Fair Game: New York Fed Agreed to Testify for Bank of America

A.I.G., which is suing Bank of America to recover losses it suffered on those securities, has calculated the value of the fraud claims at $7 billion.

Late on Thursday, a copy of the actual agreement came to light. It was filed by Bank of America in a California court that is hearing the matter of who owns those fraud claims — A.I.G. or the New York Fed. The agreement was also filed by the New York Fed in a related lawsuit in the Southern District of New York, where the New York Fed asked that the court keep the agreement under seal.

A reading of the document makes it clear why.

The agreement spells out the terms of a deal in which the New York Fed received $43 million from Bank of America’s Countrywide unit. The money changed hands to settle a narrow dispute involving cash flows on several mortgage securities held by an investment vehicle, known as Maiden Lane II. That vehicle was created by the New York Fed as part of the rescue of A.I.G., which had held the Countrywide securities. The previously confidential agreement released Bank of America from all litigation claims on the securities held by Maiden Lane II.

But in exchange for that $43 million, the New York Fed did something else for Bank of America. It agreed to testify on behalf of the bank in its legal battle against A.I.G. over fraud claims.

In that matter, Bank of America has argued that A.I.G. has no right to sue it for fraud because A.I.G. sold the securities to Maiden Lane II and so transferred the litigation rights to the New York Fed. A.I.G., however, maintains that the Maiden Lane agreement never specified the transfer of the right to sue for fraud and that an explicit transfer is required by New York law, which governs the agreement. The New York Fed provided Bank of America with two affidavits supporting the bank’s view of who owned the mortgage securities’ fraud claims.

Two weeks ago, it was unclear why the New York Fed gave Bank of America the affidavits. But now, its promise to testify “as needed,” shown in the formerly confidential settlement, addresses that oddity. It was a contractual obligation.

Interestingly, the New York Fed did not tell the California court that its affidavits came about because of its deal with Bank of America. The affidavits came from James M. Mahoney, a vice president at the New York Fed, and Stephanie A. Heller, its deputy general counsel.

But those affidavits differ from the position taken earlier by Thomas C. Baxter Jr., the New York Fed’s general counsel. In a letter to A.I.G. in October 2011, Mr. Baxter said that he and his colleagues “agree that A.I.G. has the right to seek damages” under securities laws for the instruments it sold to Maiden Lane II.

Michael Carlinsky, A.I.G.’s lawyer at Quinn Emanuel Urquhart & Sullivan, said on Friday that he found it “disturbing” that the New York Fed made a contract to “assist Bank of America in its defense of A.I.G.’s lawsuit.”

Also on Friday, I asked the New York Fed why it had included this promise of legal support for Bank of America in the settlement agreement. Jack Gutt, a spokesman, said in a statement that the New York Fed had intended to hold the litigation rights and that the declarations were true.

“The New York Fed did not agree to provide the declarations to benefit B. of A., but rather because doing so helped the New York Fed obtain the best possible settlement” for Maiden Lane II, Mr. Gutt said. “In agreeing to this provision as part of what the New York Fed believed was a favorable settlement agreement, the New York Fed was concerned exclusively with advancing the taxpayer interest.”

I also asked a Bank of America spokesman whether the bank had paid more in the settlement because of the New York Fed’s promise to testify. He declined to answer that question, saying, “Countrywide provided fair value for a complete release of claims by the Federal Reserve Bank of New York, and the Fed agreed to provide testimony standing behind what it had formally represented to Countrywide regarding the assignment of claims from A.I.G.”

England Develops a Voracious Appetite for a New Diet

LONDON — Visitors to England right now, be warned. The big topic on people’s minds — from cabdrivers to corporate executives — is not Kate Middleton’s increasingly visible baby bump (though the craze does involve the size of one’s waistline), but rather a best-selling diet book that has sent the British into a fasting frenzy.

“The Fast Diet,” published in mid-January in Britain, could do the same in the United States if Americans eat it up. The United States edition arrived last week.

The book has held the No. 1 slot on Amazon’s British site nearly every day since its publication in January, according to Rebecca Nicolson, a founder of Short Books, the independent publishing company behind the sensation. “It is selling,” she said, “like hot cakes,” which coincidentally are something one can actually eat on this revolutionary diet.

With an alluring cover line that reads, “Lose Weight, Stay Healthy, Live Longer,” the premise of this latest weight-loss regimen — or “slimming” as the British call “dieting” — is intermittent fasting, or what has become known here as the 5:2 diet: five days of eating and drinking whatever you want, dispersed with two days of fasting.

A typical fasting day consists of two meals of roughly 250 to 300 calories each, depending on the person’s sex (500 calories for women, 600 for men). Think two eggs and a slice of ham for breakfast, and a plate of steamed fish and vegetables for dinner.

It is not much sustenance, but the secret to weight loss, according to the book, is that even after just a few hours of fasting, the body begins to turn off the fat-storing mechanisms and turn on the fat-burning systems.

“I’ve always been into self-experimentation,” said Dr. Michael Mosley, one of the book’s two authors and a well-known medical journalist on the BBC who is often called the Sanjay Gupta of Britain.

He researched the science of the diet and its health benefits by putting himself through intermittent fasting and filming it for a BBC documentary last August called “Eat, Fast and Live Longer.” (The broadcast gained high ratings, three million viewers, despite running during the London Olympics. PBS plans to air it in April.)

“This started because I was not feeling well last year,” Dr. Mosley said recently over a cup of tea and half a cookie (it was not one of his fasting days). “It turns out I was suffering from high blood sugar, high cholesterol and had a kind of visceral fat inside my gut.”

Though hardly obese at the time, at 5 feet 11 inches and 187 pounds, Dr. Mosley, 55, had a body mass index and body fat percentage that were a few points higher than the recommended amount for men. “Given that my father had died at age 73 of complications from diabetes, and I was now looking prediabetic, I knew something had to change,” he added.

The result was a documentary, almost the opposite of “Super Size Me,” in which Dr. Mosley not only fasted, but also interviewed scientific researchers, mostly in the United States, about the positive results of various forms of intermittent fasting, tested primarily on rats but in some cases human volunteers. The prominent benefits, he discovered, were weight loss, a lower risk of cancer and heart disease, and increased energy.

“The body goes into a repair-and-recover mode when it no longer has the work of storing the food being consumed,” he said.

Though Dr. Mosley quickly gave up on the most extreme forms of fasting (he ate little more than one cup of low-calorie soup every 24 hours for four consecutive days in his first trial), he finally settled on the 5:2 ratio as a more sustainable, less painful option that could realistically be followed without annihilating his social life or work.

“Our earliest antecedents,” Dr. Mosley argued, “lived a feast-or-famine existence, gorging themselves after a big hunt and then not eating until they scored the next one.” Similarly, he explained, temporary fasting is a ritual of religions like Islam and Judaism — as demonstrated by Ramadan and Yom Kippur. “We shouldn’t have a fear of hunger if it is just temporary,” he said.

What Dr. Mosley found most astounding, however, were his personal results. Not only did he lose 20 pounds (he currently weighs 168 pounds) in nine weeks, but his glucose and cholesterol levels went down, as did his body fat. “What’s more, I have a whole new level of energy,” he said.

The documentary became an instant hit, which in turn led Mimi Spencer, a food and fashion writer, to propose that they collaborate on a book. “I could see this was not a faddish diet but one that was sustainable with long-term health results, beyond the obvious weight-loss benefit,” said Ms. Spencer, 45, who has lost 20 pounds on the diet within four months and lowered her B.M.I. by 2 points.

The result is a 200-page paperback: the first half written by Dr. Mosley outlining the scientific findings of intermittent fasting; the second by Ms. Spencer, with encouraging text on how to get through the first days of fasting, from keeping busy so you don’t hear your rumbling belly, to waiting 15 minutes for your meal or snack.

She also provides fasting recipes with tantalizing photos like feta niçoise salad and Mexican pizza, and a calorie counter at the back. (Who knew a quarter of a cup of balsamic vinegar added up to a whopping 209 calories?)

In London, the diet has taken off with the help of well-known British celebrity chefs and food writers like Hugh Fearnley-Whittingstall, who raved about it in The Guardian after his sixth day of fasting, having already lost eight pounds. (“I feel lean and sharper,” he wrote, “and find the whole thing rather exhilarating.”)

The diet is also particularly popular among men, according to Dr. Mosley, who has heard from many of his converts via e-mail and Twitter, where he has around 24,000 followers. “They find it easy to work into their schedules because dieting for a day here and there doesn’t feel torturous,” he said, adding that couples also particularly like doing it together.

But not everyone is singing the diet’s praises. The National Health System, Britain’s publicly funded medical establishment, put out a statement on its Web site shortly after the book came out: “Despite its increasing popularity, there is a great deal of uncertainty about I.F. (intermittent fasting) with significant gaps in the evidence.”

The health agency also listed some side effects, including bad breath, anxiety, dehydration and irritability. Yet people in London do not seem too concerned. A slew of fasting diet books have come out in recent weeks, notably the “The 5:2 Diet Book” and “The Feast and Fast Diet.”

There is also a crop of new cookbooks featuring fasting-friendly recipes. Let’s just say, the British are hungry for them.

Jennifer Sultan Pleads Guilty to Selling Prescription Drugs

At the height of dot-com mania 13 years ago, Jennifer Sultan and a few colleagues sold their small technology company for $70 million in stock and cash. She and her boyfriend rented a large house in the Hamptons for the summer and bought a spacious loft near Union Square.

John Marshall Mantel for The New York Times

Jennifer Sultan faced 15 years to life on the top charge against her, and a potential for more prison time on other counts.

In the years since, that temporary flush of wealth evaporated and Ms. Sultan, 38, developed an addiction to prescription painkillers.

On Friday, she sat handcuffed in a courtroom at State Supreme Court in Manhattan. In exchange for a promise of a four-year prison sentence, she pleaded guilty to selling prescription painkillers and conspiring to sell a firearm.

She was arrested last July and accused of being part of a ring that sold prescription drugs and guns. Four others arrested with Ms. Sultan had already pleaded guilty. One, Nicholas Mina, a former New York City police officer, agreed to serve more than 15 years in prison as part of a plea bargain under which he admitted stealing guns from his colleagues’ precinct house lockers and selling them. Mr. Mina was also addicted to prescription painkillers.

Though Ms. Sultan’s lawyer said she had hoped for less than four years, she faced 15 years to life in prison on the top count against her and the potential for more prison time on other charges. She said little in court but smiled broadly several times as she spoke quietly with her lawyer, Frank Rothman.

“She was happy to be done with it, but she was not happy with the sentence,” Mr. Rothman said afterward.

Ms. Sultan grew up in West Long Branch, N.J., five miles north of Asbury Park, and graduated from New York University in 1996. She and her boyfriend at the time, Adam Cohen, worked at a company, Live Online, that was an early pioneer in live streaming events on the Internet.

After the sale of Live Online, efforts by Ms. Sultan and Mr. Cohen to start other technology companies failed. Ms. Sultan explored other interests, including acupuncture and holistic health.

Early last year, a city narcotics investigator discovered an advertisement Ms. Sultan had placed on Craigslist offering prescription painkillers for sale. She and Mr. Cohen were still living in the penthouse loft near Union Square that they bought after the sale of Live Online.

Five times from February through June, she sold pills to an undercover officer, according to her indictment. One sale took place at the Starbucks on Union Square. In another, she sold 183 oxycodone tablets to the officer for $4,400 at a Starbucks in the Flatiron district near the school where she was studying acupuncture.

A separate investigation into the ring that sold stolen guns and pain medication picked up Ms. Sultan sending a text message to the man accused of being the ringleader, Ivan Chavez, saying she wanted to sell him a .357 Magnum handgun for $850, according to a separate indictment obtained by the Manhattan district attorney.

Mr. Chavez was sentenced to 20 years in prison.

Ms. Sultan and Mr. Cohen, who was not accused of participating in the drug and guns ring, filed for bankruptcy in 2010. Last August, the bankruptcy judge ordered them to vacate the loft to allow a bankruptcy trustee to sell it. The 5,600-square-foot loft is still listed for sale at just under $6 million.

She has been incarcerated since her arrest in July because she was unable to raise $85,000 for bail. With credit for good behavior and time served since her arrest, Ms. Sultan could be released from prison in about two years.

Seized Arms Off Yemen Raise Alarm Over Iran

An Iranian dhow seized off the Yemeni coast was carrying sophisticated Chinese antiaircraft missiles, a development that could signal an escalation of Iran’s support to its Middle Eastern proxies, alarming other countries in the region and renewing a diplomatic challenge to the United States.

Among the items aboard the dhow, according to a review of factory markings on weapons and their packing crates, were 10 Chinese heat-seeking antiaircraft missiles, most of them manufactured in 2005.

The missiles were labeled QW-1M and bore stencils suggesting that they had been assembled at a factory represented by the state-owned China National Precision Machinery Import and Export Corporation, sanctioned by the United States for transfers of missile technology to Pakistan and Iran.

The Chinese missiles were part of a larger shipment interdicted by American and Yemeni forces in January, which American and Yemeni officials say was intended for the Houthi rebels in northwestern Yemen. But the presence of the missiles in the seized contraband complicates an already politically delicate case.

The shipment, which officials portray as an attempt to introduce sophisticated new antiaircraft systems into the Arabian Peninsula, has raised concerns in Saudi Arabia, Oman and Yemen, as the weapons would have posed escalated risks to civilian and military aircraft alike.

And it has presented the Obama administration with a fresh example of Iran’s apparent transfer of modern missiles from China to insurgents in the larger regional contest between Sunni-led and Shiite-led states, in which the American military has often been entwined.

The United States has previously accused Iran, a Shiite-led theocracy, of sending weapons to the Houthis, who follow an offshoot of Shiite Islam. Saudi Arabia, an American ally, is considered the leading Sunni power in the region. Both sides have aided and equipped groups or governments they deem aligned with their interests, helping to fuel violence in Yemen, Iraq, Syria, Lebanon, the Palestinian territories, Sudan and elsewhere.

Iran has rejected the allegations as “baseless and absurd.” Neither the Iranian government nor the Chinese firm that markets QW missiles answered written requests for comment.

The government of Yemen has asked the United Nations to investigate the shipment and report the findings to the Security Council. Yemeni news media reported that United Nations experts were in Yemen last week.

The analysis of the weapons’ markings and origins was based on photographs taken when Yemeni officials briefly displayed the weapons to journalists.

Concerns over sophisticated Chinese missiles reaching Iran’s proxies have considerable regional history. They are part of both the larger worries over antiaircraft weapons set loose by conflicts across the Middle East in the past decade and the lingering frustration in Washington over China’s military aid to Iran.

In 2008, late in the Bush administration, the United States complained to China about two similar antiaircraft missiles that were recovered from Shiite militants in Iraq, according a diplomatic cable made public by WikiLeaks.

“We have demarched China repeatedly on its conventional arms transfers to Iran, urging Beijing to stop,” the cable noted.

The cable said the QW-1 missiles recovered in Iraq had been manufactured in China in 2003.

Like the American-made Stinger, China’s QW series is part of a class of weapons known as man-portable air-defense systems, or manpads. The cable instructed American diplomats to warn China of the “unacceptably high risk that any military equipment sold to Iran, especially weapons like manpads, that are highly sought-after by terrorists, will be diverted to nonstate actors who threaten U.S. and coalition forces in Iraq and Afghanistan as well as civilians across the region.”

The latest discovery of Chinese manpads came after the United States Navy detected the dhow, the Jeehan 1, as it took on cargo in an Iranian military-controlled port. The vessel then embarked on a high-seas smuggling run, according to accounts by Yemeni and American officials.

The vessel tied off on a pier in the harbor on Lesser Tunb Island, a tiny spit of land just west of the Strait of Hormuz that is claimed by both Iran and the United Arab Emirates, officials familiar with its voyage said. The island is occupied by Iran’s Revolutionary Guards.

After passing eastward through the strait and heading south along the Arabian Peninsula, the dhow was stopped on Jan. 23 by the American destroyer Farragut and a Yemeni boarding team off the coast of Al Ghaydah.

The dhow’s Iranian crew initially insisted the vessel was Panamanian-flagged and carried only fuel, an American official said. The military cargo, which included many ammunition crates that had been painted over with white or black paint, was found in hidden compartments, American officials said.

That cargo also included 316,000 cartridges for Kalashnikov rifles, nearly 63,000 cartridges for PK machine guns or the Dragunov series of sniper rifles, more than 12,000 cartridges for 12.7-millimeter DShK machine guns and 95 RPG-7 launchers.

The rifle cartridges were packaged in crates strongly resembling packaging used by Iran’s Defense Industries Organization, another firm under American sanction, according to James Bevan, director of Conflict Armament Research, a private arms-tracking firm that has documented the spread of Iranian ammunition in East and West Africa.

The vessel also carried 10 SA-7 shoulder-fired antiaircraft missiles with two gripstocks for firing them, nearly 17,000 sticks of Iranian-made C-4 plastic explosives, 48 Russian PN-14K night vision goggles, and 10 LH80A laser range finders made, according to their placards, by the state-run Iran Electronics Industries, also under American sanction.

The original provenance of the SA-7s was not clear, though the crates they were in had stenciling in Bulgarian.

The captain and crew of the Jeehan 1 remain in Yemeni detention, and the dhow has been impounded under Yemeni custody, a Yememi official said.

An American official called the shipment “deeply disturbing” and said it “clearly appeared to violate” Security Council resolutions prohibiting Iran from exporting arms.

Two independent arms-trafficking researchers who have reviewed photographs and written a summary of the markings on the missiles and crates said the weapons appeared to be of Chinese origin.

Matthew Schroeder, an analyst for the Federation of American Scientists in Washington and the Small Arms Survey in Geneva, said that this was the first time to his knowledge that the QW-1M had left state control.

“If so, and these missiles were indeed bound for insurgents, this shipment is extremely worrisome, both from a regional security and a global counterterrorism perspective,” he said.

Unlike many older shoulder-fired antiaircraft missiles seen in insurgent hands around the world, the QW-1M is believed by analysts to have a seeker head more resistant to countermeasures intended to deceive it.

Detroit Car Sales Climb Again

DETROIT – Sales of new vehicles in the United States rose modestly in February, as consumers continued to buy more fuel-efficient cars and as businesses replaced aging pickup trucks with newer models.

Auto executives said overall industry sales for the month would improve about 2 percent over the strong results reported in the same period a year ago.

The seasonally adjusted annual sales rate – a closely watched indicator for the industry – is expected to total about 15.5 million vehicles for February.

That seasonal rate bodes well for the industry going forward, as automakers ratchet up production to meet demand for their new products.

The Detroit auto companies all posted positive results during the month.

General Motors, the largest American automaker, said it sold 224,000 vehicles in February, a 7 percent increase from the same month in 2012.

All of G.M.'s domestic brands – Chevrolet, Cadillac, GMC and Buick – had higher year-over-year sales. Cadillac led the way with a 20 percent gain, primarily because of healthy sales of the new ATS compact sedan.

G.M. also reported increases in sales of its newest small cars, like the Buick Verano and the Chevrolet Spark. But its most prominent gains were in pickup trucks.

The company said that sales of the Chevrolet Silverado pickup rose 29 percent, and the GMC Sierra increased 25 percent. Executives attributed the performance to a surge in housing starts and the need for construction companies to replace older pickups.

“A significant tailwind for our industry is new home construction, which is creating jobs and fueling the demand for pickups,” said Kurt McNeil, G.M.'s vice president of United States sales operations.

The Ford Motor Company, the second-biggest Detroit auto company, said it sold 195,000 vehicles during the month, a 9 percent gain from a year ago.

Ford said that many of its gains came from sales of sport utilities such as the Escape and Explorer. The company’s redesigned midsize sedan, the Fusion, also had a good month, with a 28 percent improvement over last year.

Like G.M., Ford also benefitted from the surging demand for pickups. Ford said that it sold 54,000 F-series trucks during the month, a 15 percent increase from February of 2012.

Chrysler, the smallest of the Detroit automakers, saw its growth rate slow somewhat after several months of reporting double-digit increases.

The company said that it sold 139,000 vehicles in February, a 4 percent improvement over a year earlier. That is a smaller increase than Chrysler has reported in previous months.

“In spite of a cautious ramp-up of some of our most popular products, which limited inventory last month, we still managed to record our strongest February in five years,” said Reid Bigland, head of United States sales for Chrysler.

Chrysler’s best performers during the month were passenger cars such as the new Dodge Dart. Sales of its Ram pickup increased 3 percent, while sales of its Jeep SUVs dropped 16 percent.

The big Japanese automakers were to report results later Friday. Analysts expected Toyota and Honda to continue their steady comeback from inventory disruptions because of the earthquake and tsunami in Japan two years ago.

Volkswagen, the German automaker that is rapidly expanding its American operations, said it sold 31,000 vehicles in February, a 3 percent increase from a year earlier.

Think Like a Doctor: The Man Who Wobbled

The Challenge: Can you solve the medical mystery of a man who suddenly becomes too dizzy to walk?

Every month, the Diagnosis column of The New York Times Magazine asks Well readers to try their hand at solving a medical mystery. Below you will find the story of a 56-year-old factory worker with dizziness and panic attacks. I have provided records from his two hospital visits that will give you all the information available to the doctor who finally made the diagnosis.

The first reader to offer the correct diagnosis gets a signed copy of my book, “Every Patient Tells a Story,” and the satisfaction of solving a case that stumped a roomful of specialists.

The Patient’s Story:

The middle-aged man clicked his way through the multiple reruns of late-late-night television. He should have been in bed hours ago, but lately he hadn’t been able to get to sleep. Suddenly his legs took on a life of their own. Stretched out halfway to the center of the room, they began to shake and twitch and jump around. The man watched helplessly as his legs disobeyed his mental orders to stop moving. He had no control over them. He felt nauseous, sweaty and out of breath, as if he had been running some kind of race. He called out to his wife. She hurried out of bed, took one look at him and called 911.

The Patient’s History:

By the time the man arrived at Huntsville Hospital, in Alabama, the twitching in his legs had subsided and his breathing had returned to normal. Still, he had been discharged from that same hospital for similar symptoms just two weeks earlier. They hadn’t figured out what was going on then, so they weren’t going to send him home now.

The patient considered himself pretty healthy, but the past year or so had been tough. In 2011, at the age of 54, he had had a mild stroke. He had no medical problems that put him at risk for stroke — no high blood pressure, no high cholesterol, no diabetes. A work-up at that time showed that he had a hole in his heart that allowed a tiny clot from somewhere in his body to travel to the brain and cause the stroke. He was discharged on a couple of blood thinners to keep his blood from making more clots. He hadn’t really felt completely well, though, ever since. His balance seemed a little off, and he was subject to these weird panic attacks, in which his heart would pound and he would feel short of breath whenever he got too stressed. Mostly he could manage them by just walking away and focusing on his breathing. Still, he never felt as if he was the kind of guy to panic.

And he had always been quick on his feet. The first half of his career he had been in the steel business — building huge metal trusses and supports. He and his team put together 60-plus tons of steel structures every day. For the past decade he had been machining car parts. After his stroke, work seemed to get a lot harder.

The Dizziness:

A few weeks ago, he stood up and wham — suddenly the whole world went off-kilter. He felt as if he was constantly about to fall over in a world that no longer lay down flat. His first thought was that he was having another stroke. He went straight to his doctor’s office. The doctor wasn’t sure what was going on and sent him to that same emergency room at Huntsville Hospital. After three days of testing and being evaluated by lots of specialists, his doctors still were not sure what was going on. He hadn’t had a heart attack; he hadn’t had a stroke. There was no sign of infection. All the tests they could think of were normal.

The only abnormal finding was that when he stood up, his blood pressure dropped. Why this happened wasn’t clear, but the doctors in the hospital gave him compression stockings and a pill — both could help keep his blood pressure in the normal range. Then they sent him home. He was also started on an antidepressant to help with the panic attacks he continued to have from time to time.

You can read the report from that hospital admission below.

You can also read the consultation and discharge notes from that hospital visit here.

He had been home for nearly two weeks and still he felt no better. He tried to go back to work after a week or so at home, but after driving for less than five miles, he felt he had to turn around. He wasn’t sure what was wrong; he just knew he didn’t feel right. Then his legs started jumping around, and he ended up back in the hospital.

The Doctor’s Exam:

It was nearly dawn by the time Dr. Jeremy Thompson, the first-year resident on duty that night, saw the patient. Awake but tired, the patient told his story one more time. He had been at home, watching TV, when his legs started jumping on their own and he started feeling short of breath. His wife sat at the bedside. She looked just as worried and exhausted as he did. She told the resident that when he spoke that night at home, his speech was slurred. And when the ambulance came, he could barely walk. He has never missed this much work, she told the young doctor. It’s not like him. Can’t you figure out what’s wrong?

The resident had already reviewed the records from the patient’s previous hospital admissions. He asked a few more questions: the patient had never smoked and rarely drank; his father died at age 80; his mother was still alive and well. The patient exam was normal, as were the studies done in the E.R.

The first E.R. doctor thought that his symptoms were a result of anxiety, culminating in a full-blown panic attack. The resident thought that was probably right. In any case he would discuss the case with the attending in a couple of hours during rounds on the new patients. Till then, he told the worried couple, they should just try to get a little sleep.

An Important Clue:

Dr. Robert Centor was definitely a morning person. His cheerful enthusiasm about teaching and taking care of patients made him a favorite among residents. At 7:30 that morning, he stood outside the patient’s door as Dr. Thompson relayed the somewhat frustrating case of the middle-aged man with worsening dizziness and panic attacks. Then they went into the room to meet the patient. He was a big guy, tall and muscular with the first signs of middle-aged thickening around his middle. His complexion had the look of someone who spent a lot of time outdoors. Dr. Centor introduced himself and pulled up a chair as the rest of the team watched. He asked the patient what brought him to the hospital.

“Every time I get up, I get dizzy,” the man replied. Sure, he had had some balance problems ever since his stroke, he explained, but this felt different – somehow worse. He could hardly walk, he told the doctor. He just felt too unstable.

“Can you get up and show us how you walk?” Dr. Centor asked.

“Don’t let me fall,” the patient responded. He carefully swung his legs over the side of the bed. The resident and intern stood on either side as he slowly rose. He stood with his feet far apart. When asked to close his eyes as he stood there, he wobbled and nearly fell over. When he took a few steps, his heel and toes hit the ground at the same time, making a strange slapping sound.

Seeing that, Dr. Centor knew where the problem lay and ordered a few tests to confirm his diagnosis.

You can see the review report and notes for the patient’s second hospital visit below.

Think Like a Doctor: The Man Who Wobbled

The Challenge: Can you solve the medical mystery of a man who suddenly becomes too dizzy to walk?

Every month, the Diagnosis column of The New York Times Magazine asks Well readers to try their hand at solving a medical mystery. Below you will find the story of a 56-year-old factory worker with dizziness and panic attacks. I have provided records from his two hospital visits that will give you all the information available to the doctor who finally made the diagnosis.

The first reader to offer the correct diagnosis gets a signed copy of my book, “Every Patient Tells a Story,” and the satisfaction of solving a case that stumped a roomful of specialists.

The Patient’s Story:

The middle-aged man clicked his way through the multiple reruns of late-late-night television. He should have been in bed hours ago, but lately he hadn’t been able to get to sleep. Suddenly his legs took on a life of their own. Stretched out halfway to the center of the room, they began to shake and twitch and jump around. The man watched helplessly as his legs disobeyed his mental orders to stop moving. He had no control over them. He felt nauseous, sweaty and out of breath, as if he had been running some kind of race. He called out to his wife. She hurried out of bed, took one look at him and called 911.

The Patient’s History:

By the time the man arrived at Huntsville Hospital, in Alabama, the twitching in his legs had subsided and his breathing had returned to normal. Still, he had been discharged from that same hospital for similar symptoms just two weeks earlier. They hadn’t figured out what was going on then, so they weren’t going to send him home now.

The patient considered himself pretty healthy, but the past year or so had been tough. In 2011, at the age of 54, he had had a mild stroke. He had no medical problems that put him at risk for stroke — no high blood pressure, no high cholesterol, no diabetes. A work-up at that time showed that he had a hole in his heart that allowed a tiny clot from somewhere in his body to travel to the brain and cause the stroke. He was discharged on a couple of blood thinners to keep his blood from making more clots. He hadn’t really felt completely well, though, ever since. His balance seemed a little off, and he was subject to these weird panic attacks, in which his heart would pound and he would feel short of breath whenever he got too stressed. Mostly he could manage them by just walking away and focusing on his breathing. Still, he never felt as if he was the kind of guy to panic.

And he had always been quick on his feet. The first half of his career he had been in the steel business — building huge metal trusses and supports. He and his team put together 60-plus tons of steel structures every day. For the past decade he had been machining car parts. After his stroke, work seemed to get a lot harder.

The Dizziness:

A few weeks ago, he stood up and wham — suddenly the whole world went off-kilter. He felt as if he was constantly about to fall over in a world that no longer lay down flat. His first thought was that he was having another stroke. He went straight to his doctor’s office. The doctor wasn’t sure what was going on and sent him to that same emergency room at Huntsville Hospital. After three days of testing and being evaluated by lots of specialists, his doctors still were not sure what was going on. He hadn’t had a heart attack; he hadn’t had a stroke. There was no sign of infection. All the tests they could think of were normal.

Gadgetwise Blog: App Smart Extra: Starry Night

Stars, galaxies, meteors and satellites were the subject of App Smart this week as I tested out astronomy apps to help identify objects in the night sky. These apps typically use your phone or tablet’s sensors to display a view of what you’re pointing your device at in the sky in real time, helping you identify planets and constellations. Here are more apps like this to try out:

Star Walk — 5 Stars Astronomy Guide is a popular iOS app, costing $3. It has the same kind of dynamic star display as other apps in its class, and it’s easy to use. It’s also jam-packed with imagery and data on the 200,000 stars and planets in its database, and has a calendar so you can keep track of interesting celestial events. I particularly like the beautiful imagery it uses to show constellations and detail on the planets.

SkySafari 3 may be useful for more experienced star gazers. It has data on 120,000 stars and 220 star clusters, nebulae and galaxies, as well as detailed information pages written by professional astronomers. The basic version costs $3 on iOS, but there’s a Plus edition for $15 that has data on 2.5 million stars and can control some wired and wireless telescopes. The Pro edition is $40 and has many more stars and features but is aimed at the serious amateur astronomer.

Alternatively, and much more simply, there’s SkEye Astronomy, available as a free Android app. It has a businesslike feel, and is slightly sparing on user interface touches like icons. But it is powerful, and essentially works in much the same way as Star Walk or SkySafari does. There’s a $9 SkEye Pro version that has more stars in its database and can help you spot satellites too. But the free edition is fine for the casual astronomer. The app is not ideal you’re a complete beginner, however, as it lacks the kind of detailed background data on stars and so on that similar apps have.

The benefit to stargazing apps like these is that they also work during the day, or in a city that’s too light-polluted to let you see more than a handful of stars. This means you can turn them on at any time to learn more about astronomy.

Quick call: The Popular instant messaging app WhatsApp has been updated to a new version for Windows Phone 8. It has better support for Windows Live Tile displays and extras like a back-up system.

DealBook: For S.E.C., a Setback in Bid for More Time in Fraud Cases

The Supreme Court on Wednesday delivered a swift and decisive rejection of the Securities and Exchange Commission’s argument that it should operate under a more forgiving statute of limitations in pursuing penalties in fraud cases.

As a result of the decision, the agency will have to find a long-term solution to give itself more time to investigate cases.

In Gabelli v. Securities and Exchange Commission, Chief Justice John G. Roberts Jr. wrote in the unanimous decision rejecting the S.E.C.’s argument that a federal statute that limits the government’s authority to pursue civil penalties should commence when a fraud is discovered, not when it occurred.

The S.E.C. was hoping that the court would apply what is known as the “discovery rule.” In 2010, the Supreme Court endorsed this rule in a private securities fraud class-action suit, Merck & Co. v. Reynolds, stating “that something different was needed in the case of fraud, where a defendant’s deceptive conduct may prevent a plaintiff from even knowing that he or she has been defrauded.”

The discovery rule is an exception to the protection afforded by a statute of limitations, which puts an endpoint on potential legal liability for conduct. Unlike most cases, when fraud is involved, it may not be apparent to the victims that they were harmed because the primary goal of deceptive conduct is to keep it from being exposed.

In the Gabelli case, the S.E.C. filed fraud charges in 2008 against the mutual fund manager Marc Gabelli and a colleague, Bruce Alpert, saying they had violated the Investment Advisers Act of 1940 for permitting an investor to engage in market timing. Ten years ago, a major scandal erupted when it came to light that some advisers had permitted select investors to buy shares at favorable prices to take advantage of pricing disparities in the securities held by mutual funds.

In its complaint, the S.E.C. sought civil monetary penalties based on market timing that it claimed had taken place from 1999 to 2002, and resulted in the preferred investor purportedly reaping significant profits while ordinary investors suffered large losses. The defendants denied the charges and filed a motion to dismiss the case because it was not brought in time.

A federal statute, 28 U.S.C. § 2462, provides that “an action, suit or proceeding for the enforcement of any civil fine, penalty, or forfeiture, pecuniary or otherwise, shall not be entertained unless commenced within five years from the date when the claim first accrued.” The provision dates to 1839, and applies to any government agency.

A decision by the United States Court of Appeals for the Second Circuit in Manhattan allowed the case to proceed by applying the discovery rule to a governmental action. Coincidentally, that decision was written by Judge Jed S. Rakoff, who despite being an occasional thorn in the S.E.C.’s side, accepted the agency’s argument to avoid a strict application of the five-year statute of limitations.

The Supreme Court, however, saw things differently. This week, it issued its opinion less than two months after it heard oral argument in the case in January, a clear sign the justices found no merit in the S.E.C.’s contention that the agency should be treated the same as private plaintiffs in trying to get around the statute of limitations.

According to the Supreme Court, victims in securities fraud cases should have a longer period to file a claim – from when the fraud was discovered. “Most of us do not live in a state of constant investigation,” the court wrote. “Absent any reason to think we have been injured, we do not typically spend our days looking for evidence that we were lied to or defrauded.”

Chief Justice Roberts explained that “the S.E.C. as enforcer is a far cry from the defrauded victim the discovery rule evolved to protect.” One of the reasons the agency exists is to detect and penalize violations, with tools that the ordinary investor simply does not have, like the authority to compel testimony and the production of documents. The message is simple. When it’s your job to investigate fraud, you cannot argue that your failure to do so is a justification for not meeting a statute of limitations.

The Supreme Court’s decision puts increased pressure on the S.E.C. to pursue its investigations with greater alacrity and not let them gather dust, which can occur as a result of staff turnover or other pressing issues. The market timing case is a good example of how an investigation might get lost in the shuffle as corporate accounting frauds at large companies like Enron and WorldCom, which also came to light in 2002, strained the S.E.C.’s investigative resources.

There are a couple of options to deal with this issue in the long run, apart from a substantial increase in the agency’s budget – an unlikely prospect in the face of the looming federal budget sequestration deadline.

The S.E.C. can obtain an agreement to stop the statute of limitations, known as tolling, from those it is investigating, something it has done in the past. For example, in its insider trading and securities fraud case against Samuel E. Wyly, his now deceased brother, Charles J. Wyly Jr., and two other defendants, the S.E.C. got an agreement that let it pursue claims beyond the normal five-year limitations period.

A permanent solution would be to seek legislation from Congress that would give the S.E.C. a longer window to complete its investigations. The statute of limitations is not a constitutional protection, so Congress can amend it as it sees fit, which it has done in other areas involving fraud.

The limitations period for banking crimes, for example, was extended to 10 years during the savings and loan crisis because of the crush of cases that made it difficult to finish investigations in the five-year window to initiate criminal prosecutions. The Fraud Enforcement and Recovery Act of 2009 added mail and wire fraud affecting a financial institution to the list of crimes that get the benefit of the 10-year limitations period, again because of fear that cases would be lost because of the number of investigations taking place after the financial crisis.

The issue of the statute of limitations may even come up at the confirmation hearings of Mary Jo White, who has been nominated to be chairwoman of the S.E.C. That could be an early indicator of whether she would be willing to push for relief from the effect of the Gabelli opinion to help out the enforcement division.

In the short run, the Supreme Court’s decision will cause defendants in government enforcement actions to examine whether they might be able to take advantage of the five-year limitations period. Given how slowly the government has been known to move on occasion, it may be that some cases will fall by the wayside because of the Gabelli decision.

Study Finds Genetic Risk Factors Shared by 5 Psychiatric Disorders

Their study, published online Wednesday in the Lancet, was based on an examination of genetic data from more than 60,000 people world-wide. Its authors say it is the largest genetic study yet of psychiatric disorders. The findings strengthen an emerging view of mental illness that aims to make diagnoses based on the genetic aberrations underlying diseases instead of on the disease symptoms.

Two of the aberrations discovered in the new study were in genes used in a major signaling system in the brain, giving clues to processes that might go awry and suggestions of how to treat the diseases.

“What we identified here is probably just the tip of an iceberg,” said Dr. Jordan Smoller, lead author of the paper and a professor of psychiatry at Harvard Medical School and Massachusetts General Hospital. “As these studies grow we expect to find additional genes that might overlap.”

The new study does not mean that the genetics of psychiatric disorders are simple. Researchers say there seem to be hundreds of genes involved and the gene variations discovered in the new study only confer a small risk of psychiatric disease.

Steven McCarroll, director of genetics for the Stanley Center for Psychiatric Research at the Broad Institute of Harvard and M.I.T., said it was significant that the researchers had found common genetic factors that pointed to a specific signaling system.

“It is very important that these were not just random hits on the dartboard of the genome,” said Dr. McCarroll, who was not involved in the new study.

The work began in 2007 when a large group of researchers began investigating genetic data generated by studies in 19 countries and including 33,332 people with psychiatric illnesses and 27,888 people free of the illnesses for comparison. The researchers studied scans of peoples’ DNA, looking for variations in any of several million places along the long stretch of genetic material containing three billion DNA letters. The question: Did people with psychiatric illnesses tend to have a distinctive DNA pattern in any of those locations?

Researchers had already seen some clues of overlapping genetic effects in identical twins. One twin might have schizophrenia while the other had bipolar disorder. About six years ago, around the time the new study began, researchers had examined the genes of a few rare families in which psychiatric disorders seemed especially prevalent. They found a few unusual disruptions of chromosomes that were linked to psychiatric illnesses. But what surprised them was that while one person with the aberration might get one disorder a relative with the same mutation got a different one.

Jonathan Sebat, chief of the Beyster Center for Molecular Genomics of Neuropsychiatric Diseases at the University of California, San Diego, and one of the discoverers of this effect, said that work on these rare genetic aberrations had opened his eyes. “Two different diagnoses can have the same genetic risk factor,” he said.

In fact, the new paper reports, distinguishing psychiatric diseases by their symptoms has long been difficult. Autism, for example, at was once called childhood schizophrenia. It was not until the 1970s that autism was distinguished as a separate disorder.

But, Dr. Sebat, who did not work on the new study, said that until now it was not clear whether the rare families he and others had studied were an exception or whether they were pointing to a rule about multiple disorders arising from a single genetic glitch.

“No one had systematically looked at the common variations,” in DNA, he said. “We didn’t know if this was particularly true for rare mutations or if it would be true for all genetic risk.” The new study, he said, “shows all genetic risk is of this nature.”

The new study found four DNA regions that conferred a small risk of psychiatric disorders. For two of them, it is not clear what genes are involved or what they do, said Dr. Smoller. The other two, though, involve genes that are part of calcium channels, which are used when nerves send signals in the brain.

“The calcium channel findings suggest that perhaps – and this is a big if – treatments to affect calcium channel functioning might have effects across a range of disorders,” Dr. Smoller said.

There are drugs on the market that block calcium channels – they are used to treat high blood pressure – and researchers had already postulated that they might be useful for bipolar disorder even before the current findings.

One investigator, Dr. Roy Perlis of Massachusetts General Hospital, just completed a small study of a calcium channel blocker in 10 people with bipolar disorder and is about to expand it to a large randomized clinical trial. He also wants to study the drug in people with schizophrenia, in light of the new findings. He cautions, though, that people should not rush out to take a calcium channel blocker on their own.

“We need to be sure it is safe and we need to be sure it works,” Dr. Perlis said.

Bits Blog: One on One: Sugata Mitra, 2013 TED Prize Winner

Are teachers keeping students from learning in the digital age? Sugata Mitra, a professor of educational technology at Newcastle University, believes so. Dr. Mitra is best known for an experiment in which he carved a hole from his research center in Delhi into an adjacent slum, placing a freely accessible computer there for children to use.

The children quickly taught themselves basic computer skills. The “hole in the wall” experiment, as it is known, led Dr. Mitra to develop the idea of learning environments in which teachers would merely be supervisors as children taught themselves by working together at computer terminals. On Tuesday Dr. Mitra was given the 2013 TED Prize, which grants him $1 million to build a learning laboratory based on this principle.

Q.

What did you learn from the original “hole in the wall” experiment?

A.

The first thing to point out is that it was done 14 years ago, at a time when few children in India had access to computers. I noticed the rich parents saying that their sons and daughters must be gifted, because they were so good with computers. And since we know that gifted kids are not born only to rich parents, why would there not be similar children in the slums? I was curious to see what would happen if I gave an Internet-connected computer to the kind of kids who never had one.

We noticed that they learned how to surf within hours. It was a bit of a surprise. Long story short, they would teach themselves whatever they had to to use the computer, such was the attraction of the machine.

Q.

What does this mean for education?

A.

In those days, the main question was what does it mean for training, because back then people were trained to use computers. So I said it looks like we don’t have to do that.

But I got curious about the fact that the children were teaching themselves a smattering of English. So I started doing a whole range of experiments, and I found that if you left them alone, working in groups, they could learn almost anything once they’ve gotten used to the fact that you can research on the Internet. This was done between 2000 and 2006.

I came to England in 2006, and the schools said, why aren’t you doing it here? So I did, and I realized that what I’ve got has nothing to do with poor children. It probably is just a new way in which children learn in this new environment. It needs two things. First, broadband. That’s fine, everybody loves that. The second thing is, it needs the teacher to stand back.

At first I thought that the children were learning in spite of the teacher not interfering. But I changed my opinion, and realized this was happening because the teacher was not interfering. At that point, I didn’t become entirely popular with teachers. But I explained to them that the job has changed. You ask the right kind of question, then you stand back and let the learning happen.

Q.

Do schools need to be radically changed to implement this, or is this a technique that fits into the current structure of schools?

A.

At the moment I pitch it as a technique that you can bring into your schools. But that’s not the real story, which is that the current schooling system is a leftover from the Victorian age of empire. In that world, there were no computers, no telegraphs and data was carried around on ships. This meant that the pillars of education were reading, writing and arithmetic. That age is gone. The system was wonderfully engineered, but we don’t need it anymore; we need something else. But you can’t just say that without saying how you do it.

What I’m doing is I’m putting my foot in the door by saying here’s a new way. Try it. If you’re happy with it, then I’ll say let’s look at the curriculum top to bottom. If we can convert the curriculum into big questions, if we can turn assessment into peer assessment, then neurophysiology tells us that learning gets enhanced. Finally, if you add admiration — what I call the grandmother’s method, where you stand behind and encourage them. Put all of this together and you get a new way to do schooling.

Q.

So it seems that you’re saying we don’t need teachers at all.

A.

We need teachers to do different things. The teacher has to ask the question, and tell the children what they have learned. She comes in at the two ends, a cap at the end and a starter at the beginning.

Teachers are not supposed to be repositories of information which they dish out. That is from an age when there were no other repositories of information, other than books or teachers, neither of which were portable. A lot of my big task is retraining these teachers. Now they have to watch as children learn.

Q.

Is there a problem with this in that it will serve the good students well, but leave those who need more coaching behind?

A.

Well, yes, to some extent. But there are some interesting things about children working in groups if those groups are self-made. Once you let children do that, the system has a self-correcting ability. Having said that, will there be good students and bad students? Of course.

Q.

Does this work for all levels of instruction?

A.

It doesn’t work the same way with adolescents, and definitely not with adults. With 8- to 12-year-olds, that’s the age where big questions turn them on.

Q.

What are your specific plans with the prize?

A.

In order to see if this sort of self-organized learning environment is suitable I need to have one in which I have some control over and can do measurements with. So I want to build one of these learning spaces somewhere.

It will be totally automatic, completely controlled from the cloud. There will be a supervisor, but that person is not going to be a computer expert or a teacher in anything. She — and it will probably be a she — will be there only for health and safety requirements.

The rest of the school, if we call it a school, is a facility that I can hand over to a mediator from the cloud. She logs in from her home, wherever her home is, and she’s able to control everything inside, the lights, the air-conditioning, you name it. Then there are four mediators who Skype in and use the pedagogical method. That’s going to take a lot of work.

The second bit is that schools all over the world have been using this method. We need to do a massive multiplication, and TED is going to help me do that. I am going to try to put that into homes; get your children and their friends together. Then, every time they do it, I’ll ask them to collect data and send it to a Web site. If I succeed, in two years I’ll have massive data from all over the world. By that time I’ll be done building the facility and I’ll be ready to build a new model.

Q.

Where do you think this school will be?

A.

I’d like to do it in India, because I’d know how to get it done. There will be less of a learning curve, I know who the contractors are, and I know how not to get cheated. So I’d like to do it there, but it’s not set in stone.

Way of the World: When Supercitizens Pull Up the Opportunity Ladder

MIAMI — Louis D. Brandeis, the American jurist, famously warned: “We may have democracy, or we may have wealth concentrated in the hands of a few, but we can’t have both.”

Brandeis’s cri de coeur was inspired by an indignant observation of the shenanigans of America’s robber barons during the Gilded Age. Today, we live in a data-driven age, and some careful students of the connection between money and politics have now amassed a powerful body of evidence to support Brandeis’s moral claim. A lot of it is assembled in a report by the progressive research organization Demos, published this week.

One of the most striking findings is the extent to which economic power translates into political power.

Institutionally, this is an era of unprecedented democracy — one of the triumphs of the 20th century has been the extension of voting rights to all adults in a lot of the world.

But even in the United States, the country that thinks of itself as being the world’s leading democracy, it turns out that those rights do not translate into much actual political power. David Callahan, co-author of “Stacked Deck,” the Demos report, describes the superrich as “supercitizens, with an outsized footprint in the public square.”

“I think most Americans believe in the idea of political equality,” Dr. Callahan told me. “That idea is obviously corrupted when in 2012, one guy, Sheldon Adelson, can make more political donations than the residents of 12 states put together.”

The Demos study draws in part on the quantitative research of Martin Gilens, a professor of politics at Princeton University, in New Jersey, and author of “Affluence and Influence: Economic Inequality and Political Power in America.” Dr. Gilens, who focused on the divide between the top 10 percent and everyone else, found a high degree of what he calls political inequality.

“I looked at lots of survey data that indicated what people at different income levels wanted the government to do, and then I looked at what the government did,” Dr. Gilens explained.

“For people at the top 10 percent, you could predict what the government would do based on their preferences,” he said. “But when the preferences of people at lower income levels diverged from the affluent, that had no impact at all on the policies that were adopted. That was true not only for the poor but for the middle class as well.”

Dr. Gilens is a social scientist who is careful to stick to his data. But he told me he was “definitely surprised by the extent of the inequality.”

“If you value democracy, if you value the ability of people at all levels of income to shape government, which is what it means to be a democracy, then, yes, you should be very worried,” he said.

One reason this “political inequality” is significant is that it turns out the rich and the rest have different political preferences. These do not split easily along traditional partisan lines — in fact, one of Dr. Gilens’s findings is that political inequality persists whether Democrats or Republicans are in charge. And in certain areas, like defense policy, there is no class divide.

But on an important set of economic issues — deficit reduction, the minimum wage, free trade, regulation and progressive taxation — the affluent are more conservative than everyone else.

“None of this might matter if the wealthy and the rest of the public had the same public policy preferences,” Dr. Callahan said. “But as we document, the wealthy do have very different policy preferences, particularly in the sphere of economic and fiscal policy and on trade and globalization. You see this on issues like taxation, or the minimum wage, or the general role of the government in society.”

This gap in policy preferences, the Demos report argues, is the explanation for one of the most puzzling and worrying consequences of rising income inequality — its correlation with falling social mobility. Alan B. Krueger, the head of President Barack Obama’s Council of Economic Advisers, calls this the Great Gatsby Curve, and it is the most compelling reason to be worried about the growing chasm between the top and everyone else.

That link, which has best been documented by the Canadian economist Miles Corak, is mysterious. After all, a lot of today’s rising inequality has been driven by benign forces like the technology revolution and, as a result, today’s plutocrats are more likely to be self-made than they were three decades ago.

But once they become rich supercitizens, the Demos report argues, those at the top of the economic heap use their power to support policies that diminish social mobility. This is not because of malign intent — there is no cabal of fat cats in top hats smoking cigars and plotting how to keep the proletariat down. Indeed, education, a key to social mobility, is a stated priority for the affluent.

The catch comes when there is a choice between personal self-interest, often in the form of lower taxes, and the expensive institutions of greater social mobility. And that is when the supercitizens opt to pull up the opportunity ladder behind them.

Beyond the campus green, Americans can be squeamish about viewing policy choices through the prism of economic self-interest. It is much more comforting to imagine the country is engaged in a high-minded and technocratic debate about what works best to serve the common good.

But that’s not what’s happening. The supercitizens are very effectively pursuing their own self-interest. Social opportunity, and even democracy, are under threat as a result.

State of the Art: A Review of Cookoo, G-Shock and Other Smartwatches

Clockwise from top left: The Cookoo, I'm Watch, Meta Watch, Casio G-Shock GB-6900 and Martian.

Every time you look, our computers have moved closer to us.

In the beginning, they existed only in corporate headquarters. Then came the desktop PC — three feet away. Then the laptop — one foot. Then the smartphone — in our pockets. What’s next — computers on our wrists?

Exactly. As though by silent agreement, the gadget industry seems to have decided that 2013 will be the year of the smartwatch.

The central idea is sound. You already have an iPhone or Android phone. Wouldn’t it be neat if your watch could communicate with it wirelessly?

Imagine: the watch could beep or vibrate whenever you get an incoming call, text message or e-mail. No more, “Sorry I didn’t get your call; my phone was in my backpack.” No more fumbling for your phone when that would be inconvenient or unsafe — like while you’re skiing, skateboarding or driving.

These watches can also make your phone beep loudly when it’s lost in the house. That’s much quicker than using Find My iPhone, which involves logging into a Web site.

They can also serve as a digital “leash”: if you wander away, accidentally leaving your phone on some restaurant table, the watch buzzes to warn you.

I tested the Meta Watch ($180), Cookoo ($130), Casio G-Shock GB-6900 ($180), Martian ($300), and I’m Watch ($400, coming in July). More contenders, like a Kickstarter favorite, Pebble Watch, are on the way. (The Martian, Cookoo and Meta Watch also began life on Kickstarter, the Web site where inventors seek financing from the public.) Even Apple is said to be toying with an iWatch.

The designs are all over the map. Some have touch screens. Some look like regular analog watches; others are basically iPod Nanos with straps. Some require daily charging; others take watch batteries.

They do have some things in common. First, these early smartwatches are thick and chunky — a desirable quality in a stew, maybe, but not for the delicate of wrist.

Second, they communicate with your phone over Bluetooth. You have to “pair” the watch to your phone on the first day — and whenever you exit Airplane Mode. Most models require a companion phone app for this purpose.

Most of these watches use Bluetooth 4.0, which means your phone will lose only a small amount of battery charge each day — maybe 5 or 10 percent — but only recent models, like the iPhone 4S and 5, are compatible.

Finally, the instruction manuals are terrible or nonexistent; it’s as if, in their zeal to make these things work, the companies forgot all about explaining it to you.

Wrists ready? Here we go.

CASIO G-SHOCK GB-6900 ($180). This watch closely resembles Casio’s other G-Shocks: popular, masculine, rugged, waterproof digitals.

But this one can beep or vibrate when calls or e-mail come to your iPhone (Android is in the works) — though not, alas, text messages. There’s no Caller ID; a cramped scrolling display says only “Incoming call.” For e-mail, the sender’s address scrolls slowly. You can dismiss these alerts with a double-tap on the glass — that’s the only thing this watch’s “touch screen” does.

The watch can also set itself as you cross time zones by checking in with your phone.

These limited functions are solid and power-stingy; one watch battery lasts two years. The watch has four buttons — the usual user-hostile digital watch assortment, like Mode, Adjust and Split/Reset — but they get the job done.

COOKOO WATCH ($130). The round face and analog hands offer spartan good looks; only the watch’s alarming thickness (three-quarters of an inch) and four edge buttons let you know that it’s not a Swatch.

There’s no screen. Instead, icons dimly appear on the watch’s black background as notifications of incoming calls, calendar reminders or Facebook posts. (E-mail and text notifications are coming soon, says the company.) If you want to know what they are or who they’re from, you have to get out your phone.

Personal Health: Too Many Pills in Pregnancy

The thalidomide disaster of the early 1960s left thousands of babies with deformed limbs because their mothers innocently took a sleeping pill thought to be safe during pregnancy,

In its well-publicized wake, countless pregnant women avoided all medications, fearing that any drug they took could jeopardize their babies’ development.

I was terrified in December 1968 when, during the first weeks of my pregnancy, I developed double pneumonia and was treated with antibiotics and codeine. Before swallowing a single dose, I called my obstetrician, who told me to take what was prescribed, “reassuring” me that if I died of pneumonia I wouldn’t have a baby at all.

In the decades that followed, pregnancy-related hazards were linked to many medicinal substances: prescription and over-the-counter drugs and herbal remedies, as well as abused drugs and even some vitamins.

Now, however, the latest findings about drug use during pregnancy have ignited new concerns among experts who monitor the effects of medications on the developing fetus and pregnancy itself.

During the last 30 years, use of prescription drugs during the first trimester of pregnancy, when fetal organs are forming, has grown by more than 60 percent.

About 90 percent of pregnant women take at least one medication, and 70 percent take at least one prescription drug, according to the Centers for Disease Control and Prevention.

Since the late 1970s, the proportion of pregnant women taking four or more medications has more than doubled.

Nearly one woman in 10 takes an herbal remedy during the first trimester.

A growing number of pregnant women, naïvely assuming safety, self-medicate with over-the-counter drugs that were once sold only by prescription.

While many commonly taken medications are considered safe for unborn babies, the Food and Drug Administration estimates that 10 percent or more of birth defects result from medications taken during pregnancy. “We seem to have forgotten as a society that drugs pose risks,” Dr. Allen A. Mitchell, professor of epidemiology and pediatrics at Boston University Schools of Public Health and Medicine, said in an interview. “Many over-the-counter drugs were grandfathered in with no studies of their possible effects during pregnancy.”

Medical progress has contributed to the rising use of medications during pregnancy, Dr. Mitchell said. Various conditions, like depression, are now recognized as diseases that warrant treatment; drugs have been developed to treat conditions for which no treatment was previously available, and some conditions, like Type 2 diabetes and hypertension, have become more prevalent.

Misled by the Web

Now a new concern has surfaced: Bypassing their doctors, more and more women are using the Internet to determine whether the medication they are taking or are about to take is safe for an unborn baby.

A study, published online last month in Pharmacoepidemiology and Drug Safety, of so-called “safe lists for medications in pregnancy” found at 25 Web sites revealed glaring inconsistencies and sometimes false reassurances or alarms based on “inadequate evidence.”

The report was prepared by Cheryl S. Broussard of the Centers for Disease Control and Prevention with co-authors from Emory, Georgia State University, the University of British Columbia and the Food and Drug Administration.

“Among medications approved for use in the U.S.A. from 2000 to 2010, over 79% had no published human data on which to assess teratogenic risk (potential to cause birth defects), and 98% had insufficient published data to characterize such risk,” the authors wrote.

But that did not stop the 25 Web sites from characterizing 245 medications as “safe” for use by pregnant women, which “might encourage use of medications during pregnancy even when they are not necessary,” the authors suggested.

Furthermore, the information found online was sometimes contradictory. “Twenty-two of the products listed as safe by one or more sites were stated not to be safe by one or more of the other sites,” the study found.

The question of timing was often ignored. A drug that could interfere with fetal organ development might be safe to take later in pregnancy. Or one (for example, ibuprofen) that is safe early in pregnancy could become a hazard later if it raises the risk of excessive bleeding or premature delivery.

Fewer than half the sites advised taking medication only when necessary, and only 13 sites encouraged pregnant women to consult their doctors before stopping or starting a medication.

Doctors, too, are often poorly informed about pregnancy-related hazards of various medications, the authors noted. One woman I know was advised to wean off an antidepressant before she became pregnant, but another was told to continue taking the same drug throughout her pregnancy.

“In many instances the best bet is for mom to stay on her medication,” said Dr. Siobhan M. Dolan, an obstetrician and geneticist at Albert Einstein College of Medicine. She said that if a woman is depressed during pregnancy, her risk of postpartum depression is greater and she may have difficulty bonding with her baby.

Dr. Dolan, who is author, with Alice Lesch Kelly, of the March of Dimes’ newest book, “Healthy Mom Healthy Baby,” emphasized the importance of weighing benefits and risks in deciding whether to take medication during pregnancy and which drugs to take.

“In anticipation of pregnancy, a woman taking more than one drug to treat her condition should try to get down to a single agent,” Dr. Dolan said in an interview. “Of the various medications available to treat a condition, is there a best choice — one least likely to cause a problem for either the baby or the mother?”

She cautioned against sharing medications prescribed for someone else and assuming that a remedy labeled “natural” or “herbal” is safe. Virtually none have been tested for safety in pregnancy.

Among medications a woman should be certain to avoid, in some cases starting three months before becoming pregnant, are isotretinoin (Accutane and others) for acne; valproic acid for seizure disorders; lithium for bipolar disorder; tetracycline for infections, and angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor antagonists for hypertension, Dr. Dolan said.

“Many medications that are not recommended during pregnancy can be replaced with low-risk alternatives,” she wrote.

Dr. Broussard, who did the “safe lists” study, said in an interview, “We’ve heard about women seeing medications on these lists and deciding on their own that it’s O.K. to take them. “Women who are pregnant or even thinking about getting pregnant should talk directly to their doctors before taking anything. They should be sure they’re taking only what’s necessary for their health condition.”

A reliable online resource for both women and their doctors, Dr. Mitchell said, are fact sheets prepared by OTIS, the Organization of Teratology Information Specialists, which are continually updated as new facts become available: http://www.otispregnancy.org.
