RESUMO
INTRODUCTION: The population of men who have sex with men (MSM) in India is vulnerable to HIV/AIDS. India instituted a targeted intervention (TI) programme to reduce this vulnerability. We aimed to measure the assessment of the TI programme for MSM. MATERIALS AND METHODS: The national Integrated Biological and Behavioural Survey (IBBS) was carried out in 2014-2015. We analysed MSM data from the IBBS and used bivariate and multivariate logistic regression to calculate the unadjusted and adjusted odds ratios with 95% confidence intervals. The use of a condom during their last sexual intercourse and consistent condom use during the previous month were considered indicators of programme effectiveness. The propensity score matching method was used to assess the effectiveness of the TI programme. RESULTS: The matched-samples estimate (i.e., average treatment effect on treated) for the use of condoms during their last sexual intercourse increased by 10.0% (0.10; 95% confidence interval [CI] 0.08-0.12), and consistent condom use during the previous month increased by 9.0% (0.09; 95% CI 0.07-0.10) among those who had received condoms from the peer educator/outreach worker compared with those who had not received condoms. CONCLUSIONS: The TI programme intervention among MSM was effective in reducing HIV risk behaviours, as evidenced by an increase in the use of condoms during their last sexual intercourse and consistent condom use during the last month.
RESUMO
With increasing importance being given to preexposure prophylaxis (PrEP) for human immunodeficiency virus prevention among men who have sex with men (MSM) and transgender persons (TG), we undertook a systematic review and meta-analysis of PrEP awareness and acceptability among these key populations in India, and their sociodemographic and behavioral determinants. The systematic review was registered with PROSPERO (CRD42023390508). Studies were included if they provided quantitative data on PrEP awareness or acceptability among MSM or TG in India. MEDLINE, Scopus, Web of Science, and Embase were searched from inception to February 29, 2024, using keywords and database-specific terms. Relevant websites were also searched. Critical appraisal was done using the Joanna Briggs Institute Checklist for Prevalence Studies. Random-effects meta-analysis was done for common outcomes reported by the studies. Reporting was as per the Preferred Reporting Items for Systematic Reviews and Meta-analyses 2020 statement. Ten studies providing cross-sectional data, mostly from South West India, were included for qualitative synthesis. All were conducted in settings where PrEP was not available. The pooled prevalence among MSM and TG was 18.7% (95% confidence interval [CI] 8.7%, 28.7%) for awareness and 79.8% (95% CI 57.4%, 100.0%) for willingness to use daily oral PrEP. This review highlights the felt need for PrEP among MSM and TG in India. Further research is needed to understand user attitudes in different parts of the country.

Background: High HIV prevalence among injecting drug users (IDUs) remains a cause of concern and are considered key drivers of concentrated epidemic in India. The present paper aims to assess the effectiveness of the targeted intervention (TI) program on the risk behaviors among IDUs across regions of India. Materials and Methods: This paper used the data from the integrated biological and behavioral surveillance 2014-2015 among the IDUs in India. Descriptive statistics and propensity score matching analysis was carried out to understand the effectiveness of the TI program on the new needle/syringe used and needle/syringe shared in the last injecting episode by accounting for the covariates. Results: The matched samples estimate, i.e., average treatment effect on treated of new needles/syringe used and shared in the last injecting episode by those who received needles/syringes from peer educator or outreach workers (PE/ORWs) and those who did not receive was 2.8% (confidence interval [CI]: 0.05-5.6) increase in the use of new needles/syringes and 6.5% (CI: -9.7--3.3) decrease in the needles/syringes shared in last injecting episode indicating that IDUs who received new needles/syringes from PE/ORWs are more likely to use new needle/syringe and less likely to share needle/syringes to those who did not receive needles/syringes. The results vary across the different regions of India. Conclusion: TI program proves to be an effective initiative in the behavior change among IDUs as substantiated by use of new needles/syringes and decreased sharing of needles/syringes. TI program coverage varies from region to region and may further be expanded to accelerate the program services to prevent HIV/AIDS.

BACKGROUND: We report the clinical efficacy against COVID-19 infection of BBV152, a whole virion inactivated SARS-CoV-2 vaccine formulated with a toll-like receptor 7/8 agonist molecule adsorbed to alum (Algel-IMDG) in Indian adults. METHODS: We did a randomised, double-blind, placebo-controlled, multicentre, phase 3 clinical trial in 25 Indian hospitals or medical clinics to evaluate the efficacy, safety, and immunological lot consistency of BBV152. Adults (age ≥18 years) who were healthy or had stable chronic medical conditions (not an immunocompromising condition or requiring treatment with immunosuppressive therapy) were randomised 1:1 with a computer-generated randomisation scheme (stratified for the presence or absence of chronic conditions) to receive two intramuscular doses of vaccine or placebo administered 4 weeks apart. Participants, investigators, study coordinators, study-related personnel, the sponsor, and nurses who administered the vaccines were masked to treatment group allocation; an unmasked contract research organisation and a masked expert adjudication panel assessed outcomes. The primary outcome was the efficacy of the BBV152 vaccine in preventing a first occurrence of laboratory-confirmed (RT-PCR-positive) symptomatic COVID-19 (any severity), occurring at least 14 days after the second dose in the per-protocol population. We also assessed safety and reactogenicity throughout the duration of the study in all participants who had received at least one dose of vaccine or placebo. This report contains interim results (data cutoff May 17, 2021) regarding immunogenicity and safety outcomes (captured on days 0 to 56) and efficacy results with a median of 99 days for the study population. The trial was registered on the Indian Clinical Trials Registry India, CTRI/2020/11/028976, and ClinicalTrials.gov, NCT04641481 (active, not recruiting). FINDINGS: Between Nov 16, 2020, and Jan 7, 2021, we recruited 25â798 participants who were randomly assigned to receive BBV152 or placebo; 24â419 received two doses of BBV152 (n=12â221) or placebo (n=12â198). Efficacy analysis was dependent on having 130 cases of symptomatic COVID-19, which occurred when 16 973 initially seronegative participants had at least 14 days follow-up after the second dose. 24 (0·3%) cases occurred among 8471 vaccine recipients and 106 (1·2%) among 8502 placebo recipients, giving an overall estimated vaccine efficacy of 77·8% (95% CI 65·2-86·4). In the safety population (n=25â753), 5959 adverse events occurred in 3194 participants. BBV152 was well tolerated; the same proportion of participants reported adverse events in the vaccine group (1597 [12·4%] of 12â879) and placebo group (1597 [12·4%] of 12â874), with no clinically significant differences in the distributions of solicited, unsolicited, or serious adverse events between the groups, and no cases of anaphylaxis or vaccine-related deaths. INTERPRETATION: BBV152 was highly efficacious against laboratory-confirmed symptomatic COVID-19 disease in adults. Vaccination was well tolerated with no safety concerns raised in this interim analysis. FUNDING: Bharat Biotech International and Indian Council of Medical Research.

BACKGROUND: Several methodological tests are available to detect SARS-CoV-2 antibody. Tests are mostly used in the aid of diagnosis or for serological assessment. No tests are fully confirmatory and have variable level of diagnostic ability. We aimed at assessing agreement with three serological tests: quantitative anti receptor binding domain ELISA (Q-RBD), qualitative ELISA (WANTAI SARS-CoV-2 Ab) and qualitative chemiluminescence assay (CLIA). METHODS: This study was a part of a large population based sero-epidemiological cohort study. Participants aged 1 year or older were included from 25 randomly selected clusters each in Delhi urban (urban resettlement colony of South Delhi district) and Delhi rural (villages in Faridabad district, Haryana). Three type of tests were applied to all the baseline blood samples. Result of the three tests were evaluated by estimating the total agreement and kappa value. RESULTS: Total 3491 blood samples collected from March to September, 2021, out of which 1700 (48.7%) from urban and 1791 (51.3%) from rural. Overall 44.1% of participants were male. The proportion of sero-positivity were 78.1%, 75.2% and 31.8% by Wantai, QRBD and CLIA tests respectively. The total agreement between Wantai and QRBD was 94.5%, 53.1% between Wantai and CLIA, and 56.8% between QRBD and CLIA. The kappa value between these three tests were 0.84 (95% CI 0.80-0.87), 0.22 (95% CI 0.19-0.24) and 0.26 (95% CI 0.23-0.28). CONCLUSIONS: There was strong concordance between Wantai and QRBD test. Agreement between CLIA with other two tests was low. Wantai and QRBD tests measuring the antibody to same S protein can be used with high agreement based on the relevant scenario.

Background & objectives: The overall adult prevalence of HIV in India was estimated to be 0.22 per cent in 2019. The HIV prevalence among men who have sex with men (MSM), a high-risk group for HIV, was estimated to be 4.3 per cent, which is 16 times higher than the national average. In Delhi, the estimated prevalence among MSM was 1.8 per cent. Despite free HIV testing services being made available by the National AIDS Control Programme for more than two decades, many MSM were not aware about their HIV status. Therefore, newer testing strategies are needed. Oral HIV self-testing (HIVST) has proved to be one such promising innovation. At present, there are no programme guidelines on HIVST and oral HIVST kit is not available in India. The aim of this study was to understand the perceived advantages and disadvantages of introduction of oral HIVST strategy among MSM. Methods: MSM who were registered with the selected non-governmental organizations working as targeted intervention sites in Delhi, India, were recruited for focus group discussions (FGDs) between January and May 2021. For the purpose of this study, MSM were defined as males who had anal/oral sex with male/hijra partner in the past one month. A total of six FGDs were conducted using a prepared FGD guide. The FGD guide included questions on problems faced during conventional HIV testing, participants' awareness, acceptability and perceptions of oral HIVST. The data were manually coded and entered in NVivo release 1.5 and themes were identified. Results: A total of 67 respondents participated in the FGDs. A total of 28.4 per cent MSM were beggars at traffic lights, 12 per cent were sex workers and 11.9 per cent were bar/event dancers. Nearly half (50.7%) of the participants had undergone HIV testing less than twice in the preceding one year. None of the MSM were aware about oral HIVST. Perceived advantages of oral HIVST were ease of use, confidentiality and the non-invasive pain-free procedure. Perceived concerns included lack of post-test counselling, linkage to care, poor mental health outcomes and forced testing. Interpretation & conclusions: Most MSM had positive perceptions about oral HIVST. Therefore, it is likely that the introduction of oral HIVST may result in higher uptake of HIV testing among MSM.

Background & objectives: HIV sentinel surveillance (HSS) among antenatal women in India has been used to track the epidemic for many years. However, reliable tracking at the local level is not possible as ANC sentinel sites are limited in number and cover a smaller sample size at each site. Prevention of parent-to-child-transmission (PPTCT) programme data has a potential advantage due to better geographical coverage, which could provide more precise HIV case estimates; therefore, we compared HSS ANC data with PPTCT programme data for HIV tracking. Methods: Out of the 499 surveillance sites, where HSS and PPTCT programme was being conducted in 2015, 210 sites (140 urban and 70 rural) were selected using a stratified random sampling method. HSS (n=72,981) and PPTCT (n=112,832) data records were linked confidentially. The sociodemographic characteristics of HSS and PPTCT attendees were compared. HIV prevalence from HSS ANC was compared with the PPTCT programme data using Chi-square test. State- and site-level correlation of HIV prevalence was also done. Concordance between HSS and PPTCT HIV positivity was estimated using kappa statistics. Results: The age distribution of HSS and PPTCT attendees was similar (range: 23 to 27 yr); however, HSS ANC participants were better educated, whereas PPTCT recorded a higher proportion of homemakers. The correlation of HIV prevalence between HSS and PPTCT was high (r=0.9) at the State level and moderate at the site level (r=0.7). The HIV positivity agreement between HSS ANC and PPTCT was good (kappa=0.633). A similar prevalence was reported across 26 States, whereas PPTCT had a significantly lower prevalence than HSS in three States where PPTCT coverage was low. Overall HIV prevalence was 0.31 per cent in HSS and 0.22 per cent in PPTCT (P<0.001). Interpretation & conclusions: High-quality PPTCT programme data can provide reliable HIV trends in India. An operational framework for PPTCT-based surveillance should be pilot-tested in a phased manner before replacing HSS with PPTCT.

Objectives: This study was aimed to estimate the need for palliative care in an urban resettlement colony of Dakshinpuri Extension, New Delhi. Material and Methods: This was a community-based cross-sectional study conducted in New Delhi. We trained four multipurpose workers to screen the households during their routine household-to-household visits. The screening for the need for palliative care was done using three questions - that is, (1) presence of a bedridden patient or (2) person in need for help in activities of daily living or (3) not able to go for work due to any physical chronic illness. If the answer to any of the three screening questions was yes for any member in a household, then these households were visited by a community physician trained in palliative care and a medical social service officer to confirm the need for palliative care. Patients were administered a semi-structured questionnaire containing the sociodemographic details and an assessment of disease status and review of health records was done. The patient and his/her caregiver were also assessed for awareness regarding palliative care. Results: A total of 2028 households were screened and the need for palliative care was found to be 1.5/1000 population (95% CI: 0.9-2.1). The mean age (SD) of patients who need palliative care was 60 years (SD-12.9). The common diseases which required palliative care were stroke with a focal neurological deficit (45.8%), osteoarthritis with marked dependence (20.8%) and cancer (12.5%). None of the patients was receiving palliative care as patients and their caregivers were not aware of the term palliative care/end of life care/home care for bedridden people/community-based care. Conclusion: The need for palliative care in an urban resettlement colony of North India was found to be 1.1/1000 population. Further studies are required to estimate the need for palliative care in North India.
RESUMO
Background & objectives: The National AIDS Control Organisation (NACO) and the ICMR-National Institute of Medical Statistics, the nodal agency for conducting HIV estimations in India, have been generating HIV estimates regularly since 2003. The objective of this study was to describe India's biennial HIV estimation 2017 process, data inputs, tool, methodology and epidemiological assumptions used to generate the HIV estimates and trends of key indicators for 2010-2017 at national and State/Union Territory levels. Methods: Demographic Projection (DemProj) and AIDS Impact Modules (AIM) of Spectrum 5.63 software recommended by the United Nations Programme on HIV and AIDS Global Reference Group on HIV Estimates, Modelling and Projections, were used for generating HIV estimations on key indicators. HIV sentinel surveillance, epidemiological and programme data were entered into Estimation Projection Package (EPP), and curve fitting was done using EPP classic model. Finally, calibration was done using the State HIV prevalence of two rounds of National Family Health Survey (NFHS) -3 and -4 and Integrated Biological and Behavioural Surveillance (IBBS), 2014-2015. Results: The national adult prevalence of HIV was estimated to be 0.22 per cent in 2017. Mizoram, Manipur and Nagaland had the highest prevalence over one per cent. An estimated 2.1 million people were living with HIV in 2017, with Maharashtra estimated to have the highest number. Of the 88 thousand annual new HIV infections estimated nationally in 2017, Telangana accounted for the largest share. HIV incidence was found to be higher among key population groups, especially people who inject drugs. The annual AIDS-related deaths were estimated to be 69 thousand nationally. For all indicators, geographic variation in levels and trends between States existed. Interpretation & conclusions: With a slow decline in annual new HIV infections by only 27 per cent from 2010 to 2017 against the national target of 75 per cent by 2020, the national target to end AIDS by 2030 may be missed; although at the sub-national level some States have made better progress to reduce new HIV infection. It calls for reinforcement of HIV prevention, diagnosis and treatment efforts by geographical regions and population groups.

The number of secondary cases from each primary case determines how fast an epidemic grows. It is known that all cases do not spread the infection equally; super spreaders play an important role as they contribute disproportionately to a much larger number of cases including in the ongoing COVID-19 pandemic. Super spreaders have been reported for more than a century, but limited information is available in scientific literature. An epidemic containment strategy needs to include early identification of super spreaders to limit an explosive growth. Super spreaders tend to get stigmatized, resulting in late reporting and hiding of cases. It is important for program managers to be sensitive to the manner in which related information is shared with media and general public.

BACKGROUND: Nutritional anemia due to iron deficiency is the most common cause of anemia in India. The average diet in India is low in iron and mostly of vegetable origin. This can be improved by increasing awareness of foodstuffs that are rich in iron and ensuring their availability. OBJECTIVE: The objective of the study was to assess the quality of information available on iron-rich foods and to assess their production and consumption in India. METHODS: This was a review of common textbooks for medical, nursing, and home science students; related policy and program documents; and government publications on production and consumption of various foodstuffs in India. RESULTS: Details of specific foods that are rich in iron have not been provided. Instead, food groups such as pulses, cereals, nuts, and green leafy vegetables (GLVs) have been mentioned that are good sources of non-heme iron. This is in spite of the fact that all the foodstuffs in these groups are not uniformly iron rich. Among cereals and pulses, rice and red gram dal (arhar) are the most commonly produced and consumed, though they have the lowest iron content. Spinach and mustard leaves believed to be iron rich and commonly consumed are among those GLVs having lowest iron content. CONCLUSION: Details of 5-10 foodstuffs which have the highest iron content within each food group should be available in relevant books and documents meant for education, production, and consumption data.

BACKGROUND: During HIV sentinel surveillance (HSS) 2017 round, the sampling strategy to recruit female sex workers (FSWs) was changed from consecutive to random sampling. This may affect the participation and HIV positivity rates among FSWs. OBJECTIVE: The objective of this study is to estimate the nonparticipation rates among FSWs and its effect on the observed HIV prevalence rate during HSS-2017. METHODS: The data were collected from FSW sentinel sites located in the states of Delhi, Jharkhand, Uttar Pradesh, and Uttarakhand (Central Zone). The HIV positivity rate among FSWs who participated in HSS-2017 was compared with the HIV positivity rate of those who did not participate. HIV status of the participants was obtained from HSS-2017 data. The master list of participating targeted intervention sites was accessed to obtain the last known HIV status of the eligible nonparticipants. RESULTS: Nonparticipation rate of FSWs from the central zone during HSS2017 was 10.8%. The HIV positivity rate among nonparticipant FSW was four times and six times higher in Delhi and UP, respectively. CONCLUSION: Selective nonparticipation of eligible FSWs might have led to the underestimation of the HIV positivity rate in the central zone during the HSS-2017 round.

BACKGROUND: Quality of HIV sentinel surveillance (HSS) depends on preparedness of the site and adherence to the standard operating procedures (SOPs) for HSS. A designated sentinel site is considered prepared for the round of sentinel surveillance based on the availability of infrastructure, human resource, and consumables. OBJECTIVES: The study objectives were to describe the site level preparedness and adherence to SOP of antenatal care clinic (ANC) sites during the 16th round of HSS in India. METHODS: This was a cross-sectional study based on the findings of the supervisory visits conducted by public health specialists in ANC sites during the 16th round of HSS from January to March 2019. Semi-structured checklists were used to assess site-preparedness and adherence to the SOP for HSS. All supervisors were expected to upload the filled pro forma to the HSS management information system (MIS). We present here a descriptive analysis of the uploaded visit reports. RESULTS: Of 870 HSS sites, 783 (90%) were visited, and 479 (61.2%) reports were uploaded to MIS. Preround HSS training was not attended by one-fifth (22.6%) of the site in-charges; 35.8% of them had never received any HSS training. SOP was followed at most (94%) of the sites. The most frequently reported problem at the sites was inadequate or delayed availability of consumables. CONCLUSION: The overall quality of site-level preparedness at antenatal clinic sites in India was good. Attention needs to be given to timely and adequate availability of consumables at sentinel sites along with proper administrative support and preround training of site in-charges.

BACKGROUND: In 2017, the sampling procedure for HIV sentinel surveillance (HSS) among all high-risk groups was changed from the consecutive sampling to random sampling along with the introduction of linked anonymous testing strategy with informed written consent. OBJECTIVE: The objective of this study was to assess whether the inclusion of informed consent affects the HIV positivity rate among the participants and nonparticipants injecting drug users (IDU) in HSS 2017 in four states of Central Zone of India. METHODS: This study was a cross-sectional study. All sentinel sites from Delhi, Uttar Pradesh, Jharkhand, and Uttarakhand located at targeted intervention facilities in 2017 were included in the study. Information about the participation and nonparticipation of each high-risk individual at the sentinel site was gathered from the master list, respective registers, and website portal of the National AIDS Control Organization. A total of 8639 individuals were included in the analysis. RESULTS: Overall, 16 sites in four states were included in the study. Overall, the nonparticipation rate of IDUs was 14.3%; highest being for Delhi (17.2%), followed by Uttar Pradesh (14.6%), Uttarakhand (10.9%), and Jharkhand (4.4%). Overall, the HIV-positivity rate among nonparticipants (9.6%) was significantly higher (P = 0.009) compared to the participants (6.7%). CONCLUSION: Change in methodology and seeking written informed consent might have an effect on the nonparticipation in all four states. This, in turn, could have led to the underestimation of HIV-positivity rates among IDU in the states.

MAIN CONCLUSION: UV-B-induced flavonoid biosynthesis is epigenetically regulated by site-specific demethylation of AaMYB1, AaMYC, and AaWRKY TF-binding sites inAaPAL1promoter-causing overexpression ofAaPALgene inArtemisia annua. The present study was undertaken to understand the epigenetic regulation of flavonoid biosynthesis under the influence of ultraviolet-B radiation using Artemisia annua L. as an experimental model. In-vitro propagated and acclimatized plantlets were treated with UV-B radiation (2.8 W m-2; 3 h), which resulted in enhanced accumulation of total flavonoid and phenolics content as well as eleven individual flavonoids measured through HPLC-DAC. Expression of eight genes (phenylanaline ammonia lyase, cinnamate-4-hydroxylase, 4-coumarate: CoA ligase; chalcone synthase, chalcone isomerase, cinnamoyl reductase, flavonoid-3'-hydroxylase, and flavones synthase) from upstream and downstream flavonoid biosynthetic pathways was measured through RT-PCR and RT-Q-PCR and all were variably induced under UV-B irradiation. Among them, AaPAL1 transcript and its protein were most significantly upregulated. Global DNA methylation analysis revealed hypomethylation of genomic DNA in A. annua. Further epigenetic characterization of promoter region of AaPAL1 revealed cytosine demethylation at five sites, which in turn caused epigenetic activation of six transcription factor-binding sites including QELEMENT, EBOXBNNAPA/MYCCONSENSUSAT, MYBCORE, MYBCOREATCYCB1, and GCCCORE. MYB transcription factors are positive regulators of flavonoid biosynthesis. Epigenetic activation of transcription-enhancing cis-regulatory elements in AaPAL1 promoter and subsequent overexpression of AaMYB1 and AaMYC and AaWRKY transcription factors under UV-B irradiation may probably be the reason for higher AaPAL1 expression and hence greater biosynthesis of flavonoids in A. annua L. The present study is the first report that provides mechanistic evidence of epigenetic regulation of flavonoid biosynthesis under UV-B radiation in A. annua L.

Landmine blast injuries are high velocity shattering injuries that produce ghastly and gory wounds, presenting a dilemma to the treating surgeon, especially when the literature on this subject is limited. The aim of the present study is to enlist various surgical procedures that can be explored to treat such complex injuries. 60 cases having varied degrees of involvement of the lower limb from mine blasts were managed. Surgical treatment was tailored to the individual requirement depending on the extent and severity of injury. Serial surgical wound debridement was an integral part of all these procedures. Limb length preservation was possible in 70% cases. A combination of surgical approaches and procedures from fixation to different types of amputations can be employed for treating mine blast injuries to maximise residual limb function.

BACKGROUND: Socio-economic inequity leads to health inequity. Inequity is closely intertwined with internal migration. This study was planned with the objective of documenting the maternal health care utilization among women labourers working in brick kilns situated in an area of Haryana, north India. METHODS: A community based mixed method study was done in select brick kilns of Faridabad district in north India. A mixed method study was done to assess maternal health care utilization in a sample of 500 women in the reproductive age group. Focus group discussions were also carried out. Descriptive analysis was done. Qualitative data was analysed using the thematic framework approach. RESULTS: The mean age of the women was 30 (SD 0.3) years. Mean number of pregnancies per woman was 3.1 (SD 1.7). Only 22.9% ever had institutional delivery. About one third of women had ever received cash benefit under Janani SurakshaYojana (JSY) or had ever used free ambulance services. Seven major themes emerged from the qualitative analysis. Important themes include-Gaps in knowledge regarding local health system; Sub-standard private health care delivered at brick kilns prevent migrants from accessing the basic public health services; Misconceptions and mistrust about public health system influenced maternal health care utilization; Barriers to avail universal health coverage: location of brick kilns, time, apathy of public health system, partial health insurance cover. CONCLUSIONS: A typical migrant woman labourer in the brick kiln was an illiterate, had migrated from poor states, belonged to a socially disadvantaged community and worked long hours, and had been doing so for many years. This study has identified migrant women working in brick kilns as a vulnerable population subgroup in terms of maternal health utilization. To achieve universal health care it is important to understand the needs of all population subgroups and make concerted efforts at the health system level.

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.

Background: Globally, around 1 billion persons are disabled as per the WHO report on disability in 2011. The bio-psycho-social model of disability was developed by the WHO as the International Classification of Functioning, Disability and Health. We studied the prevalence of disability and its association with sociodemographic factors and quality of life among adults in a rural area. Methods: We did a community-based, cross-sectional study among 418 randomly selected adult participants aged 18 years and above in a rural area of Ballabgarh, Haryana. Participants were interviewed by administering WHO Disability Assessment Schedule 2.0 (WHODAS 2.0) for assessing disability and WHO Quality of Life-BREF (WHOQOL-BREF) scale for assessing quality of life. Multivariate analyses were done for the predictors of disability. Correlation was applied to find the association between disability and quality of life. Results: The prevalence of disability was 7.7% (95% confidence interval [CI]: 5.3%-10.6%) based on the cut-off > 40 summary score. More women (10.9%) than men (4.1 %) were disabled (p = 0.009). Being ≥60 years of age was independently associated with disability (adjusted odds ratio 12.3; 95% CI 4.45-33.97). The mean (SD) of the WHOQOL-BREF health-related quality of life (HRQOL) summary score was 67.6 (11.6) and the median was 66.43. HRQOL summary scores decreased as age increased. There was a negative correlation between summary scores of WHODAS 2.0 and WHOQOL-BREF (r -0.57, p<0.001). Conclusion: Prevalence of disability was higher than the estimate given by Census 2011. The elderly and women experience more disability. As age increases, quality of life decreases. Increase in the level of disability decreases the quality of life.

Background: Planning a comprehensive program addressing neonatal mortality will require a detailed situational analysis of available neonatal-specific health infrastructure. Methods: We identified facilities providing essential and sick neonatal care (ENC, SNC) by a snowballing technique in Ballabgarh Block. These were assessed for infrastructure, human resource and equipment along with self-rated competency of the staff and compared with facility-based or population-based norms. Results: A total of 35 facilities providing ENC and 10 facilities for SNC were identified. ENC services were largely in the public-sector domain (68.5% of births) and were well distributed in the block. SNC burden was largely being borne by the private sector (66% of admissions), which was urban-based. The private sector and nurses reported lower competency especially for SNC. Only 53.9% of government facilities and 17.5% of private facilities had a fully equipped newborn care corner. Conclusions: Serious efforts to reduce neonatal mortality would require major capacity strengthening of the health system, including that of the private sector.
