Riesgo de Caídas de los Ancianos Residentes en la Comunidad: Revisión Sistemática de la Literatura

OBJECTIVE: To identify the risk factors for falls of the community-dwelling elderly in order to update the Taxonomy II of NANDA International. METHOD: A systematic literature review based on research using the following platforms: EBSCOHost®, CINAHL and MEDLINE, from December 2010 to December 2014. The descriptors used were (Fall* OR Accidental Fall) AND (Community Dwelling OR Community Health Services OR Primary health care) AND (Risk OR Risk Assessment OR Fall Risk Factors) AND (Fall* OR Accidental Fall) AND (Community Dwelling OR older) AND Nurs* AND Fall Risk Factors. RESULTS: The sample comprised 62 studies and 50 risk factors have been identified. Of these risk factors, only 38 are already listed in the classification. CONCLUSIONS: Two new categories of risk factors are proposed: psychological and socio-economical. New fall risk factors for the community-dwelling elderly have been identified, which can contribute to the updating of this nursing diagnosis of the Taxonomy II of NANDA International.info:eu-repo/semantics/publishedVersio

Assessment Tools of Risk for Falls in Elderly Dwelling in the Community

Las caídas y el riesgo de caer aumentan con la edad y con el grado de fragilidad asociado al envejecimiento, siendo este el motivo por el cual el riesgo de caídas es un fenómeno de interés para los enfermeros. En Portugal, la Dirección General de Salud recomienda la realización de pruebas de evaluación de la movilidad, la capacidad física y funcional. Objetivo: Identificar los instrumentos utilizados para evaluar el riesgo de caída en el anciano residente en la comunidad.Método: Revisión sistemática de la literatura, cumpliendo las recomendaciones del Joanna Briggs Institute a través de la utilización del método PICo y de las recomendaciones PRISMA. El método PICo ayudó a definir los criterios de inclusión: Muestra (P) - los ancianos; Área de Interés (I) - instrumentos y pruebas que permiten evaluar el riesgo de caídas, y Contexto (Co) - vivir en la comunidad. La consulta bibliográfica fue realizada a través de las bases de datos: EBSCOHost®, CINAHL Complete y MEDLINE Complete, y utilizando los términos; fall, community dwelling, fall risk factors y tools escale. Resultados: Fueron seleccionados 24 estudios, en los que se identificaron seis escalas que evaluaban el riesgo de caídas, tres el miedo de caer y siete que evaluaban factores de riesgo predictivos del riesgo de caída, en ancianos que residen en la comunidad. Conclusiones: Los resultados destacan el número de instrumentos disponibles y la importancia de la utilización práctica por parte de los enfermeros de instrumentos válidos, fidedignos y sensibles, de modo de obtener diagnósticos precisos.info:eu-repo/semantics/publishedVersio

Enhancement of nematic order and global phase diagram of a lattice model for coupled nematic systems

We use an infinite-range Maier-Saupe model, with two sets of local quadrupolar variables and restricted orientations, to investigate the global phase diagram of a coupled system of two nematic subsystems. The free energy and the equations of state are exactly calculated by standard techniques of statistical mechanics. The nematic-isotropic transition temperature of system A increases with both the interaction energy among mesogens of system B, and the two-subsystem coupling $J$. This enhancement of the nematic phase is manifested in a global phase diagram in terms of the interaction parameters and the temperature $T$. We make some comments on the connections of these results with experimental findings for a system of diluted ferroelectric nanoparticles embedded in a nematic liquid-crystalline environment.Comment: 11 pages, 3 figures, to appear in Volume 42 of the Brazilian Journal of Physic

Uncommon genetic syndromes and narrative production - Case Studies with Williams, Smith-Magenis and Prader- Willi Syndromes

This study compares narrative production among three syndromes with genetic microdeletions: Williams syndrome (WS), Smith-Magenis syndrome (SMS), and Prader-Willi syndrome (PWS), characterized by intellectual disabilities and relatively spared language abilities. Our objective is to study the quality of narrative production in the context of a common intellectual disability. To elicit a narrative production, the task Frog! Where Are You was used. Then, structure, process, and content of the narrative process were analysed in the three genetic disorders:WS (n52), SMS (n52), and PWS (n52). Data show evidence of an overall low narrative quality in these syndromes, despite a high variability within different measures of narrative production. Results support the hypothesis that narrative is a highly complex cognitive process and that, in a context of intellectual disability, there is no evidence of particular ‘hypernarrativity’ in these syndromes.This research was supported by the grants FEDER –

Observation of associated near-side and away-side long-range correlations in √sNN=5.02 TeV proton-lead collisions with the ATLAS detector

Two-particle correlations in relative azimuthal angle (Δϕ) and pseudorapidity (Δη) are measured in √sNN=5.02  TeV p+Pb collisions using the ATLAS detector at the LHC. The measurements are performed using approximately 1  μb-1 of data as a function of transverse momentum (pT) and the transverse energy (ΣETPb) summed over 3.1<η<4.9 in the direction of the Pb beam. The correlation function, constructed from charged particles, exhibits a long-range (2<|Δη|<5) “near-side” (Δϕ∼0) correlation that grows rapidly with increasing ΣETPb. A long-range “away-side” (Δϕ∼π) correlation, obtained by subtracting the expected contributions from recoiling dijets and other sources estimated using events with small ΣETPb, is found to match the near-side correlation in magnitude, shape (in Δη and Δϕ) and ΣETPb dependence. The resultant Δϕ correlation is approximately symmetric about π/2, and is consistent with a dominant cos⁡2Δϕ modulation for all ΣETPb ranges and particle pT

The Antibacterial Activity of Honey Derived from Australian Flora

Chronic wound infections and antibiotic resistance are driving interest in antimicrobial treatments that have generally been considered complementary, including antimicrobially active honey. Australia has unique native flora and produces honey with a wide range of different physicochemical properties. In this study we surveyed 477 honey samples, derived from native and exotic plants from various regions of Australia, for their antibacterial activity using an established screening protocol. A level of activity considered potentially therapeutically useful was found in 274 (57%) of the honey samples, with exceptional activity seen in samples derived from marri (Corymbia calophylla), jarrah (Eucalyptus marginata) and jellybush (Leptospermum polygalifolium). In most cases the antibacterial activity was attributable to hydrogen peroxide produced by the bee-derived enzyme glucose oxidase. Non-hydrogen peroxide activity was detected in 80 (16.8%) samples, and was most consistently seen in honey produced from Leptospermum spp. Testing over time found the hydrogen peroxide-dependent activity in honey decreased, in some cases by 100%, and this activity was more stable at 4°C than at 25°C. In contrast, the non-hydrogen peroxide activity of Leptospermum honey samples increased, and this was greatest in samples stored at 25°C. The stability of non-peroxide activity from other honeys was more variable, suggesting this activity may have a different cause. We conclude that many Australian honeys have clinical potential, and that further studies into the composition and stability of their active constituents are warranted
