Feeding With Indirect Calorimetry and Cycling in the Elderly

The aim of this study is to evaluate the effect of early exercise by cycle ergometry and early targeted feeding in reducing muscle atrophy and improve functional outcomes in the older crit...

Use of Indirect Calorimetry in Obesity

The investigators will retrospectively analyze and compare data of 2 groups of overweight and obese patients: subjects who followed a diet based on Resting Energy Expenditure (REE) measure...

Energy Expenditure in ICU Patients Using Predictive Formulas and Various Body Weights Versus Indirect Calorimetry

Indirect calorimetry is the gold standard to measure energy expenditure. In fact it is not always available and inconstantly feasible. Various equations for predicting energy expenditure b...

The ICALIC International Multicentric Study

This study will evaluate the ease of use of the new calorimeter (Quark RMR 2.0 (COSMED, Italy)) in intensive care unit (ICU) patients compared to currently used calorimeters (i.e. Quark RM...

Validation of Indirect Calorimetry in Children Undergoing Non-invasive Ventilation

Nutritional status in critically ill pediatric patients is considered a fundamental prognostic factor in terms of mortality, morbidity, complications and outcome. Many studies report how p...

Methods for data analysis of resting energy expenditure measured using indirect calorimetry.

The aim of this study was to test the accuracy of different methods of resting energy expenditure (REE) data analysis using indirect calorimetry (IC) during traditional (30 min) and abbreviated (10 mi...

Consistency study of indirect calorimetry and HB equation for measuring energy expenditure of patients with multiple injury receiving mechanical ventilation.

To evaluate the difference and correlation of 24-hour energy expenditure in patients with multiple trauma receiving mechanical ventilation predicted by indirect calorimetry (IC) and HB formula.

Energy Balance in Critically Ill Children With Severe Sepsis Using Indirect Calorimetry: A Prospective Cohort Study.

Energy needs in critically ill children are dynamic and variable. Data on energy balance in children with severe sepsis using indirect calorimetry (IC) is lacking. Thus, we planned to study the energy...

Longitudinal Measurements of Resting Energy Expenditure by Indirect Calorimetry in Healthy Term Infants during the First 2 Months of Life.

 To determine longitudinal measurements of resting energy expenditure (REE) by indirect calorimetry (IC) in healthy term infants during the first 2 months of life.

Test-retest variability of VO2max using total-capture indirect calorimetry reveals linear relationship of VO and Power.

This study aimed to analyze the intra-individual variation in VO2max of human subjects using total-capture and free-flow indirect calorimetry. Twenty-seven men (27±5 year; VO2max 49-79 ml•kg •min...

Medical and Biotech [MESH] Definitions

Calculation of the energy expenditure in the form of heat production of the whole body or individual organs based on respiratory gas exchange.

Method to determine the occurrence of OVULATION by direct or indirect means. Indirect methods examine the effects of PROGESTERONE on cervical mucus (CERVIX MUCUS), or basal body temperature. Direct ovulation detection, generally used in fertility treatment, involves analyses of circulating hormones in blood and ULTRASONOGRAPHY.

Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (FLUORESCENT ANTIBODY TECHNIQUE, DIRECT) or an indirect method, by formation of antigen-antibody complex which is then labeled with fluorescein-conjugated anti-immunoglobulin antibody (FLUORESCENT ANTIBODY TECHNIQUE, INDIRECT). The tissue is then examined by fluorescence microscopy.

The measurement of the quantity of heat involved in various processes, such as chemical reactions, changes of state, and formations of solutions, or in the determination of the heat capacities of substances. The fundamental unit of measurement is the joule or the calorie (4.184 joules). (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)

Differential thermal analysis in which the sample compartment of the apparatus is a differential calorimeter, allowing an exact measure of the heat of transition independent of the specific heat, thermal conductivity, and other variables of the sample.
