    每年在美国医疗保健领域因欺诈和滥用而损失高达数千亿美元,使其成为系统的重大负担。本研究调查了脊柱外科医疗保健欺诈的一个具体实例,其中一家医疗器械公司最终支付了7500万美元来解决违反“虚假索赔法”的问题。我们回顾了椎体后凸成形术的手术背景,以及它的账单和报销细节。我们还探讨了美国司法部提出的官方法律投诉,讲述了21世纪脊柱外科最重要的医疗创新之一如何变成了广泛的欺诈性营销计划。在序列中,我们对这一丑闻进行了详细的根本原因分析,并提出了一些可以采取的积极措施,以避免此类不幸事件。最终,这一历史性的医疗保健丑闻对外科医生来说是一个宝贵的教训,卫生保健管理员,医疗器械公司,以及政策制定者关于错位的激励措施和随后的不道德做法如何将医疗创新转变为不幸的欺诈和欺骗故事。
    Up to hundreds of billions of dollars are annually lost to fraud and abuse in the US health care, making it a significant burden on the system. This study investigates a specific instance of health care fraud in spine surgery, in which a medical device company ended up paying $75 million to settle violations of the False Claims Act. We review the surgical background regarding the kyphoplasty procedure, as well as its billing and reimbursement details. We also explore the official legal complaint brought by the US Department of Justice to tell the story of how one of the most significant medical innovations in spine surgery in the 21st century turned into a widespread fraudulent marketing scheme. In the sequence, we provide a detailed root cause analysis of this scandal and propose some proactive measures that can be taken to avoid such type of unfortunate events. Ultimately, this historical health care scandal constitutes a valuable lesson to surgeons, health care administrators, medical device companies, and policymakers on how misaligned incentives and subsequent unscrupulous practices can transform a medical innovation into an unfortunate tale of fraud and deceit.

    征求临床实验室人员对美国食品和药物管理局(FDA)提出的规范实验室开发测试(LDTs)作为医疗设备的可量化反馈。
    开发了十项问卷,并提交给ARUP实验室的临床实验室客户,犹他大学病理学系的国家非营利性临床实验室。
    在503名临床实验室受访者中,只有41人(8%)支持FDA提议的规则。67%的受访者在执行LDT的实验室工作,因此被问及有关拟议规则的其他问题。84%的受访者认为拟议的规则会对他们的实验室产生负面影响。而只有3%的人认为他们有足够的财力来支付FDA的使用费。61%的受访者预计,如果拟议的规则颁布,将从他们的实验室菜单中删除测试,另有33%的人表示他们还不知道。只有11%的受访者认为,如果最终规则颁布,他们将寻求FDA提交所有现有的LDT。绝大多数受访者(>80%)对拟议规则对患者获得基本检测的影响表示“非常关注”或“非常关注”,遵守财政和人力资源,创新,FDA实施该规则的能力,以及发送成本和测试价格。
    接受调查的大多数临床实验室人员不支持FDA关于LDT的拟议规则,并报告说如果颁布该规则,则没有足够的资源来遵守该规则。
    UNASSIGNED: To solicit quantifiable feedback from clinical laboratorians on the U.S. Food and Drug Administration (FDA) proposed rule to regulate laboratory-developed tests (LDTs) as medical devices.
    UNASSIGNED: A ten-item questionnaire was developed and submitted to clinical laboratory customers of ARUP Laboratories, a national nonprofit clinical laboratory of the University of Utah Department of Pathology.
    UNASSIGNED: Of 503 clinical laboratory respondents, only 41 (8 %) support the FDA\'s proposed rule. 67 % of respondents work in laboratories that perform LDTs and were therefore asked additional questions regarding the proposed rule. 84 % of these respondents believe that the proposed rule will negatively impact their laboratories, while only 3 % believe that they have the financial resources to pay for FDA user fees. 61 % of respondents anticipate removing tests from their laboratory menus if the proposed rule is enacted, while an additional 33 % indicated that they do not yet know. Only 11 % of respondents believe that they would pursue FDA submissions for all of their existing LDTs if the final rule is enacted. The vast majority of respondents (>80 %) were either \'extremely concerned\' or \'very concerned\' about the impact of the proposed rule on patient access to essential testing, financial and personnel resources to comply, innovation, the FDA\'s ability to implement the rule, and send-out costs and test prices.
    UNASSIGNED: The majority of clinical laboratorians surveyed do not support the FDA\'s proposed rule on LDTs and report having insufficient resources to comply with the rule if it is enacted.

    三尖瓣返流(TR)是常见的,并且与显著的死亡率和发病率相关。由于医疗和手术治疗的有效性和安全性有限,对于这种疾病的治疗存在显著的未满足的需求。因此,有一个不断增长的市场经皮设备,提供更安全,侵入性较小,和更有效的治疗选择在这个病人群体。2024年2月13日,美国食品和药物管理局(FDA)召开了循环系统设备小组会议,讨论了TriClip经导管瓣膜修复系统(Abbott,圣克拉拉,CA,美国)。讨论了几个要点,包括TRILUMINATEPivotal研究的最新数据,使用以患者为导向的结果进行设备批准,以及批准突破性设备时有关培训要求和推广计划的讨论。在这份手稿中,我们总结了申办方和FDA提交的数据,并描述了会议期间的审议和讨论情况.
    Tricuspid regurgitation (TR) is common and associated with significant mortality and morbidity. Because the effectiveness and safety of medical and surgical treatments are limited, there is a significant unmet need for the treatment of this disease. Therefore, there is a growing market for percutaneous devices that offer safer, less invasive, and more effective treatment options in this patient population. On February 13, 2024, the US Food and Drug Administration (FDA) convened a meeting of the Circulatory System Devices Panel to discuss the safety and effectiveness of the TriClip Transcatheter Valve Repair System (Abbott, Santa Clara, CA, USA). Several important points were discussed, including newly published data from the TRILUMINATE Pivotal study, the use of patient-oriented outcomes for device approval, and a discussion about training requirements and rollout plans when approving a breakthrough device. In this manuscript, we summarize the data presented by the sponsor and FDA and describe the deliberations and discussions during the meeting.

    局部作用皮肤病药物产品的生物等效性测定依赖于通过理化组成和结构比较评估产品一致性,比较活性成分在假定作用部位的浓度,或比较测试(将是通用的)和参考产品的临床表现。局部产品对皮肤疾病的作用可能被赋形剂的作用所混淆,并且还受到产品如何与皮肤相互作用的固有变异性的影响。包括蒸发等热力学因素,铺展性,以及与当地环境如热量和光线以及皮肤水分的相互作用。
    Bioequivalence determinations for locally acting dermatology drug products rely on assessing product sameness thru physicochemical composition and structure comparison, comparing the concentration of the active ingredient at the putative site of action, or comparing the clinical performance of the test (would-be generic) and reference products. Topical product action on cutaneous disease may be confounded by the action of excipients and are also subject to the inherent variability of how product may interact with the skin, including thermodynamic factors such as evaporation, spreadability, and interaction with the local environment such as heat and light and skin moisture.

    同种异体细胞治疗产品的翻译,细胞库不仅需要制造最终的人类产品,而且在基于动物的类似细胞产品(ACP)的临床前评估期间也需要。这些细胞库需要在主细胞库(MCB)级别和工作细胞库(WCB)级别建立。由于细胞治疗产品的大部分开发都在学术中心,学术研究人员必须了解如何在学术环境中建立MCB和WCB。为了说明这个过程,以关节软骨为模型,开发了ACP的细胞库(第2代MCB,第5代WCB),以产生用于临床前评估的自组装新软骨(第7代构建体).估计细胞库系统能够为六个MCB中的每一个产生160,000至400,000个构建体。总的来说,ACP细胞库产生的构建体类似于预期的人类产品,这对于进行ACP的临床前评估以纳入FDA的研究新药申请至关重要。 .
    Toward the translation of allogeneic cell therapy products, cell banks are needed not only to manufacture the final human product but also during the preclinical evaluation of an animal-based analogous cellular product (ACP). These cell banks need to be established at both the master cell bank (MCB) level and the working cell bank (WCB) level. Inasmuch as most of the development of cell therapy products is at academic centers, it is imperative that academic researchers understand how to establish MCBs and WCBs within an academic environment. To illustrate this process, using articular cartilage as the model, a cell bank for an ACP was developed (MCBs at passage 2, WCBs at passage 5) to produce self-assembled neocartilage for preclinical evaluation (constructs at passage 7). The cell bank system is estimated to be able to produce between 160 000 and 400 000 constructs for each of the six MCBs. Overall, the ACP cell bank yielded constructs that are analogous to the intended human product, which is critical toward conducting preclinical evaluations of the ACP for inclusion in an Investigational New Drug application to the FDA.

    目标:面临医疗服务机构(HDO)在浏览美国食品和药物管理局(FDA)关于使用临床决策支持(CDS)软件的最终指南时面临的紧迫困境。
    方法:我们使用败血症作为案例研究,以强调美国6129家医院必须进行的患者安全和法规遵从性权衡。
    结果:脓毒症CDS仍然广泛,常规使用。没有被FDA批准为医疗设备的市售脓毒症CDS系统。由于监管合规问题,没有公开披露HDO关闭脓毒症CDS。并且没有公开披露FDA针对HDO的执法行动,该HDO使用未被清除为医疗设备的败血症CDS。
    结论:我们提出了多种政策干预措施,以缓解当前的紧张局势,使HDO能够利用人工智能来改善患者护理,同时解决FDA对产品安全的担忧。功效,和公平。
    OBJECTIVE: Surface the urgent dilemma that healthcare delivery organizations (HDOs) face navigating the US Food and Drug Administration (FDA) final guidance on the use of clinical decision support (CDS) software.
    METHODS: We use sepsis as a case study to highlight the patient safety and regulatory compliance tradeoffs that 6129 hospitals in the United States must navigate.
    RESULTS: Sepsis CDS remains in broad, routine use. There is no commercially available sepsis CDS system that is FDA cleared as a medical device. There is no public disclosure of an HDO turning off sepsis CDS due to regulatory compliance concerns. And there is no public disclosure of FDA enforcement action against an HDO for using sepsis CDS that is not cleared as a medical device.
    CONCLUSIONS: We present multiple policy interventions that would relieve the current tension to enable HDOs to utilize artificial intelligence to improve patient care while also addressing FDA concerns about product safety, efficacy, and equity.

    背景:药物警戒系统,如FDA不良事件报告系统(FAERS),是在临床试验中可能遗漏的不良事件监测建立的模型。我们旨在分析FAERS中的25种抗癫痫药物(ASM),以评估自杀和自我伤害行为的增加报告。
    方法:对25个ASM进行了分析:布立西坦,大麻二酚,卡马西平,Clobazam,氯硝西泮,地西泮,艾司利卡西平,felbamate,加巴喷丁,拉科沙胺,拉莫三嗪,左乙拉西坦,奥卡西平,Perampanel,苯巴比妥,苯妥英,普瑞巴林,普米酮,鲁非酰胺,stiripentol,Tiagabine,托吡酯,丙戊酸盐,vigabatrin,唑尼沙胺.从2004年1月1日至2020年12月31日,使用OpenVigil2.1工具收集了“自杀和自我伤害行为”的报告,指示为“癫痫”。相对报告比率,比例报告比率,使用所有其他癫痫患者的药物报告作为对照,计算报告比值比.
    结果:显著的相对运行比率,观察到地西泮的ROR(大于1,p<0.05)(2.909),普瑞巴林(2.739),布立西坦(2.462),加巴喷丁(2.185),氯硝西泮(1.649),唑尼沙胺(1.462),拉科沙胺(1.333),和左乙拉西坦(1.286)。
    结论:在本研究中分析的25个ASM中,4(16%)被确定与可能的真实不良事件有关。这些药物包括地西泮,布立西坦,加巴霉素,还有普瑞巴林.尽管FAERS数据库存在一些限制,在使用多个ASM的情况下,必须密切监测患者合并症是否增加自杀风险.
    BACKGROUND: Pharmacovigilance systems such as the FDA Adverse Event Reporting System (FAERS), are established models for adverse event surveillance that may have been missed during clinical trials. We aimed to analyze twenty-five anti-seizure medications (ASMs) in FAERS to assess for increased reporting of suicidal and self-injurious behavior.
    METHODS: Twenty-five ASMs were analyzed: brivaracetam, cannabidiol, carbamazepine, clobazam, clonazepam, diazepam, eslicarbazepine, felbamate, gabapentin, lacosamide, lamotrigine, levetiracetam, oxcarbazepine, perampanel, phenobarbital, phenytoin, pregabalin, primidone, rufinamide, stiripentol, tiagabine, topiramate, valproate, vigabatrin, zonisamide. Reports of \"suicidal and self-injurious behavior\" were collected from January 1, 2004, to December 31, 2020, using OpenVigil 2.1 tool with indication as \"Epilepsy\". Relative reporting ratio, proportional reporting ratio, and reporting odds ratio were calculated utilizing all other drug reports for epilepsy patients as a control.
    RESULTS: Significant relative operating ratio, ROR (greater than 1, p<0.05) were observed for diazepam (2.909), pregabalin (2.739), brivaracetam (2.462), gabapentin (2.185), clonazepam (1.649), zonisamide (1.462), lacosamide (1.333), and levetiracetam (1.286).
    CONCLUSIONS: Of the 25 ASMs that were analyzed in this study, 4 (16%) were identified to have been linked with a likely true adverse event. These drugs included diazepam, brivaracetam, gabapenetin, and pregabalin. Although several limitations are present with the FAERS database, it is imperative to closely monitor patient comorbidities for increased risk of suicidality with the use of several ASMs.
