Cardiovascular Events During and After Bronchiectasis Exacerbations and Long-term Mortality.
2022
ABSTRACT Background Population-based and retrospective studies have shown that risk for cardiovascular events such as arrythmias, ischemic episodes or heart failure, increase during and after bronchiectasis exacerbations. Research Question What are the risk factors for cardiovascular events (CVE) during and after bronchiectasis exacerbations and its impact on mortality? Study Design and Methods This was a post-hoc retrospective analysis of a prospective observational study of 250 patients with bronchiectasis at two tertiary care hospitals. Only the first exacerbation was considered for each patient, collecting demographic, comorbidity, and severity data. The main outcomes were the appearanc…
Tabaquismo en sanitarios. Identificación de factores asociados
1998
The objective of this study was to determine the epidemiology of smoking among health care givers in our setting and to describe their characteristics. We gave an anonymous questionnaire to 566 health care workers in the Valencian Community (248 physicians, 212 nurses and 106 aides). The results were as follows. Physicians: 46.4% were smokers, 25.4% were non smokers and 28.2% were ex-smokers. Most (69.3%) smoked 11 to 20 cigarettes/day. Low scores on Fagerstrom's test were recorded for 93%, and 57.3% have tried to quit smoking more than 5 times. The likelihood of being and ex-smoker increased with age (r = 0.158; p = 0.012) and with the number of attempts to quit (r = 0.170; p = 0.021). Nur…
Irreducible characters taking root of unity values on $p$-singular elements

In this paper we study finite p-solvable groups having irreducible complex characters chi in Irr(G) which take roots of unity values on the p-singular elements of G.

Amyloid Beta-Mediated Changes in Synaptic Function and Spine Number of Neocortical Neurons Depend on NMDA Receptors
2021
Onset and progression of Alzheimer’s disease (AD) pathophysiology differs between brain regions. The neocortex, for example, is a brain region that is affected very early during AD. NMDA receptors (NMDARs) are involved in mediating amyloid beta (Aβ) toxicity. NMDAR expression, on the other hand, can be affected by Aβ. We tested whether the high vulnerability of neocortical neurons for Aβ-toxicity may result from specific NMDAR expression profiles or from a particular regulation of NMDAR expression by Aβ. Electrophysiological analyses suggested that pyramidal cells of 6-months-old wildtype mice express mostly GluN1/GluN2A NMDARs. While synaptic NMDAR-mediated currents are unaltered in 5xFAD …
Acoso escolar y Educación Física: una revisión sistemática (Bullying in schools and Physical Education: A systematic review)
2018
El objetivo de este trabajo es realizar una revisión sistemática de estudios sobre acoso escolar y Educación Física (EF). Se identifican, categorizan y analizan los artículos señalando sus características y sintetizando los principales temas de investigación y su contenido. Para ello, se ha consultado la base de datos Web of Science®. Se seleccionaron un total de 19 artículos científicos. Respecto al análisis documental, se presentan hallazgos sobre revistas más productivas, autores e instituciones con mayor actividad investigadora en este campo y metodología de investigación utilizada en los estudios encontrados. Además, se hace un análisis cualitativo centrado en el contenido de los 4 tem…
Valoración de un programa piloto de prescripción de actividad física en atención primaria en la Comunitat Valenciana
2021
Resumen: Objetivo: Valorar el proceso de prescripción y la mejora de la autoestima y la calidad de vida relacionada con la salud en un estudio piloto de prescripción de activos de actividad física durante 3 meses. Método: Estudio cuasiexperimental antes-después sin grupo control, para la valoración del proyecto piloto (noviembre de 2017 y mayo de 2018) del programa Conecta Actius per a la Salut en seis centros de salud de la Comunitat Valenciana. Quienes aceptaron participar cumplimentaron un cuestionario con datos sociales, la escala de autoestima de Rosemberg y el cuestionario de calidad de vida EQ-5D al inicio (T0) y a los 3 meses (T1). Se realizó un análisis descriptivo por sexo, nivel …
New active drugs against liver stages of Plasmodium predicted by molecular topology.
2008
ABSTRACT We conducted a quantitative structure-activity relationship (QSAR) study based on a database of 127 compounds previously tested against the liver stage of Plasmodium yoelii in order to develop a model capable of predicting the in vitro antimalarial activities of new compounds. Topological indices were used as structural descriptors, and their relation to antimalarial activity was determined by using linear discriminant analysis. A topological model consisting of two discriminant functions was created. The first function discriminated between active and inactive compounds, and the second identified the most active among the active compounds. The model was then applied sequentially t…
Infection risks of city canal swimming events in the Netherlands in 2016.
2018
Introduction Swimming events in city canals are gaining popularity in the Netherlands, even though canal water is usually not officially designated for recreational use. Knowledge regarding the risk of infection after swimming in canals is limited. An outbreak was reported in 2015 following a canal swimming event in Utrecht, the Netherlands. Local governments were concerned about the health risks of such events. In order to assess the safety of canal swimming, the Public Health Service (PHS) prospectively investigated two city canal swimming events in 2015. In 2016, we repeated this study, aiming to prospectively determine the risks of infection during two urban swimming events, the Utrecht…
The Ghost of the Hawk: Top Predator Shaping Bird Communities in Space and Time
2021
Despite the wide recognition that strongly interacting species can influence distributions of other species, species interactions are often disregarded when assessing or projecting biodiversity distributions. In particular, it remains largely uncharted the extent to which the disappearance of a keystone species cast repercussions in the species composition of future communities. We tested whether an avian top predator can exert both positive and negative effects on spatial distribution of other species, and if these effects persist even after the predator disappeared. We acquired bird count data at different distances from occupied and non-occupied nests of Northern goshawks Accipiter genti…
