Implantación de una Unidad de Ortogeriatría de Agudos en un hospital de segundo nivel

Background

Patients with hip fracture (HF), due to their characteristics, require a specific support. The Acute Orthogeriatric Unit (OGU) has been shown to be one of the most beneficial.

Objective

To evaluate the main variables of HF patients treated at an OGU and compare them with the previous referral model (RC).

Material and methods

A prospective observational study with retrospective control was conducted on 169 patients, split into two groups. In the RC group, patients were admitted to conventional trauma ward. In the OGU group, an early geriatric assessment was performed, and patients were simultaneously attended daily by the orthopaedic surgeon, nurse and geriatrician, and the surgery times, work load, discharge and destination, were planned in a weekly meeting with the rest of professionals.

Results

A total of 71 patients were included in the RC group and 96 in the OGU group. The preoperative characteristics were similar, except for a slightly higher comorbidity in the OGU group. The OGU patients were operated on earlier (3.82±2.08 vs 4.61±2.5 days; P<.32), and overall hospital stay was reduced by 28% (11.84±4.04 vs 16.46±8.4 days; P<.001). The functional efficiency (Barthel Index at discharge-Barthel Index at admission/overall stay - stay before surgery) was higher in the OGU group (1.56±0.7 vs 2.61±1.1; P<.05). There were no differences in functional status, mortality or discharge location.

Conclusions

The OGU is a level of care that provides effective medical care in HF patients in general hospitals.     

Seasonal variation of circulating plasma carotenoids in Mediterranean Great Tit males Parus major

Capsule Mediterranean Great Tits showed a marked increase in levels of circulating carotenoids during moult and autumn.

Aims To study seasonal variation in plasma carotenoid content during a whole annual cycle for Great Tits Parus major inhabiting a Mediterranean woodland.

Methods We used a sample of 71 adult male Great Tits captured in NE Spain during a whole year. Data were organized into four seasons (winter, breeding, moult and autumn). We sampled blood to extract plasma. Carotenoid plasma concentrations were analysed by High-performance liquid chromatography (HPLC).

Results Lutein and zeaxanthin content varied seasonally, with a marked increase in levels during moult and autumn. Within the moulting period, levels increased gradually as the season progressed. This pattern differed significantly from that previously described in northern European populations, where high values appear mainly in the breeding season. Carotenoid concentrations (lutein: 1.2?±?0.25, zeaxanthin: 0.07?±?0.03?µg mL^?1) were also lower than in northern Europe.

Conclusion Mediterranean Great Tits show a very different pattern of circulating carotenoids and lower levels than northern European populations. The increasing pattern of carotenoid availability found within the moulting period raises the need to control for the effect of sampling date when analysing data on carotenoid concentrations at different times of year.     

Modelling the nesting-habitat of the Cinereous Vulture Aegypius monachus on a fine scale for conservation purposes

Capsule Nests of Cinereous Vultures were found to be located farther from roads, villages and the edge of large vegetation patches. They preferred large vegetation patches containing extensive Cork Oak cover on steeper slopes and with lower solar radiation. Less than 8% of the study area was predicted to be suitable for nesting.

Aims To generate a predictive habitat suitability map for the Cinereous Vulture's nesting-habitat on a fine scale for conservation applications within its breeding range.

Methods Habitat features of 43 nest-locations and random points were compared in order to identify nest-habitat selected in the region of the Hornachuelos Natural Park (Spain). A logistic regression approach was used to create habitat models.

Results Compared with random points, nests were found to be located farther from roads, villages and patch edges, and in large vegetation patches containing extensive Cork Oak cover on steeper slopes with lower solar radiation. The predictive map revealed that less than 8% of the study area had a greater probability of occupancy than 0.8.

Conclusions Most habitats in the study area are unsuitable for nesting suggesting that conservation of the best suitable areas is important. The fine-scale predictive map approach may be valuable in designating conservation priority areas.     

Condition of large brood in Bonelli's Eagle Hieraaetus fasciatus

Capsule Young body condition is affected by the interaction of environment (rainfall) and brood size.

Aims To investigate factors affecting offspring condition using levels of urea in plasma.

Methods We used generalized linear mixed models (GLMMs) with the levels of urea in plasma as the dependent variable and laying date, brood size, sex and year as the explanatory ones.

Results Brood size had a significant effect on offspring condition only during a year of adverse weather (heavy rainfall). During this period, young from broods of two were in poor condition compared with single broods. Conversely, brood size had no effect in the other two years analysed. Neither sex nor laying date had a significant effect on young condition. Offspring condition was not related to first-year survival.

Conclusion There is a trade-off between reproduction (brood size) and offspring condition only in years of adverse environmental conditions.     

Adoptions in a coδoperative population of Carrion Crow Corvus corone corone

Capsule Adoptions occurred at low rate (2.6% of successful nests and 1.1% of fledglings), probably as a result of a mistake in early offspring recognition.     

A new exotic bird in Europe: recent spread and potential range of Red‐billed Leiothrix Leiothrix lutea in Catalonia (northeast Iberian Peninsula)

Capsule Following recent introduction in Spain, Red‐billed Leiothrix have the potential to attain a wide distribution in Catalonia and probably in other parts of Europe.

Aim To investigate past, present and potential distribution of this exotic species in Catalonia (northeast Iberian Peninsula).

Methods We collected data on the species’ occurrence over the period 1992–2008 and used information obtained in other regions where it has previously established to produce hypotheses about the ecological processes that affect its population increase and range expansion. We then generated fine‐grained distribution maps covering the entire region for the periods 1992–2001 and 2002–2008, and for the species’ potential range according to its specific habitat requirements.

Results Since being first detected in the wild in the Collserola Park, near the city of Barcelona, Red‐billed Leiothrix have expanded to neighbouring forested areas. The wild population is currently in a phase of exponential growth and, according to our habitat suitability model, the species’ potential distribution in Catalonia might be 36 times greater than at present.

Conclusion Our results suggest that the Red‐billed Leiothrix has the potential to attain a widespread distribution over large regions of Europe in the near future. However, we discuss several factors that might affect these predictions.     

Synopsis of the tribe Hureae (Euphorbioideae, Euphorbiaceae)

A synopsis of the tribe Hureae is presented with nomenclatural updates, a discussion of diagnostic features, and summaries of geographical distributions. This study is based on the analysis of approximately 300 voucher specimens, including collections and photographs of types, in addition to bibliographic documentation. Seventeen species distributed in three genera were recognized: Algernonia (11 species), Hura (2), and Ophthalmoblapton (4). All species are American with the majority distributed within the Atlantic Forest, particularly in southeastern Brazil. A key for the identification of genera and species is provided along with illustrations, information on the geographic distributions and conservation status. Lectotypification for Algernonia leandrii is proposed.
