Machine perfusion is an emerging and transformative technology for dynamic organ preservation, assessment and repair. Whereas allografts continuously degrade during static cold storage, short-term perfusion can preserve high-quality organs for hours, enabling assessment, regional transport and improved logistics. Long-term perfusion for multiple days might extend the potential of clinical machine perfusion in the future, allowing for the assessment, reconditioning and repair of marginal or injured grafts for which more time is needed. In addition, it might convert transplantation, which is now semi-elective thanks to short-term perfusion, to a fully elective procedure via customized machines and associated protocols that maintain organs ex situ for up to 2 weeks. The advent of long-term organ perfusion provides tremendous potential to improve organ evaluation and selection, to recondition or repair marginal grafts and, ultimately, to expand the pool of grafts available for transplantation. In this Perspective, we discuss design considerations, guidelines for use, and future perspectives of machine perfusion in the context of organ assessment and repair, with a focus on the liver. In this Perspective article, Huwyler, Binz and colleagues discuss the future of long-term normothermic machine perfusion for livers and propose a staged assessment approach for ex situ perfused organs.

Clinical decision making in gastroenterology and hepatology has become increasingly complex and challenging for physicians. This growing complexity can be addressed by computational tools that support clinical decisions. Although numerous clinical decision support systems (CDSS) have emerged, they have faced difficulties with real-world performance and generalizability, resulting in limited clinical adoption. Generative artificial intelligence (AI), particularly large language models (LLMs), are introducing new possibilities for CDSS by offering more flexible and adaptable support that better reflects complex clinical scenarios. LLMs can process unstructured text, including patient data and medical guidelines, and integrate various information sources with high accuracy, especially when augmented with retrieval-augmented generation. Thus, LLMs can provide dynamic, context-specific support by generating personalized treatment recommendations, identifying potential complications based on patient history, and enabling natural language interactions with health-care providers. However, important challenges persist, particularly regarding biases, hallucinations, interoperability barriers, and proper training of health-care providers. We examine the parallel evolution of the complexity in clinical management in gastroenterology and hepatology, and the technical developments leading to current generative AI models. We discuss how these advances are converging to create effective CDSS, providing a conceptual basis for further development and clinical adoption of these systems. This Perspective discusses the use and potential of large language models and clinical decision support systems in gastroenterology and hepatology, highlighting opportunities, challenges and limitations of large language models and clinical decision support systems in clinical practice. Key directions for research and insights into clinical integration and safe use are also discussed.

The microbiome has critical roles in human health and disease. Advances in high-throughput sequencing and metabolomics have revolutionized our understanding of human gut microbial communities and identified plausible associations with a variety of disorders. However, microbiome research remains constrained by challenges in establishing causality, an over-reliance on correlative studies, and methodological and analytical limitations. Artificial intelligence (AI) has emerged as a powerful tool to address these challenges; however, the seamless integration of preclinical models and clinical trials is crucial to maximizing the translational impact of microbiome studies. This manuscript critically evaluates best methodological practices and limitations in the field, focusing on how emerging AI tools can bridge the gap between microbial insights and clinical applications. Specifically, we emphasize the necessity of rigorous, reproducible methodologies that integrate multiomics approaches, preclinical models and clinical trials in the AI-driven era. We propose a practical framework for applying AI to microbiome studies, alongside strategic recommendations for clinical trial design, regulatory pathways, and best practices for microbiome-based informed diagnostics, AI training and clinical interventions. By establishing these guidelines, we aim to accelerate the translation of microbiome research into clinical practice, enabling precision medicine approaches informed by the human microbiome. Artificial intelligence (AI) is a powerful tool that could be applied to microbiome research. This Perspective discusses best practices and current limitations with the application of AI in microbiome data research, giving insights into future use and practical advice and recommendations on its use.

As the global population ages, research on the biology of ageing and its role in chronic disease is expanding, alongside a growing clinical focus on the unique needs of older adults. In the past, the liver was not thought to undergo substantial age-related changes, nor was there thought to be any liver disease characteristic of older adults. Current studies challenge this perspective, revealing that ageing substantially influences liver pathophysiology at the organ level and within each of the liver cell types. These observations have implications for understanding the pathogenesis of liver diseases common in older adults, including hepatocellular carcinoma, hypoxic hepatitis and metabolic dysfunction-associated steatotic liver disease. Previously, managing older patients with liver disease mostly addressed age-related changes in drug metabolism and liver function tests. However, current clinical practice increasingly emphasizes age-specific issues such as frailty, sarcopenia, multimorbidity and polypharmacy. Given the liver’s pivotal role in systemic metabolism, immunity and detoxification, ageing of the liver can contribute to systemic diseases. In the future, interventions that target ageing biology might offer new treatment options for liver diseases. Here, we review those age-related changes in the liver that have substantial biological and clinical consequences for older adults. Older adults can be affected by multiple chronic medical conditions, including liver disease. This Review provides a comprehensive overview of age-related pathophysiological changes in the liver and discusses interventions and treatment options for older patients.
