UNASSIGNED: In the wake of the coronavirus disease 2019 (COVID-19) pandemic, the United States federal government expanded originating telemedicine sites to include outpatient dialysis units. For the first time, nephrology practitioners across the United States could replace face-to-face visits with telemedicine for patients receiving in-center hemodialysis. This study describes patients\' perspectives on the use of telemedicine during in-center hemodialysis.
UNASSIGNED: A qualitative study.
UNASSIGNED: Thirty-two patients from underserved populations (older, less educated, unemployed, persons of color) receiving in-center hemodialysis who used telemedicine with their nephrologist during the COVID-19 pandemic.
UNASSIGNED: Telephone semistructured interviews were conducted in English or Spanish. Transcripts were thematically analyzed.
UNASSIGNED: We identified 6 themes with subthemes: adapting to telemedicine (gaining familiarity and confidence, overcoming and resolving technical difficulties, and relying on staff for communication); ensuring availability of the physician (enabling an immediate response to urgent medical needs, providing peace of mind, addressing patient needs adequately, and enhanced attention and contact from physicians); safeguarding against infection (limiting COVID-19 exposures and decreasing use); straining communication and physical interactions (loss of personalized touch, limited physical examination, and unable to reapproach physicians about forgotten issues); maintaining privacy (enhancing privacy and projecting voice enables others to hear); and supporting confidence in telemedicine (requiring established rapport with physicians, clinical stabilty of health, and ability to have in-person visits when necessary).
UNASSIGNED: Interviews were conducted later in the pandemic when some nephrology care providers were using telemedicine infrequently.
UNASSIGNED: Patients receiving in-center hemodialysis adapted to telemedicine visits by their nephrologists in the context of the COVID-19 pandemic and observed its benefits. However, further considerations regarding communication, privacy, and physical assessments are necessary. Integrating telemedicine into future in-center hemodialysis care using a hybrid approach could potentially build trust, optimize communication, and augment care.
This study describes patients’ perspectives on the use of telemedicine while receiving in-center hemodialysis during the coronavirus disease 2019 (COVID-19) pandemic. Data are derived from semistructured interviews with thirty-two patients from underserved populations (older, less educated, unemployed, persons of color). We identified 6 major themes including adapting to telemedicine, ensuring availability of the physicians, safeguarding against infection, straining communication and physical interactions, maintaining privacy, and supporting confidence in telemedicine. These findings suggest that patients receiving in-center hemodialysis adapted to telemedicine visits by their nephrologists in the context of the COVID-19 pandemic and observed its benefits. However, further considerations regarding communication, privacy, and physical assessments are necessary. Integrating telemedicine into future in-center hemodialysis care using a hybrid approach could potentially build trust, optimize communication, and augment care.

We have launched a pilot study, called DIADIDEAL, to propose nurse-assistance at home for arterio-venous fistula (AVF) cannulation in home hemodialysis (HHD) patients. The aim of the present study was to describe enrollment of the patients and their nurses.
All prevalent HD patients on 30th November 2018 with no medical contraindication to HDD treatment and all incident patients on dialysis from the 30th November 2018 to the 21st April 2023 were eligible.
Among 155 prevalent HD patients, 4 patients were included. Among the 276 incident patients on dialysis during the study period, 6 were included. We have phoned 23 nurse centers during the recruitment period. Eight of them agreed to learn in our unit how to cannulate AVF; 27 private nurses were enrolled.
The results of the DIADIDEAL study will be available in 2024; we hope it will lead to a reimbursement of nurse-AVF cannulation at home in HDD.

Tous les patients prévalents en HD au 30 novembre 2018 n’ayant pas de contre-indication médicale à un traitement par HDD ainsi que tous les patients incidents en dialyse du 30 novembre 2018 au 21 avril 2023 étaient éligibles.
Parmi les 155 patients prévalents en hémodialyse, 4 ont été inclus. Parmi les 276 patients incidents en dialyse sur la période, 6 ont été inclus dans l’étude. Parmi les 23 cabinets IDEL contactés pour l’étude, 8 ont accepté et 27 IDEL ont été formés à la ponction de FAV.
Les résultats de l’étude DIADIDEAL seront disponibles en 2024 et viseront à obtenir une nomenclature pour l’acte de ponction de FAV par les IDEL.

BACKGROUND: Self-efficacy of patients on hemodialysis is considered a main component of the successful management of chronic kidney diseases. The self-efficacy of these patients may be influenced by many individual and social factors. This study aimed to assess the association between perceived self-efficacy and social support by patients on hemodialysis treatment and the resilience of their families.
METHODS: This cross-sectional study was conducted on 183 patients and 183 families of hemodialysis patients in the largest hemodialysis center in northwest of Iran. Data was collected from July to December 2021 using chronic kidney disease self-efficacy, multidimensional perceived social support (MSPSS), and the Walsh family resilience questionnaire (WFRQ). The collected data were analyzed by SPSS software using descriptive and inferential statistical tests.
RESULTS: The findings showed that the mean score of patients\' self-efficacy was 171.63 ± 38.19 in a possible range of 25 to 250. Moreover, the mean score of perceived social support was 62.12 ± 16.12 in a possible range of 7 to 84. The mean total score of family resilience was 119.08 ± 26.20 in a possible range of 32 to 84. Also, the results of the study showed a positive and significant relationship between the self-efficacy of patients with their perceived social support and the resilience of their families (p < 0.01).
CONCLUSIONS: The results of the study showed that there is a significant relationship between patient self-efficacy and family resilience and social support received in chronic kidney patients undergoing hemodialysis. Therefore, it is suggested to consider practical strategies in the field of family resilience and social support to improve patients\' self-efficacy.

UNASSIGNED: Fluid and salt overload in patients on dialysis result in high blood pressure (BP), left ventricular hypertrophy (LVH) and hemodynamic instability, resulting in cardiovascular morbidity.
UNASSIGNED: Analysis of 910 pediatric patients on maintenance hemodialysis/hemodiafiltration (HD/HDF), prospectively followed-up with 2758 observations recorded every 6-months in the International Pediatric Hemodialysis Network (IPHN).
UNASSIGNED: Uncontrolled hypertension was present in 55% of observations, with 27% of patients exhibiting persistently elevated predialysis BP. Systolic and diastolic age- and height-standardized BP (BP-SDS) were independently associated with the number of antihypertensive medications (odds ratio [OR] = 1.47, 95% confidence interval 1.39-1.56, 1.36 [1.23-1.36]) and interdialytic weight gain (IDWG; 1.19 [1.14-1.22], 1.09 [1.06-1.11]; all P < 0.0001). IDWG was related to urine output (OR = 0.27 [0.23-0.32]) and dialysate sodium (dNa; 1.06 [1.01-1.10]; all P < 0.0001). The prevalence of masked hypertension was 24%, and HD versus HDF use was an independent risk factor of elevated age- and height-standardized mean arterial pressure (MAP-SDS) (OR = 2.28 [1.18-4.41], P = 0.01). Of the 1135 echocardiograms, 51% demonstrated LVH. Modifiable risk factors included predialysis systolic BP-SDS (OR = 1.06 [1.04-1.09], P < 0.0001), blood hemoglobin (0.97 [0.95-0.99], P = 0.004), HD versus HDF modality (1.09 [1.02-1.18], P = 0.01), and IDWG (1.02 [1.02-1.03], P = 0.04). In addition, HD modality increased the risk of LVH progression (OR = 1.23 [1.03-1.48], P = 0.02). Intradialytic hypotension (IDH) was prevalent in patients progressing to LVH and independently associated with predialysis BP-SDS below 25th percentile, lower number of antihypertensives, HD versus HDF modality, ultrafiltration (UF) rate, and urine output, but not with dNa.
UNASSIGNED: Uncontrolled hypertension and LVH are common in pediatric HD, despite intense pharmacologic therapy. The outcome may improve with use of HDF, and superior anemia and IDWG control; the latter via lowering dNa, without increasing the risk of IDH.

Despite numerous studies on the effect of each dialysis modality on mortality, the issue remains controversial. We investigated the hazard rate of mortality in patients with incident end-stage renal disease (ESRD) concerning initial dialysis modality (hemodialysis vs. peritoneal dialysis). Using a nationwide, multicenter, prospective cohort in South Korea, we studied 2207 patients, of which 1647 (74.6%) underwent hemodialysis. We employed the weighted Fine and Gray model over the follow-up period using inverse probability of treatment and censoring weighting. Landmark analysis was used for identifying the changing effect of dialysis modality on individuals who remained event-free at each landmark point. No significant difference in hazard rate was observed overall. However, the peritoneal dialysis group had a significantly higher hazard rate than the hemodialysis group among patients under 65 years after 4- and 5- year follow-up. A similar pattern was observed among those with diabetes mellitus. Landmark analysis also showed the higher hazard rate for peritoneal dialysis at 2 years for the education-others group and at 3 years for the married group. These findings may inform dialysis modality decisions, suggesting a preference for hemodialysis in young patients with diabetes, especially for follow-ups longer than 3 years.

UNASSIGNED: Despite a lack of clinical trial data, β-blockers are widely prescribed to dialysis patients. Whether specific β-blocker agents are associated with improved long-term outcomes compared with alternative β-blocker agents in the dialysis population remains uncertain.
UNASSIGNED: We analyzed data from an international cohort study of 10 125 patients on maintenance hemodialysis across 18 countries that were newly prescribed a β-blocker medication within the Dialysis Outcomes and Practice Patterns Study (DOPPS). The following β-blocker agents were compared: metoprolol, atenolol, bisoprolol and carvedilol. Multivariable Cox proportional hazards models were used to estimate the association between the newly prescribed β-blocker agent and all-cause mortality. Stratified analyses were performed on patients with and without a prior history of cardiovascular disease.
UNASSIGNED: The mean (standard deviation) age in the cohort was 63 (15) years and 57% of participants were male. The most commonly prescribed β-blocker agent was metoprolol (49%), followed by carvedilol (29%), atenolol (11%) and bisoprolol (11%). Compared with metoprolol, atenolol {adjusted hazard ratio (HR) 0.77 [95% confidence interval (CI) 0.65-0.90]} was associated with a lower mortality risk. There was no difference in mortality risk with bisoprolol [adjusted HR 0.99 (95% CI 0.82-1.20)] or carvedilol [adjusted HR 0.95 (95% CI 0.82-1.09)] compared with metoprolol. These results were consistent upon stratification of patients by presence or absence of a prior history of cardiovascular disease.
UNASSIGNED: Among patients on maintenance hemodialysis who were newly prescribed β-blocker medications, atenolol was associated with the lowest mortality risk compared with alternative agents.

OBJECTIVE: 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.
METHODS: 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.
RESULTS: The mean (SD) PAM-13 score was 63.19 (15.21). Activation was significantly associated with vascular access (P = 0.003), blood flow (P = 0.024), and interdialytic gain of patients (P = 0.008).
CONCLUSIONS: 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.

Difelikefalin is to date the first and only specific treatment to be approved for the treatment of moderate-to-severe chronic kidney disease-associated pruritus (CKD-aP) in adult patients on hemodialysis.
This was a retrospective, single-center, real-life study in hemodialysis patients with CKD-aP treated with difelikefalin. The primary objective was to evaluate the evolution of the intensity of pruritus during treatment with difelikefalin using the Worst Itch Intensity-Numerical Rating Scale (WI-NRS). Adult patients were included if they had been on hemodialysis for at least 3 months and were suffering from moderate to severe CKD-aP (objectified by the WI-NRS score) for which difelikefalin had been prescribed.
11 patients (7 men and 4 women; mean age, 63.8 years) with a mean (SD) weekly dialysis time of 13 h (2.4) were included. The mean hemodialysis duration was 5 (3.6) years and the mean pruritus duration was 4.3 (3.2) years. At inclusion, on-going treatments of CKD-aP were emollients in all patients and antihistamines in 9 patients. The mean WI-NRS score was 7.4 (1.1) at initiation of difelikefalin. At last assessment after a median follow-up of 9.0 months, the mean change of WI-NRS score was -5.1 (2.9) and 82% of patients had a decrease ≥ 3 points. Mild to moderate adverse reactions to difelikefalin were reported in 4 patients, all of whom recovered without sequelae.
These results show that difelikefalin, prescribed according to its therapeutic indication, is effective in the treatment of CKD-aP under real-life conditions, outside the controlled conditions of a clinical trial.
La difélikéfaline est à ce jour le premier et le seul traitement spécifique approuvé pour le traitement du prurit d’intensité modérée à sévère associé à la maladie rénale chronique (Pa-MRC) chez les patients adultes hémodialysés.
Il s’agit d’une étude rétrospective, monocentrique, en vie réelle, chez des patients hémodialysés souffrant de Pa-MRC et traités par difélikéfaline. L’objectif principal était d’évaluer l’évolution de l’intensité du prurit au cours du suivi à l’aide de l’échelle WI-NRS (Worst Itch Intensity-Numerical Rating Scale). Les patients adultes ont été inclus s’ils étaient hémodialysés depuis au moins trois mois et souffraient d’un Pa-MRC modéré à sévère (objectivé par le score WI-NRS) pour lequel la difélikéfaline avait été prescrite.
Onze patients (7 hommes et 4 femmes ; âge moyen : 63,8 ans) avec un temps de dialyse hebdomadaire moyen (SD) de 13 h (2,4) ont été inclus. La durée moyenne d’hémodialyse était de 5 ans (3,6) et la durée moyenne de prurit de 4,3 ans (3,2). À l’inclusion, les traitements du prurit en cours étaient des émollients pour tous les patients et des antihistaminiques pour 9 d’entre eux. Le score WI-NRS moyen était de 7,4 (1,1) au début du traitement par la difélikéfaline. À la dernière évaluation, après un suivi médian de 9 mois, la variation moyenne du score WI-NRS était de -5,1 (2,9) et 82 % des patients avaient une diminution ≥ 3 points. Des effets indésirables d’intensité légère à modérée liés à la difélikéfaline ont été rapportés chez 4 patients, tous rétablis sans séquelles.
Ces résultats montrent que la difélikéfaline, prescrite conformément à son indication thérapeutique, est efficace en vie réelle dans le traitement du Pa-MRC, en dehors des conditions contrôlées d’un essai clinique.

UNASSIGNED: This study was performed to investigate and compare the effects of intradialytic core stabilization and aerobic exercises on physical performance, fatigue, quality of life and dialysis adequacy.
UNASSIGNED: The study involved 39 individuals on hemodialysis randomized into two groups: aerobic exercise (AE, n = 20) and core stabilization (CSE, n = 19). Over 8 weeks, the AE group performed pedal ergometer exercises, while the CSE group performed 4-phase core stabilization exercises. Physical performance (five times sit to stand test, 2-min step test), quality of life (Kidney Disease Quality of Life-36; KDQOL-36), fatigue levels (Piper Fatigue Scale), and dialysis adequacy (Kt/V and URR) were assessed.
UNASSIGNED: After training, a significant improvement was observed in the physical performance, fatigue levels, and some parameters of KDQOL-36 of the patients (p < 0.05). However, no significant changes were observed in dialysis adequacy indicators (Kt/V and URR) (p > 0.05). When the amount of development obtained in both treatment groups is compared, kidney disease burden only in the subparameter of KDQOL-36 was statistically significantly improved in the CSE group compared to the AE group (p < 0.05).
UNASSIGNED: According to the results of the study, intradialytic core stabilization exercises appear to have similar effects to aerobic exercises and can be performed by HD patients.
Core stabilization exercises and aerobic exercises performed during dialysis are well tolerated by hemodialysis patients.Over eight weeks, intradialytic core stabilization and aerobic exercises are effective in improving physical performance, fatigue level, and quality of life in hemodialysis patients.In hemodialysis patients, eight weeks of intradialytic core stabilization and aerobic exercises are not sufficient to improve dialysis adequacy.It is recommended to include intradialytic core stabilization and aerobic exercises in the rehabilitation of hemodialysis patients.
