Bioelectrical impedance analysis in estimating nutritional status and outcome of patients with chronic obstructive pulmonary disease and acute respiratory failure

Abstract

This study suggests that the decrease in BIA-derived ACM is a good indication of malnutrition and of poor outcome in COPD patients with ARF.

Bioelectrical Impedance Phase Angle as a Prognostic Indicator of Survival in Head-and-Neck Cancer

“…Bioelectrical impedance analysis is a relatively new tool for the assessment of nutrition status; it is useful as diagnostic method both in health and in chronic disease (amyotrophic lateral sclerosis 18 , cirrhosis 25 , hemodialysis 27 , hiv 28 , cancer). An alternative method, bioelectrical impedance spectroscopy, is a technique that measures impedance using 50 or more frequencies; the resulting values are then used to calculate the resistance of the extracellular and intracellular water.…”

“…Reactance is the resistive effect produced by the tissue interfaces and cell membranes 25 . Thanks to its potential to detect changes in tissue electrical properties, pa has been found to be an indicator for cell membrane integrity, distribution of water between the intracellular and extracellular spaces, and prediction of body cell mass in various disease conditions [26][27][28][29][30][31][32][33][34] .…”

Longitudinal follow-up of nutritional status and its influencing factors in adults undergoing allogeneic hematopoietic cell transplantation

“…It is measured by bioelectrical impedance analysis and reflects cell membrane function 15 and indirectly, the body's muscle mass. 16 It is an established parameter for diagnosing malnutrition, and a useful prognostic marker in many clinical conditions 17 including several types of cancer. [18][19][20][21] The Subjective Global Assessment (SGA) questionnaire according to Detsky et al 22 is another means of demonstrating the best combination of sensitivity and specificity in identifying complications related to malnutrition, 23 making the SGA questionnaire a validated tool in cancer patients with which to evaluate nutritional status.…”

The usefulness of anthropometric measures

“…For example, Faisy et al [4] suggested that BIA might be superior to MAMC in predicting malnutrition and negative outcomes among patients with chronic obstructive pulmonary disease and acute respiratory failure. However, as previously demonstrated, MAMC provides a simple measure of body composition.…”
