ABSTRACT
Objective@#To investigate the incidence and prognosis of cognitive impairment and to find out the risk factors associated with the outcome for better understanding and preventing cognitive impairment in maintenance hemodialysis (MHD) patients.@*Methods@#The patients who met the criteria as below: MHD patients (≥3 months) in Renji Hospital, Shanghai Jiao Tong University School of Medicine from January 2000 to July 2014, ≥18 years old were enrolled and could carry on the montreal cognitive assessment (MoCA) of voluntary cooperation. According to the score of MoCA, all enrolled patients were divided into two groups: cognitive impairment (MoCA<26) group and non-cognitive impairment (MoCA≥26) group. The follow-up period was 3 years. There were 130 males, and the incidence, demography data, medical history, hemodialysis data, laboratory examination and prognosis of cognitive impairment in hemodialysis patients were prospectively compared and analyzed. Logistic regression analysis was used to investigate the risk factors of cognitive impairment. Kaplan-Meier survival curve and Cox regression model were used for prognostic analysis.@*Results@#A total of 219 MHD patients were enrolled. The incidence of cognitive impairment in MHD patients was 51.6%. There were 130 males, and the ratio of male to female was 1.46∶1. Age was (60.07±12.44) years old and dialysis vintage was (100.79±70.23) months. Compared with non-cognitive impairment group (n=106), patients in cognitive impairment group (n=113) were older, and had higher proportion of education status<12 years, history of diabetes and anuria (all P<0.05); however, the post-dialysis systolic pressure, pre-dialysis diastolic pressure, post-dialysis diastolic pressure, platelet and spKt/V were lower (all P<0.05). Multivariate logistic regression analysis showed that education status<12 years (OR=3.428, 95%CI 1.919-6.125, P<0.001), post-dialysis diastolic pressure<73 mmHg (OR=2.234, 95%CI 1.253-3.984, P=0.006) and spKt/V<1.72(OR=1.982, 95%CI 1.102-3.564, P=0.022) were the independent risk factors for cognitive impairment in MHD patients. The Kaplan-Meier survival curve analysis showed that the survival rate of patients with cognitive impairment was lower than that of non-cognitive impairment group in MHD patients during 3 years follow-up (χ2=3.977, P=0.046). Multivariate Cox regression analysis showed that cognitive impairment was an independent risk factor for death in MHD patients (RR=2.661, 95%CI 0.967-7.321, P=0.058).@*Conclusions@#Cognitive impairment is one of the common complications and an independent risk factor for death in MHD patients. The mortality is high in patients who suffer cognitive impairment. Education status<12 years, post-dialysis diastolic pressure<73 mmHg and spKt/V<1.72 are the independent risk factors for cognitive impairment in MHD patients.

ABSTRACT
Objective To analyze the role of telehealth?based dialysis registration systems in real?time and dynamic reflection of renal anemia in hemodialysis (HD) patients, and discuss the prospect of its application in dialysis registration management. Methods The Red China project was to build up a dialysis registration system based on the WeChat mobile terminal platform. Demographic and baseline laboratory parameters such as age, gender, primary disease, dialysis age, creatinine were recorded in this system. Hemoglobin (Hb) level was monthly recorded. The platform generated Hb statistics report for each HD center monthly, including the detection rate, target rate and the distribution level of Hb, and released it to physicians through the WeChat terminal of mobile phone. After that, physicians could change the treatment of anemia individually on basis of this report. Here the demographic and baseline laboratory parameters, the detection rate, target rate, the average level and the distribution of Hb from June 2015 to October 2017 after the project launched were analyzed. Results From June 2015 to October 2017, 8392 maintenance HD patients from 28 HD centers in Shanghai were enrolled, of whom 5059(60.3％) were male.The average rate age was (60.5 ± 13.7) years old. Baseline average Hb was (108.3±16.0) g/L. Baseline detection rate and target rate were 54.2％and 47.5％, respectively. After 28 months follow?up, the detection rate of Hb increased from 54.2％ to 73.6％ (P<0.001), the target rate of Hb increased from 47.5％ to 56.1％ (P<0.001), and the level of average Hb rose from (108.3±16.0) g/L to (110.7±16.0) g/L. The difference between average Hb in two consecutive months was less than 1.3 g/L. Conclusions The telehealth?based dialysis registration system can timely report the anemia situation of HD patients, which may improve the awareness rate of anemia, the degree of attention and the compliance of anemia monitoring, so as to improve the detection rate and target rate of Hb and reduce the fluctuation of Hb, which helps to maintain the HD patients to correct anemia in a timely, stable and long?term way. The telehealth?based dialysis registration system, as an improved mode of dialysis registration is a promising way for long?term management of renal anemia in dialysis patients.
ABSTRACT
Objective To compare the complications and outcomes of urgent?start peritoneal dialysis (PD) and hemodialysis (HD) in end?stage renal disease (ESRD) patients, and explore the safety and effectiveness of PD which was as an urgent?start dialysis modality in ESRD patients. Methods All patients for urgent?start dialysis, who initiated dialysis without a long?term dialysis access or had the long?term dialysis access under 30 days in Renji Hospital from January 1st 2013 to December 31st 2014, were enrolled. According to the dialysis modalities, patients were divided into PD group and HD group. Participants were followed up until death, transferred to other centers, lost of follow up or January 1st 2016. Dialysis?related complications within 30 days of implantation, complications of reimplantation and the occurrence of bacteremia between two groups were compared, and their survival rates were tested by Kaplan?Meier curves. Results Among 178 patients in this study, there were 96 (53.9%) patients in PD group and 82 (46.1%) patients in HD group. Compared with those of HD group, patients of PD group presented more cardiovascular disease [21(21.9%) vs 8(9.8%), P=0.029], higher serum potassium [(4.5±0.8) mmol/L vs (4.3±0.8) mmol/L, P=0.038], but less heart failure (NYHA Ⅲ?Ⅳ) [26(30.2%) vs 40 (48.8%), P=0.014], lower brain natriuretic peptide (BNP) [328.5 (129.5, 776.8) ng/L vs 503.5(206.0, 1430.0) ng/L, P=0.008], higher hemoglobin [(81.5 ± 17.7) g/L vs (75.3 ± 22.5) g/L, P=0.039], higher serum albumin (33.5±5.7) g/L vs (31.3±6.7) g/L, P=0.022] and higher serum pre?albumin (304.5±78.0) mg/L vs (257.0 ± 86.1) mg/L, P<0.001]. PD group presented less dialysis?related complications [5 (5.2%) vs 20(24.4%), P<0.001], less dialysis?related complications requiring reimplantation [1(1.0%) vs 20(24.4%), P<0.001] and less bacteraemia [3(3.1%) vs 11(13.4%), P=0.011]. The 3?, 6?and 12?month patient survival rates of PD and HD group were 97.9% vs 98.4%, 97.9% vs 98.4%, and 92.1%vs 93.0% respectively, and no significant difference was found (Log ? rank=0.004, P=0.947). Conclusions Patients with urgent?start PD have less complications within 30 days of implantation and occurrence of bacteremia than patients with urgent?start HD, and the same survival rates. PD may be a feasible and safe urgent?start dialysis modality for ESRD patients.
