Endovascular embolization of brain arteriovenous malformations (AVMs) is sometimes intentionally partial, in the case of staged treatment for instance. Residual AVMs may be prone to angioarchitectural modification during follow-up. The objective of this work is to evaluate the nature and extent of these modifications. ⋯ Angioarchitectural modifications (both progression and regression) of brain AVMs are frequent findings after partial embolization. Nidal volume growth is associated with longer time intervals between embolization and follow-up.

Bundled payment for care improvement advanced (BPCIA) is a voluntary alternative payment model administered by the Centers for Medicare and Medicaid Services using value-based care to reduce costs by incentivizing care coordination and improved quality. We aimed to identify drivers of negative financial performance in BPCIA among patients undergoing spinal fusion surgery. ⋯ Nonelective spinal surgery is an independent preoperative predictor of negative financial performance in BPCIA. Nonelective spinal surgeries are more likely than elective surgeries to have higher length of stay, nonhome discharge, 90-day hospital readmission, 90-day additional nonspine surgeries, and less time spent at home during the bundled period, all of which contribute to higher health care utilization. The Centers for Medicare and Medicaid Services should consider incorporating nonelective spine surgery into risk-adjustment models.

Despite the globalization of health information, collaborations between high-income countries (HICs) and low/middle-income countries (LMICs), while present, could still increase. This study builds on previous research highlighting LMIC underrepresentation in neurosurgery literature. We conducted a comprehensive bibliometric analysis using the Scopus database to investigate collaborative neurosurgical research between HIC institutions and those in low-income country (LIC)/LMICs. ⋯ Global guidelines and consensus papers can enhance patient care, but LMICs' involvement remains limited. Further attention to training and collaboration initiatives is needed. This study emphasizes the importance of promoting collaboration and training between countries with varying resources to advance neurosurgical care globally.
