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.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
