Vector-borne diseases are highly sensitive to environment and to environmental changes. Rift Valley Fever (RFV) is a mosquito-borne zootic virus associated with severe diseases in human beings and economic consequences to livestock sector. Animal and human movements have a fundamental impact on RVF transmission. In recent years, there has been a growing interest in the use of mathematics and agent based models to represent and analyze the dynamic of RFV transmission. However, no previous study has taken into consideration animal herds’ mobility and precipitation factors to understand the disease spread. This limitation underlines the necessity to use computational model approach based on multi-agent system in the study of vector-borne diseases transmission and diffusion. In this paper, a multi-agent system combining conceptual model expressiveness is used to study animal herds’ mobility and the precipitation parameter impact on the Rift Valley Fever outbreak in Ferlo Barkedji in Northern Senegal. Simulation scenarios with various parameters, including rain quality, hosts, vectors, camp dispersal around ponds, etc., are unrolled. The different results we have obtained show that the evolution of the number of infected hosts and infected vectors depend on the degree of animal herds’ mobility and on precipitations. Our model provides a framework that permits predicting the spread of the disease associated with the mobility of animal herds.

Guinea is confronted to the increasing risks of bushfires that destroy thousands of hectares of vegetation cover every year. Very little research is devoted to the variability of those fires, which makes it a serious threat to both wildlife and human habitats. The current study investigates the spatial and temporal distribution of bushfires in the period from 2003 to 2016. The method used is the geospatial technology: we first filter pixels corresponding with active light supplied by MODIS images (Moderate Resolution Imaging Spectroradiometer) and estimate their densities following the square meshing procedure. Burned areas are deducted from the estimated pixel densities by calculations. The results highlight great occurrence of fires: 4 to 48 pixels of active fire per year and per 100 km2 depending on the location;2 to 5 million hectares per year of burned areas (20,000 to 50,000 sqkm). Almost 8 to 24% the size of the whole country. The prefectures of Beyla, Siguiri, Kouroussa, Kankan, Dinguiraye, Mali and Tougué are the most exposed areas. Every year, fire activities are observed as from October and between May and June. They are however mitigated according to the regions (or the geographical domains). Summits of bushfires activities are generally reached between December and January.

Objective: To study the lipid profile among the diabetic and non-diabetic obese patients. Methods: It was a descriptive and prospective study carried out over a period of 9 months from March to December 2010. It concerned all the patients who came for consultation in endocrinology at the internal medicine of Point G University Hospital Center and at the National Center for Diabetes Research. All the patients were included without any gender or age difference, voluntary and with a BMI ≥ 30 kg/m2. Results: Out of the 1543 patients received in consultation, we had identified 178 obese people that is to say 11, 53% of the cases. Among these cases 60 abided by our criteria with 30 diabetic patients and 30 non-diabetic ones. The average age was 45.83 ± 14.68 years old;73.3% were more than 40 years old. The sex ratio was 0.07. Two third (66.7%) of our patients limited their eating diet to the three main meals/day and 61.7% were sedentary. The notion of family obesity was found in 93.4% of the cases, of family diabetes in 58.3% of the cases, of past personal medical history of hypertension in 43.3% of the cases. It was about an android obesity in 91% and Gynoid in 9% of the cases. The BMI was 55% of the cases comprised between 30 - 34.9 kg/m2. The lipid profile noticed was: A hypertriglyceridemia: 33% of diabetic patients and 10% of non-diabetic patients, a high LDL cholesterol: 37% of diabetic patients and 30% of our diabetic patients, a HDL hypocholesterolemia: 40% of the diabetic patients and 20% of the non-diabetic patients, a total hypercholesterolemia: 37% of the diabetic patients and 23% of non-diabetic patients. A hyperglycemia was noticed in 13.3% of non-diabetic patients. Conclusion: The frequency of metabolic troubles was higher in obese diabetic patients compared to non-diabetic obese patients mainly the hypertriglyceridemia.
