Probabilistic Approach to COVID-19 Data Analysis and Forecasting Future Outbreaks Using a Multi-Layer Perceptron Neural Network.

The present outbreak of COVID-19 is a worldwide calamity for healthcare infrastructures. On a daily basis, a fresh batch of perplexing datasets on the numbers of positive and negative cases, individuals admitted to hospitals, mortality, hospital beds occupied, ventilation shortages, and so on is published. Infections have risen sharply in recent weeks, corresponding with the discovery of a new variant from South Africa (B.1.1.529 also known as Omicron). The early detection of dangerous situations and forecasting techniques is important to prevent the spread of disease and restart economic activities quickly and safely. In this paper, we used weekly mobility data to analyze the current situation in countries worldwide. A methodology for the statistical analysis of the current situation as well as for forecasting future outbreaks is presented in this paper in terms of deaths caused by COVID-19. Our method is evaluated with a multi-layer perceptron neural network (MLPNN), which is a deep learning model, to develop a predictive framework. Furthermore, the Case Fatality Ratio (CFR), Cronbach's alpha, and other metrics were computed to analyze the performance of the forecasting. The MLPNN is shown to have the best outcomes in forecasting the statistics for infected patients and deaths in selected regions. This research also provides an in-depth analysis of the emerging COVID-19 variants, challenges, and issues that must be addressed in order to prevent future outbreaks.

Ventilatory Support for COVID-19 Patients.

Coronavirus Disease (COVID-19), first emerged in Wuhan, China, in December 2019 and has now become a worldwide health emergency. The symptoms of Coronavirus vary from anosmia, fever, and cough to severe complications such as acute respiratory distress syndrome, which often require intubation and subsequent ventilation. Procedures such as these are aerosol-generating, and this adds additional challenges due to the risks posed to staff. In this brief article, we discuss the need for ventilation, risks raised to healthcare staff in this context, and ways to potentially mitigate these risks. We also discuss emerging themes, including phenotypes of COVID-19 and the role of prone positioning.

At the heart of COVID-19.

Coronavirus disease (COVID-19) first presented in Wuhan, Hubei province, China in December 2019. Since then, it has rapidly spread across the world, and is now formally considered a pandemic. The disease does not discriminate but increasing age and the presence of comorbidities are associated with severe form of the disease and poor outcomes. Although the prevalence of COVID-19 in patients with cardiovascular disease is under-reported, there is evidence that pre-existing cardiac disease can render individuals vulnerable. It is thought that COVID-19 may have both a direct and indirect effect on the cardiovascular system; however, the primary mechanism of underlying cardiovascular involvement is still uncertain. Of particular interest is the role of angiotensin-converting enzyme 2, which is well known for its cardiovascular effects and is also considered to be important in the pathogenesis of COVID-19. With a range of different drug candidates being suggested, effective anti-virals and vaccines are an area of on-going research. While our knowledge of COVID-19 continues to rapidly expand, this review highlights recent advances in our understanding of the interaction between COVID-19 and the cardiovascular system.

The need to manage the risk of thromboembolism in COVID-19 patients

COVID-19 first presented in Wuhan, Hubei Province, China, in December 2019. Thought to be of zoonotic origin, it has been named SARS-CoV-2 (COVID-19) and has spread rapidly. As of April 20th, 2020, there have been more than 2.4 million cases recorded worldwide. The inflammatory process, cytokine storm, and lung injury that are associated with COVID-19 can put patients at an increased risk of thrombosis. It is uncertain what the total incidences of thrombotic events in COVID-19 patients is currently at. Those with more severe disease and with other risk factors, including increasing age, male sex, obesity, cancer, comorbidities, and intensive care unit admission, are at higher risk of these events. However, there is little international guidance on managing these risks in COVID-19 patients. In this paper, we explore the current evidence and theories surrounding thrombosis in these unique patients and reflect on experience from our center.
