Racial and socioeconomic disparities in spine surgery for degenerative lumbar spondylolisthesis persist in the United States, potentially contributing to unequal health-related quality of life (HRQoL) outcomes. This is important as lumbar spondylolisthesis is one of the most common causes of surgical low back pain, and low back pain is the largest disabler of individuals worldwide. Our objective was to assess the relationship between race, socioeconomic factors, treatment utilization, and outcomes in patients with lumbar spondylolisthesis. ⋯ This study found that BIPOC patients were less likely to use spine surgery for degenerative lumbar spondylolisthesis despite reporting higher pain interference, suggesting an association between race and surgical utilization. These disparities may contribute to unequal HRQoL outcomes for patients with lumbar spondylolisthesis and warrant further investigation to address and reduce treatment disparities.

The incidence of imminent new vertebral fracture (NVF) is notably high after vertebral augmentation (VA), but accurately assessing the imminent risk of NVF remains a great challenge. The aim of this study was to investigate whether the MRI-based vertebral bone quality (VBQ) score can predict the risk of imminent NVF after VA within a 2-year period. ⋯ The VBQ score obtained from lumbar MRI can be used to assess the VBQ and predict the imminent NVF after VA in patients with osteoporotic vertebral compression fracture.

Craniocervical junction (CCJ) arteriovenous fistulas (AVFs) are rare. Variability in clinical manifestations and treatment strategies for CCJ AVFs stems from differences in their angioarchitecture. Our study aims to categorize CCJ AVFs based on their angioarchitecture and explore the associated clinical features and treatment modalities for distinct CCJ AVF types. ⋯ CCJ AVFs can be distinguished based on the fistula location and the arterial feeders. Currently, microsurgery stands as the preferred treatment strategy for CCJ AVFs, whereas interventional embolization plays a distinctive role in cases with specific angioarchitecture or as a pretreatment measure before microsurgery.

This study identified a clinically significant subset of patients with glioma with tumor outside of contrast enhancement present at autopsy and subsequently developed a method for detecting nonenhancing tumor using radio-pathomic mapping. We tested the hypothesis that autopsy-based radio-pathomic tumor probability maps would be able to noninvasively identify areas of infiltrative tumor beyond traditional imaging signatures. ⋯ This study developed a multistage model for mapping gliomas using autopsy tissue samples as ground truth, which was able to identify regions of tumor beyond traditional imaging signatures.

Hypoglycemia is a known risk of intensive postoperative glucose control in neurosurgical patients. However, the impact of postoperative hypoglycemia after craniotomy remains unexplored. This study aimed to determine the association between postoperative hypoglycemia and mortality in patients undergoing elective craniotomy. ⋯ Among patients undergoing an elective craniotomy, moderate hypoglycemia and severe hypoglycemia are associated with increased mortality, major morbidity, and prolonged hospital stays. In addition, the risk of mortality and major morbidity increases with the number of hypoglycemia episodes.
