Extracellular vesicles (EVs) are membrane-bound structures produced and released into the extracellular space by all types of cells. Due to their characteristics, EVs play crucial roles in cellular communication and signaling, holding an immense potential as biomarkers and molecular transporters. Various methods have been developed to label and characterize EVs, however, visualizing EVs remains a process that requires highly specialized and expensive equipment, which is not always available in all the laboratories.

Spine surgery is highly litigious; misplaced screws and intraoperative neuromonitoring frequently feature in lawsuits. Intraoperative neuromonitoring aims to prevent injury but its standards are debated, and literature suggests its benefits are mixed. We surveyed its use among neurosurgeons from the Congress of Neurological Surgeons with Pearson's chi-square test applied to analyse data within R.
