It is recognized that reducing hyperglycemia early on in disease progression has long-term benefits for patients with diabetes. Insulin therapy has greater potential to reduce hyperglycemia than other therapies; however, there is often a significant delay in insulin initiation and intensification. ⋯ Large clinical trials have improved our understanding of the potential benefits and risks associated with intensive glycemic control in different patient populations and highlighted the need for individualization of glycemic targets and treatment strategies. Current treatment guidelines recognize the important role of insulin therapy both early on and throughout the progression of type 2 diabetes.

Hypoglycemia is a common, potentially avoidable consequence of diabetes treatment and is a major barrier to initiating or intensifying antihyperglycemic therapy in efforts to achieve better glycemic control. Therapy regimen and a history of hypoglycemia are the most important predictors of future events. Other risk factors include renal insufficiency, older age, and history of hypoglycemia-associated autonomic failure. ⋯ Economically, hypoglycemia burdens the healthcare system and adversely affects workplace productivity, particularly after a nocturnal event. Ongoing healthcare reform efforts will result in even more emphasis on reducing this side effect of diabetes treatment. Therefore, improving patients' self-management skills and selecting or modifying therapy to reduce the risk of hypoglycemia will increase in importance for clinicians and patients alike.

The development of insulin analogs has made improved treatment of type 2 diabetes possible. In this article, structural alterations, pharmacokinetics and pharmacodynamics, clinical end points, and safety issues are reviewed for the currently available basal insulins, rapid-acting insulins, and premixes. The flatter activity profiles of insulin glargine and insulin detemir translate into good clinical efficacy with a lower risk of hypoglycemia relative to neutral protamine Hagedorn insulin. ⋯ Convenience is greater for patients because the analogs can be injected just before a meal. In premix or biphasic insulins, a proportion of the rapid-acting analog is protaminated, providing both rapid-acting and intermediate-acting components in one formulation, thus reducing the number of injections required. Alterations to human insulin have resulted in improvements in safety, efficacy, tolerability, and convenience for patients.

The choice to recommend antithrombotic therapy to patients with atrial fibrillation should rely on cardioembolic and bleeding risk stratification. Sharing some risk factors, schemes to predict thrombotic and bleeding risk are expected not to be independent, yet the degree of their association has never been clearly quantified. ⋯ In a real-world population with atrial fibrillation, we confirmed that the cardioembolic and bleeding risk classifications are correlated but not exchangeable. It is then worth verifying the advantages of a strategy adopting a combined risk assessment over a strategy relying only on the cardioembolic risk evaluation.
