Randomized Controlled TrialSimvastatin and rosuvastatin mobilize Endothelial Progenitor Cells but do not prevent their acute decrease during systemic inflammation.
Endothelial Progenitor Cells (EPCs) are a specific subtype of haematopoietic stem cells that contribute to the repair of injured endothelium. Treatment with atorvastatin has been shown to increase EPC counts in patients with stable coronary artery disease. Numbers of circulating EPCs decrease in various inflammatory diseases. Thus, we hypothesized that short term statin pre-treatment may alter the acute change in EPC levels during systemic inflammation. ⋯ Statin therapy significantly increases EPCs within 96 hours and this may be a class effect. However, statins could not counteract the acute decrease in circulating EPCs after LPS infusion.

Randomized Controlled TrialThe relationship between maintenance dosages of three vitamin K antagonists: acenocoumarol, warfarin and phenprocoumon.
Vitamin K antagonists of the coumarin type are widely used oral anticoagulants. ⋯ We determined the transition factors between warfarin, phenprocoumon and acenocoumarol. With these transition factors physicians are able to estimate the maintenance dose when it is necessary for a patient to switch from one coumarin to the other.

Randomized Controlled TrialImproved fibrinolytic activity during exercise may be an effect of the adipocyte-derived hormones leptin and adiponectin.
Physical activity is associated with improved fibrinolytic activity and reduced risk for cardiovascular disease. High levels of leptin and low levels of adiponectin, both adipocyte-derived hormones, or adipokines, are related to dysfibrinolysis and risk for cardiovascular disease. In this study, we explored if improved fibrinolytic activity during exercise could be linked to changes in leptin and adiponectin levels. ⋯ Heavy exercise induced improved fibrinolytic activity, which was associated independently with changes in circulating levels of the adipocyte-derived hormones leptin and adiponectin. Improved fibrinolytic activity (and reduced risk for cardiovascular disease) related to physical activity could possibly be mediated by leptin and adiponectin.
