LI-RADS US Surveillance Version 2024 for Surveillance of Hepatocellular Carcinoma: An Update to the American College of Radiology US LI-RADS.

In 2017, the American College of Radiology introduced the US Liver Imaging Reporting and Data System (LI-RADS) as a framework for US surveillance of patients at risk for developing hepatocellular carcinoma. This has aided in the standardization of technique, clinical reporting, patient management, data collection, and research. Emerging evidence has helped inform changes to the algorithm, now released as LI-RADS US Surveillance version 2024.

Left Atrial Appendage Closure in Atrial Fibrillation Patients with Cancer.

: There are limited data about left atrial appendage closure (LAAC) in patients with cancer. We therefore sought to compare the outcome after LAAC in patients with vs. without cancer in a multicentre registry.

N-glycan core tri-fucosylation requires Golgi α-mannosidase III activity that impacts nematode growth and behavior.

N-glycans with complex core chitobiose modifications are observed in various free-living and parasitic nematodes but are absent in mammals. Using Caenorhabditis elegans as a model, we demonstrated that the core N-acetylglucosamine (GlcNAc) residues are modified by three fucosyltransferases (FUTs), namely FUT-1, FUT-6, and FUT-8. Interestingly, FUT-6 can only fucosylate N-glycans lacking the α1,6-mannose upper arm, indicating that a specific α-mannosidase is required to generate substrates for subsequent FUT-6 activity.

Stroke recurrence after transcatheter PFO closure in patients with cryptogenic stroke.

Background: Patent foramen ovale (PFO) closure is recommended for secondary prevention of cryptogenic stroke. However, data on long-term results are limited. We aimed to evaluate safety and efficacy of transcatheter PFO closure and predict neurologic recurrence.
