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."

European shares edge higher, euro flat ahead German data

LONDON (Reuters) - European shares edged higher and the euro was steady on Tuesday ahead of German economic sentiment data, while the yen rose after Japanese ministers played down talk the Bank of Japan might buy foreign bonds to loosen credit.

Following last week's GDP figures showing that the euro zone saw a weaker end to 2012 than expected, forecasters see a pick-up in Germany's ZEW survey of investors and analysts at 1000 GMT, which may point to rebound in the bloc's biggest economy.

European stock markets, which have lost around 1.5 percent since the end of January, bounced backed from Monday's weak session in early trading, with the FTSEurofirst 300 <.fteu3> up 0.4 percent led by 0.7 and 0.5 percent gains on Paris's CAC-40 <.fchi> and Frankfurt's DAX <.gdaxi>.

Underscoring the drag Europe's economic sluggishness is creating, new figures showed car firms had their weakest January since the records of the Association of European Carmakers began in 1990, with sales dropping 8.5 percent.

Berkeley Futures associate director Richard Griffiths said the Euro STOXX 50 and German DAX <.gdaxi> equity index could fall by between 3 and 4 percent over the coming month as economic weakness acts to cap investor sentiment.

"Any inroads to the upside will be hard to come by," he said. "We're in for a period of consolidation, with the risk more to the downside."

In the bond market, benchmark German Bunds edged up as demand for low-risk debt was also supported by concerns over the possibility of an inconclusive outcome to the Italian parliamentary election on Sunday and Monday, though gains were capped ahead of the German sentiment data.

The euro was little changed against the dollar at $1.3345 by 0900 GMT after European Central Bank President Mario Draghi reiterated on Monday that the bank would continue to monitor whether the currency's recent strength was likely to push inflation below its comfort zone.

The yen rose after Japanese ministers played down talk of foreign-bond buying by the country's central bank, a day after Prime Minister Shinzo Abe said such a policy could be one option for monetary easing.

Finance Minister Taro Aso told a news conference that he was not considering foreign-bond purchases as a part of monetary easing, while Economy Minister Akira Amari said Abe's comments on Monday simply referred to policy options countries have in general.

Their comments sent the dollar down to 93.39 yen. The euro eased 0.6 percent to 124.70 yen, well below its peak since April 2010 of 127.71 yen touched on February 6.

U.N. says has list of Syrian war crimes suspects

GENEVA (Reuters) - Syrians in "leadership positions" who may be responsible for war crimes have been identified, along with units accused of perpetrating them, United Nations investigators said on Monday.

Both government forces and armed rebels are committing war crimes, including killings and torture, spreading terror among civilians in a nearly two-year-old conflict, they said.

The investigators' latest report, covering the six months to mid-January, was based on 445 interviews conducted abroad with victims and witnesses, as they have not been allowed into Syria.

The independent team, led by Brazilian Paulo Pinheiro, called on the U.N. Security Council to "act urgently to ensure accountability" for grave violations, possibly by referring the violators to the International Criminal Court for prosecution.

"The ICC is the appropriate institution for the fight against impunity in Syria. As an established, broadly supported structure, it could immediately initiate investigations against authors of serious crimes in Syria," the 131-page report said.

It added: "Individuals may also bear criminal responsibility for perpetuating the crimes identified in the present report. Where possible, individuals in leadership positions who may be responsible were identified alongside those who physically carried out the acts."

Karen Konig AbuZayd, one of the four commissioners on the team of some two dozen experts, told Reuters: "We have information suggesting people who have given instructions and are responsible for government policy. People who are in the leadership of the military, for example."

"It is the first time we have mentioned the ICC directly. The Security Council needs to come together and decide whether or not to refer the case to the ICC. I am not optimistic."

But its third list of suspects, building on lists drawn up in the past year, remains secret. It will be entrusted to U.N. High Commissioner for Human Rights, Navi Pillay, upon expiry of its current mandate at the end of March, the report said.

Pillay, a former judge at the ICC, said on Saturday that Syrian President Bashar al-Assad should be probed for war crimes and called for immediate action by the international community, including possible military intervention.

"The evidence collected sits in the safe in the office of the High Commissioner against the day it might be referred to a court and evidence would be examined by a prosecutor," said a European diplomat.

The death toll in Syria is likely approaching 70,000 people, Pillay told the Security Council last week in a fresh appeal for it to refer Syria to the ICC, the Hague-based war crimes court.

Government forces have carried out shelling and aerial bombardment across Syria including Aleppo, Damascus, Deraa, Homs and Idlib, the independent U.N. investigators said, citing corroborating evidence gathered from satellite images.

"In some incidents, such as in the assault on Harak, indiscriminate shelling was followed by ground operations during which government forces perpetrated mass killing," it said, referring to a town in the southern province of Deraa where residents told them that 500 civilians were killed in August.

"SPREADING TERROR"

"Government forces and affiliated militias have committed extra-judicial executions, breaching international human rights law. This conduct also constitutes the war crime of murder. Where murder was committed as part of a widespread or systematic attack against a civilian population, with knowledge of that attack, it is a crime against humanity," the U.N. report said.

They have targeted queues at bakeries and funeral processions, in violence aimed at "spreading terror among the civilian population", it said.

"Syrian armed forces have implemented a strategy that uses shelling and sniper fire to kill, maim, wound and terrorize the civilian inhabitants of areas that have fallen under anti-government armed group control," the report said.

Government forces had used cluster bombs, it said, but it found no credible evidence of either side using chemical arms.

Rebel forces fighting to topple Assad in the protracted and increasingly sectarian conflict have committed war crimes include murder, torture, hostage-taking and using children under age 15 in hostilities, the U.N. report said.

"They continue to endanger the civilian population by positioning military objectives inside civilian areas," it said. Rebel snipers had caused "considerable civilian casualties".

"The violations and abuses committed by anti-government armed groups did not, however, reach the intensity and scale of those committed by government forces and affiliated militia."

Foreign fighters, many of them from Libya, Tunisia, Saudi Arabia, Lebanon, Iraq and Egypt, have radicalized the rebels and helped detonate deadly improvised explosive devices, it said.

The two other commissioners are former chief ICC prosecutor Carla del Ponte and Vitit Muntarbhorn of Thailand.

"It is an investigative mechanism and its evidence can be given to relevant judicial authorities when the time comes. In the interim, it is the one piece of U.N.-approved machinery shining a light on abuses," the European diplomat said.

Referring to del Ponte, who joined in September, the diplomat said: "She brings a harder-edged prosecutorial lens so when they are looking at the evidence she is very well placed to know what sort of evidence would assist a later judicial process."

Downton Abbey's Season 3 Finale: Shocking, Says PEOPLE's TV Critic

Downton Abbey

By Tom Gliatto

02/17/2013 at 10:00 PM EST

Downton Abbey season 3 cast

Carnival Film & Television/PBS

Downton Abbey's third season finale on PBS's Masterpiece was, to say the least, a spoiler's paradise. The episode, which saw the Granthams and servants going on holiday in the Scottish Highlands, started on a joyful note – Lady Mary was pregnant! – and ended with a shock that would have knocked the hat off Lady Violet wobbling head.

SPOLIER ALERT: Major plot points to be revealed immediately.

Cousin Matthew (Dan Stevens) died in a car accident. He was driving back to Downton, so happy he was practically whistling, just after Lady Mary (Michelle Dockery) had given birth to their son – the male Downton heir everyone has been so obsessed with since Season 1.

Many viewers probably saw this coming: For one thing, Stevens had said he was thinking of decamping before season 4 started shooting. And after the finale had its premiere broadcast in Britain in December, he blabbed all about it, including for an interview posted online by The New York Times.

Even so, the death was almost sadistically abrupt and arbitrary, especially after the soft tenderness and growing love between Mary and Matthew in recent episodes. Now we saw dead poor Matthew dumped on the cold mossy ground, eyes wide open.

You can never be sure Downton writer-creator Julian Fellowes won't pull some shameless stunt to kick-start a story – in season 2 Matthew, paralyzed during the war, suddenly leaped out of his wheelchair – but he seemed to want us to be sure that Matthew was 100% gone. I wouldn't have been surprised if the car backed over the corpse.

So ended a terribly sad season of Downton.

We already suffered the loss in childbirth of Lady Sybil (Jessica Brown Findlay). Her deathbed scene was unflinching and deeply moving as she gasped for breath and called for help. Her poor mother (Elizabeth McGovern) sobbed in despair, and the doctors couldn't agree on what to do.

Millions of viewers cried, too, and sighed for a long time afterward. Those who didn't are probably evil.

That scene was the heart of the season: Sybil was so beautiful and kind and gracious and spirited, and so different from her fractious sisters. It was if one were to discover a rare, transcendent soul among the Kardashians. Her death robbed the show of a lovely presence, and also brought out the best moments yet from McGovern and Maggie Smith, as Lady Violet.

It never ceases to annoy me, to be honest, that Lady Violet's feeble witticisms are treated as if they were Oscar Wilde one-liners on loan, like Harry Winston jewels. If you want real witticisms, try any contemporary American sitcom, including FX's Archer.

But this season, as Violet grieved, we saw how much depth Smith can invest in a single moment. At one point in the finale, she looked up as dinner was announced, and in her enormous eyes you saw a woman who wished she could just chuck the whole damn thing and dwell on her memories.

I wish I could say I will miss Matthew, but all in all an unattached Lady Mary is better than a married one. She was never sexier than in the first season, when she sneaked off to bed with velvety, sensual Mr. Pamuk, who unfortunately kicked the bucket while they made love.

Mary is a wonderful creation – the show's most original, complex character – capable of bouncing from romance to sorrow to sarcasm. You could say her love for Matthew transformed her, but it also had the potential to dull her.

Matthew was blandly handsome and good and patient and full of improving notions, but not terribly exciting. He was like a Bachelor from a much earlier period.

There isn't much else to say about the finale. Fellowes worked through a number of plots with his usual tangy glibness. The performances were all delightful, tart, full of emotion, humor and regret.

For now, we can look forward to Lady Mary at her most beautiful, because most woeful, in season 4.

Study: Better TV might improve kids' behavior

SEATTLE (AP) — Teaching parents to switch channels from violent shows to educational TV can improve preschoolers' behavior, even without getting them to watch less, a study found.

The results were modest and faded over time, but may hold promise for finding ways to help young children avoid aggressive, violent behavior, the study authors and other doctors said.

"It's not just about turning off the television. It's about changing the channel. What children watch is as important as how much they watch," said lead author Dr. Dimitri Christakis, a pediatrician and researcher at Seattle Children's Research Institute.

The research was to be published online Monday by the journal Pediatrics.

The study involved 565 Seattle parents, who periodically filled out TV-watching diaries and questionnaires measuring their child's behavior.

Half were coached for six months on getting their 3-to-5-year-old kids to watch shows like "Sesame Street" and "Dora the Explorer" rather than more violent programs like "Power Rangers." The results were compared with kids whose parents who got advice on healthy eating instead.

At six months, children in both groups showed improved behavior, but there was a little bit more improvement in the group that was coached on their TV watching.

By one year, there was no meaningful difference between the two groups overall. Low-income boys appeared to get the most short-term benefit.

"That's important because they are at the greatest risk, both for being perpetrators of aggression in real life, but also being victims of aggression," Christakis said.

The study has some flaws. The parents weren't told the purpose of the study, but the authors concede they probably figured it out and that might have affected the results.

Before the study, the children averaged about 1½ hours of TV, video and computer game watching a day, with violent content making up about a quarter of that time. By the end of the study, that increased by up to 10 minutes. Those in the TV coaching group increased their time with positive shows; the healthy eating group watched more violent TV.

Nancy Jensen, who took part with her now 6-year-old daughter, said the study was a wake-up call.

"I didn't realize how much Elizabeth was watching and how much she was watching on her own," she said.

Jensen said her daughter's behavior improved after making changes, and she continues to control what Elizabeth and her 2-year-old brother, Joe, watch. She also decided to replace most of Elizabeth's TV time with games, art and outdoor fun.

During a recent visit to their Seattle home, the children seemed more interested in playing with blocks and running around outside than watching TV.

Another researcher who was not involved in this study but also focuses his work on kids and television commended Christakis for taking a look at the influence of positive TV programs, instead of focusing on the impact of violent TV.

"I think it's fabulous that people are looking on the positive side. Because no one's going to stop watching TV, we have to have viable alternatives for kids," said Dr. Michael Rich, director of the Center on Media and Child Health at Children's Hospital Boston.

Euro, dollar up after G20, stocks ease on growth concern

LONDON (Reuters) - The euro and the dollar rose against the yen on Monday after the G20 decided not to criticize Japan for its expansionist policies, but shares eased as Europe's weak growth outlook weighed on sentiment.

Financial leaders from the world's 20 biggest economies promised on Saturday not to devalue their currencies to boost exports, aiming to defuse talk of currency wars that had been roiling the markets.

The euro gained 0.2 percent to 125.32 yen, edging up toward a 34-month high of 127.71 yen hit earlier this month, while the dollar rose 0.6 percent to 94 yen, closer to its highest level since May 2010 of 94.46 hit on February 11.

"Future yen direction will continue to be driven by domestic monetary policy from the Bank of Japan and improving international investor confidence, which are both driving the yen weaker," said Lee Hardman, currency analyst at Bank of Tokyo-Mitsubishi UFJ.

Japanese Prime Minister Shinzo Abe is poised to nominate a new BOJ governor. Sources told Reuters that former financial bureaucrat Toshiro Muto, considered likely to be less radical than other candidates, was leading the field.

Abe said on Monday that buying foreign bonds was a future option for the Bank of Japan, which would entail selling of the yen by the central bank.

The euro was also rising against the dollar, gaining 0.1 percent to $1.3375 ahead of address by European Central Bank president Mario Draghi to the region's parliament which may touch on the outlook for the single currency after the G20 meeting.

In European markets, attention was also switching to the release of euro area Purchasing Managers' Indexes for February and German sentiment indices due later in the week, and the upcoming general elections in Italy.

Analysts expect Thursday's euro area flash PMI indices, which point to economic activity around six months out, to show growth stabilizing across the recession-hit region, leaving hopes for a recovery in the second half of the year intact.

Concerns over an inconclusive outcome in Italian elections at the end of the week added to the weaker sentiment as a fragmented parliament could hamper a future government's reform efforts.

The worries about the outlook for Italy were encouraging investors back into safe have German government bonds on Monday, with 10-year Bund yields easing 3.6 basis points to be around 1.63 percent.

"Political uncertainty will keep Bunds well bid this week," ING rate strategist Alessandro Giansanti said, adding that only better than expected economic data could create selling pressure on German debt near term.

EARNINGS HIT

European equity markets were taking their lead from corporate earnings reports which have been reflecting the sluggish economic conditions across the region.

Danish brewer Carlsberg , which generates just over 60 percent of its sales in western Europe, became the latest company to report a weaker-than-expected quarterly profit, sending its shares to lowest level in nearly a month.

The 5 percent drop in price for shares in the world's fourth biggest brewery helped send the FTSEurofirst 300 index <.fteu3> of top European shares down 0.4 percent in morning trade. Germany's DAX <.gdaxi>, the UK FTSE <.ftse> and France's CAC-40 <.fchi> were all also slightly weaker. <.l><.eu/>

Earlier, the effect of the G20 statement and the comments from Abe indicating a renewed drive to stimulate the economy lifted the Nikkei stock index <.n225> by 2.1 percent, near to its highest level since September 2008.

U.S. stock futures were barely changed and are expected to stay little changed as Wall Street will be closed on Monday for the Presidents' Day holiday. <.n/>

MSCI's world equity index <.miwd00000pus> was flat as markets extended two-week period of consolidation that has followed the big run up in January when demand was buoyed by the efforts of global central banks to stimulate the world economy.

Data from EPFR Global, a US-based firm that tracks the flows and allocations of funds globally, shows investors pulled $3.62 billion from U.S. stock funds in the latest week, the most in 10 weeks after taking a neutral stance the prior week.

But demand for emerging market equities remained strong, with investors putting $1.81 billion in new cash into stock funds, the fund-tracking firm said.

CHINA RETURN

In the commodity markets traders played catch up after a week-long holiday last week in China, the world's second biggest consumer of many raw materials, had kept activity subdued, with worries about the euro zone economy weighing on sentiment.

Copper, for which China is the world's largest consumer, fell 0.8 percent to $8,135 a metric ton (1.1023 tons) on the London futures market.

Gold rebounded by 0.3 percent from a six-month low to be $1,614 an ounce as jewelers in China returned to the physical market after the Lunar New Year holiday.

Crude oil markets were mostly steady after some weak U.S. industrial production data on Friday [ID:nL1N0BF44A] was seen dampening demand, while tensions in the Middle East lent some support.

U.S. crude fell 20 cents to $95.66 a barrel but Brent inched up two cents $117.86.

Pakistan faces growing anger over sectarian bombings

QUETTA, Pakistan (Reuters) - Pakistan's unpopular government, which is gearing up for elections expected within months, came under fire on Sunday for failing to improve security after a sectarian bombing in the city of Quetta killed 81 people.

The nuclear-armed country's leaders have done little to contain hardline Sunni Muslim groups which have stepped up a campaign of bombings and assassinations of minority Shi'ites.

On Saturday, Lashkar-e-Jhangvi (LeJ), seen as the most ruthless Sunni sectarian group, claimed responsibility for the attack in Quetta, which deepened suspicions among Shi'ites that Pakistan's intelligence agencies were turning a blind eye to the bloodshed or even supporting extremists.

"The terrorist attack on the Hazara Shi'ite community in Quetta is a failure of the intelligence and security forces," Nawab Zulfiqar Ali Magsi, governor of Baluchistan province, said while touring a hospital.

Leaders of the ethnic Shi'ite Hazara community called on the government to take decisive action, and Pakistanis warned that sectarian violence was spiraling out of control.

"The government is responsible for terrorist attacks and killings in the Hazara community because its security forces have not conducted operations against extremist groups," said Aziz Hazara, vice president of the Hazara Democratic Party.

"We are giving the government 48 hours to arrest the culprits involved in the killing of our people and after that we will launch strong protests."

The death toll from Saturday's bombing rose overnight, with most of the casualties in the main bazaar of the town, capital of Baluchistan, near the border with Afghanistan.

Most of the dead were Hazaras. A senior security official said the figure could rise as 20 people were critically wounded.

On Sunday, people searched for survivors under blocks of cement torn off buildings by the blast. A large blood stain could be seen on a wall near the site.

Many shops and bazaars were closed. Relatives of the wounded responded for an appeal for blood made by hospitals.

"The government knows exactly who is doing what and who is behind all this," said Mohammad Imran, a local trader. "If the government wants (to prevent it), no one can take even a kitchen knife into any market."

POVERTY, CORRUPTION, POWER CUTS

Critics say Pakistan's intelligence agencies previously supported groups like LeJ to fight against Indian forces in Kashmir and failed subsequently to control them.

Now Shi'ites in Quetta and other cities say they are under siege. "We have grown tired of picking up the bodies of our loved ones," said Nasir Ali, 45, a government employee. "I have lost three family members so far in such blasts."

LeJ has also said it was behind a bombing last month in Quetta which killed nearly 100 people, one of Pakistan's worst sectarian attacks.

After that incident, Shi'ite leaders called on Pakistan's military to take over security in Quetta and take on the LeJ.

Growing sectarian violence is piling pressure on the U.S.-backed administration, which already faces a Taliban insurgency, to deliver stability.

"This is a case of barbarity and heartlessness. This is happening because we are divided and not supporting each other," said Malik Afzal, a Sunni student.

"Unless we decide to unite, we will continue to get killed. Today they (Shi'ites) have died. Tomorrow we (Sunni Muslims) will die. The next day, others will get killed."

Pakistani intelligence officials say extremist groups, led by LeJ, want to destabilise the nation through sectarian violence and pave the way for a Sunni theocracy.

More than 400 Shi'ites were killed in Pakistan last year, many by hitmen or bombs. Some hardline Shi'ite groups have struck back by killing Sunni clerics.

"If the government cannot give protection to our community then allow us to protect our own," said Ghulam Abbas, 32, a political worker for the Hazara Democratic Party.

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

Beyoncé's Life Is But a Dream: The Best Moments

TV Watch

By Aaron Parsley

02/16/2013 at 11:05 PM EST

I am ... still singing!

Beyoncé's HBO documentary, Life Is But a Dream, aired Saturday night and it was a 90-minute whirlwind of music, dance and emotion. And though the singer, 31, has been everywhere recently (the Inauguration, the Super Bowl halftime show, Oprah's Next Chapter), the film was full of new and exciting moments. Here are my favorites:

Baby Bey: A home movie of Beyoncé as a little girl playing with bees made my jaw drop. The scene seems to prove what her fans believe: that she was born to be a superstar known as Queen B. I also loved seeing her singing – and being a typical, giggling teenager – with her sister Solange and Kelly Rowland.

The Heartbreak: From her frank discussion of firing her father as a manager to hearing "the saddest song" she's ever written after having miscarriage, the film – which Beyoncé produced and directed herself – had raw, emotional moments.

Mrs. Carter: Life is like a dream for Beyoncé and husband Jay-Z, who surprisingly shared intimate moments together – giddy over her pregnancy, singing Coldplay's "Yellow" to each other, enjoying solitude on a boat in an undisclosed, exotic location. You could feel the love when she toasted him on his birthday.

Blue Ivy: How cute is she?! When Beyoncé and Jay's baby girl, who turned 1 in January, appeared on the screen at the premiere of Life Is But a Dream at New York's Ziegfeld Theater, the crowd gasped and then let out a collective "aww." And I jammed my fingers on the TV screen the first time I watched, trying to pinch those cheeks. Seeing Beyoncé at home with a baby on her hip was a powerful reminder that the fierce superstar is human afterall.

The Music: Of course! Seeing her sing "Listen" with a gorgeously altered ending in a car convinced me of one thing: Beyoncé is definitely not human! I also loved seeing everything that went into her epic Billboard Music Awards performance of "Run the World (Girls)." I just wish I could do that dance. And is it me or does "Resentment" get grittier and angrier every time she performs it?

Praise Beysus and long live the Queen B!

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.

After decent rally, perhaps time for a pause

NEW YORK (Reuters) - Stocks could struggle to extend their seven-week winning streak as the quarterly earnings period draws to a close and the market bumps into strong technical resistance.

Many analysts say the market could spend the next few weeks consolidating gains that have lifted the benchmark Standard & Poor's 500 <.spx> by 6.6 percent since the start of the year.

The S&P 500 ended up 0.1 percent for the week, recovering from a late sell-off on Friday after a Bloomberg report about slow February sales at Wal-Mart triggered a slide in the retailer's shares. It was the index's seventh week of gains.

Odds of a pullback are increasing, with the market in slightly overbought territory, said Bruce Zaro, chief technical strategist at Delta Global Asset Management in Boston.

"I do suspect the closing of the earnings season will lead to at least a pause and possibly a pullback," Zaro said. The S&P 500 could shave 3 to 5 percent between now and early April, he said.

Fourth-quarter earnings have mostly beaten expectations. Year-over-year profit growth for S&P 500 companies is now estimated at 5.6 percent, up from a January 1 forecast for 2.9 percent growth, and 70 percent of companies are exceeding analyst profit expectations, above the 62 percent long-term average, according to Thomson Reuters data.

On Thursday, Wal-Mart, the world's largest retailer, is due to report results, unofficially closing out the earnings period. Investors will be keen to see its quarterly numbers, especially after the Friday's news report that rattled investors.

The S&P 500 has gained 4.3 percent since Alcoa kicked off the earnings season on January 8.

The approaching March 1 deadline for across-the-board federal budget cuts unless Congress reaches a compromise adds another reason for caution, especially with recent economic data indicating the recovery remains bumpy.

Manufacturing output fell 0.4 percent last month, the Federal Reserve said on Friday, but production in November and December was much stronger than previously thought.

TESTING RESISTANCE

The S&P 500 has been trading near five-year highs, and it notched its highest level since November 2007 this week. But the gains have pushed the benchmark index almost as far as it is likely to go in the near term, with strong resistance hovering around 1,525 and 1,540, one analyst said.

As a result, the index is set to move sideways, said Dave Chojnacki, market technician at Street One Financial in Huntington Valley, Pennsylvania. "We just don't have the volume or the catalyst right now" to go above those levels, he said.

At the same time, other analysts say, the market has not shown significant signs of slowing, including a break below 15- and 30-day moving averages.

Such moves would be needed to show that momentum is slowing or that the market is at risk of a correction, said Todd Salamone, director of research for Schaeffer's Investment Research in Cincinnati, Ohio. The S&P 500's 14-day moving average is at 1,511 while the 30-day is at 1,494. The index closed Friday at 1,519.

Recent M&A activity, including news this week of a merger between American Airlines and US Airways Group , helped provide some strength for the market this week and optimism that more deals may be on the way.

In the coming days, the market will focus on minutes from the latest Federal Reserve meeting, due to be released on Wednesday, which could provide support if they suggest the Fed will remain on its current course of aggressive monetary easing.

The Fed minutes released in January spooked markets a bit when they revealed that some Fed officials thought it would be appropriate to consider ending asset purchases later in 2013. U.S. Treasury yields rose on that news, though market worries about a near-term end to quantitative easing have since faded.

Among other companies expected to report earnings next week are Nordstrom , Hewlett-Packard and Marriott International
