Cross-cultural validation of the Portuguese version of the Dialysis Symptom Index for haemodialysis patients.

Background: Patients with end-stage renal disease (ESRD) undergoing haemodialysis (HD) are associated with low quality of life (QoL) and high disease-related symptoms. The patient self-report instruments can assess the burden of physical and psychological symptoms. The Dialysis Symptom Index (DSI) is a specific instrument to evaluate the multidimensional reported symptoms by patients undergoing HD.

Skin pigmentation as landmark for arteriovenous fistula cannulation in hemodialysis.

Background: The cannulation of the arteriovenous fistula (AVF) for hemodialysis (HD) has traditionally depended on the nurse's tactile sensation, which has been associated with suboptimal needle placement and detrimental effects on vascular access (VA) longevity. While the introduction of ultrasound (US) has proven beneficial in mapping the AVF outflow vein and assisting in cannulation planning, aneurysmal deformations remain a common occurrence resulting from various factors, including inadequate cannulation techniques. Within this context, the utilization of skin pigmentation as a clinical landmark has emerged as a potential approach to enhance cannulation planning in HD.

Cross-cultural validation of the Short-Form Vascular Access Questionnaire.

Background: Vascular access (VA) is a central condition for hemodialysis (HD). Screening patients' views regarding their VA is a significant end point for improving the quality of care. The Short-form Vascular Access Questionnaire (SF-VAQ) is a specific questionnaire to assess patients' satisfaction levels regarding their VA.
