Researchers develop better way to determine safe drug doses for children

Determining safe yet effective drug dosages for children is an ongoing challenge for pharmaceutical companies and medical doctors alike. A new drug is usually first tested on adults, and results from these trials are used to select doses for pediatric trials. The underlying assumption is typically that children are like adults, just smaller, which often holds true, but may also overlook differences that arise from the fact that children's organs are still developing.

WHO lists additional COVID-19 vaccine for emergency use and issues interim policy recommendations

WHO today listed the Sinopharm COVID-19 vaccine for emergency use, giving the green light for this vaccine to be rolled out globally. The Sinopharm vaccine is produced by Beijing Bio-Institute of Biological Products Co Ltd, subsidiary of China National Biotec Group (CNBG).

Our immune systems blanket the SARS-CoV-2 spike protein with antibodies

The most complete picture yet is coming into focus of how antibodies produced in people who effectively fight off SARS-CoV-2 work to neutralize the part of the virus responsible for causing infection. In the journal Science, researchers at The University of Texas at Austin describe the finding, which represents good news for designing the next generation of vaccines to protect against variants of the virus or future emerging coronaviruses.

Speeding new treatments

A year into the COVID-19 pandemic, mass vaccinations have begun to raise the tantalizing prospect of herd immunity that eventually curtails or halts the spread of SARS-CoV-2. But what if herd immunity is never fully achieved - or if the mutating virus gives rise to hyper-virulent variants that diminish the benefits of vaccination?

Large collaboration creates cell atlas of COVID-19 pathology

Scientists from several hospitals and research centers have shown what happens in individual cells of patients who died of COVID-19. In a study published in Nature, the researchers describe how infected cells from multiple organs exhibited a range of molecular and genomic changes. They also saw signs of multiple, unsuccessful attempts by the lungs to repair themselves in response to respiratory failure, which is the leading cause of death in COVID-19 patients.

Hepatitis C drugs multiply effect of COVID-19 antiviral Remdesivir

When combined with drugs currently used to treat hepatitis C, the antiviral remdesivir is 10 times more effective in treating cells infected with SARS-CoV-2, the virus that causes COVID-19.

Published this week in Cell Reports, this finding - from Gaetano Montelione, a professor of chemistry and chemical biology at Rensselaer Polytechnic Institute, and his collaborators at the Icahn School of Medicine at Mount Sinai and the University of Texas at Austin - raises the potential for repurposing available drugs as COVID-19 antivirals in cases where a vaccine isn't practical or effective.

How COVID-19 impacted UK healthcare

Just one third of people in the UK managed to access the hospital care they needed at the peak of the first wave of the Covid-19 pandemic - according to new research from the University of East Anglia.

A new study published today looks at the extent to which people managed to access NHS healthcare in April 2020, and as lockdown restrictions eased.
