The impact of race, socioeconomic status (SES), insurance status, and other social metrics on the outcomes of patients with intracranial tumors has been reported in several studies. However, these findings have not been comprehensively summarized. ⋯ Significant disparities exist among patients with intracranial tumors, particularly affecting patients of African American race and lower SES. Efforts at the hospital, state, and national level must be undertaken to identify root causes of these issues.

Surgical management of aneurysmal subarachnoid hemorrhage (SAH) often involves red blood cell (RBC) transfusion, which increases the risk of postoperative complications. RBC transfusion guidelines report on chronically critically ill patients and may not apply to patients with SAH. Our study aims to synthesize the evidence to recommend RBC transfusion thresholds among adult patients with SAH undergoing surgery. ⋯ Among patients with SAH, the benefits of reducing cerebral ischemia and anemia are shown to outweigh the risks of transfusion-related complications.

Myxopapillary Ependymoma with Anaplastic Features: a case series and review of the literature.
Myxopapillary ependymomas (MPEs) with anaplastic features are rarely reported, with only 21 cases identified to date, and long-term recurrence is rarely presented. A case series is presented to expand understanding of this disease by describing 3 unique cases, including 2 that arose from MPE after a prolonged clinical course. ⋯ The presented cases of MPE with anaplastic features make a total of 24 cases on record in the medical literature and demonstrate 2 examples of late recurrence.

The role of cerebral pressure autoregulation (CPA) in brain injury and disorders has gained increased interest. The CPA is often disturbed as a consequence of acute brain injury, which contributes to further brain damage and worse outcome. Specifically, in severe traumatic brain injury, CPA disturbances predict worse clinical outcome and targeting an autoregulatory-oriented optimal cerebral perfusion pressure threshold may improve brain energy metabolism and clinical outcome. ⋯ In spontaneous intracerebral hemorrhage, the role of autoregulatory disturbances is less clear, but CPA disturbances correlate with worse clinical outcome. Also, in community-acquired bacterial meningitis, CPA dysfunction is frequent and correlates with worse clinical outcome, but autoregulatory management is yet to be evaluated. In this review, we discuss the role of CPA in different types of brain injury and disease, the strengths and limitations of the monitoring methods, the potentials of autoregulatory management, and future directions in the field.

As many as 30% of patients with non-small cell lung cancer (NSCLC) will develop brain metastases (BMs) over the course of their illness. Here, we quantitatively compare the efficacy of the various emerging regimens for NSCLC BMs without a definitive targetable epidermal growth factor receptor mutation/ALK rearrangement. ⋯ In this network meta-analysis, we demonstrate the promising survival benefit with use of checkpoint inhibitor-based regimens in NSCLC BMs without a targetable epidermal growth factor receptor mutation/ALK rearrangement. Moving forward, large-scale BM-focused RCTs are necessary to establish the iPFS benefit of immune checkpoint inhibitor-based immunotherapy in this patient population.
