Hip implants a bit more likely to fail in women


CHICAGO (AP) — Hip replacements are slightly more likely to fail in women than in men, according to one of the largest studies of its kind in U.S. patients. The risk of the implants failing is low, but women were 29 percent more likely than men to need a repeat surgery within the first three years.


The message for women considering hip replacement surgery remains unclear. It's not known which models of hip implants perform best in women, even though women make up the majority of the more than 400,000 Americans who have full or partial hip replacements each year to ease the pain and loss of mobility caused by arthritis or injuries.


"This is the first step in what has to be a much longer-term research strategy to figure out why women have worse experiences," said Diana Zuckerman, president of the nonprofit National Research Center for Women & Families. "Research in this area could save billions of dollars" and prevent patients from experiencing the pain and inconvenience of surgeries to fix hip implants that go wrong.


Researchers looked at more than 35,000 surgeries at 46 hospitals in the Kaiser Permanente health system. The research, published Monday in JAMA Internal Medicine, was funded by the U.S. Food and Drug Administration.


After an average of three years, 2.3 percent of the women and 1.9 percent of the men had undergone revision surgery to fix a problem with the original hip replacement. Problems included instability, infection, broken bones and loosening.


"There is an increased risk of failure in women compared to men," said lead author Maria Inacio, an epidemiologist at Southern California Permanente Medical Group in San Diego. "This is still a very small number of failures."


Women tend to have smaller joints and bones than men, and so they tend to need smaller artificial hips. Devices with smaller femoral heads — the ball-shaped part of the ball-and-socket joint in an artificial hip — are more likely to dislocate and require a surgical repair.


That explained some, but not all, of the difference between women and men in the study. It's not clear what else may have contributed to the gap. Co-author Dr. Monti Khatod, an orthopedic surgeon in Los Angeles, speculated that one factor may be a greater loss of bone density in women.


The failure of metal-on-metal hips was almost twice as high for women than in men. The once-popular models were promoted by manufacturers as being more durable than standard plastic or ceramic joints, but several high-profile recalls have led to a decrease in their use in recent years.


"Don't be fooled by hype about a new hip product," said Zuckerman, who wrote an accompanying commentary in the medical journal. "I would not choose the latest, greatest hip implant if I were a woman patient. ... At least if it's been for sale for a few years, there's more evidence for how well it's working."

Obama's Speech on Guns Doesn't Stop Ill. Killing












A Chicago teenager was shot and killed Friday only hours after her sister attended President Obama's speech on the city's rampant gun violence.
Janay McFarlane, 18, was killed while walking with a friend during a visit to her dad, Herbert McFarlane, in North Chicago.


"All this gun violence going on, you never think it would be your child," he told ABC's Chicago station WLS. "This is the hardest thing for me in my life."


Herbert McFarlane told WLS that the loss of Janay is especially hard because she leaves behind a 3-month old son, who likes to wear an "I love Mommy" shirt. The shooting occurred in Lake County, a northern suburb miles from the epicenter of the gun violence on the city's South Side.


"I'm in Lake County to get away from violence and now it happened in Lake County where I moved to," he told WLS.


McFarlane and her child spent time both in Lake County and on the South Side where her mother lives.

Only hours before McFarlane was shot and killed, President Obama returned to his hometown to speak on the South Side at a Hyde Park high school. McFarlane's sister, Destini Warren, 14, sat behind the president during the speech.


More than 500 people were shot and killed here last year, and this year the situation has worsened with the most deadly January the city has seen in over a decade. The shooting death of Hadiya Pendleton, a 15-year old who performed in Washington, D.C. at events connected to the president's inauguration last month, garnered national attention.


"Too many of our children are being taken away from us," Obama said in Hyde Park, with McFarlane's sister in the audience.


"Last year there were 443 murders with a firearm on the streets of this city, and 65 of those victims were 18 and under," he said. "So that's the equivalent of a Newtown every four months." He was referring to Newtown, Conn., where 20 first graders were gunned down by Adam Lanza along with seven adults.


Only hours later in Chicago, another 18-year old was shot and killed.


"I felt like someone took a knife and stabbed me in the heart, and a piece of my heart I will never get back," Angela Blakely, Janay McFarlane's mother, told WLS.


North Chicago Police on Sunday reportedly questioned two people in connection to McFarlane's death. Her family said McFarlane was an unintended target of the shooting.


Messages left by ABC News with the North Chicago Police Department and the Lake County Coroner's Office went unreturned Monday.


Another Chicago teenager, Frances Colon, was also shot and killed Friday just hours after she had told her father that she saw President Obama's helicopter fly over her neighborhood.

Ecuador's Correa cruises to re-election victory


QUITO (Reuters) - Ecuadorean President Rafael Correa swept to a re-election victory on Sunday that allows him to strengthen state control over the OPEC nation's economy and gives a timely boost to Latin America's alliance of socialist leaders.


The charismatic leftist had 57 percent support compared with 24 percent for runner-up Guillermo Lasso, with almost 40 percent of votes counted. The electoral authority said it did not expect the results to change significantly.


"Nobody can stop this revolution," a jubilant Correa told supporters from the balcony of the presidential palace, after claiming victory.


"The colonial powers are not in charge anymore. You can be sure that in this revolution it's Ecuadoreans in control."


The combative, U.S.-trained economist took power in 2007 and has won strong support among the poor by using booming oil revenues to build roads, hospitals and schools in rural areas and shantytowns.


"Our Ecuador needs a president like Rafael Correa. He has been strong and has not allowed anyone to intimidate him," said Julieta Moira, 46, who is unemployed, as she celebrated outside the presidential palace. "I'm very excited, happy and thankful."


Supporters also gathered in a park in the upscale north end of Quito, waving the signature neon-green flags of Correa's Alianza Pais party.


DEDICATES WIN TO CHAVEZ


Correa, 49, may now be in line to become Latin America's main anti-American voice and de facto leader of the ALBA bloc of leftist governments as Venezuelan President Hugo Chavez has been silenced during his battle with cancer.


Correa said he dedicated his victory to Chavez.


The principal challenge in Correa's new four-year term will be wooing investors needed to boost stagnant oil production and spur the mining industry. A $3.2 billion debt default in 2008 and aggressive oil contract negotiations scared off many.


Critics view Correa as an authoritarian leader who has curbed media freedom and appointed aides to top posts in the judiciary.


"This government has not given us anything good, only insults and taxes. We're tired of all that. I'm concerned that this government has alliances with communist countries," said Celeste Guerrero, a 68-year-old pensioner in Guayaquil.


Even some supporters disapprove of his tempestuous outbursts, confrontations with media and bullying of adversaries.


But the fractured opposition failed to make a consolidated challenge. It fielded seven candidates, making it easy for Correa, and he is now on track for a decade in office.


That is rare stability in a country where three presidents were pushed from office by coups or street protests in the decade before Correa took power in 2007.


He is already the longest-serving president since the return to democracy in the 1970s following a military dictatorship.


Correa's success has hinged in part on high oil prices that allowed for liberal state spending, including boosting cash handouts to 2 million people, and spurred solid economic growth.


He is likely to continue spending heavily to maintain his popularity, but state revenues would dry up if oil prices fell.


He now hopes to diversify the economy away from its dependence on oil, in part by bringing in new investment for the mining sector. Despite promising reserves of gold and copper, mining operations have barely gotten off the ground.


In a news conference on Sunday after polls closed, Correa played down the need for more foreign investment. He insisted the ultimate goal was to ensure economic growth rather than "mortgaging" the country to bring in cash from abroad.


"We welcome foreign investment, and we're already getting plenty of it," Correa said. "Ecuador is one of the most successful economies in Latin America."


Lasso, a wealthy ex-banker and Correa's closest rival, had tried to woo voters with promises of lower taxes. He congratulated Correa on his victory but also took pride in his Creo party taking a quarter of the vote.


"We are now the second-largest political force in the country," said Lasso, who was beaming despite losing.


CONGRESS BATTLE


The other six opposition candidates included former Correa ally Alberto Acosta, former President Lucio Gutierrez and banana magnate and five-time presidential candidate Alvaro Noboa.


Pollsters say some of them focused their campaigns too much on attacking Correa and failed to put forward concrete proposals to entice voters.


Ecuadoreans also chose a new Congress on Sunday.


The Alianza Pais party was expected to win a majority in the legislature, which would let Correa push ahead with controversial reforms, including a media law and changes to mining legislation, without having to negotiate with rivals.


The results of the vote for Congress are not expected to be known for several days, but Correa said he was confident.


"I think we are going to get a majority and we will manage that majority with great responsibility," he told Latin America's Telesur TV network, set up by Chavez and his allies as an alternative to established media.


Correa never shies away from a fight, be it with international bondholders, oil companies, local bankers, the Catholic Church or media that criticize his policies.


He vowed on Sunday to expand state regulations over media groups he has called "dogs" and "hired assassins."


"One of the things we have to fix is an unethical and unscrupulous press that wants to judge, legislate and govern," Correa said. "That goes against the rule of law and we will not allow it."


His criticism of the U.S. "empire" and his clashes with foreign investors and the World Bank have fueled Correa's popularity as a strong-minded leader who stands up to foreign powers that many say meddled in Ecuador's affairs for decades.


He took the global limelight last year when he granted asylum to WikiLeaks' founder Julian Assange. Critics say he did it to brush off accusations that he is curbing freedom of expression in Ecuador.

British Prime Minister David Cameron on India trade trip amid graft scandal

LONDON: British Prime Minister David Cameron arrives in India on Monday to try to win new investment in the face of fierce global competition as a scandal engulfs an Anglo-Italian helicopter deal.

Making his second visit to India as prime minister, Cameron's trip comes days after a similar trade mission by French President Francois Hollande, underlining how Europe's debt-stricken states are competing to tap into one of the world's fastest-growing economies.

His delegation, which includes representatives of over 100 companies, cultural and educational bodies, is the biggest taken abroad by a British prime minister and includes four ministers and nine lawmakers.

However, the timing of Cameron's trip is not ideal. India said on Friday it wanted to cancel a $750 million deal for a dozen helicopters made by AgustaWestland, the Anglo-Italian subsidiary of Italy's Finmeccanica, over bribery claims.

That will not make Cameron's job of persuading India to buy more civil and military hardware easier, and Indian officials have told the local press they intend to press Cameron for "a fully fledged report" on what Britain knows about the scandal.

Britain has said it wants to wait until the end of the Italian investigation before commenting in full, but has given India an interim report on the subject.

At a time when Britain's government is struggling to get its economy growing, officials see India, projected to become the world's third largest economy by 2050, as a key strategic partner in what Cameron has called a "Global Race".

"I think Britain and India can be one of the great partnerships of the 21st Century," he told the Hindustan Times. "India is going to be one of the great success stories of this century - a rising power in the world. And I want Britain to be one of your partners as you grow and succeed."

He is expected to remind the Indian government that the Eurofighter jet - which is partly built in Britain - remains an attractive option if New Delhi decides to review a multi-billion dollar deal to buy 126 French-made Rafale fighters.

A British government source said on Friday that London had noted that Hollande had not finalised the Rafale fighter jet deal during his own trip and that London would be asking how the talks with the French were going.

Companies travelling with Cameron include BP, BAE Systems, De La Rue, Diageo, EADS UK, HSBC, JCB, Lloyd's, the London Stock Exchange, London Underground, Rolls-Royce and Standard Chartered. He is also taking 30 small and medium-sized firms.

Colonial past

Cameron's visit to India, a country that won independence from Britain in 1947 and whose colonial history remains a sensitive subject for many Indians, will take in Mumbai and New Delhi.

Cameron says the two countries enjoy a "special relationship", a term usually reserved for Britain's ties with the United States, but it is a relationship undergoing profound change. For now, Britain's economy is the sixth largest in the world and India's the 10th. But India is forecast to overtake its old colonial master in the decades ahead.

TATA group, an Indian company that owns car maker Jaguar Land Rover, is now Britain's biggest employer in the manufacturing sector and, in a nod to how the relationship is evolving, London will stop giving India foreign aid after 2015.

Cameron is expected to lobby India to open up its economy to foreign investment to allow retailers, such as Britain's Tesco , to open outlets there amid frustration that many of the sectors in which British business excels remain partly or fully closed to foreign investors.

India is forecast to spend $1 trillion in the next five years on infrastructure and Britain is hoping its firms may win some of those contracts.

Some British companies have run into problems in the past. Mobile phone operator Vodafone has repeatedly clashed with the Indian authorities over taxes and oil company Royal Dutch/Shell has asked the British government to raise a tax dispute it has with India during Cameron's visit.

Cameron's aim is to double trade between the two nations from 11.5 billion pounds in 2010, when he last visited, to 23 billion pounds in 2015. Officials say that goal remains on track.

He is expected to meet Manmohan Singh, his Indian counterpart, as well as President Pranab Mukherjee, and to announce a clutch of deals, including cooperation agreements to help India develop its city metro systems.

His office said those deals would create 500 British jobs and safeguard a further 2,000. British firms were also winning contracts in India, it said, saying the Intercontinental Hotel Group planned to build 13 new hotels in the next few years.

Another big trade mission in 2010 failed to yield the gains Cameron had hoped for.

UN warns risk of hepatitis E in S. Sudan grows


GENEVA (AP) — The United Nations says an outbreak of hepatitis E has killed 111 refugees in camps in South Sudan since July, and has become endemic in the region.


U.N. refugee agency spokesman Adrian Edwards says the influx of people to the camps from neighboring Sudan is believed to be one of the factors in the rapid spread of the contagious, life-threatening inflammatory viral disease of the liver.


Edwards said Friday that the camps have been hit by 6,017 cases of hepatitis E, which is spread through contaminated food and water.


He says the largest number of cases and suspected cases is in the Yusuf Batil camp in Upper Nile state, which houses 37,229 refugees fleeing fighting between rebels and the Sudanese government.

Bomb kills 64 in Pakistan's Quetta


QUETTA, Pakistan (Reuters) - Sixty-four people including school children died on Saturday in a bomb attack carried out by extremists from Pakistan's Sunni Muslim majority, police said.


A spokesman for Lashkar-e-Jhangvi, a Sunni group, claimed responsibility for the bomb in Quetta, which caused casualties in the town's main bazaar, a school and a computer center. Police said most of the victims were Shi'ites.


Burned school bags and books were strewn around.


"The explosion was caused by an improvised explosive device fitted to a motorcycle," said Wazir Khan Nasir, deputy inspector general of police in Quetta.


"This is a continuation of terrorism against Shi'ites."


"I saw many bodies of women and children," said an eyewitness at a hospital. "At least a dozen people were burned to death by the blast."


Most Western intelligence agencies have regarded the Pakistani Taliban and al Qaeda as the gravest threat to nuclear-armed Pakistan, a strategic U.S. ally.


But Pakistani law enforcement officials say Lashkar-e-Jhangvi has become a formidable force.


TENSIONS


Last month the group said it carried out a bombing in Quetta that killed nearly 100 people, one of Pakistan's worst sectarian attacks. Thousands of Shi'ites protested in several cities after that attack.


Pakistani intelligence officials say extremist groups, led by Lashkar-e-Jhangvi, have escalated their bombings and shootings of Shi'ites to trigger violence that would pave the way for a Sunni theocracy in U.S.-allied Pakistan.


More than 400 Shi'ites were killed in Pakistan last year, many by hitmen or bombs, and the perpetrators are almost never caught. Some hardline Shi'ite groups have hit back by killing Sunni clerics.


The growing sectarian violence has hurt the credibility of the government, which has already faced criticism ahead of elections due in May for its inability to tackle corruption and economic stagnation.


The schism between Sunnis and Shi'ites developed after the Prophet Muhammad died in 632 when his followers could not agree on a successor.


Emotions over the issue are highly potent even today, pushing some countries, including Iraq five years ago, to the brink of civil war.


Pakistan is nowhere near that stage but officials worry that Sunni extremist groups have succeeded in dramatically ratcheting up tensions and provoking revenge attacks in their bid to destabilize the country.

Aviation industry dons 'shark skins' to save fuel






FRANKFURT: In its never-ending quest to develop more aerodynamic, more fuel-efficient aircraft, the aviation industry believes the ocean's oldest predator, the shark, could hold the key to cutting energy consumption.

Germany's biggest airline Lufthansa announced earlier this month that two of its Airbus A340-300 jets would take part in trials starting this summer to test the properties of shark skin in flight.

For the two-year trials, eight 10 by 10 centimetre (4 by 4 inch) patches of a new type of coating are being painted on to the fuselage and wing edges of the aircraft.

A new state-of-the-art varnish, developed by the Fraunhofer Institute for Manufacturing Technology and Advanced Materials (FAM) in Bremen, attempts to mimic the skins of fast-swimming sharks.

The skin of sharks is covered in tiny riblets that reduce turbulent vortices and the drag they cause, thereby diminishing surface resistance when moving at speed.

The phenomenon of the streamlined shark skin has been known for about 30 years and has fascinated research scientists in a wide range of fields, from military applications to aerospace and aeronautics and from naval construction to wind technology.

More recently, its use in sports such as swimming and athletics has brought the special properties of shark skin to much wider attention.

High-tech swimsuits were developed that enabled athletes to move ever faster through water, breaking one swimming record after the next until the suits were eventually banned as unfair in competition.

In the past, says Volkmar Stenzel, the project's head at the Fraunhofer Institute, sheets of plastic imitation shark skin were glued to the aircraft's exterior.

"But the foil had major disadvantages: it was rather heavy and the added weight cancelled out the amount of fuel that could be saved," Stenzel said.

"Also, it was difficult to stick the foil to curved surfaces without creasing and wrinkling," he said.

Another problem was that aircraft have to be stripped of their paint and recoated every five years "and that was just not possible with these foils," the expert explained.

Thus, in collaboration with European aircraft maker Airbus and the DLR German Aerospace Center, scientists at the Fraunhofer Institute have developed a new technique to emboss the structures of shark skin into aircraft paints.

The idea is to make surfaces more aerodynamic and reduce fuel consumption by about one percent and lower operating costs.

The trials on Lufthansa jets represent the last phase before possible industrial application, said Denis Darracq, head of research and flight physics technology at Airbus.

"The expected results have been achieved in terms of performance. It's now a matter of measuring operational efficiency and durability," Darracq said.

"An airline must not have to clean its aircraft after every flight. The paint needs to last for several years," he said.

The engineer estimated that if an aircraft was covered by between 40-70 percent in the new paint, it can cut fuel consumption by around one percent for very little outlay.

And with high fuel prices and customers becoming increasingly sensitive to the environmental impact of flying, that would represent an "enormous benefit" for an airline, Darracq argued.

Nature is also the inspiration for another state-of-the-art technology that is already being used by the industry and may have wider applications.

The leaf of the lotus plant has a unique microstructure consisting of tiny bumps topped with tiny hairs that make the leaf highly water repellent.

Special surface coatings have been developed to mimic this effect and they are already used in the interior of the A380 to make it easier to clean.

But Airbus is also looking into whether such coatings can be used on the exterior of aircraft as well.

"De-icing is a real problem for planes and represents a substantial cost factor. If there were surfaces where water cannot collect, they wouldn't freeze over and that would represent a big step forward," said Darracq.

Airlines' growing interest could therefore help accelerate research in surface technologies "and these may be ready for industrial application in a number of years," the engineer said.

Malik aimed to boost his relevance at home, Pak?

NEW DELHI: The Indian security agencies suspect that JKLF chief Yasin Malik may have secretly met 26/11 mastermind Hafiz Saeed during his stay in Pakistan, apart from sharing the dais with him at a protest in Islamabad. Even as his alleged one-on-one meeting with the LeT boss is kept carefully under wraps, Malik, intelligence officials say, ensured a photo opportunity alongside Saeed to "score" over moderate Hurriyat's "secret" meeting with him last December.

Till now sidelined in Kashmir's separatist politics and desperate to win over the support of Pakistani agencies, Malik possibly saw his appearance with Saeed as a last-ditch bid to boost his relevance at home and across the border.

The intelligence agencies have already rejected Malik's defence that his sharing the stage with Saeed was co-incidental. "I was on a hunger strike for 24 hours near Islamabad Press Club. Thousands of people came there including Hafiz Saeed, who came there for 15 minutes...where did the meeting take place?" the JKLF leader had argued after his public appearance with Saeed sparked an outrage here.

Agencies, however, feel Malik's photo-opportunity with the LeT boss was intentional. "It is virtually impossible for Malik to not have known the list of big leaders who he would be sharing the stage with, particularly those with a profile as daunting as Saeed's," an official pointed out.

"Considering the interest generated by moderate Hurriyat leaders' 'secret' meeting with Saeed in December, Malik possibly thought that a public appearance with the LeT founder in Islamabad would help him score over them. His real meeting with Saeed, however, may have happened away from the public eye to ensure deniability," the official added.

Saeed's active interest in Kashmir is public knowledge. In fact, at a recent rally in Lahore to mark the Kashmir solidarity day, the LeT founder and Jamaat ud Dawah boss urged India to "leave Kashmir", warning that Indian Army would be defeated and Kashmir would get independence. He pledged support to all Kashmiri leaders and hoped for their unity.

According to an intelligence assessment, Malik, who has lately been overshadowed by Kashmiri separatist leaders of the Tehreek-e-Hurriyat like hardliner Syed Ali Shah Geelani and the moderate Hurriyat under Mirwaiz Umer Farooq, may have sensed an opportunity to bounce back to the centrestage just by being seen with Saeed. His fast in Islamabad against the hanging of Afzal Guru provided him the right setting to pull off the photo-opportunity.

Intelligence officials point out that just like leaders of the two Hurriyat factions, which are dependent on ideological and logistical support from Pakistan to further their campaign in the Valley, the JKLF leader too has shed his hardened pro-azaadi stand and is looking for support from across the border.

Though Malik may be questioned upon his return from Pakistan on his "encounter" with Saeed, the agencies believe there the Centre can do little beyond either revoking his passport or denying its extension beyond March 31, when it is due to expire anyway. "Arresting him will only help him play the victim," an official has warned.
