HARU-Net: hybrid attention residual U-Net for edge-preserving denoising in cone-beam computed tomography
This study proposes HARU-Net, a hybrid attention residual U-Net trained on a cadaver dataset of human hemimandibles acquired with a high-resolution cone-beam computed tomography (CBCT) protocol for low-dose CBCT denoising; the architecture embeds a hybrid attention transformer block within each skip connection, a residual hybrid attention transformer group at the bottleneck, and residual learning convolutional blocks, and reports the highest peak signal-to-noise ratio of 37.52 dB, the second-highest SSIM of 0.9557, and the lowest GMSD of 0.1084, while maintaining substantially lower computational complexity than transformer-based methods.
Fine-Tuning, Retrieval-Augmented Generation, and Hybrid Adaptation of Language Models for Clinical Decision-Making in Health Care: Systematic Review
Following PRISMA 2020 guidelines and searching PubMed/MEDLINE, Scopus, and Web of Science (January 2018 through May 2026), this systematic review screened 1890 records and included 35 studies published between 2024 and 2026, grouping them into fine-tuning or parameter-efficient fine-tuning (7/35, 20%), retrieval-augmented generation (17/35, 48.6%), and hybrid approaches (11/35, 31.4%) for descriptive synthesis, finding that fine-tuning performed strongly on narrow task-specific applications (area under the receiver operating characteristic curve up to 0.912 for cancer detection and area under curve 0.892 for major depressive disorder prediction), that retrieval-augmented generation improved guideline adherence and diagnostic accuracy (from 71.1% to 92.1% and from 78.9% to 94.
A Guide to Building Efficient QA Systems for Medical Use: Helping Patients Gather Reliable Information
This study proposes a method that builds a schizophrenia QA dataset from publicly accessible online health forums using Topic-guided Semantic Modeling (TGSM) and a two-stage Retriever-Reader pipeline, yielding 415,602 posts, 35 topics, and 1,050 QA pairs, and shows that BioBERT fine-tuned on this dataset outperforms its base version and lighter baselines such as DistilBERT on precision and exact match.
Survey of Acceptance and Requirements for AI Ambient Scribe Systems in German Ophthalmology
This study anonymously surveyed 34 ophthalmologists (median age 49 years, 47% female) from a regional physician network in Germany via online questionnaire and found that most respondents spent 20–39% of their working time on clinical documentation, approximately three quarters expressed general interest in using a reliable and secure ambient scribe system, key perceived benefits were reduced documentation time and increased time for patient care, major barriers were concerns about AI reliability, integration into existing IT systems and data protection, with locally deployed solutions preferred over cloud-based approaches.
Toward AI Virtual Cells for Hepatology: Representation, Generation, Dynamics, and Intervention in Single-Cell Models
This review organizes current work toward an AI Virtual Cell (AIVC) for the liver into three complementary modeling routes—generative models that represent cell states, dynamics and transport models that infer state transitions, and pretrained or foundation models that test whether learned representations transfer across donors, etiologies, disease stages, and platforms—with perturbation-response prediction as a cross-cutting assessment, concluding that published models demonstrate only individual components such as atlas integration, inferred trajectories, transferable representations, and retrospective response programs, and do not yet constitute a prospectively validated liver simulator, so near-term use should prioritize experiment selection and hypothesis generation while clinical dec
A Medically Grounded LLM Agent-Based Tool to Detect Patient Safety Events in Medical Records
The study presents SAFE-AI, a framework that restricts a large language model to zero-shot entity extraction from emergency medical services charts and then makes determinations through a deterministic rule-based computational graph built from a clinician-defined ontology of clinical guidelines, reporting 97.9% accuracy for detecting epinephrine overdose and 91.6% for detecting delays in epinephrine administration across 300 pediatric out-of-hospital cardiac arrest charts containing 18,402 lines of clinical information, outperforming the compared baseline models.
Automated Extraction of Genetic Eligibility Criteria from Clinical Trial Records Using LLMs: A Technical Case Report
This technical case report develops and evaluates a system that combines local large language models with rule-based validation against HUGO Gene Nomenclature to extract and structure mutational eligibility criteria from clinical trial records (identifying mutated genes, distinguishing inclusion from exclusion criteria, and assigning them to individual study arms); applied to 4,918 clinical trials it produced structured representations for 1,010 studies, and expert review of 42 trials showed 88.1% of studies correctly annotated with 80% precision at the level of individual eligibility criteria, with failures mainly due to hallucinated genes and misinterpreted abbreviations.
Optical Diffraction Tomography and Interpretable Machine Learning Reveal Biophysical Signatures of Gametocyte-Stage Malaria in Red Blood Cells
This study combines label-free optical diffraction tomography (ODT) with an interpretable machine-learning framework to extract physically interpretable morphological and biophysical descriptors (sphericity, solidity, eccentricity, dry mass, maximum refractive index) and self-supervised vision transformer (ViT) image representations from three-dimensional refractive index tomograms of red blood cells from synchronized P. falciparum cultures, finding that gametocyte-stage infected RBCs show significantly reduced sphericity and increased eccentricity, with combined features achieving 88.3% accuracy in multiclass classification (normal, ring, gametocyte) and 98.
Mapping Applications of Artificial Intelligence in Social Support for Persons with Disabilities: A Systematic Scoping Review
Following PRISMA-ScR guidelines, this systematic scoping review searched PubMed and Web of Science and identified 72 relevant studies, mapping AI applications in social support for persons with disabilities through the lens of participation, autonomy, and environmental fit across five areas—"Mobility and Navigation Assistance" (n = 20, 41.7%), "Communication and Information Accessibility" (n = 14, 29.2%), "Smart Assistance for Daily Living" (n = 7, 14.6%), "Education and Vocational Empowerment" (n = 5, 8.3%), and "Mental Health Support and Social Inclusion" (n = 3, 6.3%)—and identifying challenges including data privacy (58.3%), inadequate training datasets (25.0%), high implementation costs (25.0%), algorithmic biases (20.8%), and limited real-world evidence of benefits (20.
