Randomized Controlled Trial Clinical Trial
A cost-evaluation of glutamine-supplemented parenteral nutrition in adult bone marrow transplant patients.
In a randomized, double-blind, prospective clinical trial, we evaluated the metabolic effects of glutamine-supplemented parenteral nutrition in patients with bone marrow transplants. We compared hospital charge and cost data for the two groups of patients in the trial. ⋯ This intervention study using a new therapy demonstrated clinical and nutritional benefits to patients and cost savings to the hospital.

Obstructive sleep apnea (OSA) is a common disorder in which upper-airway obstruction during sleep results in cessation of breathing. OSA is associated with increased morbidity and mortality and impaired daytime functioning. Upper-body obesity is a risk factor for OSA, and it is well documented that weight loss has a notable ameliorative impact on the occurrence of OSA. ⋯ In moderately obese patients, modest weight reduction may alleviate the need for long-term nCPAP therapy or upper-airway surgery. Severely obese patients usually require more substantial weight loss and may be candidates for behavioral therapy in combination with gastric surgery. The role of the dietitian in the treatment of OSA cannot be overemphasized and warrants further development and study.
