脑科戒毒手术被叫停的医学伦理学思考

曾被大力推广的脑部手术戒毒项目,最近被卫生部紧急叫停。手术被“叫停”的原因主要是:防止违背生命伦理学原则,采用优后原则和遵循手术的临床验证原则。医学科研工作者在科技和利益面前首先应充分考虑到生命伦理学的基本原则。     

Medicare and Medicaid Reimbursement Rates for Nursing Homes Motivate Select Culture Change Practices But Not Comprehensive Culture Change

Components of nursing home (NH) culture change include resident-centeredness, empowerment, and home likeness, but practices reflective of these components may be found in both traditional and “culture change” NHs. We use mixed methods to examine the presence of culture change practices in the context of an NH’s payer sources. Qualitative data show how higher pay from Medicare versus Medicaid influences implementation of select culture change practices, and quantitative data show NHs with higher proportions of Medicare residents have significantly higher (measured) environmental culture change implementation. Findings indicate that heightened coordination of Medicare and Medicaid could influence NH implementation of reform practices.     

城乡医疗救助制度之现状､问题与对策

城乡医疗救助制度对于缓解贫困群众就医难,实现病有所医具有重要意义。作为构建多层次医疗保障和卫生服务体系的重要组成部分,医疗救助制度在取得巨大成就的同时也存在政策导向偏差、救助对象覆盖不全面、资金筹集机制单一、起付线和救助上限的设置缺乏科学性等问题。医疗救助制度应该从取消各种不合理限制,拓宽筹资渠道,实现医疗救助管理独立化和加快医疗救助法制建设等方面加以改善。

政府管制变迁下 IPO资源配置效率的实证研究

文章借鉴Jeffery Wurgler资源配置效率模型,实证检测了我国IPO市场1992～2013年各年度的资源配置效率,针对政府管制程度不同阶段下的整体配置效率进行了对比,深入挖掘了国有企业比例与上市公司质量对资源配置效率的影响。实证结果表明：政府行政管制的存在确实限致了我国IPO市场资源配置效率功能的发挥,政府管制降低了资本市场资源配置效率;政府管制下国企上市较多以及上市公司质量差的年份对IPO资源配置低效率的负面影响更大。据此,提出了加强IPO市场化制度改革,推进国有企业改制等措施来提高IPO市场资源配置效率的建议。     

肿瘤科PICC常见并发症及其处理措施探讨

目的探讨PICC导管在恶性肿瘤化疗患者中的各种常见并发症及其处理措施。方法对300例肿瘤患者进行置管给药并观察置管的临床效果,及其引发的各种并发症。结果发生PICC相关性并发症38例(12.67%),行Logistic回归分析。结论影响留置PICC导管并发症的因素复杂,管理好老年患者、加强培训提高置管水平、实施PICC健康教育、尽量缩短留置时间可以减少PICC导管相关性感染发生,也能避免其他各种常见并发症。     

Transitions to adulthood in contexts of economic crisis and post-recession. The case of Argentina

The possibilities that are available to youth in contemporary Western societies are highly sophisticated and related mostly to the transition between secondary school and higher education, the first job placement, independent housing, lifestyle construction and the consumption of goods produced by cultural industries in a globalist world. Secondary education represents a main factor in terms of socialisation, training, access to employment, citizenship and youth identity construction, making it a key for public policies aimed at youth in Latin America. The article presents the initial results of a research project on transition processes from secondary school to employment in Argentina. The findings are based on statistical information and the empirical analysis of data gathered in two very different economic and social contexts: the first was one of the worst social and economic crisis in the country's history (1999–2003), and the second was a long period of economic growth and increased social welfare (2004–2012). The data are presented in response to the following question: How do different economic contexts influence the transitions of youth in different social class contexts? By answering this question, the significant role of public policies in generating better living conditions for youth becomes clear.
