AI Article Synopsis
- The study focuses on a modified script training intervention called Video-Implemented Script Training for Aphasia (VISTA) aimed at improving speech in people with Primary Progressive Aphasia (PPA), a disorder that affects language skills.
- Thirteen bilingual participants (Spanish-Catalan) with different variants of PPA underwent the training over 8 weeks, with evaluations on their script accuracy and production quality at multiple time points.
- Results indicated significant improvements in various speech measures regardless of whether the training was conducted via teletherapy or in-person, highlighting the effectiveness and acceptability of the intervention for individuals with different PPA variants.
Article Abstract
Purpose: Primary progressive aphasia (PPA) is a neurodegenerative disorder characterized by worsening of speech and/or language. Script training intervention promotes automatized speech production via repeated practice of scripted content. This study evaluated the acceptability, feasibility, and effects of a modified version of Video-Implemented Script Training for Aphasia (VISTA) in the three PPA variants and compared outcomes by intervention modality (teletherapy vs. in person).
Method: Thirteen bilingual (Spanish-Catalan) participants were included (semantic variant, = 5; logopenic variant, = 5; nonfluent/agrammatic variant, = 3; teletherapy, = 7). Using a nonrandomized design, intervention was administered in participants' dominant language. Participants were trained on an individualized script twice per week, over 8 weeks. Performance on measures related to script accuracy, content, and subjective ratings of production quality was evaluated at baseline, immediately post, and at 3 and 6 months post-intervention.
Results: No significant differences were observed on the basis of intervention modality. Participants demonstrated significant improvements from pre- to post-intervention in script production, synonym production, keywords, and global quality on the trained script. Maintenance was observed when comparing performance at post-intervention relative to 3- and 6-month follow-up for script and synonym production. Significant improvement in production quality of the untrained topic was observed following intervention. Different patterns of benefit were observed by PPA variant.
Conclusions: Modified VISTA was acceptable and effective across the three PPA variants, as evidenced by improvements on a broader array of outcome measures than those previously reported. Findings also provide further support for provision for teletherapy in individuals with PPA.

Objective: In the course of the EU funded Pandemic Preparedness and Response (PANDEM-2) project, a functional exercise (FX) was conducted to train the coordinated response to a large-scale pandemic event in Europe by using new IT solutions developed by the project. This report provides an overview of the steps involved in planning, conducting, and evaluating the FX.
Methods: The FX design was based on the European Centre for Disease Prevention and Control (ECDC) simulation exercise cycle for public health settings and was carried out over 2 days in the German and Dutch national public health institutes (PHI), with support from other consortium PHIs.
SP-DTI: Subpocket-Informed Transformer for Drug-Target Interaction Prediction.

School of Engineering, Westlake University, Hangzhou, 310024, China.
Motivation: Drug-target interaction (DTI) prediction is crucial for drug discovery, significantly reducing costs and time in experimental searches across vast drug compound spaces. While deep learning has advanced DTI prediction accuracy, challenges remain: (i) existing methods often lack generalizability, with performance dropping significantly on unseen proteins and cross-domain settings; (ii) current molecular relational learning often overlooks subpocket-level interactions, which are vital for a detailed understanding of binding sites.
Results: We introduce SP-DTI, a subpocket-informed transformer model designed to address these challenges through: (i) detailed subpocket analysis using the Cavity Identification and Analysis Routine (CAVIAR) for interaction modeling at both global and local levels, and (ii) integration of pre-trained language models into graph neural networks to encode drugs and proteins, enhancing generalizability to unlabeled data.

Sex determination systems are diverse in echinoderms, however, our understanding is still very limited in this research field, especially for Asteroidea species. The northern Pacific seastar, Asterias amurensis, has attracted widespread concern due to its population outbreaks and high-risk invasions. Using whole-genome re-sequencing data from 40 females and 40 males, we identified a candidate sex determination region in A.

Quantifying axons and myelin is essential for understanding spinal cord injury (SCI) mechanisms and developing targeted therapies. This study proposes and validates an automated method to measure axons and myelin, applied to compare contusion, dislocation, and distraction SCIs in a rat model. Spinal cords were processed and stained for neurofilament, tubulin, and myelin basic protein, with histology images segmented into dorsal, lateral, and ventral white matter regions.
