Leisure-time physical activity, sedentary behaviors, sleep, and cardiometabolic risk factors at baseline in the PREDIMED-PLUS intervention trial: A c…
2017
Limited data exists on the interrelationships between physical activity (PA), sedentary behaviors and sleep concerning cardiometabolic risk factors in aged adults at high cardiovascular disease risk. Our aim was to examine independent and joint associations between time spent in leisure-time PA, sedentary behaviors and sleep on the prevalence of obesity, type 2 diabetes (T2D) and components of the metabolic syndrome (MetS) in Mediterranean individuals at high cardiovascular risk. Cross-sectional analyses were performed on baseline data from 5776 Spanish adults (aged 55-75y in men; 60-75y in women) with overweight/ obesity and MetS, from October 2013 to October 2016, in the PREDIMED-PLUS tri…
Una revisión de los sistemas generadores y modelos de probabilidad descriptivos de la distribución de la Renta
2000
La importancia innegable de la modelización de la distribución de la renta es el origen del presente trabajo en el que se realiza un estudio, básicamente teórico, acerca de los sistemas generadores de renta y se lleva a cabo una recopilación de los modelos de probabilidad que se han utilizado, de forma más o menos generalizada a lo largo del último siglo, para explicar la renta. El estudio realizado es más exhaustivo en unos casos que en otros, poniendo de manifiesto el carácter pionero de la distribución de Pareto, y analizando en muchos de los casos las medidas más importantes de las distribuciones estudiadas, así como la relación de algún parámetro de las mismas con la desigualdad en el …
Creer que p. Consideraciones en torno a la creencia
2012
This article is intended as a contribution to our understanding of the nature of belief as a propositional attitude. After contextualizing the issue, we discuss and reject some accounts of belief as a gamble and as high (near to 1) subjective probability and argue for the claim that believing that p consists in merely attributing a higher subjective probability to p than to not-p being not-p any of p"s alternatives and all of them as a whole. Additionally, we propose that the question which a belief answers is crucial in order to determine the degree of belief and the reasons in its favor. Este artículo trata de profundizar en nuestra comprensión de la naturaleza de la creencia en tanto que…
La simulació en l’aprenentatge de la probabilitat en primària
2013
El present treball pretén fer un estudi exploratori de les possibilitats que ens ofereix la simulació com a mètode de resolució de problemes de probabilitat en l’aprenentatge de la probabilitat i l’estadística a l’educació primària. En la seua aplicació es planteja l’elaboració d’una unitat didàctica basada en la resolució de problemes i es mostren els resultats de l’aplicació d’aquesta a una aula de sisé de primària. In this report we intend to do an exploratory study of the possibilities offered by the simulation as a method for solving probability problems in the learning of probability and statistics in primary education. In its application it is planned to develop a teaching unit based…
Efectos de las enfermedades de las mujeres sobre resultados FIV/ICSI y la utilización de probabilidades acumuladas de nacimiento vivo como único méto…
2020
La presente tesis doctoral está estructurada en tres capítulos distintos. El primer capítulo tiene como objetivo determinar si existe una relación causal entre las enfermedades de las mujeres presentes al inicio del primer ciclo de recuperación de ovocitos y los resultados de fecundación in vitro (FIV)/inyección intracitoplasmática de un espermatozoide (ICSI), principalmente, la probabilidad de tener un nacimiento vivo en el primer ciclo de tratamiento FIV/ICSI. La conclusión de este apartado indica que existe una asociación causal significativa entre la mayoría de las enfermedades preexistentes o concomitantes en el momento de iniciar el primer ciclo de recuperación de ovocitos y una menor…
Associations of the FTO rs9939609 and the MC4R rs17782313 polymorphisms with type 2 diabetes are modulated by diet, being higher when adherence to th…
2012
Background: Although the Fat Mass and Obesity (FTO) and Melanocortin-4 Receptor (MC4R) genes have been consistently associated with obesity risk, the association between the obesity-risk alleles with type 2 diabetes is still controversial. In some recent meta-analyses in which significant results have been reported, the associations disappeared after adjustment for body mass index (BMI). However gene-diet interactions with dietary patterns have not been investigated. Our main aim was to analyze whether these associations are modulated by the level of adherence to the Mediterranean Diet (MedDiet). Methods: Case-control study in 7,052 high cardiovascular risk subjects (3,430 type 2 diabetes c…
Mercury exposure and risk of cardiovascular disease: a nested case-control study in the PREDIMED (PREvention with MEDiterranean Diet) study
2017
Background: Substantial evidence suggests that consuming 1-2 servings of fish per week, particularly oily fish (e.g., salmon, herring, sardines) is beneficial for cardiovascular health due to its high n-3 polyunsaturated fatty acid content. However, there is some concern that the mercury content in fish may increase cardiovascular disease risk, but this relationship remains unclear. Methods: The PREDIMED trial included 7477 participants who were at high risk for cardiovascular disease at baseline. In this study, we evaluated associations between mercury exposure, fish consumption and cardiovascular disease. We randomly selected 147 of the 288 cases diagnosed with cardiovascular disease duri…
C14 y poblamiento en las comarcas centro-meridionales del País Valenciano (c. 7000-1500 cal BC).
2018
Las comarcas centro-meridionales del País Valenciano y sus cuencas fluviales constituyen áreas con documentación excelente de la Prehistoria Reciente, gracias al interés continuado de la investigación desde el s. XIX hasta hoy. En este trabajo, presentamos un análisis combinado de series de fechas C14 junto con datos relativos al poblamiento, para comprender mejor la dinámica local desde el Mesolítico a la Edad de Bronce. Palabras clave: radiocarbono; poblamiento; sumatorios de probabilidad; Prehistoria Reciente.
Blood pressure values and depression in hypertensive individuals at high cardiovascular risk
2014
Background: Hypertension and depression are both important risk factors for cardiovascular diseases. Nevertheless, the association of blood pressure on and depression has not been completely established. This study aims to analyze whether depression may influence the control of blood pressure in hypertensive individuals at high cardiovascular risk. Methods: Cross-sectional study, embedded within the PREDIMED clinical trial, of 5954 hypertensive patients with high cardiovascular risk factor profiles. The relationship between blood pressure control and depression was analyzed. A multivariate analysis (logistic and log-linear regression), adjusting for potential confounders (socio-demographic …
