The current Coronavirus disease (Covid-19) pandemic has spread to about 220 countries of the world and has resulted in a significant number of deaths globally. Infections are still on the rise, and the impact on the global death rate could be devastating. There are fears over the likely impact of a large number of deaths on body sourcing and handling of cadavers for teaching and research. Historically, epidemics come with several challenges and have often led to some level of negligence of ethical practices and health and safety regulations associated with body sourcing and handling. The authors highlighted some emerging problems in this article, focusing on Africa and Nigeria in particular. These problems include a higher risk of coronavirus exposure for body handlers, shortage of cadavers for teaching and learning, a lack of standard regulations leading to unethical body sourcing and handling, and a lack of monitoring and collaboration needed for a well-coordinated Covid-19 pandemic response strategy. If these issues are ignored, the previous gains made in anatomical ethical practices may be destroyed. Some useful recommendations for policymaking geared toward prevention or curtailing these emerging issues have been instilled in this article. 相似文献

As medical programs place increasing importance on competency-based training and surgical simulations for residents, anatomy laboratories, and body donation programs find themselves in a position of adapting to changing demands. To better assess the demand for “life-like” cadaveric specimens and evaluate the possible impacts that competency-based medical education could have upon the body donation program of McGill University, Canada, the authors tracked, over the course of the last 10 years, the number of soft-embalmed specimens, along with the number of teaching sessions and the residents enrolled in competency-based programs that are using cadaveric material. The results reveal that the number of soft-embalmed specimens used within residency training increased from 5 in 2009 to 35 in 2019, representing an increase from 6% of bodies to 36.5% of the total number of body donors embalmed in this institution. Correspondingly, the number of annual teaching sessions for residents increased from 19 in 2012 to 116 in 2019. These increases in teaching are correlated with increasing number of residents enrolled in competency-based programs over the last 3 years (Pearson r ranging from 0.9705 to 0.9903, and R2 ranging from 0.9418 to 0.9808). Those results suggest that the new skill-centered curricula which require residents to perform specific tasks within realistic settings, exhibit a growing demand for “life-like” cadaveric specimens. Institutions’ body donation programs must, therefore, adapt to those greater need for cadaveric specimens, which presents many challenges, ranging from the logistical to the ethical. 相似文献

为定量解释精英运动员重大比赛期间竞技状态显性和隐性影响因素间相互关系,运用文献资料、层次分析、模糊评价、数理统计等研究方法,基于国家队、省市运动队295名网球教练员、运动员调研数据,提出精英网球运动员重大比赛期间竞技状态影响因素假设命题,再引入SEM概念模型,对假设命题进行验证。结果表明:(1)竞技状态SEM概念模型中,体能训练整合度、技能训练整合度、心智训练整合度、适应度与保障度可作为隐性自变量,且均对竞技状态因变量有正向影响作用,H1、H2、H3、H4假设命题得到验证;(2)经SEM检验,依影响因素权重,精英网球运动员赛间竞技状态调控依次表现为技能训练整合度、心智训练整合度、体能训练整合度、适应度与保障度;(3)精英网球运动员的参赛表现,虽主要取决于竞技训练因子,但对于适应度与保障度中自然环境、社会环境和规程规则等非训练因子,同样不容忽视。 相似文献

从人力资本和社会资本的视角出发,以316名中国退役运动员为研究对象,探讨这2种资本对退役运动员收入的影响,结果显示:①中国退役运动员的收入差异较大,平均收入状况不容乐观;②在人力资本的各观测变量中,运动等级、受教育程度、身体健康状况和职业技能培训依次对退役运动员收入产生影响;③在社会资本各观测变量中,弱关系和网络异质性对退役运动员收入影响显著;④人力资本有助于退役运动员进入中等收入群体,社会资本有助于其进入高收入群体;⑤人力资本和社会资本对退役运动员的收入提升作用显著,且人力资本作用高于社会资本。基于此,从政府和个体层面提出提升退役运动员人力资本和社会资本的建议。 相似文献

The value that willed body donors provide to medical education is priceless. Their precious gift helps to teach anatomy, spatial relationships between morphological structures, anatomical variation, and professionalism to medical students in a way that plastic models, podcasts, and lectures cannot. They are also an important resource for medical research and a wide variety of postgraduate training opportunities. While many body donation programs throughout the world are nonprofit organizations, there are body donation companies in the United States that sell donors for-profit. These “body brokers” have accumulated large profits from this business. It is incongruous that others would profit from such a priceless, freely donated gift. To prevent this incongruity, it is proposed that the international anatomical community develop a normative culture (a bioethos) for body donation programs. This would involve the conscious and systematic development of ethical principles for the day-to-day policies and practices of institutions that collect and use human bodies. With the development of this bioethos, a cultural shift in how donors are treated would occur and, over time, this would become the normal practice. These principles would become fundamental and foundational for the procurement and use of priceless human tissues. 相似文献
