Staged endovascular and open surgical approach for treatment of a giant left upper back arteriovenous malformation.

We present a case of a symptomatic, giant, left upper back arteriovenous malformation that was treated through a staged endovascular and open approach. Through a series of embolizations, followed by resection, we were able to preserve the limb and upper back neurovascular supply, demonstrating an approach to preserve sensation and function and improving quality of life.

Deficiency of galactosyl-ceramidase in adult oligodendrocytes worsens disease severity during chronic experimental allergic encephalomyelitis.

Galactosyl-ceramidase (GALC) is a ubiquitous lysosomal enzyme crucial for the correct myelination of the mammalian nervous system during early postnatal development. However, the physiological consequence of GALC deficiency in the adult brain remains unknown. In this study, we found that mice with conditional ablation of GALC activity in post-myelinating oligodendrocytes were lethally sensitized when challenged with chronic experimental allergic encephalomyelitis (EAE), in contrast with the non-lethal dysmyelination observed in Galc-ablated mice without the EAE challenge.

Integrating Choosing Wisely, Value-Based Care Principles, Into Undergraduate Medical Education: A Pilot Study.

Background: Healthcare spending represents a large portion of the GDP of the United States. Value-based care (VBC) seeks to decrease waste in health care spending, yet this concept is insufficiently taught to medical students. The Choosing Wisely Students and Trainees Advocating for Resource Stewardship (STARS) campaign promotes initiatives that integrate knowledge of VBC into undergraduate medical education (UME).
