Prediction of maximal oxygen uptake from the ratings of perceived exertion and heart rate during a perceptually-regulated sub-maximal exercise test in active and sedentary participants

This study assessed whether the accuracy of predicting maximal oxygen uptake (VO2max) from sub-maximal heart rate (HR) and ratings of perceived exertion (RPE) values was moderated by gender and habitual activity. In total, 27 men and 18 women completed two GXTs to determine VO2max and three perceptually-regulated GXTs, incremented by RPE 9, 11, 13, 15 and 17. The RPE and HR were individually regressed against VO2max (approximately 0.96) to enable predictions of VO2max. The VO2max was predicted from three RPE ranges (9-17, 9-15, 9-13). The RPE ranges were extrapolated to RPE(19), RPE(20) and age-predicted maximal HR (HRmax(pred)). ANOVA revealed no differences between measured and predicted VO2max (P > 0.05) when the RPE range 9-17 was extrapolated to RPE(19) and HRmax(pred). Extrapolation of RPE 9-17 to RPE(20) overestimated VO2max (P < 0.05), but no differences were observed when predicted from the RPE ranges 9-15 and 9-13. The prediction of VO2max was not moderated by gender or activity status. Hierarchical regression analysis revealed that HR explained additional variance in VO2max when added to the RPE (2%). Hierarchical multiple regression analysis also indicated that VO2max was significantly correlated with power output at sub-maximal RPE values of 13 and 15 (P < 0.01) in men and women. The addition of HRmax(pred) improved the accuracy of the prediction equation for men (P = 0.05) but not for women. The study confirmed the validity of estimating VO2max from perceptually-regulated, sub-maximal GXT and indicated the potential utility of regression analysis to gauge appropriate sub-maximal exercise intensities.

基于德尔菲法的区域卫生信息管理平台指标体系构建

目的构建适合区域卫生信息管理平台的指标体系,为卫生行政管理提供有效、经济和便捷的信息化服务。方法采用德尔菲法筛选指标。首先,以电子邮件的方式将问卷发给专家,由专家评分;其次,回收专家评分表进行数据统计分析,根据指标筛选规则来剔除不符合要求的指标;最后,经过2~3轮德尔菲法咨询后形成指标体系。结果经过两轮德尔菲咨询后,专家意见基本一致,两轮专家问卷回收率及有效率均为100%,专家权威系数0.721,专家的权威性较高。按照专家意见,在第一轮咨询后删除16个三级指标,第二轮专家咨询后删除15个三级指标,最后形成包含4个一级指标、13个二级指标、98个三级指标的指标体系。结论应用德尔菲法建立指标体系,具有一定的科学性和权威性,可以为后续平台开发提供依据,进而为卫生行政管理部门提供便捷的信息化服务。     

片姜黄和片子姜黄名称及来源考辨

文章主要通过文献考证的方法,对片姜黄和片子姜黄的名称以及来源进行考辨,为现代临床正确应用古方提供依据。在古代方书中,片姜黄和片子姜黄常互称互代,作为同一种药应用;而在古代本草文献中,两者常常在姜黄名下作为同一品种载述。片姜黄和姜黄在古代方书中亦互称互代,作为同一种药应用;在古代本草文献中在姜黄名下载述片姜黄的功效及形态特征。古代方药文献对于片姜黄的记载基本一致,现代文献对片姜黄来源记载的不一致,与现代对姜黄、郁金以及莪术的来源记载变化有关。笔者认为,片姜黄即古之片子姜黄;在古代其与姜黄系指同一药物,来源亦如姜黄一样并非一种;在现时其与姜黄已作为2种药物,来源单指原植物温郁金;应用古方需了解姜黄与片姜黄古同今异的变化,在临床中正确选药。     

以两个或以上人名命名的综合征ICD-10编码探讨

以两个或以上人名命名的综合征（病）,在编码工作中经常会遇到,编码员对这类综合征（病）名称的发展由来如果了解得不够深入,易导致编码错误.综合征编码原则：不含人名地名时,以“综合征”、“病”、“疾患”或疾病全称作为主导词查找;含人名地名时,直接以人名地名为主导词查找.本文通过对Axenfeld-Rieger综合征、Vogt小柳-原田综合征两例编码的分析,探讨以两个或以上人名命名的综合征（病）编码的方法及注意事项,以便协助编码人员在面对此类问题时更好更准确地进行编码工作,以提高该类疾病分类的准确率,并通过进一步分析国际疾病分类需求与实际编码操作产生的矛盾,对如何更好地实现病案编码理论与实际相结合提出建议.

Job authority and health: Unraveling the competing suppression and explanatory influences

Using data from a 2005 national survey of working American adults (N = 1800), we examine the association between job authority and three health outcomes: physical symptoms, psychological distress, and anger. We also seek to explicate the intervening conditions that suppress and/or contribute to those associations. We observe that higher levels of interpersonal conflict in the workplace and work-to-home interference among those with more job authority suppress the negative association between authority and each health outcome. By contrast, the greater earnings and nonroutine work among those with higher job authority explain their lower levels of physical symptoms, distress, and anger. These observations elaborate on and refine the “stress of higher status” theoretical perspective and illuminate the paradox of the overall null association between job authority and health. Moreover, they draw much-needed attention to the ways that suppression effects can broaden our understanding of workplace inequality, stress processes, and multiple health outcomes.     

大学生归因方式与人格特质及父母教养方式的相关研究

目的探讨大学生归因方式与父母教养方式及自身人格特质三者之间的关系。方法以某高校161名大一到大三学生为被试,对其归因方式、人格特质及父母教养方式进行问卷调查。结果①大学生人格特质中精神质分数越高其归因总分越低(r=-0.215,P<0.01),外倾性分数越高其归因总分越高(r=0.180,P<0.05),神经质分数越高其内控归因的分数越高(r=0.284,P<0.01);②父母的惩罚严厉等因子分越高其大学生归因总分越高(r=0.176,0.165,P<0.05;r=0.271,0.241,P<0.01;r=0.280,P<0.001);③父母感情温暖理解因子分越高其大学生人格特质中的精神质、神经质的分数越低(r=-0.160,P<0.05;r=-0.263,-0.264,-0.240,P<0.01),其外倾性分数越高(r=0.199,P<0.05;r=0.230,P<0.01);父母惩罚严厉、拒绝否认因子分越高其大学生人格特质中精神质和神经质分数越高(r=0.197,0.178,P<0.05;r=0.257,0.208.0.268,0.267,0.299,P<0.01)。结论大学生倾性人格特质及父母的惩罚严厉、过度干涉、拒绝否认等教养方式易形成外控型归因方式,而高精神质的人格特质易形成内控型归因方式。
