Air quality observations in the major cities of South-Western Africa still remains few with regards to economic growth and the large increase in the urban population. The main cities lying on the Gulf of Guinea experiences low air quality because of the contribution of local emissions and advection of pollutants from the African continent. We present in this paper new observations acquired from February 2015 to March 2017 in the major cities of Cotonou (Bénin) and Abidjan (Côte d'Ivoire). The PM2.5 mass concentration and carbon composition (elemental and organic carbon) were recorded on a weekly basis at 4 different locations representative of major emission sources, i.e. traffic emission, domestic fire and waste burning. Additionally, the aerosol optical depth (AOD) was also recorded daily inside and outside the cities. We observe large similarly between both cities. The mean PM2.5 concentration of around 30 µg.m-3 is coherent with previous studies for sub-Saharan western Africa and is 3 times higher than the concentrations recommended by the World Health Organization. The sampled collected at the domestic fire site shows a large pollution by smoking activity with an average concentration of 145 µg.m-3, nearly 5 times the traffic background. The seasonality of PM2.5 is affected by the contribution of desert dust and biomass burning emissions that is clearly observed from the AOD time series. We observe that dust events contribute sporadically to large amount of PM2.5, above 100 µg.m-3, during the dry seasons. Moreover, the biomass burning activity is also maximum before and during the dry season and contributes to increase the PM2.5 concentration. Low PM2.5 observed during the minor dry season can be explain by an enhancement of the atmospheric dispersion due to the increase in the wind intensity and the absence of biomass burning activity. We observe a significant difference in the carbonaceous aerosols between the traffic site in Abidjan and Cotonou. The

Since 2008, several outbreaks of yellow fever and dengue occurred in Abidjan, the economic capital of Côte d'Ivoire. A better knowledge of the biology of Aedes aegypti populations, the main vector of yellow fever and dengue viruses, is necessary to tailor vector control strategies implemented in the city. This study was designed to determine some biological parameters, occurring during the life cycle of two morphological phenotypes of Ae. aegypti larvae. Mosquitoes were sampled in a suburb of Abidjan (Treichville) using the WHO layer-traps technique. Biological parameters were studied in laboratory under standard conditions of temperature (27°C ± 2°C) and relative humidity (80% ± 10%). Our results indicated that the mean eggs laid by females from 'brown larvae' (BL) (85.95, 95% confidence interval (CI 95%) 78.87-93.02) was higher than those from 'white larvae' (WL) (64.40%, CI 95% 55.27-73.54). The gonotrophic cycle was 3 and 4 days in females from BL and WL, respectively. The overall yield of breeding mosquitoes from BL (63.88%, CI 95% 62.61-65.14) was higher compared with those of mosquitoes from WL (59.73%, CI 95% 58.35-61.12). The sex ratio (male/female) was 0.95 and 1.68 in Ae. aegypti populations from BL and WL, respectively. Females from BL lived slightly longer than those from WL (t = -2.332; P = 0.021). This study shows that Ae. Aegypti populations from BL and WL present different biological parameters during their life cycle. This could have an implication on their ability to transmit human disease viruses such as dengue and yellow fever. Further molecular studies are needed to determine genetic divergence between these Ae. aegypti populations.

Radon as natural gas is permanently present in our environment. It is the main natural radiological exposure source for human beings. So, the study of the concentration of this rare gas is essential in order to evaluate the risks incured by the population and the environment. The results of different studies will guide as to take the appropriate protection decisions as recommended by the World Health Organization (WHO). The present work consists in measuring the concentration of radon (Rn 222 isotope) in seven (7) pre-selected sites in the city of Cocody (Abidjan) using SSNTD/LR-115 (photographic film detectors). Our measurements showed some variations in the concentration of radon according to seasons and the influence of main factors such as the porosity, humidity and the diameter of the specks of soil. We noticed that our measured values remain very low compared to international standards. This work is the first step for more important measurements throughout the whole ivorian territory. The aim is to draw a national cartography of radon in Cote d'Ivoire. [fr

In April 2008, Abidjan was again faced with another case of yellow fever after the epidemic of 2001 causing mass immunization campaign. In order to evaluate the extent of amaril virus circulation and the risk for local people, an entomological investigation was carried out by the Ministry of Health and Public Hygiene of Côte d'Ivoire. At "Entent" area of Treichville, Breteau index was estimated at 34, recipient index at 20% and house index at 25%. Those indexes were respectively 53, 21 and 31% at "Vridi canal" of Port Bouet. In the both neighborhood, Aedes aegypti accounted for more than 80% of mosquitoes caught and more than 90% of mosquitoes adults obtained from larval breeding. This new situation of epidemic risk could be explained by several factors including the reception of 70% of forced migration people caused by the crisis in the country occurred in 2002, the probable drop of preventive immunization, the environment deterioration creating of more breeding sites of Ae. aegypti.

An Antigen ELISA (Ag-ELISA) detecting circulating antigens of trypanosomes was evaluated in the central region of Cote d'Ivoire for the serodiagnosis of cattle trypanosomosis. Of 1423 sera examined, only 43 were positive in the MHCT/BCT, 105 (7%) were detected using stained blood smears, and 74 (5%) were found positive using the Ag-ELISA. The predominant trypanosome species was T. brucei, being present in 84% of the positive samples as detected by the BCT, in 96% using stained bloodsmears, and in 72% by Ag-ELISA. T.vivax was detected less frequently. The serological (ELISA) test did not detect all positive animals as found by the haematological techniques. However, the two techniques should be used in a complementary way to improve the diagnosis of the disease. The results confirm that the prevalence of trypanosomes in cattle is low in the study area. The low prevalence can be due to prophylaxis and therapy of livestock in combination with successful tsetse trapping. (author). 4 refs, 2 figs, 4 tabs

The financial burden of morbidity in HIV-infected adults on antiretroviral therapy in Cote d'Ivoire.

Directory of Open Access Journals (Sweden)

Arnousse Beaulière

Full Text Available BACKGROUND: Large HIV care programs frequently subsidize antiretroviral (ARV drugs and CD4 tests, but patients must often pay for other health-related drugs and services. We estimated the financial burden of health care for households with HIV-infected adults taking antiretroviral therapy (ART in Côte d'Ivoire. METHODOLOGY/PRINCIPAL FINDINGS: We conducted a cross-sectional survey. After obtaining informed consent, we interviewed HIV-infected adults taking ART who had consecutively attended one of 18 HIV care facilities in Abidjan. We collected information on socioeconomic and medical characteristics. The main economic indicators were household capacity-to-pay (overall expenses minus food expenses, and health care expenditures. The primary outcome was the percentage of households confronted with catastrophic health expenditures (health expenditures were defined as catastrophic if they were greater than or equal to 40% of the capacity-to-pay. We recruited 1,190 adults. Median CD4 count was 187/mm(3, median time on ART was 14 months, and 72% of subjects were women. Mean household capacity-to-pay was $213.7/month, mean health expenditures were $24.3/month, and 12.3% of households faced catastrophic health expenditures. Of the health expenditures, 75.3% were for the study subject (ARV drugs and CD4 tests, 24.6%; morbidity events diagnosis and treatment, 50.1%; transportation to HIV care centres, 25.3% and 24.7% were for other household members. When we stratified by most recent CD4 count, morbidity events related expenses were significantly lower when subjects had higher CD4 counts. CONCLUSIONS/SIGNIFICANCE: Many households in Côte d'Ivoire face catastrophic health expenditures that are not attributable to ARV drugs or routine follow-up tests. Innovative schemes should be developed to help HIV-infected patients on ART face the cost of morbidity events.

Air quality degradation is a major issue in the large conurbations on the shore of the Gulf of Guinea. We present for the first time PM2.5 time series collected in Cotonou, Benin, and Abidjan, Côte d'Ivoire, from February 2015 to March 2017. Measurements were performed in the vicinity of major combustion aerosol sources: Cotonou/traffic (CT), Abidjan/traffic (AT), Abidjan/landfill (AL) and Abidjan/domestic fires (ADF). We report the weekly PM2.5 mass and carbonaceous content as elemental (EC) and organic (OC) carbon concentrations. We also measure the aerosol optical depth (AOD) and the Ångström exponent in both cities. The average PM2.5 mass concentrations were 32 ± 32, 32 ± 24 and 28 ± 19 µg m-3 at traffic sites CT and AT and landfill site AL, respectively. The domestic fire site shows a concentration of 145 ± 69 µg m-3 due to the contribution of smoking and roasting activities. The highest OC and EC concentrations were also measured at ADF at 71 ± 29 and 15 ± 9 µg m-3, respectively, while the other sites present OC concentration between 8 and 12 µg m-3 and EC concentrations between 2 and 7 µg m-3. The OC / EC ratio is 4.3 at CT and 2.0 at AT. This difference highlights the influence of two-wheel vehicles using gasoline in Cotonou compared to that of four-wheel vehicles using diesel fuel in Abidjan. AOD was rather similar in both cities, with a mean value of 0.58 in Cotonou and of 0.68 in Abidjan. The seasonal cycle is dominated by the large increase in surface mass concentration and AOD during the long dry season (December-February) as expected due to mineral dust advection and biomass burning activities. The lowest concentrations are observed during the short dry season (August-September) due to an increase in surface wind speed leading to a better ventilation. On the other hand, the high PM2.5 / AOD ratio in the short wet season (October-November) indicates the stagnation of local pollution.

HIV vulnerability and the erasure of sexual and gender diversity in Abidjan, Côte d'Ivoire.

2016-01-01

In the fight against concentrated HIV epidemics, men who have sex with men (MSM) are often framed as a homogeneous population, with little attention paid to sexual and gender diversity and its impact on HIV vulnerability. This article draws on ethnographic research conducted in Abidjan, Côte d'Ivoire among les branchés - a local term encompassing several categories of same-sex desire and practice. In the context of increased HIV prevention programming targeting Ivoirian sexual and gender minorities, such diversity is effectively erased. This obfuscation of difference has particularly negative impacts for travestis, who may be at higher risk for HIV infection, though research and prevention efforts in which they are grouped with 'MSM' render them underrepresented and make their vulnerability difficult to quantify. Branchés whose class and/or ethnic backgrounds compound their stigmatised status as sexual and gender minorities also bear the burden of this exclusion. Furthermore, some branchés deploy 'MSM' as a form of self-identification, further complicating who such categories represent. By highlighting the ways in which constructions of gender and sexuality within HIV/AIDS programming obscure complex social realities, I aim to reorient thinking around the development of purposeful HIV programming that engages the complexity of sexual and gender minority experience.

Men who have sex with men (MSM) are at high risk of HIV. Few data are available on MSM and HIV-related risk behaviors in West Africa. We aimed to describe risk behaviors and vulnerability among MSM in Abidjan, Cote d′Ivoire. We conducted a cross-sectional respondent-driven sampling survey with 601 MSM in 2011–2012. Sociodemographic and behavioural data as well as data related to emotional state and stigma were collected. Population estimates with 95% confidence intervals were produced. Survey weighted logistic regression was used to assess factors associated with inconsistent condom use in the prior 12 months. Most MSM were 24 years of age or younger (63.9%) and had attained at least primary education (84.4%). HIV risk behaviors such as low condom and water-based lubricant use, high numbers of male and female sex partners, and sex work were frequently reported as well as verbal, physical and sexual abuse. Inconsistent condom use during anal sex with a male partner in the prior 12 months was reported by 66.0% of the MSM and was positively associated with history of forced sex, alcohol consumption, having a regular partner and a casual partner, having bought sex, and self-perception of low HIV risk. MSM in Abidjan exhibit multiple and frequent HIV-related risk behaviors. To address those behaviours, a combination of individual but also structural interventions will be needed given the context of stigma, homophobia and violence. PMID:24959923

2014-01-01

The decentralization of healthcare services is becoming increasingly important in strategies of public sector management. This concept is analyzed from various points of view, including legal, economic, political, and sociological. Several typologies have been proposed in the literature to analyze this decentralization process, which can take different forms ranging from simple deconcentration to more elaborate devolution. In some instances, decentralization can be analyzed by the degree of autonomy given to local authorities. This article applies these typologies to analyze the healthcare system decentralization process in Cote d'Ivoire. Special attention is paid to the new forms of community healthcare organizations. These decentralized structures enjoy a kind of autonomy, with characteristics closer to those of devolution. The model might serve as an example for population involvement in defining and managing healthcare problems in Cote d'Ivoire. We end with proposals for the improvement of the process.

Violence is a human rights violation, and an important measure in understanding HIV among female sex workers (FSW). However, limited data exist regarding correlates of violence among FSW in Côte d'Ivoire. Characterizing prevalence and determinants of violence and the relationship with structural risks for HIV can inform development and implementation of comprehensive HIV prevention and treatment programs. FSW > 18 years were recruited through respondent driven sampling (RDS) in Abidjan, Côte d'Ivoire. In total, 466 participants completed a socio-behavioral questionnaire and HIV testing. Prevalence estimates of violence were calculated using crude and RDS-adjusted estimates. Relationships between structural risk factors and violence were analyzed using χ tests and multivariable logistic regression. The prevalence of physical violence was 53.6% (250/466), and sexual violence was 43.2% (201/465) among FSW in this study. Police refusal of protection was associated with physical (adjusted Odds Ratio [aOR]: 2.8; 95% confidence interval [CI]: 1.7 to 4.4) and sexual violence (aOR: 3.0; 95% CI: 1.9 to 4.8). Blackmail was associated with physical (aOR: 2.5; 95% CI: 1.5 to 4.2) and sexual violence (aOR: 2.4; 95% CI: 1.5 to 4.0). Physical violence was associated with fear (aOR: 2.2; 95% CI: 1.3 to 3.1) and avoidance of seeking health services (aOR: 2.3; 95% CI: 1.5 to 3.8). Violence is prevalent among FSW in Abidjan and associated with features of the work environment and access to care. These relationships highlight layers of rights violations affecting FSW, underscoring the need for structural interventions and policy reforms to improve work environments, and to address police harassment, stigma, and rights violations to reduce violence and improve access to HIV interventions.

Rapid urbanization is a key driver of the unique set of health risks facing urban populations. One of the most critical health hazards facing urban women is intimate partner violence (IPV). In post-conflict urban areas, women may face an even greater risk of IPV. Yet, few studies have examined the IPV experiences of urban-dwelling, conflict-affected women, including those who have been internally displaced. This study qualitatively examined the social and structural characteristics of the urban environment that contributed to the IPV experiences of women residing in post-conflict Abidjan, Côte d'Ivoire. Ten focus groups were conducted with men and women, both internally displaced (IDPs) and non-displaced. Lack of support networks, changing gender roles, and tensions between traditional gender norms and those of the "modern" city were reported as key contributors to IPV. Urban poverty and with it unemployment, food insecurity, and housing instability also played a role. Finally, IDPs faced heightened vulnerability to IPV as a result of displacement and discrimination. The relationship between economic strains and IPV are similar to other conflict-affected settings, but Abidjan's urban environment presented other unique characteristics contributing to IPV. Understanding these factors is crucial to designing appropriate services for women and for implementing IPV reduction interventions in urban areas. Strengthening formal and informal mechanisms for help-seeking, utilizing multi-modal interventions that address economic stress and challenge inequitable gender norms, as well as tailoring programs specifically for IDPs, are some considerations for IPV program planning focused on conflict-affected women in urban areas.

To report on the results of three size estimations of the populations of female sex workers (FSW) in five cities in Côte d'Ivoire and on operational lessons learned, which may be relevant for key population programmes in other parts of the world. We applied three methods: mapping and census, capture-recapture and service multiplier. All were applied between 2008 and 2009 in Abidjan, San Pedro, Bouaké, Yamoussoukro and Abengourou. Abidjan was the city with the highest number of FSW by far, with estimations between 7880 (census) and 13 714 (service multiplier). The estimations in San Pedro, Bouaké and Yamoussoukro were very similar, with figures ranging from 1160 (Yamoussoukro, census) to 1916 (San Pedro, capture-recapture). Important operational lessons were learned, including strategies for mapping, the importance of involving peer sex workers for implementing the capture-recapture and the identification of the right question for the multiplier method. Successful application of three methods to estimate the population size of FSW in five cities in Côte d'Ivoire enabled us to make recommendations for size estimations of key population in low-income countries. © 2017 John Wiley & Sons Ltd.

To evaluate the attitude of pregnant women towards HIV testing in two cities of West Africa: Abidjan, Côte d'Ivoire and Bobo-Dioulasso, Burkina Faso. In the context of a clinical trial to prevent HIV vertical transmission, HIV counselling and testing was offered systematically to women attending antenatal clinics. Informed consent was obtained and test results were given anonymously. Multiple logistic regression was performed to identify factors associated with refusal for testing and failure to return for test results. A total of 9724 pregnant women were interviewed from January 1995 to September 1996. In Abidjan (n=5766) and Bobo-Dioulasso (n=3958), 78 and 92.4% of the women consented to HIV testing, respectively, and 58.4 and 81.8% of them returned for the test results disclosure, respectively. In the two sites, the counsellors themselves and high educational level of the women appeared to be related to refusal of the test, whereas last trimester gestation was associated with failure to return for test results. In Abidjan, foreigners and employees were more likely to refuse testing, and HIV-infected women were three times less likely to return for results than uninfected women. Future implementation of interventions to reduce vertical transmission of HIV that require antenatal HIV testing and counselling will have to solve issue of acceptability of HIV testing by pregnant women.

Stroke characteristics in Sub-Saharan Africa (SSA) differ from developed countries. However, SSA subjects undergo epidemiological and demographic transition and it appears that the prevalence of vascular risk factors (RF) increases in this population. Here we aimed to compare stroke patients' characteristics between a SSA hospital (Cocody University Hospital, Abidjan, Côte d'Ivoire) and a French stroke unit (Amiens University Hospital, Amiens, France). This retrospective study included all consecutive stroke patients admitted between January and May 2008 (Cocody University Hospital, Abidjan, Côte d'Ivoire) and between October and December 2008 (Amiens University Hospital, Amiens, France). We assessed each patient's demographic details, RF, and CT confirmed pathological stroke type. The glomerular filtration rate (GFR) was estimated using the four-component Modification of Diet in Renal Disease (MDRD) equation and CKD was defined as a GFR less than 60ml/min/1.73 m(2). One hundred and ninety five patients were included (Amiens: 92; Abidjan: 103) with a mean age of 63±14 years. Patients in Amiens had more known vascular RF than African patients, whereas African patients had more RF discovered during hospitalisation. Furthermore, CKD was significantly more common in SSA patients (43% vs 24%, P=0.001). More African than European patients had cerebral hemorrhage (34% vs 8%, Pstroke mortality and treatments at hospital discharge were similar between the two hospitals. Finally, a high proportion of patients in Abidjan suffered from cervical atherosclerosis, although it was significantly lower than patients in Amiens (37% vs 67%, Pstroke patients. These findings could partly explain the high prevalence of cervical atherosclerosis found in this population. These results warrant confirmation in prospective studies.

.4 and 2.9E-8 and 2.48E-5 m/s, respectively. These values of permeability are low. They were therefore multiplied by 10 in order to calibrate the model. This suggests that the environment of deposition of the sands is heterogeneous with coarse sand channels in places as it can be expected in such lagoon environment. The result of the model simulation in steady state indicates the groundwater flow direction (North-South) and the approach of pollutants plumes to some well fields after 20 years. References: Deh S.

In high HIV prevalence resource-constrained settings, exclusive breastfeeding with early cessation is one of the conceivable interventions aimed at the prevention of HIV through breast milk. Nevertheless, this intervention has potential adverse effects, such as the inappropriateness of complementary feeding to take over breast milk. The purpose of our study first was to describe the nature and the ages of introduction of complementary feeding among early weaned breastfed infants up to their first birthday and second was to assess the nutritional adequacy of these complementary foods by creating a child feeding index and to investigate its association with child nutritional status. A prospective cohort study in Abidjan, Côte d'Ivoire, was conducted in HIV-infected pregnant women who were willing to breastfeed and had received a perinatal antiretroviral prophylaxis. They were requested to practice exclusive breastfeeding and initiate early cessation of breastfeeding from the fourth month to reduce breast milk HIV transmission. Nature and ages of introductory complementary feeding were described in infants up to their first birthday by longitudinal compilation of 24-hour and 7-day recall histories. These recalls were done weekly until 6 weeks of age, monthly until 9 months of age, and then quarterly. We created an index to synthesize the nutritional adequacy of infant feeding practices (in terms of quality of the source of milk, dietary diversity, food, and meal frequencies) ranging from 0 to 12. The association of this feeding index with growth outcomes in children was investigated. Among the 262 breastfed children included, complete cessation of breastfeeding occurred in 77% by their first birthday, with a median duration of 4 months. Most of the complementary foods were introduced within the seventh month of life, except for infant food and infant formula that were introduced at age 4 months. The feeding index was relatively low (5 of 12) at age 6 months, mainly

Africa bears a quarter of the global burden of disease but contributes less than 2% of the global research publications on health, partially due to a lack of expertise and skills to carry out scientific research. We report on a short course on research methods organised by the Clinical Research Education Networking and Consultancy (CRENC) during the third international congress of the Ivorian Cardiac Society (SICARD) in Abidjan, Cote d'Ivoire. Results from the pre- and post-test evaluation during this course showed that African researchers could contribute more to scientific research and publications, provided adequate support and investment is geared towards the identification and training of motivated early-career scientists.

This study was carried in the intensive care units of Abidjan university hospitals and in the herpetology department of Pasteur Institute between January 2001 and April 2003. The purpose was to identify ophidian species that were dangerous for man and to document cases of snakebite in Abidjan. The study was carried out in two phases, i.e., collection and identification of snake species followed by review of case records involving snake envenomation at Cocody and Treichville university hospitals. A total of 5 snake families, 14 genera and 17 species including some that were dangerous for man were identified. All species except Naja nigricollis live in forest areas. Most snakebites led to simple clinical signs that regressed within 72 hours with only symptomatic treatment. However, a few cases required immunotherapy. Traditional methods of snakebite treatment were used for first line treatment in 50% of cases.

The determination of the geological age of the uraninite of Ivory Coast in particular, has a very big importance since it permits to date the granito-gneissic basement of this part of Africa and moreover it is one of the most former known uraninites. The emotion caused in some geologists surroundings by the announcement of the date, fixed to close to 2 billions of years for this part of Africa, incited us to make control our assessment by the isotope analysis of lead. Before the concordance really astonishing of the results gotten by two entirely different methods, the publication of our works could not be differed more. The geological age of the uraninite of Coast of Ivory determined to the Laboratory of Mineralogy is of 1933 millions of years: by the calculation given with the help of the logarithmic and based shape on the chemical analysis of the uraninite (precise dosages of U, Pb and Th); by the isotope analysis, this age is about: 1940 {+-} 20 millions of years. We conducted the same operations for several French pitchblendes as the Crousille, Bauzot, Bigay. (M.B.)

Few centers for open heart surgery (OHS) are in Sub-Saharan Africa. Lack of OHS results is also noted. By reporting our African experience on OHS, the aim of this study was to fill the gap. It is a retrospective study on 2,612 patients who were subject to an OHS between 1978 and 2013. Data were collected from demographical, clinical, investigative studies, surgical and outcomes parameters. There were 1,475 cases of rheumatic heart diseases (RHD), 126 endomyocardial fibrosis (EMF), 741 congenital heart diseases (CHDs) and 270 various affections. Related to rheumatic valvular surgery we enumerated 1,175 monovalvular (mitral n=778, aortic n=336, tricuspid n=61); 280 bivalvular (mitral + aortic n=150, mitral + tricuspid n=130) and 20 trivalvular. For RHD, average age was 26±10.1 years (4-69 years) and 60% of our patients presented a functional class III or IV according to New York Heart Association (NYHA) classification. A total of 1,481 valvular replacements (bioprostheses n=489, mechanical prostheses n=992) and 445 valvular repair were carried out with a global and late mortality surgery respectively at 7% and 8%. One hundred and twenty-six [126] cases of EMF with right sided form 39, left sided form 40, and bilateral form 47 were colligated. Average age was 12±0.6 years (2-15 years). All patients with EMF underwent surgery; an endocardectomy in all patients combined with valvular reconstruction (n=36) or valvular replacement (n=90) was carried out with a hospital mortality at 16% (n=20). Concerning CHD, the most frequent were ventricular septal defect (VSD) (n=240), atrial septal defect (ASD) (n=200), partial atrio-ventricular sepal defect (n=30) and tetralogy of Fallot (T4F) (n=220), a total correction was performed for those CHD with an early mortality at 6.4% (n=44). OHS in Cote d'Ivoire was successfully performed in most of our patients, the spectrum of acquired valvular heart diseases and CHDs in our country is similar to others in Sub-Saharan Africa.

Millions of people are already affected by weather-related shocks every year in West Africa and climate change is highly likely to increase these threats. In the wake of climate change, rising temperatures, increasingly irregular rainfall and more frequent natural hazards will endanger the ways of life of vulnerable population groups in this region and destabilize their human security. A surge in violence and conflicts could take place. One of the conflict constellations could be between farmers and herders. These groups are highly vulnerable to climate change due to their dependence on natural resources Millions of people are already affected by weather-related shocks every year in West Africa and climate change is highly likely to increase these threats. In the wake of climate change, rising temperatures, increasingly irregular rainfall and more frequent natural hazards will endanger the ways of life of vulnerable population groups in this region and destabilize their human security. A surge in violence and conflicts could take place. One of the conflict constellations could be between farmers and herders. These groups are highly vulnerable to climate change due to their dependence on natural resources for their subsistence. Furthermore, they are historically prone to enter into conflict over issues of access to natural resources. However, social, economic and political circumstances fundamentally influence environmental conflicts. There might thus be opportunities to face the societal challenges of climate change in a peaceful way and the political and institutional framework could play an important role in reducing conflict and violence. In order to explore such a path, this study analyses the potential of political factors (policies and institutions) for the reduction of climate-change-induced or aggravated conflicts between farmers and herders.

Full Text Available Abstract Background Clinical evolution of HIV-infected children who have not yet initiated antiretroviral treatment (ART is poorly understood in Africa. We describe severe morbidity and mortality of untreated HIV-infected children. Methods All HIV-infected children enrolled from 2004-2009 in a prospective HIV programme in two health facilities in Abidjan, Côte d'Ivoire, were eligible from their time of inclusion. Risks of severe morbidity (the first clinical event leading to death or hospitalisation and mortality were documented retrospectively and estimated using cumulative incidence functions. Associations with baseline characteristics were assessed by competing risk regression models between outcomes and antiretroviral initiation. Results 405 children were included at a median age of 4.5 years; at baseline, 66.9% were receiving cotrimoxazole prophylaxis, and 27.7% met the 2006 WHO criteria for immunodeficiency by age. The risk of developing a severe morbid event was 14% (95%CI: 10.7 - 17.8 at 18 months; this risk was lower in children previously exposed to any prevention of mother-to-child-transmission (PMTCT intervention (adjusted subdistribution hazard ratio [sHR]: 0.16, 95% CI: 0.04 - 0.71 versus those without known exposure. Cumulative mortality reached 5.5% (95%CI: 3.5 - 8.1 at 18 months. Mortality was associated with immunodeficiency (sHR: 6.02, 95% CI: 1.28-28.42. Conclusions Having benefited from early access to care minimizes the severe morbidity risk for children who acquire HIV. Despite the receipt of cotrimoxazole prophylaxis, the risk of severe morbidity and mortality remains high in untreated HIV-infected children. Such evidence adds arguments to promote earlier access to ART in HIV-infected children in Africa and improve care interventions in a context where treatment is still not available to all.

Barriers to HIV testing in Cote d'Ivoire: the role of individual characteristics and testing modalities.

Full Text Available BACKGROUND: Expanding HIV testing requires a better understanding of barriers to its uptake. We investigated barriers to HIV testing in Côte d'Ivoire, taking into account test circumstances (client vs. provider-initiated. METHODS: We used data from the 2005 nationally representative Demographic and Health Survey conducted in Côte d'Ivoire. Socio-demographic characteristics, sexual behaviour and knowledge and attitudes toward HIV/AIDS associated with recent (<2 years HIV testing were identified using gender-specific univariate and multivariate logistic regressions. Among women, differential effects of barriers to testing according to test circumstance (whether they have been offered for a prenatal test or not were assessed through interaction tests. RESULTS: Recent HIV testing was reported by 6.1% of men and 9.5% of women (including 4.6% as part of antenatal care. Among men, having a low socioeconomic status, having a low HIV-related knowledge level and being employed [compared to those inactive: adjusted Odds Ratio (aOR 0.46; 95% confidence interval (CI 0.25-0.87] were associated with lower proportions of recent HIV testing. Among women without a prenatal HIV testing offer, living outside the capital (aOR 0.38; CI 0.19-0.77 and reporting a unique lifetime sexual partner constituted additional barriers to HIV testing. By contrast, among women recently offered to be tested in prenatal care, none of these variables was found to be associated with recent HIV testing. CONCLUSIONS: Various dimensions of individuals' characteristics constituted significant barriers to HIV testing in Côte d'Ivoire in 2005, with gender specificities. Such barriers are substantially reduced when testing was proposed in the framework of antenatal care. This suggests that provider-initiated testing strategies may help overcome individual barriers to HIV testing.

Alcohol consumption is both a health and social risk factor. Few studies have been conducted on alcohol use among students in Côte d'Ivoire. This study was designed to determine factors associated with alcohol consumption among secondary school students in Côte d'Ivoire. A cross-sectional study was conducted in May 2011 among public secondary school students in Abidjan. One class for each year of study was randomly selected. Multivariate analysis was conducted between alcohol consumption and independent variables. A total of 316 students participated in the survey. The mean age (SD) of the study population was 16.1 (2.7) years. One hundred and fourteen respondents (36.1%) reported having already drunk alcohol. Age of first alcohol consumption was 10-14 years among girls (48.8%) and 15-19 years among boys (49.3%). Multivariate logistic regression identified the following factors associated with alcohol use among students: Christian religion, more pocket money, living with parents who drink alcohol and the student's perception of alcohol as a refreshing drink or having an antidepressant effect. In the light of the determinants of alcohol consumption and the students'suggestions in our study, it appears essential to involve students in actions concerning alcohol abuse.

This work is part of the DACCIWA FP7 project (Dynamics-Aerosol-Chemistry-Cloud Interactions in West Africa) in the framework of the Work Package 2 Air Pollution and Health. This study aims to characterize urban air pollution levels through the measurement of NO2, SO2, NH3, HNO3 and O3 in Abidjan, the economic capital of Côte d'Ivoire. Measurements of inorganic gaseous pollutants, i.e. NO2, SO2, NH3, HNO3 and O3 were performed in Abidjan during an intensive campaign within the dry season (15 December 2015 to 16 February 2016), using INDAAF (International Network to study Deposition and Atmospheric chemistry in AFrica) passive samplers exposed in duplicate for 2-week periods. Twenty-one sites were selected in the district of Abidjan to be representative of various anthropogenic and natural sources of air pollution in the city. Results from this intensive campaign show that gas concentrations are strongly linked to surrounding pollution sources and show a high spatial variability. Also, NH3, NO2 and O3 gases were present at relatively higher concentrations at all the sites. NH3 average concentrations varied between 9.1 ± 1.7 ppb at a suburban site and 102.1 ± 9.1 ppb at a domestic fires site. NO2 mean concentration varied from 2.7 ± 0.1 ppb at a suburban site to 25.0 ± 1.7 ppb at an industrial site. Moreover, we measured the highest O3 concentration at the two coastal sites of Gonzagueville and Félix-Houphouët-Boigny International Airport located in the southeast of the city, with average concentrations of 19.1 ± 1.7 and 18.8 ± 3.0 ppb, respectively. The SO2 average concentration never exceeded 7.2 ± 1.2 ppb over all the sites, with 71.5 % of the sampling sites showing concentrations ranging between 0.4 and 1.9 ppb. The HNO3 average concentration ranged between 0.2 and 1.4 ppb. All these results were combined with meteorological parameters to provide the first mapping of gaseous pollutants on the scale of the district of Abidjan using geostatistical analysis

Gamassa Pascal Kany Prud’ome

2017-01-01

Full Text Available Abidjan port-hinterland is composed of three countries which include Ivory Coast, Mali and Burkina Faso. The fast economic growth of the above countries resulted to a greater demand for the foreign goods from their population, causing a congestion problem at Abidjan port. Because of this problem, the connectivity movement between the port and its hinterland has considerably slowed down. In this article a qualitative methodology is used to analyse the Abidjan port-hinterland connectivity. The constant delays of the train services, the road congestion and the lack of coordination and communication between Abidjan port and its hinterland customers are the main presented challenges. The results of this research demonstrate that the poor quality roads and railways and the lack of a new dry port in Ivory Coast greatly affects the fluidity of the Abidjan port-hinterland connectivity. This article suggests some strategies on how to solve the current challenges and will be helpful in deciding on how the Abidjan port should be developed better and improve its connectivity with its hinterland.

Full Text Available Study of rattan production-to-consumption system in the district of Abidjan (South Côte d’Ivoire. The domestication of Non-Wood Forest Products (NWFP requires an evaluation of their social and economical potentials in the target zones. The present work deals with this problematic in the district of Abidjan (South Côte d’Ivoire in order to suggest for this zone, a community-based forest management plan, allowing a conservation and sustainable exploitation of rattan, used as plant model. From interviews and printed forms addressed to 42 rural families composed of about 200 persons, 30 rattan collectors, 12 rattan raw stems traders, 187 craftsmen distributed among 60 workroom and ten urban families (about 70 persons we determine the commercial channels and evaluate the economic profit of rattan exploitation for each social category involved. We also note the different problems encountered by rattan operators. Data show that rattan trade is profitable at both rural and urban levels, suggesting that this plant should be a NWFP biological model for the implementation of rural forests management and sustainable exploitation program. Then we showed that the exploitation of 250 bunches used for furniture production generated a global income equalled 2830 or 2877 US $ according to harvester (farmer or collector from town. Of this global income, 375US $ (13.03% are owned by farmers, 696 (24.59% by harvesters, 929 (32.39% or 561 (19.82% by canes wholesalers, and 1573 (54.67 or 55.58%, according the case by craftsmen. Nevertheless, many legislative, institutional, and logistic constraints threat presently the stability and expansion of rattan industry. From obtained data, suggestions are made either for forests management and sustainable exploitation strategies and a best organisation of rattan channels.

This study examines the impact of two decades of neoliberal policy reform on food production and household livelihood security in three West African countries. The rice sectors in The Gambia, Côte d'Ivoire, and Mali are scrutinized as well as cotton and its relationship to sorghum production in Mali. Although market reforms were intended to improve food production, the net result was an increasing reliance on imported rice. The vulnerability of the urban populations in The Gambia and Côte d'Ivoire became especially clear during the 2007-2008 global food crisis when world prices for rice spiked. Urban Mali was spared the worst of this crisis because the country produces more of its own rice and the poorest consumers shifted from rice to sorghum, a grain whose production increased steeply as cotton production collapsed. The findings are based on household and market surveys as well as on an analysis of national level production data.

Paragonimiasis is a neglected tropical disease caused by an infection with lung flukes that is transmitted through the consumption of undercooked crabs. The disease is often confused with tuberculosis. Paragonimiasis is thought to be endemic in south-western Côte d'Ivoire. Two cross-sectional surveys were carried out in the first half of 2009 in patients attending two tuberculosis centres of Abidjan. A third cross-sectional survey was conducted in May 2010 in children of two primary schools in Dabou, where crabs are frequently consumed. Patients with chronic cough provided three sputum samples plus one stool sample. Sputum samples were examined for tuberculosis with an auramine staining technique and for Paragonimus eggs using a concentration technique. Stool samples were subjected to the Ritchie technique. Schoolchildren provided a single stool sample, and samples were subjected to the Kato-Katz and an ether-concentration technique. A pre-tested questionnaire was administered to patients and schoolchildren to investigate food consumption habits. Additionally, between June 2009 and August 2010, shellfish were purchased from markets in Abidjan and Dabou and examined for metacercariae. No human case of paragonimiasis was diagnosed. However, trematode infections were seen in 32 of the 272 shellfish examined (11.8%). Questionnaire results revealed that crab and pig meat is well cooked before consumption. Among the 278 patients with complete data records, 62 had tuberculosis, with a higher prevalence in males than females (28.8% vs. 13.9%, χ2 = 8.79, p = 0.003). The prevalence of helminths and intestinal protozoa was 4.6% and 16.9%, respectively. In the school survey, among 166 children with complete data records, the prevalence of helminths and intestinal protozoa was 22.3% and 48.8%, respectively. Boys had significantly higher prevalences of helminths and intestinal protozoa than girls. Hookworm was the predominant helminth species and Entamoeba coli was the most

Enteropathogenic Yersinia circulate in the pig reservoir and are the third bacterial cause of human gastrointestinal infections in Europe. In West Africa, reports of human yersiniosis are rare. This study was conducted to determine whether pathogenic Yersinia are circulating in pig farms and are responsible for human infections in the Abidjan District. From June 2012 to December 2013, pig feces were collected monthly in 41 swine farms of the Abidjan district. Of the 781 samples collected, 19 Yersinia strains were isolated in 3 farms: 7 non-pathogenic Yersinia intermedia and 12 pathogenic Yersinia enterocolitica bioserotype 4/O:3. Farm animals other than pigs and wild animals were not found infected. Furthermore, 2 Y. enterocolitica 4/O:3 strains were isolated from 426 fecal samples of patients with digestive disorders. All 14 Y. enterocolitica strains shared the same PFGE and MLVA profile, indicating their close genetic relationship. However, while 6 of them displayed the usual phage type VIII, the other 8 had the highly infrequent phage type XI. Whole genome sequencing and SNP analysis of individual colonies revealed that phage type XI strains had unusually high rates of mutations. These strains displayed a hypermutator phenotype that was attributable to a large deletion in the mutS gene involved in DNA mismatch repair. This study demonstrates that pathogenic Y. enterocolitica circulate in the pig reservoir in Côte d'Ivoire and cause human infections with a prevalence comparable to that of many developed countries. The paucity of reports of yersiniosis in West Africa is most likely attributable to a lack of active detection rather than to an absence of the microorganism. The identification of hypermutator strains in pigs and humans is of concern as these strains can rapidly acquire selective advantages that may increase their fitness, pathogenicity or resistance to commonly used treatments.

A prospective study was carried out from 2010 to 2012 at the Hôpital Général d'Abobo (HGA) in Abidjan, in order to determine the impact of infectious and parasitic diseases on child cognitive development. Blood samples were examined by means of thick drop and blood smear; as for stool by direct examination and concentration by formalin-ether method. We evaluated the prevalence, the parasite load of malaria and gastrointestinal parasites; then we investigated the risk factors for these disorders. Overall, 331 pregnant women in the last trimester of their pregnancy were enrolled. The plasmodic index was 3.9% with infestation specific rates of P. falciparum from 100%. Concerning digestive protozoa, it has been observed 71.3% of nonpathogenic, against 9.7 % of pathogens, either an overall prevalence of 51.4% of digestive parasites. The calculated average parasitic loads revealed 3089.2 tpz/μl of blood (95 % CI: 591.1-5587.3) for malaria, 6.5 eggs per gram of stool (95 % CI: 0.4-13.4) for intestinal helminths and one parasite by microscopic field for protozoa (common infestation). It has been shown that the occurrence of malaria has been linked to the non-use of impregnated mosquito nets (x 2 = 0.012; p = 0.018), not to age. No link could be established between the presence of digestive parasites and the age of pregnant women, or socioeconomic conditions (level of education, profession, type of toilet). Malaria is less common in pregnant women while the rate of digestive parasites remains high.

Full Text Available In the agenda towards malaria eradication, assessment of both malaria exposure and efficacy of anti-vectorial and therapeutic strategies is a key component of management and the follow-up of field interventions. The simultaneous use of several antigens (Ags as serological markers has the potential for accurate evaluation of malaria exposure. Here we aimed to measure the longitudinal evolution of the background levels of immunity in an urban setting in confirmed clinical cases of malaria.A retrospective serological cross-sectional study on was carried out using 234 samples taken from 2010 to 2013 in peri-urban sentinel facility of Cote d'Ivoire. Antibody responses to recombinant proteins or BSA-peptides, 8 Plasmodium falciparum (PfAMA1, PfMSP4, PfMSP1, PfEMP1-DBL1α1-PF13, PfLSA1-41, PfLSA3-NR2, PfGLURP and PfCSP, one P. malariae (PmCSP and one Anopheles gambiae salivary (gSG6-P1 antigens were measured using magnetic bead-based multiplex immunoassay (MBA. Total anti- P. falciparum IgG responses against schizont lysate from african 07/03 strain (adapted to culture and 3D7 strain was measured by ELISA.High prevalence (7-93% and levels of antibody responses to most of the antigens were evidenced. However, analysis showed only marginal decreasing trend of Ab responses from 2010 to 2013 that did not parallel the reduction of clinical malaria prevalence following the implementation of intervention in this area. There was a significant inverse correlation between Ab responses and parasitaemia (P<10-3, rho = 0.3. The particular recruitment of asymptomatic individuals in 2011 underlined a high background level of immunity almost equivalent to symptomatic patients, possibly obscuring observable yearly variations.The use of cross-sectional clinical malaria surveys and MBA can help to identify endemic sites where control measures have unequal impact providing relevant information about population immunity and possible decrease of transmission.

Objectives: to assess the knowledge of users and health professionals about the risks of irradiation of the pregnant woman in the course of radiological examinations and the application of rules of radiation protection to pregnant women by X-ray users. Materials and Methods: our prospective study, conducted at the University Hospital of Yopougon, lasted 6 months. We interviewed 60 women who were pregnant or likely to be, 30 non-radiologist prescribing physicians, 29 medical imaging technicians and 21 health care aides on radiation risk and protective measures for pregnant women before and during the implementation of a radiological examination using X-rays. Results: 73.7% of prescribing physicians have no knowledge of radiation protection in women who are pregnant or of childbearing age. 93.1% of patients who are pregnant or of childbearing age were not aware of X-rays in diagnostic radiology and the harm they pose to a pregnant or potentially pregnant woman. 80% of radiology manipulators do not respect the basic rules of radiation protection. Conclusion: greater awareness of the users of X-ray radiation risks in pregnancy or women likely to be pregnant is required at the University Hospital of Yopougon. (authors)

Full Text Available Acute kidney injury (AKI in the elderly is characterized by high mortality. The objective of this study is to identify the causes of death in the elderly with AKI. This is a prospective cohort study with a descriptive purpose which was carried out during the period from January 2009 to December 2014 in the Department of Nephrology-Internal Medicine of Treichville University Hospital. The diagnosis of AKI was made on the basis of serum creatinine (SCr values determined during hospitalization, according to KDIGO classification. Our study involved 107 elderly aged 65 and older with AKI. The hospital mortality rate was 46.7% (50/107. The average age of deceased patients was 71.8 ± 7 years with extremes of 65 and 90 years. We observed a male predominance with a sex ratio (41/9 of 4.55. AKI on admission was in Stage 1 in 16% of cases, in Stage 2 in 24%, and in Stage 3 in 60% cases. SCr was normal in 8%, the AKI was in Stage 1 in 34% (P = 0.09, Stage 2 in 18% (P = 0.001, and Stage 3 in 40% (P = 0.0001. AKI in deceased patients was organic in 36% of cases, obstructive in 30%, and functional in 6%. The etiologies of AKI were infections (46%, cancer (18%, benign tumors of the urinary tract (12%, malignant hypertension (6%, decompensated heart disease (6%, and drugs (6%. The main causes of death were sepsis (28%, cardiovascular disease (22%, severe renal failure (20%, pelvic cancers (16%, and liver failure (12%. All patients with cancer (P = 0.001 or HIV infected (P = 0.009 died. Sixty-eight percent of deaths occurred the 1st week. Death was earlier by sepsis and cardiovascular disease than by cancer. Mortality is high in the elderly. The main causes of death were sepsis, cardiovascular disease, renal failure, pelvic cancer, and liver failure.

In Côte d'Ivoire, the prevalence of malnutrition among children younger than 5 years exceeded 5% in 2011 and was thus considered serious. This overall prevalence may nonetheless mask differences and specificities between regions and municipalities. This study sought to determine the prevalence and risk factors of malnutrition among children in this age group in a semi-urban area of Abidjan. This exhaustive, descriptive, cross-sectional survey took place from May 6 to July 31, 2010. The children's nutritional status was determined according to the WHO criteria. Univariate and multivariate analysis of factors associated with malnutrition (social and demographic characteristics, immunization status, children's eating practices, and household characteristics) were studied. We visited 668 households and recruited 809 children. The prevalence of malnutrition was 22.5%. Multivariate analysis showed that the introduction of porridge after 6 months halved the risk of malnutrition. Risk tripled for children whose father's occupation did not guarantee a regular income. Among the factors highlighted by this study, dietary practices seem the most amenable to corrective action. For example, the adoption of outreach programs by the Maternal and Child Protection services could improve nutritional practices in households.

Groundwater as natural resources is one of the main sources of water for agricultural, industrial and domestic in developed or developing countries. However this resource, which was considered of good quality, is now threatened by various sources of contamination by human activities. This is the case of the District of Abidjan which has been the victim of toxic waste in 2006 and of an alpine valley in Western Switzerland. Groundwater from these two sites is located in sandy and unconfined aquifers. In fact, the pollutant transport in porous media is influenced by a variety of physical, chemical or biological, complex and interdependent. In Switzerland, where data are available, we simulated steady-state flow and tetrachloroethene transport with a good result showing the tetrachloroethene plume. While in Abidjan, where the data are insufficient, we developed in steady and transient states, flow and contaminants transport models in order to predict the likely evolution of the contaminants in the basement. Contaminants are composed of a very high contents of hydrogen sulfide, organochlorines, sulfur, mercaptan sulfur, and hydrocarbons such as olefins, Paraffins. We made two parametric and comparative studies. The probability of contamination of groundwater is observed over time, taking into account the input parameters of the model and some assumptions.

Epidemiological studies associate air pollution, especially particulate, increased morbidity and mortality from respiratory and cardiovascular origin . Africa, which has an urbanization rate among the highest in the world, is particularly exposed. The 'Initiative on the air quality in Sub-Saharan Africa' showed the importance of atmospheric concentrations of certain pollutants such as nitrogen oxides, sulfur dioxide and particulate matter (PM{sub 10}). Like the great capitals of Africa, Abidjan, economic capital and most industrialized city of Ivory Coast is facing an air pollution from industrial-urban and health consequences for its population of nearly 6 million inhabitants. To better understand the mechanisms of action resulting from pulmonary exposure to particulate atmospheric aerosols, we proposed: (i) to collect atmospheric particles (PM{sub 2.5}) using high volume cascade impaction in the District of Abidjan in three influences (rural, urban or industrial), (ii) to determine their main physicochemical, (iii) assess their cytotoxicity and their role in the induction of oxidative damage in a model of human lung cells (A549) in culture. The chemical composition of the atmospheric particles revealed their heterogeneity, and many inorganic (e.g. Al, Ca, Fe, Mn, Zn, Ni, Cr, Cu, Pb, Mg) and organic compounds (e.g. paraffins) were quantified at the three sites. Their effect concentrations (EC) to 10 and 50% on the A549 were as follows: influence rural: EC{sub 10} = 5.91 {mu}g/cm{sup 2} and EC{sub 50} 29.55 {mu}g/cm{sup 2}, urban influence: EC{sub 10} = 5 .45 {mu}g/cm{sup 2} and EC{sub 50} = 27.23 {mu}g/cm{sup 2}, and industrial influence: EC{sub 10} = 6.86 {mu}g/cm{sup 2} and EC{sub 50} = 34.29 {mu}g/cm{sup 2}. Exposure of A549 cells to Abidjan city's PM samples for 24, 48 or 72 hours to their EC{sub 10} or EC{sub 50} induced oxidative damage, as demonstrated by the formation of malon-dialdehyde, changes in enzyme activity of superoxide dismutase

Urban development and employment in Abidjan.

The city of Abidjan in the Ivory Coast has grown physically, economically, and demographically at rates exceeding all reasonable expectation. Yet, as in many other development nations, the employment generated by Abidjan's rapid economic expansion has failed to keep pace with the increase in working population it has attracted. Consequently, economic success has been accompanied by a variety of social strains. Some of these have been discussed in earlier issues of the "International Labour Review" by Louis Roussel. This discussion expands on Roussel's earlier treatment by focusing more specifically on several facets of the urban employment problem created by the rapid growth of Abidjan. Attention is directed to labor supply and employment, factors affecting migration, foreign Africans in the Ivory Coast labor force; the urban informal sector; urban infrastructure and development; social problems of population pressure; employment policy options (current government policies and other policy options); and general issues and policy alternatives (motivations for rural urban migration, smaller urban centers as alternative growth poles, and distributing the gains from development). Several essential features of the employment problem stem from the rural urban distribution of the workforce. The rural labor force, including temporary seasonal workers from the savannah countries to the north, remains more or less in balance with increasing rural employment opportunities, since the migration of Ivory Coast nationals to the cities is balanced by the inflow of foreign workers. In contrast, the influx of migrants into urban areas has led to a more rapid increase in the urban labor force than in urban employment, with a consequent rise in unemployment. In 1970 the Abidjan rate of open unemployment was probably around 20%. At this time, most people's idea of a desirable job is one in the formal sector of the urban economy. If there is to be any hope of an eventual balance between

HIV and STI prevalence among female sex workers in Côte d'Ivoire: why targeted prevention programs should be continued and strengthened.

Full Text Available OBJECTIVE: To assess condom use and prevalence of STIs and HIV among female sex workers (FSWs, as part of a comprehensive monitoring and evaluation plan of a nationwide sex worker prevention project in Côte d'Ivoire. DESIGN AND METHODS: Cross sectional surveys were conducted among FSWs attending five project clinics in Abidjan and San Pedro (2007, and in Yamoussoukro and Gagnoa (2009. A standardized questionnaire was administered in a face-to-face interview, which included questions on socio-demographic characteristics, sexual behaviour and condom use. After the interview, the participants were asked to provide samples for STI and HIV testing. RESULTS: A total of 1110 FSWs participated in the surveys. There were large differences in socio-demographic and behavioural characteristics between FSW coming for the first time as compared to FSW coming on a routine visit. The prevalence of N. gonorrhoeae or C.trachomatis was 9.1%, 11.8% among first vs. 6.9% routine attendees (p = 0.004. The overall HIV prevalence was 26.6%, it was lower among first time attendees (17.5% as compared to 33.9% for routine attendees, p<0.001. The HIV prevalence among first attendees was also lower than the proportion of HIV positive tests from routine testing and counselling services in the same clinics. CONCLUSIONS: The results show a relatively high STI and HIV prevalence among FSWs in different cities in Côte d'Ivoire. In the light of these results, prevention efforts should continue to focus on FSWs in the country.

The Timing of cotE Expression Affects Bacillus subtilis Spore Coat Morphology but Not Lysozyme Resistance▿

The synthesis of structural components and morphogenetic factors required for the assembly of the Bacillus subtilis spore coat is governed by a mother cell-specific transcriptional cascade. The first two temporal classes of gene expression, which involve RNA polymerase sigma σE factor and the ancillary regulators GerR and SpoIIID, are deployed prior to engulfment of the prespore by the mother cell. The two last classes rely on σK, whose activation follows engulfment completion, and GerE. The cotE gene codes for a morphogenetic protein essential for the assembly of the outer coat layer and spore resistance to lysozyme. cotE is expressed first from a σE-dependent promoter and, in a second stage, from a promoter that additionally requires SpoIIID and that remains active under σK control. CotE localizes prior to engulfment completion close to the surface of the developing spore, but formation of the outer coat is a late, σK-controlled event. We have transplanted cotE to progressively later classes of mother cell gene expression. This created an early class of mutants in which cotE is expressed prior to engulfment completion and a late class in which expression of cotE follows the complete engulfment of the prespore. Mutants of the early class assemble a nearly normal outer coat structure, whereas mutants of the late class do not. Hence, the early expression of CotE is essential for outer coat assembly. Surprisingly, however, all mutants were fully resistant to lysozyme. The results suggest that CotE has genetically separable functions in spore resistance to lysozyme and spore outer coat assembly.

Full Text Available The phenomenon of “microbes” gangs tends to spread throughout the territory of Abidjan district, but especially to increase the number of victims. The objective of this study is to determine the criminal acts perpetrated by the “microbes” and show how this phenomenon is experienced in populations. The methodology is based on desk and field research with the population. The qualitative analysis allowed to highlight crime and insecurity within the population. The results highlighted the fact that the multiple aggressions of “microbes”, both violent and recurrent, led to numerous injuries and even death of the victims. Also, they contributed to the establishment of a feeling of insecurity among the population of Abidjan. Le phénomène des gangs de « microbes » a tendance à s’étendre sur l’ensemble du territoire du district d’Abidjan, mais surtout à accroître le nombre des victimes. L’objectif de cette étude est de déterminer les actes criminels perpétrés par les « microbes » et de montrer comment ce phénomène est vécu au sein des populations. La méthodologie est basée sur une recherche documentaire et de terrain auprès des populations. L’analyse qualitative a permis de mettre en évidence la criminalité et le sentiment d’insécurité au sein de la population. Les résultats ont mis en exergue le fait que les multiples agressions des « microbes », à la fois violentes et récurrentes, ont conduit à de nombreux blessés voire décès des victimes. Aussi, ont-ils concouru à l’instauration d’un sentiment d’insécurité au sein des populations abidjanaises.

Buruli ulcer is currently a major public health problem in Côte d'Ivoire. It is a neglected tropical disease closely associated with aquatic environments. Aquatic insects of the Hemiptera order have been implicated in human transmission of Mycobacterium ulcerans, the pathogenic agent of Buruli ulcer. The purpose of this preliminary study using the polymerase chain reaction (PCR) method was to evaluate aquatic insects in Sokrogbo, a village in the Tiassalé sanitary district where Buruli ulcer is endemic. Findings identified two water bugs hosting Mycobacterium ulcerans, i.e., one of the Micronecta genus in the Corixidae family and another of the Diplonychus genus in the Belostomatidae family. The PCR technique used revealed the molecular signatures of M. ulcerans in tissue from these two insects. Based on these findings, these two water bugs can be considered as potential hosts and/or vectors of M. ulcerans in the study zone. Unlike Diplonychus sp., this is the first report to describe Micronecta sp as a host of M. ulcerans. Further investigation will be needed to assess the role of these two water bugs in human transmission of M. ulcerans in Côte d'Ivoire.

Hepatitis B and HIV infection are two viral infections that represent real global public health problems. In order to improve their management, some hypotheses suggest that genetic predispositions like ABO and Rh blood groups would influence the occurrence of these diseases. The aim of the present study was to examine the association between ABO and Rhesus blood groups and the susceptibility to HIV infection and hepatitis B. We conducted a cross-sectional and analytical study in a population of voluntary blood donors in the Blood Transfusion Center of Abidjan. All blood donors who donated blood between January and June 2014 were tested for HBs antigen and anti-HIV antibodies (ELISA tests) and were ABO typed. The total number of examined blood donors during this period was 45,538, of which 0.32% and 8.07% were respectively infected with HIV and hepatitis B virus. O-group donors were more infected than non-O donors. Our study is an outline concerning the search for a link between ABO and Rh blood groups and hepatitis B and HIV infection. Further studies should be conducted to confirm the interaction between these two infections and contribute to the search for new therapeutic approaches.

Four countries, Botswana, Cote d'Ivoire, Ghana and Zimbabwe, were chosen as cases to study the impact of national health policies on national health status in sub-Saharan Africa. Through a conceptual framework that covers health problem identification, policy formulation and implementation procedures, the study examined national translations of Primary Health Care (PHC) and Health for All by the Year 2000 (HFA/2000) strategies. A series of government measures, taken between 1980-1986 for health policy development and implementation in these countries, were treated as policy determinants of national health outcomes for the period ending 1990. The impact of these determinants on national health status was then analyzed through a comparative description and documentation of observable patterns and trends in infant mortality rates (IMR), under-5 mortality rates (U5MR) and life expectancy. Policy guidelines from PHC and HFA/2000 were used in conjunction with the respective per capita Gross National Products to categorize the four cases. Based on these guidelines, Botswana was ranked high, both in terms of policy development and the level of economic development, while Zimbabwe ranked high in terms of policy development but relatively low in economic terms. Cote d'Ivoire ranked high on economic development but low with regard to its policy framework. Ghana was at the other end of the spectrum, ranking low both in terms of its policy development and its economic performance. The comparative analysis revealed that Botswana and Zimbabwe performed better than Cote d'Ivoire and Ghana on the three outcome indicators. Despite Cote d'Ivoire's superior level of economic development, its health status fell behind that of Zimbabwe and even Ghana. The study concluded that policies formulated and implemented in accordance with key PHC principles could account for improvements in national health status. Since the end of the study period (1990), there have been significant political

We described the use of antiretroviral drugs to prevent HIV transmission among children and adolescents victims of rape in Abidjan (Ivory Coast). We conducted a retrospective and descriptive study on children (0-9 years) and adolescents (10-19 years) victims of rape between 2000 and 2013. We analyzed the patients' socio-demographic characteristics and the modality of the chemoprophylaxis. We included 10 children and 89 adolescents in the study. The median age was 16 years old (3-19 years). The median time to consultation was 23.5 hours (5-152 hours). The antiretroviral chemoprophylaxis was administered to 92 patients (93%). No HIV and HBV seroconversion was observed after a 3-month follow-up. A better management of rape victims is required in Abidjan. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

The association between youths' sexual and reproductive attitudes and behaviors and those of their peers and parents has been documented; however, information on siblings' influence is scarce, especially for developing countries. Data on 1,395 female and 1,242 male survey respondents aged 15-24 from three cities in Côte d'Ivoire were analyzed. Life-table analysis was conducted to examine respondents' probability of remaining sexually inexperienced according to siblings' history of premarital childbearing. Cox multivariate regressions were used to estimate respondents' relative risks of sexual debut by age 17 and by age 24. At any age between 15 and 24 years, the life-table probability of remaining sexually inexperienced was typically lower among persons who had at least one sibling with a premarital birth than among those who had no such sibling. In general, among those with at least one sibling who had had a premarital birth, the probability was lower if the sibling or siblings and the respondent were of the same gender rather than opposite genders, and the probability was lowest among those who had a brother and a sister with a history of premarital childbearing. In the multivariate analysis for males, having one or more brothers only, or having at least one brother and at least one sister, with a history of premarital childbearing was associated with increased relative risks of being sexually experienced by ages 17 and 24. No such association was found for females. Programs that seek to reduce premarital sexual activity among young people should develop strategies that take into account the potential influence of siblings.

The sacroiliac joint remains unknown in sub-Saharan Africa. Studies about the sacroiliac diseases are rare Aim : Describe the epidemiological, clinical, radiological and etiological characteristics of sacroiliac joint diseases in Abidjan Methods : Retrospective and descriptive study concerning 17 patients hospitalized from February 2003 to April 2010 in the department of rheumatology of university hospital center of Cocody (Abidjan) for buttock pain or others functional signs evoking sacroiliac joint which were attested by radiographic lesions. We were interested on the epidemiological, clinical and radiological characteristics and the etiologies in the sacroiliac disease. The hospital prevalence of sacroiliac diseases was 0.55% corresponding in 17 of 3067 rheumatological diseases. The female sex predominated (82.35%) and the mean age of 25.58 years. Gyneco-obstetric events were the predominant risk factors (47.05%). Sacroiliac damage was manifested by inflammatory pain (64.7%) localized at the buttock or lumbar spine, radiating to the thigh (52.9%) and was accompanied by functional disability (82.2%) and fever was not present every time (64.7%). The physical findings were the tripod sign positive (58.8%), the monopodal backing positive (41.2%) and palpation painful of sacroiliac joint. The standard radiograph revealed a blurring aspect and widening of joint space associated with demineralization (68.4%), a joint space narrowing and erosion of articular banks (23.5%). The etiologies found were bacterial arthritis (82.3%) mainly pyogenic (70.58%), osteoarthritis (11.7%) and ankylosing spondylitis (5.9%). Sacroiliac joint diseases are rare in rheumatology practice in Abidjan, concern younger subjects and are dominated by pyogenic sacroiliitis.

1992-07-01

The composites Simpson's rule is extended to n-dimensional integrals with variable limits. This extension is illustrated by means of the recursion relation of n-fold series. The structure of calculation by the Newton-Cotes formulas for n-dimensional integrals is clarified with this method. A quadrature formula corresponding to the Newton-Cotes formulas can be readily constructed. The results computed for some examples are given, and the error estimates for two or three dimensional integrals are described using the error term. (author)

Amandine Henry

2013-03-01

Full Text Available Cet article traite de l’inégalité d’accès aux services publics urbains dans les pays en développement et, plus particulièrement, de la question de l’accès au service d’enlèvement des ordures ménagères à Abidjan. Cette question est étroitement liée au mouvement de centralisation, décentralisation et recentralisation qui a affecté la gestion de ce service au cours des dernières décennies. Chaque étape de l’avancée de la Côte d’Ivoire dans le processus de décentralisation a provoqué des changements institutionnels dans la gestion des ordures ménagères à Abidjan ; tous ont eu des effets spécifiques sur l’accès de la population à ce service. Ces effets sont étudiés à l’échelle des communes et des quartiers à travers une enquête de terrain, et sont liés aux caractéristiques socio-économiques des quartiers. Une analyse comparative entre deux communes de standing opposé, ainsi que l’examen des aspects historiques de la problématique, s’attachent à identifier les facteurs-clés d’une telle inégalité d’accès au service d’enlèvement des ordures ménagères à Abidjan.This paper deals with the inequality of access to the urban public utilities in developing countries, and more accurately with the issue of the access to the waste collection in Abidjan. This question is closely linked with the centralization, decentralization and recentralization movements that affected this service management for the last decades. Each stage of the decentralization process in Ivory Coast brought institutional changes in waste collection management in Abidjan. Each of them had specific consequences on the access of people to this service. These consequences are investigated on a local scale and are linked to the socio-economic characteristics of the studied areas. Together with the focus on the historical aspects of the problematic, a comparative analysis between two districts of opposite standing attempts

With more than 6 million inhabitants, Abidjan district faces tremendous difficulties in water supply. The aquifer of the Continental Terminal which is actually the only drinking water source of the city shows a decline of resources and water demand is increasing due to the population growth. Moreover significant evidences of chemical and biological pollution of the groundwater are observed The Aghien lagoon, the largest freshwater pool located near Abidjan, has been identified by the State of Côte d'Ivoire as a potential resource for the production of drinking water.. The main objective of this project is to assess the quantitative and qualitative capacity of the Aghien lagoon to complement the water supply of Abidjan city in the near future. The main components of the project are: • to assess the water budget of the lagoon and its tributaries, • to characterize the spatial and temporal variability of contaminant levels and fluxes from the tributaries toward the lagoon, • to assess the sustainability of the water resources (quantity and quality) of the lagoon according to land use changes in the catchments . The project started in January 2015. The first year was devoted to the set-up of hydro-meteorological gauges within the lagoon watershed. Three major tributaries of the lagoon are considered, the Mé (4000 km2), the Djibi (78 km2) and Bete (206 km2) rivers. Since the start of the project, bi-monthly hydrochemical sampling surveys have been carried out along the tributaries and in the lagoon. The data available from the surveys concern the physico-chemical parameters, trace elements, all the forms of nitrogen and phosphorus, organic carbon, suspended solids. The Djibi and Bete watersheds are partly urbanized while the Mé basin is mainly rural. Baseflow has been identified as the major contribution to streamflow at the annual scale. The Mé flows into a channel downstream to the Aghien lagoon but during the floods, water from the Mé River can flow up the

Horizontal mobility of heavy metals in soil was performed by the Kruskal-Wallis test which was used to evaluate the heavy metals concentrations according to the upstream downstream disposition of soil sample sites. Then the Mann-Whitney test was applied to find if variances between upgradient and downgradient parameters concentrations in the soil sample sites were homogenous. The results show that the soil is rich in organic matter (organic carbon and organic nitrogen with a basic pH (7.94

Seven rapid diagnosis tests (RDTs) of HIV were evaluated by a panel group who collected serum samples from patients in Abidjan (HIV-1 = 203, HIV-2 = 25, HIV-dual = 25, HIV = 305). Kit performances were recorded after the reference techniques (enzyme-linked immunosorbent assay). The following RDTs showed a sensitivity of 100% and a specificity higher than 99%: Determine, Oraquick, SD Bioline, BCP, and Stat-Pak. These kits were used to establish infection screening strategies. The combination with 2 or 3 of these tests in series or parallel algorithms showed that series combinations with 2 tests (Oraquick and Bioline) and 3 tests (Determine, BCP, and Stat-Pak) gave the best performances (sensitivity, specificity, positive predictive value, and negative predictive value of 100%). However, the combination with 2 tests appeared to be more onerous than the combination with 3 tests. The combination with Determine, BCP, and Stat-Pak tests serving as a tiebreaker could be an alternative to the HIV/AIDS serological screening in Abidjan.

Otomycosis is a fungal infection, which leads to a damage of the external auditory meatus. The disease is worldwide in distribution but is said to be more common in tropical countries. Though otomycosis presumably occurs frequently in Africa, reports on its incidence and etiology are rare from Côte d'Ivoire. The objective of this study was to evaluate the prevalence of the disease and to identify aetiological agents as well as the risk factors. A cross-sectional study was carried out in the Otorhinolaryngology Department of the University Teaching Hospital of Yopougon from September 2007 to February 2008. For laboratory investigation, specimens were collected by means of a sterile swab. Samples were inoculated on Sabouraud's Dextrose Agar with and without antibiotics and incubated at 30°C for a period of 1 to 2 weeks. Identification was performed by direct microscopic examination on Cotton Blue Mount preparation and slide culture examination was used for differentiation of morphology. Biotyping was performed using Carbohydrate Fermentation tests, Carbohydrate Assimilation Tests (galerie Api 20 CAux TM - Sanofi Pasteur), Germ tube Test, detection of chlamydospore formation on corn meal agar. A total of 110 patients (sex-ratio=1.2) with suspected cases of otomycosis were investigated. Itching, otalgia, and hypoacusis were the symptoms reported by the patients and the apparent signs were debris in the ear, scabs and inflammation of the external auditory meatus. Of these, 88 cases (80%) were confirmed specifically of mycotic etiology on the basis of positive culture with 92 isolates consisting of yeasts (65.2%) and moulds (34.8%). The predominant etiological agents were Aspergillus flavus (28.4%), Candida guilliermondii (19.3%) and Candida parapsilosis (18.2%). The predisposing factors included previous otological pathology (P=0.010), frequent scratching of the external ear canal and use of ear drops (RR=3.47; IC 95%=1.3-9.27).

Full Text Available Cet article soutient la thèse selon laquelle l’apparition de la fraude douanière à Abidjan est générée par des opérateurs économiques véreux. Ce qui est à la base d’insécurité économique, politique et sociale au sein de jeune État comme la Côte D’Ivoire. Les douanes sont chargées d’appliquer du fait de leur présence aux frontières, de leur implication dans les opérations d’importation et d’exportation, de dédouanement, les normes techniques et les droits de protection intellectuelle. Les douanes gèrent les mouvements de fond et la législation des médicaments, etc. Elles assument des missions de surveillance qu’elles assurent sur l’ensemble du territoire (les marchandises dangereuses pour la santé, la sécurité ou la moralité publique, les marchandises contrefaites, les marchandises prohibées au titre d’engagements internationaux, les marchandises faisant l’objet de courants de fraude internationale. Certaines des marchandises dites sensibles relèvent de la catégorie des marchandises fortement taxées à l’entrée (article 7 désignées par arrêté du ministre de l’Économie et des Finances comme étant celles pour lesquelles l’ensemble des droits de douane, prélèvements et taxes diverses applicables à l’importation représente plus de 20 % de leur valeur, ou de la catégorie des marchandises prohibées (article 38. Ainsi cet article a pour objectif de décrire la fraude douanière telle qu’elle s’effectue présentement à Abidjan. Nous allons montrer le fait que les fraudeurs s’adaptent aux structures en place, il est donc intéressant de comprendre le modus operandi des fraudeurs et leurs stratégies d’adaptation. This article supports the argument that the appearance of customs fraud in Abidjan is generated by unethical traders. What is the basis of economic insecurity, and social policy in the young state like Côte d’Ivoire? Customs are responsible for enforcing the fact

The objective of this study was to examine induced abortion in Côte d'Ivoire. A nationwide cross-sectional descriptive study of induced abortion was carried out in 2007 among 3,057 women aged 15-49 years. The study showed that induced abortion is a widespread practice in Côte d'Ivoire, with a prevalence estimated at 42.5%. The women who had undergone an abortion were generally under 25, unmarried, and illiterate, and had used contraception. More than half (52.1%) of all induced abortions were performed at home by traditional abortionists or were self-induced with plants or decoctions. The main reasons for induced abortion were concern about the reaction of parents (27.7%), age (22.2%), a lack of financial resources (21.3%) and the desire of women to continue their education. More than half of the participants (55.8%) stated that they had suffered complications, which were more common after a home abortion than after a hospital abortion. Political and legal measures or reforms aimed at changing abortion laws in Côte d'Ivoire and better access to family planning are required in order to prevent or treat the social issue of induced abortion.

Groundwater is the largest global reserves of continental freshwater (Bosca, 2002) and also an important source of drinking water in many parts of the world (Brassington. 2007). However, this resource is today threatened by pollution such as inadequate supply of drinking water services, inaccessibility and / or dilapidated sanitation facilities and excessive use fertilizers, and industrial wastewater and solid waste pesticides (Boubacar, 2010) and the rapid urbanization in great cities (Foster, 2001). Abidjan, the largest city in Côte d'Ivoire is also facing pollution problems such as illegal dumping of waste, waste oil spilled garages, land application of domestic and industrial wastewater, automotive workshops, overexploitation of sand in the Ebrié lagoon, open waste dump of Akouédo and the spill of about 400,000 liters of toxic waste from the ship "Probo Koala" in August 2006. The Abidjan aquifer or the Continental terminal aquifer is the main source of supply drinking water. It is mainly composed of sandy and it is an unconfined aquifer as a whole (Jourda, 1987). According to Gilli and al., (2012), the recharge of unconfined aquifers comes mostly from the infiltration of surface water including rainwater. These waters on their transport in the basement could carry certain pollutants into groundwater. Kouamé (2007) reports a potential groundwater pollution of the "Continental terminal" aquifer in Abidjan. In addition to the cases cited pollution, there has been a proliferation of service stations in the district of Abidjan and this can cause possible pollution. We deemed it necessary to conduct a study on the groundwater pollution of Abidjan by oil in general. We chose benzene to simulate organic pollution in case of accident. To observe the likely evolution of such contaminants in the subsurface, we developed hydrogeological models that couple groundwater flow and benzene transport with FEFLOW software in steady and transient states. The models are composed

Labor Market Distortions in Côte d'Ivoire:

This paper investigates the extent and nature of distortions in the labor market in the Republic of Côte d'Ivoire by using quantile regression analysis on employer-employee data from the manufacturing sector. We found that the labor markets in Côte d'Ivoire do not seem to be much distorted. Unions...... may influence employment through tenure but do not seem to influence wages directly except for vulnerable minorities that seem protected by unions. Establishment-size wage effects are pronounced and highest for white-collar workers. This may be explained by the efficiency wage theory, so that, even...... in the absence of unions, segmentation and inefficiencies will still be present as long as firms seek to retain their employees by paying wages above the market clearing level. The inefficiency arising from establishment-size wage effects can be mitigated by education....

Full Text Available This work is part of the DACCIWA FP7 project (Dynamics-Aerosol-Chemistry-Cloud Interactions in West Africa in the framework of the Work Package 2 Air Pollution and Health. This study aims to characterize urban air pollution levels through the measurement of NO2, SO2, NH3, HNO3 and O3 in Abidjan, the economic capital of Côte d'Ivoire. Measurements of inorganic gaseous pollutants, i.e. NO2, SO2, NH3, HNO3 and O3 were performed in Abidjan during an intensive campaign within the dry season (15 December 2015 to 16 February 2016, using INDAAF (International Network to study Deposition and Atmospheric chemistry in AFrica passive samplers exposed in duplicate for 2-week periods. Twenty-one sites were selected in the district of Abidjan to be representative of various anthropogenic and natural sources of air pollution in the city. Results from this intensive campaign show that gas concentrations are strongly linked to surrounding pollution sources and show a high spatial variability. Also, NH3, NO2 and O3 gases were present at relatively higher concentrations at all the sites. NH3 average concentrations varied between 9.1 ± 1.7 ppb at a suburban site and 102.1 ± 9.1 ppb at a domestic fires site. NO2 mean concentration varied from 2.7 ± 0.1 ppb at a suburban site to 25.0 ± 1.7 ppb at an industrial site. Moreover, we measured the highest O3 concentration at the two coastal sites of Gonzagueville and Félix-Houphouët-Boigny International Airport located in the southeast of the city, with average concentrations of 19.1 ± 1.7 and 18.8 ± 3.0 ppb, respectively. The SO2 average concentration never exceeded 7.2 ± 1.2 ppb over all the sites, with 71.5 % of the sampling sites showing concentrations ranging between 0.4 and 1.9 ppb. The HNO3 average concentration ranged between 0.2 and 1.4 ppb. All these results were combined with meteorological parameters to provide the first mapping of gaseous pollutants

The objectives of our study were to analyse the prescriptions of antibiotics and assessing the relevance of pharmacist interventions (PI) in outpatient consultations in a pediatric unit of a Teaching Hospital of Abidjan, Côte d'Ivoire. We conducted a cross-sectional descriptive study from May to December 2013. The analysis of antibiotic prescriptions was documented. The tool of PI classification validated by the French Society of Clinical Pharmacy was used. The PI rating was made by prescribers. This rating evolved from PI0 to PI3 depending on the severity of the clinical impact of the problem and to the severity of clinical consequences avoided by the PI. The relevance was evaluated by the PI acceptance rate by physicians and clinical evaluation of their impact. Our study included 150 patients with a mean age of 11.75 months and a sex ratio (M/F) of 2. The amoxicillin-clavulanic acid (27.2 %) and amoxicillin (22.3 %) were the most prescribed antibiotics. Sixty-three drug-related problems (DRPs) were detected on the antibiotic prescriptions. They were non-optimal drug administration plan (88.9 %) and underdose (11.1 %). The amoxicillin-clavulanic acid (61.9 %) and josamycin (17.4 %) were the most affected by these DRPs. PI were related to the precision of modes of drug administration (88.9 %) and dose adjustments (11.1 %). The prescribers accepted 93.7 % of PIs. All accepted PIs was rated PI1 (significant clinical impact). PIs performed on antibiotic prescription were relevant with a high rate of acceptance and a significant clinical impact.

1988-01-01

The Second Workshop of Participants in the Joint FAO-IOC-WHO-IAEA-UNEP Project on Monitoring of Pollution in the Marine Environment of the West and Central African Region (WACAF/2) was attended by 29 participants from 10 countries (Senegal, The Gambia, Sierra Leone, Cote d'Ivoire, Ghana, Benin, Nigeria, Cameroun, Congo and Gabon). Levels of metals, chlorinated hydrocarbons and petroleum components in marine biota were discussed in seven scientific reports which were presented by the participating scientists (Cote d'Ivoire, Sierra Leone, Nigeria, The Gambia, ghana and Cameroun). Three of the presented reports were on organochlorines and four dealt with trace metal levels in marine organisms. The Representative of the International Atomic Energy Agency (IAEA) reviewed the results obtained during the data quality assurance intercalibration exercises carried out in the region during the first phase. The result received are still within acceptable range. However, there seems to be a trend for values to be higher than the range of finally certified concentrations. Considering that most results were clearly better in the second exercise, after equipment service, part of the earlier deviation might be attributed to instrument malfunctions. These results can be regarded as fairly encouraging for the future development in the West and Central African marine pollution monitoring programme. Refs, tabs

Full Text Available BackgroundWe conducted an experimental study to compare the effect of massage using topical agents (Kelo-cote or Contractubex on scar formation by massaging the healed burn wound on the dorsal area of Sprague-Dawley (SD rats.MethodsFour areas of second degree contact burn were made on the dorsal area of each of 15 SD rats, using a soldering iron 15 mm in diameter. After gross epithelialization in the defect, 15 SD rats were randomly divided into four groups: the Kelo-cote group, Contractubex group, Vaseline group, and control group. Rats in three of the groups (all but the Control group were massaged twice per day for 5 minutes each day, while those in the Control group were left unattended. For histologic analysis, we performed a biopsy and evaluated the thickness of scar tissue.ResultsIn the Kelo-cote and Contractubex groups, scar tissue thicknesses showed a significant decrease, compared with the Vaseline and control groups. However, no significant differences were observed between the Kelo-cote and Contractubex groups. In the Vaseline group, scar tissue thicknesses showed a significant decrease, compared with the control groups.ConclusionsThe findings of this study suggest that massage using a topical agent is helpful in the prevention of scar formation and that massage only with lubricant (no use of a topical agent also has a considerable effect, although not as much as the use of a topical agent. Thus, we recommend massage with a topical agent on the post-burn scar as an effective method for decreasing the scar thickness.

This study takes place in Abidjan, Côte d'Ivoire, inside a program of reduction of the mother-to-child HIV transmission, the Ditrame Plus study, ANRS 1201-1202. In this program, HIV test is proposed to women during antenatal consultations. After the test, we have followed during twelve months after childbirth 400 women who were HIV negative. We examine in this paper how these women who have been HIV tested during pregnancy and who are HIV seronegative communicate with their partner about HIV test and about the risk of HIV infection. We analyse also the behaviour of the partners in terms of HIV testing and condom use with their wife. Among the 400 women followed, for 6 upon 10, the HIV test allowed them to reinforced communication with their partner upon STD and AIDS. For 2 upon 10, the HIV test was the occasion to start a dialogue on this subject. On the whole, communication between spouses on these questions became more frequent after HIV test in all socio- demographic classes. They were more frequent when the husband was instructed and they were more easy in monogamous couples. Overall, the spouses discussed about the protection by condoms of the eventual extramarital sexual intercourse of the husband, in order to avoid the risk of infection of the HIV- wife. Ninety per cent of women asked their husband (or regular sexual partner) to use condoms if he would have sexual intercourse "outside". Women used different strategies to tackle this difficult subject of extramarital intercourse with their husband : they approached it as a simple discussion, or as a joke, or when they had a conjugal dispute. Ninety seven per cent of the followed women notified their partner they had been HIV tested. This notification was easy because they were seronegative. Then 94 % of these women told their partner he should be HIV tested also. But, despite this high figure, only a quarter of the partners asked an HIV test and were tested. Many of them were scared by a possible infection

To investigate cigarette smoking prevalence and exposure to various forms of cigarette marketing among students in 10 African countries. We used data collected during 2009-2011 from the Global Youth Tobacco Survey (GYTS), a school-based cross-sectional survey of students aged 13-15years, to measure the prevalence of cigarette smoking and exposure to cigarette marketing; comparisons to estimates from 2005 to 2006 were conducted for five countries where data were available. Current cigarette smoking ranged from 3.4% to 13.6% among students aged 13-15 in the 10 countries studied, although use of tobacco products other than cigarettes was more prevalent in all countries except in Cote D'Ivoire. Cigarette smoking was higher among boys than girls in seven out of the 10 countries. Among the five countries with two rounds of surveys, a significant decrease in cigarette smoking prevalence was observed in Mauritania and Niger; these two countries also experienced a decline in three measures of cigarette marketing exposure. It is also possible that smoking prevalence might have risen faster among girls than boys. Cigarette smoking among youth was noticeable in 10 African countries evaluated, with the prevalence over 10% in Cote D'Ivoire, Mauritania, and South Africa. Cigarette marketing exposure varied by the types of marketing; traditional venues such as TV, outdoor billboards, newspapers, and magazines were still prominent. Published by Elsevier Inc.

Full Text Available This paper examines the relationship between financial development, economic growth and energy consumption in Cote d’Ivoire over the period 1971-2011. To do so, the study first built a synthetic indicator of financial development through the principal component analysis technique (PCA and used four energy sources such as electric power consumption, electricity production from renewable sources, electricity production from oil sources and electricity production from hydroelectric sources. Then, employing the autoregressive distributed lag (ARDL bounds testing approach to cointegration, we find that there is a long run relationship between financial development, economic growth and energy consumption sources. Furthermore, the results of the vector error correction models (VECM reveal unidirectional causality running from financial development to energy consumption sources, bidirectional causality between economic growth and energy consumption and unidirectional causality from financial development to economic growth in the long run. The mixed results are due to the use of different proxies for energy consumption. Accordingly, this paper recommends that policy makers should solicit the support of financial sector in order to solve energy problems and further the diversification of the energy consumption sources since financial development has a positive effect on energy consumption in long run. Moreover, government should develop public-private partnership (PPP to stimulate economic growth, improve the access to energy and maintain a sustainable development in Cote d’Ivoire.

The aim of this study was to establish a national Early Awareness and Alert (EAA) system for the identification and assessment of new and emerging health technologies in Italy. In 2008, Agenas, a public body supporting Regions and the Ministry of Health (MoH) in health services research, started a project named COTE (Observatory of New and Emerging Health Technologies) with the ultimate aim of implementing a national EAA system. The COTE project involved all stakeholders (MoH, Regions, Industry, Universities, technical government bodies, and Scientific Societies), in defining the key characteristics and methods of the EAA system. Agreement with stakeholders was reached using three separate workshops. During the workshops, participants shared and agreed methods for identification of new and emerging health technologies, prioritization, and assessment. The structure of the Horizon Scanning (HS) reports was discussed and defined. The main channels for dissemination of outputs were identified as the EuroScan database, and the stakeholders' Web portals. During the final workshop, Agenas presented the first three HS reports produced at national level and proposed the establishment of a permanent national EAA system. The COTE Project created the basis for a permanent national EAA system in Italy. An infrastructure to enable the stakeholders network to grow was created, methods to submit new and emerging health technologies for possible evaluation were established, methods for assessment of the technologies selected were defined, and the stakeholders involvement was delineated (in the identification, assessment, and dissemination stages).

The probability of no increase in CD4 cells was 2.6 higher in patients with a baseline CD4 cell count of ≥200/mm3. At 12 months, CD4 cell response was significantly influenced by both baseline CD4 cell count and adherence. The probability of no increase in CD4 cells was three times higher in patients with a baseline CD4 cell count of ≥200/mm3 and 0.15 times lower with adherent patients. At 18 months, CD4 cell response was also significantly influenced by both baseline CD4 cell count and adherence. The probability of no increase in CD4 cells was 5.1 times higher in patients with a baseline CD4 cell count of ≥200/mm3 and 0.28 times lower with adherent patients. At 24 months, optimal CD4 cell response was significantly influenced by adherence alone. Adherence increased the probability (by 5.8 of an optimal increase in CD4 cells.

Epidemiological studies associate air pollution, especially particulate, increased morbidity and mortality from respiratory and cardiovascular origin . Africa, which has an urbanization rate among the highest in the world, is particularly exposed. The 'Initiative on the air quality in Sub-Saharan Africa' showed the importance of atmospheric concentrations of certain pollutants such as nitrogen oxides, sulfur dioxide and particulate matter (PM 10 ). Like the great capitals of Africa, Abidjan, economic capital and most industrialized city of Ivory Coast is facing an air pollution from industrial-urban and health consequences for its population of nearly 6 million inhabitants. To better understand the mechanisms of action resulting from pulmonary exposure to particulate atmospheric aerosols, we proposed: (i) to collect atmospheric particles (PM 2.5 ) using high volume cascade impaction in the District of Abidjan in three influences (rural, urban or industrial), (ii) to determine their main physicochemical, (iii) assess their cytotoxicity and their role in the induction of oxidative damage in a model of human lung cells (A549) in culture. The chemical composition of the atmospheric particles revealed their heterogeneity, and many inorganic (e.g. Al, Ca, Fe, Mn, Zn, Ni, Cr, Cu, Pb, Mg) and organic compounds (e.g. paraffins) were quantified at the three sites. Their effect concentrations (EC) to 10 and 50% on the A549 were as follows: influence rural: EC 10 = 5.91 μg/cm 2 and EC 50 29.55 μg/cm 2 , urban influence: EC 10 = 5 .45 μg/cm 2 and EC 50 = 27.23 μg/cm 2 , and industrial influence: EC 10 = 6.86 μg/cm 2 and EC 50 = 34.29 μg/cm 2 . Exposure of A549 cells to Abidjan city's PM samples for 24, 48 or 72 hours to their EC 10 or EC 50 induced oxidative damage, as demonstrated by the formation of malon-dialdehyde, changes in enzyme activity of superoxide dismutase and alteration of glutathione status.

The malnutrition of children under five years of age constitutes a major public health problem in most developing countries. A cross-section study was carried in 2003 in the northern part of Côte d'Ivoire to determine the prevalence of chronic malnutrition and to identify risk factors among children under five years of age living in urban and rural areas of the northern part of Côte d'Ivoire. A total of 292 and 268 children under five years of age residing respectively in urban and rural areas were included in the study. Their median age was 24 months. Chronic malnutrition was more frequent in children from rural areas (39.9%) than in those living in urban areas (16.7%). Malnutrition was significantly associated with the type of food consumed by children under two years of age in urban areas, and it was strongly linked to emaciation of the mother and presence of childhood fever in rural areas. In light of these results, we advocate a healthy diet and adequate health status for the mother and child to improve the nutritional status of children. Moreover, these results need to be completed and complemented by further studies for more detailed information to contribute to a better definition of actions to fight efficiently against malnutrition among children of the northern part of Côte d'Ivoire.

We report the first national programme in Côte d'Ivoire to evaluate the feasibility of nurse-led HIV care as a model of task-sharing with nurses to increase coverage and decentralisation of HIV services. Twenty-six public HIV facilities implemented either a nurse-with-onsite-physician or a nurse-with-visiting-physician model of HIV task-sharing. Routinely collected patient data were reviewed to analyse patient characteristics of those enrolling in care and initiating antiretroviral therapy (ART). Retention, loss to programme and death were compared across facility-level characteristics. A total of 1224 patients enrolled in HIV care, with 666 initiating ART, from January 2012 to May 2013 (median follow-up 13 months). The majority (94%) were adults ≥15 years. Fourteen facilities provided ART initiation for the first time during the pilot period; 20 facilities were primary level. Nurse-led care with a visiting physician was provided in 14 of the primary-level facilities. Nurse-led ART care with an onsite physician was provided in all secondary-level facilities and six of the primary-level facilities. During the pilot, 567 (85%) of patients were retained, 28 (4.2%) died, 47 (7.1%) were lost to follow-up, and 24 (3.6%) transferred. Five deaths (10.9%) were recorded among children as compared to 23 deaths (3.7%) among adults (P = 0.037). There were no differences in retention by model of nurse-led ART care. Task-sharing of HIV care and ART initiation with nurses in Côte d'Ivoire is feasible. This pilot illustrates two models of nurse-led HIV care and has informed national policy on nurse-led HIV care in Côte d'Ivoire. © 2017 John Wiley & Sons Ltd.

Governments in developing countries are continuously searching for new and improved tax bases. Existing methods of taxation in these countries frequently fall short of meeting acceptable criteria of efficiency, equity and administrative ease. This paper argues that there is a compelling fiscal rationale for encouraging greater reliance on taxing the consumption of electrical and telephone (ET) services. Greater emphasis on this selective commodity tax base would contribute to the achievement ...

The objective of this paper was to describe recent data from Burkina Faso and Côte d'Ivoire on Human African Trypanosomosis medical monitoring in order to (i) update the disease situation in these two countries that have been sharing important migratory, economic and epidemiological links for more than a century and (ii) to define the future strategic plans to achieve the goal of a sustainable control/elimination process. Results of active and passive surveillance indicate that all sleeping sickness patients diagnosed these last years in Burkina Faso were imported cases from Côte d'Ivoire. Nevertheless the re-introduction of the parasite is effective and the risk of a resumption of transmission exists. In Côte d'Ivoire, few cases are still diagnosed in several historical foci and the fear exists that the disease could reemerge in these foci or spread to other areas. In order to achieve a sustainable elimination of sleeping sickness in these two countries, control entities have to adapt their strategy to the different epidemiological contexts. At the exception of specific cases, the current disease prevalence no longer justifies the use of expensive medical surveys by exhaustive screening of the population. New disease control strategies, based on the exchange of epidemiological information between the two countries and integrated to the regular national health systems are required to target priority intervention areas. Follow-up in time of both treated patients and serological suspects that are potential asymptomatic carriers of parasite is also important. In parallel, researchers need to better characterize the respective roles of the human and animal reservoir in the maintenance of transmission and evaluate the different control strategies taken by National Control Programs in term of cost/effectiveness to help optimize them.

The EU-funded project DACCIWA (Dynamics-Aerosol-Chemistry-Cloud Interactions in West Africa) is investigating the relationship between weather, climate, air pollution and health in southern West Africa. The air over the coastal region of West Africa is a unique mixture of natural and anthropogenic gases, liquids and particles, emitted in an environment, in which multi-layer cloud decks frequently form. These exert a large influence on the local weather and climate, which has never been studied in detail over West Africa: this information is currently not included in the majority of weather and climate models. For the first time, the entire chain of impacts of natural and manmade emissions on the West African atmosphere was investigated in a coordinated field campaign. As part of this campaign, three research aircraft (Falcon 20, Twin Otter and ATR) based in Lomé (Togo) flew targeted 50 missions over West Africa from 27 June to 16 July 2016. In that campaign also, three highly instrumented measuring sites inland were set up with weather balloons launched several times a day across the region. The main objective was to build robust statistics of cloud properties in southern West Africa in different chemical landscapes (background state, ship/flaring emissions, polluted megacities, agricultural and forest areas, dust from the Sahel/Sahara). In addition, DACCIWA scientists working on measurements of urban emissions, air pollution, and health have set up four urban sites in Abidjan (Cote d'Ivoire) and Cotonou (Benin) focusing on main specific regional combustion sources (domestic fires, traffic and waste burning). Long-term measurements of gases and particles and census of hospital admissions for respiratory diseases were started in January 2015 and will continue until March 2017 to determine the links between human health and air pollution. Intensive measurement periods took place in July 2015, January 2016, and July 2016 (a final one is planned for January 2017) in

Full Text Available Le présent article rend compte des déterminants de la dynamique spatiale de Bingerville, une ville historique du sud de la Côte d’Ivoire. Les sources cartographiques émanant de missions aériennes ont permis de faire la synthèse de la dynamique spatiale. Une enquête auprès du service technique de la mairie a fourni les informations relatives à la gestion du foncier.L’étude révèle que de 1960, date de proclamation de l’indépendance, jusqu’en 1985, en dépit des interventions de l’Etat-providence, la croissance de la tache urbaine a été très peu significative. A la volonté de l’Etat de bâtir une ville moderne se sont opposées la méfiance et l’hostilité des autochtones, redoutant d’éventuelles expropriations.Avec les changements institutionnels survenus après 1985, qui ont vu l’apparition de nouveaux pouvoirs locaux décentralisés, la ville va connaître un regain de croissance. La communalisation, en mettant à l’ordre du jour l’implication des populations autochtones dans les mécanismes de création du sol urbain, est parvenue à relancer la dynamique des lotissements. Ainsi, sous l’impulsion d’opérateurs immobiliers privés, la ville a vu s’ajouter à son noyau initial de nouveaux quartiers ; elle connaît depuis lors un étirement en direction de ses périphéries ouest et nord et devient partie intégrante du front d’urbanisation oriental de la ville d’Abidjan.This article reports on the spatial dynamics of Bingerville, a historic city in southern Côte d'Ivoire.

Full Text Available The quality of the plant production in periurban agriculture is subjected to question given the potential contamination of soils that can affect the crops. The levels of contamination of soils and vegetables by Metallic trace elements (MTE as copper (Cu, zinc (Zn, cadmium (Cd and lead (Pb in the district of Abidjan, have been evaluated. Multi-sites survey of cropping areas of sweet potato and Hibiscus was conducted in three municipalities in Abidjan (Port-Bouët, Yopougon and Bingerville in relation to the intensity of industrial and commercial activities. The site of Bingerville has been used as the reference site referring to the low activities. Soil samples (in 0-20 cm and 20 - 40 cm, combined with that of plants (leaf, stem, and root, and water were collected, transported in laboratory for analysis. The total amounts of MTE in soil, as well as the different fractions extracted were determined in addition to the respective concentration in plants (Hibiscus and Sweet potato. Toxic level of Pb (< 8 mgkg-1 was observed in the plant organs collected at Port-Bouët site indifferently to crops while lowest content of Pb (35.5 mgkg-1 was accounting for the soil of Yopougon (39.8 mgkg-1. A neutral pH of the soil has been considered more favorable to the contamination of plants in Pb on the polluted sites somewhat differing for extractable fractions. The acidity and small width of leaf as observed for Hibiscus, were identified as the control factors of crop contamination in periurban agroecosystems prone to Pb pollution. To strengthen the consistency of the knowledge, studies of the interaction between Pb and Zn as well as the translocation of Pb in the plants to tubers are suggested in the tropical ecosystems.

In Ivory Coast, little is known about health needs and health access barriers among young people. The aim of this study was to describe health provision, health needs and barriers when seeking medical care, with an emphasis on sexual and reproductive health, and the acceptability of a medical examination for students attending their first year at the Houphouët-Boigny University, Abidjan, Ivory Coast. We conducted a representative cross-sectional study among second year students who were selected by two-stage equiprobable random sampling. In-depth interviews were conducted among students and the university health center staff. Five hundred and forty three students (322 men and 221 women) answered a questionnaire (participation rate 98.4%). Among women who ever had sex, 38.4% (95%CI [30.5%-47.0%]) had unmet contraception needs and 31.2% [23.7%-40.0%] had experienced an unwanted pregnancy. Fear about impaired fertility was the leading reason for non-use of hormonal contraception, the method of choice among most students. The main health problems among students, by order of frequency were malaria (54.3%), respiratory infection (44.6%), constipation (28.0%) and psychological problems (25.9%). High cost perception of services offered, despite their gratuity, were the main barriers against access to the university health center, indicating a lack of communication about this structure and its services. The majority of students favored the establishment of a medical examination during the first year at the university. Establishing a medical examination would improve health center visibility. The following services could be offered: (i) HIV, chlamydia and gonorrhea screening, (ii) hepatitis B virus screening and vaccination, (iii) provision and information about contraceptive methods, (iv) presentation of the university health center services. Dedicated spaces where students could have access to information about health-related topics (e.g. sexuality, nutrition, depression

The nutritional evaluation of the Bambara groundnut Ci12 landrace (Vigna subterranea (L.) Verdc.) seeds produced in Côte d'Ivoire shows a 19% content of protein, containing all the essential amino acids with tryptophan as the limiting amino acid, a total dietary fiber level of 10%, with a low soluble fraction content, and a fat content of 1.4%, with a high proportion of total unsaturated fatty acids (61%) of which 36% were n-6 fatty acids. This legume contains phosphorus, as the major mineral, followed by magnesium and calcium, and trace elements (iron, copper and zinc). It is characterized by the same amount of α-tocopherol and antioxidant capacity as common legumes. The high concentration of essential amino acids, n-6 fatty acids and minerals, mainly Fe, in the Ci12 landrace of Bambara groundnut indicates that this local legume has the potentiality to improve the nutritional status in Côte d'Ivoire and it could be regarded as a nutrient dense food.

Current vital statistics from governmental institutions in Côte d'Ivoire are incomplete. This problem is particularly notable for remote rural areas that have limited access to the health system. To record all deaths from 2009 to 2011 and to identify the leading causes of death in the Taabo health and demographic surveillance system (HDSS) in south-central Côte d'Ivoire. Deaths recorded in the first 3 years of operation of the Taabo HDSS were investigated by verbal autopsy (VA), using the InterVA-4 model. InterVA-4 is based on the World Health Organization 2012 VA tool in terms of input indicators and categories of causes of death. Overall, 948 deaths were recorded, of which 236 (24.9%) had incomplete VA data. Among the 712 deaths analyzed, communicable diseases represented the leading causes (58.9%), with most deaths attributed to malaria (n=129), acute respiratory tract infections (n=110), HIV/AIDS (n=80), and pulmonary tuberculosis (n=46). Non-communicable diseases accounted for 18.9% of the deaths and included mainly acute abdomen (n=38), unspecified cardiac diseases (n=15), and digestive neoplasms (n=13). Maternal and neonatal conditions accounted for 8.3% of deaths, primarily pneumonia (n=19) and birth asphyxia (n=16) in newborns. Among the 3.8% of deaths linked to trauma and injury, the main causes were assault (n=6), accidental drowning (n=4), contact with venomous plants/animals (n=4), and traffic-related accidents (n=4). No clear causes were determined in 10.0% of the analyzed deaths. Communicable diseases remain the predominant cause of death in rural Côte d'Ivoire. Based on these findings, measures are now being implemented in the Taabo HDSS. It will be interesting to monitor patterns of mortality and causes of death in the face of rapid demographic and epidemiological transitions in this part of West Africa.

Tchuenté, L A Tchuem; N'goran, E K

2009-11-01

Schistosomiasis and soil-transmitted helminthiasis occur throughout the developing world and remain a major public health problem in the poorest communities with enormous consequences for development. The extent of the problem has long been neglected because these diseases rarely kill at a young age and also because of their insidious nature. Today there exists a momentum and an unprecedented opportunity for a cost-effective control of these neglected tropical diseases. The control of these diseases has become a priority on the agenda of many governments, donors and international agencies. This paper highlights the progress made and future control activities in Cameroon and Côte d'Ivoire, where schistosomiasis and soil-transmitted helminthiasis control measures have been implemented over the past decade with limited budgets. In Cameroon, deworming activities were increased to encompass all ten regions in 2007 as a result of a co-ordinated effort of the Ministry of Health and the Ministry of Education with national and international partners. In Côte d'Ivoire, focal control activities were achieved with support from various partners. Prospects, opportunities and challenges for the control of neglected tropical diseases in these two countries are discussed.

Infectious meningitis accounts for enormous morbidity worldwide, but there is a paucity of data on its regional epidemiology in resource-constrained settings of sub-Saharan Africa. Here, we present a study on the aetiology of paediatric meningitis in central Côte d'Ivoire. Between June 2012 and December 2013, all cerebrospinal fluid (CSF) samples drawn at the University Teaching Hospital Bouaké were examined for the presence of bacterial and fungal pathogens. A causative agent was detected in 31 out of 833 CSF specimens (3.7%), with the most prevalent pathogens being Streptococcus pneumoniae (n=15) and Neisseria meningitidis (n=5). With the exception of neonates, these two bacteria were the most common agents in all age groups. Of note, only a single case of Haemophilus influenzae meningitis was detected. Hence, this study reports a considerable shift in the epidemiology of paediatric meningitis in central Côte d'Ivoire. Following the implementation of a nation-wide childhood vaccination programme against H. influenzae type b, this pathogen was much less frequently reported than in previous studies. The integration of specific vaccines against S. pneumoniae and N. meningitidis into the childhood vaccination programme in Côted'Ivoire holds promise to further reduce the burden due to infectious meningitis.

Poor wastewater management that results from a lack of appropriate sanitation infrastructure contributes to increasing health risks in urban areas in Côte d'Ivoire. We assessed the health risks associated with the use of wastewater for watering salad destined for human consumption, to help local authorities in developing appropriate risk mitigation measures for Yamoussoukro, the political capital of Côte d'Ivoire. We applied a stochastic approach based on quantitative microbiological risk assessment (QMRA), focusing on wastewater for farming activities and salad consumption at the household level. Farming activities rely on a large degree on contaminated water and are conducted without any protection. The QMRA highlights that the poor quality of watering water increased the microbiological risk of the two assessed groups of urban farmers and individual households. The annual risk of infection due to watering wastewater in the city is estimated at 0.01 per person per year (pppy) for Giardia lamblia and 0.2 pppy for Escherichia coli O157:H7. The annual risk from salad consumption is 0.01 pppy for G. lamblia and 0.9 pppy for E. coli O157:H7. Both the annual risks from farming activities and salad consumption were higher than the tolerable standard of risk of 10 -4 pppy as defined by the World Health Organization. There is a need to conduct a risk analysis and a cost-effectiveness study on intervention to improve public health and the livelihoods of the producers which are women in majority in Yamoussoukro.

Côte d'Ivoire is an endemic country for yellow fever, but no case was officially notified in recent years. In July 1999, however, one fatal case was reported. A German citizen was infected in the national park of Comoe, in the north eastern area of the country. In order to evaluate the extent of amaril virus circulation and the risk for local people, a virological, entomological and epidemiological investigation was carried out by the ministry of health, the OCCGE, the Côte d'Ivoire Pasteur Institute (IPCI) and the World Health Organisation in the area where the fatal case had been staying. 18 suspected and 24 confirmed mosquito catchers were identified by interview and a blood specimen was collected from each of them. In addition, 159 batches of mosquitoes from which 94 batches of potential vectors were collected; among the suspected cases, 22% were immunised against yellow fever. Serological and virological analyses were made at IPCI and the Paris Pasteur Institute by ELISA technique and isolation on cells cultures and newborn mice. All the suspicious sera and 87.5% of the catchers were positive for IgG anti-amaril virus. One catcher's serum was positive for IgM anti-amaril virus. 11 suspected sera were positive for IgG anti-dengue virus with 1 positive for IgM. 1 strain of amaril virus and 3 strains of Zika virus were isolated from mosquitoes at IPCI and confirmed by CRORA in Dakar. These results indicated that there is a yellow fever and dengue virus are prevalent among the human and vector populations in the study area. Preventive measures must be adopted to protect human beings at risk for amaril infection.

The Le Dantec serogroup of rhabdoviruses comprises Le Dantec virus from a human with encephalitis and Keuriliba virus from rodents, each isolated in Senegal. The Kern Canyon serogroup comprises a loosely connected set of rhabdoviruses many of which have been isolated from bats, including Kern Canyon virus from California, Nkolbisson virus from Cameroon, Central African Republic, and Cote d'Ivoire, Kolente virus from Guinea, Mount Elgon bat and Fikirini viruses from Kenya, and Oita virus from Japan. Fukuoka virus isolated from mosquitoes, midges, and cattle in Japan, Barur virus from a rodent in India and Nishimuro virus from pigs in Japan have also been linked genetically or serologically to this group. Here, we analyze the genome sequences and phylogenetic relationships of this set of viruses. We show that they form three subgroups within a monophyletic group, which we propose should constitute the new genus Ledantevirus. PMID:25487727

Ebola Virus Disease (EVD) is a disease caused by a virus of the genus Ebolavirus (EBOV), family Filoviridae. Ebola virus is classifed into five types, namely Zaire ebolavirus (ZEBOV), Sudan ebolavirus (SEBOV), Bundibugyo ebolavirus (BEBOV), Tai Forest ebolavirus also known as Cote d'Ivoire ebolavirus (CIEBOV), and Reston ebolavirus (REBOV). Identification of kinship types of Ebola virus can be performed using phylogenetic trees. In this study, the phylogenetic tree constructed by UPGMA method in which there are Multiple Alignment using Progressive Method. The results concluded that the phylogenetic tree formation kinship ebola virus types that kind of Tai Forest ebolavirus close to Bundibugyo ebolavirus but the layout state ebola epidemic spread far apart. The genetic distance for this type of Bundibugyo ebolavirus with Tai Forest ebolavirus is 0.3725.

Northern Côte d'Ivoire is the main livestock breeding zone and has the highest livestock cross-border movements in Côte d'Ivoire. The aim of this study was to provide updated epidemiological data on three neglected zoonotic diseases, namely brucellosis, Q Fever and Rift Valley Fever (RVF). We conducted three-stage cross-sectional cluster surveys in livestock and humans between 2012 and 2014 in a random selection of 63 villages and a sample of 633 cattle, 622 small ruminants and 88 people. We administered questionnaires to capture risk factors and performed serological tests including the Rose Bengal Plate Test (RBPT), Brucella spp. indirect and competitive ELISAs, Coxiella burnetii indirect ELISA and RVF competitive ELISA. The human seroprevalence for Brucella spp. was 5.3%. RBPT-positive small ruminants tested negative by the indirect ELISA. The seroprevalence of Brucella spp. in cattle adjusted for clustering was 4.6%. Cattle aged 5-8 years had higher odds of seropositivity (OR=3.5) than those aged ≤4years. The seropositivity in cattle was associated with having joint hygromas (OR=9), sharing the pastures with small ruminants (OR=5.8) and contact with pastoralist herds (OR=11.3). The seroprevalence of Q Fever was 13.9% in cattle, 9.4% in sheep and 12.4% in goats. The seroprevalence of RVF was 3.9% in cattle, 2.4% in sheep and 0% in goats. Seropositive ewes had greater odds (OR=4.7) of abortion than seronegative ones. In cattle, a shorter distance between the night pens and nearest permanent water bodies was a protective factor (OR=0.1). The study showed that the exposure to the three zoonoses is rather low in northern Côte d'Ivoire. Within a One Health approach, cost-benefit and cost-effectiveness of control measures should be assessed for an integrated control. Copyright © 2017 Elsevier B.V. All rights reserved.

Full Text Available Fish is one of the main sources of animal protein commercialized fresh or processed in Côte d’Ivoire. Health problems and even nutritional risks were noticed in spite of the existence of self-control systems and official controls in place. The objective of this study is to determine the causes of the sanitary insecurity and to evaluate the microbiological quality of the fish sold in the distribution channels of Abidjan. The Ishikawa method was used to identify the causes of health insecurity. The results of the microbiological analyzes carried out on frozen fish (Trachurus trachurus, Scombers combrus and fresh (Chrysichthys nigrodigitafus show that the coliform count is high (7.1 102 and 8.1 101 in fresh fish. However, Staphylococcus aureusis was below 10 CFU/g of product. Salmonella spp was absent in all the samples under the investigation. Labor remains the major source of germs and the most important “weakest link”. Appropriate corrective action will reduce the sanitary insecurity of fishsold in the distribution system by around 90%.

2017-02-01

Understanding and predicting outbreaks of contagious diseases are crucial to the development of society and public health, especially for underdeveloped countries. However, challenging problems are encountered because of complex epidemic spreading dynamics influenced by spatial structure and human dynamics (including both human mobility and human interaction intensity). We propose a systematical model to depict nationwide epidemic spreading in Côte d'Ivoire, which integrates multiple factors, such as human mobility, human interaction intensity, and demographic features. We provide insights to aid in modeling and predicting the epidemic spreading process by data-driven simulation and theoretical analysis, which is otherwise beyond the scope of local evaluation and geometrical views. We show that the requirement that the average local basic reproductive number to be greater than unity is not necessary for outbreaks of epidemics. The observed spreading phenomenon can be roughly explained as a heterogeneous diffusion-reaction process by redefining mobility distance according to the human mobility volume between nodes, which is beyond the geometrical viewpoint. However, the heterogeneity of human dynamics still poses challenges to precise prediction.

More than 1 billion people are currently infected with soil-transmitted helminths and schistosomes. The global strategy to control helminthiases is the regular administration of anthelmintic drugs to at-risk populations. However, rapid re-infection occurs in areas where hygiene, access to clean water, and sanitation are inadequate. In July 2011, inhabitants from two villages and seven hamlets of the Taabo health demographic surveillance system in south-central Côte d'Ivoire provided stool and urine samples. Kato-Katz and ether-concentration methods were used for the diagnosis of Schistosoma mansoni, soil-transmitted helminths (Ascaris lumbricoides, Trichuris trichiura, and hookworm), and intestinal protozoa. Urine samples were subjected to a filtration method for the diagnosis of Schistosoma haematobium. A questionnaire was administered to households to obtain information on knowledge, attitude, practice, and beliefs in relation to hygiene, sanitation, and defecation behavior. Logistic regression models were employed to assess for associations between questionnaire data and parasitic infections. A total of 1,894 participants had complete data records. Parasitological examinations revealed prevalences of hookworm, S. haematobium, T. trichiura, S. mansoni, and A. lumbricoides of 33.5%, 7.0%, 1.6%, 1.3% and 0.8%, respectively. Giardia intestinalis and Entamoeba histolytica/E. dispar were detected in 15.0% and 14.4% of the participants, respectively. Only one out of five households reported the presence of a latrine, and hence, open defecation was common. Logistic regression analysis revealed that age, sex, socioeconomic status, hygiene, and defecation behavior are determinants for helminths and intestinal protozoa infections. We found that inadequate sanitation and hygiene behavior are associated with soil-transmitted helminths and intestinal protozoa infections in the Taabo area of south-central Côte d'Ivoire. Our data will serve as a benchmark to monitor the

Pratiques agricoles des migrants burkinabè en Côte d'Ivoire et investissements socio-économiques liés à la culture du cacao

Full Text Available Agricultural Practices of Burkinabe Migrants in Côte d'Ivoire and Socio-economic Investments Related to the Cultivation of Cocoa. The political-military crisis that Côte d'Ivoire went through from 2000 to 2011 marked the neighboring countries, including Burkina Faso. Indeed, first State providing migrants to Ivory Coast, it faced many difficulties during this period, due to the high concentration of the Burkinabe community that resides there but also due to the commercial exchanges that exist between the two countries. The Ivorian agricultural sector is the domain of choice for many Burkina Faso citizens. We have highlighted in this research the agricultural activities and socio-economic investments related to the cocoa plantations of these migrants. Significant financial exchanges take place annually between the two countries, Burkina Faso being the main beneficiary. The most important financial transfers come from cocoa plantation which is the first export product of the Ivory Coast. It appears that remittances by Burkinabe migrants working in Ivorian plantations are mainly directed towards meeting the food needs of their families and investment in the real estate sector in Burkina Faso. A part of these transfers is absorbed by the impulses of solidarity of planters with their relatives. Thus, the emigrants establish and maintain relations with the family that has remained in the home country.

2012-12-01

The human sleep-wake cycle is characterized by significant individual differences. Those differences in the sleep-wake cycle are partially heritable but are also influenced by environmental factors like the light/dark cycle or social habits. In this study we analyse for the first time the sleep-wake rhythm of adolescent pupils and working adolescents in a less industrialised country in West Africa near the equator. The aim of this study was to explore the sleep wake cycle in this geographical region, using Côte d'Ivoire as an example. Data collection took place between 2nd of March and 10th of June 2009. 588 adolescents (338 girls, 250 boys) between 10 and 15 years (mean ± SD: 12.72 ± 1.63) participated in this study. We collected data on the religion of the participants (Christian (N = 159), Muslim (N = 352), other/no religion (N = 77)) and their occupation. Participants were either pupils attending school (N = 336) or adolescents that were already working (N = 252) and not attending school. The interviewer filled in the questionnaire. We found significant effects of age (p gender (p religion (p < 0.001) and region (p < 0.001). The midpoint of sleep was on average 1:26 (SD: 00:30) on weekdays and 1:37 (SD: 00:42) on weekend days. There are significant differences between weekdays and weekend days, but these were only small. Sleep duration suggests that adolescents in Côte d'Ivoire may gain sufficient sleep during week and weekend days, and thus, may live more in accordance with their own biological clock than adolescents in the northern hemisphere. In contrast, the data can be interpreted that adolescents live in a permanent 'jetlag'. Factors may be the more continuous light/dark cycle in the tropics, low amount of ambient light and less electricity.

Failure in detecting naturally occurring breeding sites of Aedes mosquitoes can bias the conclusions drawn from field studies, and hence, negatively affect intervention outcomes. We characterized the habitats of immature Aedes mosquitoes and explored species dynamics along a rural-to-urban gradient in a West Africa setting where yellow fever and dengue co-exist. Between January 2013 and October 2014, we collected immature Aedes mosquitoes in water containers in rural, suburban, and urban areas of south-eastern Côte d'Ivoire, using standardized sampling procedures. Immature mosquitoes were reared in the laboratory and adult specimens identified at species level. We collected 6,159, 14,347, and 22,974 Aedes mosquitoes belonging to 17, 8, and 3 different species in rural, suburban, and urban environments, respectively. Ae. aegypti was the predominant species throughout, with a particularly high abundance in urban areas (99.374%). Eleven Aedes larval species not previously sampled in similar settings of Côte d'Ivoire were identified: Ae. albopictus, Ae. angustus, Ae. apicoargenteus, Ae. argenteopunctatus, Ae. haworthi, Ae. lilii, Ae. longipalpis, Ae. opok, Ae. palpalis, Ae. stokesi, and Ae. unilineatus. Aedes breeding site positivity was associated with study area, container type, shade, detritus, water turbidity, geographic location, season, and the presence of predators. We found proportionally more positive breeding sites in urban (2,136/3,374, 63.3%), compared to suburban (1,428/3,069, 46.5%) and rural areas (738/2,423, 30.5%). In the urban setting, the predominant breeding sites were industrial containers (e.g., tires and discarded containers). In suburban areas, containers made of traditional materials (e.g., clay pots) were most frequently encountered. In rural areas, natural containers (e.g., tree holes and bamboos) were common and represented 22.1% (163/738) of all Aedes-positive containers, hosting 18.7% of the Aedes fauna.

Tracing health system challenges in post-conflict Côte d'Ivoire from 1893 to 2013.

Science.gov (United States)

Gaber, Sabrina; Patel, Preeti

2013-07-01

While scholarship on health in conflict-affected countries is growing, there has been relatively little analysis of how armed conflict affects health systems in specific African countries, especially former French colonies. There is even less literature on the role of history in shaping health systems and how historical factors such as inequity may influence health impacts of armed conflict. Based on Côte d'Ivoire, this article argues that historical multidisciplinary analysis can provide valuable insight into the macro-level political, economic and social determinants of the health system over time. It explores how armed conflict has affected health services and exacerbates historically inherited challenges to the health system including unequal distribution of health services, bias towards curative care in urban areas, inadequate human resources and weak health governance. In the post-conflict period, this understanding may assist governments and other stakeholders to develop more appropriate health policies that address both urgent and long-term health needs.

The 2014-2015 epidemic of Ebola virus disease in West Africa primarily affected Guinea, Liberia, and Sierra Leone. Several countries, including Mali, Nigeria, and Senegal, experienced Ebola importations. Realizing the importance of a trained field epidemiology workforce in neighboring countries to respond to Ebola importations, the Centers for Disease Control and Prevention Field Epidemiology Training Program unit implemented the Surveillance Training for Ebola Preparedness (STEP) initiative. STEP was a mentored, competency-based initiative to rapidly build up surveillance capacity along the borders of the at-risk neighboring countries Côte d'Ivoire, Mali, Senegal, and Guinea-Bissau. The target audience was district surveillance officers. STEP was delivered to 185 participants from 72 health units (districts or regions). Timeliness of reporting and the quality of surveillance analyses improved 3 months after training. STEP demonstrated that mentored, competency-based training, where learners attain competencies while delivering essential public health services, can be successfully implemented in an emergency response setting.

Yersinia enterocolitica, a Neglected Cause of Human Enteric Infections in Côte d’Ivoire

Background Enteropathogenic Yersinia circulate in the pig reservoir and are the third bacterial cause of human gastrointestinal infections in Europe. In West Africa, reports of human yersiniosis are rare. This study was conducted to determine whether pathogenic Yersinia are circulating in pig farms and are responsible for human infections in the Abidjan District. Methodology/Principal findings From June 2012 to December 2013, pig feces were collected monthly in 41 swine farms of the Abidjan district. Of the 781 samples collected, 19 Yersinia strains were isolated in 3 farms: 7 non-pathogenic Yersinia intermedia and 12 pathogenic Yersinia enterocolitica bioserotype 4/O:3. Farm animals other than pigs and wild animals were not found infected. Furthermore, 2 Y. enterocolitica 4/O:3 strains were isolated from 426 fecal samples of patients with digestive disorders. All 14 Y. enterocolitica strains shared the same PFGE and MLVA profile, indicating their close genetic relationship. However, while 6 of them displayed the usual phage type VIII, the other 8 had the highly infrequent phage type XI. Whole genome sequencing and SNP analysis of individual colonies revealed that phage type XI strains had unusually high rates of mutations. These strains displayed a hypermutator phenotype that was attributable to a large deletion in the mutS gene involved in DNA mismatch repair. Conclusions/Significance This study demonstrates that pathogenic Y. enterocolitica circulate in the pig reservoir in Côte d'Ivoire and cause human infections with a prevalence comparable to that of many developed countries. The paucity of reports of yersiniosis in West Africa is most likely attributable to a lack of active detection rather than to an absence of the microorganism. The identification of hypermutator strains in pigs and humans is of concern as these strains can rapidly acquire selective advantages that may increase their fitness, pathogenicity or resistance to commonly used treatments.

We present a preliminary report on the differences and similarities in material culture among four neighbouring chimpanzee (Pan troglodytes verus) communities. One of these communities includes Bossou, a long-term field site of wild chimpanzees, in Guinea, West Africa. We also conducted surveys of three new sites. Two of those surveyed areas, Seringbara in Guinea and Yealé in Côte d'Ivoire, are located less than 12 km away from Bossou in the Nimba Mountains region, which forms a natural boundary between Guinea and Côte d'Ivoire. The third, Diécké, is situated further south-west, closer to the border with Liberia. During the surveys, we gathered behavioural information about these neighbouring populations of chimpanzees. The differences, as well as similarities, in material culture were tabulated based on our findings. The three behavioural variants found so far involve differences in nut cracking behaviour with regard to the species of nut cracked. Some variation in materials used for nut cracking has also been recorded. However, we still need to establish whether these local variations can be explained by the demands of the physical and biotic environments in which the populations of chimpanzees live. If these alternative hypotheses can be excluded with continuing research at the study sites, these differences are likely to be cultural behaviours that are influenced by the social context and mode, i.e. horizontal, vertical or oblique, of transmission, by the social structure and organisation of each community and/or perhaps by some form of social norms prevalent within these communities.

Recently we have recorded some progress against the transmission of poliovirus in the African Region. This is attributable to a number of factors, including commitment of global partnerships against polio, improvement of existing strategies as well as a number of innovations in response to the disease in the Region. The WHO Regional Office in Africa documented these practices that led to the noticeable progress in the polio eradication initiative in the African Region, as lessons learnt and as part of polio legacy planning. The documentation exercise covered eight countries, namely Angola, Chad, Cote d'Ivoire, Democratic Republic of Congo, Ethiopia, Nigeria, Tanzania and Togo. A number of practices were identified. Some of these practices cut across countries while others were peculiar to specific countries. We have thus developed some manuscripts to capture these practices for publication in scientific journal so as to place them in the public domain for use. It is hoped that these practices will be deployed to other public health programmes in the Region and beyond. Copyright © 2016 The Author(s). Published by Elsevier Ltd.. All rights reserved.

Cholera burden in Africa remains unknown, often because of weak national surveillance systems. We analyzed data from the African Cholera Surveillance Network (www.africhol.org). During June 2011-December 2013, we conducted enhanced surveillance in seven zones and four outbreak sites in Togo, the Democratic Republic of Congo (DRC), Guinea, Uganda, Mozambique and Cote d'Ivoire. All health facilities treating cholera cases were included. Cholera incidences were calculated using culture-confirmed cholera cases and culture-confirmed cholera cases corrected for lack of culture testing usually due to overwhelmed health systems and imperfect test sensitivity. Of 13,377 reported suspected cases, 34% occurred in Conakry, Guinea, 47% in Goma, DRC, and 19% in the remaining sites. From 0-40% of suspected cases were aged under five years and from 0.3-86% had rice water stools. Within surveillance zones, 0-37% of suspected cases had confirmed cholera compared to 27-38% during outbreaks. Annual confirmed incidence per 10,000 population was cholera incidence, age distribution, clinical presentation, culture confirmation, and testing frequency. These results can help guide preventive activities, including vaccine use.

Gockowski, Jim; Sonwa, Denis

2011-08-01

The Guinean rain forest (GRF) of West Africa, identified over 20 years ago as a global biodiversity hotspot, had reduced to 113,000 km2 at the start of the new millennium which was 18% of its original area. The principal driver of this environmental change has been the expansion of extensive smallholder agriculture. From 1988 to 2007, the area harvested in the GRF by smallholders of cocoa, cassava, and oil palm increased by 68,000 km2. Field results suggest a high potential for significantly increasing crop yields through increased application of seed-fertilizer technologies. Analyzing land-use change scenarios, it was estimated that had intensified cocoa technology, already developed in the 1960s, been pursued in Cote d'Ivoire, Ghana, Nigeria and Cameroon that over 21,000 km2 of deforestation and forest degradation could have been avoided along with the emission of nearly 1.4 billion t of CO2. Addressing the low productivity of agriculture in the GRF should be one of the principal objectives of REDD climate mitigation programs.

Vaginal microbicides: how do you kick-start a global market?

Science.gov (United States)

1996-10-01

Efforts are underway to develop vaginal microbicides capable of protecting women against HIV and sexually transmitted disease. It was reported at the recent Vancouver international AIDS conference that 20 such products are in the preclinical stage, 13 in the early clinical stage, and two at the late clinical stage. The private sector, however, is not convinced of the commercial viability of vaginal microbicides, especially in developing countries. Johnson & Johnson has estimated there to be a US$40 million world market for vaginal microbicides, too small to garner the interest and involvement of the major research and development-based multinational pharmaceutical companies. The European Commission has therefore contracted Hillmark, a UK consultancy, to assess the market for such products in Cote d'Ivoire, Egypt, Kenya, South Africa, France, Poland, India, Thailand, Philippines, Brazil, and Venezuela. Corporate interest may be sparked by a convincing assessment of a higher market potential. Also at the Vancouver conference, the US Secretary of Health announced grant funding of US$100 million for research into microbicides.

Aedes mosquito-transmitted outbreaks of dengue and yellow fever have been reported from rural and urban parts of Côte d'Ivoire. The present study aimed at assessing Aedes spp. oviposition ecology in variously urbanized settings within arbovirus foci in southeastern Côte d'Ivoire. Aedes spp. eggs were sampled using a standard ovitrap method from January 2013 to April 2014 in different ecosystems of rural, suburban and urban areas. Emerged larvae were reared until the adult stage for species identification. Aedes spp. oviposition ecology significantly varied from rural-to-urban areas and according to the ecozones and the seasons. Species richness of Aedes spp. gradually decreased from rural (eight species) to suburban (three species) and urban (one species) areas. Conversely, emerged adult Aedes spp. mean numbers were higher in the urban (1.97 Aedes/ovitrap/week), followed by the suburban (1.44 Aedes/ovitrap/week) and rural (0.89 Aedes/ovitrap/week) areas. Aedes aegypti was the only species in the urban setting (100 %), and was also the predominant species in suburban (85.5 %) and rural (63.3 %) areas. The highest Ae. aegypti mean number was observed in the urban (1.97 Ae. aegypti/ovitrap/week), followed by the suburban (1.20 Ae. aegypti/ovitrap/week) and rural (0.57 Ae. aegypti/ovitrap/week) areas. Aedes africanus (9.4 %), Ae. dendrophilus (8.0 %), Ae. metallicus (1.3 %) in the rural, and Ae. vittatus (6.5 %) and Ae. metallicus (1.2 %) in the suburban areas each represented more than 1 % of the total Aedes fauna. In all areas, Aedes species richness and abundance were higher in the peridomestic zones and during the rainy season, with stronger variations in species richness in the rural and in abundance in the urban areas. Besides, the highest Culex quinquefasciatus abundance was found in the urban areas, while Eretmapodites chrysogaster was restricted to the rural areas. Urbanization correlates with a substantially higher abundance in Aedes mosquitoes and

A cross-sectional descriptive study was conducted from medical data of inpatients with tetanus in the Department of Infectious and Tropical Diseases of the University Hospital of Treichville in Abidjan from January 2003 to December 2007. In five years, 221 cases of tetanus have been hospitalized. The tetanus gateway was found in 188 patients (85%). Tetanus gateway linked to care was found in 22 patients (11.7%). Acts of care in question were intramuscular injections (10 cases) and operative procedures (12 cases). Concerning medical care by intramuscular injection, quinine (four cases), sulfadoxine-pyrimethamine (one case), and long-acting penicillin (one case) were the identified drugs. The operative procedures mainly involved were skin sutures (nine cases), cures of hernia (two cases), and flattening of Fournier's gangrene (one case). The average incubation period was 9.5 days. The invasion lasted for an average of 1.8 days. On admission, tetanus was immediately generalized for all patients with the presence of paroxysms in 20 patients (90.9%). The lethality of tetanus related care was 54.5%. The death rate in the first 48 hours of hospitalization was estimated at 83.3%. The average length of hospital stay was 14.6 days. Health workers should be involved in the prevention of tetanus in improving the quality of care and especially in reducing intramuscular injections. Also, any patient not immunized against tetanus should receive anti-tetanus serum and an update of its tetanus vaccine before any invasive procedures.

Schistosomiasis and soil-transmitted helminthiasis are two high-burden neglected tropical diseases. In highly endemic areas, control efforts emphasize preventive chemotherapy. However, as morbidity, infection, and transmission begin to decrease, more targeted treatment is likely to become more cost-effective, provided that comparatively cheap diagnostic methods with reasonable accuracy are available. Adults were administered an anamnestic questionnaire in mid-2010 during a cross-sectional epidemiological survey in the Taabo health demographic surveillance system in south-central Côte d'Ivoire. Questions pertaining to risk factors and signs and symptoms for schistosomiasis and soil-transmitted helminthiasis were included. The individuals' helminth infection status and their belonging to three different anthelmintic treatment groups were compared with the questionnaire results (i) to inform the local health authorities about the epidemiological and clinical footprint of locally prevailing helminthiases, and (ii) to explore the scope and limits of an anamnestic questionnaire as monitoring tool, which eventually could help guiding the control of neglected tropical diseases in control-induced low-endemicity settings. Our study sample consisted of 195 adults (101 males, 94 females). We found prevalences of hookworm, Trichuris trichiura, Schistosoma haematobium, and Schistosoma mansoni of 39.0%, 2.7%, 2.1%, and 2.1%, respectively. No Ascaris lumbricoides infection was found. Helminth infection intensities were generally very low. Seven, 74 and 79 participants belonged to three different treatment groups. Multivariable logistic regression models revealed statistically significant (p<0.05) associations between some risk factors, signs, and symptoms, and the different helminth infections and treatment groups. However, the risk factors, signs, and symptoms showed weak diagnostic properties. The generally low prevalence and intensity of helminth infection in this part of

Changing tracks as situations change: humanitarian and health response along the Liberia-Côte d'Ivoire border.

In recent years, protracted crises and fragile post-conflict settings have challenged the co-existence, and even the linear continuum, of relief and development aid. Forced migration has tested humanitarian and development paradigms where sudden-onset emergencies, violence and displacement arise alongside ongoing development work. Drawing on Médecins Sans Frontières interventions in the region from December 2010 to May 2011, this paper examines aid and healthcare responses to displacement in Côte d'Ivoire and Liberia; it focuses on challenges to the maintenance of preparedness for such foreseeable emergencies and to adaptation in response to changing situations of displacement and insecurity. This 'backsliding' from development to emergency remains a substantial challenge to aid; yet, in exactly such cases, it also presents the opportunity to ensure access to medical care that is much more urgently needed in times of crisis, including the suspension of user fees for medical care. © 2014 The Author(s).

Impact of the decommissioning of nuclear facilities and radioactive waste trafficking in Africa

International Nuclear Information System (INIS)

Abukabar, B. G.

2007-01-01

Africa is the world's second largest and the most populated continent after Asia, it has a total population of approximately 800 million people. It comprises of 54 sovereign nations out of which 36 are coastal countries and blessed with over 100 Seaports. Apart from Nigeria, South Africa, Egypt, Libya, Morocco, Tunisia and Libya, all the other remaining African countries are extremely poor and unviable. As a result of this, Africa has been experiencing a lot of civil unrest since the 1960s when most of the African countries gained their independence from their former colonial masters, the civil unrest in countries like Angola, Democratic Republic of Congo, Sudan, Burundi, Rwanda, Mozambique, Liberia, Sierra Leon and recently in Cote D'Ivoire, are good examples. In addition to abject poverty of less than 1$ per person per day makes trafficking in drugs, arms, humans and weaponry trade on the continent becomes much more rampant. Today the continent is experiencing the coming of a new evil deal called 'Trade in radioactive waste'; which involves the transporting of materials from existing or decommissioned nuclear plants ranging from fairly used Trucks, laboratory equipment s, office facilities, clothing materials like booths and raincoats, roofing sheets and even toxic waste from the developed countries to it's waste bin in Africa, where it is unsafely disposed after collecting millions of dollars from It's original owners (UN report, 2001). Recent statistics have revealed that most of the people involved in the evil businesses of trafficking in drugs, human, arms and trading in weaponry, are diverting in to the so called new evil business of 'Trade in Radioactive waste' because this new evil business financially exceeds the rest of the above listed evil businesses. This is clearly proved by the recent toxic waste disposed in Abidjan Cot Devoir in August 2006. The materials from the decommissioned nuclear plant sites can be hazardous if for example a roofing sheet

In Côte d'Ivoire, HIV testing and counselling has been identified as a priority in the National 2006-2010 AIDS Strategic Plan, which is designed to evaluate the prevalence of HIV in rural areas measured by means of a mobile strategy. We conducted a cross-sectional descriptive and analytical study from 1st April, 2007 to 31st March 2008 in six rural areas of Côte d'Ivoire: Dabou, San Pedro, Abengourou, Tanda, Daloa, and Soubré*. The study population consisted of subjects attending the mobile voluntary counselling and testing units. The mean prevalence of HIV infection in this study was 5.30%. The mean prevalence rate in men was 5.26%, with a peak of 7.55% in the 30-34 years age-group. The mean prevalence rate in women was 5.35%, with a peak of 6.59% in the same age-group. Type HIV-1 was predominant (84.2% of the total). The most affected area was Dabou, with a rate three times higher (15.83%) than the average rate observed during the study. More educated people (university level) presented 3.5-fold (for men) or 6-fold (for women) higher infection rates than illiterate people. Although 100% of people who tested positive received a medical or community referral according to their specific needs, only 62.1% were first-line referred for medical care. In the light of the results of this study, we believe that community mobilization must be redirected to the most severely affected populations to facilitate earlier diagnosis. Actions such as training and prevention based on communication to encourage changes of behaviour should therefore be priorities in the national counselling and testing programme.

Full Text Available BACKGROUND: Schistosomiasis and soil-transmitted helminthiasis are important public health problems in sub-Saharan Africa causing malnutrition, anemia, and retardation of physical and cognitive development. However, the effect of these diseases on physical fitness remains to be determined. METHODOLOGY: We investigated the relationship between schistosomiasis, soil-transmitted helminthiasis and physical performance of children, controlling for potential confounding of Plasmodium spp. infections and environmental parameters (i.e., ambient air temperature and humidity. A cross-sectional survey was carried out among 156 school children aged 7-15 years from Côte d'Ivoire. Each child had two stool and two urine samples examined for helminth eggs by microscopy. Additionally, children underwent a clinical examination, were tested for Plasmodium spp. infection with a rapid diagnostic test, and performed a maximal multistage 20 m shuttle run test to assess their maximal oxygen uptake (VO(2 max as a proxy for physical fitness. PRINCIPAL FINDINGS: The prevalence of Schistosoma haematobium, Plasmodium spp., Schistosoma mansoni, hookworm and Ascaris lumbricoides infections was 85.3%, 71.2%, 53.8%, 13.5% and 1.3%, respectively. Children with single, dual, triple, quadruple and quintuple species infections showed VO(2 max of 52.7, 53.1, 52.2, 52.6 and 55.6 ml kg(-1 min(-1, respectively. The VO(2 max of children with no parasite infections was 53.5 ml kg(-1 min(-1. No statistically significant difference was detected between any groups. Multivariable analysis revealed that VO(2 max was influenced by sex (reference: female, coef. = 4.02, p<0.001 and age (years, coef. = -1.23, p<0.001, but not by helminth infection and intensity, Plasmodium spp. infection, and environmental parameters. CONCLUSION/SIGNIFICANCE: School-aged children in Côte d'Ivoire showed good physical fitness, irrespective of their helminth infection status. Future studies on children

Characterization of arboviruses at the interface of pristine habitats and anthropogenic landscapes is crucial to comprehensive emergent disease surveillance and forecasting efforts. In context of a surveillance campaign in and around a West African rainforest, particles morphologically consistent with rhabdoviruses were identified in cell cultures infected with homogenates of trapped mosquitoes. RNA recovered from these cultures was used to derive the first complete genome sequence of a rhabdovirus isolated from Culex decens mosquitoes in Côte d'Ivoire, tentatively named Moussa virus (MOUV). MOUV shows the classical genome organization of rhabdoviruses, with five open reading frames (ORF) in a linear order. However, sequences show only limited conservation (12-33% identity at amino acid level), and ORF2 and ORF3 have no significant similarity to sequences deposited in GenBank. Phylogenetic analysis indicates a potential new species with distant relationship to Tupaia and Tibrogargan virus.

2009-01-01

In the nights of 19 to 21 August, 2006, highly toxic waste products were dumped at various sites in Abidjan, and numerous cases of poisoning were reported to the health authorities, who were unprepared for such a problem. The research group on Environment and Health in Urban Environment from the Swiss Center of Scientific Research and its partners at the Swiss Tropical Institute undertook this study whose objectives were to: describe the epidemiologic profile of the people poisoned; identify the main clinical symptoms and the risk factors for poisoning; and recommend steps to attenuate the effects and to prevent intermediate- and long-term consequences. This cross-sectional study examined the populations living around the discharge sites (n=6). The sample size was calculated at 619 people per site, to identify a 1% risk and a standard error of 0.4%, because of variability of the human impact factor at the different sites. Households were chosen at each site by the transect technique. Six teams, each including a physician, a public health agent and a local guide collected the data, after specific training. A pilot investigation made it possible to validate the final questionnaire. Of 4573 people surveyed, 4344 people, about 95%, were home during the toxic waste discharge. In all, 2369 (51.8%) had signs of poisoning. Sex, district of residence, and presence at home at the time of the discharge were all statistically related to poisoning. The distribution of poison victims according to health centre shows that 1297 people (64.4%) visited a health center AA(3/4) 615 of them (about 47.4%) a public or official centre, and 778 (about 60%), an unofficial centre; 379 (29.2%) were managed by an NGO, 159 individuals (12.3%) by mobile units, 63 individuals (4.8%) by the unofficial public health centre, and 35 (2.7%) at an unspecified site. Of those who sought care, 673 people (about 51.8%) received a medical prescription, and 815 (or 62.7%) had been given the drug directly

Antepartum depression and anxiety associated with disability in African women: cross-sectional results from the CDS study in Ghana and Côte d'Ivoire.

Directory of Open Access Journals (Sweden)

Carola Bindt

Full Text Available BACKGROUND: Common mental disorders, particularly unipolar depressive disorders, rank among the top 5 with respect to the global burden of disease. As a major public health concern, antepartum depression and anxiety not only affects the individual woman, but also her offspring. Data on the prevalence of common mental disorders in pregnant women in sub-Saharan Africa are scarce. We provide results from Ghana and Côte d'Ivoire. METHODS: We subsequently recruited and screened n = 1030 women in the third trimester of their pregnancy for depressed mood, general anxiety, and perceived disability using the Patient Health Questionnaire depression module (PHQ-9, the 7-item Anxiety Scale (GAD-7, and the World Health Organisation Disability Assessment Schedule II (WHO-DAS 2.0, 12-item version. In addition to estimates of means and prevalence, a hierarchical linear regression model was calculated to determine the influence of antepartum depression and anxiety on disability. RESULTS: In Ghana, 26.6% of women showed substantially depressed mood. In Côte d'Ivoire, this figure was even higher (32.9%. Clear indications for a generalized anxiety disorder were observed in 11.4% and 17.4% of pregnant women, respectively. Comorbidity of both conditions was common, affecting about 7.7% of Ghanaian and 12.6% of Ivorian participants. Pregnant women in both countries reported a high degree of disability regarding everyday activity limitations and participation restrictions. Controlled for country and age, depression and anxiety accounted for 33% of variance in the disability score. CONCLUSIONS: Antepartum depression and anxiety were highly prevalent in our sample and contributed substantially to perceived disability. These serious threats to health must be further investigated and more data are needed to comprehensively quantify the problem in sub-Saharan Africa.

Communications in case of radiological emergency: expertise exchange between IPSN and two agricultural branches of the region Provence-Alpes-Cote d'Azur

Berthier, Laure; Pupin, Vincent

1997-01-01

A patrimonial audit organized by the 'Institut de Protection et de Surete Nucleaire' (IPSN) has mobilized the expertise of specialists in the nuclear sector and two sensible agricultural branches (salads and sheep) in Province-Alpes-Cote d'Azur (PACA) on the topic of communications among them in case of contamination of region (radiological emergency situation). Having in view their offers and requests of information we have identified the common fields of action involving the four concerned high-ranking actors of different culture: agricultural Administration, agricultural professionals, nuclear sector authorities and elected persons. We have analyzed the actions already completed in this field and established that the Chernobyl accident was a graveyard from the point of view of mobilization and awareness of actors. A project in the future allowed the determination of the stake implied in the relation between IPSN and the two branches and thus to establish the conditions of reaction in case of radiological emergency. Hence, we were able to make propositions to IPSN for building a French agro-nuclear expertise based upon a relation network covering (and even surpassing) the studied agricultural branches

Helminth infection intensities were generally very low. Seven, 74 and 79 participants belonged to three different treatment groups. Multivariable logistic regression models revealed statistically significant (p<0.05 associations between some risk factors, signs, and symptoms, and the different helminth infections and treatment groups. However, the risk factors, signs, and symptoms showed weak diagnostic properties. CONCLUSIONS

Le sujet de cette these concerne la modelisation numerique du climat regional. L'objectif principal de l'exercice est de developper un modele climatique regional ayant les capacites de simuler des phenomenes de meso-echelle spatiale. Notre domaine d'etude se situe sur la Cote Ouest nord americaine. Ce dernier a retenu notre attention a cause de la complexite du relief et de son controle sur le climat. Les raisons qui motivent cette etude sont multiples: d'une part, nous ne pouvons pas augmenter, en pratique, la faible resolution spatiale des modeles de la circulation generale de l'atmosphere (MCG) sans augmenter a outrance les couts d'integration et, d'autre part, la gestion de l'environnement exige de plus en plus de donnees climatiques regionales determinees avec une meilleure resolution spatiale. Jusqu'alors, les MCG constituaient les modeles les plus estimes pour leurs aptitudes a simuler le climat ainsi que les changements climatiques mondiaux. Toutefois, les phenomenes climatiques de fine echelle echappent encore aux MCG a cause de leur faible resolution spatiale. De plus, les repercussions socio-economiques des modifications possibles des climats sont etroitement liees a des phenomenes imperceptibles par les MCG actuels. Afin de circonvenir certains problemes inherents a la resolution, une approche pratique vise a prendre un domaine spatial limite d'un MCG et a y imbriquer un autre modele numerique possedant, lui, un maillage de haute resolution spatiale. Ce processus d'imbrication implique alors une nouvelle simulation numerique. Cette "retro-simulation" est guidee dans le domaine restreint a partir de pieces d'informations fournies par le MCG et forcee par des mecanismes pris en charge uniquement par le modele imbrique. Ainsi, afin de raffiner la precision spatiale des previsions climatiques de grande echelle, nous developpons ici un modele numerique appele FIZR, permettant d'obtenir de l'information climatique regionale valide a la fine echelle spatiale

Full Text Available BACKGROUND: Helminth infection and malaria remain major causes of ill-health in the tropics and subtropics. There are several shared risk factors (e.g., poverty, and hence, helminth infection and malaria overlap geographically and temporally. However, the extent and consequences of helminth-Plasmodium co-infection at different spatial scales are poorly understood. METHODOLOGY: This study was conducted in 92 schools across Côte d'Ivoire during the dry season, from November 2011 to February 2012. School children provided blood samples for detection of Plasmodium infection, stool samples for diagnosis of soil-transmitted helminth (STH and Schistosoma mansoni infections, and urine samples for appraisal of Schistosoma haematobium infection. A questionnaire was administered to obtain demographic, socioeconomic, and behavioral data. Multinomial regression models were utilized to determine risk factors for STH-Plasmodium and Schistosoma-Plasmodium co-infection. PRINCIPAL FINDINGS: Complete parasitological and questionnaire data were available for 5,104 children aged 5-16 years. 26.2% of the children were infected with any helminth species, whilst the prevalence of Plasmodium infection was 63.3%. STH-Plasmodium co-infection was detected in 13.5% and Schistosoma-Plasmodium in 5.6% of the children. Multinomial regression analysis revealed that boys, children aged 10 years and above, and activities involving close contact to water were significantly and positively associated with STH-Plasmodium co-infection. Boys, wells as source of drinking water, and water contact were significantly and positively associated with Schistosoma-Plasmodium co-infection. Access to latrines, deworming, higher socioeconomic status, and living in urban settings were negatively associated with STH-Plasmodium co-infection; whilst use of deworming drugs and access to modern latrines were negatively associated with Schistosoma-Plasmodium co-infection.

Early detection of several skin-related neglected tropical diseases (skin NTDs)-including leprosy, Buruli ulcer, yaws, and scabies- may be achieved through school surveys, but such an approach has seldom been tested systematically on a large scale in endemic countries. Additionally, a better understanding of the spectrum of skin diseases and the at-risk populations to be encountered during such surveys is necessary to facilitate the process. We performed a school skin survey for selected NTDs and the spectrum of skin diseases, among primary schoolchildren aged 5 to 15 in Côte d'Ivoire, West Africa. This 2-phase survey took place in 49 schools from 16 villages in the Adzopé health district from November 2015 to January 2016. The first phase involved a rapid visual examination of the skin by local community healthcare workers (village nurses) to identify any skin abnormality. In a second phase, a specialized medical team including dermatologists performed a total skin examination of all screened students with any skin lesion and provided treatment where necessary. Of a total of 13,019 children, 3,504 screened positive for skin lesions and were listed for the next stage examination. The medical team examined 1,138 of these children. The overall prevalence of skin diseases was 25.6% (95% CI: 24.3-26.9%). The predominant diagnoses were fungal infections (n = 858, prevalence: 22.3%), followed by inflammatory skin diseases (n = 265, prevalence: 6.9%). Skin diseases were more common in boys and in children living along the main road with heavy traffic. One case of multi-bacillary type leprosy was detected early, along with 36 cases of scabies. Our survey was met with very good community acceptance. We carried out the first large-scale integrated, two-phase pediatric multi-skin NTD survey in rural Côte d'Ivoire, effectively reaching a large population. We found a high prevalence of skin diseases in children, but only limited number of skin NTDs. With the lessons learned

Given the broad commercial applications for ZnO nanomaterials, accurate attribution of physicochemical characteristics that induce toxic effects is particularly important. We report on the physicochemical properties of three commercial nano-ZnO products: Z-COTE and Z-COTE HP1 from BASF, and Nanosun from Micronisers, and, for reference, "bulk" ZnO from Sigma-Aldrich. Z-COTE, Nanosun and "bulk" consist of uncoated particles with different sizes, while Z-COTE HP1 consists of nanoparticles with a hydrophobic coating. Specific batches of these ZnO products were included in the OECD Sponsorship Programme to test manufactured nanomaterials. In order to identify properties potentially susceptible to variations between production runs, three additional batches of Z-COTE and Nanosun and two additional batches of Z-COTE HP1 were also investigated here. In general, all products showed little variation between batches for properties measured from powdered samples, but batch variations in the amount of surface coating were evident for the coated Z-COTE HP1. Properties measured with samples dispersed in liquids (agglomeration, photocatalytic activity, dissolution) were highly dependent on dispersion protocols, and this made it difficult to differentiate between differences due to dispersion and due to batches. However, batch-sensitive properties did appear to be present in Z-COTE and Z-COTE HP1 (photocatalytic activity), and Nanosun (dissolution). Intra-batch time and/or storage-dependent changes in the applied surface coating, noted specifically for the OECD batch of Z-COTE HP1, highlight the need for best practice when storing and accessing stocks of nano products. Awareness of inter-batch and intra-batch variability is essential for commercial applications and for nanotoxicological studies aimed at identifying links between physicochemical properties and any adverse effects in biological systems.

Restoration of soil fertility and improvement of cropping systems for sustainable development in the humid savannahs of Cote d'Ivoire

1999-01-01

The present FAO-project addresses the soil fertility problems by combining organic with inorganic nutrient sources and actively involving farmers and other beneficiaries in an integrated, long-term development process. A major objective of the project is the participatory on-farm testing and validation of available technological innovations for soil fertility improvement. The results should fulfill two main requirements: (i) provide the farmer with a short-term production increase and (ii) improve/maintain soil fertility in the medium and long-term. The strategic framework of the project is based on the following three main elements: the need to take into account all aspects of soil fertility restoration including areas concerned, cost of fertility restoration, and economic profitability and sustainability; - the need to test all fertility improving measures at farm level in representative agro-ecozones of the humid and sub-humid savannas before their extension at large; the need to identify major macro-economic constraints (e.g. marketing) which impede sustainable agricultural development in the savannah region. The primary goal of the project is to replace traditional shifting cultivation in the humid savannas of the country by economically, ecologically and socially more sustainable production systems. In order to achieve this development objective the project focuses on the following main issues: restoration of soil fertility through improved land and crop management and more efficient use of mineral and organic fertilizers; crop diversification through more efficient use of water resources (irrigation); introduction of new cropping systems which have been successfully tested in countries with similar agro-ecological conditions; adapting traditional land tenure to the market economy; involving the private sector in all aspects of regional development assisted by Government through the creation of a favorable environment. Phase 1: constraint analysis and formulation of a pilot project to be financed by donors; Phase 2: implementation of the pilot project (1999-2003) including a mid-term evaluation; Phase 3: long-term extension phase (15 years) starting in 2004, based on successful results of the pilot phase. The on-going first (diagnostic) phase is expected to produce the following results: methodological guidelines for the identification of constraints and test zones (agro-ecological zones and their fertility criteria) and the formulation of technological options for the improvement of soil and crop productivity; a document for negotiating the pilot project; a regional development program proposal with a particular focus on institutional support and crops with agro-industrial development potential (e.g. maize, soybean and groundnuts)

To determine whether a possession score or a poverty index best predicts undernutrition and anaemia in women of reproductive age (15-49 years; WRA) and children aged 6-59 months living in Côte d'Ivoire. Anthropometric measurements were converted to Z-scores to assess stunting, wasting and underweight in children, and converted to BMI in WRA. A venous blood sample was drawn, and Hb concentration and Plasmodium spp. infection were determined. A possession score was generated with categories of zero to four possessions. A five-point (quintile) poverty index using household assets was created using principal component analysis. These socio-economic measures were compared for their ability to predict anaemia and malnutrition. Data were from a nationally representative survey conducted in Côte d'Ivoire in 2007. A sample of 768 WRA and 717 children aged 6-59 months was analysed. Overall, 74·9 % of children and 50·2 % of WRA were anaemic; 39·5 % of the children were stunted, 28·1 % underweight and 12·8 % wasted, while 7·4 % of WRA had BMI poverty index showed a stronger relationship with nutritional status than the possession score; mean Hb difference between the poorest and wealthiest quintiles in children and WRA was 8·2 g/l and 6·5 g/l, respectively (13·9 % and 19·8 % difference in anaemia, respectively; P poverty index was generally a better predictor of undernutrition in WRA and pre-school children than the possession score.

The main objective of this study is to give an insight on possible effects climate change may have on landscapes of the Provence-Alpes-Cote d'Azur region on the medium and long term according to current hypotheses regarding global warming for Mediterranean regions. A first phase aimed at identifying the main landscape settings of the region. This comprised a definition of the notion of landscape, a discussion of landscape definitions with respect to a regional scale, a framework for the definition of the main landscape settings, an identification of these landscape settings and their characterisation according to a set of criteria and parameters. The second phase aimed at giving an overview of hypotheses regarding climate change. The authors discuss various issues and knowledge about the world climate, available climate models and their uncertainties, and climatic predictions for the region. The third phase aimed at assessing predictable effects of climate change on emblematic landscapes and at defining actions plans. The different components of these action plans are then discussed for the identified landscapes for which the landscape context and challenges are described, and potential actors are indicated. These different phases are first presented, and more detailed reports are provided for each of them, notably with detailed reports and sheets for each landscape setting

Quantitative targets in DND and ICPD-PA: the prospects for West Africa.

Science.gov (United States)

1999-01-01

This article presents an overview of the population estimates and projections of the UN for total fertility rates (TFRs), contraceptive prevalence rates, infant mortality rates (IMRs), and life expectancy at birth (LEAB) in West Africa. Countries with a good potential to reach a TFR of 4 children or less within 10-15 years are Cote d'Ivoire, Ghana, Nigeria, and perhaps Gambia and Guinea, while the TFRs of countries such as Niger and Mali will remain above 5 in the coming decade. Low contraceptive prevalence is one of the reasons behind the slow progress in attaining low fertility levels in the subregion. When basing the data on this indicator, it appears that only Ghana and Cape Verde will attain the target of 20% by the year 2000 and 40% by the year 2010. Moreover, IMRs will continue to decline, but none of the West African countries will reach the quantitative objectives set in the Dakar/Ngor Declaration (DND) and in the International Conference on Population and Development Programme of Action (ICPD-PA). Similarly, considerable improvements will be seen in the LEAB during the next decade, but, with the exception of Cape Verde and Ghana, none of the other countries are expected to come close to the goals set in the DND and ICPD-PA.

Full Text Available Health facility characteristics associated with effective prevention of mother-to-child transmission of HIV (PMTCT coverage in sub-Saharan are poorly understood.We conducted surveys in health facilities with active PMTCT services in Cameroon, Cote d'Ivoire, South Africa, and Zambia. Data was compiled via direct observation and exit interviews. We constructed composite scores to describe provision of PMTCT services across seven topical areas: antenatal quality, PMTCT quality, supplies available, patient satisfaction, patient understanding of medication, and infrastructure quality. Pearson correlations and Generalized Estimating Equations (GEE to account for clustering of facilities within countries were used to evaluate the relationship between the composite scores, total time of visit and select individual variables with PMTCT coverage among women delivering. Between July 2008 and May 2009, we collected data from 32 facilities; 78% were managed by the government health system. An opt-out approach for HIV testing was used in 100% of facilities in Zambia, 63% in Cameroon, and none in Côte d'Ivoire or South Africa. Using Pearson correlations, PMTCT coverage (median of 55%, (IQR: 33-68 was correlated with PMTCT quality score (rho = 0.51; p = 0.003; infrastructure quality score (rho = 0.43; p = 0.017; time spent at clinic (rho = 0.47; p = 0.013; patient understanding of medications score (rho = 0.51; p = 0.006; and patient satisfaction quality score (rho = 0.38; p = 0.031. PMTCT coverage was marginally correlated with the antenatal quality score (rho = 0.304; p = 0.091. Using GEE adjustment for clustering, the, antenatal quality score became more strongly associated with PMTCT coverage (p<0.001 and the PMTCT quality score and patient understanding of medications remained marginally significant.We observed a positive relationship between an antenatal quality score and PMTCT coverage but did not identify

To achieve a world free of schistosomiasis, the objective is to scale up control and elimination efforts in all endemic countries. Where interruption of transmission is considered feasible, countries are encouraged to implement a comprehensive intervention package, including preventive chemotherapy, information, education and communication (IEC), water, sanitation and hygiene (WASH), and snail control. In northern and central Côte d'Ivoire, transmission of Schistosoma haematobium is seasonal and elimination might be achieved. In a cluster-randomised trial, we will assess different treatment schemes to interrupt S. haematobium transmission and control soil-transmitted helminthiasis over a 3-year period. We will compare the impact of (i) arm A: annual mass drug administration (MDA) with praziquantel and albendazole before the peak schistosomiasis transmission season; (ii) arm B: annual MDA after the peak schistosomiasis transmission season; (iii) arm C: two yearly treatments before and after peak schistosomiasis transmission; and (iv) arm D: annual MDA before peak schistosomiasis transmission, coupled with chemical snail control using niclosamide. The prevalence and intensity of S. haematobium and soil-transmitted helminth infections will be assessed using urine filtration and Kato-Katz thick smears, respectively, in six administrative regions in northern and central parts of Côte d'Ivoire. Once a year, urine and stool samples will be collected and examined from 50 children aged 5-8 years, 100 children aged 9-12 years and 50 adults aged 20-55 years in each of 60 selected villages. Changes in S. haematobium and soil-transmitted helminth prevalence and intensity will be assessed between years and stratified by intervention arm. In the 15 villages randomly assigned to intervention arm D, intermediate host snails will be collected three times per year, before niclosamide is applied to the selected freshwater bodies.

Insecticide resistance in malaria vectors is an increasing threat to vector control tools currently deployed in endemic countries. Resistance management must be an integral part of National Malaria Control Programmes' (NMCPs) next strategic plans to alleviate the risk of control failure. This obviously will require a clear database on insecticide resistance to support the development of such a plan. The present work gathers original data on insecticide resistance between 2009 and 2015 across Côte d'Ivoire in West Africa. Two approaches were adopted to build or update the resistance data in the country. Resistance monitoring was conducted between 2013 and 2015 in 35 sentinel sites across the country using the WHO standard procedure of susceptibility test on adult mosquitoes. Four insecticide families (pyrethroids, organochlorides, carbamates and organophosphates) were tested. In addition to this survey, we also reviewed the literature to assemble existing data on resistance between 2009 and 2015. High resistance levels to pyrethroids, organochlorides and carbamates were widespread in all study sites whereas some Anopheles populations remained susceptible to organophosphates. Three resistance mechanisms were identified, involving high allelic frequencies of kdr L1014F mutation (range = 0.46-1), relatively low frequencies of ace-1 R (below 0.5) and elevated activity of insecticide detoxifying enzymes, mainly mixed function oxidases (MFO), esterase and glutathione S-transferase (GST) in almost all study sites. This detailed map of resistance highlights the urgent need to develop new vector control tools to complement current long-lasting insecticidal nets (LLINs) although it is yet unclear whether these resistance mechanisms will impact malaria transmission control. Researchers, industry, WHO and stakeholders must urgently join forces to develop alternative tools. By then, NMCPs must strive to develop effective tactics or plans to manage resistance keeping in mind

Despite a growing awareness of the increased prevalence of intimate partner violence and sexual violence in conflict and post-conflict settings, much less is known about the dynamics, as well as the interventions that would be effective at individual, relational, and structural levels. In addition to the human capital lost by conflict violence, gender-based violence (GBV) poses a grave threat to the post-conflict rehabilitation process. With regard to violence that occurs during and post conflict, research must take into consideration the different types of violence that share similar causes as the larger conflict as well as become widespread as a result of the conflict and use existing frameworks to build future interventions. Researchers are trying to understand the interplay of personal, situational, and socio-cultural factors in conflict settings that combine to cause GBV and lead to guidelines for program planning to address the health and social needs of survivors as well as to prevent further GBV. These actions result from a growing recognition that violence represents a serious public health problem, is an important cause of many physical and psychological illnesses, and can cause social disruptions that impede reconstruction efforts for generations. This review studies the manifestations of GBV during and following the Ivoirian Civil War, juxtaposes them against narratives, as well as lists relevant interventions at the individual, relational, community, and institutional levels. Part of a growing literature that aims to better understand the nature of violence during and after conflict and to plan effective responses to it, this study hopes to suggest solutions for the situation of Côte d'Ivoire and elsewhere.

The purpose of this study was to assess hepatitis B knowledge among secondary school students' in Côte d'Ivoire in order to promote the inclusion of hepatitis B education in school curricula. a single cross-sectional survey involving six schools (7,376 students) was conducted. Data were collected using a self-administered questionnaire. All students present on the day of the survey agreed to participate in the study (100%, n = 3,352). The mean age of the participants was 17.9 years (10-26 years), with a male-to-female sex ratio of 1.68. Among them, 2,552 (76.6%) had heard of the HVB. School was the main source of information (12%), after the mass media (62%). The causative agent of the disease was known by 74.1% of students (n = 2,484), sexual transmission by 39.3% (n = 1316), and blood-borne transmission by 57.2% (n = 1919). Respectively 29%, 40% and 41% of the students were aware that acupuncture, body piercing and tattooing are high-risk practices. Only 35.7% of the students knew that there was an effective vaccine. The factors associated with hepatitis B knowledge were: being aged 16 to 20 years (OR = 1.73 [95% CI 1.198 to 2.49]), living in a permanent house or apartment (OR = 1.58 [95% CI 1.234 to 2.02]) or in a house or apartment with no more than 2 persons per room (OR = 1.41 [95% CI 1.15 to 1.74]), being in terminale (final year of high school) (OR = 2.54 [2.01 to 3, 20IC95%]), and having two working parents (OR =1.54 [95% CI 1.25 to 1.88]). The students' knowledge of the hepatitis B virus was found to be inadequate and superficial. Early awareness programs provided as part of the official curriculum and measures to improve the social conditions of students should help to improve knowledge in this area.

Human and animal Trypanosomes in Côte d'Ivoire form a single breeding population.

Directory of Open Access Journals (Sweden)

Paul Capewell

Full Text Available Trypanosoma brucei is the causative agent of African Sleeping Sickness in humans and contributes to the related veterinary disease, Nagana. T. brucei is segregated into three subspecies based on host specificity, geography and pathology. T. b. brucei is limited to animals (excluding some primates throughout sub-Saharan Africa and is non-infective to humans due to trypanolytic factors found in human serum. T. b. gambiense and T. b. rhodesiense are human infective sub-species. T. b. gambiense is the more prevalent human, causing over 97% of human cases. Study of T. b. gambiense is complicated in that there are two distinct groups delineated by genetics and phenotype. The relationships between the two groups and local T. b. brucei are unclear and may have a bearing on the evolution of the human infectivity traits.A collection of sympatric T. brucei isolates from Côte d'Ivoire, consisting of T. b. brucei and both groups of T. b. gambiense have previously been categorized by isoenzymes, RFLPs and Blood Incubation Infectivity Tests. These samples were further characterized using the group 1 specific marker, TgSGP, and seven microsatellites. The relationships between the T. b. brucei and T. b. gambiense isolates were determined using principal components analysis, neighbor-joining phylogenetics, STRUCTURE, FST, Hardy-Weinberg equilibrium and linkage disequilibrium.Group 1 T. b. gambiense form a clonal genetic group, distinct from group 2 and T. b. brucei, whereas group 2 T. b. gambiense are genetically indistinguishable from local T. b. brucei. There is strong evidence for mating within and between group 2 T. b. gambiense and T. b. brucei. We found no evidence to support the hypothesis that group 2 T. b. gambiense are hybrids of group 1 and T. b. brucei, suggesting that human infectivity has evolved independently in groups 1 and 2 T. b. gambiense.

Full Text Available Abstract Background Pyrethroid resistance in vectors could limit the efficacy of long-lasting insecticidal nets (LLINs because all LLINs are currently treated with pyrethroids. The goal of this study was to evaluate the efficacy and wash resistance of PermaNet® 3.0 compared to PermaNet® 2.0 in an area of high pyrethroid in Côte d'Ivoire. PermaNet® 3.0 is impregnated with deltamethrin at 85 mg/m2 on the sides of the net and with deltamethrin and piperonyl butoxide on the roof. PermaNet® 2.0 is impregnated with deltamethrin at 55 mg/m2 across the entire net. Methods The study was conducted in the station of Yaokoffikro, in central Côte d'Ivoire. The efficacy of intact unwashed and washed LLINs was compared over a 12-week period with a conventionally-treated net (CTN washed to just before exhaustion. WHO cone bioassays were performed on sub-sections of the nets, using wild-resistant An. gambiae and Kisumu strains. Mosquitoes were collected five days per week and were identified to genus and species level and classified as dead or alive, then unfed or blood-fed. Results Mortality rates of over 80% from cone bioassays with wild-caught pyrethroid-resistant An. gambiae s.s were recorded only with unwashed PermaNet® 3.0. Over 12 weeks, a total of 7,291 mosquitoes were collected. There were significantly more An. gambiae s.s. and Culex spp. caught in control huts than with other treatments (P An. gambiae s.s and Culex spp, were lower for the control than for other treatments (P 0.05 except for unwashed PermaNet® 3.0 (P Conclusions This study showed that unwashed PermaNet® 3.0 caused significantly higher mortality against pyrethroid resistant An. gambiae s.s and Culex spp than PermaNet® 2.0 and the CTN. The increased efficacy with unwashed PermaNet® 3.0 over PermaNet® 2.0 and the CTN was also demonstrated by higher KD and mortality rates (KD > 95% and mortality rate > 80% in cone bioassays performed with wild pyrethroid-resistant An. gambiae s

The first part of this document aims at presenting perspectives of emergence of new energy production, consumption and storage sources, and their impacts on energy (electricity, gas, heat) distribution and transport networks. It is based on two scenarios: the regional climate-air-energy scheme, and the regional Negawatt scenario. The objective was to select a limited number of aspects: solutions enabling an optimal injection of biogas produced in the concerned region, development of photovoltaic energy and electric vehicles and their impact on the balance of medium-voltage and low-voltage networks, and smart grid technologies and their possible impact on the optimisation of electric network management. The second part reports the detailed study of these issues. It more particularly addresses technical impacts of different sectors on electric and gas networks in Provence-Alpes-Cote d'Azur, technical, economic and organisational assets of smart grid technologies, investments policies and implementation planning, and resulting evolutions for energy markets.

Millions of people are already affected by weather-related shocks every year in West Africa and climate change is highly likely to increase these threats. In the wake of climate change, rising temperatures, increasingly irregular rainfall and more frequent natural hazards will endanger the ways of life of vulnerable population groups in this region and destabilize their human security. A surge in violence and conflicts could take place. One of the conflict constellations could be between farmers and herders. These groups are highly vulnerable to climate change due to their dependence on natural resources Millions of people are already affected by weather-related shocks every year in West Africa and climate change is highly likely to increase these threats. In the wake of climate change, rising temperatures, increasingly irregular rainfall and more frequent natural hazards will endanger the ways of life of vulnerable population groups in this region and destabilize their human security. A surge in violence and conflicts could take place. One of the conflict constellations could be between farmers and herders. These groups are highly vulnerable to climate change due to their dependence on natural resources for their subsistence. Furthermore, they are historically prone to enter into conflict over issues of access to natural resources. However, social, economic and political circumstances fundamentally influence environmental conflicts. There might thus be opportunities to face the societal challenges of climate change in a peaceful way and the political and institutional framework could play an important role in reducing conflict and violence. In order to explore such a path, this study analyses the potential of political factors (policies and institutions) for the reduction of climate-change-induced or aggravated conflicts between farmers and herders. After a theoretical demonstration, a case study of agro-pastoral conflicts in Burkina Faso, Cote d'Ivoire, and

Study of the impact of food irradiation on preventing losses: Experience in Africa. Proceedings of a final research co-ordination meeting

There have been positive developments on food irradiation in different regions of the world, especially in the United States of America and several Asian and Latin American countries. In some countries in Africa, this technology has been studied in the past few decades with encouraging results. To assist these countries in conducting pilot scale research and development on irradiation of specific commodities of interest to them including market testing and feasibility to establish commercial irradiators for multi-purpose application, a Coordinated Research Project (CRP) on Impact of Irradiation to Prevent Food Losses in Africa was carried out between 1995 and 1999. This CRP demonstrated that food irradiation has a potential to reduce losses of basic staple food crops including yams, dried and smoked fish, potatoes and onions through pilot scale experiments carried out in some African countries. Small scale market testing of such irradiated food such as spices, potatoes and onions showed encouraging results. In some countries (Cote d'Ivoire, Egypt, Ghana, Senegal and South Africa), it is feasible to establish commercial irradiation facilities for treating food. In Morocco, irradiation shows a potential to meet quarantine requirements in international food trade. It should be noted that commercial scale application of irradiation of some food products has been carried out in South Africa since the 1980s

High nitrate contents (up to 200 mgl) has been observed in wells drilled into fractured aquifers lying beneath layers of weathered and decayed rock in the humid tropics where annual rainfall is over 1,000 mm and where there is no notable pollution. The source of the nitrates is linked mainly with localized deforestation by man

Novel arenavirus sequences in Hylomyscus sp. and Mus (Nannomys setulosus from Côte d'Ivoire: implications for evolution of arenaviruses in Africa.

David Coulibaly-N'Golo

Full Text Available This study aimed to identify new arenaviruses and gather insights in the evolution of arenaviruses in Africa. During 2003 through 2005, 1,228 small mammals representing 14 different genera were trapped in 9 villages in south, east, and middle west of Côte d'Ivoire. Specimens were screened by pan-Old World arenavirus RT-PCRs targeting S and L RNA segments as well as immunofluorescence assay. Sequences of two novel tentative species of the family Arenaviridae, Menekre and Gbagroube virus, were detected in Hylomyscus sp. and Mus (Nannomys setulosus, respectively. Arenavirus infection of Mus (Nannomys setulosus was also demonstrated by serological testing. Lassa virus was not found, although 60% of the captured animals were Mastomys natalensis. Complete S RNA and partial L RNA sequences of the novel viruses were recovered from the rodent specimens and subjected to phylogenetic analysis. Gbagroube virus is a closely related sister taxon of Lassa virus, while Menekre virus clusters with the Ippy/Mobala/Mopeia virus complex. Reconstruction of possible virus-host co-phylogeny scenarios suggests that, within the African continent, signatures of co-evolution might have been obliterated by multiple host-switching events.

Poverty reduction policies guide development strategies. In economies that depend heavily on agriculture, in the face of rapid population growth, innovative approaches are required to satisfy food needs, increase household welfare and alleviate poverty. Irrigated agriculture is an important strategy to enhance crop production, but it must be well tailored to specific socio-ecological settings, as otherwise, it might increase the burden of water-related parasitic diseases and delay economic advance. The purpose of this study is to assess and quantify the effect of ill health, particularly malaria, on the performance of farm activity, with an emphasis on drip-irrigated vegetable farming in rural Côte d'Ivoire. Vegetable yields and revenues were monitored among 12 farmers and linked with longitudinal medical and entomological surveys. Over the course of 10 months, farmers were classified as sick, on average, for 14-15 days, with malaria accounting for 8-9 days (58%), confirming that malaria is the most important disease in this setting. There was a large heterogeneity among farmers, with malaria-related work losses ranging between 0 and 26 days. Work absenteeism correlated with overall yields and revenues. During a single cabbage production cycle, those farmers who were prescribed sick because of malaria for more than 2 days (mean: 4.2 days) had 47% lower yields and 53% lower revenues than farmers who missed a maximum of 2 days (mean: 0.3 days). This is consequential in an intensive cropping system, where substitutes for qualified workers are not readily available. We conclude that mitigating the burden of malaria is an important step towards reducing the vulnerability of people engaged in intensive agricultural production. This calls for targeted interventions to facilitate agriculture-based rural development that might spur social and economic development and reduce inequities in sub-Saharan Africa.

In August 2006, toxic wastes were discharged in the district of Abidjan, causing important health consequences in many households in the area. In order to appreciate the socio-economic impact of the consequences of toxic waste discharge on the households and of the measures taken by the authorities to deal with this catastrophe, and to appreciate the spatial extent of the pollution, we undertook a multidisciplinary transversal investigation at the sites of discharge of oxic waste, from October the 19th to December the 8th, 2006, using a transect sampling methodology. This paper presents the results related to the socio-economic aspects of the survey while the environmental and epidemiological results are presented in two other published papers. The socioeconomics investigation, conducted using a questionnaire, concerned 809 households across the various sites of discharge of toxic waste. More than 62% of households had at least one person who had been affected by toxic waste (affected households). 62.47% of these households were in Cocody district (with 2 sites and 4 points of discharge), 30.14% in Abobo district (with 2 sites and 3 points) and 7.39% in Koumassi district (with 1 site and 1 point). To escape the bad smell and the nuisance, 22.75% of the 501 "affected" households had left their houses. To face the health consequences generated by the toxic waste, 30.54% of the "affected" households engaged expenses. Those were on average of 92 450 FCFA (€141), with a minimum of 1 000 FCFA (€1.5) and a maximum of 1500000 FCFA (€2.287), in spite of the advertisement of the exemption from payment treatment fees made by the government. The decision of destroying cultures and farms near the points of discharge of the toxic products in a radius of 200 meters, taken by the authorities, touched 2.22% of the households. For these households, it did nothing but worsen their state of poverty, since the zone of influence of the toxic waste went well beyond the 200 meters

Poor waste management is a key driver of ill-health in urban settlements of developing countries. The current study aimed at assessing environmental and human health risks related to urban waste management in Yamoussoukro, the political capital of Côte d'Ivoire. We undertook trans-disciplinary research within an Ecohealth approach, comprised of a participatory workshop with stakeholders and mapping of exposure patterns. A total of 492 randomly selected households participated in a cross-sectional survey. Waste deposit sites were characterised and 108 wastewater samples were subjected to laboratory examinations. The physico-chemical parameters of the surface water (temperature, pH, conductivity, potential oxidise reduction, BOD5, COD, dissolved oxygen, nitrates, ammonia and total Kendal nitrogen) did not comply with World Health Organization standards of surface water quality. Questionnaire results showed that malaria was the most commonly reported disease. Diarrhoea and malaria were associated with poor sanitation. Households having dry latrines had a higher risk of diarrhoea (odds ratio (OR) = 1.8, 95% confidence interval (CI) 1.2-2.7) compared to latrines with septic tanks and also a higher risk for malaria (OR = 1.9, 95% (CI) 1.1-3.3). Our research showed that combining health and environmental assessments enables a deeper understanding of environmental threats and disease burdens linked to poor waste management. Further study should investigate the sanitation strategy aspects that could reduce the environmental and health risks in the study area.

Parasitic worms: knowledge, attitudes, and practices in Western Côte d'Ivoire with implications for integrated control.

Directory of Open Access Journals (Sweden)

Cinthia A Acka

Full Text Available BACKGROUND: In the developing world where parasitic worm infections are pervasive, preventive chemotherapy is the key strategy for morbidity control. However, local knowledge, attitudes, and practices (KAP of parasitic worms are poorly understood, although such information is required for prevention and sustainable control. METHODS: We carried out KAP surveys in two rural communities of Côte d'Ivoire that were subjected to school-based and community-based research and control activities. We used qualitative and quantitative methods. The former included observations, in-depth interviews with key informants, and focus group discussions with school children and adults. Quantitative methods consisted of a structured questionnaire administered to household heads. PRINCIPAL FINDINGS: Access to clean water was lacking in both communities and only a quarter of the households had functioning latrines. There was a better understanding of soil-transmitted helminthiasis than intestinal schistosomiasis, but community-based rather than school-based interventions appeared to improve knowledge of schistosomiasis. In the villages with community-based interventions, three-quarters of household interviewees knew about intestinal schistosomiasis compared to 14% in the village where school-based interventions were implemented (P<0.001. Whereas two-thirds of respondents from the community-based intervention village indicated that the research and control project was the main source of information, only a quarter of the respondents cited the project as the main source. CONCLUSIONS/SIGNIFICANCE: Preventive chemotherapy targeting school-aged children has limitations, as older population segments are neglected, and hence lack knowledge about how to prevent and control parasitic worm infections. Improved access to clean water and sanitation is necessary, along with health education to make a durable impact against helminth infections.

To describe the epidemiological and clinical parameters of conjunctival squamous cell carcinomas and their association with HIV-AIDS in the ophthalmology department of the university hospital of Treichville. This is a prospective and descriptive cross sectional study carried out in the ophthalmology department of the university hospital of Treichville from July 2007 to June 2011. Twenty-six (26) patients who were selected presented with a tumor of the globe and/or adnexa. A CT scan was performed in advanced cases. Histopathological examination of the surgical specimen was performed in all cases. HIV serology was performed after informed consent. All patients were referred to the oncology department of the university hospital of Treichville where a unit of care for HIV-positive patients with malignant tumors is available. Statistical analysis was performed using the software program EPI info version 6.0. We note a slight predominance of female patients 15 (57.69%) vs. 11 (42.3%) male patients. The mean age was 42.32 years, and 13 patients (50%) were between 25 and 45 years of age. Intraorbital tumors were the most common reason for consultation, i.e. 38.46%. Seventeen patients (65.38%) had no particular history. Nine patients (34.61%) were already on antiretroviral treatment on admission. Three patients, i.e. 11.54%, had already had tumor biopsy and/or evisceration. The mean duration of the disease before consultation in ophthalmology was 14.28 months. Localized limbal conjunctival tumors were found in 11 cases (42.38%). Advanced tumors with regional or cerebral extension accounted for 34.61% of cases. Six patients (23.078%) were HIV negative vs. 20 (76.92%) HIV positive patients. CD4 lymphocyte typing was performed in 17 patients (85%), and 45% had a CD4 count below 200. Only five patients were able to receive neoadjuvant chemotherapy, but three of them died. The average length of follow-up was 29 months. This study allowed us to establish a statistically significant link between HIV positive status of patients and the occurrence of squamous cell carcinoma, (P=10(-4)), as well as the decline in CD4 count and disease progression (p=10(-3)). The poor prognosis of conjunctival carcinoma reflects the low socioeconomic status of patients, physician under-staffing in our health care facilities, the prohibitive cost of anticancer drugs and the link between this disease and HIV-AIDS.

In 13 villages in the savannah zone and 21 villages in the forest zone of Côte d'Ivoire, the biting density of the principal malaria vector, Anopheles gambiae, was studied as a function of rice cultivation in the inland valleys in a 2-km radius around each village. In the savannah villages, during the main season cropping period, surface water on rice-cultivated and to a lesser extent on uncultivated inland valleys seems to contribute strongly to the A. gambiae population density. For the off-season cropping period (which starts after the first light rains in the savannah zone), correlations were weaker. Breeding sites other than in inland valleys may play an important role in the savannah zone. In the forest zone, however, the A. gambiae population density was strongly correlated with the surface water availability (SWA) in the rice-cultivated inland valleys, whereas the correlation with the SWA in other (uncultivated) inland valleys was weak. The requirement of sunlit breeding sites for A. gambiae might explain this difference between zones. In the forest zone, only inland valleys cleared for rice cultivation meet this requirement, whereas all other inland valleys are covered with dense vegetation. In the savannah zone, however, most undergrowth is burnt during the dry season, which permits sunlight to reach puddles resulting from the first rains.

Silica in invasive wetland plant species of lagoons, Côte d'Ivoire: Spatio-temporal patterns

Tropical wetlands are known to accumulate a large quantity of Biogenic Silica (BSi) produced by wetland plant species (Struyf et al., 2015), and approximately 70-80% of the total supply of Dissolved Si (DSi) to the coastal zone occurs in (sub) tropical river systems (Jennerjahn et al. 2006). However, the data at these latitudes are limited. Here, we present the BSi concentration from eleven invasive macrophyte species randomly collected in three small ( 800ha) lagoons of Côte d'Ivoire during 12 months. Our data showed a large spatio-temporal variability of BSi in the three lagoons with no consistent trends. In general, the BSi concentrations obtained were high and values ranged from 0 to 54 mg g-1 through the entire sampling period, with the highest values found in Acroceras zizaniodes (emergent species of Poaceae). In general, free floating species had significantly less BSi than emergent species (Pspecies of fern, Salviniaceae) at the young stage were similar to those found in the emergent species. Based on yearly averages, highest BSi values were observed in Kodjoboué lagoon, and the lowest in the Ono lagoon that is 80% covered by macrophytes. Moreover, the dissolved silica (DSi) concentrations were systematically higher in Ono Lagoon than in Kodjoboué Lagoon. We conclude that in an eutrophic system Si accumulating in aquatic macrophytes is not related to Si availability but to other environmental factors.

Military personnel are at particularly high risk of becoming infected with HIV because they are in the age group at highest risk for infection, age 15-24 years; they are away from home for long periods of time; many feel invulnerable and ready to take risks; there are usually prostitutes and drugs in military areas; and troops have cash, but maybe not condoms, in their pockets. The level of attention given to HIV/AIDS in the military has grown over the course of the last few international AIDS conferences. One roundtable on HIV/AIDS in the armed forces was held at the 11th International Conference on AIDS held in Vancouver during July 7-12, 1996. A large-scale survey reported at the conference found the level of sexual activity to be significantly higher among US military personnel than in the civilian population. Even the oldest soldiers reported higher levels of multiple partner sex habits than the most sexually active young men in the UK and France. The data further indicate that significant numbers of those men who were infected continued to knowingly have unprotected sex. Data from Angola, Cambodia, Cameroon, the Central African Republic, Congo, Cote d'Ivoire, Thailand, and Zimbabwe show significantly higher levels of HIV infection among military personnel compared to the civilian populations. The authors stress the important role the military can play in preventing the spread of HIV and the need to involve military personnel in AIDS prevention programs.

Securitization in the Brazilian Banking Industry: An Empirical Study

Directory of Open Access Journals (Sweden)

Umbelina Cravo Teixeira Lagioia

2009-05-01

Full Text Available Securitization is a modality of structured finance which allows a company to raise funds based on its receivables through capital markets. In Brazil, securitization was developed mostly in the form of mutual funds -- the FIDC, which raise money by issuing senior quotas for qualified investors, and subordinated cotes, usually bought by the company that originated the receivables. This paper evaluates the risk and return for both kinds of investors through a stochastic model with two main variables: interest rates and default rates. The model is still sensible to the characteristics of the fund, like the amount of subordinated cotes, the type of asset being securitized; and the amount of receivables in relation to the assets. Regarding the case of senior cotes, the risk of returns under the basic level of interest rates is highly improbable; and in the case of subordinated cotes, the risk of returns under the basic interest rate may be considered still low, due to the high spreads observed in the Brazilian financial market. The simulations indicated that under historically mean interest rate volatility the default rates are the main component of the total risk. Accordingly to the developed analysis of international standards of regulation, the Brazilian Central Bank imposes very strong capital requirements to banks that securitize their assets and purchase the corresponding subordinated cotes.

Parasites and infectious diseases are well-known threats to primate populations. The main objective of this study was to provide baseline data on fecal parasites in the cercopithecid monkeys inhabiting Côte d'Ivoire's Taï National Park. Seven of eight cercopithecid species present in the park were sampled: Cercopithecus diana, Cercopithecus campbelli, Cercopithecus petaurista, Procolobus badius, Procolobus verus, Colobus polykomos, and Cercocebus atys. We collected 3142 monkey stool samples between November 2009 and December 2010. Stool samples were processed by direct wet mount examination, formalin-ethyl acetate concentration, and MIF (merthiolate, iodine, formalin) concentration methods. Slides were examined under microscope and parasite identification was based on the morphology of cysts, eggs, and adult worms. A total of 23 species of parasites was recovered including 9 protozoa (Entamoeba coli, Entamoeba histolytica/dispar, Entamoeba hartmanni, Endolimax nana, Iodamoeba butschlii, Chilomastix mesnili, Giardia sp., Balantidium coli, and Blastocystis sp.), 13 nematodes (Oesophagostomum sp., Ancylostoma sp., Anatrichosoma sp., Capillariidae Gen. sp. 1, Capillariidae Gen. sp. 2, Chitwoodspirura sp., Subulura sp., spirurids [cf Protospirura muricola], Ternidens sp., Strongyloides sp., Trichostrongylus sp., and Trichuris sp.), and 1 trematode (Dicrocoelium sp.). Diversity indices and parasite richness were high for all monkey taxa, but C. diana, C. petaurista, C. atys, and C. campbelli exhibited a greater diversity of parasite species and a more equitable distribution. The parasitological data reported are the first available for these cercopithecid species within Taï National Park. © R.W.Y. Kouassi et al., published by EDP Sciences, 2015.

Hepatitis B virus (HBV) and human immunodeficiency virus (HIV) share common risk factors. The parallel description of their frequency over time may help capture their similarities and differences. Using data from the National Transfusion Center of Abidjan, we estimated the following over a 20-year period: (1) the prevalence of HIV and hepatitis B surface antigen (HBsAg) positivity at first contact; and (2) the incidence of HIV and HBsAg seroconversion in negative first-time blood donors. Between 1992 and 2012, 422319 donors (men [M] = 74%) provided 1063825 blood donations. For first-time donors, HIV prevalence decreased from 7.1% (M = 5.9%, women [W] =11.0%) in 1992-1994 to 1.1% (M = 0.8%, W = 2.0%) in 2010-2012. Prevalence of HBsAg positivity remained stable at 10.8% (M = 11.7%, W = 7.3%) in 1992-1994 to 11.1% (M = 12.5%, W = 7.1%) in 2010-2012. Among regular donors (N = 129256), the incidence of becoming HIV or HBsAg positive, respectively, decreased from 4.9 per 100 (M = 4.5, W = 8.6) and 7.3 per 100 person-years (M = 7.8, W = 2.3) in 1992-1994 to 0.07 (M = 0.06, W = 0.11) and 0.2 per 100 person-years (M = 0.2, W = 0.2) in 2010-2012. Human immunodeficiency virus prevalence and incidence decreased dramatically over time, whereas HBV prevalence remained stable. Incidence of HBsAg seroconversion, although decreasing, still reached unexpected levels, suggesting that the risk of HBV infection in adults may be higher than expected. Hepatitis B surface antigen-negative blood-donors should be offered HBV vaccination.

Little is known about whether effectiveness of intimate partner violence prevention programming varies for women who were married as child brides, given their additional social vulnerabilities. This subanalysis sought to assess treatment heterogeneity based on child marriage status for an intervention seeking to reduce intimate partner violence. A randomized controlled trial assessing the incremental effectiveness of gender dialogue groups in addition to group savings on changing past-year intimate partner violence was conducted in Côte d'Ivoire (2010-2012). Stratified models were constructed based on child marriage status to assess for effect modification. Analysis was restricted to married women with data on age at marriage (n = 682). For child brides (N = 202), there were no statistically or marginally significant decreases in physical and/or sexual violence, physical violence, or sexual violence. The odds of reporting economic abuse in the past year were lower in the intervention arm for child brides relative to control group child brides (odds ratio [OR] = .33; 95% confidence interval [CI] = .13-.85; p = .02). For nonchild brides (N = 480), women were less likely to report physical and/or sexual violence (OR = .54; 95% CI = .28-1.04; p = .06), emotional violence (OR = .44; 95% CI = .25-.77; p = .004), and economic abuse (OR = .36; 95% CI = .20-.66; p = .001) in the combined intervention arm than their group savings-only counterparts. Findings suggest that intervention participants with a history of child marriage may have greater difficulty benefiting from interventions that seek to reduce intimate partner violence.

Background Burden of disease estimates are widely used for priority setting in public health and disability-adjusted life years are a powerful “currency” nowadays. However, disability weights, which capture the disability incurred by a typical patient of a certain condition, are fundamental to such burden calculation and their determination remains a widely debated issue. Methodology A cross-sectional epidemiological survey was conducted in the recently established Taabo health demographic surveillance system (HDSS) in south-central Côte d'Ivoire, to provide new, population-based evidence on the disability caused by schistosomiasis and soil-transmitted helminthiasis. Parasitological results from stool, urine, and blood examinations were juxtaposed to quality of life (QoL) questionnaire results from 187 adults. A multivariable linear regression model with stepwise backward elimination was used to identify significant associations, considering also sociodemographic characteristics obtained from the Taabo HDSS database. Principal Findings Prevalences for hookworm, Plasmodium spp., Trichuris trichiura, Schistosoma haematobium and Schistosoma mansoni were 39.0%, 18.2%, 2.7%, 2.1% and 2.1%, respectively. S. mansoni and T. trichiura infections of any intensity reduced the participants' self-rated QoL by 16 points (95% confidence interval (CI): 4–29 points) and 13 points (95% CI: 1–24 points), respectively, on a scale from 0 (worst QoL) to 100 points (best QoL). The only other statistically significant effect was a 1-point (95% CI: 0.1–2 points) increase on the QoL scale per one unit increase in a calculated wealth index. Conclusions/Significance We found consistent and significant results on the negative effects of schistosomiasis and soil-transmitted helminthiasis on adults' self-rated QoL, also when taking sociodemographic characteristics into account.

Full Text Available Landscapes Prospective Modeling of the landscapes of the Haut Sassandra Classified Forest (Côte d'Ivoire After the End of The Conflicts. It has been demonstrated that armed conflicts cause biodiversity's degradation, especially in its ecosystemic and specific dimensions. The Haut Sassandra Classified Forest is an interesting case study for this kind of process. Indeed, during the conflicts, a massive migrants infiltration caused a forest cover decline and a plant diversity loss. We created a multi-agent system able to simulate the actors' movements and behaviors. The social simulation generates scenario in the form of clearing maps in classified forest. This model was first conceived as a retro-prospective model in order to test hypotheses on the social dynamics underlying this process, after having worked on its accuracy by confronting reality. This model being validated, the aim of this paper is to present a prospective modeling to illustrate, in terms of forest cover's conservation, the possible consequences of different demographic and political scenarios. Across a geoprospective logic, two scenarios are mentioned such as the continuation of conflict period trends and a proposition of ecological restoration.

In August 2010, five positive cases of yellow fever were reported in the region of Séguéla, in the northwest of Côte d'Ivoire, affected by an armed conflict since 2002. In order to evaluate the extent of yellow fever virus circulation and the risk for local people, a multidisciplinary investigation was carried out by the Côte-d'Ivoire Ministry of Health and Public Hygiene. Theses investigations were conducted in the villages of confirmed cases and the outpatient and hospitalization centers attended by infected patients, two weeks after the reactive immunization campaign performed in order to stop the spread of the epidemic. The search for suspects identified 16 cases, including 4 cases and 2 deaths in hospital registers and 12 cases during community interviews, including 6 deaths. Stegomyiens indices were relatively low. Aedes aegypti was present among adult mosquitoes. In addition, three wild vectors, varying in number from one locality to another, were detected: Ae. africanus, Ae. luteocephalus and Ae. vittatus with average biting rates of 0.3; 0.1 and 0.05 bite/man/twilight, respectively, at Soba, Ae. africanus and Ae. vittatus with average biting rates of 0.25 and 0.3 bite/man/twilight, respectively, at Yaokro and Ae. luteocephalus with one bite/man/twilight at Kaborékro. Unfortunately, the vaccine response conducted before investigations did not stop progression of the epidemic which broke out three months later in the Worofla health area, close to the Magrékros encampment.

Full Text Available Cholera burden in Africa remains unknown, often because of weak national surveillance systems. We analyzed data from the African Cholera Surveillance Network (www.africhol.org.During June 2011-December 2013, we conducted enhanced surveillance in seven zones and four outbreak sites in Togo, the Democratic Republic of Congo (DRC, Guinea, Uganda, Mozambique and Cote d'Ivoire. All health facilities treating cholera cases were included. Cholera incidences were calculated using culture-confirmed cholera cases and culture-confirmed cholera cases corrected for lack of culture testing usually due to overwhelmed health systems and imperfect test sensitivity. Of 13,377 reported suspected cases, 34% occurred in Conakry, Guinea, 47% in Goma, DRC, and 19% in the remaining sites. From 0-40% of suspected cases were aged under five years and from 0.3-86% had rice water stools. Within surveillance zones, 0-37% of suspected cases had confirmed cholera compared to 27-38% during outbreaks. Annual confirmed incidence per 10,000 population was <0.5 in surveillance zones, except Goma where it was 4.6. Goma and Conakry had corrected incidences of 20.2 and 5.8 respectively, while the other zones a median of 0.3. During outbreaks, corrected incidence varied from 2.6 to 13.0. Case fatality ratios ranged from 0-10% (median, 1% by country.Across different African epidemiological contexts, substantial variation occurred in cholera incidence, age distribution, clinical presentation, culture confirmation, and testing frequency. These results can help guide preventive activities, including vaccine use.

Public health concerns of highly pathogenic avian influenza H5N1 endemicity in Africa

Full Text Available Highly pathogenic avian influenza virus (HPAIV H5N1 was first officially reported in Africa in 2006; thereafter this virus has spread rapidly from Nigeria to 11 other African countries. This study was aimed at utilizing data from confirmed laboratory reports to carry out a qualitative evaluation of the factors responsible for HPAI H5N1 persistence in Africa and the public health implications; and to suggest appropriate control measures. Relevant publications were sought from data banks and repositories of FAO, OIE, WHO, and Google scholars. Substantiated data on HPAI H5N1 outbreaks in poultry in Africa and in humans across the world were mined. HPAI H5N1 affects poultry and human populations, with Egypt having highest human cases (346 globally. Nigeria had a reinfection from 2014 to 2015, with outbreaks in Cote d'Ivoire, Ghana, Niger, Nigeria, and Burkina Faso throughout 2016 unabated. The persistence of this virus in Africa is attributed to the survivability of HPAIV, ability to evolve other subtypes through genetic reassortment, poor biosecurity compliance at the live bird markets and poultry farms, husbandry methods and multispecies livestock farming, poultry vaccinations, and continuous shedding of HPAIV, transboundary transmission of HPAIV through poultry trades; and transcontinental migratory birds. There is, therefore, the need for African nations to realistically reassess their status, through regular surveillance and be transparent with HPAI H5N1 outbreak data. Also, it is important to have an understanding of HPAIV migration dynamics which will be helpful in epidemiological modeling, disease prevention, control and eradication measures.

Introduction L'objectif de notre étude était de décrire les caractéristiques sociodémographiques et les Facteurs de Risque cardio-Vasculaires (FRV) des patients admis pour accidents vasculaires cérébraux (AVC) dans un service autre que celui de la neurologie. Méthodes Étude transversale rétrospective sur une période de 2 ans (janv. 2010 et déc. 2011), réalisée aux urgences de l'institut de cardiologie d'Abidjan. Résultats Il s'agissait de 176 adultes avec un âge moyen de 60 ans, une prédominance féminine. Les facteurs de risque majeurs retrouvés étaient l'hypertension artérielle dans 86,4% des cas, le diabète dans 11,4% des cas, le tabagisme dans 2,2% des cas. Les motifs de consultation étaient la perte de connaissance dans 36,4% des cas, l'hémiplégie dans 31,8% des cas, les céphalées dans 17,4% des cas, les vertiges dans 10,9% et les palpitations dans 2,2% des cas. La tension artérielle systolique moyenne était à 174 mmHg, la tension artérielle diastolique moyenne était à 105 mmHg et la pression pulsée moyenne était à 70 mmHg. Les AVC étaient associés à une arythmie complète par fibrillation auriculaire dans 11,4% des cas. Les AVC ischémiques représentaient 84,1%. L’évolution aux urgences a été marquée par un décès dans 17% (30) des cas. Conclusion Les AVC constituent un problème majeur de santé publique. Malgré sa prédominance féminine, ils (AVC) touchaient 44% des hommes dans notre étude lorsqu'on sait qu'en Afrique l'activité sociale repose sur les hommes. Ils restent une pathologie grave par la forte létalité. PMID:26327997

To assess whether implementation of a prevention of mother-to-child HIV transmission (PMTCT) programme in Côte d'Ivoire improved the quality of antenatal and delivery care services. Quality of antenatal and delivery care services was assessed in five urban health facilities before (2002-2003) and after (2005) the implementation of a PMTCT programme through review of facility data; observation of antenatal consultations (n = 606 before; n = 591 after) and deliveries (n = 229 before; n = 231 after) and exit interviews of women; and interviews of health facility staff. HIV testing was never proposed at baseline and was proposed to 63% of women at the first ANC visit after PMTCT implementation. The overall testing rate was 42% and 83% of tested HIV-infected pregnant women received nevirapine. In addition, inter-personal communication and confidentiality significantly improved in all health facilities. In the maternity ward, quality of obstetrical care at admission, delivery and post-partum care globally improved in all facilities after the implementation of the programme although some indicators remained poor, such as filling in the partograph directly during labour. Episiotomy rates among primiparous women dropped from 64% to 25% (P implementation. Global scores for quality of antenatal and delivery care significantly improved in all facilities after the implementation of the programme. Introducing comprehensive PMTCT services can improve the quality of antenatal and delivery care in general.

Full Text Available Feeding Diets of Ctenopoma petherici (Perciformes, Anabantidae from the Agneby River and from the Hydroelectric Lake Dam of Ayame 2 (Côte d'Ivoire. The present study describes the feeding habits of Ctenopoma petherici (Perciformes, Anabantidae in the Agneby River and in the hydroelectric Lake dam of Ayame 2. Fishes were caught monthly using gill-nets from September 2015 to August 2016. Stomach contents of 425 specimens were analysed under a magnifying glass and a microscope. The Relative Importance of Food Index has been calculated to assess the relative abundance of the preys. The general profile of the diet indicated that C. petherici feeds on insects, arachnids, molluscs, batrachians, macrophytes and algae. The insects provide the main part of the feeding and they constitute the principal prey category. Macrophytes were the secondary item while arachnids, molluscs, batrachians and algae were accessory preys. These results indicate that this species is omnivorous with an insectivorous tendency. This feeding pattern is seasonally affected, particularly in the Agneby River. However, there is no variation in the diet according to the size of the individuals.

Objectives Population-based HIV testing surveys have become central to deriving estimates of national HIV prevalence in sub-Saharan Africa. However, limited participation in these surveys can lead to selection bias. We control for selection bias in national HIV prevalence estimates using a novel approach, which unlike conventional imputation can account for selection on unobserved factors. Methods For 12 Demographic and Health Surveys conducted from 2001 to 2009 (N=138 300), we predict HIV status among those missing a valid HIV test with Heckman-type selection models, which allow for correlation between infection status and participation in survey HIV testing. We compare these estimates with conventional ones and introduce a simulation procedure that incorporates regression model parameter uncertainty into confidence intervals. Results Selection model point estimates of national HIV prevalence were greater than unadjusted estimates for 10 of 12 surveys for men and 11 of 12 surveys for women, and were also greater than the majority of estimates obtained from conventional imputation, with significantly higher HIV prevalence estimates for men in Cote d'Ivoire 2005, Mali 2006 and Zambia 2007. Accounting for selective non-participation yielded 95% confidence intervals around HIV prevalence estimates that are wider than those obtained with conventional imputation by an average factor of 4.5. Conclusions Our analysis indicates that national HIV prevalence estimates for many countries in sub-Saharan African are more uncertain than previously thought, and may be underestimated in several cases, underscoring the need for increasing participation in HIV surveys. Heckman-type selection models should be included in the set of tools used for routine estimation of HIV prevalence. PMID:23172342

Full Text Available L'érosion hydrique des sols n'a pas été suffisamment étudiée dans la région de Bonoua au Sud-Est de la Côte d'Ivoire où l'activité économique dominante demeure l'agriculture. Par conséquent, des méthodes de contrôle s'avèrent nécessaires, afin d'assurer une gestion durable des sols et de sécuriser les productions agricoles. L'objectif de cette étude est de fournir des éléments pour cartographier la vulnérabilité multifactorielle à l'érosion hydrique. L'approche passe par une analyse des principaux facteurs de l'érosion : l'érosivité des pluies, l'érodabilité des sols, la pente et l'occupation des sols. Les cartes obtenues sont intégrées dans un Système d'Information Géographique (SIG à l'aide d'une combinaison additive pour établir une carte de vulnérabilité à l'érosion hydrique. Cette carte est validée par des observations de terrain. Trois classes de vulnérabilité multifactorielle à l'érosion hydrique ont été distinguées : les zones à faible vulnérabilité (29 % ; les zones à vulnérabilité moyenne (34 % et les zones fortement vulnérables (37 %. Ainsi, dans la région de Bonoua, les classes à moyenne et forte vulnérabilité multifactorielle représentent 71 % de la superficie. Cette première ébauche cartographique est un outil devant aider les décideurs pour l'attribution des zones de cultures et des sites pouvant abriter des infrastructures socio-économiques.Water soils erosion has not been studied enough in the region of Bonoua south-eastern Côte d'Ivoire where major economic activity remains the agriculture.

Full Text Available Cocoa Expansion Dynamics in the Forest-Savanna Contact Zones: Case Study of the Sub-prefecture of Kokumbo (Côte d'Ivoire. In Ivory Coast, forests-savannah transition areas have been considered from the 1970s as unfavorable to cocoa cultivation. In recent years, however, there has been a comeback to the cocoa economy in these areas. This study carried out in the sub-prefecture of Kokumbo, aimed to map and to follows the spatial and temporal evolution of this crop using Landsat images of 1990, 2002 and 2016. In order to better understand the fundamentals of the peasant practices, surveys were carried out in different villages in the area. Treatment shows that the influence of cocoa culture is becoming increasingly important in the region. This cocoa crop is set up to the detriment of forests and savannahs, which have lost 25% and 58.1% of their initial area respectively. The surveys identified four types of cocoa farms, of which 65% of the plots were created between 2002 and 2014. Facing this relatively recent expansion, the issue of the sustainability of cocoa production systems in this region arises. Their agronomic and economic performances and their value for biodiversity conservation should be analyzed in future studies.

Hybrid power markets in Africa: Generation planning, procurement and contracting challenges

International Nuclear Information System (INIS)

2011-01-01

African power sectors are generally characterised by insufficient generation capacity. Reforms to address poor performances in the 1990s followed a prescribed evolution towards power markets that would allow wholesale competition amongst generators and so lead towards efficiency improvements. Despite reforms being embarked, competitive power markets have not been established in Africa; rather, the result has been the emergence of hybrid markets where state-owned generators and IPPs operate devoid of competition; and although IPPs have emerged in a number of African power sectors, many countries still do not have sufficient generation to meet their electricity demands. This paper investigates the development of private generation power projects in Africa by analysing data collected from both primary and secondary sources in four case studies of power sectors in Ghana, Cote d'Ivoire, Morocco and Tunisia. It identifies how planning and procurement challenges have lead to difficulties in adding sufficient generation capacity in a timely manner, exacerbating the problem of insufficient generation capacity in Africa. It provides suggestions as to how these frameworks could respond more effectively to the capacity challenges faced by hybrid electricity generation markets, and how broader power sector reforms should be guided to reflect the challenges of hybrid markets better. - Research highlights: → The standard model of power sector reform should no longer be used as a progress measure of power sector development in Africa and many other developing countries. → The hybrid market should in itself be recognised as an established 'model' of power sectors in Africa and many developing countries. → Planning, procurement and contracting arrangements should be shaped specifically for hybrid markets in order to address the problem of insufficient generation capacity in developing countries.

The rate of deforestation in Ghana is alarming and urgent steps need to be taken to reverse the trend, Robert D. Mann, a British tropical agriculturist, has warned. He says, "There will be further disintegration of the local climate, deterioration of soil fertility and reduced food-crop production, if the present trend of denudation by felling trees and uncontrolled bush fires is not halted and reversed." Mann, who has conducted research on "deforestation, drought and famine in Africa" was in Ghana recently to speak on the "role of the Church in West Africa in stimulating action to combat desertification". Representatives of protestant churches in Ghana, Togo, Liberia, Gambia, Nigeria, Cote d'Ivoire and Sierra Leone attended the 3-day conference which was organized by the Overseas Department of the British Methodist Church. It was to enable participants to share perspectives on the nature, scale and seriousness of the deforestation problem. Participants also exchanged experiences on village-based projects for promoting tree planting and agro-forestry, and developed strategies for the rural development programs. Robert Mann noted that Ghana was not only affected by its proximity to the Sahel, but also by its own deforestation. The situation in Ghana, once renowned for her extensive forests and woodland, has now drastically changed. By 1980/81 the area of closed forest had been reduced to 17,000 sq km from 47,9000 sq km in 1937/38. He said in 1939 the volume of wood exported from Ghana was 42,450 cubic meters but it rose to 1,471,600 cubic meters by 1987. Such activities, Mann said, put severe strain on the environment and affected both the economy and sociocultural basis of the country. full text

Tobacco smoking is a scourge that continues to increase in developing countries despite its known consequences. Is the population of the Ivory Coast sufficiently informed about the consequences of smoking? For this reason, we decided to evaluate the knowledge of the effects of smoking among the people of Abidjan. To evaluate the knowledge of the effects of smoking in the population of Abidjan. To relate this knowledge to the educational level and smoking status. We evaluated knowledge about smoking and its consequences as a function of educational level and smoking status in the population of Abidjan over the age of 15 years. This was undertaken in 3 months, from November 2005 to January 2006, in the two busiest communes in Abidjan. The minimum number of persons required was 1152 but, in fact, we interviewed 1409. The prevalence of smoking was 36.5% with a predominance of males (sex ratio = 3:11). They were mainly young with a mean age of 27.44 years. This population's main sources of information on the ill effects of smoking were the mass media. In general, the subjects did not have a good understanding of smoking and its consequences. With regard to the diseases related to smoking, bronchial carcinoma and cardiovascular disorders were the best known, in 53.1 and 18.1%, respectively. With regard to the components of tobacco, nicotine was the best known (92.6%). Knowledge was related to the level of education: the subjects of a higher educational level were the most knowledgeable about the consequences of smoking. As a result, these subjects were less attached to smoking than the less educated. The consequences of smoking are poorly understood by the general population. With regard to the level of education, the better educated had a better understanding of the effects of smoking and were also those who smoked the least. Copyright 2010.

Full Text Available BACKGROUND: Promising results have been reported for a urine circulating cathodic antigen (CCA test for the diagnosis of Schistosoma mansoni. We assessed the accuracy of a commercially available CCA cassette test (designated CCA-A and an experimental formulation (CCA-B for S. mansoni diagnosis. METHODOLOGY: We conducted a cross-sectional survey in three settings of Côte d'Ivoire: settings A and B are endemic for S. mansoni, whereas S. haematobium co-exists in setting C. Overall, 446 children, aged 8-12 years, submitted multiple stool and urine samples. For S. mansoni diagnosis, stool samples were examined with triplicate Kato-Katz, whereas urine samples were tested with CCA-A. The first stool and urine samples were additionally subjected to an ether-concentration technique and CCA-B, respectively. Urine samples were examined for S. haematobium using a filtration method, and for microhematuria using Hemastix dipsticks. PRINCIPAL FINDINGS: Considering nine Kato-Katz as diagnostic 'gold' standard, the prevalence of S. mansoni in setting A, B and C was 32.9%, 53.1% and 91.8%, respectively. The sensitivity of triplicate Kato-Katz from the first stool and a single CCA-A test was 47.9% and 56.3% (setting A, 73.9% and 69.6% (setting B, and 94.2% and 89.6% (setting C. The respective sensitivity of a single CCA-B was 10.4%, 29.9% and 75.0%. The ether-concentration technique showed a low sensitivity for S. mansoni diagnosis (8.3-41.0%. The specificity of CCA-A was moderate (76.9-84.2%; CCA-B was high (96.7-100%. The likelihood of a CCA-A color reaction increased with higher S. mansoni fecal egg counts (odds ratio: 1.07, p<0.001. A concurrent S. haematobium infection or the presence of microhematuria did not influence the CCA-A test results for S. mansoni diagnosis. CONCLUSION/SIGNIFICANCE: CCA-A showed similar sensitivity than triplicate Kato-Katz for S. mansoni diagnosis with no cross-reactivity to S. haematobium and microhematuria. The low sensitivity

Introduction: Victorian Theatricalities

Full Text Available After a barrage of manipulative fan-letters from Sir Merton and Annie Russell-Cotes, Sir Henry Irving, titan of the Victorian stage and the first actor to be knighted, eventually came to stay, briefly, at East Cliff Hall in Bournemouth. A peculiar but attractive compound of Scots baronial castle, Italian villa, French château and Bournemouth seaside bungalow, complete with lavish Art Nouveau interiors and a fountain in the entrance lobby, the house was always designed in and of itself as a dramatic location and was also intended as a magnet for theatrical celebrities. Sir Merton and Annie amply stuffed it with nineteenth-century British paintings, miscellaneous sculptures, and souvenirs of their extensive overseas holidays. Today the Russell-Cotes Art Gallery and Museum remains the late Victorian treasure house par excellence, and I can imagine few more vivid short-cuts into the culture and mindset of the late nineteenth-century haute bourgeoisie than an afternoon spent marvelling at the tons of accumulated trophies and bibelots cluttering its rooms or the acres of tastefully-exposed nipples adorning its walls. What the Russell-Cotes Museum also makes clear, even at its gloomiest, is the key place of drama in the Victorian imagination. After Irving's death in 1905, the Russell-Cotes bought many of Irving's personal effects at auction. Adding these to their existing collection of Irving memorabilia and other theatrical paintings and souvenirs, they converted the bedroom in which Irving had stayed into a permanent shrine to his memory. The Henry Irving Room would make an ideal introduction to most of the contents of this volume.

Full Text Available Integrated control programs, emphasizing preventive chemotherapy along with health education, can reduce the incidence of soil-transmitted helminthiasis and schistosomiasis. The aim of this study was to develop an educational animated cartoon to improve school children's awareness regarding soil-transmitted helminthiasis, diarrheal diseases, and related hygiene practices in Côte d'Ivoire. The key messages included in the cartoon were identified through prior formative research to specifically address local knowledge gaps.In a first step, preliminary research was conducted to assess the knowledge, attitudes, practices, and beliefs of school-aged children regarding parasitic worm infections and hygiene, to identify key health messages to be included in an animated cartoon. Second, an animated cartoon was produced, which included the drafting of the script and story board, and the production of the cartoon's initial version. Finally, the animated cartoon was pilot tested in eight selected schools and further fine-tuned.According to the questionnaire results, children believed that the consumption of sweet food, eating without washing their hands, sitting on the floor, and eating spoiled food were the main causes of parasitic worm infections. Abdominal pain, diarrhea, lack of appetite, failure to grow, and general fatigue were mentioned as symptoms of parasitic worm infections. Most of the children knew that they should go to the hospital for treatment if they experienced symptoms of parasitic worm diseases.

Water is an essential element of life, but it can also be a source of disease. Apart from direct consumption of unsafe water, direct contact and indirect consumption puts people at risk of many different types of pathogens. Employing a mixed methods approach, consisting of questionnaires and direct observations, we assessed access to, and use of, different water sources by the participants of the district des Savanes in northern Côte d'Ivoire. The use of water sources was put in relation to the potential risk of acquiring schistosomiasis and fascioliasis. Overall, 489 people aged 8 to 82 years participated. While all participants had access to safe water, 63% were in direct contact with unimproved water and 31% directly consumed unsafe water. More than a third of the people who otherwise reported using only improved water for all activities came in contact with unimproved water through crossing open water when going to their workplace, school or other destinations. Self-reported blood in urine - a marker for Schistosoma haematobium with reasonable sensitivity and specificity - was reported by 6% (n=30), self-reported blood in stool - an unspecific marker for Schistosoma mansoni - was reported by 7% (n=35), while blood co-occurring in both urine and stool was reported by another 10% (n=48) of participants. Accessing unimproved water for any activity (including crossing) was associated with higher odds of reporting blood in urine and/or blood in stool (odds ratio: 1.90; 95% confidence interval: 1.07-3.36). Our results have important rami-fications for intervention programmes targeting neglected tropical diseases, and emphasize the need for a wider supply of safe water to rural populations, since the water supply at the workplace needs to be considered as well next to the water supply at home. Crossing of open water sources is an important risk factor for sustained transmission of schistosomiasis. Copyright © 2015 Elsevier B.V. All rights reserved.

Temporal trends in treatment outcomes for HIV-1 and HIV-2-infected adults enrolled in Côte d'Ivoire's national antiretroviral therapy program.

Full Text Available In Côte d'Ivoire during 2004-2007, numbers of ART enrollees increased from <5,000 to 36,943. Trends in nationally representative ART program outcomes have not yet been reported.We conducted a retrospective chart review to assess trends in patient characteristics and attrition [death or loss to follow-up (LTFU] over time, among a nationally representative sample of 3,682 adults (≥15 years initiating ART during 2004-2007 at 34 health facilities. Among ART enrollees during 2004-2007, median age was 36, the proportion female was 67%, the proportion HIV-2-infected or dually HIV-1&2 reactive was 5%, and median baseline CD4+ T-cell (CD4 count was 135 cells/µL. Comparing cohorts initiating ART in 2004 with cohorts initiating ART in 2007, median baseline weight declined from 55 kg to 52 kg (p = 0.008 and the proportion weighing <45 kg increased from 17% to 22% (p = 0.014. During 2004-2007, pharmacy-based estimates of the percentage of new ART enrollees ≥95% adherent to ART declined from 74% to 60% (p = 0.026, and twelve-month retention declined from 86% to 69%, due to increases in 12-month mortality from 2%-4% and LTFU from 12%-28%. In univariate analysis, year of ART initiation was associated with increasing rates of both LTFU and mortality. Controlling for baseline CD4, weight, adherence, and other risk factors, year of ART initiation was still strongly associated with LTFU but not mortality. In multivariate analysis, weight <45 kg and adherence <95% remained strong predictors of LTFU and mortality.During 2004-2007, increasing prevalence among ART enrollees of measured mortality risk factors, including weight <45 kg and ART adherence <95%, might explain increases in mortality over time. However, the association between later calendar year and increasing LTFU is not explained by risk factors evaluated in this analysis. Undocumented transfers, political instability, and patient dissatisfaction with crowded facilities might explain

Given the broad commercial applications for ZnO nanomaterials, accurate attribution of physicochemical characteristics that induce toxic effects is particularly important. We report on the physicochemical properties of three commercial nano-ZnO products: Z-COTE and Z-COTE HP1 from BASF, and Nanosun from Micronisers, and, for reference, “bulk” ZnO from Sigma-Aldrich. Z-COTE, Nanosun and “bulk” consist of uncoated particles with different sizes, while Z-COTE HP1 consists of nanoparticles with a hydrophobic coating. Specific batches of these ZnO products were included in the OECD Sponsorship Programme to test manufactured nanomaterials. In order to identify properties potentially susceptible to variations between production runs, three additional batches of Z-COTE and Nanosun and two additional batches of Z-COTE HP1 were also investigated here. In general, all products showed little variation between batches for properties measured from powdered samples, but batch variations in the amount of surface coating were evident for the coated Z-COTE HP1. Properties measured with samples dispersed in liquids (agglomeration, photocatalytic activity, dissolution) were highly dependent on dispersion protocols, and this made it difficult to differentiate between differences due to dispersion and due to batches. However, batch-sensitive properties did appear to be present in Z-COTE and Z-COTE HP1 (photocatalytic activity), and Nanosun (dissolution). Intra-batch time and/or storage-dependent changes in the applied surface coating, noted specifically for the OECD batch of Z-COTE HP1, highlight the need for best practice when storing and accessing stocks of nano products. Awareness of inter-batch and intra-batch variability is essential for commercial applications and for nanotoxicological studies aimed at identifying links between physicochemical properties and any adverse effects in biological systems.

We investigate the electronic structures and stability for Ni/Bi 2 Te 3 , NiTe/Bi 2 Te 3 , Co/Bi 2 Te 3 and CoTe 2 /Bi 2 Te 3 interfaces by first-principles calculations. It is found that the surface termination strongly affects the band alignment. Ni and Co are found to form Ohmic contacts to Bi 2 Te 3 . The interface formation energy for Co/Bi 2 Te 3 interfaces is much lower than that of Ni/Bi 2 Te 3 interfaces. Furthermore, we found that NiTe on Bi 2 Te 3 is more stable than Ni, while the formation energies for Co and CoTe 2 on Bi 2 Te 3 are comparable.

Snail-borne trematodiases, such as fascioliasis and schistosomiasis, belong to the neglected tropical diseases; yet, millions of people and livestock are affected. The spatial and temporal distribution of intermediate host snails plays an important role in the epidemiology and control of trematodiases. Snail distribution is influenced by numerous environmental and anthropomorphic factors. The aim of this study was to assess the distribution and constitution of the snail fauna during the dry season in constructed and natural water bodies in the Tchologo region, northern Côte d'Ivoire, and to relate these findings to environmental factors and human infections. Snails were collected using standard procedures and environmental parameters were assessed from a total of 50 water bodies in and around 30 randomly selected villages. A canonical correspondence analysis was performed to establish the relationship between snail occurrence and environmental factors. Furthermore, a total of 743 people from the same 30 villages and nearby settlements were invited for stool and urine examination for the diagnosis of Fasciola spp., Schistosoma haematobium and Schistosoma mansoni. Snails of medical importance of the genera Biomphalaria, Bulinus, Lymnaea and Physa were found. Differences in snail occurrence from sites sampled in December 2014 and snails sampled in February 2015, as well as between the northern and southern part of the study area, were revealed. Various environmental factors, such as temperature and human activities, were related to the occurrence of intermediate host snail species in the region. Only 2.3% of human participants tested positive for schistosomiasis, while no Fasciola eggs were found in stool samples. We conclude that intermediate host snails of Fasciola and Schistosoma co-occur in water bodies in the Tchologo region and that the distribution of these snails correlates not only with environmental factors, but also with the presence of humans and animals

The incomes of the producers of cocoa are decreasing. Because of the great impact of the cocoa production on farm land, the available area to fulfill the food needs becomes insufficient. Forty three percent of the households lack sufficient land to satisfy their food production. The minimum period of seven year of fallow being no longer respected soil fertility problems are created and consequently a decrease of the agricultural yields. Fifty seven percent of the households are facing food insecurity. Therefore, the households have elaborated new strategies for land appropriation, such as the borrowing of farm land (13 %, the increased use of the phytosanitary products (52% and particularly the higher attraction for the exploitation of fallow land (40%.

Tsetse flies, biodiversity and the control of sleeping sickness. Structure of a Glossina guild in southwest Côte d'Ivoire

Science.gov (United States)

Gouteux, Jean-Paul; Jarry, Marc

1998-10-01

Tsetse fly guilds usually comprise two or three species. However, the presence of only one species often indicates that anthropic modifications have occurred in the habitat. On the other hand, more than three species are seldom observed in the same zone and the presence of five is extremely rare. Previous detailed studies have always focused on a single species, without taking into account interactions between species. The authors present the results of observations carried out in Côte d'Ivoire on a guild consisting of Glossina palpalis, G. pallicera, G. nigrofusca, G. longipalpis and G. fusca. Glossina have unusual physiological characteristics: both sexes feed exclusively on blood, they have a highly developed larviparity associated with a slow rhythm of reproduction (one larva about every ten days) and a long life expectancy (up to nine months). The authors report on the size of the flies, the hosts, feeding habits, ecodistribution, resting-places, flying heights, circadian activity and seasonal dynamics of tsetse fly populations in order to understand the organization of this guild. Each species feeds indiscriminately on a wide spectrum of hosts without a particular preference. Different species shared habitat (ecodistribution) and time (circadian and annual cycles). Thus, during an annual cycle, there is always a slight time-lag between the density peaks of G. palpalis and G. pallicera, the peak of the dominant species immediately preceding that of the dominated species. In a village area, 77% of the variations in density of G. pallicera were accounted for by the previous variations in density of the dominant species ( G. palpalis). Experiments show that G. pallicera and G. nigrofusca immediately invade anthropic areas from which G. palpalis has been partially removed by trapping. These species thus appear to confront each other in a global dynamic equilibrium. This suggests that there is a 'conflicting coexistence' between the cohabiting species. Whereas the

Kerkhoven, R

1998-02-01

By the end of 1997, an estimated 20.8 million people in sub-Saharan Africa were infected with HIV, 68% of all HIV infections. At the Tenth Annual International Conference on STDs and AIDS in Africa held in Abidjan in 1997, the MAP network continued its series of pre-conference symposia on the shape and status of HIV/AIDS in the various continents. The outcome of the Abidjan symposium was then published in a provisional report made available to the main conference's participants. The main conclusions of the symposium with regard to the following areas and subjects are presented: West Africa, Central Africa, the Horn of Africa, Eastern Africa, Southern Africa, life expectancy, HIV/AIDS and STDs, data, determinants of the spread of HIV, the relative importance of determinants, poverty, understanding determinants, the national response, children and the spread of HIV, and the future.

Vector control can contribute to the development of resistance to insecticides in malaria vectors. As the swamps and wetlands used for some agricultural activities constitute productive breeding sites for many mosquito species, agricultural pest control may increase the selection pressure for insecticide resistance in mosquitoes. Understanding the use of agrochemicals by farmers is important to plan and initiate effective integrated pest and vector management interventions. A knowledge-attitude-practice study, using questionnaires, was undertaken with 102 rice farmers in Tiassalé and 106 vegetable farmers in Dabou (South Côte d'Ivoire) in order to generate information on pesticide usage. In addition, insecticide susceptibility bioassays were conducted using adult mosquitoes obtained from larvae collected within farms, and the persistence of agricultural pesticides in the farming environment, including sediment and mosquito breeding site water, was investigated by HPLC. Herbicides and insecticides appeared to be the most frequently used pesticides for both crops. Amino phosphonates (mostly glyphosate) represented the most used herbicides (45 % for rice up to 89 % for vegetables). Pyrethroids appeared to be the most used insecticides (accounting for 90 % of all the insecticide use reported). Approximately 75 % of respondents had not been to school and do not understand product labels. Only about 45 % of farmers respect the recommended pesticide dosage and about 10-15 % of pesticides used for rice and vegetable, respectively, are not recommended for these crops. As per WHO criteria, the mosquito local populations from the two localities were resistant to three of the four insecticides tested, as mortalities were less than 35 % for deltamethrin, DDT and bendiocarb. Higher susceptibility was observed for malathion, although the population was considered resistant in Dabou (80 % mortality) and susceptible in Tiassalé (98 % mortality). With the exception of

Effect of an armed conflict on relative socioeconomic position of rural households: case study from western Côte d'Ivoire

Directory of Open Access Journals (Sweden)

Fürst Thomas

2010-08-01

Full Text Available Abstract Background Current conceptual frameworks on the interrelationship between armed conflict and poverty are based primarily on aggregated macro-level data and/or qualitative evidence and usually focus on adherents of warring factions. In contrast, there is a paucity of quantitative studies about the socioeconomic consequences of armed conflict at the micro-level, i.e., noncommitted local households and civilians. Methods We conducted a secondary analysis of data pertaining to risk factors for malaria and neglected tropical diseases. Standardized questionnaires were administered to 182 households in a rural part of western Côte d'Ivoire in August 2002 and again in early 2004. Between the two surveys, the area was subject to intensive fighting in the Ivorian civil war. Principal component analysis was applied at the two time points for constructing an asset-based wealth-index and categorizing the households in wealth quintiles. Based on quintile changes, the households were labeled as 'worse-off', 'even' or 'better-off'. Statistical analysis tested for significant associations between the socioeconomic fates of households and head of household characteristics, household composition, village characteristics and self-reported events associated with the armed conflict. Most-poor/least-poor ratios and concentration indices were calculated to assess equity changes in households' asset possession. Results Of 203 households initially included in the first survey, 21 were lost to follow-up. The population in the remaining 182 households shrunk from 1,749 to 1,625 persons due to migration and natural population changes. However, only weak socioeconomic dynamics were observed; every seventh household was defined as 'worse-off' or 'better-off' despite the war-time circumstances. Analysis of other reported demographic and economic characteristics did not clearly identify more or less resilient households, and only subtle equity shifts were noted

Antimicrobial resistance genes can be found in all ecosystems, including those where antibiotic selective pressure has never been exerted. We investigated resistance genes in a collection of faecal samples of wildlife (non-human primates, mice), people and domestic animals (dogs, cats) in Côte d'Ivoire; in the chimpanzee research area of Taï National Park (TNP) and adjacent villages. Single bacteria isolates were collected from antibiotic-containing agar plates and subjected to molecular analysis to detect Enterobacteriaceae isolates with plasmid-mediated genes of extended-spectrum beta-lactamases (ESBLs) and plasmid-mediated quinolone resistance (PMQR). While the prevalence of ESBL-producing E. coli in the villages was 27% in people (n = 77) and 32% in dogs (n = 38), no ESBL-producer was found in wildlife of TNP (n = 75). PMQR genes, mainly represented by qnrS1, were also present in human- and dog-originating isolates from the villages (36% and 42% in people and dogs, respectively), but no qnrS has been found in the park. In TNP, different variants of qnrB were detected in Citrobacter freundii isolates originating non-human primates and mice. In conclusion, ESBL and PMQR genes frequently found in humans and domestic animals in the villages were rather exceptional in wildlife living in the protected area. Although people enter the park, the strict biosecurity levels they are obliged to follow probably impede transmission of bacteria between them and wildlife.

The use of insecticide-treated nets for reducing malaria morbidity among children aged 6-59 months, in an area of high malaria transmission in central Côte d'Ivoire

Directory of Open Access Journals (Sweden)

Nsanzabana Christian

2010-09-01

Full Text Available Abstract Background Long-lasting insecticidal nets (LLINs are an important tool for controlling malaria. Much attention has been devoted to determine both the effect of LLINs on the reduction of Plasmodium infection rate and on clinically-confirmed malaria cases in sub-Saharan Africa. We carried out an epidemiological study to investigate whether LLINs impact on Plasmodium prevalence rate and the proportion of clinically-confirmed malaria cases, in five villages in the district of Toumodi, central Côte d'Ivoire. Methods From April 2007 to November 2008, a community-based malaria control programme was implemented in the study villages, which involved large-scale distribution of LLINs, and training and sensitization activities within the community. We determined the effect of this programme on Plasmodium prevalence rate, clinically-confirmed malaria cases and proportion of high parasitaemia rates in children aged 6-59 months through a series of cross-sectional surveys starting in April 2007 and repeated once every 6 months. Results We observed a significant decrease in the mean P. falciparum prevalence rate from April 2007 to April 2008 (p = 0.029. An opposite trend was observed from November 2007 to November 2008 when P. falciparum prevalence rate increased significantly (p = 0.003. Highly significant decreases in the proportions of clinical malaria cases were observed between April 2007 and April 2008 (p Conclusions Large-scale distribution of LLINs, accompanied by training and sensitization activities, significantly reduced Plasmodium prevalence rates among young children in the first year of the project, whereas overall clinical malaria rates dropped over the entire 18-month project period. A decrease in community motivation to sleep under bed nets, perhaps along with changing patterns of malaria transmission, might explain the observed increase in the Plasmodium prevalence rate between November 2007 and November 2008.

The efficacy of permethrin-treated Olyset Net mosquito nets on malaria transmission and morbidity was studied in Kafine, a village located in the savanna region of the Cote d'Ivoire in Africa. After collecting sociodemographic, entomological, and parasitological data, bednets were distributed first in the southern half of the village and then in the whole village. Throughout the study period, mosquito specimens were captured on the skin of inhabitants at four points in the village between 6 PM and 6 AM both inside (but outside bednets) and outside houses. Prior to distribution of bednets, the mean biting rate (MBR) by Anopheles gambiae was 77.4 bites per man per night (b/m/n). The mean parturity rate (MPR) was 40.6 p. 100, the sporozootic index (SI) was 0.99 p. 100, and the mean entomological inoculation rate (MEIR) was 0.7 infectious bites per man per night (b+/m/n). Six months after distribution of bednets in the southern half of the village, MBR was 80.2 b/m/n, MPR was 32 p. 100, SI was 1.8 p. 100, and MEIR was 0.83 b+/m/n. After extending distribution to the whole village, data from November 1996 to July 1997 were as follows: MBR, 67.8 b/m/n; MPR, 20.1 p. 100; SI, 0.65 p. 100; and MEIR, 0.66 p. 100. From August 1977 to July 1998, data were as follows: MBR, 102.6 b/m/n; MPR, 26.2 p. 100; SI, 1.15 p. 100; and MEIR, 0.74 b+/m/n. Comparative analysis of these data showed that use of bednets had no effect on the bite or entomological inoculation rate. This is in agreement with the documented resistance of vectors in the study zone to permethrin. Despite the known stimulation/repulsion effect of permethrin, use of treated bednets had no real impact on transmission. This inefficacy could be related to the high prevalence (80 p. 100) of the Kdr gene (responsible for resistance) in the savanna form of Anopheles gambiae.

Yellow fever vaccine: an effective vaccine for travelers.

Yellow fever (YF) is an acute viral communicable disease transmitted by an arbovirus of the Flavivirus genus. It is primarily a zoonotic disease, especially the monkeys. Worldwide, an estimated 200,000 cases of yellow fever occurred each year, and the case-fatality rate is ~15%. Forty-five endemic countries in Africa and Latin America, with a population of close to 1 billion, are at risk. Up to 50% of severely affected persons from YF die without treatment. During 2009, 55 cases and 18 deaths were reported from Brazil, Colombia, and Peru. Brazil reported the maximum number of cases and death, i.e., 42 cases with 11 deaths. From January 2010 to March 2011, outbreaks of YF were reported to the WHO by Cameroon, Democratic Republic of Congo, Cote d'Ivoire, Guinea, Sierra Leone, Senegal, and Uganda. Cases were also reported in three northern districts of Abim, Agago, and Kitugun near the border with South Sudan. YF usually causes fever, muscle pain with prominent backache, headache, shivers, loss of appetite, and nausea or vomiting. Most patients improve, and their symptoms disappear after 3 to 4 d. Half of the patients who enter the toxic phase die within 10-14 d, while the rest recover without significant organ damage. Vaccination has been the single most important measure for preventing YF. The 17D-204 YF vaccine is a freeze-dried, live attenuated, highly effective vaccine. It is available in single-dose or multi-dose vials and should be stored at 2-8 °C. It is reconstituted with normal saline and should be used within 1 h of reconstitution. The 0.5 mL dose is delivered subcutaneously. Revaccination is recommended every 10 y for people at continued risk of exposure to yellow fever virus (YFV). This vaccine is available worldwide. Travelers, especially to Africa or Latin America from Asia, must have a certificate documenting YF vaccination, which is required by certain countries for entry under the International Health Regulations (IHR) of the WHO.

Full Text Available The millennium development goals are now replaced by seventeen sustainable development goals. The emphasis of old goals was on improving water, sanitation, and child mortality conditions in developing countries. The study explored the major question about the association between different household environment conditions with child survival and health in Sub-Saharan African and South Asian countries in the current scenario. This paper estimated the risk of death, morbidity and under-nutrition among children living in households with the improved sources of water, sanitation and non-solid cooking fuel. Two sources of information explored in this study. First, data from World Health Statistics (WHS -2014 for all of the Sub-Saharan African and South Asian countries were used. Second, available standard Demographic and Health Survey performed in the countries of Sub-Saharan Africa and South Asia after 2010, included in the study. It resulted in inclusion of 15 countries which were Bangladesh (2011, Congo Republic (2013-14, Cote d'Ivoire (2011-12, Ethiopia (2011, Gambia (2013, Mali (2012-13, Mozambique (2011, Namibia (2013, Nepal (2011, Niger (2012, Nigeria (2013, Pakistan (2012-13, Sierra Leone (2013, Uganda (2011 and Zambia (2013. The Scatter plot diagram was plotted, and the curve was fitted using the WHS-2014. Cox regression and logistic regression were used to estimate adjusted risks (odds ratio of child mortality and health outcomes using DHS surveys. The use of non-solid cooking fuel was very high in most of the Sub-Saharan African and South Asian Countries. There was a positive correlation between improving access to safe drinking water and sanitation. The exponential curve fitted well with child mortality and Household environmental indicators. The use of improved source of water and sanitation significantly related with the lower odds ratio of death, morbidity and under-nutrition among children aged 12-59 months. The risks were not

The topical steroids betamethasone (BM) and clobetasol propionate (CP) are illegal in cosmetics. Hydroquinone (HQ) and mercury (Hg) are either illegal or allowed only in limited concentrations (2% and 1 ppm, respectively). To investigate active ingredients and countries of origin of popular skin-lightening products available in Cape Town, South Africa. In total, 29 products were examined; of these, 22 products were purchased from informal vendors, and 2 products (out of a total of 29) were purchased over the counter. HQ, Hg(2+) and steroids were quantified by high-performance liquid chromatography-ultraviolet spectrophotometry, inductively coupled plasma-mass spectrometry and liquid chromatography-mass spectrometry, respectively. Of the 29 products, 22 (75.9%), all imported and bought from informal vendors, contained illegal or banned ingredients: 13 (44.8%) contained steroids (9 CP, 4 BM), 12 (41.4%) contained Hg (30-2300 ppm), and 11 (37.9%) contained HQ. Sequentially, the products originated from Italy (27.3%, n = 6), India (22.7%, n = 5), the Democratic Republic of Congo (DRC) (22.7%, n = 5), Cote d'Ivoire (9.1%, n = 2), USA (9.1%, n = 2), UK (4.5%, n = 1) and France (4.5%, n = 1). Two products, one from India and one from the DRC, contained all four ingredients (HQ, Hg, BM, CP). Of the 12 products containing Hg, 10 also contained HQ and/or a steroid, yet none listed Hg as an ingredient. A significant proportion of the steroid-containing products (76.9%) also contained at least one other skin-lightening agent. Not all internationally available products were tested, which is a limitation of the study. In spite of a European Union ban on skin lighteners, a third of the products tested were from Europe. Combinations of Hg and ultrapotent steroids were prominent. International law enforcement and random testing is needed to encourage industry compliance and help protect consumers. © 2015 British Association of Dermatologists.

Geology and total petroleum systems of the Gulf of Guinea province of West Africa

Science.gov (United States)

Brownfield, Michael E.; Charpentier, Ronald R.

2006-01-01

The Gulf of Guinea Province as defined by the U.S. Geological Survey (USGS) consists of the coastal and offshore areas of Cote d'Ivoire, Ghana, Togo, and Benin, and the western part of the coast of Nigeria, from the Liberian border east to the west edge of the Niger Delta. The province includes the Ivory Coast, Tano, Central, Saltpond, Keta, and Benin Basins and the Dahomey Embayment. The area has had relatively little hydrocarbon exploration since 1968, with only 33 small to moderate-sized oil and gas fields having been discovered prior to the USGS assessment. Most discoveries to 1995 have been located in water depths less than 500 m. Since 1995, only eight new offshore discoveries have been made, with four of the discoveries in the deep-water area of the province. Although as many as five total petroleum systems exist in the Gulf of Guinea Province, only one, the Cretaceous Composite Total Petroleum System, and its assessment unit, the Coastal Plain and Offshore Assessment Unit, had sufficient data to allow assessment. The province shows two important differences compared to the passive-margin basins south of the Niger Delta: (1) the influence of transform tectonics, and (2) the absence of evaporites and salt deformation. The province also lacks long-lived, large deltaic systems that typically result in rapid source rock burial and abundant high-quality hydrocarbon reservoirs. The USGS assessed the potential for undiscovered conventional oil and gas resources in the Gulf of Guinea Province as part of its World Petroleum Assessment 2000, estimating a mean of 1,004 million barrels of conventional undiscovered oil, 10,071 billion cubic feet of gas, and 282 million barrels of natural gas liquids. Most of the hydrocarbon potential is postulated to be in the offshore, deeper waters of the province. Gas resources may be large, as well as accessible, in areas where the zone of hydrocarbon generation is relatively shallow.

Multiscale analysis of deforestation risk due to commodity crop expansion in sub-Saharan Africa and the role of non-industrial producers

Ordway, E.; Asner, G. P.; Naylor, R. L.; Nkongho, R.; Lambin, E.

Rapid integration of global agricultural markets and subsequent cropland displacement in recent decades increased large-scale tropical deforestation in South America and Southeast Asia. Growing land scarcity and more stringent land use regulations in these regions could incentivize the offshoring of export-oriented commodity crop production to sub-Saharan Africa (SSA). We assess the effects of domestic- and export-oriented agricultural expansion on deforestation in SSA in recent decades at the global, regional and local scales. Using Cameroon as a case-study, we explore the influence of emerging oil palm expansion on deforestation in greater depth. We found that commodity crops are expanding in SSA, increasing pressure on tropical forests. Four Congo Basin countries, Sierra Leone, Liberia, and Cote d'Ivoire were most at risk in terms of exposure, vulnerability and pressures from agricultural expansion. These countries averaged the highest percent forest cover (58% ±17.9) and lowest proportions of potentially available cropland outside forest areas (1% ±0.9). Foreign investment in these countries was concentrated in oil palm production (81%), with a median investment area of 41,582 thousand ha. Based on remote sensing and field survey results, however, medium- and large-scale non-industrial producers are driving a substantial fraction of the oil palm expansion leading to deforestation in Cameroon. Additionally, unlike Southeast Asia, oil palm expansion in sub-Saharan Africa is associated primarily with domestic market demands. In contrast, cocoa, the fastest expanding export-oriented crop across SSA, accounted for 57% of global expansion in 2000-2013 at a rate of 132 thousand ha yr-1, yet only amounted to 0.9% of foreign land investment. Commodity crop expansion in SSA appears largely driven by small- and medium-scale farmers rather than industrial plantations. Findings highlight that, although most agricultural expansion was associated with domestic demand, there

2017-03-01

Full Text Available As the world’s third-largest cocoa beans producer, Indonesia is expected to have a comparative advantage and to become cocoa beans price reference. This research investigates market power of Indonesia cocoa beans export for the United State market as an impact of an export tax. Five cocoa beans exporting countries namely Cote d’Ivoire, Ecuador, Ghana, Dominica Rep and Nigeria are calculated their market power as Indonesia’s competitors by estimating residual demand elasticity with two stage least square method. The results show that Indonesia’s market power suffered after imposing the export tax. Cote d’Ivoire and Ghana get advantages from this export restriction. The effect of export tax on welfare is analyzed by calculating terms of trade. The gain from cocoa beans trade depicts a declining terms of trade for dealing with the international cocoa beans market.

Determination of stable and radioactive isotopes in rain water for the equatorial and Sahel zones

Baudet, J.; Lesne, H.

1975-01-01

The extension of desert zones to detriment of Sahel zones lead to look for the circuit followed by water vapor between its principal source, i.e. the Guinea Gulf, and the place where it is changed in precipitation. Samples of rainwater have been collected in Abidjan, Ouagadougou, and Niamey when the Intertropical Front was beginning its moving down towards the South, i.e. at the end of the rainy season for the Sahel zone, and at the beginning of the small rainy season for the equatorial zone. The analysis of these tritium, deuterium and oxygen-18 contents show that: the rains collected in Abidjan comes mainly from Ocean; the rains collected in Ouagadougou and Niamey have followed a long journey above the continent, as shown by the tritium content. The water evaporated in the Guinea Gulf is condensed in the convergence zone above Cameroon, and mixed with re-evaporated continental water. The content of one of the Ouagadougou sample shows that the rain issued from a local cumulonimbus has drawn a part of its water from the stratosphere [fr

Oil spill contingency planning in the Ivory coast

Bender, K.; Jensen, S.K.; Ostergaerd, J.; Nogbou, P.

1993-01-01

The administrative center in charge of handling oil spill pollution situations on the Ivory Coast, West Africa, is named Centre Ivoirien Antipollution (CIAPOL). Its organizational structure has been reshuffled recently. CIAPOL now has three divisions: a laboratory division, a division for cleaning up oil and chemical pollution at sea, and an administrative division. The risk for oil pollution is known: within the past ten years five spills have been reported. All of these have been connected to operations relating to the refinery in Abidjan. More than 2,000 ships call at the port of Abidjan every year. Minor oil slicks are found almost permanently in the harbor and the lagoons around the harbor. Lumps of tar are rather common on the beaches all along the country's coast. This paper focuses on the background investigation in sensitive areas and risk analysis that led to a revision of the oil spill contingency plan, Plan Pollumar, and the recent purchase of oil spill cleanup equipment. The creation of a regional oil pollution response center at CIAPOL for all of the countries in West Africa, is proposed

As part of the Dynamics-Aerosol-Chemistry-Cloud Interactions in West Africa (DACCIWA) project, an airborne campaign was designed to measure a large range of atmospheric constituents, focusing on the effect of anthropogenic emissions on regional climate. The presented study details results of the French ATR42 research aircraft, which aimed to characterize gas-phase, aerosol and cloud properties in the region during the field campaign carried out in June/July 2016 in combination with the German Falcon 20 and the British Twin Otter aircraft. The aircraft flight paths covered large areas of Benin, Togo, Ghana and Côte d'Ivoire, focusing on emissions from large urban conurbations such as Abidjan, Accra and Lomé, as well as remote continental areas and the Gulf of Guinea. This paper focuses on aerosol particle measurements within the boundary layer (view of the complex mix of both biogenic and anthropogenic emissions, based on measurements from a compact time-of-flight aerosol mass spectrometer (C-ToF-AMS) and ancillary instrumentation. Background concentrations (i.e. outside urban plumes) observed from the ATR42 indicate a fairly polluted region during the time of the campaign, with average concentrations of carbon monoxide of 131 ppb, ozone of 32 ppb, and aerosol particle number concentration ( > 15 nm) of 735 cm-3 stp. Regarding submicron aerosol composition (considering non-refractory species and black carbon, BC), organic aerosol (OA) is the most abundant species contributing 53 %, followed by SO4 (27 %), NH4 (11 %), BC (6 %), NO3 (2 %) and minor contribution of Cl (< 0.5 %). Average background PM1 in the region was 5.9 µg m-3 stp. During measurements of urban pollution plumes, mainly focusing on the outflow of Abidjan, Accra and Lomé, pollutants are significantly enhanced (e.g. average concentration of CO of 176 ppb, and aerosol particle number concentration of 6500 cm-3 stp), as well as PM1 concentration (11.9 µg m-3 stp). Two classes of organic aerosols were

Preventive chemotherapy is the current strategy to control soil-transmitted helminth infections (caused by Ascaris lumbricoides, hookworm, and Trichuris trichiura). But, to improve efficacy and avoid emerging resistance, new drugs are warranted. Tribendimidine has shown good anthelmintic efficacy and is therefore a frontrunner for monotherapy and combination chemotherapy. We did a randomised, controlled, single-blinded, non-inferiority trial on Pemba Island, Tanzania, and in Côte d'Ivoire. We recruited adolescents aged 15-18 years from four primary schools on Pemba, and school attendees and non-schoolers from two districts in Côte d'Ivoire. Only hookworm-positive participants were randomly assigned (1:1:1:1) to single, oral doses of tribendimidine 400 mg plus placebo (tribendimidine monotherapy), tribendimidine 400 mg plus ivermectin 200 μg/kg, tribendimidine 400 mg plus oxantel pamoate 25 mg/kg, or albendazole 400 mg plus oxantel pamoate 25 mg/kg. Randomisation was done via a computer-generated list in block sizes of four or eight. Participants were asked to provide two stool samples on 2 consecutive days at baseline and again 14-21 days at follow-up. The primary outcome was the difference in egg-reduction rates (ERRs; ie, the geometric mean reduction) in hookworm egg counts between treatment groups, measured by the Kato-Katz technique. Differences in coadministrated treatment groups were assessed for non-inferiority with a margin of -3% to albendazole plus oxantel pamoate based on the available-case population, analysed by intention to treat. Safety was assessed 3 h and 24 h after treatment. This study is registered with ISRCTN (number 14373201). Between July 26, and Dec 23, 2016, we treated 636 hookworm-positive participants, and outcome data were available for 601 participants (151 assigned to tribendimidine monotherapy, 154 to tribendimidine plus ivermectin, 148 to tribendimidine plus oxantel pamoate, and 148 to albendazole plus oxantel pamoate

The vector control operations in the onchocerciasis control programme in West Africa

International Nuclear Information System (INIS)

Hougard, Jean-Marc

2000-01-01

Onchocerciasis is a dermal filariasis transmitted to man by a blood sucking blackfly belonging to the Simulium genus. The most serious manifestations of the disease are blindness and debilitating skin lesions. Africa is by far the most affected continent both in terms of distribution and severity of the clinical manifestations of the disease. That is the reason why an ambitious regional onchocerciasis control project, the Onchocerciasis Control Programme in West Africa (OCP), was launched in 1974 (Molyneux 1995). The objective is to eliminate onchocerciasis as a public health problem and as an obstacle to socio-economic development and to ensure that the countries are in a position to maintain these achievements. Seven countries were concerned at the beginning of the programme), delimiting the 'initial area' (Benin, Burkina Faso, Cote d'Ivoire, Ghana, Mali, Niger and Togo). In 1988, the OCP began operations in the 'western extension', an additional four countries in the West (Guinea, Guinea Bissau, Senegal and Sierra Leone) and extended operations into the 'southeastern extension' (south Benin, Ghana and Togo). The rationale for these extensions related to findings that the vectors were able to migrate and hence re-invade controlled areas over several hundred kilometres (Garms et al. 1979). Until 1989, in the absence of a non-toxic drug which could be used on a wide scale to kill the adult worm, the vector control strategy was the only method to interrupt the transmission of the blinding form of the parasite until the adult worm in the human body was eliminated (the maximum duration of the adult worm is estimated to be about fourteen years). In the late 1980s, ivermectin, a microfilaricide which is the only drug available to date, became an integral part of the OCP control strategy (Webbe 1992). In the extension areas, larviciding is still going on with satisfaction, combined with the distribution of ivermectin. In pursuing this combined therapeutic and vector

Factors Associated with Early Introduction of Formula and/or Solid, Semi-Solid or Soft Foods in Seven Francophone West African Countries

Full Text Available The aim of this study was to identify factors associated with early introduction of formula and/or solid, semi-solid or soft foods to infants aged three to five months in seven Francophone West African countries. The sources of data for the analyses were the most recent Demographic and Health Survey datasets of the seven countries, namely Benin (BDHS, 2012, Burkina Faso (BFDHS, 2010, Cote d’Ivoire (CIDHS, 2011–2012, Guinea (GDHS, 2012, Mali (MDHS, 2012–2013, Niger (NDHS, 2012 and Senegal (SDHS, 2010. The study used multiple logistic regression methods to analyse the factors associated with early introduction of complementary feeding using individual-, household- and community-level determinants. The sample was composed of 4158 infants aged between three and five months with: 671 from Benin, 811 from Burkina Faso, 362 from Cote d’Ivoire, 398 from Guinea, 519 from Mali, 767 from Niger and 630 from Senegal. Multiple analyses indicated that in three of the seven countries (Benin, Guinea and Senegal, infants who suffered illnesses, such as diarrhoea and acute respiratory infection, were significantly more likely to be introduced to formula and/or solid, semi-solid or soft foods between the age of three and five months. Other significant factors included infants who: were born in second to fourth position (Benin, whose mothers did not attend any antenatal clinics (Burkina Faso and Niger, were male (Cote d’Ivoire and Senegal, lived in an urban areas (Senegal, or were delivered by traditional birth attendants (Guinea, Niger and Senegal. Programmes to discourage early introduction of formula and/or solid, semi-solid or soft foods in these countries should target the most vulnerable segments of the population in order to improve exclusive breastfeeding practices and reduce infant mortality.

Male Circumcision and the Epidemic Emergence of HIV-2 in West Africa

Science.gov (United States)

Hewlett, Barry Stephen; Camacho, Ricardo Jorge

2016-01-01

Background Epidemic HIV-2 (groups A and B) emerged in humans circa 1930–40. Its closest ancestors are SIVsmm infecting sooty mangabeys from southwestern Côte d'Ivoire. The earliest large-scale serological surveys of HIV-2 in West Africa (1985–91) show a patchy spread. Côte d'Ivoire and Guinea-Bissau had the highest prevalence rates by then, and phylogeographical analysis suggests they were the earliest epicenters. Wars and parenteral transmission have been hypothesized to have promoted HIV-2 spread. Male circumcision (MC) is known to correlate negatively with HIV-1 prevalence in Africa, but studies examining this issue for HIV-2 are lacking. Methods We reviewed published HIV-2 serosurveys for 30 cities of all West African countries and obtained credible estimates of real prevalence through Bayesian estimation. We estimated past MC rates of 218 West African ethnic groups, based on ethnographic literature and fieldwork. We collected demographic tables specifying the ethnic partition in cities. Uncertainty was incorporated by defining plausible ranges of parameters (e.g. timing of introduction, proportion circumcised). We generated 1,000 sets of past MC rates per city using Latin Hypercube Sampling with different parameter combinations, and explored the correlation between HIV-2 prevalence and estimated MC rate (both logit-transformed) in the 1,000 replicates. Results and Conclusions Our survey reveals that, in the early 20th century, MC was far less common and geographically more variable than nowadays. HIV-2 prevalence in 1985–91 and MC rates in 1950 were negatively correlated (Spearman rho = -0.546, IQR: -0.553–-0.546, p≤0.0021). Guinea-Bissau and Côte d'Ivoire cities had markedly lower MC rates. In addition, MC was uncommon in rural southwestern Côte d'Ivoire in 1930.The differential HIV-2 spread in West Africa correlates with different historical MC rates. We suggest HIV-2 only formed early substantial foci in cities with substantial uncircumcised

Full Text Available OBJECTIVE: We assessed the 18-month effectiveness of short-course (sc antiretroviral peripartum regimens combined with alternatives to prolonged breastfeeding to prevent mother-to-child transmission (MTCT of HIV-1 in Abidjan, Côte d'Ivoire. METHODOLOGY: HIV-1 infected pregnant women received from >/=32-36 weeks of gestation scZidovudine (ZDV+/-Lamivudine (3TC+single-dose Nevirapine (sdNVP at delivery within the ANRS 1201/1202 DITRAME-Plus cohort (2001-2003. Neonates received a sdNVP+7-day ZDV prophylaxis. Two infant-feeding interventions were systematically offered free of charge: formula-feeding or exclusive shortened breastfeeding with early cessation from four months. The reference group was the ANRS 049a DITRAME cohort (1994-2000 exposed to scZDV from 36 weeks, then to prolonged breastfeeding. Pediatric HIV infection was defined by a positive plasma HIV-1 RNA at any age, or if aged >/=18 months, a positive HIV-1 serology. Turnbull estimates of cumulative transmission risks (CTR and effectiveness (HIV-free survival were compared by exposure group using a Cox model. FINDINGS: Among 926 live-born children enrolled, 107 (11.6% were HIV-infected at 18 months. CTRs were 22.3% (95% confidence interval[CI]:16-30% in the 238 ZDV long-term breastfed reference group, 15.9% (CI:10-27% in the 169 ZDV+sdNVP shortened breastfed group; 9.4% (CI:6-14% in the 195 ZDV+sdNVP formula-fed group; 6.8% (CI:4-11% in the 198 ZDV+3TC+sdNVP shortened breastfed group, and 5.6% (CI:2-10% in the 126 ZDV+3TC+sdNVP formula-fed group. Each combination had a significantly higher effectiveness than the ZDV long-term breastfed group except for ZDV+sdNVP shortened breastfed children, ranging from 51% (CI:20-70% for ZDV+sdNVP formula fed children to 63% (CI:40-80% for ZDV+3TC+NVPsd shortened breastfed children, after adjustment for maternal eligibility for antiretroviral therapy (ART, home delivery and low birth-weight.

Gender-based violence against women, including intimate partner violence (IPV), is a pervasive health and human rights concern. However, relatively little intervention research has been conducted on how to reduce IPV in settings impacted by conflict. The current study reports on the evaluation of the incremental impact of adding "gender dialogue groups" to an economic empowerment group savings program on levels of IPV. This study took place in north and northwestern rural Côte d'Ivoire. Between 2010 and 2012, we conducted a two-armed, non-blinded randomized-controlled trial (RCT) comparing group savings only (control) to "gender dialogue groups" added to group savings (treatment). The gender dialogue group consisted of eight sessions that targeted women and their male partner. Eligible Ivorian women (18+ years, no prior experience with group savings) were invited to participate. 934 out of 981 (95.2%) partnered women completed baseline and endline data collection. The primary trial outcome measure was an overall measure of past-year physical and/or sexual IPV. Past year physical IPV, sexual IPV, and economic abuse were also separately assessed, as were attitudes towards justification of wife beating and a woman's ability to refuse sex with her husband. Intent to treat analyses revealed that compared to groups savings alone, the addition of gender dialogue groups resulted in a slightly lower odds of reporting past year physical and/or sexual IPV (OR: 0.92; 95% CI: 0.58, 1.47; not statistically significant). Reductions in reporting of physical IPV and sexual IPV were also observed (not statistically significant). Women in the treatment group were significantly less likely to report economic abuse than control group counterparts (OR = 0.39; 95% CI: 0.25, 0.60, p < .0001). Acceptance of wife beating was significantly reduced among the treatment group (β = -0.97; 95% CI: -1.67, -0.28, p = 0.006), while attitudes towards refusal of sex did not significantly change Per

Preventive chemotherapy with donated anthelminthic drugs is the cornerstone for the control of helminthiases. However, reinfection can occur rapidly in the absence of clean water and sanitation coupled with unhygienic behaviour. The purpose of this study was to assess the effect of an integrated package of interventions, consisting of preventive chemotherapy, community-led total sanitation (CLTS) and health education, on the prevalence of helminth and intestinal protozoa infections and on participants' knowledge, attitude, practice and beliefs (KAPB) towards these diseases including water, sanitation and hygiene (WASH). A cross-sectional survey was carried out in nine communities of south-central Côte d'Ivoire to assess people's infection with helminths and intestinal protozoa and KAPB. Subsequently, interventions were targeted to five communities, while the remaining communities served as control. The intervention encouraged latrine construction and an evaluation was done 6-7 months later to determine open defecation status of the respective communities. Anthelminthic treatment was provided to all community members. A follow-up cross-sectional survey was conducted approximately one year later, using the same procedures. Overall, 810 people had complete baseline and follow-up data and were given anthelminthic treatment. The baseline prevalence of hookworm, Schistosoma haematobium, Trichuris trichiura, Schistosoma mansoni and Ascaris lumbricoides was 31.1%, 7.0%, 2.0%, 1.0% and 0.3%, respectively. Four of the five intervention communities were classified open-defecation free. For hookworm infection, we observed higher negative changes in terms of proportion of decrease (-0.10; 95% confidence interval (CI): - 0.16, -0.04) and higher egg reduction rate (64.9 vs 15.2%) when comparing intervention with control communities. For intestinal protozoa, prevalence reduction was higher in intervention compared to control communities (8.2 vs 2.6%) and WASH indicators and

Over the past 30 years, Zaire and Sudan ebolaviruses have been responsible for large hemorrhagic fever (HF) outbreaks with case fatalities ranging from 53% to 90%, while a third species, Côte d'Ivoire ebolavirus, caused a single non-fatal HF case. In November 2007, HF cases were reported in Bundibugyo District, Western Uganda. Laboratory investigation of the initial 29 suspect-case blood specimens by classic methods (antigen capture, IgM and IgG ELISA) and a recently developed random-primed pyrosequencing approach quickly identified this to be an Ebola HF outbreak associated with a newly discovered ebolavirus species (Bundibugyo ebolavirus) distantly related to the Côte d'Ivoire ebolavirus found in western Africa. Due to the sequence divergence of this new virus relative to all previously recognized ebolaviruses, these findings have important implications for design of future diagnostic assays to monitor Ebola HF disease in humans and animals, and ongoing efforts to develop effective antivirals and vaccines.

Bacillus spores are encased in a multilayer, proteinaceous self-assembled coat structure that assists in protecting the bacterial genome from stresses and consists of at least 70 proteins. The elucidation of Bacillus spore coat assembly, architecture, and function is critical to determining mechanisms of spore pathogenesis, environmental resistance, immune response, and physicochemical properties. Recently, genetic, biochemical and microscopy methods have provided new insight into spore coat architecture, assembly, structure and function. However, detailed spore coat architecture and assembly, comprehensive understanding of the proteomic composition of coat layers, and specific roles of coat proteins in coat assembly and their precise localization within the coat remain in question. In this study, atomic force microscopy was used to probe the coat structure of Bacillus subtilis wild type and cotA, cotB, safA, cotH, cotO, cotE, gerE, and cotE gerE spores. This approach provided high-resolution visualization of the various spore coat structures, new insight into the function of specific coat proteins, and enabled the development of a detailed model of spore coat architecture. This model is consistent with a recently reported four-layer coat assembly and further adds several coat layers not reported previously. The coat is organized starting from the outside into an outermost amorphous (crust) layer, a rodlet layer, a honeycomb layer, a fibrous layer, a layer of "nanodot" particles, a multilayer assembly, and finally the undercoat/basement layer. We propose that the assembly of the previously unreported fibrous layer, which we link to the darkly stained outer coat seen by electron microscopy, and the nanodot layer are cotH- and cotE- dependent and cotE-specific respectively. We further propose that the inner coat multilayer structure is crystalline with its apparent two-dimensional (2D) nuclei being the first example of a non-mineral 2D nucleation crystallization

Full Text Available As part of the Dynamics-Aerosol-Chemistry-Cloud Interactions in West Africa (DACCIWA project, an airborne campaign was designed to measure a large range of atmospheric constituents, focusing on the effect of anthropogenic emissions on regional climate. The presented study details results of the French ATR42 research aircraft, which aimed to characterize gas-phase, aerosol and cloud properties in the region during the field campaign carried out in June/July 2016 in combination with the German Falcon 20 and the British Twin Otter aircraft. The aircraft flight paths covered large areas of Benin, Togo, Ghana and Côte d'Ivoire, focusing on emissions from large urban conurbations such as Abidjan, Accra and Lomé, as well as remote continental areas and the Gulf of Guinea. This paper focuses on aerosol particle measurements within the boundary layer (<  2000 m, in particular their sources and chemical composition in view of the complex mix of both biogenic and anthropogenic emissions, based on measurements from a compact time-of-flight aerosol mass spectrometer (C-ToF-AMS and ancillary instrumentation. Background concentrations (i.e. outside urban plumes observed from the ATR42 indicate a fairly polluted region during the time of the campaign, with average concentrations of carbon monoxide of 131 ppb, ozone of 32 ppb, and aerosol particle number concentration ( >  15 nm of 735 cm−3 stp. Regarding submicron aerosol composition (considering non-refractory species and black carbon, BC, organic aerosol (OA is the most abundant species contributing 53 %, followed by SO4 (27 %, NH4 (11 %, BC (6 %, NO3 (2 % and minor contribution of Cl (<  0.5 %. Average background PM1 in the region was 5.9 µg m−3 stp. During measurements of urban pollution plumes, mainly focusing on the outflow of Abidjan, Accra and Lomé, pollutants are significantly enhanced (e.g. average concentration of CO of 176 ppb, and aerosol
