Background: The duration of mechanical thrombectomy (MT) is a negative predictor of outcomes in acute ischemic stroke (AIS), yet the precise mechanisms are unclear. We investigated whether the placement of large-bore catheters intracranially reduces blood flow to the ischemic penumbra and diminishes the efficacy of MT.

Methods: We investigated the impact of different catheter sizes on flow through the intracranial circulation using an in vitro model.

Background: An estimated 185,000 patients per year undergo an extremity amputation in the United States (over 500 amputations/day). Prolonged postoperative opioid use, defined as the presence of a filled opioid prescription between 90 and 180 days following the operative amputation procedure, affects nearly 50% of amputees. Moreover, the use of preoperative benzodiazepines, muscle relaxants, anticonvulsants, and antidepressants is strongly linked to prolonged opioid use suggesting new therapeutic strategies are needed.

Article Synopsis
  • The study explores the impact of revision surgery on patient-reported outcomes (PROs) following initial surgeries for grade 1 spondylolisthesis, comparing decompression-only and decompression plus fusion (D+F) treatments.
  • Data was collected from over 600 patients, revealing that 13.3% of decompression-only patients and 9.8% of D+F patients required revision surgery within 5 years, with revision patients reporting worse outcomes.
  • The findings indicate that while revision surgery affects PROs adversely, patients undergoing D+F see a more significant decline in their reported outcomes compared to those who only had decompression surgery.

Article Synopsis
  • This study is a retrospective analysis of data collected from patients who underwent surgery for low grade spondylolisthesis, aiming to identify factors that predict delayed improvement post-surgery.
  • Among the 436 patients included, most experienced quick clinical enhancements, but about 21.4% showed delayed recovery, reaching the minimal clinically important difference (MCID) at 12 months rather than 3 months.
  • Key factors linked to this delayed improvement were poorer pre-surgery walking ability, better initial pain scores, and worse leg pain scores at the 3-month mark.*
