Memory deficits are considered to have a great influence on self-management, dietary restriction and therapeutic regimen for end-stage renal disease (ESRD) patients with dialysis treatment. This study was aim to investigate the spontaneous brain activity and its relationship with memory performance in ESRD patients before dialysis (T1) and after 24 h (T2) during a single dialysis session. 23 ESRD patients and 25 matched healthy controls (HCs) were scanned using functional magnetic resonance imaging (fMRI) at T1, and all patients were also scanned at T2. Amplitude of low-frequency fluctuation (ALFF) and regional homogeneity (ReHo) methods were used to evaluate the spontaneous brain activity between two groups. The Auditory Verbal Learning Test-Huashan version (AVLT-H) was performed to assess memory function. Compared with HCs, ESRD group showed a significant decreases in the immediate recall total score (IR-S), short-term delayed recall score (SR-S), and long-term delayed recall score (LR-S) at T1. IR-S, SR-S, LR-S and recognition score (REC-S) were significantly increased at T2. Compared with HCs at T1, ESRD patients showed that the lower mean ALFF (mALFF) values were mainly located in dorsolateral prefrontal cortex (DLPFC), medial frontal gyrus, and precuneus. Higher ReHo in the bilateral inferior temporal gyrus and left hippocampus and lower ReHo in the right precentral gyrus, anterior cingulate cortex were found at T1 too. The mALFF values of the DLPFC and precuneus were significantly increased during a dialysis session, while no significantly difference of ReHo region was found. Furthermore, the increased mALFF values of the DLPFC were significantly positively correlated with the improvement in the IR-S. Our results indicated that increased regional spontaneous activity of the DLPFC may reflect memory performance improvement after a single dialysis treatment, which may provide insight into the effect of hemodialysis on spontaneous brain function during a single dialysis session.

Objective: Catheter-related thrombosis is a common complication of central venous catheter insertion. As the use of central venous catheters increases in pediatric critical care settings, catheter-related thrombosis is becoming more common among patients who typically have multiple risk factors for thromboembolism. We aimed to investigate impact of catheter-to-vein diameter ratio on thrombosis in pediatric central venous catheterization.

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.

The global burden of kidney disease displays marked sexual dimorphism. Lineage tracing and single-cell RNA-sequencing revealed that starting from puberty, estrogen signaling in female mice supports self-renewal and differentiation of renal progenitors to increase filtration capacity, reducing sensitivity to glomerular injury compared with that of males. This phenomenon accelerated as female kidneys adapted to the workload of pregnancy.

Purpose: To identify ocular manifestations of vitamin A deficiency in a case series of patients presenting with keratopathy at a tertiary care center of a high-income country, and to highlight clinical features and treatment outcomes.
Methods: A retrospective chart review was conducted of patients diagnosed with xerophthalmia at as single institution between January 1, 2025, and May 31, 2025. Patients were identified using diagnostic codes for xerophthalmia and related ocular surface disease.
