Background: Deep neck space infections (DNSI) are common, potentially life-threatening presentations in otolaryngology. Treatment is often based on the severity of presenting symptoms and surgeon preference. This study aims to evaluate the presentation and predictors of complications in patients presenting with DNSI at an Australian Otolaryngology referral centre.

Introduction: Increased aggression in a regional Comprehensive Psychiatric Emergency Program (CPEP) led to a significant rise in physical assaults, restraints, and use of security personnel. Root cause analysis revealed a need for more extensive training on de-escalation, teamwork and communication.

Aims: This quality improvement project evaluated the impact of an interprofessional, high-fidelity simulation project on interdisciplinary collaboration to manage de-escalation and aggression safely and effectively.

Photocatalytic C-H activation is an emerging area of research. While cerium chloride photocatalysts have been extensively studied, the role of alcohol additives in these systems remains a subject of ongoing discussion. It was demonstrated that the photocatalyst [NEt][CeCl] () produces •Cl and added alcohols exhibit zero-order kinetics.

Hydrogen atom transfer (HAT) processes provide an important strategy for selective C-H functionalization. Compared with the popularity of 1,5-HAT processes, however, net-1,2-HAT reactions have been reported less frequently. Herein, we report a unique visible-light-mediated net-1,2-HAT of amidyl radicals for the synthesis of β-amido ketone derivatives.

Unlabelled: Chronic pain is a major global health issue, yet effective treatments are limited by poor translation from preclinical studies to humans. To address this, we developed a high-content screening (HCS) platform for analgesic discovery using hiPSC-derived nociceptors. These cells were cultured on multi-well micro-electrode arrays to monitor activity, achieving nearly 100% active electrodes by week two, maintaining stable activity for at least two weeks.
