The Randomised Evaluation of COVID-19 Therapy (RECOVERY) trial has demonstrated that baricitinib, an anti-inflammatory treatment normally used to treat rheumatoid arthritis, reduces the risk of death when given to hospitalised patients with severe COVID-19.

The benefit was in addition to those of dexamethasone and tocilizumab, two other anti-inflammatory treatments which have previously been shown to reduce the risk of death in these patients.

The University of Oxford-led RECOVERY trial has been testing a range of potential treatments for patients admitted to hospital for COVID-19 since March 2020. Between February and December 2021, 4008 patients randomly allocated to usual care alone were compared with 4148 patients who were randomly allocated to usual care plus baricitinib. The dose of baricitinib tablets was 4mg once daily for 10 days (or until discharge from hospital if sooner). At randomisation, 95% of patients were receiving a corticosteroid such as dexamethasone, 23% were receiving tocilizumab, and 20% were receiving the anti-viral drug remdesivir. Two-thirds (68%) of patients were receiving oxygen and one quarter (27%) were receiving additional respiratory support.

New evidence for how our brains handle surprise

A new study from the Bruno Group is challenging our perceptions of how the different regions of the cerebral cortex function. A group of ‘quiet’ cells in the somatosensory cortex that rarely respond to touch have been found to react mainly to surprising circumstances. The results suggest their function is not necessarily driven by touch, but may indicate an important and previously unidentified role across all the major cortices.

Language learning difficulties in children linked to brain differences

A new study using MRI has revealed structural brain changes in children with developmental language disorder (DLD), a common but under-recognised difficulty in language learning. Children with DLD aged 10-15 showed reduced levels of myelin in areas of the brain associated with speaking and listening to others, and areas involved in learning new skills. This finding is a significant advance in our understanding of DLD and these brain differences may explain the poorer language outcomes in this group.

Night-time blood pressure assessment is found to be important in diagnosing hypertension

Around 15% of people aged 40-75 may have a form of undiagnosed high blood pressure (hypertension) that occurs only at night-time. Because they do not know about this, and therefore are not being treated for it, they are at a higher risk of cardiovascular disease such as stroke, heart failure, and even death, suggests new research from the University of Oxford published in the British Journal of General Practice.
