001), and treatments for metastasis (P < 0.001) or glioma (P < 0.001) were associated with symptomatic complaints leading to imaging, but no factors were associated with higher rates of abnormal imaging.

Gamma Knife therapy remains a safe treatment for multiple indications, but it is not risk free and acute symptomatic complaints are common. However, our data suggest that the need for reimaging within 30 days for symptomatic complaints is likely overestimated as obtained imaging does not usually show any change and the rate of significant complication is exceedingly low.

Some patients with glioblastoma multiforme (GBM) survive 3-5 years (or longer) after diagnosis. The goal of this study was to identify differences between the long-term survivors (LTS) and those who had a shorter overall survival (non-LTS groups).

This study was a retrospective analysis of prospectively maintained surgical databases. All patients who underwent safe maximal resection for GBM were included. Demographic, clinical, radiologic, and pathologic data were obtained from electronic medical records. Values of the biomarkers of systemic inflammation were computed from the preoperative hemogram reports. Patients with an overall survival (OS) ≥36 months were defined as the LTS group and were compared with the non-LTS groups (OS<36 months).

Patients in the LTS group were younger, had a better baseline performance status, and were more likely to have undergone near- or gross-total resection. LTS was associated with lower Ki67 labeling, MGMT methylation, IDH mutation, and lack of p53 overexpression. Several novel findings were generated by this study. A longer pretreatment duration of symptoms was associated with a longer OS. Higher pretreatment levels of the absolute neutrophil count, neutrophil-lymphocyte ratio, monocyte-lymphocyte ratio, derived neutrophil-lymphocyte ratio and systemic index of inflammation, and lower levels of the absolute eosinophil count and eosinophil-lymphocyte ratio all correlated with a shorter OS.

Several differences were identified between the LTS and non-LTS groups. These differences will likely be incorporated into future prognostic models. They may also aid in differentiation between recurrent disease and treatment-related changes.

Traditional craniotomy relies on the surgeon's experience and can be complicated owing to excessive skull bone removal, undesirable brain tissue penetration, or severe bleeding. For craniotomy, we developed a robot system based on intraoperative cone-beam computed tomography image guidance and human-robot cooperative interaction, aiming to improve the safety and accuracy of surgery and reduce the labor-intensiveness of the procedure.

Intraoperative cone-beam computed tomography image guidance was adopt to improve the accuracy in our experiment. Craniotomy was performed using an interactive method based on human-robot collaboration, which could achieve a natural interactive method in accordance with surgeons' operating habits. The frequency-based method of contact distinction and the method of torque estimation were used to improve the safety of the designed robot.

An animal experiment was conducted to verify the effectiveness of the robot system. During the drilling process, the position error was 0.92 ± 0.17 mm (upper surface) and 0.97 ± 0.11 mm (lower surface), and the angle error was 3.37 ± 1.43°. During the milling process, the position error was 1.06 ± 0.13 mm (upper surface) and 1.09 ± 0.09 mm (lower surface). The results showed that the system had sufficient precision and could better complete craniotomy with human-robot collaboration. In addition, with the feedback of multisensor information, the robot system could achieve a sufficient level of safety.

The robot system can achieve accurate positioning and safe user-friendly human-robot interaction, which solves problems encountered in the drilling and milling of craniotomy, meets clinical needs, and provides a new method for robot-assisted craniotomy.

Practice consolidation in healthcare has widespread consequences for providers and patients. Although many studies describe this phenomenon in various medical specialties, no such analysis has been performed in neurosurgery specifically. The goal of this study was to assess the trends in the size of U.S. neurosurgery practices over a 5-year period.

Neurosurgery practice characteristics were obtained from the Medicare Physician Compare database from March 2014 through October 2019 on the Centers for Medicare & Medicaid Services Website. Neurosurgeons were separated on the basis of their practice size. click here Group practice sizes ranged from solo practitioner practice to large multispecialty groups and health organizations. Eight groups were identified (1 or 2, 3-9, 10-24, 25-49, 50-99, 100-499, 500-999, and ≥1000 members). Additionally, neurosurgery practices were analyzed across the 4 U.S. geographical regions to understand changes in practice size and distribution.

The percentage of neurosurgeons in smaller practices of 1 or 2 members decreased, from 20.09% to 13.05%; 3-9 members, from 17.79% to 9.41%; and 10-24 members, from 10.53% to 8.0%. The largest increase was seen in health organizations of 1000 members or more, with an increase from 9.85% to 22.84%.

This study shows that over the past 5 years, a substantial trend toward increasing practice sizes has evolved. The effect of the differences in practice size should be examined to determine the large-scale impacts on patient care, payment models, and healthcare access,in addition to neurosurgeon compensation, and satisfaction.
