Q: Paragraph: The Midwest was the hardest-hit region, as temperatures plunged below zero Fahrenheit (minus 18 degrees Celsius). By nightfall the mercury was hovering at 0F in Chicago, 7F (minus 14C) in Detroit and minus 21f (minus 29C) in Minneapolis. Local television pictures showed the Chicago River and Lake Michigan filled with chunks of ice. The brutal blast known as the polar vortex is a stream of cold air that spins around the stratosphere over the North Pole, but whose current has been disrupted and is now pushing south into the United States. Officials warned Chicago residents, accustomed to chilling winters, to expect an unusually deep and dangerous freeze. Even the city's supply of its signature deep-dish pizza was affected: The Lou Malnati's chain announced it would stop taking delivery orders at 8 p.m. on Tuesday. "This could possibly be history-making," said Ricky Castro, a National Weather Service meteorologist in Romeoville, Illinois. As much as two feet (60 cm) of snow was forecast in Wisconsin, and six inches (15 cm) in Illinois. Snow was expected through Wednesday from the Great Lakes region into New England. Some Chicago residents found warmth inside the Harold Washington Library Center, which planned to stay open on Wednesday. Gilbert Rothschild, 79, walked through a corridor wearing three sweaters and an undershirt underneath his parka. "The more layers, the more you're insulated," he said. Rothschild, the president of a liquor retailer, said he planned on keeping his stores open on Wednesday, figuring customers who were not working might want to pick up something to keep them feeling warm at home. Many Midwest cities opened warming shelters. Regional governments closed hundreds of schools and airlines canceled more than 2,000 flights, according to the Flightaware flight tracking website. Many had been destined for Atlanta, where the National Football League's Super Bowl will take place on Sunday. Amy Patterson, a vice president at the Atlanta Super Bowl Host Committee, said there would still be time for fans to fly to Atlanta for the game, with the National Weather Service forecasting a high of a balmy 58F (14C) on Sunday. A low of minus 10F (minus 23C) was forecast in Chicago and elsewhere in northern Illinois on Wednesday. But with the wind chill factored in, temperatures will feel as low as minus 50F (minus 46C) through Thursday, the National Weather Service reported. Temperatures could reach lows of minus 30F to minus 40F (minus 34C to minus 40C) in parts of the Northern Plains and Great Lakes on Wednesday, the NWS said. The freezing weather may have killed a man in Rochester, Minnesota, who was found dead outside his home on Sunday, according to a report by WCCO, a local CBS affiliate. Rochester police officials did not respond to a request for comment. Jim Hayes, a National Weather Service meteorologist, warned that frostbite was possible within 10 minutes in the intense cold. For many across the region, life ground to a halt. In Chicago, home to the nation's third-largest school system, officials plan to cancel classes for all 360,000 students on Wednesday due to the weather. Detroit also said all public schools would close, and Michigan State University said it would suspend classes, only the seventh time it has done so because of weather since 1855. The Chicago Zoological Society said it would shut Brookfield Zoo for only the fourth time in its 85-year history on Tuesday and Wednesday. According to the National Weather Service, the coldest recorded temperature in Chicago was minus 27 degrees (minus 33C) on Jan. 20, 1985. Officials in Des Moines, Iowa, opened warming shelters, but also suggested residents could stay warm inside shopping malls. In Georgia, Governor Brian Kemp shut government offices in 35 counties on Tuesday, and schools across parts of the state were also closed. In Fargo, North Dakota, where the temperature dropped to minus 24F (minus 31C), Dan Hallock, an advertising executive, marveled that people were still working outside as he bought coffee. "The garbage men of Fargo have my utmost respect," he said. Claim: Polar vortex freezes U.S. Midwest with snow, dangerously cold air.

A: A blast of Arctic air from the polar vortex brought dangerous, bone-chilling cold to a wide swath of the United States on Tuesday, stretching from the Dakotas through Maine, with snow expected as far south as Alabama and Georgia.

Q: Paragraph: That's when the 37-year-old nurse and mother got scared for her family. "I couldn't sleep that night. I thought, 'If I brought this home to my mom, she's probably going to die, and it's probably going to be my fault.' So I had to find a different way," Neuburger said. To protect her family, Neuburger moved from her parents' home, where she had been living with her son after a recent divorce, and into a camper. Even though she doesn't know when she'll be able to hug her 11-year-old boy again, she's glad she chose to self-isolate especially since she began feeling sick five days after that hospital scare. Holed up in the camper as she awaits the results of a COVID-19 test, Neuburger is among countless doctors and nurses around the world who are choosing to move to hotels, tents, garages and other temporary housing to protect their loved ones even as they risk exposing themselves to a virus that has claimed tens of thousands of lives, including a number of medical workers. Hotels, some business owners and people who run Airbnb rental homes are among those offering lodging, sometimes for free, to doctors and nurses needing to self-isolate. Social media is full of efforts to match medical professionals with temporary housing. One Facebook group, RVs 4 MDs, connects RV owners with medical workers. In Ireland, a real estate company has used Instagram to offer up empty flats. The extra layer of isolation means those who are risking their own health to save the lives of others are now sacrificing even more as they resign themselves to virtual contact with their kids, parents, spouses and others they would normally fall back on for emotional support during this stressful time. "It's upsetting even though you know it's the right decision to leave your family," said Mica Sosa, a floor nurse at an oncology unit at a Phoenix hospital, who moved into a friend's empty condominium a few weeks ago. "It's so bizarre to turn around and walk away from the people you normally run to." Events Sosa knows she will miss: Easter with her 4-year-old son; her mom's 71st birthday; and her own 7th wedding anniversary. Some colleagues thought she was moving too soon. But with her mother's age and her own husband in his 60s, Sosa didn't want to wait until Phoenix had a surge in cases to take precautions. "Why wait until you are New York to get that radical? You need to protect yourself now," she said. "I think everyone needs to look at their own family situation and decide what's best for them." For most people, the new coronavirus causes mild or moderate symptoms, such as fever and cough that clear up in two to three weeks. But the virus can lead to more severe illness, including pneumonia, and death for some, especially older adults and people with existing health problems. Outside Portland, Maine, a pregnant Joy Engel is staying home with a toddler son while her husband, Dr. Ben Hagopian, lives in a friend's empty in-law apartment. "We fought hard for this pregnancy and we weren't willing to take the risk," Engel said. For Neuburger, the gravity of the coronavirus took hold in one shift in the intensive care unit at the Minnesota hospital where she works. She felt her mask leaking as she cared for one patient, but she kept doing her job and switched to a protective respiratory device when she could. Then came the patient whose ventilator tube came apart. On the way home from work, she called her dad. She told him to take her son, Xander Ponkin, upstairs, while she went directly to the basement where she had been staying. She kept away from the rest of her family until she could move into a camper two days later. "My dad made me give him a hug even though I didn't want to. He said, 'What happens if you get sick and die? I won't see you again,'" she said. She used Facebook to find the camper, and plans to pay its owner $200 a month. It's now parked in the driveway of her former in-laws, who are caring for Xander, in the Twin Cities suburb of St. Paul Park. She has been able to play with him in the yard at a distance. They also use video chat to play games, and she watches from her window as he shoots baskets outside. The hardest part, Neuburger said, is not being able to give him a hug. "I'm making the best of it. I'm trying to," she said. "Sometimes I just sit here and cry. But then I feel like I sleep better knowing I'm not possibly infecting my family." ___ Associated Press writer David Sharp in Portland, Maine, contributed to this report. Claim: Doctors, nurses leave homes to protect families from virus.

A: Lisa Neuburger was caring for a patient with the coronavirus when the person's ventilator tube became detached. As she worked to help the patient, she knew fluid from the person's lungs could be spraying into the air, possibly exposing her to the virus, despite the protective gear she was wearing.

Q: Paragraph: Forxiga can now be used along with insulin in patients with Type-1 diabetes and a Body Mass Index (BMI) of 27 or more when insulin alone has not been able to control blood sugar levels, the company said. Type-1 diabetes is a chronic condition in which the pancreas produces little or no insulin hormone. Farxiga or Forxiga, as the drug is known outside the United States, is one of AstraZeneca's top ten drugs by sales. It generated $1.39 billion in 2018, and is key to the company's future as it turns itself around. Claim: EU approves AstraZeneca's drug for adjunct use in Type-1 diabetes.

A:
British drugmaker AstraZeneca Plc said on Monday the European Commission approved its diabetes drug Forxiga for use as an oral supplement to insulin in adults with a rare type of the disease.
