    事件发生时间预测是生物发现的关键任务,实验医学,和临床护理。对于神经系统疾病尤其如此,在神经系统疾病中,可靠的生物标志物的开发通常受到可视化和采样相关细胞和分子病理学的困难的限制。迄今为止,由于易于使用,许多工作都依赖于Cox回归,尽管有证据表明这个模型包括不正确的假设。我们已经在完全可定制的“应用程序”和随附的在线门户中实现了一组用于时间到事件建模的深度学习和样条模型,这两种方法都可用于非专家用户对任何疾病的任何时间到事件分析。我们的在线门户为包括患者在内的最终用户提供了容量,神经内科临床医生,和研究人员,使用经过训练的模型访问和执行预测,并为模型改进提供新数据,所有这些都在数据安全的环境中。我们展示了一个使用我们的应用程序的管道,包括三个用例,包括缺失数据的填补,超参数调整,模型训练和独立验证。我们表明,预测最适合用于下游应用,如基因发现,生物标志物解释,和个性化的药物选择。我们展示了集成配置的效率,包括深度学习模型的集中培训。我们已经结合时间到事件预测模型优化了用于填补缺失数据的管道。总的来说,我们提供了一个强大且可访问的工具来开发,访问和共享时间到事件预测模型;所有软件和教程均可在www上获得。predictte.org。
    Time-to-event prediction is a key task for biological discovery, experimental medicine, and clinical care. This is particularly true for neurological diseases where development of reliable biomarkers is often limited by difficulty visualising and sampling relevant cell and molecular pathobiology. To date, much work has relied on Cox regression because of ease-of-use, despite evidence that this model includes incorrect assumptions. We have implemented a set of deep learning and spline models for time-to-event modelling within a fully customizable \'app\' and accompanying online portal, both of which can be used for any time-to-event analysis in any disease by a non-expert user. Our online portal includes capacity for end-users including patients, Neurology clinicians, and researchers, to access and perform predictions using a trained model, and to contribute new data for model improvement, all within a data-secure environment. We demonstrate a pipeline for use of our app with three use-cases including imputation of missing data, hyperparameter tuning, model training and independent validation. We show that predictions are optimal for use in downstream applications such as genetic discovery, biomarker interpretation, and personalised choice of medication. We demonstrate the efficiency of an ensemble configuration, including focused training of a deep learning model. We have optimised a pipeline for imputation of missing data in combination with time-to-event prediction models. Overall, we provide a powerful and accessible tool to develop, access and share time-to-event prediction models; all software and tutorials are available at www.predictte.org.

    每年,超过1900万例癌症被诊断,这个数字每年都在增加。由于标准治疗方案对不同类型的癌症有不同的成功率,了解个体肿瘤的生物学变得至关重要,特别是对于难以治疗的病例。个性化的高通量分析,使用下一代测序,允许全面检查活检标本。此外,这项技术的广泛使用产生了关于癌症特异性基因改变的大量信息。然而,已确定的改变与已证实的对蛋白质功能的影响之间存在显著差距.这里,我们提出了一个生物信息学管道,能够快速分析错义突变对已知致癌蛋白的稳定性和功能的影响。该管道与一个预测器相结合,该预测器汇总了整个管道中使用的不同工具的输出,提供单个概率得分,达到86%以上的平衡精度。该管道采用了虚拟筛选方法,以建议考虑使用FDA/EMA批准的潜在药物进行治疗。我们展示了三个案例研究,以证明该管道的及时实用性。为了促进癌症相关突变的获取和分析,我们把管道打包成一个网络服务器,它可以在https://loschmidt上免费获得。Chemi.Muni.cz/prejectonco/。科学贡献这项工作提出了一种新颖的生物信息学管道,该管道集成了多种计算工具来预测错义突变对肿瘤学感兴趣的蛋白质的影响。管道独特地结合了快速蛋白质建模,稳定性预测,以及虚拟药物筛选的进化分析,同时为精准肿瘤学提供可操作的见解。这种全面的方法通过自动解释突变并建议潜在的治疗方法,超越了现有的工具。从而努力弥合测序数据与临床应用之间的差距。
    Every year, more than 19 million cancer cases are diagnosed, and this number continues to increase annually. Since standard treatment options have varying success rates for different types of cancer, understanding the biology of an individual\'s tumour becomes crucial, especially for cases that are difficult to treat. Personalised high-throughput profiling, using next-generation sequencing, allows for a comprehensive examination of biopsy specimens. Furthermore, the widespread use of this technology has generated a wealth of information on cancer-specific gene alterations. However, there exists a significant gap between identified alterations and their proven impact on protein function. Here, we present a bioinformatics pipeline that enables fast analysis of a missense mutation\'s effect on stability and function in known oncogenic proteins. This pipeline is coupled with a predictor that summarises the outputs of different tools used throughout the pipeline, providing a single probability score, achieving a balanced accuracy above 86%. The pipeline incorporates a virtual screening method to suggest potential FDA/EMA-approved drugs to be considered for treatment. We showcase three case studies to demonstrate the timely utility of this pipeline. To facilitate access and analysis of cancer-related mutations, we have packaged the pipeline as a web server, which is freely available at https://loschmidt.chemi.muni.cz/predictonco/ .Scientific contributionThis work presents a novel bioinformatics pipeline that integrates multiple computational tools to predict the effects of missense mutations on proteins of oncological interest. The pipeline uniquely combines fast protein modelling, stability prediction, and evolutionary analysis with virtual drug screening, while offering actionable insights for precision oncology. This comprehensive approach surpasses existing tools by automating the interpretation of mutations and suggesting potential treatments, thereby striving to bridge the gap between sequencing data and clinical application.

    卵巢癌的遗传异质性表明需要个性化治疗方法。目前,很少有G蛋白偶联受体(GPCRs)被研究用于纳米药物的主动靶向,例如抗体偶联药物和载药纳米颗粒,突出了开发个性化治疗的被忽视潜力。为了解决卵巢癌的遗传异质性,未来的个性化方法可能包括识别癌症活检中表达的独特GPCRs,与个性化的GPCR靶向纳米药物相匹配,之前向肿瘤组织输送致命药物,手术期间和之后。在这里,我们报告了对公共核糖核酸测序(RNA-seq)基因表达数据的系统分析,这导致优先考虑13个GPCRs作为卵巢癌组织中频繁过表达的候选物。随后,来自腹水和卵巢癌细胞系的原发性卵巢癌细胞用于确认所选GPCRs的频繁基因表达。然而,表达水平在我们选择的样本中显示出高度的变异性,因此,支持并强调未来发展个案个性化定位方法的必要性。
    Genetic heterogeneity in ovarian cancer indicates the need for personalised treatment approaches. Currently, very few G-protein coupled receptors (GPCRs) have been investigated for active targeting with nanomedicines such as antibody-conjugated drugs and drug-loaded nanoparticles, highlighting a neglected potential to develop personalised treatment. To address the genetic heterogeneity of ovarian cancer, a future personalised approach could include the identification of unique GPCRs expressed in cancer biopsies, matched with personalised GPCR-targeted nanomedicines, for the delivery of lethal drugs to tumour tissue before, during and after surgery. Here we report on the systematic analysis of public ribonucleic acid-sequencing (RNA-seq) gene expression data, which led to prioritisation of 13 GPCRs as candidates with frequent overexpression in ovarian cancer tissues. Subsequently, primary ovarian cancer cells derived from ascites and ovarian cancer cell lines were used to confirm frequent gene expression for the selected GPCRs. However, the expression levels showed high variability within our selection of samples, therefore, supporting and emphasising the need for the future development of case-to-case personalised targeting approaches.

    Specific molecular and inflammatory endotypes have been identified for chronic respiratory disorders, including asthma and COPD (chronic obstructive pulmonary disease). These endotypes correspond with clinical aspects of disease, enabling targeted medicines to address certain pathophysiologic pathways, often referred to as \"precision medicine\". With respect to bronchiectasis, many comorbidities and underlying causes have been identified. Inflammatory endotypes have also been widely studied and reported. Additionally, several genes have been shown to affect disease progression. However, the lack of a clear classification has also hampered our understanding of the disease\'s natural course. The aim of this review is, thus, to summarize the current knowledge on biomarkers and actionable targets of this complex pathologic condition and to point out unmet needs, which are required in the design of effective diagnostic and therapeutic trials.

    The human transcriptome predominantly consists of noncoding RNAs (ncRNAs), transcripts that do not encode proteins. The noncoding transcriptome governs a multitude of pathophysiological processes, offering a rich source of next-generation biomarkers. Toward achieving a holistic view of disease, the integration of these transcripts with clinical records and additional data from omic technologies (\"multiomic\" strategies) has motivated the adoption of artificial intelligence (AI) approaches. Given their intricate biological complexity, machine learning (ML) techniques are becoming a key component of ncRNA-based research. This article presents an overview of the potential and challenges associated with employing AI/ML-driven approaches to identify clinically relevant ncRNA biomarkers and to decipher ncRNA-associated pathogenetic mechanisms. Methodological and conceptual constraints are discussed, along with an exploration of ethical considerations inherent to AI applications for healthcare and research. The ultimate goal is to provide a comprehensive examination of the multifaceted landscape of this innovative field and its clinical implications.

    背景:进行n-of-1试验以优化个体患者的健康技术评估。他们涉及一名患者接受治疗,介入和控制,在设定的时间段内连续,其顺序是随机决定的。尽管在医学研究中进行了n-1试验,但可以说它们具有更频繁地进行的效用。我们承担了美国国立卫生研究院(NIHR)委托DIAMOND(开发用于极低量治疗的n-of-1试验的通用方法)项目,以开发关键点,以帮助临床医生和研究人员设计和进行n-of-1试验。
    方法:关键点是通过举办利益相关者研讨会来开发的,接下来是研究团队内部的讨论,然后是利益相关者的传播和反馈事件。利益相关者研讨会寻求获得各种利益相关者的观点(包括临床医生,研究人员和患者代表)关于n-of-1试验的设计和使用。研究小组之间进行了讨论,以反思研讨会并起草要点。最后,研讨会的利益攸关方应邀参加了一次传播和反馈会议,会上介绍了拟议的要点,并获得了他们的反馈。
    结果:根据研讨会的见解和随后的讨论,制定了一组22个关键点。他们提供关于n-of-1试验何时可能是可行或适当的研究设计的指导,并讨论n-of-1试验设计中涉及的关键决定。包括确定适当的治疗周期和周期数,比较器的选择,推荐的随机化和致盲方法,冲洗期的使用和分析方法。
    结论:该项目开发的关键点将支持临床研究人员在设计n-of-1试验时了解关键考虑因素。希望他们将支持研究设计的更广泛实施。
    BACKGROUND: n-of-1 trials are undertaken to optimise the evaluation of health technologies in individual patients. They involve a single patient receiving treatments, both interventional and control, consecutively over set periods of time, the order of which is decided at random. Although n-of-1 trials are undertaken in medical research it could be argued they have the utility to be undertaken more frequently. We undertook the National Institute for Health Research (NIHR) commissioned DIAMOND (Development of generalisable methodology for n-of-1 trials delivery for very low volume treatments) project to develop key points to assist clinicians and researchers in designing and conducting n-of-1 trials.
    METHODS: The key points were developed by undertaking a stakeholder workshop, followed by a discussion within the study team and then a stakeholder dissemination and feedback event. The stakeholder workshop sought to gain the perspectives of a variety of stakeholders (including clinicians, researchers and patient representatives) on the design and use of n-of-1 trials. A discussion between the study team was held to reflect on the workshop and draft the key points. Lastly, the stakeholders from the workshop were invited to a dissemination and feedback session where the proposed key points were presented and their feedback gained.
    RESULTS: A set of 22 key points were developed based on the insights from the workshop and subsequent discussions. They provide guidance on when an n-of-1 trial might be a viable or appropriate study design and discuss key decisions involved in the design of n-of-1 trials, including determining an appropriate number of treatment periods and cycles, the choice of comparator, recommended approaches to randomisation and blinding, the use of washout periods and approaches to analysis.
    CONCLUSIONS: The key points developed in the project will support clinical researchers to understand key considerations when designing n-of-1 trials. It is hoped they will support the wider implementation of the study design.

    UNASSIGNED: The field of precision medicine endeavors to transform the healthcare industry by advancing individualised strategies for diagnosis, treatment modalities, and predictive assessments. This is achieved by utilizing extensive multidimensional biological datasets encompassing diverse components, such as an individual\'s genetic makeup, functional attributes, and environmental influences. Artificial intelligence (AI) systems, namely machine learning (ML) and deep learning (DL), have exhibited remarkable efficacy in predicting the potential occurrence of specific cancers and cardiovascular diseases (CVD).
    UNASSIGNED: We conducted a comprehensive scoping review guided by the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) framework. Our search strategy involved combining key terms related to CVD and AI using the Boolean operator AND. In August 2023, we conducted an extensive search across reputable scholarly databases including Google Scholar, PubMed, IEEE Xplore, ScienceDirect, Web of Science, and arXiv to gather relevant academic literature on personalised medicine for CVD. Subsequently, in January 2024, we extended our search to include internet search engines such as Google and various CVD websites. These searches were further updated in March 2024. Additionally, we reviewed the reference lists of the final selected research articles to identify any additional relevant literature.
    UNASSIGNED: A total of 2307 records were identified during the process of conducting the study, consisting of 564 entries from external sites like arXiv and 1743 records found through database searching. After 430 duplicate articles were eliminated, 1877 items that remained were screened for relevancy. In this stage, 1241 articles remained for additional review after 158 irrelevant articles and 478 articles with insufficient data were removed. 355 articles were eliminated for being inaccessible, 726 for being written in a language other than English, and 281 for not having undergone peer review. Consequently, 121 studies were deemed suitable for inclusion in the qualitative synthesis. At the intersection of CVD, AI, and precision medicine, we found important scientific findings in our scoping review. Intricate pattern extraction from large, complicated genetic datasets is a skill that AI algorithms excel at, allowing for accurate disease diagnosis and CVD risk prediction. Furthermore, these investigations have uncovered unique genetic biomarkers linked to CVD, providing insight into the workings of the disease and possible treatment avenues. The construction of more precise predictive models and personalised treatment plans based on the genetic profiles of individual patients has been made possible by the revolutionary advancement of CVD risk assessment through the integration of AI and genomics.
    UNASSIGNED: The systematic methodology employed ensured the thorough examination of available literature and the inclusion of relevant studies, contributing to the robustness and reliability of the study\'s findings. Our analysis stresses a crucial point in terms of the adaptability and versatility of AI solutions. AI algorithms designed in non-CVD domains such as in oncology, often include ideas and tactics that might be modified to address cardiovascular problems.
    UNASSIGNED: No funding received.
