GPT-4-generated, accessibility-optimised discharge letters increased comprehension of diagnosis, treatment, investigations and follow-up compared with conventional letters.

In two controlled quasi-experimental studies published 12 September 2026, 341 online-recruited adults and 791 medical and nursing students at the University of Turin were assigned to read either a GPT-4-generated accessibility-optimised discharge letter or a traditional discharge letter. Comprehension was measured with a structured score covering diagnosis, treatment, investigations and follow-up, with secondary measures of readability, clarity and satisfaction.

Standardizing pre-analytical H&E preparation before AI deployment can reduce computational burden and deployment costs while supporting robust AI performance in pathology.

A peer-reviewed analysis of French national external quality assessment data from 2019-2024 and a 2024 survey found frequent H&E preparation issues: up to 25.5% of slides had technical imperfections such as sectioning, thickness, and stretching problems, and 8.3% to 23.8% had suboptimal staining with poor nucleo-cytoplasmic contrast or intensity fluctuations.

Machine learning-based risk zoning using integrated biological and abiotic indexes improved fit and classification, with CFBRI raising R2 to 0.62 and Random Forest models reaching cross-validation accuracies of 0.888 for agricultural land and 0.905 for construction land.

Researchers proposed a framework that integrates biological and non-biological indicators for soil heavy metal risk assessment. They developed a CRITIC-Fuzzy Biomarker Response Index to weight multi-timepoint biomarker data, then combined it with four abiotic pollution indices via PCA to create agricultural and construction land comprehensive indexes, which were used as labels to train five machine learning classifiers.

Systematic review found most ML algorithms improved CVD risk prediction compared with Framingham Risk Score by incorporating sociodemographic predictors and modeling non-linear interactions.

A systematic review published 12 September 2026 searched three databases to 1 January 2025 and included 29 studies that directly compared machine learning CVD risk predictions with the Framingham Risk Score in healthy adults. Twenty-three studies reported improved predictive ability, often by adding sociodemographic predictors absent from FRS or costly diagnostics such as CT angiography.

Despite belief AI will revolutionise nursing education, actual implementation remains conservative at augmentation level with none achieving transformative redefinition.

A scoping review published August 15, 2026 examined how nursing academics perceive and use AI in nursing education, synthesizing 15 studies from eight countries with 2004 academics. It found most believe AI will revolutionise education but actual use is selective and conservative, concentrated at the augmentation level for productivity and research writing rather than assessment or transformative pedagogy.

ML applications in clinical microbiology face typical challenges including class imbalance, limited generalization, robustness issues, and need for model interpretation and explainability to achieve robust performance under real-world variability.

Published August 15, 2026, this narrative review in Clinical Microbiology and Infection introduces the machine learning lifecycle from a clinical microbiology perspective, covering data preparation, model development, evaluation, and deployment, drawing on applied research and AI development guidelines for healthcare.

Models that were near-perfect during internal cross-validation diverged significantly on the separate external cohort, showing reduced out-of-distribution generalization for cross-species histological classification.

On 2026-08-16, a peer-reviewed study reported a comparative evaluation of nine deep learning encoders for H&E histology classification. Models were trained on 4307 male rat tissue images and tested on a separate 600-image mixed human-and-animal cohort using frozen features and a linear probe, measuring accuracy, F1, kappa, ROC-AUC and inference time.
