Effects of losartan on renal and cardiovascular outcomes in patients with type 2 diabetes and nephropathy

Abstract: Background Diabetic nephropathy is the leading cause of end-stage renal disease. Interruption of the renin–angiotensin system slows the progression of renal disease in patients with type 1 diabetes, but similar data are not available for patients with type 2, the most common form of diabetes. We assessed the role of the angiotensin-II–receptor antagonist losartan in patients with type 2 diabetes and nephropathy. Methods A total of 1513 patients were enrolled in this randomized, double-blind study comparing losartan (50 to 100 mg once daily) with placebo, both taken in addition to conventional antihypertensive treatment (calcium-channel antagonists, diuretics, alpha-blockers, beta-blockers, and centrally acting agents), for a mean of 3.4 years. The primary outcome was the composite of a doubling of the base-line serum creatinine concentration, end-stage renal disease, or death. Secondary end points included a composite of morbidity and mortality from cardiovascular causes, proteinuria, and the rate of prog...

The Yale-Brown Obsessive-Compulsive Scale: Measures of internal consistency

Abstract: We examined the construction of the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) and performance of subscale items based on data from 204 patients with obsessive-compulsive disorder (OCD) who participated in a multicenter drug treatment study. Factor analysis was used to examine the relationship among the 10 items that make up the Y-BOCS instrument. Models were computed in which both two- and three-factor solutions were estimated. Within the two-factor solution analyses, the factor distribution was not so consistent as in the three-factor solution analyses, and a shift in the factor distribution was noted after treatment. In the three-factor solution analyses, an independent resistance construct emerged in addition to the obsessive and compulsive constructs. Examination of the postreatment factor scores showed that the Y-BOCS resistance items did not assess OCD symptom change as sensitively as the rest of the Y-BOCS items did.

Complications of Endoscopic Biliary Sphincterotomy

Abstract: Background Endoscopic sphincterotomy is commonly used to remove bile-duct stones and to treat other problems. We prospectively investigated risk factors for complications of this procedure and their outcomes. Methods We studied complications that occurred within 30 days of endoscopic biliary sphincterotomy in consecutive patients treated at 17 institutions in the United States and Canada from 1992 through 1994. Results Of 2347 patients, 229 (9.8 percent) had a complication, including pancreatitis in 127 (5.4 percent) and hemorrhage in 48 (2.0 percent). There were 55 deaths from all causes within 30 days; death was directly or indirectly related to the procedure in 10 cases. Of five significant risk factors for complications identified in a multivariate analysis, two were characteristics of the patients (suspected dysfunction of the sphincter of Oddi as an indication for the procedure and the presence of cirrhosis) and three were related to the endoscopic technique (difficulty in cannulating the bile duct,...
