This medical-grade polyester is currently used in teeth guards that kids and adults wear at night, in tiny tubes used to guide the growth of damaged nerve fibers and in surgical sutures. Researchers are also looking at PCL’s potential as an implant to deliver medications directly to the eyes and to tumors and as a scaffold for growing human tissue. PCL may be an ideal package for islet cells, the studies note, because it can be used to create thin, flexible membranes with pores that let in glucose and nutrients, let out insulin and exclude bigger immune-system molecules.
One of the most advanced alternatives comes from the Diabetes Research Institute (DRI) in the US, which is developing a bioengineered mini-organ where insulin-producing cells are encapsulated within a protective barrier. Two years ago, the DRI announced that the first patient treated in an ongoing Phase I/II trial no longer requires insulin therapy.
But as I write in my forthcoming book, The Good Neighbor: The Life and Work of Fred Rogers, Rogers’s placidity belied the intense care he took in shaping each episode of his program. He insisted that every word, whether spoken by a person or a puppet, be scrutinized closely, because he knew that children—the preschool-age boys and girls who made up the core of his audience—tend to hear things literally.
Preventative soon drew enough attention that The New York Mirror devoted a whole column to it in the newspaper's March 6, 1824, edition. "The conversion of preventive into preventative is an error too common," wrote the anonymous scribe. "Some fall into it from ignorance, and others from inadvertence." The writer attributed its use to "a disposition in people to spell words with more letters than belong to them; or to insert a syllable or syllables, where addition, so far from being advisable or requisite, proves injurious." The column concluded with a call to action: "Let those, then, who from carelessness or any other cause, have been in the habit of using preventative, make it henceforth an invariable rule, whether in writing or in utterance, to prefer the proper and unexceptionable term preventive."
A positive result, in the absence of unequivocal high blood sugar, should be confirmed by a repeat of any of the above methods on a different day. It is preferable to measure a fasting glucose level because of the ease of measurement and the considerable time commitment of formal glucose tolerance testing, which takes two hours to complete and offers no prognostic advantage over the fasting test. According to the current definition, two fasting glucose measurements above 7.0 mmol/l (126 mg/dl) is considered diagnostic for diabetes mellitus.
The guidelines, if widely accepted, would affect up to a quarter of Americans living with diabetes whose BMI is between 30 and 35. Worldwide, the effects would be even greater, since the majority of the 422 million people with diabetes have a BMI lower than 35. For people of Asian descent, the DSS-II agreed surgery could be considered for people down to 27.5 BMI, since many patients of Asian decent develop diabetes at a lower BMI.
Abnormal cholesterol and triglyceride levels. If you have low levels of high-density lipoprotein (HDL), or "good," cholesterol, your risk of type 2 diabetes is higher. Triglycerides are another type of fat carried in the blood. People with high levels of triglycerides have an increased risk of type 2 diabetes. Your doctor can let you know what your cholesterol and triglyceride levels are.
