    Abstract: Introduction: GlycA is a novel biomarker of systemic inflammation and cardiovasculardisease (CVD) risk. It is measured by a signal in the proton nuclear magnetic resonance(NMR) spectra (from the N-acetyl methyl groups of N-acetylglucosamine residues).Epidemiological studies have reported associations between GlycA and increased CVD risk.However, there are few investigations examining the link between GlycA levels and lifestylefactors (diet, physical activity (PA), sleep, etc.), gut microbiota, or genetics at the genome-wide level (GWAS); and even fewer studies have analyzed serum GlycA and genome-widemethylation (EWAS) or the effect of lifestyle intervention on the reduction of GlycA.Therefore, our aims were: i) to investigate lifestyle, genetic, and epigenetic factorsassociated with serum GlycA; ii) to examine changes in serum GlycA after 1-y lifestyleintervention in a Mediterranean population. Methods: Cross-sectional and lifestyleintervention analyses were undertaken in a Mediterranean population at highcardiovascular risk (n=426 older subjects with metabolic syndrome in the PREDIMED-Plus-Valencia trial; ISRCTN89898870). Lifestyle variables were assessed by validatedquestionnaire and quantile-g-computation methods were used to analyze their jointcontribution. Serum GlycA was measured by NMR spectroscopy. Genome-wide genotypingand DNA-methylation were determined by Illumina arrays (OmniExpress and EPIC).Exploratory omics-wide and targeted analyses on GlycA (focusing on autophagy genes andmicrobiome-host-related genes) were undertaken. Changes in serum GlycA levels after a 1-y lifestyle intervention (intensive intervention group with Mediterranean diet and PA versusthe control group) were assessed in a subset of participants. Results: GlycA levels atbaseline (Mean: 1.49+/-0.20 mmol/L) were significantly associated with branched-chainamino acids and a highly atherogenic lipid profile. Also, we obtained an association withdietary factors and PA. Omics analysis suggested novel SNPs (in SFMBT2- DAB1 and TEK)and methylation sites (CpG in RAD50, PPP1R9B, ZDHHC4 and LSP1) associated with GlycA. We also obtained associations with host-microbiome related SNPs in FUT2 and withmethylation signals in selected autophagy genes (STX7, TAX1BP1, ATG9B and ATG10).Moreover, in the intervention trial we detected a significant (P 〈 0.05) decrease in the GlycAlevels after 1 y of intensive lifestyle intervention in comparison with the control group. Conclusions: Serum GlycA levels were strongly associated with cardiometabolic risk factorsin this Mediterranean population and linked to lifestyle variables. Additionally, we haveidentified some genetic and epigenetic factors related to GlycA that may modulate theselevels.

    Abstract: Background: The aim of this study was to determine if long-term adherence to a prescribed diet, in the context of the PREDIMED trial, a multi-year, randomized, controlled trial, was different among obese and non-obese participants after an average follow-up of three years. Previous studies only examined short term compliance or were not sufficiently powered to compare obese with nonobese participants. Methods: This randomized clinical trial included 6,463 subjects. All subjects were asymptomatic; females aged 55-80 years and males 55-80 years and were at high-risk for cardiovascular disease at baseline. Participants’ characteristics were measured at baseline and every 12 months. Obesity was defined as having a BMI of 30kg/m2 or more. The main outcome measure was achieving an average score of 10 points or more on a validated 14-point Mediterranean diet adherence scale over follow-up. Results: In all three dietary intervention groups, obesity status was significantly inversely associated with adherence to the Mediterranean diet; In the olive oil group, the odds ratio of obtaining a score of 10 or more was 23.4% (95% CI: 6.3, 37.5%) lower for obese subjects than for non-obese subjects after an average follow-up of three years. A similar pattern was also seen in the nuts group; the odds of obtaining a score of 10 or more was 24.3% (95% CI: 5.1,39.6%) lower for obese subjects than for non-obese subjects. In the low fat group, subjects who were obese at baseline had 25.7% (95% CI:5.7, 40.8%) lower odds of obtaining a score of 10 or more on the adherence score. All models were adjusted for relevant covariates. Conclusion: In this long-term trial of the Mediterranean Diet, adherence was high across all intervention groups. However, adherence was appreciably lower among obese participants after three years. Additional intervention efforts may be necessary to achieve the same adherence among high-risk obese individuals.

    Abstract: The PREvención con DIeta MEDiterránea (PREDIMED) trial showed that Mediterranean diets (MedDiets) supplemented with either extravirgin olive oil or nuts reduced cardiovascular events, particularly stroke, compared with a control, lower fat diet. The mechanisms of cardiovascular protection remain unclear. We evaluated the 1-year effects of supplemented MedDiets on 24-hour ambulatory blood pressure (BP), blood glucose, and lipids. Randomized, parallel-design, controlled trial was conducted in 2 PREDIMED sites. Diets were ad libitum, and no advice on increasing physical activity or reducing sodium intake was given. Participants were 235 subjects (56.5% women; mean age, 66.5 years) at high cardiovascular risk (85.4% with hypertension). Adjusted changes from baseline in mean systolic BP were −2.3 (95% confidence interval [CI], −4.0 to −0.5) mm Hg and −2.6 (95% CI, −4.3 to −0.9) mm Hg in the MedDiets with olive oil and the MedDiets with nuts, respectively, and 1.7 (95% CI, −0.1 to 3.5) mm Hg in the control group ( P 〈 0.001). Respective changes in mean diastolic BP were −1.2 (95% CI, −2.2 to −0.2), −1.2 (95% CI, −2.2 to −0.2), and 0.7 (95% CI, −0.4 to 1.7) mm Hg ( P =0.017). Daytime and nighttime BP followed similar patterns. Mean changes from baseline in fasting blood glucose were −6.1, −4.6, and 3.5 mg/dL ( P =0.016) in the MedDiets with olive oil, MedDiets with nuts, and control diet, respectively; those of total cholesterol were −11.3, −13.6, and −4.4 mg/dL ( P =0.043), respectively. In high-risk individuals, most with treated hypertension, MedDiets supplemented with extravirgin olive oil or nuts reduced 24-hour ambulatory BP, total cholesterol, and fasting glucose.

    Abstract: Background: Metabolites associated with betaine and choline metabolism and the gut-microbiota-dependent metabolite trimethylamine N-oxide (TMAO) have been linked to the risk of cardiovascular disease (CVD). However, the relationship between plasma concentrations of other gut microbiota-related metabolites and major CVD endpoints remains unclear. Objectives: To evaluate the association between gut microbiota-related metabolites and risk of incident CVD and the potential modifying effect of Mediterranean diet (MedDiet) interventions. Methods: We designed a case-cohort study nested within the PREDIMED trial. We used liquid chromatography–tandem mass spectrometry to measure plasma gut microbiota-related metabolites. A score including the sum of quartile values of 8 metabolites was constructed (TMAO, betaine, choline, phosphocholine, alphaglycerophosphocholine, proline, hydroxyproline, allantoin). The primary outcome was a composite of myocardial infarction, stroke, and cardiovascular death. Blood samples from a randomly selected PREDIMED sub-cohort (n=751) and all available incident CVD cases (n=229) after 4.8-y of follow-up were included in the analysis. We used weighted Cox regression models to estimate multivariable-adjusted hazard ratios (HR) and their 95% confidence intervals (CI). Models were adjusted for age, sex, BMI, family history of premature heart disease, and smoking, physical activity (metabolic equivalent tasks in min/d), hypertension, dyslipidemia, diabetes and was stratified by intervention group. Results: Baseline plasma concentrations of choline and hydroxyproline were associated with higher CVD risk independent of traditional risk factors, while no significant association between plasma concentrations of TMAO and CVD was found. The HRs comparing extreme quartiles (lowest quartile as the reference) were 1.72 (95% CI: 1.05, 2.81; P for trend=0.01) and 1.65 (95% CI: 1.03, 2.65; P for trend =0.04), respectively. The microbiota metabolite score was associated with a 2.13-fold higher risk of CVD across extreme quartiles (95% CI: 1.32, 3.43; P for trend 〈 0.001) and a 1.99-fold higher risk of stroke (95% CI: 1.08, 3.65; P for trend=0.02). Baseline betaine/choline ratio was inversely associated with CVD. Compared to participants with a score below the median and randomized to the Mediterranean diet, the HR of developing CVD was 2.56 (95% CI: 1.59, 4.11) for participants with a gut microbiota score above the median and randomized to the control group. Conclusions: Plasma gut microbiota-related metabolites were associated with an increased risk of CVD in a Mediterranean population at high cardiovascular risk, independent of traditional CVD risk factors.

    Abstract: The Prevención con Dieta Mediterránea (PREDIMED) trial showed that a Mediterranean diet (MedDiet) supplemented with either extra virgin olive oil or 30 g/d of mixed nuts reduced incident cardiovascular events compared with a control (low fat) diet. The mechanisms of cardiovascular protection afforded by MedDiets remain to be uncovered. We assessed the effect of both supplemented MedDiets on internal carotid intima-media thickness (ICA-IMT) and plaque height, the ultrasound features that best predict future cardiovascular events, in subjects at high cardiovascular risk. Approach and Results— In a PREDIMED subcohort (n=175), plaque height and carotid IMT of 3 prespecified segments (ICA, bifurcation, and common) were sonographically assessed at baseline and after intervention for a mean of 2.4 years. We evaluated 164 subjects with complete data. In a multivariate model, mean ICA-IMT progressed in the control diet group (mean [95% confidence interval], 0.052 mm [−0.014 to 0.118 mm] ), whereas it regressed in the MedDiet+nuts group (−0.084 mm [−0.158 to −0.010 mm]; P =0.024 versus control). Similar results were observed for maximum ICA-IMT (control, 0.188 mm [0.077 to 0.299 mm]; MedDiet+nuts, −0.030 mm [−0.153 to 0.093 mm] ; P =0.034) and maximum plaque height (control, 0.106 mm [0.001 to 0.210 mm]; MedDiet+nuts, −0.091 mm [−0.206 to 0.023 mm] ; P =0.047). There were no changes in ICA-IMT or plaque after the MedDiet+extra virgin olive oil. Conclusions— Compared with a control diet, consumption of a MedDiet supplemented with nuts is associated with delayed progression of ICA-IMT and plaque. The results contribute mechanistic evidence for the reduction of cardiovascular events observed in the PREDIMED trial. Clinical Trial Registration— URL: http://www.controlled-trials.com .

    Abstract: The PREDIMED (Prevención con Dieta Mediterránea) primary prevention trial showed that a Mediterranean diet enriched with either extravirgin olive oil or mixed nuts reduces the incidence of stroke, myocardial infarction, and cardiovascular mortality. We assessed the effect of these diets on the incidence of atrial fibrillation in the PREDIMED trial. Methods and Results— Participants were randomly assigned to 1 of 3 diets: Mediterranean diet supplemented with extravirgin olive oil, Mediterranean diet supplemented with mixed nuts, or advice to follow a low-fat diet (control group). Some departures from individual randomization occurred in a subset of the trial because members of the same household and small clinics in one of the 11 recruiting centers were allocated by clusters instead of individually. Incident atrial fibrillation was adjudicated during follow-up by an events committee blinded to dietary group allocation. Among 6705 participants without prevalent atrial fibrillation at randomization, we observed 72 new cases of atrial fibrillation in the Mediterranean diet with extravirgin olive oil group, 92 in the Mediterranean diet with mixed nuts group, and 89 in the control group after median follow-up of 4.7 years. The Mediterranean diet with extravirgin olive oil significantly reduced the risk of atrial fibrillation (hazard ratio, 0.62; 95% confidence interval, 0.45–0.86 compared with the control group) after adjusting for propensity scores and using robust variance estimators to account for the intra-cluster correlations. No effect was found for the Mediterranean diet with nuts (hazard ratio, 0.86; 95% confidence interval, 0.63–1.16). In secondary analyses done after excluding all participants randomized in clusters, the results did not materially change. Conclusions— In the absence of proven interventions for the primary prevention of atrial fibrillation, this post hoc analysis of the PREDIMED trial suggests that a lower incidence of atrial fibrillation was found after an intervention with extravirgin olive oil in the context of a Mediterranean dietary pattern.

    Abstract: Objectives: To assess the association between potato consumption, blood pressure changes and the risk of hypertension in two Mediterranean populations. Design: Separate analyses were performed in the PREDIMED (PREvención con DIeta MEDiterránea), a multicenter nutrition intervention trial, and the SUN (“Seguimiento Universidad de Navarra”) project, an open, prospective cohort, both in Spain. Participants: The PREDIMED trial included 6,940 participants aged 55-80 years at high risk for cardiovascular disease. The SUN project included 13,837 middle-aged participants who were university graduates. Main outcome measures: In PREDIMED, generalized estimating equations adjusted for lifestyle and dietary characteristics were used to assess changes in blood pressure across quintiles of total potato consumption during a 4-year follow-up. Controlled blood pressure levels during follow-up were also assessed. For SUN, multivariable-adjusted hazard ratios (HR) for incident hypertension during an average 6.7-year follow-up were calculated. Results: In PREDIMED, the mean (SD) total potato intake was 81.9 (40.6) g/day. No overall significant differences in blood pressure changes were detected based on consumption of potatoes. For total potatoes, the mean change in systolic BP after multivariate adjustment was quintile 5 (Q5) vs. quintile 1 (Q1): -0.90, 95% CI: (-2.56 to 0.76) mmHg, p for trend=0.14 and for diastolic BP it was Q5 vs. Q1: -0.02, 95% CI: (-0.93 to 0.89) mmHg, p for trend=0.81. In SUN, the mean (SD) total potato consumption was 52.7 (33.6) g/day and no significant association between potato consumption and hypertension incidence was observed: HR: for total potato consumption, Q5 vs. Q1: 0.98, 95% CI: (0.80 to 1.19), p for trend=0.84. Conclusions: Potato consumption is not associated with changes in blood pressure or risk of hypertension in Mediterranean populations and this might be explained by relatively low consumption of potatoes and characteristics of the traditional Mediterranean diet, particularly the custom of accompanying potatoes with vegetables or legumes and dressing them with olive oil.

    Abstract: A variant (rs3812316, C771G, and Gln241His) in the MLXIPL (Max-like protein X interacting protein-like) gene encoding the carbohydrate response element binding protein has been associated with lower triglycerides. However, its association with cardiovascular diseases and gene–diet interactions modulating these traits are unknown. Methods and Results— We studied 7166 participants in the PREvención with DIeta MEDiterránea trial testing a Mediterranean diet (MedDiet) intervention versus a control diet for cardiovascular prevention, with a median follow-up of 4.8 years. Diet, lipids, MLXIPL polymorphisms, and cardiovascular events were assessed. Data were analyzed at baseline and longitudinally. We used multivariable-adjusted Cox regression to estimate hazard ratios for cardiovascular outcomes. The MLXIPL -rs3812316 was associated with lower baseline triglycerides ( P =5.5×10 −5 ) and lower hypertriglyceridemia (odds ratio, 0.73; 95% confidence interval [CI], 0.63–0.85; P =1.4×10 −6 in G-carriers versus CC). This association was modulated by baseline adherence to MedDiet. When adherence to MedDiet was high, the protection was stronger (odds ratio, 0.63; 95% CI, 0.51–0.77; P =8.6×10 −6 ) than when adherence to MedDiet was low (odds ratio, 0.88; 95% CI, 0.70–1.09; P =0.219). Throughout the follow-up, both the MLXIPL -rs3812316 ( P =3.8×10 −6 ) and the MedDiet intervention ( P =0.030) were significantly associated with decreased triglycerides. Likewise in G-carriers MedDiet intervention was associated with greater total cardiovascular risk reduction and specifically for myocardial infarction. In the MedDiet, but not in the control group, we observed lower myocardial infarction incidence in G-carriers versus CC (hazard ratios, 0.34; 95% CI, 0.12–0.93; P =0.036 and 0.90; 95% CI, 0.35–2.33; P =0.830, respectively). Conclusions— Our novel results suggest that MedDiet enhances the triglyceride-lowering effect of the MLXIPL -rs3812316 variant and strengthens its protective effect on myocardial infarction incidence.
