Stroke in Indigenous Africans, African Americans, and European Americans: Interplay of Racial and Geographic Factors.

Abstract: Background and Purpose— The relative contributions of racial and geographic factors to higher risk of stroke in people of African ancestry have not been unraveled. We compared stroke type and contributions of vascular risk factors among indigenous Africans (IA), African Americans (AA), and European Americans (EA). Methods— SIREN (Stroke Investigative Research and Educational Network) is a large multinational case–control study in West Africa—the ancestral home of 71% AA—whereas REGARDS (Reasons for Geographic and Racial Differences in Stroke) is a cohort study including AA and EA in the United States. Using harmonized assessments and standard definitions, we compared data on stroke type and established risk factors for stroke in acute stroke cases aged ≥55 years in both studies. Results— There were 811 IA, 452 AA, and 665 EA stroke subjects, with mean age of 68.0±9.3, 73.0±8.3, and 76.0±8.3 years, respectively ( P <0.0001). Hemorrhagic stroke was more frequent among IA (27%) compared with AA (8%) and EA (5.4%; P <0.001). Lacunar strokes were more prevalent in IA (47.1%), followed by AA (35.1%) and then EA (21.0%; P <0.0001). The frequency of hypertension in decreasing order was IA (92.8%), followed by AA (82.5%) and then EA (64.2%; P <0.0001) and similarly for diabetes mellitus IA (38.3%), AA (36.8%), and EA (21.0%; P <0.0001). Premorbid sedentary lifestyle was similar in AA (37.7%) and EA (34.0%) but lower frequency in IA (8.0%). Conclusions— Environmental risk factors such as sedentary lifestyle may contribute to the higher proportion of ischemic stroke in AA compared with IA, whereas racial factors may contribute to the higher proportion of hypertension and diabetes mellitus among stroke subjects of African ancestry.

Removal of Remazol Brilliant Violet-5R dye using periwinkle shells

Abstract: The purpose of this research is to obtain optimal processing conditions for the adsorption of Remazol Brilliant Violet-5R (RBV-5R) dye onto activated carbon prepared from periwinkle shells (PSAC) by chemical activation with KOH using response surface methodology. Central composite design (CCD) was used to determine the effects of three preparation variables; CO2 activation temperature, CO2 activation time and KOH:char impregnation ratio (IR) on two responses; percentage RBV-5R dye removal and PSAC yield. Based on the CCD, two quadratic models were developed for percentage RBV-5R dye removal and PSAC yield, respectively. The most influential factor on each experimental design response was identified from the analysis of variance (ANOVA). The optimum conditions for the adsorption of RBV-5R dye onto PSAC were CO2 activation temperature of 811 °C, CO2 activation time of 1.70 h and IR of 3.0, resulting in 81.28% RBV-5R dye removal and 28.18% PSAC yield. PSAC prepared under optimum conditions was mesoporous wit...

Gastroesophageal reflux disease and etiological correlates among Nigerian adults at Ogbomoso

Abstract: Background: Gastroesophageal reflux disease is a common disorder globally but the prevalence and severity of symptoms and complications do have ethnic and geographic variations. Aim: The aim of the study was to determine the prevalence of gastroesophageal reflux disease (GERD) among adults in Ogbomoso, Southwest Nigeria, and the risk factors associated with it. Methodology: The study was a hospital-based descriptive cross-sectional survey. The study population consisted of consenting male and female adults aged 18 to 87 years recruited from the outpatient departments of three health institutions in Ogbomoso, Oyo State, Nigeria. A predesigned questionnaire consisting of GerdQ and other relevant information was administered to the participants. Results: A total of 772 subjects were interviewed. The prevalence of GERD was 9.3% among the subjects. There was a significant association between increasing age and GERD. Other risk factors considered showed no significant association with the disease. Conclusion: GERD has a moderate prevalence among adults in Ogbomoso, Southwest Nigeria and there is a significant association between increasing age and GERD.
