Most patients with end-stage renal disease choose maintenance hemodialysis to prolong survival. The clinical application of exercise therapy has a definite effect on maintenance hemodialysis patients, and can effectively improve their quality of life and promote rehabilitation. Individualized exercise therapy under the guidance of medical professionals has positive effects on patients’ physical and mental rehabilitation. This paper mainly summarizes the status of exercise, factors affecting exercise, exercise therapy, exercise and rehabilitation of maintenance hemodialysis patients, and reviews the impact of exercise therapy on the physical and mental health of maintenance hemodialysis patients, in order to provide some references for clinical intervention and prognosis studies.
Objective To understand the incidence of frailty in maintenance hemodialysis (MHD) patients, and to explore the correlation and influencing factors of frailty in MHD patients, so as to provide some basis for the intervention of frailty in MHD patients. Methods Patients who underwent MHD in the Department of Nephrology of West China Hospital of Sichuan University from January to March 2021 were selected. Frail scale and Pittsburgh Sleep Quality Index (PSQI) were used for evaluation, and the influencing factors of frail in patients with MHD and its correlation with frail were analyzed. Results A total of 141 patients with MHD were included, including 57 cases without frailty (40.43%), 71 cases in early frailty (50.35%), and 13 cases in frailty (9.22%). 54 cases (38.30%) had very good sleep quality, 56 cases (39.72%) had good sleep quality, 24 cases (17.02%) had average sleep quality, and 7 cases (4.96%) had very poor sleep quality. The frailty of MHD patients was positively correlated with age (rs=0.265, P=0.002), PSQI (rs=0.235, P=0.005) and magnesium (rs=0.280, P=0.001). Logistic regression analysis showed that the influencing factors of MHD patients’ frailty were gender [odds ratio (OR) =4.321, 95%confidence interval (CI) (1.525, 12.243), P=0.006], PSQI [OR=1.110, 95%CI (1.009, 1.222), P=0.032], magnesium [OR=122.072, 95%CI (4.752, 3 135.528), P=0.004], hypertension [OR=0.112, 95%CI (0.023, 0.545), P=0.007] and other diseases [OR=0.102, 95%CI (0.019, 0.552), P=0.008]. Conclusions The incidence of frailty in MHD patients is high. Gender, PSQI, magnesium, hypertension and other diseases are the influencing factors of frailty in MHD patients, and there is a correlation between frailty and sleep. It is suggested that renal medical staff should pay more attention to the assessment of MHD frailty and sleep, and carry out multi-disciplinary personalized intervention to improve the quality of life of MHD patients.
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.
ObjectiveTo understand the maintenance hemodialysis (MHD) patients’ intention to exercise rehabilitation and discuss the influencing factors.MethodsFrom January to March 2019, 141 MHD patients’ intention to exercise rehabilitation was investigated by cross-sectional survey, and the influencing factors of MHD patients’ intention to exercise rehabilitation were analyzed by multiple linear stepwise regression.ResultsA total of 141 questionnaires were issued and 139 valid ones were recovered. The mean score of exercise rehabilitation intention of MHD patients was 39.99±9.29, which was in the middle and high level. Age [unstandardized partial regression coefficient (b)=?5.277, 95% confidence interval (CI) (?8.640, ?1.915), P=0.002], educational level [b=2.412, 95%CI (1.161, 3.663), P<0.001], and 6-minute walking distance [b=3.526, 95%CI (0.032, 7.021), P=0.048] were the influencing factors of exercise rehabilitation intention of MHD patients.ConclusionMHD patients have high intension to exercise rehabilitation, and special attention should be paid to elderly patients and patients with low education level in clinical work to improve their intension to exercise rehabilitation.
ObjectiveTo investigate the efficacy of Quality Control Circles (QCC) in reducing the emergency application times of maintenance hemodialysis. MethodsIn December, 2012, the quality circle was formed by eight nurses and a physician, through brainstorming. The group finally selected "Reducing emergency maintenance dialysis times" as the theme. With the help of questionnaire, interview, and comparative study, we analyzed the emergency situation of maintenance hemodialysis patients, and regulate and implement related policies. ResultsBy QCC practices, the times of hemodialysis declined from 11.7 to 5.3 cases per month, which exceeded our expectations largely. As to the circle members, their problem-solving skills, responsibility, communication skills, self-confidence, motivation and QCC techniques were also improved. ConclusionQCC can not only reduce the times of maintenance dialysis, but also improve the team cohesion, harmony and quality management capabilities.
Objective To investigate the correlation between grip strength and subjective cognitive decline (SCD) in maintenance hemodialysis (MHD) patients of different genders. Methods Patients who underwent outpatient MHD in the Wenjiang Hemodialysis Unit, Department of Nephrology, West China Hospital, Sichuan University between March and June 2024 were selected as the research subjects. Multiple linear regression analysis was used to explore the relationship between grip strength and SCD in MHD patients of different genders. Results A total of 171 patients were investigated, with 76 in the non-SCD group and 95 in the SCD group. The results of multiple linear regression analysis showed that educational level (P=0.039), nutritional status (P=0.026), and grip strength (P=0.042) were the influencing factors of SCD in male MHD patients. Work status (P=0.001) and nutritional status (P=0.011) were the influencing factors of SCD in female MHD patients. Conclusions Educational level, nutritional status, and grip strength are influencing factors of SCD in male MHD patients. Work status and nutritional status are influencing factors of SCD in female MHD patients. Grip strength may serve as an indicator for evaluating SCD in male MHD patients.
ObjectiveTo investigate the effect of 24-week intradialytic progressive resistance exercise on hemoglobin and iron metabolism in maintenance hemodialysis (MHD) patients.MethodsFrom April to May 2019, 62 MHD patients were enrolled and randomly assigned into exercise group (n=31) and control group (n=31). Both groups of patients received regular routine hemodialysis, on that basis, patients in the exercise group completed intradialytic resistance exercise three times per week for 24 weeks. Each exercise included 8-10 muscle groups (grasping the grip ring with both hands, flexion and extension of the elbows and shoulders on the non-vascular side and lower limbs with sandbag), 3 sets of 15 repetitions with a rest of 1-2 min between 2 sets. Exercise began with a low load, the sandbag weight was gradually increased, and the Borg score was aimed to be 11-13 points after exercise. Hemoglobin, serum ferritin, transferrin saturation, serum creatinine, high-sensitivity C-reactive protein, urea clearance index, recombinant human erythropoietin (rHuEPO) dosage at baseline and after 24 weeks, as well as the cumulative iron supplement dose and hemoglobin variation of the two groups during the study period were evaluated.ResultsThere were 20 patients in the exercise group and 30 ones in the control group who completed the study. After 24 weeks of progressive resistance exercise, the medium (lower quartile, upper quartile) of the amount of rHuEPO in the exercise group decreased from 6 000 (6 000, 9 000) U/week to 6 000 (4 500, 7 125) U/week (Z=?2.599, P=0.009), while that in the control group had no statistically significant difference (Z=?1.340, P=0.180); there was no statistically difference in hemoglobin, hemoglobin coefficient of variation, serum ferritin, transferrin saturation, or 24-week cumulative iron supplementation between the two groups.ConclusionIntradialytic progressive resistance exercise can reduce the amount of rHuEPO in MHD patients, which is benefitial to optimizing the management of hemoglobin.
ObjectiveTo investigate the relationship among bone density, osteoprotegerin (OPG) and vascular calcification (VC) in maintenance hemodialysis (MHD) patients. MethodsOne hundred MHD patients were collected from our department between May 2010 and December 2012. The VC was detected by plain radiographs. Bone mineral density was measured with dual-energy X-ray absorptionmeter. The level of serum OPG was measured by enzymelinked immunosorbent assay. Other clinically related indicators were also detected. The related parameters were examined statistically. ResultsThe incidence of VC in MHD patients was 74% (74/100), and the OPG level significantly increased with the degree of vascular calcification (P<0.05). The proportion of patients with normal bone volume was 40%, and with abnormal bone volume was 60%. Compared with patients with normal bone volume, the patients with abnormal bone volume had higher serum OPG level (P<0.05). The patients with no VC had a lower incidence of abnormal bone volume than patients with VC (P<0.05). Multiple linear regression analysis revealed that vascular calcification score, OPG level and age were independent factors for bone mineral density. Dialysis time, OPG level, serum albumin level and bone mineral density were independent factors for vascular calcification score. ConclusionThe MHD patients with vascular calcification are often associated with osteoporosis at the same time. OPG plays an important role in the relationship between vascular calcification and osteoporosis.
ObjectiveTo discuss and analyze the sense of dignity and its influencing factors of maintenance hemodialysis (MHD) patients.MethodsPatients with MHD in hemodialysis center of West China Hospital of Sichuan University were selected from November 2019 to January 2020. Patients were selected by convenience sampling. The patients were investigated with Patient Dignity Inventory (PDI), Connor-Davidson Resilience Scale (CD-RISC) and Hospital Anxiety and Depression Scale.ResultsA total of 150 patients were included. The average scores of CD-RISC, anxiety, depression and PDI were 61.20±14.54, 4.97±1.38, 5.90±2.42 and 41.32±16.24, respectively. Among them, 121 cases (80.67%) had mild dignity impairment, 22 cases (14.67%) had moderate dignity impairment, 6 cases (4.00%) had severe dignity impairment, and 1 case (0.67%) had very serious dignity impairment. The results of multiple linear stepwise regression showed that depression, economic burden, social support, and vascular access were all positive predictors of esteem scores (P<0.001).ConclusionsClinical nurses can aim at the main factors affecting the sense of dignity of MHD patients. And individualized nursing plan and intervention measures can be formulated to improve the sense of dignity of patients and improve the quality of life of maintenance hemodialysis patients.
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.
