Nutritional Status Modifies the Association Between Hemoglobin Level and Mortality in Older Patients Undergoing Hemodialysis: A Nationwide Dialysis Registry in Japan
Kosugi T, Hasegawa T, Imaizumi T, Nishiwaki H, Honda H, Ito Y, Tsuruya K, Abe M, Hanafusa N and Kuragano T
Anemia is a common complication associated with adverse outcomes in older patients undergoing hemodialysis (HD). They also tend to experience malnutrition, which can affect the course of anemia. We hypothesized that the optimal hemoglobin (Hb) level varies depending on nutritional status in older patients undergoing HD and aimed to investigate the association between Hb levels and mortality according to nutritional status.

Accuracy of Current Large Language Models and The Retrieval Augmented Generation Model in Determining Dietary Principles in Chronic Kidney Disease
Gençer Bingöl F, Ağagündüz D and Bingöl MC
Large Language Models (LLMs) have emerged as powerful tools with significant potential for quickly accessing information in the nutrition and health, as in many fields. Retrieval augmented generation (RAG) has been included among artificial intelligence (AI) powered chatbot structures as a framework developed to increase the accuracy and ability of LLMs. This study aimed to evaluate the accuracy of LLMs (GPT4, Gemini, and Llama) and RAG in determining dietary principles in chronic kidney disease.
Association of protein intake with discordance between cystatin C- and creatinine-based eGFR in community-dwelling Japanese adults
Kabasawa K, Takachi R, Hosojima M, Komata T, Nakamura K, Sawada N, Tsugane S, Ito Y, Tanaka J, Narita I and Matsushita K
Recent studies have reported the prognostic implications of the discordance between creatinine-based and cystatin C-based estimated glomerular filtration rates (eGFR and eGFR, respectively); however, the associations of protein intake with the eGFR discordance have not been investigated. The present study investigated whether protein intake was associated with the discordance between eGFR and eGFR.

Comparison between Global Leadership Initiative on Malnutrition criteria and protein-energy wasting in patients with kidney failure undergoing peritoneal dialysis
Leal-Escobar G, Biruete A, Cano-Escobar KB, Madero M and Osuna-Padilla IA
Protein-energy wasting (PEW) is the chronic kidney disease (CKD)-specific diagnosis encompassing malnutrition. PEW is associated with adverse outcomes, including those receiving peritoneal dialysis (PD). Identifying PEW requires accurate methods to improve diagnosis. The Global Leadership Initiative on Malnutrition (GLIM) criteria is focused on validating a global consensus for malnutrition diagnosis in adults in clinical settings. While the GLIM criteria has been extensively studied in other clinical populations, there is limited evidence about the agreement with PEW in the PD setting. The aim of this study was to assess the agreement, accuracy, sensitivity, and specificity of GLIM criteria in comparison to the malnutrition inflammation score (MIS), a widely used tool to diagnose PEW in patients on dialysis.
Combination of clinical frailty score and myostatin concentrations as mortality predictor in hemodialysis patients
Cornet S, Quinonez K, Warling X, Jouret F, Lanot A, Bruyère O, Cavalier E and Delanaye P
Frailty is common among hemodialysis (HD) patients. Its assessment is usually based on clinical criteria. In the present work, we evaluated the interest of combining clinical frailty score and biomarkers to predict mortality of chronic HD patients. Four biomarkers were assessed: myostatin, insulin-like growth factor-1 (IGF-1), dehydroepiandrosterone sulfate (DHEA-S) and serum creatinine-to-cystastin C ratio (SCr/SCys).
Effects of Ketoanalogue Supplements on Patients Receiving Continuous Ambulatory Peritoneal Dialysis: A Multicenter, Randomized, Double-Blinded, Placebo-Controlled Study
Chen S, Fan L, Qiu Y, Chen N, Chen J, Liu Z, Xiong F, Han Q, Mao H, Lin J, Chen W and Yu X
Evidence of the effects of ketoanalogue supplements on residual kidney function (RKF) in patients undergoing continuous ambulatory peritoneal dialysis (CAPD) is limited. This study aimed to evaluate the efficacy and safety of ketoanalogues in preserving RKF in CAPD patients.
Effects of Nutritional Supplementation Combined With Exercise Training on Frailty, Physical Function, and Quality of Life in Chronic Kidney Disease: A Systematic Review and Meta-Analysis
Zhang F, Wang H, Bai Y, Huang L and Zhang H
This review evaluates the effectiveness of nutritional supplementation combined with exercise training on frailty characteristics, physical function, and health-related quality of life in patients with chronic kidney disease (CKD). A systematic search of PubMed, Embase, Web of Science, and Scopus was conducted, identifying 7 articles (9 trials, 324 patients). Meta-analysis showed that combined interventions improved frailty characteristics, such as walking speed (mean difference: 0.09 m/s, 95% confidence interval (CI): 0.02 to 0.16) and physical functioning, including cardiorespiratory fitness (standardized mean difference: 0.56, 95% CI: 0.20 to 0.93) and lower extremity mobility (Timed Up and Go test: -1.11 s, 95% CI: -1.79 to -0.43). However, effects on body weight, fatigue, and health-related quality of life remain uncertain. Due to study heterogeneity and small sample sizes, findings should be interpreted cautiously. Larger, long-term studies are needed to confirm these results and explore additional health outcomes.
"Higher renal net acid, but not higher phosphate excretion during growth associates with lower adult circulating uromodulin"
Derakhshandeh-Rishehri SM, Franco LP, Kalhoff H, Wudy SA and Remer T
Uromodulin is the most abundant urinary protein in healthy subjects which under physiological conditions protects against kidney stone formation. Acid-base imbalances, especially states with acidic urine, increase the risk for uric acid and oxalate stones, but lower it for phosphate-containing stones. Whether habitual high acid loads and high dietary phosphorus intake (P-In) themselves may influence plasma uromodulin concentrations in the long-term is not known.

Hypomagnesemia is a risk factor for acute kidney injury in patients admitted with ST-segment elevation myocardial infarction: A retrospective observational study
Jin Y, Lin Q, Wang D, Gong M, Huang W, Shan P and Liang D
Acute kidney injury (AKI) is prevalent in patients hospitalized with ST-segment elevation myocardial infarction (STEMI) and is correlated with worse cardiovascular outcomes. Hypomagnesemia has been found to be associated with an elevated risk of AKI in various patient populations. Nonetheless, the relationship between hypomagnesemia and AKI incidence in patients with STEMI has not been fully elucidated. The study aims to investigate the association between admission serum magnesium levels and the development of AKI in patients with STEMI.
A Comparison Between Severity-Dependent Protocol and Fixed-Dose Regimen of Oral Vitamin D Supplementation on Correction of Hypovitaminosis D Among Dialysis Patients
Jiampochaman S, Chuengsaman P, Kanjanabuch T, Susantitaphong P, Sriudom K, Katesomboon S, Metta K, Eiam-Ong S and Kittiskulnam P
Low vitamin D status is associated with either low muscle mass or impaired muscle function in dialysis patients. However, there is no consensus on how best to correct hypovitaminosis D, defined as serum 25-hydroxyvitamin D level <30 ng/mL, in patients with end-stage kidney disease (ESKD). This study investigated the effect of different vitamin D supplementation regimens on sarcopenia outcomes in dialysis patients.

Wang M, Chen Z, Yu T, You L, Peng Y, Chen H, Zhang P, Shi Z, Fang X, Jia L, Xia Z, Ji C, Tang H and Gao C
Skeletal muscle loss and abnormal fat distribution are predictors of poor clinical outcomes in adults with chronic kidney disease (CKD). However, the relationship between body composition (muscle mass and adipose tissue) and prognosis in children with CKD has not been well elucidated.
