Peak expiratory flow mediates the relationship between handgrip strength and timed up and go performance in elderly women, but not men

OBJECTIVE: The aim of the present study was to verify if there is sex difference in the associations among handgrip strength, peak expiratory flow (PEF) and timed up and go (TUG) test results. METHODS: The sample included 288 consecutive elderly men (n=93) and women (n=195). Functional capacity was measured using the TUG test, and muscle strength was measured based on handgrip. Moreover, as a measure of current health status, PEF was evaluated. Linear regression procedures were performed to analyze the relationships between handgrip and both PEF and TUG test results, with adjustment for confounders, and to identify the possible mediating role of PEF in the association between handgrip strength and TUG test results. RESULTS: In men, handgrip strength was associated with both PEF and TUG performance (p<0.01). After adjustment for PEF, the relationship between handgrip strength and TUG performance remained significant. In women, handgrip strength was also associated with both PEF and TUG performance (p<0.01). However, after adjustment for PEF, the relationship between handgrip strength and TUG performance was no longer significant. CONCLUSION: Mobility in the elderly is sex dependent. In particular, PEF mediates the relationship between handgrip strength and TUG performance in women, but not in men

Pacientes transplantados renais: análise de associação dos diagnósticos de enfermagem Pacientes trasplantados renales: análisis de asociación de los diagnósticos enfermeros Kidney transplanted patients: nursing diagnoses association analysis

A insuficiência renal crônica é uma doença com sérias implicações físicas, psicológicas e sócio-econômicas para o paciente. O transplante renal proporciona qualidade de vida aos renais crônicos. O objetivo desse estudo é analisar as associações entre os diagnósticos de enfermagem, os fatores relacionados e as características definidoras presentes em pacientes transplantados renais de um hospital universitário. Um estudo transversal de caráter exploratório e descritivo foi desenvolvido com 58 pacientes entre os meses de dezembro de 2004 e abril de 2005. Os instrumentos de coleta de dados foram: roteiros de entrevista e exame físico. Os resultados mostraram associações entre Padrão de sono perturbado e Disfunção sexual, Padrão de sono perturbado e Padrões de sexualidade ineficazes, Disfunção sexual e Padrões de sexualidade ineficazes. Conclui-se que o estudo contribuiu para a identificação de diagnósticos de enfermagem relacionados a características específicas destes pacientes.<br>La insuficiencia renal crónica es una enfermedad con serias implicaciones físicas, psicológicas y socio-económicas para el paciente.

El objetivo de ese estudio es analizar las asociaciones entre los diagnósticos enfermeros, los factores relacionados y las características definitorias presentes en pacientes trasplantados renales de un hospital universitario. Un estudio transversal de carácter exploratorio y descriptivo ha sido performado con 58 pacientes entre los meses de diciembre de 2004 y abril de 2005. Los instrumentos de recogida de datos fueron: guión de entrevista y examen físico. Los resultados mostraron asociaciones entre Deterioro del patrón de sueño y Disfunción sexual, Deterioro del patrón de sueño y Patrones sexuales inefectivos, Disfunción sexual y Patrones sexuales inefectivos. Se concluye que el estudio aportó para la identificación de diagnósticos enfermeros relacionados a características específicas de estos pacientes.<br>Chronic kidney inadequacy is a disease with serious physical, psychological and socioeconomic implications for the patient. The renal transplant provides life quality to chronic renal patients. The purpose of this study is to analyze associations among nursing diagnoses, related factors and defining characteristics present in renal transplanted patients of a university hospital. A descriptive, exploratory, cross sectional study was performed with 58 patients from December, 2004 to April, 2005. Data collection instruments were: interview scripts and physical exams. Results showed associations between Sleep pattern disturbance and Sexual dysfunction, Sleep pattern disturbance and Altered sexuality pattern, Sexual dysfunction and Altered sexuality pattern. The study contributes for the identification of nursing diagnoses related to specific characteristics of these patients
