    目的:了解1990年至2019年中国和全球水果摄入不足导致的食管癌(EC)疾病负担,按年龄和性别进行分层。
    方法:合并全球疾病负担研究(GBD2019)以计算死亡人数,标准化死亡率,1990年至2019年,中国和全球按年龄和性别划分的水果摄入量低,导致残疾调整生命年(DALY)和EC的DALY率。应用种群归因分数(PAF)估算了低水果摄入量引起的EC比例。Joinpoint用于估算年均变化百分比(AAPC),以反映中国和全球因水果摄入量不足而导致的EC负担的时间变化趋势。
    结果:在2019年的中国人口中,男性EC的归因DALY为356,000人年,而女性为80,600人年。中国不同年龄组归因标准化死亡率和DALY率随年龄增长而增加,在70岁及以上的人群中达到顶峰。从1990年到2019年在中国,死亡人数,标准化死亡率,由于水果摄入不足而导致的EC的DALY和标准化DALY率呈下降趋势(AAPC:-1.62%,-4.54%,-2.10%和-4.88%,分别),具有统计学意义(P<0.001)。
    结论:中国水果摄入不足导致的欧共体总体负担呈下降趋势。然而,由于人口老龄化,中国的疾病负担仍然高于全球平均水平。因此,预防和健康教育工作应集中在水果摄入量低的人群上。
    OBJECTIVE: To understand the disease burden of esophageal cancer (EC) attributable to inadequate fruit intake in China and global from 1990 to 2019 stratified by age and sex.
    METHODS: Global Burden of Disease Study (GBD 2019) were pooled to calculate the number of deaths, standardized mortality rate, disability-adjusted life years (DALY) and DALY rate of EC attributed to low fruit intake in China and globally by age and sex from 1990 to 2019. The population attributable fractions (PAF) were applied to estimate the proportion of EC caused by low fruit intake. Joinpoint was used to estimate average annual percentage of change (AAPC) to reflect the time change trend of the EC burden attributable to inadequate fruit intake in China and globally.
    RESULTS: In the Chinese population in 2019, the attributable DALY of EC in males was 356,000 person-years, while it was 80,600 person-years in females. The attributable standardized mortality and DALY rates for different age groups in China increased with age, peaking in the group aged 70 years and above. From 1990 to 2019 in China, the number of deaths, standardized mortality rates, DALY and standardized DALY rates of EC attributable to inadequate fruit intake showed a decreasing trend (AAPCs: -1.62%, -4.54%, -2.10% and -4.88%, respectively), with statistical significance (P<0.001).
    CONCLUSIONS: The overall burden of EC attributed to inadequate fruit intake in China has demonstrated a downward trend. However, due to the aging population, the disease burden in China remains higher than the global average. Hence, prevention and health education efforts should focus on the population with low fruit intake.

    准确预测Kirsten大鼠肉瘤(KRAS)突变状态对于晚期结直肠癌患者的个性化治疗至关重要。然而,尽管深度学习模型在某些方面表现优异,他们往往忽视了多项任务之间的协同促进以及全球和本地信息的考虑,这可能会大大降低预测精度。为了解决这些问题,本文提出了一种称为多任务全局-局部协作混合网络(CHNet)的创新方法,旨在更准确地预测患者的KRAS突变状态。CHNet由两个分支组成,可以从分割和分类任务中提取全局和局部特征,分别,并交换补充信息以协作执行这些任务。在两个分支中,我们设计了一个通道混合变压器(CHT)和空间混合变压器(SHT)。这些变压器集成了变压器和CNN的优点,采用级联混合注意力和卷积从两个任务中捕获全局和局部信息。此外,我们创建了一个自适应协同注意(ACA)模块,以促进通过指导分割和分类特征的协同融合。此外,我们引入了一种新颖的类激活图(CAM)损失,以鼓励CHNet学习两个任务之间的互补信息。我们在T2加权MRI数据集上评估CHNet,KRAS突变状态预测准确率达到88.93%,其性能优于代表性的KRAS突变状态预测方法。结果表明,我们的CHNet可以通过多任务协作促进和考虑全局-局部信息的方式更准确地预测患者的KRAS突变状态。这可以帮助医生为患者制定更个性化的治疗策略。
    Accurate prediction of Kirsten rat sarcoma (KRAS) mutation status is crucial for personalized treatment of advanced colorectal cancer patients. However, despite the excellent performance of deep learning models in certain aspects, they often overlook the synergistic promotion among multiple tasks and the consideration of both global and local information, which can significantly reduce prediction accuracy. To address these issues, this paper proposes an innovative method called the Multi-task Global-Local Collaborative Hybrid Network (CHNet) aimed at more accurately predicting patients\' KRAS mutation status. CHNet consists of two branches that can extract global and local features from segmentation and classification tasks, respectively, and exchange complementary information to collaborate in executing these tasks. Within the two branches, we have designed a Channel-wise Hybrid Transformer (CHT) and a Spatial-wise Hybrid Transformer (SHT). These transformers integrate the advantages of both Transformer and CNN, employing cascaded hybrid attention and convolution to capture global and local information from the two tasks. Additionally, we have created an Adaptive Collaborative Attention (ACA) module to facilitate the collaborative fusion of segmentation and classification features through guidance. Furthermore, we introduce a novel Class Activation Map (CAM) loss to encourage CHNet to learn complementary information between the two tasks. We evaluate CHNet on the T2-weighted MRI dataset, and achieve an accuracy of 88.93% in KRAS mutation status prediction, which outperforms the performance of representative KRAS mutation status prediction methods. The results suggest that our CHNet can more accurately predict KRAS mutation status in patients via a multi-task collaborative facilitation and considering global-local information way, which can assist doctors in formulating more personalized treatment strategies for patients.

    后院的鸡通常有开放的住房和觅食,促进与环境中存在的感染形式的寄生虫接触,并增加寄生虫感染的风险。球虫病和a虫病是清除鸡中的两种内部寄生虫,会给农民造成生产损失。在低收入和中等收入国家(LMICs)中,这两种疾病的患病率数据很少,但对于评估后院鸡的疾病负担是必要的。本研究使用回归归因方法估算了所有LMICs国家和地区水平的球虫病和a虫病的临床患病率。使用这些寄生虫的已知患病率数据并主要使用气候因素作为预测因子来开发回归模型。为每种疾病开发了二项随机效应模型,以估算患病率。球虫病的总体估计患病率为0.39(95%CI:0.37-0.42),在热带国家的平均患病率较高。总体估计的蛔虫病患病率为0.23(95%CI:0.22-0.25),在热带国家平均患病率较高,温带和大陆性气候。这项研究的结果可以帮助确定不同国家和地区的球虫病和蛔虫病感染的负担,它可以为疾病控制计划提供信息,并鼓励国际联盟促进获得预防措施,改善动物健康,减少生产损失。
    Backyard chickens usually have open housing and scavenge for food, facilitating contact with infective forms of parasites present in the environment and increasing the risk of parasitic infections. Coccidiosis and ascaridiosis are two internal parasites in scavenging chickens that cause production losses to farmers. Prevalence data of these two diseases are scarce in low-income and middle-income countries (LMICs) but necessary to assess the burden of disease in backyard chickens. This study estimates the clinical prevalence of coccidiosis and ascaridiosis at the country and regional levels in all LMICs using regression imputation methods. Regression models were developed with data of known prevalence of these parasites and using primarily climatic factors as predictors. A binomial random effects model was developed for each disease to impute prevalence. The overall estimated prevalence of coccidiosis was 0.39 (95 % CI: 0.37-0.42), with a higher mean prevalence in tropical countries. The overall estimated prevalence of ascaridiosis was 0.23 (95 % CI: 0.22-0.25) with a higher mean prevalence in countries with tropical, temperate and continental climates. The findings of this study can aid to identify the burdens of coccidiosis and ascaridiosis infections across countries and regions, which can inform disease control plans and, and encourage international alliances to facilitate access to preventive measures, improving animal health and reducing production losses.

    目的:肝癌是全球和中国的主要健康问题。这项分析调查了中国和全球肝癌的病因和危险因素的死亡和残疾调整生命年(DALYs)。
    方法:收集了全球和中国特有的肝癌死亡数据,DALYs,和年龄标准化率(ASR)来自2019年全球疾病负担研究数据库。肝癌的病因分为五组,危险因素分为三个级别。在不同的地理区域计算每个比例的肝癌负担。使用连接点回归模型评估1990-2019年的趋势。
    结果:2019年全球肝癌死亡人数为484,577人,ASR为每100,000人中5.9人。2019年,中国肝癌死亡ASR升高,男性ASR是全球的1.7倍。DALYs的全球ASR在75-79岁达到峰值,但在中国达到峰值较早。乙型肝炎病毒是全球(39.5%)和中国(62.5%)的突出病因,其次是丙型肝炎病毒和饮酒。在社会人口指数高的国家,非酒精性脂肪性肝炎作为病因学因素的贡献越来越大.由于各种病因导致的肝癌负担在全球范围内都有所下降。然而,代谢危险因素,特别是肥胖,对肝癌负担的贡献越来越大,尤其是男性。
    结论:尽管中国和世界范围内肝癌负担总体呈下降趋势,代谢风险因素的贡献在上升,强调执行有针对性的预防和控制战略以解决区域和性别差距的重要性。
    OBJECTIVE: Liver cancer is a major health concern globally and in China. This analysis investigated deaths and disability-adjusted life years (DALYs) with respect to etiologies and risk factors for liver cancer in China and worldwide.
    METHODS: Global and China-specific data were collected on liver cancer deaths, DALYs, and age-standardized rates (ASRs) from the Global Burden of Disease Study 2019 database. Liver cancer etiologies were classified into five groups and risk factors were categorized into three levels. Each proportion of liver cancer burden was calculated in different geographic regions. The joinpoint regression model were used to assess the trends from 1990-2019.
    RESULTS: Liver cancer accounted for 484,577 deaths worldwide in 2019 with an ASR of 5.9 per 100,000 population. China had an elevated liver cancer death ASR in 2019 and males had an ASR 1.7 times the global rate. The global ASR for DALYs peaked at 75-79 years of age but peaked earlier in China. Hepatitis B virus was the prominent etiology globally (39.5%) and in China (62.5%), followed by hepatitis C virus and alcohol consumption. In high sociodemographic index countries, non-alcoholic steatohepatitis has gained an increasing contribution as an etiologic factor. The liver cancer burden due to various etiologies has decreased globally in both genders. However, metabolic risk factors, particularly obesity, have had a growing contribution to the liver cancer burden, especially among males.
    CONCLUSIONS: Despite an overall decreasing trend in the liver cancer burden in China and worldwide, there has been a rising contribution from metabolic risk factors, highlighting the importance of implementing targeted prevention and control strategies that address regional and gender disparities.

    食物过敏患病率的增加被认为是继哮喘和过敏性鼻炎的第一波增加之后的第二波过敏流行。众所周知,在许多国家或地区,过敏性疾病的流行将伴随着经济发展和城市化。在发达国家,三分之一的儿童患有至少一种过敏性疾病,这些疾病包括食物过敏,湿疹,过敏性鼻炎和哮喘。食物过敏通常是影响婴幼儿的第一过敏表现。确切的病因尚不清楚。临床表现包括单纯性皮疹或口腔周围瘙痒,血管性水肿和潜在致命的过敏反应的更严重的表现。在所有儿童过敏反应病例中,食物是最常见的原因。在发达国家,导致食物过敏的常见过敏原包括鸡蛋,牛奶,鱼,小麦,花生和坚果。然而,发展中国家的食物过敏原模式存在明显差异。根据哮喘的流行病学,食物过敏在农村地区也不太常见。清楚了解解释城乡人口食物过敏差异的原因将为制定有效的食物过敏一级预防方法铺平道路。
    The increase in the prevalence of food allergy has been considered as the second wave in the allergy epidemic following the first wave of increase in asthma and allergic rhinitis. It is well known that the prevalence of allergic conditions would follow economic development and urbanization in many countries or regions. In developed countries, one in three children suffered from at least one allergic disorder and these conditions include food allergy, eczema, allergic rhinitis and asthma. Food allergy is very often the first allergic manifestation affecting infants and young children. The exact etiologies are not known. The clinical manifestations ranged from a simple rash or an itch around the mouth, to the more severe manifestations of angioedema and potentially fatal anaphylaxis. Among all cases of childhood anaphylaxis, food is the most common cause. The common allergens resulting in food allergies in developed countries include egg, milk, fish, wheat, peanuts and tree nuts. However, there are marked variations in the patterns of food allergens in developing countries. In line with the epidemiology of asthma, food allergy is also much less common in rural areas. Clear understanding of reasons explaining the disparity of food allergies between urban and rural population would pave the way to the development of effective primary prevention for food allergy.

    绿色金融在当前时代推动清洁能源和环境可持续性方面的有效性受到关注。因此,本研究提出了一个实证框架,强调绿色债券(GB)对清洁能源投资(CEI)的影响,2014年至2022年期间,29个绿色债券发行国的清洁能源投资效率(CEE)和环境可持续性。使用系统和差异GMM方法,本研究发现(I)绿色债券发行推动清洁能源投资。(二)绿色债券足以提高选定国家的环境质量。这些结果补充了绿色债券的推广,通过减少对化石燃料的依赖,增加了对可再生能源项目的资金转移。(iii)使用Driscoll&Kraay,完全修改-OLS,并改变因变量,这项研究进一步支持了绿色债券有效促进所选国家的中东欧和环境可持续性的想法。(四)同样,这项研究进行了收入异质性,表明绿色债券改善了高收入和中等收入国家的CEI和环境质量。(五)最后,结果表明,资源消耗通过降低CEI来增加CO2排放。技术创新增加CEI,虽然它们不能直接减少二氧化碳排放,暗示需要采取全面的方法。因此,关于绿色债券框架的包容性政策,强有力的激励措施,应实施严格的环境标准,以吸引对清洁能源开发的投资,并确保选定国家的环境可持续性。
    The effectiveness of green finance in driving clean energy and environmental sustainability in the current era is receiving attention. Therefore, this study proposes an empirical framework highlighting the effects of green bonds (GB) on clean energy investment (CEI), clean energy investment efficiency (CEE) and environmental sustainability of 29 green bond issuing countries between 2014 and 2022. Using system and difference GMM approaches, this study finds that (i) green bond issuance drives clean energy investment. (ii) Green bonds sufficiently enhance the selected countries\' environmental quality. These results supplement the promotion of green bonds in increasing the transfer of funds towards renewable energy projects by reducing reliance on fossil fuels. (iii) Using Driscoll & Kraay, Fully Modified-OLS, and changing the dependent variable, this study further supported the idea that green bonds effectively promote the CEE and environmental sustainability of the chosen countries. (iv) Similarly, this study conducted income heterogeneity, showing that green bonds improve high- and middle-income countries\' CEI and environmental quality. (v) Finally, the results indicate that resource consumption escalates CO2 emissions by declining the CEI. Technological innovations increase CEI, whereas they do not mitigate CO2 emissions directly, hinting at the requirement for a comprehensive approach. Therefore, inclusive policies on green bond frameworks, robust incentives, and rigorous environmental criteria should be implemented to attract investment in clean energy development and ensure the environmental sustainability of the selected countries.

    结果:只有中国,丹麦,英格兰,希腊,北爱尔兰,苏格兰,西班牙,美国在其国家计划中提到了ECDR。此外,17个国家通过痴呆症组织正式提供EDR支持。支持工作包括研究经费,传播和网络,职业发展,和研究建议。
    结论:很少有国家在痴呆症计划中或通过痴呆症组织正式认可ECDR。为了促进ECD的平等前景,敦促自上而下的方法加强和协调他们的努力。
    结论:很少有G20国家(8/46)为早期职业研究人员制定了国家痴呆症计划。有针对性的支持来自政府和非政府痴呆症组织。支持包括资金,培训,建议,研究传播,和网络。不一致的定义和资格标准是获得支持的障碍。全球协调和自上而下的政策将帮助早期职业痴呆症研究人员。
    Despite representing an essential workforce, it is unclear how global policy efforts target early-career dementia researchers (ECDRs). Thus, this study aimed to provide an overview of policies through which ECDRs are considered and supported by dementia plans and organizations.
    G20 member states were evaluated for their national dementia plan alongside policies of leading dementia organizations. Data targeting support for ECDRs were extracted and subject to content analysis using inductive coding. Findings were categorized and narratively synthesized.
    Only China, Denmark, England, Greece, Northern Ireland, Scotland, Spain, and the United States mentioned ECDRs in their national plan. Additionally, 17 countries formalized ECDR support via dementia organizations. Support efforts included research funding, dissemination and networking, career development, and research advice.
    Few nations formally recognized ECDRs in dementia plans or through dementia organizations. To facilitate equal prospects for ECDRs, top-down approaches are urged to enhance and align their efforts.
    Few G20 countries (8/46) had national dementia plans for early-career researchers. Targeted support comes from government and nongovernmental dementia organizations. Support includes funding, training, advice, research dissemination, and networking. Inconsistent definitions and eligibility criteria are barriers to accessing support. Global coordination and top-down policy will aid early-career dementia researchers.

    世界各地都报道了呼吸道合胞病毒(RSV)的各种季节性模式。我们根据2020年1月1日之前收集的数据,对PubMed报告RSV季节性的文章进行了系统评价。RSV季节性模式按地理位置进行了检查,日历月,分析方法,和气象因素,包括温度和绝对湿度。进行了相关和回归分析,以探讨RSV季节性与研究方法和研究地点特征之间的关系。在1973-2023年发表的209篇文章中,报道了77个国家317个地点的RSV季节。在温带地区的国家中,定期RSV季节也有类似的报道,在亚热带和热带国家具有高度可变的季节。RSV季节的持续时间较长与较高的日平均平均温度和日平均绝对湿度相关。RSV的全球季节性模式为优化针对RSV感染的干预措施提供了重要信息。
    Varied seasonal patterns of respiratory syncytial virus (RSV) have been reported worldwide. We conducted a systematic review on articles identified in PubMed reporting RSV seasonality based on data collected before 1 January 2020. RSV seasonal patterns were examined by geographic location, calendar month, analytic method, and meteorological factors including temperature and absolute humidity. Correlation and regression analyses were conducted to explore the relationship between RSV seasonality and study methods and characteristics of study locations. RSV seasons were reported in 209 articles published in 1973-2023 for 317 locations in 77 countries. Regular RSV seasons were similarly reported in countries in temperate regions, with highly variable seasons identified in subtropical and tropical countries. Longer durations of RSV seasons were associated with a higher daily average mean temperature and daily average mean absolute humidity. The global seasonal patterns of RSV provided important information for optimizing interventions against RSV infection.

    针对狭窄通道环境中的机器人路径规划问题,本文提出了一种新颖的全局路径规划方法:DSR(双源光连续反射探测)算法。这个算法,灵感来自光线的自然反射,采用连续反射的概念进行路径规划。它可以在包含狭窄通道的地图上有效地生成渐近最佳路径。DSR算法已在具有窄通道的不同地图上进行了评估,并与其他算法进行了比较。与双向快速探索随机树算法相比,DSR算法实现了路径长度(27.08%和34.35%)和时间消耗(98.47%和91.03%)的显着减少。数值仿真和实验分析证明了DSR算法的优良性能。
    Aiming to address the problem of robot path planning in environments containing narrow passages, this paper proposes a novel global path planning method: the DSR (Dual-source Light Continuous Reflection Exploration) algorithm. This algorithm, inspired by the natural reflection of light, employs the concept of continuous reflection for path planning. It can efficiently generate an asymptotically optimal path on the map containing narrow passages. The DSR algorithm has been evaluated on different maps with narrow passages and compared with other algorithms. In comparison with the bidirectional Rapidly-exploring Random Tree algorithm, the DSR algorithm achieves a significant reduction in both path length (by 27.08% and 34.35%) and time consumption (by 98.47% and 91.03%). Numerical simulations and experimental analysis have demonstrated the excellent performance of the DSR algorithm.

    我们的目标是评估全球,区域,和1990年至2019年子宫癌(UC)的国家负担。
    我们利用全球疾病负担数据库(GBD)2019年公共数据集,收集了1990-2019年期间204个国家和地区的UC数据。采用Joinpoint回归分析来确定全球趋势变化最显著的年份。为了预测2020年至2044年的UC轨迹,我们应用了Nordpred分析,根据数据中观察到的平均趋势进行外推。此外,实施了具有集成嵌套Laplace近似的贝叶斯年龄-周期-队列(BAPC)模型,以确认Nordpred分析预测的稳定性.
    全球,从1990年到2019年,UC的年龄标准化发病率(ASR)有所增加,年平均百分比变化(AAPC)为0.50%.死亡的ASR在同一时期内下降(AAPC:-0.8%)。在所有社会人口指数(SDI)地区,发病率的ASR都有所增加。特别是在高SDI地区(AAPC:1.12%),而死亡的ASR在除低SDI地区以外的所有地区都下降了。在过去的30年里,在55-59岁的个体中观察到最高的发病率(AAPC:0.76%).在204个国家和地区中,165个国家的ASR发病率增加,77个国家的ASR死亡率增加.我们的预测表明,从2020年到2044年,UC的发病率和死亡率都可能继续下降。
    UC对全球健康产生了重大负面影响,其影响来自一系列因素,包括地理位置,年龄和种族差异,和SDI。
    UNASSIGNED: We aim to evaluate the global, regional, and national burden of Uterine Cancer (UC) from 1990 to 2019.
    UNASSIGNED: We gathered UC data across 204 countries and regions for the period 1990-2019, utilizing the Global Burden of Disease Database (GBD) 2019 public dataset. Joinpoint regression analysis was employed to pinpoint the year of the most significant changes in global trends. To project the UC trajectory from 2020 to 2044, we applied the Nordpred analysis, extrapolating based on the average trend observed in the data. Furthermore, the Bayesian Age-Period-Cohort (BAPC) model with integrated nested Laplace approximations was implemented to confirm the stability of the Nordpred analysis predictions.
    UNASSIGNED: Globally, the age-standardized rate (ASR) of incidence for UC has increased from 1990 to 2019 with an Average Annual Percentage Change (AAPC) of 0.50%. The ASR for death has declined within the same period (AAPC: -0.8%). An increase in the ASR of incidence was observed across all Socio-demographic Index (SDI) regions, particularly in High SDI regions (AAPC: 1.12%), while the ASR for death decreased in all but the Low SDI regions. Over the past 30 years, the highest incidence rate was observed in individuals aged 55-59 (AAPC: 0.76%). Among 204 countries and regions, there was an increase in the ASR of incidence in 165 countries and an increase in the ASR of deaths in 77 countries. Our projections suggest that both the incidence and death rates for UC are likely to continue their decline from 2020 to 2044.
    UNASSIGNED: UC has significantly impacted global health negatively, with its influence stemming from a range of factors including geographical location, age-related and racial disparities, and SDI.
