RESUMO

This study describes the deployment of an image processing approach for finding COVID-19 affected lungs. Medical scans are useful in diagnosing illnesses and determining if organs are working normally. Medical image processing is an ongoing research subject in where numerous ways are used to help diagnosis, as well as different image processing techniques that may be used. Picture processing was used in this work, which includes image pretreatment, histogram leveling, smothering, eroding, and dilation. The usage of 2-bit picture is selected since this characteristic is well-known and there are several resources accessible. The Open CV library, which includes a plethora of image processing functions, is likewise free to use. Our experiment has shown how COVID-19 affected lung disorders can easily be identified with the help of a 2-bit image segmentation technique. The plan comprises (1) using a deep robust acquisition access to portion proper regions of interest from bleak medical examination image sizes of 903 total, (2) using a propagative neural network to improve contrast, sharpness, and illuminance of image contents, and (3) from the beginning to the conclusion, a regression strategy plan was used to accomplish medical picture categorization by material design in deep neural networks.

RESUMO

The unprecedented crisis of COVID-19 pandemic has wreaked havoc across the whole world. The menacing disease has not only claimed lives of innumerable people but also rattled all the countries pushing them at the face of an inevitable and inimitable global meltdown. Ever since its outbreak, all major sectors of each and every nation have been stymied, and India is no exception. In this context, it becomes highly relevant to deliberate on the impact of COVID-19 on different sectors of India. The current case study is attempted in discussing the impact of COVID-19 on healthcare and technology sector of India, in which both the merits and demerits of the impact of COVID-19 will be highlighted. To serve this purpose, an anonymous choice of various relevant subsectors has been made that has been delved into which will ultimately help to have an intimate understanding of the effects triggered by COVID-19 on the sectors of healthcare and technology. To strengthen the worth of the present case-based study, few surveys have also been conducted among the people of India especially from selected districts in the states of West Bengal, Jharkhand, and Tamil Nadu, through which robust empirical insights will be reflected. © 2022 Elsevier Inc.

RESUMO

BACKGROUND AND AIMS: Patients on kidney replacement therapy (KRT) are at a particularly high risk of mortality from COVID-19. In this study, we investigated COVID-19 mortality in KRT patients in the first and second waves of the pandemic and potential reasons for any difference in mortality between the two waves. METHOD: Data from the European Renal Association COVID-19 Database (ERACODA) of KRT patients who presented between 1 March 2020 and 28 February 2021 with COVID-19 were analyzed. The cut-off for dividing the first and second waves was set for 1 August 2020. The primary study outcome was 28-day mortality. Multivariable Cox proportional-hazards regression analysis was used to examine the relationship between the pandemic waves and mortality with follow-up time starting at the date of presentation. Dialysis patients and kidney transplant recipients were analyzed separately. RESULTS: Among 3004 dialysis patients (1253 in the first and 1751 in the second wave), the 28-day mortality was 24.3% in the first wave and 19.6% in the second wave (P = .002). Compared with the first wave, in the second wave, identification of patients with limited to no symptoms was higher (14.3% versus 24.8%;P < .001), hospitalization was lower (71.3% versus 44.3%;P < .001), but in-hospital mortality was similar (30.4% versus 30.7%;P = .92) (Fig. 1). Crude hazard ratio (HR) for 28-day mortality in the second wave was 0.77 (95% CI: 0.66, 0.89). However, in a fully adjusted model, when correcting for differences in patient and disease characteristics, including the reason for COVID-19 screening and disease severity, the HR for mortality in the second wave was 0.93 [95% confidence interval (95% CI): 0.79-1.10]. When follow-up was chosen to start at the date of first symptoms to account for possible lead-time bias, crude HR for 28-day mortality in the second wave was 0.90 (95% CI: 0.75-1.07) and the fully adjusted HR was 0.98 (95% CI: 0.81-1.18). Among 1035 kidney transplant recipients (475 in the first and 560 in the second wave), results were essentially similar except that patients in the second wave were younger (55.6 years versus 58.2 years;P = .002), and crude HR for 28-day mortality from the date of first symptoms was 0.66 (95% CI: 0.47-0.93), whereas the fully adjusted HR was 1.02 (95% CI: 0.70-1.49). CONCLUSION: Among patients on KRT with COVID-19, 28-day mortality rates were lower in the second wave compared with the first wave. However, a greater proportion of patients with minimal symptoms, lead-time bias in dialysis patients, and younger age in kidney transplant recipients possibly explain the lower mortality during the second wave. Any improvement in patient management during the second wave may not be the main reason for lower mortality. (Table Presented).

RESUMO

The coronavirus disease 2019 (COVID-19) pandemic has witnessed a total of 2, 631, 338 infected cases as on April 22, 2020. The first case being recorded in January 2020, followed by more than 20, 000 case in a matter of 3 months creating a tremor among the population of India. The United States tops the total number of infected cases in the world with 8, 45, 822 cases, followed by Spain summing up to 2, 08, 389 cases. India having 21, 370 total infected cases, along with 4370 recoveries and a total death toll of 681, ranks 17th among the other countries. In this study, a detailed summary has been conducted on how India is working together to fight this pandemic. The countrymen, along with following the strict instructions provided by the WHO, have set up new rules to fight this disease. This study includes the various medical procedures adopted by the government of India along with the economic guidelines for its fellow citizens during these hard times;a geospatial approach has also been used to identify the infected regions of the country and their pandemic control methods in the 1-month period (22 March-22 April). To date, being the second most populated developing country in the world, India has managed to control the spread of the virus to a large extent. The WHO has praised India’s efforts in monitoring the spread of the virus and has alerted India that a simple lockdown would not stop the spread of the virus. They have recommended India to increase the number of tests to segregate the people showing early/mild symptoms. The outcomes of the precautions taken are also discussed in this study. © 2022 Elsevier Inc.

RESUMO

We propose a battery-free temperature monitoring device that can be fitted inside the ear for an accurate body temperature measurement of a subject. The proposed application consists of two primary systems: 1) a battery-free temperature sensing ultra-high-frequency radio frequency identification sensory tag and 2) an auxiliary energy harvesting system, which enhances the sensing device's measurement accuracy and precision. The system can record changes in the localized body temperature of authenticated users with an average latency of 501 ms. The assembly demonstrated a temperature average accuracy of +/- 0.14 degrees C operating at 866 MHz. The system performance demonstrated high stability and repeatability of reported temperature measurements. The device's dimension is a form factor that can easily fit in a front shirt pocket, with a wire tethered earbud temperature sensor. The system is developed to make sensor measurements without requiring a battery for the device. Measurements are made remotely as users pass by checkpoints installed throughout a building. The device is a cost-effective solution for monitoring body temperature in work environments.

RESUMO

Neurodegenerative disorders, including Alzheimer’s and Parkinson’s, are the leading causes of dementia in the elderly. In the coming days, an alarming upsurge of dementia patients is expected with increasing life expectancy. This is the scenario not only in the developed world but also in the developing world, where older people live in vulnerable situations. Even in the COVID-19 (coronavirus disease-19) pandemic, the situation has worsened. Due to the limitations of conventional therapeutic strategies, it is necessary to explore integrated approaches consisting of both pharmacological and non-pharmaceutical interventions. As existing anti-dementia drugs pose many adverse effects on patients, pharmacological intervention through naturally occurring agents should be employed to explore targeted therapy. Alongside, non-pharmacological interventions such as cognitive and motor rehabilitation, occupational therapy, and psychological therapy need to be explored. From this perspective, multidisciplinary approaches need to be employed in order to develop a sustainable patient-friendly treatment strategy for the management of these emerging health issues with tremendous social burdens. © 2022, Bangladesh Society for Microbiology, Immunology and Advanced Biotechnology.

RESUMO

Wearing masks has been one of the key methods of preventing the spread of COVID-19. Being able to ensure that the people entering the premises of any institution are wearing masks reduces the risk of the people within those premises to be affected by the virus. This paper describes the approach of taking Google's pre-trained Inception-V3 architecture and using transfer learning to adapt it for mask detection in Indian scenario. The mask detection model was converted to a TFlite version deployable on Raspberry Pi 3 Model B. Pi camera was used for data capture. All hardware chosen and software adaptations were done with the focus of making the model portable and affordable. This model was created with the focus of providing a cost-efficient way to enforce preventive measures during this pandemic. © 2021 IEEE.

RESUMO

The cryptocurrency markets are perceived as being dominated by Bitcoin leading the overall system dynamics. Although the previous empirical evidence points towards strong connections among selected cryptocurrencies or, from the other side, weak dependence between Bitcoin and traditional financial assets, a focused study on the dynamics of return and volatility connectedness among a wider range of cryptocurrencies is lacking, and more so, one directed towards the very first actual critical period of the global economy coinciding with relevant crypto-markets. Using data for the 10 most capitalized cryptocurrencies between 1st October 2017 and 5th January 2021, we examine how cryptocurrencies interact and whether they have a clear leader, with a special focus on differences with respect to investment horizons and how the relationship structure evolves in time. We uncover a structural change in the connectedness evolving in 2020 as the market restructures in reaction to the unprecedented monetary injections as a counter to the COVID-19-induced economic standstill. The structural change is shown not only for cryptocurrencies considered separately but also when we jointly examine them with traditional assets. © 2022 Elsevier B.V.

RESUMO

We propose a battery-free temperature monitoring device that can be fitted inside the ear for an accurate core-body temperature (CBT) measurement of a subject. The system can record instantaneous changes in the localized body temperature of authenticated users. The proposed application consists of 2 primary systems: (i) a battery-free temperature sensing Ultra High Frequency Radio Frequency Identification (UHF RFID) sensory tag and (ii), an auxiliary energy harvesting system, which enhances the sensing devices measurement accuracy and precision. The assembly demonstrated a temperature average accuracy of 0.14 C operating at 866 MHz. The system performance demonstrated high stability and repeatability of reported temperature measurements. The devices dimension is a form factor that can easily fit in a front shirt pocket, with a wire tethered earbud temperature sensor. The system is developed to make sensor measurements without requiring a battery for the device. Measurements are made remotely as users pass by checkpoints installed throughout a building.

RESUMO

The last two decades have witnessed the emergence of three deadly coronaviruses (CoVs) in humans: severe acute respiratory syndrome coronavirus (SARS-CoV), Middle East respiratory syndrome coronavirus (MERS-CoV), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). There are still no reliable and efficient therapeutics to manage the devastating consequences of these CoVs. Of these, SARS-CoV-2, the cause of the currently ongoing coronavirus disease 2019 (COVID-19) pandemic, has posed great global health concerns. The COVID-19 pandemic has resulted in an unprecedented crisis with devastating socio-economic and health impacts worldwide. This highlights the fact that CoVs continue to evolve and have the genetic flexibility to become highly pathogenic in humans and other mammals. SARS-CoV-2 carries a high genetic homology to the previously identified CoV (SARS-CoV), and the immunological and pathogenic characteristics of SARS-CoV-2, SARS-CoV, and MERS contain key similarities and differences that can guide therapy and management. This review presents salient and updated information on comparative pathology, molecular pathogenicity, immunological features, and genetic characterization of SARS-CoV, MERS-CoV, and SARS-CoV-2; this can help in the design of more effective vaccines and therapeutics for countering these pathogenic CoVs.
