ReviewSARS, MERS and SARS-CoV-2 (COVID-19) treatment: a patent review.
Coronavirus has been responsible for several virus outbreaks since 2003, caused by SARS-CoV-1, MERS-CoV, and currently SARS-CoV-2 (COVID-19), the causative agent of coronavirus disease in 2019. COVID-19 has become a global public health emergency because of its high virulence and mortality capacity. This patent review aims to provide an overview of the patents that present possible treatments for SARS-CoV-1, SARS-CoV-2 and MERS-CoV. ⋯ The various antiviral alternatives presented in this review offer therapeutic options to fight coronavirus infections. If shown to be effective, these drugs may be extremely important in the current pandemic.

Mathematical model of infection kinetics and its analysis for COVID-19, SARS and MERS.
The purpose of this paper is to reveal the spread rules of the three pneumonia: COVID-19, SARS and MERS. We compare the new spread characteristics of COVID-19 with those of SARS and MERS. ⋯ Parametric analysis shows that the growth rate of COVID-19 is about twice that of the SARS and MERS, and the COVID-19 doubling cycle is two to three days, suggesting that the number of COVID-19 patients would double in two to three days without human intervention. The infection inhibition constant in Hubei is two orders of magnitude lower than in other regions, which reasonably explains the situation of the COVID-19 outbreak in Hubei.

Ferritin, the cellular protein storage for iron, has emerged as a key molecule in the immune system, orchestrating the cellular defense against inflammation. At the end of 2019, the novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) rapidly spread throughout China and other countries around the world, resulting in a viral pandemic. ⋯ In this preliminary cross-sectional study, elevated ferritin levels were shown to correlate with disease severity in 39 patients from Israel with confirmed COVID-19 infection. Our results further strengthen the hypothesis that severe COVID-19 disease might be due to an underlying dysregulated hyperimmune response. In order to identify these patients early and prioritized resources, we believe that all patients with COVID-19 should be screened for hyperferritinemia.

ReviewConsiderations for Heart Failure Care During the COVID-19 Pandemic.
The coronavirus-2019 (COVID-19) infection pandemic has affected the care of patients with heart failure (HF) who have contracted COVID-19 as well as those without COVID-19 who have been impacted by the restructuring of health care delivery. Patients with HF and other cardiovascular comorbidities are at risk for severe disease and complications of infection. ⋯ During this pandemic, special considerations are needed for patients with advanced HF, including those supported by durable left ventricular assist devices (LVADs) and heart transplant recipients. The purpose of this review is to summarize emerging data regarding the development of HF secondary to COVID-19 infection in patients with advanced HF and the implications of the pandemic for care of uninfected patients with HF.

Despite many reports on the characteristics of coronavirus disease 2019 (COVID-19) in Wuhan, China, relatively little is known about the transmission features of COVID-19 outside Wuhan, especially at the provincial level. ⋯ Lymphocyte percentage was a sign of severe COVID-19 in general but was not a good diagnostic index. Longer time from illness onset to diagnosis was associated with higher COVID-19 severity, older age, higher likelihood of having coexisting cardiovascular diseases including hypertension, and being male. Farming was found to be a high-risk occupation in Henan province, China.
