Determinants economiques et impact social du secteur maraicher dans la commune de Boundiali

Le maraîchage est l’une des principales sources de revenu monétaire et d’autosubsistance alimentaire des populations Nord de la Côte d’Ivoire. L’objectif de cette étude est de déterminer les caractéristiques sociologiques des producteurs, d’évaluer les déterminants de la productivité et de la rentabilité économique et enfin, d’identifier les changements sociaux induits par cette activité. Pour y parvenir, une enquête a été menée auprès de 50 maraîchers choisis sur la base d’un échantillonnage aléatoiredans la commune de Boundiali. La statistique descriptive et analytique, l’approche budgétaire et la méthode d’analyse sociale ont permis d’analyser les données. Des résultats, l’on conclut que le secteur du maraîchage est détenu en majorité par des femmes (68%). Les maraîchers sont en général membres des groupements ou associations de paysans (84 %), illettrés (91 % chez les femmes et 63 % chez les hommes) et financent leur activité sur fonds propres (90 %). Cette activité emploiemajoritairement la main d’oeuvre familiale (90 %). Ce qui justifie  l’étroitesse des superficies exploitées (entre 175 et 300 m²) et de la faiblesse des revenus (385 420 FCFA / an). Enfin, le revenu issu du maraîchage améliore le taux de satisfaction alimentaire journalier de la famille du maraîcher (67%), le niveau de scolarisation (68,75 %) et l’accès aux soins de santé (64 %). L’activité maraîchère est par conséquent une source d’autonomisation et d’amélioration des conditions de vie des maraîchers.Mots-clés : maraîchage - rentabilité - déterminants - impact - Boundiali English Title:  Economic determinants and social impact of market gardening in the district of Boundiali Market gardening remains one of the main sources of monetary income and food self-sufficiency for the northern populations of Cote d’Ivoire. The objective of this study is to determine the sociological characteristics of producers, to assess the determinants of productivity and economic  profitability and finally to identify the social changes induced by this activity. To achieve this, a survey was conducted among 50 market gardeners selected on the basis of random sampling in the commune of Boundiali.The descriptive and analytical statistics, the budget approach and the social analysis method made it possible to analyse the data. From the results, it is concluded that the market gardening sector is mainly owned by women (68%). Market gardeners are generally members of farmers’ groups orassociations (84%), illiterate (91% of women and 63% of men) and finance their activity with their own funds (90%). This activity mainly employs family workers (90%). This justify the small size of the areas cultivated (between 175 and 300 m2) and the low income (385 420 CFA francs per year). Finally, the income from market gardening improves the daily food satisfaction rate of the market gardener’s family (67%), the level of schooling (68,75%) and access to health care 64%). Market gardening is therefore a source of empowerment and improvement of the living conditions of market gardeners.Keywords: market gardening - profitability - determinants - impact - Boundial

Management of Vesicouterine fistulae during fistulae surgical caravan in Cote d'Ivoire

Background: The urogenital fistula (UGF) which designate a solution of continuity between the urinary and genital tracts in women, are divided into several entities of variable gravity. The objective of this study was to describe the epidemiological, clinical and therapeutic characteristics of patients treated for vesicouterine fistula during ‘fistulas surgical caravans’.Methods: This was a prospective and descriptive study on a cohort of 34 patients treated for Vesico-uterine fistulae during ‘‘fistulas surgical caravans '' from 1st January 2012 to 31st December 2016.Results: Vesico uterine fistulae represented 2.1% of all urogenital fistulae treated. At the time of occurrence of fistulas, the average age of the patients stay was 33.3 years, and the majority was not educated (88.2%), lived in rural areas without occupations (73.5%). All the fistulae were secondary to childbirth, the majority of which took place on a scarred uterus (67.6%). And this childbirth responsible for the fistula was done by caesarean section in 97.7% of cases. Then the average duration of the fistula before management was 6 years. Finally, all the patients were operated by the same surgical technique, made by abdominal extra peritoneal transvesical way. The cure rate after this surgical technique was 97.1% (33 patients). The only case of failure required a second operation by another technique which permitted the healing of the patient.Conclusions: The vesicouterine fistulae were rare and the satisfactory results of their management invite us to sustain these surgical caravans and ensure their widespread

Evolutionary profile of patients with hemoglobin SC disease regularly followed in Côte d'Ivoire

Background: West Africa is recognized as the elective focus of hemoglobin C. The S and C combination in the same patient gives a major sickle cell syndrome. In our country, very few series dealing with the evolutionary features of this SC form have been published contrary to the homozygous SS form. The aim of this study was to describe the evolutionary profile of double heterozygous SC sickle cell patients.Methods: This was a retrospective and prospective study with descriptive and analytical purpose of 174 SC sickle cell patients.Results: The median age was 26 years with extremes of 6 years and 57 years. 96% of patients had less than 4 vaso-occlusive seizures per year. The evolutionary complications were mainly ischemic (56.30%) and infectious (39.10%). Among ischemic complications, sickle cell retinopathies and aseptic osteonecrosis are the most common with 59.20% and 31.63% respectively. Infectious complications were dominated by ENT (36.76%) and osteoarticular (35.29%) infections. Only age had an influence on the occurrence of ischemic complications (p = 0.0001). The probability of survival at 5 years was 99.38% and that at 20 years was 91.57%. The overall survival was not influenced by evolutionary complications.Conclusions: Infectious and ischemic evolutionary complications show the importance of vaccination and an early screening program

Models of support for disclosure of HIV status to HIV-infected children and adolescents in resource-limited settings

Introduction: Disclosure of HIV status to HIV-infected children and adolescents is a major care challenge. We describe current site characteristics related to disclosure of HIV status in resource-limited paediatric HIV care settings within the International Epidemiology Databases to Evaluate AIDS (IeDEA) consortium. Methods: An online site assessment survey was conducted across the paediatric HIV care sites within six global regions of IeDEA. A standardized questionnaire was administered to the sites through the REDCap platform. Results: From June 2014 to March 2015, all 180 sites of the IeDEA consortium in 31 countries completed the online survey: 57% were urban, 43% were health centres and 86% were integrated clinics (serving both adults and children). Almost all the sites (98%) reported offering disclosure counselling services. Disclosure counselling was most often provided by counsellors (87% of sites), but also by nurses (77%), physicians (74%), social workers (68%), or other clinicians (65%). It was offered to both caregivers and children in 92% of 177 sites with disclosure counselling. Disclosure resources and procedures varied across geographical regions. Most sites in each region reported performing staff members' training on disclosure (72% to 96% of sites per region), routinely collecting HIV disclosure status (50% to 91%) and involving caregivers in the disclosure process (71% to 100%). A disclosure protocol was available in 14% to 71% of sites. Among the 143 sites (79%) routinely collecting disclosure status process, the main collection method was by asking the caregiver or child (85%) about the child's knowledge of his/her HIV status. Frequency of disclosure status assessment was every three months in 63% of the sites, and 71% stored disclosure status data electronically. Conclusion: The majority of the sites reported offering disclosure counselling services, but educational and social support resources and capacities for data collection varied across regions. Paediatric HIV care sites worldwide still need specific staff members' training on disclosure, development and implementation of guidelines for HIV disclosure, and standardized data collection on this key issue to ensure the long-term health and wellbeing of HIV-infected youth

Revisiting the Immune Trypanolysis Test to Optimise Epidemiological Surveillance and Control of Sleeping Sickness in West Africa

Human African trypanosomiasis (HAT) due to Trypanosoma brucei (T.b.) gambiense is usually diagnosed using two sequential steps: first the card agglutination test for trypanosomiasis (CATT) used for serological screening, followed by parasitological methods to confirm the disease. Currently, CATT will continue to be used as a test for mass screening because of its simplicity and high sensitivity; however, its performance as a tool of surveillance in areas where prevalence is low is poor because of its limited specificity. Hence in the context of HAT elimination, there is a crucial need for a better marker of contact with T.b. gambiense in humans. We evaluated here an existing highly specific serological tool, the trypanolysis test (TL). We evaluated TL in active, latent and historical HAT foci in Guinea, Côte d'Ivoire and Burkina Faso. We found that TL was a marker for exposure to T.b. gambiense. We propose that TL should be used as a surveillance tool to monitor HAT elimination

Parasite

Parasites and infectious diseases are well-known threats to primate populations. The main objective of this study was to provide baseline data on fecal parasites in the cercopithecid monkeys inhabiting Côte d'Ivoire's Taï National Park. Seven of eight cercopithecid species present in the park were sampled: Cercopithecus diana, Cercopithecus campbelli, Cercopithecus petaurista, Procolobus badius, Procolobus verus, Colobus polykomos, and Cercocebus atys. We collected 3142 monkey stool samples between November 2009 and December 2010. Stool samples were processed by direct wet mount examination, formalin-ethyl acetate concentration, and MIF (merthiolate, iodine, formalin) concentration methods. Slides were examined under microscope and parasite identification was based on the morphology of cysts, eggs, and adult worms. A total of 23 species of parasites was recovered including 9 protozoa (Entamoeba coli, Entamoeba histolytica/dispar, Entamoeba hartmanni, Endolimax nana, Iodamoeba butschlii, Chilomastix mesnili, Giardia sp., Balantidium coli, and Blastocystis sp.), 13 nematodes (Oesophagostomum sp., Ancylostoma sp., Anatrichosoma sp., Capillariidae Gen. sp. 1, Capillariidae Gen. sp. 2, Chitwoodspirura sp., Subulura sp., spirurids [cf Protospirura muricola], Ternidens sp., Strongyloides sp., Trichostrongylus sp., and Trichuris sp.), and 1 trematode (Dicrocoelium sp.). Diversity indices and parasite richness were high for all monkey taxa, but C. diana, C. petaurista, C. atys, and C. campbelli exhibited a greater diversity of parasite species and a more equitable distribution. The parasitological data reported are the first available for these cercopithecid species within Taï National Park. Les maladies parasitaires et infectieuses sont des menaces très connues pour les populations de primates. L’objectif principal de cette étude était de fournir des données de base sur les parasites intestinaux des primates non-humains du Parc National de Taï en Côte d’Ivoire. Sept des huit espèces de cercopithécidés vivant dans le parc ont été échantillonnées : Cercopithecus diana, Cercopithecus campbelli, Cercopithecus petaurista, Procolobus badius, Procolobus verus, Colobus polykomos and Cercocebus atys. Nous avons collecté 3142 échantillons de selles de singes de novembre 2009 à décembre 2010. Les échantillons de selles ont été traités par la technique d’examen direct, les méthodes de concentration formol-éthyl acétate et MIF (merthiolate, iode, formol). Les lames ont été examinées au microscope et l’identification des parasites a été basée sur la morphologie des kystes, des œufs et des vers adultes. Au total, 23 espèces de parasites ont été trouvées, dont 9 protozoaires (Entamoeba coli, Entamoeba histolytica/dispar, Entamoeba hartmanni, Endolimax nana, Iodamoeba butschlii, Chilomastix mesnili, Giardia sp., Balantidium coli et Blastocystis sp.), 13 nématodes (Oesophagostomum sp., Ancylostoma sp., Anatrichosoma sp., Capillariidae Gen. sp. 1, Capillariidae Gen. sp. 2, Chitwoodspirura sp., Subulura sp., Spiruridae [cf. Protospirura muricola], Ternidens sp., Strongyloides sp., Trichostrongylus sp. et Trichuris sp.), et un trématode (Dicrocoelium sp.). L’indice de diversité et la richesse parasitaire étaient élevés pour tous les taxa de singes, mais C. diana, C. petaurista, C. atys and C. campbelli ont enregistré une plus grande diversité et une distribution plus équitable des espèces de parasites. Les données parasitologiques que nous rapportons sont les premières disponibles pour ces espèces de singes du Parc National de Taï

12-month mortality and loss-to-program in antiretroviral-treated children: The IeDEA pediatric West African Database to evaluate AIDS (pWADA), 2000-2008

<p>Abstract</p> <p>Background</p> <p>The IeDEA West Africa Pediatric Working Group (pWADA) was established in January 2007 to study the care and treatment of HIV-infected children in this region. We describe here the characteristics at antiretroviral treatment (ART) initiation and study the 12-month mortality and loss-to-program of HIV-infected children followed in ART programs in West Africa.</p> <p>Methods</p> <p>Standardized data from HIV-infected children followed-up in ART programs were included. Nine clinical centers from six countries contributed to the dataset (Benin, Côte d'Ivoire, Gambia, Ghana, Mali and Senegal). Inclusion criteria were the followings: age 0-15 years and initiated triple antiretroviral drug regimens. Baseline time was the date of ART initiation. WHO criteria was used to define severe immunosuppression based on CD4 count by age or CD4 percent < 15%. We estimated the 12-month Kaplan-Meier probabilities of mortality and loss-to-program (death or loss to follow-up > 6 months) after ART initiation and factors associated with these two outcomes.</p> <p>Results</p> <p>Between June 2000 and December 2007, 2170 children were included. Characteristics at ART initiation were the following: median age of 5 years (Interquartile range (IQR: 2-9) and median CD4 percentage of 13% (IQR: 7-19). The most frequent drug regimen consisted of two nucleoside reverse transcriptase inhibitors and one non-nucleoside reverse transcriptase inhibitors (62%). During the first 12 months, 169 (7.8%) children died and 461(21.2%) were lost-to-program. Overall, in HIV-infected children on ART, the 12-month probability of death was 8.3% (95% Confidence Interval (CI): 7.2-9.6%), and of loss-to-program was 23.1% (95% CI: 21.3-25.0%). Both mortality and loss-to program were associated with advanced clinical stage, CD4 percentage < 15% at ART initiation and year (> 2005) of ART initiation.</p> <p>Conclusion</p> <p>Innovative and sustainable approaches are needed to better document causes of death and increase retention in HIV pediatric clinics in West Africa.</p

Early infant HIV-1 diagnosis programs in resource-limited settings: opportunities for improved outcomes and more cost-effective interventions

Early infant diagnosis (EID) of HIV-1 infection confers substantial benefits to HIV-infected and HIV-uninfected infants, to their families, and to programs providing prevention of mother-to-child transmission (PMTCT) services, but has been challenging to implement in resource-limited settings. In order to correctly inform parents/caregivers of infant infection status and link HIV-infected infants to care and treatment, a 'cascade' of events must successfully occur. A frequently cited barrier to expansion of EID programs is the cost of the required laboratory assays. However, substantial implementation barriers, as well as personnel and infrastructure requirements, exist at each step in the cascade. In this update, we review challenges to uptake at each step in the EID cascade, highlighting that even with the highest reported levels of uptake, nearly half of HIV-infected infants may not complete the cascade successfully. We next synthesize the available literature about the costs and cost effectiveness of EID programs; identify areas for future research; and place these findings within the context of the benefits and challenges to EID implementation in resource-limited settings

HIV Status Disclosure and Retention in Care in HIV-Infected Adolescents on Antiretroviral Therapy (ART) in West Africa

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.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.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).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
