RESUMEN

INTRODUCTION: India's contribution to the malaria burden was highest in South-East Asia Region in 2021, accounting for 79% of the estimated malaria cases and 83% of malaria-related deaths. Intensified Malaria Control Programme supported by Global Funds to Fight against AIDS, Tuberculosis and Malaria has deployed crucial interventions to reduce the overall burden of malaria in India. Evaluation of utilisation of malaria elimination interventions by the community and assessment of the healthcare system is underway in eleven high malaria endemic states in India. Health system preparedness for malaria elimination, logistics, and supply chain management of diagnostic kits and anti-malarial drugs in addition to the knowledge, attitude and practice of the healthcare workers is also being assessed. METHODS AND ANALYSIS: The study is being undertaken in 11 malaria endemic states with a variable annual parasite incidence of malaria. In total, 47 districts (administrative unit of malaria control operations) covering 37 976 households are to be interviewed and assessed. We present here the protocol following which the study is being undertaken at the behest and approval of Ministry of Health and Family Welfare in India. ETHICS AND DISSEMINATION: No patients were involved in the study. Study findings will be shared with Institutional ethics board of National Institute for Malaria Research New Delhi (NIMR) in a timely, comprehensive, accurate, unbiased, unambiguous and transparent manner and to the National Vector-borne Disease (Malaria) Control Programme officers and the Community public who participated. Important findings will be communicated through community outreach meetings which are existing in the Health system. Results will be informed to study participants via local fieldwork supervised by District Malaria Officers. Also findings will be published in reputed journals based on Indian Council of Medical Research (ICMR) publication policy.The ICMR-NIMR ethics committee approved the study via letter No. NIMR/ECM/2023/Feb/14 dated 24 April 2023 for version 5. All standard ethical practices will be followed.

RESUMEN

African swine fever (ASF) is a highly contagious, notifiable, and fatal hemorrhagic viral disease affecting domestic and wild pigs. The disease was reported for the first time in India during 2020, resulted in serious outbreaks and economic loss in North-Eastern (NE) parts, since 47% of the Indian pig population is distributed in the NE region. The present study focused on analyzing the spatial autocorrelation, spatio-temporal patterns, and directional trend of the disease in NE India during 2020-2021. The ASF outbreak data (2020-2021) were collected from the offices of the Department of Animal Husbandry and Veterinary Services in seven NE states of India to identify the potential clusters, spatio-temporal aggregation, temporal distribution, disease spread, density maps, and risk zones. Between 2020 and 2021, a total of 321 ASF outbreaks were recorded, resulting in 59,377 deaths. The spatial pattern analysis of the outbreak data (2020-2021) revealed that ASF outbreaks were clustered in 2020 (z score = 2.20, p < .01) and 2021 (z score = 4.89, p < .01). Spatial autocorrelation and Moran's I value (0.05-0.06 in 2020 and 2021) revealed the spatial clustering and spatial relationship between the outbreaks. The hotspot analysis identified districts of Arunachal Pradesh, Assam and districts of Mizoram, Tripura as significant hotspots in 2020 and 2021, respectively. The spatial-scan statistics with a purely spatial and purely temporal analysis revealed six and one significant clusters, respectively. Retrospective unadjusted, temporal, and spatially adjusted space-time analysis detected five, five, and two statistically significant (p < .01) clusters, respectively. The directional trend analysis identified the direction of disease distribution as northeast-southwest (2020) and north-south (2021), indicate the possibility of ASF introduction to India from China. The high-risk zones and spatio-temporal pattern of ASF outbreaks identified in the present study can be used as a guide for deploying proper prevention, optimizing resource allocation and disease control measures in NE Indian states.

RESUMEN

OBJECTIVE: This study aimed to determine the prevalence and predictors of poor body image and its influence on low self-esteem and depression in middle-aged women. METHODS: The study was a cross-sectional survey of 372 women using a predesigned online questionnaire. Main outcome measures were mean scores on the nine-point body image scale (BIS) and prevalence of poor body image (BIS ≥ 10). Significant sociodemographic, physical and mental health predictors of BIS ≥ 10 were established using logistic regression analysis. Correlation of body image with self-esteem, assessed by Rosenberg's self-esteem scale, and depression, assessed by Beck's Depression Inventory, was established using Pearson's correlation coefficient and the odds ratios were determined using logistic regression analysis. RESULTS: The mean scores obtained for body image were 5.52 (standard deviation 4.82) and the prevalence of BIS ≥ 10 was 17.4%. Significant predictors of poor body image were education status (0.59, 95% confidence interval [CI] = 0.39-0.89), body mass index (2.26, 95% CI = 1.12-4.55), social support structure (0.35, 95% CI = 0.16-0.79), diagnosis of mental illness (3.74, 95% CI = 1.31-10.66) and perception of menopause (positive vs. negative: 0.20, 95% CI = 0.07-0.55). Body image scores correlated with self-esteem (r = -0.46; 95% CI = -0.54 to -0.38) and depression (r = 0.59; 95% CI = 0.52-0.65). BIS ≥ 10 significantly increased the odds of low self-esteem (5.71; 95% CI = 2.66-12.26) and depression (11.25; 95% CI = 4.9-27.7). CONCLUSIONS: The prevalence of poor body image in middle-aged women was 17.4%. This strongly correlated with low self-esteem and depression. A lower education status, higher body mass index, a negative perception of menopause, poor social support structure and a history of mental health diagnosis increased the odds of poor body image prevalence in middle-aged women.

RESUMEN

Background: Hypertension (high blood pressure) during pregnancy has significant implications on maternal and perinatal morbidity and mortality. Tobacco use during pregnancy amplifies this burden and increases the risk of hypertensive disorders along with adverse birth outcomes. The current study aimed to evaluate the joint risk atpopulation-level of tobacco use and hypertension among pregnant women in India. Methodology: Data of 32,428 "currently pregnant" women aged 15-49 years was obtained from the National Family Health Survey (NFHS-4) 2015-16to estimate bivariate (tobacco user vs. non-user) and binomial logistic regression analysis in order to get odds ratios of having hypertension. The analysis included socio-demographic variables such as the respondent's age, type of residence, wealth index, and education status. Results: Prevalence of hypertension among pregnant tobacco users (7.5%) was significantly higher than that of non-users (6.1%). The unadjusted odds of having hypertension were 1.17 (95% CI: 1.02-1.35) times among tobacco users than non-users and increased with age (p < 0.001) and in rural areas (p = 0.02) after adjusting for other covariates. However, it varied inversely with education status (p > 0.05; NS) and wealth quintile (p = 0.01). Conclusion: The present study identifies the higher co-existence of hypertension among tobacco-using pregnant women and highlights the need for tobacco control/cessation and hypertension prevention and management during pregnancy considering socio-demographic disparities.

RESUMEN

The developed polymerase spiral reaction-based technique specifically amplified the ceuE gene of C. coli and involved a three-step centrifugation method for DNA extraction. PSR, real-time and end-point PCR were able to detect 62 fg, 620 fg and 6.2 pg C. coli DNA/tube, respectively. PSR detection limits for artificially contaminated pork samples without enrichment, with 12 h enrichment and after 24 h enrichment were 1000 CFU/g, 100 CFU/g, and 10 CFU/g samples, respectively which were ten times better than real-time PCR. The detection performance of PSR (with 12 h enrichment) was also compared to culture (ISO10272-1:2017) method using 75 naturally-contaminated samples, which revealed the sensitivity, specificity, PPV, NPV and accuracy of 100% (95%CI, 73.2%-100%), 98.4% (95%CI, 90%-99.9%), 93.3% (95%CI, 66%-99.6%), 100% (95%CI, 92.5%-100%) and 98.7% (95%CI, 92.8%-99.9%), respectively. The advantage and novelty of this assay are its equipment-free nature, dye-based interpretation by the naked eye, and the requirement of one enzyme and one primer pair. This assay could be a better alternative to other molecular methods and may help in reducing the possible troubles (e.g., gastroenteritis, hospitalization, or death) of belated detection of C. coli in food products. This is the primary report applying the PSR for C. coli detection.

RESUMEN

HYPOTHESIS: Although wetting agents have been developed to limit tear film dewetting over contact lenses, systematic analyses correlating wetting agent properties to mechanisms of the tear film destabilization are not readily available. Clarifying destabilization characteristics across key physio-chemical variables will provide a rational basis for identifying optimal wetting agents. EXPERIMENTS: We employ an in-house, in vitro platform to comprehensively evaluate drainage and dewetting dynamics of five wetting agents across seventeen different formulations and two model tear film solutions. We consider the film thickness evolution, film thickness at breakup, dewetted front propagation, and develop correlations to contact angle to compare the samples. FINDINGS: Zwitterionic wetting agents effectively stabilize the tear film by reducing the film thickness at the onset of dewetting, and delaying the propagation of dewetted regions across the lens. Furthermore, tuning wetting agent surface concentrations and utilizing binary mixtures of wetting agents can enhance wetting characteristics. Finally, despite disparities in wetting agent molecular properties, the time to dewet 50% of the lens scales linearly with the product of the receding contact angle and contact angle hysteresis. Hence, we fundamentally establish the importance of minimizing the absolute contact angle and contact angle hysteresis for effective wetting performance.

RESUMEN

Neonatal calf mortality is a major concern to livestock sector worldwide. Neonatal calf diarrhoea (NCD), an acute severe condition causes morbidity and mortality in calves. Amongst various pathogens involved in NCD, E. coli is considered as one of the major causes. The study was targeted to characterize E. coli isolates from neonatal calves for diarrhoeagenic Escherichia coli (DEC) types (pathotyping), antimicrobial resistance (AMR) profiling and to correlate with epidemiological parameters. From neonates, a total of 113 faecal samples were collected, out of that 308, lactose fermenting colonies were confirmed as E. coli. Pathotypable isolates (12.3%) were represented by STEC (6.1%), EPEC (2.9%), ETEC (1.9%), EAEC (0.9%) and EHEC (0.3%). Occurrence of STEC was more in non-diarrhoeic calves, whereas ETEC was observed more in diarrhoeic calves. EPEC occurrence was observed in both diarrhoeic and non-diarrhoeic calves. Fishers extract test showed no significant association for occurrence of DEC types to type of dairies, health status, species, breed, age and sex of neonatal calves. Two hundred and eighty isolates were tested for antimicrobial susceptibility. The isolates showed maximum resistance towards ampicillin (55.4%) followed by tetracycline (54.3%), while minimum resistance was observed towards meropenem (2.5%). Multidrug resistant E. coli isolates were found to be 139 (49.6%), and Extended-spectrum beta-lactamase (ESBL) producers were 120 (42.9%). DEC pathotypes like STEC, ETEC, EHEC and EAEC that are also multidrug resistant present in neonatal calves have zoonotic potential and hence are of public health significance.

RESUMEN

The study reports the multi-drug resistant (MDR), extended spectrum beta-lactamase (ESBL) producing and carbapenem resistant Escherichia coli (CRE) isolated from rescued sloth bear (Melursus ursinus), India. Non-duplicate faecal samples from 21 adult rescued sloth bears were collected at once during 2015-2016 and processed for isolation of E. coli and antibacterial susceptibility pattern. From 21 samples, 45 E. coli were isolated and on phenotypic screening, 23 were MDR, 17 were ESBL producers, and five were carbapenem-resistant (CR). Three E. coli isolates (6.67%, 3/45) showed no resistance, however 42 isolates (93.33%, 42/45) exhibited resistant to at least one antibiotics. The MDR isolates carried beta-lactamase, chloramphenicol, aminoglycosides, tetracycline, fluroquinolone, and sulphadimidine resistance genes. All the phenotypic ESBL producing isolates harbored blaCTX-M genes. On genotypic screening, three CRE (60.0%, 3/5) were positive for blaNDM carbapenemase gene and efflux pump-mediated carbapenem resistance was detected in two CRE isolates (40.0%, 2/5) which were negative for carbapenemase genes. The CRE isolates (n = 5) also co-harbored AMR genes like blaTEM-1, blaAmpC, qnrA, qnrB, qnrS, tetA, tetB and sulI. Virulence screening of the resistant isolates detected the presence of Stx1(n = 1), Stx2 (n = 3), eaeA (n = 4) and hlyA (n = 3) genes. Plasmid incompatibility (Inc) typing revealed that two isolates harboured blaNDM-5 gene on Incl1 and one isolate on IncF plasmid. Apart from the NDM gene, the plasmids also carried tetracycline, beta-lactamase and quinolone resistance genes. The plasmid multilocus sequence typing (pMLST) of the E. coli Incl1 plasmid showed the Sequence Type (ST) 297. This appears to be the first report of MDR, ESBL producing and blaNDM-5 genes on Incl1 and IncF plasmids from rescued sloth bear.

RESUMEN

A cross-sectional study on five organized pig farms was conducted to assess the faecal carriage of ESBL and blaNDM carbapenemase-producing E. coli in piglets and pig farmworkers. Faecal samples from piglets (n = 155) and pig farmworkers (n = 21) were processed for isolation and characterization of E. coli. A total of 124 E. coli isolates from piglets and 21 E. coli isolates pig farmworkers were recovered and screening for ESBL production showed that 44.4 % (55/124) of the isolates from piglets and 42.9 % (9/21) of the isolates from farmworkers were ESBL positive. The ESBL positive isolates from piglets and farmworkers harbored blaCTX-M and also co-harbored other beta-lactams, sulphonamide, quinolone and tetracycline resistance genes. Diarrhoeic (50%, 49/98) and crossbred piglets (52.7%, 39/74) harbored a significantly higher number of ESBL producing isolates than non-diarrhoeic (23.1 %, 6/26) and purebred piglets (32%, 16/50) (p < 0.05). Piglets and pig farmworkers harbored nine and two carbapenem-resistant isolates, respectively. Interestingly, two isolates from piglets and one isolate from farmworkers harbored the blaNDM gene. The blaNDM positive E. coli isolated from piglets and farmworkers of the same farm revealed similar antibacterial resistance patterns, resistant genes, sequence (ST-167) and plasmid type (IncX3). In India, carbapenems are not used in food animal treatment, hence carbapenem resistant E. coli in piglets possibly originated from the human contact or common environment and is of public health importance.

RESUMEN

Bluetongue (BT) is an infectious viral disease which affects a wide range of ruminants and was first reported in India in 1964. In view of the absence of comprehensive information on the BT status in India, this study presents the seroprevalence on BT in farm animals of India based-on a systematic review and meta-analysis. A systematic review was conducted to identify the published articles (2001-2018) reporting the seroprevalence of BT in sheep, goats, cattle, buffalo, camels, and Mithun (Bos frontalis) from India. From 409 research articles, 71 fulfilled the inclusion criteria and meta-analysis for proportions was carried out targeting the eligible studies. From these, 144 strata level data were extracted with a sample size of 14048 sheep, 14696 goats, 5218 cattle, 2653 buffaloes, 2062 camels, and 222 Mithun. Overall, the analyses showed that the BT seroprevalence of 43% (95% CI: 38-49%) in goats, 39% (95% CI: 33-46%) in sheep, 38% (95% CI: 25-45%) in cattle, 34% (95% CI: 20-51%) in buffaloes, 16% (95% CI: 10-22%) in camels, and 66% (95% CI: 17-95%) in Mithun. Furthermore, the meta-regression analysis suggested that serological tests, geographical region, and sample size were the prime moderators. Meta-analytic study indicates the BT seropositivity in 25.35 million sheep (95% CI: 21.5-29.9), 58 million goats (95% CI: 51.3-66.2), 66.8 million cattle (95% CI: 47.7-86), 37.0 million buffaloes (95% CI: 21.7-55.4), 0.06 million camels (95% CI: 0.04-0.09), and 0.19 million Mithun (95% CI: 0.05-0.28). The findings highlight the variation of BT seropositivity in different geographical regions of India.

RESUMEN

Sarcomas are rare, malignant bone and soft-tissue tumours of mesenchymal origin, and their overall incidence accounts for 1% and 0.2%, respectively, of all malignancies. The aim of this article is to provide a reference on the evolving management concepts and trends of treatment of adult sarcomas of the head and neck in a major head and neck sarcoma centre. Early diagnosis remains a challenge due to non-specific symptomatology. Imaging such as ultrasound (US), magnetic resonance (MRI), computed tomography (CT), and positron emission tomography (PET) CT assist with diagnosis and staging, and biopsy is essential for diagnosis, tumour differentiation, and grading. Staging is dependent on histological grade, size of tumour, and metastasis. Sarcomas spread via the haematogenous route. Adequate clearance of locoregional disease and prevention of distant micrometastases are key to improved disease-free survival outcomes so multimodal treatment at a sarcoma reference centre is imperative. In the head and neck, the treatment for most bone sarcomas is neoadjuvant chemotherapy followed by compartmental resection. The interim tumour response to neoadjuvant chemotherapy is evaluated by PET CT and MRI. Heavy-particle therapy (proton beam) in combination with surgery is increasingly being used to treat otherwise unresectable disease, particularly in children. For soft tissue sarcomas of the head and neck, treatment is complex and depends on grade. Surgery is the principle mode of treatment in low-grade tumours that are amenable to resection. High-grade tumours can be treated with neoadjuvant chemotherapy followed by surgery and radiotherapy. In such cases, the response to the chemotherapy might be used as a guide of potential biological aggressiveness, and has an impact on the planning of the operation and the type and extent of radiotherapy. As a general rule, radiotherapy is reserved for high-grade, advanced soft-tissue sarcomas of the head and neck. Those of bone are radioresistant, and radiotherapy is only administered for palliative purposes when no surgical option exists, an exception being Ewing sarcoma. The role of proton beam therapy is promising, but to our knowledge no long-term data currently exist. The survival advantage of innate immune-modulation remains uncertain for disease in the head and neck.

RESUMEN

Although tobacco use is declining in several countries including India (dropping from 35% in 2009-10 to 29% 2016-17 among adults)-it still poses a huge burden on India, as the world's second largest consumer of tobacco products. In Bihar state, with a prevalence of 25%, the Bihar School Teachers Study (BSTS) successfully enlisted teachers as role models for encouraging quitting and changing social norms pertaining to tobacco. The study used a mixed-methods approach to identify factors associated with teachers' quitting. Qualitative data were collected through focus groups with teachers and school principals. Quantitative data were collected through a written survey administered to school personnel post-intervention. Key findings from focus groups were that teachers and principals quit using tobacco and promoted cessation because they wanted to model positive behaviors; specific information about tobacco's harms aided cessation; and the BSTS intervention facilitated a school environment that supported quitting. Survey results indicated teachers who reported knowing people who quit using tobacco in the prior year were far more likely to quit as were teachers who reported that their school's tobacco policy was completely enforced. The combination of qualitative and quantitative data yielded important insights with strong implications for future interventions.

RESUMEN

Rotavirus A (RVA) infections are known to retard the piglets' growth and minimize the profit to the pig farming community. Between August 2014 and July 2017, in a cross-sectional study, we surveyed 13 organized pig farms located in the eight states of India representing northern, north-eastern and southern regions, to identify the risk factors associated with RVA infection in pre- and post-weaning piglets. Faecal samples (n = 411) comprising of non-diarrhoeic (n = 320) and diarrhoeic (n = 91) were collected and screened for RVA infection using VP6 gene-based RT-PCR. RVA positivity of 52.5% (168/320) in non-diarrhoeic and 59.3% (54/91) in diarrhoeic piglets was noticed. Further, 53.3% (120/225) and 54.8% (102/186) of the samples from pre- and post-weaned samples were positive for RVA, respectively. To note, no statistically significant association was noticed between RVA infection, health and weaning status. Additionally, a questionnaire-based survey was conducted to identify the risk factors for RVA infections in piglets. The analysis revealed that good ventilation (OR 0.2, 95% CI 0.15-0.39), use of deep well water (OR 0.2, 95% CI 0.13-0.43) and feeding of commercial feed (OR 0.3, 95% CI 0.18-0.41) were associated with reduced risk of RVA infection compared with poor ventilation, use of shallow well water and feeding of own milled feed, respectively. Contrarily, mixed farms (OR 2.1, 95% CI 1.26-3.37), use of heater or cooler (OR 5.9, 95% CI 3.74-9.30), sheds in different elevation (OR 2.5, 95% CI 1.20-5.01) and weekly and occasional use of disinfectant for surface cleaning (OR 1.8, 95% CI 1.12-2.96) were associated with higher RVA infection. Mitigating the risk factors might help in better health management of piglets and increase the economic return to pig farming community in the country.

RESUMEN

BACKGROUND: The association of smokeless tobacco (SLT) with stroke has been dealt with in only a few reviews. The present meta-analysis aims to present the updated comprehensive summary risk of stroke in adult SLT users along with sub group analysis. METHODS: A systematic literature search for articles evaluating risk of stroke in SLT users was conducted. The study characteristics and risk estimates were extracted independently by two authors (RG and SG). Random-effect model was used to estimate the summary relative risks. RESULTS: The overall risk of stroke in SLT users was found to be significantly higher (1.17, 95% CI 1.04­1.30) compared to non-users, especially for users in Southeast Asian region. The results remained unchanged even after strict adjustment for smoking (1.18, 95% CI 1.04­1.32). SLT users had 1.34 times or 13.4% higher risk of fatal stroke, though risk of nonfatal stroke was not enhanced. Significantly higher risk of stroke was seen in users of chewing tobacco (1.35, 95% CI 1.20­1.50) in comparison to non-chewers. Gender-based analysis showed enhanced risk of fatal stroke in both male and female users. SLT-attributable fraction of fatal stroke was highest for India at 14.8%. CONCLUSION: The significant higher risk of stroke with SLT use, even after adjustment for smoking, emphasizes the imperative need to include SLT cessation advice for control and prevention of stroke.

RESUMEN

A cross-sectional study was conducted from 2014 to 2017 in 13 organised pig farms located in eight states of India (Northern, North-Eastern and Southern regions) to identify the risk factors, pathotype and antimicrobial resistance of Escherichia coli associated with pre- and post-weaning piglet diarrhoea. The data collected through questionnaire survey were used to identify the risk factors by univariable analysis, in which weaning status, season, altitude, ventilation in the shed, use of heater/cooler for temperature control in the sheds, feed type, water source, and use of disinfectant, were the potential risk factors. In logistic regression model, weaning and source of water were the significant risk factors. The piglet diarrhoea prevalence was almost similar across the regions. Of the 909 faecal samples collected (North - 310, North-East - 194 and South - 405) for isolation of E. coli, pathotyping and antibiotic screening, 531 E. coli were isolated in MacConkey agar added with cefotaxime, where 345 isolates were extended spectrum ß-lactamase (ESBL) producers and were positive for blaCTX-M-1 (n = 147), bla TEM (n = 151), qnrA (n = 98), qnrB (n = 116), qnrS (n = 53), tetA (n = 46), tetB (n = 48) and sul1 (n = 54) genes. Multiple antibiotic resistance (MAR) index revealed that 14 (2.64%) isolates had MAR index of 1. On the virulence screening of E. coli, 174 isolates harboured alone or combination of Stx1, Stx2, eaeA, hlyA genes. The isolates from diarrhoeic and post-weaning samples harboured higher number of virulence genes than non-diarrhoeic and pre-weaning. Alleviating the risk factors might reduce the piglet diarrhoea cases. The presence of multidrug-resistant and ESBL-producing pathogenic E. coli in piglets appears a public health concern.
