Whether to provide artificial enteral nutrition therapy to a patient with evidence of gastrointestinal bleeding (GIB) creates a difficult clinical dilemma. Concern that enteral feeding may contribute to the morbidity associated with GIB leads to delays in initiating enteral therapy or to cessation of feeding in the patient in whom artificial nutrition support has already been started. ⋯ In many cases, an endoscopic evaluation is needed to distinguish the differential etiology of the GIB. The nutrition support specialist needs a full understanding of the physiology behind the varying diagnoses for GIB to know whether feedings can be initiated or continued or whether enteral feedings need to be withheld for 48-72 hours until risk for rebleeding and further morbidity is minimized.

Review Meta Analysis
The role of dietary factors in cancer prevention: beyond fruits and vegetables.
Cancer, a disease resulting from dysregulated cell growth control, is caused by an interaction of dietary, genetic, and environmental risk factors. Dietary factors, including physical activity, may contribute to approximately one-third of all cancers. This meta-review summarizes dietary factor and cancer risk associations and makes specific dietary recommendations to reduce risk of specific cancers. ⋯ We recommend the adoption of dietary patterns emphasizing regular physical activity, fruits and vegetables, whole grains, legumes, nuts, seeds, and low-fat dairy products to all people at risk for cancer and cardiovascular disease. These recommendations may be incorporated into enjoyable cultural food patterns as exemplified by Mediterranean-type diets. The preparation and enjoyment of meals in a convivial atmosphere is a vital component of lifestyles to prevent chronic diseases such as cancer and certain cardiovascular diseases.

Significant weight loss is a common complication of a major burn injury. Before the modern era of early enteral nutrition support, such a complication contributed significantly to impaired wound healing, raised risk of infectious morbidity, and ultimately increased mortality. ⋯ The burn patient characteristically demonstrates an increase in energy expenditure after the initial injury and period of resuscitation. Studies have demonstrated that early institution of enteral feeding can attenuate the stress response, abate hypermetabolism, and improve patient outcome.

Albumin is the predominant product of hepatic protein synthesis and one of the more abundant plasma proteins. Among its multiple physiologic roles, it plays an essential part in the generation of colloid-oncotic pressure. In the United States, the indications for which albumin therapy are considered include hypovolemia or shock, burns, hypoalbuminemia, surgery or trauma, cardiopulmonary bypass, acute respiratory distress syndrome, hemodialysis, and sequestration of protein-rich fluids. ⋯ At the same time, these valuable reviews seem to have documented the advantages of albumin therapy in the management of ascites and clarified the use of albumin in volume resuscitation. More studies have been recommended to investigate the use of albumin in different doses and its role in hypoalbuminemia. This article will provide an overview of albumin metabolism, use of albumin for volume expansion, the potential therapeutic role of albumin in liver disease, and the role of albumin therapy in nutrition.

Proper enteral access to deliver specialized nutrition support in critically injured patients can be difficult, time consuming, and costly. We designed a protocol with interdisciplinary input to facilitate early enteral access in our trauma patients. Our primary objective was to determine if the protocol improved our ability to obtain small-bowel access in patients within 48 hours of their admission to the surgical intensive care unit (SICU). Secondary objectives were to examine the efficacy of the protocol by evaluating parenteral nutrition (PN) use, adequacy of enteral caloric delivery, and clinical outcomes including pneumonia and sepsis rates, SICU length of stay (LOS), hospital LOS, and mortality before and after its implementation. ⋯ The use of a protocol was effective in the achievement of prompt small bowel access. The number of days to reach caloric goal decreased after protocol implementation, but not to a statistically significant degree. However, we were able to detect a significant reduction in the use of PN.
