SP419USEFULNESS OF THE BODY COMPOSITION MONITOR IN SETTING DRY WEIGHT AT AN INITIATION OF HAEMODIALYSIS

The aims of this study in hemodialysis (HD) patients were: 1. To evaluate the relationship of calf bioimpedance with total body composition and fluid status as measured by gold standard methods. 2. To investigate the ability of calf normalized resistivity (CNR) to predict the normal fluid status (dry weight: DW) in a prospective study. In the body composition study (n = 41), fluid status (ECVBr/FFMMRI), muscle mass (MMMRI), and total adipose tissue (TATMRI) were measured by dilution (D2O and Br) and MRI methods three hours prior to HD treatment. Calf extracellular and intracellular resistance, resistivity, and CNR were measured with a multi-frequency bioimpedance device (Hydra 4200). In the fluid status study (n = 32 with 429 measurements), a nonlinear model based on the differences in CNR between patients and healthy subjects was established to predict DWcBIS previously determined by a separate continuous calf bioimpedance spectroscopy (cBIS) method. CNR significantly correlated with a gold standard hydration marker (ECVBr/FFMMRI). Calf body composition models were highly correlated with MMMRI (R2 = 0.85) and TATMRI (R2 = 0.85). DWcBIS prediction was validated with a CNR model in the degree of differences of 0.94 ± 0.18, 0.39 ± 0.7 and -0.02 ± 0.8 kg from DWcBIS when post HD fluid overload was 1.8 ± 1.2, 1.15 ± 0.8 and 0.54 ± 0.5 kg, respectively. These differences are not considered to be clinically significant. Conclusion: This practical method of calf bioimpedance is useful to predict body composition and normal fluid status in dialysis patients.

AbstractThere is an increasing need for suitable tools to evaluate body composition in paediatrics. The Body Composition Monitor (BCM) shows promise as a method, but reference values in children are lacking. Twenty children were included and measured twice by 4 different raters to asses inter- and intra-rater reproducibility of the BCM. Reliability was assessed using the Bland-Altman method and by calculating intraclass correlation coefficients (ICCs). The intra-rater ICCs were high (≥ 0.97) for all parameters measured by BCM as were the inter-rater ICCs for all parameters (≥ 0.98) except for overhydration (0.76). Consequently, a study was set up in which BCM measurements were performed in 2058 healthy children aged 3–18.5 years. The age- and gender-specific percentile values and reference curves for body composition (BMI, waist circumference, fat mass and lean tissue mass) and fluid status (extracellular and intracellular water and total body water) relative to age were produced using the GAMLSS method for growth curves.Conclusion: A high reproducibility of BCM measurements was found for fat mass, lean tissue mass, extracellular water and total body water. Reference values for these BCM parameters were calculated in over 2000 children and adolescents aged 3 to 18 years. What is Known• The 4-compartment model is regarded as the ‘gold standard’ of body composition methods, but is inappropriate for regular follow-up or screening of large groups, because of associated limitations. • Body Composition Monitor® is an inexpensive field method that has the potential to be an adequate monitoring tool.What is New• Good reproducibility of BCM measurements in children provides evidence to use the device in longitudinal follow-up, multicentre and comparative studies.• Paediatric reference values relative to age and sex for the various compartments of the body are provided.

Micropterus Dolomieui

Effects of overwinter starvation on the body composition of young-of-year smallmouth bass (Micropterus dolomieui) were examined in laboratory and field studies. Interactive effects of starvation and low pH on body composition were examined in the laboratory. Changes in body composition associated with starvation were similar in laboratory and field studies: on a dry weight basis, the amount of water, ash, Ca, K, and Na increased progressively in both laboratory and wild fish. The amount of Cl per unit dry weight showed a moderate increase in the laboratory fish and a large decline in the wild fish. The effects on starving fish of 6-wk chronic exposures to nonlethal pH levels of 4.0–7.0 were examined in the laboratory. No pH effect was noted for levels greater than 5.0. Losses of water, ash, Ca, K, Cl, and Na increased as the pH declined. There was no consistent effect of pH on rate of loss of ash-free organic matter. The results suggest that starvation may reduce the tolerance of young smallmouth bass to low pH through progressive weakening of the osmoregulatory system.

Abstract Background and Aims Frailty is known as a biological syndrome of decreased reserves and resistance to stress, with a decline of multiple physiological systems, causing vulnerability. Its prevalence ranges from 10-80 %. The etiopathogenesis is multifactorial, based on the loss of muscle mass associated with aging or sarcopenia. Chronic Kidney Disease (CKD) is a model of accelerated aging, with impaired physical function, frailty and cognitive decline. The main theorical frameworks on frailty are the one advocated by Linda Fried, in which she develops a phenotype as a risk situation for developing disability and one advocated by Kennet Rockwood which establishes that frailty consists of addition of various health conditions including comorbidity and disability. Our objective was to evaluate frailty in stage 5 CKD in haemodialysis, measured by clinical scale and to relate it to the body composition measured by bioimpedance. Method Cross-sectional study in 40 subjects with CKD in hospital haemodialysis, 70.5±13.03 years, 62.5% male. 40% Diabetic Nephropathy, 10% Glomerulopathies, 7.5% Nephroangiosclerosis, 2.5% Chronic Tubule-Interstitial Nephropathies, 32.5% Unknow, 2.5% Others. 35% arteriovenous fistula, 10% arteriovenous graft, 55% central venous catheter. Hemodialysis type: 40% High Flux, 45% Online postdilutional Haemodiafiltration, 10% Acetate Free Biofiltration. Fragility was measured by the Rockwood clinical scale: not fragile (1-4), moderately fragile (5-6) and severely fragile (7-9). Body composition was estimated by monofrequency bioimpedance measurement. Chi-Cuadrado was used to study differences between dichotomous variables and ANOVA for continuous variables. Spearman correlation´s was used to examinate the intensity of association between two quantitative variables. Statistical analysis was performed with SPSS 13.0. Results 42.5% of the subjects presented a degree of fragility ≥5, severely fragile 27.5%. The results are shown in the Tables 1 and 2. Conclusion The degree of frailty is greater in the elderly. Measurement of body composition by bioimpedance can be useful to indirectly asses frailty. The phase angle could be an indicator of fragility, since in more fragile subjects its value decreases, its physiological role remains to be elucidated. There is a positive trend to an increase in extracellular water in more fragile subjects, keeping the subjects in their dry weight, so it will be necessary to evaluate what is due.
