Vital Signs: Smoking Tied to Less Dense Bones for Girls

Smoking in teenage girls is associated with slower development of bone mineral density, a new study reports.

The scientists studied 262 healthy girls ages 11 to 19, using questionnaires and interviews to assess their smoking habits. The researchers also measured the girls’ bone density at the hip and lumbar spine three times at one-year intervals.

Smokers entered adolescence with the same lumbar and hip bone density as nonsmokers, but by age 19, they were about a year behind on average. After adjusting for other factors that affect bone health — height, weight, hormonal contraceptive use and more — the researchers found that even relatively low or irregular rates of smoking were independently associated with lower bone density.

The study, published last week in The Journal of Adolescent Health, used a sample that fell below national averages for calcium intake and physical activity, so the results may not be generalizable to wider populations.

The lead author, Lorah D. Dorn, a professor of pediatrics at Cincinnati Children’s Hospital, pointed out that this is only one study and that more research is needed. Still, she said, “It tells me that for care providers — clinicians and parents — this needs to be something they’re vigilant about.”

Euro Watch: Bonds in Spain and Italy Shaken by Italian Politics





ROME — Italian stock and bond prices fell on Monday after a weekend of political turmoil in Italy gave rise to fears that the country was headed for renewed instability.




Shares of Italian banks, which are big holders of the government’s bonds, were among the hardest hit.


The action occurred in the first day of trading after Prime Minister Mario Monti said over the weekend that he would soon step down after his predecessor, Silvio Berlusconi, withdrew his party’s support from Mr. Monti and said he would again seek election as prime minister.


Mr. Berlusconi, who was elected prime minister three times, left office a year ago as markets pushed Italy to the brink of financial collapse. Mr. Monti, an economist who was appointed as his temporary successor, has restored Italy’s credibility with investors, who have given the country a break on its borrowing costs. But those gains have come at the cost of painful austerity measures that have worsened the country’s economic situation and given Mr. Berlusconi an opening to attack.


The Milan benchmark index, MIB, fell more than 2 percent on Monday. Italian banks, which remain sensitive to declines in the country’s bond prices, were among the big losers. Intesa Sanpaolo, the most active stock, fell 5.2 percent, as did UniCredit.


Mr. Monti, who joined other leaders in Oslo on Monday to receive the Nobel Peace Prize awarded to the European Union, said at a news conference that the market reactions “need not be dramatized.”


“I am confident,” he said, that the Italian elections would result in a government “that will be responsible and oriented toward the E.U. and this will be in line with efforts the Italian government has made so far.”


The decline in bond prices sent their yields, or interest rates, higher — an indicator of the Italian government’s borrowing costs. The spread between interest rates on Italian 10-year sovereign bonds and equivalent German securities, the European benchmark for safety, grew to 3.5 percentage points on Monday. That was up from 3.25 percentage points late Friday, suggesting that investors were growing more wary of holding Italian debt.


The yield on Italian 10-year bonds, which breached 7 percent this year, ended trading on Monday at 4.8 percent, up 29 basis points. A basis point is one-hundredth of a percent.


Bonds of Spain, which is the other big economy of concern in the euro zone, also came under renewed pressure on Monday after Mr. Monti’s announcement.


The spread between Spanish 10-year bonds and equivalent German bonds widened to 4.27 percentage points from 4.16 points on Friday. The yield on the benchmark Spanish 10-year rose 10 basis points, to 5.5 percent; it reached 7.1 percent in July amid concerns that Spain would be forced into a full bailout after having to negotiate a 100 billion euro, or $129 billion, rescue package for its banks in June.


Luis de Guindos, the Spanish economy minister, warned that Italy’s political turmoil would affect his country.


“When doubts emerge over the stability of a neighboring country like Italy, which is also seen as vulnerable, there’s an immediate contagion for us,” he said Monday morning on Spanish national radio.


Asked whether Spain would itself seek further European rescue funding, he instead said, “The help that Spain needs is that the doubts over the future of the euro be removed.”


Speaking before the Nobel ceremony on Monday, the European Commission president, JosĂ© Manuel Barroso, said Italy must “continue on the road of structural reforms.” The elections, Mr. Barroso said on Sky News, “must not be used to postpone reforms.”


A dismal economic report on Monday served as a reminder that despite Mr. Monti’s success with investors, the real economy continues to suffer. Italian industrial production fell a seasonally adjusted 1.1 percent in October from September, and by 6.2 percent from a year earlier, Istat, the national statistics agency, said.


Some analysts said they thought that Mr. Berlusconi’s re-emergence as a political leader was as responsible for unnerving investors as Mr. Monti’s unexpected decision to resign. Nicholas Spiro, managing director of Spiro Sovereign Strategy, a research firm, wrote on Monday in a note that Mr. Berlusconi remained “the boogeyman of investors,” who “epitomizes the dysfunctional nature of Italian politics.”


Angela Merkel, the German chancellor, was to meet on Monday with Mr. Monti on the sidelines of the Nobel ceremony, said Georg Streiter, a spokesman for the chancellor.


Ms. Merkel pushed to have Mr. Monti succeed Mr. Berlusconi. But she ended up facing Mr. Monti’s own ideas for economic change, which focused more on growth and job creation than on the austere fiscal discipline championed by Ms. Merkel.


As a rule, the German government does not comment on its partners’ domestic politics, but Foreign Minister Guido Westerwelle warned that an attempt to scale back Italy’s reform push could result in further destabilization in the euro zone.


“Italy cannot remain stagnant on two-thirds of its reform process,” Mr. Westerwelle said through a spokesman. “This would throw not only Italy but the rest of Europe into turbulence.”

Jenni Rivera, Mexican American music star, feared dead in plane crash









Mexican American singer Jenni Rivera, a popular recording artist and reality television star, is feared dead after a small plane crashed early Sunday in northern Mexico. 


Mexico's Ministry of Transportation and Communications said the Learjet carrying seven people, including Rivera, was found in mountainous terrain near Nuevo Leon, just south of Monterrey. There were no survivors, authorities said.

The plane left Monterrey around 3:30 a.m., following a concert that she had given, according to the Associated Press. The U.S.-registered Learjet 25 was headed to Toluca, near Mexico City.







PHOTOS: Jenni Rivera missing

The 43-year-old Long Beach native, known to fans as "la diva de la banda," was best known for her interpretations of regional Mexican music, norteno and banda. She was one of NBCUniversal's biggest bilingual television stars, with a hugely popular reality show, "I Love Jenni," on cable channel Mun2. 


She also had a syndicated weekly radio program and clothing and cosmetics lines -- all designed to appeal to U.S. Latinas. The ABC television network was developing a sitcom starring Rivera, tentatively titled "Jenni," about a strong-willed Latina single mother.


According to Nielsen SoundScan, Rivera has sold 1.2 million albums and 349,000 digital tracks in the United States.


Rivera belonged to one of the most important dynasties in contemporary U.S.-based Mexican music. Her father, Pedro Rivera, launched the independent label Cintas Acuario in 1987; it grew out of a booth at an area swap meet. Her four brothers were also involved in music, and her younger brother Lupillo also is a wildly popular Mexican regional singer.


According to her Telemundo biography, Rivera didn't plan on joining the family's musical dynasty. But after an early marriage ended in divorce, she obtained a college degree in business administration and worked in real estate before going to work for her father's record label.


Her debut, "Chacalosa" (slang for "party girl"), was her introduction to the music scene. She eventually signed with Fonovisa, one of the most prominent labels in regional Mexican music, and began releasing bestselling Latin music CDs.


More than 16,000 people attended a concert that she headlined last year at Staples Center in Los Angeles. She was scheduled to appear next March at L.A.'s Gibson Amphitheatre.


So many fans flocked to a record-signing event in Riverside last year that police reportedly were called to help disperse the massive crowd.


Her tumultuous life included an early marriage and pregnancy, domestic abuse and divorce. She wove some of those themes into her songs and was an advocate for social responsibility. She founded a charitable organization, the Jenni Rivera Love Foundation, offering support to single mothers and victims of domestic abuse in the United States. 


Rivera had five children and a grandchild. Celebrity magazines said she was seeking a divorce from her second husband, former Major League Baseball player Esteban Loaiza.

Bond movie “Skyfall” beats “Lincoln” at box office






(Reuters) – James Bond showed remarkable staying power as the latest installment of the spy series, “Skyfall,” captured the box office title and collected $ 11 million in its fifth week in U.S. and Canadian movie theaters, outgunning Steven Spielberg‘s “Lincoln” and “The Twilight Saga: Breaking Dawn – Part 2,” the final installment of the blockbuster vampire series.


“Skyfall,” the 23rd film in the series featuring Agent 007, also led movies at the box office when it first opened on November 2 and is already the best-selling movie in the 49-year old series. This weekend, it became the highest grossing movie in Sony Pictures‘ history with $ 918 million in ticket sales worldwide. The film distributed by Sony‘s Hollywood studio, has collected nearly $ 262 million in domestic sales, according to the movie tracking site Hollywood.com.






The animated “Rise of the Guardians” from Dreamworks Animation was second with $ 10.5 million in ticket sales. The movie, which was made for $ 145 million, opened with a disappointing $ 23.8 million when it first hit movie theaters on November 21. Since then, it has been steadily working its way toward becoming a solid family hit this season.


“Rise of the Guardians, which features Santa Claus, the Easter Bunny and other childhood favorites who join together to save the world, was one of two family movies in a season traditionally heavy in family films. The other, Disney’s “Wreck-it Ralph,” collected $ 4.9 million for seventh place.


“Breaking Dawn – Part 2,” the box office leader for the past three weeks, tallied $ 9.2 million in ticket sales. The five-movie series, released by Lions Gate Entertainment, is based on Stephenie Meyer‘s best-selling book about young vampire love and has collected more than $ 1.3 billion in overall domestic ticket sales.


“Lincoln,” which chronicles the 16th president’s successful fight to pass a constitutional amendment outlawing slavery, had total ticket sales of $ 9.1 million, according to studio estimates provided by the box office division of Hollywood.com.


“Life of Pi,” director Ang Lee’s movie about a boy who escapes a shipwreck but then shares his lifeboat with a tiger, sold $ 8.3 million in tickets to finish in fifth place. The movie, released by the Fox studio, is based on a best-selling 2001 novel by Yann Martel.


Hollywood studios shied away from scheduling major movies this weekend, steering clear of the expected blockbuster “The Hobbit: An Unexpected Journey,” which Warner Brothers will release on December 14. The movie, based on the J.R.R. Tolkien fantasy novel about wizards and dwarves, features many of the same actors from the blockbuster “The Lord of the Rings” trilogy.


The only new major release, the romantic comedy “Playing for Keeps” starring Gerard Butler and Jessica Biel, opened with a lackluster $ 6 million, which was on target with forecasts by industry experts.

A Breakthrough Against Leukemia Using Altered T-Cells





PHILIPSBURG, Pa. — Emma Whitehead has been bounding around the house lately, practicing somersaults and rugby-style tumbles that make her parents wince.




It is hard to believe, but last spring Emma, then 6, was near death from leukemia. She had relapsed twice after chemotherapy, and doctors had run out of options.


Desperate to save her, her parents sought an experimental treatment at the Children’s Hospital of Philadelphia, one that had never before been tried in a child, or in anyone with the type of leukemia Emma had. The experiment, in April, used a disabled form of the AIDS virus to reprogram Emma’s immune system genetically to kill cancer cells.


The treatment very nearly killed her. But she emerged from it cancer-free, and seven months later is still in complete remission. She is the first child and one of the first humans ever in whom new techniques have achieved a long-sought goal — giving a patient’s own immune system the lasting ability to fight cancer.


Emma had been ill with acute lymphoblastic leukemia since 2010, when she was 5, her parents, Kari and Tom, said. She is their only child.


She is among just a dozen patients with advanced leukemia to have received the experimental treatment, which was developed at the University of Pennsylvania. Similar approaches are also being tried at other centers, including the National Cancer Institute and Memorial Sloan-Kettering Cancer Center in New York.


“Our goal is to have a cure, but we can’t say that word,” said Dr. Carl June, who leads the research team at the University of Pennsylvania. He hopes the new treatment will eventually replace bone-marrow transplantation, an even more arduous, risky and expensive procedure that is now the last hope when other treatments fail in leukemia and related diseases.


Three adults with chronic leukemia treated at the University of Pennsylvania have also had complete remissions, with no signs of disease; two of them have been well for more than two years, said Dr. David Porter. Four adults improved but did not have full remissions, and one was treated too recently to evaluate. A child improved and then relapsed. In two adults, the treatment did not work at all. The Pennsylvania researchers are presenting their results on Sunday and Monday in Atlanta at a meeting of the American Society of Hematology.


Despite the mixed results, cancer experts not involved with the research say it has tremendous promise, because even in this early phase of testing it has worked in seemingly hopeless cases.


“I think this is a major breakthrough,” said Dr. Ivan Borrello, a cancer expert and associate professor of medicine at the Johns Hopkins University School of Medicine.


Dr. John Wagner, director of pediatric blood and marrow transplantation at the University of Minnesota, called the Pennsylvania results “phenomenal,” and said they were “what we’ve all been working and hoping for but not seeing to this extent.”


A major drug company, Novartis, is betting on the Penn team, and has committed $20 million to building a research center on the Penn campus to bring the treatment to market.


HervĂ© Hoppenot, president of Novartis Oncology, called the research “fantastic” and said it had the potential — if the early results hold up — to revolutionize the treatment of leukemia and related blood cancers. Researchers say the same approach, reprogramming the patient’s immune system, may also be used eventually against tumors like breast and prostate cancer.


To perform the treatment, doctors remove millions of the patient’s T-cells — a type of white blood cell — and insert new genes that enable the T-cells to kill cancer cells. The new genes program the T-cells to attack B-cells, a normal part of the immune system that turns malignant in leukemia.


The altered T-cells — called chimeric antigen receptor cells — are then dripped back into the patient’s veins, and if all goes well they multiply like crazy and start destroying the cancer.


The T-cells home in on a protein called CD-19 that is found on the surface of most B-cells, whether they are healthy or malignant.


A sign that the treatment is working is that the patient becomes terribly ill, with raging fevers and chills — a reaction that oncologists call “shake and bake,” Dr. June said. Its medical name is cytokine-release syndrome, or cytokine storm, referring to the natural chemicals that pour out of cells in the immune system as they are being activated, causing fevers and other symptoms. The storm can also flood the lungs and cause perilous drops in blood pressure — effects that nearly killed Emma.


Steroids sometimes ease the reaction, but did not help Emma. Her temperature hit 105. She wound up on a ventilator, unconscious and swollen almost beyond recognition, surrounded by friends and family who had come to say goodbye.


But at the eleventh hour, a battery of blood tests gave the researchers a clue as to what might help save Emma: Her level of one of the cytokines, interleukin-6 or IL-6, had shot up a thousandfold. Doctors had never seen such a spike before and thought it might be what was making her so sick. Dr. June knew that a drug could lower IL-6 — his daughter takes it, for rheumatoid arthritis. It had never been used for a crisis like Emma’s, but there was little to lose. Her oncologist, Dr. Stephan A. Grupp, ordered the drug. The response, he said, was “amazing.”


Within hours, Emma began to stabilize. She woke up a week later, on May 2, the day she turned 7; the intensive-care staff sang “Happy Birthday.”


Since then, the research team has used the same drug, tocilizumab, in several other patients.

Surgeon infected patients during heart procedure, Cedars-Sinai admits









A heart surgeon at Cedars-Sinai Medical Center unwittingly infected five patients during valve replacement surgeries earlier this year, causing four of the patients to need a second operation.


The infections occurred after tiny tears in the latex surgical gloves routinely worn by the doctor allowed bacteria from a skin inflammation on his hand to pass into the patients' hearts, according to the hospital. The patients survived the second operation and are still recovering, hospital officials said.


The outbreak led to investigations by the hospital and both the L.A. County and California departments of public health. The federal Centers for Disease Control and Prevention was also consulted.





Hospital officials called it a "very unusual occurrence" probably caused by an unfortunate confluence of events: the nature of the surgery, the microscopic rips in the gloves and the surgeon's skin condition. Valve replacement requires the surgeon to use thick sutures and tie more than 100 knots, which can cause extra stress on the gloves, they said.


Nevertheless, the hospital's goal is to have zero infections, said Harry Sax, vice chairman of the hospital's department of surgery. "Any hospital-acquired infection is unacceptable," he said.


The infections raise questions about what health conditions should prevent a surgeon from operating and how to get the best protection from surgical gloves. Surgeons with open sores or known infections aren't supposed to operate, but there is no national standard on what to do if they have skin inflammation, said Rekha Murthy, medical director of the hospital's epidemiology department. She added that there were also no national standards on types of gloves used, whether to wear double gloves or how many times surgeons should change those gloves during a procedure.


Healthcare-acquired infections are very common throughout the United States. Each year, infections cause 99,000 deaths in the country, including about 12,000 in California. Hospitals in the state are required to report certain infections to the California Department of Public Health. That reporting makes the public more aware of the quality of care provided at local hospitals and is an important tool for reducing infections, said Debby Rogers, deputy director of the department's Center for Health Care Quality.


Cedars-Sinai has low rates for hospital-acquired infections compared with the state and national average but has not performed as well on other surgical quality measures recently, according to the Leapfrog Group, an employer-backed nonprofit focused on healthcare quality. The organization gave the hospital a C rating last month on its national report card, down from an A in June, though it was not related to the infection outbreak.


"Clearly this hospital is making attempts to reduce infections, but they have more work to do," said Leah Binder, Leapfrog's chief executive.


Cedars-Sinai Medical Center conducts about 360 valve replacement surgeries each year and said infections occur in fewer than 1% of its cases — lower than the national average.


The hospital learned about the problem in June after three patients who had undergone valve replacement surgery showed signs of infection. Doctors diagnosed the patients with an infection called endocarditis. Concerned there might be a connection among the cases, epidemiologists analyzed the bacteria, staphylococcus epidermidis, and determined that it was an identical strain and therefore must have come from a single source. "It led to the question of gee, I wonder where it came from?" Murthy said.


Epidemiologists homed in on the surgeon with the skin inflammation. The bacteria matched, and then they made a surprising discovery: microscopic tears in the gloves typically worn by surgeons after performing valve replacement surgery. The surgeon, whose name was not released, was not allowed to operate again until he healed. He is still a member of the medical staff but no longer performs surgeries at the hospital.


The hospital soon found the same infection in two more patients. Officials also reached out to 67 patients who had heart valve replacements with the same surgeon but didn't find any other cases. One of the five infected patients was treated with antibiotics, and the other four had new valve replacement surgeries. Sax said the hospital apologized to the patients and has continued to monitor their health. The hospital has also covered the cost of their care, including follow-up treatment and all the related surgeries.


All surgeons doing valve replacements are now required to change gloves more frequently, officials said. Some surgeons are wearing double gloves during the operations, Sax said.


Following the outbreak, Cedars-Sinai did the proper follow-up to ensure the safety of their patients, said Dawn Terashita, a medical epidemiologist with L.A. County, who was notified in September. What occurred at Cedars-Sinai was an unintentional consequence of the surgery, she said.


"There is no way to keep a room entirely sterile and all the people in it sterile," she said. "You will always have risk of infection."

James Cameron Relives Voyage to Ocean’s Deepest Spot












SAN FRANCISCO — The first thing James Cameron saw 7 miles below the sea was man-made: tracks from a remotely operated vehicle.


“When I got to the bottom, I saw skid marks from the ROV,” Cameron said yesterday (Dec. 4) here at the annual meeting of the American Geophysical Union, referring to a 2009 survey by the Monterey Bay Aquarium Research Institute. Scientific results of the film director’s expedition to the Mariana Trench were presented at the meeting this week, and Cameron and the researchers described the highlights to a packed crowd.












Cameron reported a new, corrected depth for his landing — 35,803 feet (10,912 meters) — which beats by five feet (1.5 m) the record set by U.S. Navy Lt. Don Walsh and Jacques Piccard in 1960 at the same spot. However, “because the error [calculating the depth] on Don’s dive is much greater, we’re just going to have to call it a tie,” Cameron said.


Deepsea Challenger


Cameron’s Deepsea Challenger expedition made dives to the New Britain Trench and the Mariana Trench in the southwestern Pacific Ocean between Jan. 31 and April 3, with one manned dive by Cameron to the Mariana’s Challenger Deep, the deepest spot in any ocean.


Unusual, never-before-seen species were snared and brought back to the surface. A bizarre microbial mat community was discovered living on altered rocks in the Sirena Deep, another deep pool 6.77 miles (10.9 kilometers) below the surface.


Changes in temperature and salinity starting at 26,200 feet (8 km) deep hint at an unknown current coming into the Challenger Deep, said Doug Bartlett, a microbiology professor at the Scripps Institution of Oceanography at UC San Diego.


The filmmaker journeyed inside a high-tech lime-green machine — a steel sphere encased in foam — dubbed the Deepsea Challenger. The expedition traveled with two unmanned seafloor “landers” — large contraptions hoisted over the side of a ship and dropped to the seafloor. Once on the bottom, bait attached to the lander lured seafloor creatures to the craft, and a suite of instruments took samples, photographs and data. [Images: James Cameron's Historic Deep-Sea Dive]


The two contraptions working together proved to be a very good system, Cameron said. “We could rendezvous on the bottom and see the results of that bait running for six to eight hours, and that’s how Doug could find a new species of giant arthropod,” Cameron said.


Challenging journey


The March 26 dive proved to be a physical and mental challenge for Cameron. “I did yoga for six months so I could contort myself into the sphere,” he said.


As he sank through the water, Cameron said he “burned though my whole checklist,” designed to distract him during the long hours of the dive. “I still had 3,000 meters left to go with pretty much nothing left to do but sit quietly and think about the pressure building up around the hull,” he said.


The sub touched down gently, and Cameron immediately took a sample of the seafloor, as planned. This was a good contingency, because the sub’s hydraulic fluid line then burst, leaving him unable to collect more samples.


To his surprise, the sub’s voice communications worked perfectly. “We actually expected they wouldn’t, and I would have to default to texting,” he said. “Texting while driving is not a good thing, especially if you’re using two hands to operate seven joysticks and you’re 7 miles down.”


Cameron first drove the sub about 200 meters, finding the seafloor elevation stayed the same. In fact, Challenger Deep turned out to be remarkably flat, and the sub was easy to drive. “The vehicle was quite nimble, the sub’s yaw rate was very good,” he said. (Yaw describes the left-to-right rotation of a craft.)


A quick return


After about three hours, some of the submersible’s batteries had low charge readings, the steering was problematic, and it was time to return to the surface. The mission should have lasted five to six hours. “I hate this. I hated having to go back,” Cameron recalled thinking.


The trip to the top was mercifully short at 73 minutes. The submersible covered nearly 7 miles in a little over an hour — slow in a car, but like riding a missile for a human in a metal ball. Cameron said the surface trip is when he noticed the aches and pains from the cramped sub. “That’s when your butt is really sore, and when you notice how much it hurts.” [Infographic: James Cameron's Mariana Trench Dive]


The sub now sits in a barn in Santa Barbara, waiting for Cameron or another group with enough money to send it back to the deep ocean. He declined to say how much it cost to build and mount the expedition.


“I would love for the sub to dive again,” he said. “I personally feel that we just barely got started before we had to turn back and there’s just so much out there.”


“And if not, at the very least, the technical innovations can be incorporated into other vehicle platforms,” Cameron added. “As far as I’m concerned, it’s an open source situation.”

Mick Jagger and Keith Richards to duet on “Letterman” Top 10












LOS ANGELES (TheWrap.com) – Mick Jagger and Keith Richards are no strangers to Top 10 lists, but now they’re poised to expand their knowledge of them beyond the music charts.


Rolling Stones leaders Jagger and Richards will appear on “Late Show With David Letterman” on Tuesday to deliver the Top Ten list for the night, CBS said Friday.












Though this will mark the first time that Jagger and Richards have appeared on “Letterman,” they’ve appeared on the stage of the Ed Sullivan Theater – where “Late Show” is taped – before. The Stones made numerous appearances on “The Ed Sullivan Show,” starting with their maiden performance on October 25, 1964.


The group is currently celebrating its 50th anniversary and recently released the greatest-hits anthology “GRRR!” They be in the area to play the Barclays Center in Brooklyn on Saturday, and at Newark’s Prudential Center on Thursday.


The group will also perform at the Hurricane Sandy benefit concert 12.12.12 – The Concert for Sandy Relief, which takes place Wednesday at Madison Square Garden. Other performers at the benefit will include Paul McCartney, the Who, Bruce Springsteen & the E Street Band, Billy Joel and Eric Clapton, among others.


Letterman has been rubbing shoulders with rock royalty lately – earlier this week, he was joined on his show by the surviving members of Led Zeppelin. Last weekend, Letterman and the group received Kennedy Center Honors.

U.S. now hindered by distance it kept on Syria conflict









WASHINGTON — With the Syrian civil war apparently near a turning point, Obama administration officials are finding their ability to influence the fast-moving events and growing violence hampered by their reluctance to become too deeply involved during the first 21 months of the conflict.


As the opposition has scored major gains against the regime of President Bashar Assad in recent days, U.S. officials have stepped up diplomatic efforts and begun weighing whether to start providing arms or other military assistance to the rebels.


But at a moment when the future of the strategically key nation may be up for grabs, Washington's power is limited by its weak ties to rebel field commanders who will have a major say in what comes next if Assad is toppled, say diplomats, opposition officials and regional experts.





"We don't have a presence on the ground and we haven't given assistance in any measure to these people," said James Jeffrey, a veteran U.S. diplomat who retired last summer after a final posting as U.S. ambassador to Iraq. "This is going to have an impact on our influence ... and it didn't have to be this way."


Though the administration has provided diplomatic pressure, humanitarian relief and nonlethal aid, it has been unwilling to supply arms or to use U.S. military force to set up a no-fly zone, as it did in the Libyan civil war last year. Officials fear that weapons would end up in the hands of extremists, and they want to limit U.S. military involvement at a time when Americans are war-weary and world powers and Arab states are divided on the conflict.


But it has become clear that, as they plan their approach to the next stage of the war, U.S. officials will have to try to overcome the unhappiness of rebel commanders who don't understand America's unwillingness to provide the military help it gave Libyan rebels last year.


The stakes are high. If the regime falls — by no means a certainty — the United States and its allies will want to move quickly to try to steer Syria toward a moderate, multiethnic government and away from a sectarian bloodbath. U.S. officials and allies are now busy formulating plans to help Syrians form a new government.


The number of extremist fighters in groups such as the Al Qaeda-linked Al Nusra Front has been rising, and if those groups take control of a new government, the geopolitical landscape of the region could change overnight in dangerous ways. Obama, who has been criticized by conservatives for failing to do more in Syria, could face accusations that his policy of limited engagement "lost" Syria.


The issue came up in the presidential campaign, with Republican challenger Mitt Romney saying he would supply arms to the Syrian opposition and Obama advocating a more cautious approach.


"We can't simply suggest that giving heavy weapons to the Syrians is a simple proposition that would lead us to be safer over the long term," the president said in the final debate of the campaign.


The rebel commanders' frustration with the United States has been apparent in recent weeks, in demonstrations that in some cases have shown up on YouTube.


One video shows a Nov. 30 demonstration in the village of Binish in which rebel fighters brandish their weapons and declare that they are fighting to create an Islamist Syria that would not be led by a Western-backed coalition of opposition groups, the newly formed National Coalition of Syrian Revolutionary and Opposition Forces.


"We will not leave the revolution to the coalition that is a game in the hand of America and serves the American project," one of the fighters says in Arabic. "Oh, Obama, listen and listen!"


Though his views may be more radical than those of most opposition fighters, there is widespread unhappiness that America has not done more.


"Syrians have been looking for U.S. leadership, but unfortunately the United States has chosen not to get involved and people here have gotten more and more upset," said Khalid Saleh, an executive board member of the Syrian National Council opposition bloc and a representative to the new coalition. He said he believes the United States could still take a lead role, but he has not seen signs that the administration wants to do so.


He noted that whereas France and Britain have recognized the new coalition as the legitimate government-in-waiting in Syria, the United States has been reluctant to do the same — a sign, in his view, that Washington still wants others to lead the way. U.S. officials are expected to formally recognize the group Wednesday at an international meeting on Syria in Marrakech, Morocco.


Dan Layman, an official with the Syrian Support Group, a Washington-based organization that sends nonlethal supplies to the opposition, said he understands the U.S. reluctance to send arms that could end up in the hands of extremists. But he said some Syrian commanders have complained that they have felt compelled to affiliate themselves with militant groups because those groups have access to weapons that are not being supplied by the West.


"We're concerned that some of these commanders may be moving to the wrong side of the street out of necessity," said Layman, whose group is licensed by the U.S. government and funded mostly by Syrian Americans.


U.S. officials have limited their ties to the rebels since the beginning of the conflict, when they urged demonstrators not to turn to arms.


Though they are in regular contact with military councils — provincial bodies that try to coordinate the patchwork of militias — relationships are not strong with individual groups, said Andrew Tabler, a leading Syria expert at the Washington Institute for Near East Policy. The United States could have built a valuable relationship, for example, with Al Farouq brigade, a nationalist but mainline group, he said.


Though the new coalition has been praised in the West for its inclusiveness and leadership, diplomats acknowledge that it's not clear whether the umbrella group would be strong enough to issue orders to the militias that could hold the most power in a post-Assad Syria.


One unsettling possibility is that Syria could be filled with militias that retain their weapons, as in postrevolutionary Libya, but without goodwill toward the United States or loyalty to a transitional government.


"You could have dozens of militias, battle-tested and brimming with weapons, that don't necessarily consider the authorities in Damascus to be sovereign," said David Schenker, a Pentagon official in the George W. Bush administration who is now with the Washington Institute for Near East Policy.
