[Evaluation of resistance to activated protein C in myocardial infarction patients].

It is known that resistance to activated protein C (APCR), often associated with a single point mutation (Arg506--Gln) in the coagulation factor V gene (factor V Leiden), is the most frequent inherited abnormality of blood coagulation. It plays a key role as pathogenetic factor of venous thromboembolism, but its association with an increased risk of arterial thrombosis is uncertain. Aim of the present study was to evaluate the prevalence of APCR in men, who suffered myocardial infarction more than 6 months earlier and without cardiovascular risk factors (hypercholesterolemia, smoking, diabetes, obesity and hypertension).The study was carried on 20 men aged65 years who have suffered myocardi…

Albumin replacement in patients with severe sepsis or septic shock.

BACKGROUND: Although previous studies have suggested the potential advantages of albumin administration in patients with severe sepsis, its efficacy has not been fully established. METHODS: In this multicenter, open-label trial, we randomly assigned 1818 patients with severe sepsis, in 100 intensive care units (ICUs), to receive either 20% albumin and crystalloid solution or crystalloid solution alone. In the albumin group, the target serum albumin concentration was 30 g per liter or more until discharge from the ICU or 28 days after randomization. The primary outcome was death from any cause at 28 days. Secondary outcomes were death from any cause at 90 days, the number of patients with or…
