Blood pressure variability (BPV) refers to the fluctuations of blood pressure in a certain period of time. In recent years, BPV is becoming a predictive marker for cardiovascular events. Given the hemodynamic and internal environmental change brought by hemodialysis as well as the complex complications, hemodialysis patients always have complex BPV. Nowadays there is no consensus on an optimal standard to evaluate BPV in hemodialysis population. Metrics usually used are as follows: blood pressure change during a certain period of time, standard deviation, coefficient of variation, variation independent of mean, average real variability, weighted mean of daytime and night-time standard deviation, residual derived from generalized linear models, and residual standard deviation. Impact factors of BPV in hemodialysis patients include age, ultrafitration volume, hemodialysis frequency and time length, peripheral vascular disease, serum calcium, antihypertensive drugs and so on. Recent studies showed significant associations between both long-term and short-term BPV with prognosis of hemodialysis patients. This review focuses on the evaluation methods, the influencing factors and the impact on prognosis of BPV.
Objective To explore the current situation and influencing factors of self-regulatory fatigue in maintenance hemodialysis (MHD) patients, so as to provide good dialysis treatment for MHD patients, reduce their level of self-regulated fatigue and improve their quality of life. Methods The convenient sampling method was used to select the MHD patients in the Wenjiang Hemodialysis Center of West China Hospital of Sichuan University between April 12 and April 30, 2022. The patients were investigated by self-made basic information scale and self-regulatory fatigue scale. Results A total of 131 patients were included. The average score of self-regulatory fatigue was 53.47±6.45, cognitive dimension was 20.21±2.39, emotional dimension was 20.85±2.85, behavioral dimension was 12.40±3.63. The results of multiple linear stepwise regression analysis showed that age, duration of dialysis and educational background could inversely predict the score of self-regulatory fatigue (P<0.05). Conclusions MHD patients have a high level of self-regulatory fatigue. Clinical nurses can make individual dialysis programs according to the actual situation of MHD patients, improve their self-regulated level and physical and mental health, and improve the quality of life of MHD patients.
Objective To explore the current status of electronic health (eHealth) literacy and online health information seeking behavior of maintenance hemodialysis (MHD) patients, and to explore the relationship between them. Methods MHD patients in the Hemodialysis Center of West China Hospital of Sichuan University between January and April 2022 were selected by convenient sampling method. The patients were investigated with general condition questionnaire, eHealth Literacy Scale and internet health information retrieval behavior questionnaire. According to the score of eHealth literacy, patients were divided into high eHealth literacy group and low eHealth literacy group, to compare the differences between the two groups, and analyze the factors that affected the internet health information retrieval behavior. Results A total of 194 MHD patients were included. Among them, 112 were male and 82 were female. The average score of eHealth literacy was 24.84±9.24. There were 136 cases in low eHealth literacy group, and the average score of eHealth literacy was 20.76±7.91. There were 58 cases in high eHealth literacy group, and the average score of eHealth literacy was 34.36±3.01. Multivariate analysis showed that eHealth literacy and education level were the influencing factors of health information search behavior (P<0.05). Conclusions The overall eHealth literacy of MHD patients is low, and the online health information search means is single and behaviorally inconsistent. It is necessary to improve the eHealth literacy of hemodialysis patients, and at the same time, provide various health information publicity and education for patients with different levels of eHealth literacy, which will help them better carry out disease management.
Objective To explore the current status of nutritional literacy in maintenance hemodialysis (MHD) patients and analyze its influencing factors. Methods MHD patients in Wenjiang Hemodialysis Center of West China Hospital, Sichuan University between January and April 2022 were selected by convenient sampling method. A questionnaire survey was conducted using the Nutrition Literacy Evaluation Scale for end-stage renal disease dialysis patients, and the current status and influencing factors of nutritional literacy in MHD patients were analyzed. Results A total of 214 patients were included, with an average nutritional literacy score of 19.14±5.78 for MHD patients. Among them, there were 60 cases (28.04%) of highly likely low nutritional literacy, 124 cases (57.94%) of moderate nutritional literacy, and 30 cases (14.02%) of highly likely high nutritional literacy. The correlation test results showed that hemoglobin, albumin, cholesterol, triglyceride, calcium, phosphorus, potassium, creatinine, estimated glomerular filtration rate, and nutritional literacy scores were not correlated. The results of multiple linear stepwise regression analysis showed that education level [non-standardized partial regression coefficient (b)=1.821, 95% confidence interval (CI) (1.143, 2.498), P<0.001], age [b=−2.460, 95%CI (−4.247, −0.672), P=0.007], hypertensive kidney damage [b=2.233, 95%CI (0.428, 4.039), P=0.016] were all factors affecting the nutritional literacy of MHD patients. Conclusions In clinical work, more attention should be paid to MHD patients with low educational level, older age, and more primary diseases. And targeted interventions should be adopted to improve the level of nutritional literacy in order to improve the quality of life of MHD patients.
Objective To study the influence of calcium acetate tablets combined with compound alpha-keto acid on calcium and phosphorus metabolism in maintenance hemodialysis (MHD) patients. Methods A total of 112 MHD patients with hyperphosphatemia treated between May 2014 and May 2015 were included in this study. Based on random number table method, they were divided into calcium acetate group (n=37), compound alpha-keto acid group (n=36) and combined drug use group (n=39). All the patients were given a low protein diet. Twelve weeks after treatment, we compared the calcium and phosphorus metabolic indexes, nutrition indicator levels and adverse reactions within and across the three groups. Results Before treatment, there was no significant difference among the three groups in terms of serum calcium, phosphorus, calcium-phosphorus product, and parathyroid hormone (PTH) level (P>0.05). After treatment, the combined drug use group had significantly lower levels of serum phosphorus, calcium-phosphorus product and PTH than the other two groups (P<0.05). Before treatment, the levels of creatinine, serum total protein and albumin were not significantly different among the three groups (P>0.05). After treatment, the serum total protein and albumin level in the combined drug use group were significantly higher than those in the other two groups (P<0.01). Three was no significant difference among the three groups in terms of adverse reactions (P>0.05). Conclusions For MHD patients with hyperphosphatemia, the combined use of calcium acetate tablets and compound alpha-keto acid is better than the use of single drugs, which can effectively improve patients’ symptoms and reduce the level of serum phosphorus with high security. It is worthy of clinical recommendation.
ObjectiveTo preliminarily explore the effect of Osteoporosis Self-assessment Tool for Asians (OSTA) and Fracture Risk Assessment Tool (FRAX) on predicting osteoporosis and osteoporosis fracture in postmenopausal patients with maintenance hemodialysis (MHD).MethodsThirty-six postmenopausal patients undergoing MHD from August 2017 to October 2018 in Hemodialysis Center of Nephrology Department, West China Hospital of Sichuan University were selected. Relevant data such as age, height, and weight were collected. OSTA index and the 10-year probability of major osteoporotic fractures and 10-year probability of hip fractures of FRAX score were calculated. Bone mineral densities (BMD) of the hip and lumbar spine were measured by dual energy X-ray absorptiometry (DXA) at the same time. The value of OSTA index and FRAX scale in evaluating the risk of osteoporosis predicated on T value ≤−2.5 determined by DXA BMD and fracture in postmenopausal patients with MHD were analyzed.ResultsThe DXA BMD of the 36 patients showed that 50.0% (18/36) had a T value≤−2.5, and 30.6% (11/36) had a fracture history. BMD in postmenopausal patients with MHD was negatively correlated with FRAX score (model without BMD values), and positively correlated with OSTA index. The sensitivity and specificity of OSTA in the prediction of osteoporosis were 94.4% and 61.1%, respectively; and the sensitivity and specificity of FRAX (the model without BMD values) in the prediction of osteoporosis were 88.9% and 50.0%, respectively. The FRAX score with or without BMD had the same clinical value in predicting osteoporosis.ConclusionsPostmenopausal MHD patients have a higher risk of osteoporosis and fracture. Both OSTA index and FRAX scale can predict osteoporosis risk among postmenopausal MHD patients, and the FRAX scale with or without BMD has the same clinical value in predicting osteoporosis risk. In clinical work, for primary hospitals and dialysis centers lacking DXA, preliminary screening of osteoporosis in MHD patients can be performed with OSTA and FRAX scales.
The incidence of sarcopenia and frailty in maintenance hemodialysis patients are high, and there are often comorbidities, which easily lead to more complications, thus increasing the hospitalization rate and reducing the quality of life of patients. This article reviews the definition, physiological mechanism, incidence and diagnosis, relationship and treatment strategies of sarcopenia and frailty in maintenance hemodialysis patients, in order to better prevent and intervene the occurrence of sarcopenia and frailty and provide a reference for prevention and treatment.
Patients undergoing maintenance hemodialysis are characterized with lower cardiorespiratory capacity and muscle atrophy, thus easily leading to a sedentary lifestyle. These patients are usually associated with lower quality of life and worse prognosis. Evidence indicates appropriate exercise rehabilitation plan could help maintenance hemodialysis patients achieve better health outcomes. However, there is still a lack of evidence data to precisely recommend exercise type, intensity, frequency and timing specially designed for maintenance hemodialysis patients. This article aims to summarize the existing expert consensus on exercise rehabilitation for maintenance hemodialysis patients, important considerations in the implementation process, factors that affect exercise rehabilitation, with a view to encouraging maintenance hemodialysis patients to participate in the development of appropriate exercise rehabilitation plan and maximize health benefits.
ObjectiveTo investigate the level and influencing factors of self-management behaviors among maintenance hemodialysis patients.MethodsPatients undergoing maintenance hemodialysis were recruited from 4 tertiary hospitals in Chengdu from October 2016 to October 2017. Convenient sampling method was used to select patients. The instruments used in the study included General Information Questionnaire, Hemodialysis Self-management Instrument, Hemodialysis-related Knowledge Questionnaire, Herth Hope Index, Multidimensional Health Locus of Control Scale, and Chronic Illness Resources Survey.ResultsA total of 360 patients were investigated, and 343 patients were finally included. The mean score of self-management behavior was 54.87±9.65. The results of multiple linear stepwise regression showed that gender, age, ethnic, monthly family income, chronic illness resources, knowledge and internal health locus of control were the significant influencing factors of self-management behaviors (P<0.05).ConclusionThe self-management behavior among patients undergoing maintenance hemodialysis can be promoted by improving the level of knowledge and internal health locus of control, and making effective use of chronic illness resources.
