Cisplatin, a frontline chemotherapeutic agent against cancer, faces challenges in clinical application due to significant toxicities and suboptimal efficacy. Renal toxicity, a dose-limiting factor of cisplatin, results from multifactorial processes including cisplatin-induced cellular pyroptosis, oxidative damage, and inflammatory responses. Our findings reveal that Tea Polyphenols Nanoparticles (TPNs) derived from Epigallocatechin gallate (EGCG) effectively could address these diverse mechanisms, comprehensively alleviating cisplatin-induced nephrotoxicity. Leveraging TPNs as carriers, chemical conjugation enables the encapsulation of tetravalent cisplatin prodrug, extending its systemic half-life, enhancing tumor tissue accumulation, while simultaneously mitigating renal toxicity. Concurrently, employing a CRISPR/Cas9 kinase library, we identified CSNK2A1 as a target sensitizing tumor cells to cisplatin, enabling specific siRNA sequences to augment cisplatin susceptibility, thereby minimizing the dosage requirement. Benefiting from the versatile carrier properties of TPNs to codeliver cisplatin prodrug and anti-CSNK2A1 siRNA, we developed a codelivery system, Pt-TPNs/siRNA. Pt-TPNs/siRNA not only enhances the anticancer effects but also mitigates cisplatin-induced renal toxicity, achieving efficacy while reducing toxicity. Mechanistic and safety assessments of these nanoparticles were conducted at both cellular and animal levels, opening new avenues for improved clinical utilization of cisplatin.

Vascular calcification significantly increases the incidence of cardiovascular disease and all-cause mortality patients with chronic kidney disease(CKD), severely affecting their health and lifespan. However, the mechanisms underlying vascular calcification in CKD remain incompletely understood, and the available therapeutic agents are limited. Research has found that the transformation of vascular smooth muscle cells(VSMCs) from a contractile phenotype to an osteoblast-like phenotype is a key step in CKD-related vascular calcification.

The effect of the aqueous extract of (AAI) on gentamicin (GEN)-induced kidney injury was investigated. The study involves 20 adult male Wistar rats (housed in four separate plastic cages) such that graded dosages of AAI were administered to the experimental group for 14 days per oral (PO) before exposure to GEN toxicity (100 mg/kg) for 1 week. At the end of the study, comparisons of some markers of renal functions, antioxidant status, and inflammatory and apoptotic markers were made between the control, GEN, and AAI-pretreated groups at < .

Background: In the fifth National Wilms Tumor Study, patients received vincristine and dactinomycin (VA) without radiation for stage I focal anaplastic Wilms tumor (FAWT) and VA plus doxorubicin (DD4A) and radiation for stage II-IV FAWT. Four-year event-free survival (EFS) and overall survival (OS) for stage I FAWT were 67.5% and 88.

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a group of autoimmune diseases primarily cause inflammation of small blood vessels. Renal involvement occurs frequently and often leads to end-stage renal disease (ESRD), which significantly impacts patient health and survival. Early diagnosis and appropriate treatment are essential to improving patient outcomes.

Background: Myoclonus is a hyperkinetic movement with various attributable etiologies, semiologies, and treatment outcomes. To our knowledge, few studies investigated adult-onset myoclonus in an inpatient setting.
Methods: We retrospectively reviewed charts of adult inpatients with myoclonus at New York Presbyterian Brooklyn Methodist Hospital between 2011 and 2021.
