Special counsel Robert Mueller's confidential report on the Russia investigation is more than 300 pages, according to a Justice Department official and a second source with knowledge of the matter.The Justice Department official described the still-secret report as more than 300 pages, while a second official said it was between 300 and 400 pages, not including exhibits.The page length had been a mystery in the days following the announcement that Mueller had concluded his work last Friday, as the Justice Department continually declined to comment on the page count but called it "comprehensive." Attorney General Bill Barr's four-page summary of Mueller's report provided only few details of how it is structured, describing it as "divided into two parts."Even many members of Congress have been kept in the dark about the breadth of the report until recently.A Justice official confirmed that Barr discussed the page length on a call with House Judiciary Chairman Rep. Jerry Nadler on Wednesday. Nadler would only say the report was "very substantial" and less than 1,000 pages when asked by reporters.Barr on Sunday released a four-page memo stating that Mueller's investigation did not establish that the Trump campaign conspired with the Russian government before the election, but Democrats have demanded to see Mueller's full report and the underlying evidence.A small team at the Justice Department is working on determining what portions of the report can be made public, after scrubbing it for grand jury and other material related to ongoing investigations. 1586

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

TAMPA, Fla. — A man arrested on Friday is accused of shooting and killing a Florida couple on Halloween, just days after they welcomed a new baby. Tampa police say Tyrail Kendrick, 26, is facing two first-degree murder charges in the deaths of Stanley Peck and Tia Pittman. Police responded to the 1700 block of West Walnut Street shortly after 7 a.m. on Oct. 31 after receiving a report of shots heard in the area.After arriving, they found Peck and Pittman suffering from gunshot wounds. Peck was pronounced dead at the scene and Pittman was taken to a local hospital where she died from her injuries. 616

SAN FRANCISCO — Federal and state officials in California were preparing Monday to receive thousands of people from a cruise ship that was idling off the coast of San Francisco with at least 21 people aboard infected with the coronavirus. The ship docked around midday Monday as officials prepared to begin to slowly disembark passengers and crew. The process could take several days. Fences were being installed at an 11-acre site at the Port of Oakland, as authorities readied flights and buses to whisk the more than 2,000 passengers aboard the Grand Princess to military bases or their home countries for a 14-day quarantine. There are more than 3,500 passengers on the ship, who hail from 54 countries. Questions have surrounded the cruise ship since reports surfaced last week that one person had died of COVID-19 aboard the ship. After the cases of the virus were concerned, the ship has attempted to quarantine passengers in their rooms and asked the passengers to practice "social distancing" by standing about six feet away from each other.Princess Cruises also operated the Diamond Princess, a ship that was moored for weeks in February off the coast of Japan after passengers tested positive for the coronavirus. Ultimately, about 700 passengers tested positive for the virus and seven people died.The quarantine practices used on the Diamond Princess have been questioned since passengers disembarked.The U.S. death toll from the virus reached at least 21 and the number of cases worldwide soared above 110,000. 1538
