The system--CheXpert--was developed using 188,000 chest images by researchers at Stanford University and fine-tuned by a team at Intermountain Medical Center to identify suspected pneumonia. If implemented in an emergency department, physicians may be able to treat patients sooner--vital to those suffering from pneumonia.
With those limitations in mind, the Johns Hopkins team set out to reimagine the stethoscope. They designed a device capable of capturing the sound of the lungs while filtering out outside noise, and then they created an AI-powered app that "listens" to the lung sound for signs of pneumonia. According to a blog post written by the researchers, the app was 87 percent accurate at distinguishing between the lung sounds of people with pneumonia and healthy people, "far surpassing other automatic diagnosis methods." The Johns Hopkins team is currently field testing prototypes of its smart stethoscope in Peru, Bangladesh, Malawi, and the U.S., and it has high hopes for the future of the final version of the device, which it expects to be "significantly cheaper" than the $500 electronic stethoscopes currently on the market. "By enabling on-the-spot screenings with a cheap device that can be handled by local health workers, we hope our reengineered scope will make a difference in the global health crisis of childhood pneumonia," the researchers wrote.
Tokyo stocks tumbled Monday, battered by mounting concerns over a further spread of pneumonia caused by a new strain of coronavirus from China. The Nikkei 225 average dived 483.67 points, or 2.03 percent, to end at 23,343.51 after briefly losing over 500 points. On Friday, the key market gauge rose 31.74 points. The Topix, which covers all first-section issues on the Tokyo Stock Exchange plunged 27.87 points, or 1.61 percent, to 1,702.57 A wide range of issues came under heavy selling pressure from the outset as investors rushed to reduce risk exposure out of growing fears about the spread of the pneumonia following reports of an increase in the number of infected patients and the death toll, brokers said.
