Doubts Emerge on the Value of Very Low Cholesterol Levels
Image: frentusha /iStockphoto
From Nature magazine.
Soon after Joseph Francis learned that his levels of ?bad? LDL cholesterol sat at twice the norm, he discovered the short?comings of cholesterol-lowering drugs ? and of the clinical advice guiding their use. Francis, the director of clinical analysis and reporting at the Veterans Health Administration (VA) in Washington DC, started taking Lipitor (atorvastatin), a cholesterol-lowering statin and the best-selling drug in pharmaceutical history. His LDL plummeted, but still hovered just above a target mandated by clinical guidelines. Adding other medications had no effect, and upping the dose of Lipitor made his muscles hurt ? a rare side effect of statins, which can cause muscle breakdown.
So Francis pulled back to moderate Lipitor doses and decided that he could live with his high cholesterol. Later, he learned that other patients were being aggressively treated by doctors chasing stringent LDL targets. But Francis found the science behind the target guidelines to be surprisingly ambiguous. ?You couldn?t necessarily say lowering LDL further was going to benefit the patient,? he says.
The standard advice may soon change. For the first time in more than a decade, the US National Heart, Lung and Blood Institute is revising the clinical guidelines that shaped Francis?s treatment (see ?How low can you go??). Expected to be released later this year, the fourth set of guidelines, called ATP IV, has been drawn up by an expert panel of 15 cardiologists appointed by the institute. The guidelines will set the tone for clinical practice in the United States and beyond, and will profoundly influence pharmaceutical markets. They will also reflect the growing debate over cholesterol targets, which have never been directly tested in clinical trials.
Since 2002, when ATP III called on doctors to push LDL levels below set targets, the concept of low cholesterol has become synonymous with heart health. Patients brag about their cholesterol scores, physicians joke about adding statins to drinking water, and some hospitals reward doctors when patients hit cholesterol targets.
In 2011, US doctors wrote nearly 250 million prescriptions for cholesterol-lowering drugs, creating a US$18.5-billion market, according to IMS Health, a health-care technology and information company based in Danbury, Connecticut. ?The drug industry in particular is very much in favour of target-based measures,? says Joseph Drozda, a cardiologist and director of outcomes research at Mercy Health in Chesterfield, Missouri. ?It drives the use of products.?
ATP III reflected a growing consensus among physicians that sharply lowering cholesterol would lessen the likelihood of heart attacks and strokes, says Richard Cooper, an epidemiologist at the Loyola University of Chicago Stritch School of Medicine in Illinois, who served on the committee that compiled the guidelines. The committee drew heavily on clinical data, but also took extrapolations from basic research and post hoc analyses of clinical trials. LDL targets were set to be ?less than? specific values to send a message, Cooper says. ?We didn?t want to explicitly say ?the lower the better? because there wasn?t evidence for that,? he says. ?But everybody had the strong feeling that was the correct answer.?
By contrast, the ATP IV committee has pledged to hew strictly to the science and to focus on data from randomized clinical trials, says committee chairman Neil Stone, a cardiologist at Northwestern University School of Medicine in Chicago. If so, Krumholz argues, LDL targets will be cast aside because they have never been explicitly tested. Clinical trials have shown repeatedly that statins reduce the risk of heart attack and stroke, but lowering LDL with other medications does not work as well. The benefits of statins may reflect their other effects on the body, including fighting inflammation, another risk factor for heart disease.
Krumholz?s scepticism is rooted in experience. In 2008 and 2010, the Action to Control Cardiovascular Risk in Diabetes (ACCORD) clinical trial challenged dogma when it reported that lowering blood pressure or blood sugar to prespecified targets did not reduce the risk of heart attack or stroke. In the case of blood sugar, the risks were worsened. The trial demonstrated the folly of assuming that risk factors must have a causal role in disease, says Robert Vogel, a cardiologist at the University of Colorado, Denver. ?Short people have a higher risk of heart disease,? he says. ?But wearing high heels does not lower your risk.?
Jay Cohn, a cardiologist at the University of Minnesota Medical School in Minneapolis, also worries that the focus on LDL levels offers up the wrong patients for statin therapy. Most of those who have a heart attack do not have high LDL, he notes. Cohn advocates treating patients with statins based on the state of health of their arteries, as revealed by noninvasive tests such as ultrasound. ?If your arteries and heart are healthy, I don?t care what your LDL or blood pressure is,? he says.
?We can?t just assume that modifying the risk factor is modifying risk.?
Not all cardiologists want to abolish LDL targets. Indeed, Seth Martin, a fellow in cardiology at Johns Hopkins University School of Medicine in Baltimore, Maryland, believes that ATP IV should reduce LDL targets further. The simplicity of targets has helped to deliver an important public-health message, he says, and motivated many patients to get the statin therapy that he believes they need. ?Just to throw that out the window doesn?t seem like the ideal scenario.?
Whatever the decision, the pharmaceutical industry will be watching closely, says Donny Wong, an analyst at Decision Resources, a market-research company based in Watertown, Massachusetts. Although most statins are off patent, the big pharmaceutical companies are racing to bring the next LDL-lowering drug to market. In particular, millions of dollars have been poured into drugs that inhibit a protein called PCSK9, an enzyme involved in cholesterol synthesis. This approach lowers LDL but has not yet been shown to reduce heart attacks or strokes.
Francis expects the new guidelines to relax the targets. He and his colleagues decided last autumn to change the VA?s own clinical standards, so that they no longer rely solely on an LDL target but instead encourage doctors to prescribe a moderate dose of statin when otherwise healthy patients have high LDL cholesterol. The ATP IV guidelines will take a similar approach, he speculates, noting that the VA consulted several outside experts who are also serving on the ATP committee.
Despite an increasingly vegetarian diet, Francis?s cholesterol has not budged. ?Sometimes I want to call my physician and say, ?Don?t worry about that target,?? he says. ?It?s going to be changing very soon.?

Pope in final address: I'm not abandoning the church
Some 50,000 were invited and thousands more came to Pope Benedict XVI's final audience. NBC's Keir Simmons reports.
By Alastair Jamieson, Staff writer, NBC News
Pope Benedict XVI assured a huge, cheering crowd at the Vatican Wednesday that he was not abandoning the Catholic Church, saying he would remain at its service through prayer.
"I ask each of you to pray for me," he told tens of thousands who gathered in the sunshine to watch his?final general audience before Thursday's abdication.
Referring to the many turbulent moments of his papacy, he acknowledged its moments of joy but also difficulty when "It seemed like the Lord was sleeping."
"There were moments when the waters were choppy and there were headwinds," he said.
He said he was not "coming down from the cross" despite renouncing his office, saying his decision was taken "in full awareness of its gravity and rarity but also with profound serenity of spirit."
Greg Burke, a spokesman for the Vatican who was with Pope Benedict XVI just hours earlier, talks about the pope's final audience and his upcoming abdication.
Earlier, pilgrims and onlookers from around the world cheered as Benedict arrived and made a circuit of the square on his "popemobile."
Benedict waved as he swept through the crowd, pausing briefly several times to bless babies, before heading to a platform in front of St. Peter?s Basilica to make his address.
Among the audience was New Yorker Elise O'Donnell-Tixon, who is now living in Rome. "I'm sad because this will likely be the last time I see him," she said. "I was lucky, because my husband and I were blessed by the pope at an audience last Christmas. We got front-row seats."
At the end of the speech, the crowd stood to applaud.
Vatican communications adviser Greg Burke told TODAY that Pope Benedict had appeared to be calm during the speech, despite the emotion of the occasion.
"He has always been very serene," Burke said. "Above all else, he showed he has faith. His message was that it's not our church, it's not my church, it's the church of Christ."

The pope delivers his final audience in St. Peter's Square as he prepares to stand down.
Vatican organizers said?more than 50,000 had applied for official tickets for Wednesday?s event ? eight times the usual number of applications. An estimated total of 200,000 were expected in square and surrounding streets.
The size of the event means there was not expected to be any kissing of the pontiff?s hand as is traditional after papal audiences.
Young members of the Catholic group Opus Dei served as stewards at the entrance to the square, managing the queues of people filing in past metal detectors, AFP correspondent Gildas Le Roux reported.
Not all of them supported Benedict's resignation, Le Roux said, quoting one of the stewards, Leonardo Rossi, as saying: "I do not share the pope's decision to step down. It is not a fitting time, with all the problems the church is going through."
Many in the crowd waved flags and banners wishing the pope well, although the overall tone of the event remained sombre.
Sister Carmela, who lives north of Rome, traveled to the square with her fellow nuns and members of her parish, Reuters said.
"He did what he had to do in his conscience before God," she told Reuters. "This is a day in which we are called to trust in the Lord, a day of hope. There is no room for sadness here today. We have to pray, there are many problems in the Church but we have to trust in the Lord."
Tens of thousands had been in the square since early Wednesday in the hope of securing a good place from which to see the audience.
Among them was a marching band from Pope Benedict?s native Germany. Balthasar Bauer, 23, from Bavaria, who was in traditional dress, lederhosen, said: "This will likely be the last Bavarian pope, so I had to come here to see him for one last time."
After the address, the Pope's Twitter account, @Pontifex, posted a message that said: "If only everyone could experience the joy of being Christian, being loved by God who gave his Son for us!"
Pope Benedict's full 17-minute sermon in Italian, with English translation.
Pope Benedict will leave his residence inside the Vatican and travel by helicopter to his summer residence at Castel Gandolfo, about 15 miles south-east of Rome at about 4.55 p.m. local time (10:55 a.m. ET) Thursday. His papacy will officially end at 8 p.m. local time (2 p.m. ET).
After stepping down, the pope will keep his name, His Holiness Benedict XVI, but get a new official title, "Emeritus Pope." The Vatican on Tuesday said he would wear a simple white cassock and swap his traditional red shoes for a pair of brown leather loafers he was given on his trip to Leon in Mexico last year.
Meanwhile, the Vatican said Wednesday that the date of the conclave to elect Benedict's successor may not be known until after Monday.
Father Federico Lombardi told the Catholic News Service that cardinals eligible to take part cannot set a start date for the conclave until they have met at the Vatican, and that invitations for them to meet will not be sent out by Cardinal Angelo Sodano, dean of the College of Cardinals, until Friday.
NBC News' Carlo Angerer and Andy Eckardt and Reuters contributed to this report.

University of California - Santa Barbara
(Santa Barbara, Calif.) For over a century, the rubber tappers of Acre, Brazil collected the valuable sap of the rubber trees from the forests of the western Amazon. As the demand for natural rubber declined, however, the Brazilian government sought to stimulate the economy in the 1970's by encouraging southern ranchers to bring their cattle to the isolated state and convert the forests to pastureland.
During the dramatic land conflicts that ensued, rubber tappers captured international media attention by arguing that their harvesting of rubber and other products from the standing forest gave them a livelihood, while at the same time contributing to the preservation of the Amazonian rain forest. While much has been written about the internationally celebrated "forest guardian" rubber tappers, few researchers have tried to understand the ranchers, who, in the minds of many, remain the violent and environmentally destructive villains of Amazonia.
In an article titled "Black Hats and Smooth Hands: Elite Status, Environmentalism, and Work Among the Ranchers of Acre, Brazil," UC Santa Barbara anthropologist Jeffrey Hoelle studies the growing cattle industry as it related to rubber tappers, ranchers, and other rural groups. His article, which received the Eric R. Wolf Prize from the Society for the Anthropology of Work, appeared in a recent issue of the journal Anthropology of Work Review.
"Cattle raising is a leading driver of deforestation in the Amazon. It is a very contentious issue, and, in some ways, the ranchers have become the unquestioned bad guys of the region," said Hoelle, an assistant professor of anthropology. "But many rural groups see them as a model of the success and status that they want. No one has ever talked about the meaning of cattle raising, and the meaning of carving out a space within the forest in the Brazilian Amazon.
According to Hoelle, to resolve issues related to land use and deforestation in the Amazon, ranchers must be brought into the dialogue. "As is the case with any Amazonian research, if you want to preserve the rain forest, it makes sense to work with everyone especially those that have the most power." Generating a more nuanced understanding of the ranchers is an essential step in moving toward larger goals of sustainability and rain forest preservation.
Hoelle's research helped him develop that more nuanced understanding. He also found that ranchers aren't the only people who support cattle raising in the Amazon. Others, including rubber tappers, are moving toward that industry because of the economic advantages it offers. "Pastureland is worth more than forest," Hoelle noted, "and rubber is heavy and seasonal. But you can always walk your cow to market, milk it, and use it to carry your forest products." It's hard to compete with cattle raising in Amazonia, he added, noting that production has exploded over the past decade, fueling Brazil's rise to the top of global beef exporting countries.
Through his work, Hoelle also developed a sense of how groups could be opposed to deforestation regulations. According to current Brazilian forest law, ranchers are required to preserve 80 percent of their land as forest. "They don't like government officials telling them what to do with their land, particularly when they feel that the message is really coming from wealthy countries that already cut down much of their own forests," Hoelle said.
He noted that the ranchers are active in campaigns to revise the forest law. "They're just trying to get it to be more fair," he said, "or, to be compensated in some way for the land they can't use. They're told to sacrifice for the good of the world, but many look at North American and European environmentalists and see hypocrites trying to hold them back."
Some of the ranchers, as Hoelle learned through interviews and interaction, did not come to the Amazon as wealthy entrepreneurs, and their opposition to deforestation regulations is based on more than the pursuit of profit. "Many of the ranchers came to Amazonia in the 1970's, at a time when the forest was seen as little more than an obstacle, and they understood their work as pioneers opening the frontier," he said. "Only a few of them were rich when they came; the rest worked hard to get what they have today. I can't speak to the past violence of the ranchers, which was a topic they universally attributed to a few 'bad apples,' but I did come to understand their mindset. They and others quote the bible, talking about how God gave humans the land and the beasts and told them to make it productive. They cite the songs about hard work. For many rural Amazonians not just ranchers leaving the land idle is a sin, and leaving the forest intact is a sign of laziness."
Hoelle said he doesn't defend the ranchers, but he does understand their perspective better now than before he began his research. "Anthropologists and other social scientists are often drawn to the underdog," he explained. "I am no different. I went to Acre initially thinking about the forest-saving rubber tappers, and was prepared to look down my nose at the ranchers. But what good would that do? Finding a balance between environmental preservation, social justice, and economic development requires better understanding the perspectives of all groups living on the land in Amazonia, especially those with the most land, money, and power the ranchers. It also means asking why cattle raising now makes sense to a poor rubber tapper, instead of blaming the ranchers for deforestation. It is complicated, really, and this study is just the beginning."

N. Korea: Nuclear test will keep 'hostile' US at bay

By David Chance, Reuters
SEOUL, South Korea - North Korea has bolstered its defenses against a "hostile" United States with its third nuclear test, it said on Thursday, noting that countries that had bowed to U.S. pressure to abandon their nuclear plans had suffered "tragic consequences."
Pyongyang?carried out its largest nuclear test to date last week, in defiance of U.N. resolutions, prompting warnings of tougher sanctions for the isolated and impoverished state and its young ruler, Kim Jong Un.
Libya abandoned its nuclear program in 2003 in a bid to mend relations with the United States and later saw leader Moammar Gadhafi overthrown in an uprising that was eventually supported militarily by Washington.
North Korea releases a new propaganda video calling the U.S. hostile and showing images of President Obama superimposed with flames. Meanwhile, residents line the streets of Pyongyang celebrating the country's recent nuclear test. NBCNews.com's Dara Brown reports.
In apparent reference to Libya, North Korea said it never backed down.
"The tragic consequences in those countries which abandoned halfway their nuclear programs... clearly prove that the DPRK (Democratic People's Republic of Korea) was very far-sighted and just when it made the (nuclear) option," North Korea's KCNA news agency said.
Kim staged the latest test in response to tighter U.N. sanctions imposed in January after the country launched a long-range rocket last year in a move that critics said was designed to prove technology for an intercontinental ballistic missile.
North Korea has recently stepped up its rhetoric against South Korea, threatening to destroy its rich, democratic neighbor.
Most military assessments suggest that North Korea would lose any war against the U.S.-backed South and that its leaders would not risk a major conflict.

CEDAR PARK: Timberwolves looking for repeat performance
Cedar Park baseball coach Connie Cochrane knows that even with his top pitchers coming back and Lake Travis moving to District 16-5A, the defending District 25-4A champions are anything but a lock for a repeat championship season.
The Timberwolves graduated five starters from the team that went 22-12-1 last season and reached the area round of the Class 4A playoffs, including three infielders and three-year starting catcher Thompson McDougal.
?Frankly, I don?t see a lot of experience coming back when it comes to playing time,? Cochrane said. ?We have some kids who have been on varsity, but have been reserves, who are ready to step up and really help the team.?
Filling those holes has been the first priority for Cochrane during the preseason, starting with the infield.
Amir Alzer, Nick Gutierrez, Nathan Harwell and Michael Dayanandan are all expected to see expanded playing time in the infield this spring, while senior Jackson Paine will take over the duties behind the plate.
Paine will be calling the signals for one of the best starting pitching duos in Central Texas. Reigning District 25-4A MVP, and future Vanderbilt Commodore, Ryan Johnson posted a 6-0 record while striking out 60 and only allowing 10 earned runs in 62.1 innings of work. Tanner Dickerson, who signed with University of Texas-Pan American, posted a 1.69 ERA and struck out 52 in nine starts.
Dickerson will have a big role on offense, too.
?We have our first three set and Taylor will bat third, but after that we are figuring things out and plugging different guys in,? Cochrane said.
LEANDER: Lions ready for traditional rivalries with senior-loaded roster
Traditional rivalries are back for the Leander High School baseball team and, with a veteran roster, the Lions are ready to compete for a playoff spot in District 25-4A.
Leander spent the past two seasons in District 16-5A grouped with Round Rock and Pflugerville school district teams. This season the Lions move down from 5A to 4A and back into familiar territory with their four Leander school district rivals.
?I?m looking forward to it,? Leander coach Matt Grissom said. ?We were in a good 5A district, but this is such a good baseball area and we?re moving into a very talented 4A district, where we know all of the teams. It?ll be exciting for the kids to finally be able to play the kids they grew up with in CPYL and those rivalries will be exciting to watch play out again.?
Last season Leander went 6-12 in District 16-5A and finished three games out of a playoff spot. This season the Lions are contenders for one of District 25-4A?s four playoff spots with a roster loaded with seniors ? 17 of them.
?I really enjoy being around this group, we?ve got a lot of guys who have that varsity experience and want to win,? Grissom said. ?I?m just excited to be able to have so many guys that care and love to play baseball in this program.?
The Lions do have some holes to fill. They graduated seven seniors last season, but that competition to fill those roles has been a learning tool Grissom has used to prepare for the season.
ROUSE: Raiders hoping to take overall athletic success on to the diamond
As a whole the Rouse athletic program has taken giant strides this season, finally evening the playing field and taking advantage of experienced athletes who have played varsity sports since they were freshmen or sophomores.
Rouse baseball coach Paul Cochrane plans to follow that same blueprint this season.
?We?ve got a lot of experience, especially since most of the guys are now seniors who helped open the school,? Cochrane said.
Last season Rouse missed the playoffs by one game, losing to Marble Falls in a head-to-head battle for the final playoff spot after going 4-8 in District 25-4A. This season the Raiders have goals of reaching the playoffs and with 10 seniors return most of the core group from last season.
Unfortunately for the Raiders, they?ll be without University of Texas at San Antonio-bound pitcher and outfielder Logan Kinder, who will miss the entire season with an injury. Kinder had a 2.43 ERA and struck out 57 on the mound and batted .357.
?That?s a big hit,? Cochrane said. ?You can?t go and replace a guy like Logan, but some of the other guys are stepping up and we are starting to see the full team come together during our past couple of scrimmages.?
VANDEGRIFT: Vipers ready to take next step as a program
One game was all that separated the Vandegrift baseball team from reaching the playoffs last season.
The Vipers finished in a three-way tie for third place in District 25-4A with Rouse and Marble Falls, with the Mustangs ultimately reaching the postseason after winning the head-to-head battles.
This season Vandegrift is ?heads and shoulders? ahead of where it was the previous three seasons, and coach Christopher Seaman expects his team to turn the corner and make the playoffs.
?Our guys have been working hard and are way ahead of where they were the past three years,? Seaman said. ?We have seven guys who are four-year lettermen and we have that maturity and the fight you really want to see out of team. When you start a new program you hear it takes six years to really get there. Well, this is year four and I think we are right where we need to be.?
Vandegrift showed flashes of that last season after winning one-run games against playoff-bound teams Lake Travis and Vista Ridge, but still felt the growing pains and finished 8-18 overall and 4-8 in district play.
?We were one game from making the playoffs last season, I don?t think that?s something people realize when they look at our record,? Seaman said. ?The kids have a taste of being that close now, it?s really the time for them to take it.?
VISTA RIDGE: Rangers hoping to compete for district title
The Vista Ridge baseball team spent the preseason working out the kinks and filling in some of the holes left be graduation.
Now, it?s time for the Rangers to focus one task, playing solid baseball.
?We graduated several key players and we have some people filling in and taking those roles,? Vista Ridge coach Jason Bourgeois said. ?But, that?s starting to figure itself out and now we are just getting the kids to play good baseball every day.?
And if Vista Ridge can play ?good baseball? for the rest of the season the Rangers could be competing for the District 25-4A title.
Vista Ridge went 17-14 last season and 7-5 in District 25-4A, and return reigning offensive MVP Dylan Bein who has committed to play college baseball at Texas State.? Bein will also be the cornerstone of the Rangers? pitching staff which will include Alek Lando, Brett Burrington and Tyler Ziemann.
?We?ve got a pretty reliable pitching staff and some guys who have the experience you need to go out and win games,? Bourgeois said. ?Now we?ve been just nailing down fundamentals on offense and defense during scrimmages, and we?re pretty close to being the team we need to be.?

NCAA says three former Miami assistants misled investigators
CORAL GABLES, Fla. -- The NCAA believes former Miami assistant coaches Clint Hurtt, Aubrey Hill and Jorge Fernandez provided false or misleading information during the probe into the Hurricanes' athletic department.
The NCAA said all three violated "principles of ethical conduct" as part of the notice of allegations served against the Hurricanes, according to a person who spoke to the Associated Press on Wednesday on condition of anonymity because the allegations have not been released publicly.
Hurtt and Hill were members of Miami's football staff. Fernandez worked on the men's basketball staff.
Several other coaches are named or referenced in the allegations, including Missouri basketball coach Frank Haith. But only Hurtt, Hill and Fernandez are facing the ethical-conduct charge, commonly known as NCAA Rule 10.1.
Hurtt is currently on the staff at Louisville. Hill is not working as a coach at this time, and Fernandez spent last season as an assistant at Marshall, resigning last May.
The notice of allegations was delivered to Miami on Tuesday, and the university is facing the charge that it had a "lack of institutional control" -- one of the worst things the NCAA can levy against a member school. The charge revolves around how the school allegedly failed to monitor conduct of Nevin Shapiro, a rogue booster and convicted felon who provided cash, gifts and other items to players on the football and men's basketball teams.
University president Donna Shalala said Tuesday night that the Hurricanes have suffered enough already through self-imposed sanctions. Through a university spokesman, she declined further comment Wednesday.
The NCAA said Hurtt and Hill committed the same violations, at least related to the ethical-conduct matter.
The NCAA alleged both provided meals, transportation and lodging to either recruits, current players or both in either 2008 or 2009. Both were interviewed by the NCAA during the course of its probe and allegedly denied providing those extra benefits, statements the NCAA said were contradicted in each case by what players told them separately.
Hurtt also took a $2,500 personal loan from Shapiro, which was repaid. The NCAA also believes he sent about 40 impermissible text messages to recruits, which typically is a secondary, or minor, violation.
Fernandez, the NCAA alleged, "knowingly provided extra benefits" in the form of an air ticket. The NCAA said Fernandez denied using air miles for the tickets for a men's basketball player and a high school coach, despite evidence to the contrary.
In February 2012, Miami center Reggie Johnson was ruled ineligible by the school after an investigation revealed that members of his family accepted "impermissible travel benefits" from a member of the school's former coaching staff, without specifying Fernandez or anyone else by name. The university said Johnson was not aware of the benefits, personally accepted nothing and that his family had been told they were allowed.
Johnson was reinstated quickly last season, and remains a key part of this season's team -- now ranked No. 2 in the nation and leading the Atlantic Coast Conference. The ongoing cloud of the scandal is not hurting the Hurricanes, basketball coach Jim Larranaga said Tuesday night.
"If it was overshadowing what we were doing, this room would not be packed," Larranaga said after his team beat Virginia. "We're getting so much exposure. We can only focus on the things we have control over. We have nothing to do with the investigation."
Several other former Miami coaches are named in the allegations as well, including one-time men's basketball assistant Jake Morton, who the NCAA said, among other things, accepted "supplemental income" of at least $6,000 from Shapiro. Morton is now on the staff at Western Kentucky.
Missouri's Haith is accused of failing "to promote an atmosphere for compliance," a charge specific to how he handled things when Shapiro allegedly wanted money in exchange for not going public with accusations that he paid to help the Hurricanes recruit a player.
Some of the allegations are more than 10 years old, including a claim that Shapiro bought a suit for former Miami star running back Willis McGahee to wear to the Heisman Trophy ceremony in 2002.
Other allegations include that he paid for dinners at Benihana, televisions, sneakers, Miami Heat tickets, bowling parties, one player's engagement ring, a used washer-dryer set for current New England Patriots lineman Vince Wilfork, and that he directed his girlfriend to give two former Hurricanes no-show jobs for a couple of months.

How to Curb Your Clutter (and Reduce Stress In the Process)
Does this sound familiar? You're on your way out the door and can't find your keys. Looking around, you find stacks of junk mail, magazines, clothes you've worn once but are not ready to wash. After 15 minutes of searching, you're late for that lunch appointment. Now imagine this. You're up late finishing a presentation, and you're really struggling. You look at your computer desktop and it's a total mess. You feel like you're not in control.
Letting physical or digital things pile up can cause you a lot of stress.
Critical Mass of Clutter
Here's what I think happens. When you reach a certain level of clutter, you start experiencing significantly more stress. This is how I imagine it:
The amount of clutter at some arbitrary point A is the "critical mass of clutter." At this level of messiness, you to start losing bills or feel like you can't quickly clean up when it becomes distracting to the work at hand. In other words, going from pristine to a causes you some stress level of C, but getting to the slightly messier B suddenly doubles the stress to D.
Even without catalysts like the need to find something or an imposing work deadline, this heightened level of clutter also makes life less enjoyable. You start to decide against inviting friends over after a nice dinner out. You can't lounge in your favorite chair because it's now a receptacle for miscellany. You don't have enough room on your desk to draw.
Worse, clutter also creates a negative feedback loop that makes you susceptible to creating an even bigger mess. Economists who study littering have some interesting insights here. In one paper, two economists create a model that argues that those living in environments with lots of litter don't mind leaving a piece of litter because it only makes their surroundings a little bit worse (Anderson and Francois 1997). A more recent paper (Dur and Vollaard 2012) reviews numerous studies done on littering and concludes that:
With a few exceptions, these experimental studies find that people litter significantly more often in littered environments as compared to clean environments.
In sum: Critical mass of clutter feeds stress events, reduces quality of life, and creates negative loop of mess creation.
A Proposal: Maintenance Mondays
One of the challenging things about being at a startup (and other high velocity environments) is that there's always something to do in the never-ending lists of next actions. This means that maintenance tasks like improving performance or keeping our shared Dropbox folder organized are never a particularly urgent or important at any given moment?until something bad happens.
We recently started doing Maintenance Mondays at Astrid, inspired by our co-founder Tim's themed days. On maintenance days, our engineers work on addressing our tech debt, performance, bug fixes, and polish. Performance issues can be ignored in the short run, but piled up they can suddenly crash the website. Designating a day to address "maintenance" has been a good model for my personal life too. I've been using Maintenance Mondays to clear out my desktop and tidy up my room.
One Step Further: the One-Minute Rule
I also recently adopted the One-Minute Rule, which makes maintenance days easier. The rule is simple: if something takes a minute or less to complete, do it now. That means hanging up the coat when you take it off and filing a receipt you pull out of your pocket.
The trick is to create rules that take decision-making out of keeping your life in control. If it's 3pm on Monday, it's maintenance time. If putting away this box of cereal takes less than a minute, in the pantry it goes.

Jury orders Dow Chemical to pay $400 million in price-fixing case
(Reuters) - A federal jury has ordered Dow Chemical Co
Dow was one of several chemical company defendants named in a class action lawsuit alleging a conspiracy to fix urethane chemical prices, but it was the only defendant not to settle.
Last month, it went to trial in a federal court in Kansas City.
The plaintiffs, purchasers of urethane chemicals, had sought more than $1 billion in damages from Dow.
If the $400 million verdict is approved by the judge overseeing the case, it could be tripled under federal antitrust law.
David Bernick, an attorney for Dow, said that the company would seek to dismiss the lawsuit in a post-trial motion.
Separately, Dow said in a statement late on Wednesday that it was disappointed the jury found price fixing conduct during part of the time frame at issue, and that it continues to deny those allegations.
The plaintiffs had sought damages for a five-year conspiracy, but the jury did not find Dow liable for the full five years, he said.
"We think it's very clear that the jury rejected the five-year class conspiracy claim and there was no other claim," Bernick said.
Joe Goldberg, an attorney for the plaintiffs, said he was pleased with the verdict.
"The people of Kansas administered justice, consistent with the evidence," Goldberg said.
Other defendants in the case have settled. In 2006 Bayer AG agreed to pay $55 million. In 2011 Huntsman International LLC agreed to pay $33 million and BASF Corp agreed to pay $51 million. In settling, none of the companies admitted any wrongdoing.
The case is In Re Urethane Antitrust Litigation, U.S. District Court, District of Kansas, 04-md-01616.

New technique scales up production of graphene micro-supercapacitors
Feb. 19, 2013 ? While the demand for ever-smaller electronic devices has spurred the miniaturization of a variety of technologies, one area has lagged behind in this downsizing revolution: energy-storage units, such as batteries and capacitors.
Now, Richard Kaner, a member of the California NanoSystems Institute at UCLA and a professor of chemistry and biochemistry, and Maher El-Kady, a graduate student in Kaner's laboratory, may have changed the game.
The UCLA researchers have developed a groundbreaking technique that uses a DVD burner to fabricate micro-scale graphene-based supercapacitors -- devices that can charge and discharge a hundred to a thousand times faster than standard batteries. These micro-supercapacitors, made from a one-atom-thick layer of graphitic carbon, can be easily manufactured and readily integrated into small devices such as next-generation pacemakers.
The new cost-effective fabrication method, described in a study published this week in the journal Nature Communications, holds promise for the mass production of these supercapacitors, which have the potential to transform electronics and other fields.
"The integration of energy-storage units with electronic circuits is challenging and often limits the miniaturization of the entire system," said Kaner, who is also a professor of materials science and engineering at UCLA's Henry Samueli School of Engineering and Applied Science. "This is because the necessary energy-storage components scale down poorly in size and are not well suited to the planar geometries of most integrated fabrication processes."
"Traditional methods for the fabrication of micro-supercapacitors involve labor-intensive lithographic techniques that have proven difficult for building cost-effective devices, thus limiting their commercial application," El-Kady said. "Instead, we used a consumer-grade LightScribe DVD burner to produce graphene micro-supercapacitors over large areas at a fraction of the cost of traditional devices. Using this technique, we have been able to produce more than 100 micro-supercapacitors on a single disc in less than 30 minutes, using inexpensive materials."
The process of miniaturization often relies on flattening technology, making devices thinner and more like a geometric plane that has only two dimensions. In developing their new micro-supercapacitor, Kaner and El-Kady used a two-dimensional sheet of carbon, known as graphene, which only has the thickness of a single atom in the third dimension.
Kaner and El-Kady took advantage of a new structural design during the fabrication. For any supercapacitor to be effective, two separated electrodes have to be positioned so that the available surface area between them is maximized. This allows the supercapacitor to store a greater charge. A previous design stacked the layers of graphene serving as electrodes, like the slices of bread on a sandwich. While this design was functional, however, it was not compatible with integrated circuits.
In their new design, the researchers placed the electrodes side by side using an interdigitated pattern, akin to interwoven fingers. This helped to maximize the accessible surface area available for each of the two electrodes while also reducing the path over which ions in the electrolyte would need to diffuse. As a result, the new supercapacitors have more charge capacity and rate capability than their stacked counterparts.
Interestingly, the researchers found that by placing more electrodes per unit area, they boosted the micro-supercapacitor's ability to store even more charge.
Kaner and El-Kady were able to fabricate these intricate supercapacitors using an affordable and scalable technique that they had developed earlier. They glued a layer of plastic onto the surface of a DVD and then coated the plastic with a layer of graphite oxide. Then, they simply inserted the coated disc into a commercially available LightScribe optical drive -- traditionally used to label DVDs -- and took advantage of the drive's own laser to create the interdigitated pattern. The laser scribing is so precise that none of the "interwoven fingers" touch each other, which would short-circuit the supercapacitor.
"To label discs using LightScribe, the surface of the disc is coated with a reactive dye that changes color on exposure to the laser light. Instead of printing on this specialized coating, our approach is to coat the disc with a film of graphite oxide, which then can be directly printed on," Kaner said. "We previously found an unusual photo-thermal effect in which graphite oxide absorbs the laser light and is converted into graphene in a similar fashion to the commercial LightScribe process. With the precision of the laser, the drive renders the computer-designed pattern onto the graphite oxide film to produce the desired graphene circuits."
"The process is straightforward, cost-effective and can be done at home," El-Kady said. "One only needs a DVD burner and graphite oxide dispersion in water, which is commercially available at a moderate cost."
The new micro-supercapacitors are also highly bendable and twistable, making them potentially useful as energy-storage devices in flexible electronics like roll-up displays and TVs, e-paper, and even wearable electronics.
The researchers showed the utility of their new laser-scribed graphene micro-supercapacitor in an all-solid form, which would enable any new device incorporating them to be more easily shaped and flexible. The micro-supercapacitors can also be fabricated directly on a chip using the same technique, making them highly useful for integration into micro-electromechanical systems (MEMS) or complementary metal-oxide-semiconductors (CMOS).
These micro-supercapacitors show excellent cycling stability, an important advantage over micro-batteries, which have shorter lifespans and which could pose a major problem when embedded in permanent structures -- such as biomedical implants, active radio-frequency identification tags and embedded micro-sensors -- for which no maintenance or replacement is possible.
As they can be directly integrated on-chip, these micro-supercapacitors may help to better extract energy from solar, mechanical and thermal sources and thus make more efficient self-powered systems. They could also be fabricated on the backside of solar cells in both portable devices and rooftop installations to store power generated during the day for use after sundown, helping to provide electricity around the clock when connection to the grid is not possible.
"We are now looking for industry partners to help us mass-produce our graphene micro-supercapacitors," Kaner said.

Armoires Travel From Ancient Rome to High-Style Storage (6 photos)
Freestanding armoires. Freestanding armoires, with single or double doors and enclosed drawers, were also popular in the 14th century. These easily transported storage solutions were usually considered the property of the landowner, although there is evidence that some were the personal property of the home owner.
Medieval armoires were constructed to be functional, practical pieces of furniture. Sometimes medieval armoires had paint or gilding on them, but not often.
This armoire is a simple refined design that links the table and the mantel together, grounding the room and giving it structure.

Worker ignores doctor's orders: Can we discipline? ? Business ...
Q. One of our employees who is out on workers? comp isn?t following the treatment prescribed by the workers? comp doctor. She fails to attend physical therapy as prescribed. She says she?s still in pain and can?t return. Our conduct policy sets progressive discipline based on different offenses. Can the failure to abide by the doctor?s orders be included as a violation? ? Sallie, Pennsylvania
A. Disciplining employees with medical issues is always complicated. As an initial matter, an employer cannot retaliate against an employee for filing a workers? compensation claim, so I would avoid putting ?workers? compensation? and ?rules of conduct? in the same category. In some cases, a worker?s failure to comply with the physician?s in??structions may not constitute misconduct, particularly if the employee believes the physician has made an error.
However, concerns about retaliation or disability discrimination don?t mean you must continue to employ someone whose condition does not improve. If the employee doesn?t seem to be improving, work with your workers? comp insurer to see if the employee has reached maximum medical improvement or is, in fact, failing to comply with instructions. Even if the employee is complying, if he can?t perform the essential functions of the job after rehabilitation, you may have the right to reassign him or even terminate him.
I suggest you keep your conduct policy flexible, because you can?t possibly list every type of conduct that might lead to discipline, and moreover keep medical issues out of it. For this worker, consult with a local attorney regarding your obligation to accommodate his slow recovery.

Explosives vapor detection technology: The new 'sniff test'
Feb. 20, 2013 ? A quick, accurate and highly sensitive process to reliably detect minute traces of explosives on luggage, cargo or travelling passengers has been demonstrated by scientists at the Department of Energy's Pacific Northwest National Laboratory. The vapor detection technology accurately detects and identifies the vapors of even very low-volatility explosives in real time at ambient temperature and without sample pre-concentration. Details are outlined in a recent issue of Analytical Chemistry.
Rather than searching for particle residue using a typical method like surface swipes or using pulses of air to dislodge particles for analysis, the system 'sniffs' directly for explosives vapors, much the way bomb-sniffing canines do.
"We have demonstrated direct, real-time vapor detection for the low-volatility explosive compound RDX, which is used in many types of explosives," said David Atkinson, senior research scientist at PNNL. Low-volatility compounds are those which release very small amounts of the explosive vapor typically at parts per trillion levels or lower, making it extremely difficult to detect. The PNNL system easily detects vapors from a fingerprint-sized sample of RDX at levels below 25 parts per quadrillion.
"The system correctly identified the RDX vapor using selective atmospheric pressure chemical ionization with mass spectrometry," explained Atkinson. The approach involves pulling an air sample stream and ionizing it within a reaction region in an atmospheric flow tube. The ionized sample moves to a mass spectrometer for ion detection and identification. These air samples need no heating or pre-concentrating. Analysis happens in about one second.
"The key part is ionization," said Atkinson. "We tailored the chemistry to greatly enhance both ionization efficiency and selectivity, which results in the best possible detection."
Only a limited number of ultra-sensitive detection methods have been found capable of detecting low-volatility explosive compounds at levels below parts-per-trillion. But these methods typically take much longer and require pre-concentration of the sample from the vapor phase.
Currently, most airport security agents use cloth-like material to swipe luggage and cargo to collect explosives particles for detection. The samples are then analyzed one at a time in a process that requires the swipe to be heated to a temperature needed to volatilize the particles for detection.
In some cases, airport security will turn to canines for detection, especially for large items where size such as vehicles or cargo make particle sampling impractical.
"What we are attempting to develop is an instrument that replicates or surpasses the capabilities of a dog," said Atkinson. However, while canine olfactory systems are highly developed, dogs present issues that machines don't. Man's best friend only works limited hours, must be fed, exercised regularly and rested. While a dog's ability to smell and detect explosives is extremely sensitive, instruments may soon surpass their capabilities and perform at a lower cost.
Robert Ewing, PNNL senior research scientist, sees a bright future for the technology and is hoping to push the performance even further.
"Currently we have demonstrated the detection of explosive compounds such as RDX, PETN, nitroglycerine and tetryl, along with plastic explosives that contain these materials at low parts per quadrillion levels," said Ewing. "Future research will focus on detecting other explosive threats by manipulating the ionization chemistry and lowering detection limits."
