Background: Chronic Kidney Disease-associated Pruritus (CKD-aP) is a frequent, debilitating, and often underestimated symptom in clinical practice, with significant impacts on quality of life, sleep, mental health, and therapeutic adherence. This study aimed to develop a structured, person-centered nursing care overview for the management of CKD-aP. Methods: A comprehensive narrative review of the recent scientific literature on CKD-aP was conducted, adapting the conceptual domains of the European Specialist Nurses Organisation (ESNO) Common Training Framework (CTF) to nephrology nursing practice. The theoretical model guiding the work was Virginia Henderson’s paradigm, selected for its consistency with care models focused on promoting independence and meeting fundamental human needs. The study would answer the main research question “Which nursing evidence, tools, and strategies can support integrated, patient-centered management of CKD-aP?”. Results: A structured nursing care process was developed, articulated in sequential phases (assessment, problem definition, planning, intervention, and re-evaluation), visually represented in an operational flowchart and supported by validated clinical tools. The model emphasizes the nurse’s role in the multidimensional management of the symptom, incorporating educational, relational, therapeutic, and coordination-focused interventions. Conclusions: This proposal contributes to nephrology nursing practice by providing a theoretical and practical framework to standardize the management of CKD-aP. It promotes a holistic, evidence-based approach tailored to individual care needs, establishing a foundation for future clinical, educational, and research developments. Full article

Accurate dry weight assessment is crucial for hemodialysis (HD) fluid management, yet traditional clinical methods often lack precision. A significant scientific gap exists in the availability of a standardized multimodal framework for integrating objective tools, leaving clinicians without clear guidance on combining results from multiple devices. To address this gap, this narrative review provides a qualitative clinical synthesis of bioimpedance spectroscopy (BIS), lung ultrasound (LUS), and inferior vena cava diameter (IVCD). A structured literature search was conducted across PubMed, Scopus, and CINAHL for English-language studies published between 2012 and 2024. Studies focusing on dry weight assessment using these tools in adult HD patients were included, and findings from 22 core studies were synthesized narratively. BIS and LUS are valuable tools for identifying fluid overload. BIS assesses systemic fluid distribution across compartments, whereas LUS allows non-invasive detection of extravascular lung water. In contrast, IVCD primarily reflects intravascular volume status. While the integrated use of these tools shows potential clinical utility, individual methods, particularly IVCD, require further validation owing to interpatient variability. A multimodal approach that integrates these objective methods with clinical judgment offers a comprehensive evaluation of dry weight. Integrating these assessment strategies may improve outcomes and decision-making in nephrology care. Full article

Background: Artificial intelligence in nephrology has largely focused on predictive models for outcomes such as acute kidney injury (AKI), chronic kidney disease (CKD) progression, and transplant complications. Although these models demonstrate technical performance, their real-world clinical impact has remained limited because prediction alone rarely translates into coordinated clinical action. Clinical artificial intelligence agents represent workflow-native systems that operate in real time, interact bidirectionally with clinical environments, adapt to evolving patient and workflow states, and support coordinated clinical action rather than generating isolated predictions. This review proposes clinical artificial intelligence agents as a new paradigm for integrating artificial intelligence directly into nephrology workflows. Methods: We conducted a narrative synthesis of emerging literature on artificial intelligence systems, agentic artificial intelligence architectures, clinical decision support, and digital health infrastructures relevant to kidney care. Drawing from interdisciplinary sources in medicine, health informatics, and artificial intelligence research, we developed a conceptual framework describing the architecture, governance requirements, and evaluation principles of clinical artificial intelligence agents in nephrology. Results: Clinical artificial intelligence agents represent workflow-integrated systems capable of continuously perceiving patient data, reasoning under clinical constraints, planning tasks, and supporting coordinated clinical actions over time. We describe a layered architecture consisting of perception, cognition, planning and control, action, and learning components. Potential applications span the nephrology care continuum, including CKD management, AKI monitoring, dialysis and continuous renal replacement therapy (CRRT) optimization, kidney transplantation care coordination, glomerulonephritis management, and supervised patient-facing systems. Conclusions: Clinical artificial intelligence agents shift the role of artificial intelligence from isolated prediction toward longitudinal clinical orchestration. Future evaluation should prioritize workflow integration, time-to-action, clinician oversight, safety, and patient-centered outcomes rather than relying solely on traditional model performance metrics. This roadmap provides a conceptual foundation for the responsible development and clinical integration of agentic artificial intelligence systems in nephrology. Full article

Background/Objectives: Cardiac and renal dysfunction frequently coexist and interact bidirectionally, constituting cardiorenal syndrome (CRS). In aging societies, this overlap is increasingly conceptualized within cardiovascular–kidney–metabolic (CKM) syndrome, in which metabolic risk factors, chronic kidney disease (CKD), and cardiovascular disease cluster and worsen prognosis. Patients with cardiorenal multimorbidity exhibit reduced exercise tolerance, physical activity, and skeletal muscle function, leading to frailty, disability, recurrent hospitalization, and reduced tolerance of disease-modifying therapies. Although exercise-based rehabilitation is central to cardiovascular care and increasingly recognized in nephrology, its role in combined cardiac and renal dysfunction remains insufficiently integrated. Methods: This narrative review synthesizes cardiology and nephrology evidence using a functional framework. We address (i) the epidemiology and clinical significance of cardiorenal overlap across CRS/CKM, (ii) functional phenotypes defined by inactivity, low exercise capacity, sarcopenia/frailty, and disability, (iii) rehabilitation effects on physical function and renal trajectories, including renal endpoint validity (creatinine vs. cystatin C), and (iv) prognostic implications and evidence gaps. Results: Evidence from heart failure trials demonstrates that exercise-based cardiac rehabilitation improves health-related quality of life and reduces hospital admissions. In CKD, systematic reviews support exercise benefits for physical function and cardiometabolic risk. Conclusions: Although evidence remains limited, data support rehabilitation as a biologically plausible, function-centered therapeutic strategy. Full article

Background: Chronic kidney disease (CKD) and end-stage renal disease (ESRD) represent a growing global health burden, affecting nearly one in ten adults worldwide. CKD is associated with high morbidity, premature mortality, reduced quality of life and enormous healthcare costs, and is primarily driven by dialysis and kidney transplantation. The silent and progressive nature of CKD means that most patients are diagnosed late, when irreversible damage has already occurred and costly kidney replacement therapies (KRT) become necessary. Dialysis services are resource-intensive, requiring significant infrastructure, specialized staff, and consumables, which makes them especially challenging to sustain in low- and middle-income countries. Traditional models of nephrology, care center-based dialysis and fragmented follow-up are increasingly inadequate in meeting the demands of a rising CKD population. These challenges highlight the urgent need for innovative approaches that enhance efficiency, improve patient outcomes, and expand access. Objective: This review aims to analyze the current landscape of information and communication technology (ICT) applications in nephrology and to evaluate how digital innovations are reconfiguring kidney therapy. Specifically, it seeks to identify the major ICT tools that are currently in use, assess their clinical and operational impact, and discuss their role in creating more sustainable, patient-centered kidney care models. This study reviews and analyzes ICT tools that are reconfiguring nephrology, including remote monitoring, AI, wearables, patient engagement apps and data dashboards. Methods: Narrative and scoping review of recent innovations in nephrology, including remote patient monitoring (RPM), telehealth, artificial intelligence (AI) analytics, wearable sensors, and clinical decision support platforms. Results: ICT tools such as Sharesource, Versia, telenephrology platforms, medical assistant for Chronic Care Service (MACCS), AI-based predictive analytics, wearable devices and patient engagement apps have improved patient outcomes, adherence, and early detection of complications. Key metrics include technique survival, hospitalization rate, patient-reported outcomes, workflow efficiency, and prediction accuracy. The relevant literature describing the potential of digital health technologies, including ICT platforms, artificial intelligence tools, and remote monitoring systems, to transform nephrology care was retrieved and screened for inclusion in this narrative review. Conclusions: ICT has shifted nephrology from reactive to proactive care, enhancing accessibility, patient empowerment and clinical efficiency. Future directions include precision nephrology, fully wearable kidneys, AI integration and large language models for education and triage. Challenges include digital divide, regulatory heterogeneity, cost and the need for long-term evidence. Full article

Psychological comorbidity is increasingly recognized as a critical factor influencing outcomes in chronic illness management, particularly in patients with end-stage renal disease (ESRD). The present study examines the psychological burden associated with long-term hemodialysis in patients with ESRD, focusing on emotional distress and maladaptive personality traits. Specifically, it explores group differences between hemodialysis patients and matched healthy controls in levels of stress, anxiety, depression, and psychopathological tendencies, including neuroticism, paranoia, and psychopathy-related traits, as well as exploratory associations with treatment duration. A purposive sample of 60 participants (30 patients undergoing chronic hemodialysis and 30 age- and sex-matched healthy controls) was assessed using validated psychometric instruments: The Hospital Anxiety and Depression Scale, the Pichot Neuroticism and Psychopathy Questionnaire, and a 23-item stress measurement questionnaire adapted to the dialysis context. Both descriptive and inferential statistical analyses were conducted, including independent-samples t-tests and effect size calculations (Cohen’s d). Compared to healthy controls, hemodialysis patients exhibited significantly higher levels of psychological distress across multiple domains. Large between-group effect sizes were observed for depression (Cohen’s d = 1.26) and perceived stress (d = 1.51), while moderate effects were identified for anxiety (d = 0.70), neuroticism (d = 0.58), and psychopathy-related traits (d = 0.82). Exploratory analyses indicated that patients with less than 10 years of dialysis experience reported significantly higher stress levels than those with longer treatment duration, whereas differences in anxiety, depression, and personality traits by dialysis duration were not statistically significant. These findings highlight the substantial emotional burden associated with long-term hemodialysis and underscore the importance of routine psychological screening and early psychosocial interventions to support adaptation, treatment adherence, and quality of life in nephrology care.

Background: Chronic kidney disease (CKD) continues to place immense strain on health systems globally, with nurses at the centre of care delivery physically, emotionally, and relationally. In dialysis units, nurses form long-term therapeutic relationships with patients who depend on life-sustaining treatment several times a week. Objective: This study explored the lived experiences of professional nurses caring for patients with CKD in a dialysis unit, using Watson’s Theory of Human Caring as a guiding framework. Methods: A qualitative, exploratory, descriptive design was employed. Data were collected through in-depth face-to-face interviews with twelve professional nurses and analyzed using thematic analysis. Trustworthiness was ensured through credibility, dependability, confirmability, transferability, and authenticity. Ethical approval and informed consent were obtained. Results: Three themes emerged: (1) emotional and professional experiences, (2) systemic resource constraints, and (3) recommendations for practice improvement. These findings highlight the tension between caring ideals and systemic limitations. Conclusions: The study concludes that dialysis nursing is profoundly meaningful yet emotionally demanding. Strengthened emotional support, improved leadership visibility, consistent resource allocation, and enhanced nephrology nursing education are critical to sustaining compassionate care. The findings offer important insights for policy, workforce development, and quality improvement efforts in CKD care. Full article

Background/Objectives: Nutritional management is central to the care of patients with end-stage renal disease (ESRD), yet malnutrition often remains under-recognized due to gaps in nursing knowledge and competencies. This study aimed to develop and validate the Nursing Education and Competencies in Nutrition for Patients with CKD in ESRD (NECN-ESRD) questionnaire, designed to assess nephrology nurses’ competencies, attitudes, and practices in nutritional care. Methods: A methodological and cross-sectional design was adopted, following the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) recommendations for instrument development. The process comprised five phases: construct definition and item generation, expert consultation and revision, quantitative content validity analysis, pilot testing, and psychometric testing. Data were collected between August and September 2025 from 405 nephrology nurses across Italy. Exploratory Factor Analyses (EFAs) and Confirmatory Factor Analyses (CFAs) were conducted on split samples (60/40), and key psychometric properties were evaluated. Results: EFA identified a four-factor structure—Recommendations, Attitudes, Practice, and Advanced Competencies—which was confirmed through CFA with good fit indices [Comparative Fit Index (CFI) = 0.995, Tucker–Lewis Index (TLI) = 0.994, Root Mean Square Error of Approximation (RMSEA) = 0.07]. A higher-order model further improved fit (CFI = 0.994, RMSEA = 0.029), explaining 68.2% of variance. Internal consistency was excellent (ω = 0.89–0.96), test–retest reliability showed perfect agreement [Intraclass Correlation Coefficient (ICC) = 1.00], and invariance testing supported equivalence across educational and experience levels. Conclusions: The NECN-ESRD demonstrated strong validity, reliability, and stability, providing a robust and context-specific tool to assess and enhance nurses’ competencies in nutritional care for ESRD patients. Its application can support targeted educational interventions, improve clinical practice, and contribute to enhancing the quality of nutritional care for patients with ESRD within healthcare systems.

At the beginning of life, there are no sex differences in fetal kidney growth, nephron endowment nor in the prevalence of low birth weight. In chronic kidney disease (CKD) in adults, however, significant sex- and gender-specific differences exist in diagnosis, progression, and management of CKD. In adult individuals, CKD is more prevalent in women, but CKD progression is faster in men; nevertheless, women have a higher life expectancy than men. A possible explanation for the enigmatic higher CKD prevalence in women may derive from the Brenner–Luyckx concept of hyperfiltration. Diseases that lead to hyperfiltration will lead to premature nephron loss and to a faster decline in glomerular filtration rate (GFR). This condition is predominantly seen in middle-aged men with a higher GFR, larger hypertrophied kidneys, and a higher prevalence of arterial hypertension, diabetes mellitus, smoking, and hypercholesterolemia compared to women. Thus, a high GFR may not be a good sign if it reflects hyperfiltration. Any GFR must be interpreted against the comorbidities of an individual. An individual may end up with a realistic GFR far below normal once hyperfiltration is stopped, for example, by a Sodium Glucose-Linked Transporter 2 (SGLT2) inhibitor. With regard to the management of CKD, women with CKD receive poorer healthcare compared to men with CKD. Women less frequently receive a CKD diagnosis, are less frequently referred to nephrology for co-management, less frequently undergo eGFR and albuminuria assessments, and are less likely to receive guideline-recommended treatments for CKD, such as angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers, and statins. Cardiovascular risk factors are less rigorously controlled in women with CKD compared to men with CKD. The causes for the poorer CKD care among women are to be found in gender rather than in sex. It is crucial to integrate assessments of sex and gender into both clinical routines and scientific reports. All studies should incorporate sex- and gender-specific analyses, and the evaluation of pre- and postmenopausal women should be conducted separately. The utilization of Gender Scores can help identify the impact of cultural, societal, and psychological factors on observed gender differences in ambulatory healthcare for those with CKD. Guidelines need to be sensitive to gender and emphasize the existing knowledge gaps regarding sex and gender differences in CKD healthcare. Urgent attention is required to substantially improve and ensure equitable healthcare for CKD across sexes and genders. Full article

Background: Managing end-of-life decisions in canine chronic kidney disease (CKD) remains one of the most significant challenges in veterinary nephrology, requiring a delicate balance between clinical data and ethical considerations. Objective: This study introduces a novel decision-making algorithm designed to guide clinicians and owners through the complexities of end-of-life care, focusing on the assessment of Quality of Life (QoL) and disease progression. Methods: The tool integrates IRIS staging with a multi-parameter QoL checklist, categorizing patients into three distinct clinical pathways: Tier A (Active Palliative Care), Tier B (Intensive Monitoring/Ambiguous Zone), and Tier C (Compassionate Euthanasia). Results and Discussion: The algorithm defines Tier A as a proactive palliative pathway grounded in systematic clinical evaluation and continuous QoL assessment, aimed at preserving patient comfort and dignity. Across all tiers, QoL functions as a dynamic and central parameter, guiding transitions between clinical pathways in conjunction with objective indicators of disease progression. Tier C delineates the threshold of therapeutic futility, where declining QoL and biological resilience converge, and euthanasia is framed as an ethically appropriate option to prevent refractory suffering. Conclusions: By providing methodological transparency and clear clinical thresholds, this tool facilitates communication between veterinarians and owners. It ensures that palliation is approached with high-standard medical rigor while safeguarding the animal’s dignity when biological resilience is exhausted. Full article

Background: Adults on maintenance hemodialysis experience multiple physical and psychological symptoms that can affect confidence in self-management and perception of care received from healthcare providers. Understanding the interplay between symptom burden, self-management self-efficacy, and perceptions about care received is essential to inform patient-centered nephrology nursing. Aim: This cross-sectional study aimed to describe dialysis symptom burden, self-efficacy to manage chronic disease, and satisfaction with nursing care, and to examine associations among these variables in adults undergoing maintenance hemodialysis in Oman. Methods: A cross-sectional study using consecutive sampling was conducted among 232 adults on maintenance hemodialysis at two dialysis units in Muscat, Oman. Data were collected using the Dialysis Symptom Index, the nursing care satisfaction questionnaire, and the self-efficacy scale. Descriptive, correlation, and multivariable linear regression analysis were used to summarize the findings. Results: The mean age was 55.9 years and the most common comorbidities were diabetes (58.2%) and hypertension (74.1%). Symptom burden was substantial, with over half reporting muscle soreness, anxiety, sleep disturbance, dry mouth, pruritus, appetite loss, and dyspnea, although severity was generally mild–moderate (1.1–1.6/4). Satisfaction with nursing care was high (90.2%), while self-efficacy was moderate (mean 30.52/44). Patient satisfaction correlated positively with self-efficacy (r = 0.25, p < 0.001), but not with symptom burden (r = 0.08, p = 0.24); Self-efficacy showed a small positive correlation with dialysis symptom burden (r = 0.14, p = 0.03), suggesting that patients who were more aware of and reported more symptoms also perceived themselves as more actively engaged in managing their illness. In multivariable analysis, higher satisfaction and more favorable laboratory indicators independently predicted higher self-efficacy. Conclusions: Adults on hemodialysis reported high satisfaction with nursing care but continued to experience multiple physical and psychological symptoms and had only moderate self-efficacy to manage their condition. There is a need to integrate structured symptom assessment and targeted, nurse-led self-management support intervention into routine dialysis care to reduce symptom burden and enhance patients’ confidence in managing their illness.

Acute kidney injury (AKI) is a systemic syndrome capable of inducing remote organ dysfunction. Kidney–lung crosstalk is a form of interorgan communication in acute nephrology, with the heart acting as a pivotal intermediary. Emerging evidence supports the involvement of a gut–lung–kidney axis. Complement activation in these multiorgan crosstalk has emerged as a central amplifier of multiorgan damage. We reviewed the literature on kidney–lung interactions and complement activation in AKI through a bibliographic search of PubMed, Scopus, and Web of Science. Most available data derive from experimental studies or intensive care unit (ICU) populations, often reported in reviews. We further report our real-world experience in a non-ICU nephrology setting, including 186 consecutive patients with AKI. Pulmonary involvement was present at hospital admission in 118 patients (63%). AKI stage 1 was observed in 20/118 patients (17%) with pulmonary involvement compared with 18/68 patients (27%) without pulmonary involvement (p < 0.001). In conclusion, AKI should be regarded as a systemic disease from its earliest stages. Kidney–lung interactions are clinically relevant even in mild AKI and outside critical care settings, underscoring the need for integrated organ assessment in routine nephrology practice. This review integrates complement activation as a central amplifier of kidney–lung crosstalk and multiorgan dysfunction, bridging experimental evidence with real-world observations from a non-critical care AKI population. By focusing on early AKI stages and the timing of pulmonary involvement, we highlight AKI as an active driver of systemic organ interactions rather than a late consequence of critical illness.

Primary hyperoxaluria type 1 (PH1) is a rare autosomal recessive disorder that causes progressive renal failure, nephrolithiasis, and nephrocalcinosis in children. It is characterized by hepatic overproduction of oxalate. Conventional management, which involves combined liver–kidney transplantation, vitamin B6 supplementation, and intense hydration, does not address the underlying metabolic defect for most patients and it generally provides only supportive care. The first approved disease-modifying treatment for pediatric PH1 is Lumasiran, a small interfering RNA (siRNA) therapeutic. By specifically inhibiting the hepatic glycolate oxidase mRNA, Lumasiran lowers the production of oxalate at its origin. Along with fewer kidney stone events and stabilization of nephrocalcinosis, clinical trials (ILLUMINATE-A/B/C) showed significant decreases in urinary oxalate excretion. The most frequently reported adverse event is mild injection-site reactions, which are generally well tolerated. The molecular mechanism, pharmacokinetics, and clinical effectiveness of Lumasiran in children with PH1 are compiled in this review. We go over possible long-term safety concerns, the impact of early intervention on renal outcomes, and the function of siRNA therapies in pediatric precision medicine. Furthermore, we highlight Lumasiran’s importance as a model for targeted treatment in uncommon pediatric kidney diseases by considering it in the larger context of RNAi-based therapies. A paradigm shift in pediatric nephrology is signaled by Lumasiran, which changes the therapeutic approach from supportive care to precision, targeted medicine. Further research and empirical data will clarify its long-term advantages, the best ways to treat it, and the possible use of siRNA technologies for other genetic renal disorders. Full article

Background/Objectives: Chronic kidney disease is more prevalent among women, and there are significant disparities in the management of female patients. Our study aimed to assess the clinical experience and educational needs of physicians in the treatment of reproductive and sex and gender-related health problems in patients with CKD. Methods: The three-part survey was distributed among nephrologists and other internal medicine specialists in Poland, both online and in paper form. Results: A total of 116 physicians participated in the survey, including 81 nephrologists. Most respondents (64.7%) were female and practiced in multispecialty hospitals (72.4%). While 97.4% managed patients with CKD, only 37.9% reported caring for pregnant women. Experience in sex-specific and pregnancy-related issues was limited—56.9% reported low or minimal experience in managing CKD during pregnancy. Residency training lacked coverage of crucial topics, with 66.2% reporting limited teaching on sex-related CKD progression. Over 90% supported integrating reproductive planning and interdisciplinary care into nephrology, favoring guidelines, conferences, and webinars for education. Conclusions: Our study has highlighted a critical discrepancy between the importance of sex-specific and reproductive health considerations in the management of CKD and the current level of clinical experience among Polish doctors.

Background/Objectives: CKD affects over 10% of adults and is often silent, delaying diagnosis. Opportunistic primary care screening supported by clinical decision support systems (CDSSs) may improve detection with minimal burden. We evaluated the feasibility, diagnostic yield, clinical actions, and reagent costs of a CDSS-enabled, albuminuria-first program using eGFR. Methods: This one-year cross-sectional intervention screened all patients receiving routine laboratory tests at a primary care center using a CDSS integrating prior labs, medical records, and guideline rules. Eligibility required patients age 60–85 (Group 1) or 18–59 with hypertension, diabetes, or cardiovascular disease (Group 2). Eligible patients received urine albumin and eGFR testing with standard phlebotomy; abnormal findings triggered confirmatory tests. Outcomes were diagnostic yield, KDIGO risk stratification, referral patterns, and reagent costs. The CDSS surfaced prompts and pre-populated orders in the laboratory interface. Results: Of 7722 targets, 1892 (24.5%) were flagged (34.2% of Group 2, 7.9% of Group 1), and 1774 (93.8%) completed screening. We identified 104 new CKD cases (5.9%): 75% KDIGO moderate risk, 19% high, and 6% very high. Twenty patients (1.1%) met criteria for nephrology referral. Guideline-directed therapy was started or optimized in 90%, and 62.5% received a new CKD diagnosis code. Reagent costs averaged EUR 0.51 per person screened and EUR 11.14 per CKD case detected. Most cases were early-stage and manageable in primary care. Conclusions: CDSS-enabled opportunistic screening in primary care is feasible, acceptable, and low-cost. It identifies previously unrecognized CKD at modest expense, enabling early interventions that may slow progression and reduce cardiovascular events. Scaling with follow-up should assess long-term outcomes. Full article
