ABSTRACT

In a pandemic like Covid-19, there are many countries of lower-earning cannot provide a complete locked-down within the duration of the detected case. The locked-down may result in famine throughout the region of underdeveloped countries after the outbreak. So, a conjectural setup of an epidemic has been studied by applying specific period of locked-down (30 days) in 5 different scenarios. The stochastic approach to the SEIR (Susceptible, Exposed, Infected and Recovered) model has been used to evaluate the dynamics and the effects of locked-down. It is observed that there exist a suitable period to apply locked-down where more susceptible escape from the infection. The effect of the early (as soon as the infected case detected) and late (with respect to the estimated peak of detected cases for no locked-down) implementation of the locked-down has also been studied and found that the late implementation of locked-down will take the least time to end the epidemic. The CFR (Case Fatality Rate) has also been found to be varied from 7.55 to 8.02 for all the considered scenarios.

ABSTRACT

Aim: To determine the demographic profile of pregnant females with COVID-19 infection. The outcome and prognosis in pregnant women with COVID-19 infection was also evaluated. Method and material:The study included 38 pregnant women with COVID-19 infection and hospital admission for at least 24 hours. Cause of admission was classified as obstetric and COVID-19-related. All the patients were COVID positive and were referred from other centres/ hospital to this facility andwas admitted to this hospital for delivery. Primary outcomes included maternal admission to intensive care unit (ICU), COVID-19 pneumonia, maternal mortality. The information on socio-demographic factors, pre-gestational chronic diseases (including cardiac, renal, endocrine, psychiatric, hematologic and autoimmune disease, cancer and HIV)and mode of delivery was collected. Results:The mean age of the patients was 28.8±6.2 years. The mode of delivery for 60.5%patients(23) was normal vaginal delivery and lower segmentcaesarean section in 39.5%(15) patients.94.7%(36) patients were asymptomatic in the present study. Maximum patients in the present studywere hospitalized for 3-5 days. Conclusion: COVID-19 infection was associated with higher rates of caesarean section in pregnant women. However, COVID-19 cannot be considered as an indication for caesareansectiondelivery. Patients with increased age have more days of hospitalization than younger patient.

ABSTRACT

Background: Individuals living in rural areas have higher obesity and obesity related co-morbidities than their urban counterparts. Understanding rural-urban differences associated with weight management may inform the development of effective weight management interventions for adults living in rural areas. Methods: The International Weight Control Registry (IWCR) is an online registry designed to assess factors contributing to successes and challenges with weight loss and weight loss maintenance across the world. We examined demographics, weight history and weight management strategies in a sample of urban and rural residents in the Midwestern U.S. (IA, IL, IN, KS, MI, MN, MO, ND, NE, OH, SD, WI). Participants were classified as rural or urban by the Rural-Urban Commuting Area Code. Analyses included Chi-square tests for proportions and independent t-test and Wilcoxon rank sum test for continuous variables. Results: The sample was 45% rural (n = 78 of a total N = 174) with a mean age of 50.3 years. Rural residents were more likely to be white, non-college graduates, and have lower family income compared with urban areas (p < 0.05). Rural and urban residents reported similar weight histories and strategies for weight management. Work-related physical activity was higher and weekday sitting time was lower in rural compared to urban residents (p < 0.01). These data could potentially be impacted by the relative number of residents working from home during COVID-19 (Urban: 59% vs. Rural: 37%, p < 0.05). Rural residents were more likely to report a lack of neighborhood walkability (p < 0.01) and healthy food availability (p < 0.05) compared with urban residents. Conclusions: These data suggest rural-urban differences in demographic characteristics, opportunity for leisure time physical activity, and the availability of heathy foods should be considered in the development of weight management interventions. The consistency of the observed findings will be evaluated at the regional, national and international levels as the size of the available sample in the IWCR increases.

ABSTRACT

With the outbreak of COVID-19 pandemic, several educational and business organizations have adopted online video conferencing platforms to facilitate their smooth functioning. These platforms have largely favored educational institutions for remotely conducting virtual classes over various electronic learning (e-learning) platforms. This has imposed challenges on existing Internet platforms for efficiently managing network performance generated from the extensive use of these platforms. In this paper, a framework for monitoring the effect of different network parameters, while using some well-known e-learning platforms is provided. The different LTE network performance parameters like uplink speed, downlink speed, network latency, and jitter are considered. We observed that the LTE network performance parameters obtained while using Microsoft Teams is optimum. Since, we observed that Microsoft Teams provided an optimal performance, we further perform analysis on Microsoft Teams. We further obtain the empirical distribution pertaining to the LTE network communication features by employing Gamma distribution. From our analysis, it is observed that the network throughput, latency, and jitter can be optimized to enhance the users’ quality of experience by employing the proposed strategy. © 2020 IEEE.

ABSTRACT

Airglow emissions which originate from the mesospheric and thermospheric altitudes have been routinely being monitored at Kolhapur (16.8 degrees N, 74.2 degrees E), Maharashtra, India, using ground base remote sensing imagers. We note that the observable amplitudes of very small-scale waves during April 2020 were significantly smaller than the regular observations. We investigate the reason for these low observable amplitudes. It is noted that drastic improvement in the quality of images was due to better contrast, which is attributed to significant reduction in greenhouse gases and aerosol loading in the atmosphere by the complete shutdown of local man-made emissions. Results suggest that lockdown had an important repercussion on the visibility through the improved air quality and thus better viewing conditions, which were reflected in the remotely sensed observations made with airglow imager.

ABSTRACT

Background: The typical CT manifestations of COVID-19 pneumonia include ground-glass opacity (GGO) with or without consolidation and superimposed interlobular septal thickening. These are often rounded in morphology and frequently bilateral, multilobar, posterior, peripheral, and basilar in distribution. The various atypical CT features of COVID-19 are seldom described in the literature. The study aims to enumerate the atypical pulmonary CT features in patients with COVID-19 pneumonia in correlation with the disease severity. Results: A total of 298 confirmed cases of COVID-19 pneumonia with positive reverse transcription polymerase chain reaction (RT-PCR) who underwent chest CT scans were retrospectively evaluated. The cohort included 234 (78.5%) men and 64 (21.5%) women and the mean age was 53.48 ± 15.74 years. The most common presenting symptoms were fever [n = 197 (66.1%)] and cough [n = 139 (46.6%)]. Out of 298 cases of COVID-19 pneumonia, 218 cases (73.1%) showed typical CT features while 63 cases (21.1%) showed atypical CT features with concurrent classical findings and the remaining 17 cases (5.8%) were normal. Among the atypical CT features, the most common was pulmonary cysts [n = 27 (9%)]. The other features in the order of frequency included pleural effusion [n = 17 (5.7%)], nodules [n = 13 (4.3%)], bull’s eye/target sign[n = 4 (1.3%)], cavitation [n = 3 (1.0%)], spontaneous pneumothorax [n = 2 (0.6%)], hilar lymphadenopathy [n = 2 (0.6%)], spontaneous pneumo-mediastinum with subcutaneous emphysema [n = 1 (0.3%)], Halo sign [n = 1 (0.3%)], empyema [n = 1 (0.3%)] and necrotizing pneumonia with abscess [n = 1 (0.3%)]. Conclusion: CT imaging features of COVID-19 pneumonia while in a vast majority of cases is classical, atypical diverse patterns are also encountered. A comprehensive knowledge of various atypical presentations on imaging plays an important role in the early diagnosis and management of COVID-19. © 2021, The Author(s).

ABSTRACT

SARS-CoV-2 infection in pregnancy and its adverse outcome on the mother as well on the fetus is emerging as an important concern, but knowledge about the prognosis is limited. In our prospective observational study total of 56 pregnant women admitted in the isolation ward of our institution were included. All women were presented with common symptoms like fever, tiredness, headache, sore throat, and cough. Three women diagnosed SARS-CoV-2/COVID-19 positive by Reverse Transcription Polymerase Chain Reaction (RTPCR) examination of the nasopharyngeal swab. All three neonates were tested negative for SARS-CoV-2 infection. The three mothers also recovered with routine care and returned home after 7 days with advice for a safe home for further 7 days. SARS-CoV-2 infection in pregnancy mostly appears in the later part of pregnancy and management is almost like the general population. There is no increased risk of severe disease during pregnancy. Neonates are mostly protected from disease transmission due to immune modulation during pregnancy.

ABSTRACT

Hydroxychloroquine, an antimalarial, is being used worldwide for prophylaxis and treatment of Corona virus disease-19 (COVID-19). Though the drug is commonly used in many chronic inflammatory diseases for protracted periods, its safety in the new indication is still under scrutiny. Therefore, this institute based study sought to assess the acute adverse effects of hydroxychloroquine among in-house health care professionals who were taking the drug for COVID-19 prophylaxis. A questionnaire seeking information on the use of the drug was prepared and disseminated electronically to the target population. The responses were also received electronically and analysed. The participants (n=54) had taken prophylaxis for 1-7 weeks. The most common adverse effects in the cohort were nausea (02) and skin rash (02). The total number of adverse effects reported by the participants was 08. One incidence each of gastric upset (01), dizziness (01), pain abdomen (01), and chest tightness (01) was reported. None of the adverse effects were serious. Our study indicates that the prophylactic weekly single dose of hydroxychloroquine is not associated with any serious adverse effects within 1-7 weeks of initiation. Elucidation of the long term and chronic adverse effects, if any, requires further studies.
