Intravenous thrombolysis in young adults with ischemic stroke: A cohort study from the international TRISP collaboration.

Background And Aims: Previous observational data indicate that young adults treated with intravenous thrombolysis (IVT) for acute ischemic stroke have more favorable outcomes and less complications when compared to older adults. Given the limited data on this topic, we aimed to provide more evidence on clinical outcomes and safety in such patients, using a large international thrombolysis registry.

Methods: In this prospective multicenter study, we used data from the Thrombolysis in Ischemic Stroke Patients (TRISP) registry from 1998 to 2020.

Comparison of functional and safety outcomes between the extended versus early time window after intravenous thrombolysis and endovascular thrombectomy.

Introduction: Based on recent trials regarding the early time window, omitting intravenous thrombolysis (IVT) before endovascular thrombectomy (EVT) in eligible patients seems unjustified. Whether this also concerns the extended time window, 4.5 to 9 h from last seen well, is yet unclear.

Unregulated smooth-muscle myosin in human intestinal neoplasia.

A recent study described a recessive ATPase activating germ-line mutation in smooth-muscle myosin (smmhc/myh11) underlying the zebrafish meltdown (mlt) phenotype. The mlt zebrafish develops intestinal abnormalities reminiscent of human Peutz-Jeghers syndrome (PJS) and juvenile polyposis (JP). To examine the role of MYH11 in human intestinal neoplasia, we searched for MYH11 mutations in patients with colorectal cancer (CRC), PJS and JP.
