We sought to assess the accuracy of a novel parameter proportional to the rod shear stress (RSS) in identifying patients at risk of rod fracture (RF) after surgery for correction of adult spinal deformity. ⋯ The RSS is calculated using easily obtainable information and shows potential as a tool for predicting patient-specific risk of RF after spinal fusion. The number of instrumented levels also correlates strongly with the occurrence of RFs and is not significantly less accurate than the RSS. A larger sample size and prospective validation would be useful in determining with greater confidence which parameter is superior for predicting RFs after spinal fusion.

Acute glaucoma is a potential complication of carotid revascularization procedures such as endarterectomy or stenting. Although preoperative ocular hypoperfusion may predispose patients to postoperative glaucoma, the details of this complication have not been clarified. ⋯ This study was the first to clarify the risk factors and characteristics of acute glaucoma after carotid revascularization.

Systematic Review and Case of Thrombectomy for Pediatric Stroke Due to Myxoma Embolism.
Stroke presentation secondary to a cardiac myxoma thromboembolism is rare in the pediatric population. Because of such rarity, the reported cases in the literature are primarily case reports. Additionally, general pediatric stroke management lacks evidence-based guidelines because of its low incidence and lack of clinical trials. In pediatric strokes identified from a cardiac myxoma, the incidence favors boys with the classical presentation of unilateral weakness and aphasia. We present a pediatric patient who presented with strokelike symptoms secondary to an intracranial embolus from a previously undiagnosed cardiac myxoma. ⋯ We describe an urgent mechanical thrombectomy and share preoperative and postoperative images and pathology slides confirming a stroke from myxoma origin. We provide added insight in the safe use of mechanical thrombectomy as treatment for pediatric strokes secondary to a thromboembolism.

Numerous studies suggest that the gut microbiota closely linked to cerebrovascular diseases, such as Intracranial aneurysm (IA) and aneurysmal subarachnoid hemorrhage (aSAH). Nevertheless, the confirmation of a definitive causal connection between gut microbiota, IA, and aSAH is still pending. The aim of our research is to explore the potential bidirectional causality among them. ⋯ This MR analysis investigated the causal associations between gut microbiota, IA, and aSAH risks. The findings expanded current knowledge of the microbiota-gut-brain axis and offered novel perspectives on preventing and managing these conditions.

The high incidence of nonunion in osteoporosis vertebral compression fractures (OVCFs) among the elderly population is a significant concern. But the hypothesis about etiopathogenesis of the intravertebral cleft (IVC) is not convincing. This study aims to investigate the association between spinopelvic parameters and IVC. ⋯ According to the results of this study, large DSVA was a risk factor for IVC formation in patients with OVCFs. Patients with global spinal malalignment should be actively observed during conservative treatment.
