Well: Weight Loss Surgery May Not Combat Diabetes Long-Term

Weight loss surgery, which in recent years has been seen as an increasingly attractive option for treating Type 2 diabetes, may not be as effective against the disease as it was initially thought to be, according to a new report. The study found that many obese Type 2 diabetics who undergo gastric bypass surgery do not experience a remission of their disease, and of those that do, about a third redevelop diabetes within five years of their operation.

The findings contrast with the growing perception that surgery is essentially a cure for Type II diabetes. Earlier this year, two widely publicized studies reported that surgery worked better than drugs, diet and exercise in causing a remission of Type 2 diabetes in overweight people whose blood sugar was out of control, leading some experts to call for greater use of surgery in treating the disease. But the studies were small and relatively short, lasting under two years.

The latest study, published in the journal Obesity Surgery, tracked thousands of diabetics who had gastric bypass surgery for more than a decade. It found that many people whose diabetes at first went away were likely to have it return. While weight regain is a common problem among those who undergo bariatric surgery, regaining lost weight did not appear to be the cause of diabetes relapse. Instead, the study found that people whose diabetes was most severe or in its later stages when they had surgery were more likely to have a relapse, regardless of whether they regained weight.

“Some people are under the impression that you have surgery and you’re cured,” said Dr. Vivian Fonseca, the president for medicine and science for the American Diabetes Association, who was not involved in the study. “There have been a lot of claims about how wonderful surgery is for diabetes, and I think this offers a more realistic picture.”

The findings suggest that weight loss surgery may be most effective for treating diabetes in those whose disease is not very advanced. “What we’re learning is that not all diabetic patients do as well as others,” said Dr. David E. Arterburn, the lead author of the study and an associate investigator at the Group Health Research Institute in Seattle. “Those who are early in diabetes seem to do the best, which makes a case for potentially earlier intervention.”

One of the strengths of the new study was that it involved thousands of patients enrolled in three large health plans in California and Minnesota, allowing detailed tracking over many years. All told, 4,434 adult diabetics were followed between 1995 and 2008. All were obese, and all underwent Roux-en-Y operations, the most popular type of gastric bypass procedure.

After surgery, about 68 percent of patients experienced a complete remission of their diabetes. But within five years, 35 percent of those patients had it return. Taken together, that means that most of the subjects in the study, about 56 percent — a figure that includes those whose disease never remitted — had no long-lasting remission of diabetes after surgery.

The researchers found that three factors were particularly good predictors of who was likely to have a relapse of diabetes. If patients, before surgery, had a relatively long duration of diabetes, had poor control of their blood sugar, or were taking insulin, then they were least likely to benefit from gastric bypass. A patient’s weight, either before or after surgery, was not correlated with their likelihood of remission or relapse.

In Type 2 diabetes, the beta cells that produce insulin in the pancreas tend to wear out as the disease progresses, which may explain why some people benefit less from surgery. “If someone is too far advanced in their diabetes, where their pancreas is frankly toward the latter stages of being able to produce insulin, then even after losing a bunch of weight their body may not be able to produce enough insulin to control their blood sugar,” Dr. Arterburn said.

Nonetheless, he said it might be the case that obese diabetics, even those whose disease is advanced, can still benefit from gastric surgery, at least as far as their quality of life and their risk factors for heart disease and other complications are concerned.

“It’s not a surefire cure for everyone,” he said. “But almost universally, patients lose weight after weight loss surgery, and that in and of itself may have so many health benefits.”

United Is Struggling Two Years After Its Merger With Continental

Nam Y. Huh/Associated Press

A United 787 Dreamliner at O’Hare International Airport in Chicago. United lost $103 million through the third quarter of 2012.

CHICAGO — It was supposed to be a moment for celebration: United Airlines observing the delivery of its second Boeing 787 Dreamliner with a flight from Seattle to Chicago earlier this month for a select group of employees, while senior officers, including Jeffery A. Smisek, United’s hard-charging chief executive, served Champagne and took lunch orders.

Jad Mouawad/The New York Times

Jeff Smisek, the chief of United Airlines, served champagne on a flight to celebrate delivery of a Boeing 787 on Nov. 15.

But before the flight took off that morning, a computer glitch in one of the airline’s computer systems delayed 250 flights around the world for two hours.

So it goes at United these days. The world’s biggest airline, created after United merged with Continental Airlines in 2010, promised an unparalleled global network, with eight major hubs and 5,500 daily flights serving nearly 400 destinations. As an added benefit, the new airline would be led by Mr. Smisek of Continental, which was known for its attention to customer service.

But two years on, United still grapples with a myriad problems in integrating the two airlines. The result has been hobbled operations, angry passengers and soured relations with employees.

The list of United’s troubles this year has been long. Its reservation system failed twice, shutting its Web site, disabling airport kiosks and stranding passengers as flights were delayed or canceled. The day of the 787 flight, another system, which records the aircraft’s weight once passengers and bags are loaded, shut down because of a programming error.

United has the worst operational record among the nation’s top 15 airlines. Its on-time arrival rate in the 12 months through September was just 77.5 percent — six percentage points below the industry average and 10 percentage points lower than Delta Air Lines. It had the highest rate of regularly delayed flights this summer, and generated more customer complaints than all other airlines combined in July, according to the Transportation Department.

The airline even angered the mayor of Houston, Continental’s longtime home and still the carrier’s biggest hub, when it unsuccessfully sought to block Southwest Airlines’ bid to bring international flights to the city’s smaller airport, Hobby. 

The United-Continental merger is weighing on the company’s finances. It took a $60 million charge in the third quarter for merger-related expenses, including repainting planes. It also took a $454 million charge to cover a future cash payment to pilots under a tentative deal reached in August.

While most large airlines reported profits this year, United has lost $103 million in the first three quarters of 2012, with revenue up just 1 percent to $28.5 billion. Its shares are up 7 percent this year compared with a 12 percent gain for the Standard & Poor’s 500-stock index and a 24 percent gain for Delta.

“United remains at a challenging point,” analysts from Barclays wrote last month, and they forecast that the carrier would not begin to see the benefits of its merger until late in 2013 and into 2014. Still, while airlines initially struggle, mergers increase revenue eventually, as the example of Delta’s acquisition of Northwest Airlines demonstrated two years ago.

Mr. Smisek, taking a break from serving coffee halfway through the maiden 787 flight, acknowledged that things were not going as fast as expected, particularly given the aggressive targets he set two years ago. Back then, Mr. Smisek said the merger would be wrapped up in 12 to 18 months. He has since learned to be patient, he said.

“It is still a work in progress,” he said. “The integration of two airlines takes years. It’s very complex. If you look at where we were two years ago, we’ve come a long way.”

Admittedly, the process is complicated. Airline mergers mean combining different technologies, often old computer systems, as well as thousands of procedures used by pilots and flight dispatchers, gate agents, flight attendants and ground crew.

Setbacks are common. Like United, US Airways experienced a breakdown in its booking technology after its combination with America West in 2005. Delta’s on-time performance fell sharply in the year after its purchase of Northwest.

But today, Delta is a leader among big airlines in on-time performance. US Airways had a record third-quarter profit even though it still lacks common work rules for its pilots seven years after its merger.

United has completed many of its merger tasks, particularly as far as passengers are concerned. It has received its single operating certificate from the Federal Aviation Administration, allowing it to run a combined fleet. Despite all the problems this summer, it claims to have finally merged the reservation and technology systems.

Protesters Gather Again in Cairo Streets to Denounce Morsi

CAIRO — Tens of thousands of people filled the central Tahrir Square on Tuesday afternoon in an outpouring of rage at President Mohamed Morsi’s attempt to claim expansive new powers and at the role in politics played by his party, the Muslim Brotherhood.

An attempt by Mr. Morsi on Monday to soften his edict, by reaffirming his deference to Egyptian courts, did little to constrain the crowd, which some estimates put at hundreds of thousands of people. In scenes that were reminiscent of the popular uprising against President Hosni Mubarak, and that signaled the country’s current widening divides, the protesters dusted off old taunts for Mr. Morsi, the country’s first freely elected leader.

“Leave,” they chanted. “The people want the fall of the regime.”

The president’s opponents turned out large numbers in several other cities, and clashed at times with his supporters, including in Mahalla el-Kubra in the Nile Delta, where more than a hundred people were reportedly injured. The Brotherhood also reported attacks on several of its political offices.

Most significant, though, was the turnout in Tahrir Square, where Egypt’s secular-minded opposition appeared to have momentarily overcome its divisions, bolstering its numbers with new allies among people implacably opposed to the Brotherhood, in an effort to muster a serious, visible challenge to Egypt’s Islamist groups.

It remained unclear whether Tuesday’s numbers signaled a new movement, or a moment. Islamists have repeatedly won at the polls since the fall of Mr. Mubarak, and the Brotherhood has shown its ability to turn out large crowds with little difficulty.

On Tuesday, the Brotherhood mocked the gathering in Tahrir Square, dismissing the protesters as “remnants” of the Mubarak government on a television channel associated with the group and playing down their numbers on Twitter.

The taunts were ignored in Tahrir Square, where the crowd chanted, “The square is full without the Brotherhood.”

The gathering was prompted by an edict released by Mr. Morsi last week that his decisions would be above judicial review, a move that essentially removed the last check on his power, since Egypt’s Parliament had earlier been dissolved by the courts.

Though Mr. Morsi framed the decree as an attempt to insulate Egypt’s constitutional assembly from being dissolved by Mubarak-era judges, it was quickly attacked as a power grab and a worrying return to autocracy. On Monday, through his spokesman, Mr. Morsi again tried to explain his intentions, saying he would work within judicial precedents to hold back efforts to dissolve the constituent assembly, rather than putting his power above judicial scrutiny.

Even as Mr. Morsi tried to placate the country’s judges, Egyptian television on Monday showed the growing polarization of the country in split-screen coverage of two funerals, each for a teenage boy killed in clashes set off by Mr. Morsi’s edict.

“Now blood has been spilled by political factions, so this is not going to go away,” said Rabab el-Mahdi, an activist and professor at the American University in Cairo, adding that these were the first deaths that rival factions had blamed on one another and not on the Mubarak government’s security forces since uprising began last year.

Despite Mr. Morsi’s attempts at clarification, opposition leaders went ahead with Tuesday’s protest. Some said that respect for the judiciary was now only a small part of their cause, and that their goal was to abort the current Islamist-dominated constituent assembly.

Many protesters treated the occasion as a referendum on Mr. Morsi’s rule, saying he and his prime minister had failed to make important changes, like reforming the Interior Ministry.

“I voted for Mr. Morsi,” said Emad Abdel Kawy, 35, a computer engineer. “It seems like he doesn’t know what he’s doing. You expect a revolution to bring revolutionary actions. It didn’t happen.” And like many here, Mr. Abdel Kawy blamed the Brotherhood, which Mr. Morsi helped lead before becoming president.

“It’s clear he doesn’t make the decisions,” he said of Mr. Morsi. “The decisions come to him.”

The gathering brought together the revolution’s hardened activists with their former foes, including supporters of the Mubarak government. Some said that the strange new alliances were just a necessary result of Egypt’s confusing, emerging politics. Yosra Mostafa, a 28-year-old activist, said she realized that some of Mr. Mubarak’s supporters had turned out simply because they sought a return to power.

“I don’t mind being on their side to oust a dictator,” she said, speaking of Mr. Morsi.

The show of unity masked deep divisions between the opposition and other groups and even in them, Ms. Mahdi said.

“This is not a united front, and I am inside it,” she said. “Every single political group in the country is now divided over this. Is the decree revolutionary justice or building a new dictatorship? Should we align ourselves with felool” — the term for the remnants of the old government — “or should we be revolutionary purists?”

Yasser el-Shimy, an Egypt analyst at the International Crisis Group, argued that the persistence of protests against Mr. Morsi reflected in part the failure of the opposition to accept its own recent election defeats, including of the parliamentary and presidential elections.

“It has never come to terms with these defeats, so it tries to delegitimize the Muslim Brotherhood,” he said.

Dark Warnings About Future of Internet Access

PARIS — A commercial and ideological clash is set for next week, when representatives of more than 190 governments, along with telecommunications companies and Internet groups, gather in Dubai for a once-in-a-generation meeting.

The subject: Control of the Internet, politically and commercially.

The stated purpose of the World Conference on International Telecommunications is to update a global treaty on technical standards needed to, say, connect a telephone call from Tokyo to Timbuktu. The previous conference took place in 1988, when the Internet was in its infancy and telecommunications remained a highly regulated, mostly analog-technology business.

Now the Internet is the backbone for worldwide communications and commerce. Critics of the International Telecommunication Union, the agency of the United Nations that is organizing the meeting, see a dark agenda in the meeting. The blogosphere has been raging over supposed plans led by Russia to snatch control of the Internet and hand it to the U.N. agency.

That seems unlikely. Any such move would require an international consensus, and opposition is widespread.

Terry D. Kramer, the former Vodafone executive who is the United States ambassador to the conference, has vowed to veto any change in how the Internet is overseen.

Analysts say the real business of the conference is business. “The far bigger issue — largely obscured by this discussion — are proposals that are more likely to succeed that envision changing the way we pay for Internet services,” Michael Geist, an Internet law professor at the University of Ottawa, said by e-mail.

Hamadoun Touré, secretary general of the I.T.U., has repeatedly said that the U.N. group has no desire to take over the Internet or to stifle its growth. On the contrary, he says, one of the main objectives of the conference is to spread Internet access to more of the four and a half billion people around the world who still do not use it.

And yet, groups as diverse as Google, the Internet Society, the International Trade Union Confederation and Greenpeace warn that the discussions could set a bad precedent, encouraging governments to step up censorship or take other actions that would threaten the integrity of the Internet.

“This is a very important moment in the history of the Internet, because this conference may introduce practices that are inimical to its continued growth and openness,” Vinton G. Cerf, vice president and chief Internet evangelist at Google, said in a conference call.

Google set up a Web site last week, “Take Action,” encouraging visitors to sign a petition for a “free and open Internet.” The campaign is modeled on the successful drive last winter to defeat legislative proposals to crack down on Internet piracy in the United States.

More energy is expected to be spent on how companies make money off the Internet. In one submission to the conference, the European Telecommunications Network Operators’ Association, a lobbying group based in Brussels that represents companies like France Télécom, Deutsche Telekom and Telecom Italia, proposed that network operators be permitted to assess charges for content providers like Internet video companies that use a lot of bandwidth.

Analysts say the proposal is an acknowledgment by European telecommunications companies that they cannot hope to provide digital content. “The telecoms realize that they have lost the battle,” said Paul Budde, an independent telecommunications analyst in Australia. “They are saying, ‘We can’t beat the Googles and the Facebooks, so let’s try to charge them.’ ”

The European lobbying group says that without the new fees, there will be no money to invest in network upgrades needed to deal with a surge in traffic. Regulators have required European telecommunications operators to open their networks to rivals, and the market for broadband is fiercely competitive, with rock-bottom prices.

In the United States, by contrast, most telecommunications companies have been permitted to maintain local monopolies — or duopolies, with cable companies — in broadband, keeping prices higher. And American regulators have ordered broadband providers to give equal priority to all Internet traffic. Such “network neutrality” is incompatible with charging content providers for moving their bits of data.

Analysts say this may explain why American telecommunications companies have not joined the European call for a new business model. “Models that try to force payment terms between nations and telecom operators run a huge risk of cutting off traffic,” Mr. Kramer said in an interview. “Liberalized markets are the only way to expand the success of the Internet.”

People who have been briefed on the conference submissions say that not a single European government delegation has endorsed the telecommunications operators’ proposal, and the European Parliament has passed a resolution denouncing it. Only governments, not private groups or companies, can put items on the meeting agenda.

While many documents prepared for the conference remain secret, several people who have seen submissions say there is broad support for Internet connection fees in French-speaking Africa and among Arab nations — countries in which many telecommunications companies are still owned or heavily regulated by governments.

Much of the attention before the 12-day conference has focused on a proposal from Russia that would effectively remove control of the Internet’s infrastructure from a collection of decentralized and apolitical organizations, mostly based in the United States. “Member states,” Russia proposed, “shall have equal rights to manage the Internet, including in regard to the allotment, assignment and reclamation of Internet numbering, naming, addressing and identification resources.”

Those functions are performed by the Internet Corporation for Assigned Names and Numbers, a private organization with an international board that operates under contract with the United States government.

The Russian proposal was widely interpreted as a call to legitimize domestic censorship of the Internet. Yet analysts note that governments inclined to filter the Web, like China and Iran, have not waited for consensus in an international meeting to do so.

Global Update: Investing in Eyeglasses for Poor Would Boost International Economy

Eliminating the worldwide shortage of eyeglasses could cost up to $28 billion, but would add more than $200 billion to the global economy, according to a study published last month in the Bulletin of the World Health Organization.

The $28 billion would cover the cost of training 65,000 optometrists and equipping clinics where they could prescribe eyeglasses, which can now be mass-produced for as little as $2 a pair. The study was done by scientists from Australia and the Johns Hopkins Bloomberg School of Public Health.

The authors assumed that 703 million people worldwide have uncorrected nearsightedness or farsightedness severe enough to impair their work, and that 80 percent of them could be helped with off-the-rack glasses, which would need to be replaced every five years.

The biggest productivity savings from better vision would not be in very poor regions like Africa but in moderately poor countries where more people have factory jobs or trades like driving or running a sewing machine.

Without the equivalent of reading glasses, “lots of skilled crafts become very difficult after age 40 or 45,” said Kevin Frick, a Johns Hopkins health policy economist and study co-author. “You don’t want to be swinging a hammer if you can’t see the nail.”

If millions of schoolchildren who need glasses got them, the return on investment could be even greater, he said, but that would be in the future and was not calculated in this study.

A Struggling CNN Casts Its Eyes on Jeffrey Zucker

In the days to come, when Time Warner appoints a new leader of CNN Worldwide for the first time in a decade, that person will face an identity crisis unlike any other in corporate America.

Though CNN over all is on track to have its most profitable year ever, its flagship channel in the United States is seemingly rudderless, run by layers of producers and executives — many with competing visions. Its low prime-time ratings are the stuff of punch lines and a journalism school case study in the damage wrought by the digital age.

Then again, CNN also has tremendous potential, an enviably popular Web site and countless people rooting for it to succeed.

Throughout a four-month search for the person to succeed Jim Walton, the departing president, attention has centered on Jeffrey Zucker, the former chief executive of NBCUniversal, who was replaced when Comcast took over the company last year. Mr. Zucker produces Katie Couric’s syndicated daytime talk show.

Several news executives close to Mr. Zucker said this week that they believed he had been chosen to run CNN, and they expected the appointment to be announced soon. People close to the Time Warner chief executive, Jeffrey L. Bewkes, also identified Mr. Zucker. A Time Warner spokesman declined to comment.

In considering candidates to run one of the world’s best-known, but beleaguered, news organizations, Mr. Bewkes and his deputy Phil Kent have also been considering their own legacies. They are cautious about not undermining CNN’s journalistic heart and soul, even as they strive to resuscitate the channel’s prime-time lineup, according to people who have met with them about the search. That means the channel’s programming will remain nonpartisan in nature.

“They want someone who has programming and management and cable expertise; someone who can be credible to the staff and to the business community,” one person said. “They know that this is a pretty tall order.”

Mr. Zucker could check off all those boxes. As a young NBC News producer, he helped start what became a 16-year winning streak for the “Today” show. He had mixed results as he moved up the rungs of NBC, but he can point to cable programming successes even as the NBC broadcast network struggled. He did not respond to requests for comment, and people with knowledge of the search insisted on anonymity to preserve friendships and business relationships.

But many others in and around CNN spoke on the record about the challenges ahead. Getting the top-heavy 4,000-person company — spread among New York, Washington, Atlanta and bureaus around the world — to row in the same direction will be one of the toughest tasks, many said.

CNN’s many channels and sites net roughly $600 million in annual profits, through advertising revenue and subscriber fees. But the channel is leaving ad dollars on the table, as one executive put it, because its prime-time ratings are lagging, and it is putting future fee increases at risk by appearing irrelevant in the eyes of some cable subscribers.

One problem dates back to CNN’s creation in 1980: when there is a lack of news, there is a lack of viewers. Kiran Chetry, a CNN morning anchor from 2007 to 2011, said her time there was like being on a news treadmill: “We were running, sweating, doing the work, but never getting anywhere ratings-wise,” she said. This stemmed, she said, from uncertainty about “what we were, who our audience was and how we best served them.”

As Fox News and, later, MSNBC put on confrontational political programs with partisan points of view, CNN sold itself as proudly nonpartisan, but it fell from first to second to third place in the cable news wars along the way. This should have been an “up” year for the channel, thanks to the presidential election; but through mid-November the channel had drawn 412,000 viewers at any given time, down 16 percent from the previous 12 months.

Egypt’s President Said to Limit Scope of Judicial Decree

Tara Todras-Whitehill for The New York Times

Egyptians stand near a burned out school, before the funeral of Mohammed Gaber Salah, an activist who died Sunday from injuries sustained during protests.

CAIRO — With public pressure mounting, President Mohamed Morsi appeared to pull back Monday from his attempt to assert an authority beyond the reach of any court. His allies in the Muslim Brotherhood canceled plans for a large demonstration in his support, signaling a chance to calm an escalating battle that has paralyzed a divided nation.

After Mr. Morsi met for hours with the judges of Egypt’s Supreme Judicial Council, his spokesman read an “explanation” on Egyptian television that appeared to backtrack from a presidential decree that had placed Mr. Morsi’s official edicts above judicial scrutiny — even while saying the president had not actually changed a word of the statement.

Though details of the talks remained hazy, and it was not at all clear whether the opposition or even the court would accept his position, Mr. Morsi’s gesture was another demonstration that Egyptians would no longer allow their rulers to operate above the law. But there appeared little chance that Mr. Morsi’s gesture alone would be enough to quell the crisis set off by his perceived power grab.

How far that gesture might go toward alleviating the political crisis, however, remained uncertain. Protesters remained camped in Tahrir Square, and the opposition was moving ahead with plans for a major demonstration on Tuesday.

In a televised statement, the presidential spokesman, Yasser Ali, said for the first time that Mr. Morsi had sought only to assert pre-existing powers already approved by the courts under previous precedents, not to give himself carte blanche from judicial oversight.

He said that the president meant all along to follow an established Egyptian legal doctrine suspending judicial scrutiny of presidential “acts of sovereignty” that work “to protect the main institutions of the state.” Mr. Morsi had maintained from the moment of his decree that his purpose was to empower himself to protect the constitutional assembly from threats that Mubarak-appointed judges might dissolve the constituent assembly, which is led by his fellow Islamists of the Muslim Brotherhood’s Freedom and Justice Party. The courts have already dissolved the Islamist-led Parliament and an earlier constituent assembly.

But the text of the original decree has exempted all presidential edicts from judicial review until the ratification of a constitution, not just those edicts justified as “acts of sovereignty.”

Legal experts said that the spokesman’s “explanations” of the president’s intentions, if put into effect, would amount to a revision of the decree he had issued last Thursday. But lawyers said that the verbal statements alone carried little legal weight.

How the courts would apply the doctrine remained hard to predict. And Mr. Morsi’s political opposition indicated it was holding out for far greater concessions, including the breakup of the Islamist-led constituent assembly.

Speaking at a news conference while Mr. Morsi was meeting with the judges, the opposition activist and intellectual Abdel Haleem Qandeil called for “a long-term battle,” declaring that withdraw of Mr. Morsi’s new powers was only the first step toward the opposition’s goal of “the withdrawal of the legitimacy of Morsi’s presence in the presidential palace.” Completely withdrawing the edict would be “a minimum,” he said.

Most in the opposition focused on the spokesman’s declaration that the president had not revised the text of his decree. Khaled Ali, a human rights lawyer and former presidential candidate, pointed to the growing crowd of protesters camped out in Tahrir Square for a fourth night. “Reason here means that the one who did the action has to take it back,” Mr. Ali said.

Moataz Abdel Fattah, a political scientist at Cairo University, said Mr. Morsi appeared to be trying to save face with a strategic retreat. “He is trying to simply say, ‘I am not a new pharaoh, I am just trying to stabilize the institutions that we already have,’ ” he said. “But for the liberals, this is now their moment, and for sure they are not going to waste it, because he has given them an excellent opportunity to score.”

Pogue’s Posts Blog: You Can Stop Spreading That Facebook Notice Now

For the last couple of days, my Facebook timeline, and probably yours, has been filled with repetitions of a peculiar piece of boilerplate text, from all kinds of friends. It goes something like this:

In response to the new Facebook guidelines, I hereby declare that my copyright is attached to all of my personal details, illustrations, comics, paintings, crafts, professional photos and videos, etc. (as a result of the Berner Convention).

For commercial use of the above my written consent is needed at all times!

Facebook is now an open capital entity. All members are recommended to publish a notice like this, or if you prefer, you may copy and paste this version.

Guess what? You’ve been hoaxed.

First, no declaration by you, in a Facebook posting, would make any difference to the legal status of your posts. You’re already protected by copyright law.

Second, there are no “new Facebook guidelines.” Facebook’s policy is this: “You retain the copyright to your content. When you upload your content, you grant us a license to use and display that content.”

Third, there’s no such thing as the Berner Convention. There’s a Berne Convention, which covers literary works.

Fourth, the fact that Facebook is now a publicly traded company has absolutely nothing to do with its copyright or privacy policies. They’re entirely unrelated.

Finally, Facebook itself has issued the following statement: “There is a rumor circulating that Facebook is making a change related to ownership of users’ information or the content they post to the site. This is false. Anyone who uses Facebook owns and controls the content and information they post, as stated in our terms. They control how that content and information is shared. That is our policy, and it always has been.”

Snopes, the anti-misinformation site, has already debunked this hoax. So you can stop pasting that meaningless “I hereby declare” status update. Let’s get back to hearing what you had for lunch.

Panel Lukewarm on Hepatitis C Screening for Baby Boomers

An influential advisory committee has given only lukewarm support to a government recommendation that all baby boomers be tested for hepatitis C.

In a draft opinion Monday, the United States Preventive Services Task Force said that clinicians may “consider offering” hepatitis C screening to adults born between 1945 and 1965.

That falls short of the recommendation made in August by the Centers for Disease Control and Prevention that all adults in that age group should get a one-time test to see if they are infected.

The task force is made up of outside experts appointed by the government, and its recommendations can in some cases carry more weight than those of the C.D.C. Had hepatitis C screening for baby boomers received a stronger recommendation from the task force, health plans would have been required to pay for it under the 2010 Affordable Care Act, with no charge to the patient.

Some advocates of wider screening said they feared the new opinion would be used by insurers to deny reimbursement for testing and would slow efforts to ferret out hidden cases of hepatitis C at a time when more effective and tolerable treatments are being developed.

The recommendation “could derail the hard work that the C.D.C. has put in in proving the case that it’s smart for baby boomers to get a one-time hepatitis C test,” said Martha B. Saly, director of the National Viral Hepatitis Roundtable, a coalition of more than 200 groups dedicated to eradicating hepatitis. Some drug companies, which would benefit from wider screening, are associate members of the round table.

Dr. Kirsten Bibbins-Domingo, of the University of California, San Francisco, and a member of the task force, said differences in the recommendations were merely a matter of degree. “I would say our findings are compatible,” she said.

The C.D.C. declined to comment, saying the opinion was still a draft.

About 3 million Americans are infected with hepatitis C, but 45 percent to 85 percent of them do not know it, according to the C.D.C. The virus can cause scarring of the liver and liver cancer, though typically not until decades after the initial infection, and not in everyone. About 15,000 people a year die from hepatitis C.

The C.D.C. used to recommend screening only for people most likely to be infected: intravenous drug users or people who got blood transfusions before 1992 when testing of donated blood for the virus began.

But a lot of cases were missed because people did not remember risky behaviors from decades ago or did not tell their doctors.

So in August the C.D.C. recommended that all baby boomers be tested. Although only about 3 percent of this age group is infected, they account for about three quarters of all cases. Screening them would detect more than 800,000 infections, which could then potentially be treated, averting many cases of liver disease and about 120,000 deaths.

But the task force said there were no clinical trials or studies directly proving that screening asymptomatic adults would reduce liver disease or deaths.

It noted that the C.D.C. recommendation was based partly on computer models that might have overestimated how many people with hepatitis C would develop liver cirrhosis or die, and therefore overstated the number of cases or deaths that could be prevented.

The task force concluded that there would be at least a small benefit from screening baby boomers and gave the recommendation a grade of C, meaning “for most individuals without signs or symptoms there is likely to be only a small benefit from this service.”

The task force provoked controversy in the past with recommendations against screening for prostate cancer and against routine mammograms for women under 50.

In 2004, the task force recommended against hepatitis C screening of adults not considered at high risk.

The draft, posted on the task force Web site, will be open for comment until Dec. 24. The evidence behind the recommendation is being published in The Annals of Internal Medicine.
