Abstract Background and Objectives Nucleic acid amplification testing (NAT), in blood services context, is used for the detection of viral parasite nucleic acids to reduce transfusion‐transmitted infections. This project reviewed NAT screening donations globally. Materials Methods A survey on usage, developed by International Society Blood Transfusion Working Party Transfusion‐transmitted Infectious Diseases (ISBT WP‐TTID), was distributed through ISBT WP‐TTID members. Data were analysed...
The Sysmex XN-1000 cellular hematology analyzers, widely used in Burkina Faso, can provide information on Plasmodium infection with the "iRBC?" flag triggered during a blood count. This study aims to evaluate contribution of this alarm diagnostic orientation malaria an endemic area. samples were collected between August and September 2023. was sampled EDTA tubes count performed XN-1000. XN-31 as reference method for identification falciparum species. Identification non-falciparum species...
A double aortic arch is a rare vascular anomaly. However, this the most common cause of symptomatic ring malformation due to absence involution caudal dorsal aorta. It involves complete encirclement and compression trachea esophagus. The disease usually begins show itself in very early clinical signs, already detectable neonatal period. may lead significant morbidity for patient, wide range symptoms ranging from life-threatening no can be resulting; regardless, their detection extremely...
Introduction: In Sub-Saharan Africa, the true extent of COVID-19 pandemic is not known due to low number tests performed and large proportion asymptomatic cases in populations. This was a seroprevalence study SARS-CoV-2 antibodies blood donors assess virus circulation Burkina Faso. Methodology: It cross-sectional that included unpaid between March April 2022. A rapid diagnostic test used screen donors' plasma. Adjustment made based on performance evaluated national quality control. Results:...
Presents the design of a predictive controller for decentralized control an irrigation delivery canal. The overall canal is decomposed into single subsystems (pools) separated by structure (gate). are inter-dependent because flow through structures depends on both upstream and downstream water level. In paper, theory used to formulate set local controllers automatic operation gates each pool. scheme presented takes account explicitly interactions among subsystems. objective maintain end...
Abstract We have investigated the phytoplankton dynamics of Senegalo‐Mauritanian upwelling region, which is a very productive by processing 13 year set SeaWiFS satellite ocean‐color measurements using PHYSAT‐like method. clustered spectra normalized reflectance (reflectance dependent on chlorophyll‐ concentration only) into 10 significant spectral classes Self‐Organized Map (SOM) associated with hierarchical ascendant classification (HAC). By analyzing climatology these classes, we been able...
Geographical distribution of ABO and RHD antigens is important for blood transfusion services population genetics studies. There are few data on this topic in Burkina Faso, a multi-ethnic country. Our study aims at reporting phenotypic allelic frequencies groups among voluntary donors from various ethnical regions Faso. We conducted cross-sectional including 81,486 donors. were determined using the Bernstein method. Differences assessed chi-square test; p value <0.05 being considered as...
Summary Objectives Our study aimed to update the seroprevalence and factors associated with anti‐dengue virus (DENV) antibody positivity among blood donors discuss their implications for supply. Background Questions on potential transmission of DENV by transfusion increased after documentation risk West Nile virus. This was estimated RNA‐positive units up 37.5%. In Burkina Faso, very few studies in have been conducted. As a result, there were no reliable data allow implementation appropriate...
The Senegalo-Mauritanian upwelling is a very productive occurring along the West coast of Africa. Its seasonal and inter-annual variability south 20degN was analyzed by processing ocean color data sea surface temperature provided satellite sensors. We used classification methodology consisting in neural network topological map hierarchical ascendant classification. Four classes can explain most upwelling. extent maximum February-March, minimum August September. linked to that wind. be...
Background and ObjectiveThe improved performance of serological tests has significantly reduced the risk human immunodeficiency hepatitis B C viruses transmission by blood transfusion, but there is a persistence residual risk. The objective this study was to evaluate impact multiplex PCR in reducing these seronegative donors Burkina Faso.MethodsThis cross-sectional conducted from March September 2017. were performed on sera using ARCHITECTSR i1000 (Abbot diagnosis, USA). Detection viral...
Sub-Saharan African countries face the challenge of immunological transfusion safety that puts many patients at risk post-transfusion hemolytic reactions. This is because pre-transfusion testing for irregular/unexpected antibodies helps to prevent these risks are neither universally available nor accessible. The aim our study was determine prevalence red blood cell alloantibodies and their specificity in transfused Burkina Faso.This a cross-sectional including who had received least one...
Abstract This paper presents an application of optimal control theory to the automatic a single reach irrigation canal. The model used design controller is derived from Saint-Venant's equations discretized through Preiss-man implicit scheme and linearized. A state perturbation observer reconstruct variable reduced number observed variables. Both rejection tracking aspects are considered. tested on both linear nonlinear models prove be efficient.
Considers the design of a decision support system for short term water resource management an irrigation system. The operations similar systems are often impaired by different stochastic events like device failure, heavy rains or dry periods and new long goals. To be effective, such which is based on knowledge techniques (state identification) adaptive optimization (short plans), requires development information demand supply. This gathers data from fields (hydrology, meteorology...
There is a high prevalence of blood-borne infections in West Africa. This study sought to determine the seroprevalence infections, including hepatitis B virus (HBV), C (HCV), HIV, and syphilis, blood donors Burkina Faso. Blood were recruited from 2009 2013 four major cities Faso urban area (Ouagadougou) rural (Bobo Dioulasso, Fada N'Gourma, Ouahigouya). Serology tests surface antigen, anti-HCV, anti-HIV, rapid plasma reagin test used for screening confirmed with ELISA. Disease was calculated...
In Sub-Saharan Africa, transfusion safety remains a challenge due to the high endemicity of blood-borne infections. This study aimed determining seroprevalence human immunodeficiency virus (HIV), hepatitis B (HBV), C (HCV), and Treponema pallidum among blood donors in Ouagadougou. was retrospective donor. HIV 1/2 HCV antibodies HBsAg were screened confirmed with two ELISA (Enzyme Linked ImmunoSorbent Assay). While T. also serology tests. Only samples positive for both tests counted as...
This paper presents the design of a predictive controller for decentralized control an irrigation canal. The overall canal is decomposed into N subsystems (reaches) separated by structure (gate). are interdependent because flow through structures depends on both up- and downstream water levels. Here, theory used to formulate set local controllers automatic operation each reach gate. scheme presented explicitly takes account interactions among subsystems. objective maintain end level at...
