Normalizing Heterogeneous Medical Imaging Data to Measure the Impact of Radiation Dose

The production of medical imaging is a continuing trend in healthcare institutions. Quality assurance for planned radiation exposure situations (e.g. X-ray, computer tomography) requires examination-specific set-ups according to several parameters, such as patient’s age and weight, body region and clinical indication. These data are normally stored in several formats and with different nomenclatures, which hinder the continuous and automatic monitoring of these indicators and the comparison between several institutions and equipment. This article proposes a framework that aggregates, normalizes and provides different views over collected indicators. The developed tool can be used to improve the quality of radiologic procedures and also for benchmarking and auditing purposes. Finally, a case study and several experimental results related to radiation exposure and productivity are presented and discussed.     

对精神病患者监护人的干预在减少医疗纠纷中的作用

目的:探讨对精神病患者监护人的干预在减少医疗纠纷中的作用。方法:采用回顾性调查,统计32例医疗纠纷情况并分析原因。结果:产生医疗纠纷的原因中,22例与患者的监护人有较大关系。结论:通过对监护人的干预能减少精神病科的医疗纠纷。     

医学生体力活动水平与生存质量的相关性

目的了解医学生体力活动水平和生存质量现状,探讨两者的关系。方法采用国际体力活动短问卷和世界卫生组织生存质量测定量表简表,对随机整群抽样的660名医学生进行问卷调查。结果在660份有效问卷中,58例(8.8%)体力活动不足,348例(52.7%)体力活动适中,254例(38.5%)体力活动活跃。女生的学生成绩(G=-0.090,P0.05)、父亲文化程度(G=0.095,P0.05)、母亲文化程度(G=0.118,P0.05)、是否生病(χ2=9.510,P0.05)和每日静坐时间(H=7.705,P0.05)均对体力活动水平影响显著。医学生的生存质量在心理、社会关系、周围环境领域得分显著高于全国成人常模。累积Logits模型显示,女生的体力活动适中是生理健康的一个保护性因素,OR=1.89,95%CI为(1.03,3.39)。结论绝大多数医学生的体力活动水平处于适中或活跃的水平,医学生的生存质量较高。医学生的体力活动受诸多因素影响,且体力活动不足会降低其生存质量,尤其是生理健康领域。     

天水医事简略

天水地处甘肃东南部,历史悠久,医疗卫生源远流长,名家辈出,由于古时兵乱灾疫较多,加之造纸术,印刷术落后,使得众多珍贵文献难以保存至今,本文就笔者研习所得做一简要阐述。
