ABSTRACT
Objective: To evaluate the effects of the multiple single cannulation technique (MUST) on the outcomes of arteriovenous graft (AVG). Methods: A retrospective study of AVG created between January 2018 and December 2021 at the First Affiliated Hospital of Zhengzhou University was conducted. The clinical data of patients and their follow-up data for venous access were analyzed. Subjects were divided into the MUST group or the non-MUST group according to whether MUST was used. The cumulative patency rate and complication incidence were compared between the two groups. Logistic regression was applied to analyze the influencing factors of applying MUST in AVG. Results: The MUST group included 115 AVG and the non-MUST group, 122 AVG. The 1-year, 2-year, 3-year, and 4-year cumulative patency rates of the MUST group were 100%, 99.1%, 95.2%, 85.4%, and 73.2%, respectively, while those for the non-MUST group were 97.5%, 92.7%, 77.7%, 69.7%, and 50.0%, respectively, with the 2-year and 3-year patency rates showing significant difference (P=0.022, P=0.004). The standard intervention rate expressed in (median [interquartile range]) in the MUST group was significantly lower than that in the non-MUST group (0.46 [0.00, 0.94] vs. 0.97 [0.60, 1.59], Z=-5.808, P<0.001). A total of 24 (20.9%) AVG in the MUST group and 60 (49.2%) AVG in the non-MUST group had a standard intervention rate >1.0 per patient-year, with significant difference between the two groups. Three (2.6%) AVG in the MUST group and 7 (5.7%) AVG in the non-MUST group were complicated by aneurysm (χ 2=20.737, P<0.001). One (0.9%) AVG in the MUST group and 6 (4.9%) AVG in the non-MUST group had graft infection, with the difference between the groups showing no significance (P=0.121). Multivariate logistic regression showed that dialysis in the alliance facilities (odds ratio [OR]=2.713, 95% confidence interval [CI]: 1.698-4.336, P<0.001], and excellent follow-up [OR=2.189, 95% CI: 1.221-3.927, P=0.009] were the influencing factors of applying MUST in AVG. Conclusion: MUST improves the cumulative patency of AVG and decreases the intervention frequency and the incidence of aneurysm without increasing the risk of graft infection.

PURPOSE: Although minimally invasive colorectal surgery has been proven to have a shorter hospital stay and fewer short-term complications than open surgery, the advantages of laparoscopic surgery for colorectal cancer patients undergoing hemodialysis have not been validated. This study compared the outcomes of open and laparoscopic approaches in these patients. MATERIALS AND METHODS: Between January 2007 and December 2020, we retrospectively analyzed the clinical data of 78 hemodialysis patients who underwent curative-intent, elective colorectal surgery. Patients were divided into two groups according to the surgical method: open and laparoscopic. RESULTS: Postoperative morbidity (p = 0.480) and mortality (p = 0.598) rates and length of hospital stay (28.8 vs. 27.5 days, p = 0.830) were similar between the groups. However, laparoscopic surgery patients had a shorter return to clear liquid, full liquid, or soft food time than open surgery patients (p < 0.001, p = 0.007, and p = 0.002, respectively). Disease-free survival and long-term cancer-specific survival rates were also similar between the two groups (p = 0.353 and p = 0.201, respectively). Multivariate analysis revealed that intraoperative blood transfusion was a risk factor for severe complications and mortality (OR 6.055; p = 0.046), and the odds ratio (OR) of laparoscopic surgery was not significantly greater than that of open surgery (OR = 0.537, p = 0.337). CONCLUSION: Although laparoscopic surgery did not result in hemodialysis patients having a shorter postoperative hospital stay, our results suggest that the laparoscopic approach is as safe as open surgery for hemodialysis patients and may be beneficial for shortening the return time to food intake.

OBJECTIVE: This study aimed to evaluate inflammatory biomarkers in patients undergoing peritoneal dialysis and investigate their association with all-cause mortality or transfer to hemodialysis. METHODS: This prospective cohort study included 43 patients undergoing peritoneal dialysis. Plasma levels of cytokines were measured using flow cytometry and capture enzyme-linked immunosorbent assay. Biomarkers were categorized based on their respective median values. Survival analysis was conducted using the Kaplan-Meier estimator, considering two outcomes: all-cause mortality and transfer to hemodialysis. RESULTS: After adjusting for confounding factors, plasma levels above the median of the levels of CCL2 and plasma, as well as below the median of TNF-α, and the median of dialysate IL-17 levels, were associated with an increased risk of experiencing the specified outcomes after approximately 16 months of follow-up. CONCLUSION: These findings suggest that inflammatory biomarkers may be a valuable tool for predicting all-cause mortality and transfer to hemodialysis in patients undergoing peritoneal dialysis.

OBJECTIVES: Parathyroidectomy (PTX) is an effective treatment for refractory secondary hyperparathyroidism (SHPT), but it can lead to hungry bone syndrome (HBS), significantly threatening the health of maintenance haemodialysis (MHD) patients. While previous studies have analyzed the risk factors for HBS post-PTX, the predictive performance and clinical applicability of these risk models need further validation. This study aims to construct and validate a risk prediction model for HBS in MHD patients with SHPT post-PTX. METHODS: A retrospective analysis was conducted on 368 MHD patients with SHPT who underwent PTX at Changsha Jieao Nephrology Hospital from January 2020 to December 2021. Patients were divided into a HBS group and a non-HBS group based on the occurrence of HBS. General data, surgical information, and biochemical indicators were compared between the 2 groups. Multivariate logistic regression was used to identify factors influencing HBS, and a risk prediction model was established. The model's performance was evaluated using receiver operator characteristic (ROC) curves, decision curves, and calibration curves. External validation was performed on 170 MHD patients with SHPT who underwent PTX at the Third Xiangya Hospital of Central South University from January to December 2022. RESULTS: The incidence of HBS post-PTX in MHD patients with SHPT was 60.60%. Logistic regression analysis identified preoperative bone involvement (OR=3.908, 95% CI 2.179 to 7.171), preoperative serum calcium (OR=7.174, 95% CI 2.291 to 24.015), preoperative intact parathyroid hormone (iPTH) (OR=1.001, 95% CI 1.001 to 1.001), preoperative alkaline phosphatase (ALP) (OR=1.001, 95% CI 1.000 to 1.001), and serum calcium on the first postoperative day (OR=0.006, 95% CI 0.001 to 0.038) as independent risk factors for HBS (all P<0.01). The constructed risk prediction model demonstrated good predictive performance in both internal and external validation cohorts. The internal validation cohort showed an accuracy of 0.821, sensitivity of 0.890, specificity of 0.776, Youden index of 0.666, and area under the curve (AUC) of 0.882 (95% CI 0.845 to 0.919). The external validation cohort showed an accuracy of 0.800, sensitivity of 0.806, specificity of 0.799, Youden index of 0.605, and AUC of 0.863 (95% CI 0.795 to 0.932). CONCLUSIONS: Preoperative bone involvement, serum calcium, iPTH, ALP, and serum calcium on the first postoperative day are influencing factors for HBS in MHD patients with SHPT post-PTX. The constructed risk prediction model based on these factors is reliable.

Dialysis patients often have inadequate health literacy, affecting self-care and outcomes. This study used LINE app to provide personalized health education to Taiwanese dialysis patients and collected physiological data via wearables. While physical activity levels remained unchanged, participants' disease literacy significantly improved post-intervention. Patients' health literacy will evaluate by Health Literacy Questionnaire for Taiwanese Hemodialysis patients (HLQHD). The findings highlight technology-driven interventions' potential to enhance health literacy and disease management among dialysis patients.

Importance: Randomized clinical trials have shown that sacubitril-valsartan reduces the risks of mortality and hospitalization in patients with heart failure with reduced ejection fraction (HFrEF), but patients with kidney failure requiring dialysis were excluded. Objective: To investigate the comparative effectiveness of sacubitril-valsartan vs angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (ACEIs or ARBs) in patients with HFrEF requiring hemodialysis. Design, Setting, and Participants: This retrospective, 1:1 propensity score-matched comparative effectiveness study included patients who were 18 years or older with HFrEF, enrolled in Medicare Parts A, B, and D, and survived at least 90 days receiving in-center hemodialysis from July 8, 2015, to December 31, 2020. Patients were excluded for less than 180 days of continuous Medicare Parts A, B, and D primary payer coverage or prior dispensing of sacubitril-valsartan. Data analysis was conducted from September 23, 2023, to June 25, 2024. Exposures: New use of sacubitril-valsartan vs new or continued use of ACEIs or ARBs. Main Outcomes and Measures: The associations between initiation of sacubitril-valsartan therapy and all-cause mortality, cardiovascular mortality, all-cause hospitalization, and HF hospitalization were assessed using Cox proportional hazards regression models in a propensity score-matched sample. Results: Participants included 1:1 matched pairs of 1434 sacubitril-valsartan users and 1434 ACEI or ARB users (mean [SD] age, 64 [13] years). Of the 2868 matched participants, 996 (65%) were male; 987 (34%) were Black or African American and 1677 (58%) were White; and median dialysis vintage was 3.8 (IQR, 1.8-6.3) years. The median follow-up was 0.9 (IQR, 0.4-1.7) years. Sacubitril-valsartan (vs ACEI or ARB) therapy was associated with a reduction in all-cause mortality (hazard ratio [HR], 0.82 [95% CI, 0.73-0.92]) and all-cause hospitalization (HR, 0.86 [95% CI, 0.79-0.93]) but not cardiovascular mortality (HR, 1.01 [95% CI, 0.86-1.19]) or HF hospitalization (HR, 0.91 [95% CI, 0.82-1.02]). There was a decrease in hyperkalemia (HR, 0.71 [95% CI, 0.62-0.81]) and no difference in hypotension (HR, 0.99 [95% CI, 0.83-1.19]). Only 195 participants (14%) ever received the maximum combination dose of sacubitril (97 mg twice daily) and valsartan (103 mg twice daily). Conclusions and Relevance: In this comparative effectiveness study of patients with HFrEF requiring hemodialysis, sacubitril-valsartan therapy was associated with beneficial effects in all-cause mortality and all-cause hospitalization.

Physical performance in hemodialysis patients declines and serves as a cardiovascular disease (CVD) incidence and mortality predictor. However, lower extremity function's role remains unclear. This study aimed to quantify the association between lower extremity function and CVD risk in hemodialysis patients. This was a multicenter cross-sectional study enrolling 868 participants (532 males, 336 females) from seven hemodialysis centers in Shanghai, China. Patients were divided into three groups per lower extremity function, evaluated by short physical performance battery (SPPB) scores: 0-6, 7-9, and 10-12. Upper extremity function was quantified through grip strength assessment. CVD risk was assessed using the Framingham Risk Score. Approximately 35% of hemodialysis patients had impaired lower extremity function (SPPB score < 10). Participants with high SPPB scores had stronger handgrip and lower Framingham CVD risk scores than those with low and moderate SPPB scores (p < 0.05). After adjusting clinical confounders, SPPB was independently associated with CVD risk, as a categorized variable (odds ratio: 0.577, 95% confidence interval [CI]: 0.388-0.857, p = 0.006) and as a continuous variable (odds ratio: 0.858, 95% CI: 0.772-0.953, p = 0.004). An SPPB score < 10 predicted an increased CVD risk (area under curve: 0.649, 95% CI: 0.599-0.699, p < 0.001). Causality between physical performance and CVD risk was not considered. Some upper limb results may not be generalizable to peritoneal dialysis and kidney transplant patients. Lower extremity function was significantly associated with CVD risk in hemodialysis patients. Further studies are needed to explore the long-term relationship between lower extremity function and CVD risk.

BACKGROUND: Uncontrolled gout can cause articular impairment but is also associated with a global and cardiovascular excess mortality, especially in dialysis population. Data documented within existing research is not conclusive regarding gout flares evolution during hemodialysis and their control by urate lowering therapy (ULT). Without clear guidelines concerning hemodialysis patients management with chronic gout, this study proposes to investigate whether gout flare incidence reduction could be observed on this population treated by urate lowering therapy versus patients without treatment. METHODS: We performed a retrospective cohort study in two hemodialysis centers in France. Were selected patients over 18 years old with a gout history who started hemodialysis between January 2005 and September 2015. Demographics and clinicals data were recorded at hemodialysis start and throughout 5 years of follow up. Gout flare was defined as presence of uric acid crystal in joint punction or clinically diagnosed as such with a colchicine prescription. All statistical analysis were performed in SAS® version 9.4 (SAS Institute Inc., Cary, NC). RESULTS: One hundred eighty-one patients have been included, mean age at dialysis initiation was 68.6 years (± 12.4) with 72% of men, 54% were treated by ULT: 89.7% by allopurinol and 9.3% by febuxostat. One patient received both treatments successively. After hemodialysis initiation, 35.36% patients had experienced at least one gout flare. The appearance of at least one gout flare concerned 50% of patients in no ULT group and 22.68% patients in ULT group (p = 0.0002). Dialysis efficiency was measured at regular interval during follow-up and was similar in both groups. To study the association strength between clinical factors and gout flares occurrences, a Cox model was performed; ULT is a protector factor of gout flare (HR:0,42, CI 95: 0,25-0,71). The proportion of serum urate values within the target (median 53% vs 29.3%, p < 0.0001) was significantly higher in ULT group versus no ULT group (median 53% vs 29.3%, p < 0.0001). CONCLUSION: Urate lowering therapy limit new gout flares occurrence in hemodialysis patients with gout historyCollaboration between rheumatologists and nephrologists may help to update guidelines for urate-lowering therapies in patients on dialysis.

RATIONALE: Pharmacological mechanism of Roxadustat in the treatment of renal anemia. PATIENT CONCERNS: To investigate the efficacy and safety of combined Roxadustat and erythropoiesis stimulator (ESA) treatment of renal anemia in hemodialysis patients with secondary hyperparathyroidism. DIAGNOSES: A retrospective analysis was conducted on hemodialysis patients with renal anemia and secondary hyperparathyroidism treated with ESAs alone, who were admitted to our hospital from March 2022 to December 2022. INTERVENTIONS: The patients were treated with Roxadustat combined with ESAs for 3 months, during which oral iron supplementation was given, and the changes in Hb levels and laboratory-related indicators before and after the combined treatment were analyzed. OUTCOMES: The results showed that a total of 13 patients received combination therapy, with a significant increase in Hb compared to ESAs alone (tâ =â -3.955, Pâ =â .002). The Hb qualification rate was 38.46%, and the ∆Hb response rate was 76.92%. The parathyroid hormone significantly decreased with a statistically significant difference (Zâ =â -2.062b, Pâ =â .039). Hemoglobin (RBC), total iron binding capacity, and serum ferritin (male) were significantly increased compared to ESAs alone. Total cholesterol and low-density lipoprotein were significantly lower than ESAs alone. The differences in the changes in the above indicators were statistically significant (Pâ <â .05). There was no statistically significant difference in changes in other laboratory-related indicators (Pâ >â .05). No adverse reactions were observed during the combined treatment of 13 patients. LESSONS SUBSECTIONS: The combination of Roxadustat and ESAs can effectively improve renal anemia in hemodialysis patients with secondary hyperparathyroidism, as well as improve indicators of hyperparathyroidism and blood lipid levels with high levels of safety. This combined treatment thus provides a new and safe treatment method for these patients.

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.

BACKGROUND: While osteoarthritis is a significant issue within the hemodialysis population and contributes to reduced quality of life, pain related to osteoarthritis is poorly managed by healthcare professionals (HCPs) in hemodialysis settings due to the absence of clinical guidance applicable to this population. The purpose of this study was to explore the perceptions of HCPs on the barriers and facilitators to using a clinical decision support tool for osteoarthritis pain management in the hemodialysis setting. METHODS: A qualitative descriptive study was conducted. Purposeful and snowball sampling techniques were used to recruit hemodialysis clinicians from academic and community settings across multiple Canadian provinces. One-to-one interviews were conducted with clinicians using a semi-structured, open ended interview guide informed by the Theoretical Domains Framework, a behavior change framework. A general inductive approach was applied to identify the main themes of barriers and facilitators. RESULTS: A total of 11 interviews were completed with 3 nephrologists, 2 nurse practitioners and 6 pharmacists. Findings revealed 6 main barriers and facilitators related to the use of the clinical decision support tool. Alignment of the tool with practice roles emerged as a key barrier and facilitator. Other barriers included challenges related to the dialysis environment, varying levels of clinician comfort with pain medications, and limited applicability of the tool due to patient factors. An important facilitator was the intrinsic motivation among clinicians to use the tool. CONCLUSIONS: Most participants across the included hemodialysis settings expressed satisfaction with the clinical decision support tool and acknowledged its overall potential for improving osteoarthritis pain management among patients on hemodialysis. Future implementation of the tool may be limited by existing roles and practices at different institutions. Increased collaboration among hemodialysis and primary care teams may promote uptake of the tool.

BACKGROUND AND OBJECTIVE: Renal replacement therapy (RRT) plays a critical role in antimicrobial removal, particularly for low-molecular-weight drugs with low plasma protein binding, low distribution volume and hydrophilicity. Medium cut-off (MCO) membranes represent a new generation in dialysis technology, enhancing diffusive modality efficacy and increasing the cut-off from 30 to 45 kDa, crucial for middle molecule removal. This monocentric randomized crossover pilot study aimed to evaluate the impact of continuous haemodialysis with MCO membrane (MCO-CVVHD) on the removal of piperacillin, tazobactam and meropenem compared with continuous veno-venous hemodiafiltration with standard high-flux membrane (HFM-CVVHDF). METHODS: Twenty patients were randomized to undergo MCO-CVVHD followed by HFM-CVVHDF or vice versa. Extraction ratio (ER), effluent clearance (Cleff) and treatment efficiency were assessed at various intervals. Antibiotic nadir plasma levels were measured for both treatment days. RESULTS: HFM-CVVHDF showed greater ER compared with MCO-CVVHD for meropenem (ß = - 8.90 (95% CI - 12.9 to - 4.87), p < 0.001) and tazobactam (ß = - 8.29 (95% CI - 13.5 to - 3.08), p = 0.002) and Cleff for each antibiotic (meropenem ß = - 10,206 (95% CI - 14,787 to - 5787), p = 0.001); tazobactam (ß = - 4551 (95% CI - 7781 to - 1322), p = 0.012); piperacillin (ß = - 3913 (95% CI - 6388 to - 1437), p = 0.002), even if the carryover effect influenced the Cleff for meropenem and tazobactam. No difference was observed in nadir plasma concentrations or efficiency for any antibiotic. Piperacillin (ß = - 38.1 (95% CI - 47.9 to - 28.3), p < 0.001) and tazobactam (ß = - 4.45 (95% CI - 6.17 to - 2.72), p < 0.001) showed lower nadir plasma concentrations the second day compared with the first day, regardless the filter type. CONCLUSION: MCO demonstrated comparable in vivo removal of piperacillin, tazobactam and meropenem to HFM.

This study aimed to investigate the relationship between hemodialysis duration (HDD) and retinal nerve fiber layer (RNFL) thickness. A total of 60 patients receiving maintenance hemodialysis and 67 healthy controls were analyzed. Spectral domain optical coherence tomography (SD-OCT) was employed to measure annular RNFL thicknesses. The hemodialysis group exhibited reduced temporal and inferior RNFL thicknesses relative to the control group. In hemodialysis patients, the inferior RNFL thickness was negatively correlated with HDD and positively correlated with intraocular pressure (IOP). Moreover, IOP was positively correlated with HDD. Mediation analysis showed that the negative correlation between HDD and inferior RNFL thickness was mediated by IOP. In conclusion, hemodialysis leads to temporal and inferior RNFL thinning, and the thickness reduction is proportional to hemodialysis duration. However, such changes are not induced by an increase in IOP.

INTRODUCTION: Pregnancy in a woman with heart and chronic renal failure can lead to life-threatening complications for both mother and child. Although such cases are often delivered by cesarean section, few reports have described anesthesia methods. CASE PRESENTATION: We encountered a case in which cesarean section was performed using combined spinal and epidural anesthesia for a pregnant woman with chronic renal and heart failure. The 35-year-old Japanese woman had been undergoing hemodialysis for several years. Heart failure symptoms that appeared during pregnancy initially improved with treatments such as increasing hemodialysis, but recurred. She was admitted to the intensive care unit. The initial plan was to deliver the baby after a few weeks, but further progression of heart failure became a concern. After a clinical conference among staff, a cesarean section with combined spinal and epidural anesthesia was scheduled for 24 weeks, 0 days of gestation. The anticoagulant for dialysis was also changed from heparin to nafamostat in preparation for cesarean section. Monitoring was started with central venous and radial artery pressures before induction of anesthesia. Combined spinal and epidural anesthesia was induced and the cesarean section was completed without complications. Surgery was initiated under continuous administration of phenylephrine, which was intended to avoid hypotension due to anesthesia. The hemodynamic and respiratory status of the patient remained stable postoperatively. After the cesarean section, morphine was administered epidurally and the epidural catheter was removed. CONCLUSION: Cesarean section was safely performed for a pregnant woman with renal and heart failure using combined spinal and epidural anesthesia.

BACKGROUND: To compare the impact of tunneled cuffed catheters (TCCs) and arteriovenous fistulas (AVFs) on outcomes in elderly hemodialysis (HD) patients. METHODS: A retrospective matched cohort study was performed. Propensity score matching (PSM) was applied to balance the baseline conditions, and we compared all-cause mortality, major adverse cardiovascular and cerebrovascular events (MACCEs), hospitalization, and infection rates between AVF and TCC patients ≥70 years old. Cox survival analysis was used to analyze the risk factors for death. RESULTS: There were 2119 patients from our center in the Chinese National Renal Data System (CNRDS) between 1 January 2010 and 10 October 2023. Among these patients, 77 TCC patients were matched with 77 AVF patients. There was no significant difference in all-cause mortality between the TCC and AVF groups (30.1/100 vs. 33.3/100 patient-years, p = 0.124). Among the propensity score-matched cohorts, no significant differences in Kaplan-Meier curves were observed between the two groups (log-rank p = 0.242). The TCC group had higher rates of MACCEs, hospitalization, and infection than the AVF group (33.7/100 vs. 29.5/100 patient-years, 101.2/100 vs. 79.5/100 patient-years, and 30.1/100 vs. 14.1/100 patient-years, respectively). Multivariate analysis showed that high Charlson comorbidity index (CCI) score was a risk factor for death. CONCLUSIONS: There was no significant difference in all-cause mortality between elderly HD patients receiving TCCs and AVFs. Compared with those with a TCC, elderly HD patients with an AVF have a lower risk of MACCEs, hospitalization, and infection.

BACKGROUND: Currently, several studies have explored the association between the modified creatinine index (mCI) and prognosis in patients on hemodialysis (HD). However, some of their results are contradictory. Therefore, this study was conducted to comprehensively assess the role of mCI in predicting prognosis in HD patients through meta-analysis. METHODS: We searched and screened literature from PubMed, Embase, Web of Science, and Cochrane databases from their establishment until March 2024. Relevant data were extracted. The statistical analysis was performed using Stata 15.0, RevMan 5.4, and Meta DiSc 1.4 software. RESULTS: The results showed a positive association between mCI and nutritional status in HD patients (BMI r = 0.19, 95% CI: 0.1-0.28, p = .000; albumin r = 0.36, 95% CI: 0.33-0.39, p = .000; normalized protein catabolic rate (nPCR) r = 0.25, 95% CI: 0.13-0.38, p = .000). In addition, mCI in deceased HD patients was significantly lower than that in HD survivors (SMD = -0.94, 95% CI: -1.46 to -0.42, p = .000). A low mCI was associated with an increased risk of all-cause death in HD patients (HR = 1.95, 95% CI: 1.57-2.42, p = .000). In addition, a low mCI was significantly associated with decreased overall survival (OS) in HD patients (HR = 3.01, 95% CI: 2.44-3.70, p = .000). mCI showed moderate diagnostic accuracy for sarcopenia in both male and female HD patients (male AUC = 0.7891; female AUC = 0.759). CONCLUSIONS: The mCI can be used as a prognostic marker for HD patients, and monitoring mCI may help to optimize the management of HD and improve overall prognosis in patients.

Atypical haemolytic uremic syndrome (aHUS) is a rare disorder characterised by complement-mediated thrombotic microangiopathy (TMA). Despite clinical guidelines, the diagnosis and treatment of aHUS in its early stages remains challenging. This study examined the annual trends in aHUS clinical practices in Japan and explored factors influencing early diagnosis and treatment. Using data from the 2011-2020 Diagnosis Procedure Combination database, 3096 cases with the HUS disease code were identified, of which 217 were confirmed as aHUS and treated with eculizumab or plasma exchange. Early initiation, defined as starting eculizumab or plasma exchange within 7 days of admission, was the focus of the study. Our study revealed no significant changes over time in the number of aHUS diagnoses, cases treated with eculizumab, or early initiation cases. Early initiation cases underwent haemodialysis earlier and had ADAMTS13 activity measured earlier, shorter hospital stays, and lower hospitalisation costs than late initiation cases. In conclusion, we found no increase in the number of newly diagnosed aHUS cases or early treatment initiation over time. Early recognition of TMA and differentiation of the causative disease are crucial for identifying potential aHUS cases, which may lead to better patient prognoses.

With the increasing number of maintenance hemodialysis (MHD) patients, growing attention has been paid to the quality of care. Strengthening care preparedness of family caregivers is essential to improving the nursing quality. The purpose of this study is to explore the care preparedness level of family caregivers of MHD patients and its influencing factors, so as to provide guidance for the development of targeted care interventions. A total of 237 family caregivers of MHD patients were recruited from the hemodialysis room of two tertiary hospitals in Wuhan using the Convenience sampling method. They were surveyed by the general data questionnaire, Care Preparedness Scale and Positive Aspects of Caregiving. Statistical analysis was conducted using IBM SPSS software, version 21.0. The statistical tests conducted in this study were two-tailed, and a significance level of P < 0.05 was deemed as statistically significant. The care preparedness and positive aspects of caregiving scores of family caregivers of MHD patients were 19.05 ± 5.64 and 31.28 ± 7.28 points, respectively. The care preparedness level of family caregivers was significantly positively correlated with positive aspects of caregiving (P < 0.01). The results of multiple linear regression analysis showed that the total nursing time and whether family caregivers had chronic diseases and positive aspects of caregiving were the main factors influencing their care preparedness (all P < 0.05). These three factors accounted for 49.6% of the variance. The care preparedness of family caregivers of MHD patients remains to be continuously improved. Medical staff should emphasize the important role of total nursing time, whether the caregiver has a chronic disease, and positive aspects of caregiving in improving care preparedness in this population. To achieve this end, medical staff can provide targeted support and guidance for caregivers according to the influencing factors, such as implementing group psychological education, strengthening the training, offering social support, remote intervention (including family caregivers' education through the media), and so on. Meanwhile, caregivers should be evaluated dynamically, and information and emotional support should be provided for them.

This case report highlights the effective use of intermittent hemodialysis (IHD) in warming a 71-year-old female patient with severe hypothermia who presented with a rectal temperature of 25 °C and signs of hemodynamic instability. The patient, found unconscious after prolonged exposure to cold exacerbated by alcohol consumption, initially showed some improvement in core temperature through active external rewarming methods. However, soon, her temperature plateaued at 27 °C. Patient was deemed unsuitable for extracorporeal membrane oxygenation (ECMO) or cardiopulmonary bypass (CPB) due to her age, and urgent IHD was initiated. This approach resulted in a stable increase in core temperature at approximately 2.0 °C/hr, along with normalization of lactic acidosis, creatinine phosphokinase, and correction of electrolyte imbalances, culminating in her full recovery and discharge after seven days in the hospital.After reviewing this case alongside similar ones from before, this case report highlights the efficacy and safety of IHD as an efficient, readily available, and less invasive method for rewarming moderate to severe hypothermic patients who are hemodynamically unstable patients but do not have cardiac arrest or renal dysfunction. IHD is especially useful when less invasive cooling devices (Artic Sun/ CoolGard) are not available or more invasive extracorporeal life support options (ECMO/ CPB) are either not indicated or unavailable. IHD can also help improve concurrent electrolyte imbalances and/or toxin buildup. The report further emphasizes the necessity of monitoring for potential complications, such as post-dialysis hypophosphatemia and rebound hyperkalemia, following successful rewarming.
