Purpose: In a monocentric retrospective study, two tunneled hemodialysis catheters have been compared: a twin cylinder catheter (Dualcath) and a split tip catheter (Hemosplit).
Patients And Methods: Patients who got catheters from January 1st 2007 to December 31st 2008 have been selected. Thrombotic events, as well as infectious events, were recorded in their dialysis file during this period of time.
Main Results: The study was carried out on 50 patients. Thirty of them were given Dualcath, 23 were given Hemosplit, and three both of them. A Kaplan-Meier analysis has enabled to draw up the catheter survival curves, and the log-rank test enables to establish a survival of 93.1% at 20 months for Dualcath while 42.2% for Hemosplit. As far as the thrombotic complications with catheter incident are concerned, their incidence is 25.5 and 46.4 out of 1000 catheter-days (P<0,0001). The ones with catheter manipulation have incidences of 6.78 and 9.33 out of 1000 catheter-days, respectively for Dualcath and Hemosplit (NS). Dualcath presents catheter-related infections with a rate of 4.38 out of 1000-catheter days while 5.07 for Hemosplit (NS).
Conclusion: The Dualcath catheter presents a better survival than the Hemosplit catheter as well as weaker incident type thrombotic complications.

A 73-year-old Japanese man with chronic kidney disease had no history of abnormal clotting or bleeding. Six days after receiving his third dose of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine (BNT162b2; Pfizer/BioNTech), blood tests showed a marked prolongation of the prothrombin time-international normalised ratio and activated partial thromboplastin time, as well as a decrease in factor V (FV) activity. Three months later, he required dialysis owing to worsening heart and renal failure.

Background: The challenges posed by difficult intravenous access (DIVA) in clinical treatment are not only related to technical difficulties but also have the potential to affect the quality of patient care and overall experience. It is crucial to adopt effective strategies to address difficult intravenous access. Currently, the assessment of difficult veins largely relies on individual perception and experience, which introduces a significant degree of subjectivity.

Background: Globally, haemodialysis is the most frequent type of kidney replacement therapy and necessitates access to the bloodstream either through a native arteriovenous fistula, arteriovenous graft or central venous catheter. Vascular access complications are a major cause of morbidity and mortality in adults receiving haemodialysis, and effective vascular access self-management is required.
Objective: To examine the effectiveness of educational or behavioural interventions designed to improve self-management of long-term vascular access in adults receiving haemodialysis.

Background: Nursing sensitive indicators are a way of measuring aspects of patient care that are most affected by the actions of the nurse. Despite the existence of nursing sensitive indicators, these are largely not suitable to measure peritoneal dialysis nursing practice.
Objective: This project aimed to co-develop a set of peritoneal dialysis nursing-sensitive indicators.
