AI-Guided Personalized Relaxation for Hemodialysis Patients

Patients undergoing maintenance hemodialysis frequently experience impaired health-related quality of life, anxiety, and difficulties in coping with the long-term demands of treatment. Artificial intelligence (AI)-guided interventions may provide personalized psychological support and promote adaptive coping through tailored relaxation strategies. This randomized controlled mixed-methods trial evaluates the effectiveness of an AI-guided personalized relaxation intervention delivered through a smartphone application among adults receiving maintenance hemodialysis. Participants are randomly assigned to either an intervention group receiving AI-guided personalized relaxation in addition to routine hemodialysis care or a control group receiving routine care alone. The 6-week intervention includes individualized breathing exercises, mindfulness practices, guided imagery, progressive muscle relaxation, and adaptive feedback generated according to participant characteristics, emotional responses, and engagement patterns. The primary outcome is health-related quality of life measured using the Kidney Disease Quality of Life-36 (KDQOL-36™). Secondary outcomes include anxiety symptoms measured by the Generalized Anxiety Disorder-7 (GAD-7), coping strategies measured by the Brief COPE Inventory, and user acceptance of the AI-guided intervention. Qualitative interviews are conducted with intervention participants to explore their experiences, perceived benefits, feasibility, and acceptability of the intervention. The study aims to determine whether AI-guided personalized relaxation can improve quality of life, reduce anxiety, and enhance coping among patients undergoing maintenance hemodialysis while providing insight into the acceptability and feasibility of integrating AI-supported psychosocial interventions into routine dialysis care. The personalization system incorporate a pre-trained facial emotion recognition model using the smartphone's front-facing camera. Facial expressions will analyze in real time to classify emotional states (e.g., anxious, neutral, or relaxed) and adapt relaxation recommendations. Facial images will not stored, and the feature will used solely for intervention personalization after informed consent. Sample size will estimated a priori using GPower (version 3.1) software for a two tailed analysis of difference between two independent means within -t- test family using the following parameters; effect size (Cohen's d = 0.64) which had been reported by Zhang et al. (2025), significance level of 0.05, a statistical power of 90%, and an allocation ratio of 1:1. The minimum sample size will require 106 participants (53 for each group). To compensate for an anticipated attrition rate of 20%, the sample size will increased to 128 participants (64 participants per group).

Tenapanor in Maintenance Hemodialysis Patients

The investigators hypothesize that Tenapanor can improve serum phosphorus control and regulate intestinal metabolism in maintenance hemodialysis patients without increasing the risk of severe gastrointestinal adverse events. Therefore, this study intends to take maintenance hemodialysis patients with hyperphosphatemia as the research object, prospectively observe patients receiving Tenapanor as part of their routine care, and clarify the real-world efficacy of Tenapanor for phosphorus management and its impact on intestinal metabolism in these patients.

Efficacy of pHA130 Hemoadsorption on Protein-Bound Uremic Toxins and Quality of Life in Kidney Failure

Patients on maintenance hemodialysis (MHD) face a high risk of cardiovascular mortality and reduced quality of life. Conventional high-flux hemodialysis (HD) is the standard of care but has limited efficacy in clearing middle-molecular and protein-bound uremic toxins (PBUTs). The accumulation of these toxins is associated with adverse long-term outcomes. This study evaluates the efficacy and safety of the pHA130 hemoadsorption cartridge, which utilizes a modified resin for enhanced PBUT adsorption, when combined with hemodialysis (HAHD). This is a prospective, open-label, multi-center, randomized controlled trial involving 100 MHD patients. Participants will be randomized 1:1 to either the HAHD group (receiving one HAHD session using the pHA130 cartridge and two standard HD sessions weekly) or the Control group (receiving three standard HD sessions weekly). The primary objective is to assess the reduction in serum indoxyl sulfate (IS) and p-cresol sulfate (PCS) levels from baseline to 12 months. Secondary objectives include evaluating changes in quality of life (KDQoL-SF, MMSE), the progression of coronary artery calcification (CAC), the incidence of major adverse cardiovascular events (MACEs), all-cause mortality, and safety profiles. This trial aims to determine if integrating long-term HAHD therapy can optimize blood purification strategies for the MHD population.

Impact of APP-assisted Patient Management on the Quality Control of Blood Purification Therapy

Many maintenance hemodialysis (MHD) patients develop negative outlooks due to their illnesses and complications, making their quality of life and prognosis a clinical concern. Effective life management and treatment cooperation are crucial to improving dialysis quality and patient outcomes. This trial aims to evaluate whether management through the "Yueya" mini-program and WeChat can provide personalized guidance such as health education, diet, exercise, medication supervision, and condition monitoring to enhance treatment compliance, quality of life, strengthen quality control in the hemodialysis unit, and improve patient prognosis. Patients will be divided into a group receiving support via the "Yueya" mini-program and WeChat, and a control group receiving routine care. Clinical and laboratory indicators, cardiovascular events, death, hospitalization, quality of life, and compliance will be recorded and compared between groups to assess the impact of APP-assisted patient management on the quality of MHD blood purification therapy and the prognosis of MHD patients.
