Medicosocial outcome after admission in post-intensive care unit at PRM St-Hélier, Rennes

IntroductionPost-Intensive Care Units (PICU) are PRM structures aiming to start the appropriated rehabilitative care as early as possible even though persistent complex medical issues.ObjectiveTo assess medicosocial outcomes of patients away from their admission in PICU.MethodsA retrospective descriptive study that included 81 consecutive patients (mean age 51 years) admitted from 2008 to 2012 in the PICU of Pôle St-Helier Rennes based on called semi-structured interviews between March 2014 and March 2015. Exhaustive data (only 4 lost, 5%) by the patient himself and/or a member of family on autonomy, place of life, structures since the release and reintegration, of patients for 85% of them brain damaged.ResultsThere is 29% (21/77) of death (post-exit life: 1,6 years±1.18). Eighty percent live at home (46/56) of which only 5 without family environment, 10% (5/56) in medicosocial structures (foster or nursing homes…), 10% in hospital (hospital at home, persistent vegetative units…). Fourteen percent (8/56) are completely autonomous and work, all with adaptations. Twenty-three percent (13/56) had a significant dependence for activities of daily life and instrumental ones. Forty percent (22/56) have no hobby. Use of different downstream structures, long-term readaptative monitoring, legal and families’ feelings were also analyzed.Discussion and ConclusionMedical and social outcome of patients in the aftermath of a stay in PICU is disparate, depending on the pathology involved, but also the pre-social situation that seems to be the main predictor of returning home. Most patients have regained a relatively large autonomy for the daily life activities but are embarrassed to complex instrumental activities impeding social inclusion. These results are consistent with those of the literature on head trauma patients but no other study has focused for the moment on the specific population of patients admitted to the PICU. We see the value of such early rehabilitative care units with a real impact on the subsequent independence and opportunities back home

Spatial and temporal variability in coccolithophore abundance and distribution in the NW Iberian coastal upwelling system

A systematic investigation of the spatial and temporal variability in coccolithophore abundance and distribution through the water column of the NW Iberian coastal up-welling system was performed. From July 2011 to June 2012, monthly sampling at various water depths was conducted at two parallel stations located at 42 degrees N. Total coccosphere abundance was higher at the outer-shelf station, where warmer, nutrient-depleted waters favoured coccolithophore rather than phytoplanktonic diatom blooms, which are known to dominate the inner-shelf location. In seasonal terms, higher coccosphere and coccolith abundances were registered at both stations during upwelling seasons, coinciding with high irradiance levels. This was typically in conjunction with stratified, nutrient-poor conditions (i.e. relaxing upwelling conditions). However, it also occurred during some upwelling events of colder, nutrient-rich subsurface waters onto the continental shelf. Minimum abundances were generally found during downwelling periods, with unexpectedly high coccolith abundance registered in subsurface waters at the inner-shelf station. This finding can only be explained if strong storms during these downwelling periods favoured resuspension processes, thus remobilizing deposited coccoliths from surface sediments, and hence hampering the identification of autochthonous coccolithophore community structure. At both locations, the major coccolithophore assemblages were dominated by Emiliania huxleyi, small Gephyrocapsa group, Gephyrocapsa oceanica, Florisphaera profunda, Syracosphaera spp., Coronosphaera mediterranea, and Calcidiscus leptoporus. Ecological preferences of the different taxa were assessed by exploring the relationships between environmental conditions and temporal and vertical variability in coccosphere abundance. These findings provide relevant information for the use of fossil coccolith assemblages in marine sediment records, in order to infer past environmental conditions, of particular importance for Paleoceanography. Both E. huxleyi and the small Gephyrocapsa group are proposed as proxies for the upwelling regime with a distinct affinity for different stages of the upwelling event: E. huxleyi was associated with warmer, nutrient-poor and more stable water column (i.e. upwelling relaxation stage) while the small Gephyrocapsa group was linked to colder waters and higher nutrient availability (i.e. early stages of the upwelling event), similarly to G. oceanica. Conversely, F. profunda is suggested as a proxy for the downwelling regime and low-productivity conditions. The assemblage composed by Syracosphaera pulchra, Coronosphaera mediterranea, and Rhabdosphaera clavigera may be a useful indicator of the presence of subtropical waters conveyed northward by the Iberian Poleward Current. Finally, C. leptoporus is proposed as an indicator of warmer, saltier, and oligotrophic waters during the downwelling/winter regime.EXCAPA project - Xunta de Galicia [10MDS402013PR]; CALIBERIA project (Fundacao para a Ciencia e a Tecnologia - Portugal) [PTDC/MAR/102045/2008]; CALIBERIA project [COMPETE/FEDER-FCOMP-01-0124-FEDER-010599, BI/PTDC/MAR/102045/2008/2010-016, BI/PTDC/MAR/102045/2008/2010-022, BI/PTDC/MAR/102045/2008/2011-027]; Ministerio de Economia y Competitividad [CGL2015-68459-P]; Ministry of Education of Spain [AP2010-2559]; ETH Zurich Postdoctoral Fellowship from the Swiss Federal Institute of Technology in Zurich (ETHZ); Xunta de Galicia (Spain); FCT [SFRH/BPD/111433/2015]; Plurianual/Estrategico project [UID/Multi/04326/2013]info:eu-repo/semantics/publishedVersio
