Objective: To study the place of simulation in the learning of newborn resuscitation among seventh year medical students at the University Hospital of Bogodogo in Ouagadougou, Burkina Faso. Material and Method: Our study took place in the obstetrical gynaecology department of the University Hospital Centre of Bogodogo (UTH-B) from 15 December 2018 to 15 March 2019. We randomly selected two groups of students, with no stimulation. We recorded a theoretical questionnaire to all students at the beginning and then carried out two stimulation sessions at 1 month intervals in the competence laboratory of the National School of Public Health. Then we evaluated the theoretical and practical progress of the students over time. We analyzed our data through the Epi info software in version 3.5.1. Results: The two simulation sessions positively influenced the theoretical knowledge of neonatal intensive care for 7th year students (p = 0.0391). Neonatal resuscitation management by students is better from one simulation session to another with a statistically significant difference (p = 0.0001). Conclusion: Our study of 7th grade students showed the importance of this tool in their practical training at the University Hospital of Bogodogo. Advocacy must be organized for its acquisition in the university hospitals of Burkina Faso.a.>a.>a.>

The present study wa. ca.ried out on sma.l-sca.e gold mining sites in the Ya.uré region of Côte d’Ivoire. This region is geologica.ly representa.ive of the Birimia. forma.ions (2.1 Ga. of West a.rica.

To this end, a.sa.pling ca.pa.gn wa. ca.ried out, resulting in the collection of 20 mining wa.te sa.ples a.a.yzed by X-ra. fluorescence spectrometry (XRF) a.d 10 by X-ra. diffra.tometer (XRD). The XRF a.a.ysis detected 06 predomina.t TMEs: a.senic, chromium, copper, nickel, zinc a.d va.a.ium. Sta.istica. a.a.ysis wa. ca.ried out to determine the distributions a.d correla.ions between these ETMs. To a.sess conta.ina.ion a.d/or pollution levels, the following indices were ca.cula.ed on the ba.is of reference concentra.ions of upper continenta. crust MTEs: Enrichment Fa.tor, Geo-a.cumula.ion Index, Concentra.ion Fa.tor, Degree of conta.ina.ion a.d those rela.ed to ecologica. risks. The results of sta.istica. a.a.yses a.d indices ha.e shown tha. a.senic a.d chromium a.e the most predomina.t a.d ca. be, depending on the chemica. form, potentia.ly more toxic. The results of the DRX a.a.ysis show the occurrence of severa. minera.s ca.rying these two MTEs, especia.ly tha. of a.ra.e minera., Stenhugga.ite, a. a.senic oxide linked to hydrotherma. veins.
