BACKGROUND AND AIMS: The phase angle (PA), derived from bioelectrical impedance analysis (BIA), has been interpreted as a cell membrane integrity indicator, while handgrip strength (HGS) has been used as a prognostic indicator in certain clinical situations, such as in cardiac, oncologic patients with renal disease, hemodialysis patients, HIV-positive patients, and liver disease patients. In addition to prognostic scores, body changes due to surgical procedures indicate the importance of measuring muscle function and cell integrity...

Estimation of postmortem interval (PMI) is a critical component of death investigation. A cadaver can be hypothesized to be a resistor-capacitor (RC) circuit the impedance (Z) of which changes in a quantifiable manner as the cadaver decomposes. This hypothesis was tested using bioelectrical impedance analysis (BIA) equipment to apply a current with a fixed amplitude at a single frequency to four cadavers over time and measuring two components of Z, resistance (R) and reactance (Xc ). Quadratic regression analysis between Z and accumulated degree days (ADD) showed a statistically significant parabolic relationship...

INTRODUCTION: Steroid myopathy is a well-known sign of endogenous Cushing's syndrome as well as a side effect of glucocorticoid administration. The clinical finding of muscle weakness and the clinical inspection of the muscle size are the most commonly used diagnostic tools, sometimes in combination with needle electromyography, but there are no means to detect the myopathy before the appearance of clinical or electrodiagnostic signs. Until now, no guidelines have been produced for a disease-specific evaluation of muscle impairment in patients with Cushing's syndrome...

The aim of the work was to determine the effect of body fat change on risk of diabetes in normal glucose tolerance (NGT) population. A total of 1,857 NGT subjects were included and followed up for an average period of 44.57 months. Body fat percentage (BF%) was measured by bioelectrical impedance analysis. Subjects were grouped based on the BF% and/or body mass index (BMI) state. Among all subjects, 28 developed diabetes after follow-up. Compared with subjects with stable normal BF% (control), subjects who became obesity at follow-up were defects in insulin secretion and had a higher risk of developing diabetes (7...

Rheumatoid arthritis (RA) patients frequently have changes in their body composition, with a decrease in muscle mass and an increase in fat mass, a syndrome that is termed rheumatoid cachexia (RC). The prevalence of this nutritional alteration is not well known; there is as yet no consensus, seeing as it depends on the methods, techniques, and cutoff points that are used for its diagnosis. The main aim of this study was to identify RC through assessment by bioelectrical impedance vector analysis (BIVA) and its association with metabolic causes, physical function, and the main disease status, among others...

Nonalcoholic fatty liver disease (NAFLD) commonly occurs in patients with type 2 diabetes mellitus (T2DM). C1q/TNF-related protein-3 (CTRP3) levels are decreased in type 2 diabetic patients. However, to date, it is unknown whether low CTRP3 level are correlated with the incidence of NAFLD. The aim of this study was to observe this association in Chinese patients with T2DM. Overall, 175 newly diagnosed T2DM were recruited in this study. The subjects were divided into NAFLD group (n=93) and control group (n=82)...
