Two intracranial tumor volume variables have been shown to prognosticate survival of stereotactic-radiosurgery-treated brain metastasis patients: the largest intracranial tumor volume (LITV) and the cumulative intracranial tumor volume (CITV). ⋯ After accounting for covariates within the SIR model, CITV offers superior prognostic value relative to LITV for stereotactic radiosurgery-treated brain metastasis patients.

Women represent a growing cohort of US neurosurgeons. ⋯ Upon completion of training, 27% of women pursue fellowships. The distribution of women in private vs academic practice environments is proportionate to male neurosurgeons; however, the number women in academic leadership positions remains exceedingly low, with disproportionate representation in higher academic ranks. Women in national organized neurosurgery are increasing. Tracking the career paths of women in neurosurgery is a necessary step to identifying current achievements and opportunities for future progress.

Intracranial aneurysm rupture prediction is poor, with only a few risk factors for rupture identified and used in clinical practice. ⋯ Irregular aneurysm shape was identified as a risk factor with potential for use in clinical practice. The risk factors aspect ratio, size ratio, bottleneck factor, height-to-width ratio, contact with the perianeurysmal environment, volume-to-ostium ratio, and dome-direction should first be confirmed in multivariate analysis and incorporated in prediction models.

The benefit of surgical treatment of ruptured aneurysms is well established. ⋯ Ultra-early treatment of ruptured aneurysms is significantly associated with better discharge disposition and decreased hospitalization cost.

The costs and outcomes following degenerative spine surgery may vary from surgeon to surgeon. Patient factors such as comorbidities may increase the health care cost. These variations are not well studied. ⋯ Our study provides valuable insight into variations in 90-d costs among the surgeons performing elective lumbar laminectomy and fusion at a single institution. Specific surgeons were found to have greater odds of performing high-cost surgeries. Adjusting for preoperative comorbidities, however, led to costs that were higher than the actual costs for certain surgeons and lower than the actual costs for others. Patients' preoperative comorbidities must be accounted for when crafting value-based payment models. Furthermore, designing intervention targeting "modifiable" factors tied to the way the surgeons practice may increase the overall value of spine care.
