DETROIT The fatigue experienced by patients undergoing cancer treatments has long been recognized by health care providers, although its causes and ways to manage it are still largely unknown.
A Wayne State University researcher believes the condition affects some patients much more than others and is trying to determine the nature of that difference.
Horng-Shiuann Wu, Ph.D., assistant professor of nursing in the College of Nursing, has made an effort to chronicle the parameters of what she calls sudden exhaustion syndrome. Her study, "Definition, Prevalence and Characteristics of Sudden Exhaustion: A Possible Syndrome of Fatigue in Cancer," recently published in the journal Supportive Care in Cancer, is an effort to differentiate between types of cancer-related fatigue (CRF), a condition that affects upwards of 90 percent of patients who undergo major treatments and 30 to 67 percent of cancer survivors.
"CRF is something that goes far beyond just being tired," Wu said. "It's more draining, more intense, lasts longer than typical fatigue and is often unexpected."
As a graduate student, Wu became interested in a subset of patients who reported fatigue as a "hit-the-wall" moment that came on suddenly, left them barely able to move and often forced them to lie down immediately until the episode passed.
CRF has been well documented, but while many clinicians and researchers have heard anecdotally from patients about suddenly "hitting the wall," such reports have not been addressed directly by studies.
Wu's team studied 114 breast cancer chemotherapy patients aged 31 to 67 from a Midwestern clinic and an urban teaching hospital. Participants were screened for sudden fatigue and completed a questionnaire on the day of their chemotherapy treatment. Descriptive statistics were used to examine the prevalence and clinical characteristics of sudden fatigue episodes, including an intensity rating system from one to 10, the latter level being the highest.
Just under half (46 percent) of participants experienced sudden fatigue. Of those, 81 percent reported more than one episode per day, with 77 percent of episodes taking place during activities between 10 a.m. and 5 p.m. Ninety percent of patients described the intensity as severe.
Most episodes lasted an hour or less, but some lasted up to eight hours. Some patients had to sleep; others did not. Many reported concurrent symptoms including weakness, dizziness, pain, sweating, nausea and shortness of breath.
"We learned that this is something that's really happening and most patients' lives are affected by it," Wu said.
Because the sudden onset of such episodes distinguishes them from what's normally thought of as CRF, she believes "sudden exhaustion syndrome" is a better description.
"Patients can suddenly become so exhausted they cannot move at all," Wu said. One participant experienced an onset while being surveyed, causing her eyelids to droop and rendering her unable to form words.
She said the study shows that patients undergoing treatment endure a lot, and she is interested in looking at which syndrome characteristics particular patients experience, along with degrees of intensity and concurrence.
Wu also would like to know why some patients feel compelled to sleep and others do not, and what symptom changes signal to each person that an episode is ending. She is especially curious about patients who seem to experience little or no CRF.
The condition may even continue for many cancer survivors even after they've finished treatment. Wu believes, however, that in the absence of empirical evidence of that continuation, further research is needed.
For now, Wu said oncology professionals need to recognize the syndrome and educate patients to enhance a sense of control and prevent harm.
"Cancer is not going away anytime soon," she said. "Most people experience their illness through the symptoms, not the illness per se. But we can manage a symptom, even if we can't cure the illness yet."

MakerBot unveils prototype Digitizer Desktop 3D Scanner, promises easier 3D printing
Well, that was quick. Bre Pettis just started delivering South By Southwest's opening remarks and may well have taken the wraps off the biggest news of the show. Of course, we'll still have to hang out in Austin for a few more days just to, you know, totally make sure, but this really does feel like a doozy. As the MakerBot CEO puts it, "It's a natural progression for us to create a product that makes 3D printing even easier" -- but, let's be honest, few of those who don't have a vested interesting in moving some 3D printers are running around calling the whole process particularly "easy." And while consumer-facing devices like the Replicator, CubeX, Solidoodle, et al. have gone a ways toward making the technology more accessible for laypeople, there's still a fundamental breakdown: the creation of models to be printed.
The maker community has helped on that front, as well, with MakerBot's Thingiverse serving as an unparalleled resource for 3D images, meaning that, once your printer's all set up and calibrated, you can download and print to your hearts delight -- but what if, say, you want to print up something that some kindly soul hasn't designed for you? You could learn a CAD program -- or you could invest in an industrial 3D scanner. The latter option has lead to something of a land rush of companies and individuals looking to break things wide open with an affordable, consumer-facing offering. And while MakerBot still seems a ways away from the final product, the company used SXSW as a platform to unveil a prototype of its MakerBot Digitizer Desktop 3D Scanner.

Hugo Chavez era ends: Will US-Venezuela relations improve?
Hugo Chavez passing may intensify the US dialogue with Venezuela on several key issues, including counterterrorism and energy. But many expect healing to take time.
Supporters of Venezuela's President Hugo Chavez in Caracas, Venezuela, Tuesday, yell 'Long Live Chavez!' and sing their nation's anthem after learning that Chavez has died.
Ariana Cubillos/AP
EnlargeThe passing of Hugo Ch?vez removes one of the prickliest thorns in US relations within its own hemisphere and could portend brighter days for US-Venezuela relations ? eventually.

But any warming in ties won't happen overnight, especially after the Venezuelan government accused the United States, on the same day Mr. Ch?vez died, of having a hand in causing his demise. ??
Yet as the United States and Venezuela move on from more than a decade of rocky relations that correspond to Ch?vez?s 14 years as president, one short-term move that the two countries could make to symbolize a turning of the page would be to again send ambassadors to each other?s capitals, some regional experts say.
The US and Venezuelan embassies in those capitals have sat without ambassadors since 2010, when each government rejected the credentials of the other country?s ambassador. Diplomatic relations were even severed for a short period beginning in September 2008.
Yet even if ambassadors are exchanged in the coming weeks or months as a goodwill gesture, no one expects tensions to evaporate from the relationship overnight. Any doubts about that were erased Tuesday when Venezuelan officials expelled two US diplomats it accused of conspiring to destabilize the government.?
Ch?vez may be gone, but his supporters will still have their hands on the country?s levers of power, Venezuela analysts say ? and could keep them there for some time to come.
And the fiery-tongued leader?s anti-American rhetoric won?t lose its influence any faster than will suspicions about US intentions, some regional experts predict.
?Ch?vez conditioned much of Venezuela to think negatively of the US,? says Eric Farnsworth, vice president of the Council of the Americas and Americas Society in Washington. Many Venezuelans won?t forget quickly Ch?vez?s claims, especially early in his rule, that the Central Intelligence Agency was trying to assassinate him or that the US was behind a 2002 military coup that briefly forced him from office.
?Healing is going to take time,? he says, ?and I?m not convinced that whoever takes over after Ch?vez will be that interested in healing.?
Some are more optimistic.
?I think Venezuela does care about [its relations with the US],? says Miguel Tinker Salas, a professor of Latin American studies and Venezuela specialist at Pomona College in Claremont, Calif. ?Even under Ch?vez there was talk of hoping to see a rapprochement, and I think most Venezuelans feel there is nothing to be gained from maintaining a contentious relationship.?

Dinner plans? Obama and Senators meet for swanky eats
Painful spending cuts may have led the White House to halt public tours, but President Barack Obama and Republican Senators could need to loosen their belts, not tighten them, after their peacemaking dinner at a super-swank Washington, D.C., restaurant on Wednesday. How swank? The eatery features a menu with a $1,776?per person?price tag, excluding tax and tip.
Obama invited the GOP lawmakers to the tony Jefferson Hotel, home to Plume restaurant, in a bid to break the partisan logjam and forge a deficit-cutting deal. Plume is widely considered among D.C.'s finest.
The group ?will be dining from the 'Plume' menu," a hotel source told Yahoo News.
So, alas, they may not be ordering the actual "1776" menu, or even the more-modest-but-still-lavish $85 menu?one dollar for every billion of the $85 billion in cuts slated to go into effect this year. Who's going to pick up the tab? White House officials wouldn't say on the record.
So what makes the $1,776 menu so special?
?It pairs the evening's ever-changing tasting menu with wines that date, collectively, over the past 237 years,? according to hotel spokeswoman Meaghan Donohoe.
?For instance, this could include a 20-year-old champagne, Grand Cru White Burgundy, a Bordeaux from one of the five 1st growths, and a glass of Madeira from 1790,? she said.
