Comparative analysis of cold-stored apheresis platelet units in additive solution with or without pathogen reduction: Implications of cytochrome c supplementation.

Background: Platelets are limited in supply, and the preservation of platelet function during storage remains challenging. Novel storage approaches are being explored to improve platelet quality, extend shelf life, and reduce risk of infection. This study sought to elucidate platelet function in cold-stored apheresis units in additive solution (platelet additive solution [PAS]) and subjected to pathogen reduction (PR) as well as the impact of cytochrome c (cyt c) supplementation.

The dispersion method does not affect the in vitro genotoxicity of multi-walled carbon nanotubes despite inducing surface alterations.

Multi-walled carbon nanotubes (MWCNTs) are a desirable class of high aspect ratio nanomaterials (HARNs) owing to their extensive applications. Given their demand, the growing occupational and consumer exposure to these materials has warranted an extensive investigation into potential hazards they may pose towards human health. This study utilised both the in vitro mammalian cell gene mutation and the cytokinesis-blocked micronucleus (CBMN) assays to investigate genotoxicity in human lymphoblastoid (TK6) and 16HBE14o human lung epithelial cells, following exposure to NM-400 and NM-401 MWCNTs for 24 h.

Outcomes, mortality risk factors, and functional status post-Norwood: A single-center study.

Background: The Norwood operation (NO) for infants with univentricular physiology has high interstage mortality. This study evaluated outcomes and risk factors for mortality following NO.

Methods: Retrospective single-center study of patients undergoing NO from 2010 to 2020.

Genomic Biomarkers Associated with Enfortumab Vedotin Outcomes for Patients with Advanced Urothelial Carcinoma: Analysis of UNITE Study Data.

Enfortumab vedotin (EV) is used as monotherapy or combined with pembrolizumab in advanced urothelial carcinoma (aUC), but biomarker data associated with EV outcomes are limited. We identified 170 patients in the UNITE study who received EV monotherapy and had molecular biomarker data available. Outcomes for groups with and without a particular biomarker were compared using logistic regression (unadjusted) for the objective response rate (ORR), and a log-rank test and Cox proportional-hazard models (CPHMs) for progression-free survival (PFS) and overall survival (OS) from EV initiation.

Determining the association of hyperoxia while on extracorporeal life support with mortality in neonates following Norwood operation.

Background: Patients requiring extracorporeal life support (ECLS) support post-Norwood operation constitute an extremely high-risk group.

Materials And Methods: We retrospectively aimed to evaluate the relationship of hyperoxia with mortality and other clinical outcomes in patients who required ECLS following Norwood operation between January/2010 and December/2020 in a large volume center.

Results: During the study period 65 patients required ECLS post-Norwood.
