RESUMO
MOTIVATION: Promoter-centered chromatin interactions, which include promoter-enhancer (PE) and promoter-promoter (PP) interactions, are important to decipher gene regulation and disease mechanisms. The development of next-generation sequencing technologies such as promoter capture Hi-C (pcHi-C) leads to the discovery of promoter-centered chromatin interactions. However, pcHi-C experiments are expensive and thus may be unavailable for tissues/cell types of interest. In addition, these experiments may be underpowered due to insufficient sequencing depth or various artifacts, which results in a limited finding of interactions. Most existing computational methods for predicting chromatin interactions are based on in situ Hi-C and can detect chromatin interactions across the entire genome. However, they may not be optimal for predicting promoter-centered chromatin interactions. RESULTS: We develop a supervised multi-modal deep learning model, which utilizes a comprehensive set of features such as genomic sequence, epigenetic signal, anchor distance, evolutionary features and DNA structural features to predict tissue/cell type-specific PE and PP interactions. We further extend the deep learning model in a multi-task learning and a transfer learning framework and demonstrate that the proposed approach outperforms state-of-the-art deep learning methods. Moreover, the proposed approach can achieve comparable prediction performance using predefined biologically relevant tissues/cell types compared to using all tissues/cell types in the pretraining especially for predicting PE interactions. The prediction performance can be further improved by using computationally inferred biologically relevant tissues/cell types in the pretraining, which are defined based on the common genes in the proximity of two anchors in the chromatin interactions.

MOTIVATION: Small insertion and deletion (sindel) of human genome has an important implication for human disease. One important mechanism for non-coding sindel (nc-sindel) to have an impact on human diseases and phenotypes is through the regulation of gene expression. Nevertheless, current sequencing experiments may lack statistical power and resolution to pinpoint the functional sindel due to lower minor allele frequency or small effect size. As an alternative strategy, a supervised machine learning method can identify the otherwise masked functional sindels by predicting their regulatory potential directly. However, computational methods for annotating and predicting the regulatory sindels, especially in the non-coding regions, are underdeveloped. RESULTS: By leveraging labeled nc-sindels identified by cis-expression quantitative trait loci analyses across 44 tissues in Genotype-Tissue Expression (GTEx), and a compilation of both generic functional annotations and large-scale epigenomic profiles, we develop TIssue-specific Variant Annotation for Non-coding indel (TIVAN-indel), which is a supervised computational framework for predicting non-coding regulatory sindels. As a result, we demonstrate that TIVAN-indel achieves the best prediction performance in both with-tissue prediction and cross-tissue prediction. As an independent evaluation, we train TIVAN-indel from the 'Whole Blood' tissue in GTEx and test the model using 15 immune cell types from an independent study named Database of Immune Cell Expression. Lastly, we perform an enrichment analysis for both true and predicted sindels in key regulatory regions such as chromatin interactions, open chromatin regions and histone modification sites, and find biologically meaningful enrichment patterns.

The need to develop wearable devices for personal health monitoring, diagnostics, and therapy has inspired the production of innovative on-demand, customizable technologies. Several of these technologies enable printing of raw electronic materials directly onto biological organs and tissues. However, few of them have been thoroughly investigated for biocompatibility of the raw materials on the cellular, tissue, and organ levels or with different cell types. In addition, highly accurate multiday in vivo monitoring using such on-demand, in situ fabricated devices has yet to be done. Presented herein is the first fully biocompatible, on-skin fabricated electronics for multiple cell types and tissues that can capture electrophysiological signals with high fidelity. While also demonstrating improved mechanical and electrical properties, the drawn-on-skin ink retains its properties under various writing conditions, which minimizes the variation in electrical performance. Furthermore, the drawn-on-skin ink shows excellent biocompatibility with cardiomyocytes, neurons, mice skin tissue, and human skin. The high signal-to-noise ratios of the electrophysiological signals recorded with the DoS sensor over multiple days demonstrate its potential for personalized, long-term, and accurate electrophysiological health monitoring.

Background The use of complementary and alternative medicine, particularly yoga is increasing in non-communicable diseases (NCDs). We assessed the overall awareness regarding yoga among patients and their opinion about it as an adjunct therapy for NCDs. Methods We included 384 patients attending the cardiology and neurology clinics at a tertiary care centre in northern India. A questionnaire was developed to assess the knowledge, attitude and practice of yoga as a therapy. Results Ninety per cent of patients were aware of yoga, mainly through print and electronic media. Of the surveyed patients, 22% practised yoga. Lack of time and knowledge were cited as the main reasons for non-practice among the non-practising patients (88%), of which 82% believed that yoga could be practised along with modern medicine. In addition, 61% were ready to accept treatment if offered at the surveyed tertiary care centre. Conclusions Adequate knowledge, awareness and attitude towards yoga appears to be present in contrast to the low practice among the patient population surveyed. If implemented in an integrated fashion, the patients were willing to accept yoga as an adjunct therapy for their cardiac and neurological disorders-an encouraging sign given the burden of NCDs in India.

The study reports the synthesis of fructo-oligosaccharide (FOS) from sucrose using invertase derived from Saccharomyces cerevisiae. The reaction was conducted in a batch mode under free enzyme condition. Fructo-oligosaccharide formation was detected at a high sucrose concentration of over 200 g/L. The investigation was extended to study the effect of different parameters such as initial sucrose concentration (ISC), pH, and enzyme concentration. A maximum FOS yield of 10 % (dry basis) was observed using 525 g/L of ISC, with 6 U/mL of the enzyme, and pH 5.5 at 40 °C. 1-Kestose was the major product of among different forms of FOS. The FOS yield increased with an increase in sucrose concentration up to 525 g/L, beyond which it started to decrease. However, the maximum FOS yield was not affected by the increasing concentration of the enzyme beyond a certain level (2 U/mL). Furthermore, the activity of enzyme slightly increased with an increase in the pH up to 6, and thereafter it declined. Addition of glucose decreased the FOS yield because of enzyme inhibition. A five-step, ten-parameter model was developed, for which the simulation was performed in COPASI. The results predicted by the model were consistent with the experimental data.

INTRODUCTION: Functional Neurosurgery (FNS) is a non-invasive and highly efficacious neurosurgical subspecialty but lower middle-income countries (LMICs) are disadvantaged in terms of access and availability of FNS. Through this study we have tried to assess the availability, exposure, utilization, and perceived barriers to five major FNS modalities including deep brain stimulation (DBS), vagal nerve stimulation (VNS), stereotactic radiosurgery (SRS), MRI-guided focused ultrasound (MRgfUS) and percutaneous rhizotomy in LMICs. METHODOLOGY: We designed a survey using google forms while following the CHERRIES guidelines. Responses were collected from practicing neurosurgeons, neurosurgical fellows, and residents in LMICs. Statistical analysis was performed using SPSS software 26.0 RESULTS: A total of 100 responses were recorded of which 96â¯% were males. 68â¯% worked in an educational setup. Respondents had the most exposure to SRS (36â¯%) followed by DBS (28â¯%) while MRgFUS was the least exposed modality (4â¯%) (p<0.001). For all modalities except MRgFUS, majority of the respondents were 'Fairly confident' (p<0.001). No statistically significant association was observed in the availability of the modalities with the type of working setup. Majority of the respondents did not consider legal issues (p=0.003) and patient preferences (p=0.007) to be perceived barriers for any modality. Accessibility, affordability, Lack of training were not significant factors for any modality except DBS (52â¯%, p<0.001; 55â¯%, p<0.001 and 53â¯%, p=0.002 respectively) CONCLUSION: An integrated approach including international collaborations, traveling fellowships, novel policies must be adopted to enhance the reach of FNS to LMICs to share the extensive neurosurgical burden and to ease the neurosurgical decision making.
RESUMO
BACKGROUND: Medical students are actively involved in direct patient care during their training and subsequent medical practice, making them susceptible to acquiring blood-borne pathogens, including HBV. This study aimed to assess the occurrence of blood-borne infections and the Hepatitis B immunization status among medical students. Furthermore, it sought to identify gaps in risk assessment for blood-borne pathogens among medical students at a Medical College in New Delhi. METHODS: The study included 108 medical students who participated in a blood donation camp. Blood samples collected from these individuals underwent testing for blood-borne pathogens in accordance with standard screening protocols at the blood bank. The quantitative estimation was performed for anti-HBs IgG using ELISA. RESULTS: All 108 participants were pursuing their undergraduate or postgraduate medical degrees. All students tested negative for HBsAg and HIV markers and showed no reactivity to Syphilis and Malaria. However, one student tested positive for HCV. Two postgraduate students had a history of needlestick injuries. Eighty-one (75%) students had received Hepatitis B vaccination. Among the vaccinated students, 34 (41.97%) were immunized before the age of five years, 22 (27.16%) after the age of five years, while 25 (30.86%) couldn't recall the exact age of their Hepatitis B vaccination. Protective anti-HBs titer of anti-Hepatitis B antibodies (>10 mIU/ml) were detected in 48.15% (52/108) of students. CONCLUSIONS: Over 50% of medical students did not possess sufficient immunity against HBV infection, putting them at a heightened risk of acquiring HBV during their active participation in patient care in the near future. It is imperative to establish a policy for routine anti-HBs titer assessment and ensure easy access to Hepatitis B immunization for medical students, thereby enhancing their protection against this infectious agent.

BACKGROUND: Depression is a leading cause of disability and the conventional management has several limitations. Recent studies demonstrated the benefits of yoga in psychological disorders. AIMS: To evaluate the efficacy of the Integrated Yoga Module (IYM) to standard care with added yogic education on lifestyle modification (YELM) in patients with clinical depression. METHODS: A PROBE trial was conducted at a single tertiary care hospital in India. Adults aged 18 to 64 with clinical depression were randomized to either an IYM or an active control group using a computer-generated mixed block randomization sequence. Both groups received YELM in addition to standard care and the intervention group practiced IYM, for 8 weeks. The primary outcome was the reduction in depression symptoms assessed using the Beck Depression Inventory (BDI-II), and secondary outcomes involved self-compassion, brief resilience, positive and negative experiences, and quality of life, evaluated at 8 weeks. RESULTS: The mean ± SD age of participants was 32.2 ± 10.0 and 54.3% were females. The IYM group showed statistically significant improvements in BDI-II scores ß = -6.7 (95% CI [-10.8, -2.5]; p = .001), resilience ß = 0.4 (95% CI [0.02, 0.80]; p = .037), physical health domain of WHOQOL - BREF ß = 10.1 (95% CI [0.7, 19.5]; p = .035) and negative emotions (SPANE-N) ß = 2.8 (95% CI [0.1, 5.4]; p = .037). However, no significant differences were found in SCS-SF ß = -0.3 (95% CI [-0.7, 0.0]; p = .053). CONCLUSIONS: IYM as an adjunct is superior to conventional medical management in reducing symptoms and improving positive psychological resources in clinical depression.

Background: Diarrhea is a prevalent condition affecting millions worldwide. However, current standard diagnostic methods have many drawbacks. This review examines various non-invasive point-of-care (POC) tests and biomarkers aiding rapid diagnosis of diarrhea from different causes. Methods: PubMed, PubMed Central, ScienceDirect, Cochrane Library, and Google Scholar were searched from 2013 to present for relevant literature. Two reviewers independently assessed included studies' quality using the Critical Appraisal Skills Programme (CASP) checklist. Results: The search yielded 1453 studies, of which 39 were included after screening and applying eligibility criteria. Polymerase chain reaction (PCR) was the POC test in 25 studies, providing consistent sensitivity and specificity. For biomarkers, C-reactive protein (CRP), fecal calprotectin, and procalcitonin offered high sensitivity and specificity for conditions like acute pediatric diarrhea, microscopic colitis, and inflammatory diarrhea, respectively. Conclusion: PCR proved the ideal POC test for rapid diarrhea diagnosis, while the procalcitonin biomarker helps differentiate inflammatory from non-inflammatory diarrhea. Other reviewed tools also demonstrated promising diagnostic performance, though improvements in sensitivity, specificity, and usability are still needed.
RESUMO
The factors driving or preventing pathological expansion of tandem repeats remain largely unknown. Here, we assessed the FGF14 (GAA)·(TTC) repeat locus in 2,530 individuals by long-read and Sanger sequencing and identified a common 5'-flanking variant in 70.34% of alleles analyzed (3,463/4,923) that represents the phylogenetically ancestral allele and is present on all major haplotypes. This common sequence variation is present nearly exclusively on nonpathogenic alleles with fewer than 30 GAA-pure triplets and is associated with enhanced stability of the repeat locus upon intergenerational transmission and increased Fiber-seq chromatin accessibility.

The outbreak of COVID-19 has engulfed the entire world since the end of 2019, causing tremendous loss of lives. It has also taken a toll on the healthcare sector due to the inability to accurately predict the spread of disease as the arrangements for the essential supply of medical items largely depend on prior predictions. The objective of the study is to train a reliable model for predicting the spread of Coronavirus. The prediction capabilities of various powerful models such as the Autoregression Model (AR), Global Autoregression (GAR), Stacked-LSTM (Long Short-Term Memory), ARIMA (Autoregressive Integrated Moving Average), Facebook Prophet (FBProphet), and Residual Recurrent Neural Network (Res-RNN) were taken into consideration for predicting COVID-19 using the historical data of daily confirmed cases along with Twitter data. The COVID-19 prediction results attained from these models were not up to the mark. To enhance the prediction results, a novel model is proposed that utilizes the power of Res-RNN with some modifications. Gated Recurrent Unit (GRU) and LSTM units are also introduced in the model to handle the long-term dependencies. Neural Networks being data-hungry, a merged layer was added before the linear layer to combine tweet volume as additional features to reach data augmentation. The residual links are used to handle the overfitting problem. The proposed model RNN Convolutional Residual Network (RNNCON-Res) showcases dominating capability in country-level prediction 20 days ahead with respect to existing State-Of-The-Art (SOTA) methods. Sufficient experimentation was performed to analyze the prediction capability of different models. It was found that the proposed model RNNCON-Res has achieved 91% accuracy, which is better than all other existing models.

Universal quantum computation can be realised using both continuous-time and discrete-time quantum walks. We present a version based on single particle discrete-time quantum walk to realize multi-qubit computation tasks. The scalability of the scheme is demonstrated by using a set of walk operations on a closed lattice form to implement the universal set of quantum gates on multi-qubit system. We also present a set of experimentally realizable walk operations that can implement Grover's algorithm, quantum Fourier transformation and quantum phase estimation algorithms. An elementary implementation of error detection and correction is also presented. Analysis of space and time complexity of the scheme highlights the advantages of quantum walk based model for quantum computation on systems where implementation of quantum walk evolution operations is an inherent feature of the system.
RESUMO
BACKGROUND: Obesity is recognised as an important risk factor for obstructive sleep apnea (OSA), with obese individuals at a four times higher risk of being diagnosed with the syndrome. Treating obesity with lifestyle modification is associated with a reduction in the severity of obstructive sleep apnea. Yoga comprises lifestyle modification that includes asana (postures), pranayama (breathing techniques), dhyana (meditation) and guideline principles for healthy living (Yama and Niyama). There is a scarcity of data to evaluate the effect of yoga on OSA. This study was conducted to evaluate the efficacy of Yoga based lifestyle modification on OSA. METHODS: Consenting obese patients (BMI >23) diagnosed with obstructive sleep apnea (OSA) (AHI>5) on Polysomnography (PSG) were enrolled. Eligible patients were randomized into two groups. The control group received counselling for dietary modification (staple Indian) with regular exercise and the active intervention group received Yoga intervention as treatment (OSA module) in addition to similar dietary modification and regular exercise counselling. Polysomnography (PSG) was conducted at baseline and one year follow-up. All patients were evaluated at baseline, six months, and one year for compliance and anthropometric parameters. Additional assessment with Hamilton scales for depression and anxiety, SF-36, and the Pittsburgh sleep quality index was also conducted. RESULTS: A total of 37 eligible patients (19 in the control group and 18 in the yoga group) were recruited for the study. The age [45.73 ± 10.71 vs. 46.22 ± 9.39 years, p = 0.88] and gender [15(78.95%) vs. 12(66.67%), p = 0.48 (males)] distribution was similar in both groups. After adjusting for age and gender, the percentage reduction in weight between the two groups did not reach statistical significance at one year. There was no significant difference in mean AHI between the two groups at one year. However, the number of patients with more than 40% AHI reduction [2/19 (10.52%) vs 8/18 (44.44%), p = 0.02] was significantly higher in the yoga group. Additionally, within the groups, the mean AHI at one year was significantly reduced in the yoga group [51.2 ± 28.0 to 36.8 ± 21.0/hour, p = 0.003], while no significant change was found in the control group [47.2 ± 23 to 38.8 ± 19.9/hour, p = 0.08]. CONCLUSIONS: Lifestyle alteration using Yoga intervention and modification of staple Indian diet may be effective in reducing OSA severity among obese patients. CTRI NUMBER: CTRI/2017/05/008462.

MacroH2A has established tumour suppressive functions in melanoma and other cancers, but an unappreciated role in the tumour microenvironment. Using an autochthonous, immunocompetent mouse model of melanoma, we demonstrate that mice devoid of macroH2A variants exhibit increased tumour burden compared with wild-type counterparts. MacroH2A-deficient tumours accumulate immunosuppressive monocytes and are depleted of functional cytotoxic T cells, characteristics consistent with a compromised anti-tumour response. Single cell and spatial transcriptomics identify increased dedifferentiation along the neural crest lineage of the tumour compartment and increased frequency and activation of cancer-associated fibroblasts following macroH2A loss. Mechanistically, macroH2A-deficient cancer-associated fibroblasts display increased myeloid chemoattractant activity as a consequence of hyperinducible expression of inflammatory genes, which is enforced by increased chromatin looping of their promoters to enhancers that gain H3K27ac. In summary, we reveal a tumour suppressive role for macroH2A variants through the regulation of chromatin architecture in the tumour stroma with potential implications for human melanoma.

Rheumatic heart disease (RHD) is often considered as a disease of developing countries and India is the home of about 40% of RHD patients. Environment seems to play a major role in its causation. Since gene environment interactions can lead to alterations of various metabolic pathways, identification of altered metabolites can help in understanding the various pathways leading to RHD. Blood plasma samples from 51 RHD and 49 healthy controls were collected for the study. Untargeted metabolomics approach was used to identify the metabolites that are altered in RHD patients. Data showed 25 altered metabolites among RHD patients. These altered metabolites were those involved in Purine, Glutamine, Glutamate, Pyrimidine, Arginine, Proline and Linoleic metabolism. Thus, the present study illuminates metabolic alterations among RHD patients which can help in determining the potential therapeutic targets.

PURPOSE: Late-onset atrial fibrillation (LOAF) after valve surgery for degenerative mitral valve disease often with underlying mitral valve prolapse is a known phenomenon. However, there is no similar data for postoperative rheumatic heart disease (RHD) patients. We sought to assess the incidence and predictors of LOAF during postoperative follow-up in RHD patients. METHODS: This single-center retrospective case-control study included a total of 384 RHD patients with normal sinus rhythm (NSR) who underwent rheumatic valve surgery between 1st July 2008 and 30th June 2013. Patients detected with de novo persistent atrial fibrillation (AF) after 2 months of valve surgery were diagnosed as having LOAF. Presurgical demographic and echocardiographic parameters were compared between the LOAF and NSR groups to identify risk factors for LOAF. RESULTS: The incidence of de novo LOAF after rheumatic valve surgery was 9.63% at an average of 2.67 ± 1.32 years follow-up. Age ≥ 32 years [OR 2.4 (95% CI 1.2-5.1); P = 0.01] and left atrial (LA) size ≥ 51 mm [OR 5.9 (95% CI 2.8-12.4); P < 0.0001] were the most significant and independent predictors of LOAF. Moreover, significant mitral valve disease was associated with a higher risk of LOAF than significant aortic valve disease (P = 0.037). LA size ≥ 51 mm at surgery showed a fair discriminative power [AUC = 0.75; sensitivity = 68%, specificity = 70%] to identify patients at high risk for LOAF. CONCLUSIONS: Late-onset AF develops in almost a tenth of the RHD patients postoperatively following corrective valve surgery. Preoperative LA size can be used to identify patients at high risk for LOAF.

BACKGROUND: The present study aimed to evaluate the safety and prophylactic efficacy of add-on Comprehensive Ayurveda and mindfulness-based Yoga (CAY) regimen to standard care among HealthCare Workers (HCWs) against COVID-19. MATERIALS AND METHODS: This prospective single-blind (outcome assessor-blinded) RCT was conducted in tertiary care hospital in Delhi during July 2020-April 2021. HCWs of both sexes were randomized to add-on CAY intervention or control group. The primary outcomes were the incidence of confirmed COVID-19 positive cases and influenza-like illness events (ILI). Secondary outcomes were anxiety (GAD-7), depression (PHQ-9), and quality of life (SF-36) at the end of 12 weeks. RESULTS: Three hundred fifty-six participants (181 in intervention and 175 in the control group) were randomized. With the modified intention to treat approach, we analyzed 309 participants. The mean age for the intervention and control group was 39.3 ± 10.1 and 36.6 ± 10 years, respectively. Incidence of COVID-19 event was higher in control group compared to CAY group (16 of 164 [9.8%] vs. 11 of 145 [7.6%]; P = 0.50). The incidence of ILI events was also higher in the control group as compared to the CAY group (14 of 164 [8.5%] vs 9 of 145 [6.2%]). The health change domain of the SF-36 questionnaire showed statistically significant improvement in the CAY group as compared to the control group (P < 0.01). CONCLUSION: Incidence of COVID-19 and ILI events was lower in the CAY group compared with the contr ol group, though the difference is not statistically significant.

Background: Care of COVID-19 patients has been shown to affect the mental health of healthcare personnel (HCP), however, there is little data reflecting psychological health of HCP in India. Aims: The present study was undertaken to assess the prevalence of psychological outcomes and its association with various sociodemographic and occupational factors among the HCP in India. Methodology: A cross-sectional, online survey, using snowball sampling method was conducted between June 1, 2020, and June 22, 2020. The HCP working in COVID-19 designated hospitals across India were invited to participate. Patient Health Questionnaire-4 and 19-item stress-related questionnaire were used to evaluate symptoms of overall anxiety, depression, COVID-19 infection specific anxiety, exhaustion, and workload. Results: In this cross-sectional study with 2334 HCP from 27 states and 7 union territories of India; 17.9% of participants had depression, 18.7% had overall anxiety, 26.5% had exhaustion, 30.3% reported heavy workload, and 25.4% had COVID-19 infection-specific anxiety, respectively. The HCP working in states with higher caseload was a common risk factor for overall anxiety (odds ratio [OR], 1.7; P < 0.001), depression (OR, 1.6; P < 0.001), COVID-19 infection-specific anxiety (OR, 2.5; P < 0.001), exhaustion (OR, 3.1; P < 0.001), and heavy workload (OR, 2.6; P < 0.001). Nurses were more at risk for depression (OR, 2.2; P < 0.001), anxiety specific to COVID-19 infection (OR, 1.3; P = 0.034), and heavy workload (OR, 2.9; P < 0.001); while doctors were more at risk for overall anxiety (OR, 2.0; P = 0.001) and exhaustion (OR, 3.1; P < 0.001). Conclusions: Frontline workers, specifically nurses and doctors, and those working in states with high COVID-19 caseload are more at risk for adverse psychological outcomes. The relatively less prevalence compared with other countries, is perhaps a reflection of measures undertaken, including early lockdown, ensuring better all-round preparedness and social norms.
RESUMO
OBJECTIVES: This study aims to determine the impact of yoga as an adjunct to standard therapy versus standard therapy alone on the symptomatic burden in patients with recurrent vasovagal syncope (VVS). BACKGROUND: There is a significant reduction in the quality of life (QoL) of patients with recurrent VVS. Existing management therapies have been largely ineffective. Recent trials have demonstrated the efficacy of yoga in diseases with autonomic imbalance, suggesting its possible utility in VVS. METHODS: Patients with recurrent VVS were randomized to receive either a specialized yoga training program in addition to current guideline-based therapy (intervention arm, group 1) or current guideline-based therapy alone (control arm, group 2). The primary outcome was a composite of the number of episodes of syncope and presyncope at 12 months. Secondary outcomes included QoL assessment by World Health Organization Quality of Life Brief Field questionnaire (WHOQoL-BREF) scores and Syncope Functional Status Questionnaire scores at 12 months, head up tilt test, and heart rate variability at 6 weeks. RESULTS: A total of 55 patients underwent randomization. The mean number of syncopal or presyncopal events at 12 months was 0.7 ± 0.7 in the intervention arm compared to 2.52 ± 1.93 in the control arm (P < 0.01). In the intervention arm, 13 (43.3%) patients remained free of events versus 4 (16.0%) patients in the control arm (P = 0.02). QoL at 12 months showed significant improvement of all Syncope Functional Status Questionnaire scores and 2 domains of WHOQoL-BREF scores (P < 0.05). CONCLUSIONS: Yoga as adjunctive therapy is superior to standard therapy alone in reducing the symptomatic burden and improving QoL in patients with recurrent VVS.

Leptospirosis is considered as one of the most neglected zoonotic tropical diseases. Animals and humans acquire this infection through direct contact with contaminated urine or body fluids of infected animals. This prospective study was undertaken to know the proportion of leptospirosis in pediatric patients presented with acute febrile illness at the Post Graduate Department of Microbiology, King George's Medical University, Lucknow, Uttar Pradesh. Blood samples were collected over a period of one year from January to December 2018 from 70 pediatric patients aged up to 0-12 years presented with febrile illness for 3-14 days. Out of the 70 samples, 7 (10%) samples were found positive by IgM ELISA, 4 (5.7%) samples were positive by MAT and 3(4.3%) were found positive by PCR. Risk factors such as contact with infected animals and contaminated environment were highly associated with seropositivity of leptospirosis. Clinical symptoms such as fever, chills, myalgia, headache, abdominal pain and cough were significantly associated (pâ¯<â¯0.05) with the seropositivity of leptospirosis.
