Surgeon attitudes toward risk stratification in emergency surgery for the elderly: an ESTES cross-sectional survey.

Purpose: Our study explores the utilization of objective tools for preoperative assessment of elderly patients by Emergency General Surgeons (EGS).

Methods: A descriptive cross-sectional survey was conducted via the European Society for Trauma and Emergency Surgery (ESTES) Research Committee. EGS were invited through the ESTES members' mailing list and social media platforms.

Mild acute biliary pancreatitis: still a surgical disease. A post-hoc analysis of the MANCTRA-1 international study.

Background: The current standard of care for mild acute biliary pancreatitis (MABP) involves early laparoscopic cholecystectomy (ELC) to reduce the risk of recurrence. The MANCTRA-1 project revealed a knowledge-to-action gap and higher recurrence rates in patients admitted to medical wards, attributable to fewer ELCs being performed. The project estimated a 35% to 70% probability of narrowing this gap by 2025.

Pulsed-Current Operation Enhances HO Production on a Boron-Doped Diamond Mesh Anode in a Zero-Gap PEM Electrolyzer.

A niobium (Nb) mesh electrode was coated with boron-doped diamond (BDD) using chemical vapor deposition in a custom-built hot-filament reactor. The BDD-functionalized mesh was tested in a zero-gap electrolysis configuration and evaluated for the anodic formation of HO by selective oxidation of water, including the analysis of the effects on Faradaic efficiency towards HO (FEH2O2) induced by pulsed electrolysis. A low electrolyte flow rate (V⋅) was found to result in a relatively high concentration of HO in single-pass electrolysis experiments.

Enhanced Photocatalytic Paracetamol Degradation by NiCu-Modified TiO Nanotubes: Mechanistic Insights and Performance Evaluation.

Anodic TiO nanotube arrays decorated with Ni, Cu, and NiCu alloy thin films were investigated for the first time for the photocatalytic degradation of paracetamol in water solution under UV irradiation. Metallic co-catalysts were deposited on TiO nanotubes using magnetron sputtering. The influence of the metal layer composition and thickness on the photocatalytic activity was systematically studied.

In Situ X-ray Absorption Spectroscopy Study of the Deactivation Mechanism of a Ni-SrTiO Photocatalyst Slurry Active in Water Splitting.

We used in situ X-ray absorption spectroscopy (XAS) to investigate the composition-performance correlation of Ni-SrTiO photocatalysts active for water splitting. After preparation and exposure to ambient conditions, the Ni particles on SrTiO consist of Ni(0) and Ni(II) phases, with a 4:1 at % ratio, in a metal/oxide core/shell configuration, as confirmed by XPS and TEM-EDX. In situ XAS experiments using an aqueous slurry of the Ni-SrTiO photocatalyst and simultaneous continuous exposure to 365 nm light with a power density of 100 mW cm and the X-rays do not reveal significant changes in oxidation state of the Ni particles.
