Article Abstract
Background: Sepsis is defined as a dysregulated host response to infection that results in life-threatening organ dysfunction. The 24-hour urine volume plays a crucial role in assessing the prognosis of septic patients. This study aims to investigate the relationship between 24-hour urine volume and 28-day intensive care unit (ICU) mortality in septic patients and exploring the dose-response relationship between these variables.
Methods: This retrospective cohort study analyzed data from 7,218 sepsis patients in the eICU Collaborative Research Database. Logistic regression models and generalized additive models were used to examine the relationship between 24-hour urine volume and 28-day ICU mortality.
Results: A negative correlation was found between 24-hour urine volume and ICU 28-day mortality. In the fully adjusted model, each 50 mL increase in 24-hour urine volume significantly reduced mortality risk by 1% (OR = 0.99, 95% CI = 0.98-0.99, < 0.001). A nonlinear dose-response relationship was observed, with an inflection point at ~1,663.5 ml. Below this threshold, increased urine volume was significantly associated with reduced mortality risk (OR = 0.97, 95% CI: 0.96-0.98, < 0.001), while above this point, the relationship was not statistically significant.
Conclusion: This study demonstrates a non-linear negative correlation between 24-hour urine volume and 28-day ICU mortality in sepsis patients.

Transition to a combination of peritoneal dialysis and hemodialysis in chronic kidney disease patients receiving peritoneal dialysis treatment: a single-center study.

Peritoneal dialysis (PD) and hemodialysis (HD) are the two primary renal replacement therapies for patients with end-stage renal disease (ESRD). While PD is an effective and convenient modality, long-term use can lead to ultrafiltration failure, recurrent peritonitis, and progressive structural alterations in the peritoneal membrane, necessitating a transition to HD. In recent years, rather than a complete transition, the combined use of PD and HD has emerged as a viable alternative, offering potential advantages for selected patient populations.

Background: This study characterized the urinary pharmacokinetics and pharmacodynamics (PK/PD) of linezolid (LNZ) in critically ill patients with renal impairment and nosocomial multidrug-resistant Gram-positive urinary tract infections (UTIs). The aim was to address therapeutic challenges arising from limited treatment options and uncertain urinary excretion, to establish optimized dosing strategies.
Methods: A prospective observational study was conducted in ICU patients with renal impairment.

Synthetic cathinones (SCs) are drugs of abuse that act on the central nervous system, producing psychoactive effects similar to those of amphetamines. Their greater accessibility compared with the traditional amphetamine-type stimulants has contributed to their increasing popularity in recent years. The analysis of SCs in biological samples is essential for documenting their consumption.

Objective: Traditional Chinese medicine exhibits positive therapeutic effects as a primary or adjunctive treatment for diabetic nephropathy (DN). This study aimed to evaluate the impact and mechanism of action of Xiaoke decoction (XKD), a traditional Chinese medicine, on renal function in DN rats.
Methods: A rat model of DN was established, and the rats were divided into five groups (n = 7 per group): normal control group (NC), DN model group (DN), low-dose XKD treatment group (DN + XKD-L, 1.

Objective： To investigate the effects of 3D laparoscopic radical resection prostatectomy(LRP) on urinary control and sexual function of patients with prostatic cancer. Methods： A total of 268 patients who were treated with LRP in the Fifth People's Hospital of Huai'an City from January 2019 to May 2022 were selected and divided into 2 groups according to surgical methods, with 134 cases in each group. The patients in the control group were treated with traditional LRP, and the 3D LRP was used in the observation group.
