Objective To investigate the awareness and clinical needs of wearable artificial kidney among maintenance hemodialysis (MHD) patients, and to analyze the related influencing factors. Methods MHD patients were recruited from 2 tertiary hospitals in Sichuan province between April and June 2021. The convenient sampling method was used to select patients. The factors influencing the awareness and demand of MHD patients for wearable artificial kidney were analyzed. Results A total of 119 MHD patients were included. The awareness of wearable artificial kidney among the patients was mainly “never heard” (61 cases) and “heard” (58 cases). Most MHD patients (60 cases) were willing to use and participate in clinical trials in the future. The results of logistic regression indicated that the cost on household economy and treatment effect on life quality were the influencing factors for MHD patients’ awareness of wearable artificial kidney (P<0.05). The average duration of single dialysis and the impact of treatment on working or studying were the influencing factors for MHD patients’ needs of wearable artificial kidney (P<0.05). Conclusions The awareness of wearable artificial kidney is low among MHD patients. However, most MHD patients showed great interest in the wearable artificial kidney after preliminary understanding, suggesting that the future clinical application of wearable artificial kidney has great demand.
ObjectiveTo evaluate the efficacy of the continuous renal replacement therapy (CRRT) for acute kidney injury (AKI) after the surgery of type A aortic dissection.
MethodsWe retrospectively analyzed 58 hemodialysis patients with AKI after type A aortic dissection surgery in our hospital between January 2003 and January 2014.The 58 patients were divided into two groups including a bedside intermittent hemodialysis (IHD) group and a CRRT group based on the methods of hemodialysis. There were 38 patients with 29 males and 9 females at average age of 49.8± 13.7 years in the CRRT group. There were 20 patients in the IHD group with 14 males and 6 females at average age of 52.6± 11.0 years.
ResultsCompared with IHD, CRRT had significantly greater effect on reducing the simplified acute physiology scoring system (SAPS)Ⅱscore (Ftime=60.964, P=0.000; Ftime * group=3.178, P=0.041). However, there was no significant difference in reducing the acute tubular necrosis individual illness severity index (ATN-ISI) score between the two groups (Ftime=13.803, P=0.000; Ftime * group=0.222, P=0.951). Lower incidences of dialysis-related complications including hypotension (P=0.027) and acute congestive heart failure (P=0.011) were found in the CRRT group. There was no statistical difference in operation time (P=0.367) between the two groups. While statistical differences in duration of hospitalization in intensive care unit (P=0.006), in hospital time (P=0.047), frequency of dialysis (P=0.001), and dialysis time (P=0.039) were found between the two groups. However there were no significant differences in mortality during hospital (P=0.544)and incidences of recovery (P=0.056) between the two groups.
ConclusionCompared with IHD, CRRT had significantly positive effect on patients who suffered from AKI after type A aortic dissection surgery, which can help reduce incidences of dialysis-related complications, duration and cost of hospitalization in ICU.
Objective To explore the potential categories and influencing factors of chronic comorbidity treatment burden in maintenance hemodialysis (MHD) patients. Methods Convenience sampling method was used to select MHD patients between April and May 2023 at Northern Jiangsu People’s Hospital and Jiangdu People’s Hospital as the research subjects. The general information questionnaire, Chronic Disease Comorbidity Treatment Burden Scale, and Health Literacy Scale for Chronic Disease Patients were used for the questionnaire survey. The latent class analysis was used to explore the classification of chronic comorbidity treatment burden in MHD patients, and the multi-class logistic regression analysis was used to explore the influencing factors of comorbidity treatment burden. Results A total of 450 survey questionnaires were distributed, and 406 valid questionnaires were collected, with an effective response rate of 90.22%. According to the latent class analysis results, the comorbidity treatment burden of MHD patients was divided into three potential categories. Among them, there were 26 cases in the low-burden group, 194 cases in the medium-burden group, and 186 cases in the high-burden group. The results of the ordered multi-class logistic regression analysis showed that patient age, educational level, dialysis age, number of comorbidities, and level of economic support were potential factors affecting the comorbidity treatment burden in MHD patients (P<0.05). Conclusions The comorbidity treatment burden of MHD patients can be divided into three potential categories. The age, educational level, dialysis age, number of comorbidities, and level of economic support of patients are potential factors affecting the comorbidity treatment burden in MHD patients.
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.
Objective To explore the vascular access infection (VAI) incidence of hemodialysis patients during the the maximum spread of the COVID-19 epidemic (epidemic period) compared with the corresponding period with no local cases of COVID-19 (control period). Methods A single-center, retrospective study was carried out. Adult patients who underwent hemodialysis at the Department of Blood Purification Center, the Affiliated Hospital of Xuzhou Medical University during the epidemic period between December 7, 2022 and February 23, 2023 and the control period between December 7, 2020 and February 23, 2021 were selected. The incidence of local access site infection (LASI) and access related bloodstream infection (ARBSI) in included patients were observed and compared. ResultsA total of 1 401 patients were included. Among them, there were 737 cases during the epidemic period and 664 cases during the control period. There was no statistically significant difference in the age, gender, and duration of catheterization among patients of different periods and pathway types (P>0.05). There was no statistically significant difference in the occurrence of LASI between the epidemic period and the control period (χ2=1.800, P=1.180). There was a statistically significant difference in the occurrence of ARBSI between the epidemic period and the control period [χ2=4.610, relative risk (RR)=2.575, 95% confidence interval (CI) (1.053, 6.298), P=0.032]. There was no statistically significant difference in the incidence of LASI and ARBSI at different stages in patients with arteriovenous fistula and unnel-cuffed catheters (TCC) (P>0.05). There were statistically significant differences in the incidence of LASI [χ2=4.898, RR=3.832, 95%CI (1.058, 13.885), P=0.027] and ARBSI [χ2=7.150, RR=4.684, 95%CI (1.333, 16.460), P=0.005] among non cuffed catheters (NCC) patients at different stages. TCC patients might experience LASI (P<0.05) during the epidemic period and ARBSI (P<0.05) during the control period compared with the arteriovenous fistula patients; both central venous catheterization and NCC patients might experience LASI and ARBSI during the control period (P<0.05). Conclusion Targeting COVID-19 prevention may be associated with the reduction of vascular access infection in hemodialysis patients, in particular in NCC patients.
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.
Objective To investigate the mediating effect of phase angle between muscle strength and muscle function in maintenance hemodialysis (MHD) patients, aiming to provide a reference basis for clinical improvement of muscle strength and muscle function in MHD patients. Methods Random sampling was used to collect patients undergoing outpatient MHD in the Wenjiang Hemodialysis Room of the Department of Nephrology, West China Hospital, Sichuan University between September and December 2023 as the subjects of this study. Muscle strength was assessed by handgrip strength, muscle function was assessed by Short Physical Performance Battery (SPPB), and phase angle was measured by bioelectrical impedance analysis. The mediating effect of phase angle between muscle strength and muscle function was analyzed. Results A total of 239 MHD patients were included, including 125 males (52.3%) and 114 females (47.7%). The mean phase angle of MHD patients was (5.77±1.17)°, 89 patients (37.2%) showed decreased muscle strength, and 109 patients (45.6%) showed muscle hypoplasia. Spearman’s correlation analyses showed that phase angle was significantly and positively correlated with both handgrip strength and SPPB in MHD patients (P<0.001). The results of mediation effect analysis showed that handgrip strength was able to positively predict phase angle (β=0.535, P<0.001); handgrip strength was able to positively predict SPPB (β=0.481, P<0.001); phase angle was able to positively predict SPPB (β=0.296, P<0.001); and when both handgrip strength and phase angle entered in the regression equation, both handgrip strength (β=0.392, P<0.001) and phase angle (β=0.165, P<0.05) could positively predict SPPB. Phase angle in MHD patients partially mediated the association between muscle strength and muscle function, with the mediating effect accounting for 32.5% of the total effect. Conclusions There is a close relationship between phase angle, muscle strength and muscle function in MHD patients, and muscle strength can affect muscle function directly or indirectly through phase angle. Medical professionals should pay attention to the muscle function of MHD patients and further improve their muscle function by improving their phase angle and muscle strength.
Central venous stenosis is a common complication following long-term dialysis catheter placement in dialysis patients. Generally, percutaneous angioplasty is the treatment of choice, and venous stent implantation should be considered in different situations. However, the venous stent migrating into right atrium is a rare but fatal complication. We presented a patient whose superior vena cava stents migrated into right atrium, resulting in acute tamponade, and exploratory thoracotomy was proceeded.
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.
