The isolation of the coronavirus pandemic might be stunting the social growth of young children, experts say. Since schools closed across the United States this past spring to stem the spread of COVID-19, kids have been deprived of experiences that are essential to their emotional development — playing at recess, sharing lunch with classmates and learning together in the classroom. In a recent HealthDay Live! interview, Dr. Dimitri Christakis, director of the Center for Child Health, Behavior and Development at Seattle Children’s Research Institute, and Dan Domenech, executive director of The School Superintendents Association, discussed how children might be impacted by the closure of their schools and the disruption of time spent with their peers. Humans are “social animals,” and the limitations placed on social interactions during the pandemic may harm mental health, particularly among children, they said. “We didn’t evolve for this kind of interaction with each other,” Christakis explained. “You can see it in young children. An infant as young as 6 months will attend to another infant. They want to engage with them socially. So, withholding all of that from children is making them pay a price, at least in the short term.” When schools open up, Christakis and Domenech said teachers and administrators should be prepared for a surge of mental health concerns among their students. “We’re working for our teachers…  read on >

Governors across America have eased lockdowns, but a new analysis shows coronavirus cases are rising in nearly half of U.S. states. The rolling seven-day average of new cases per capita has been higher than the average seven days earlier in 21 states, the Associated Press analysis found. In Arizona, hospitals have been told to prepare for the worst. Texas has more hospitalized COVID-19 patients than at any time before, the analysis found. And the governor of North Carolina said recent jumps in cases caused him to rethink plans to reopen schools or businesses. In some states, more testing has uncovered more cases. But experts think at least some spikes are due to lifting stay-at-home orders, school and business closures, and other social distancing measures, the wire service reported. The increases aren’t coming in new cases only: At least nine states have seen spikes in hospitalizations since Memorial Day. In Arizona, 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. 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 Friday, the U.S. coronavirus case count had passed 2 million as the death toll neared 114,000. “It is a disaster that spreads,” Dr.…  read on >

Washing your hands more often may do more than slow the spread of COVID-19: New research suggests it also lowers your exposure to toxic flame retardants. How? Scientists found that halogenated flame retardants used in plastic TV cases can travel from the TV to indoor air and dust, then to hands, and then to electronic devices such as cellphones. That means that you can be exposed to these chemicals every time you touch your cellphone, according to the study published June 9 in the journal Environmental Science & Technology Letters. Halogenated flame retardants, such as polybrominated diphenyl ethers, are known to be a health risk to children. Previous research has shown that exposure to these chemicals can cause lower IQ and behavioral problems in children. “It’s well-known that viruses are transferred between surfaces and hands,” said study co-author Miriam Diamond, a professor in the University of Toronto’s department of earth sciences. “Our study shows that toxic chemicals like flame retardants do the same. That’s another reason we should all wash our hands often and well,” Diamond said in a university news release. Study co-author Lisa Melymuk, an assistant professor of environmental chemistry at Masaryk University in the Czech Republic, noted that “if a flame retardant is used in the TVs, we then find it throughout the house, including on the hands of the resident.” And…  read on >

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 >

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 >

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 >

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 >

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 >

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.

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 >
