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%).

Knowledge and attitudes of health workers in bouake, Cote d'ivoire on zika virus disease in the context of a global epidemic

Since January, 2012, the Pacific region has faced a heavy burden of concurrent epidemics of dengue, chikungunya, and zika virus infections. In 2016, WHO developed a global response strategic framework to ensure that zika virus is a priority and accelerated area of public health research. This study conducted in Bouaké (Côte d'Ivoire) is part of this framework. The main objective was to assess the knowledge and attitudes of health workers working there on the zika virus disease in order to consider a better preparation and response to a possible epidemic in Côte d'Ivoire. Cross-sectional study covering the period from October 2016 to March 2017 was used here. The sampling was comprehensive and included interviews with 258 persons. Subjects were interviewed using a questionnaire edited and adapted from the CAP questionnaire developed by WHO in 2016. People with prior knowledge of the zika virus disease represented 66.3% of the health workers surveyed. Their level of knowledge was insufficient in 83.5% of cases. Their attitudes were good in 51.5% of cases. In the authors' final model, the exercise structure which was adjusted to the level of education and the corporation significantly influenced health workers' attitudes toward illness. Health workers in public settings appeared to have a better attitude compared to their private colleagues (adjusted OR = 4.88; CI: 2.37-10.03; p-value:0.000). The zika virus disease has attracted the attention of the medical community during the 2014-2016 period. This attention, while mitigated by the West African Ebola virus epidemic, deserves to be highlighted.

Problems of clinical diagnosis and treatment of P. falciparum malaria in Russian Federation.

AIM: To study the causes of falciparum malaria deaths in Russian Federation and to optimize therapy for severe forms of the disease. MATERIALS AND METHODS: The analysis of falciparum malaria cases with deaths recorded in Russian Federation from 2013 to 2017 was conducted. The results of optimization of pathogenetic therapy of severe forms of falciparum malaria for the prevention of adverse outcomes in the intensive care unit of the Infectious Clinical Hospital №2 of Moscow in 44 patients with severe course are presented. Treatment, clinical laboratory and instrumental investigations were carried out in accordance with our intensive care protocol, which took into account the current WHO recommendations. RESULTS: From 2013 to 2017 there were nine deaths from falciparum malaria reported in patients from African countries (6) and India (3). In Russia, due to the lack of effective drugs of artemisinin group, quinine with tetracycline or doxycycline is used for etiotropic therapy of patients with complicated form of falciparum malaria. In the management of such patients, the basis for treatment was the prevention of ischemic, reperfusion injuries of organs and hemorrhagic complications. In the infectious clinical hospital №2 of Moscow, since 2007, the intensive care unit has developed and tested a protocol for intensive therapy in patients with severe and complicated forms of falciparum malaria, including preventive methods of extracorporeal hemocorrection with prolonged veno-venous hemodiafiltration therapy and plasmapheresis, as a result of which the mortality rate decreased from 84 to 6.8. CONCLUSION: The country's lack of anti-malarial drugs, the insufficient awareness of the population about the risk of infection and measures to prevent malaria, late referral of cases for medical care and errors of clinical diagnosis and treatment annually lead to fatal outcomes. In such situation, the experience of optimizing the treatment of severe falciparum malaria is particularly useful, allowing decreasing the mortality.

[Current situation of primary prophylaxis with isoniazid (INH) in children who are contacts of patients with bacillary pulmonary tuberculosis in Abidjan (Cote d'Ivoire)]. / Situation actuelle de la chimioprophylaxie primaire à l'isoniazide (INH) chez les enfants contacts des patients atteints de tuberculose pulmonaire bacillifère à Abidjan (Côte d'Ivoire).

INTRODUCTION: The National tuberculosis program (NTP) in Ivory Coast recommends that children under 5 years living in a family environment with contagious tuberculosis patients, should receive Prophylactic treatment with INH (PTI), whatever the result of the tuberculin skin test (positive or negative) and their BCG status (vaccinated or not), at a dose of 5mg/kg/day for 6 months. We conducted this study to check the implementation of this recommendation in three support services of tuberculosis in Abidjan, the economic capital. MATERIAL AND METHOD: We conducted a multicenter, cross-sectional and descriptive study over 3 years (2011-2013), on consented patients, adolescents and adults aged at least 15 years, with a first episode of infectious pulmonary tuberculosis, in order to look for information on the INH prophylaxis in children under 5 years living under the same roof. We made patients interviews during their visit for bacteriological sputum controls at the second month of TB treatment. RESULTS: Of a total of 412 patients (53% males and 47% females) with a mean age of 34.5 years and with a low level of instruction (66.5%), we noticed 639 children under 5 years living under the same roof with them. Information on the screening of contact children was given to 71% of interviewed patients (291/412). Of the 339 children examined among 639 contacts, 234 (69%) had received only an intradermoreaction (IDR) and PTI was finally administered to 64% of them (217/339). CONCLUSION: High proportion of contact children under 5 not examined is a major concern for the NTP and a missed opportunity to prevent additional cases of tuberculosis among children.

[Detection of the IS2404 insertion sequence and ketoreductase produced by Mycobacterium ulcerans in the aquatic Heteroptera in the health districts of Dabou and Tiassalé in Côte d'Ivoire]. / Mise en évidence de la séquence d'insertion IS2404 et de la kétoréductase (Kr) produite par Mycobacterium ulcerans chez les Hétéroptères aquatiques dans les districts sanitaires de Dabou et Tiassalé en Côte d'Ivoire.

Buruli ulcer (BU) disease, caused by Mycobacterium ulcerans, is a major public health problem in Côte d'Ivoire. Until now, the mode of BU transmission was unknown, but recent studies implicate aquatic Heteroptera in the chain of transmission. This study was launched in Côte d'Ivoire to search for specific genetic markers for M. ulcerans in these bugs, including the insertion sequence IS2404 and ketoreductase (Kr), both involved in the synthesis of mycolactone, a toxin produced by these mycobacteria. Samples of aquatic Heteroptera were collected monthly with deep nets from ponds near villages in the health districts of Dabou and Tiassalé. After identification and enumeration of the bugs, batches of the same taxon underwent real-time PCR to search for the IS2404 target and Kr. Saliva of 69 specimens of Diplonychus sp randomly selected in the samples was also analyzed by PCR. In all, 283 single-taxon batches were created. Thus, PCR identified 26 batches belonging to the families of Belostomatidae, Naucoridae, Corixidae, Ranatridae, and Nepidae as positive for both targets. The IS2404 insertion sequence and Kr were present in 6 of the 69 samples analyzed in the saliva of Diplonychus sp. These aquatic Heteroptera suspected of infection by M. ulcerans might release it into the environment because of their ability to fly. They might thus be the source of human contamination.

Qualite de vie des eleves abidjanais : cas des eleves du lycee moderne Harris d'Adjame

"Introduction. En Cote d'Ivoire; la sante des eleves fait partie de la politique sanitaire; a travers le Programme National de Sante Scolaire et Universitaire (PNSSU). Cette etude avait pour objectif de decrire la qualite de vie des eleves d'un lycee de la ville d'Abidjan pour la promotion de la sante en milieu scolaire. Population et methode. Il s'agissait d'une enquete transversale a visee descriptive; realisee du 05 au 30 janvier 2008 au Lycee Moderne Nanguy Abrogoua (Abidjan). Un echantillonnage aleatoire systematique a permis de selectionner 770 eleves qui ont fait l'objet d'interview individuelle a l'aide d'un questionnaire standard. Resultats. Les eleves en majorite de sexe masculin (54;1%) avaient un age moyen de 16;5 ans avec un ecart type de 5;7 ans. Plus de la moitie des eleves (58;5%) residaient hors de la commune d'implantation du lycee. Plus du tiers des eleves (34%) affirmaient que les parents ne disposaient pas d'assez de moyens pour subvenir aux besoins de la famille. Par consequent; 22;7% faisaient de "" petits boulots "" pour financer leur etude et 25;6% affirmaient ne pas manger a leur faim. La majorite des eleves etait souvent angoissee (64;4%); deprimee (73;3%) et se sentait souvent mal dans la peau (68%). Ceux qui avaient des troubles du sommeil representaient 42;5% des enquetes. Pres de la moitie des eleves etait inquiete de leur sante (49;2%) et achetait les medicaments de rue pour se soigner (48;6%). En cas de probleme de sante; plus de la moitie (54;8%) ne frequentaient pas les services de sante scolaire par manque d'information (36;5%) ou par insatisfaction des soins recus dans ces services (24%). Parmi les eleves; 42;3% etaient sexuellement actifs et la sexualite constituait une source d'inquietude ou de preoccupation (48;9%) a cause du VIH-Sida (76;9%); des grossesses non desirees (54;4%). De plus; des comportements a risque tels que la consommation des medicaments vendu dans les rues (48;9%); la pratique du "" boro d'enjaillement (jeux perilleux consistant a s'adonner a des acrobaties et autres pas de danse sur le toit d'un bus en mouvement) "" (1;7%) et l'avortement (10;7%) etaient observes chez les eleves. Conclusion. La prise en compte de ces resultats pourrait contribuer a l'adoption de strategie visant a l'amelioration de la qualite de vie ou du bien etre des eleves; condition necessaire a un bon rendement scolaire.

[Antiphospholipid antibodies in African women presenting obstetrical complications]. / Anticorps antiphospholipides en gynécologie-obstétrique à Abidjan: intérêt diagnostique et pronostique.

The presence of antiphospholipid antibodies (APL) has been investigated in 68 African women presenting obstetrical complications versus a control group of 22 pregnant healthy women. Patients inclusion criterias were recurrent foetal loss, pre eclampsia, retroplacental haematoma and chronic foetal suffering. Eight of patients (11.8%) had a positive APL diagnosis, versus 0% in controls, using the combination of diluted thromboplastin test and Staclot LA These results argue for the systematic APL screening in African women with obstetrical complications, and could further improve the management of patients at risk.

Plasma TAFI antigen variations in healthy subjects.

The Thrombin Activatable Fibrinolysis Inhibitor (TAFI) is a recently described inhibitor of fibrinolysis. The physiological variations of plasma TAFI antigen are not well known. We studied TAFI antigen values in healthy populations with a commercially available kit from Milan Analytica (Switzerland). Broad range of TAFI antigen values (from 41% to 259%) was found in a population of 249 healthy individuals. Gender as well as pregnancy did not influence mean values of TAFI antigen. There was a positive correlation between TAFI antigen and age in female (r = 0.28; p <0.05) but not in male populations. Mean TAFI antigen value of a black African male group [mean +/- SD (range): 87 +/- 23 (39-144%)] was significantly lower than the one of age matched Caucasian men [114 +/- 34 (52-259%)] (p <0.0001). TAFI antigen values were very stable within individuals, they did not significantly vary on day time or at several months period. Thus, in contrast to large inter-individual variations, TAFI antigen levels are quite stable within individuals.

[Clinical trial of amodiaquine in the community of Attécoubé (Abidjan, Côte d'Ivoire)(May-December 1955)]. / Essai clinique de l'amodiaquine dans la commune d'Attécoubé (Abidjan, Côte d'Ivoire) (mai-décembre 1995).

A prospective study in the municipality of Attécoubé (Abidjan, Côte d'Ivoire) evaluated the sensitivity of P. falciparum to amodiaquine with a posology of 35 mg/kg over 3 days (1st day: 15 mg/kg; 2nd day: 10 mg/kg; 3rd day: 10 mg/kg) as well as its tolerance of this dosage. One hundred five WHO in vivo standard tests were performed over 7 days on subjects aged > 15 years from May to December 1995. The subjects were carriers of varying number of trophozoites: between 1000 to 34,000 trophozoites were recorded with a mean of 5193 trophozoites by microliter. We divided the subjects into two groups: group A with 43 patients to whom we administered medication and group B with 62 subjects who took their medication on their own. Clinical and parasitological verifications were made on D0, D2 and D7. Biological verification was conducted for 31 subjects of group A by mean of SGOT and SGPT quantity determination on D0 and D2. This survey revealed that 1.9% of P. falciparum malaria patients had precocious therapeutic failure to amodiaquine (35 mg/kg over 3 days) in this area. Clinical and biological tolerance was good and there was no difference between the two groups. We suggest that amodiaquine might be used for uncomplicated malaria at first intention in Abidjan.

Functional activity of protein C in liver cirrhosis and acute viral hepatitis on the Ivory Coast.

Protein C activity was determined in 70 patients with liver disease, 30 with acute viral hepatitis and 40 with liver cirrhosis. Statistical comparison of the values for patients with those for healthy Ivorians showed a significant decrease in protein C activity, positively correlated with a prolongation of the prothrombin time.

Connaissances, attitudes et pratiques des populations de Bouaké sur la maladie à virus Ebola, Côte d'Ivoire, décembre 2014

Introduction : Dès le début de la crise, le gouvernement ivoirien a pris des mesures conservatoires pour prévenir l'introduction de la maladie dans le pays et lancé un vaste programme d'éducation sanitaire de la population portant principalement sur le mode de transmission et les mesures d'éviction de la maladie. Bouaké, deuxième ville de Côte d'Ivoire au plan démographique avec une population de 680.694 habitants, est une ville carrefour, cosmopolite, lieu d'importants flux migratoires de communautés de la sous-région ouest-africaine. En prélude à la préparation à une éventuelle épidémie, nous menons cette étude sur les connaissances, attitudes et pratiques de la population de Bouaké face à la maladie à virus Ebola.Population et méthode : Nous avons mené une étude transversale à visée descriptive, du 8 au 28 décembre 2014, qui a permis d'interroger 352 chefs de ménages.Résultats : Tous (100%) les chefs de ménage avaient déjà entendu parler de la maladie à virus Ebola. La présence de l'affection dans les pays frontaliers à la Côte d'Ivoire a été rapportée par 89,8% (316/352) des sujets. Parmi les voies de transmission de la maladie, 94,32% (332/352) des personnes en ont trouvé au moins une. Outre la transmission de l'animal à l'homme, une transmission interhumaine était également rapportée. Il s'agissait du contact avec les liquides biologiques infectés par le virus Ebola (92,17%) ou d'un contact avec un patient souffrant ou décédé de maladie à virus Ebola (91,48%).En cas de contamination par la maladie à virus Ebola, les enquêtés se rendraient à l'hôpital (97,2%) et accepteraient l'isolement en milieu hospitalier (90,6%)
