Sex to burn calories? Authors expose obesity myths

Fact or fiction? Sex burns a lot of calories. Snacking or skipping breakfast is bad. School gym classes make a big difference in kids' weight.

All are myths or at least presumptions that may not be true, say researchers who reviewed the science behind some widely held obesity beliefs and found it lacking.

Their report in Thursday's New England Journal of Medicine says dogma and fallacies are detracting from real solutions to the nation's weight problems.

"The evidence is what matters," and many feel-good ideas repeated by well-meaning health experts just don't have it, said the lead author, David Allison, a biostatistician at the University of Alabama at Birmingham.

Independent researchers say the authors have some valid points. But many of the report's authors also have deep financial ties to food, beverage and weight-loss product makers — the disclosures take up half a page of fine print in the journal.

"It raises questions about what the purpose of this paper is" and whether it's aimed at promoting drugs, meal replacement products and bariatric surgery as solutions, said Marion Nestle, a New York University professor of nutrition and food studies.

"The big issues in weight loss are how you change the food environment in order for people to make healthy choices," such as limits on soda sizes and marketing junk food to children, she said. Some of the myths they cite are "straw men" issues, she said.

But some are pretty interesting.

Sex, for instance. Not that people do it to try to lose weight, but claims that it burns 100 to 300 calories are common, Allison said. Yet the only study that scientifically measured the energy output found that sex lasted six minutes on average — "disappointing, isn't it?" — and burned a mere 21 calories, about as much as walking, he said.

That's for a man. The study was done in 1984 and didn't measure the women's experience.

Among the other myths or assumptions the authors cite, based on their review of the most rigorous studies on each topic:

—Small changes in diet or exercise lead to large, long-term weight changes. Fact: The body adapts to changes, so small steps to cut calories don't have the same effect over time, studies suggest. At least one outside expert agrees with the authors that the "small changes" concept is based on an "oversimplified" 3,500-calorie rule, that adding or cutting that many calories alters weight by one pound.

—School gym classes have a big impact on kids' weight. Fact: Classes typically are not long, often or intense enough to make much difference.

—Losing a lot of weight quickly is worse than losing a little slowly over the long term. Fact: Although many dieters regain weight, those who lose a lot to start with often end up at a lower weight than people who drop more modest amounts.

—Snacking leads to weight gain. Fact: No high quality studies support that, the authors say.

—Regularly eating breakfast helps prevent obesity. Fact: Two studies found no effect on weight and one suggested that the effect depended on whether people were used to skipping breakfast or not.

—Setting overly ambitious goals leads to frustration and less weight loss. Fact: Some studies suggest people do better with high goals.

Some things may not have the strongest evidence for preventing obesity but are good for other reasons, such as breastfeeding and eating plenty of fruits and vegetables, the authors write. And exercise helps prevent a host of health problems regardless of whether it helps a person shed weight.

"I agree with most of the points" except the authors' conclusions that meal replacement products and diet drugs work for battling obesity, said Dr. David Ludwig, a prominent obesity research with Boston Children's Hospital who has no industry ties. Most weight-loss drugs sold over the last century had to be recalled because of serious side effects, so "there's much more evidence of failure than success," he said.

Wall Street ends lower after Fed statement

NEW YORK (Reuters) - Stocks fell on Wednesday after the Federal Reserve said in its latest statement that economic growth had stalled but indicated the pullback was likely temporary.

Stocks were flat for most of the session prior to the Fed statement at the end of a two-day policy meeting. The Fed repeated its pledge to keep purchasing securities until employment improves substantially.

The statement followed data that showed the economy, as measured by gross domestic product, unexpectedly contracted in the fourth quarter. Economists stressed that the 0.1 percent contraction, caused partly by a plunge in government spending and lower business inventories, is not an indicator of recession.

"The unemployment rate is likely to fall below 6.5 percent next year, so the Fed may be raising interest rates as soon as mid-2014. The fiscal drag from the tax increases will be offset this quarter by rebuilding post-Sandy, so real GDP growth should still come in at 2 percent," said Kurt Karl, chief economist at Swiss Re.

The S&P 500 held above 1,500, seen by technical analysts as an inflection point that will determine the overall direction in the near term. The index is on track to post its best month since October 2011 and its best January since 1997.

"This is a very modest pullback after a steep run," said Paul Zemsky, head of asset allocation at ING Investment Management in New York.

"It is too soon for the Fed to start talking about the end of (their bond buying program). The economy needs stimulus to sustain this recovery."

Chesapeake Energy rose 6 percent to $20.11 a day after it said Aubrey McClendon would step down as chief executive. The company has had a tumultuous year in which a series of Reuters investigations triggered civil and criminal probes of the second-largest U.S. natural gas producer.

After the bell, shares of Facebook Inc fell 5.9 percent to $29.40 following the company's earnings announcement. Facebook said its revenue in the fourth quarter grew 40 percent year-on-year to $1.585 billion.

Both Boeing Co and Amazon.com shares gained after earnings beat expectations, continuing a trend this quarter of high-profile names advancing after results.

Amazon rose 4.8 percent to $272.76 and Boeing rose 1.3 percent to $74.59.

The Dow Jones industrial average <.dji> was down 44.00 points, or 0.32 percent, at 13,910.42. The Standard & Poor's 500 Index <.spx> was down 5.88 points, or 0.39 percent, at 1,501.96. The Nasdaq Composite Index <.ixic> was down 11.35 points, or 0.36 percent, at 3,142.31.

Thomson Reuters data showed that of the 192 companies in the S&P 500 that have reported earnings this season, 68.8 percent have been above analyst expectations, which is a higher proportion than over the past four quarters and above the average since 1994.

Research In Motion shares fell 12 percent to $13.78 after the company, which is changing its name to BlackBerry, unveiled a long-delayed line of smartphones in hopes of a comeback into a market it once dominated.

Giving the market extra support, private sector employment topped forecasts with the ADP National Employment report showing 192,000 jobs were added in January, higher than the 165,000 expectation.

Sixty-five people executed in Syria's Aleppo: activists

BEIRUT (Reuters) - At least 65 people were found shot dead with their hands bound in the northern Syrian city of Aleppo on Tuesday in a "new massacre" in the near two-year revolt against President Bashar al-Assad, activists said.

Opposition campaigners blamed the government but it was impossible to confirm who was responsible. Assad's forces and rebels have been battling in Syria's commercial hub since July and both have been accused of carrying out summary executions.

U.N.-Arab League mediator Lakhdar Brahimi told the U.N. Security Council "unprecedented levels of horror" had been reached in Syria, and that both the government and rebels had committed atrocious crimes, diplomats said.

He appealed to the 15-nation council to overcome its deadlock and take action to help end the civil war in which Syria is "breaking up before everyone's eyes".

More than 60,000 people are estimated to have been killed in the war, the longest and deadliest of the revolts that began throughout the Arab world two years ago.

The U.N. refugee agency said the fighting had forced more than 700,000 people to flee. World powers fear the conflict could envelop Syria's neighbors including Lebanon, Jordan and Turkey, further destabilizing an already explosive region.

Opposition activists posted a video of at least 51 muddied male bodies alongside what they said was the Queiq River in Aleppo's rebel-held Bustan al-Qasr neighborhood.

The bodies had what looked like bullet wounds in their heads and some of the victims appeared to be young, possibly teenagers, dressed in jeans, shirts and trainers.

Aleppo-based opposition activists who asked not to be named for security reasons blamed pro-Assad militia fighters.

They said the men had been executed and dumped in the river before floating downstream into the rebel area. State media did not mention the incident.

The British-based Syrian Observatory for Human Rights, which says it provides objective information about casualties on both sides of Syria's war from a network of monitors, said the footage was evidence of a new massacre and the death toll could rise as high as 80.

"They were killed only because they are Muslims," said a bearded man in another video said to have been filmed in central Bustan al-Qasr after the bodies were removed from the river. A pickup truck with a pile of corpses was parked behind him.

STALEMATE

It is hard for Reuters to verify such reports from inside Syria because of restrictions on independent media.

Rebels are stuck in a stalemate with government forces in Aleppo - Syria's most populous city which is divided roughly in half between the two sides.

The revolt started as a peaceful protest movement against more than four decades of rule by Assad and his family, but turned into an armed rebellion after a government crackdown.

About 712,000 Syrian refugees have registered in other countries in the region or are awaiting processing as of Tuesday, the U.N. refugee agency said.

"We have seen an unrelenting flow of refugees across all borders. We are running double shifts to register people," Sybella Wilkes, spokeswoman for the U.N. High Commissioner for Refugees (UNHCR), told Reuters in Geneva.

The United Nations said it had received aid promises ahead of a donor conference in Kuwait on Wednesday where it is seeking $1.5 billion for refugees and people inside Syria. Washington announced an additional $155 million that its said brought the total U.S. humanitarian aid to the crisis to some $365 million.

Aid group Médecins Sans Frontières said the bulk of the current aid was going to government-controlled areas in Syria and called on donors to make sure they were even-handed.

MISSILES

In the eastern city of Deir al-Zor, insurgents including al Qaeda-linked Islamists captured a security agency after days of heavy fighting, according to an activist.

Some of the fighters were shown carrying a black flag with the Islamic declaration of faith and the name of the al-Nusra Front, which has ties to al Qaeda in neighboring Iraq.

The war has become heavily sectarian, with rebels who mostly come from the Sunni Muslim majority fighting an army whose top generals are mostly from Assad's Alawite sect, an offshoot of Shi'ite Islam. Assad has framed the revolt as a foreign-backed conspiracy and blames the West and Sunni Gulf states.

Fighting also took place in the northern town of Ras al-Ain, on the border with Turkey, between rebels and Kurdish militants, the Observatory said.

In Turkey, a second pair of Patriot missile batteries being sent by NATO countries are now operational, a German security official said.

The United States, Germany and the Netherlands each committed to sending two batteries and up to 400 soldiers to operate them after Ankara asked for help to bolster its air defenses against possible missile attack from Syria.

BlackBerry 10 said to be inadequate for helping RIM overcome its ‘demons’

After hitting a seven-year low of $ 6.22 this past summer, shares of Research in Motion (RIMM) have rebounded and climbed more than 100% in the past six months. The company that was previously written off by Wall Street investors has seen a significant boost in recent months as anticipation grows for its BlackBerry 10 operating system. But while a number of analysts have voiced their support for RIM, not everyone is convinced.

[More from BGR: Apple’s 128GB iPad shows the world exactly what Apple does best]

Jan Dawson of Ovum explained, per Benzinga, that RIM continues to “face the twin demons of consumer-driven buying power and a chronic inability to appeal to mature market consumers,” and he believes BlackBerry 10 won’t change this. The analyst said that due to a strong user base of 79 million subscribers and profitability still in the black, the company will remain for years to come. He was quick to note, however, that its glory days are in the past and “it is only a matter of time before it reaches a natural end.”

[More from BGR: Apple unveils new 128GB iPad]

Dawson previously wrote that RIM’s strategy seems to be focused on building the best devices for current BlackBerry users “rather than something that will necessarily win converts from other platforms.”

“The points of differentiation RIM has focused on in teasers for the new platform confirm this – better multitasking, productivity, email, contacts and calendar applications and so on, rather than a better gaming, content consumption or social networking experience,” he said.

Shares of RIM are down more than 6% on Monday, a day before the company is set to unveil its BlackBerry 10 operating system.

Soldier with new arms determined to be independent

BALTIMORE (AP) — After weeks of round-the-clock medical care, Brendan Marrocco insisted on rolling his own wheelchair into a news conference using his new transplanted arms. Then he brushed his hair to one side.

Such simple tasks would go unnoticed in most patients. But for Marrocco, who lost all four limbs while serving in Iraq, these little actions demonstrate how far he's come only six weeks after getting a double-arm transplant.

Wounded by a roadside bomb in 2009, the former soldier said he could get by without legs, but he hated living without arms.

"Not having arms takes so much away from you. Even your personality, you know. You talk with your hands. You do everything with your hands, and when you don't have that, you're kind of lost for a while," the 26-year-old New Yorker told reporters Tuesday at Johns Hopkins Hospital.

Doctors don't want him using his new arms too much yet, but his gritty determination to regain independence was one of the chief reasons he was chosen to receive the surgery, which has been performed in the U.S. only seven times.

That's the message Marrocco said he has for other wounded soldiers.

"Just not to give up hope. You know, life always gets better, and you're still alive," he said. "And to be stubborn. There's a lot of people who will say you can't do something. Just be stubborn and do it anyway. Work your ass off and do it."

Dr. W.P. Andrew Lee, head of the team that conducted the surgery, said the new arms could eventually provide much of the same function as his original arms and hands. Another double-arm transplant patient can now use chopsticks and tie his shoes.

Lee said Marrocco's recovery has been remarkable, and the transplant is helping to "restore physical and psychological well-being."

Tuesday's news conference was held to mark a milestone in his recovery — the day he was to be discharged from the hospital.

Next comes several years of rehabilitation, including physical therapy that is going to become more difficult as feeling returns to the arms.

Before the surgery, he had been living with his older brother in a specially equipped home on New York's Staten Island that had been built with the help of several charities. Shortly after moving in, he said it was "a relief to not have to rely on other people so much."

The home was heavily damaged by Superstorm Sandy last fall.

"We'll get it back together. We've been through a lot worse than that," his father, Alex Marrocco, said.

For the next few months, Marrocco plans to live with his brother in an apartment near the hospital.

The former infantryman said he can already move the elbow on his left arm and rotate it a little bit, but there hasn't been much movement yet for his right arm, which was transplanted higher up.

Marrocco's mother, Michelle Marrocco, said he can't hug her yet, so he brushes his left arm against her face.

The first time he moved his left arm was a complete surprise, an involuntary motion while friends were visiting him in the hospital, he said.

"I had no idea what was going through my mind. I was with my friends, and it happened by accident," he recalled. "One of my friends said 'Did you do that on purpose?' And I didn't know I did it."

Marrocco's operation also involved a technical feat not tried in previous cases, Lee said in an interview after the news conference.

A small part of Marrocco's left forearm remained just below his elbow, and doctors transplanted a whole new forearm around and on top of it, then rewired nerves to serve the old and new muscles in that arm.

"We wanted to save his joint. In the unlucky event we would lose the transplant, we still wanted him to have the elbow joint," Lee said.

He also explained why leg transplants are not done for people missing those limbs — "it's not very practical." That's because nerves regrow at best about an inch a month, so it would be many years before a transplanted leg was useful.

Even if movement returned, a patient might lack sensation on the soles of the feet, which would be unsafe if the person stepped on sharp objects and couldn't feel the pain.

And unlike prosthetic arms and hands, which many patients find frustrating, the ones for legs are good. That makes the risks of a transplant not worth taking.

"It's premature" until there are better ways to help nerves regrow, Lee said.

Now Marrocco, who was the first soldier to survive losing all four limbs in the Iraq War, is looking forward to getting behind the wheel of his black 2006 Dodge Charger and hand-cycling a marathon.

Asked if he could one day throw a football, Dr. Jaimie Shores said sure, but maybe not like Baltimore Ravens quarterback Joe Flacco.

"Thanks for having faith in me," Marrocco interjected, drawing laughter from the crowd.

His mother said Marrocco has always been "a tough cookie."

"He's not changed that, and he's just taken it and made it an art form," Michelle Marrocco said. "He's never going to stop. He's going to be that boy I knew was going to be a pain in my butt forever. And he's going to show people how to live their lives."

Wall Street advances as defensive stocks extend rally

NEW YORK (Reuters) - Stocks advanced on Tuesday, led by defensive sectors, in a sign the cash piles recently moving into the market are being put to use by cautious investors to pick up more gains.

The S&P 500 is on track to post its best monthly performance since October 2011 and its best January since 1997 as investors poured $55 billion in new cash into stock mutual funds and exchange-traded funds in January, the biggest monthly inflow on record. [ID:nL1N0AX45Q] The Dow Jones industrial average has been flirting with 14,000, a level it hasn't seen since October 2007.

Shares of Amazon.com jumped nearly 7 percent in extended trade after the world's largest Internet retailer posted fourth-quarter revenue that jumped 22 percent to $21.27 billion. The stock closed down 5.7 percent at $260.35 in regular trading.

Among rising defensive shares, which are companies relatively immune to economic swings, were drugmaker Pfizer , up 3.2 percent to $27.70 after posting earnings and AT&T , 1.6 percent higher at $34.68.

"Cyclical were moving very nicely, now you see balance with some of the defensive. Many managers use that as an internal hedge in equity portfolios," said Quincy Krosby, market strategist at Prudential Financial in Newark, New Jersey.

She said the market is cautious ahead of Wednesday's statement following the Federal Reserve's two-day meeting. In addition, defensive stocks would hold up better if Friday's payrolls report surprises on the downside.

The S&P hovered near 1,500, and market technicians say the benchmark is at an inflection point which will determine the overall direction in the near term.

"The public is pouring in now," said Carter Worth, chief market technician at Oppenheimer & Co in New York. "It reflects complacency and that typically leads to hubris, and hubris leads to trouble. Everyone's buying."

The top performing sectors on the S&P 500 were healthcare <.spxhc> and telecom services <.splrcl>, so-called defensive sectors, both up more than 1 percent.

The energy sector also advanced, on the back of strong earnings from Valero Energy Corp and a hedge fund move to break up Hess Corp to boost investor returns.

Valero shares jumped 12.8 percent to $43.77 and Hess gained 9 percent to $68.11.

The equity gains have largely come on a strong start to earnings season, though results were mixed on Tuesday with Pfizer rising but Ford Motor Co down after its report.

Both companies reported profits that topped expectations, but Ford also forecast a wider loss in its European segment. Ford dropped 4.6 percent to $13.14 as one of the biggest percentage losers on the S&P 500.

The Dow Jones industrial average <.dji> was up 72.49 points, or 0.52 percent, at 13,954.42. The Standard & Poor's 500 Index <.spx> was up 7.66 points, or 0.51 percent, at 1,507.84. The Nasdaq Composite Index <.ixic> was down 0.64 points, or 0.02 percent, at 3,153.66.

Thomson Reuters data showed that of the 174 companies in the S&P 500 that have reported earnings this season, 68.4 percent have been above analyst expectations, which is a higher proportion than over the past four quarters and above the average since 1994.

Disappointing outlooks from Seagate Technology and BMC Software pressured their shares. Seagate lost 9.4 percent to $33.91 and BMC fell 6.3 percent to $41.71.

D.R. Horton Inc's quarterly profit more than doubled as it managed to sell more homes at higher prices, leading the No. 1 U.S. homebuilder to forecast a good spring selling season. The stock jumped 11.8 percent to $23.82.

U.S. home prices rose in November to rack up their best yearly gain since the housing crisis began, a further sign that the sector is on the mend, but consumer confidence fell to its lowest level in more than a year in the wake of higher taxes for many Americans.

French seal off Mali's Timbuktu, rebels torch library

GAO, Mali (Reuters) - French and Malian troops retook control of Timbuktu, a UNESCO World Heritage site, on Monday after Islamist rebel occupiers fled the ancient Sahara trading town and torched several buildings, including a library holding priceless manuscripts.

The United States and the European Union are backing a French-led intervention in Mali against al Qaeda-allied militants they fear could use the West African state's desert north as a springboard for international attacks.

The recovery of Timbuktu followed the swift capture by French and Malian forces at the weekend of Gao, another major town in Mali's north that had been occupied by the alliance of jihadist groups since last year.

The two-week-old mission by France in its former Sahel colony, at the request of Mali's government, has driven the Islamist rebels northwards out of towns into the desert and mountains.

Without a shot being fired, 1,000 French soldiers and paratroopers and 200 Malian troops seized Timbuktu airport and surrounded the town on the banks of the Niger River, looking to block the escape of insurgents.

In both Timbuktu and Gao, cheering crowds turned out to welcome the French and Malian troops.

A third town in Mali's vast desert north, Kidal, had remained in Islamist militant hands. But Malian Tuareg MNLA rebels, who are seeking autonomy for their northern region, said on Monday they had taken charge in Kidal after Islamist fighters abandoned it.

A diplomat in Bamako confirmed the MNLA takeover of Kidal.

A French military spokesman said the assault forces at Timbuktu were avoiding any fighting inside the city to protect the cultural treasures, mosques and religious shrines in what is considered a seat of Islamic learning.

But Timbuktu Mayor Ousmane Halle told Reuters departing Islamist gunmen had four days earlier set fire to the town's new Ahmed Baba Institute, which contained thousands of manuscripts.

UNESCO spokesman Roni Amelan said the Paris-based U.N. cultural agency was "horrified" by the news of the fire, but was awaiting a full assessment of the damage.

Ali Baba, a worker at the Ahmed Baba Institute, told Sky News in Timbuktu more than 3,000 manuscripts had been destroyed. "They are bandits. They have burned some manuscripts and also stole a lot of manuscripts which they took with them," he said.

Marie Rodet, an African history lecturer at Britain's School of Oriental and African Studies, said Timbuktu held one of the greatest libraries of Islamic manuscripts in the world.

"It's pure retaliation. They (the Islamist militant rebels) knew they were losing the battle and they hit where it really hurts," Rodet told Reuters. "These people are not interested in any intellectual debate. They are anti-intellectual."

ISLAMISTS "ALL FLED"

The Ahmed Baba Institute, one of several libraries and collections in Timbuktu containing fragile documents dating back to the 13th century, is named after a Timbuktu-born contemporary of William Shakespeare and houses more than 20,000 scholarly manuscripts. Some were stored in underground vaults.

The French and Malians have encountered no resistance so far in Timbuktu. But they will now have to comb through a labyrinth of ancient mosques, monuments, mud-brick homes and narrow alleyways to flush out any hiding fighters.

The Islamist forces comprise a loose alliance that groups Al Qaeda in the Islamic Maghreb (AQIM) with Malian Islamist group Ansar Dine and AQIM splinter MUJWA.

They have retreated in the face of relentless French air strikes and superior firepower and are believed to be sheltering in the rugged Adrar des Ifoghas mountain range, north of Kidal.

The MNLA Tuareg rebels who say they now hold Kidal have offered to help the French-led offensive against the al Qaeda-affiliated Islamists. It was not clear, however, whether the French and Malians would steer their offensive further towards Kidal, or hold negotiations with the MNLA.

FRANCE: MALI "BEING LIBERATED"

The world was shocked by Timbuktu's capture in April by Tuareg fighters, whose separatist rebellion was later hijacked by Islamist radicals who imposed severe sharia (Islamic law).

Provoking international outrage, the Muslim militants - who follow a more radical Salafist brand of Islam - destroyed dozens of ancient shrines in Timbuktu sacred to Sufi Muslims, condemning them as idolatrous and un-Islamic.

They also imposed a strict form of Islamic law, or sharia, authorizing the stoning of adulterers and amputations for thieves, while forcing women to go veiled.

On Sunday, many women among the thousands of Gao residents who came out to celebrate the rebels' expulsion made a point of going unveiled. Other residents smoked cigarettes and played music to flout the bans previously imposed by the rebels.

Hundreds of troops from Niger and Chad have been brought to Gao to help secure the town.

"Little by little, Mali is being liberated," French Foreign Minister Laurent Fabius told France 2 television.

Speaking at a news conference in Paris, French President Francois Hollande said French troops would take a step back once the job of retaking key towns was complete, and Malian and other African troops would take over the task of hunting the rebels.

"They are the ones who will go into the northern part, which we know is the most difficult because that's where the terrorists are hiding," Hollande said.

As the French and Malian troops thrust into northern Mali, African troops for a U.N.-backed continental intervention force for Mali, expected to number 7,700, are being flown into the country, despite severe delays and logistical problems.

Outgoing African Union Chairman President Thomas Boni Yayi of Benin scolded AU states at a weekend summit in Addis Ababa for their slow response to assist Mali while former colonial power France took the lead in the military operation.

Burkina Faso, Benin, Nigeria, Senegal, Togo, Niger and Chad are providing soldiers for the AFISMA force. Burundi and other nations have pledged to contribute.

AU Peace and Security Commissioner Ramtane Lamamra said these regional troops could play a useful "clean-up" role once the main military operations against the Islamist rebels end.

Speaking in Addis Ababa on Monday, U.N. Secretary-General Ban Ki-moon said the U.N. was "actively considering" helping the troop-contributing African countries with logistical support.

Yahoo revenue rises on search advertising

(Reuters) – Yahoo Inc posted a 4 percent gain in net revenue to $ 1.22 billion in the fourth quarter, when an increase in search advertising sales offset weakness in the Web portal’s display ad business.

The company forecast net revenue — which excludes fees shared with partner websites — of $ 1.07 billion to $ 1.1 billion in the current quarter, trailing the $ 1.1 billion that Wall Street analysts expect on average.

Shares in Yahoo, which is trying to stave off declines across much of its business and revive growth, were up 1.5 percent in after hours trade. They had risen 4.5 percent before the revenue projections were disclosed on an analysts’ conference call.

“We got the revenue acceleration we were hoping for. Display was down, but search is doing better” said Sameet Sinha, an analyst at B. Riley Caris.

“As long as in the near-term things are not bad, I think the stock will generally act positively while we wait for Marissa Mayer to deliver,” said Sinha.

The company said on Monday its fourth-quarter net income was $ 272.3 million, or 23 cents per share, versus $ 295.6 million, or 24 cents per share in the year-ago period.

Excluding certain items, Yahoo said it had earnings per share of 32 cents, versus the average analyst expectation of 28 cents according to Thomson Reuters I/B/E/S.

Chief Executive Marissa Mayer is moving to revive the company’s fortunes after several years of declining revenue. Yahoo’s stock has risen roughly 30 percent since she became CEO, reaching its highest levels since 2008.

Yahoo said it repurchased $ 1.5 billion worth of shares during the fourth quarter. Shares in the company were up 1.5 percent at $ 20.61 in extended trading from a close of $ 20.31 on the Nasdaq.

Soldier who lost 4 limbs has double-arm transplant

On Facebook, he describes himself as a "wounded warrior...very wounded."

Brendan Marrocco was the first soldier to survive losing all four limbs in the Iraq War, and doctors revealed Monday that he's received a double-arm transplant.

Those new arms "already move a little," he tweeted a month after the operation.

Marrocco, a 26-year-old New Yorker, was injured by a roadside bomb in 2009. He had the transplant Dec. 18 at Johns Hopkins Hospital in Baltimore, his father said Monday.

Alex Marrocco said his son does not want to talk with reporters until a news conference Tuesday at the hospital, but the younger Marrocco has repeatedly mentioned the transplant on Twitter and posted photos.

"Ohh yeah today has been one month since my surgery and they already move a little," Brendan Marrocco tweeted Jan. 18.

Responding to a tweet from NASCAR driver Brad Keselowski, he wrote: "dude I can't tell you how exciting this is for me. I feel like I finally get to start over."

The infantryman also received bone marrow from the same dead donor who supplied his new arms. That novel approach is aimed at helping his body accept the new limbs with minimal medication to prevent rejection.

The military sponsors operations like these to help wounded troops. About 300 have lost arms or hands in Iraq or Afghanistan.

Unlike a life-saving heart or liver transplant, limb transplants are aimed at improving quality of life, not extending it. Quality of life is a key concern for people missing arms and hands — prosthetics for those limbs are not as advanced as those for feet and legs.

"He was the first quad amputee to survive," and there have been four others since then, Alex Marrocco said.

The Marroccos want to thank the donor's family for "making a selfless decision ... making a difference in Brendan's life," the father said.

Brendan Marrocco has been in public many times. During a July 4 visit last year to the Sept. 11 Memorial with other disabled soldiers, he said he had no regrets about his military service.

"I wouldn't change it in any way. ... I feel great. I'm still the same person," he said.

The 13-hour operation was led by Dr. W.P. Andrew Lee, plastic surgery chief at Johns Hopkins. It was the seventh double-hand or double-arm transplant done in the United States.

Lee led three of those earlier operations when he worked at the University of Pittsburgh, including the only above-elbow transplant that had been done at the time, in 2010.

Marrocco's "was the most complicated one" so far, Lee said in an interview Monday. It will take more than a year to know how fully Marrocco will be able to use the new arms.

"The maximum speed is an inch a month for nerve regeneration," he explained. "We're easily looking at a couple years" until the full extent of recovery is known.

While at Pittsburgh, Lee pioneered the immune-suppression approach used for Marrocco. The surgeon led hand-transplant operations on five patients, giving them marrow from their donors in addition to the new limbs. All five recipients have done well, and four have been able to take just one anti-rejection drug instead of combination treatments most transplant patients receive.

Minimizing anti-rejection drugs is important because they have side effects and raise the risk of cancer over the long term. Those risks have limited the willingness of surgeons and patients to do more hand, arm and even face transplants.

Lee has received funding for his work from AFIRM, the Armed Forces Institute of Regenerative Medicine, a cooperative research network of top hospitals and universities around the country that the government formed about five years ago. With government money, he and several other plastic surgeons around the country are preparing to do more face transplants, possibly using the new immune-suppression approach.

Marrocco expects to spend three to four months at Hopkins, then return to a military hospital to continue physical therapy, his father said. Before the operation, he had been fitted with prosthetic legs and had learned to walk on his own.

He had been living with his older brother in a specially equipped home on New York's Staten Island that had been built with the help of several charities. Shortly after moving in, he said it was "a relief to not have to rely on other people so much."

The home was heavily damaged by Superstorm Sandy last fall.

Despite being in a lot of pain for some time after the operation, Marrocco showed a sense of humor, his father said. He had a hoarse voice from the tube that was in his throat during the long surgery and decided he sounded like Al Pacino. He soon started doing movie lines.

"He was making the nurses laugh," Alex Marrocco said.
