    SIDA Dans La Cite (AIDS in the City) is a popular weekly soap opera first broadcast in Cote d'Ivoire in 1991 with 11 15-minute episodes. The series is part of a campaign by Population Services International (PSI) to raise awareness about AIDS among Ivorian youth. Actors worked for a nominal fee, editing studios were provided at substantial discounts, and filming equipment was borrowed for next to nothing. Production director realized how important the soap opera had become after the fourth episode. A study of 700 households in Abidjan found that of the 75% who had access to a television, two-thirds had seen at least one episode. Cote d'Ivoire may be one of the most religiously conservative countries in Africa. 10% of the adult population, however, is infected with HIV. All sectors of society therefore understand the need to openly understand and discuss sexual issues in the context of such high HIV prevalence. Studies indicate that virtually everyone in Cote d'Ivoire has heard of AIDS and knows that it is a sexually transmitted disease, but persuading people to change their behavior is difficult. PSI sells approximately 750,000 of its subsidized Prudence condoms. Prudence has the same brand recognition in the country as Nescafe and Toyota. A recent survey of sexually active teens found that 30% of girls and 45% of boys used condoms. A weekly radio show is broadcast live from one of the poorest ghettos of Abidjan. Guests include popular singers, comedians, and television personalities. The actors are often from SIDA Dans La Cite.

    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 C\\^{o}te 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 d...

    Full Text Available Men and women's perceptions of intimate partner violence (IPV within crisis-affected populations are not well understood. This mixed-methods study examined the frequency of IPV against women in urban Cote d'Ivoire, and qualitatively explored how men and women perceive the impact of various forms of IPV on health, everyday activities, and feelings of shame.A survey was administered to Ivorian women (N = 80 to measure the frequency of IPV, and ten focus group discussions were conducted with women (n = 46 and men (n = 45 to explore perceptions of different forms of IPV, including its impacts on disruptions to health, everyday activities, and experiences of shame.Half of all surveyed women (53.6% reported past year exposure to physical, sexual, or emotional IPV. Of the multiple types of violence, emotional IPV was most common (46.4%, followed by sexual IPV (21.7% and physical IPV (17.4%. Focus group participants identified additional forms of violence including economic IPV and community discrimination. Lack of financial resources and unemployment were common problems among crisis-affected women and were described as an underlying source of IPV. Both women and men reported that shame and stigma play a large role in how women experience the repercussions of IPV, regardless of the form of violence, with public episodes of IPV almost always seen as more detrimental than private episodes of IPV.These results underscore the need for increased social support mechanisms for women to reduce the shame, stigma, and isolation associated with their experiences. The creation of safe and supportive spaces for women to talk about and challenge social norms may be an important first step in reducing community shaming and the secrecy that often surrounds IPV. Safe spaces along with broader societal outreach, including challenging men's social positions and creating opportunities for increasing economic resources can, in turn potentially decrease the frequency of IPV

    In this paper, we theorize about the impacts of human resource management ( HRM ) practices on enterprises' performance in Abidjan (Cote d'Ivoire). Specifically, we emphasize the correlation between HRM practices and the perceived enterprise performance. A factor analysis of different HRM practices was utilized. The exploratory factor analysis on the HRM practices for managerial employees revealed three HRM dimensions: employee development, feedback systems, and pay/ organization. A separate factor analysis for HRM practices for non-managerial employees led to the same conclusions. These three factors resemble those obtained in previous empirical study and discussed in the theoretical HRM literature. Therefore, the relationship among these three HRM dimensions and their relationship with enterprise performance was examined in the present study to facilitate comparison between managerial and non-managerial employees in the Ivorian context.

  8. Artisanal Fishery And Sustainable Management Of Stock Of Blue Marlins Makaira Nigricans In Marine Waters Of Cote dIvoire.

    Full Text Available This study focuses on the small-scale artisanal fishery that captures blue marlins Makaira nigricans in Cote dIvoire. The sizes weights and quantities landed of this species were approached according to the marine seasons and fishing areas. These fishermen mostly Ghanaians use canoes 12 to 17 m as craft and drifting gillnets 4800 to 5400 m to catch fish. The choice of fishing area depends on the direction of the current. When the current flows westward fishing takes place in the east and vice versa. These choices have the advantage that at the return the driving force is developed in the direction of the current. In either case the net is arranged perpendicularly to the direction of the current to act as a filtering barrier. In the absence of marine current the net is arranged perpendicularly to the north-south axis. The Man-Whitney test applied to maturity states following seasons and fishing areas showed a significant difference P 0.05. Sector A2 offshore waters in front of Abidjan Grand Bassam and Jacqueville would be conducive to the capture of mature individuals during warm seas. On the other hand during upwelling fishing should be favorable to sector B offshore waters in front of Grand-Lahou and Fresco where adult marlins are accessible. Capturing M. nigricans on the continental shelf should be discouraged as recruits abound in this area to feed and shelter from large offshore predators.

    In temperate regions, influenza epidemics occur in the winter and correlate with certain climatological parameters. In African tropical regions, the effects of climatological parameters on influenza epidemics are not well defined. This study aims to identify and model the effects of climatological parameters on seasonal influenza activity in Abidjan, Cote d'Ivoire. We studied the effects of weekly rainfall, humidity, and temperature on laboratory-confirmed influenza cases in Abidjan from 2007 to 2010. We used the Box-Jenkins method with the autoregressive integrated moving average (ARIMA) process to create models using data from 2007-2010 and to assess the predictive value of best model on data from 2011 to 2012. The weekly number of influenza cases showed significant cross-correlation with certain prior weeks for both rainfall, and relative humidity. The best fitting multivariate model (ARIMAX (2,0,0) _RF) included the number of influenza cases during 1-week and 2-weeks prior, and the rainfall during the current week and 5-weeks prior. The performance of this model showed an increase of >3 % for Akaike Information Criterion (AIC) and 2.5 % for Bayesian Information Criterion (BIC) compared to the reference univariate ARIMA (2,0,0). The prediction of the weekly number of influenza cases during 2011-2012 with the best fitting multivariate model (ARIMAX (2,0,0) _RF), showed that the observed values were within the 95 % confidence interval of the predicted values during 97 of 104 weeks. Including rainfall increases the performances of fitted and predicted models. The timing of influenza in Abidjan can be partially explained by rainfall influence, in a setting with little change in temperature throughout the year. These findings can help clinicians to anticipate influenza cases during the rainy season by implementing preventive measures.

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

    Directory of Open Access Journals (Sweden)

    Paul Capewell

    Full Text Available BACKGROUND: 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. METHODOLOGY/PRINCIPAL FINDINGS: 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. CONCLUSIONS/SIGNIFICANCE: 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.

    The effects of HIV/AIDS have been far-reaching in Africa. Beyond adverse health outcomes and the tremendous toll on life, AIDS has serious economic impacts on households, increasing livelihood insecurity while simultaneously depleting socio-economic resources. Although microfinance is believed to have the potential to mitigate the economic impacts of HIV by helping affected households and communities better prepare for and cope with HIV-related economic shocks, little empirical research exists on this subject. This qualitative study examines the socio-economic impacts of economic strengthening activities on people living with HIV (PLHIV) in the era of increased access to anti-retroviral therapy to determine if savings-led, community-managed microfinance is a justified activity for HIV programmes. Findings from a village savings and loan programme, implemented by CARE International in Cote d'Ivoire, revealed that when appropriate medical treatment is available PLHIV are capable of participating in and benefit from microfinance activities, which increased HIV-positive clients' access to money and economic self-sufficiency. By bringing individuals with similar experiences together, savings and loan groups also acted as self-support groups providing psychosocial support while reducing stigmatisation and increasing members' sense of dignity and self-worth.

    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.

    Alphonsine A Koffi

    Full Text Available Insecticide resistance constitutes a major threat that may undermine current gain in malaria control in most endemic countries. National Malaria Control Programmes (NMCPs need as much information as possible on the resistance status of malaria vectors and underlying mechanisms in order to implement the most relevant and efficient control strategy. Bioassays, biochemical and molecular analysis were performed on An. gambiae collected in six sentinel sites in Côte d'Ivoire. The sites were selected on the basis of their bioclimatic status and agricultural practices. An. gambiae populations across sites showed high levels of resistance to organochloride, pyrethroid and carbamate insecticides. The kdr and ace-1(R mutations were detected in almost all sentinel sites with mosquitoes on the coastal and cotton growing areas mostly affected by these mutations. At almost all sites, the levels of detoxifying enzymes (mixed-function oxidases (MFOs, non-specific esterases (NSE and glutathione-S-transferases (GSTs in An. gambiae populations were significantly higher than the levels found in the susceptible strain Kisumu. Pre-exposure of mosquitoes to PBO, an inhibitor of MFOs and NSEs, significantly increased mortality rates to pyrethroids and carbamates in mosquitoes but resistance in most cases was not fully synergised by PBO, inferring a residual role of additional mechanisms, including kdr and ace-1 site insensitivity. The large distribution of resistance in Côte d'Ivoire raises an important question of whether to continue to deploy pyrethroid-based long-lasting insecticidal nets (LLINs and insecticide residual spraying (IRS towards which resistance continues to rise with no guarantee that the level of resistance would not compromise their efficacy. Innovative strategies that combine insecticide and synergists in LLINs or spatially LLIN and an effective non-pyrethroid insecticide for IRS could be in the short term the best practice for the NMCP to manage

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

    Kévin Jean

    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.

    Timothée Ouassa

    Full Text Available BACKGROUND: Genotyping methods are useful tools to provide information on tuberculosis epidemic. They can allow a better response from health authorities and the implementation of measures for tuberculosis control. This study aimed to identify the main lineages and clades of Mycobacterium tuberculosis complex strains circulating in Côte d'Ivoire. METHODS/MAIN FINDINGS: Strains isolated from sputum samples of patients ongoing retreatment from all the country were characterized by spoligotyping and by MIRU-VNTR. Profiles obtained by spoligotyping were first compared to the SITVIT/SpolDB4 database for family assignment. Of 194 strains analysed, 146 (75.3% belonged to the T lineage. The most predominant spoligotype was the shared international type 53 with 135 strains (69.6%. In contrast with neighbouring countries, LAM (11 strains, 5.7% and H (9 strains 4.6% lineages were slightly represented. Only 3 Beijing strains (1.5% and 4 strains of Mycobacterium africanum (2% were found. Analysis of the results obtained with MIRU-VNTR revealed also a high level of clustering. CONCLUSION/SIGNIFICANCE: The population of Mycobacterium tuberculosis complex strains among retreatment cases in Côte d'Ivoire exhibits a low diversity, allowing to assume recent transmission and locally based infection.

  18. Dual Simian Foamy Virus/Human Immunodeficiency Virus Type 1 Infections in Persons from Cote d'Ivoire.

    Directory of Open Access Journals (Sweden)

    William M Switzer

    Full Text Available Zoonotic transmission of simian retroviruses in West-Central Africa occurring in primate hunters has resulted in pandemic spread of human immunodeficiency viruses (HIVs and human T-lymphotropic viruses (HTLVs. While simian foamy virus (SFV and simian T- lymphotropic virus (STLV-like infection were reported in healthy persons exposed to nonhuman primates (NHPs in West-Central Africa, less is known about the distribution of these viruses in Western Africa and in hospitalized populations. We serologically screened for SFV and STLV infection using 1,529 specimens collected between 1985 and 1997 from Côte d'Ivoire patients with high HIV prevalence. PCR amplification and analysis of SFV, STLV, and HIV/SIV sequences from PBMCs was used to investigate possible simian origin of infection. We confirmed SFV antibodies in three persons (0.2%, two of whom were HIV-1-infected. SFV polymerase (pol and LTR sequences were detected in PBMC DNA available for one HIV-infected person. Phylogenetic comparisons with new SFV sequences from African guenons showed infection likely originated from a Chlorocebus sabaeus monkey endemic to Côte d'Ivoire. 4.6% of persons were HTLV seropositive and PCR testing of PBMCs from 15 HTLV seroreactive persons identified nine with HTLV-1 and one with HTLV-2 LTR sequences. Phylogenetic analysis showed that two persons had STLV-1-like infections, seven were HTLV-1, and one was an HTLV-2 infection. 310/858 (53%, 8/858 (0.93%, and 18/858 (2.1% were HIV-1, HIV-2, and HIV-positive but undifferentiated by serology, respectively. No SIV sequences were found in persons with HIV-2 antibodies (n = 1 or with undifferentiated HIV results (n = 7. We document SFV, STLV-1-like, and dual SFV/HIV infection in Côte d'Ivoire expanding the geographic range for zoonotic simian retrovirus transmission to West Africa. These findings highlight the need to define the public health consequences of these infections. Studying dual HIV-1/SFV infections in

    We present the microbiological and molecular characterization of bacteria isolated from four chimpanzees and one gorilla thought to have died of an anthrax-like disease in Côte d'Ivoire and Cameroon. These isolates differed significantly from classic Bacillus anthracis by the following criteria: motility, resistance to the gamma phage, and, for isolates from Cameroon, resistance to penicillin G. A capsule was expressed not only after induction by CO(2) and bicarbonate but also under normal growth conditions. Subcultivation resulted in beta-hemolytic activity and gamma phage susceptibility in some subclones, suggesting differences in gene regulation compared to classic B. anthracis. The isolates from Côte d'Ivoire and Cameroon showed slight differences in their biochemical characteristics and MICs of different antibiotics but were identical in all molecular features and sequences analyzed. PCR and Southern blot analyses confirmed the presence of both the toxin and the capsule plasmid, with sizes corresponding to the B. anthracis virulence plasmids pXO1 and pXO2. Protective antigen was expressed and secreted into the culture supernatant. The isolates possessed variants of the Ba813 marker and the SG-749 fragment differing from that of classic B. anthracis strains. Multilocus sequence typing revealed a close relationship of our atypical isolates with both classic B. anthracis strains and two uncommonly virulent Bacillus cereus and Bacillus thuringiensis isolates. We propose that the newly discovered atypical B. anthracis strains share a common ancestor with classic B. anthracis or that they emerged recently by transfer of the B. anthracis plasmids to a strain of the B. cereus group.

    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.

  1. Effects of hygiene and defecation behavior on helminths and intestinal protozoa infections in Taabo, Cote d'Ivoire.

    Thomas Schmidlin

    Full Text Available BACKGROUND: 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. METHODOLOGY: 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. PRINCIPAL FINDINGS: 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. CONCLUSIONS/SIGNIFICANCE: We found that inadequate sanitation and hygiene behavior are associated with soil-transmitted helminths and intestinal protozoa infections in the Taabo

    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

    Full Text Available To determine HIV prevalence and associated risk factors among men who have sex with men (MSM in Abidjan, Côte d'Ivoire. We conducted a cross-sectional RDS survey of MSM in Abidjan from October 2011 to February 2012. Eligibility criteria included age ≥ 18 years and having had oral or anal sex with another man in the last 12 months. Weighted data analysis was conducted with RDSAT and SAS. We enrolled 603 participants, of whom 601 (99.7% completed the questionnaire and 581 (96.7% consented to HIV testing. HIV population prevalence was estimated as 18.0% (95% CI: 13.0-23.1; 86.4% (95% CI: 75.1-94.9 of HIV-positive MSM were unaware of their serostatus. In multivariable analysis, adjusting for age, education, and income, HIV infection was associated with unprotected sex at last sex with a woman, more than two male anal sex partners in last 12 months, inconsistent condom use during anal sex with a man, self-perceived risk of HIV, history of forced sex, history of physical abuse due to MSM status, and not receiving last HIV test result prior to study. HIV prevalence among MSM in Abidjan is more than four times as high as that of general population men. MSM engage in high-risk sexual behavior and most HIV-positive MSM are unaware of their serostatus. Greater access to HIV prevention, care, and treatment services targeted to MSM is necessary.

    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.

    Full Text Available BACKGROUND: Objectives were to assess associations between intimate partner violence (IPV, violence during armed conflict (i.e. crisis violence, and probable post-traumatic stress disorder (PTSD. METHODS: Using a sample of 950 women in rural Côte d'Ivoire, logistic generalized estimating equations assessed associations between IPV and crisis violence exposures with past-week probable PTSD. RESULTS: Over one in 5 (23.4% women reported past-year IPV, and over one in 4 women (26.5% reported experiencing IPV prior to the past year (i.e. remote IPV. Crisis violence was experienced by 72.6% of women. In adjusted models including demographics, crisis violence (overall and specific forms, and IPV (remote and past-year, women who reported past-year IPV had 3.1 times the odds of reporting probable past-week PTSD (95%CI: 1.8-5.3 and those who reported remote IPV had 1.6 times the odds (95%CI: 0.9-2.7. Violent exposures during the crisis were not significantly associated with probable PTSD (any crisis violence: aOR: 1.04 (0.7-1.5; displacement: aOR: 0.9 (95%CI: 0.5-1.7; family victimization during crisis: aOR: 1.1 (95%CI: 0.8-1.7; personal victimization during crisis: aOR: 1.7 (95%CI: 0.7-3.7. CONCLUSION: Past-year IPV was more strongly associated with past-week probable PTSD than remote IPV and violence directly related to the crisis. IPV must be considered within humanitarian mental health and psychosocial programming.

  6. Wide Variations in Compliance with Tuberculosis Screening Guidelines and Tuberculosis Incidence between Antiretroviral Therapy Facilities - Cote d'Ivoire.

    Andrew F Auld

    Full Text Available In Côte d'Ivoire, tuberculosis (TB is a common cause of death among HIV-infected antiretroviral therapy (ART enrollees. Ivorian guidelines recommend screening for TB and initiation of TB treatment before ART initiation. Compliance with these guidelines can help reduce TB-related mortality during ART and possibly nosocomial TB transmission.In a retrospective cohort study among 3,682 randomly selected adults (≥15 years old starting ART during 2004-2007 at 34 randomly selected facilities, documentation of TB screening completion, prevalence of active TB at ART initiation, and incidence of TB during ART were evaluated. At ART initiation, median age was 36 years, 67% were female, and median CD4 count was 135 cells/μL. Among all 3,682 enrollees, 73 (2% were on TB treatment at the time of referral to the ART facility. Among the 3,609 not on TB treatment, 1,263 (36% were documented to receive some TB screening before ART initiation; 21% were screened for cough, 21% for weight loss, 18% for fever, 18% for TB contacts, and 12% for night sweats. Among the 1,263 screened, 111 (11% were diagnosed with TB and started TB treatment before ART. No associations between patient characteristics and probability of being screened were noted. However, documentation of TB screening completion before ART varied widely by ART facility from 0-100%. TB incidence during ART was 3.0 per 100 person-years but varied widely by ART facility from 0/100 person-year to 13.1/100 person-years.Screening for TB before ART initiation was poorly documented. Facility-level variations in TB screening documentation suggest facility-level factors, such as investment in training programs, might determine documentation practices. Targeting under-performing ART facilities with improvement activities is needed. Variations among facilities in TB incidence warrant further research. These incidence variations could reflect differences between facilities in TB screening, diagnostic tests

    Jean Anderson

    Full Text Available HIV infection increases a woman's risk for cervical cancer, and cervical cancer incidence and mortality rates are higher in countries with high HIV prevalence and limited resources for screening. Visual inspection with acetic acid (VIA allows screening and treatment of cervical lesions in a single-visit approach (SVA, but data on its performance in HIV-infected women are limited. This study's objective was to examine cervical cancer screening using VIA/SVA in programs serving HIV-infected women.A VIA/SVA program with cryotherapy for VIA-positive lesions was implemented in Côte d'Ivoire, Guyana, and Tanzania from 2009 to 2012. The effect of HIV status on VIA positivity and on presence of cryotherapy-eligible lesions was examined using a cross-sectional study design, with Chi-square tests for comparisons and constructed multivariate logistic regression models. A P-value of < 0.05 was significant.VIA was performed on 34,921 women, 10% (3,580 were VIA positive; 2,508 (85% eligible women received cryotherapy during the same visit; only 234 (52% of those who postponed returned for treatment; 622 (17% VIA-positive women had lesions too large to be treated with cryotherapy and were referred for excisional treatment. In multivariate analysis-controlling for HIV status, location of the screening clinic, facility location, facility type, and country-compared to HIV-uninfected/unknown women, HIV-infected women had higher odds of being VIA positive (OR 1.95, 95% CI 1.76, 2.16, P<0.0001 and of having large lesions requiring referral (OR 1.93, 95% CI 1.49, 2.51, P< 0.0001. Minor treatment complications occurred in 19 of 3,032 (0.63% women; none required further intervention.This study found that compared to HIV-uninfected/unknown women, HIV-infected women had nearly twice the odds of being VIA-positive and to require referral for large lesions. SVA was safe and resulted in significant reductions in loss to follow-up. There is increased need for excisional

    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

    Roche, Helene; Tidou, Abiba; Persic, Ana

    The concentrations of organochlorine pesticides (OCPs) were determined in muscle samples of two species of fish, tilapia (Oreochromis niloticus) and the catfish (Chrysichthys nigrodigitatus) and the prawn (Macrobrachium vollenhovenii) found in Lake Taabo (Cote d`Ivoire). Simultaneous measurements of enzymatic biomarkers were made to evaluate the ecotoxicological risk in this hydroelectric reservoir. Lindane and endosulfan were the dominant contaminants, suggesting their current use in neighboring agricultural areas. Other organochlorine (OC) compounds were detected, including some currently banned substances. Ranked in an order of descending concentrations, we found: DDT and its metabolites (17.8-57.2 ng g-1 dry weight), endrin (7.17-25.0 ng g-1 dry weight) and heptachlor (7.36-23.6 ng g-1 dry weight), as well as traces of isomers of chlordane, aldrin and fipronil. The hepatic Glutathione S-Transferase (GST) activity measured in fishes was not correlated with pesticide contamination; whereas the antioxidant biomarkers demonstrated some significant associations, especially hepatic catalase with lindane (R = 0.83) and Glutathione Peroxidase (GPx) with heptachlor epoxide (R = 0.84) and with pp`DDT (R = 0.81). In the prawns, acetylcholinesterase (AChE) activity showed significant negative correlations with DDT and its metabolites (R = -0.91). The results of this study emphasize the urgent need for overall environmental risk assessment studies in the region of Taabo and other developing areas.

    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.

    Bea Vuylsteke

    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.

    This study is a contribution to the WP2-DACCIWA program with the aim to characterize particulate pollution on domestic fire site, traffic sites and waste burning site of two West-African capitals (Abidjan, Cote d'Ivoire and Cotonou, Benin) and to study aerosol biological impacts on lung inflammation. Such an impact is still largely unknown, especially for the particles emitted by intense African traffic sources and domestic fires. In this context, fundamental research of this study is centered on the following key scientific question: what is the link between aerosol size differentiated composition and inflammation markers for the main combustion sources prevailing in South West Africa during dry and wet seasons? To tackle this question, intensive campaigns in Abidjan and Cotonou have been conducted in July 2015, January and July 2016, and January 2017. In this paper, we will present our first results for the campaign of January 2016. In terms of aerosol size differentiated composition, main aerosol components (mass, black carbon, organic carbon, water soluble particles ...) were measured. We may notice that PM measured for all the sites is generally higher than WHO norms. Organic carbon and dust particles are the two more important contributors for the ultra-fine and fine particle sizes with more organic carbon in Abidjan and dust particles in Cotonou respectively. In terms of in vitro biological studies on sampled aerosols on these sites, size-fractionated PM from the different sampling sites were compared for their ability to induce a proinflammatory response characterized by the release of the cytokine IL-6 by human bronchial epithelial cells. PM from waste burning site did not induce significant IL-6 release whatever the size fraction whereas PM from domestic fire were the most reactive especially the ultra-fine fraction. Ultra-fine particles from traffic (Abidjan and Cotonou) always induced a dose-dependent IL-6 release. A tentative cross-analysis between

    Thomas Fürst

    Full Text Available BACKGROUND: 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. METHODOLOGY: 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. PRINCIPAL FINDINGS: 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. CONCLUSIONS

    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. CONCLUSIONS/SIGNIFICANCE: More

    Directory of Open Access Journals (Sweden)

    Christiane Essoh

    Full Text Available Twenty two distinct bacteriophages were isolated from sewage water from five locations in the city of Abidjan, Côte d'Ivoire over a two-year period, using a collection of Pseudomonas aeruginosa strains with diverse genotypes. The phages were characterized by their virulence spectrum on a panel of selected P. aeruginosa strains from cystic fibrosis patients and by whole genome sequencing. Twelve virions representing the observed diversity were visualised by electron microscopy. The combined observations showed that 17 phages, distributed into seven genera, were virulent, and that five phages were related to temperate phages belonging to three genera. Some showed similarity with known phages only at the protein level. The vast majority of the genetic variations among virulent phages from the same genus resulted from seemingly non-random horizontal transfer events, inside a population of P. aeruginosa phages with limited diversity. This suggests the existence of a single environmental reservoir or ecotype in which continuous selection is taking place. In contrast, mostly point mutations were observed among phages potentially capable of lysogenisation. This is the first study of P. aeruginosa phage diversity in an African city and it shows that a large variety of phage species can be recovered in a limited geographical site at least when different bacterial strains are used. The relative temporal and spatial stability of the Abidjan phage population might reflect equilibrium in the microbial community from which they are released.

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

    Directory of Open Access Journals (Sweden)

    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.

  1. Interactions and potential implications of Plasmodium falciparum-hookworm coinfection in different age groups in south-central Cote d'Ivoire.

    Directory of Open Access Journals (Sweden)

    Aurélie A Righetti

    Full Text Available BACKGROUND: Given the widespread distribution of Plasmodium and helminth infections, and similarities of ecological requirements for disease transmission, coinfection is a common phenomenon in sub-Saharan Africa and elsewhere in the tropics. Interactions of Plasmodium falciparum and soil-transmitted helminths, including immunological responses and clinical outcomes of the host, need further scientific inquiry. Understanding the complex interactions between these parasitic infections is of public health relevance considering that control measures targeting malaria and helminthiases are going to scale. METHODOLOGY: A cross-sectional survey was carried out in April 2010 in infants, young school-aged children, and young non-pregnant women in south-central Côte d'Ivoire. Stool, urine, and blood samples were collected and subjected to standardized, quality-controlled methods. Soil-transmitted helminth infections were identified and quantified in stool. Finger-prick blood samples were used to determine Plasmodium spp. infection, parasitemia, and hemoglobin concentrations. Iron, vitamin A, riboflavin, and inflammation status were measured in venous blood samples. PRINCIPAL FINDINGS: Multivariate regression analysis revealed specific association between infection and demographic, socioeconomic, host inflammatory and nutritional factors. Non-pregnant women infected with P. falciparum had significantly lower odds of hookworm infection, whilst a significant positive association was found between both parasitic infections in 6- to 8-year-old children. Coinfected children had lower odds of anemia and iron deficiency than their counterparts infected with P. falciparum alone. CONCLUSIONS/SIGNIFICANCE: Our findings suggest that interaction between P. falciparum and light-intensity hookworm infections vary with age and, in school-aged children, may benefit the host through preventing iron deficiency anemia. This observation warrants additional investigation to

    Full Text Available BACKGROUND: Facing the dual burden of invasive cervical cancer and HIV in sub-Saharan Africa, the identification of preventable determinants of Cervical Intraepithelial Neoplasia (CIN in HIV-infected women is of paramount importance. METHODS: A cervical cancer screening based on visual inspection methods was proposed to HIV-infected women in care in Abidjan, Côte d'Ivoire. Positively screened women were referred for a colposcopy to a gynaecologist who performed directed biopsies. RESULTS: Of the 2,998 HIV-infected women enrolled, 132 (4.4% CIN of any grade (CIN+ were identified. Women had been followed-up for a median duration of three years [IQR: 1-5] and 76% were on antiretroviral treatment (ART. Their median most recent CD4 count was 452 [IQR: 301-621] cells/mm3. In multivariate analysis, CIN+ was associated with a most recent CD4 count >350 cells/mm3 (OR: 0.3; 95% CI: 0.2-0.6 or ≥200-350 cells/mm3 (OR 0.6; 95% CI 0.4-1.0 (Ref: <200 cells/mm3 CD4 (p<10-4. CONCLUSIONS: The presence of CIN+ is less common among HIV-infected women with limited or no immune deficiency. Despite the potential impact of immunological recovery on the reduction of premalignant cervical lesions through the use of ART, cervical cancer prevention, including screening and vaccination remains a priority in West Africa while ART is rolled-out.

    Full Text Available BACKGROUND: Universal HIV pediatric screening offered at postnatal points of care (PPOC is an entry point for early infant diagnosis (EID. We assessed the parents' acceptability of this approach in Abidjan, Côte d'Ivoire. METHODS: In this cross-sectional study, trained counselors offered systematic HIV screening to all children aged 6-26 weeks attending PPOC in three community health centers with existing access to HAART during 2008, as well as their parents/caregivers. HIV-testing acceptability was measured for parents and children; rapid HIV tests were used for parents. Both parents' consent was required according to the Ivorian Ethical Committee to perform a HIV test on HIV-exposed children. Free HIV care was offered to those who were diagnosed HIV-infected. FINDINGS: We provided 3,013 HIV tests for infants and their 2,986 mothers. While 1,731 mothers (58% accepted the principle of EID, only 447 infants had formal parental consent 15%; 95% confidence interval (CI: [14%-16%]. Overall, 1,817 mothers (61% accepted to test for HIV, of whom 81 were HIV-infected (4.5%; 95% CI: [3.5%-5.4%]. Among the 81 HIV-exposed children, 42 (52% had provided parental consent and were tested: five were HIV-infected (11.9%; 95% CI: [2.1%-21.7%]. Only 46 fathers (2% came to diagnose their child. Parental acceptance of EID was strongly correlated with prenatal self-reported HIV status: HIV-infected mothers were six times more likely to provide EID parental acceptance than mothers reporting unknown or negative prenatal HIV status (aOR: 5.9; 95% CI: [3.3-10.6], p = 0.0001. CONCLUSIONS: Although the principle of EID was moderately accepted by mothers, fathers' acceptance rate remained very low. Routine HIV screening of all infants was inefficient for EID at a community level in Abidjan in 2008. Our results suggest the need of focusing on increasing the PMTCT coverage, involving fathers and tracing children issued from PMTCT programs in low HIV prevalence countries.

    Full Text Available BACKGROUND: To evaluate the type and frequency of antiretroviral drug stock-outs, and their impact on death and interruption in care among HIV-infected patients in Abidjan, Côte d'Ivoire. METHODS AND FINDINGS: We conducted a cohort study of patients who initiated combination antiretroviral therapy (cART in three adult HIV clinics between February 1, 2006 and June 1, 2007. Follow-up ended on February 1, 2008. The primary outcome was cART regimen modification, defined as at least one drug substitution, or discontinuation for at least one month due to drug stock-outs at the clinic pharmacy. The secondary outcome for patients who were on cART for at least six months was interruption in care, or death. A Cox regression model with time-dependent variables was used to assess the impact of antiretroviral drug stock-outs on interruption in care or death. Overall, 1,554 adults initiated cART and were followed for a mean of 13.2 months. During this time, 72 patients discontinued treatment and 98 modified their regimen because of drug stock-outs. Stock-outs involved nevirapine and fixed-dose combination zidovudine/lamivudine in 27% and 51% of cases. Of 1,554 patients, 839 (54% initiated cART with fixed-dose stavudine/lamivudine/nevirapine and did not face stock-outs during the study period. Among the 975 patients who were on cART for at least six months, stock-out-related cART discontinuations increased the risk of interruption in care or death (adjusted hazard ratio [HR], 2.83; 95%CI, 1.25-6.44 but cART modifications did not (adjusted HR, 1.21; 95%CI, 0.46-3.16. CONCLUSIONS: cART stock-outs affected at least 11% of population on treatment. Treatment discontinuations due to stock-outs were frequent and doubled the risk of interruption in care or death. These stock-outs did not involve the most common first-line regimen. As access to cART continues to increase in sub-Saharan Africa, first-line regimens should be standardized to decrease the probability of

    Full Text Available Parasitic infections are still of considerable public health relevance, notably among children in low- and middle-income countries. Measures to assess the magnitude of ill-health in infected individuals, however, are debated and patient-based proxies through generic health-related quality of life (HrQoL instruments are among the proposed strategies. Disability estimates based on HrQoL are still scarce and conflicting, and hence, there is a need to strengthen the current evidence-base.Between November 2011 and February 2012, a national school-based cross-sectional survey was conducted in Côte d'Ivoire. Children underwent parasitological and clinical examination to assess infection status with Plasmodium and helminth species and clinical parameters, and responded to a questionnaire interview incorporating sociodemographic characteristics, self-reported morbidity, and HrQoL. Validity analysis of the HrQoL instrument was performed, assessing floor and ceiling effects, internal consistency, and correlation with morbidity scores. Multivariate regression models were applied to identify significant associations between HrQoL and children's parasitic infection and clinical status.Parasitological examination of 4,848 children aged 5-16 years revealed Plasmodium spp., hookworm, Schistosoma haematobium, Schistosoma mansoni, Ascaris lumbricoides, and Trichuris trichiura prevalences of 75.0%, 17.2%, 5.7%, 3.7%, 1.8%, and 1.3%, respectively. Anemic children showed a significant 1-point reduction in self-rated HrQoL on a scale from 0 to 100, whereas no significant negative association between HrQoL and parasite infection was observed. The 12-item HrQoL questionnaire proofed useful, as floor and ceiling effects were negligible, internally consistent (Cronbach's alpha = 0.71, and valid, as revealed by significant negative correlations and associations with children's self-reported and clinically assessed morbidity.Our results suggest that HrQoL tools are not

    Full Text Available Handheld light microscopy using compact optics and mobile phones may improve the quality of health care in resource-constrained settings by enabling access to prompt and accurate diagnosis.Laboratory technicians were trained to operate two handheld diagnostic devices (Newton Nm1 microscope and a clip-on version of the mobile phone-based CellScope. The accuracy of these devices was compared to conventional light microscopy for the diagnosis of Schistosoma haematobium, S. mansoni, and intestinal protozoa infection in a community-based survey in rural Côte d'Ivoire. One slide of 10 ml filtered urine and a single Kato-Katz thick smear from 226 individuals were subjected to the Newton Nm1 microscope and CellScope for detection of Schistosoma eggs and compared to conventional microscopy. Additionally, 121 sodium acetate-acetic acid-formalin (SAF-fixed stool samples were examined by the Newton Nm1 microscope and compared to conventional microscopy for the diagnosis of intestinal protozoa.The prevalence of S. haematobium, S. mansoni, Giardia intestinalis, and Entamoeba histolytica/E. dispar, as determined by conventional microscopy, was 39.8%, 5.3%, 20.7%, and 4.9%, respectively. The Newton Nm1 microscope had diagnostic sensitivities for S. mansoni and S. haematobium infection of 91.7% (95% confidence interval (CI 59.8-99.6% and 81.1% (95% CI 71.2-88.3%, respectively, and specificities of 99.5% (95% CI 97.0-100% and 97.1% (95% CI 92.2-99.1%, respectively. The CellScope demonstrated sensitivities for S. mansoni and S. haematobium of 50.0% (95% CI 25.4-74.6% and 35.6% (95% CI 25.9-46.4%, respectively, and specificities of 99.5% (95% CI 97.0-100% and 100% (95% CI 86.7-100%, respectively. For G. intestinalis and E. histolytica/E. dispar, the Newton Nm1 microscope had sensitivity of 84.0% (95% CI 63.1-94.7% and 83.3% (95% CI 36.5-99.1%, respectively, and 100% specificity.Handheld diagnostic devices can be employed in community-based surveys in resource

    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

    Full Text Available BACKGROUND: Little is known about the long-term safety of infant feeding interventions aimed at reducing breast milk HIV transmission in Africa. METHODS AND FINDINGS: In 2001-2005, HIV-infected pregnant women having received in Abidjan, Côte d'Ivoire, a peripartum antiretroviral prophylaxis were presented antenatally with infant feeding interventions: either artificial feeding, or exclusive breast-feeding and then early cessation from 4 mo of age. Nutritional counseling and clinical management were provided for 2 y. Breast-milk substitutes were provided for free. The primary outcome was the occurrence of adverse health outcomes in children, defined as validated morbid events (diarrhea, acute respiratory infections, or malnutrition or severe events (hospitalization or death. Hazards ratios to compare formula-fed versus short-term breast-fed (reference children were adjusted for confounders (baseline covariates and pediatric HIV status as a time-dependant covariate. The 18-mo mortality rates were also compared to those observed in the Ditrame historical trial, which was conducted at the same sites in 1995-1998, and in which long-term breast-feeding was practiced in the absence of any specific infant feeding intervention. Of the 557 live-born children, 262 (47% were breast-fed for a median of 4 mo, whereas 295 were formula-fed. Over the 2-y follow-up period, 37% of the formula-fed and 34% of the short-term breast-fed children remained free from any adverse health outcome (adjusted hazard ratio [HR]: 1.10; 95% confidence interval [CI], 0.87-1.38; p = 0.43. The 2-y probability of presenting with a severe event was the same among formula-fed (14% and short-term breast-fed children (15% (adjusted HR, 1.19; 95% CI, 0.75-1.91; p = 0.44. An overall 18-mo probability of survival of 96% was observed among both HIV-uninfected short-term and formula-fed children, which was similar to the 95% probability observed in the long-term breast-fed ones of the

  9. The Potential of Food Fortification to Add Micronutrients in Young Children and Women of Reproductive Age - Findings from a Cross-Sectional Survey in Abidjan, Cote d'Ivoire.

    Full Text Available Poor micronutrient intakes are a major contributing factor to the high burden of micronutrient deficiencies in Côte d'Ivoire. Large-scale food fortification is considered a cost-effective approach to deliver micronutrients, and fortification of salt (iodine, wheat flour (iron and folic acid, and vegetable oil (vitamin A is mandatory in Côte d'Ivoire. A cross-sectional survey on households with at least one child 6-23 months was conducted to update coverage figures with adequately fortified food vehicles in Abidjan, the capital of and largest urban community in Côte d'Ivoire, and to evaluate whether additional iron and vitamin A intake is sufficient to bear the potential to reduce micronutrient malnutrition. Information on demographics and food consumption was collected, along with samples of salt and oil. Wheat flour was sampled from bakeries and retailers residing in the selected clusters. In Abidjan, 86% and 97% of salt and vegetable oil samples, respectively, were adequately fortified, while only 32% of wheat flour samples were adequately fortified, but all samples contained some added iron. There were no major differences in additional vitamin A and iron intake between poor and non-poor households. For vitamin A in oil, the additional percentage of the recommended nutrient intake was 27% and 40% for children 6-23 months and women of reproductive age, respectively, while for iron from wheat flour, only 13% and 19% could be covered. Compared to previous estimates, coverage has remained stable for salt and wheat flour, but improved for vegetable oil. Fortification of vegetable oil clearly provides a meaningful additional amount of vitamin A. This is not currently the case for iron, due to the low fortification levels. Iron levels in wheat flour should be increased and monitored, and additional vehicles should be explored to add iron to the Ivorian diet.

    Full Text Available BACKGROUND: Evidence linking common mental disorders (CMD in pregnant women to adverse birth outcomes is inconsistent, and studies often failed to control for pregnancy complications. This study aimed to explore the association between antenatal depression and anxiety symptoms and birth outcomes in a low-obstetric risk sample of mother/child dyads in Ghana and Côte d'Ivoire. METHODS: In 2010-2011, a prospective cohort of 1030 women in their third trimester in Ghana and Côte d'Ivoire was enrolled. Depression and anxiety were assessed in the third trimester using the Patient Health Questionnaire depression module and the 7-item Generalized Anxiety Disorder scale. 719 mother/child dyads were included in the analysis. We constructed multivariate regression models to estimate the association between CMD and low birth weight (LBW, and preterm birth (PTB to control for potential confounders. RESULTS: The prevalence of depression and anxiety symptoms were 28.9% and 14.2% respectively. The mean birth weight was 3172.1g (SD 440.6 and the prevalence of LBW was 1.7%. The mean gestational age was 39.6 weeks and the proportion of PTB was 4%. Multivariate linear regression revealed no significant association between maternal depression (B=52.2, 95% CI -18.2 122.6, p=0.15 or anxiety (B=17.1, 95% CI -74.6 108.7, p=0.72 and birth weight. Yet, low socio-economic status, female sex of the child, and younger maternal age were associated with lower birth weight. Multivariate logistic regression suggested no significant association between maternal depression (OR: 2.1, 95% CI 0.8 5.6, p=0.15 or anxiety (OR: 1.8, 95% CI 0.6 5.5, p=0.29 with PTB. CONCLUSIONS: Our data suggests that depression and/or anxiety in the 3(rd trimester of pregnancy are not independent predictors of adverse birth outcomes in low obstetric risk women. The role of pregnancy complications as confounders or effect modifiers in studies of maternal CMD and their impact on birth outcomes should be

    Full Text Available Dans le foyer de maladie du sommeil de Zoukougbeu (Côte d'Ivoire, plus d'un quart des glossines capturées s'étaient gorgées sur cochon en zone de plantations, lieux préférentiels de transmission de la trypanosomose humaine. En outre, on y observe une concordance nette entre la localisation des sites où Glossina palpalis palpalis a été capturée gorgée sur ces animaux et la présence de trypanosomés. Ceci laisse penser que, dans le foyer de Zoukougbeu, mais peut-être aussi dans d'autres foyers de trypanosomose humaine africaine du secteur forestier, le cochon joue un rôle plus actif qu'on ne le pense généralement, dans la transmission de l'endémie en permettant une large diffusion du parasite par l'intermédiaire des glossines.

    Full Text Available 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.

    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.

    The susceptibility of Aedes aegypti adults of three places in Abidjan city selected for an entomological surveillance of potential arbovirus vectors to permethrin, deltamethrin, lambdacyhalothrin, and propoxur was determined using WHO standard procedures. The wild populations of A. aegypti were susceptible to permethrin, deltamethirn, and lambdacyhalothin. Resistance to propoxur was detected in strains collected at the Autonomous Port of Abidjan and at Koumassi (mortality rate: 77%) but possibly resistance to this insecticide at the national zoological park (mortality rate: 90.8%). Populations of the national zoological park were possibly resistant to propoxur whereas those of the Autonomous port of Abidjan and of Koumassi were resistant.

    Full Text Available This paper analyses vertical relationships between wholesale and retail prices in three local rice markets in Côte d’Ivoire. The aim of the paper is to ascertain whether the popular complaint of consumers about the asymmetric price transmission holds true. Our empirical analysis makes use of threshold cointegration and error correction models and monthly data for the period 1990-1999. We found that wholesale and retail prices are cointegrated and increases in wholesale prices are passed on to retail prices more quickly than decreases.

    This study deals with two clays referenced K1 and K2, used in the local and traditional manufacture of pottery ware at Katiola. Those samples were analysed by X-rays diffraction, infrared spectroscopy and thermal differential and chemical techniques. The results show that the samples (K1 and K2) are mainly composed of montmorillonite, kaolinite and illite. Only K1 is inter-stratified. The mineralogical balance achieved from the reflection (001) of the oriented film, indicate for K1: 74.5% of montmorillonite; 13.5% of inter-stratified clay; 7% of kaolinite and 5.4% of illite and for K2: 73.4% of montmorillonite; 23.5% of kaolinite and 3.1% of illite. The results also indicate that the raw material may not be use only for pottery. It can be consider in the protection of the environment, cosmetic industry, vegetable oil treatment, medicine etc.

    Full Text Available Background: Improving a health system requires data, but too often they are unused or under-used by decision makers. Without interventions to improve the use of data in decision making, health systems cannot meet the needs of the populations they serve. In 2008, in Côte d'Ivoire, data were largely unused in health decision-making processes. Objective: To implement and evaluate an intervention to improve the use of data in decision making in Cote d'Ivoire. Design: From 2008 to 2012, Cote d'Ivoire sought to improve the use of national health data through an intervention that broadens participation in and builds links between data collection and decision-making processes; identifies information needs; improves data quality; builds capacity to analyze, synthesize, and interpret data; and develops policies to support data use. To assess the results, a Performance of Routine Information System Management Assessment was conducted before and after the intervention using a combination of purposeful and random sampling. In 2008, the sample consisted of the central level, 12 districts, and 119 facilities, and in 2012, the sample consisted of the central level, 20 districts, and 190 health facilities. To assess data use, we developed dichotomous indicators: discussions of analysis findings, decisions taken based on the analysis, and decisions referred to upper management for action. We aggregated the indicators to generate a composite, continuous index of data use. Results: From 2008 to 2012, the district data-use score increased from 40 to 70%; the facility score remained the same – 38%. The central score is not reported, because of a methodological difference in the two assessments. Conclusions: The intervention improved the use of data in decision making at the district level in Côte d'Ivoire. This study provides an example of, and guidance for, implementing a large-scale intervention to improve data-informed decision making.

    Few countries in sub-Saharan Africa make systematic searches for antigens C, c, E, and e of the Rh and Kell system antigens in the donor and recipient, thereby exposing transfused patients. Purpose and Objectives. In this paper, we propose to determine the red cell Rh and Kell blood groups among blood donors from traditional techniques to improve medical care of transfused patients. This study will allow us to assess the frequency of blood group antigens in these systems. Study Design and Methods. We carried out a study on the red cell typing in the blood donor population of the National Blood Transfusion Center in Abidjan. This study was performed on 651 blood donors. Results. For the Rh system, the antigen frequencies of D, c, e, C, and E are, respectively, 92.93%, 99.85%, 99.85%, 21.97%, and 13.82%. K antigen is found in 0.77% of donors. Discussion and Conclusion. Although the frequencies of the most immunogenic antigens are lower than in the white race, lack of preventive measures makes the immunological risk high in Africa. Furthermore, Africa is full of specificities that are important to note for a better care of our patients. PMID:25328758

    Within the framework of its strategic goal of vaccine coverage (VC) improvement, GAVI, The Vaccine Alliance has entrusted the Agence de médecine préventive (agency for preventive medicine, AMP) with technical assistance services to Cameroon, Cote d'Ivoire (Ivory Coast), and Mauritania. This support was provided to selected priority districts (PDs) with the worst Penta3 coverage performances. In 2014, PDs benefited from technical and management capacities in vaccinology strengthening for district medical officers, supportive supervisions and technical assistance in health logistics, data management and quality. We analyzed the effects of the AMP technical assistance on the improvement of the cumulative Penta3 coverage, which is the key performance indicator of the expanded programme on immunization (EPI) performance. We compared Penta3 coverage between PDs and other non-priority districts (NPDs), Penta3 coverage evolution within each PD, and the distribution of PDs and NPDs according to Penta3 coverage category between January and December 2014. Technical assistance had a positive effect on the EPI performance. Indeed Penta3 coverage progression was higher in PDs than in NPDs throughout the period. Besides, between January and December 2014, the Penta3 VC increased in 70%, 100% and 86% of DPs in Cameroon, Côte d'Ivoire and Mauritania, respectively. Furthermore, the increase in the number of PDs with a Penta3 coverage over 80% was higher in DPs than in NPDs: 20% versus 8% for Cameroon, 58% versus 29% for Côte d'Ivoire and 17% versus 8% for Mauritania. Despite positive and encouraging results, this technical assistance service can be improved and efforts are needed to ensure that all health districts have a VC above 80% for all EPI vaccines. The current challenge is for African countries to mobilize resources for maintaining the knowledge and benefits and scaling such interventions in the public health area.

    2005-01-01

    Objective We assessed the uptake of a nutritional intervention promoting exclusive breastfeeding with early cessation between three and four months of age to reduce postnatal transmission of HIV in Abidjan, Côte d’Ivoire. Design Between March 2001 and March 2003, HIV infected pregnant women who had received a perinatal antiretroviral prophylaxis were systematically offered prenatally two infant feeding interventions: either artificial feeding, or exclusive breastfeeding during three months then early cessation of breastfeeding. Mother-infant pairs were closely followed for a period of two years, with continuous nutritional counseling and detailed collection of feeding practices. Results Among the 557 mothers enrolled, 262 (47%) initiated breastfeeding. Of these women, the probability of practicing exclusive breastfeeding from birth was 18% and 10% at one and three months of age, respectively. Complete cessation of breastfeeding was obtained in 45% and 63% by four and six months of age, respectively. Environmental factors such as living with partner’s family were associated with failure to initiate early cessation of breastfeeding. Conclusions Acceptability of exclusive breastfeeding was low in this urban population. However, shortening the duration of breastfeeding appeared to be feasible. Further investigations are ongoing to fully evaluate the safety and effectiveness of this intervention in reducing breastmilk HIV transmission. PMID:16284538

    Full Text Available OBJECTIVE: To assess the performance of QuantiFERON-TB Gold In-Tube (QFT-GIT test for active tuberculosis (TB in HIV adults, and its variation over time in patients on antiretroviral therapy (ART and/or isoniazide preventive therapy (IPT. METHODS: Transversal study and cohort nested in the Temprano ANRS 12136 randomized controlled trial assessing benefits of initiating ART earlier than currently recommended by World Health Organization, with or without a 6-month IPT. Performance of QFT-GIT for detecting active TB at baseline in the first 50% participants, and 12-month incidence of conversion/reversion in the first 25% participants were assessed. QFT-GIT threshold for positivity was 0.35 IU/ml. RESULTS: Among the 975 first participants (median baseline CD4 count 383/mm3, positive QFT-GIT test 35%, 2.7% had active TB at baseline. QFT-GIT sensitivity, specificity, positive and negative predictive value for active TB were 88.0%, 66.6%, 6.5% and 99.5%. For the 444 patients with a second test at 12 months, rates for conversion and reversion were 9.3% and 14%. Reversion was more frequent in patients without ART and younger patients. IPT and early ART were not associated with reversion/conversion. CONCLUSION: A negative QFT-GIT could rule out active TB in HIV-infected adults not severely immunosuppressed, thus avoiding repeated TB testing and accelerating diagnosis and care for other diseases.

    Full Text Available Buruli ulcer (BU is a cutaneous infectious disease caused by Mycobacterium ulcerans. The exact mode of transmission remains elusive; yet, some studies identified environmental, socio-sanitary, and behavioral risk factors. The purpose of this study was to assess the association of such factors to contracting BU in Tiassalé, south Côte d'Ivoire.A case-control study was conducted in 2012. Cases were BU patients diagnosed according to clinical definition put forth by the World Health Organization, readily confirmed by IS2404 polymerase chain reaction (PCR analysis prior to our study and recruited at one of the health centers of the district. Two controls were matched for each control, by age group (to the nearest 5 years, sex, and living community. Participants were interviewed after providing oral witnessed consent, assessing behavioral, environmental, and socio-sanitary factors.A total of 51 incident and prevalent cases and 102 controls were enrolled. Sex ratio (male:female was 0.9. Median age was 25 years (range: 5-70 years. Regular contact with unprotected surface water (adjusted odds ratio (aOR = 6.5; 95% confidence interval (CI = 2.1-19.7 and absence of protective equipment during agricultural activities (aOR = 18.5, 95% CI = 5.2-66.7 were identified as the main factors associated with the risk of contracting BU. Etiologic fractions among exposed to both factors were 84.9% and 94.6%, respectively. Good knowledge about the risks that may result in BU (aOR = 0.3, 95% CI = 0.1-0.8 and perception about the disease causes (aOR = 0.1, 95% CI = 0.02-0.3 showed protection against BU with a respective preventive fraction of 70% and 90%.Main risk factors identified in this study were the contact with unprotected water bodies through daily activities and the absence of protective equipment during agricultural activities. An effective strategy to reduce the incidence of BU should involve compliance with protective equipment during agricultural activities and avoidance of contact with surface water and community capacity building through training and sensitization.

    2011-06-15

    This paper examines the causal relationship between the electric power industry and the economic growth of Cote d'Ivoire. Using the data from 1971 to 2008, a test was conducted for the cointegration and Granger causality within an error correction model. Results from these tests reveal a bidirectional causality between per capita electricity consumption and per capita GDP. A unidirectional causality running from electricity consumption to industry value added appears in the short run. Economic growth is found to have great effects on electricity consumption and a reverse causality from electricity to economic growth may also appear. In the long run, there is a unidirectional causality between electricity and both GDP and industry value added. From these findings, we conclude that the country will be energy dependent in the long run and must therefore secure the production network from shortfalls to ensure a sustainable development path. Accordingly, government should adopt policies aimed at increasing the investment in the sector by stepping up electricity production from existing and new energy sources. - Highlights: > We analyze the electricity-growth nexus for Cote d'Ivoire using causality tests. > Short run bi-directional causality appears between electricity and GDP. > We found a unidirectional causality running from electricity to industry and GDP. > Economic activities are electricity dependent and require appropriate policies.

  8. Finding optimal step of fuzzy Newton-Cotes integration rules by using the CESTAC method

    Full Text Available The aim of this work, is to evaluate the value of a fuzzy integral by applying the Newton-Cotes integration rules via a reliable scheme. In order to perform the numerical examples, the CADNA (Control of Accuracy and Debugging for Numerical Applications library and the CESTAC (Controle et Estimation Stochastique des Arrondis de Calculs method are applied based on the stochastic arithmetic. By using this method, the optimal number of points in the fuzzy numerical integration rules and the optimal approximate solution are obtained. Also, the accuracy of the fuzzy quadrature rules are discussed. An algorithm is given to illustrate the implementation of the method. In this case, the termination criterion is considered as the Hausdorff distance between two sequential results to be an informatical zero. Two sample fuzzy integrals are evaluated based on the proposed algorithm to show the importance and advantage of using the stochastic arithmetic in place of the floating-point arithmetic.

    Breast cancer in men is rare, and clinical trials are thus not feasible. This study aimed to describe the epidemiological characteristics, treatment and prognostic factors of breast cancer in men. A population-based study was performed using data from the Cote d'Or breast and gynaecological cancer registry. Data on male breast cancer diagnosed from 1982 to 2008 were provided. Relative survival rates were estimated at 5 years according to the characteristics of the patient and tumour, and treatment. Prognostic factors of survival in men with breast cancer were identified using a generalised linear model. Seventy-five men with invasive breast cancer were registered. Mean age at diagnosis was 66 years. The use of adjuvant chemotherapy (P= 0.013) and hormone therapy (P Male breast cancer is a rare disease with a poor prognosis, and diagnosis is often made at an advanced stage. Early diagnosis and better knowledge of the disease would certainly lead to improvements in the prognosis. © 2012 Blackwell Publishing Ltd.

    Full Text Available This study analyzed the relationship between the current account balance of the balance of payment and its determinants for the periods 1978 to 2008 in Nigeria, Ghana and Cote d’ Ivoire. The analysis was based on the saving-investment theory and also in line with the intertemporal approach. Using a linear Vector Autoregressive (VAR approach, our results show that all the variables, except the relative income (RELY, real effective exchange rate (REER and domestic investment (INV for Nigeria, Ghana and Cote’d’Ivoire respectively are important in explaining the long run relationship. However, there was no evidence of short run relationship between the variables and the current account balance in all the three countries. The presence of long run co-movements between the current account balance and its determinants found in this study implies the effectiveness of targeting one of the variables in influencing the long run behaviour of the other variables. The current account imbalance observed in our selected countries was unavoidable and reflected the complexity of the economic problems the countries faced during these years.

    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.

    The frequency of resistance mutations was estimated in the cohort of Agence Nationale de Recherches sur le SIDA Ditrame Plus, a study that evaluated the combination of short-course zidovudine (ZDV) plus lamivudine (3TC) and single-dose nevirapine (SD-NVP) followed by 3 days of postpartum ZDV plus 3TC for the prevention of mother-to-child transmission of human immunodeficiency virus type 1 (HIV-1). The frequency with which resistance mutations were detected in mothers at week 4 postpartum was 1.14% (95% confidence interval [CI], 0.03%-6.17%) for NVP and 8.33% (95% CI, 3.66%-15.76%) for 3TC. In multivariate analysis, 3TC resistance was associated with a longer duration of ZDV plus 3TC prepartum prophylaxis (P=.009). This regimen, which is feasible in resource-limited settings, prevents most peripartum HIV-1 transmission and minimizes the development of NVP resistance.

    In Abidjan, Côte d'Ivoire, 18% of men who have sex with men (MSM) are HIV-positive. Based on ethnographic research conducted among HIV peer educators and activists in Abidjan, I examine their narratives and hand-drawn maps of city space. I draw on a methodological process of map-making to examine research participants' evaluations of neighborhoods and link these evaluations to debates over national and cultural belonging in Côte d'Ivoire. I suggest a moral geography emerges from the maps and narratives and ask what the bioethical implications of moral geography are in the context of service delivery and activism among sexual minorities.

    Polycrystalline NiSe, NiTe, CoSe, and CoTe have been synthesized by two methods, i.e., (1) the solid-state reaction in an evacuated quartz ampoule (QA) and (2) the high-pressure (HP) technique (HP) in a Au capsule using a cubic anvil cell. All the obtained samples have the nickel arsenide-type hexagonal crystal structure, except CoTe (HP), and their estimated lattice parameters, a and c, show almost the same values within 0.8% in comparison between samples prepared by the QA method and those by the HP method. On the other hand, a distinct difference between samples prepared by QA and HP processes is found in the magnetization of NiSe and NiTe. In particular, for NiTe, the temperature dependence of magnetization indicates two transition temperatures at about 20 and 130 K in samples prepared by the HP process. However, samples of NiTex (x = 0.5, 0.66, 0.82, 1, 1.22, and 2) and NiTe containing Au prepared by QA process do not show similar magnetic orders in the temperature range between 2 and 300 K. Also, samples of NiSe (HP) show magnetic transition at ˜20 K, while those of NiSe (QA) show a magnetic inflection point at ˜10 K. To the best of our knowledge the remarkable difference in magnetic properties caused by the method of synthesis has not been reported. In this paper, we present comparative experimental results of magnetic, electric, and specific heat measurements of samples prepared by the two methods. A possible explanation for such a substantial difference in magnetic interaction will be discussed.

    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.

    After the adoption of the Global Initiative for Measles Elimination in 2001, Côte d'Ivoire has created monitoring case by case. Thus, the diagnosis of measles from the gingival fluid was implemented, through a pilot project. This study aimed to evaluate the performance of this diagnostic test. We conducted a cross-sectional survey, in four health districts of Abidjan, during a period from July 2010 to December 2012. The study consisted in collecting gingival fluid and serum samples in all suspected measles children. These samples were analyzed by ELISA test at Pasteur Institute of Côte d'Ivoire. Standard formulas were used to calculate sensitivity, specificity, positive predictive value and negative predictive value of oral fluid compared to serum taken as the "gold standard" and confidence intervals were estimated with error alpha risk (α =0.05). The concordance of kappa coefficient (k) was used to estimate agreement level between the results of oral fluid analysis and those of serum. The sensitivity and specificity of the test were 98% and 82% respectively while the positive predictive value and the negative predictive value were 84% and 98%. The comparison of oral fluid with the reference test showed high agreement, between 0.61 and 0.80. The diagnostic test on gingival fluid is acceptable because its sensitivity, specificity and negative predictive value had high level. Therefore it can be extended to all sanitary districts.

  7. Ten years of limnological monitoring of a modified natural lake in the tropics: Cote Lake, Costa Rica.

    It is located 650m above sea level along the boundary between the North Caribbean and Pacific slopes, near the Southern end of the volcanic Guanacaste mountain range. In the early 1980s the lake's main outlet was dammed and the outflow was diverted into Arenal Reservoir. Lake Cote was first studied in 1990-1991, and later in 2001, before it was again modified by raising its dam by one meter to use its outflow for hydroelectricity. From 2002 to 2010 it has been monitored twice a year for changes in its limnology. Here I present a summary of its basic characteristics and an analysis of their changes through time. The lake is discontinuous polymictic, and sometimes develops a thermocline at 6m depth that may last for several days as evidenced by the occasional development of an anoxic layer close to the bottom. Since its modification for hydropower production, the surface water temperature has attained higher values than before. Oxygen levels in the lake show periods of hypoxia to anoxia in the hypolimnion, that have become more frequent since modification. Despite its turbid water, the lake has low levels of nutrient concentrations and of chlorophyll a. The trend in these parameters in recent times is a reduction in chlorophyll a and an increase in water transparency, implying a reduction in primary productivity. These changes are discussed in relationship with anthropogenic factors such as the modification of the lake and its management, changes in landscape around the lake and global climate change.

  8. Developpement D'un Modele Climatique Regional: Fizr Simulation des Conditions de Janvier de la Cote Ouest Nord Americaine

    1995-11-01

    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

    Introduction. The characterization of genetic profile of Plasmodium isolates from different areas could help in better strategies for malaria elimination. This study aimed to compare P. falciparum diversity in two African countries. Methods. Isolates collected from 100 and 73 falciparum malaria infections in sites of Côte d'Ivoire (West Africa) and Gabon (Central Africa), respectively, were analyzed by a nested PCR amplification of msp1 and msp2 genes. Results. The K1 allelic family was widespread in Côte d'Ivoire (64.6%) and in Gabon (56.6%). For msp2, the 3D7 alleles were more prevalent (>70% in both countries) compared to FC27 alleles. In Côte d'Ivoire, the frequencies of multiple infections with msp1 (45.1%) and msp2 (40.3%) were higher than those found for isolates from Gabon, that is, 30.2% with msp1 and 31.4% with msp2. The overall complexity of infection was 1.66 (SD = 0.79) in Côte d'Ivoire and 1.58 (SD = 0.83) in Gabon. It decreased with age in Côte d'Ivoire in contrast to Gabon. Conclusion. Differences observed in some allelic families and in complexity profile may suggest an impact of epidemiological facies as well as immunological response on genetic variability of P. falciparum.

    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.

    Some 84,000 children with HIV/AIDS live in Côte d'Ivoire, where very little therapeutic or psychological help is available to them. The Yopougon Child Programme of the "Agence Nationale de Recherche sur le Sida" was launched in Abidjan in October 2000. It provides services for HIV-infected children and psychological consultations for children and their parents. This paper is about the psychosexual development of the HIV-positive adolescents in the Programme, 11 girls and 8 boys aged 13-17, their problems with HIV-related physiological and psychosexual changes, and relationships with their parents. The information was gathered in individual therapy sessions, group discussions and family support sessions. Bodily development was of major importance to these adolescents, particularly among those who had not yet developed secondary sexual characteristics and were shorter and weighed less than their peers. Those who had not achieved puberty were unable to participate in traditional rituals and worried whether they could ever marry or have children. In most cases, adolescents with HIV have been infected by a sexually transmitted virus without having had sexual relations themselves. They need support dealing with their sexual development and sexual feelings, along with medical care, in a context in which HIV infection is a secret, impossible to talk about with their peers.

  13. Characterization and Dynamics of Agrarian Structures in Bouna, Northeast of Côte d'Ivoire

    2013-06-01

    Full Text Available In order to better reproduction of the information that is as close as possible to reality, we have established a procedure for analyzing images based on visual interpretation and digital processing. In digital processing, supervised classification by maximum likelihood, based on a fieldwork allowed to discriminate elements of land. Recovery of geometric shapes by scanning fallow and bare soil from panchromatic Spot image yielded the map of agrarian structures. Different queries and statistical operations performed were used to assess the areas of agrarian structures. The analysis of the dynamics of agrarian structures showed that the period 1986 - 2000 was marked by environmental degradation, while the period 2000 - 2004 has seen a regeneration of the natural environment. Treatments applied to images and ensuing results indicate the feasibility of monitoring by remote sensing of agricultural structures in northeastern area of Côte d'Ivoire. This research shows that the Geographic Information System is an effective tool for the evaluation of agrarian structures. However, manual scanning of elements in the environment requires careful attention to avoid skewing the results.

    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.

    The District of Abidjan, located on the coastal sedimentary basin south of Côte d'Ivoire (West Africa) covers an area of 2,1 km2. This sedimentary basin is composed of continuous groundwater aquifers in Quaternary, Tertiary and Upper Cretaceous rocks. Our study focuses on the unconfined Quaternary groundwater called the Continental Terminal which formations are composed mainly of lenticular stratification of coarse sands, clays, ferruginous sandstone and iron ore. This Continental Terminal aquifer is the main source of drinking water for the city of Abidjan. Indeed, the city of Abidjan is facing various pollution problems such as illegal dumping of household waste, waste oils garages, domestic and industrial wastewater, gas stations, public discharge Akouédo and the spill of approximately 500 tons of toxic waste from the ship "Probo Koala" the night of 19 August 2006. These toxic wastes have killed more than 10 people and several infections. The infiltration of these contaminants under the influence of rainwater in the basement is a serious threat to groundwater from the District of Abidjan especially as the rains are very strong in this part of the country. What would be the fate of pollutants such as organochlorines, hydrogen sulfide, sulfides and hydrocarbons contained in toxic waste, knowing that this aquifer is the main source of supply of drinking water to the city of Abidjan? It therefore seems necessary to study the vulnerability of groundwater of Abidjan District. The overall objective of this study is to assess the risk of groundwater contamination by organochlorines, sulfides, hydrogen sulfide and hydrocarbons. This project is to develop groundwater flow and contaminant transport models such as organochlorines models, hydrogen sulfide and sulfides with two digital codes, Visual Modflow and Feflow. Then several scenarios with different pollutants are finally made to realize maps of groundwater vulnerability from Abidjan to these contaminants.

    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.

    The authors used computed tomography (CT) to assess and categorize the topography of ischemic strokes (IS) among blacks living in Abidjan, the commercial and administrative center of Côte d'Ivoire, in West Africa. This retrospective study analyzed CT data of patients admitted to the Sainte Anne Marie Polyclinic (the principal private hospital in the country) and to the neurology department of the university hospital center in Cocody, from January 1, 2000, to December 31, 2001. The study included patients who met World Health Organisation criteria for stroke and had CT performed during the hospitalization for this stroke. We examined CT data to find early and late signs of IS, analyze lesion diameter (15 mm cutoff used to distinguish infarcts from lacuna), and determine their topography (cerebral arterial territory and localization, that is, brain lobes, basal ganglia and posterior cerebral fossa). We included 260 subjects (58% males) with a median age of 45 years (range: 20-80 years). CT findings were abnormal for 224 patients with infarcts (72.7%), lacuna (27.3%), or both (8%). As reported elsewhere, the anterior arterial territory was most often affected (83.9%) with a middle cerebral artery lesion in 79.4% of patients. Posterior territory (16.1%) lesions and lacuna were probably underestimated because CT exploration is reported to be less useful for this area than for the carotid area. On the other hand, CT diagnoses infarcts more easily than it does lacuna. CT was normal for 36 patients although performed no more than 3 days after IS. These patients did not undergo CT angiography, which might have shown cerebral artery occlusion. Our study included IS of all types and typography. Stroke registries in Africa would provide useful data for better assessment of prevalence for specific topographic and etiologic types of stroke.

    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.

    The use of plants during pregnancy is a common practice in Africa. In Côte d'Ivoire, despite modern antenatal medical prescriptions, most pregnant women resort to traditional medicine to ensure foetus development and facilitate childbirth. Yet, there is not enough research on the African traditional medicine concerning this aspect of health. Therefore, the plants used by pregnant women need to be better known in order to offer integrated antenatal care. This study analyzes the salience of plants used, the associated practices and reasons of such practices by pregnant women in Yakassé-Féyassé, an Anyi-Ndenye town of the Eastern Côte d'Ivoire. Methods include an ethnobotany survey (freelist method, interview with pregnant women during their antenatal consultation and with specialists). The survey led to a list of 75 plants distributed in 3 class of salience. In addition, 90.3 % of pregnant women use these practices which are nevertheless ignored by Midwives during antenatal visits.

    Osteonecrosis is the most frequent complications of sickle-cell disease (S.C.D.) whose prevalence in Cote d'Ivoire is 21%. The main of this study was to compare scintigraphy, clinical and radiological observations to assess earlier diagnosis in S.C.D. osteonecrosis. It was a prospective study about 45 S.C.D. patients who presented coxopathy and had radio-labelled di phosphonates bone scintigraphy. The results revealed 49% of lesions whose 48% appeared with homogeneous hyper fixation, 11% homogeneous hypo fixation, 5% of hypo fixation got round by hyper fixation. Eighty-one percent of lesions concerned femoral head, 6% femoral condyle and 3% humoral head. Fifty percent of osteonecrosis was not visible in radiology and corresponded to the earlier stage. These invisible radiology aspects were observed in 100% hips without lameness, and in 43% permanent lameness. Scintigraphy (sensitive in 100%) isolated 38% more than conventional radiography. In main to improve S.C.D. osteonecrosis prognostic in Cote d'Ivoire, this preliminary study outline that scintigraphy is fundamental in management. (authors)

    Full Text Available Abstract Recently identified hantaviruses harbored by shrews and moles (order Soricomorpha suggest that other mammals having shared ancestry may serve as reservoirs. To investigate this possibility, archival tissues from 213 insectivorous bats (order Chiroptera were analyzed for hantavirus RNA by RT-PCR. Following numerous failed attempts, hantavirus RNA was detected in ethanol-fixed liver tissue from two banana pipistrelles (Neoromicia nanus, captured near Mouyassué village in Côte d'Ivoire, West Africa, in June 2011. Phylogenetic analysis of partial L-segment sequences using maximum-likelihood and Bayesian methods revealed that the newfound hantavirus, designated Mouyassué virus (MOUV, was highly divergent and basal to all other rodent- and soricomorph-borne hantaviruses, except for Nova virus in the European common mole (Talpa europaea. Full genome sequencing of MOUV and further surveys of other bat species for hantaviruses, now underway, will provide critical insights into the evolution and diversification of hantaviruses.

    This study investigated the diversity and dynamics of yeasts involved in alcoholic fermentation of a traditional sorghum beer from Côte d'Ivoire, tchapalo. A total of 240 yeast strains were isolated from fermenting sorghum wort inoculated with dry yeast from two geographic regions of Côte d'Ivoire (Abidjan and Bondoukou). Initial molecular identification to the species level was carried out using RFLP of PCR-amplified internal transcribed spacers of rDNA (ITS1-5.8S-ITS2). Ten different profiles were obtained from the restriction of PCR products with the three endonucleases HaeIII, CfoI and HinfI. Sequence analysis of the D1/D2 domain of the 26S rDNA and the ACT1 gene allowed us to assign these groups to six different species: Saccharomyces cerevisiae-like, Candida tropicalis, Pichia kudriavzevii, Pichia kluyveri, Kodamaea ohmeri and Meyerozyma caribbica. The most frequent species associated with tchapalo fermentation was S. cerevisiae-like (87.36%), followed by C. tropicalis (5.45%) and M. caribbica (2.71%). S. cerevisiae-like strains were diploid heterozygotes and exhibited three to four nucleotides divergence from the type strain in the D1/D2 domain and several indels in the more discriminant sequence of the intron of the ACT1 gene. During the process, the yeast species isolated and their frequencies varied according to the geographic origin of the dry yeast. The occurrence of some species was sporadic and only two non-Saccharomyces species were found in the final product.

    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

    Full Text Available Abstract Background To improve effectiveness of malaria control interventions, it is essential to deepen the knowledge of contextual factors that govern people's practice for preventive and curative measures. The aim of this study was to determine factors that influence the use of long-lasting insecticidal nets (LLINs in three rural communities of Côte d'Ivoire, two of which benefited from recent interventions. Methods The study was carried out in 957 households in three villages (Bozi, N'Dakonankro and Yoho located in central Côte d'Ivoire. Indicators of socioeconomic position (SEP, malaria knowledge and practice, placing special emphasis on LLINs, were investigated during a cross-sectional questionnaire survey. Principal component analysis was used to calculate the SEP of households by means of a list of household assets ownership. The concentration index was used to assess the direction of the association between SEP and a given variable. To compare groups or means, Fisher's exact test, χ2 and Kruskal-Wallis test were used, as appropriate. Results Significant differences were found between SEP and reported malaria symptoms, such as fever or hot body, convulsion, anaemia and jaundice (yellow eyes. Individuals from the least poor group cited more often the use of bed nets and insecticide-treated nets (ITNs compared to poorer groups. The mean number of individuals reporting the use of bed nets and LLINs was different between groups with different educational level. Moreover, the mean number of LLINs in a household was influenced by the presence of children below five years of age. Conclusion The study not only confirmed that education and SEP play important roles in the prevention and control of malaria and promotion of health in general, but pointed at the basic essential knowledge and the key behavioural elements that should guide education and learning processes among the poorer segments of the population. In turn, such knowledge may

    In smallholder farms of Côte d'Ivoire, particularly in the northeast of the country, Cajanus cajan (pigeonpea) has become an important crop because of its multiple beneficial facets. Pigeonpea seeds provide food to make ends meet, are sold on local markets, and aerial parts serve as forage for animals. Since it fixes atmospheric nitrogen in symbiosis with soil bacteria collectively known as rhizobia, C. cajan also improves soil fertility and reduces fallow time. Yet, seed yields remain low mostly because farmers cannot afford chemical fertilizers. To identify local rhizobial strains susceptible to be used as bio-inoculants to foster pigeonpea growth, root nodules were collected in six fields of three geographically distant regions of Côte d'Ivoire. Nodule bacteria were isolated and characterized using various molecular techniques including matrix-assisted laser desorption/ionization time of flight (MALDI-TOF) mass spectrometry (MS) and DNA sequencing. These molecular analyses showed that 63 out of 85 nodule isolates belonged to two major clades of bradyrhizobia, one of which is known as the Bradyrhizobium elkanii super clade. Phylogenies of housekeeping (16S-ITS-23S, rpoB) and symbiotic (nifH) genes were not always congruent suggesting that lateral transfer of nitrogen fixation genes also contributed to define the genome of these bradyrhizobial isolates. Interestingly, no field-, plant-, or cultivar-specific effect was found to shape the profiles of symbiotic strains. In addition, nodule isolates CI-1B, CI-36E, and CI-41A that belong to distinct species, showed similar symbiotic efficiencies suggesting that any of these strains might serve as a proficient inoculant for C. cajan.

    Between 2007 and 2009, active surveys were conducted on backyard poultry (chickens, guinea fowls and ducks) in four areas of Côte d'Ivoire, including two areas where avian influenza H5N1 outbreaks occurred in 2006. Each bird underwent clinical examination. In total, 5,578 sera, 4,580 tracheal swabs and 5,120 cloacal swabs were collected, plus tissues from 35 sick chickens. Using the haemagglutination inhibition (HI) test, 277 and 36 serum samples were positive for H5 and H7, respectively; all were negative for H9. All samples were negative by reverse transcription polymerase chain reaction. These results confirm the circulation of H5 and H7 influenza subtypes in backyard poultry in Côte d'Ivoire. Given that the seropositive birds were healthy, the circulating subtypes may be low pathogenicity avian influenza strains. Half (2,680) of the sera collected from chickens were tested by HI for Newcastle disease virus (NDV) antibody: 531 were positive. The seroprevalence of 19.8% confirms the endemic status of NDV, but may underestimate its true prevalence in Côte d'Ivoire.

    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

    Full Text Available The practice of female genital mutilations continues to be recurrent in African communities despite the campaigns, fights, and laws to ban it. A survey was carried out in infants and young girls at the General Hospital of Abobo in Cote D’Ivoire. The purpose of the study was to describe the epidemiological aspects and clinical findings related to FGM in young patients. Four hundred nine (409 females aged from 1 to 12 years and their mothers entered the study after their consent. The results were that 60/409 patients (15% were cut. The majority of the young females came from Muslim families (97%; the earlier age at FGM procedure in patients is less than 5 years: 87%. Amongst 409 mothers, 250 women underwent FGM which had other daughters cut. Women were mainly involved in the FGM and their motivations were virginity, chastity, body cleanliness, and fear of clitoris similar to penis. Only WHO types I and II were met. If there were no incidental events occurred at the time of the procedure, the obstetrical future of these young females would be compromised. With FGM being a harmful practice, health professionals and NGOs must unite their efforts in people education to abandon the procedure.

Artesunate + amodiaquine (ASAQ and artemether-lumefantrine (AL are respectively the first- and second-line treatments for uncomplicated falciparum malaria in Côte d'Ivoire. A comparison of the efficacy and safety of these two drug combinations was necessary to make evidence-based drug treatment policies. Methods: In an open-label, non inferiority, randomized, controlled clinical trial, children aged 6–59 months were randomized to receive ASAQ or AL. Both drug regimens were given for 3 days, and follow-up was for 28 days. The primary endpoint was the 28-day cure rates and was defined as proportion of patients with polymerase chain reaction (PCR-corrected cure rate after 28 days of follow-up. Findings: A total of 251 patients who were attending the Ayame and Dabakala hospitals and presenting with symptomatic acute uncomplicated falciparum malaria were randomized to receive ASAQ (128 and AL (123. The intention-to-treat analysis showed effectiveness rates of 94.5% and 93.5% for ASAQ and AL, respectively on day 28. After adjustment for PCR results, these rates were 96.1% and 96.8%, respectively. On day 28, the per-protocol analysis showed effectiveness rates of 98.4% and 96.6% for ASAQ and AL, respectively. After adjustment by PCR for reinfection, these rates were 100% for each drug, and both regimens were well tolerated. Conclusion: ASAQ and AL remain efficacious treatments of uncomplicated falciparum malaria in Ivorian children 5 years after adoption. The efficacy of ASAQ and AL in Côte d'Ivoire requires, therefore, continuous

    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 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.

    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.

    We performed HIV-1 drug resistance genotypic analysis of viral isolates from 100 antiretroviral (ARV)-naive, recently HIV-1-infected (between 2002 and 2006) individuals from Abidjan (Côte d'Ivoire). The overall prevalence of HIV-1 variants with resistance mutations to reverse transcriptase, protease, or fusion inhibitors was 6%. The majority of isolates were CRF02_AG. Compared with a previous study carried out by our group in 2001-2002 in a similar population in Abidjan, our findings confirm the circulation and transmission of HIV-1 carrying key ARV drug resistance mutation.

    Soil-transmitted helminthiasis affects more than a billion people in the world and accounts for a global burden of 5.1 million disability-adjusted life years. The objectives of this study were (i) to map and predict the risk of soil-transmitted helminth infections among school-aged children in Côte d'Ivoire; (ii) to estimate school-aged children population-adjusted risk; and (iii) to estimate annual needs for preventive chemotherapy. In late 2011/early 2012, a cross-sectional survey was carried out among school-aged children in 92 localities of Côte d'Ivoire. Children provided a single stool sample that was subjected to duplicate Kato-Katz thick smears for the diagnosis of soil-transmitted helminths. A Bayesian geostatistical variable selection approach was employed to identify environmental and socioeconomic risk factors for soil-transmitted helminth infections. Bayesian kriging was used to predict soil-transmitted helminth infections on a grid of 1 × 1 km spatial resolution. The number of school-aged children infected with soil-transmitted helminths and the amount of doses needed for preventive chemotherapy according to World Health Organization guidelines were estimated. Parasitological data were available from 5246 children aged 5-16 years. Helminth infections with hookworm were predominant (17.2 %). Ascaris lumbricoides and Trichuris trichiura were rarely found; overall prevalences were 1.9 % and 1.2 %, respectively. Bayesian geostatistical variable selection identified rural setting for hookworm, soil acidity and soil moisture for A. lumbricoides, and rainfall coefficient of variation for T. trichiura as main predictors of infection. The estimated school-aged children population-adjusted risk of soil-transmitted helminth infection in Côte d'Ivoire is 15.5 % (95 % confidence interval: 14.2-17.0 %). We estimate that approximately 1.3 million doses of albendazole or mebendazole are required for school-based preventive chemotherapy, and we provide school

    Background 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. Methods 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. Results 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. Conclusion 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

    The FonSIDA is a private clinic created in 1992 within the premises of the National Blood Transfusion Center of Abidjan (CNTS), the largest city in Côte d'Ivoire. It provides medical and psychological follow-up for blood donors which are diagnosed as HIV-infected. This Centre provides blood for transfusions in Abidjan and the surrounding area, which from 1992 to 1999 collected 263,398 blood units. In this period, 5574 subjects were detected HIV-positive. Among those, 1766 (32%) HIV infected blood donors came back to be tested for confirmation of HIV diagnosis. Since then, only 9% of the 5574 donors have been seen at least twice a year for medical and psychological follow-up. Women were more compliant than men in the FonSIDA Clinic: they constituted 62% of the 409 patients who were followed-up (p < 0.001). 53% of men had sex with prostitutes the year before HIV diagnosis. 67% of women stated voluntary abortion at least once. In the same period the systematic use of condoms was reported by only 7% of women and 5% of men. 22% of women and 28% of men reported having two or more sexual partners in the year before HIV diagnosis. The main aim of every blood center is to improve blood safety, particularly in developing countries. The appropriate counseling towards blood donors and especially those detected HIV positive can contribute to reduce new HIV infections in high HIV prevalence cities. Rate of compliance of HIV-infected patients to follow-up has risen to 11% in 1992-1994 to 60% in 1997-1999 and will contribute to reach this aim.

    The aim of this study was to evaluate the prevalence of Clostridium difficile and Clostridium perfringens in cooked beef sold in the streets in Côte d'Ivoire and their antimicrobial susceptibility. A total of 395 kidney and flesh samples of cooked beef were collected from vendors at Abidjan and subjected to C. difficile and C. perfringens isolation and identification by using biochemical tests, API 20A system and PCR detection. Subsequently, the antimicrobial susceptibility test was performed for confirmed isolates. Our results showed the prevalence of 12.4% for C. difficile (11.04% in kidney and 13.45% in flesh) and 5.06% for C. perfringens (2.32% in kidney and 7.17% in flesh). Metronidazole and vancomycin remained the most potent antimicrobial agents against C. difficile while metronidazole and penicillin G were the most potent agents against C. perfringens. The resistance rates to tetracycline, doxycycline, chloramphenicol and erythromycin against C. difficile and C. perfringens isolates ranged from 2.05% to 8.16% and from 20% to 50%, respectively. Among all antimicrobial agents tested against C. difficile, percentages of resistance to quinolones ciprofloxacin, norfloxacin and nalidixic acid as well as to gentamicin and cefotaxime were the highest. Eight resistant phenotypes were defined for C. difficile isolates and eleven resistant phenotypes for C. perfringens isolates. Clindamycin/gentamicin/cefotaxime/ciprofloxacin/norfloxacin/nalidixic acid resistance was the most common phenotype for C. difficile (55.10% of isolates) while norfloxacin/nalidixic acid resistance was the most common phenotype for C. perfringens (20% of isolates).

    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 electricity in Côte d'Ivoire is mainly produced from fossil energy sources. This causes damages on environment due to greenhouse gas emissions (GHG). The aim of this paper is to calculate the greenhouse gas (GHG) emissions of jatropha oil and jatropha biodiesel as alternative fuels for electricity production in Côte d'Ivoire by using Life Cycle Assessment (LCA) methodology. The functional unit in this LCA is defined as 1 kWh of electricity produced by the combustion of jatropha oil or jatropha biodiesel in the engine of a generator. Two scenarios, called short chain and long chain, were examined in this LCA. The results show that 0.132 kg CO2 equivalent is emitted for the scenario 1 with jatropha oil as an alternative fuel against 0.6376 kg CO2 equivalent for the scenario 2 with jatropha biodiesel as an alternative fuel. An 87 % reduction of kg CO2 equivalent is observed in scenario 1 and a 37 % reduction of kg CO2 equivalent is observed in the scenario 2, when compared with a Diesel fuel.

    Based on partial env and pol (protease and RT) subtyping, we recently documented that the majority (>80%) of the HIV-1 strains that circulate in Côte d'Ivoire were CRF02_AG and about 11% were recombinants or could not be clearly assigned to a known subtype or CRF. In order to determine in more detail the precise structure of these viruses we sequenced the full-length genomes for six such strains. Bootscan and phylogenetic tree analysis showed that four strains were complex and unique CRF02_AG/CRF09_cpx recombinants, one was a CRF02_AG/CRF06_cpx recombinant, and one was a pure CRF09_cpx. Reanalysis of the remaining recombinants asserted the predominance of CRF09_cpx within intersubtype recombinants and circulation of CRF09_cpx in Côte d'Ivoire. More detailed analysis of the CRF09_cpx strains revealed also that part of the pol gene belonged to subtype K. This is the first time that such recombinants are described.

    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.

    More than 15 000 French soldiers are continuously deployed abroad. Along with combat-related injuries, they are exposed to non-combat-related diseases with an underestimated burden. Our objectives were to assess the incidence and impact of health problems on their operating capacity. A prospective multicenter study was conducted over more than three months in Lebanon, Côte d'Ivoire and Afghanistan including exclusively French soldiers. We collected 4349 consultations (Afghanistan {n = 719}, Lebanon {n = 1401} and Côte d'Ivoire {n = 2229}) encompassing 4600 health problems. Injuries (21%), diarrhea (19%), dermatoses (17.5%) and respiratory tract infections (10.45%) were the most frequent health issues. Infectious diseases represented 41% of all health problems. Almost nine out of ten patients were managed as outpatients. Ten combat-related deaths were observed. We reported 68 (1.5%) medical repatriations of which 28 and 26 were psychiatric and trauma cases respectively. Partial or complete incapacity was estimated 724 days/1000 men/month. Etiological spectrum was similar in all three countries however, the incidence of diarrhea (p < 0.05) as well as inpatient management and medical evacuation rates were higher (p < 0.0001) in Afghanistan. There was a wide spectrum of health problems occurring during military deployments with a predominance of common infections. Non-combat-related pathology represented an important burden for the loss of operating capacity. Copyright © 2014 Elsevier Ltd. All rights reserved.

    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 (P<0.0001) which corroborates with the earlier findings of Schoelynck and Struyf (2016). However, the concentrations of BSi found in Salvinia molesta (a free floating species 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.

    Full Text Available Abstract Background Sexual abstinence is the best available option for preventing both pregnancy and sexually transmitted infections, including HIV/AIDS. Identifying the factors associated with sexual abstinence among youths would have meaningful implications in a generalized HIV epidemic country such as the Côte d'Ivoire. Thus, we explored sexual abstinence behavior among never-married individuals aged 15 to 24 in Côte d'Ivoire and assessed factors that predict sexual abstinence. Methods We obtained data from the nationally representative and population-based 2005 Côte d'Ivoire AIDS Indicator Survey, conducted from September 2004 to October 2005. Our sample included 3041 never-married people aged 15 to 24. Of these, 990 reported never having sexual intercourse (primary abstinence and 137 reported sexual experience but not in the 12 months prior to the survey (secondary abstinence. In all, 1127 youths reported sexual abstinence practice. Results Of the 3041 never-married youths, 54.4% were male and 45.6% were female. About 33.0%, 6.7%, and 37.1% of them were practicing primary, secondary, and sexual abstinence behavior, respectively. Females of higher education level were significantly 11.14 times as likely as those of no education to practice either primary or secondary abstinence. Males who were animists, had no religion, or were practicing religions other than Christianity or Muslim were significantly less likely than other male youths to practice sexual abstinence (OR = 0.53, 95% CI = 0.30–0.95. Living in the north-west region of the country significantly decreased the odds of sexual abstinence among female youths. Similarly, female youths living in rural areas were significantly 0.42 times as likely as those in the urban zones to practice sexual abstinence. Conclusion HIV/AIDS prevention program components could include media campaigns, educational intervention improvement, as well as promoting policies that shape female youth

    Full Text Available Abstract Background The World Health Organization (WHO recommends using insecticide-treated mosquito nets (ITNs and intermittent preventive treatment with sulphadoxine-pyrimethamine (IPT-SP to prevent malaria in sub-Saharan Africa. Data on IPT-SP coverage and factors associated with placental malaria parasitaemia and low birth weight (LBW are scarce in Côte d'Ivoire. Methods A multicentre, cross-sectional survey was conducted in Côte d'Ivoire from March to September 2008 at six urban and semi-urban antenatal clinics. Standardized forms were used to collect the demographic information and medical histories of women and their offspring. IPT-SP coverage (≥2 doses as well as placental and congenital malaria prevalence parasitaemia were estimated. Regression logistics were used to study factors associated with placental malaria and LBW (birth weight of alive babies Results Overall, 2,044 women with a median age of 24 years were included in this study. Among them 1017 (49.8% received ≥2 doses of IPT-SP and 694 (34.0% received one dose. A total of 99 mothers (4.8% had placental malaria, and of them, four cases of congenital malaria were diagnosed. Factors that protected from maternal placental malaria parasitaemia were the use of one dose (adjusted odds ratio (aOR, 0.32; 95%CI: 0.19-0.55 or ≥2 doses IPT-SP (aOR: 0.18; 95%CI: 0.10-0.32; the use of ITNs (aOR: 0.47; 95%CI: 0.27-0.82. LBW was associated with primigravidity and placental malaria parasitaemia. Conclusion IPT-SP decreases the rate of placental malaria parasitaemia and has a strong dose effect. Despite relatively successful IPT-SP coverage in Côte d'Ivoire, substantial commitments from national authorities are urgently required for such public health campaigns. Strategies, such as providing IPT-SP free of charge and directly observing treatment, should be implemented to increase the use of IPT-SP as well as other prophylactic methods.

    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

    Human immunodeficiency virus (HIV)-associated bacillary angiomatosis has rarely been described in Africa. We report here the first case in Côte d'Ivoire. Although in industrialised countries bacillary angiomatosis has been described in patients with low CD4 count, this episode occurred in the first year following HIV-seroconversion in an adult patient with more than 500 CD4 cells per cubic millimetre. Symptoms rapidly and totally disappeared under erythromycin treatment, although with a relapse two years after the end of the first episode. In Africa where people living with HIV often present chronic cutaneous lesions, bacillary angiomatosis may be under-diagnosed. Bacillary angiomatosis must be systematically considered in face of lesions similar to Kaposi's sarcoma. Improving knowledge on symptoms of bacillary angiomatosis in Africa should lead to better treatment and a better estimation of its true frequency which may be underestimated.

    A total of 107 HIV-1 isolates from untreated adult patients recruited in Abidjan, CMte d'Ivoire, in 2001 and 2002 were sequenced in the env, reverse transcriptase (RT), and protease genes. The results show that CRF02_AG is still predominant in this west African population; key mutations of resistance to antiretroviral drugs (NRTI, NNRTI, and PIs) were detected in 5.6% of the patients. We hypothesize that these resistant mutants have been acquired through horizontal transmission. Compared to a previous study carried out by our group in 1997-2000 in a similar population of Abidjan, it seems that there is a dynamic process of resistance and that a survey will be necessary.

    Côte d'Ivoire located in West Africa, registers high level of biodiversity which occurs mainly in forest land. The country has suffered severe deforestation. However, deforestation and forest degradation release Greenhouse Gases into the atmosphere which contributes to Climate Change. In order to address the deforestation, many actions are taken, one of which is the implementation of protected areas within countries. These measures put restrictions on the access of local communities to forest services. However, local communities supplement their daily livelihood from forests, especially from timber and non-timber forest products. What are the effects of forests conservation in protected areas on surrounding population? This study focuses on the Bouaflé protected forest (foret classée de Bouaflé) in the western part of Côte d'Ivoire. The forest is 20350 ha and was made a protected forest in 1974. It is one of the most deforested protected areas in the country. Firstly, we described the perception of forest benefits by the population. Secondly, we estimated the benefits of forest conservation using a contingent valuation approach, particularly the Willingness to Pay (WTP) methodology. From our sample size of 156 households, it appears that most of the individuals are aware of the importance of the forest (94 % against 6%). According to the estimate of the benefits, it results on average, people are willing to pay 1658.491F CFA (2.53 Euros). The median WTP is 1000 FCFA. This study will be helpful by adding to the scientific literature and for inducing local people implication in conservation.

    We present the microbiological and molecular characterization of bacteria isolated from four chimpanzees and one gorilla thought to have died of an anthrax-like disease in Côte d'Ivoire and Cameroon. These isolates differed significantly from classic Bacillus anthracis by the following criteria: motility, resistance to the gamma phage, and, for isolates from Cameroon, resistance to penicillin G. A capsule was expressed not only after induction by CO2 and bicarbonate but also under normal growth conditions. Subcultivation resulted in beta-hemolytic activity and gamma phage susceptibility in some subclones, suggesting differences in gene regulation compared to classic B. anthracis. The isolates from Côte d'Ivoire and Cameroon showed slight differences in their biochemical characteristics and MICs of different antibiotics but were identical in all molecular features and sequences analyzed. PCR and Southern blot analyses confirmed the presence of both the toxin and the capsule plasmid, with sizes corresponding to the B. anthracis virulence plasmids pXO1 and pXO2. Protective antigen was expressed and secreted into the culture supernatant. The isolates possessed variants of the Ba813 marker and the SG-749 fragment differing from that of classic B. anthracis strains. Multilocus sequence typing revealed a close relationship of our atypical isolates with both classic B. anthracis strains and two uncommonly virulent Bacillus cereus and Bacillus thuringiensis isolates. We propose that the newly discovered atypical B. anthracis strains share a common ancestor with classic B. anthracis or that they emerged recently by transfer of the B. anthracis plasmids to a strain of the B. cereus group.

    Nowadays, the successful management of small scale fisheries requires the use of biometric data collected in the field, in order to transform them into suitable indicators. The present study describes the length-weight relationships for 36 freshwater fish species from two tropical reservoirs Ayame I and Buyo, in Côte d'Ivoire. The main objective of the study was to provide a length weight key for a wide range of freshwater fish species from these tropical reservoirs exploited by the inland fisheries. The samplings were carried out at Buyo from July 1997 to August 1998, and from August 2004 to July 2005 in Ayame I. Fish specimens were collected from catches of artisanal fisheries using gill-nets, cast-nets, beach seines and bamboo traps. After landings, samples were identified, total weight for each specimen was recorded to the nearest gram and standard length was measured to the nearest millimetre. A total of 12 724 individuals belonging to 15 families and 24 genera were obtained in this study. The results indicated that the family with the highest number of species was Cichlidae with eight species. Six families were recorded with only one species per family. The value of the exponent b in the length weight relationships (W=aL(b)) ranged from 2.173 for Marcusenius furcidens to 3.472 for Polypterus endlicheri and the median of b was 2.756. The modal value of the exponent b equal to 2.70 indicates that most of the fish species in Ayame I and Buyo Reservoirs have negative allometric growth. The length weight parameters of the three species, Lates niloticus, Synodontis koensis and S. punctifer are described for the first time in these regions. The present length-weight key for 36 freshwater fish species could be used as a valuable tool for fishery managers, in order to improve the inland fisheries statistics largely based on hydropower reservoirs in Côte d'Ivoire.

    The Kleine-Levin syndrome is a rare pathology characterized by recurrent episodes of hypersomnia associated with behavioral and cognitive disorders with, among others, hyperphagia and hypersexuality. The disease mainly affects young males. A few studies mention cases that occurred in Africa, especially in Côte d'Ivoire. In this paper, we report the very first two cases observed in the Neurology Department of the University Hospital of Cocody. The diagnosis was clinical, based on the recurrence of hypersomnia, cognitive and behavioral disorders during the periods of hypersomnia, and the return of patients to normal state between episodes. This diagnosis was delayed due to failure to understand the pathology, thereby leading patients to wandering. In fact, the two patients were consulted, respectively, 3 years and 6 years after the hypersomnia began. The objective was to report the very first cases observed in the Neurology Department of the University Hospital of Cocody, Côte d'Ivoire. PMID:26989535

    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

    Adolescents living with HIV are sexually active and engaged in risky sexual behaviors. Knowledge on how and to what extent adolescents in HIV care are affected by pregnancy is needed so as to adopt better preventive services. We estimated 4-year pregnancy incidence and correlates among HIV-infected female adolescents in HIV care in urban Côte d'Ivoire. We conducted retrospective analysis of a pediatric prospective cohort of the International epidemiological Databases to Evaluate AIDS (IeDEA) West Africa Collaboration. Female patients with confirmed HIV infection aged 10-19 years, having at least one clinical visit in 2009 to health facilities participating in the pediatric IeDEA West African cohort in Abidjan, Côte d'Ivoire, were included. Data on incident pregnancies were obtained through medical records and interviews with health professionals. Pregnancy incidence rate was estimated per 100 person-years (PY). Poisson regression models were used to identify factors associated with the first pregnancy and provided incidence rate ratios (IRR) with 95% confidence intervals (CI). In 2009, 266 female adolescents were included, with a median age of 12.8 years (interquartile range, IQR: 10.0-15.0), CD4 cell counts of 506 cells/mm(3) (IQR: 302-737), and 80% on antiretroviral treatment. At the 48th month, 17 new pregnancies were reported after 938 PY of follow-up: 13 girls had one pregnancy while 2 had two pregnancies. Overall incidence rate of pregnancy was 1.8/100 PY (95% CI: 1.1-2.9). High incidence was observed among those aged 15-19 years: 3.6/100 PY (95% CI: 2.2-5.9). Role of maternal death in the risk of pregnancy was at the limit of statistical significance (adjusted IRR: 3.1, 95% CI: 0.9-11.0; ref. non-maternal orphans). Incidence of pregnancy among HIV-infected adolescents in care aged 15-19 years reached a level observed in adult cohorts in Sub-Saharan Africa. Health personnel in pediatric care have to intensify their efforts to provide more realistic and age

    Full Text Available Abstract Background 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. Methods 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. Results 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

This paper presents findings from a national assessment aimed at identifying major bottlenecks in Côte d'Ivoire's PMTCT cascade, and to distinguish characteristics of high- and low-performing health facilities. Methods: This cross-sectional study, based on a nationally representative sample of 30 health facilities in Côte d'Ivoire used multiple data sources (registries, patient charts, patient booklets, interviews to determine the magnitude of LTFU in PMTCT services. A composite measure of retention – based on child prophylaxis, maternal treatment and infant testing – was used to identify high- and low-performing sites and determine significant differences using Student's t-tests. Results: Among 1,741 pregnant women newly recorded as HIV-positive between June 2011 and May 2012, 43% had a CD4 count taken, 77% received appropriate prophylaxis and 70% received prophylaxis intended for their infant. During that time, 1,054 first infant HIV tests were recorded. A conservative rate of adherence to antiretroviral therapy was estimated at 50% (n=219 patient charts.

    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 (VO2 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 VO2 max of 52.7, 53.1, 52.2, 52.6 and 55.6 ml kg−1 min−1, respectively. The VO2 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 VO2 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's physical fitness

    Objective We assessed men's and women's experiences of gender based violence and other traumatic events in Côte d'Ivoire, a West African conflict-affected setting, before, during and after a period of active armed conflict (2000–2007). Design Cross-sectional, household survey. Setting 12 rural communities directly impacted by the Crisis in Côte d'Ivoire, spanning regions controlled by government forces, rebels and UN peacekeepers in 2008. Participants 2678 men and women aged 15–49 years. Primary outcome measures Violence exposures measured since age 15. Questions included intimate partner physical and sexual violence; physical and sexual violence by others (including combatants) and exposure to traumatic events before, during and after the Crisis period (2000–2007). Results Physical and/or sexual violence since age 15 was reported by 57.1% women and 40.2% men (p=0.01); 29.9% women and 12.3% men reported exposure to any violence in the past year. Nearly 1 in 10 women (9.9%) and 5.9% men (p=0.03) were forced to have sex by a non-partner since age 15, and 14.8% women and 3.3% men (p=0.00) reported their first sexual experience was forced. Combatants were rarely reported as sexual violence perpetrators (0.3% women). After the Crisis, intimate partner physical violence was the most frequently reported form of violence and highest among women (20.9% women, 9.9% men, p=0.00). Fearing for their life was reported by men and women before, during and after the Crisis. Conclusions Sexual violence in conflict remains a critical international policy concern. However, men and women experience different types of violence before, during and after conflict. In many conflict settings, other forms of violence, including intimate partner violence, may be more widespread than conflict-related sexual violence. Alongside service provision for rape survivors, our findings underscore the need for postconflict reconstruction efforts to invest in programmes to prevent and respond to

    This study assesses factors associated with viewing of 'SIDA dans la Cite', a weekly television soap opera on AIDS in Côte d'Ivoire, and the relationship between 'SIDA dans la Cite' viewing, sexual risk behaviour and condom use. The study uses across-sectional survey of 2150 respondents aged 15-49 in three regions. Logistic regression analysis was used to assess the effect of'SIDA dans la Cite' exposure on condom use. The results show that 65% of the sample had seen at least one 'SIDA dans la Cite' episode. Among viewers, 27% of males and 41% of females had seen ten or more episodes. Persons who had risky sexual partners were particularly likely to watch the programme. Women who had seen ten or more episodes were 1.4 times more likely than non-viewers to have used a condom in last sex. Men who had seen ten or more episodes were 2. 7 times more likely to have used a condom. We conclude that television soap operas on AIDS, such as 'SIDA dans la Cite',can be an important tool for promoting condom use. The programme was most appealing to viewers who engaged in risky behaviour, who are the core transmitters of the virus. HIV prevention programmes that provide continuous information, through multiple media channels or through series of broadcasts, are likely to have the greatest impact on condom use.

    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.

    Susceptibility tests were carried out in laboratory conditions to evaluate the efficacy of alpha-cypermethrin (a synthetic pyrethroid never used in Côte d'Ivoire) for malaria vector control. Five wild populations of Anopheles gambiae originating from M'bé, Yaokoffikro, Korhogo, Kafiné and Daola and two laboratory reared strains (Kisumu susceptible and Kou permethrin resistant selected strain) were tested. The diagnostic dosage of alpha-cypermethrin for the sensitive strain Kisumu was 2.5 x 10(-3)%. A comparative study of the susceptibility of samples of wild populations of An. gambiae was carried out according to the WHO standard susceptibility test. Impregnated papers with 4% DDT, 0.25% permethrin, 0.025% deltamethrin and 0.0025% alpha-cypermethrin were used. The results showed that except for mosquitoes from M'bé, all the other populations were resistant to these insecticides. Bioassays were carried out with alpha-cypermethrin at the operational dosage of 20 mg a.i./m2 on the same population and laboratory reared strains. The results showed the efficacy of this insecticide on both the Kisumu strain and the population from M'bé, a maintained efficacy for the Daloa, Kafiné and Korhogo mosquito populations, but the wild anopheline population from Yaokoffikro clearly appeared fully resistant.

    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.

    Full Text Available A study designed to characterize the effects of shellfish products on the chemical properties of fluvisols gleyic and yield of rice was carried out in Toumbokro, Yamoussoukro’s region, Côte d'Ivoire. The work has been focused on soil amendment by three types of shells (Achatina spp Donax spp and Ostrea spp. Three doses of shellfish products (500, 1000 and 1500 kg.ha-1 and NPK fertilizer were tested in a split-plot design with three repetitions. At ground level, the study showed that the shellfish products have positive effects very marked on all the physical and chemical characteristics. The effects of these shellfish products on the richness of the soil occur gradually. The increase of pH, due to the products made, creates a condition favorable to microorganisms that become active and mineralize sufficient organic substances. The study indicates that shellfish products induce high levels of production of rice cultivation. The average of yield of the experiments carried out is set at 5.41 t.ha-1 in Toumbokro. These performances, never recorded in subsistence agriculture, are explained by the effective correction of mineral deficiencies unsuspected soil by the flow of shellfish products. All the variables studied define the contribution of 1000 kg.ha-1 shredded shells of Achatina spp, as the optimum for soil amendment.

    Elevated exposure levels to non-human primates (NHP) and NHP bushmeat represent major risk factors for zoonotic disease transmission in sub-Saharan Africa. Demography can affect personal nutritional behavior, and thus rates of contact to NHP bushmeat. Here, we analyzed demographic and NHP contact data from 504 participants of differing demographic backgrounds living in proximity to the Taï National Park in Western Côte d'Ivoire (CI) to identify factors impacting the risk of NHP exposure. Overall, participants' contact rates to NHP were high, and increased along a gradient of bushmeat processing (e.g., 7.7% hunted, but 61.9% consumed monkeys). Contact to monkeys was significantly more frequent than to chimpanzees, most likely a reflection of meat availability and hunting effort. 17.2% of participants reported previous interaction with NHP pets. Generalized linear mixed model analysis revealed significant effects of sex, country of birth or ethnicity on rates of NHP bushmeat contact, with male participants from CI being at particular risk of exposure to NHP. The presence of zoonotic pathogens in humans and NHP in Taï further highlights the risk for zoonotic disease emergence in this region. Our results are relevant for formulating prevention strategies to reduce zoonotic pathogen burden in tropical Africa.

    In the acquired immunodeficiency syndrome (AIDS) era, adequate management of sexually transmitted diseases (STDs) is a primary concern in Africa. Assessed in this study is the clinical efficacy and feasibility of WHO-recommended therapeutic algorithms for genital discharges and ulcers, diagnosed without laboratory tests, for use at the primary health care level. Drugs were sold on a cost-recovery basis and included intramuscular ceftriaxone and oral ciprofloxacin for single-dose therapy of gonorrhoea and chancroid. During April 1993 in 10 peripheral health care centres in Abidjan, Côte d'Ivoire, a total of 207 patients were followed up, including 89 cases of male urethritis, 92 cases of vaginal discharges and 26 cases of genital ulcers; clinical success, assessed 7 days after the onset of therapy, was, respectively, 92%, 87%, and 100%. Less than 10% of the 207 patients were referred to the next care level, an acceptable rate from a public health point of view. Medical adherence to the algorithms was excellent for urethral discharges and genital ulcers but poor for vaginal discharges, partly because of intentional therapeutic modifications, without detriment to success. For drugs, the average cost per cure was 1546 francs CFA (US$ 5.60) (maximum, 2980 francs CFA (US$ 10.70). Effective and affordable treatments for STDs are necessary for their realistic case management in Africa. PMID:7614662

    Twenty two distinct bacteriophages were isolated from sewage water from five locations in the city of Abidjan, Côte d'Ivoire over a two-year period, using a collection of Pseudomonas aeruginosa strains with diverse genotypes. The phages were characterized by their virulence spectrum on a panel of selected P. aeruginosa strains from cystic fibrosis patients and by whole genome sequencing. Twelve virions representing the observed diversity were visualised by electron microscopy. The combined observations showed that 17 phages, distributed into seven genera, were virulent, and that five phages were related to temperate phages belonging to three genera. Some showed similarity with known phages only at the protein level. The vast majority of the genetic variations among virulent phages from the same genus resulted from seemingly non-random horizontal transfer events, inside a population of P. aeruginosa phages with limited diversity. This suggests the existence of a single environmental reservoir or ecotype in which continuous selection is taking place. In contrast, mostly point mutations were observed among phages potentially capable of lysogenisation. This is the first study of P. aeruginosa phage diversity in an African city and it shows that a large variety of phage species can be recovered in a limited geographical site at least when different bacterial strains are used. The relative temporal and spatial stability of the Abidjan phage population might reflect equilibrium in the microbial community from which they are released.

    Portable microscopy may facilitate quality diagnostic care in resource-constrained settings. We compared a handheld light microscope (Newton Nm1) with a mobile phone attachment to conventional light microscopy for the detection of Plasmodium falciparum in a cross-sectional study in rural Côte d'Ivoire. Single Giemsa-stained thick blood film from 223 individuals were prepared and read by local laboratory technicians on both microscopes under 1,000× magnification with oil. Of the 223 samples, 162 (72.6%) were P. falciparum positive, and the overall mean parasite count was 1,392/μL of blood. Sensitivity and specificity of the handheld microscope was 80.2% (95% confidence interval [CI]: 73.1-85.9%) and 100.0% (95% CI: 92.6-100.0%), respectively, with a positive and negative predictive value of 100.0% (95% CI: 96.4-100.0%) and 65.6% (95% CI: 54.9-74.9%), respectively. If sensitivity can be improved, handheld light microscopy may become a valuable public health tool for P. falciparum diagnosis.

    People displaced by conflict who remain within the borders of their country are known as Internally Displaced Persons (IDPs). The physical and psychological health of IDPs, who have been forced to relocate to a new environment, has not been adequately studied. The objective of this study was to compare the physical and psychological health of IDPs and non-displaced populations. The study examined 580 subjects aged 18-59 years living in Côte d'Ivoire, including 290 IDPs and 290 non-displaced persons. The physical and psychological health of both groups was examined and compared using face-to-face questionnaires. The prevalence of physical illness and depression and anxiety disorders were found to be twice as high among IDPs (80% compared to 42% and 60% compared to 30%). This study provides evidence of the high prevalence of physical and psychological morbidity among IDPs. The results highlight the importance of providing better support to this highly vulnerable population.

    Group living animals can exhibit fission-fusion behavior whereby individuals temporarily separate to reduce the costs of living in large groups. Primates living in groups with fission-fusion dynamics face numerous challenges in maintaining spatial cohesion, especially in environments with limited visibility. Here we investigated the spatial cohesion of adult male chimpanzees (Pan troglodytes verus) living in Taï National Park, Côte d'Ivoire, to better understand the mechanisms by which individuals maintain group cohesion during fission-fusion events. Over a 3-year period, we simultaneously tracked the movements of 2-4 males for 4-12 hr on up to 12 consecutive days using handheld GPS devices that recorded locations at one-minute intervals. Analyses of the male's inter-individual distance (IID) showed that the maximum, median, and mean IID values across all observations were 7.2 km, 73 m, and 483 m, respectively. These males (a) had maximum daily IID values below the limits of auditory communication (cohesion when out of sight, and that auditory communication is one likely mechanism by which they do so. We discuss mechanisms by which chimpanzees may maintain the level of cohesion observed. This study provides a first analysis of spatial group cohesion over large distances in forest chimpanzees using high-resolution tracking, and illustrates the utility of such data for quantifying socio-ecological processes in primate ecology.

    Full Text Available A study of the physico chemical properties of gleyic Luvisols and gleyic Histosols was carried on in Nieki Valley, a vegetable crops production area in South-East of Côte d'Ivoire. Soil samples were collected at different depths (0-15 cm and 15-40 cm on each of the sites studied for laboratory analysis. The results obtained of physical analysis show that the texture of soil is generally less thin and essentially provided in heavy clays. The observed average values of the index of crusting and the ability to cracking show that soils are not crusting and have an excellent ability to cracking. The results of physical analysis also show that the soils have an index of structural stability that change from very stable to stable and a very high risk of asphyxiation. Results of chemical analysis reveal that the pH values increased with soil depth and are higher in field soils than in control soils. Moreover, organic matter in soils studied is more abundant in surface horizons and decreases with depth. However, the contents of calcium, magnesium and potassium are lower in the surface horizons and increase with depth.

    Full Text Available A study designed to characterize the effects of shellfish products on the chemical properties of fluvisols gleyic and yield of rice was carried out in Toumbokro, Yamoussoukro’s region, Côte d'Ivoire. The work has been focused on soil amendment by three types of shells (Achatina spp Donax spp and Ostrea spp. Three doses of shellfish products (500, 1000 and 1500 kg.ha- 1 and NPK fertilizer were tested in a split-plot design with three repetitions. At ground level, the study showed that the shellfish products have positive effects very marked on all the physical and chemical characteristics. The effects of these shellfish products on the richness of the soil occur gradually. The increase of pH, due to the products made, creates a condition favorable to microorganisms that become active and mineralize sufficient organic substances. The study indicates that shellfish products induce high levels of production of rice cultivation. The average of yield of the experiments carried out is set at 5.41 t.ha-1 in Toumbokro. These performances, never recorded insubsistence agriculture, are explained by the effective correction of mineral deficiencies unsuspected soil by the flow of shellfish products. All the variables studied define the contribution of 1000 kg.ha-1 shredded shells of Achatina spp, as the optimum for soil amendment.

    An important epidemiologic feature of schistosomiasis is the focal distribution of the disease. Thus, the identification of high-risk communities is an essential first step for targeting interventions in an efficient and cost-effective manner. We used a remotely-sensed digital elevation model (DEM), derived hydrologic features (i.e., stream order, and catchment area), and fitted Bayesian geostatistical models to assess associations between environmental factors and infection with Schistosoma mansoni among more than 4,000 school children from the region of Man in western Côte d'Ivoire. At the unit of the school, we found significant correlations between the infection prevalence of S. mansoni and stream order of the nearest river, water catchment area, and altitude. In conclusion, the use of a freely available 90 m high-resolution DEM, geographic information system applications, and Bayesian spatial modeling facilitates risk prediction for S. mansoni, and is a powerful approach for risk profiling of other neglected tropical diseases that are pervasive in the developing world.

    The potential impact of irrigated agriculture on water-related vector-borne diseases has been an increasing source of concern for researchers from the bio-medical sector. While most research on the potential impacts of irrigation on the health of local populations focuses on vector densities, levels of exposures, health services and technologies (prophylaxis, mosquito nets), we argue that it is essential to enlarge the scope of investigation and consider the complex mechanisms by which factors such as agriculture-generated changes in ecosystems, gender repositioning in the family organization as a result of access to new crops, and production activities combine together in increasing disease risks and producing new scenarios in the management of disease. This paper presents the results of an investigation of how transformations induced on the local society by the intensification of inland valley irrigated rice cultivation influence malaria health care systems and modulate risks to the health of local populations, within well-defined geographical boundaries in northern Côte d'Ivoire. Our results indicate that socio-economic transformations and gender repositioning induced, or facilitated, by the intensification of inland valley irrigated rice cultivation lead to a reduction of the capacity of women to manage disease episodes, contributing therefore to increase malaria incidence among farming populations.

    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.

    Full Text Available Abstract Background Cervical cancer screening is not yet standard of care of women attending HIV care clinics in Africa and presents operational challenges that need to be addressed. Methods A cervical cancer screening program based on visual inspection methods was conducted in clinics providing antiretroviral treatment (ART in Abidjan, Côte d'Ivoire. An itinerant team of midwives was in charge of proposing cervical cancer screening to all HIV-positive women enrolled in ART clinics as well as to HIV-negative women who were attending the Abidjan national blood donor clinic. Positively screened women were systematically referred to a colposcopic examination. A phone-based tracking procedure was implemented to reach positively screened women who did not attend the medical consultation. The association between HIV status and cervical cancer screening outcomes was estimated using a multivariate logistic model. Results The frequency of positive visual inspection was 9.0% (95% CI 8.0-10.0 in the 2,998 HIV-positive women and 3.9% (95% CI 2.7-5.1 in the 1,047 HIV-negative ones (p -4. In multivariate analysis, HIV infection was associated with a higher risk of positive visual inspection [OR = 2.28 (95% CI 1.61-3.23] as well as more extensive lesions involving the endocervical canal [OR = 2.42 (95% CI 1.15-5.08]. The use of a phone-based tracking procedure enabled a significant reduction of women not attending medical consultation after initial positive screening from 36.5% to 19.8% (p -4. Conclusion The higher frequency of positive visual inspection among HIV-positive women supports the need to extend cervical cancer screening program to all HIV clinics in West Africa. Women loss to follow-up after being positively screened is a major concern in cervical screening programs but yet, partly amenable to a phone tracking procedure.

    Stavudine is no longer recommended for use in first-line antiretroviral therapy (ART), but it remains in high demand worldwide because it is affordable. We report the clinical presentation and incidence of severe hyperlactatemia (SL) in HIV-infected adults who initiated ART between April 2005 and May 2009 in Côte d'Ivoire, West Africa. In a prospective cohort study at the HIV care center affiliated with the National Centre for Blood Transfusion, we used standardized forms to record baseline and follow-up data. We measured serum lactate levels for all adults on ART who showed signs of hyperlactatemia. SL was defined as serum lactate >2.5 mmol/liter. Overall, 806 adults initiated ART. Among the 591 patients (73%) on stavudine-containing regimens, 394 were women (67%); the median pre-ART CD4 count was 150/mm3 and the median body mass index was 20.9 kg/m2. These patients were followed for a median of 28 months. We detected SL only among patients taking stavudine. The incidence of SL was 0.55/100 person-years (PY) (95% CI 0.47-0.63) overall and 0.85/100 PY among women (95% CI 0.75-0.95). Among the eight patients with SL, 100% lost >9% of body weight before diagnosis, 100% had serum lactate >4 mmol/liter (range 4.2-12.1), 50% had pre-ART BMI >25 kg/m2, and three patients died (38%), accounting for 6.4% of deaths among patients taking stavudine. As long as HIV clinicians continue to use stavudine in sub-Saharan Africa, they should watch out for acute unexplained weight loss in patients taking ART, particularly among women and patients with high pre-ART BMI.

    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.

    Full Text Available Abstract Background Tanganya virus (TGNV, the only shrew-associated hantavirus reported to date from sub-Saharan Africa, is harbored by the Therese's shrew (Crocidura theresae, and is phylogenetically distinct from Thottapalayam virus (TPMV in the Asian house shrew (Suncus murinus and Imjin virus (MJNV in the Ussuri white-toothed shrew (Crocidura lasiura. The existence of myriad soricid-borne hantaviruses in Eurasia and North America would predict the presence of additional hantaviruses in sub-Saharan Africa, where multiple shrew lineages have evolved and diversified. Methods Lung tissues, collected in RNAlater®, from 39 Buettikofer's shrews (Crocidura buettikoferi, 5 Jouvenet's shrews (Crocidura jouvenetae, 9 West African pygmy shrews (Crocidura obscurior and 21 African giant shrews (Crocidura olivieri captured in Côte d'Ivoire during 2009, were systematically examined for hantavirus RNA by RT-PCR. Results A genetically distinct hantavirus, designated Azagny virus (AZGV, was detected in the West African pygmy shrew. Phylogenetic analysis of the S, M and L segments, using maximum-likelihood and Bayesian methods, under the GTR+I+Γ model of evolution, showed that AZGV shared a common ancestry with TGNV and was more closely related to hantaviruses harbored by soricine shrews than to TPMV and MJNV. That is, AZGV in the West African pygmy shrew, like TGNV in the Therese's shrew, did not form a monophyletic group with TPMV and MJNV, which were deeply divergent and basal to other rodent- and soricomorph-borne hantaviruses. Ancestral distributions of each hantavirus lineage, reconstructed using Mesquite 2.74, suggested that the common ancestor of all hantaviruses was most likely of Eurasian, not African, origin. Conclusions Genome-wide analysis of many more hantaviruses from sub-Saharan Africa are required to better understand how the biogeographic origin and radiation of African shrews might have contributed to, or have resulted from, the evolution

    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. 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. 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, pphysical fitness, irrespective of their helminth infection status. Future studies on children's physical fitness in settings where helminthiasis and malaria co-exist should include pre- and post-intervention evaluations and the measurement of hemoglobin and hematocrit levels and nutritional parameters as potential co-factors to determine whether interventions further improve

    Two years after the introduction of free Artesunate-Amodiaquine (ASAQ) and Artemether-Lumefantrine (AL) for the treatment of uncomplicated malaria in public health facilities in Côte d'Ivoire, we carried out this study to compare their efficacy and tolerability in three surveillance sites. It was a multicentre open randomised clinical trial of 3-day ASAQ treatment against AL for the treatment of 2 parallel groups of patients aged 2 years and above. The endpoints were (1) Adequate Clinical and Parasitological Response (ACPR) at day 28 and (2) the clinical and biological tolerability. Of the 300 patients who were enrolled 289, with 143 (49.5%) and 146 (50.5%) in the ASAQ and AL groups, respectively, correctly followed the WHO 2003 protocol we used. The PCR-corrected ACPR was 99.3% for each group. More than 94% of patients no longer showed signs of fever, 48 hours after treatment. Approximately 78% of the people in the ASAQ group had a parasite clearance time of 48 hours or less compared to 81% in the AL group (p = 0.496). Both drugs were found to be well tolerated by the patients. This study demonstrates the effectiveness and tolerability of ASAQ and AL supporting their continuous use for the treatment of uncomplicated P. falciparum malaria infection in Côte d'Ivoire.

    Full Text Available Enzymatic activities play a key role in the biochemical functioning of soils. As a consequence, they have been proposed as indicators of soil quality. This study was conducted at the Oumé benchmark site (Central-West, Côte d'Ivoire, and aimed at measuring the enzymatic activities involved in the phosphorus (acid phosphatase and alkaline phosphatase, nitrogen (N-acetyl-β-D glucosaminidase and carbon (β-glucosidase and N-acetyl-β-D glucosaminidase cycles. Soil from four main agro-ecological units (a secondary forest, a 20 year-old cocoa plantation, a 2 year-old Chromolaena odorata-based fallow and a continuous maize crop, representative of land-use systems in the area, were sampled for the measurement of enzymatic activities and chemical characteristics. Results showed that the enzymatic activity values were the highest in the fallow soil, whereas the maize crop displayed the lowest levels of enzymatic activity in soil. Moreover, soil from C. odorata fallow displayed the highest values of C, N, exchangeable bases (Mg2+, K+ contents, and CEC, and the lowest C:N ratio, which are characteristics of good quality soil. A Principal Component Analysis revealed a marked relationship between C, N and enzymatic activity levels, showing that these enzymes are suitable for monitoring soil quality in semi-deciduous forest areas in Central-West Côte d'Ivoire.

Of the 300 patients who were enrolled 289, with 143 (49.5%) and 146 (50.5%) in the ASAQ and AL groups, respectively, correctly followed the WHO 2003 protocol we used. The PCR-corrected ACPR was 99.3% for each group. More than 94% of patients no longer showed signs of fever, 48 hours after treatment. Approximately 78% of the people in the ASAQ group had a parasite clearance time of 48 hours or less compared to 81% in the AL group (p = 0.496). Both drugs were found to be well tolerated by the patients. This study demonstrates the effectiveness and tolerability of ASAQ and AL supporting their continuous use for the treatment of uncomplicated P. falciparum malaria infection in Côte d'Ivoire.

    World fertility data were used for Cote d'Ivoire, Cameroon, Ghana, and Nigeria. Estimates of marital fertility and its proportional reduction owing to the proximate determinants were computed using Fertility Exposure Analysis (FEA). Eight exposure states were identified in an interval of 3 years before the survey. Proximate determinants were estimated from an equation for subsequent regression analysis, which also included socioeconomic variables, e.g., place of residence, religion, work pattern, and husband's education. Except for the 25-29 age group in Cameroon and Cote d'Ivoire and the 15-19 age group in Cote d'Ivoire, age specific marital fertility was higher for women who had between 4 and 6 years of formal education than for those who had 7 or more years of schooling. Marital age specific fertility was higher for women who had 4-6 years of education than for uneducated women, except from the 2 oldest age groups in Cote d'Ivoire and the oldest age groups in Ghana. On the other hand, lower fertility also existed in poorly educated women in Cameroon, in the 15-19 age group in Cote d'Ivoire and Ghana, and also in 20-24 and 30-34 age groups in Nigeria. Women with no education had lower fertility than those with 1-3 years and 4-6 years of education. Breastfeeding made the greatest contribution to the reduction of marital fertility for the educational categories except for the most educated women in Cote d'Ivoire. Contraception had a weak effect on fertility in Nigeria and Cameroon but a strong effect in Cote d'Ivoire and Ghana. Postpartum abstinence had a small effect since the 1970s except in Nigeria where it depressed marital fertility by over 10%. In these 4 countries differences existed in the patterns of educational differentials in fertility-reducing impacts of the proximate determinants. The impact of maternal education on marital fertility is not uniformly predictable in all African countries.

    Handheld light microscopy using compact optics and mobile phones may improve the quality of health care in resource-constrained settings by enabling access to prompt and accurate diagnosis. Laboratory technicians were trained to operate two handheld diagnostic devices (Newton Nm1 microscope and a clip-on version of the mobile phone-based CellScope). The accuracy of these devices was compared to conventional light microscopy for the diagnosis of Schistosoma haematobium, S. mansoni, and intestinal protozoa infection in a community-based survey in rural Côte d'Ivoire. One slide of 10 ml filtered urine and a single Kato-Katz thick smear from 226 individuals were subjected to the Newton Nm1 microscope and CellScope for detection of Schistosoma eggs and compared to conventional microscopy. Additionally, 121 sodium acetate-acetic acid-formalin (SAF)-fixed stool samples were examined by the Newton Nm1 microscope and compared to conventional microscopy for the diagnosis of intestinal protozoa. The prevalence of S. haematobium, S. mansoni, Giardia intestinalis, and Entamoeba histolytica/E. dispar, as determined by conventional microscopy, was 39.8%, 5.3%, 20.7%, and 4.9%, respectively. The Newton Nm1 microscope had diagnostic sensitivities for S. mansoni and S. haematobium infection of 91.7% (95% confidence interval (CI) 59.8-99.6%) and 81.1% (95% CI 71.2-88.3%), respectively, and specificities of 99.5% (95% CI 97.0-100%) and 97.1% (95% CI 92.2-99.1%), respectively. The CellScope demonstrated sensitivities for S. mansoni and S. haematobium of 50.0% (95% CI 25.4-74.6%) and 35.6% (95% CI 25.9-46.4%), respectively, and specificities of 99.5% (95% CI 97.0-100%) and 100% (95% CI 86.7-100%), respectively. For G. intestinalis and E. histolytica/E. dispar, the Newton Nm1 microscope had sensitivity of 84.0% (95% CI 63.1-94.7%) and 83.3% (95% CI 36.5-99.1%), respectively, and 100% specificity.

    Full Text Available Abstract Background The spread of pyrethroid resistance in Anopheles gambiae s.s. is a critical issue for malaria vector control based on the use of insecticide-treated nets. Carbamates and organophosphates insecticides are regarded as alternatives or supplements to pyrethroids used in nets treatment. It is, therefore, essential to investigate on the susceptibility of pyrethroid resistant populations of An. gambiae s.s. to these alternative products. Methods In September 2004, a cross sectional survey was conducted in six localities in Côte d'Ivoire: Toumbokro, Yamoussoukro, Toumodi in the Southern Guinea savannah, Tiassalé in semi-deciduous forest, then Nieky and Abidjan in evergreen forest area. An. gambiae populations from these localities were previously reported to be highly resistant to pyrethroids insecticides. Anopheline larvae were collected from the field and reared to adults. Resistance/susceptibility to carbamates (0.4% carbosulfan, 0.1% propoxur and organophosphates (0.4% chlorpyrifos-methyl, 1% fenitrothion was assessed using WHO bioassay test kits for adult mosquitoes. Then, PCR assays were run to determine the molecular forms (M and (S, as well as phenotypes for insensitive acetylcholinesterase (AChE1 due to G119S mutation. Results Bioassays showed carbamates (carbosulfan and propoxur resistance in all tested populations of An. gambiae s.s. In addition, two out of the six tested populations (Toumodi and Tiassalé were also resistant to organophosphates (mortality rates ranged from 29.5% to 93.3%. The M-form was predominant in tested samples (91.8%. M and S molecular forms were sympatric at two localities but no M/S hybrids were detected. The highest proportion of S-form (7.9% of An. gambiae identified was in sample from Toumbokro, in the southern Guinea savannah. The G119S mutation was found in both M and S molecular forms with frequency from 30.9 to 35.2%. Conclusion This study revealed a wide distribution of insensitive

    Intestinal helminthiasis affects the health and academic performance of children in developing countries. To highlight a few socio-economic factors that impact the presence and upholding of intestinal helminthiasis, a cohort study was performed from February to June 2001. This study took place in Agboville in Southern Côte d'Ivoire on 363 children, under the age of 15, regularly enrolled in school and selected by two-step clustered sampling. After the survey was completed, their stools were examined using 3 methods: direct exam, Kato's technique, and Graham's anal scotch-test. Infected students received an appropriate anti-helminthic treatment. After performing a test two weeks later, a new sample of 348 parasite-free children was made up and re-examined after three months, through the aforementioned techniques. In this sample, we assumed that students who were infested in the initial exam were "exposed", while those who were not infested in the first place were deemed to be "not exposed". The results showed that 135 students out of the 360 admitted for the first exam were infested; or a 37.5% of intestinal helminthiasis prevalence (IC95%=30.5-45). The prevalent parasite species were Necator americanus (15%), Trichuris trichiura (13.6%), Schistosoma mansoni (10%). Twenty-eight per cent of 135 infested students were infected by more than one parasite. After three months, the incidence rate of intestinal helminthiasis calculated out of the remaining 336 students was 7.7% (IC95%=4.4-13.1). The likelihood of re-infestation amounted to 3.4 (IC95%=1.5-7.3). The pattern of re-infestation rates according to socio-economic factors differed from that of infested prevalence. The prevalent parasites in re-infested patients were Trichuris trichiura (16.3%), Schistosoma mansoni (12.5%). All intestinal nematodes and Schistosoma mansoni were observed. The most frequent parasites species where those transmitted cutaneously. The high re-infestation rate suggests that intestinal

    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 of

    Introduction Transgender women are at high risk for the acquisition and transmission of HIV. However, there are limited empiric data characterizing HIV-related risks among transgender women in sub-Saharan Africa. The objective of these analyses is to determine what factors, including sexual behaviour stigma, condom use and engagement in sex work, contribute to risk for HIV infection among transgender women across three West African nations. Methods Data were collected via respondent-driven sampling from men who have sex with men (MSM) and transgender women during three- to five-month intervals from December 2012 to October 2015 across a total of six study sites in Togo, Burkina Faso and Côte d'Ivoire. During the study visit, participants completed a questionnaire and were tested for HIV. Chi-square tests were used to compare the prevalence of variables of interest between transgender women and MSM. A multilevel generalized structural equation model (GSEM) was used to account for clustering of observations within study sites in the multivariable analysis, as well as to estimate mediated associations between sexual behaviour stigma and HIV infection among transgender women. Results In total, 2456 participants meeting eligibility criteria were recruited, of which 453 individuals identified as being female/transgender. Transgender women were more likely than MSM to report selling sex to a male partner within the past 12 months (p<0.01), to be living with HIV (p<0.01) and to report greater levels of sexual behaviour stigma as compared with MSM (p<0.05). In the GSEM, sexual behaviour stigma from broader social groups was positively associated with condomless anal sex (adjusted odds ratio (AOR)=1.33, 95% confidence interval (CI)=1.09, 1.62) and with selling sex (AOR=1.23, 95% CI=1.02, 1.50). Stigma from family/friends was also associated with selling sex (AOR=1.42, 95% CI=1.13, 1.79), although no significant associations were identified with prevalent HIV infection

    Full Text Available Abstract Background This study aimed at identifying factors influencing the development of Human African Trypanosomosis (HAT, or sleeping sickness in the focus of Bonon, located in the mesophile forest of Côte d'Ivoire. A previous study mapping the main daytime activity sites of 96 patients revealed an important disparity between the area south of the town- where all the patients lived- and the area north of the town, apparently free of disease. In order to explain this disparity, we carried out a spatial analysis of the key components of the pathogenic system, i.e. the human host, the tsetse vector and the trypanosomes in their environment using a geographic information system (GIS. Results This approach at the scale of a HAT focus enabled us to identify spatial patterns which linked to the transmission and the dissemination of this disease. The history of human settlement (with the rural northern area exploited much earlier than the southern one appears to be a major factor which determines the land use pattern, which itself may account for differences found in vector densities (tsetse were found six times more abundant in the southern rural area than in the northern.

    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

    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.

Neonatal prophylaxis was provided in Ditrame-Plus only: 7-day ZDV and sdNVP 48–72 h after birth. A 6-week pediatric HIV-RNA diagnosis was provided on-line in the Ditrame-Plus while it was only oriented on clinical symptoms in Ditrame. Six-week HIV-infected children received a daily cotrimoxazole prophylaxis in Ditrame-Plus while no prophylaxis was provided in Ditrame. The determinants of severe events (death or hospitalization > 1 day were assessed in a Cox regression model. Results Between 1995 and 2003, 98 out of the 1121 live-births were diagnosed as HIV-infected in peri-partum: 45 from Ditrame-Plus and 53 from Ditrame. The 18-month Kaplan-Meier cumulative probability of presenting a severe event was 66% in Ditrame-Plus (95% confidence interval [95%CI]: 50%–81% and 77% in Ditrame (95%CI: 65%–89%, Log Rank test: p = 0.47. After adjustment on maternal WHO clinical stage, maternal death, 6-week pediatric viral load, birth-weight, and breastfeeding exposure, the 18-month risk of severe event was lower in Ditrame-Plus than in Ditrame (adjusted Hazard Ratio (aHR: 0.55, 95%CI: 0.3–1.1, although the difference was not statistically significant; p = 0.07.

    Full Text Available Este artigo utiliza o método descritivo para analisar as origens e o caráter aparentemente intratável, mas evitável, dos fatores ancilares que implicaram a derrocada da Costa do Marfim, que já foi uma ilha de estabilidade política, uma vitrine de prosperidade econômica e de sucesso em uma África Ocidental mergulhada em guerras civis. O artigo investiga as políticas dos Estados colonial e pós-colonial até a morte do presidente Félix Houphouët-Boigny, a era pós-Houphouët e suas crises política e socioeconômica, e a má administração do legado de Boigny, que levaram ao conflito interno. As conseqüências da disputa interna também são investigadas nos níveis nacional e sub-regional, assim como as resoluções dos conflitos por meio das ineficientes iniciativas de paz de Accra que, inexoravelmente, levariam às conversas de paz de Lina-Marcoussis. Os resultados das negociações, a participação de poderes não africanos e o futuro da democracia na Costa do Marfim também são investigados.This paper uses descriptive method to analyse the origin and the seemingly intractable but avoidable ancillary factors that plunged Côte d'Ivoire, which was once the island of political stability, the showcase of economic prosperity and success in West Africa in the fangs of civil war. The paper surveys the policies of the colonial and postcolonial state till the death of President Félix Houphouët-Boigny, the post-Houphouët era and its lot of political and socio-economic upheavals and the mismanagement of the legacies of Boigny that led to the internal conflict. The consequences of the civil strife are also surveyed at the national and sub-regional levels as well as the resolutions of the conflict through the botched Accra peace initiatives that inexorably led to the Lina-Marcoussis peace talks. The aftermath of the negotiations and the involvement of extra-African powers and the future of democracy in Côte d'Ivoire are also looked into.

    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

    Pyrethroid resistance in malaria vectors has spread across sub-Saharan Africa. Alternative tools and molecules are urgently needed for effective vector control. One of the most promising strategies to prevent or delay the development of resistance is to use at least two molecules having unrelated modes of action in combination in the same bed net. We evaluated in experimental huts in Côte d'Ivoire, a new polyethylene long-lasting insecticidal net (LN) product, Olyset® Duo, incorporating permethrin (PER) and pyriproxyfen (PPF), an insect growth regulator (IGR). PPF alone or in combination with permethrin had a significant impact on fertility (7-12% reduction relative to control) and no effect on fecundity of wild multi-resistant An. gambiae s.s. These results triggered crucial research questions on the behaviour of targeted mosquitoes around the LN. To maximize the sterilizing effect of PPF in the combination, there would be a need for a trade-off between the necessary contact time of the insect with PPF and the surface content of the pyrethroid insecticide that is bioavailable and induces excito-repellency. © A.A.

    In Côte d'Ivoire, multidrug-resistant tuberculosis (MDR-TB) is a serious public health problem with a prevalence estimated at 2.5% in 2006. Zinc and copper are essential Trace element needed to strengthen the immune system and also useful in the fight against tuberculosis. The Cu / Zn ratio is a good indicator of oxidative stress. The principal aim of this study was to evaluate the serum concentration of some trace element and determine the Cu / Zn ratio in patients with multidrug resistant pulmonary tuberculosis (MDR-TB) before and after second line treatment of TB. Blood samples were obtained from 100 MDR-TB patients after confirmation of their status through the microscopic and molecular diagnosis of resistance to Isoniazid and Rifampicin by GeneXpert. The concentration level of zinc and copper were determined using flame air / acetylene atomic absorption spectrometer (AAS) Type Varian Spectr AA-20 Victoria, Australlia. A significant decrease in zinc levels (P TB patients compared to controls TB free. During treatment a significant reduction in Cu / Zn ratio (P TB. Therefore the evaluation of the zinc and copper status could represent essential parameters in monitoring of TB second line treatment for better treatment management.

    Human infections with the helminth species Strongyloides stercoralis encompass a wide clinical spectrum, ranging from asymptomatic carriage to life-threatening disease. The diagnosis of S. stercoralis is cumbersome and the sensitivity of conventional stool microscopy is low. New molecular tools have been developed to increase sensitivity. We compared the diagnostic accuracy of real-time PCR with microscopy for the detection of S. stercoralis and hookworm in human stool samples, and investigated the inter-laboratory agreement of S. stercoralis-specific real-time PCR in two European laboratories. Stool specimens from 256 randomly selected individuals in rural Côte d'Ivoire were examined using three microscopic techniques (i.e. Kato-Katz, Koga agar plate (KAP) and Baermann (BM)). Additionally, ethanol-fixed stool aliquots were subjected to molecular diagnosis. The prevalence of S. stercoralis and hookworm infection was 21.9% and 52.0%, respectively, whilst co-infections were detected in 35 (13.7%) participants. The diagnostic agreement between real-time PCR and microscopy was excellent when both KAP and BM tested positive for S. stercoralis, but was considerably lower when only one microscopic technique was positive. The sensitivity of KAP, BM and real-time PCR for detection of S. stercoralis as compared to a combination of all diagnostic techniques was 21.4%, 37.5% and 76.8%, respectively. The inter-laboratory agreement of S. stercoralis-specific PCR was substantial (κ=0.63, preal-time PCR and stool microscopy shows high accuracy for S. stercoralis diagnosis. Besides high sensitivity, PCR may also enhance specificity by reducing microscopic misdiagnosis of morphologically similar helminth larvae (i.e. hookworm and S. stercoralis) in settings where both helminth species co-exist.

    With the interruption of larva treatments done by OCP as part of onchocerciasis control in West Africa, Simulium came back in abundance in forest regions and savannah fertile valleys. In addition to the severe discomfort, nuisance by Simulium is in certain cases incompatible with land use. Since ground treatment of larval breading sites using insecticides is not always possible or efficient, it is therefore a necessity to develop other methods among which individual protection against Simulium bites. The general objective of our study was to evaluate different vegetable oil compound repellent formulas against Simulium bites. Activities were carried out in savannah zone (Niakaramandougou) and in forest zone (Soubré) in Côte d'Ivoire. The methodology consisted in catching blackflies on volunteers whose legs were rubbed with a repellent. Gobi raw oil and coconut, palm nut and gobi formulas (lotions and creams) were tested. During each session, which lasted from 07:00 am to 12:00 and from 03:00 pm to 06:00 pm, one person did not apply any repellent and was used as the control person. The results of our experimentations show that for a given zone (savannah, forest), a repellent (coconut, palm nut, gobi) and a compound (shea butter, vaseline), there is no significant difference between protection rates obtained with lotions (maximum: 21 bites/person/day) and those obtained with creams (maximum: 30 bites/person/day). In other respects, the lotion of a given repellent seems to be efficient in savannah as in the forest, in protecting against Simulium bites. It is the same situation with creams. So, repellents can be an efficient solution against Simulium nuisance. However, experimentations should continue to confirm the high repellency of tested formulas, proceed to the identification of principles and evaluate the toxicity and irritant effect of repellents to be applied on the skin.

    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.

    2007-01-01

    Drought settled over West Africa's Ivory Coast region when wet season rains came late in 2007. Instead of beginning in February, the rainy season didn't start until March, and steady rains didn't start until late March, said the Famine Early Warning System Network. Though the rain had started to alleviate the drought, vegetation was still depressed in parts of Cote d'Ivoire (Ivory Coast) between March 22 and April 6, 2007, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite captured the data used to make this image. The image shows current vegetation conditions compared to average conditions recorded since 2000. Areas where plants are growing more slowly or more sparsely than average are brown, while areas where vegetation is denser than average are green. The brown tint that dominates the image indicates that plants through most of the country are more sparse than normal. Among the crops affected by the lack of rain was West Africa's cocoa crop. About 70 percent of the world's cocoa comes from West Africa, and Cote d'Ivoire is a top grower, said Reuters. Cocoa prices climbed as the crop fell short. Farmers called the drought the worst in living memory, Reuters said. The delay in rainfall also led to water shortages in parts of Cote d'Ivoire, according to the United Nations Office for the Coordination of Humanitarian Affairs.

    Full Text Available Abstract Background At Yaokoffikro field site near Bouaké, in central Côte d'Ivoire, a group of experimental huts built in 1996 served over many years for the evaluation of insecticides against highly resistant mosquitoes. Breeding sites of mosquitoes and selection pressure in the area were maintained by local farming practices until a war broke out in September 2002. Six years after the crisis, we conducted bioassays and biochemical analysis to update the resistance status of Anopheles gambiae s.s. populations and detect other potential mechanisms of resistance that might have evolved. Methods An. gambiae s.s. larvae from Yaokoffikro were collected in breeding sites and reared to adults. Resistance status of this population to insecticides was assessed using WHO bioassay test kits for adult mosquitoes with seven insecticides: two pyrethroids, a pseudo-pyrethroid, an organochloride, two carbamates and an organophosphate. Molecular and biochemical assays were carried out to identify the L1014F kdr and ace-1R alleles in individual mosquitoes and to detect potential increase in mixed function oxidases (MFO, non-specific esterases (NSE and glutathione S-transferases (GST activity. Results High pyrethroids, DDT and carbamate resistance was confirmed in An. gambiae s.s. populations from Yaokoffikro. Mortality rates were less than 70% with pyrethroids and etofenprox, 12% with DDT, and less than 22% with the carbamates. Tolerance to fenitrothion was observed, with 95% mortality after 24 h. PCR analysis of samples from the site showed high allelic frequency of the L1014F kdr (0.94 and the ace-1R (0.50 as before the crisis. In addition, increased activity of NSE, GST and to a lesser extent MFO was found relative to the reference strain Kisumu. This was the first report detecting enhanced activity of these enzymes in An. gambiae s.s from Yaokoffikro, which could have serious implications in detoxification of insecticides.

    Full Text Available Effect of the number of recycled biomass of the yeast Saccharomyces uvarum on some parameters of primary fermentation during beer production in Côte d'Ivoire. A study was conducted on the yeast Saccharomyces uvarum during the production of beer to determine the impact of the number of recycled yeast biomass on some primary fermentation parameters and to understand variations during primary fermentation time. The work was carried out with six cycles of beer production. The first cycle was done with the initial culture of S. uvarum and the five others with its recycled biomass. After each cycle of production, the yeast biomass obtained is re-used to inoculate another mash and the same operation was repeated until the sixth cycle of production of the beer. Thus during each of the six cycles, several parameters such as the rate of fermentation, the diacetyle reduction time, the rate of alcohol production, etc. were measured. The fifth and sixth cycles showed the longest primary fermentation time (10 days and the longest diacetyle reduction time (6.8 and 7.6 days respectively. The first and second cycles have the shortest primary fermentation time (8.33 and 8.25 days respectively and diacetyle reduction time (3.33 days for each cycle. The interval between the theoretical and the practical attenuation limit differs according to the cycle of production. The highest gap (0.51 was obtained with the last cycle (sixth while the shortest was obtained with the first cycle, 0.13. The fermentation rate varied from 1.71 to 1.97°P per day. The quantity of sugar consumed varied from 8.83 to 10.70°P and the rate of alcohol produced from 4.56 to 4.90°P. The yeast from the two last cycles flocculated quicker than the others. The number of cells in suspension for these cycles was 4.1.106 and 4.2.106 cells.ml-1 respectively versus 25.106 and 20.106 cells.ml-1 respectively for the two first cycles. The yeast biomass from the first four cycles should be used for the

    Diseases caused by environmental contamination by micro-organisms, including intestinal helminths and protozoa, are prevalent in developing countries. According to some authors, their strong expansion in some zones of these countries is due primarily to favourable climatic conditions, combined with inadequate hygiene measures and cleaning and the generally low socio-economic level. Progress in disease control has resulted from new studies that improve our understanding of the epidemiology of helminthiases and from the availability of simple tools that are inexpensive and effective against these diseases (chemotherapy with albendazole and mebendazole). On the other hand, surprisingly few such studies have looked at intestinal protozoa, although the WHO reports that approximately 480 million individuals throughout the world are infested by amoebiasis caused by the protozoon Entamoeba histolytica and that 40,000-110,000 people die from it each year. Giardiasis, a cosmopolitan parasitosis, is due to another intestinal protozoon called Giardia intestinalis. To help develop a database on these parasites, we conducted a cross-sectional epidemiological survey in the Man region in western Côte d'Ivoire. Its objectives were to determine the prevalence of intestinal protozoa, to evaluate polyparasitism and to assess the spatial distribution of the pathogenic protozoal species, E. histolytica and G. intestinalis. Overall, 4466 stools samples taken from pupils aged 6 to 16 years of age at 57 different schools were analyzed under an optical microscope by the formol-ether stool concentration method, after preservation in sodium acetate-acetic acid-formalin (SAF). The most common protozoa species in this area were Endolimax nanus (83.8%) and E. coli (74.7%). The regional prevalence of G. intestinalis was 17.5% and of E. histolytica/E. dispar 11.3%. Both species were found in each of the 57 schools. The prevalence of E. histolytica/E. dispar exceeded 15% in six schools, and its

    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.

    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.

    1998-01-01

    This article reviews scientific and other literature during the 1990s that links migration and mobility with the spread of sexually transmitted diseases (STDs), including HIV/AIDS. The focus is on key population groups linked to the spread of HIV and STDs in West and Central Africa: migrant laborers, truck drivers, itinerant traders, commercial sex workers (CSWs), and refugees. Countries with high emigration and immigration tend to have high levels of HIV infection, with the exception of Senegal. The main destination of immigrants are Senegal, Nigeria, and Cote d'Ivoire in West Africa and Cameroon, Congo, Gabon, and Congo in Central Africa. The risk of infection and the spread of HIV is variable among migrants. There is little in the literature that substantiates hypotheses about the strong association between migration and HIV-positive status. Information is needed on the duration, frequency of return visits, living conditions, sexual activities with multiple partners, and information before departure, along the routes, at final destination, and at the time of returns. Action-based research in five West African countries (Burkina Faso, Cote d'Ivoire, Mali, Niger, and Senegal) should produce results in late 1998. Comparable studies in Central Africa are unknown. Regional studies should be complemented by local studies. Prevention would benefit from studies on the relative size of these five population groups by geographic location.

    Background While antiretroviral treatment (ART)-related adverse drug reactions (ADR) are documented in industrialized countries, there is no pre-existing surveillance system dedicated to ADR monitoring in most African countries. We assessed knowledge towards pharmacovigilance among ART prescribers and available capacity of HIV clinics to conduct ADR monitoring in Abidjan, Côte d’Ivoire. Methods A questionnaire was administered to ART prescribers, to assess their knowledge towards the occurrence of ADRs. A retrospective ADR survey was also conducted, based on a data query of treatment modification/interruptions in three HIV clinics. Clinical monitors went back to medical charts to review and validate the reasons of the treatment modification/interruptions. Results Of the 81 ART prescribers interviewed, 25 (31%) declared not grading ADRs and 12 (14.8%) declared notifying ADRs to the national regulatory authorities. Among 5,252 adult ART-treated patients who attended the participating clinics in 2008, 599 treatment modifications were identified. Reasons for treatment modification/interruptions identified in the electronic database were documented in the medical charts in 554 (92.5%) cases, ADR accounting for 273 (45.5%) cases. Toxicity related to ART was graded in only 58 (21%) cases in the medical charts. Discussion This study describes challenges limiting the implementation of reliable pharmacovigilance activities in HIV clinics in Côte d’Ivoire. The lack of knowledge of ART prescribers concerning ADR grading does not support the spontaneous reporting of ADRs. Using treatment modification/interruptions for ADR monitoring appears feasible but improvements are needed to respond to key questions related to drug toxicities in the context of ART scale up in Africa.

    Serological studies indicate that rates of ocular toxoplasmosis (OT) vary geographically, with higher rates in tropical regions. Little is known about population-based rates of active OT. We aimed to describe the epidemiology of OT in Central Cuba. This large-population, cross-sectional cohort study used a prospective database at a large regional referral centre in Central Cuba. The patient database was searched for all patients who presented with OT during the 12-month study period from 1 April 2011 to 31 March 2012. Inclusion criteria were the clinical diagnosis of OT, characterised by focal retinochoroidal inflammation and a response to therapy as expected. Gender-stratified and age-stratified study population data from the 2012 Cuban Census were used to calculate incidence rates and prevalence ratios. Among 279 identified patients with OT, 158 presented with active OT. Of these, 122 new-onset and 36 prior-onset cases were confirmed. Based on the total population in the Sancti Spiritus province (466,106 persons), the overall incidence of active OT was 26.2 per 100,000 person-years (95% CI 21.7 to 31.3) with an annual prevalence ratio of 33.9 per 100,000 persons (95% CI 28.8 to 39.6). The incidence of active OT was lowest in the oldest age group and highest in patients aged 25-44 years (4.5 and 42.1 per 100,000 person-years, respectively). This first report describing population-based rates of OT in the Cuban population highlights the importance of patient age as a likely risk factor for OT. Disease rates were found to be highest in females and young to middle-aged adults. Published by the BMJ Publishing Group Limited.

    Full Text Available Kidney transplantation from living kidney donors (LKDs because of its good results represents a good option for the treatment of patients with the end-stage renal disease. Kidney donation is a relatively safe procedure according to several studies. We conducted this cross-sectional study in order to describe the demographic, clinical, and renal outcome of LKD in Cτte d′Ivoire. From March to November 2014, LKD residing in Cτte d′Ivoire at the time of investigation and having donated the kidney more than one year ago were considered for the study. They were evaluated through a questionnaire. Of the 29 LKD listed in Cτte d′Ivoire, only 14 responded to the questionnaire. The mean age at donation was 43.29 ± 9.12 years (27-59 and 10 of the LKD were women. Eight were related to the recipients, and the remaining were spouses. Laparoscopic nephrectomy was performed in nine LKD. The left kidney was harvested in ten cases. The main motivation for donation in all donors was the desire to save a life. At the time of the survey, the average duration after the donation was 4.57 ± 2.56 years (1-8. Only five donors had a regular nephrological follow-up. Hypertension was observed in one donor, seven had significant proteinuria, and six had glomerular filtration rate 30 mL/min. Significantly higher proteinuria was noted in donors under 45 years as compared to those over 45 years (0.43 ± 0.17 g/24 h vs. 0.22 ± 0.03 g/24 h, P = 0.01. Our study suggests that renal disease in LKD in Cτte d′Ivoire is low after a mean follow-up period of four years. A donor registry is essential to ensure better follow-up of donors in order to detect potential adverse effects of kidney donation in the medium as well as in the long-term.

    This paper is purely expositional. The statement of the Gauss criterion for constructibility of regular polygons is simple and well-known. We sketch an elementary proof of this criterion. We do not use the terms 'field extension', 'Galois group' and even 'group'. However, our presentation is a good way to learn (or recall) starting idea of the Galois theory. The paper is accessible for students familiar with elementary algebra (including complex numbers), and could be an interesting easy reading for mature mathematicians. The material is presented as a sequence of problems, which is peculiar not only to Zen monasteries but also to elite mathematical education (at least in Russia); most problems are presented with hints or solutions. An English version is followed by a more extended Russian version.

    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.

    In this study we analyze the travel patterns of 500,000 individuals in Cote d'Ivoire using mobile phone call data records. By measuring the uncertainties of movements using entropy, considering both the frequencies and temporal correlations of individual trajectories, we find that the theoretical maximum predictability is as high as 88%. To verify whether such a theoretical limit can be approached, we implement a series of Markov chain (MC) based models to predict the actual locations visited by each user. Results show that MC models can produce a prediction accuracy of 87% for stationary trajectories and 95% for non-stationary trajectories. Our findings indicate that human mobility is highly dependent on historical behaviors, and that the maximum predictability is not only a fundamental theoretical limit for potential predictive power, but also an approachable target for actual prediction accuracy.

    The economy of Côte d'Ivoire rests on the agriculture. In order to contribute to the development of this agriculture, we have oriented our research field on applied optics to agriculture. Then, our research concerns mainly the Laser Induced chlorophyll fluorescence in plants. A simple laser-induced fluorescence set up has been designed and built at the Laboratory of Crystallography and Molecular Physics (LaCPM) at the University of Cocody (Abidjan, COTE D'IVOIRE). With this home set up we first have studied the fluorescence spectra of the "chlorophyll" to characterize the potassium deficiency in oil palm (Elaeis guineensis Jacq,). However, we found that the results differed for samples along terraced plots. The study of this phenomenon called "border effect", has enabled us to realize that sampling should be done after two rows of safety in each plot. We also applied the Laser Induced chlorophyll fluorescence technique to improve the plant breeding. For this, we have characterized the rubber tree seedlings in nurseries. And so we have highlighted those sensible to drought and resistant ones.

    The objective of this study was to document the influence of pornography on the sexual behaviour of school children in the Cocody district of Abidjan, Cote d'Ivoire. This cross-sectional, descriptive and analytical study was conducted from October to November 2013 with pupils from four schools in Cocody, Abidjan. A total of 398 pupils (224 boys and 174 girls) were interviewed: 14.3% of them had access to pornography on internet or television. 52.8% (210) of the 398 pupils interviewed were sexually active at the time of the survey, 41.9% (88/210) of whom had at least two sexual partners. On bivariate analysis,access to pornography was statistically associated with being sexually active (OR= 2.61; 95%CI [1.41; 4.83]), early onset of sexual intercourse (OR= 2.38; 95%CI = [1.19; 4.76]) and multiples exual partners (OR== 6.09; 95%CI= [2.79; 13.3])Conclusion: The results of this study demonstrate that access to pornography had a negative influence on the sexual behaviour of school children in Abidjan (Côte d'Ivoire].

    The IPCC has recently documented substantial changes in the global heat content of the oceans, salinity, sea level, thermal expansion and biogeochemistry. Over the 21. century anticipated climate related changes include: a rise in sea level of up to 0.6 m or more; increases in sea surface temperatures up to 3 deg. C; an intensification of tropical and extra tropical cyclones; larger extreme waves and storm surges; altered precipitation/ run-off; and ocean acidification. The Tyndall Centre has been exploring how to down-scale the global analysis to the local level within the framework of a coastal simulator. The simulator provides information on possible future states of the coast through the 21. Century under a range of climate and socio-economic futures and shoreline management options. It links models within a nested framework, recognizing three scales: (1) global, (2) regional, and (3) local. The linked models describe a range of processes, including marine climate (waves, surges and mean sea level), sand bank morpho-dynamics, wave transformation, shoreline morpho-dynamics, built environment scenarios, ecosystem change, and erosion and flood risk. Analyses from the simulator reinforce conclusions from IPCC WG2: coasts will be exposed to increasing risks over coming decades due to many compounding climate-change factors; the impact of climate change on coasts will be exacerbated by increasing human induced pressures; the unavoidability of sea-level rise even in the longer-term frequently conflicts with present day human development patterns and trends.

    Ochratoxin A (OTA) is a mycotoxin produced mostly by several species of Aspergillus and Penicillium. OTA is nephrotoxic in all animal species in which it has been tested and is cancerogenic in rodents. It is associated with Balkan endemic nephropathy. It is naturally present in many crop products such as cereals (barley, wheat, maize) and dried fruits, spices, coffee, wine, olives, and cocoa. The aim of this study was to assess the contamination of three Ivoirian spices with OTA (ginger, chili, and pepper) widely consumed by the population. A total of 90 spice samples (ginger: n = 30; chili: n = 30; pepper n = 30) was taken from various sales outlets of Abidjan. OTA was quantified using an HPLC apparatus coupled with a fluorimetric detector. The chili and ginger samples were contaminated with OTA at a mean concentration of 57.48 ± 174 and 0.12 ± 0.15 μg/kg, respectively. No contamination of the pepper samples was detected. Eight (26.67 %) of the chili samples exceeded the maximum limit of 15 μg/kg established by European regulation. These results should serve as an alert on the risk to the consumer population of these products that are highly contaminated with OTA.

    Pediatric human immunodeficiency virus (HIV) infection remains an important public health issue in resource-limited settings. In 2015, 1.4 million children aged HIV (including 170,000 infants born in 2015), with the vast majority living in sub-Saharan Africa (1). In 2014, 150,000 children died from HIV-related causes worldwide (2). Access to timely HIV diagnosis and treatment for HIV-infected infants reduces HIV-associated mortality, which is approximately 50% by age 2 years without treatment (3). Since 2011, the annual number of HIV-infected children has declined by 50%. Despite this gain, in 2014, only 42% of HIV-exposed infants received a diagnostic test for HIV (2), and in 2015, only 51% of children living with HIV received antiretroviral therapy (1). Access to services for early infant diagnosis of HIV (which includes access to testing for HIV-exposed infants and clinical diagnosis of HIV-infected infants) is critical for reducing HIV-associated mortality in children aged HIV testing services for early infant diagnosis was assessed. During 2011-2015, the total number of HIV diagnostic tests performed among HIV-exposed infants within 6 weeks after birth (tests for early infant diagnosis of HIV), as recommended by the World Health Organization (WHO) increased in all seven countries (Cote d'Ivoire, the Democratic Republic of the Congo, Haiti, Malawi, South Africa, Uganda, and Zambia); however, in 2015, the rate of testing for early infant diagnosis among HIV-exposed infants was HIV positivity among those tested declined in all seven countries, with three countries (Cote d'Ivoire, the Democratic Republic of the Congo, and Uganda) reporting >50% decline. The most common challenges for access to testing for early infant diagnosis included difficulties in specimen transport, long turnaround time between specimen collection and receipt of results, and limitations in supply chain management. Further reductions in HIV mortality in children can be achieved through

    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.

  4. WHO still reeling from racism charges.

    1995-06-01

    The World Health Organization (WHO) is not as prestigious as it used to be. It operates on a relatively small annual budget of $1.8 billion, the WHO 1995 audit suggested irregularities in the way contracts were awarded and criticized a lack of control over funds at the WHO's African headquarters in the Congo, and its director, Hiroshi Nakajima, has been accused of being a racist against Africans. Nakajima complained during a January 1995 WHO board meeting that some African members had poor English skills. Delegates from several African nations to the annual World Health Assembly, which began in Geneva on May 1, subsequently raised the issue and called for the Japanese director to resign. The release of the recent WHO health report, "Bridging the Gaps," was an attempt by the organization to regain some its international respect, but little new was reported. Basic messages were that poverty is the most important cause of ill health, 60% of all new HIV infections occur among people aged 15-24 in many countries, 50% of people with HIV globally are younger than 25 years old, 60% of infections in women occur by age 20, and life expectancy is increasing in all countries except Cote d'Ivoire, Central African Republic, Congo, Uganda, and Zambia, all countries hard-hit by HIV/AIDS. For now, Nakajima has retained his position, although British and US donors stress that they will keep closer watch over the organization and that reforms must be made.

    This article discusses return migration and evaluates the government's role in developing the potential of return migrants in Senegal. The three sections give a profile of return migrants, Senegal's pertinent official policies, and recommendations for action to improve reintegration into the local context. Although capital and goods flow freely in the global marketplace, globally, the flows of workers are constrained by restrictive immigration policies of host countries. Senegal and France have agreed to cooperate by containing migration flows and promoting migrants as agents of development, who can bring needed skills back to the countries of origin. Senegal has out-migration of about 50% of the poorest households. Receiving countries are scattered throughout the world. France receives about 105,000 and Cote d'Ivoire receives about 150,000. Migrants may be registered or unregistered. Migrants maintain close ties in their homeland and send remittances. Since 1980, France has provided specific training in Senegal and France for migrants willing voluntarily to return to Senegal. The aim is to involve migrants in national development. The Organization for Scientific and Technical Research is studying the impact of "brain drain" and seeks to enable native countries to reap rewards from their nationals without seeking repatriation.

    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.

    Phylogeography of Rice yellow mottle virus (RYMV) was reconstructed from the coat protein gene sequences of a selection of 173 isolates from the 14 countries of mainland Africa where the disease occurred and from the full sequences of 16 representative isolates. Genetic variation was linked to geographical distribution and not to host species as isolates from wild rice always clustered with isolates from cultivated rice of the same region. Genetic variation was not associated to agro-ecology, viral interference and insect vector species. Distinct RYMV lineages occurred in East, Central and West Africa, although the Central African lineage included isolates from Benin, Togo and Niger at the west, adjacent to countries of the West African lineage. Genetic subdivision at finer geographical scales was apparent within lineages of Central and West Africa, although less pronounced than in East Africa. Physical obstacles, but also habitat fragmentation, as exemplified by the small low-lying island of Pemba offshore Tanzania mainland, explained strain localization. Three new highly divergent strains were found in eastern Tanzania. By contrast, intensive surveys in Cote d'Ivoire and Guinea at the west of Africa did not reveal any new variant. Altogether, this supported the view that the Eastern Arc Mountains biodiversity hotspot was the centre of origin of RYMV and that the virus spread subsequently from east to west across Africa. In West Africa, specific strains occurred in the Inner Niger Delta and suggested it was a secondary centre of diversification. Processes for diversification and dispersion of RYMV are proposed.

  8. Feasibility of local condom production examined.

    Science.gov (United States)

    1999-01-01

    Despite Africa being the world region worst affected by the HIV/AIDS pandemic, there is only 1 condom manufacturer on the continent, in Johannesburg. Hundreds of millions of condoms are donated and imported annually. For example, 500 million units were donated in 1996, of which 212 million came from the US Agency for International Development. A recently released study commissioned by the European Union's HIV/AIDS Program for Developing Countries determined that it would be technically viable to manufacture condoms in not only South Africa, but also in Mauritius, Cote d'Ivoire, and Kenya. All that is required is a factory, work force, water, and electricity, with the raw materials to be imported from Malaysia or Thailand regardless of where the factory is located. The financial returns of such an operation would depend upon the cost of labor, the type of factory and its output, and market demand. Benefits would include employment creation, potential exports, and foreign exchange savings. A typical condom plant, operating 24 hours a day with 2 production lines, can produce 160 million condom units per year. However, should such a factory be built and put into operation, managers must ensure that any condoms produced are of high quality.

    Ochratoxin A (OTA) is a mycotoxin mainly produced by mould species of the genera Aspergillus and Penicillium, which grow on a variety of agricultural products. OTA-contaminated foodstuffs pose a major health hazard to consumers, including human and animal. In Cote d'Ivoire, numerous studies are being carried out to find the best way of preventing OTA contamination of cocoa raw material. The objectives of this investigation were to assess the impact of industrial treatment on OTA content in cocoa-derived products. Samples of cocoa pods were prepared under specific conditions promoting fungal proliferation on cocoa beans before processing. The beans underwent the usual industrial treatments - roasting, shelling, crushing, pressing and additive addition - and samples were taken at each stage. OTA was extracted with a methanol/3% sodium hydrogen carbonate solution and purified using an immunoaffinity column prior to HPLC analysis with fluorescence detection. OTA was detected in artificially contaminated cocoa beans at levels ranging from 3.4 to 44.7 microg kg(-1) with a mean value of 22.9 +/- 3.6 microg kg(-1). OTA was mainly concentrated in the shell (93%). Roasting, shelling and additive addition significantly decreased levels of OTA by 24-40, 76 and 52%, respectively, with an overall reduction of approximately 91%. These results indicate that industrial processing of cocoa has a real impact on the reduction of OTA in final cocoa products.

  10. 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.

    Ochratoxin A (OTA) is a mycotoxin produced mainly by species of Aspergillus and Penicillium. Contamination of food with OTA is a major consumer health hazard. In Cote D'Ivoire, preventing OTA contamination has been the subject of extensive study. The current study was conducted to evaluate the influence of fermentation and drying materials on the OTA content in cocoa. For each test, 7000 intact cocoa pods were collected, split open to remove the beans, fermented using 1 of 3 different materials, sun-dried on 1 of 3 different platform types and stored for 30 days. A total of 22 samples were collected at each stage of post-harvesting operations. The OTA content in the extracted samples was then quantified by high-performance liquid chromatography. OTA was detected in beans at all stages of post-harvesting operations at varying levels: pod-opening (0.025 ± 0.02 mg/kg), fermentation (0.275 ± 0.2 mg/kg), drying (0.569 ± 0.015 mg/kg), and storage (0.558 ± 0.04 mg/kg). No significant relationships between the detected OTA level and the materials used in the fermentation and drying of cocoa were observed.

    Antibodies against peste des petits ruminants virus (PPRV) were first detected in goats in East Africa in 1995 without any clinical disease. It was not until during the years 2006 and 2007 that the disease outbreaks were first reported in Kenya and Uganda, respectively. This study was carried out to detect and characterize PPRV from a suspected outbreak in sheep and goats in the Karamoja region in 2007-2008. Oculo-nasal and blood samples were tested using F-gene-based primers, and their genetic relationships to other sequences in the GenBank database were investigated. A total of 383 samples suspected to contain PPRV were randomly collected and tested. Sixty-seven (17.5%) were positive when F protein gene primers were used. During the years 2007 and 2008, 38.1% (26/67) and 13.0% (41/316) of samples were positive by PCR, respectively. The 2007 sequences clustered with Asian sequences in lineage 4 and Cote d'Ivoire 86 (ICV 86) in lineage 2, while all of the 2008 samples clustered in lineage 1. Over the years, the implicated strains were genetically close (88%-91%) to the vaccine strain (Nig 75/1). Based on this study, the circulating PPR strains in Uganda are heterogeneous, and therefore, the disease may have been introduced from different sources.

    Changes in diet throughout hominin evolution have been linked with important evolutionary changes. Stable carbon isotope analysis of inorganic apatite carbonate is the main isotopic method used to reconstruct fossil hominin diets; to test its effectiveness as a paleodietary indicator we present bone and enamel carbonate carbon isotope data from a well-studied population of modern wild western chimpanzees (Pan troglodytes verus) of known sex and age from Taï, Cote d'Ivoire. We found a significant effect of age class on bone carbonate values, with adult chimpanzees being more (13)C- and (18)O-depleted compared to juveniles. Further, to investigate habitat effects, we compared our data to existing apatite data on eastern chimpanzees (P. troglodytes schweinfurthii) and found that the Taï chimpanzees are significantly more depleted in enamel δ(13)Cap and δ(18)Oap compared to their eastern counterparts. Our data are the first to present a range of tissue-specific isotope data from the same group of wild western chimpanzees and, as such, add new data to the growing number of modern non-human primate comparative isotope datasets providing valuable information for the interpretation of diet throughout hominin evolution. By comparing our data to published isotope data on fossil hominins we found that our modern chimpanzee bone and enamel data support hypotheses that the trend towards increased consumption of C4 foods after 4 Ma (millions of years ago) is unique to hominins.

  14. Cost recovery shifts the brand image from Prudence to Protector.

    Social marketing programs are underway in Africa. One program markets condoms in Zaire and Cote d'Ivoire under the brand name Prudence. While a cost element does exist, this program was largely designed to demonstrate the viability of social marketing programs. Emphasis has now been placed upon recovering costs, and condoms are marketed under the name of Protector. Since the US wants to reduce its role as the dominant funder of condom distribution in Africa, and governments and other donors want to be able to buy condoms more cheaply on the open market, the recent cost recovery version of the program will most likely displace the initial version. The Protector program strives toward achieving scale economies and financial self-sufficiency. Specifically, the program aims to standardize campaign materials across all participating countries, make private sector partner organizations in each country responsible for local distribution and marketing, and have earnings pay for a predefined part of program expenditures. Conceptually, Prudence is marketed to prevent AIDS, while Protector is promoted more broadly against sexually transmitted diseases and unwanted pregnancies. Social marketing programs are spreading and condom use is on the rise. The World Health Organization Global Program on AIDS sees its role as advocating condom use and encouraging donors to fund social marketing programs.

La tendencia en tiempos recientes es a una reducción de la clorofila a y un aumento en la trasparencia del agua. Estos cambios son similares a los observados en lagos donde se ha logrado atribuirlos al cambio climático global. También se pueden deber a la modificación del flujo del efluente por la operación intermitente de la planta hidroeléctrica, que favorece la acumulación de calor en la columna de agua. Esto debido a que otros factores, como el cambio en el uso del suelo en los alrededores del lago ocurrieron en la década de 1980, por lo que no se les puede atribuir una influencia en los cambios observados en los últimos 10 años.

    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 liberalization of the cotton sector in Ivory Coast is inspired by industrialized countries. Its approaches are supported by the Breton Woods institutions and the French Cooperation. The aim of this study is to review spatial and organizational reforms in the cotton basin of Ivory Coast. The results of this research revealed that liberalization is the cause of the restructuring of the cotton area. On the other hand, it has resulted an organizational dynamic based on the activity of the cotton companies and producers. In addition, the areas defined by the liberalization are not respected by cotton agencies. This non-compliance is manifested by the incursion of cotton companies in areas outside their initial block. In this logic of incursion, the producers of public society (CIDT produce significantly more than those supervised by private cotton companies. This observation raises a debate regarding the continued liberalization of the cotton sector in Ivory Coast.

    Rheumatoid factor (RF) is a major source of interference in immunoassays. Several methods have been proposed to eliminate interference. We experimented with a new technique based on the depletion of rheumatoid factor from serum samples. Our study included 150 samples, 64 of them positive for RF. Depletion was performed by the adsorption of RF from the sample by latex beads sensitized with human IgG anti-RF. After precipitation of the complexes formed, the supernatant was tested for RF. Finally, we assessed the performance of this RF depletion method with two tests: ELISA Enzygnost Enzygnost anti-HBs micro-Behring and IFI falciparum Ref 75521 Biomerieux. We compared the percentages of false-negative and false-positive results of these tests before and after depletion of the RF-positive serum samples. Efficiency index is 92.2% and the performance of the two immunoassay tests improved significantly by a factor of 2 to 25 after depletion. In addition, this technique is easy, inexpensive, fast, and suitable to our limited resources as a developing country. It should be extended to other immunological tests for validation of the results.

    Full Text Available Assessment of the Economic Impact of Glandless Cotton in Ivory Coast. This study presents the results of an ex-post assessment of the economic impact of glandless cotton introduced in farming system in north Ivory Coast. The researches on this type of cotton plant have been conducted since 1975 until now in Bouaké. From 1980 to 1995, the extension office has released new glandless cotton varieties. They were intended mainly to obtain a more competitive fiber on the world market as well as edible grain for animals (cakes and for man (oil, flour. A surplus economic estimated model has been applied for this analysis. Upon the basis of the hypothesis retained in this analysis, the net present value estimated is negative. These results put in evidence the economic failure of the glandless cotton research and extension program in Ivory Coast. Furthermore, the lower productivity at farm level induced a decrease of total fiber and oil productions. This study presents three interests. Firstly by showing that it is possible to have a good idea about an ex-post assessment of public investment in agriculture. Secondly by showing clearly that an extension program success depends on its capability to solve farmer's real problems. Thirdly, it gives a good feed-back to agricultural researchers.

    Full Text Available It is generally assumed that African states have yet to explore the full potential of their traditional institutions and the specific role that society wants them to play in modern states. While focusing on Nigeria and Côte d’Ivoire, this empirical research seeks to explore legal pluralism in modern African democracy. The study specifically answers the research question: is the traditional justice system applicable to Nigerians and Ivorians in contemporary dispensation? The study finds out that a significant population at the grassroots rely on the traditional justice system, when compared with their counterparts in the cities. The rural population argues that the formal justice system is quite expensive and that the legal procedures are difficult to understand, coupled with the fact that court houses are mostly located in the cities. On the other hand, the gender-biased and male-dominated outlook of the traditional justice mechanism and its proneness to external influences, as well as the impact of modern religions, have continued to propel a considerable population (especially in urban areas to patronize the formal justice system. Meanwhile, the adoption of western institutions of government by African states has forced traditional institutions to occupy the back seat. Hence, there is a mixed social environment wherein both formal and traditional justice systems are weak, and the states being weak themselves are significantly responsible for the weakness of traditional institutions. Consequently, flaws in both justice systems have compelled people to take the law into their own hands and to resort to jungle justice.

    The general aim of this study is to update the inventory of the fish species and to specify distribution patterns in the Nero River ichthyofauna in order to establish some basis for the conservation of these fish communities and their habitat. From February 2009 to January 2010, thirty-three sites were sampled monthly with gill nets and a backpack electrofisher, and environmental variables were recorded. Overall, 46 species included in 33 genuses, 24 families and 9 orders were collected. Eleven families and 30 species were the first records for the Nero River. Including all species previously listed in the literature, the number of species presently known in the Nero River and its tributaries is revised to 59. Four families, Alestidae (21%), Schilbeidae (19%), Cyprinidae (17%) and Cichlidae (16%) that made up 73% of the total number of the catches, were the most dominant. The most dominant numerical species were Schilbe mandibularis and Brycinus longipinnis. Fish species and sampling sites along with eight environmental variables were ordinated with canonical correspondence analysis (CCA) coupled to the Monte Carlo test. Ecological status based on fish assemblage according to environmental variables and anthropogenic pressures showed that miss dead wood leaves and roots, electrical conductivity, total dissolved solids, mud, nitrite, basin width, dissolved oxygen and pH, were the primary factors influencing fish distribution. The environmental tolerance index (ETI), ecological tolerance (tk ) and optima (uk ) values of 10 species to 8 different environmental variables were analyzed. Six species (Hemichromis fasciatus, Epiplatys chaperi, Barbus ablabes, B. longipinnis, Hemichromis bimaculatus and Chromidotilapia guntheri) have high ETI and a cosmopolitan distribution in the Nero River. In the tributaries of the middle course, high concentrations of nitrite in the water, added to the presence of a lot of tolerant species in the ichthyofauna are indications of disturbance of these areas. Subsequent recommendations were formulated for efficient restoration and conservation management of this River.

    The purpose of this study was to determine the prevalence of tooth decay and its correlation with dental care habits in northwestern Ivory Coast. Study was carried out in primary schools in the city of Odienne in January 1999. The study cohort comprised 500 students of both genders ranging in age from 4 to 15 years. The prevalence of tooth decay was 77.2% and the mean CAO index was 2.43. Dental care involved use of a chewing stick in 49% and a tooth brush in 50.8%. Only 5.6% of children cleaned their teeth three-times a day on a regular basis. Statistical analysis of study data demonstrated a correlation between the frequency of tooth cleaning and incidence of tooth decay. The incidence of tooth decay was 60.7% in students that cleaned their teeth three times a day versus 78.2% in students who cleaned their teeth less regularly. An educational campaign has been undertaken to inform students of the importance of oral hygiene in maintaining healthy teeth. A dental examination program would be useful to provide routine check-ups. A group study will be needed to monitor oral hygiene in students and evaluate the impact of these measures on tooth decay.

    Full Text Available Long touted as an island of political stability and (relative economic prosperity in West Africa, since December 24, 1999, Côte d’Ivoire* has joined the more common category in the sub-region: praetorian states mired in political uncertainty and unending turbulence. Indeed, on September 19, 2002, it came very close to collapsing altogether, a fate very few would dare to predict only a few weeks earlier. This stunning evolution started with the military regime of General Robert Guei, which lasted less than ten months. Eric Nordlinger’s definition of praetorianism as “a situation in which military officers [in the case of Africa non-commissioned officers as well] are major or predominant political actors by virtue of their actual or threatened use of force” fits Ivory Coast perfectly today. Political violence has already claimed thousands of victims. As witnessed in the recent resumption of fighting and bloody upheaval, the threat to the country and the entire sub-region has by no means disappeared - despite the Marcoussis and Accra agreements and continued efforts to end the crisis.

    Full Text Available This study describes the intraspecific variation of 30 edible-seed Lagenaria siceraria germplasm accessions from the University of Abobo-Adjamé. These accessions were collected from three (Centre, East and South geographical zones of Côte d’Ivoire. Selection based on seed size by the farmers has resulted in subdividing the species into two cultivars: large-seeded and smallseeded. The morphological diversity study of the collection included 18 accessions and 24 traits. The multivariate analysis of variance (MANOVA showed a significant difference between the two groups of cultivars. Principal component analysis on 13 traits pointed out variations among individuals, mainly on the basis of flower, fruit, and seed size. Dendrogram with UPGMA method allowed clustering of the cultivars. The genetic structure analysis among accessions using allozyme markers showed the following values: 18.95% for the proportion of polymorphic loci (P, 1.21 for the number of alleles (A and 0.053 for observed heterozygosity (Ho. The level of the within accessions genetic diversity (HS = 0.188 was higher than the genetic variation among accessions (DST = 0.082. The estimates of F-statistics indicated a low level of genetic differentiation between accessions (FST = 0.298. Such a value suggested that L. siceraria maintains about 30% of its genetic variation among accessions. Nei genetic distances between the two cultivars were also low (0.002, indicating that cultivars were genetically similar enough to belong to the same genetic group.

    The central problem of the dosimetry of the ionizing radiations is the determination of the dissipated energy by unit of mass of irradiated material. This energy usually is inferred of ionization measures in a small cavity of air housed inside the material medium. The Bragg-Gray cavity theory was the first one in estimating the dissipated energy through the ionizations that the primary electrons cause in the cavity. The primary electrons are generated by photoelectric effect, pair production and by Compton dispersion of the photon beams that initially impact on the material. However, in a more realist approach the existence of secondary electrons due to the electron-electron interaction it will be considered. The Spencer-Attix cavity theory considers to the secondary electrons as responsible part for the energy deposited in the means, for that a total spectral fluence of electrons (primary and secondary) it appears in this theory. Few electrons spectra have been published, mainly, those that include the contribution of secondary electrons ({delta} rays). Leaving of the ideas of Spencer-Attix, in this work an approach method to determine the rate of electron spectral fluences (total regarding primary) for a wide variety of material Z, and energy sources T{sub 0} is presented. The method for materials used by Spencer-Attix is applied, it is proven its reliability and it is applied to the water like absorber medium by its importance in the clinical dosimetry. (Author)

    Full Text Available BACKGROUND: Health facility characteristics associated with effective prevention of mother-to-child transmission of HIV (PMTCT coverage in sub-Saharan are poorly understood. METHODOLOGY/PRINCIPAL FINDINGS: 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.

  16. Water saving through international trade of agricultural products

    Full Text Available Many nations save domestic water resources by importing water-intensive products and exporting commodities that are less water intensive. National water saving through the import of a product can imply saving water at a global level if the flow is from sites with high to sites with low water productivity. The paper analyses the consequences of international virtual water flows on the global and national water budgets. The assessment shows that the total amount of water that would have been required in the importing countries if all imported agricultural products would have been produced domestically is 1605 Gm3/yr. These products are however being produced with only 1253 Gm3/yr in the exporting countries, saving global water resources by 352 Gm3/yr. This saving is 28 per cent of the international virtual water flows related to the trade of agricultural products and 6 per cent of the global water use in agriculture. National policy makers are however not interested in global water savings but in the status of national water resources. Egypt imports wheat and in doing so saves 3.6 Gm3/yr of its national water resources. Water use for producing export commodities can be beneficial, as for instance in Cote d'Ivoire, Ghana and Brazil, where the use of green water resources (mainly through rain-fed agriculture for the production of stimulant crops for export has a positive economic impact on the national economy. However, export of 28 Gm3/yr of national water from Thailand related to rice export is at the cost of additional pressure on its blue water resources. Importing a product which has a relatively high ratio of green to blue virtual water content saves global blue water resources that generally have a higher opportunity cost than green water.

    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.

    OBJECTIVES: To study the tolerance and acceptability in Africa of a perinatal intervention to prevent vertical HIV transmission using benzalkonium chloride disinfection. DESIGN: A randomized, double blinded phase II trial. SETTING: Prenatal care units in Abidjan (Cote d'Ivoire) and Bobo-Dioulasso (Burkina Faso). PATIENTS: Women accepting testing and counselling who were seropositive for HIV-1 and under 37 weeks of pregnancy were eligible. A total of 108 women (54 in each group) enrolled from November 1996 to April 1997, with their informed consent. INTERVENTION: Women self administered daily a vaginal suppository of 1% benzalkonium chloride or matched placebo from 36 weeks of pregnancy, and a single intrapartum dose. The neonate was bathed with 1% benzalkonium chloride solution or placebo within 30 minutes after birth. MAIN OUTCOME MEASURES: Adverse events were recorded weekly, with a questionnaire and speculum examination in women through delivery, and examination of the neonate through day 30. The incidence of genital signs and symptoms in the women and cutaneous or ophthalmological events in newborns were compared between groups on an intent to treat basis. RESULTS: The median duration of prepartum treatment was 21 days (range 0-87 days). Compliance was 87% for prepartum and 69% for intrapartum treatment, and 88% for the neonatal bath, without differences between the two groups. In women, the most frequent event was leucorrhoea; the incidence of adverse events did not differ between treatment groups. In children, the incidence of dermatitis and conjunctivitis did not differ between the benzalkonium chloride and placebo groups (p = 0.16 and p = 0.29, respectively). CONCLUSION: Vaginal disinfection with benzalkonium chloride is a feasible and well tolerated intervention in west Africa. Its efficacy in preventing vertical HIV transmission remains to be demonstrated.

    Chairul A Nidom

    Full Text Available Ebola virus (EBOV and Marburg virus (MARV belong to the family Filoviridae and cause severe hemorrhagic fever in humans and nonhuman primates. Despite the discovery of EBOV (Reston virus in nonhuman primates and domestic pigs in the Philippines and the serological evidence for its infection of humans and fruit bats, information on the reservoirs and potential amplifying hosts for filoviruses in Asia is lacking. In this study, serum samples collected from 353 healthy Bornean orangutans (Pongo pygmaeus in Kalimantan Island, Indonesia, during the period from December 2005 to December 2006 were screened for filovirus-specific IgG antibodies using a highly sensitive enzyme-linked immunosorbent assay (ELISA with recombinant viral surface glycoprotein (GP antigens derived from multiple species of filoviruses (5 EBOV and 1 MARV species. Here we show that 18.4% (65/353 and 1.7% (6/353 of the samples were seropositive for EBOV and MARV, respectively, with little cross-reactivity among EBOV and MARV antigens. In these positive samples, IgG antibodies to viral internal proteins were also detected by immunoblotting. Interestingly, while the specificity for Reston virus, which has been recognized as an Asian filovirus, was the highest in only 1.4% (5/353 of the serum samples, the majority of EBOV-positive sera showed specificity to Zaire, Sudan, Cote d'Ivoire, or Bundibugyo viruses, all of which have been found so far only in Africa. These results suggest the existence of multiple species of filoviruses or unknown filovirus-related viruses in Indonesia, some of which are serologically similar to African EBOVs, and transmission of the viruses from yet unidentified reservoir hosts into the orangutan populations. Our findings point to the need for risk assessment and continued surveillance of filovirus infection of human and nonhuman primates, as well as wild and domestic animals, in Asia.

    The aim of this study was to assess the variability of the content of nutrients, oxidizable organic and particulate matters in raw sewage and the lagoon on the effect of rainfall. Then evaluate the impact of these changes in the concentration of enteroviruses (EVs) in waters. The sewage samples were collected at nine sampling points along the channel, which flows, into a tropical lagoon in Yopougon. Physical-chemical parameters (5-day Biochemical Oxygen Demand, Chemical Oxygen Demand, Suspended Particulate Matter, Total Phosphorus, Orthophosphate, Total Kjeldahl Nitrogen and Nitrate) as well as the concentration of EV in these waters were determined. The average numbers of EV isolated from the outlet of the channel were 9.06 × 104 PFU 100 ml-1. Consequently, EV was present in 55.55 and 33.33 % of the samples in the 2 brackish lagoon collection sites. The effect of rainfall on viral load at the both sewage and brackish lagoon environments is significant correlate (two-way ANOVA, P environment, nutrients (Orthophosphate, Total Phosphorus), 5-day Biochemical Oxygen Demand, Chemical Oxygen Demand and Suspended Particulate Matter were significant correlated with EVs loads ( P < 0.05 by Pearson test). The overall results highlight the problem of sewage discharge into the lagoon and correlation between viral loads and water quality parameters in sewage and lagoon.

    Full Text Available Preliminary observations of variability between some morphotypes of bambara groundnut (Vigna subterranea L. Verdc., Fabaceae from Côte d’Ivoire. Bambara groundnut (Vigna subterranea L. Verdc., is a food legume mainly cultivated by women for whom it represents a source of income for the household. In Côte d’Ivoire, the cultivation of bambara groundnut is located in the western and northern parts of the country. These zones are characterised by contrasted agroecology including tropical rain forest and dry savanna. In these zones, bambara groundnut plays a key role in both food and culture of peoples. Four morphotypes of Côte d’Ivoire (ICU, BPR, RBU, NFU were used in a preliminary study to assess the phenotypic variability between morphotypes. For each morphotype, 100 individuals were sampled to analyse 26 agromorphological traits selected from the list of bambara groundnut descriptors. Results of statistical analyses showed an important variability among morphotypes suggesting that 22 of these characters could be powerful to distinguish diversity among bambara groundnut morphotypes of Côte d’Ivoire. Three morphotypes (ICU, BPR and RBU show a shorter reproductive cycle than the other (NFU. In our experimental conditions, morphotypes with a shorter reproductive cycle give a higher percentage of matured pods (87 to 95%, compared to morphotype NFU (60%. The morphotype ICU was particularly earlier, maturing 90 days after sowing (DAS, whereas the long reproductive cycle morphotype (NFU required about 137 days. Based on the analysed agronomic traits, possibilities to improve bambara groundnut yield and to promote its cultivation in Côte d’Ivoire are discussed.

    Full Text Available Feeds Used in Semi-intensive-Fish Farming Systems and their productivity in Ivory Coast. A survey was carried out on fish feeds used in semi-intensive fish farming system in Ivory Coast. Fish feeds were collected from 156 fish farms. Their nutritional value and the factors affecting their use as well as their productivity were assessed. Commercial feeds, feeds produced by fish farmers and agro-industrial by-products were used respectively by 51%, 34%, and 47% of the producers, alone or mixed. Nutritional values of commercial feeds meet the nutritional requirement of fish breeding. Conversely, feeds produced by local feed sellers, fish farmers and agro-industrial by-products are in general poor in crude protein and/or rich in crude fiber. The geographical location of the fish farm, the age, the origin, the gender and the main professional activity of the fish farm owner influence the choice of feed. The highest growth parameters were obtained by the commercial feeds compared to fish farmer's feeds or agro-industrial byproducts. The average growth rates of tilapia range between 1.06 and 1.20 g/day. Their yields range between 2445 and 4252 kg/ha/year. The availability of low cost composed fish feeds which take into account the requirement of fish formulated from local and available raw materials would improve fish production.

    Full Text Available Continental Fish Farming in the Gontougo Area (Ivory Coast: Characterization and Socio-economic Aspects. This study aims at identifying the current state of fish farming in the area of Gontougo. It was carried out from May to September 2013 using a questionnaire and individual interview with fish farmers. The results showed that all producers practiced artisanal fish farming and this activity played an important socio-economic role. Fish farming is exclusively carried out by local people belonging mainly to the Abron ethnic group (77.8%. This activity is mainly practiced by people aged 45 years and over (77.8%. It was observed that 41.7% of the ponds are in derivation while 58.3% are barrage ponds. Oreochromis niloticus Linné, 1758 and Heterobranchus longifilis Valenciennes, 1840 are the most reared fish species. The total fish production in 2012 was estimated to 3,552.5 kg in 68 ponds. The produced quantities vary from a fish farmer to another, with an average production of 592.1±635.9 kg/fish farmer/year. All fish farmers (100% feed the fish with agricultural by-products. They have difficulties to feed them properly. They didn't receive funding, coaching and training. Some fish farmers (33.3% faced water problem. All these factors are an obstacle to sustainable management of fish farming in this area.

    Full Text Available Evolution of Fishing on Lake Ayame since the Deportation of Non National Fishermen. This study was conducted in all landing stages of man made lake Ayame in Ivory Coast. It's about assessing fishing activities a decade after the conflict between indigenous and non national fishermen who led to the final expulsion of the last one from that lake. For the data collecting a questionnaire survey was administered to fishers, and interviews were held with the lake manager, the administrative and custom authorities in the area of the lake. The results showed that since the expulsion of non national fishermen in 1998, the fishing is mainly done by indigenous with 69%. However, we notice the return of some alien with 10%. Regarding the fishing, fish production has decreased from 700 tons in 1998 to 516 tons in 2007. According to the distribution of catches by family and species, the cichlidae are the most catches with 52%. Tilapia Oreochromis niloticus which had nearly disappeared from the lake since 1998 with 3% to the benefit of tilapia Sarotherodon melanotheron with 51%, is reappearing with a proportion of 23% against 29% for second species cited. Regarding the average weight of fish caught, it has varied from 200 grams in 1998 to 400 grams in 2008 for the two main species fished.

    The aim of the presented study was to investigate the mycotoxin exposure of Ivorian population related to the consumption patterns of maize, peanuts, millet, and cassava product (attiéké). Maize flour samples (n = 51) were purchased from all Abidjan local markets, in the south of Ivory Coast, and urine (n = 99) was collected during the same reference period (July-September 2011) from volunteers living in Abidjan and Daloa cities. Reversed-phase liquid chromatography coupled with electrospray ionization triple quadrupole mass spectrometry (LC-ESI-MS/MS) was used to analyze aflatoxins (AFB1, AFB2, AFG1, and AFG2), ochratoxin A (OTA), fumonisins (FB1, FB2), deoxynivalenol (DON), zearalenone (ZEA), and T-2 and HT-2 toxins in maize flour samples, and their relevant biomarkers (AFM1, DON, DON + de-epoxydeoxynivalenol (DOM-1), FB1, α-zearalenol (ZOL), β-ZOL, and OTA) in urine samples. Critical maize contamination was observed by AFs occurrence (total AFs 4.5 - 330.0 μg/kg) while OTA was found in 13% of samples analyzed. AFM1 was detected in 40% of urines samples (0.06 - 14.11 ng/ml), OTA in 37% (0.01 - 0.42 ng/ml), FB1 in 27% (0.07 to 15.31 ng/ml) and, DON was found in 21% of samples at levels up to 10.0 ng/ml. The correlation coefficients (R(2)) obtained by plotting the percentage of biomarker occurrence (positive samples) versus the frequency of food consumption revealed maize, peanuts, millet and attiéké were strongly linked to AFB1 and OTA exposure with values of R(2) ranged from 0.462 to 0.956. The present study provided data on mycotoxin risk in Ivory Coast, revealing a frequent co-exposure to the major mycotoxins such as AFs, OTA, and fumonisins, which appeared to be related to the frequency of peanuts, maize, millet and attiéké consumption.

Distichodus rostratus (Günther, 1864 is a commercially important species but its reproductive biology is not well known. Reproductive cycle and fecundity of D. rostratus from the Bandama river have been studied for a year (July 2004 to June 2005. The spawning period was determined by analyzing the monthly evolution of the gonado-somatic index (GSI. The liver-somatic index (LSI and the condition factor (Kc were calculated and the corresponding curves were fitted. The degree of maturity was determined using macroscopic observation of the gonads. The percentage of mature specimens by sexes was calculated for each size class. However, the first size of maturity was determined by using a logistic function. Sex-ratio (1:1.61 observed was in favour of females. Standard length at first maturity was 39.6 cm for males and 46,3 cm for females. The ripe ovaries contained 81,048-100,747 eggs. The relative fecundity was 12,004 eggs per kg of body weight. The mean size of eggs was 1.19 mm. The GSI indicated a spawning period going from August to October. In this period, when GSI is high, LSI decreases. This can be explained by the use of the liver reserves for developing the gonads.

    Full Text Available Diffuse large B-cell lymphomas have been little studied in black Africans. The purpose of our study was to determine the characteristics and results of the management of these lymphomas. Patients and Methods. In a descriptive and analytic retrospective study we studied the medical records of 63 patients with diffuse large B-cell lymphoma hospitalized during the period from 1991 to 2007. The diagnosis was made after lymph node or organ biopsy. Response to treatment, OS, PFS, and toxicity were studied. The complete response has been analyzed univariate and multivariate analysis. Results. The median age was 42 years. The sex ratio was 2. The HIV serology was positive in 11 cases, and 8 patients had antiretroviral therapy. In 71% the lymphoma was at stages III and IV of Ann Arbor. IPI was ≥3 in 65%. Complete remission was achieved in 43%. Only 43% of patients had had a good compliance. Progression-free survival at 3 years was 32%, and overall survival at 3 years was 50%. 13% of patients were lost to follow up, and 51% of them died. In terms of analysis the complete remission rate was influenced by the stage of Ann Arbor (<0.0001, biological b symptoms (<0.01, the IPI (<0.0001, and the socioeconomic standing (=0.001. In multivariate analysis, only IPI and stage of Ann Arbor influence the complete remission.

    Despite precautions taken to guarantee blood safety, in the National Blood Transfusion Center (CNTS) of Abidjan, about 30 regular blood donors are detected with HIV seroconversion each year, two-thirds of them men. A survey through face-to-face interviews was carried out at the CNTS of Abidjan from September 2001 to March 2002 among HIV-positive and HIV-negative regular blood donors, informed about their serologic status. HIV-negative regular blood donors informed about their serologic status since a median time of 67 months (n = 50) disclosed more risky behaviors such as multiple sexual partners (68%) than HIV-positive blood donors informed about their status (n = 112) since a median time of 35 months (41%) (P < 0.001). Condoms were systematically used by 17% of HIV-negative blood donors and 55% of HIV-positive blood donors (P < 0.001). Enhanced counseling and awareness could reduce in the future the number of cases of seroconversion among regular blood donors and improve their subsequent behavior. Blood donors who have unprotected sex with partners of unknown HIV serologic status and especially with casual partners are strongly exposed to HIV transmission and should be discouraged to continue giving blood, after adequate counseling.

    To report the tolerance of indinavir combined with ritonavir (IDV/r 800/100 mg) twice daily (bid) in sub-Saharan African HIV-infected adults. HAART-naives patients started zidovudine plus lamivudine plus IDV/r 800/100 mg bid. Follow-up included standardized documentation of morbidity, CD4(+) cell count, creatininemia, plasma HIV-1 RNA, and IDV minimal plasma concentration (C(min)) measurements at month 1 (M1), M3, and M6. Seventy HIV-1-infected adults (68 women, median CD4 235/mm(3)) started HAART. At M6, 63% had undetectable viral load, and the median gain in CD4 since baseline was +128/mm(3). During the first 6 months, 21 patients experimented with 23 treatment modifications (reduction in IDV/r 400/100 mg bid, n = 11; switch to efavirenz, n = 11; zidovudine replaced by stavudine, n = 1), including 22 for digestive intolerance and 1 for severe anemia. At M1, M3, and M6, 67, 59, and 48 patients were still receiving IDV/r 800/100 mg bid, of whom 70%, 72%, and 60% had IDV Cmin above 5 ng/ml, respectively. In these patients, at M1, M3, and M6, the mean (+/- SD) IDV C(min) were 3431 +/- 3835 ng/ml, 2288 +/- 2116 ng/ml, and 1543 +/- 2398 ng/ml, respectively. There was no renal insufficiency of any grade, and no symptoms of urinary stones. The IDV/r 800/100 mg bid-containing regimen led to high IDV Cmin and a high rate of digestive intolerance. There was a surprising lack of nephrological side effects during the 6 months of follow-up, supporting the hypothesis that nephrological tolerance of IDV might be higher in sub-Saharan African individuals than in Americans or Europeans.

    BACKGROUND: Cotrimoxazole prophylaxis has an antimalarial effect which could have an additional protective effect against malaria in HIV-infected children on antiretroviral therapy (ART). We measured the incidence and associated factors of malaria in HIV-infected children on ART and...... classified as confirmed or probable malaria. We calculated incidence density rates (IR) per 100 child-years (CY). Risk factors were assessed using a Poisson regression model. RESULTS: Overall, 1117 children were included, of whom 89 % were ART-treated and 67 % received cotrimoxazole. Overall, there were 51...... malaria events occurring in 48 children: 28 confirmed and 23 probable; 94 % were uncomplicated malaria. The overall IR of malaria (confirmed and probable) was 18.3/100 CY (95 % CI: 13.3-23.4), varying from 4.2/100 CY (95 % CI: 1.1-7.3) in children on ART and cotrimoxazole to 57.3/100 CY (95 % CI: 7...

    Introduction. Surgical treatment of perforated peptic ulcer (PPU) is a challenge for surgeons in Africa. Aim. To determine risk factors of postoperative complications or mortality among black Ivoirian patients with PPU. Methods. All 161 patients (median age = 34 years, 90.7 male) operated on for PPU in the visceral and general surgery unit were enrolled in a retrospective cohort study. Variables were studied with Kaplan Meier and Cox proportional hazard models. Results. Among 161 patients operated on for PPU, 36 (27.5%) experienced complications and 31 (19.3%) died. Follow-up results were the incidence of complications and mortality of 6.4 (95% CI: 4.9–8.0) per 100 person-days and 3.0 (95% CI: 1.9–4.0) per 100 person-days for incidence of mortality. In multivariate analysis, risk factors of postoperative complications or mortality were comorbidities (HR = 2.1, P = 0.03), tachycardia (pulse rate > 100/minutes) (HR = 2.4, P = 0.02), purulent intra-abdominal fluid collection (HR = 2.1, P = 0.04), hyponatremia (median value ≤ 134 mEq/L) (HR = 2.3, P = 0.01), delayed time of hospital admission > 72 hours (HR = 2.6, P < 0.0001), and delayed time of surgical intervention between 24 and 48 hours (HR = 3.8, P < 0.0001). Conclusion. The delayed hospital admission or surgical intervention and hyponatremia may be considered as additional risk of postoperative complications or mortality in Black African patients with PPU.

    The lack of data on neonatal tetanus and children in university hospitals (UH) in Abidjan for over a decade has motivated the realization of this study. The objective of this study is to evaluate the morbidity and mortality related to neonatal tetanus (NT) and child tetanus (CT) in Abidjan University Hospital from 2001 to 2010. It is a retrospective study, multicenter analysis with records of newborns and children suffering from tetanus in the three UH of Abidjan. The collection and analysis of data were made by the SPHINX 4.5 and EPI.INFO 6.0 software. In ten years, 242 cases of tetanus (53 NT cases and 189 CT cases) were collected with a predominance of cases after the fifth year of life (59.5%). The incidence rate of NT was less than 1 case per 1,000 live births. All mothers of the newborns were inhabiting the city of Abidjan. Their median age was 19 years [16-32] and 64% were teenagers. Gateways were dominated by umbilical wounds (77.3%) in the NTand skin wounds (59%) in CT. The cure rate was 30.2% in the NT and 60% in the CT. Lethality was 60% for NT and 22% for CT with a positive correlation with young age (neonates: p = 4.10-7, age <5 years: p = 0.01), lack of intraspinal injection of tetanus serum (p = 8.10-6), the absence of conventional antibiotic therapy (p = 0.023), the existence of metabolic complications (p = 2.10-5), the score of ≥ 4 Dakar (p = 0.005). Tetanus remains a real morbidly cause among children in Abidjan University Hospital with high lethality. However, the incidence of NT seems consistent with the incidence threshold desired by WHO.

    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.

    Full Text Available Physico-chemical Properties of Starch from Ginger Rhizome (Zingiber officinale roscoe of Ivory Coast. The ginger or rhizome of Zingiber officinale roscoe is one of spice valued for its characteristic aroma and pungency. It grows in tropical region, specially in south and east part of Asia. That spice in commercialised in dry form. In Ivory Coast, the ginger is often consumed in the form of drink commonly called "Gnamakoudji". In order to increase the value of ginger, studies about the physico-chemical and functional properties of ginger starch have been investigated. Its amylose, ash, lipid and protein content are respectively 28.3%, 0.14%, 0.12% and 0.18%. The granule size is between 6.43 and 38.56 μm. Native ginger starch shows a very low sensitiveness to snail's digestive sap, on the other hand, gelatinized starch is very sensitive. Acid hydrolysis gave two phases: a fast one during the first fortnight and a slow one beyond. The swelling and solubility study has revolted a weak swelling power and a low solubility in water. The thermogram showed a high gelatinization temperature in order of 83.2 °C and a gelatinization enthalpy of 14.65 J/g. Retrogradation study reveals that starch retrogrades at the end of two days and at J0, syneresis is 44% and clarity is 11.5%.

Within the biocoenosis of cassava mealybug, Phenacoccus manihoti, in Ivory Coast, the presence of many predator and parasite insects is reported. The main predators of the mealybugs are Coccinellidae and particularly Scymnus couturieri. Among parasites, the most numerous are Encyrtidae hymenoptera. Some, like Epidinocarsis lopezi, attack directly mealybugs and are thus useful assistants. Others live as parasite on predators or parasites of mealybugs and so reduce the efficiency of those assistants. In addition, some other insects are present, whose role is not known. The authors note the relative abundance of all the collected species.

The work was performed on 71 wells in February 2012 (dry season and June 2012 (rainy season. Groundwater levels and physico-chemical parameters (pH, temperature, electrical conductivity, redox potential (Eh, Total Dissolved Solid (TDS and Salinity were measured to assess the water table fluctuation and the groundwater quality. Standardized Principal Component Analysis (SPCA was calculated to group the well waters and to evaluate their suitability for drinking according to different classes. Water table varies between 125 and 135 m during the dry season and between 127 and 136 m during the rainy season with a West-Est flow direction. The recharge values ranged between 0.57 m and 5.57 m. Wells waters are generally acidic (pH<6.5, high mineralized with conductivities and Total Dissolved Solids (TDS respectively above 600 µS/cm and 300 mg/l. Well water salinity values ranged between 0.30 and 0.5%. The Standardized Principal Component Analysis (SPCA allowed distinguishing three important groups of water within M’bahiakro area: the first group of wells with high mineralized water, the second group of wells with high potential redox (Eh and the third group of wells with pH closer to neutral. The first and second groups are not very suitable for drinking because they are suspected of being contaminated by anthropogenic sources such as septic tanks and wild dump. Waters of these wells need to be treated before any domestic use.

    Landslides, a natural phenomenon often enhanced by human misuse of the land, may be a considerable threat to urban communities and severely affect urban landscapes, taking its death toll, impacting livelihood, and causing economic and social damages. Our first results show that, in Abidjan city, Ivory Coast, landslides caused more than fifty casualties in the towns of Attecoube and Abobo during the last twenty years. Although informal landslide reports exist, map information and geomorphological characterization are at best restricted, or often simply lacking. Here, we aim at constituting a comprehensive landslide database (localization, nature and morphometry of the slides, slope material, human interference, elements at risk) in the town of Attecoube as case study in order to support a first analysis of landslide susceptibility in the area. The field inventory conducted so far contains 56 landslides. These are mainly translational debris and soil slides, plus a few deeper rotational soil slides. Affecting 10-25°-steep, less than 10-m-high slopes in Quaternary sand and mud, they are most often associated with wild constructions either loading the top or cutting the toe of the slopes. They were located by GPS and tentatively dated through inquiries during the survey. While 12 landslides were accurately dated that way from the main rain seasons of 2013 to 2015, newspapers analysis and municipal archive consultation allowed us to assign a part of the rest to the last decade. Field inquiries were also used to collect information about fatalities and the local conditions of landsliding. This first landslide inventory in Attecoube provides clues about the main potential controls on landsliding, natural and anthropogenic, and will help define adequately anthropogenic variables to be used in the susceptibility modelling.

    Background Access to useful plants is a growing problem in Africa, increased by the loss of natural vegetation and the erosion of traditional knowledge. Ethnobotany contributes to promote these indigenous knowledge. Despite the large diversity of ethnic groups in Côte d’Ivoire, few ethnomedicine researches have targeted these groups. Among the great Akan group, the Ehotile people are one of the smallest and oldest ethnic group around the Aby Lagoon. The goal of this study was to analyze the l...

    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.

    Attitudes toward and approaches to error in language learning depend on one's point of view: strictly linguistic, pedagogical, or that of the learner. This last approach is that "one learns by making mistakes," and from that perspective, there is no absolute definition of error, but only an operative one. (MSE)

A total of 329 Triatoma infestans were captured, 293 on 4 terraces of seven-floor-towers and 36 inside the winery, associated with the great number of pigeons which nest in those places. The bugs were sheltered in the dung accumulated between the cement blocks used to floor the terraces and inside the unused tuns in the winery. Two main bug foci were identified associated with the dense pigeon colonies: 81,5% of the T. infestans collected were found in one of the towers (4B and 11% in the central winery. After six months of insecticidal sprayind of the infested areas, those terraces in wich T. infestans had not been previously found resulted gave positive results. The feeding profile of triatomines shows a predominance of simple bird blood meals; in the buildings and the winery 95% of the T. infestans analized were identified for bird blood meals; the rest had fed on one or more sources: human, dogs or cats. None of the T. infestans was infected by T. cruzi.

    Full Text Available Abstract The objective of this paper was to present the factors that impede the implementation of ISO 9000 QMS within the manufacturing and service Industry of Ivory Coast. It wasnt the intention of the author to provide detailed strategies for the readers to implement ISO 9000. It was an effort to present the relationship if any between the lack of ISO 9000 adoption and the perception of Ivoirians business organization leaders. For that purpose five research questions were associated with this study. The population for this study was all non-ISO certified business organizations in both public and private sector and was physically located in Ivory Coast. The population sample for this study was the 5044 members of the Chambre de Commerce et dIndustrie de Cote dIvoire CCI from which the author utilized the sample size of 60 business organizations randomly selected. This study utilized a survey questionnaire of face to face interview as data collection method. The survey questionnaire contained thirty three 33 questions organized in six parts and was proposed to 60 business organizations leaders. The result showed that business organization leaders in Ivory Coast were aware of the ISO 900 QMS but do not have enough knowledge on the ISO 9000 QMS implementation and certification. This could be due to the poor job done by CODIMORM the local national bureau of standards as a source of information. However it was found that business organization leaders in Ivory Coast intended to pursue and obtain ISO 9000 QMS certification. With respect to perceived benefits they indicated customer satisfaction improvement as the most important benefit that ISO 9000 QMS certification could bring to their general management activities. With respect to perceived improvements they selected quality of productsservices as the most important improvement that ISO 9000 QMS implementation and certification could help to achieve.

    The taxonomy of the family Filoviridae (marburgviruses and ebolaviruses) has changed several times since the discovery of its members, resulting in a plethora of species and virus names and abbreviations. The current taxonomy has only been partially accepted by most laboratory virologists. Confusion likely arose for several reasons: species names that consist of several words or which (should) contain diacritical marks, the current orthographic identity of species and virus names, and the similar pronunciation of several virus abbreviations in the absence of guidance for the correct use of vernacular names. To rectify this problem, we suggest (1) to retain the current species names Reston ebolavirus, Sudan ebolavirus, and Zaire ebolavirus, but to replace the name Cote d'Ivoire ebolavirus [sic] with Taï Forest ebolavirus and Lake Victoria marburgvirus with Marburg marburgvirus; (2) to revert the virus names of the type marburgviruses and ebolaviruses to those used for decades in the field (Marburg virus instead of Lake Victoria marburgvirus and Ebola virus instead of Zaire ebolavirus); (3) to introduce names for the remaining viruses reminiscent of jargon used by laboratory virologists but nevertheless different from species names (Reston virus, Sudan virus, Taï Forest virus), and (4) to introduce distinct abbreviations for the individual viruses (RESTV for Reston virus, SUDV for Sudan virus, and TAFV for Taï Forest virus), while retaining that for Marburg virus (MARV) and reintroducing that used over decades for Ebola virus (EBOV). Paying tribute to developments in the field, we propose (a) to create a new ebolavirus species (Bundibugyo ebolavirus) for one member virus (Bundibugyo virus, BDBV); (b) to assign a second virus to the species Marburg marburgvirus (Ravn virus, RAVV) for better reflection of now available high-resolution phylogeny; and (c) to create a new tentative genus (Cuevavirus) with one tentative species (Lloviu cuevavirus) for the recently

    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.

  9. Revisiting sub-Saharan African countries' drug problems: health, social, economic costs, and drug control policy.

    Affinnih, Yahya H

    2002-02-01

    This article takes an international perspective on the drug problem in sub-Saharan Africa. This analysis borrows ideas from physical and economic geography as a heuristic device to conceptualize the global narcoscapes in which drug trafficking occurs. Both the legitimate and the illegal drug trade operate within the same global capitalist system and draw on the same technological innovations and business processes. Central to the paper's argument is evidence that sub-Saharan African countries are now integrated into the political economy of drug consumption due to the spill-over effect. These countries are now minor markets for "hard drugs" as the result of the activities of organizations and individual traffickers that use Africa as a staging point in their trade with Europe and the United States. As a result, sub-Saharan African countries have drug consumption problems that were essentially absent prior to 1980, along with associated health, social, and economic costs. The emerging drug problem has forced African countries to develop their own drug control policy. The sub-Saharan African countries mentioned below vary to some extent in the level of drug use and misuse problems: Burundi, Comoros, Djibouti, Eritrea, Ethiopia, Kenya, Madagascar, Malawi, Mauritius, Mozambique, Reunion, Rwanda, Seychelles, Somalia, Tanzania, Uganda, Zambia, Angola, Cameroon, Central African Republic, Chad, Congo, Congo (Zaire), Equatorial Guinea, Gabon, Sao Tome and Principe, Botswana, Lesotho, Namibia, South Africa, Swaziland, Benin, Burkina Faso, Cape Verde, Cote d'Ivoire, Gambia, Ghana, Guinea, Guinea Bissau, Liberia, Mali, Mauritania, Niger, Nigeria, Senegal, Sierra Leone, and Togo. As part of this effort, African countries are assessing the health, social, and economic costs of drug-use-related problems to pinpoint methods which are both effective and inexpensive, since their budgets for social programs are severely constrained. Many have progressed to the point of adopting anti

    Background In resource-limited countries, estimating CD4-specific incidence rates of mortality and morbidity among patients receiving antiretroviral therapy (ART) may help assess the effectiveness of care and treatment programmes, identify program weaknesses and inform decisions. Methods We pooled data from 13 research cohorts in five sub-Saharan African (Benin, Burkina Faso, Cameroon, Cote d'Ivoire and Senegal) and two Asian (Cambodia and Laos) countries. HIV-infected adults (≥18 years) who received ART in 1998-2008 and had at least one CD4 count available were eligible. Changes in CD4 counts over time were estimated by a linear mixed regression. CD4-specific incidence rates were estimated as the number of first events occurring in a given CD4 stratum divided by the time spent within the stratum. Results Overall 3,917 adults (62% women) on ART were followed-up during 10,154 person-years. In the ≤50, 51-100, 101-200, 201-350, 351-500, 501-650 and >650/mm3 CD4 cells strata, death rates were: 20.6, 11.8, 6.7, 3.3, 1.8, 0.9 and 0.3 per 100 person-years; AIDS rates were: 50.5, 32.9, 11.5, 4.8, 2.8, 2.2 and 2.2 per 100 person-years; and loss to follow-up rates were: 4.9, 6.1, 3.5, 3.1, 2.9, 1.7 and 1.2 per 100 person-years, respectively. Mortality and morbidity were higher during the first year following ART initiation. Conclusion In these resource-limited settings, death and AIDS rates remained substantial after ART initiation, even in individuals with high CD4 cell counts. Ensuring earlier ART initiation and optimizing case finding and treatment for AIDS-defining diseases should be seen as priorities. PMID:23274931

    Elise Arrivé

    Full Text Available OBJECTIVE: We assessed the effect of HIV status disclosure on retention in care from initiation of antiretroviral therapy (ART among HIV-infected children aged 10 years or more in Cote d'Ivoire, Mali and Sénégal. METHODS: Multi-centre cohort study within five paediatric clinics participating in the IeDEA West Africa collaboration. HIV-infected patients were included in this study if they met the following inclusion criteria: aged 10-21 years while on ART; having initiated ART ≥ 200 days before the closure date of the clinic database; followed ≥ 15 days from ART initiation in clinics with ≥ 10 adolescents enrolled. Routine follow-up data were merged with those collected through a standardized ad hoc questionnaire on awareness of HIV status. Probability of retention (no death or loss-to-follow-up was estimated with Kaplan-Meier method. Cox proportional hazard model with date of ART initiation as origin and a delayed entry at date of 10th birthday was used to identify factors associated with death or loss-to-follow-up. RESULTS: 650 adolescents were available for this analysis. Characteristics at ART initiation were: median age of 10.4 years; median CD4 count of 224 cells/mm³ (47% with severe immunosuppression, 48% CDC stage C/WHO stage 3/4. The median follow-up on ART after the age of 10 was 23.3 months; 187 adolescents (28.8% knew their HIV status. The overall probability of retention at 36 months after ART initiation was 74.6% (95% confidence interval [CI]: 70.5-79.0 and was higher for those disclosed compared to those not: adjusted hazard ratio for the risk of being death or loss-to-follow-up = 0.23 (95% CI: 0.13-0.39. CONCLUSION: About 2/3 of HIV-infected adolescents on ART were not aware of their HIV status in these ART clinics in West Africa but disclosed HIV status improved retention in care. The disclosure process should be thus systematically encouraged and organized in adolescent populations.

    The Millennium Development Goals are now replaced by 17 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 undernutrition among children living in households with the improved sources of water, sanitation, and non-solid cooking fuel. Two sources of information are 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 (DHS) performed in the countries of Sub-Saharan Africa and South Asia after 2010 was included in the study. It resulted in the inclusion of 15 countries which were Bangladesh (2011), Congo Republic (2013-2014), Cote d'Ivoire (2011-2012), Ethiopia (2011), Gambia (2013), Mali (2012-2013), Mozambique (2011), Namibia (2013), Nepal (2011), Niger (2012), Nigeria (2013), Pakistan (2012-2013), 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 DHSs. 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 undernutrition among children aged 12-59 months. The risks were

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. Age and baseline clinical state had no significant influence on immunological response.Conclusion: The relationship between adherence and CD4

The ecology of Polynemids (Poydactylus quadrifilis, Galeoides decadactylus and Pentanemus quinquarius has been studied starting from the unloads of the artisanal marine fisheries of Grand Lahou (Ivory Coast. The temperature of the littoral is high during June and May with an average of 27,55±0,8 °C such as between November and December (29,30±0,1 °C. It is low between July and September (24,5±1,5 °C. On the other hand, salinity has its higher average values (35±0,8 g/l during the cold periods (July at September and lowest during the hot period, from October to January (33,9±0,3 g/l. The physiological needs of Polynemids cause seasonal migrations of the juveniles and adults. Hence the crossing of the estuary of the lagoon during the cold period, from June to August by the juveniles of Polydactylus quadrifilis and Galeoides decadactylus. For Polydactylus quadrifilis the annual recruitment of young specimens is identical to that of the adults, which is contrary to that of Galeoides decadactylus and Pentanemus quinquarius.

In order to determine the substratum inducing the best performances of growths, all the individuals were fed a concentrated food with 14.01% of calcium. This study revealed that the quality of the substratum influences the parameters of growth of A. ventricosa. The best growth was obtained on the substratum S3 (0.284 g/j; 0.169 mm/j. The substrata S2 and S4 support a similar growth to the pilot substratum (S5. The sawdust thus supports a better growth of A. ventricosa and could then be advised as source of amendment of the substrata to whoever would like to make the breeding of this specie.

Our objective was to assess response to imatinib mesylate (Glivec in Côte d’Ivoire patients with newly diagnosed Chronic Myeloid Leukemia (CML. From May 2005 to September 2009, we treated 42 patients (40 years; range 16–69 with Philadelphia chromosome (Ph+ positive in chronic phase CML with oral imatinib mesylate at daily doses of 400 mg. Overall survival (OS and frequency of complete or major cytogenetic remission (CCR/MCR were evaluated. At a median follow up of 32 (range 7.6–113 months, the CHR rate in our study group was 76%. A major CR was found in 19 patients (45% with 17% and 29% complete and partial CR respectively. There were no significant differences in the incidence of major cytogenetic response by known prognostics factors. Median time to CHR was 8 months (range 0.4–25, and 16 months (range: 0.1–36 for CR. Projected 5-year OS rate was 72% (95%CI 42–88. We conclude that imatinib therapy sub-Saharan African CML patients is very promising and has favorably changed the prognosis for black African patients with CML.

    Full Text Available Abstract Background Drug resistance in Plasmodium falciparum poses a major threat to malaria control. Combination anti-malarial therapy, including artemisinins, has been advocated to improve efficacy and limit the spread of resistance. The fixed combination of oral artemether-lumefantrine (AL is highly effective and well-tolerated. Artemisinin/naphtoquine (AN is a fixed-dose ACT that has recently become available in Africa. The objectives of the study were to compare the efficacy and safety of AN and AL for the treatment of uncomplicated falciparum malaria in a high transmission-intensity site in Ivory Coast. Methods We enrolled 122 participants aged 6 months or more with uncomplicated falciparum malaria. Participants were randomized to receive either artemisinin/naphtoquine or artemether/lumefantrine with variable dose according to their weight. Primary endpoints were the risks of treatment failure within 28 days, either unadjusted or adjusted by genotyping to distinguish recrudescence from new infection. Results Among 125 participants enrolled, 123 (98.4% completed follow-up. Clinical evaluation of the 123 participants showed that cumulative PCR-uncorrected cure rate on day 28 was 100% for artemisinin/naphtoquine and 98.4% for artemether/lumefantrine. Both artemisinin-based combinations effected rapid fever and parasite clearance. Interpretation These data suggest that Arco® could prove to be suitable for use as combination antimalarial therapy. Meanwhile, pharmacokinetic studies and further efficacy assessment should be conducted before its widespread use can be supported.

    Taro (Colocasia esculenta cv fouê) corm was subjected to different boiling times and the changes in chemical composition and physico-functional properties were investigated using standard method. The change in boiling time led to a significant (P < 0.05) reduction in the moisture, reducing sugars, total sugars, crude fat, crude fibre, total phenolic compound contents and iodine affinity of starch, whereas the total carbohydrate content, water absorption capacity, water solubility index, paste clarity and foam capacity increased significantly (p < 0.05). The crude protein and total ash contents of the flours from taro corm were not affected significantly (p < 0.05) by the change in boiling time. Taro corm flours exhibited highest total carbohydrate, crude fibre, total ash contents, water absorption capacity, iodine affinity of starch and lowest crude protein and fat contents, foaming capacity and water solubility index. Principal component analysis showed that flours from taro corm boiled during 20 min and 15 min were located at the left of the score plot, while flours from raw and boiled taro corm during 10 min had a large positive score in the first principal component.

Les méthodes statistiques indiquent des ruptures entre 1966 et 1981, qui marquent une modification des régimes pluviométrique et hydrologique. Ces ruptures s'accompagnent d'une diminution de la pluviométrie de 13 à 28 % et de l'écoulement du Bandama de 58 %. Les manifestations de cette variabilité climatique se répercutent sur les ressources en eau souterraine.

    The effect of coffee cherries quantity put out for sun drying on the kinetics of the drying, chemical components variation, fungal growth and ochratoxin A production was evaluated. The results showed that the more coffee cherries quantity on the drying area was important, the slower they dried. Indeed, the drying durations were 12, 17, 21, 26, 31 and 32 days respectively for the lots of 10 kg, 20 kg, 30 kg, 40 kg, 50 kg and 60 kg of cherries by square meter of drying area. The slowness of the drying led to the increasing of fungal development and ochratoxin A production in the cherries. Indeed, samples more contaminated were those from the lots of 50 kg and 60 kg of cherries by square meter of drying area with between 10% and 100% of infected beans and with levels of ochratoxin A ranging from 0.92 to 118.47 and 1.4 to 131.33 μg kg(-1) respectively. The slowness of the drying led also to the acidification of the cherries (pH=5.55-4.54) and the degradation of their chlorogenic acids content (13.03-11.69) while for their caffeine content (2.52-2.54), any significant difference was observed whatever the drying duration.

The effect of stimulating paste quantity appeared significantly at the production level, in the ratio of the yield improvement and in the residual of Ethrel (which persists the first fifth tapping after stimulation. Hevea productivity is generally correlated to the length of tapping cut. However, after stimulation, the inverse tendency was observed, short tapping cuts becomed more efficient. The quantifies of stimulating paste 0, 65 and 1 g which gave best result could be retained for clones GT 1 and PB 217. The results of this study showed that the reduction of stimulating paste quantity is justified for clone GT 1 but there is adequation between production and quantity of stimulating paste preconised in case of clone PB 217. This confirms the difference of metabolic activity between the two clones studied.

    Résumé Problème: Le dépistage VIH chez les enfants a rarement été au centre des préoccupations des chercheurs. Quand le dépistage pédiatrique a retenu l'attention, cela a été pour éclairer seulement sur les performances diagnostiques en ignorant même que le test pédiatrique comme bien d'autres peut s'accepter ou se refuser. Cet article met au cœur de son analyse les raisons qui peuvent expliquer qu'on accepte ou qu'on refuse de faire dépister son enfant. Objectif: Etudier chez les parents, les mères, les facteurs explicatifs de l'acceptabilité du test VIH des nourrissons de moins de six mois. Méthodes: Entretien semi-directif à passages répétés avec les parents de nourrissons de moins de six mois dans les formations sanitaires pour la pesée/vaccination et les consultations pédiatriques avec proposition systématique d'un test VIH pour leur nourrisson. Résultats: Nous retenons que la réalisation effective du test pédiatrique du VIH chez le nourrisson repose sur trois éléments. Primo, le personnel de santé par son discours (qui dénote de ses connaissances et perceptions même sur l'infection) orienté vers les mères influence leur acceptation ou non du test. Secundo, la mère qui par ses connaissances et perceptions même sur le VIH, dont le statut particulier, l'impression de bien-être chez elle et son enfant influence toute réalisation du test pédiatrique VIH. Tertio, l'environnement conjugal de la mère, particulièrement caractérisé par les rapports au sein du couple, sur la facilité de parler du test VIH et sa réalisation chez les deux parents ou chez la mère seulement sont autant de facteurs qui influencent la réalisation effective du dépistage du VIH chez l'enfant. Le principe préventif du VIH, et le désir de faire tester l'enfant ne suffisent pas à eux seuls pour aboutir à sa réalisation effective, selon certaines mères confrontées au refus du conjoint. A l'opposé, les autres mères refusant la réalisation du test pédiatrique disent s'y opposer ; bien entendu, même dans le cas où le conjoint l'accepterait. Discussion: Les mères sont les principales mises en cause et craignent les réprimandes et la stigmatisation. Le père, le conjoint peut être un obstacle, quand il s'oppose au test VIH du nourrisson, ou devenir le facilitateur de sa réalisation s'il est convaincu. Le positionnement du père demeure donc essentiel dans la question de l'acceptabilité du VIH pédiatrique. Les mères en ont conscience et présagent des difficultés à faire dépister ou non les enfants sans avis préalable du conjoint à la fois père, et chef de famille. Conclusion: La question du dépistage pédiatrique du VIH, au terme de notre analyse, met en face trois éléments qui exigent une gestion globale pour assurer une couverture effective. Ces trois éléments n'existeraient pas sans s'influencer, donc ils sont constamment en interaction et empêchent ou favorisent la réalisation ou non du test pédiatrique. Aussi, dans une intention d'aboutir à une couverture effective du dépistage VIH des nourrissons, faut-il tenir compte d'une gestion harmonieuse de ces trois éléments: La première, la mère seule (avec ses connaissances, ses perceptions), son environnement conjugal (de proposition du test intégrant 1- l’époux et / ou père de l'enfant avec ses perceptions et connaissances sur l'infection 2- la facilité de parler du test et sa réalisation chez les deux ou un des parents, la mère) et les connaissances, attitudes et pratiques du personnel de l’établissement sanitaire sur l'infection du VIH. Recommandations: Nos recommandations proposent une redéfinition de l'approche du VIH/sida vers des familles exposées au VIH et une intégration plus accentuée du père facilitant leur propre acceptation du test VIH et celle de leur enfant.

This study aimed at determining the socio­economic roles, the traditional management practices, and the production constraints of the Baoulé cattle. It was conducted in Bounkani region of North­Eastern Ivory Coast, using a semi­structured questionnaire. The results indicate that most (62.7 percent of the respondents depended on crop and livestock production for household income and food security. Farmers of this region (60 percent use the Baoulé cattle owing to their multiple socio­economic functions, adaptive qualities, and low management requirements. The Baoulé cattle are primarily reared for ritual ceremonies, gifts and as security against the vicissitudes of life. Farmers (98.41 percent use natural pasture without supplementation. In the North ­ Eastern of Ivory Coast, livestock rearing tends to be made according to the demand of zebu cattle, due to the secondary interest given to Baoulé cattle. This leads Lobi farmers to breed Baoulé with zebu cattle and to invest in the health of animals because Zebu and cross­bred Zebu x Baoulé are more sensitive than the Baoulé cattle to animal trypanosomiasis. In view of the multiple functions of Baoulé cattle, their specific genetic characteristics and the threat of absorption hanging over it, this local resource should be preserved and valued for its sustainable utilization.

    Full Text Available La relation pluie-débit fait l'objet de nombreuses études, à cause de son importance dans la mise en œuvre de nombreux projets de développement. La communauté scientifique, dans le souci de faire face aux problèmes d'eau, tels que les inondations et les sècheresses, utilise différents modèles. Mais ces modèles sont généralement confrontés à la non-linéarité de la relation pluie-débit. Dans le cas du Bandama Blanc, objet de cette étude, cette non-linéarité est accentuée par la présence de plusieurs barrages à vocation agro-pastorale situés dans la partie nord de la zone d'étude et qui utilisent les eaux de ce fleuve. Ce mémoire de thèse traite donc de la modélisation des débits mensuels du Bandama Blanc, aux stations de Bada, Marabadiassa, Tortiya et Bou, à l'aide des réseaux de neurones, déjà éprouvés dans ce contexte de relation non-linéaire. Elle projette de fournir des outils plus robustes aux hydrologues africains pour la simulation et la prévision des débits des rivières jaugées. Pour atteindre cet objectif, deux Perceptrons Multicouches entraînés avec l'algorithme de la rétropropagation de l'erreur ont été construits. Le premier modèle a été utilisé seulement en simulation et le second en simulation et en prévision. Le modèle conceptuel GR2M, a été utilisé pour valider les résultats obtenus avec les réseaux de neurones. Pour cette étude, une importante base de données climatiques (pluie et température et hydrométriques (débits mensuels a été utilisée. Les résultats obtenus sont forts satisfaisants et nettement supérieurs à ceux obtenus avec le modèle conceptuel global GR2M. En effet, les réseaux de neurones parviennent à expliquer plus de 70 % de la variation des débits, avec des coefficients de corrélation de Pearson qui excèdent 0,80. Cependant ces modèles arrivent difficilement à simuler et à faire la prévision des débits extrêmes (étiages et crues, à cause probablement du nombre réduit de données à notre disposition et de la séparation des bases de calage et de validation.The rainfall-runoff relationship is the subject of many studies because of its importance in the implementation of many development projects. The scientific community, in order to cope with water problems such as floods and droughts, used different models. But these models are usually faced with the non-linearity of the rainfall-runoff relationship. In the case of the Bandama Blanc purpose of this study, this non-linearity is enhanced by the presence of several agro-pastoral dams located in the northern part of the study area and using the waters of this river. This thesis therefore deals with the modeling of flows of Bandama Blanc hydrometric stations (Bada Marabadiassa, Tortiya and Bou using neural networks already experienced in the context of non-linear relationship. It plans to provide more robust tools to African hydrologist in the simulation and forecasting of river flows. To achieve this goal, two Multilayer Perceptrons trained with the backpropagation algorithm of error have been built. The first model was used only in simulation and the second in simulation and prediction. The conceptual model GR2M was used to validate the results obtained with neural networks. An extensive database climate (rainfall and temperature and river monthly flow was used in this study. The results obtained are very satisfactory and well above those obtained with the overall conceptual model GR2M. Indeed, neural networks are able to explain more than 70% of the variation in rates, with Pearson correlation coefficients exceeding 0.80. However, these models have difficulty to simulate and predict extremes flow probably because of the reduced number of data at our disposal and separation of bases calibration and validation.

    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 and alteration of glutathione status.

    In the northeastern Ivory-Coast, volcanic formations having different geochemical features are located in the Haute-Comoe volcano-sedimentary Birimian terrains (Palaeo-Proterozoic). They consist of tholeiites belonging to greenstone belts and showing an oceanic magmatic signature, andesitic calc-alkaline lavas interbedded in the sediments of the Haute-Comoe Basin and related to an active margin-type magmatic genesis, and rhyodacitic intrusions spatially and geochemically linked to granitoid plutons. The magmatic characterization, in terms of geotectonic contexts leads to the following scheme: formation of the greenstone belts in a juvenile oceanic context with building of oceanic plateau (2.195 Ga), genesis of granitoid batholites with metamorphose the belts and beget a first continental crust (2.15 Ga), opening of a sedimentary basin in a shear-zone corridor with local production of calc-alkaline volcanism due to heat transfer along a major lithospheric fault (2.15 - 2.10 Ga), shortening of the basin with leucogranite intrusions in the same transcurrent context (2.09 Ga). This geodynamical scheme takes account of the distinction between two major volcano-tectonic phases: a tholeiitic phase with the greenstone belt formation and then, a calc-alkaline phase linked to the structural evolution of the sedimentary basin. This model could be applied to other Ivory-Coast Birimian terrains, but it is necessary to distinguish the volcanics and the sediments belonging to the greenstone belts and those of the basins which were emplaced between the batholiths.

  5. Securitization of Receivables - An Analysis of the Inherent Risks

    Directory of Open Access Journals (Sweden)

    José Roberto Ferreira Savoia

    2009-06-01

    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 cotes 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.

    On the basis of plate tectonic theory and petroleum geology theory,we analyzed the formation and evolution of West Africa coastal basins, studied deepwater exploration data and typical deepwater oil & gas fields, and discussed petroleum geologic characteristics and exploration potential of deepwater areas in West Africa. The evolution of West Africa coastal basins can be divided into pre-rift stage, syn-rift stage, and post-rift stage. Controlled by formation and evolution of the hasins, most of deepwater fields developed in post-rift stage and oil fields are predominant. Oil and gas found in West Africa deepwater settings are generated from Lower Cretaceous (syn-rift stage) lacustrine source rocks, Upper Cretaceous and Tertiary (post-rift stage) marine source rocks. The most important deepwater reservoirs are turbidite channel sandstone. The main types of deepwater traps are combined stratigraphic-structural traps, followed by structural traps and stratigraphic traps. Deepwater exploration potential is best in Lower Congo basin and Niger Delta, and is good in Cote D'ivoire basin, Benin basin and Senegal basin. Douala basin and Rio Muni basin have fair deepwater exploration potential, whereas, deepwater exploration may be highly risky in Kwanza basin.%以板块构造理论和石油地质学理论为基础,通过分析西非海岸盆地的形成和演化,结合西非深水区油气勘探现状和深水油气藏研究结果,总结了西非深水区油气地质特征,并探讨了深水区油气勘探前景.西非海岸盆地的形成演化可以分为前裂谷、裂谷和后裂谷3个阶段.受盆地形成演化的控制,西非海岸盆地烃源岩主要包括裂谷阶段下白垩统湖相烃源岩、后裂谷阶段上白垩统海相烃源岩和古近系一新近系海相烃源岩3套;深水区储层以后裂谷阶段上白垩统和古近系一新近系深水浊积砂岩为主;主要圈闭类型为构造-地层或构造-岩性圈闭,其次为构造圈闭和地

    The COmorbidity TEst (COTE) is a Chronic Obstructive Pulmonary Disease (COPD)-specific co-morbidity score created to predict mortality. Before its wide application at the University of New Mexico we intended to validate it. The study was conducted at the University of New Mexico Hospital (UNMH) in Albuquerque, NM, USA, a tertiary academic hospital. Consecutive patients with the clinical diagnosis of COPD were identified using the hospital's medical records system and included if they were older than 40 years, had smoked at least 20 pack-years and their post bronchodilator forced expiratory volume in the first second/forced vital capacity (FEV1/FVC) was <0.7 without an alternative diagnosis. The data collected included demographics, co-morbidities as described in the COTE, COPD-specific therapies, spirometry results and mortality. Of 317 patients 51.4% were male, average age was 65.6 ± 9.6 years and the mean post-bronchodilator FEV1 percent predicted (FEV1%) was 52.9 ± 16.9%. 31 (9.8%) patients were on triple long-acting bronchodilator inhaler therapy, 88 (27.8%) on two long-acting bronchodilators and 163 (51.4%) on at least one long-acting bronchodilator. The median follow-up was 3.5 years (IQR = 1.9-6.9). Fifty four patients died by the end of the follow-up period and their median COTE of 4 (IQR = 1-8) was significantly higher than for the survivors with COTE = 1 (IQR = 0-6; p = 0.002). In univariable analyses COTE was positively associated while FEV1%, body mass index (BMI) and gender were negatively associated with all-cause mortality. In multivariable analysis BMI, FEV1% and COTE remained independent predictors for mortality. The COTE is an independent predictor of mortality for COPD patients at UNMH.

    The litho-structural features of Palaeo-proterozoic terrains of northeastern Ivory-Coast, greenstones belts and then sedimentary (basin Birimian), are similar to those of Archaean terrains. Their early deformation is only voluminal deformation due to granitoid intrusions, mainly between 2.2 and 2.16 Ga. The shortening deformation (main deformation) is expressed by right folds and transcurrent shear zones ca 2.1 Ga. Neither thrust deformation nor high pressure metamorphic assemblages are known. This pattern of flexible and hot crust, at least between 2.2 and 2.16 Ga, is pole apart to a collisional pattern, proposed for West African Craton by some authors. The Archaean/Palaeo-proterozoic boundary would not represent a drastic change of the geodynamic evolution of the crust. (authors). 60 refs., 5 figs., 6 photos.

Des études de champ ont été conduites de 1995 à 1996 dans la savane nord-guinéenne du Nigeria afin de déterminer les réponses de 22 génotypes de soja à une infestation par Alectra. Des différences significatives ont été observées entre les génotypes de soja quant au nombre de pousses d'Alectra émergées à 9 et 10 semaines après semis et au nombre de jours à la première émergence d'Alectra. L'émergence d'Alectra a été retardée sur les génotypes de soya à maturité précoce (54 jours après semi, tandis que pour les variétés à maturité plus tardive, Alectra a émergé déjà à partir de 50 jours après semis. Seize génotypes ont montré une faible infestation, parfois inexistante, d'Alectra tandis que les six autres étaient fortement parasités. Les génotypes de soja fortement infestés par les pousses d'Alectra ont enregistré des rendements inférieurs aux autres variétés. Cependant, SAMSOY2 et TGX1485-ID qui ont supporté une infestation relativement forte d'Alectra ont montré des rendements proches des génotypes peu ou non infestés d'Alectra. Nos résultats suggèrent trois mécanismes possibles de résistance au parasitisme d'Alectra parmi les génotypes de soja. Les seize génotypes peu ou non infestés de pousses Alectra pourraient avoir produit une quantité insignifiante d'exsudats de racines nécessaires pour la stimulation de la germination des graines d'Alectra. SAMSOY et TGX1485-1D qui ont donné un rendement élevé malgré l'importante infestation d'Alectra montreraient ainsi une tolérance au parasite.

This study aims to identify trends in the rainfall-runoff relationship by using a monthly conceptual model. The methodology has consisted on the one hand in highlighting the existence of interannual climate and hydrological variability by using the method of segmentation of Hubert, and on the other hand, in applying the crossed simulations method by using the GR2M model, over several 7-year sub-periods. The results of the application of the method of segmentation of Hubert have demonstrated the presence of a hydroclimatic variability in the N'zi watershed. The modifications of the climate and physical conditions of the flow resulted in a modification of the hydrological response of the watershed translated by a non-stationarity in the rainfall-runoff relation.

    Full Text Available The Fishing of Mugilidae in Grand-lahou Lagoon (Ivory Coast: Analysis of Fishing Organisation, Captures and Fishing Effort. Sixteen sites, around the lagoon, have been investigated from April 2009 to March 2011. At the pass, fishing with sparrow hawks is mainly done by Ghanaians. On the other sites of lagoon, indigenous fishers are dominant and use gill-nets. Ocean area, with more than 50% of activities and 60% of captures, is the place where the highest production is realized. The site around the pass provides 25% of activities and 20% of capture. At the pass and in the continental area of the lagoon, captures remain inferior to 10%. There, the peak of captures is registered in July and the lowest ones from February to April. On the others sites of the lagoon, two peaks can be observed in December, May and July. From the end of July to the end September, captures from ocean and the pass remain very low. During this period, fishing is interrupted on the others sites for Mugilidae are rare and water is desalinated because of continental waterways pouring out in the lagoon. Fishing efforts peaks don't always coincide with capture peaks even if during high captures period, fishing effort values are very high.

    Full Text Available Background. This study evaluated the effectiveness of managing posterior blepharitis (PB using a novel Posterior Blepharitis Management Protocol (PBMP. Design. Prospective, consecutive case series with 100% followup to one month. Participants. 27 patients (54 eyes with PB from an Ophthalmology practice in Sydney, Australia. Methods. Each patient’s PB was assessed by grading the nature and expressibility of the central lower lid tarsal gland secretions on Compression Of The Eyelid (COTE. Patients were then instructed in detail to undertake daily PB management sessions at home using our modified PBMP. Main Outcome Measures. On a subjective scale, patients compared their symptoms at one month with baseline. COTE scores were reevaluated to assess the objective effectiveness of each individual’s PBMP. COTE scoring was described as grades 1 (clear oil, 2 (pus, liquid, 3 (toothpaste-like secretions, and 4 (complete tarsal gland obstruction. Results. Patients reported a mean 77.8% ± 13.5% subjective improvement in symptoms.

  14. Seismic Anisotropy from the Core-Mantle Boundary to the Surface

    Science.gov (United States)

    Lynner, Colton Lee

    splitting measurements of SK(K)S phases that sample the lowermost mantle beneath Africa. In Chapter 4, I present measurements of SKS and SKKS splitting at station DBIC in the Cote D'Ivoire. The splitting pattern is dominated by null measurements over a wide range of backazimuths, with non-null measurements found over a very limited backazimuthal range. Splitting at DBIC has previously been interpreted in terms of upper mantle anisotropy, but we argue that an apparently isotropic upper mantle can best explain this splitting pattern with a contribution from anisotropy in the lowermost mantle. In Chapter 5, I present SKS and SKKS splitting measurements that likely reflects a contribution from lowermost mantle anisotropy beneath Africa. The vast majority of discrepant pairs sample the boundary of the African large low shear-wave velocity province (LLSVP), which dominates the lower mantle structure beneath this region. In general, I observe little or no splitting of phases that have passed through the LLSVP itself and significant splitting for phases that have sampled the boundary of the LLSVP. I infer that the D" region just outside the LLSVP boundary is strongly deformed, while its interior remains undeformed (or weakly deformed). In Chapter 6, I examine the anisotropic structure of the mid-mantle (transition zone and uppermost lower mantle) beneath the Japan, Izu-Bonin, and South America subduction systems. In each region, I observe consistent splitting with delay times as large as 1 sec, indicating the presence of anisotropy at mid-mantle depths. Clear splitting of phases originating from depths as great as ~600km argues for a contribution from anisotropy in the uppermost lower mantle as well as the transition zone. The goal of Chapter 7 is to evaluate predicted sub-slab splitting from 3D geodynamic models using a variety of different anisotropic fabric types. This builds on Chapter 3; in which only very simplified sub-slab dynamics and approximated LPO fabrics were used

    We investigate the electronic structures and stability for Ni/Bi 2Te3, NiTe/Bi2Te3, Co/Bi 2Te3 and CoTe2/Bi2Te3 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 Bi2Te3. The interface formation energy for Co/Bi2Te3 interfaces is much lower than that of Ni/Bi2Te3 interfaces. Furthermore, we found that NiTe on Bi2Te3 is more stable than Ni, while the formation energies for Co and CoTe2 on Bi2Te3 are comparable. © 2010 IOP Publishing Ltd.

    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.

  11. Threshold cointegration and causality relationship between energy use and growth in seven African countries

    2010-11-15

    The paper investigates the long-run and the causality relationship between energy consumption and economic growth for seven Sub-Saharan African countries during the period 1970-2007. Using the Gregory and Hansen testing approach to threshold cointegration, we find that energy consumption is cointegrated with economic growth in Cameroon, Cote d'Ivoire, Ghana, Nigeria and South Africa. Moreover, this test suggests that economic growth has a significant positive long-run impact on energy consumption in these countries before 1988 and this effect becomes negative after 1988 in Ghana and South Africa. Furthermore, causality tests suggest bidirectional causality between energy consumption and real GDP in Cote d'Ivoire and unidirectional causality running from real GDP to energy usage in the case of Congo and Ghana.

  15. Introduction: Victorian Theatricalities

    Directory of Open Access Journals (Sweden)

    Michael Dobson

    2009-04-01

    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.

    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.
