Blood pressure variability (BPV) has been shown to correlate with poor outcomes in patients with intracerebral hemorrhage (ICH) and traumatic brain injury. However, this association has not been elucidated in patients with traumatic cervical spinal cord injury (cSCI). We hypothesized that 24-hour BPV from time of admission is associated with worse outcomes in patients with cSCI. ⋯ BPV during the first 24 hours after injury in patients with traumatic cSCI was independently associated with poor functional outcome at 3 months. Stabilization of BPV during the hyperacute and acute period may be a therapeutic target to improve functional outcomes of these patients.

Review Meta Analysis
Effects of miRNA-modified exosomes alleviate cerebral ischemic reperfusion injury in Pre-clinical Studies: A Meta-analysis.
Cell-derived exosomes bearing microRNAs (miRNAs) have emerged as a potential therapeutic option for cerebral ischemia-reperfusion injury (CIRI). However, their mechanism of action and clinical translation value remain unclear. The present meta-analysis investigated the therapeutic effects of miRNA-modified exosomes used in preclinical animal models of CIRI. ⋯ miRNA-modified exosomal therapy demonstrated the potential to improve infarct volume and neurobehavioral performance in preclinical animal models of CIRI. Despite the heterogeneity among studies, the results may provide some direction for future clinical research.

Meta Analysis
Prolonged Opioid Use After Lumbar Fusion Surgery: A Meta-Analysis of Prevalence and Risk Factors.
Persistent opioid utilization after spine surgery is a rising complication among both preoperatively opioid-naïve and opioid-tolerant patients. To our knowledge, this is the first meta-analysis to determine the prevalence and characterize the risk factors that predispose patients to prolonged opioid use (≥3 months) after lumbar fusion. ⋯ The high prevalence of prolonged opioid use after lumbar fusion underscores the importance of screening patients for comorbidities and implementing targeted strategies to minimize opioid misuse.

Multicenter Study
International Survey of Antiseizure Medication Use in Patients with Complicated Mild Traumatic Brain Injury: A New York Neurotrauma Consortium Study.
Seizures and epilepsy after traumatic brain injury (TBI) negatively affect quality of life and longevity. Antiseizure medication (ASM) prophylaxis after severe TBI is associated with improved outcomes; these medications are rarely used in mild TBI. However, a paucity of research is available to inform ASM use in complicated mild TBI (cmTBI) and no empirically based clinical care guidelines for ASM use in cmTBI exist. We aim to identify seizure prevention and management strategies used by clinicians experienced in treating patients with cmTBI to characterize standard care and inform a systematic approach to clinical decision making regarding ASM prophylaxis. ⋯ This study is the first to characterize factors influencing clinical decision making in ASM prophylaxis after cmTBI based on multidisciplinary multicenter provider practices. Prospective controlled studies are necessary to inform standardized guideline development.

In this era of imagination and technological innovation, mixed reality systems such as virtual reality (VR) and augmented reality (AR) are contributing to a wide array of neurosurgical care, from the betterment of surgical planning and surgical comfort to novel treatments and improved resident education. These systems can augment procedures that require high-level dexterity such as minimally invasive surgery and tumor excisions, as well as peripheral and neurovascular surgery. We define and compare the technological features, indications, and characterized outcomes of VR and AR systems in the context of neurosurgery through a review of the literature to date. Moreover, this review discusses the limitations of VR and AR and includes an overview of the cost-effectiveness of each of these systems. ⋯ This literature review examines recent research into VR and AR applications in neurosurgical care. The literature establishes that there are technological features, indications, outcomes, limitations, and cost-effectiveness differences between these systems. Based on ongoing and evolving applications of the VR and AR systems, the innovative potential that they make available to the future of neurosurgical patient care makes clear the need for further studies to understand the nuances between their differing technological advances.
