Background
Malnutrition, sedentary lifestyle, cognitive dysfunction and poor psychological well‐being are often reported in patients on haemodialysis (HD).
Aims
We aimed to explore needs, barriers ...and facilitators—as perceived by patients, their carers, and healthcare professionals (HCPs) for increasing the adherence to the diet, to physical activity and cognition and psychological well‐being.
Methods
This is an observational cross‐sectional study following the STROBE statement. This study is part of an ERASMUS+ project, GoodRENal—aiming to develop digital tools as an educational approach to patients on HD. For that, the GoodRENal comprises HD centers located in four Belgium, Greece, Spain and Sweden. Exploratory questionnaires were developed regarding the perceived needs, barriers and facilitators regarding the diet, physical activity, cognition and psychological well‐being from the perspective of patients, their carers and HCPs.
Results
In total, 38 patients, 34 carers and 38 HCPs were included. Nutrition: For patients and carers, the main needs to adhere to the diet included learning more about nutrients and minerals. For patients, the main barrier was not being able to eat what they like. Physical activity: As needs it was reported information about type of appropriate physical activity, while fatigue was listed as the main barrier. For Cognitive and emotional state, it was perceived as positive for patients and carers perception but not for HCPs. The HCPs identified as needs working as a team, having access to specialised HCP and being able to talk to patients in private.
Conclusions
Patients and their carers listed as needs guidance regarding nutrition and physical activity but were positive with their cognitive and emotional state. The HCPs corroborated these needs and emphasised the importance of teamwork and expert support.
Background: Individuals with chronic kidney disease (CKD) often experience reduced muscle strength and diminished health-related quality of life (HRQoL), and engaging in regular exercise may improve ...them. The aim of this study was to assess the effect of intradialytic exercise using non-immersive virtual reality (VR) on body composition of patients with CKD on hemodialysis (HD). Methods: This was a substudy in a clinical trial of intradialytic exercise intervention using a non-immersive VR game in which the patient interacted by moving the lower limbs. Body composition was determined by BCM Fresenius multifrequency stereoscopic bioimpedance. Body mass index (BMI), fat tissue index (FTI), lean tissue index (LTI), extracellular/intracellular water (EIW), and phase angle (PA) were recorded in 52 patients, 24 in the control group (CG) and 28 in the exercise group (EG). Results: Statistically significant differences were observed between both groups. The LTI increased in the EG while it decreased in the CG. The FTI and the EIW decreased in the EG compared to the increase observed in the CG. Conclusions: Intradialytic exercise using non-immersive VR was associated with an increase in LTI and a decrease in FTI of CKD patients on HD.
Abstract
Background
Chronic kidney disease is closely related to a high risk of death and disability, poor physical performance and frailty. The main objective of this research was to analyse how ...intradialytic administration of a non-immersive virtual reality (VR) exercise programme would affect physical function and adherence to exercise in these patients.
Methods
A total of 56 individuals participated in two 12-week periods in a crossover randomized controlled trial. Each patient underwent a functional capacity evaluation before and after each study period. The functional tests administered included the 4-m gait speed test, Short Physical Performance Battery (SPPB), timed up-and-go (TUG) test, one-legged stance test (OLST) for balance, sit-to-stand 10 (STS-10) and sit-to-stand 60 (STS-60) tests and 6-min walking test (6MWT). Adherence to the exercise programme was also recorded. To assess the effect of VR exercise on the functional test outcomes over time, the patients were analysed using a two-way repeated-measures analysis of variance with time and treatment as the within-participant factors.
Results
By the end of the 12 weeks of exercise, compared with the control period, 33 participants showed significant change in physical function as measured through the 4-m gait speed test (0.14 m/s), SPPB (1.2 points), TUG (−1.7 s), OLST (7.1 s), STS-10 (−5.8 s), STS-60 (5 repetitions) and 6MWT (85.2 m), with adherence rates exceeding 70%. There were no changes in the biochemical data or in the medications in the period of the study.
Conclusion
An intradialytic non-immersive VR exercise programme improves patient physical function.
Abstract
Background
Engagement in exercise by haemodialysis (HD) patients has been shown to generate benefits both in terms of improved functional capacity and in the health-related quality of life. ...The use of non-immersive virtual reality (VR) games represents a new format for the implementation of intradialysis exercise. Some studies have shown that engaging in exercise for 6 months reduces the consumption of antihypertensive drugs and decreases the time spent admitted to hospital among individuals receiving HD treatments. The objective of this study was to evaluate changes in the consumption of healthcare resources and micro-costing for patients on HD who completed a VR exercise program.
Materials and methods
Design: This study is a secondary analysis of a clinical trial. The participants performed an intradialysis exercise program with non-immersive virtual reality for 3 months. The variables were recorded in two periods: 12 months before and 12 months after the start of the exercise program.
Results
The micro-costing analysis showed a significant decrease in the mean cost, in euros, for the consumption of laboratory tests − 330 (95% CI:− 533, − 126;
p
= 0.003), outpatient visits − 351 (− 566, − 135;
p
= 0.003), and radiology tests − 111 (− 209, − 10;
p
= 0.03) in the 12 months after the implementation of the exercise program relative to the 12 months prior to its start.
Conclusion
The implementation of intradialysis exercise programs decreased the expenditure of some healthcare resources. Future studies could help clarify if longer interventions would have a stronger impact on these cost reductions.
Background
Chronic kidney disease patients on hemodialysis treatment are characterized by increased levels of inflammatory markers and oxidative stress, in addition to a significant deterioration in ...physical function. The benefits of physical exercise on the functional capacity of this patients are well known; however, it can also improve the endogenous antioxidant defense system and the inflammatory state, but still very few studies have been carried out. This is the first study to analyze the effect of a 4-month exercise program with combined aerobic and strength training in patients undergoing hemodialysis, under two modalities.
Methods
Seventy-one patients undergoing hemodialysis were enrolled and randomized in two groups, one of them performing an intra-dialysis exercise program (
n =
36), and the other carrying out a home-based exercise program (
n =
35). Serum levels of oxidative stress and inflammation biomarkers were determined before and after the intervention.
Results
IL-6 plasma levels showed a significant decrease in the intra-dialysis group after exercise (42.61 ± 9.21 to 26.40 ± 7.84,
p =
0.03), while CRP levels decreased significantly in the home-based group (16.12 ± 24.18 to 8.50 ± 11.28,
p =
0.03). MCP-1, TNF-α, ICAM-1 and the oxidative stress markers MDA, GSH and GSSG, did not undergo significant changes after the intervention.
Conclusion
Four months of combined strength and aerobic endurance exercise improve the inflammatory status of hemodialysis patients by significantly reducing IL-6 levels in those subjects who perform intra-dialysis exercise and CRP levels in those who do it at home.
Background: Exercise improves the physical function of people suffering from chronic kidney disease on hemodialysis (HD). Virtual reality is a new type of intradialysis exercise that has a positive ...impact on physical function. Intradialysis exercise is recommended during the first 2 h, but its safety in the last part of the dialysis session is unknown. Methods: This was a pilot sub-study of a clinical trial. Several hemodynamic control variables were recorded, including blood pressure, heart rate, and intradialytic hypotensive events. These variables were recorded during three different HD sessions, one HD session at rest, another HD session with exercise during the first two hours, and one HD session with exercise during the last 30 min of dialysis. The intradialysis virtual reality exercise was performed for a maximum of 30 min. Results: During exercise sessions, there was a significant increase in heart rate (6.65 (4.92, 8.39) bpm; p < 0.001) and systolic blood pressure (6.25 (0.04,12.47) mmHg; p < 0.05). There was no difference in hemodynamic control between the sessions with exercise during the first two hours and the sessions with exercise during the last 30 min. There was no association between intra-dialytic hypotensive events at rest (five events) or exercise at any point (two vs. one event(s), respectively). Conclusion: performing exercise with virtual reality at the end of a hemodialysis session is not associated with hemodynamic instability.
It has been suggested that physical exercise in chronic hemodialysis could improve dialysis dose and reduce postdialysis rebound. A randomized controlled trial was performed to compare a group of ...patients doing physical exercise during the first 2 h of hemodialysis sessions and another group doing physical exercise at home. The descriptive variables, dialysis doses measured by KtV, and rebounds (urea, creatinine, potassium, phosphorus), were recorded. For 69 patients: the mean KtV was 1.84; the 30‐min rebound of creatinine was 32.37%, urea 24.39%, potassium 15.31%, and phosphorus 51.29%. For each patient, the basal measurement was compared with those determined when performing physical exercise; no statistically significant differences were observed between the changes determined to dose and rebound in the group with hemodialysis exercise compared to those of the home exercise group. In conclusion, performing physical exercise during the first 2 hours of hemodialysis sessions neither lowered postdialysis molecules rebound nor improved dialysis dose.
La activación del paciente es un concepto que se refiere a la voluntad de gestionar su salud y atención médica. Para evaluarla, se ha desarrollado y validado una medida de activación del paciente ...(PAM). Diversos estudios informan baja activación en pacientes con enfermedades crónicas. No obstante, la información sobre activación de pacientes en tratamiento con hemodiálisis es escasa. El objetivo del presente estudio es describir el nivel de activación de pacientes en tratamiento crónico de una unidad de hemodiálisis (HD) y su relación con los parámetros de control de la enfermedad.
Estudio observacional transversal en pacientes con enfermedad renal crónica avanzada en tratamiento crónico con HD. Se incluyeron 96 pacientes. La activación se midió con el cuestionario PAM-13. Se estudió su relación con variables descriptivas (edad, sexo, comorbilidad, estudios, hábitat) y variables de control de la enfermedad (acceso vascular, flujo sangre, potasemia, fosfatemia, ganancia interdialítica). Para ello se emplearon como métodos estadísticos la prueba de correlación de Spearman, modelo de retrogresión lineal múltiple y modelo logístico.
La puntuación media (desviación estándar SD) de PAM-13 fue de 63,19 (15,21). La activación se asociaba significativamente con el acceso vascular (p = 0,003), flujo de sangre (p = 0,024), y ganancia interdialítica de los pacientes (p = 0,008).
La activación de pacientes en tratamiento crónico con hemodiálisis es baja. Una mayor activación se relaciona con disponer de fístula arteriovenosa, con mayor flujo sanguíneo y con menor ganancia interdialítica. Son necesarios futuros estudios que confirmen y apliquen nuestros resultados.
Patient activation is a concept that refers to the willingness to manage one's health and medical care. To assess it, a patient activation measure (PAM) has been developed and validated. Several studies report low activation in patients with chronic diseases. However, information on activation in hemodialysis patients is scarce. The aim of the present study is to describe the activation level of patients on chronic treatment in an HD unit and its relationship with disease control parameters.
Cross-sectional observational study in patients with advanced chronic kidney disease on chronic HD treatment. Ninety-six patients were included. Activation was measured with the PAM-13 questionnaire. Its relationship with descriptive variables (age, sex, comorbidity, studies, habitat) and disease control variables (vascular access, blood flow, potassaemia, phosphataemia, interdialytic gain) was studied. For this purpose, Spearman's correlation test, multiple linear regression model and logistic model were used as statistical methods.
The mean (SD) PAM-13 score was 63.19 (15.21). Activation was significantly associated with vascular access (P = .003), blood flow (P = .024), and interdialytic gain of patients (P = .008).
Activation in patients on chronic hemodialysis treatment is low. Higher activation is related having an arteriovenous fistula, higher blood flow and lower interdialytic gain. Future studies are needed to confirm and apply our results.
Renal replacement treatment has not been generalized to the elderly for different reasons. The main objective of the present cohort study is to compare survival in patients older than 80 years with ...chronic kidney disease stage 5 on renal replacement treatment with those on conservative treatment. The use of healthcare resources is compared too. A Cox proportional hazards regression analysis was run with the outcome variable death during the follow‐up period. The independent variables were treatment type, age, gender, smoking habit, serum albumin, hemoglobin, Charlson Index, diabetes mellitus, arterial hypertension, ischemic cardiopathy, and neoplasm. For outcome variable “death,” renal replacement treatment obtained a hazard ratio of 0.273 (P .006, CI95% 0.108‐0.686) vs conservative treatment. In conclusion, patients older than 80 years with chronic kidney disease stage 5 on renal replacement treatment presented a lower mortality risk than those receiving conservative treatment. Comorbidity and age are both associated with mortality, but do not cancel out the survival advantage. In healthcare resources, the renal replacement treatment group made greater use of tests, medical visits and consumption of hospital dispensing drugs, but there were no differences with respect to the days of hospital admission or assistance in home hospitalization.
The determination of Kt/V by ionic dialysance is a technique that has extended its use in hemodialysis clinics. The clinical guidelines have reflected the need to validate this method as a ...determinant of the dose of dialysis.
Determine in daily practice, the influence of hemodialysis characteristics and medication on Kt/V results by ionic dialysance (Kt/V OCM) and compare them with Kt/V measures by serum urea (Kt/V Daugirdas).
Cross-sectional and observational study. Participants: 127 patients on chronic hemodialysis. Measurements: Descriptive variables, study variables (Kt/VOCM, Kt/VDaugidas), and the variables that modified the effect (patient temperature, serum sodium, vascular access, recirculation, blood flow, hemodialysis technique, dialyzer, acid concentrate, conductivity, dialyzate flow).
The mean of Kt/V Daugirdas was 1.84 and the Kt/VOCM mean 1.65; Pearson's was CC r=0.54; P<0.001 and Lin CCC=0.48. In the linear regression, the variables related to hemodialysis technique showed no statistical association with the measurement obtained by Kt/VOCM. Monosodium phosphate and 20% sodium chloride dispensing were associated with a higher Kt/VOCM.
The different technical aspects noted during HD sessions do not influence Kt/V OCM outcomes. Kt/V determined by ionic dialysance isn’t similar to that determined by serum urea. When assessing dialysis doses measured by dialysance, consider that it is not the same as determined with serum urea, but it provides an approximation to estimate dialysis doses in real time. It is necessary to consider if drugs or supplements have been administered that can modify it when interpreting the results.
