A diagnostic-therapeutic pathway for patients with kidney stone disease was first published on this Journal in 2010. The present contribution aims at amending and updating the article published exactly ten years ago, to serve as an easy-to-use reference and to guide good clinical practice in this field.Questo documento è stato tradotto dall'inglese a nome dell'ERBP (European Renal Best Practice), un organo ufficiale dell'ERA-EDTA (European Renal Association - European Dialysis and Transplant Association), e si basa su una pubblicazione ufficiale edita su Nephrology, Dialysis and Transplantation (NDT).

MF-438 https//doi.org/10.1093/ndt/gfz072.Background Given the public health challenge represented by chronic kidney disease, the Italian Society of Nephrology (SIN) promoted a census of the renal and dialysis units to analyze structural and human resources, organizational aspects, activities and workload, referring to the year 2018. Methods An on-line questionnaire including 60 questions, exploring structural and human resources, organizational aspects, activities and epidemiological data referred to 2018, was sent to the heads of all identified Italian renal or dialysis unit. Results 567 renal units were identified, 3.3 public and full renal unit pmp. The nephrology beds are about 37.6 pmp. The nurses were 8,130 in HD wards, 1,827 in the nephrology wards, only 432 for outpatient clinics. Conclusions Data from this census may be used for benchmarking and comparison between centers, regions and groups of regions. These data offer a snapshot of the clinical management of renal disease in Italy.Background Given the public health challenge represented by chronic kidney disease, the Italian Society of Nephrology (SIN) promoted a census of the renal and dialysis units to analyze structural and human resources, organizational aspects, activities and workload, referring to the year 2018. Methods An on-line questionnaire including 60 questions, exploring structural and human resources, organizational aspects, activities and epidemiological data referred to 2018, was sent to the heads of all identified Italian renal or dialysis unit. Results Renal and dialysis activity was performed by over 2,718 physicians (41 pmp). The management of the acute renal failure was one of the most relevant activities in the public renal units (3,000 pmp patients in ICU and 183.000 dialysis sessions). Italian Nephrologists performed about 6000 AV fistulas out of a total of 9300. In the survey there are a lot of data regarding organization, workforce and workload of the renal unit in Italy. Conclusions Data from this census may be used for benchmarking and comparison between centers, regions and groups of regions. These data offer a snapshot of the clinical management of renal disease in Italy.The current experiments investigate how infants use goal-directed action to reason about intentionally sampled outcomes in a probabilistic inference paradigm. Older infants and young children are flexible in their expectations of sampling They expect random samples to reflect population statistics and non-random samples to reflect an agent's preferences or goals (Kushnir, Xu, & Wellman, 2010; Xu & Denison, 2009). However, more recent work shows that probabilistic inference comes online at approximately 6 months (Denison, Reed, & Xu, 2013; Kayhan, Gredebäck, & Lindskog, 2017; Ma & Xu, 2011; Wellman, Kushnir, Xu, & Brink, 2016), and thus, these sampling assumptions can be investigated at the age probabilistic reasoning first emerges. Results indicate that 6-month-old infants expect a human agent to sample in accord with their goal and do not expect the same of an unintentional agent-a mechanical claw. By 9.5 months, infants expect the mechanical claw to sample in accord with random sampling. These results suggest that infants use goals to make inferences about intentional sampling, under appropriate conditions at 6 months, and they have expectations of the kinds of samples a mechanical device should obtain by 9.5 months.Uneven distribution of pores, lack of connection between holes, low reproducibility, insufficient mechanical strength, and incomplete volatility of organic solvents are some problems associated with traditional tissue engineering methods for bone defect repair. These characteristics reduce the quality and stability of products. This study uses 3D printing (3DP) to fabricate a biocompatible poly(lactic) acid-based scaffold for repairing bone tissue. Hence, three different types of scaffolds are assessed a freeze-dried polylactic acid (PLA) scaffold constructed using the traditional freeze-extraction method; a 3D-PLA scaffold produced through the 3DP technique; and a 3D-PLA-bone morphogenetic protein-2 (BMP-2) scaffold that is prepared using 3DP technology, with the addition of BMP-2. To enhance biological activity, polydopamine (pDA) is used to graft BMP-2 on the surface of the 3D-PLA-BMP-2 scaffold. Then, the scaffolds are implanted into the bilateral femoral condyles of rabbits, and their ability to repair the bone tissue defects is tested. The results of the experiments reveal that the 3DP scaffolds are more biocompatible than the ones produced through the traditional manufacturing methods because they enhance cell adhesion and differentiation after pDA modification and BMP-2 fixation. In the future, the 3DP products may be applied for the repair of larger bone defects in the clinical setting.During oxidative depolymerization of lignin in aqueous alkaline medium using molecular oxygen as oxidant, the highly functionalized primary phenolic monomers are not stable products, owing to various not fully identified secondary reaction mechanisms. However, better understanding of the mechanisms responsible for the instability of the main part of the products of interest derived from lignin is of much interest. Evaluation of their individual reactivities under oxidative conditions should significantly help to find a better way to valorize the lignin polymer and to maximize the yields of target value-added products. Consequently, the main objective of this study is to assess the individual stabilities of some selected lignin-based phenolic compounds, such as vanillin, vanillic acid, and acetovanillone, together with some other pure chemical compounds such as phenol and anisole to give an insight into the mechanisms responsible for the simultaneous formation and repolymerization of those products and the influence of the oxidation conditions.
