Improving self-care efficacy and quality of life with a self-management program among patients with chronic obstructive pulmonary disease: A quasi-experimental study.

Self-management helps patients understand their illnesses and learn about disease-related skills so they can better manage their situation. However, published studies on the effectiveness of self-management for chronic obstructive pulmonary disease (COPD) are heterogeneous. Quasi-experimental design was used to investigate the effectiveness of a self-management program in self-care efficacy and quality of life in patients with COPD. Sixty participants who had experienced COPD were assigned to control group (usual care) or experimental group (self-care program) (1:1 ratio) according to a purposeful sampling at a Medical Center in Taiwan. The Medical Research Council dyspnea scale, the COPD Self-Efficacy Scale, the Clinical COPD Questionnaire were used to analyze data. The Medical Research Council dyspnea scale was more significant improvement in the 2 months after discharge in the experimental group than in the control group. The COPD Self-Efficacy Scale and Clinical COPD Questionnaire scores in the experimental group within 3 months after discharge were significantly improved compared with the control group. These findings demonstrate the application and initial effect of this self-management program.

Chemical composition and bioactivities of the marine alga Isochrysis galbana from Taiwan.

The present study investigated the chemical composition of Isochrysis galbana Parke, a marine microalga which is widely used as a feedstock in aquaculture. From gas chromatography/mass spectrometric analysis the mono-sugar compositions of I. galbana were 2.1% fucose, 2.5% rhamnose, 2.7% arabinose, 8.5% xylose, 15.7% mannose, 32.7% galactose and 35.8% glucose. The polysaccharides of I. galbana were able to induce prointerleukin-1beta (pro-IL-1beta) protein expression within murine macrophages. Furthermore, five kinds of chlorophyll and one sterol were separated from the ethanolic extracts, including pheophorbide-a, ethyl pheophorbide-a, 10S-10-hydroxypheophytin-a, 10R-10-hydroxypheophytin-a, (132-R)-pheophytin-a, and brassicasterol. In addition, the major soluble components of the ethanol/n-hexane extract were 9-octadecenoic acid (E) (38.4%), hexadecanoic acid (23.3%), tetradecanoic acid (15.7%), and octadecanoic acid (7.2%), but only a few polyunsaturated fatty acids were found, such as 9,12,15-octadecatrienoic acid (1.9%), 9,12-octadecadienoic acid (Z,Z) (3.4%), and docosahexaenoic acid (0.2%). This is the first occasion that polysaccharides from I. galbana have been demonstrated to exert immunomodulatory properties by the induction of IL-1 within macrophages.
