Design and psychometric evaluation of the 'Clinical Communication Self-Efficacy Toolkit'

Nursing students experience difficulties when communicating in clinical practice. Their self-efficacy in clinical communication should be explored as part of their competence assessment before they are exposed to real human interactions in the clinical setting. The aim of this study was to design and psychometrically evaluate a toolkit to comprehensively assess nursing students’ self-efficacy in clinical communication. The study followed an observational cross-sectional design. A sample of 365 nursing students participated in the study. The ‘Clinical Communication Self-Efficacy Toolkit’ (CC-SET) was comprised of three tools: the ‘Patient-Centered Communication Self-efficacy Scale’ (PCC-SES), the ‘Patient clinical Information Exchange and interprofessional communication Self-Efficacy Scale’ (PIE-SES), and the ‘Intrapersonal communication and Self-Reflection Self-Efficacy Scale’ (ISR-SES). The tools’ reliability, validity (content, criterion, and construct) and usability were rigorously tested. The Cronbach’s alpha coefficient of the three tools comprising the CC-SET was very high and demonstrated their excellent reliability (PCC-SES = 0.93; PIE-SES = 0.87; ISR-SES = 0.86). The three tools evidenced to have excellent content validity (scales’ content validity index > 0.95) and very good criterion validity. Construct validity analysis demonstrated that the PCC-SES, PIE-SES, and ISR-SES have a clear and theoretically-congruent structure. The CC-SET is a comprehensive toolkit that allows the assessment of nursing students’ self-efficacy in interpersonal, interprofessional, and intrapersonal communication

Koilocytes are enriched for alkaline-labile sites

This study investigated possible variations in the chromatin structure of koilocytes resulting from human papillomavirus (HPV) infection. Alkaline-labile sites (ALS) were detected with the DNA breakage detection–fluorescence in situ hybridization (DBD-FISH) technique using a whole human genome DNA probe obtained from individuals without koilocytosis. The variable levels of ALS present were measured quantitatively using image analysis after whole-genome DNA hybridization. A significant increase in the number of ALS was observed in koilocytes compared with normal cells. We demonstrated that the presence of ALS could be an indicator of chromatin change in koilocytes caused by HPV infection

Experiences of mothers of extremely preterm infants after hospital discharge

The purpose of this study was to describe and understand the experiences of mothers of extremely preterm infants during the first twelve months at home following discharge from a neonatal intensive care unit. A qualitative, interpretative approach using Gadamer's philosophical hermeneutics was carried out. One focus group and fifteen in-depth, semi-structured interviews were conducted twelve months after hospital discharge. Responses were recorded, transcribed and analyzed using computer-assisted qualitative data analysis. The study´s participants were twenty women. The following themes emerged from the data analysis: 1) 'The journey home: the discharge process', which included the sub-themes 'escaping the hospital environment: between desire and fear' and 'preparing parents for hospital discharge: practice and formal support'; and 2) 'The difficulty of living with an extremely preterm infant', including the sub-themes 'the challenge of an unexpected form of childcare', 'overprotection of and bond with a child with special needs' and 'disturbance in the social/familiar setting: when a mother becomes a nurse'. The process of hospital discharge and the first months at home are difficult. The birth and care of an extremely preterm infant affect the mothers' quality of life as well as their family and social life. Practice and early discharge programmes can make the discharge process easier. The knowledge and understanding of the experience of mothers of extremely preterm infants in the first months at home after hospital discharge could help healthcare professionals to develop educational strategies and counselling interventions in accordance with the mothers' needs.

Effects of a simulation-based workshop on nursing students' competence in arterial puncture

Objective: To evaluate whether a short simulation-based workshop in radial artery puncture would improve nursing students’ competence to a level in which they could practise the procedure on a live patient without compromising his safety. Methods: Quasi-experimental one-group pretest-posttest study with 111 third-year nursing students. A 1.5-hour simulation-based workshop was implemented. This included a video-lecture, live demonstrations, selfdirected simulated practice in dyads and individual intermittent feedback. Participants’ skills, knowledge and self-efficacy in arterial puncture were measured before and after attending the workshop. Results: After the intervention, a total of 61.1% of the participants showed the level of competence required to safely practice radial artery puncture on a live patient under supervision. Conclusion: Effective simulation-based training in arterial puncture for nursing students does not necessarily need to be resource-intensive. Well-planned, evidence-based training sessions using low-tech simulators could help educators to achieve good educational outcomes and promote patient safety

Habilidades del psicólogo en drogodependencias

Las habilidades del terapeuta constituyen un aspecto fundamental para la consecución de los distintos objetivos que al psicólogo se le plantean en el transcurso de su intervención con el usuario drogodependiente. En este articulo se presenta una revisión de las habilidades que los autores consideran imprescindibles, aportando ejemplos prácticos y con independencia de la orientación teórica del psicólogo. Las habilidades técnicas o profesionales se refieren a conocimientos teóricos y prácticos; el afltocontrol emocional, incluyendo tanto el afrontamiento ef caz por parte del psicólogo de ciertas situaciones ante el usuario, y especificamente si éste es un drogodelincuente, como el afrontamiento del burn out; y por último, las habilidades sociales, en las que se sustenta la interacción entre el psicólogo y el usuario, destacando la asertividad y la empatia. Finalmente se revisan distintos aspectos y principios generales referidos a la ética profesional en la práctica de la Psicologia Clínica

Controlled Anisotropic Deformation of Ag Nanoparticles by Si Ion Irradiation

The shape and alignment of silver nanoparticles embedded in a glass matrix is controlled using silicon ion irradiation. Symmetric silver nanoparticles are transformed into anisotropic particles whose larger axis is along the ion beam. Upon irradiation, the surface plasmon resonance of symmetric particles splits into two resonances whose separation depends on the fluence of the ion irradiation. Simulations of the optical absorbance show that the anisotropy is caused by the deformation and alignment of the nanoparticles, and that both properties are controlled with the irradiation fluence.Comment: Submitted to Phys.

Approach to anaerobic bio-degradation of natural and synthetic fabrics: Physico-chemical study of the alteration processes

In this paper, the mesophilic Biochemical Methane Potential of several fabrics was assessed at different Total Solid concentrations (1–4%TS). Physico-chemical techniques were applied to explore the arising structural changes on fibers during the anaerobic digestion process. Additionally, the modified Gompertz model was used to assess and compare the AD performance of the fabrics. In cellulose-based fibers the production of biogas was enhanced thanks to the easy solubilization of acetate, which is generated upon partial breakage of cellulose bonds. The crystallinity of vegetal fibers decreased significantly from day 19. The highest methane yields were attained for silk and wool fabrics at the lowest TS concentrations. Conformational changes in fibroin and keratin were detected. The highest degrees of degradation were observed in solid samples with lower solid concentrations. Accordingly, the maximum methane yields were reported in the reactors operating with lower TS

Limited genetic antagonism between premium cuts yield and intramuscular fat content in Iberian pigs

Ponencia publicada en ITEA, vol.104La producción de cerdo ibérico está orientada a la obtención de materia prima para la elaboración de productos curados de alta calidad, determinada entre otros factores por el contenido en grasa intramuscular. Este trabajo tiene como objetivo estimar las correlaciones genéticas entre el contenido de grasa intramuscular, medido mediante tecnología NIRS en M. longissimus, y los principales caracteres productivos: porcentaje de jamones, paletas y lomos del peso de la canal, y la ganancia media diaria durante el periodo de ‘Montanera’. Los registros analizados proceden de 6.103 cerdos castrados de 56 ganaderías y controlados desde 1993 al 2007 por AECERIBER. Los animales con un manejo extensivo común fueron sacrificados, en 79 lotes, a un peso medio de aproximadamente 160 kg. Las heredabilidades estimadas presentaron valores altos para todos los caracteres (0,37 a 0,48) indicando que la selección para todos los caracteres puede ser efectiva. Las correlaciones genéticas entre el porcentaje de las principales piezas nobles fueron altas y positivas (de 0,36 a 0,69) lo cual indica que dichos caracteres están en parte controlados por un mismo grupo de genes. Las correlaciones genéticas entre el contenido en grasa intramuscular y ganancia media diaria y el porcentaje de paletas no fueron significativamente diferentes de cero. Sin embargo, se estimaron efectos negativos significativos entre el contenido en grasa intramuscular y el porcentaje de jamones (-0.19 ± 0.04) y lomos (-0.23 ± 0.03). Estos valores indican que una intensa selección orientada a mejorar el porcentaje de piezas nobles de la canal, puede a medio plazo deteriorar la calidad de los productos curados en cerdos Ibéricos.The production of Iberian pigs is mainly focused to obtain raw meat to elaborate dry-cured products of high sensorial quality, mainly influenced by the intramuscular fat content. The objective of this work was to estimate the genetic correlations between intramuscular fat content in M. longissimus, measured using NIRS technology, and the main productive traits: percentages on carcass weight of hams, forelegs and loins, and the daily growth along the final fattening period. Records for this analysis came from 6,103 castrate males, born in 56 herds and controlled by AECERIBER from 1993 to 2007. All the animals were fattened with a common extensive management system and slaughtered, distributed in 79 batches, at approximately 160 kg. Heritability estimates presented high values for all the traits (ranging between 0.37 and 0.48) indicating that the selection for these traits could be effective. Genetic correlations between percentages of premium cuts were high and positive (from 0.36 to 0.69). This fact indicates that these traits are partially controlled by the same group of genes. Genetic correlations between intramuscular fat content and the daily growth and percentage of forelegs showed estimated values statistically non different from cero. However, significant negative values of genetic correlations were estimated between intramuscular fat content and the percentages of hams (-0.19 ± 0.04) and loins (-0.23 ± 0.03). These last values indicate that a strong selection in Iberian pigs focused to the improvement of the carcass percentage of premium cuts, could cause a deterioration of the meat suitability for dry-curing in a medium-time horizon
