As professionals who care for the sickest children, we want to provide the best evidence-based care available. While there are questions still to be answered, it is clear that when propofol is administered to children, it should be done in a manner that is intentional, well planned, and consistent with national guidelines and regulatory groups. Haphazard administration of propofol will place children at risk.

Data collection from all referred patients allows continuous learning and improvement of services. Patient safety and return for cancer therapy takes priority in all oncofertility services. In certain cases, the intervention for female patients is contraindicated and, aside from extensive counseling, alternative methods of preserving fertility should be explored.

The physical microenvironment plays a crucial role in tumor development, progression, metastasis and treatment. Recently, we proposed four physical hallmarks of cancer, with distinct origins and consequences, to characterize abnormalities in the physical tumor microenvironment: (1) elevated compressive-tensile solid stresses, (2) elevated interstitial fluid pressure and the resulting interstitial fluid flow, (3) altered material properties (for example, increased tissue stiffness) and (4) altered physical micro-architecture. As this emerging field of physical oncology is being advanced by tumor biologists, cell and developmental biologists, engineers, physicists and oncologists, there is a critical need for model systems and measurement tools to mechanistically probe these physical hallmarks.

The pangenome of a species is the set of all genes carried by at least one member of the species. In bacteria, pangenomes can be much larger than the set of genes carried by a single organism. Many questions remain unanswered regarding the evolutionary forces shaping the patterns of presence/absence of genes in pangenomes of a given species.

The question of whether scuba diving is safe for patients with a history of venous thromboembolism (VTE) remains unanswered. Cases of VTE have been reported after decompression accidents but not following properly conducted dives. However, the risk of VTE and bleeding on anticoagulant therapy during diving has yet to be defined.

The cell membrane, characterized by its inherent asymmetry, functions as a dynamic barrier that regulates numerous cellular activities. This Highlight aims to provide the chemistry community with a comprehensive overview of the intriguing and underexplored inner leaflet, encompassing both fundamental biology and emerging synthetic modification strategies. We begin by describing the asymmetric nature of the plasma membrane, with a focus on the distinct roles of lipids, proteins, and glycan chains, highlighting the composition and biofunctions of the inner leaflet and the biological mechanisms that sustain membrane asymmetry.
