We heard a lot about flattening the curve during the beginning of the pandemic. It had to do with making sure hospitals didn't get overwhelmed with patients sick from the virus.Stay-at-home orders and canceling elective medical procedures were necessary. Now, there's a second curve researchers are concerned about flattening. It has to do with what's expected to be a rush on the health care system when all those procedures that were put on hold get rescheduled.Researchers at Johns Hopkins University are studying what's happening in real-time. They are also able to point to some past events that might give them an idea of what could happen.In the case of Ebola, patients didn't come back in for elective surgeries and treatments right away.“You started from very low but then very, very quickly that rebounded at a very surprisingly fast pace,” said Tinglong Dai, a professor at Johns Hopkins Carey Business School.So, as more states restart elective procedures, the curve and demand on the health care system will go up and researchers suggest if not prepared, it could catch them off guard.Plus, with concerns about a second wave of the coronavirus, there's potential to reach capacity.“On the supply side, you could have nurses getting sick, doctors getting sick and in fact you may not have enough testing because even now we don’t have enough testing,” said Dai.The research is looking at what's happening right now in Johns Hopkins dermatology with nearly all skin cancer treatments on hold.They hope to come up with the best models to flatten the curve on elective procedures to help reduce the negative implications on patient outcomes and added costs. They hope to have the papers ready by January. 1725

Why would the #USWNT deserve equal pay with men when they can be beaten by an under 15s boys team?Pay on ability, reward on performance, promote on merit. 15 year old boys are more able than this team Facts don’t care about your feelings. pic.twitter.com/iY4jziil1Z— Katie Hopkins (@KTHopkins) July 8, 2019 318

Wisconsin Gov. Tony Evers ordered the state's 112 troops to leave their posts along the US' southern border Monday evening.The Democrat's order makes Wisconsin the third state to pull National Guard personnel from the border this month, citing President Donald Trump's rhetoric around border security."There is simply not ample evidence to support the president's contention that there exists a national security crisis at our Southwestern border," Evers said 472

Two centuries after its invention, the stethoscope — the very symbol of the medical profession — is facing an uncertain prognosis.It is threatened by hand-held devices that are also pressed against the chest but rely on ultrasound technology, artificial intelligence and smartphone apps instead of doctors’ ears to help detect leaks, murmurs, abnormal rhythms and other problems in the heart, lungs and elsewhere. Some of these instruments can yield images of the beating heart or create electrocardiogram graphs.Dr. Eric Topol, a world-renowned cardiologist, considers the stethoscope obsolete, nothing more than a pair of “rubber tubes.”It “was OK for 200 years,” Topol said. But “we need to go beyond that. We can do better.”In a longstanding tradition, nearly every U.S. medical school presents incoming students with a white coat and stethoscope to launch their careers. It’s more than symbolic — stethoscope skills are still taught, and proficiency is required for doctors to get their licenses.Over the last decade, though, the tech industry has downsized ultrasound scanners into devices resembling TV remotes. It has also created digital stethoscopes that can be paired with smartphones to create moving pictures and readouts.Proponents say these devices are nearly as easy to use as stethoscopes and allow doctors to watch the body in motion and actually see things such as leaky valves. “There’s no reason you would listen to sounds when you can see everything,” Topol said.At many medical schools, it’s the newer devices that really get students’ hearts pumping.“Wow!” ″Whoa!” ″This is awesome,” Indiana University medical students exclaimed in a recent class as they learned how to use a hand-held ultrasound device on a classmate, watching images of his lub-dubbing heart on a tablet screen.The Butterfly iQ device, made by based by Guilford, Connecticut-based Butterfly Network Inc., went on the market last year. An update will include artificial intelligence to help users position the probe and interpret the images.Students at the Indianapolis-based medical school, one of the nation’s largest, learn stethoscope skills but also get training in hand-held ultrasound in a program launched there last year by Dr. Paul Wallach, an executive associate dean. He created a similar program five years ago at the Medical College of Georgia and predicts that within the next decade, hand-held ultrasound devices will become part of the routine physical exam, just like the reflex hammer.The devices advance “our ability to take peek under the skin into the body,” he said. But Wallach added that, unlike some of his colleagues, he isn’t ready to declare the stethoscope dead. He envisions the next generation of physicians wearing “a stethoscope around the neck and an ultrasound in the pocket.”Modern-day stethoscopes bear little resemblance to the first stethoscope, invented in the early 1800s by Frenchman Rene Laennec, but they work essentially the same way.Laennec’s creation was a hollow tube of wood, almost a foot long, that made it easier to hear heart and lung sounds than pressing an ear against the chest. Rubber tubes, earpieces and the often cold metal attachment that is placed against the chest came later, helping to amplify the sounds.When the stethoscope is pressed against the body, sound waves make the diaphragm — the flat metal disc part of the device — and the bell-shaped underside vibrate. That channels the sound waves up through the tubes to the ears. Conventional stethoscopes typically cost under 0, compared with at least a few thousand dollars for some of the high-tech devices.But picking up and interpreting body sounds is subjective and requires a sensitive ear — and a trained one.With medical advances and competing devices over the past few decades, “the old stethoscope is kind of falling on hard times in terms of rigorous training,” said Dr. James Thomas, a cardiologist at Northwestern Medicine in Chicago. “Some recent studies have shown that graduates in internal medicine and emergency medicine may miss as many of half of murmurs using a stethoscope.”Northwestern is involved in testing new technology created by Eko, a Berkeley, California-based maker of smart stethoscopes. To improve detection of heart murmurs, Eko is developing artificial intelligence algorithms for its devices, using recordings of thousands of heartbeats. The devices produce a screen message telling the doctor whether the heart sounds are normal or if murmurs are present.Dennis Callinan, a retired Chicago city employee with heart disease, is among the study participants. At age 70, he has had plenty of stethoscope exams but said he feels no nostalgia for the devices.“If they can get a better reading using the new technology, great,” Callinan said.Chicago pediatrician Dr. Dave Drelicharz has been in practice for just over a decade and knows the allure of newer devices. But until the price comes down, the old stalwart “is still your best tool,” Drelicharz said. Once you learn to use the stethoscope, he said, it “becomes second nature.”“During my work hours in my office, if I don’t have it around my shoulders,” he said, “it’s as though I was feeling almost naked.” 5223
