Background And Objectives: Renal function has an important influence on the pharmacokinetics of vancomycin, and serum cystatin C (CysC) exhibits accurate predictive performance as a marker for renal function. This study aimed to develop a population pharmacokinetics (PopPK) model of vancomycin based on serum CysC in pediatric patients. In addition, vancomycin dosage was optimized with the area under the serum concentration-time curve over 24 h (AUC)/minimum inhibitory concentration (MIC) ratio in the target range of 400-700 and the steady-state trough concentration (C).
Methods: Data were retrospectively obtained from pediatric patients aged 2-18 years who received vancomycin treatment for infection from January 2014 to June 2019. PopPK analysis and Monte Carlo simulations were conducted using nonlinear mixed effects model (NONMEM) software.
Results: A total of 220 children were included. Serum CysC and age were significant covariates affecting the pharmacokinetics of vancomycin. The final typical value of clearance was 2.25 L/h; the volume of distribution was 8.17 L. The average probability of target attainment values of AUC/MIC ratios within 400-700 in the 2-7, 7-12, and 12-18 years age groups were 66.1%, 68.1% and 66.5%, respectively. The median C values of vancomycin for the 2-7, 7-12, and 12-18 years age groups were 7.49-11.84, 5.98-11.32, and 5.15-11.39 mg/L, respectively, and were highly correlated with AUC/MIC ratios in the range of 400-700 when the MIC was 1 mg/L.
Conclusions: The pharmacokinetic parameters for vancomycin in pediatric patients were estimated using a serum CysC model. The simulated dosages provide a reference for vancomycin therapy.

Cystatin C (Cys-C) is emerging as a critical biomarker for assess gestational diabetes mellitus (GDM), a condition that significantly impacts maternal and fetal health. In this study, we developed a novel label-free electrochemical immunosensor designed for point-of-care applications, offering lower reagent consumption and rapid detection of Cys-C in pregnant women with GDM. Compared to traditional enzyme-linked immunosorbent assays (ELISA), the sensor demonstrates enhanced sensitivity, reduced reagent usage, and faster detection.

Background: The impact of long-term renal function change on stroke outcomes remains unclear. This study used the CNSR-III (Third China National Stroke Registry) cohort to determine whether changes in estimated glomerular filtration rate based on creatinine and cystatin C (eGFR) during the first year post stroke were associated with 5-year stroke outcomes.
Methods And Results: We included 4270 patients with centrally tested serum creatinine and cystatin C at admission and 1 year post admission and evaluated 5-year follow-up data.

Aim: To evaluate the efficacy of flexible ureteroscopic lithotripsy (FURL) and extracorporeal shock wave lithotripsy (ESWL) in the treatment of ureteral calculi based on decision tree model.
Methods: A total of 600 patients with ureteral calculi, including 289 treated with FURL and 311 cases with ESWL in Anqing Municipal Hospital from June 2021 to August 2023, were selected as study subjects. Perioperative indicators and stone clearance rate of the two groups were compared, and the preoperative and postoperative (24 and 72 hours) changes of serum creatinine, cystatin C (Cys-C) and microalbumin were observed.
