Prior anticoagulation and bridging thrombolysis improve outcomes in patients with atrial fibrillation undergoing endovascular thrombectomy for anterior circulation stroke.

Background: Where stroke occurs with pre-existing atrial fibrillation (AF)studies validating the safety and efficacy of bridging thrombolysis, and the use of endovascular thrombectomy (EVT) in the setting of prior anticoagulation, are limited to single-center reports.

Methods: In a retrospective analysis, AF patients undergoing EVT for anterior circulation large vessel occlusion stroke enrolled in a prospectively-maintained, international multicenter database (International Stroke Perfusion Imaging Registry (INSPIRE)) between 2016 and 2019 were studied. Patients were categorized by anticoagulation status: anticoagulated (warfarin/non-vitamin K oral anticoagulants) versus not anticoagulated.

Processing renewable and waste-based feedstocks with fluid catalytic cracking: Impact on catalytic performance and considerations for improved catalyst design.

Refiners around the globe are either considering or are actively replacing a portion of their crude oil inputs originating from fossil sources with alternative sources, including recycled materials (plastics, urban waste, mixed solid waste) and renewable materials (bio-mass waste, vegetable oils). In this paper, we explore such replacement, specifically focusing on the fluid catalytic cracking (FCC) operation. Five pyrolysis oils, obtained from municipal solid waste (MSW) and biogenic material (olive stones/pits), were fully characterized and tested at 10% loading against a standard fluid catalytic cracking (FCC) vacuum gasoil (VGO) feed in a bench scale reactor using an industrially available fluid catalytic cracking catalyst based on ultrastable Y zeolite to simulate fluid catalytic cracking co-processing.
