2Aflatoxins,hepatocellular carcinoma and public health显示文摘Hepatocellular carcinoma(HCC) is one of the leading causes of cancer deaths worldwide,primarily affecting populations in the developing countries.Aflatoxin,a food contaminant produced by the fungi Aspergillus flavus and Aspergillus parasiticus,is a known human carcinogen that has been shown to be a causative agent in the pathogenesis of HCC.Aflatoxin can affect a wide range of food commodities including corns,oilseeds,spices,and tree nuts as well as milk,meat,and dried fruit.Many factors affect the growth of Aspergillus fungi and the level of aflatoxin contamination in food.Drought stress is one of the factors that increase susceptibility of plants to Aspergillus and thus aflatoxin contamination.A recent drought is thought to be responsible for finding of trace amounts of aflatoxin in some of the corn harvested in the United States.Although it's too soon to know whether aflatoxin will be a significant problem,since United States is the world's largest corn producer and exporter,this has raised alarm bells.Strict regulations and testing of finished foods and feeds in the United States should prevent a major health scare,and prevent human exposure to deleterious levels of aflatoxin.Unfortunately,such regulations and testing are not in place in many countries.The purpose of this editorial is to summarize the current knowledge on association of aflatoxin and HCC,encourage future research and draw attention to this global public health issue.Arvin Magnussen Mansour A Parsi 2013World Journal of Gastroenterology2013,19,10:16
3酒精摄入、心脏生物标志物和心房颤动风险与不良结局显示文摘酒精摄入和新发心房颤动相关性证据不一,尤其是在低剂量下。该研究评估欧洲队列在整个饮酒范围内酒精摄入、生物标志物和新发心房颤动的关系。方法和结果:在一个以社区为基础的汇集队列中,研究者随访107845人,以评估酒精摄入(酒精种类和饮酒方式)与新发心房颤动的关系。研究者收集经典心血管病危险因素和新发心力衰竭的信息,并检测生物标记物氨基末端脑钠肽前体和高敏肌钙蛋白I。陈嘉睿(译) 练桂丽((审校) Csengeri D Sprünker NA Di Castelnuovo A Niiranen T Vishram-Nielsen JK Costanzo S S derberg S Jensen SM Vartiainen E Donati MB Magnussen C Camen S Gianfagna F L chen ML Kee F Kontto J Mathiesen EB Koenig W Stefan B de Gaetano G J rgensen T Kuulasmaa K Zeller T Salomaa V Iacoviello L Schnabel RB 2021中华高血压杂志2021,29,2:9
4Use of models in large-area forest surveys: comparing model-assisted, model-based and hybrid estimation显示文摘This paper focuses on the use of models for increasing the precision of estimators in large-area forest surveys.It is motivated by the increasing availability of remotely sensed data,which facilitates the development of models predicting the variables of interest in forest surveys.We present,review and compare three different estimation frameworks where models play a core role:model-assisted,model-based,and hybrid estimation.The first two are well known,whereas the third has only recently been introduced in forest surveys.Hybrid inference mixes designbased and model-based inference,since it relies on a probability sample of auxiliary data and a model predicting the target variable from the auxiliary data.We review studies on large-area forest surveys based on model-assisted,modelbased,and hybrid estimation,and discuss advantages and disadvantages of the approaches.We conclude that no general recommendations can be made about whether model-assisted,model-based,or hybrid estimation should be preferred.The choice depends on the objective of the survey and the possibilities to acquire appropriate field and remotely sensed data.We also conclude that modelling approaches can only be successfully applied for estimating target variables such as growing stock volume or biomass,which are adequately related to commonly available remotely sensed data,and thus purely field based surveys remain important for several important forest parameters.Goran Stahl Svetlana Saarela Sebastian Schnell Soren Holm Johannes Breidenbach Sean P.

5儿童期肥胖、成年期肥胖和心血管风险因子显示文摘过去30年,儿童超重或肥胖的发生率明显增加[1]。儿童期肥胖是死亡率增加的预测因子,这主要是由于儿童期肥胖可导致心血管疾病发生率增加。相关的预测研究提示"肥胖流行症"可能改变目前心血管疾病死亡率下降的趋势,使现今儿童的寿命缩短。Juonala M Magnussen CG Berenson GS Venn A Burns TL Sabin MA Srinivasan SR Daniels SR Davis PH Chen W Sun C Cheung M Viikari JS Dwyer T Raitakari OT 叶鹏 2012中华高血压杂志2012,20,1:6
6Comparison of estimators of variance for forest inventories with systematic sampling-results from artificial populations显示文摘Background:Large area forest inventories often use regular grids(with a single random start)of sample locations to ensure a uniform sampling intensity across the space of the surveyed populations.A design-unbiased estimator of variance does not exist for this design.Oftentimes,a quasi-default estimator applicable to simple random sampling(SRS)is used,even if it carries with it the likely risk of overestimating the variance by a practically important margin.To better exploit the precision of systematic sampling we assess the performance of five estimators of variance,including the quasi default.In this study,simulated systematic sampling was applied to artificial populations with contrasting covariance structures and with or without linear trends.We compared the results obtained with the SRS,Matern’s,successive difference replication,Ripley’s,and D’Orazio’s variance estimators.Results:The variances obtained with the four alternatives to the SRS estimator of variance were strongly correlated,and in all study settings consistently closer to the target design variance than the estimator for SRS.The latter always produced the greatest overestimation.In populations with a near zero spatial autocorrelation,all estimators,performed equally,and delivered estimates close to the actual design variance.Conclusion:Without a linear trend,the SDR and DOR estimators were best with variance estimates more narrowly distributed around the benchmark;yet in terms of the least average absolute deviation,Matern’s estimator held a narrow lead.With a strong or moderate linear trend,Matern’s estimator is choice.In large populations,and a low sampling intensity,the performance of the investigated estimators becomes more similar.Steen Magnussen Ronald EMcRoberts Johannes Breidenbach Thomas Nord-Larsen Göran Ståhl Lutz Fehrmann Sebastian Schnell 2020Forest Ecosystems2020,7,2:2
