Background: Blood pressure variability (BPV) is a potential prognostic predictor for all-cause mortality. Objectives: We conducted a retrospective cohort study to compare the prognostic value of long-term BPV with intra-dialytic BPV in hemodialysis (HD) patients. Materials and Methods: We included 611 HD patients and collected their baseline blood pressure (BP) measurements for 1 year and monitored them for 40 months. Long-term BPV was assessed by pre-dialysis BP SD and pre-dialysis absolute BP residual metric. Intra-dialytic BPV was assessed by intra-dialytic BP average real variability and intra-dialytic absolute BP residual. Results: Long-term systolic BPV showed a weak correlation with mean BP, but a stronger correlation with intra-dialytic BPV. High long-term systolic blood pressure (SBP) SD and long-term SBP residual metrics were associated with high all-cause mortality (p = 0.0084 and 0.0056, respectively), while no such association was found for intra-dialytic BPV or diastolic BPV. According to receiver operating characteristic curve with mortality as dependent variable, long-term SBP residual metric showed the strongest prognostic ability (area under curve [AUC] 0.679, p = 0.0006), which was even stronger in patients with BP ≥140/90 mm Hg (AUC 0.713, p = 0.0004). After completely adjusting for confounders, long-term SBP residual metric remained significantly associated with all-cause mortality (hazard ratio 1.628 per quartile; 95% CI 1.086–2.441). Conclusions: Our results suggest long-term SBP residual metric to be a better predictor of all-cause mortality in HD patients, which could be used as an additional target for BP management.

- Abstract
Purpose: This study assessed the effect of amoxicillin on outcomes in intensive care unit (ICU) patients with acute kidney injury (AKI), focusing on mortality rates and acute kidney disease (AKD) occurrence., Materials and Methods: We conducted a retrospective cohort analysis utilizing data from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database. The study included intensive care unit patients diagnosed with AKI to assess the effects of post-admission amoxicillin administration on 30-day and 90-day mortality rates and acute kidney disease incidence. We employed Cox proportional hazards models, propensity score matching, and inverse probability of treatment weighting to control for potential confounders., Results: Among 24,650 AKI patients, 676 (2.7%) received amoxicillin. The results indicated significantly lower mortality rates at 30 days (hazard ratio [HR] 0.54, 95% confidence interval [CI] 0.42-0.69) and 90 days (HR 0.64, 95% CI 0.52-0.77) in the amoxicillin group compared to non-recipients. Additionally, amoxicillin administration was associated with a reduced incidence of AKD (HR 0.49, 95% CI 0.36-0.65) but resulted in a modestly increased length of hospital stay (mean difference [MD] 1.95 days, 95% CI 1.15-2.75). A dose‒response relationship was evident, with higher doses (>875 mg) further decreasing mortality rates. Subgroup analysis revealed consistent benefits across most patient groups., Conclusion: Amoxicillin administration following ICU admission in patients with AKI was associated with improved survival rates and a lower incidence of AKD, highlighting its potential as a therapeutic measure for AKI management., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Luo, Zhou, Wan, Peng, Liao and Su.)

- Abstract
Objective: Tunneled-cuffed catheters (TCCs) are frequently used for establishing hemodialysis access for maintenance hemodialysis in older patients with exhausted resources of peripheral vessels. Fibrin sheath formation around the catheter is one of the most common complications of long-term use of indwelling catheter, which may cause the malfunction of the catheter. In this study, we intend to compare the prognosis of two catheter replacement methods, in situ replacement and replacement through a fibrin sheath crevice, with both being assisted by balloon dilation, and to explore the optimal catheter replacement process., Methods: A retrospective study was conducted with 52 patients who underwent a replacement of their TCCs. Among them, 27 cases had their TCC replaced by the modified method of replacement through a fibrin sheath crevice and were referred to as the sheath crevice group, while 25 cases underwent in situ catheter replacement and were referred to as the in situ group. The primary outcome indicators included maximum blood flow in hemodialysis catheter and the urea clearance rate calculated by Kt/V values at the 1, 3, and 6-month follow-ups. The secondary outcomes included dialyzer alarms being set off and catheter-related infections during follow-up., Results: There was no significant difference between the general data of the two groups. There was no massive blood loss during the replacement procedure. Neither were there cardiac tamponade, catheter-associated infections, or other complications. Follow-ups were made 1, 3, and 6 months after the replacement procedure. The sheath crevice group had higher catheter blood flow and Kt/V values at the 6-month follow-up than the in situ group did ([241.85±9.62] mL/min vs. [234.40±11.21] mL/min, P =0.014 and 1.31±0.55 vs. 1.27±0.49, P =0.005, respectively). During the follow-up process, access alarms were reported in 5 patients (three in the in situ group and two in the sheath crevice group) during dialysis. No catheter-associated infection occurred in either group., Conclusion: The catheter replacement method of balloon dilation-assisted catheter insertion through a fibrin sheath crevice is safe and effective, resulting in better long-term catheter blood flow compared with that of in situ catheter replacement., Competing Interests: 利益冲突 所有作者均声明不存在利益冲突, (© 2023《四川大学学报(医学版)》编辑部 版权所有Copyright ©2023 Editorial Board of Journal of Sichuan University (Medical Sciences).)

- Abstract
Background: Refractory peritonitis is one of the leading causes of catheter failure in peritoneal dialysis (PD) patients. However, there are no established curative therapies available, and only catheter removal should be performed. Here we present a case series study to illustrate the efficacy of antibiotic lock for PD-associated refractory peritonitis., Materials and Methods: Patients with refractory peritonitis treated with intraperitoneal antibiotics plus antibiotic lock from September 2020 to March 2022 were retrospectively analyzed. Medical cure was identified as a success of treatment., Results: We identified 11 patients, of which 7 (63.64%) had a history of PD-associated peritonitis, with the episode of continuous ambulatory peritoneal dialysis (CAPD) ranging from 1 to 158 months at a median of 36 (9.5, 50.5) months. The dialysis effluent culture showed Gram-positive, Gram-negative bacteria, and was culture-negative in 5, 2, and 4 cases, respectively. The cure rates were 85.71% for culture-positive cases and 25% for culture-negative cases, and the total cure rate was 63.64%. No relevant adverse events occurred, including sepsis., Conclusions: Treatment with the additional antibiotic lock was successful in most cases, especially in those that were culture-positive. Additional antibiotic lock deserves great attention and further investigation in treating PD-associated refractory peritonitis.
