[Editorial] COVID-19 and China: lessons and the way forward

The Lancet - Sa, 25/07/2020 - 00:00
China has largely controlled COVID-19. A country of 1·4 billion people and a size similar to Europe or the USA now reports only clusters of cases rather than widespread community transmission. China has been widely criticised for its role and responsibilities during the pandemic because of censorship, transparency, and human rights concerns. But the rest of the world can still learn from China's successes in bringing its outbreak under control.

[Comment] Tapering glucocorticoids in rheumatoid arthritis

The Lancet - Sa, 25/07/2020 - 00:00
Glucocorticoids are a cornerstone of care for patients with rheumatoid arthritis. Since the 1950s, glucocorticoids have been used to reduce inflammation and symptoms of arthritis, improve physical function, and reduce disability. These drugs are widely available, inexpensive, and typically combined with disease-modifying antirheumatic drugs to induce remission in rheumatoid arthritis. However, the administration of glucocorticoids is not without risk. Long-term use of glucocorticoids is associated with increased mortality,1 cardiovascular events,2 and bone fractures.
