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

WEST PALM BEACH, Fla. — A Florida family is grateful to be alive after they say their refrigerator exploded inside their home Saturday morning. The force was so powerful it caused significant damage in several rooms. Luckily, neighbor Joshua Perez heard the explosion and ran inside to help the family get out safely. “I was in my room, I was asleep and I just heard the bang,” Mark Ligondie said. Ligondie quickly ran from his bedroom to the kitchen where moments before his parents' refrigerator in the West Palm Beach, Florida home exploded. “There were fumes coming everywhere,” Ligondie said. He says the odor was so strong and that it made his eyes sting. “The fridge exploded and if you look at this angle right here it expanded and expanded so much it bent the metal of the stove,” Ligondie said. The family's 4-month-old Whirlpool refrigerator was in pieces, scattered throughout the kitchen and surrounding rooms. Their next door neighbor, Perez, rushed over to help after hearing the loud bang and smoke alarm. "Immediately I just see the smoke,” Perez said. Luckily, no one was hurt. The fire department showed up and cleared the home. “And for them to say we’ve never seen this, this is something we have never seen in our life is kind of alarming,” Perez said. Perez believes this incident is a wake-up call for all homeowners.“I’ve actually scheduled an appointment already because of how nervous this has made me just for general maintenance and I think that’s something everyone should do,“ Perez said. WPTV reached out to Whirlpool for comment. We are still waiting to hear back. Meanwhile, there's now cracks in the family's ceiling and nearby walls, damage to the master bedroom door and a bedroom window is missing. "It's surreal," Ligondie said. 1780

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
