Reflexiones de estudiantes universitarios, docentes de Agroecología (U.N.Cuyo) y agentes de extensión del INTA en prácticas de intervención socioproductivas en las zonas de Luján de Cuyo y Valle de Uco, Mendoza

En el marco de la asignatura Agroecología y Ambientes Rurales de la carrera en Ingeniería en Recursos Naturales Renovables (FCA- UNCuyo), se han realizado durante 10 años académicos consecutivos, dos actividades consistentes en visitar a diferentes tipos sociales agrarios ubicados en Luján de Cuyo y el Valle de Uco. En las nombradas actividades, los estudiantes realizan una visita extendida a productores que integran diferentes cadenas productivas, con el objetivo de caracterizar el ecosistema, sociosistema y tecnosistema en cada caso, además de diferenciar manejos convencionales y agroecológicos. Con la información recabada y reflexionada, los estudiantes realizan un trabajo integrador, con carácter de condición obligatoria para rendir el examen final de la asignatura, que rescata una problemática detectada y propone una solución socio tecnológica con base agroecológica, ajustada a las características de tipo social agrario abordado. El nombrado material queda a disposición de los actores involucrados para ser utilizado como una herramienta de comprensión de la dinámica socio-productiva y territorial. En el presente relato realizamos una breve síntesis sobre las experiencias de cada visita a campo y se presentan las reflexiones de los actores involucrados acerca de esta experiencia.In the framework of agroecology and rural environments race course in Engineering in Renewable Natural Resources (FCA UNCuyo) were performed for 10 consecutive school years, two consistent activities visit different agricultural social types are located in Lujan de Cuyo and Uco Valley. In the named activities, students made an extended visit to producers that integrate different production chains, in order to characterize the ecosystem, sociosistema and Technosystem in each case, in addition to conventional agro differentiate and handling. With the information gathered and reflected, students take an integrative work, as an obligatory condition to take the final exam of the subject, who rescues a detected problem and proposes a solution partner agroecologically technological basis and adjusted to the characteristics of a social nature agricultural addressed.

Effect of a quality improvement program on compliance to the sepsis bundle in non-ICU patients: a multicenter prospective before and after cohort study

ObjectiveSepsis and septic shock are major challenges and economic burdens to healthcare, impacting millions of people globally and representing significant causes of mortality. Recently, a large number of quality improvement programs focused on sepsis resuscitation bundles have been instituted worldwide. These educational initiatives have been shown to be associated with improvements in clinical outcomes. We aimed to evaluate the impact of a multi-faceted quality implementing program (QIP) on the compliance of a “simplified 1-h bundle” (Sepsis 6) and hospital mortality of severe sepsis and septic shock patients out of the intensive care unit (ICU).MethodsEmergency departments (EDs) and medical wards (MWs) of 12 academic and non-academic hospitals in the Lombardy region (Northern Italy) were involved in a multi-faceted QIP, which included educational and organizational interventions. Patients with a clinical diagnosis of severe sepsis or septic shock according to the Sepsis-2 criteria were enrolled in two different periods: from May 2011 to November 2011 (before-QIP cohort) and from August 2012 to June 2013 (after-QIP cohort).Measurements and main resultsThe effect of QIP on bundle compliance and hospital mortality was evaluated in a before–after analysis. We enrolled 467 patients in the before-QIP group and 656 in the after-QIP group. At the time of enrollment, septic shock was diagnosed in 50% of patients, similarly between the two periods. In the after-QIP group, we observed increased compliance to the “simplified rapid (1 h) intervention bundle” (the Sepsis 6 bundle – S6) at three time-points evaluated (1 h, 13.7 to 18.7%, p = 0.018, 3 h, 37.1 to 48.0%, p = 0.013, overall study period, 46.2 to 57.9%, p < 0.001). We then analyzed compliance with S6 and hospital mortality in the before- and after-QIP periods, stratifying the two patients’ cohorts by admission characteristics. Adherence to the S6 bundle was increased in patients with severe sepsis in the absence of shock, in patients with serum lactate <4.0 mmol/L, and in patients with hypotension at the time of enrollment, regardless of the type of admission (from EDs or MWs). Subsequently, in an observational analysis, we also investigated the relation between bundle compliance and hospital mortality by logistic regression. In the after-QIP cohort, we observed a lower in-hospital mortality than that observed in the before-QIP cohort. This finding was reported in subgroups where a higher adherence to the S6 bundle in the after-QIP period was found. After adjustment for confounders, the QIP appeared to be independently associated with a significant improvement in hospital mortality. Among the single S6 procedures applied within the first hour of sepsis diagnosis, compliance with blood culture and antibiotic therapy appeared significantly associated with reduced in-hospital mortality.ConclusionA multi-faceted QIP aimed at promoting an early simplified bundle of care for the management of septic patients out of the ICU was associated with improved compliance with sepsis bundles and lower in-hospital mortality

Fusion of multispectral and LIDAR remote sensing data for the estimation of forest attributes in an Alpine region

This paper presents an analysis on the integration of airborne LIDAR and satellite multispectral data (IRS 1C LISS) for the prediction of forest stem volume at plot level. A set of variables has been extracted from both LIDAR and multispectral data and some models have been defined considering data source (LIDAR, multispectral and a combination of both) and the species composition of the plot areas. The analyzed data set comprises 799 ground-truth plots within the forested areas of the Trento Province, Italy (about 3 000 km²), in the Italian Alps. This area is characterized by a large heterogeneity in terms of ecological environments, species composition, morphology, and altitude. Experimental results show that the combination of LIDAR and IRS 1C LISS data for the estimation of forest attributes is effective. The best model developed comprises variables extracted from both these dataset, even if variables derived from LIDAR data provide the most important contribution
