Effects of dietary fiber intake on risk factors for cardiovascular disease in subjects at high risk
2009
Background: Epidemiological studies and feeding trials with supplements suggest that fibre intake is associated with a reduction in cardiovascular risk. However, the effects of changes in dietary fibre on risk factor levels have not been evaluated in free-living individuals. Thus, the effects of changes in dietary fibre intake on cardiovascular risk factors were assessed over 3 months in free-living high-risk subjects. Methods: 772 high-risk subjects (age 69±5 years) were assigned to a low-fat diet or two Mediterranean-style diets. All participants received behavioural and nutritional education, including recommendations for increasing the consumption of vegetables, fruits, and legumes. Cha…
Total and Subtypes of Dietary Fat Intake and its Association with Components of the Metabolic Syndrome in a Mediterranean Population at High Cardiova…
2019
Background: The effect of dietary fat intake on the metabolic syndrome (MetS) and in turn on cardiovascular disease (CVD) remains unclear in individuals at high CVD risk. Objective: To assess the association between fat intake and MetS components in an adult Mediterranean population at high CVD risk. Design: Baseline assessment of nutritional adequacy in participants (n = 6560, men and women, 55&ndash
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…

Búsqueda de nuevos ingredientes bioactivos en obesidad para el diseño de nuevos alimentos funcionales, en base a la demanda del consumidor
2015
La innovación tecnológica en materia de salud ha sido un campo ampliamente estudiado y sigue siendo un foco de interés económico reiterado y prioritario. La alimentación es uno de los hábitos que más repercusión tienen en el estado de salud y en la prevención de determinadas enfermedades lo que influye cada vez más en los hábitos de compra de los consumidores (Niva M., 2007, Bech-Larsen T et al., 2007, Jones PJ et al., 2007, Van Kleef E et al., 2002). Un trastorno de la alimentación puede generar obesidad y con ello el desarrollo de múltiples complicaciones asociadas a la misma. En los últimos años, la Organización Mundial de la Salud (WHO., 2014 y 2015) ha venido alertando de la gran crisi…
Risk factors for recurrence after robot-assisted radical hysterectomy for early-stage cervical cancer: a multicenter retrospective study
2020
This retrospective analysis aimed to assess the risk factors for recurrence in patients diagnosed with early-stage cervical cancer (&le
Loneliness predicts suicidal ideation and anxiety symptoms in long-term childhood cancer survivors.
2020
Abstract Background/Objective Long-term childhood cancer survivors (CCS) are at risk for adverse late effects. However, not all of them are well understood. The present study addressed loneliness, a previously under-researched mental health risk in cancer survivor populations. We assessed the prevalence of loneliness and its impact on psychological symptoms over time. Method: A registry-based sample of N = 633 adult long-term CCS underwent medical and psychological assessments and took part in a follow-up survey 2.5 years later. Psychological symptoms (somatic, anxiety, depression symptoms, and suicidal ideation) were measured using the Patient Health Questionnaire. We calculated linear reg…
Self-efficacy and perceived control in the prevention of cardiovascular disease
2010
Desde la Teoría de Acción Planeada (TAP), el objetivo de este trabajo es analizar si la autoeficacia y la percepción de control presentan diferencias predictivas sobre la intención y las conductas preventivas de la enfermedad cardiovascular. La muestra estuvo compuesta por 359 sujetos. Los datos han sido analizados empleando el paquete estadístico EQS 6.1. Los resultados muestran que la autoeficacia influye positiva y significativamente sobre la intención y sobre la conducta, mientras que la percepción de control influye negativa y significativamente sobre la intención de conducta, pero no sobre la conducta preventiva. Este trabajo ha mostrado la conveniencia de distinguir entre autoeficaci…
"Partial oxidation of methane and methanol on FeOx-, MoOx- and FeMoOx -SiO2 catalysts prepared by sol-gel method: a comparative study"
2020
[EN] FeOx-, MoOx and FeMoOx-SiO2 materials prepared by a sol-gel procedure have been evaluated as catalysts for the partial oxidation of methane and methanol. The effect of decreasing the pH of the synthesis gel on the chemical nature of FeOx and MoOx species has been investigated. Characterization results show that low pH improves the dispersion of metal oxide species present in SiO2 matrix. For FeOx/SiO2 materials, the presence of dispersed FeOx species (rather than bulk Fe2O3) improves the selectivity to formaldehyde in the partial oxidation of methane and methanol. For FeMoOx/SiOx catalysts, dispersed species favor the selectivity to formaldehyde only for methane oxidation. In contrast,…
La destitución del mito. Christa Wolf y la reescritura de la memoria histórica
2018
En este ensayo se reconstruye el recorrido narrativo de Christa Wolf desde una perspectiva que propongo definir como destitución mitológica. Se fijan cuatro estaciones correspondientes con las cuatro novelas cruciales en la biografía literaria de la autora. La primera es El cielo partido, en la que Wolf trabaja con el concepto de Vergangenheitsbewältigung, es decir: una elaboración del pasado que permite su superación. La segunda es Muestra de infancia, en la que aparece la figura de la precisión fantástica, entendida como la única auténtica posibilidad de memoria histórica colectiva. Finalmente Casandra y Medea, donde este trabajo de rememoración encuentra su aplicación en la deconstrucció…
