An external link to the publisher’s copy is included.As suboptimal blood glucose control has a lasting harmful effect even if control improves later, intensive insulin therapy to minimise hyperglycaemia is now recommended for all patients with type 1 diabetes. The new rapid- and long-acting insulin analogues offer more physiological insulin profiles than traditional insulin preparations. Continuous insulin infusion (“pump therapy”) may provide a solution for some patients with frequent hypoglycaemia or hypoglycaemic unawareness. Continuous blood glucose monitoring reveals postprandial hyperglycaemia and asymptomatic nocturnal hypoglycaemia and may be especially useful for programming overnight basal insulin rates for pump therapy. In type 2 diabetes, management should change with disease progression; introduction of insulin should not be delayed if metabolic control becomes suboptimal. More individualised and physiological therapy is now possible.Jennifer J Couper and Johannes B Prin

Novel mechanisms of endothelial dysfunction in diabetes

Diabetes mellitus is a major risk factor for cardiovascular morbidity and mortality. This condition increases the risk of developing coronary, cerebrovascular, and peripheral arterial disease fourfold. Endothelial dysfunction is a major contributor to the pathogenesis of vascular disease in diabetes mellitus patients and has recently received increased attention. In this review article, some recent developments that could improve the knowledge of diabetes-induced endothelial dysfunction are discussed

Identification of self-management patterns in pediatric type 1 diabetes using cluster analysis

This study identified three distinct patterns of self-management groups for a sample of 239 youth (9-11 years) with type 1 diabetes and their maternal and paternal caregivers, and assessed their relationship to glycemic control (HbA1c). Youth and their maternal and paternal caregivers were administered the diabetes self-management profile (DSMP) to assess self-management. Glycemic control was based on hemoglobin A1c. Two-step cluster analysis identified three different self-management groups based on youth, maternal, and paternal reports. Analysis of variance indicated that the pattern of less optimal diabetes self-management was associated with worse glycemic control. Our results objectively describe differences in patterns of self-management in youth with type 1 diabetes, that relate to glycemic control. Interventions based on these specific patterns of self-management may improve diabetes management and enhance glycemic control in children and adolescents with type 1 diabetes
