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

Cross-Cultural Validation of the Falls Efficacy Scale International in Elderly: Systematic Literature Review

The aim of this study is to describe the psychometric properties of cultural adaptations of the Falls Efficacy Scale International (FES-I) in the elderly dwelling in the community. A systematic literature review was performed according to the research question: What are the psychometric properties of the FES-I in the elderly dwelling in the community in different cultural backgrounds? The Population, Interest, Context (PICo) strategy was used for inclusion criteriadPopulation: elderly; Interest area/intervention: psychometric properties of the FES-I; Context: dwelling in the community in various cultural settings. The sample was made up of 10 articles. Metric properties have been evaluated by the criteria of validity, reproducibility, reliability, and responsiveness. The FES-I is considered acceptable, understandable to measure the fear of falling in the elderly, valid, reliable, and comparable cross-culturally, so it is recommended in rehabilitation research, clinical trials, clinical practice, and in fall-prevention programs in elderly.info:eu-repo/semantics/publishedVersio

Validation of the Multidimensional Sense of Humor Scale in People with Chronic Kidney Disease

Multidimensional Sense of Humor Scale (MSHS) was developed by Thorson and Powell and it was validated in Portuguese, but not in people with chronic kidney disease (CKD). This study examined the psychometrics of the MSHS in people with CKD on hemodialysis. A random sample of 171 people with CKD undergoing hemodialysis was selected. Exploratory Factor Analysis revealed a structure with three factors, “Humor Production and Social Use of Humor”, “Adaptive Humor and Appreciation Humor” and “Attitude Towards Humor”, with Alpha Cronbach values of 0.93, 0.90 and 0.83 respectively. It revealed stability in both interview and questionnaire methods. It showed moderate positive correlations with Positive Affect, Subjective Happiness and Wellbeing Personal Index, and moderate negative correlation with Negative Affect. Therefore, MSHS shows evidence of being a valid, reliable and reproducible scale either by questionnaire or interview.info:eu-repo/semantics/publishedVersio

Inhibitory action of phenothiazinium dyes against Neospora caninum.

Neospora caninum is an Apicomplexan parasite related to important losses in livestock, causing abortions and decreased fertility in affected cows. Several chemotherapeutic strategies have been developed for disease control; however, no commercial treatment is available. Among the candidate drugs against neosporosis, phenothiazinium dyes, offer a low cost-efficient approach to parasite control. We report the anti-parasitic effects of the phenothiaziums Methylene Blue (MB), New Methylene Blue (NMB), 1,9-Dimethyl Methylene Blue (DMMB) and Toluidine Blue O (TBO) on N. caninum, using in vitro and in vivo models. The dyes inhibited parasite proliferation at nanomolar concentrations (0.019-1.83 μM) and a synergistic effect was achieved when Methylene Blue was combined with New Methylene Blue (Combination Index = 0.84). Moreover, the phenothiazinium dyes improved parasite clearance when combined with Pyrimethamine (Pyr). Combination of Methylene Blue + 1,9-Dimethyl Methylene Blue demonstrated superior efficacy compared to Pyrimethamine based counterparts in an in vivo model of infection. We also observed that Methylene Blue, New Methylene Blue and 1,9-Dimethyl Methylene Blue increased by 5000% the reactive oxygen species (ROS) levels in N. caninum tachyzoites. Phenothiazinium dyes represent an accessible group of candidates with the potential to compound future formulations for neosporosis control

In vitro co-culture of Solanum tuberosum hairy roots with Meloidogyne chitwoodi: structure, growth and production of volatiles

Meloidogyne spp., commonly known as root- knot nematodes (RKNs), are economically important plant sedentary endoparasites that cause galls on susceptible hosts. The Columbia root-knot nematode (CRKN), M. chitwoodi, is a quarantine A2 type pest by the European and Mediterranean Plant Protection Organization since 1998. This nematode has been found associated with economi- cally important crops such as potato and tomato, causing severe damage and making the agricultural products unac- ceptable for the fresh market and food processing. In vitro co-culture of host and parasite offers an advantageous experimental system for studying plant-RKN interactions. The structure, growth and production of volatiles of Sola- num tuberosum hairy roots (HR) and of S. tuberosum HR/ CRKN co-cultures were compared. HR were induced by inoculation of aseptic potato tuber segments with Rhizo- bium rhizogenes. Co-cultures were initiated by inoculating HR with sterilized CRKN eggs. Infection with CRKN induced the RKN symptomatology in the HR and several nematode life stages were observed by light and scanning electron microscopy. Potato HR and HR/CRKN co-culturesexhibited similar growth patterns, evaluated by measuring fresh and dry weight and by the dissimilation method. Volatiles, isolated by distillation–extraction and analyzed by gas chromatography (GC) and gas chromatography coupled to mass spectrometry, revealed that palmitic acid (37–52 %), n–pentadecanal (10–16 %) and linoleic acid (2–16 %) were the main constitutive components of S. tu- berosum HR, and of the HR/CRKN co-cultures (24–44, 8–22 and 4–18 %, respectively). S. tuberosum HR/CRKN co-cultures can be considered a suitable biotechnological tool to study RKN infection mechanism by mimicking what occurs under field conditions
