Several days after Sacramento County declined to bring charges against two police officers who shot and killed Stephon Clark last year in his grandmother's backyard, California's top prosecutor announced a similar decision.Police said they fired at Clark because they believed he was pointing a gun at them, but only a cellphone was found at the scene.State Attorney General Xavier Becerra said Tuesday that his office conducted its own investigation and could not find evidence the officers acted illegally."There's a young man who's no longer alive, with two sons who won't have a father, whose mother I just met with, who's grieving. Of course it was a tough call They're all tough calls. It's never easy," he told reporters. "But we have to do the job before us."The fatal shooting and the decisions of authorities not to charge the officers have prompted protests in the California capital.Dozens of demonstrators bearing photos of Clark and holding Black Lives Matter signs were arrested Monday night. A total of 84 people were arrested and cited, police said.Sacramento Police Capt. Norm Leong, who live-tweeted the protest, said the arrests were for unlawful assembly. He also said that 1207

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

SAN FRANCISCO, Calif. – Some shoe companies are doing their part to help the healthcare workers on the front lines of the coronavirus pandemic. Both Allbirds and Keen Footwear have donated thousands of pairs of shoes to hospital staff and others who are needed to work during this time of crisis. Allbirds says it distributed 0,000 worth of “Wool Runners” to those in the healthcare community after announcing the free shoes last Friday. Unfortunately, the company says its pledge to provide the free shoes uncovered a need beyond what they can fulfill on their own while ensuring they balance the needs of their employees. So, Allbirds is turning to the public to help them continue to give away shoes to those protecting our communities during this difficult time. The company is now offering a “buy-one-give-one” offer in the U.S.“As of today, and while supplies last, if you purchase a pair of Allbirds in the U.S., we will also split the cost of donating a pair of Wool Runners. Or if you’d like to simply donate a pair, we’ve created an option that allows you to do that too,” 1098
