Percutaneous treatment of <i>de novo</i>unprotected left main stenosis in unselected consecutive patients: Experience of a high volume center

引用

World Journal of Cardiovascular Diseases 2013年第7期3卷 419-427页

Background: Percutaneous coronary intervention (PCI) has been increasingly employed to treat unprotected left main (ULM) stenosis, with hard endpoints similar to by-pass surgery, in patients selected by a Heart Team. Methods: From January 2008 to December 2011, 317 unselected and consecutive patients with de novo ULM stenosis underwent PCI with both bare metal (BMS) and drug-eluting (DES) stents. Major adverse cardiovascular events, target lesion (TLR) and vessel (TVR) revascularization were evaluated over a mean period of 590 ± 371 days. Results: Our population was characterized by a mean age 72 ± 10 years, high rate of acute coronary syndrome (ACS) (either with ST or non-ST elevation myocardial infarction, 15.5% and 35% respectively), severe comorbidity 16%, mean Euroscore 7 ± 3, mean Syntax Score 25 ± 9. In-hospital mortality was 6%. During the follow-up period, all-cause mortality was 16.7%, falling to 7% at the end of the follow-up, excluding patients presenting with ACS. TLR was observed and treated in 15% of patients. BMS utilization, age >75 years, ACS indication, Syntax Score >32 and associated peripheral artery disease were independent predictors of mortality at multivariate analysis. Conclusions: Stenting of ULM stenosis appears to be associated with a favorable mid-term outcome, even in an unselected population.

Evaluation of Condom Use among University Undergraduates in Port Harcourt, Nigeria

引用

Journal of Biosciences and Medicines 2020年第5期8卷 31-41页

作者： Emmanuel Okwudili Oranu Prince Atochi Woruka Esther Nonye-Enyindah Department of Obstetrics and Gynaecology University of Port Harcourt Teaching Hospital Port Harcourt Nigeria Department of Obstetrics and Gynaecology Rivers State University Teaching Hospital Port Harcourt Nigeria

Background: Barrier contraception has the beauty of dual protection—against pregnancy and sexually transmitted infections. Following the persisting burden of unsafe abortion and human immunodeficiency virus (HIV), much sensitization/campaign has been ongoing in the past few decades by government and non-governmental organisations (NGOs) in Nigeria against unprotected sexual intercourse. The youth are generally assumed to have high risk sexual behaviour, hence this study on Port Harcourt university undergraduates. Objectives: To determine the awareness and use of condom among University undergraduates in Port Harcourt. Methods: The study was a prospective descriptive cross-sectional study of 636 undergraduate students of the University of Port Harcourt and Rivers state University, South-south Nigeria. The multistage sampling technique was used to randomly select participants and data collected using a pretested structured self administered questionnaire. Data was analyzed using version 23.0 SPSS and reported in means, frequencies and percentages. Probability value was set at 5% (p χ2 = 200.602). Only 5.5% of the respondents in this study were willing to know their HIV status. Conclusion: There is a high level of condom awareness among Port Harcourt University undergraduates. Surprisingly, their practice of unprotected sexual intercourse is still high.

Plant Species Composition and Distribution in Relation to Land Use Patterns in Serengeti Ecosystem Tanzania

引用

Open Journal of Forestry 2015年第6期5卷 607-620页

作者： Cosmas Mligo Department of Botany University of Dar es Salaam Dar es Salaam Tanzania

Serengeti is the largest ecosystem in Tanzania endowed with high level of biodiversity in protected and unprotected areas. Serengeti National Park is the only protected area in a matrix of unprotected areas characterized with a wide range of human activities which threaten biodiversity conservation. It was assessed plant species composition, diversity, distribution and vegetation structure in both the protected and unprotected areas of the ecosystem. Two transects with twenty plots each were established in each vegetation type in which data was collected. A significantly higher species composition (262) and diversity (2.39 ± 0.03) was observed in unprotected areas than in the protected area (163 and 2.06 ± 0.04 respectively). The DCA ordination of the species data from the two management regimes formed four clusters based on similarity in plant species composition, where three clusters were from unprotected areas and one from protected area. The variations in plant species composition ranged from 35.69% to 65.92% for the first four DCA axes. There was no significant difference in stem density between protected and unprotected areas of the ecosystem. Although high density of trees at 10 - 14 cm DBH sizes was observed in both sides of the conservation management regimes, individuals with DBH above 65 cm existed in the protected area but were absent in unprotected areas. It can be concluded that the decrease of plant species diversity and density in unprotected area is because of habitat degradation associated with exploitation pressure, livestock grazing and other forms of disturbance related with anthropogenic activities. Because of high demand for plant resources, the local community needs to establish woodlots to cater for wood resource needs outside the protected areas of Serengeti. Also, pastoralists need to diversify livestock keeping systems compatible with limited grazing land in unprotected area of the Serengeti ecosystem.
