Health Check

We learn about a new injectable microgel to help reduce bleeding in infants who require surgical care. In a mice model, it reduced bleeding by at least 50%. Ashley Brown, Professor of Biomedical Engineering at North Carolina State University and UNC Chapel Hill tells presenter Claudia Hammond more about this new material her team has designed.Joined by Professor of Global Health and Epidemiology at Boston University in the US, Dr Matthew Fox, Claudia hears about a mystery illness that is being investigated by health officials in Burundi, which has caused five deaths and sickened thirty-five people. So far lab analysis of the illness - which causes fever, vomiting, and diarrhoea - has been negative for Ebola and Marburg viruses, Rift Valley fever, and others.We hear about influential analysis from Cochrane which has concluded that "breakthrough" Alzheimer's drugs are unlikely to benefit patients. Researchers said the impact was "well below" what was needed to make a difference to dementia patients' lives. Howe
