“…According to Neri et al [9], the use of tidal PD optimized catheter ow function, resulting in the presence of < 1 alarm per day (corresponding to < 7 alarms per week). Accordingly, other authors suggest that out ow failure prompts alarms in APD patients treated with HomeChoicePro™ [10]. Moreover, the cut-off value for mean drain time of > 22 minutes for predicting catheter dysfunction found in our study is similar to the conclusion of other authors who suggested that a drainage time of less than 20 minutes is a marker of good catheter performance [3,18].…”

“…Patients with a malfunctioning catheter may clinically present with slow drainage of PD uid, prolonged drain times, poor net UF [6,7] or constant alarms during cycler treatment [10], resulting in impairment of quality of life. Early diagnosis prevents the possibility of volume overload and complications associated with increased intraperitoneal volume that subsequently may lead to technique failure [11].…”

New guidelines on evaluation of peritoneal membrane function recommend ruling out catheter dysfunction when evaluating patients with low ultrafiltration capacity. We introduce the use of a combination of parameters obtained from daily measurements of the cycler software for predicting catheter dysfunction in automated peritoneal dialysis patients. Out of 117 patients treated between 2015 and 2021, all patients with verified catheter dysfunction (n=14) were identified and compared to controls (n=19). We retrieved cycler data for seven days each and tested parameters predictive capability of catheter dysfunction. Total number of alarms/week >7 as single predictive parameter of catheter dislocation identified 85.7% (sensitivity) of patients with dislocated catheter and 31.6% (1-specificity) of control patients. A combination of parameters (number of alarms/week >7, drain time >22 min, ultrafiltration of last fill <150 mL) where at least two of three parameters appeared identified the same proportion of patients with catheter dislocation, but was more accurate in identifying controls (21% false positive). An easily applicable combination of daily cycler readout parameters, also available in remote monitoring platforms can be used as predictor of inadequate catheter function during routine follow-up with potential for earlier diagnosis of this frequent complication in the future.

“…Last generation cyclers incorporate intra-peritoneal pressure (IPP) control, (pump-driven) inflow/outflow rate sensor, possibility to vary PDF composition, volume and dwell duration on a cycle by cycle basis during a session, giving room to better comfort for patients and caregivers while enhancing dialytic efficiency. 9 Technological innovation has also made remote monitoring possible, with the advantage of closer, real time follow up. It has been found to improve patient's adherence to prescribed therapy, to enhance timely recognition of complications and proactive intervention, to reduce patient's unscheduled access to the hospital and to promote dialysis adequacy.…”

A steadily increasing number of end stage kidney disease (ESKD) patients are maintained on automated peritoneal dialysis (APD) worldwide, in long-standing as well as in more recently established peritoneal dialysis (PD) programs. A better understanding of the technique, paralleled by progress in involved technology, sustained this growth to the point that APD has become the prevalent mode of PD delivery in most high-income countries. While APD is now regarded to be at least as efficient as continuous ambulatory peritoneal dialysis (CAPD) with regard to major biomedical outcomes, its impact on patient-reported outcomes has been less investigated. This paper reviews the main outcomes of APD from a clinical point of view and from the person on dialysis perspective.

“…Currently, the common treatments for uremia include kidney transplantation, hemodialysis(HD), hemoperfusion(HP) and peritoneal dialysis(PD) [3,4]. Despite many advances in the field of renal replacement therapy [5], patients still need long-term and frequent blood purification treatment in hospitals [6,7], which prevents them from returning to the society and restricts their personal freedom, which makes ESRD patients gradually marginalized by society and become a heavy burden to their families [8,9].…”

End-stage renal disease is a global health issue, and there is a growing trend of younger individuals being affected by this condition. In order to save time for patient undergoing dialysis treatment and allow them to return to social life, a portable dialysis device called wearable artificial kidney is quite necessary. The dialysate recycling system serves as a fundamental component of the wearable artificial kidney. It effectively eliminates various toxins from the waste dialysate and gets regenerated dialysate for subsequent dialysis sessions. However, the low capacity of urea treatment has been a difficult problem to overcome. In this study, our primary focus was to investigate the optimal modification conditions for activated carbon modified with sulfuric acid. We fabricated water vapor activation of coconut shell activated carbon and modified activated carbon of various mesh sizes with sulfuric acid solution. The samples were subjected to characterization, and adsorption experiments were conducted to evaluate their performance in adsorbing creatinine and urea. It was ultimately concluded that the samples obtained by treating 200 mesh activated carbon with 6 mol/L sulfuric acid solution exhibited superior adsorption capacity.
