          Abstract

          Introduction: The high prevalence of metabolic syndrome (MS) in Spain requires additional efforts for prevention and treatment. Objective: The study RESMENA-S aims to improve clinical criteria and biomarkers associated with MS though an integral therapy approach. Methods: The study is a randomized prospective parallel design in which is expected to participate a total of 100 individuals. The RESMENA-S group (n = 50) is a personalized weight loss (30% energy restriction) diet, with a macronutrient distribution (carbohydrate / fat / protein) of 40/30/30, high meal frequency (7 / day), low glycemic index/load and high antioxidant capacity as well as a high adherence to the Mediterranean diet. The control group (n = 50) is assigned to a diet with the same energy restriction and based on the American Heart Association pattern. Both experimental groups are under dietary and psychological control during 8 weeks. Likewise, for an additional period of 16 weeks of self-control, is expected that volunteers will follow the same pattern but with no dietary advice. Results: Anthropometrical data and body composition determinations as well as blood and urine samples are being collected at the beginning and end of each phase. This project is registered at www.clinicaltrials.gov with the number NCT01087086 and count with the Research Ethics Committee of the University of Navarra approval (065/2009). Conclusions: Intervention trials to promote the adoption of dietary patterns and healthy lifestyle are of great importance to identify the outcomes and nutritional mechanisms that might explain the link between obesity, metabolic syndrome and associated complications.

          Introducción: La alta prevalencia del síndrome metabólico (SM) en España requiere de esfuerzos adicionales para su prevención y tratamiento. Objetivo: El estudio RESMENA-S tiene como objetivo mejorar criterios clínicos de SM y biomarcadores asociados a través de un tratamiento integral. Métodos: El estudio consiste en un ensayo aleatorizado de diseño paralelo y prospectivo en el que está previsto participen un total de 100 individuos. El grupo RESMENA-S (n = 50) sigue una dieta personalizada de pérdida de peso (restricción energética 30%), con una distribución en macronutrientes (hidratos de carbono/grasas/ proteínas) de 40/30/30, elevada frecuencia de ingestas (7/día), bajo índice/carga glucémica y elevada capacidad antioxidante y adherencia a la dieta Mediterránea. El grupo control (n = 50) sigue una dieta con la misma restricción energética y basada en la Asociación Americana del Corazón. El estudio tiene una duración de 8 semanas bajo control dietético y psicológico en ambos grupos. Durante un periodo adicional de 16 semanas de auto-control, los voluntarios siguen el mismo patrón dietético pero sin ningún asesoramiento específico. Resultados: Datos antropométricos y de composición corporal, así como muestras sanguíneas y de orina están siendo recogidas al inicio y al final de cada fase. Este proyecto está registrado en www.clinicaltrials.gov con el número NCT01087086 y cuenta con la aprobación del Comité de Ética de Investigación de la Universidad de Navarra (065/2009). Conclusiones: Las intervenciones que favorezcan la adopción de patrones dietéticos y de estilo de vida más saludables, son de elevada importancia para identificar los mecanismos que podrían explicar el nexo de unión entre obesidad, SM y complicaciones asociadas.

          Mass-spectrometry-based metabolomics: limitations and recommendations for future progress with particular focus on nutrition research

          Mass spectrometry (MS) techniques, because of their sensitivity and selectivity, have become methods of choice to characterize the human metabolome and MS-based metabolomics is increasingly used to characterize the complex metabolic effects of nutrients or foods. However progress is still hampered by many unsolved problems and most notably the lack of well established and standardized methods or procedures, and the difficulties still met in the identification of the metabolites influenced by a given nutritional intervention. The purpose of this paper is to review the main obstacles limiting progress and to make recommendations to overcome them. Propositions are made to improve the mode of collection and preparation of biological samples, the coverage and quality of mass spectrometry analyses, the extraction and exploitation of the raw data, the identification of the metabolites and the biological interpretation of the results.

            Anti-inflammatory effects of the Mediterranean diet: the experience of the PREDIMED study.

            Several epidemiological and clinical studies have evaluated the effects of a Mediterranean diet (Med-Diet) on total cardiovascular mortality, and all concluded that adherence to the traditional Med-Diet is associated with reduced cardiovascular risk. However, the molecular mechanisms involved are not fully understood. Since atherosclerosis is nowadays considered a low-grade inflammatory disease, recent studies have explored the anti-inflammatory effects of a Med-Diet intervention on serum and cellular biomarkers related to atherosclerosis. In a pilot study of the PREvencion con DIeta MEDiterranea (PREDIMED) trial, we analysed the short-term effects of two Med-Diet interventions, one supplemented with virgin olive oil and another with nuts, on vascular risk factors in 772 subjects at high risk for CVD, and in a second study we evaluated the effects of these interventions on cellular and serum inflammatory biomarkers in 106 high-risk subjects. Compared to a low-fat diet, the Med-Diet produced favourable changes in all risk factors. Thus, participants in both Med-Diet groups reduced blood pressure, improved lipid profile and diminished insulin resistance compared to those allocated a low-fat diet. In addition, the Med-Diet supplemented with virgin olive oil or nuts showed an anti-inflammatory effect reducing serum C-reactive protein, IL-6 and endothelial and monocytary adhesion molecules and chemokines, whereas these parameters increased after the low-fat diet intervention. In conclusion, Med-Diets down-regulate cellular and circulating inflammatory biomarkers related to atherogenesis in subjects at high cardiovascular risk. These results support the recommendation of the Med-Diet as a useful tool against CVD.

              Psychometric properties of the State-Trait Inventory for Cognitive and Somatic Anxiety (STICSA): comparison to the State-Trait Anxiety Inventory (STAI).

              The State-Trait Inventory for Cognitive and Somatic Anxiety (STICSA; M. J. Ree, C. MacLeod, D. French, & V. Locke, 2000) was designed to assess cognitive and somatic symptoms of anxiety as they pertain to one's mood in the moment (state) and in general (trait). This study extended the previous psychometric findings to a clinical sample and validated the STICSA against a well-published measure of anxiety, the State-Trait Anxiety Inventory (STAI; C. D. Spielberger, 1983). Patients (N=567) at an anxiety disorders clinic were administered a battery of questionnaires. The results of confirmatory factor analyses (Bentler-Bonnett nonnormed fit index, comparative fit index, and Bollen fit index>.90; root-mean-square error of approximation /=.64), the STICSA was more strongly correlated with another measure of anxiety (rs>/=.67) and was less strongly correlated with a measure of depression (rs
