Scans of the lungs of the sickest COVID-19 patients show distinctive patterns of infection, but so far those clues offer little help in predicting which patients will pull through. For now, doctors are relying on what’s called supportive care that’s standard for severe pneumonia.Doctors in areas still bracing for an onslaught of sick patients are scouring medical reports and hosting webinars with Chinese doctors to get the best advice on what works and what hasn’t.One thing that’s clear around the globe: Age makes a huge difference in survival. And one reason is that seniors’ lungs don’t have as much of what geriatrics expert Dr. Richard Baron calls reserve capacity.“At age 18, you have a lot of extra lung capacity you don’t use unless you’re running a marathon,” explained Baron, who heads the American Board of Internal Medicine. That capacity gradually declines with age even in otherwise healthy people, so “if you’re an old person, even a mild form can overwhelm your lungs if you don’t have enough reserve.”Here’s what scientists can say so far about treating those who become severely ill.HOW DOES COVID-19 HARM THE LUNGS?The new coronavirus, like most respiratory viruses, is spread by droplets from someone’s cough or sneeze. The vast majority of patients recover, most after experiencing mild or moderate symptoms such as fever and cough. But sometimes the virus makes its way deep into the lungs to cause pneumonia.Lungs contain grapelike clusters of tiny air sacs called alveoli. When you breathe, oxygen fills the sacs and passes straight into blood vessels that nestle alongside them. Pneumonia occurs when an infection -- of any sort, not just this new virus -- inflames the lungs’ sacs. In severe cases they fill with fluid, dead cells and other debris so oxygen can’t get through.If other countries have the same experience as China, about 5% of COVID-19 patients could become sick enough to require intensive careHOW DOES THAT DAMAGE APPEAR?Doctors at New York’s Mount Sinai Health System analyzed 121 chest CT scans shared by colleagues in China and spotted something unusual.Healthy lungs look mostly black on medical scans because they’re full of air. An early infection with bacterial pneumonia tends to show up as a white blotch in one section of one lung. Pneumonia caused by a virus can show up as hazy patches that go by a weird name -- “ground glass opacities.”In people who get COVID-19 pneumonia, that haze tends to cluster on the outside edge of both lungs, by the ribs, a distinctive pattern, said Dr. Adam Bernheim, a radiologist at Mount Sinai.As infection worsens, the haze forms rounder clusters and gradually turns more white as the air sacs become increasingly clogged.HOW TO TREAT THE PNEUMONIA?There are no drugs so far that directly attack the new coronavirus, although doctors are trying some experimentally, including an old malaria treatment and one under development to treat Ebola.“The best treatment we have is supportive care,” said Dr. Aimee Moulin, an emergency care physician at the University of California Davis Medical Center.That centers around assistance in breathing when the oxygen levels in patients’ blood starts to drop. For some people, oxygen delivered through a mask or tubes in the nose is enough. More severely ill patients will need a breathing machine.“The goal is to keep the person alive until the disease takes its course” and the lungs begin to heal, explained Mount Sinai’s Dr. Neil Schachter.The very worst cases develop an inflammatory condition called ARDS -- acute respiratory distress syndrome — that floods the lungs with fluid. That’s when the immune system’s attempt to fight infection “is going crazy and itself attacking the lung,” Baron explained.Many things besides the coronavirus can cause the condition, and regardless of the cause, it comes with a high risk of death.WHAT ELSE IS IMPACTED?Severe pneumonia of any sort can cause shock and other organ damage. But in a webinar last week, Chinese doctors told members of the American College of Cardiology to watch for some additional problems in severe COVID-19, especially in people with heart disease. The worst off may need blood thinners as their blood starts to abnormally clot, and the heart itself may sustain damage not just from lack of oxygen but from the inflammation engulfing the body.Another caution: The sickest patients can deteriorate rapidly, something a hospital in Kirkland, Washington, witnessed.Of 21 patients who needed critical care at Evergreen Hospital, 17 were moved into the ICU without 24 hours of hospital admission, doctors reported last week in the 4639

Siblings Mark and Lexy spent four years in foster care, but that all changed when they came to stay with Tom and Debra Crittenden. Now, the Georgia family has been together for two years.“The stars were aligned for us to adopt Mark and Lexy. They were literally the only kids we ever fostered; the only kids we ever met in the process," Tom Crittenden said. "So, it kind of seemed like they’re our kids."However, an adoption story like this one is not very common. Most people want to adopt babies, and at the ages of 15 and 17, Mark and Lexy almost aged out of the foster care system.Kimberly Offutt is the National Foster Care Adoption Director with Bethany Christian Services. She says the doors to the foster care system close to children once they reach the age of 18 leaving them in a very vulnerable position.“More than 10 percent of the kids who age out of foster care haven’t even graduated from high school," Offutt said. "Within two to three years, those children could end up homeless, incarcerated, where another system is now raised in them. Seven out of 10 of the young women actually have children that end up back in the foster care system."According to the U.S. Department of Health and Human Services, the longer a child is in foster care, the less likely they are to leave it before turning 18. “Our teenagers recognize that the clock is literally ticking. Every birthday is not a celebration. It is another year that they recognize, ‘if I don’t find a forever family, what’s going to happen to me,’” Offutt said.Offutt says a majority of U.S. children in foster care are between the ages of eight and 14, and the number of children in foster care continues to rise. The only hope in changing that statistic comes from families willing to take a leap like the Crittendens.“It’s just such a shame because it’s such a hindrance for these kids who age out of the system and don’t have that support network. Not just to get them through high school and college or whatever, but for the rest of their life,” Tom Crittenden said.The Crittendens say they understand people’s hesitation to adopt a teenager, but they believe you can still have a large impact on their lives. “We’re not bad. People always stereotype us saying that we have trouble and that we’re bad and stuff and how we’re like disobedient, and that’s not the case," Lexy said. "It’s actually what our parents did. That’s why we’re in foster care. Most of us are in foster care for what our parents did. Not for what we did."Thankfully, Mark and Lexy were able to stay together in their adoptive family.“Without siblings, ya know, we couldn’t really have that much fun. Because your parents are older than you, so having a close sibling is good,” Mark said.They’ve been given a new start with a new family. Debra says she loves introducing the kids to new experiences they’ve never had before.“We’ve taken them on trips. We were with them the first time they ever got on an airplane. We took them over to see the Grand Canyon and Sedona and ended up in Vegas," Debra Crittenden said. "And then, we took them out of the country to see the Caribbean about a month ago. So that’s fun, watching them experience new things that they wouldn’t have had access to."Mark and Lexy say they’d like to see other foster kids have the same opportunity.“To find someone that actually cares for them. To let them know that they are loved,” Mark said.There are 125,000 foster kids still waiting to be adopted.“If not you, who? If not now, when?” Offutt said. 3532

RICHMOND, Va. (AP) — Confederate monuments have become a target of protesters demonstrating against the police killing of George Floyd. As tense protests swelled across the country Saturday into early Sunday, monuments in Virginia, the Carolinas and Mississippi were defaced. The headquarters of the United Daughters of the Confederacy in Richmond also burned for a time and had graffiti scrawled on its exterior. The presence of Confederate monuments across the South and elsewhere in the United States has been challenged for years. Some of the targeted monuments have been under consideration for removal. In Tennessee and Pennsylvania, statues of people criticized for racist views, but without Confederate ties were also targeted. 747
