1航空微波遥感观测海水表层盐度的研究进展显示文摘盐度是海水的基本特征之一。在开敞海和海岸带进行长期的盐度测量具有重要的意义。利用航空微波技术观测海水盐度的研究始于20世纪60年代末,经过20多年的不断探索,近10年来这一技术研究有了较大的进展。将被动式微波辐射计装在小型飞机上对海水表层盐度进行观测,可以获得同步、快速和大面积的海水表层盐度。目前,已有多种微波辐射计在不同国家和地区的河口海湾和海洋得到使用,如ESTAR、SLFMR、STARRS、PALS和PLMR。使用航空遥感辐射计对海水进行观测,目前,校正后的盐度当分辨率为1 km2时数据准确度和精度都可以达到1psu。利用最新研发的双偏光微波航空遥感技术有望使校正后的盐度数值精度和准确度控制在1psu以内。王永红 M L Heron Peter Ridd 2007海洋地质与第四纪地质2007,27,1:5
2Approach to identifying research gaps on vector-borne and other infectious diseases of poverty in urban settings:scoping review protocol from the VERDAS consortium and reflections on the project’s implementation显示文摘Background:This paper presents the overall approach undertaken by the“VEctor boRne DiseAses Scoping reviews”(VERDAS)consortium in response to a call issued by the Vectors,Environment and Society unit of the Special Programme for Research and Training in Tropical Diseases hosted by the World Health Organization.The aim of the project was to undertake a broad knowledge synthesis and identify knowledge gaps regarding the control and prevention of vector-borne diseases in urban settings.Methods:The consortium consists of 14 researchers,13 research assistants,and one research coordinator from seven different institutions in Canada,Colombia,Brazil,France,Spain,and Burkina Faso.A six-step protocol was developed for the scoping reviews undertaken by the consortium,based on the framework developed by Arksey and O’Malley and improved by Levac et al.In the first step,six topics were identified through an international eDelphi consultation.In the next four steps,the scoping reviews were conducted.The sixth step was the VERDAS workshop held in Colombia in March 2017.Discussion:In this article,we discuss several methodological issues encountered and share our reflections on this work.We believe this protocol provides a strong example of an exhaustive and rigorous process for performing broad knowledge synthesis for any given topic and should be considered for future research initiatives and donor agendas in multiple fields to highlight research needs scientifically.Stephanie Degroote Clara Bermudez-Tamayo Valery Ridde 2018Infectious Diseases of Poverty2018,7,1:4
3Priorities and needs for research on urban interventions targeting vector-borne diseases: rapid review of scoping and systematic reviews显示文摘This paper highlights the critical importance of evidence on vector-borne diseases(VBD)prevention and control interventions in urban settings when assessing current and future needs,with a view to setting policy priorities that promote inclusive and equitable urban health services.Research should produce knowledge about policies and interventions that are intended to control and prevent VBDs at the population level and to reduce inequities.Such interventions include policy,program,and resource distribution approaches that address the social determinants of health and exert influence at organizational and system levels.Clara Bermudez-Tamayo Olive Mukamana Mabel Carabali Lyda Osorio Florence Fournet Kounbobr Roch Dabiré Celina Turchi Marteli Adolfo Contreras Valéry Ridde 2016Infectious Diseases of Poverty2016,5,1:3
4A scoping review on the field validation and implementation of rapid diagnostic tests for vector-borne and other infectious diseases of poverty in urban areas显示文摘Background:Health personnel face challenges in diagnosing vector-borne and other diseases of poverty in urban settings.There is a need to know what rapid diagnostic technologies are available,have been properly assessed,and are being implemented to improve control of these diseases in the urban context.This paper characterizes evidence on the field validation and implementation in urban areas of rapid diagnostics for vector-borne diseases and other diseases of poverty.Main body:A scoping review was conducted.Peer-reviewed and grey literature were searched using terms describing the targeted infectious diseases,diagnostics evaluations,rapid tests,and urban setting.The review was limited to studies published between 2000 and 2016 in English,Spanish,French,and Portuguese.Inclusion and exclusion criteria were refined post hoc to identify relevant literature regardless of study design and geography.A total of 179 documents of the 7806 initially screened were included in the analysis.Malaria(n=100)and tuberculosis(n=47)accounted for the majority of studies that reported diagnostics performance,impact,and implementation outcomes.Fewer studies,assessing mainly performance,were identified for visceral leishmaniasis(n=9),filariasis and leptospirosis(each n=5),enteric fever and schistosomiasis(each n=3),dengue and leprosy(each n=2),and Chagas disease,human African trypanosomiasis,and cholera(each n=1).Reported sensitivity of rapid tests was variable depending on several factors.Overall,specificities were high(>80%),except for schistosomiasis and cholera.Impact and implementation outcomes,mainly acceptability and cost,followed by adoption,feasibility,and sustainability of rapid tests are being evaluated in the field.Challenges to implementing rapid tests range from cultural to technical and administrative issues.Conclusions:Rapid diagnostic tests for vector-borne and other diseases of poverty are being used in the urban context with demonstrated impact on case detection.However,most evidence comes from malaria rapid diagnostics,with variable results.While rapid tests for tuberculosis and visceral leishmaniasis require further implementation studies,more evidence on performance of current tests or development of new alternatives is needed for dengue,Chagas disease,filariasis,leptospirosis,enteric fever,human African trypanosomiasis,schistosomiasis and cholera.Lyda Osorio Jonny Alejandro Garcia Luis Gabriel Parra Victor Garcia Laura Torres Stephanie Degroote Valery Ridde 2018Infectious Diseases of Poverty2018,7,1:2
5Presence of three dengue serotypes in Ouagadougou(Burkina Faso):research and public health implications显示文摘Background:The significant malaria burden in Africa has often eclipsed other febrile illnesses.Burkina Faso’s first dengue epidemic occurred in 1925 and the most recent in 2013.Yet there is still very little known about dengue prevalence,its vector proliferation,and its poverty and equity impacts.Methods:An exploratory cross-sectional survey was performed from December 2013 to January 2014.Six primary healthcare centers in Ouagadougou were selected based on previously reported presence of Flavivirus.All patients consulting with fever or having had fever within the previous week and with a negative rapid diagnostic test(RDT)for malaria were invited to participate.Sociodemographic data,healthcare use and expenses,mobility,health-related status,and vector control practices were captured using a questionnaire.Blood samples of every eligible subject were obtained through finger pricks during the survey for dengue RDT using SD BIOLINE Dengue Duo(NS1Ag and IgG/IgM)®and to obtain blood spots for reverse transcription polymerase chain reaction(RT-PCR)analysis.In a sample of randomly selected yards and those of patients,potential Aedes breeding sites were found and described.Larvae were collected and brought to the laboratory to monitor the emergence of adults and identify the species.Results:Of the 379 subjects,8.7%(33/379)had positive RDTs for dengue.Following the 2009 WHO classification,38.3%(145/379)had presumptive,probable,or confirmed dengue,based on either clinical symptoms or laboratory testing.Of 60 samples tested by RT-PCR(33 from the positive tests and 27 from the subsample of negatives),15 were positive.The serotypes observed were DENV2,DENV3,and DENV4.Odds of dengue infection in 15-to-20-year-olds and persons over 50 years were 4.0(CI 95%:1.0–15.6)and 7.7(CI 95%:1.6–37.1)times higher,respectively,than in children under five.Average total spending for a dengue episode was 13771 FCFA[1300–67300 FCFA](1$US=478 FCFA).On average,2.6 breeding sites were found per yard.Potential Aedes breeding sites were found near 71.4%(21/28)of patients,but no adult Aedes were found.The most frequently identified potential breeding sites were water storage containers(45.2%).Most specimens collected in yards were Culex(97.9%).Conclusions:The scientific community,public health authorities,and health workers should consider dengue as a possible cause of febrile illness in Burkina Faso.Valéry Ridde Isabelle Agier Emmanuel Bonnet Mabel Carabali Kounbobr Roch Dabiré Florence Fournet Antarou Ly Ivlabèhiré Bertrand Meda Beatriz Parra 2016Infectious Diseases of Poverty2016,5,1:2
6Scoping review on vector-borne diseases in urban areas:transmission dynamics,vectorial capacity and co-infection显示文摘Background:Transmission dynamics,vectorial capacity,and co-infections have substantial impacts on vector-borne diseases(VBDs)affecting urban and suburban populations.Reviewing key factors can provide insight into priority research areas and offer suggestions for potential interventions.Main body:Through a scoping review,we identify knowledge gaps on transmission dynamics,vectorial capacity,and co-infections regarding VBDs in urban areas.Peer-reviewed and grey literature published between 2000 and 2016 was searched.We screened abstracts and full texts to select studies.Using an extraction grid,we retrieved general data,results,lessons learned and recommendations,future research avenues,and practice implications.We classified studies by VBD and country/continent and identified relevant knowledge gaps.Of 773 articles selected for full-text screening,50 were included in the review:23 based on research in the Americas,15 in Asia,10 in Africa,and one each in Europe and Australia.The largest body of evidence concerning VBD epidemiology in urban areas concerned dengue and malaria.Other arboviruses covered included chikungunya and West Nile virus,other parasitic diseases such as leishmaniasis and trypanosomiasis,and bacterial rickettsiosis and plague.Most articles retrieved in our review combined transmission dynamics and vectorial capacity;only two combined transmission dynamics and co-infection.The review identified significant knowledge gaps on the role of asymptomatic individuals,the effects of co-infection and other host factors,and the impacts of climatic,environmental,and socioeconomic factors on VBD transmission in urban areas.Limitations included the trade-off from narrowing the search strategy(missing out on classical modelling studies),a lack of studies on co-infections,most studies being only descriptive,and few offering concrete public health recommendations.More research is needed on transmission risk in homes and workplaces,given increasingly dynamic and mobile populations.The lack of studies on co-infection hampers monitoring of infections transmitted by the same vector.Conclusions:Strengthening VBD surveillance and control,particularly in asymptomatic cases and mobile populations,as well as using early warning tools to predict increasing transmission,were key strategies identified for public health policy and practice.Marcus Eder Fanny Cortes Noemia Teixeira de Siqueira Filha Giovanny Vinicius Araujo de Franca Stephanie Degroote Cynthia Braga Valery Ridde Celina Maria Turchi Martelli 2018Infectious Diseases of Poverty2018,7,1:2
