"Flesh-eating" bacteria risk increasing as ocean temperatures rise
Lifelong boat captain George Billiris says he's lucky to be alive after Vibrio vulnificus, the so-called "flesh-eating" bacteria that lurks in warm coastal waters like those along Florida's Gulf Coast, nearly killed him. "I started to get chills, feverish, my leg was swelling, burning," the third-generation sponge fisherman told CBS News. Billiris was wading in the water while fishing with his grandson back in July 2019 when he contracted the bacteria, which got into his system through a cut he had on his back leg. It was "just a little tiny scab," Billiris said. At the hospital, doctors used a marker on his leg to track the spread of the bacteria. After three weeks of treatment, the infection subsided, saving his leg from amputation. According to the Centers for Disease Control and Prevention, one in five people who contract the bacteria die after rapid spread of the infection. During hurricane season, the danger of contracting Vibrio vulnificus heightens, according to Dr. Valerie Harwood, a microbiologist at the University of South Florida. Research also shows the ocean's water temperature is rising due to climate change, which leads to more frequent and severe storms. Harwood said that because the bacteria thrives in warmer waters, it means more infections are seen in places that haven't experienced them before as water temperatures rise in those regions. "With warming waters, we are seeing cases further north," Harwood said. In recent years, cases have been reported in the Carolinas, and even as far north as Connecticut and New York. This year, there have been 17 cases in Louisiana, 16 in Florida and seven in North Carolina. Florida has reported five deaths so far, the most of any state. The bacteria can also spread through uncooked seafood, mainly oysters. These days, Billiris says he is more cautious in the water, but he still sails his family's boat nearly every day. He hopes others will recognize the symptoms of an infection, because earlier treatment could mean the difference between life and death. "Lot of people waited because they didn't know," he said.

Using AI tools can ‘deskill' certain health workers
Using AI regularly can potentially 'deskill' health workers, a new study suggests. Academics said that the finding is 'concerning' given the rapid uptake of artificial intelligence (AI) across healthcare. The new study looked at health workers who perform a test to look for early signs of bowel cancer. Endoscopists perform a test called a colonoscopy to look for precancerous growths in the bowel known as adenomas. This means these pre-cancerous growths can be detected and removed, preventing them from becoming bowel cancer. Advances in AI technology have led to the development of computer-assisted polyp detection systems, which have been found to help these health workers spot more adenomas. Researchers wanted to assess whether continuous use of AI led to a dip in performance when endoscopist perform colonoscopies without AI by analysing work conducted in Poland. The research team analysed 1,442 colonoscopies conducted by experienced health workers before and after AI systems were rolled out at certain centres in 2021. Writing in the journal Lancet Gastroenterology and Hepatology, researchers reported that the rate of detection of polyps was 6% lower after the introduction of AI in standard and non-AI assisted colonoscopies. 'To our knowledge this is the first study to suggest a negative impact of regular AI use on healthcare professionals' ability to complete a patient-relevant task in medicine of any kind,' said one of the study authors, Dr Marcin Romanczyk, Academy of Silesia in Poland. 'Our results are concerning given the adoption of AI in medicine is rapidly spreading. 'We urgently need more research into the impact of AI on health professional's skills across different medical fields. We need to find out which factors may cause or contribute to problems when healthcare professionals and AI systems don't work well together, and to develop ways to fix or improve these interactions.' In a linked editorial, Omer Ahmad, a consultant gastroenterologist and interventional endoscopist and clinical research fellow at University College London, wrote: 'These findings temper the current enthusiasm for rapid adoption of AI-based technologies such as CADe and highlight the importance of carefully considering possible unintended clinical consequences. 'The study provides the first real-world clinical evidence for the phenomenon of deskilling, potentially affecting patient-related outcomes.' Sign in to access your portfolio

Mentally Ill Detainees Are Trapped in Legal Limbo, Lawsuit Says
Hundreds of mentally ill detainees who were found unfit to stand trial are languishing in New York City's jails because the state has been too slow in moving them through its byzantine treatment system, a public defender organization said in a lawsuit filed Tuesday. Under New York State law, people who are too mentally ill to understand the charges against them and aid in their own defense are supposed to be restored to competency in a hospital operated by the state Office of Mental Health before their legal proceedings can continue. But bed and staffing shortages at the hospitals have led to long delays in people receiving the care, leaving them to linger amid disorder and dangerous conditions on Rikers Island, the suit said. A class action, it was filed by the Legal Aid Society and a New York University law clinic in Federal District Court in Manhattan. More than half the people in city custody are mentally ill, records show, and on any given day about 100 people are held on Rikers Island while awaiting transfer to be restored to competency, the suit said. The average wait time for a bed is about two and a half months, the suit said. Some wait longer: In 2024, 130 people spent more than 100 days on waiting lists for the treatment. In some cases, the long delays have proved fatal. At least five people who have died after being held on Rikers Island since 2021 had been ordered to be restored to competency, the suit said.
