Impact of Neurosurgery Research and Education Foundation awards on subsequent grant funding and career outcomes of neurosurgeon-scientists.
The Neurosurgery Research and Education Foundation (NREF) provides diverse funding opportunities for in-training and early-career neurosurgeon-scientists. The authors analyzed the impact of NREF funding on the subsequent career success of neurosurgeons in obtaining research funding and academic achievements. ⋯ In-training and early-career neurosurgeons who were awarded NREF funding had significant success in acquiring subsequent grant support, research productivity, and achievements of academic rank. NREF grants provide a tremendous return on investment across various career stages and subspecialities. They also appeared to have a broader impact on trajectory of research and innovation within the field of neurosurgery.

Focused ultrasound-mediated blood-brain barrier opening in Alzheimer's disease: long-term safety, imaging, and cognitive outcomes.
MRI-guided low-intensity focused ultrasound (FUS) has been shown to reversibly open the blood-brain barrier (BBB), with the potential to deliver therapeutic agents noninvasively to target brain regions in patients with Alzheimer's disease (AD) and other neurodegenerative conditions. Previously, the authors reported the short-term safety and feasibility of FUS BBB opening of the hippocampus and entorhinal cortex (EC) in patients with AD. Given the need to treat larger brain regions beyond the hippocampus and EC, brain volumes and locations treated with FUS have now expanded. To evaluate any potential adverse consequences of BBB opening on disease progression, the authors report safety, imaging, and clinical outcomes among participants with mild AD at 6-12 months after FUS treatment targeted to the hippocampus, frontal lobe, and parietal lobe. ⋯ This study is the largest cohort of participants with mild AD who received FUS treatment, and has the longest follow-up to date. Safety was demonstrated in conjunction with reversible and repeated BBB opening in multiple cortical and deep brain locations, with a concomitant reduction of β-amyloid. There was no apparent cognitive worsening beyond expectations up to 1 year after FUS treatment, suggesting that the BBB opening treatment in multiple brain regions did not adversely influence AD progression. Further studies are needed to determine the clinical significance of these findings. FUS offers a unique opportunity to decrease amyloid plaque burden as well as the potential to deliver targeted therapeutics to multiple brain regions in patients with neurodegenerative disorders.

Neuro-oncology authorship trends in gender since 1944: a systematic review of 14,020 articles from five top-tier academic journals.
This study was performed to compare authorship trends, by gender, in the neurosurgical oncology literature. ⋯ Female authorship in top neuro-oncology journals has increased since the 1940s, with female-led teams showing greater gender diversity. However, female researchers lag behind their male counterparts in quantity of published research and are less likely to hold first or last authorship positions. This difference is more pronounced in the three neurosurgical oncology journals than in the two medical neuro-oncology journals, which may reflect the relatively low female representation in neurosurgery relative to medical oncology. Collectively, these trends have meaningful implications for career advancement, which is often dependent on academic productivity.

Cost-effectiveness of invasive monitoring strategies in epilepsy surgery.
Drug-resistant epilepsy occurs in up to 40% of patients with epilepsy who may be considered for epilepsy surgery. For drug-resistant focal epilepsy, up to 50% of patients require invasive monitoring prior to surgery. Of the most common invasive monitoring strategies (subdural electrodes [SDEs] and stereo-electroencephalography [sEEG]), the most cost-effective strategy is unknown despite substantial differences in morbidity profiles. ⋯ In this analysis, based on available observational data and estimates of complication costs, invasive monitoring with either SDEs or sEEG was nearly equivalent in terms of cost-effectiveness.
