Exposure of children to fine particles (PM2.5 and PM10) in schools in the health districts of Yopougon, Abidjan

Background: In Africa, the school environment is becoming a growing concern, as concentrations of fine particles inside classrooms are very high. We decided to estimate the level of exposure to PM2.5 and PM10 of schoolchildren in the health districts of Yopougon in Abidjan. Methods: This was an analytical cross-sectional study of pupils aged 8 to 14 years in the health districts of Yopougon. Our study was conducted from 24 November 2020 to 18 January 2021. The pupils were selected by two-stage random sampling. A real-time fine-particle measurement instrument, the DYLOS 1700, and the ISAAC questionnaire were used to collect the parameters studied. Results: We surveyed 881 pupils from 08 schools. The sex ratio (M/F) of the pupils was 0.9 and the mean age was 12 years. Measurements of PM2.5 and PM10 levels in the classrooms were 30 times higher than WHO standards and ranged from 200 to 1000 µg/m3 and 1000 to 3000 µg/m3 respectively. There was a significant link between the presence of pollution sites near schools and the increase in PM2.5 and PM10 levels in classrooms. Clinical manifestations suggestive of asthma in pupils were significantly associated with high levels of PM2.5 and PM10. Conclusions: Pupils in Yopougon’s schools are exposed to high level of fine particle pollution that exceed WHO standards. Respecting and applying pollution reduction measures will help to create a school environment that is favourable to the respiratory health of pupils.

Etude du paiement électronique des agents de santé: cas de la campagne de vaccination contre la rougeole et la rubéole en Côte d'Ivoire / NA

La motivation des agents de santé à travers le paiement à temps et complet constitue l'un des éléments clés pour atteindre de bonne couverture vaccinale. Notre objectif était de décrire le paiement électronique utilisé lors de la campagne rubéole-rougeole et d'apprécier la satisfaction du personnel de santé. Nous avons réalisé une étude transversale à visée analytique qui s'est déroulée en Côte d'Ivoire du 15 janvier au 18 février 2019. La population d'étude était constituée des acteurs impliqués à la fois dans la campagne de vaccination contre la rougeole- rubéole en 2018 et dans le paiement électronique. Une recherche documentaire et des entretiens structurés ont permis le recueil des données. Les données ont été analysées à partir du logiciel R studio© version 2021. Le système assurant le paiement électronique se composait des autorités sanitaires, d'un opérateur privé de téléphonie mobile, d'un partenaire technique et financier et des agents de santé bénéficiaires. Un système de critères d'identification, des listes de validation et de vérification à plusieurs niveaux de la pyramide sanitaire a été mis en place. Un peu moins de trois quarts des acteurs du niveau primaire ont été satisfaits par ce mode de paiement. Le paiement électronique constitue un procédé pour améliorer le paiement des agents de santé durant les campagnes de vaccination. Des leçons d'un tel système de paiement devraient être tirées pour un déploiement à grande échelle.

Motivating healthcare workers through timely and complete payment is one of the key elements to achieve high vaccination coverage. Our objective was to describe the use of electronic payment during the measles-rubella campaign and assess the satisfaction of healthcare personnel. We conducted a cross-sectional analytical study in Côte d'Ivoire from January 15 to February 18, 2019. The study population consisted of individuals involved in both the measles-rubella vaccination campaign in 2018 and electronic payment. Data collection was done through documentary research and structured interviews. The data were analyzed using R Studio© software version 2021. The electronic payment system involved health authorities, a private mobile network operator, a technical and financial partner, and the beneficiary healthcare workers. A system of criteria for identifying lists, validation, and multilevel verification within the healthcare pyramid was established. Just under three-quarters of primarylevel actors were satisfied with this payment method. Electronic payment presents an opportunity to improve healthcare worker payment during vaccination campaigns. Lessons from such a payment system should be drawn for large-scale deployment.

Use of Selected Chemical and Biological Insecticides to Control Lepidopteran Pests of Maize Fields in Central Côte d'Ivoire

Control of lepidopteran larvae, the main pests in maize fields, has become necessary since the appearance and spread of Spodoptera frugiperda. The study was carried out at the Institut National Polytechnique Houphouët-Boigny in Yamoussoukro (Central Côte d’Ivoire). The study aimed to determine the effectiveness of three chemical - Viper 46 EC (Acetamiprid 16 g/l and Indoxacarb 30 g/l), K-Optimal 35 EC (Lambdacyhalothrin 15 g/l and Acetamiprid 20 g/l) and Ampligo 150 ZC (Chlorantanlipol 100 g/l and Lambdacyhalothrin 50 g/l) - and one biological insecticide Bio-Elit (Azadirachtin, Salanin, Nimbin and Melandriol) on lepidopteran larvae in maize fields using a randomized complete block design with five treatments and three repetitions. Data on insect identification, plant infestation, damage, and yield were collected. Insects’ identification was based on morphology using identification keys. Plant damage was assessed by visually estimating the plant health status (unattacked and attacked plants). Grain dry weight was used to estimate field yield. The encountered maize field insects belonged to 10 orders: Heteroptera, Hymenoptera, Homoptera, Coleoptera, Diptera, Dictyoptera, Odonata, Orthoptera, Dermaptera, and Lepidoptera. Five lepidopteran pest larvae have been recorded. Three of them were classified as minor pests (Eldana saccharina, Ostrinia nubilalis, and Helicoverpa zea), one as important (Sesamia calamistis), and one as a major pest (Spodoptera frugiperda). On untreated plots, more than 76% of plants were moderately to heavily attacked. However, on treated plots, plants showed isolated to moderate attacks. Insecticide sprayings controlled pest populations, reduced damage, and increased yield. The yields obtained on untreated plots (2.26±0.21 t/ha) were lower than those on treated plots (3.29±0.11 to 3.60±0.09 t/ha). The yield increase rate ranged from 45.74 to 59.63%. The best control was recorded with Ampligo (59.63%) and Bio-Elit (50.83%) compared to Viper (49.41%) and K-Optimal (45.74%). Therefore, the alternating use of synthetic or biological insecticides, which are not very toxic for humans and the environment but are effective on insect pests, increases the effectiveness of the control and provides a positive response to the problem of pest resistance while protecting the environment.

Occurrence, Ecological and Health Risks of Organic Pollution of the Waters from a Tropical Lake System

The monitoring of the organic pollution level and the ecological and health risks of the waters from the Déganobo lake system were the subject of this study. In its implementation, the water samples were collected monthly in this aquatic ecosystem over a year (from August 2021 to July 2022). The organic pollution level of these waters was assessed using their Chemical Oxygen Demand, determined in accordance with NF T 90-101 standard. The ecological and health risks were assessed based on the SEQ-Eau V2 water quality guidelines. Their COD seasonal mean values were between 220,000±51,872 and 361,333±48,273 mg/L O2. So, their organic pollution was relatively very significant, with the corollary of the zero of its seasonal transparencies and of its seasonal dissolved oxygen contents. The seasonal dynamics of organic matter in these waters was essentially linked to the hydroclimate (rainfall and ambient temperature) on the watershed of this lake system. The low meteorite waters inputs in dry seasons favoured the increase of their COD by the important punctual wastes inputs of various origins (domestic, agricultural, industrial, hospital, etc.); in opposite of the important meteorite waters inputs in rainy seasons causing their renewal. The consequences of their important COD values are severe ecological and health risks, as highlighted by SEQ-Eau V2 water quality guidelines. So, this lake system is under the strong anthropogenic pressures. This study could serve as complementary information on its pollution level and contribute to decision-making for its rehabilitation, its protection within the framework of its sustainable development.

Climate and Agriculture in Côte D'ivoire: Perception and Quantification of the Impact of Climate Change on Cocoa Production by 2050

Cocoa contributes 7.5% of Côte d'Ivoire's Gross Domestic Product (GDP) and is an important cash crop for the rural population in the country's forest areas. Cocoa, like the crops of West Africa, is deeply affected by the consequences of climate change. The objective of this research is to predict the impact of climate change on cocoa production in the main producing regions of Côte d'Ivoire and to analyze farmers' perceptions of climate change. The soil data were those of the World Harmonized Database version 1.2 of the FAO and allowed the spatio-temporal analysis of the useful reserve of water in the soil. The socio-economic data used integrated in the production forecasting model were taken from the report of the Census of Farmers and Farms 2015/2016. The temperature and precipitation series over the period 1981-2016 served as a climatic reference. The RCP 4.5 and RCP 8.5 scenarios were used for climate projections by 2050. The results showed a temperature increase of around +1°C to +1.5°C by 2050 ; and a decrease in rainfall over the entire Ivorian territory. According to the developed model, national cocoa production is expected to fall by around 17% and 23% respectively under the RCP 4.5 and 8.5 scenarios. Moreover, some current cocoa production areas will become unsuitable (Lagunes and Sud-Comoe in Côte d'Ivoire) due to the new pedoclimatic conditions. The results obtained also highlighted a relatively low level of knowledge of cocoa producers regarding the effects of climate on well-being.

Ethnopharmacological Characteristics of Pycnanthus angolensis (Welw.) Warb. (Myristicaceae), a Plant Used in the Traditional Treatment of Viral and Parasitic Diseases

Background: Pycnanthus angolensis (Welw.) Warb. (Myristicaceae) is a medicinal plant used in traditional Ivorian medicine. A recent ethnobotanical survey has discovered Pycnanthus angolensis in the traditional treatment of viral and parasitic diseases. Aim: The present study aims to highlight the distinctive ethnopharmacological characteristics of Pycnanthus angolensis. Methods: The aim was to identify some groups of chemical compounds by thin layer chromatography, to assay some minerals and finally to characterise the specific anatomical and micrographic features of the plant. Results: Terpenes and sterols, saponosides, flavonoids and tannins are the main phytocompounds revealed. Magnesium with 621.3 mg/100 g dry matter is the most abundant mineral. Anatomical sections and plant powder revealed starch grains, calcium oxalate crystals, secretory pockets and tector hairs that are responsible for the formation of various biological substances in the plant. Conclusion: These results add to the data on Pycnanthus angolensis, a taxon much used in traditional Ivorian medicine for the treatment of antiparasitic and antiviral diseases.

Pratique anesthésique pour adénomectomies hypophysaires par voie endonasale à Abidjan, Côte d'Ivoire / Anesthesia for endonasal pituitary adenomectomies in Abidjan, Ivory Coast

L'objectif de l'étude est d'évaluer la pratique anesthésique au cours des adénomectomies hypophysaires par voie endo nasale à Abidjan. Méthode : Il s'agissait d'une étude rétrospective à visée analytique et descriptive, menée entre le 01 janvier 2010 et le 31 décembre 2020 et portant sur les patients admis au bloc opératoire pour une adénomectomie hypophysaire. Les caractéristiques sociodémographiques, cliniques, anesthésiques, évolutives et pronostiques ont été étudiées. Résultats : Nous avons recensé 102 patients. L'âge moyen était de 44,72±12,14 ans. Le sex ratio était de 1. Le délai de diagnostic était d'un an pour 46% (n = 47) des patients. L'hypertension artérielle était l'antécédent le plus retrouvé. Les principaux motifs de consultation étaient les céphalées et les troubles de l'acuité visuelle. Le syndrome d'hypertension intracrânien a été observé chez 67,6% (n= 69) des patients. Tous les patients ont bénéficié d'une consultation pré anesthésique. Cinquante-huit pourcent (n=59) des patients ont été classés ASA I selon la société américaine d'anesthésie. L'anesthésie générale était le seul schéma anesthésique. La durée de l'anesthésie était de plus de trois heures chez 57% (n=58) des patients et le réveil sur table a concerné 88,2% (n=90) des patients. La mortalité était de 3,9%. La durée de l'anesthésie supérieure à 6 heures (p= 0,0012 ; OR= 55,8 [4,88-637,33]) et la perte sanguine supérieure à 1000 ml (p = 0,0228 ; OR=18,6 2,152- 160,747]) ont constitué des facteurs de mauvais pronostic (p<0,05). Conclusion: La réduction de la létalité au cours de l'anesthésie pour adénomes hypophysaires passe par la lutte contre les facteurs de mauvais pronostics

Facteurs de morbidité du syndrome de mal-être post-rachianesthésie / Morbidity factors of post-spinal anesthesia disease syndrome

La pratique de la rachianesthésie est motivée par la qualité de l'analgésie post-opératoire qu'elle procure. Cependant, la rachianesthésie reste comme tout acte médical associée à certains accidents. Méthodes : C'est une étude prospective, descriptive et analytique qui s'est déroulée sur une période d'un (01) mois allant du 07 Mai 2022 au 07 Juin 2022 au CHU d'Angré. Résultats : la rachianesthésie a été réalisée dans 188 des cas, soit un taux de 60% de l'ensemble des interventions. Le sexe ratio était de 0,13 et l'âge moyen était de 33 ± 10 ans. L'antécédent le plus retrouvé était l'HTA. La bupivacaine était le seul anesthésique local utilisé avec comme adjuvant la morphine, le fentanyl ou l'association morphine -fentanyl. Les incidents peropératoires étaient dominés par les troubles hémodynamiques à type d'hypotension artérielle (98,7%) et de bradycardie. Les patients ayant présenté un syndrome de mal être post opératoire représentaient 70,8% de notre effectif. Le Syndrome de Mal Etre post opératoires était dominé par les nausées et vomissements suivis des prurits. Tous les patients ayant présenté un syndrome de mal être post rachianesthésie n'avaient pas bénéficié de prise en charge. La survenue du syndrome de mal être post rachianesthésie était statistiquement associé à la présence de la morphine comme adjuvant (p=0,016). Conclusion : La rachianesthésie est une remarquable technique d'anesthésie. Néanmoins la fréquence des évènements per et post opératoires survenant au décours de cette technique n'est pas négligeable, car ils sont la source d'inconforts notables

Prise en charge médicale du premier épisode de bronchiolite aiguë des nourrissons de moins de 12 mois hospitalisés au CHU de Cocody de 2020 à 2022 / Medical management of first episode of acute bronchiolitis in children less than 12 months old hospitalized at Cocody University Hospital from 2020 to 2022

Introduction. La bronchiolite aiguë du nourrisson est une infection virale des voies aériennes inférieures qui représente un problème majeur de santé publique. L'objectif de cette étude était de décrire la prise en charge médicale du premier épisode de bronchiolite aiguë au CHU de Cocody. Méthodes. Il s'agissait d'une étude rétrospective à visée descriptive qui a consisté à décrire la prise en charge médicale des nourrissons hospitalisés dans le CHU de Cocody du 1er Janvier 2020 au 31 Décembre 2022. Résultats : Sur la période d'étude, 125 nourrissons sont hospitalisés pour bronchiolite aiguë. La tranche d'âge de 4 à 6 mois était majoritaire (49,6%). L'âge moyen des patients est de 4,7 mois avec des extrêmes de 1 à 12 mois (écart-type=1,277 mois). Le sex-ratio était de 1,27. La numération formule anguine (NFS), la C Reactive Protein (CRP) et la radiographie thoracique standard ont été réalisées chez tous les patients. La désobstruction rhino-pharyngée (DRP) a été pratiquée dans 96,0% des cas. Une nébulisation avec du salbutamol a été appliquée à tous les patients. Cette nébulisation a été associée à une antibiothérapie (71,2 %), une corticothérapie (52 %) et à une kinésithérapie respiratoire (48 %). L'évolution a été favorable dans 96 % des cas, malgré une sous-utilisation de la ventilation non-invasive dans notre dans notre contexte. Conclusion : L'analyse de la prise en charge de la bronchiolite aiguë du nourrisson au CHU de Cocody, a revélé des écarts par rapport aux recommandations de la HAS française. Il serait judicieux d'établir un consensus national adapté à notre contexte de travail.

Acute bronchiolitis in infants is a viral infection of the lower airways that represents a major public health problem. The main objective was to describe the management of this condition in the Ivorian pediatric hospital context. Methods. This was a descriptive cross-sectional study, with retrospective data collection. We have described the care of infants aged 1 month to 12 months, hospitalized for bronchiolitis in the Pediatrics department of the CHU of Cocody from January 01, 2020 to December 31, 2022. Results. We collected 125 files. The age group of 4 to 6 months was the majority (49.6%). The average age of the patients was 4.7 months (ecart-type=1,277 months) with extremes of 1 to 12 months. The sex ratio was 1.27. NFS, CRP and AP chest X-ray were performed in all patients. Nasopharyngeal clearance was performed in 96.0% of cases. The infants were all nebulized with salbutamol. Among them, 52% received a corticosteroid, 71.2% antibiotic therapy and in 48% of cases respiratory physiotherapy was performed. The evolution was favorable in 96% of cases. Conclusion : The analysis of the management of acute bronchiolitis in infants at the Cocody University Hospital reveals deviations from the recommendations of the French HAS. It would be wise to establish a national consensus adapted to our work context.

Prévalence et facteurs associés au syndrome d'épuisement professionnel chez le personnel de santé du service de pédiatrie du Centre Hospitalier Universitaire de Bouaké (Côte d'Ivoire) / Prevalence and factors associated with burnout syndrome among health personnel in the paediatric department of the university hospital of Bouaké (Côte d'Ivoire)

Contexte et objectif.: Le syndrome d'épuisement professionnel (SEP) est une pathologie particulièrement préoccupante en milieu hospitalier avec un impact négatif sur la qualité des soins. L'objectif de l'étude était de connaitre la prévalence et les principaux facteurs associés au SEP chez le personnel de santé en pédiatrie au CHU de Bouaké. Méthodes. Etude prospective, descriptive et analytique réalisée en pédiatrie au CHU de Bouaké du 05 octobre au 03 novembre 2022. Etaient inclus les agents dudit service, consentants, reconnus par la Direction des Ressources Humaines du CHU de Bouaké et présent durant la période de l'étude. Les variables étudiées étaient socioprofessionnelles et l'évaluation du SEP. Le SEP a été évalué à l'aide du Maslach Burnout Inventory (MBI). Résultats : Au total 70 participants dont 39 présentant un SEP (13 hommes, 26 femmes) soit une prévalence de 56%. Les facteurs signifi cativement associés au SEP étaient la situation matrimoniale (Célibataire) (p=0,004 ; OR 0,155 ; IC 0,043-0,563), et le statut d'agent journalier (p=0,024 ; OR 0,058 IC 0,005-687). Conclusion. Le SEP était très fréquent en pédiatrie du CHU de Bouaké. Il avait un lien étroit avec la situation matrimoniale et le statut d'agent journalier. Pour améliorer la situation nous recommandons un accompagnement psychologique du personnel ainsi que la revalorisation salariale et des conditions de travail des agents journaliers. Mots clés : -Syndrome d'épuisement professionnel; -Hôpital; -Pédiatrie, -Côte d'Ivoire. ABSTRACT Background and object

Background and objective. Burnout syndrome (BWS) is a particularly worrying pathology in the hospital environment with a negative impact on the quality of care. The objective of the study was to determine the prevalence and main factors associated with burnout among paediatric health care staff at the University Hospital of Bouaké. Methods. Prospective, descriptive and analytical study conducted in pediatrics at the University Hospital of Bouaké from October 5 to November 3, 2022. The study included consenting staff of the said department, recognised by the Human Resources Department of the University Hospital of Bouaké and present during the study period. The variables studied were socio-professional and SEP evaluation. The BWS was assessed using the Maslach Burnout Inventory (MBI). Results. A total of 70 participants, 39 of whom had MS (13 men, 26 women), representing a prevalence of 56%. The factors significantly associated with MS were marital status (single) (p=0.004; OR 0.155; CI 0.043-0.563), and day worker status (p=0.024; OR 0.058 CI 0.005-687). Conclusion. The SEP is very frequent in the paediatric ward of the University Hospital of Bouaké. It is closely related to marital status and day labourer status. To improve the situation, we recommend psychological support for the staff as well as an increase in the salary and working conditions of day workers.

Dépistage de la stéatose hépatique par le Fibroscan/CAP chez les sujets noirs africains porteurs d'une Hépatite Virale B chronique en Côte d'Ivoire / Fibroscan/CAP screening for hepatic steatosis in black African subjects with chronic Viral Hepatitis B in Ivory Coast

Context and objectives As the global epidemic of obesity and metabolic syndrome progresses, the coexistence of fatty liver disease in patients with chronic viral hepatitis B (VHB) becomes significant. The objective of this work was to determine the frequency of hepatic steatosis assessed by Fibroscan/CAP (Controlled Attenuation Parameter) in patients with chronic VHB in Côte d'Ivoire. Methods. The study included 83 patients with chronic VHB. These were black patients who had performed a Fibroscan/CAP during the recruitment period and were willing to participate in the study. Patients with significant alcohol consumption, a secondary cause of hepatic steatosis, another liver disease regardless of the etiology associated with VHB were not included. Results. The frequency of hepatic steatosis in chronic HBV carriers assessed by CAP in our study population was 48.19 %, including 24.10 % of severe steatosis. Obesity was statistically correlated with the presence of steatosis in our patients. Patients who had steatosis on ultrasound were 5 times more likely to have steatosis on CAP. Significant fibrosis was insignificantly associated with steatosis. Conclusion. The frequency of fatty liver disease detected by fibroscan/CAP is high in patients with chronic VHB.

Contexte et objectifs Avec la progression de l'épidémie mondiale d'obésité et du syndrome métabolique, la coexistence d'une stéatose hépatique chez les patients porteurs d'une hépatite virale B chronique devient non négligeable. L'objectif de ce travail était de déterminer la fréquence de la stéatose hépatique chez les patients porteurs d'une hépatite virale B (HVB) chronique. Méthodes. Il s'agissait d'une série des cas de HVB de race noire, ayant réalisé un Fibroscan/CAP pendant la période du recrutement et consentants à participer à l'étude. Les patients ayant une consommation d'alcool significative, une cause secondaire de stéatose hépatique, une autre hépatopathie quelle que soit l'étiologie associée à l'hépatite B n'ont pas été inclus. Résultats. Quatre-vingt-trois patients porteurs d'une HVB ont été inclus. La fréquence de la stéatose hépatique chez les porteurs du VHB chronique était de 48,19 % dont 24,10 % de stéatose sévère. L'obésité était statistiquement corrélée à la présence d'une stéatose chez nos patients. Les patients qui avaient une stéatose à l'échographie étaient 5 fois plus à risque d'avoir une stéatose au CAP. La fibrose significative était associée de façon non significative à la stéatose. Conclusion : Près de la moitié des patients porteurs d'une hépatite virale B chronique présente une stéatose hépatique.

Analyse du coût économique direct du cancer du sein en Côte d'ivoire en 2022 / NA

La prise en charge du cancer du sein constitue un fardeau économique important dans les pays àressources limitées. L'objectif était d'estimer les coûts médicaux directs des patientes suivies pour un cancer du sein en côte d'ivoire Une étude transversale a été conçue et réalisée dans les principales structures sanitaires de référence en gynécologie-obstétrique et en oncologie en Côte d'Ivoire. L'étude incluait les patientes avec un cancer du sein confirmé par l'histologie. Les données ont été recueillies à partir des dossiers médicaux et des entretiens avec les patientes. Au total, 102 patientes à différents stades de la maladie ont été incluses dans l'étude. Les coûts augmentent aux stades avancés. La chimiothérapie était le principal facteur de coût (3 121 $ par patiente) avant la radiothérapie (1 714 $). Les femmes atteintes d'un cancer du sein ont dû faire face à un coût moyen estimé à 442 $ (allant de 322 $ à 933 $). Le coût de la radiothérapie était également exorbitant (1 714 $ par patient). La chirurgie était le traitement le moins onéreux (1 416 dollars). Le coût total moyen des examens radiologiques et des tests de laboratoire s'élevait respectivement à 304 et 247 dollars. Les soins de suivi ont été estimés à 631 dollars. Cette étude fournit une analyse perspicace qui servira de base à une évaluation économique plus poussée et pourrait également être utile aux décideurs en matière de santé pour l'inclure dans le plan national de couverture de la santé.

The management of breast cancer is a major economic burden in countries with limited resources. The aim was to estimate the direct medical costs of patients treated for breast cancer in the Ivory Coast. A cross-sectional study was designed and carried out in the main referral health facilities for gynaecology-obstetrics and oncology in the Ivory Coast. The study included patients with histologically confirmed breast cancer. Data were collected from medical records and patient interviews. A total of 102 patients at different stages of the disease were included in the study. Costs increase in advanced stages. Chemotherapy was the main cost factor ($3,121 per patient), followed by radiotherapy ($1,714). Women with breast cancer faced an estimated average cost of $442 (ranging from $322 to $933). The cost of radiotherapy was also exorbitant ($1,714 per patient). Surgery was the least expensive treatment ($1,416). The average total cost of radiological examinations and laboratory tests was $304 and $247 respectively. Follow-up care was estimated at $631. This study provides an insightful analysis that will serve as a basis for further economic evaluation and could also be useful to healthcare decision-makers for inclusion in the national health coverage plan.

Knowledge and management of WEEE by independent repairers in the city of Bouake in a context of health and environmental risk, 2022

Studies on waste management in Côte d'Ivoire are mostly focused on household and solid waste. It is appropriate to take a sustained look at the management of electrical and electronic equipment waste to better guide policies in this area. This work is a cross-sectional study covering the period from April 1, 2022 to June 30, 2022. The aim was to determine the knowledge and practices of the independent electrical and electronic repairers of the city of Bouaké in terms of electrical and electronic equipment waste (WEEE) management. A comprehensive sample of 307 people was interviewed by means of a questionnaire. The repairers interviewed had already heard of WEEE in 47.2% of cases. They had a good level of knowledge of WEEE in 85.5% of cases. In the final model in multivariate analysis, only the possession of a radio set at home had a significant influence on knowledge of WEEE. Repairers were unaware of the existence of D3E management legislation in 60.7% of cases; apart from humans (84.8%) who were most exposed to the dangers of inappropriate management of WEEE, other entities (air, soil, water, animals) would be polluted according to 36.6, 35.2, 4.1, and 3.4% of repairers, respectively. The most feared type of harm reported is injury (95.65%). Subjects dumped WEEE in a municipal landfill in 32.4% of cases. Sale, empowerment of pre-collection agents, and handing over to a recycling professional, cumulatively represent the most common practice (66.9%).

Adolescents infectés par le VIH au cours de la transition des soins pédiatriques aux soins pour adultes dans un hôpital de référence à Abidjan (Côte d'Ivoire). Etudes des caractéristiques cliniques / Hiv-infected adolescents during the transition from paediatric to adult care in a referral hospital in abidjan (cote d'ivoire). Clinical characteristics study

Les adolescents vivant avec le VIH ont de moins bons résultats que les adultes en matière de soins, en particulier lors de la transition entre les soins pédiatriques et les soins aux adultes. L' Objectif était de décrire les particularités socio familiales, cliniques, para cliniques et thérapeutiques des adolescents au cours de cette phase charnière de leur prise en charge. Méthodes. Il s'agissait d'une étude rétrospective à visée descriptive qui s'est déroulé du 1er au 31 mars 2020 (1 mois) sur la cohorte d'enfants vivant avec le VIH suivi au CHU de Cocody (Abidjan) de novembre 2005 à mars 2020 (15 ans). Résultats. Trente-huit adolescents en phase de transition ont été inclus. L'âge moyen était de 17 ans avec des extrêmes de 15 et 20 ans. Le sex ratio était de 1,37. La majorité des enfants étaient scolarisé (81,57%) avec un retard scolaire chez plus de la moitié (58%). Près de la moitié des cas était orphelin d'un ou des 2 parents (47,4%). Les conditions socioéconomiques étaient modestes ou défavorable (73,7%). Près de la moitié des adolescents était suivi depuis plus de 10 ans (42%). Un surpoids a été retrouvé dans 21% des cas. On notait un échec immunologique dans 10,5% des cas et un échec virologique dans un tiers des cas (31,6%). L'observance était moyenne ou mauvaise chez près de la moitié des adolescents (44,7%). La majorité des adolescents (94,7%) n'avait jamais eu de contact avec un médecin d'adulte. Conclusion. La transition des soins pédiatriques aux soins pour adulte est un processus au cours duquel l'adolescent est confronté à des diffi cultés socio familiale et scolaire, a l'inobservance avec échec thérapeutique qui doit être repéré de façon précoce. Le succès de cette étape nécessite également le rapprochement entre pédiatres et médecins d'adultes pour une prise en charge optimal des patients.

A questionnaire was used to collect data on socio-demographic, gyneco-obstetrical characteristics, knowledge and attitudes and he use of contraceptive methods. The chi-square test was used to measure the associations between the use of contraceptive methods and each of the characteristics studied

Microbiological and Nutritional Quality of Complementary Foods for Children (6 to 24 months) Produced in the City of Man (Côte d'Ivoire)

This study aims to determine the microbiological and nutritional quality of complementary foods for children produced in the city of Man (instant flour and porridge). To do this, a structured survey of nannies and vendors, coupled with microbiological and physicochemical analyzes was carried out. To this end, a questionnaire survey was conducted among nannies and porridge sellers in order to collect information on the use of complementary foods and to assess the state of cleanliness of the sales environment. A study of physicochemical (carbohydrates, lipids, humidity, ash, minerals) and microbiological (total aerobic mesophilic flora, yeasts and molds, total coliforms, Escherichia coli, Staphylococcus sp. and Salmonella sp.) characteristics using standard methods and referenced was then conducted to assess the nutritional value and health status of the porridges (Millet, Kokobaka, Anagobaka) and flours from the Focolari center consumed in Man. The survey data showed that the majority of the of nannies (61.1%) give a complementary food before the age of introduction (6 months), with regard to the saleswomen (100%) unaware of the proportion of the components and their nutritional intake as well as 54.8% of them have an unhealthy work place and environment. The microbiological analysis carried out on the 50 samples revealed a potential contamination of spoilage and pathogenic germs. The contamination rate of Anagobaka porridge is very worrying unlike other porridges and flours, especially with the presence of salmonella, the high rate of Escherichia coli and Staphylococcus aureus respectively (3.91×103 ± 0.09 and 5.34×104 ± 0.10 CFU/mL).) Regarding the nutritional analysis, there is a content of carbohydrates (70.17-85.08%), lipids (6.93-10.40%) and iron (30.64-64.34%) higher than those recommended by the FAO/WHO standard in the 6 types of samples analyzed. However, the zinc content is below this standard in all the samples tested. However, zinc deficiency is one of the main causes of stunted growth in children. All these results have shed light on the existence of a potential health risk and possible nutritional deficiencies in infants and young children who consume locally produced complementary foods.

Polymorphism Evaluation of TLR2 Gene Associated with Endometritis Infection in Buffalo Reared in Egypt

Aims: The objective of this study is to monitor the evolution of organochlorine residues levels in kola nuts collected from various actors in the eastern producing region of Côte d'Ivoire. Study Design: Kola nuts samples were collected from farmers, collectors and urban stores in the Eastern of Côte d’Ivoire. Place and Duration of Study: Health Department of Hydrology Health and Toxicology, Training and Research Unit of Pharmaceutical and Biological Sciences, Abidjan, Côte d’Ivoire, running 2016-2019. Methodology: A total of 225 samples were analyzed using Gas chromatography–tandem mass spectrometry (Agilent 7010B Triple Quadrupole GC/MS System). Results: Data showed that all 21 pesticides analyzed were detected in kola nuts samples. Statistical analysis indicated no significant difference in OCPs sub-group used by actors during the three-crop studied. The mean levels of HCHs, DDTs and cyclodienes were ranged from 5±1– 136.67±77.3 µg/kg FW, 5±1 – 116.67±63.2 µg/kg FW and 5±1 - 145±63.2 µg/kg FW, respectively. Otherwise, farmer’s levels of OCPs were lower than those detected in kola nuts from collectors and urban stores samples. Thus, compared to the MRL set by the World Health Organization/Food and Agricultural Organization, the farmer’s samples are lower than limits fixed, unlike the contents registered with collectors and urban stores. In the latter, nearly 80% to 100% of kola nuts collected are contaminated with hexachlorinated residues (HCHs) and heptachlor. Conclusion: There is the need to keep monitoring ecotoxicological chemical substances in kola nuts produced in Côte d’Ivoire and take steps that ensure health safety of end users. Care should be taken since residues could pose chronic health risk for adults and children.

High vectorial transmission of malaria in urban and rural settings in the northern, western and eastern regions of Côte d’Ivoire

Background & objectives: Malaria remains a public health problem in Côte d’Ivoire. To cope with this issue, the Ministry of Health established strategies through Long-Lasting Insecticidal Nets (LLINs) and artemisinin-based medicines. To better understand the influence of periodic mass distribution of LLINs on malaria transmission, this entomological survey was conducted in three regions of Côte d’Ivoire. Methods: Mosquitoes were sampled by Human Landing Catches (HLC) in urban and rural settings of Korhogo, Man and Abengourou. Mosquitoes were identified morphologically and by molecular methods. Plasmodium falciparum infection was assessed by ELISA, and the Entomological Inoculation Rates (EIR) were calculated for each species and setting. Results: Only An. gambiae s.l. was identified in Korhogo and in Abengourou while An. gambiae s.l. and An. funestus s.l. was reported in Man. An. coluzzii was the most abundant species of the An. gambiae siblings collected in Abengourou, and in Man while An. gambiae was most abundant in Korhogo. In urban settings, malaria vectors showed high aggressiveness (>11 bites per person per night) and the annual EIR was high (83.22-438.44 infectious bites per person per year). In rural settings, malaria vectors showed also high aggressiveness (19-52 b/p/n). The annual EIR is very high (>94 ib/p/yr). However, the weakest EIR was recorded in the northern region with 94.90 ib/p/yr. Interpretation & conclusion: This work indicates that malaria transmission remains high and heterogeneous across Côte d’Ivoire, despite repeated mass distribution of LLINs. Also, in Man, malaria transmission is more intense with the involvement of two main vectors. Furthermore, in the village of Korhogo, the EIR remained relatively low.

Evaluation of the Nutritional Quality of Supplemental Porridges Enriched with Vegetable Cortea (Corchorus olitorius) and Cashew Kernel (Anacardium occidental) for Moderately Malnourished Children Aged 6 to 59 Months

This study aims to improve the nutritional quality of traditional porridge intended for young children with moderate malnutrition. The biochemical and nutritional characteristics of three supplement porridges enriched with dried leaves Corchorus olitorius and Anacardium occidental were determined according to standard methods. The results revealed that enrichment with these two ingredients significantly improved the proportion of dry matter of porridges enriched with high contents in those containing only Western Anacardium BC2 (17.33 ± 0.83%) and that enriched with both Corchorus olitorius and Anacardium occidental BC4 (18.0 ± 0.5%) compared to the traditional non-enriched porridge BC1 (13.23 ± 0.41%) and that enriched with Corchorus olitorius only BC3 (14.63±0.56%). With regard to fat, the three enriched porridges showed significantly high levels: 16.00±0.00% (BC2); 13.75±0.25% (BC3); 19.25±0.35% (BC4) compared to porridge BC1 (12.75±0.25%). As for carbohydrates, enrichment did not lead to a significant increase in levels. On the other hand, the levels of proteins experienced a significant increase between 2.66 ± 0.08% (BC3) and 3.08 ± 0.05% (BC4). All the porridges showed high energy densities with values ​​ranging between 463.43±1 Kcal/100 g (BC1) and 488.21±1 Kcal/100 g (BC4). Regarding micronutrients, the results indicated a significant increase in trace elements with higher mineral values ​​in the porridge BC4 (Zinc: 05.05±0.06) and BC3 (Calcium: 60.91±0.07 mg /100 g; Iron: 21.80±0.20 mg/100 g; Copper: 01.57±0.04 mg/100 g; Phosphorus: 280.41±0.48 mg/100 g). The contents of fat-soluble vitamins, in particular vitamin A (BC2: 25.10±0.14 µg/100 g; BC3: 41.00±0.45 µg/100 g; BC4: 33.59± 0.12 µg/100 g) and water-soluble vitamins B2 (BC2: 12.39±0.01 mg/ 100g; BC3: 10.81±0.01 mg/100 g; BC4: 15.01±0.01 mg/100 g) and B9 (BC2: 23.05±0.25 mg/100 g; BC3: 27.13±0.29 mg/100 g; BC4: 35.16±0.36 mg/100 g) experienced a significant increase in the enriched porridge compared to the control. There is also a significantly high content of essential amino acid (leucine) with values ​​between (37.78±0.05 and 78.31±0.9 g/100 g) in the enriched porridge compared to the control (18.51±0. 05 g/100 g). All the porridges are very rich in essential fatty acids, linoleic acid (Ω6) with contents between 19.73±0.01 and 22.59±0.01 g/100 g and linolenic acid (Ω3) with contents between 01.20±0.00 and 07.95±0.00 g/100 g, and this in accordance with the recommended values ​​for moderate acute malnutrition (MAM). This nutritional supplementation also significantly improved their antioxidant properties with DPPH values ​​varying between 47.52±3 and 56.91±1.55% compared to the control (41.58±4.34%). Enriching these porridges with Corchorus olitorius and Anacardium occidental improved their nutritional quality in accordance with the recommended dietary intakes for my moderately malnourished for most essential nutrients. These enriched porridges could then be recommended not only for the nutritional rehabilitation of MAMs and also to prevent certain chronic diseases such as obesity and cardiovascular diseases.
