    (National Institute of Environmental Health Sciences (NIEHS), 2025-04) Pastor-Barriuso, Roberto; Gutiérrez-González, Enrique; Varea-Jiménez, Elena; Gómez-Ariza, José Luis; Castaño-Vinyals, Gemma; Aragonés, Nuria; Molina, Antonio José; Dierssen-Sotos, Trinidad; Fernández-Tardón, Guillermo; Amiano, Pilar; Ederra-Sanz, María; Moreno, Victor; Jiménez-Moleón, José Juan; Molina-Barceló, Ana; Marcos-Gragera, Rafael; Casabonne, Delphine; Alguacil, Juan; Gómez-Gómez, Jesús Humberto; García-Barrera, Tamara; Kogevinas, Manolis; Pollan-Santamaria, Marina; Perez-Gomez, Beatriz; Instituto de Salud Carlos III; Asociación Española Contra el Cáncer; Centro de Investigación Biomédica en Red - CIBERESP (Epidemiología y Salud Pública); Scientific Foundation
    Background: Toenails are promising biomarkers of long-term metal exposure in epidemiological studies, but their accuracy may be compromised by systematic and random errors associated with heterogeneous toenail sample masses, as well as by substantial variability across laboratory batches. Objectives: We propose a novel modeling approach to calibrate toenail metal concentrations for the heterogeneity in sample masses and the variability between batches. Methods: We developed a heteroscedastic spline mixed model relating sample mass and laboratory batch with measured concentrations, allowing for an average bias in measurements over all batches as a smooth function of sample mass, random variation in mass-related biases across batches, and mass-related heterogeneity in within-batch error variance. The model allowed partitioning the total variance of measured concentrations into the extraneous variances (due to different sample masses and laboratory batches) and the intrinsic variance (resulting from distinct metal exposures). We derived calibrated metal concentrations from the model by removing both sources of extraneous variation and estimating the predicted concentrations had all toenail samples been analyzed in a single batch and of the same mass. We provide the R script COMET (COrrected METals) to fit the proposed model, extract variance components, and calibrate metal concentrations. Results: In a multicase-control study in Spain (MCC-Spain) with toenail determinations for 16 metals in 4,473 incident cases of five common cancers and 3,450 population controls, sample mass and batch accounted for 26%-60% of the total variance of measured concentrations for most metals. In comparison with calibrated concentrations, odds ratios for measured concentrations were biased by > 10% toward or away from the null in one-quarter of the estimated metal-cancer associations. Discussion: The proposed model allows correcting toenail metal concentrations for sample mass heterogeneity and between-batch variability and could be applied to other biological specimens of heterogeneous size, distinct laboratory techniques, and different study designs.

    Monitoring of Pseudomonas aeruginosa mutational resistome dynamics using an enrichment panel for direct sequencing of clinical samples
    (Elsevier, 2024-10) Cortes-Lara, Sara; Medina-Reatiga, Paola; Barrio-Tofiño, Ester Del; Gomis-Font, María A; Cabot, Gabriel; Gómez-Romano, Fernando; Ayestarán, Ignacio; Colomar, Asunción; Palou-Rotger, Alexandre; Oteo-Iglesias, Jesus; Campo, Rosa Del; Cantón, Rafael; Horcajada, Juan P; López-Causapé, Carla; Oliver, Antonio; Instituto de Salud Carlos III; Ministerio de Ciencia e Innovación (España); Unión Europea.

    Background: Pseudomonas aeruginosa is a major cause of hospital-acquired and chronic infections, characterised by an extraordinary capacity to develop antimicrobial resistance through the selection of chromosomal mutations, leading to treatment failure. Here, we designed and tested a hybridisation-based capture system for the enrichment of genes of interest before sequencing to monitor resistant populations genomics directly from clinical samples. Methods: A panel for enrichment before sequencing of close to 200 genes related to P. aeruginosa antimicrobial resistance, multilocus sequence typing, mutability or virulence was designed, synthesised (KAPA HyperCap, Roche) and initially validated in vitro using a multidrug-resistant ST175 isolate and representative isolates from major P. aeruginosa clades. In vivo testing included ventilator associated pneumonia by MDR P. aeruginosa in ICU (3-10 sequential samples from 3 patients) and chronic respiratory infection by hypermutable P. aeruginosa in cystic fibrosis (8 sequential samples from a single patient covering a 4-year period). Results from direct sequencing with the enrichment panel were compared with those of whole genome sequencing (WGS) and phenotypic profiling of 10 isolated colonies per sample. Findings: In vitro assays confirmed the selectivity of the enrichment panel and the correct identification of the vast mutational resistome of ST175, including specific mutations even when introduced in a 1:100 proportion. In vivo performance was at least equivalent to sequencing 10 colonies per sample, including the accurate identification of the sequence types and the basal and acquired mutational resistome. To note, specific resistance mutations, such as those in ampC leading to resistance to novel β-lactams, could be traced even at frequencies of 1%. Moreover, the coselection of mutator populations and antibiotic resistance mutations, predicted in theoretical and in vitro studies, was evidenced in vivo. Interpretation: This proof-of-concept study demonstrates that resistance genomics of P. aeruginosa can be analysed directly from clinical samples, determining not only a considerable reduction in turnaround time and cost from a diagnostics perspective, but also an unprecedented potency for accurate monitoring of in vivo population dynamics in bacterial infections.

    The aim of our study is to evaluate the relationship between sociodemographic and clinical characteristics of individuals with Colorectal Cancer (CRC), tumour-intrinsic characteristics and treatment received with health-related quality of life (HRQoL). Methods: Cross-sectional analysis of data from 805 survivors from the MCC study was conducted. HRQoL was assessed through a general and specific questionnaire, SF-12 and FCSI (Colorectal Symptom Index). Statistical analyses were performed with linear regression with adjustment for sociodemographic variables, stage at diagnosis and histological grade. Results: Participants had survived a median of 7.9 years from diagnosis (IQR 7.1-8.5 years). Age at diagnosis, sex and area showed a clear association with HRQoL in both physical and mental dimensions of the SF-12 questionnaire. A direct association between CRC recurrence was also found in the PCS-12 and MCS-12 dimensions and radical surgery in the PCS-12. Regarding the scores in FCSI questionnaire, statistically significant differences were observed by sex, age and area, with older women being the most impaired (p < 0.001). Conclusions: Age, sex and area was associated with lower scores of HRQoL among CRC survivors. Knowing the determinants related to HRQoL would allow us to lay the groundwork to develop strategies that help reduce morbidity and mortality, relapses and increase HRQoL.

    Background: 10% of postmenopausal breast cancer cases are attributed to a high body mass index (BMI). BMI underestimates body fat, particularly in older women, and therefore the cancer burden attributable to obesity may be even higher. However, this is not clear. CUN-BAE (Clínica Universidad de Navarra-Body Adiposity Estimator) is an accurate validated estimator of body fat, taking into account sex and age. The objective of this study was to compare the burden of postmenopausal breast cancer attributable to excess body fat calculated using BMI and CUN-BAE. Methods: This case-control study included 1033 cases of breast cancer and 1143 postmenopausal population controls from the multicase-control MCC-Spain study. Logistic regression models were used to calculate odds ratios (ORs). The population attributable fraction (PAF) of excess weight related to breast cancer was estimated with both anthropometric measures. Stratified analyses were carried out for hormone receptor type. Results: Excess body weight attributable to the risk of breast cancer was 23.0% when assessed using a BMI value ≥30 kg/m2 and 38.0% when assessed using a CUN-BAE value of ≥40% body fat. Hormone receptor stratification showed that these differences in PAFs were only observed in hormone receptor positive cases, with an estimated burden of 19.9% for BMI and 41.9% for CUN-BAE. Conclusion: These findings suggest that the significance of excess body fat in postmenopausal hormone receptor positive breast cancer could be underestimated when assessed using only BMI. Accurate estimation of the cancer burden attributable to obesity is crucial for planning effective prevention initiatives.

    Global, regional, and national burden of stroke and its risk factors, 1990-2021: a systematic analysis for the Global Burden of Disease Study 2021
    (Elsevier, 2024-10) GBD 2021 Stroke Risk Factor Collaborators; Padron-Monedero, Alicia; Bill & Melinda Gates Foundation
    Background: Up-to-date estimates of stroke burden and attributable risks and their trends at global, regional, and national levels are essential for evidence-based health care, prevention, and resource allocation planning. We aimed to provide such estimates for the period 1990-2021. Methods: We estimated incidence, prevalence, death, and disability-adjusted life-year (DALY) counts and age-standardised rates per 100 000 people per year for overall stroke, ischaemic stroke, intracerebral haemorrhage, and subarachnoid haemorrhage, for 204 countries and territories from 1990 to 2021. We also calculated burden of stroke attributable to 23 risk factors and six risk clusters (air pollution, tobacco smoking, behavioural, dietary, environmental, and metabolic risks) at the global and regional levels (21 GBD regions and Socio-demographic Index [SDI] quintiles), using the standard GBD methodology. 95% uncertainty intervals (UIs) for each individual future estimate were derived from the 2·5th and 97·5th percentiles of distributions generated from propagating 500 draws through the multistage computational pipeline. Findings: In 2021, stroke was the third most common GBD level 3 cause of death (7·3 million [95% UI 6·6-7·8] deaths; 10·7% [9·8-11·3] of all deaths) after ischaemic heart disease and COVID-19, and the fourth most common cause of DALYs (160·5 million [147·8-171·6] DALYs; 5·6% [5·0-6·1] of all DALYs). In 2021, there were 93·8 million (89·0-99·3) prevalent and 11·9 million (10·7-13·2) incident strokes. We found disparities in stroke burden and risk factors by GBD region, country or territory, and SDI, as well as a stagnation in the reduction of incidence from 2015 onwards, and even some increases in the stroke incidence, death, prevalence, and DALY rates in southeast Asia, east Asia, and Oceania, countries with lower SDI, and people younger than 70 years. Globally, ischaemic stroke constituted 65·3% (62·4-67·7), intracerebral haemorrhage constituted 28·8% (28·3-28·8), and subarachnoid haemorrhage constituted 5·8% (5·7-6·0) of incident strokes. There were substantial increases in DALYs attributable to high BMI (88·2% [53·4-117·7]), high ambient temperature (72·4% [51·1 to 179·5]), high fasting plasma glucose (32·1% [26·7-38·1]), diet high in sugar-sweetened beverages (23·4% [12·7-35·7]), low physical activity (11·3% [1·8-34·9]), high systolic blood pressure (6·7% [2·5-11·6]), lead exposure (6·5% [4·5-11·2]), and diet low in omega-6 polyunsaturated fatty acids (5·3% [0·5-10·5]). Interpretation: Stroke burden has increased from 1990 to 2021, and the contribution of several risk factors has also increased. Effective, accessible, and affordable measures to improve stroke surveillance, prevention (with the emphasis on blood pressure, lifestyle, and environmental factors), acute care, and rehabilitation need to be urgently implemented across all countries to reduce stroke burden.

    Scope: Diets rich in polyphenols has been associated with better cognitive performance. The aim of this study is to assess the relationship between microbial phenolic metabolites (MPM) in urine and cognition in the context of an older population at high cardiovascular risk. Methods and results: A cross-sectional analysis is conducted in 400 individuals of the PREDIMED-Plus study. Liquid chromatography coupled to mass spectrometry is used to identify urinary MPM. Mediterranean diet (MedDiet) adherence is estimated with a 17-item questionnaire and cognitive function is evaluated with a battery of neuropsychological tests. Multivariable-adjusted linear regression models are fitted to assess the relationship of urinary MPM with the MedDiet and cognitive tests. Protocatechuic acid and enterolactone glucuronide are associated with higher adherence to the MedDiet. Regarding cognitive function, protocatechuic acid, vanillic acid glucuronide, 3-hydroxybenzoic acid, enterodiol glucuronide, and enterolactone glucuronide are directly associated with a global composite score of all the cognitive tests. Furthermore, protocatechuic acid and enterolactone glucuronide are associated with higher scores in the Mini-Mental State Examination, whereas enterodiol glucuronide is associated with improved Clock Drawing Test scores. Conclusions: These results suggest that the MedDiet is linked to MPM associated with better cognitive performance in an older population.

    Association between type 2 diabetes and depressive symptoms after a 1-year follow-up in an older adult Mediterranean population
    (Springer, 2024-01-13) Baenas, I; Camacho-Barcia, L; Granero, R; Razquin, C; Corella, D; Gómez-Martínez, Carlos; Castañer-Niño, O; Martínez, JA; Alonso-Gómez, ÁM; Wärnberg, Julia; Vioque, Jesus; Romaguera, Dora; López-Miranda, J; Estruch, R; Tinahones, Francisco J; Lapetra, J; Serra-Majem, Lluis; Cano-Ibáñez, N; Tur, Josep A; Martín-Sánchez, V; Pintó, X; Gaforio, J J; Matía-Martín, P; Vidal, Josep; Vazquez, Clotilde; Daimiel, L; Ros, Emilio; Jiménez-Murcia, S; Dalsgaard, S; Garcia-Arellano, A; Babio, N; Sorli, Jose V; Lassale, C; García-de-la-Hera, M; Gómez-García, E; Zulet, MA; Konieczna, Jadwiga; Martín-Peláez, S; Tojal-Sierra, Lucas; Basterra-Gortari, FJ; de Las Heras-Delgado, S; Portoles, O; Muñoz-Pérez, MÁ; Arenas-Larriva, AP; Compañ-Gabucio, L; Eguaras, S; Shyam, Sangeetha; Fitó, M; Baños, RM; Salas-Salvado, Jordi; Fernández-Aranda, F
    Objectives: To examine the cross-sectional association between baseline depressive symptoms and the presence of type 2 diabetes (T2D), and its association with glycated hemoglobin (HbA1c) and other metabolic variables, and the prospective association of depressive symptoms and HbA1c after 1 year of follow-up. Methods: n = 6224 Mediterranean older adults with overweight/obesity and metabolic syndrome (48% females, mean age 64.9 ± 4.9 years) were evaluated in the framework of the PREDIMED-Plus study cohort. Depressive symptoms were assessed using the Beck Depression Inventory-II and HbA1c was used to measure metabolic control. Results: The presence of T2D increased the likelihood of higher levels of depressive symptoms (χ2 = 15.84, p = 0.001). Polynomial contrast revealed a positive linear relationship (χ2 = 13.49, p = 0.001), the higher the depressive symptoms levels, the higher the prevalence of T2D. Longitudinal analyses showed that the higher baseline depressive symptoms levels, the higher the likelihood of being within the HbA1c ≥ 7% at 1-year level (Wald-χ2 = 24.06, df = 3, p < .001, for the full adjusted model). Additionally, depressive levels at baseline and duration of T2D predicted higher HbA1c and body mass index, and lower physical activity and adherence to Mediterranean Diet at 1 year of follow-up. Conclusions: This study supports an association between T2D and the severity of depressive symptoms, suggesting a worse metabolic control from mild severity levels in the short-medium term, influenced by lifestyle habits related to diabetes care. Screening for depressive symptoms and a multidisciplinary integrative therapeutic approach should be ensured in patients with T2D.

    Role of PATJ in stroke prognosis by modulating endothelial to mesenchymal transition through the Hippo/Notch/PI3K axis
    (Nature Publishing Group, 2024-02-17) Medina-Dols, Aina; Cañellas, Guillem; Capó, Toni; Solé, Montse; Mola-Caminal, Marina; Cullell, Natalia; Jaume, Marina; Nadal-Salas, Laura; Llinàs, Jaume; Gómez, Lluis; Tur Campos, Silvia; Jiménez Martínez, Carmen; Diaz Navarro, Rosa; Carrera, Caty; Muiño, Elena; Gallego-Fabrega, Cristina; Soriano-Tarraga, Carolina; Ruiz-Guerra, Laura; Pol-Fuster, Josep; Asensio, Víctor José; Muncunill Farreny, Josep; Fleischer, Aarne; Iglesias, Amanda; Giralt-Steinhauer, Eva; Lazcano, Uxue; Fernández-Pérez, Isabel; Jiménez-Balado, Joan; Gabriel-Salazar, Marina; Garcia-Gabilondo, Miguel; Lei, Ting; Torres-Aguila, Nuria-Paz; Cárcel-Márquez, Jara; Lladó, Jerònia; Olmos, Gabriel; Rosell, Anna; Montaner, Joan; Planas, Anna M; Rabionet, Raquel; Hernández-Guillamon, Mar; Jiménez-Conde, Jordi; Fernández-Cadenas, Israel; Vives-Bauza, Cristofol
    Through GWAS studies we identified PATJ associated with functional outcome after ischemic stroke (IS). The aim of this study was to determine PATJ role in brain endothelial cells (ECs) in the context of stroke outcome. PATJ expression analyses in patient's blood revealed that: (i) the risk allele of rs76221407 induces higher expression of PATJ, (ii) PATJ is downregulated 24 h after IS, and (iii) its expression is significantly lower in those patients with functional independence, measured at 3 months with the modified Rankin scale ((mRS) ≤2), compared to those patients with marked disability (mRS = 4-5). In mice brains, PATJ was also downregulated in the injured hemisphere at 48 h after ischemia. Oxygen-glucose deprivation and hypoxia-dependent of Hypoxia Inducible Factor-1α also caused PATJ depletion in ECs. To study the effects of PATJ downregulation, we generated PATJ-knockdown human microvascular ECs. Their transcriptomic profile evidenced a complex cell reprogramming involving Notch, TGF-ß, PI3K/Akt, and Hippo signaling that translates in morphological and functional changes compatible with endothelial to mesenchymal transition (EndMT). PATJ depletion caused loss of cell-cell adhesion, upregulation of metalloproteases, actin cytoskeleton remodeling, cytoplasmic accumulation of the signal transducer C-terminal transmembrane Mucin 1 (MUC1-C) and downregulation of Notch and Hippo signaling. The EndMT phenotype of PATJ-depleted cells was associated with the nuclear recruitment of MUC1-C, YAP/TAZ, β-catenin, and ZEB1. Our results suggest that PATJ downregulation 24 h after IS promotes EndMT, an initial step prior to secondary activation of a pro-angiogenic program. This effect is associated with functional independence suggesting that activation of EndMT shortly after stroke onset is beneficial for stroke recovery.

    Yearly attained adherence to Mediterranean diet and incidence of diabetes in a large randomized trial
    (BioMed Central (BMC), 2023-09-29) Martínez-González, Miguel A; Montero, Pedro; Ruiz-Canela, Miguel; Toledo, Estefanía; Estruch, Ramón; Gómez-Gracia, Enrique; Li, Jun; Ros, Emilio; Arós, Fernando; Hernáez, Alvaro; Corella, Dolores; Fiol Sala, Miquel; Lapetra, José; Serra-Majem, Lluis; Pintó, Xavier; Cofán, Montse; Sorli, Jose V; Babio, Nancy; Márquez-Sandoval, Yolanda F; Castañer, Olga; Salas-Salvado, Jordi
    Background: Several large observational prospective studies have reported a protection by the traditional Mediterranean diet against type 2 diabetes, but none of them used yearly repeated measures of dietary intake. Repeated measurements of dietary intake are able to improve subject classification and to increase the quality of the assessed relationships in nutritional epidemiology. Beyond observational studies, randomized trials provide stronger causal evidence. In the context of a randomized trial of primary cardiovascular prevention, we assessed type 2 diabetes incidence according to yearly repeated measures of compliance with a nutritional intervention based on the traditional Mediterranean diet. Methods: PREDIMED (''PREvención con DIeta MEDiterránea'') was a Spanish trial including 7447 men and women at high cardiovascular risk. We assessed 3541 participants initially free of diabetes and originally randomized to 1 of 3 diets: low-fat diet (n = 1147, control group), Mediterranean diet supplemented with extra virgin olive (n = 1154) or Mediterranean diet supplemented with mixed nuts (n = 1240). As exposure we used actual adherence to Mediterranean diet (cumulative average), yearly assessed with the Mediterranean Diet Adherence Screener (scoring 0 to 14 points), and repeated up to 8 times (baseline and 7 consecutive follow-up years). This score was categorized into four groups: < 8, 8-< 10, 10- < 12, and 12-14 points. The outcome was new-onset type 2 diabetes. Results: Multivariable-adjusted hazard ratios from time-varying Cox models were 0.80 (95% confidence interval, 0.70-0.92) per + 2 points in Mediterranean Diet Adherence Screener (linear trend p = .001), and 0.46 (0.25-0.83) for the highest (12-14 points) versus the lowest (< 8) adherence. This inverse association was maintained after additionally adjusting for the randomized arm. Age- and sex-adjusted analysis of a validated plasma metabolomic signature of the Mediterranean Diet Adherence Screener (constituted of 67 metabolites) in a subset of 889 participants also supported these results. Conclusions: Dietary intervention trials should quantify actual dietary adherence throughout the trial period to enhance the benefits and to assist results interpretation. A rapid dietary assessment tool, yearly repeated as a screener, was able to capture a strong inverse linear relationship between Mediterranean diet and type 2 diabetes. Trial registration ISRCTN35739639.

    Background: Dietary patterns can produce an environmental impact. Changes in people's diet, such as the increased consumption of ultra-processed food (UPF) can not only influence human health but also environment sustainability. Objectives: Assessment of the impact of 2-year changes in UPF consumption on greenhouse gas emissions and water, energy and land use. Design: A 2-year longitudinal study after a dietary intervention including 5879 participants from a Southern European population between the ages of 55-75 years with metabolic syndrome. Methods: Food intake was assessed using a validated 143-item food frequency questionnaire, which allowed classifying foods according to the NOVA system. In addition, sociodemographic data, Mediterranean diet adherence, and physical activity were obtained from validated questionnaires. Greenhouse gas emissions, water, energy and land use were calculated by means of the Agribalyse® 3.0.1 database of environmental impact indicators for food items. Changes in UPF consumption during a 2-year period were analyzed. Statistical analyses were conducted using computed General Linear Models. Results: Participants with major reductions in their UPF consumption reduced their impact by -0.6 kg of CO2eq and -5.3 MJ of energy. Water use was the only factor that increased as the percentage of UPF was reduced. Conclusions: Low consumption of ultra-processed foods may contribute to environmental sustainability. The processing level of the consumed food should be considered not only for nutritional advice on health but also for environmental protection. Trial registration: ISRCTN, ISRCTN89898870.

    Trends in Adherence to the Mediterranean Diet in Spanish Children and Adolescents across Two Decades
    (Multidisciplinary Digital Publishing Institute (MDPI), 2023-05-17) Herrera-Ramos, Estefania; Tomaino, Laura; Sanchez-Villegas, Almudena; Ribas-Barba, Lourdes; Gómez, Santiago F; Wärnberg, Julia; Osés, Maddi; González-Gross, Marcela; Gusi, Narcis; Aznar, Susana; Marín-Cascales, Elena; González-Valeiro, Miguel Ángel; Terrados, Nicolás; Tur, Josep A; Segu, Marta; Fito, Montserrat; Homs, Clara; Benavente-Marín, Juan Carlos; Labayen, Idoia; Zapico, Augusto Garcia; Sánchez-Gómez, Jesús; Jiménez-Zazo, Fabio; Alcaraz-Ramón, Pedro Emilio; Sevilla-Sanchez, Marta; Pulgar-Muñoz, Susana; Bouzas, Cristina; Sistac-Sorigué, Clara; Schröder, Helmut; Serra-Majem, Lluis
    Unhealthy dietary habits determined during childhood may represent a risk factor to many of the chronic non-communicable diseases (NCDs) in adulthood. Mediterranean Diet (MD) adherence in children and adolescents (8-16 years) living in Spain was investigated using the KIDMED questionnaire in a comparative analysis of two cross-sectional nationwide representative studies: enKid (1998-2000, n = 1001) and PASOS (2019-2020, n = 3540). Taking into account the educational level of pupils, as well as the characteristics of the place of living, a significant association was found between a KIDMED score ≥ 8 (optimal MD adherence) and primary education as well as residency in an area of <50,000 inhabitants, while living in the southern regions was associated with non-optimal MD adherence (p < 0.001). Participants of the 2019-2020 study showed an increase in the consumption of dairy products (31.1% increase), pasta/rice (15.4% increase), olive oil (16.9% increase), and nuts (9.7% increase), as well as a decreased sweets and candies intake (12.6% reduction). In contrast, a significantly lower MD adherence was found when comparing the 2019-2020 (mean ± SE: 6.9 ± 0.04) and the 1998-2000 study (7.37 ± 0.08); p < 0.001), due to less consumption of fish (20.3% reduction), pulse (19.4% reduction), and fruits (14.9% reduction), and an increased intake of commercial goods/pastries or fast-food intake (both 19.4% increase). The lowest adherence was recorded for adolescents also in the most recent study, where 10.9% of them presented a KIDMED score ≤ 3. This study shows that eating habits are deteriorating among Spanish children and adolescents. Such findings point out the urgency of undertaking strong measures to promote the consumption of healthy, sustainable, and non-ultra-processed food, such as those available in an MD, not only at a scientific and academic level, but also at a governmental one.

    Background: The CohRTA multicenter study aims to characterize patients undergoing a first treatment for alcohol use disorder (AUD). The objective is to analyze sex-specific differences in the comorbidity of AUD when starting the first treatment for the disorder. Methods: A multicenter study was carried out between 2014 and 2021 in 6 public centers in Spain. Sociodemographic characteristics were collected, variables related to alcohol consumption, medical comorbidity according to Cumulative Illness Rating Scale-Substance Abuse (CIRS-SA), antecedent of psychiatric comorbidity, general blood test and screening for drugs in urine. Logistic regression models were used to establish associations. Results: A total of 896 patients (634 M, 262 W) were included. Median age at admission was 48 years [IQR:41ヨ56 years]. Men reported beginning regular alcohol consumption at an earlier age and drank more alcohol. The most frequent medical comorbidities were hepatic, respiratory, vascular and neurological. The median number of affected systems was three, with no differences between men and women. However, depressive disorder was more frequent in women. In the multivariate analysis, women were up to 4 times more likely to have a major depressive disorder, elevated ESR and elevated total cholesterol than men. Men started alcohol consumption earlier, had a higher body mass index (BMI), a higher probability of using cocaine and a higher frequency of GGT and bilirubin alteration than women. Conclusion: Differences by sex were found among individuals beginning first treatment for AUD. These differences must be taken into account when designing specific therapeutic strategies for men and women.

    Plasma metabolite profiles associated with the World Cancer Research Fund/American Institute for Cancer Research lifestyle score and future risk of cardiovascular disease and type 2 diabetes
    (BioMed Central (BMC), 2023-09-16) Rios, Santiago; García-Gavilán, Jesús F; Babio, Nancy; Paz-Graniel, Indira; Ruiz-Canela, Miguel; Liang, Liming; Clish, Clary B; Toledo, Estefanía; Corella, Dolores; Estruch, Ramón; Ros, Emilio; Fitó, Montserrat; Arós, Fernando; Fiol Sala, Miquel; Guasch-Ferré, Marta; Santos-Lozano, José Manuel; Li, Jun; Razquin, Cristina; Martínez-González, Miguel Ángel; Hu, Frank B; Salas-Salvado, Jordi
    Background: A healthy lifestyle (HL) has been inversely related to type 2 diabetes (T2D) and cardiovascular disease (CVD). However, few studies have identified a metabolite profile associated with HL. The present study aims to identify a metabolite profile of a HL score and assess its association with the incidence of T2D and CVD in individuals at high cardiovascular risk. Methods: In a subset of 1833 participants (age 55-80y) of the PREDIMED study, we estimated adherence to a HL using a composite score based on the 2018 Word Cancer Research Fund/American Institute for Cancer Research recommendations. Plasma metabolites were analyzed using LC-MS/MS methods at baseline (discovery sample) and 1-year of follow-up (validation sample). Cross-sectional associations between 385 known metabolites and the HL score were assessed using elastic net regression. A 10-cross-validation procedure was used, and correlation coefficients or AUC were assessed between the identified metabolite profiles and the self-reported HL score. We estimated the associations between the identified metabolite profiles and T2D and CVD using multivariable Cox regression models. Results: The metabolite profiles that identified HL as a dichotomous or continuous variable included 24 and 58 metabolites, respectively. These are amino acids or derivatives, lipids, and energy intermediates or xenobiotic compounds. After adjustment for potential confounders, baseline metabolite profiles were associated with a lower risk of T2D (hazard ratio [HR] and 95% confidence interval (CI): 0.54, 0.38-0.77 for dichotomous HL, and 0.22, 0.11-0.43 for continuous HL). Similar results were observed with CVD (HR, 95% CI: 0.59, 0.42-0.83 for dichotomous HF and HR, 95%CI: 0.58, 0.31-1.07 for continuous HL). The reduction in the risk of T2D and CVD was maintained or attenuated, respectively, for the 1-year metabolomic profile. Conclusions: In an elderly population at high risk of CVD, a set of metabolites was selected as potential metabolites associated with the HL pattern predicting the risk of T2D and, to a lesser extent, CVD. These results support previous findings that some of these metabolites are inversely associated with the risk of T2D and CVD. Trial registration: The PREDIMED trial was registered at ISRCTN (http://www.isrctn.com/ , ISRCTN35739639).

    Perceived Quality of Life Is Related to a Healthy Lifestyle and Related Outcomes in Spanish Children and Adolescents: The Physical Activity, Sedentarism, and Obesity in Spanish Study
    (Multidisciplinary Digital Publishing Institute (MDPI), 2023-12-16) Ródenas-Munar, Marina; Monserrat-Mesquida, Margalida; Gómez, Santiago F; Wärnberg, Julia; Medrano, María; González-Gross, Marcela; Gusi, Narcís; Aznar, Susana; Marín-Cascales, Elena; González-Valeiro, Miguel A; Serra-Majem, Lluis; Pulgar, Susana; Segu, Marta; Fitó, Montse; Torres, Silvia; Benavente-Marín, Juan Carlos; Labayen, Idoia; Zapico, Augusto G; Sánchez-Gómez, Jesús; Jiménez-Zazo, Fabio; Alcaraz, Pedro E; Sevilla-Sanchez, Marta; Herrera-Ramos, Estefanía; Schröder, Helmut; Bouzas, Cristina; Tur, Josep A
    Background: Maintaining a healthy lifestyle is crucial for safeguarding the well-being and quality of life perception, appropriate growth, and development of children and adolescents, while also mitigating the risk of future adult-onset diseases. Objective: To assess associations between perceived quality of life and healthy lifestyle and related outcomes in Spanish children and adolescents. Methods: Cross-sectional analysis of 8-16-year-old children and adolescents (n = 3534) were included in the nationwide study of Physical Activity, Sedentarism, and Obesity in Spanish Youth (PASOS). Data were collected through (1) questionnaires on health-related quality of life (HRQoL), healthy lifestyle outcomes (dietary intake, physical fitness, sleep, and screen time), and (2) anthropometric measurements for weight status assessment. Data were analysed by logistic regression, using the health-related quality of life (HRQoL) as the grouping variable. Results: Participants with a lower HRQoL were those with a lower adherence to the MedDiet and lower achievement of the recommended daily intake of fruit and vegetables. They were also less likely to follow the recommendations for screen time and sleep (with the exception of the weekend) compared to participants with a higher HRQoL. Participants with a lower HRQoL showed a lower healthy weight status and poorer physical fitness than those with a higher HRQoL. Conclusions: Healthy eating habits, healthy weight status (normal weight), appropriate sleep time, physical fitness, and limited screen time play a crucial role in the perceived quality of life in children and adolescents.

    Olive oil consumption, plasma metabolites, and risk of type 2 diabetes and cardiovascular disease
    (BioMed Central (BMC), 2023-12-13) García-Gavilán, Jesús F; Babio, Nancy; Toledo, Estefanía; Semnani-Azad, Zhila; Razquin, Cristina; Dennis, Courtney; Deik, Amy; Corella, Dolores; Estruch, Ramón; Ros, Emilio; Fitó, Montserrat; Arós, Fernando; Fiol Sala, Miquel; Lapetra, José; Lamuela-Raventos, Rosa; Clish, Clary; Ruiz-Canela, Miguel; Martínez-González, Miguel Ángel; Hu, Frank; Salas-Salvado, Jordi; Guasch-Ferré, Marta
    Background: Olive oil consumption has been inversely associated with the risk of type 2 diabetes (T2D) and cardiovascular disease (CVD). However, the impact of olive oil consumption on plasma metabolites remains poorly understood. This study aims to identify plasma metabolites related to total and specific types of olive oil consumption, and to assess the prospective associations of the identified multi-metabolite profiles with the risk of T2D and CVD. Methods: The discovery population included 1837 participants at high cardiovascular risk from the PREvención con DIeta MEDiterránea (PREDIMED) trial with available metabolomics data at baseline. Olive oil consumption was determined through food-frequency questionnaires (FFQ) and adjusted for total energy. A total of 1522 participants also had available metabolomics data at year 1 and were used as the internal validation sample. Plasma metabolomics analyses were performed using LC-MS. Cross-sectional associations between 385 known candidate metabolites and olive oil consumption were assessed using elastic net regression analysis. A 10-cross-validation (CV) procedure was used, and Pearson correlation coefficients were assessed between metabolite-weighted models and FFQ-derived olive oil consumption in each pair of training-validation data sets within the discovery sample. We further estimated the prospective associations of the identified plasma multi-metabolite profile with incident T2D and CVD using multivariable Cox regression models. Results: We identified a metabolomic signature for the consumption of total olive oil (with 74 metabolites), VOO (with 78 metabolites), and COO (with 17 metabolites), including several lipids, acylcarnitines, and amino acids. 10-CV Pearson correlation coefficients between total olive oil consumption derived from FFQs and the multi-metabolite profile were 0.40 (95% CI 0.37, 0.44) and 0.27 (95% CI 0.22, 0.31) for the discovery and validation sample, respectively. We identified several overlapping and distinct metabolites according to the type of olive oil consumed. The baseline metabolite profiles of total and extra virgin olive oil were inversely associated with CVD incidence (HR per 1SD: 0.79; 95% CI 0.67, 0.92 for total olive oil and 0.70; 0.59, 0.83 for extra virgin olive oil) after adjustment for confounders. However, no significant associations were observed between these metabolite profiles and T2D incidence. Conclusions: This study reveals a panel of plasma metabolites linked to the consumption of total and specific types of olive oil. The metabolite profiles of total olive oil consumption and extra virgin olive oil were associated with a decreased risk of incident CVD in a high cardiovascular-risk Mediterranean population, though no associations were observed with T2D incidence. Trial registration: The PREDIMED trial was registered at ISRCTN (http://www.isrctn.com/ , ISRCTN35739639).

    Lung cancer (LC) is the leading cause of cancer deaths, and chronic obstructive pulmonary disease (COPD) can increase LC risk. Metallomics may provide insights into both of these tobacco-related diseases and their shared etiology. We conducted an observational study of 191 human serum samples, including those of healthy controls, LC patients, COPD patients, and patients with both COPD and LC. We found 18 elements (V, Al, As, Mn, Co, Cu, Zn, Cd, Se, W, Mo, Sb, Pb, Tl, Cr, Mg, Ni, and U) in these samples. In addition, we evaluated the elemental profiles of COPD cases of varying severity. The ratios and associations between the elements were also studied as possible signatures of the diseases. COPD severity and LC have a significant impact on the elemental composition of human serum. The severity of COPD was found to reduce the serum concentrations of As, Cd, and Tl and increased the serum concentrations of Mn and Sb compared with healthy control samples, while LC was found to increase Al, As, Mn, and Pb concentrations. This study provides new insights into the effects of LC and COPD on the human serum elemental profile that will pave the way for the potential use of elements as biomarkers for diagnosis and prognosis. It also sheds light on the potential link between the two diseases, i.e., the evolution of COPD to LC.

    Background: Metabolic syndrome (MetS) has become a growing risk factor of some non-communicable diseases. Increase of greenhouse gas emissions affects the planet. Aims: To assess the association between MetS severity and amount of carbon dioxide (CO2) emitted in an adult population. Design: Cross-sectional study (n = 6646; 55-76-year-old-men; 60-75-year-old-women with MetS). Methods: Dietary habits were assessed using a pre-validated semi quantitative 143-item food frequency questionnaire. The amount of CO2 emitted due to the production of food consumed by person and day was calculated using a European database, and the severity of the MetS was calculated with the MetS Severity Score. Results: Higher glycaemia levels were found in people with higher CO2 emissions. The risk of having high severe MetS was related to high CO2 emissions. Conclusions: Low CO2 emissions diet would help to reduce MetS severity. Advantages for both health and the environment were found following a more sustainable diet.

    Mediterranean Diet, Energy Restriction, Physical Activity, and Atherogenicity of Very-Low Density Lipoproteins: Findings from Two Randomized Controlled Trials
    (Wiley, 2023-01) Pérez-Vega, Karla Alejandra; Castañer, Olga; Sanllorente, Albert; Lassale, Camille; Ros, Emilio; Pintó, Xavier; Estruch, Ramon; Salas-Salvado, Jordi; Corella, Dolores; Alonso-Gómez, Ángel M; Serra-Majem, Lluis; Razquin, Cristina; Fiol Sala, Miquel; Lapetra, José; Gómez-Gracia, Enrique; Tinahones, Francisco J; Hernaez, Alvaro; Fito, Montserrat
    Scope: Some very-low density lipoprotein (VLDL) properties may render them more pro-atherogenic. We aimed to assess whether a Mediterranean diet (MedDiet) or an energy-reduced MedDiet with increased physical activity improves them. Methods and results: In a sample of the PREvención con DIeta MEDiterránea (PREDIMED) study, a 1-year intervention with MedDiet with extra-virgin olive oil (n = 89) or nuts (MedDiet-Nuts; n = 79) is compared with a low-fat diet (n = 90). In the PREDIMED-Plus study, a 1-year intervention with energy-reduced MedDiet and physical activity (n = 103) is compared with an ad libitum MedDiet (n = 101). VLDL levels of apolipoprotein C-I, C-III, triglycerides, and cholesterol; the apolipoprotein E-/C-I ratio; and VLDL ex-vivo triglyceride transfer are measured. In PREDIMED participants in both MedDiet groups combined, VLDL apolipoprotein C-III levels are nominally reduced (-0.023 SD units, 95% CI -0.44 to -0.014, p = 0.037). VLDL triglyceride transfer is nominally increased in the MedDiet-Nuts group (+0.39 SD units, 95% CI 0.012-0.78, p = 0.045). In PREDIMED-Plus, no inter-group differences are detected. Conclusions: In older adults at high cardiovascular risk, MedDiet is associated with lower VLDL atherogenicity versus a low-fat diet. No differences are seen after an energy-reduced MedDiet with physical activity.

    Lifestyles, Left Atrial Structure and Function, and Cognitive Decline in Adults with Metabolic Syndrome
    (Multidisciplinary Digital Publishing Institute (MDPI), 2023-09-20) Gonzalez Casanova, Ines; Alonso-Gómez, Ángel M; Romaguera, Dora; Toledo, Estefanía; Li, Linzi; Fortuny Frau, Elena; López, Luis; Ramallal, Raul; Salas-Salvado, Jordi; Tojal-Sierra, Lucas; Castañer, Olga; Alonso, Alvaro
    Evidence supports associations of lifestyle (including diet and physical activity) and weight with cognitive functioning, but the pathways responsible for these associations have not been fully elucidated. Because healthier lifestyles have been associated with better left atrial structure and function, which in turn is associated with better cognitive functioning, we tested the hypothesis that left atrial structure and function is a potential mediator of the association between lifestyle and cognition. We included 476 participants classed as overweight or obese with metabolic syndrome from three centers in Spain. These participants underwent lifestyle assessments and transthoracic echocardiography at baseline and repeated measurements of the Trail Making A test, a measure of executive function, taken at baseline and at the two-year follow-up. We conducted mediation analyses to test if measures of left atrial structure and function mediated associations between adherence to the Mediterranean diet scores, physical activity, and weight at baseline, as well as a two-year change in Trail Making A scores. The analysis did not find an association between these factors and Trail Making A scores, and no indirect effects appeared to be mediated by echocardiographic measurements. The modest sample size in this analysis is a limitation, and larger studies should be conducted to determine potential cardiovascular factors mediating the association between lifestyle and cognition.

    Childhood obesity is a public health problem worldwide. An important determinant of child and adolescent obesity is socioeconomic status (SES). However, the magnitude of the impact of different SES indicators on pediatric obesity on the Spanish population scale is unclear. The aim of this study was to assess the association between three SES indicators and obesity in a nationwide, representative sample of Spanish children and adolescents. A total of 2791 boys and girls aged 8 to 16 years old were included. Their weight, height, and waist circumference were measured. SES was assessed using two parent/legal guardian self-reported indicators (educational level -University/non-University- and labor market status -Employed/Unemployed-). As a third SES indicator, the annual mean income per person was obtained from the census section where the participating schools were located (≥12.731€/<12.731€). The prevalence of obesity, severe obesity, and abdominal obesity was 11.5%, 1.4%, and 22.3%, respectively. Logistic regression models showed an inverse association of both education and labor market status with obesity, severe obesity, and abdominal obesity (all p < 0.001). Income was also inversely associated with obesity (p < 0.01) and abdominal obesity (p < 0.001). Finally, the highest composite SES category (University/Employed/≥12.731€ n = 517) showed a robust and inverse association with obesity (OR = 0.28; 95% CI: 0.16-0.48), severe obesity (OR = 0.20; 95% CI: 0.05-0.81), and abdominal obesity (OR = 0.36; 95% CI: 0.23-0.54) in comparison with the lowest composite SES category (Less than University/Unemployed/<12.731€; n = 164). No significant interaction between composite SES categories and age and gender was found. SES is strongly associated with pediatric obesity in Spain.
