Adaptive Multistep Prediction With Sequence-to-Sequence (Seq2Seq) Models.

This brief demonstrates for the first time that the sequence-to-sequence (Seq2Seq) model is an adaptive multistep predictor. The Seq2Seq model is fixed-weight adaptive, which means that the model can adapt to time-varying behaviors without having to update its weights and biases. Instead, the learning algorithm is embedded into the recurrent neural network (RNN) decoder.

Effectiveness and Safety in Patients with Non-Valvular Atrial Fibrillation Who Switched from Warfarin to Direct Oral Anticoagulants in Medicare Population.

Introduction: Atrial fibrillation (AF), a common heart rhythm abnormality, is linked to a higher risk of stroke. Traditionally, warfarin has been the primary anticoagulation treatment for reducing the stroke risk. The new standard of treatment by direct oral anticoagulants (DOACs) offers greater benefits including improved efficacy and fewer adverse effects with reduced monitoring.

Disassembly of Virus-Like Particles and the Stabilizing Role of the Nucleic Acid Cargo.

In many simple viruses and virus-like particles, the protein capsid self-assembles around a nucleic-acid genome. Although the assembly process has been studied in detail, relatively little is known about how the capsid disassembles, a potentially important step for infection (in viruses) or cargo delivery (in virus-like particles). We investigate capsid disassembly using a coarse-grained molecular dynamics model of a = 1 dodecahedral capsid and an RNA-like polymer.

Longer disease progression milestone-free time in people with amyotrophic lateral sclerosis treated versus not treated with intravenous edaravone: results from an administrative claims analysis.

To estimate time-to-progression milestones in people with amyotrophic lateral sclerosis (PALS) treated versus not treated with intravenous (IV) edaravone (Radicava IV, Mitsubishi Tanabe Pharma America [MTPA], hereafter "IV edaravone") in a real-world setting. IV edaravone is US FDA approved for the treatment of ALS and was shown in clinical trials to slow the rate of physical functional decline. This retrospective observational analysis included PALS continuously enrolled in Optum's Clinformatics Data Mart between 8 August 2017 and 31 December 2021.

Brain Age Modeling and Cognitive Outcomes in Young Adults With and Without Sickle Cell Anemia.

Importance: Both sickle cell anemia (SCA) and socioeconomic status have been associated with altered brain structure and cognitive disability, yet precise mechanisms underlying these associations are unclear.

Objective: To determine whether brains of individuals with and without SCA appear older than chronological age and if brain age modeling using brain age gap (BAG) can estimate cognitive outcomes and mediate the association of socioeconomic status and disease with these outcomes.

Design, Setting, And Participants: In this cross-sectional study of 230 adults with and without SCA, individuals underwent brain magnetic resonance imaging (MRI) and cognitive assessment.
