    The energy transition relies heavily on minerals such as copper and lithium. In today's modern world, where consumers are increasingly aware of the need to protect tomorrow's natural resources, mining is expected to be not only economical but also socially and environmentally sustainable. In light of this, mining production must be competitive in these three dimensions of sustainability to meet demand, understanding that consumers will prefer a more sustainable material. This study aims to comprehend the competitiveness of copper and lithium Chilean production from a sustainable perspective using a SWOT analysis (Strengths, Weaknesses, Opportunities, and Threats) developed by a panel of experts.Based on an analysis of 165 factors driving mining's sustainability, the copper industry in Chile ranks third in the sustainability ranking for the world, while lithium ranks second. The foregoing implies that Chile, the world's leading producer of copper and second global producer of lithium, still has room to improve sustainability by introducing the following measures: (1) improving effective communication among stakeholders; (2) dissemi-nating sustainability knowledge; (3) developing State mining policies; (4) restoring stability in the country; (5) developing a sustainable quality brand of Chilean commodities; and (6) capitalizing on valuable human capital.

    Background: Guidelines for the management of unstable angina (UA) and non ST elevation myocardial infarction (NSTEMI) have been issued, however current practices are unknown in Chile. Aim: To evaluate in a prospective cohort of NSTEMI patients the current practices, treatments and risk factors. Material and Methods: One year prospective International non interventional registry, conducted in Chile between January 2005 and November 2006. Results: Two hundred thirty three Chilean NSTEMI patients were enrolled. Mortality was 5.5% at the end of the follow-up. Mean age was 61.6 years, and 30.6% were female. Most of the patients had at least one risk factor (98%): hypertension (84%), previous myocardial infarction (33%), dyslipidemia (54%), diabetes (33%), current smoking (30%). Main procedures during the hospitalization were coronary angiogram (67%), angioplasty (33%; 88% with stent) and coronary bypass surgery (7%). During procedures, 31% of patients received clopidogrel, and 4.2% glycoprotein IIb/IIIa antagonists. Medical management was selected for 60% of patients. In comparison to men, women received less interventional procedures despite having more risk factors. Treatments prescribed at discharge were aspirin (97%), clopidogrel (49%), beta blockers (78%), diuretics (21%), lipid lowering agents (78%), oral hypoglycemic agents (13%) and insulin (9%). At the end of the 1-year follow-up, treatments were aspirin (84%), beta blockers (72%), diuretics (19%), and dual antiplatelet therapy with clopidogrel (16%). Conclusions: A high prevalence of multiple risk factors for cardiovascular disease in Chilean patients with NSTEMI was observed. More aggressive primary and secondary preventive measures are urgently needed. Use of therapies proposed in the guidelines is high, but dual antiplatelet therapy is less than 50% at discharge and decreases during the one year-follow-up. (Rev Med Chile 2011; 139: 19-26).
