支气管哮喘患儿中性粒细胞胞外诱捕网水平与患者免疫功能及临床预后的关系

目的探讨支气管哮喘患儿中性粒细胞胞外诱捕网水平与患者免疫功能及临床预后的关系。方法选取本院2017年9月-2018年9月支气管哮喘患者80例作为观察组,并以同期健康体检的30例儿童作为对照组,采用pico Green dsDNA荧光染色定量检测支气管哮喘患者NETs水平,采用T淋巴细胞亚群评价患者免疫功能,对比不同NETs水平患者免疫功能及临床特点,采用Logistic回归分析探讨小儿支气管哮喘急性发作的风险因素。结果观察组白细胞、中性粒细胞、单核细胞、Cf-DNA/NETs水平均高于对照组(P <0. 05),而淋巴细胞水平低于对照组,差异均有统计学意义(P <0. 05)。Logistic回归分析显示,哮喘家族史、呼吸道感染、Cf-DNA/NETs水平上升、有害气体接触、被动吸烟均是支气管哮喘急性发作的独立危险因素(P <0. 05)。结论中性粒细胞胞外诱捕网水平与支气管哮喘患者免疫功能及预后密切相关,值得临床重点关注。     

Development and approval of live attenuated influenza vaccines based on Russian master donor viruses: Process challenges and success stories

Influenza is a viral infection that affects much of the global population each year. Vaccination remains the most effective tool for preventing the disease. Live attenuated influenza vaccine (LAIV) has been used since the 1950s to protect humans against seasonal influenza. LAIVs developed by the Institute of Experimental Medicine (IEM), Saint Petersburg, Russia, have been successfully used in Russia since 1987.In 2006, the World Health Organization (WHO) announced a Global action plan for influenza vaccines (GAP). WHO, recognizing potential advantages of LAIV over the inactivated influenza vaccine in a pandemic situation, included LAIV in the GAP.BioDiem Ltd., a vaccine development company based in Melbourne, Australia which held the rights for the Russian LAIV, licensed this technology to WHO in 2009. WHO was permitted to grant sub-licenses to vaccine manufacturers in newly industrialized and developing countries to use the Russian LAIV for the development, manufacture, use and sale of pandemic and seasonal LAIVs. To date, WHO has granted sub-licenses to vaccine manufacturers in China (Changchun BCHT Biotechnology Co., Ltd.), India (Serum Institute of India Pvt. Ltd.) and Thailand (Government Pharmaceutical Organization). In parallel, in 2009, IEM signed an agreement with WHO, under which IEM committed to supply pandemic and seasonal candidate vaccine viruses to the sub-licensees.This paper describes the progress made by collaborators from China, India, Russia and Thailand in developing preventive measures, including LAIV against pandemic influenza.     

工作坊模式在护生压疮护理带教中的应用效果分析

目的探讨工作坊模式在护生压疮护理带教中的应用效果,为临床护理带教提供参考。方法选取2018年7月—2019年6月在医院实习的120名护生作为研究对象,随机分为对照组和观察组,各60名护生。对照组采用传统带教法进行压疮培训,观察组采用工作坊教学模式进行培训。培训结束后比较两组护生压疮知识的掌握程度即理论考核、技能操作成绩,教学效果满意度。结果观察组护生对压疮知识的掌握程度即理论考核成绩、技能操作考核成绩远远高于对照组,两组差异具有统计学意义(P<0.05)。95%的观察组护生对工作坊教学模式的效果表示满意,认为工作坊教学模式能够提高学习的兴趣、主动性和临床实践能力,对临床工作有很大帮助。结论工作坊教学模式应用于压疮护理的临床带教,能让护生亲身体验压疮护理的过程,并参与其中,将理论与实践相结合,更好地活跃课堂气氛,启发护生思考,提高护生对压疮理论和技能的掌握,为临床实际工作中压疮护理质量的提高奠定基础。     

小儿化脓性脑膜炎76例临床分析

目的：探讨小儿化脓性脑膜炎的临床疗效和临床观察。方法回顾分析76例小儿化脓性脑膜炎患者的临床资料。结果76例患儿中，54例患儿治愈,16例患儿好转,6例患儿转科治疗。治疗前患儿脑脊液检查外观混浊的检出率和球蛋白阳性的检出率分别为73.7%和92.1%,显著高于治疗后的外观混浊的检出率7.9%和球蛋白阳性的检出率5.3%，治疗前后对比差异具有统计学意义（P<0.05）。结论对接诊的疑似化脓性脑膜炎的患儿及早地诊断、治疗，可以有效减少患儿并发症及后遗症的发生，提高患儿的治愈率。     

Neighborhood: A Conceptual Analysis

Researchers interested in measuring neighborhood‐level effects should understand how “neighborhood” is defined within nursing sciences and other sciences, and the inherent strengths and weaknesses of current research methodologies. This concept analysis provides clarity around the concept of neighborhood within the context of health, analyzes the current state of development of the neighborhood concept, and proposes areas for future nursing research. Using the Rodger's Method of analysis, the concept of neighborhood within nursing and public health research is described based on existing literature. The concept's attributes, related concepts, antecedents, and consequences are given from the literature. Comparisons of the use of neighborhood are made between nursing, public health, sociology, and other sciences. The evolution of the concept of neighborhood throughout history is described, and important implications for future research are discussed.     

Are Medicare's Nursing Home Compare Ratings Accurate Predictors of 90-Day Complications,Readmission, and Bundle Cost for Patients Undergoing Primary Total Joint Arthroplasty?

Background

Nursing Home Compare (NHC) ratings, created and maintained by Medicare, are used by both hospitals and consumers to aid in the skilled nursing facility (SNF) selection process. To date, no studies have linked NHC ratings to actual episode-based outcomes. The purpose of this study was to evaluate whether NHC ratings are valid predictors of 90-day complications, readmission, and bundle costs for patients discharged to an SNF after primary total joint arthroplasty (TJA).
