Further, patients with the greatest functional impairment had significantly higher levels of APB (p = 0.005), PEP (p = 0.005), ASP (p = 0.006), GLU (p = 0.020), and PGAP (p < 0.001) activity, though not of NAP or PSA, indicating local alterations in the renin-angiotensin system. A binary logistic regression model showed that PSA was protective (p = 0.005; Exp (B) 0.949), whereas PEP (p = 0.005) and GLU were risk factors (p = 0.012). These results suggest synovial fluid peptidase activity could play a role as a measure of disease burden and predictive biomarker of progression in KOA. Cite this article 2020;9(11)789-797.

However, burnout - defined as mental, emotional, or physical exhaustion that leads to thoughts of discontinuing PD - is associated with an increased risk of transfer to HD. We aimed to describe the perspectives of burnout among patients on PD and their caregivers. In this focus group study, 81patients and 45 caregiversparticipated in 14 focus groups from 9 dialysis units in Australia, Hong Kong, and the United States. Transcripts were analyzed thematically. We identified two themes. contributed to burnout, as patients and caregivers felt overwhelmed by the daily regimen, perceived their life to be coming to a halt, tolerated the PD regimen for survival, and had to bear the burden and uncertainty of what to expect from PD alone. against burnout encompassed establishing a new normal, drawing inspiration and support from family, relying on faith and hope for motivation, and finding meaning in other ac
