Temporal trends of prescription rates, oral anticoagulants dose, clinical outcomes and factors associated with non-anticoagulation in patients with incident atrial fibrillation.

Objective: To analyze the temporal trends of oral anticoagulant (OAC) prescription, direct oral anticoagulant (DOAC) dose, clinical outcomes and factors associated with non-anticoagulation in patients with incident atrial fibrillation (AF).

Patients And Methods: During January 1, 2011, to December 31, 2020, a total of 249,107 patients with newly diagnosed AF were identified, and the 1-year risks of ischemic stroke, intracranial hemorrhage (ICH), and all-cause mortality were analyzed.

Results: OAC prescription increased from 22.

Correlation between the structures of natural polysaccharides and their properties in regulating gut microbiota: Current understanding and beyond.

Natural polysaccharides have complex structural properties and a wide range of health-promoting effects. Accumulating evidence suggests that the effects are significantly mediated through fermentation by gut microbiota. In recent years, the relationship between the structures of natural polysaccharides and their properties in regulating gut microbiota has garnered significant research attention as researchers attempt to precisely understand the role of gut microbiota in the bioactivities of natural polysaccharides.

Hybrid strains of enterotoxigenic/Shiga toxin-producing , United Kingdom, 2014-2023.

Diarrhoeagenic (DEC) pathotypes are defined by genes located on mobile genetic elements, and more than one definitive pathogenicity gene may be present in the same strain. In August 2022, UK Health Security Agency (UKHSA) surveillance systems detected an outbreak of hybrid Shiga toxin-producing /enterotoxigenic (STEC-ETEC) serotype O101:H33 harbouring both Shiga toxin () and heat-stable toxin (). These hybrid strains of DEC are a public health concern, as they are often associated with enhanced pathogenicity.

Characterisation of the ocular inflammatory response to AAV reveals divergence by sex and age.

Progress for ocular AAV gene therapy has been hindered by AAV-induced inflammation, limiting dose escalation and long-term efficacy. Broadly, the extent of inflammatory responses alters with age and sex, yet these factors are poorly represented in pre-clinical development of ocular AAV gene therapies. Here, we combined clinical imaging, flow cytometry and bulk-sequencing of sorted microglia to interrogate the longitudinal inflammatory response following intravitreal delivery of AAV2 in young (3-month), middle aged (9-month) and old (18-month) Cx3cr1-creER:R26tdTomato+/- mice of both sexes.

YOLOSeg with applications to wafer die particle defect segmentation.

This study develops the you only look once segmentation (YOLOSeg), an end-to-end instance segmentation model, with applications to segment small particle defects embedded on a wafer die. YOLOSeg uses YOLOv5s as the basis and extends a UNet-like structure to form the segmentation head. YOLOSeg can predict not only bounding boxes of particle defects but also the corresponding bounding polygons.
