Evaluation of the Nutritional and Hematological Status of Sickle Cell Children Monitored in the Pediatric Department of the University Hospital Center of Yalgado Ouedraogo

Objective: To assess the nutritional and hematological status of sickle cell children followed in the department of pediatrics of the Yalgado Ouédraogo University Hospital Centre (CHU-YO).Methodology: This was a cross-sectional study conducted from September 1, 2017, to February 28, 2018. All children with major sickle cell syndrome followed in the department of pediatrics at the CHU-YO and following their follow-up appointments were included in the study.Results: We included 230 children aged 11 months to 16 years with an average age of 8.5 years. The sex M/F ratio was 1.09. The SC heterozygotes were the most represented with 56.52%. The average hemoglobin level was 9.39 g/dl. The prevalences of wasting, stunting and underweight were respectively 23.04%, 15.65%, and 13.89%. In univariate analysis, the factors associated with emaciation was hyperleukocytosis (p=0.002).The factors associated with stunting were leukocytosis (p=0.01), severe anemia (p=0.01), SS phenotype (p=0.002), age range of 5-10 years (p=0.007), Secondary (P=0.007) and higher level (p=0.001) of father’s education, secondary (p=0.027) and higher level (p=0.034)of mothers’education , farmer(p=0.003) trader (p=0.042), and informal occupation of father (p = 0.002),and breastfeeding duration after 24 months (p=0.006). For underweight associated factors in univariate analysis were SS phenotype (p=0.003) and severe anemia (p=0.01).Conclusion: The prevalence of different types of malnutrition deficiency of sickle cell children followed at CHU-YO was high. It is important to strengthen the nutritional monitoring of children with sickle cell disease for better management of the disease

Simuler les déplacements de piétons dans une station de métro : une approche à base d'agents

La marche à pied est aujourd'hui encore l'un des modes de déplacement les moins bien connus. Pourtant, au coeur de toute chaîne de déplacements, elle est partie intégrante des objectifs de la planification urbaine et de la gestion des espaces de transport, tels que les stations de métro. Mieux connaître les déplacements piétonniers dans ces espaces souterrains, pour y adapter les aménagements et en améliorer la sécurité, est en effet un objectif prioritaire, rendu difficile à atteindre à la fois par des conditions d'observation souvent peu favorables et des possibilités d'expérimentation souvent limitées. La simulation informatique offre, de ce point de vue, des perspectives considérables. Le modèle MAGE (modélisation de la mobilité par agents à grande échelle) a été construit dans cet objectif. Le modèle est décrit de manière détaillée, ainsi que son application à la station de métro de la gare Montparnasse à Paris. Un protocole expérimental permet
