Different kidney function trajectory patterns before dialysis in elderly patien...

Background. Identifying trajectories of kidney disease progression in chronic kidney disease (CKD) patients may help to deliver better care. We aimed to identify and characterize trajectories of renal function decline in CKD patients and to investigate their association with mortality after dialysis.Methods. This retrospective cohort study included 378 CKD patients who initiated dialysis (aged 65 years and over...

Urgent-Start Peritoneal Dialysis – a viable option? A case report and literatur...

Background: Many patients with end -stage renal disease start renal replacement therapy in an unplanned manner. The vast majority initiate hemodialysis by a central venous catheter, since its use is more widespread and available. This technique is associated with a high risk of infection and damage of the vascular patrimony associated with the use of central veins. Urgent -start peritoneal dialysis comes as an ...

Predicting 6-Month Mortality in Incident Elderly Dialysis Patients: A Simple Pr...

Aim: Mortality in end-stage renal disease (ESRD) remains high, particularly among elderly, who represents the most rapidly growing segment of the ESRD population in wealthier countries. We developed and validated a risk score in elderly patients to predict 6-month mortality after dialysis initiation. Methods: We used data from a cohort of 421 patients, aged 65 years and over who started dialysis between 2009 an...

End-stage renal disease versus death in a Portuguese cohort of elderly patients...

Chronic kidney disease (CKD) is higher in elderly, but mortality outweighs the risk of end-stage renal disease (ESRD). Our aim was to identify prognostic markers for ESRD or death in elderly CKD, within a competing-risk analysis. This is a longitudinal study of consecutive newly referred patients with CKD ages 65 years, followed until the time of the first event (ESRD or death), using a competing-risk analysis....

Better outcomes of peritoneal dialysis in diabetic patients in spite of risk of...

Introduction: Diabetes mellitus is a leading cause of chronic renal failure, challenging therapy strategies. Patients with diabetes may benefit from peritoneal dialysis (PD) but higher technique failure is feared. Our purpose was to critically evaluate clinical outcomes of this modality in diabetics, in order to find quality improvement strategies in these risk patients. Methods: A registry-based study of 432 i...

Modelling competing risks in nephrology research: an example in peritoneal dial...

Background: Modelling competing risks is an essential issue in Nephrology Research. In peritoneal dialysis studies, sometimes inappropriate methods (i.e. Kaplan-Meier method) have been used to estimate probabilities for an event of interest in the presence of competing risks. In this situation a competing risk analysis should be preferable. The objectives of this study are to describe the bias resulting from th...

Efeito de Hidroxietilamido sobre Lesão Renal Aguda em Modelo de Isquemia-Reperf...

BACKGROUND: Hepatic vascular control techniques employed during liver surgery are usually associated with ischemia-reperfusion injury, which could cause acute renal dysfunction. The murine model has been used in the study of this injury. Hydroxyethyl starch has recognized anti-inflammatory properties and improves microcirculation. Third generation hydroxyethyl starches, namely 130/0.4, show a better safety prof...

Temporal trends in peritonitis rates, microbiology and outcomes: The major clin...

Peritonitis remains a common complication of peritoneal dialysis (PD). The aim of this study was to analyze, in a PD center, long-term temporal trends in peritonitis rates, microbiology and outcomes. We treated 588 cases of peritonitis that occurred during 11,833.6 months at risk. Y-set and twin-bag disconnecting systems were introduced in 1990, mupirocin at the exit site in 2000 and fluconazole prophylaxis in ...
