AI shortcuts could lead to misdiagnosis of Covid-19
University of Washington researchers have discovered that AI models—like humans—have a tendency to look for shortcuts. In the case of AI-assisted disease detection, these shortcuts could lead to diagnostic errors if deployed in clinical settings.

Mild COVID-19 induces lasting antibody protection
Months after recovering from mild cases of COVID-19, people still have immune cells in their body pumping out antibodies against the virus that causes COVID-19, according to a study from researchers at Washington University School of Medicine in St. Louis. Such cells could persist for a lifetime, churning out antibodies all the while.

Long Covid? There's an app for that
People with long Covid could be monitored with the aid of a ground-breaking mobile phone app and clinical website. The system has been developed to help NHS rehabilitation teams manage the large number of people suffering from the debilitating effects of the illness. Patients will also be able to use the app to track their recovery. The app will initially be available to patients in 27 NHS trusts…

AI with swarm intelligence to analyse medical data
Communities benefit from sharing knowledge and experience among their members. Following a similar principle - called “swarm learning” - an international research team has trained artificial intelligence algorithms to detect blood cancer, lung diseases and Covid-19 in data stored in a decentralized fashion. This approach has advantage over conventional methods since it inherently provides…

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.

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…
