Magnesium may be as important to kids' bone health as calcium

May 5, 2013 ? Parents are advised to make sure their children drink milk and eat other calcium-rich foods to build strong bones. Soon, they also may be urged to make sure their kids eat salmon, almonds and other foods high in magnesium -- another nutrient that may play an important role in bone health, according to a study to be presented Sunday, May 5, at the Pediatric Academic Societies (PAS) annual meeting in Washington, DC.

"Lots of nutrients are key for children to have healthy bones. One of these appears to be magnesium," said lead author Steven A. Abrams MD, FAAP, professor of pediatrics at Baylor College of Medicine in Houston. "Calcium is important, but, except for those children and adolescents with very low intakes, may not be more important than magnesium."

While it is known that magnesium is important for bone health in adults, few studies have looked at whether magnesium intake and absorption are related to bone mineral content in young children. This study aimed to fill that gap.

Researchers recruited 63 healthy children ages 4 to 8 years old who were not taking any multivitamins or minerals to participate in the study. Children were hospitalized overnight twice so their calcium and magnesium levels could be measured.

Participants filled out food diaries prior to hospitalization. All foods and beverages served during their hospital stay contained the same amount of calcium and magnesium they consumed in a typical day based on the diaries. Foods and beverages were weighed before and after each meal to determine how much calcium and magnesium the subjects actually consumed. In addition, parents were given scales to weigh their child's food for three days at home after the first inpatient stay and for three days at home prior to the second inpatient stay so that dietary intake of calcium and magnesium could be calculated accurately.

While hospitalized, children's levels of calcium and magnesium were measured using a technique that involved giving them non-radioactive forms of magnesium and calcium, called stable isotopes, intravenously and orally. Urine was collected for 72 hours. By measuring the stable isotopes in the urine, the researchers could determine how much calcium and magnesium were absorbed into the body. Bone mineral content and density were measured using total body dual-energy X-ray absorptiometry.

Results showed that the amounts of magnesium consumed and absorbed were key predictors of how much bone children had. Dietary calcium intake, however, was not significantly associated with total bone mineral content or density.

"We believe it is important for children to have a balanced, healthy diet with good sources of minerals, including both calcium and magnesium," Dr. Abrams concluded.

Twitter gives API 1.0 a reprieve, lets it live until June 11th

Twitter gives API 10 apps a reprieve, lets them live until June 11th

Those who preferred Twitter's earlier, more liberal ways have regarded May 7th with a sense of dread, as that's when API 1.0 (and our chance at a truly competitive app ecosystem) was supposed to go dark. While the company isn't about to reverse course, it is giving the refuseniks a break by delaying the shutdown until June 11th. More time is necessary for blackout tests, Twitter says. We wouldn't lean too heavily on remaining API 1.0-era apps and services when that instability exists, but the extra month does allow for a gentler transition into API 1.1's brave new world.

Pressure on Bangladesh, retailers to fix factories

DHAKA, Bangladesh (AP) ? In the aftermath of a building collapse that killed more than 530 people, Bangladesh's garment manufacturers may face a choice of reform or perish.

Home to five factories that supplied clothing to retailers in Europe and the United States, the shoddily constructed building's collapse has put a focus on the high human price paid when Bangladeshi government ineptitude, Western consumer apathy and global retailing's drive for the lowest cost of production intersect.

Officials said Saturday that more than 530 bodies have been pulled from the wreckage of the eight-story Rana Plaza building that collapsed nine days ago, sparking desperate rescue efforts, a national outpouring of grief and violent street protests.

The tragedy followed the deaths of 112 people five months ago in a blaze that swept through the Tazreen Fashions garment factory in Dhaka and the death of seven in a January blaze.

With three disasters in quick succession, the reputation of Bangladesh's $20 billion garment industry, already notorious for its low wages and dismal safety record, has plummeted. International clothing brands and retailers that said they could ensure worker safety in developing countries through self-regulation such as factory inspections have also suffered a blow to their credibility.

Now, Bangladesh's garment manufacturers fear that a backlash has been set in motion that threatens fortunes and livelihoods in a business that employs more than 3 million people and accounts for about 80 percent of the impoverished country's exports.

"It's a crucial time for us," said Atiqul Islam, president of the Bangladesh Garment Manufacturers and Exporters Association. "We are doing our best to improve the safety measures in the factories. We expect our buyers to bear with us and help us to overcome the current crisis. It's not the time to turn away from us. That will hurt the industry and many of the workers will lose jobs."

The most potent warning so far has come from the European Union, which said it could restrict Bangladesh's access to the crucial EU market if it fails to immediately take steps to ensure that basic labor standards are enforced.

Bangladesh is a member of Europe's "Everything But Arms" program for the world's poorest nations that exempts it from quotas and tariffs on all exports to the 27-nation EU except armaments. The EU is Bangladesh's single biggest market with exports of 8 billion euros in 2011, the bulk of which was garments shipped for European retailers.

"The sheer scale of this disaster and the alleged criminality around the building's construction is finally becoming clear to the world," EU foreign policy chief Catherine Ashton and trade commissioner Karel De Gucht said in an April 30 statement. They said they want any EU action to "incentivize" responsible management of the garment industry in Bangladesh.

The United States is reviewing Bangladesh's preferential trade status, a lengthy process that gained urgency after the killing last year of a Bangladeshi labor rights organizer who had campaigned for years to improve factory safety. Garments are not included in the American trade preferences for Bangladesh but loss of its special market access would further taint its reputation in the U.S., its second largest export market.

As a U.S. decision nears, the building collapse gives additional momentum to members of Congress who wrote to Bangladeshi Prime Minister Shiekh Hasina to protest a climate of fear created by the killing of Aminul Islam, the labor organizer, and lobbied then-U.S. Trade Representative Ron Kirk to speed up a review of Bangladesh's trade access following the Tazreen fire.

Signs of dissension are also emerging among clothing brands and retailers who as a group have usually sought to distance themselves from industry disasters.

The chief executive of Canada's Loblaw Inc., which owns the Joe Fresh clothing line that was being made in Rana Plaza, decried the response of "deafening silence" from what he said were more than two dozen other international retailers who used garment factories in the collapsed building.

Following the Tazreen fire where Walt Disney Co. branded clothing was found, the company in March added Bangladesh to a list of countries where it prohibits any of its clothing or merchandize from being produced.

The Bangladeshi garment association met earlier this week with representatives of 40 garment buyers including H&M, JC Penny, Gap, Nike, Li & Fung and Tesco. It said the companies have doubts about whether the industry can meet their production deadlines because of the disasters and political turmoil.

"The reality is that buyers are seriously thinking about their sourcing from Bangladesh," said Jenefa Jabbar, regional director of JC Penny, according to a garment association statement.

"Bangladesh government has laws, but there is no implementation of those laws. Buyers' community wants to see credible action," she was quoted as saying.

The retailers themselves are criticized by labor groups for allegedly shoveling blame and making token efforts to ensure worker safety.

A report by the AFL-CIO umbrella group of American unions published a day before the building collapse says retailers' intermittent factory inspections and corporate social responsibility reports have failed, and hold "eerie parallels" with the financial self-regulation that helped precipitate the global financial crisis.

The Bangladesh government, however, may be the least willing of all to accept any responsibility.

"I am not worried," Finance Minister Abul Maal Abdul Muhith said Friday. "These are individual cases of ... accidents. It happens everywhere."

Commuting Is No Sweat on These Swanky E-Bikes

With gas prices hovering around $4 a gallon and what seems an entire generation shunning automobiles, it's no wonder that bike commuting has seen such a resurgence in recent years. But for all the physical and environmental benefits riding imparts, it nevertheless leaves you a hot, sweaty mess. That is, of course, unless you get your bike to do the pedaling for you.

A2B bikes is the American arm of the HERO Eco Group, which has been making electric bikes for Indian and European markets since the turn of the century. The A2B lineup boasts five models with a variety of pedal assist and throttle options to minimize commuting effort. I recently took a ride on four of the models at A2B's showroom in downtown San Francisco.

Shima

The Shima's 500W wheel-hub propulsion system provides a roughly 37 mile range per 5 hour charge of its 36v 13.2ah Lithium-ion battery. That battery slides in and out under the rear deck and can be locked in place when you park. Three levels of pedal assist?economy, standard, and speed racer?provide up to 35 Nm of torque and propels the rider to speeds approaching 30 MPH. It's 7-speed Shimano gear set is relatively short and with the pedal assist at max, I routinely beat traffic off the line and passed other riders with ease. It felt like I was perpetually riding downhill. The Shima retails for $3,800.

All of the models include integrated head and tail lights and are all currently available.

Alva

The Alva is another pedal assist model, designed for comfort where the Shima was built for speed. Its 36v, 13.2ah Lithium-ion battery drives a 450W brushless hub motor to reach speeds of 20 MPH and a range of 20 miles. While the Shima's pedal assist was powerful enough to get off the line without too much trouble, the Alva takes a more on-demand approach. Located just under the bell on the left handlebar, there's a rocker switch that manually engages the motor without requiring you to push off or pedal start. That way you get a little bit of speed going before you start pedaling and eliminates the need to huff and puff through the first two gears. The Alva will set you back a $4,000.

Alva +

The Alva+ takes the features that made the Alva so popular in Europe and recalibrates them for lazy Americans. It offers pedal assist like its predecessor but upgrades the start button into a full-on throttle integrated into the right handlebar so you'll never have to pedal through the low gears. The Alva+ tops out at about 20 MPH under just throttle power but when you start pedalling as well, you can reach about 24 MPH, easily keep pace with city traffic over the bike's 37 mile range. The key fob security system?needed to turn on or adjust the power assist level?is ingenious as the A+ weighs a 66 pounds and challenging to ride without it. They may take your bike, but they won't get more than a few blocks with it. The Alva+ costs $4,000 as well.

Octave

Kyle Langdon, A2B's Business Operations Manager, described the Octave as the Escalade of E-Bikes. The man does not lie, the Octave is downright luxurious?like a Beach Cruiser you don't have to pedal. See, the cranks are set forward on the frame far ahead of the seat, like a Cruiser. This eases the rider into a more upright and comfortable sitting position, almost like a recumbent. Sure, that position makes pushing hard with your legs nearly impossible but it does not matter because you won't actually be doing much pedaling. I rode this bike for a good 20 minutes and pedaled none times?Zero?I just kept grabbing handfuls of throttle instead. The primary battery is located internally and delivers 15-20 MPH and 20 miles of range, though it can be augmented with a secondary battery on the rear deck, which boosts range to a possible 40 miles. It, too, runs $4,000 .
