预测性分析
  • 文章类型: Journal Article
    背景:塞马鲁肽,胰高血糖素样肽1受体激动剂(GLP1RA),可用于肠胃外和口服制剂。对可注射制剂的研究令人信服地证明了其对主要不良心脏事件(MACE)的有益作用。进行此预测分析以预测SOUL试验(口服司马鲁肽)的提前终止以及主要事件。
    方法:灵魂是一个多中心,双盲,安慰剂对照随机对照试验(RCT)评价2型糖尿病(T2D)和心血管疾病(CV)患者口服司马鲁肽与安慰剂相比MACE的减少.9642名参与者的样本将被跟踪5年零5个月。随机效应模型荟萃分析,汇集以前RCT的危险比,使用R软件进行预测模型。先前使用semaglutide的RCTs的安慰剂组的背景CV事件发生率与SOUL试验的裁定前假设相匹配,以创建预测模型。截断的试验持续时间,MACE,并估计其在干预和安慰剂组中的各个组成部分。使用卡方检验估计两组之间的预测差异。
    结果:对10,013例患者的汇总分析显示,与司马鲁肽相关的MACE数量显着减少(HR0.79,95%CI0.69-0.91)。预测分析表明,到3.78年将实现1225个事件,建议过早终止。
    结论:基于荟萃分析的数学模型预测,SOUL对口服司马鲁肽的研究将提前终止,与安慰剂相比,口服司美鲁肽在MACE方面显示出益处。如果灵魂研究证实了这个模型的发现,它不仅可以构成计算功率的基础,而且可以定义此类研究的持续时间,降低成本并简化设计心血管结局试验(CVOTs)的过程。
    背景:INPLASY202460061.
    BACKGROUND: Semaglutide, a glucagon-like peptide 1 receptor agonist (GLP1RA), is available in both parenteral and oral preparations. Studies of injectable preparations have convincingly demonstrated its beneficial effect on major adverse cardiac events (MACE). This predictive analysis was undertaken to forecast early termination of the SOUL trial (oral semaglutide) as well as the primary events.
    METHODS: SOUL is a multicenter, double-blind, placebo-controlled randomized controlled trial (RCT) evaluating the reduction in MACE associated with oral semaglutide versus placebo in patients with type 2 diabetes (T2D) and cardiovascular (CV) disease. A sample of 9642 participants will be followed for 5 years and 5 months. A random-effects model meta-analysis, pooling hazard ratios from previous RCTs, was conducted using R software to inform the predictive model. The background CV event rates from the placebo arms of previous RCTs with semaglutide were matched with the pre-adjudicated assumptions of the SOUL trial to create the predictive model. The truncated trial duration, MACE, and its individual components in the intervention and placebo arms were estimated. The predicted difference between the two groups was estimated using the chi-squared test.
    RESULTS: A pooled analysis of 10,013 patients revealed a significant reduction in the number of MACEs associated with semaglutide (HR 0.79, 95% CI 0.69-0.91). Predictive analysis indicated that 1225 events would be achieved by 3.78 years, suggesting premature termination.
    CONCLUSIONS: The mathematical model based on the meta-analysis predicts that the SOUL study on oral semaglutide will be terminated early, with oral semaglutide showing benefits in terms of MACE compared to placebo. If the SOUL study corroborates the findings of this model, it may not only form the basis for the calculation of power but also define the duration of such studies, reducing costs and easing the process of designing cardiovascular outcome trials (CVOTs).

    The program code developed by others is appropriately cited in the text and listed in the references section. The raw and processed data on which study conclusions are based are not available. The statistical syntax needed to reproduce analyses in the article is available upon request. The methods section provides references for the materials described therein. We report how we determined our sample size, all data exclusions, all manipulations, and all measures in the study, and we follow APA Style Journal Article Reporting Standards. This study\'s design, hypotheses, and data analytic plan were not pre-registered. Prior research supports the need for elementary-aged students with reading difficulties (RD) to receive explicit systematic small group evidence-based reading instruction. Yet for many students, simply receiving an evidence-based reading instruction in a small group setting is insufficient to reach the progress milestones needed to meet grade level reading standards. The current study examined whether: (1) elementary school students with RD constitute a homogeneous or heterogeneous groups when considering their basic language and cognitive skills (using a latent profile analysis), and (2) if latent profiles are predictive of response to reading comprehension instruction (using a mixed modeling approach). The sample consisted of 335 students, including students with RD and typical students (n = 57). The results revealed heterogeneity within students with RD - there were two distinct profiles, with one having higher basic language (reading fluency and decoding) and cognitive (verbal domain productivity, cognitive flexibility, working memory) skills and lower attention skills, and the other having stronger attention skills and lower basic language and cognitive skills. The findings also suggested that latent profiles were predictive of response to reading comprehension instruction. Our results provide a convincing argument for leading the field in the direction of developing customized interventions. It is conceivable, but remains to be further examined, that researchers and educators could potentially improve reading outcomes through providing a customized reading intervention to a student based on their cognitive-language profile.

    人工智能(AI)和机器学习(ML)在生活的多个领域和领域取得了进步;然而,它在多组学领域的进展与其他人所达到的水平不符。挑战包括但不限于处理和分析大量复杂的多组学数据,以及实施和执行AI/ML方法所需的专业知识。在这篇文章中,我们提出了智能基因,一个互动的,可定制,跨平台,和用户友好的AI/ML应用程序,用于多组学数据探索,以发现新的生物标志物并预测稀有,普通,复杂的疾病。实施的方法是基于传统的统计技术和尖端的机器学习算法,它优于单一算法,并提高了准确性。IntelliGenes的交互式和跨平台图形用户界面分为三个主要部分:(i)数据管理器,(ii)AI/ML分析,(三)可视化。DataManager支持用户加载和自定义输入数据和现有生物标志物列表。AI/ML分析允许用户应用统计和ML算法的默认组合,以及自定义和创建新的AI/ML管道。可视化提供选项来解释一组不同的产生的结果,包括性能指标,疾病预测,和各种图表。IntelliGenes的性能已在可变的内部和同行评审研究中成功测试,并且能够正确地将个体分类为患者并以高精度预测疾病。它的区别主要在于其对非技术用户的使用简单性以及其对生成可解释的可视化的强调。我们设计和实现了IntelliGenes,无论有没有计算背景的用户都可以应用AI/ML方法来发现新的生物标志物并预测疾病。
    Artificial intelligence (AI) and machine learning (ML) have advanced in several areas and fields of life; however, its progress in the field of multi-omics is not matching the levels others have attained. Challenges include but are not limited to the handling and analysis of high volumes of complex multi-omics data, and the expertise needed to implement and execute AI/ML approaches. In this article, we present IntelliGenes, an interactive, customizable, cross-platform, and user-friendly AI/ML application for multi-omics data exploration to discover novel biomarkers and predict rare, common, and complex diseases. The implemented methodology is based on a nexus of conventional statistical techniques and cutting-edge ML algorithms, which outperforms single algorithms and result in enhanced accuracy. The interactive and cross-platform graphical user interface of IntelliGenes is divided into three main sections: (i) Data Manager, (ii) AI/ML Analysis, and (iii) Visualization. Data Manager supports the user in loading and customizing the input data and list of existing biomarkers. AI/ML Analysis allows the user to apply default combinations of statistical and ML algorithms, as well as customize and create new AI/ML pipelines. Visualization provides options to interpret a diverse set of produced results, including performance metrics, disease predictions, and various charts. The performance of IntelliGenes has been successfully tested at variable in-house and peer-reviewed studies, and was able to correctly classify individuals as patients and predict disease with high accuracy. It stands apart primarily in its simplicity in use for nontechnical users and its emphasis on generating interpretable visualizations. We have designed and implemented IntelliGenes in a way that a user with or without computational background can apply AI/ML approaches to discover novel biomarkers and predict diseases.

    我们以统一的方式对乘法双季节自回归(DSAR)模型进行了完整的贝叶斯分析,考虑识别(最佳子集选择),估计,和预测问题。我们假设DSAR模型误差是正态分布的,并为模型滞后引入潜在变量,然后我们将DSAR模型嵌入到分层贝叶斯正态混合结构中。通过对每个潜在变量采用伯努利先验,并对DSAR模型系数和方差采用正反伽马先验,分别,我们以封闭形式导出了完整的条件后验分布和预测分布。使用这些推导的条件后验和预测分布,我们通过提出Gibbs采样算法来逼近后验和预测分布,并提供多步超前预测,从而对DSAR模型进行全面的贝叶斯分析。我们使用广泛的模拟研究来评估DSAR模型的完整贝叶斯分析的效率,然后,我们将我们的工作应用于16个欧洲国家的几个实际小时电力负荷时间序列数据集。
    We present a full Bayesian analysis of multiplicative double seasonal autoregressive (DSAR) models in a unified way, considering identification (best subset selection), estimation, and prediction problems. We assume that the DSAR model errors are normally distributed and introduce latent variables for the model lags, and then we embed the DSAR model in a hierarchical Bayes normal mixture structure. By employing the Bernoulli prior for each latent variable and the mixture normal and inverse gamma priors for the DSAR model coefficients and variance, respectively, we derive the full conditional posterior and predictive distributions in closed form. Using these derived conditional posterior and predictive distributions, we present the full Bayesian analysis of DSAR models by proposing the Gibbs sampling algorithm to approximate the posterior and predictive distributions and provide multi-step-ahead predictions. We evaluate the efficiency of the proposed full Bayesian analysis of DSAR models using an extensive simulation study, and we then apply our work to several real-world hourly electricity load time series datasets in 16 European countries.

    这项研究调查了在4°C下储存的鲜切木瓜的理化和风味品质变化。采用多因素统计分析评价鲜切木瓜的新鲜度。选择有氧平板计数作为鲜切木瓜新鲜度的预测指标,利用偏最小二乘回归(PLSR)建立新鲜度预测模型,和支持向量机回归(SVMR)算法。根据理化和风味质量分析,可以很好地区分鲜切木瓜的新鲜度。有氧板计数,作为鲜切木瓜新鲜度的预测指标,与储存时间显著相关。SVMR模型比PLSR模型具有更高的预测精度。将风味品质与多元统计分析相结合,可以有效地评价鲜切木瓜的新鲜度。
    This study investigated the physicochemical and flavor quality changes in fresh-cut papaya that was stored at 4 °C. Multivariate statistical analysis was used to evaluate the freshness of fresh-cut papaya. Aerobic plate counts were selected as a predictor of freshness of fresh-cut papaya, and a prediction model for freshness was established using partial least squares regression (PLSR), and support vector machine regression (SVMR) algorithms. Freshness of fresh-cut papaya could be well distinguished based on physicochemical and flavor quality analyses. The aerobic plate counts, as a predictor of freshness of fresh-cut papaya, significantly correlated with storage time. The SVMR model had a higher prediction accuracy than the PLSR model. Combining flavor quality with multivariate statistical analysis can be effectively used for evaluating the freshness of fresh-cut papaya.

    背景:本研究调查了自体骨髓细胞(BMC)治疗严重肢体缺血(CLI)患者的结果和可能的预测因素。重点探讨了与BMC治疗疗效相关的临床背景和先前的他汀类药物和肾素-血管紧张素系统(RAS)作用剂药物治疗。
    方法:在本研究中,我们回顾了33例(平均年龄64.9±10岁;31例男性)在血运重建失败或不可能后出现晚期CLI的患者。通过局部肌内应用用40mL自体BMC治疗。保肢和伤口愈合的患者(N=22)被认为是BMC治疗的应答者,并且将具有肢体抢救和完全缺血性伤口愈合的患者(N=13)定义为超应答者。采用Logistic回归模型筛选并确定预后因素,和接收器工作特性(ROC)曲线,线性回归,并绘制生存曲线以确定预测准确性,候选预测因子之间的相关性,以及严重截肢的风险。
    结果:基于单变量回归分析,基线C反应蛋白(CRP)和经皮氧分压(TcPO2)值被确定为反应者的预后因素,而CRP值,踝肱指数(ABI),和骨髓来源的单核细胞(BM-MNCs)浓度被确定为超应答者的预后因素。ROC曲线下面积为0.768,表明移植前CRP>8.1mg/L具有良好的鉴别性,可作为阴性临床反应的预测因素。线性回归分析显示,基线CRP水平与移植骨髓中BM-MNCs浓度之间存在显着依赖性。在BMCs治疗前服用阿托伐他汀的患者(N=22)在BMCs移植后TcPO2显著改善,疼痛评分降低,与非阿托伐他汀组相比。他汀类药物治疗与严重截肢风险降低相关。然而,差异无统计学意义。与未使用他汀类药物治疗的患者相比,他汀类药物的使用还与移植骨髓中BM-MNC的浓度显着升高有关。使用RAS作用剂治疗的患者(N=20)在BMC移植后疼痛评分显着降低,与非RAS作用药物组相比。类似的结果,在BMC治疗前,阿托伐他汀和RAS作用药物治疗的患者(N=17)疼痛评分降低,TcPO2改善.Spearman相关结果显示CLI回归之间存在显著正相关,响应者,以及单独使用RAS作用剂或阿托伐他汀进行BMC移植前的先前治疗。
    结论:CRP和TcPO2是反应者的预后因素,而CRP值,ABI,和BM-MNCs浓度被确定为超应答者的预测因素。在CLI患者中,阿托伐他汀治疗与骨髓浓缩物中BM-MNC的浓度显著增加以及BMC治疗后较高的TcPO2和较低的疼痛评分相关。同样,在BMCs治疗前,接受阿托伐他汀和RAS作用药物治疗的患者疼痛评分降低,TcPO2改善.在单独使用RAS作用剂或阿托伐他汀进行BMC移植之前,应答者与先前治疗之间的正相关是显着的。
    BACKGROUND: The present study investigated the outcomes and possible predictive factors of autologous bone marrow cells (BMCs) therapy in patients with \"no-option\" critical limb ischaemia (CLI). It was focused on exploring the clinical background and prior statin and renin-angiotensin system (RAS)-acting agents pharmacotherapy related to the therapeutic efficacy of BMCs treatment.
    METHODS: In the present study, we reviewed thirty-three patients (mean age 64.9 ± 10 years; 31 males) with advanced CLI after failed or impossible revascularisation, who were treated with 40 mL of autologous BMCs by local intramuscular application. Patients with limb salvage and wound healing (N = 22) were considered as responders to BMCs therapy, and patients with limb salvage and complete ischemic wound healing (N = 13) were defined as super-responders. Logistic regression models were used to screen and identify the prognostic factors, and a receiver operating characteristics (ROC) curve, a linear regression, and a survival curve were drawn to determine the predictive accuracy, the correlation between the candidate predictors, and the risk of major amputation.
    RESULTS: Based on the univariate regression analysis, baseline C-reactive protein (CRP) and transcutaneous oxygen pressure (TcPO2) values were identified as prognostic factors of the responders, while CRP value, ankle-brachial index (ABI), and bone marrow-derived mononuclear cells (BM-MNCs) concentration were identified as prognostic factors of the super-responders. An area under the ROC curve of 0.768 indicated good discrimination for CRP > 8.1 mg/L before transplantation as a predictive factor for negative clinical response. Linear regression analysis revealed a significant dependence between the levels of baseline CRP and the concentration of BM-MNCs in transplanted bone marrow. Patients taking atorvastatin before BMCs treatment (N = 22) had significantly improved TcPO2 and reduced pain scale after BMCs transplant, compared to the non-atorvastatin group. Statin treatment was associated with reduced risk for major amputation. However, the difference was not statistically significant. Statin use was also associated with a significantly higher concentration of BM-MNCs in the transplanted bone marrow compared to patients without statin treatment. Patients treated with RAS-acting agents (N = 20) had significantly reduced pain scale after BMCs transplant, compared to the non-RAS-acting agents group. Similar results, reduced pain scale and improved TcPO2, were achieved in patients treated with atorvastatin and RAS-acting agents (N = 17) before BMCs treatment. Results of the Spearman correlation showed a significant positive correlation between CLI regression, responders, and previous therapy before BMCs transplant with RAS-acting agents alone or with atorvastatin.
    CONCLUSIONS: CRP and TcPO2 were prognostic factors of the responders, while CRP value, ABI, and BM-MNCs concentration were identified as predictive factors of the super-responders. Atorvastatin treatment was associated with a significantly increased concentration of BM-MNCs in bone marrow concentrate and higher TcPO2 and lower pain scale after BMCs treatment in CLI patients. Similarly, reduced pain scales and improved TcPO2 were achieved in patients treated with atorvastatin and RAS-acting agents before BMCs treatment. Positive correlations between responders and previous treatment before BMCs transplant with RAS-acting agents alone or with atorvastatin were significant.

    这项研究旨在确定整个人口的可及性,尤其是贫民窟人口到现有的医疗设施(HCF)以及地理可达性低的贫民窟社区,最后,为生活在研究区域现有医疗保健设施(HCF)覆盖范围之外的地区的人们提供分析模型。已根据道路网络收集和使用了空间数据,高程,HCF的位置,市政边界,贫民窟点,和各种来源的卫星图像。此外,社会经济变量等非空间数据是从特定时期的问卷调查中收集的。空间分析工具就像近一样,网络分析,并使用ArcGIS平台中的预测分析来检查地理可达性。空间分析的结果表明,研究区域内公共医疗机构中心的分布并未均匀分布。研究区域中84%的区域具有声音空间可达性,旅行时间覆盖范围约为12分钟。然而,在现有贫民窟社区的可及性较低的情况下,16%的地区的旅行时间为12至30分钟。因此,低空间可达性区域需要研究区域的新医疗设施。采用层次分析法(AHP)来寻找建立新医疗机构中心的最佳和有效的位置适用性。AHP分析发现医疗设施的场地适宜性,发现五个主要类别是最合适的(2%),适合(5%),中等(35%),差(54%),在研究区域非常差(4%)。此外,本研究的现实框架有助于衡量任何地理区域的地理可达性和适用性。
    This research aims to identify the accessibility of the entire population, especially the slum population to existing healthcare facilities (HCF) as well as the slum neighborhoods having low geographic accessibility, and finally, to provide an analytical model for the people living in areas that are outside the coverage range of existing healthcare facilities (HCF) across the study area. Spatial data has been collected and used based on the road network, elevation, location of HCF, municipal boundary, slum point, and satellite images from various sources. Also, non-spatial data such as socioeconomic variables are collected from questionnaires survey within a particular period. The spatial analysis tool like as near, network analysis, and predictive analysis in the ArcGIS platform was used to examine geographic accessibility. The results of the spatial analysis show that the distribution of public healthcare facility centers in the study area has not been uniformly distributed. Across 84% of areas in the study area have sound spatial accessibility with traveling time coverage is about 12 min. However, 16% of areas have a traveling time of 12 to 30 min under low accessibility with existing slum neighborhoods. Therefore, the low spatial accessibility areas are demanding new healthcare facilities in the study area. The Analytical Hierarchy Process (AHP) is employed to find the most optimal and efficient locational suitability for building new healthcare facility centers. The finding of AHP analysis for site suitability of healthcare facilities revealed five major classes as most suitable (2%), suitable (5%), moderate (35%), poor (54%), and very poor (4%) in the study area. Moreover, the realistic framework of this study helps to measure geographic accessibility and suitability in any geographical area.

    作为中国实现“双碳”战略的重要路径之一,氢燃料电池汽车的发展目前正在全国各地推广,包括乘用车、客车、重型卡车等。量化不同车型和地区的氢燃料电池汽车的碳减排潜力已成为研究热点。本研究采用综合考虑未来汽车燃油经济性、发电碳排放因子、产氢碳排放因子、区域规模差异和制氢方式差异的生命周期评价方法,对燃料电池汽车(FCV)、传统燃料汽车(ICEV)和纯电动汽车(BEV)等不同类型汽车的生命周期碳排放进行了定量评价。对比分析了不同时间、不同地区氢燃料电池汽车的碳减排潜力,并对百公里氢消耗量进行了不确定性分析。结果表明,到2025年,氢燃料电池客车的生命周期碳排放量将比传统燃料客车下降36.0%,但氢燃料电池重型卡车的碳排放量下降不显著。到2035年,随着我国氢能能源结构的不断完善,氢燃料电池重型车的全生命周期碳排放量预计将比传统燃料重型车下降36.5%。与乘用车和客车相比,重型卡车的脱碳潜力最重要。以2035年京津冀示范集团为例,随着百公里氢气消耗量下降20%,FCV乘用车、客车和重型卡车的碳减排潜力将分别提高7.29%、9.93%和19.57%。因此,建议短期内优先推广氢燃料电池客车,长期优先推广重型卡车,并以乘用车为补充。在不同地区、不同阶段推广氢燃料电池汽车,有助于推进我国汽车产业的低碳发展。
    As one of the important paths for China to achieve the \"dual carbon\" strategy, developing hydrogen fuel cell vehicles is currently being promoted in various regions across the country, including passenger cars, coaches, and heavy-duty trucks. Quantifying the carbon reduction potential of hydrogen fuel cell vehicles for different vehicle types and regions has become a hot research topic. Using a life cycle assessment method that considers future vehicle fuel economy, power generation carbon emission factors, hydrogen production carbon emission factors, and regional differences in the scale and hydrogen production methods, this study quantitatively evaluated the life cycle carbon emissions of different types of vehicles, including fuel cell vehicles (FCV), traditional fuel vehicles (ICEV), and battery electric vehicles (BEV). We compared and analyzed the carbon reduction potential of hydrogen fuel cell vehicles at different times and in different regions and conducted an uncertainty analysis on hydrogen consumption per hundred kilometers. The results showed that by 2025, the life cycle carbon emissions of hydrogen fuel cell coaches would decrease by 36.0% compared to that of traditional fuel coaches, but the reduction in carbon emissions for hydrogen fuel cell heavy-duty trucks was not significant. By 2035, as the hydrogen energy source structure in China continues to improve, the life cycle carbon emissions of hydrogen fuel cell heavy-duty trucks were predicted to decrease by 36.5% compared to that of traditional fuel heavy-duty trucks. The decarbonization potential was most significant for heavy-duty trucks compared to that of passenger cars and coaches. Taking the Beijing-Tianjin-Hebei demonstration group as an example in 2035, as the hydrogen consumption per hundred kilometers decreases by 20%, the carbon reduction potential of FCV passenger cars, coaches, and heavy-duty trucks would increase by 7.29%, 9.93%, and 19.57%, respectively. Therefore, it is recommended to prioritize the promotion of hydrogen fuel cell coaches in the short term, heavy-duty trucks in the long term, and passenger cars as a supplement. Promoting hydrogen fuel cell vehicles in different regions and stages will help advance the low-carbon development of the automotive industry in China.

    Objective To analyze the trends of disease burden of cervical cancer,uterine cancer,and ovarian cancer among Chinese women from 1990 to 2019,and to provide a basis for formulating precise prevention and control measures in China. Methods The global disease burden data in 2019 were used to describe the changes in indicators such as incidence,mortality,years of life lost due to premature mortality(YLL),years lived with disability(YLD),and disability-adjusted life year(DALY) of cervical,uterine,and ovarian cancers in China from 1990 to 2019.Furthermore,the Bayesian age-period-cohort model was adopted to predict the incidence and mortality of the cancers from 2020 to 2030. Results From 1990 to 2019,the incidence rates and mortality of cervical,uterine,and ovarian cancers in Chinese women showed an upward trend,and the age-standardized incidence rate of ovarian cancer increased the most(0.78%).In 2019,the incidence of cervical cancer and uterine cancer concentrated in the women of 55-59 years old,and ovarian cancer mainly occurred in the women of 70-74 years old.The DALY,YLL,and YLD of cervical,uterine,and ovarian cancers all presented varying degrees of growth at all ages.The Bayesian age-period-cohort model predicted that from 2020 to 2030,the incidence and mortality of cervical cancer in China showed a decreasing trend,while those of uterine cancer and ovarian cancer showed an increasing trend.There was no significant change in the age with high incidence of the three cancers. Conclusions From 1990 to 2019,the overall disease burden of cervical,uterine,and ovarian cancers in China increased,while the disease burden of cervical cancer decreased after 2020.It is recommended that the efforts should be doubled for the prevention and control of cervical,uterine,and ovarian cancers.
    目的 分析1990至2019年中国女性宫颈癌、子宫癌和卵巢癌的疾病负担变化趋势,为国家制订精准的防控策略提供依据。方法 基于2019年全球疾病负担数据,描述1990至2019年中国宫颈癌、子宫癌和卵巢癌的发病、死亡、早死亡损失寿命年(YLL)、伤残损失寿命年(YLD)、伤残调整生命年(DALY)等指标的变化情况,并使用贝叶斯年龄-时期-队列模型对2020至2030年发病及死亡情况进行预测。结果 1990至2019年中国女性宫颈癌、子宫癌和卵巢癌的发病率和死亡率均呈上升趋势,卵巢癌年龄标准化发病率增幅最高(0.78%)。2019年宫颈癌、子宫癌的高发年龄均为55~59岁,卵巢癌为70~74岁。宫颈癌、子宫癌和卵巢癌各年龄段的DALY、YLL、YLD均有不同程度的增长。贝叶斯年龄-时期-队列模型预测显示,2020至2030年中国宫颈癌的发病率和死亡率呈下降趋势,而子宫癌和卵巢癌的发病率和死亡率呈上升趋势,但3种肿瘤的高发年龄段没有明显变化。结论 1990至2019年中国宫颈癌、子宫癌和卵巢癌的疾病负担整体上升,2020年以后宫颈癌的疾病负担下降,建议进一步加强宫颈癌、子宫癌和卵巢癌的防控工作。.

    在大流行期间,死亡人数有所增加,这不能只用COVID-19来解释。实际死亡人数远远超过记录的与SARS-CoV-2感染直接相关的死亡数据。来自早期和短期大流行研究的数据表明,心血管死亡率发生了巨大变化。扎根于大流行后时代,大流行期间心血管死亡率的宏观大数据需要进一步审查和研究,这对心血管疾病的预防和控制至关重要。
    我们根据ICD-10代码从疾病控制和预防中心流行病学研究远程在线数据(CDCWONDER)平台的国家重要统计系统中检索并收集了与心血管疾病死亡率相关的数据。我们应用回归分析来表征2010年至2023年的总体心血管疾病死亡率趋势,并根据2010年至2019年的死亡率数据建立时间序列模型来预测2020年至2023年的死亡率,以通过评估观察到的与预测死亡率。我们还按性别进行了亚组分析,年龄和种族/民族,以获得更具体的社会人口统计信息。
    心血管疾病的全因年龄标准化死亡率(ASMR)在2019年至2021年之间急剧增加[年变化百分比(APC)11.27%,p<0.01],然后在接下来的2021-2023年下降(APC:-7.0%,p<0.01)。亚组分析发现,ASMR变化在阿拉斯加印第安人/美洲原住民中最为明显(APC:2019-2021年为16.5%,2021-2023年为-12.5%,均p<0.01)。西班牙裔(APC:2019-2021年为12.1%,2021-2023年为-12.2%,均p<0.05)和非西班牙裔黑人(APC:2019-2021年为11.8%,2021-2023年为-10.3%,均p<0.01)。同样,25-44岁年龄组(APC:2019-2021年为19.8%,2021-2023年为-15.4%,均p<0.01)和男性(APC:2019-2021年为11.5%,2021-2023年为-7.6%,均p<0.01)的ASMR变化尤为显著.截至2023年底,老年人与COVID相关的超额死亡比例仍然很高(22.4%),男性(42.8%)和阿拉斯加印第安人/美洲原住民(39.7%)。此外,我们在2023年没有发现年轻人(25~44人)和中年队列(45~64人)的超额死亡,而老年人的超额死亡仍然存在.
    在COVID-19大流行的最初两年,心血管疾病的所有原因ASMR明显增加,然后在2021-2023年下降。同伙(年轻人,死亡率上升最快的男性和少数民族)反而以最快的速度下降。以前促进心血管健康的举措是有效的,但考虑到心血管疾病死亡中存在的社会人口统计学差异,应优先进一步研究老年人的心血管保健和种族差异.
    UNASSIGNED: An increase in deaths has been perceived during the pandemic, which cannot be explained only by COVID-19. The actual number of deaths far exceeds the recorded data on deaths directly related to SARS-CoV-2 infection. Data from early and short-lived pandemic studies show a dramatic shift in cardiovascular mortality. Grounded in the post-pandemic era, macroscopic big data on cardiovascular mortality during the pandemic need to be further reviewed and studied, which is crucial for cardiovascular disease prevention and control.
    UNASSIGNED: We retrieved and collected data associated with cardiovascular disease mortality from the National Vital Statistic System from the Center for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER) platform based on the ICD-10 codes. We applied regression analysis to characterize overall cardiovascular disease mortality trends from 2010 to 2023 and built a time series model to predict mortality for 2020-2023 based on mortality data from 2010 to 2019 in order to affirm the existence of the excess deaths by evaluating observed vs. predicted mortality. We also conducted subgroup analyses by sex, age and race/ethnicity for the purpose of obtaining more specific sociodemographic information.
    UNASSIGNED: All-cause age-standardised mortality rates (ASMRs) for CVD dramatically increased between 2019 and 2021[annual percentage change (APC) 11.27%, p < 0.01], and then decreased in the following 2021-2023(APC: -7.0%, p < 0.01). Subgroup analyses found that the ASMR change was most pronounced in Alaska Indians/Native American people (APC: 16.5% in 2019-2021, -12.5% in 2021-2023, both p < 0.01), Hispanics (APC: 12.1% in 2019-2021, -12.2% in 2021-2023, both p < 0.05) and non-Hispanic Black people (APC:11.8% in 2019-2021, -10.3% in 2021-2023, both p < 0.01)whether during the increasing or declining phase. Similarly, the ASMR change was particularly dramatic for the 25-44 age group (APC:19.8% in 2019-2021, -15.4% in 2021-2023, both p < 0.01) and males (APC: 11.5% in 2019-2021, -7.6% in 2021-2023, both p < 0.01). By the end of 2023, the proportion of COVID-related excess death remained high among the elderly (22.4%), males (42.8%) and Alaska Indians/Native American people(39.7%). In addition, we did not find the presence of excess deaths in the young (25-44) and middle-aged cohort (45-64) in 2023, while excess deaths remained persistent in the elderly.
    UNASSIGNED: All-cause ASMRs for CVD increased notably during the initial two years of the COVID-19 pandemic and then witnessed a decline in 2021-2023. The cohorts (the young, males and minorities) with the steepest rise in mortality decreased at the fastest rate instead. Previous initiatives to promote cardiovascular health were effective, but further research on cardiovascular healthcare for the elderly and racial disparities should be attached to priority considering the presence of sociodemographic differences in CVD death.
