A study in the Journal of Medical Technology and Physical Therapy investigates the variability of Resting Energy Expenditure in hemodialysis patients. Hemodialysis procedures of a long duration of 3–4 h may possibly affect resting energy expenditure (REE), leading to post-dialysis symptoms in chronic kidney disease (CKD). The purpose of this stud…

The role of predicitve equations versus indirect calorimetry in patients treated for bipolar disorder has been investigated in this study published on the Official Journal of the Italian Society of Psychopathology. The purpose of this study was to compare predictive formulae (Harris-Benedict, Mifflin-St. Jeor and LARN) commonly used to calculate…

A new study published on the Proceedings of the Nutrition Society focuses on energy expenditure after spinal cord injury (SCI) and how commonly used predictive equations tend to overestimate resting metabolic rate (RMR) by 5–32 %. The objective of this study was to measure RMR (m-RMR) with an indirect calorimeter (Quark RMR) and then compare the…

The importance of measuring and not estimating Resting Energy Expenditure has been confirmed also for critically ill cardiac patients in a pilot trial published on Heart Lung Vessel Journal. The aim of present pilot trial was to evaluate the actual resting energy expenditures (REE) among haemodynamically compromised cardiac patients. The study c…

A new study on Critical Care Journal describes international nutrition support practices in critically ill head-injured patients. Given that critical illness following head injury is associated with a hypermetabolic state, the study major finding was that nutritional deficits are commonplace and these deficits are associated with a delay to disch…

This study published in the Journal of Neonatal-Perinatal Medicine, investigates metabolic changes and nutritional needs during the postsurgical anabolic phase in infants. This analysis explores the associations of resting energy expenditure (REE) and macronutrient utilization with body composition of full-term infants, during catch-up growth aft…

The importance of measuring Resting Energy Expenditure through Indirect calorimetry has been examined and confirmed in a study published on the ASPEN Nutrition in Clinical Practice Journal. Critically ill patients often require nutrition support, but accurately determining energy needs in these patients is difficult. Energy expenditure is affecte…

The updated Guidelines by Society of Critical Care Medicine (SCCM) and American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.) were published in beginning of 2016 on the Journal of Parenteral and Enteral Nutrition. This particular report is an update and expansion of guidelines published by A.S.P.E.N. and SCCM in 2009. The intended use…

A new study published on American Journal of Critical Care confirms the scarce accuracy of REE predictive equations and the importance of REE measurement through indirect calorimetry. The aim of the study was to compare resting energy expenditure measured by indirect calorimetry (REEIC) with REE calculated by using the Harris-Benedict equation wi…

A new study on Quark RMR was published in Germany validating the its accuracy for REE measurements and its test-retest reliability. The aim of this study was to verify the quality criteria for the determination of REE with Quark RMR. The following questions are answered: - Can the quality criteria identified by Compher et al (2006) be applied in…

A new clinical validation for Fitmate RMR measurement versus the Deltatrac in nonventilate patients was published on "Nutrition - The International Journal of Applied and Basic Nutritional Sciences". The aim of this study was to assess the validity and reliability of the Fitmate metabolic system in measuring the oxygen consumption and resting met…

A new study demonstrates that Fitmate used to measure resting metabolic rate is a valid and reliable device. The purpose of this study, presented during the 11th International Society of Sports Nutrition (ISSN) Conference (Clearwater Beach, FL, USA. 20-21 June 2014), was to establish the inter- and intra-day test-retest reliability of the Cosmed…

A new validation study on Quark RMR was published by Pennsylvania State University researchers on the Journal of Parenteral and Enteral Nutrition (JPEN). A prospective, observational, N-of-1 trial was conducted to validate COSMED Quark RMR, a new-generation indirect calorimeter against Deltatrac, the gold standard device that is no longer manufac…

A new study from the Polish Warsaw University of Life Sciences (WULS – SGGW) assesses the validity of Fitmate PRO in measuring energy expenditure at rest of obese women. The aim of the analysis was to present the possibilities of using the Fitmate PRO monitor in the assessment of resting metabolic rate and basal energy expenditure with a method o…

A study by the Australian Alfred Hospital focused on the importance of the measurement of Resting Energy Expenditure of burn patients using indirect calorimetry. The aim of this retrospective observational study was to compare the accuracy of three predictive equations used for measuring energy expenditure (EE) to Indirect Calorimetry. Trained di…

A study by the Swedish Karolinska Instituet has been published on Clinical Nutrition Journal showing excellent results for Quark RMR in measuring indirect calorimetry in mechanically ventilated patients.  The study objectives were focused on the necessity of validating new instruments for indirect calorimetry in mechanically ventilated patients…

A new study has been published to evaluate selected factors influencing resting energy expenditure (REE) in obese female subjects. The study, published on the June issue of the World Journal of Experimental Medicine, was carried out by the Department of Experimental Medicine, Medical Physiopathology, Food Science and Endocrinology Section, Food S…

The measurement of Resting Metabolic Rate using the Fitmate with a ventilated canopy hood was validated by a study presented during the 2012 ACSM Annual Meeting. The study, by the Northern Illinois University, aimed to determine the reliability and validity of measuring resting metabolic rate (RMR) with COSMED’s FitMate™ metabolic system using a…

A French study examined the reproducibility of the Fitmate metabolic system in measuring breathing gas during a cycling exercise. The study (in French language), by the University of Nice Sophia-Antipolis, aimed to demonstrate the reproducibility of respiratory variables (VE and VO2) using a desktob metabolic system like Fitmate. Twenty-one part…
