养生长寿与平衡

我国古代养生之道在经书《周易》中就有记载,老子的《道德经》更是一部关于养生与自然平衡法则的专著。养生与平衡对维护人的整体健康起着绝对重要的作用。 人的整体生命过程就是脏腑阴阳调节及经络调节、气血津液调节、主机升降出入调节的相互作用、不断平衡的结果,以保持人体内外环境的统一,维持人体的生命活动,若生理平衡被打破则会引起疾病发生,甚至危及人的寿命。人的各种生理活动亦有自己平衡运动的规律。 养生在于平衡,生命在于平衡。人体各系统、各器官机能不但要时时处于平衡统一状态,而且还要求在营养、休息、运动、环境、心理等方面保持最佳平衡。这种平衡是保持人体健康的基本条件。 营养平衡 营养过剩则过犹不及,打破了人的生活最佳平衡,正如一些西方经济发达国家流行的“文明病”一样。平时,要谨和五味,不偏食。营养平衡使人能均衡地发育生长。

Remote physiological monitoring: clinical, financial, and behavioral outcomes in a heart failure population.

This article reports on the outcomes associated with remote physiological monitoring (RPM) conducted as part of a heart failure disease management program. Claims data, medical records, data transmission records, and survey results for 91 individuals ages 50-92 (mean 74 years) successfully completing a heart failure RPM program were analyzed for time periods before, during, and after the monitoring intervention. The program was associated with significant reductions in per member per month costs and emergency room and hospital utilization. More detailed analyses were performed for specific gender and age subgroups. Participant surveys indicated high levels of satisfaction, and improvements in self-perceived health status, self-efficacy, and self-management behaviors. This study is the first to assess the impact of a RPM program following removal of the monitoring equipment. The results indicate that RPM, as a component of a traditional disease management program, has a sustained, beneficial effect on participants' lifestyles after the monitoring period has ended.     

A comparison of questionnaire and physiological data in predicting future chronic disease risk factor status in an employee population

BACKGROUND. The ideal screening tool for worksite health screening programs has not yet been identified, and the effectiveness of screening programs in predicting future chronic disease risk factors status is not well understood. This study compared two commonly used screening tools, health-related questionnaires and measurement of physiological parameters, in terms of their ability to predict future chronic disease risk factor status in an employee population. METHODS. Data were collected over a 10-year period from Liberty Corporation employees (N = 723). Baseline evaluation included the administration of questionnaires and measurement of physiological data. Follow-up evaluation measured physiological data only. Regression analyses identified the statistically significant predictors of future risk factor status using 1) baseline questionnaire data; 2) baseline physiological data; and 3) both questionnaire and physiological data as predictor variables. RESULTS. Although both screening methods were able to predict future risk factor status, R 2 values were higher in models including baseline physiological measures than models including questionnaire data only. Adding questionnaire data to physiological data provided little or no additional predictive ability. DISCUSSION. These results suggest that physiological data, particularly baseline measures of a risk factor, are more predictive of future risk factor status than questionnaire data.     

Use of exposure databases for status and trends analysis.

Exposure databases are useful for monitoring status and trends in environmental health. However, other supporting data are usually needed to infer human exposure or internal dose. Program planning and evaluation, environmental health surveillance, epidemiologic research, and contributions to international efforts are four major purposes for monitoring environmental exposure status and trends. Although databases play an important role in monitoring human exposure, certain methodological problems need to be overcome. The work group developed six criteria for meeting information needs for human exposure assessment. Areas that need attention are (1) specification of location, (2) specification of facility and chemical identifiers, (3) documentation of special populations at risk, (4) provision of early warning of new problems, (5) monitoring changes over time, and (6) enhancement of documentation. We tested these criteria by examining six available databases that might be used for monitoring exposure to contaminants in drinking water. Available data fell short of information needs. We drew four conclusions and offered several recommendations for each. First, available data systems lack adequate measures of human exposure. Second, data for monitoring exposures for many important population subgroups and environmental settings are inadequate. Third, an "early warning" system that monitors human exposures is needed. Fourth, designers of data-collection systems should consider the needs of users who monitor status and trends of human exposure.

The LifeShirt system for wireless patient monitoring in the operating room

We examined the functionality and reliability of a wearable physiological monitoring system (LifeShirt) during normal daily activities and in a hospital operating room (OR) environment. The garment collects physiological data such as oxygen saturation, and stores them in a recorder from which it can be read afterwards. Ten normal subjects wore the shirt continuously for 8 h per day. Feedback from the testers was quite positive, although the collected data varied in quality. Ten hospital patients also wore the shirt during endoscopy. The data collected during the hospital stay were qualitatively adequate. Measuring respiratory function caused the biggest problems. The study showed that intelligent garment technology could be used in an OR environment for patient monitoring, albeit not in realtime. It may also be useful in home follow-up.
