Adequate nutrition is of paramount importance in critically ill patients, as it can result in less muscle wasting, decreased length of hospital stay and decreased mortality. Since metabolism, resting energy expenditure (REE) and nutritional status are changing during the different phases of critical illness, it is difficult to ensure adequate nutritional intake. Indirect calorimetry is considered...
Evidence is growing that the individual adjustment of energy targets guided by indirect calorimetry (IC) can improve outcome. With the development of a new generation of devices that are easier to use and rapid, it appears important to share knowledge and expertise that may be used to individualize nutrition care. Despite the focus of this tutorial being on one contemporary device, the principles...
Indirect calorimetry (IC) is the gold standard to monitor energy expenditure in critically ill patients. In several intensive care units (ICUs), nurses are responsible for carrying out the measurements. The aim of this study was to assess nurses' perception of their involvement in IC. This was a prospective survey conducted in the surgical ICU of a French university hospital after 18 months of...
Low energy availability (LEA) describes a state where the energy intake is insufficient to cover the energy costs of both exercise energy expenditure and basal physiological body functions. LEA has been associated with various physiological consequences, such as reproductive dysfunction. However, the effect of LEA on skeletal muscle protein synthesis in females performing exercise training is...
Studies show that malnutrition is common among cancer patients, ranging from about 20% to more than 70%. It is known that malnutrition that is not managed properly worsens the course of the disease, prolongs the hospital stay, and impacts the quality of life and treatment toxicities. Malnutrition has many negative effects, therefore individualization and optimization of nutritional support...
