Lipid profiles of patients presenting with acute myocardial infarction in a South African regional hospital

Background: Cardiovascular disease is an important cause of morbidity and mortality in South Africa and hyperlipidaemia is a major contributing modifiable risk factor.Objectives: To describe the lipid profiles of patients with acute myocardial infarction and to compare values with recommended target levels outlined in the South African Dyslipidaemia Guideline Consensus Statement.Methods: We performed a retrospective chart review of patients admitted with a diagnosis of acute myocardial infarction to a regional hospital in Durban, South Africa, between 1 January and 31 December 2016. Patients had a non-fasting lipogram taken within the first 24 hours of admission.Results: We enrolled 126 subjects. The mean age was 57.6 (SD ± 9.4) years. One hundred and ten subjects (87.3%) met criteria for hyperlipidaemia. Previous statintherapy was associated with lower LDL-cholesterol values (3.43mmol/L vs. 4.03mmol/L, p=0.02), but only 9 (11.2%) of the 80 subjects on therapy (88.8%) fell below the levels recommended for their risk category by the South African Dyslipidaemia Guideline Consensus Statement. Overall, 23 subjects (18.3% of the entire study group) demonstrated LDL-C values at presentation that were below the recommended values.Conclusions: A high proportion of subjects presenting with acute myocardial infarction show evidence of suboptimal control of pre-existing hyperlipidaemia

ABSTRACT INTRODUCTION Major advantages of polymer electrolyte membrane fuel cells are operation at relatively low temperature and system robustness. Low temperature operation allows them to start quickly (less warm-up time) and results in less wear on system components, resulting in better durability. However, a noble-metal catalyst (typically platinum) is to be used to separate the hydrogen's electrons and protons, adding to system cost. PEM fuel cells are used primarily for transportation applications and some stationary application

Advanced separation technology for flue gas cleanup. Final report, February 1998

The objective of this work by SRI International was to develop a novel system for regenerable SO{sub 2} and NO{sub x} scrubbing of flue gas that focuses on (1) a novel method for regenerating spent SO{sub 2} scrubbing liquor and (2) novel chemistry for reversible absorption of NO{sub x}. High efficiency, hollow fiber contactors (HFCs) were proposed as the devices for scrubbing the SO{sub 2} and NO{sub x} from the flue gas. The system would be designed to remove more than 95% of the SO{sub 2} and more than 75% of the NO{sub x} from flue gases typical of pulverized coal-fired power plants at a cost that is at least 20% less than combined wet limestone scrubbing of SO{sub x} and selective catalytic reduction of NO{sub x}. In addition, the process would generate only marketable by-products, if any (no waste streams are anticipated). The major cost item in existing technology is capital investment. Therefore, the approach was to reduce the capital cost by using high-efficiency, hollow fiber devices for absorbing and desorbing the SO{sub 2} and NO{sub x}. The authors also introduced new process chemistry to minimize traditionally well-known problems with SO{sub 2} and NO{sub x} absorption and desorption. The process and progress in its development are described
