To study associations of clinical characteristics and treatment choice with functional outcome, mortality, and time to death in a national sample of aneurysmal subarachnoidal hemorrhage patients. ⋯ The patient selection in Sweden after aneurysmal subarachnoidal hemorrhage showed similar values for dGOSE, 1-year mortality, and survival probability between patients treated with microsurgery or endovascular technique. Poor dWFNS, higher age, and DIND were significantly associated with unfavorable dGOSE, mortality, and survival probability. Pupil dilatation was significantly associated with mortality and survival probability.

Comparative Study
Collagen Membrane as artificial Dura Substitute: A Comprehensive in vivo study of efficiency and substitution compared to Durepair.
The dura mater is a barrier between the brain and the surrounding environment. Injuries to the dura can lead to serious complications, therefore, ensuring a hermetic closure of the dura is a primary task for a neurosurgeon. The aim of the study is to compare the effectiveness of applying the newly developed ViscollDURA collagen membrane (VDCM), with the commercially available Durepair (xenogeneic collagen) in animal model. ⋯ Both membranes showed safety and compatibility. The collagen membrane produced under sterile conditions demonstrated better regeneration with minimal inflammatory reaction. The study suggests that VDCM exhibits biocompatibility comparable to Durepair, providing prospects for potential applications in neurosurgery.

The subspecialized, clinically complex nature of neurosurgery should not result in marginalization or under-representation of neurosurgical scientific output. This study aims to provide an overview of the trends of neurosurgical publications in high-impact medical journals during the past 3 decades. ⋯ Neurosurgery's proportion of high-impact journal publications has increased over time.

Brain metastases (BMs) are the most frequent tumors of the central nervous system. Diffusion tensor imaging (DTI) is a magnetic resonance imaging technique that provides insights into brain microstructural alterations and tensor metrics and generates tractography to visualize white matter fiber tracts based on diffusion directionality. This systematic review assessed evidence from DTI biomarker alterations in BMs and comparable tumors such as glioblastoma. ⋯ DTI metrics provide noninvasive biomarkers for distinguishing BMs from other tumors and predicting outcomes. Key metrics included peritumoral FA and mean diffusivity.

Within neurosurgery, it has always been important to individualize patient care. In recent years, however, technological advances have brought a new dimension to personalized care as developing methods, including next-generation sequencing, have enabled us to molecularly profile pathologies with increasing scale and resolution. In this review, the authors discuss the history and advances in precision medicine and neurosurgery, focusing both on neuro-oncology, as well as its extension to other neurosurgical subspecialties. They highlight the important roles of neurosurgeons in past work and future work, with the extension of tissue collection and precision medicine principles to additional sample types and disease indications.
