From a cardiovascular perspective, rosiglitazone, saxagliptin, and alogliptin appear to be relatively safe. It is disappointing, however, that neither intensive glycemic control nor the use of specific diabetes medications is associated with any suggestion of cardiovascular benefit. Thus the evidence does not support the use of glycated hemoglobin as a valid surrogate for assessing either the cardiovascular risks or the cardiovascular benefits of diabetes therapy. Patients with type 2 diabetes and their physicians currently have numerous treatment options, and additional drugs are in development. Perhaps the recent experience with rosiglitazone will allow the FDA to become more targeted in its adjudication of the cardiovascular safety of new diabetes drugs, focusing the considerable resources needed to rule out a cardiovascular concern only on drugs with clinical or preclinical justification for that expenditure. New therapies targeting glycemic control may have cardiovascular benefit, but this has yet to be shown. The optimal approach to the reduction of cardiovascular risk in diabetes should focus on aggressive management of the standard cardiovascular risk factors rather than on intensive glycemic control.

Truog, M.D., Franklin G. Miller, Ph.D., and Scott D. Halpern, M.D., Ph.D. The ethics of organ transplantation have been premised on “the dead-donor rule” (DDR), which states that vital organs should be taken only from persons who are dead. Yet it is not obvious why certain living patients, such as those who are near death but on life support, should not be allowed to donate their organs, if doing so would benefit others and be consistent with their own interests. This issue is not merely theoretical. In one recent case, the parents of a young girl wanted to donate her organs after an accident had left her with devastating brain damage. Plans were made to withdraw life support and to procure her organs shortly after death. But the attempt to donate was aborted because the girl did not die quickly enough to allow procurement of viable organs. Her parents experienced this failure to donate as a second loss; they questioned why their daughter could not have been given an anesthetic and had the organs removed before life support was stopped. As another parent of a donor child observed when confronted by the limitations of the DDR, “There was no chance at all that our daughter was going to survive. . . . I can follow the ethicist’s argument, but it seems totally ludicrous.”1 In another recent case described by Dr. Joseph Darby at the University of Pittsburgh Medical Center, the family of a man with devastating brain injury requested withdrawal of life support. The man had been a strong advocate of organ donation, but he was not a candidate for any of the traditional approaches. His family therefore sought permission for him to donate organs before death. To comply with the DDR, plans were made to remove only nonvital organs (a kidney and a lobe of the liver) while he was under anesthesia and then take him back to the intensive care unit, where life support would be withdrawn. Although the plan was endorsed by the
