Physical symptoms that impact quality of life, such as nausea and shortness of breath, may predict shorter survival for patients with terminal cancer.
A new study published July 26, 2004 in the online edition of CANCER, a peer-reviewed journal of the American Cancer Society, finds a patients symptoms and results of quality of life assessments may provide important clues to an individual patients prognosis. Psychosocial factors, such as anxiety or spiritual distress, did not predict shorter survival.
In order to give the most appropriate treatment options to newly diagnosed cancer patients, physicians often assess a patients health-related quality of life (hrQoL), along with tumor characteristics that predict the aggressiveness of the disease and, ultimately, outcome (i.e., response rate to treatments, overall survival, time to progression, and survival in years). In the field of palliative care, length of survival and quality of life are paramount. Research has demonstrated that clinical factors and tumor characteristics predict survival in terminal cancer patients, but there is limited data on the predictive value of hrQoL measures, such as physical and psychological symptoms. Existing research suggests that physical symptoms, not psychosocial symptoms, predict length of survival. However, the conclusions of these studies are weakened by methodological shortfalls.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
