The postoperative complications of medical tourism may be costing the NHS up to £20,000 per patient, suggest the findings of a rapid review of the available data, published in the open access journal BMJ Open.   But data on the use, frequency, and consequences for the NHS are incomplete and haphazard, making it currently impossible to fully understand the risks of opting for surgery overseas, warn the researchers.   The number of medical tourists has risen steadily over the past several decades, ...

Smartphone apps—particularly those based on psychological theories—are 3 times as effective as no/minimal support at helping people who smoke stub out their tobacco use long term, suggests a pooled data analysis of the available evidence, published in the online journal BMJ Evidence Based Medicine.   If high quality clinical trials can confirm lasting benefits and key features, these apps could become a cornerstone of global tobacco control efforts, suggest the researchers.   Smartphone ...

Female sex and higher education are significantly linked to the escalating prevalence of obesity and overweight in Africa, finds one of the largest and most detailed analyses of body weight trends in the region, published in the open access journal BMJ Global Health.   Women’s odds of obesity in Africa are 5 times greater than those of men’s, while obesity is 3 times more likely in those with tertiary level education than in those with lower levels, the findings indicate.   The global prevalence of overweight and obesity has more than doubled over the past 4 decades. In 2022, 2.5 billion adults ...

For the first time, researchers have used machine learning – a type of artificial intelligence (AI) – to identify the most important drivers of cancer survival in nearly all the countries in the world. The study, which is published in the leading cancer journal Annals of Oncology [1] today (Wednesday), provides information on which improvements or policy changes can be made in each country that would have the greatest impact on improving cancer survival. By going to the online tool created by the researchers, anyone can find ...

New findings from the University of East London show that online risk-taking is widespread among young people, with behaviours such as digital piracy, accessing risky online spaces or engaging with harmful content having a high potential to lead to more serious offenses.  Interviews with convicted cybercriminals in the UK and Switzerland revealed a diverse cohort spanning a wide age range and offence types, from hacking and digital fraud to sexual offences carried out online. Nearly half (47%) reported engaging ...

About 20% of U.S. adults experience major depression in their lifetime. For most people, symptoms improve within a few treatment attempts, but up to one-third of patients have treatment-resistant depression, for which standard antidepressant medication or psychotherapy isn’t enough. Now, a study shows that a small, implanted device may provide substantial, long-lasting relief to people with the most severe treatment-resistant depression. Researchers at Washington University School of Medicine in St. ...

A recent publication in Nature Medicine describes a novel immunotherapy targeting pancreatic cancer that has shown promising results in a first in-human phase 1/2 trial.

Marsupials are a group of mammals that encompass many of Australia's most iconic animals, unique because of their geographically isolated evolution. Despite their household names, their microbiomes remain under-researched.   "Understanding marsupial gut microbiomes advances our knowledge of host-microbiome evolution, helps explain adaptations to challenging diets like eucalyptus, and supports conservation efforts for threatened species through improved health management,” says Kate Bowerman, a microbiologist at the University of Queensland (UQ) and co-author ...

Challenging a 50-year-old narrative about Hawaiʻi’s native birds, a new study from the University of Hawaiʻi at Mānoa found no scientific evidence that Indigenous People hunted waterbird species to extinction. Published in the journal Ecosphere, the research debunks this long-held myth and offers a new, integrated theory to explain the disappearances. Researchers found no evidence that Indigenous People over-hunted birds to extinction. Instead, the authors suggest a new theory: the birds died out because of a combination of climate change, invasive species,and changes in how the land was used—most of which happened either prior to Polynesian ...

Biochar has long been promoted as a climate-friendly soil amendment, but new research suggests that treating it as a one-size-fits-all solution may be limiting its full potential. A new open-access review published in Biochar shows that engineered biochar works best when it is carefully customized for specific agricultural and environmental goals, from boosting crop yields to suppressing soil-borne diseases and remediating contaminated land. The international research team reviewed more than a decade of studies on engineered biochar and its interactions in the rhizosphere, the thin zone of soil surrounding ...

A growing body of research suggests that combining enzymes with biochar, a carbon-rich material made from agricultural and organic waste, could transform how scientists clean polluted water and soil. A new review published in Biochar provides the most comprehensive overview to date of how biochar-immobilized enzymes work, why they are effective, and what challenges remain before the technology can be widely applied. Environmental pollution from industrial chemicals, dyes, pharmaceuticals, antibiotics, and heavy metals continues to threaten ecosystems and human health worldwide. Traditional treatment methods often rely on energy-intensive processes or chemical reagents that can ...

Researchers led by Yue Pan at Shenyang Agricultural University tested how swings between wet and dry conditions affect soil organic carbon breakdown in a clay loam Alfisol from Northeast China, and whether biochar can soften these impacts. The team incubated soils for 90 days under three moisture patterns and three levels of corn straw biochar to mimic the more extreme rainfall expected under climate change.​ The study showed that stronger moisture variability sped up soil organic carbon decomposition, increasing cumulative carbon dioxide release by up to 17.2 percent compared with constant moisture. At the same time, fluctuating moisture boosted soil microbial activity and shifted the ...

For decades, global efforts to combat climate change and protect biodiversity have relied on a high-tech promise: that satellite-derived maps can tell us exactly where the world's forests are. But a new study from the University of Notre Dame reveals that these digital baselines are often in sharp disagreement, creating confusion that threatens to undermine effective climate funding and international development efforts. Because these maps determine everything from carbon storage estimates to the enactment of conservation policies, even small discrepancies can have serious ...

As the warning label on every pack of cigarettes tells us, smoking is harmful. It’s the leading preventable cause of death, disease and disability. And yet, nearly 15 percent of adults in the United States still smoke.  “Most indicate they want to quit,” said Jeff Stein, an addiction researcher and assistant professor with Virginia Tech’s Fralin Biomedical Research Institute at VTC. “But knowing that smoking affects your health isn’t enough to motivate people. The future is just too abstract and often doesn’t feel real.” If ...

UNIVERSITY PARK, Pa. — Artificial intelligence (AI) is increasingly used to analyze medical images, materials data and scientific measurements, but many systems struggle when real-world data do not match ideal conditions. Measurements collected from different instruments, experiments or simulations often vary widely in resolution, noise and reliability. Traditional machine-learning models typically assume those differences are negligible — an assumption that can limit accuracy and trustworthiness. To address this issue, Penn State researchers have developed a new artificial intelligence framework with potential implications for fields ranging from Alzheimer’s disease ...

Boulder, Colo., USA: Dr. Rowan Martindale, a paleoecologist and geobiologist at the University of Texas at Austin, was walking through the Dadès Valley in the Central High Atlas Mountains of Morocco when she saw something that literally stopped her in her tracks. Martindale and her colleagues, including Stéphane Bodin of Aarhus University, were trekking through the rocky valley to study the ecology of the ancient reef systems that once sat below sea level there. To get to the reefs, they first had to traverse through layers and layers of turbidites—deposits made by thick submarine ...

BATON ROUGE, La. – Pennington Biomedical researchers recently investigated the systems of the body that regulate weight, exploring whether our bodies defend an established weight target or if our bodies operate within a broader range of tolerance before biological mechanisms are activated. The paper, titled “Body weight regulation models in humans: insights for testing their validity,” which was recently published in Nature Reviews Endocrinology, examined competing body weight regulation models and analyzed how energy intake and expenditure interact ...

Large language models (LLM) can generate treatment recommendations for straightforward cases of hepatocellular carcinoma (HCC) that align with clinical guidelines but fall short in more complex cases, according to a new study by Ji Won Han from The Catholic University of Korea and colleagues publishing January 13th in the open-access journal PLOS Medicine. Choosing the most appropriate treatment for patients with liver cancer is complicated. While international treatment guidelines provide recommendations, clinicians must tailor their treatment choice based on cancer stage and liver function as well as other factors such as comorbidities. To assess whether LLMs can provide treatment ...
