Article Abstract
The search for reliable prognostic markers in oral squamous cell carcinoma (OSCC) remains a critical need. Tumor-infiltrating lymphocytes (TILs), particularly T lymphocytes, play a pivotal role in the immune response against tumors and are strongly correlated with favorable prognoses. Computational pathology has proven highly effective for histopathological image analysis, automating tasks such as cell detection, classification, and segmentation. In the present study, we developed a StarDist-based model to automatically detect T lymphocytes in hematoxylin and eosin (H&E)-stained whole-slide images (WSIs) of OSCC, bypassing the need for traditional immunohistochemistry (IHC). Using QuPath, we generated training datasets from annotated slides, employing IHC as the ground truth. Our model was validated on Cancer Genome Atlas-derived OSCC images, and survival analyses demonstrated that higher TIL densities correlated with improved patient outcomes. This work introduces an efficient, AI-powered workflow for automated immune profiling in OSCC, offering a reproducible and scalable approach for diagnostic and prognostic applications.

Genome-scale metabolic models (GEMs) are widely used in systems biology to investigate metabolism and predict perturbation responses. Automatic GEM reconstruction tools generate GEMs with different properties and predictive capacities for the same organism. Since different models can excel at different tasks, combining them can increase metabolic network certainty and enhance model performance.

Online adaptive radiation therapy (ART) personalizes treatment plans by accounting for daily anatomical changes, requiring workflows distinct from conventional radiotherapy. Deep learning-based dose prediction models can enhance treatment planning efficiency by rapidly generating accuracy dose distributions, reducing manual trial-and-error and accelerating the overall workflow; however, most existing approaches overlook critical pre-treatment plan information-specifically, physician-defined clinical objectives tailored to individual patients. To address this limitation, we introduce the multi-headed U-Net (MHU-Net), a novel architecture that explicitly incorporates physician intent from pre-treatment plans to improve dose prediction accuracy in adaptive head and neck cancer treatments.

Purpose: We present a novel protocol for wrist function assessment that integrates both objective factors (range of motion and grip strength) and subjective domains (pain, motor function, and quality of life) into the composite Wrist Function Score - 175 (WFS-175) score.
Methods: The protocol consists of three main steps: (1) data collection, which involves measuring the wrist range of motion in six directions using a goniometer and grip strength, including maximum strength, endurance, and recovery, using a Jamar dynamometer, alongside concurrent subjective assessment with a standardized questionnaire; (2) standardization of all data onto a unified scoring scale, applying a linear formula to calculate the total WFS-175 score (maximum 175 points), with the following components: range of motion (30 points), grip strength (40 points), pain (25 points), motor function (40 points), and quality of life (40 points); and (3) input of results into the AppSheet/Google Sheets system, which provides automated calculation, storage, reporting, and graphical visualization for longitudinal tracking of functional recovery.
Results: This protocol yields a standardized assessment form that enables precise calculation of the WFS-175 score.

Unlabelled: Foundation models, including large language models and vision-language models (VLMs), have revolutionized artificial intelligence by enabling efficient, scalable, and multimodal learning across diverse applications. By leveraging advancements in self-supervised and semi-supervised learning, these models integrate computer vision and natural language processing to address complex tasks, such as disease classification, segmentation, cross-modal retrieval, and automated report generation. Their ability to pretrain on vast, uncurated datasets minimizes reliance on annotated data while improving generalization and adaptability for a wide range of downstream tasks.
