Fast Track Surgery-Minimizing Side Effects of Surgery

Current Advances of Atomically Dispersed Metal-Centered Nanozymes for Tumor Diagnosis and Therapy

Nanozymes, which combine enzyme-like catalytic activity and the biological properties of nanomaterials, have been widely used in biomedical fields. Single-atom nanozymes (SANs) with atomically dispersed metal centers exhibit excellent biological catalytic activity due to the maximization of atomic utilization efficiency, unique metal coordination structures, and metal-support interaction, and their structure-activity relationship can also be clearly investigated. Therefore, they have become an emerging alternative to natural enzymes. This review summarizes the examples of nanocatalytic therapy based on SANs in tumor diagnosis and treatment in recent years, providing an overview of material classification, activity modulation, and therapeutic means. Next, we will delve into the therapeutic mechanism of SNAs in the tumor microenvironment and the advantages of synergistic multiple therapeutic modalities (e.g., chemodynamic therapy, sonodynamic therapy, photothermal therapy, chemotherapy, photodynamic therapy, sonothermal therapy, and gas therapy). Finally, this review proposes the main challenges and prospects for the future development of SANs in cancer diagnosis and therapy.

[Post-polio Syndrome in the Perioperative Phase]

Due to the numerous poliomyelitis epidemics that have continued over the last decades and the post-polio syndrome (PPS) that occurs 10 - 30 years after poliomyelitis infection, the prevalence of PPS is also expected to increase in Europe. At the same time, due to the musculoskeletal disorders associated with the underlying disease, PPS patients often require surgery for which special anaesthetic requirements must be taken into account. In this analysis we summarise the current evidence and recommendations.
