    该数据集由COSTAction19112WomenontheMove(WEMov)开发,它致力于揭示女性移民在欧洲建设中的存在和参与。该数据集被建立为欧洲政治和公共景观中的地名和古迹的登记册-例如街道名称,学校名称和公园,以及雕像和纪念碑-庆祝女性移民。通过该数据集,我们希望发现女性移民是如何被记住的,以及这些出于各种原因经历过移民事件的人是什么样的地标。此外,我们的目标是通过在我们的网站上的交互式地图中呈现数据集的结果,使这些地标和女性移民的故事可见。此刻,该数据集包括1000个地标。数据收集基于来自40多个欧洲国家的学者和学生的志愿工作。我们的目标是广泛的地理覆盖范围;然而,由于数据收集的性质,一些领域比其他领域表现得更好。数据的收集是一个持续的过程,因此Nakala存储库中的数据集,本数据说明所指的是,展示了2023年7月的情况。数据集的更新版本将在Nakala提供,我们将定期将新的地标下载到我们的交互式地图上。选定的地标和移民轨迹具有跨社区或跨文化移民的特点。它们显示了典型和特殊的流动性形式,并呈现了不同年龄的女性,职业,社会地位和移民地位。项目和数据集的这种交叉性不仅突出了这些地标的丰富性及其学术价值,还突出了移民妇女的广泛范围及其对社会的贡献。
    数据集显示了移民妇女记忆中的地标。这些地标是历史上为纪念这些妇女而做出的政治决定的结果。地标是有形的,计价的,在公共空间,如建筑物,街道,公园,纪念碑或墓碑.这些数据集显示了所有这些地标如何在日常生活中保持对这些移民妇女的记忆。在数据集中,我们有来自欧洲各地的1000个地标。您可以在我们的网站上查看它们。
    This dataset was developed by COST Action 19112 Women on the Move (WEMov), which engages in unveiling women migrants\' presence and participation in the construction of Europe. The dataset was built as a register of toponyms and monuments in the political and public landscape in Europe - such as street names, school names and parks, as well as statues and memorials - that celebrate women migrants. With the dataset we want to discover how women migrants are remembered and what kind of landmarks present these individuals who have had an episode of migration for a variety of reasons. Moreover, our aim is to make these landmarks and the stories of women migrants visible by presenting the results of the dataset in an interactive map on our website. At the moment, the dataset includes 1000 landmarks. The collection of data was based on voluntary work of scholars and students from over 40 different European countries. We have aimed for broad geographical coverage; however, some areas are better represented than others due the nature of data collection. The collection of data is an ongoing process and therefore the dataset in Nakala repository, to which this data note refers, presents the situation in July 2023. Updated versions of the dataset will be made available in Nakala and we will download new landmarks to our interactive map on a regular basis. The selected landmarks and migrant trajectories feature cross-community or cross-cultural migration. They show both typical and exceptional forms of mobility and present women of different age, profession, social status and migration status. This intersectionality of the project and the dataset highlights not only the richness of these landmarks and their value for scholarship but also the wide spectrum of migrant women and their contribution to society.
    The dataset shows landmarks in memory of migrant women. These landmarks are the result of political decisions at one point in history to honour these women. The landmarks are tangible and denominated, available in the public space, such as buildings, streets, parks, monuments or gravestones. This collection of data shows how all these landmarks keep the memory of these migrant women alive in daily life. In the dataset we have 1000 landmarks from all over Europe. You can view them on our website.

    心房颤动(AF)引发心房重构,影响心房功能和消融疗效。这种重塑导致心房心肌病和扩张,与二尖瓣反流有关,形成心房功能性二尖瓣反流(aFMR)。我们的研究探讨了早期aFMR与心房电结构之间的关系,关注房颤患者的左心房双极电压和低电压区(LVA)。
    我们招募了282例房颤复发后PVI患者。消融前进行超声心动图检查,只有没有的病人,温和,纳入或轻度至中度aFMR。消融使用射频和3D映射系统,每个心房壁上记录心房电压。LVAs是使用高密度地图计算的,患者随访15个月。
    根据aFMR严重程度观察到左心房电压和LVA程度的显著差异。与无aFMR相比,aFMR1+患者的心房电压明显降低,但LVAs没有显著增加。与非aFMR患者相比,aFMR2+患者在所有心房区域显示出较低的电压幅度和较大的LVAs。aFMR组房颤复发率明显更高(62.9%vs.48.3%,p=0.027)在1年内。aFMR与调整性别后房颤复发相关,年龄,和房颤类型(HR:1.517,95%CI:1.057-2.184,p=0.025)。
    房颤患者的aFMR可能提示进行性心房重构和左心房心肌病,以心房电压降低和LVAs增加为特征。aFMR与PVI结果有关,建议在房颤治疗决策中考虑。
    UNASSIGNED: Atrial fibrillation (AF) triggers atrial remodeling, impacting atrial function and ablation efficacy. This remodeling leads to atrial cardiomyopathy and dilatation, linked to mitral regurgitation, forming atrial functional mitral regurgitation (aFMR). Our study explores the relationship between early-stage-aFMR and the atrial electrical architecture, focusing on left atrial bipolar voltage and low-voltage areas (LVAs) in AF patients.
    UNASSIGNED: We enrolled 282 patients undergoing redo-PVI after AF recurrence post-PVI. Echocardiography was performed prior to ablation, and only patients with no, mild, or mild-to-moderate aFMR were included. Ablation used radiofrequency and a 3D mapping system, with atrial voltage documented on each atrial wall. LVAs were calculated using high-density maps, and patients were followed for 15 months.
    UNASSIGNED: Significant differences in left atrial voltage and LVA extent were observed based on aFMR severity. Patients with aFMR 1 + had significantly lower atrial voltage compared to no-aFMR, but no significant increase in LVAs. Patients with aFMR 2 + showed lower voltage amplitudes in all atrial regions and larger LVAs compared to no-aFMR patients. AF recurrence was significantly higher in the aFMR group (62.9% vs. 48.3%, p = 0.027) within 1 year. aFMR was associated with AF recurrence after adjusting for sex, age, and AF types (HR: 1.517, 95% CI: 1.057-2.184, p = 0.025).
    UNASSIGNED: aFMR in AF patients may indicate progressive atrial remodeling and left atrial cardiomyopathy, characterized by reduced atrial voltage and increased LVAs. aFMR is linked to PVI outcomes, suggesting its consideration in AF therapy decision-making.

    钩端螺旋体病是全世界猪中的广泛感染。在乌克兰的大多数情况下,只有显微镜凝集试验(MAT)用于动物钩端螺旋体病的诊断。总的来说,2001-2019年期间,我国检测了2.381.163份猪血清,收到85.338份阳性反应,即3.58%[二项式置信区间(BCI),3.56-3.61%]。已确定血清型coppenheni-33.91%(BCI,33.59-34.23%),布拉迪斯拉发-14.14%(BCI,13.90-14.37%),波莫纳-8.58%(BCI,8.39-8.77%),塔拉索维-7.12%(BCI,6.95-7.30%)在猪钩端螺旋体病的病因结构中起主导作用。观察到对几种血清型的大量阳性反应-阳性病例总数的29.78%(BCI,29.47-30.09%)。此外,本文根据对乌克兰猪中循环的8种血清变型的回顾性分析提供了数据。因此,在十九年期间,对布拉迪斯拉发的阳性反应数量有所减少,波莫纳,和tarassovi以及对coppenheni的阳性反应数量的增加,Polonica,还有kabura.进行了乌克兰境内猪钩端螺旋体病的测绘。这允许人们在猪中识别具有钩端螺旋体病感染风险的区域。地图显示,乌克兰东部和中部的发病率最高。
    Leptospirosis is a widespread infection among pigs throughout the world. In most cases in Ukraine, only the microscopic agglutination test (MAT) is used for the diagnosis of leptospirosis in animals. In general, during the period of 2001-2019, 2 381 163 samples of blood sera from swine were tested in our country and 85 338 positive reactions were received, which is 3.58% [binomial confidence intervals (BCI), 3.56-3.61%]. It was established that the serovars copenhageni - 33.91% (BCI, 33.59-34.23%), bratislava - 14.14% (BCI, 13.90-14.37%), pomona - 8.58% (BCI, 8.39-8.77%), and tarassovi - 7.12% (BCI, 6.95-7.30%) play a leading role in the aetiological structure of swine leptospirosis. A large number of positive reactions to several serovars was observed - 29.78% (BCI, 29.47-30.09%) of the total number of positive cases. In addition, the article presents data according to a retrospective analysis of the eight serovars circulating among pigs in Ukraine. Thus, during the nineteen year period, there was a decrease in the number of positive reactions to bratislava, pomona, and tarassovi and an increase in the number of positive reactions to copenhageni, polonica, and kabura. Mapping Ukraine\'s territory for leptospirosis among pigs was carried out. This allows one to identify zones with a risk of leptospirosis infections among swine. The maps show that the highest incidence rates were identified in the eastern and central parts of Ukraine.

    背景:健康相关生活质量(HRQL)已成为心脏病学的重要结果参数。MOS36-Item简式健康调查(SF-36)和PROMIS-29是两种广泛使用的通用指标,可提供综合HRQL评分。SF-36是一种使用了几十年的成熟仪器,可以汇总为身体(PCS)和心理(MCS)组件汇总分数。还提出了用于相关分量得分(PCSc和MCSc)的替代评分算法。PROMIS-29是一种较新但越来越多地使用的HRQL措施。类似于SF-36,身体和心理健康总结得分可以从PROMIS-29领域得分得出,基于相关因子解。到目前为止,PROMIS-29的分数不能直接与SF-36的结果相当,使研究结果的汇总复杂化。因此,我们的目标是提供将PROMIS-29数据转换为完善的SF-36分量汇总分数的算法.
    方法:来自柏林血管事件长期观察(BeLOVE)研究的n=662名参与者的数据用于估计线性回归模型,其中PROMIS-29领域得分或汇总的PROMIS-29身体/心理健康汇总得分作为预测因子,SF-36身体/心理成分汇总得分作为结果。来自随后的评估点(n=259)的数据用于评估经验和预测的SF-36评分之间的一致性。
    结果:PROMIS-29领域得分以及PROMIS-29健康总结得分对PCS显示出较高的预测价值,PCSc,和MCSc(R2≥70%),和MCS的中等预测值(R2=57%,R2=40%,分别)。将回归系数应用于新数据后,大多数模型的经验和预测的SF-36分量汇总得分高度相关(r>0.8).经验分数和预测分数之间的平均差异可以忽略不计(|SMD|<0.1)。
    结论:这项研究提供了易于应用的算法,可以将PROMIS-29数据转换为心血管人群中完善的SF-36身体和心理成分汇总得分。应用于新数据,经验和预测的SF-36分数之间的一致性很高.然而,对于SF-36心理成分汇总分数,与原始因子模型(MCS)相比,在相关模型(MCSc)下发现的预测要好得多。此外,作为相关的副产品,我们的研究证实了在心脏病患者中相对较新的PROMIS-29健康总结评分的结构效度.
    BACKGROUND: Health-related quality of life (HRQL) has become an important outcome parameter in cardiology. The MOS 36-ltem Short-Form Health Survey (SF-36) and the PROMIS-29 are two widely used generic measures providing composite HRQL scores. The domains of the SF-36, a well-established instrument utilized for several decades, can be aggregated to physical (PCS) and mental (MCS) component summary scores. Alternative scoring algorithms for correlated component scores (PCSc and MCSc) have also been suggested. The PROMIS-29 is a newer but increasingly used HRQL measure. Analogous to the SF-36, physical and mental health summary scores can be derived from PROMIS-29 domain scores, based on a correlated factor solution. So far, scores from the PROMIS-29 are not directly comparable to SF-36 results, complicating the aggregation of research findings. Thus, our aim was to provide algorithms to convert PROMIS-29 data to well-established SF-36 component summary scores.
    METHODS: Data from n = 662 participants of the Berlin Long-term Observation of Vascular Events (BeLOVE) study were used to estimate linear regression models with either PROMIS-29 domain scores or aggregated PROMIS-29 physical/mental health summary scores as predictors and SF-36 physical/mental component summary scores as outcomes. Data from a subsequent assessment point (n = 259) were used to evaluate the agreement between empirical and predicted SF-36 scores.
    RESULTS: PROMIS-29 domain scores as well as PROMIS-29 health summary scores showed high predictive value for PCS, PCSc, and MCSc (R2 ≥ 70%), and moderate predictive value for MCS (R2 = 57% and R2 = 40%, respectively). After applying the regression coefficients to new data, empirical and predicted SF-36 component summary scores were highly correlated (r > 0.8) for most models. Mean differences between empirical and predicted scores were negligible (|SMD|<0.1).
    CONCLUSIONS: This study provides easy-to-apply algorithms to convert PROMIS-29 data to well-established SF-36 physical and mental component summary scores in a cardiovascular population. Applied to new data, the agreement between empirical and predicted SF-36 scores was high. However, for SF-36 mental component summary scores, considerably better predictions were found under the correlated (MCSc) than under the original factor model (MCS). Additionally, as a pertinent byproduct, our study confirmed construct validity of the relatively new PROMIS-29 health summary scores in cardiology patients.

    开发一种基于深度学习的模型,该模型能够在来自心脏MRI的原始T1图上沿长轴和短轴方向分割左心室(LV)心肌。使用手动分割作为参考标准,对来自50名健康志愿者和75名患者的天然心肌T1图进行了模型训练。基于U-Net架构,我们使用两种不同的训练指标(Sørensen-Dice系数=DSC和Intersection-over-Union=IOU)系统地优化了模型设计,两个不同的激活函数(ReLU和LeakyReLU)和不同数量的训练时期。使用DSC度量和ReLU激活函数在35个时期内进行的训练取得了最高的整体性能(T110.6±17.9ms的平均误差,平均DSC0.88±0.07)。模型结果与地面实况之间的一致性极限为-35.5至36.1ms。这优于两个人类评估者之间的协议(-34.7至59.1ms)。对于长轴视图,分割同样准确(平均误差T1:6.77±8.3ms,平均DSC:0.89±0.03),对于短轴图像(平均误差ΔT1:11.6±19.7ms,平均DSC:0.88±0.08)。可以在长轴和短轴方向上以非常高的精度对天然心肌T1图进行全自动分割和定量分析。
    To develop a deep learning-based model capable of segmenting the left ventricular (LV) myocardium on native T1 maps from cardiac MRI in both long-axis and short-axis orientations. Models were trained on native myocardial T1 maps from 50 healthy volunteers and 75 patients using manual segmentation as the reference standard. Based on a U-Net architecture, we systematically optimized the model design using two different training metrics (Sørensen-Dice coefficient = DSC and Intersection-over-Union = IOU), two different activation functions (ReLU and LeakyReLU) and various numbers of training epochs. Training with DSC metric and a ReLU activation function over 35 epochs achieved the highest overall performance (mean error in T1 10.6 ± 17.9 ms, mean DSC 0.88 ± 0.07). Limits of agreement between model results and ground truth were from -35.5 to + 36.1 ms. This was superior to the agreement between two human raters (-34.7 to + 59.1 ms). Segmentation was as accurate for long-axis views (mean error T1: 6.77 ± 8.3 ms, mean DSC: 0.89 ± 0.03) as for short-axis images (mean error ΔT1: 11.6 ± 19.7 ms, mean DSC: 0.88 ± 0.08). Fully automated segmentation and quantitative analysis of native myocardial T1 maps is possible in both long-axis and short-axis orientations with very high accuracy.

    背景:检测葡萄糖-6-磷酸脱氢酶(G6PD)缺乏症是治疗疟疾的重要考虑因素。G6PD缺乏可能导致疟疾治疗期间的溶血性贫血,因此,确定G6PD缺乏症在疟疾治疗策略中非常重要。
    方法:本报告提供了范围审查的结果以及证据和差距图,供G6PD近患者试验指南开发小组考虑,以支持间日疟原虫的根治。本范围审查调查了G6PD缺乏症的常见诊断测试以及决策的重要背景和其他因素。这些因素包括世界卫生组织(世卫组织)指南制定手册建议的六个考虑因素,这些因素对确定建议的方向和力度很重要,并包括“可接受性”,\'可行性,\'\'权益,结果的\'\'估值,\'\'性别\'和\'人权\'。本范围审查的目的是为未来的系统审查和证据综合提供指导,这可以更好地为制定世卫组织关于将G6PD缺乏症检测作为疟疾治疗战略一部分的建议提供信息。
    结果:进行了全面搜索,包括出版,任何文章的同行评审文献,研究G6PD诊断测试和“可接受性”因素的任何研究设计和方法,\'可行性,\'\'权益,结果的\'\'估值,\'\'性别\'和\'人权\'。从搜索中确定了1152项研究,其中14人被确定有资格纳入本次审查。这些研究包含来自21个独特国家的数据,这些国家将G6PD诊断测试视为疟疾治疗策略的一部分。上下文和附加因素之间的关系,G6PD缺乏症的诊断测试和研究方法在总体证据和差距中提出,这表明大多数证据是诊断测试的背景因素,和标准G6PD(SD生物传感器)测试。
    结论:本范围审查产生了动态证据和差距图,对G6PD诊断测试领域内的新兴证据具有反应性。证据和差距图提供了所有可用文献的全面描述,这些文献涉及对决策重要的背景和其他因素,关于特定的G6PD诊断测试。调查感兴趣的背景因素的大多数可用数据与定量G6PD诊断测试有关。虽然可以对这些数据进行正式的定性综合,作为系统审查的一部分,数据可能太异,这是不合适的。这些结果现在可用于为世卫组织G6PD指导发展小组的未来方向提供信息,以支持间日疟原虫的根治。
    BACKGROUND: Testing for glucose-6-phosphate dehydrogenase (G6PD) deficiency is an important consideration regarding treatment for malaria. G6PD deficiency may lead to haemolytic anaemia during malaria treatment and, therefore, determining G6PD deficiency in malaria treatment strategies is extremely important.
    METHODS: This report presents the results of a scoping review and evidence and gap map for consideration by the Guideline Development Group for G6PD near patient tests to support radical cure of Plasmodium vivax. This scoping review has investigated common diagnostic tests for G6PD deficiency and important contextual and additional factors for decision-making. These factors include six of the considerations recommended by the World Health Organization (WHO) handbook for guideline development as important to determining the direction and strength of a recommendation, and included \'acceptability\', \'feasibility,\' \'equity,\' \'valuation of outcomes,\' \'gender\' and \'human rights\'. The aim of this scoping review is to inform the direction of future systematic reviews and evidence syntheses, which can then better inform the development of WHO recommendations regarding the use of G6PD deficiency testing as part of malaria treatment strategies.
    RESULTS: A comprehensive search was performed, including published, peer-reviewed literature for any article, of any study design and methodology that investigated G6PD diagnostic tests and the factors of \'acceptability\', \'feasibility,\' \'equity,\' \'valuation of outcomes,\' \'gender\' and \'human rights\'. There were 1152 studies identified from the search, of which 14 were determined to be eligible for inclusion into this review. The studies contained data from over 21 unique countries that had considered G6PD diagnostic testing as part of a malaria treatment strategy. The relationship between contextual and additional factors, diagnostic tests for G6PD deficiency and study methodology is presented in an overall evidence and gap, which showed that majority of the evidence was for the contextual factors for diagnostic tests, and the \'Standard G6PD (SD Biosensor)\' test.
    CONCLUSIONS: This scoping review has produced a dynamic evidence and gap map that is reactive to emerging evidence within the field of G6PD diagnostic testing. The evidence and gap map has provided a comprehensive depiction of all the available literature that address the contextual and additional factors important for decision-making, regarding specific G6PD diagnostic tests. The majority of data available investigating the contextual factors of interest relates to quantitative G6PD diagnostic tests. While a formal qualitative synthesis of this data as part of a systematic review is possible, the data may be too heterogenous for this to be appropriate. These results can now be used to inform future direction of WHO Guideline Development Groups for G6PD near patient tests to support radical cure of P. vivax malaria.

    背景:基于偏好的健康相关生活质量(HRQoL)测量,例如EQ-5D或SF-6D,对卫生经济评价至关重要。然而,它们很少被纳入强直性脊柱炎(AS)的临床试验.这项研究旨在开发映射算法,以根据巴斯强直性疾病活动指数(BASDAI)和巴斯强直性脊柱炎功能指数(BASFI)预测EQ-5D-3L和EQ-5D-5L健康效用得分。
    方法:从山东省最大的三级医院招募AS患者,中国,2019年12月至2020年10月。采用方便抽样法根据以下标准选择患者:(1)符合纽约标准诊断为AS;(2)年龄18岁及以上;(3)无精神障碍;(4)能够理解问卷;(5)无严重并发症。有243名患者完成了面对面的问卷调查,排除5例关键变量缺失值的病例。普通最小二乘,审查最小绝对偏差,Tobit,直接方法中的调整有限因变量混合模型和β混合模型(BM)以及响应方法中的有序logit和多项式logit(Mlogit)模型用于开发映射算法。平均绝对误差,均方根误差,使用Spearman相关系数和一致性相关系数来获得预测性能。
    结果:238例AS患者的平均年龄为35.19(SD=9.59)岁,男性占多数(74.47%)。观察到的EQ-5D-3L和EQ-5D-5L健康效用值分别为0.88(SD=0.12)和0.74(SD=0.27),分别。EQ-5D-5L与BASDAI和BASFI的概念重叠高于EQ-5D-3L。Mlogit是EQ-5D-3L性能最好的型号,BM在预测EQ-5D-5L方面表现出比其他直接和间接映射模型更好的性能。
    结论:这项研究表明,EQ-5D-5L,而不是EQ-5D-3L,应选择作为中国AS患者HRQoL的目标结局指标,BM映射算法可用于预测BASDAI和BASFI的EQ-5D-5L值,以进行卫生经济学评价。
    BACKGROUND: Preference-based measures of health-related quality of life (HRQoL), such as the EQ-5D or the SF-6D, are essential for health economic evaluation. However, they are rarely included in clinical trials of ankylosing spondylitis (AS). This study aims to develop mapping algorithms to predict EQ-5D-3L and EQ-5D-5L health utility scores from the Bath Ankylosing Disease Activity Index (BASDAI) and the Bath Ankylosing Spondylitis Functional Index (BASFI).
    METHODS: Patients with AS were recruited from the largest tertiary hospital in Shandong province, China, between December 2019 and October 2020. Patients were selected by convenience sampling method according to the following criteria: (1) diagnosed with AS according to the New York criteria; (2) aged 18 years and above; and (3) without mental disorders; (4) able to understand the questionnaires; (5) without serious complications. There were 243 patients who completed the face-to-face questionnaire survey, and 5 cases with missing values in key variables were excluded. Ordinary least squares, censored least absolute deviations, Tobit, adjusted limited dependent variable mixture model and beta-mixture model (BM) in the direct approach and ordered logit and multinomial logit (Mlogit) model in the response approach were used to develop mapping algorithms. Mean absolute error, root mean square error, Spearman\'s correlation coefficient and concordance correlation coefficient were used to access predictive performance.
    RESULTS: The 238 patients with AS had a mean age of 35.19 (SD = 9.59) years, and the majority (74.47%) were male. The observed EQ-5D-3L and EQ-5D-5L health utility values were 0.88 (SD = 0.12) and 0.74 (SD = 0.27), respectively. The EQ-5D-5L had higher conceptual overlap with the BASDAI and BASFI than the EQ-5D-3L did. The Mlogit was the best-performing model for the EQ-5D-3L, and the BM showed better performance in predicting EQ-5D-5L than other direct and indirect mapping models did.
    CONCLUSIONS: This study demonstrates that the EQ-5D-5L, rather than EQ-5D-3L, should be selected as the target outcome measure of HRQoL in patients with AS in China, and the BM mapping algorithm could be used to predict EQ-5D-5L values from BASDAI and BASFI for health economic evaluation.

    背景:口服阿立哌唑在抑制患有抽动障碍的儿童和青少年抽动方面具有良好的临床疗效和安全性。本研究旨在从中国医疗系统的角度评估和比较高剂量和低剂量阿立哌唑在儿童和青少年抽动障碍中的成本效益。
    方法:对146例抽动障碍患者进行问卷调查,其中144人完成了EQ-5D-Y和YGTSS。使用两种映射算法,建立了四个模型将YGTSS转换为EQ-5D-Y实用程序。我们构建了包含疗效和安全性的决策树模型,以根据我们的映射函数比较高剂量和低剂量阿立哌唑的成本效益。
    结果:在我们的决策树模型中选择了具有模型1(YGTSS总评分)的GLM作为首选函数。基本病例成本-效果分析表明,与低剂量阿立哌唑相比,大剂量阿立哌唑可提高0.001QALYs的有效性,并增加197.99美元的总成本,导致每QALY的ICER为174339.22美元,超过人均国内生产总值的三倍。因此,对于患有抽动障碍的儿童患者,大剂量阿立哌唑不太可能是一种具有成本效益的选择.单因素敏感性分析和概率敏感性分析表明,这些结果是稳健的。
    结论:根据现有数据,低剂量阿立哌唑可能是安全的,有效,和儿童和青少年抽动障碍的经济剂量。
    结论:我们研究的主要局限性是缺乏直接用于成本效益分析的效用。我们通过映射函数间接获得了抽动障碍患者的效用。这可能会引入一些偏见和不确定性。在我们的模型中使用德国的直接医疗费用是一个限制。尽管我们使用购买力平价将其转换为中国的等值,在解释本研究结果时应谨慎行事。
    BACKGROUND: Oral aripiprazole exhibits favorable clinical efficacy and safety in the suppression of tics in children and adolescents with tic disorders. This study aims to evaluate and compare the cost-effectiveness of high-dose and low-dose aripiprazole in children and adolescents with tic disorders from the perspective of the Chinese healthcare system.
    METHODS: A questionnaire survey was conducted on 146 patients with tic disorders, of whom 144 completed EQ-5D-Y and YGTSS. Four models were built to convert YGTSS onto EQ-5D-Y utility using two mapping algorithms. We constructed a decision tree model containing efficacy and safety to compare the cost-effectiveness of high-dose and low-dose aripiprazole based on our mapping function.
    RESULTS: The GLM with model 1 (YGTSS total tic scores) was selected as the preferred function in our decision tree model. The base case cost-effectiveness analysis showed that compared to low-dose aripiprazole, high-dose aripiprazole improves effectiveness by 0.001QALYs and increases the overall cost by $197.99, resulting in an ICER of $174339.22 per QALY, which exceeds three times the gross domestic product per capita. Hence, high-dose aripiprazole is not likely to be a cost-effective option for child patients with tic disorders. One-way sensitivity analysis and probabilistic sensitivity analysis showed that these results is robust.
    CONCLUSIONS: On the basis of currently available data, low-dose aripiprazole may be a safe, effective, and economical dosage for children and adolescents with tic disorders.
    CONCLUSIONS: The main limitation of our study is the lack of utility directly used for cost-effectiveness analysis. We obtained the utility of patients with tic disorders indirectly by the mapping function. This may introduce some bias and uncertainty. And it is a limitation to use the direct medical costs of Germany in our model. Although we converted it to the equivalent value of China using purchasing power parities, caution should be exercised when interpreting the results of this study.

    大麦条纹或黄色锈病(BYR)由条锈病引起。大麦(Psh)是大麦生产的重要制约因素。这种疾病最好通过遗传抗性来控制,这被认为是综合疾病管理中最经济和可持续的组成部分。在这项研究中,我们评估了多种疾病环境下一组国际大麦基因型(n=266)对Psh的抗性多样性(厄瓜多尔,印度,和墨西哥)使用全基因组关联研究(GWAS)。确定了与Psh抗性相关的四个数量性状基因座(QTL)(三个在1H染色体上,一个在7H染色体上)。通过在五个双亲群体中绘制对Psh的抗性来验证QTL,它检测到染色体1H上的关键基因组区域(种群Pompadour/Zhoungdamei,Pompadour/Zug161,和CI9214/Baudin),3H(里卡多/格斯),和7H(Fumai8/Baronesse)。RpshQ的QTL。GWAS和RpshQ检测到GWA.1H.1。使用双亲定位种群检测到的Bau.1H在整个环境中最一致和稳定,并且可能是相同的抗性区域。RpshQ.通过富集目标区域,使用populationCI9214/Baudin饱和Bau.1H,在Morex参考基因组v.2中,将抗性基因座置于7.9和8.1Mbp之间(侧翼为标记sun_B1H_03,靠近Rpsh_1H和sun_B1H_KASP_02的0.7cM,在1HS的远端3.2cM)。竞争性等位基因特异性PCR(KASP)标记sun_B1H_KASP_01共分离用于RpshQ。开发了Bau.1H。该标记在50个澳大利亚大麦品种上得到了验证,在六种基因型中显示出明确的等位基因区分和存在(Baudin,Fathom,旗舰,灌浆,Sakurastar,和Shepherd)。该标记可用于可靠的标记辅助选择和Psh抗性的金字塔化,并使抗条锈病的遗传基础多样化。
    Barley stripe or yellow rust (BYR) caused by Puccinia striiformis f. sp. hordei (Psh) is a significant constraint to barley production. The disease is best controlled by genetic resistance, which is considered the most economical and sustainable component of integrated disease management. In this study, we assessed the diversity of resistance to Psh in a panel of international barley genotypes (n = 266) under multiple disease environments (Ecuador, India, and Mexico) using genome-wide association studies (GWASs). Four quantitative trait loci (QTLs) (three on chromosome 1H and one on 7H) associated with resistance to Psh were identified. The QTLs were validated by mapping resistance to Psh in five biparental populations, which detected key genomic regions on chromosomes 1H (populations Pompadour/Zhoungdamei, Pompadour/Zug161, and CI9214/Baudin), 3H (Ricardo/Gus), and 7H (Fumai8/Baronesse). The QTL RpshQ.GWA.1H.1 detected by GWAS and RpshQ.Bau.1H detected using biparental mapping populations co-located were the most consistent and stable across environments and are likely the same resistance region. RpshQ.Bau.1H was saturated using population CI9214/Baudin by enriching the target region, which placed the resistance locus between 7.9 and 8.1 Mbp (flanked by markers sun_B1H_03, 0.7 cM proximal to Rpsh_1H and sun_B1H_KASP_02, 3.2 cM distal on 1HS) in the Morex reference genome v.2. A Kompetitive Allele Specific PCR (KASP) marker sun_B1H_KASP_01 that co-segregated for RpshQ.Bau.1H was developed. The marker was validated on 50 Australian barley cultivars, showing well-defined allelic discrimination and presence in six genotypes (Baudin, Fathom, Flagship, Grout, Sakurastar, and Shepherd). This marker can be used for reliable marker-assisted selection and pyramiding of resistance to Psh and in diversifying the genetic base of resistance to stripe rust.
