“…Indirectly, the small intestine takes part in the regulation of the cholesterol pool size througli the ileal reabsorption of bile acids (13). Interference with the intestinal regulation with resulting changes of the plasma lipid com position can be induced by intestinal surgery (5) and has found clinical application in the bypass operation for treatment of familial hypercholesterolaemia (3,24) and extreme obesity (15,28). Lipoprotein data from such patients are, however, not directly applicable to patients with Crohn's disease in whom the preoperative condition is characterized by ac tive inflammatory disease and malnutrition and the surgical procedure usually includes resec tion of the most distal part of the small in testine.…”

Serum lipoproteins and fecal fat were determined in 37 patients with Crohn’s disease, who had been submitted to ileal resections. All patients were studied in a quiescent phase of the disease, on average 5 years after the last operation, and all except one had a daily intake of dietary fat lower than 70 g. A significant positive correlation existed between the length of the resected intestine and the fecal fat excretion. Total triglyceride (TG) concentrations were similar in patients and a group of carefully matched controls. In spite of a mean resection length of 8.6 dm of ileum, hypertriglyceridaemia (type IV) was found in 7 patients. The reduced cholesterol concentration in the patients was due to a marked reduction of the low-density lipoprotein (LDL) cholesterol concentration. The LDL cholesterol concentration was negatively correlated to the length of the resected intestine. The average high-density lipoprotein (HDL) concentration was similar in healthy controls and patients, but in the latter the HDL cholesterol concentrations were lower the more extensive the ileal resections. The very-low-density lipoprotein cholesterol concentration showed no significant abnormality. These data support the concept that in patients with ileal resections other factors may compensate for the limited dietary fat supply to maintain a normal TG concentration in plasma. The low total cholesterol concentration is due to a reduction in the LDL fraction only, and reflects probably that all cholesterol used for enhanced bile acid synthesis is provided by this fraction. The negative correlation between the extent of the resection and the HDL cholesterol concentration supports indirectly the hypothesis that HDL particles may be secreted not only from the liver but also from the small intestine.

“…Garner et al (1981) note that despite the advantages of more empirical measurement techniques, the literature on body image has been hampered by numerous methodological shortcomings. They note a technological development by Allebeck, Hallberg and Espmark (1976) in which body size perception is measured through adjusting one's own body image on a T V monitor. This methodology has been used only infrequently in recent years to measure body image in obese subjects (Collins, McCabe, & Jupp, 1983; and has not been used with anorexic subjects.…”

Body image in anorexic and normal weight female subjects was investigated with a video TV monitor. Eighteen subjects were presented with a task in which they manipulated their body size to obtain “ideal” and actual images and a task wherein they judged the accuracy of a projected image of their body. There were no differences in estimated actual body size between anorexics and control subjects. For both groups, ideal images were below their actual image. For the second task, a signal detection analysis revealed no sensory sensivitity differences between weight groups. Anorexic subjects were more likely to report and image of themselves as distorted, regardless of whether distortion was present. Both weight groups adopted a strict criterion when they were viewing a heavy image of themselves. The finding that body estimation difference between anorexics and controls is non‐sensory are discussed, and ramifications for treatment of anorexia are described.

Exercise energy expenditure in extreme obesity: influence of ergometry type and weight loss

Bicycle and treadmill exercise tests including oxygen uptake (VO2) and heart rate (HR) determination were carried out on a total of thirty patients with obesity, seventeen of whom were reinvestigated after weight loss. During both types of work VO2 for a given load was higher when compared to healthy controls. The increase of VO2 was more marked when cycling was performed in sitting position than in supine. The mechanical efficiency of sitting bicycle exercise averaged 17.8% and was negatively related to the percentage overweight; the slope of the VO2/load regression line was slightly less in comparison to the controls, while no such difference was found during treadmill walking. After weight reduction the VO2/load regression line was skifted downwards, the slopes being unchanged, thus the mechanical efficiency improved. This study not only confirms the observation of a low mechanical efficiency of obese subjects but also demonstrates that the change is quantitatively related to the overweight. The lowered efficiency was caused by body mechanical factors and there was no support for an abnormal muscular efficiency. Exercise tests should be combined with VO2 determination, if used to assess the circulatory capacity of obese subjects.
