A quarter of COVID-19 survivors had impaired lung function 1 year after infection, and older patients, those with more than three chronic conditions, and those with severe cases improved slower than other patients over time, a Dutch study published yesterday in PLOS One reveals.
...in Heart, researchers from Amsterdam University Medical Centers reportthat elite athletes followed up for 2 years after COVID-19 infections suffered no lasting damage to their hearts and faced no career setbacks because of their illnesses.
A recent UK study suggests that blood clots in the brain or lungs may explain some of the common symptoms experienced by people with "long Covid", including brain fog and fatigue. The study, which included 1,837 people admitted to hospital due to Covid, found that two blood proteins, fibrinogen and D-dimer, were associated with cognitive problems. It is estimated that 16% of these patients experience difficulties with thinking, concentrating, or remembering for at least six months.
Two more lab groups—one from Sweden's Karolinska Institute and the other from Harvard University—have reported results of antibody neutralization lab experiments, which suggest vaccination or previous infection offer some protection against the highly mutated BA.2.86 SARS-CoV-2 variant.
Two teams of US scientists have completed lab experiments testing the antibodies from vaccinated and infected Americans to see how well they might be able to fend off currently circulating variants of the virus that causes Covid-19, including the highly mutated BA.2.86.
