RESUMEN
OBJECTIVE: This article aims to estimate the differences in environmental impact (greenhouse gas [GHG] emissions, land use, energy used, acidification and potential eutrophication) after one year of promoting a Mediterranean diet (MD). METHODS: Baseline and 1-year follow-up data from 5800 participants in the PREDIMED-Plus study were used. Each participant's food intake was estimated using validated semi-quantitative food frequency questionnaires, and the adherence to MD using the Dietary Score. The influence of diet on environmental impact was assessed through the EAT-Lancet Commission tables. The influence of diet on environmental impact was assessed through the EAT-Lancet Commission tables. The association between MD adherence and its environmental impact was calculated using adjusted multivariate linear regression models. RESULTS: After one year of intervention, the kcal/day consumed was significantly reduced (-125,1 kcal/day), adherence to a MD pattern was improved (+0,9) and the environmental impact due to the diet was significantly reduced (GHG: -361 g/CO2-eq; Acidification:-11,5 g SO2-eq; Eutrophication:-4,7 g PO4-eq; Energy use:-842,7 kJ; and Land use:-2,2 m2). Higher adherence to MD (high vs. low) was significantly associated with lower environmental impact both at baseline and one year follow-up. Meat products had the greatest environmental impact in all the factors analysed, both at baseline and at one-year follow-up, in spite of the reduction observed in their consumption. CONCLUSIONS: A program promoting a MD, after one year of intervention, significantly reduced the environmental impact in all the factors analysed. Meat products had the greatest environmental impact in all the dimensions analysed.

BACKGROUND AND AIMS: There is ongoing controversy about the effect of a low to moderate alcohol consumption on atrial fibrillation (AF). Our aim is to assess the association between adherence to a Mediterranean alcohol drinking pattern and AF incidence. METHODS AND RESULTS: A total 6527 out of the 7447 participants in the PREDIMED trial met our inclusion criteria. A validated frequency food questionnaire was used to measure alcohol consumption. Participants were classified as non-drinkers, Mediterranean alcohol drinking pattern (MADP) (10-30 g/d in men and 5-15 g/day in women, preferably red wine consumption with low spirits consumption), low-moderate drinking (<30 g/day men y and < 15 g/day women), and heavy drinking. We performed multivariable Cox regression models to estimate hazard ratios (HR) with 95% confidence intervals (95% CI) of incident AF according to alcohol drinking patterns. After a mean follow up of 4.4 years, 241 new incident AF cases were confirmed. Alcohol consumption was not associated to AF incidence among low-moderate drinkers (HR: 0.96; 95%CI: 0.67-1.37), adherents to MADP (HR: 1.15 95%CI: 0.75-1.75), or heavy drinkers (HR: 0.92; 95%CI: 0.53-1.58), compared with non-drinkers. CONCLUSIONS: In a high cardiovascular risk adult population, a Mediterranean alcohol consumption pattern (low to moderate red wine consumption) was not associated with an increased incidence of AF.

BACKGROUND: Recent studies show that most systemic mastocytosis (SM) patients, including indolent SM (ISM) with (ISMs+) and without skin lesions (ISMs-), carry the KIT D816V mutation in PB leukocytes. We investigated the potential association between the degree of involvement of BM hematopoiesis by the KIT D816V mutation and the distribution of different maturation-associated compartments of bone marrow (BM) and peripheral blood (PB) CD34+ hematopoietic precursors (HPC) in ISM and identified the specific PB cell compartments that carry this mutation. METHODS: The distribution of different maturation-associated subsets of BM and PB CD34+ HPC from 64 newly diagnosed (KIT-mutated) ISM patients and 14 healthy controls was analyzed by flow cytometry. In 18 patients, distinct FACS-purified PB cell compartments were also investigated for the KIT mutation. RESULTS: ISM patients showed higher percentages of both BM and PB MC-committed CD34+ HPC vs controls, particularly among ISM cases with MC-restricted KIT mutation (ISMMC ); this was associated with progressive blockade of maturation of CD34+ HPC to the neutrophil lineage from ISMMC to multilineage KIT-mutated cases (ISMML ). Regarding the frequency of KIT-mutated cases and cell populations in PB, variable patterns were observed, the percentage of KIT-mutated PB CD34+ HPC, eosinophils, neutrophils, monocytes and T cells increasing from ISMs-MC and ISMs+MC to ISMML patients. CONCLUSION: The presence of the KIT D816V mutation in PB of ISM patients is associated with (early) involvement of circulating CD34+ HPC and multiple myeloid cell subpopulations, KIT-mutated PB CD34+ HPC potentially contributing to early dissemination of the disease.

OBJECTIVE: To define whether the rs9939609 FTO (fat mass and obesity associated) single nucleotide polymorphism (SNP) is associated with anthropometric measurements and its modulation by educational level in a Mediterranean population. METHODS: We studied 3 independent adult samples: a random sample (n = 1580) from the general population (GP), obese hospital patients (OHP) (n = 203) and elderly subjects (n = 1027) with high cardiovascular risk (HCR). Weight and height were directly measured. Education and physical activity (PA) were measured using questionnaires. RESULTS: The rs9939609 presented heterogeneous associations with BMI. In the GP, the minor A-allele was significantly associated with greater BMI, following a co-dominant pattern (P = 0.009), whereas in the OHP this association was recessive (P = 0.004). Conversely, we did not find a significant association with BMI in the HCR group (P < 0.596). In the GP we found a significant interaction between the FTO SNP and education (P = 0.048). In the stratified analysis, no association of the FTO SNP with greater BMI in university subjects was detected (P = 0.786), whereas the association was observed in non-university subjects (P = 0.001). The FTO × education interaction (P = 0.020) was also observed in determining obesity risk in the GP. A-allele carriers had a greater risk of being obese only if they had no university education (OR: 1.56; 95%CI: 1.09-2.23 for TA and OR: 2.01; 95%CI: 1.27-3.26 for AA subjects). The interaction of the FTO with education remained significant even after adjustment for PA. CONCLUSIONS: The association of the FTO SNP with greater BMI and obesity risk in the GP was strongly modulated by education.

INTRODUCTION: The organ and tissue donation interview is a vital step in obtaining the donation. Therefore, it is important to obtain as much information as possible regarding the relatives of the potential donor prior to this interview and know if there is a health care professional among the relatives who may act as an interlocutor. OBJECTIVE: The objective of this study is to assess the influence that relatives who are health care professionals may have if present at the interview for the organ and tissue donation request. METHODS: This is a descriptive study of all the organ donations from 1996 to 2019. Variables of the interview record form were completed by the Regional Transplant Coordination Office. Quantitative variables are expressed as mean (standard deviation) or median (interquartile range), and qualitative variables are expressed in percentage. The χ2 test was used for inferential statistics. RESULTS: Health care professionals were present as interlocutors in 8.4% of the total interviews conducted (9279). Organ donation was accepted in 86% of these interviews, while the relative who was a health care professional gave a 93.8% (729) positive response to the donation. Having a health care professional as an interlocutor favors the acceptance of the donation (odds ratio 9.325, 95% confidence interval: 5.054-17.205; P < .001). CONCLUSION: Health care professionals have a very positive attitude toward donation. This attitude positively impacts other relatives' acceptance of the donation.

This study reveals that injecting a light fluid of density ρ_{b} in the recirculating bubble of a bluff body at Re≈6.4×10^{4} has a greater drag reduction potential than blowing fluid of a density greater than or equal to that of the free stream ρ. It is found that the maximum drag reduction scales as (ρ_{b}/ρ)^{-1/6}. This power law combines the ability of the recirculating bubble to diffuse the injected momentum and the effectiveness of the injection to increase the recirculating bubble length.
RESUMEN
BACKGROUND & AIMS: Little is known about the impact of specific dietary patterns on the development of obesity phenotypes. We aimed to determine the association of longitudinal changes in adherence to the traditional Mediterranean diet (MedDiet) with the transition between different obesity phenotypes. METHODS: Data of 5801 older men and women at high cardiovascular risk from PREDIMED trial were used. Adherence to MedDiet was measured with the validated 14p-Mediterranean Diet Adherence Screener (MEDAS). Using the simultaneous combination of metabolic health- and body size-related parameters participants were categorized into one of four phenotypes: metabolically healthy and abnormal obese (MHO and MAO), metabolically healthy and abnormal non-obese (MHNO and MANO). Cox regression models with yearly repeated measures during 5-year of follow-up were built with use of Markov chain assumption. RESULTS: Each 2-point increase in MEDAS was associated with the following transitions: in MAO participants, with a 16% (95% CI 3-31%) greater likelihood of becoming MHO; in MHO participants with a 14% (3-23%) lower risk of becoming MAO; in MHNO participants with a 18% (5-30%) lower risk of becoming MHO. In MANO women, but not in men, MEDAS was associated with 20% (5-38%) greater likely of becoming MHNO (p for interaction by gender 0.014). No other significant associations were observed. CONCLUSIONS: Better adherence to the traditional MedDiet is associated with transitions to healthier phenotypes, promoting metabolic health improvement in MAO, MANO (only in women), and MHO, as well as protecting against obesity incidence in MHNO subjects.

INTRODUCTION AND OBJECTIVES: Metabolic syndrome (MetS) is a combination of various cardiovascular risk factors with a major impact on morbidity and premature mortality. However, the impact of MetS on self-reported health-related quality of life (HRQoL) is unknown. This study evaluated the HRQoL in a Spanish adult population aged 55 years and older with MetS. METHOD: A cross-sectional analysis was performed with baseline data from the PREDIMED-Plus multicentre randomized trial. The participants were 6430 men and women aged 55-75 years with overweight/obesity (body mass index ≥27 and ≤40kg/m2) and MetS. The SF-36 questionnaire was used as a tool to measure HRQoL. Scores were calculated on each scale of the SF-36 by gender and age. RESULTS: Participants showed higher scores in the social function (mean 85.9, 95% CI; 85.4-86.4) and emotional role scales (mean 86.8, 95% CI; 86.0-87.5). By contrast, the worst scores were obtained in the aggregated physical dimensions. In addition, men obtained higher scores than women on all scales. Among men, the worst score was obtained in general health (mean 65.6, 95% CI; 65.0-66.2), and among women, in body pain (mean 54.3, 95%CI; 53.4-55.2). A significant decrease was found in the aggregated physical dimensions score among participants 70-75 years old, but an increased one in the aggregated mental dimensions, compared to younger participants. CONCLUSIONS: Our results reflect that the MetS may negatively affect HRQoL in the aggregated physical dimensions, body pain in women, and general health in men. However, this adverse association was absent for the psychological dimensions of HRQoL, which were less affected.

Sport induces cardiac adaptations that are manifested with specific electrocardiographic alterations. This study was carried out in view of the need to identify the relationship between these electrocardiographic alterations with cardiovascular and demographic variables and physical exercise performed. Methodology: a descriptive cross-sectional study in 370 individuals, 211 men and 159 women (36 ± 13 years) that were distributed in three groups: male athletes, female athletes, and non-athlete men and women. Results: 51.08% of the studied subjects presented electrographic alterations, more frequent in athletes. Demographic and cardiovascular variables and the time of physical exercise performed were significantly associated with certain electrocardiographic alterations; the risk of presenting any of the alterations in athletes could be estimated based on the variables set out. Conclusion: There are associations between specific electrocardiographic alterations and cardiovascular, demographic and type of exercise variables that could classify athletes according to cardiovascular risk profiles (AU)

BACKGROUND: The increasing number of samples from the biomedical genetic studies and the number of centers participating in the same involves increasing risk of mistakes in the different sample handling stages. We have evaluated the usefulness of the amelogenin test for quality control in sample identification. METHODS: Amelogenin test (frequently used in forensics) was undertaken on 1224 individuals participating in a biomedical study. Concordance between referred sex in the database and amelogenin test was estimated. Additional sex-error genetic detecting systems were developed. RESULTS: The overall concordance rate was 99.84% (1222/1224). Two samples showed a female amelogenin test outcome, being codified as males in the database. The first, after checking sex-specific biochemical and clinical profile data was found to be due to a codification error in the database. In the second, after checking the database, no apparent error was discovered because a correct male profile was found. False negatives in amelogenin male sex determination were discarded by additional tests, and feminine sex was confirmed. A sample labeling error was revealed after a new DNA extraction. CONCLUSION: The amelogenin test is a useful quality control tool for detecting sex-identification errors in large genomic studies, and can contribute to increase its validity.

HYPOTHESIS: The increase in the awareness of computers in the general population and the spread of Internet as a tool for communication and knowledge, allows patients to have greater understanding of their conditions. OBJECTIVE: To evaluate the use of Internet by the population from a health area and the knowledge extracted about their urological conditions. MATERIAL AND METHODS: This prospective study included all patients of age who attended a hospital urology clinic between 1st September and 31st December 2006, in a health area of 200,000 inhabitants. All patients were given a self-administered questionnaire to complete; medical staff did not intervene in filling it out in any case. The study variables were age (under 30, between 30 and 60 and over 60), sex, patient's pathology (only those with at least 5 cases were assessed), educational level (none, primary school qualification, intermediate studies and university studies), presence of a computer at home (yes/no), knowledge of the existence of internet (yes/no), searches performed on urological conditions and influence of these consultations in their relationship with their doctor. The relationship between the use of internet and the different variables was evaluated using the Kruskall-Wallis test. A probability of the null hypothesis less than 0.05 was considered significant. RESULTS: A total of 1,111 questionnaires were received, of which 1,062 were useful for processing. The mean age was 60.98 with a standard error of 15.08. 18.4% were women. The population distribution by level of studies was: 22.2% uneducated, 43.5% with primary education qualification, 27.5% with intermediate educational level and 6.8% university graduates. 58.4% of patients denied having a computer at home, 37.7% do not know what internet is, 76.7% do not have an e-mail address and just 6.7% visit medical pages, although only 1.5% admit having asked their doctor about information received on internet. According to classification by age, patients under 30 have significantly greater knowledge of computers and internet (p<0.001). However, there were no significant differences shown between the age and the fact of asking about information received through internet (p=0.1). The most visited web pages were, in order of the most to least visited: tuotromedico.com, varicocele.com, aecc.es, wikipedia.com, prostatitis.org, ondasalud.com and mapfrecajasalud.com. The most searched for conditions were: chronic prostatitis (25% of patients affected), testicular cancer (20% of patients), varicocele (18.7%), Peyronie's disease or congenital penile curvature (18.1%) and stenosis of the pyeloureteral junction (16.6%). CONCLUSIONS: --The exploitation of the internet as an information tool on the part of patients is very low, due to the characteristics inherent to our population, such as the low level of studies. --Urological web pages should dedicate an extensive part to the most common conditions in the younger population groups, such as varicocele or prostatitis. However, it is logical to expect that these epidemiological patterns will modify with time. --The use of internet and computers in general should be promoted among the different population groups in the health area under study.

BACKGROUND: It is necessary to have simple tools to screen erectile dysfunction (ED) in an easy, reliable and valid manner. The objective of this study was to develop and validate a short diagnostic questionnaire for erectile dysfunction [SQUED), easy to use in the primary care setting. SUBJECTS AND METHOD: The development of SQUED included: concepts identification, item generation and evaluation of contents and face validity through interviews with subjects to assess comprehension and idiomatic adequacy. The psychometric validation was conducted in an epidemiologic, observational, comparative and multicenter study. Participants should complete the questionnaire in primary care setting and send to the specialist to confirm the diagnosis by an in depth interview and the application of IIEF questionnaire. Internal consistency, test-retest reliability and sensitivity and specificity of SQUED was evaluated. RESULTS: Out of 405 subjects enrolled, 316 (208 ED and 108 non-ED) were evaluable. The SQUED questionnaire showed a high internal consistency (Cronbach's alpha = 0.92) and a good test-retest reliability (Kappa index = 0.77). Furthermore, the questionnaire showed a good diagnostic capacity with high values of sensitivity and specificity, 0.87 and 0.78, respectively, in relation to the diagnosis made by urologists. The cutting point was established at a score of 12. DISCUSSION: The SQUED questionnaire is a simple, easy to use and reliable instrument. It can become a useful tool, and the shortest validated, for primary care physicians to easily screen for ED patients. Its simplicity should facilitate an easy cultural adaptation and validation into other languages.

Systemic mastocytosis (SM) is a heterogeneous disease with altered interleukin (IL)-6 and IL13 plasma levels. However, no study has simultaneously investigated the plasma levels of IL1ß, IL6, IL13, CCL23 and clusterin in SM at diagnosis and correlated them with disease outcome. Here we investigated IL1ß, IL6, IL13, CCL23 and clusterin plasma levels in 75 SM patients--66 indolent SM (ISM) and 9 aggressive SM--and analyzed their prognostic impact among ISM cases grouped according to the extent of hematopoietic involvement of the bone marrow cells by the KIT D816V mutation. Although increased IL1ß, IL6 and CCL23 levels were detected in SM patients versus healthy controls, only IL6 and CCL23 levels gradually increased with disease severity. Moreover, increased IL6 plasma levels were associated with ISM progression to more aggressive disease, in particular among ISM patients with multilineal KIT mutation (ISM-ML), these patients also showing a higher frequency of organomegalies, versus other ISM-ML patients. Of note, all ISM patients who progressed had increased IL6 plasma levels already at diagnosis. Our results indicate that SM patients display an altered plasma cytokine profile already at diagnosis, increased IL6 plasma levels emerging as an early marker for disease progression among ISM cases, in particular among high-risk ISM patients who carry multilineage KIT mutation.

BACKGROUND AND OBJECTIVE: Erectile dysfunction (ED) is caused by a large range of organic, psychological, psychiatric, interpersonal and pharmacological factors. Numerous scientific publications mention the loss of self-esteem as a collateral effect of ED, with a very probable affectation of the subject's self-confidence. The objective of this study was to evaluate the self-esteem and self-confidence of subjects with ED and to compare them with a group of non-ED subjects. SUBJECTS AND METHOD: An epidemiological, cross-sectional, observational, comparative and multicentric study was conducted. General Practitioners selected 405 men older than 18 years in which they suspected ED. All the participants had to complete the self administered form of the Spanish version of the Rosenberg self-esteem scale and the Spanish culturally adapted version of the Johnson and McCoy self-confidence scale. After that, patients were referred to the urologist in order to confirm the ED diagnosis. RESULTS: The statistical analysis of the data showed that the subjects with ED obtained significantly lower scores in the self-confidence and self-esteem scales than the non-ED subjects (p < 0.01). DISCUSSION: The results of this study show the loss of self-confidence and self-esteem that suffer patients with ED.

Genetic variants at the cholesteryl ester transfer protein (CETP) locus have been associated with CETP activity and mass, as well as plasma high density lipoprotein cholesterol (HDL-C) and apolipoprotein A-I levels. We have examined allele frequencies and lipid associations for the common CETP TaqIB polymorphism in a sample of 514 healthy subjects (231 men, mean age 37.4 years, and 283 women, mean age 35.7 years) residing in Valencia (Spain). The frequency of the less common TaqIB2 allele (0.351; 95% CI: 0.322-0. 380) was significantly lower than those reported for Northern European populations. Consistent with previous studies, we found a significant association of the TaqIB polymorphism with HDL-C levels. Homozygotes for the B1 allele had lower HDL-C levels than subjects carrying the B2 allele (P trend<0.001 and 0.002, for men and women, respectively). No statistically significant genotype effects were observed for any of the other lipid measures. Multivariate models including TaqIB genotype, body mass index, smoking, alcohol, physical activity, marital status and education were fitted to predict HDL-C levels. The TaqIB polymorphism was consistently an independent predictor of HDL-C levels (P<0.001), and explained 5.8% of its variance. To evaluate gene-environmental interactions, first order interaction terms were tested into the multivariate model. No statistically significant interactions between the TaqIB genotypes and smoking, alcohol, physical activity or education were detected. In conclusion, we observed a significant association of the TaqIB polymorphism with HDL-C levels, which remained consistent across different levels of behavioral factors. Moreover, we found that the TaqIB2 allele frequency was lower in our sample than in other European populations, which could be a contributing factor to the unexpectedly high prevalence of coronary heart disease observed in the region of Valencia.

The effects of atenolol (100 mg/day) and nifedipine (20 mg 3 times daily) and their combination on ambulant myocardial ischemia were investigated using a randomized, double-blind, placebo-controlled, crossover trial. Eighteen men with symptomatic coronary artery disease, exercise-induced ischemia and minimal symptoms, underwent 4 blinded treatment periods of 2 weeks' duration (2 placebo, 1 atenolol, 1 nifedipine). Those that did not have ischemia eliminated by monotherapy received combination therapy with both drugs. Forty-eight-hour ambulatory electrocardiographic monitoring was used to quantitate ischemic parameters at the end of each period. Both nifedipine and atenolol as monotherapy reduced the number of ischemic episodes and the average duration of each episode compared with placebo (p less than 0.05). Compared with placebo, nifedipine reduced the total duration of ischemia (p less than 0.05) but the effect of atenolol on ischemia duration was of borderline significance (p = 0.066). There were no differences in reduction of ischemic parameters when atenolol was compared with nifedipine (difference not significant). In the 9 patients who continued to have ischemia with monotherapy, combination therapy eliminated it in 2 and reduced the duration by greater than 50% in the remaining patients compared with placebo. In conclusion, monotherapy with nifedipine or atenolol is similarly effective in eliminating or reducing ambulant ischemia. Combination therapy can provide additional benefit in those with continued ischemia.

The value of right-sided cardiac catheterization was assessed prospectively in 200 patients undergoing left-sided catheterization for evaluation of known or suspected coronary artery disease. Before catheterization, data from right-sided catheterization was not felt to be necessary for clinical management. There were 6 +/- 2 extra minutes of procedure time and 86 +/- 63 extra seconds of fluoroscopy time used. Abnormalities were detected in 69 (35%) patients. These findings were unexpected in 37 of these patients and in 3 patients, further evaluation was prompted. However, management was altered in only 3 (1.5%) patients as a result of data obtained by right-sided catheterization. In conclusion this additional procedure rarely adds clinically useful information about patients undergoing left-sided catheterization and angiography for coronary artery disease without a clinical indication for right-sided catheterization.
