On 30th January 2020, an outbreak of atypical pneumonia caused by a novel betacoronavirus, named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was declared a public health emergency of international concern by the World Health Organization. For this reason, a detailed evolutionary analysis of SARS-CoV-2 strains currently circulating in different geographic regions of the world was performed. A compositional analysis as well as a Bayesian coalescent analysis of complete genome sequences of SARS-CoV-2 strains recently isolated in Europe, North America, South America, and Asia was performed. ⋯ A significant migration rate per genetic lineage per year from Europe to South America was also observed. The results of these studies revealed an increasing diversification of SARS-CoV-2 strains. High evolutionary rates and fast population growth characterizes the population dynamics of SARS-CoV-2 strains.

To evaluate the performance of the extracorporeal membrane oxygenation retrieval team at a high-volume extracorporeal membrane oxygenation center during the coronavirus disease 2019 pandemic. ⋯ Extracorporeal membrane oxygenation retrieval can rescue young, previously healthy patients with severe coronavirus disease 2019 in whom all the conventional respiratory measures have failed. Thrombotic and hemorrhagic complications are frequent in this cohort.

Understanding the consequence of COVID-19 on undergraduate medical education: Medical students' perspective.
The coronavirus disease 2019 pandemic has significantly influenced the normal operations of all human affairs on a global scale. Indeed, the pandemic has had a considerable impact on the delivery of medical education in the UK for both pre-clinical and clinical year students. In response to the escalating case fatality rate due to the pandemic, there has been widespread termination of clinical placements, face-to-face teaching sessions, and examinations that require a physical presence by UK medical schools. ⋯ Despite the resultant complications of the pandemic on medical education, these challenging times may present a serendipitous opportunity for medical students to cultivate the personal attributes expected of a doctor in the face of adversity. In light of the pandemic, there is scope to reconsider the effectiveness of current medical education and welcome innovative methods of delivering education whilst ensuring quality. The combination of recent telecommunication developments with current teaching methodologies may positively change the future landscape of medical education.

The novel coronavirus disease (COVID-19) has been declared a pandemic by the world health organization and to limit the spread of the disease, many countries in the world, including India, had enforced a lockdown. Despite no restriction over the platelet donation activities, plateletpheresis donors became apprehensive regarding the possible risk of spread of the COVID-19 during the platelet donation and in the hospital premises. Many of them started hesitating for platelet donations. ⋯ The donor organizations and plateletpheresis donors were informed about the steps to be taken by the blood center during the donation and necessary steps for the prevention of the possible spread of COVID-19. With the help of these measures, the confidence of the individual platelet donors and the donor organizations was restored in the blood center and regular plateletpheresis was continued. These measures may also be useful to other blood centers in the COVID-19 pandemic and this experience may be useful if a similar pandemic lockdown happens in the future.
