Video: Doctors ignore blood pressure guidelines, study says

When a patient?s blood pressure is measured in both arms, instead of just one, the differences in readings could point to underlying health risks. NBC?s Dr. Nancy Snyderman reports.

>>> as we mentioned earlier, the health news has to do with a basic staple of the doctor's office, getting your blood pressure checked. if your last time at the doctor they only measured it on one arm, well, new research says they're doing it wrong. further, they say, doing it right could reveal a big health risk. our report from our chief medical editor dr. nancy snyderman .

>> reporter: doctors who measure blood pressure in only one arm may be missing critical information about their patient's heart health. a new study published in the journal "the lancet" shows the differences in blood pressure readings between both arms could point to underlying health risks. if the systolic pressure , the top number in a reading which measures the pressure in the artery where the heart beats , differs by 15 points in each arm, this study shows that a person is at 2.5 times higher risk of prefrl vas car disease, meaning blood vessels in the handed a feet are more likely to become blocked. risk of stroke is 1.6 times higher. risk from death of heart attack is 70% higher. some risk factors for hypertension are ages, genetics, age and obesity. your doctor should take blood pressure in each arm. if it's high in one arm, have that blood pressure repeated because some people develop something we call white coat hypertension . they go to their doctors, they're nervous, blood pressure goes up and settles down after a short time. brian, if that's not you and your blood pressure stays up, that's the time you go on and have further tests. it's amazing how many people have falsely elevated blood pressure and don't know it.

>> that's the effect.

>> it's that white coat .

EU leaders seek growth as Greece case looms (AP)

BRUSSELS ? European leaders were trying Monday to come up with ways to boost economic growth and jobs, which are being squeezed by their own governments' steep budget cuts across the continent.

The 27 EU leaders meeting in Brussels were also looking for common ground on a new treaty to toughen spending rules to dig the continent out of a crippling debt crisis. The elephant in the room, though, will be Greece.

Greece and its bondholders have come closer to a deal to significantly reduce the country's debt and pave the way for it to receive a much-needed euro130 billion ($170 billion) bailout.

Negotiators for the bondholders said Saturday that a debt-reduction deal could become final within the next week. If the agreement works as planned, it could help Greece avoid a catastrophic default, which would be a blow to Europe's already weak financial system.

But European officials are afraid that even that deal may not be enough to fix Greece's finances, with some blaming Athens for dithering in its austerity promises.

German officials over the weekend proposed that Athens temporarily cede control over tax and spending decisions to a powerful eurozone budget commissioner before it can secure further bailouts.

The idea proved immediately controversial ? both the European Commission and the Greek government refuted it ? to the point that German Chancellor Angela Merkel pulled back on the idea when she arrived in Brussels.

She said Europe had to support Greece in implementing promised austerity and reform measures, "but all that will only work if Greece and all other states discuss this together."

Though vital to turning around Europe's crisis, the negotiations in Greece don't resolve the weakening economic conditions across Europe as countries rein in spending to get their debts under control.

Front and center in Monday's discussions will be the continent's increasingly tough labor market.

Many now fear that Europe is on the verge of another recession, and leaders gathering Brussels said that spurring growth would be the focus of their talks Monday.

The big question is where to find money to boost growth when governments are trying to reduce debt.

"We have to have balanced budgets and at the same time focus on growth and jobs," said Prime Minister Helle Thorning-Schmidt of Denmark, which holds the rotating presidency of European Council. "It is possible to both at the same time and it is important to understand that these are two sides of the same coin."

Unemployment is rising steadily. In Spain, it has soared to nearly 23 percent and closed in on 50 percent for those under age 25, leaving more than 5 million people ? or almost one out of every four ? out of work as the country slides toward recession.

To help jump-start the EU toward more growth and employment, the European Commission is proposing to the summit leaders to redirect euro82 billion in existing development funds toward countries in dire need of help to fix their labor market.

The 27 heads of state and government got a taste of the popular frustration with austerity and high unemployment on their way to Monday's summit in a city paralyzed by strikes. Leaders had to fly into the military airport of Beauvechain 20 miles (30 kilometers) outside of Brussels after the city's main airport was shutdown by a 24-hour strike.

Belgium's three main unions joined hands in the walkout to protest national budgetary measures that have in part been imposed on the country by the EU. If the country hadn't met cost-cutting targets, financial sanctions would have been imposed.

Monday's strike has been mirrored in many other member states. Overall, 23 million people are jobless across the EU, 10 percent of the active population.

"Europe has to offer jobs, social protection and perspective for the future. Otherwise it risks losing the support of its citizens," said the strike manifesto of the ACV union.

Gunmen attack police station in Nigeria's Kano (Reuters)

KANO, Nigeria (Reuters) ? Gunmen bombed a police station on Sunday outside Nigeria's second city Kano, the police and witnesses said, leading to an hour of gunbattles in a region plagued by attacks from Islamist sect Boko Haram.

Kano state and its capital city of 10 million people have been under siege by gunmen from Boko Haram, which wants to impose sharia law across Nigeria.

"We were able to push them out of the area but they burnt part of the police station," Kano police commissioner Ibrahim Idris said. "It was a blast that caused damage to the station."

Boko Haram's attacks have become more sophisticated and deadly in Africa's top oil producer. A series of gun and bomb attacks, mostly on police stations, killed 186 people in Kano on January 20.

Witnesses said gunmen and armed police were in a shoot out for around an hour after the explosion at the police station at Naibawa district outside Kano.

"We are scared. The police and Boko Haram members are battling each other and there is gunfire everywhere," Usman Ibrahim Bello, a local resident told Reuters.

In an audio tape posted on the Internet on Thursday, the purported leader of Boko Haram, Abubakar Shekau, threatened to kill more security personnel and kidnap their families, and accused U.S. President Barack Obama of waging war on Islam.

Boko Haram, a movement loosely modelled on the Afghan Taliban whose name translates as "Western education is sinful," has been behind almost daily killings in its home base in the largely Muslim northeast. Its violence has spread west into other parts of the north and the capital Abuja since last year.

Madonna says charity plans 10 schools in Malawi (omg!)

NEW YORK (AP) ? Nearly six years after it was created, Madonna's Raising Malawi charity is set to break ground on the construction of schools in the impoverished country, but they will be run by the local community, not the superstar's organization.

According to organizers, work on the first school will start on March 30 in the Kasungu area, about 80 miles from the capital of Lilongwe, and all of the schools should be built by June 2013. Raising Malawi is providing $300,000 to the non-governmental organization buildOn to develop the schools. They'll serve about 1,000 boys and girls in the southern African nation.

"This remains a very big priority in my life and I am excited that with the help of buildOn we can maintain our ongoing commitment to move forward efficiently," Madonna said in a statement provided to The Associated Press.

Raising Malawi had originally intended to build all-girls schools that the organization would run. But it faced several obstacles in its goal, including complaints from some local farmers that they had been moved off land that Raising Malawi intended to use for its mission. Raising Malawi also had difficulty getting title to the land and there were concerns about the high costs of construction.

The new plan calls for "simple structures" that will be more practical and better serve Raising Malawi's original mission, said Trevor Neilson, who is helping to direct the project as partner of the Global Philanthropy Group. The approach will allow the program to serve twice as many children as before, Madonna said.

"I have learned a great deal over the last few years and feel so much more confident that we can reach out goals to educate children in Malawi, especially young girls, in a much more efficient and practical way," she said. Madonna has adopted two children from Malawi.

BuildOn has already built more than 50 schools in Malawi and 427 schools worldwide.

"For schools to be successful, they need to have community ownership and leadership," Neilson said in an interview Friday. "Raising Malawi shouldn't be running schools in Malawi. Local communities in Malawi should be running those schools, so that's a big part of the shift."

BuildOn has been working in Malawi for almost 20 years, said spokeswoman Carrie Pena. The organization works closely with the community, and locals even volunteer the labor to build the schools, according to Pena.

"It's absolutely a community-owned school," she said.

Neilson praised Madonna for sticking with her plan to build schools for Malawi's children despite several setbacks for the star, who is the director of the new movie "W.E.," out next week, and is this year's Super Bowl performer. Madonna brought in Global Philanthropy to work with Raising Malawi more than a year ago and removed the involvement of the Kabbalah Centre. She has practiced Kabbalah, a form of Jewish mysticism.

"When the previous management team had those problems, I think a lot of people thought Madonna would give up," Neilson said "It would have been understandable, but instead she's going to reaching twice as many kids."

Researchers shed light on magnetic mystery of graphite

Friday, January 27, 2012

The physical property of magnetism has historically been associated with metals such as iron, nickel and cobalt; however, graphite ? an organic mineral made up of stacks of individual carbon sheets ? has baffled researchers in recent years by showing weak signs of magnetism.

The hunt for an explanation has not been without controversy, with several research groups proposing different theories. The most recent suggestion, published today, 27 January, in the journal EPL (Europhysics Letters), has been put forward by a research group from the University of Manchester that includes Nobel prize-winning scientist Professor Sir Andre Geim.

The research group, led by Dr Irina Grigorieva, found that magnetism in many commercially available graphite crystals is down to micron-sized clusters of predominantly iron that would usually be difficult to find unless the right instruments were used in a particular way.

Finding the way to make graphite magnetic could be the first step to utilising it as a bio-compatible magnet for use in medicine and biology as effective biosensors.

To arrive at their conclusions, the researchers firstly cut up a piece of commercially-available graphite into four sections and measured the magnetisation of each piece. Surprisingly, they found significant variations in the magnetism of each sample. It was reasonable for them to conclude that the magnetic response had to be caused by external factors, such as small impurities of another material.

To check this hypothesis, the researchers peered deep into the structure of the samples using a scanning electron microscope (SEM) ? a very powerful microscope that images samples by scanning it with a beam of electrons ? and found that there were unusually heavy particles positioned deep under the surface.

The majority of these particles were confirmed to be iron and titanium, using a technique known as X-ray microanalysis. As oxygen was also present, the particles were likely to be either magnetite or titanomagnetite, both of which are magnetic.

The researchers were also able to deduce how many magnetic particles would be needed, and how far apart they would need to be spaced in order to create the originally observed magnetism. The observations from their experiments agreed with their estimations, meaning the visualised magnetic particles could account for the whole magnetic signal in the sample.

Dr Grigorieva, said: "The excitement around the findings of ferromagnetism in graphite, i.e. pure carbon, is due to the fact that magnetism is not normally found in organic matter. If we can learn to create and control magnetism in carbon-based materials, especially graphene, this will be an important development for sensors and spintronics."

France wants faster NATO Afghanistan exit

France and Afghanistan agree NATO should speed up by a year its timetable for handing all combat operations to Afghan forces in 2013, President Nicolas Sarkozy said Friday, raising new questions about the unity of the Western military alliance.

Sarkozy also announced a faster-track exit for France, the fourth-largest contributor of troops in Afghanistan ? marking a distinct break from previous plans to adhere to the U.S. goal of withdrawing combat forces by the end of 2014. The proposal comes a week after four unarmed French troops were killed by an Afghan soldier described as a Taliban infiltrator.

Sarkozy, alongside Afghan President Hamid Karzai who was in Paris for a previously planned visit, said France had told the U.S. of its plan, and will present it at a Feb. 2-3 meeting of NATO defense ministers in Brussels. He said he would call President Barack Obama about it Saturday.

"We have decided in a common accord with President Karzai to ask NATO to consider a total handing of NATO combat missions to the Afghan army over the course of 2013," Sarkozy told reporters.

A sense of mission fatigue has been growing among some European contributors to the 10-year allied intervention in Afghanistan. The new idea floated by Sarkozy would accelerate a gradual drawdown of NATO troops that Obama has planned to see through until the end of 2014.

France's announcement could step up pressure in other European governments like Britain, Italy and Germany, which also have important roles in Afghanistan ? even if the U.S. has the lion's share by far. But the leaders of those European nations don't face elections anytime soon: Sarkozy does.

Sarkozy said France will withdraw combat troops by the end of 2013, a reversal from his repeated commitment in recent months to stick with other allies on a U.S.-led schedule.

At the same time, he said France will restart its training missions of Afghan troops Saturday. After the shootings Jan. 20, he immediately suspended the training and joint French military patrols with Afghan forces.

A senior U.S. defense official said on condition of anonymity because of the sensitivity of the issue that U.S. forces are continuing to plan to transition to the Afghans at the end of 2014, and that nothing has changed.

In Washington, U.S. State Department spokeswoman Victoria Nuland said the timetable announced by France was worked through by both the Afghans and NATO as part of efforts to transfer security authority to Afghanistan.

"We, obviously, want to continue to work together to ensure that this is implemented in a way that is consistent with the efforts of all of NATO to give increasing authority to the Afghans, and that it is smooth," she said.

Nuland said the U.S. was pleased the move was not "precipitous."

"So you know, this was a national decision of France. It was done in a managed way. We will all work with it. As the president has said, with regard to our own presence, we are working on 2014," she said.

"The alliance as a whole is working on 2014. But we are also going to work within this French decision," she added.

NATO reacted tersely to Sarkozy's statement.

"We have taken note of the statement," NATO spokeswoman Oana Lungescu said in Brussels.

Sarkozy said France will speed up its withdrawal timetable, pulling out 1,000 of its current 3,600 soldiers by year-end ? the previous target was 600 ? and bring all combat forces out by the end of 2013.

Karzai had said previously that the goal was to have Afghan security forces in charge of security across the entire nation by the end of 2014. Afghan forces started taking the lead for security in certain areas of the country last year and the plan has been to add more areas, as Afghan police and soldiers were deemed ready to take over from foreign forces.

According to drawdown plans already announced by the U.S. and more than a dozen other nations, the foreign military footprint in Afghanistan will shrink by an estimated 40,000 troops at the close of this year. Washington is pulling out the most ? 33,000 by the end of the year. That's one-third of 101,000 U.S. troops that were in Afghanistan in June, the peak of the U.S. military presence in the war, Pentagon figures show.

Sarkozy also said France would hand over authority in the strategic province of Kapisa east of Kabul, where nearly all French troops are deployed, to the Afghans in March.

"A new phase is starting with the Afghans in which civilian and development projects will progressively take the handoff from our military presence," Sarkozy said, adding Afghan security "is the business of Afghans."

Karzai, who praised the role of France and other NATO allies, didn't object when Sarkozy said the 2013 timetable was sought by the two countries.

But the Afghan leader appeared to suggest that it was a high-end target.

"Yes, Mr. President, it is right that Afghanistan has to provide for its own security and for the protection of its own people, and for the provision of law and order," Karzai said.

"We hope to finish the transition ? to complete this transition of authority to the Afghan forces, to the Afghan government, by the end of 2013 at the earliest ? or by the latest as has been agreed upon ? by the end of 2014," Karzai said.

The NATO-led international force in Afghanistan has been steadily handing over responsibility for security to the government's army and police ever since the alliance's last summit in Lisbon in 2010. There, NATO leaders decided to move the Afghans into the lead role in fighting the Taliban by 2014 and end the coalition's combat role.

Afghan forces have started a process of taking the lead in over half of the country's population of 30 million in terms of security, and the transition remains on track.

Britain and Germany said France's announcement didn't change their pullout plans.

Britain said it's keeping to plans to withdraw all its 9,500 troops from Afghanistan by the end of 2014.

"We set out our long-term plans for no combat role by the end of 2014," a Foreign Office spokesman said on customary condition of anonymity. "We have already set out plans for some withdrawals in 2012."

Prime Minister David Cameron will hold talks with Karzai on Saturday. The Foreign Office said their meeting "is about long-term partnership and commitment beyond 2014 and the need for progress on the political track."

In Berlin, a Foreign Ministry spokeswoman said Germany's government had recently affirmed its troops' mandate "with a wide majority."

"We are in agreement with the international goal to hand over security responsibility fully by the end of 2014 and withdraw combat troops," the spokeswoman said on customary condition of anonymity.

During Karzai's stop Thursday in Italy as part of his European tour, Premier Mario Monti said his country would give economic and civilian support after a 2014 withdrawal. The two signed a long-term cooperation agreement.

Sarkozy's government has been under political pressure to withdraw French troops before the United States' pegged pullout in 2014. Polls show most French want an early pullout ? and he may soon be up for re-election.

Francois Heisbourg, an analyst at the Paris-based Foundation for Strategic Research think tank, told The Associated Press this week that a quick exit would also pose logistical problems for French forces, who hope to bring home much of the heavy equipment they have deployed in Afghanistan.

Francois Hollande, the Socialist nominee for France's presidential elections, repeated on French TV on Thursday his hope to bring all French forces home this year. Polls show him leading the conservative Sarkozy, who has not formally announced whether he will run in the two-round election in April and May ? though most political observers believe he will.

Nick Witney, a senior policy fellow at the Paris-based European Council on Foreign Relations, said public support of the war in Europe started sliding fast after the coalition agreed to end the combat mission in 2014.

"It has become more and more difficult to justify every single casualty, since it's now clear that these are wasted lives," said Witney, a former head of the European Defense Agency.

"Most European policymakers realize that on a purely cost-benefit assessment, we would all leave Afghanistan tomorrow," Witney said, adding that "it's difficult for any single government to break with its allies without being accused of lack of solidarity."

At the news conference with Karzai, Sarkozy didn't respond to a reporter's question about whether he believed France's announcement could weaken the alliance.

New ideas sharpen focus for greener aircraft

ScienceDaily (Jan. 27, 2012) ? Leaner, greener flying machines for the year 2025 are on the drawing boards of three industry teams under contract to the NASA Aeronautics Research Mission Directorate's Environmentally Responsible Aviation Project.

Teams from The Boeing Company in Huntington Beach, Calif., Lockheed Martin in Palmdale, Calif., and Northrop Grumman in El Segundo, Calif., have spent the last year studying how to meet NASA goals to develop technology that would allow future aircraft to burn 50 percent less fuel than aircraft that entered service in 1998 (the baseline for the study), with 75 percent fewer harmful emissions; and to shrink the size of geographic areas affected by objectionable airport noise by 83 percent.

"The real challenge is we want to accomplish all these things simultaneously," said ERA project manager Fay Collier. "It's never been done before. We looked at some very difficult metrics and tried to push all those metrics down at the same time."

So NASA put that challenge to industry -- awarding a little less than $11 million to the three teams to assess what kinds of aircraft designs and technologies could help meet the goals. The companies have just given NASA their results.

"We'll be digesting the three studies and we'll be looking into what to do next," said Collier.

Boeing's advanced vehicle concept centers around the company's now familiar blended wing body design as seen in the sub-scale remotely piloted X-48, which has been wind tunnel tested at NASA's Langley Research Center and flown at NASA's Dryden Flight Research Center. One thing that makes this concept different from current airplanes is the placement of its Pratt & Whitney geared turbofan engines. The engines are on top of the plane's back end, flanked by two vertical tails to shield people on the ground from engine noise. The aircraft also would feature an advanced lightweight, damage tolerant, composite structure; technologies for reducing airframe noise; advanced flight controls; hybrid laminar flow control, which means surfaces designed to reduce drag; and long-span wings which improve fuel efficiency.

Lockheed Martin took an entirely different approach. Its engineers proposed a box wing design, in which a front wing mounted on the lower belly of the plane is joined at the tips to an aft wing mounted on top of the plane. The company has studied the box wing concept for three decades, but has been waiting for lightweight composite materials, landing gear technologies, hybrid laminar flow and other tools to make it a viable configuration. Lockheed's proposal combines the unique design with a Rolls Royce Liberty Works Ultra Fan Engine. This engine has a bypass ratio that is approximately five times greater than current engines, pushing the limits of turbofan technology.

Northrop Grumman chose to embrace a little of its company's history, going back to the 1930s and '40s, with its advanced vehicle concept. Its design is a flying wing, championed by Northrop founder Jack Northrop, and reminiscent of its B-2 aircraft. Four high-bypass engines, provided by Rolls Royce and embedded in the upper surface of the aerodynamically efficient wing would provide noise shielding. The company's expertise in building planes without the benefit of a stabilizing tail would be transferred to the commercial airline market. The Northrop proposal also incorporates advanced composite materials and engine and swept wing laminar flow control technologies.

What the studies revealed is that NASA's goals to reduce fuel consumption, emissions and noise are indeed challenging. The preliminary designs all met the pollution goal of eliminating landing and takeoff emissions of nitrogen oxides by 50 percent. All still have a little way to go to meet the other two challenges. All the designs were very close to a 50-percent fuel burn reduction, but noise reduction capabilities varied.

"All of the teams have done really great work during this conceptual design study," say Mark Mangelsdorf, ERA Project chief engineer. "Their results make me excited about how interesting and different the airplanes on the airport ramp could look in 20 years. Another great result of the study is that they have really helped us focus where to invest our research dollars over the next few years," he said.

NASA's ERA project officials say they believe all the goals can be met if small gains in noise and fuel consumption reduction can be achieved in addition to those projected in the industry studies. The results shed light on the technology and design hurdles airline manufacturers face in trying to design lean, green flying machines and will help guide NASA's environmentally responsible aviation investment strategy for the second half of its six-year project.

Kendall & Kylie Might Skip College, Dad Says

It's no surprise that the next generation of Kardashians are poised to follow in the footsteps of their superstar reality TV siblings, and according to father Bruce, young Kendall and Kylie will likely dash into the family business over the pursuit of higher education.

"By the time they graduate from high school, they will probably be in a position to go right to working," Bruce told Us Weekly. "If they want to go to college, certainly, I think it's a good idea. But I'm not the advocate of, 'You've got to go to college!'"

Regarding Kendall, papa Jenner recognizes that the teen has identified a calling in design and modeling at her tender age and probably won't hit the books after she receives her high school diploma.

"I don't know if college is going to be that important for her," he explains. "She'll probably have a career by the time she's out of high school? If that's what she wants to do, that's good."

Following genetic footprints out of Africa

A new study, using genetic analysis to look for clues about human migration over sixty thousand years ago, suggests that the first modern humans settled in Arabia on their way from the Horn of Africa to the rest of the world.

Led by the University of Leeds and the University of Porto in Portugal, the study is published today in American Journal of Human Genetics and provides intriguing insight into the earliest stages of modern human migration, say the researchers.

"A major unanswered question regarding the dispersal of modern humans around the world concerns the geographical site of the first steps out of Africa," explains Dr Lusa Pereira from the Institute of Molecular Pathology and Immunology of the University of Porto (IPATIMUP). "One popular model predicts that the early stages of the dispersal took place across the Red Sea to southern Arabia, but direct genetic evidence has been thin on the ground."

The international research team, which included colleagues from across Europe, Arabia and North Africa, analysed three of the earliest non-African maternal lineages. These early branches are associated with the time period when modern humans first successfully moved out of Africa.

Using mitochondrial DNA analysis, which traces the female line of descent and is useful for comparing relatedness between different populations, the researchers compared complete genomes from Arabia and the Near East with a database of hundreds more samples from Europe. They found evidence for an ancient ancestry within Arabia.

Professor Martin Richards of the University of Leeds' Faculty of Biological Sciences, said: "The timing and pattern of the migration of early modern humans has been a source of much debate and research. Our new results suggest that Arabia, rather than North Africa or the Near East, was the first staging-post in the spread of modern humans around the world."

The research was funded by the Portuguese Foundation for Science and Technology, the Leverhulme Trust, and the DeLaszlo Foundation.

A new study, using genetic analysis to look for clues about human migration over sixty thousand years ago, suggests that the first modern humans settled in Arabia on their way from the Horn of Africa to the rest of the world.

Led by the University of Leeds and the University of Porto in Portugal, the study is published today in American Journal of Human Genetics and provides intriguing insight into the earliest stages of modern human migration, say the researchers.

"A major unanswered question regarding the dispersal of modern humans around the world concerns the geographical site of the first steps out of Africa," explains Dr Lusa Pereira from the Institute of Molecular Pathology and Immunology of the University of Porto (IPATIMUP). "One popular model predicts that the early stages of the dispersal took place across the Red Sea to southern Arabia, but direct genetic evidence has been thin on the ground."

The international research team, which included colleagues from across Europe, Arabia and North Africa, analysed three of the earliest non-African maternal lineages. These early branches are associated with the time period when modern humans first successfully moved out of Africa.

Using mitochondrial DNA analysis, which traces the female line of descent and is useful for comparing relatedness between different populations, the researchers compared complete genomes from Arabia and the Near East with a database of hundreds more samples from Europe. They found evidence for an ancient ancestry within Arabia.

Professor Martin Richards of the University of Leeds' Faculty of Biological Sciences, said: "The timing and pattern of the migration of early modern humans has been a source of much debate and research. Our new results suggest that Arabia, rather than North Africa or the Near East, was the first staging-post in the spread of modern humans around the world."

Documentary makers spur calls to action at Sundance (Reuters)

PARK CITY, Utah (Reuters) ? Each year documentaries at the Sundance Film Festival are among the best movies here, and in 2012 nonfiction works on subjects from the healthcare crisis to the war on drugs and rape in the military are wowing crowds and spurring calls to action.

Sundance is the premiere U.S. film festival for movies made outside of Hollywood's mainstream studios, and it is among the world's elite gatherings for documentary makers. Sundance backer and activist Robert Redford, is an avid supporter of the form.

Oscar-winner "An Inconvenient Truth" debuted here, and as it did in boosting environmental causes, many other documentaries also use Sundance to launch social cause campaigns. Succinctly put: when documentaries talking at Sundance, people listen.

"If there's a well-made film about an issue, it's not just a great film the festival is showing, but an issue (Sundance) is putting on the front burner," said writer and director Kirby Dick, whose documentary on rape within the US military, "The Invisible War," had its world premiere at the festival.

Many of the documentaries here at Sundance 2012, which runs through January 29, tell of struggles facing ordinary and poor Americans. Some, like "Invisible War" shed light on a problem that was little-known before, while others take on broad topics.

Director Eugene Jarecki's "The House I Live In" tackles America's long, failed war on drugs. Jarecki, director of other nonfiction films such as "Why We Fight," critiques drug policies, courts, prisons and their impact on minorities.

Macky Alston highlights the struggles of homosexuality in organized religion in "Love Free or Die" in which he follows the Episcopal Church's first openly gay bishop, Gene Robinson, and his contentious battle for acceptance in the faith.

And "Escape Fire: The Fight to Rescue American Healthcare" points out that despite rising healthcare costs, the outcomes faced by patients often are worse than they have been in years.

"There's so much misunderstanding about what's wrong with healthcare, how we can fix it and how we can move forward," the film's co-director and producer Matthew Heineman told Reuters. "The goal of our film has been to clarify these issues -- why it's broken, why it doesn't fundamentally want to change and people out there who are trying to change it."

The film's co-director and producer Susan Froemke hoped the festival might be "a launching point for starting a movement and to understand how to change health in our country."

"TELL YOUR FRIENDS"

The filmmakers behind "Finding North," have similar hopes for their documentary, which focuses on the hunger problem in America. Directors Lori Silverbush and Kristi Jacobson implored their audience to take action at the film's premiere.

"The very first step is you came to see this movie," Silverbush told the crowd. "Now go and tell your friends because the zeitgeist will fix this. When we get the political will as a nation to end hunger, we will. We did it before."

With soup kitchens on the rise and one in six Americans not getting enough food, according to the film, "there's not a lot of action in (Washington) D.C. on the issue and we do hope that this film will change that," added Jacobson.

In Dick's "Invisible War," the filmmaker follows the shattered lives of servicewomen (and a few servicemen) who were assaulted by their fellow soldiers while enlisted. He felt compelled to tell their story for numerous reasons.

"The primary objective is to raise awareness. That's why we made this film," Dick told Reuters. "Over 500,000 women have been assaulted in the military and it is shocking to me that so few people know about it. I've never made a film where the subject matter was so secretive, so covered up."

Kirby said he wanted to let "let our county know that the people who are protecting us are not being protected" and to let survivors know that they are not alone. He hopes that the U.S. military, Congress and the White House will "step up and do the things that need to be done to change this."

With all the pressing issues affecting the U.S., Kirby believes that the voice of the documentarian is an important one and Sundance is crucial for allowing them that platform.

"There's a sense in this country that things need to change," he said. "Documentary filmmakers, along with others, are trying to reflect that, to sound the alarm, to put the word out."

Apple doubles iPhone sales in 1Q (AP)

NEW YORK ? The iPhone is taking over Apple.

For the first time, the device that changed how people use mobile phones, accounts for more than half of the behemoth company's sales.

Apple Inc. on Tuesday said it sold 37 million iPhones in the last three months of 2011, vastly exceeding analyst estimates and propelling the company to record quarterly results.

The phone accounted for 53 percent of Apple's revenue in the quarter. Though it has other hit products, like MacBooks and the iPad, they can't keep up with the iPhone, whose sales more than doubled over last year from an already high level.

The sales mean Apple is set to regain the position it briefly held earlier last year of being the world's largest maker of smartphones. Nokia Corp., the earlier No. 1, in transition to a new generation of smartphones, and more recent competitor Samsung Electronics Co. has announced preliminary figure of 35 million smartphones sold in the October to December period.

October saw Apple launching the iPhone 4S in the U.S. and some other countries. The phone was delayed for a few months, which meant that Apple's results for the July to September quarter were uncharacteristically tepid.

It came back with a vengeance in the holiday season. On Tuesday, Apple said net income in the fiscal first quarter, which ended Dec. 31, was $13.06 billion, or $13.87 per share. That was up 118 percent from $6 billion, or $6.43 per share, a year ago.

Analysts polled by FactSet were expecting earnings of $10.04 per share for the latest quarter, Apple's fiscal first.

Revenue was $46.33 billion, up 73 percent from a year ago. Analysts were expecting $38.9 billion.

"It was a pristine quarter," said ISI Group analyst Brian Marshall. "The investment community has never seen a company like this, inside or outside technology."

The stellar performance could re-establish Apple as the world's most valuable company, again toppling Exxon Mobil Corp. Apple first unseated Exxon last summer, and the two have been trading places since then.

Apple shares rose $30.67, or 7.3 percent, to $451.08 in extended trading, after the company released its results. If that rally sticks in Wednesday's regular trading sessions, Apple's market value will be hovering around $420 billion. Exxon's market value stood at $417.9 billion Tuesday, while Apple's was $391.9 billion at the end of regular trading.

Apple shipped 15.4 million iPads in the quarter, again more than doubling sales over the same quarter last year. The November launch of Amazon.com Inc.'s $199 Kindle Fire tablet didn't appear to put much of a dent in the iPad's sales, as some analysts predicted it would.

Chief Financial Officer Peter Oppenheimer said the company expects earnings of $8.50 per share in the current quarter, and sales of $32.5 billion. Both figures are above the average estimate of analysts polled by FactSet, even though Apple usually low-balls its estimates.

The Cupertino, Calif. company ended the quarter with a cash balance of a staggering $97.6 billion. That's more than enough to buy Citigroup Inc. outright, or issue a special dividend of $100 per Apple share.

For years, investors have been frustrated with Apple's unwillingness to put the cash to use, but complaints have been muted as Apple continues to generate record-breaking results and as the stock price keeps rising. Apple executives have said the cash hoard gives the company flexibility to make acquisitions and long-term supply deals.

Apple's results lifted shares of smaller companies that supply chips for the iPhone, like TriQuint Semiconductor, up 7.7 percent, Cirrus Logic Inc., up 6.8 percent, Broadcom Corp., up 4.2 percent, and Skyworks Solutions Inc., up 3.7 percent.

Apple co-founder and longtime CEO Steve Jobs died Oct. 5, just as the record-breaking quarter started.

Women report feeling pain more intensely than men

Monday, January 23, 2012

Women report more-intense pain than men in virtually every disease category, according to Stanford University School of Medicine investigators who mined a huge collection of electronic medical records to establish the broad gender difference to a high level of statistical significance.

Their study, to be published online Jan. 23 in the Journal of Pain, suggests that stronger efforts should be made to recruit women subjects in population and clinical studies in order to find out why this gender difference exists.

The study also shows the value of EMR data mining for research purposes. Using a novel database designed especially for research, the Stanford scientists examined more than 160,000 pain scores reported for more than 72,000 adult patients. From these, they extracted cases where disease-associated pain was first reported, and then stratified these findings by disease and gender.

"None of these data were initially collected for research, but this study shows that we can use it in that capacity," said Atul Butte, MD, PhD, the study's senior author.

The medical literature contains numerous reports indicating that women report more pain than men for one or another particular disease, noted Butte, a professor of systems medicine in pediatrics. "We're certainly not the first to find differences in pain among men and women. But we focused on pain intensity, whereas most previous studies have looked at prevalence: the percentage of men vs. women with a particular clinical problem who are in pain. To the best of our knowledge, this is the first-ever systematic use of data from electronic medical records to examine pain on this large a scale, or across such a broad range of diseases."

The study's first authors were Butte's graduate student Linda Liu and postdoctoral scholar David Ruau, PhD, who splits his time between Butte's group and that of co-author Martin Angst, MD, professor of anesthesia. David Clark, MD, PhD, a professor of anesthesia, was another co-author.

Electronic medical records are deployed in about 1-2 percent of hospitals now, but that should approach 100 percent within the next few years as the United States continues to move toward EMRs, Butte said. Thus, large-scale research using clinically collected data will become increasingly feasible.

In this case, the scientists tapped an existing data archive that has been designed specifically for ease of research: the Stanford Translational Research Integrated Database Environment, or STRIDE. Pioneered by the medical school's chief information officer, Henry Lowe, MD (who is also an associate professor of systems medicine in pediatrics and director of Stanford's Center for Clinical Informatics), STRIDE aggregates clinical data on patients cared for at Stanford Hospital & Clinics and Lucile Packard Children's Hospital, making this data searchable for approved research projects.

Butte's team selected only adult records and looked for gender-related differences in pain intensity as reported on 1-to-10 scales, in which a zero stands for "no pain" and 10 for "worst imaginable." Their search algorithm combed through de-identified EMR data for more than 72,000 patients, and came up with more than 160,000 instances, ranging across some 250 different disease categories, in which a pain score had been reported.

"If someone's reporting that they're in pain, they're probably going to be given medication, which might reduce any subsequently measured pain score," said Butte. To get pain estimates that weren't as confounded by subsequent pain-relief medications or procedures, his group analyzed only the first pain-intensity score reported by a patient per encounter with a hospital-associated health professional.

The search identified 47 separate diagnostic categories for which there were more than 40 pain reports for each gender. The sample included more than 11,000 individual adult patients, of which 56 percent were women and 51 percent of them white. The researchers were able to further analyze these 47 categories by condensing them into 16 disease clusters: "musculoskeletal and connective tissue" (in which the biggest gender differences in reported pain intensity were observed), "circulatory" and so forth.

"We saw higher pain scores for female patients practically across the board," said Butte. Those reported differences were not only statistically significant, but also clinically significant. "In many cases, the reported difference approached a full point on the 1-to-10 scale. How big is that? A pain-score improvement of one point is what clinical researchers view as indicating that a pain medication is working."

While the overall results tended to confirm previous clinical findings ? for example, that female fibromyalgia or migraine patients report more pain than their male counterparts ? the search also unearthed previously unreported gender differences in pain intensity for particular diseases, for example acute sinusitis and "cervical spine disorders," more commonly known as neck pain.

The study's results come with a few caveats. First, the investigators made the assumption that patients' pain hadn't already been treated?for example, that they hadn't already self-medicated with over-the-counter painkillers ? by the time they showed up in the emergency room, doctor's office or neighborhood health clinic (or, equivalently, that the men and women were equally likely to have done so).

Other possible confounders include the setting in which pain was reported, Butte said. "Will an 18-year-old male report the same pain intensity with or without his mom present, or in the presence of a male vs. a female nurse? We can't be sure." But the sheer size of the study probably washes these concerns out at least to some extent, he said.

The third caveat is perhaps the most controversial. "It's still not clear if women actually feel more pain than men do," said Butte. "But they're certainly reporting more pain than men do. We don't know why. But it's not just a few diseases here and there, it's a bunch of them ? in fact, it may well turn out to be all of them. No matter what the disease, women appear to report more-intense levels of pain than men do."

To get to the bottom of this, Butte's team plans to search EMRs to see if they can find some objective measurement ? an already commonly measured blood-test variable, for instance ? that correlates highly with reported pain. "We want to find a biomarker for pain," he said.

Research recognized as 1 of Canada's top achievements in health research

You could call it paying it forward. A trip to the Emergency Department (ED) is every parent's worst nightmare. But what if the information documented as a result of your child's visit could help a child with similar symptoms a few provinces away?

Terry Klassen and his research team of leading pediatric emergency physicians at Pediatric Emergency Research of Canada (PERC) have done just that and the impact of their research is today recognized as one of the Top Canadian Achievements in Health Research in 2011. The award is bestowed jointly by the Canadian Institutes of Health Research (CIHR) and the Canadian Medical Association Journal (CMAJ).

Klassen, as Founding Director of PERC, generated important new knowledge that has substantially improved the outcomes of acutely ill or injured children seen in EDs in Canada and around the world. PERC has made key advances in three common childhood problems; croup, bronchiolitis, and mild head injuries. The most comprehensive achievement has had substantial influence on how croup is treated around the world.

Klassen is a Professor in the Department of Pediatrics and Child Health at the Faculty of Medicine and Director of Research for the Manitoba Institute of Child Health (MICH). The PERC team recognized with the award today include: David Johnson (University of Calgary), Martin Osmond (University of Ottawa), Amy Plint (University of Ottawa), and Lisa Hartling (University of Alberta).

"I congratulate Dr. Klassen and his colleagues across the country," said Dr. Digvir Jayas, Vice-President (Research and International) at the University of Manitoba. "This achievement is as a result of a national collaboration and putting evidence into practice for the benefit of all Canadians."

PERC recognized early on that many children with croup evaluated in general urban and rural EDs were not receiving optimal therapy. A series of randomized controlled trials found that the use of corticosteroids for children with mild, moderate, and severe croup was an effective use. Oral, intramuscular and inhaled doses have substantially cut the number of hospitalizations and return visits by half, resulting in reduced health care costs, parental stress and out-of-pocket expenses.

PERC has also been at the forefront of generating evidence for managing bronchiolitis. The group conducted the largest randomized controlled trial to date that involves infants with bronchiolitis. The study has shown that dexamethasonea class of steroid drugs used to treat many inflammatory and autoimmune conditionsand epinephrine (commonly known as adrenaline) may interact in ways that enhance or magnify one or more effects when combined; resulting in a significant drop in hospital admission rates.

One of the challenging issues that spawned the national-wide research network, which formed in 1995, was the huge variation in the use of computed tomography (CT) for children visiting EDs with cases of mild head injury. The CIHR funded study, that enrolled more than 4,000 child patients, resulted in a practical clinical decision rule that assists physicians in determining if a child suffering mild head injury requires a CT scan. This rule is currently being tested in 5000 more children and if validated could result in a decrease in the number of young children facing unnecessary radiation exposure and potential long-term associated risks.

The Top Canadian Achievements in Health Research acknowledges the discoveries and innovations that have had the biggest impact on the health of people in this country and around the world. A peer-review panel of Canadian and international experts selected the final list.

James' passion, great range remembered (AP)

NEW YORK ? On her last album "The Dreamer," released just three months before her death, Etta James sings a mix of covers, from the R&B classic "Misty Blue" to the Ray Charles song "In the Evening." But perhaps the most curious tune included on the disc may be the Guns N' Roses staple "Welcome to the Jungle."

That a 73-year-old icon of R&B would tackle the frenetic rock song ? albeit in a pace more fitting her blues roots ? might seem odd. But the song may be the best representation of James as both a singer and a person ? rambunctious in spirit, with the ability to sing whatever was thrown at her, whether it was jazz, blues, pining R&B or a song from one of the rowdiest bands in rock.

"She was able to dig so deep in kind of such a raw and unguarded place when she sang, and that's the power of gospel and blues and rhythm and blues. She brought that to all those beautiful standards and rocks songs that she did. All the number of vast albums she recorded, she covered such a wide variety of material that brought such unique phrasing and emotional depth," said Bonnie Raitt, a close friend, in an interview on Friday afternoon after James' death.

"I think that's what appealed to people, aside from the fact that her personality on and off the stage was so huge and irrepressible. She was ribald and raunchy and dignified, classy and strong and vulnerable all at the same time, which is what us as women really relate to."

James, whose signature song was the sweeping, jazz-tinged torch song "At Last," died in Los Angeles from complications of leukemia. Her death came after she struggled with dementia and other health problems, health issues that kept her from performing for the last two or so years of her life.

It was a life full of struggles. Her mother was immersed in a criminal life and left her to be raised by friends, she never knew her true father (though she believed it was billiards great Minnesota Fats), and she had her own troubles, which included a decades-long addiction to drugs, turbulent relationships, brushes with the law, and other tribulations.

One might think all of those problems would have weighted down James' spirit, and her voice, layering it with sadness, or despair. While she certainly could channel depression, anger, and sorrow in song, her voice was defined by its fiery passion: Far from beaten down, James embodied the fight of a woman who managed to claw her way back from the brink, again and again.

It's an attitude that influenced her look as well. Despite the conservative era, she dyed her hair platinum blonde, sending out the signal that she was far from demure, and owning a brassy, sassy attitude. She relished her role as saucy singer, a persona that she celebrated in her private life as well.

"In terms of 1950s rhythm and blues stars, she had kind of a gutsy attitude and she went out there and did what she did, and she was kind of bold ... and it had a huge influence," she said. "I think her gutsiness and her lack of fear and just her courage (made her special). ... I believe that made her important and memorable."

Beyonce, who played James in the movie "Cadillac Records" about Chess Records, also spoke about her influence on other singers.

"I feel like Etta James, first of all, was the first black woman I saw with platinum, blonde hair. She wore her leopard and she wore her sexy silhouette and she didn't care. She was strong and confident and always Etta James," said Beyonce in a 2008 interview.

James could often be irascible. Ritz remembers when he was working with her on the autobiography, touring with her around the country, one time he approached her with his tape recorder and she barked: "If see that tape recorder again I'm going to cram it up your (expletive)."

But at other times, she'd be effusive and warm and anxious to talk.

"Once she did talk, she was always candid and unguarded. She was a free spirit," Ritz said.

While Ritz put her in the category of other greats like Ray Charles, Aretha Franklin and Marvin Gaye, she never enjoyed their mainstream success. Though "At Last" has become an enduring classic, there were times when James had to scrounge for work, and while she won Grammys and was inducted into the Rock and Roll Hall of Fame, she did not have the riches, the multitude of platinum records or the hits that some of her peers enjoyed.

"She at least enjoyed a great resurgence like John Lee Hooker did and B.B. King, (and) has had some great decades of appreciation from new generations around the world," said Raitt. "There's no one like her. No one will ever replace Etta."

And Ritz said the lack of commercial success does nothing to diminish her greatness, or her legacy.

"Marvin certain knew it and Ray knew it ... the people who know that she was in that category," he said. "Whatever the marketplace did or didn't do or whether her lack of career management didn't do, it has nothing to do with her talent."

And on Friday, the Queen of Soul was among those who paid tribute to James greatness, calling her "one of the great soul singers of our generation. An American original!

"I loved `Pushover,' `At Last' and almost any and everything she recorded! When Etta SUNG, you heard it!"
