Evolution of the Energy Expenditure During Hematopoietic Stem Cell Transplantation

Evolution of the Energy Expenditure During Hematopoietic Stem Cell Transplantation in Patients With Hematological Disease and Associated Factors

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.

Inclusion Criteria:

• Patients with hematological disease
• Age equal or superior to 15 years old
• Both sexes
• Will be submitted bone marrow transplantation

Exclusion Criteria:

• Age below 15 years old
• Those who can't perform calorimetry (oxygen therapy, mechanical ventilation)
• Have hyper or hypothyroidism
• Admitted to the Intensive Care Unit (without at least one result of post-transplant indirect calorimetry)
• Don't agree to participate in the study
