背景与目的 对卫生保健干预措施进行决策权衡需要有不良和有益的可靠证据,然而绝大多数系统评价针对的是研究方法非常成熟的随机对照试验及其有效性评价,系统地评价不良反应的方法尚未完善,对研究者而言,能作为相关指南的资源很少.为此,作者在文中报告了对不良反应进行系统评价的新近体会,同时提出进一步实践和研究的建议.方法 描述并比较3个包含不良反应评价的药物干预的系统评价的方法学,重点评价其研究问题、研究设计和质量评价.结果 1个研究关注于如何根据提供的特殊不良反应数据建立卫生经济学模式,而其它两个研究涉及更广泛的问题.尽管每个评价对纳入标准的定义不同,但它们均纳入了随机和观察性数据.对研究质量的评价采用了标准方法.由于研究设计不良、报告不充分和现有研究工具有限,在运用纳入标准和评估研究质量时,研究者遇到了各种问题.最终发现,3个评价都做了大量的工作,但对卫生保健决策者有用的资料不多.研究者确认,改善的关键在于如何提出系统评价的问题和发展不良反应研究的质量评价方法学.结论 若不良反应的系统评价只专注于一个中心问题,那么它会提供与临床决策更相关的资料,也有利于明确纳入系统评价研究的类型.系统评价中不良反应的质量评估的方法学需要进一步完善.
European system for cardiac operative risk evaluation(EuroSCORE) is one of the widely used and influential cardiac surgery risk assessment system. It was originally used to predict the quantitative score of probability of death after cardiac surgery. After that, it has been developed to predict long-term mortality and survival rate, ICU residence time, treatment costs, main complications and so on. EuroSCORE Ⅱ is the latest version, which is more accurate in predicting mortality, long term survival rate than the old one. But there are also some limitations as predicting limited range of the end, underestimating the mortality of critically endangered patients, lacking adequate preoperative risk factors and so on. This review article focuses on the production, development and clinical application of EuroSCORE.
目的 探讨围手术期患者静脉血栓预防的分级护理方法，为静脉血栓的预防提供实证依据。 方法 2009年5月－2012年1月，以某市级乙等综合性医院各科室手术患者为对象，引入量化工具评估患者围手术期静脉血栓发生的危险，并根据评估结果采取分级护理方法进行防治，并在患者出院时用彩色多普勒超声判断是否存在静脉血栓，以验证分级护理防治效果。 结果 纳入的318患者经评估均存在发生静脉血栓的风险，其中低度危险患者65例，中度182例，高度危险71例。经分级护理治疗，出院时均未发生静脉血栓症状、肺栓塞。 结论 分级护理方法安全、简便，可操作性强，便于围手术期患者静脉血栓的早期、普遍预防，值得推广。
Objective To explore the methods of intervention for street-based female sex workers (FSWs) by assessing the intervention process, and evaluate the effectiveness. Methods By cluster sampling procedure, many streetbased female sex workers in Yuzhong district were intervened systematically after informed consent. Before and after the intervention, questionnaire survey was conducted to understand their KAP towards AIDS and analyzed the results of the questionnaire and the effectiveness of intervention. Results The recognition rate abut AIDS knowledge was improved markedly, from the previous 28% to the later 70.5%; condom use in last act increased the previous 59% to the later 75%, consistent use in recent month changed from 4% to 26%; Peer education was trained. Conclusion systematical intervention among street-based female sex workers is critical for spread of AIDS.
ObjectiveTo systematically review the studies on the clinical comprehensive evaluation system of drugs at home and abroad. MethodsThe PubMed, EMbase, Cochrane Library, CNKI, WanFang Data, VIP and CBM databases were electronically searched to collect the literature and policy documents of the clinical comprehensive evaluation system of drugs from inception to October 31, 2022. The evaluation organization, evaluation perspective, application scope, domains and criteria were sorted out, and the evaluation of different types of drugs was analyzed in detail. ResultsA total of 101 clinical comprehensive evaluation systems of drugs were included. The publishing time was from 2009 to 2022, and the number of published articles increased. The first author mainly came from 26 countries, including China (n=34), Canada (n=11), the United States (n=10), and Spain (n=10). Forty-seven articles reported the evaluation perspective. All evaluation systems could be used for drug evaluation, of which 43 could be used as universal evaluation tools, and 58 could be used for the evaluation of specific drugs, mainly including anti-tumor drugs (n=15), orphan drugs (n=10) and traditional Chinese medicine (n=7). The number of evaluation domains varied from 2 to 22, and the number of criteria varied from 4 to 56. Among them, economics (n=73), effectiveness (n=72), safety (n=54), disease demand/burden (n=34), and innovation (n=24) were the most frequent evaluation domains. ConclusionThe research on clinical comprehensive evaluation of drugs at home and abroad has grown up. During the implementation of clinical comprehensive evaluation of Chinese patent medicine, it is necessary to clarify the evaluation perspective, define the evaluation scope, and determine the evaluation domains.
ObjectiveTo investigate the relation between mammographic density (MD) and the efficacy of neoadjuvant chemotherapy (NACT) for patients with breast cancer. MethodsThe clinicopathologic data of patients diagnosed with breast cancer in the Affiliated Hospital of Southwest Medical University from January 2019 to December 2021 and met the inclusion and exclusion criteria of this study were collected. According to the 5th edition of the Breast Imaging-Reporting and Data System, the MD was classified into 4 categories: a, b, c, and d. Based on the pathological evaluation systems of Miller-Payne and Residual Cancer Burden, the new and improved pathological criteria was structured including the residual cancer cell and lymph node statuses to evaluate the pathological changes of breast cancer after NACT. After adjusting the factors affecting MD, the original model (only including MD categories as independent variables), the minimum adjustment model (adding age, body mass index, and menopausal status as independent variables), and the fully adjusted model (further including estrogen receptor, progesterone receptor, human epidermal growth factor receptor 2, Ki-67, axillary lymph node status at the initial diagnosis, and NACT regimen) were used to analyze the relation between MD and NACT effect. In the 3 models, the MD category a was used as the reference. ResultsA total of 287 patients with breast cancer were enrolled in this study. Thirty-eight, 76, 114, and 59 of whom with MD category a, b, c, and d respectively, and 14, 74, 117, and 82 of whom with grade L1, L2, L3, and L4 of NACT effect respectively. No matter in integrated patients or premenopausal patients, the results of the fully adjusted model showed that, the regression coefficient of MD classification was negative, and with the increase of MD classification, the odds ratio was <1 and showed a decreasing trend. ConclusionsFrom the results of this study, the increase of MD classification may have a negative impact on the effect of NACT. Namely, effect of NACT is poor in integrated patients or premenopausal patients of whom with higher MD. MD can be used as a predictor of NACT effect, so as to guide doctors in the selection and individual management of neoadjuvant therapy, and improve the prognosis of patients with breast cancer.
