During the last decade, Jatropha curcas L. (J. curcas) has gained much attention worldwide as biofuel crop. Although its cultivation is promoted in the Sahel, there is a surprising lack of data on its water use regulation and growth in this region. Here, we investigated, in semi-controlled conditions, leaf transpiration and growth of six accessions of J. curcas at seedling stage under natural changing in vapour pressure deficit (VPD) and progressive soil drying in Senegal. The experimental layout was a randomized complete bloc design and after 3 months of growth arranged to a split-plot at the implementation of water stress to facilitate irrigation. Under well water condition, there was no significant difference between accessions for leave transpiration that was positively correlated to VPD with high values recorded between 13 h and 14 h pm. Accessions of J. curcas used in this study showed closed thresholds at which transpiration declined except accession from Ndawene that threshold was lower (0.30). There is no significant difference between accessions for growth during the experimentation period. In 3 months, we recorded 23.57 g for the aboveground dry biomass and seedlings had about 14 leaves and 24.3 cm height. Positive linear correlation was recorded between aboveground biomass and root dry weight (p J. curcas might need complement irrigation for a better growth of seedlings especially during the dry season.

Objectives: To identify predictive factors for poor prognosis during cerebral toxoplasmosis at Donka Hospital. Methods: It was a retrospective study of descriptive and analytic type lasting one year six months (18 months) from January 1st, 2016 to June 30th, 2017 which involved patients admitted and hospitalized for cerebral toxoplasmosis in HIV field. Data enter was performed by Epi data 3.1 software and SPSS 21 software for statistical analysis. The threshold of significance was p Results: We observed 87 cases of cerebral toxoplasmosis (CT). The mean age was 38.53 ± 12.16. The clinical signs were mainly infectious syndrome (100%), headache (69.0%), confusion (46.0%) and meningeal syndrome (41.4%). The lethality was 37.9%. Living with a partner (p = 0.007), CD4 at initiation of antiretroviral therapy 3 (p = 0.009), and coma (p = 0.02) were the factors associated with death. Conclusion: This study showed that cerebral toxoplasmosis is associated with very high morbidity and mortality in the Infectious Diseases Department of Donka National Hospital. Living in a relationship, CD4 counts at baseline 3 and coma were independently associated with death. Special attention to these factors associated with infectious resuscitation and primary prevention in patients with a CD4 T lymphocyte count below 200 cells/mm may improve the prognosis of this pathology.

Introduction: Acute myeloblastic leukaemia (AML) is a haematological malignancy with a poor prognosis, despite significant therapeutic progress. This study presents the results of AML management in Mali according to GFAOP recommendations. Methodology: This was a retrospective, cross-sectional study. It included patients aged 0 - 15 years treated in the paediatric oncology unit for AML and followed up between January 2016 and December 2020. Results: During the study period, 85 cases of acute leukaemia were diagnosed in the paediatric oncology unit (including 51 cases of ALL), of which 34 cases of AML were included in this study. The majority were boys (59%). The mean age was 8 years, with extremes of 18 months and 15 years. The mean time to diagnosis was 68 days. In 79% of cases, patients were referred by 1st or 2nd level hospitals. Anaemia was observed in 91% of cases, an infectious syndrome in 68%, haemorrhage in 56% and a tumour syndrome in 85%. The haemogram showed hyperleukocytosis in 15% of cases, thrombocytosis in 22% and severe anaemia in 73%. Death occurred in 85% of cases, most often in the context of sepsis or haemorrhage. Conclusion: AML is probably underestimated in Mali and diagnosis delayed, which may be explained by patient-related factors (lack of knowledge, financial constraints) and a cumbersome referral system. These results suggest the need to implement an appropriate diagnostic and therapeutic strategy, with strong involvement of the political authorities.

Neonatal Mortality Associated with the Referral of Low Birth Weight Newborns to the Institute of Child Nutrition and Health (INSE)

引用

Open Journal of Pediatrics 2019年第4期9卷 287-295页

作者： Diallo ibrahima Sory Diallo Sory Conté N’fanly Diawara ibrahima Bah Elhadj Mamoudou cissé Moussa Matthias Roth Kleiner Sy Telly Pediatrics Chair Gamal Abdel Nasser University Conakry Guinea Institute of Nutrition and Child Health Conakry Guinea Gyneco-Obstetrics Chair Gamal Abdel Nasser University Conakry Guinea Department of Women Mother and Child Lausanne Switzerland

The objective of this study was to identify risk factors and study the causes of neonatal mortality of LBW newborns referred to the Institute of Nutrition and Child Health. Material and Methods: This is a prospective descriptive and analytical study from March 1 to August 31, 2015, involving 250 newborns referred to the Neonatology Department of the Institute of Child Nutrition and Health (INSE). Results: During our study period, we recorded 1169 newborns, 250 of whom were referred, representing a referral frequency of 21.38%. The overall mortality rate for transferring newborns was 46.8%. Risk factors associated with neonatal mortality were gravidity (p = 0.0019), parity (p = 0.0323), occupational activities requiring physical effort (p = 0.0257), birth weight (p = 0.0008) and prematurity (p = 0.0039). Conclusion: Neonatal mortality associated with referrals is a major health problem in developing countries. There is currently no doubt that it is possible to significantly reduce perinatal mortality and morbidity rates by organizing the identification of “mother-child” couples at risk, to refer them intently to centres better equipped with technical and human resources to care for them.

In Senegal the aluminum scrap are mainly recycled kitchen utensils [1]. The craftsmanship poses the problem of the quality of finished products [1] especially when we know they are used for everyday cooking. Given that none of these alloys should not be used to make cooking utensils if we refer to the EN 601 standard in July 2004, which refers to this regard [1], this study aims at analyzing behavior of these alloys reconstructed in three settings (tap water, vegetable oil and salt water more than 3 grams per liter), chosen for their importance in Senegalese cuisine. Significant loss of mate- rial was observed mainly by intergranular corrosion. It would be interesting that additional studies be conducted to ex- amine the impact of the daily use of these alloys on the health of Senegalese.

The aim of this work is to map the susceptibility of sites to landslides. To assess the susceptibility of the zone, GIS techniques were used. Susceptibility factors are selected and split into two groups: active and passive factors. Passive factors regroup all the intrinsic conditions existing on the field at all times. The active factors or triggering factors are present sporadically and are added to the passive factors to trigger a landslide. With the weighted overlay method using ArcGIS?, four scenarios have been developed. A first scenario where only passive factors are combined and three scenarios for which we have for each scenario the passive factors combined with an active factor. With these different scenarios, five levels of susceptibility are obtained in the zone. These levels range from very low to very high susceptibility. For the different scenarios, the results show that the zone consists mainly of very low to low susceptibility with at least 61% of the area, followed by moderate susceptibility (23.54% to 38.24%) and last land with high susceptibility to very high with less than 1% of the surface. Fields with high to very high susceptibility are located on the slopes of the hills. Among the active factors, only the rainfall significantly modifies the percentage of land susceptible to landslide but remains in the field of moderate susceptibility. The predicted susceptibilities are closer to the observed landslides around the Thies Cliff than to the Dias Horst.

Introduction: The prevalence of Non-communicable diseases (NCDs) has increased so it’s becoming a global public health problem. This problem is also threatening in Sub-Sahara Africa (SSA) country including Ivory Coast. Ivory Coast is a country of 22.6 million people experiencing rapid economic development and social change. All development is typically associated with an increase in non-communicable disease (NCD) risk factors. Our study aimed to determine the prevalence and associated factors of the major risk factors of NCDs among the population of Cocody, Abobo and Yocoboué in the Ivory Coast. Methods: A descriptive and analytical cross-sectional study was conducted and involved 1146 adults of 19 to 60 years from general population in Cocody (urban), Abob (peri-urban) and Yocoboué (rural). The WHO STEPS risk factor survey has been changed a bit and was administered. it contains anthropometric and biochemical measures. Results: The prevalence of NCD risk factors was markedly different across the three sites particularly between urban (Cocody) and rural (Yocoboué) areas. The overall prevalence estimates of the risk factors were 15.2% for current smoking, 57.71% for harmful use of alcohol, 58.84% for low physical activity, 24.71% for sedentariness (sitting at least 7 h), 69.45% for skipping breakfast, 61% for having late dinner and 36% for snacking. Concerning biological risk factor we noticed 40.95% for Overweight/obesity, 52.96% for abdominal obesity, 14.61% for raised blood pressure, 23.37% for raised blood sugar and 18.51 low HDL-C.

The disorders caused by the swelling of the soil on the structures have been observed for several years in the city of Rufisque. This article presents the results of the study of swelling kinetics of expansive soils in Rufisque and their prediction based on the hyperbolic rule. The odometer is used as an instrument for measuring swelling and the tests are carried out on some intact samples at their sampling water content. The present study shows that in Rufisque the most swelling layer is marl. The results show two phases of development. The first phase is very fast and represents 77% of the final deformation and the second one is slower. The prediction of the issue by the hyperbolic rule shows that it underestimates the first phase but gives a good prediction of the second phase of the swelling rate. There is a good correlation between the final swelling rates. However, the model gives a bad approximation of the half-swelling time.
