Smoking is associated with significantly higher risk of developing type 2 diabetes, according to new research in China published in The Lancet Public Health.

The prevalence of diabetes has increased almost 10-fold in China since the early 1980s, with one in 10 adults in China now affected by diabetes. Although adiposity is the major modifiable risk factor for diabetes, other research in China suggests this can explain only about 50% of the increase in diabetes prevalence over recent decades, suggesting other lifestyle factors, including smoking, may play a role in the aetiology of diabetes. In recent decades, there has been a large increase in cigarette smoking in China, especially among men. About two thirds of Chinese men now smoke, consuming roughly 40% of the world’s cigarettes.

Researchers from the University of Oxford, UK, the Chinese Academy of Medical Sciences and Peking University have examined the association of smoking and smoking cessation with the risk of diabetes in a large, nationwide study of 500,000 adults from 10 areas (five urban and five rural) of China. The present study included only people with no history of diabetes at the baseline, whose health status was monitored for nine years through death and hospital admission records. During this time over 13,500 participants developed new-onset type 2 diabetes.

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.
