RESUMO
Background: Due to its chronic and progressive nature, chronic kidney disease (CKD) affects patients in many spheres including their perception of quality of life (QOL). Breathing training techniques have shown positive effects on health and QOL for different conditions. Objective: The aim of this study was to perform a scoping review to examine the characteristics related to the application of breathing training on patients with CKD, and to identify the relevant outcomes and target group for the application of breathing training. Methods: This scoping review was performed in accordance with PRISMA-SRc guidelines. We systematically searched three electronic databases for articles published before March 2022. The studies included patients with chronic kidney disease that received breathing training programs. The breathing training programs were compared to usual care or no treatment. Results: A total of four studies were included in this scoping review. The four studies had heterogeneous disease stages and breathing training programs. All the studies included reported positive effects of breathing training programs on QOL of CKD patients. Conclusion: The breathing training programs were able to improve the quality of life of patients with CKD undergoing hemodialysis treatment.
RESUMO
INTRODUCTION: Despite the high incidence of posttransplant diabetes mellitus (PTDM) among high-risk recipients, no studies have investigated its prevention by immunosuppression optimization. METHODS: We conducted an open-label, multicenter, randomized trial testing whether a tacrolimus-based immunosuppression and rapid steroid withdrawal (SW) within 1 week (Tac-SW) or cyclosporine A (CsA) with steroid minimization (SM) (CsA-SM), decreased the incidence of PTDM compared with tacrolimus with SM (Tac-SM). All arms received basiliximab and mycophenolate mofetil. High risk was defined by age >60 or >45 years plus metabolic criteria based on body mass index, triglycerides, and high-density lipoprotein-cholesterol levels. The primary endpoint was the incidence of PTDM after 12 months. RESULTS: The study comprised 128 de novo renal transplant recipients without pretransplant diabetes (Tac-SW: 44, Tac-SM: 42, CsA-SM: 42). The 1-year incidence of PTDM in each arm was 37.8% for Tac-SW, 25.7% for Tac-SM, and 9.7% for CsA-SM (relative risk [RR] Tac-SW vs. CsA-SM 3.9 [1.2-12.4; P = 0.01]; RR Tac-SM vs. CsA-SM 2.7 [0.8-8.9; P = 0.1]). Antidiabetic therapy was required less commonly in the CsA-SM arm (P = 0.06); however, acute rejection rate was higher in CsA-SM arm (Tac-SW 11.4%, Tac-SM 4.8%, and CsA-SM 21.4% of patients; cumulative incidence P = 0.04). Graft and patient survival, and graft function were similar among arms. CONCLUSION: In high-risk patients, tacrolimus-based immunosuppression with SM provides the best balance between PTDM and acute rejection incidence.
RESUMO
BACKGROUND AND OBJECTIVE: The Kidney Donor Profile Index (KDPI), together with other donor and recipient variables, can optimise the organ allocation process. This study aims to check the feasibility of the KDPI for a Spanish population and its predictive ability of graft and patient survival. MATERIALS AND METHODS: Data from 2,734 kidney transplants carried out in Andalusia between January 2006 and December 2015 were studied. Cases were grouped by recipient age, categorised by KDPI quartile and both graft and patient survival were compared among groups. RESULTS: The KDPI accurately discriminated optimal organs from suboptimal or marginal ones. For adult recipients (aged: 18-59years) it presents a hazard ratio of 1.013 (P<.001) for death-censored graft survival and of 1.013 (P=.007) for patient survival. For elderly recipients (aged: 60+years), KDPI presented a hazard ratio of 1.016 (P=.001) for death-censored graft survival and of 1.011 (P=.007) for patient survival. A multivariate analysis identified the KDPI, donor age, donation after circulatory death, recipient age and gender as predictive factors of graft survival. CONCLUSIONS: The results obtained show that the KDPI makes it possible to relate the donor's characteristics with the greater or lesser survival of the graft and the patient in the Spanish population. However, due to certain limitations, a new index for Spain based on Spanish or European data should be created. In this study, some predictive factors of graft survival are identified that may serve as a first step in this path.
