Outcome of stereo-electroencephalography with single-unit recording in drug-refractory epilepsy.
The aim of this study was to evaluate the utility and safety of "hybrid" stereo-electroencephalography (SEEG) in guiding epilepsy surgery and in providing information at single-neuron levels (i.e., single-unit recording) to further the understanding of the mechanisms of epilepsy and the neurocognitive processes unique to humans. ⋯ Hybrid SEEG enables safe and effective localization of epileptogenic zones to guide epilepsy surgery and provides unique scientific opportunities to investigate neurons from various brain regions in conscious patients. This technique will be increasingly utilized due to the advent of RNS and may prove a useful approach to probe neuronal networks in other brain disorders.

Research using the Quality Outcomes Database: accomplishments and future steps toward higher-quality real-world evidence.
The Quality Outcomes Database (QOD) was established in 2012 by the NeuroPoint Alliance, a nonprofit organization supported by the American Association of Neurological Surgeons. Currently, the QOD has launched six different modules to cover a broad spectrum of neurosurgical practice-namely lumbar spine surgery, cervical spine surgery, brain tumor, stereotactic radiosurgery (SRS), functional neurosurgery for Parkinson's disease, and cerebrovascular surgery. This investigation aims to summarize research efforts and evidence yielded through QOD research endeavors. ⋯ Prospective quality registries are an important resource for observational research, yielding clinical evidence to guide decision-making across neurosurgical subspecialties. Future directions of the QOD efforts include the development of research efforts within the neuro-oncological registries and the American Spine Registry-which has now replaced the inactive spinal modules of the QOD-and the focused research on high-grade lumbar spondylolisthesis and cervical radiculopathy.

Preoperative white matter network organization and memory decline after epilepsy surgery.
Risk for memory decline is a common concern for individuals with temporal lobe epilepsy (TLE) undergoing surgery. Global and local network abnormalities are well documented in TLE. However, it is less known whether network abnormalities predict postsurgical memory decline. The authors examined the role of preoperative global and local white matter network organization and risk of postoperative memory decline in TLE. ⋯ These preliminary data suggest that global white matter network disruption contributes to verbal memory impairment preoperatively and predicts postsurgical verbal memory outcomes in left TLE. However, a leftward asymmetry of MTL white matter network organization may confer the highest risk for verbal memory decline. Although this requires replication in a larger sample, the authors demonstrate the importance of characterizing preoperative local white matter network properties within the to-be-operated hemisphere and the reserve capacity of the contralateral MTL network, which may eventually be useful in presurgical planning.

THE 2023 PRESIDENTAL ADDRESS. Celebrating advocacy: neurosurgeons as advocates.
The central focus of the 2023 annual gathering of the American Association of Neurological Surgeons in Los Angeles revolved around the concept of neurosurgeons as advocates. Beyond their roles in clinical practice and patient care, neurosurgeons frequently unite in their commitment to advocacy. This shared dedication empowers them to thrive in areas such as innovation, teaching, advanced research, and comprehensive training to shape the future of the neurosurgical field. The substantial outcome of this approach is the establishment of an environment dedicated to delivering the utmost quality of care to neurosurgery patients.

The phenotype of patients who suffer fatal traumatic brain injury (TBI) is poorly characterized. The authors examined the external causes, contributing diseases, and preinjury medication in adult patients with fatal TBI in a nationwide Finnish cohort. ⋯ TBI is a common cause of death in young adults, whereas the incidence of fatal TBI becomes increasingly higher with age in Finland. Cardiovascular diseases and psychiatric conditions were the most common diseases related to death, with opposite age trends. Healthcare facility complications were an alarmingly common cause of death in women with fatal TBI.
