Well: Keeping Blood Pressure in Check

Since the start of the 21st century, Americans have made great progress in controlling high blood pressure, though it remains a leading cause of heart attacks, strokes, congestive heart failure and kidney disease.

Now 48 percent of the more than 76 million adults with hypertension have it under control, up from 29 percent in 2000.

But that means more than half, including many receiving treatment, have blood pressure that remains too high to be healthy. (A normal blood pressure is lower than 120 over 80.) With a plethora of drugs available to normalize blood pressure, why are so many people still at increased risk of disease, disability and premature death? Hypertension experts offer a few common, and correctable, reasons:

¶ About 20 percent of affected adults don’t know they have high blood pressure, perhaps because they never or rarely see a doctor who checks their pressure.

¶ Of the 80 percent who are aware of their condition, some don’t appreciate how serious it can be and fail to get treated, even when their doctors say they should.

¶ Some who have been treated develop bothersome side effects, causing them to abandon therapy or to use it haphazardly.

¶ Many others do little to change lifestyle factors, like obesity, lack of exercise and a high-salt diet, that can make hypertension harder to control.

Dr. Samuel J. Mann, a hypertension specialist and professor of clinical medicine at Weill-Cornell Medical College, adds another factor that may be the most important. Of the 71 percent of people with hypertension who are currently being treated, too many are taking the wrong drugs or the wrong dosages of the right ones.

Dr. Mann, author of “Hypertension and You: Old Drugs, New Drugs, and the Right Drugs for Your High Blood Pressure,” says that doctors should take into account the underlying causes of each patient’s blood pressure problem and the side effects that may prompt patients to abandon therapy. He has found that when treatment is tailored to the individual, nearly all cases of high blood pressure can be brought and kept under control with available drugs.

Plus, he said in an interview, it can be done with minimal, if any, side effects and at a reasonable cost.

“For most people, no new drugs need to be developed,” Dr. Mann said. “What we need, in terms of medication, is already out there. We just need to use it better.”

But many doctors who are generalists do not understand the “intricacies and nuances” of the dozens of available medications to determine which is appropriate to a certain patient.

“Prescribing the same medication to patient after patient just does not cut it,” Dr. Mann wrote in his book.

The trick to prescribing the best treatment for each patient is to first determine which of three mechanisms, or combination of mechanisms, is responsible for a patient’s hypertension, he said.

¶ Salt-sensitive hypertension, more common in older people and African-Americans, responds well to diuretics and calcium channel blockers.

¶ Hypertension driven by the kidney hormone renin responds best to ACE inhibitors and angiotensin receptor blockers, as well as direct renin inhibitors and beta-blockers.

¶ Neurogenic hypertension is a product of the sympathetic nervous system and is best treated with beta-blockers, alpha-blockers and drugs like clonidine.

According to Dr. Mann, neurogenic hypertension results from repressed emotions. He has found that many patients with it suffered trauma early in life or abuse. They seem calm and content on the surface but continually suppress their distress, he said.

One of Dr. Mann’s patients had had high blood pressure since her late 20s that remained well-controlled by the three drugs her family doctor prescribed. Then in her 40s, periodic checks showed it was often too high. When taking more of the prescribed medication did not result in lasting control, she sought Dr. Mann’s help.

After a thorough work-up, he said she had a textbook case of neurogenic hypertension, was taking too much medication and needed different drugs. Her condition soon became far better managed, with side effects she could easily tolerate, and she no longer feared she would die young of a heart attack or stroke.

But most patients should not have to consult a specialist. They can be well-treated by an internist or family physician who approaches the condition systematically, Dr. Mann said. Patients should be started on low doses of one or more drugs, including a diuretic; the dosage or number of drugs can be slowly increased as needed to achieve a normal pressure.

Specialists, he said, are most useful for treating the 10 percent to 15 percent of patients with so-called resistant hypertension that remains uncontrolled despite treatment with three drugs, including a diuretic, and for those whose treatment is effective but causing distressing side effects.

Hypertension sometimes fails to respond to routine care, he noted, because it results from an underlying medical problem that needs to be addressed.

“Some patients are on a lot of blood pressure drugs — four or five — who probably don’t need so many, and if they do, the question is why,” Dr. Mann said.

Stanley Karnow, Historian and Journalist, Is Dead at 87

Stanley Karnow, a Pulitzer Prize-winning historian and journalist who produced acclaimed books and television documentaries about Vietnam and the Philippines in the throes of war and upheaval, died on Sunday at his home in Potomac, Md. He was 87.

The cause was congestive heart failure, said Mr. Karnow’s son, Michael.

For more than three decades Mr. Karnow was a correspondent in Southeast Asia, working for Time, Life, The Saturday Evening Post, The Washington Post, NBC News, The New Republic, King Features Syndicate and the Public Broadcasting Service. But he was best known for his books and documentaries.

He was in Vietnam in 1959, when the first American advisers were killed, and lingered long after the guns fell silent, talking to fighters, villagers, refugees, North and South Vietnamese political and military leaders, the French and the Americans, researching a people and a war that had been little understood.

The result was the 750-page book “Vietnam: A History,” published in 1983, and its companion, a 13-hour PBS documentary, “Vietnam: A Television History.” Unlike many books and films on Vietnam in the 1960s and ’70s and the nightly newscasts that focused primarily on America’s role and its consequences at home and abroad, Mr. Karnow addressed all sides of the conflict and traced Vietnam’s culture and history.

“Vietnam: A History” was widely praised and a best seller. The documentary, with Mr. Karnow as chief correspondent, was at the time the most successful ever produced by public television, viewed by an average of nearly 10 million people a night through 13 episodes. It won six Emmy Awards, as well as Peabody, Polk and duPont-Columbia awards.

Six years later, Mr. Karnow delivered his second comprehensive book and television examination of a Southeast Asian nation. The book, “In Our Image: America’s Empire in the Philippines” (1989), was a panorama of centuries of Filipino life under Spanish and American colonial rule, followed by independence under sometimes corrupt American-backed leaders. It won the 1990 Pulitzer Prize for history.

Narrated by Mr. Karnow, the three-part PBS documentary “The U.S. and the Philippines: In Our Image” traced America’s paternalistic colonial rule in the Philippines, the shared suffering of Filipinos and Americans under a cruel Japanese occupation in World War II, and Manila’s postwar independence under regimes nominally democratic but repressive, corrupt or indifferent to the miseries of its people.

Mr. Karnow also wrote “Mao and China: From Revolution to Revolution” (1972) and was a co-author of or contributor to books based on his years in Asia, including “Asian-Americans in Transition” (1992), “Passage to Vietnam” (1994), “Mekong” (1995) and “Historical Atlas of the Vietnam War” (1995).

Early in his career he lived in Paris for a decade, and in 1997 he published a memoir, “Paris in the Fifties.” A nostalgic reporter’s notebook of life among the cafe philosophers, berated musicians and pseudo-revolutionary artistes, it danced with digressions about taxes, restaurants, the guillotine, Hemingway, Charles de Gaulle and the Devil’s Island penal colony.

In its range, learning and appetite for fun, Bernard Kalb, the former CBS reporter and Mr. Karnow’s friend since Vietnam, told The Associated Press in 2009, the memoir was vintage Karnow. “Stanley has a great line about how being a journalist is like being an adolescent all your life,” he said.

Stanley Karnow was born in Brooklyn on Feb. 4, 1925, the son of Harry and Henriette Koeppel Karnow. He grew up in a city with more than a dozen daily newspapers and decided early that he wanted to become a reporter. He served in the Army Air Forces in World War II. After graduating from Harvard with a bachelor’s degree in 1947, he sailed for France, intending to spend the summer. He stayed for a decade.

This article has been revised to reflect the following correction:

Correction: January 28, 2013

An earlier version of this article misstated the year in which Stanley Karnow was a Nieman Fellow at Harvard University. It was 1958, not 2002. The article also misspelled the name of the Nieman Fellowship.

India Ink: Scattered Protests in Delhi on Republic Day

Several groups of protesters marched and demonstrated in New Delhi on Saturday as India celebrated its 64^th Republic Day, demanding better safety for women, a movement that started after the Dec. 16 gang rape of a young woman here.

A march of several hundred students, organized by the All India Students’ Association, sat on the street at Jantar Mantar, a designated protest area in central Delhi. The protesters carried the placards bearing slogans including, “No Violence Against Women,”l “Unknown Citizen,” and “Freedom Without Fear.” They shouted slogans including, “We Want Justice” and “Rajpath is yours. Janpath is ours.” (Rajpath is the street where the official Republic Day parade passes and Janpath is where the protesters began their march.)

“We want to counter the notion that women are safe inside. We want women to be safe outside,” said Oshin Siao Bhatt, a student at Miranda House College of Delhi University who attended.

“In 2012 only one rapist was convicted in Delhi while about 600 rapes took place,” Shafaq Khan, a philosophy student at Jawaharlal Nehru University said. “We want to reclaim our republic.”

At another rally organized by the Progressive Democratic Student Union, protesters’ placards proclaimed: “Respect The Sex Which Gave You Birth” and  “Punish The Police, Sensitize Judiciary, Eradicate Rape.”

At a third, placards read, “We Want Safety, Not Compensation,” referring to the money given by government to the family of the rape victim, and “We Want Justice Not Dates,” referring to the judicial delays.

At a fourth protest rally, an activist, Arvind Kejriwal, who has formed the Aam Admi, or Common Men, party to run for election, told a crowd that if the right people enter into politics, violence against women will decline. One small group of protesters had created a funeral pyre that they said represented the Delhi rape victim, and said they would not move themselves until the rapists were hanged.

Japan to start 4K TV broadcast in July 2014: report

TOKYO (Reuters) – The Japanese government is set to launch the world’s first 4K TV broadcast in July 2014, roughly two years ahead of schedule, to help stir demand for ultra high-definition televisions, the Asahi newspaper reported on Sunday without citing sources.

The service will begin from communications satellites, followed by satellite broadcasting and ground digital broadcasting, the report said.

The 4K TVs, which boast four times the resolution of current high-definition TVs, are now on sale by Japanese makers including Sony Corp , Panasonic and Sharp Corp . Other manufacturers include South Korea’s LG Electronics .

Japan’s Ministry of Internal Affairs and Communications had aimed to kick-start the 4K TV service in 2016. That has been brought forward to July 2014, when the final match of the 2014 football World Cup is set to take place in Brazil, the Asahi report said.

In Japan, the development of super high-definition 8K TVs is in progress, and the Ministry of Internal Affairs and Communications plans to launch the test 8K TV broadcast in 2016, two years ahead of schedule, it said.

In New Orleans, an unwelcome mat for Goodell

NEW ORLEANS (AP) — An effigy of NFL Commissioner Roger Goodell dangles from the front porch of a New Orleans home that is otherwise festively decorated with Saints paraphernalia.

With restaurants and bars gearing up for an influx of Super Bowl XLVII visitors, the "Refuse to Serve Roger Goodell" page on Facebook had 107 likes as of Friday.

A portrait of Goodell covers the bull's-eye on the dart board at Parkview Tavern.

And floats in the unabashedly lowbrow Krewe du Vieux parade in the French Quarter last weekend displayed larger-than-life likenesses of Goodell in acts that defy polite description.

New Orleans is celebrating the return of Saints coach Sean Payton after a season of NFL banishment as a result of the "bountygate" scandal — when the team ran a pay-for-hits program. But Goodell, who suspended Payton and other current and former Saints players and coaches last year for their roles in the system, is being ridiculed here with a vehemence usually reserved for the city's scandal-scarred politicians.

"They believe he completely used the Saints as an example of something that was going on league-wide," said Pauline Patterson, co-owner of Finn McCool's, an Irish Bar in the Mid-City neighborhood where the words "Go To Hell Goodell" are visible over the fireplace.

Some of Goodell's critics say the disarray resulting from what they believe were unfair suspensions led to the Saints' 7-9 performance this year — and a missed chance to make history.

"We had a real shot of being the first team in history to host the Super Bowl in our own stadium," Parkview Tavern owner Kathy Anderson said. "He can't give that back to us."

Goodell suspended the coaches and players after an investigation found the Saints had a performance pool offering cash rewards for key plays, including big hits. The player suspensions eventually were overturned, but the coaches served their punishments.

Mayor Mitch Landrieu is among those saying that people in this city, known for its hospitality and history, should mind their manners and remember the not-too-distant past.

"Roger Goodell has been a great friend to New Orleans, and it's a fact that he's one of the people instrumental to making sure that the Saints stayed here after Hurricane Katrina," Landrieu said in a statement. It was a reference to the days after the storm, when 80 percent of the city was underwater and the damaged Superdome became a shelter for thousands of the displaced.

Then-Commissioner Paul Tagliabue and his second-in-command, Goodell, are credited with working to keep the team from abandoning New Orleans for San Antonio.

"If not for Roger Goodell, we would not have this Super Bowl," Landrieu added. "And we will need him since we want to host another one."

Saints quarterback Drew Brees said the game is validation of everything the city's gone through to rebuild after Hurricane Katrina.

"There's no question, yeah. And I think people will see that when they come down, as soon as people come down that haven't been there in a while," Brees said Friday while in Hawaii for the Pro Bowl. "The city knows how to entertain, knows how to treat people right. The tourism industry's huge, so we're excited to host this big game. Obviously it's the biggest sporting event in the world, and the city will be ready for it."

But some are in no mood to back off when it comes to Goodell.

Anderson said she understands city leaders' desire to put their best foot forward, but that it also is important for Saints fans to be able to vent.

"Whether I have Roger Goodell's face on my dart board is not going to change anybody's mind about the Super Bowl," Anderson said.

People should not take the barbs too seriously, said Lynda Woolard, a Saints fan who has been tracking some of the barbs on social media. "Nobody's saying there should be violence against the man," Woolard said.

"It's tongue-in-cheek," Patterson agreed.

Still, some diehards are ready to put it all behind them.

Patrick Brower, owner and manager of the Dirty Coast T-shirt shop, said Friday that he's pushing black-and-gold wear at his shop, choosing to unify Saints fans without bashing the commissioner.

"We've got to look forward here," Brower said. "The more time we spend in the past, it's just not beneficial."

Well: Ask Well: Squats for Aging Knees

You are already doing many things right, in terms of taking care of your aging knees. In particular, it sounds as if you are keeping your weight under control. Carrying extra pounds undoubtedly strains knees and contributes to pain and eventually arthritis.

You mention weight training, too, which is also valuable. Sturdy leg muscles, particularly those at the front and back of the thighs, stabilize the knee, says Joseph Hart, an assistant professor of kinesiology and certified athletic trainer at the University of Virginia, who often works with patients with knee pain.

An easy exercise to target those muscles is the squat. Although many of us have heard that squats harm knees, the exercise is actually “quite good for the knees, if you do the squats correctly,” Dr. Hart says. Simply stand with your legs shoulder-width apart and bend your legs until your thighs are almost, but not completely, parallel to the ground. Keep your upper body straight. Don’t bend forward, he says, since that movement can strain the knees. Try to complete 20 squats, using no weight at first. When that becomes easy, Dr. Hart suggests, hold a barbell with weights attached. Or simply clutch a full milk carton, which is my cheapskate’s squats routine.

Straight leg lifts are also useful for knee health. Sit on the floor with your back straight and one leg extended and the other bent toward your chest. In this position, lift the straight leg slightly off the ground and hold for 10 seconds. Repeat 10 to 20 times and then switch legs.

You can also find other exercises that target the knees in this video, “Increasing Knee Stability.”

Of course, before starting any exercise program, consult a physician, especially, Dr. Hart says, if your knees often ache, feel stiff or emit a strange, clicking noise, which could be symptoms of arthritis.

J. Richard Hackman, an Expert in Team Dynamics, Dies at 72

J. Richard Hackman, a Harvard psychology professor whose fieldwork sometimes took him to the cockpit of an airliner to observe the crew in a nearly five-decade quest to determine the dynamics of teamwork and effective leadership, died on Jan. 8 in Boston. He was 72.

The cause was lung cancer, his wife, Judith Dozier Hackman, said.

Dr. Hackman, the author or co-author of 10 books on group dynamics, was the Edgar Pierce professor of social and organizational psychology at Harvard.

In one of his best-known books, “Leading Teams: Setting the Stage for Great Performances” (2002), he replaced the popular image of the powerful “I can do it all” team leader with that of someone who, as he wrote, had the subtle skills “to get a team established on a good trajectory, and then to make small adjustments along the way to help members succeed.”

The conditions for a successful team effort — among them “a compelling direction, an enabling team structure, a supportive organizational context and expert team coaching” — “are easy to remember,” Dr. Hackman wrote.

“The challenge,” he continued, “comes in developing an understanding of those conditions that is deep and nuanced enough to be useful in guiding action, and in devising strategies for creating them even in demanding or team-unfriendly organizational circumstances.”

Besides tracking the interplay of pilots, co-pilots and navigators aboard civilian and military planes, Dr. Hackman observed corporate boards, sports teams, orchestra players, telephone-line repair crews, hospital workers and restaurant kitchen staff members.

And in recent years, for his 2011 book, “Collaborative Intelligence,” he was allowed to observe interactions within the American intelligence, defense, law-enforcement and crisis-management communities.

“Although my main aspiration has been to provide guidance that will be useful to team leaders and members,” he wrote, “there are no ‘one-minute’ prescriptions here — creating, leading and serving on teams is not that simple.”

Anita Woolley, a professor of organizational behavior and theory at the Tepper School of Business at Carnegie Mellon University in Pittsburgh, said, “The key thing about Dr. Hackman’s work is that it stands in contrast to some of the more popular models of leadership that focused very much on style or how leaders behave, versus what they do.”

Rather than viewing pay as a prime motivator for good performance, she continued, “he focused on features of people’s jobs that made them more intrinsically satisfied: the freedom to determine how they conduct their work, having a variety of tasks, having knowledge of the ultimate outcomes of their work, knowing how their work affects or is received by other people.”

He also liked to overturn some of the received wisdom about teamwork. In a 2011 article for The Harvard Business Review, Dr. Hackman listed “Six Common Misperceptions About Teamwork.” Among them was this:

“Misperception No. 2: It’s good to mix it up. New members bring energy and fresh ideas to a team. Without them, members risk becoming complacent, inattentive to changes in the environment, and too forgiving of fellow members’ misbehavior.

“Actually: The longer members stay together as an intact group, the better they do. As unreasonable as this may seem, the research evidence is unambiguous. Whether it is a basketball team or a string quartet, teams that stay together longer play together better.”

John Richard Hackman was born in Joliet, Ill., on June 14, 1940, the only child of J. Edward and Helen Hackman. His father was an oil pipeline engineer, his mother a schoolteacher.

Dr. Hackman received a bachelor’s degree in mathematics from MacMurray College in Jacksonville, Ill., in 1962, and a doctorate in psychology from the University of Illinois in 1966. He soon joined the psychology and administrative sciences department faculties at Yale, where he taught until 1986, when he moved to the psychology and business departments at Harvard.

Besides his wife, who is an associate dean at Yale, he is survived by two daughters, Julia Beth Proffitt and Laura Dianne Codeanne, and four grandchildren.

After Dr. Hackman died, The Harvard Crimson wrote that for years he had “devoted countless hours to improving one team in particular — the Harvard women’s basketball squad, for which he volunteered as an honorary coach.”

Huawei is now the world’s third largest smartphone vendor, but still far behind Samsung and Apple

Research firm IDC released the latest numbers from its Worldwide Quarterly Mobile Phone Tracker this week and found that a total of 482.5 million mobile phones were shipped in the fourth quarter of 2012, an increase from 473.4 million in 2011. Smartphones accounted for nearly half, or 45.5%, of all mobile phone shipments, the highest percentage ever. Samsung (005930) and Apple (AAPL) remained the two top vendors with market shares of 29% and 21.8% respectively. The report did include some surprises, however.

[More from BGR: Sony’s PS Vita: Dead again]

“The high-growth smartphone market, though dominated by Samsung and Apple, still presents ample opportunities for challengers,” said Kevin Restivo, senior research analyst with IDC. “Vendors with unique market advantages, such as lower-cost devices, can rapidly gain market share, especially in emerging markets”

[More from BGR: Unlocking your smartphone will be illegal starting next week]

The remaining top five smartphone vendors are very different now, however — they no longer include LG (006570), HTC (2498) or Motorola, all of which have been replaced by Huawei (002502), Sony (SNE) and ZTE (0763).

Huawei, a company previously known for its telecom equipment, spying scandals and low-end smartphones, is in the midst of a major transition. Rather than focusing on cheap and carrier-branded phones, the Chinese company has begun to compete with high-end manufacturers such as Samsung and Apple with its new flagship devices.

Huawei experienced unprecedented growth in the fourth quarter of 2012 with shipments increasing 89.5% year-over-year for a 4.9% market share. Close on the company’s heels are both Sony and Chinese rival ZTE with 4.5% and 4.3% shares of the market respectively.

“The fact that Huawei and ZTE now find themselves among the Top 5 smartphone vendors marks a significant shift for the global market,” noted Ramon Llamas, research manager with IDC’s Mobile Phone team. “Both companies have grown volumes by focusing on the mass market, but in recent quarters they have turned their attention toward higher-end devices. In addition, both companies have pushed the envelope in terms of industrial design with larger displays and smaller form factors, as well as innovative applications and experiences.”

Armstrong meeting with USADA appears unlikely

AUSTIN, Texas (AP) — Lance Armstrong's lawyers say the cyclist will talk more about drug use in the sport, just likely not to the U.S. Anti-Doping Agency that led the effort to strip him of his Tour de France titles.

In a testy exchange of letters and statements revealing the gulf between the two sides, USADA urged Armstrong to testify under oath to help "clean up cycling."

Armstrong's attorneys responded that the cyclist would rather take his information where it could do more good — namely to cycling's governing body and World Anti-Doping Agency officials.

USADA's response to that: "The time for excuses is over."

The letters, obtained Friday by The Associated Press, underscore the continuing feud between Armstrong and USADA CEO Travis Tygart, the man who spearheaded the investigation that uncovered a complex doping scheme on Armstrong's U.S. Postal Service teams.

Armstrong's seven Tour de France victories were taken away last year and he was banned for life from the sport.

In an interview with Oprah Winfrey last week, Armstrong admitted doping, said he owed a long list of apologies and that he would like to see his lifetime ban reduced so he can compete again.

His most realistic avenue toward that might be telling USADA everything he knows in a series of interviews the agency wants started no later than Feb. 6.

That seems unlikely.

Armstrong attorney Tim Herman responded to USADA's first letter, sent Wednesday, by saying his client's schedule is already full, and besides, "in order to achieve the goal of 'cleaning up cycling,' it must be WADA and the (International Cycling Union) who have overall authority to do so."

By Friday night, Herman strongly suggested Armstrong won't meet with USADA at all but intends to appear before the UCI's planned "truth and reconciliation" commission.

"Why would we cooperate (with USADA)?" Herman said in a telephone interview. "USADA isn't interested in cleaning up cycling. Lance has said, 'I'll be the first guy in the chair when cycling is on trial, truthfully, under oath, in every gory detail.' I think he's going testify where it could actually do some good: With the body that's charged with cleaning up cycling," Herman said.

In its last letter to Armstrong, sent Friday evening, USADA attorney William Bock said his agency and WADA work hand-in-hand in that effort.

"Regardless, and with or without Mr. Armstrong's help, we will move forward with our investigation for the good of clean athletes and the future of sport," Bock's letter reads.

The letters confirm a Dec. 14 meeting in Denver involving Armstrong, Tygart and their respective attorneys, which is when, in Tygart's words, Armstrong should have started thinking about a possible meeting with USADA.

"He has been given a deadline of February 6th to determine whether he plans to come in and be part of the solution," Tygart said in a statement. "Either way, USADA is moving forward with our investigation on behalf of clean athletes."

The letters were sent to the AP after details about a Tygart interview with "60 Minutes," being aired Sunday, were made public.

Among Tygart's claims: Armstrong is lying when he says he didn't dope during his 2009-10 comeback.

Tygart said USADA's report on Armstrong's doping included evidence Armstrong was still cheating in those years.

"His comeback was totally clean," Herman said. "It's pretty fashionable to kick Lance Armstrong around right now."

Tygart also reiterated that an Armstrong associate offered USADA a donation of more than $200,000. Armstrong denied that in his interview with Winfrey, too.

In advancing his claim that USADA is only a bit player in the investigation, Herman noted in his letter, sent to USADA on Friday, that most cycling teams are based in Europe.

"I'm pretty sick of people trying to blame a European cycling culture that goes back to the 1920s on one guy," Herman said.

Bock's response to that: "Your suggestion that there is some other body with which Lance should coordinate is misguided," he said in his final letter.
