A study to be published in The Lancet Infectious Diseases on World AIDS Day shows the extraordinary global genetic diversity of HIV and highlights just how big the challenge is to develop a vaccine to combat the global spread of HIV.

Vaccine vile and syringe

One of the most comprehensive studies of HIV around the world has revealed a map of the spread of subtypes of the virus across the world, revealing which strains are dominant in which country and region, and where new strains are emerging.

The systematic review and global survey, led by Dr Joris Hemelaar of the University of Oxford, analysed 383,519 samples from 116 countries spanning the period 1990-2015. It found that the greatest diversity of HIV was found in Central Africa, but it also showed that different variants of HIV prevail in different regions of the world. What is more, the distribution of HIV strains is evolving over time and recombinants are increasing and now account for nearly a quarter (22·8%) of all global HIV infections.

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.
