    心房颤动(AF)导管消融成功率尤其是持续性房颤,保持次优。十多年来,肺静脉隔离一直是房颤导管消融的基石。虽然对大多数患者来说是成功的,仅肺静脉隔离对于相当少的人来说仍然是不够的.令人沮丧的是,多项临床试验测试了多种额外的消融方法,结果喜忧参半,在所有患者中,目前的策略没有改善除肺静脉隔离外的房颤结局.然而,这一大组数据可用于提取有关房颤机制和房颤综合征多样性的重要见解.机械上,心律失常发生的一般模型提示需要单独评估触发因素的工具,司机,和个别患者的底物。一个关键目标是识别那些对肺静脉隔离没有反应的人,新的表型方法,可能包括作图以识别替代驱动因素或关键底物。这个,反过来,可以允许基于表型的实施,有针对性的方法可以将患者分为可能或不可能对导管消融有反应的组,药物治疗,和风险因素修改计划。一个主要目标是预测那些额外的经验消融的个体,虽然可行,可能是徒劳的或导致心房疤痕或致心律失常。这项工作试图整合成功和失败的导管消融试验的关键经验。以及AF的模型,建议未来房颤治疗的范例。
    Success rates for catheter ablation of atrial fibrillation (AF), particularly persistent AF, remain suboptimal. Pulmonary vein isolation has been the cornerstone for catheter ablation of AF for over a decade. While successful for most patients, pulmonary vein isolation alone is still insufficient for a substantial minority. Frustratingly, multiple clinical trials testing a diverse array of additional ablation approaches have led to mixed results, with no current strategy that improves AF outcomes beyond pulmonary vein isolation in all patients. Nevertheless, this large collection of data could be used to extract important insights regarding AF mechanisms and the diversity of the AF syndrome. Mechanistically, the general model for arrhythmogenesis prompts the need for tools to individually assess triggers, drivers, and substrates in individual patients. A key goal is to identify those who will not respond to pulmonary vein isolation, with novel approaches to phenotyping that may include mapping to identify alternative drivers or critical substrates. This, in turn, can allow for the implementation of phenotype-based, targeted approaches that may categorize patients into groups who would or would not be likely to respond to catheter ablation, pharmacological therapy, and risk factor modification programs. One major goal is to predict individuals in whom additional empirical ablation, while feasible, may be futile or lead to atrial scarring or proarrhythmia. This work attempts to integrate key lessons from successful and failed trials of catheter ablation, as well as models of AF, to suggest future paradigms for AF treatment.

    常规方法,如病史,神经心理学测试,脑脊液检查,在当前的临床环境中,磁共振成像被广泛用于诊断病例,但在对阿尔茨海默病(AD)分期进行分类方面受到限制。AD患者表现出视觉感知缺陷,这可能是根据视觉范式评估疾病严重程度的潜在目标。然而,由于感知对象的形式不一致,当前视觉处理范式的缺陷往往导致结果不一致,缺乏敏感性和特异性。
    我们基于视觉感知的全局优先拓扑方法开发了两种范式,这避免了由于传统范式中感知对象的不一致形式而导致的不一致结果以及缺乏敏感性和特异性,从感知组织(实验1)和视觉工作记忆(VWM)(实验2)中描述一种独特的检测策略。
    除了各组之间反应时间(RTs)的显着差异外,由于相似性检验中全局和局部数字的一致性,当AD受试者识别小数字时发现显着差异。在相似性测试中,与健康老年人(HE)相比,在AD和轻度认知障碍(MCI)组中可以识别出整体和局部特征之间的RTs差异(实验1)。AD患者的记忆能力明显低于MCI组。MCI和HE组均观察到拓扑干扰效果。而MCI患者在非拓扑和拓扑变化方面的差异趋势可能大于HE(实验2)。
    我们的范式提供了一种新的策略,这可以帮助临床严重程度分期,并将视觉感知的拓扑方法与AD的病理生理过程联系起来。
    UNASSIGNED: Conventional methods like patient history, neuropsychological testing, cerebrospinal fluid examination, and magnetic resonance imaging are widely used to diagnose cases in the current clinical setting but are limited in classifying Alzheimer\'s disease (AD) stages. Patients with AD exhibit visual perception deficits, which may be a potential target to assess the severity of the disease according to visual paradigms. However, owing to the inconsistent forms of perceived objects, the defects of current visual processing paradigms often lead to inconsistent results and a lack of sensitivity and specificity.
    UNASSIGNED: We develop two paradigms based on global-first topological approach of visual perception, which avoids inconsistent results and lack of sensitivity and specificity owing to the inconsistent forms of perceived objects in traditional paradigms, delineate a unique detection strategy from perception organization (Experiment 1) and visual working memory (VWM) (Experiment 2).
    UNASSIGNED: Except for the significant differences of the reaction times (RTs) between groups, significant differences were found when AD subjects recognize small figures due to the consistency of global and local figures in similarity test. The difference of RTs between recognizing global and local figures can be recognized in AD and mild cognitive impairment (MCI) group compared to healthy elderly (HE) in similarity test (Experiment 1). The memory capacity of AD patients was significantly lower than MCI group. Topological interference effect was observed in MCI and HE group, whereas MCI patients may have a greater difference trend in non-topological and topological changes than HE (Experiment 2).
    UNASSIGNED: Our paradigms provide a new strategy, which can assist clinical severity staging and linking topological approach of visual perception with pathophysiological processes in AD.

    这项研究的目的是使用科学哲学的历史方法和核心原理来解释为什么在乳酸性酸中毒构造的发展中犯了错误。在更广泛的范围内,这项研究解释了什么是科学,为什么一些科学家尽管有良好的意图,经常弄错,以及为什么需要这么长时间(几十年)来纠正这些错误。科学是一种人类行为,包括基于正确应用先验知识来识别问题,开发一种最佳解决或测试问题的方法,完成这些方法以获得结果,然后对结果进行正确的解释。如果这些步骤正确完成,则结果可能正确的可能性会增加(不能保证)。托马斯·库恩提出,你可以从科学的表现来理解什么是科学,从他的论文中,他揭示了一种功能失调的科学形式,他称之为“正常”(由于其存在的优势)。相反,卡尔·波普尔坚持认为,“正常”科学的实践揭示了许多缺陷,这些缺陷偏离了科学的基本原理,科学。总的来说,证据表明,在运动医学和健康科学中,和所有学科一样,科学中的错误比你想象的更频繁。迫切需要改进我们如何教育和培训科学家,以防止对“正常”科学的追求及其对人类的危害。
    The purpose of this research was to use a historical method and core principles from scientific philosophy to explain why mistakes were made in the development of the lactic acidosis construct. On a broader scope, this research explains what science is, why some scientists despite good intention, often get it wrong, and why it takes so long (decades) to correct these errors. Science is a human behaviour that consists of the identification of a problem based on the correct application of prior knowledge, the development of a method to best resolve or test the problem, completion of these methods to acquire results, and then a correct interpretation of the results. If these steps are done correctly there is an increased probability (no guarantee) that the outcome is likely to be correct. Thomas Kuhn proposed that you can understand what science is from how it has been performed, and from his essays he revealed a very dysfunctional form of science that he called \'normal\' (due the preponderance of its presence) science. Conversely, Karl Popper was adamant that the practice of \'normal\' science revealed numerous flaws that deviate from fundamental principles that makes science, science. Collectively, the evidence reveals that within the sports medicine and health sciences, as with all disciplines, errors in science are more frequent than you might expect. There is an urgent need to improve how we educate and train scientists to prevent the pursuit of \'normal\' science and the harm it imparts on humanity.

    The field of plastic surgery is continuously evolving, with faster-emerging technologies and therapeutic approaches, leading to the necessity of establishing novel protocols and solving models. Surgical decision-making in reconstructive surgery is significantly impacted by various factors, including the etiopathology of the defect, the need to restore form and function, the patient\'s characteristics, compliance and expectations, and the surgeon\'s expertise. A broad surgical armamentarium is currently available, comprising well-established surgical procedures, as well as emerging techniques and technologies. Reconstructive surgery paradigms guide therapeutic strategies in order to reduce morbidity, mortality and risks while maximizing safety, patient satisfaction and properly restoring form and function. The paradigms provide researchers with formulation and solving models for each unique problem, assembling complex entities composed of theoretical, practical, methodological and instrumental elements.

    背景:在过去的十年中,血友病的管理取得了转化性进展,取得了更好的结果。然而,对其评估和报告的详细和严格的审查显示了许多方面的差距。这些都在这篇综述中进行了讨论。
    方法:回顾了血友病管理不同方面的相关文献,以找出需要解决的差距。这些包括血友病的检测和诊断,关节出血的记录和报告,其在临床试验和实践中的管理和报告方法,个性化护理的各个方面,以及获得治疗产品以及全面护理的需求和组织。
    结果:在过去的25年中,目前的诊断方法使已确定的血友病(PWH)人数增加了一倍以上,但仍仅占预期人数的约30%。关节出血是判断疾病严重程度和治疗效果的首要指标,但是记录和报告的方式缺乏一致性和标准化。其继续用作维持稳态因子水平或>5%的等效性的现代治疗的功效量度将缺乏敏感性。急性关节积血的治疗主要集中在止血和疼痛控制上,忽视炎症在关节损伤中的作用。严重血友病的表型异质性已经认识到基于止血的临床和实验室变化,但没有对关节中血液的局部反应的差异。在组织层面,当检出率为〜100%时,IU/人均提供了获得治疗产品的相关衡量标准,但当检出率非常低时,IU/人均低。血友病的现代疗法非常有效,几乎没有出血,综合护理团队的概念将需要修改。
    结论:随着血友病护理的进步,需要深入研究其管理各个方面的细节,以确保一致性和当代相关性。
    BACKGROUND: Transformational advances have occurred in the management of haemophilia in the last decade leading to much better outcomes. However, a detailed and critical examination of its assessment and reporting show gaps in many aspects. These are discussed in this review.
    METHODS: The relevant literature related to different aspects of management of haemophilia was reviewed to identify gaps which need to be addressed. These include detection and diagnosis of haemophilia, documentation and reporting of joint bleeding, its management and methods of reporting in clinical trials and practice, aspects of personalizing care as well as access to therapeutic products and the need for and organization of comprehensive care.
    RESULTS: Current diagnostic approaches have more than doubled the identified number of persons with haemophilia (PWH) over the last 25 years but still constitute only ∼30% of the expected number. Joint bleeding is the primary indicator of disease severity and treatment efficacy, but there is lack of consistency and standardization in the way it is recorded and reported. Its continued use as an efficacy measure of modern treatments which maintain steady state factor levels or equivalence of >5% will lack sensitivity. The treatment of acute haemarthrosis has focussed on haemostasis and pain control, ignoring the role of inflammation in joint damage. Phenotypic heterogeneity of severe haemophilia has recognized clinical and laboratory variations based on haemostasis but not differences in local response to blood in the joint. At the organizational level, IU/capita provides a relevant measure of access to therapeutic products when the detection rate is ∼100% but is fallaciously low when detection rates are very low. With highly effective modern therapies for haemophilia and nearly no bleeding, the concept of comprehensive care team will need modifications.
    CONCLUSIONS: As haemophilia care advances, a deeper dive is needed into the details of various aspects its management to ensure consistency and contemporary relevance.

    In a thoughtful commentary in this journal a decade ago, Michael Rutter reviewed 25 years of progress in the field before concluding that developmental psychopathology (DP) initiated a paradigm shift in clinical science. This deduction requires that DP itself be a paradigm. According to Thomas Kuhn, canonical paradigms in the physical sciences serve unifying functions by consolidating scientists\' thinking and scholarship around single, closed sets of discipline-defining epistemological assumptions and methods. Paradigm shifts replace these assumptions and methods with a new field-defining framework. In contrast, the social sciences are multiparadigmatic, with thinking and scholarship unified locally around open sets of epistemological assumptions and methods with varying degrees of inter-, intra-, and subdisciplinary reach. DP challenges few if any of these local paradigms. Instead, DP serves an essential pluralizing function, and is therefore better construed as a metaparadigm. Seen in this way, DP holds tremendous untapped potential to move the field from zero-sum thinking and scholarship to positive-sum science and epistemological pluralism. This integrative vision, which furthers Dante Cicchetti\'s legacy of interdisciplinarity, requires broad commitment among scientists to reject zero-sum scholarship in which portending theories, useful principles, and effective interventions are jettisoned based on confirmation bias, errors in logic, and ideology.

    随着我们进入联合国生态系统恢复十年(2021-2030),并解决大规模保护和恢复生态系统及其生态功能的迫切需要,野化已成为众人瞩目的焦点。因此,对这门学科的兴趣越来越大,近年来发表了大量的概念性科学论文。越来越多的热情导致科学界对生态恢复和野化之间的差异进行讨论和辩论。本次审查的主要目标是比较和澄清每个领域的立场。我们的结果表明,尽管存在一些差异(例如自上而下与自下而上以及功能与分类学方法),尤其是具有不同的目标-恢复定义的历史确定的目标生态系统与恢复通常没有目标终点的自然过程-生态恢复和野化具有共同的范围:人为退化后的生态系统恢复。随着各个领域的发展,生态恢复和野化的目标不断扩大。然而,目前尚不清楚生态恢复是否正在朝着野化方向发展,反之亦然。我们强调生态恢复和野化在时间和空间上的互补性。最后,我们认为,协调这两个自然保护领域,以确保互补性可以创造一个协同作用,以实现他们的共同范围。
    As we enter the UN Decade on Ecosystem Restoration (2021-2030) and address the urgent need to protect and restore ecosystems and their ecological functions at large scales, rewilding has been brought into the limelight. Interest in this discipline is thus increasing, with a large number of conceptual scientific papers published in recent years. Increasing enthusiasm has led to discussions and debates in the scientific community about the differences between ecological restoration and rewilding. The main goal of this review is to compare and clarify the position of each field. Our results show that despite some differences (e.g. top-down versus bottom-up and functional versus taxonomic approaches) and notably with distinct goals - recovery of a defined historically determined target ecosystem versus recovery of natural processes with often no target endpoint - ecological restoration and rewilding have a common scope: the recovery of ecosystems following anthropogenic degradation. The goals of ecological restoration and rewilding have expanded with the progress of each field. However, it is unclear whether there is a paradigm shift with ecological restoration moving towards rewilding or vice versa. We underline the complementarity in time and in space of ecological restoration and rewilding. To conclude, we argue that reconciliation of these two fields of nature conservation to ensure complementarity could create a synergy to achieve their common scope.
