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."

Pistorius Case: Agent Cancels All Future Races

Oscar Pistorius won't run in any of the future races that the athlete was contracted to compete in, but the Paraylmpic gold medalist's sponsors are still supportive as he faces a murder charge, his agent said today.

The decision to cancel Pistorius' scheduled appearances was made to "allow Oscar to concentrate on the upcoming legal proceedings and to help and support all those involved as they try to come to terms with this very difficult and distressing situation," Peet Van Zyl of In Site Athlete Management said in a statement.

"I have decided that following these tragic events that we have no option but to cancel all future races that Oscar Pistorius had been contracted to compete in," Van Zyl said.

Pistorius was slated to compete in races in Australia and Brazil, as well as at the Drake Relays in Iowa and the Manchester City Games in the U.K.

Van Zyl also said that Pistorius' sponsors and partners are supportive.

"I can confirm that at this point in time, all parties are supportive and their contractual commitments are maintained. They have said they are happy to let the legal process takes its course before making any change in their position," Van Zyl said in the statement.

However, M-Net movies, a subscription-funded South African television channel has pulled their ad campaign featuring Pistorius, tweeting, "Out of respect & sympathy to the bereaved, M-Net will be pulling its entire Oscar campaign featuring Oscar Pistorius with immediate effect."

The agent's announcement comes as family and friends rallied to Pistorius' defense -- saying they believe the Paralympic gold medalist's story that he shot his model girlfriend Reeva Steenkamp by accident after he mistook her for an intruder.

"When you are a sportsman, you act even more on instinct ... it's instinct -- things happen and that's what you do," Pistorius' father Henke Pistorius, 59, told The Telegraph.

The 26-year-old athlete, known as the "Blade Runner" because of the carbon-fiber blades he runs on, was charged Friday with premeditated murder.

If convicted, Pistorius could face at least 25 years in jail.

"All of us saw at firsthand how close [Steenkamp] had become to Oscar during that time and how happy they were. They had plans together and Oscar was happier in his private life than he had been for a long time," Pistorius' uncle Arnold Pistorius said on Saturday.

According to South African newspaper Beeld, Steenkamp was killed nearly two hours after police were called to Pistorius' home to respond to reports of an argument at the complex.

Police said they have responded to disputes at the sprinter's residence before, but did not say whether Steenkamp was involved.

The athlete's best friend said Pistorius called him after the shooting to say "there has been a terrible accident, I shot Reeva," Justin Divaris told the Sunday People.

While his family insists he is not a murderer, prosecutors disagree.

Police sources told local media that Steenkamp was shot through the bathroom door where she may have been trying to hide to save herself.

Reeva Steenkamp

A memorial service for Steenkamp will be held in Port Elizabeth on Tuesday evening, SABC reported. Her body will be flown back for the service before being cremated, her family said.

"Her future has been cut short ... I dare say she's with the angels," said Mike Steenkamp, Reeva Steenkamp's uncle.

The South African reality show Steenkamp competed in premiered Saturday night on SABC as planned and included a special tribute to the slain law school graduate whose modeling career was starting to take off.

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.

Correa won 58 percent of the votes compared with 24 percent for runner-up Guillermo Lasso, according to preliminary results released by the electoral authority based on almost 30 percent of the votes counted.

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

"We are making history, we are building our own homeland which is Ecuador and the great homeland which is Latin America."

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.

"He has breathed new life into the country with the infrastructure and social programs. He has allowed the country to recover its dignity," said Rosa Patino, 40, a municipal worker in Quito.

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 many off.

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 high 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.

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 on attacking Correa and failed to put forward concrete proposals to entice voters.

Ecuadoreans also chose a new Congress on Sunday.

The ruling 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.

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.

Could 9-year-old win youngest best actress Oscar?

LOS ANGELES: She landed the part by lying about her age: Quvenzhane Wallis was five, and the filmmakers were only auditioning girls at least six years old.

But they believed her fib and tried her out -- and were blown away, giving her the starring role in the low-budget "Beasts of the Southern Wild" over 4,000 other hopefuls.

And now she could become the youngest ever winner of the best actress Oscar, at the 85th Academy Awards, the climax of Hollywood's annual awards season, next weekend.

"It was very clear ...you don't meet six-year-olds who have that quality," said director Benh Zeitlin, recalling her audition. "She just had this natural charisma and focus and fierceness and wiseness and morality.

"Coming out of a body that small and a mind that young, it's almost alien and alien in a way that goes kind of straight at your heart .. It's her perspective that unlocks the truth in the film."

That charisma is obvious when you see Wallis being interviewed to promote the movie over recent months, even before it was elevated to the stratosphere by being nominated for four Oscars in January, including best picture.

"I was in my bedroom half asleep," Wallis told Jay Leno, about waking last month to learn she was nominated alongside Jessica Chastain, Jennifer Lawrence, Naomi Watts and Emmanuelle Riva, the oldest ever best actress nominee, at 85.

"So nothing reacted on the outside, but I was like flipping cartwheels and stuff on the inside," she told the talk show host, whom she admonished -- cutely -- for asking her a question more appropriate for the director.

In the movie Wallis plays Hushpuppy, living in the Louisiana bayou with her hot-tempered and ailing father Wink, in a community threatened by floods driven by melting ice-caps.

"Beasts of the Southern Wild" won the prestigious Camera d'Or at last year's Cannes Film Festival in France, and the Grand Jury Prize for a dramatic film at Sundance.

The movie's setting was close to Wallis' home: the actress -- her first name is pronounced Qua-ven-zhah-nay -- was born in Houma, Louisiana, on August 28, 2003. The "zhane" part of her name means fairy in Swahili.

"Beasts" was her first acting job, and she only got it after ignoring the filmmaker's audition rules -- perhaps, appropriately, like the character she was asked to play.

"It was for a six-to-nine-year-old. So my Mom said I couldn't go 'cause I was only five. But we just went and we act like we're having nothin' to do; we had done nothin' wrong," she said.

"The character who is Hushpuppy, she does what is right and she is fearless and that's what I did at the audition."

Wallis is the youngest best actress Oscar nominee by four years: the next is Keisha Castle-Hughes, who was 13 when nominated for "Whale Rider" in 2003. The third, Lawrence, nominated again this year, was first tapped in 2010 at age 20 for "Winter's Bone".

The youngest ever best actress Oscar winner is Marlee Matlin, who took the prize in 1986 for "Children of a Lesser God" at the positively mature age of 21 years and 218 days.

The youngest person to ever win an Oscar in any competitive category is Tatum O'Neal, who was just 10 when she took home the best supporting actress prize in 1973.

Wallis is already on her third film -- "Twelve Years a Slave," with Brad Pitt, Benedict Cumberbatch and Michael Fassbender, due out in September. She has also made "Boneshaker," a short about an African family lost in America.

Whether she wins an Oscar on Sunday or not -- the favorites are Chastain and Lawrence, admittedly -- she is clearly a force to be reckoned with, and an actress to watch out for in years to come.

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.

Meteor Blast 'Something We Only Saw in Movies'

A day after a massive meteor exploded over this city in central Russia, a monumental cleanup effort is under way.

Authorities have deployed around 24,000 troops and emergencies responders to help in the effort.

Officials say more than a million square feet of windows -- the size of about 20 football fields -- were shattered by the shockwave from the meteor's blast. Around 4,000 buildings in the area were damaged.

The injury toll climbed steadily on Friday. Authorities said today it now stands at more than 1,200. Most of those injuries were from broken glass, and only a few hundred required hospitalization.

According to NASA, this was the biggest meteor to hit Earth in more than a century. Preliminary figures suggest it was 50 feet wide and weighed more than the Eiffel Tower.

SEE PHOTOS: Meteorite Crashes in Russia

NASA scientists have also estimated the force of the blast that occurred when the meteor fractured upon entering Earth's atmosphere was approximately 470 kilotons -- the equivalent of about 30 Hiroshima bombs.

Residents said today they still can't believe it happened here.

"It was something we only saw in the movies," one university student said. "We never thought we would see it ourselves."

Throughout the city, the streets are littered with broken glass. Local officials have announced an ambitious pledge to replace all the broken windows within a week. In the early morning hours, however, workers could still be heard drilling new windows into place.

Authorities have sent divers into a frozen lake outside the city, where a large chunk of the meteor is believed to have landed, creating a large hole in the ice. By the end of the day they had not found anything.

They are not the only ones looking for it.

Meteor hunters from around the world are salivating at what some are calling the opportunity of a lifetime. A small piece of the meteor could fetch thousands of dollars and larger chunks could bring in even hundreds of thousands.

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.

"Argo", "Lincoln" vie for Oscars crown in open race

LOS ANGELES - Steven Spielberg goes into next weekend's Oscars with the most nominations for his presidential "Lincoln" but the momentum is all with Ben Affleck's thriller "Argo" in the Academy Awards home straight.

And while the Hollywood veteran and the young pretender vie for the Oscars best picture crown, several other frontrunners remain hard on their heels, in one of the least predictable Oscar races in recent memory.

Taiwan-born Lee Ang's 3D spectacular "Life of Pi," Osama bin Laden manhunt movie "Zero Dark Thirty" and romcom "Silver Linings Playbook" could all be in with a chance at the Oscars, the climax of Tinseltown's annual awards season.

Spielberg and Lee are frontrunners for best director, while "Lincoln" star Daniel Day-Lewis is widely seen as a shoo-in for best actor. For best actress the hot money is on Jessica Chastain for her part in "Zero Dark Thirty" or "Hunger Games" star Jennifer Lawrence.

But Affleck's Iran hostage drama, despite only winning seven nominations -- against 12 for "Lincoln," 11 for "Life of Pi" and eight each for "Silver Linings Playbook" and "Les Miserables" -- has a clear edge for best picture.

It has swept up top prizes at a string of key awards shows, including the Golden Globes, the Screen Actors Guild (SAG), Producers Guild of America (PGA), the Directors Guild of America (DGA), and Britain's BAFTA last weekend.

Affleck has gotten used to making acceptance speeches over the last two months -- but he has been tightlipped on his prospects for the all-important 85th Academy Awards, to be held at Hollywood's Dolby Theatre next Sunday.

"I just feel so incredibly honoured to be nominated as a producer for this movie. To be here at the big party," he said at the Oscar Nominees Luncheon, the annual gathering of those in the race, held in Beverly Hills on February 4.

Indeed, his best picture nomination is as a co-producer of the film -- along with George Clooney and Grant Heslov -- rather than as a director, a category in which he was not nominated, in a perceived snub.

Snub or no snub, he will be among presenters at the show, along with a Who's Who of A-listers including Halle Berry, Sandra Bullock, Nicole Kidman, Reese Witherspoon, Robert Downey Jr, Samuel L Jackson, and Meryl Streep.

"Family Guy" creator Seth MacFarlane will be hosting, a move organizers hope will attract younger viewers among the hundreds of millions watching live around the world.

Other nominees presenting include Chastain -- best actress frontrunner for playing a relentless CIA agent on the hunt for Osama, in Oscar-winning director Kathryn Bigelow's controversial "Zero Dark Thirty".

But Lawrence, star of the "Hunger Games" blockbuster franchise, could also win the category for her portrayal of mixed-up Tiffany to Bradley Cooper's bipolar ex-teacher in "Silver Linings Playbook".

Cooper is up for best actor, along with Hugh Jackman for "Les Miserables", Joaquin Phoenix for "The Master" and Denzel Washington for "Flight" -- but Day-Lewis is widely forecast for a record third Oscar for his "Lincoln" turn.

For best director, 66-year-old Spielberg will be hoping for his first Oscar since "Saving Private Ryan" in 1999.

But he is up against Lee -- whose "Brokeback Mountain" won best picture in 2006 -- as well as Michael Haneke for his Cannes-winning "Amour", David O Russell for "Silver Linings Playbook" and Benh Zeitlin for "Beasts of the Southern Wild".

Best supporting actor nominees are Alan Arkin for "Argo", Robert De Niro for "Silver Linings Playbook", Philip Seymour Hoffman for "The Master", Tommy Lee Jones for "Lincoln" and Christoph Waltz for "Django Unchained".

For supporting actress Anne Hathaway is tipped to win for performance in "Les Miserables" -- including her heart-wrenching close-up rendition of "I Dreamed a Dream" -- against Amy Adams for "The Master", Sally Field in "Lincoln", Helen Hunt in "The Sessions" and Jacki Weaver in "Silver Linings Playbook".

The Oscars have a musical theme this year, including a performance by Britain's Adele singing the Oscar-nominated 007 theme tune "Skyfall" as well as by Shirley Bassey and Norah Jones, and Barbra Streisand, in her first Oscars turn since 1977.
