INTRODUCTION Kidney transplantation is currently the treatment of choice for end-stage renal disease. As the successful transplantation improves the physical and mental quality of life, it is expected that the transplant recipient should play a productive role in the society. The present study evaluates the occurrence and predictors of employment after(More)
This study identifies workplace stress according to the Job Stress Scale and associates it with socio-demographic and occupational variables of nursing workers from an emergency hospital. This is a cross-sectional study and data were collected through a questionnaire applied to 388 nursing professionals. Descriptive statistics were applied; univariate and(More)
Guidelines on arterial blood pressure (BP) measurements recommend a time interval between readings. There has been little evidence supporting this recommendation. Therefore, we measured the variation in arterial pressure between the pairs of measurements without an interval (n = 269) or with venous congestion interposed (n = 79). The variation in BP(More)
OBJECTIVES To measure the quality of life (QOL) of patients on RRT with regard to depression, anxiety, and adjustment to illness. MATERIAL The study was conducted between 1996 and 1998 at a teaching hospital in Porto Alegre, Brazil. The study population included 125 patients (transplant n = 64, hemodialysis n = 42 and continuous ambulatory peritoneal(More)
End-stage kidney disease (ESKD) is a major health problem associated with very high morbidity and mortality secondary to cardiovascular complications, especially in ESKD patients on dialysis. Therefore, exploring key mechanisms underlying cardiovascular alterations associated with ESKD may offer reasonable pharmacological targets that may benefit these(More)
BACKGROUND Matrix metalloproteinases (MMPs) play important roles in the pathophysiology of renal diseases, and imbalanced MMP-2 and its endogenous inhibitor (the tissue inhibitor of metalloproteinases-2; TIMP-2) are implicated in the vascular alterations of end-stage kidney disease (ESKD) patients. We have examined whether MMP-2 gene polymorphisms and(More)

L-Arginine is the substrate for nitric oxide synthesis and may enter cells by the y+ and y+ L transport systems. Peritoneal membrane characteristics may depend on vascular function and the L-arginine-nitric oxide pathway. In a cross-sectional study, we evaluated erythrocyte L-arginine uptake in stable peritoneal dialysis (PD) patients with various(More)
