AppDIXITOU: xogo educativo para móbil co que se conciencia a xente adolescente no bo uso das redes sociais

Hoxe en día, a maioría da xente adolescente posúe un móbil e boa parte dela usa as redes sociais para socializar. Pero, ata que punto saben como usalas correctamente? Este traballo describe a necesidade e o desenvolvemento dunha ferramenta informática educativa para o móbil (AppDIXITOU), na que se aplica a gamificación coa pretensión de concienciar e de educar nun uso máis racional e saudable das redes sociais o estudantado de educación secundaria obrigatoria da provincia de Ourense. Unha das recomendacións que realizan diversos estudos para reducir os perigos, que afrontan os e as menores cando empregan as redes sociais, consiste en realizar campañas formativas destinadas a eles e elas onde, ademais de informalos deses riscos,se intente modificar o seu comportamento ante o uso destas. AppDIXITOU pretende formar parte desa «misión». Este soporte lóxico (software) desenvolveuse para que se use nun móbil, dispositivo tan cotián hoxe en día entre a xente adolescente. Despois dun estudo sobre o sistema operativo para móbil máis empregado entre os móbiles que dispoñen a maioría da mocidade, decidiuse que a aplicación funcione sobre Android. A gamificación é o uso do pensamento e a mecánica de xogabilidade en contextos alleos aos xogos, co fin de que as persoas adopten certo comportamento. Se se aplica ao ámbito educativo, a finalidade desta técnica de aprendizaxe é aumentar a motivación e favorecer o coñecemento. O obxectivo de aplicar esta metodoloxía no software desenvolvido foi dobre: por unha banda, mellorar o coñecemento que ten a poboación adolescente dos riscos que supón un uso incorrecto das redes sociais e, por outra, non menos importante, provocar cambios no comportamento destes ante situacións perigosas orixinadas polo uso das citadas redes

Traspasando las fronteras de la reflexión en la enseñanza y el aprendizaje de los idiomas

This paper reports on the first phase of an exploratory qualitative study carried out with in-service language teachers pursuing a graduate degree in Colombia. It aims at analyzing their practices, needs, and challenges, examined under two perspectives—the teacher as a learner and the teacher as a teacher. The study made use of interviews, focus groups, and questionnaires as the primary sources of data. Data analysis included a grounded theory approach and the use of coding, triangulation, and validation procedures. Results unveiled the difficulties that current in-service teachers have in different domains (cognitive, metacognitive, and linguistic), and also inform how the teaching challenges within their specific contexts influence their beliefs, practices, learning and teaching outcomes, and their professional growth. The study presents both theoretical and applied considerations to tackle the needs and challenges reported, aiming at offering a systematic analysis and approach for the endorsement of reflection, and thus, setting milestones for the enhancement of effective professional development for language teachers in educational communities such as in Colombia as well as overseas.Este manuscrito da cuenta de la primera fase de un estudio cualitativo exploratorio realizado con profesores de idiomas en ejercicio que cursan estudios de postgrado en Colombia. Su objetivo es analizar sus prácticas, necesidades y desafíos, examinados desde dos perspectivas: el profesor como estudiante y el profesor como docente. El estudio hizo uso de entrevistas, grupos focales y cuestionarios como fuentes primarias de datos. El análisis de los datos se hizo con base en la teoría fundamentada y el uso de procedimientos de codificación, triangulación y validación. Los resultados revelaron las dificultades que los actuales profesores en ejercicio tienen en los diferentes dominios (cognitivo, metacognitivo y lingüístico), y también informan sobre cómo los retos de la enseñanza en sus contextos específicos influyen en sus creencias, prácticas, resultados de aprendizaje y enseñanza, y su crecimiento profesional. El estudio presenta consideraciones teóricas y prácticas para abordar las necesidades y desafíos reportados, con el objetivo de ofrecer un análisis y enfoque sistemático para el desarrollo de la reflexión, para así establecer ejes fundamentales en el mejoramiento del desarrollo profesional de los profesores de idiomas

Competencias en enfermeras especialistas y en enfermeras de práctica avanzada

10 p.Objetivo: Analizar la distribución de competencias avanzadas en enfermeras especialistas y enfermeras de práctica avanzada y evaluar su asociación con algunas características de superfil profesional.Método: Estudio transversal analítico multicéntrico. Se incluyeron enfermeras que ejercían como Enfermeras de Práctica Avanzada y enfermeras Especialistas. Se midió su nivel de competencias avanzadas percibidas, así como variables de caracterización profesional.Resultados: Doscientas setenta y siete enfermeras participaron (149 ejercían práctica avanzada y 128 especialistas), con una media de 13,88 (11,05) años como especialista y 10,48 (5,32) años como Enfermera de Práctica Avanzada. Un 28,8% tenía nivel de máster o doctorado. El 50,2% ejercía en atención primaria, el 24,9% en hospitales y el 22,7% en salud mental. El nivel global autopercibido fue elevado en las distintas competencias, siendo las dimensiones más bajas las de investigación, práctica basada en la evidencia, gestión de la calidad y seguridad y liderazgo y consultoría. Las Enfermeras de Práctica Avanzada obtuvieron mayor nivel competencial de forma global y en las dimensiones de liderazgo y consultoría, relaciones interprofesionales, gestión de cuidados y promoción de salud. No hubo diferencias en función de la experiencia o la posesión de nivel de máster o de doctorado. En las Enfermeras de Práctica Avanzada el contexto de práctica no influía en los niveles competenciales, aunque en las enfermeras especialistas sí, a favor de las que ejercían en salud mental.Conclusiones: Las enfermeras especialistas y de práctica avanzada tienen competencias distintas que deberían ser gestionadas adecuadamente para el desarrollo de los servicios enfermeros avanzados y especializados

Stroke prevalence among the Spanish elderly: an analysis based on screening surveys

BACKGROUND: This study sought to describe stroke prevalence in Spanish elderly populations and compare it against that of other European countries. METHODS: We identified screening surveys -both published and unpublished- in Spanish populations, which fulfilled specific quality requirements and targeted prevalence of stroke in populations aged 70 years and over. Surveys covering seven geographically different populations with prevalence years in the period 1991–2002 were selected, and the respective authors were then asked to provide descriptions of the methodology and raw age-specific data by completing a questionnaire. In addition, five reported screening surveys in European populations furnished useful data for comparison purposes. Prevalence data were combined, using direct adjustment and logistic regression. RESULTS: The overall study population, resident in central and north-eastern Spain, totalled 10,647 persons and yielded 715 cases. Age-adjusted prevalences, using the European standard population, were 7.3% for men, 5.6% for women, and 6.4% for both sexes. Prevalence was significantly lower in women, OR 0.79 95% CI 0.68–0.93, increased with age, particularly among women, and displayed a threefold spatial variation with statistically significant differences. Prevalences were highest, 8.7%, in suburban, and lowest, 3.8%, in rural populations. Compared to pooled Spanish populations, statistically significant differences were seen in eight Italian populations, OR 1.39 95%CI (1.18–1.64), and in Kungsholmen, Sweden, OR 0.40 95%CI (0.27–0.58). CONCLUSION: Prevalence in central and north-eastern Spain is higher in males and in suburban areas, and displays a threefold geographic variation, with women constituting the majority of elderly stroke sufferers. Compared to reported European data, stroke prevalence in Spain can be said to be medium and presents similar age- and sex-specific traits

Genetic Cross-Interaction between APOE and PRNP in Sporadic Alzheimer's and Creutzfeldt-Jakob Diseases

Alzheimer's disease (AD) and Creutzfeldt-Jakob disease (CJD) represent two distinct clinical entities belonging to a wider group, generically named as conformational disorders that share common pathophysiologic mechanisms. It is well-established that the APOE ε4 allele and homozygosity at polymorphic codon 129 in the PRNP gene are the major genetic risk factors for AD and human prion diseases, respectively. However, the roles of PRNP in AD, and APOE in CJD are controversial. In this work, we investigated for the first time, APOE and PRNP genotypes simultaneously in 474 AD and 175 sporadic CJD (sCJD) patients compared to a common control population of 335 subjects. Differences in genotype distribution between patients and control subjects were studied by logistic regression analysis using age and gender as covariates. The effect size of risk association and synergy factors were calculated using the logistic odds ratio estimates. Our data confirmed that the presence of APOE ε4 allele is associated with a higher risk of developing AD, while homozygosity at PRNP gene constitutes a risk for sCJD. Opposite, we found no association for PRNP with AD, nor for APOE with sCJD. Interestingly, when AD and sCJD patients were stratified according to their respective main risk genes (APOE for AD, and PRNP for sCJD), we found statistically significant associations for the other gene in those strata at higher previous risk. Synergy factor analysis showed a synergistic age-dependent interaction between APOE and PRNP in both AD (SF = 3.59, p = 0.027), and sCJD (SF = 7.26, p = 0.005). We propose that this statistical epistasis can partially explain divergent data from different association studies. Moreover, these results suggest that the genetic interaction between APOE and PRNP may have a biological correlate that is indicative of shared neurodegenerative pathways involved in AD and sCJD

Effectiveness of an intervention for improving drug prescription in primary care patients with multimorbidity and polypharmacy:Study protocol of a cluster randomized clinical trial (Multi-PAP project)

This study was funded by the Fondo de Investigaciones Sanitarias ISCIII (Grant Numbers PI15/00276, PI15/00572, PI15/00996), REDISSEC (Project Numbers RD12/0001/0012, RD16/0001/0005), and the European Regional Development Fund ("A way to build Europe").Background: Multimorbidity is associated with negative effects both on people's health and on healthcare systems. A key problem linked to multimorbidity is polypharmacy, which in turn is associated with increased risk of partly preventable adverse effects, including mortality. The Ariadne principles describe a model of care based on a thorough assessment of diseases, treatments (and potential interactions), clinical status, context and preferences of patients with multimorbidity, with the aim of prioritizing and sharing realistic treatment goals that guide an individualized management. The aim of this study is to evaluate the effectiveness of a complex intervention that implements the Ariadne principles in a population of young-old patients with multimorbidity and polypharmacy. The intervention seeks to improve the appropriateness of prescribing in primary care (PC), as measured by the medication appropriateness index (MAI) score at 6 and 12months, as compared with usual care. Methods/Design: Design:pragmatic cluster randomized clinical trial. Unit of randomization: family physician (FP). Unit of analysis: patient. Scope: PC health centres in three autonomous communities: Aragon, Madrid, and Andalusia (Spain). Population: patients aged 65-74years with multimorbidity (≥3 chronic diseases) and polypharmacy (≥5 drugs prescribed in ≥3months). Sample size: n=400 (200 per study arm). Intervention: complex intervention based on the implementation of the Ariadne principles with two components: (1) FP training and (2) FP-patient interview. Outcomes: MAI score, health services use, quality of life (Euroqol 5D-5L), pharmacotherapy and adherence to treatment (Morisky-Green, Haynes-Sackett), and clinical and socio-demographic variables. Statistical analysis: primary outcome is the difference in MAI score between T0 and T1 and corresponding 95% confidence interval. Adjustment for confounding factors will be performed by multilevel analysis. All analyses will be carried out in accordance with the intention-to-treat principle. Discussion: It is essential to provide evidence concerning interventions on PC patients with polypharmacy and multimorbidity, conducted in the context of routine clinical practice, and involving young-old patients with significant potential for preventing negative health outcomes.

3 years of liraglutide versus placebo for type 2 diabetes risk reduction and weight management in individuals with prediabetes: a randomised, double-blind trial

Background: Liraglutide 3·0 mg was shown to reduce bodyweight and improve glucose metabolism after the 56-week period of this trial, one of four trials in the SCALE programme. In the 3-year assessment of the SCALE Obesity and Prediabetes trial we aimed to evaluate the proportion of individuals with prediabetes who were diagnosed with type 2 diabetes. Methods: In this randomised, double-blind, placebo-controlled trial, adults with prediabetes and a body-mass index of at least 30 kg/m2, or at least 27 kg/m2 with comorbidities, were randomised 2:1, using a telephone or web-based system, to once-daily subcutaneous liraglutide 3·0 mg or matched placebo, as an adjunct to a reduced-calorie diet and increased physical activity. Time to diabetes onset by 160 weeks was the primary outcome, evaluated in all randomised treated individuals with at least one post-baseline assessment. The trial was conducted at 191 clinical research sites in 27 countries and is registered with ClinicalTrials.gov, number NCT01272219. Findings: The study ran between June 1, 2011, and March 2, 2015. We randomly assigned 2254 patients to receive liraglutide (n=1505) or placebo (n=749). 1128 (50%) participants completed the study up to week 160, after withdrawal of 714 (47%) participants in the liraglutide group and 412 (55%) participants in the placebo group. By week 160, 26 (2%) of 1472 individuals in the liraglutide group versus 46 (6%) of 738 in the placebo group were diagnosed with diabetes while on treatment. The mean time from randomisation to diagnosis was 99 (SD 47) weeks for the 26 individuals in the liraglutide group versus 87 (47) weeks for the 46 individuals in the placebo group. Taking the different diagnosis frequencies between the treatment groups into account, the time to onset of diabetes over 160 weeks among all randomised individuals was 2·7 times longer with liraglutide than with placebo (95% CI 1·9 to 3·9, p<0·0001), corresponding with a hazard ratio of 0·21 (95% CI 0·13–0·34). Liraglutide induced greater weight loss than placebo at week 160 (–6·1 [SD 7·3] vs −1·9% [6·3]; estimated treatment difference −4·3%, 95% CI −4·9 to −3·7, p<0·0001). Serious adverse events were reported by 227 (15%) of 1501 randomised treated individuals in the liraglutide group versus 96 (13%) of 747 individuals in the placebo group. Interpretation: In this trial, we provide results for 3 years of treatment, with the limitation that withdrawn individuals were not followed up after discontinuation. Liraglutide 3·0 mg might provide health benefits in terms of reduced risk of diabetes in individuals with obesity and prediabetes. Funding: Novo Nordisk, Denmark

Guidelines for the use and interpretation of assays for monitoring autophagy (4th edition)1.

In 2008, we published the first set of guidelines for standardizing research in autophagy. Since then, this topic has received increasing attention, and many scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Thus, it is important to formulate on a regular basis updated guidelines for monitoring autophagy in different organisms. Despite numerous reviews, there continues to be confusion regarding acceptable methods to evaluate autophagy, especially in multicellular eukaryotes. Here, we present a set of guidelines for investigators to select and interpret methods to examine autophagy and related processes, and for reviewers to provide realistic and reasonable critiques of reports that are focused on these processes. These guidelines are not meant to be a dogmatic set of rules, because the appropriateness of any assay largely depends on the question being asked and the system being used. Moreover, no individual assay is perfect for every situation, calling for the use of multiple techniques to properly monitor autophagy in each experimental setting. Finally, several core components of the autophagy machinery have been implicated in distinct autophagic processes (canonical and noncanonical autophagy), implying that genetic approaches to block autophagy should rely on targeting two or more autophagy-related genes that ideally participate in distinct steps of the pathway. Along similar lines, because multiple proteins involved in autophagy also regulate other cellular pathways including apoptosis, not all of them can be used as a specific marker for bona fide autophagic responses. Here, we critically discuss current methods of assessing autophagy and the information they can, or cannot, provide. Our ultimate goal is to encourage intellectual and technical innovation in the field
