This paper, updating the findings of an earlier study, provides additional evidence that sheet metal workers in the construction trades are at increased risk for asbestos-related disease. A proportional analysis of cause of death among 331 New York sheet metal workers found a significantly elevated PMR for lung cancer (PMR = 186). In addition, there were six deaths attributable to mesothelioma (three classified as lung cancer deaths) and three death certificates mentioned asbestosis or pulmonary fibrosis, although none of these three deaths were attributed to these diseases. 相似文献

Exposure to mineral dust was studied among construction workers (N = 437) with the aid of a questionnaire and a chest X-ray examination of the lungs. The results of the questionnaire showed that 81% of the construction workers had been exposed to asbestos. Exposure had occurred in all of the occupational groups studied. Pleural plaques and/or lung fibrosis (ILO greater than or equal to 1/1) were found in 26% of the examined workers; the prevalence varied from 18 to 40% among the various occupational groups. Comparison with a representative sample of the Finnish male population from another investigation indicates that the frequency of lung fibrosis (ILO greater than or equal to 1/1) is at least two times higher among the examined construction workers than among the general population. It seems likely that exposure to asbestos dust can be considered an etiological factor for an appreciable number of the X-ray findings. 相似文献

Objective: To explore patterns in the practice of nursing and patient outcomes.
Design: Qualitative field research.
Population, Sample, Setting: Populations were critical care nurses and critically ill adult patients in the 10-bed medical critical care unit of a 900-bed teaching hospital. A convenience-purposive sample of 27 nurses and 31 patients was studied in 1985.
Methods: Six months of participant observation, unstructured interviews, and the constant comparison method of grounded theory.
Findings: Markedly different patterns were found in expert and nonexpert practice. The substantive theory of conversion helped explain how the majority of nonexpert nurses advanced their practice. The metaphor of catalyzed conversion captures how a unit-based expert nurse serves as a catalyst to advance the practice of nonexperts. Presence, defined as the way of being within a given clinical context, differentiated nurses.
Conclusions: (a) Expert and nonexpert practices are substantively different, (b) Expert and nonexpert practice results in different patient outcomes, (c) Conversion helps explain changes in nonexpert practice.
Clinical Implications: A unit-based expert nurse can increase patient-focused care. 相似文献

目的 探索医学生团队对大学英语思政教学资源的发掘与整合,并建设医学院校大学英语课程思政教学资源库,为医学生英语教学与思政教育的融合提供可行性经验。方法 对某医学院校1 030名学生进行问卷调查,并采用SPSSAU统计软件对调查结果进行分析,了解学生对英语教学与思政教育融合的态度与需求、大学英语思政教学资源库的建设方式,以及资源的呈现方式和类型。基于问卷结果、教材主题、教学模块与学生专业,采用内容分析与归类法,建设符合医学生期望的大学英语思政教学资源库。数据均以占比百分率的形式呈现。结果 ①836名学生认为大学英语有必要与思政教育融合,希望通过日常生活(731人)、医学背景知识(664人)、社会实践(622人)、新闻时事(604人)等相关的视频、音频建设思政资源库,并以“教师讲授+课堂讨论”(528人)的形式引导学生学习上述资源。②根据教材主题匹配问卷结果中的思政融入点,根据单元模块内容进一步细化思政融入点为普适性与医学专属思政教学元素两类,最终建成了医学院校大学英语思政教学资源库。结论 好的课程与资源是师生共研共建的。 相似文献

目的:将T细胞抗原受体基因TCA-12-2和TCB-7.1共同构建在真核表达载体pDC315,用于哺乳动物细胞293转染研究。方法: 将分离得到的淋巴细胞总RNA反转录合成cDNA,以此为模板进行PCR扩增得到TCA-12-2基因;以实验室保存含TCB-7.1基因的质粒为模板,扩增得到TCB-7.1基因。随后酶切,连入载体pIRES2-AcGFP1,通过亚克隆连入载体pDC315,得到重组质粒pDC315-TCA-12-2-TCB-7.1。重组体质粒经酶切鉴定后,并对插入的TCA-12-2和TCB-7.1基因片段进行测序,将鉴定好的阳性重组质粒用脂质体介导转染293细胞,并通过RT-PCR和流式细胞仪检测TCA-12-2和TCB-7.1基因的表达情况。结果: TCA-12-2和TCB-7.1可以同时构建在载体pDC315上,RT-PCR和流式细胞仪检测发现TCA-12-2和TCB-7.1基因可以成功在293细胞上表达。结论:成功构建了含TCA-12-2和TCB-7.1基因的双表达载体。 相似文献

DICOM医学图像的存储与管理 总被引:11,自引:0,他引:11
随着数字化医学成像设备在医院的广泛使用,对医学图像及相关数据的存档管理以及在不同科室之间的数据共享的要求越来越迫切,这就需要建立PACS(图像存档和通讯系统),这方面国外已经发展了很多年,我国目前处于起步阶段.本文参照PACS系统的一个已经被国际认可的医学图像标准即医学成像和通讯标准DICOM(digital imaging and communication in medicine),研究了标准的各个部分,特别是兼容性、信息对象定义(IOD)、服务对象对类(SOP)、数据编码等部分,就具体实现PACS系统的一个重要方面即医学图像的存档和管理做了深入的探讨,在此基础上建立了医学图像数据库系统,为实现医学图像信息的网络共享打下了基础. 相似文献
