Flow capacity of a superficial temporal artery as a donor in a consecutive series of 100 patients with superficial temporal artery-middle cerebral artery bypass.
A superficial temporal artery-middle cerebral artery (STA-MCA) bypass is classically considered a low-flow bypass. It is known that the flow in the flow augmentation STA-MCA bypass is influenced by flow demand of the revascularized territory and can reach significantly higher values. The authors report their intraoperative flow measurement data in a consecutive series of 100 STA-MCA bypasses performed at their institution. Moreover, in a subanalysis, they show the postoperative bypass flow measured with quantitative MR angiography (qMRA) noninvasive optimal vessel analysis (NOVA). ⋯ Using intraoperative and postoperative quantitative flow measurements of the STA, the data confirm that the flow in the flow augmentation STA-MCA bypass is influenced by the flow demand of the revascularized territory and can reach high values if needed. Moreover, the significant flow increase in the postoperative flow measurement using qMRA-NOVA demonstrates that the bypass can increase its flow over time.

The power of social media: broader Twitter outreach and higher Altmetric scores significantly amplify neurosurgical citation reach.
The authors sought to quantify the role of social media-related academic activity through use of the Altmetric score (a composite score based on social media attention from a variety of sources) and investigate its potential impact on the number of citations received at 3 years postpublication (articles published between January 2019 and December 2019). ⋯ The authors report a strong, statistically significant correlation between the Altmetric score and the number of citations received. To their knowledge, this is the first study to demonstrate the impact of social media academic activity on neurosurgery article citation dissemination, potentially influencing resident medical education.

The authors sought to determine the medical schools with the highest number and proportion of female graduates currently practicing neurosurgery and to identify medical school characteristics that increase female representation in neurosurgery, with the goal of addressing the gender disparity. ⋯ Achieving gender diversity in neurosurgery necessitates a multifaceted approach. Institutions with a higher number and proportion of female neurosurgery graduates emphasized female-female mentorship, fostered diversity initiatives, and implemented inclusive policies. To increase female representation in neurosurgery, it is crucial to establish robust mentorship programs that provide aspiring female neurosurgeons with the guidance, support, and motivation required to navigate a traditionally male-dominated field.

Multicenter Study Comparative StudyDecompressive craniectomy in symptomatic intracerebral hemorrhage after ischemic stroke: a multicenter retrospective cohort study.
Symptomatic intracerebral hemorrhage (sICH) after stroke is a devastating neurological complication. Current guidelines support a "possible benefit" of decompressive craniectomy (DC) for large supratentorial sICH with significant mass effect. ⋯ DC after sICH did not improve functional outcome at 90 days according to multivariable analysis, although younger age and absence of previous cancer history were associated with improved outcomes.

Comparative StudyMetabolic profiling of atypical meningioma and recurrent meningioma: a comparative analysis with proton magnetic resonance spectroscopy.
Meningiomas are predominantly benign, but some cases exhibit recurrent growth after surgery and undergo malignant transformation to WHO grade 2 or grade 3. Despite progress in genetic analyses, advancements in metabolomic analysis remain less established. Herein, the authors investigated metabolic activity differences between WHO grade 1 meningiomas and WHO grade 2 or 3 meningiomas by noninvasively using proton magnetic resonance spectroscopy (1H-MRS), aiming to preoperatively estimate malignancy. They also reviewed the literature to elucidate this aspect of meningioma research. ⋯ In cases pathologically graded as WHO grade 2 or 3 meningiomas, metabolic products such as glutamine, glutamate, lipids, and choline increased significantly. These changes were correlated with elevation of the MIB-1 LI. In group II, the mean MIB-1 LI was 8.58, significantly higher than in group I, suggesting a strong association with pathological malignancy. Therefore, 1H-MRS may help to noninvasively predict tumor metabolic activity and tumor recurrence. Furthermore, the authors concluded from the ROC analysis that glutamine may be a potential indicator of future growth of meningioma and benefits of early surgery.
