text_1: I have a 65-year-old woman with Type 2 diabetes who was new to me 7 months ago.  The Food and Drug Administration recently said not to use glitazones with insulin because of the risk of congestive heart failure.  But now her glycosylated hemoglobin is better and her insulin requirement is down to 40 in the morning and 32 at night.  So what do you do with that information?
text_2: Is it acceptable to continue high-dose pioglitazone along with insulin?
