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: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
