Abstract: Introduction: Hypertension (HTN) is for many decades a worldwide major risk factor for cardiovascular disease.However, hypertension control rates are globally low in the world. Studies on observance have been published in Mali but there is to our knowledge no published data about HTN control rate. We therefore conducted this study to assess the control rate in short term after 3 months management and to look for factors associated with HTN control. Materials and Methods: This study designed as prospective was conducted in the cardiology department of the University Hospital Gabriel Touré (UH-GT) from March 24 to September 24, 2017. All outpatients aged 18 years and more who came for visit and with hypertension as diagnose were involved. All patients have consented to participate in the study. Sociodemographic and data on physical examination including measures for BP, height, weight, waist circumference (WC) and direct costs as reported by the patients were recorded. Patients were asked about medication discontinuation and if yes why and then they were informed about the need to take regularly medication. The concept of chronic disease was explained to them. A formulary served to collect data that were inserted into a Microsoft Access database and analyzed using SPSS version 18. After describing of sociodemographics and continuous variables, crosstabs and finally a logistic regression was performed to look for blood pressure control predictors. Results: There was no statistical difference in sociodemographics between older and newly diagnosed patients. At 3 months globally 40.90% (31.1 for old Patients and 09.8% for newPatients) of the sample

Abstract: Rastrococus invadens was the only reported mealybug species on the mango tree in Western Burkina Faso. This study aimed at carrying out the inventory and showing the importance and distribution of other mealybug species associated with the mango tree. It was also important to determine the periods of abundance of these species vis-a-vis R. invadens. For this purpose, the density of mealybugs was assessed in three study sites (Toussiana, Bérégadougou and Orodara) in Western Burkina Faso. The observations were made from June 2014 to June 2015 at a frequency of 15 ± 1 days. They focused on 20 leaves (5 leaves/cardinal point) levied on each mango tree. The species identified as Ferrisia virgata Cockerell and Icerya aegyptiaca Douglas were collected from mangos infested by R. invadens representing 98% - 99% of the density of the observed mealybug species. The periods of abundance of F. virgata and I. aegyptiaca were respectively the dry season and the rainy season. The effect of temperature, relative humidity and rainfall on the populations of F. virgata and I. aegyptiaca was also discussed. These results highlight the distribution range of F. virgata and I. aegyptiaca worldwide including Burkina Faso. R. invadens was the main mealybug species on mango in Burkina Faso in general and in the Western region of the country in particular.

Advances in Entomology (AE) , 2017, DOI: 10.4236/ae.2017.52005
Abstract: To understand the mechanism of infestation of stored groundnut in farming areas, studies on the inventory and geographical distribution of Caryedon species were carried out in the tree savannah and in producers’ storage structures. The incidence of C. serratus in stored groundnut was evaluated. Inventory and geographical distribution of insects belonging to Caryedon genus was achieved through a sampling in the savannah and producers’ granaries. The inventory and geographical distribution of insects was made throughout Burkina Faso whereas the evaluation of the perforations of groundnut pods was made in the western zone of the country. The results of the inventory showed the presence of two species belonging to Caryedon genus which are C. serratus and C. crampelii. These species are found on the agro-ecological zones of the country. The survival and maintenance of Caryedon species genus are ensured by the presence of plants belonging to various families such as Caesalpiniceae and Mimosaceae. The evaluation of the losses caused by C. serratus in producer’s stored groundnut revealed that the pods perforation rate varied according to the locality. In?Toussiana, the rate of perforated pods ranged from 53.72% to 100% in five months while in?Karangasso Sembla, for the same conservation time, the rate was in the range from 2.8% to 35%. However it is C. serratus which is responsible for the losses observed in the stored groundnut. Indeed, in the western area of Burkina Faso where more than 25% of the production is realized, 70% of

Abstract: L\'étude de l\'influence de la succession de quatre générations d\'une population de Cicadulina mbila Naude (Homoptera: Cicadellidae) sur la transmission du Maize Streak Virus (MSV) réalise au Burkina Faso a montre qu\'au cours des générations successives, l\'insecte vecteur voit son efficacité de transmission du virus diminuée de + 26% tandis que la période d\'incubation de la maladie augmente de 3,11 jours. Les femelles de la quatrième génération sont plus aptes a transmettre efficacement le virus (73,33%) que les males (57,21%). La période d\'incubation de la maladie est de 5,83 jours pour les femelles contre 6,16 jours pour les males. Cette étude a montre que le taux de transmission du virus obtenu avec les quatre générations de C. mbila, issues de l\'élevage artificiel, et est toujours supérieur au taux de 35% recommandé par l\'IITA et peut donc être accepté par les tests de sélection du ma s pour la résistance au virus du MSV. Mots clés: Cicadelles, élevage artificiel, ma s, générations, virus ABSTRACT The study of the influence of the succession of four generations of Cicadulina mbila Naude (Homoptera: Cicadellidae) on Maize Streak Virus (MSV) transmission in Burkina Faso showed that over successive generations, the insect vector loses its virus transmission efficiency by ± 26%, and the disease incubation period increases by 3.11 days. Females are more efficient in transmissing the virus (73.33%), than the males (57.21%). The disease transmission period is 5.83 days for the females compared to 6.16 days for the males. Finally, this study showed that the transmission rate obtained over four generations of mass reared C. mbila is always higher than the recommended rate of 35% for maize breeding and therefore, can be used in breeding for MSV virus resistance.

Abstract: The African Rice Gall Midge, Orseolia oryzivora H. & G., is an important insect pest recorded in 20 countries in Sub-Sahara Africa. In Burkina Faso, the insect pest particularly prevails in Western and South-Western of the country where both biotic and abiotic conditions favor its development. The insect pest can damage up to 60% of rice tillers in Western Burkina Faso. A study was conducted during the 2011 wet season in the Kou Valley, located 25 km North-West of Bobo-Dioulas- so, Western Burkina Faso. Its objective was to evaluate the damage of this insect pest in farmers’ fields in relation with rice transplanting periods. The Kou Valley rice scheme, 1200 ha, was divided into two zones within which 48 farmers’ fields were randomly selected in relation with rice transplanting periods: P1: 1st period; P2: 2nd period and P3: 3rd period; that is 16 fields per period. Both agronomic and entomological evaluations were performed each week starting from the 21th day after transplanting (DAT) up to 84 DAT. Results showed that the highest average damage level (16% of galls) was recorded in the 3rd transplanting period. The highest larval and pupal parasitism was recorded in P3 at 84 DAT. Pupal parasitism due to Aprostocetus procerae Risbec was higher than larval parasitism due to Platygaster diplosisae Risbec. Lastly, the lowest yield (4.78 t/ha) was recorded in P3. These results can be used in the implementation of an integrated pest management strategy for this insect pest in the Kou Valley.

The beetle Caryedon serratusOlivier is a major insect pest responsible for the infesta-tion and damage on groundnut during storage. To understand the infestation mecha-nism of groundnut stocks, studies have been carried out on this insect biology under laboratory conditions in relation with its host plants. The results have demonstrated that the pre-oviposition on groundnut lasts on average 1.28 days. The oviposition pe-riod is 12.04 days, during which 80.42 eggs on average are laid. From hatching to adult stage, C. serratus larvae development goes through four stages with variable durations according to the stage. Three families of host plants (Papilionaceae; Caesalpiniaceae and Mimosaceae) were selected for females C. serratusto lay on their seeds. The re-sults showed that more eggs were laid on the seeds of Papilionaceae (98.75% of in-fested seeds) followed by Caesalpiniaceae (28.59% of infested seeds). Studies were carried out on the laying behavior of C. serratus under laboratory conditions and have revealed that whatever the conditions, C. serratus?females lay on all the plant species seeds exposed. Insects’ development duration has varied according to the plant species seeds used.

Abstract: Prevalence of Bacterial Stripe Organism, Acidovorax avenae subsp. avenae, in Breeder Rice Seed Samples from Burkina Faso. Nine rice seed samples of improved and local varieties were tested at DGISP (Denmark) for the incidence of seed-borne bacterial stripe organism, Acidovorax avenae subsp. avenae, using the cassette holder method. Twenty-six suspected bacterial colonies were identified by different methods including colony morphology, pigmentation, biochemical and pathogenicity tests. Using Biolog GN computer identification system, isolates were also identified as A. avenae subsp. avenae (sim 0.51 to 0.9). All the 26 isolates reacted positively in ELISA tests performed with antiserum against A. avenae subsp. avenae. The bacterium was detected in all the samples, except in that of the local variety, indicating that seeds of improved varieties are highly infected by this pathogen. Seedlings raised from infected seed samples showed typical bacterial stripe symptoms with infection rates ranging from 4.7 to 20.1%. Since such seeds are used for production of certified rice seed, it is important to develop an effective control strategy against this disease to reduce the propagation of the bacterial agent in other healthy regions of rice culture in Burkina Faso.

Abstract: The objective of our study was to evaluate hepatitis B virus (HBV) infection in an urban population. This longitudinal study was conducted in Bamako District and Kati Commune. After a preparatory phase, the persons who accepted the protocol were assessed for HBsAg. HBsAg carriers had blood collection for HBeAg assay, viral load assessment, genotyping, DNA mutation testing, and severity of hepatic fibrosis and necrosis. At the end of this study, 1475 persons were included, of which 195 had HBsAg positive confirmed, that is to say 13.97%. The mean age of HBsAg positive patients was 35.11 ± 11.12 years with a sex ratio of 2.68. HBeAg was found in 8.9% of the patients tested for this antigen. The viral load was undetectable in 10.52% of patients and greater than 2000 IU/mL in 32.24% of cases. Fibrosis ≥ F2 and necrosis ≥ A2 were found in respectively 19.72% and 6.80% of cases. Genotype E was found in 91.6 patients and an R249S mutation observed in 39.04% of cases. Conclusion: HBV infection has a serious impact on socio-economic development in Mali because it affects mainly the young male population, hence the need to organize preventive measures effectively.

Endovascular Repair of Abdominal Aortic Aneurysm May Not Provide Long-Term Survival Benefit  [PDF]
R. Englund, N. Katib
Surgical Science (SS) , 2016, DOI: 10.4236/ss.2016.77045
Abstract: Purpose: To investigate the long term survival benefit for the treatment of abdominal aortic aneurysmal (AAA) disease with Endovascular Aneurysm Repair (EVAR). Our hypothesis is that patients undergoing EVAR have an equivalent survival to an age matched population. Methods: Between 1997 and 2014 all patients treated for an AAA with EVAR by a single surgeon were prospectively followed and at 12 monthly intervals ultrasonography was utilised to assess the size of the aorta after treatment. Data from the Births, Deaths and Marriages was also collected regarding the survival of these patients. As of 2003 all patients with AAA were treated electively with EVAR. Results: There were a total of 145 patients treated with EVAR for AAA during the study period, 143 who survived the 30-day post-operative period. The long-term survival following EVAR at one year was 95% (95% C.I.: 88% to 97%), at 5 years 56% (95% C.I.: 42% to 64%), and at 10 years 28% (95% C.I.: 17% to 42%). Compared to an age-matched population the EVAR group had a lower than expected long term survival (P < 0.0001). Discussion: EVAR for the treatment of abdominal aortic aneurysms can be achieved with acceptable 30 day survival and freedom from aneurysm related death. However selection of patients for EVAR may significantly effect long-term survival if patients are fit for EVAR but not open operation. The question arises as to whether EVAR should be performed in patients with questionable long-term survival, even if they are fit for this procedure.
