Several methods, each with differing utility and limitations, exist for monitoring glycemic control. Hemoglobin A1c (HbA1c) is considered the standard measure of long-term glycemic control, and HbA1c levels are strongly associated with complications of diabetes. However, HbA1c does not provide "real-time" information about individual hyperglycemic or hypoglycemic excursions. ⋯ It is an educational tool for both patients and their healthcare providers to understand the effects of diet, exercise, and medications on day-to-day glycemic control. However, guidelines from various international diabetes organizations vary in their level of specificity regarding the frequency and timing of self-monitoring. SMBG should be implemented for all patients as part of an overall diabetes management plan that includes specific instruction on how, when, and why to test.

Despite the increasing prevalence of diabetes, improved understanding of the disease, and a variety of new medications, glycemic control does not appear to be improving. Self-monitoring of blood glucose (SMBG) is one strategy for improving glycemic control; however, patient adherence is suboptimal and proper education and follow-up are crucial. ⋯ Situations in which SMBG is essential or should be more frequent include self-adjustment of insulin doses, changes in medications, lack of awareness of hypoglycemia, gestational diabetes, illness, or when hemoglobin A1c (HbA1c) values are above target. SMBG should include postprandial monitoring to identify glycemic excursions after meals, to indicate the need for lifestyle adjustments, and to provide patient feedback on dietary choices.

Comparative Study
Outcomes in African Americans and whites after percutaneous coronary intervention.
We aimed to determine whether African Americans and whites have different outcomes after percutaneous coronary intervention (PCI). ⋯ After PCI, African Americans have similar short-term rates of death or myocardial infarction when compared with whites but have a nonsignificant trend toward worse long-term outcomes. Our findings, when interpreted in the context of reportedly lower revascularization rates among African Americans, suggest that continued efforts to optimize the appropriate use of coronary revascularization among African Americans are warranted.

Because there is little information about the training that general internists require to perform hand-carried cardiac ultrasonography (HCU), we studied the rate of learning of a group of medical residents performing HCU after minimal formal training. ⋯ This study, the first prospective, experimental effort of its kind, shows that residents as a group learned important aspects of HCU scanning and interpretation at a reasonably rapid rate.
