    生物库通过促进医学研究以及随后的研究成果的翻译和应用为后代提供了益处。涉及生物材料和相关数据的长期储存和研究需要适当实施道德和法律标准。一项关键原则包括承认知情同意是使生物材料和数据收集合法化的关键因素。此外,任何收集的材料和数据必须专门用于与参与者提供的明确同意相一致的研究框架.最后但并非最不重要的,数据隐私和安全在生物样本存储中至关重要。这篇综述阐明了生物样本在异基因造血细胞移植领域的机会和局限性。我们讨论了要求的实际执行,由协作生物库说明,血癌研究的合作研究平台。
    Biobanking provides benefit for future generations by facilitating medical research and subsequent translation and application of research findings. Long-term storage and research involving biological material and associated data necessitate the proper implementation of ethical and legal standards. A key principle includes recognizing informed consent as a crucial element for legitimizing the collection of biological material and data. Furthermore, any collected material and data must be employed exclusively for the research framework that aligns with the explicit consent provided by the participants. Last but not least, data privacy and security are essential in biobanking. This review elucidates chances and limitations of biobanking in the field of allogeneic hematopoietic cell transplantation. We discuss the practical implementation of the requirements, illustrated by the Collaborative Biobank, a collaborative research platform for research in blood cancer.

    背景:在接受先天性差异测试的幼儿中发现的相当大比例的致病性遗传变异与神经发育性精神障碍(NPD)有关。在这个不断壮大的群体中,基因诊断通常先于可诊断的发育问题的出现。这里,我们描述了DAGSY(遗传易感性青年发展评估),一个新的跨学科的“基因诊断第一”整合精神病的诊所,心理和遗传专业知识,并报告我们的首次观察和来自家庭和转诊临床医生的反馈。
    方法:我们检索了有关转诊来源和适应症的数据,2018年至2022年在DAGSY就诊的儿童的遗传和NPD诊断和建议。通过一项调查,我们获得了20个家庭和11名转诊临床医生的反馈。
    结果:159名儿童(平均年龄10.2岁,57.2%的男性)完成了跨学科(精神病学,心理学,遗传咨询)这一时期的DAGSY评估。其中,69.8%有致病性微缺失或微重复,21.5%的序列水平变异,4.4%的染色体异常,4.4%是未知意义的变异,具有新的致病性证据。四分之一的孩子之前没有NPD诊断,转诊DAGSY的动机仅在于他们的遗传脆弱性。评估后,76.7%的人至少接受了一次新的NPD诊断,最常见的智力残疾(24.5%),焦虑(20.7%),自闭症谱系障碍(18.9%)和特定学习障碍(16.4%)。回应我们调查的家庭和临床医生都表示满意,但也强调了一些潜在的改进领域。
    结论:DAGSY解决了被鉴定为具有增加NPD脆弱性的遗传变异的儿童的未满足的临床需求,并为该领域的研究提供了重要平台。DAGSY可以作为跨学科诊所整合儿童精神病学的典范,心理学和遗传学,满足这一新兴人群的临床和研究需求。
    BACKGROUND: A sizeable proportion of pathogenic genetic variants identified in young children tested for congenital differences are associated with neurodevelopmental psychiatric disorders (NPD). In this growing group, a genetic diagnosis often precedes the emergence of diagnosable developmental concerns. Here, we describe DAGSY (Developmental Assessment of Genetically Susceptible Youth), a novel interdisciplinary \'genetic-diagnosis-first\' clinic integrating psychiatric, psychological and genetic expertise, and report our first observations and feedback from families and referring clinicians.
    METHODS: We retrieved data on referral sources and indications, genetic and NPD diagnoses and recommendations for children seen at DAGSY between 2018 and 2022. Through a survey, we obtained feedback from twenty families and eleven referring clinicians.
    RESULTS: 159 children (mean age 10.2 years, 57.2% males) completed an interdisciplinary (psychiatry, psychology, genetic counselling) DAGSY assessment during this period. Of these, 69.8% had a pathogenic microdeletion or microduplication, 21.5% a sequence-level variant, 4.4% a chromosomal disorder, and 4.4% a variant of unknown significance with emerging evidence of pathogenicity. One in four children did not have a prior NPD diagnosis, and referral to DAGSY was motivated by their genetic vulnerability alone. Following assessment, 76.7% received at least one new NPD diagnosis, most frequently intellectual disability (24.5%), anxiety (20.7%), autism spectrum (18.9%) and specific learning (16.4%) disorder. Both families and clinicians responding to our survey expressed satisfaction, but also highlighted some areas for potential improvement.
    CONCLUSIONS: DAGSY addresses an unmet clinical need for children identified with genetic variants that confer increased vulnerability for NPD and provides a crucial platform for research in this area. DAGSY can serve as a model for interdisciplinary clinics integrating child psychiatry, psychology and genetics, addressing both clinical and research needs for this emerging population.

    全球挑战,比如气候变化,持续贫困,粮食不安全是复杂的问题。这些社会,环境,和经济挑战跨科学学科,社区,和地理,需要跨学科,南北解决方案。然而,流行的可持续发展科学对策是以西方为中心的。一些开创性的研究试图理解和参与不同的知识系统。这些包括非殖民化和土著方法,例如“两眼看到”,强调了利用西方和土著知识来更全面地了解世界的重要性,参与行动研究,这突出了让参与者参与研究过程和通过合作努力促进社会变革的重要性。然而,除了与传统土著知识的国内研究合作外,大多数南北研究忽视了以西方为中心的观点的作用或影响,因此未能认识和纳入不同的世界观和知识体系。这可能,在某种程度上,反映了将研究分类为学科孤岛的趋势,但更有可能的是无意的,然而普遍存在,认为西方科学是“客观和中立的”。“随着来自多个学科和地区的越来越多的学者专注于跨学科的南北研究,研究人员反思主导的研究方法和知识生产是至关重要的。研究可以共同构建,繁殖,或控制产生的知识形式——无论是有意的还是无意的。本文提出了一个组织框架来帮助研究人员导航,理解,并参与各种形式的知识进行南北研究。该框架借鉴了作者的跨学科研究和实证跨文化文献的实证观察。它包括三个上下文层面的影响,具有指导原则和随后的实际行动,研究人员可以用来驾驭南北研究中知识共建的复杂性。

    Global challenges, such as climate change, persistent poverty, and food insecurity are complex problems. These societal, environmental, and economic challenges cross scientific disciplines, communities, and geographies, requiring interdisciplinary, North-South solutions. Nevertheless, prevailing sustainability science responses are Western-centric. Some seminal studies have attempted to understand and engage with diverse knowledge systems. These include decolonial and Indigenous methodologies, such as \"Two-Eyed Seeing\", which emphasizes the importance of using both Western and Indigenous knowledge to gain a more comprehensive understanding of the world, and participatory action research, which highlights the importance of involving participants in the research process and promoting social change through collaborative effort. However, apart from in-country research collaborations with traditional Indigenous knowledge, most North-South studies overlook the role or influence of Western-centric views and therefore fail to recognize and incorporate diverse worldviews and knowledge systems. This may, in part, reflect the tendency to categorize research into disciplinary silos, but more likely is the unintentional, yet prevalent, view that Western science is \"objective and neutral.\" As more scholars from multiple disciplines and geographies focus on interdisciplinary North-South research, it is critical that researchers reflect on dominant research approaches and knowledge production. Studies can co-construct, reproduce, or control the forms of knowledge generated-whether intentional or unintentional. This paper presents an organizing framework to help researchers navigate, understand, and engage with diverse forms of knowledge in undertaking North-South research. The framework draws on empirical observations from the authors\' interdisciplinary research and from empirical cross-cultural literature. It comprises three contextual levels of influence, featuring guiding principles and subsequent practical actions researchers can use to navigate the complexities of knowledge co-construction in North-South research.

    定性研究方法越来越多地用于营养和营养学研究。人种学是一种未开发的方法,旨在探索给定环境中的人和文化的多样性,更好地了解决定他们选择和行为的影响。有人认为传统的人种学,也就是说,在参与社区中生活的方法,是一种过时的做法,植根于殖民主义,只有有手段的研究人员才能接触到,进行此类研究的联系和地位,通常是白色的,特权男性本文提出了对“拼凑人种学”的正式解释,研究是围绕研究人员现有的现代承诺进行的,从而使更多的研究人员在健康领域,营养和饮食实践受益于可以从社区发现的丰富数据。这篇综述提出了需要语用拼凑的民族志的概念,提出一个实施框架,提供研究人员,特别是在人类营养领域,营养学和健康,可访问性和部署有意义的以客户为中心的方法的手段。我们提出了实用的拼凑人种学作为一种在多种医疗机构中使用的现代方法,从而在定性研究的墙上增加了一个渐进的砖。
    Qualitative research methods are increasingly used in nutrition and dietetics research. Ethnography is an underexploited approach which seeks to explore the diversity of people and cultures in a given setting, providing a better understanding of the influences that determine their choices and behaviours. It is argued that traditional ethnography, that is, the methodology of living within participant communities, is a dated practice, with roots in colonialism, accessible to only researchers with the means, connections and status to conduct such research, typically white, privileged males. This paper proposes a formal interpretation of \'patchwork ethnography\', whereby research is carried out in situ around existing modern-day commitments of the researcher, thus enabling more researchers within health, nutrition and dietetic practice to benefit from the rich data that can be discovered from communities. This review proposes the concept that pragmatic patchwork ethnography is required, proposing a framework for implementation, providing researchers, particularly within the fields of human nutrition, dietetics and health, the accessibility and means to deploy a meaningful client-centric methodology. We present pragmatic patchwork ethnography as a modern method for use within multiple healthcare settings, thus adding a progressive brick in the wall of qualitative research.

    随着通过新的敏捷方法收集证据,健康研究正在迅速变化。这种演变至关重要,但必须在全球范围内公平,这样最贫穷的国家才不会失败。我们必须利用这一变化来更好地应对影响最贫困人口的疾病的日常负担,并将研究能力带到世界的每个角落,以便对新病原体做出快速和公平的反应。我们必须抓住这个机会,使研究变得更容易,更好,更公平。目前,太多的国家无法提供证据或将其转化为直接改变自己社区的健康结果。在如何生成和共享研究数据方面,采取行动和利用这一新兴变化至关重要。以便所有国家都可持续地从这一发展中获益。有一些积极的例子可以借鉴COVID-19,但我们现在需要采取行动。在这里,我们提出了一个倡议,以开发一个新的框架,可以指导研究人员设计和执行他们的研究。这个高度敏捷的系统将通过适应任何给定研究中的风险和复杂性来工作,在产生质量的同时,安全和道德的数据。
    Health research is rapidly changing with evidence being gathered through new agile methods. This evolution is critical but must be globally equitable so the poorest nations do not lose out. We must harness this change to better tackle the daily burden of diseases that affect the most impoverished populations and bring research capabilities to every corner of the world so that rapid and fair responses to new pathogen are possible; anywhere they appear. We must seize this opportunity to make research easier, better and more equitable. Currently too many nations are unable to generate the evidence or translate it to directly change health outcomes in their own communities. It is essential to act and harness this emerging change in how research data can be generated and shared, so that all nations sustainably gain from this development. There are positive examples to draw on from COVID-19, but we now need to act. Here we present an initiative to develop a new framework that can guide researchers in the design and execution of their studies. This highly agile system will work by adapting to risk and complexity in any given study, whilst generating quality, safe and ethical data.

    脑机接口(BCI)将大脑活动转换为数字命令,以便与物理世界进行交互。该技术在多个应用领域具有巨大潜力,从医疗应用到娱乐行业,并为认知神经科学的基础研究创造了新的条件。今天的BCI,然而,只提供用户当前心理状态的粗略在线分类,而更复杂的精神状态解码依赖于耗时的离线数据分析。本文通过利用对分析管道的一系列改进,为下一代在线BCI铺平道路,直接解决了这一限制。具体来说,我们介绍了一个开源研究框架,该框架具有模块化和可定制的硬件独立设计。该框架促进了人在环(HIL)模型训练和再训练,实时刺激控制,并实现了对脑电图(EEG)数据进行在线分类的迁移学习和云计算。使用网络浏览器技术在单独的显示器上显示受试者的刺激和研究人员的诊断。使用实验室流层标准和websockets发送消息。实时信号处理和分类,以及机器学习模型的训练,是由开源Python包Timeflux促进的。该框架在Linux上运行,MacOS,和Windows。虽然在线分析是BCI-HIL框架的主要目标,可以使用Python对EEG数据进行离线分析,MATLAB,和朱莉娅通过像MNE这样的包裹,EEGLAB,或FieldTrip。本文描述并讨论了人在环BCI研究平台的理想特性。BCI-HIL框架是在MIT许可下发布的,示例位于:bci。卢。se/bci-hil(或网址:github.com/bci-hil/bci-hil)。
    Brain-computer interfaces (BCIs) translate brain activity into digital commands for interaction with the physical world. The technology has great potential in several applied areas, ranging from medical applications to entertainment industry, and creates new conditions for basic research in cognitive neuroscience. The BCIs of today, however, offer only crude online classification of the user\'s current state of mind, and more sophisticated decoding of mental states depends on time-consuming offline data analysis. The present paper addresses this limitation directly by leveraging a set of improvements to the analytical pipeline to pave the way for the next generation of online BCIs. Specifically, we introduce an open-source research framework that features a modular and customizable hardware-independent design. This framework facilitates human-in-the-loop (HIL) model training and retraining, real-time stimulus control, and enables transfer learning and cloud computing for the online classification of electroencephalography (EEG) data. Stimuli for the subject and diagnostics for the researcher are shown on separate displays using web browser technologies. Messages are sent using the Lab Streaming Layer standard and websockets. Real-time signal processing and classification, as well as training of machine learning models, is facilitated by the open-source Python package Timeflux. The framework runs on Linux, MacOS, and Windows. While online analysis is the main target of the BCI-HIL framework, offline analysis of the EEG data can be performed with Python, MATLAB, and Julia through packages like MNE, EEGLAB, or FieldTrip. The paper describes and discusses desirable properties of a human-in-the-loop BCI research platform. The BCI-HIL framework is released under MIT license with examples at: bci.lu.se/bci-hil (or at: github.com/bci-hil/bci-hil).

    生态系统服务(ESs)的供需是生态安全模式(ESP)与人类福祉之间的桥梁。本研究提出了“供给-需求-走廊-节点”的ESP研究框架,中国,作为一个研究案例,为构建ESP提供了新的视角。该框架分为四个部分:根据ESs供应确定生态源;利用多源经济社会数据来表征ESs的需求并构建阻力面;通过使用LinkageMapper来定义研究区域的生态走廊;并确定沿生态走廊的关键生态保护/恢复区域。结果表明,徐州市ESs供应源面积为573.89km2,占全市总面积的5.19%。105个生态廊道的空间分布显示,城市中部存在多个密集的生态廊道,但在西北部和东南部很少。共有14个生态保护区主要位于市区南部,10个生态修复区主要位于市区中部和北部,总面积4.74km2。本文的研究结果将有助于发展ESPs和确定徐州重要的生态保护/恢复区域,中国。该研究框架可能用于其他领域。
    The supply-demand for ecosystem services (ESs) is the bridge between ecological security patterns (ESPs) and human wellbeing. This study proposed a research framework of ESP of \"supply-demand-corridor-node\" and took Xuzhou, China, as a research case, providing a new perspective for the construction of ESPs. The framework was divided into four sections: identifying the ecological source based on the ESs supply; utilizing multi-source economic-social data to characterize the demand of ESs and constructing a resistance surface; defining the ecological corridor in the study area by employing the Linkage Mapper; and identifying crucial ecological protection/restoration areas along the ecological corridor. The results showed that the area of the supply source of ESs in Xuzhou City is 573.89 km2, accounting for 5.19% of the city\'s total area. The spatial distribution of 105 ecological corridors revealed that there were multiple and dense ecological corridors in the middle of the city, but few in the northwest and southeast. A total of 14 ecological protection areas were located primarily in the south of the urban area, and 10 ecological restoration areas were located primarily in the middle and north of the urban area, with a total area of 4.74 km2. The findings of this article will be useful in developing ESPs and determining important ecological protection/restoration areas in Xuzhou, China. The research framework could potentially be used in other areas.

    移动健康干预(MHI)已经解决了一系列医疗保健挑战,并已使用随机对照试验(RCT)进行了评估,以确定临床有效性。使用PRISMA,我们对MHI的RCT进行了系统的文献综述,并确定了70项研究,这些研究使用Nickerson-Varshney-Muntermann(NVM)分类法进行了分析和分类。从分类的结果迭代中,我们从分类研究中提取了见解。RCT涵盖广泛的健康状况,包括慢性病,一般健康,不健康的做法,计划生育,生命的终结,和移植后的护理。RCT使用的MHI也各不相同,尽管大多数研究没有发现MHIs和常规治疗之间的显著差异。基于MHI的RCT的挑战包括技术的使用,延迟结果,患者招募,保留患者,和复杂的监管要求。这些差异可能导致更高的I型/II型错误率。进一步的考虑因素是基础设施的影响,背景和文化因素,以及干预本身的技术相关性降低。最后,由于大多数结果的延迟效应,持续时间不足的随机对照试验无法衡量显著,持久的改进。利用70项已确定研究的见解,我们制定了现有RCT的分类以及基于MHI的RCT的指南和未来RCT的研究框架.该框架为(A)MHIs的个性化提供了机会,(b)使用更丰富的技术,和(c)RCTs的新兴领域。
    Mobile Health Interventions (MHIs) have addressed a range of healthcare challenges and have been evaluated using Randomized Controlled Trials (RCTs) to establish clinical effectiveness. Using PRISMA we conducted a systematic literature review of RCTs for MHIs and identified 70 studies which were analyzed and classified using Nickerson-Varshney-Muntermann (NVM) taxonomy. From the resultant iterations of the taxonomy, we extracted insights from the categorized studies. RCTs cover a wide range of health conditions including chronic diseases, general wellness, unhealthy practices, family planning, end-of-life, and post-transplant care. The MHIs that were utilized by the RCTs were varied as well, although most studies did not find significant differences between MHIs and usual care. The challenges for MHI-based RCTs include the use of technologies, delayed outcomes, patient recruitment, patient retention, and complex regulatory requirements. These variances can lead to a higher rate of Type I/Type II errors. Further considerations are the impact of infrastructure, contextual and cultural factors, and reductions in the technological relevancy of the intervention itself. Finally, due to the delayed effect of most outcomes, RCTs of insufficient duration are unable to measure significant, lasting improvements. Using the insights from seventy identified studies, we developed a classification of existing RCTs along with guidelines for MHI-based RCTs and a research framework for future RCTs. The framework offers opportunities for (a) personalization of MHIs, (b) use of richer technologies, and (c) emerging areas for RCTs.

    无论变革举措在当代组织中的普遍性和价值如何,这些经常面临员工的抵制。这种阻力是变化接受者对变化的认知和行为反应的结果。为了更好地了解变化反应的原因和影响,需要对先前的研究有一个整体的看法。因此,我们对这一主题进行了系统的文献综述。我们将现有研究分为四个主要和几个子类别:微观反应和宏观反应。我们沿着研究问题和挑战分析了变化反应的新兴领域的基本特征,(甚至负面)反应的好处,管理意义,并提出未来的研究机会。
    Regardless of the prevalence and value of change initiatives in contemporary organizations, these often face resistance by employees. This resistance is the outcome of change recipients\' cognitive and behavioral reactions towards change. To better understand the causes and effects of reactions to change, a holistic view of prior research is needed. Accordingly, we provide a systematic literature review on this topic. We categorize extant research into four major and several subcategories: micro and macro reactions. We analyze the essential characteristics of the emerging field of change reactions along research issues and challenges, benefits of (even negative) reactions, managerial implications, and propose future research opportunities.

    联合国健康老龄化十年(2020-2030年)的使命是改善老年人的生活,他们的家庭和社区。在本文中,我们为研究人员创造了一个概念框架和研究议程,以解决十年行动项目的知识。该框架建立在健康老龄化的主要组成部分的基础上:(工作和家庭)生活过程中的环境(突出社会和社区)朝着(个人,家庭成员和社区)。将每个领域内的知识差距确定为优先研究行动。在社会环境中,提出了关于年龄歧视和家庭主义的询问信念,以说明对老年人的宏观方法如何影响他们的经历。我们需要询问社区在多大程度上是变老的好地方;以及他们是否有足够的资源来支持老年居民。建议进一步阐明整个工作和家庭生活过程中的轨迹和转折点,以更好地了解它们的多样性以及它们在以后的生活中带来足够的财政和社会资源的程度。建议健康的组成部分来监测老年人生活的改善,他们的家庭和社区。反映十年行动的区域和国家战略可以为研究人员的优先事项提供信息。
    The mission of UN Decade of Healthy Ageing (2020-2030) is to improve the lives of older people, their families and their communities. In this paper, we create a conceptual framework and research agenda for researchers to knowledge to address the Decade action items. The framework builds on the main components of healthy ageing: Environments (highlighting society and community) across life courses (of work and family) toward wellbeing (of individuals, family members and communities). Knowledge gaps are identified within each area as priority research actions. Within societal environments, interrogating beliefs about ageism and about familism are proposed as a way to illustrate how macro approaches to older people influence their experiences. We need to interrogate the extent to which communities are good places to grow old; and whether they have sufficient resources to be supportive to older residents. Further articulation of trajectories and turning points across the full span of work and of family life courses is proposed to better understand their diversities and the extent to which they lead to adequate financial and social resources in later life. Components of wellbeing are proposed to monitor improvement in the lives of older people, their families and communities. Researcher priorities can be informed by regional and national strategies reflecting Decade actions.
