Qigong Improves Quality of Life for Breast Cancer Patients | Psych ...
Reviewed by John M. Grohol, Psy.D. on January 27, 2013
The study examined qigong in patients receiving radiation therapy and included a follow-up period to assess its benefits over time, according to researchers.
?We were [...] particularly interested to see if qigong would benefit patients experiencing depressive symptoms at the start of treatment,? said Lorenzo Cohen, Ph.D., a professor in the University of Texas M. D. Anderson Cancer Center?s Departments of General Oncology and Behavioral Science.
?It is important for cancer patients to manage stress because it can have a profoundly negative effect on biological systems and inflammatory profiles.?
For the study, Cohen and his colleagues recruited 96 women with stage 1-3 breast cancer from Fudan University Shanghai Cancer Center in Shanghai, China.
About half of the women ? 49 ? were randomly assigned to a qigong group consisting of five 40-minute classes each week during their five-to-six week course of radiation therapy. The remaining 47 women comprised a control group receiving standard care.
The program incorporated a modified version of Chinese medical qigong, which consisted of synchronizing one?s breath with various exercises, the researchers explained.
Participants in both groups completed assessments at the beginning, middle and end of radiation therapy and then one and three months later. Different aspects of quality of life were measured, including depressive symptoms, fatigue, sleep disturbances, and overall quality of life.
According to the researchers, patients in the qigong group reported a steady decline in depressive symptom scores beginning at the end of radiation therapy, with a mean score of 12.3, through the three month post-radiation follow-up with a score of 9.5. No changes were noted in the control group over time, the study found.
The study also found that qigong was especially helpful for women reporting high baseline depressive symptoms, Cohen said.
?We examined women?s depressive symptoms at the start of the study to see if women with higher levels would benefit more,? he said.
?In fact, women with low levels of depressive symptoms at the start of radiotherapy had good quality of life throughout treatment and three months later regardless of whether they were in the qigong or control group. However, women with high depressive symptoms in the control group reported the worst levels of depressive symptoms, fatigue, and overall quality of life that were significantly improved for the women in the qigong group.?
As the benefits of qigong were largely observed after treatment concluded, researchers suggest qigong may prevent a delayed symptom burden or expedite the recovery process, especially for women with elevated depressive symptoms at the start of radiation therapy. Cohen notes the delayed effect could be explained by the cumulative nature of the treatments, as the benefits often take time to be realized.
According to the researchers, the findings support other previously reported trials examining the benefits of qigong, but are too preliminary to offer clinical recommendations.
They note that additional research is needed to understand the possible biological mechanisms involved and further explore the use of qigong in ethnically diverse populations with different forms of cancer.
The study was published in the journal Cancer.

Bioinspired fibers change color when stretched
Jan. 28, 2013 ? A team of materials scientists at Harvard University and the University of Exeter, UK, have invented a new fiber that changes color when stretched. Inspired by nature, the researchers identified and replicated the unique structural elements that create the bright iridescent blue color of a tropical plant's fruit.
The multilayered fiber, described January 28 in the journal Advanced Materials, could lend itself to the creation of smart fabrics that visibly react to heat or pressure.
"Our new fiber is based on a structure we found in nature, and through clever engineering we've taken its capabilities a step further," says lead author Mathias Kolle, a postdoctoral fellow at the Harvard School of Engineering and Applied Sciences (SEAS). "The plant, of course, cannot change color. By combining its structure with an elastic material, however, we've created an artificial version that passes through a full rainbow of colors as it's stretched."
Since the evolution of the first eye on Earth more than 500 million years ago, the success of many organisms has relied upon the way they interact with light and color, making them useful models for the creation of new materials. For seeds and fruit in particular, bright color is thought to have evolved to attract the agents of seed dispersal, especially birds.
The fruit of the South American tropical plant, Margaritaria nobilis, commonly called "bastard hogberry," is an intriguing example of this adaptation. The ultra-bright blue fruit, which is low in nutritious content, mimics a more fleshy and nutritious competitor. Deceived birds eat the fruit and ultimately release its seeds over a wide geographic area.
"The fruit of this bastard hogberry plant was scientifically delightful to pick," says principal investigator Peter Vukusic, Associate Professor in Natural Photonics at the University of Exeter. "The light-manipulating architecture its surface layer presents, which has evolved to serve a specific biological function, has inspired an extremely useful and interesting technological design."
Vukusic and his collaborators at Harvard studied the structural origin of the seed's vibrant color. They discovered that the upper cells in the seed's skin contain a curved, repeating pattern, which creates color through the interference of light waves. (A similar mechanism is responsible for the bright colors of soap bubbles.) The team's analysis revealed that multiple layers of cells in the seed coat are each made up of a cylindrically layered architecture with high regularity on the nano- scale.
The team replicated the key structural elements of the fruit to create flexible, stretchable and color-changing photonic fibers using an innovative roll-up mechanism perfected in the Harvard laboratories.
"For our artificial structure, we cut down the complexity of the fruit to just its key elements," explains Kolle. "We use very thin fibers and wrap a polymer bilayer around them. That gives us the refractive index contrast, the right number of layers, and the curved, cylindrical cross-section that we need to produce these vivid colors."
The researchers say that the process could be scaled up and developed to suit industrial production.
"Our fiber-rolling technique allows the use of a wide range of materials, especially elastic ones, with the color-tuning range exceeding by an order of magnitude anything that has been reported for thermally drawn fibers," says coauthor Joanna Aizenberg, Amy Smith Berylson Professor of Materials Science at Harvard SEAS, and Kolle's adviser. Aizenberg is also Director of the Kavli Institute for Bionano Science and Technology at Harvard and a Core Faculty Member at the Wyss Institute for Biologically Inspired Engineering at Harvard.
The fibers' superior mechanical properties, combined with their demonstrated color brilliance and tunability, make them very versatile. For instance, the fibers can be wound to coat complex shapes. Because the fibers change color under strain, the technology could lend itself to smart sports textiles that change color in areas of muscle tension, or that sense when an object is placed under strain as a result of heat.
Additional coauthors included Alfred Lethbridge at the University of Exeter, Moritz Kreysing at Ludwig Maximilians University (Germany), and Jeremy B. Baumberg, Professor of Nanophotonics at the University of Cambridge (UK).
This research was supported by the U.S. Air Force Office of Scientific Research Multidisciplinary University Research Initiative, by the UK Engineering and Physical Sciences Research Council, and through a postdoctoral research fellowship from the Alexander von Humboldt Foundation. The researchers also benefited from facilities at the Harvard Center for Nanoscale Systems, which is part of the National Nanotechnology Infrastructure Network supported by the U.S. National Science Foundation. The Wyss Institute for Biologically Inspired Engineering at Harvard also contributed to this research.

German lawmakers give Cameron qualified backing on EU
BERLIN (Reuters) - Britain is right to demand greater openness in the European Union but cannot expect to be accorded special rights that might unravel the bloc, senior members of German Chancellor Angela Merkel's coalition were quoted on Sunday as saying.
British Prime Minister David Cameron triggered dismay in many European capitals last week with his call for radical reform of the EU and his promise of an "in-out" referendum on Britain's membership by the end of 2017, provided he wins a second term.
Germany, Europe's largest economy, is keen to keep a kindred advocate of free trade and open markets inside the EU and has been more measured in its criticism while making clear there are limits to how far it can go in accommodating British concerns.
"It would be entirely wrong to respond to Prime Minister Cameron's overture with a kneejerk rejection," said Alexander Dobrindt, general secretary of the Christian Social Union (CSU), Bavarian sister party of Merkel's Christian Democrats (CDU).
"Whoever condemns wholesale Cameron's idea for a national referendum on Europe fans distrust towards Europe, as if Europe must hide away from people," he told weekly Spiegel magazine.
Bavaria's Economy Minister Martin Zeil, of the liberal Free Democrats (FDP), junior partner in Merkel's coalition, also defended Cameron's speech, especially his call for measures to improve Europe's competitiveness.
Both the CSU and the FDP have become more critical of the European Union during the euro zone debt crisis amid concerns the currency area may turn into a 'transfer union' whereby richer countries such as Germany have to keep bailing out poorer neighbours.
But Dobrindt also signalled the limits of German patience.
"It is clear that in an optimal Europe there can be no place for special rights for individual countries," he said, adding that included Britain's cherished rebate negotiated in the 1980s that reduces its contribution to the EU's central budget.
German Foreign Minister Guido Westerwelle of the FDP said in an article for Die Welt newspaper there could be no far-reaching repatriation of EU competences to the national level as Cameron wants because it would wreck the single market.
"I fear that in so doing we would call up spirits which, like the sorcerer's apprentice in Goethe's poem, we would no longer be able to control," he wrote in an article which also endorsed British calls for more transparency in the EU.
Merkel, speaking in Chile during a summit of European and Latin American leaders, repeated her view that London and its European partners must seek a mutually acceptable compromise.
Merkel said she told Latin American leaders quizzing her about a possible British exit: "We, insofar as we represent here the whole EU, say quite unanimously that we wish Britain to stay in the EU."

PHILADELPHIA (AP) ? Ryan Arcidiacono hit the tying 3-pointer with 2.2 seconds left in regulation, and James Bell hit consecutive 3s in overtime to send Villanova to its second win over a Top 5 team this week, 75-71 over No. 3 Syracuse on Saturday.
The Wildcats defeated No. 5 Louisville 73-64 on Tuesday and became the first unranked team to beat two Top 5 teams in the same season since Florida State in 2011-12, according to STATS LLC.
Arcidiacono's 3-point attempt to tie with about 25 seconds left in regulation was off the mark. Syracuse's Michael Carter-Williams missed the front end of a 1-and-1 and JayVaughn Pinkston of the Wildcats grabbed the rebound.
Bell missed a 3 and Mouphtaou Yarou grabbed the offensive rebound. Syracuse decided not to foul, giving Yarou time to kick it out to Arcidiacono. He let go a leaner from just beyond the 3-point line to tie the game at 61, force overtime and send the crowd into a frenzy.
With the Orange (18-2, 6-1 Big East) down two points in overtime, Brandon Triche made one free throw with 46.5 seconds left.
Bell followed with a layup to for a 71-68 lead and the Wildcats (13-7, 4-3) held on from the free throw line.
Philly's college fans came down with a case of court-storming fever this week after Villanova's win over Louisville and La Salle's 54-53 win the next night over No. 9 Butler. At the Wells Fargo Center, home of the NHL's Flyers, the fans made it a Philly hoops hat trick, rushing the court in celebration of one of the biggest regular-season weeks in Villanova history.
Florida State beat No.3 North Carolina and No. 4 Duke in its big week.
Darrun Hilliard scored 25 points and Yarou had 14 points and 16 rebounds for the Wildcats while Bell scored 13 points.
Triche led the Orange with 23 points and Carter-Williams scored 17 points. The Orange had an eight-game winning streak and both of their losses came to Philadelphia teams. They lost to Temple on Dec. 22.
The Orange clearly could have use James Southerland in the tight game. Southerland, second on the team in scoring at 13.6 points and the team leader with 33 3-pointers, was declared out indefinitely because of an eligibility matter involving academics that has yet to be resolved.
Jerami Grant, who played well in Southerland's absence, fouled out with 5:22 left and the Orange up one. His fifth foul was against Hilliard. Hilliard missed both from the line, the Orange stormed down in transition off the defensive board, and Triche hit a 3 for a 57-53 lead.
The Orange just could never put them away. They missed six of eight shots in overtime and were only 5 of 14 overall from 3-point range.
Grant's 3-pointer early in the second half gave the Orange their first lead of the game, 33-32.
The Wildcats gave all the students standing behind each basket and dressed in white an early reason to think they would be rushing again. They opened the game on a 10-0 run and stretched the lead to 25-13. But the fun didn't last long.
Triche, a 50 percent shooter on the season, hit Syracuse's first 3-pointer of the half to slice the lead to four. He tipped in a basket at the buzzer to cut the lead to 32-26.
Syracuse missed 10 of its first 14 shots and finished at 29 percent for the half.

Fragile economy, other global woes dominated Davos

DAVOS, Switzerland (AP) ? The fragile state of the world economy, along with the relentless turmoil in Syria and the rocky fallout from the Arab Spring, dominated discussions during this year's annual gathering of the global elite at Davos, leaving many participants uneasy about what lies ahead as they left for home Sunday.
Even broad agreement that there are some positive signs on the economic front, at least in emerging markets, was coupled with a warning from the head of the International Monetary Fund. "Do not relax," Christine Lagarde said. There's still a "risk of relapse."
More than 2,500 of the best and brightest in business, government, academia and civic life gathered for the five-day World Economic Forum at this Alpine resort. But much of the overt glitz and glamor that is a usual feature was toned down or absent this year, a decision founder Klaus Schwab said reflected the serious issues facing the world.
Political and economic issues vie for top billing each year at Davos, and this time, the economy had the edge, with a special focus on how to promote economic growth and jobs, especially for the youth among the world's 220 million jobless.
The IMF said that China, Africa, and other emerging markets could see significant growth, but Japan, eurozone nations and the U.S. are likely to struggle with negative to low growth. Ahead of the 43rd forum, the IMF downgraded its forecast for global economic growth this year by one-tenth of a percentage point to 3.5 percent.
While the U.S. avoided the so-called "fiscal cliff" of automatic tax increases and spending cuts, and fears have abated that the euro currency union will break up, there is growing concern that governments may ease up on measures to improve growth and reduce debt that the IMF and many other institutions are calling for.
IMF chief Lagarde said the "very fragile and timid recovery" depends on leaders in the 17-nation eurozone, the United States and Japan making "the right decisions." The eurozone in particular "is fragile because it is prone to political crisis" and slow decision-making, she said.
Davos participants' uneasiness about the world economy was matched by growing concern over the political turmoil in the Arab world, terrorism in North Africa, a spate of natural disasters that have highlighted the failure to tackle climate change, and the growing inequality between the world's "haves" and "have nots."
"Two years ago, gloom around the stalled economic recovery was leavened by euphoria at the outbreak of the Arab spring," Kenneth Roth, the executive director of Human Rights Watch, told The Associated Press at Saturday night's low-key final reception. "This year, relief at the improved economic outlook is tempered by despair at the unimpeded slaughter in Syria, uncertainty about the outlook in Egypt, and frustration over the Arab monarchies' resistance to reform."
The Arab Spring uprisings have ousted dictators in Tunisia, Yemen, Libya and Egypt over the past two years. But now Islamists and liberals are wrangling over power, with Islamists mainly gaining the upper hand. Democracy is far from certain, and economic woes have left hundreds of thousands of young people jobless and frustrated that their "revolutions" haven't produced any dividends.
Former Arab League Secretary-General Amr Moussa, a losing candidate in Egypt's presidential election last year, said there have been achievements, but warned that democracy isn't only about casting a vote.
"It is the respect of human rights, for rights of women, separation of powers, independence of the judiciary. This meaning of democracy we have not yet achieved," Moussa said.
Elsewhere in the Middle East, Israeli-Palestinian peace talks remain stalled, Arab monarchs remain entrenched, and the death toll from the escalating civil war in Syria has topped 60,000 with no end in sight.
Jordan's King Abdullah II, whose country is hosting almost 300,000 Syrian refugees, predicted that Syrian President Bashar Assad's regime will last at least another six months. He called for a transition plan involving all Syrians and the Syrian army.
He also urged stepped up international support to end the Syrian crisis, saying, "The weakest refugees are struggling now just to survive this year's harsh winter."
Abdullah told the forum that "unprecedented threats to regional and global stability and security" need international action now, not the "wait and see" response by some countries ? which he did not identify ? especially in helping governments emerge politically and financially from the Arab uprisings.
The king, considered one of the region's moderate leaders, also warned Israel to stop playing the "waiting game," and said President Barack Obama's second term offered the last opportunity to create two states ? Palestine and Israel ? that can live side-by-side in peace.
Angel Gurria, secretary-general of the Paris-based Organization for Economic Cooperation and Development, said the focus on resolving the world's economic crisis has distracted leaders from many other important issues, including education, the social consequences of unemployment and promoting ways to deal with climate change.
Nonetheless, Gurria said, the world should be "very worried" because there aren't many "tools" left to fix the economy if things get worse.
Trevor Manuel, South Africa's National Planning Commission minister, told AP that the key message from Davos for him was a positive one ? that "many of the decisions that have been taken bring us closer to where we need to be." He warned that "a sense of an all-pervasive gloom ... frequently becomes a self-fulfilling prophecy."

Imagining a skeuomorphic-free, all-aluminium iOS 7
Skeuomorphism -- the use of real world design in a digital context -- has been a target lately. At the extreme, it's held up as an example of iOS being boring, outdated, and bereft of innovation. In more reasonably terms, it's looked at as something that can be useful, but has perhaps been overused. I've gone on record as saying I think there are far more important things Apple needs to do in iOS 7 than wiping the world clean of skeuomorphism, both here on the site and in a podcast rant. But let's imagine for a moment it is on the agenda. That Apple's new head of all design, hardware and software, Jony Ive, was set to impose a new, unified, Aluminium theme. That, just like the Scarlet Witch in House of M, he whispered "No more Skeuomorphs."
Instead of arguing in the abstract about how much better or worse it would be, let's mock it up and see what could that look like...
A unified, aluminium iOS
Back before iOS 6 there were rumors of a complete, consistent re-skinning of the core interface into something more subdued and "silver". That didn't come to pass, though Apple's newest built-in app, Maps, did get a more subdued, more silver make-over, complete with new, floating buttons. Inspired by a discussion with Grant Paul for an upcoming episode of the Debug podcast,
I'm going to use something akin to that as a foundation, with a hint of the WWDC 2012 for the more heavily designed apps. I'm calling it "aluminium" in honor of how Jony Ive (properly) pronounces the word. Here's an example of Find my Friends, iBooks, and Game Center, stripped down and anodized.
Under the theory that consistency is usability, the more lightly-designed built-in apps could also adopt the same look and feel. Here's an example of Settings, Mail, and Safari.
Additional background
A lot has been written about skeuomorphism lately, by a lot of people far more experienced than me. Dave Wiskus, in an article for Macworld, explored the future of Apple design, saying:
Steve Jobs very purposefully built Apple to be a skate-to-where-the-puck-is-going company, and while skeuomorphic design has acted as a bridge between the physical world and digital abstractions, it?s becoming increasingly obvious that the world is comfortable with digital now. Technology is no longer witchcraft to be feared by the masses. We?ve grown accustomed to having phones, tablets, and computers around us to do things. With both visual and interaction design, we?re nearly past the point of real-world metaphors being useful, and the simplest representation is usually best.
John Gruber of Daring Fireball attributes much of this to the evolution from standard to HiDPI displays like Retina:
The trend away from skeuomorphic special effects in UI design is the beginning of the retina-resolution design era. Our designs no longer need to accommodate for crude pixels. Glossy/glassy surfaces, heavy-handed transparency, glaring drop shadows, embossed text, textured material surfaces ? these hallmarks of modern UI graphic design style are (almost) never used in good print graphic design. They?re unnecessary in print, and, the higher the quality of the output and more heavy-handed the effect, the sillier such techniques look.
Marc Edwards of Bjango also cites the print world, but mentions the technical limitations of rival platforms as a contributing factor to their simpler design languages:
In interface design, square finished corners are faster, because there?s no masking. Not including shadows is faster, because there?s less compositing. Drawing a flat colour is faster than drawing a gradient. When you have three or six pixel densities, drawing sharp textures is almost impossible, unless you include bitmap assets for every size you?re targeting.
Sebastiaan de With brought up a counterpoint on Twitter:
Very 'flat' UI is a meaningless reactionary design fad vs. overdesigned UI. Good designers aren't limited by style but taste and discretion.
I'm still of the opinion that it's less about skeuomorphism or it's opposite, digital authenticity, than it is about usability. In some cases, skeuomorphism helps make things discoverable, approachable, and engaging. In others, it just gets in the way.
Check out the examples above and let me know what you think. Would a unified skin across all of Apple's apps be more elegant or just more monotonous? Would a face lift make iOS less "boring" or just less interesting?
Update: Super-designer Louie Mantia brings up a couple of excellent points, and throws in a gorgeous mockup, on Twitter:
it's not about "flat" vs. "skeuomorphic," but more about "chrome" or "no chrome". I think that this might be a more interesting discussion to have than making all UI aluminum.
