The infection of lung stem cells may determine SARS-CoV-2 pathogenicity

A group of researchers from Russia and France has demonstrated how stem cells in the lungs can be readily infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), leading to significant defects in their regeneration capacity and more severe coronavirus disease (COVID-19). Their manuscript is currently available on the preprint server bioRxiv.

Newly identified gene may have contributed to rapid evolution of COVID-19

An international team of researchers has identified a previously uncharacterized gene within the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) genome that may be important in understanding the origins and evolution of coronavirus disease 2019 (COVID-19).

New study pinpoints ideal antiviral targets within the SARS-CoV-2 viral cycle

A specific biophysical model for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) shows how potential drugs inhibiting both viral transcription and translation would be particularly effective against coronavirus disease (COVID-19). The model was developed by University of Minnesota researchers and described in their recent publication available on the bioRxiv preprint server.

Pinpointing SARS-CoV-2 origin with new predictive model

Researchers in the United States and Canada have developed a combination of predictive statistical models that could help guide decisions about which animal species should be prioritized for detecting the origin of novel potential zoonotic viruses such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Even natural products may pose potential risk to unborn child

Plant products ingested by pregnant women through their diet are broken down by the intestinal microbiota into chemical substances, some of which can cross the placental barrier and reach the fetus.

SARS-CoV-2 is uniquely adapted to infect humans

The novel coronavirus pandemic has sparked much debate on its origin, with some suggesting it may have been laboratory-grown. Previous studies, however, mentioned that it is zoonotic in nature, which means that the virus jumped from wild animals and found its way to humans.

Can Chlorpromazine help treat COVID-19?

A new research paper published in the journal L'Encéphale in May 2020 reports on the planned ReCoVery Study, which will examine the possibility of repurposing the antipsychotic drug chlorpromazine for the treatment of COVID-19.

Using Qigong to manage COVID-19 in older adults

A recent study published in The American Journal of Geriatric Psychiatry in May 2020 reports on the possible usefulness of the integrative practice called Qigong to prevent and manage COVID-19 in older adults.

Children with COVID-19 presenting with sudden severe lung disease

Even as the COVID-19 pandemic continues to seek out new victims, puzzling new presentations are further confusing the situation. A new study published online in The Lancet Rheumatology in May 2020 reports a case of severe COVID-19 in a child who rapidly developed acute respiratory distress symptoms without prior respiratory symptoms. This case should alert clinicians to consider this diagnosis in children as well.

How 'superspreaders' impact COVID-19

A new study published on the preprint server medRxiv in May 2020 reflects the need to rethink and selectively impose lockdown on some but not all social activities, in the light of the impact of superspreaders on disease transmission.

Capillary leakage important in COVID-19 respiratory distress

Now, a new study published on the preprint server medRxiv reports the pivotal role played by protein leakage through lung capillaries and promotes the use of serum albumin as a biomarker of disease progression and severity.

Teens develop septic shock due to COVID-19

Since the emergence of the novel coronavirus disease (COVID-19), most people who develop severe illness are older adults, those with underlying medical conditions, and those who are immunocompromised. Though children are mostly spared, some adolescents developed septic shock due to COVID-19, a new study has found.

Heparin may stop SARS-CoV-2 infecting host cells

Researchers at the University of Sheffield have developed a new assay that can be used to assess the attachment of viruses to host cells and to test potential inhibitors of viral infection.

New biomarkers to consider for SARS-CoV-2 vaccine

Researchers at the University of Melbourne have made new discoveries about how the immune system responds to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that could be important to consider in vaccine research.

Study shows cats can harbor SARS-CoV-2 without any symptoms

A recent paper from Spanish researchers at the Hospital Universitario San Pedro-CIBIR, available on the medRxiv* preprint server, suggests that cats may act as asymptomatic dispersers of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), even though viral transmission from animals to humans still seems highly unlikely.

Smokers at increased risk of severe COVID-19 according to a large population study

A new UK study available on the preprint server medRxiv screened 2.4 million users of a symptom reporting application during the coronavirus disease (COVID-19) pandemic, revealing that smokers are at higher risk of increased symptom burden and more prone to hospitalization.

Coronavirus tests the value of artificial intelligence in medicine

Dr. Albert Hsiao and his colleagues at the University of California-San Diego health system had been working for 18 months on an artificial intelligence program designed to help doctors identify pneumonia on a chest X-ray. When the coronavirus hit the United States, they decided to see what it could do.
