Pediatric kidney disease has a relatively lower prevalence than do other pediatric conditions and has a notably different etiology from kidney diseases observed in adults. Furthermore, the pediatric population is unique in that they experience ongoing growth and development, distinguishing them from adult patients. Consequently, pediatric patients with kidney disease require more specialized and meticulous nutritional management than do adults. To address this need and promote optimal dietary practices for pediatric patients with kidney disease, pediatric nephrologists from the Korean Society of Pediatric Nephrology and nutritionists from the Korean Society of Clinical Nutrition have collaborated to establish nutritional guidelines specifically tailored to Korean dietary patterns. These guidelines offer detailed, nutrient-specific recommendations covering energy, protein, calcium, phosphorus, and potassium consumption while providing practical, culturally relevant guidance intended to support both pediatric patients and their caregivers.

Purpose: To evaluate patient‐reported experiences of 3 primary treatments for localized or locally advanced prostate cancer—radical prostatectomy (RP), radiation therapy (RT), and active surveillance (AS)—based on cross‐sectional data from a prospective registry, and to explore how these findings can inform a structured shared decision making (SDM) framework. Materials and Methods: Men with clinical stage cT3aN0M0 or lower were enrolled. Those who underwent RP or RT were surveyed 6–24 months posttreatment; men on AS had 6–60 months of follow‐up. All participants completed the EORTC QLQ‐PR25 (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire - Prostate Cancer Module), capturing urinary, bowel, hormonal, and sexual function. The Kruskal‐Wallis test evaluated group differences, with significance set at p<0.05. Results: Among 542 patients, 435 underwent RP, 73 received RT (43% with androgen deprivation therapy), and 34 were on AS. RP patients reported higher rates of urinary incontinence and sexual dysfunction, whereas RT patients had more severe urinary irritative and bowel symptoms. AS generally preserved baseline sexual function but still involved some urinary complaints and anxiety regarding disease progression. These findings underscore the distinct trade‐offs among the 3 management strategies, emphasizing the importance of individualized SDM that accounts for functional priorities and patient values. Conclusion Each treatment modality poses unique impacts on quality of life. Incorporating these patient‐reported data into SDM discussions can improve alignment between clinical recommendations and patient preferences, potentially reducing decisional regret and enhancing long‐term outcomes.

The nutrient composition of feed plays a crucial role in regulating gene expression in animals,thereby affecting growth, metabolism, and immune functions. In poultry, the optimized use offeed additives such as crude protein and phytase can enhance nutrient absorption, improvefeed efficiency, and reduce environmental waste. In this study, we investigated the transcriptomic changes in the blood of forty-eight one-week-old broiler chickens fed diets differing in crude protein and phytase content. Using RNA sequencing and bioinformatic analysis, a total of 44 differentially expressed genes were identified in response to dietary variation. These genes were primarily involved in immune response, regulation of cell morphology, glycolytic process, and glycerolipid metabolism. Functional enrichment analysis revealed significant associations with cytokine–cytokine receptor interaction pathways, which regulate lipid metabolism, cellular proliferation, differentiation, and inflammatory responses. Moreover, decreased levels of crude protein and phytase were linked to alterations in protein autophosphorylation, amino acid biosynthesis, and energy metabolism pathways. These findings indicate that dietary modulation of crude protein and phytase levels can significantly influence metabolic and immune regulatory mechanisms in early-stage broilers. The appropriate feeding of feed additives (such as crude protein and phytase) not only improves nutritional deficiencies and feed efficiency issues in livestock, but also contributes to sustainable meat production, includ-ing the reduction of nitrogen and ammonia emissions, thereby supporting environmentallyresponsible poultry production.

Background: Procalcitonin (PCT) is a crucial biomarker for diagnosing sepsis and managing antibiotic therapy. This study evaluated the analytical performance and comparability of the Access PCT and Elecsys BRAHMS PCT assays. Methods: The precision, detection capability, linearity, and reference range of both assays were assessed. A comparative analysis included 182 patient samples categorized into four risk groups to compare the results between Access PCT and Elecsys BRAHMS PCT assays. Results: The Access PCT assay demonstrated precision within the manufacturer’s threshold, and its detection capabilities were verified. This assay exhibited excellent linearity and appropriate reference intervals. Comparative analysis indicated that the Access PCT assay reported higher overall PCT levels than the Elecsys BRAHMS assay, with high agreement between the assays (κ=0.941). However, the biases varied across different PCT concentration intervals. Conclusions Both the Access PCT and Elecsys BRAHMS PCT assays performed robustly with notable concordance but varying biases at different concentration intervals. The observed biases require careful consideration in clinical decision-making, especially when adopting novel assay systems. Standardizing the calibration across different platforms is recommended to improve assay comparability.

The Weight Management Health Note application, developed by the Korean Society for the Study of Obesity (KSSO), was designed to assist individuals in weight management and enhance overall well-being. The Committee of IT-Convergence Treatment of Metabolic Syndrome of the KSSO designed this application. Committee members reviewed and supervised the application’s underlying driving algorithms and scientific rationale. A healthcare-specific application developer subsequently finalized the application. This application encompasses a myriad of features, including a comprehensive food diary, an exercise tracker, and tailor-made lifestyle recommendations aligned with individual needs and aspirations. Moreover, it facilitates connections within a community of like-minded individuals endeavoring to manage their weight, fostering mutual support and motivation. Importantly, the application is rich in evidence-based health content curated by the KSSO, ensuring users access accurate information for effective obesity management. Looking ahead, the KSSO is committed to orchestrating diverse academic research endeavors linked to this application and refining its functionalities through continuous feedback from users. The KSSO aspires for this application to serve as a valuable resource for individuals striving to manage their health and enhance their quality of life.
