BACKGROUND High-resolution MRI has been shown to be capable of identifying plaque constituents, such as the necrotic core and intraplaque hemorrhage, in human carotid atherosclerosis. The purpose of this study was to evaluate differential contrast-weighted images, specifically a multispectral MR technique, to improve the accuracy of identifying the(More)
Sixty patients undergoing colorectal surgery for malignancy were randomized to receive the anabolic steroid stanozolol (n = 30) or to a control group (n = 30). Patients were further randomized to receive on the first 4 postoperative days a) a standard dextrose-saline regimen (DS), b) an amino acid regimen (AA), or c) a glucose-amino acid-fat regimen (GAF)(More)
The relationship between cancer, weight loss, and resting energy expenditure (REE) has been investigated in 136 patients using indirect calorimetry. Ninety-one patients had gastric, colorectal, or nonsmall cell bronchial neoplasm, seven patients had other malignancies, and 38 patients had nonmalignant illness. Four groups were studied: weight stable cancer(More)
In an attempt to define the mechanism of weight loss in cancer patients, fat and carbohydrate oxidation rates were calculated in 93 patients. Seventy patients with colorectal or gastric cancer were compared with a control group of 23 patients with nonmalignant illness. Twenty-seven patients with cancer and 13 control patients had lost more than 10% of their(More)
Whole body protein turnover and resting energy expenditure are measured simultaneously in weight stable and weight losing patients with lung (n = 22) or colorectal cancer (n = 38). These results were compared with those from weight stable and weight losing non-cancer controls (n = 22). Rates of whole body protein turnover were calculated from the plateau(More)
The presence of a malignant tumor is said to influence the resting energy expenditure (REE) of the host. This study assesses the hypothesis that different tumor types exert differing effects on REE. REE was measured using indirect calorimetry in 84 cancer patients. Fifty-one patients had colorectal cancer, 22 had gastric cancer, and 11 had non-small cell(More)
