 Overnutrition is not beneficial in terminal patients according to the Chiu and Easson studies. As the investigators know, few studies focus on REE in terminal patients. In this study, samples are from a hospice palliative ward or from hospice home care patients in a medical center in mid-Taiwan. About 100 patients will be recruited. The investigators will analyze the relationship between REE and its related factors. After finishing the study, they will provide more evidence for treating cachexia in terminal patients.
