2Malaria over-diagnosis in Cameroon:diagnostic accuracy of Fluorescence and Staining Technologies(FAST)Malaria Stain and LED microscopy versus Giemsa and bright field microscopy validated by polymerase chain reaction显示文摘Background:Malaria is a major world health issue and its continued burden is due,in part,to difficulties in the diagnosis of the illness.The World Health Organization recommends confirmatory testing using microscopy-based techniques or rapid diagnostic tests(RDT)for all cases of suspected malaria.In regions where Plasmodium species are indigenous,there are multiple etiologies of fever leading to misdiagnoses,especially in populations where HIV is prevalent and children.To determine the frequency of malaria infection in febrile patients over an 8-month period at the Regional Hospital in Bamenda,Cameroon,we evaluated the clinical efficacy of the Flourescence and Staining Technology(FAST)Malaria stain and ParaLens AdvanceTM microscopy system(FM)and compared it with conventional bright field microscopy and Giemsa stain(GS).Methods:Peripheral blood samples from 522 patients with a clinical diagnosis of“suspected malaria”were evaluated using GS and FM methods.A nested PCR assay was the gold standard to compare the two methods.PCR positivity,sensitivity,specificity,positive predictive value(PPV),and negative predictive value(NPV)were determined.Results:Four hundred ninety nine samples were included in the final analysis.Of these,30 were positive via PCR(6.01%)with a mean PPV of 19.62%and 27.99%for GS and FM,respectively.The mean NPV was 95.01%and 95.28%for GS and FM,respectively.Sensitivity was 26.67%in both groups and specificity was 92.78%and 96.21%for GS and FM,respectively.An increased level of diagnostic discrepancy was observed between technicians based upon skill level using GS,which was not seen with FM.Conclusions:The frequency of malarial infections confirmed via PCR among patients presenting with fever and other symptoms of malaria was dramatically lower than that anticipated based upon physicians’clinical suspicions.A correlation between technician skill and accuracy of malaria diagnosis using GS was observed that was less pronounced using FM.Additionally,FM increased the specificity and improved the PPV,suggesting this relatively low cost approach could be useful in resource-limited environments.Anecdotally,physicians were reluctant to not treat all patients symptomatically before results were known and in spite of a negative microscopic diagnosis,highlighting the need for further physician education to avoid this practice of overtreatment.A larger study in an area with a known high prevalence is being planned to compare the two microscopy methods against available RDTs.Sean M.Parsel Steven A.Gustafson Edward Friedlander Alexander A.Shnyra Aderosoye J.Adegbulu Ying Liu Nicole M.Parrish Syed A.Jamal Eve Lofthus Leo Ayuk Charles Awasom Carolyn J.Henry Carole P.McArthur 2017Infectious Diseases of Poverty2017,6,1:2

20A meta-analysis of 1-year outcomes of transcatheter versus surgical aortic valve replacement in low-risk patients with severe aortic stenosis显示文摘Background Transcatheter aortic valve replacement(TAVR)for the treatment symptomatic severe aortic stenosis(AS)is indicated in patients with intermediate or higher surgical risk.Latest trials showed TAVR,and surgical aortic valve replacement(SAVR)perform similarly at 1-year for the composite outcomes of mortality,stroke and rehospitalization.We performed a comprehensive meta-analysis to compare individual outcomes at 1-year for TAVR compared to SAVR in low-risk patients.Methods Pub Med,Embase,and Cochrane central were searched for all the randomized controlled trials(RCTs)that reported 1-year comparative outcomes of TAVR and surgical aortic valve replacement(SAVR).Our conclusions are based upon the random-effects model using Der Simonian-Laird estimator.Results Data from 4 trials and 2887 randomized patients showed that TAVR had lower rates of all-cause mortality,cardiovascular mortality,and atrial fibrillation compared to SAVR at 1-year follow-up(P<0.05 for all).Also,TAVR was also associated with a significantly higher risk of permanent pacemaker implantation and moderate-severe paravalvular leak(P<0.05).Conclusions The latest randomised trial data demonstrates that in short-term,TAVR is safe and effective in reducing all-cause mortality or stroke.Longer follow-up of RCTs is needed to determine the durability of clinical benefits in TAVR over SAVR in low-risk patients.Aaqib H Malik Syed Zaid Hasan Ahmad Joshua Goldberg Tanya Dutta Cenap Undemir Martin Cohen Wilbert S Aronow Steven L Lansman 2020Journal of Geriatric Cardiology2020,17,1:0
