临沧阴道口摸到有肉疙瘩(临沧40岁不来月经) (今日更新中)

Twitter removing number counts on retweets and likes is an asisine move. Eliminates a lot of the energy that makes this platform go, the meritocracy it is from a content perspective and compromises the ability to pick out the value of what’s important in the moment.— Darren Rovell (@darrenrovell) March 13, 2019 324

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

University of Pittsburgh Medical Center Children's Hospital confirmed on Monday 12 cases of a drug-resistant staph infection in its neonatal intensive care unit (NICU), according to a statement from the hospital.The six babies, including one who is potentially symptomatic, and six symptomatic employees who have tested positive for 345

US rapper A$AP Rocky will find out if he has been found guilty of assault over a street brawl in Stockholm when a Swedish court delivers its judgment on Wednesday.The performer and two members of his entourage were taken into custody on July 3, following a confrontation in the Swedish capital on June 30.Swedish public prosecutor Daniel Suneson told the court the artist and the two other men -- David Rispers and Bladimir Corniel -- assaulted the victim by kicking and beating him with a whole or part of a glass bottle while he lay on the ground.A$AP Rocky, who pleaded not guilty to the charges against him, argued that the trio were simply defending themselves.Known for his song "Praise the Lord," the 30-year-old rapper -- whose real name is Rakim Mayers -- was released by Swedish authorities at the conclusion of the trial on August 2 and left the country shortly afterwards.He is not required to appear in court for Wednesday's ruling.The incident angered fans and fellow artists, and strained diplomatic relations with the United States after President Donald Trump repeatedly demanded the rapper's release, even raising the issue with Swedish Prime Minister Stefan L?fven.In response, L?fven's spokesperson Mikael Lindstr?m said in a statement to CNN at the time that "the Government is not allowed, and will not attempt, to influence the legal proceedings, which are now ongoing."Swedish officials repeatedly stressed that the country's judiciary is "completely independent" and "does not take into consideration outside pressure from politicians or others."The rapper addressed the case during a performance at a music festival in California on Sunday, 1679

Two Stanford University students have filed a lawsuit against eight elite universities claiming they weren't given a fair opportunity to be admitted in the wake of a bribery scandal in which 50 people were arrested.According to 240
