New approach to underweight COPD patients

04.10.2010
Malnutrition often goes hand in hand with COPD and is difficult to treat. In a recent study researchers at the University of Gothenburg, have come up with a new equation to calculate the energy requirement for underweight COPD patients. It is hoped that this will lead to better treatment results and, ultimately, better quality of life for these patients.

Recently published in the International Journal of Chronic Obstructive Pulmonary Disease, the study involved a total of 86 patients with an average age of 64. In contrast to studies in other countries, more than half of the patients were women, whereas previous studies have focused on men.

“We’ve come up with the only equation to date that’s specially designed for COPD patients, and that calculates just how many calories a patient needs,” says Frode Slinde, docent at the Sahlgrenska Academy’s Department of Clinical Nutrition. “We’ve already shown that the existing equations, designed for healthy individuals, do not work well for COPD patients.”

The results of the study offer a more accurate estimate of each patient’s energy requirement, and could lead to a better and more individual nutritional approach. Previously a standard calculation was used to determine a patient’s energy requirement, but the researchers believe that the new equation is more likely to help COPD patients to stop losing weight and even put on weight.

“We can now tailor treatments and quickly evaluate the results,” says Slinde. “A better nutritional status has been linked with patients feeling better and not needing as much care as before, which could cut the cost of care to society in the long run. As far as COPD patients are concerned, a better nutritional status translates into better quality of life and a longer life.”

COPD
COPD, or chronic obstructive pulmonary disease, affects the lungs and airways. Patients have constant problems with their airways and are short of breath. The number of COPD patients in Sweden is estimated at between 400,000 and 700,000 depending on the criteria used by doctors when making the diagnosis. The primary cause of COPD is damage to the mucous membranes as a result of active or passive smoking. Treatments include giving up smoking and medication.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
