Adaptation and Validation of the Spanish Version of the Instrument to Evaluate Nurses’ Attitudes Toward Communication With the Patient for Nursing St…
2021
Communication is essential to quality of care and patient satisfaction. It has been linked to positive patient outcomes, increased engagement, improved health outcomes and safe practices. Given these benefits and the association between attitudes and behaviours, as behaviours can be predicted by studying attitudes, assessing nursing students' attitudes toward patient communication is critical as future nursing professionals. For this purpose, the main aim of this study was to adapt and validate an instrument to measure nurses´ attitudes towards communication (ACO) for nursing students. The attitudes towards communication with patients were analyzed. Then, differences in the dimensions of th…
El fenómeno del sexting entre los adolescentes españoles: prevalencia, actitudes, motivaciones y variables explicativas
2020
Resumen: El sexting es un fenómeno que consiste en el envío y la recepción de fotos, videos y/o mensajes de texto de naturaleza sexual a través de smartphones. Como en todos los demás países desarrollados, se está convirtiendo en una práctica cada vez más popular entre los adolescentes de España. Al tratarse de un fenómeno muy reciente todavía no existen muchos trabajos que hayan estudiado con profundidad su entidad y sus factores implicados. Por tanto, los dos objetivos de este estudio fueron determinar la prevalencia y analizar las variables explicativas del inicio y del mantenimiento de las conductas de sexting. La muestra estuvo formada por 784 adolescentes españoles (52% chicos y 48% c…
Tinkering with the two-to-one interview: Reflections on the use of two interviewers in qualitative constructionist inquiry
2021
Abstract Typically, qualitative interviews implicate a single interviewer. In this article, we consider an alternative comprising the simultaneous, active involvement of two interviewers. We base our considerations on experiences using the two-to-one interview in a nationwide research project on disability and physical activity. In addition to untapping and developing a qualitative interview method, the article provides an example in action of tinkering in qualitative inquiry. Tinkering entails a constant questioning of what to do, what is best, and what is appropriate within each moment of the research. Echoing social constructionist scholars, we argue that this flexible approach is useful…
Immersive Versus Non-immersive Experience: Exploring the Feasibility of Memory Assessment Through 360° Technology
2019
Episodic memory is essential to effectively perform a number of daily activities, as it enables individuals to consciously recall experiences within their spatial and temporal environments. Virtual Reality (VR) serves as an efficacious instrument to assess cognitive functions like attention and memory. Previous studies have adopted computer-simulated VR to assess memory, which realized greater benefits compared to traditional procedures (paper and pencil). One of the most recent trends of immersive VR experiences is the 360° technology. In order to evaluate its capabilities, this study aims to compare memory performance through two tasks: immersive task and non-immersive task. These tasks d…
La adaptación cultural en estudiantes extranjeros
2015
En este trabajo, se desarrolla el concepto de adaptación cultural, particularmente se aborda la adaptación de los estudiantes extranjeros. Se plantean diferentes modelos explicativos y se comentan diferentes niveles de adaptación. Se trabaja con conceptos como aculturación y estrés por aculturación. Por último, se comentan algunas de las investigaciones que abordaron los factores que favorecen la integración del estudiante extranjero.
The activating receptor NKG2D of natural killer cells promotes resistance against enterovirus-mediated inflammatory cardiomyopathy
2014
In enterovirus-induced cardiomyopathy, information regarding the detailed impact of natural killer (NK) cells on the outcome of the disease is limited. We therefore hypothesized that NK cells and certain NK cell receptors determine the different outcome of coxsackievirus B3 (CVB3) myocarditis. Here, we demonstrate in murine models that resistance to chronic CVB3 myocarditis in immunocompetent C57BL/6 mice is characterized by significantly more mature CD11b(high) NK cells, the presence of NKG2D on NK cells, and enhanced NKG2D-dependent cytotoxicity compared to CVB3-susceptible A.BY/SnJ mice. The highly protective role of NKG2D in myocarditis was further proven by in vivo neutralization of NK…
RORgamma-expressing Th17 cells induce murine chronic intestinal inflammation via redundant effects of IL-17A and IL-17F.
2008
Background and Aims IL-17–producing CD4 + T-helper cells (Th17) contribute to chronic autoimmune inflammation in the brain, and levels of Th17-derived cytokines increase in patients with colitis, suggesting a role in pathogenesis. We analyzed the roles of Th17 cells and the transcription factor retinoic acid receptor-related organ receptor (ROR)γ, which regulates Th17 differentiation, in chronic intestinal inflammation. Methods Using an adoptive transfer model of colitis, we compared the colitogenic potential of wild-type, interleukin-17A (IL-17A)–, IL-17F–, IL-22–, and RORγ-deficient CD4 + CD25 − T cells in RAG1-null mice. Results Adoptive transfer of IL-17A–, IL-17F–, or IL-22–deficient T…
Preditores de compreensão de leitura em adultos Europeus
2021
Research on the predictors of reading comprehension has been largely focused on school-aged children and mainly in opaque orthographies, hindering the generalization of the results to adult populations and more transparent orthographies. In the present study, we aim to test two versions of the Simple View of Reading (SVR): the original model and an extended version, including reading fluency and vocabulary. Additional mediation models were analyzed to verify if other reading comprehension predictors (rapid automatized naming, phonological decoding, phonological awareness, morphological awareness, and working memory) have direct effects or if they are mediated through word reading and readin…
A double-negative (IgD−CD27−) B cell population is increased in the peripheral blood of elderly people
2009
The T cell branch of the immune system has been extensively studied in the elderly and it is known that the elderly have impaired immune function, mainly due to the chronic antigenic load that ultimately causes shrinkage of the T cell repertoire and filling of the immunologic space with memory T cells. In the present paper, we describe the IgD(-)CD27(-) double-negative B cell population which (as we have recently described) is higher in the elderly. Most of these cells were IgG(+). Evaluation of the telomere length and expression of the ABCB1 transporter and anti-apoptotic molecule, Bcl2, shows that they have the markers of memory B cells. We also show that these cells do not act as antigen…
Association study of suicidal behavior and affective disorders with a genetic polymorphism in ABCG1, a positional candidate on chromosome 21q22.3
2000
The gene that codes for the ABC transporter ABCG1 is located in a chromosomal susceptibility region (21q22.3) for affective disorders. Genetic variations in ABCG1 have been associated with affective disorders in Japanese males. In this study, we investigated the distribution of a G2457A polymorphism in patients with affective disorders, suicide attempters with various psychiatric diagnoses and healthy subjects. We initially found a trend towards a modest association with affective disorders in males (p = 0.046 for allele frequencies and p = 0.046 for AA versus GG). We conducted a replication study with independent patients and controls. There was no association with affective disorders, eit…
