BACKGROUND/AIMS The causes of ulcerative colitis are unknown, although it is plausible that dietary factors are involved. Case-control studies of diet and ulcerative colitis are subject to recall biases. The aim of this study was to examine the prospective relationship between the intake of nutrients and the development of ulcerative colitis in a cohort(More)
OBJECTIVE Dietary linoleic acid, an n-6 polyunsaturated fatty acid, is metabolised to arachidonic acid, a component of colonocyte membranes. Metabolites of arachidonic acid have pro-inflammatory properties and are increased in the mucosa of patients with ulcerative colitis. The aim of this investigation was to conduct the first prospective cohort study(More)
OBJECTIVES:Obesity is associated with a proinflammatory state that may be involved in the etiology of inflammatory bowel disease (IBD), for which there are plausible biological mechanisms. Our aim was to perform the first prospective cohort study investigating if there is an association between obesity and the development of incident IBD.METHODS:A total of(More)
Pancreatic cancer kills more than 250,000 people each year worldwide and has a poor prognosis. The aim of this article is to critically review the epidemiologic evidence for exposures that may either increase or decrease the risk. A Medline search was performed for epidemiologic studies and reviews published up to April 2007. Consistent evidence of a(More)
Eleven fasted adult men consumed a chicken meat sandwich made with white or wholemeal bread, extrinsically labelled with 2 mg 67Zn, on two different occasions. Immediately after eating the sandwich they were given an intravenous injection of 1.5 mg 70Zn. True Zn absorption (which was approximately 7% higher than apparent absorption) was determined by the(More)
Ulcerative colitis (UC) is chronic inflammation of large intestine and often requires lifelong medication. Medical therapy aims to induce and maintain a clinical remission, reduce the risk of colorectal cancer and improve quality of life. Aminosalicylates are currently the first choice therapy both for the induction and the maintenance of remission in the(More)
Estimates of the spanchnic retention and appearance in the systemic circulation of orally administered glucose vary among laboratories even after recently identified sources of error have been accounted for [Livesey, G., P. D. G. Wilson, J. R. Dainty, J. C. Brown, R. M. Faulks, M. A. Roe, T. A. Newman, J. Eagles, F. A. Mellon, and R. Greenwood. Am. J.(More)
The fasting and postprandial levels of insulin, gastric inhibitory polypeptide, gastrin, motilin, human pancreatic polypeptide, enteroglucagon and neurotensin have been measured in 10 subjects with a permanent ileostomy and in 10 healthy control subjects matched for age and sex. Most of the levels were similar in the two groups but the group that had(More)
BACKGROUND Aspirin has detrimental effects on the gastrointestinal tract mucosa and may play a role in the aetiology of inflammatory bowel disease. AIM To investigate if the regular use of aspirin is associated with the development of Crohn's disease (CD) and ulcerative colitis (UC) using, for the first time, a prospective cohort study design. METHODS A(More)
It has been suggested that incomplete digestion of cereal starch explains the low energy values of certain cereals of large particle size. We used human subjects with ileostomies to investigate the digestion of barley and to determine whether the physical form of barley affects stomal excretion of starch, glucooligosaccharides, nitrogen, fat, and calculated(More)
