·        AI-enhanced reconstruction of the 12-lead electrocardiogram via 3-leads with accurate clinical assessment | npj Digital Medicine (nature.com) - This article presents an artificial intelligence (AI) algorithm developed to reconstruct a full 12-lead electrocardiogram (ECG) using only 3 leads - two limb leads (I and II) and one precordial lead (V3). The algorithm was trained on over 600,000 clinically acquired ECGs. When evaluated, the reconstructed 12-lead ECGs showed high correlation with the original ECGs. An automated algorithm for detecting acute myocardial infarction performed similarly well on the reconstructed and original ECGs. Additionally, when interpreted by cardiologists, the reconstructed ECGs achieved comparable accuracy to original ECGs in identifying ST-segment elevation myocardial infarction. The researchers suggest this approach could enable ECG acquisition with simplified tools in non-specialized settings, potentially facilitating diagnosis of heart conditions outside traditional clinical environments. However, they note further validation through prospective clinical trials is needed to evaluate real-world performance and clinical utility. Overall, this work represents a step towards more accessible cardiac diagnostics using AI and limited-lead ECG data.

While further validation is needed, the authors believe this cloud-based AI approach has the potential to improve neonatal care globally by enabling rapid, accurate assessment of HIE severity and prognosis, even in resource-limited settings. They emphasize that ethical implementation of such AI tools could help reduce gaps in healthcare quality between high and low-income regions.

·        Generalization—a key challenge for responsible AI in patient-facing clinical applications | npj Digital Medicine (nature.com) - The article addresses the challenge of generalization in clinical AI applications and proposes selective deployment as a potential solution. Generalization, the ability of AI systems to apply knowledge to new data, is a major challenge for real-world AI applications, especially in healthcare. Poor generalization can result from overfitting, dataset biases, and the complex nature of clinical data. Using a breast cancer prognostic algorithm case study, the authors illustrate the ethical dilemmas of deploying AI systems that may not generalize well to underrepresented groups. They propose selective deployment - using AI only for groups well-represented in training data - as a potential ethical compromise between delaying deployment entirely and risking harm to underrepresented groups. The article discusses technical approaches for implementing selective deployment, including data-centric methods (data curation) and model-centric methods (uncertainty estimation, out-of-distribution detection). The authors explore ethical considerations of selective deployment, acknowledging it could temporarily maintain health disparities but may be the most ethical option in some cases. The authors conclude by calling for more research into improving generalization in clinical ML and encourage exploring sample selection strategies to make clinical AI applications trustworthy and safe for all patients.

·        Hidden flaws behind expert-level accuracy of multimodal GPT-4 vision in medicine | npj Digital Medicine (nature.com) - This article presents a comprehensive evaluation of GPT-4V's performance on medical image challenges from the New England Journal of Medicine. While GPT-4V achieved high accuracy (81.6%) in answering multiple-choice questions, comparable to human physicians in closed-book settings, the study revealed hidden flaws in its reasoning process. The researchers assessed GPT-4V's capabilities in three areas: image comprehension, recall of medical knowledge, and step-by-step reasoning. They found that image comprehension was the most problematic area, with over 25% of cases containing flawed rationales. Surprisingly, even when GPT-4V provided the correct final answer, it often made errors in one or more aspects of its reasoning, particularly in image comprehension (27.2% error rate). The study highlights that while GPT-4V shows promise in medical decision support, especially in cases where physicians struggle, its rationales are not always sound. This underscores the need for thorough evaluation of AI models' reasoning processes before integration into clinical workflows. The researchers emphasize that comprehensive assessments beyond mere multiple-choice accuracy are crucial. They note that human physicians still outperform GPT-4V in open-book settings, particularly for difficult questions. The study concludes by stressing the importance of further in-depth evaluations of multimodal AI models' rationales to ensure their reliability and safety in clinical applications.

The authors envision future bioimage analysis being conducted by intelligent MLLM agents that can assist researchers throughout the entire research process, from experimental design to data analysis and knowledge discovery.

·        Can Large Language Models Provide Useful Feedback on Research Papers? A Large-Scale Empirical Analysis | NEJM AI / Can large language models provide useful feedback on research papers? A large-scale empirical analysis (arxiv.org) - This article presents a large-scale study examining whether large language models (LLMs) like GPT-4 can provide useful feedback on scientific research papers. The study analyzed feedback generated by GPT-4 on over 3,000 papers from Nature journals and 1,700 papers from the ICLR machine learning conference. It found significant overlap between GPT-4's feedback and human reviewer comments, with about 30-40% of GPT-4's comments matching those from individual human reviewers. This level of overlap was comparable to the overlap between different human reviewers. The study also conducted a survey of 308 researchers, finding that over 50% considered GPT-4's feedback helpful for improving their work. However, limitations were noted, including GPT-4's tendency to focus on certain aspects of feedback more than others and sometimes providing less specific comments than human reviewers. The authors conclude that while LLM-generated feedback shows promise as a complementary tool, especially for researchers with limited access to timely expert feedback, it cannot replace thoughtful human expert review in the scientific process.

Overall, this AI approach demonstrates the potential to extract dynamic functional information from static chest x-ray images, potentially adding value to routine radiographs in assessing pulmonary function.

·        Medical artificial intelligence for clinicians: the lost cognitive perspective - The Lancet Digital Health - This article discusses the challenges of integrating artificial intelligence (AI) into clinical decision-making, particularly in radiology. The authors argue that there is a fundamental mismatch between how clinicians and AI systems make decisions. Clinicians use "ecologically bounded reasoning," relying on contextual cues and expertise to make efficient decisions. In contrast, AI systems are "dataset bounded," using any correlations found in training data without necessarily understanding clinical relevance. The paper highlights the risks of this mismatch, including the potential for AI to use irrelevant or spurious correlations in making diagnoses. It critiques current approaches to human-AI interaction in healthcare, such as the concept of "teaming" and the field of explainable AI (XAI), arguing that these do not adequately address the cognitive differences between humans and AI. The authors propose a new framework for studying human-AI interaction in medicine, based on three levels of analysis: behavioral, cognitive, and cognitive model. They argue that research needs to move beyond surface-level observations to understand the complex cognitive processes involved in clinical decision-making with AI. The article concludes by emphasizing the need for a more comprehensive understanding of clinical cognition in the context of AI use, to ensure the safe and effective implementation of AI in healthcare. It calls for research that acknowledges the fundamental differences between human and AI decision-making, and explores the cognitive, environmental, and neurophysiological aspects of human-AI interaction in clinical settings.

The emphasis on rigorous validation, uncertainty quantification, and interpretability is particularly relevant given the high stakes of medical applications. The article's discussion of covariate shift is especially pertinent, as medical training data often comes from controlled studies while real-world application involves more diverse populations. The recommendations on calibrating uncertainties and conducting ablation studies could help produce more robust and trustworthy ML models in medicine. Additionally, the focus on extracting interpretable insights rather than just pursuing high accuracy aligns well with the need for explainable AI in healthcare. Overall, adopting these practices could lead to more reliable and scientifically insightful ML applications in medical research, enhancing the potential for ML to contribute meaningfully to advancing medical knowledge and improving patient care.

·        AI and ethics: Investigating the first policy responses of higher education institutions to the challenge of generative AI | Humanities and Social Sciences Communications (nature.com) - This article examines the initial responses of leading higher education institutions to the ethical challenges posed by generative AI tools like ChatGPT. The authors analyzed policy documents and guidelines from 30 top universities worldwide, focusing on four key ethical principles derived from international AI ethics frameworks: accountability and responsibility, human agency and oversight, transparency and explainability, and inclusiveness and diversity. The study found that universities generally aim to explore AI's potential benefits while addressing emerging challenges. A common theme is that students must complete assignments based on their own knowledge, with human individuals retaining moral and legal responsibility. Many institutions adopt a decentralized approach, allowing instructors flexibility in determining AI use in their courses while requiring clear communication of policies. Best practices identified include combining preventive measures with soft, dialogue-based procedures for oversight, providing clear guidelines on permissible AI use, and offering centralized resources to ensure equal access and support for all students. The authors note that early responses often drew from traditional AI ethics frameworks rather than academic literature, as institutions sought to quickly address the rapid emergence of powerful generative AI tools in education. The paper concludes that while universities are actively grappling with these ethical challenges, approaches vary and will likely continue to evolve as understanding of AI's impacts on higher education deepens. It suggests further research to track how institutional policies develop over time in response to advancing AI capabilities.
