Gazpacho consumption is associated with lower blood pressure and reduced hypertension in a high cardiovascular risk cohort. Cross-sectional study of the PREDIMED trial

Hypertension is a major public health problem and a leading cause of death and disability in both developed and developing countries, affecting onequarter of the world"s adult population. Our aim was to evaluate whether the consumption of gazpacho, a Mediterranean vegetable-based cold soup rich in phytochemicals, is associated with lower blood pressure (BP) and/or reduced prevalence of hypertension in individuals at high cardiovascular risk. Methods and results: We selected 3995 individuals (58% women, mean age 67 y) at high cardiovascular risk (81% hypertensive) recruited into the PREDIMED study. BP, weight, and dietary and physical activity data were collected. In multivariate linear regression analyses, after adjustment, moderate and high gazpacho consumption categories were associated with reduced mean systolic BP of 1.9 mm Hg [95% confidence interval (CI): 3.4; 0.6] and 2.6 mm Hg (CI: 4.2; 1.0), respectively, and reduced diastolic BP of 1.5 mm Hg (CI: 2.3; 0.6) and 1.9 mm Hg (CI: 2.8; 1.1). By multiple-adjusted logistic regression analysis, gazpacho consumption was associated with a lower prevalence of hypertension, with OR Z 0.85 (CI: 0.73; 0.99) for each 250 g/week increase and OR Z 0.73 (CI: 0.55; 0.98) for high gazpacho consumption groups compared to the no-consumption group. Conclusions: Gazpacho consumption was inversely associated with systolic and diastolic BP and prevalence of hypertension in a cross-sectional Mediterranean population at high cardiovascular risk. The association between gazpacho intake and reduction of BP is probably due to synergy among several bioactive compounds present in the vegetable ingredients used to make the recipe.

Enhanced vascular contractility in alpha1-adrenergic receptor-deficient mice.

AIM: Alpha1-adrenergic receptors (alpha1-ARs) are classified into three subtypes: alpha1A-AR, alpha1B-AR, and alpha1D-AR. Triple disruption of alpha1A-AR, alpha1B-AR, and alpha1D-AR genes results in hypotension and produces no contractile response of the thoracic aorta to noradrenalin. Presently, we characterized vascular contractility against other vasoconstrictors, such as potassium, prostaglandin F2alpha (PGF(2alpha)) and 5-hydroxytryptamine (5-HT), in alpha1A-AR, alpha1B-AR, and alpha1D-AR triple knockout (alpha1-AR triple KO) mice. MAIN METHODS: The contractile responses to the stimulation with vasoconstrictors were studied using isolated thoracic aorta. KEY FINDINGS: As a result, the phasic and tonic contraction induced by a high concentration of potassium (20 mM) was enhanced in the isolated thoracic aorta of alpha1-AR triple KO mice compared with that of wild-type (WT) mice. In addition, vascular responses to PGF(2alpha) and 5-HT were also enhanced in the isolated thoracic aorta of alpha1-AR triple KO mice compared with WT mice. Similar to in vitro findings with isolated thoracic aorta, in vivo pressor responses to PGF(2alpha) were enhanced in alpha1-AR triple KO mice. Real-time reverse transcription-polymerase chain reaction analysis and western blot analysis indicate that gene expression of the 5-hydroxytryptamine 2A (5-HT(2A)) receptor was up-regulated in the thoracic aorta of alpha1-AR triple KO mice while the prostaglandin F2alpha receptor (FP) was unchanged. SIGNIFICANCE: These results suggest that loss of alpha1-ARs can lead to enhancement of vascular responsiveness to the vasoconstrictors and may imply that alpha1-ARs and the subsequent signaling regulate the vascular responsiveness to other stimulations such as depolarization, 5-HT and PGF(2alpha).

Pharmacoeconomics of Cyclamen europaeum in the management of Acute Rhinosinusitis

Objective. To carry out a pharmacoeconomic analysis of Cyclamen europaeum (CE) in the management of acute rhinosinusitis (ARS) in Spain using data from the PROSINUS study. Study Design. This was a prospective observational study to compare the effectiveness and cost-effectiveness between therapies including CE vs. other therapies in the management of ARS. Methods. The study was carried out as a secondary analysis of the PROSINUS, combining healthcare resource use, productivity loses, and health outcomes from the observational study with costs representative of the Spanish Health System. Results. CE given as monotherapy appears to be more effective (cure rate) than other monotherapies (15.3% higher, p<0.05) and combination (10.3% higher, p<0.05) therapies. The addition of CE to other single-drug or combination therapies showed a statistically significant improvement in terms of cure rates when adding CE to 2-drug combinations (93.9% vs. 76.5%; p<0.05), and no significant effect when added to combinations of three or more drugs (81.1% vs. 79.8; NS). CE based therapies generally showed lower indirect costs, although only the comparison of CE alone vs. other monotherapies, with a net cost savings of 101 per patient, reached statistical significance (331 vs. 432 , p<0.05). In addition, CE-based therapies show lower cost per cured patient in all comparisons except when CE was used in combination with three or more other drugs. Conclusions. The use of Cyclamen europaeum may be associated to better clinical outcomes at no additional cost for the healthcare system, respect to treatments commonly used for ARS in clinical practice.

The alpha1-adrenergic receptors in cardiac hypertrophy: Signaling mechanisms and functional implications.

Cardiac hypertrophy is a complex remodeling process of the heart induced by physiological or pathological stimuli resulting in increased cardiomyocyte size and myocardial mass. Whereas cardiac hypertrophy can be an adaptive mechanism to stressful conditions of the heart, prolonged hypertrophy can lead to heart failure which represents the primary cause of human morbidity and mortality. Among G protein-coupled receptors, the α1-adrenergic receptors (α1-ARs) play an important role in the development of cardiac hypertrophy as demonstrated by numerous studies in the past decades, both in primary cardiomyocyte cultures and genetically modified mice. The results of these studies have provided evidence of a large variety of α1-AR-induced signaling events contributing to the defining molecular and cellular features of cardiac hypertrophy. Recently, novel signaling mechanisms have been identified and new hypotheses have emerged concerning the functional role of the α1-adrenergic receptors in the heart. This review will summarize the main signaling pathways activated by the α1-AR in the heart and their functional implications in cardiac hypertrophy.

Assessing Recent Selection and Functionality at Long Noncoding RNA Loci in the Mouse Genome.

Long noncoding RNAs (lncRNAs) are one of the most intensively studied groups of noncoding elements. Debate continues over what proportion of lncRNAs are functional or merely represent transcriptional noise. Although characterization of individual lncRNAs has identified approximately 200 functional loci across the Eukarya, general surveys have found only modest or no evidence of long-term evolutionary conservation. Although this lack of conservation suggests that most lncRNAs are nonfunctional, the possibility remains that some represent recent evolutionary innovations. We examine recent selection pressures acting on lncRNAs in mouse populations. We compare patterns of within-species nucleotide variation at approximately 10,000 lncRNA loci in a cohort of the wild house mouse, Mus musculus castaneus, with between-species nucleotide divergence from the rat (Rattus norvegicus). Loci under selective constraint are expected to show reduced nucleotide diversity and divergence. We find limited evidence of sequence conservation compared with putatively neutrally evolving ancestral repeats (ARs). Comparisons of sequence diversity and divergence between ARs, protein-coding (PC) exons and lncRNAs, and the associated flanking regions, show weak, but significantly lower levels of sequence diversity and divergence at lncRNAs compared with ARs. lncRNAs conserved deep in the vertebrate phylogeny show lower within-species sequence diversity than lncRNAs in general. A set of 74 functionally characterized lncRNAs show levels of diversity and divergence comparable to PC exons, suggesting that these lncRNAs are under substantial selective constraints. Our results suggest that, in mouse populations, most lncRNA loci evolve at rates similar to ARs, whereas older lncRNAs tend to show signals of selection similar to PC genes.

A 14-item Mediterranean diet assessment tool and obesity indexes among high-risk subjects: the PREDIMED trial

Objective: Independently of total caloric intake, a better quality of the diet (for example, conformity to the Mediterranean diet) is associated with lower obesity risk. It is unclear whether a brief dietary assessment tool, instead of full-length comprehensive methods, can also capture this association. In addition to reduced costs, a brief tool has the interesting advantage of allowing immediate feedback to participants in interventional studies. Another relevant question is which individual items of such a brief tool are responsible for this association. We examined these associations using a 14-item tool of adherence to the Mediterranean diet as exposure and body mass index, waist circumference and waist-to-height ratio (WHtR) as outcomes. Design: Cross-sectional assessment of all participants in the"PREvención con DIeta MEDiterránea" (PREDIMED) trial. Subjects: 7,447 participants (55-80 years, 57% women) free of cardiovascular disease, but with either type 2 diabetes or $3 cardiovascular risk factors. Trained dietitians used both a validated 14-item questionnaire and a full-length validated 137-item food frequency questionnaire to assess dietary habits. Trained nurses measured weight, height and waist circumference. Results: Strong inverse linear associations between the 14-item tool and all adiposity indexes were found. For a two-point increment in the 14-item score, the multivariable-adjusted differences in WHtR were 20.0066 (95% confidence interval,- 0.0088 to 20.0049) for women and-0.0059 (-0.0079 to-0.0038) for men. The multivariable-adjusted odds ratio for a WHtR.0.6 in participants scoring $10 points versus #7 points was 0.68 (0.57 to 0.80) for women and 0.66 (0.54 to 0.80) for men. High consumption of nuts and low consumption of sweetened/carbonated beverages presented the strongest inverse associations with abdominal obesity. Conclusions: A brief 14-item tool was able to capture a strong monotonic inverse association between adherence to a good quality dietary pattern (Mediterranean diet) and obesity indexes in a population of adults at high cardiovascular risk.

Low-fat dairy products and blood pressure: follow-up of 2290 older persons at high cardiovascular risk participating in the PREDIMED study

High blood pressure (BP) has been ranked as the most important risk factor worldwide regarding attributable deaths. Dietary habits are major determinants of BP. Among them, frequent intake of low-fat dairy products may protect against hypertension. Our aim was to assess the relationship between low-fat dairy product intake and BP levels and their changes after 12 month follow-up in a cohort of asymptomatic older persons at high cardiovascular risk recruited into a large-scale trial assessing the effects of Mediterranean diets on cardiovascular outcomes. Data from 2290 participants, including 1845 with hypertension, were available for analyses. Dairy products were not a specific part of the intervention; thus, data were analysed as an observational cohort. Dietary information was collected with validated semi-quantitative FFQ and trained personnel measured BP. To assess BP changes, we undertook cross-sectional analyses at baseline and at the end of follow-up and longitudinal analyses. A statistically significant inverse association between low-fat dairy product intake and systolic BP was observed for the 12-month longitudinal analysis. In the longitudinal analysis, the adjusted systolic and diastolic BP were significantly lower in the highest quintile of low-fat dairy product intake ( 2 4·2 (95% CI 2 6·9, 2 1·4) and 2 1·8 (95% CI 2 3·2, 2 0·4) mmHg respectively), whereas the point estimates for the difference in diastolic BP indicated a modest non-significant inverse association. Intake of low-fat dairy products was inversely associated with BP in an older population at high cardiovascular risk, suggesting a possible protective effect against hypertension.

Polymorphisms cyclooxygenase-2 -765G>C and interleukin-6 -174G>C are associated with serum inflammation markers in a high cardiovascular risk population and do not modify the response to a Mediterranean diet supplemented with virgin olive oil or nuts

Inflammation is involved in cardiovascular diseases. Some studies have found that the Mediterranean diet (MD) can reduce serum concentrations of inflammation markers. However, none of these studies have analyzed the influence of genetic variability in such a response. Our objective was to study the effect of the -765G.C polymorphism in the cyclooxygenase-2 (COX-2) gene and the -174G.C polymorphism in the interleukin-6 (IL-6) gene on serum concentrations of IL-6, C-reactive protein, intercellular adhesion molecule 1 (ICAM-1) and vascular cell adhesion molecule-1 as well as their influence on the response toa nutritional interventionwithMD.An intervention study ina high cardiovascular riskMediterranean population (314 men and 407 women) was undertaken. Participants were randomly assigned to consume a low-fat control diet or a MD supplementedwith virgin olive oil ornuts.Measureswereobtained at baseline and after a 3-mointervention period.At baseline, the COX-2 -765G.C polymorphismwas associated with lower serum IL-6 (5.85 6 4.82 in GG vs. 4.74 6 4.14 ng/L in C-allele carriers; P ¼ 0.002) and ICAM-1 (265.8 6 114.8 in GG vs. 243.0 6 107.1 mg/L in C-carriers; P ¼ 0.018) concentrations. These differences remained significant aftermultivariate adjustment. The IL-6 -174G.C polymorphism was associatedwith higher (CC vs. G-carriers) serumICAM-1concentrations in bothmenandwomenandwithhigherserumIL-6 concentrations inmen.Following the dietary intervention, no significant gene x diet interactions were found. In conclusion, although COX-2 -765G.C and IL-6 -174G.C polymorphismswere associatedwith inflammation, consuming aMD(either supplemented with virgin olive oil or nuts) reduced the concentration of inflammation markers regardless of these polymorphisms.

Fast and sensitive supercritical fluid chromatography - tandem mass spectrometry multi-class screening method for the determination of doping agents in urine.

This study shows the possibility offered by modern ultra-high performance supercritical fluid chromatography combined with tandem mass spectrometry in doping control analysis. A high throughput screening method was developed for 100 substances belonging to the challenging classes of anabolic agents, hormones and metabolic modulators, synthetic cannabinoids and glucocorticoids, which should be detected at low concentrations in urine. To selectively extract these doping agents from urine, a supported liquid extraction procedure was implemented in a 48-well plate format. At the tested concentration levels ranging from 0.5 to 5 ng/mL, the recoveries were better than 70% for 48-68% of the compounds and higher than 50% for 83-87% of the tested substances. Due to the numerous interferences related to isomers of steroids and ions produced by the loss of water in the electrospray source, the choice of SFC separation conditions was very challenging. After careful optimization, a Diol stationary phase was employed. The total analysis time for the screening assay was only 8 min, and interferences as well as susceptibility to matrix effect (ME) were minimized. With the developed method, about 70% of the compounds had relative ME within the range ±20%, at a concentration of 1 and 5 ng/mL. Finally, limits of detection achieved with the above-described strategy including 5-fold preconcentration were below 0.1 ng/mL for the majority of the tested compounds. Therefore, LODs were systematically better than the minimum required performance levels established by the World anti-doping agency, except for very few metabolites.
