The association between metabolic syndrome and restrictive ventilatory dysfunction in older persons.

Background: The restrictive, but not the obstructive respiratory dysfunction, is associated with an increased risk of developing type 2 diabetes mellitus. Our aim was to verify in an elderly nondiabetic population whether a restrictive respiratory pattern was associated with a higher prevalence of metabolic syndrome and increased insulin resistance than were obstructive and normal respiratory patterns.

Methods: We performed a cross-sectional study of 159 consecutive nondiabetic elderly persons attending two social centers.

Simvastatin reduces CD40 expression in an experimental model of early arterialization of saphenous vein graft.

Background: Saphenous vein graft (VG) failure occurs more frequently compared with arterial grafts, and graft thrombosis represents the main cause of early occlusion. Because CD40-CD40L pathway CD40 represents a culprit link between local inflammation and coagulation cascade, we investigate the role of CD40 and its soluble ligand (sCD40L) in the immediate in vitro response of VG to arterial pressures, and the potential effects of Simvastatin (Merck Sharp&Dohme, White-house Station, NJ) supplementation.

Methods: Samples of saphenous vein and of internal mammary artery (IMA) were obtained from sixteen patients without history of statin therapy.

Multiple osteochondroses of bilateral knee joints: a case report.

Knee injuries in young athletes include not only the typical adult bone injuries, ligament and cartilage, but also the growth plate lesions. Osteochondroses are idiopathic, self-limited disturbance of enchondral ossification in which a rapid growth spurt is present. The patella could be affected by two different kinds of osteochondroses: Kohler syndrome and Sinding-Larsen-Johansson.

Simvastatin blunts the increase of circulating adhesion molecules after coronary artery bypass surgery with cardiopulmonary bypass.

Objectives: Endothelial dysfunction has been shown to be a critical early component of organ injury after myocardial ischemia and reperfusion. Circulating levels of adhesion molecules have been regarded as a valid index of endothelial activation. Recent reports suggest that statins, widely used in the control of hypercholesterolemia, exert a protective effect on the endothelium reflected by a reduced level of circulating adhesion molecules.
