Presented and described in detail is a clinical technique called subjective global assessment (SGA), which assesses nutritional status based on features of the history and physical examination. Illustrative cases are presented. To clarify further the nature of the SGA, the method was applied before gastrointestinal surgery to 202 hospitalized patients. The(More)
BACKGROUND & AIMS We evaluated CDP571, a humanized antibody to tumor necrosis factor, for the treatment of active Crohn's disease. METHODS One hundred sixty-nine patients with moderate-to-severe Crohn's disease were enrolled in a 24-week placebo-controlled trial. Patients were initially randomized to a single dose of 10 or 20 mg/kg CDP571 or placebo to(More)
We studied 202 patients admitted to two major teaching hospitals for planned gastrointestinal surgery to assess the ability of several techniques of nutritional assessment to predict major postoperative complications (infection and/or wound problems). Subjective global assessment (SGA) and albumin were both of predictive value, and combinations of these(More)
BACKGROUND The colonic mucosa is highly dependent upon the presence of luminal nutrients. This dependence is most marked in the distal colon. The major luminal nutrients are short chain fatty acids that are produced as a by-product of colonic fermentation of carbohydrates. Butyrate appears to be the short chain fatty acid most avidly metabolized by the(More)
Herein we describe a methodology which can be used to evaluate the predictive accuracy of nutritional assessment techniques. We use this methodology to compare seven techniques of nutritional assessment in terms of their ability to predict one nutrition associated hospital complication (infection) by dividing a sample of 59 surgical patients into high risk(More)
The dependence of phrenic efferent discharge on vagal-volume feedback was examined in barbiturate-anesthetized, paralyzed cats ventilated by a phrenic-driven servo respirator. The characteristics of the respiratory were altered for a single breath, and the resulting change in phrenic activity was quantitated by comparison with phrenic activity without(More)
OBJECTIVE To examine the effect of selective antibiotic decontamination of the digestive tract in patients undergoing elective orthotopic liver transplantation. DESIGN Prospective, randomized, concurrent allocation to either selective decontamination or standard antibiotic prophylaxis. SETTING Operating theater and intensive care unit at a tertiary(More)
