Bioelectrical phase angle and impedance vector analysis - Clinical relevance and applicability of impedance parameters
The use of phase angle (PhA) and raw parameters of bioelectrical impedance analysis (BIA) has gained attention as alternative to conventional error-prone calculation of body composition in disease. This review investigates the clinical relevance and applicability of PhA and Bioelectrical Impedance Vector Analysis (BIVA) which uses the plot of resistance and reactance normalized per height.
Phase angle as a marker for sarcopenia in cirrhosis
In patients with cirrhosis nutritional disturbances can progress to sarcopenia, worsening the disease prognosis. Phase angle (PA) may be a useful marker for sarcopenia in this clinical population reflecting the cellular integrity level. This cross-sectional and prospective study evaluated the association between low PA values and clinical/nutritional variables in cirrhosis with emphasis on sarcopenia.
Risk, Prevalence, and impact of hospital malnutrition in a Tertiary Care Referral University Hospital: a cross-sectional study
Hospital malnutrition is still underestimated among physicians, even in internal medicine settings. This is a cross-sectional study, aiming to estimate the risk, the prevalence and the impact of malnutrition in an Internal Medicine and Gastroenterology Department of a large Italian hospital (Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome).
Bioelectrical impedance analysis (BIA)-derived phase angle (PA) is a practical aid to nutritional assessment in hospital in-patients
Nutritional status can be difficult to assess. Bioelectrical impedance analysis (BIA)-derived phase angle (PA), and the plasma markers citrulline and transthyretin (pre-albumin) have the potential to assist, but the protocol of fasting and resting for BIA renders the investigation impractical for routine use, especially so in populations at high risk of malnutrition.
Phase angle obtained by bioelectrical impedance analysis independently predicts mortality in patients with cirrhosis
To evaluate the prognostic value of the phase angle (PA) obtained from bioelectrical impedance analysis (BIA) for mortality prediction in patients with cirrhosis.
A new option in measuring bioimpedance in congestive heart failure
We read with particular attention the interesting article of Tang and Tong concerning the measurement of impedance for assessing volume status in heart failure (HF). This technology is useful in detecting subclinical congestion and predicting future HF events. However, the authors have focused their attention only on central fluid overload. To this proposal, we would briefly discuss about a new promising method, not mentioned in the critical review, able to measure whole-body overload.
Bioelectrical Impedance Phase Angle: Utility in clinical practice
The choice of the best nutrition assessment method in hospitalized patients remains a challenge. The aim of this study was to review the use of phase angle (PA) in clinical practice.
Bioelectrical impedance analysis in clinical practice: a new perspective on its use beyond body composition equations
The bioelectrical impedance analysis is not a direct method for estimating body composition. Its accuracy depends on regression equations, and recent papers have suggested that this approach should not be used in several clinical situations. Another option is to obtain information about the electrical properties of tissues by using raw bioelectrical impedance measurements, resistance and reactance. They can be expressed as a ratio (phase angle) or as a plot (bioelectrical impedance vector analysis). This review
describes their use in clinical practice.
Cereals and pulse-based ready-to-use therapeutic food as an alternative to the standard milk- and peanut paste–based formulation for treating severe acute malnutrition: a noninferiority, individually randomized controlled efficacy clinical trial
The cost of current standard ready-to-use therapeutic food (RUTF) is among the major obstacles to scaling up community-based management of acute malnutrition (CMAM), an important child survival strategy. Identifying a cheaper alternative is a global public health priority.
