Background: In peritoneal dialysis, technique failure is an important metric to be considered. This study was performed in order to identify the relationship between trajectories of serum albumin levels and peritoneal dialysis technique failure on end-stage renal disease patients according to diabetic status. Furthermore, this study was performed to reveal predictors of serum albumin and technique failure simultaneously. Methods: This retrospective cohort study included 300 (189 non-diabetic and 111 diabetic) end-stage renal disease patients on continuous ambulatory peritoneal dialysis treated in Al-Zahra Hospital, Isfahan, Iran, from May 2005 to March 2015. Bayesian joint modeling was carried out in order to determine the relationship between trajectories of serum albumin levels and peritoneal dialysis technique failure in the patients according to diabetic status. Death from all causes was considered as a competing risk. Results: Using joint modeling approach, a relationship between trajectories of serum albumin with hazard of transfer to hemodialysis was estimated as -0.720 (95% confidence interval [CI], -0.971 to -0.472) for diabetic and -0.784 (95% CI, -0.963 to -0.587) for non-diabetic patients. From our findings it was showed that predictors of low serum albumin over time were time on peritoneal dialysis for diabetic patients and increase in age and time on peritoneal dialysis, history of previous hemodialysis, and lower body mass index in non-diabetic patients. Conclusion: The results of current study showed that controlling serum albumin over time in non-diabetic and diabetic patients undergoing continuous ambulatory peritoneal dialysis treatment can decrease risk of adverse outcomes during the peritoneal dialysis period.

The shortage of clean water sources and increase of demand for fresh water have become as major globalchallenges not only in industries but also inhuman life. Meanwhile, membrane technology has beenextensively noticed due to high separation efficiency, energy-saving and environmentally-friendly characteristic. So, development of new membrane is a vital step in advancing of membrane application inwater-treatment. This paper presents a comprehensive review on development of high-performancenanofiltration membrane based on nanotechnology for wastewater treatment. Application of new nanomaterialshas enabled fabrication of NF-membranes with improved separation properties for pollutantsremoval from water. Recognizing that conventional membranes are not necessarily suitable for industrialapplications and/or process intensifications many attempts were made recently to use of nanomaterialsinto NF-membranes, aiming to overcome trade-off relationship between flux/selectivity and to improvetheir stability. So, development of new structured nanomaterial with desirable properties is one of mostcrucial research topics for membrane researchers. Accordingly, an overview on different methods todesign of advanced nanomaterial presented that allow us to overcome their inherent problems in membranesfabrication such as agglomeration, defects formation, insufficient pores’ tuning, poor active sitesand anti-fouling properties; however, selection of appropriate nanomaterials is a challenge of utmost difficulty. Various types of nanomaterials such as zeolites, carbon based, framework (MOF/ZIF/COF), nanobiopolymersand special nanoparticles such as SFNPs, SFNCs, POSS, ZCPs, and nickel hydroxide nanosheetare presented and their roles in NF-transport are discussed as well as strategies for surface modificationof nanoparticles to promoting their surface charges density. Moreover, fabrication methods of nanoenhanced NF-membranes including layer by layer assembly, hollow fiber spinning, electrospinning ofnanofibers, construction of thin-film nanocomposite besides blending, co-polymerization; cross-linkingand grafting techniques are discussed. A proper view for selection of appropriate nanoparticles in membranefabrication is offered while considering types of pollutants to be removed.
