RESUMENLa evolución morfosedimentaria de la playa de sa Ràpita (Sur de Mallorca) se ha visto afectada a partir de la construcción, en 1977, del puerto deportivo ubicado en su extremo NO. La consecuencia más importante ha sido la modificación de la deriva litoral, ya que el puerto actúa como trampa sedimentaria. Este hecho impide que el sedimento pueda distribuirse a lo largo de la playa, como ocurría antes de su construcción. La playa ha sufrido procesos erosivos importantes a partir de 1977 hasta la actualidad. Así, a partir de esa fecha, el sector más próximo al puerto deportivo ha aumentado su superficie con una media de 0.5 m/a, mientras que el resto de la playa se erosiona con una media de entre -0.19 y -0.34 m/a. El estudio se ha realizado con la ayuda de un Sistema de Información Geográfica y con la herramienta Digital Shoreline Analysis System, que permite cuantificar los procesos erosivos a lo largo de un periodo comprendido entre los años 1956 y 2012.Palabras clave: Mallorca; sa Ràpita; deriva litoral; erosión; GIS; DSAS.

Background Diabetes mellitus predicts poorer outcomes in patients with acute coronary syndrome (ACS), but the magnitude of this association in patients at older ages remains controversial. Methods Data were extracted from the Codi Infart database. All consecutive patients with diagnosis of ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) between 2010 and 2015 were included. We assessed the impact of diabetes mellitus on 30-day and one-year mortality in patients aged less than and at least 75 years. Results A total of 12 792 cases were registered, of whom 3023 (23.6%) were aged at least 75 years. About 20% patients had previous diabetes mellitus diagnosis. Patients aged at least 75 years had higher prevalence of comorbidities, higher proportion of heart failure at admission, a more extensive coronary artery disease and significant delay to reperfusion (P < 0.001). Diabetes mellitus was associated with higher 30-day mortality both in young [odds ratio (OR) 1.97, 95% confidence interval (CI): 1.43–2.70] and in elderly patients (OR 1.43, 95% CI: 1.07–1.91). After adjusting for potential confounders, this association remained significant in young patients (OR 1.47, 95% CI: 1.00–2.16, P = 0.047), but not in the elderly (OR 1.14, P = 0.43). Likewise, a crude association between diabetes mellitus and one-year mortality was observed in both groups (young patients: HR = 1.93; 95% CI: 1.51–2.46; older patients: HR = 1.33; 95% CI: 1.08–1.64). However, after adjusting for potential confounders, this association remained significant in younger patients (HR = 1.46; 95% CI: 1.13–1.89; P < 0.001), but not in the elderly (HR = 1.16; P = 0.17). Conclusion A significant proportion of these nonselected patients with STEMI had previous diabetes mellitus. The association between diabetes mellitus and outcomes is different according to age.
