Guide d'introduction à l'évaluation d'impact sur la santé en Suisse

Ce guide traite de l’Evaluation d’Impact sur la Santé (EIS) et des étapes du processus EIS. L’EIS est un outil novateur d’aide à la décision qui vise à évaluer les effets potentiels, positifs et négatifs sur la santé des politiques publiques, au travers de recommandations pour en maximiser les impacts positifs et atténuer les impacts négatifs. C’est le premier document qui décrit en détail le processus EIS en Suisse. Il se différencie des autres guides EIS existants dans la littérature internationale en ce sens qu’il découle directement des expériences réalisées par les Cantons (Genève, Jura et Tessin), cantons pionniers dans le domaine de l’EIS en Suisse

Obstetrical complications among adolescent girls at the maternity ward of Ignace Deen National Hospital

Background: The objective of this study was to highlight obstetrical complications that occurred among adolescent girls who delivered at the ward and to identify factors associated with the occurrence of such complications.Methods: This was a prospective study of descriptive and analytical type extending over a period of one year from September 1, 2016 to August 31, 2017 carried out at the maternity ward of Ignace Deen National Hospital at Conakry Teaching Hospital (CHU). It covered a continuous series of 1034 deliveries among adolescent girls.Results: The frequency of childbirth among adolescent girls was 16.7%. The main complications identified were dystocia, severe preeclampsia, eclampsia, retroplacental hematoma, placenta previa, uterine rupture, severe anemia, postpartum hemorrhage and puerperal endometritis. These complications occurred among adolescent girls aged 18 to 19, christian, skin and pelvic bones secondary school or university students. Factors associated with such complications were the marital status (p=0.010), the gestational age (p=0.012), the number of prenatal consultations (p=0.001), the place of prenatal consultation (p=0.001), the reason for admission (p=0.000) and the mode of admission (p=0.000).Conclusions: Childbirth among adolescent girls is frequent in this context; complications are numerous but they are preventable in the vast majority of cases

Evaluation of B3LYP, X3LYP, and M06-class density functionals for predicting the binding energies of neutral, protonated, and deprotonated water clusters

In this paper we assess the accuracy of the B3LYP, X3LYP, and newly developed M06-L, M06-2X, and M06 functionals to predict the binding energies of neutral and charged water clusters including (H_2O)_n, n = 2−8, 20), H_3O+(H_2O_)n, n = 1−6, and OH−(H_2O)_n, n = 1−6. We also compare the predicted energies of two ion hydration and neutralization reactions on the basis of the calculated binding energies. In all cases, we use as benchmarks calculated binding energies of water clusters extrapolated to the complete basis set limit of the second-order Møller−Plesset perturbation theory with the effects of higher order correlation estimated at the coupled-cluster theory with single, double, and perturbative triple excitations in the aug-cc-pVDZ basis set. We rank the accuracy of the functionals on the basis of the mean unsigned error (MUE) between calculated benchmark and density functional theory energies. The corresponding MUE (kcal/mol) for each functional is listed in parentheses. We find that M06-L (0.73) and M06 (0.84) give the most accurate binding energies using very extended basis sets such as aug-cc-pV5Z. For more affordable basis sets, the best methods for predicting the binding energies of water clusters are M06-L/aug-cc-pVTZ (1.24), B3LYP/6-311++G(2d,2p) (1.29), and M06/aug-cc-PVTZ (1.33). M06-L/aug-cc-pVTZ also gives more accurate energies for the neutralization reactions (1.38), whereas B3LYP/6-311++G(2d,2p) gives more accurate energies for the ion hydration reactions (1.69)

Post-operative maternal morbidity and mortality after caesarean delivery and laparotomy for uterine rupture at the gynecology and obstetrics service of the Ignace Deen National Hospital in Guinea

Background: The aim of the work was to study post-operative maternal morbidity and mortality after caesarean delivery and laparotomy for uterine failure, to describe the main causes and to analyze the risk factors.Methods: It was a descriptive, comparative and analytical study lasting 2 years with data collection in 2 phases, one of which was a retrospective study lasting one year from July 2018 to June 2019 and the other a prospective study also lasting one year, from July 2019 to June 2020. It concerned all pregnant women who had been caesarized or had had a laparotomy for uterine rupture with complications and those who had not developed any complications. The parameters studied were types of complications, risk factors and maternal mortality. The Chi-square test was used to compare the two populations with a significance level p=0.05.Results: During the study period, 6141 hospitalizations were recorded among which 5682 surgical procedures were performed, i.e. 92.52% of hospitalizations. Caesarean delivery accounted for 90.55% of surgical procedures and laparotomy for uterine rupture for 1.10%. The overall maternal post-operative morbidity rate was 7.60%. Post-operative anemia was by far the most common complication (75.76%) followed by infection (23.46%). The maternal death rate was 0.92% with a ratio of 409.97 maternal deaths per 100,000 live births and more than 2/3 of these deaths were due to caesarean delivery. Anemia and septic shock were the main causes of death. Factors related to this post-operative maternal morbidity were: age greater than or equal to 40 years, multi-parity, illiteracy, emergency obstetric evacuation, low socio-economic level, poor quality of prenatal follow-up and rupture of membranes before admission.Conclusion: In the emergency context concerning majority of our cesarean deliveries and the totality of uterine ruptures predispose the mother to high significant morbidity and mortality

Effet du chlorure de sodium sur la germination de graines de Ricinus communis L.

Ricinus communis L (ricin) figure parmi les espèces du Programme biocarburant au  Sénégal. Sa culture sur des terrains incultes (terres salées) constitue une alternative pour éviter une concurrence sur les terres à vocation agricole. C’est pourquoi le taux de germination (TG) de sept accessions de graines de ricin a été étudié pendant 15 jours sous des concentrations croissantes de NaCl (0; 20; 50; 80; 100; 150 et 200 mM). Les résultats ont montré une large variabilité de tolérance au sel au stade de la germination. Les accessions 3 et 8 ont été très sensibles avec des TG réduits seulement à la concentration 20 mM NaCl. Les accessions 1, 6 et 7 n’ont pas toléré la concentration 50 mM. L’accession 5 n’a toléré que les teneurs < 80 mM. L’accession 4 a germé dans les milieux ≤ 100 mM NaCl. Elle n’a manifesté une perte significative de TG qu’en présence de 150 mM NaCl. Elle a été la moins affectée par l’effet ralentisseur du sel sur la vitesse de germination. Ces résultats permettent de dire que le mode d’action de NaCl sur la germination est de nature osmotique et/ou toxique.Mots clés : Ricin, espèce, biocarburant, tolérance au sel, teneur en sel, Sénégal
