The number of confirmed U.S. coronavirus cases passed 2 million on Thursday, as public health experts warned of the emergence of new COVID-19 hotspots across the country. Just three weeks after Arizona Gov. Doug Ducey lifted the state’s stay-at-home order, there has been a significant spike in coronavirus cases, with lawmakers and medical professionals warning that hospitals might not be able to handle a big influx of new cases. Already, hospitals in the state are at 83 percent capacity, the Associated Press reported. But Arizona is not alone in seeing increases in hospitalizations: new U.S. data shows at least eight other states with spikes since Memorial Day. In Texas, North and South Carolina, California, Oregon, Arkansas, Mississippi and Utah, increasing numbers of COVID-19 patients are showing up at hospitals, the Washington Post reported Wednesday. For example, Texas has reported two consecutive days of record-breaking coronavirus hospitalizations. That state, which was one of the first to reopen, has seen a 36 percent increase in new cases since the end of May, with a record 2,056 hospitalizations recorded by Tuesday afternoon, the Post reported. The hospitalization data challenges the notion that the country is seeing a spike in new coronavirus cases solely because of increased testing, the Post reported. By Thursday, the U.S. coronavirus death toll passed 113,000. On Tuesday, another Post analysis showed that parts of… read on >
A little about: Weekly Gravy
All Sauce from Weekly Gravy:
Leonardo’s ‘Vitruvian Man’ Ideal Isn’t Far Off Modern Measures
More than five centuries ago, Renaissance master Leonardo da Vinci produced a now-famous image of what he considered the perfectly proportioned male body: the “Vitruvian Man.” The drawing was inspired by even earlier pondering on the perfect human form by first-century A.D. Roman architect Vitruvius. Now, work done by American scientists involving high-tech scans of the bodies of almost 64,000 fit young men (and some women), finds that Leonardo got very close to anatomical measurements collected today. “Despite the different samples and methods of calculation, Leonardo da Vinci’s ideal human body and the proportions obtained with contemporary measurements were similar,” reported a team led by Diana Thomas, a mathematician at the U.S. Military Academy in West Point, N.Y. “Vitruvian Man” is an iconic drawing by Leonardo from 1490 in which an adult male stands, legs together and then apart, inside a circle and square whose borders end at his head, outstretched hands and feet. It’s meant to depict the ideal adult male body. But how close did Leonardo get to reality? To find out, Thomas and her colleagues had thousands of highly fit U.S. Air Force training recruits, ages 17 to 21, undergo high-tech 3D body scanning to determine average measurements. For good measure, a separate sample of almost 1,400 female recruits were also scanned — the artist did not produce a “Vitruvian Woman,” however.… read on >
Pandemic Is Changing Your Next Doc Appointment
In response to the coronavirus pandemic, many doctors’ offices and clinics have made changes to protect patients, care providers and staff. As an example, here’s what’s being done at Penn State Health. “When our patients first call to schedule an appointment at any of our offices, outpatient clinics or centers, they’ll be screened for COVID-19,” said Dr. Matthew Silvis. He’s vice chair of clinical operations in the family and community medicine department at the Hershey Medical Center in Hershey, Penn. “This means being asked questions about their possible risk factors of having the coronavirus,” and possibly being asked for additional information over the phone to reduce the amount of paperwork needed at the time of the visit, Silvis said in a health system news release. When patients arrive for their appointment, they will undergo further screening for COVID-19. They’ll be asked about possible exposure, any symptoms and they’ll have their temperature taken. Patients will be required to wear masks that cover their nose and mouth before they can enter the facility. Doctors, nurses and office staff are screened daily for COVID-19 and wear face masks. Some may wear face shields for additional protection. Other changes involve check-in, visitors, waiting areas and check-out. Dr. William Bird, a senior vice president in Penn State Health Medical Group, said, “We’ve eliminated a lot of chairs in the reception… read on >
HealthDay In-DepthThe AI Revolution: For Patients, Promise and Challenges Ahead
Streaks of color swirl through a pulsing, black-and-white image of a patient’s heart. They represent blood, and they’re color-coded based on speed: turquoise and green for the fastest flow, yellow and red for the slowest. This real-time video, which can be rotated and viewed from any angle, allows doctors to spot problems like a leaky heart valve or a failing surgical repair with unprecedented speed. And artificial intelligence (AI) imaging technology made it possible. “It’s quite simple, it’s like a video game,” said Dr. Albert Hsiao, an associate professor of radiology at the University of California, San Diego, who developed the technology while a medical resident at Stanford University. There’s a lot going on behind the scenes to support this simplicity. Each 10-minute scan produces 2 to 10 gigabytes of data. To handle such huge, complicated data sets, Hsiao and his colleagues at Arterys, the company he helped found in 2012 to develop the technology, decided to build the infrastructure on the internet, where it can be accessed by servers from other researchers. And now, investigators around the world are using this cloud-based infrastructure to share and test medical AI imaging models in the Arterys Marketplace. “We’ve made it almost as easy to get medical AI online as to upload a YouTube video,” said Arterys product strategy manager Christian Ulstrup. Arterys decided to open up… read on >
Nine U.S. States Seeing Spikes in COVID-19 Hospitalizations
In another troubling sign that the spread of coronavirus might be accelerating, new U.S. data shows hospitalizations in at least nine states have been on the rise since Memorial Day. In Texas, North and South Carolina, California, Oregon, Arkansas, Mississippi, Utah and Arizona, increasing numbers of COVID-19 patients are showing up at hospitals, the Washington Post reported Wednesday. For example, Texas has reported two consecutive days of record-breaking coronavirus hospitalizations. The state, which was one of the first to reopen, has seen a 36 percent increase in new cases since the end of May, with a record 2,056 hospitalizations recorded by Tuesday afternoon, the Post reported. The hospitalization data challenges the notion that the country is seeing a spike in new coronavirus cases solely because of increased testing, the Post reported. By Wednesday, the U.S. coronavirus case count neared 2 million as the death toll passed 112,000. On Tuesday, another Post analysis showed that parts of the country that had been spared the worst of the coronavirus pandemic are now tallying record-high cases of new infections. Since the start of June, 14 states and Puerto Rico have recorded their highest seven-day average of new coronavirus cases since the pandemic began, data tracked by the Post shows. Those states are Alaska, Arizona, Arkansas, California, Florida, Kentucky, New Mexico, North Carolina, Mississippi, Oregon, South Carolina, Tennessee, Texas… read on >
Latest in Cancer Prevention: Move More, Ditch Beer and Bacon
The latest cancer prevention guidelines may change your typical backyard barbecue: Gone are the hot dogs and booze. In are veggie kebobs and maybe a swim or some badminton. The American Cancer Society’s new cancer prevention recommendations suggest, among other things, adding more physical activity to your days. About 20 minutes a day is the minimum, but 40 minutes or more daily is even better. The new guidelines also add emphasis on avoiding unhealthy foods, including red and processed meats, refined grains and alcohol. “The new recommendations really increase emphasis on a few key areas [including healthy weight and diet, physical activity, and avoiding or limiting alcohol],” said Dr. Laura Makaroff, senior vice president of prevention and early detection for the American Cancer Society (ACS). These factors accounted for up to 18% of cancer cases and 16% of cancer deaths in the United States, according to the new report. Along with recommendations for individual lifestyle practices, the ACS also included guidance for communities to take action. “In addition to recommendations for individual choices, ACS recognizes that making healthy choices can be challenging for many people. We need to reduce barriers to living well and achieving a healthy lifestyle, and that will require working collaboratively at all levels to develop and implement policies to ensure access to healthy foods and opportunities for exercise,” Makaroff said.

HealthDay In-DepthThe AI Revolution: Robots Already Helping Humans Deliver Better Care
Bright yellow and looking like a headless deer, Spot can travel across ground too risky for humans. “Built for dirt and danger,” in the words of its maker Boston Dynamics, this robot is now helping humans battle a different threat: the spread of coronavirus. Equipped with an iPad and two-way radio, Spot has been making the rounds at Brigham and Women’s Hospital in Boston since April. Medical technicians use the robot to interview patients with suspected COVID-19 remotely, with no need to don personal protective equipment. Think of it as mobile telemedicine. Then there’s computer programs that pore through mountains of information to pluck out and analyze the relevant bits to help find a promising drug for COVID-19 after just two days’ work. Artificial intelligence (AI) tools are tackling the pandemic on every front: Robots that blast surfaces with high-power ultraviolet light are decontaminating hospitals around the world. Robots also stepped in to help Chinese hospitals cope with coronavirus, checking visitors’ temperatures, delivering food and medicine, keeping isolated wards clean and even offering a little entertainment. Medical robots can go where human doctors can’t, and process information much faster. But scientists are still only in the very early stages of using AI to treat patients. “There’s still a big gap between this kind of research and the clinical applications,” said Steve Jiang, a professor at… read on >
Record-High Numbers of New COVID-19 Cases Seen in 14 States, Puerto Rico
A new analysis shows that parts of the country that had been spared the worst of the coronavirus pandemic are now tallying record-high cases of new infections. Since the start of June, 14 states and Puerto Rico have recorded their highest seven-day average of new coronavirus cases since the pandemic began, data tracked by the Washington Post shows: Alaska, Arizona, Arkansas, California, Florida, Kentucky, New Mexico, North Carolina, Mississippi, Oregon, South Carolina, Tennessee, Texas and Utah. At the same time, new predictions from the University of Washington in Seattle show the U.S. coronavirus death toll could now hit 145,000 by August, NBC News reported Tuesday. If the prediction bears out, it would mean 30,000 more deaths would occur in the country in the next two months. As of Tuesday, nearly 111,000 COVID-19 deaths have been reported in this country. And in a confusing twist on the effort to understand how coronavirus spreads, a World Health Organization official said Monday that asymptomatic transmission of COVID-19 seems to be rare. Until now, experts believed that transmission by infected people who did not show any symptoms was a main driver of viral spread. “From the data we have, it still seems to be rare that an asymptomatic person actually transmits onward to a secondary individual,” Maria Van Kerkhove, the WHO’s technical lead for coronavirus response and head of… read on >
Fewer Suicide-Related ER Visits in COVID Era, and That Has Experts Worried
The COVID-19 pandemic has had far-reaching effects, and a new study points to yet another: It may be keeping people from seeking emergency care for suicidal thoughts. The study, at one large Ohio health system, found that ER visits for suicidal ideation dropped by over 60% in the month after the state instituted its stay-at-home order. And that’s concerning, researchers said, because, if anything, this is a time when mental health needs are expected to be more acute than ever. “The question is: Where are these patients now?” said senior researcher Dr. Baruch Fertel of the Cleveland Clinic in Ohio. “Are they just brushing off their problems? Are they getting help through telemedicine instead?” Or, most worrisome, are some people going through with suicide instead of getting help? There is no way of knowing at this point, Fertel said, because figures are not available. “Unfortunately, we’ll only find out later, when we’re able to study suicide rates,” he said. The findings, published June 1 in the American Journal of Emergency Medicine, are the latest snapshot of how the COVID-19 pandemic has affected all aspects of medical care. U.S. studies have charted declines in everything from hospital admissions for heart attack, to organ transplants, to childhood vaccinations. In areas hard-hit by the disease, health systems were flooded, and non-urgent medical procedures put on hold. But even… read on >
HealthDay In-DepthThe AI Revolution: Giving Docs a Diagnostic Assist
Back before coronavirus took over the headlines, every week seemed to bring another report about artificial intelligence besting human doctors at everything from diagnosing skin cancer to spotting pneumonia on chest X-rays. But these artificial intelligence (AI) tools — computer programs that get better at performing a task by being “trained” on the right kind of data — are years away from being used to help diagnose real-life patients, according to the doctors helping to develop and test them. “We still have a lot of unknowns in terms of generalizing and validation of these systems before we can start using them as standard of care,” said Dr. Matthew Hanna, a pathologist at Memorial Sloan Kettering Cancer Center in New York City. Generalizing means building an AI tool that can be used in multiple hospitals, and validation involves testing and adjusting an AI tool to ensure it’s accurate. “These are the types of studies we need to do to make sure these models are performing properly and not potentially harming patients,” Hanna explained. Meanwhile, humans are in no rush to swap their doctor for an AI diagnosis. In a 2019 New York University-Harvard study, business school students said they’d be OK with getting poorer quality health care as long as it was provided by a human instead of AI. People resisted AI, the study authors found,… read on >
