Caracterización de la vegetación en los ambientes ribereños del curso medio del río Ulla

La vegetación natural de las riberas fluviales se ordena en bandas paralelas al cauce del río hasta tomar contacto con la vegetación climácica de las laderas. Esta distribución es el resultado de la interacción de factores muy diversos como el balance de humedad edáfica, la acción geomorfológica de las aguas o la naturaleza del sustrato, cuya intensidad se modifica gradualmente a medida que se incrementa la distancia con el río. En el curso medio del valle del Ulla (A Coruña-Pontevedra) se han reconocido cuatro ambientes ecológicos principales que se corresponden con tipos de vegetación diferentes: ambientes acuáticos permanentes, riberas de acumulación, riberas de erosión y riberas estabilizadas, aunque existiendo muchas formas de transición debido al fuerte dinamismo de estos medios. En todos ellos se observó un elevado grado de alteración quedando reducida la vegetación ribereña a estrechas bandas longitudinales como consecuencia del fuerte impacto humano. The natural vegetation of the river banks orders itself in parallel bands to the river until taking contact with the climatic vegetation of the slopes. This distribution is the result of the interaction of diverse factors, like the soils humidity balance, the geomorphological action of water or the nature of the substrate, whose intensity is modified gradually as the distance with the river is increased. In the middle course of the valley of the Ulla river (Galicia, Spain), four main ecological environments have been recognized, that correspond with different types of vegetation: permanent aquatic environments, accumulation banks, erosion banks and stabilized banks. Although there are many forms of transition due to the dynamism of these environments. In all of them, we observed a high degree of alteration. The vegetation of the borders of the river is being reduced to a narrow longitudinal bands as a result of the strong human impact

Role of age and comorbidities in mortality of patients with infective endocarditis

[Purpose]: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. [Methods]: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. [Results]: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39–1.88),and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. [Conclusion]: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group
