A tribute to the late Professor Donald Simpson, Australian neurosurgeon and namesake of the Simpson grading system for meningioma extent of resection.
Donald Simpson (1927-2018) was a neurosurgeon from Adelaide, Australia, who is often cited for the 1957 publication he wrote as a trainee on the relationship between extent of resection and outcomes for meningiomas. That paper summarized a series of over 300 patients operated on in England by well-known neurosurgeons Sir Hugh Cairns and Joseph Buford Pennybacker. Simpson was also known later in his career, when he was at the University of Adelaide in South Australia, for his contributions to the areas of hydrocephalus, spina bifida, craniofacial anomalies, head injury, brain abscesses, and neurosurgical history, and he published extensively on these topics. ⋯ Simpson was an active member and leader of many Australian surgical organizations and was an officer of the Order of Australia. Donald Simpson's legacy as an adult and pediatric neurosurgeon, an academician, a leader, and a humanitarian is extensive and will prove long lasting. Professor Simpson's life serves as an example from which all neurosurgeons may learn.

ReviewAssessment of burnout prevention and wellness programs for US-based neurosurgical faculty and residents: a systematic review of the literature.
Neurosurgeon burnout is a serious and prevalent issue that has been shown to impact professionalism, physician health, and patient outcomes. Interventions targeting physician burnout primarily focus on improving physician wellness. Many academic neurosurgery programs have established wellness curricula to combat burnout and improve wellness. No official recommendations exist for establishing a wellness program that effectively targets sources of burnout. The aim of this review was to examine measures of burnout and report objective results of wellness interventions for neurosurgical faculty and residents. ⋯ Burnout among neurosurgical faculty and residents is prevalent and permeates the daily lives of neurosurgeons, negatively affecting patient outcomes, career satisfaction, and quality of life. Many neurosurgery programs have instituted wellness programs to combat burnout, but few have published evidence of improvement after implementation. While studies have shown that residents and faculty recognize the importance of wellness and look favorably on such initiatives, very few studies have reported objective outcomes.

Mechanical thrombectomy and intravascular imaging for cerebral venous sinus thrombosis: a preclinical model.
Although the majority of patients with cerebral venous sinus thrombosis (CVST) will improve with anticoagulation therapy, a portion of patients will either present in a comatose state or continue to deteriorate clinically despite early anticoagulation. In these cases, along with treating the underlying thrombophilia, timely thrombolysis may be beneficial. Repurposed arterial thrombectomy devices may not perform as expected in the cerebral venous sinus, and there are currently no preclinical endovascular thrombectomy (EVT) models for CVST. Contrary to arterial stroke research, preclinical models utilized to test various endovascular techniques and devices are lacking. The purpose of this research was to develop a reliable preclinical animal model for the testing of endovascular strategies to treat CVST. ⋯ The authors describe a preclinical model to assess endovascular techniques and devices for the treatment of CVST. Repurposed devices from arterial stroke may not perform as expected, given the unique features of venous sinus thrombosis. Residual bridging cortical vein thrombus and residual sinus thrombus, visualized on intravascular OCT, may be present despite complete sinus recanalization on angiography, and this may be the etiology of the poor clinical outcome despite technical success. In the setting of bridging cortical vein thrombus after successful sinus thrombectomy, direct chemical thrombolysis may be warranted to dissolve the remaining clot. This model may be helpful in developing and testing a new generation of devices designed specifically for CVST treatment.
