BACKGROUND The numbers of people attending emergency departments (EDs) at hospitals are increasing. We aimed to analyse trends in ED attendance at a Swiss university hospital between 2002 and 2012, focussing on age-related differences and hospital admission criteria. METHODS We used hospital administrative data for all patients aged ≥16 years who attended the ED (n=298,306) at this university hospital between 1 January 2002, and 31 December 2012. We descriptively analysed the numbers of ED visits according to the admission year and stratified by age (≥65 vs <65 years). RESULTS People attending the ED were on average 46.6 years old (standard deviation 20 years, maximum range 16‒99 years). The annual number of ED attendances grew by n=6,639 (27.6%) from 24,080 in 2002 to 30,719 in 2012. In the subgroup of patients aged ≥65 the relative increase was 42.3%, which is significantly higher (Pearson's χ2=350.046, df=10; p=0.000) than the relative increase of 23.4% among patients<65 years. The subgroup of patients≥65 years attended the ED more often because of diseases (n=56,307; 85%) than accidents (n=9,844; 14.9%). This subgroup (patients≥65 years) was also more often admitted to hospital (Pearson's χ2=23,377.190; df=1; p=0.000) than patients<65 years. CONCLUSIONS ED attendance of patients≥65 years increased in absolute and relative terms. The study findings suggest that staff of this ED may want to assess the needs of patients≥65 years and, if necessary, adjust the services (e.g., adapted triage scales, adapted geriatric screenings, and adapted hospital admission criteria).

Following the extreme low ice year of 2007, primary production and the sinking export of particulate and gel-like organic material, using short-term particle interceptor traps deployed at 100 m, were measured in the southeastern Beaufort Sea during summer 2008. The combined influence of early ice retreat and coastal upwelling contributed to exceptionally high primary production (500 ± 312 mg C/m**2/day, n = 7), dominated by large cells (>5 µm, 73% ± 15%, n = 7). However, except for one station located north of Cape Bathurst, the sinking export of particulate organic carbon (POC) was relatively low (range: 38-104 mg C/m**2/day, n = 12) compared to other productive Arctic shelves. Estimates indicate that 80% ± 20% of the primary production was cycled through large copepods or the microbial food web. Exopolymeric substances were abundant in the sinking material but did not appear to accelerate POC sinking export. The use of isotopic signatures (d13C, d15N) and carbon/nitrogen ratios to identify sources of the sinking material was successful only at two stations with a strong marine or terrestrial signature, indicating the limitations of this approach in hydrographically and biologically complex Arctic coastal waters such as in the Beaufort Sea. At these two stations influenced by either coastal upwelling or erosion, the composition and magnitude of particulate sinking fluxes were markedly different from other stations visited during the study. These observations underscore the fundamental role of mesoscale circulation patterns and hydrodynamic singularities on the export of particulate organic material on Arctic shelves.

Se ha estudiado la composición de las poblaciones de crustáceos decápodos en los fondos detríticos circalitorales del Este y Sureste ibérico, con relación a sus diferentes facies, efectuándose diferentes análisis estadísticos sobre la composición y diversidad. La taxocenosis de crustáceos decápodos muestra elevados valores de abundancia, riqueza y diversidad en las localidades identificadas como fondos detríticos costeros de aspecto típico. Por último, algunos grupos de especies podrían ser utilizados para caracterizar las biocenosis típica de fondos detríticos costeros, tales como: Paguristes eremita, Ebalia edwardsi, E. deshayesi, Eurynome aspera, Galathea intermedia, Parthenope massena, y Anapagurus hyndmani; la biocenosis del detrítico costero enfangada: Ebalia tuberosa, Atelecyclus rotundatus, Ethusa mascarone, y Liocarcinus zariquieyi; y la biocenosis de arenas fangosas: Upogebia deltaura, Goneplax rhomboides.

During the austral summer of 2005, the Weddell deep sea and adjacent basins were sampled in the course of the ANDEEP III project. In this study, 19 epibenthic-sledge stations are analyzed, with a focus on species diversity and distribution patterns of polychaetes. The polychaete fauna of the deep Southern Ocean has been found to be similarly speciose and diverse compared with deep-sea basins worldwide. Also, in depths below 2,000 m many polychaete species do not seem to be endemic for certain areas but are rather far spread within the Southern Ocean and beyond. Therefore, ongoing faunal exchanges between adjacent basins, even beyond the Antarctic convergence, are strongly suggested, ruling out a general isolation of the Southern Ocean deep-sea benthos. Driving forces behind species distribution patterns were investigated. The findings indicate that polychaete species' distribution in the Southern Ocean deep sea is rather dependent on local environment than depths.
