Background The US Food and Drug Administration and National Institutes of Health adopted the Exception from Informed Consent (EFIC) rule in 1996, permitting waiver of informed consent for certain emergency research, including trials funded by the federal government. The rule requires that prospective consent be sought when practicable from patients or their Legally Authorized Representative(s) (LAR), and for those enrolled without consent, the patient or their LAR must be given information and an opportunity to opt-out from continued participation at the earliest opportunity. We sought to census the trials conducted under the EFIC rule to facilitate research to better understand how the rule is being used.
美国食品和药物管理局和国家卫生研究院于1996年采用了知情同意例外(EFIC)规则,允许在某些紧急研究中放弃知情同意,包括联邦政府资助的试验。该规则规定,在切实可行的情况下,必须征求患者或其合法授权代表(LAR)的预期同意,对于未经同意而参加试验的患者或其合法授权代表,必须尽早向患者或其合法授权代表提供信息和选择退出继续参与的机会。我们试图对根据EFIC规则进行的试验进行普查,以促进研究,以便更好地了解该规则是如何使用的。

Posttraumatic Stress Disorder continues to be a highly stigmatized disease for the veteran population and stigma continues to be identified as the main deterrent in treatment seeking. Little attention has been paid to how the process of obtaining service-connected disability status can amplify veterans’ perceptions of being stigmatized. The following ethnographic study identified how combat veterans experienced stigma in processing through Veterans Affairs care and the effects of linking a Posttraumatic Stress Disorder diagnosis with disability compensation to perceived stigmas. Stigma was identified in two inter-related areas: 1) the structural level in the Veterans Affairs disability claims process and 2) the individual level in interactions with Veterans Affairs service providers. Results based on veterans’ narratives suggest that the disability claims process, requiring multiple repetitions of personal trauma, coupled with perceptions of institutional stigmas of malingering, created bureaugenic effects: a worsening of symptoms caused by bureaucratic protocols intended to help veterans. This process influenced first time treatment users of the Veterans Affairs by deterring treatment-seeking behavior but was not found to affect veterans who had already initiated treatment. Despite the experience of stigma and commodification of their suffering through disability and diagnostic screening, veterans still sought disability compensation. Veterans viewed this compensation as acknowledgment of their loss and validation of their sacrifice.
对于退伍军人来说,创伤后应激障碍仍然是一种高度污名化的疾病,污名化仍然被认为是寻求治疗的主要障碍。很少有人注意到,获得与服务有关的残疾身份的过程如何放大退伍军人被污名化的感觉。以下的民族志研究确定了退伍军人在退伍军人事务护理过程中如何经历耻辱,以及将创伤后应激障碍诊断与残疾补偿联系起来对感知耻辱的影响。在两个相互关联的领域中发现了耻辱感:1)退伍军人事务残疾索赔流程的结构层面;2)与退伍军人事务服务提供者互动的个人层面。基于退伍军人叙述的结果表明,残疾索赔过程需要多次重复个人创伤,再加上对装病的制度污名的认识,造成了官僚主义效应:旨在帮助退伍军人的官僚协议导致的症状恶化。这一过程通过阻止寻求治疗的行为来影响第一次接受治疗的退伍军人事务使用者,但未发现对已经开始治疗的退伍军人有影响。尽管退伍军人经历了耻辱,并通过残疾和诊断筛查将他们的痛苦商品化,但他们仍然寻求残疾赔偿。退伍军人认为这种补偿是对他们损失的承认和对他们牺牲的肯定。

Background Genetics and genomics research (GGR) is associated with several challenges including, but not limited to, implications of sharing research findings with participants and their family members, issues of confidentiality, determining appropriate methods for providing genetic or genomic information to individuals tested, and ownership of DNA obtained from the samples. Additionally, GGR holds significant potential risk for social and psychological harms.

Research ethics committees (RECs) and regulatory agencies assess whether the benefits of a proposed early-stage clinical trial outweigh the risks based on preclinical studies reported in investigator’s brochures (IBs). Recent studies have indicated that preclinical evidence presented in IBs is reported in a way that does not enable proper risk-benefit assessment. We interviewed different stakeholders (regulators, REC members, industry representatives, preclinical and clinical researchers, ethicists, and metaresearchers) about their views on measures to increase the completeness and robustness of preclinical evidence reporting in IBs.
研究伦理委员会(rec)和监管机构根据研究者手册(IBs)中报告的临床前研究,评估拟议的早期临床试验的益处是否大于风险。最近的研究表明,在IBs中提出的临床前证据的报告方式不能进行适当的风险-收益评估。我们采访了不同的利益相关者(监管机构、REC成员、行业代表、临床前和临床研究人员、伦理学家和元研究人员),了解他们对提高ib临床前证据报告的完整性和稳健性的措施的看法。

Stakeholders’ views on an institutional dashboard with metrics for responsible research 利益相关者对带有负责任研究指标的机构仪表板的看法

Background Concerns about research waste have fueled debate about incentivizing individual researchers and research institutions to conduct responsible research. Instead of looking at impact factors or grants, research institutions should be assessed based on indicators that pertain to responsible research. In this study, we showed stakeholders a proof-of-principle dashboard with quantitative metrics that visualized responsible research performance on a German University Medical Center (UMC) level. Our research question was: What are stakeholders’ views on a dashboard that displays the adoption of responsible research practices on a UMC-level?
对研究浪费的担忧引发了关于激励个人研究人员和研究机构进行负责任研究的辩论。对研究机构的评估不应着眼于影响因素或拨款,而应基于与负责任的研究有关的指标。在这项研究中,我们向利益相关者展示了一个原理证明仪表板,其中包含量化指标,可以在德国大学医学中心(UMC)层面上可视化负责任的研究绩效。我们的研究问题是:利益相关者对显示在umc级别上采用负责任的研究实践的仪表板的看法是什么?

Using numerical modeling and simulation to assess the ethical burden in clinical trials and how it relates to the proportion of responders in a trial sample 使用数值建模和模拟来评估临床试验中的伦理负担,以及它与试验样本中应答者比例的关系

In order to propose a more precise definition and explore how to reduce ethical losses in randomized controlled clinical trials (RCTs), we set out to identify trial participants who do not contribute to demonstrating that the treatment in the experimental arm is superior to that in the control arm. RCTs emerged mid-last century as the gold standard for assessing efficacy, becoming the cornerstone of the value of new therapies, yet their ethical grounds are a matter of debate. We introduce the concept of unnecessary participants in RCTs, the sum of non-informative participants and non-responders. The non-informative participants are considered not informative with respect to the efficacy measured in the trial in contrast to responders who carry all the information required to conclude on the treatment’s efficacy. The non-responders present the event whether or not they are treated with the experimental treatment. The unnecessary participants carry the burden of having to participate in a clinical trial without benefiting from it, which might include experiencing side effects. Thus, these unnecessary participants carry the ethical loss that is inherent to the RCT methodology. On the contrary, responders to the experimental treatment bear its entire efficacy in the RCT. Starting from the proportions observed in a real placebo-controlled trial from the literature, we carried out simulations of RCTs progressively increasing the proportion of responders up to 100%. We show that the number of unnecessary participants decreases steadily until the RCT’s ethical loss reaches a minimum. In parallel, the trial sample size decreases (presumably its cost as well), although the trial’s statistical power increases as shown by the increase of the chi-square comparing the event rates between the two arms. Thus, we expect that increasing the proportion of responders in RCTs would contribute to making them more ethically acceptable, with less false negative outcomes.
为了提出一个更精确的定义,并探讨如何减少随机对照临床试验(rct)中的伦理损失,我们开始确定那些不能证明实验组的治疗优于对照组的试验参与者。随机对照试验作为评估疗效的黄金标准出现在上世纪中期,成为新疗法价值的基石,但其伦理依据仍存在争议。我们在随机对照试验中引入了不必要参与者的概念,即无信息参与者和无反应者的总和。不提供信息的参与者被认为对试验中测量的疗效没有提供信息,而应答者则携带所有必要的信息来得出治疗疗效的结论。无反应者无论是否接受实验性治疗,都会出现该事件。这些不必要的参与者承担着必须参加临床试验而没有从中受益的负担,这可能包括经历副作用。因此,这些不必要的参与者承担了随机对照试验方法固有的伦理损失。相反,对实验性治疗的应答者在随机对照试验中承担其全部疗效。从文献中真正的安慰剂对照试验中观察到的比例开始,我们进行了随机对照试验的模拟,逐渐增加应答者的比例,直至100%。我们表明,不必要的参与者数量稳步减少,直到随机对照试验的伦理损失达到最小。与此同时,试验的样本量减少了(大概它的成本也减少了),尽管试验的统计能力增加了,这可以从比较两组事件发生率的卡方的增加中看出。因此,我们期望增加随机对照试验中应答者的比例将有助于使它们在道德上更可接受,减少假阴性结果。
