Abstract
Anti-HCV reactive subjects were selected and relevant data was collected. Viral load and genotype were determined for all patients and were divided into low (<800,000 IU/mL) and high viral load (>800,000 IU/mL). Correlation of viral load with parameters like age, gender, risk factors and genotype etc. was determined by binomial regression. Higher viral load was noted with genotype 4, males and high risk groups like People Who Inject Drugs (PWIDs), blood transfusion before routine testing or frequent transfusion, Intravenous drug therapy and MTP by unregistered medical practitioners (P ≤ 0.5). Prevention and treatment strategies for HCV should be tailored around these areas.

Abstract
OBJECTIVE HR-HPV types 16 and 18 are responsible for pre-invasive and invasive lesions of the cervix, accounting for 70-80% of the total subtypes. The aim of this study was to investigate the prevalence of high-risk HPV subtypes 16 and 18 in self-collected vaginal samples using real-time micro-PCR and to study the acceptability of self-sampling. METHODS Eligible women (30-65 years) were screened from a semi-urban area of Uttarakhand (India) using self-sampling. High-risk HPV genotypes (16/31 and 18/45) were tested using real-time micro-PCR technique with results available in one hour. The positive results were validated by standard RT-PCR for high-risk HPV 16, 18, separately and for 12 other high-risk genotypes, combined. Ease of the procedure, level of comfort, and recommendation to other women were studied and the acceptability of self-sampling was analyzed using the Likert scale. RESULT Of 975 eligible women screened, 45 participants tested positive for HR-HPV (16/31,18/45) using real-time micro-PCR with a prevalence of 4.6%. Positive samples were further tested through routine RT-PCR and 60% were found to be HR-HPV 16 and 18 positive. For self-sampling, 96.72% (n=943) participants were 'very satisfied' and 94.15% (n=918) found self-sampling to be 'very comfortable' and 88.51% (n=863) stated that they will strongly recommend this test to other eligible women in the community. CONCLUSION We conclude that HR-HPV testing with limited genotyping showed a prevalence of 4.6%, 60% of these were HPV 16/18 positive. Point of care testing was feasible in the community and self-sampling was acceptable.

Abstract
India had faced three waves throughout the Coronavirus disease 2019 (COVID-19) pandemic, which had already impacted economic lives and affected the healthcare setting and infrastructure. The widespread impacts have inspired researchers to look for clinical indicators of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection prognosis. Cyclic threshold values have been used to correlate the viral load in COVID-19 patients and for viral transmission. In light of this correlation, a retrospective study was conducted to assess the trend of viral load in clinical and demographic profiles across the three waves. Data of a total of 11,125 COVID-19-positive patients were obtained, which had a Ct value of <35. We stratified Ct values as follows: under 25 (high viral load), 25-30 (moderate viral load), and over 30 (low viral load). We found a significantly high proportion of patients with high viral load during the second wave. A significantly high viral load across the symptomatic and vaccinated populations was found in all three waves, whereas a significantly high viral load across age groups was found only in the first wave. With the widespread availability of real-time PCR and the limited use of genomic surveillance, the Ct value and viral load could be a suitable tool for population-level monitoring and forecasting.

Abstract
Introduction This study attempts to generate preliminary data regarding post-COVID pulmonary fungal infections, namely, COVID-19-associated pulmonary aspergillosis (CAPA), COVID-19-associated pulmonary mucormycosis (CAPM), and mixed infections from the Himalayas and compares the micro-radio-clinical profile and outcomes of the affected patients. Materials and Methods A retrospective data analysis was conducted, where clinical profiles, microbiological and radiological reports, and outcomes of n = 16 patients of post-COVID pulmonary infections were compared. Results Of n = 16 patients, n = 7 had CAPA (n = 5 Aspergillus fumigatus, n = 1 Aspergillus flavus, and n = 1 Aspergillus niger), n = 5 CAPM (Rhizopus arrhizus), and n = 4 with mixed infections (n = 3 infected with Aspergillus fumigatus and Rhizopus spp. and n = 1 with Aspergillus flavus and Rhizopus arrhizus). Thick-walled cavitary lesions, air-fluid levels, and multiple centrilobular nodules were some of the common radiological findings reported among these patients. Conclusion The immuno-compromised state following COVID-19 infection and treatment might be responsible for the progression of regular exposure to the dense Himalayan vegetation into an invasive pulmonary fungal infection. Suspecting post-COVID pulmonary fungal infection is necessary for primary care physicians to ensure timely referral to higher centers. Mixed pulmonary fungal infections (coinfection with Aspergillus spp. and Rhizopus spp.) are also emerging as important sequelae of COVID-19.

Abstract
In the developing world, surgical-site infection (SSI)-associated pathogens are becoming more drug resistant implicating higher morbidity and management cost. Here, we tried to analyze the drug resistance pattern in our SSI-related isolates. Over 2 years, 191 clinically diagnosed SSIs (postbiliary tract and postgastrointestinal surgery) were included, and wound swabs were processed by conventional aerobic and anaerobic culture. Antibiotic minimum inhibitory concentration (MIC) was determined by the Epsilometer testing. Multidrug-resistant phenotypes were detected as per guidelines. The rate of SSI was 5.3% with Klebsiella, Staphylococcus, and Pseudomonas, growing predominantly, and no anaerobe detectable. About 19.4% of Staphylococcus aureus were methicillin-resistant S. aureus, and one-third of them had raised macrolide MIC. About 58.2% of Enterobacteriaceae isolates were extended-spectrum beta-lactamase producers. Isolates with raised meropenem MIC were observed. Antibiotic-resistant level in SSI cases is alarmingly high, and in susceptible strains, MIC is approaching the resistant level. Urgent corrective action is an emergency necessity.

Abstract
Hepatitis C virus (HCV) infection has varied clinical manifestations. Noninvasive tools can be useful to assess the severity of liver disease and the rate of spontaneous clearance. HCV infection was determined by antibody or RNA-based tests over a period of 18 months in 8030 samples from the Gastroenterology department. Noninvasive indicators (AST-to-platelet ratio index and fibrosis-4 index) were computed. HCV RNA load was compared with Child-Turcotte-Pugh score. Rate of spontaneous clearance was estimated. About 3.2% of patients were found to have HCV. Fatigue, anorexia, and nausea were the primary complaints followed by ascites and encephalopathy. Extrahepatic features such as autoimmune hepatitis and non-Hodgkin's lymphoma were rare. There was an absence of advanced liver cirrhosis (κ = 0.96) in the majority of cases. Spontaneous HCV resolution was seen in 10.37%.

Abstract
We report the first search for a nonstandard-model resonance decaying into τ pairs in e^{+}e^{-}→μ^{+}μ^{-}τ^{+}τ^{-} events in the 3.6-10 GeV/c^{2} mass range. We use a 62.8 fb^{-1} sample of e^{+}e^{-} collisions collected at a center-of-mass energy of 10.58 GeV by the Belle II experiment at the SuperKEKB collider. The analysis probes three different models predicting a spin-1 particle coupling only to the heavier lepton families, a Higgs-like spin-0 particle that couples preferentially to charged leptons (leptophilic scalar), and an axionlike particle, respectively. We observe no evidence for a signal and set exclusion limits at 90% confidence level on the product of cross section and branching fraction into τ pairs, ranging from 0.7 to 24 fb, and on the couplings of these processes. We obtain world-leading constraints on the couplings for the leptophilic scalar model for masses above 6.5 GeV/c^{2} and for the axionlike particle model over the entire mass range.

Abstract
We report the first measurement of the Michel parameter ξ^{'} in the τ^{-}→μ^{-}ν[over ¯]_{μ}ν_{τ} decay with a new method proposed just recently. The measurement is based on the reconstruction of the τ^{-}→μ^{-}ν[over ¯]_{μ}ν_{τ} events with subsequent muon decay in flight in the Belle central drift chamber. The analyzed data sample of 988 fb^{-1} collected by the Belle detector corresponds to approximately 912×10^{6} τ^{+}τ^{-} pairs. We measure ξ^{'}=0.22±0.94(stat)±0.42(syst), which is in agreement with the standard model prediction of ξ^{'}=1. Statistical uncertainty dominates in this study, being a limiting factor, while systematic uncertainty is well under control. Our analysis proved the practicability of this promising method and its prospects for further precise measurement in future experiments.

Abstract
It has been demonstrated that closed-loop diabetes management results in better glycemic control and greater compliance than open-loop diabetes management. Deep learning models have been used to implement different components of artifical pancreas. In this work, a novel deep learning model InsNET has been proposed to estimate the basal and bolus insulin level and insulin bolus in patients with type I diabetes utilizing subcutaneous insulin infusion pumps for closed loop diabetes management system. The proposed InsNET is formed with a Wide-Deep combination of LSTM and GRU layers. Additionally, physical activity level has been included as an input in comparison to previous models where only past glucose levels (CGM), meal intake (CHO) and past insulin dosage were used as inputs. The proposed model was tested on In-silico data, and it achieved a Mean Absolute Error (MAE) of 0.002 and Root Mean Squared Error (RMSE) of 0.007 for UVA/Padova Dataset and MAE of 0.001 and RMSE OF 0.003 for mGIPsim Dataset.Clinical relevance- Insulin dose determination is an important as aspect of artificial pancreas. This work describes a deep learning model to determine accurate basal and bolus insulin dosage.

Abstract
Leishmaniasis is a vector-borne parasitic disease affecting millions of people worldwide. However, in the last decade, the number of cases has been reduced from well-documented endemic parts, but sporadic cases have been reported widely from various non-endemic areas, especially from the southern Himalayan zone. This raises concerns about the emergence of new ecological niches. This warrants a critical evaluation of key factors causing this rapid spread and possibly indigenous transmission. This mini-review article is aimed to briefly address the parasite, the vector, and the environmental aspects in the transmission of leishmaniasis in these new foci against a background of worldwide endemic leishmaniasis with a special focus on the southern Himalayan zone. As the lack of knowledge about the causative parasites, vectors, reservoir hosts, atypical presentations, and their management make the problem serious and may lead to the emergence of public health issues. The present works also reviewed the existing information regarding clinical variations, diagnostic methods, treatment, its outcome, and ignite for further research in these aspects of the disease.

Abstract
Introduction The second wave of the coronavirus disease 2019 (COVID-19) pandemic in India, which started from April 2021, has been more severe and deadly than the first wave. The aim of this prospective study was to determine the possibility of other respiratory pathogens contributing towards the severity and hospitalization in the current second wave. Materials and methods Nasopharyngeal and oropharyngeal swab samples were collected and processed for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by reverse transcription polymerase chain reaction (RT-PCR). These samples were further processed for detection of co-infection in SARS CoV-2 patients by BioFire® Filmarray® 2.0 (bioMérieux, USA). Results We screened 77 COVID-19-positive patients admitted to All India Institute of Medical Sciences (AIIMS), Rishikesh and found cases of co-infections in five (6.49 %) patients. Conclusion Our finding suggests that co-infections had no or minimal role in augmenting the second wave of the COVID-19 pandemic in India, and the emergence of new variants may be the probable cause.

Abstract
BACKGROUND Urinary tract infection (UTI) is one of the most commonly encountered bacterial infections. Due to the misuse or excessive use of antibiotics, the upsurge of multidrug-resistance cases in UTIs has now become a global threat to public health. Exploring a newer or safer treatment using green synthesized nanoparticles (NPs) is another substitute for eliminating multidrug-resistant pathogens. METHODOLOGY Leaf extract of Syzygium cumini was used for green synthesis of gold NPs. Synthesis of Syzygium cumini gold nanoparticles (ScAu-NPs) was achieved by optimizing various reaction parameters. These ScAu-NPs were characterized through UV-visible spectroscopy, transmission electron microscope, Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction. ScAu-NPs were then processed for antibacterial activity against clinically isolated multidrug-resistant pathogens like Escherichia coli, Klebsiella pneumoniae, Proteus vulgaris, Acinetobacter baumannii, Staphylococcus aureus, and Enterococcus faecalis. RESULTS Characterization of NPs revealed that biosynthesized NPs were spherical in shape. FTIR spectroscopy showed the presence of phenolics and aromatic compounds. Biosynthesized NPs exhibit good antibacterial activity with a significant bacterial reduction seen against all bacterial isolates compared to the controls. CONCLUSION From the results of the present study, the formulation of biosynthesized ScAu-NPs can be utilized in drug development for eliminating infections caused by multidrug-resistant pathogens.

Abstract
BACKGROUND Convalescent plasma has been used to provide passive immunotherapy to patients with COVID-19 with a high level of safety. Very few efficacy studies were available, and due to COVID being a relatively new disease, its exact therapeutic role was unclear. This observational study on the impact of COVID convalescent plasma (CCP) on clinical outcomes attempts to evaluate the effectiveness of convalescent COVID-19 plasma therapy in the treatment of COVID-19 patients at the tertiary care center in the Uttarakhand state of India. METHODS CCP was collected by plasmapheresis/whole blood from willing COVIDrecovered donors who underwent pre-donation testing including ABO and RhD grouping, mandatory blood screening tests for HIV, HBV, HCV, syphilis and Malaria, Haemoglobin estimation and COVID IgG assay. Hospitalized patients with severe COVID-19 pneumonia who received these CCP units were followed up and the outcome (Recovery/death) was observed. RESULTS A total of 63 patients who received CCP were included in the study. Out of the total, 13 (20.7%) were females and 50 (79.3%) were males and their ages ranged from 24 to 80 years with a median age of 53 years. The period between the start of symptoms and hospitalization ranged from 1 to 14 days with an average duration of 4.7 days. Symptoms on presentation included Fever 53/63 (84.1%), Tachypnoea 60/63 (95.2%) and Cough 42/63 (66.7%). Among these patients, 22/63 (34.9%) were on non-invasive ventilation (NIV), 6/63 (9.5%) on non-rebreather mask (NRBM) and 32/63 (50.8%) were on Ventilator support. The infused convalescent plasma had a Mean IgG value of 57.3 AU with a range of (10-142 AU). A total of 37 (58.7%) patients were lost to COVID-19 infection and 26 (41.3%) were discharged from the hospital in a healthy state. CONCLUSION The use of convalescent plasma in addition to standard treatment in our study on patients with severe pneumonia due to COVID-19 did not demonstrate reduced mortality of COVID-19 patients amidst numerous variables. The results showed that the use of convalescent plasma as a treatment option in the present conditions needs a serious re-evaluation. Studies on a strictly defined recipient group and transfusion of CCP units, with adequate antibody titer and/or neutralization activity, must be analyzed for future works.

Abstract
BACKGROUND For the management of connective tissue disorders (CTDs), antinuclear antibody (ANA) testing is essential, both from diagnostic and prognostic points of view. Usually, patterns obtained by ANA-IIF testing correlates to specific autoantibodies as obtained from the test for ENA (by LIA/ELISA, etc.). But to apply these data from western studies, we may need validation in the local population like our subjects in sub-Himalayan (Garhwal region) area where CTDs are common. Also, suppose ANA-IFA pattern's correlation is reliably known in our population, it can minimize the cost of managing CTDs by limiting ENA testing, which is 10 times costlier than ANA-IIF. Hence, this study was undertaken to know the specific autoantibody targets (ENA by LIA) against ANA-IIF patterns in our local population. MATERIALS AND METHODS In this retrospective cross-sectional work, serum samples of CTDs were tested for ANA by IIF (Euroimmune AG) and ENA by LIA (Euroline ANA-3G) continuously for 36 months. The manufacturer's kit insert was followed, and results were analyzed applying appropriate statistical methods. RESULTS Major ANA-IIF patterns were found to be associated with specific autoantibodies, for example, Nuclear homogenous with dsDNA, nucleosomes, histones; speckled pattern with nRNP/Sm, Sm, SSA/Ro-52, SSB; nucleolar pattern with Scl-70, Pm-Scl 100 and centromere pattern with CENP-B. Anticytoplasmic (ACA) are found to be linked with some ANA negative (by IIF) samples, emphasizing the need for careful observation for ACA especially where ANA is not found. CONCLUSIONS In most subjects, specific ENA targets correlated well with ANA-IIF patterns, implying effective cost minimization in CTD management. Similar future prospective studies (with clinical data) can provide a database and reference for our population.

Abstract
Poster session 2, September 22, 2022, 12:30 PM - 1:30 PM
Objective
The study aims to generate preliminary data about post-COVID pulmonary fungal infections in the Himalayas and analyze patients’ micro-radio-clinical profiles and outcomes.
Methodology
We conducted a retrospective study at a tertiary care teaching hospital in the Himalayas to generate preliminary post-COVID pulmonary fungal infection data. Sputum, Endotracheal Tube (ET), and Bronchoalveolar lavage (BAL) samples of patients sent to the Mycology laboratory were subjected to KOH mount and aerobic inoculation on Sabouraud dextrose agar plates at 37°C. The patients’ symptoms, diagnosis, clinical-radiological profile, and outcome were collected from the hospital database.
Results
Among n = 16 cases of post-COVID pulmonary fungal infections aged 53 +/- 13.38 years, n = 7 (43.75%) had Pulmonary Aspergillosis (n = 5 A. fumigatus, n = 1 A. flavus, n = 1 A. niger), n = 5 (31.25%) had Pulmonary Mucormycosis (Rhizopus arrhizus), and n = 4 (25%) had mixed infection. In 2 of 4 mixed infection patients, R. arrhizus was identified on KOH microscopy and A. fumigatus on SDA Agar. Both A. fumigatus and R. arrhizus were identified on KOH Microscopy of the third patient, while only A. fumigatus was cultivated on his SDA Agar. Aspergillus flavus and R. arrhizus were isolated simultaneously from the sample of the last patient, but only R. arrhizus was identified on KOH Microscopy.
Clinical symptoms were similar among Pulmonary Aspergillosis and Mucormycosis patients, but hemoptysis was reported only among Pulmonary Aspergillosis patients. Pre-existing co-morbid end-organ damage, AKI, CKD, CLD, COPD, and CAD was more common among Pulmonary Mucormycosis patients and rare among Pulmonary Aspergillosis patients. Treatment requirements and clinical outcomes of patients infected with either mold were similar. The clinical profile of mixed infection patients was notably different from the others. All the patients were males, none complained of chest pain or expectoration, and none had a history of PTB, AKI, CKD, CLD, COPD, or CAD. Only 2 (50%) mixed infection patients needed supplemental high flow oxygen, unlike all (100%) patients diagnosed with single mold infection. None of the mixed infection patients required steroids. Moreover, none of the mixed infection patients died, unlike 60% mortality in cases of single-species infections.
On radiological investigation, n = 6 had typical thick-walled cavitary lesions with air-fluid levels and multiple centrilobular nodules giving a tree in bud appearance, of which n = 4 had bilateral lung involvement, and n = 2 had only one lung involved. n = 1 patient had a well-circumscribed lung abscess.
Conclusion
COVID patients from the Himalayas had a higher prevalence of invasive pulmonary fungal infections, probably due to the dense surrounding vegetation. The immuno-compromised state following COVID-19 infection/treatment might be responsible for the progression of regular exposure to invasive pulmonary infection.

Abstract
AbstractFasciolopsiasis, a food-borne intestinal parasitosis, occurs focally, and remains a significant public health problem in endemic areas. However, due to the wide spectrum of clinical presentation and unclear diagnosis or even misdiagnosis, it often goes unreported. The correlation between trematode infection and malnutrition is also often debated. We report a case of heavy infection of Fasciolopsis buski in a 4-year-old girl with severe acute malnutrition (SAM). The patient presented with a passage of many adult worms per stool following the consumption of some herbal concoction. A wet mount of the stool revealed ova of Fasciolopsis buski. She was treated successfully with praziquantel and food supplements. It raises the possibility of unidentified cases in this region and necessitates more extensive studies in the targeted population. This will also help raise awareness of fasciolopsiasis among clinicians, especially in vulnerable populations such as malnourished children.

Abstract
Closed-loop diabetes management has been shown to indicate improved glycaemic control and better compliance over open loop diabetes management. Currently, commercially available diabetes management devices rely on continuous glucose monitoring (CGM) sensors which monitor glucose levels from the interstitial fluid (ISF). As there exists a physiological delay between the blood glucose levels compared to the ISF glucose levels, it is crucial to predict or forecast glucose levels, in order to prevent hyperglycaemic events due to delayed insulin dosing. Accuracy of the forecast also needs to be optimum such that overdosing on insulin does not lead to hypoglycaemia. In this paper, we describe a novel Long Short Term Memory (LSTM) network which follows a wide and deep approach for different features to deliver an accurate glucose prediction output. It achieved a Mean Absolute Relative Difference (MARD) of 2.61 and Root Mean Squared Error (MSE) of 5.04. Clinical relevance- This work is relevant for closed-loop diabetes management devices, which are currently being used to manage Type 1 Diabetes (T1D).

Abstract
Pelvic exenteration is a surgery done to achieve margin negative resection in locally advanced rectal cancer infiltrating pelvic organs anterior to it. A retrospective observational study of patients undergoing pelvic exenteration for locally advanced rectal cancer was done at a single surgical unit of a tertiary care cancer centre. The period of study was from 1st January 2019 to 30th June 2021. A total of twelve patients underwent pelvic exenteration for locally advanced rectal cancer during the study period. The median duration of surgery was 310 min (range 250 to 380 min). The median duration of hospital stay was 14 days (range 12 to 30 days). Seven patients had documented postoperative complications, either major or minor, with a complication rate of 58.3%. Three patients required re-admission for complications. Two patients had COVID19 infection in the postoperative period but had uneventful recovery. Margin negative resection (R0) was achieved in eight patients (66.67%). Pelvic exenteration for locally advanced rectal cancer is a definitive surgery associated with a high morbidity rate.

Abstract
INTRODUCTION Subjects undergoing hemodialysis have enhanced vulnerability to hepatitis C virus (HCV) infection due to invasive procedures and poor infection control practices. Early detection and treatment are essential to prevent cross-infection and mortality/morbidity. However, common use anti-HCV antibody tests lack the necessary accuracy, and alternative tests (e.g. core antigen detection kits) which are available need to be examined as a viable alternative. METHOD A total of 270 continuous serum samples were collected from patients undergoing dialysis within 15 months of study period. Sequentially, multiple tests were performed - immunochromatography-based rapid test, third-generation ELISA i.e. (anti-HCV antibody detection), fourth-generation ELISA (HCV antigen-antibody combined detection assay), and HCV RNA quantitative real time polymerase chain reaction (qPCR) assay. Diagnostic parameters of serological kits were compared in terms of sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), accuracy, and so on. Statistical Package for the Social Sciences was used. RESULTS HCV-combined core antigen-antibody assays performed better than other serological assays in reference to the gold standard HCV RNA. This fourth-generation assay yielded a Kappa value of 0.947 compared with the value of 0.747 and 0.619 for anti-HCV ELISA and rapid detection test. Other parameters such as sensitivity, specificity, PPV, NPV, and so on were also better for fourth-generation ELISA compared with third-generation ELISA and other serological assays. HCV RNA was negative in 7.3% of anti-HCV-positive patients and was detected in 11.4% of anti-HCV ELISA-negative patients. In about 1.6% of HCV RNA-positive cases, fourth-generation ELISA was negative and had low HCV viral load (650 IU/ml and below). Fourth generation ELISA detected additional 7.4% HCV positive cases (compared to third generation kits) and upon cost effective analyis, additional cost to be bear for the better detection (by fourth generation kit) was found to be only INR 27 per 1% increased case detection. CONCLUSION In resource scant setup, screening and follow-up of patients undergoing hemodialysis can be performed by fourth-generation HCV ELISA (antigen-antibody combined assay) instead of the current practice of anti-HCV antibody ELISA. Better yield in detection rate will compensate for slight addition to costs.

Abstract
Atypical agents such as Mycoplasma, Legionella, Chlamydia species, and Coxiella burnetii (Q-fever agent) are responsible for some adult community-acquired pneumonia (CAP). Insufficient studies on this topic can be blamed for the failure to include atypical pathogens in empirical management. We followed adult CAP cases for two years, and samples (respiratory and serum) were tested by culture, ELISA (IgM, IgG, and IgA), and PCR. A risk factor analysis was performed. Overall in 21.3% adult CAP patients, atypical agents found were Mycoplasma pneumoniae (51.5%), Legionella pneumophila (28.8%), and Chlamydophila pneumoniae (19.7%). However, amongst patients <60 years of age and in the summer season, the proportion of atypical agents increased significantly. There is thus a need to re-examine empirical antibiotic regimes.

Abstract
Introduction Toxoplasma gondii (TG), rubella virus (RV), cytomegalovirus (CMV), and herpes simplex virus type 1 and 2 (HSV 1 and 2) cause mild maternal morbidity but have serious fetal consequences. The prevalence of these infections varies widely by country and population subgroup, and the paucity of data from the hilly state of Uttarakhand prompted us to undertake this study on their seroprevalence and association with potential risk factors. Methods Serum samples received from pregnant women attending the antenatal clinic of All India Institute of Medical Sciences, Rishikesh, between January 2016 to December 2019 were tested for TG-, RV-, CMV, and HSV-specific IgM and IgG by capture enzyme-linked immunoassay (ELISA). The data were then analyzed to determine the seroprevalence of the major ToRCH infections (toxoplasmosis, other (syphilis, varicella-zoster, parvovirus B19), rubella, cytomegalovirus, and herpes), and Fisher’s exact test was applied to check association with potential risk factors. Results Out of 165 pregnant women who were screened for the four major ToRCH pathogens, overall seroprevalence was 41.2% for TG (IgM=13.3%; IgG=38.2%), 80.0% for RV (IgM=3.0%; IgG=80.0%), 61.8% for CMV (IgM=1.8%; IgG=61.8%), and 42.4% for HSV (IgM=4.3%; IgG=40.6). TG was significantly associated with increasing maternal age (p-value=0.007). The seropositivity of RV was maximum in the drier and windy months of January-March (p-value=0.004), while that of TG in the warmer months of April-June (p-value=0.03). HSV prevalence was comparatively more common in Muslim women (p-value=0.05). Women presenting with bad obstetric history (BOH) and multiparous women were at higher risk for TG-RV-HSV and TG-RV-CMV, respectively. Conclusion Considering the high prevalence and risk of ToRCH infections in this region, we suggest disease-specific screening based on maternal history. Recognition of the burden of ToRCH infections in pregnant women is vital in clinicians’ decisions and implementing control measures.

Abstract
This critical narrative review is intended to emphasize the comprehensive ecological issues related to the evolution of the novel coronavirus, the environmental factors associated with the disease progress, and the impact the pandemic is having on the environment. Approximately 60% of the emerging infectious disease of the last century (including deadly viruses like HIV, Ebola, Influenza, coronavirus strains like SARS, MERS) are linked to zoonotic spillover. Therefore, to escape the emergence of newer cross-species infections, proper precautionary measures should be taken. Every country has specific rules to deal with the biomedical waste produced in hospitals. But the COVID-19 pandemic has posed a unique global challenge due to the overwhelming amount of biomedical waste generated from dedicated COVID hospitals, diagnostic facilities, quarantine centers, and home quarantine facilities. Moreover, inappropriate disposal of masks by the general public may contaminate the environment turning it into a potential health hazard. Therefore, strict adherence to Biomedical Waste Management Guidelines for proper disposal of masks and other medical waste by all concerned is a must. Lockdown has brought about tremendous improvement in conditions of the world’s atmosphere, hydrosphere, and biosphere. Dramatic improvement in air quality index, decrease in water, and noise pollution are some of the positive aspects of lockdown. However, these effects are temporary. But these teach an important lesson to the world to take some permanent measures to bring down greenhouse gases and other toxic emissions. Some harmful effects of lockdown are illegal deforestation, wildlife trafficking, encroachment of reserved areas etc.

Abstract
PURPOSE Disease pandemics are known to cause psychological distress. The ensuing mental health issues are not only restricted to the patients and their relatives/friends but affect the healthcare workers (HCWs) as well. Our study aims to assess these psychological trends during the COVID-19 pandemic between the two most affected population groups, that is, patients and frontline healthcare workers. PATIENTS AND METHODS A survey questionnaire, including scales to assess fear, anxiety, stress, depression - PSS 10, and DASS 21, was distributed and sent to all COVID-19 suspected/confirmed individuals and healthcare workers at a tertiary care center along with a second visit after 14 days of answering the first questionnaire and this continued as follow-up. Data were analyzed with the SPSS version 23 using various tests of significance. RESULTS In the community, COVID-19 patients in the age group 41-50 with respiratory tract symptoms and those who were home isolated/quarantined experienced a greater tendency of mental health problems. Healthcare workers posted in COVID-19 designated areas of the hospital displayed higher levels of stress, anxiety, and depression. CONCLUSION The high degree of uncertainty associated with novel pathogens has a profound effect on the psychological state of suspected/confirmed cases as well as healthcare workers. Within the community, individuals suspected of having COVID-19 display a significant mental health burden, while HCWs also experience an unprecedented amount of stress, anxiety, depression and fear during such enduring situations.

Abstract
Inguinal lymph nodal dissection is notoriously associated with high morbidity. Various risk factors and technical modifications have been described in the past to overcome complications like lymphedema, wound breakdown, and infection which adversely affect the postoperative outcome and quality of life of the patient. This is a retrospective observational study from 1 January 2016 to 31 December 2019 of patients who underwent inguinal/ilio-inguinal block dissection for malignancy. Lymphedema was the most frequent morbidity seen (24%). The mean hospital stay of patients following surgery was 9.7 days (range 4 to 28 days). The inguinal drain was removed on a mean of 17.7 days (range 4 to 21 days), while mean iliac drain removal time was 11.7 days (range 4 to 21 days).

Abstract
The objective of this study was to compare Reverse Hybridisation Assay with conventional sequencing for determination of Hepatitis C Virus Genotype and Subtypes. Anti-HCV antibody was determined followed by HCV RNA extraction which was used for (1) viral load determination (2) qualitative real-time PCR RHA for genotyping and (3) conventional sequencing. Compared to conventional sequencing, accuracy of RHA results was 96.55% for determination of genotype (κ = 0.93) and 89.66% for subtype (κ = 0.85). Sensitivity, specificity, negative predictive value (NPV) and positive predictive value (PPV) of the qualitative PCR were 82.29%, 100%, 44.44% and 100% respectively with an accuracy of 86.84%. RHA is a less time consuming and cheaper method for determination of HCV genotype and subtype yet results must be interpreted with caution and quality control monitoring should be strictly followed to ensure validity.

Abstract
Background
Antineutrophil cytoplasmic antibodies (ANCA) are important biomarkers in the diagnosis of ANCA-associated vasculitis, and indirect immunofluorescence (IIF) had been the method of choice for its detection from the very beginning. However, international consensus on ANCA testing (2017) advocates the use of high-quality immunoassays as the primary screening method. The purpose of this study was to evaluate the diagnostic performance of enzyme-linked immunosorbent assay (ELISA) compared to IIF in detecting ANCA.
Methods
One-hundred eighty-nine serum samples of suspected or known cases of systemic vasculitis were screened for ANCA by IIF and proteinase-3- and myeloperoxidase-ELISA. In IIF, positive results were further divided into cytoplasmic pattern of ANCA and perinuclear pattern of ANCA, depending upon the pattern of fluorescence. McNemar’s chi-squared test was applied to check the equality of proportions of positive results, and Kappa statistics was used to measure the agreement between the two methods. Diagnostic performance of ELISA was evaluated taking IIF as reference.
Results
IIF detected ANCA in 17.5% cases and ELISA detected it in 11.6% cases. A good agreement between the overall performance of ELISA and IIF was observed (
K
-value: 6.8,
p
-value: < 001). However, a significant difference in the proportion of positive results by the two methods was observed in McNemar’s test (two-sided
p
-value: 0.007). Taking IIF as standard, ELISA showed 60.6% sensitivity, 98.7% specificity, and predictive value of positive and negative results of 90.9 and 92.2%, respectively.
Conclusion
The new generation antigen-specific ELISAs had high specificity but the chances of missing cases in primary screening due to the low sensitivity and high false negativity (39.4%) need to be dealt with.

Abstract
Background and Aim Postoperative pancreatic fistula (POPF) is an important cause of major morbidity and mortality after pancreaticoduodenectomy. We intend to estimate the incidence and study the risk factors and outcomes of patients who developed this dreaded complication. Methods This is a retrospective observational study. We included all patients who underwent pancreaticoduodenectomy at a specialized surgical unit of a single tertiary care cancer center in Northeast India. The period of study was from 23 April 2012 to 27 December 2019. The 2016 update on the definition of POPF by the International Study Group for Pancreatic Fistula was used to define the complication. Chi‐square test and Fischer's exact test were applied to categorical variables. t‐test was used to quantify mean difference among continuous variables. P value <0.05 was considered statistically significant at 95% confidence interval. Results A total of 59 patients underwent pancreaticoduodenectomy during the study period with almost equal distribution among males and females (29 and 30 patients respectively). The mean age of the patients was 54.0 years (range 20–72). Grade A, B, and C pancreatic fistulas were seen in five (8.5%), three (5.1%), and two (3.4%) patients, respectively. Preoperative hyperbilirubinemia, pancreatic duct size ≤3 mm, hypoalbuminemia, preoperative biliary decompression, and prolonged duration of surgery were identified as risk factors for POPF. POPF also resulted in increased 90‐day mortality (20%). Conclusion POPF remains a potentially life‐threatening complication of pancreaticoduodenectomies. The knowledge and management of modifiable risk factors for this condition may help in mitigating this problem.

Abstract
Purpose: To assess and compare the diagnostic accuracy of the GenBody COVID-19 Antigen kit (GenBody Inc., Cheonan, South Korea) available in the market with the gold standard reverse transcription-polymerase chain reaction (RT-PCR) assay to detect severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Methods: Nasopharyngeal and oropharyngeal swabs were collected from suspected coronavirus disease 2019 (COVID-19) patients and tested by RT-PCR and GenBody Rapid antigen kit. Performance characteristic of the antigen kit was calculated. Results: We tested nasopharyngeal swabs and oropharyngeal swabs (n=240). Amongst the 102 positive RT-PCR samples, the rapid antigen test detected 36 as positive, showing an overall sensitivity of 35.3%. All the samples detected positive with the antigen rapid test were also detected positive by RT-PCR. Conclusion: The performance of the rapid antigen kit was good with respect to high viral load samples, whereas those with lower levels were missed. Unfortunately, the overall low sensitivity of the antigen kit does not allow using it alone as the frontline testing kit for COVID-19 diagnosis.

Abstract
From March to June 2021, India experienced a deadly second wave of COVID-19, with an increased number of post-vaccination breakthrough infections reported across the country. To understand the possible reason for these breakthroughs, we collected 677 clinical samples (throat swab/nasal swabs) of individuals from 17 states/Union Territories of the country who had received two doses (n = 592) and one dose (n = 85) of vaccines and tested positive for COVID-19. These cases were telephonically interviewed and clinical data were analyzed. A total of 511 SARS-CoV-2 genomes were recovered with genome coverage of higher than 98% from both groups. Analysis of both groups determined that 86.69% (n = 443) of them belonged to the Delta variant, along with Alpha, Kappa, Delta AY.1, and Delta AY.2. The Delta variant clustered into four distinct sub-lineages. Sub-lineage I had mutations in ORF1ab A1306S, P2046L, P2287S, V2930L, T3255I, T3446A, G5063S, P5401L, and A6319V, and in N G215C; Sub-lineage II had mutations in ORF1ab P309L, A3209V, V3718A, G5063S, P5401L, and ORF7a L116F; Sub-lineage III had mutations in ORF1ab A3209V, V3718A, T3750I, G5063S, and P5401L and in spike A222V; Sub-lineage IV had mutations in ORF1ab P309L, D2980N, and F3138S and spike K77T. This study indicates that majority of the breakthrough COVID-19 clinical cases were infected with the Delta variant, and only 9.8% cases required hospitalization, while fatality was observed in only 0.4% cases. This clearly suggests that the vaccination does provide reduction in hospital admission and mortality.

Abstract
Background: Empirical antibiotic therapy is the mainstay of management of adult community-acquired pneumonia (CAP) globally. Knowledge of prevalent pathogen (bacterial) profile and drug susceptibility pattern is very essential for appropriate management of CAP cases, which again calls for regular update of pathogen profile in a given locality. This study was to identify the bacterial etiology of CAP cases and their antibiotic susceptibility pattern. Methods: This cross-sectional study was done on adult CAP patients from medicine, respiratory medicine, and intensive care unit area in our tertiary care hospital between May 1, 2015, and October 30, 2016. Subjects were enrolled continuously, and expectorated sputum, bronchoalveolar lavage fluid, and blood culture were performed. Urine antigen test was done for Streptococcus pneumoniae and Legionella pneumophila. Three types of ELISA (IgM, IgG, and IgA) were performed for atypical agents (Mycoplasma, Chlamydia, and Legionella) of CAP. Isolates obtained from culture of Sputum/BAL/Blood were further processed for antibiotic susceptibility testing - by disc diffusion as well as E-test method (latter for MIC i.e. minimum inhibitory concentration, determination). Results: About 574 subjects were included, and in 266 (46.3%) cases, bacterial pathogen could be detected. Klebsiella pneumoniae (33.6%) and S. pneumoniae (32.9%) were the predominant agents identified. Atypical agents (Mycoplasma, Legionella, and Chlamydia) were at 15.1%. A high proportion of pneumococci isolates were multidrug resistant (52.6%). Resistance to beta-lactams, macrolide, and other agents was on the higher side, but fluoroquinolones were found to be less resistant (15.8%–21.1%). Extended-spectrum beta-lactamase (among Klebsiella isolates) and methicillin-resistant Staphylococcus aureus were also detected. Conclusion: A moderate-to-high degree of drug-resistant in adult CAP was evident, which is detrimental in effective empirical management of such cases. Urgent implementation of antibiotic stewardship scheme is the need of the hour.

Abstract
The knowledge, attitude, and practice (KAP) of healthcare workers (HCW) toward the COVID-19 pandemic influence their preparedness to accept the preventative measures. This study investigates KAP toward COVID-19 among the HCWs working in two designated COVID hospitals. It was a cross-sectional study. The overall KAP scores were calculated, and the difference in mean scores among various demographic and other variables was tested using t-test and one-way ANOVA. The participants were knowledgeable about transmission modes and disease symptoms and were aware of the preventive measures like hand sanitisations for 96% and 91% for wearing masks. Among the knowledgeable group, 87% were aware of the control measures of COVID-19 infection like isolation and treatment of the infected; quarantine of their close contacts; and 92% had the acquaintance about the avoidance of public transport and crowded places as a safety measure. The HCWs also showed a positive attitude toward keeping distance and staying at home (81.13% strongly agreed) and regularly washing hands (agreed 91%). The mean knowledge, attitude, and practice scores of the study participants were 19.67(±1.85), 27.95(1.81) and 4.61(0.51), respectively. Nurses were found to have significantly better knowledge, attitude, and practice toward COVID-19 than laboratory technicians and pharmacists. HCWs having higher education levels were also found to have better knowledge about COVID-19. The majority of the HCWs who participated in the study also strongly agreed that the referred hospitals are well prepared for infection prevention and control (IPC). Better knowledge, attitude and practices toward COVID-19 may considerably decrease the risk of getting the disease.

Abstract
Nucleotide-binding oligomerization domain NOD-like receptors (NLRs) are conserved cytosolic pattern recognition receptors (PRRs) that track the intracellular milieu for the existence of infection, disease-causing microbes, as well as metabolic distresses. The NLRP3 inflammasome agglomerates are consequent to sensing a wide spectrum of pathogen-associated molecular patterns (PAMPs) and danger-associated molecular patterns (DAMPs). Certain members of the NLR family have been documented to lump into multimolecular conglomerates called inflammasomes, which are inherently linked to stimulation of the cysteine protease caspase-1. Following activation, caspase-1 severs the proinflammatory cytokines interleukin (IL)-1β and IL-18 to their biologically active forms, with consequent commencement of caspase-1-associated pyroptosis. This type of cell death by pyroptosis epitomizes a leading pathway of inflammation. Accumulating scientific documentation has recorded overstimulation of NLRP3 (NOD-like receptor protein 3) inflammasome involvement in a wide array of inflammatory conditions. IL-1β is an archetypic inflammatory cytokine implicated in multiple types of inflammatory maladies. Approaches to impede IL-1β’s actions are possible, and their therapeutic effects have been clinically demonstrated; nevertheless, such strategies are associated with certain constraints. For instance, treatments that focus on systemically negating IL-1β (i.e., anakinra, rilonacept, and canakinumab) have been reported to result in an escalated peril of infections. Therefore, given the therapeutic promise of an NLRP3 inhibitor, the concerted escalated venture of the scientific sorority in the advancement of small molecules focusing on direct NLRP3 inflammasome inhibition is quite predictable.

Abstract
Background Oesophageal cancer both squamous cell [SCC] and adenocarcinoma have poor outcomes with high morbidity and mortality. Our hospital-based registry for year 2017-2018 showed that oesophageal cancer constituted 22.7% of annual case load. The main objective of this study was to determine the presence of HER-2 receptors in patients with oesophageal carcinoma in our region. Methodology From September 2018 to September 2019, data regarding expression of HER-2 receptors was analysed in 133 patients of oesophageal carcinoma. Data were statistically described as frequencies (number of cases) and percentages where appropriate. Chi-square and Fischer's exact test was used to find out the association between categorical variables. A P value less than 0.05 was considered as statistical significant at 95% confidence interval. The statistical analysis was performed using SSPS [statistical package for the social sciences] software version 17.0. Results A total of 133 patients were taken into study. Majority of patients were males (96) with mean age of 52 years. Squamous cell carcinoma was predominant histology. HER-2 receptor positivity was seen in 6.01% of patients. Patients with HER-2 receptor positivity presented in advanced stage with poor functional status and poor grades of differentiation. Statistically significant correlation of Her-2 expression was seen with stage (p = 0.001) and pathology of tumour (p = 0.0001). Conclusion Squamous cell carcinoma of oesophagus still predominates in North-eastern part of India. For studying the role of effective targeted therapies knowledge of frequency of HER-2 receptor positivity is of utmost importance in our population, and our study aims to answer this question. The present study shows low prevalence of HER-2 neu overexpression in our community, probably due to disproportionately high incidence of SCC compared to adenocarcinoma. Patients with HER-2 receptor positivity presented in advanced stage with poor functional status and poor grades of differentiation.

Abstract
Soil-transmitted helminthiasis is a major disease burden in developing countries, with a considerable share borne by India. Currently, the principal strategy of the World Health Organization for the control of soil-transmitted helminths (STHs) is mass deworming in the high-risk population based on the prevalence and intensity of infection in a region. However, the disease load of STH remains unknown in many regions. A cross-sectional study was conducted in 2017 among children in the age group of 5-13 years in Barpeta, Assam, to ascertain the prevalence of STH infection in school-aged children and its probable risk factors. Socio-demographic and epidemiologic data were gathered using a piloted questionnaire. Geohelminths were identified by the Kato-Katz method. Association with probable risk-factors was analyzed by binomial logistic regression. Overall, 16.3% [95% confidence interval (CI) = 12.9-19.8] of children were found to be infected with one or more of the three STHs. Ascaris, hookworm, and Trichuris infections were observed in 9.4%, 7.4%, and 5.3%, respectively. The strongest predictors for the presence of any STH with multivariable analysis were open defecation (habitual or occasional), lack of proper handwashing, living in homes affected by flood, and age group of 8-10 years. The availability of proper handwashing stations in schools was found to be protective against Trichuris. Awareness among the people regarding sanitation and personal hygiene, particularly in the post-flood scenario, is imperative for sustainable control of STH infections. Preventive deworming should be continued; however, the time and frequency must be adjusted according to the prevailing climatic conditions in the region under study.

Abstract
PURPOSE Hepatitis C virus is a major cause of chronic hepatitis with seven known genotypes. Uttarakhand is a north Indian state in the Sub-Himalayan region where the genotypic distribution of HCV is largely unknown. This study was undertaken in order to assess the pattern of genotype and subtype and understand the risk factors leading to transmission of Hepatitis C virus in this understudied region. METHODS Anti-HCV reactive cases were selected for determination of the circulating genotypes. Viral RNA was confirmed by real-time PCR. Strains were amplified and sequenced using Sanger's methods. Phylogenetic tree was constructed to determine the genotype. RESULTS Genotype 3 was found to be the predominant genotype majority being subtype 3a and 3b followed by genotype 1. Subtypes 3g and genotype 4a were also observed. Major risk factor found was parenteral injection therapy from unregistered medical practitioners for minor ailments. CONCLUSIONS Findings of our study will help in tailoring management and prevention protocols for HCV for the people of this region.

Abstract
Background Esophageal cancers, both squamous cell and adenocarcinoma, have poor outcomes with high morbidity and mortality. Our hospital-based registry for the year 2017 to 2018 showed that esophageal cancer constituted 22.7% of annual caseload. Most of our patients present in advanced stages. The aim of this article was to study the role of hormonal receptors in patients with esophageal cancer. Methods This is a single-institution, prospective, observational study in patients with esophageal carcinoma. Hormonal receptors (estrogen receptor [ER]-α and progesterone receptors) were studied in tumor tissue. Of 160 patients, receptor status was analyzed in 133 patients. Chi-square test was used for the correlation of categorical variables. The value of p < 0.05 was considered as statistically significant. Results A total of 133 patients was taken into the study of which 96 were males and 37 were females. The mean age of patients was 52 years. Carcinoma esophagus was predominantly seen in males. Estrogen and progesterone receptors were positive in 9.02 and 4.51% of the study population, respectively. Patients with hormonal receptor positivity presented with poor functional status, higher grades of dysphagia, higher stage, and most of the tumors were poorly differentiated with statistically significant p -values. Conclusion Despite recent advances in various fields of oncology, outcomes of esophageal carcinoma have not improved significantly. Hence, a study of new pathways of pathogenesis in carcinogenesis of esophageal carcinoma is essential. Few recent evidences including our study shows that the hormonal milieu is responsible in the pathogenesis of carcinoma esophagus. The utilization of this data and future study of the role of hormonal therapy might lead to improved outcomes in patients with carcinoma esophagus.

Abstract
Soil-transmitted helminths (STHs) are widely distributed globally and India is a significant contributor to the overall global burden of the disease. Microscopic methods like Kato-Katz (K-K) thick smear and direct smear microscopy by wet mount (DSM) are widely used for STH diagnosis due to their ease in performance. Still, low sensitivity proves to be a significant limitation of these methods. This study explores the diagnostic performance of two and three consecutive-day stool samples compared to the common practice of single stool sample examination. We observed that the three consecutive-day stool examination technique increased overall helminth positivity from 12% to 16.3% in K-K and 11.5-15.9% in DSM, indicating that multiple sampling can diagnose intestinal helminthiasis more accurately. A significant increase in the intensities of hookworms (by 37.5%; p value: 0.001) and Trichuris trichiura (by 47.8%; p value: 0.037) (measured in terms of fecal egg count) was also observed. The methods undertaken in the current study are comparable in detecting the helminths as the marginal increase in positivity by K-K (16.32% vs. 15.86%) was statistically insignificant.

Abstract
INTRODUCTION It becomes a challenge for a teacher to find a student-friendly approach to teach too many students in a class. The teaching methods used during medical education have a significant impact on learning among medical students. A practical and informative teaching technique is considered an essential component of that education. The present study aimed to determine the best interactive teaching method based on Indian medical undergraduates' perceptions. MATERIALS AND METHODS The current investigation was a cross-sectional descriptive study that included 100 undergraduate medical students. A structured sample class on a specified topic was conducted using Microsoft PowerPoint (PPT) and a "chalk and talk" (CNT) method. Students' opinions of the class were assessed via a Likert scale questionnaire in which, for each of the two methods, the students were asked to rank twelve comments on a four-point scale: strongly agree, agree, disagree, or strongly disagree. Descriptive statistics were calculated to evaluate the distributions of their responses. The z test for two proportions was used to test a significant difference in respondents' proportions towards various perceptions regarding the two teaching methods under study. The data were analyzed using SPSS software version 22. RESULTS Students understood the lesson content better when the teacher used the CNT approach (p<0.005). The CNT method was also associated with better interaction than the PPT technique (p=0.03) and facilitated better student concentration and retention of the class content (p=0.03). The students reported that there was less eye contact associated with the PPT technique (61%) but found the content thus delivered fascinating (78%), informative (91%), and organized (85%) as compared to the CNT approach. CONCLUSION The traditional CNT approach is an effective classroom teaching method. The current study highlights student preferences for a combined teaching method that includes CNT and PPT.

Abstract
Background Coronavirus disease is primarily transmitted through the respiratory route and bodily contact. The fatality in COVID-19 cases was alarming in the initial days. This study analyzes hematological and biochemical markers of COVID-19 non-survivors. Material and methods In this single-center study, records of 249 patients hospitalized with COVID-19 were studied for hematological profile and biochemical markers. Records of patients with laboratory-confirmed COVID-19 disease hospitalized between April 14, 2020, to August 15, 2020, were included in the analysis. Results Significantly, the disease mortality was associated with increased procalcitonin (P < 0.05), C-reactive protein (P < 0.05), aspartate transaminase (P < 0.05), serum potassium (P < 0.05), neutrophils count (P < 0.05), white blood cell count (P < 0.05), prothrombin time (P < 0.05) and activated prothrombin time (P < 0.05) in patients reported abnormal x-ray findings. Further, patients with abnormal radiological findings significantly showed a reduced level of lymphocyte counts (P < 0.05), oxygen saturation (P < 0.05), and partial oxygen pressure (P < 0.05). Reduced level of aspartate aminotransferase (P < 0.05), alanine aminotransferase (P < 0.05) and lactate dehydrogenase (P < 0.05) reported significant association with mortality among patients with COVID-19. Conclusions The clinicians may consider the hematological and biochemical parameters in the patients with COVID-19 in future decision-making. These indicators might support clinical decisions to identify high fatality cases and poor diagnosis in the initial admission phase. In COVID-19 patients, we recommend close monitoring on procalcitonin, C-reactive protein, neutrophils count, and white blood cell count as a clinical indicator for potential progression to critical illness.

Abstract
Background Toxoplasma gondii infects 30-50% of the world's population with high diversity in the geo-epidemiology and seroprevalence. The burden of toxoplasmosis and its determinants from remote and vulnerable regions of India is unknown. Therefore, this study aim to evaluate the prevalence of toxoplasma antibodies and factors associated with seropositivity among individuals from Uttarakhand and adjoining areas. Methods Serum samples from 442 cases were tested for anti-Toxoplasma IgG and IgM antibodies by Enzyme-linked Immunosorbent Assay. Association of seropositivity of toxoplasmosis with age, gender, place of residence, dietary habits, and comorbidities were analyzed using binary logistic regression analysis. Results The overall Toxoplasma seropositivity was found to be 36.88% [95% Confidence Interval (CI)=30.40-39.28]. While anti-T. gondii IgG was present in 34.84% [95% CI=30.40-39.28], anti-IgM was detected in 6.33% [95% CI=4.06-8.61]. The overall and IgG seroprevalence increased with age in both the genders and there was a sharp increase in the seropositivity after the age of 40 years [adjusted Odds Ratio (aOR)=2.98, p-value=0.030]. The seropositivity rate was significantly higher in individuals from Uttarakhand in both the hilly region (aOR=5.61; 95%CI:[2.14-14.68]) and plains (aOR=5.14; 95%CI:[2.2-12.02]). Multivariable logistic regression analysis also showed that being rural residents (aOR=3.23; 95%CI:[1.67-6.23]) and presence of comorbidities (aOR=8.64; 95%CI:[4.62-16.18]) were potential risk factors of Toxoplasmosis. On the other hand, consumption of vegetarian diet was found to have a protective effect (aOR=0.46; 95%CI:[0.28-0.75]). Conclusion Seroprevalence of T. gondii antibodies was relatively high in Uttarakhand, particularly in rural and hilly terrain, indicating a necessity for the implementation of integrated public health strategies to prevent and control toxoplasmosis in this region.

Abstract
Objectives The clinical factors affecting a patient's condition monitored over time could be useful not only to decide on an intervention that may increase the patients' possibilities of survival but also to predict the treatment outcome. Therefore, this study evaluates the clinical factors as predictors of mortality among severe sepsis patients admitted in the intensive care unit (ICU) of a tertiary care center. Method We did a prospective study on over 50 life-threatening infective cases with different causes admitted in the ICU. Clinical and biochemical parameters like temperature, heart rate, blood pressure, bicarbonate levels, blood lactate levels, and pH were monitored at admission, after 24 hours, and after 72 hours. The statistical analysis was done using Microsoft Excel (Microsoft Corporation, Redmond, WA) and the Statistical Package for the Social Studies (SPSS) version 22 (IBM Corp., Armonk, NY). We have obtained ethical clearance from the ethics committee (human) of Assam Medical College and Hospital, Dibrugarh. Before the collection of the data, we also took informed consent from the participants. Results The mean age of non-survivors was 44.35±11.64 years and that of survivors was 36.60±9.28 years, and the difference was statistically significant (p-value <0.003). An analysis of values of the various vital signs indicated substantial differences in the mean at different time intervals among survivors and non-survivors (p-value <0.05). Among non-survivors, mean temperature, pulse, and rate of respiration were observed to increase over time while blood pressure and oxygen saturation levels were significantly decreasing. Compared to survivors, the mean lactate levels of non-survivors at different time intervals were statistically significant (p-value <0.05). It is also observed that the pH of non-survivors was lower than survivors, and the mean pH value significantly different at different time intervals among the two groups (p-value <0.05). Conclusion The temperature, pulse, rate of respiration, blood pressure, and oxygen saturation levels are essential determinants of patient mortality in those suffering from a severe infection, besides serial lactate levels, bi-carbonate levels, and pH levels.
