Os parâmetros não tradicionais derivados da bioimpedância elétrica (BIA) como reatância, ângulo de fase e massa celular estão cada vez sendo mais utilizados na prática clínica para auxiliar no diagnóstico nutricional dos pacientes com doença renal crônica e, consequentemente, no prognóstico clínico dessa população. O presente estudo teve por objetivo avaliar a relação dos parâmetros derivados da BIA com o estado nutricional de pacientes em hemodiálise. Estudo transversal, realizado com trinta pacientes adultos de uma clínica de Nefrologia localizada na região metropolitana de São Paulo. Foi utilizada a BIA para avaliar esses parâmetros, assim como para avaliar a composição corporal. A amostra foi constituída por homens e mulheres com média de idade de aproximadamente 56 anos. O ângulo de fase dos pacientes foi de 5,9±1,6 graus e apresentou uma correlação negativa com idade (r= -0,69, p< 0,001) e água corporal extracelular (r= -0,93 p< 0,001). A média de reatância foi de 50,9±16,08 ohms e apresentou correlação negativa com a água extracelular (r= -0,82, p<0,001) e positiva com a massa celular (r=0,51, p<0,004). Em relação ao percentual de massa celular, a média foi de 36,8± 6,1%, sendo que a mesma apresentou uma correlação negativa com a idade (r= -0,66, p< 0,001), gordura corporal (r= -0,73, p< 0,001), água corporal extracelular (r= -0,82, p<0,001).Conclui-se que os parâmetros não tradicionais derivados da BIA apresentaram boa associação com o estado nutricional dos pacientes, podendo dessa forma, serem aliados importantes para obtenção do melhor diagnóstico nutricional e, consequentemente, do prognóstico dos mesmos durante o tratamento dialítico.Palavras-chave: Bioimpedância Elétrica.

The present study aimed to evaluate the relationship of parameters derived from the BIA with nutritional status of hemodialysis patients. It was a cross-sectional study with 30 adultspatients of a nephrology clinic in the metropolitan region of São Paulo. BIA was used to evaluate as well as to assess the body composition. The mean age of the patients was approximately 56 years. The phase angle of the patients was 5.9 ± 1.6 degrees and it was negatively correlated with age (r = -0.69, p <0.001) andwith extracellular body water (r = -0.93 p <0.001). The mean reactance was 50.9 ± 16.08 ohms and it showed a negative correlation with the extracellular water (r = -0.82, p <0.001) and positively with the body cell mass (r = 0.51, p <0.004). Regarding to the percentage of body cell mass, the mean was 36.8 ± 6.1%, and it presented a negative correlation with age (r = -0.66, p <0.001), body fat (r = -0.73, p <0.001) and with body water extracellular (r = -0.82, p <0.001). The present study concluded that non-traditional parameters derived from BIA showed a good association with the nutritional status of hemodialysis patients. It is important for getting the best nutritional diagnosis and consequently the prognosis of these patientsduring the dialysis treatment.Keywords: Bioelectrical Impedance. Nutritional Status.

AbstractPrevious studies on the association between thyroid function and body composition are conflicting and showed strong differences across age groups. Our aim was to clarify age-specific associations of serum thyroid-stimulating hormone (TSH) levels with markers of body composition including body mass index (BMI), waist circumference, fat mass (FM), fat-free mass (FFM) and body cell mass (BCM). We used data from two independent population-based cohorts within the framework of the Study of Health in Pomerania. The study population included 5656 individuals aged 20 to 90 years. Markers of body composition were measured by bioelectrical impedance analysis. Serum TSH levels were significantly positively associated with BMI (β = 0.16; 95% confidence interval [CI]: 0.06 to 0.27), waist circumference (β = 0.35; 95% CI: 0.08 to 0.62) and FM (β = 0.32; 95% CI: 0.12 to 0.52), but not with FFM and BCM. Interaction analysis revealed positive associations of serum TSH levels with BMI, waist circumference, FM, FFM and BCM in individuals older than 60 years, while no such associations were observed in younger individuals. We demonstrated that lower serum TSH levels were accompanied with lower values of BMI, waist circumference, FM, FFM, and BCM in the elderly, while no such associations were observed in younger individuals.

Summary Objective: The aim of our study was to assess body composition status and its association with inflammatory profile and extent of intestinal damage in ulcerative colitis patients during clinical remission. Method: This is a cross-sectional study in which body composition data (phase angle [PhA], fat mass [FM], triceps skin fold thickness [TSFt], mid-arm circumference [MAC], mid-arm muscle circumference [MAMC], adductor pollicis muscle thickness [APMt]), inflammatory profile (C-reactive protein [CRP], a1-acid glycoprotein, erythrocyte sedimentation rate [ESR]) and disease extent were recorded. Results: The mean age of the 59 patients was 48.1 years; 53.3% were women. Most patients were in clinical remission (94.9%) and 3.4% was malnourished according to body mass index. PhA was inversely correlated with inflammatory markers such as CRP (R=-0.59; p<0.001) and ESR (R=-0.46; p<0.001) and directly correlated with lean mass: MAMC (R=0.31; p=0.01) and APMt (R=0.47; p<0.001). Lean mass was inversely correlated with non-specific inflammation marker (APMt vs. ESR) and directly correlated with hemoglobin values (MAMC vs. hemoglobin). Logistic regression analysis revealed that body cell mass was associated with disease extent (OR 0.92; 95CI 0.87-0.97; p<0.01). Conclusion: PhA was inversely correlated with inflammatory markers and directly correlated with lean mass. Acute inflammatory markers were correlated with disease extent. Body cell mass was associated with disease extent.
