Input: Consider Input: Paragraph: "Ed Stafford of Leicestershire, England walks in between trees as he walks through the Amazon jungle in Brazil in this undated handout photo. Former British army captain Stafford became on Monday the first known person to walk from the origin of the Amazon river, the world's second-longest river, to its mouth, after withstanding ""50,000"" mosquito bites, scorpion attacks and skin disease in his 859 day odyssey. REUTERS/Handout Ed Stafford, a 34-year-old from Leicestershire, England, dived into the Atlantic Ocean after taking 859 days to walk the length of the world’s second-longest river, starting at the peak of Mount Mismi in Peru in April 2008. “It’s just phenomenal to be here at the end of the journey after 2-1/2 years slogging our way through the jungle,” he told Reuters after arriving at the beach about 90 miles northeast of the Brazilian city of Belem. “It was really difficult to envisage how this was going to feel and I’m completely overwhelmed.”   Stafford briefly collapsed from exhaustion with only 52 miles of the 6,000-mile journey to go, passing out by the roadside after breaking out in a rash. “I feel slightly humbled that my system just decided to shut down so close to the finish,” he wrote on his blog at www.walkingtheamazon.com. Stafford has aimed to use the walk to raise awareness about the threats to the Amazon rain forest and its people, using a portable satellite video to blog about his trek. He had planned to complete the walk in about a year, but the journey was prolonged by floods that forced him to walk a roundabout route that was 2,000 miles longer than the 4,000-mile (6,400-km) length of the Amazon, which is exceeded in length only by Africa’s Nile river. He began the journey with fellow British adventurer Luke Collyer, but the pair had a falling out early in the trek and Stafford continued alone. He was joined in July 2008 by a Peruvian forestry worker, Gadiel Cho Sanchez Rivera, who pledged to walk with him for five days and has been with him on the walk ever since. A statement from Stafford’s media team said that the Briton had been: “wrongly accused of murder on two separate occasions, been imprisoned, had concrete stuffed in his mouth by hostile tribes people, been chased by Ashaninka Indians with bows and arrows, been stung by hundreds of wasps and watched as his guide ‘Cho’ removed a botfly from Ed’s head with superglue and a tree spine.”   It said he had endured “50,000” mosquito bites, lived on a diet of piranha fish, rice and beans, and dodged a variety of snakes, electric eels, scorpions, and ants, as well as contracting a skin-disfiguring disease. Famed British explorer Sir Ranulph Fiennes was quoted as saying in the statement that Stafford’s feat was “truly extraordinary.”   “No one has ever done this before and the pundits considered the route impossible,” he said." Claim: British man becomes first to walk Amazon length.

Output: A former British army captain became on Monday the first known person to walk from the origin of the Amazon river to its mouth, after enduring “50,000” mosquito bites, attacks by hostile Indians and tropical disease in his nearly 2-1/2 year odyssey.


Input: Consider Input: Paragraph: Use of such pills, which include Sanofi SA’s Ambien and other similar drugs, was significantly higher for those in their 50s as well as age 80 and older, according to the findings from the Centers for Disease Control and Prevention. Overall about 8.6 million people, or 4 percent of U.S. adults reported recently using sleep medication, CDC’s National Center for Health Statistics said in a report. But data showed higher use among middle-aged adults ages 50 to 59 and the elderly. Six percent of those ages 50 to 59 said they had taken a prescription sleep pill in the last 30 days, and 7 percent of those age 80 and older reported such use. In between, the numbers dip slightly below 6 percent for those in their 60s and 70s. In comparison, just 2 percent of those aged 20-39 said they had recently taken a sleep aid. CDC researcher Yinong Chong said people in their 50s could have trouble sleeping because of work and family stress. “It gives the picture of a sandwiched group who has family, not only children but also probably elderly parents but still you’re likely to be in the workforce, so you get squeezed at both ends in terms of family responsibility and job responsibility,” she said. Sleep may improve when people retire before potential chronic health problems kick in and begin interfering with sleep, Chong said, adding more study is needed. The data also showed that 5 percent of women surveyed said they had recently taken a sleep aid compared to about 3 percent of male respondents, according to CDC’s report. Chong said it was not clear why women were more likely to use the drugs. While previous data have tracked prescriptions dispensed for sleep aids, the CDC said its study is the first based on a survey of actual use of such drugs. Researchers for the Atlanta-based health agency’s National Center for Health Statistics questioned a sampling of adults age 20 and older about whether they had used prescription sleep aids within the last 30 days and asked participants to show interviewers the prescription medication. “You get how many people are actually using them,” Chong said in an interview, noting that prescription data could include multiple prescriptions for one patient or prescriptions that are never filled or even used. “This is actual use.”  Prescription sleep aids have become somewhat controversial because their effect can linger even after some patients wake up. The U.S. Food and Drug Administration has begun taking a closer look at sleep drugs, ordering lower-doses for Ambien and similar pills amid concerns that their active ingredient remained in patients’ blood the following morning at levels high enough to make driving and other activities dangerous. And just last month, the FDA rejected an experimental sleep drug from Merck & Co Inc, saying the proposed doses were not safe but that a lower-dose version might be acceptable. Not surprisingly, respondents to CDC’s study who said they slept five hours or less each night or those diagnosed with a sleep disorder were more likely to report using prescription aids. Additionally, more whites and people with higher levels of education also reported greater use, the agency said. Socioeconomic factors are likely behind those numbers, Chong said, since patients must be able to afford a doctor’s care and the medication. According to prescription data from IMS Health, Ambien and other versions of the drug zolpidem was ranked 15th among the most dispensed medications in the United States. Claim: Use of sleeping pills highest among older Americans: CDC.

Output: Older U.S. adults, particularly women, are more likely to use prescription sleep medications to try to get the minimum seven hours of sleep experts generally recommend, U.S. data released on Thursday showed.


Input: Consider Input: Paragraph: The story accurately represents the cost of the scans, which are often not covered by insurance. The story could have mentioned that once a scan finds something suspicious, biopsies and/or follow-up scans are needed at regular intervals, driving up the costs. These additional scans are typically covered by insurance. The evidence doesn’t show a clear estimate of survival benefit, which the story made clear. The story mentions that CT scanning could lead to unnecessary harms and procedures. The story could have specifically mentioned radiation exposure. The story does a good job of describing the current study and the controversy around the results. The story does not exaggerate the seriousness or prevalence of lung cancer. The story quotes multiple experts who provide valuable perspective. The story accurately describes that there aren’t really any alternatives to preventing death from lung cancer other than quitting smoking. Lung CT scans are clearly available. Clearly screening for lung cancer is not a new idea. Because the story quotes multiple experts, it’s clear that the story did not rely on a press release as the sole source of information. Claim: Shades of gray: Debate continues over diagnostic scans for lung cancer


Output: The idea of lung cancer screening is certainly appealing. Lung cancer is common and deadly, very often found too late for treatment to be effective. So what if you could find it early? Unfortunately the results of studies on CT screening haven’t supported this fully and the largest and most rigorous study to date is still years away from providing answers. This story does an excellent job of describing the promise and controversy of lung cancer screening. It presents the results of the contradictory studies and explains why some experts are hesitant to apply the conclusions of the 2006 study to policy decisions mandating screening. The story accurately represents the cost of the scans, which are often not covered by insurance. The story could have mentioned that once a scan finds something suspicious, follow-up scans are needed at regular intervals, driving up the costs. These additional scans are typically covered by insurance. Overall, a fine piece of reporting, following up on a state court ruling.
