Article Synopsis
  • Ascorbate (vitamin C) decreases the function of hematopoietic stem cells (HSCs) and helps prevent leukemia by enhancing the activity of the Tet2 tumor suppressor.
  • Deleting the Slc23a2 transporter from hematopoietic cells caused a significant drop in ascorbate levels within HSCs and multipotent progenitors (MPPs) but did not affect overall plasma ascorbate levels.
  • This deficiency led to increased reconstitution and self-renewal capabilities of HSCs and MPPs when transplanted into irradiated mice, particularly in their quiescent states, indicating that low ascorbate levels may enhance their long-term potential.

Ascorbate (vitamin C) limits hematopoietic stem cell (HSC) function and suppresses leukemia development by promoting the function of the Tet2 tumor suppressor. In humans, ascorbate is obtained from the diet while in mice it is synthesized in the liver. In this study, we show that deletion of the Slc23a2 ascorbate transporter severely depleted ascorbate from hematopoietic cells.

Introduction: Comprehensive data capture systems such as the Operating Room Black Box (OR Black Box) are becoming more widely implemented to access quality data in the complex environment of the OR. Prior to installing an OR Black Box, we assessed perceptions on safety attitudes, impostor phenomenon and privacy concerns around digital information sharing among healthcare professionals in the OR. A parallel survey was conducted in Canada, hence, this study also discusses cultural and international differences when implementing new technology in healthcare.

. The operating room (OR) Black Box is an innovative technology that captures and compiles extensive real-time data from the OR, allowing identification and analysis of factors that influence intraoperative procedures and performances - ultimately improving patient safety. Implementation of this kind of technology is still an emerging research area and prone to face challenges.

Article Synopsis
  • Play is a beneficial and low-cost intervention for pediatric patients in hospitals, helping them and their families cope with illness and hospitalization.
  • A scoping review analyzed 297 articles from the last 20 years, showing that play interventions are used by healthcare professionals for various purposes like pain management, education, and adaptation, mostly in high-income countries.
  • The findings suggest the need for further research on effective play principles and the long-term impacts of these interventions on child and family health in hospital settings.
