The incidence and temporal trend of appendicitis in children: An analysis from the Global Burden of Disease Study 2021.

Background: Challenges persist in the management of appendicitis in children, but its incidence and temporal trends have been reported in only a few developed countries. This study aimed to comprehensively investigate the incidence and temporal trends of appendicitis in children at the global, regional, and national levels, providing evidence for implementing and scaling up intervention services to reduce adverse health outcomes.

Methods: This study downloaded incidence data on appendicitis in children from the Global Burden of Disease 2021.

Biocompatible, biodegradable, and anticancer alginate-quercetin ureteral stent via co-axial extrusion technique.

Ureteral stents (US) are used as interventional medical implants in the treatment and surgery of urinary tract infections (UTIs). This study reported a new formulation of alginate-quercetin (AQ) based US through a co-axial extrusion procedure for the first time to afford a 26 cm long US with 3.2×1.

Recyclable Amphiphilic Magnetic-responsive Mixed-Shell Nanoparticles With High Interfacial Activity Comparable to Janus Particles for Oily Water Purification.

Amphiphilic magnetic-responsive mixed-shell nanoparticles (Mag-MSNPs) with tailorable compositions are synthesized by electrostatic-mediated cross-linking of core-forming blocks of two diblock copolymers, followed by in situ growth of magnetite in the cross-linked core. The Mag-MSNPs have a magnetic-responsive core and hydrophilic/lipophilic mixed shells, firmly anchoring at the oil-water interface of emulsified oil droplets due to their high interfacial activity (13.1 mN m at a rather low emulsifier concentration of 1.

TQB2450 with or without anlotinib as maintenance treatment in subjects with locally advanced/unresectable non-small cell lung cancer that have not progressed after prior concurrent/sequential chemoradiotherapy (R-ALPS): study protocol for a randomized, double-blind, placebo-controlled, multicenter phase III trial.

Background: Immune checkpoint inhibitors (ICIs) have revolutionized the treatment of non-small cell lung cancer (NSCLC). TQB2450 (benmelstobart) is a novel humanized immunoglobulin G1 monoclonal antibody against programmed death-ligand 1 (PD-L1). Anlotinib, an oral multitargeted anti-angiogenic agent with potential synergy with ICIs, has shown efficacy in relapsed and advanced NSCLC.

Arsenic Reduces Methane Emissions from Paddy Soils: Insights from Continental Investigation and Laboratory Incubations.

Arsenic (As) contamination and methane (CH) emissions co-occur in rice paddies. However, how As impacts CH production, oxidation, and emission dynamics is unknown. Here, we investigated the abundances and activities of CH-cycling microbes from 132 paddy soils with different As concentrations across continental China using metagenomics and the reverse transcription polymerase chain reaction.
