In infants aged 0-6 months, we estimated that there were 6·6 million RSV-associated acute lower respiratory infection episodes (4·6-9·7 million), 1·4 million RSV-associated acute lower respiratory infection hospital admissions (1·0-2·0 million), 13 300 RSV-associated acute lower respiratory infection in-hospital deaths (6800-28 100), and 45 700 RSV-attributable overall deaths (38 400-55 900). 2·0% of deaths in children aged 0-60 months (UR 1·6-2·4) and 3·6% of deaths in children aged 28 days to 6 months (3·0-4·4) were attributable to RSV. More than 95% of RSV-associated acute lower respiratory infection episodes and more than 97% of RSV-attributable deaths across all age bands were in low-income and middle-income countries (LMICs). INTERPRETATION: RSV contributes substantially to morbidity and mortality burden globally in children aged 0-60 months, especially during the first 6 months of life and in LMICs. We highlight the striking overall mortality burden of RSV disease worldwide, with one in every 50 deaths in children aged 0-60 months and one in every 28 deaths in children aged 28 days to 6 months attributable to RSV. For every RSV-associated acute lower respiratory infection in-hospital death, we estimate approximately three more deaths attributable to RSV in the community. RSV passive immunisation programmes targeting protection during the first 6 months of life could have a substantial effect on reducing RSV disease burden, although more data are needed to understand the implications of the potential age-shifts in peak RSV burden to older age when these are implemented.

Costs of TB care incurred by adult patients with newly diagnosed drug-sensitive TB in Ballabgarh block in northern India.

BACKGROUND: India's National Tuberculosis Elimination Programme (NTEP) provides free diagnosis and treatment services but does not monitor TB-related costs. This study aimed to estimate the direct and indirect costs borne by adult patients with newly diagnosed TB. METHODS: A longitudinal study in Ballabgarh block, Haryana (North India) was conducted. A total of 110 patients were interviewed and data regarding costs were collected at three points of time (after diagnosis, at the end of intensive phase and at the end of the treatment) using a semistructured questionnaire. The total direct (out-of-pocket expenses) and indirect (income lost) costs before and during treatment were calculated for patients who completed the treatment. RESULTS: We enrolled 110 patients with drug-sensitive TB; 6 patients could not complete the treatment. The TB-related median total cost was US$150 (IQR 65-335). The median prediagnosis and postdiagnosis costs were US$42 (IQR 19-313) and US$63 (IQR 10.2-190), respectively. The median direct and indirect costs were US$75 (IQR 36-148) and US$16 (IQR 0-197), respectively. A catastrophic cost was experienced by 18% (95% CI 12 to 27%) of households. CONCLUSION: Despite free diagnosis and treatment services, there is a substantial TB-related cost for TB care under the NTEP. Accelerated efforts are needed to achieve the target of zero catastrophic cost.

Preparedness of primary and secondary health facilities in India to address major noncommunicable diseases: results of a National Noncommunicable Disease Monitoring Survey (NNMS).

BACKGROUND: The monitoring framework for evaluating health system response to noncommunicable diseases (NCDs) include indicators to assess availability of affordable basic technologies and essential medicines to treat them in both public and private primary care facilities. The Government of India launched the National Program for Prevention and Control of Cancer, Diabetes, Cardiovascular diseases and Stroke (NPCDCS) in 2010 to strengthen health systems. We assessed availability of trained human resources, essential medicines and technologies for diabetes, cardiovascular and chronic respiratory diseases as one of the components of the National Noncommunicable Disease Monitoring Survey (NNMS - 2017-18). METHODS: NNMS was a cross-sectional survey. Health facility survey component covered three public [Primary health centre (PHC), Community health centre (CHC) and District hospital (DH)] and one private primary in each of the 600 primary sampling units (PSUs) selected by stratified multistage random sampling to be nationally representative. Survey teams interviewed medical officers, laboratory technicians, and pharmacists using an adapted World Health Organization (WHO) - Service Availability and Readiness Assessment (SARA) tool on handhelds with Open Data Kit (ODK) technology. List of essential medicines and technology was according to WHO - Package of Essential Medicines and Technologies for NCDs (PEN) and NPCDCS guidelines for primary and secondary facilities, respectively. Availability was defined as reported to be generally available within facility premises. RESULTS: Total of 537 public and 512 private primary facilities, 386 CHCs and 334 DHs across India were covered. NPCDCS was being implemented in 72.8% of CHCs and 86.8% of DHs. All essential technologies and medicines available to manage three NCDs in primary care varied between 1.1% (95% CI; 0.3-3.3) in rural public to 9.0% (95% CI; 6.2-13.0) in urban private facilities. In NPCDCS implementing districts, 0.4% of CHCs and 14.5% of the DHs were fully equipped. DHs were well staffed, CHCs had deficits in physiotherapist and specialist positions, whereas PHCs reported shortage of nurse-midwives and health assistants. Training under NPCDCS was uniformly poor across all facilities. CONCLUSION: Both private and public primary care facilities and public secondary facilities are currently not adequately prepared to comprehensively address the burden of NCDs in India.

Burden, Disability and Public Health Importance of Headache Disorders in India.

Headache disorders, characterized by recurrent headache, are among the most common disorders of the nervous system. The aim of this study was to document epidemiological and economic burden due to headache globally and in India and suggest a public health approach to address headache disorders for India. We reviewed the available literature on burden due to headache, its management using a primary health care approach and health system barriers, with special emphasis on India. Globally, it has been estimated that prevalence of current headache disorder (symptomatic within last year) among adults is about 50%, around 30% report migraine and headache on 15 or more days every month affects 1.7-4% people. The Global Burden of Disease Study 2016 estimated that migraine caused 45·1 million (95% UI 29·0-62·8) and tension-type headache 7·2 million (95% UI 4·6-10·5) years of life lived with disability. Limited data available in India support such high burden. These studies also indicate high diagnostic and treatment gaps for headache disorders in India. Major challenges in addressing headache disorders effectively in India are low perceived severity, absence of burden data, lack of standard treatment protocols for headache disorders and primary care models for neurological disorders in developing country context. There needs to be a better appreciation of the burden and a public health approach among all stakeholders, if burden of headache disorders is to be addressed effectively in India.

Global burden of acute lower respiratory infection associated with human metapneumovirus in children under 5 years in 2018: a systematic review and modelling study.

BACKGROUND: Human metapneumovirus is a common virus associated with acute lower respiratory infections (ALRIs) in children. No global burden estimates are available for ALRIs associated with human metapneumovirus in children, and no licensed vaccines or drugs exist for human metapneumovirus infections. We aimed to estimate the age-stratified human metapneumovirus-associated ALRI global incidence, hospital admissions, and mortality burden in children younger than 5 years. METHODS: We estimated the global burden of human metapneumovirus-associated ALRIs in children younger than 5 years from a systematic review of 119 studies published between Jan 1, 2001, and Dec 31, 2019, and a further 40 high quality unpublished studies. We assessed risk of bias using a modified Newcastle-Ottawa Scale. We estimated incidence, hospital admission rates, and in-hospital case-fatality ratios (hCFRs) of human metapneumovirus-associated ALRI using a generalised linear mixed model. We applied incidence and hospital admission rates of human metapneumovirus-associated ALRI to population estimates to yield the morbidity burden estimates by age bands and World Bank income levels. We also estimated human metapneumovirus-associated ALRI in-hospital deaths and overall human metapneumovirus-associated ALRI deaths (both in-hospital and non-hospital deaths). Additionally, we estimated human metapneumovirus-attributable ALRI cases, hospital admissions, and deaths by combining human metapneumovirus-associated burden estimates and attributable fractions of human metapneumovirus in laboratory-confirmed human metapneumovirus cases and deaths. FINDINGS: In 2018, among children younger than 5 years globally, there were an estimated 14·2 million human metapneumovirus-associated ALRI cases (uncertainty range [UR] 10·2 million to 20·1 million), 643 000 human metapneumovirus-associated hospital admissions (UR 425 000 to 977 000), 7700 human metapneumovirus-associated in-hospital deaths (2600 to 48 800), and 16 100 overall (hospital and community) human metapneumovirus-associated ALRI deaths (5700 to 88 000). An estimated 11·1 million ALRI cases (UR 8·0 million to 15·7 million), 502 000 ALRI hospital admissions (UR 332 000 to 762 000), and 11 300 ALRI deaths (4000 to 61 600) could be causally attributed to human metapneumovirus in 2018. Around 58% of the hospital admissions were in infants under 12 months, and 64% of in-hospital deaths occurred in infants younger than 6 months, of which 79% occurred in low-income and lower-middle-income countries. INTERPRETATION: Infants younger than 1 year have disproportionately high risks of severe human metapneumovirus infections across all World Bank income regions and all child mortality settings, similar to respiratory syncytial virus and influenza virus. Infants younger than 6 months in low-income and lower-middle-income countries are at greater risk of death from human metapneumovirus-associated ALRI than older children and those in upper-middle-income and high-income countries. Our mortality estimates demonstrate the importance of intervention strategies for infants across all settings, and warrant continued efforts to improve the outcome of human metapneumovirus-associated ALRI among young infants in low-income and lower-middle-income countries.

Direct and indirect patient costs of tuberculosis care in India.

OBJECTIVE: To synthesise the evidence for estimating the direct and indirect patient costs of drug-sensitive and drug-resistant tuberculosis care in India. METHOD: PubMed, Embase, Web of Science, IndMED and Google Scholar were searched for studies conducted in India between 2000 and 2018 and published in English. The search terms were "tuberculosis" AND "costs" (cost Analysis, economics, cost of illness, health care costs, health expenditures, direct service costs, catastrophic cost) AND "India". The cost of TB care was from the patient's perspective. Data regarding costs were extracted, indexed to the year 2018 using cumulative inflation rate and converted to US dollars at the exchange rate of 2018. RESULTS: Thirteen studies were included in this review. The mean (unweighted) total cost incurred by patients being treated for drug-sensitive TB in a public health facility was $ 235.00 (SD- 222.10), and the median of means was $ 170.60 (range - 43.70-718.40). The mean direct cost was 45.5% of the total cost. Only one study, which was conducted in a private facility, reported the mean total cost for drug-resistant TB as $ 7778.04. Catastrophic cost (total cost ≥ 20% of the total annual household income) was experienced by 7% to 32.4% of drug-sensitive TB patients and by 68% of drug-resistant TB patients. CONCLUSION: Despite free diagnostic and treatment services provided under the Revised National Tuberculosis Control Programme, the patient cost of tuberculosis care is high. Relevant studies vary widely in methodology and cost reporting.

OBJECTIF: Synthétiser les données probantes permettant d'estimer les coûts directs et indirects des soins anti-TB pour les patients avec une TB sensible ou résistante aux médicaments en Inde. MÉTHODE: PubMed, Embase, Web of Science, IndMED et Google Scholar ont été recherchés pour des études menées en Inde entre 2000 et 2018 et publiées en anglais. Les termes de recherche étaient 'tuberculose' ET 'coûts' (analyse des coûts, économie, coût de la maladie, coûts des soins de santé, dépenses de santé, coûts directs des services, coût catastrophique) ET 'Inde'. Le coût des soins anti-TB était du point de vue du patient. Les données concernant les coûts ont été extraites, indexées pour l'année 2018 en utilisant le taux d'inflation cumulé et converties en dollars US au taux de change de 2018. RÉSULTATS: Treize études ont été incluses dans cette revue. Le coût total moyen (non pondéré) encouru par les patients traités pour une TB sensible aux médicaments dans un établissement de santé public était de 235,00 USD (SD-222,10), et la médiane des moyennes était de 170,60 USD (intervalle - 43,70 - 718,40). Le coût direct moyen était de 45,5% du coût total. Une seule étude, qui a été menée dans un établissement privé, a rapporté le coût moyen total pour la TB résistante aux médicaments équivalent à 7.778,04 USD. Des coûts catastrophiques (coût total ≥ 20% du revenu annuel total du ménage ) ont été subis par 7% à 32,4% des patients avec une TB sensible aux médicaments et par 68% des patients avec une TB résistante aux médicaments. CONCLUSION: Malgré les services gratuits de diagnostic et de traitement fournis dans le cadre du Programme National Révisé de Lutte contre la TB, le coût des soins anti-TB pour les patients est élevé. Les études pertinentes varient considérablement dans la méthodologie et la communication des coûts.

Global Disease Burden Estimates of Respiratory Syncytial Virus-Associated Acute Respiratory Infection in Older Adults in 2015: A Systematic Review and Meta-Analysis.

Respiratory syncytial virus-associated acute respiratory infection (RSV-ARI) constitutes a substantial disease burden in older adults aged ≥65 years. We aimed to identify all studies worldwide investigating the disease burden of RSV-ARI in this population. We estimated the community incidence, hospitalization rate, and in-hospital case-fatality ratio (hCFR) of RSV-ARI in older adults, stratified by industrialized and developing regions, using data from a systematic review of studies published between January 1996 and April 2018 and 8 unpublished population-based studies. We applied these rate estimates to population estimates for 2015 to calculate the global and regional burdens in older adults with RSV-ARI in the community and in hospitals for that year. We estimated the number of in-hospital deaths due to RSV-ARI by combining hCFR data with hospital admission estimates from hospital-based studies. In 2015, there were about 1.5 million episodes (95% confidence interval [CI], .3 million-6.9 million) of RSV-ARI in older adults in industrialized countries (data for developing countries were missing), and of these, approximately 14.5% (214 000 episodes; 95% CI, 100 000-459 000) were admitted to hospitals. The global number of hospital admissions for RSV-ARI in older adults was estimated at 336 000 hospitalizations (uncertainty range [UR], 186 000-614 000). We further estimated about 14 000 in-hospital deaths (UR, 5000-50 000) related to RSV-ARI globally. The hospital admission rate and hCFR were higher for those aged ≥65 years than for those aged 50-64 years. The disease burden of RSV-ARI among older adults is substantial, with limited data from developing countries. Appropriate prevention and management strategies are needed to reduce this burden.

Public health leadership in India: Reflections from my journey.

Public Health discipline has evolved and currently focuses on addressing social determinants of health and working multi-sectorally to promote health. Public Health Leadershipis the practice of mobilizing people, organizations, and communities to effectively tackle tough public health challenges. Leadership is a core competency of public health.Leaders are people with Vision, Influence, Values and Passion to achieve personal and organizational mission.Leadership is not a personal trait but is learnable skill. Leadership is a journey where one goes from being a member of a single team to lead health sector in working with other sectors. A leader moves from carrying out assigned tasks at the beginning of journey to providing a vision to motivate others to achieve their life goals. A true leader grooms leaders to establish a legacy of leadership. Ten lessons from my life would be: Believe in yourself; Seize the opportunities; present a vision of future; get out of comfort zone; expand capacity rather than define limits; strengthen communication and people to people skills; build a team; consider everyone as a potential collaborator; focus on deliverables and on relationships. We should start Public Health leadership course and develop core modules for teaching of leadership to post graduates in all medical schools.

Assessment of implementation status of Cigarettes and Other Tobacco Products Act (COTPA) and its awareness among residents in a block of Haryana.

BACKGROUND: Legislative route is one of the known method to control behaviour of population. Cigarette and Other Tobacco Products Act is one of the laws enacted to control the use of tobacco in India lunched in the year 2003. OBJECTIVE: The objective of this study was to find compliance of COTPA among tobacco stores and to find the knowledge of people regarding COTPA. METHODS: All selected communities were studied by community audit. All stores selling tobacco products were assessed for its compliance to COTPA. Thirty participants from selected communities with in the age range of 18- 65 years were selected and interviewed for knowledge regarding COTPA. RESULTS: A total of 218 stores were found to be selling tobacco. None of the stores were fully compliant to all COTPA clauses. Stores in rural areas were found to be more non-complaint than urban areas. 41% of stores were selling tobacco to minors, 10% were within 100 yards of schools.8% of schools have tobacco advertisement on façade and 24% displayed tobacco products openly. Around half of the participants (n-552) had heard about COTPA whereas only 4% were aware of all 4 provisions of COTPA. CONCLUSION: Although more than a decade passed since the law was enacted poor compliance and knowledge was found among participants.

Progress and Remaining Gaps in Estimating the Global Disease Burden of Influenza.

Influenza has long been a global public health priority because of the threat of another global pandemic. Although data are available for the annual burden of seasonal influenza in many developed countries, fewer disease burden data are available for low-income and tropical countries. In recent years, however, the surveillance systems created as part of national pandemic preparedness efforts have produced substantial data on the epidemiology and impact of influenza in countries where data were sparse. These data are leading to greater interest in seasonal influenza, including implementation of vaccination programs. However, a lack of quality data on severe influenza, nonrespiratory outcomes, and high-risk groups, as well as a need for better mathematical models and economic evaluations, are some of the major gaps that remain. These gaps are the focus of multilateral research and surveillance efforts that will strengthen global efforts in influenza control in the future.

Challenges in conducting a community-based influenza vaccine trial in a rural community in northern India.

Evidence on influenza vaccine effectiveness from low and middle countries (LMICs) is limited due to limited institutional capacities; lack of adequate resources; and lack of interest by ministries of health for influenza vaccine introduction. There are concerns that the highest ethical standards will be compromised during trials in LMICs leading to mistrust of clinical trials. These factors pose regulatory and operational challenges to researchers in these countries. We conducted a community-based vaccine trial to assess the efficacy of live attenuated influenza vaccine and inactivated influenza vaccine in rural north India. Key regulatory challenges included obtaining regulatory approvals, reporting of adverse events, and compensating subjects for trial-related injuries; all of which were required to be completed in a timely fashion. Key operational challenges included obtaining audio-visual consent; maintaining a low attrition rate; and administering vaccines during a narrow time period before the influenza season, and under extreme heat. We overcame these challenges through advanced planning, and sustaining community engagement. We adapted the trial procedures to cope with field conditions by conducting mock vaccine camps; and planned for early morning vaccination to mitigate threats to the cold chain. These lessons may help investigators to confront similar challenges in other LMICs.

Estimation of Burden of Influenza among under-Five Children in India: A Meta-Analysis.

BACKGROUND: We estimated the burden of influenza-related acute respiratory tract infection (ARI) among under-fives in India through meta-analysis. METHODOLOGY: We estimated pooled incidence and proportional positivity of laboratory-diagnosed influenza among under-fives using data from observational studies published from 1 January 1961 to 31 December 2016. Death due to influenza was estimated using a multiplier model. RESULTS: Influenza-associated ARI incidence was estimated as 132 per 1000 child-years (115-149). The patients positive for influenza among ARI in outpatients and inpatients were estimated to be 11.2% (8.8-13.6) and 7.1% (5.5-8.8), respectively. We estimated total influenza cases during 2016 as 16 009 207 (13 942 916-18 082 769) in India. Influenza accounted for 10 913 476 (9 504 666-12 362 310) outpatient visits and 109 431 (83 882-134 980) hospitalizations. A total of 27 825 (21 382-34 408) influenza-associated under-five deaths were estimated in India in 2016. CONCLUSION: Influenza imposes a substantial burden among under-fives in India. Public health approach for its prevention and control needs to be explored.

Tongue-driven sonar beam steering by a lingual-echolocating fruit bat.

Animals enhance sensory acquisition from a specific direction by movements of head, ears, or eyes. As active sensing animals, echolocating bats also aim their directional sonar beam to selectively "illuminate" a confined volume of space, facilitating efficient information processing by reducing echo interference and clutter. Such sonar beam control is generally achieved by head movements or shape changes of the sound-emitting mouth or nose. However, lingual-echolocating Egyptian fruit bats, Rousettus aegyptiacus, which produce sound by clicking their tongue, can dramatically change beam direction at very short temporal intervals without visible morphological changes. The mechanism supporting this capability has remained a mystery. Here, we measured signals from free-flying Egyptian fruit bats and discovered a systematic angular sweep of beam focus across increasing frequency. This unusual signal structure has not been observed in other animals and cannot be explained by the conventional and widely-used "piston model" that describes the emission pattern of other bat species. Through modeling, we show that the observed beam features can be captured by an array of tongue-driven sound sources located along the side of the mouth, and that the sonar beam direction can be steered parsimoniously by inducing changes to the pattern of phase differences through moving tongue location. The effects are broadly similar to those found in a phased array-an engineering design widely found in human-made sonar systems that enables beam direction changes without changes in the physical transducer assembly. Our study reveals an intriguing parallel between biology and human engineering in solving problems in fundamentally similar ways.

Cost of Treatment of Febrile Acute Respiratory Infection (FARI) Among Under-Five Children Attending Health Facilities of Ballabgarh, Haryana.

OBJECTIVE: To estimate the expenditure incurred towards treatment of an episode of respiratory infection among under-fives in outpatient and inpatient departments of primary and secondary level health facilities. METHODS: During March 2011 - September 2012, under-five children presenting with febrile acute respiratory infection (FARI) in the outpatient (OPD) and inpatient (IPD) departments of public and private health facilities of Ballabgarh, Haryana were enrolled in the study. Children who were free from co-morbidities and whose contact number or proper address were available, were enrolled and followed up over telephone or by house visits till recovery. Information was collected on expenditure incurred towards treatment of FARI. Work loss of each day was valued as per capita national income per day. Cost of service in public facilities were supplemented by WHO-CHOICE estimates. The cost of respiratory episode in different settings are expressed in median and inter quartile range (IQR). RESULTS: One hundred fourteen children from OPD and 75 from IPD were enrolled and followed up till recovery. Among eligible children 40% and 20% in OPD and IPD were excluded respectively as they could not provide address or contact number. The median costs of an episode treated in OPD and IPD were INR 447(IQR: INR 294-669) and INR 7506.06 (IQR: INR 3765-10,406) respectively. CONCLUSIONS: Respiratory infections are responsible for substantial economic burden, especially with huge proportion of out-of-pocket expenditure. Total cost of a respiratory episode that required hospitalization was 1.5 times the per capita monthly income of an Indian.

Labelling completeness and sodium content of packaged foods in India.

OBJECTIVE: To estimate the proportion of products meeting Indian government labelling regulations and to examine the Na levels in packaged foods sold in India. DESIGN: Nutritional composition data were collected from the labels of all packaged food products sold at Indian supermarkets in between 2012 and 2014. Proportions of products compliant with the Food Safety Standards Authority of India (FSSAI) regulations and labelled with Na content, and mean Na levels were calculated. Comparisons were made against 2010 data from Hyderabad and against the UK Department of Health (DoH) 2017 Na targets. SETTING: Eleven large chain retail stores in Delhi and Hyderabad, India. SUBJECTS: Packaged food products (n 5686) categorised into fourteen food groups, thirty-three food categories and ninety sub-categories. RESULTS: More packaged food products (43 v. 34 %; P<0·001) were compliant with FSSAI regulations but less (32 v. 38 %; P<0·001) reported Na values compared with 2010. Food groups with the highest Na content were sauces and spreads (2217 mg/100 g) and convenience foods (1344 mg/100 g). Mean Na content in 2014 was higher in four food groups compared with 2010 and lower in none (P<0·05). Only 27 % of foods in sub-categories for which there are UK DoH benchmarks had Na levels below the targets. CONCLUSIONS: Compliance with nutrient labelling in India is improving but remains low. Many packaged food products have high levels of Na and there is no evidence that Indian packaged foods are becoming less salty.
