Abstract

In the peritoneal dialysis, it is well-known that the peritoneal permeability increases gradually over the duration of treatment. The enhancement of the peritoneal permeability causes an under-dialysis and ultrafiltration failure, which is one of the grave factors which disrupt the homeostasis of body fluid. Hence, the monitoring of the peritoneal permeability is very important in order to give each patient some better prescriptions. In this study, we designed a novel criterion which can evaluate quantitatively the peritoneal permeability by applying a kinetic model for the peritoneal dialysis. Moreover clinical implementations of the novel criterion were validated with using the clinical data. By employing PD NAVI (JMS Co.,Ltd., Hiroshima, Japan), 50 well-being peritoneal dialysis patients performed the peritoneal function test including the peritoneal equilibration test (PET), which measured both urea and creatinine concentrations in the dialysate and drainage volumes. The overall mass transfer area coefficient for urea (MTACu) and that for creatinine (MTACc) were determined from a peritoneal mass transfer model and the clinical data for each patient. An average of MTACu/c which is the ratio of MTACu to MTACc was 1.78 and a standard deviation of that was 0.32. MTACu/c correlated with the drainage volume of PET (r2>0.66). Moreover a decrease of MTACu/c showed the enhancement of the peritoneal permeability (p<0.0001). Furthermore, since MTACu/c implies a peritoneal diffusive selectivity, MTACu/c also correlated with dialysis outcomes such as Kt/V for urea and weekly creatinine clearance normalized to 1.73m2. Then, we could derive some recommendations for MTACu/c by applying the recommendations for the dialysis outcomes such as NKF-DOQI guideline. Thus, MTACu/c can evaluate not only the peritoneal permeability, but also the dialysis outcome. We proposed that MTACu/c is available as the criterion which manages the peritoneal permeability and the therapeutic efficiency of the peritoneal dialysis. [ABSTRACT FROM AUTHOR]

Abstract

This open access book is one in a series of four volumes introducing peatland conservation and restoration in Indonesia. It focuses on local governance, in particular on regional and local perspectives in Riau, the most peat-destructed province of Indonesia. The book fills a vital gap in the existing literature that overlooks social science and humanities perspectives. Written by authors from different disciplines and backgrounds (including scholars and NGO activists), the approaches to the topic are various and unique, including analysis of GPS logs, social media, geospatial assessments, online interviews (conducted due to the Covid-19 pandemic), and more conventional questionnaires and surveys of community members. The chapters cover an interdisciplinary understanding of peatland destruction and broadly offer insights into environmental governance. While presenting combined studies of established fieldwork methodologies and contemporary technology such as drones and geospatial information, the book also explores the potential of long-distance research with rural communities through online facilitation, which was brought about by Covid-19, but that may have long­term implications. Readers will gain a comprehensive understanding of the complexities surrounding peatland conservation and restoration and recognize the significance of locally inclusive approaches that use contemporary but accessible technologies to sustainably govern the globally important resource of peatland. That approach would be useful for other environmentally fragile but important regions and give some ideas to achieve the United Nations’ SDGs for 1)No Poverty, 5)Gender Equality, 13)Climate Action, 15)Life of Land.
