Q: "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."

Q: The system preserves the most amount of natural bone, making it a less invasive way to treat diseased joints. Kalamazoo, Michigan-based Stryker, one of the top makers of reconstructive implants, said its system, called Triathlon PKR, is beneficial because it allows surgeons to provide personalized solutions by only shaving off diseased parts of the knee rather than replacing larger parts of it, or the entire knee joint. Partial knee resurfacing requires less operating time than total keep replacements and there is a shorter recovery period, with some patients leaving the hospital in less than 24 hours, Stryker said. Because less bone is removed, there is often less trauma to soft tissue during surgery, which may leave the patient with a more natural feeling knee than with a total knee replacement, the company added.

Q: According to the Maine Center for Disease Control, the number of syphilis cases reported in the state increased from 48 in 2016 to 84 last year. The number of national syphilis cases increased by 18 percent in between 2015 and 2016. Maine Department of Health and Human Services spokeswoman tells the Bangor Daily News the department isn't sure why syphilis has increased in recent years. Portland Public Health Center medical director Dr. Christina DeMatteo believes opioid use and waning concerns about HIV have contributed to attitudes about having unprotected sex. Public health advocates say budget cuts resulting in changes in prevention and treatment have also affected rates in the state. ___ Information from: Bangor Daily News, http://www.bangordailynews.com
