AI in healthcare needs patient-centred regulation to avoid discrimination – new commentary




SAGE





New commentary published in the Journal of the Royal Society of Medicine warns that current risk-based regulatory approaches to Artificial Intelligence (AI) in healthcare fall short in protecting patients, potentially leading to over- and undertreatment as well as discrimination against patient groups.

The authors found that while AI and machine learning systems can enhance clinical accuracy, concerns remain over their inherent inaccuracy, opacity, and potential for bias which are not adequately addressed by the current regulatory efforts introduced by the European Union’s AI Act.

Passed in 2025, the AI Act categorises medical AI as "high risk" and introduces strict controls on providers and deployers. But the authors argue this risk-based framework overlooks three critical issues: individual patient preferences, systemic and long-term effects of AI implementation, and the disempowerment of patients in regulatory processes.

“Patients have different values when it comes to accuracy, bias, or the role AI plays in their care,” said lead author Thomas Ploug, Professor of Data and AI Ethics at Aalborg University, Denmark. “Regulation must move beyond system-level safety and account for individual rights and participation.”

The authors call for the introduction of patient rights relating to AI-generated diagnosis or treatment planning, including the right to:

  • request an explanation;
  • give or withdraw consent;
  • seek a second opinion; and
  • refuse diagnosis or screening based on publicly available data without consent.

They warn that without urgent engagement from healthcare stakeholders - including clinicians, regulators, and patient groups - these rights risk being left behind in the rapid evolution of AI in healthcare.

“AI is transforming healthcare, but it must not do so at the expense of patient autonomy and trust,” said Professor Ploug. “It is time to define the rights that will protect and empower patients in an AI-driven health system.”

Technology and data will save lives: Analytics can help deliver improved healthcare - new book



Carnegie Mellon University





Lives could be saved and treatment times cut, with data-driven decision-making, according to the book, written by an international team.  Analytics Edge in Healthcare, was written for health professionals, policymakers and decision-makers, by Holly Wiberg from Carnegie Mellon University’s Heinz College of Information Systems and Public PolicyAgni Orfanoudaki from the University of Oxford and their former academic supervisor, Dimitris Bertsimas, Vice Provost for Open Learning and Associate Dean of Business Analytics at MIT Sloan School Of Management.

"We have taught analytics in different executive environments and have seen first-hand the power of equipping industry domain experts with these tools to solve real-world problems. We want to bring this education into healthcare. And given the unique opportunities and challenges in the clinical setting, we saw a need to develop a new resource that introduces these methods in context, with tailored approaches and examples," said Wiberg. 

"Our goal in writing this book was to bridge that gap. Every case study we present stems from our own research and collaborations in the field. These examples show how analytics can drive meaningful change in healthcare settings—and this book is our way of helping bring that vision to life," Orfanoudaki continued. 

While many concerns have been voiced about the perceived detrimental impact of AI, on jobs and on consumers’ experience, the team argues there is much to gain, for patients and clinicians, through the use of AI in healthcare management.

Not only could technology manage more effectively hospital bed and appointment allocation, potentially easing squeeze points in the system, but the use of data would result in improved treatment and better health outcomes.

The book includes case studies spanning clinical and operational applications with demonstrated practical impact. "Take transplant care in the U.S.—data-driven techniques helped the national transplant agency improve the fairness and efficiency of organ allocation. That translated into lives saved each year," said Orfanoudaki. 

The team explained how these methods can also be used for care efficiency - with managing bed allocation or capacity managing.

"Optimisation and machine learning are being used to solve these classic operations problems that are not directly clinically oriented, but have far reaching implications for how smoothly a hospital runs, which impacts a patient’s experience and outcomes," Wiberg said.   

The book is packed with examples of how analytics have helped healthcare management, largely drawn from the author team’s own work with collaborators across various health systems. The authors attribute their successful track record to these clinical partnerships, and they hope their book will enable similar opportunities for other teams.


Using data and AI to create better health care systems

Academic medical centers could transform patient care by adopting principles from learning health systems principles, according to researchers from Weill Cornell Medicine and the University of California, San Diego. In this approach, information from electronic health records, clinical trials and day-to-day hospital operations is analyzed in real-time to uncover insights that continuously improve patient care.

The perspective, published June 17 in npj Health Systems, reasons that a smarter, more efficient and more equitable model of care can be created by harnessing existing data to support system-wide learning. Yet, adoption of this model remains limited.

“Integrating diverse databases is part of creating a dynamic health care system,” said lead author Dr. Peter Steel, associate professor of clinical emergency medicine at Weill Cornell Medicine and an emergency medicine physician at NewYork-Presbyterian/Weill Cornell Medical Center. “Practitioners will be able to more easily and quickly see what’s working and what’s not; and what’s driving up unnecessary costs.”

Also, contributing to the perspective are Dr. Robert Harrington, the Stephen and Suzanne Weiss Dean of Weill Cornell Medicine, and Dr. Christopher Longhurst and Dr. Gabriel Wardi, both from the University of California, San Diego.

The authors say establishing a learning health system is especially important now as academic institutions are facing financial strain caused by rising research costs, declining margins and growing patient expectations. The perspective is a call to action for academic health centers to make systemic changes by rethinking how they generate and apply knowledge.

Barriers to Implementation

The idea behind this approach is not new—medical researchers first envisioned learning health systems when hospitals transitioned from paper to electronic health records. However, electronic health records were designed primarily for the convenience of clinicians and patients, rather than for researchers and quality improvement initiatives. Data siloes further complicate establishing learning health systems. Information—patient histories, lab results, imaging or billing records—is stored in separate, disconnected systems that don’t communicate with each other.

Consequently, it can often take years to gather and analyze data needed to improve patient care, the authors noted. A functioning learning health system could shrink this time frame to weeks while maintaining ethical, patient-centric research and using strong security systems to ensure patient privacy. Those insights can then be used to revise treatment guidelines, enhance patient safety and spur innovations.

Part of the issue, the authors argue, is insufficient integration between the people focused on clinical care, research and education. Ideally, future doctors could be taught how to use data to efficiently ask and answer clinical questions that will bring together different stakeholders to collaborate.

“A learning health system, powered by AI, has the potential to elevate clinical care and outcomes,” said Dr. Harrington. “When we enable future clinicians to learn from every clinical encounter, we can improve quality and effectiveness in ways we couldn't before.”

Beyond data organization and analysis, the cost of implementing a learning health system may reach tens of millions of dollars. But the long-term return may be strategic: Years after implementation, health care organizations that successfully utilize this approach could become significantly more competitive than those that do not, the authors said.

Artificial Intelligence is Driving Change

Despite the challenges, the recent advances in artificial intelligence make learning health systems adoption more critical. Patients are starting to expect doctors to leverage AI to deliver personalized, proactive care, but AI depends on clean, well-structured, real-world data. “AI can only fulfill its promise if it’s built on a foundation of learning infrastructure,” Dr. Steel said.

AI tools can analyze huge volumes of medical data quickly, helping doctors spot early warning signs of illness, streamline operations and make faster, more individualized decisions. A learning health system enables essential quality control, ensuring AI tools are continuously monitored for safety, bias and effectiveness.

“Academic medical centers face a rapidly changing funding landscape, even as the costs of technological transformation and administration in health care continue to rise,” Dr. Steel said. “Implementing the learning health system is no longer a theoretical goal, but a strategic imperative.”

Niigata, Japan— In a remarkable advancement for soil science, researchers from Japan have developed a novel method for estimating microbial biomass using water-extractable organic matter (WEOM) from air-dried soils. This innovative approach not only simplifies the estimation process but also eliminates the need for toxic solvents typically used in traditional methods, such as chloroform fumigation extraction.

A research was conducted by a dedicated team from Niigata University, Kyushu University, Japan Atomic Energy Agency, and Anhui Academy of Agricultural Sciences researchers. The study analyzed 50 soil samples from ten diverse profiles across various regions in Japan, including six forests and one pasture. The researchers aimed to evaluate the relationship between WEOM measurements and microbial biomass, focusing on both carbon and nitrogen content.

The findings revealed a strong correlation between the amount of water-extractable organic carbon obtained from air-dried soils and microbial biomass carbon, with a squared correlation coefficient (R2) of 0.94 and a statistical probability (P) of less than 0.01. This indicates that WEOM can serve as a reliable estimate of microbial biomass, particularly for carbon content, which is crucial for understanding soil health and ecosystem functioning.

Moreover, the study highlighted that the relationships between WEOM and microbial biomass carbon were consistent with soil physicochemical properties, achieving an R2 of 1.00 and a root mean square error (RMSE) of just 0.04. In contrast, the correlation between water-extractable total nitrogen and microbial biomass nitrogen was weaker, with an R2 and RMSE of 0.73 and 0.28, respectively. This discrepancy was attributed to differences in inorganic nitrogen compounds present in the soil extracts.

Dr. Hirohiko Nagano, one of the lead researchers, stated, “This new method allows microbial biomass to be estimated from archived air-dried soil samples, even when fresh soil is unavailable. Furthermore, it can also be applied in environments where hazardous chemicals are restricted, since it does not require the use of toxic substances. As a result, we expect that this approach has the potential to dramatically accelerate the construction of large-scale datasets on soil microbial biomass."

The implications of this research are profound. By utilizing air-dried soils, researchers can avoid the complexities and hazards associated with traditional methods, making microbial biomass estimation more accessible and practical for a wider range of studies. This method not only enhances our understanding of soil microbiology but also paves the way for more sustainable practices in environmental research and agriculture.

Prof. Syuntaro Hiradate another member from the research team further emphasized the broader impact of this research, saying, "The ability to estimate microbial biomass without the need for fresh samples or toxic solvents opens new avenues for research in remote or sensitive environments. This could lead to a better understanding of microbial roles in various ecosystems and inform conservation efforts."

While the authors caution that this method remains an empirical estimation requiring further validation across diverse soil samples, the potential for this innovative approach to transform soil science is undeniable. Future research will be essential to confirm its applicability in different soil types and environmental conditions.

This ground-breaking method for estimating microbial biomass represents a significant step forward in soil science, providing researchers with a safer and more efficient tool for studying the vital role of microorganisms in soil health and ecosystem dynamics. As the scientific community continues to explore the potential of WEOM, this study marks a pivotal moment in the mission for sustainable and effective soil management practices.

Osaka, Japan – The capacity to grieve for dying loved ones was long considered a uniquely human ability. But now, researchers from Japan have shown that humans are less unique in this respect than once thought.

In a study published in Primates, researchers from The University of Osaka showed that Japanese macaques exhibit human-like responses to the deaths of their adult companions.

Japanese macaques live in large and highly complex social groups, and their social behaviors have been studied for decades. Despite this, observations of the macaques’ responses to death have been hard to come by except for mothers who carrying their dead infants for a while. Researchers at The University of Osaka had several unprecedented opportunities to make detailed observations of the reactions of individual free-ranging macaques their dying and dead companions. They showed that some macaques tended to remain near, and even repeatedly groom, the corpses of individuals that they had spent much quality time with while alive.

“It’s incredibly rare to document these kinds of behaviors in wild animals,” says lead author of the study Masayuki Nakamichi. “By tracking which individuals were near the deceased and recording their behaviors, we were able to show that their reactions to death were significantly influenced by social bonds.”

Obvious injury or infestation seemed to be a strong deterrent to physical contact, whereas more subtle signs of decline were less likely to affect social interactions. In particular, many macaques clearly avoided the presence of maggots in both dying and dead individuals. However, the researchers recorded one case where social bonds triumphed over this aversion—one alpha female not only remained near her dying grooming partner, but also picked maggots off his back and ate them.

“The fact that some individuals remained near deceased companions they had close relationships with suggests that these macaques have emotional capacities that resemble human compassion,” says Kazunori Yamada, co-author of the study. “It shows that strong social bonds can affect the behavior of macaques, even after death.”

Whether social bonds affect the way to interact with dying and dead companions in other non-human primates remains uncertain. “More observations of death-related events in more species will be needed to fully understand the emotional responses of non-human primates to the dead,” says Nakamichi.

A groundbreaking study has revealed that small but mighty zooplankton—including copepods, krill, and salps—are key players in the Southern Ocean’s ability to absorb and store carbon. 

Led by an international team of researchers, and published in Limnology and Oceanography, the study quantifies for the first time how these tiny creatures collectively enhance carbon sequestration through their seasonal, vertical migrations.

The Southern Ocean is a key region for carbon storage. Traditional thinking is that the carbon storage in the Southern Ocean is dominated by gravitational sinking of detritus produced by large zooplankton grazers, such as krill.

This new research concerns another more recently described process called the ‘seasonal migrant pump’. This process sees zooplankton migrate each year from surface waters to depths below 500m, storing carbon via their respiration and mortality during this deep overwintering phase.

This figure shows the traditional view of how zooplankton transport carbon to depth (left panel) by eating phytoplankton in surface waters in summer, whereby their waste material (Particulate Organic Carbon, POC) sinks passively to great depth, thereby storing the carbon for thousands of years. This new study shows that a winter process known as the ‘seasonal migrant pump’ also leads to a substantial deep carbon storage (right panel). The zooplankton migrate downwards in autumn to overwinter below 500m where their respiration and death directly inject around 65 million tonnes of carbon annually into the deep ocean.

The team first built a big database of zooplankton collected in thousands of net hauls from around the Southern Ocean, dating from the 1920s to the present day. From these they quantified the extent of the zooplankton’s annual descent to overwinter at great depths, where they respire CO2 - directly and efficiently injecting carbon into the deep ocean.

Key Findings:

•    65 Million Tonnes of Carbon Stored Annually: The seasonal, vertical migration of zooplankton transports roughly 65 million tonnes of carbon to depths below 500 meters. 
•    Copepods Dominate the ‘Seasonal Migrant Pump’: Mesozooplankton (mainly small crustaceans called copepods) account for 80% of this carbon flux, while krill and salps contribute 14% and 6%, respectively. 
•    Climate Implications: The Southern Ocean is a critical carbon sink, but current Earth System Models overlook this zooplankton-driven process. As warming shifts species distributions (e.g., declining krill, increasing copepods, changing food sources), the carbon storage dynamics may change dramatically.

Why does the ‘Seasonal Migrant Pump’ matter:

The Southern Ocean absorbs approximately 40% of all human-made CO₂ taken up by oceans, yet the role of zooplankton has been underestimated. Unlike sinking detritus, which removes both carbon and essential nutrients like iron, migrating zooplankton efficiently inject carbon into the deep ocean while recycling nutrients near the surface. This ‘Seasonal Migrant Pump’ could become even more important as marine ecosystems respond to climate change.

Dr Guang Yang, first author and Marine Ecologist from Institute of Oceanology, Chinese Academy of Sciences, said: “Our work shows that zooplankton are unsung heroes of carbon sequestration. Their seasonal migrations create a massive, previously unquantified carbon flux—one that models must now incorporate."

Prof. Angus Atkinson MBE, co-author and Senior Marine Ecologist at Plymouth Marine Laboratory, added: “This study is the first to estimate the total magnitude of this carbon storage mechanism. It shows the value of large data compilations to unlock new insights and to get an overview of the relative importance of carbon storage mechanisms."

Dr Katrin Schmidt, co-author and Marine Ecologist at the University of Plymouth, said: “The study shows the 'seasonal migrant pump' as an important pathway of natural carbon sequestration in polar regions. Protecting these migrants and their habitats will help to mitigate climate change."

Dr Jen Freer, co-author and Ecological Modeller at the British Antarctic Survey (BAS), added: “Krill are famous for their role in the Antarctic food web, but we find that copepods significantly dominate carbon storage overwinter. This has big implications as the ocean warms and their habitats may shift."

This research stresses the urgent need for updates to climate models to include zooplankton-driven carbon fluxes. It also highlights the necessity to manage and protect Southern Ocean ecosystems, where industrial fishing and warming threaten krill populations - a key species that supports both carbon export and Antarctica’s unique biodiversity.

This international study was a collaboration among scientists from China, UK, and Canada, and leverages a century’s worth of data on zooplankton biomass, distribution, respiration and mortality across the Southern Ocean.
