Contemporary cohort of cerebral cavernous malformations: natural history and utility of follow-up MRI.
This study reports the natural history of cerebral cavernous malformations (CCMs) in a contemporary cohort with prospectively collected data from multiple sources, access to follow-up imaging, integrated electronic medical records, and detailed imaging review by study investigators. The authors aimed to define the first prospective symptomatic hemorrhage (SH) and severe SH rates, determine the risk of a second prospective SH, and identify risk factors for SH. ⋯ In a contemporary cohort of adult patients with CCM, the authors report 5-year SH and severe SH rates, rates of second prospective hemorrhage, and predictors of SH. Persistent or new hyperintensity on T1-weighted MRI may be a useful marker of disease activity.

How the elastase-induced rabbit aneurysm heals following flow diverter treatment: a histopathological study.
Fibrin deposition is integral to thrombus formation and wound healing. The role of fibrin deposition and subsequent metabolism following flow diversion for aneurysm treatment remains poorly characterized. This study aimed to evaluate the role of fibrin in early thrombus organization after flow diverter treatment. ⋯ These findings indicate that fibrin plays a foundational role in the gradual occlusion of aneurysms after flow diverter treatment. Endovascular approaches that enhance fibrin accumulation could potentially improve aneurysm occlusion rates. Further research is needed to establish the precise role of fibrin in aneurysm occlusion.

Development and validation of a novel nomogram for predicting good neoangiogenesis after encephaloduroarteriosynangiosis in patients with moyamoya disease and type 2 diabetes mellitus: a case-control study.
Diabetes is often linked to poorer outcomes in patients with moyamoya disease (MMD). However, experience has shown that certain individuals with diabetes have favorable outcomes after encephaloduroarteriosynangiosis (EDAS). The authors aimed to develop a nomogram to predict good neoangiogenesis in patients with MMD and type 2 diabetes mellitus (T2DM) to aid neurosurgeons in the identification of suitable candidates for EDAS. ⋯ The nomogram developed in this study accurately predicted neoangiogenesis in patients with MMD and T2DM after EDAS and may assist neurosurgeons in identifying suitable candidates for indirect revascularization surgery.

Introducing a novel hybrid educational boot camp to augment medical student training in neurosurgery.
Neurosurgery subinternships are a critical portion of the medical student application to neurosurgery residency programs, allowing programs to assess the student's clinical knowledge, interpersonal skills, work ethic, and character. Despite how critical these auditions are, many students have a poor understanding of expectations prior to beginning these subinternships. Thomas Jefferson University hosted a combined in-person and virtual boot camp session open to all medical students interested in neurosurgery. The authors sought to determine the effectiveness of this inaugural course. ⋯ The boot camp successfully delineated the expectations of neurosurgery subinterns and enhanced the attendees' confidence in their abilities. The authors concluded that a hybrid virtual and in-person format is beneficial and feasible in increasing accessibility to information about neurosurgery subinternships.
