Preliminary results for use of Illness Marker in heart failure patients
Heart failure is characterized by fluid disturbances. Changes in volume in the clinical practice are evaluated with fluid balance and weight measurements, but these do not reflect compartmental changes.
Bioimpedance Illness Marker Compared to Phase Angle as a Predictor of Malnutrition in Hospitalised Patients
Bioelectrical impedance analysis (BIA) is a non-invasive and easily applied technique which is now widely used in clinical settings. The measured impedance to an alternating current comprises reactance, due to the presence of cellular interfaces which lead to capacitive effects, and resistance due to the presence of extracellular and intracellular electrolyte.

Comparing sensitivity of non-invasive markers of volume response to intravenous furosemide in patients with acute pulmonary oedema
Intravenous furosemide (ivF) remains the first line treatment for pulmonary oedema (1) yet individual patient response to ivF is variable (2, 3). There is a need for an accurate, non-invasive means to define volume response to ivF, so that the role of alternative or additional treatments can be addressed.
Bioimpedance index for measurement of total body water in severely malnourished children: Assessing the effect of nutritional oedema
Restoration of body composition indicates successful management of severe acute malnutrition (SAM). Bioimpedance (BI) index (height2/resistance) is used to predict total body water (TBW) but its performance in SAM, especially with oedema, requires further investigation.
Clinical use of bioelectrical impedance analysis in patients affected by myotonic dystrophy type 1: A cross-sectional study
Myotonic dystrophy type 1 (DM1) is an inherited muscle disorder characterized by slowly progressive weakness due to muscle degeneration. The Muscular Impairment Rating Scale (MIRS) is validated to assess clinical muscle severity of patients with DM1, although the scale is not sensitive enough to assess disease progression in time intervals fit for clinical trials. The aim of this study was to analyze bioelectrical whole body and arm segmental parameters in patients with DM1 to explore a correlation between bioelectrical impedance analysis (BIA) parameters and disease stage.
Impedance Ratio: new multi-frequency electrical Bio-impedance functional assessment parameter
Bioelectrical Impedance Analysis (BIA) has been shown to be a simple and practical method of measuring body composition in population studies, provided that specific formulae for each population group are utilized.
Low albumin levels and high impedance ratio as risk factors for worsening kidney function during hospitalization of decompensated heart failure patients
Patients hospitalized for decompensated heart failure (DHF) frequently experience worsening of renal function (WRF), leading to volume overload and resistance to diuretics.

Evaluation of Bioelectrical Impedance Analysis in Critically Ill Patients: Results of a Multicenter Prospective Study
In critically ill patients, muscle loss is associated with adverse outcomes. Raw bioelectrical impedance analysis (BIA) parameters (eg, phase angle [PA] and impedance ratio [IR]) have received attention as potential markers of muscularity, nutrition status, and clinical outcomes. Our objective was to test whether PA and IR could be used to assess low muscularity and predict clinical outcomes.
