Emergency airway management in a Singapore centre: A registry study.

Introduction: Intubations in the emergency department (ED) are often performed immediately without the benefit of pre-selection or the ability to defer. Multicentre observational data provide a framework for understanding emergency airway management but regional practice variation may exist. We aim to describe the intubation indications, prevalence of difficult airway features, peri-intubation adverse events and intubator characteristics in the ED of the National University Hospital, Singapore.

Mesenchymal Stem Cell Exosomes for Cartilage Regeneration: A Systematic Review of Preclinical Studies.

Clinical and animal studies have demonstrated efficacy of mesenchymal stem/stromal cells (MSCs) in cartilage repair. Although MSCs were originally predicated to mediate tissue repair through cellular differentiation and cell replacement, it is now recognized that MSCs exert most of their paracrine effects on tissue repair through the release of extracellular vesicles (EVs). In particular, 50-200 nm small EVs that also include exosomes carry a rich cargo of lipids, nucleic acids, and proteins, and have been reported to be therapeutically efficacious in various disease indications, including osteochondral injuries and osteoarthritis (OA).
