“…The which in the long run can contribute to mortality among these individuals (21) . The greatest advantage of using BCM is that it does not include extracellular water by estimation, which is increased in individuals with chronic renal disease, and frequently causes overestimation of the nutritional value, that is, it may falsely indicate hydration (21) .…”

“…The greatest advantage of using BCM is that it does not include extracellular water by estimation, which is increased in individuals with chronic renal disease, and frequently causes overestimation of the nutritional value, that is, it may falsely indicate hydration (21) . These results can clinically contribute to diet planning, both during intervention and monitoring, aiming to improve patients' nutritional state.…”

OBJECTIVE: to compare the body composition of patients undergoing hemodialysis with that of healthy individuals using different methods. METHOD: cross-sectional study assessing male individuals using anthropometric markers, electrical bioimpedance and vector analysis. RESULTS: the healthy individuals presented larger triceps skinfold and arm circumference (p<0.001). The bioimpedance variables also presented significant higher values in this group. Significant difference was found in the confidence interval of the vector analysis performed for both the patients and healthy individuals (p<0.0001). The tolerance intervals showed that 55.20% of the patients were dehydrated, 10.30% presented visible edema, and 34.50% were within normal levels of hydration. Bioimpedance and vector analysis revealed that 52% of the patients presented decreased cell mass while 14.00% presented increased cell mass. CONCLUSIONS: the differences in the body composition of patients and healthy individuals were revealed through bioimpedance and vector analysis but not through their measures of arm circumference and arm muscle area.

“…Entretanto, a sobrecarga líquida com sinais clínicos discretos ou imperceptíveis pode levar ao subdiagnóstico dessa condição. A Bioimpedância Elétrica (BIA) é um método de avaliação rápido, seguro e não invasivo para avaliação do estado de nutrição e hidratação 9 , sendo importante no estudo das interações entre nutrição e sobrecarga de líquidos.…”

“…Além disso, pacientes deste estudo com maior sobrecarga líquida apresentaram menor ângulo de fase, o qual é tido como marcador de integridade celular 9 . Considerando que esse parâ-metro é influenciado pela idade e pelo sexo 25 , este estudo realizou ajuste para idade, comparando valores de ângulo de fase nos diferentes estados de hidratação, de modo a reforçar a credibilidade do achado.…”

OBJETIVO: Identificar determinantes do estado de hidratação de pacientes em diálise peritoneal crônica, bem como investigar os efeitos da sobrecarga líquida sobre o estado nutricional. MÉTODOS: Foi feito estudo transversal, realizado em 2006, avaliando 27 pacientes em diálise peritoneal crônica, acompanhados no Hospital das Clínicas da Faculdade de Medicina de Botucatu (SP), quanto a parâmetros clínicos, dialíticos, laboratoriais, antropométricos e de bioimpedância elétrica. Para avaliar a influência de parâmetros sobre o estado de hidratação empregou-se modelo de regressão linear múltipla. A amostra foi estratificada quanto ao estado de hidratação pela relação entre água extracelular e água corporal total (0,47 para homens e 0,52 para mulheres), parâmetros obtidos por meio de bioimpedância elétrica. Comparações foram realizadas por análise de covariância, Mann-Whitney, Qui-quadrado ou teste exato de Fisher. Considerou-se significância estatística quando p≤0,05. RESULTADOS: Pacientes com maior volume urinário e em modalidade dialítica automatizada apresentaram melhor estado de hidratação. Pacientes com maior sobrecarga líquida, comparados àqueles com menor sobrecarga, apresentaram menor ângulo de fase (M=4,2, DP=0,9 vs M=5,7, DP=0,7º; p=0,006), menor albumina (M=3,06, DP=0,46 vs M=3,55, DP=0,52g/dL; p=0,05) e maior % prega cutânea tricipital (M=75,3, DP=36,9 vs M=92,1, DP=56,9%; p=0,058), sem outras evidências antropométricas. CONCLUSÃO: Pode-se sugerir que os níveis reduzidos de albumina e ângulo de fase nos pacientes com maior sobrecarga líquida não estiveram relacionados a pior estado nutricional. Para o diagnóstico nutricional em vigência de sobrecarga líquida, deve-se considerar o conjunto de variáveis obtidas por diversos métodos, buscando relacioná-las e interpretá-las de maneira abrangente, possibilitando um diagnóstico nutricional fidedigno.

“…One of them is electrical bioimpedance used for measuring the hydration level [1,2]. Apart from measuring the hydration level, it is also being used for monitoring the adequacy of dialysis (it allows calculation of the total body water volume V, needed for calculating the Kt/V factor), as well as for determining the level of patients' nourishing [3]. It is also being used for assessing the hydration level among peritoneal dialyzed patients, diagnosed with neoplastic diseases, patients after organ transplantations and the ones infected with HIV virus [4].…”

Electric bioimpedance is one of methods to assess the hydrate status in hemodialyzed patients. It is also being used for assessing the hydration level among peritoneal dialysed patients, diagnosed with neoplastic diseases, patients after organ transplantations and the ones infected with HIV virus. During measurements sets were obtained from two groups, which were named a control (healthy volunteers) and test group (hemodialyzed patients). Its variables were the following: body mass index (BMI), intracellular water (ICW) -water volume inside you cells. (i.e., water in the "living" cells), extracellular water (ECW) -water volume outside the body cell mass (i.e., water in the "inactive" cells), total body water (TBW) -sum of ICW and ECW, ECW_TBW -ECW divided by TBW, ECW_mass -ECW divided by body mass, height, weight and age. Zscored, discretized data and data retrieval results were computed in R language environment in order to find a simple rule for recognizing health problems. The executed experiments affirm possibilities of creating good classifiers for detecting a proper patient with the help of medical data sets, but only with previous training.
