Studies of neurosurgical pediatric patients associate treatment at low-volume hospitals and by low-volume surgeons with increased odds of adverse outcomes. Although these associations suggest that increased centralization of care could be considered, we evaluate whether confounding endogenous factors mitigate against the proposed outcome benefits. ⋯ The literature consistently demonstrates a relationship between higher hospital and surgeon volume and better outcomes for pediatric neurosurgical patients. Of the 7 articles that assessed HF, only 2 analyses found that surgical volume remained associated with better outcomes. No reports assessed the degree of centralization already present. The call for centralization of pediatric care should be tempered until variables such as hospital factors, distribution of cases, and clinical thresholds can be defined and studied.

Endovascular treatment of ruptured intracranial aneurysms (rIAs) accompanied by intracerebral hematoma (ICH) can be challenging because the ICH can be enlarged due to intraoperative anticoagulation during the endovascular procedure. This retrospective study aimed to compare the outcomes of aneurysmal subarachnoid hemorrhage with and without ICH treated by endovascular procedures. ⋯ Endovascular treatment without hematoma evacuation did not adversely affect the outcomes of rIAs with ICH when the clinical condition and aneurysm morphology permitted. Surgical invasion might be avoidable with this less-invasive strategy without worsening the outcomes.

Preoperative anemia is known to be associated with perioperative complications in many surgical interventions. Here, we examine the effects of preoperative anemia on peri-operative complications and postoperative outcomes in pediatric patients undergoing spinal fusion. ⋯ Preoperative anemia leads to worse outcomes in pediatric spinal fusion procedures. Utilizing HCT recordings could be factored into the equation for optimal patient selection and prevention of post-operative complications.

A Systematic Review of The State of Neurosurgical Disparities Research: Past, Present, and Future.
The social determinants of health, which influence healthcare access, patient outcomes, and population-level burden of disease, contribute to health disparities experienced by marginalized patient populations. In the present study, we sought to evaluate the landscape of health disparities research within neurosurgery. ⋯ Although a recent increase has occurred in neurosurgical disparities research within the past decade, most studies were limited to the detection of disparities without understanding or evaluating any interventions for a reduction in disparities. Future research in neurosurgical disparities should incorporate the latter 2 factors to reduce disparities and improve outcomes for all patients.

Subarachnoid hemorrhage (SAH) is a cerebrovascular disorder with significant mortality and morbidity. Neural injury in SAH is mediated through a variety of pathophysiological processes. Currently available treatments are either nonspecific in targeting the basic pathophysiological mechanisms that result in neural damage in SAH, or merely focus on vasospasm. ⋯ Such agents have proven effective in ameliorating vasospasm, neural damage, and neurobehavioral outcomes in animal models of SAH. Human studies to test the safety and efficacy of intrathecal or parenteral administration of the inhibitors of ferroptosis in improving outcomes of SAH patients are warranted. There are currently a few ongoing clinical trials pursuing this therapeutic concept, the results of which will be critical to determine the value of ferroptosis as a novel therapeutic target in SAH.
