Ultra-Early Hematoma Expansion Is Associated With Ongoing Hematoma Growth and Poor Functional Outcome.

There is limited data on ultra-early hematoma growth dynamics and its clinical relevance in primary intracerebral hemorrhage (ICH). We aimed to estimate the incidence of hematoma expansion (HE) within the hyperacute period of ICH, describe hematoma dynamics over time, investigate the associations between ultra-early HE and clinical outcomes after ICH, and assess the effect of tranexamic acid on ultra-early HE. We performed a planned secondary analysis of the STOP-MSU international multicenter randomized controlled trial.

Endovascular Thrombectomy for Extracranial Internal Carotid Artery Occlusions With Large Ischemic Strokes: Insights From the SELECT2 Trial.

Background And Objectives: Although previous trials have established the efficacy and safety of endovascular thrombectomy (EVT) in large ischemic core strokes, most of them excluded patients with extracranial internal carotid artery (e-ICA) occlusion. We aimed to compare outcomes in patients with e-ICA occlusion and large ischemic core infarcts treated with EVT vs medical management (MM).

Methods: This was a secondary analysis of the SELECT2 trial, a randomized controlled trial conducted at 31 international sites.

Bridging thrombolysis with tenecteplase versus endovascular thrombectomy alone for large-vessel anterior circulation stroke: a target trial emulation analysis.

Background: Whether bridging thrombolysis with tenecteplase is beneficial compared with thrombectomy alone in patients who had a stroke with large-vessel occlusion remains unclear.

Methods: This is a causal inference study of observational data from the trials SWIFT DIRECT and EXTEND-IA TNK Parts 1 and 2 applying target trial emulation. We compared patients receiving thrombectomy alone to patients receiving tenecteplase 0.

Prourokinase vs Standard Care for Patients With Mild Ischemic Stroke: The PUMICE Randomized Clinical Trial.

Importance: Trials have not demonstrated superiority of alteplase or tenecteplase vs standard care in patients with mild stroke and have raised safety concerns. Prourokinase is an alternative fibrinolytic that may have a favorable safety profile, and the benefit-risk profile of prourokinase in mild stroke is unknown.

Objective: To investigate the efficacy and safety of prourokinase in mild ischemic stroke within 4.

An Open-Shell Fe Nitrido.

We report the photogeneration and characterization of an open-shell, terminal iron nitrido (L)Fe(N) using a sterically encumbered dipyrrin ligand environment. The Fe-N distance in the solid-state, zero-field Fe Mössbauer spectrum, and computational analysis are consistent with a triplet electronic ground state of the iron nitrido. Notably, the attenuation of Fe-N multiple bond character through occupying π* enables (i) primary C(sp)-H amination, (ii) H cleavage, (iii) aromatic C-C cleavage, and (iv) photocatalytic -atom transfer reactivity.
