Background: Recent studies suggest that the use of adjunctive intraarterial alteplase after mechanical thrombectomy (MT) may improve outcomes; however, there are limited data on the use of intraarterial tenecteplase, a newer-generation lytic, in this acute ischemic stroke patient population. Here, we evaluate the use of intraarterial tenecteplase in the ALLY pilot study (Adjunctive Intraarterial Tenecteplase Following Mechanical Thrombectomy).

Methods: ALLY was a prospective, single-center, nonrandomized pilot study assessing the feasibility and safety of intraarterial tenecteplase up to 4.

Emerging and re-emerging zoonotic diseases pose a significant threat to global health and economic security. This threat is further aggravated by amplifying drivers of change, including climate hazards and landscape alterations induced by climate change. Given the complex relationships between climate change and zoonotic disease health outcomes, a structured decision-making process is required to effectively identify pathogens of greatest concern to prioritize prevention and surveillance efforts.

Article Synopsis
  • Researchers developed a 9-point score to predict positive outcomes for patients undergoing endovascular therapy (EVT) in late-presenting strokes (6-24 hours after last known well), based on a multinational study involving over 3,200 patients.
  • The score takes into account factors like age, early CT changes, and stroke severity, with higher scores indicating a better chance of functional recovery at 90 days compared to those receiving only medical management.
  • Validation of the score showed it is a useful tool for estimating EVT outcomes, particularly benefiting patients with lower to midrange scores in terms of good functional results and independence.

Background And Purpose: We compared the outcomes of endovascular therapy (EVT) in an extended time window in patients with large-vessel occlusion (LVO) between patients with and without pre-stroke disability.

Methods: In this prespecified analysis of the multinational CT for Late Endovascular Reperfusion study (66 participating sites, 10 countries between 2014 and 2022), we analyzed data from patients with acute ischemic stroke with a pre-stroke modified Rankin Scale (mRS) score of 0-4 and LVO who underwent EVT 6-24 hours from the time last seen well. The primary outcome was the composite of functional independence (FI; mRS score 0-2) or return to the pre-stroke mRS score (return of Rankin, RoR) at 90 days.

Introduction: The benefit of endovascular therapy (EVT) among stroke patients with large ischemic core (ASPECTS 0-5) in the extended time window outside of trial settings remains unclear. We analyzed the effect of EVT among these stroke patients in real-world settings.

Patients And Methods: The CT for Late Endovascular Reperfusion (CLEAR) study recruited patients from 66 centers in 10 countries between 01/2014 and 05/2022.
