    结论:VisiumHD的10XGenomics是第一个能够以亚细胞分辨率捕获与来自存档FFPE块的参考形态图像配对的全尺度转录组数据的商业平台。然而,捕获区域聚集到单细胞带来了挑战。Bin2cell通过利用形态学图像分割和基因表达信息,从最高分辨率数据(2μmbin)重建细胞。它与已建立的Python单细胞和空间转录组学软件兼容,并在几分钟内高效运行,而不需要GPU。我们证明了在小鼠脑和人类结肠直肠癌数据上使用默认8μmbin上的重建细胞时,下游分析的改进。
    方法:Bin2cell可在https://github.com/Teichlab/bin2cell获得,连同文档和使用示例,并可以从PIP安装。探针设计功能可在https://github.com/Teichlab/gene2probe获得。
    背景:可在线获得补充数据。
    CONCLUSIONS: Visium HD by 10X Genomics is the first commercially available platform capable of capturing full scale transcriptomic data paired with a reference morphology image from archived FFPE blocks at sub-cellular resolution. However, aggregation of capture regions to single cells poses challenges. Bin2cell reconstructs cells from the highest resolution data (2 μm bins) by leveraging morphology image segmentation and gene expression information. It is compatible with established Python single cell and spatial transcriptomics software, and operates efficiently in a matter of minutes without requiring a GPU. We demonstrate improvements in downstream analysis when using the reconstructed cells over default 8 μm bins on mouse brain and human colorectal cancer data.
    METHODS: Bin2cell is available at https://github.com/Teichlab/bin2cell, along with documentation and usage examples, and can be installed from pip. Probe design functionality is available at https://github.com/Teichlab/gene2probe.
    BACKGROUND: Supplementary data are available online.

    Osteosarcomas are intricate cellular ecosystems, where heterotypic interactions significantly influence disease progression and therapeutic outcomes. Despite their importance, a detailed understanding of their cellular composition and organizational structure remains elusive. In this study, we provide a comprehensive single-cell and spatially resolved transcriptomics analysis of human osteosarcomas. We construct a cellular meta-map to dissect spatial transcriptomic data, unveiling a detailed atlas of osteosarcoma compositional subgroups. We meticulously characterize the unique gene signatures and functional states of each subgroup and investigate the impact of chemotherapy on these cellular subpopulations. Additionally, our spatial transcriptomics analysis identifies a distinct spatial niche, located at the forefront of tumor necrotic zones, potentially associated with chemotherapy resistance. We also delve into the crosstalk between different cellular subgroups. This study furnishes a comprehensive transcriptional atlas of osteosarcoma\'s cellular architecture, enriching our comprehension of its complexity and laying the groundwork for more targeted therapeutic approaches.

    背景:许多国家已将COVID-19大流行的废水监测应用于其国家公共卫生监测措施。检测废水中SARS-CoV-2的最常用方法是定量逆转录酶-聚合酶链反应(RT-qPCR)和逆转录酶-液滴数字聚合酶链反应(RT-ddPCR)。以前的比较研究产生了相互矛盾的结果,因此,需要对这个问题进行更多的研究。
    目的:本研究旨在比较RT-qPCR和RT-ddPCR检测废水中SARS-CoV-2的效果。它还旨在调查分析管道变化的影响,包括RNA提取试剂盒,RT-PCR试剂盒,和靶基因检测,关于结果。另一个目的是找到一种用于低资源设置的检测方法。
    方法:我们比较了2种RT-qPCR试剂盒,TaqManRT-qPCR和定量RT-qPCR,和基于灵敏度的RT-ddPCR,阳性率,可变性,废水中SARS-CoV-2基因拷贝数与COVID-19发病率的相关性。此外,我们比较了两种RNA提取方法,基于柱状和磁珠。此外,我们评估了两种RT-qPCR的靶基因检测方法,N1和N2,以及用于ddPCRN1和E的2个靶基因测定。基于逆转录链入侵的扩增(RT-SIBA)用于定性检测废水中的SARS-CoV-2。
    结果:我们的结果表明,检测废水中SARS-CoV-2的最灵敏方法是RT-ddPCR。阳性率最高(26/30),检测限最低(0.06个基因拷贝/μL)。然而,利用TaqManRT-qPCR技术,获得了废水中COVID-19发病率与SARS-CoV-2基因拷贝数的最佳相关性(相关系数[CC]=0.697,P<.001)。我们发现TaqManRT-qPCR试剂盒和QuantiTectRT-qPCR试剂盒之间的灵敏度存在显着差异,第一个具有比后者明显更低的检测限和更高的阳性率。此外,N1靶基因检测对两种RT-qPCR试剂盒最敏感,而使用RT-ddPCR在基因靶标之间没有发现显着差异。此外,当使用TaqManRT-qPCR试剂盒时,使用不同的RNA提取试剂盒会影响结果。RT-SIBA能够检测废水中的SARS-CoV-2RNA。
    结论:作为我们的研究,以及以前的大多数研究,显示RT-ddPCR比RT-qPCR更敏感,应考虑将其用于SARS-CoV-2的废水监测,特别是如果在人群中传播的SARS-CoV-2的数量很低。所有的分析步骤必须优化废水监测,因为我们的研究表明,所有的分析步骤,包括RNA提取的相容性,RT-PCR试剂盒,和靶基因测定影响结果。此外,我们的研究表明,如果定性结果足够,RT-SIBA可用于检测废水中的SARS-CoV-2。
    Many countries have applied the wastewater surveillance of the COVID-19 pandemic to their national public health monitoring measures. The most used methods for detecting SARS-CoV-2 in wastewater are quantitative reverse transcriptase-polymerase chain reaction (RT-qPCR) and reverse transcriptase-droplet digital polymerase chain reaction (RT-ddPCR). Previous comparison studies have produced conflicting results, thus more research on the subject is required.
    This study aims to compare RT-qPCR and RT-ddPCR for detecting SARS-CoV-2 in wastewater. It also aimed to investigate the effect of changes in the analytical pipeline, including the RNA extraction kit, RT-PCR kit, and target gene assay, on the results. Another aim was to find a detection method for low-resource settings.
    We compared 2 RT-qPCR kits, TaqMan RT-qPCR and QuantiTect RT-qPCR, and RT-ddPCR based on sensitivity, positivity rates, variability, and correlation of SARS-CoV-2 gene copy numbers in wastewater to the incidence of COVID-19. Furthermore, we compared 2 RNA extraction methods, column- and magnetic-bead-based. In addition, we assessed 2 target gene assays for RT-qPCR, N1 and N2, and 2 target gene assays for ddPCR N1 and E. Reverse transcription strand invasion-based amplification (RT-SIBA) was used to detect SARS-CoV-2 from wastewater qualitatively.
    Our results indicated that the most sensitive method to detect SARS-CoV-2 in wastewater was RT-ddPCR. It had the highest positivity rate (26/30), and its limit of detection was the lowest (0.06 gene copies/µL). However, we obtained the best correlation between COVID-19 incidence and SARS-CoV-2 gene copy number in wastewater using TaqMan RT-qPCR (correlation coefficient [CC]=0.697, P<.001). We found a significant difference in sensitivity between the TaqMan RT-qPCR kit and the QuantiTect RT-qPCR kit, the first having a significantly lower limit of detection and a higher positivity rate than the latter. Furthermore, the N1 target gene assay was the most sensitive for both RT-qPCR kits, while no significant difference was found between the gene targets using RT-ddPCR. In addition, the use of different RNA extraction kits affected the result when the TaqMan RT-qPCR kit was used. RT-SIBA was able to detect SARS-CoV-2 RNA in wastewater.
    As our study, as well as most of the previous studies, has shown RT-ddPCR to be more sensitive than RT-qPCR, its use in the wastewater surveillance of SARS-CoV-2 should be considered, especially if the amount of SARS-CoV-2 circulating in the population was low. All the analysis steps must be optimized for wastewater surveillance as our study showed that all the analysis steps including the compatibility of the RNA extraction, the RT-PCR kit, and the target gene assay influence the results. In addition, our study showed that RT-SIBA could be used to detect SARS-CoV-2 in wastewater if a qualitative result is sufficient.

    BACKGROUND: The genetic and environmental aetiology of autistic and Attention Deficit Hyperactivity Disorder (ADHD) traits is known to vary spatially, but does this translate into variation in the association of specific common genetic variants?
    METHODS: We mapped associations between polygenic scores for autism and ADHD and their respective traits in the Avon Longitudinal Study of Parents and Children (N = 4,255-6,165) across the area surrounding Bristol, UK, and compared them to maps of environments associated with the prevalence of autism and ADHD.
    RESULTS: Our results suggest genetic associations vary spatially, with consistent patterns for autistic traits across polygenic scores constructed at different p-value thresholds. Patterns for ADHD traits were more variable across thresholds. We found that the spatial distributions often correlated with known environmental influences.
    CONCLUSIONS: These findings shed light on the factors that contribute to the complex interplay between the environment and genetic influences in autistic and ADHD traits.

    尼日利亚一直报告儿童疾病患病率高和五岁以下儿童死亡率高。疫苗接种是一种具有成本效益的预防儿童疾病的战略。因此,这项研究旨在确定尼日利亚12-23个月儿童疫苗接种不完全(IV)的决定因素.这项横断面设计研究利用了2018年尼日利亚人口与健康调查(NDHS)数据集。采用两阶段整群抽样技术选择育龄妇女(n=5475),年龄在12-23个月之间。结果变量是儿童对儿童疾病的IV。使用集成嵌套拉普拉斯近似和贝叶斯二元回归模型(α0.05)分析数据。使用ArcGIS软件产生不完全疫苗接种的可视化。儿童的平均年龄为15.1±3.2个月,接种疫苗的中位数量为4。北部地区对IV做出了很大贡献。与年龄在15-24岁的年轻女性相比,年龄在25-34岁(aOR=0.67,95%CI=0.54-0.82,p<0.05)和35-49岁(aOR=0.59,95CI=0.46-0.77,p<0.05)的女性发生IV的可能性较低。教育水平的提高降低了IV的风险。IV的其他预测因素是在医疗机构分娩(aOR=0.64,95%CI=053-0.76,p<0.05),和培养基暴露(aOR=0.63,95CI=0.54-0.79,p<0.05)。母亲的特征解释了IV中大部分的变异性,社区和州级因素的总体贡献相对较小(p<0.05)。尼日利亚儿童疾病的IV水平很高。然而,各地区和其他社会经济群体之间存在差异。需要做出更多努力来改善尼日利亚的疫苗接种宣传计划和运动。
    High childhood disease prevalence and under-five mortality rates have been consistently reported in Nigeria. Vaccination is a cost-effective preventive strategy against childhood diseases. Therefore, this study aimed to identify the determinants of Incomplete Vaccination (IV) among children aged 12-23 months in Nigeria. This cross-sectional design study utilized the 2018 Nigeria Demographic and Health Survey (NDHS) dataset. A two-stage cluster sampling technique was used to select women of reproductive age who have children (n = 5475) aged 12-23 months. The outcome variable was IV of children against childhood diseases. Data were analyzed using Integrated Nested Laplace Approximation and Bayesian binary regression models (α0.05). Visualization of incomplete vaccination was produced using the ArcGIS software. Children\'s mean age was 15.1 ± 3.2 months and the median number of vaccines received was four. Northern regions contributed largely to the IV. The likelihood of IV was lower among women aged 25-34 years (aOR = 0.67, 95% CI = 0.54-0.82, p < 0.05) and 35-49 years (aOR = 0.59, 95%CI = 0.46-0.77, p < 0.05) compared to younger women in the age group 15-24 years. An increasing level of education reduces the risk of odds of IV. Other predictors of IV were delivery at the health facility (aOR = 0.64, 95% CI = 053-0.76, p < 0.05), and media exposure (aOR = 0.63, 95%CI = 0.54-0.79, p < 0.05). Mothers\' characteristics explained most of the variability in the IV, relatively to smaller overall contributions from the community and state-level factors (p < 0.05). The level of IV against childhood diseases was high in Nigeria. However, disparities exist across the regions and other socioeconomic segments of the population. More efforts are required to improve vaccination sensitization programs and campaigns in Nigeria.

    通货膨胀是印度尼西亚需要控制的宏观经济问题之一。由于商品和服务成本的普遍上涨,通货膨胀可能会发生。印度尼西亚2008年至2023年的年度通货膨胀率波动很大,有几个时期尚未实现通胀目标。控制通货膨胀的方法之一是对即将到来的时期进行预测。爪哇岛是印度尼西亚经济和国内生产总值(GDP)的最大贡献者,因此可以将其视为衡量印度尼西亚整体通货膨胀率的一般指标。因此,本研究中使用的数据是爪哇岛每个省从2008年1月到2023年12月的每月通货膨胀。本研究采用两种方法,用于单变量时间序列预测的自回归综合移动平均(ARIMA)和用于具有空间因子的多变量时间序列预测的广义时空ARIMA(GSTARIMA)。将比较两个模型的结果,以确定哪个模型具有更好的准确性。基于RMSE值,GSTARIMA模型的平均RMSE值最小,与平均RMSE值0.319的ARIMA模型相比,这是0.113,因此可以得出结论,增加空间因素可以提高爪哇岛通货膨胀预测的准确性。•本文旨在获得爪哇岛的通货膨胀率预测,以确定更好的控制商品和服务成本的政策。•使用GSTARIMA方法的最佳模型是GSTARMA(1,1),其距离矩阵表明每个位置的坐标点增加了通货膨胀率预测的性能。•结果表明,GSTARIMA在基于RMSE值的爪哇岛通货膨胀预测中具有比ARIMA更好的准确性。
    Inflation is one of macroeconomic issues in Indonesia that needs to be controlled. Inflation could happen because of widespread increases in the cost of goods and services. Annual inflation rate in Indonesia on 2008 to 2023 are quite fluctuating and several periods are not achieved inflation target yet. One of the ways to control inflation is by making predictions for the upcoming period. Java Island is the biggest contributor on economy and Gross Domestic Product (GDP) in Indonesia so it can be considered as general indicator to measure overall inflation rate of Indonesia. Thus, data used in this study is monthly inflation at each province in Java Island from January 2008 to December 2023. This study using two methods, Autoregressive Integrated Moving Average (ARIMA) for univariate time series prediction and Generalized Space-Time ARIMA (GSTARIMA) for multivariate time series prediction with a spatial factor. The results of both models will be compared to determine which model has better accuracy. Based on RMSE value, GSTARIMA model has least average RMSE value, which is 0.113 compared with ARIMA model which has average RMSE value 0.319 thus it can conclude that spatial factors addition could increase accuracy on inflation prediction in Java Island.•This paper purposes to get Java Island\'s inflation rate prediction to determine better policy on controlling cost of goods and services.•Best model using GSTARIMA methods is GSTARMA(1,1) with distance invese matrix that indicate that coordinate point of each location increase performance of inflation rate prediction.•The result indicate GSTARIMA has better accuracy than ARIMA for inflation prediction in Java Island based on RMSE value.

    测量特定年龄,背景暴露对于生命周期流行病学研究至关重要。纵向住宅数据为累积暴露指标提供了“黄金门票”,可以增强我们对健康差异的理解。住宅历史可以链接到无数的时空数据库来表征环境,社会经济,以及一个人一生经历的政策环境。然而,在美国,由于行政登记处和自我报告的限制,获得准确的居住历史是具有挑战性的。徐等人。(美国流行病学杂志。2024;193(2):348-359)详细介绍了一种将源自LexisNexis®Accurint®的居住历史与基于威斯康星州的研究队列联系起来的方法,提供与住宅历史收集挑战的见解。研究人员必须分析从队列数据中确定居住历史所固有的选择和错误分类偏差的大小。生命周期框架可以洞悉为什么移动的频率和距离是按年龄划分的,出生队列,种族/民族认同,社会经济地位,和城市化。边缘化人群寻求经济和政治机会的历史和当代移民模式必须指导对住宅历史数据的解释。我们概述了在健康差异研究中使用居住史的方法学优先事项,包括将住宅历史数据与住宅移动的决定因素联系起来,三角测量空间暴露评估方法,并透明地量化测量误差。
    Measuring age-specific, contextual exposures is crucial for lifecourse epidemiology research. Longitudinal residential data offers a \"golden ticket\" to cumulative exposure metrics and can enhance our understanding of health disparities. Residential history can be linked to myriad spatiotemporal databases to characterize environmental, socioeconomic, and policy contexts that a person experienced throughout life. However, obtaining accurate residential history is challenging in the United States due to the limitations of administrative registries and self-reports. Xu et al. (Am J Epidemiol. 2024; 193(2):348-359) detail an approach to linking residential history sourced from LexisNexis ® Accurint ® to a Wisconsin-based research cohort, offering insights into challenges with residential history collection. Researchers must analyze the magnitude of selection and misclassification biases inherent to ascertaining residential history from cohort data. A lifecourse framework can provide insights into why the frequency and distance of moves is patterned by age, birth cohort, racial/ethnic identity, socioeconomic status, and urbanicity. Historic and contemporary migration patterns of marginalized people seeking economic and political opportunities must guide interpretations of residential history data. We outline methodologic priorities for use of residential history in health disparities research, including contextualizing residential history data with determinants of residential moves, triangulating spatial exposure assessment methods, and transparently quantifying measurement error.

    背景:协调的护理系统有助于为疑似急性中风提供及时的治疗。在安大略省西北部(NWO),加拿大,社区分布广泛,几家医院提供各种诊断设备和服务。因此,资源有限,医疗保健提供者必须经常将中风患者转移到不同的医院,以确保在建议的时间范围内获得最适当的护理。然而,经常位于NWO的临时(locum)或在安大略省其他地区远程提供护理的医疗保健提供者可能在该地区缺乏足够的信息和经验,无法为具有时间敏感性的患者提供护理。次优决策可能会导致在获得明确的中风护理之前进行多次转移,导致不良结果和额外的医疗保健系统成本。
    目的:我们旨在开发一种工具来告知和协助NWO医疗保健提供者确定中风患者的最佳转移选择,以提供最有效的护理服务。我们旨在使用基于机器学习算法的综合地理映射导航和估计系统开发应用程序。这个应用程序使用与中风相关的关键时间线,包括患者最后一次被认为是好的,患者位置,治疗方案,以及不同医疗机构的成像可用性。
    方法:使用历史数据(2008-2020年),开发了一种使用机器学习方法的准确预测模型,并将其集成到移动应用程序中。这些数据包含有关空中(Ornge)和陆地医疗运输(3种服务)的参数,经过预处理和清洁。对于Ornge航空服务和陆地救护车医疗运输都涉及患者运输过程的情况,合并数据并确定运输旅程的时间间隔。数据被分发用于训练(35%),测试(35%),并对预测模型进行验证(30%)。
    结果:总计,从Ornge和陆地医疗运输服务的数据集中收集了70,623条记录,以开发预测模型。分析了各种学习模型;在预测输出变量方面,所有学习模型的性能均优于所有点的简单平均值。决策树模型提供了比其他模型更准确的结果。决策树模型表现非常好,根据测试的值,验证,和近距离内的模型。该模型用于开发“NWO导航中风”系统。该系统提供了准确的结果,并证明了移动应用程序可以成为医疗保健提供者在NWO中导航中风护理的重要工具,可能影响患者护理和结果。
    结论:NWO导航中风系统使用数据驱动,可靠,准确的预测模型,同时考虑所有变化,并同时与所有必需的急性卒中管理途径和工具相关联。使用历史数据进行了测试,下一步将涉及最终用户的可用性测试。
    BACKGROUND: A coordinated care system helps provide timely access to treatment for suspected acute stroke. In Northwestern Ontario (NWO), Canada, communities are widespread with several hospitals offering various diagnostic equipment and services. Thus, resources are limited, and health care providers must often transfer patients with stroke to different hospital locations to ensure the most appropriate care access within recommended time frames. However, health care providers frequently situated temporarily (locum) in NWO or providing care remotely from other areas of Ontario may lack sufficient information and experience in the region to access care for a patient with a time-sensitive condition. Suboptimal decision-making may lead to multiple transfers before definitive stroke care is obtained, resulting in poor outcomes and additional health care system costs.
    OBJECTIVE: We aimed to develop a tool to inform and assist NWO health care providers in determining the best transfer options for patients with stroke to provide the most efficient care access. We aimed to develop an app using a comprehensive geomapping navigation and estimation system based on machine learning algorithms. This app uses key stroke-related timelines including the last time the patient was known to be well, patient location, treatment options, and imaging availability at different health care facilities.
    METHODS: Using historical data (2008-2020), an accurate prediction model using machine learning methods was developed and incorporated into a mobile app. These data contained parameters regarding air (Ornge) and land medical transport (3 services), which were preprocessed and cleaned. For cases in which Ornge air services and land ambulance medical transport were both involved in a patient transport process, data were merged and time intervals of the transport journey were determined. The data were distributed for training (35%), testing (35%), and validation (30%) of the prediction model.
    RESULTS: In total, 70,623 records were collected in the data set from Ornge and land medical transport services to develop a prediction model. Various learning models were analyzed; all learning models perform better than the simple average of all points in predicting output variables. The decision tree model provided more accurate results than the other models. The decision tree model performed remarkably well, with the values from testing, validation, and the model within a close range. This model was used to develop the \"NWO Navigate Stroke\" system. The system provides accurate results and demonstrates that a mobile app can be a significant tool for health care providers navigating stroke care in NWO, potentially impacting patient care and outcomes.
    CONCLUSIONS: The NWO Navigate Stroke system uses a data-driven, reliable, accurate prediction model while considering all variations and is simultaneously linked to all required acute stroke management pathways and tools. It was tested using historical data, and the next step will to involve usability testing with end users.

    视觉工作记忆内容通常被认为是由刺激信息的精确视觉表示(例如,颜色,形状)。然而,先前的研究表明,个人以不同的格式表示这种视觉信息,历史上分为“口头”和“视觉”格式。随着越来越多的泛音知识,或者没有感觉的心理意象,最近的研究表明,在视觉工作记忆任务中,患有阿凡特症的个体的表现与具有典型图像的个体相似。这表明使用非视觉策略可能足以执行视觉工作记忆任务,以前被认为是严格的视觉。为了研究视觉工作记忆任务中不同策略对性能的影响,我们在视觉图像光谱中招募了个人,并测试了他们识别相对较小(3°)的能力,中等(6°),或在工作记忆中保持的光栅的取向程度发生较大(10°)变化。随后,参与者指出了他们使用五种不同策略的程度:视觉,空间,口头,语义,和感觉运动。结果表明,在所有任务难度级别上,具有幻象和典型图像的个体的表现相似。具有典型图像的个人主要使用视觉空间策略,但令人惊讶的是,与言语策略相比,具有泛音的个体绝大多数更喜欢使用非视觉空间和感觉运动策略。这些结果表明,在视觉工作记忆任务中可以采用非视觉空间和感觉运动策略,并且这些策略与视觉空间策略同样有效。这要求重新思考“视觉”与“口头”的二分法,并为在工作记忆任务中使用其他非视觉心理表征提供了证据。
    Visual working memory content is commonly thought to be composed of a precise visual representation of stimulus information (e.g., color, shape). Nevertheless, previous research has shown that individuals represent this visual information in different formats, historically dichotomized into \"verbal\" and \"visual\" formats. With growing popular knowledge of aphantasia, or the absence of sensory mental imagery, recent studies have demonstrated that individuals with aphantasia perform similarly to individuals with typical imagery on visual working memory tasks. This suggest that the use of non-visual strategies may be sufficient to perform visual working memory tasks, which were previously thought to be strictly visual. To investigate the effects of different strategies on performance in a visual working memory task, we recruited individuals across the visual imagery spectrum and tested their ability to identify relatively small (3°), medium (6°), or large (10°) changes in the degree of orientation of gratings held in working memory. Subsequently, participants indicated the extent to which they used five different strategies: visual, spatial, verbal, semantic, and sensorimotor. Results revealed that individuals with aphantasia and typical imagery performed similarly to each other across all task difficulty levels. Individuals with typical imagery dominantly used visuospatial strategies, but surprisingly, individuals with aphantasia overwhelmingly preferred the use of non-visual spatial and sensorimotor strategies over verbal strategies. These results suggest that non-visual spatial and sensorimotor strategies can be adopted in visual working memory tasks and these strategies are equally effective as visuospatial strategies. This calls for a rethinking of the \"visual\" versus \"verbal\" dichotomy, and provides evidence for the use of other non-visual mental representations in working memory tasks.
