Background Prevalence of IgG antibodies against SARS-CoV-2 infection provides essential information for deciding disease prevention and mitigation measures. We estimate the seroprevalence of SARS-CoV-2 specific IgG antibodies in District Srinagar. Methods 2906 persons >18 years of age selected from hospital visitors across District Srinagar participated in the study. We tested samples for the presence of SARS-CoV-2 specific IgG antibodies using a chemiluminescent microparticle immunoassay-based serologic test. Results Age- and gender-standardized seroprevalence was 3.6% (95% CI 2.9% to 4.3%). Age 30–69 years, a recent history of symptoms of an influenza-like-illness, and a history of being placed under quarantine were significantly related to higher odds of the presence of SARS-CoV-2 specific IgG antibodies. The estimated number of SARS-CoV-2 infections during the two weeks preceding the study, adjusted for test performance, was 32602 with an estimated (median) infection-to-known-case ratio of 46 (95% CI 36 to 57). Conclusions The seroprevalence of SARS-CoV-2 specific IgG antibodies is low in the District. A large proportion of the population is still susceptible to the infection. A sizeable number of infections remain undetected, and a substantial proportion of people with symptoms compatible with COVID-19 are not tested.

BACKGROUND: SARS-CoV-2 infection (COVID-19) poses a tremendous challenge to healthcare systems across the globe. Serologic testing for SARS-CoV-2 infection in healthcare workers (HCWs) may quantify the rate of clinically significant exposure in an institutional setting and identify those HCWs who are at greatest risk. METHODS: We conducted a survey and SARS-CoV-2 serologic testing among a convenience sample of HCWs from 79 non-COVID and 3 dedicated COVID hospitals in District Srinagar of Kashmir, India. In addition to testing for the presence of SARS-CoV-2–specific immunoglobulin G (IgG), we collected information on demographics, occupational group, influenza-like illness (ILI) symptoms, nasopharyngeal reverse transcription polymerase chain reaction (RT-PCR) testing status, history of close unprotected contacts, and quarantine/travel history. RESULTS: Of 7,346 eligible HCWs, 2,915 (39.7%) participated in the study. The overall prevalence of SARS-CoV-2–specific IgG antibodies was 2.5% (95% CI, 2.0%-3.1%), while HCWs who had ever worked at a dedicated COVID-19 hospital had a substantially lower seroprevalence of 0.6% (95% CI, 0.2%-1.9%). Higher seroprevalence rates were observed among HCWs who reported a recent ILI (12.2%), a positive RT-PCR (27.6%), a history of being put under quarantine (4.9%), and a history of close unprotected contact with a person with COVID-19 (4.4%). Healthcare workers who ever worked at a dedicated COVID-19 hospital had a lower multivariate-adjusted risk of seropositivity (odds ratio, 0.21; 95% CI, 0.06-0.66). CONCLUSIONS: Our investigation suggests that infection-control practices, including a compliance-maximizing buddy system, are valuable and effective in preventing infection within a high-risk clinical setting. Universal masking, mandatory testing of patients, and residential dormitories for HCWs at COVID-19–dedicated hospitals is an effective multifaceted approach to infection control. Moreover, given that many infections among HCWs are community-acquired, it is likely that the vigilant practices in these hospitals will have spillover effects, creating ingrained behaviors that will continue outside the hospital setting.

Background: Supraclavicular brachial plexus block is a good alternative to general anesthesia in surgeries of elbow, forearm, wrist and hand. The aim of this study was to assess the effect of dexamethasone as an adjuvant with bupivacaine in supraclavicular brachial plexus block in upper limb surgeries.Methods: This study was carried out on 60 adult patients of both sexes planned for upper limb surgery during the period from May 2015 to Jan 2016 after approval by the institutional Ethical Committee. Inclusion criteria were American Society of Anesthesiologists physical Status I-II and age between 18 and 50 years. Patients were randomly allocated to two groups of 30 patients each [group I (bupivacaine alone) and group II (bupivacaine + dexamethasone)]. Group I received 30ml of 0.5% bupivacaine with 2ml normal saline while group II received 30ml of 0.5% bupivacaine with 2ml (8mg) dexamethasone for supraclavicular brachial plexus block. Statistical analysis was performed with SPSS for Windows (SPSS Inc., Chicago, IL, USA), version 16.0. For analysis of demographic data and comparison of groups, χ2, unpaired Student's t-test and Mann-Whitney U-test were performed. Power of significance p-value of <0.05 was considered to be statistically significant. We evaluated onset, quality and duration of sensory and motor block along with side effects if any.Results: The mean onset of sensory and motor block in Group I and II was statistically insignificant. The duration of motor and sensory block was significantly prolonged in Group II than in Group I. There were no statistically and clinically significant differences in respiratory and hemodynamic parameters.Conclusions: We conclude that dexamethasone as an adjuvant in supraclavicular brachial plexus block prolongs the duration of motor and sensory block with insignificant side effects.

Background and objective: SARS-CoV-2 infection poses tremendous challenge to the healthcare system of nations across the globe. Serological testing for SARS-CoV-2 infection in healthcare workers, which form a high-risk group, helps in identifying the burden of hidden infection in an institutional setting. Methods: We present the results of a cross-sectional serosurvey in healthcare workers from two different hospital settings based on their role in the management of SARS-CoV-2 patients in District Srinagar, Kashmir. In addition to testing for the presence of SARS-CoV-2 specific IgG, we collected information on influenza-like symptoms in the last four weeks and the status of RT-PCR testing. SARS-CoV-2 specific IgG antibodies were detected in serum samples using a sensitive and specific chemiluminescent microparticle immunoassay technology. Interpretation and Conclusion: Of 2915 healthcare workers who participated in the study, we analysed data from 2905 healthcare workers. The overall prevalence of SARS-CoV-2 specific IgG antibodies was 2.5% (95% CI 2.0-3.1) in the healthcare workers of District Srinagar. Healthcare workers who had ever worked at a dedicated-COVID hospital had a substantially lower seroprevalence of 0.6% (95% CI: 0.2 - 1.9). Among healthcare workers who had tested positive for RT-PCR, seroprevalence was 27.6% (95% CI: 14.0 - 47.2).The seroprevalence of SARS-CoV-2 infection in healthcare workers of District Srinagar is low, reflecting that a high proportion of healthcare workers are still susceptible to the infection. It is crucial to lay thrust on infection prevention and control activities and standard hygiene practices by the healthcare staff to protect them from acquiring infection within the healthcare setting.

Gastric cancer is the second leading cause of death in the world. More than two-thirds of the patients are diagnosed at an advanced stage. Metastatic gastric cancer has poor prognosis with a median 5 years-survival rate of 7 %. Hematological parameters including leukocyte count, platelet count and their ratios have been used as prognostic indicators in several tumor types. The aim of the study was to examine an association of the difference in haematological parameters between gastric cancer patients and normal controls of Kashmir valley. We enrolled 210 subjects of which 110 were newly diagnosed gastric cancer cases and 100 were healthy controls. Participants were recruited from hospitals, clinics and radiology department of Shri Maharaja Hari Singh (SMHS) hospital Srinagar, India from May 2011 to Apr 2012. After informed consent, all patients were interviewed and examined and demographic and clinical information was collected. Blood samples were drawn for examination of hematological measures and for measurement of carcino embryonic antigen (CEA). We found the hematological parameters like: Hb (10 ± 2, P = 0.004), MCV (84.25 ± 5, p = 0.01), Granulocyte % (70.04 ± 10.63, p = 0.001), Lymphocyte % (26.12 ± 10.7, p < 0.0001), RDW (48 ± 10, p = 0.004) in gastric cancer patients and these were found to be highly decreased as compared to normal healthy controls where hematological parameters was in normal range. Our study was statistically significant (p < 0.005). The study suggests that the hematological parameters like HB, MCV, Granulocyte %, Lymphocyte % and RDW are decreased in gastric cancer patients and acts as an early marker in the prognosis and diagnosis of gastric cancer.
