In this paper, the author presented a strategy for classifying local multi-channels MS waveform, triggering by a single event. There were three steps to achieve the goal. Firstly, based on STA/LTA method, the first arrival and terminated time had been picked up, using the MS signal preprocessed; secondly, the author extracted the waveform features, time-frequency (L,f), amplitude (A), statistics of amplitude distribution (AD) and threshold algorithm (TS), and correlation coefficient (R); thirdly, before establishing an effective judgment mechanism, this method employed a hierarchical recognition framework with 3 layers, which integrated preliminary judgment, combined recognition and optimization judgment. This method was validated through analyzing a coal mine visual event in Shandong Province, and the result shows that it is successfully used to classify electromagnetic interference wave, background noise and MS events. The result can basically meet the requirements of classification accuracy. [ABSTRACT FROM AUTHOR]

Background: Measurement of cancer-related fatigue and nutrition in the same colorectal cancer patient group using fast-track surgery has never been examined previously. The association between fatigue and nutritional status in the same patient group is thus worthwhile to be investigated., Objective: The aim of this study was to evaluate the relationship between fatigue and nutrition risk factors in colorectal cancer patients with fast-track surgery., Methods: This is a single-arm, observational study. Seventy eligible postoperative patients with colorectal cancer fast-track surgery were enrolled in this study. Patients completed the Cancer Fatigue Scale and the Patient-Generated Subjective Global Assessment (PG-SGA) besides routine perioperative laboratory examination., Results: In this study, all patients were found to have cancer-related fatigue; 20% of the patients had severe fatigue. Furthermore, 94.29% of the patients were malnourished according to the PG-SGA score; the average was 15.585.18. Fatigue severity was significantly, positively correlated with nutrition status. White blood cells and serum calcium were significantly, positively related to both Cancer Fatigue Scale and PG-SGA scores., Conclusion: Fatigue and malnutrition commonly exist in patients with colorectal cancer experiencing fast-track surgery. Fatigue may reflect the nutritional status in this group of patients., Implications for Practice: Clinical nursing staff need to evaluate patients' fatigue status and nutritional status to provide the suitable clinical intervention when needed.

Background: Dynamic changes of cancer-related fatigue (CRF) among hospitalized patients with colorectal cancer were determined., Materials and Methods: This longitudinal, descriptive study involved 96 hospitalized patients with colorectal cancer, all recruited from a tertiary general hospital in Guangzhou, China. Patients completed questionnaires three times to assess the degree of fatigue, and measurement points were within one week of admission, at 2 to 3 days after surgery and 3 weeks after surgery., Results: Significant differences among the three measurement points (p<0.01) were observed. The scores of fatigue in the second survey were the highest, followed by the third and first surveys. Colon cancer patient scores were higher than those of rectal cancer patients with a significant difference (p<0.05). Colorectal patients experienced different degrees of fatigue at different periods during hospitalization., Conclusions: This study highlights the importance of interventions that are carefully tailored to patients based on the characteristics at different periods to alleviate fatigue.

Aim: This study aimed to investigate the factors associated with the health behavior of hypertensive elderly patients., Methods: This cross-sectional survey used a general data scale, a health conception scale, a scale for self-rated abilities for health practice, and health-promoting lifestyle profiles to investigate the health behavior of hypertensive elderly patients from clinical check-up to hospitalization., Results: The health behavior score of hypertensive patients was 72.25 ± 16.66, and 23.8 % of the patients had high scores. The health-promotion score was positively correlated with those of health conception, self-efficacy, and education level, but negatively correlated with that of unhealthy habits (P < 0.05)., Conclusions: Health practitioners should promote the health conception, enhance the self-efficacy, and improve the health behavior of hypertensive elderly patients.
