Carriers of colibactin-producing E. coli face threefold increase in colorectal cancer risk

Researchers from Kyoto Prefectural University of Medicine and collaborating Japanese institutions found that patients carrying colibactin-producing Escherichia coli (pks+ E. coli) in their colon polyps were more than three times as likely to have a history of colorectal cancer compared to those without the bacterium.

AI voice test could help spot dangerous throat lesions before symptoms appear

Researchers at Oregon Health and Science University found that variability in the harmonic-to-noise ratio (HNR) of speech could help distinguish benign from malignant vocal fold lesions, offering a potential early detection biomarker. The exploratory study used AI to analyze acoustic features from the Bridge2AI-Voice dataset and found differences most pronounced in male participants.

AI use in colonoscopy may weaken doctors' detection skills over time

The introduction of artificial intelligence (AI) to assist colonoscopies is linked to a reduction in the ability of endoscopists (health professionals who perform colonoscopies) to detect precancerous growths (adenomas) in the colon without AI assistance, according to a paper published in The Lancet Gastroenterology & Hepatology journal.
