An ion-selective electroanalyzer for bio-electrochemically controlled hemodialysis will be described. The bedside analysers are solid-contact flow-through electrodes based on tubular carrier-PVC-membranes for potassium, sodium, calcium and chloride. This multi-measurement system with series-connected biosensors in modular construction is provided with a chemosensor for pH measurements. Besides the technical aspects of the apparatus, the quantitative electrode characteristics and the fundamental basis for the application of ion activities in clinical analytic measurement will be described.

Stenosis within the arteriovenous fistula (AVF) of hemodialysis patients leads to vascular access dysfunction and inadequate hemodialysis. Percutaneous transluminal angioplasty (PTA) is the standard therapy for stenosis. However, rates of restenosis and loss of access patency remain high.

Physical Activity (PA) provides numerous biological and psychological benefits, especially for cancer patients. PA mitigates treatment side effects, influences hormones, inflammation, adiposity, and immune function, and reduces symptoms of anxiety, depression, and fatigue. This study evaluates the impact of PA on these positive outcomes.

Managing periprosthetic femoral fractures is challenging, particularly in osteoporotic patients with fragile bones. Revision with a long stem is commonly considered but may fail to provide adequate fixation and stability in fragile bones. A novel approach using sandwiched strut allografts and controlled bone crushing with robust cable fixation can offer mechanical support and provide secondary stability to the loosened femoral stem and can be considered a treatment option for low-demand patients.

: Bone and mineral disease (BMD) is a prevalent complication of advanced chronic kidney disease (CKD). The risk of fractures can be assessed via dual-energy X-ray absorptiometry (DXA) and quantitative computed tomography (QCT). This study aims to evaluate the effectiveness of two imaging modalities in identifying bone mineral status in individuals with pre-dialysis chronic renal disease and to assess their correlation with bone turnover markers.

Background: Despite an epidemic of End-Stage Kidney Disease in the Australian Aboriginal and Torres Strait Islander population, disparities in access to kidney transplantation persist. The journey to successful kidney transplant is long, with an initial suitability assessment required before waitlist-specific activities begin. In an Aboriginal Community Controlled renal service, we aimed to: 1.
