Route 66 still holds allure for travelers, industry

Route 66 hasn't been a real highway for almost three decades.

The last section of the fabled U.S. route from Chicago to Santa Monica, Calif., was dropped as a federal highway in 1984. But its hold on travelers' imaginations has revived motels, diners, souvenir shops, gas stations and other buildings along the old route.

The enduring fascination, along with some federal grants, has helped Route 66 thrive, even as people old enough to remember its heyday die off.

"People are looking to see the real America, not Walt Disney's version," said Ron Hart, director and founder of the Route 66 Chamber of Commerce in Carthage, Mo.

A Rutgers University study released in March estimated that people spend $132 million annually along old Route 66, which crosses eight states and is marked in some places by ceremonial signs.

Visitors encounter attractions like the Boots Motel, which Hart, as property manager, restored to its late 1940s glory ahead of its re-opening last month.

Built in 1939 and once visited by actor Clark Gable and singer Gene Autry, the Boots had fallen into disrepair and become a flophouse for drug addicts and illegal immigrants, Hart said.

Under its new owners, five rooms have been renovated and more are set to be redone. Guests are treated to touches such as real keys, chrome light fixtures, chenille bedspreads, monogrammed towels, built-in dressers and an old radio tuned to a station that plays 1940s hits. No TVs in the rooms -- just a non-working late 1940s model in the lobby. If you want ice, the staff brings it to your room.

"We sit in front of the motel every night and wave to the people driving by," said Deborah Harvey, a historic preservationist and co-owner of the Boots. "People stop, pull up a chair and tell us their stories about the motel."

Route 66 was completed in the mid-1920s and gained fame in the 1930s when it was described in the John Steinbeck novel "The Grapes of Wrath" as the "mother road" from the Dust Bowl to the promise of California. It later became the family vacation route to the Southwest and was romanticized in movies, music and on television.

"It wasn't the only highway, or the first or the longest, but through the quirks of pop culture it became famous," said Mark Spangler, curator of the Route 66 Museum in Lebanon, Mo.

Tough navigation

The biggest challenge to modern-day Route 66 travelers is staying on the original route, said David Knudson, founder and executive director of the non-profit National Historic Route 66 Federation. Signs are inconsistent along the long route and many are stolen for souvenirs, he said.

"It's hard to follow without a good map," said Knudson, whose group publishes a Route 66 map and guides. "Some parts of the road have deteriorated, some are in good shape and some parts were removed years ago and replaced with cornfields. About 80 percent of the original route is still drivable."

The federal government no longer maintains any of the route, so repairs are done by various cities, counties and states that took over each section, Knudson said. His federation has a program that recruits people to monitor the condition of 100-mile stretches of the road.

But federal funds are available to owners of Route 66 businesses. The National Park Service's Route 66 Corridor Preservation Program has paid an average of $150,000 annually since 2001 for business renovations along the road that are matched privately, according to the Rutgers study.

The survey found that the most popular sights along Route 66 are the old roadside diners, motels, gas stations, souvenir shops, theaters and other businesses. According to the study, 230 buildings along the route are on the National Register of Historic Places.

The route includes quirky sights like the Cadillac Ranch near Amarillo, Texas, which features a series of half-buried Cadillacs with their fins up. In Catoosa, Okla., there is a giant open-mouthed whale built over a popular Route 66 swimming hole.

People also travel Route 66 for the scenery of plains, mountains and rivers, Knudson said. It is still the American definition of the open road, especially as it passes through the remote southwestern states, he said.

"It's the adventure that draws many people," Knudson said. "There is certainly a lot to be said about that."

Egypt votes for 2nd day to pick Mubarak successor

CAIRO (AP) ? Egyptians voted for a second day Sunday in a presidential runoff pitting Hosni Mubarak's last prime minister against a conservative Islamist, with a sense of gloom hanging over many at the polls over the choice and the prospect that the ruling military will still hold most power even after their nominal handover of authority to civilians by July 1.

In a sign of how much power they wield, the military generals were preparing to define the next president's authorities in an interim constitutional declaration that state media said could come by Monday. Under the declaration, the council of generals would be the nation's legislators and control the budget after the Islamist-dominated parliament was dissolved under a court order last week.

The generals will also likely take on the parliament's task of appointing a 100-member assembly to write the permanent constitution, giving them enormous influence over the document that will shape Egypt's future and allowing the opportunity to enshrine for themselves a political say.

As a result, for some voters even as they stood in sweltering heat at the polls, it seemed that the choice for Mubarak's successor ? between Ahmed Shafiq, a longtime friend and admirer of Mubarak, and Mohammed Morsi, the candidate of the fundamentalist Muslim Brotherhood ? would ultimately make little difference.

"I don't trust the whole thing. I feel everything is planned in advance and what we are doing now is just part of the plan," Asmaa Fadil, a young woman who wears the Muslim veil, said at a polling station in the Cairo district of Sayeda Zeinab. She said she had lost confidence in the political process, particularly after the dissolution of parliament.

After the first day of voting ended Saturday, the Brotherhood sought to rally the public behind it, saying that a Morsi win for the presidency was now the only hope for the revolution after the military's consolidation of power.

In a statement issued late Saturday after a meeting of its top leaders, the Brotherhood denounced Thursday's court ruling dissolving parliament, saying it "amounted to a coup against the entire democratic process parliament and takes us back to square one." The fundamentalist group led the now-dissolved parliament with just under half its seats.

It also criticized new powers that were given to military police and intelligence last week to arrest civilians for a host of crimes ? as minor as blocking traffic. The powers will "recreate the climate of terror and oppression and crush the people's hope for change."

Shafiq is a former air force commander and a veteran of Mubarak's governments, so he is closely tied to the military. If he wins, that would likely mean a smooth relationship with the generals. His critics fear it will mean more than that ? the outright continuation of the Mubarak-style, military-backed autocracy that last year's revolt sought to uproot.

Morsi ? and the Muslim Brotherhood ? would likely have far rockier relationship with the generals and a Morsi win could bring a tussle over spheres of power. However, the Brotherhood has reached accommodations with the generals previously since Mubarak's fall on Feb. 11, 2011, just as it struck deals in the past with Mubarak's regime itself.

The winner in the race will be officially announced Thursday. But the result could be known by as early as Monday morning, based on results from individual counting stations that Egyptian media and each campaign usually compile and make public.

Turnout from the two-day balloting, which ends Sunday evening, could be a significant measure. If significantly lower than the 46 percent in last month's first round of the presidential election, it would be a sign of widespread discontent with the choice and doubts over the vote's legitimacy. There were no figures yet from the current voting.

The race between Shafiq and Morsi has deeply polarized the country. Each has a core of diehard supporters. Each won about a quarter of the vote in the presidential election's first round last month in which 13 candidates were running.

But among their critics, each ? or both ? inspire a powerful enmity. The anti-Shafiq camp sees his very candidacy as an insult to the 18-day wave of unprecedented protests last year that ousted Mubarak. The anti-Morsi camp is convinced he will hand the country over to the Brotherhood to turn it into an Islamic state or that the group is just as authoritarian as Mubarak was.

"I am bitter and I am filled with regret that I have to choose between two people I hate. I have to pick a bad candidate only to avoid the worse of the two," lamented a silver-haired pensioner in Cairo's crowded Bab el-Shariyah district. He refused to give his name, fearing retribution for speaking so openly.

"Nothing is going to be resolved and Egypt will not see stability," he added.

A similarly pessimistic note was echoed by another voter, accountant Yasser Gad, 45. "The country is heading to a disaster. It will keep boiling until it explodes. No one in the country wants the former regime to rule us again."

Few voters displayed an air of celebration visible in previous post-Mubarak elections. The prevailing mood was one of deep anxiety over the future ? tinged with bitterness that their "revolution" had stalled, fears that no matter who wins, street protests will erupt again, or deep suspicion that the political system was being manipulated. Moreover, there was a sense of voting fatigue.

Egyptians have gone to the polls multiple times since Mubarak's fall on Feb. 11, 2011 ? a referendum early last year, then three months of multi-round parliamentary elections that began in November, and the first round of presidential elections last month.

"It's a farce. I crossed out the names of the two candidates on my ballot paper and wrote 'the revolution continues'," said architect Ahmed Saad el-Deen, in Cairo's Sayedah Zeinab district, a middle-class area that is home to the shrine of a revered Muslim saint.

"I can't vote for the one who killed my brother or the second one who danced on his dead body," he said, alluding to Shafiq's alleged role in the killing of protesters during last year's uprising and claims by revolutionaries that Morsi's Brotherhood rode the uprising to realize its own political goals.

America Awaits Supreme Court's Ruling on Health Care Reform

MONDAY, June 18 (HealthDay News) -- The U.S. Supreme Court will soon decide the fate of the most consequential piece of health legislation since the enactment of Medicare and Medicaid nearly a half-century ago.

The court is expected to hand down its ruling on the constitutionality of the Patient Protection and Affordable Care Act, the Obama administration's signature legislative achievement, sometime in late June.

The law set in motion a series of reforms designed to extend health coverage to more than 30 million uninsured Americans. It seeks to accomplish these goals in several ways. More lower-income people will be allowed to enroll in Medicaid, while other uninsured individuals can buy coverage through new state health insurance exchanges. Some people who buy coverage may qualify for tax credits.

The 2010 law's most controversial component -- and one of the key targets of the Supreme Court's scrutiny -- requires almost all Americans to maintain health insurance coverage or pay a penalty.

The law also aims to improve the quality and efficiency of health care. For example, there are programs to improve care coordination and reduce fraud and abuse in Medicare, the government-run insurance program for older and disabled Americans.

A number of the law's most popular provisions are already in effect. For instance, parents in private insurance plans that offer dependent coverage can keep their adult children on the plan up to age 26. And most plans must cover preventive health screenings, such as mammograms and colonoscopies, at no out-of-pocket cost to the patient.

Core elements of the law -- such as expanding Medicaid, establishing the state health insurance exchanges and requiring people to have coverage or pay a penalty, known as the "individual mandate" -- aren't scheduled to take effect until 2014.

The high court could decide to uphold the law in its entirety, strike it down entirely, strip away key provisions, or delay a decision until after penalties for not having insurance are assessed. No matter how it rules, there's no sign that the torrid debate over the cost and delivery of health care in the United States will be put to rest.

A recent Harris Interactive/HealthDay poll found, for example, that most Americans agree that changes are needed to sustain Medicare, but few want to pay higher taxes or spend more out of their own wallets to prop up the financially ailing program.

"I think it's a safe bet that the health-care cost debate is going to persist," said Ilya Somin, an associate professor at George Mason University School of Law in Arlington, Va., who has written legal briefs challenging the individual mandate.

The crux of the court challenge

One of the key questions that the Supreme Court is being asked to address is whether the individual mandate is constitutional. Opponents of the provision, set to take effect in 2014, argue that Congress cannot force people to buy health insurance or tax them for failing to pay the penalty.

Another point of contention is whether the law can survive without the individual mandate. New protections in the Affordable Care Act ban insurers from denying anyone coverage because of pre-existing medical conditions or from inflating premiums based on a person's medical history. But architects of law insist that it would be too costly to implement these reforms if only the sick bought insurance.

"Without that requirement, there's an incentive for people to wait and purchase coverage only after they need medical service," said Robert Zirkelbach, a spokesman for America's Health Insurance Plans, a Washington, D.C.-based trade association representing the health insurance industry.

Also at issue is the constitutionality of the law's Medicaid expansion. States, in exchange for additional federal funding, must cover nearly all non-Medicare-eligible adults at or below 133 percent of the federal poverty level. In 2012, the cutoffs are $14,856 for an individual and $30,657 for a family of four.

In the two years since its passage, the Affordable Care Act has been the target of multiple lawsuits, with a handful of cases working their way through the federal appellate court system.

In previous cases, the 6th Circuit Court of Appeals in Cincinnati and the D.C. Circuit Court of Appeals in Washington upheld the individual mandate. But the courts have not ruled in lockstep. The 11th Circuit in Atlanta found the mandate unconstitutional but allowed the rest of the law, including the Medicaid expansion, to stand.

Last November, the U.S. Supreme Court agreed to hear arguments from two 11th Circuit cases filed by the National Federation of Independent Business and a 26-state coalition led by the State of Florida.

In March, the high court heard oral arguments on the Medicaid expansion and the individual mandate as well as the mandate's severability from the rest of the law. It also considered whether the fine for not buying insurance is a "penalty" or a "tax." That distinction is important because federal law bars the court from ruling on a tax dispute before the tax is levied.

Predicting the outcome

Constitutional law experts who followed proceedings in the case believe that Justice Anthony Kennedy, a moderate Reagan-era appointee, may hold the deciding vote. On Day 2 of oral arguments in March, Kennedy said the federal government has "a heavy burden" to justify Congress' right to mandate health insurance coverage. Yet he also seemed to acknowledge the government's view that health insurance is different from other markets. Chief Justice John Roberts, another Republican appointee, also posed questions that seemed to both bolster and undercut the government's position.

"I think that there's a strong possibility that the court will uphold the entire law, 6 to 3, with Kennedy and Roberts voting to uphold it," said law professor Ren?e Landers, director of Suffolk University Law School's Health and Biomedical Law Concentration, in Boston.

She found both justices' questions "quite balanced" and believes "both of them have this institutional concern for the court about wiping out in one fell swoop 70-plus years of jurisprudence on the Commerce Clause," the section of the Constitution that gives Congress the power to regulate activities that affect interstate commerce.

"If the law is invalidated in any respect, it'll be a 5-4 decision, clearly along Republican-appointee, Democratic-appointee lines," Landers added.

At Intrade, an online financial exchange for wagering on political, entertainment and financial events, investors are predicting the individual mandate has a better than 57 percent chance of being ruled unconstitutional by the court before year's end, and a 61 percent chance of its demise before the end of 2013.

George Mason's Somin doesn't believe the federal government's arguments in defense of the mandate stand up to scrutiny. "When you look at each one of them closely, they all break down against inspection," he said.

What it means for patient care

Striking down the health reform law would end health insurance coverage for millions of Americans, disrupt efforts to improve care coordination and halt important insurance market reforms, among other reforms, according to the American Medical Association.

"We continue to support the health reform law as an important step in transforming our health-care system, although we are working hard to improve and make important changes in the law," AMA President-elect Dr. Jeremy Lazarus said in a prepared statement.

Added Michael Miller, policy director at Boston-based Community Catalyst, a national consumer advocacy group: "The implications for patients . . . and for the health-care system are catastrophic."

Miller cited a Robert Wood Johnson Foundation-funded study published in the journal Medical Care that suggested that high rates of "uninsurance" in a community have a "spillover effect," negatively influencing working-age adults' and seniors' access to health-care services and satisfaction with the care they receive.

A majority of working-age adults and children in America -- 53.5 percent in 2010, according to a study by the National Institute for Health Care Reform -- have coverage through an employer-sponsored health plan.

Tracy Watts, a senior consultant in the Washington, D.C., office of the consulting firm Mercer LLC, said people in employer-sponsored plans can expect to see continuing efforts to replace traditional coverage with so-called consumer-directed plans, which pair a high-deductible plan with some type of savings account. There will also be greater use of incentives for individuals to stay healthy and manage chronic conditions, and higher out-of-pocket costs, she said.

"With or without reform, employers are focused on how to manage costs," Watts said.

"ObamaCare" opponents, however, suggest that the public would be better off if the Supreme Court were to invalidate the entire law.

"One of the criticisms that has been leveled at people who say this [law] should go down is, 'Well, we don't want to go back to the way it was,' and we agree 100 percent that the way it was prior to the passage of this law was not working," said Dr. Richard Armstrong, a general surgeon in Newberry, Mich., and chief operating officer of Docs4PatientCare, whose members oppose the Affordable Care Act.

Instead, the organization backs a series of free-market reforms that would put health-care spending decisions back in consumers' hands.

"The bottom line in this is that we need to get back to some fiscal sanity in America," Armstrong said.

Loneliness in older individuals linked to functional decline, death

ScienceDaily (June 18, 2012) ? Loneliness in individuals over 60 years of age appears associated with increased risk of functional decline and death, according to a report published Online First by Archives of Internal Medicine, a JAMA Network publication.

In older persons, loneliness can be a common source of distress and impaired quality life, according to the study background.

Carla M. Perissinotto, M.D., M.H.S., of the University of California, San Francisco, and colleagues examined the relationship between loneliness and risk of functional decline and death in older individuals in a study of 1,604 participants in the Health and Retirement Study.

The participants (average age 71) were asked if they felt left out, isolated or a lack of companionship. Of the participants, 43.2 percent reported feeling lonely, which was defined as reporting one of the loneliness items at least some of the time, according to the study results.

Loneliness was associated with an increased risk of death over the six-year follow-up period (22.8 percent vs. 14.2 percent), the results indicate. Loneliness also was associated with functional decline, including participants being more likely to experience decline in activities of daily living (24.8 percent vs. 12.5 percent), develop difficulties with upper extremity tasks (41.5 percent vs. 28.3 percent) and difficulty in stair climbing (40.8 percent vs. 27.9 percent).

"Loneliness is a common source of suffering in older persons. We demonstrated that it is also a risk factor for poor health outcomes including death and multiple measures of functional decline," the authors comment.

The authors conclude their study could have important public health implications.

"Assessment of loneliness is not routine in clinical practice and it may be viewed as beyond the scope of medical practice. However, loneliness may be as an important of a predictor of adverse health outcomes as many traditional medical risk factors," the researchers note. "Our results suggest that questioning older persons about loneliness may be a useful way of identifying elderly persons at risk of disability and poor health outcomes."

Invited Commentary: What are We Really Measuring?

In an invited commentary, Emily M. Bucholz, M.P.H., and Harlan M. Krumholz, M.D., S.M., of the Yale University School of Medicine, New Haven, Conn., write: "Social support -- few concepts in epidemiology have proven more elusive to define."

"As we look forward to future studies on social support, the importance of clarifying the mechanisms by which this amorphous concept influences health becomes clear," they continue.

"Loneliness is a negative feeling that would be worth addressing even if the condition had no health implications. Nevertheless, with regard to health implications, scientists examining social support should build on studies such as those published in this issue and be challenged to investigate mechanisms as well as practical interventions that can be used to address the social factors that undermine health," the authors conclude.

China to US embassy: Stop telling people how bad the air is in Beijing.

Air quality in Beijing is notorious for being 'crazy bad.' The US Embassy in Beijing started tweeting air quality reports, but now China says it's unfair to judge it by international standards.

By Peter Ford,?Staff writer / June 5, 2012

A cleaner wears a face mask as she works in front of the giant portrait of former Chinese chairman Mao Zedong at Beijing's Tiananmen Gate on June 5. The Chinese government today warned the US Embassy in Beijing to stop telling the world how bad the air quality really is.

The Chinese government today warned the US Embassy in Beijing to stop telling the world just how bad the capital?s air really is.

For the past three years or so, the embassy has Tweeted the hourly readings from a pollution monitor on its roof, providing the only real time indicator of what we are breathing here.

Deputy Environment Minister Wu Xiaoqing, however, told reporters today that this was a violation of the Vienna Convention on Diplomatic Relations. Only the Chinese government is allowed to measure and publish air quality information, he said.

The trouble with that is that I am not the only person in Beijing who has sometimes found it hard to reconcile the soupy grey fog that I often see outside my window with the Beijing Municipal Environmental Monitoring Center?s insistence that pollution is ?light.?

The US embassy spokesman was unavailable to comment on Mr. Wu?s admonition, but @BeijingAir, its Twitter feed, was still posting at 6 p.m.; it found the air to be ?Unhealthy for Sensitive Groups.?

That is a definition taken from the US EPA, and Wu said it was not fair to judge Chinese air by American standards, which are stricter than Chinese ones, because of ?our current stage of development.?

This is not the first time the US Twitter feed has got into trouble. On Nov. 19, 2010, when the Air Quality Index soared above 500 ? the top of the US scale ? the reading was described in a tweet as ?crazy bad.?

The term appeared to have been inserted into the monitoring program by a programmer who never expected such an outlandishly high reading: Anything over 300 ?would trigger a health warning of emergency conditions? in America, according to an EPA website.

Nowadays, readings over 500 (20 times higher than World Health Organization guidelines) are described simply as ?beyond index.?

The Beijing municipality website publishes its own hourly readings of PM 2.5 tiny particulate matter, regarded as especially dangerous, but only 24 hours after the fact. It also publishes an average figure for air quality over the previous 24 hours, but does not characterize it as good, bad, or hazardous.

Wu?s warning to the US embassy will doubtless re-focus public attention on the real quality of Beijing?s air, which cannot be good for the authorities. What?s odd is that for the past few early summer days here the air has mostly been clear, and even gloriously sharp on one or two evenings.

If the embassy Twitter feed dies, we shall just have to go back to trusting our eyes and our noses. Just because we cannot put a scientific figure to it, doesn?t mean we don?t know what we are breathing.

Myanmar boat people swap violence for desperation

GOLAR PARA, Bangladesh (Reuters) - At first, the boat bobbing in the water in the middle of the night appeared to be empty. But when Bangladeshi villagers took a closer look, they found a baby too weak to cry, a refugee from marauding mobs in Myanmar apparently abandoned by her family.

The cleft-lipped infant, just weeks old, is among hundreds of Rohingya Muslims who fled this month's sectarian violence in Myanmar's western state of Rakhine, packing themselves into rough wooden boats and heading for the shores of neighboring Bangladesh.

No one knows how many made it ashore. Bangladesh has ordered its border guards to push the boats back, determined that - with at least quarter of a million "illegal migrants" already here - there must be no more.

The baby, named Fatima by the family that has taken her in, is out of the danger that she and her family faced in Myanmar, but she joins a throng of stateless people in southeast Bangladesh who - for the most part - lead desperate lives of squalor, deprivation and discrimination.

Among them is Mohammad Kamal, a young religious leader from Rakhine's Maungdaw district, where ferocious violence erupted on June 9 between Rohingyas and ethnic Rakhine Buddhists and spread across the state. He escaped to Bangladesh in 2006 after his brother and others were jailed in a crackdown on Muslim clerics.

Kamal, now 28, settled in a makeshift "unregistered" camp, where - along with some 20,000 others - he is not recognized as a refugee and where even international aid agencies have to work under the radar because Bangladesh has not granted them legal status.

"I went out for a walk one day last year and was arrested because I had no documents," said Kamal, pulling up a trouser leg to show a line of angry sores that broke out during the following nine months he spent in jail.

Behind him, naked children play in a muddy pool and the rickety dwellings of an overcrowded shanty town - his camp - rise up, lashed by monsoon rains.

In 2010, the authorities forcibly evicted thousands from a makeshift camp. The medical charity Medecins Sans Frontieres recounted at the time that some Rohingyas had been thrown into the Naf River and told to swim the 3 km (2 miles) back to Myanmar, and the organization said it had treated many for beatings, machete wounds and even rape.

"A DESPERATE LIFE"

Craig Sanders, the U.N. High Commissioner for Refugees' representative in Dhaka, said that although Bangladesh has disowned the Rohingyas - dubbing them illegal economic migrants - it has shown "tremendous generosity over many years".

Rohingyas first came in large numbers to the South Asian nation in 1973, and over the years gained a reputation for drug-smuggling, gun-running and human trafficking.

A sudden flood of more than quarter of a million arrived in 1991-92 after a spasm of repression by the security forces in military-ruled Myanmar. Those that remain from that wave, now numbering some 30,000, live in two official camps where the U.N. provides everything from shelter and water supply to healthcare and schooling.

But at least 200,000 others - probably many more - have settled on the Bangladesh side of the 200-km (125-mile) border, mingling with the population where they struggle to find employment or squeezing into unofficial camps.

It is these "unregistered" Rohingyas who are most vulnerable.

"It's an extremely desperate life for these people," said one worker for a humanitarian group that provides assistance illegally at one camp, asking not to be named. "They have been here for such a long time and there is no prospect of change."

UNHCR's Sanders has crossed swords with the government in recent days over its decision to turn back the boatloads of traumatized Rohingyas.

"Bangladesh, one more time, is being urged to step forward to deal with a situation that is not of their making," he said. "We are not trying to push them into a corner on this issue, but there is a question of fair and right treatment here."

BANGLADESH SAYS "NO MORE"

There have been sketchy and conflicting reports of the communal violence that erupted in Rakhine, but scores are feared dead after widespread torching of houses by both sides.

Abdus Salam, one of 10 Rohingyas who reached Bangladesh and are now hiding in a coastal village to avoid arrest, told Reuters last week: "The Rakhine torched our houses, killed our relatives, assaulted our women. They were killing Muslims. When we protested, the government forces also shot our people dead. Then we started fleeing."

Muhammad Zamir, Dhaka's chief information commissioner, maintains that the authorities have treated the boat people humanely, providing those they turn away with water, medicines and fuel for the journey back, assisting a woman who gave birth on arrival and treating those with gunshot wounds in hospital.

"We want to help the refugees, they have rights," Zamir told Reuters in the coastal town of Cox's Bazar, a bumpy three-hour drive from the shores where Rohingyas are being pushed back.

"But we can only look after them to a point. We really can't handle any more."

He argues that, as a densely populated and poverty-plagued country of 150 million, Bangladesh has played its part. Now, as democracy stirs in Myanmar, it is time for its neighbor to address the root causes of the chronic exodus of Rohingyas, and for the international community to put pressure on it to do so.

SILENT CRISIS

There has been some dismay in this part of Bangladesh at the hard line taken by the government on the new arrivals. The populations share the same ethnicity, religion and dialect, and they are so close that if you call a Rohingya on a mobile phone in Myanmar it is likely to be a Bangladesh number.

Yet the plight of those already here gets little attention.

A report by U.S.-based rights group Refugees International last year described a "silent crisis" of abuse, starvation and detention faced by stateless Rohingyas in Bangladesh.

According to UNHCR, a 2011 survey in the two official camps found that 17 percent of children between six months and six years were suffering from acute malnutrition, higher than the emergency threshold set by the World Health Organisation. In the makeshift camps, malnutrition rates are even higher.

"It's a hopeless situation," said the aid worker. "You treat the children who are sick, and then they fall ill again because they are not getting the right food."

For now at least, tiny Fatima is safe. She has been taken in by a fisherman and his wife who already have four sons and two daughters. But an uncertain future awaits her, stateless in the land of her refuge.

Hot Yankees beat Nats in 14

Teixeira hits two-run double off Lidge to lift New York

The Yankees' Mark Teixeira hits a two-run double in the 14th inning to beat the Nationals.

By JOSEPH WHITE

updated 7:34 p.m. ET June 16, 2012

WASHINGTON - Entering the 14th inning, the New York Yankees were 0 for 14 with runners in scoring position, and Washington Nationals teen sensation was Bryce Harper was 0 for 6 at the plate.

The Yankees got off their goose egg. Harper didn't.

Mark Teixeira's two-run double to the right-field corner made the difference Saturday as the Yankees won their eighth straight game, beating the Nationals 5-3.

New York outfielder Dewayne Wise, who cut down a runner at the plate in the eighth inning to keep the game tied, said it felt as if the game "was going to go 25 innings. I was looking at the bullpen thinking I may have to come in and throw an inning or two."

Jayson Nix opened the 14th with an infield single, then stole second and advanced to third on Derek Jeter's single to left. Jeter's hit made the Yankees 1 for 15 with runners in scoring position, but Nix couldn't score because he had to make sure the ball made it past the infield.

After Curtis Granderson struck out, Teixeira got the Yankees up to 2 for 16 with the double off Brad Lidge (0-1). It was Teixeira's only hit on a day that started - seemingly long ago - with strikeouts in the first, third and fifth innings.

"Find a way to get it done, and that's what our guys did," manager Joe Girardi said. "To be honest, I was having a hard time remembering how we got our other three runs. It was so long ago."

Freddy Garcia (1-2) pitched two innings to get the win.

Rafael Soriano earned his 12th save, but only after allowing consecutive one-out singles to Jesus Flores and Steve Lombardozzi. The game ended when Soriano got Harper to ground out, ending the rookie's 0-for-7 day that included five strikeouts.

"I thought he was really amped up," Washington manager Davey Johnson said. "I've never seen him swing at balls out of the zone. He was chasing balls. He got into that mode of trying to make something happen."

One day after turning 40, Andy Pettitte allowed two runs and five hits over seven innings in his Nationals Park debut. He particularly embarrassed Harper by getting the 19-year-old to strike out three times lunging at off-speed pitches in the lefty-vs.-lefty, old-vs.-young matchup.

Harper laid off the off-speed pitches his fourth time up against Pettitte and hit a fastball deep to left-center with a man on the seventh inning, but Granderson made a running two-out catch that temporarily preserved the Yankees' lead. Harper also was called out on strikes in the 10th against lefty Clay Rapada and went down swinging in the 13th against righty Garcia.

Harper declined to speak to reporters after the game, but he was the talk of the Yankees clubhouse. Despite the kid's tough day, Girardi was concerned about a storybook ending when Harper came up in the 14th.

"You start thinking, `OK, this guy's has a really tough day, and people are cheering for him, and it could just change his whole day,"' Girardi said.

But it didn't. The Yankees won for the 18th time in 21 games. The only thing missing was the requisite home run: New York won for the first time all season without hitting a homer, ending an 0-12 streak.

Ian Desmond hit a solo homer in the Washington eighth off Cory Wade that made it 3-all. The Nationals had a chance to take the lead later in the inning when pinch-hitter Adam LaRoche singled to right with Tyler Moore on second.

Wise, who had just moved to right field from left field in a double switch for LaRoche's at-bat, charged the ball and threw out Moore on a close play at home. Replays appeared to show that Moore's hand slapped the plate just ahead of catcher Russell Martin's tag.

"I don't want to say it, but, you know, I made a good throw," Wise said with a laugh. "The umpire says he was out, so that kept us going. That's the main thing - you make it close, you never know what might happen."

With Alex Rodriguez taking the day off from the starting lineup, Eric Chavez started at third and reached base four times, including a double off the scoreboard in right-center that gave the Yankees a 3-2 lead in the sixth.

Washington starter Jordan Zimmermann allowed three runs and five hits over six innings.

Notes: Pettitte set a major league record by starting his 52nd interleague game, passing Livan Hernandez. He is 19-16 in AL vs. NL matchups. ... Rodriguez appeared as a pinch hitter in the 10th inning and grounded out to second base. ... The Roger Clemens trial is taking place a dozen blocks or so from Nationals Park, but it's hardly the talk of the clubhouse. "I follow it, but I just wish it wasn't in the news," Nationals manager Davey Johnson said. "I just wish that we could get by that. He was a great pitcher. He's got a lot of my respect, and I hate to see any negative light shed on baseball in any way, and on any of the great players." ... Yankees OF Nick Swisher left the game with a bruised quad.
