“…analysis indicated that the values of SCys in men, when determined with nephelometric assay, were slightly but statistically correlated with BCM, which is an indicator of muscle mass [16,28]. As expected, the influence of gender and muscle mass on SCr was much more evident and significant than for SCys.…”

“…Multifrequency BIA was more accurate and less biased than single-frequency BIA for the prediction of ECW [28]. Moreover, in addition to measuring ECW and intracellular water, the multifrequency analysis can be used to estimate muscle and fat masses [29]. …”

Background: This prospective cohort study compared the changes in body water composition and nutritional parameters measured with multifrequency bioimpedance analysis between 8-hour three times weekly nocturnal hemodialysis (NHD) and 4-hour conventional hemodialysis (CHD) patients. Patients and Methods: 55 patients on CHD and 57 patients on NHD were included in the study. Multifrequency bioimpedance analysis was performed at baseline and at the 12th month. The primary outcomes of the study were changes in extracellular water (ECW), fat mass, dry lean mass and phase angle. Secondary outcomes of the study included changes in blood pressure and biochemical parameters related to nutrition and inflammation. Results: ECW/height values decreased in the NHD group, while they increased in the CHD group. Fat mass, dry lean mass, and serum albumin increased and high sensitive CRP decreased in the NHD group but did not change in the CHD group. When changes in parameters from baseline to the 12th month between the groups were compared, NHD was associated with improvement in volume parameter including ECW/height (difference -0.44 l/m, p < 0.001). Change in blood pressure was not different between the groups, however requirement for antihypertensive medication decreased from 26.5 to 8.5% in the NHD group (p = 0.002). NHD was also associated with increases in fat mass (difference 1.8 kg, p < 0.001), dry lean mass (difference 0.6 kg, p = 0.006), serum albumin (difference 0.19 g/dl, p < 0.001) and cholesterol (difference 18.8 mg, p < 0.001). Phase angle values decreased in the CHD group but did not change in the NHD group (difference between the groups 0.37°, p = 0.04). Conclusion: This study revealed that longer HD facilitates volume control and improves nutritional status.

“…Bioimpedance analysis has been used as a tool for body composition/body fat analysis [4][5][6][7][8][9] and in the assessment of fluid imbalance in hemodialysis patients [10][11][12][13]. It has not yet been applied to the prosthetics field.…”

Abstract-We investigated electrical bioimpedance as a potential measurement modality to assess residual-limb volume change in lower-limb amputees. Four strip electrodes were positioned across the anterior lateral to posterior lateral aspects of the proximal lower leg or residual limb such that the outer pair applied current and the inner pair sensed voltage. A commercial bioimpedance analyzer supplied current at 50 frequencies between 5 kHz and 1 MHz and then used a wellvalidated model to determine fluid resistance. From these data, extracellular fluid volume (V ECF ) could be estimated. Bench test evaluation showed the instrument to have a root-meansquare error of less than 0.014% over a 1 h interval. Tests of subjects who had been transtibial amputees for at least 2 yr showed V ECF changes from postural adjustments well outside the instrument error and normal minute-to-minute biological variability. The rate of V ECF change while standing with the prosthesis donned was greater for diabetic subjects than for nondiabetic subjects. Bioimpedance analysis may have use in prosthetics research, where comparing residual-limb volume at different time points or under different treatment conditions is of interest.
