Role of age and comorbidities in mortality of patients with infective endocarditis

[Purpose]: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. [Methods]: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. [Results]: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39–1.88),and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. [Conclusion]: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group

Psychometric Properties of the Spanish Version of the Fatigue Assessment Scale in Caregivers of Palliative Care Patients

Symptoms of fatigue and lack of energy are very common in caregivers of palliative care (PC) patients, traditionally associated with variables such as burden or depression. There are no Spanish-language instruments validated for assessing fatigue levels in this population. The Fatigue Assessment Scale (FAS) is a useful and simple instrument for assessing fatigue in this group. The aim of this study was to examine its psychometric properties (factor structure, reliability and validity) in a sample of caregivers of PC patients. Instrumental design for instrument validation was performed. One hundred and eight caregivers of PC patients participated and completed measures of fatigue, family functioning, life satisfaction, caregiver burden, anxiety, depression, resilience and quality of life. A confirmatory factor analysis was performed; non-linear reliability coefficient and Pearson correlations and t-tests were conducted to assess evidence of reliability and validity. The Spanish version of the FAS was found to have a one-dimensional structure. Reliability was 0.88. Validity evidence showed that FAS scores were positively associated with levels of burden, anxiety and depression. They were negatively associated with family functioning, life satisfaction, resilience and quality of life. The Spanish version of the FAS in caregivers of PC patients shows adequate psychometric properties

Spanish adaptation of the Stillbirth Stigma Scale (SSS)

The death of a baby in the perinatal period is considered a disenfranchized grief that can be a source of significant symptoms of guilt, shame, and stigma. There is a lack of validated instruments for assessing the stigma associated with perinatal grief. The aim of this study was to examine the psychometric properties (factor structure, reliability, and validity) of the Spanish version of the Stillbirth Stigma Scale (SSS) in parents who have experienced a perinatal loss. A total of 291 participants (mostly mothers) completed an online questionnaire that included the SSS and other measures. The best-fitting factor structure was a second-order model with four dimensions and adequate reliability values. In terms of validity, we found statistically significant relationships between the SSS scores and the variables of self-esteem, complicated grief, event centrality, depression, and anxiety. In conclusion, the Spanish adaptation of the SSS is deemed to have adequate psychometric properties.This research was funded by Program Redes-I3CE for Research in University Teaching of the Institute of Education Science (Vice-Chancellorship of Quality and Educational Innovation) of the University of Alicante, edition 2020–21 [Ref. 5537]

The trophic niche breadth determines the coexistence mechanisms among carnivores in a scenario of apex predator restoration

Trabajo presentado en el 2nd Meeting of the Iberian Ecological Society (SIBECOL), celebrado en Aveiro (Portugal) del 03 al 08 de julio de 2022

Top-down and bottom-up effects modulate species co-existence in a context of top predator restoration

Mesopredators abundance is often limited by top-order predators and also by key food resources. However, the contribution of these bidirectional forces to structure carnivore community is still unclear. Here, we studied how the presence and absence of an apex predator which is currently recovering its former distribution range, the Iberian lynx (Lynx pardinus), determined the absolute abundance and fine-scale spatiotemporal avoidance mechanisms of two sympatric mesocarnivores (stone marten Martes foina and common genet Genetta genetta) with different dietary plasticity. We hypothesized that the lynx causes a mesopredator suppression and subordinate predators develop segregation strategies in respect to their trophic niche breadth. We placed 120 camera-traps in Southern Spain for 8 months in two consecutive years to estimate mesocarnivore abundances by using SCR Bayesian models, prey availability and assess spatio-temporal patterns. We found that the lynx reduced mesocarnivore abundance up to 10 times. Stone marten, a mesopredator with a broad food resources spectrum, showed a total spatial exclusion with the apex predator. Meanwhile, fine-scale avoidance mechanisms allowed the genet to persist in low density inside lynx territories, probably taking advantage of high availability of its preferred prey. Thus, the strength of these top-down and bottom-up effects was rather species-specific. Given the recent recovery of large carnivore populations worldwide, variation in suppression levels on different mesopredator species could modify ecosystem functions provided by the carnivore community in contrasting ways

Step by Step. 'Paso a paso'

Se desarrolla un proyecto de innovación educativa que trata de promoverle uso del ingles en el aula de Infantil y de Primaria, de forma natural, fluida y lo más práctica posible. Para ello se desarrollan actividades que estimulen la expresión y la comprensión oral y los procedimientos que ayuden a comunicarse en una segunda lengua. El proyecto educativo se caracteriza por tener como meta una educación bilingüe, para ello se implica parte del profesorado en una realidad social y cultural existente, y a los padres para que el proyecto tenga continuidad en el ámbito familiar. Se han utilizado juegos didácticos, puzzles, fichas de aprendizaje, murales y dibujos ilustrativos, fotografías y cuentos en ingles. En general se ha alcanzado el objetivo de introducir el bilingüismo al ámbito escolar. La participación del profesorado es total, pero donde mejores resultados se han obtenido ha sido en Educación Infantil. La evaluación ha sido continua en todas las áreas impartidas, pero sobretodo en la de lengua inglesa. El proyecto tanto en su confección, como en su desarrollo e implantación ha favorecido el trabajo en equipo, y el amor de los alumnos y alumnas a la lengua inglesa.Castilla y LeónConsejería de Educación.

Equipos docentes y nuevas identidades académicas : en educación superior

Resumen basado en el de la publicaciónLa noción de equipos docentes en Educación Superior define una práctica de coordinación docente, bien para el logro de determinados propósitos transversales, bien en un sentido mucho más estricto, en el despliegue coordinado de una Titulación. Se aborda la pregunta de por qué y sobre qué ha de coordinarse el profesorado universitario, como reto fundamental a la cultura organizativa docente, basada en el ejercicio individual del profesorado y en la fragmentación de tareas, de responsabilidades y del conocimiento. Los cambios apuntados en las diversas contribuciones obedecen a las transformaciones que se están dando en la universidad española como consecuencia de nuevas demandas socio-formativas, las cuales generan nuevas necesidades, funciones y estructuras. Ello da lugar a nuevas identidades académicas. Lo anterior, nos sitúa en un contexto interpretativo de calado más amplio, el de la reconstrucción de las identidades académicas en relación a las funciones ejercidas dentro de ella.MadridBiblioteca de Educación del Ministerio de Educación, Cultura y Deporte; Calle San Agustín 5 -3 Planta; 28014 Madrid; Tel. +34917748000; [email protected]
