Fueling the future of neurosurgery: increasing trends in female enrollment expanding the neurosurgical workforce from 2010 to 2019.

Objective: Regular reporting on recruitment of women into neurosurgery is a mechanism to track the progress of minority inclusion and diversity. For more than 20 years, half of US medical students have been women, yet a disproportionate minority pursue a career in neurosurgery. The authors previously published data tracking women in neurosurgery for the prior decade from 2000 to 2009, which showed an increasing match rate of women over time, from 18 women matched at the beginning of the decade to 36 matched at the end.

Blunt Cerebrovascular Injury: Are We Overscreening Low-Mechanism Trauma?

Background And Purpose: Screening patients with trauma for blunt cerebrovascular injury with neck CTA is a common practice, but there remains disagreement regarding which patients should be screened. We reviewed adult blunt cerebrovascular injury data from a level 1 trauma center to investigate whether screening is warranted in low-mechanism trauma.

Materials And Methods: We reviewed all neck CTAs performed on adult trauma patients in the emergency department during the 2019 calendar year.

Evaluation of Deep Brain Stimulation (DBS) Lead Biomechanical Interaction with Brain Tissue.

The current study aims to examine the effect of material properties on implanted leads used for deep brain stimulation (DBS) using finite element (FE) analysis to investigate brain deformation around an implanted DBS lead in response to daily head accelerations. FE analysis was used to characterize the relative motion of the DBS lead in a suite of fifteen cases sampled from a previously derived kinematic envelope representative of everyday activities describing translational and rotational pulse shape, magnitude, and duration. Load curves were applied to the atlas-based brain model (ABM) with a scaled Haversine acceleration pulse in four directions of rotation: + X, - Y, + Y, and + Z.

Pilot characterization of head kinematics in grassroots dirt track racing.

Objective: The objective of this study was to utilize an instrumented mouthpiece sensor to characterize head kinematics experienced by grassroots dirt track race car drivers.

Methods: Four dirt track race car drivers (ages 16-19) were instrumented with custom mouthpiece sensors capable of accurately measuring head motion during racing. Sensors were deployed before races and recorded tri-axial linear acceleration and rotational velocity for approximately 10 min at 200 Hz.
