El diagnóstico ambiental en obras constructivas de cayo Cruz: premisa para implementar acciones de capacitación / The environmental diagnosis in construction cayo Cruz: premise to implement training actions

El objetivo del artículo es proponer un diagnóstico ambiental en zonas de desarrollo constructivo de cayo Cruz para la capacitación ambiental de los técnicos de la Asociación Económica Internacional Unión de Construcciones Militares Bouygues Bâtiment International en acciones preventivas de conservación. Para ello, se aplicó el diagnóstico en el área de intervención, se emplearon métodos como el analítico-sintético y el enfoque de sistema en la elaboración de las acciones y la estructuración de sus fundamentos teóricos. El análisis documental, la observación y el diagnóstico ambiental permitieron corroborar el estado actual y dinámica de los componentes del medio, así como las necesidades de capacitación ambiental de los técnicos de la AEI UCM– BBI. Se capacitaron 30 técnicos en la conservación de los componentes naturales y paisajísticos afectados por las parcelas de desarrollo turístico.The objective of the article is to propose an environmental diagnosis in areas of constructive development of Cruz Bay for the environmental training of technicians of the International Economic Association Union of Military Constructions Bouygues Bâtiment International in preventive conservation actions. To do this, the diagnosis was applied in the intervention area, using methods such as analytical-synthetic and system approach in the development of actions and the structuring of their theoretical foundations. The documentary analysis, observation and environmental diagnosis made it possible to corroborate the current and dynamic state of the environmental components, as well as the environmental training needs of the AEI UCM-BBI technicians. 30 technicians were trained in the conservation of the natural and landscape components affected by the plots of tourist development

Contemporary use of cefazolin for MSSA infective endocarditis: analysis of a national prospective cohort

Objectives: This study aimed to assess the real use of cefazolin for methicillin-susceptible Staphylococcus aureus (MSSA) infective endocarditis (IE) in the Spanish National Endocarditis Database (GAMES) and to compare it with antistaphylococcal penicillin (ASP). Methods: Prospective cohort study with retrospective analysis of a cohort of MSSA IE treated with cloxacillin and/or cefazolin. Outcomes assessed were relapse; intra-hospital, overall, and endocarditis-related mortality; and adverse events. Risk of renal toxicity with each treatment was evaluated separately. Results: We included 631 IE episodes caused by MSSA treated with cloxacillin and/or cefazolin. Antibiotic treatment was cloxacillin, cefazolin, or both in 537 (85%), 57 (9%), and 37 (6%) episodes, respectively. Patients treated with cefazolin had significantly higher rates of comorbidities (median Charlson Index 7, P <0.01) and previous renal failure (57.9%, P <0.01). Patients treated with cloxacillin presented higher rates of septic shock (25%, P = 0.033) and new-onset or worsening renal failure (47.3%, P = 0.024) with significantly higher rates of in-hospital mortality (38.5%, P = 0.017). One-year IE-related mortality and rate of relapses were similar between treatment groups. None of the treatments were identified as risk or protective factors. Conclusion: Our results suggest that cefazolin is a valuable option for the treatment of MSSA IE, without differences in 1-year mortality or relapses compared with cloxacillin, and might be considered equally effective
