ABSTRACTIn this article I explore, for the first time, the relationship between Sowa Rigpa (Tibetan medicine) and global health, tracing “the global” in ethical discourses and pharmaceutical innovation practices of Tibetan medical practitioners. I argue that Sowa Rigpa’s engagement with the world and its global health activities outside China can be understood as a form of “humanitarianism from below,” while its industrialization in China aligns with global health in different ways. In providing new insights into recent developments of Sowa Rigpa, I aim to decenter the notion of humanitarianism and contribute to a broader understanding of global health. 相似文献

目的 解析真实世界中乳腺恶性肿瘤患者的人群特征、诊断特征、中西医用药特征,为乳腺癌的临床防治提供参考。方法 采集2002年2月至2015年5月全国60家三级甲等医 院信息系统(Hospital Information System,HIS)中,出院诊断为“乳腺癌”的患者用药信息,采用SAS9.3统计软件,对人口学信息、诊断信息、医嘱用药信息等进行描述性分析。结果 39798例乳腺癌患者,平均年龄(50.93者,平均年龄)岁;多以门诊入院,入院病情以“一般”为主;合并疾病主要为高血压,骨肿瘤,联用西药以抑制肿瘤细胞增殖、治疗并发症、缓解放化疗不良反应为主;中医辨证以痰瘀互结证,气阴两虚证,肝气淤滞证,脾气亏虚证型最为常见,临床清热解毒剂、益气扶正剂,活血化瘀剂应用较多。结论 乳腺癌中西医结合治疗,联用药物广泛,临床治疗基本符合临床指南。 相似文献

目的探讨针刺京骨穴联合推拿治疗背肌筋膜炎的临床疗效。方法将2016年10月—2018年10月收治的背肌筋膜炎患者86例纳入研究,采用随机数字表法分组。对照组43例予以推拿治疗,观察组43例予以针刺京骨穴联合推拿治疗。比较2组患者的治疗总有效率、VAS评分及Oswestry功能障碍指数、痊愈所用时间。结果观察组治疗总有效率为95.3%,而对照组仅为81.4%,差异有统计学意义(P<0.05);2组治疗后VAS评分、Oswestry功能障碍指数均有下降,观察组上述指标低于对照组,差异有统计学意义(P<0.05);观察组痊愈所用时间短于对照组,差异有统计学意义(P<0.05)。结论针刺京骨穴联合推拿治疗背肌筋膜炎的临床疗效突出,可缓解背部疼痛、恢复功能活动,并缩短了愈合时间,提高了生活质量,值得一定的临床推广。 相似文献

BackgroundEmergency Medicine/Critical Care Medicine (EM/CCM) trainees may obtain board certification through Internal Medicine (American Board of Internal Medicine [ABIM]), Surgery (American Board of Surgery [ABS]), and Anesthesiology (American Board of Anesthesiology [ABA]). However, EM/CCM trainees experience challenges, including: 1) additional training requirements and 2) an unwillingness to accept EM graduates by many programs.ObjectivesWe sought to: 1) compare EM/CCM knowledge acquisition to medicine (Internal Medicine [IM]/CCM), surgery (surgical critical care [SCC]), and anesthesiology (anesthesiology critical care medicine [ACCM]) Fellows at the local and national level using the Multidisciplinary Critical Care Knowledge Assessment Program (MCCKAP) in-service examination as an objective measure; and 2) compare American Board of Medical Specialties (ABMS) pass rates for EM/CCM.MethodsSingle-center retrospective analysis comparing scores obtained by EM/CCM on the MCCKAP examination with SCC and ACCM over a 10-year period. Scores are presented as means with standard deviations. We performed similar analysis on ABMS examination pass rates.ResultsThere were 117 MCCKAP scores (37 EM/CCM; 80 SCC and ACCM) evaluated. EM/CCM mean score 562.4 (SD 67.4); SCC and ACCM mean score 505.3, (SD 87.5) at the institutional level (p < 0.001). Similarly, EM/CCM scored higher than the national mean (562.4, SD 67.4 vs. 500 SD 100, p < 0.001). Nationally, ABIM-CCM board certification rate was 91.2% for 137 EM/CCM, compared with 93.2% for IM/CCM (p = 0.22); 28 EM/CCM have obtained ABA-CCM board certification with rates similar to ACCM (90.4 vs. 89.3%; p = 0.85).ConclusionsEM/CCM Fellows demonstrate successful knowledge acquisition both locally and at a national level. EM/CCM achieve ABMS pass rates similar to other CCM trainees. The current arbitrary additional training requirements placed on EM/CCM should be removed. 相似文献

A major incident is one that causes casualties on a scale beyond the usual capabilities of the emergency and healthcare services usual ability to manage. Major incident planning and rehearsal is vital to ensuring an appropriate response. Delivery of a major incident response requires command and co-ordination within and between emergency services, hospitals and specialist charitable organizations. Casualty management will require the set up of major incident infrastructure on scene to effectively extricate, triage, treat and transport casualties to appropriate facilities. There is a role for specialist doctors within the pre-hospital phase of managing a major incident, either within the ambulance command structure or operationally. Debrief and reviewing previous major incidents may identify individual, local and systemic factors that could be altered to improve the response to a future incident. 相似文献

Background
Herbal medicine has been widely utilized by pregnant women despite the limited available evidence regarding the safety and efficacy of that practice. The current available studies, from different countries, estimated that the use of herbal medicine during pregnancy range from 7% up to 96%. The aim of this study is to determine the prevalence, attitude, source of information, and reasoning behind the use of herbal medicine among pregnant women in Saudia Arabia.Methods
A cross-sectional study conducted using a convenience sample including pregnant women who visited the obstetric clinics at King Abdulaziz Medical City in Riyadh, Saudi Arabia. A survey was administered in order to evaluate the prevalence and perception toward herbal medicine use among pregnant women in Saudi Arabia.Results
A total of 297 pregnant women completed the survey. The results showed that 56% of the respondents have used some type of herbal medicine during their pregnancy. Olive oil was utilized in 26% of the respondents followed by cumin 20% and garlic 15%. In addition, 37% of the respondents used herbal medicine by their own initiative, while 33% and 12% used herbal medicine based on recommendations from their families and friends, respectively. Furthermore, 19% of the respondents reported a positive attitude toward herbal medicine use during pregnancy. In addition, the percentage of women with positive attitude was marginally higher among respondents with lower educational level.Conclusion
The prevalence of using herbal medicine is considerably high among pregnant women in Saudi Arabia. Unfortunately, the majority of the users relied on informal sources to use herbal medicine during pregnancy. 相似文献58.

On February 20, 2020, a man living in the north of Italy was admitted to the emergency room with an atypical pneumonia that later proved to be COVID-19. This was the trigger of one of the most serious clusters of COVID-19 in the world, outside of China. Despite aggressive restraint and inhibition efforts, COVID-19 continues to increase, and the total number of infected patients in Italy is growing daily. After 6 weeks, the total number of patients reached 128,948 cases (April 5, 2020), with the higher case-fatality rate (15,887 deaths) dominated by old and very old patients.This sudden health emergency severely challenged the Italian Health System, in particular acute care hospitals and intensive care units. In 1 hospital, geriatric observation units were created, the experience of which can be extremely useful for European countries, the United States, and all countries that in the coming days will face a similar situation. 相似文献
