SARS-CoV-2 (Severe acute respiratory syndrome coronavirus-2) is evolving with the progression of the pandemic. This study was aimed to investigate the diversity and evolution of the coronavirus SARS-CoV-2 with progression of the pandemic over time and to identify similarities and differences of viral diversity and evolution across geographical regions (countries). ⋯ SARS-CoV-2 belonging to the A2a type possesses a non-synomymous variant (D614G) that possibly eases the entry of the virus into the lung cells of the host. This may be the reason why the A2a type has an advantage to infect and survive and as a result has rapidly swept all geographical regions. Therefore, large-scale sequencing of coronavirus genomes and, as required, of host genomes should be undertaken in India to identify regional and ethnic variation in viral composition and its interaction with host genomes. Further, careful collection of clinical and immunological data of the host can provide deep learning in relation to infection and transmission of the types of coronavirus genomes.

The coronavirus disease-2019 outbreak has spread rapidly affecting 1.4 million people across the world in only four months. Healthcare fraternity is struggling to circumvent the consequences of this fast spreading infection and communicating their scientific discoveries through research publications. ⋯ This paper discusses these potential risks posed by deceptive (predatory) journals, for prospective authors and scientific community, during the COVID-19 outbreak. It also presents ways to address those risks and the role of journal editors and academic organisations.

The Covid-19 pandemic has concentrated bioethics attention on the "lifeboat ethics" of rationing and fair allocation of scarce medical resources, such as testing, intensive care unit beds, and ventilators. This focus drives ethics resources away from persistent and systemic problems-in particular, the structural injustices that give rise to health disparities affecting disadvantaged communities of color. Bioethics, long allied with academic medicine and highly attentive to individual decision-making, has largely neglected its responsibility to address these difficult "upstream" issues. It is time to broaden our teaching, research, and practice to match the breadth of the field in order to help address these significant societal inequities and unmet health needs.

Anticoagulant treatment is associated with decreased mortality in severe coronavirus disease 2019 patients with coagulopathy.
A relatively high mortality of severe coronavirus disease 2019 (COVID-19) is worrying, and the application of heparin in COVID-19 has been recommended by some expert consensus because of the risk of disseminated intravascular coagulation and venous thromboembolism. However, its efficacy remains to be validated. ⋯ Anticoagulant therapy mainly with low molecular weight heparin appears to be associated with better prognosis in severe COVID-19 patients meeting SIC criteria or with markedly elevated D-dimer.
