A systematic review and meta-analysis of stroke in COVID-19 patients

Fourteen out of every 1,000 COVID-19 patients admitted to hospital experience a stroke, a rate that is even higher in older patients and those with severe infection and pre-existing vascular conditions, according to a report published this week.

Deep learning models help hunt for COVID-19 drugs

Michigan State University Foundation Professor Guowei Wei wasn't preparing machine learning techniques for a global health crisis. Still, when one broke out, he and his team were ready to help.

Cognitive disorders associated with risk for developing severe COVID-19

Dementia and other cognitive disorders now appear to be risk factors for developing severe COVID-19, according to research from the University of Georgia. The findings highlight the need for special care for populations with these preexisting conditions during the pandemic.

Study of SARS-CoV-2 outbreak in meat processing plant suggests aerosol transmission in confined places

The importance of maintaining high-quality air flow to restrict transmission of SARS-CoV-2 in confined workspaces has been strongly indicated by the investigation of an outbreak of the virus at a German meat processing plant during May and June 2020.

Research finds a problem with concept of herd immunity in COVID-19

A recent study published on the preprint server medRxiv* in October 2020 suggests that arguments in favor of herd immunity are weakened by the fact that the steep increase in the number of COVID-19 deaths as a result of being exposed to the virus many times instead of once or a few times is not taken.

Scientists compare ACE2 interaction with SARS-CoV-2 across species

Like other pathogenic coronaviruses, SARS-CoV-2 crossed the species barrier to cause human disease. This fact motivated the current study, published on the preprint server bioRxiv* in October 2020, which explores the way coronaviruses engage their host cell receptors in a range of animals.

Structure and mechanisms of ribosomal frameshifting during SARS-CoV-2 translation

The structure of a 3’ stimulatory pseudoknot in the viral genome or by itself has been proposed recently. Researchers report the structure and mechanisms of mammalian ribosomes during translation of the -1 frameshifting of the SARS-CoV-2 viral genome in a new study published on the preprint server bioRxiv.

Scientists design 3D map to understand the behavior of novel coronavirus

To better understand how the novel coronavirus behaves and how it can be stopped, scientists have completed a three-dimensional map that reveals the location of every atom in an enzyme molecule critical to SARS-CoV-2 reproduction.

Study: Coronaviruses are adept at imitating human immune proteins involved in COVID-19

Coronaviruses are adept at imitating human immune proteins that have been implicated in severe COVID-19 disease, a study from researchers at Columbia University Vagelos College of Physicians and Surgeons has found.

Study shows potential impacts of robots in medical diagnosis and delivery

Emergency intubation in the field is a challenge for everyone involved, most especially the patient. Paramedics and EMTs have to contend with less than ideal circumstances while they attempt to insert a stiff laryngoscope down the throat and into the lungs of a nonresponsive patient.

Mathematical model for COVID-19 allows for dynamic social distancing and relaxation

Recently, researchers from York University, Toronto, Canada, presented a mathematical model for COVID-19 comprising groups of people with various levels of exposure to the disease based on data from Ontario, Canada. Their work is published on the preprint server medRxiv.

Furin cleavage site and D614G on SARS-CoV-2 spike evolved to balance infectivity, stability, cytopathicity

SARS-CoV-2 is the causative agent of COVID-19 disease, currently raging across the world. The virus has now infected more than 43.89 million individuals and claimed over 1.16 million lives. The study titled, "Spike glycoprotein and host cell determinants of SARS-CoV-2 entry and cytopathic effects," is released on the preprint server bioRxiv* in October 2020.

Gut's immune response to SARS-CoV-2 very different from the lung

Megan L. Stanifer et al. study the immune response in the human gut upon SARS-CoV-2 infection. The study published as a bioRxiv* preprint reveals a robust proinflammatory response: a cell type-specific or a tissue-specific regulation of interferon-mediated signaling during SARS-CoV-2 infection.

COVID vaccine misinformation lowering people's intent to get vaccinated

A new study by researchers at the Imperial College London and the London School of Hygiene and Tropical Medicine aimed to determine how online misinformation impacts COVID-19 vaccine uptake intent. Further, the team wanted to identify socioeconomic groups at a higher risk of not getting vaccinated and those who are most susceptible to online misinformation.

Inflammasome may play a key role in triggering immune response to cancer

The inflammasome — a protein signaling network that is activated to rid the body of virus or bacteria-infected cells — may play an important role in triggering an immune response to cancer and causing an existing class of drugs to work better against cancers.

Study findings could lead to a rapid, cost-effective screening tool for COVID-19

A new study from Lawson Health Research Institute, Western University and University of Alberta suggests that COVID-19 affects the human body's blood concentration levels of specific metabolites - small molecules broken down in the human body through the process of metabolism.

Bigger households associated with greater odds of SARS-CoV-2 transmission

Household transmission plays a pivotal role in the spread of SARS-CoV-2. The study recommends that it is essential for people to get tested immediately or as soon as symptoms appear. This way, they will take precautions to protect the other members of the family.

DNase coated melanin-like nanospheres for sepsis treatment in severe COVID

As the treatment of severe COVID-19 is very difficult, the researchers from the Korea Research Institute of Biosciences and Biotechnology (KRIBB) suggested that DNase-1 can be utilized to dissolve the neutrophil extracellular traps (NETs), hence halting the further progression of COVID-19.

Rapid CD169 assay for COVID-19 screening

Researchers in France have conducted a study demonstrating the sensitivity of a rapid flow cytometry assay that could be used to screen for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

Research examines COVID-19 transmission patterns in Georgia, U.S.

Researchers from Emory University and the Georgia Department of Public Health have shown that the transmission of coronavirus disease 2019 (COVID-19) in the state of Georgia earlier this year changed over time and varied by age.
