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.'

Flesh-eating bacteria have caused several deaths in Florida and Louisiana this summer. How to reduce your risk of Vibrio vulnificus infection before swimming in the ocean.
Infections are rare, but a person can get sick by swimming in the ocean with an open wound or by eating contaminated raw shellfish. Health officials in several states are alerting residents about a flesh-eating bacteria that thrives in warm coastal waters. Approximately 60 cases of Vibrio vulnificus have been confirmed in 11 states, according to Today. The highest numbers have been in Louisiana (17 cases, including 4 deaths) and Florida (16 cases, including 5 deaths). North Carolina has also seen 7 cases, Yahoo News confirmed with the state's Department of Health and Human Services via email. Vibrio vulnificus cases are considered rare, with between 150 and 200 infections reported in the U.S. each year, according to the Cleveland Clinic. However, many people with an infection can become seriously ill, requiring intensive care or limb amputation. 'About 1 in 5 people with this infection die, sometimes within a day or two of becoming ill,' according to the Centers for Disease Control and Prevention. Does this mean you should avoid the ocean altogether? Here's what to know and what safety measures to keep in mind: What is Vibrio vulnificus? Vibrio are a type of bacteria that thrive in warm coastal waters during the summer months from May to October. This includes salt water and brackish water, which is a mixture of salt and freshwater often found where rivers meet the ocean. The bacteria are found particularly along the Gulf Coast states like Florida, Louisiana, Texas, Alabama and Mississippi. There are different kinds of Vibrio that can lead to various infections. Vibrio vulnificus can be particularly dangerous because it can cause severe and life-threatening infections. This specific type of bacteria is known as 'flesh-eating' because it can destroy muscle tissue and skin. 'Many people with [Vibrio] vulnificus wound infection require intensive care or surgical tissue removal,' the CDC says. How do people get infected? There are two ways that people can get infected: When a person's open wound is exposed to ocean water or seafood contaminated with Vibrio bacteria. A small cut, scrape or wound from a recent surgery, piercing or tattoo can allow bacteria in. This can happen when a person goes swimming or fishing or prepares raw seafood. When someone eats raw or undercooked seafood or ingests contaminated water while swimming. Oysters, in particular, can concentrate the Vibrio bacteria inside them. What are the symptoms of a Vibrio infection? These are the common signs and symptoms of a Vibrio infection, according to the CDC: Watery diarrhea Stomach cramps Nausea and vomiting Fever/chills Signs of a Vibrio bloodstream infection: Fever/chills Dangerously low blood pressure Blistering skin lesions Signs of a Vibrio wound infection: Fever Pain, redness, swelling, warmth at the wound site Redness Pain Swelling Warmth Discoloration (turning a color other than normal) Discharge (leaking fluids) The Cleveland Clinic and the CDC advise people to go to the emergency room immediately if there are signs of a suspected Vibrio vulnificus infection. Are some people more at risk of an infection? Anyone can become infected with the bacteria through a wound. People with underlying health conditions like liver disease, diabetes and immunocompromising conditions are at higher risk for wound infection, according to the CDC. How can people stay safe? Florida's Health Department and the CDC provide some tips to prevent Vibrio vulnificus infections: Don't eat raw oysters and other raw shellfish. Instead, cook them thoroughly. Avoid cross contamination with raw seafood and other cooked food or shellfish. If you have an open wound or broken skin, avoid warm salt or brackish water, if possible. Cover your wound with a waterproof bandage if it could come into contact with coastal water, raw seafood or its drippings or juices. Wear protective gloves or clothing when handling raw shellfish. Be vigilant after coastal floods, hurricanes and storm surges. Coastal waters forced into inland areas increase the risk for Vibrio wound infections, particularly for people who are older or who have underlying health conditions.

Trusty K-9 companion suiting up to keep University of Minnesota medical student safe
A dog named Nova is suiting up for a very special purpose: keeping a close eye on her human, University of Minnesota medical student Wesley Flint. "Everyday we come in and I put on her boots and her lab coat and her goggles," Flint said. It's all part of Nova's personal protection equipment (PPE) routine as Flint's trusted assistant. Nova is led to her work space, a plush mat under a nearby table, and patiently waits until she's needed. "She's my medical alert dog. I'm a Type-1 diabetic," Flint said. "Diabetic alert dogs can actually smell the change in your blood sugar before any glucose sensor can pick it up a lot of the time." Sometimes, Nova can sense a blood-sugar drop up to a half hour before Flint's arm sensor does. "When my blood sugar is low, she'll get off the mat and come over to me and head butt me against the thigh," Flint said. "If she gives me an alert, I can check my sensor to see which way I'm trending. She's pretty accurate. Pretty rare for her to be wrong." Is Flint worried about technology or AI replacing Nova some day? "I don't think AI has a nose yet, and I'm not sure we can manufacture a robotic nose sensitive enough," Flint said.
