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

SEYMOUR — Hidden beneath the trees in a quiet Seymour, Indiana, neighborhood, Jessie Miligan showed where he picked up a baby, just hours old, with no mother in sight."There is a little bag over there. I see a little footprint pop out. I pick it up, I untie it and there is a little blanket covering its face," Miligan said. "So I pull it up and I am holding this little baby in a plastic bag, just back there. I don't know. I try not to judge, but there are way better ways of handling not being able to take care of a baby."It was an unusual sight to find in his neighborhood, or really anywhere."It is something that I never thought I would see in my life," Miligan said. "It is hard to believe that someone would tie a baby up and leave it outside. That baby more than likely would have froze to death. It's cold out."Miligan's mom, Angela Butler, first saw the baby while walking her dog, O.J. In disbelief, she said she went to grab her son and her phone to call 911 to get help for the baby."I told my boys, 'Go with me to make sure I am seeing what I am seeing,'" Butler said. "I had Jesse pick it up and, sure enough, it was a little newborn baby wrapped in a blanket. The blanket was covering its face and tied up, double-knotted, in a Walmart bag."Left alone and crying, Butler said just wrapping the baby in their arms while waiting for emergency crews to come provided some comfort to little one left to be found by a stranger."It was crying before we picked her up," Butler said. "And after we picked her up, she quit crying immediately."For this mother, it was a heartbreaking realization of what she just happened to stumble upon."It's sad knowing that the mother just dumped it off like it was a piece of trash," Butler said. "I don't see how anyone could do that to a child. Like, why would they put it in the woods? Just left it to die?"Seymour police announced Wednesday they identified and made contact with a person they wanted to interview in connection with the case, but there has not been any official update on the investigation.While it was by chance Butler came across the baby, she and her family left knowing they were able to change her future."It made me feel like I saved a life today," Butler said. "That that baby has a fighting chance to grow up and just to have a life." 2320

Residents along the Louisiana Coast are being encouraged to stay in shelter as Tropical Storm is making its final approach to the coast late Friday. As of 8 a.m. ET, Barry remains a strong tropical storm with top winds of 70 MPH. Its rainbands are moving onshore in Louisiana as it inches northwest at 5 mph, bringing a dangerous storm surge and possible tornadoes. Its slow trek means a longer period of heavy rainfall and flooding in the region that will last through next week, the center 504

Students from high schools around the country have been working to compete in a national engineering challenge, and it’s all focused around helping people with disabilities. STEM students from 50 high schools across America entered the SourceAmerica Design Challenge, where participants create innovative technology to help people with disabilities in the workplace. That's A Wrap deli in North Potomac, Maryland is known for employing people with disabilities. That's why these STEM students from Poolsville High School picked this place for their school project. The group is one of the five finalist teams for the national engineering competition. Learning all the back-end technology on their own, the students invented an iPad application called "Recipe Easy," which aims to help people with disabilities work more efficiently. The students took all of the recipes from That’s A Wrap and shot videos on how to make the food, before uploading them to the app. Step by step, each recipe is show in an animation and text. It’s also hands-free. "When you hold up a spatula, the camera will detect it and it will move to the next step of a recipe, so Steven has that as a guide for him," says junior Anjali Murthy on the help it provides one of the workers at the deli, Steven.Charissa Garcia with SourceAmerica says the students from the five finalist schools will present their devices on stage for a panel of judges. "They come together. They build a project to really focus on independence, empowerment, increased wages and increased employment opportunities for people with disabilities," Garcia explains of the program. Although these students from Poolsville High School want to take the trophy home, they say they already feel good about making an impact. More information about the program and finalists can be found 1839
