Abstract:
The IMPROVE™ study is the largest observational study of therapy in Type 2 diabetes mellitus to date. It is a multinational study investigating the safety and efficacy of biphasic insulin aspart 30/70 (BIAsp 30) in the routine management of patients with Type 2 diabetes mellitus. Five published reports on this study have provided baseline demographic information for patients receiving BIAsp 30 in eight countries, information on the safety and efficacy outcomes for those patients and analyses of three subgroups of patients who were insulin-naive, receiving basal insulin or receiving biphasic human insulin before the start of the study. These subanalyses provided information on the optimal prescribing and dosing strategies when starting treatment with BIAsp 30 in these groups of patients in normal clinical practice. The study extends the results from clinical trials of BIAsp 30 and confirms its benefits in routine care, in a large, global, heterogeneous patient population.

Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
