Freshwater snail’s distribution related to environmental factors in Banco National Park, an urban reserve in Ivory Coast (West Africa)
I A Camara
African Zoology , 2012,
Abstract: Freshwater snails and environmental variables were studied at seven stations along the Banco River (C te d’Ivoire; West Africa) from March to October 2008. Two species (Physa marmorata; Physidae and Bulinus forskalii; Planorbidae) were recorded only at one sampling site. This station which received domestic sewage from the neighbouring cities was characterised by the highest conductivity and pH and the lowest values of dissolved oxygen. Multiple stepwise regression analysis showed that snail densities were probably influenced by conductivity, dissolved oxygen, pH, and canopy cover. Also, snail dynamics showed a seasonal pattern, with peak population densities and recruitment of young generations during rainy periods. This study highlighted the impacts of sewage on snail diversity and distribution in the Banco River. Overall, this paper strengthens the viewpoint that the Banco River management should be implemented to lessen the impact of anthropogenic activities on the ecology of the Banco National Park.

Surgical Science (SS) , 2015, DOI: 10.4236/ss.2015.67047
Abstract: The pulmonary artery dissection (PAD) is a rare and life-threatening event, usually secondary to a chronic pulmonary artery hypertension. We report the case of pulmonary artery dissection undergoing medical treatment by conservative management, discovered by performing a computed tomography (CT), and describe the clinical and therapeutic characteristics with the literature review.

International Journal of Geophysics , 2012, DOI: 10.1155/2012/972896
Abstract: Reliable climate change scenarios are critical for West Africa, whose economy relies mostly on agriculture and, in this regard, multimodel ensembles are believed to provide the most robust climate change information. Toward this end, we analyze and intercompare the performance of a set of four regional climate models (RCMs) driven by two global climate models (GCMs) (for a total of 4 different GCM-RCM pairs) in simulating present day and future climate over West Africa. The results show that the individual RCM members as well as their ensemble employing the same driving fields exhibit different biases and show mixed results in terms of outperforming the GCM simulation of seasonal temperature and precipitation, indicating a substantial sensitivity of RCMs to regional and local processes. These biases are reduced and GCM simulations improved upon by averaging all four RCM simulations, suggesting that multi-model RCM ensembles based on different driving GCMs help to compensate systematic errors from both the nested and the driving models. This confirms the importance of the multi-model approach for improving robustness of climate change projections. Illustrative examples of such ensemble reveal that the western Sahel undergoes substantial drying in future climate projections mostly due to a decrease in peak monsoon rainfall.

Abstract: Shrimps are an important component of river invertebrate assemblages in tropical freshwater where they are a controlling group in food webs. In order to determine shrimp diversity in the Banco Basin (C te d’Ivoire, West Africa) and examine whether the patterns of species distribution were related to environmental conditions, six sites were monitored. Sampling was conducted in 2008 during February, May, September and November using a long-handled net (25-cm diameter, 2-mm mesh). For each site, we measured environmental variables (conductivity, pH, water temperature, dissolved oxygen, turbidity, current speed, and water depth and width). Three shrimp species, Macrobrachium thysi (Powell 1980), Macrobrachium dux (Lenz 1910) and Desmocaris trispinosa (Aurivillius 1898) were identified. D. trispinosa was the largest distributed (more than 50% of occurrence) and the most abundant (67% of total number of specimens caught). It was followed by M. thysi with 47% and 32% of occurrence and abundance, respectively. Canonical correspondence analysis (CCA) showed a spatial distribution of the shrimp community, significantly influenced by width, depth, conductivity, type of substrate, turbidity and dissolved oxygen. Due to the fact that the Banco River hosts an endemic species in C te d’Ivoire (Macrobrachium thysi), the conservation of integrity of this basin was recommended.

Introduction Addressing climate change over West Africa is a great challenge for understanding the effects of greenhouse gas (GHG) warming at local and regional scales. Such assessment is critical because Africa is mostly covered by semiarid regions known for their unreliable rainfall regime which is highly variable on intraseasonal, interannual and interdecadal time scales [1–3]. This variability often translates into severe droughts and floods [4] and may substantially impact food security and water resources. Therefore, changes in future climate may pose significant threats to the region especially in resource poor contexts where agriculture is a prominent instrument for enhancing food security, and adaptive capacity is relatively low [5]. The production of accurate and reliable climate change scenarios for the West African continent is therefore a major issue. In this region, climate change projections have been often derived using global climate models (GCMs) [6, 7]. However, despite the significant progress in climate modeling, projections over West Africa are limited by at least two factors. First, the West African monsoon precipitation response to anthropogenic climate change is uncertain [8, 9] because the spread among the

Abstract: Introduction: The partial ventricular atrioventricular canal is a congenital heart malformation of the ostium primum type of variable surface that can reach the single atrium where the interatrial septum is no more than a cephalic muscular vestige attached to the roof of the atrium. His diagnosis at the age of 73 is not a common situation. The interest of this clinical case that we report lies in the peculiarity of its mode of discovery and its evolution under medical treatment. Observation. He was a 73-year-old patient with no known cardiovascular risk factor and has since been at about 18 years of age with heart failure syndrome with progressive dyspnea, cough and edema of the lower limbs, but never explored for lack of financial means, and the evolution was enamelled by episodes of cardiac decompensation, the last of which dated back to 03/07/2018 justifying a hospitalization in our service. Cardiac ultrasound shows a partial atrioventricular canal. The care was medical. Conclusion: The atrioventricular canal is a congenital heart disease complex of poor prognosis.

Abstract:
Cervical cancer remains a major public health problem in Africa, particularly in Mali. The goal of this work was to investigate the epidemiological and clinical aspects of cervix cancer seen at the radiation therapy center. This was a descriptive study on the retrospective collection of data on patients found in the Radiation Therapy Centre of Bamako, for invasive cervical cancer be-tween April 2014 and April 2017. The average age of our population was 52 ± 12.5 years with extremes ranges from 18 to 95 years. The most represented age group was [50 - 65 years] with 44.2%. The predominant histological type was squamous carcinoma (CE) with 94.2%. Bleeding were found in almost all patients, most often associated with foul smelling hydrorrhea; 80.3% of our patients were stage III and 12.9% of stage IV according to the IFGO classifi-cation. Cervix cancer remains a major public health problem in Mali. The di-agnosis is often late, therefore, resulting in late care and unfavorable progno-sis. Sensitization, vulgarization of vaccination and systematization of screen-ing could be helpful in the fight against this cancer.

Abstract: Malaria is much more common in pregnant women, especially during the third trimester of pregnancy, causing congenital infestation. Acute and severe complications are noted, including malignant malaria access and maternal and fetal mortality. Method: This was a three-month descriptive and analytical multicenter study, running from 1st January to 31st March 2015, conducted in 16 maternity hospitals at different levels of the health system pyramid. Results: Out of a total of 1772 mothers recruited for this study, 276 cases were tested positive (umbilical cordon and newborn’s heel). Among them, we reported 130 cases tested positive at newborn’s heel with congenital infestation confirmed by sampling on day 0, with a frequency of 7.3%. The average age of the mothers was 26 ± 14 years. With a predominance in the 20 - 35 age group (4.7%). Among mothers who were not exposed to preventive intermittent sulfadoxine pyrimethamine (IPT/SP) in malaria prevention, 6.1% of newborns tested positive. Of these, mothers who had less than 4 prenatal visits during pregnancy had a congenital malaria rate of 7.3%. Conclusion: Congenital malaria infestation exists in newborns despite adequate measures used
