After informed consent, individuals attending 3 STI clinics were administered a questionnaire regarding their demographic, socioeconomic, and sexual behaviors. Blood samples were collected for STI and HIV diagnosis. Bivariate and multivariate analyses were performed to determine the correlates of HIV infection. The prevalence of HIV (45.2% in Hijras vs 20% in heterosexual men vs 18.9% in MSM, P < 0.0001) and warts (10.3% vs 4.6% vs 7.0%; P = 0.004) was higher in Hijras as compared with heterosexual men and MSM; whereas that of genital ulcer disease (15.3% vs 32.6% vs 21.5%; P < 0.0001) and discharge (5.4% vs 13.6% vs 9.0%; P < 0.0001) was lower. Hijras were more likely to have received money for sex and have an earlier sexual debut than the comparison groups. In multivariate analysis, receiving money for sex (adjusted odds ratio: 4.49; P < 0.04) and having genital ulcer disease (odds ratio: 3.87; P < 0.08) were independently associated with high HIV prevalence in Hijras. Considering the high HIV and STI burden, it is important to review current prevention strategies and stress the need to engage Hijra community members through appropriate targeted intervention programs.

Investigations conducted during 2005 identified Japanese encephalitis (JE) virus as an aetiology of AES. With the introduction of JE vaccination and other control strategies, the incidence of JE in the region declined, however, outbreaks of acute febrile illness with neurological manifestations continued to occur. Subsequent investigations identified Orientia tsutsugamushi, as the major aetiology of AES outbreaks in the region. This review details clinical, epidemiological, animal and entomological investigations conducted for AES due to O. tsutsugamushi during 2015 and 2017 in Gorakhpur region. Surveillance of acute febrile illness among children attending peripheral health facilities identified scrub typhus as an important aetiology of febrile illness during monsoon and post-monsoon months. Population-based serosurveys indicated high endemicity of scrub typhus. Entomological studies demonstrated natural infection of O. tsutsugamushi in small animal hosts and vector mites. Children acquired this infection through recent exposure to outdoor environment, while playing, or visiting fields or defecating in open fields. A few of the children with scrub typhus progress to develop CNS manifestations. Hence, early administration of appropriate antibiotics is crucial in preventing progression of AFI due to scrub typhus to AES. The investigations conducted by the multi-disciplinary team helped understand the transmission dynamics of scrub typhus in Gorakhpur division and recommend strategies for its control.

The aim of this study is to describe the impact of genetic polymorphisms of GSTM1, GSTT1 and GSTP1-313A/G in the risk of ARV-associated hepatotoxicity in HIV-infected individuals and its modulation in hepatotoxic patients. We enrolled a total of 34 patients with hepatotoxicity, 131 HIV-infected individuals without hepatotoxicity under non-nucleoside reverse transcriptase inhibitor containing ART and 153 unrelated healthy individuals. With a case-control design, polymorphisms of GSTM1, GSTT1 and GSTP1-313A/G gene were genotyped by PCR and restriction enzyme-length polymorphism. Genotypes of GSTT1 null were significantly higher in HIV-infected individuals as compared with healthy controls (P=0.01, odds ratio (OR)=1.54). HIV-infected individuals with GSTM1-null genotype showed higher risk (P=0.09, OR=1.37) for hepatotoxicity, but risk was not significant. On evaluating gene-gene interaction models, GSTM1 null and GSTT1 null showed significant association with the risk of hepatotoxicity in HIV-infected individuals (P=0.004, OR=2.67) owing to synergistic effect of these genes. Individuals with GSTT1-null and GSTM1-null genotypes showed higher risk of hepatotoxicity with advanced stage of (CD4<200) of HIV infection (P=0.18, OR=1.39; P=0.63, OR=1.13). In case-only analysis, GSTT1-null genotype among alcohol users showed elevated risk of hepatotoxicity in HIV-infected individuals (P=0.12, OR=1.36, 95% confidence interval (CI): 0.94-1.97) as compared with GSTT1 genotypes. The carriers GSTM1-null+GSTT1-null genotype among nevirapine user showed prominent risk of hepatotoxicity in HIV-infected individuals (P=0.12, OR=4.21, 95% CI: 0.60-29.54). Hence, we can conclude that GSTT1-null and GSTM1-null genotypes alone and in combination may predict the acquisition of hepatotoxicity.The Pharmacogenomics Journal advance online publication, 15 December 2015; doi:10.1038/tpj.2015.88.

A study was conducted to understand factors and influencers of adherence to ART and their follow ups among patients attending ART centres in Maharashtra, India. Methods: Between January and March 2009, barriers to ART adherence among 32 patients at three selected ART centres functioning under national ART roll-out programme in Maharashtra, India, were studied using qualitative methods. Consenting patients were interviewed to assess barriers to ART adherence. Constant comparison method was used to identify grounded codes. Results: Patients reported multiple barriers to ART adherence and follow up as (i) Financial barriers where the contributing factors were unemployment, economic dependency, and debt, (ii) social norm of attending family rituals, and fulfilling social obligations emerged as socio-cultural barriers, (iii) patients' belief, attitude and behaviour towards medication and self-perceived stigma were the reasons for suboptimal adherence, and (iv) long waiting period, doctor-patient relationship and less time devoted in counselling at the center contributed to missed visits. Interpretation & conclusions: Mainstreaming ART can facilitate access and address 'missed doses' due to travel and migration. A 'morning' and 'evening' ART centre/s hours may reduce work absenteeism and help in time management. Proactive 'adherence probing' and probing on internalized stigma might optimize adherence. Adherence probing to prevent transitioning to suboptimal adherence among patients stable on ART is recommended.

A third serosurvey was conducted between December 2020 and January 2021 to estimate the seroprevalence of SARS-CoV-2 infection among the general population and healthcare workers (HCWs) in India. Methods: The third serosurvey was conducted in the same 70 districts as the first and second serosurveys. For each district, at least 400 individuals aged !10 years from the general population and 100 HCWs from subdistrict-level health facilities were enrolled. Serum samples from the general population were tested for the presence of immunoglobulin G (IgG) antibodies against the nucleocapsid (N) and spike (S1-RBD) proteins of SARS-CoV-2, whereas serum samples from HCWs were tested for anti-S1-RBD. Weighted seroprevalence adjusted for assay characteristics was estimated. Results: Of the 28,598 serum samples from the general population, 4585 (16%) had IgG antibodies against the N protein, 6647 (23.2%) had IgG antibodies against the S1-RBD protein, and 7436 (26%) had IgG antibodies against either the N protein or the S1-RBD protein. Weighted and assay-characteristicadjusted seroprevalence against either of the antibodies was 24.1% [95% confidence interval (CI) 23.0-25.3%]. Among 7385 HCWs, the seroprevalence of anti-S1-RBD IgG antibodies was 25.6% (95% CI 23.5-27.8%). Conclusions: Nearly one in four individuals aged !10 years from the general population as well as HCWs in India had been exposed to SARS-CoV-2 by December 2020.

We did the fourth nationwide serosurvey to estimate prevalence of SARS-CoV-2 antibodies in the general population aged >=6 years and health care workers (HCWs). Methods: We did a cross-sectional study between 14 June and 6 July 2021 in 700 clusters in the same 70 districts across 21 states/Union Territory. From each district, a minimum of 400 individuals aged >=6 years from general population and 100 HCWs from the district public health facilities were included. The serum samples were tested for the presence of IgG antibodies against S1-RBD and nucleocapsid protein of SARS-CoV-2 using chemiluminescence immunoassay. We estimated the weighted and test adjusted seroprevalence of IgG antibodies against S1-RBD and/or nucleocapsid protein along with 95% CI. Findings: Of the 28,975 sera tested, the weighted and test adjusted prevalence of IgG antibodies against S1-RBD and/or nucleocapsid protein among the general population aged >=6 years was 67.6% (95% CI: 66.4 – 68.7). The seroprevalence increased with age and was not different in rural and urban areas. Compared to unvaccinated adults (62.3%, 95% CI: 60.9 – 63.7), seroprevalence was significantly higher among individuals who received one (81.0%, 95% CI: 79.6 - 82.3) and two doses (89.8%, 95% CI: 88.4 - 91.1). The seroprevalence of IgG antibodies among 7,252 health care workers was 85.2% (95% CI: 83.5 - 86.7). Interpretation: Nearly one third of the population is still seronegative. It is necessary to accelerate the coverage of COVID-19 vaccination among adults and continue adherence to non-pharmaceutical interventions. Funding: Indian Council of Medical Research. Declaration of Interest: None to declare. Ethical Approval: The Institutional Human Ethics Committee of the ICMR National Institute of Epidemiology, Chennai approved the study protocol.

We aimed to assess the more recent nationwide seroprevalence in the general population in India. Methods We did a second household serosurvey among individuals aged 10 years or older in the same 700 villages or wards within 70 districts in India that were included in the first serosurvey. Individuals aged younger than 10 years and households that did not respond at the time of survey were excluded. Participants were interviewed to collect information on sociodemographics, symptoms suggestive of COVID-19, exposure history to laboratoryconfirmed COVID-19 cases, and history of COVID-19 illness. 3-5 mL of venous blood was collected from each participant and blood samples were tested using the Abbott SARS-CoV-2 IgG assay. Seroprevalence was estimated after applying the sampling weights and adjusting for clustering and assay characteristics. We randomly selected one adult serum sample from each household to compare the seroprevalence among adults between the two serosurveys. Findings Between Aug 18 and Sept 20, 2020, we enrolled and collected serum samples from 29 082 individuals from 15 613 households. The weighted and adjusted seroprevalence of SARS-CoV-2 IgG antibodies in individuals aged 10 years or older was 6•6% (95% CI 5•8-7•4). Among 15 084 randomly selected adults (one per household), the weighted and adjusted seroprevalence was 7•1% (6•2-8•2). Seroprevalence was similar across age groups, sexes, and occupations. Seroprevalence was highest in urban slum areas followed by urban non-slum and rural areas. We estimated a cumulative 74•3 million infections in the country by Aug 18, 2020, with 26-32 infections for every reported COVID-19 case. Interpretation Approximately one in 15 individuals aged 10 years or older in India had SARS-CoV-2 infection by Aug 18, 2020. The adult seroprevalence increased approximately tenfold between May and August, 2020. Lower infection-to-case ratio in August than in May reflects a substantial increase in testing across the country.

DV prevention interventionsare critical in the armamentarium of India’s HIV prevention strategies and developing and validating a culturally-tailored instrument is necessary to evaluate the effectiveness of such strategies. We hypothesized that currently available DV scales fall short in capturing DV among Indian women because of differences in Indian family structure, in readily-available tools to inflict physical DV, and the normalization and acceptance of DV. We developedand tested a culturally-tailored scale that more effectively measures DV in the Indian context. Methods: We conducted a mixed-methods study between September 2012 and June 2013 in Pune, Indiaafter obtaining approval from the institutional ethics committee. This included 1) a formative phase consisting of a systematic literature review, focus g...

Totals of 116 and 129 polymorphic variants were recorded in Punjabis and Rajputs respectively. The frequency of large-C-band variants was equal in Punjabis (n = 67) and Rajputs (n = 66) whereas the frequency of small-C-band variants was different (47 in Punjabis, 58 in Rajputs). Inversion of the 9qh region was more common in Rajputs than Punjabis. These polymorphic variants were predominantly localised near the secondary constriction regions of chromosomes 1,9 and 16. each person's karyotype might prove to differ from everyone else's (Friedrich et al., 1977). Miiller (1975) in a recent study of a human newborn population observed that no two individuals were alike with respect to the C-band pattern. The C-band variants retain their integrity in an individual and this character is inherited as a stable unit in the regular Mendefan manner (Craig-Holmes et al., 1975; Robinson et al., 1976; Philips, 1977; Magenis et al., 1977) although preferential segregation of certain polymorphic vari

The study used qualitative methods to examine the experiences of 31 women during late pregnancy, delivery and at post-natal visits. It also elicited the perspectives of 19 healthcare providers. Frequent visits required during late-pregnancy and the post-natal period presented concerns for the women in the study. Women's understanding of the long-term implications of participating in the intervention study was poor, and living with uncertainty about the HIV status of the newborn was a major concern. The provision of psychosocial support is essential in future intervention studies and should be incorporated on an ongoing basis. Networking with women-centred support groups may be helpful in enabling women to gain the long-term benefits of this type of intervention.

A third serosurvey was conducted between December 2020 and January 2021 to estimate the seroprevalence of SARS-CoV-2 infection among the general population and healthcare workers (HCWs) in India. Methods: The third serosurvey was conducted in the same 70 districts as the first and second serosurveys. For each district, at least 400 individuals aged !10 years from the general population and 100 HCWs from subdistrict-level health facilities were enrolled. Serum samples from the general population were tested for the presence of immunoglobulin G (IgG) antibodies against the nucleocapsid (N) and spike (S1-RBD) proteins of SARS-CoV-2, whereas serum samples from HCWs were tested for anti-S1-RBD. Weighted seroprevalence adjusted for assay characteristics was estimated. Results: Of the 28,598 serum samples from the general population, 4585 (16%) had IgG antibodies against the N protein, 6647 (23.2%) had IgG antibodies against the S1-RBD protein, and 7436 (26%) had IgG antibodies against either the N protein or the S1-RBD protein. Weighted and assay-characteristicadjusted seroprevalence against either of the antibodies was 24.1% [95% confidence interval (CI) 23.0-25.3%]. Among 7385 HCWs, the seroprevalence of anti-S1-RBD IgG antibodies was 25.6% (95% CI 23.5-27.8%). Conclusions: Nearly one in four individuals aged !10 years from the general population as well as HCWs in India had been exposed to SARS-CoV-2 by December 2020.

We did the fourth nationwide serosurvey to estimate prevalence of SARS-CoV-2 antibodies in the general population aged >=6 years and health care workers (HCWs). Methods: We did a cross-sectional study between 14 June and 6 July 2021 in 700 clusters in the same 70 districts across 21 states/Union Territory. From each district, a minimum of 400 individuals aged >=6 years from general population and 100 HCWs from the district public health facilities were included. The serum samples were tested for the presence of IgG antibodies against S1-RBD and nucleocapsid protein of SARS-CoV-2 using chemiluminescence immunoassay. We estimated the weighted and test adjusted seroprevalence of IgG antibodies against S1-RBD and/or nucleocapsid protein along with 95% CI. Findings: Of the 28,975 sera tested, the weighted and test adjusted prevalence of IgG antibodies against S1-RBD and/or nucleocapsid protein among the general population aged >=6 years was 67.6% (95% CI: 66.4 – 68.7). The seroprevalence increased with age and was not different in rural and urban areas. Compared to unvaccinated adults (62.3%, 95% CI: 60.9 – 63.7), seroprevalence was significantly higher among individuals who received one (81.0%, 95% CI: 79.6 - 82.3) and two doses (89.8%, 95% CI: 88.4 - 91.1). The seroprevalence of IgG antibodies among 7,252 health care workers was 85.2% (95% CI: 83.5 - 86.7). Interpretation: Nearly one third of the population is still seronegative. It is necessary to accelerate the coverage of COVID-19 vaccination among adults and continue adherence to non-pharmaceutical interventions. Funding: Indian Council of Medical Research. Declaration of Interest: None to declare. Ethical Approval: The Institutional Human Ethics Committee of the ICMR National Institute of Epidemiology, Chennai approved the study protocol.

We aimed to assess the more recent nationwide seroprevalence in the general population in India. Methods We did a second household serosurvey among individuals aged 10 years or older in the same 700 villages or wards within 70 districts in India that were included in the first serosurvey. Individuals aged younger than 10 years and households that did not respond at the time of survey were excluded. Participants were interviewed to collect information on sociodemographics, symptoms suggestive of COVID-19, exposure history to laboratoryconfirmed COVID-19 cases, and history of COVID-19 illness. 3-5 mL of venous blood was collected from each participant and blood samples were tested using the Abbott SARS-CoV-2 IgG assay. Seroprevalence was estimated after applying the sampling weights and adjusting for clustering and assay characteristics. We randomly selected one adult serum sample from each household to compare the seroprevalence among adults between the two serosurveys. Findings Between Aug 18 and Sept 20, 2020, we enrolled and collected serum samples from 29 082 individuals from 15 613 households. The weighted and adjusted seroprevalence of SARS-CoV-2 IgG antibodies in individuals aged 10 years or older was 6•6% (95% CI 5•8-7•4). Among 15 084 randomly selected adults (one per household), the weighted and adjusted seroprevalence was 7•1% (6•2-8•2). Seroprevalence was similar across age groups, sexes, and occupations. Seroprevalence was highest in urban slum areas followed by urban non-slum and rural areas. We estimated a cumulative 74•3 million infections in the country by Aug 18, 2020, with 26-32 infections for every reported COVID-19 case. Interpretation Approximately one in 15 individuals aged 10 years or older in India had SARS-CoV-2 infection by Aug 18, 2020. The adult seroprevalence increased approximately tenfold between May and August, 2020. Lower infection-to-case ratio in August than in May reflects a substantial increase in testing across the country.

DV prevention interventionsare critical in the armamentarium of India’s HIV prevention strategies and developing and validating a culturally-tailored instrument is necessary to evaluate the effectiveness of such strategies. We hypothesized that currently available DV scales fall short in capturing DV among Indian women because of differences in Indian family structure, in readily-available tools to inflict physical DV, and the normalization and acceptance of DV. We developedand tested a culturally-tailored scale that more effectively measures DV in the Indian context. Methods: We conducted a mixed-methods study between September 2012 and June 2013 in Pune, Indiaafter obtaining approval from the institutional ethics committee. This included 1) a formative phase consisting of a systematic literature review, focus g...

It also infected person. The study is still on-going in order to assess the durability of these effects.

Totals of 116 and 129 polymorphic variants were recorded in Punjabis and Rajputs respectively. The frequency of large-C-band variants was equal in Punjabis (n = 67) and Rajputs (n = 66) whereas the frequency of small-C-band variants was different (47 in Punjabis, 58 in Rajputs). Inversion of the 9qh region was more common in Rajputs than Punjabis. These polymorphic variants were predominantly localised near the secondary constriction regions of chromosomes 1,9 and 16. each person's karyotype might prove to differ from everyone else's (Friedrich et al., 1977). Miiller (1975) in a recent study of a human newborn population observed that no two individuals were alike with respect to the C-band pattern. The C-band variants retain their integrity in an individual and this character is inherited as a stable unit in the regular Mendefan manner (Craig-Holmes et al., 1975; Robinson et al., 1976; Philips, 1977; Magenis et al., 1977) although preferential segregation of certain polymorphic vari

The study used qualitative methods to examine the experiences of 31 women during late pregnancy, delivery and at post-natal visits. It also elicited the perspectives of 19 healthcare providers. Frequent visits required during late-pregnancy and the post-natal period presented concerns for the women in the study. Women's understanding of the long-term implications of participating in the intervention study was poor, and living with uncertainty about the HIV status of the newborn was a major concern. The provision of psychosocial support is essential in future intervention studies and should be incorporated on an ongoing basis. Networking with women-centred support groups may be helpful in enabling women to gain the long-term benefits of this type of intervention.
