Analysis of socio-economic impact of Konkola Copper Mine (KCM) on the mining community in Zambia : a case study of Chingola Town

2008

This thesis focuses on the impact of Konkola Copper Mine (KCM). This company is a Multinational Mining Corporation. It is based in Chingola town in Zambia. The study seeks to establish whether the Mining company is contributing to the development of the town or not. It also examines the development agreements which the company entered into with government and show how this commitment has affected the company’s contributions to the local community. Specifically, the study seeks to critically examine the development agreements with a view to establishing whether these agreements emphasized strict observance of corporate social responsibilities or not The methodological approach used in this s…

Kyrieleis’ vasculitis in acute retinal necrosis

2010

We report the first case in the literature of Kyrieleis' vasculitis related to acute retinal necrosis by Varicella zoster virus in a 76-year-old woman with bilateral involvement. In our patient the arterial lesions appeared 15 days after the initial presentation.

Early and midterm outcomes of bioresorbable vascular scaffolds for ostial coronary lesions: insights from the GHOST-EU registry.

2016

Aims: We aimed to investigate the outcomes of bioresorbable vascular scaffolds (BVS) in coronary ostial lesions. Ostial lesions represent a challenging angiographic subset, with higher event rates compared with non-ostial lesions. BVS might be associated with advantages over the long term, but their safety in this setting remains to be explored. Methods and results: Procedural and 12-month follow-up data from consecutive patients treated with BVS for lesions located at the ostium of the right (RCA), left anterior (LAD) or circumflex (LCX) coronary in 11 European centres were collected. The primary device-oriented endpoint was defined as a combination of cardiovascular death, target vessel m…

The primary device-oriented endpoint was defined as a combination of cardiovascular death target vessel myocardial infarction or target lesion revascularisation. The database included a total of 1549 lesions in 1304 patients with a mean age of 62 +/- 11years. There were 90 ostial lesions (5.8%) in 84 patients (6.4%) located at the ostial RCA (14; 16%) LCX (29; 32%) or LAD (47; 52%). Patients presenting with ostial lesions did not differ from the remaining cohort except for a higher incidence of prior revascularisation. Predilation was performed in 97% of the lesions (vs. 96% in non-ostial p= 0.618) post-dilation in 43% (versus 58% in the non-ostial group p= 0.008). At quantitative coronary angiography treatment of ostial lesions was associated with higher residual stenosis (30% [23-41] vs. 26% [20-37] p= 0.035) but no difference in minimum lumen diameter existed (p= 0.447). Follow-up data were available at 385 [362-465] days. The 12-month Kaplan-Meier estimated rates of scaffold thrombosis were 4.9% and 2.0% (ostial and non-ostial lesion groups respectively log-rank p= 0.005). The device-oriented composite endpoint occurred respectively in 12.6% and 4.6% at 12 months (log-rank p= 0.001). Treatment of ostial lesions was an independent predictor of this endpoint (p= 0.0025 HR 2.65 [1.41-4.97]).OstiumAims: We aimed to investigate the outcomes of bioresorbable vascular scaffolds (BVS) in coronary ostial lesions.
