Objective
This study aimed to evaluate a behavioral intervention conducted with nondialyzed overweight women with chronic kidney disease (CKD) by describing their eating behaviors.
Design and Methods
This prospective, mixed-method, noncontrolled clinical trial used a behavioral nondiet approach with 15 multisession group interventions for dietary management among 33 overweight women with CKD (age = 62.0 [54.0-67.5] years; body mass index = 32.8 [30.5-38.6] kg/m2; estimated glomerular filtration rate = 28.0 [20.0-31.5] mL/min/1.73 m3). Thematic content analysis was performed using qualitative data from focus groups conducted before and after the intervention. Combined quantitative and qualitative methods were triangulated using data from the Intuitive Eating Scale-2.
Results
Eight categories emerged from the preintervention (factors that influence eating and living, diet culture, feelings of ambivalence and/or stagnation, and understanding one's limitations) and postintervention periods (appreciation for the different approach, awakening self-confidence, eating attunement, and discovering a new way to eat). The Intuitive Eating Scale-2 factors concur with the preintervention and postintervention categories, contributing to the transition from a less to more intuitive eating profile.
Conclusion
Behavioral intervention raised positive eating experiences that aligned with a more intuitive way of eating. Patients felt more empowered to accept and manage the disease. These results may contribute to changes in the adherence paradigm in nondialysis CKD.

Objective
Patients with end-stage renal disease are predisposed to low muscle mass (LMM) and myosteatosis. This study aimed to investigate the predictive value of LMM and myosteatosis, as assessed by computed tomography (CT), in predicting clinical outcomes following kidney transplantation.
Methods
A systematic search of PubMed, EMBASE, and the Cochrane Library was conducted to retrieve relevant English-language studies. Eligible studies reported on the associations of LMM and myosteatosis, determined via CT scan, with clinical outcomes in kidney transplant recipients. The primary outcomes were patient and graft survival.
Results
A total of 13 studies involving 2,764 kidney transplant recipients were included. The pooled prevalence of LMM was 28% (95% confidence interval [CI]: 0.16–0.40, I2 = 98%), while that of myosteatosis was 24% (95% CI: 0.16–0.33, I2 = 96%). LMM was significantly associated with an increased risk of patient mortality (hazard ratio [HR] = 2.08, 95% CI: 1.62–2.67, I2 = 13%) and graft loss (HR = 1.43, 95% CI: 1.03–1.98, I2 = 0%). Furthermore, LMM was linked to an increased incidence of hospital readmissions within 1 month (odds ratio = 2.05, 95% CI: 1.41–3.00, I2 = 0%) and 3 months (odds ratio = 1.78, 95% CI: 1.25–2.52, I2 = 0%). Recipients with myosteatosis also demonstrated a significantly increased risk of mortality (HR = 1.82, 95% CI: 1.24–2.67, I2 = 7%) and graft loss (HR = 1.99, 95% CI: 1.21–3.26, I2 = 0%).
Conclusion
LMM and myosteatosis are prevalent in kidney transplant recipients and significantly impact prognosis. Comprehensive utilization of preoperative CT-derived muscle mass and density data may facilitate early risk stratification and inform clinical decision-making.

Objectives
This study investigated serum selenium and zinc levels across three groups of chronic kidney disease patients and examined their associations with inflammation, nutrition parameters, and erythropoiesis-stimulating agent response.
Methods
This retrospective cross-sectional study included 298 patients (98 hemodialysis (HD), 92 peritoneal dialysis (PD), and 108 predialysis). We analyzed demographic data andlaboratory parameters, including selenium, zinc, hemoglobin, and erythropoietin resistance index (ERI). Multivariable linear regression analyses evaluated independent associations between trace elements and ERI while controlling for potential confounders.
Results
Selenium levels were significantly lower in PD patients compared to HD and predialysis patients, while zinc levels were highest in HD patients. In PD patients, selenium demonstrated a significant negative correlation with ERI (r = −0.32, P = .009), which remained significant in multivariable regression analysis (β = −0.13, P = .008) after adjusting for confounders. Partial correlation analysis revealed significant positive associations between urine output and selenium levels in PD (rp = .29, P = .005) and predialysis patients (rp = .21, P = .028). Albumin showed positive correlations with selenium across all groups.
Conclusions
Selenium and zinc levels vary significantly across patient groups. Selenium levels showed a significant independent negative correlation with ERI in PD patients, suggesting its potential involvement in erythropoiesis. The association between selenium and nutritional markers suggests that nutritional status plays a crucial role in maintaining adequate trace element levels. Residual renal function appears to significantly influence selenium levels, particularly in PD patients.
目的：本研究调查了三组慢性肾病患者的血清硒和锌水平，并研究了它们与炎症、营养参数和促红细胞生成剂（ESA）反应的关系。方法：回顾性横断面研究纳入298例患者（血液透析98例，腹膜透析92例，透析前108例）。我们分析了人口统计学数据、实验室参数，包括硒、锌、血红蛋白和红细胞生成素抵抗指数（ERI）。多变量线性回归分析评估了微量元素和ERI之间的独立关联，同时控制了潜在的混杂因素。结果：腹膜透析患者的硒水平明显低于血液透析和透析前患者，而锌水平在血液透析患者中最高。在腹膜透析患者中，硒与ERI呈显著负相关（r = -0.32, p = 0.009），在校正混杂因素后，在多变量回归分析中仍然显著（β = -0.13, p = 0.008）。偏相关分析显示，腹膜透析患者（rp = 0.29, p = 0.005）和透析前患者（rp = 0.21, p = 0.028）尿量与硒水平呈显著正相关。白蛋白与硒呈显著正相关。结论：不同患者组硒和锌水平差异显著。硒水平与腹膜透析患者ERI呈显著的独立负相关，提示其可能参与红细胞生成。硒与营养指标之间的关系表明，营养状况在维持足够的微量元素水平方面起着至关重要的作用。残余肾功能似乎显著影响硒水平，特别是在腹膜透析患者中。

Objective
To assess the association of residual diuresis with sarcopenia in patients with chronic kidney disease on hemodialysis.
Methods
Through a cross-sectional study, patients on hemodialysis were subjected to a Dual-Energy Radiologic Absorption examination to record muscle mass. Based on the volume of urine collected in 24 hours, patients were classified as anuric (diuresis ≤100 mL/day) or nonanuric (diuresis > 100 mL/day). Functional performance was evaluated by Short Physical Performance Battery (SPPB) and muscle strength by handgrip strength and 5-repetition sit-to-stand test. The association between the absence of residual urine and the presence of sarcopenia, low SPPB, and low muscle strength was analyzed using a binary logistic regression model.
Results
Ninety-two patients, with a mean age of 54.4 years (95% confidence interval [CI] 51.3-57.4) and with a mean diuresis volume of 476.3 mL/day (95% CI 320.4-632.2) were evaluated (48 anuric and 44 nonanuric). Anuric patients had a 2.77 (95% CI 1.14-6.73) times greater probability of sarcopenia and had a 3.55 (1.14-11.0) times greater probability of low SPPB regardless of gender, age, and time on dialysis. Gender was the other associated variable for the presence of sarcopenia, with males having a 3.30 (95% CI 1.34-8.13) times higher risk. There were no associations with muscle strength.
Conclusion
The absence of residual diuresis in patients on hemodialysis is associated with a higher risk of sarcopenia and low functional performance.

Objectives
This study aimed to (1) assess implementation of selected recommendations from the current clinical practice guideline for nutrition care in chronic kidney disease by registered dietitian nutritionists (RDNs) and (2) evaluate impact of a comprehensive guideline training on RDN practice.
Methods
We evaluated implementation of recommendations for subjective global assessment and intake of dietary protein, energy, phosphorus, and oral nutrition supplements (ONS). RDNs were randomized to receive standard knowledge-based guideline training or comprehensive training (standard training plus implementation training). Outcomes included congruence (consistency) between documented practice and guideline recommendations and RDN-reported guideline acceptability, adoption, and adaptation. Outcomes were descriptively analyzed, and odds of congruent care were compared by training group using multilevel logistic regression.
Results
Twenty-five RDNs from 28 US clinics documented nutrition care for 565 hemodialysis patients over 1,175 visits. Provided care was congruent or fully congruent with the guideline for almost all identified visits covering intake of protein (100% of visits), phosphorus (95%), and energy (95%) and most visits discussing ONS (69%). Most subjective global assessment components were rarely documented (<7% of visits) except for weight/weight change. Top RDN-reported acceptability factors were potential for positive impact on patients, strength of the evidence-base, and alignment with their current practice and skillsets. They noted more leadership level support was required to fully implement some recommendations (e.g., ONS). The comprehensive training did not improve odds of congruent care compared with standard training.
Conclusion
RDN documented practice was congruent with most selected guideline recommendations. A multilevel approach may improve implementation of recommendations.

Chronic kidney disease is a global health challenge, and effective, individualized nutritional management is crucial for slowing progression and improving quality of life. Artificial intelligence (AI) offers innovative tools to optimize and personalize nutritional care. This review explores AI applications in nutritional management, assessing their impact on clinical outcomes, quality of life, and care efficiency.
Methods
A systematic review was conducted, reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Searches were performed on 5 databases, namely MEDLINE, Embase, Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, and integrated with gray literature sources between September and November 2024. The methodological quality assessment was conducted independently by 2 researchers using the Joanna Briggs Institute methodology.
Results
Of 2,053 initial records, 7 studies met inclusion criteria. AI showed significant potential in personalizing dietary recommendations using machine learning, clinical decision support systems, and generative AI tools. These systems tailored nutritional advice based on patient-specific clinical data, reducing complications such as hyperkalemia and improving adherence. AI also facilitated early risk detection and proactive care by monitoring nutritional parameters and predicting complications. In addition, AI-powered platforms enhanced patient education through culturally relevant, intuitive dietary plans and multilingual materials, increasing engagement. AI also improved health care efficiency by automating tasks and integrating with electronic health records.
Conclusions
AI technologies show promise in enhancing nutritional care for patients with chronic kidney disease. Evidence supports their role in improving care quality and dietary adherence. Further research is needed to validate these technologies in clinical practice and ensure integration into routine care pathways.
