Effect of the Mediterranean diet and probiotic supplementation in the management of mild cognitive impairment: Rationale, methods, and baseline characteristics.

Introduction: Mild cognitive impairment (MCI) can progress to Alzheimer's disease (AD). When MCI is not properly controlled, the speed of deterioration can dramatically increase. Reduction of oxidative stress/inflammation and the modulation of the could be new potential therapeutic targets for the prevention and treatment of AD.

Biological senescence risk score. A practical tool to predict biological senescence status.

Background: Ageing and biological senescence, both related to cardiovascular disease, are mediated by oxidative stress and inflammation. We aim to develop a predictive tool to evaluate the degree of biological senescence in coronary patients.

Methods: Relative telomere length (RTL) of 1002 coronary patients from the CORDIOPREV study (NCT00924937) was determined at baseline in addition to markers of inflammatory response (hs-C-Reactive Protein, monocyte chemoattractant protein-1, IL-6, IL-1β, TNF-α, adiponectin, resistin and leptin) and oxidative stress (nitric oxide, lipid peroxidation products, carbonylated proteins, catalase, total glutathione, reduced glutathione, oxidized glutathione, superoxide dismutase and peroxidated glutathione).

Gut microbiota and aging-A focus on centenarians.

Gut microbiota (GM) is a dynamic organ throughout the lifespan. Aging is a complex process that comprises a plethora of mechanisms such as senescence, immunosenescence and inflammaging, representing important pathways of age-related diseases. GM structure could both influence and be influenced by aging occurring changes within the host.

Effects of Aging and Diet on Cardioprotection and Cardiometabolic Risk Markers.

The prevalence of several diseases increases by age, including cardiovascular diseases, which are the leading cause of morbidity and mortality worldwide. Aging, as a complex process characterized by senescence, triggers various pathways, such as oxidative stress, systemic inflammation, metabolism dysfunction, telomere shortening, mitochondrial dysfunction and deregulated autophagy. A better understanding of the mechanisms underlying senescence may lead to the development of new therapeutic targets and strategies for age-related pathologies and extend the healthy lifespan.

Long-term dietary adherence and changes in dietary intake in coronary patients after intervention with a Mediterranean diet or a low-fat diet: the CORDIOPREV randomized trial.

Purpose: Adherence to a healthy dietary pattern positively influences clinical outcomes in cardiovascular prevention, but long-term adherence is difficult to maintain. We evaluated 5-year changes in dietary habits, adherence achieved, and its maintenance in a cohort of coronary patients from the CORDIOPREV study.

Methods: 1002 coronary patients were randomized to a Mediterranean diet (n = 502) or a low-fat diet (n = 500) and received individual-group-telephone visits and personalized dietary advice.

Gut Microbiota, Obesity and Bariatric Surgery: Current Knowledge and Future Perspectives.

Background: There is an urgent need for a better understanding and management of obesity and obesity- associated diseases. It is known that obesity is associated with structural and functional changes in the microbiome.

Methods: The purpose of this review is to present current evidence from animal and human studies, demonstrating the effects and the potential efficacy of microbiota modulation in improving obesity and associated metabolic dysfunctions.

Low Intake of Vitamin E Accelerates Cellular Aging in Patients With Established Cardiovascular Disease: The CORDIOPREV Study.

Leukocyte telomere length (LTL) shortening is a biomarker of cellular aging that can be decelerated by diet. We aimed to investigate the effect of dietary intake of vitamin E on biomarkers of cellular senescence in patients with established cardiovascular disease. To this end, DNA from 1,002 participants of the CORDIOPREV study (NCT00924937) was isolated and LTL was measured by real-time PCR.

Telomerase RNA Component Genetic Variants Interact With the Mediterranean Diet Modifying the Inflammatory Status and its Relationship With Aging: CORDIOPREV Study.

Background: Leukocyte telomere length (LTL) attrition has been associated with age-related diseases. Telomerase RNA Component (TERC) genetic variants have been associated with LTL; whereas fatty acids (FAs) can interact with genetic factors and influence in aging. We explore whether variability at the TERC gene locus interacts with FA profile and two healthy diets (low-fat diet vs Mediterranean diet [MedDiet]) modulating LTL, glucose metabolism, and inflammation status in coronary heart disease (CHD) patients.

TNFA gene variants related to the inflammatory status and its association with cellular aging: From the CORDIOPREV study.

Background: Several single nucleotide polymorphisms have been proposed as potential predictors of the development of age-related diseases.

Objective: To explore whether Tumor Necrosis Factor Alpha (TNFA) gene variants were associated with inflammatory status, thus facilitating the rate of telomere shortening and its relation to cellular aging in a population with established cardiovascular disease from the CORDIOPREV study (NCT00924937).

Materials And Methods: SNPs (rs1800629 and rs1799964) located at the TNFA gene were genotyped by OpenArray platform in 840 subjects with established cardiovascular disease.
