Many usage guides have disparaged preventative as improper, because it doesn't accord with classical roots: the Latin past participle stem praevent- adds -ion to form prevention and -ive to form preventive. Words ending in -ative ought to have the -at- in the root already: demonstrat- begets demonstration and demonstrative, narrat- begets narration and narrative, and so forth. Since we don't have preventation, then preventative is equally misbegotten, by this way of thinking.
The NIH National Institute of Diabetes and Digestive Diseases and Kidney Diseases says it, “currently supports studies that are working toward obtaining FDA licensure to reclassify islet allo-transplantation as therapeutic. In other countries, such as Canada and Scandinavia, islet allo-transplantation is no longer considered experimental and is an accepted therapy in certain patients.” It adds that “Some patient advocates and islet researchers feel that islet allo-transplantation is close to having a therapeutic label.”
Also known as smart insulin, Professor John Fossey at the University of Birmingham is developing this type of insulin delivery system which is designed to circulate in the body, inactive, until blood glucose levels start to rise. As they do, the insulin goes to work to bring these levels back down, ensuring perfect glucose control throughout any given day.
Type 2 diabetes: Type 2 diabetes affects the way the body uses insulin. While the body still makes insulin, unlike in type I, the cells in the body do not respond to it as effectively as they once did. This is the most common type of diabetes, according to the National Institute of Diabetes and Digestive and Kidney Diseases, and it has strong links with obesity.
