GlySure says its continuous glucose monitor worked well in a study involving post-surgical cardiac patients. The results corresponded well with concentrations measured in blood draws, and the researchers said the work shows the system can help chip away at the need for frequent sampling. What's more, they say, the in-hospital/ICU system is showing some utility now as a way to potentially spot hypoglycemic and hyperglycemic problems. Researchers will present the study details at the World Federation of Societies of Intensive and Critical Care, in Durban, South Africa. GlySure, launched in 2006, is based in England and employs about 30 people. Item
