    UNASSIGNED: Metaproteomics offers insights into the function of complex microbial communities while it is also capable of revealing microbe-microbe and host-microbe interactions. Data-independent acquisition (DIA) mass spectrometry is an emerging technology, which holds great potential to achieve deep and accurate metaproteomics with higher reproducibility yet still facing a series of challenges due to the inherent complexity of metaproteomics and DIA data.
    UNASSIGNED: This review offers an overview of the DIA metaproteomics approaches, covering aspects such as database construction, search strategy, and data analysis tools. Several cases of current DIA metaproteomics studies are presented to illustrate the procedures. Important ongoing challenges are also highlighted. Future perspectives of DIA methods for metaproteomics analysis are further discussed. Cited references are searched through and collected from Google Scholar and PubMed.
    UNASSIGNED: Considering the inherent complexity of DIA metaproteomics data, data analysis strategies specifically designed for interpretation is imperative. From this point of view, we anticipate that deep learning methods and de novo sequencing methods will become more prevalent in the future, potentially improving protein coverage in metaproteomics. Moreover, the advancement of metaproteomics also depends on the development of sample preparation methods, data analysis strategies, etc. These factors are key to unlocking the full potential of metaproteomics.

    背景:数据缺失对个体连续血糖监测(CGM)数据的影响未知,但会影响患者的临床决策。
    目的:我们旨在研究数据丢失对来自连续血糖监测仪的个体患者血糖指标的影响,并评估其对临床决策的影响。
    方法:使用FreeStyleLibre传感器(雅培糖尿病护理)收集1型和2型糖尿病患者的CGM数据。我们从每个患者中选择了7-28天的24小时连续数据,没有任何缺失值。为了模拟真实世界的数据丢失,从5%到50%的缺失数据被引入到数据集中.从这个修改的数据集中,临床指标,包括低于范围的时间(TBR),TBR等级2(TBR2),和其他常见的血糖指标在有和没有数据丢失的数据集中计算。由于数据丢失而导致血糖指标相关偏差的记录,根据临床专家的判断,被定义为专家面板边界误差(εEPB)。这些误差表示为记录总数的百分比。研究了葡萄糖管理指标<53mmol/mol的记录错误。
    结果:共有84名患者在28天内完成了798次记录。5%-50%的数据丢失7-28天的记录,对于TBR,εEPB从798(0.0%)中的0到736(20.0%)中的147,而对于TBR2,从612(0.0%)中的0到408(5.4%)中的22。在14天录音的情况下,由于786例中的2例(0.3%)和522例中的32例(6.1%)的数据丢失,TBR和TBR2发作完全消失,分别。然而,消失的TBR和TBR2的初始值相对较小(<0.1%)。在葡萄糖管理指标<53mmol/mol的记录中,εEPB为9.6%持续14天,数据损失为30%。
    结论:在14天的CGM记录中,数据丢失最多30%,缺失数据对各种血糖指标的临床解释影响最小.
    背景:ClinicalTrials.govNCT05584293;https://clinicaltrials.gov/study/NCT05584293。
    BACKGROUND: The impact of missing data on individual continuous glucose monitoring (CGM) data is unknown but can influence clinical decision-making for patients.
    OBJECTIVE: We aimed to investigate the consequences of data loss on glucose metrics in individual patient recordings from continuous glucose monitors and assess its implications on clinical decision-making.
    METHODS: The CGM data were collected from patients with type 1 and 2 diabetes using the FreeStyle Libre sensor (Abbott Diabetes Care). We selected 7-28 days of 24 hours of continuous data without any missing values from each individual patient. To mimic real-world data loss, missing data ranging from 5% to 50% were introduced into the data set. From this modified data set, clinical metrics including time below range (TBR), TBR level 2 (TBR2), and other common glucose metrics were calculated in the data sets with and that without data loss. Recordings in which glucose metrics deviated relevantly due to data loss, as determined by clinical experts, were defined as expert panel boundary error (εEPB). These errors were expressed as a percentage of the total number of recordings. The errors for the recordings with glucose management indicator <53 mmol/mol were investigated.
    RESULTS: A total of 84 patients contributed to 798 recordings over 28 days. With 5%-50% data loss for 7-28 days recordings, the εEPB varied from 0 out of 798 (0.0%) to 147 out of 736 (20.0%) for TBR and 0 out of 612 (0.0%) to 22 out of 408 (5.4%) recordings for TBR2. In the case of 14-day recordings, TBR and TBR2 episodes completely disappeared due to 30% data loss in 2 out of 786 (0.3%) and 32 out of 522 (6.1%) of the cases, respectively. However, the initial values of the disappeared TBR and TBR2 were relatively small (<0.1%). In the recordings with glucose management indicator <53 mmol/mol the εEPB was 9.6% for 14 days with 30% data loss.
    CONCLUSIONS: With a maximum of 30% data loss in 14-day CGM recordings, there is minimal impact of missing data on the clinical interpretation of various glucose metrics.
    BACKGROUND: ClinicalTrials.gov NCT05584293; https://clinicaltrials.gov/study/NCT05584293.

    循证实践是高质量姑息治疗提供的基础。然而,构成证据基础的临床试验通常在方法上不完善。在没有关键应用的情况下将他们的结论应用于临床实践环境可能会伤害患者。提供的提示可以帮助临床医生从临床试验结果中明智地推断,并避免轻信接受没有批评的发现。我们建议统计和数学专业知识是不必要的,而是对调查人员对某些设计选择的理由以及这些选择如何影响结果的强烈好奇心是关键。为了更全面地了解临床试验,这篇文章可以与作者对应的十条技巧文章一起使用,重点是设计临床试验。
    Evidence-based practice is foundational to high-quality palliative care delivery. However, the clinical trials that compose the evidence base are often methodologically imperfect. Applying their conclusions without critical application to the clinical practice context can harm patients. The tips provided can help clinicians infer judiciously from clinical trial results and avoid credulously accepting findings without critique. We suggest that statistical and mathematical expertise is unnecessary, but rather a keen curiosity about investigators\' rationale for certain design choices and how these choices can affect results is key. For a more comprehensive understanding of clinical trials, this article can be used with the authors\' corresponding ten tips article that focuses on designing a clinical trial.

    目的:对零假设显著性检验的依赖往往导致对研究结果的误解。常见的误解包括统计学上无显著差异(p≥0.05)意味着组间没有差异,并且具有统计学意义的发现(p<0.05)是无偏的并且具有临床意义。我们旨在开发一种工具-结论生成器-来减轻这些误解。
    方法:我们回顾了结论生成器的内容,并使用已发布和模拟的数据验证了其输出。
    结果:结论生成器是一个免费的在线应用程序,旨在根据点估计和置信区间的值和临床解释为科学论文生成结论。支持相对和绝对效果度量。它提供了两种解释模式:(1)统计模式提供了对结果的准确统计解释,具有优势和非劣效性界限的可选规范;(2)临床模式评估用户指定的点估计和置信限度的临床重要性。两种模式都没有不受控制的偏见。用户必须指定小数的数量,有益效果的方向(例如,相对风险<1vs.>1),和详细程度(简洁与阐述)用于输出。验证证实了结论生成器解释研究结果的能力,考虑到随机误差和临床相关性,同时避免与零假设显著性检验相关的常见误解。
    结论:结论生成器通过强调估计和临床相关性而不是假设检验,促进了对研究结果的适当解释。
    OBJECTIVE: Reliance on null hypothesis significance testing often leads to misinterpretation of research results. Common misinterpretations include that a statistically nonsignificant difference (p ≥ 0.05) implies no difference between groups, and that a statistically significant finding (p < 0.05) is unbiased and clinically important. We aimed to develop a tool - the Conclusion Generator - to mitigate these misconceptions.
    METHODS: We reviewed the content of the Conclusion Generator and validated its output using published and simulated data.
    RESULTS: The Conclusion Generator is a free online application designed to generate conclusions for scientific papers based on the values and clinical interpretation of the point estimate and confidence interval. Both relative and absolute measures of effect are supported. It offers two modes for interpretation: (1) Statistical mode provides an accurate statistical interpretation of results, with an optional specification of superiority and noninferiority bounds; (2) Clinical mode evaluates the clinical importance of the point estimate and confidence limits as specified by the user. Both modes assume no uncontrolled biases. Users must specify the number of decimals, the direction of a beneficial effect (e.g., relative risk <1 vs. >1), and the level of detail (concise vs. elaborated) for the output. The validation confirmed the Conclusion Generator\'s capability to interpret research results, considering random error and clinical relevance, while avoiding common misinterpretations associated with null hypothesis significance testing.
    CONCLUSIONS: The Conclusion Generator facilitates an appropriate interpretation of research results by emphasizing estimation and clinical relevance over hypothesis testing.

    实用竣工计划,通常提供有关地下公用设施位置和空间位置的信息,已知包括不准确。多年来,对使用一系列传感设备进行公用事业调查的依赖增加了,以试图解决公用事业竣工的不准确性,并减轻挖掘活动期间地下公用事业意外罢工的高比率。已证明将数据融合到公用事业工程和调查实践中可以有效地生成具有更高准确性的信息。然而,数据解释的复杂性和相关的高昂成本,特别是对于大型项目,是限制因素。本文解决了数据解释的问题,成本,以及具有新颖框架的大规模实用程序映射,该框架通过将自动生成的初始映射中的数据与已构建的数据融合来生成概率推断。概率推断暴露了高度不确定性的区域,强调他们是进一步调查的主要目标。所提出的模型是三个主要过程的集合。首先,自动初始地图创建是一种新颖的贡献,通过使已识别的实用程序附件服从实用程序推理规则来支持快速实用程序映射。第二和第三过程包括将创建的初始效用图与来自效用竣工或历史卫星图像数据的可用知识融合,然后使用置信度值估计器评估不确定性。所提出的框架通过生成最终的概率效用图,超越了先前作品中对掩埋效用位置的点估计,揭示归因于连接地上特征的每个段的置信水平。在这种方法中,公用事业基础设施以低成本快速映射,将更详细的效用调查的范围限制在低置信度区域。在抵制过时时,该框架的另一个独特优势是映射的动态特性,以便在新知识到来时自动更新信息。这最终最大限度地减少了实用的问题,即随着时间的推移,建筑精度下降。
    Utility as-built plans, which typically provide information about underground utilities\' position and spatial locations, are known to comprise inaccuracies. Over the years, the reliance on utility investigations using an array of sensing equipment has increased in an attempt to resolve utility as-built inaccuracies and mitigate the high rate of accidental underground utility strikes during excavation activities. Adapting data fusion into utility engineering and investigation practices has been shown to be effective in generating information with improved accuracy. However, the complexities in data interpretation and associated prohibitive costs, especially for large-scale projects, are limiting factors. This paper addresses the problem of data interpretation, costs, and large-scale utility mapping with a novel framework that generates probabilistic inferences by fusing data from an automatically generated initial map with as-built data. The probabilistic inferences expose regions of high uncertainty, highlighting them as prime targets for further investigations. The proposed model is a collection of three main processes. First, the automatic initial map creation is a novel contribution supporting rapid utility mapping by subjecting identified utility appurtenances to utility inference rules. The second and third processes encompass the fusion of the created initial utility map with available knowledge from utility as-builts or historical satellite imagery data and then evaluating the uncertainties using confidence value estimators. The proposed framework transcends the point estimation of buried utility locations in previous works by producing a final probabilistic utility map, revealing a confidence level attributed to each segment linking aboveground features. In this approach, the utility infrastructure is rapidly mapped at a low cost, limiting the extent of more detailed utility investigations to low-confidence regions. In resisting obsolescence, another unique advantage of this framework is the dynamic nature of the mapping to automatically update information upon the arrival of new knowledge. This ultimately minimizes the problem of utility as-built accuracies dwindling over time.

    背景:最近电子健康的增长是前所未有的,特别是在COVID-19大流行之后。在eHealth中,可穿戴技术越来越多地被采用,因为它可以在日常生活环境中提供慢性和急性条件的远程监控。可穿戴技术可用于监测和跟踪日常生活环境中身体和心理压力的关键指标,为临床医生提供有用的信息。关键挑战之一是以易于解释的方式向临床医生提供大量可穿戴数据,以做出明智的决定。
    目的:这项研究的目的是设计一个可穿戴数据仪表板,名为CarePortal,呈现对临床医生有意义的可穿戴数据的分析可视化。该研究分为2个主要研究目标:了解临床医生对可穿戴数据解释和可视化的需求,并为Web应用程序开发系统架构,以可视化可穿戴数据和相关分析。
    方法:我们使用了从116名经历创伤的青少年参与者收集的可穿戴数据集。两个星期,参与者佩戴MicrosoftBand,记录心率(HR)等生理传感器数据.共收集834天的HR数据。要设计CarePortal仪表板,我们使用参与式设计方法,直接与具有临床心理学和神经心理学背景的临床医生(利益相关者)进行互动.总共从罗德岛医院和马萨诸塞州纪念健康大学招募了8名临床医生。该研究涉及参与式研讨会的5个阶段,并从了解临床医生的需求开始。在研究结束时使用用户体验问卷来定量评估用户体验。生理指标,如每日和每小时最大值,minimum,平均,HR和HR变异性的SD,以及基于人力资源的活动水平,已确定。本研究调查了可穿戴数据的各种数据可视化绘图方法,包括雷达图,堆叠条形图,散点图与线图相结合,简单的条形图,和箱线图。
    结果:在了解临床医生的需求后,我们创建了一个CarePortal仪表板。我们研讨会的结果表明,整体临床医生更喜欢汇总信息,如每日HR而不是连续HR,并希望看到可穿戴传感器数据在一段时间内的趋势(例如,days).在用户体验问卷中,获得1.4分,这表明CarePortal的使用令人兴奋(问题5),收到了类似的分数,表明CarePortal是领先的(问题8)。平均而言,临床医生报告说,CarePortal具有支持性,可用于做出知情决策.
    结论:我们得出的结论是,与可穿戴传感器数据可视化技术集成的CarePortal仪表板将是未来临床医生可以接受的工具。
    BACKGROUND: The recent growth of eHealth is unprecedented, especially after the COVID-19 pandemic. Within eHealth, wearable technology is increasingly being adopted because it can offer the remote monitoring of chronic and acute conditions in daily life environments. Wearable technology may be used to monitor and track key indicators of physical and psychological stress in daily life settings, providing helpful information for clinicians. One of the key challenges is to present extensive wearable data to clinicians in an easily interpretable manner to make informed decisions.
    OBJECTIVE: The purpose of this research was to design a wearable data dashboard, named CarePortal, to present analytic visualizations of wearable data that are meaningful to clinicians. The study was divided into 2 main research objectives: to understand the needs of clinicians regarding wearable data interpretation and visualization and to develop a system architecture for a web application to visualize wearable data and related analytics.
    METHODS: We used a wearable data set collected from 116 adolescent participants who experienced trauma. For 2 weeks, participants wore a Microsoft Band that logged physiological sensor data such as heart rate (HR). A total of 834 days of HR data were collected. To design the CarePortal dashboard, we used a participatory design approach that interacted directly with clinicians (stakeholders) with backgrounds in clinical psychology and neuropsychology. A total of 8 clinicians were recruited from the Rhode Island Hospital and the University of Massachusetts Memorial Health. The study involved 5 stages of participatory workshops and began with an understanding of the needs of clinicians. A User Experience Questionnaire was used at the end of the study to quantitatively evaluate user experience. Physiological metrics such as daily and hourly maximum, minimum, average, and SD of HR and HR variability, along with HR-based activity levels, were identified. This study investigated various data visualization graphing methods for wearable data, including radar charts, stacked bar plots, scatter plots combined with line plots, simple bar plots, and box plots.
    RESULTS: We created a CarePortal dashboard after understanding the clinicians\' needs. Results from our workshops indicate that overall clinicians preferred aggregate information such as daily HR instead of continuous HR and want to see trends in wearable sensor data over a period (eg, days). In the User Experience Questionnaire, a score of 1.4 was received, which indicated that CarePortal was exciting to use (question 5), and a similar score was received, indicating that CarePortal was the leading edge (question 8). On average, clinicians reported that CarePortal was supportive and can be useful in making informed decisions.
    CONCLUSIONS: We concluded that the CarePortal dashboard integrated with wearable sensor data visualization techniques would be an acceptable tool for clinicians to use in the future.
