Childhood exposure to air pollution, BMI trajectories and insulin resistance among young adults

JAMA Network Open

2025-04-22

(Press-News.org) About The Study: In this cohort study of young adults, the long-term association between traffic-related air pollution and insulin resistance may be partially explained by higher body mass index (BMI) and accelerated BMI growth from early adolescence into young adulthood. These findings highlight the importance of weight management in children, particularly those residing in highly polluted areas.

Astronomers discover a planet that’s rapidly disintegrating, producing a comet-like tail

2025-04-22

MIT astronomers have discovered a planet some 140 light-years from Earth that is rapidly crumbling to pieces. The disintegrating world is about the mass of Mercury, although it circles about 20 times closer to its star than Mercury does to the sun, completing an orbit every 30.5 hours. At such close proximity to its star, the planet is likely covered in magma that is boiling off into space. As the roasting planet whizzes around its star, it is shedding an enormous amount of surface minerals and effectively evaporating away. The astronomers spotted the planet using NASA’s Transiting ...

Study reveals gaps in flu treatment for high-risk adults

2025-04-22

INDIANAPOLIS – A multi-state study reveals that many high-risk adults diagnosed with influenza (flu) in emergency departments and urgent care centers are not receiving timely antiviral treatment. Researchers found that only slightly more than half of these patients received antiviral prescriptions, and of those, only 80 percent were filled. This gap in treatment could increase the risk of severe flu complications, particularly for older adults and those with underlying conditions. The study analyzed prescribing and ...

Oil cleanup agents do not impede natural biodegradation

2025-04-22

Highlights: Biodegradation is an important natural process during oil spill cleanup. A new study revealed that using spill treating agents does not negatively impact naturally occurring biodegradation. Washington, D.C.—Using spill treating agents to clean up oil spills does not significantly hinder naturally occurring oil biodegradation, according to a new study. The study, published in Applied and Environmental Microbiology, a journal of the American Society for Microbiology, provides information that will be useful in future oil ...

AI algorithm can help identify high-risk heart patients to quickly diagnose, expedite, and improve care

2025-04-22

Mount Sinai researchers studying a type of heart disease known as hypertrophic cardiomyopathy (HCM) have calibrated an artificial intelligence (AI) algorithm to quickly and more specifically identify patients with the condition and flag them as high risk for greater attention during doctor’s appointments. The algorithm, known as Viz HCM, had previously been approved by the Food and Drug Administration for the detection of HCM on an electrocardiogram (ECG). The Mount Sinai study, published April 22 in the journal NEJM AI, assigns numeric probabilities to the algorithm’s ...

Telemedicine had an impact on carbon emissions equivalent to reducing up to 130,000 car trips each month in 2023

2025-04-22

Telemedicine use in 2023 reduced monthly carbon dioxide emissions by the equivalent of up to 130,000 gas operated vehicles, suggesting it could have a positive effect on climate change, new UCLA-led research finds. The findings, to be published April 22 in the peer-reviewed American Journal of Managed Care, suggest that telemedicine could have a modest but noticeable impact on the environment by decreasing the number of vehicles traveling to and from medical appointments. They could also have policy implications, said co-senior author Dr. John N. Mafi, associate professor-in-residence of medicine in the division of general internal medicine and health services research ...

Three-dimensional gene hubs may promote brain cancer

2025-04-22

The way DNA folds inside the nucleus of brain cells may hold the key to understanding a devastating form of brain cancer called glioblastoma, suggests a new preclinical study from Weill Cornell Medicine researchers. The findings, published April 3 in Molecular Cell, offer a new way to think about cancer beyond gene mutations, based on the way that genes are connected and regulated in three-dimensional space. “Glioblastoma is one of the most aggressive and incurable tumors. Although we know a lot about the mutations and the genes that characterize it, we still have no effective ways to stop it,” said Dr. Effie ...

Liquid biopsy: A breakthrough technology in early cancer screening

2025-04-22

Cancer is one of the leading causes of death globally, with nearly 20 million new cases and 9.7 million deaths in 2022. Early detection plays a crucial role in reducing cancer-related morbidity and mortality, but many cancers are diagnosed at advanced stages due to subtle early symptoms and lack of awareness. Liquid biopsy, a non-invasive approach that examines circulating tumor components in body fluids, has emerged as a groundbreaking technology in cancer detection. This review presents the advancements in liquid ...
