[Nephrological nutritional office: a transversal organization model and access flowchart].

The nutritional aspect has a critical relevance in the educational and care path of nephropathic patients. The Nephrology-Dietology synergy in the Hospital is conditioned by various factors, such as the difficulty for Dietology to provide capillary and personalized follow-up to nephropathic patients. Hence the experience of a transversal II level nephrological clinic, dedicated to nutritional aspects throughout the path of nephropathic patients, from the earliest stages of kidney disease to replacement treatment. The access flowchart provides a nephrological indication: from chronic kidney disease (CKD), kidney stones, immunopathology, hemodialysis, peritoneal dialysis, and transplantation clinics, from the nephrological department, patients are selected for evaluation. The clinic is conducted by an expert nephrologist and trained dietitians, and is divided into different settings: educational meetings in small groups (patients and caregivers); simultaneous dietary and nephrological visits to advanced CKD; nutritional-nephrological visits on specific problems: from metabolic screening of kidney stones to action on the intestinal microbiota in immunological pathologies, to the application of the ketogenic diet in obesity, metabolic syndrome, diabetes, and early kidney damage, to onconephrology. Submission to further dietological assessment is limited to critical and selected cases. The synergistic model between nephrology and dietetics offers clinical and organizational advantages: guarantees a capillary follow-up, reduces the number of hospital accesses, thus enhancing compliance and clinical outcomes, optimizes available resources, and overcomes the critical issues of a complex hospital with the advantage of the always profitable multidisciplinarity.

[Artificial intelligence: a new journey in nephrology].

The rapid development of artificial intelligence (AI) technology, especially the progress in deep learning methods and computing power of hardware, has greatly promoted the application of AI in the field of biomedicine and nephrology. AI can predict the occurrence of acute kidney injury, identify chronic kidney disease, and assist in the analysis of kidney disease pathology, prognosis prediction and decision-making. The application of AI in the field of nephrology depends on the coordinated development of nephrology and artificial intelligence, and requires close interdisciplinary cooperation between multiple disciplines. This article describes the application and research progress of AI in nephrology and provides insights for future directions.

Psychosocial supports within pediatric nephrology practices: A pediatric nephrology research consortium survey.

BACKGROUND: The landscape of available psychosocial services within pediatric nephrology care is poorly characterized. However, the effects of kidney disease on emotional health and health-related quality of life are well documented, as is the impact of social determinants of health on kidney disease outcomes. The objectives of this study were to assess pediatric nephrologists' perceptions of available psychosocial services and to elucidate inequities in access to psychosocial care. METHODS: A web-based survey was distributed to members of the Pediatric Nephrology Research Consortium (PNRC). Quantitative analyses were performed. RESULTS: We received responses from 49 of the 90 PNRC centers. With regards to dedicated services, social work was most commonly available (45.5-100%), followed by pediatric psychology (0-57.1%) and neuropsychology (0-14.3%), with no centers having embedded psychiatry. Availability of psychosocial providers was positively associated with nephrology division size, such that as center size increased, access to various psychosocial providers increased. Notably, the majority of respondents indicated that perceived need for psychosocial support exceeds that which is currently available, even at centers with higher levels of current support. CONCLUSIONS: Within the US, there is wide variability in the availability of psychosocial services within pediatric nephrology centers despite a well-documented necessity for the provision of holistic care. Much work remains to better understand the variation in funding for psychosocial services and in utilization of psychosocial professionals in the pediatric nephrology clinic, and to inform key best practices for addressing the psychosocial needs of patients with kidney disease.

Antihypertensive Medications Use among Chronic Hemodialysis Patients Visiting the Outpatient Department of Nephrology of a Tertiary Care Centre: A Descriptive Cross-sectional Study.

Introduction: Anti-hypertensive medications are prescribed for the management of high blood pressure which is the leading cause of mortality in chronic hemodialysis patients. The objective of our study was to find out the prevalence of anti-hypertensive medication use among chronic hemodialysis patients visiting the outpatient Department of Nephrology of a tertiary care centre. Methods: This was a descriptive cross-sectional study conducted among chronic hemodialysis patients visiting the Department of Nephrology of a tertiary care centre from 2 April 2022 to 30 September 2022.

Pyonephrosis among Patients with Pyelonephritis Admitted in Department of Nephrology and Urology of a Tertiary Care Centre: A Descriptive Cross-sectional Study.

Introduction: Pyonephrosis is a severe complication of pyelonephritis leading to rapid progression to sepsis and loss of renal function resulting in nephrectomy. Early identification of pyonephrosis based on clinical or radiological characteristics amongst pyelonephritis is paramount. This study aimed to determine the prevalence of pyonephrosis among patients with pyelonephritis admitted to the Department of Nephrology and Urology of a tertiary care centre. Methods: This descriptive cross-sectional study was done in a tertiary care centre among patients with pyelonephritis from 1 July 2016 to 31 Jan 2021. Ethical approval was obtained from Institution Ethics Committee (Reference number: IEC/56/21). The available clinical, demographic and laboratory parameters were recorded from the hospital records in a predesigned proforma. A convenience sampling method was used. Point estimate and 95% Confidence Interval were calculated. Results: Among 550 pyelonephritis patients, the prevalence of pyonephrosis was 60 (10.9%) (8.3-13.5, 95% Confidence Interval). The mean age was 54.62±12.14 years, and 41 (68.33%) were males. The most common clinical symptom was flank pain with or without fever in 46 (76.66%) patients. Escherichia coli was the most common offending organism in 20 (33.33%). Ultrasonography showed classical echogenic debris with floaters and internal echoes in 44 (73.33%) patients. Double J stenting was successfully done in 44 (73.33%) patients. Percutaneous nephrostomy was done in the remaining 16 (26.66%) patients. Conclusions: The prevalence of pyonephrosis in pyelonephritis is similar to previous studies done in similar settings. Keywords: pyelonephritis; pyonephrosis; kidneys.

Subclinical Hypothyroidism among Chronic Kidney Disease Patients Admitted to Nephrology Department of a Tertiary Care Centre: A Descriptive Cross-sectional Study.

Introduction: Chronic kidney disease is a condition, which worsens the quality of life in many ways including thyroid disorder in many cases. The aim of the study was to find out the prevalence of subclinical hypothyroidism among chronic kidney disease patients admitted to the Nephrology Department of a tertiary care centre. Methods: A descriptive cross-sectional study was carried out on the patients diagnosed with chronic kidney disease at a tertiary care hospital from 15 May 2022 to 10 October 2022 after getting ethical approval from the Institutional Review Committee (Reference number: 621/2022). Pre-designed proforma was used to collect demographic data like age, sex, height and weight. Blood samples of the patients were analysed for thyroid function tests (triiodothyronine, thyroxine and thyroid stimulating hormone levels) by chemiluminescence immunoassay. Convenience sampling was used. Point estimate and 95% Confidence Interval were calculated. Results: Out of 156 study participants with chronic kidney disease, subclinical hypothyroidism was present in 34 (21.79%) (15.31-28.27, 95% Confidence Interval) patients. Conclusions: The prevalence of subclinical hypothyroidism amongst chronic kidney disease patients was found to be lower than in other similar studies conducted in similar settings. Keywords: chronic kidney disease; thyroid stimulating hormone; thyroxine; triiodothyronine.

To recognize this event, we conducted an archival review of the journal dating back to the first issue. The review provided a glimpse into the care of patients with kidney disease and the history of nephrology nursing. This article focuses on the early years of the journal.

Defining myocardial infarction in trials of people receiving hemodialysis: consensus report from the SONG-HD MI Expert Working group.

Cardiovascular disease is the leading cause of death in patients receiving hemodialysis. Currently, there is no standardized definition of myocardial infarction (MI) for patients receiving hemodialysis. Through an international consensus process MI was established as the core CVD measure for this population in clinical trials. The Standardised Outcomes in Nephrology Group-Hemodialysis (SONG-HD) initiative convened a multidisciplinary, international working group to address the definition of MI in this population. On the basis of current evidence, the working group recommends using the Fourth Universal Definition of Myocardial Infarction with specific caveats with regard to the interpretation of "ischemic symptoms" and performing a baseline 12-lead electrocardiogram to facilitate interpretation of acute changes on subsequent tracings. The working group does not recommend obtaining baseline cardiac troponin values, though does recommend obtaining serial cardiac biomarkers in settings where ischemia is suspected. The application of an evidence-based uniform definition should increase the reliability and accuracy of trial results.

La «Semana del Fósforo»: implicación de la nefrología española en el control de los valores plasmáticos de fósforo / The “Phosphorus Week”: Involvement of Spanish nephrologists in the control of phosphorus blood levels

Antecedentes: El adecuado control de la fosfatemia es objeto de importante preocupación por los profesionales involucrados en el cuidado de los pacientes con enfermedad renal crónica (ERC), ya que los valores elevados de fósforo se encuentran directamente relacionados con un aumento de la mortalidad. Objetivos: Con el objetivo de conocer la percepción y la implicación que los nefrólogos españoles tienen de la necesidad de controlar el fósforo sérico, así como lograr una muestra lo más representativa posible de los valores séricos actuales, se organizó la denominada «Semana del Fósforo» (13-17 de noviembre de 2017). Métodos: Se invitó a participar en una encuesta on line a todos los socios de la Sociedad Española de Nefrología, que incluía preguntas sobre aspectos relacionados con el control del fósforo en pacientes con ERC avanzada (ERCA) (filtrado glomerular <30ml/min/1,73m2) y en las distintas modalidades de tratamiento renal sustitutivo (diálisis peritoneal [DP], hemodiálisis [HD] y trasplante renal [TR]). Resultados: Se obtuvieron 72 entradas de datos con 7.463 pacientes incluidos, de los cuales el 35,4% de ellos estaban en HD, el 34,8% eran TR, el 24,2% tenían ERCA y el 5,5% estaban en DP. El objetivo de fósforo sérico para los cuatro grupos de pacientes fue de 4,5mg/dl, con mínimas variaciones en función del área del territorio nacional. Los pacientes con mejor control de la fosfatemia fueron los pacientes con TR (el 93,3% presentaban valores de fósforo <4,5mg/dl), seguidos por los pacientes en ERCA (65,6% con fósforo <4,5mg/dl). Solo el 53,6% de los pacientes en HD y el 39,4% de los que estaban en DP cumplieron el objetivo de fósforo <4,5mg/dl. El grupo de pacientes en diálisis fue en el que más se prescribían captores de fósforo (73,5% y 75,6% en los pacientes en HD y DP, respectivamente), siendo menos frecuente en los pacientes en ERCA (39,9%) y solo el 4,5% en los TR.

Background: The adequate control of phosphorus levels is a major concern for professionals involved in the care of patients with chronic kidney disease (CKD), since high phosphorus levels are directly related to an increase in mortality. Objectives: To know the perception and involvement of Spanish nephrologists on the control of phosphorus levels, the so-called “Phosphorus Week” was organized (November 13-17, 2017). Methods: All members of the Spanish Society of Nephrology were invited to participate in an online survey, which included questions on aspects related to phosphorus control in patients with advanced CKD (aCKD) (glomerular filtration rate <30ml/min/1.73m2) and in the different modalities of renal replacement therapies (peritoneal dialysis [PD], hemodialysis [HD] and renal transplantation [KT]). Results: 72 data entries were obtained in the survey with an inclusion of 7463 patients. Of them, 35.4% were on HD, 34.8% were KT, 24.2% had aCKD and 5.5% were on PD. The serum phosphorus level target for the four groups of patients was 4.5mg/dl, with minimal variations depending on the area of the national territory. The patients with better control of phosphatemia were patients with KT (93.3% had phosphorus values <4.5mg/dl), followed by patients with aCKD (65.6% with phosphorus <4.5mg/dl). Only 53.6% of the patients on HD and 39.4% of those on PD reached the phosphorus goal <4.5mg/dl. The group of patients on dialysis was the one in whom phosphorus binders prescribed the most (73.5% and 75.6% in HD and PD, respectively), being less frequent in patients with patients with aCKD (39.9%) and only 4.5% in KT.

Admission of kidney patients to a closed staff nephrology department results in a better short-term survival.

BACKGROUND: The outcome of patients with chronic kidney disease (CKD) and acute kidney injury (AKI) is often dismal and measures to ameliorate their course are scarce. When admitted to the hospital, kidney patients are often hospitalized in general Medicine wards rather than in a specialized Nephrology department. In the current study, we compared the outcome of two cohorts of kidney patients (CKD and AKI) admitted either to general open-staff (with rotating physicians) Medicine wards or to a closed-staff (non-rotating Nephrologists) Nephrology ward. METHODS: In this population-based retrospective cohort study, we enrolled 352 CKD patients and 382 AKI patients admitted to either Nephrology or General Medicine wards. Short-term (< = 90 days) and long-term (>90 days) outcomes were recorded for survival, renal outcomes, cardiovascular outcomes, and dialysis complications. Multivariate analysis was performed using logistic regression and negative binomial regression adjusting to potential sociodemographic confounders as well as to a propensity score based on the association of all medical background variables to the admitted ward, to mitigate the potential admittance bias to each ward. RESULTS: One hundred and seventy-one CKD patients (48.6%) were admitted to the Nephrology ward and 181 (51.4%) were admitted to general Medicine wards. For AKI, 180 (47.1%) and 202 (52.9%) were admitted to Nephrology and general Medicine wards, respectively. Baseline age, comorbidities and the degree of renal dysfunction differed between the groups. Using propensity score analysis, a significantly reduced mortality rate was observed for kidney patients admitted to the Nephrology ward vs. general Medicine in short term mortality (but not long-term mortality) among both CKD patients admitted (OR = 0.28, CI = 0.14-0.58, p = 0.001), and AKI patients (or = 0.25, CI = 0.12-0.48, p< 0.001). Nephrology ward admission resulted in higher rates of renal replacement therapy (RRT), both during the first hospitalization and thereafter. CONCLUSIONS: Thus, a simple measure of admission to a specialized Nephrology department may improve kidney patient outcome, thereby potentially affecting future health care planning.
