Objective: To evaluate the hydration of obese and non-obese adolescents by vectorial bioimpedance analysis, in addition to verifying the associations between obesity and bioelectrical impedance vectorial analysis (BIVA) parameters. Methods: A cross-sectional study with adolescents between 14 and 18 years old (n=489, 300 boys and 189 girls). Electric bioimpedance (BIA; Quantum_II, RJL system, Rome, Italy) provided resistance and reactance parameters to calculate phase angle (PA), fat-free mass (FFM) and body fat (%BF). The confidence ellipses were compared, and the construction of the tolerance ellipses allowed individual and qualitative evaluation of the vectors and classification in dehydrated, normohydrated and hyperhydrated. Results: 78 obese and 411 eutrophic adolescents participated. Resistance (p<0.001) and reactance (p<0.001) and their normalization by stature (p<0.001) were reduced in the obese, whereas the PA was higher (p=0.003). %BF was 11.3% higher in obese adolescents. The main vector of the obese, both male (D=1.38; p<0.001) and female (D=1.49; p<0.001), indicated greater hydration. The ellipse of tolerance of the total sample showed that 25 (32.1%) were hyperhydrated and 02 (2.6%) vectors positioned in the sense of dehydration. A total of 17 (53.2%) girls and 16 (34.8%) boys were hyperhydrated. Logistic regression showed an inverse relation of BMI with resistance (p<0.001), reactance (p<0.001) and both normalized by stature. Adolescents with increased PA (p<0.001) were twice as likely to present obesity. Conclusions: Obese adolescents were hyperhydrated and there was an inverse relationship of BMI with resistance and direct with PA.

Background Interleukin 6 (IL-6) has an inflammatory effect, and its concentration in serum increases during exercise. However, no studies have assessed acute changes in IL-6 concentration after consecutive days of extreme and long-term exercise. Objective This study aimed to assess acute changes in serum IL-6 concentration during four days of long-distance walking. Methods This prospective observational study assessed 25 athletes (aged 44.8 ± 9.1 years), who covered a total of 251 km in four days. Blood samples were collected daily to assess serum IL-6 concentrations. Repeated-measures analysis of variance (with Bonferroni’s post hoc test) and the Kruskal–Wallis H -test (with Dunn’s post hoc test) were used to investigate the differences between the measures. Results The serum IL-6 concentrations were higher on the four days of walking (1st day: 26.8 ± 14.8; 2nd day: 14 ± 7.4; 3rd day: 9.4 ± 10.8; 4th day: 4.5 ± 0.2 pg/mL) when compared to pre-walk values (pre-walk: 2.2 ± 2.1 pg/mL; p < 0.001). On the first day, there was a tenfold increase compared to the pre-walk value. Conclusion The inflammatory response increased the serum concentration of IL-6 after four days of exercise. With the passing of days, there were reductions but not to baseline values.

RESUMOObjetivo: identificar a qualidade de vida de pessoas com doenças crônicas, internadas em hospitais de Anápolis Goiás. Método: trata-se de uma pesquisa quantitativa, transversal descritiva, utilizando o questionário WHOQOL -bref. Com amostra de 31 pacientes internados em dois hospitais da rede publica de saúde de Anápolis/Goiás com idade 57±1,34 anos, sendo a amostra representada por 15 homens e 16 mulheres, que apresentavam uma ou mais, dos principais tipos de doenças crônicas, sendo elas a hipertensão arterial, diabetes, câncer e doenças cardiovasculares. Foi feita uma análise descritiva dos dados. Resultados: com resultados no domínio físico, a maioria dos indivíduos pesquisados foi classificada com 22,6% "muito ruim" 29% em "ruim"; no domínio psicológico com 32,3% como "nem boa e nem ruim"; no domínio social a maioria já obteve um melhor resultado com 48,4% na classificação "bom"; domínio ambiente com 45,2% "boa" e de acordo com a percepção dos indivíduos a qualidade de vida foi classificada com 41,9% "nem boa, nem ruim". Considerações finais: o estudo identificou que as pessoas com doenças crônicas avaliadas neste estudo, consideram sua qualidade de vida "nem ruim nem boa", principalmente nos aspectos físicos e psicológicos, a doença crônica pode sim, ter afetado a qualidade de vida. Porém, traz resultados satisfatórios no domínio social, como apoio familiar e o domínio ambiente.
