The overall complexity of the surgery was perceived lower in the LCD group (p < 0.05), due to improved exposure and reduced psychological stress (both p < 0.05). Four weeks of preoperative LCD resulted in a significant decrease in liver volume and intrahepatic fat content, and facilitated the subsequent laparoscopic gastric bypass as scored by the surgeon.

Background In several reports, C3 and C4 have been linked to diabetes and cardiovascular disease (CVD). Here, we investigate this link and the degree of C3 activation in elderly individuals.

The effects on glucose metabolism by the beta-blocker atenolol and the angiotensin-converting enzyme (ACE)-inhibitor trandolapril were investigated in a randomised double-blind parallel group study of patients with primary hypertension. Twenty-six patients were treated with 50-100 mg atenolol and 27 patients with 2-4 mg trandolapril o.d. Intravenous glucose tolerance tests, euglycaemic hyperinsulinaemic clamps and serum lipid measurements were performed after 8 and 48 weeks of active treatment. After 48 weeks insulin sensitivity was reduced by 23% by atenolol while it remained unchanged during trandolapril treatment (؉0.5%, P ‫؍‬ 0.0010 for difference between treatments, ANCOVA). The effect on triglycerides (؉22% vs ؊8.5%)
