Covid-19 and hospital staff: many infections, but few re-infections

A study of healthcare workers shows they were three times more likely to become infected during the Covid-19 pandemic compared to the general population. Around one in five of workers who were infected were asymptomatic and unaware they had Covid-19. The study published in ERJ Open Research also shows that it was not only frontline staff who faced the higher risk, suggesting that there was…

Post-acute Covid: study explores risk of developing long term conditions

One in 7 (14%) adults with coronavirus infection developed at least one new condition that required medical care during the post-acute phase of illness, which is 5% higher than adults with no coronavirus infection in 2020, finds a US study published by The BMJ. The post-acute phase in this study started 21 days (or 3 weeks) after initial infection.

Covid-19 death toll: experts estimate 1 million excess deaths

Almost 1 million extra deaths relating to the Covid-19 pandemic occurred in 29 high income countries in 2020, finds a study published by The BMJ. Except for Norway, Denmark and New Zealand, all other countries examined had more deaths than expected in 2020, particularly in men. The five countries with the highest absolute number of excess deaths were the US, UK, Italy, Spain, and Poland.

New Covid-19 testing method gives results within one second

The Covid-19 pandemic made it clear technological innovations were urgently needed to detect, treat, and prevent the SARS-CoV-2 virus. A year and a half into this epidemic, waves of successive outbreaks and the dire need for new medical solutions — especially testing — continue to exist. In the Journal of Vacuum Science & Technology B, researchers from the University of Florida and…

Rapid Covid-19 test delivers results within 4 minutes with 90 percent accuracy

A low-cost, rapid diagnostic test for Covid-19 developed by Penn Medicine provides Covid-19 results within four minutes with 90 percent accuracy. A paper published this week in Matter details the fast and inexpensive diagnostic test, called RAPID 1.0 (Real-time Accurate Portable Impedimetric Detection prototype 1.0). Compared to existing methods for Covid-19 detection, RAPID is inexpensive and…

Covid-19: Delay in second vaccine dose may prevent deaths under certain conditions

Delaying the second dose of Covid-19 vaccines, at least for people aged under 65, could result in up to 20% lower mortality, but only under certain conditions, finds a US study published by The BMJ. These conditions include a one dose vaccine effectiveness (efficacy) of 80% or higher and vaccination rates of 0.1% to 0.3% of the population per day. If these conditions apply, the researchers say…

AI predicts daily ICU trajectory for critical Covid-19 patients

Researchers used AI to identify which daily changing clinical parameters best predict intervention responses in critically ill Covid-19 patients. The investigators used machine learning to predict which patients might get worse and not respond positively to being turned onto their front in intensive care units (ICUs) - a technique known as proning that is commonly used in this setting to improve…

Remdesivir: additional mechanism against Covid-19 discovered

When a cell is infected, SARS-CoV-2 not only causes the host cell to produce new virus particles. The virus also suppresses host cell defence mechanisms. The virus protein nsP3 plays a central role in this. Using structural analyses, researchers at Goethe University in cooperation with the Swiss Paul Scherrer Institute have now discovered that a decomposition product of the virostatic agent…

Rare blood clots after Oxford-AstraZeneca vaccine: study sheds more light

A large study from Denmark and Norway published by The BMJ sheds more light on the risk of rare blood clots in adults receiving their first dose of the Oxford-AstraZeneca Covid-19 vaccine. The findings show slightly increased rates of vein blood clots including clots in the veins of the brain, compared with expected rates in the general population. However, the researchers stress that the risk of…

Workflow automation solutions for mid-volume laboratories

Clinical diagnostics company Beckman Coulter announced the European launch of the DxA 5000 Fit, a workflow-automation solution designed to fit into medium-sized labs that run fewer than 5,000 tests a day. The clinical laboratory has gone through trial by fire in 2020, where total testing was 245% of baseline volumes, with ~55% being SARS-CoV-2 molecular tests. Despite vaccines, many industry…

'Airway-on-a-chip' to find new Covid-19 drugs

A collaboration spanning four research labs and hundreds of miles has used the organ-on-a-chip (Organ Chip) technology from the Wyss institute at Harvard Univesity to identify the antimalarial drug amodiaquine as a potent inhibitor of infection with SARS-CoV-2, the virus that causes Covid-19. The Organ Chip-based drug testing ecosystem established by the collaboration greatly streamlines the…

Covid-19: Why faster air exchange in buildings is not always beneficial

Vigorous and rapid air exchanges might not always be a good thing when it comes to addressing levels of coronavirus particles in a multiroom building, according to a new modeling study. The study suggests that, in a multiroom building, rapid air exchanges can spread the virus rapidly from the source room into other rooms at high concentrations. Particle levels spike in adjacent rooms within 30…

'Covid-19 atlas' uncovers differing immune responses in asymptomatic versus severe cases

The largest study of its kind in the UK has identified differences in the immune response to Covid-19 between people with no symptoms, compared to those suffering a more serious reaction to the virus. The research by Newcastle University and collaborators within the Human Cell Atlas initiative found raised levels of specific immune cells in asymptomatic people. They also showed people with more…

How SARS-CoV-2 reprograms human cells to their own benefit

Coronavirus researchers under Prof. Rolf Hilgenfeld of the University of Lübeck and Dr. Albrecht von Brunn of the Ludwig-Maximilians University of Munich discovered how SARS viruses enhance the production of viral proteins in infected cells, so that many new copies of the virus can be generated. Other coronaviruses apart from SARS-CoV and SARS-CoV-2 do not use this mechanism, thereby providing a…
