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.

Chavez back in Venezuela, on Twitter with four million followers


CARACAS (Reuters) - After Hugo Chavez spent two months out of the public eye for cancer surgery in Cuba, the Venezuelan government hailed his homecoming on Monday and said the president had achieved another milestone - 4 million followers on Twitter.


The 58-year-old flew back from Havana before dawn and was taken to a military hospital. No new details were given on his health, and there were no images of his arrival. Officials say his condition remains delicate.


The normally loquacious socialist leader, who is struggling to speak as he breathes through a tracheal tube, took to Twitter with a passion back in April 2010, tweeting regularly and encouraging other leftist Latin American leaders to do likewise.


His @chavezcandanga account quickly drew a big mixed following of fans, critics and others just curious to see how his famously long speeches and fiery anti-U.S. invective would work within the social media network's 140-character limit.


But as he fought the cancer and underwent weeks of grueling chemotherapy and radiation therapy, he began to tweet less and less frequently, before stopping altogether on November 1.


Early on Monday morning, he made his reappearance.


"It was 4:30, 5 a.m. He got to his room and surprised everyone: rat-tat-tat, he sent three or four messages, and at that moment fireworks began to go off around the country," Vice President Nicolas Maduro said in a televised cabinet meeting.


During the day, Maduro added, the president's number of followers had shot up to well over four million.


"It's incredible, in just a few hours ... he's the second most-followed president in the world (after Barack Obama), and the first if we make the comparison by per capita," he said.


Obama has more than 27 million Twitter followers and is No. 5 most followed globally. Chavez is Twitter's No. 190 globally.


4TH MILLION FOLLOWER


Maduro said Chavez's four millionth follower was a 20-year-old single Venezuelan woman named Alemar Jimenez from the gritty San Juan neighborhood in downtown Caracas, near the military hospital where the president arrived earlier in the day.


"She's one of the golden generation of youth who support the fatherland and have been waiting with growing love for commander Hugo Chavez," Maduro said, before presenting a dazzled-looking Jimenez to the cameras and giving her a bunch of flowers.


"We were really emotional" she said, recounting how she was with her mother when they heard Chavez had returned. "I sent him a message on Twitter saying he must get better."


There are still big questions over the president's health. He could have come back to govern from behind the scenes, or he may be hoping to ease political tensions and pave the way for a transition to Maduro, his preferred successor.


Chavez has often ordered followers to fight back against opposition critics of his self-styled revolution by using social media, leading from the front himself on Twitter and referring to the Internet as a "battle trench."


As his ranks of followers grew, Chavez said he hired 200 assistants to help him respond to messages - which he said were a great way to receive first-hand the requests, demands, complaints and denunciations of citizens in the thousands.


During his re-election campaign last year, the government launched an SMS text message service that forwards his tweets to cellphones that lack Internet service, broadening their reach to the poorest corners of the South American country.


"He's a communication revolution!" Maduro said, later unbuttoning his shirt on TV to show he was wearing a T-shirt bearing Chavez's eyes emblazoned across his chest.


For the tens of thousands who signed up on Monday to follow Chavez on Twitter, it is unclear how much will be posted there in the weeks and months ahead. Venezuela's 29 million people are mostly wondering something similar.

Australian opposition leaps ahead in polls






SYDNEY: Australia's opposition coalition has increased its lead as support for Prime Minister Julia Gillard and her Labor Party wanes ahead of September elections, according to a poll.

The Herald-Nielsen poll for Fairfax newspapers found the opposition would win 55 percent of the vote, against 45 percent for the Labor-led government.

As a single party, without minority backers, Labor would win just 30 percent of first preference votes -- a fall of five points since the last Nielsen survey in December.

The coalition climbed four points by the same measure, taking its primary vote to 47 percent.

Opposition leader Tony Abbott overtook Gillard in the preferred prime minister stakes, surging nine points to 49 percent while the prime minister dropped five points to 45 percent.

Gillard sought to downplay the figures, which suggest that her gamble in announcing the election nearly eight months before polling day was not well received by voters.

"We see a lot of opinion polls," Gillard told Seven Network television.

"If I spent time worrying about them and commentating on opinion polls then I wouldn't have the time to get my job done.

"So each and every day I just let that wash through and I focus on what I need to do as prime minister."

Gillard broke with tradition by fixing the September 14 election date well ahead of time, hoping to force the opposition to detail its policies and costings.

However Labor's retreat from a much-vaunted promise to restore the budget to surplus this year, the failure of a controversial mining tax to raise much revenue and corruption scandals have dominated headlines.

The prime minister's approval ratings plunged six points to 40 percent and her disapproval level rose six to 56 percent.

The national poll of 1,400 voters, taken from Thursday to Saturday, found the gap between Gillard and former Labor prime minister Kevin Rudd had widened.

Sixty-one percent of respondents favoured Rudd against 35 percent for Gillard. Despite his protests to the contrary, speculation is rife of another Rudd tilt at the Labor leadership either before the polls or after election defeat.

Rudd was deposed by Gillard, then his deputy, in a shock party-room ouster before the 2010 elections. He mounted a challenge last February but lost 71-31 in a secret leadership ballot.

Nielsen pollster John Stirton told the Sydney Morning Herald the results were a bad sign for Labor.

"It confirms that the trend to Labor that ran from May to November last year and appeared to stall over Christmas is now heading in the opposite direction."

British PM David Cameron arrives in Mumbai on three-day India visit

MUMBAI: British Prime Minister David Cameron arrived here on Monday morning on a three-day India visit during which will he meet captains of industry and hold talks with top leaders who are likely to seek more information on the VVIP helicopters scam involving an Anglo-Italian firm.

Cameron is likely to be pressed for more information on the Rs 3,600 crore helicopter scam involving AgustaWestland during his meetings with the leadership on Tuesday. The helicopters, three of which have already been delivered, were manufactured in southwest England.

The visit also comes in the wake of India taking steps to scrap the contract after Italian investigators probed allegations that aerospace group Finmeccanica, the parent company of AgustaWestland, had broken the law by paying bribes to foreign officials.

Cameron landed here at around 8.30am and was received at the airport by minister of protocol Suresh Shetty and senior Maharashtra government officials.

He is accompanied by a large delegation which includes CEO of top British corporates, vice-chancellors of reputed universities and senior Government officials, among others.

"In Mumbai, Cameron's programmes include visit to Hindustan Unilever headquarters, a luncheon meeting with business leaders, a visit to St Xavier's School and laying a wreath at the Police Memorial," an MEA statement said.

The premier will leave for New Delhi in the evening. Cameron is also expected to attend a private function being hosted by a large conglomerate before leaving for the national capital, according to industry sources.

This would be his second visit to the country since he took over the mantle, with the first being soon after assuming office in May 2010.

In Delhi, Cameron will hold comprehensive talks with Prime Minister Manmohan Singh on a wide range of bilateral, regional and international issues.

Besides the defence deal, other major issues expected to figure during Cameron's visit would include the Rs 12,000- crore Vodafone tax matter and the UK hosting a meeting between the Pakistan and Afghanistan presidents.

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.

Troubled Country Singer Shot Herself, Cops Say











Mindy McCready, the country singer who soared to the top of the charts with her debut album, "Ten Thousand Angels," but struggled with substance abuse, served time in jail and fought a lengthy battle with her mother over custody of her son has died of what appears to be a self-inflicted gunshot wound, police said. She was 37.


Deputies from the Cleburne County Sheriff's Office were dispatched to a report of gun shots fired at McCready's Heber Springs, Ark., home at around 3:30 p.m. today.


There they found McCready on the front porch. She was pronounced dead at the scene from what appeared to be a single self-inflicted gunshot wound, according to a statement from the sheriff's office.


McCready's boyfriend, David Wilson, died in January of a self-inflicted gunshot wound. McCready was ordered to enter rehab shortly after Wilson's death, and her two children, Zander, 6, and 9-month-old Zayne were taken from her. She was released after one day to undergo outpatient care.


McCready scored a number-one Billboard country hit in 1996 with "Guys Do It All the Time," but in recent years, the country crooner has received more media attention for her troubled personal life than her music.


She has been arrested multiple times on drug charges and probation violations and has been hospitalized for overdoses several times, including in 2010, when she was found unconscious at her mother's home after taking a painkiller and muscle relaxant.

Her mother, Gayle Inge, was appointed to be her son Zander's legal guardian in 2007 after McCready was arrested for violating probation on a drug-related charge. The boy's father is McCready's ex-boyfriend Billy McKnight.


Following a custody hearing in May 2011, McCready released a statement, saying, "We have progressed in a positive manner to reunite me and my son, Zander. I feel very optimistic this will happen in the near future."


But just six months later, in November 2011, was accused of violating a court order for failing to bring Zander back to her mother in Florida after a visit. The boy was placed in foster care while McCready and her mother worked out the custody dispute.


McCready's struggle with substance abuse was broadcast in 2010 on the third season of "Celebrity Rehab with Dr. Drew."


McCready also claimed to have carried on a decade-long affair with baseball star Roger Clemens that began was she was 15 years old and he was 28. Clemens denied that the relationship was sexual in nature.


"You know what, I don't think I'm ever going to be one of those people that has a normal, quiet existence," McCready told ABC Radio in 2010. "I've been chosen for some reason to be bigger and larger than life in every way. Negative and positive."


McCready, who was born and raised in southern Florida, moved to Nashville when she was 18 to start her music career.


Within a few months, she was starting to work with producer David Malloy, who got her tapes to RLG Records. The company signed her to a contract after seeing her in concert, giving her a record deal less than a year after her arrival in Nashville.


Her debut album, "Ten Thousand Angels," went gold within six months of its release in April 1996, and eventually went multi-platinum. Two more followed: "If I Don't Stay the Night," in 1997; and "I'm Not So Tough" in 1999.


Her most recent album, "I'm Still Here," featuring new versions of her early hits "Ten Thousand Angels" and "Guys Do It All the Time," was released in March 2010.

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.

Australia seeks answers from Israel on 'Prisoner X'






SYDNEY: Canberra said Sunday it was seeking answers from Israel over the death in 2010 of an Australian known as "Prisoner X" in a Tel Aviv jail as part of its own probe into the case.

Foreign Minister Bob Carr said his office was preparing a formal report into the circumstances surrounding the death of the prisoner, identified in Australian media as Ben Zygier, 34, who Israel says committed suicide.

That the detainee, held in a high security prison under continuous surveillance, managed to hang himself has raised questions and fed conspiracy theories that have been reported by the Israeli and Australian media.

Many questions remain unanswered in the mysterious case, with a senior unnamed Israeli official telling The Australian newspaper that Australian officials had interrogated the prisoner on suspicion of spying for Mossad.

Carr said foreign office chief Peter Varghese was preparing a report which would "canvass all the consular contact between Australia and between Israel" including contact between security agencies.

"We have asked the Israeli government for a contribution to that report," Carr told reporters in Sydney.

"We want to give them an opportunity to submit to us an explanation of how this tragic death came about."

If the report showed "any areas where we can improve our contact in consular cases like this", Carr said, "it will have practical effect when there are cases in the future where an Australian citizen is treated in a comparable way."

"I need to know what the contact was between Australian agencies and those of Israel, and I need to see what the Israelis want to tell Australia," he said. "The key is to get all the information."

Carr, foreign minister since early 2012, originally said the Australian government had not been informed of the prisoner's plight.

He later backtracked on this claim, conceding that Canberra was told in February 2010 -- 10 months before the death -- that Israel had detained an Australian-Israeli citizen on national security grounds.

Carr's predecessor Kevin Rudd, foreign minister at the time of the prisoner's death, said Sunday it was important that Australia "get to the bottom of this".

"(I was) deeply surprised to hear not only had this person been incarcerated, but subsequently died in custody," Rudd told Sky News.

"The tradition of this government has to be robust on these matters, even with a country with whom we've had the friendliest of relationships."
