Sticky DNA webs may cause tissue damage associated with severe COVID-19 infections

Sticky webs of DNA released from immune cells known as neutrophils may cause much of the tissue damage associated with severe COVID-19 infections, according to two new studies published September 14 in the Journal of Experimental Medicine.

Are children more likely to be SARS-CoV-2 asymptomatic than adults?

he frequency of children carrying asymptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been suggested to be higher than among adults. It is also suggested that asymptomatic children enhance viral spread. A new study published in the journal JAMA Pediatrics in September 2020 explores the truth of this common belief.

Should a COVID-19 vaccine be mandatory for children?

As the search for a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine continues, with some candidate vaccines nearing the completion Phase III clinical trials, a trio of experts weighs in with some sound reasoning as to whether any future vaccine should be considered mandatory for children. The viewpoint article is published in the journal JAMA Pediatrics in September 2020.

COVID-19 pandemic affects delivery of cancer care and oncologists' wellbeing

Delays and cancellation of cancer treatments and other safety measures undertaken to minimise the risk of exposure to the coronavirus (COVID-19) have generated a huge backlog in oncology care and research.

Researchers identify microRNA molecules that could repress the replication of human coronaviruses

HSE University researchers have found microRNA molecules that are potentially capable of repressing the replication of human coronaviruses, including SARS-CoV-2.

Efforts to control COVID-19 could create a health time bomb in slum communities

Efforts to stem the impact of COVID-19 in low to middle income countries could be creating a health time bomb in their slum communities by deepening existing inequalities, according to an international team of health researchers led by the University of Warwick.

New poll highlights feelings of loneliness and isolation among older adults during COVID-19

Staying close to home and avoiding crowded places can help older adults reduce their risk of COVID-19. But a new national poll suggests it comes with a cost, especially for those with health challenges.

With no legal guardrails for patients, ambulances drive surprise medical billing

School librarian Amanda Brasfield bent over to grab her lunch from a small refrigerator and felt her heart begin to race. Even after lying on her office floor and closing her eyes, her heart kept pounding and fluttering in her chest.

Facing COVID-19 patients on ventilators down may cause nerve damage

Some people are more likely to experience severe coronavirus disease (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). These include the elderly, people who are obese and have underlying medical conditions, such as diabetes, obesity, heart disease, lung illness, and kidney disease, among others.

Single-molecule imaging of SARS-CoV-2 spikes on virus particles

Using single-molecule FRET analysis, a team of researchers has revealed how the different conformations of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein are interconnected. Figuring out the different conformations in real-time and which conformations antibodies prefer may help design effective vaccines and drugs. The research is published on the preprint server bioRxiv*.

Balancing COVID-19 risk with educational benefits in school reopening decisions

Now a new study by researchers at the Institute for Disease Modeling and published on the preprint server medRxiv* in September 2020 focuses on modeling the potential risk of COVID-19 for school students and staff if schools are re-opened in a range of scenarios. This could guide further research on the health and educational outcomes of school reopenings.

Susceptibility of domestic pigs to SARS-CoV-2

A recent study published on the preprint server bioRxiv sought to determine the susceptibility of domestic swine to SARS-CoV-2. Domestic swine is one of the most highly produced agricultural species that has the potential to impact public health significantly.

Potential sea animal reservoirs for coronaviruses?

The COVID-19 pandemic has focused, yet again, intense research interest on coronaviruses, due to the high toll the novel coronavirus SARS-CoV-2 has taken on human life, health, economic well-being, and social activity. A recent paper published on the server Preprints in September 2020 reviews what is known about this viral infection in water life.

Climatic changes may potentially impact COVID-19 pandemic

A recent epidemiological study by Princeton University researchers suggests that the severity of coronavirus disease 2019 (COVID-19) outbreak during the winter season depends on the susceptibility of the population to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-induced infection as well as the effectiveness of non-pharmaceutical control measures applied to control the virus spread.

New insights into structural stability of SARS-CoV-2 main protease

In a recent bioRxiv preprint paper, researchers from the US and Italy utilized molecular dynamics simulations and revealed that the conformational stability of the SARS-CoV-2 binding site, bound inhibitors, and the hydrogen bond networks of the viral main protease (Mpro) are highly sensitive to protonation assignments.

A map of SARS-CoV-2 escape mutations enables the development of therapeutic antibody cocktails

A recent tour-de-force study by the US researchers describes a comprehensive approach to completely map mutations to the SARS-CoV-2 receptor-binding domain (RBD) that escape antibody binding – enabling, in turn, rational design of antibody therapeutics and appraisal of the antigenic consequences of viral evolution. The results are currently available in a bioRxiv preprint paper.

Shedding light on altered blood cell traits involved in severe COVID-19

Researchers at the University of Georgia in the United States have shed light on the pathological mechanisms underlying the association between the genetic locus 3p21.31 and severe coronavirus disease 2019 (COVID-19).

India's whole-virion inactivated SARS-CoV-2 vaccine shows promise

Researchers in India have conducted a preclinical study demonstrating the safety and efficacy of a new candidate vaccine for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the agent that causes coronavirus disease 2019 (COVID-19).

Researchers develop highly scalable, accurate antibody test for COVID-19

An antibody test for the virus that causes COVID-19, developed by researchers at The University of Texas at Austin in collaboration with Houston Methodist and other institutions, is more accurate and can handle a much larger number of donor samples at lower overall cost than standard antibody tests currently in use.
