The impact of general anesthesia versus non-general anesthesia on thrombectomy outcomes by occlusion location: insights from the ETIS registry.
Identifying the optimal anesthetic technique for mechanical thrombectomy (MT) remains an unresolved issue. Prior research has not considered the influence of occlusion site when comparing general anesthesia (GA) with non-GA. This study evaluates the differential impacts of the anesthetic technique (GA vs non-GA) on outcomes according to the location of occlusion. ⋯ While GA and non-GA techniques did not differ significantly in functional outcomes, the influence of GA on angiographic and procedural safety outcomes was location dependent, underscoring the importance of a tailored anesthesia technique in MT procedures.

ReviewGenetics and molecular pathophysiology of normal pressure hydrocephalus.
Idiopathic normal pressure hydrocephalus (iNPH) is characterized by dilation of the cerebral ventricles without increased cerebral pressure. Patients typically present with cognitive impairment, gait abnormalities, and urinary incontinence. ⋯ Familial cases and genomic studies of iNPH have recently suggested an underappreciated role of genetics in disease pathogenesis, implicating mechanisms ranging from dysregulated CSF dynamics to underlying neurodegenerative or neuroinflammatory processes. In this paper, the authors provide a brief review of genetic insights and candidate genes for iNPH, highlighting the continued importance of integrated genetic analysis and clinical studies to advance iNPH management.

Impact of proton versus photon adjuvant radiotherapy on overall survival in the management of skull base and spinal chordomas: a National Cancer Database analysis.
Chordomas are rare tumors that originate from undifferentiated remnants of the notochord. Currently, there are no established guidelines regarding the choice of adjuvant radiation modality for patients surgically treated for chordomas. Using a nationwide, multicenter database, the authors aimed to compare long-term survival outcomes associated with the use of proton or photon adjuvant therapy for the management of chordomas of skull base and spine. ⋯ Based on this nationwide analysis, patients with private insurance and higher income were more likely to receive proton adjuvant radiotherapy, while those with spinal or sacral chordomas were less likely to receive this modality. Despite this disparity, an OS benefit was observed in patients with chordomas of the spine and sacrum who received adjuvant proton therapy, in comparison with a matched cohort of patients treated with photon therapy. Conversely, this advantageous outcome was not evident in cases of chordomas located at the skull base.

Efficacy of subcutaneous sumatriptan in postcraniotomy pain and opioid consumption.
Traditional pain management pathways following craniotomy are predicated on opioids. However, narcotics can confound critical neurological examination, contribute to respiratory depression, lower the seizure threshold, and lead to medication habituation, dependence, and/or abuse. Alternative medications to better address postoperative pain while mitigating opioid-related adverse effects remain insufficiently studied. Preliminary studies suggest sumatriptan, a 5-HT (1B/1D) receptor agonist known to regulate dural vasoactivity and inflammation, may moderate pain following trigeminal microvascular decompression and chronic postcraniotomy headache. In this study, the authors evaluated the efficacy of sumatriptan to modulate pain and opioid requirements following craniotomy surgery. ⋯ Postoperative single-dose subcutaneous sumatriptan following elective craniotomy may reduce pain scores and opioid requirements. Additional studies are needed to better understand nuanced differences in opioid modulation and optimal patient selection.
