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.

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.

New approach holds incredible potential for developing new therapeutics

Nearly every drug that is, or has ever been, used was derived from nature -- harnessing compounds created by organisms over eons to fight diseases. But decades ago, biochemists postulated that it might be possible to design a new drug from scratch by linking up amino acids in precise ways.

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.

Recommendations for hospitals to provide equitable care during pandemic resource allocation

If some regions become hot spots and hospitals reach maximum capacity during the COVID-19 pandemic, hospitals have plans for how to decide who gets critical care resources, such as a bed in the intensive care unit or a respirator.

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.

'Mini-brains' can be infected by SARS-CoV-2 virus

A multidisciplinary team from two Johns Hopkins University institutions, including neurotoxicologists and virologists from the Bloomberg School of Public Health and infectious disease specialists from the school of medicine, has found that organoids (tiny tissue cultures made from human cells that simulate whole organs) known as "mini-brains" can be infected by the SARS-CoV-2 virus that causes COVID-19.

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).

New study will help primary care nurses better care for dementia patients

McLean Hospital's Brent P. Forester, MD, MSc, is heading a new study of a training model to help primary care nurses better care for patients with dementia.

Survey: 47% of people use technology to communicate with their healthcare providers

New research shows that 47 percent of people are using technology to communicate with their healthcare providers, and less than a quarter are having conversations with their providers about using health information technology (HIT).

Ghana's efforts to eliminate malaria at risk as economy improves

Ghana's efforts to eliminate malaria could be in jeopardy as its improved economy results in reduced external funding for fighting malaria, a study suggests.

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.

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.
