Bioelectrical impedance vector analysis (BIVA) in university athletes [PDF]

Journal of the International Society of Sports Nutrition, 2021
Background Bioelectrical impedance vector analysis (BIVA) is able to identify differences in hydration status and body composition components, such as body cell mass (BCM) by means of plotting individuals in ellipses, when comparing groups with different

Comparison of Bioelectrical Impedance Vector Analysis (BIVA) to 7-point Subjective Global Assessment for the diagnosis of malnutrition

Brazilian Journal of Nephrology, 2021
Introduction: Bioelectrical impedance vector analysis (BIVA) is a non-invasive and low-cost strategy. The methods used to assess malnutrition in patients undergoing HD are still a challenge.

BIVA: A Very Deep Hierarchy of Latent Variables for Generative Modeling

CoRR, 2019
With the introduction of the variational autoencoder (VAE), probabilistic latent variable models have received renewed attention as powerful generative models. However, their performance in terms of test likelihood and quality of generated samples has been surpassed by autoregressive models without stochastic units.

Prognostic value of decreased peripheral congestion detected by Bioelectrical Impedance Vector Analysis (BIVA) in patients hospitalized for acute heart failure: BIVA prognostic value in acute heart failure [PDF]

European Heart Journal: Acute Cardiovascular Care, 2016
The objective of this study was to investigate the prognostic role of quantitative reduction of congestion during hospitalization assessed by Bioelectrical Impedance Vector Analysis (BIVA) serial evaluations in patients admitted for acute heart failure (AHF).AHF is a frequent reason for patients to be admitted.

Mortality in adult patients with fluid overload evaluated by BIVA upon admission to the emergency department

Postgraduate Medical Journal, 2018
AbstractPurpose of the studyThe aim of this study was to investigate the association of fluid overload, measured by bioelectrical impedance vector analysis (BIVA) and also by accumulated fluid balance, with 30-day mortality rates in patients admitted to the emergency department (ED).DesignWe conducted a prospective observational study of fluid overload

Phase Angle and Bioelectrical Impedance Vector Analysis (BIVA) in Amyotrophic Lateral Sclerosis (ALS) Patients

Applied Sciences
Phase angle (PhA) and bioelectrical impedance vector analysis (BIVA) have emerged as valuable tools for assessing nutritional status and prognosis in various patient populations, but there is a lack of studies in rare neurodegenerative diseases.

Appendicular Skeletal Muscle Mass and Sarcopenia as Prognostic Markers in Amyotrophic Lateral Sclerosis. [PDF]

J Cachexia Sarcopenia Muscle
ABSTRACT Background Amyotrophic lateral sclerosis (ALS) is characterized by progressive muscle wasting and functional decline. Prognostic assessment in clinical practice relies largely on functional scales and traditional anthropometric measures. The prognostic relevance of muscle mass, muscle strength and sarcopenia in ALS remains incompletely defined.
