Body–machine interfaces (BoMIs) are promising tools for trunk rehabilitation, as they can provide real-time feedback on user movements and muscle activity, allowing for continuous monitoring and guidance during motor control training. However, research on BoMIs for trunk rehabilitation is limited, and current methods often lack precision in addressing trunk muscle deficits. This work introduces a BoMI that combines trunk electromyography (EMG) and motion data to selectively modulate trunk muscle activity during motor control tasks. The system utilizes machine learning to generate personalized trunk motion trajectories based on predefined EMG profiles. Each trajectory is displayed on a screen as a moving target, which users must follow by controlling the BoMI with their trunk movements. We hypothesize that by visually guiding users to track these generated trajectories, the BoMI could evoke the EMG patterns implicitly encoded within them. Tested with neurotypical individuals, the BoMI effectively elicited the desired trunk EMG profiles, achieving a mean similarity index of 0.82 ± 0.13, a correlation coefficient of 0.95 ± 0.03, and minimal timing mismatches. These results support the feasibility of using an EMG-based BoMI for precise trunk muscle training, which could potentially assist therapists in more efficiently monitoring and adjusting patients’ muscle engagement during interventions. Future work will focus on developing a control framework to dynamically adapt task difficulty to users’ needs, expanding the approach to include additional trunk muscles, and evaluating its translation to individuals with trunk muscle impairments.</div></div>","PeriodicalId":13953,"journal":{"name":"Informatics in Medicine Unlocked","volume":"56 ","pages":"Article 101641"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143922413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current Deep Learning (DL) approaches for automated cervical cytology classification encounter challenges such as class imbalance, computational inefficiency, and inadequate generalizability. This study proposes a novel CerviXEnsemble model that integrates multiple pre-trained DL architectures (Inception-ResNetV2, EfficientNet-B6, ResNet152, Inception-ResNetV2, EfficientNet-B6, DenseNet201, and NASNetMobile) as base learners, along with a dense-layer meta-learner that refines and consolidates predictions for improved robustness. Unlike traditional single-CNN models, our stacking ensemble approach utilizes diverse feature representations to enhance classification stability and generalization across multiple cytology datasets. To validate the model, we experimented with the Herlev and SIPaKMeD benchmark datasets in this study. Techniques like contrast enhancement and data augmentation were employed to optimize feature extraction. The model achieved state-of-the-art performance, attaining an accuracy of 99.38 % and an F1-score of 98.49 % on the Herlev dataset and an accuracy of 98.71 % and an F1-score of 97.53 % on SIPaKMeD. These performances are superior to previous studies in controlling class imbalance and providing stable predictions over different samples. Additionally, Explainable AI (XAI) techniques were incorporated to ensure transparent and interpretable predictions, aiding clinicians in their decision-making processes. An interpratable web application was developed for real-time Pap smear analysis to reduce the diagnostic workload for pathologists by identifying high-risk samples. This solution shows great promise for use in various healthcare settings, maintaining high diagnostic accuracy while requiring minimal computational resources, making it suitable for both urban hospitals and rural clinics.</div></div>","PeriodicalId":13953,"journal":{"name":"Informatics in Medicine Unlocked","volume":"56 ","pages":"Article 101657"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144138953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We deploy several Artificial Intelligence (AI) techniques to derive COVID-19 severity classification prognosis models for unvaccinated patients hospitalized with mild symptoms using immunological biomarkers. The risk levels are precisely defined, targeting patients with uncertain prognostic trajectories. Forty molecular biomarkers were evaluated for their ability to predict the course of the illness. Seven biomarkers, including IL-6, IL-10, CCL2, LDH, IFNα, ferritin, and anti-SARS-CoV-2 N protein IgA antibody, emerge as the most significant early predictors for the prospective development of severe disease. After applying feature selection, we settled for two complete sets of five and three biomarkers to generate appropriate classification models. A Random Forest model with five biomarkers appears to be the most effective, with an accuracy of 0.92 for the external set. Yet, a Decision Tree model with just three biomarkers, and an accuracy of 0.84 for the external set, provides marginally lower yet robust performance and an explainable structure that broadly reflects our current understanding of disease severity. These findings suggest that the severity is influenced by a few key pathological processes.
