Are circulating endothelial cells associated with future vascular events in hemodialysis patients?
In this hemodialysis population, an increase in circulating endothelial cells was found to predict the development of cardiovascular and vascular events, and to be independent of other known markers of inflammation or endothelial dysfunction. These studies suggest that circulating endothelial cells may be a novel way to assess endothelial health and cardiovascular risk. Further studies to investigate the utility of circulating endothelial cells in predicting cardiovascular risk are needed.
Accurate clinical assessment of lateral neck infections is poor, generally under estimating suppuration. However, when an abscess is diagnosed clinically this correlates highly with the surgical finding. Radiological assessment has inaccuracy in identifying suppuration and this should be borne in mind when being used as a diagnostic tool for neck infections.
