Background: Increased time from symptom onset to puncture (TSOP) and time from puncture to reperfusion (TPTR) are associated with worse outcome in ischemic stroke patients treated with endovascular therapy (EVT) in the early time window (<6 h). However, these associations are less described in the late window (>6 h), where patients may benefit from EVT because of a more favorable imaging profile (late window paradox). We sought to compare the effect of these timeframes between these two periods on efficacy and safety outcomes.

Comparative microanatomy and histology of spinal and cerebral veins: Implications for dural arteriovenous fistula clinical presentations.

Tissue Cell

December 2024

Laboratory of Anatomy, University of Bordeaux, Bordeaux, France; University Hospital of Bordeaux, Place Amélie Raba-Léon, Bordeaux, France; Neurosurgery Department A, Place Amélie Raba-Léon, Bordeaux, France.

Article Synopsis
  • Cranial dural arteriovenous fistulas (DAVFs) are associated with a higher risk of hemorrhage compared to spinal DAVFs, potentially due to the structural differences in veins.
  • The study examined 24 cerebral and 13 spinal veins from cadavers, finding that cerebral veins are larger in diameter but similar in wall thickness compared to spinal veins, leading to a greater diameter-to-thickness ratio.
  • This structural difference in veins may affect their pressure resistance, along with variations in pressure gradients and blood flow dynamics contributing to the differing clinical outcomes between cranial and spinal DAVFs.

  • Clozapine is effective for treatment-resistant schizophrenia but can cause significant side effects, notably excessive daytime sleepiness, which is a form of hypersomnolence.
  • A systematic review examined how clozapine affects objective measures of hypersomnolence, analyzing six studies using various testing methods like polysomnography (PSG).
  • Initial findings showed clozapine led to longer sleep times and quicker sleep onset, but these effects did not last beyond 4-6 weeks, indicating a need for further long-term research on sleep patterns and wakefulness in clozapine-treated patients.
