Incretins such as glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) are intestinal postprandial hormones that stimulate insulin release from the pancreas as long as circulating glucose concentrations are raised. In addition to their effect on insulin secretion and consequent glucose lowering, GIP and GLP-1, especially the latter, have a number of physiological effects such as inhibition of glucagon release, gastric emptying and food intake, as well as a tropic action on pancreatic B-cell mass. There is currently a pandemic of obesity and diabetes, and existing treatments are largely inadequate both in regard to efficacy as well as their ability to tackle important factors in the pathogenesis of type 2 diabetes (T2D). ⋯ Consequently, achieving better control of diabetes with lower HbA1c is the goal of optimal treatment. Despite the use of usual therapeutic agents in T2D, often in high doses and as combinations, such as metformin, sulphonylurea, alpha-glycosidase inhibitors, thiazolidinediones and a number of animal and human insulin preparations, optimal control of glycaemia is not achieved. The use of incretins as therapeutic agents offers a new approach to the treatment of T2D.

To test the hypothesis that compliance with a hospital protocol on peripheral blood culture (PBC) collection in adults is associated with a reduction in PBC contamination, and to investigate likely contributing factors for contamination. ⋯ Compliance with a hospital protocol on PBC collection technique in adults significantly reduces blood culture contamination.

Various scales have been devised to predict development of pressure ulcers on the basis of clinical and laboratory data, such as the Braden Scale (Braden score), which is used to monitor activity and skin conditions of bedridden patients. However, none of these scales facilitates clinically reliable prediction. ⋯ The new indicator may become a more useful clinical tool for predicting presser ulcers than Braden score. The new indicator warrants verification studies to facilitate its clinical implementation in the future.

To analyse the contributions of the 15 primary member states of the European Union and selected non-European countries to pathological research between 2000 and 2006. ⋯ Results mirror the leading role of the USA in pathology research but also show the relevance of European scientists. The scientometric approach in this study provides a new fundamental and comparative overview of pathology research in the European Union and the USA which could help to benchmark scientific output among countries.
