1193nmLA-ICPMS对国际地质标准参考物质中42种主量和微量元素的分析显示文摘本文采用配备有 193nm Ar F准分子 (excimer)激光器的 Geo L as2 0 0 M剥蚀系统和 Elan6 10 0 DRC ICP- MS对 4个美国地质调查所 (USGS)玻璃标准参考物质以及 3个美国国家标准技术研究院 (NIST)人工合成硅酸盐玻璃标准参考物质中几乎覆盖整个质量数范围 (从 7L i到 2 38U)的 38个微量和 4个主量 (Na、Mg、Ti和 Mn)元素进行了分析。分析结果表明 ,无论是对 USGS还是 NIST玻璃 ,元素分析的相对标准偏差 RSDs和分析值与参考值之间的相对偏差 (RDs)一般优于 10 % ,RSD和RD较大的元素主要出现在含量很低或不均匀样品中。稀土元素的 RSD显示 ,除 AGV- 2 G可能存在不均匀现象外 ,其它所测样品在 6 0 μm尺度上 ,元素分布是均匀的。本研究证明 ,由于 ICP- MS具有 10 8cps(每秒计数 )的动态线性范围 ,本实验室的L A- ICPMS系统可定量分析含量在百分之几的主量元素及微量元素。分析精密度和准确度可与常规溶液雾化进样 ICP-柳小明 高山 袁洪林 Bodo HATTENDORF DetlefG■NTHER 陈亮 胡圣红 2002岩石学报2002,18,3:153
2The impact of pastoralist mobility on tuberculosis control in Ethiopia:a systematic review and meta-synthesis显示文摘Background:Directly observed treatment,short-course(DOTS)is the current mainstay to control tuberculosis(TB)worldwide.Context-specific adaptations of DOTS have impending implications in the fight against TB.In Ethiopia,there is a national TB control programme with the goal to eliminate TB,but uneven distribution across lifestyle gradients remains a challenge.Notably,the mobile pastoralist communities in the country are disproportionately left uncovered.The aim of this study was to summarize the evidence base from published literature to guide TB control strategy for mobile pastoralist communities in Ethiopia.Main text:We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA)guidelines and systematically reviewed articles in seven electronic databases:Excerptra Medical Database,African Journal Online,PubMed,Google Scholar,Centre for Agriculture and Bioscience International Direct,Cochrane Library and Web of Science.The databases were searched from inception to December 31,2018,with no language restriction.We screened 692 items of which 19 met our inclusion criteria.Using a meta-ethnographic method,we identified six themes:(i)pastoralism in Ethiopia;(ii)pastoralists’livelihood profile;(iii)pastoralists’service utilisation;(iv)pastoralists’knowledge and awareness on TB control services;(v)challenges of TB control in pastoral settings;and(vi)equity disparities affecting pastoralists.Our interpretation triangulates the results across all included studies and shows that TB control activities observed in pastoralist regions of Ethiopia are far fewer than elsewhere in the country.Conclusions:This systematic review and meta-synthesis shows that TB control in Ethiopia does not align well with the pastoralist lifestyle.Inaccessibility and lack of acceptability of TB care are the key bottlenecks to pastoralist TB service provision.Targeting these two parameters holds promise to enhance effectiveness of an intervention.Faisal Nooh Lisa Crump Abdiwahab Hashi Rea Tschopp Esther Schelling Klaus Reither Jan Hattendorf Seid M.Ali Brigit Obrist Jurg Utzinger Jakob Zinsstag 2019Infectious Diseases of Poverty2019,8,5:2

15Ecological and behavioural risk factors of scrub typhus in central Vietnam:a case-control study显示文摘Background The risk factors for scrub typhus in Vietnam remain unknown.Scrub typhus caused by Orientia tsutsugamushi often presents as an undifferentiated febrile illness and remains under appreciated due to the limited availability of diagnostic tests.This tropical rickettsial illness is increasingly recognized as an important cause of non-malaria acute undifferentiated fever in Asia.This study aimed to investigate behavioural and ecological related risk factors of scrub typhus to prevent this potentially life-threatening disease in Vietnam.Methods We conducted a clinical hospital-based active surveillance study,and a retrospective residence-enrolment date-age-matched case–control study in Khanh Hoa province,Vietnam,from August 2018 to March 2020.Clinical examinations,polymerase chain reaction and enzyme-linked immunosorbent assay IgM tests were applied to define cases and controls.All enrolled participants filled out a questionnaire including demographic socio-economic status,personal behaviors/protective equipment,habitat connections,land use,and possible exposure to the vector.Multivariable conditional logistic regression was used to define the scrub typhus associated risk factors.Results We identified 44 confirmed cases and matched them with 152 controls.Among cases and controls,the largest age group was the 41–50 years old and males accounted for 61.4%and 42.8%,respectively.There were similarities in demographic characteristics between the two groups,with the exception of occupation.Several factors were significantly associated with acquisition of scrub typhus,including sitting/laying directly on household floor[adjusted OR(aOR)=4.9,95%CI:1.6–15.1,P=0.006],household with poor sanitation/conditions(aOR=7.9,95%CI:1.9–32.9,P=0.005),workplace environment with risk(aOR=3.0,95%CI:1.2–7.6,P=0.020),always observing mice around home(aOR=3.7,95%CI:1.4–9.9,P=0.008),and use of personal protective equipment in the field(aOR=0.4,95%CI:0.1–1.1,P=0.076).Conclusions Ecological and household hygiene-related factors were more associated with scrub typhus infection,than individual-level exposure activities in the hyper-endemic area.These findings support local education and allow people to protect themselves from scrub typhus,especially in areas with limitations in diagnostic capacity.Hanh Thi Duc Tran Jan Hattendorf Hung Manh Do Thanh Tien Hoang Hang Thi Hai Hoang Hoa Ngoc Lam Mai Kim Huynh Lan Thi Hoang Vu Jakob Zinsstag Daniel Henry Paris Esther Schelling 2021Infectious Diseases of Poverty2021,10,4:1
