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.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
