Prostate tumour cells release small extracellular vesicles or exosomes which are taken up by target cells and can potentially facilitate tumour growth and metastasis. The present work studies the effect of exosomes from cell lines that are representative of the different stages of the disease on the tumoral phenotype of PC3 cells.

Article Synopsis
  • Despite clinical guidelines recommending lower use of central venous catheters (CVC), the prevalence remains high among patients undergoing hemodialysis, leading researchers to explore whether this is due to unavoidable circumstances or factors that can be addressed.
  • A study involving 637 chronic hemodialysis patients from various centers in Spain sought to identify modifiable factors influencing CVC use, comparing demographics, vascular access types, and reasons patients had for not using arteriovenous fistulas (AVF).
  • Results showed that 40% of the patients utilized CVCs, with major reasons for CVC use including patient refusal for surgery (often due to fear) and having initiated hemodialysis with a CVC, indicating that
