The aim of this study was to evaluate the value of statins in reducing abdominal aortic aneurysm (AAA) growth rate and improving freedom from aneurysm repair or rupture. One hundred and twenty-one patients with AAA undergoing ultrasonographic surveillance for at least one year were included in this retrospective study. Patients treated with statins had a decreased linear aneurysm growth rate than those not receiving statins (1.9+/-1.8 mm/year vs. 2.6+/-2.4 mm/year, P=0.27), but this difference did not reach statistical significance. Statin users had a better survival freedom from aneurysm repair or rupture (at 5 years: 72.3% vs. 52.5%, P=0.048). The impact of treatment with statins was even more evident in patients with a baseline aneurysm diameter<40 mm (at 5 years: 84.0% vs. 58.8%, P=0.022). When adjusted for age, coronary artery disease and baseline aneurysm diameter, treatment with statins had significantly better survival freedom from aneurysm repair or rupture (P=0.012, RR 0.34, 95% CI 0.14-0.78). The use of statins seems to slightly decrease the AAA growth rate and to significantly improve freedom from aneurysm repair and rupture.

The neuroprotective efficacy of off-pump coronary artery bypass surgery is marginal compared with that of conventional coronary artery bypass surgery. A decreased risk of postoperative stroke after off-pump coronary artery bypass surgery is expected, mostly in high-risk patients and when epiaortic ultrasonographic examination is routinely used for better planning of operative strategy, aiming to minimize the risk of intraoperative embolism.

In producing persistently high cell homing at the infarction site, the IM transplantation is superior to the IC transplantation. However, the IC administration might be more specific in targeting injured capillaries and epithelial cells within the infarcted myocardium.

The results show that acute edematous pancreatitis is characterized by induction of apoptosis, whereas full-blown pancreatitis is characterized by necrosis. Impaired vascular permeability to albumin and protein is related to the early phase of necrotic pancreatitis. Claudin-2 increases during acute necrotic and edematous pancreatitis and may be related to impaired permeability.

Autologous bone marrow-derived mononuclear cells at the infarcted area localize in the myocardium. The exact mechanism of recovery remains to be determined, but our findings may give new information concerning the cellular events that occur during cell therapy-enhanced recovery.

The leukocyte-depleting filter succeeded in reducing the number of adherent leukocytes during the reperfusion period in an experimental operation with deep hypothermic circulatory arrest. Such a filter thus could mitigate cerebral reperfusion injury after cardiac surgery.
