Brain damage is not caused by direct COVID-19 attack, indicates study

n an in-depth study of how COVID-19 affects a patient's brain, National Institutes of Health researchers consistently spotted hallmarks of damage caused by thinning and leaky brain blood vessels in tissue samples from patients who died shortly after contracting the disease.

Older adults, minorities and people with lower incomes face inequities in telemedicine use

After "COVID-19," the term that most people will remember best from 2020 is likely to be "social distancing." While it most commonly applied to social gatherings with family and friends, it has impacted the way many receive medical care.

Study offers explanation for silent hypoxemia in COVID-19 patients

One of the physiopathological characteristics of COVID-19 that has most baffled the scientific and medical community is what is known as "silent hypoxemia" or "happy hypoxia".

New, rapid antibody test gives detailed information on how the immune system reacts to Covid-19

A new type of antibody test is being developed by researchers at Linnaeus University and the bioanalysis company Attana. Compared to the binary antibody tests used today, this rapid test can give more detailed information on how our immune systems react to Covid-19 and other types of viruses and bacteria.

Live free or die if you must, say Colorado urbanites — but not in my hospital

Whenever Larry Kelderman looks up from the car he's fixing and peers across the street, he's looking across a border. His town of 28,000 straddles two counties, separated by County Line Road.

In fast-moving pandemic, health officials try to change minds at warp speed

Nine months into the pandemic that has killed more than 320,000 people in the U.S., Kim Larson is still trying to convince others in her northern Montana county that COVID-19 is dangerous.

Model to assess the effect of lockdowns has fundamental shortcomings

In a recent study, researchers from Imperial College London developed a model to assess the effect of different measures used to curb the spread of the coronavirus.

Popular glucose-lowering drug may cause rare diabetes complication in COVID-19 patients

Diabetes is a known risk factor for morbidity and mortality related to COVID-19. In diabetes patients, rare but severe complications, like the potentially lethal condition diabetic ketoacidosis (DKA), can arise when illness or certain conditions prevent cells from receiving enough glucose to fuel their functioning.

Researchers develop new system for direct detection of SARS-CoV-2 in aerosols

Researchers from the Polytechnic University of Valencia, in collaboration with specialists from the University of Valencia (UV), have come up with a new system based on a high-sensitivity mass biosensor that continuously monitors signals for the direct detection of SARS-CoV-2 in environmental aerosols.

Severity of COVID-19 correlates with the ratio of antibodies targeting crucial viral protein

COVID-19 antibodies preferentially target a different part of the virus in mild cases of COVID-19 than they do in severe cases, and wane significantly within several months of infection, according to a new study by researchers at Stanford Medicine.

SARS-CoV-2 spike-antibody binding strength and hydrogen bond numbers are temperature dependent, study finds

A new preprint on the bioRxiv* server describes the interactions between the binding spike protein of the SARS-CoV-2 virus with the antibodies. Earlier studies have addressed the similarity in the 3D structures of the spike protein in the two SARS viruses as seen on cryo-EM.

24 Dec 2020

Could engineered red blood cells be an effective antiviral against SARS-CoV-2?

In a new study, released on the bioRxiv* preprint server, a team of researchers explores the antiviral potential of red blood cells against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative pathogen of COVID-19.

Animal study suggests palmitoylation inhibitor reduces virulence of SARS-CoV-2

A new study preprint on the bioRxiv* server demonstrates the ability of a fatty acid synthase inhibitor to improve the survival of mice infected with murine hepatitis virus. In so doing, it adds to the sum of knowledge about the relationship of SARS-CoV-2 with cholesterol metabolism in the host cell.

Anti-SARS-CoV-2 NTD-directed antibodies are protective against lethal infection

As the world struggles to contain the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), responsible for over 1.6 million deaths and 76 million infections globally, researchers are trying to pin down the determinants of lethality, of infectivity and of protection. Such data would help contain its spread and develop preventive and therapeutic antivirals and vaccines. A new preprint that appeared recently on the bioRxiv* server describes the high degree of protection afforded by antibodies that target the N-terminal domain (NTD) of the virus.

Immunologic modeling of COVID-19 severity and chronicity

In a new study by researchers at Universidad de Costa Rica and other institutions, a bioinformatics approach is used to determine whether Chronic COVID-19 (CC) might have a distinct immunologic signature compared to the mild to moderate (MM) or the severe/critical COVID-19.

24 Dec 2020

Loss of taste and smell may be most reliable COVID-19 symptoms for digital surveillance

A team of researchers from various institutions in London, Israel, and the USA recently tested the existence of consistent links between COVID-19 symptoms and SARS-CoV-2 test status in 3 national surveillance platforms.
