    烘烤是带出咖啡豆的香气和风味的必要条件,使咖啡成为消耗最多的饮料之一。然而,这个过程还会产生一系列有毒化合物,包括丙烯酰胺和呋喃化合物(5-羟甲基糠醛,呋喃,2-甲基呋喃,3-甲基呋喃,2,3-二甲基呋喃,和2,5-二甲基呋喃)。此外,关于这些化合物在含有酒精和糖的新兴咖啡配方中的形成知之甚少。因此,本研究采用快速和慢速烘烤方法,研究了烘烤时间和程度对阿拉伯咖啡中丙烯酰胺和呋喃化合物含量的影响。快速和慢速焙烧方法分别为5.62min和9.65min,分别,并达到最高210°C以实现轻度烘烤。对于非常黑暗的烤肉,将咖啡豆烘烤10.5分钟,最高温度达到245°C。我们的发现表明,慢速烘焙咖啡中丙烯酰胺(375±2.52μgkg-1)和5-HMF(194±11.7mgkg-1)的含量比快速烘焙咖啡低35.0%和17.4%。此外,淡烘焙咖啡的丙烯酰胺和5-HMF浓度明显低于非常暗的烘焙咖啡,值分别为93.7±7.51μgkg-1和21.3±10.3mgkg-1。然而,呋喃和烷基呋喃的含量随着焙烧时间和程度的增加而增加。在这项研究中,我们还检查了这些污染物在新的咖啡配方中的浓度,包括酒精,sugar-,和蜂蜜咖啡豆。蜂蜜和糖的配方导致更高浓度的5-HMF,但对于丙烯酰胺没有观察到明显的趋势。另一方面,蜂蜜配方中呋喃和烷基呋喃的浓度较高。这些结果表明,优化焙烧时间和温度可能无法同时减少所有污染物。此外,注入糖和蜂蜜的咖啡豆必然含有较高的呋喃化合物,带来更高的健康风险。
    Roasting is necessary for bringing out the aroma and flavor of coffee beans, making coffee one of the most consumed beverages. However, this process also generates a series of toxic compounds, including acrylamide and furanic compounds (5-hydroxymethylfurfural, furan, 2-methylfuran, 3-methylfuran, 2,3-dimethylfuran, and 2,5-dimethylfuran). Furthermore, not much is known about the formation of these compounds in emerging coffee formulations containing alcohol and sugars. Therefore, this study investigated the effect of roasting time and degree on levels of acrylamide and furanic compounds in arabica coffee using fast and slow roasting methods. The fast and slow roasting methods took 5.62 min and 9.65 min, respectively, and reached a maximum of 210 °C to achieve a light roast. For the very dark roast, the coffee beans were roasted for 10.5 min and the maximum temperature reached 245 °C. Our findings showed that the levels of acrylamide (375 ± 2.52 μg kg-1) and 5-HMF (194 ± 11.7 mg kg-1) in the slow-roasted coffee were 35.0 % and 17.4 % lower than in fast-roasted coffee. Furthermore, light roast coffee had significantly lower concentrations of acrylamide and 5-HMF than very dark roast, with values of 93.7 ± 7.51 μg kg-1 and 21.3 ± 10.3 mg kg-1, respectively. However, the levels of furan and alkylfurans increased with increasing roasting time and degree. In this study, we also examined the concentrations of these pollutants in new coffee formulations consisting of alcohol-, sugar-, and honey-infused coffee beans. Formulations with honey and sugar resulted in higher concentrations of 5-HMF, but no clear trend was observed for acrylamide. On the other hand, formulations with honey had higher concentrations of furan and alkylfurans. These results indicate that optimizing roasting time and temperature might not achieve the simultaneous reduction of all the pollutants. Additionally, sugar- and honey-infused coffee beans are bound to have higher furanic compounds, posing a higher health risk.

    关于马铃薯病害的研究已经被广泛报道,但是缺乏对马铃薯疾病的系统评价。这里,采用文献计量学方法对马铃薯病害的研究进展进行了系统的分析。从2014年到2023年,在WebofScience(WOS)上搜索了与“马铃薯”和“疾病”相关的出版物。结果显示,共检索到2095篇有关马铃薯病害的出版物,年度出版物产量以8.52%的增长率逐年增长。发行出版物的主要国家是美国,中国,和印度。观察到中国之间有相对密切的合作,美国,和英国在国际合作方面,而印度的国际合作不那么广泛。基于引文分析和趋势主题,未来潜在的研究方向包括纳米粒子,由于其尺寸小,为生物活性物质提供了高效的载体,广泛的表面积,和许多绑定站点;机器学习,这有助于快速识别大量数据集中的相关目标,从而加速疾病诊断和杀菌剂创新的过程;以及由各种功能微生物组成的合成群落,在疾病预防和控制方面表现出更稳定的效果。
    Research on potato diseases had been widely reported, but a systematic review of potato diseases was lacking. Here, bibliometrics was used to systematically analyze the progress of potato disease. The publications related to \"potato\" and \"disease\" were searched in the Web of Science (WOS) from 2014 to 2023. The results showed that a total of 2095 publications on potato diseases were retrieved, with the annual publication output increasing year by year at a growth rate of 8.52%. The main countries where publications were issued were the United States, China, and India. There was relatively close cooperation observed between China, the United States, and the United Kingdom in terms of international collaboration, while international cooperation by India was less extensive. Based on citation analysis and trending topics, potential future research directions include nanoparticles, which provides highly effective carriers for biologically active substances due to their small dimensions, extensive surface area, and numerous binding sites; machine learning, which facilitates rapid identification of relevant targets in extensive datasets, thereby accelerating the process of disease diagnosis and fungicide innovation; and synthetic communities composed of various functional microorganisms, which demonstrate more stable effects in disease prevention and control.

    疟疾仍然是一个全球性的公共卫生问题,尽管它已经从许多国家消除。斯里兰卡和中国是最近获得消除疟疾地位的两个国家,东南亚的许多国家目前正在筹备到2030年实现同样的目标。然而,诺氏疟原虫,一种非人类灵长类疟疾寄生虫继续对该地区的公众健康构成威胁,感染了除东帝汶以外的东南亚所有国家的许多人。此外,其他非人灵长类疟疾寄生虫,如食蟹性疟原虫和疟原虫感染该地区的人类。非人灵长类动物,携带这些寄生虫的长尾和猪尾猕猴现在在村庄附近的农场和森林边缘越来越普遍。此外,这些地区也存在属于Lecuosphhyrus组的按蚊,这使得它们非常适合传播非人灵长类疟疾寄生虫。随着景观的变化和森林的砍伐,随着人类疟疾的消除,非人灵长类疟疾寄生虫将在未来几年影响更多的人类。也许是因为失去了豁免权,更多的人将被感染,目前在马来西亚被证明。因此,需要迅速采取控制措施,以在2030年之前实现消除疟疾的状态。然而,寄生虫的人畜共患起源和媒介行为对早期叮咬的变化似乎是该地区消除疟疾努力的绊脚石。在这次审查中,我们讨论了由于森林砍伐而消除疟疾所面临的挑战以及非人类灵长类动物疟疾寄生虫构成的严重威胁。
    Malaria continues to be a global public health problem although it has been eliminated from many countries. Sri Lanka and China are two countries that recently achieved malaria elimination status, and many countries in Southeast Asia are currently in the pipeline for achieving the same goal by 2030. However, Plasmodium knowlesi, a non-human primate malaria parasite continues to pose a threat to public health in this region, infecting many humans in all countries in Southeast Asia except for Timor-Leste. Besides, other non-human primate malaria parasite such as Plasmodium cynomolgi and Plasmodium inui are infecting humans in the region. The non-human primates, the long-tailed and pig-tailed macaques which harbour these parasites are now increasingly prevalent in farms and forest fringes close by to the villages. Additionally, the Anopheles mosquitoes belonging to the Lecuosphyrus Group are also present in these areas which makes them ideal for transmitting the non-human primate malaria parasites. With changing landscape and deforestation, non-human primate malaria parasites will affect more humans in the coming years with the elimination of human malaria. Perhaps due to loss of immunity, more humans will be infected as currently being demonstrated in Malaysia. Thus, control measures need to be instituted rapidly to achieve the malaria elimination status by 2030. However, the zoonotic origin of the parasite and the changes of the vectors behaviour to early biting seems to be the stumbling block to the malaria elimination efforts in this region. In this review, we discuss the challenges faced in malaria elimination due to deforestation and the serious threat posed by non-human primate malaria parasites.

    白血病沙蝇是利什曼病的唯一确认媒介,西班牙等南欧国家的一组地方病和重新出现的疾病。光陷阱是目前正在使用的主要监视方法。然而,沙蝇对颜色光的吸引力仍然是未知的。根据先前的研究,UV-LED光源的效果,并采用改进的Flebocycollect(FC)光阱模型评估了其与不同颜色光的协同作用。结果表明,与商业CDC(疾病控制和预防中心)陷阱相比,雌性PerniciosusPhlebotomussand蝇更容易被蓝色和UVLED光源组合所吸引的FC陷阱所吸引(Bonferronipost-hoc测试;p<0.08;蓝色/UV平均值=0.50;CDC平均值=0.13),而红色和紫外线修饰的陷阱的组合在捕获小型沙蝇方面表现出色(Bonferronipost-hoc检验;p<0.04;蓝色/紫外线平均值=1.19;CDC平均值=0.66)。然而,根据我们之前的研究,将紫外线光源整合到沙蝇陷阱中似乎并没有增强它们的吸引力,因为它没有导致更高的捕获率。.这些发现有助于理解沙蝇的视觉和光色检测。建议进一步研究以标准化圈闭施工程序,并根据不同的沙蝇种类探索不同特有地区的变化。
    Phlebotomine sand flies are the sole confirmed vector of leishmaniosis, a group of endemic and re-emerging diseases in southern European countries such as Spain. Light traps are the major surveillance method currently being employed. Nevertheless, color light attraction by sand flies remains mostly unknown. Following prior research, the effect of UV-LED light sources, and its synergic effect with different color lights has been evaluated employing a modified Flebocollect (FC) light trap model. Results suggest that female Phlebotomus perniciosus sand flies are more attracted to a FC trap lured with the combination of blue and UV LED light sources than commercial CDC (Center for Disease Control and prevention) traps (Bonferroni post-hoc test; p < 0.08; blue/UV mean = 0.50; CDC mean = 0.13), while the combination of red and UV modified-traps excel in capturing Sergentomyia minuta sand flies (Bonferroni post-hoc test; p < 0.04; blue/UV mean = 1.19; CDC mean = 0.66). However, based on our prior studies, incorporating UV light sources into sand fly traps does not seem to enhance their attractiveness, as it has not resulted in higher capture rates. These findings contribute to understanding how sand flies\' vision and light color detection is. Further research is recommended to standardize trap construction procedures and explore variations in different endemic regions according to different sand fly species.

    背景:结核病是仅次于COVID-19的第二大致命传染病,也是全球第13大死亡原因。在结核病高负担的30个国家中,中国在结核病病例估计数量中排名第三。中国是结核病战略计划资金短缺的75个国家中的前四名。为了降低成本,提高中国结核病治疗的效果,NHSA开发了一种创新的BP方法。本研究旨在模拟这种支付方式对不同利益相关者的影响,减轻结核病患者的经济负担,提高医疗服务质量,促进政策优化,并为医疗保健支付改革提供了一个模型,可以被世界各地的其他地区参考。
    方法:我们开发了一个基于决策树分析的模拟模型,以预测支付方式对不同利益相关者的潜在财务影响的预期效果。我们的分析主要集中在比较试点地区接受Medicare的结核病患者BPs前后的医疗保健费用变化。用于分析的数据包括健康保险机构2019-2021年的结核病服务索赔记录,当地疾病控制中心的结核病患病率数据,和医疗保健设施的收入和支出数据来自统计年鉴。使用蒙特卡罗随机模拟模型来估计结果。
    结果:采用创新的BP方法后,每年每个结核病患者,估计每年的总支出将从2,523.28美元减少到2,088.89美元,减少了434.39美元(17.22%)。结核病患者的自付支出预计将从$1,249.02减少到$1,034.00,减少了$215.02(17.22%)。医疗保健提供者的收入从2,523.28美元减少到2,308.26美元,但医疗保健提供者/机构的收入支出比率从-6.09%增加到9.50%。
    结论:本研究强调了BPs改善医疗结果和控制结核病治疗相关费用的潜力。展示了其在加强医疗服务的协调性和可持续性方面的可行性和优势,从而为全球医疗支付改革提供有价值的见解。
    BACKGROUND: Tuberculosis is the second most deadly infectious disease after COVID-19 and the 13th leading cause of death worldwide. Among the 30 countries with a high burden of TB, China ranks third in the estimated number of TB cases. China is in the top four of 75 countries with a deficit in funding for TB strategic plans. To reduce costs and improve the effectiveness of TB treatment in China, the NHSA developed an innovative BP method. This study aimed to simulate the effects of this payment approach on different stakeholders, reduce the economic burden on TB patients, improve the quality of medical services, facilitate policy optimization, and offer a model for health care payment reforms that can be referenced by other regions throughout the world.
    METHODS: We developed a simulation model based on a decision tree analysis to project the expected effects of the payment method on the potential financial impacts on different stakeholders. Our analysis mainly focused on comparing changes in health care costs before and after receiving BPs for TB patients with Medicare in the pilot areas. The data that were used for the analysis included the TB service claim records for 2019-2021 from the health insurance agency, TB prevalence data from the local Centre for Disease Control, and health care facilities\' revenue and expenditure data from the Statistic Yearbook. A Monte Carlo randomized simulation model was used to estimate the results.
    RESULTS: After adopting the innovative BP method, for each TB patient per year, the total annual expenditure was estimated to decrease from $2,523.28 to $2,088.89, which is a reduction of $434.39 (17.22%). The TB patient out-of-pocket expenditure was expected to decrease from $1,249.02 to $1,034.00, which is a reduction of $215.02 (17.22%). The health care provider\'s revenue decreased from $2,523.28 to $2,308.26, but the health care provider/institution\'s revenue-expenditure ratio increased from -6.09% to 9.50%.
    CONCLUSIONS: This study highlights the potential of BPs to improve medical outcomes and control the costs associated with TB treatment. It demonstrates its feasibility and advantages in enhancing the coordination and sustainability of medical services, thus offering valuable insights for global health care payment reform.

    背景:为了研究COVID-19大流行对死亡率的影响,我们估计了24个国家2020年和2021年的超额全因死亡率,总体上按性别和年龄分层.
    方法:总计,收集了2015-2021年的特定年龄和特定性别的每周全因死亡率,并通过比较2020年和2021年的每周年龄标准化死亡率与预期死亡率来计算2020年和2021年的超额死亡率,根据历史数据(2015-2019年)估计,考虑季节性,以及长期和短期的趋势。使用粗死亡率类似地计算特定年龄的每周超额死亡率。使用简单和多水平回归模型研究了国家和大流行相关变量与超额死亡率的关系。
    结果:在奥地利发现了2020年和2021年的超额累计死亡率,巴西,比利时,塞浦路斯,英格兰和威尔士,爱沙尼亚,法国,格鲁吉亚,希腊,以色列,意大利,哈萨克斯坦,毛里求斯,北爱尔兰,挪威,秘鲁,波兰,斯洛文尼亚,西班牙,瑞典,乌克兰,和美国。澳大利亚和丹麦仅在2021年经历了超额死亡率。在这两年中,毛里求斯的全因死亡率在统计上显着下降。COVID-19的每周发病率与两年的超额死亡率显著正相关,但随着完全接种疫苗的人口百分比的增加,正相关在2021年减弱。控制措施的严谨性指数分别与2020年和2021年的超额死亡率呈正相关和负相关。
    结论:这项研究提供了证据,表明在大流行的头2年中,大多数国家的死亡率都在大幅增加,控制措施的严格性和疫苗接种率在确定超额死亡率的幅度方面相互作用。
    BACKGROUND: To examine the impact of the COVID-19 pandemic on mortality, we estimated excess all-cause mortality in 24 countries for 2020 and 2021, overall and stratified by sex and age.
    METHODS: Total, age-specific and sex-specific weekly all-cause mortality was collected for 2015-2021 and excess mortality for 2020 and 2021 was calculated by comparing weekly 2020 and 2021 age-standardised mortality rates against expected mortality, estimated based on historical data (2015-2019), accounting for seasonality, and long-term and short-term trends. Age-specific weekly excess mortality was similarly calculated using crude mortality rates. The association of country and pandemic-related variables with excess mortality was investigated using simple and multilevel regression models.
    RESULTS: Excess cumulative mortality for both 2020 and 2021 was found in Austria, Brazil, Belgium, Cyprus, England and Wales, Estonia, France, Georgia, Greece, Israel, Italy, Kazakhstan, Mauritius, Northern Ireland, Norway, Peru, Poland, Slovenia, Spain, Sweden, Ukraine, and the USA. Australia and Denmark experienced excess mortality only in 2021. Mauritius demonstrated a statistically significant decrease in all-cause mortality during both years. Weekly incidence of COVID-19 was significantly positively associated with excess mortality for both years, but the positive association was attenuated in 2021 as percentage of the population fully vaccinated increased. Stringency index of control measures was positively and negatively associated with excess mortality in 2020 and 2021, respectively.
    CONCLUSIONS: This study provides evidence of substantial excess mortality in most countries investigated during the first 2 years of the pandemic and suggests that COVID-19 incidence, stringency of control measures and vaccination rates interacted in determining the magnitude of excess mortality.

    Biochar has been widely used in soil amendment and environmental remediation. Polycyclic aromatic hydrocarbons (PAHs) could be produced in preparation of biochar, which may pose potential risks to the environment and human health. At present, most studies focus on the ecotoxicity potential of biochar, while there are few systematic reviews on the formation mechanisms and mitigation strategies of PAHs in biochar. Therefore, a systematical understanding of the distribution, formation mechanisms, risk assessment, and degradation approaches of PAHs in biochar is highly needed. In this paper, the distribution and content of the total and bioavailable PAHs in biochar are reviewed. Then the formation mechanisms, influencing factors, and potential risk assessment of PAHs in biochar are systematically explored. After that, the effective strategies to alleviate PAHs in biochar are summarized. Finally, suggestions and perspectives for future studies are proposed. This review provides a guide for reducing the formation of biochar-associated PAHs and their toxicity, which is beneficial for the development and large-scale safe use of environmentally friendly biochar.

    重金属(HM)污染对植物生长和人类健康的威胁越来越大,烟草由于其出色的吸收能力而成为高度脆弱的植物。烟草的广泛种植加剧了这些担忧,随着HMs在全球烟草种植土壤中越来越普遍,对人类健康构成了更大的风险。这些金属的吸收不仅会阻碍烟草的生长和质量,还会加剧吸烟对健康的危害。实施主动策略以最大程度地减少烟草中的HM吸收是至关重要的。各种方法,包括化学固定,转基因修饰,农艺调整,和微生物干预,已证明在遏制HM积累和减轻相关不利影响方面是有效的。然而,阐明这些控制策略及其机制的全面审查仍然明显缺乏。本文旨在通过研究烟草暴露对烟草植物和人类健康的有害影响来填补这一空白。此外,它为降低烟草中HM含量的机制提供了彻底的探索。该审查巩固和综合了最近旨在减少烟草中HM含量的国内和国际举措,全面概述他们的现状,好处,和限制。
    The threat of heavy metal (HM) pollution looms large over plant growth and human health, with tobacco emerging as a highly vulnerable plant due to its exceptional absorption capacity. The widespread cultivation of tobacco intensifies these concerns, posing increased risks to human health as HMs become more pervasive in tobacco-growing soils globally. The absorption of these metals not only impedes tobacco growth and quality but also amplifies health hazards through smoking. Implementing proactive strategies to minimize HM absorption in tobacco is of paramount importance. Various approaches, encompassing chemical immobilization, transgenic modification, agronomic adjustments, and microbial interventions, have proven effective in curbing HM accumulation and mitigating associated adverse effects. However, a comprehensive review elucidating these control strategies and their mechanisms remains notably absent. This paper seeks to fill this void by examining the deleterious effects of HM exposure on tobacco plants and human health through tobacco consumption. Additionally, it provides a thorough exploration of the mechanisms responsible for reducing HM content in tobacco. The review consolidates and synthesizes recent domestic and international initiatives aimed at mitigating HM content in tobacco, delivering a comprehensive overview of their current status, benefits, and limitations.
