In comparison to total parenteral nutrition and gut disuse, enteral feeding attenuates disease severity, reduces oxidative stress, and improves patient outcome. Nasojejunal feeds infused at or below the Ligament of Treitz should be provided to those patients with severe pancreatitis, as identified by a number of standardized scoring systems such as Ranson Criteria, APACHE II, Glasgow, and Imrie scores. Total parenteral nutrition should be reserved only for the patient with severe pancreatitis, initiated 4 to 5 days after peak inflammation in whom intolerance to enteral feeding has been shown and/or enteral access cannot be obtained.

{"title":"Medical management of obesity.","authors":"Robert F Kushner","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Obesity is the most prevalent and serious nutritional disease among western countries and is rapidly replacing undernutrition as the most common form of malnutrition in the world. Approximately 300,000 deaths a year are currently associated with overweight and obesity, second only to cigarette smoking as a leading cause of preventable death in the United States. Obesity effects 9 organ systems and is a risk factor for gastroesophageal reflux disease, nonalcoholic fatty liver disease, cholelithiasis, and colon cancer. Evidence-based guidelines on the identification, evaluation, and treatment of overweight and obesity have recently been developed by the National Institutes of Health to help practitioners effectively manage their patients. The body mass index is used to classify weight status and risk of disease. Treatment for obesity includes lifestyle management, consisting of diet therapy, physical activity, and behavioral modification, and may include pharmacotherapy or surgery based on level of risk. Currently only 2 medications, sibutramine and orlistat, are approved for long-term use. An initial weight loss of 10% of body weight achieved over 6 months is a recommended target.

Nutritional chemoprevention of colon cancer. 营养化学预防结肠癌。

{"title":"Nutritional chemoprevention of colon cancer.","authors":"Joel B Mason","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Evidence emerging from many different types of experimental designs continues to support the concept that dietary habits, and nutritional status, play important roles in determining the risk of developing colorectal cancer. Overall, a diet habitually high in fresh fruits and vegetables, modest in calories and alcohol, and low in red meat and animal fat is cancer protective. This field of investigation is nevertheless very confusing, particularly because longstanding hypotheses, such as the presumed protective effects of fruits, vegetables, and fiber, have recently been challenged by well-designed prospective trials. The search for individual components in the diet that convey protection continues: calcium, folate, and selenium are the leading candidates in this regard. There is also growing interest in other plant-based compounds, so-called phytochemicals, although our understanding of their effects is quite rudimentary at present. However, regardless of the constituent components of the diet, evidence continues to accrue that ingesting a sensible amount of calories and maintaining a desirable weight also play important roles in prevention of this cancer. Although the inconsistencies in this field make it tempting to minimize its import, there is little question that diet has a major impact on colorectal cancer risk; diligent attention to the rigorous conduct of studies and their interpretation will likely clarify these relationships over the next decade, much to the benefit of public health.</p>","PeriodicalId":79377,"journal":{"name":"Seminars in gastrointestinal disease","volume":"13 3","pages":"143-53"},"PeriodicalIF":0.0,"publicationDate":"2002-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21990512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A main consequence is malabsorption of macro- and micronutrients.

Intraluminal nutrients and trophic factors are critical for intestinal adaptation. The dietary management is focused on the enhancement of intestinal adaptation and optimal caloric intake. Patients with short-bowel syndrome require an individualized diet, and some may require total parenteral nutrition indefinitely.
