A prospective study by U.K. researchers found that adolescents who are double-jointedmedically termed joint hypermobilityare at greater risk for developing musculoskeletal pain as they get older, particularly in the shoulders, knees, ankles and feet. Findings published in Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR), indicate that children with joint hypermobility are approximately twice as likely to develop pain at these joints.
When ligaments are loose (ligamentous laxity) it may cause joints to extend beyond the normal range (hypermobility), with studies showing a possible genetic basis. However, when genetic causes are not found and joint pain is present, doctors may use the term 'benign joint hypermobility syndrome.' Several studies have shown that joint pain is common in children with hypermobility, with some reports as high as 74% of children with joint hypermobility experiencing pain. Yet, other research suggests that while musculoskeletal pain is a frequent complaint in adolescents, it is no more common in those with joint hypermobility.
"With such conflicting evidence we set out to determine whether adolescents with joint hypermobility are at risk of developing musculoskeletal pain," explains lead author Professor Jon Tobias from the University of Bristol, UK. In a study funded by Arthritis Research UK, the team recruited participants from the Avon Longitudinal Study of Parents and Children (ALSPAC), also known as Children of the 90s. Joint hypermobility was determined at roughly age 14 by a Beighton score of 6 or more out of a possible 9. Individual joints were determined to be hypermobile if, for example, the knees could be bent backwards or the thumbs could touch the wrist. At nearly age 18, participants were evaluated for joint pain by questionnaire.
Analysis of participants with complete data was conducted, with 1267 boys and 1634 girls evaluated. Approximately 5% of participants were hypermobile at age 14, and at age 18 close to 45% of participants reported any pain lasting one or more days. Joint hypermobility was associated with approximately a two-fold increased risk of moderately severe pain at the shoulder, knee, ankle and foot. Interestingly, this increased risk was particularly marked in obese participants, with over a ten-fold increased risk of knee pain observed in obese participants with hypermobility, possibly reflecting the role of mechanical factors.
Professor Tobias concludes, "Our study provides the first prospective evidence that adolescents who display joint hypermobility are at increased risk of developing musculoskeletal pain as they get older, particularly in the shoulder, knee, ankle or feet. Further investigation of increased joint pain in teens is warranted to determine if the long-term effects of joint hypermobility puts them at risk for developing osteoarthritis later in life."

Hands-on with Tizen 2.0 on Samsung's developer handset (video)
Shuffle along, shuffle along, because this couch is about to get crowded. Alongside the big four, we now have Ubuntu, Firefox OS and the latest version of Tizen all elbowing each other for room. Tizen has one particularly strong backer, Samsung, who built the reference device we play with in the video after the break, and whereas Firefox OS is destined only for the low-end, Tizen seems far more ambitious -- at least judging from the 720p resolution of this developer handset. Since the introduction of version 2.0, the OS is designed to run both native and HTML5 apps, or apps which mix the two layers -- such as the Vimeo app you'll see in the video, which has a web-based interface but accesses the hardware for the purpose of video acceleration.
Huge swathes of the interface are remarkable only by their familiarity: a home screen with a grid of apps; a single navigation button to take you back to this screen or alternatively to a multi-tasking screen by way of a long press; and a top-to-bottom pull-down for notifications and quick access to settings. It's basic, but it represents pretty much what all these new operating systems are supposed to be: ways of getting functionality that is at least close to Android but without all the licensing costs associated with running Google services. Beyond that, however, Tizen at least seems capable of delivering smartphone fundamentals like a fast camera (with burst mode, incidentally). Tizen's mostly likely rival will be Ubuntu, at least once that other Linux-based OS progresses beyond entry-level phones at some point in 2014.
From the sound of it though, Tizen is about to beat it to the punch.

U.S. tourist who was missing in Peru sends greetings from military base
SAN FRANCISCO (Reuters) - One of two California tourists in Peru feared by family to have been kidnapped sent home her first online greeting in a month on Wednesday, saying she and her boyfriend were safe on a military base, playing with a monkey and being treated like celebrities.
The Facebook message was posted a day after the Peruvian government said Jamie Neal and her traveling companion, Garrett Hand, both 25, had surfaced on a riverboat in the Amazon, surprised to learn they were the subjects of an international search.
"Everyone is interviewing us and taking photos, saying that we are now famous in Peru," Neal wrote from a military installation at Pantoja, in northern Peru near the border with Ecuador, where she said she and Hand had been taken.
"The Peruvian military gave us our own house to stay in and food and a bunch of booze to drink," Neal said, adding, "This is ... insane." She also said Peruvian tourism officials planned to fly a plane to Pantoja on Thursday to meet "us and bring us gifts."
Hand later posted a separate greeting on his own Facebook page, saying simply, "I'm alive."
It was not clear why the couple were brought to a military base, and tourism officials in Lima, the Peruvian capital, were not immediately available for comment.
Neal apologized for worrying friends and family with her disappearance but said that she and Hand had been traveling through remote villages in the Amazon without electricity, telephones or Internet service.
MAKING FRIENDS WITH A MONKEY
The couple were still unable to make a phone call via Skype because of slow Internet connections at the base, she said, adding they would call home when it was possible.
Neal concluded her message saying she was "going to go play with the pet monkey we named Pepe ... he was just biting my toes."
The Oakland, California, couple embarked on an open-ended bicycle tour of South America in late November. Relatives said that after hearing from the couple regularly, all communication from the pair stopped on January 25, along with activity on their bank accounts.
Relatives and co-workers expressed fears that Hand and Neal might have been abducted.
At the time, the couple were traveling to Lima from Cusco, a mountainous region near the ancient Incan city of Machu Picchu, where U.S. tourists were recently advised of kidnapping risks linked to a turf war between government forces and Maoist Shining Path rebels.
Peruvian officials launched a search for Neal and Hand shortly after they were reported missing and announced on Tuesday that the couple were found safe in Angoteros, Peru, on a boat up the Napo River headed for Ecuador.
Francine Fitzgerald, Hand's mother, said she would still fear for the couple's safety until she talked to them on the phone and saw a recent photo of them.
"We need to insist that an American citizen government official is witness to this supposed meeting that is going to occur sometime within the next day or two," the Hand family said in a statement early on Wednesday.
The Hand and Neal families did not respond to interview requests on Wednesday.
Peru's minister of tourism told CNN he was "deeply concerned" that the media attention caused by the missing couple would negatively affect his country.

What Caused the Solomon Islands Earthquake & Tsunami?
The deadly earthquake and tsunami that hit the Solomon Islands today struck along a subduction zone, the same geologic setting responsible for the world's most powerful earthquakes.
In a subduction zone, two of Earth's tectonic plates meet and one slides beneath the other into the mantle, the deeper layer beneath the crust. The Solomon Islands sits above the collision between the Australia and Pacific plates. In the region of today's magnitude-8.0 earthquake, the Australia plates dives beneath the Pacific plate toward the east-northeast at a geologically speedy 3.7 inches (94 millimeters) per year, according to the Incorporated Research Institutions for Seismology (IRIS).
The earthquake hit at a depth of 17.8 miles (28.7 kilometers) and was the second largest earthquake in the Solomon Islands region in almost 40 years, IRIS said in a statement. Several aftershocks followed, the largest measuring magnitude 6.6, according to the U.S. Geological Survey (USGS).
The tsunami generated by the quake, reported as 3 feet (0.9 meters) in height, hit villages on Santa Cruz Island, destroying structures and homes, according to news reports. A tsunami watch was issued for Australia, Indonesia and New Zealand, but not for the rest of the Pacific, according to the West Coast and Alaska Tsunami Warning Center.
Subduction zone quakes shove the seafloor in one sudden movement, which may generate a tsunami by pushing the ocean water above. However, depending on the depth and size of the earthquake, the actual seafloor surface may not move a significant amount, so a big earthquake doesn't always produce a massive wave.For example, a magnitude-7.6 subduction zone earthquake in the Philippines in August 2012, which started deep in Earth's crust, did not trigger a tsunami.
There were dozens of earthquakes around the Solomon Islands in the month leading up to today's massive quake, the USGS reported. More than 40 magnitude-4.5 quakes shook the islands in the past week alone, and seven of those temblors were larger than a magnitude-6.0, the USGS said.
