Early tracheostomy could reduce recovery time in critical COVID-19, say researchers

A new study by researchers at the Northwestern University Feinberg School of Medicine, USA, reports the findings of a study on the safety of tracheostomy of critically ill patients and the feasibility of decannulation in most survivors. The researchers view this as a means to improve care in these patients

Study explores individual differences of SARS-CoV-2 infection in ACE2-expressing stem cells

The clinical phenotype of COVID-19, caused by SARS-CoV-2, is remarkable for its wide range of severity among individual patients. Genetic variations are known to mediate part of these differences. To examine these differences, researchers in a new study used human induced pluripotent stem cells (iPSCs) from different genetically diverse individuals. These cells are used to model genetic disease since they contain the donor’s genetic information. Researchers use a panel of iPSCs from over 500 individuals. The researchers preferred undifferentiated iPSCs to reduce the time required to differentiate them, especially since infection is not always reliable.

Influenza A virus defective interfering particles against SARS-CoV-2

In the search for a broadly acting pan-specific antiviral, an interdisciplinary team from Germany tested the previously proposed (for antiviral treatment against Influenza A infections) - Influenza A virus (IAV) defective interfering particles (DIPs). The research is published online on the bioRxiv preprint server.

FDA-approved heart drug shows potential for treatment of SARS-CoV-2

A federally approved heart medication shows significant effectiveness in interfering with SARS-CoV-2 entry into the human cell host, according to a new study by a research team from Texas A&M University and The University of Texas Medical Branch.

Some nutritional supplements may help prevent or mitigate COVID-19 severity

A new study in the Journal of dietary supplements shows that nutritional supplements, including several vitamins and the mineral zinc, may be useful in preventing the infection or reducing its severity if caught.

Organ transplant patient dies after receiving Covid-infected lungs

Doctors say a woman in Michigan contracted covid-19 and died last fall two months after receiving a tainted double-lung transplant from a donor who turned out to harbor the virus that causes the disease — despite showing no signs of illness and initially testing negative.

Chicken-derived antibody shows potent neutralizing capacity against SARS-CoV-2 in vitro

Researchers report on a Chicken-derived antibody against SARS-CoV-2, offering preliminary data on a potential therapeutic for COVID-19 warranting further research.

Research shows rapid global spread of Southern California COVID-19 strain

A new strain of the coronavirus in Southern California, first reported last month by Cedars-Sinai, is rapidly spreading across the country and around the world as travelers apparently carry the virus with them to a growing list of global destinations, according to new research published today in the peer-reviewed Journal of the American Medical Association.

SARS-CoV-2's resistance to remdesivir in vitro

A new preprint research paper posted to the bioRxiv server discusses the emergence of mutations in the SARS-CoV-2 virus, allowing it to escape the effects of the most commonly used antiviral drug, remdesivir.

SARS-CoV-2 evolves antibody resistance in immunocompromised patient

Researchers in the United States who tracked the evolution of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in an immunocompromised patient found that convalescent plasma therapy was associated with the emergence of viral variants that were less susceptible to neutralizing antibodies.

Scientists make four major discoveries about SARS-CoV-2

University of Minnesota Medical School researchers studied SARS-CoV-2 infections at individual cellular levels and made four major discoveries about the virus, including one that validates the effectiveness of remdesivir - an FDA-approved antiviral drug - as a form of treatment for severe COVID-19 disease.

A precursor to remdesivir shows therapeutic potential for COVID-19

A new study points to the potential to use the remdesivir precursor, GS-441524, as a treatment choice for COVID-19.

Can early use of colchicine reduce COVID-19 mortality?

The COVID-19 pandemic, caused by SARS-CoV-2, has caused well over 2.3 million deaths in a little over a year. A new meta-analysis reports the potential utility of colchicine in treating SARS-CoV-2 infection and forestalling severe and life-threatening inflammation of the lungs and other organs.

Visualization of SARS-CoV-2 RNA by fluorescence in situ hybridization probes

A team of scientists from France has recently designed fluorescence in situ hybridization probes (CoronaFISH) to visualize severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA in infected cells. A detailed description of the probe design, validation, and application is currently available on the bioRxiv preprint server.

New SARS-Cov-2 mutations could arise during chronic infection, say scientists

SARS-CoV-2 mutations similar to those in the B1.1.7 UK variant could arise in cases of chronic infection, where treatment over an extended period can provide the virus multiple opportunities to evolve, say scientists.

Alzheimer's risk gene can increase COVID-19 susceptibility and severity

A City of Hope-led research team found that the same gene that increases the risk for Alzheimer's disease, ApoE4, can increase the susceptibility to and severity of COVID-19.

Oxysterol derivatives show powerful antiviral activity against SARS-CoV-2 in vitro

A new study describes the antiviral activity of oxysterols, or oxidized cholesterol derivatives, against SARS-CoV-2. These occur in nature, and are not only involved in lipid signaling pathways that modulate a host of processes within the body, including the immune response and lipid homeostasis.

Study could help understand mechanisms of drug molecules to mitigate COVID-19 infection

As the scientific community continues researching the novel coronavirus, experts are developing new drugs and repurposing existing ones in hopes of identifying promising candidates for treating symptoms of COVID-19.
