Space-time database for standardization of adult magnetocardiogram-making standard MCG parameters

Background: The magnetocardiogram (MCG) is a promising medical tool for detecting and visualizing abnormal cardiac electrical activation in heart-disease patients. However, there is no large-scale MCG database of healthy subjects, and there is little knowledge of gender- and age-related influences on MCG data.
Methods and Results: We obtained MCG data from 869 subjects (554 men, 315 women) using a conventional 64-channel MCG system, which covers the whole heart. Electrocardiogram (ECG) data were also obtained; 464 people (268 men, 196 women) were identified as a normal group using ECG data. Time intervals (PQ, QRS, QT, and QTc), current distributions (maximum current vector (MCV), and the total current vector (TCV)) of MCG data of the 464 normal subjects were analyzed to obtain basic MCG parameters.
Although mean values of PQ and QRS intervals of the male subjects were slightly longer than those of the female subjects, no intervals were correlated with gender or age. The correlation between PQ intervals of ECG and those of MCG was better than the correlation between QRS and QT intervals of ECG and those of MCG. Both MCV and TCV angles were much smaller than the electrical-axis angle in ECG. Although TCVs of the QRS and T waves were stable, the women's mean T-wave-TCV angles significantly increased with age. The maximum amplitude of the P wave was about 1.7 pT, and the value of the QRS complex was about 20–25 pT. Moreover, the T-wave amplitude decreases with age.
Conclusion: The MCG standard space-time parameters determined here provide a normal range for MCG parameters.     

在规范化辨证基础上构建量化辨病论治体系

证型的规范化研究是证本质研究的前提与基础,但规范化辨证标准不一的混乱状况依旧存在,无法真正指导临床治疗,这主要是因为研究的思路与方法不恰当。在辨病分型的基础上进行基本证候研究是证型规范化研究的主要方法,准确定量症状是证型规范化研究结论真实性和可靠性的有力保证,正确选择统计学方法是确定辨证阈值强有力的技术支持。采用统一量表,开展专家研讨,用复杂性科学理论,对证候进行处理是当前证型规范化研究的最好方法。证型与理化指标的相关性研究无法反映证的全面情况,应在规范化辨证的基础上,针对疾病的主要病理变化进行辨病论治,确立治疗原则。

Computing hospitalization rates in presence of repeated events: impact and countermeasures to avoid misinterpretation

Rationale, aims and objectives The admission rate, including both first and recurrent events, is a clear overall measure of hospital utilization, its variability accounting for individual propensity to disease recurrence. Method In this paper, we compared two variance estimators derived from the Poisson and negative binomial distribution of directly and indirectly age/gender‐standardized hospitalization rates allowing for multiple events. The latter approach accommodates departures from the assumption of randomness of repeated events required by the Poisson distribution. We apply these methods to a retrospective cohort based on hospital discharge data in 2001 of Piedmont (north‐western Italy) residents. Results Estimated standard errors under the negative binomial for both directly and indirectly standardized rates result in almost twice those under the Poisson distribution. Conclusion Our analysis confirms that ignoring the typical non‐random nature of repeated events underestimates the true variance of rates and can lead to biased optimistic interpretation of study results.
