Health Research: Vitamin D does not reduce colds in asthma patients ♦ Myths about surrogacy ♦ Inflammation linked to weakened reward circuits in depression

Majority of car-pedestrian deaths happen to those in wheelchairs, often at intersections An investigation into how often wheelchair users are killed in car-pedestrian crashes finds they are a third more likely to die than non-wheelchair users; more than half of those deaths occur at intersections
Inflammation linked to weakened reward circuits in depression Persistent inflammation affects the brain in ways that are connected with stubborn symptoms of depression, such as anhedonia, the inability to experience pleasure. The findings bolster the case that the high-inflammation form of depression is distinct, and are guiding researchers' plans to test treatments tailored for it.
Vitamin D does not reduce colds in asthma a patients Vitamin D supplements do not reduce the number or severity of colds in asthma patients, according to a new study. The findings surprised the researchers who had previously published research showing a 40 percent reduction in asthma exacerbations in patients with a vitamin D deficiency who achieved normal levels of the vitamin with supplements. Because colds often trigger exacerbations, they hypothesized that vitamin D supplementation would reduce colds and cold severity.
Landmark report exposes myths about surrogacy in the United Kingdom It is a myth that a high proportion of potential parents from the UK go overseas if they need to use surrogacy, a new report concludes. The landmark report is the first of its kind, and provides an unprecedented insight into how surrogacy is practised in the UK, dispelling a number of pervasive myths that have informed recent debate on the issue.
