Horizontal analysis and longitudinal cohort study of chronic renal failure correlates and cerebral small vessel disease relationship using peak width of skeletonized mean diffusivity.

Background and purpose: Peak width of skeletonized mean diffusivity (PSMD) is an MRI-based biomarker that may reflect white matter lesions (WML). PSMD is based on skeletonization of MR DTI data and histogram analysis. Both chronic renal failure (CRF) and WML may be affected by multisystemic small-vessel disorder. We aimed to explore the relationship between PSMD and estimated glomerular filtration rate (eGFR). Methods: Fifty followed-up CRF patients matched for age, sex, hypertension and smoking status were enrolled and classified into a progressive group (n = 16) and stable group (n = 34) based on eGFR levels. Longitudinal and horizontal differences of PSMD were compared between the progressive and stable groups at the initial and follow-up time points. Pearson's correlation was used for correlation of eGFR with PSMD and WML (per Fazekas scale score). ROC was used to measure the sensitivity of PSMD and WML score to changes of eGFR. Results: At the follow-up time point, PSMD of the progressive group was significantly higher than at the initial time point (p < 0.001), and PSMD of the progressive group was significantly higher than stable group (p < 0.001). PSMD and eGFR were significantly correlated. AUC curves explored that ΔPSMD (PSMD changes at the follow-up and initial time points) and follow-up PSMD was better for the classification of progressive and stable groups. Conclusion: PSMD has significant correlation with eGFR, PSMD can reveal a close relationship between WML and CRF.

Cohort profile: the PRIMETIME 1 (PRecIsion MEdicine based on kidney TIssue Molecular interrogation in diabetic nEphropathy) cohort - a longitudinal Danish nationwide study of individuals with diabetes and a performed kidney biopsy.

PURPOSE: Individuals with diabetes and chronic kidney disease are at high risk of kidney failure, cardiovascular events and premature mortality and more research is warranted to further improve the prevention and management of complications. The PRecIsion MEdicine based on kidney TIssue Molecular interrogation in diabetic nEphropathy (PRIMETIME) 1 cohort is designed to study clinical characteristics, diagnostic accuracy and prognostic markers in a population with diabetes and kidney disease classified by biopsy. PARTICIPANTS: This retrospective Danish nationwide cohort includes 2586 individuals with diabetes who have undergone a kidney biopsy between the 1980s and 2022. FINDINGS TO DATE: By combining multiple registries and medical databases, we comprehensively describe the cohort with data on demographics, socioeconomic status, lifestyle, laboratory measurements, medication use and comorbidity at the time of diagnosis of diabetes and at the time of kidney biopsy within types of kidney disease. In individuals with type 1 diabetes, 132 cases of diabetic nephropathy were identified, with 70.5% of them being men, with a median (IQR) age of 50 (41-59) years at biopsy, and a median (IQR) estimated glomerular filtration rate (eGFR) 37 (23-5X) mL/min/1.73 m2. Among individuals with type 2 diabetes and diabetic nephropathy (n=599), 76.8% were male aged 61.9 (55-99) years at biopsy and with an eGFR 40 (24-6X) mL/min/1.73 m2. FUTURE PLANS: The national population registries in Denmark provide a long follow-up period and a distinct opportunity to use superior registry data. This cohort offers a unique opportunity to study the prognostic value of findings in kidney biopsies, the impact of comorbidity and the effect of therapy at the time of kidney biopsy, with a follow-up period increasing over time with running updates.

Posterior Urethral Valves in a Healthy-Appearing Athletic Adult: A Case Report.

Posterior urethral valves (PUV) are a congenital malformation of the male urethra where the posterior opening connecting to the bladder is covered by membranous folds. Most cases are diagnosed antenatally, with postnatal cases typically diagnosed and surgically repaired within the first years of life. Delayed presentation beyond infancy is rare, with presentation into adulthood being exceedingly rare, especially in the United States. We present a case of an 18-year-old healthy-appearing athletic male who presented with delayed presentation of PUV. This patient with no significant past medical history presented to the emergency room upon referral by his primary care physician, who denoted incidental findings of elevated blood pressure and acute renal failure at his annual physical examination. This led to further investigation, including a full renal blood workup, bilateral renal ultrasound, and voiding cystourethrogram, which revealed severe bilateral hydronephrosis, cortical thinning, and diverticula of the bladder, prompting a diagnosis of PUV. The patient underwent laser valve ablation surgery, although unfortunately, the surgery will prevent symptoms from progressing but is unlikely to reverse the current stage of chronic kidney damage. Even though delayed presentation of PUV is rare, it is important to recognize that patients may have a long history of renal complaints and may have normalized and internalized their symptoms. Physicians should take detailed and holistic medical histories and create a safe, non-judgmental environment to build rapport with young adult patients, ensuring early and effective medical intervention.

Establishing an autogenous vascular access program in a Guatemalan comprehensive pediatric nephrology center.

BACKGROUND: The Guatemalan Foundation for Children with Kidney Diseases collaborated with Bridge of Life, a not-for-profit charitable organization, to establish a vascular access program. We reviewed our experience with graded surgical responsibility and structured didactic training, creating arteriovenous fistulas (AVF) for Guatemalan children. METHODS: Pediatric vascular access missions were completed from 2015 to 2023 and analyzed retrospectively. Follow-up was completed by the Guatemalan pediatric surgeons, nephrologists, and nursing staff. AVF patency and patient survival were evaluated by Kaplan-Meier life-table analysis with univariate and multivariable association between patient demographic variables by Cox proportional hazards models. RESULTS: Among a total of 153 vascular access operations, there were 139 new patient procedures, forming the study group for this review. The mean age was 13.6 years, 42.6% were female, and the mean BMI was 17.3. Radial or ulnar artery-based direct AVFs were established in 100 patients (71.9%) and ten of the 25 transposition procedures. Brachial artery inflow was required in 29 direct AVFs (20.9%). Two patients underwent femoral vein transpositions. Access-related distal ischemia was not encountered. Seven of the AVF patients later required access banding for arm edema; all had previous dialysis catheters (mean = 9, range 4-12). Primary and cumulative patency rates were 84% and 86% at 12 months and 64% and 81% at 24 months, respectively. The median follow-up was 12 months. Overall patient survival was 84% and 67% at 12 and 24 months, respectively. There were no deaths related to AVF access. CONCLUSIONS: Safe and functional AVFs were established in a teaching environment within a Guatemalan comprehensive pediatric nephrology center.

Exploring the efficacy of structured nursing via web-based interaction platforms in sustaining hemodialysis patients.

BACKGROUND: Discussed based on the network interactive platform of structured care for patients with chronic renal failure (CRF) in the process of hemodialysis. OBJECTIVE: This study seeks to elucidate the application value of structured nursing, deployed through network interaction platforms, in sustaining patients undergoing maintenance hemodialysis. METHODS: A total of 62 patients diagnosed with Chronic Renal Failure (CRF) between April 2022 and August 2023 were randomly allocated into two distinct care groups: conventional and structured nursing care based on a web-interactive platform. Both cohorts were comparatively analyzed with respect to psychological states, quality of life within therapeutic interventions, and relationships with complications. Renal function indicators, including Creatinine Clearance (Ccr), Serum Creatinine (SCr), and Blood Urea Nitrogen (BUN), were subjected to Pearson analysis to appraise their predictive value in prognostication, while Receiver Operating Characteristic (ROC) curve analysis was constructed to further discern their diagnostic precision. RESULTS: Post-intervention, notable improvements were observed in the emotional states of patients in both cohorts, with the structured care group exhibiting significantly lower Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) scores (p< 0.05). Furthermore, patients under the web-interactive structured nursing regimen demonstrated superior overall adherence, a reduced incidence rate of complications, and markedly higher scores in quality of life assessments compared to those under conventional care (p< 0.05). The derived cut-off values for Ccr, SCr, and BUN were 32.5 ml/min, 251.5 umol/L, and 14.5 mmol/L, respectively, with sensitivities and specificities pegged at 0.645% and 0.645% for Ccr, 0.774% and 0.548% for SCr, and 0.774% and 0.774% for BUN. The corresponding areas under the ROC curve (AUC) for each parameter were 0.816, 0.653, and 0.856, respectively. CONCLUSION: Comprehensive hemodialysis care for patients with chronic renal failure can improve self-care ability to improve quality of life and reduce the incidence of complications, which has great potential for clinical progress and is worthy of further research.

Proteome-wide mendelian randomization identifies novel therapeutic targets for chronic kidney disease.

There is an urgent need to pinpoint novel targets for drug discovery in the context of chronic kidney disease (CKD), and the proteome represents a significant pool of potential therapeutic targets. To address this, we performed proteome-wide analyses using Mendelian randomization (MR) and colocalization techniques to uncover potential targets for CKD. We extracted summary-level data from the ARIC study, focusing on 7213 European American (EA) individuals and 4657 plasma proteins. To broaden our analysis, we incorporated genetic association data from Icelandic cohorts, thereby enhancing our investigation into the correlations with chronic kidney disease (CKD), creatinine-based estimated glomerular filtration rate (eGFRcrea), and estimated glomerular filtration rate (eGFR). We utilized genetic association data from the GWAS Catalog, including CKD (765,348, 625,219 European ancestry and 140,129 non-European ancestry), eGFRcrea (1,004,040, European ancestry), and eGFR (567,460, European ancestry). Employing MR analysis, we estimated the associations between proteins and CKD risk. Additionally, we conducted colocalization analysis to evaluate the existence of shared causal variants between the identified proteins and CKD. We detected notable correlations between levels predicted based on genetics of three circulating proteins and CKD, eGFRcrea, and eGFR. Notably, our colocalization analysis provided robust evidence supporting these associations. Specifically, genetically predicted levels of Transcription elongation factor A protein 2 (TCEA2) and Neuregulin-4 (NRG4) exhibited an inverse relationship with CKD risk, while Glucokinase regulatory protein (GCKR) showed an increased risk of CKD. Furthermore, our colocalization analysis also supported the associations of TCEA2, NRG4, and GCKR with the risk of eGFRcrea and eGFR.

Study on the occurrence and influencing factors of gastrointestinal symptoms in hemodialysis patients with uremia.

BACKGROUND: Gastrointestinal symptoms are common in patients with uremia undergoing hemodialysis, and these symptoms seriously affect patients' prognosis. AIM: To assess the occurrence and factors influencing gastrointestinal symptoms in patients with uremia undergoing hemodialysis. METHODS: We retrospectively selected 98 patients with uremia who underwent regular hemodialysis treatment in the blood purification center of our hospital from December 2022 to December 2023. The gastrointestinal symptoms and scores of each dimension were evaluated using the Gastrointestinal Symptom Grading Scale (GSRS). Patients were divided into gastrointestinal symptoms and no gastrointestinal symptom groups according to whether they had gastrointestinal symptoms. The factors that may affect gastrointestinal symptoms were identified by single-factor analysis. Multiple logistic regression analysis was performed to identify independent risk factors for gastrointestinal symptoms. RESULTS: Gastrointestinal symptoms included indigestion, constipation, reflux, diarrhea, abdominal pain, and eating disorders, and the total average GSRS score was 1.35 ± 0.47. This study showed that age, number of tablets, dialysis time, glucocorticoid, parathyroid hormone (PTH), combined diabetes mellitus and C-reactive protein (CRP) were independent risk factors for gastrointestinal symptoms in patients with uremia undergoing hemodialysis, whereas body mass index (BMI), hemoglobin (Hb), and urea clearance index were independent protective factors (P < 0.05). CONCLUSION: Gastrointestinal symptoms are mostly mild in patients with uremia undergoing hemodialysis, most commonly including dyspepsia, eating disorders, and gastroesophageal reflux. The independent influencing factors mainly include the BMI, age, number of pills taken, dialysis time, urea clearance index, Hb, use of glucocorticoids, and thyroid hormone level. PTH, CRP, and diabetes are clinically related factors influencing the occurrence of gastrointestinal symptoms, and targeted prevention can be performed.

Protocol for the process evaluation of the GOAL trial: investigating how comprehensive geriatric assessment (CGA) improves patient-centred goal attainment in older adults with chronic kidney disease in the outpatient setting.

INTRODUCTION: The GOAL Cluster Randomised Controlled Trial (NCT04538157) is now underway, investigating the impact of comprehensive geriatric assessment (CGA) for frail older people with chronic kidney disease (CKD). The primary outcome is the attainment of patient-identified goals at 3 months, assessed using the goal attainment scaling process. The protocol requires a dedicated process evaluation that will occur alongside the main trial, to investigate issues of implementation, mechanisms of impact and contextual factors that may influence intervention success. This process evaluation will offer novel insights into how and why CGA might be beneficial for frail older adults with CKD and provide guidance when considering how to implement this complex intervention into clinical practice. METHODS AND ANALYSIS: This process evaluation protocol follows guidance from the Medical Research Council and published guidance specific for the evaluation of cluster-randomised trials. A mixed methodological approach will be taken using data collected as part of the main trial and data collected specifically for the process evaluation. Recruitment and process data will include site feasibility surveys, screening logs and site issues registers from all sites, and minutes of meetings with intervention and control sites. Redacted CGA letters will be analysed both descriptively and qualitatively. Approximately 60 semistructured interviews will be analysed with a qualitative approach using a reflexive thematic analysis, with both inductive and deductive approaches underpinned by an interpretivist perspective. Qualitative analyses will be reported according to the Consolidated criteria for Reporting Qualitative research guidelines. The Standards for Quality Improvement Reporting Excellence guidelines will also be followed. ETHICS AND DISSEMINATION: Ethics approval has been granted through Metro South Human Research Ethics Committee (HREC/2020/QMS/62883). Dissemination will occur through peer-reviewed journals and feedback to trial participants will be facilitated through the central coordinating centre. TRIAL REGISTRATION NUMBER: NCT04538157.

UK survey of patient and caregiver perspectives on the impact of chronic kidney disease-associated anaemia.

OBJECTIVE: Chronic kidney disease (CKD)-associated anaemia has substantial biopsychosocial impacts. This study explores the impact of CKD-associated anaemia and treatment preferences from the patient perspective. DESIGN: Cross-sectional survey. SETTING: Anonymised online survey implemented by Ipsos UK on behalf of the National Kidney Federation and GSK from October 2022 to January 2023. PARTICIPANTS: Data were collected from UK adults living with CKD (self-reported). PRIMARY AND SECONDARY OUTCOME MEASURES: Outcome measures were exploratory and not predefined. The cross-sectional survey was designed to explore the biopsychosocial impact of living with anaemia on individuals with CKD; their unmet needs; the treatment strategies typically implemented and the associated barriers/facilitators to adherence; the healthcare professional-patient relationship with regard to anaemia diagnosis and management. RESULTS: Of 101 participants, 90 (89%) were patients with CKD and 11 (11%) were informal carers. 96 (95%) participants reported symptom(s) relevant to their experience of CKD. 88 (87%) participants reported symptom(s) associated with anaemia and 61 (64%) expressed an impact on daily life including 18 (19%) unable to perform daily activities, 13 (14%) unable to go to work and 9 (9%) reporting poor social life/interactions. 85 (84%) participants reported they have received treatment for anaemia: intravenous iron (n=55, 54%), iron tablets (n=29, 29%), erythropoietin-stimulating agents (ESAs) via an autoinjector (n=28, 28%), ESA injections via a syringe (n=24, 24%), ESA injections via a dialysis machine (n=17, 17%), folic acid (n=22, 22%) and blood transfusion (n=17, 17%). Six of seven (86%) participants who received their ESA from a healthcare professional at home preferred injections whereas 13/27 (48%) participants who injected themselves at home preferred oral tablets. CONCLUSIONS: There is not a 'one-size-fits-all' approach to the management of CKD-associated anaemia. A personalised approach incorporating the treatment preferences of the individual should be explored when discussing treatment options.

Efficacy of Qigong Baduanjin on nutritional status and quality of life in patients on haemodialysis: study protocol for a prospective randomised controlled trial.

INTRODUCTION: Haemodialysis (HD) patients usually engage in a low level of physical activities, which could impact the prognosis and mortality of this group. Fitness Qigong Baduanjin, a physical exercise from traditional Chinese Medicine, is known to have benefit in chronic heart failure patients and peritoneal dialysis patients. However, researches about Baduanjin in HD patients are currently limited. So, the aim of the study is to investigate the current exercise intensity of HD patients and its influencing factors, and to explore the effects of Baduanjin on HD patients. METHODS AND ANALYSIS: This prospective, non-blinded, randomised controlled trial will enrol patients with end-stage kidney disease who were stable on HD for more than 3 months. All eligible participants will be randomly divided into the intervention group undergoing Baduanjin and the control group without Baduanjin in a 1:1 ratio. The intervention group is required to perform Baduanjin two times per day, starting 30 min after breakfast and dinner, 45 min per session for a total of a 6 month, starting from 10 June 2024. Information such as laboratory biochemical examination indicators, radiological examination results and related scales and questionnaires will be collected at baseline, 1 month follow-up, 3 month follow-up and 6 month follow-up. All statistical tests are conducted through the two-tailed test, and a p-value≤0.05 will be considered statistically significant for the difference being tested. The description of quantitative indicators will be used in calculating the number of cases, mean, SD, median and IQR method. The classification indicators will be used to describe the number of cases and percentages (frequency and frequency rate). ETHICS AND DISSEMINATION: The study protocol was approved by the Ethics Committee of the First Affiliated Hospital of Zhejiang Chinese Medical University (V20230521). The results will be reported in a peer-reviewed journal and a relevant academic conference. TRAIL REGISTRATION: ChiCTR2300074659.

Validation of histopathological chronicity scores in native kidney biopsies using light microscopy and digital morphometry for predicting renal outcome.

Quantitative assessment of chronicity changes in native kidney biopsies offer valuable insights in to disease prognosis, despite the strength of qualitative information. Yet, standardization and reproducibility remain challenging. The present study aims to assess and compare the prognostic utility and reproducibility of two chronicity scoring systems based on light microscopy and whole slide imaging with morphometry and also to evaluate the prognostic utility of structural measurements: cortical non-sclerotic glomerular (NSG) density and NSG area/volume. We designed a retrospective longitudinal study involving 101 adult and paediatric patients who underwent native kidney biopsies. Chronicity scoring was performed using two semi-quantitative methods: Method 1 (method proposed in PMID: 28314581) and Method 2 (method proposed in PMID: 32516862), under light microscopy as well as on whole-slide scanned images, and assessed for prognostic utility. Kidney-Failure-Risk-Equation (KFRE) was employed in combination with chronicity-scoring-methods and assessed for predictive capability. Interobserver reproducibility for the two chronicity methods was studied among three renal pathologists. Structural measurements were performed on whole-slide- scanned-images. Both the chronicity scoring methods significantly predicted decline in estimated glomerular filtration rate (eGFR) and persistent need for renal replacement therapy in follow-up. Method 1 combined with KFRE, outperformed Method 2 in predicting renal survival. Method 2 however showed higher interobserver reproducibility. Combined KFRE plus histopathological scoring methods showed better predictive accuracy. The study validates the precision of chronicity scoring using whole slide scanned images. The morphometric structural measurements showed significant correlations with follow-up eGFR, thereby providing supplementary prognostic information.

A Rare Cause of Hypotension in Routine Hemodialysis: Secondary Adrenal Insufficiency.

Hypotension is a common complication during hemodialysis that develops due to high ultrafiltration rate and sometimes requires intravenous fluid replacement. Intradialytic hypotension may reduce the effectiveness of dialysis and contributes to hemodialysis-related morbidity and mortality. Adrenal insufficiency is one of the causes of hypotension in the community. Our case was diagnosed with end-stage renal failure and was undergoing routine hemodialysis with a central venous catheter 3 days a week. Upon the patient's hypotension attacks during the dialysis sessions and hypoglycemia attacks in the follow-ups, the morning cortisol was 6.2 µg/dL. Adrenocorticotropic hormone was 39 pg/mL, and testosterone was 0.0442 ng/mL. Adrenocorticotropic hormone stimulation test was performed on the patient with 250 mcg tetracosactide. The patient did not show adequate cortisol response, was detected to have partial empty sella on pituitary magnetic resonance imaging, and was diagnosed with secondary adrenal insufficiency, and then the hemodialysis hypotension improved with prednisolone treatment. We present a case of adrenal insufficiency, which is a rare cause of hypotension in patients on routine hemodialysis.

Cardiovascular Risk in Pediatric Renal Transplant Recipients.

BACKGROUND: The survival of pediatric chronic kidney disease (CKD) patients has improved in recent decades due to advances in dialysis and transplantation. However, cardiovascular disease (CVD) emerges as the main cause of mortality in patients with CKD. OBJECTIVES: To estimate cardiovascular risk in children with CKD at least 1 year after kidney transplantation. In addition, the possible association of cardiovascular risk with classic biochemical markers and potential new markers of this outcome was investigated. METHODS: An observational ambidirectional (retrospective capture of risk factors and prospective study of outcomes) research including 75 patients who underwent renal transplant between 2003 and 2013 with postoperative follow-up of at least 1 year was conducted. The outcome variables adopted were the LV mass Z-score and the presence of coronary calcification on computed tomography using calcium Agatston score. RESULT: Only one patient had an elevated calcium score, and three children (4%) had an LV mass Z-score ≥ 2.0. After multivariable analysis, only gender, serum triglyceride, and serum renalase concentration remained significantly associated with LV mass. CONCLUSION: The low incidence of cardiovascular changes in the population studied confirms the benefit of transplantation for the cardiovascular health of children. Nevertheless, long-term follow-up of these patients is recommended, given the limited duration of kidney function provided by transplantation and the high likelihood of further dialysis and kidney transplants being required in these children.

Mortality and morbidity associated with new onset acute kidney injury in critically ill COVID-19 infection patients.

BACKGROUND: The recent global pandemic due to severe acute respiratory syndrome coronavirus-2 resulted in a high rate of multi-organ failure and mortality in a large patient population across the world. As such, a possible correlation between acute kidney injury (AKI) and increased mortality rate in these patients has been suggested in literature. METHODS: This is a two-year retrospective study of critically ill adult patients infected with COVID-19 that were admitted to the intensive care unit (ICU) on ventilatory support. Two groups of patients were identified in this study, those who were directly admitted to the ICU or those who were initially admitted to the Medical Floor and were later transferred to the ICU due to either worsening respiratory status or change in their hemodynamic conditions. Within each group, three subgroups were created based on the status of AKI, namely, those who did not develop AKI, those who developed AKI, and those who with previous history of dialysis dependent AKI. RESULTS: The AKI subgroup had the highest mortality rate in the ICU and Floor patients. Of note, those patients who were directly admitted to the Floor and were later transferred to the ICU for worsening conditions also experienced a higher mortality rate if they had developed AKI during their course of hospital stay. CONCLUSIONS: This study identified a statistically significant higher mortality in patients who developed AKI than those who did not develop AKI among critically ill patients.

Intractable Hiccups in a Patient With End-Stage Renal Disease: A Five-Month Ordeal Resolved Through Hemodialysis.

Hiccups, a common and usually self-limiting condition, are caused by involuntary, spasmodic contractions of the diaphragm and intercostal muscles, followed by the sudden closure of the glottis. While most cases resolve spontaneously, persistent hiccups (lasting 48 hours to one month) and intractable hiccups (lasting more than one month) require medical attention. Intractable hiccups, although rare, can significantly impair a patient's quality of life. The etiology of intractable hiccups is diverse, but they are often associated with serious underlying medical conditions, such as severe renal dysfunction and uremia. We present the case of a 72-year-old male patient with stage IV chronic kidney disease (CKD) who developed intractable, violent hiccups following a mild COVID-19 infection. Despite treatment attempts with chlorpromazine and baclofen, the hiccups persisted for five months and only resolved after the initiation of hemodialysis. Interestingly, the patient's renal function deteriorated significantly during the period of hiccup persistence, suggesting a possible link between the hiccups and the progression of CKD, likely exacerbated by COVID-19. This case highlights the challenges of managing intractable hiccups in patients with advanced CKD and emphasizes the importance of addressing underlying metabolic derangements in such complex clinical scenarios. Moreover, it contributes to the growing evidence supporting the role of dialysis in resolving intractable hiccups associated with severe renal dysfunction.

Blood purification therapy in chronic renal failure and its impact on renal index, serological index, and inflammatory factors.

Introduction: This study aimed to explore the clinical effects of blood purification therapy in patients with chronic renal disease, measured by renal function index and inflammation. Methodology: Data were collected from a tertiary care hospital in Pakistan between June 2022 and September 2023. Eighty-four patients undergoing maintenance hemodialysis for chronic renal failure were retrospectively included in this cohort. Results: Age, sex, BMI, course of disease, primary disease, and educational level were not related to the response to blood purification treatment. Blood purification therapy positively affected renal function, serological indices, and inflammatory factors (P<0.05). Conclusion: Blood purification therapy can improve toxin clearance and renal function and reduce inflammation. Therefore, the authors can conclude that this is an effective therapy for our population.

Perioperative Risk Factors for Early Major Amputation Following First-Time Diabetic Forefoot Amputation.

BACKGROUND: Despite a meticulous multidisciplinary team approach, limb salvage remains uncertain even after the initial forefoot amputation in patients with end-stage diabetes. Which of many factors strongly influence the early failure of the limb salvage strategy remains unknown. This study aimed to analyze perioperative independent risk factors for major amputation within 1 year following first-time diabetic forefoot amputation. METHODS: Perioperative variables of 808 diabetic forefoot amputations performed in a tertiary referral center specialized for organ transplantation and end-stage diabetes were analyzed. Major amputations were performed in 104 patients (12.9%) throughout follow-up, and 77 (74%) of 104 patients had their major amputation within 1 year. Cox proportional hazards were examined to assess the risk factors for major amputation performed within 1 year. RESULTS: In univariate analysis, 18 possible risk factors significantly differed between patients with and without early major amputation. In stepwise multivariable analysis, chronic renal failure (CRF), peritoneal dialysis, and bilateral initial amputation were strong risk factors for early major amputation, with hazard ratios of 2.973 (95% CI 1.805-4.896, P < .0001), 2.558 (95% CI 1.113-5.881, P = .027), and 2.515 (95% CI 1.318-4.798, P = .005), respectively. CONCLUSION: Regardless of kidney transplantation (KT) status, CRF strongly predicts >20% chance of major amputation within 1 year after the first diabetic forefoot amputation.

Higher post procedural bleeding in patients with advanced chronic kidney disease undergoing percutaneous coronary intervention.

BACKGROUND: Advanced chronic kidney disease (ACKD) is common in patients undergoing percutaneous coronary intervention (PCI). Post-PCI bleeding has been shown to increase mortality and remains an important challenge in these patients. Previous studies have shown increased post-PCI bleeding in CKD patients but often ACKD patients are excluded from these trials. The goal of this study was to evaluate if patients undergoing PCI with advanced renal disease have higher bleeding complications. METHODS: We analyzed the National Inpatient Sample (NIS) database to compare the post-PCI bleeding rates for ACKD (CKD stage 3 and above) undergoing PCI between 2006 and 2011 to those without ACKD in patients over the age of 40. Specific ICD-9 CM codes were used to identify these patients. RESULTS: A total of 49,192 patients had post-PCI bleeding during the study period of which 3,675 (7.5%) had ACKD. Patients with ACKD were older (68.7±11.7 years). During the study period, there was a decline in post-PCI bleeding rates in both ACKD and control groups. Patients with ACKD have significantly higher post-PCI bleeding rates compared to the control group. For example, in 2006, 133.9 in patients with ACKD had bleeding vs. 104.4 per 100,000 in patients without ACKD (P<0.05). After multivariate adjustment for bassline comorbidities, ACKD remained independently associated with post-PCI bleeding risk (OR: 1.07, CI: 1.03-1.11, P<0.001). CONCLUSION: Despite the overall decline in post-PCI bleeding in patients undergoing PCI, ACKD remains independently associated with post-procedural bleeding.

The utilization of renal dialysis: a comprehensive study in Saudi Arabia.

BACKGROUND: Understanding the trend of utilization of renal dialysis in Saudi Arabia (SA) is fundamental as it provides a general overview of renal care. The practice of renal dialysis assists in identifying challenges, opportunities, and potential areas for improvement in the provision of the services. OBJECTIVES: This research investigated the utilization of renal dialysis services in SA by exploring the number of renal dialysis centers, hemodialysis machines (HD), and peritoneodialysis patients. METHODS: The dataset for this study was derived from a collaboration between the General Authority of Statistics (GaStat) and the Ministry of Health (MoH), focusing on indicators for renal dialysis centers and patients across health sectors in 2021. Analysis was conducted using MS Excel 365 and IBM SPSS Version 29, incorporating multiple regression techniques. The health sector was treated as the dependent variable. At the same time, the number of hemodialysis (HD) machines and the counts of HD and peritoneal dialysis patients were considered independent variables. RESULTS: Around 275 renal dialysis centers, over 8000 HD machines, 20,440 HD patients, and 1,861 peritoneal patients were tallied from two resources. The findings revealed a negative relationship between the health sector and several renal dialysis centers and peritoneodialysis patients, as demonstrated by p < 0.05 in multiple regression analysis. CONCLUSION: The number of renal dialysis centers influences the availability of HD machines, affecting the number of HD and peritoneodialysis patients. Most national patients preferred MoH over other semi-governmental and private sectors, and vice versa for non-Saudis.

[Characteristics and needs of patients requiring nephrology care: A review of the literature]. / Caractéristiques et besoins des patients nécessitant des soins en néphrologie : une revue de littérature.

Chronic kidney disease (CKD) is a public health problem. However, the management of patients with CKD is confined to the diagnosis of the disease and its conventional treatment by dialysis or renal transplantation. The aim of this article is to describe the specific characteristics of patients suffering from kidney disease and to determine their needs according to the stage of their renal disease.
