    Full Text Available Abstract Background Burkina Faso's immunization program has benefited regularly from national and international support. However, national immunization coverage has been irregular, decreasing from 34.7% in 1993 to 29.3% in 1998, and then increasing to 43.9% in 2003. Undoubtedly, a variety of factors contributed to this pattern. This study aims to identify both individual and systemic factors associated with complete vaccination in 1998 and 2003 and relate them to variations in national and international policies and strategies on vaccination of rural Burkinabé children aged 12-23 months. Methods Data from the 1998 and 2003 Demographic and Health Surveys and the Ministry of Health's 1997 and 2002 Statistical Yearbooks, as well as individual interviews with central and regional decision-makers and with field workers in Burkina's healthcare system, were used to carry out a multilevel study that included 805 children in 1998 and 1,360 children in 2003, aged 12-23 months, spread over 44 and 48 rural health districts respectively. Results In rural areas, complete vaccination coverage went from 25.9% in 1998 to 41.2% in 2003. District resources had no significant effect on coverage and the impact of education declined over time. The factors that continued to have the greatest impact on coverage rates were poverty, with its various dimensions, and the utilization of other healthcare services. However, these factors do not explain the persistent differences in complete vaccination between districts. In 2003, despite a trend toward district homogenization, differences between health districts still accounted for a 7.4% variance in complete vaccination. Conclusion Complete vaccination coverage of children is improving in a context of worsening poverty. Education no longer represents an advantage in relation to vaccination. Continuity from prenatal care to institutional delivery creates a loyalty to healthcare services and is the most significant and

  6. Biogas in Burkina Faso. Influential factors of biogas projects in rural areas of Burkina Faso

    Energy Technology Data Exchange (ETDEWEB)

    Aschaber, Andreas

    2010-07-01

    Full text: Burkina Faso is among the poorest countries in the world. The energy situation in Burkina Faso is among the most critical issues which need to be addressed in the country. The electrical power grid is insufficient and only available in urban centers. Consequently wood and charcoal is used in order to meet the basic needs for heating, cooking, and lightning by the majority of the population. The resulting overuse of natural energy resources in Burkina Faso has been causing massive deforestation and desertification on the one hand and on the other hand scarcity in fuel wood availability. According to a recent feasibility study of the GTZ, biogas is thought to be one of the most sustainable solutions for developing energy self sufficiency in rural areas of Burkina Faso. Biogas is not a new concept in Burkina Faso, as the first biogas plants were already installed in the 70's. Recently a national biogas program and the activity of various NGOs lead to a rejuvenation of attempts to establish biogas in Burkina Faso. Although biogas has a long history in Burkina Faso, no significant breakthrough of this technology has happened so far. None of the biogas plants built during the last 40 years have been operational for a long time. This contribution presents a study aimed to analyze the partial success and failures of the attempts to install biogas plants so far. The study was conducted in May 2009 as part of a project for a model application of the technology in the frame of University cooperation between Austria (University of Innsbruck) and Burkina Faso (Universite Polytechnique du Bobo Dioulasso). During the field study four sites of existing biogas plants were visited, five interviews with experts conducted and two focus groups with potential users in a rural setting were conducted. The systemic approach, including technical as well as socioeconomic aspects, yielded a wealth of factors which can potentially influence the success of biogas projects in

  9. Problems and energy choices in Burkina Faso

    International Nuclear Information System (INIS)

    This document is about the evaluation of the energy sector in Burkina Faso. It reports about the main issues of energy: poverty of the households, the lack of fund to finance the sector, desertification...The main resources of energy are firewood, fuel and electricity. The energy needs of Burkina Faso are related to the cooking of food, with liquid fuels intended for the railway transport and fuels used in industry and for the production of electricity. With regard to the transport sector, there is currently no possibility of substitution for the fuel, except the use of ethanol diluted in the gasoline. At the industrial level, agro-industrial, bagasse and the other residues constitute right now the independent source of energy for the production of industrial heat as well as for that of electricity. For the public network of electricity supply, the production rests exclusively on diesel power stations. Regarding the immense needs for its populations in energy, Burkina has only very limited resources. The biomass used for domestic needs cannot continuously ensure the households with the necessary energy supply for food cooking. As for the agro-industrial residues, they cannot reduce the industrial consumption of fuels. There are also hydraulic resources whose conscientious exploitation could contribute to decrease the fuel consumption in terms of electricity. In sum, it would be necessary to improve the regulation as regards firewood supply, to promote the use of improved hearths with wood, to plan the fuel supplies and to assist the SONABEL in the electric production capacities reinforcement of its fuel-based power stations

  17. Multivariate characterization on morphological traits in Burkina Faso sheep

    International Nuclear Information System (INIS)

    A total of 6440 female sheep from Burkina Faso were scored for seven body measurements and four qualitative morphological traits. Sampling included the three main environmental areas and sheep breeds of Burkina Faso: the Sahel area (Burkina-Sahel sheep), the Sudan- Sahel area (Mossi sheep) and the Sudan area (Djallonke sheep). Canonical analyses showed that differences in body measurements between the Sudan and the Sudan-Sahel sheep were small even though most body traits showed higher average values in the Burkina-Sahel sheep: the shortest Mahalanobis distance was found between the Sudan and the Sudan-Sahel populations (1.54), whilst that between the Sudan and the Sahelian populations was the largest (7.88). Discriminant analysis showed that most Sudan (Djallonke) individuals (60.85%) were classified as Sudan-Sahel (Mossi) individuals whilst most Burkina-Sahel individuals were classified into their environmental area of sampling (89.5%). Correspondence analyses indicated that the Burkina-Sahel sheep population clustered together with dropping ears, black and brown colour patterns and presence of wattles, the Sudan sheep were closely associated with long hair and vertical and curled ears and that the Sudan-Sahel sheep did not have clear associations with qualitative phenotypic traits. At the morphological level, the Sudan-Sahel (Mossi) sheep population can be considered a geographical subpopulation belonging to the Djallonke breed, showing some particularities, namely larger body size, due to the particular environmental condition of the area in which it is managed and a continuous gene flow from Sahelian sheep, The information reported in this study will be the basis for the establishment of further characterization, conservation and selection strategies for Burkina Faso sheep.

  2. Burkina Faso Experience with Establishment and Maintenance of an SSAC

    International Nuclear Information System (INIS)

    Burkina Faso is a State with Small Quantity Protocol and its Additional Protocol (INFCIRC/618/Add.1) interred into force on the 17 of April 2003. Burkina Faso is involved in the Agency nuclear security activities through many multilateral and bilateral agreements; and obviously, Safeguards Agreements. The International Atomic Energy Agency (IAEA)'s statutes have been ratified by Burkina Faso in 1998. The country became IAEA membership since 14 September 1998 (number of accession: 128). The basic law relating to radiation protection and nuclear safety has been voted by the National Assembly on 26 April 2005. This law is the legal basis that allowed the creation of the National Regulatory Authority for Radiation protection and Nuclear safety (ARSN). The global aim is to regulate activities involving nuclear materials or radioactive sources, to control the traffic of such materials and to manage radioactive waste within the country. ARSN is the national regulatory body competent for the control of the better use of ionizing radiation sources. This authority received mandate to establish and maintain an SSAC in accordance with the IAEA guidance. For the ARSN to be effective in its responsibilities, all activities involving radiation exposure are subjected to regulatory control by a system of notification, authorization by registration or licensing and inspection. Two separated infrastructures are dealing with nuclear energy. The first one, called Autorite Nationale de Radioprotection et de Surete Nucleaire (ARSN) ) is acting as a regulator. The second one, Secretariat Technique a l'Energie Nucleaire (STEA) acts as a promoter. During the Santa Fe International Training Course, USA may 2008, we agreed the Burkina Faso SSAC to be implemented by ARSN. The STEA should be involved by sending officially reports and declarations (received from ARSN) to the IAEA, through the National Liaison Officer. In order to maintain the SSAC, physical inventories are conducted, regularly

    In West Africa, health system funding rarely involves cross-subsidization among population segments. In some countries, a few community-based or professional health insurance programs are present, but coverage is very low. The financial principles underlying universal health coverage (UHC) sustainability and solidarity are threefold: 1) anticipation of potential health risks; 2) risk sharing and; 3) socio-economic status solidarity. In Burkina Faso, where decision-makers are favorable to national health insurance, we measured endorsement of these principles and discerned which management configurations would achieve the greatest adherence. We used a sequential exploratory design. In a qualitative step (9 interviews, 12 focus groups), we adapted an instrument proposed by Goudge et al. (2012) to the local context and addressed desirability bias. Then, in a quantitative step (1255 respondents from the general population), we measured endorsement. Thematic analysis (qualitative) and logistic regressions (quantitative) were used. High levels of endorsement were found for each principle. Actual practices showed that anticipation and risk sharing were not only intentions. Preferences were given to solidarity between socio-economic status (SES) levels and progressivity. Although respondents seemed to prefer the national level for implementation, their current solidarity practices were mainly focused on close family. Thus, contribution levels should be set so that the entire family benefits from healthcare. Some critical conditions must be met to make UHC financial principles a reality through health insurance in Burkina Faso: trust, fair and mandatory contributions, and education. PMID:26803656

    Full Text Available This study analyzes public funding in the agricultural sector in Burkina Faso and assesses its impact on agricultural growth. Based on data collected from several sources (finance acts over the period 1983-2008, Automated Prediction Instrument (IPA, World Bank and National agricultural statistics over 26 years (from 1983 to 2008, the agricultural production has been modelled by using an error correction model and Cobb-Douglas function. The econometric analysis results show that public funding has a positive impact on agricultural production in the short term. A 9% growth rate of public funding over the period 2009-2015, causes an average agricultural production of 6.75% over the period. So, it is necessary for the State to increase funding in the agricultural sector to achieve a better growth of the domestic production and to meet the Millennium Development Goals regarding hunger reduction over the period 2009-2015.

    With the "green economy" being promoted as a path to sustainable development and food security within the African continent, the influx of agricultural land is proliferating at a rapid pace often replacing natural savannah forests. Where agriculture is primarily rainfed, the possible adverse impacts of agricultural land influx on rainfall occurrences in water-limited areas such as West Africa warrant attention. Using field observations complemented by model calculations in southeastern Burkina Faso, the main causes of a 10-30% suppressed daytime rainfall recorded over agricultural fields when referenced to natural savannah forests are examined. Measurements and model runs reveal that the crossing of the mixed layer height and lifting condensation levels, a necessary condition for cloud formation and subsequent rainfall occurrence, was 30% more frequent above the natural savannah forest. This increase in crossing statistics was primarily explained by increases in measured sensible heat flux above the savannah forest rather than differences in lifting condensation heights.

    This paper describes the status quo of the power sector in Burkina Faso, its limitations, and develops a new methodology that through spatial analysis processes with the aim to provide a possible pathway for universal electricity access. Following the SE4All initiative approach, it recommends the more extensive use of distributed renewable energy systems to increase access to electricity on an accelerated timeline. Less than 5% of the rural population in Burkina Faso have currently access to electricity and supply is lacking at many social structures such as schools and hospitals. Energy access achievements in Burkina Faso are still very modest. According to the latest SE4All Global Tracking Framework (2015), the access to electricity annual growth rate in Burkina Faso from 2010 to 2012 is 0%. The rural electrification strategy for Burkina Faso is scattered in several electricity sector development policies: there is a need of defining a concrete action plan. Planning and coordination between grid extension and the off-grid electrification programme is essential to reach a long-term sustainable energy model and prevent high avoidable infrastructure investments. This paper goes into details on the methodology and findings of the developed Geographic Information Systems tool. The aim of the dynamic planning tool is to provide support to the national government and development partners to define an alternative electrification plan. Burkina Faso proves to be paradigm case for the methodology as its national policy for electrification is still dominated by grid extension and the government subsidising fossil fuel electricity production. However, the results of our analysis suggest that the current grid extension is becoming inefficient and unsustainable in order to reach the national energy access targets. The results also suggest that Burkina Faso’s rural electrification strategy should be driven local renewable resources to power distributed mini-grids. We find that

    Full Text Available AbstractThis paper examines entry into consensual unions versus marriages in BurkinaFaso, a topic that has received little attention to date in sub-Saharan Africa.Changes in marriage behaviors may entail or reflect profound changes in familyorganization, gender relations and fertility and, to the extent that consensualunions are relatively transitory and lead to more sexual partners, they may beassociated with greater sexual risks including HIV. The determinants of newunions being consensual are estimated from national family-life type survey datathat provide information on the timing of different types of marriages and thestart of cohabitation. While consensual unions are not new to the country, theyappear to be changing in nature and have been growing more common overtime especially in urban areas. They are also more popular among men andwomen with greater schooling or who began cohabiting while living outside thecountry, and for women who have previously lived in union.RésuméCet article compare les entrées en unions libres avec et les mariages au BurkinaFaso, un sujet ayant reçu peu d'attention en Afrique sub-saharienne jusqu'àprésent. Les changements de comportements reliés au mariage peuventimpliquer ou refléter de profondes modifications dans l'organisation desfamilles, dans les relations entre les sexes et dans la fécondité. Si les unionslibres sont en général plus transitoires que le mariage et entraînent un plusgrand nombre de partenaires sexuels, elles peuvent être associées à une haussede pratiques sexuelles à risque pouvant mener aux infections du VIH.

  13. Electricity consumption and economic growth in Burkina Faso: A cointegration analysis

    International Nuclear Information System (INIS)

    This study empirically establishes the direction of causality between electricity consumption and economic growth in Burkina Faso for the period 1968-2003. The bounds test yields evidence of cointegration between electricity consumption, GDP, and capital formation when electricity consumption and GDP are used as dependent variable. Causality results indicate that there is no significant causal relationship between electricity consumption and investment. Estimates, however, detect in the long-run a bidirectional causal relationship between electricity use and real GDP. There is also evidence of a positive feedback causal relationship between GDP and capital formation. Burkina Faso is therefore an energy dependent country. It is also a country in which electricity consumption is growing with the level of income. All of this shows that electricity is a significant factor in socio-economic development in Burkina Faso; as such, energy policy must be implemented to ensure that electricity generates fewer potential negative impacts.

  14. Updating the Northern Tsetse Limit in Burkina Faso (1949–2009: Impact of Global Change

    Full Text Available The northern distribution limit of tsetse flies was updated in Burkina Faso and compared to previous limits to revise the existing map of these vectors of African trypanosomiases dating from several decades ago. From 1949 to 2009, a 25- to 150-km shift has appeared toward the south. Tsetse are now discontinuously distributed in Burkina Faso with a western and an eastern tsetse belt. This range shift can be explained by a combination of decreased rainfall and increased human density. Within a context of international control, this study provides a better understanding of the factors influencing the distribution of tsetse flies.

    Post-stroke epilepsy (PSE) is defined as "recurrent seizures following stroke with confirmed diagnosis of epilepsy". Our objective was to describe the epidemiological, clinical and therapeutic PSE aspects at the Yalgado Ouedraogo Teaching Hospital, the main reference centre for neurological conditions in Burkina Faso. We conducted a retrospective study from January 2006 to December 2014. The data on thirty-two (32) cases of PSE was collected from a total of 1616 patients hospitalized for stroke, representing a rate of 1.98%. The patients' ages ranged from 25 to 77years old with a mean age of 58±10.39. There were 21 men and 11 women, with a gender ratio of 1.9. The time of occurrence of PSE ranged between 10 and 3600days (10years). The brain CT scan helped distinguish the different subtypes of stroke. Sixty-four percent (64%) of the cases experienced ischemic stroke and 36% of the cases cerebral hemorrhage. With regard to medical treatment, 23 patients received monotherapy, and 4 patients dual therapy. Exactly 96.87% of seizures were stabilized during the hospitalization period. PSE is a symptomatic type of epilepsy occurring during stroke sequelae. It is important not to lose sight of this before the occurrence of any focal or generalized seizure after a stroke.

  8. Household energy preferences for cooking in urban Ouagadougou, Burkina Faso

    International Nuclear Information System (INIS)

    An extensive survey on household expenditures in Ouagadougou, the capital of Burkina Faso, was used to analyze the factors determining urban household energy choices using a multinomial logit model. Wood-energy remains the preferred fuel of most urban households in the country; though rational, the choice is not sustainable as it portends a threat to the savanna woodlands and the economy. Many important policies have been adopted by public authorities to minimize household wood-energy consumption and to substitute it by alternative fuel. Despite the magnitude of all these policies, the depletion rate of the forest resource is increasing. A kind of inertia is thus observed for household preferences for cooking fuel. This model analyzes the sociological and economic variables of household energy preferences for cooking in Ouagadougou. The analyses show that the inertia of household cooking energy preferences are due to poverty factors such as low income, poor household access to electricity for primary and secondary energy, low house standard, household size, high frequency of cooking certain meals using woodfuel as cooking energy. The descriptive analyses show that the domestic demand for wood-energy is strongly related to household income. The firewood utilization rate decreases with increasing household income. In other words, this fuel appears as a 'transition good' for these households which aim for other sources of energy for cooking that are more adapted for urban consumption. This implies that a price subsidy policy for liquid petroleum gas (LPG) and its cook stoves could significantly decrease the utilization rate of wood-energy

  9. Health insurance and child mortality in rural Burkina Faso

    2015-04-01

    Full Text Available Background: Micro health insurance schemes have been implemented across developing countries as a means of facilitating access to modern medical care, with the ultimate aim of improving health. This effect, however, has not been explored sufficiently. Objective: We investigated the effect of enrolment into community-based health insurance on mortality in children under 5 years of age in a health and demographic surveillance system in Nouna, Burkina Faso. Design: We analysed the effect of health insurance enrolment on child mortality with a Cox regression model. We adjusted for variables that we found to be related to the enrolment in health insurance in a preceding analysis. Results: Based on the analysis of 33,500 children, the risk of mortality was 46% lower in children enrolled in health insurance as compared to the non-enrolled children (HR=0.54, 95% CI 0.43–0.68 after adjustment for possible confounders. We identified socioeconomic status, father's education, distance to the health facility, year of birth, and insurance status of the mother at time of birth as the major determinants of health insurance enrolment. Conclusions: The strong effect of health insurance enrolment on child mortality may be explained by increased utilisation of health services by enrolled children; however, other non-observed factors cannot be excluded. Because malaria is a main cause of death in the study area, early consultation of health services in case of infection could prevent many deaths. Concerning the magnitude of the effect, implementation of health insurance could be a major driving factor of reduction in child mortality in the developing world.

    Full Text Available Abstract Background There is concern about an increasing infiltration of markets by substandard and fake medications against life-threatening diseases in developing countries. This is particularly worrying with regard to the increasing resistance development of Plasmodium falciparum against affordable anti-malarial medications, which has led to a change to more expensive drugs in most endemic countries. Methods A representative sample of modern anti-malarial medications from licensed (public and private pharmacies, community health workers and illicit (market and street vendors, shops sources has been collected in the Nouna Health District in north-western Burkina Faso in 2006. All drugs were tested for their quality with the standard procedures of the German Pharma Health Fund-Minilab. Detected low standard drugs were re-tested with European Pharmacopoeia 2.9.1 standards for disintegration and ultraviolet-visible spectroscopy at the laboratory of the Heidelberg University for confirmation. Results Overall, 86 anti-malarial drug samples were collected, of which 77 samples have been included in the final analysis. The sample consisted of 39/77 (50% chloroquine, 10/77 (13% pyrimethamine-sulphadoxine, 9/77 (12% quinine, 6/77 (8% amodiaquine, 9/77 (12% artesunate, and 4/77 (5% artemether-lumefantrine. 32/77 (42% drug samples were found to be of poor quality, of which 28 samples failed the visual inspection, nine samples had substandard concentrations of the active ingredient, four samples showed poor disintegration, and one sample contained non of the stated active ingredient. The licensed and the illicit market contributed 5/47 (10.6% and 27/30 (90.0% samples of substandard drugs respectively. Conclusion These findings provide further evidence for the wide-spread existence of substandard anti-malarial medications in Africa and call for strengthening of the regulatory and quality control capacity of affected countries, particularly in view of the

    2010-01-01

    Full Text Available Striga hermonthica (Del. Benth. is an important constraint to cereal crop production in Burkina Faso, of which sorghum (Sorghum bicolor L. Moench is the most important component. Native Fusarium species to use as bio-control agents to S. hermonthica has been investigated. Fifty one Fusarium isolates obtained from diseased plants of S. hermonthica were evaluated for their pathogenicity against Striga under controlled environmental conditions. Of 51 Fusarium isolates, 14 were pathogenic to S. hermonthica but their virulence differed. These 14 isolates were evaluated for their effects on Striga seed germination in the laboratory and their ability to kill emerged Striga plants growing in greenhouse pots. Spores of Fusarium sp. isolates 150a-M, 125b-Za, 6-Fa, Fusarium equiseti isolates 5-Kou, 31-Kom, 32-Or, 13-Ba and Fusarium oxysporum isolate 34-Fo reduced Striga germination by 78 to 96% compared to the untreated control. The study showed that at the rate of 33 mg mL-1, metabolites of Fusarium sp. isolates 125b-Za, 6-Fa, F. equiseti 5-Kou and F. oxysporum 34-Fo prevented Striga seed germination. In addition to these four isolates, Fusarium sp. isolates 141b-O, 150a-M and F. equiseti isolate 32-Or were effective at 67 mg mL-1. Percentage of Striga mortality ranged from 17-37% between 14 and 28 days after inoculation with spores of F. oxysporum 34-Fo and F. equiseti 5-Kou. Striga dry biomass was reduced by 84 and 78% for the respective isolates compared to the untreated control with Striga. Sorghum yield was improved by 84 and 99% with Fusarium sp. 6-Fa and F. oxysporum 34-Fo, respectively, compared to the control without Striga. The use of Fusarium spores and metabolites against Striga offers different possibilities of bio-herbicides formulation that can be combined with other controls methods in the integrated Striga management. Further studies will be carried out under field conditions to assess the efficacy and safety of these Fusarium isolates to

    We estimate the effects of changes in cotton adoption on children's schooling and child labor in rural Burkina Faso. Cotton adoption increases household's income, leading to increased demand for schooling and reduced child labor. On the other hand, because children are productive on cotton farms, cotton adoption increases the opportunity cost of child time and the demand for child labor. Using time and spatial variation, we find evidence of a strong effect on school enrollment and child labor...

    Alice T C R Kiba Koumaré

    Full Text Available In Burkina Faso, the values that serve as clinical chemistry reference ranges are those provided by European manufacturers' insert sheets based on reference of the Western population. However, studies conducted so far in some African countries reported significant differences in normal laboratory ranges compared with those of the industrialized world. The aim of this study was to determine reference values of cholesterol fractions in apparently normal adults in Burkina Faso that could be used to better assess the risks related to cardiovascular diseases. Study population was 279 healthy subjects aged from 15 to 50 years including 139 men and 140 women recruited at the Regional Center of Blood Transfusion of Ouagadougou, capital city of Burkina Faso (West Africa. Exclusion criteria based on history and clinical examination were used for defining reference individuals. The dual-step precipitation of HDL cholesterol sub-fractions using dextran sulfate was performed according to the procedure described by Hirano. The medians were calculated and reference values were determined at 2.5th and 97.5th percentiles. The median and upper ranges for total cholesterol, LDL cholesterol, total HDL cholesterol and HDL2 cholesterol were observed to be higher in women in comparison to men (p <0.05. These reference ranges were similar to those derived from other African countries but lower than those recorded in France and in USA. This underscores the need for such comprehensible establishment of reference values for limited resources countries. Our study provides the first cholesterol sub-fractions (HDL2 and HDL3 reference ranges for interpretation of laboratory results for cardiovascular risk management in Burkina Faso.

    Full Text Available BACKGROUND: Paying for health care may exclude poor people. Burkina Faso adopted the DOTS strategy implementing "free care" for Tuberculosis (TB diagnosis and treatment. This should increase universal health coverage and help to overcome social and economic barriers to health access. METHODS: Straddling 2007 and 2008, in-depth interviews were conducted over a year among smear-positive pulmonary tuberculosis patients in six rural districts of Burkina Faso. Out-of-pocket expenses (direct costs associated with TB were collected according to the different stages of their healthcare pathway. RESULTS: Median direct cost associated with TB was US$101 (n = 229 (i.e. 2.8 months of household income. Respectively 72% of patients incurred direct costs during the pre-diagnosis stage (i.e. self-medication, travel, traditional healers' services, 95% during the diagnosis process (i.e. user fees, travel costs to various providers, extra sputum smears microscopy and chest radiology, 68% during the intensive treatment (i.e. medical and travel costs and 50% during the continuation treatment (i.e. medical and travel costs. For the diagnosis stage, median direct costs already amounted to 35% of overall direct costs. CONCLUSIONS: The patient care pathway analysis in rural Burkina Faso showed substantial direct costs and healthcare system delay within a "free care" policy for TB diagnosis and treatment. Whether in terms of redefining the free TB package or rationalizing the care pathway, serious efforts must be undertaken to make "free" health care more affordable for the patients. Locally relevant for TB, this case-study in Burkina Faso has a real potential to document how health programs' weaknesses can be identified and solved.

  18. Danida's support to the energy sector. Issues and contradictions with particular reference to Burkina Faso

    International Nuclear Information System (INIS)

    Danida support to energy sector in Burkina Faso was limited, until 1995, to the electricity sub-sector which has directly benefited less than 5% of the Burkinabe population. Danida made no attempt to develop renewable and local energy resources during the period 1979-1995 although 92% of primary energy supply and 98% of household energy use is met by wood fuels. During 1996 Danida's energy sector programme did, however, include support to strengthen energy policy and planning in Burkina Faso. This will address both wood fuel production systems and the development of new and alternative sources of energy. Danida is currently investigating potential co-financing of a regional traditional energy sector programme with the World Bank and the Netherlands Development Cooperation. A pilot natural forest management project will be initiated in 1997 in the Central-West and Northern Regions of Burkina Faso. A Danida-funded Projet de Developpement Rural dans le Boulgou, initiated in 1996, also includes support to the development and management of natural forest resources. (au)

    Full Text Available Abstract Background Introgression of Sahel livestock genes southwards in West Africa may be favoured by human activity and the increase of the duration of the dry seasons since the 1970’s. The aim of this study is to assess the gene flow patterns in Burkina Faso goat and to ascertain the most likely factors influencing geographic patterns of genetic variation in the Burkina Faso goat population. Results A total of 520 goat were sampled in 23 different locations of Burkina Faso and genotyped for a set of 19 microsatellites. Data deposited in the Dryad repository: http://dx.doi.org/10.5061/dryad.41h46j37. Although overall differentiation is poor (FST = 0.067 ± 0.003, the goat population of Burkina Faso is far from being homogeneous. Barrier analysis pointed out the existence of: a genetic discontinuities in the Central and Southeast Burkina Faso; and b genetic differences within the goat sampled in the Sahel or the Sudan areas of Burkina Faso. Principal component analysis and admixture proportion scores were computed for each population sampled and used to construct interpolation maps. Furthermore, Population Graph analysis revealed that the Sahel and the Sudan environmental areas of Burkina Faso were connected through a significant number of extended edges, which would be consistent with the hypothesis of long-distance dispersal. Genetic variation of Burkina Faso goat followed a geographic-related pattern. This pattern of variation is likely to be related to the presence of vectors of African animal trypanosomosis. Partial Mantel test identified the present Northern limit of trypanosome vectors as the most significant landscape boundary influencing the genetic variability of Burkina Faso goat (p = 0.008. The contribution of Sahel goat genes to the goat populations in the Northern and Eastern parts of the Sudan-Sahel area of Burkina Faso was substantial. The presence of perennial streams explains the existence of trypanosome vectors. The South

    Studies on host factors, particularly the APOBEC3G gene, have previously found an association with AIDS progression in some populations and against some HIV-1 strains but not others. Our study had two main objectives: firstly, to screen a population from Burkina Faso for three variants of APOBEC3G previously described, and secondly to analyze the effect of these three variants and their haplotypes on HIV-1 infection with Circulating Recombinant Forms (CRFs) present in Burkina Faso. This case control study involved 708 seropositive and seronegative individuals. Genotyping was done by the TaqMan allelic discrimination method. Minor allele frequencies of rs6001417 (pratio analysis of genotypes and alleles of the different APOBEC3G variants showed that there is a strong association between the minor genetic variants, genotype of the three SNPs, and HIV-1 status. Haplotype analysis demonstrated that rs6001417, rs8177832, and rs35228531 are in linkage disequilibrium.

    Full Text Available Abstract Background In sub-Saharan Africa, women must overcome numerous barriers when they need modern healthcare. Respect of gender norms within the household and the community may still influence women's ability to obtain care. A lack of gender-sensitive instruments for measuring women's ability to overcome barriers compromises attempts to adequately quantify the burden and risk of exclusion they face when seeking modern healthcare. The aim of this study was to create and validate a synthetic measure of women's access to healthcare from a publicly available and possibly internationally comparable population-based survey. Method Seven questionnaire items from the Burkina Faso 2003 DHS were combined to create the index. Cronbach's alpha coefficient was used to test the reliability of the index. Exploratory factor analyses (EFA and confirmatory factor analyses (CFA were applied to evaluate the factorial structure and construct validity of the index while taking into account the hierarchical structure of the data. Results The index has a Cronbach's alpha of 0.75, suggesting adequate reliability. In EFA, three correlated factors fitted the data best. In CFA, the construct of perceived ability to overcome barriers to healthcare seeking emerged as a second-order latent variable with three domains: socioeconomic barriers, geographical barriers and psychosocial barriers. Model fit indices support the index's global validity for women of reproductive age in Burkina Faso. Evidence for construct validity comes from the finding that women's index scores increase with household living standard. Conclusion The DHS items can be combined into a reliable and valid, gender-sensitive index quantifying reproductive-age women's perceived ability to overcome barriers to healthcare seeking in Burkina Faso. The index complies conceptually with the sector-cross-cutting capability approach and enables measuring directly the perceived access to healthcare. Therefore it

    Full Text Available Malaria control programs are being jeopardized by the spread of insecticide resistance in mosquito vector populations. The situation in Burkina Faso is emblematic with Anopheles gambiae populations showing high levels of resistance to most available compounds. Although the frequency of insecticide target-site mutations including knockdown resistance (kdr and insensitive acetylcholinesterase (Ace-1(R alleles has been regularly monitored in the area, it is not known whether detoxifying enzymes contribute to the diversity of resistance phenotypes observed in the field. Here, we propose an update on the phenotypic diversity of insecticide resistance in An. gambiae populations sampled from 10 sites in Burkina Faso in 2010. Susceptibility to deltamethrin, permethrin, DDT, bendiocarb and fenithrotion was assessed. Test specimens (N = 30 per locality were identified to species and molecular form and their genotype at the kdr and Ace-1 loci was determined. Detoxifying enzymes activities including non-specific esterases (NSEs, oxydases (cytochrome P450 and Glutathione S-Transferases (GSTs were measured on single mosquitoes (N = 50 from each test locality and compared with the An. gambiae Kisumu susceptible reference strain. In all sites, mosquitoes demonstrated multiple resistance phenotypes, showing reduced mortality to several insecticidal compounds at the same time, although with considerable site-to-site variation. Both the kdr 1014L and Ace-1(R 119S resistant alleles were detected in the M and the S forms of An. gambiae, and were found together in specimens of the S form. Variation in detoxifying enzyme activities was observed within and between vector populations. Elevated levels of NSEs and GSTs were widespread, suggesting multiple resistance mechanisms segregate within An. gambiae populations from this country. By documenting the extent and diversity of insecticide resistance phenotypes and the putative combination of their underlying

    2015-07-01

    Full Text Available This commentary traces recent regime change and political transition in Burkina Faso. After mass demonstrations Blaise Compaoré was forced to resign his presidency on 31 October 2014. His resignation was preceded by his attempt to change the constitution to allow him to stand for a fifth consecutive term in office. It is argued in this briefing that the way Compaoré’s rule ended should have come as no surprise because it was typical of both Burkina Faso’s political history since decolonisation and also the army’s historical role in the country’s presidential turnover. It was also typical of the current wave of mass protest struggles taking place in other African countries.

    2012-07-01

    Full Text Available Abstract Background and methods A longitudinal Anopheles gambiae s.l. insecticide-resistance monitoring programme was established in four sentinel sites in Burkina Faso. For three years, between 2008 and 2010, WHO diagnostic dose assays were used to measure the prevalence of resistance to all the major classes of insecticides at the beginning and end of the malaria transmission season. Species identification and genotyping for target site mutations was also performed and the sporozoite rate in adults determined. Results At the onset of the study, resistance to DDT and pyrethroids was already prevalent in An. gambiae s.l. from the south-west of the country but mosquitoes from the two sites in central Burkina Faso were largely susceptible. Within three years, DDT and permethrin resistance was established in all four sites. Carbamate and organophosphate resistance remains relatively rare and largely confined to the south-western areas although a small number of bendiocarb survivors were found in all sites by the final round of monitoring. The ace-1R target site resistance allele was present in all localities and its frequency exceeded 20% in 2010 in two of the sites. The frequency of the 1014F kdr mutation increased throughout the three years and by 2010, the frequency of 1014F in all sites combined was 0.02 in Anopheles arabiensis, 0.56 in An. gambiae M form and 0.96 in An. gambiae S form. This frequency did not differ significantly between the sites. The 1014S kdr allele was only found in An. arabiensis but its frequency increased significantly throughout the study (P = 0.0003 and in 2010 the 1014S allele frequency was 0.08 in An. arabiensis. Maximum sporozoite rates (12% were observed in Soumousso in 2009 and the difference between sites is significant for each year. Conclusion Pyrethroid and DDT resistance is now established in An. gambiae s.l. throughout Burkina Faso. Results from diagnostic dose assays are highly variable within and

    Despite health reform and increasing public investment in the health sector, utilization of curative health services, immunization coverage and patient satisfaction with the public health care system are steadily decreasing in Burkina Faso. It seems that the health care system itself is "ill". This paper examines the major symptoms associated with this illness. The central thesis suggests that any further improvement of health care performance in Burkina Faso will be subject to profound central reform in the area of human resources and financial management of the sector. Such a broad reform package cannot be achieved through the current project approach, but a sector-wide approach (SWAp) does not seem to be realistic at the present time. Policy discussions at a level higher than the Ministry of Health could be beneficial for achieving better donor coordination and increasing the commitment of the Ministry of Health to a sector-wide approach. Health sector reform issues and priorities and the role of international cooperation are reviewed and discussed. PMID:11238434

    Many studies, using information integration theory, have been devoted to the prediction of performance on the basis of ability and motivation information. However, it appears that only two societies. American and East Indian, have been examined with regard to their prevalent performance prediction model. Participants in this study were school children in Burkina Faso, West Africa. Considerable differences between individuals were expected because, as a consequence of colonization, Burkina Faso has been torn between two different value systems: a collectivistic system, with traditional tribal Burkinabè values, and an individualistic system, with occidental values. The study's most notable finding was the coexistence of these two value systems within the same society. The predominant logic of Western societies, that increased motivation will result in increased rewards when initial ability is high, was utilized by 42% of the children; in contrast, 38% of the children applied the dominant logic expressed by East Indian researchers, who have found that regardless of the level of ability, any amount of motivation will result in an identical improvement in performance.

    Full Text Available Abstract Background In the absence of large scale, organized vector control programmes, individual protective measures against mosquitoes are essential for reducing the transmission of diseases like malaria. Knowledge of the types and effectiveness of mosquito control methods used by households can aid in the development and promotion of preventive measures. Methods A matched, population-based case control study was carried out in the semi-urban region of Nouna, Burkina Faso. Surveys and mosquito captures were conducted for each participating household. Data were analysed using conditional logistic regression and Pearson's product-moment correlations. Results In Nouna, Burkina Faso, the main types of reported mosquito control measures used included sleeping under bed nets (insecticide-treated and untreated and burning mosquito coils. Most of the study households kept animals within the compound or house at night. Insecticide house sprays, donkeys, rabbits and pigs were significantly associated with a reduced risk of malaria only in univariate analyses. Conclusion Given the conflicting results of the effects of zooprophylaxis from previous studies, other community-based preventive measures, such as bed nets, coils and insecticide house-spraying, may be of more benefit.

    Objective:To evaluate the prevalence of toxoplasmosis and rubella among pregnant women at Ouagadougou in Burkina Faso. Methods: All patient sera were tested for rubella and toxoplasmosis anti-IgG using commercial ELISA kits (PlateliaTM Rubella IgG and Platelia™Toxo IgG). The presence of anti-rubella and anti-toxoplasmosis IgM in serum samples was tested using commercial ELISA kits Platelia Rubella IgM and Platelia Toxo IgM. Results:Among all the pregnant women tested for toxoplasmosis and rubella, their prevalence were 20.3%and 77.0%, respectively. Pregnant women in the age group of 18-25 years showed the highest frequency of anti-toxoplasmosis (34.5%) and anti-rubella IgG (84.6%). The prevalence of anti-toxoplasma and anti-rubella IgG decreased between 2006 and 2008 from 32.7%to 12.1%and 84.6%to 65.0%, respectively. There was no significant association between age and the mean titer of anti-toxoplasmosis IgG among pregnant women. Conclusions: The diagnosis of toxoplasmosis and rubella is necessary in pregnant women in Burkina Faso because of the low immunization coverage rate of rubella and the high level of exposure to these two infections which can be harmful to the newborn if contracted by women before the third trimester of pregnancy.

    Sorghum malt and dolo quality evaluation criteria and parameters affecting quality were surveyed in six cities in Burkina Faso through questionnaires addressed to malt processors, dolo processors, retailers, and consumers. The major quality criteria for malt quality assessment were perceived to be taste and presence/absence of roots in the malt. Taste, alcohol content, and wort sufficiently cooked were perceived as major criteria for the dolo quality assessment. The major parameters affecting malt quality were perceived to be malt production period, proportions of grain and the amount of water entering malting, presence of pesticide residues in the malting grains, and age of grain. Processing method, yeast source, proportions of the components (crushed grain, water, mucilage, yeast) entering dolo production, malt quality, wort temperature at time of inoculation, amount of energy available for cooking, wort and sediment boiling time, quality of mucilage, malt with non-sweet taste, presence/absence of roots in the malt, and ease of filtering crushed malt were perceived as major parameters affecting the dolo quality. These results will be used in the improvement of the dolo supply chain in Burkina Faso by providing more reliable information for training programs for efficient dolo brewing processes, development of best cropping practices to improve grain quality, and providing better selection criteria for sorghum breeding programs.

    International Nuclear Information System (INIS)

    In the central region of the Burkina Faso, small holders like to use veterinary traditional practice to treat small ruminant gastro-intestinal parasitism. In this part of country, Daniellia oliveri plant is usually used against this disease. Aqueous decoction obtained from the stem barc of Daniellia oliveri was screened to determine his phytochemical composition and in vitro anthelminthic activity agains Haemonchus contortus adult worms. Results showed that the decoction lyophilized obtained is giving to small ruminant (25 kg) at the rate of 242.5 mg per body weight. In vitro anthelminthic revealed that Daniellia oliveri extract has significant effect (P < 0.05) on mortality or the paralysis of the adult worms of Haemonchus contortus compared to the control group. In fact, use of Daniellia oliveri leaves by pastoralist smallholders in traditional therapy against the gastro-intestinal small ruminant parasites is justified in the central region of the Burkina Faso. Therefore, the survey suggests to achieve other studies (phytochemical and toxicity) on Anogeissus leiocarpus leaves studied in order to develop a further drug antiparasitic subsequently

    Traditional Veterinary practice is current by pastoralist and small holders to treat small ruminant gastro-intestinal parasitism in the central region of the Burkina Faso. To treat these digestive pathologies, Anogeissus leiocarpus is usually used. Ethno-veterinary surveys have been achieved to understand the traditional use of Anogeissus leiocarpus and in vitro test has been carried out to value anthelminthic activity on the adult worms of Haemonchus contortus. Results showed that the plant part used are leaves and by oral way after decoction to obtain aqueous extract which is giving to small ruminant (25 kg) at the rate of 160 mg per body weight. In vitro anthelminthic activity test of aqueous extract of leaves revealed a significant effect (P < 0,05) on mortality or the paralysis of the adult worms of Haemonchus contortus compared to the control group (PBS). In fact, use of Anogeissus leiocarpus leaves by pastoralist and small holders in traditional therapy against the gastro-intestinal small ruminant parasites is justified in the central region of the Burkina Faso. Therefore, the survey suggests to achieve other pharmacologies and parasitologies studies on Anogeissus leiocarpus leaves in order to develop a further drug antiparasitic subsequently

  9. Study of the biomass potential that can be used for producing biogas in Burkina Faso

    International Nuclear Information System (INIS)

    The introduction of biogas to Burkina Faso was done in 1976 through program of research and development. Agricultural and Animal waste is the principal substrates and the produced gas is useful principally to satisfy the domestic energy needs. The technological outputs go from 200 has 300 liters per m3 of tank whereas the biological outputs are of 100 has 300 liters per kilogram of dry matter. The cost of the installations vary from 12000 to 100000 Fcfa per m3 of tank according to the type of digester. In August 1998, only the installation of biogas of the School of Water and Drill of Dinderesso (Bobo-Dioulasso) produced biogas. According to the estimates, Burkina Faso respectively has an annual average potential of production theoretical and accessible about 4694 million and 2790 million m3 of biogas coming by order from importance from livestock wastes, farming, human and urban. By taking a coefficient of 60% to take account of the imperfections of technology and implementation, 1674 million m3 of biogas (accessible) could have been produced from the biomass over the period 1990-1996. For the same period, this quantity of biogas could have generated annually 2000 to 2344 GWh of electricity (cogeneration) against 218 GWh for the SONABEL

    Burkina Faso is part of the Sahel-Sudan climatic zone south of the Sahara Desert. The rainfall of the region is characterized by extreme seasonal and annual temporal and spatial variability. Soils are generally of low fertility. The major livelihood activity in Burkina Faso, one of the lowest ranked countries in the world in the Human Development Index where 80 percent of the population rely on subsistence farming, is rainfed cultivation of cereal crops. Cotton is the dominant export crop and is mostly grown in the southwest. Livestock management is an important complement to farm activities, especially in the Sahelian zone. There are several major rivers flowing through the region and many ephemeral streams. Surface water resources are becoming more important to Burkina Faso as it tries to improve food security and water supplies, and increase energy production. One of the major opportunities to improve livelihoods in the region has been improvements in seasonal rainfall forecasting based upon global sea surface temperatures. In the past decade, the generation and use of forecasts in Burkina Faso has evolved from the nation just receiving forecasts almost as an after thought from USA and European meteorological services to the Burkina Faso Meteorological Services generating their own forecasts with support from these services. There is now also more focused international research on improving the forecasts for this region. The use of stochastic decision support tools (DST) that combine the seasonal forecasts with hydrologic and crop models, land conditions, and information on farmer and policy maker goals could improve both rainfed and irrigated agricultural systems. Their implementation requires overcoming many technical and socio-economic challenges. Examples include forecasting the start and end of rains, dissemination and explanation of forecasts, streamflow forecasting in data scarce regions, possible different incentives for subsistence and cash crop farmers

    Labor migration from Burkina Faso did not end when direct recruitment of workers by planters from the Ivory Coast was terminated at independence in 1960. Methodological problems and differences in the objectives of the 1975 and 1985 censuses and the 1960-61 sample survey have limited the usefulness of existing data on migration. Migrants from Burkina Faso have always been unskilled workers in search of wage employment. The migrant population in 1960-61 was estimated at 152,442, of whom 90% were males primarily under 40 years old. The proportion of women and children increased from 8.2% in 1961 to 12.8% in 1973. Between the 1975 and 1985 censuses, there were few significant changes in the dominant characteristics of migrants. 80% of the 808,000 residents living abroad according to official sources were male and 80% were aged 15-40 years. 53% of migrants according to a 1975 study were under 20 years old at the 1st departure, and most were single. At the national level, labor migration is viewed as a necessary evil that should continue as long as possible in the absence of employment opportunities at home. After independence in 1960, 56.6% of migrants from Burkina Faso went to the Ivory Coast, 31.3% to Ghana, and 3.9% to Mali. In 1975 and 1985 respectively, 74.4% and 91.2% went to the Ivory Coast and 11.8% and 8.8% to Ghana. The demographic consequences of migration in Burkina Faso include a lowering of the natural increase rate and a reduction of the economically active population amounting to about 16% between 1975-85. The disproportionate departure of men has left an increasing number of women in charge of agricultural operations. A strong current of return migration has also developed, including many children under 15. It was estimated in 1990 that half of migrants to the Ivory Coast receive professional training, with the other half exposed to new agricultural techniques and methods of organizing work. 87% of returning male migrants in 1985 went back to their

Our aim was to investigate the key determinants of induced abortion in a sample of women who sought postabortion care. Materials and methods: A cross-sectional household survey was carried out from February to September 2012 in Ouagadougou, Burkina Faso. Data of 37 women who had had an induced abortion and 267 women who had had a spontaneous abortion were prospectively collected on sociodemographic characteristics, pregnancy and birth history, abortion experience, including previous abortion experience, and selected clinical information, including the type of abortion. A two-step regression analysis consisting of a univariate and a multivariate logistic regression was run on Stata version 11.2 in order to identify the key determinants of induced abortion. Results: The findings indicated that 12% of all abortions were certainly induced. Three key factors were significantly and positively associated with the probability of having an induced abortion: whether the woman reported that her pregnancy was unwanted (odds ratio [OR] 10.45, 95% confidence interval [CI] 3.59–30.41; whether the woman reported was living in a household headed by her parents (OR 6.83, 95% CI 2.42–19.24; and if the woman reported was divorced or widowed (OR 3.47, 95

    Full Text Available The various kinds of information released in the press and other media are cultural products that partake in the shaping of citizens' opinions and minds. Radio and television in particular present their audiences in Burkina Faso with various life-styles through diverse entertainment programmes which have grown popular among the urban population. These are fertile fields for cultural imperialism in the country. In the on-going process of internationalization of culture facilitated by the new communication technology, the cultural identity of Africans is increasingly threatened. This phenomenon is the result of adverse political and economic conditions with significant cultural consequences. In the long run, these cultural consequences will lead to the marginalization of Africa on the international scene and its increased dependence on the western powers.

    Full Text Available The influence of MgO on mechanical and microstructural properties of raw clay material from Burkina Faso was investigated by means of X-ray diffraction, scanning electron microscopy, infrared spectroscopy, differential thermal analysis and numerical simulation. The mineralogical composition was modified with the formation of new crystalline phases such as mullite, spinel – Mg, enstatite and forsterite. During the sintering and with add of MgO, the mullite quantity decrease contrary to forsterite and affect the different properties of sintered products. The mechanical properties were improved with MgO amount around 2 – 5 wt%. For magnesia amount higher than 5 wt%, the magnesia is not entirely consumed and is originated to the formation of pores in the manufactured products which are detrimental to the mechanical properties.

    Enteric viruses are a major cause of diarrhea in children, especially those under five years old. Identifying the viral agents is critical to the development of effective preventive measures. This study aimed to determine the prevalence and genetic diversity of common enteric viruses in children under five years old in Burkina Faso. Stool samples from children with (n = 263) and without (n = 50) diarrhea disorders were collected in Ouagadougou, Burkina Faso from November 2011 to September 2012. Rotavirus, norovirus, sapovirus, astrovirus, adenovirus and Aichivirus A were detected using real-time or end-point (RT-)PCR. Rotavirus strains were G and P genotyped by multiplex RT-PCR and other viral strains were characterized by sequencing of viral subgenomic segements. At least one viral agent was detected in 85.6% and 72% of the symptomatic and asymptomatic patients, respectively. Rotavirus (63.5%), adenovirus (31.2%) and genogroup II norovirus (18.2%) were the most prevalent viruses in symptomatic patients, but only rotavirus and genogroup II norovirus were significantly associated with diarrhea (OR: 7.9, 95%CI: 3.7-17; OR: 3.5, 95%CI: 1-11.7, respectively). Sapovirus (10.3%), astrovirus (4.9%), genogroup I norovirus (2.7%) and Aichivirus A (0.8%) were less prevalent. The predominant genotype of rotavirus was G9P[8] (36.5%), and the predominant norovirus strain was GII.4 variant 2012 (71.4%). Among sapovirus, the genogroup II (87.5%) predominated. Astrovirus type 1 (41.7%) was the most frequent astrovirus identified. Aichivirus A belonged to the three genotypes (A, B and C). Enteric adenoviruses type 40 and 41 were identified in 10.2% and 5.1% respectively. Several cases of co-infections were detected. The results highlight the high prevalence and the high diversity of enteric viruses in Burkinabe children. PMID:27092779

    Riparian forests are classified as endangered ecosystems in general, particularly in sahelian countries like Burkina Faso because of human-induced alterations and civil engineering works. The modification of this important habitat is continuing, with little attention being paid to the ecological or human consequences of these changes. The objective of this study is to describe the variation of woody species diversity and dynamic in riparian forests on different type of watercourse banks along phytogeographical gradient in Burkina Faso. All woody species were systematically measured in 90 sample plots with sides of 50 m × 20 m.Density, dominance, frequency and species and family importance values were computed to characterize the species composition. Different diversity indices were calculated to examine the heterogeneity of riparian forests. A total of 196 species representing 139 genera and 51 families were recorded in the overall riparian forests. The species richness of individuals with dbh ≥ 5cm increased significantly from the North to the South along the phytogeographical gradient and varied significantly between the different types of riparian forests. Similarity in tree species composition between riparian forests was low, which indicates high beta diversity and reflects differences in habitat conditions and topography.The structural characteristics varied significantly along the phytogeographical gradient and between the different types of riparian forests.The diameter class distribution of trees in all riparian forests showed a reverse “J” shaped curve except riparian forest of stream indicating vegetation dominated by juvenile individuals. Considering the ecological importance of riparian forest, there is a need to delineate and classify them along watercourses throughout the country.

  6. Reducing the medical cost of deliveries in Burkina Faso is good for everyone, including the poor.

    Full Text Available Since 2007, Burkina Faso has subsidized 80% of the costs of child birth. Women are required to pay 20% (900 F CFA = 1.4 Euros, except for the indigent, who are supposed to be exempted. The objective of the policy is to increase service utilization and reduce costs for households. We analyze the efficacy of the policy and the distribution of its benefits.The study was carried out in Ouargaye district. The analysis was based on two distinct cross-sectional household surveys, conducted before (2006; n= 1170 and after (2010; n = 905 the policy, of all women who had had a vaginal delivery in a public health centre.Medical expenses for delivery decreased from a median of 4,060 F CFA in 2006 to 900 F CFA in 2010 (p<0.001. There was pronounced contraction in the distribution of expenses and a reduction in interquartile range. Total expenses for delivery went from a median of 7,366 F CFA in 2006 to 4,750 F CFA in 2010 (p = 0.001. There was no exacerbation of the initial inequalities of the share in consumption after the policy. The distribution of benefits for medical expenses showed a progressive evolution. The greatest reduction in risk of excessive expenses was seen in women in the bottom quintile living less than 5 km from the health centres. Only 10% of those in the poorest quintile were exempted. The subsidy policy was more effective in Burkina Faso than in other African countries. All categories of the population benefited from this policy, including the poorest. Yet despite the subsidy, women still carry a significant cost burden; half of them pay more than they should, and few indigents are fully exempted. Efforts must still be made to reach the indigent and to reduce geographic barriers for all women.

  7. Efficiency of primary care in rural Burkina Faso. A two-stage DEA analysis

    Science.gov (United States)

    2011-01-01

    Background Providing health care services in Africa is hampered by severe scarcity of personnel, medical supplies and financial funds. Consequently, managers of health care institutions are called to measure and improve the efficiency of their facilities in order to provide the best possible services with their resources. However, very little is known about the efficiency of health care facilities in Africa and instruments of performance measurement are hardly applied in this context. Objective This study determines the relative efficiency of primary care facilities in Nouna, a rural health district in Burkina Faso. Furthermore, it analyses the factors influencing the efficiency of these institutions. Methodology We apply a two-stage Data Envelopment Analysis (DEA) based on data from a comprehensive provider and household information system. In the first stage, the relative efficiency of each institution is calculated by a traditional DEA model. In the second stage, we identify the reasons for being inefficient by regression technique. Results The DEA projections suggest that inefficiency is mainly a result of poor utilization of health care facilities as they were either too big or the demand was too low. Regression results showed that distance is an important factor influencing the efficiency of a health care institution Conclusions Compared to the findings of existing one-stage DEA analyses of health facilities in Africa, the share of relatively efficient units is slightly higher. The difference might be explained by a rather homogenous structure of the primary care facilities in the Burkina Faso sample. The study also indicates that improving the accessibility of primary care facilities will have a major impact on the efficiency of these institutions. Thus, health decision-makers are called to overcome the demand-side barriers in accessing health care. PMID:22828358

    Full Text Available Cette étude évalue l’impact des changements climatiques sur les revenus agricoles des agriculteurs au Burkina Faso, en utilisant l’approche ricardienne. Cette méthode permet de modéliser les revenus agricoles en fonction des variables climatiques, édaphiques, hydrologiques et socio-économiques. Plusieurs modèles économétriques ont été testés sur la base des données primaires de la campagne agricole 2002-2003. Ces modèles ont permis d’établir d’une part la relation qui existe entre le revenu agricole et les variables climatiques (température et précipitation et d’autre part, d’analyser la sensibilité des revenus agricoles par rapport à ces variables climatiques. Des simulations ont été faites sur la base des prévisions du groupe d’experts intergouvernemental sur l’évolution du climat (GIEC. Les résultats de l’étude ont montré que la relation entre le revenu et le climat est non linéaire. L’impact marginal de la température sur le revenu agricole est de -19,9 dollars US par hectare tandis que celui de la précipitation est de +2,7 dollars US par hectare. L’analyse des élasticités montre que l’agriculture est très sensible à la précipitation au Burkina. L’augmentation des précipitations de 1% entraine une hausse des revenus agricoles de 14,7%. Cependant, une augmentation des températures de 1% entraine une baisse des revenus agricoles de 3,6%. Les analyses de sensibilité ont montré que les paysans perdront 93% de leurs revenus suite à une augmentation de la température de 5°C. Ils perdront tout leur revenu suite à une diminution des précipitations de 14% (ceteris paribus. Du fait des conditions climatiques déjà difficiles, les scenarii de diminution des précipitations ou/et d’augmentation des températures sont très dommageables à l’agriculture au Burkina. Par ailleurs, l’étude a montré que la pratique de l’irrigation et l’accès à la vulgarisation ont un effet

    Full Text Available A Mobile Laboratory was developed for use primarily during the epidemic meningitis season in Burkina Faso. This report describes the Mobile Laboratory characteristics, its use to date, problems encountered and their resolution, and future directions. During 2004, the mobile laboratory intervention in three remote Burkina Faso districts experiencing meningitis epidemics led to more specific case management and led directly to vaccination of one district. However, in a second district, the intervention occurred too late to allow vaccination. During 2006, the Mobile Laboratory was used to conduct an emergency carriage study that for the first time occurred during the peak of a meningococcal serogroup A epidemic. This information is critical for the design of meningococcal conjugate vaccine schedules and vaccine approaches. During 2004-6, technicians in 11 district laboratories received training by Mobile Laboratory staff. Numerous problems with the initial prototype laboratory were identified, namely that the solar power cells could not provide enough energy to the refrigerator and incubator to maintain appropriate temperatures and having a single integrated unit required use of a separate vehicle for specimen transport. A second laboratory was developed during 2005-6 that used a generator or local energy source for power and that had a laboratory that could be detached from the vehicle. Currently the main limitation of the Mobile Laboratory is that it has not been integrated into routine Ministry of Health activities, limiting its use both during and between meningitis seasons.Un Laboratoire Mobile a été développé pour être utilisé essentiellement pendant la saison d’épidémie de méningite au Burkina Faso.

    Full Text Available Abstract Background Drug-resistant tuberculosis (DR-TB is considered a real threat to the achievement of TB control. Testing of mycobacterial culture and testing of drug susceptibility (DST capacity are limited in resource-poor countries, therefore inadequate treatment may occur, favouring resistance development. We evaluated the molecular assay GenoType® MTBDRplus (Hain Lifescience, Germany in order to detect DR-TB directly in clinical specimens as a means of providing a more accurate management of chronic TB patients in Burkina Faso, a country with a high TB-HIV co-infection prevalence. Methods Samples were collected in Burkina Faso where culture and DST are not currently available, and where chronic cases are therefore classified and treated based on clinical evaluation and sputum-smear microscopy results. One hundred and eight chronic TB patients (sputum smear-positive, after completing a re-treatment regimen for pulmonary TB under directly observed therapy were enrolled in the study from December 2006 to October 2008. Two early morning sputum samples were collected from each patient, immediately frozen, and shipped to Italy in dry ice. Samples were decontaminated, processed for smear microscopy and DNA extraction. Culture was attempted on MGIT960 (Becton Dickinson, Cockeysville, USA and decontaminated specimens were analyzed for the presence of mutations conferring resistance to rifampin and isoniazid by the molecular assay GenoType® MTBDRplus. Results We obtained a valid molecular test result in 60/61 smear-positive and 47/47 smear-negative patients.

    Desclaux, A

    1997-01-01

    The first cases of AIDS in Burkina Faso were reported in 1986. During the past ten years, there have been several types of research conducted in Burkina Faso in the field of social sciences, including KABP, focus groups, and ethnographic studies. This article reviews approximately 100 publications and presents the results most relevant to prevention. Although general knowledge of the disease, its transmission and means of protection has improved, part of the population remains poorly informed; erroneous ideas remain prevalent and certain concepts, for example asymptomatic infection, are ignored. Young women in rural areas have the poorest knowledge. Understanding the information is conditioned by underlying perceptions of blood and physiology, the "components of the person", pre-existent and sexually transmitted diseases, and modes of transmission. Research on sexuality has elucidated the age at which individuals become sexually active, and paramatrimonial practices. The prevalence of STD is high. STD are mostly treated by traditional practitioners or by automedication. Family planning is insufficiently developed. AIDS prevention should be integrated into wider considerations of reproductive health. The popular perception that "Others" are responsible for bringing AIDS into the country has often been reinforced by health messages. Consequently, people do not sufficiently consider themselves vulnerable to HIV infection. The populations that are most vulnerable, for various reasons that have been analysed, include young girls and women, married women, prostitutes, truck drivers, and young men from rural areas. The message "Fidelity or condom" has been widely used. However, it has hindered the generalisation of the use of condoms, because asking for a condom consequently implies distrust of the partner. The interpretation of fidelity is diverse, and many people who choose this means of prevention believe erroneously that they are protected. Studies of the social

The PROMISE-EBF trial, during which we promoted exclusive breastfeeding, gave us the opportunity to describe the epidemiology of PNM in Banfora Health District, South-West in Burkina Faso. Study objectives To measure the perinatal mortality rate (PNMR in the PROMISE-EBF cohort in Banfora Health District and to identify potential risk factors for perinatal death. Methods We used data collected prospectively during the PROMISE-EBF-trial to estimate the stillbirth rate (SBR and early neonatal mortality rate (ENMR. We used binomial regression with generalized estimating equations to identify potential risk factors for perinatal death. Results 895 pregnant women were enrolled for data collection in the EBF trial and followed-up to 7 days after birth. The PNMR, the SBR and the ENMR, were 79 per 1000 (95% CI: 59-99, 54 per 1000 (95% CI: 38-69 and 27 per 1000 (95% CI: 9-44, respectively. In a multivariable analysis, nulliparous women (RR = 2.90, 95% CI: 1.6-5.0, primiparae mothers (RR = 2.20, 95% CI: 1.2-3.9, twins (RR = 4.0, 95% CI: 2.3-6.9 and giving birth during the dry season (RR = 2.1 95% CI: 1.3-3.3 were factors associated with increased risk of perinatal death. There was no evidence that risk of perinatal death differed between deliveries at home and at a health centre Conclusion Our study observed the highest PNMR ever reported in Burkina. There is an urgent need for sustainable interventions to improve maternal and newborn health in the country.

    This study examines variations in the performance of partic-ipatory forest management programs among four forest management groups (FMGs) in southern Burkina Faso, and assesses the factors that influence their members’ perceptions of performance through a house-hold survey of 216 members. Variations in performance scores among the FMGs were analyzed through multivariate analysis of variance while multinomial regression analysis was used to identify factors that influ-ence their perception of the performance. The results reveal significant differences in performance scores among FMGs. Members of some FMGs perceived that the participatory forest management program ena-bled them to get benefits from the sale of fuelwood while performance scores in the forest conservation and decision-making processes is gener-ally poor. The score for economic performance of FMGs in turn was related to better access to roads and markets. Group size tended to en-hance economic performance via its strong influence on annual fuelwood harvest, while the resource base appeared to be inconsequential. Mem-bers of the forest management groups perceived that large group size and group heterogeneity, particularly in terms of ethnicity, as well as knowledge and awareness of problems related to the forest environment have no influence on the performance of their respective groups. For rural communities to have a favorable disposition toward sustainable forest management, differences in member understanding of collective actions and their impact before and during the implementation of partic-ipatory forest management programs should be considered.

    Full Text Available Reducing Emissions from Deforestation and Degradation (REDD+ is a policy instrument meant to mitigate climate change while also achieving poverty reduction in tropical countries. It has garnered critics for homogenising environmental and development governance and for ignoring how similar efforts have tended to exacerbate gender inequalities. Nonetheless, regarding such schemes as inevitable, some feminists argue for requirements that include women′s empowerment and participation. In this paper we move beyond discussions about safeguards and examine whether the very framing of REDD+ programs can provide openings for a transformation as argued for by its proponents. Following the REDD+ policy process in Burkina Faso, we come to two important insights: REDD+ is a solution in need of a problem. Assumptions about gender are at the heart of creating ′actionable knowledge′ that enabled REDD+ to be presented as a policy solution to the problems of deforestation, poverty and gender inequality. Second, despite its ′safeguards′, REDD+ appears to be perpetuating gendered divisions of labour, as formal environmental decision-making moves upwards; and responsibility and the burden of actual environmental labour shifts further down in particularly gendered ways. We explore how this is enabled by the development of policies whose stated aims are to tackle inequalities.

    Full Text Available Background: In several African cities the prevalence of unmarried cohabitation among youth has risen considerably. Because of its potentially negative implications for women and their children, in some countries cohabitation has even become a matter of heated public debate and policy concern. In contrast to industrialized countries, however, the choice between marriage and cohabitation in the region has attracted little attention. Objective: The purpose of the study is to explore the rising phenomenon of young, unmarried, cohabiting couples in Ouagadougou, the capital city of Burkina Faso, and to evaluate how characteristics of both partners involved in a dating relationship affect the choice between marriage and non-marital cohabitation when forming a first union. Methods: Based on life history data including unique relationship biographies, the study takes a competing risks approach to examine relationship transitions to a first marriage or unmarried cohabitation. Results: A long spell of unmarried cohabitation is common among youth in Ouagadougou today, and children's exposure to cohabitation is high. While occupation, especially male occupation, is a crucial determinant of entry into union - having a similar effect on marriage and cohabitation risks - partners' educational attainment, ethnic endogamy, and religion significantly affect the choice between marriage and cohabitation. Conclusions: Ideational changes rather than economic ones motivate youth to choose cohabitation instead of marriage. Cohabitation in Ouagadougou has not become the "poor man's wedding", as Oppenheimer's hypothesis would suggest, but rather the preferred choice of dating couples who are more willing and able to distance themselves from familial expectations and marital norms.

    Aqueous acetone extracts prepared from five Indigofera species of Burkina Faso, namely Indigofera colutea (Burm.) Murril., I. macrocalyx Guilld et Perr., I. nigritana Hook f., I. pulchra willd. and I. tinctoria L., were investigated for their phytochemical composition and their antioxidant activities. Standard methods and TLC were used to screen the phytochemical composition. The total phenolic and flavonoid content of extracts were assessed by Folin-Ciocalteu and AlCl3 methods, respectively. These extracts were also evaluated for their antioxidant potentials using ferric reducing antioxidant power (FRAP), 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azinobis(3-ethylbenzothiazoline-6-sulphonate) (ABTS) assays. Flavonoids, saponins, quinones, sterols/triterpenes and tannins were present in all these species except for I. pulchra where quinones were not found. Gallic acid, caffeic acid, rutin and myricetin in I. colutea; gallic acid, quercitrin, myricetin in I. tinctoria; galangin and myricetin in I. macrocalyx were identified by thin layer chromatography. Among these, I. colutea, I. tinctoria, I. nigritana and I. macrocalyx, which had the highest phenolic content, were also found to possess the best antioxidant activities. The results indicated a good correlation between antioxidant activities and total phenolic content (puses. PMID:18817242

    Full Text Available Objective. This study aimed to investigate the association between three polymorphisms of renin-angiotensin system and the essential hypertension in the population of Burkina Faso. Methodology. This was a case-control study including 202 cases and 204 matched controls subjects. The polymorphisms were identified by a classical and a real-time PCR. Results. The AGT 235M/T and AT1R 1166A/C polymorphisms were not associated with the hypertension while the genotype frequencies of the ACE I/D polymorphism between patients and controls (DD: 66.83% and 35.78%, ID: 28.22% and 50.98%, II: 4.95% and 13.24%, resp. were significantly different (p < 10−4. The genotype DD of ACE gene (OR = 3.40, p < 0.0001, the increasing age (OR = 3.83, p < 0.0001, obesity (OR = 4.84, p < 0.0001, dyslipidemia (OR = 3.43, p = 0.021, and alcohol intake (OR = 2.76, p < 0.0001 were identified as the independent risk factors for hypertension by multinomial logistic regression. Conclusion. The DD genotype of the ACE gene is involved in susceptibility to hypertension. Further investigations are needed to better monitor and provide individualized care for hypertensive patients.

    In the early 1980s, the situation on the northern part of the Central Plateau of Burkina Faso was characterized by expanding cultivation on lands marginal to agriculture, declining rainfall, low and declining cereal yields, disappearing and impoverishing vegetation, falling ground-water levels and strong outmigration. This crisis situation provoked two reactions. Farmers, as well as technicians working for non-governmental organizations, started to experiment in improving soil and water conservation (SWC) techniques. When these experiments proved successful, donor agencies rapidly designed SWC projects based on simple, effective techniques acceptable to farmers. A study looked at the impact of SWC investments in nine villages and identified a number of major impacts, including: significant increases in millet and sorghum yields since the mid-1980s, cultivated fields treated with SWC techniques have more trees than 10-15 years ago, but the vegetation on most of the non-cultivated areas continues to degrade, greater availability of forage for livestock, increased investment in livestock by men and women and a beginning change in livestock management from extensive to semi-intensive methods, improved soil fertility management by farmers, locally rising ground-water tables, a decrease in outmigration and a significant reduction in rural poverty. Finally, data are presented on the evolution of land use in three villages between 1968 and 2002. ?? 2005 Elsevier Ltd. All rights reserved.

    The regionally correlated and dated regolith-paleolandform sequence of Sub-Saharan West Africa offers a unique opportunity to constrain continental-scale regolith dynamics as the key part of the sediment routing system. In this study, a regolith mapping protocol is developed and applied at the scale of Southwestern Burkina Faso. Mapping combines field survey and remote sensing data to reconstruct the topography of the last pediplain that formed over West Africa in the Early and Mid-Miocene (24-11 Ma). The nature and preservation pattern of the pediplain are controlled by the spatial variation of bedrock lithology and are partitioned among large drainage basins. Quantification of pediplain dissection and drainage growth allows definition of a cratonic background denudation rate of 2 m/My and a minimum characteristic timescale of 20 Ma for shield resurfacing. These results may be used to simulate minimum export fluxes of drainage basins of constrained size over geological timescales. Background cratonic denudation results in a clastic export flux of ~ 4 t/km2/year, which is limited by low denudation efficiency of slope processes and correlatively high regolith storage capacity of tropical shields. These salient characteristics of shields' surface dynamics would tend to smooth the riverine export fluxes of shields through geological time.

    Full Text Available The aim of the present study was to evaluate some enzymes inhibitory effects of 11 plant species belonging to 9 families from Burkina Faso. Methanolic extracts were used for their Glutathione-s-transferase (GST, Acetylcholinesterase (AChE, Carboxylesterase (CES and Xanthine Oxidase (XO inhibitory activities at final concentration of 100 μg mL-1. The total phenolics, flavonoids and tannins were also determined spectrophotometrically using Folin-Ciocalteu, AlCl3 and ammonium citrate iron reagents, respectively. Among the 11 species tested, the best inhibitory percentages were found with Euphorbia hirta, Sclerocarya birrea and Scoparia dulcis (inhibition>40% followed by Annona senegalensis, Annona squamosa, Polygala arenaria and Ceratotheca sesamoides (inhibition>25%. The best total phenolic and tannin contents were found with S. birrea with 56.10 mg GAE/100 mg extract and 47.75 mg TAE/100 mg extract, respectively. E hirta presented the higher total flavonoids (9.96 mg QE/100 mg extract. It's was found that Sclerocarya birrea has inhibited all enzymes at more than 30% and this activity is correlated to total tannins contents. Contrary to S. birrea, the enzymatic activities of E. hirta and S. dulcis are correlated to total flavonoids contents. Present findings suggest that the methanolic extracts of those plant species are potential inhibitors of GST, AChE, CES and XO and confirm their traditional uses in the treatment of mental disorders, gout, painful inflammations and cardiovascular diseases.

    Full Text Available A survey of the parasites of abomasa, small, and large intestines of 94 bovines conveyed to the main slaughterhouse of Ouagadougou from the central and northern part of Burkina Faso allowed the identification of nine different worm species: Cooperia punctata, Cooperia pectinata, Haemonchus contortus, Trichostrongylus colubriformis, Bunostomum phlebotomum, Moniezia expensa, Avitellina sp., Oesophagostomum radiatum, and Trichuris sp. By far, Cooperia sp. was the most prevalent (89.4/, followed by H. contortus (66/, and O. radiatum (42.6/. The other worm species were much less prevalent. While only one cattle was free of parasites, it was noticed that polyparasitism was very common. There was a wide range of worm burden (0 to 42290 with however in most animals high worm numbers specially of Cooperia sp. This study confirmed that the rainy season constitutes a period of worm explosion. During the hot and dry season, H. contortus seemed primarily able to undergo arrested development in the L4 stage and secondarily to remain in the adult stage. Statistical analyses of levels of infestation did not show any significant difference according to age, sex, and weight of cattle.

    Objective:To identify Candida species in asymptomatic subjects in Bobo-Dioulasso (Burkina Faso) by the matrix-assisted laser desorption ionization-time of flight mass spectrometry. Methods: A cross-sectional study was conducted from January to February 2013 in Bobo-Dioulasso to collect fecal and urine specimens from voluntary donors. Fungal strains were isolated on Sabouraud dextrose agar and analyzed using matrix-assisted laser desorption ionisation-time-of-flight mass spectrometry. Results: A total of 135 samples including stools (78.5%, 106/135) and urine (21.5%, 29/135) were analyzed. The results revealed that fecal specimens contained mainly Candida krusei (C. krusei) (42.5%) followed by Candida albicans (29.3%), Candida glabrata (18.0%) and Candida tropicalis (C. tropicalis) (4.7%). C. krusei (34.6%) was also found to be the most frequently identified in urine samples followed by Candida albicans (27.0%), C. tropicalis (15.4%) and Candida parapsilosis. However, uncommon species such as Candida nivariensis, Candida kefyr, Candida norvegensis, Candida parapsilosis, Candida lusitaniae and Candida robusta were also identified from fecal and urines samples. Conclusions:This study noted the emergence of species such as C. krusei, Candida glabrata, Candida parapsiolosis, C. tropicalis, Candida nivariensis, Candida norvegensis, and others. It is an imperative to take into account the existence of these species in the therapeutic management of patients in Bobo-Dioulasso.

    Full Text Available Background: Obesity is a global epidemic that affects both developed and developing countries. According to World Health Organization (WHO, in 2014, over 1.9 billion adults were overweight. Burkina Faso, like other countries, faces the problem of obesity, with a prevalence of 7.3%. The main cause is excessive intake of caloric foods combined with low physical activity, although genetic, endocrine and environmental influences (pollution can sometimes be predisposing factors. This metabolic imbalance often leads to multiple pathologies (heart failure, Type II diabetes, cancers, etc.. Drugs have been developed for the treatment of these diseases; but in addition to having many side effects, locally these products are not economically accessible to the majority of the population. Burkina Faso, like the other countries bordering the Sahara, has often been confronted in the past with periods of famine during which populations have generally used anorectic plants to regulate their food needs. This traditional ethnobotanical knowledge has not been previously investigated. An ethnobotanical survey was conducted in Burkina Faso in the provinces of Seno (North and Nayala (Northwest to list the plants used by local people as an anorectic and/or fort weight loss. Methods: The survey, conducted in the two provinces concerned traditional healers, herbalists, hunters, nomads and resourceful people with knowledge of plants. It was conducted over a period of two months and data were collected following a structured interview with the respondents. The approach was based on dialogue in the language of choice of the respondent and the use of a questionnaire. The data have been structured and then statistically analyzed. Results: The fifty-five (55 respondents of the survey were aged between 40 and 80 years. Sixty-one (61 plant species, belonging to thirty-one (31 families were listed as appetite suppressants and/or for their anti-obesity properties. The main

    We examine how southwestern Burkina Faso populations interpret political ecological and social change for the past 40 years to assert a changing epidemiology of childhood "cold fevers"-malaria-like illnesses. Lay knowledge about "cold fevers" is historically produced, reflecting political economic, social, ecological and biomedical changes, and the historical consciousness of people living with these illnesses. While informants insisted that dislocations wrought by a post-colonial irrigation scheme increased cold fevers, they offered different explanations for their increased incidence and intensity. This historical epidemiology of cold fevers may influence parents' care decisions, but global public health interventions are rapidly changing therapeutic access. PMID:21507704

    Full Text Available We report herein the case of 19-year-old female farmer who suffered a double snakebite on the right foot. After an unsuccessful traditional treatment, she consulted a health center, 48 hours after the bite. Upon arrival at the hospital, she showed signs of severe damage, including hemorrhagic syndrome, extensive gangrene of the bitten limb and severe acute renal failure. Due to financial constraints, neither antivenom nor the scheduled amputation was performed. After 35 days of hospitalization, she returned home, against the advice of medical personnel. Our case summarizes the daily challenges of patients and practitioners that suffer snakebite envenomation in Bobo-Dioulasso, western Burkina Faso.

    Full Text Available Abstract Background Vitamin A (VA deficiency is widespread in sub-Saharan Africa and school-age children are a vulnerable group. In Burkina Faso, the production and consumption of red palm oil (RPO is being promoted as a food supplement for VA. The objective of the study was to assess the impact on serum retinol of adding RPO to school lunch in two test zones of Burkina Faso. Methods Over one school year, 15 ml RPO was added to individual meals 3 times a week in selected primary schools in two sites. Serum retinol was measured with HPLC at baseline and exactly 12 months later to take account of seasonality. A simple pre-post test design was used in the Kaya area (north-central Burkina, where 239 pupils from 15 intervention schools were randomly selected for the evaluation. In Bogandé (eastern Burkina, 24 schools were randomised for the controlled intervention trial: 8 negative controls (G1 with only the regular school lunch; 8 positive controls (G2 where the pupils received a single VA capsule (60 mg at the end of the school year; and 8 schools with RPO through the school year (G3. A random sample of 128 pupils in each school group took part in the evaluation. Results In Kaya, serum retinol went from 0.77 ± 0.37 μmol/L at baseline to 1.07 ± 0.40 μmol/L one year later (p Conclusion RPO given regularly in small amounts appears highly effective in the reduction of VA deficiency. RPO deserves more attention as a food supplement for VA and as a potential source of rural income in Sahelian countries.

  11. Re-greening the Sahel: farmer-led innovation in Burkina Faso and Niger

    2009-01-01

    The Sahel—the belt of land that stretches across Africa on the southern edge of the Sahara—has always been a tough place to farm. Rainfall is low and droughts are frequent. The crust of hard soil is, at times, almost impermeable, and harsh winds threaten to sweep away everything in their path. Over the past three decades, however, hundreds of thousands of farmers in Burkina Faso and Niger have transformed large swaths of the region’s arid landscape into productive agricultural land, improving food security for about 3 million people. Once-denuded landscapes are now home to abundant trees, crops, and livestock. Although rainfall has improved slightly from the mid-1990s relative to earlier decades, indications are that farmer management is a stronger determinant of land and agroforestry regeneration. Sahelian farmers achieved their success by ingeniously modifying traditional agroforestry, water, and soil-management practices. To improve water availability and soil fertility in Burkina Faso’s Central Plateau, farmers have sown crops in planting pits and built stone contour bunds, which are stones piled up in long narrow rows that follow the contours of the land in order to capture rainwater runoff and soil. These practices have helped rehabilitate between 200,000 and 300,000 hectares of land and produce an additional 80,000 tons of food per year. In southern Niger, farmers have developed innovative ways of regenerating and multiplying valuable trees whose roots already lay underneath their land, thus improving about 5 million hectares of land and producing more than 500,000 additional tons of food per year. While the specific calculations of farm-level benefits are subject to various methodological and data limitations, the order of magnitude of these benefits is high, as evidenced by the wide-scale adoption of the improved practices by large numbers of farmers. Today, the agricultural landscapes of southern Niger have considerably more tree cover than they

    2012-12-01

    Full Text Available Abstract Background As more point of care diagnostics become available, the need to transport and store perishable medical commodities to remote locations increases. As with other diagnostics, malaria rapid diagnostic tests (RDTs must be highly reliable at point of use, but exposure to adverse environmental conditions during distribution has the potential to degrade tests and accuracy. In remote locations, poor quality diagnostics and drugs may have significant negative health impact that is not readily detectable by routine monitoring. This study assessed temperature and humidity throughout supply chains used to transport and store health commodities, such as RDTs. Methods Monitoring devices capable of recording temperature and humidity were deployed to Burkina Faso (8, Senegal (10, Ethiopia (13 and the Philippines (6 over a 13-month period. The devices travelled through government supply chains, usually alongside RDTs, to health facilities where RDTs are stored, distributed and used. The recording period spanned just over a year, in order to avoid any biases related to seasonal temperature variations. Results In the four countries, storage and transport temperatures regularly exceeded 30.0°C; maximum humidity level recorded was above 94% for the four countries. In three of the four countries, temperatures recorded at central storage facilities exceeded pharmaceutical storage standards for over 20% of the time, in another case for a majority of the time; and sometimes exceeded storage temperatures at peripheral sites. Conclusions Malaria RDTs were regularly exposed to temperatures above recommended limits for many commercially-available RDTs and other medical commodities such as drugs, but rarely exceeded the recommended storage limits for particular products in use in these countries. The results underline the need to select RDTs, and other commodities, according to expected field conditions, actively manage the environmental conditions in

  13. Effective population size of Anopheles funestus chromosomal forms in Burkina Faso

    Costantini Carlo

    2006-11-01

    Full Text Available Abstract Background As Anopheles funestus is one of the principal Afro-tropical malaria vectors, a more complete understanding of its population structure is desirable. In West and Central Africa, An. funestus population structure is complicated by the coexistence of two assortatively mating chromosomal forms. Effective population size (Ne is a key parameter in understanding patterns and levels of intraspecific variation, as it reflects the role of genetic drift. Here, Ne was estimated from both chromosomal forms, Kiribina and Folonzo, in Burkina Faso. Methods Short-term Ne was estimated by evaluating variation at 16 microsatellite loci across temporal samples collected annually from 2000–2002. Estimates were based on standardized variance in allele frequencies or a maximum likelihood method. Long-term Ne was estimated from genetic diversity estimates using mtDNA sequences and microsatellites. Results For both forms, short-term and long-term Ne estimates were on the order of 103 and 105, respectively. Long-term Ne estimates were larger when based on loci from chromosome 3R (both inside and outside of inversions than loci outside of this arm. Conclusion Ne values indicate that An. funestus is not subject to seasonal bottlenecks. Though not statistically different because of large and overlapping confidence intervals, short-term Ne estimates were consistently smaller for Kiribina than Folonzo, possibly due to exploitation of different breeding sites: permanent for Folonzo and intermittent for Kiribina. The higher long-term Ne estimates on 3R, the arm carrying the two inversions mainly responsible for defining the chromosomal forms, give natural selection broader scope and merit further study.

    2013-10-01

    Full Text Available Background: Family structure and union dissolution has been one of the most thoroughly studied determinants of children's wellbeing worldwide. To date, however, few of these studies have examined sub-Saharan Africa, especially countries in West Africa where marital breakdowns are not uncommon. Objective: We attempt to examine the effects of a mother's divorce and widowhood on children's risk of mortality under age 5 and on their probability of entering primary school. Methods: Survival data analysis methods, specifically Kaplan-Meier and piecewise exponential models, are used for analysis, based on data come from the 2000 Migration and Urban Integration Survey of Burkina Faso. Results: Compared to those of intact families, children of divorced parents experience higher estimated mortality risks under age 5 and a lower probability of entering school, even after controlling for various other factors. This effect is large and significant during the first two years after the divorce. The death of the father is also found to greatly reduce a child's likelihood of entering school, but its effect on mortality is not significant. Conclusions: The results indicate that the family context plays an important role in determining two important aspects of children's welfare: their probabilities of dying before age 5 and of entering school. Comments: Children of divorced parents or a deceased father are living in precarious situations and their specific needs should be taken into account in policies in order to improve the wellbeing of all children. Attention must be directed to the first two years following the union dissolution.

    We study the spatial geography of schistosomiasis in the african context of Burkina Faso by means of a spatially explicit model of disease dynamics and spread. The relevance of our work lies in its ability to describe quantitatively a geographic stratification of the disease burden capable of reproducing important spatial differences, and drivers/controls of disease spread. Among the latters, we consider specifically the development and management of water resources which have been singled out empirically as an important risk factor for schistosomiasis. The model includes remotely acquired and objectively manipulated information on the distributions of population, infrastructure, elevation and climatic drivers. It also includes a general description of human mobility and addresses a first-order characterization of the ecology of the intermediate host of the parasite causing the disease based on maximum entropy learning of relevant environmenal covariates. Spatial patterns of the disease were analyzed about their disease-free equilibrium by proper extraction and mapping of suitable eigenvectors of the Jacobian matrix subsuming all stability properties of the system. Human mobility was found to be a primary control of both pathogen invasion success and of the overall distribution of disease burden. The effects of water resources development were studied by accounting for the (prior and posterior) average distances of human settlements from water bodies that may serve as suitable habitats to the intermediate host of the parasite. Water developments, in combination with human mobility, were quantitatively related to disease spread into regions previously nearly disease-free and to large-scale empirical incidence patterns. We concluded that while the model still needs refinements based on field and epidemiological evidence, the framework proposed provides a powerful tool for large-scale, long-term public health planning and management of schistosomiasis.

    Full Text Available Background: Resistance of malaria parasites to existing drugs complicates treatment, but an antimalarial vaccine that could protect against this disease is not yet available. It is therefore necessary to find new effective and affordable medicines. Medicinal plants could be a potential source of antimalarial agents. Some medicinal plants from Burkina Faso were evaluated for their antiplasmodial and cytotoxic properties in vitro.Methods: Crude dichloromethane, methanol, water-methanol, aqueous and alkaloids extracts were prepared for 12 parts of 10 plants. Chloroquine-resistant malaria strain K1 was used for the in vitro sensibility assay. The Plasmodium lactacte dehydrogenase technique was used to determine the 50% inhibitory concentration of parasites activity (IC50. The cytotoxic effects were determined with HepG2 cells, using the tetrazolium-based colorimetric technique, and the selectivity index (SI was calculated.Results: Sixty crude extracts were prepared. Seven extracts from Terminalia avicenoides showed IC50 < 5 µg/mL. The IC50 of dichloromethane, methanol, aqueous and alkaloids extracts ranged between 1.6 µg/mL and 4.5 µg/mL. Three crude extracts from Combretum collinum and three from Ficus capraefolia had an IC50 ranging between 0.2 µg/mL and 2.5 µg/mL. Crude extracts from these three plants had no cytotoxic effect, with SI > 1. The other plants have mostly moderate or no antimalarial effects. Some extracts from Cordia myxa, Ficus capraefolia and Opilia celtidifolia showed cytotoxicity, with an SI ranging between 0.4 and 0.9.Conclusion: Our study showed a good antiplasmodial in vitro activity of Terminalia avicenoides, Combretum collinum and Ficus capraefolia. These three plants may contain antiplasmodial molecules that could be isolated by bio-guided phytochemical studies.

    Poverty at the national and sub-national level is commonly mapped on the basis of household surveys. Typical poverty metrics like the head count index are not able to identify its underlaying factors, particularly in rural economies based on subsistence agriculture. This paper relates agro-ecological marginality identified from regional and global datasets including remote sensing products like the normalized difference vegetation index (NDVI) and rainfall to rural agricultural production and food consumption in Burkina Faso. The objective is to analyze poverty patterns and to generate a fine resolution poverty map at the national scale. We compose a new indicator from a range of welfare indicators quantified from Georeferenced household surveys, indicating a spatially varying set of welfare and poverty states of rural communities. Next, a local spatial regression is used to relate each welfare and poverty state to the agro-ecological marginality. Our results show strong spatial dependency of welfare and poverty states over agro-ecological marginality in heterogeneous regions, indicating that environmental factors affect living conditions in rural communities. The agro-ecological stress and related marginality vary locally between rural communities within each region. About 58% variance in the welfare indicator is explained by the factors of rural agricultural production and 42% is explained by the factor of food consumption. We found that the spatially explicit approach based on multi-temporal remote sensing products effectively summarizes information on poverty and facilitates further interpretation of the newly developed welfare indicator. The proposed method was validated with poverty incidence obtained from national surveys.

    Full Text Available Understanding land cover degradation patterns and the effects of geomorphological units on phytodiversity is important for guiding management decisions and restoration strategies in the Sahelian vulnerables zones. This paper describes land cover degradation by combining Landsat TM image analysis and field data measurements in the Gourouol catchment of the Sahelian zone of Burkina Faso. Erdas Imagine 9.2 and Arc-GIS.10 were applied. The change patterns were obtained by superposing land cover maps for 1992 and 2010. The field data were collected by the mean of inventories according to the Braun-Blanquet phytosociological relevés methods. Plot sizes were 50 m x 20 m for woody species and 10 m x 10 m for herbaceous species. Six land cover types were identified and mapped: cultivated lands, bared lands, lowlands, which all spatially increased; and shrub-steppes, grasslands and water bodies, which all spatially decreased. The dynamic patterns based on the geomorphological units were non-degraded lowlands, stable sand dunes and degraded glacis. High plant diversity was found in lowlands, whereas low diversity occurred in glacis. A significant dissimilarity was observed between communities. The Shannon diversity indices in plant communities were approximately close to ln(species richness. The Pielou indices were close to 1, indicating a species fairly good distribution. Our results showed a variation of land cover over time and the effects of geomorphological units on phytodiversity. Furthermore, this variation helps oppose land degradation in the Sahel.

    In this study, the authors investigate farmers’ vulnerability to climate variability and evaluate local adoption of technology and farmers’ perceptions of adaptation strategies to rainfall variability and policies. A survey was conducted in a community in northern Burkina Faso following the crop failure of 2004. In 2006, following a better harvest, another survey was conducted to compare farmers’ actions and reactions during two contrasted rainy seasons. The results confirm that farmers from this community have substantially changed their practices during the last few decades. They have adopted a wide range of techniques that are intended to simultaneously increase crop yield and reduce yield variability. Micro water harvesting (Zaï) techniques have been widely adopted (41%), and a majority of fields have been improved with stone lines (60%). Hay (48%) and sorghum residues are increasingly stored to feed animals during the dry season, making bull and sheep fattening now a common practice. Dry season vegetable production also involves a majority of the population (60%). According to farmers, most of the new techniques have been adopted because of growing land scarcity and new market opportunities, rather than because of climate variability. Population pressure has reached a critical threshold, while land scarcity, declining soil fertility and reduced animal mobility have pushed farmers to intensify agricultural production. These techniques reduce farmers’ dependency on rainfall but are still insufficient to reduce poverty and vulnerability. Thirty-nine percent of the population remains vulnerable after a good rainy season. Despite farmers’ desire to remain in their own communities, migrations are likely to remain a major source of regular income and form of recourse in the event of droughts.

  20. Local Water Management of Small Reservoirs: Lessons from Two Case Studies in Burkina Faso

    Directory of Open Access Journals (Sweden)

    2011-10-01

    Full Text Available Burkina Faso is actively pursuing the implementation of Integrated Water Resources Management (IWRM in its development plans. Several policy and institutional mechanisms have been put in place, including the adoption of a national IWRM action plan (PAGIRE and the establishment so far of 30 local water management committees (Comités Locaux de l’Eau, or CLE. The stated purpose of the CLE is to take responsibility for managing water at sub-basin level. The two case studies discussed in this paper illustrate gaps between the policy objective of promoting IWRM on the one hand, and the realities associated with its practical on-the-ground implementation on the other. A significant adjustment that occurred in practice is the fact that the two CLE studied have been set up as entities focused on reservoir management, whereas it is envisioned that a CLE would constitute a platform for sub-basin management. This reflects a concern to minimise conflict and optimally manage the country’s primary water resource and illustrates the type of pragmatic actions that have to be taken to make IWRM a reality. It is also observed that the local water management committees have not been able to satisfactorily address questions regarding access to, and allocation of, water, which are crucial for the satisfactory functioning of the reservoirs. Water resources in the reservoirs appear to be controlled by the dominant user. In order to correct this trend, measures to build mutual trust and confidence among water users 'condemned' to work together to manage their common resource are suggested, foremost of which is the need to collect and share reliable data. Awareness of power relationships among water user groups and building on functioning, already existing formal or informal arrangements for water sharing are key determinants for successful implementation of the water reform process underway.

  1. HIV testing and care in Burkina Faso, Kenya, Malawi and Uganda: ethics on the ground

    2013-01-01

    Full Text Available Abstract Background The ethical discourse about HIV testing has undergone a profound transformation in recent years. The greater availability of antiretroviral therapy (ART has led to a global scaling up of HIV testing and counseling as a gateway to prevention, treatment and care. In response, critics raised important ethical questions, including: How do different testing policies and practices undermine or strengthen informed consent and medical confidentiality? How well do different modalities of testing provide benefits that outweigh risks of harm? To what degree do current testing policies and programs provide equitable access to HIV services? And finally, what lessons have been learned from the field about how to improve the delivery of HIV services to achieve public health objectives and protections for human rights? This article reviews the empirical evidence that has emerged to answer these questions, from four sub-Saharan African countries, namely: Burkina Faso, Kenya, Malawi and Uganda. Discussion Expanding access to treatment and prevention in these four countries has made the biomedical benefits of HIV testing increasingly clear. But serious challenges remain with regard to protecting human rights, informed consent and ensuring linkages to care. Policy makers and practitioners are grappling with difficult ethical issues, including how to protect confidentiality, how to strengthen linkages to care, and how to provide equitable access to services, especially for most at risk populations, including men who have sex with men. Summary The most salient policy questions about HIV testing in these countries no longer address whether to scale up routine PITC (and other strategies, but how. Instead, individuals, health care providers and policy makers are struggling with a host of difficult ethical questions about how to protect rights, maximize benefits, and mitigate risks in the face of resource scarcity.

  2. First assessment of individual monitoring of medical workers occupationally exposed to ionizing radiation in Burkina Faso

    International Nuclear Information System (INIS)

    This paper reports the results of monitoring of medical workers occupationally exposed to ionizing radiation as a consequence of exposure to X-rays, from 2007 to 2010, in Burkina Faso. The radiation exposure monitoring was made with thermoluminescent dosimeters (TLD-100) type 0110 and the reader used was Harshaw 4500. The medical establishments. subscribers were provided with personal dosimeters (measuring Hp (10) and Hp (0.07)) and dosimeters for background and workplace exposure (H*10) measurement. The dosimeters have been worn for periods of 2 months each. The number of establishments subscribed and workers monitored has gradually increased from 4 radiology establishments with 13 workers monitored at September 2007 to 23 subscribers with 121 workers monitored at the end of April 2010. 13 establishments were still working without monitoring. From September 2007 to April 2010, no individual annual dose limit has really been reached. 88.16% of the 2 months dose values of personal dosimeters were below 0.1mSv, the detection limit and 96.61% of Hp (10) bimonthly values were below 3.33mSv. The workplace exposure monitoring values were often low (varying from 0.00mSv to 40.45mSv). 87.08% of the values of H*(10) were below 3.33mSv, the upper limit of Hp (10) for a period of 2 months. Low values of individual dose have also been recorded despite of high values of workplace monitoring. This allowed to state that the workers monitored were not exposed to a major risk. Nevertheless, 13 TLD have been lost and 3 damaged by subscribers (out of 1504 TLD provided). 26 times (out of 240), background measurement and workplace exposure monitoring dosimeters have been placed at the improper location. Therefore, sensitization of the establishments using ionizing radiation should be reinforced and the national regulations should impose radiation monitoring (author)

  3. The question of the renewal of groundwater resources in southwestern Burkina Faso

    International Nuclear Information System (INIS)

    South-West Burkina Faso (60 000 km2) is located in the upstream parts at the junction of the water basins of the rivers Comoe, Volta and Niger. The mean precipitation value is around 1000 mm in one rainy season (monsoon) starting April and finishing October. More than 80% of precipitation occur between June and August. In our area two great lithological units are encountered: the sedimentary deposits in the West, mainly sandstones of the Upper Precambrian and the crystalline and metamorphic substratum in the East. Our main concern dealt with the sedimentary aquifers within 9 well defined geological formations on the edge of the Taoudeni basin dipping less than 10o NNW. These watersheds have an important hydric potential in surface waters as well as in groundwaters and still embrace nowadays relatively important reclamation lands. The physical context and the water reserve in the southwest present a possibility of expansion and development which has already started being exploited. Since 1970 this region has undertaken an intense activity of mobilization and use of the waters. It has been noted that the managing and exploitation of the important natural potential occurs spontaneously and/or individually without enough critical concern related to the needs and the resources. This situation has already led in some places to shortages, conflicts about the uses and risks of overexploitation of the areas and in an inadequate use of the reclamation lands. This situation implies serious problems as to the qualitative protection of the resource. This inappropriate approach is the consequence of an incomplete knowledge of the water resources. Today new demands arise as to the mobilization the use of the groundwater resources and to the qualitative protection. In order to solve these problems as quickly as possible, from 1997 to 1999 isotopic investigation have been undertaken (18O enables to identify the recharge areas. 14C and 3H define the ''age'' of the water)

    The major part of the population of Ouagadougou, Burkina Faso, have their breakfast, dinner and lunch in street food shops. The characteristics of street food vendors are indicated. It appeared clearly that women play a major part (75%) in street food sale. Vendors have only a slight knowledge of food processing and of hygienic practices. There is a high proportion (about 50%) of people among them. This dietary habit has some negative aspects on the consumers' health. Ours studies clearly showed that hygienic practices during sales operations are not respected by all categories of vendors of food products. Also, it was observed that street food vendors sometimes sit close to the waste water drainage system and solid wastes. Sometimes, the food is not covered and it is manipulated by consumers in areas infested by flies and others insects. The water used to wash the materials is of poor quality. The second aspects of our studies showed that, in most cases, when the safety and hygienic practices were not respected, the food became a true microorganism culture medium under tropical climatic conditions. A table reports microbial analysis and contamination rates of some important street foods consumed in Ouagadougou. In general these results showed the failure of microbial quality of some food which is not preheated (milk product, fruit juice, vegetable, fruit) and in the case of food which is not reheated after a long time of exposition (dry meat and meat on sticks). The presence of Salmonella and Shigella species in some food represents a serious danger for consumers. These aspects were observed with most street food vendors. It probably makes street food the source of most diseases caused by bacteria and other microorganisms. PMID:12626290

    Full Text Available Abstract Background A well-functioning referral system is fundamental to primary health care delivery. Understanding the providers' referral decision-making process becomes critical. This study's aim was to assess the correctness of diagnoses and appropriateness of the providers' referral decisions from health centers (HCs to district hospitals (DHs among patients with severe malaria and pneumonia. Methods A record review of twelve months of consultations was conducted covering eight randomly selected HCs to identify severe malaria (SM cases among children under five and pneumonia cases among adults. The correctness of the diagnosis and appropriateness of providers' referral decisions were determined using the National Clinical Guidebook as a 'gold standard'. Results Among the 457 SM cases affecting children under five, only 66 cases (14.4% were correctly diagnosed and of those 66 correctly diagnosed cases, 40 cases (60.6% received an appropriate referral decision from their providers. Within these 66 correctly diagnosed SM cases, only 60.6% were appropriately referred. Among the adult pneumonia cases, 5.9% (79/1331 of the diagnoses were correctly diagnosed; however, the appropriateness rate of the provider's referral decision was 98.7% (78/79. There was only one case that should not have been referred but was referred. Conclusions The adherence to the National Guidelines among the health center providers when making a diagnosis was low for both severe malaria cases and pneumonia cases. The appropriateness of the referral decisions was particularly poor for children with severe malaria. Health center providers need to be better trained in the diagnostic process and in disease management in order to improve the performance of the referral system in rural Burkina Faso.

    Insecticidal activity of eight plants collected from Burkina Faso was studied using mosquito (Ochlerotatus triseriatus), Helicoverpa zea and Heliothis virescens larvae and adult white fly (Bemisia tabaci). The n-hexane, ethyl acetate and methanol extracts of Pseudocedrela kotschyi, Strophantus hispidus, Securidaca longepedunculata, Sapium grahamii, Swartzia madagascariensis, Cassia nigricans, Jatropha curcas and Datura innoxia were used in this study. Extracts were tested at 250 microg/mL concentration. All three extracts of C. nigricans, J. curcas (skin and seeds) and D. innoxia exhibited 100% mortality on fourth instar mosquito (O. triseriatus) larvae. In addition, the n-hexane and ethyl acetate extracts of S. hispidus, S. longepedunculata, S. grahamii showed 100% mortality. The ethyl acetate extract of S. madagascariensis was the most active on adult white fly and exhibited 80% mortality. Extracts of all other plants exhibited 30-50% mortality on B. tabaci. In the antifeedant assays against H. zea and H. virescens, the MeOH extracts of C. nigricans, S. madagascarensis and S. hispidus were more effective against H. zea as indicated by 74% larval weight reduction as compared to the control. Since C. nigricans is commonly used in West Africa to protect grain storage from insects, we have characterized the insecticidal components present in its extract. Bioassay directed isolation of C. nigricans leaf extract yielded anthraquinones emodin, citreorosein, and emodic acid and a flavonoid, luteolin. Emodin, the most abundant and active anthraquinone in C. nigricans showed approximately 85% mortality on mosquito larvae Anopheles gambiaea and adult B. tabaci at 50 and 25 microg/mL, respectively, in 24 h. These results suggest that the extract of C. nigricans has the potential to be used as an organic approach to manage some of the agricultural pests. PMID:17478091

    In South-West of Burkina Faso, palm wine is produced by spontaneous fermentation of the sap from a specific palm tree Borassus akeassii and plays an important role in people's lives. Saccharomyces cerevisiae is the main agent of this alcoholic fermentation but little is known about the diversity of the isolates from palm. In this work, 39 Saccharomyces cerevisiae strains were isolated from palm wine samples collected from 14 sites in Burkina Faso, as well as 7 isolates obtained from sorghum beer (Dolo) from 3 distant sites. Their diversity was analyzed at 12 microsatellite loci, and compared to the genotypes obtained for other African yeast populations isolated from Cocoa hulks from Ghana, sorghum beer from Ivory Coast, palm wine from Djibouti Republic, and to our database of strains from miscellaneous origins (bread, beer, wine, sake, oaks…). The ploidy of these strains has been assessed as well by flow cytometry. Our results show that B. akeassii palm wine contains a specific yeast population of diploid strains, different from Dolo produced in the same area and from other palm wine strains from Ivory Coast, Nigeria, or Djibouti Republic. In contrast, Dolo strains appeared as a group of related and mainly tetraploid strains despite being isolated from different countries. PMID:26202324

    A 35-month cluster randomized controlled trial was conducted in Burkina Faso to test whether a radio campaign focused on child health, broadcast between March 2012 and January 2015, could reduce under-5 mortality. This paper describes the design and implementation of the mass media intervention in detail, including the Saturation+ principles that underpinned the approach, the creative process, the lessons learned, and recommendations for implementing this intervention at scale. The Saturation+ approach focuses on the 3 core principles of saturation (ensuring high exposure to campaign messages), science (basing campaign design on data and modeling), and stories (focusing the dramatic climax on the target behavior) to maximize the impact of behavior change campaigns. In Burkina Faso, creative partnerships with local radio stations helped us obtain free airtime in exchange for training and investing in alternative energy supplies to solve frequent energy problems faced by the stations. The campaign used both short spots and longer drama formats, but we consider the short spots as a higher priority to retain during scale-up, as they are more cost-effective than longer formats and have the potential to ensure higher exposure of the population to the messages. The implementation research synthesized in this paper is designed to enable the effective adoption and integration of evidence-based behavior change communication interventions into health care policy and practice.

    In Burkina Faso, abortion is legally restricted and socially stigmatised, but also frequent. Unsafe abortions represent a significant public health challenge, contributing to the country's very high maternal mortality ratio. Inspired by an internationally disseminated public health framing of unsafe abortion, the country's main policy response has been to provide post-abortion care (PAC) to avert deaths from abortion complications. Drawing on ethnographic research, this article describes how Burkina Faso's PAC policy emerged at the interface of political and moral negotiations between public health professionals, national bureaucrats and international agencies and NGOs. Burkinabè decision-makers and doctors, who are often hostile to induced abortion, have been convinced that PAC is 'life-saving care' which should be delivered for ethical medical reasons. Moreover, by supporting PAC they not only demonstrate compliance with international standards but also, importantly, do not have to contend with any change in abortion legislation, which they oppose. Rights-based international NGOs, in turn, tactically focus on PAC as a 'first step' towards their broader institutional objective to secure safe abortion and abortion rights. Such negotiations between national and international actors result in widespread support for PAC but stifled debate about further legalisation of abortion. PMID:25132157

    The present study evaluates the predictive accuracy of the feed forward backpropagation artificial neural network (BP) in evapotranspiration forecasting from temperature data basis in Dédougou region located in western Burkina Faso, sub-Saharan Africa. BP accuracy is compared to the conventional Blaney–Criddle (BCR) and Reference Model developed for Burkina Faso (RMBF) by referring to the FAO56 Penman–Monteith (PM) as the standard method. Statistically, the models accuracies were evaluated with the goodness-of-fit measures of root mean square error, mean absolute error and coefficient of determination between their estimated and PM observed values. From the statistical results, BP shows similar contour trends to PM, and performs better than the conventional methods in reference evapotranspiration (ET_ref) forecasting in the region. In poor data situation, BP based only on temperature data is much more preferred than the other alternative methods for ET_ref forecasting. Furthermore, it is noted that the BP network computing technique accuracy improves significantly with the addition of wind velocity into the network input set. Therefore, in the region, wind velocity is recommended to be incorporated into the BP model for high accuracy management purpose of irrigation water, which relies on accurate values of ET_ref.

    The influence of vetiver grass (Vetiveria zizanioides) on the fate of endosulfan was studied using a vertisol and a lixisol soils from cotton-growing areas of Burkina Faso. Endosulfan adsorption isotherms were prepared for planted and unplanted soils. Pot experiments were then conducted for six months. For both soils, endosulfan adsorption was higher on planted soils (K(f) = 6.53-9.73 mg(l-n) L(n) kg(-1)) than on unplanted soils (6.27-7.24 mg(l-n) L(n) kg(-1)). In unplanted soils, vertisol adsorbed more endosulfan than lixisol. From the pot experiments, the estimated half-lives of endosulfan in unplanted soils (40.6 to 43.1 days) were higher than in planted soils (34.5 to 40.6 days) containing a greater number of endosulfan-degrading microorganisms. Six months after treatment, endosulfan was not detected in soils. The effectiveness of vetiver in promoting adsorption and the disappearance of endosulfan in both studied soils should be validated on the cotton plot scale in Burkina Faso. PMID:24912218

    Full Text Available Use of Wild Plants Species in Three Adjoining Village Southern Burkina Faso. Wild species are very important for people in developing countries. To enrich the knowledge of useful wild species, series of ethnobotanical surveys was conducted in three adjoining villages of southern Burkina Faso. This survey has permitted to identify 147 species distributed in 117 genera and 52 families. Woody species represent 60% and grass 40%. Fifty percent of the species used belong to seven families: Poaceae, Caesalpiniaceae, Combretaceae, Mimosaceae, Rubiaceae, Fabaceae and Anacardiaceae. Ninety-seven species are used in medicines, 47 for crafts, 46 for cattle feeding, 40 for human nutrition and 21 to provide fire. In all plants use categories, the calculation of index values showed that there are species that are used more than others. Thus, Sarcocephalus latifolius is the species most commonly used in medicines, Parkia biglobosa in human nutrition, Afzelia africana in cattle feeding, Vitellaria paradoxa in crafts and Detarium microcarpum in wood fuel. The evaluation of the diversity of use revealed that wood species have high diversity of uses than herbaceous. V. paradoxa is the species most diversely used. The top five most used species are V. paradoxa, P. biglobosa, Khaya senegalensis, Tamarindus indica and A. africana. The results of this study provide a database to assess the availability and the evolutionary trend of species widely used in the locality.

    Full text: Dispersion of riverine forest Glossina species is of great interest since they are the main cyclical vectors of human and animal trypanosomes in Africa. Design of control and/or eradication programmes requires an accurate knowledge of tsetse ecological preferences and the geographic structure of their populations. In West Africa, in the north of their distribution area, tsetse flies are submitted to the fragmentation of their environments. The level of fragmentation can be estimated from the migration rates between subpopulations. For this purpose, both mark-release field experiments as well as population genetics analyses are the favoured tools. The present study attempts to model the evolution of riverine tsetse flies dispersal in a gallery forest. For savannah species, evolution of tsetse flies dispersal is usually modelled as a two-dimensional random walk (in discrete time and space) or diffusion (its continuous analogue). For riverine species, it could similarly be viewed as one-dimensional random walk. We show that the topology of the whole gallery forest, which is rather a network of tributaries than a straight line, must be taken into account. Moreover, since only a part of the network can be considered in practice, we quantified the effect of partial observation when estimating dispersal parameters. We illustrate these results with a data set from a mark-release experiment carried out with Glossina palpalis gambiensis on a tributary of the Mouhoun River in Burkina Faso. The mark-release protocol is presented. The topology of the gallery is obtained from landsat 7 TM data and modelled as a tree. The predictions of three different models (isotropic and non isotropic random walks on a straight line, isotropic random walk on a network) are compared to field data. The effect of variations in the diffusion coefficient and daily mortality rate on the latter model is analysed. Finally the model is fitted on field data and used to estimate the

    L'objectif principal de cette recherche est la mise au point d'une architecture d'integration de donnees socio-bio-geographiques et de donnees satellitales dans un Systeme d'Information Geographique (SIG) en vue d'une aide a la prise de decisions dans un environnement semi-aride au nord du Burkina Faso. Elle repond a la question fondamentale de l'interpretation des effets des facteurs climatiques et socioeconomiques sur le milieu pastoral. La recherche s'est appuyee sur plusieurs hypotheses de travail: possibilite d'utilisation de modele de simulation, d'approche multicritere et de donnees de teledetection dans un cadre de systeme d'information geographique. L'evolution spatiotemporelle des parametres de productivite du milieu a ete evaluee par approche dynamique selon le modele de Wu et al. (1996) qui modelise les interactions entre le climat, le milieu physique, le vegetal et l'animal pour mieux quantifier la biomasse primaire. A ce modele, quatre parametres ont ete integres par approche floue et multicritere afin de prendre en compte la dimension socioeconomique de la productivite pastorale (apport majeur de la recherche): la sante, l'education, l'agriculture et l'eau. La teledetection (imagerie SPOT) a permis de definir la production primaire a partir de laquelle les simulations ont ete realisees sur 10 annees. Les resultats obtenus montrent une bonne correlation entre biomasse primaire in situ et celle calculee pour les deux modeles, avec toutefois une meilleure efficacite du modele modifie (4 fois plus) dans les zones de forte productivite ou l'on note un taux de surexploitation agricole eleve. A cause de la variabilite spatiale de la production primaire in situ, les erreurs des resultats de simulation (8 a 11%) sont acceptables et montrent la pertinence de l'approche grace a l'utilisation des SIG pour la spatialisation et l'integration des differents parametres des modeles.

    Policy entrepreneurs are individuals who attempt to influence the policy process and its outcomes through their opportunistic or incremental actions. Their success in the policy-making process has been associated with the convergence of four factors: behavioural traits; institutional factors; network position and political capital. Policy entrepreneurs have received little study in low- and middle-income country policy research despite observations of individualized decision-making, informal institutions and the unequal distribution and exercise of power in policymaking. This article aims to identify whether policy entrepreneurs were present in the policy process around integrated community case management (iCCM) in Burkina Faso, whether they were successful in achieving policy change, and whether success or failure can be explained using existing policy entrepreneur frameworks from high-income polities. This mixed methods policy study collected data from in-depth qualitative interviews and social network surveys of actors involved in iCCM policymaking [known locally as C-integrated management of childhood illness (IMCI)]; data were analysed based on the framework categories. Interview data pointed to one key individual who played a significant role in the inclusion of pneumonia treatment into the country's iCCM policy, an issue that had been a point of contention between government policy elites and development partners. Social network data confirmed that this actor was strategically located in the policy network to be able to reach the most other actors and to be able to control the flow of information. Although some development partner actors were as strategically located, none had the same level of authority or trust as was imbued by being a member of the government civil service. The entrepreneur's mid-level rank in the health ministry may have encouraged him/her to invest political capital and take risks that would not have been feasible or attractive to a

    Full Text Available Abstract Background In the rural areas of sub-Saharan Africa, the majority of young children affected by malaria have no access to formal health services. Home treatment through mothers of febrile children supported by mother groups and local health workers has the potential to reduce malaria morbidity and mortality. Methods A cluster-randomized controlled effectiveness trial was implemented from 2002–2004 in a malaria endemic area of rural Burkina Faso. Six and seven villages were randomly assigned to the intervention and control arms respectively. Febrile children from intervention villages were treated with chloroquine (CQ by their mothers, supported by local women group leaders. CQ was regularly supplied through a revolving fund from local health centres. The trial was evaluated through two cross-sectional surveys at baseline and after two years of intervention. The primary endpoint of the study was the proportion of moderate to severe anaemia in children aged 6–59 months. For assessment of the development of drug efficacy over time, an in vivo CQ efficacy study was nested into the trial. The study is registered under http://www.controlled-trials.com (ISRCTN 34104704. Results The intervention was shown to be feasible under program conditions and a total of 1.076 children and 999 children were evaluated at baseline and follow-up time points respectively. Self-reported CQ treatment of fever episodes at home as well as referrals to health centres increased over the study period. At follow-up, CQ was detected in the blood of high proportions of intervention and control children. Compared to baseline findings, the prevalence of anaemia (29% vs 16%, p P. falciparum parasitaemia, fever and palpable spleens was lower at follow-up but there were no differences between the intervention and control group. CQ efficacy decreased over the study period but this was not associated with the intervention. Discussion The decreasing prevalence of malaria

    In the Sourou area of Burkina Faso, parasitological and malacological surveys of urinary schistosomiasis have been carried out in the constructed sites of Guédougou, Niasan and Débé dating respectively from 1967, 1986 and 1996. The investigations covered also the traditional villages of Lanfiera, Di, Poro, Tiao and Mara situated in the middle of the hydroagricultural planning for the first, very close to the lake for the second and about twenty kilometres distant for the three last. These towns represent the main sites in the Sourou area. The results of the parasitological surveys showed that urinary schistosomiasis was present in all sites. The levels of prevalence varied considerably: 70.3% in Guiédougou, 40.8% in Niassan, 8.5% in Débè in the irrigated zone, 55.6% in Lanfiéra, 56.8% in Di, 13.2% in Poro, 83.3% in Tiao and 64.7% in Mara. Concerning the malacological investigation, two species (Bulinus senegalensis and B. truncatus) were shown to be intermediate hosts of Schistosoma haematobium. The first was endemic to the area while the second was compatible with S. haematobium from the Sourou and other zones. Compared to the results of earlier investigations, the endemic had worsened with differences according to sites. This disparity of prevalence levels which has already been observed in other hydroagricultural area results from many factors, among which the impact of irrigation activities, the aquatic biotope system (irrigation canals, natural lake, pools and temporary rivers) and the type of contact of human communities with water rank high. Schistosomiasis expansion is amplified by the intermediate host dynamics and the introduction of new schistosomes carried by the new workers arriving from all over the country. In these conditions, in order to reduce rapidly prevalence levels, preventive measures should be centred on chemotherapy for the population. The treatment should be administered during a period of weak intermediate host density and be

    Full Text Available Abstract Background Despite low endemicity, malaria remains a major health problem in urban areas where a high proportion of fevers are presumptively treated using anti-malarial drugs. Low acquired malaria immunity, behaviour of city-dwellers, access to health care and preventive interventions, and heterogenic suitability of urban ecosystems for malaria transmission contribute to the complexity of the malaria epidemiology in urban areas. Methods The study was designed to identify the determinants of malaria transmission estimated by the prevalence of anti-circumsporozoite (CSP antibodies, the prevalence and density of Plasmodium falciparum infection, and the prevalence of malarial disease in areas of Ouagadougou, Burkina-Faso. Thick blood smears, dried blood spots and clinical status have been collected from 3,354 randomly chosen children aged 6 months to 12 years using two cross-sectional surveys (during the dry and rainy seasons in eight areas from four ecological strata defined according to building density and land tenure (regular versus irregular. Demographic characteristics, socio-economic information, and sanitary and environmental data concerning the children or their households were simultaneously collected. Dependent variables were analysed using mixed multivariable models with random effects, taking into account the clustering of participants within compounds and areas. Results Overall prevalences of CSP-antibodies and P. falciparum infections were 7.7% and 16.6% during the dry season, and 12.4% and 26.1% during the rainy season, respectively, with significant differences according to ecological strata. Malaria risk was significantly higher among children who i lived in households with lower economic or education levels, iii near the hydrographic network, iv in sparsely built-up areas, v in irregularly built areas, vi who did not use a bed net, vii were sampled during the rainy season or ii had traveled outside of Ouagadougou

    Full Text Available BACKGROUND: Malariometric parameters are often primary endpoints of efficacy trials of malaria vaccine candidates. This study aims to describe the epidemiology of malaria prior to the conduct of a series of drug and vaccine trials in a rural area of Burkina Faso. METHODS: Malaria incidence was prospectively evaluated over one year follow-up among two cohorts of children aged 0-5 years living in the Saponé health district. The parents of 1089 children comprising a passive case detection cohort were encouraged to seek care from the local health clinic at any time their child felt sick. Among this cohort, 555 children were randomly selected for inclusion in an active surveillance sub-cohort evaluated for clinical malaria during twice weekly home visits. Malaria prevalence was evaluated by cross-sectional survey during the low and high transmission seasons. RESULTS: Number of episodes per child ranged from 0 to 6 per year. Cumulative incidence was 67.4% in the passive and 86.2% in the active cohort and was highest among children 0-1 years. Clinical malaria prevalence was 9.8% in the low and 13.0% in the high season (p>0.05. Median days to first malaria episode ranged from 187 (95% CI 180-193 among children 0-1 years to 228 (95% CI 212, 242 among children 4-5 years. The alternative parasite thresholds for the malaria case definition that achieved optimal sensitivity and specificity (70-80% were 3150 parasites/µl in the high and 1350 parasites/µl in the low season. CONCLUSION: Clinical malaria burden was highest among the youngest age group children, who may represent the most appropriate target population for malaria vaccine candidate development. The pyrogenic threshold of parasitaemia varied markedly by season, suggesting a value for alternative parasitaemia levels in the malaria case defintion. Regional epidemiology of malaria described, Sapone area field centers are positioned for future conduct of malaria vaccine trials.

    Assessing landscape and population's dynamics at watershed level contribute to address anthropogenic aspect of climate change issue owing to the close link between LULC and climate changes. The objective of this study is to explore the dependencies of population to land management changes in Massili basin (2612 km²) located in central Burkina Faso. A set of three satellite scenes was acquired for the years 1990 (Landsat 7 ETM), 2002 (Landsat 7 ETM+) and 2013 (Landsat 8 OLI/TIRS) from the Global Land Cover Facility's (GLCF) website. Census data were provided by the National institute of statistics and demographic (INSD). The satellites images were classified using object-oriented classification method which was supported by historic maps and field data. Those were collected in order to allow for class definition, verification and accuracy assessments. Based on the developed land use maps, change analysis was carried out using post classification comparison in GIS. Finally, derived land use changes were compared with census data in order to explore links between population dynamics and the land use changes. It was found in 1990 that Massili watershed LULC was dominated by Tree/shrub savannah (69%, 1802.28 km2 ), Farm/Fallow was representing 22%, Gallery forest (4%), Settlement (3%), Barre soil (1%), Water bodies (1%). In 2002, the major landscape was Farm (54%). Tree/Shrub savannas were reduced to 36% while the Gallery Forest was decreased to1% of the basin area. The situation has also slightly changed in 2013 with an increase of the area devoted to farm/fallow and settlement at a rate of 3% and Gallery forest has increased to 4%. The changes in land use are in agreement with a notable increase in population. The analysis of census data showed that the number of inhabitants increased from 338 inhabitants per km2 in 1990 to 1150 inhabitants per km2 in 2013. As shown by statistical analysis (Kendall correlation tau=0.9), there is a close relation between both dynamics.

  5. A guideline for sizing Photovoltaic panels across different climatic zones in Burkina Faso

    International Nuclear Information System (INIS)

    In many developing countries a long time series of solar radiation measurements are not often available. This is due to the cost, maintenance and calibration requirements of measuring devices. Consequently, the use of solar energy by Photovoltaic (PV) conversion copes with the choice and the optimization of the PV system. This work concerned the analysis of climate parameters strongly influencing the Photovoltaic (PV) systems energy production and the simulation of an ideal system based on a single PV module. Estimation and analysis of time series of climate parameters covered a set of six weather stations with respect to the three climatic zones in Burkina Faso (BF), over 38 years. The analysis showed that the solar irradiation in BF lies between 3 kWh/m2/day and 7.5 kWh/m2/day. The highest values of the solar irradiation are measured in the Northern part of the country while lowest values are measured in the Southern part. Daily mean temperature for all weather stations was greater than the Standard Test Condition (STC) temperature (25°C) over a long period of the year. Information on solar irradiation and temperature is fundamental for PV systems sizing process. For PV performance evaluation, a simulation is carried out using an ideal system composed of a single PV module from TENESOL Company. This simulation is performed for three classes of climatic conditions 'Mean situation', 'Adverse situation', and 'Beneficial situation', and evaluated for six sitesacross BF. The results revealed intra-annual and spatial variability of Maximum Power (MP). Across BF, MP varied between 60 W/day and 190 W/day in Sahelian zone, between 65 W/day and 185 W/day in soudano-sahelian zone, and between 67 W/day and 208 W/day in Soudanian zone. MP intra-annual variability is higher during the period July-August, mainly for 'Beneficial situation'. The negative effect of temperature on PV energy production is specially amplified in Sahelian zone due to its highest temperatures. This

  6. Adapting to an innovation: Solar cooking in the urban households of Ouagadougou (Burkina Faso)

    Toonen, Hilde M.

    Most households in Sub-Saharan Africa rely on wood as primary energy source. The availability of wood is decreasing and deforestation is a major ecological problem in Sub-Saharan Africa. The scarcity of wood is demanding for a sustainable solution. The sun seems to provide a good alternative. Solar energy is free, without unhealthy smoke or chances to burns. The idea of using solar energy for cooking is not new: many different techniques have already been tested. Most variants are expensive, and therefore not available for most families in Sub-Saharan Africa. A cheap solar cooking device is the CooKit, a cardboard panel cooker covered with aluminium foil. In the adaptation to the CooKit, as to all innovations, it is important that the users are convinced of the advantages. An important step in the adaptation process is learning how to use the cooking device; the best way to do this is by home practice. Monitoring and evaluating the real use is needed, for it is interesting to know if the CooKit is actually used, and also to find out how women have implemented the new technique in their kitchens. In 2005, the SUPO foundation started a project in Burkina Faso: Programme Energie Solaire Grand-Ouaga (PESGO). The aim of PESGO is to introduce the CooKit in the urban households in Ouagadougou by providing training sessions and home assistance. In this paper, a mid-term review on this small-scale cooking project is presented. The possibilities and challenges of solar cooking are outlined, taking the urban context of Ouagadougou in account. In PESGO, dependence on weather conditions is found to be one of the challenges: if sunrays are blocked by clouds or dust in the air, the cooking will be slowed down. The CooKit cannot replace firewood entirely, and a complementary element has to be found. SUPO is exploring the use of Jatropha oil as a complement to the CooKit. The Jatropha plant is drought tolerant and its fruits contain oil which can be used as fuel substitute. Further

    Full Text Available Abstract Background This methodological article is based on a health policy research project conducted in Burkina Faso (West Africa. Concept mapping (CM was used as a research method to understand the local views of equity among stakeholders, who were concerned by the health policy under consideration. While this technique has been used in North America and elsewhere, to our knowledge it has not yet been applied in Africa in any vernacular language. Its application raises many issues and certain methodological limitations. Our objective in this article is to present its use in this particular context, and to share a number of methodological observations on the subject. Methods Two CMs were done among two different groups of local stakeholders following four steps: generating ideas, structuring the ideas, computing maps using multidimensional scaling and cluster analysis methods, and interpreting maps. Fifteen nurses were invited to take part in the study, all of whom had undergone training on health policies. Of these, nine nurses (60% ultimately attended the two-day meeting, conducted in French. Of 45 members of village health committees who attended training on health policies, only eight were literate in the local language (Moore. Seven of these (88% came to the meeting. Results The local perception of equity seems close to the egalitarian model. The actors are not ready to compromise social stability and peace for the benefit of the worst-off. The discussion on the methodological limitations of CM raises the limitations of asking a single question in Moore and the challenge of translating a concept as complex as equity. While the translation of equity into Moore undoubtedly oriented the discussions toward social relations, we believe that, in the context of this study, the open-ended question concerning social justice has a threefold relevance. At the same time, those limitations were transformed into strengths. We understand that it was

    Full Text Available Background: National surveys in low-income countries increasingly rely on self-reported measures of health. The ease, speed, and economy of collecting self-reports of health make such collection attractive for rapid appraisals. However, the interpretation of these measures is complicated since different cultures understand and respond to the same question in different ways. Objective: The aim of this pilot study was to develop a culturally sensitive tool to study the self-reported health (SRH of the local adult population in Burkina Faso. Design: The study was carried out in the 2009 rainy season. The sample included 27 men and 25 women aged 18 or older who live in semi-urban Nouna, Burkina Faso. Three culturally adapted instruments were tested: a SRH question, a wooden visual analogue scale (VAS, and a drawn VAS. Respondents were asked to explain their answers to each instrument. The narratives were analyzed with the content analysis technique, and the prevalence of poor SRH was estimated from the quantitative data by stratification for respondent background variables (sex, age, literacy, education, marital status, ethnicity, chronic diseases. The correlation between the instruments was tested with Spearman's correlation test. Results: The SRH question showed a 38.5% prevalence of poor SRH and 44.2% prevalence with both VAS. The correlation between the VAS was 0.89, whereas the correlation between the VAS and the SRH question was 0.60–0.64. Nevertheless, the question used as the basis of each instrument was culturally sensitive and clear to all respondents. Analysis of the narratives shows that respondents clearly differentiated between the various health statuses. Conclusion: In this pilot, we developed and tested a new version of the SRH question that may be more culturally sensitive than its non-adapted equivalents. Additional insight into this population's understanding and reporting of health was also obtained. A larger sample is needed

    Full Text Available This study estimates the impact on Burkina Faso of eliminating tariffs on imports from the EU under EPAs, considering trade, revenue and welfare effects. At complete elimination of tariffs on all products imports from trade classification sections (TDC 01-13 from the EU. Burkina Faso is likely to experience both welfare gains and losses depending on the values of imports of each trade classification section in question. The overall welfare effect relative to GDP tends to be very small and positive, but potential tariff revenue losses are enormous even when the country has up to fifteen - twenty-five years in which to implement the tariff reductions, unless with scope for tax substitution. EPAs effects are concentrated on those product sections where trade creation outweighs trade diversion such as Animal products, Vegetable products, Animal/Veg. products, Mineral products, and Textiles products. Besides, product sections with the greatest market opportunities for EU suppliers to displace any of the other suppliers, ECOWAS and/or ROW include sections where trade diversion outweighs trade creation effects, such as prepared foodstuffs, product of chemicals, plastics, raw hides & skin, etc. The sensitive products (SPs to be excluded from tariff removal should include sections in which ECOWAS member nations are suppliers to regional importers so that excluding them as SPs would improve the welfare gain compared to estimates where tariff are removed from those products in which ECOWAS have zero potential. The results at this level of aggregation will provide useful information to the on-going negotiations between ECOWAS and the EU in determining Burkinabe's products to be exempted from tariff removal during EPAs based on the severity of the effects on varied trade classification (TDC sections, among other considerations.

    Full Text Available Background: There are more than 40 Health and Demographic Surveillance System (HDSS sites in 19 different countries. The running costs of HDSS sites are high. The financing of HDSS activities is of major importance, and adding external health surveys to the HDSS is challenging. To investigate the ways of improving data quality and collection efficiency in the Nouna HDSS in Burkina Faso, the stand-alone data collection activities of the HDSS and the Household Morbidity Survey (HMS were integrated, and the paper-based questionnaires were consolidated into a single tablet-based questionnaire, the Comprehensive Disease Assessment (CDA. Objective: The aims of this study are to estimate and compare the implementation costs of the two different survey approaches for measuring population health. Design: All financial costs of stand-alone (HDSS and HMS and integrated (CDA surveys were estimated from the perspective of the implementing agency. Fixed and variable costs of survey implementation and key cost drivers were identified. The costs per household visit were calculated for both survey approaches. Results: While fixed costs of survey implementation were similar for the two survey approaches, there were considerable variations in variable costs, resulting in an estimated annual cost saving of about US$45,000 under the integrated survey approach. This was primarily because the costs of data management for the tablet-based CDA survey were considerably lower than for the paper-based stand-alone surveys. The cost per household visit from the integrated survey approach was US$21 compared with US$25 from the stand-alone surveys for collecting the same amount of information from 10,000 HDSS households. Conclusions: The CDA tablet-based survey method appears to be feasible and efficient for collecting health and demographic data in the Nouna HDSS in rural Burkina Faso. The possibility of using the tablet-based data collection platform to improve the quality

    The rapid scale-up of human immunodeficiency virus (HIV) testing, counselling and treatment throughout sub-Saharan Africa has raised questions about how to protect patients' rights to consent, confidentiality, counselling and care in resource-constrained settings. The Multi-country African Testing and Counselling for HIV (MATCH) study investigated client and provider experiences with different modes of testing in sub-Saharan Africa. One component of that study was a survey of 275 HIV service providers in Burkina Faso, Kenya and Uganda that gathered quantifiable indicators and qualitative descriptions using a standardized instrument. This article presents provider perspectives on the challenges of obtaining consent, protecting confidentiality, providing counselling and helping clients manage disclosure. It also explores health workers' fear of infection within the workplace and their reports on discrimination against HIV clients within health facilities. HIV care providers in Burkina Faso, Kenya and Uganda experienced substantial rewards from their work, including satisfaction from saving lives and gaining professional skills. They also faced serious resource constraints, including staff shortages, high workloads, lack of supplies and inadequate infrastructure, and they expressed concerns about accidental exposure. Health workers described heavy emotional demands from observing clients suffer emotional, social and health consequences of being diagnosed with HIV, and also from difficult ethical dilemmas related to clients who do not disclose their HIV status to those around them, including partners. These findings suggest that providers of HIV testing and counselling need more resources and support, including better protections against HIV exposure in the workplace.

    Full Text Available BACKGROUND: little is known about porcine cysticercosis in Burkina Faso. We conducted a pilot study to estimate the prevalence of antigens of Taenia solium cysticercosis and to identify associated factors in pigs of three villages in Burkina Faso, selected to represent different pig management practices: one village where pigs are allowed to roam freely (Batondo, one village where pigs are penned part of the time (Pabré and one village with limited pig farming (Nyonyogo. METHODS/PRINCIPAL FINDINGS: a clustered random sampling design was used. Data on socio-demographic characteristics (source of drinking water, presence of latrines in the household, type and number of breeding animals and pig management practices were collected using a standardized questionnaire. Blood samples were collected from one pig per household to determine the presence of antigens of the larval stages of T. solium by the B158/B60 Ag-ELISA. The associations between seropositivity and socio-demographic and pig management practices were estimated using logistic regression. Proportions of 32.5% (95% CI 25.4-40.3, 39.6% (31.9-47.8, and 0% of pigs, were found positive for the presence of circulating antigens of T. solium in Batondo, Pabré, and Nyonyogo, respectively. The results of the logistic regression analyses suggested that people acquire knowledge on porcine cysticercosis following the contamination of their animals. The presence of antigens in the pigs' sera was not associated with the absence of latrines in the household, the source of drinking water or the status of infection in humans but was associated with pig rearing practices during the rainy season. CONCLUSIONS/SIGNIFICANCE: the results suggest that education of pig farmers is urgently needed to reduce the prevalence of this infection.

    Full Text Available Abstract Background Infant mortality rates (IMR remain high in many sub-Saharan African countries, especially in rural settings where access to health services may be limited. Studies in such communities can provide relevant data on the burden of and risk factors for infant death. We measured IMR and explored risk factors for infant death in a cohort of children born in Banfora Health District, a rural area in South-West Burkina Faso. Methods A prospective community-based cohort study was nested within the PROMISE-EBF trial (NCT00397150 in 24 villages of the study area. Maternal and infant baseline characteristics were collected at recruitment and after birth, respectively. Home visits were conducted at weeks 3, 6, 12, 24 and 52 after birth. Descriptive statistics were calculated using robust standard errors to account for cluster sampling. Cox multivariable regression was used to investigate potential risk factors for infant death. Results Among the 866 live born children included in the study there were 98 infant deaths, yielding an IMR of 113 per 1000 live births (95% CI: 89–143. Over 75% of infant deaths had occurred by 6 months of age and the post neonatal infant mortality rate was 67 per 1000 live births (95% CI: 51–88. Infections (35% and preterm births complications (23% were the most common probable causes of death by 6 months. Multivariable analyses identified maternal history of child death, polygyny, twin births and poor anthropometric z-scores at week-3 as factors associated with increased risk of infant death. Conclusions We observed a very high IMR in a rural area of Burkina Faso, a country where 75% of the population lives in rural settings. Community-based health interventions targeting mothers and children at high risk are urgently needed to reduce the high burden of infant deaths in these areas.

    Full Text Available Abstract Background Little is known about the reproductive health of women who survive obstetric complications in poor countries. Our aim was to determine how severe obstetric complications in Burkina Faso affect reproductive events in the first year postpartum. Methods Data were collected from a prospective cohort of women who either experienced life threatening (near-miss pregnancy-related complications or an uncomplicated childbirth, followed from the end of pregnancy to one year postpartum or post-abortum. Documented outcomes include menses resumption, sexual activity resumption, dyspareunia, uptake of contraceptives, unmet needs for contraception and women's reproductive intentions. Participants were recruited in seven hospitals between December 2004 and March 2005 in six towns in Burkina Faso. Results Reproductive events were associated with pregnancy outcome. The frequency of contraceptive use was low in all groups and the method used varied according to the presence or not of a live baby. The proportion with unmet need for contraception was high and varied according to the time since end of pregnancy. Desire for another pregnancy was highest among near-miss women with perinatal death or natural abortion. Women in the near-miss group with induced abortion, perinatal death and natural abortion had significantly higher odds of subsequent pregnancy. Unintended pregnancies were observed mainly in women in the near-miss group with live birth and the uncomplicated delivery group. Conclusions Considering the potential deleterious impact (on health and socio-economic life of new pregnancies in near-miss women, it is important to ensure family planning coverage includes those who survive a severe complication.

    Full Text Available Diversification and inter-species integration in rural livestock system in Burkina Faso. The purpose of this study was to determine the level of existing relation between several animal species bred in extensive livestock systems. Data were collected about breeding importance of cattle, sheep, goat and fowl in four villages of the central region of Burkina Faso (Namanegma, Villy-Moukouan, Luili-Nobere and Yambasse. These villages are located in the Soudano-Sahelian agroclimatic zone. Partial correlation and bivariate ordinary least square methods are computed. The results show that livestock practices are related to diversification and species integration strategies of rural households. That is, many households (16.64/ breed four species together, while 6.14/ of households possess one species. Three and two species breeders account for 14.95 and 14.36/ of households respectively. Poultry represents a driving activity in extensive livestock system. From a social welfare standpoint, fowl activity accounts for 49.42/ of households employment. Cattle breeding is the highest stage in this system and represents a kind ofsocioeconomic prestige for the breeder. The four types of livestock are correlated at different levels. Thus, high correlation degrees are noted between poultry and goat (p > 0.50. On the other hand, there is a weak relation between the remote livestock levels (e.g. poultry and cattle, p < 0.50. These results suggest that incentive policies for livestock must take into account breeders strategies. To promote poultry production can create track down effect on the entire livestock system.

    Full Text Available Abstract Until 2010, Burkina Faso was an exception to the international trend of abolishing user fees for antiretroviral treatment (ART. Patients were still expected to pay 1,500F CFA (2 Euros per month for ART. Nevertheless, many non-governmental organizations (NGOs exempted patients from payment. The objective of this study was to investigate how NGOs selected the beneficiaries of payment exemptions for government-provided ART and rationed out complementary medical and psychosocial services. For this qualitative study, we conducted 13 individual interviews and three focus group discussions (n = 13 persons with program staff in nine NGOs (4,000 patients, two NGO coordinating structures and one national program. These encounters were recorded and transcribed, and their content was thematically analyzed. The results were presented to the NGOs for feedback. Results indicate that there are no concrete guidelines for identifying patients warranting payment exemptions. Formerly, ART was scarce in Burkina Faso and the primary criterion for treatment selection was clinical. Our results suggest that this scarcity, mediated by an approach we call sociotherapeutic rationality (i.e. maximization of clinical success, may have led to inequities in the provision of free ART. This approach may be detrimental to assuring equity since the most impoverished lack resources to pay for services that maximize clinical success (e.g. viral load that would increase their chances of being selected for treatment. However, once selected into treatment, attempts were made to ration-out complementary services more equitably. This study demonstrates the risks entailed by medication scarcity, which presents NGOs and health professionals with impossible choices that run counter to the philosophy of equity in access to treatment. Amid growing concerns of an international funding retreat for ART, it is important to learn from the past in order to better manage the potentially

    Full Text Available Abstract Background Predation of aquatic immature stages has been identified as a major evolutionary force driving habitat segregation and niche partitioning in the malaria mosquito Anopheles gambiae sensu stricto in the humid savannahs of Burkina Faso, West Africa. Here, we explored behavioural responses to the presence of a predator in wild populations of the M and S molecular forms of An. gambiae that typically breed in permanent (e.g., rice field paddies and temporary (e.g., road ruts water collections. Methods Larvae used in these experiments were obtained from eggs laid by wild female An. gambiae collected from two localities in south-western Burkina Faso during the 2008 rainy season. Single larvae were observed in an experimental arena, and behavioural traits were recorded and quantified a in the absence of a predator and b in the presence of a widespread mosquito predator, the backswimmer Anisops jaczewskii. Differences in the proportion of time allocated to each behaviour were assessed using Principal Component Analysis and Multivariate Analysis of Variance. Results The behaviour of M and S form larvae was found to differ significantly; although both forms mainly foraged at the water surface, spending 60-90% of their time filtering water at the surface or along the wall of the container, M form larvae spent on average significantly more time browsing at the bottom of the container than S form larvae (4.5 vs. 1.3% of their overall time, respectively; P P P P Conclusions Behavioural differences between larvae of the M and S form of An. gambiae in response to an acute predation risk is likely to be a reflection of different trade-offs between foraging and predator vigilance that might be of adaptive value in contrasting aquatic ecosystems. Future studies should explore the relevance of these findings under the wide range of natural settings where both forms co-exist in Africa.

    In Burkina-Faso, urban vegetable agriculture is often characterized by urban solid waste fertilizer inputs containing heavy metals such as Cu and Cd. Thus, the relevance of surrounding urban vegetable plots with vetiver hedges to reduce environmental pollution by Cu and Cd was investigated by adsorption studies and pot experiments. Vetiver biomass, its metal contents and, its total and MgCl2 extractable soil metals were monitored over 6months in the presence of a mixture of metal at two concentrations: 2-10 and 100-500mgkg(-1), for Cd and Cu, respectively. The Freundlich adsorption coefficient (Kf) values increased after vetiver growth and were significantly higher for vertisol than for lixisol. After 6months, the vetiver that was grown on lixisol accumulated more metal, increasing up to 4635mgkg(-1) for Cu and to 21.8mgkg(-1) for Cd, than did the vetiver that was grown on vertisol, increasing up to 1534mgkg(-1) for Cu and to 7.2mgkg(-1) for Cd. The metal bioconcentration factor, which was significantly higher for Cd, increased with the applied concentration and ranged from 1.6 to 14 for Cu and from 2.3 to 22 for Cd. Additionally, the translocation factors were higher for Cd (0.38-7.3) than for Cu (0.07-2.6), and the translocation was easiest from lixisol than from vertisol. Thus our results demonstrate the ability of vetiver for Cu and Cd phytoremediation in Burkina Faso soils. Nevertheless, these results should be confirmed across the field to advocate the establishment of vetiver hedges. PMID:25065788

    The policy of institutional delivery has been the cornerstone of actions aimed at monitoring and achieving MDG 5. Efforts to increase institutional births have been implemented worldwide within different cultural and health systems settings. This paper explores how communities in rural Burkina Faso perceive the promotion and delivery of facility pregnancy and birth care, and how this promotion influences health-seeking behaviour. A qualitative study was conducted in South-Western Burkina Faso between September 2011 and January 2012. A total of 21 in-depth interviews and 8 focus group discussions with women who had given birth recently and community members were conducted. The data were analyzed using qualitative content analysis and interpreted through Merton’s concept of unintended consequences of purposive social action. The study found that community members experienced a strong pressure to give birth in a health facility and perceived health workers to define institutional birth as the only acceptable option. Women and their families experienced verbal, economic and administrative sanctions if they did not attend services and adhered to health worker recommendations, and reported that they felt incapable of questioning health workers’ knowledge and practices. Women who for social and economic reasons had limited access to health facilities found that the sanctions came with increased cost for health services, led to social stigma and acted as additional barriers to seek skilled care at birth. The study demonstrates how the global and national policy of skilled pregnancy and birth care can occur in unintentional ways in local settings. The promotion of institutional care during pregnancy and at birth in the study area compromised health system trust and equal access to care. The pressure to use facility care and the sanctions experienced by women not complying may further marginalize women with poor access to facility care and contribute to worsened health

    We investigated the evolution of Pfcrt K76T mutation five years after the withdrawal of chloroquine in Burkina Faso. A total of 675 clinical isolates collected from October 2010 to September 2012 were successfully genotyped. Single nucleotide polymorphism in Pfcrt (codon 76) gene was analyzed. The prevalence of resistant Pfcrt 76T allele was 20.55%. There was a progressive decrease of the proportion of mutant type pfcrt T76 from 2010 to 2012 (X2=5.508 p=0.0189). Our results suggest a progressive return of the wild type Pfcrt K76 in Burkina Faso but the prevalence of the mutants Pfcrt T76 still remains high. PMID:26516402

    Full Text Available Abstract Background Agricultural biotechnology public-private partnerships (PPPs have been recognized as having great potential in improving agricultural productivity and increasing food production in sub-Saharan Africa. However, there is much public skepticism about the use of GM (genetically modified crops and suspicion about private sector involvement in agbiotech projects. This case study sought to understand the role of trust in the Bacillus thuringiensis (Bt cotton in Burkina Faso project by exploring practices and challenges associated with trust-building, and determining what makes these practices effective from the perspective of multiple stakeholders. Methods We conducted semi-structured, face-to-face interviews to obtain stakeholders’ understanding of trust in general as well as in the context of agbiotech PPPs. Relevant documents and articles were analyzed to generate descriptions of how trust was operationalized in this evolving agbiotech PPP. Data was analyzed based on emergent themes to create a comprehensive narrative on how trust is understood and built among the partners and with the community. Results We derived four key lessons from our findings. First, strong collaboration between research, industry and farmers greatly contributes to both the success of, and fostering of trust in, the partnership. Second, this case study also revealed the important, though often unrecognized, role of researchers as players in the communication strategy of the project. Third, effective and comprehensive communication takes into account issues such as illiteracy and diversity. Fourth, follow-up at the field level and the need for a multifaceted communications strategy is important for helping push the project forward. Conclusions Burkina Faso’s well-established and effective cotton selling system laid the foundation for the implementation of the Bt cotton project – particularly, the strong dialogue and the receptivity to collaboration

  1. Irradiated male tsetse from a 40-year-old colony are still competitive in a Riparian forest in Burkina Faso.

    Directory of Open Access Journals (Sweden)

    Adama Sow

    Full Text Available BACKGROUND: Tsetse flies are the cyclical vectors of African trypanosomosis that constitute a major constraint to development in Africa. Their control is an important component of the integrated management of these diseases, and among the techniques available, the sterile insect technique (SIT is the sole that is efficient at low densities. The government of Burkina Faso has embarked on a tsetse eradication programme in the framework of the PATTEC, where SIT is an important component. The project plans to use flies from a Glossina palpalis gambiensis colony that has been maintained for about 40 years at the Centre International de Recherche-Développement sur l'Elevage en zone Subhumide (CIRDES. It was thus necessary to test the competitiveness of the sterile males originating from this colony. METHODOLOGY/PRINCIPAL FINDINGS: During the period January-February 2010, 16,000 sterile male G. p. gambiensis were released along a tributary of the Mouhoun river. The study revealed that with a mean sterile to wild male ratio of 1.16 (s.d. 0.38, the abortion rate of the wild female flies was significantly higher than before (p = 0.026 and after (p = 0.019 the release period. The estimated competitiveness of the sterile males (Fried index was 0.07 (s.d. 0.02, indicating that a sterile to wild male ratio of 14.4 would be necessary to obtain nearly complete induced sterility in the female population. The aggregation patterns of sterile and wild male flies were similar. The survival rate of the released sterile male flies was similar to that observed in 1983-1985 for the same colony. CONCLUSIONS/SIGNIFICANCE: We conclude that gamma sterilised male G. p. gambiensis derived from the CIRDES colony have a competitiveness that is comparable to their competitiveness obtained 35 years ago and can still be used for an area-wide integrated pest management campaign with a sterile insect component in Burkina Faso.

  2. Report on the Implementation of the Code and the Guidance in Burkina Faso: Experiences and Lessons Learned

    International Nuclear Information System (INIS)

    Burkina Faso started the implementation of the code of conduct since 2008 as a member state of the International Atomic Energy Agency (IAEA). The process went through several steps and actions. The first step was the implementation of a regulatory infrastructure with the development of legislation and regulation framework and the establishment of a regulatory body (National Authority for Radiation protection and Nuclear Safety). The key legislation is the law n°032-2012/AN on nuclear safety and safeguards. Then, the country undertook actions for the enforcement of the regulations through licensing and inspections regime. This leads to the recovering of orphan sources and the establishment of a national register of radioactive sources using RAIS software. In 2009 and 2010, the regulatory body proceeded to a wide spread inventory of radioactive sources and search of orphan sources in the country covering the thirteen regions according to the administrative division. The registered sources belong mainly to the categories III and IV. There is a low quantity of categories I and II sources. As Burkina Faso has no facility for disused sources and waste management, a contract of return is requested for their importation during the licensing process. The objective is to set a good management of the sources and assure their security. Some sources imported many years ago have no more suppliers and no return contract. An action is currently running for the repatriation of some of them with the support of IAEA. In supporting the government effort for safety and security of sources, an integrated Nuclear Security Plan has been developed by an INSERV mission taking account the radioactive material. The good implementation of these activities and the principles of the code needs a well trained staff. ARSN developed a program of training for its regulatory staff and make it participate to IAEA trainings. Our success stories are likely the well drafted law on nuclear safety and

    In Burkina Faso where cooking with biomass is very common, little information exists regarding kitchen characteristics and their impact on air pollutant levels. The measurement of air pollutants such as respirable particulate matter (PM10), an important component of biomass smoke that has been linked to adverse health outcomes, can also pose challenges in terms of cost and the type of equipment needed. Carbon monoxide could potentially be a more economical and simpler measure of air pollution. The focus of this study was to first assess the association of kitchen characteristics with measured PM10 and CO levels and second, the relationship of PM10 with CO concentrations, across these different kitchen characteristics in households in Nouna, Burkina Faso. Twenty-four-hour concentrations of PM10 (area) were measured with portable monitors and CO (area and personal) estimated using color dosimeter tubes. Data on kitchen characteristics were collected through surveys. Most households used both wood and charcoal burned in three-stone and charcoal stoves. Mean outdoor kitchen PM10 levels were relatively high (774 μg/m(3), 95 % CI 329-1,218 μg/m(3)), but lower than indoor concentrations (Satterthwaite t value, -6.14; p kitchens were negatively associated with PM10 (OR = 0.06, 95 % CI 0.02-0.16, p value kitchens (Spearman's r = 0.82, p < 0.0001), indoor stove use (Spearman's r = 0.82, p < 0.0001), and the presence of a smoker in the household (Spearman's r = 0.83, p < 0.0001). Weak correlations between area PM10 and personal CO levels were observed with three-stone (Spearman's r = 0.23, p = 0.008) and improved stoves (Spearman's r = 0.34, p = 0.003). This indicates that the extensive use of biomass fuels and multiple stove types for cooking still produce relatively high levels of exposure, even outdoors, suggesting that both fuel subsidies and stove improvement programs are likely necessary to address this problem.

    Full Text Available Abstract Background To bring down its high maternal mortality ratio, Burkina Faso adopted a national health policy in 2007 that designed to boost the assisted delivery rate and improving quality of emergency obstetrical and neonatal care. The cost of transportation from health centres to district hospitals is paid by the policy. The worst-off are exempted from all fees. Methods The objectives of this paper are to analyze perceptions of this policy by health workers, assess how this health policy was implemented at the district level, identify difficulties faced during implementation, and highlight interactional factors that have an influence on the implementation process. A multiple site case study was conducted at 6 health centres in the district of Djibo in Burkina Faso. The following sources of data were used: 1 district documents (n = 23; 2 key interviews with district health managers (n = 10, health workers (n = 16, traditional birth attendants (n = 7, and community management committees (n = 11; 3 non-participant observations in health centres; 4 focus groups in communities (n = 62; 5 a feedback session on the findings with 20 health staff members. Results All the activities were implemented as planned except for completely subsidizing the worst-off, and some activities such as surveys for patients and the quality assurance service team aiming to improve quality of care. District health managers and health workers perceived difficulties in implementing this policy because of the lack of clarity on some topics in the guidelines. Entering the data into an electronic database and the long delay in reimbursing transportation costs were the principal challenges perceived by implementers. Interactional factors such as relations between providers and patients and between health workers and communities were raised. These factors have an influence on the implementation process. Strained relations between the groups involved

    Local knowledge could form an effective channel and base through which climate change adaptation and mitigation can be realized. This paper uses the context of savannas ecosystem services in Burkina Faso to examine local knowledge and perspectives on the changing trends in vulnerability and adaptation to climate change. The survey targeted farmers, traditional authorities and administrators at the local government level. Semi-structured questionnaires were employed for one-on-one interviews and focused group discussions for data collection. Descriptive statistics and explanatory factor analysis were used to analyze the collected data. A total of 230 farmers, 6 traditional authorities and 5 administrators belonging to 32 villages were interviewed. Most of local people (95.1-96.7%) believe that climate change is occurring, and cited general increases in average temperatures, fluctuating rainfall regimes and extended drought periods as some of their observations. They explain the increasing changes and vulnerability of savannas ecosystems through the longer time spent and distance covered to collect medicinal plants and forest food; decreasing productivity and availability of fodder, fuel wood, forest food and medicinal plant, changing uses of forest food and medicinal plant species. The views of farmers were generally shared by the traditional authorities and administrators. Adaptation actions employed by local communities are tree planting, protection of forestry resources, migration, awareness raising, conservation of soil and water resources.

    Despite a considerable knowledge of the significant role of termites in the global methane budget, very little is known about their contribution to the global nitrous oxide (N2O) budget. Release of N2O from termite (Cubitermes fungifaber) mounds was measured at a natural savanna site in the southwest of Burkina Faso from May to September 2006. Termite N2O emissions were around 20 μg N2O-N m-2 h-1 at the end of the dry season, and up to two orders of magnitude higher than N2O emissions from the surrounding termite-free soil after the onset of the rainy season. The average N2O emission rate from termite mounds during the observation period was 204 μg N2O-N m-2 h-1, and termite mounds contributed 3.0% to total N2O emissions from this savanna ecosystem. However, in other tropical terrestrial ecosystems with other termite species and/or higher termite density this share might be significantly higher.

    Essential oils have a significant role in the society where they are variously used in fields such as medicine, pharmacy, cosmetics, chemical and food-processing industries. This justifies interest which they cause and thus systematic studies are undertaken on aromatic species, allowing without any doubt their use advisedly. This study concerns the characterization of the essential oil of Cymbopogon schoenanthus of Burkina Faso, extracted by drive with the water vapor in a distillation operation. The analysis of the chemical composition is carried out by Gas Chromatography. It shows that the 16 made up ones identified account for 65. 2% of the essential oil composition. These compounds belong to the two classes regularly met in essential oils: the mono ones and sesquiterpenes. However, proportion of monoterpenes (53. 2%) is higher than that of sesquiterpenes (12%). Among the identified compounds two monoterpenes (the piperitone and δ-2-carene) remain the principal components in the essential oil. Then the authors determine the density d = 0.9057 by double weighing, the optical activity α = +28.175 by polarimetry and the refractive index n = 1.465 by an interferometric method which they describe. Cymbopogon schoenanthus is an aromatic plant of the family of Poaceae very often used in traditional pharmacopoeia for internal as well as external treatments.

  9. Competitiveness Level of Photovoltaic Solar Systems in Ouagadougou (Burkina Faso: Study Based on the Domestic Electric Meters Calibration

    Full Text Available The mean cost price of electricity in Burkina Faso at the end of the last quarter of 2012 was 158 FCFA/kWh for a country where more than 46% of the population lives below the national poverty threshold. To look for solution to that problem, the resort to photovoltaic solar energy is justified for that country. The purpose of this study is to promote the integration of both technical and economical surveys in solar energy preliminary projects in Ouagadougou. To reach that, investigations were carried out in some households and attention was paid from the calibration of the domestic electric meters. Energy demands collected within each household allow us to design a corresponding solar kit through optimization rules. An estimate was edited and financial viability study for each household was also carried out thereafter. In this study, only households using the national electricity network calibration meter on their disadvantage favorably answered to all financial indicators and appear as the only one that could profit from such project. This work is helpful to note that photovoltaic solar energy still stays at a primitive level of competitiveness compared to conventional energy resources for small systems in Ouagadougou.

    In West Africa, M and S molecular forms of Anopheles gambiae sensu stricto (Diptera: Culicidae) Giles, frequently occur together, although with different population bionomics. The S form typically breeds in rain-dependant water collections and is present during the rainy season only whereas the M form can thrive all year long in areas with permanent breeding opportunities. In the present study, we explored physiological and developmental trade-offs at play in laboratory colonies and field populations of the M and S forms that originated from an area of sympatry in Burkina Faso, where M and S larvae exhibit such habitat segregation. In the laboratory, larvae of the M form developed slower than the S form (mean values 9.51 and 8.85 days, respectively, Wilcoxon's test, P < 0.001). Although wing length and dry weight at emergence showed large variations, M females were on average 8% heavier than S females of similar wing length. Higher nutritional reserves (proteins and lipids) in teneral adults explained part of this weight difference, reflecting a better ability of the M form to garner resources at the larval stage. Furthermore, a higher rate of ovarian maturation was observed in the M form after a single bloodmeal. The relevance of these findings for parasite transmission is discussed. PMID:22681446

    Water scarcity constrains the livelihoods of millions of people in tropical drylands. Tree planting in these environments is generally discouraged due to the large water consumption by trees, but this view may neglect their potential positive impacts on water availability. The effect of trees on soil hydraulic properties linked to groundwater recharge is poorly understood. In this study, we performed 18 rainfall simulations and tracer experiments in an agroforestry parkland in Burkina Faso to investigate the effect of trees and associated termite mounds on soil infiltrability and preferential flow. The sampling points were distributed in transects each consisting of three positions: (i) under a single tree, (ii) in the middle of an open area, and (iii) under a tree associated with a termite mound. The degree of preferential flow was quantified through parameters based on the dye infiltration patterns, which were analyzed using image analysis of photographs. Our results show that the degree of preferential flow was highest under trees associated with termite mounds, intermediate under single trees, and minimal in the open areas. Tree density also had an influence on the degree of preferential flow, with small open areas having more preferential flow than large ones. Soil infiltrability was higher under single trees than in the open areas or under trees associated with a termite mound. The findings from this study demonstrate that trees have a positive impact on soil hydraulic properties influencing groundwater recharge, and thus such effects must be considered when evaluating the impact of trees on water resources in drylands.

    Although the 2008 food price crisis presumably plunged millions of households into poverty and food insecurity, the real impact of the crisis has rarely been documented using field data. Our objective was to assess the consequences of this crisis for household food insecurity and dietary diversity in urban Burkina Faso. Two cross-sectional surveys were conducted among randomly selected households in Ouagadougou in July 2007 (n = 3017) and July 2008 (n = 3002). At each round, food insecurity assessed by the Household Food Insecurity Access Scale (HFIAS), the Dietary Diversity Score of an index-member of the household (IDDS = number of food groups consumed in the last 24 h), and food expenditure were collected. Food prices of the 17 most frequently consumed food items were recorded throughout the study area. Food prices at local markets increased considerably between 2007 and 2008, especially those of fish (113%), cereals (53%), and vegetable oil (44%), increasing the household monthly food expenditure by 18%. Thirty-three percent of households were food secure in 2007 and 22% in 2008 (P = 0.02). Individuals consumed fewer fruits and vegetables, dairy products, and meat/poultry in 2008 than in 2007 (mean IDDS = 5.7 ± 1.7 food groups in 2007 vs. 5.2 ± 1.5 in 2008; P crisis. PMID:22833656

    Global advocacy campaigns increasingly highlight the negative impact of reproductive morbidity on economic productivity and development in order to justify donor investment in maternal health. Anthropological approaches nuance such narrow economic estimations of reproductive health. Drawing on ethnographic fieldwork from Burkina Faso in West Africa, this paper analyses the dynamic, and sometimes contradictory, relationship between women's work and reproductive health in impoverished communities. Specifically, it examines the consequences of life-threatening 'near-miss' obstetric complications for women's work across domestic, agricultural and economic spheres over a four-year period. Such events provide a window onto the diverse ways in which production and reproduction are intimately linked within women's everyday lives. Reproduction and production entail sources of potential empowerment and enhancement, as well as potential threats, to health and well-being. In the aftermath of 'near-miss' events, the realms of reproduction and production sometimes jeopardise each other and at other times reinforce each other, while strength in one domain can compensate for weakness in the other. Women's experiences thus reveal how 'production' and 'reproduction' are mutually constituted, challenging the purely instrumental accounts of pregnancy-related 'productivity loss' that dominate current global health discourse.

    Analysis of fifty sorghum [Sorghum bicolor (L.) Moench] varieties used in Burkina Faso showed that they have different contents of phenolic compounds, peroxidase (POX), and polyphenol oxidase (PPO). Most of the varieties (82%) had a tannin content less than 0.25% (w/w). POX specific activity was higher than the monophenolase and o-diphenolase specific activities of PPO. For POX, there was a diversity of isoforms among varieties. No clear correlation could be made between the quantitative composition of the grain in phenolics, PPO, and POX, and resistance of plant to pathogens. In general, varieties good for a thick porridge preparation ("tô") had low phenolic compounds content and a medium POX activity. From the red varieties, those used for local beer ("dolo") had a high content in phenolic compounds and PPO, and a low POX activity. The variety considered good for couscous had a low POX content. The characteristics might be useful as selection markers for breeding for specific applications. PMID:12059160

    β-lactamase production ways and inhibition patterns were investigated in cell suspensions of clinical isolates. The purpose of this research was prior to investigate the different β-lactamase molecular classes occurring in Burkina Faso owing to the local practice of β-lactam antibiotics. The use of specific inhibitors enabled to draw up an inhibition profile and consequently to assign an enzyme to accurate molecular class of β-lactamase. At the same time, β-lactamase expression ways were explored and correlated to the inhibition profiles. The current results pointed out two main groups of organisms. The first group of isolates secretes β-lactamases mainly by inducible way. Interestingly this bacterial group carries molecular class C of β-lactamase. The second group of isolates uses partial inducible and partial constitutive way for enzyme expression. These bacteria mostly carry molecular class A of β-lactamases. The sole exception encountered during these investigations is an organism, expressing exclusively by the constitutive way an enzyme that is found to belong to molecular class B of β-lactamases.

    Christopher M Jones

    Full Text Available In the city of Bobo-Dioulasso in Burkina Faso, Anopheles arabiensis has superseded Anopheles gambiae s.s. as the major malaria vector and the larvae are found in highly polluted habitats normally considered unsuitable for Anopheles mosquitoes. Here we show that An. gambiae s.l. adults emerging from a highly polluted site in the city centre (Dioulassoba have a high prevalence of DDT resistance (percentage mortality after exposure to diagnostic dose=65.8% in the dry season and 70.4% in the rainy season, respectively. An investigation into the mechanisms responsible found an unexpectedly high frequency of the 1014S kdr mutation (allele frequency=0.4, which is found at very low frequencies in An. arabiensis in the surrounding rural areas, and an increase in transcript levels of several detoxification genes, notably from the glutathione transferase and cytochrome P450 gene families. A number of ABC transporter genes were also expressed at elevated levels in the DDT resistant An. arabiensis. Unplanned urbanisation provides numerous breeding grounds for mosquitoes. The finding that Anopheles mosquitoes adapted to these urban breeding sites have a high prevalence of insecticide resistance has important implications for our understanding of the selective forces responsible for the rapid spread of insecticide resistant populations of malaria vectors in Africa.

    Full Text Available The NGO Terre Verte pursues the realisation of bocage perimeters (wégoubri in the mooré language in Burkina Faso. They are an innovative concept of rural development that has been established in the 1990s in the experimental farm of Guiè and is now adopted in other experimental farms in Burkina Faso. The deterioration of the rural landscape in the Sahel region has worsened in the last decades, endangering local populations. The creation of bocage perimeters in this rural landscape is a way to remediate problems linked to overly extensive agriculture. Through a holistic approach to the problem, the experimental farm of Guiè has been able to integrate environmental preservation into the Sahel agriculture thanks to three axes of intervention: applied research, education and direct help to the peasants. An experimental farm relies on five technical teams, each supervised by a coordinator.The concept is based on the creation of bocage perimeters in a mixed propriety regime, comprising individually owned plots and common grounds, managed by an association of beneficiaries. The result is a restored environment, in which agriculture is no longer tantamount to erosion and livestock farming to overgrazing, where trees and bushes are harmoniously integrated into the environment.The increase in agricultural yields observed after a few years of soil restoration leads to the conclusion that those projects will be economically viable. A system of credits for farmers could allow the implementation of such a system, which represents the only solution for the millions of hectares of degraded soil in the Sahel region.L’ONG Terre Verte réalise au Burkina Faso des périmètres bocagers (wégoubri en langue mooré.

    Full Text Available Lineage organization, motor of the cotton farming growth? The Bwa of Burkina Faso. In Burkina Faso, country producing cotton, the social situations, the results and performances of the cotton farmers are various. The present research focus on the cotton area of Houndé in the Bwaba region. It is one of the most productive areas of the country where the growth of cotton has been a success story. The reasons for this success are analysed in the village called Dossi, focusing on the links between the cotton growth and the social organization, particularly the lineage one. The national cotton production is based on the Cotton Groups Farmers. Dossi's analysis shows that two kinds of relationships organize Cotton Groups Farmers: relationships between founding lineages and hosted families on one hand, relationships between elders and subjected members of the lineages on the other hand. The traditional lineage organization, adapting and rationalizing cotton production's management, became one of the key to cotton's success, in the area of Houndé. The cotton business could grow because it did not challenge the traditionnal organization. Nevertheless, economic and social inequalities increased with the development of cotton production in the villages. Today, belonging to a founding lineage is decisive in the cotton production context. However, social transformations are in progress inside founding lineages. Indeed some cadets manage big farms whereas it would have been impossible fifty years ago. Farm advice should be given according to the lineage position of each farmer. It would guarantee for all farmers the improvement of their social and economic condition. Today, it is necessary to strengthen rural cotton farming communities because they are weakened by the privatization of a part of cotton industry in Burkina Faso.

Methods The frequency of peripheral blood CD4+ lymphocytes responding to Plasmodium falciparum merozoite surface protein 1 (PfMSP-1 by production of interferon-gamma (IFN-γ, interleukin-2 (IL-2 or tumor necrosis factor-alpha (TNF-α was determined using a commercially available flow cytometric activation assay (Fastlmmune in 17 healthy adults in Nouna, Burkina Faso. T-cell activation and maturation in peripheral blood of healthy adults in Burkina Faso (n = 40 and Germany (n = 20 were compared using immunophenotyping and three-colour flow cytometry. Results Significant numbers of PfMSV-1 -specific CD4+ lymphocytes producing IFN-γ, IL-2 and/or TNF-α were detected in 14 healthy adults in Nouna. Cytokine profiles showed predominant production of IFN-γ and TNF-α. Compared to Germans, Burkinabé showed markedly lower proportions of CCR7+ CD45RA+ naïve CD4+ cells and slightly higher frequencies of CD95+ CD4+ T-cells and of CD38+ CD8+ T-cells. The median antibody-binding capacity of CD95dim CD4+ T-cells in Burkinabé was more than twice the value observed in Germans (263 vs. 108 binding sites per cell, p Conclusions We hypothesize that an IFN-γ-induced increase in the expression level of CD95 on CD4+ lymphocytes may lower the activation threshold of resting naïve CD4+ T-cells in healthy adults living in Burkina Faso. Bystander activation of these cells deserves further study as a molecular mechanism linking strong IFN-γ responses against Plasmodium falciparum to decreased susceptibility to parasitemia observed in specific ethnic groups in West Africa.

    Background Vertical human immunodeficiency virus (HIV) transmission is a public health problem in Burkina Faso. The main objective of this study on the prevention of mother-to-child HIV-1 transmission was to determine the residual risk of HIV transmission in infants born to mothers receiving highly active antiretroviral therapy (HAART). Moreover, we detect HIV antiretroviral (ARV) drug resistance among mother–infant pairs and identify subtypes and circulating recombinant forms (CRF) in Burkina Faso. Design In this study, 3,215 samples of pregnant women were analyzed for HIV using rapid tests. Vertical transmission was estimated by polymerase chain reaction in 6-month-old infants born to women who tested HIV positive. HIV-1 resistance to ARV, subtypes, and CRFs was determined through ViroSeq kit using the ABI PRISM 3,130 sequencer. Results In this study, 12.26% (394/3,215) of the pregnant women were diagnosed HIV positive. There was 0.52% (2/388) overall vertical transmission of HIV, with rates of 1.75% (2/114) among mothers under prophylaxis and 0.00% (0/274) for those under HAART. Genetic mutations were also isolated that induce resistance to ARV such as M184V, Y115F, K103N, Y181C, V179E, and G190A. There were subtypes and CRF of HIV-1 present, the most common being: CRF06_CPX (58.8%), CRF02_AG (35.3%), and subtype G (5.9%). Conclusions ARV drugs reduce the residual rate of HIV vertical transmission. However, the virus has developed resistance to ARV, which could limit future therapeutic options when treatment is needed. Resistance to ARV therefore requires a permanent interaction between researchers, physicians, and pharmacists, to strengthen the network of monitoring and surveillance of drug resistance in Burkina Faso.

Results: In this study, 12.26% (394/3,215 of the pregnant women were diagnosed HIV positive. There was 0.52% (2/388 overall vertical transmission of HIV, with rates of 1.75% (2/114 among mothers under prophylaxis and 0.00% (0/274 for those under HAART. Genetic mutations were also isolated that induce resistance to ARV such as M184V, Y115F, K103N, Y181C, V179E, and G190A. There were subtypes and CRF of HIV-1 present, the most common being: CRF06_CPX (58.8%, CRF02_AG (35.3%, and subtype G (5.9%. Conclusions: ARV drugs reduce the residual rate of HIV vertical transmission. However, the virus has developed resistance to ARV, which could limit future therapeutic options when treatment is needed. Resistance to ARV therefore requires a permanent interaction between researchers, physicians, and pharmacists, to strengthen the network of monitoring and surveillance of drug resistance in Burkina Faso.

    Au Burkina Faso, l’avortement n’est autorisé que pour sauver la vie et protéger la santé de la femme enceinte, et dans les cas de viol, d’inceste ou de graves malformations foetales. Par conséquent, la grande majorité des femmes qui mettent fin à leur grossesse le font dans le secret, par peur des poursuites, et pour éviter la stigmatisation sociale qui entoure la pratique. C’est pourquoi la plupart des avortements clandestins se produisent dans des conditions à risque, qui mettent en danger ...

    Abstract Background User fees were generalized in Burkina Faso in the 1990 s. At the time of their implementation, it was envisioned that measures would be instituted to exempt the poor from paying these fees. However, in practice, the identification of indigents is ineffective, and so they do not have access to care. Thus, a community-based process for selecting indigents for user fees exemption was tested in a district. In each of the 124 villages in the catchment areas of ten health centre...

    Full Text Available Chez les Musulmans du Burkina Faso, les mariages sont célébrés selon deux modes différents: d’une part, on trouve le mariage « traditionnel » qui s’accompagne d’une cérémonie religieuse et d’autre part, il y a le mariage “civil”, qui est marqué par une cérémonie officielle ayant lieu à la mairie. Les contrastes existants entre ces deux fêtes se révèlent notamment à travers les repas servis à cette occasion. La fête traditionnelle offre des plats et des boissons considérés comme « africains », tandis que le repas servi lors de la fête civile se compose essentiellement de tubabu dumuni ou « nourriture des Blancs ». La manière de manger amplifie également la distinction observée entre les deux fêtes: lors du repas traditionnel, les gens mangent dans les mêmes plats et avec la main, alors qu’à l’occasion de la cérémonie civile, ils utilisent assiettes, fourchettes et couteaux. A travers l’analyse de ces deux formes de cérémonies comme de leurs différences, cet article s'intéresse au discours très présent sur l’opposition entre « traditionnel » et « moderne » au Burkina Faso urbain.Muslims of Burkina Faso celebrate weddings in two distinct ways; a “traditional” celebration accompanies the religious ceremony, while a “civil” wedding party marks the official marriage which takes place at the town hall. The foods served are important markers of the contrasts between these two occasions. While so-called “African” food and drink is served at the traditional ceremony, the civil ceremony is marked by the serving of tubabu dumuni or “white man’s food”. Another distinction is the manner of eating. At the traditional meal guests eat from shared bowls, using their hands, while at the “civil” celebration the food is served on plates and is meant to be eaten with cutlery. Drawing on these two ceremonial forms and the marked distinctions between them, this paper

    Full Text Available Abstract Background In 2006, the Parliament of Burkina Faso passed a policy to reduce the direct costs of obstetric services and neonatal care in the country’s health centres, aiming to lower the country’s high national maternal mortality and morbidity rates. Implementation was via a “partial exemption” covering 80% of the costs. In 2008 the German NGO HELP launched a pilot project in two health districts to eliminate the remaining 20% of user fees. Regardless of any exemptions, women giving birth in Burkina Faso’s health centres face additional expenses that often represent an additional barrier to accessing health services. We compared the total cost of giving birth in health centres offering partial exemption versus those with full exemption to assess the impact on additional out-of-pocket fees. Methods A case–control study was performed to compare medical expenses. Case subjects were women who gave birth in 12 health centres located in the Dori and Sebba districts, where HELP provided full fee exemption for obstetric services and neonatal care. Controls were from six health centres in the neighbouring Djibo district where a partial fee exemption was in place. A random sample of approximately 50 women per health centre was selected for a total of 870 women. Results There was an implementation gap regarding the full exemption for obstetric services and neonatal care. Only 1.1% of the sample from Sebba but 17.5% of the group from Dori had excessive spending on birth related costs, indicating that women who delivered in Sebba were much less exposed to excessive medical expenses than women from Dori. Additional out-of-pocket fees in the full exemption health districts took into account household ability to pay, with poorer women generally paying less. Conclusions We found that the elimination of fees for facility-based births benefits especially the poorest households. The existence of excessive spending related to direct costs of

    ABSTRACT Objective: To investigate trends in HIV prevalence and changes in reported sexual behaviors between 1998 and 2014 in Burkina Faso. Methods: We obtained data on HIV prevalence from antenatal care (ANC) surveillance sites (N = 9) that were consistently included in surveillance between 1998 and 2014. We also analyzed data on HIV prevalence and reported sex behaviors from 3 population-based surveys from the Demographic and Health Surveys (DHS), conducted in 1998–99, 2003, and 2010. Sex behavior indicators comprised never-married youth who have never had sex; sex with more than 1 partner; sex with a nonmarital, non-cohabiting partner; condom use at last sex with a nonmarital, non-cohabiting partner; and sex before age 15. We calculated survey-specific HIV prevalence with 95% confidence intervals (CIs) and used the chi-square test or chi-square test for trend to compare HIV prevalence across survey years and to analyze trends in reported sex behaviors. Results: HIV prevalence among pregnant women ages 15–49 decreased by 72% in urban areas, from 7.1% in 1998 to 2.0% in 2014, and by 75% in rural areas, from 2.0% in 2003 to 0.5% in 2014. HIV declined most in younger age groups, which is a good reflection of recent incidence, with declines of 55% among 15–19-year-olds, 72% among 20–24-year-olds, 40% among 25–29-year-olds, and 7% among those ≥30 years old (considering urban and rural data combined). Data reported in the DHS corroborated these declines in HIV prevalence: between 2003 and 2010, HIV prevalence dropped significantly—by 89% among girls ages 15–19, from 0.9% (95% CI, 0.2 to 1.6) to 0.1% (95% CI, 0.0 to 0.4), and by 78% among young women ages 20–24, from 1.8% (95% CI, 1.6 to 3.0) to 0.4% (95% CI, 0.0 to 0.7). During the same time period, people reported safer sex behaviors. For example, significantly higher percentages of never-married youth reported they had never had sex, lower percentages of sexually active youth reported multiple

  13. Investigation on ionizing radiations emission sources and on workplace radiation safety in medical establishments in Burkina Faso

    International Nuclear Information System (INIS)

    The aims of the investigation were: to identify all the medical establishments using ionizing radiations, to appraise the quality of the buildings and radiation emission equipment, to collect data of workers occupationally exposed and their workplace conditions, and to make suggestions for the safe use of ionizing radiations. Data collected should contribute in the implementation of a Thermo Luminescent Dosimeter (TLD) based individual dosimetry. This study allowed us to know that 36 medical establishments are using ionizing radiations only for conventional radiology. 157 workers are involved in this activity, and many of them are living in Ouagadougou, the capital. We observed that the radiation protection is not well developed in the country, as only 9 of the 36 establishments are provided with photographical dosimeters by Radiation protection and Nuclear Safety Institute (RNSI) of France; radiations measurement instruments are lacking and protection equipment is insufficient. There are no radiological zones marked and no sufficient competences built in radiation protection. Workers don't have clear information on the safety of their workplace. The equipment is for the most old and its maintenance is not regularly done because of lack of skills. So, it is urgent that Burkina Faso regulates radiation protection field. The regulatory authority should take the decrees of application of the law. Radiology services have to be well equipped with protection equipment, radiation measurement equipment, and good quality devices of radiology. The radiology premises must be inspected and building of new ones done according to the norms. Workers are to be well trained about radiation protection and monitored by individual dosimetry in order to fulfil the requirements of the law. (author)

    Background Taenia solium, a zoonotic infection transmitted between humans and pigs, is considered an emerging infection in Sub-Saharan Africa, yet individual and community-level factors associated with the human infection with the larval stages (cysticercosis) are not well understood. This study aims to estimate the magnitude of association of individual-level and village-level factors with current human cysticercosis in 60 villages located in three Provinces of Burkina Faso. Methodology/Principal Findings Baseline cross-sectional data collected between February 2011 and January 2012 from a large community randomized-control trial were used. A total of 3609 individuals provided serum samples to assess current infection with cysticercosis. The association between individual and village-level factors and the prevalence of current infection with cysticercosis was estimated using Bayesian hierarchical logistic models. Diffuse priors were used for all regression coefficients. The prevalence of current cysticercosis varied across provinces and villages ranging from 0% to 11.5%. The results obtained suggest that increased age, being male and consuming pork as well as a larger proportion of roaming pigs and percentage of sand in the soil measured at the village level were associated with higher prevalences of infection. Furthermore, consuming pork at another village market had the highest increased prevalence odds of current infection. Having access to a latrine, living in a household with higher wealth quintiles and a higher soil pH measured at the village level decreased the prevalence odds of cysticercosis. Conclusions/Significance This is the first large-scale study to examine the association between variables measured at the individual-, household-, and village-level and the prevalence odds of cysticercosis in humans. Factors linked to people, pigs, and the environment were of importance, which further supports the need for a One Health approach to control

    Public utility of electricity gathers the production, the transformation, the distribution, the import, the export and the sale of electrical energy. The public utility of electricity is ensured by the State, the territorial collectivity or by thirds under terms of contracts signed with the State or the territorial collectivities. The offer of electricity is exclusively assured by the SONABEL. Its total production in 2006 was 548,397,372 kWh compared with 516,224,848 in 2005, that is to say an increase of 6.23%. The imported energy in 2006 was 139,323,910 kWh; that accounts for 25% of total energy produced. The thermal production was about 467.728.921 kWh against 415,751,943 kWh in 2005, that is to say an increase of 13%. Water power represented 8,068,451 kWh in 2006, that is to say a fall of 20%. In Burkina Faso, total energy offered (energy imported, heat energy, hydroelectric power) is increase by 7.19% in comparison to 2005 and reached up of 687,721,282 kWh in 2006. In spite of this important electrical production, only 7 to 8% of the total population have electricity. That is mainly caused by the capital cost of electricity installations. To mitigate this difficulty, a national policy of energy was developed to strengthen the access of electricity to the population, to fall the costs of electricity, to develop rural electrification and to growth on the part of renewable energies in the national energy assessment. That is why it is necessary to implement the project of access to the energy services (PASE) whose overall cost is estimated to 41.1 million US dollars

    Full Text Available Abstract Background The clinical presentation of malaria, considered as the result of a complex interaction between parasite and human genetics, is described to be different between rural and urban areas. The analysis of the Plasmodium falciparum genetic diversity in children with uncomplicated malaria, living in these two different areas, may help to understand the effect of urbanization on the distribution of P. falciparum genotypes. Methods Isolates collected from 75 and 89 children with uncomplicated malaria infection living in a rural and an urban area of Burkina Faso, respectively, were analysed by a nested PCR amplification of msp1 and msp2 genes to compare P. falciparum diversity. Results The K1 allelic family was widespread in children living in the two sites, compared to other msp1 allelic families (frequency >90%. The MAD 20 allelic family of msp1 was more prevalent (p = 0.0001 in the urban (85.3% than the rural area (63.2%. In the urban area, the 3D7 alleles of msp2 were more prevalent compared to FC27 alleles, with a high frequency for the 3D7 300bp allele (>30%. The multiplicity of infection was in the range of one to six in the urban area and of one to seven in the rural area. There was no difference in the frequency of multiple infections (p = 0.6: 96.0% (95% C.I: 91.6–100 in urban versus 93.1% (95%C.I: 87.6–98.6 in rural areas. The complexity of infection increased with age [p = 0.04 (rural area, p = 0.06 (urban area]. Conclusion Urban-rural area differences were observed in some allelic families (MAD20, FC27, 3D7, suggesting a probable impact of urbanization on genetic variability of P. falciparum. This should be taken into account in the implementation of malaria control measures.

    Full Text Available This paper addresses the education of young Muslims in Burkina Faso through relevant literature analysis and the authors’ observations, highlighting the pathways of study in Arabic-speaking countries and the social dynamics around them. The central theme is associated with the more general debate about education and diversity, because it discusses, on the one hand, the educational hegemony of secular orientation carried out in French adopted by part of the society and made official by the nation-state; on the other hand, it stresses the movement of another part of society that continues to enroll their children in Muslim schools where teaching is conducted in Arabic or bilingual (French and Arabic. The study describes the sociopolitical contexts that constitute the institutions of Islamic education, emphasizing the importance of Franco-Arabic schools and new Muslim private universities from the non-public higher education network. Following this discussion, there is a debate about the contribution of these young graduated men and women (inside and outside the country to hold and maintain the educational system. This paper also highlights the political action of these groups that claims for citizenship through religious practices. We conclude by stressing the existence of the fundamental contribution of Islam, which remains a powerful space for the construction of social and interpersonal meanings even in post-colonial dynamics. This is the scenario in which the reconstruction of networks may be converted into an overall challenge for social occupational therapy to mediate conflicts emerging from the confrontation of values and social practices.

    Soil and water samples were collected from a watershed in Burkina Faso where illegal artisanal gold extraction using cyanidation occurs. The samples were used to evaluate cyanide contamination and the presence of cyanide degrading bacteria (CDB). Free cyanide (F-CN) was detected in all samples, with concentrations varying from 0.023 to 0.9 mg kg(-1), and 0.7-23 μg L(-1) in the soil and water samples, respectively. Potential CDB also were present in the samples. To test the effective F-CN degradation capacity of the isolated CDB species, the species were cultivated in growth media containing 40, 60 or 80 mg F-CN L(-1), with or without nutrients, at pH 9.5 and at room temperature. More than 95% of F-CN was degraded within 25 h, and F-CN degradation was associated with bacterial growth and ammonium production. However, initial concentrations of F-CN higher than 100 mg L(-1) inhibited bacterial growth and cyanide degradation. Abiotic tests showed that less than 3% of F-CN was removed by volatilization. Thus, the degradation of F-CN occurred predominately by biological mechanisms, and such mechanisms are recommended for remediation of contaminated soil and water. The bacteria consortium used in the experiment described above exist in a Sahelian climate, which is characterized by a long hot and dry season. Because the bacteria are already adapted to the local climate conditions and show the potential for cyanide biodegradation, further applicability to other contaminated areas in West Africa, where illegal gold cyanidation is widespread, should be explored.

    2015-07-01

    Full Text Available Climate variability and change significantly affect smallholder farmers’ food security and livelihoods in sub-Saharan Africa. Tree planting is one of the measures promoted by development programs to mitigate and adapt to climate change. Tree planting is also believed to positively contribute to livelihoods. This paper examines factors influencing smallholders’ tree planting activities in four villages in the Ziro province, Southern Burkina Faso. Furthermore, it analyses the challenges encountered and willingness to continue tree planting under current tenure arrangements. The data was obtained through key informants, household interviews, focus group discussions, and field observations. Results indicate that the majority of farmers interviewed planted Mangifera indica (50%, Anacardium occidentale (32% and Moringa oleifera (30%. In a number of trees planted, Eucalyptus camaldulensis, Mangifera indica and Anacardium occidentale dominated. Tree planters were mainly farmers who held large and old farm areas, were literate and relatively wealthy, had favorable attitudes toward tree planting, and with considerable years of participation in a farmers’ group. The main reasons for planting trees included income generation from the sale of tree products, access to markets and local support for tree planting. Preference for agriculture, tenure insecurity and lack of sufficient land were the main reasons cited for not planting trees. Farm households that were relatively poor, had smaller workforces and smaller farm sizes were not willing to continue tree planting. To effectively engage farmers in tree planting and to make it more attractive, policies are needed that address tenure insecurity for migrants, enable better access to markets, and support fair pricing structures for wood and other tree resources.

    The vaginal swabs among HIV-positive women in Africa often revealed opportunistic infections such as human Papillomavirus (HPV) and Mycoplasma that induce respectively cervix cancer and diseases such as vaginosis, abortions, infertility in through salpingitis. The purposes of this study were to: (1) seek for, the prevalence of pathogens such as HPV and Mycoplasma; (2) characterize the strains of HPV and estimate their prevalence; (3) identify among these women, those who were co-infected by these pathogens in order to cure them. From February 2009 to January 2010, 156 HIV-positive women attending our medical centers and aged from 19-45 years (mean age 33.65 +/- 5.75 years) had voluntarily accepted vaginal specimen's tests. PCR, ELISA and molecular hybridization were used for the identification and characterization of these pathogens. The results revealed the presence of Mycoplasma and HPV in 25.64 and 58.33% cases, respectively. The following HPV genotypes and the following prevalence were recorded: HPV-50'S (24.11%), HPV-18 (21.28%), HPV-30'S (18.44%) and HPV-16 (5.67%). The study also enable the identification of co-infections such as HPV-18 strains with HPV-30'S (5.67%) and HPV-30'S with HPV-50'S (3.55%). Other germs infecting the female genital tract including Candida albicans (20.51%), Escherichia coli (12.18%), Treponema pallidum (3.85%), Streptococcus agalactiae (3.21%) and Staphylococcus aureus (1.92%) were isolated. This preliminary research work showed the incidence of several genital pathogens, this could be a springboard for nationwide epidemiological study on HPV strains circulating in Burkina Faso.

  1. Use of isotopic and non-nuclear techniques to evaluate water dynamics in agroforestry parklands in Sapone, Burkina Faso

    International Nuclear Information System (INIS)

    Full text: In sub-Saharan Africa, trees are preserved on farmed fields forming agroforestry parkland systems, which are dominated in West Africa by Vitellaria paradoxa C.F. Gaertn or karite and Parkia biglobosa (Jacq.) Benth or nere. Negative impacts of karite and nere on associated crops have been reported leading to a reduction of crop production. Amongst the reasons of such reduction is the competition for nutrients and water. However, through limitation of soil evaporation and Hydraulic Lift (HL) there might also be facilitation with higher growth and better water status of understorey plants in some circumstances (dry climatic zones, poor rainy seasons). The present study was carried out in the parklands of Sapone, Burkina Faso. Six mature trees of karite and six of nere were selected with a special attention for the crown size. Three trees of each species were completely pruned and the other three served as controls. Before pruning, the area around each tree was subdivided into four concentric tree influence zones: 0 to 2 m from the trunk (zone A); from 2 m to half diameter of the crown (zone B), from half diameter to the edge of the crown (zone C), from the edge of the crown to 3 m outside of the crown (zone D). Thus we (1) characterized the wetting profile under which trees (karite and nere) and associated crops were growing by monitoring soil water; (2) investigated HL in the same tree species in agroforestry parklands of dry savannas in West Africa. We monitored soil water using Diviner 2000, soil water potential (ψs) using Psychrometers and the source of water used by trees and crops by measuring the stable isotopic ratio of plant and source waters. The present article is presenting the results of all these investigations. (author)

    This study investigates the impacts of land use change on water resources in the Dano catchment, Burkina Faso, using a physically based hydrological simulation model and land use scenarios. Land use dynamic in the catchment was assessed through the analysis of four land use maps corresponding to the land use status in 1990, 2000, 2007, and 2013. A reclassification procedure levels out differences between the classification schemes of the four maps. The land use maps were used to build five land use scenarios corresponding to different levels of land use change in the catchment. Water balance was simulated by applying the Water flow and balance Simulation Model (WaSiM) using observed discharge, soil moisture, and groundwater level for model calibration and validation. Model statistical quality measures (R2, NSE and KGE) achieved during calibration and validation ranged between 0.6 and 0.9 for total discharge, soil moisture, and groundwater level, indicating a good agreement between observed and simulated variables. After a successful multivariate validation the model was applied to the land use scenarios. The land use assessment exhibited a decrease of savannah at an annual rate of 2% since 1990. Conversely, cropland and urban areas have increased. Since urban areas occupy only 3% of the catchment it can be assumed that savannah was mainly converted to cropland. The conversion rate of savannah was lower than the annual population growth of 3%. A clear increase in total discharge (+17%) and decrease in evapotranspiration (-5%) was observed following land use change in the catchment. A strong relationship was established between savannah degradation, cropland expansion, discharge increase and reduction of evapotranspiration. The increase in total discharge is related to high peak flow, suggesting (i) an increase in water resources that are not available for plant growth and human consumption and (ii) an alteration of flood risk for both the population within and

    Full Text Available Present study was aimed to understand the scientific basis of the farmer’s nomenclature of the local varieties of Cleome gynandra L. and to identify the characters of interests that can be used for the varietal improvement of the species. A survey was carried o ut in five cities of Burkina Faso with 56 producers of C. gynandra with the help of semi-structured interviews to identify the preferential characters. Furthermore thirty accessions were collected and evaluated in July 2014 at Gampela according to randomized complete block design with seventeen variables. The study revealed that in the denomination of local varieties, the farmers use agromorphological characters such as the color of the stem, leaves and the vegetative cycle of the plant. It was also revealed that the selection of plant in the vegetable garden s is preferred for the green color of the stem, leaves, long vegetative cycle, height of the plant, dimensions of the leaves and the number of primary branches. These were the selective interests for the farmers identified during the survey. The study also revealed that the process of selection is more advanced in Ouagado ugo u, where the demand is very high and where the consumers are more as compared to the other localities where the choice of the plant has just began for consumption. The results of this study have permitted to undertake the varietal improvement of the species according to the needs of the producers whose majority have a particular preference for the green ecotypes with long cycle.

    Full Text Available This study investigates the long term economic impact of severe obstetric complications for women and their children in Burkina Faso, focusing on measures of food security, expenditures and related quality of life measures. It uses a hospital based cohort, first visited in 2004/2005 and followed up four years later. This cohort of 1014 women consisted of two main groups of comparison: 677 women who had an uncomplicated delivery and 337 women who experienced a severe obstetric complication which would have almost certainly caused death had they not received hospital care (labelled a "near miss" event. To analyze the impact of such near miss events as well as the possible interaction with the pregnancy outcome, we compared household and individual level indicators between women without a near miss event and women with a near miss event who either had a live birth, a perinatal death or an early pregnancy loss. We used propensity score matching to remove initial selection bias. Although we found limited effects for the whole group of near miss women, the results indicated negative impacts: a for near miss women with a live birth, on child development and education, on relatively expensive food consumption and on women's quality of life; b for near miss women with perinatal death, on relatively expensive foods consumption and children's education and c for near miss women who had an early pregnancy loss, on overall food security. Our results showed that severe obstetric complications have long lasting consequences for different groups of women and their children and highlighted the need for carefully targeted interventions.

    Full Text Available Background: A growing body of evidence points to the emission of greenhouse gases from human activity as a key factor in climate change. This in turn affects human health and wellbeing through consequential changes in weather extremes. At present, little is known about the effects of weather on the health of sub-Saharan African populations, as well as the related anticipated effects of climate change partly due to scarcity of good quality data. We aimed to study the association between weather patterns and daily mortality in the Nouna Health and Demographic Surveillance System (HDSS area during 1999–2009. Methods: Meteorological data were obtained from a nearby weather station in the Nouna HDSS area and linked to mortality data on a daily basis. Time series Poisson regression models were established to estimate the association between the lags of weather and daily population-level mortality, adjusting for time trends. The analyses were stratified by age and sex to study differential population susceptibility. Results: We found profound associations between higher temperature and daily mortality in the Nouna HDSS, Burkina Faso. The short-term direct heat effect was particularly strong on the under-five child mortality rate. We also found independent coherent effects and strong associations between rainfall events and daily mortality, particularly in elderly populations. Conclusion: Mortality patterns in the Nouna HDSS appear to be closely related to weather conditions. Further investigation on cause-specific mortality, as well as on vulnerability and susceptibility is required. Studies on local adaptation and mitigation measures to avoid health impacts from weather and climate change is also needed to reduce negative effects from weather and climate change on population health in rural areas of the sub-Saharan Africa.

    Full Text Available Several studies have observed that the structure underlying both normal personality and personality disorders is stable across cultures. Most of this cross-cultural research was conducted in Western and Asian cultures. In Africa, the few studies were conducted with well-educated participants using French or English instruments. No research was conducted in Africa with less privileged or preliterate samples. The aim of this research was to study the structure and expression of normal and abnormal personality in an urban and a rural sample in Burkina Faso. The sample included 1750 participants, with a sub-sample from the urban area of Ouagadougou (n = 1249 and another sub-sample from a rural village, Soumiaga (n = 501. Most participants answered an interview consisting of a Mooré language adaptation of the Revised NEO Personality Inventory and of the International Personality Disorders Examination. A sub-sample completed the same instruments in French. Demographic variables only have a small impact on normal and abnormal personality traits. The structure underlying normal personality was unstable across regions and languages, illustrating that translating a complex psychological inventory into a native African language is a very difficult task. The structure underlying abnormal personality was stable across regions, scales reaching even metric equivalence. As scalar equivalence was not reached, mean differences cannot be interpreted. Nevertheless, these differences could be due to an exaggerated expression of abnormal traits valued in the two cultural settings. Our results suggest that studies using a different methodology should be conducted to understand what is considered, in different cultures, as deviating from the expectations of the individual’s culture, and as a significant impairment in self and interpersonal functioning, as defined by the DSM-5.

    Full Text Available Despite efforts expended over recent decades, there is a persistent gap between the production of scientific evidence and its use. This is mainly due to the difficulty of bringing such knowledge to health workers and decision-makers so that it can inform practices and decisions on a timely basis. One strategy for transferring knowledge to potential users, that is, gaining increasing legitimacy, is knowledge brokering (KB, effectiveness of which in certain conditions has been demonstrated through empirical research. However, little is known about how to implement such a strategy, especially in the African context. The KB program presented here is aimed specifically at narrowing the gap by making scientific knowledge available to users with the potential to improve health-related practices and decision making in Burkina Faso. The program involves Canadian and African researchers, a knowledge broker, health practitioners, and policy-makers. This article presents the collaborative development of the KB strategy and the evaluation of its implementation at year 1. The KB strategy was developed in stages, beginning with a scoping study to ensure the most recent studies were considered. Two one-day workshops were then conducted to explore the problem of low research use and to adapt the strategy to the Burkinabè context. Based on these workshops, the KB program was developed and brokers were recruited and trained. Evaluation of the program's implementation after the first year showed that: 1 the preparatory activities were greatly appreciated by participants, and most considered the content useful for their work; 2 the broker had carried out his role in accordance with the logic model; and 3 this role was seen as important by the participants targeted by the activities and outputs. Participants made suggestions for program improvements in subsequent years, stressing particularly the need to involve decision-makers at the central level.

    Full Text Available BACKGROUND: The aim of this study was to determine the incidence and seasonal pattern of malaria in children in South-West Burkina Faso, and to compare, in a randomized trial, characteristics of cases detected by active and passive surveillance. This study also enabled the planning of a malaria vaccine trial. METHODS: Households with young children, located within 5 kilometers of a health facility, were randomized to one of two malaria surveillance methods. In the first group, children were monitored actively. Each child was visited twice weekly; tympanic temperature was measured, and if the child had a fever or history of fever, a malaria rapid diagnostic test was performed and a blood smear collected. In the second group, children were monitored passively. The child's parent or caregiver was asked to bring the child to the nearest clinic if he was unwell. Follow up lasted 13 months from September 2009. RESULTS: Incidence of malaria (Fever with parasitaemia ≥5,000/µL was 1.18 episodes/child/year in the active cohort and 0.89 in the passive cohort (rate ratio 1.32, 95% CI 1.13-1.54. Malaria cases in the passive cohort were more likely to have high grade fever; but parasite densities were similar in the two groups. Incidence was highly seasonal; when a specific case definition was used, about 60% of cases occurred within the 4 months June-September. CONCLUSION: Passive case detection required at least a 30%-40% increase in the sample size for vaccine trials, compared to active detection, to achieve the same power. However we did not find any evidence that parasite densities were higher with passive than with active detection. The incidence of malaria is highly seasonal and meets the WHO criteria for Seasonal Malaria Chemoprevention (SMC. At least half of the malaria cases in these children could potentially be prevented if SMC was effectively deployed.

    Full Text Available The bioaccumulation and biomagnification of mercury (Hg and selenium (Se were investigated in sub-tropical freshwater food webs from Burkina Faso, West Africa, a region where very few ecosystem studies on contaminants have been performed. During the 2010 rainy season, samples of water, sediment, fish, zooplankton, and mollusks were collected from three water reservoirs and analysed for total Hg (THg, methylmercury (MeHg, and total Se (TSe. Ratios of δ13C and δ15N were measured to determine food web structures and patterns of contaminant accumulation and transfer to fish. Food chain lengths (FCLs were calculated using mean δ15N of all primary consumer taxa collected as the site-specific baseline. We report relatively low concentrations of THg and TSe in most fish. We also found in all studied reservoirs short food chain lengths, ranging from 3.3 to 3.7, with most fish relying on a mixture of pelagic and littoral sources for their diet. Mercury was biomagnified in fish food webs with an enrichment factor ranging from 2.9 to 6.5 for THg and from 2.9 to 6.6 for MeHg. However, there was no evidence of selenium biomagnification in these food webs. An inverse relationship was observed between adjusted δ15N and log-transformed Se:Hg ratios, indicating that Se has a lesser protective effect in top predators, which are also the most contaminated animals with respect to MeHg. Trophic position, carbon source, and fish total length were the factors best explaining Hg concentration in fish. In a broader comparison of our study sites with literature data for other African lakes, the THg biomagnification rate was positively correlated with FCL. We conclude that these reservoir systems from tropical Western Africa have low Hg biomagnification associated with short food chains. This finding may partly explain low concentrations of Hg commonly reported in fish from this area.

    In Sub-Sahara Africa, malaria inflicts a high healthcare expenditure to individuals. However, little is known about healthcare expenditure to individual affected by malaria and determinants of healthcare seeking behaviour in urban settings where private sector is thriving. This study investigated the level and correlates of expenditure among individuals with self-reported malaria episode in Ouagadougou, Burkina Faso. A cross-sectional household survey conducted in August-November 2011 in Ouagadougou covered 8,243 individuals (1,600 households). Using Generalized Estimating Equations, the analysis included 1082 individuals from 715 households, who reported an episode of malaria. Of individuals surveyed, 38.3% sought care from public, 27.4% from private providers, and, 34.2% self-medicated. The median cost for malaria treatment was USD10.1 (4,850.0XOF) with significant different between public, private and self-medication (p<0.001). In public primary care health facilities, the median cost was USD8.4 (4,050.0XOF) for uncomplicated malaria and USD15.2 (7,333.5XOF) for severe malaria. In private-for-profit facilities run by a medical doctor, the median cost was USD30.3 (14,600.0XOF) for uncomplicated malaria and USD 43.0 (20,725.0XOF) for severe malaria. Regardless of the source of care, patients with insurance incurred significantly higher expenditure compared to those without insurance (p<0.001) and medicine accounted for the largest share of the expenditure. The type of provider, having insurance, and the severity of the malaria predict the amount of money spent. The high financial cost of malaria treatment regardless of the providers poses threat to the goal of universal access to malaria interventions, the unique way to achieve elimination goals.

    Full Text Available Abstract Okra leaf curl disease (OLCD is a major constraint on okra (Abelmoschus esculentus production and is widespread in Africa. Using a large number of samples representative of the major growing regions in Burkina Faso (BF, we show that the disease is associated with a monopartite begomovirus and satellite DNA complexes. Twenty-three complete genomic sequences of Cotton leaf curl Gezira virus (CLCuGV isolates associated with OLCD, sharing 95 to 99% nucleotide identity, were cloned and sequenced. Six betasatellite and four alphasatellite (DNA-1 molecules were also characterized. The six isolates of betasatellite associated with CLCuGV isolates correspond to Cotton leaf curl Gezira betasatellite (CLCuGB (88 to 98% nucleotide identity. One isolate of alphasatellite is a variant of Cotton leaf curl Gezira alphasatellite (CLCuGA (89% nucleotide identity, whereas the three others isolates appear to correspond to a new species of alphasatellite (CLCuGA most similar sequence present 52 to 60% nucleotide identity, provisionally named Okra leaf curl Burkina Faso alphasatellite (OLCBFA. Recombination analysis of the viruses demonstrated the interspecies recombinant origin of all CLCuGV isolates, with parents being close to Hollyhock leaf crumple virus (AY036009 and Tomato leaf curl Diana virus (AM701765. Combined with the presence of satellites DNA, these results highlight the complexity of begomoviruses associated with OLCD.

    Full Text Available Dans la première moitié du XXème siècle, alors que la Haute-Volta (actuel Burkina Faso subissait une terrible épidémie de maladie du sommeil, l’administration coloniale française a orchestré des déplacements massifs de populations de la Haute-Volta vers la Côte d’Ivoire, pour exploiter le territoire. Cela a conduit à la mise en place de villages de colonisation Mossi en zone forestière ivoirienne, comme ceux de Koudougou, issus de l’une des régions les plus peuplées de Haute-Volta, mais aussi l’une des plus touchées par la maladie du sommeil. Depuis 2000, au Burkina Faso, c’est dans le district sanitaire de Koudougou que sont dépistés passivement le plus grand nombre de trypanosomés en provenance de Côte d’Ivoire. Qui sont-ils ? Où habitent-ils au Burkina Faso ? D’où viennent-ils de Côte d’Ivoire ? Après avoir retracé l’histoire épidémiologique des villages de Koudougou au Burkina Faso et en Côte d’Ivoire, nous avons recherché les trypanosomés dépistés passivement depuis 2000 dans le district sanitaire de Koudougou au Burkina Faso. Au total, dix trypanosomés ont été enquêtés. Le processus de propagation de la maladie du sommeil dans l’espace ivoiro-burkinabé a été mis en évidence et des zones à risque de la maladie identifiées dans ce même espace.

    Full Text Available Sorghum production in a Piliostigma reticulatum Park in the North Sudanian Zone of Burkina Faso. En zone sahélo-soudanienne, les systèmes de production sont des associations cultures-ligneux. Les ligneux sélectionnés sont des espèces fruitières et/ou à rôle écologique prouvé. Face à l'aridification climatique, les populations adoptent de plus en plus l'espèce Piliostigma reticulatum. De manière à quantifier l'impact de cette espèce sur la production du sorgho, principale culture de la région, quinze pieds de Piliostigma reticulatum, âgés de 7 ans ont été suivis en association avec le sorgho blanc, pendant trois ans. Les paramètres suivis sont: la croissance et les composantes du rendement. Des échantillons de sol ont été prélevés pour déterminer les effets de l'espèce sur les propriétés du sol. Les trois traitements comparés étaient: culture sous houppier, culture à la limite du houppier et culture hors houppiers. Sous le houppier de Piliostigma reticulatum, le statut du carbone organique est amélioré de 67 % dans l'horizon 0-10 cm et de 46% dans l'horizon 10-20 cm. Le taux d'azote total est amélioré de 62% dans l'horizon 0-10 cm. En outre, le rapport C/N présente des valeurs relativement faibles. A 30 jour après le semis, on constate une meilleure croissance du sorgho sous houppier par rapport aux placettes hors houppier. Cependant, selon les années, la meilleure croissance initiale sous houppier ne se traduit pas nécessairement par des gains de production en paille et en grains du sorgho par rapport aux autres placettes. Des investigations complémentaires sont nécessaires pour expliquer ces observations et évaluer l'intérêt de cette association pour les agriculteurs.

    African cities are presently facing the combined impacts of growing urbanization and climate change. In several instances; providing safe drinking water for all is still a challenge, especially for cities located on basement aquifers, were groundwater is scarce. Here we assess the effects of climate change and land use change on groundwater amount and quality in the main city of Ouagadougou (Burkina Faso) taking advantage of the CIEH borehole, where a mostly continuous record lasts since 1978. This record spans most of the Great African Drought (1970-1990) and recovery from the Drought since the 2000s. A piezometric network of 14 wells and boreholes was setup around the CIEH borehole and monitored during the 2013-2014 hydrologic year. The piezometric network spans an old settlement, the Ouagadougou University, a vegetable gardening area and a natural forested area. Water balance estimates are provided by a 1D box model. The study area, although it lies partly on an old settlement in Ouagadougou and on the University area, presents a rather uniform runoff coefficient of 22% and ET amounting to 80-90 % of rainfall, which usually characterizes natural areas. It is suspected that the almost absence of asphalted surfaces, the presence of trees and flow of rainwater from roofs toward bare soils or sumps could be responsible of this budget. However, the two wells located in the forested Bangr Weogo recreational area are characterized by almost no runoff and a nearly 100 % ET. While drinking water can be pumped in several places in the city of Ouagadougou, chemical major analyses show that two mechanisms impact groundwater quality during the rainy season: (i) rise of the water table at pit latrine level, mainly in old settlements, and entrainment of harmful substances from soil to the aquifer in gardening area near some artisan activities. The CIEH borehole is not fully representative of its neighboring area since (i) it lies in a piezometric low, (ii) it presents the

    Full Text Available Abstract Background Despite rapid and tangible progress in vaccine coverage and in premature mortality rates registered in sub-Saharan Africa, inequities to access remain firmly entrenched, large pockets of low vaccination coverage persist, and coverage often varies considerably across regions, districts, and health facilities' areas of responsibility. This paper focuses on system-related factors that can explain disparities in immunization coverage among districts in Burkina Faso. Methods A multiple-case study was conducted of six districts representative of different immunization trends and overall performance. A participative process that involved local experts and key actors led to a focus on key factors that could possibly determine the efficiency and efficacy of district vaccination services: occurrence of disease outbreaks and immunization days, overall district management performance, resources available for vaccination services, and institutional elements. The methodology, geared toward reconstructing the evolution of vaccine services performance from 2000 to 2006, is based on data from documents and from individual and group interviews in each of the six health districts. The process of interpreting results brought together the field personnel and the research team. Results The districts that perform best are those that assemble a set of favourable conditions. However, the leadership of the district medical officer (DMO appears to be the main conduit and the rallying point for these conditions. Typically, strong leadership that is recognized by the field teams ensures smooth operation of the vaccination services, promotes the emergence of new initiatives and offers some protection against risks related to outbreaks of epidemics or supplementary activities that can hinder routine functioning. The same is true for the ability of nurse managers and their teams to cope with new situations (epidemics, shortages of certain stocks. Conclusion

  17. Decreased motivation in the use of insecticide-treated nets in a malaria endemic area in Burkina Faso

    Full Text Available Abstract Background The use of insecticide-treated nets (ITN is an important tool in the Roll Back Malaria (RBM strategy. For ITNs to be effective they need to be used correctly. Previous studies have shown that many factors, such as wealth, access to health care, education, ethnicity and gender, determine the ownership and use of ITNs. Some studies showed that free distribution and public awareness campaigns increased the rate of use. However, there have been no evaluations of the short- and long-term impact of such motivation campaigns. A study carried out in a malaria endemic area in south-western Burkina Faso indicated that this increased use declined after several months. The reasons were a combination of the community representation of malaria, the perception of the effectiveness and usefulness of ITNs and also the manner in which households are organized by day and by night. Methods PermaNet 2.0® and Olyset® were distributed in 455 compounds at the beginning of the rainy season. The community was educated on the effectiveness of nets in reducing malaria and on how to use them. To assess motivation, qualitative tools were used: one hundred people were interviewed, two hundred houses were observed directly and two houses were monitored monthly throughout one year. Results The motivation for the use of bednets decreased after less than a year. Inhabitants' conception of malaria and the inconvenience of using bednets in small houses were the major reasons. Acceptance that ITNs were useful in reducing malaria was moderated by the fact that mosquitoes were considered to be only one of several factors which caused malaria. The appropriate and routine use of ITNs was adversely affected by the functional organization of the houses, which changed as between day and night. Bednets were not used when the perceived benefits of reduction in mosquito nuisance and of malaria were considered not to be worth the inconvenience of daily use. Conclusion In

    Knowledge of climate variability is relevant and challenging for farmers, decision makers and population in general. Ninety percent of Burkina Faso active population is engaged in agriculture and livestock, which accounts for 39% of gross domestic product. Located between the coordinates 1o15'-1o55' West and 12o17'- 12o50'North, Massili basin includes Ouagadougou the capital and has four dams, of which the most important dam, Loumbila is used for the capital water supply and irrigation. A change of climate may affect the water resources most likely limit the access to safe water. In order to characterize Massili basin climate variability, daily temperature and precipitation over 1960 to 2012 was analyzed using long-term records from the Ouagadougou synoptic station. By applying R-climdex and instat tools, indices were calculated by a consistent approach recommended by the World Meteorological Organization Expert Team on Climate Change Detection and Indices. The precipitation parameters computed were: the maximum 5-day precipitationamount; the number of days with precipitation amount ≥50 mm ; the maximum precipitation amount in consecutive wet days with RR≥ 1mm; the consecutives dry days;the extremely wet days ; the extreme precipitation in one day, the total precipitation in wet days; the temperature indices computed were : the maximum of the maximum daily temperature, the minimum of daily maximum temperature,the minimum of daily minimum temperature,the cold spell duration indices and the warm spell duration indicator. Results show a slight increase of the maximum 5-day precipitation, maximum precipitation amount in consecutive wet days with RR≥1mm, the onset delayed and the cessation is earlier meaning that the rainfall period is shortening. The total precipitationwas decreased in the basin but there is a slight increase in the occurrence of extremely wet days. CSDI is decreasing while warm spell duration indices are increasing.

    Introduction The scale-up of highly active antiretroviral therapy (HAART) has led to a significant improvement in survival of the HIV-positive patient but its effects on health-related quality of life (HRQOL) are less known and context-dependent. Our aim was to assess the temporal changes and factors associated with HRQOL among HIV-positive adults initiating HAART in Burkina Faso. Methods HIV-positive people initiating HAART were prospectively included and followed over a one-year period in three HIV clinics of Ouagadougou. HRQOL was assessed at baseline and at each follow-up visit using physical (PHS) and mental (MHS) summary scores derived from the Medical Outcome Study 36-Item short-form health survey (MOS SF-36) questionnaire. Toxicity related to HAART modification and self-reported symptoms were recorded during follow-up visits. Determinants associated with baseline and changes in both scores over a one-year period were assessed using a mixed linear model. Results A total of 344 patients were included. Their median age at baseline was 37 years [interquartile range (IQR) 30–44] and their median CD4 count was 181 cells/mm3 (IQR 97–269). The mean [standard deviation (SD)] PHS score increased from 45.4 (11.1) at baseline to 60.0 (3.1) at 12 months (p<10−4) and the mean (SD) MHS score from 42.2 (8.7) to 43.9 (3.4) (p<10−2). After one year of treatment, patients that experienced on average two symptoms during follow-up presented with significantly lower PHS (63.9) and MHS (43.8) scores compared to patients that presented no symptoms with PHS and MHS of 68.2 (p<10−4) and 45.3 (p<10−3), respectively. Discussion The use of HAART was associated with a significant increase in both physical and mental aspects of the HRQOL over a 12-month period in this urban African population. Perceived symptoms experienced during follow-up visits were associated with a significant impairment in HRQOL. The appropriate and timely management of reported symptoms during the

    We investigated contraceptive practices in the rural health district of Kaya in Burkina Faso with the aim of a) comparing the sociodemographic and cultural characteristics of individuals who were well and poorly informed concerning contraceptive methods; b) analyzing the pattern of use of these contraceptive methods by the populations. We carried out a two-level cluster survey by the Hendersen method. For each household investigated, the chief, his wife (or one wife selected at random in polygamous families) and an adolescent (or one adolescent selected at random if there was more than one adolescent) were interviewed. Significantly more men than women were well informed concerning contraceptive methods. Similarly, a higher proportion of male adolescents than of female adolescents were well informed concerning contraceptive methods. The individuals who were well informed concerning contraceptive methods differed from those who were not well informed in terms of age, religion, level of education and radio listening habits. The prevalence of use of contraceptive methods in this study was found to be 4 to 36%, depending on the group studied. The majority of individuals expressed an intention to use contraceptive methods in the future: 59 to 78%, depending on the group studied. The contraceptive methods chosen for current and future use were, in order: the pill, condoms and contraceptive implants and the intrauterine device. Current patterns of contraceptive use favor, in decreasing order of preference, abstinence, the pill, condoms and contraceptive implants. There was also a strong tendency for individuals to experiment with diverse contraceptive methods. Thus, in the future, there is likely to be a trend towards the abandoning of abstinence in favor of the pill, condoms and contraceptive implants. Of these newer methods, condoms are likely to be the least popular and their relegation to a lower level of importance is likely to have disastrous consequences in terms

    The 2007/2008 food prices hike has increased the interest in social safety nets programmes to fight food insecurity. Targeting the most in need is central to achieve effectiveness of such interventions. In 2009 in Ouagadougou, Burkina Faso, a food voucher (FV) programme targeted the 25 000 most vulnerable households (8.3% of the population). Targeting used a two-stage process: first geographical selection of poorest districts (∼90 000 households); then, in those districts, identification of the most vulnerable households according to a proxy-means test (PMT). Targeted households were entitled to receive FV for 1 year. A first survey was conducted at the beginning of the FV distribution on a representative sample of 2273 households drawn from the poorest districts. One year later a second survey, conducted on a subsample of same households (n = 901), identified those who actually received FV (beneficiary). The performance of the whole process was assessed against household food expenditure, used as the reference measure for vulnerability with a cut-off point of 1513 FCFA (corresponding to the 8.3th percentile of the distribution of expenditure). The 'normalized share of transfers going to vulnerable households' (NSTVH), i.e. proportion of FVs allocated to households below the cut-point, was the main criteria of judgement. Almost twice as many FV were allocated to vulnerable households as compared with a theoretical random distribution all over Ouagadougou (NSTVH = 1.85). When considering the sole targeted districts the NSTVH was only 0.84 (i.e. no more effective than a random distribution), meaning that the geographical stage was effective to select vulnerable districts while the PMT did not perform well to identify the most vulnerable households in those districts. Results could have been improved if only targeted households had received FV (NSTVH = 2.61 and 1.18 for the whole Ouagadougou and targeted districts, respectively). Improved targeting

    Full Text Available Abstract Background WHO estimates suggest that age-specific death rates from non-communicable diseases are higher in sub-Saharan Africa than in high-income countries. The objectives of this study were to examine, in Burkina Faso, the prevalence of non-communicable disease symptoms by age, gender, socioeconomic group and setting (rural/urban, and to assess gender and socioeconomic inequalities in the prevalence of these symptoms. Methods We obtained data from the Burkina Faso World Health Survey, which was conducted in an adult population (18 years and over with a high response rate (4822/4880 selected individuals. The survey used a multi-stage stratified random cluster sampling strategy to identify participants. The survey collected information on socio-demographic and economic characteristics, as well as data on symptoms of a variety of health conditions. Our study focused on joint disease, back pain, angina pectoris, and asthma. We estimated prevalence correcting for the sampling design. We used multiple Poisson regression to estimate associations between non-communicable disease symptoms, gender, socioeconomic status and setting. Results The overall crude prevalence and 95% confidence intervals (CI were: 16.2% [13.5; 19.2] for joint disease, 24% [21.5; 26.6] for back pain, 17.9% [15.8; 20.2] for angina pectoris, and 11.6% [9.5; 14.2] for asthma. Consistent relationships between age and the prevalence of non-communicable disease symptoms were observed in both men and women from rural and urban settings. There was markedly high prevalence in all conditions studied, starting with young adults. Women presented higher prevalence rates of symptoms than men for all conditions: prevalence ratios and 95% CIs were 1.20 [1.01; 1.43] for joint disease, 1.42 [1.21; 1.66] for back pain, 1.68 [1.39; 2.04] for angina pectoris, and 1.28 [0.99; 1.65] for asthma.

Over a decade of preventive chemotherapy has been implemented through annual lymphatic filariasis (LF mass drug administration (MDA for population aged five years and over, biennial treatment of school age children with albendazole together with schistosomiasis MDA and biannual treatment of pre-school age children through Child Health Days. Assessments were conducted to evaluate the current situation and to determine the treatment strategy for the future.A cross-sectional assessment was conducted in 22 sentinel sites across the country in 2013. In total, 3,514 school age children (1,748 boys and 1,766 girls were examined by the Kato-Katz method. Overall, soil-transmitted helminth prevalence was 1.3% (95% CI: 1.0-1.8% in children examined. Hookworm was the main species detected, with prevalence of 1.2% (95% CI: 0.9-1.6% and mean egg counts of 2.1 epg (95% CI: 0-4.2 epg. Among regions, the Centre Ouest region had the highest hookworm prevalence of 3.4% (95% CI: 1.9-6.1% and mean egg counts of 14.9 epg (95% CI: 3.3-26.6 epg. A separate assessment was conducted in the Centre Nord region in 2014 using community-based cluster survey design during an LF transmission assessment survey (TAS. In this assessment, 351 children aged 6-7 years and 345 children aged 10-14 years were examined, with two cases (0.6% (95% CI: 0.2-2.1% and seven cases (2.0% (95% CI: 1.0-4.1% of hookworm infection was identified respectively. The results using both age groups categorized the region to be 2% to <10% in STH prevalence according to the pre-defined cut-off values.Through large-scale preventive chemotherapy, Burkina Faso has effectively controlled STH in school age children in the country. Research should be conducted on future strategies to consolidate the gain and to interrupt STH transmission in Burkina Faso.

    Full Text Available Abstract Background Systems to exempt the indigent from user fees have been put in place to prevent the worst-off from being excluded from health care services for lack of funds. Yet the implementation of these mechanisms is as rare as the operational research on this topic. This article analyzes an action research project aimed at finding an appropriate solution to make health care accessible to the indigent in a rural district of Burkina Faso. Research This action research project was initiated in 2007 to study the feasibility and effectiveness of a community-based, participative and financially sustainable process for exempting the indigent from user fees. A interdisciplinary team of researchers from Burkina Faso and Canada was mobilized to document this action research project. Results and knowledge sharing The action process was very well received. Indigent selection was effective and strengthened local solidarity, but coverage was reduced by the lack of local financial resources. Furthermore, the indigent have many other needs that cannot be addressed by exemption from user fees. Several knowledge transfer strategies were implemented to share research findings with residents and with local and national decision-makers. Partnership achievements and difficulties Using a mixed and interdisciplinary research approach was critical to grasping the complexity of this community-based process. The adoption of the process and the partnership with local decision-makers were very effective. Therefore, at the instigation of an NGO, four other districts in Burkina Faso and Niger reproduced this experiment. However, national decision-makers showed no interest in this action and still seem unconcerned about finding solutions that promote access to health care for the indigent. Lessons learned The lessons learned with regard to knowledge transfer and partnerships between researchers and associated decision-makers are: i involve potential users of the

A study to measure the efficiency of preventive medical treatments on subsequent reproductive performances of local guinea fowl kept under natural photoperiod in the sub-humid region of Burkina Faso has been conducted. Two groups of 200 day-old guinea chicks each (T1 and T2 have been maintained under controlled conditions of feed, water allowance and more generally habitat (ex: temperature. T1 received no preventive medical treatment while Group T2 was vaccinated against Newcastle disease, and supplemented with a coccidiostatic and a trichomonacid. Percent mortality in T2 was significantly lower than in T1: 21% vs 43% (P < 0.05. In both groups, the livability of chicks with hatching body weights < 25 g at birth was very low (26% and 28% survival in T1 and T2, respectively. No significant differences were observed for body weights between the two groups at 60 weeks of age irrespective of the sex (P < 0.05 in both cases. A comparison of laying rates observed during the entire laying period (May to October indicated a significant difference between T2 and T1 (19 vs 13%, respectively; P < 0.05. The onset of lay was observed at 219 days in T2 but only at 255 days in T1. A general tendency for heavier egg weights in T2 than in T1 was also observed (ex: 40.1 + 3.0 g in T2 vs 38.0 + 1.7 g in T1 at 52 weeks of age, respectively. Our results confirm observations by farmers that the overall reproductive performances of guinea fowl in Burkina Faso is generally very low. The prevention of diseases by a preventive programme improves laying rates and egg weights while significantly decreasing mortality in breeder flocks. The improvement of the average body weight and the laying rate over the season by improved feed, preventive treatments and, possibly, genetic selection of breeder flocks would be of major interest in this

    Full Text Available Technical and socio-economic aspects of transhumance in the soudanian zone of the Bougouriba (Burkina-Faso. The analysis of the situation of the Peul cattle breeders in the Bougouriba valley shows a will of sedentariness which has given rise to a cute sociological problems. Natural forage resources are abundant and of good quality, but are not very accessible due to inercasing land occupation by crops and because of conflicts between herders and farmers. The productivity of sedentary breedings is very low and does not allow modernisation of the traditional agricultural system, while transhumant herds show much better production parametres. The authors suggest that the AVV, a national organism which is responsible for the valley development, should favour sedentariness of Peul breeders and their herds in areas where human occupation is actually low, and should create pastoral reserves where cattle can move freely.

    Full Text Available Abstract Background Sida acuta Burn f. and Sida cordifolia L. (Malvaceae are traditionally used in Burkina Faso to treat several ailments, mainly pains, including abdominal infections and associated diseases. Despite the extensive use of these plants in traditional health care, literature provides little information regarding their toxicity and the pharmacology. This work was therefore designed to investigate the toxicological effects of aqueous acetone extracts of Sida acuta Burn f. and Sida cordifolia L. Furthermore, their analgesic capacity was assessed, in order to assess the efficiency of the traditional use of these two medicinal plants from Burkina Faso. Method For acute toxicity test, mice were injected different doses of each extract by intraperitoneal route and the LD50 values were determined. For the subchronic toxicity evaluation, Wistar albinos rats were treated by gavage during 28 days at different doses of aqueous acetone extracts and then haematological and biochemical parameters were determined. The analgesic effect was evaluated in mice by the acetic-acid writhing test and by the formalin test. Results For the acute toxicity test, the LD50 values of 3.2 g/kg and 3.4 g/kg respectively for S. acuta Burn f. and S. cordifolia L. were obtained. Concerning the haematological and biochemical parameters, data varied widely (increase or decrease according to dose of extracts and weight of rats and did not show clinical correlations. The extracts have produced significant analgesic effects by the acetic acid writhing test and by the hot plate method (p Conclusion The overall results of this study may justify the traditional uses of S. acuta and S. cordifolia .

    The performance of indirect haemagglutination assays (IHA), enzyme-linked immunosorbent assays (ELISA) and indirect immunofluorescent antibody tests (IFAT) were compared with 450 sera from a Schistosoma mansoni-endemic area in Burkina Faso. All participants in this survey provided at least one sample each of stool, urine and serum. From those with an egg-negative Kato-Katz thick smear, a second stool sample was examined. IHA was based on either extracts of adult S. mansoni worms (SmIHA) or S. japonicum egg antigen (SjIHA). For ELISA, three antigen preparations were used, namely: (i) soluble S. mansoni adult worm antigens (SWAP); (ii) soluble S. mansoni egg antigens (SEA); and (iii) a cationic exchange fraction of S. mansoni eggs (CEF6). IFAT was performed with S. mansoni male worm sections. Among the egg-excretors, the sensitivity of ELISA was high and egg antigens performed slightly better (SEA, 96%; CEF6, 97%) than worm antigen (94%). Sensitivity of IHA was satisfactory with homologous (Sm, >85%), but not heterologous (Sj, 56%) parasite antigen. In IFAT, the parenchyma-associated fluorescence showed high sensitivity (95%), but gut-associated fluorescence, which is known to be a sensitive diagnostic marker for schistosome-infected European travelers, was observed only in 76% of a sub-sample of 100 of the endemic sera. Among sera from egg-negative individuals, many gave positive reactions in several or all of the tests employed. These reactions (formally "false positive") are considered to represent true infections, since chemotherapy had not yet been delivered to this population. For the purpose of further surveys in Burkina Faso or other resource-poor settings, we suggest IHA as an accurate diagnostic test and propose to further improve its performance by including egg rather than worm antigens.

    African animal trypanosomosis is a major obstacle to the development of more efficient and sustainable livestock production systems in West Africa. Riverine tsetse species such as Glossina palpalis gambiensis Vanderplank are their major vectors. A wide variety of control tactics is available to manage these vectors, but their elimination will only be sustainable if control is exercised following area-wide integrated pest management (AW-IPM) principles, i.e. the control effort is targeting an entire tsetse population within a circumscribed area. In the present study, genetic variation at microsatellite DNA loci was used to examine the population structure of G. p. gambiensis inhabiting two adjacent river basins, i.e. the Comoé and the Mouhoun River basins in Burkina Faso. A remote sensing analysis revealed that the woodland savannah habitats between the river basins have remained unchanged during the last two decades. In addition, genetic variation was studied in two populations that were separated by a man-made lake originating from a dam built in 1991 on the Comoé. Low genetic differentiation was observed between the samples from the Mouhoun and the Comoé River basins and no differentiation was found between the samples separated by the dam. The data presented indicate that the overall genetic differentiation of G. p. gambiensis populations inhabiting two adjacent river basins in Burkina Faso is low (F(ST)=0.016). The results of this study suggest that either G. p. gambiensis populations from the Mouhoun are not isolated from those of the Comoé, or that the isolation is too recent to be detected. If elimination of the G. p. gambiensis population from the Mouhoun River basin is the selected control strategy, re-invasion from adjacent river basins may need to be prevented by establishing a buffer zone between the Mouhoun and the other river basin(s).

This study uses a linear programming model to estimate economic and environmental impacts of common pastures management policies at village territory level in western Burkina Faso. Results show that considerable economic surplus can be locally released by negotiating taxes for common resources access. The model makes it possible moreover to determine the maximum number of transhumant livestock, which the village territory can accommodate according to the constraint of animal feeding and that of erosion. These indicators can be used to facilitate the assistance with the collective negotiation in the framework of village territory management committees.

    The implementation of cost-recovery and the unequal distribution of health care services between cities and countryside, explain the reduction in health care access in Burkina Faso. To face this context it is necessary to reconsider the manner in which health districts are financed and to reduce the household contribution to a level compatible with the ability to pay for the majority of the population. Without this change, the system will continue to produce serious social inequalities. Patie...

    The integration of field mapping and analytical studies of magmatic units of the northeast of Burkina Faso has provided new information on the tectonic and magmatic evolution of the Oudalan-Gorouol belt and the Gorom-Gorom granitoid terrane. Structural, geochemical and geochronological analyses have helped to clarify the geological evolution of the region during the Tangaean Event (D1) and Eburnean Orogeny (D2) through to the Wabo Tampelse Event (D3). Further to this, zircon U-Pb geochronology data have demonstrated that the Oudalan-Gorouol belt and the Gorom-Gorom granitoid terrane represents some of the oldest outcropping geology in the Palaeoproterozoic Baoulé-Mossi domain recognised to date, with the oldest age at 2253 ± 9 Ma. The geochronology and geology suggests that the basement or a pre-Birimian crust to the Birimian Supergroup may be found in the northeast of Burkina Faso. The Eburnean Orogeny in the northeastern Burkina is preceded by the two phases of deformation (D1-x and D1), and two phases of magmatism. D1-x is associated with the emplacement of the Dori Batholith at the onset of D1 (2164-2141 Ma). D1 ductile-brittle deformation formed F1 folds and discrete high-strained mylonite zones that deformed the Oudalan-Gorouol belt and the Gorom-Gorom granitoid terrane during a southwest-directed palaeo-principal transport direction. The pre-Birimian to Birimian supracrustal rocks and intrusions were regionally metamorphosed during D1 to greenschist to amphibolite facies. The Eburnean Orogeny (2130-1980 Ma) is characterised by northwest-southeast shortening; it was followed by north-northwest to south-southeast shortening with development of sinistral strike-slip faults and shears. D2 brittle-(ductile) deformation is manifested by refolding of F1 by northeast-trending F2, and development of a pervasive northeast-trending S2 to S2-C foliation. Metamorphic grade attained greenschist facies during D2 with development of the mineral assemblage of quartz

Des systèmes de cultures améliorés de niébé ont été introduits dans des exploitations mixtes agriculture-élevage de la zone semi-aride au Burkina Faso et ensuite évalués dans des modèles de programmation linéaire. Les résultats ont montré que les variétés améliorées de niébé associées aux céréales permettent d'accroître la production agricole et le disponible fourrager, et de dégager des revenus pour acheter des compléments de vivriers. L'application de ces systèmes sur les terres de cultures peut varier entre 38% et 64% dans la partie sahélienne. Ils permettent aux agriculteurs de doubler la production de mil et de produire en plus annuellement 353 kg de niébé. Ces systèmes peuvent être promus dans la zone semi-aride du pays sans politique de soutien à la production. Par contre les soles améliorées de cultures pures de niébé ne sont pas profitables en raison des pertes liées au risque climatique, et aussi des coûts de production élevés par rapport aux capacités financières des exploitants. Elles permettent toutefois d'accroître le disponible fourrager à la ferme. Des stratégies de diminution des coûts de production des systèmes améliorés auront un impact considérable sur la sécurité alimentaire et sur le revenu.

    Full Text Available Background: The benefits of universal access to voluntary contraception have been widely documented in terms of maternal and newborn survival, women's empowerment, and human capital. Given population dynamics, the choices and opportunities adolescents have in terms of access to sexual and reproductive health information and services could significantly affect the burden of diseases and nations’ human capital. Objectives: The objectives of this paper are to assess the patterns and trends of modern contraception use among sexually active adolescents by socio-economic characteristics and by birth spacing and parity; to explore predictors of use of modern contraception in relation to the health system; and to discuss implications of the findings for family planning policy and programmes. Design: Data are from the last three Demographic and Health Surveys of Ethiopia, Burkina Faso, and Nigeria. The descriptive analysis focused on sexually active adolescents (15- to 19-year age group, used modern contraception as the dependent variable, and a series of contact points with the health system (antenatal care, institutional delivery, postnatal care, immunisation as covariates. The multivariate analysis used the same covariates, adjusting for socio-economic variables. Results: There are two different groups of sexually active adolescents: those married or in a union with very low use of modern contraception and lower socio-economic status, and those unmarried, among whom nearly 50% are using modern contraception. Younger adolescents have lower modern contraceptive prevalence. There are significant inequality issues in modern contraception use by education, residence, and wealth quintile. However, while there was no significant progress in Burkina Faso and Nigeria, the data in Ethiopia point to a significant and systematic reduction of inequalities. The narrowing of the equity gap was most notable for childbearing adolescents with no education or living

    This study focuses on the potential role of technical and institutional innovations for improving water management in a multi-user context in Burkina Faso. We focus on a system centered on three reservoirs that capture the waters of the Upper Comoé River Basin and servicing a diversity of users, including a sugar manufacturing company, a urban water supply utility, a farmer cooperative, and other downstream users. Due to variable and declining rainfall and expanding users’ needs, drastic fluctuations in water supply and demand occur during each dry season. A decision support tool was developed through participatory research to enable users to assess the impact of alternative release and diversion schedules on deficits faced by each user. The tool is meant to be applied in the context of consultative planning by a local user committee that has been created by a new national integrated water management policy. We contend that both solid science and good governance are instrumental in realizing efficient and equitable water management and adaptation to climate variability and change. But, while modeling tools and negotiation platforms may assist users in managing climate risk, they also introduce additional uncertainties into the deliberative process. It is therefore imperative to understand how these technological and institutional innovations frame water use issues and decisions to ensure that such framing is consistent with the goals of integrated water resource management.

    Land degradation is an environmental problem which weakens agro-sylvo-pastoral productivity in sub-Saharan Africa. The most common manifestation of land degradation is the appearance of denuded land. We carried out an experiment to test the effect of three soil and water conservation techniques on survival and growth of Jatropha curcas seedlings transplanted onto two completely denuded lands in the Sahelian and Sudanian zones of Burkina Faso. We implemented an experimental design with three replicates per restoration technique. A total of 174 seedlings were planted in each study site. The results showed that the soil water content varied according to the restoration technique used (df = 2; F = 53.21; p land in the Sahelian zone. Most of the plants died in the Sahel between April and May, which is the peak of the dry season; this may be an indication that J. curcas may not be as drought-resistant as suggested by the prolific literature which has reported on diverse claims surrounding this plant.

    Full Text Available Abstract Background Vitamin A and zinc are crucial for normal immune function, and may play a synergistic role for reducing the risk of infection including malaria caused by Plasmodium falciparum. Methods A randomized, double-blind, placebo-controlled trial of a single dose of 200 000 IU of vitamin A with daily zinc supplementation was done in children of Sourkoudougou village, Burkina Faso. Children aged from 6 to 72 months were randomized to receive a single dose of 200 000 IU of vitamin A plus 10 mg elemental zinc, six days a week (n = 74 or placebo (n = 74 for a period of six months. Cross-sectional surveys were conducted at the beginning and the end of the study, and children were evaluated daily for fever. Microscopic examination of blood smear was done in the case of fever (temperature ≥37.5°C for malaria parasite detection. Results At the end of the study we observed a significant decrease in the prevalence malaria in the supplemented group (34% compared to the placebo group (3.5% (p Conclusion These results suggest that combined vitamin A plus zinc supplementation reduces the risk of fever and clinical malaria episodes among children, and thus may play a key role in malaria control strategies for children in Africa.

    Cercariae and adult Schistosoma mansoni were used to prepare, respectively, cercarial secretions (CS) and worm vomit (WoV). These were used as antigens in an enzyme-linked immunosorbent assay (ELISA) to test the IgG-reactivity of sera obtained in an S. mansoni-endemic area of Burkina Faso. Among the egg-excreting individuals (n = 240), 94.6% reacted positively with WoV, but only 62.9% with CS, thus suggesting a high diagnostic sensitivity of WoV, but not of CS. Among those individuals without detectable eggs in two Kato-Katz thick smears from different stool specimens (n = 215), the respective percentages of positive IgG reactivity were 78.1% and 63.3%. These positive reactions in the absence of detectable eggs are interpreted in terms of limited sensitivity of parasitological stool examinations. Optical density values in ELISA with CS, but not with WoV, correlated negatively with age, which may reflect decreasing exposure to cercariae in older individuals. PMID:16469168

    Full Text Available The use of mathematical modeling as a tool for decision support is not common in Africa in solving development problems. In this article we talk about the numerical simulation of groundwater level of the plain of Gondo (Burkina Faso and the sensitivity analysis of the hydrodynamic parameters. The domain has fractures which have hydraulic coefficients lower than those of the rock. Our contribution is to bring brief replies to the real problem posed in the thesis of Mr. KOUSSOUBE [1]. Namely that what causes the appearance of the piezometric level observed and impact of surface water on the piezometry. The mathematical model of the flow was solved by programming the finite element method on FreeFem++[2]. A local refinement of the mesh at fracture was used. We then conduct a sensitivity analysis to see which hydrodynamic parameters influences much of the solution. The method used for the sensitivity analysis is based on the calculation of the gradient by the adjoint equation and requires great computational power. To remedy this, we used a technique of distributed computing and we launched our application to the Moroccan grid (magrid. This allowed us to reduce the computation time. The results allowed to highlight the role of fractures and contributions of surface water on the evolution of the piezometric level of the plain of Gondo and identified the parameters that greatly influence the piezometric level.

    With the exception of target site mutations, insecticide resistance mechanisms in the principle malaria vector Anopheles gambiae, remains largely uncharacterized in Burkina Faso. Here we detected high prevalence of resistance in Vallée du Kou (VK) to pyrethroids, DDT and dieldrin, moderate level for carbamates and full susceptibility to organophosphates. High frequencies of L1014F kdr (75%) and Rdl (87%) mutations were observed showing strong correlation with pyrethroids/DDT and dieldrin resistance. The frequency of ace1R mutation was low even in carbamate resistant mosquitoes. Microarray analysis identified genes significantly over-transcribed in VK. These include the cytochrome P450 genes, CYP6P3 and CYP6Z2, previously associated with pyrethroid resistance. Gene Ontology (GO) enrichment analysis suggested that elevated neurotransmitter activity is associated with resistance, with the over-transcription of target site resistance genes such as acetylcholinesterase and the GABA receptor. A rhodopsin receptor gene previously associated with pyrethroid resistance in Culex pipiens pallens was also over-transcribed in VK. This study highlights the complex network of mechanisms conferring multiple resistance in malaria vectors and such information should be taken into account when designing and implementing resistance control strategies.

    Full Text Available An entomological survey was carried out at 15 sites dispersed throughout the three eco-climatic regions of Burkina Faso (West Africa in order to assess the current distribution and frequency of mutations that confer resistance to insecticides in An. gambiae s.l. populations in the country. Both knockdown (kdr resistance mutation variants (L1014F and L1014S, that confer resistance to pyrethroid insecticides, were identified concomitant with the ace-1 G119S mutation confirming the presence of multiple resistance mechanisms in the An. gambiae complex in Burkina Faso. Compared to the last survey, the frequency of the L1014F kdr mutation appears to have remained largely stable and relatively high in all species. In contrast, the distribution and frequency of the L1014S mutation has increased significantly in An. gambiae s.l. across much of the country. Furthermore we report, for the first time, the identification of the ace.1 G119S mutation in An. arabiensis populations collected at 8 sites [corrected]. This mutation, which confers resistance to organophosphate and carbamate insecticides, has been reported previously only in the An. gambiae S and M molecular forms. This finding is significant as organophosphates and carbamates are used in indoor residual sprays (IRS to control malaria vectors as complementary strategies to the use of pyrethroid impregnated bednets. The occurrence of the three target-site resistance mutations in both An. gambiae molecular forms and now An. arabiensis has significant implications for the control of malaria vector populations in Burkina Faso and for resistance management strategies based on the rotation of insecticides with different modes of action.

    In this work we present the rationale and the first results of a Cosmo-SkyMed AO project devoted to use high resolution synthetic aperture radar data for water resource management in semi-arid regions. A case study was developed in Burkina Faso, one of the poorest countries of the world, where almost 80% of the population lives in rural areas depending from agriculture and livestock. It is characterized by the alternation of a rainy (3 months) and a dry (9 months) season, with extreme climate conditions (drought and floods). The project was approved by the Italian Space Agency, that provided Cosmo SkyMed Stripmap (3m resolution) and Spotligth (1m resolution) SAR images. The study area is in the northern part of Burkina Faso around the village of Bidi. A first study is related on the identification of eroded areas, which are indicative of desertification processes. Eroded soils are no more able to absorb and drain water, so that their humidity and, as a consequence, their dielectric constant and conductivity are almost independent by the precipitation. By comparing SAR images acquired during the rainy and the dry seasons, the eroded soils do not change their reflectivity and they can be identified by change detection techniques. In this work we employ innovative fractal change detection techniques, based on the image spectrum evaluation and the comparison of the fractal dimension. As the precipitations occur only during three months, it is crucial to collect water in the rainy season, by the means of artificial basins, in order to irrigate the fields in the dry season. The construction of little artificial basins is usually carried out under the initiative of small associations of farmers. The location, design and management of the basins sometimes is not rational, for the lack of all the information needed for the design. The best location for the construction of a new artificial basin depends on the total volume of surface water that may be collected in one year

    2012-04-01

    Full Text Available Abstract Background There is accumulating evidence that host heparan sulphate proteoglycans play an important role in the life cycle of Plasmodium through their heparan sulphate chains, suggesting that genetic variations in genes involved in heparan sulphate biosynthesis may influence parasitaemia. Interestingly, Hs3st3a1 and Hs3st3b1 encoding enzymes involved in the biosynthesis of heparan sulphate are located within a chromosomal region linked to Plasmodium chabaudi parasitaemia in mice. This suggests that HS3ST3A1 and HS3ST3B1 may influence P. falciparum parasitaemia in humans. Methods Polymorphisms within HS3ST3A1 and HS3ST3B1 were identified in 270 individuals belonging to 44 pedigrees and living in Burkina Faso. Linkage and association between parasitaemia and the polymorphisms were assessed with MERLIN and FBAT. A genetic interaction analysis was also conducted based on the PGMDR approach. Results Linkage between P. falciparum parasitaemia and the chromosomal region containing HS3ST3A1 and HS3ST3B1 was detected on the basis of the 20 SNPs identified. In addition, rs28470223 located within the promoter of HS3ST3A1 was associated with P. falciparum parasitaemia, whereas the PGMDR analysis revealed a genetic interaction between HS3ST3A1 and HS3ST3B1. Seventy-three significant multi-locus models were identified after correcting for multiple tests; 37 significant multi-locus models included rs28470223, whereas 38 multi-locus models contained at least one mis-sense mutation within HS3ST3B1. Conclusion Genetic variants of HS3ST3A1 and HS3ST3B1 are associated with P. falciparum parasitaemia. This suggests that those variants alter both the function of heparan sulphate proteoglycans and P. falciparum parasitaemia.

    2012-09-01

    Full Text Available Abstract Background HBB, IL4, IL12, TNF, LTA, NCR3 and FCGR2A polymorphisms have been associated with malaria resistance in humans, whereas cytophilic immunoglobulin G (IgG antibodies are thought to play a critical role in immune protection against asexual blood stages of the parasite. Furthermore, HBB, IL4, TNF, and FCGR2A have been associated with both malaria resistance and IgG levels. This suggests that some malaria resistance genes influence the levels of IgG subclass antibodies. Methods In this study, the effect of HBB, IL4, IL12, TNF, LTA, NCR3 and FCGR2A polymorphisms on the levels of IgG responses against Plasmodium falciparum blood-stage extract was investigated in 220 individuals living in Burkina Faso. The Pearson’s correlation coefficient among IgG subclasses was determined. A family-based approach was used to assess the association of polymorphisms with anti-P. falciparum IgG, IgG1, IgG2, IgG3 and IgG4 levels. Results After applying a multiple test correction, several polymorphisms were associated with IgG subclass or IgG levels. There was an association of i haemoglobin C with IgG levels; ii the FcγRIIa H/R131 with IgG2 and IgG3 levels; iii TNF-863 with IgG3 levels; iv TNF-857 with IgG levels; and, v TNF1304 with IgG3, IgG4, and IgG levels. Conclusion Taken together, the results support the hypothesis that some polymorphisms affect malaria resistance through their effect on the acquired immune response, and pave the way towards further comprehension of genetic control of an individual’s humoral response against malaria.

    Soil erosion is currently menacing the availability of arable land in various countries worldwide. In particular the countries located in the Sahel area of Sub-Saharan Africa are extremely prone to this type of environmental degradation. The same countries rely traditionally upon subsistence farming, which makes the population more vulnerable to environmental changes. The study here presented exploits remote sensed data for identifying the main degradation processes occurring in a small catchment of central Burkina Faso (i.e., Boulbi watershed). This catchment, approximately 100 square km large, is characterized by the presence of a 30 years old dam, whose reservoir feeds 80 ha of rice-fields. This produce contributes up to 13% of the regional rice production. Nonetheless other crops, along with rain-fed rice, are grown all across the Boulbi catchment during the rainy season. Both the increasing gully erosion and the urbanization of the capital city pushing from the North are significantly threatening the farming activities. By using aerial frames acquired with a 16 years' time interval (i.e., 1996, 2012), free satellite imagery, and field surveys, the base cartography of the investigated area was updated and the most active gullies were identified. Moreover a change detection analysis was performed on both artifacts and land use features. More than 200.000 square m of erosion areas and an increase of nearly 90% in built-up areas were detected. In addition, the importance of producing up-to-date base data was proven by the exploitation of the outcomes for the production of a catchment land and water management plan.

    Full Text Available INTRODUCTION: To design effective national diarrhea control programs, including oral rehydration solution (ORS and therapeutic zinc supplementation, information is needed on local perceptions of illness, external care seeking behaviors, and home treatment practices. METHODS: A cross-sectional, community-based household survey was conducted in the Orodara Health District, Burkina Faso. Caregivers of 10,490 children <27 months were interviewed to assess child diarrhea prevalence and related care practices. Characteristics of households, caregivers, children, and reported illnesses were compared for those caregivers who did or did not recognize the presence of diarrhea, as defined according to clinical criteria (≥ 3 liquid or semi-liquid stools/day. Multiple logistic regression models were used to examine factors associated with illness recognition and treatment. RESULTS: Clinically defined diarrhea was present in 7.6% (95% CI: 7.1-8.1% of children during the 24 hours preceding the survey but recognized by only 55% of caregivers. Over half (55% of the caregivers of 1,067 children with a clinically defined diarrhea episode in the past 14 days sought care outside the home; 78% of those seeking care attended a public sector clinic. Care was sought and treatment provided more frequently for children with fever, vomiting, anorexia, longer illness duration, and those living closer to the health center; and care was sought more frequently for male children. 80% of children with recent diarrhea received some form of treatment; only 24% received ORS, whereas 14% received antibiotics. Zinc was not yet available in the study area. CONCLUSIONS: Caregivers frequently fail to recognize children's diarrhea, especially among younger infants and when illness signs are less severe. Treatment practices do not correspond with international recommendations in most cases, even when caregivers consult with formal health services. Child caregivers need additional

    Introduction Transgender women are at high risk for the acquisition and transmission of HIV. However, there are limited empiric data characterizing HIV-related risks among transgender women in sub-Saharan Africa. The objective of these analyses is to determine what factors, including sexual behaviour stigma, condom use and engagement in sex work, contribute to risk for HIV infection among transgender women across three West African nations. Methods Data were collected via respondent-driven sampling from men who have sex with men (MSM) and transgender women during three- to five-month intervals from December 2012 to October 2015 across a total of six study sites in Togo, Burkina Faso and Côte d'Ivoire. During the study visit, participants completed a questionnaire and were tested for HIV. Chi-square tests were used to compare the prevalence of variables of interest between transgender women and MSM. A multilevel generalized structural equation model (GSEM) was used to account for clustering of observations within study sites in the multivariable analysis, as well as to estimate mediated associations between sexual behaviour stigma and HIV infection among transgender women. Results In total, 2456 participants meeting eligibility criteria were recruited, of which 453 individuals identified as being female/transgender. Transgender women were more likely than MSM to report selling sex to a male partner within the past 12 months (ptransgender women have distinct behaviours from those of MSM and that stigma perpetuated against transgender women is impacting HIV-related behaviours. Furthermore, given these differences, interventions developed for MSM will likely be less effective among transgender women. This situation necessitates dedicated responses for this population, which has been underserved in the context of both HIV surveillance and existing responses. PMID:27431465

    Full Text Available BACKGROUND: The private medical care sector is expanding in urban cities in Sub-Saharan Africa (SSA. However, people's health-care-seeking behaviors in this new landscape remain poorly understood; furthermore, distinguishing between public and private providers and among various types of private providers is critical in this investigation. This study assessed, by type, the healthcare providers urban residents in Burkina Faso visit, and their choice determinants. METHOD: We conducted a population-based survey of a representative sample of 1,600 households in Ouagadougou from July to November 2011, consisting of 5,820 adults. We assessed the types of providers people typically sought for severe and non-severe conditions. We applied generalized estimating equations in this study. RESULTS: Among those surveyed, 97.7% and 53.1% indicated that they seek a formal provider for treating severe and non-severe conditions, respectively. Among the formal provider seekers, 20.5% and 17.0% chose for-profit (FP providers for treating severe and non-severe conditions, respectively. Insurance coverage was held by 2.0% of those surveyed. Possessing insurance was the strongest predictor for seeking FP, for both severe (odds ratio [OR]  = 1.15, 95% confidence interval [CI] = 1.04-1.28, and non-severe conditions (OR = 1.22, 95% CI = 1.07-1.39. Other predictors included being a formal jobholder and holding a higher level education. By contrast, we observed no significant difference in predisposing, enabling, or need characteristics between not-for-profit (NFP provider seekers and public provider seekers. Proximity was the primary reason for choosing a provider. CONCLUSION: The results suggested that FP providers play a crucial role in the urban healthcare market in SSA. Socioeconomic status and insurance status are significant predictors of provider choice. The findings can serve as a crucial reference for policymakers in response to the emergence of FP providers

    Full Text Available Abstract Background A prospective study aiming at assessing the effect of adding a third dose sulphadoxine-pyrimethamine (SP to the standard two-dose intermittent preventive treatment for pregnant women was carried out in Hounde, Burkina Faso, between March 2006 and July 2008. Pregnant women were identified as earlier as possible during pregnancy through a network of home visitors, referred to the health facilities for inclusion and followed up until delivery. Methods Study participants were enrolled at antenatal care (ANC visits and randomized to receive either two or three doses of SP at the appropriate time. Women were visited daily and a blood slide was collected when there was fever (body temperature > 37.5°C or history of fever. Women were encouraged to attend ANC and deliver in the health centre, where the new-born was examined and weighed. The timing and frequency of malaria infection was analysed in relation to the risk of low birth weight, maternal anaemia and perinatal mortality. Results Data on birth weight and haemoglobin were available for 1,034 women. The incidence of malaria infections was significantly lower in women having received three instead of two doses of SP. Occurrence of first malaria infection during the first or second trimester was associated with a higher risk of low birth weight: incidence rate ratios of 3.56 (p p = 0.034, respectively. After adjusting for possible confounding factors, the risk remained significantly higher for the infection in the first trimester of pregnancy (adjusted incidence rate ratio = 2.07, p = 0.002. The risk of maternal anaemia and perinatal mortality was not associated with the timing of first malaria infection. Conclusion Malaria infection during first trimester of pregnancy is associated to a higher risk of low birth weight. Women should be encouraged to use long-lasting insecticidal nets before and throughout their pregnancy.

    Full Text Available Abstract Background User fees were generalized in Burkina Faso in the 1990 s. At the time of their implementation, it was envisioned that measures would be instituted to exempt the poor from paying these fees. However, in practice, the identification of indigents is ineffective, and so they do not have access to care. Thus, a community-based process for selecting indigents for user fees exemption was tested in a district. In each of the 124 villages in the catchment areas of ten health centres, village committees proposed lists of indigents that were then validated by the health centres' management committees. The objective of this study is to evaluate the effectiveness of this community-based selection. Methods An indigent-selection process is judged effective if it minimizes inclusion biases and exclusion biases. The study compares the levels of poverty and of vulnerability of indigents selected by the management committees (n = 184 with: 1 indigents selected in the villages but not retained by these committees (n = 48; ii indigents selected by the health centre nurses (n = 82; and iii a sample of the rural population (n = 5,900. Results The households in which the three groups of indigents lived appeared to be more vulnerable and poorer than the reference rural households. Indigents selected by the management committees and the nurses were very comparable in terms of levels of vulnerability, but the former were more vulnerable socially. The majority of indigents proposed by the village committees who lived in extremely poor households were retained by the management committees. Only 0.36% of the population living below the poverty threshold and less than 1% of the extremely poor population were selected. Conclusions The community-based process minimized inclusion biases, as the people selected were poorer and more vulnerable than the rest of the population. However, there were significant exclusion biases; the selection was very restrictive

  15. Revisiting plant conservation on wooded shrines by a transversal approach: "Core" vs. "satellite" species and anthropological knowledge in Bwaba land, Burkina Faso

    Full Text Available Studies on plant conservation in sacred groves provide mixed results, with some showing their effectiveness while others do not. We argue that beyond the variety of field cases, studies usually suffer from overrating rare species and insufficient consideration of societal data. The sacred sites of Bondoukuy department in Bwaba cultural area (Burkina Faso were geo-referenced and measured; the most abundant ligneous species were listed and their abundance recorded. Their conservation status and dynamics were assessed based on the core vs. satellite species model of Hanski. Data interpretations relied on the phytogeographical affinities of abundant species and on anthropological knowledge of the Bwaba society. The vast majority of shrines were less than 1 ha, located in or near villages in specific landscape features, and covered with trees. The most abundant species of shrines belonged mostly to local phytochories, but were subject to rather high anthropisation. The results support the concept that wooded shrines preserve local biodiversity, but indicate threats from an invasive alien species. The location and condition of shrines appeared to be constitutive features: the Bwaba system of thought involves a series of sacred sites (with and without trees located in remarkable features of the landscape, and their way of life has resulted in the proximity of these sites to the villages. The beliefs that promote plant cover conservation do so only to a certain extent and regardless of the species content, which raises the concern that alien species may upset the established communities. These beliefs have led the Bwaba to choose the most humid environments in which to set up their wooded shrines, which is interesting from a conservation perspective. The study advocates for a better consideration of social data to identify the key elements of the dynamics of the vegetation of sacred groves.

    Food insecurity negatively impacts outcomes in adults and children including parenting practices, child development, educational achievement, school performance, diet, and nutritional status. Ethnographic and quantitative research suggests that food insecurity affects well-being not only through the lack food, poor diet, and hunger, but also through social and psychological consequences that are closely linked to it. These studies are limited in number, and have mostly been carried out in contexts with market economies where household access to food depends almost solely on income. This study considers the social and psychological experiences closely linked to food insecurity in northern Burkina Faso, a context marked by subsistence farming, chronic food insecurity with a strong seasonal pattern, and a complex social structure. A total of 33 men and women from ten households were interviewed in February 2001 using semi-structured interview guides. Data were analyzed following the principles of thematic analysis. Food insecurity is closely linked with consequences such as concern, worries, and anxiety that ultimately lead to weight and sleep loss. Food insecurity results in feelings of alienation (e.g., shame) and deprivation (e.g., guilt), and alters household cohesion leading to disputes and difficulties keeping children at home. Decisions made by household members to manage and cope with food insecurity are shaped by their fear of alienation and other cultural and social norms. These findings, although derived from data collected 10 years ago before the 2008 food and fuel crises, remain valid in the study context, and emphasize the importance of social and psychological consequences closely linked to food insecurity and their negative impact on the well-being at both individual and household levels in contexts of non-market economy and chronic food insecurity. Attention to these non-nutritional consequences will improve the design, implementation, and evaluation

    In sub-Saharan Africa, various studies have been conducted on severe disability in activities of daily living, instrumental or domestic activities. These studies have reported different rates without describing the social context for understanding their results. This study was conducted in Burkina Faso to fill the gaps in scientific information on disability in these areas. We conducted a cross-sectional descriptive study in Bobo-Dioulasso among the older population, aged 60 and above. Their functional status was evaluated using the Functional Autonomy Measurement System (SMAF). Data analysis was done with the help of Stata. A systematic random sample of 351 aging adults was interviewed. Moderate to severe functional disability or the need for supervision or assistance was present in 7% in activities of daily living and 86% in instrumental or domestic activities of daily living. This need for assistance varied according to the different activities or items in each domain. The proportions of disability found in this study are higher than those of previous studies that measured the often severe disabilities. All persons with disability claimed to have stable human resources which help them to manage their disabilities. The social context instrumental or domestic activities of daily living are divided by generation and/or by sex. That explains some results. With this division, it's inacceptable in some family that elders and/or old men do instrumental or domestic activities of daily living as prepare meals, do laundry, carry water to wash. The variation of this division from one family to another complicates the assessment of functional disability. To best manage elders disabilities, strategies must develop to: 1) retard the resignation of the family in care of its elderly in functional disability, 2) anticipate the preparation of formal social networks, public structures to support the elderly.

    Full Text Available Background: Malnutrition is still prevalent worldwide, and its severity, which differs between regions and countries, has led to international organisations proposing its inclusion in the global development framework that will succeed the Millennium Development Goals (post-2015 framework. In Sub-Saharan Africa, malnutrition is particularly severe, among women and children under 5 years. The prevalence of malnutrition has been reported worldwide, differing from region to region and country to country. Nevertheless, little is known about how malnutrition differs between multiple locations along an urban–rural continuum. Objective: A survey was carried out in and around Ouagadougou, Burkina Faso, between August and September 2014 to map household nutrition insecurity along the urban–rural continuum, using a transect approach to guide the data collection. Design: Transects of 70 km long and 2 km wide directed radially from the city centre outwards were laid, and data were collected from randomly selected households along these transects. Women's dietary diversity scores (WDDSs were calculated from a sample of 179 women of reproductive age (15–49 years from randomly selected households. Additionally, anthropometric data (height/length and weight of 133 children under 5 years of age were collected along the same transects for the computation of anthropometric indices. Results: We found that relative proportions of the nutrition indices such as stunting, wasting and underweight varied across the urban–rural continuum. Rural households (15% had the highest relative proportion of WDDS compared with urban households (11% and periurban households (8%. There was a significant association between children under 5 years’ nutritional status (wasting, stunting and underweight and spatial location (p=0.023. The level of agricultural activities is a possible indicator of wasting in children aged 6–59 months (p=0.032. Conclusion: Childhood

    Recent results from the phase 3 trial of RTS,S/AS01 malaria vaccine show that the vaccine induced partial protection against clinical malaria in infants and children; given the high burden of the disease it is currently considered for use in malaria endemic countries. To inform adoption decisions the paper proposes a generalizable methodology to estimate the cost of vaccine introduction using routinely collected and publicly available data from the cMYP, UNICEF, and WHO-CHOICE. Costing is carried out around a set of generic activities, assumptions, and inputs for delivery of immunization services adapted to a given country and deployment modality to capture among other factors the structure of the EPI program, distribution model, geography, and demographics particular to the setting. The methodology is applied to estimate the cost of RTS,S introduction in Burkina Faso, Ghana, Kenya, Senegal, Tanzania, and Uganda. At an assumed vaccine price of $5 per dose and given our assumptions on coverage and deployment strategy, we estimate total economic program costs for a 6-9 months cohort within $23.11-$28.28 per fully vaccinated child across the 6 countries. Net of procurement, costs at country level are substantial; for instance in Tanzania these could add as much as $4.2 million per year or an additional $2.4 per infant depending on the level of spare capacity in the system. Differences in cost of vaccine introduction across countries are primarily driven by differences in cost of labour. Overall estimates generated with the methodology result in costs within the ranges reported for other new vaccines introduced in SSA and capture multiple sources of heterogeneity in costs across countries. Further validation with data from field trials will support use of the methodology while also serving as a validation for cMYP and WHO-CHOICE as resources for costing health interventions in the region.

    Accumulating evidence indicates that health crises can play a key role in precipitating or exacerbating poverty. For women of reproductive age in low-income countries, the complications of pregnancy are a common cause of acute health crisis, yet investigation of longer-term dynamics set in motion by such events, and their interactions with other aspects of social life, is rare. This article presents findings from longitudinal qualitative research conducted in Burkina Faso over 2004-2010. Guided by an analytic focus on patterns of continuity and change, and drawing on recent discussions on the notion of 'resilience', and the concepts of 'social capital' and 'bodily capital', we explore the trajectories of 16 women in the aftermath of costly acute healthcare episodes. The synthesis of case studies shows that, in conditions of structural inequity and great insecurity, an individual's social capital ebbs and flow over time, resulting in a trajectory of multiple adaptations. Women's capacity to harness or exploit bodily capital in its various forms (beauty, youthfulness, physical strength, fertility) to some extent determines their ability to confront and overcome adversities. With this, they are able to further mobilise social capital without incurring excessive debt, or to access and accumulate significant new social capital. Temporary self-displacement, often to the parental home, is also used as a weapon of negotiation in intra-household conflict and to remind others of the value of one's productive and domestic labour. Conversely, diminished bodily capital due to the physiological impact of an obstetric event or its complications can lead to reduced opportunities, and to further disadvantage. PMID:23063215

    The Sahelian countries are increasingly affected by lack of water, soil erosion, desertification and loss of biodiversity. Land and water resources are currently facing an overwhelming pressure due to population growth and to a significant decrease in rainfall rates since the 1970s. Nevertheless, the decrease of the number of rainy days did not affect neither rainfall aggressiveness nor daily rainfall extreme values. Rill and gully erosion, the progressive disappearance of the vegetation and the extension of soil surface crusting result in the reduction of soil thickness, the decrease of nutrients holding capability and water storage loss. To cope with these issues, Soil and Water Conservation (SWC) works have been highly employed in the Sahelian area. However, a proper cost-effectiveness analysis of these interventions at catchment scale requires a quantitative survey on erosion and sedimentation processes, which is expensive and time-consuming. Where data for calibration and validation of process-based models are scarce, a synthetic method to evaluate the economical sustainability of a proposed intervention could be of paramount importance. Referring to a field data collection and to a literature survey, the study herein proposed aims to assess the effectiveness of SWC measures, employed to limit soil erosion and reservoir siltation. Using the Laaba watershed (Northern Burkina Faso, Department of Koumbri) as a case study, the catchment sediment budget is estimated by means of topographical, pedologic and land use parameters and the sedimentation rates of the reservoir and the SWC works. Finally, a cost-effectiveness analysis is performed to assess the economical sustainability of SWC interventions. Although not intended to be quantitative at a local scale, the proposed methodology can be easily implemented for land and water management to prioritize the areas of intervention when data and financial resources are limited, and it is beneficial where the application

    We study the geography of schistosomiasis across Burkina Faso by means of a spatially explicit model of water-based disease dynamics. The model quantitatively addresses the geographic stratification of disease burden in a novel framework by explicitly accounting for drivers and controls of the disease, including spatial information on the distributions of population and infrastructure, jointly with a general description of human mobility and climatic/ecological drivers. Spatial patterns of disease are analysed by the extraction and the mapping of suitable eigenvectors of the Jacobian matrix subsuming the stability of the disease-free equilibrium. The relevance of the work lies in the novel mapping of disease burden, a byproduct of the parametrization induced by regional upscaling, by model-guided field validations and in the predictive scenarios allowed by exploiting the range of possible parameters and processes. Human mobility is found to be a primary control at regional scales both for pathogen invasion success and the overall distribution of disease burden. The effects of water resources development highlighted by systematic reviews are accounted for by the average distances of human settlements from water bodies that are habitats for the parasite's intermediate host. Our results confirm the empirical findings about the role of water resources development on disease spread into regions previously nearly disease-free also by inspection of empirical prevalence patterns. We conclude that while the model still needs refinements based on field and epidemiological evidence, the proposed framework provides a powerful tool for large-scale public health planning and schistosomiasis management.

    Full Text Available Accurate quantification of land use/cover change (LULCC is important for efficient environmental management, especially in regions that are extremely affected by climate variability and continuous population growth such as West Africa. In this context, accurate LULC classification and statistically sound change area estimates are essential for a better understanding of LULCC processes. This study aimed at comparing mono-temporal and multi-temporal LULC classifications as well as their combination with ancillary data and to determine LULCC across the heterogeneous landscape of southwest Burkina Faso using accurate classification results. Landsat data (1999, 2006 and 2011 and ancillary data served as input features for the random forest classifier algorithm. Five LULC classes were identified: woodland, mixed vegetation, bare surface, water and agricultural area. A reference database was established using different sources including high-resolution images, aerial photo and field data. LULCC and LULC classification accuracies, area and area uncertainty were computed based on the method of adjusted error matrices. The results revealed that multi-temporal classification significantly outperformed those solely based on mono-temporal data in the study area. However, combining mono-temporal imagery and ancillary data for LULC classification had the same accuracy level as multi-temporal classification which is an indication that this combination is an efficient alternative to multi-temporal classification in the study region, where cloud free images are rare. The LULCC map obtained had an overall accuracy of 92%. Natural vegetation loss was estimated to be 17.9% ± 2.5% between 1999 and 2011. The study area experienced an increase in agricultural area and bare surface at the expense of woodland and mixed vegetation, which attests to the ongoing deforestation. These results can serve as means of regional and global land cover products validation, as they

    Full Text Available Introduction: Despite many prevention efforts, the number of children infected by HIV in sub-Saharan Africa through vertical transmission remains high. This infection can be reduced through programmes of prevention of mother-to-child HIV transmission (PMTCT. The objective of this study was to evaluate the effectiveness of the PMTCT protocol at Saint Camille Medical Centre in Ouagadougou, Burkina Faso. Methods: From August 2012 to September 2013, samples of dried blood spot (DBS were collected from 160 children aged 6 weeks born to HIV-1 positive mothers who were under PMTCT protocol at Saint Camille Medical Centre and 40 children of the same age group from orphanages and whose mothers were dead or unknown. The samples were tested using the Abbott Real Time HIV-1 Qualitative kit. The clinical data of mothers were collected and analyzed using SPSS Version 17.0 and Epi Info Version 6.0 softwares. Results: Among pregnant women in this study, 52.5% were predominantly young (24–29 years and 60.62% were housewives. In total, 50.5% (101/200 were in combination of AZT/3TC/NVP and 29.5% (59/200 were on prophylaxis (AZT/3TC. The rate of vertical transmission of HIV-1 was 0.0% (p<0.001 in children whose mothers were taking a combination of AZT/3TC/NVP (0/101 or were on a prophylaxis AZT/3TC treatment (0 /59. The rate of HIV-1 transmission in orphaned children was 15.0% (6/40. Conclusions: The PMTCT protocol is effective and reduces very significantly (p<0.001 the risk of transmission of HIV-1 from mother to child. In addition, screening by PCR of orphaned children vertically infected with HIV, enabled them to receive an early treatment.

    Background Safe, effective and affordable drug combinations against falciparum malaria are urgently needed for the poor populations in malaria endemic countries. Methylene blue (MB) combined with chloroquine (CQ) has been considered as one promising new regimen. Objectives The primary objective of this study was to evaluate the safety of CQ-MB in African children with uncomplicated falciparum malaria. Secondary objectives were to assess the efficacy and the acceptance of CQ-MB in a rural population of West Africa. Methods In this hospital-based randomized controlled trial, 226 children (6–59 months) with uncomplicated falciparum malaria were treated in Burkina Faso. The children were 4:1 randomized to CQ-MB (n = 181; 25 mg/kg CQ and 12 mg/kg MB over three days) or CQ (n = 45; 25 mg/kg over three days) respectively. The primary outcome was the incidence of severe haemolysis or other serious adverse events (SAEs). Efficacy outcomes were defined according to the WHO 2003 classification system. Patients were hospitalized for four days and followed up until day 14. Results No differences in the incidence of SAEs and other adverse events were observed between children treated with CQ-MB (including 24 cases of G6PD deficiency) compared to children treated with CQ. There was no case of severe haemolysis and also no significant difference in mean haemoglobin between study groups. Treatment failure rates were 53.7% (95% CI [37.4%; 69.3%]) in the CQ group compared to 44.0% (95% CI [36.3%; 51.9%]) in the CQ-MB group. Conclusion MB is safe for the treatment of uncomplicated falciparum malaria, even in G6PD deficient African children. However, the efficacy of the CQ-MB combination has not been sufficient at the MB dose used in this study. Future studies need to assess the efficacy of MB at higher doses and in combination with appropriate partner drugs. PMID:16179085

Sur base d’une étude de terrain menée au Burkina Faso en 2012, cet article vise à cerner les mutations induites par les commentaires des internautes postés sur les sites des médias en ligne. Ces mutations concernent la pratique professionnelle des journalistes, qui se trouve interrogée par les avis et interpellations des internautes, les modalités de la participation citoyenne et même les usages du pouvoir politique. Les journalistes et les pouvoirs publics sont de plus en plus attentifs à cette participation en ligne, comme en témoignent les rappels à l’ordre réguliers de l’instance de régulation de la communication qui en supervise les contenus. Dans les rédactions de presse écrite, les commentaires postés par les internautes sur le site du journal sont valorisés jusqu’à se trouver repris en titre à la Une de l’édition papier. Et, dans les cénacles politiques, les débats en ligne ont même pu influencer certaines prises de décisions, dans un contexte social et sécuritaire très sensible. Après un bref aperçu de la presse burkinabè en ligne, cet article décrit les dynamiques professionnelles, politiques et sociales liées à l’émergence de cette forme d’expression participative, qui poussent à s’interroger sur la nature et la vocation du journalisme d’information et la place de la liberté d’expression dans ce pays d’Afrique subsaharienne.  Web user contribution to news sites in Europe and North America has already been the subject of much research (Degand & Simonson 2011, Falguères 2008, Paulussen & Ugille 2008, Rebillard & Touboul 2010, Calabrese 2014.

    Full Text Available Analysis of the Determinants of Households'Fish Demand in Burkina Faso: the Case of a Rural Area (Vallée du Kou and Urban Areas (Bobo-Dioulasso and Ouagadougou. A study was conducted in 2004 in Burkina Faso in order to analyze the determinants of households' fish demand in both rural (Vallée du Kou and urban (Bobo-Dioulasso and Ouagadougou areas. To achieve this objective, 535 households were surveyed, the data collected were analyzed and a double-log regression function was constructed. The results of this study showed that households' fish consumption varied considerably according to the area (rural or urban. Households' fish demand was influenced by the availability of the product in the market. In addition to that, when the fish supply frequency increased, the duration of the conservation of the product was reduced or was annulled. The study revealed that the determinants of fish demand in rural area in Vallée du Kou included the size of the household, the prize of the fish in the market, the level of education and the revenue of the head of the household. In urban areas, these determinants include mainly the revenue of the head of the household, fish supply frequency, and conservation methods of the product.

    Full Text Available Improvement of Organic Status in Tropical Ferruginous Soil under Andropogon spp. Fallow (Burkina Faso: Treatment Effects on Soil Chemical Elements. Among the soils of the Sudanian zone, the ferruginous types are the most common and are characterized by low levels of productivity. The quality of these soils decreases further because of the shortening of the fallow duration and the mining type of cultivation. The trial carried out at Sobaka, in the Sudanian zone of Burkina Faso was designed to study palliative solutions to the yield reductions consecutive to the decrease in ferruginous soil fertility. An artifi cial prairie based on Andropogon spp. was created and allowed to stand fallow for 3-years to monitor the evolution of chemical constituents of the soil. The objectives were to obtain rapid improvement of the bio-physico-chemical properties of the soils and to permit a shortening of the fallow duration. Total carbon, nitrogen, phosphorus, potassium and pH of the soils were measured. Results showed that litter and roots from andropogoneae improved signifi cantly the stock of organic matter of the soil by more than 40%. Andropogon spp. when used in artifi cial fallow improves soil fertility and permits the shortening of fallow duration in tropical areas.

    Desertification affects about two-thirds of the countries of the world, and one-third of the earth's surface, namely one-fifth of the world population. The seriousness of desertification depends on various factors, including climate (temperature, precipitation, wind, humidity), geomorphological and geological condition, vegetation cover, water and wind erosion, soil nutrient status and salinization, land use and land management, biodiversity, etc. Even the climate changes can contribute to the advance of desertification. Indeed hotter and drier conditions would extend the area prone to desertification to encompass areas currently not at risk. In addition, the rate of desertification would increase due to increases in erosion leading to an irreversible status of desertification process. This study was carried out within the FP7-ENV-2010 CLUVA project (CLimate change and Urban Vulnerability in Africa), and aimed to estimate the effects of climate change on sensitivity to desertification in the area of Ouagadougou (Burkina Faso) providing a prediction tool useful for optimization of land management. The approach was based on the implementation and adaptation to the local conditions of the Environmentally Sensitive Areas Index (ESAI), developed within the MEDALUS project (Mediterranean Desertification and Land Use). A noteworthy advantage of this methodology is the flexibility, that allows to take into account several indices (climate, soil, vegetation cover, land management) operationally defined through the inclusion or exclusion of parameters scored on the basis of their impact on sensitivity to desertification. Therefore, an upgrade of the original method was developed adding a further index (Erosion Quality Index) for the evaluation of the cumulative impact of water and wind erosion in desertification process, by the RUSLE equation and the WEQ method, respectively. Climate simulations over the time period 2010-2050 were provided by the CMCC (Centro Euro

    The United Nations Convention to Combat Desertification (UNCCD) defines desertification as "land degradation in arid, semi-arid and dry sub-humid areas resulting from various factors, including climatic variations and human activities". Desertification is regarded as one of the major global environmental problems of the 21st century and the African sub-Sahara is often quoted as the most seriously affected region with a significant loss of biological and economic productivity of the land. In this geographic area, desertification processes are usually generated by soil erosion due to climate characteristics and fluctuations, unsustainable land uses, overgrazing and inappropriate agricultural practices. Preventing desertification requires an improved understanding of its causes, impact, degree and association with climate, soil, water, land cover, socio-economic factors and their combined effects. The development of methodologies capable of managing large amounts of data in an integrated approach is needed because of the complexity and variety of forms of desertification processes. The study was carried out within the FP7-ENV-2010 CLUVA project (CLimate change and Urban Vulnerability in Africa), aimed to estimate the sensitivity to land degradation in the urban and peri-urban areas of both Ouagadougou (Burkina Faso) and Saint Louis (Senegal) cities. The approach was based on the implementation and adaptation of the modeling methodology developed within the MEDALUS project (MEditerranean Desertification and Land Use). The model is characterized by a multi-factor approach based on the assessment of both environmental quality indicators (climate, soil, vegetation) and anthropogenic factors (land management). The methodology is adaptable to the local conditions, considering that some key indicators can be operationally defined through the inclusion or exclusion of parameters and the scores assigned in order to match the specific relevance of the factors.

    Climate changes talks regularly underline that developing countries' agriculture could play a stronger role in GHGs mitigation strategies and benefit from the Kyoto Protocol program of subsidies. Scientists explain that agriculture can contribute to carbon mitigation by storing more carbon in the soil through greener cropping systems. In this context, a growing number of research projects have started to investigate how developing countries agriculture can contribute to these objectives. The clean development mechanism (CDM) proposed in the Kyoto protocol is one particular policy instrument that can incite farmers to mitigate the GHG balance towards more sequestration and less emission. Some economists such as Michael Porter think that environmental regulation lead to a win-win outcome, in which case subsidies are not necessary. If it is a trade-off between incomes and the environment, subsidies are required. CDM can be mobilized to support the mitigation strategy. Agriculture implies the use of inputs. Reducing the emission implies the reduction of those inputs which will in turn imply a yield decrease. The study aims to assess whether this measure will imply a trade-off between environmental and economic objectives or a win-win situation. I apply this study to the case of small farmers in Burkina Faso through environmental instruments such as the emissions limits and agroforestry using a bioeconomic model, in which the farmers maximize their utility subject to constraints. The study finds that the limitation of emissions in annual crops production involves a trade-off. by impacting negatively their net cash come. By integrating perennial crops in the farming system, the farmers' utility increases. Around 6,118 kg are sequestrated individually. By computing the value on this carbon balance, farmers' net cash incomes go better. Then practicing agroforestry is a win-win situation, as they reach a higher level of income, and reduce emissions.

    Introduction L’étude avait pour but de déterminer la fréquence d'isolement des mycobactéries atypiques chez les patients déclarés tuberculeux pulmonaire à microscopie positive (TPM+) au Burkina Faso. Méthodes Il s'est agit d'une étude transversale qui s'est déroulée de mars 2011 à février 2012. Les patients TPM+ de plus de 15 ans ont été inclus dans l’étude de manière systématique dans les centres de diagnostic et de traitement (CDT) de la région sanitaire des Hauts Bassins. Une culture des mycobactéries et une identification biochimique ont été réalisées sur les échantillons des patients TPM+ La sérologie VIH a été réalisée par des tests rapides. Résultats Une fréquence de 11% (8/73) de mycobactéries atypiques et 89,0% (65/73) de mycobactéries du complexe tuberculosis ont été identifiées des 73 patients TPM+ inclus dans l’étude. La tranche d’âge de 20 à 40 ans était la plus touchée par les mycobactérioses en général et constituait 48% de l’échantillon. Nous avons trouvé 12,2% (8 / 66) de patients VIH positif, 83,3% (55 / 66) de patients VIH négatif et 4,5% (3 / 66) de patients dont le statut VIH était indéterminé. Conclusion Notre étude a mis en lumière l'implication des mycobactéries atypiques dans la pathogénie de certains patients déclarés TPM+. Le rôle des mycobactéries atypiques dans les infections pulmonaires est probablement sous estimé et devra être examiné avec plus de détails et sur un échantillon plus grand. PMID:25396014

    Full Text Available Abstract Background In sub-Saharan Africa, the availability and accessibility of oral health services are seriously constrained and the provision of essential oral care is limited. Reports from the region show a very low utilization of oral health care services, and visits to dental-care facilities are mostly undertaken for symptomatic reasons. The objectives of the present study were to describe the prevalence of oral symptoms among adults in Ouagadougou, capital city of Burkina Faso and the use of oral health services and self-medication in response to these symptoms and to measure the associations between predisposing, enabling and needs factors and decisions to seek oral health care. Methods The conceptual design of the study was derived from both the Andersen-Newman model of health care utilization and the conceptual framework of the WHO International Collaborative Study of Oral Health Outcomes. Data were obtained by two-stage stratified sampling through four areas representative of different stages of urbanization of Ouagadougou. The final study population comprised 3030 adults aged 15 years or over and the response rate was 65%. Results Overall, 28% of the respondents had experienced an oral health problem during the past 12 months; a high proportion (62% reported pain or acute discomfort affecting daily life. In response to symptoms, only 28% used oral health facilities, 48% used self-medication and 24% sought no treatment at all. Multivariate analyses revealed that several socio-economic and socio-cultural factors such as religious affiliation, material living conditions and participation in a social network were significantly associated with the use of oral health care services by adults who had experienced oral health problems during the previous year. Conclusion The proportion of people who have obtained oral health care is alarmingly low in Ouagadougou and self-medication appears to be an important alternative source of care for

    Full Text Available Abstract Background Safe, effective and affordable drug combinations against falciparum malaria are urgently needed for the poor populations in malaria endemic countries. Methylene blue (MB combined with chloroquine (CQ has been considered as one promising new regimen. Objectives The primary objective of this study was to evaluate the safety of CQ-MB in African children with uncomplicated falciparum malaria. Secondary objectives were to assess the efficacy and the acceptance of CQ-MB in a rural population of West Africa. Methods In this hospital-based randomized controlled trial, 226 children (6–59 months with uncomplicated falciparum malaria were treated in Burkina Faso. The children were 4:1 randomized to CQ-MB (n = 181; 25 mg/kg CQ and 12 mg/kg MB over three days or CQ (n = 45; 25 mg/kg over three days respectively. The primary outcome was the incidence of severe haemolysis or other serious adverse events (SAEs. Efficacy outcomes were defined according to the WHO 2003 classification system. Patients were hospitalized for four days and followed up until day 14. Results No differences in the incidence of SAEs and other adverse events were observed between children treated with CQ-MB (including 24 cases of G6PD deficiency compared to children treated with CQ. There was no case of severe haemolysis and also no significant difference in mean haemoglobin between study groups. Treatment failure rates were 53.7% (95% CI [37.4%; 69.3%] in the CQ group compared to 44.0% (95% CI [36.3%; 51.9%] in the CQ-MB group. Conclusion MB is safe for the treatment of uncomplicated falciparum malaria, even in G6PD deficient African children. However, the efficacy of the CQ-MB combination has not been sufficient at the MB dose used in this study. Future studies need to assess the efficacy of MB at higher doses and in combination with appropriate partner drugs.

    Background Intermittent screening and treatment (IST) of malaria during pregnancy has been proposed as an alternative to intermittent preventive treatment in pregnancy (IPTp), where IPTp is failing due to drug resistance. However, the antenatal parasitaemias are frequently very low, and the most appropriate screening test for IST has not been defined. Methodology/Principal Findings We conducted a multi-center prospective study of 990 HIV-uninfected women attending ANC in two different malaria transmission settings at Tororo District Hospital, eastern Uganda and Colsama Health Center in western Burkina Faso. Women were enrolled in the study in the second or third trimester of pregnancy and followed to delivery, generating 2,597 blood samples for analysis. Screening tests included rapid diagnostic tests (RDTs) targeting histidine-rich protein 2 (HRP2) and parasite lactate dehydrogenase (pLDH) and microscopy, compared to nPCR as a reference standard. At enrolment, the proportion of pregnant women who were positive for P. falciparum by HRP2/pan pLDH RDT, Pf pLDH/pan pLDH RDT, microscopy and PCR was 38%, 29%, 36% and 44% in Uganda and 21%, 16%, 15% and 35% in Burkina Faso, respectively. All test positivity rates declined during follow-up. In comparison to PCR, the sensitivity of the HRP2/pan pLDH RDT, Pf pLDH/pan pLDH RDT and microscopy was 75.7%, 60.1% and 69.7% in Uganda, 55.8%, 42.6% and 55.8% in Burkina Faso respectively for all antenatal visits. Specificity was greater than 96% for all three tests. Comparison of accuracy using generalized estimating equation revealed that the HRP2- detecting RDT was the most accurate test in both settings. Conclusions/Significance The study suggests that HRP2-based RDTs are the most appropriate point-of-care test currently available for use during pregnancy especially for symptomatic women, but will still miss some PCR-positive women. The clinical significance of these very low density infections needs to be better defined. PMID

    Full Text Available Dépendance économique aux produits forestiers non ligneux : cas des ménages riverains des forêts de Boulon et de Koflandé au Sud-Ouest du Burkina Faso Résumé Cette étude a pour objectif d’évaluer la dépendance économique des ménages riverains des forêts de Boulon et de Koflandé aux produits forestiers non ligneux (PFNL et d’identifier les déterminants de cette dépendance. Des enquêtes ont été menées auprès de 583 ménages de 14 villages riverains de ces forêts. Les résultats montrent que le revenu moyen annuel par ménage est de 846 800 F CFA avec une contribution de 60% du revenu des cultures et 12% du revenu d’élevage. Les PFNL procurent en moyenne 72 479 F CFA par ménage et par an à près de 93% des ménages enquêtés. La dépendance économique des ménages aux PFNL est estimée à 12%. Elle diminue avec le revenu, traduisant une plus grande dépendance des ménages pauvres des PFNL. Par ailleurs, les hommes sont économiquement moins dépendants des PFNL que les femmes. Les principaux déterminants de la dépendance aux PFNL sont le statut d’autochtone, la taille du ménage, la superficie forestière et la densité de population du département qui affectent positivement la dépendance aux PFNL. Dans le cadre d’une politique de réduction de la pauvreté en milieu rural, il faut prendre des mesures qui favorisent l’accès durable des ménages les plus pauvres aux ressources forestières.

  2. How do cowpea and groundnut improve soil N fertility and yields of succeeding sorghum crop in the Guinean savannah zone of Burkina Faso (West Africa)?

    International Nuclear Information System (INIS)

    Field experiments were carried out in a weakly acid (pH H2O 6.5) Ultisol at Farako-Ba (4 deg 20' West, 11 deg 6' North and 405 m altitude) in the Guinean savannah zone of Burkina Faso to study the beneficial effects of cowpea (Vigna unguiculata) and groundnut (Arachis hypogaea) on grain yield of succeeding sorghum. The first experiment was a factorial of three crop rotations (cowpea-sorghum, groundnut-sorghum and sorghum-sorghum) as first factor and five fertilizer treatments (NPK fertilizer, NPK+ dolomite, NPK+ manure, NK+ phosphate rock and a control) as second factor in a split plot design with a randomised block arrangement and four replications. Soil mineral N, nematode infection and fertilizer N recoveries were studied during three years (2000 to 2002). Biological nitrogen fixation (BNF) in cowpea and groundnut was measured in the second year (2001) with 15N isotopic dilution method using a non-fixing cowpea as reference crop. Groundnut fixed 8 to 23 kg N ha-1 and the percent of N derived from the atmosphere (% Ndfa) varied from 27 to 34%. Cowpea fixed 50 to 115 kg N ha-1 and the Ndfa varied from 52 to 56%. Compared to mineral NPK fertilizer alone, legumes fixed more nitrogen from the atmosphere when NPK fertilizer was combined with dolomite or manure. Compared to water-soluble phosphate, phosphate rock increased BNF by cowpea. Highest responses to N fertilizer applications were found when sorghum was rotated with legumes and the lowest in mono cropping of cereals. Compared to mono cropping of cereals (maize-sorghum or sorghum-sorghum), sorghum produced 2.9 and 3.1 times more grain yields when it was rotated with groundnut or cowpea respectively. In a second experiment, the response of a succeeding sorghum to N fertilizer, nitrogen fertilizer equivalencies (NFE) of the two legumes and nematode infection in the soil and roots of the succeeding sorghum were studied. The NFE of groundnut (35 kg N ha-1) was higher than that of cowpea (25 kg N ha-1). However, soil

    Desertification is regarded as one of the major global environmental problems of the 21st century. The African sub-Sahara is often quoted as the most seriously affected region with a significant loss of biological and economic productivity of the land due to climate characteristics and fluctuations, unsustainable land uses, overgrazing and inappropriate agricultural practices. Due to its complexity, dynamism and extent, desertification is complicated to check and assess. The absence of an agreed methodology for the identification of affected areas is a critical point in desertification monitoring and assessment. An integrated approach which uses both qualitative and quantitative measures is crucial to reach the aim of sustainable resource use and has to be reflected in application of sets of indicators. The selection of appropriate indicators and their integration and interpretation should be conducted by the objectives to be achieved and the questions to be answered. This study, carried out within the FP7-ENV-2010 CLUVA project (Climate change and Urban Vulnerability in Africa), aimed to assess the sensitivity to desertification in peri-urban areas of both Ouagadougou (Burkina Faso) and Saint Louis (Senegal) cities. The approach was based on the implementation and adaptation to the local conditions of the modeling methodology developed within the MEDALUS project (Mediterranean Desertification And Land Use). The model is characterized by a multi-factor approach based on the assessment of both environmental quality indicators (vegetation, soil, climate) and anthropogenic factors (land management). All local data, arranged in a GIS environment, allowed the generation of maps identifying Environmentally Sensitive Areas (ESAs) and an Index of Environmentally Sensitive Areas (ESAI). Changes and integrations to the original methodology have been set taking into account the environmental and social features of the whole sub-Saharan west Africa in order to allow the use of

    Full Text Available Glossina palpalis gambiensis et G. tachinoides sont des vecteurs majeurs des trypanosomoses humaines et animales en Afrique de l’Ouest. Sur une partie de leur aire de répartition, elles sont présentes en sympatrie, mais très peu d’informations sont disponibles sur leurs interactions. Nous avons capturé ces deux espèces en utilisant un système attractif composé d’écrans de tissu noir/bleu/ noir muni de film adhésif, afin de retenir toutes les glossines posées et de pouvoir mesurer la hauteur à laquelle elles se sont posées, ainsi que leur rythme d’activité en fonction de l’heure de la journée. L’étude a eu lieu dans deux zones du sud du Burkina Faso : Kartasso en amont du fleuve Mouhoun, où seule G. p. gambiensis est présente, et Folonzo sur le fleuve Comoé, où les deux espèces cohabitent. Les résultats, sur 3 800 glossines capturées, montrent une forte prédominance des captures de G. tachinoides par rapport à G. p. gambiensis à Folonzo (84 % contre 16 % des captures respectivement. À Kartasso, où elle est seule, G. p. gambiensis est capturée en moyenne à 46 cm du sol. À Folonzo, G. p. gambiensis est en moyenne attrapée à une hauteur de 65 cm, et G. tachinoides à 55 cm, ces différences de hauteurs étant significatives. Les femelles sont capturées en général plus haut que les mâles. Les deux espèces montrent un rythme d’activité similaire en fonction de l’heure de capture, mais seule G. p. gambiensis réduit sa hauteur de vol aux heures les plus chaudes. Plusieurs hypothèses, non exclusives, sont évoquées pour expliquer ces hauteurs de capture différentes : la nature de la galerie forestière, un comportement d’approche qui différerait entre espèces, mais aussi la possibilité de phénomènes de compétition interspécifique en relation avec l’utilisation de ressources énergétiques limitées (métabolisme lié à la proline.

    Full Text Available Abstract Background Intermittent preventive treatment with sulphadoxine-pyrimethamine for pregnant women (IPTp-SP is currently being scaled up in many countries in sub-Saharan Africa. Despite high antenatal clinic (ANC attendance, coverage with the required two doses of SP remains low. The study investigated whether a targeted community-based promotion campaign to increase ANC attendance and SP uptake could effectively improve pregnancy outcomes in the community. Methods Between 2004 and 2006 twelve health centres in Boromo Health District, Burkina Faso were involved in this study. Four were strategically assigned to community promotion in addition to IPTp-SP (Intervention A and eight were randomly allocated to either IPTp-SP (Intervention B or weekly chloroquine (Control. Primi- and secundigravidae were enrolled at village level and thick films and packed cell volume (PCV taken at 32 weeks gestation and at delivery. Placental smears were prepared and newborns weighed. Primary outcomes were peripheral parasitaemia during pregnancy and at delivery, placental malaria, maternal anaemia, mean and low birth weight. Secondary outcomes were the proportion of women with ≥ 3 ANC visits and ≥ 2 doses of SP. Intervention groups were compared using logistic and linear regression with linearized variance estimations to correct for the cluster-randomized design.

    The impact of a Computerized Immunization Register (CIR) on Expanded Program on Immunization (EPI), with sending SMS to parents before immunization sessions, has never been studied in sub-Saharan Africa. The objective of this study is to measure EPI quickness and completeness of vaccinations after sending call-back SMS to parents through CIR put in place in a health center. In a health center, chosen at random (Colma 1) in the city of Bobo Dioulasso, Burkina Faso, West Africa, mothers, at first EPI session, if they had a mobile phone available at hand or in her surrounding, were randomized for receiving, or not, a call-back SMS before following EPI sessions, after child registration on a Francophone CIR (Siloxane's Intervax ©). Mothers, which were sent SMS and did not correctly followed sessions were asked through mobile phone why their child was late for EPI. 523 newborns were included in the study, with 253 whose parents were sent SMS, and 268 being informed of sessions only by ordinary methods. At second EPI session at 2 months of age, there was a statistical significant increase of coverage for children whose parents received SMS (pSMS (p=0.03). At third EPI session at 3 months of age, attendance to EPI for children whose parents were sent SMS was significantly better (pSMS (p=0.02). At fourth EPI session at 4 months of age, attendance for children with SMS was significantly better for children whose parents were sent SMS (pSMS, 19 (19%) parents could not be reached on the telephone. 31/82 (38%) mothers had shifted for EPI to a more proximate vaccination center (Colma 2), and 5 (6%) to private or civil servants clinic. 14/82 (17%) mothers had been travelling far from health center. Ten (12%) admitted neglect of EPI sessions. Two (2%) children had deceased, and one mother did not come back to Colma 1 after her child's AEFI. One child has been dismissed two times of vaccination following recommendation not to open a measles multi-dose vial for a single child

  9. Unintentional topical lindane ingestions--United States, 1998-2003.

    Science.gov (United States)

    2005-06-01

    Lindane is an organochlorine pesticide found in certain prescription-only shampoos and topical lotions used to treat pediculosis (i.e., lice infestation) and scabies; lindane has been associated with human neurologic toxicity. In 2004, CDC was alerted to cases of illness caused by unintentional ingestion of lindane by persons mistaking the product for a liquid oral medication (e.g., cough syrup). To assess the extent of illness from ingestion of lindane, CDC, with assistance from the U.S. Environmental Protection Agency, Food and Drug Administration (FDA), and state health departments, collected case reports and analyzed data from the Sentinel Event Notification System for Occupational Risks-Pesticides (SENSOR-Pesticides) program and the Toxic Exposure Surveillance System (TESS). This report summarizes the results of that analysis, which identified 870 cases of unintentional lindane ingestion during 1998-2003, and describes two examples of lindane ingestions. To reduce the risk of lindane ingestion, public health authorities should alert clinicians to the hazards of lindane and the importance of following FDA usage guidelines, which include dispensing lindane in manufacturer-produced, 1- or 2-ounce single-use containers.

    Full Text Available Technical and Economic Performance of Maize/Cowpea and Maize/Mucuna Associations in the Real Situation of Cultivation in Burkina Faso: Potentials and Constraints. Western Burkina Faso, population pressure has led to the abandonment of fallow. Continuous cropping of cotton and maize are recognized to severely reduce soil fertility. In order to increase the productivity of cropping systems and contribute to the recovery of soil fertility, farmers of Tuy involved in the "Fertipartenaires" project decided to test different maize and legume intercropping patterns. The objective of the study was to develop experimentation in farmers' conditions concerning maize/legume intercrops which should be economically efficient and technically acceptable. Volunteer producers have tested the maize/cowpea (13 producers and the maize/mucuna (10 producers. Cowpea was already produced by farmers as a cash or food-crop at a small-scale in pure stands for grain products and mucuna was newly introduced as a fodder crop for cattle.The maize-legume intercropping was a new practice in the region. For each experimental plot, the intercropping was compared with the sole cultivation of corn (control. The sets of production practices (SPP were monitored until the measure of the yield. For both intercrops, homogeneous SPP were defined by principal component analysis (PCA and hierarchical ascending classification (HAC and the most efficient ones, technically and economically, were compared with monoculture of maize by variance analysis (ANOVA. It emerged that the dates of tillage and sowing, plant density, date of weeding, and soil fertility levels are the performance factors for maize/ legume intercrops. Maize/legume intercropping lead significantly (P< 10% to an increase of biomass from 22 to 29% compared to monoculture of maize without increasing the work duration. The maize/cowpea intercrop provided higher income than the maize/ mucuna one. Studies should continue to improve

    rendement de lait implique nécessairement une référence à sa productrice : la vache. Ici déjà, la question de genre est introduite. L’entretien du troupeau est la fonction de l’homme, tandis que l’exploitation du lait revient à la femme. Or cette fonction d’exploitation du lait assoit dans le même temps une liberté économique de la femme qui en est la propriétaire. Enfin cet article montre le pouvoir symbolique et social donné à la femme, affirmé par le lait maternel. Celui-ci est le vecteur des plus grandes qualités nécessaires à un « bon peul », mais peut aussi devenir la voie de transmission de pouvoirs maléfiques. Maîtresse du pouvoir lacté, la femme en hérite d’un statut particulier propre à la société peule.When milk becomes a social issue: the FulBe case in Burkina FasoThe question of breastfeeding as a factor of HIV transmission is a reason for interest in milk as a subject of research. Mother-child transmission of HIV is an important public health issue in the South. The successful implementation of preventive programmes requires different approaches, such as those of the social sciences. The perceptions which valorize breastfeeding are deeply rooted in the majority of ‘traditional’ societies, and these perceptions valorize in turn local perceptions of milk. In effect, in FulBe society, milk has a value which goes beyond the simple question of breastfeeding, being present at the very heart of the socio-economic structure. It is this aspect which constitutes the focus of this article.The FulBe’s word of milk also means ‘that which is the best’. Milk and its producers, cows, are the fundament of local socio-economic organization. Men are in charge of the care of the herd while women are concerned with the exploitation of milk. In this particular ethnographic case, milk provides women with the possibility of economic and social emancipation, because milk becomes the property of women as soon as they are married and they

    Full Text Available Crops Residues Management Effects on Crops Yields and Mineral Balance in a Cotton- Maize- Sorghum Rotation in Burkina Faso. The effect of crop residues management on crops yields and nutrients balances in a cotton-cereals cropping system was studied in a long-term experiment carried out from 1982 to 2006. The experimental design was a simple nonrandomized blocks comparing extensive management of crops residues (T1, semiintensive management of crops residues (T2 and intensive management of crops residues (T3. Crops yields, soil chemical properties and mineral balances were measured. Results showed that after 25 years, soil carbon contents decrease was respectively 44%, 15% and 13%, with an extensive, semi-intensive and intensive management of crops residues. Total phosphorus decrease was 25% in all the treatments. Exchangeable Ca and Mg declined from 2.43 to 1.37 cmol+ kg-1 and 0.9 to 0.29 cmol+ kg-1 respectively while the Sum of Exchangeable Bases declined from 3.79 to 1.79 cmol+ kg-1. Recycling crops residues to compost and manure increased cotton yields from 13 to 22 %, maize yields from 45 to 60 %, and sorghum yields from 19 to 44%. Mineral balance in N, P, K and S was improved after 25 years of continuous cultivation while using compost or manure. At the same time, the decline of soil properties was due to nutrients losses which need to be evaluated. This study recommends integrated crops residues management and the use of rock phosphate to improve sustainability in cottoncereals cropping systems.

    People screened for human immunodeficiency virus (HIV) using rapid diagnostic tests (RDTs) in Africa remain generally unaware of their status for hepatitis B (HBV) and hepatitis C (HCV) infections. We evaluated a two-step screening strategy in Burkina Faso, using both HIV RDTs and Dried Blood Spot (DBS) assays to confirm an HIV-positive test, and to test for HBV and HCV infections. HIV counselling and point-of-care testing were performed at a voluntary counselling and testing centre with HBV, HCV status and HIV confirmation using DBS specimens, being assessed at a central laboratory. Serological testing on plasma was used as the reference standard assay to control for the performance of DBS assays. Nineteen out of 218 participants included in the study were positive for HIV using RDTs. A fourth-generation HIV ELISA and immunoblot assays on DBS confirmed HIV status. Twenty-four out of 25 participants infected with HBV were found positive for hepatitis B surface antigen (HBsAg) using DBS. One sample with a low HBsAg concentration on plasma was not detected on DBS. Five participants tested positive for HCV antibodies were confirmed positive with an immunoblot assay using DBS specimens. Laboratory results were communicated within 7 days to participants with no loss to follow up of participants between the first and second post-test counselling sessions. In conclusion, DBS collection during HIV point-of-care testing enables screening and confirmation of HBV, HCV and HIV infections. Diagnosis using DBS may assist with implementation of national programmes for HBV, HCV and HIV screening and clinical care in middle- to low-income countries. PMID:23902574

    Specimens described as Rhadinorhynchus niloticus Meyer, 1932 (Rhadinorhynchidae) from two male specimens collected from Heterotis niloticus (Cuvier) in the Egyptian Nile were later redescribed in the genus Tenuisentis Van Cleave, 1936 (Tenuisentidae) based on 12 specimens collected from the same host species in the White Nile. That redescription basically distinguished the two genera based on five traits but did not actually provide a formal description. His account left out information about cerebral ganglion, lemnisci, some reproductive structures, eggs, proboscis hook dissymmetry and roots, size of trunk and a few other structures. We provide (i) the first complete description of this species enhanced by SEM, molecular, and histo-pathological studies; (ii) expand the existing descriptions; (iii) correct questionable accounts advanced by Van Cleave on the cement gland and the hypodermal giant nuclei; and (iv) add descriptions of new features such as the para-receptacle structure which we also report from Paratenuisentis Bullock & Samuel, 1975, the only other genus in Tenuisentidae Van Cleave, 1936. The subsequent description of a few more specimens from the same host collected in Mali was more informative yet incomplete and at variance with our specimens from Burkina Faso. Genetic divergence and phylogenetic analyses of mitochondrial (cytochrome oxidase c subunit I; COI) and nuclear (18S ribosomal RNA) gene relationships uncovered a cryptic species complex containing two lineages. Based on our studies, the family diagnosis is emended. The acanthocephalan causes damage to the host intestine as depicted in histopathological sections. The invading worm can extend from the mucosal layer to the muscularis externa of the host with subsequent tissue necrosis, villi compression, haemorrhaging and blood loss. PMID:26790681

  16. IgG1 and IgG4 antibody responses to the Anopheles gambiae salivary protein gSG6 in the sympatric ethnic groups Mossi and Fulani in a malaria hyperhendemic area of Burkina Faso.

    Cinzia Rizzo

    Full Text Available Human antibody response to the Anopheles gambiae salivary protein gSG6 has recently emerged as a potentially useful tool for malaria epidemiological studies and for the evaluation of vector control interventions. However, the current understanding of the host immune response to mosquito salivary proteins and of the possible crosstalk with early response to Plasmodium parasites is still very limited. We report here the analysis of IgG1 and IgG4 subclasses among anti-gSG6 IgG responders belonging to Mossi and Fulani from Burkina Faso, two ethnic groups which are known for their differential humoral response to parasite antigens and for their different susceptibility to malaria. The IgG1 antibody response against the gSG6 protein was comparable in the two groups. On the contrary, IgG4 titers were significantly higher in the Fulani where, in addition, anti-gSG6 IgG4 antibodies appeared in younger children and the ratio IgG4/IgG1 stayed relatively stable throughout adulthood. Both gSG6-specific IgG1 and IgG4 antibodies showed a tendency to decrease with age whereas, as expected, the IgG response to the Plasmodium circumsporozoite protein (CSP exhibited an opposite trend in the same individuals. These observations are in line with the idea that the An. gambiae gSG6 salivary protein induces immune tolerance, especially after intense and prolonged exposure as is the case for the area under study, suggesting that gSG6 may trigger in exposed individuals a Th2-oriented immune response.

    Full Text Available Farmers' Practices and Strategies for Ruminants' Supplementation in Mixed Crop-livestock Farming Systems in the Central Plateau and North of Burkina Faso. With the purpose to understand the farmers' practices and strategies for ruminants supplementation, mixed crop-livestock farms have been surveyed in three agro-ecological zones of Burkina Faso. The results obtained indicated that lactating females' supplementation is almost permanent whatever be the period of the year, but the objectives vary according to the seasons. In general, animal supplementation during the dry season deals with four major objectives: (i incomes generation, (ii care of draught animal, (iii productivity, and (iv risks management for animal losses (thefts and mortalities. When the nutritional stress becomes important, incomes generation gives up progressively the ground to the risk management. The supplementation strategy relies on a maximum valorization (70-80% of the cases of feeds produced in the farm or collected in the bush. Farmers also purchase feeds (salt, cereals bran, agro-industrial by-products in cash and, livestock remains the frequent source of funds. The results of the study suggest that the development of feeding systems for these mixed crop-livestock farms would focus on alternatives considering the variability of farmers' objectives by the time, and being built on feed that can be easily mobilized by farmers, and offering a low cash cost price, for example green forage and fruit of shrubs rich in energy and nitrogen.

    Objectifs l’augmentation du taux de personnes qui connaissent leur statut VIH est un impératif, notamment en Afrique subsaharienne, ce qui impose d’évaluer les stratégies utilisées pour accroître la fréquentation des services de dépistage. Cet article vise à faire le bilan de la pertinence, de la faisabilité et de l’efficacité des campagnes nationales de dépistagemenées entre 2006 et 2010 au Burkina Faso. Méthodologie une analyse de toutes les données de fréquentation du conseil dépistage sur cette période a été faite, couplée à des entretiens avec les principaux acteurs intervenant dans le dépistage. Résultats les résultats montrent que les huit campagnes de dépistage organisées sur la période ont permis à 487 727 personnes de faire leur test VIH. Ce nombre représente 50 % du nombre total de personnes ayant fait leur test et contribue à hauteur de 24,6 % au dépistage des personnes séropositives identifiées au cours de cette période. Les campagnes ont touché des populations difficiles à atteindre (en particulier les jeunes), à un coût moindre. Conclusions cette stratégie est donc pertinente pour identifier les personnes VIH+. Son intérêt pour la prévention, important selon les soignants et au vu des populations jeunes qui y participent, devrait être mesuré par des études complémentaires. Les campagnes sont efficaces et coût-efficaces même dans un pays de niveau de prévalence faible. Ces résultats soulignent l’intérêt de la synergie entre les associations et les services de santé dans l’offre de services de conseil et dépistage. PMID:24681563

This study aimed to establish an overview of the main actors of the sub-urban agriculture of Ouagadougou, their practices and expectations, and to characterize the used organic substrates (OS. For that, a farm survey was carried out on the most representative sites with 64 persons (cereal farmers, truckers and nurserymen randomly chosen. OS were sampled with each actor, when available. Thus, 27 samples were taken and characterized through chemical analyses and laboratory incubations to follow organic carbon mineralization. The results highlighted that 35% of cereal farmers, 69% of truckers and 95% of nurserymen were 20 to 40 years old, that a large proportion of cereal farmers and truckers were not sent to school while 70% of nurserymen had at least primary education. Sub-urban agriculture was the only activity for 43% of farmers, 83% of truckers and 91% of nurserymen. Moreover, 71% of cereal farmers and 73% of nurserymen used municipal wastes as source of organic matter against only 17% of truckers, the majority of them using animal manures. The main criterion of choice of OS was their availability without any other consideration. Even if a large majority of the actors think that composts of OS were better than brut OS, a minority of them used currently composts. The best ways for an adoption and utilization of OS composts were to facilitate their accessibility and to promote these composts, composting techniques and their interests through advertising in mass media. Chemical analyses and laboratory incubations showed a great variability of the SUW, both in the same group and actors' groups. However, in case of total organic carbon, total nitrogen and total phosphorous contents, the following tendencies were observed: Contenttruckers > Contentfarmers > Contentnurserymen. For the

    Full Text Available Contribution to the study by PY/GC-MS of organic matter linked to fine particles (0-50 µm in some soils under long-term natural formations in Burkina Faso. The study aims to enhance the knowledge on organic matter of Arenosols, Ferralsols, and Cambisols in Burkina Faso. It deals with the distribution of C and N in three particles size fractions and is focused on the structures of organic matter linked to the (0-50 µm fraction. The results showed that total organic matter was lower than 2% in all soil units. More than 70% of total carbon were held by the finest fraction. The main products released by PY/GC-MS technique of the (0-50 µm fraction were lignin derived compounds, non lignin derived aromatic compounds, carbohydrates derived compounds, fatty acids methyl esters and nitrogen derived compounds. The aliphatic compounds ranged from C12 to C18, C16 being the dominant one. The aliphatic compounds were negatively correlated with the aromatic compounds. A positive correlation was observed between the nitrogen derived compounds and the amounts of clay. On the other hand, the carbohydrates derived compounds were negatively correlated with clay particles. Furthermore, the study pointed out some different structures of lignin such as syringyl, guaiacyl, and p.hydrophenyl. Depending on the nature of wood (hard wood, soft wood and grasses, they reflected the composition of vegetation on the studied sites. Therefore, PY/GC-MS technique was efficient for structural characterization of low amounts of soil organic matter.

    Full Text Available Legume and Cereal Cropping in Zaï System with Different Organo-mineral Amendments - Productivity and Impact on Biological Properties of Degraded Bare Alfisol in North Sudanian Zone of Burkina Faso. Zaï is an agricultural practice that allows the cultivation of abandoned degraded soils. An experiment was conducted from 2006 to 2012 in Burkina Faso to assess the impact of this practice on the production of sorghum and cowpea, as well as on the biological properties of soils. The experiment was set up according to a factorial experimental design in Fischer blocks. The crops were grown in the trial , received different types of organic (manure, compost and mineral (rock phosphate input. The results showed that the intake of simple manure and compost significantly increased the yield of the two crops. The addition of phosphate (2 t.ha-1 to compost (3 t.ha-1 and to manure (3 t.ha-1 increased the yields of cowpea and sorghum respectively by 70 to 80% and 88 to 160% compared to sole compost and manure applications. The biological activity of the soil was not influenced by the type of crop but rather by organo-mineral intakes. The combination of rock phosphate to manure had a particularly positive effect on soil biological activity. The natural phosphate intake associated with organic matter therefore appears essential to maintain crop production and soil properties.

    The authors describe three cases of trilateral retinoblastoma, a rare syndrome that occurs most often in young children. Two of these children were 3 years old at diagnosis, and the other 4 years old. The retinoblastoma was unilateral in one child and bilateral in the others. All underwent computed tomography (CT) imaging, which made it possible to locate the intraocular tumor lesions, to specify the extent of the tumor and to look for a possible intracranial neoplasm. Unfortunately, the cost of CT is high, which limits its use in our context. PMID:20199945

    International Nuclear Information System (INIS)

    The long-term effects of annual fallow and two grain legumes, namely groundnut (Arachis hypogea) and cowpea (Vigna unguiculata) on soil N, fertilizer N recovery and yield of subsequent non-fixing crops were investigated in two ecological savannah zones of West Africa. The effects of fallow and groundnut on sorghum (Sorghum bicolour) and cotton (Gossypium sp) were studied using a 10-year (1993-2003) field experiment at the agronomic research station of Farako-Ba (4 deg. 20' West, 11 deg. 6' North and 405 m altitude) in Guinean savannah zone Burkina Faso. A factorial 3x8 design in a split plot arrangement was used. Three crop rotations (cotton-groundnut-Sorghum, fallow-sorghum and mono cropping of sorghum) were used as first factor and 8 fertilizer treatments (mineral NPK fertilizer, NPK+crop residues, NPK+dolomite, PK+crop residues, PK+manure, PK+compost, PK and control) were applied as second factor. In the Sudanian savannah zone, a 5-year (1995-1999) field experiment was laid down at the research station of Kouare (11 deg 59' North, 0 deg. 19' West and 850 m altitude). A factorial of three cropping systems (cowpea-sorghum, fallow-sorghum and mono cropping of sorghum) as a first factor and 4 fertilizer treatments (mineral NPK fertilizer, NPK+dolomite, PK+manure and a control) as a second factor in a split plot design was used. In the Guinean savannah zone, grain yields of succeeding sorghum increased from 547 kg ha-1 in continuous sorghum to 912 and 1021 kg ha-1 in fallow-sorghum and cotton-groundnut-sorghum rotations respectively. Soils of fallow-sorghum and cotton-groundnut-sorghum rotations contained more mineral N at sowing. The N fertilizer use efficiency increased from 19% for the continuous sorghum to 32 and 51% for the fallow-sorghum and cotton-groundnut-sorghum respectively. Soil organic carbon increased from 0.36% in continuous sorghum to 0.39 and 0.54% in cotton-groundnut-sorghum and fallow-sorghum rotations respectively. Compared to the original soil

    Full Text Available Physiological answer and productivity of the cultures in a traditional agroforestry system: the case of maize (Zea mays L. associated with the shea tree (Vitellaria paradoxa Gaertn. in the east zone of Burkina Faso. This study was focused on the behaviour of maize cultivated in a forest park of shea butter tree. The surfaces under the influence of shading of the two forms of canopy of this species, termed ball and brush, were compared with the zone located outside the shade of the canopy. Soil water content, growth and productivity of maize were evaluated in these zones. Rainfall was higher under the brush canopy than under the ball canopy. The soil water content appeared to be higher under the ball canopy than the brush canopy in August and September, because of the importance of the shading due to the ball canopy, which contributes to reduce transpiration of the crop and evaporation of water from the soil. Soil water matrix potential variation was higher both under the brush canopy and outside the shade of the canopy. Grain and ear yield as well as stem biomass were relatively higher under the brush canopy than the ball canopy. However they were lower under than outside the canopy.

    The Integrated Microphysics and Chemistry on Trajectories (IMPACT) model is used to study Polar stratospheric cloud formation and evolution in the Southern Polar vortex during the 1998-2003 winters. The model is applied to individual air parcels which are advected through the vortex on UKMO wind and temperature fields. The parcel temperature and pressure histories are used by IMPACT to calculate the formation and sedimentation of ice, NAT, SAT, and STS aerosols. Model results are validated by the Polar Ozone and Aerosol Measurement (POAM) III solar occultation instrument. Comparisons of POAM data to the model results help to constrain the microphysical parameters influencing aerosol formation and growth. Measurements of the water vapor mixing ratio are of limited use in clarifying the model microphysics; however, POAM measurements of aerosol extinction prove to be valuable in differentiating model runs. Specifically, the relationship of aerosol extinction to temperature arises from the different temperatures at which the various particle types form and grow. Comparisons of IMPACT calculations of this relationship to POAM measurements constrain the initial fraction of nuclei available for heterogeneous NAT freezing to 0.02% of all aerosols. Constraints are also placed on the ice accommodation coefficient and the NAT-ice lattice compatibility factor. However, these two parameters have similar effects on the extinction-temperature relationship, and thus a range of values are permissible for each.

    Full Text Available Effects of the Association of Compost and Mineral Fertilizer on the Productivity of Cotton and Maize Cropping System in Burkina Faso. To improve the productivity of a cotton - maize rotation using organic and mineral fertilization, a study was carried out in experimental station from 2008 to 2010. Five levels of compost (0, 2, 6, 9 and 12 t of dry matter ha­1 combined to four rate of mineral fertilizer were compared in split­plot statistical design. The physical and chemical characteristics of soil, crop yields, as well as the mineral nutrition of maize and cotton plants were evaluated. The results show that the content of assimilable P and available K was significantly improved in amended soils by compost which had no significant effect on the carbon content. In amended soils, compost improved plants nutrition which was correct in nitrogen and potassium for cotton and deficient in nitrogen and phosphorus for maize. Compared to control soil, compost combined to mineral fertilizers increased significantly yields with a better efficacy for the recommended mineral manure. The application of 2 t ha­1 of compost per year was as effective as high doses of compost in the second year, and more effective than the latter in the third year. An economy on the recommended dose of mineral fertilizer could be considered, with an annual input of 2 t ha­1 of compost to the mineral fertilizers necessary to maintain the productivity of the cotton­cereal cropping systems.

Méthodes Nous avons menée une étude à visée descriptive et analytique comportant un volet ré-trospectif du 01 janvier 2006 au 31 décembre 2010 portant sur les paramètres épidémiologiques, cliniques des nouveau-nés hospitalisés et un volet prospectif du 3 octobre 2011 au 29 février 2012 par une entrevue des accompagnateurs des nouveau-nés et des prestataires des services de santé. Résultats Les hospitalisations ont augmenté de 43,65% entre 2006 à 2010 Le taux de mortalité néo-natale hospitalière qui était de 11,04% a connu une réduction moyenne annuelle de 3,95%. L'entrevue a porté sur 110 accompagnateurs et 76 prestataires. La majorité des prestataires (97,44%) et des ac-compagnateurs (88,18%) étaient informés de la stratégie mais n'avait pas une connaissance exacte de sa définition. Les prestataires (94,74%) ont signalé des ruptures de médicaments, consommables médicaux et des pannes d’ appareils de laboratoire et d'imagerie. Parmi les accompagnateurs (89%) disaient être satisfaits des services offerts et (72,89%) trouvaient les coûts abordables mais évoquaient les difficultés du transport. Conclusion: La subvention a amélioré la prise en charge du nou-veau-né mais son optimisation nécessiterait une meilleur information et implication de tous les acteurs.

    We used seasonal ground total counts and remote sensing and GIS technology to relate elephant (Loxodonta africana africana) distribution at Nazinga Game Ranch to environmental and anthropogenic factors. Variables used in analyses were normalized difference vegetation index, elevation, stream density, density of poaching and human illegal activities, distance to dams, distance to rivers, distance to roads, and distance to poaching risk. Contrary to our expectation, road traffic did not disturb elephants. Strong negative relationships were documented between elephant abundance and stream density, distance to dams, and poaching density. Density of poaching and other human illegal activities explained 81%, vegetation greenness 6%, and stream density 3% of the variation in elephant density. Elephant distribution represented a survival strategy affected by poaching, food quality and abundance, and water availability.

    To describe the semiological and immunological features of connective tissue diseases seen at the Yalgado Ouédraogo University Hospital in Ouagadougou. A retrospective study reviewed the records of patients seen in the hospital dermatology and internal medicine departments from January 1, 2004, through December 31, 2009 and diagnosed with systemic lupus erythematosus (SLE), systemic sclerosis (ScS), dermatopolymyositis (DPM), primary Gougerot-Sjögren disease (GS), polymyositis (PM) or indeterminate connective tissue disease (ICTD) meeting the criteria of the American College of Rheumatology. The study included 42 patients, 36 women and 6 men. Their mean age was 41.2 years ±11.97 (range: 15-75). SLE was the diagnosis for 10 patients, ScS for 14, DPM for 7, primary GS for 1, PM for 1, and ICTD for 9. Hematologic (93%), cutaneous (88%), and rheumatologic (81%) abnormalities were the most frequent manifestations. The specific auto-antibodies associated with SLE patients were: anti-native DNA (3/6), anti-Sm (3/6), anti-RNP (3/6), and anti-SSA (4/6); anti-Scl 70 antibodies were present in 5 patients with ScS. Connective tissue diseases seem to be rare in Africa, south of the Sahara. However, the very fragmentary studies and the weak healthcare coverage do not allow any definitive conclusions.

    The specificity of the Antigen ELISA was determined by examining 320 bovine serum samples from a tsetse free area and found to be high for the three trypanosome species pathogenic to cattle. By using parasitological techniques in conjunction with the Ag-ELISA it was possible to greatly increase the number of animals found positive for trypanosomes in a tsetse endemic area. For example T. brucei was detected in a region where it had not been encountered previously. The Ag-ELISA will be used to monitor the efficacy of past on-going tsetse control programs.

    La evolución de la capitalización bursátil de las operadoras de telecomunicaciones durante el periodo 1998-2003 puede dividirse en tres etapas: Expansión; Reparación y Nuevo Equilibrio.
    La primera etapa de expansión se caracteriza por un fuerte crecimiento orgánico e inorgánico de las compañías, donde generalmente este último crecimiento, dado principalmente por adquisiciones y fusiones, es financiado mediante aportaciones de capital de sus accionistas o emisiones de deuda. Este crecimiento alimenta a todo el sistema, incrementando de manera continuada su valor. Durante el año 2000 se produce el primer punto de inflexión profundo en esta tendencia alcista del valor de los activos debido a una ineficiencia del sistema económico donde se produce una transferencia desequilibrada de valor hacia uno de sus agentes: el gobierno.
    La segunda etapa, que abarca el periodo 2000-2003, implica un proceso de reparación del sistema por parte de los operadores para revertir esta transferencia de valor. Este proceso de reparación afecta a todos los agentes en mayor o menor medida.
    Durante el 2003 se ha producido un segundo punto de inflexión mas tenue y aun frágil donde un nuevo aparente equilibrio sienta las bases para una nueva etapa de crecimiento del valor global del sistema económico.

    The Integrated Microphysics and Aerosol Chemistry on Trajectories (IMPACT) model is used to study polar stratospheric cloud (PSC) formation and evolution in the Antarctic vortex. The model is applied to individual air parcel trajectories driven by UK Met Office (UKMO) wind and temperature fields. The IMPACT model calculates the parcel microphysics, including the formation and sedimentation of ice, nitric acid trihydrate (NAT), sulfuric acid tetrahydrate (SAT), and supercooled ternary solution (STS) aerosols. Model results are validated by comparison with data obtained by the Polar Ozone and Aerosol Measurement (POAM) III solar occultation instrument and are examined for 6 years of POAM data (1998-2003). Comparisons of POAM water vapor and aerosol extinction measurements to the model results help to constrain three microphysical parameters influencing the formation and growth of both type I and type II PSCs. Principally, measurements of aerosol extinction prove to be valuable in differentiating model runs; the relationship of aerosol extinction to temperature is determined by the various particle types as they form and grow. Comparison of IMPACT calculations of this relationship to POAM measurements suggests that the initial fraction of nuclei available for heterogeneous NAT freezing is approximately 0.02% of all aerosols. Constraints are also placed on the accommodation coefficient of ice and the NAT-ice lattice compatibility. However, these two parameters have similar effects on the extinction-temperature relationship, and thus a range of values are permissible for each.

    Full Text Available Abstract Background Campylobacter jejuni is a major cause of gastroenteritis worldwide. In Thailand, several strains of C. jejuni have been isolated and identified as major diarrheal pathogens among adult travelers. To study the epidemiology of C. jejuni in adult travelers and U.S. military personnel with acute diarrhea in Thailand from 1998-2003, strains of C. jejuni were isolated and phenotypically identified, serotyped, tested for antimicrobial susceptibility, and characterized using pulsed-field gel electrophoresis (PFGE. Results A total of 312 C. jejuni isolates were obtained from travelers (n = 46 and U.S. military personnel (n = 266 in Thailand who were experiencing acute diarrhea. Nalidixic acid and ciprofloxacin resistance was observed in 94.9% and 93.0% of the isolates, respectively. From 2001-2003, resistance to tetracycline (81.9%, trimethoprim-sulfamethoxazole (57.9%, ampicillin (28.9%, kanamycin (5.9%, sulfisoxazole (3.9%, neomycin (2.0%, and streptomycin (0.7% was observed. Combined PFGE analysis showed considerable genetic diversity among the C. jejuni isolates; however, four PFGE clusters included isolates from the major Lior serotypes (HL: 36, HL: 11, HL: 5, and HL: 28. The PFGE analysis linked individual C. jejuni clones that were obtained at U.S. military exercises with specific antimicrobial resistance patterns. Conclusions In summary, most human C. jejuni isolates from Thailand were multi-resistant to quinolones and tetracycline. PFGE detected spatial and temporal C. jejuni clonality responsible for the common sources of Campylobacter gastroenteritis.

Size-based pollinator exclusion experiments combined with visual observations showed that presence of honey bees (Apis mellifera jemenitica) was...... important for pollination and thereby the production of fruits and seeds. Smaller insects, mainly species of stingless bees (Hypotrigona spp. and Liotrigona cf. bottegoi) and solitary bees (Compsomelissa borneri) could partly compensate pollination in absence of honey bees, but fertilisation and fruit yield...... bees were excluded by bagging. We conclude that local beekeeping with honey bees and stingless bees is likely to have a positive influence on fruit production of shea trees in the farmed West African parklands, which speaks in favour of a pollinator friendly environment....

    Full Text Available Abstract Background Financial barriers are a recognized major bottleneck of access and use of health services. The aim of this study was to assess effectiveness of a community based health insurance (CBHI scheme on utilization of health services as well as on mortality and morbidity. Methods Data were collected from April to December 2007 from the Nouna’s Demographic Surveillance System on overall mortality, utilization of health services, household characteristics, distance to health facilities, membership in the Nouna CBHI. We analyzed differentials in overall mortality and selected maternal health process measures between members and non-members of the insurance scheme. Results After adjusting for covariates there was no significant difference in overall mortality between households who could not have been members (because their area was yet to be covered by the stepped-wedged scheme, non-members but whose households could have been members (areas covered but not enrolled, and members of the insurance scheme. The risk of overall mortality increased significantly with distance to health facility (35% more outside Nouna town and with education level (37% lower when at least primary school education achieved in households. Conclusion There was no statistically significant difference in overall mortality between members and non-members. The enrolment rates remain low, with selection bias. It is important that community based health insurances, exemptions fees policy and national health insurances be evaluated on prevention of deaths and severe morbidities instead of on drop-out rates, selection bias, adverse selection and catastrophic payments for health care only. Effective social protection will require national health insurance.

    Objective: To assess the prevalence of bacterial strains and fungal strains infecting the vaginal tract and test their sensitivity to antibiotics in women attending Saint Camille Medical Centre in Ouagadougou. Methods: From January 2008 to December 2009, a total of 2000 vaginal swabs were cultivated for bacterial and fungal identification and isolation. Furthermore, bacterial strains were tested for their susceptibility to several antibiotics used in routine in the centre.Results:1536/2000 sample, a positivity rate of 76.80%. Candida albicans (48.76%), followed by Escherichiacoli The results revealed that microbial isolation and identification was attempted for (16.67%), Streptococcus agalactiae (8.14%) and Staphylococcus aureus (7.55%) were the major agents of genital tract infections in patients. Mycoplasma hominis and Ureaplasma urealyticum combined accounted for less than 7%. Trichomonas vaginalis was identified in 1.04% cases. The antimicrobial tests revealed that the microorganisms developed resistance to several antibiotics including beta lactams. However, antibiotics such as cefamenzol, ciprofloxacin and norfloxacin were still active on these bacteria. Conclusions: The results reveal that many sexually active women are infected by one or more microbial pathogens, probably because of the lack of hygiene or the adoption of some risky behaviors, such as not using condoms or having multiple sexual partners. Efforts should be made to address these points in the country.

    The aim of the study was to describe the bacterial microflora of diabetic foot infection and to identify the factors which determine the bacterial spectrum in order to increase empiric antibiotic prescription in Ouagadougou. The study was a cross-sectional one, carried from July 1st, 2011 to June 30, 2012 in the departments of internal medicine and general and digestive surgery in Yalgado Ouédraogo teaching hospital. Samples for bacteriological tests consisted of aspiration of pus through the healthy skin, curettage and swab of the base of the ulceration or tissue biopsy from foot lesions. The bacteria's sensitivity to antibiotics has been tested by the qualitative method (Kirby-Bauer). The frequency of diabetic foot infection was 14.45% and the monthly incidence 5.33. The mean age of patients was 56 years and the sex ratio 1.37. Foot ulcerations were chronic in 33 (51.56%), necrotic in 51 (79.69%) and associated with osteitis in 40 (62.5%) patients. Infection was grade 3 in 70.3% cases. Thirty-nine patients had received antibiotics before hospital admission. Among the 71 samples, 62 (87.32%) cultures were positive: 53 (85.48%) monomicrobial and 9 (14.52%) bimicrobial. Aerobic Gram-positive cocci (76%) were the most frequent from ulcerations: Staphylococcus aureus (32.39%), Streptococcus sp (18.30%). Negative coagulase staphylococci have been found in 23.94% cases. Aerobic gram-negative bacilli have been isolated from 24% ulcerations. No factor was associated with the type of bacteria. Gram-positive pathogen cocci showed a high sensitivity to amoxicillin-clavulanic acid and oxacillin. No methicillin-resistant Staphylococcus aureus (MRSA) or extended-spectrum beta lactamase Enterobacteriaceae (ESBL) have been isolated. A better design is necessary to a clarification of bacterial flora in diabetic foot infections. Prevention of bacterial resistance is also needed. PMID:26187771

    Full Text Available Abstract Background In developing countries, most childbirth occurs at home and is not assisted by skilled attendants. The situation increases the risk of death for both mother and child and has severe maternal complications. The purpose of this study was to describe women's perceptions of homebirths in the medical districts of Ouargaye and Diapaga. Methods A qualitative approach was used to gather information. This information was collected by using focus group discussions and individual interviews with 30 women. All the interviews were tape recorded and managed by using QSR NVIVO 2.0, qualitative data management software. Results The findings show that homebirths are frequent because of prohibitive distance to health facilities, fast labour and easy labour, financial constraints, lack of decision making power to reach health facilities. Conclusion The study echoes the need for policy makers to make health facilities easily available to rural inhabitants to forestall maternal and child deaths in the two districts.

    In order to help the hydro-agricultural projects in the management of water resources together with a schistosomiasis control programme, it is important to evaluate the extent of the problem. This is the reason why parasitological and clinical surveys were conducted in schools associated with malacological surveys in transmission sites of several water projects including the one from Sourou. The data-collecting for the research on molluscs was carried out in surface water and as for parasitologic investigations on school-aged children, urine filtration and Kato-Katz were used to evaluate the parasitic load. The levels of prevalence were respectively in Guiédougou, Niassan, Di and Toma-île, in 2000, 60.5%, 40%, 48.8% and 51.9% for the urinary schistosomiasis, 5.3%, 0%, 6.9% and 50.6% for the intestinal schistosomiasis and in 2002, 56%, 51.9%, 51.6% and 43.4% for the urinary schistosomiasis, 10.1%, 8.2%, 22.7% and 90.8% for the intestinal schistosomiasis. The molluscs species collected and identified were: Biomphalaria pfeifferi for the intestinal schistosomiasis and Bulinus truncatus rohlfsi and B. senegalensis for the urinary schistosomiasis. B. senegalensis and B. truncatus were found naturally infested by S. haematobium. Water projects constitute amplifying factors of the proliferation of the species and parasitic exchange. All the actors (developers, populations, scientists) are questioning the means at their disposal to reduce the development of schistosomiasis which decrease the expected benefit of hydro-agricultural installations.

    Acceptability of professional MCH services in the district of Solenzo was assessed using the techniques of time and motion study combined with a user survey of attending mothers. A large proportion of mothers said to have difficulty in using the services. Three types of problems were identified and their relevance discussed: (i) wasting mothers' time through inappropriate opening hours, long waiting time in contrast with short contact time; (ii) organizational features, i.e. fragmentation of clinics offering single MCH components at different times; and (iii) staff behaviour, i.e. poor communication with users. While services do little to help mothers to utilize them, mothers were shown to receive little support in their work at home from their families while attending the clinic. Possible ways to increase acceptability of MCH care are outlined. PMID:2754777

    All over the world meat plays an important role in the nutrition of people. Mostly it is considered to be a special source of strength and health. In many peoples' minds the consumption of animal products, such as muscle, fat, blood, inner organs and bones, is much more associated with vital strength than a vegetarian meal. A reason for this may be the inherent physical similarity between human being and animal, especially mammals. There are other ways of producing meat, such as hunting and f...

    L'objectif de cette étude est de déterminer la fréquence, de décrire les circonstances de découverte, les signes cliniques et paracliniques, la composition chimique des calculs prélevés et les difficultés rencontrées dans le traitement des lithiases urinaires. Notre étude a été rétrospective sur une période de six ans (janvier 2005 à décembre 2010) et a eu pour cadre le CHUP-CDG et a concerné 67 patients âgés de moins de 15 ans opérés pour lithiases urinaires. Les calculs de la dernière année au nombre de douze ont fait l'objet d'une analyse spectrophotométrique. La lithiase urinaire figure parmi les dix premières pathologies du service de chirurgie et représente 1,32% des hospitalisations. L’âge moyen de nos patients est de deux ans et varie de 6 mois à 14 ans. La symptomatologie de la lithiase urinaire est polymorphe. Le diagnostic des lithiases urinaires a été essentiellement radiologique (ASP) dans 87, 50 des cas. Les localisations les plus fréquentes sont: vésicales (49,25%) et pyéliques (46,26%). L'ECBU a révélé une infection urinaire chez 9 patients. Les germes le plus fréquemment rencontrés sont: Klebsiella pneumoniae pneumoniae (22,22%) et staphyloccocus aureus (22,22%). Les difficultés du traitement sont dues à la modicité de nos moyens diagnostiques et à la nature chimique des calculs et le traitement a été dans tous les cas chirurgical. La composition chimique est dominée par les sels calciques notamment les oxalates, les phosphates et les carbonates. PMID:26175840

    Full Text Available High-risk human papillomavirus (HPV is found in over 99% of cervical cancers. The aim of this study was to determine the prevalence of HPV in a population of women in Bobo-Dioulasso and to identify the high-risk types present in these women. From May to June, 2015, 181 women who came for consultation at the Souro Sanou University Hospital of Bobo-Dioulasso have been included in this study. Uterine endocervical swabs have been taken in these women. DNA obtained by extraction from the samples thus collected was used to determine the prevalence of high-risk human papillomavirus genotypes through real-time PCR. The age of the women ranged from 20 to 56 years with a mean of 35.3±8.1 years. The prevalence of infection by high-risk HPV types was 25.4% (46/181. The most common high-risk HPV genotypes were HPV 39 (18.5%, HPV 52 (16.7%, HPV 18 (14.8%, and HPV 35 (13.0%. HPV 16 which is included in the HPV vaccines was not found in the population studied. This type of study which is the first one in Bobo-Dioulasso has showed a high prevalence of genotypes HPV 39, HPV 52, and HPV 35 which are not yet covered by a vaccine.

    Full Text Available The quality and the representativeness of the first long-term Eddy Covariance measurements in the savanna zone of West Africa were investigated using the energy balance closure and the footprint analysis. The quality and representativeness of the first long-term Eddy Covariance measurements over the West African savanna were investigated using the energy balance closure and the footprint analysis. The analysis covered four contrasting periods such as the complete dry season (January to March 2004, the dry to wet transition period (April to May 2004, the rainy season (June to September 2004 and the wet to dry transition period (October to November 2004.

    The results show that the overall energy balance closure can be considered as satisfactory over the whole dataset. The regression fit between (Rn−G and (H+λE was significant (P<0.05 with a coefficient of determination (r2 of 0.80 and a slope of 0.88, while the intercept was 25W/m2. The energy balance closure was affected by rain during the rainy season (r2=0.69, and by sampling problems during the transition periods (R2 were 0.80 and 0.86, respectively.

    The footprint analysis shows that the fetch ranged between 20 m (daytime and 800 m (nighttime. This range showed that the fetch was adequate and fluxes sampled were representative, especially during the rainy season when the vegetal cover was dominated by crops and grasses with scale length of a few meters. During the dry season when the surface is free from crops and grasses, the measurements were also representative as about 60% of the trees around the station were contributing to the measured fluxes. However, during the transition periods some sampling problems appeared, less than 30% of the trees were contributing to the measured fluxes. The relevance of the dominant wind direction in the representativeness of the measurements was also discussed.

  14. Reproductive wastage through slaughtering of pregnant ewe and goat in Quagadougou, Burkina Faso

    International Nuclear Information System (INIS)

    Data collected from 3190 small ruminants (2408 ewe and 782 goats) have been examined after slaughtering, from January to June 2005 in Ouagadougou refrigerated abattoir. 26.70% of sheep and 34.91% of goats were more in advanced gravidity with losses estimated to 0.33 lamb and 0.44 kid per slaughtered sheep and goat. Animals slaughtered during the second half of their gravidity (2-5 months) represented 53.19% of sheep and 58.24% of goats although at this period, the foetus becomes palpable and detectable. This survey attracts the attention on the losses due to the slaughtering of pregnant females, as the deficit in animal proteins doesn't stop worsening. Urgent measures must be considered to decrease the extent of these losses and it is recommended to detect pregnancy females in abattoir and breeders must be trained to simple methods of gestation detection

    Malnutrition is an important indicator of development, and its consequences in children and adolescents produce a serious socioeconomic burden. Children living on the street are more vulnerable than others. Thus, our objective was to analyze the nutritional status of children living on the streets of Manga, through a cross-sectional and analytical study. The snowball technique was used for sampling. Data came from individual interviews, blood samples and medical examinations. Of the 237 children studied, 84.8% were boys; the overall mean age was 11.5 years, and 72.6% were adolescents (aged 10 to 17 years). Growth retardation (15.9%) predominated among the children aged 4 to 9 years, while a weight deficit (27.9%) was most common among those aged 10 to 17. Half of the children (50.2%) with blood tests (N = 119) had anemia. There was a link between anemia and underweight (p = 0.0145). Children who ate at least three times a day were 2.63 times less likely to be anemic (p<0.001). Factors associated with anemia (p<0.005) included survival activities. We frequently found nutritional deficits and anemia in these children. A targeted nutritional program would be a good entry point for their successful reintegration.. PMID:25466289

    The development of cervical cancer is associated with high-risk Human papilloma viruses (HPV-HR). In sub-Saharan Africa cervical cancer is the most common cancer among women and the leading cause of death attributed to malignant tumors. This study aims to identify HPV genotypes within the 30′S and 50′S HPV families found in two previous studies from our laboratory, and to determine the prevalence of twelve HPV-HR genotypes in a population of women in Ouagadougou. The twelve HPV-HR genotypes were determined by real-time multiplex PCR, in 180 samples from the general population and among a group of HIV-1 infected women. The most common genotypes found were HPV-35 (29.4%) and HPV-31 (26.1%) of the 30′S family, and HPV-52 (29.4%) and HPV-58 (20.6%) of the 50′S family. Multiple infections of HPV-HR were observed in 78.03% of infected women. The frequencies of HPV genotypes from the 30′S and 50′S families were higher, while the genotypes HPV-16 and18 were lower among the women in our study. PMID:24106609

    Objective To assess the prevalence of bacterial strains and fungal strains infecting the vaginal tract and test their sensitivity to antibiotics in women attending Saint Camille Medical Centre in Ouagadougou. Methods From January 2008 to December 2009, a total of 2 000 vaginal swabs were cultivated for bacterial and fungal identification and isolation. Furthermore, bacterial strains were tested for their susceptibility to several antibiotics used in routine in the centre. Results The results revealed that microbial isolation and identification was attempted for 1 536/2 000 sample, a positivity rate of 76.80%. Candida albicans (48.76%), followed by Escherichia coli (16.67%), Streptococcus agalactiae (8.14%) and Staphylococcus aureus (7.55%) were the major agents of genital tract infections in patients. Mycoplasma hominis and Ureaplasma urealyticum combined accounted for less than 7%. Trichomonas vaginalis was identified in 1.04% cases. The antimicrobial tests revealed that the microorganisms developed resistance to several antibiotics including beta lactams. However, antibiotics such as cefamenzol, ciprofloxacin and norfloxacin were still active on these bacteria. Conclusions The results reveal that many sexually active women are infected by one or more microbial pathogens, probably because of the lack of hygiene or the adoption of some risky behaviors, such as not using condoms or having multiple sexual partners. Efforts should be made to address these points in the country. PMID:23569916

    High-risk human papillomavirus (HPV) is found in over 99% of cervical cancers. The aim of this study was to determine the prevalence of HPV in a population of women in Bobo-Dioulasso and to identify the high-risk types present in these women. From May to June, 2015, 181 women who came for consultation at the Souro Sanou University Hospital of Bobo-Dioulasso have been included in this study. Uterine endocervical swabs have been taken in these women. DNA obtained by extraction from the samples thus collected was used to determine the prevalence of high-risk human papillomavirus genotypes through real-time PCR. The age of the women ranged from 20 to 56 years with a mean of 35.3 ± 8.1 years. The prevalence of infection by high-risk HPV types was 25.4% (46/181). The most common high-risk HPV genotypes were HPV 39 (18.5%), HPV 52 (16.7%), HPV 18 (14.8%), and HPV 35 (13.0%). HPV 16 which is included in the HPV vaccines was not found in the population studied. This type of study which is the first one in Bobo-Dioulasso has showed a high prevalence of genotypes HPV 39, HPV 52, and HPV 35 which are not yet covered by a vaccine. PMID:27525275

    Full Text Available Abstract Background Malnutrition is still highly prevalent in developing countries. Schoolchildren may also be at high nutritional risk, not only under-five children. However, their nutritional status is poorly documented, particularly in urban areas. The paucity of information hinders the development of relevant nutrition programs for schoolchildren. The aim of this study carried out in Ouagadougou was to assess the nutritional status of schoolchildren attending public and private schools. Methods The study was carried out to provide baseline data for the implementation and evaluation of the Nutrition Friendly School Initiative of WHO. Six intervention schools and six matched control schools were selected and a sample of 649 schoolchildren (48% boys aged 7-14 years old from 8 public and 4 private schools were studied. Anthropometric and haemoglobin measurements, along with thyroid palpation, were performed. Serum retinol was measured in a random sub-sample of children (N = 173. WHO criteria were used to assess nutritional status. Chi square and independent t-test were used for proportions and mean comparisons between groups. Results Mean age of the children (48% boys was 11.5 ± 1.2 years. Micronutrient malnutrition was highly prevalent, with 38.7% low serum retinol and 40.4% anaemia. The prevalence of stunting was 8.8% and that of thinness, 13.7%. The prevalence of anaemia (p = 0.001 and vitamin A deficiency (p Conclusion This study shows that malnutrition and micronutrient deficiencies are also widely prevalent in schoolchildren in cities, and it underlines the need for nutrition interventions to target them.

    Acute viral infections of the central nervous system (CNS) such as acute flaccid paralysis, meningitis, and encephalitis, are responsible for a high morbidity, particularly in children. Non-Polio enteroviruses (NPEV) are known to be responsible for over 80% of viral meningitis in which the etiologic agent is identified. In the present study, we show the frequency of enterovirus meningitis in Brazil from December 1998 to December 2003. Enterovirus were isolated from 162 (15.8%), of a total of 1,022 cerebrospinal fluid (CSF) specimens analyzed. Echovirus 30 was identified in 139 of these isolates (139/162-85.2%). Other identified enteroviruses were: Coxsackievirus B5 (3.7%), Echovirus 13 (3.7%), Echovirus 18 (3%), Echovirus 6 (1.2%), Echovirus 25 (1.2%), Echovirus 1 (0.6%), and Echovirus 4 (0.6%). Patients's age ranged from 28 days to 68 years old. The most frequent symptoms were fever (77%), headache (69.5%), vomiting (71.3%), neck stiffness (41.3%), convulsion (7.1%), and diarrhea (3.7%). Although, the majority of the patients recovered without any complication or permanent squeal, five deaths occurred. Throughout the surveillance period, five viral meningitis outbreaks were confirmed: four in the Southern Brazil and one in the Northeast Brazil. Echovirus 30 was responsible for four out of the five outbreaks while Echovirus 13 caused the fifth one. Besides the outbreaks, 734 sporadic cases were also identified during the study period and 59 of these were positive for virus isolation (8%). Echovirus 30 accounted for 70% of the isolates. Our results showed that Echovirus 30 was the most prevalent etiological agent of viral meningitis in Brazil, causing both outbreaks and sporadic cases. PMID:16299728

    During the DOE Onsite Review in August 1996, Sandia`s Executive Vice President formally proposed combining Sandia`s Institutional Plan and Operating Plan, and their associated processes. The Assistant Secretary for Defense Programs subsequently approved a pilot plan to do so. This pilot plan is intended to comply with one of our new strategic objectives (see section 3.7), which entails creating an infrastructure that is a competitive advantage for our strategic missions. Therefore, Sandia`s planning organization integrated the information in the two plans and collected the data with a unified call. These data can not be combined in multiple ways, depending on customer requirements. Recently, executive management revamped Sandia`s Strategic Plan by creating eight new strategic objectives: four primary whats and four supporting hows. The new strategic objectives are set forth in chapters 3 through 5 of this document. The four primary objectives cover nuclear weapons responsibilities, nonproliferation and materials control, energy and critical infrastructures, and emerging national security threats. The major programmatic initiatives in chapter 7 are grouped accordingly. However, the programmatic descriptions in chapter 6 and the associated funding tables in chapter 9 continue to be presented by DOE Budget and Reporting Code, as in previous Sandia institutional plans. As an aid to the reader, the four primary strategic objectives in chapter 3 are cross-referenced to the program information in chapter 6.

    This Institutional Plan for Argonne National Laboratory contains central elements of Argonne`s strategic plan. Chapter II of this document discusses the Laboratory`s mission and core competencies. Chapter III presents the Science and Technology Strategic Plan, which summarizes key features of the external environment, presents Argonne`s vision, and describes how the Laboratory`s strategic goals and objectives map onto and support DOE`s four business lines. The balance of the chapter comprises the science and technology area plans, organized by the four DOE business lines. Chapter IV describes the Laboratory`s ten major initiatives, which cover a broad spectrum of science and technology. Our proposal for an Exotic Beam Facility aims at, among other things, increased understanding of the processes of nuclear synthesis during and shortly after the Big Bang. Our Advanced Transportation Technology initiative involves working with US industry to develop cost-effective technologies to improve the fuel efficiency and reduce the emissions of transportation systems. The Laboratory`s plans for the future depend significantly on the success of its major initiatives. Chapter V presents our Operations and Infrastructure Strategic Plan. The main body of the chapter comprises strategic plans for human resources; environmental protection, safety, and health; site and facilities; and information management. The chapter concludes with a discussion of the business and management practices that Argonne is adopting to improve the quality and cost-effectiveness of its operations. The structure and content of this document depart from those of the Institutional Plan in previous years. Emphasis here is on directions for the future; coverage of ongoing activities is less detailed. We hope that this streamlined plan is more direct and accessible.

Our research objective was to analyse the effects of three restoration techniques on Jatropha curcas L. seedlings growth and survivorship. We are conducted two separate field trials, involving the sowing and planting of J. curcas, in which several different soil restoration techniques were applied. The trial was monitored using a randomized block study design over a period of two years. The design included ten different treatments, six in the sowing trial and four in the planting trial, each with three replicates. In the first experiment, growth rate was found to be significantly higher in the Sub-Soiling treatment, that received additional organic matter than other treatments. However, overall survival rate was low (18%. In the second experiment, the Half-moon treatment yielded a significantly higher growth both in height (df = 3, F = 56.74, p < 0.05 and diameter (df = 3, F = 31.76, p < 0.05 and survival rate compared to those of the other treatments (df = 3, F = 50.4, p < 0.05. In conclusion, planting seedlings produced a greater survival rate than sowing seeds. Among the soil restoration and water conservation techniques tested in this study, the Half-moon technique was found to be the most effective. This is recommended to be used for improving the revegetation of J. curcas in the future.

    Full Text Available Background: One promising way to improve the motivation of healthcare providers and the quality of healthcare services is performance-based incentives (PBIs also referred as performance-based financing. Our study aims to explore healthcare providers’ preferences for an incentive scheme based on local resources, which aimed at improving the quality of maternal and child health care in the Nouna Health District. Design: A qualitative and quantitative survey was carried out in 2010 involving 94 healthcare providers within 34 health facilities. In addition, in-depth interviews involving a total of 33 key informants were conducted at health facility levels. Results: Overall, 85% of health workers were in favour of an incentive scheme based on the health district's own financial resources (95% CI: [71.91; 88.08]. Most health workers (95 and 96% expressed a preference for financial incentives (95% CI: [66.64; 85.36] and team-based incentives (95% CI: [67.78; 86.22], respectively. The suggested performance indicators were those linked to antenatal care services, prevention of mother-to-child human immunodeficiency virus transmission, neonatal care, and immunization. Conclusions: The early involvement of health workers and other stakeholders in designing an incentive scheme proved to be valuable. It ensured their effective participation in the process and overall acceptance of the scheme at the end. This study is an important contribution towards the designing of effective PBI schemes.

    Dengue is a re-emerging arboviral disease in tropical countries. Haemorrhagic form may be associated with circulatory failure and produce hypovolemic shock, which is often fatal. We report a series of three cases of hemorrhagic dengue observed at the Infectious Diseases Department CHU Yalgado Ouédraogo, Ouagadougou, in order to describe its epidemiological, clinical, and evolutive characteristics. Our study included young females who had an onset age of between 35 years and 45 years, residing in the city of Ouagadougou. Despite multiple concentrated platelets transfusions and symptomatic treatment, we mourned a death. The development of antivirals and of new vaccines is a silver lining to prevent dengue lethality.

    Full Text Available The adoption of Artemisinin based combination therapies (ACT constitutes a basic strategy for malaria control in sub-Saharan Africa. Moreover, since cases of ACT resistance have been reported in South-East Asia, the need to understand P. falciparum resistance mechanism to ACT has become a global research goal. The selective pressure of ACT and the possibility that some specific Pfcrt and Pfmdr1 alleles are associated with treatment failures was assessed in a clinical trial comparing ASAQ to AL in Nanoro. Dried blood spots collected on Day 0 and on the day of recurrent parasitaemia during the 28-day follow-up were analyzed using the restriction fragments length polymorphism (PCR-RFLP method to detect single nucleotide polymorphisms (SNPs in Pfcrt (codon76 and Pfmdr1 (codons 86, 184, 1034, 1042, and 1246 genes. Multivariate analysis of the relationship between the presence of Pfcrt and Pfmdr1 alleles and treatment outcome was performed. AL and ASAQ exerted opposite trends in selecting Pfcrt K76T and Pfmdr1-N86Y alleles, raising the potential beneficial effect of using diverse ACT at the same time as first line treatments to reduce the selective pressure by each treatment regimen. No clear association between the presence of Pfcrt and Pfmdr1 alleles carried at baseline and treatment failure was observed.

  13. Modelling radionuclides transport and dose assessment in groundwater system in Somita-Taparko Goldmine in Burkina Faso

    International Nuclear Information System (INIS)

    Radionuclides transport and dose assessment to the public in a groundwater system are described using theoretical and experimental methods. It is known that radionuclides could accumulate during mining and mineral ore processing and reach into water bodies, and thus contribute to the radiation dose received by the public who consume this water. As groundwater is inaccessible, a mathematical model with a numerical method is used to describe the relevant physical processes during radionuclide transport in the groundwater system. A computer programme has been written in MatLab to implement the numerical solution. The activity concentration and annual committed effective dose to the public from natural radionuclides (NORM) are determined for both theoretical and experimental methods. The NORM elements of interest are 238U, 232Th and 40K. The results obtained from the study revealed that the concentration of NORM in Taparko groundwater system increases with time at the point of release and becomes constant at a certain time. The concentration then decreases rapidly as far as from the release point. The average activity concentrations for theoretical method were 0.3 Bq/L, and 0.05 Bq/L for 238U and 232Th respectively at 600 m from the discharged point where the water from boreholes and wells is used by the public. For experimental analysis the mean activity concentrations were 5.57 Bq/L, 0.58Bq/L and 4.78 Bq/L for 238U, 232Th and 40K respectively. The corresponding average annual committed effective doses estimated were 0.13mSv/y, 0.28 mSv/y, for theoretical and experimental methods respectively. The theoretical and experimental results indicate insignificant exposure of the public to Natural Occurring Radioactive Materials (NORM) from the activities of the Goldmine. (au)

    The adoption of Artemisinin based combination therapies (ACT) constitutes a basic strategy for malaria control in sub-Saharan Africa. Moreover, since cases of ACT resistance have been reported in South-East Asia, the need to understand P. falciparum resistance mechanism to ACT has become a global research goal. The selective pressure of ACT and the possibility that some specific Pfcrt and Pfmdr1 alleles are associated with treatment failures was assessed in a clinical trial comparing ASAQ to AL in Nanoro. Dried blood spots collected on Day 0 and on the day of recurrent parasitaemia during the 28-day follow-up were analyzed using the restriction fragments length polymorphism (PCR-RFLP) method to detect single nucleotide polymorphisms (SNPs) in Pfcrt (codon76) and Pfmdr1 (codons 86, 184, 1034, 1042, and 1246) genes. Multivariate analysis of the relationship between the presence of Pfcrt and Pfmdr1 alleles and treatment outcome was performed. AL and ASAQ exerted opposite trends in selecting Pfcrt K76T and Pfmdr1-N86Y alleles, raising the potential beneficial effect of using diverse ACT at the same time as first line treatments to reduce the selective pressure by each treatment regimen. No clear association between the presence of Pfcrt and Pfmdr1 alleles carried at baseline and treatment failure was observed. PMID:27031231

    Averting women's pregnancy-related death is today recognised as an international health and development priority. Maternal survival is, in this sense, a success story. There is, however, little research into what happens to the women who survive the severe obstetric complications that are the main causes of maternal mortality. This paper examines findings from repeated in-depth interviews with 64 women who survived a clinically defined 'near-miss.' These interviews were conducted as part of a...

    Full Text Available The purpose of this investigation was to elucidate the anti-nociceptive and anti-inflammatory properties of aqueous acetone extracts from Cienfuegosia digitata Cav; and Sida Alba L. in Swiss mice, with an aim to provide a scientific basis for the traditional use of these plants in the treatment of inflammation disorders. In anti-inflammatory activity, the carrageenan-induced paw edema and oil croton-induced ear edema in Swiss mice. As for analgesic effects, acetic acid writhing and formalin test methods were used in mice. About anti-inflammatory potential, the extracts at doses of 100; 200 and 400 mg/kg body weight produced significant comparatively to the control groups (p<0.05; p<0.01 and p<0.001 and we noticed a dose-dependent anti-inflammatory activity. The dose-dependent inhibition of edema was observed at 1; 2 and 3 h. However, extracts showed dose-dependent inhibition of croton oil induced ear oedema, at doses of 200; 300 and 500 µg/ear. As for analgesic activity, extracts produced significant analgesic effects in acetic acid writhing and formalin test method (p<0.05; p<0.01 and p<0.001 compared to the control groups and a dose-dependent inhibition was observed. The present study concludes that Cienfuegosia digitata Cav. and Sida Alba L. have anti-inflammatory and analgesic properties.
