Articles

  • Exercise reduces blood pressure in both hypertensive and normotensive persons. An increase in aerobic physical activity should be considered an important component of lifestyle modification for prevention and treatment of high blood pressure.

  • When the goal of insulin therapy in type 1 diabetes mellitus is near-normoglycemia, splitting the evening insulin treatment regimen into short-acting insulin at dinner and neutral protamine Hagedorn (NPH) insulin at bedtime reduces the risks for nocturnal hypoglycemia and hypoglycemia unawareness and decreases the hemoglobin A1c value compared with mixing short-acting insulin and NPH insulin at dinner.

  • Although limited by the small sample and lack of long-term observations, this study shows that oral sildenafil is a potent pulmonary vasodilator that acts synergistically with inhaled iloprost to cause pulmonary vasodilatation in both severe pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension.

Brief Communications

  • In this study, coronary flow reserve decreased after a single high-fat meal in young healthy men. High-fat meals may be detrimental to coronary microcirculation.

  • C-reactive protein (CRP) predicts risk for future cardiovascular events in asymptomatic persons. However, because CRP also predicts total mortality, its specificity for vascular disease is uncertain. This study found that CRP level appears to independently predict cardiovascular events but not cancer.

Updates

  • This Update discusses many aspects of aplastic anemia, including its immune pathophysiology, its place as a hematologic disease and as an immune-mediated syndrome, the differential diagnosis of bone marrow failure, the possibility of an infectious cause, available treatments, and evolution to other hematologic diseases and late clonal events.

Editorials

  • In this issue, Fanelli and colleagues compared split-dose and mixed-dose insulin regimens in patients with type 1 diabetes mellitus. Evidence now suggests that for a selected group of persons with type 1 diabetes mellitus, an extra shot at bedtime should be considered, although newer insulin analogues may yield additional approaches and benefits in the near future.

  • Consistent results from more than 15 well-conducted prospective studies in initially healthy persons have shown a strong and independent association between the circulating C-reactive protein level and cardiovascular end points. As Rifai and colleagues show in this issue, the empirical measurement of C-reactive protein is a powerful predictor of cardiovascular risk regardless of the underlying mechanisms.

  • PIER (Physicians' Information and Education Resource), a new information product for the clinician, will be available beginning April 11 to American College of Physicians–American Society of Internal Medicine members (http://πer.acponline.org/). PIER represents a new direction in medical publishing because it will help clinicians address complex, multifaceted questions in an informed manner.

Medical Writings

  • Consider an addition to the medical record—one that heretofore was implicitly present but now must be made explicit: Insert a section called Ethical Concerns.
