BMI should be assessed in management of COVID-19 patients

A new study published on the preprint server medRxiv* in June 2020 reports that obesity is a risk factor of composite poor outcome of COVID-19 disease. On the other hand, COVID-19 patients with 'composite poor outcome' have higher BMI. Therefore, BMI should be assessed in the management of COVID-19 patients, and special attention should be given to patients with obesity.

SARS-CoV-2 circulating in Brazil back in November 2019

The finding, published on the preprint server medRxiv in June 2020, shows that it has been causing infection in Brazil long before the first case was reported in the Americas, North and South, in January 2020, and certainly before the first case in this Brazilian region.

Silk useful as face mask and PPE in COVID-19

As many people are resorting to face coverings improvised from common fabrics, researchers from the University of Cincinnati looked to determine what fabrics were the most effective. The team examined the hydrophobicity of fabrics (silk, cotton, polyester), as measured by their resistance to the penetration of small and aerosolized water droplets, an important transmission avenue for the virus causing COVID-19.

Oral hygiene and severity of COVID-19 – the connection

Their study titled, “Could there be a link between oral hygiene and the severity of SARS-CoV-2 infections?” was published in the latest issue of the journal British Dental Journal.

Herd immunity in the U.S. unlikely

The race to develop an effective vaccine against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is on, with many vaccine candidates entering the human trial phase. When a vaccine is developed and introduced into the population at scale, it triggers herd immunity, with many people immune to the infectious disease.

New swine flu strain with pandemic potential found in China

As the world grapples with a novel coronavirus pandemic, a new strain of swine flu that can trigger a pandemic has been reported.

Striking CryoEM image of SARS-CoV-2

A new study by researchers from the UK and Germany and published on the preprint server bioRxiv in June 2020 reports the results of a detailed study of the S protein on the intact virus, using cryoelectron microscopy (cryoEM) and tomography. This could help understand the conformation of the S protein on the virion and how it interacts with neutralizing antibodies.

Large-scale analysis of COVID-19 risk among different groups of UK hospital staff

Staff who shared a household with an infected person were at the greatest risk of infection, and those working in COVID-19-facing areas were also at an increased risk. Other groups that were identified as a high risk included Black and Asian individuals, porters, and cleaners.

Specific SARS-CoV-2 genetic elements found in different insect species

In a recent bioRxiv paper, researchers from Norway and the US demonstrate the presence of a highly conserved, mobile genetic element (thus far with unknown function) in genomes of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and a large number of insects – opening the door for hitherto unexplored treatment opportunities.

Potential new biomarker could improve COVID-19 diagnosis

Researchers at Montpellier University Hospital have discovered that an interferon-inducible receptor expressed on monocytes could be a useful biomarker for the rapid triaging of patients suspected to have severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

SARS-CoV-2 can infect heart cells in a lab dish, study shows

A new study shows that SARS-CoV-2, the virus that causes COVID-19 (coronavirus), can infect heart cells in a lab dish, indicating it may be possible for heart cells in COVID-19 patients to be directly infected by the virus.

COVID-19 patients' blood can help identify people at greatest risk of severe illness

Doctors can examine COVID-19 patients' blood to identify those at greatest risk of severe illness and to pinpoint those most likely to need a ventilator, new research from the University of Virginia School of Medicine suggests.

Foldable tent-like device shields healthcare workers caring for COVID-19 patients

A team of researchers from the National University of Singapore has invented a foldable tent-like device that serves as a physical shield to reduce the risk of exposure to pathogens for healthcare workers performing droplet and aerosol-generating procedures on COVID-19 patients.

COVID-19 triggers changes in blood platelets

Changes in blood platelets triggered by COVID-19 could contribute to the onset of heart attacks, strokes, and other serious complications in some patients who have the disease, according to University of Utah Health scientists.

Salk Institute expands research to find treatments and cures for COVID-19

As the COVID-19 pandemic continues across the globe, the Salk Institute joins in efforts to understand the fundamental science behind the novel coronavirus to pave the way to treatments and cures.

Spike protein and human ACE2 binding ability shows SARS-CoV-2 viral adaptation

A new study published on the preprint server bioRxiv in June 2020 reports some important findings that could shed light on this question. As the pandemic marches on, having claimed over 500,000 lives and caused well over 10 million infections to date, the task of defining and predicting factors that predispose to infectivity across species becomes ever more critical.

Researchers search for SARS-CoV-2 fomites on an operational Italian bus

A new study reports the results of a viral detection study carried out in buses used for public transport across the final week of lockdown, as travel restrictions were being lifted step by step. This study by Italian researchers and published on the preprint server bioRxiv* in June 2020, may help to understand how a virus can spread within a city bus during normal operation and how effective are the measures used to protect against such transmission.

Study: Even the sickest COVID-19 patients produce T cells that help fight the virus

A new study from researchers at La Jolla Institute for Immunology (LJI) and Erasmus University Medical Center (Erasmus MC) shows that even the sickest COVID-19 patients produce T cells that help fight the virus.

Identification of SARS-CoV-2 RNA in healthcare HVAC units

Now, a new study published on the preprint server medRxiv* in June 2020 reports that viral RNA has been found to occur in HVAC (Heating, Ventilation, and AC) units in healthcare facilities. However, it is not clear if this represents a possible mechanism of viral transmission.

Modified Vaccinia Ankara-based vaccine candidate for SARS-CoV-2

Now, a new study by researchers at Emory University, the University of Texas Medical Branch and the Ragon Institute and published on the preprint server bioRxiv in June 2020 reports the development of a promising new vaccine candidate that may rapidly and effectively induce the production of neutralizing antibodies against the spike protein of the virus.
