ReviewSevere respiratory SARS-CoV2 infection: Does ACE2 receptor matter?
SARS-CoV-2 is a novel virus of the Coronaviridiae family that represents a major global health issue. Mechanisms implicated in virus/host cells interaction are central for cell infection and replication that in turn lead to disease onset and local damage. ⋯ Molecular mechanisms that promote interaction between SARS-CoV-2 virus and host with particular focus on virus cell entry receptor ACE2 are described. We further explore the impact of underlying medical conditions and therapies including renin-angiotensin inhibitors on modulating ACE 2, which is the major SARS-CoV-2 cell entry receptor.

According to the World Health Organization (WHO) the China office was first notified of cases of atypical pneumonia in Wuhan City on 31 December 2019. A viral genome sequence of a novel coronavirus, currently termed SARS-CoV‑2, with a disease process called COVID-19 was released 1 week later via online resources to obtain public health support in control of spread. Since then, the virus rapidly evolved into a global pandemic. ⋯ Currently, treatment is supportive. Researchers are working to develop vaccines and identify effective antiviral interventions. Those recently discussed in the literature are briefly reviewed.

Facing a disruptive threat: how can a nuclear medicine service be prepared for the coronavirus outbreak 2020?
The aim of this short communication is to outline our experience in policies and processes of a nuclear medicine service during the COVID-19 outbreak in Singapore. ⋯ Since our hospital received the first patient with COVID-19 in Singapore, our centre has managed 16 COVID-19 cases to date. There has not been any healthcare worker in our institution who has contracted COVID-19 through patient contact. We have highlighted for discussion some of the policies and processes to prepare a nuclear medicine service for the COVID-19 threat.

Meta AnalysisAssociation of inflammatory markers with the severity of COVID-19: A meta-analysis.
Studies reported associations of inflammatory markers with the severity of COVID-19, but conclusions were inconsistent. We aimed to provide an overview of the association of inflammatory markers with the severity of COVID-19. ⋯ The meta-analysis highlights the association of inflammatory markers with the severity of COVID-19. Measurement of inflammatory markers might assist clinicians to monitor and evaluate the severity and prognosis of COVID-19.

ReviewThe role of host genetics in the immune response to SARS-CoV-2 and COVID-19 susceptibility and severity.
This article provides a review of studies evaluating the role of host (and viral) genetics (including variation in HLA genes) in the immune response to coronaviruses, as well as the clinical outcome of coronavirus-mediated disease. The initial sections focus on seasonal coronaviruses, SARS-CoV, and MERS-CoV. We then examine the state of the knowledge regarding genetic polymorphisms and SARS-CoV-2 and COVID-19. The article concludes by discussing research areas with current knowledge gaps and proposes several avenues for future scientific exploration in order to develop new insights into the immunology of SARS-CoV-2.
