Paragraph: Torrential rain caused floods and triggered landslides in western Japan last week, bringing death and destruction to neighborhoods built decades ago near steep mountain slopes. At least 176 people were killed, the government said, with dozens missing in Japan’s worst weather disaster since 1982. In Kumano, a mountainside community in Hiroshima prefecture that was hit by a landslide last week, Ken Kirioka anxiously watched rescuers toiling through mud, sand and smashed houses to find the missing, including his 76-year-old father, Katsuharu. “He is old and has a heart condition. I prepared myself for the worst when I heard about the landslide on Friday night,” he said, pointing at a pile of mud and rubble where he said his father was buried. “He is an old-fashioned father who is hard-headed and does not talk much,” Kirioka said, adding he would stay until his father was found. “It would be too bad for him if a family member were not around”. Rescuers working under a scorching sun combed through heaps of wood and thickly caked mud in a search for bodies, helped by sniffer dogs. In some cases only the foundation of homes remained as they cut through debris with chain saws. With temperatures of 33 degrees Celsius (91 degrees Fahrenheit) or higher in the devastated areas in Okayama and Hiroshima prefectures, attention turned to preventing heat-stroke among rescue workers and in evacuation centers where thousands of people have sought shelter. People sat on thin mats on a gymnasium floor in one center, plastic bags of belongings piled around them and bedding folded off to the side. Portable fans turned slowly as children cried. Abe, who canceled an overseas trip to deal with the disaster, was criticized after a photograph posted on Twitter showed Abe and his defense minister at a party with lawmakers just as the rains intensified. After observing the damage from a helicopter flying over Okayama, one of the hardest-hit areas, Abe visited a crowded evacuation center. He crouched down on the floor to speak with people, many of them elderly, and asked about their health. He clasped one man’s hands as they spoke. Later he told reporters the government would do everything it could to help the survivors. “We’ll cut through all the bureaucracy to secure the goods people need for their lives, to improve life in the evacuation centers - such as air conditioners as the hot days continue - and then secure temporary housing and the other things people need to rebuild their lives,” he said. Abe is up for re-election as party leader in September and has seen his popularity ratings edge back up after taking a hit over a cronyism scandal earlier this year. His government pledged an initial $4 billion toward recovery on Tuesday, and a later special budget if needed. Officials turned to social media to warn of the additional danger of food-borne illnesses, urging people to wash their hands and take other measures against food poisoning. Evacuation orders were issued for 25 households in the city of Fukuyama after cracks were found in a reservoir. Water accumulating behind piles of debris blocking rivers also posed a danger after a swollen river rushed into a Fukuyama residential area on Monday, prompting more evacuation orders. The intensifying heat was expected to trigger thunderstorms on Wednesday, with authorities warning new landslides could be set off on mountainsides saturated with water. Japanese media on Wednesday focused on the timing of evacuation orders issued in the hard-hit Mabi district of Kurashiki city just minutes before a levee broke and water poured into the residential area. A number of the dead in Mabi were found in their homes, suggesting they did not have enough time to flee, media reports said. Claim: Japan PM visits flood disaster zone, promises help as new warnings issued.
Prime Minister Shinzo Abe visited flood-stricken parts of Japan on Wednesday as the death toll from the worst weather disaster in 36 years reached 176 and health concerns rose amid scorching heat and the threat of new floods.

Paragraph: HIIT can blast calories, build muscle and boost endurance with impressive efficiency in just 20 minutes a day, but the catch is finding the right level of intensity outside the comfort zone, fitness trainers say. Sean Bartram, author of the book “High Intensity Interval Training for Women,” said to find that level people should think about what it is like being chased by a rabid dog. “It’s just below that,” he said. “To gain maximum benefits you have to push your body to a place that’s almost uncomfortable.”   The American College of Sports Medicine predicts HIIT will be a top fitness trend in 2015. Bartram said people are drawn to it for its efficiency and almost endless variety of exercises. The bursts can be sprinting or spot jumps and the recovery can be rests or slower paced movements, he explained. “You could alternate 30 seconds of sprinting with 30 seconds of walking, or you could engage in a series of bodyweight exercises, such as push-ups, doing each for 30 seconds with 10 seconds of rest in between,” he said. Dr. Michele Olson, a professor of exercise science at Auburn University at Montgomery, Alabama, said it’s not high intensity unless the heart rate is elevated to near 90-plus percentage of its maximum. “Many people think they are engaging in HIIT but they are really doing traditional interval training, where the heart rate is around 75 to 85 percent of max,” she said. Maximum heart rate is about 220 minus age, according to the American Heart Association. Olson said that if done properly, HIIT can increase the effectiveness in losing abdominal fat and prompt favorable changes in cholesterol and insulin levels. “There is research showing that you can cut your exercise time nearly in half,” she said. About 20 minutes of HIIT can reap similar benefits of doing 35 to 40 minutes of moderate, steady-state cardio, she added, noting the training level must be intense. Hayley Zawadzki, personal training manager at New York Health and Racquet Club fitness centers, suggests that anyone starting HIIT should have a fitness analysis. “If you have a history of high blood pressure or medications, you cannot push to the absolute max,” she said. Claim: Key to High Intensity Interval Training found outside comfort zone.
With High Intensity Interval Training (HIIT), which consists of short bursts of intensive activity followed by short periods of  recovery, fitness experts say the harder the push, the greater the reward.

Paragraph: Sen. Charles Schumer of New York said the VA needs to provide Congress more information about a recent bulk order for $208,000 worth of hydroxychloroquine. President Donald Trump has heavily promoted the malaria drug, without evidence, as a treatment for COVID-19. Schumer’s request comes after a whistleblower complaint filed this past week by former Health and Human Services official Rick Bright alleged that the Trump administration, eager for a quick fix to the onslaught of the coronavirus, wanted to “flood” hot spots in New York and New Jersey with the drug. Major veterans organizations have urged VA to explain under what circumstances VA doctors initiate discussion of hydroxychloroquine with veterans as a treatment option. “There are concerns that they are using this drug when the medical evidence says it doesn’t help and could hurt,” Schumer said in an interview with The Associated Press. He said given the fact the malaria drug, despite being untested, had been repeatedly pushed publicly by Trump, VA Secretary Robert Wilkie must address whether anyone at the department was pressured by the White House or the administration to use hydroxychloroquine for COVID-19. Schumer said Wilkie also should answer questions about a recent analysis of VA hospital data that showed there were more deaths among patients given hydroxychloroquine versus standard care, including how much patients knew about the drug’s risks before taking it. In a statement Sunday, VA spokeswoman Christina Noel called it “preposterous” for anyone to suggest that VA would make treatment decisions based on anything other than “the best medical interests of patients.” “VA only permits use of the drug after ensuring veterans and caretakers are aware of potential risks associated with it, as we do with any other drug or treatment,” she said. Wilkie in recent weeks has denied that veterans were used as test subjects for the drug and that it was instead administered at government-run VA hospitals only when medically appropriate, with mutual consent between doctor and patient. Still, Wilkie and the department have repeatedly declined to say how widely the drug was being used for COVID-19, including how many veterans were given the drug, and whether VA doctors were given guidance by VA headquarters on specific scenarios when it should be used. In a weekly call with veterans’ groups this past week, Wilkie continued to defend VA’s use of hydroxychloroquine. He dismissed the recent analysis of VA hospital data showing no benefits to patients, suggesting the poor outcomes were because the cases involved older, very sick veterans. “Use of this medication for treatment of COVID-19 is considered ‘off label’ — perfectly legal and not rare,” he wrote in an April 29 letter to veterans’ groups. The analysis of hospital data, done by independent researchers at two universities with VA approval, was not a rigorous experiment. Researchers analyzed medical records of 368 older male veterans hospitalized with confirmed coronavirus infection at VA medical centers who died or were discharged by April 11. About 28% of veterans who were given hydroxychloroquine plus usual care died, versus 11% of those getting routine care alone. The VA recently said most of its recent bulk order for hydroxychloroquine was being used for approved uses, such as treating lupus and rheumatoid arthritis, but it didn’t provide breakdowns. Wilkie in recent weeks took advocacy of the drug even further than Trump by claiming without evidence that it has been effective for young and middle-aged veterans in particular. In fact, there is no published evidence showing that. Veterans are “very concerned that we still do not have clarity on the VA’s past and present use of hydroxychloroquine in treating veterans with COVID-19,” Jeremy Butler, chief executive officer of Iraq and Afghanistan Veterans of America, told the AP. “Now that the federal government issued an emergency use authorization for remdesivir to treat COVID-19, we need answers to these questions as well as the VA’s plans for administering, or not administering, remdesivir,” he said. That action by the Food and Drug Administration came after preliminary results from a government-sponsored study showed that remdesivir shortened the time to recovery by 31%, or about four days on average, for hospitalized COVID-19 patients. In a tweet Sunday, former VA Secretary David Shulkin urged the department to immediately curtail use of hydroxychloroquine for COVID-19. “With studies showing no benefit, VA should restrict use exclusively to clinical trials,” he wrote. Shulkin was fired by Trump in March 2018, and Wilkie replaced him. Schumer said his main concern is determining whether the VA had conducted any “clandestine studies to determine whether hydroxychloroquine was effective without their permission.” He said there’s also concern that the department won’t address specifically where the drug was sent. “These are people who risked their lives for us,” Schumer said. “They should be treated only with the utmost dignity, respect and high standards of care.” The drug has long been used to treat malaria and other ailments. A few, very small preliminary studies suggested it might help prevent the coronavirus from entering cells and possibly help patients clear the virus sooner. But the FDA last month warned doctors against prescribing the drug for COVID-19 outside hospitals because of the risks of serious side effects and death. Claim: Schumer calls on VA to explain use of unproven drug on vets.

The Senate’s top Democrat on Sunday called on the Department of Veterans Affairs to explain why it allowed the use of an unproven drug on veterans for the coronavirus, saying patients may have been put at unnecessary risk.
