Two of America’s largest retailers, Walmart and Kroger, announced this week that the open carry of firearms would no longer be welcomed at their stores in states that permit open carry. The announcements follow a mass shooting at a Walmart in El Paso, Texas, that killed 21 people in August. CVS and Walgreens also joined the list of retailers that request customers to leave their guns at home.At several other retailers, customers have not been allowed to carry weapons, concealed or open, at their locations for years. Target established its policy prohibiting weapons in its stores in 2014. Then CEO John Mulligan said.“Bringing firearms to Target creates an environment that is at odds with the family-friendly shopping and work experience we strive to create.”Costco has a similar policy, stating that its members agree to abide by its membership conditions, which prohibit weapons in stores.“At Costco, we don't believe it's necessary to bring firearms into its warehouses, except in the case of authorized law enforcement officers,” the company says. “For the protection of all our members and employees, we feel this is a reasonable and prudent precaution to ensure a pleasant shopping experience and safe workplace.” But not all retailers have adopted such policies. Home Depot said it permits weapons in its stores.“The Home Depot allows concealed carry and open carry where permissible by local laws,” a Home Depot spokesperson said. Representatives from McDonald's, Kohl's, Lowe's, and and Best Buy have not responded to a request for information. 1573

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

When former Minneapolis police officer Derek Chauvin was arrested on Friday on third-degree murder charges, more details emerged on how George Floyd died while in police custody on Monday. According to a report prepared by prosecutors in Hennepin County, Minnesota, Chauvin knelt on Floyd’s neck for eight minutes, 46 seconds. For the final two minutes and 53 seconds, prosecutors said, Floyd was unresponsive. Police body cams showed that at 8:24:24, Floyd stopped moving. At 8:25:31, video showed that Floyd stopped talking and breathing. It was not until 8:27:24 when video showed that Chauvin removed his knee from Floyd’s neck, prosecutors said. The prosecution’s report said that “police are trained that this type of restraint with a subject in a prone position is inherently dangerous.”After Chauvin lifted his knee, Floyd was placed on a gurney and taken to the hospital, where he pronounced dead. The county medical examiner reported to prosecutors that several factors likely contributed to Floyd’s death. “The autopsy revealed no physical findings that support a diagnosis of traumatic asphyxia or strangulation,” the report read. "Mr. Floyd had underlying health conditions including coronary artery disease and hypertensive heart disease. The combined effects of Mr. Floyd being restrained by the police, his underlying health conditions and any potential intoxicants in his system likely contributed to his death.”To read the full arrest report, click 1479

WASHINGTON, D.C. – President Donald Trump announced several new actions on Wednesday that his administration is taking to combat the ongoing coronavirus crisis. One of the big updates that Trump announced during his White House press briefing was that the Department of Housing and Urban Development (HUD) will be suspending all foreclosures and evictions until the end of April. HUD's move is meant to bring relief to renters and homeowners who will lose income as the country practices social distancing due to the COVID-19 outbreak.Trump also said that he is invoking the Defense Production Act to expand the U.S. response to the outbreak. The federal provision, “confers upon the president a broad set of authorities to influence domestic industry in the interest of national defense,” according to the 819

Whether on the field or from the sidelines, it’s clear to see rugby is a very special sport. A sport where every athlete runs, rucks, scrums, and mauls. Oh yeah, they also tackle without any pads. “There’s a lot more adrenaline going, and a lot of times, I won’t even realize that I’ve been stepped on,” says rugby player Kaya Troyer. “Which is a little different than other sports.”Now, this sport played around the world is attracting more athletes in the United States. Players like Abigail Tofoya, who traveled from to California to Colorado for a girls rugby camp.“It’s a sisterhood; it’s a bond,” she says. “You develop so many friendships through this.”In 2014, the Sports and Fitness Industry Association reported rugby as the fastest growing team sport in the U.S., with participation growing by 350 percent in a five-year period.“Rugby, it gives me that very competitive edge,” says rugby player Lena Luciano.To gain that competitive edge, players are learning from the best rugby minds the country has to offer. Getting top-level tips from coaches like Jaime Burke, who represented her country while playing for the U.S. Women’s National Team in three Women’s Rugby World Cups.“It’s much different than when I first started out,” she says. “At this point, we have pretty much year-round programming from U8 all the way through U15.”Attracting a bigger audience, however, doesn’t come without concern.“Her daughter wanted my daughter to play and I was like, ‘No way! You’re crazy!’” recalls rugby parent Robin Hartman.Injuries do happen in all sports, including rugby.“The biggest risks we’re seeing is when we look at elite players, collegiate players, and youth players is a risk to the head and neck and then ligament injuries are also pretty common as well,” explains Scott Laker, MD, medical director of the UCHealth Concussion Clinic.Dr. Laker broke down the health risks ranked by sport.“Youth hockey probably has the highest rate of concussions, then probably youth rugby, and then below that is youth soccer,” he says. “The lowest rate is swimming and diving.” Some athletes, however, enjoy contact and say that the excitement of rugby continues to grow among girls across the country one game at a time. 2236
