Study shows how AI can improve physicians diagnostic accuracy

first_imgTen ophthalmologists (four general ophthalmologists, one trained outside the US, four retina specialists, and one retina specialist in training) were asked to read each image once under one of three conditions: unassisted, grades only, and grades + heatmap.Both types of assistance improved physicians’ diagnostic accuracy. It also improved their confidence in the diagnosis. But the degree of improvement depended on the physician’s level of expertise.Without assistance, general ophthalmologists are significantly less accurate than the algorithm, while retina specialists are not significantly more accurate than the algorithm. With assistance, general ophthalmologists match but do not exceed the model’s accuracy, while retina specialists start to exceed the model’s performance.”What we found is that AI can do more than simply automate eye screening, it can assist physicians in more accurately diagnosing diabetic retinopathy,” said lead researcher, Rory Sayres, PhD.. “AI and physicians working together can be more accurate than either alone.”Like medical technologies that preceded it, Sayres said that AI is another tool that will make the knowledge, skill, and judgment of physicians even more central to quality care.”There’s an analogy in driving,” Sayres explained. “There are self-driving vehicles, and there are tools to help drivers, like Android Auto. The first is automation, the second is augmentation. The findings of our study indicate that there may be space for augmentation in classifying medical images like retinal fundus images. When the combination of clinician and assistant outperforms either alone, this provides an argument for up-leveling clinicians with intelligent tools.” Source:https://www.aao.org/newsroom/news-releases/detail/how-ai-can-make-ophthalmologists-more-effective Reviewed by James Ives, M.Psych. (Editor)Mar 19 2019As artificial intelligence continues to evolve, diagnosing disease faster and potentially with greater accuracy than physicians, some have suggested that technology may soon replace tasks that physicians currently perform. But a new study from the Google AI research group shows that physicians and algorithms working together are more effective than either alone. It’s one of the first studies to examine how AI can improve physicians’ diagnostic accuracy. The new research will be published in the April edition of Ophthalmology, the journal of the American Academy of Ophthalmology.This study expands on previous work from Google AI showing that its algorithm works roughly as well as human experts in screening patients for a common diabetic eye disease called diabetic retinopathy. For their latest study, the researchers wanted to see if their algorithm could do more than simply diagnose disease. They wanted to create a new computer-assisted system that could “explain” the algorithm’s diagnosis. They found that this system not only improved the ophthalmologists’ diagnostic accuracy, but it also improved algorithm’s accuracy.More than 29 million Americans have diabetes, and are at risk for diabetic retinopathy, a potentially blinding eye disease. People typically don’t notice changes in their vision in the disease’s early stages. But as it progresses, diabetic retinopathy usually causes vision loss that in many cases cannot be reversed. That’s why it’s so important that people with diabetes have yearly screenings.Unfortunately, the accuracy of screenings can vary significantly. One study found a 49 percent error rate among internists, diabetologists, and medical residents.Recent advances in AI promise to improve access to diabetic retinopathy screening and to improve its accuracy. But it’s less clear how AI will work in the physician’s office or other clinical settings. Previous attempts to use computer-assisted diagnosis shows that some screeners rely on the machine too much, which leads to repeating the machine’s errors, or under-rely on it and ignore accurate predictions. Researchers at Google AI believe some of these pitfalls may be avoided if the computer can “explain” its predictions.Related StoriesAXT enhances cellular research product portfolio with solutions from StemBioSysScientists develop universal FACS-based approach to heterogenous cell sorting, propelling organoid researchAMSBIO offers new, best-in-class CAR-T cell range for research and immunotherapyTo test this theory, the researchers developed two types of assistance to help physicians read the algorithm’s predictions.center_img Grades: A set of five scores that represent the strength of evidence for the algorithm’s prediction.

Barry Becomes a Hurricane Barrels Toward Louisiana Coast

first_imgHurricane Barry is barreling northwest toward Louisiana, packing maximum sustained winds of 75 mph (120 km/h), with heavy rain, storm surges and dangerous winds expected along the northwest Gulf Coast. As of 11 a.m. ET, Barry was moving northwest in the Gulf of Mexico at 6 mph (9 km/h), and its eye was about 40 miles (65 kilometers) south of Lafayette, Louisiana, and about 50 miles (80 km) west of Morgan City, Louisiana. Hurricane forecasters expect the hurricane to lose strength over the next few hours, getting downgraded back to a tropical storm. The National Oceanic and Atmospheric Administration (NOAA) has issued a hurricane warning from Louisiana’s Intracoastal City to Grand Isle, meaning hurricane conditions are expected somewhere in that area over the next 36 hours or so.Headbutting Tiny Worms Are Really, Really LoudThis rapid strike produces a loud ‘pop’ comparable to those made by snapping shrimps, one of the most intense biological sounds measured at sea.Your Recommended PlaylistVolume 0%Press shift question mark to access a list of keyboard shortcutsKeyboard Shortcutsplay/pauseincrease volumedecrease volumeseek forwardsseek backwardstoggle captionstoggle fullscreenmute/unmuteseek to %SPACE↑↓→←cfm0-9接下来播放Why Is It ‘Snowing’ Salt in the Dead Sea?01:53 facebook twitter 发邮件 reddit 链接https://www.livescience.com/65932-hurricane-barry-barrels-toward-louisiana.html?jwsource=cl已复制直播00:0000:3500:35  Barry is expected to turn toward the north-northwest tonight, followed by a turn toward the north on Sunday (July 14), NOAA said. The center of the storm is forecast to move through southern Louisiana today and central Louisiana tonight. Then on Sunday, it should be churning through northern Louisiana, NOAA forecasts. “A lot of rainfall still yet to come out in the Gulf of Mexico,” NOAA National Hurricane Center director Ken Graham said during a Facebook Live at 11 a.m. ET. The rainfall will then start to impact portions of Louisiana, including New Orleans, he said. Because of the high winds, there’s a chance of tornadoes spinning off Barry. “A few tornadoes are possible through tonight across the southeast Louisiana, southern Mississippi and southern Alabama,” according to NOAA’s forecast.

Not a smooth road ahead for Kartarpur corridor amid IndiaPak differences over

first_img Next Not a smooth road ahead for Kartarpur corridor amid India-Pak differences over constructionWhile India is making a bridge for the pilgrims, the Pakistani side is constructing a “causeway”, which has been a persistent bone of contention between India and Pakistan on the Kartarpur corridor issue. advertisement Kamaljit Kaur Sandhu New DelhiJuly 12, 2019UPDATED: July 12, 2019 17:51 IST Sources have said that the Kartarpur corridor structure on the Indian side will be completed by October 31. (India Today file photo)The Indian and the Pakistani officials will meet this Sunday for the second high-level talks on the Kartarpur Sahib corridor. The meeting is to find a way to iron out disagreements between the two countries. The Indian side is likely to reiterate the same set of concerns as the key issue remains unresolved — the construction of a causeway by Pakistan.While India is making a bridge for the pilgrims, the Pakistani side is constructing a “causeway”, which has been a persistent bone of contention between India and Pakistan on the Kartarpur corridor issue.India is of the view that not building a bridge would lead to flooding of the Indian areas during monsoon when the Ravi river overflows.”India has disagreed on the construction of a causeway. Causeways are not considered good engineering. India has been covering the Indian side of 68 km bund while the Pakistani side has a vast 250 km bund. Flooding in monsoon is a concern,” a government source said.The Indian team has suggested the use of “service road” by pilgrims till the time the bridge is not built by Pakistan.Kartarpur corridor structure on Indian side to be completed by October 31: SourcesA day after the Ministry of Home Affairs (MHA) sought to dismiss “misconceptions” that India has been slow in completing its side of the Kartarpur corridor, government sources have claimed that the construction on the Indian will be completed by October 31.The sources also said that the Indian government expects completion of the Kartarpur corridor on both the sides before the 550th birth anniversary of Guru Nanak Dev. Speaking to news agency ANI, a government source said, “Construction of the Kartarpur corridor on the Indian side will be completed by October 31. Sixty per cent is done. The government is keen that the Kartarpur corridor is completed on both the sides by the 550th anniversary of Guru Nanak Dev ji. India is looking forward to it with high expectation.”The movement of the Kartarpur corridor pilgrims is expected to be discussed in the meeting. Discussions on permits or visa-free access to all the pilgrims, fees and journey time of the pilgrims are also expected during the Kartarpur corridor talks.”India is creating an all-weather facility to cater to 10,000 pilgrims on special occasions and 5,000 pilgrims daily,” the source said, adding, “India will use high tech surveillance system and put a robust security system in place. That is not negotiable.”However, Pakistan wants to limit the number of pilgrims to 750 a day. Sources say that despite three technical meetings, the Pakistani side has not responded positively.Will reiterate concern regarding Khalistani terrorist Gopal Singh Chawla: SourcesThe government sources have said the Indian side will reiterate their concern regarding the Khalistani terrorist, Gopal Singh Chawla. Gopal Singh Chwala is linked to Sikh Gurdwara Parbandhak Committee and works in the capacity of its general secretary.
