Evolution of the Energy Expenditure During Hematopoietic Stem Cell Transplantation

The treatment before bone marrow transplantantion is initiated by chemotherapy associated or not with radiotherapy, both of which cause various side effects on the patient as symptoms that impair food intake. The nutritional status of the patient is one of the factors related to the success of the transplant, so a complete nutritional assessment before transplantation is necessary in order to identify patients at nutritional risk, nutritional disorders and to perform appropriate and early intervention to promote recovery and / or health maintenance. Will be used for nutritional assessment: arm perimeter, arm muscle area; electrical bioimpedance, phase angle, and Indirect Calorimetry, a standard method of noninvasive nutritional assessment that expresses the nutritional demand and rate of utilization of energy substrates from oxygen consumption and carbon dioxide production through the air inhaled and exhaled by the individual's lungs.
