Later this month you will be meeting with Dr. Schubart for the Diabetes Master Class.\u00a0\u00a0 The goals of the sessions are to solidify our knowledge of the basics of diabetes treatment and to challenge us to become more expert in the treatment of this common condition.<\/p>\n

To attain these goals, we will read the latest recommendations of the ADA in detail, improving our familiarity with the large clinical trials that constitute the basis of the recommendations. \u00a0The 2014 guidelines promulgated by the ADA are careful to distinguish recommendations based on the results of large RCTs from those based on expert opinion, to differentiate between what is known and what is not yet known. \u00a0The older, trialed and true treatments have brought improvements in important outcomes, however \u00a0reductions in mortality and macrovascular complications have proven difficult to come by; older agents also appear not to reverse or retard the underlying pathophysiology – insulin resistance and progressive beta cell loss. \u00a0In recognition of these difficulties, the guidelines “allow” use of newer agents for which the evidence base is necessarily incomplete.<\/p>\n

Everyone should complete the test below prior to the class.\u00a0 You are encouraged, indeed required, to do the test in an \u201copen book\u201d fashion.\u00a0 Read the guidelines summary and recommendations in detail. \u00a0Also read the attached article by DeFronzo et al in which they describe a different approach, based more on what is known about the pathophysiology of diabetes than the results of large clinical trials. \u00a0 Google and PubMed.\u00a0 Work together.\u00a0 Ask anyone you like.\u00a0 Please turn in a copy of your answers at the beginning of the class.<\/p>\n

In addition to completing the test, each of you will be assigned one of the questions.\u00a0 You will lead a discussion of the question.\u00a0 You may prepare a powerpoint or a handout if you\u2019d like.<\/p>\n

Many of the questions below, though in multiple choice format, are not standard multiple choice.\u00a0 There are often multiple correct choices.\u00a0 For cxample the queston may ask \u201cWhich of the following is true?\u201d\u00a0 and B and C may both be true while A,D, and E are not.\u00a0 Try to get them all right.<\/p>\n

Here is the ADA “Standards of Medical Care in Diabetes – 2014”:\u00a0Dia Care-2014–S14-80

G. Nateglinide<\/td>\n7. Decreases\u00a0 insulin resistance by causing conformational change in insulin receptors in muscle<\/td>\n<\/tr>\n
