Defining and responding to the contextual drivers for implementation of antimicrobial stewardship in 14 neonatal units in South Africa.

Background: Research on the contextual drivers of antimicrobial stewardship (AMS) programme interventions in neonatal units is limited.

Methods: As part of a prospective mixed-methods multidisciplinary neonatal AMS (NeoAMS) interventional study in 14 South African hospitals, we applied a three-phased process to assess implementation barriers and contextual drivers experienced by participating health professionals. The study included: (Phase one; P1) a survey of pre-intervention barriers and enablers; (P2) written feedback during the study intervention phase; and (P3) semi-structured exit interviews.

Integrating immunity, antioxidative status, and gene regulation against nickel and high-temperature stress in fish: selenium nanoparticles for mitigation.

Fish face health hazards due to high-temperature (T) stress and the toxicity associated with nickel (Ni), both of which can occur in aquatic ecosystems. The accumulation of nickel in fish may pose risks to human health when contaminated fish are consumed. Consequently, the goal of this study was to clarify how selenium nanoparticles (Se-NPs) help Pangasianodon hypophthalmus by reducing the effects of nickel and high-temperature stress.

BRAF inhibitor monotherapy in BRAFV600E-mutated pediatric low-grade glioma: a single center's experience.

Background: Pediatric low-grade gliomas (pLGGs) have an overall survival of over 90%; however, patients harboring a BRAF alteration may have worse outcomes, particularly when treated with classic chemotherapy. Combined BRAF/MEK inhibition following incomplete resection demonstrated improved outcome in BRAF altered pLGG compared to combined carboplatin/vincristine chemotherapy and is now considered the standard FDA-approved treatment for this group of tumors. The aim herein was to investigate the efficacy and tolerability of single agent BRAF inhibitor treatment in BRAF altered pLGG.
