Hydrogel coils in intracranial aneurysm treatment: a multicenter, prospective, randomized open-label trial.
Studies have demonstrated the effectiveness of hydrogel-coated coils (HGCs) to achieve the composite endpoint of decreased recanalization rates and greater safety. Herein, the authors aimed to assess the true ability of second-generation HGCs to prevent recanalization. ⋯ The study results did not confirm the effectiveness of second-generation HGCs using recanalization imaging data. However, these coils may induce more thrombosis and less recanalization for medium-sized cerebral aneurysms. Clinical trial registration no.: UMIN000006748 (www.umin.ac.jp/ctr/).

Skull base chordomas presenting with abducens nerve deficits: clinical characteristics and predictive factors for deficit improvement or resolution.
Skull base chordomas (SBCs) often present with cranial nerve (CN) VI deficits. Studies have not assessed the prognosis and predictive factors for CN VI recovery among patients presenting with CN VI deficits. ⋯ Overall, 68% of patients achieved at least partial recovery in CN VI function after endoscopic skull base surgery. Among patients with partial CN VI palsy at baseline, 83% achieved CN VI recovery within 6 months and 75% achieved complete recovery within 14 months. For patients who presented with a complete CN VI deficit, within those same time frames, 33% and 11% achieved partial and complete recovery, respectively. Complete preoperative CN VI deficit was associated with lower odds of CN VI recovery by 6 months. The duration of preoperative deficit does not predict functional CN VI recovery.

Prognostic value of manual versus automatic methods for assessing extents of resection and residual tumor volume in glioblastoma.
The extent of resection (EOR) and postoperative residual tumor (RT) volume are prognostic factors in glioblastoma. Calculations of EOR and RT rely on accurate tumor segmentations. Raidionics is an open-access software that enables automatic segmentation of preoperative and early postoperative glioblastoma using pretrained deep learning models. The aim of this study was to compare the prognostic value of manually versus automatically assessed volumetric measurements in glioblastoma patients. ⋯ Automatically and manually measured EOR and RT volumes have comparable prognostic properties. Automatic segmentation with Raidionics can be used in future studies in patients with glioblastoma.

Designing and clinical application of a 3D-printed personalized model of a radiofrequency needle guide with a maxillary fixator for puncture of the gasserian ganglion for trigeminal neuralgia treatment.
The purpose of this study was to present a newly designed 3D-printed personalized model (3D PPM) of a radiofrequency needle guide with a maxillary fixation for gasserian ganglion (GG) puncture. ⋯ The use of 3D PPM allows for controlled needle insertion, reducing the radiation dose to the patient and medical staff, reducing pain during a puncture needle insertion into the area of the foramen ovale, and minimizing the risk of postoperative complications.

Gender disparities in industry payments to neurosurgeons: a comprehensive analysis of Centers for Medicare & Medicaid Services Open Payments data (2016-2022).
This study aimed to investigate the extent of gender disparities in financial interactions between neurosurgeons and the medical device industry, examining the differences in the number, amount, and types of payments made to male and female neurosurgeons. ⋯ The study underscores a significant gender-based disparity in the financial interactions between neurosurgeons and the medical device industry. These disparities highlight the need for systemic changes to address the underlying factors contributing to inequity in compensation and industry collaboration opportunities. Implementing equitable compensation structures, mentorship programs, and inclusive policies is a crucial step toward achieving gender parity in neurosurgery and ensuring the field benefits from the diverse skills and perspectives of all its members.
