Objective To evaluate disease-free survival of cervical conization prior to radical hysterectomy in patients with stage IB1 cervical cancer (International Federation of Gynecology and Obstetrics (FIGO) 2009). Methods A multicenter retrospective observational cohort study was conducted including patients from the Surgery in Cervical Cancer Comparing Different Surgical Aproaches in Stage IB1 Cervical Cancer (SUCCOR) database with FIGO 2009 IB1 cervical carcinoma treated with radical hysterectomy between January 1, 2013, and December 31, 2014. We used propensity score matching to minimize the potential allocation biases arising from the retrospective design. Patients who underwent conization but were similar for other measured characteristics were matched 1:1 to patients from the non-cone group using a caliper width <= 0.2 standard deviations of the logit odds of the estimated propensity score. Results We obtained a weighted cohort of 374 patients (187 patients with prior conization and 187 non-conization patients). We found a 65% reduction in the risk of relapse for patients who had cervical conization prior to radical hysterectomy (hazard ratio (HR) 0.35, 95% confidence interval (CI) 0.16 to 0.75, p=0.007) and a 75% reduction in the risk of death for the same sample (HR 0.25, 95% CI 0.07 to 0.90, p=0.033). In addition, patients who underwent minimally invasive surgery without prior conization had a 5.63 times higher chance of relapse compared with those who had an open approach and previous conization (HR 5.63, 95% CI 1.64 to 19.3, p=0.006). Patients who underwent minimally invasive surgery with prior conization and those who underwent open surgery without prior conization showed no differences in relapse rates compared with those who underwent open surgery with prior cone biopsy (reference) (HR 1.94, 95% CI 0.49 to 7.76, p=0.349 and HR 2.94, 95% CI 0.80 to 10.86, p=0.106 respectively). Conclusions In this retrospective study, patients undergoing cervical conization before radical hysterectomy had a significantly lower risk of relapse and death.

Objective Based on the SUCCOR study database, our primary objective was to identify the independent clinical pathological variables associated with the risk of relapse in patients with stage IB1 cervical cancer who underwent a radical hysterectomy. Our secondary goal was to design and validate a risk predictive index (RPI) for classifying patients depending on the risk of recurrence. Methods Overall, 1116 women were included from January 2013 to December 2014. We randomly divided our sample into two cohorts: discovery and validation cohorts. The test group was used to identify the independent variables associated with relapse, and with these variables, we designed our RPI. The index was applied to calculate a relapse risk score for each participant in the validation group. Results A previous cone biopsy was the most significant independent variable that lowered the rate of relapse (odds ratio [OR] 0.31, 95% confidence interval [CI] 0.17-0.60). Additionally, patients with a tumor diameter >2 cm on preoperative imaging assessment (OR 2.15, 95% CI 1.33-3.5) and operated by the minimally invasive approach (OR 1.61, 95% CI 1.00-2.57) were more likely to have a recurrence. Based on these findings, patients in the validation cohort were classified according to the RPI of low, medium, or high risk of relapse, with rates of 3.4%, 9.8%, and 21.3% observed in each group, respectively. With a median follow-up of 58 months, the 5-year disease-free survival rates were 97.2% for the low-risk group, 88.0% for the medium-risk group, and 80.5% for the high-risk group (p < 0.001). Conclusion Previous conization to radical hysterectomy was the most powerful protective variable of relapse. Our risk predictor index was validated to identify patients at risk of recurrence.

Introduction NGAL has recently been studied as a biomarker in the diagnostic context of pediatric acute appendicitis (PAA), although existing series are scarce and have limited sample sizes. Materials and methods A prospective observational study was designed to validate serum NGAL as a diagnostic tool in PAA. This study included 215 patients, divided into 3 groups: (1) patients undergoing major outpatient surgery (n = 63), (2) patients with non-surgical abdominal pain in whom a diagnosis of PAA was excluded (n = 53) and (3) patients with a confirmed diagnosis of PAA (n = 99). Patients in group 3 were divided into complicated or uncomplicated appendicitis. In 201 patients, a serum sample was obtained at the time of diagnosis and NGAL concentration was determined by ELISA. The Kolmogorov-Smirnov test was used to assess normality. Comparative statistical analyses were performed using the Mann-Whitney U test, the Kruskal-Wallis test and the Fisher's exact test. To calculate the discriminative ability of the molecule, the area under the receiver-operating characteristic curves (AUC) was calculated. A p value < 0.05 established statistical significance. Results Median (interquartile range) of serum NGAL values were 38.88 (27.15-48.04) ng/mL (group 1), 51.84 (37.33-69.80) ng/mL (group 2) and 65.06 (50.50-86.60) ng/mL (group 3). The AUC (group 2 vs 3) was 0.642 (95% CI 0.542-0.741) (p < 0.001) and the best cutoff point was found to be at 40.97 ng/mL, with a sensitivity of 89% and a specificity of 34.6%. No statistically significant differences in serum NGAL values were found between patients with uncomplicated PAA and those with complicated PAA. Conclusions This prospective validation study with a large sample size confirms that the diagnostic yield of NGAL in the context of PAA is only moderate, and therefore, it should not be used as a unique diagnostic tool. Furthermore, NGAL is not a valid biomarker to discern between uncomplicated and complicated PAA.

Objective: To assess whether higher adherence to the traditional Mediterranean diet (MedDiet) was associated with lower consumption of ultra-processed foods (UPF) and lower free sugar intake. Design: Cross-sectional analysis of baseline information among participants in the SENDO project, a Spanish paediatric cohort. Dietary information was collected through a semi-quantitative FFQ. Food items were classified according to the NOVA classification. Adherence to the MedDiet was evaluated through the KIDMED index. Setting: Spain. Participants: Three hundred eight-six children (52 % boys) with a mean age of 5 center dot 3 years old (sd 1 center dot 0) were included in the analysis. Results: 74 center dot 4 % of the children had moderate adherence to the MedDiet (mean KIDMED score: 5 center dot 9 points; sd 1 center dot 7) and overall, 32 center dot 2 % of the total energy intake came from UPF. Each two additional points in the KIDMED score was associated with 3 center dot 1 % (95 % CI 2 center dot 1, 4 center dot 0) lower energy intake from UPF. Compared to those with low adherence to the MedDiet, children with medium and high adherence reported 5 center dot 0 % (95 % CI 2 center dot 2, 7 center dot 7) and 8 center dot 5 % (95 % CI 5 center dot 2, 11 center dot 9) lower energy intake from UPF, respectively. We also found that 71 center dot 6 % of the variability in free sugar intake was explained by the variability in UPF consumption. Conclusions: Adherence to the traditional MedDiet was inversely associated with energy intake from UPF. Furthermore, most of the variability in free sugar intake was explained by the variability of UPF consumption. Public health strategies are needed to strengthen the adherence to the MedDiet in pre-schoolers while regulating the production, marketing and advertising of UPF.

The purpose of this study was to assess the effect of physical activity (PA) changes, measured by accelerometry, on telomere length (TL) in pediatric patients with abdominal obesity after a lifestyle intervention. One hundred and twenty-one children (7-16 years old) with abdominal obesity were randomized to the intervention (a moderately hypocaloric Mediterranean diet) or the usual care group (standard pediatric recommendations) for 22 months (a 2 month intensive phase and a subsequent 20 month follow-up). Both groups were encouraged to accumulate an extra 200 min/week of PA. TL was measured by MMqPCR. Data were analyzed in 102 subjects after 2 months and 64 subjects at the first 10 months of follow-up. Light PA level decreased in both groups after 12 months of intervention. At month 2, moderate to vigorous PA (MVPA) increased in the intervention group (+5.4 min/day, p = 0.035) and so did sedentary time in the usual care group (+49.7 min/day, p = 0.010). TL changes were positively associated (p < 0.050) with metabolic equivalents (METs), MVPA level, and number of steps, and were inversely associated with sedentary and light PA levels in the intervention group after the intensive phase. In conclusion, favourable changes in PA levels in the intensive phase of a lifestyle intervention could contribute to TL maintenance in a pediatric population with abdominal obesity. Novelty Changes in physical activity levels had a direct effect on telomere length, a biomarker of cellular aging and oxidative stress. PA advice based on The American College of Sports Medicine included in this intervention is easy to implement in primary care.

Introduction: the preschool stage is a critical period for teaching and modeling healthy habits to positively influence children's health and wellbeing throughout their lifetime. Objectives: to evaluate the association between parental attitudes towards their offspring's dietary habits in Spanish children aged 4 to 7 years participating in the Follow-up of Children for Optimal Development (SENDO) project. Methods: we defined an index to measure information on parental attitudes towards their offspring's diet (0 to 8 points), and another one to measure children's actual dietary habits (0 to 19 points). A higher score meant healthier attitudes and healthier habits, respectively. Information was collected through an online questionnaire completed by parents. We calculated crude and multivariable-adjusted odds ratios (OR) and 95 % confidence intervals (CI) for children's healthy dietary habits associated with parental scores in the parental attitudes index. Generalized estimation equations (GEE) were used to account for intra-cluster correlation between siblings. Results: a total of 423 preschoolers (52.3 % boys, mean age 5.3 years) were included in the analyses. Half of the children (51 %) reported unhealthy dietary habits, whereas 56 % of parents reported high adherence to the healthy eating index. Compared to those in the lowest category, the children whose parents were in the highest category in the parental attitudes index showed significantly higher odds of having healthy dietary habits (OR: 2.91; 95 % CI: 1.30-6.53, p for trend = 0.004). Conclusions: our results support a direct association between parental attitudes and their offspring's dietary habits, suggesting that public health interventions aimed at improving children's dietary habits should shift from the individual- to a family-based approach.

Aim: The association between caesarean delivery and the risk of overweight/obesity in the offspring has been previously reported using conventional measures of association (relative risks or odds ratios). We aimed at refining the existing evidence by calculating the marginal effect of the exposure and estimating the unmeasured residual confounding. Methods: In the 'SEguimiento del Nino para un Desarrollo Optimo' Project, a dynamic multipurpose paediatric cohort study, we collected information from parents through self-administered online questionnaires. We estimated the offspring's risk of overweight/obesity at age 4-6 years, associated with the type of delivery through marginal effect of the exposure. Unmeasured residual confounding was assessed using the E-value. Results: Among 407 participants (mean-age: 5.0 years (standard deviation: 0.9)), 86 (21.1%) were born by caesarean delivery. Children born by caesarean delivery had higher odds of overweight/obesity than those born vaginally. Subgroup analyses showed similar results. The multivariable adjusted marginal effect showed that caesarean delivery was associated with an 8.0% (95% confidence interval: 0.2-15.7) absolute increase in the prevalence of overweight/obesity. The estimated residual confounding showed an E-value of 4.03, higher than the OR obtained for all the confounding factors we accounted for. Conclusions: Caesarean delivery was associated with an 8% absolute increase in the risk of overweight/obesity that is very unlikely explained by residual confounding.

Introduction: The consumption of ultra-processed products (UP) is associated with many diseases in the adult, such as arterial hypertension, diabetes, or asthma. Objective: To determine whether the consumption of UP in children is associated with wheezing respiratory diseases (asthma or bronchitis/recurrent wheezing). Material and methods: A cross-sectional study was conducted within the Follow-up of the Child for Optimal Development ?SENDO? project (an open, multidisciplinary and multiple outcome study of Spanish children). The consumption of UP was calculated using semi-quantitative questionnaires on the frequency of food consumption. The foods were grouped according the NOVA classification, and the daily consumption was estimated along with the percentage of kilocalories from the UP. The exposure was grouped into "high" and "low" from the median consumption. Odds ratios and 95% confidence intervals were calculated for wheezing respiratory diseases associated with the high consumption UP, using low consumption as a reference. Crude and multi-adjusted estimators were calculated, and mixed regression models were used to take into account the correlation between siblings. Results: In the 513 children studied (51.8% males, mean age 5.2 years), the mean consumption of UP was 446.76 g/day, representing 39.9% of the total calories ingested. A high consumption of UP was associated with an increase of 87% in the prevalence of wheezing respiratory diseases (OR 1.87; 95% CI 1.01-3.45). It was found that a higher consumption of UP multiplied by 2.12 (95% CI 1.10-4.05) the prevalence of bronchitis/recurrent wheezing. Conclusions: The results of this study show a direct relationship between UP consumption and the prevalence of wheezing diseases in children.

We present a 5-year-old girl who accidentally crushed an insect of the coleoptera family walking barefoot and secondarily developed an exogenous acral pigmentation. The lesions resolved spontaneously within a few weeks. Proper identification of the insect and a detailed physical examination were key to avoiding unnecessary invasive diagnostic tests.

Introducción: existe controversia sobre si la lactancia materna (LM) prolongada puede ser un factor de riesgo de caries. La LM se recomienda hasta al menos los dos años y tiene demostrados beneficios sobre la salud, incluida la bucodental. Repasamos la evidencia científica y presentamos los resultados de nuestra cohorte. Métodos: cohorte prospectiva, abierta y multipropósito de niños de 4-5 años, cuyos padres responden a cuestionarios autorreferidos acerca de hábitos nutricionales y estilo de vida. Análisis retrospectivo de prevalencia de caries según duración de LM. Ajustamos por edad, sexo, raza, conocimientos nutricionales y actitudes dietéticas de los padres, adhesión a la dieta mediterránea, ingesta energética total y de azúcar. Resultados: se alcanzó un tamaño muestral de 370 participantes, 50 de los cuales había tenido, al menos una caries. La LM hasta los 12 meses se asociaba con un menor riesgo de caries, pero la LM de más de 12 meses se asociaba con un riesgo mayor (odds ratio [OR]: 2,75; intervalo de confianza del 95% [IC 95]: 1,397 a 5,44; p = 0,003). La ingesta energética total o la de azúcar no resultaron ser confusores importantes para la asociación estudiada. La adhesión a dieta mediterránea puede tener un efecto protector, hace falta más investigación al respecto. Conclusiones: existe una asociación directa estadísticamente significativa entre la LM de más de 12 meses y el riesgo de caries. Sin embargo, la LM hasta los 12 meses es un factor protector. Los resultados obtenidos son consistentes con la literatura médica existente.

Objective: To test the validity of parent-reported birth information obtained through an online, self-administered questionnaire. Method: The SENDO project is a prospective and dynamic paediatric cohort of Spanish children aged 4 to 6 years old at recruitment. Objective data from medical birth records were compared to parent-reported data getting intra-class correlation coefficients (ICC) for quantitative variables and weighted Kappa Index for qualitative ones. Percentage of responders and of total agreement was also evaluated. Results: Parental response rate was over 99% for birth weight and gestational age and 76% for birth length. ICC for birth weight was 0.95 (95% confidence interval [95%CI]: 0.94-0.96) and 0.78 (95%CI: 0.73-0.83) for birth length, both showing very high correlations. The total agreement percentage for gestational age was 97%, and Kappa weighted index was 0.90 (95%CI: 0.89-0.90), showing a very high agreement as well. Conclusions: We found high correlations and excellent agreement in parent-reported birth data 4 to 6 years after delivery. Our results show parent-reported birth data, especially birth weight, are valid for use in epidemiological research.

Objective: To assess the association between pregestational BMI and offspring's risk of overweight/obesity after accounting for the most important confounders, especially maternal smoking habit. Design: Prospective cohort study. Setting: The Seguimiento Universidad de Navarra (SUN) study is a prospective cohort of Spanish graduates with more than 22 000 participants nationwide. Recruitment started in 1999, and it is permanently open. Data on diet, lifestyle and clinical diagnoses are collected at baseline and every 2 years. Participants: Women from the SUN cohort who reported at least one pregnancy during follow-up (n 3496) were invited to this study. Among them, 1527 agreed to participate and completed an additional more detailed online questionnaire on their pregnancy history and their offspring's nutritional status. Results: After excluding 165 children, we analysed data of 2791 participants born to 1485 mothers and observed that each 5 kg/m(2) increase in pregestational BMI was associated with a 0 center dot 22 (95 % CI 0 center dot 15, 0 center dot 29) higher z-score in offspring's BMI and higher risk of overweight/obesity (multivariable-adjusted relative risk (RR) 1 center dot 57 (95 % CI 1 center dot 39, 1 center dot 77)) in childhood or adolescence. Furthermore, we observed stronger association in children born to smoker mothers (RR 1 center dot 91; 95 % CI 1 center dot 48, 2 center dot 46) than from non-smoker mothers (RR 1 center dot 51; 95 % CI 1 center dot 31, 1 center dot 73) (P-for interaction = 0 center dot 02). Conclusions: We found a synergistic interaction between pregestational BMI and maternal smoking habit on offspring's z-score of the BMI and in their risk of overweight/obesity. Although further research is needed to analyse dose-response relationships, these findings reinforce the importance of promoting healthy lifestyles in pregnant women in order to prevent childhood obesity.

Introduction Comprehensive updated information on cervical cancer surgical treatment in Europe is scarce. Objective To evaluate baseline characteristics of women with early cervical cancer and to analyze the outcomes of the ESGO quality indicators after radical hysterectomy in the SUCCOR database. Methods The SUCCOR database consisted of 1272 patients who underwent radical hysterectomy for stage IB1 cervical cancer (FIGO 2009) between January 2013 and December 2014. After exclusion criteria, the final sample included 1156 patients. This study first described the clinical, surgical, pathological, and follow-up variables of this population and then analyzed the outcomes (disease-free survival and overall survival) after radical hysterectomy. Surgical-related ESGO quality indicators were assessed and the accomplishment of the stated recommendations was verified. Results The mean age of the patients was 47.1 years (SD 10.8), with a mean body mass index of 25.4 kg/m(2) (SD 4.9). A total of 423 (36.6%) patients had a previous cone biopsy. Tumor size (clinical examination) <2 cm was observed in 667 (57.7%) patients. The most frequent histology type was squamous carcinoma (794 (68.7%) patients), and positive lymph nodes were found in 143 (12.4%) patients. A total of 633 (54.8%) patients were operated by open abdominal surgery. Intra-operative complications occurred in 108 (9.3%) patients, and post-operative complications during the first month occurred in 249 (21.5%) patients, with bladder dysfunction as the most frequent event (119 (10.3%) patients). Clavien-Dindo grade III or higher complication occurred in 56 (4.8%) patients. A total of 510 (44.1%) patients received adjuvant therapy. After a median follow-up of 58 months (range 0-84), the 5-year disease-free survival was 88.3%, and the overall survival was 94.9%. In our population, 10 of the 11 surgical-related quality indicators currently recommended by ESGO were fully fulfilled 5 years before its implementation. Conclusions In this European cohort, the rate of adjuvant therapy after radical hysterectomy is higher than for most similar patients reported in the literature. The majority of centers were already following the European recommendations even 5 years prior to the ESGO quality indicator implementations.

Objective: Quantify the impact of reducing the consumption of red/processed meats on cardiovascular mortality and all-cause mortality of the Spanish adult population based in 5 revisions published. Participants and main measurements: We defined exposure as consumption of >= 3 servings/week of red or processed meats and considered four possible scenarios of exposed population (30%-60%). Based on data from the Spanish National Statistics Institute, we calculated the weighted mortality between 40 and 80 years. Using the relative risks (RR) and 95% confidence intervals (CI) published by the referred revisions (RR= 0.88; IC 95%: 0.84-0.93 for all-cause mortality and RR =0.92; IC 95%: 0.90-0.93 for cardiovascular mortality), we calculated the expected mortality rate in both exposed and unexposed categories. By multiplying these rates by the number of exposed individuals, we estimated the attributable number of yearly deaths. Results: If 60% of the population was exposed, with a 95% CI, the number of cardiovascular deaths that could be averted each year if population consumed < 3 servings/week of red or processed meats was between 2.112 and 3.055. If was exposed that 30%, the difference in the yearly number of potentially averted deaths was between 1.079 and 1.577. Conclusions: Even under the most conservative assumption, the benefit, at the population level, of reducing red or processed meats consumption < 3 servings/week on cardiovascular mortality is important. The conclusions of the recently published reviews contradicted their own results and contributed to a state of confusion that can create substantial harm for public health.

Objective: to analyze the validity of self-reported somatometry data through a self-reported online questionnaire. Method: the SENDO project (Follow-up of Children for Optimal Development) is a prospective, dynamic pediatric cohort. Participants are recruited when they are between 4 and 6 years old, and followed annually through an online questionnaire. In a subsample of 82 participants, we compared the anthropometric information reported in the baseline questionnaire with the direct measurements collected by the investigating staff. To do this, we calculated the intraclass correlation index (ICC) and the Bland-Altman coefficient. Results: the ICC was 0.96 (95 % confidence interval [CI]: 0.94-0.98 for weight; 0.95 (95 % CI: 0.92-0.96) for height; 0.75 (95 % CI: 0.64-0.86) for waist circumference; and 0.84 (95 % CI: 0.76-0.89) for hip circumference. In relation to the indices calculated from these measurements, we found an ICC of 0.84 (95 % CI: 0.77-0.90) for body mass index; 0.46 (95 % CI: 0.27-0.62) for waist-hip ratio; and 0.59 (95 % CI: 0.43-0.72) for waist-height index. The Bland-Altman index ranged from 3.7 % for weight to 8.5 % for body mass index. Conclusions: we found a high correlation and concordance between the data collected in the physical exam and those reported by the parents. Our results indicate that the anthropometric measures provided by parents, especially those with which they are most familiar, are valid and can be used in epidemiological research.

Importance Cesarean delivery is associated with an increased risk of childhood obesity in offspring. However, whether this increased risk also includes obesity-associated conditions remains unclear. Objective To evaluate the association of birth by cesarean delivery with offspring's risks of obesity and type 2 diabetes in adulthood. Design, Setting, and Participants This prospective cohort study compared the incidence of obesity and type 2 diabetes between birth by cesarean delivery and vaginal delivery among 33 226 women participating in the Nurses' Health Study II who were born between 1946 and 1964, with follow-up through the end of the 2013-2015 follow-up cycle. Participants' mothers provided information on mode of delivery and pregnancy characteristics. Participants provided information every 2 years on weight and diagnosis of type 2 diabetes. Relative risks of obesity and type 2 diabetes were estimated using log-binomial and proportional hazards regression accounting for maternal body mass index and other confounding factors. Statistical analysis was performed from June 2017 to December 2019. Exposure Birth by cesarean delivery compared with birth by vaginal delivery. Main Outcomes and Measures Risk of obesity and incidence of type 2 diabetes. Results At baseline, the participants' mean (SD) age was 33.8 (4.6) years (range, 24.0-44.0 years). A total of 1089 of the 33 226 participants (3.3%) were born by cesarean delivery. After 1 913 978 person-years of follow-up, 12 156 (36.6%) women were obese and 2014 (6.1%) had received a diagnosis of type 2 diabetes. Women born by cesarean delivery were more likely to be classified as obese and to have received a diagnosis of type 2 diabetes during follow-up. The multivariable-adjusted relative risk of obesity among women born by cesarean vs vaginal delivery was 1.11 (95% CI, 1.03-1.19). The multivariable-adjusted hazard ratio for type 2 diabetes among women born by cesarean vs vaginal delivery was 1.46 (95% CI, 1.18-1.81); this association remained significant after additional adjustment for participant's own body mass index (relative risk, 1.34 [95% CI, 1.08-1.67]). These associations persisted when analyses were restricted to women at low risk of cesarean delivery based on maternal characteristics. Conclusions and Relevance This study suggests that women born by cesarean delivery may have a higher risk than women born by vaginal delivery of being obese and developing type 2 diabetes during adult life.

Background Most studies assessing the association between caesarean delivery (CD) and childhood overweight/obesity have failed to account for important confounders, such as maternal prepregnancy body mass index (BMI) or the indication of the CD. Furthermore, within-family analyses have reported contradictory results. We aimed at evaluating the association between CD and offspring's risk of overweight/obesity while adjusting for important confounders and accounting for correlations between siblings. Methods Women in the 'Seguimiento Universidad de Navarra' cohort provided structured information regarding their pregnancy history and their children's health through online cross-sectional questionnaires. We calculated adjusted differences in BMI z-score and risk ratios (RR) for offspring's overweight/obesity associated with CD, with hierarchical models to account for correlations between siblings. We also performed a within-family analysis in 341 siblings who were discordant in delivery mode, using conditional multivariable logistic regression. Results Among the 2791 children analysed, those born by CD had higher average BMI z-scores (difference: 0.17; 95% CI 0.07 to 0.27) and higher risk of overweight/obesity (RR: 1.32, 95% CI 1.05 to 1.65) than children born vaginally. The association did not differ by maternal characteristics or offspring's age strata, and the results were consistent in sensitivity analyses. Furthermore, within-family analysis showed that children born by CD had 2.67-fold higher risk of overweight/obesity (95% CI 1.10 to 5.12) than their peers born vaginally. Conclusion Children born by CD have higher average BMI z-scores and higher risk of overweight/obesity than children born vaginally. The consistency of these findings across multiple approaches to address potential residual confounding likely suggests a true biological effect.

Dietary polyphenol intake is associated with improvement of metabolic disturbances. The aims of the present study are to describe dietary polyphenol intake in a population with metabolic syndrome (MetS) and to examine the association between polyphenol intake and the components of MetS. This cross-sectional analysis involved 6633 men and women included in the PREDIMED (PREvencion con DIeta MEDiterranea-Plus) study. The polyphenol content of foods was estimated from the Phenol-Explorer 3.6 database. The mean of total polyphenol intake was 846 +/- 318 mg/day. Except for stilbenes, women had higher polyphenol intake than men. Total polyphenol intake was higher in older participants (>70 years of age) compared to their younger counterparts. Participants with body mass index (BMI) >35 kg/m(2) reported lower total polyphenol, flavonoid, and stilbene intake than those with lower BMI. Total polyphenol intake was not associated with a better profile concerning MetS components, except for high-density lipoprotein cholesterol (HDL-c), although stilbenes, lignans, and other polyphenols showed an inverse association with blood pressure, fasting plasma glucose, and triglycerides. A direct association with HDL-c was found for all subclasses except lignans and phenolic acids. To conclude, in participants with MetS, higher intake of several polyphenol subclasses was associated with a better profile of MetS components, especially HDL-c.

Background Minimally invasive surgery in cervical cancer has demonstrated in recent publications worse outcomes than open surgery. The primary objective of the SUCCOR study, a European, multicenter, retrospective, observational cohort study was to evaluate disease-free survival in patients with stage IB1 (FIGO 2009) cervical cancer undergoing open vs minimally invasive radical hysterectomy. As a secondary objective, we aimed to investigate the association between protective surgical maneuvers and the risk of relapse. Methods We obtained data from 1272 patients that underwent a radical hysterectomy by open or minimally invasive surgery for stage IB1 cervical cancer (FIGO 2009) from January 2013 to December 2014. After applying all the inclusion-exclusion criteria, we used an inverse probability weighting to construct a weighted cohort of 693 patients to compare outcomes (minimally invasive surgery vs open). The first endpoint compared disease-free survival at 4.5 years in both groups. Secondary endpoints compared overall survival among groups and the impact of the use of a uterine manipulator and protective closure of the colpotomy over the tumor in the minimally invasive surgery group. Results Mean age was 48.3 years (range; 23-83) while the mean BMI was 25.7 kg/m(2)(range; 15-49). The risk of recurrence for patients who underwent minimally invasive surgery was twice as high as that in the open surgery group (HR, 2.07; 95% CI, 1.35 to 3.15; P=0.001). Similarly, the risk of death was 2.42-times higher than in the open surgery group (HR, 2.45; 95% CI, 1.30 to 4.60, P=0.005). Patients that underwent minimally invasive surgery using a uterine manipulator had a 2.76-times higher hazard of relapse (HR, 2.76; 95% CI, 1.75 to 4.33; P<0.001) and those without the use of a uterine manipulator had similar disease-free-survival to the open surgery group (HR, 1.58; 95% CI, 0.79 to 3.15; P=0.20). Moreover, patients that underwent minimally invasive surgery with protective vaginal closure had similar rates of relapse to those who underwent open surgery (HR, 0.63; 95% CI, 0.15 to 2.59; P<0.52). Conclusions Minimally invasive surgery in cervical cancer increased the risk of relapse and death compared with open surgery. In this study, avoiding the uterine manipulator and using maneuvers to avoid tumor spread at the time of colpotomy in minimally invasive surgery was associated with similar outcomes to open surgery. Further prospective studies are warranted.

Introduction: currently, it is important to determine whether food frequency questionnaires (FFQ) are valid tools to collect information on usual diet in children. Objective: we evaluated the reproducibility and validity of the semi-quantitative FFQ used in a Spanish cohort of children aged 4-7 years. Methods: to explore its reproducibility, parents filled a 138-item FFQ at baseline (FFQ-0) and then one year later (FFQ-1). To explore its validity, the FFQ-1 was compared with four weighed 3-day dietary records (DRs) that were used as standard of reference. To estimate associations we calculated deattenuated Pearson's correlation coefficients to correct for season-to-season variability, and the Bland-Altman index. We also calculated the weighted kappa index and assessed participant's gross misclassification across quintiles. We analyzed data from 67 (for reproducibility) and 37 (for validity) children aged 4-7 years old, recruited by the pilot study of the SENDO project. Results: regarding reproducibility, we found mean Bland-Altman indexes of 0-10.45 % for nutrients and 1.49 %-10.45 % for foods. The adjusted r ranged between 0.29 and 0.71, and between 0.27 and 0.74 for nutrients and foods, respectively. Regarding validity, we found mean Bland-Altman indexes of 0 %-16.22 % and 0 %-10.81 % for nutrients and for food groups, respectively. The deattenuated r ranged between 0.38 and 0.81 for nutrients, and between 0.53 and 0.68 for foods. The weighted kappa index for agreement across quintiles ranged from 54.1 to 85.1 for nutrients, and from 55.4 to 78.4 for food groups. Conclusions: our results showed acceptable levels of both reproducibility and validity, and that the ad-hoc developed FFQ is a valid tool for assessing usual diet in Spanish preschoolers.

Several meta-analyses including a small number of cohorts showed inverse associations between the Mediterranean Diet (MedDiet) and risk of stroke. However, it remains unclear whether such a relation varies by region of the study population or by major subtypes of stroke. We searched PubMed and EMBASE databases for relevant studies and we further included unpublished results from the Singapore Chinese Health Study (N=57,078) and the Seguimiento Universidad de Navarra (SUN) study (N=12,670). We used a random-effects model to calculate summary relative risk (RR) with 95% confidence intervals (CI) of stroke for each 4-point increment of the MedDiet score, roughly corresponding to the difference between extreme quintiles of the MedDiet score among participants of the included studies. The final analyses included 20 prospective cohort studies involving 682,149 participants and 16,739 stroke cases. The summary RRs for each 4-point increment of the MedDiet score were 0.84 (95% CI 0.81-0.88; I-2=11.5%) for all combined, 0.76 (95% CI 0.65-0.89) for studies in Mediterranean populations and 0.86 (95% CI 0.83-0.89) for those in non-Mediterranean populations. Lower risk of stroke associated with higher MedDiet score also was observed in the analyses stratified by study population and methodological characteristics including study risk of bias, version of the MedDiet index, and definition of moderate alcohol consumption. The MedDiet was similarly associated with lower risk of ischemic stroke (RR 0.86, 95% CI 0.81-0.91; nine studies) and hemorrhagic stroke (RR 0.83, 95% CI 0.74-0.93; eight studies). Our meta-analysis suggests that adhering to the Mediterranean diet was associated with lower risk of stroke in both Mediterranean and non-Mediterranean populations, and for both ischemic stroke and hemorrhagic stroke risk.

BackgroundPhysical activity (PA) is associated with changes in body composition that affect insulin sensitivity and leptin levels. Few studies have assessed the effect of lifestyle interventions on changes in objectively measured PA levels in obese children. To evaluate the effects of a multidisciplinary lifestyle intervention on anthropometric indices, biochemical parameters and accelerometer measured PA in abdominal obese children.MethodsA randomized control trial was performed in 106 children and adolescents with abdominal obesity. Participants were randomly assigned to usual or intensive care group for 8-week. PA was measured by accelerometry over four days including, at least, two weekdays in all participants. Both groups were encouraged to accumulate an extra time of 200min per week in their PA.ResultsAt baseline, 75% of subjects do not fulfill the WHO recommendation of being more than 60min/day on moderate-to-vigorous PA (MVPA). The intensive care group achieved a significant reduction in anthropometric indexes compared to the usual care but no significant change was found in biochemical or PA parameters. Both groups achieved a significant reduction in light PA. Interestingly, intensive care participants significantly increased MVPA in 5.5min/day. Moreover, an inverse association between changes in MVPA and leptin levels was found.ConclusionThe two lifestyle intervention reduced anthropometric indexes and lowered light PA in abdominal obese children. No significant differences were observed between intensive care and usual care in regard to PA. Intensive care participants significantly increase physical activity (MVPA) and, changes in MVPA were inversely associated with changes in leptin levels after the intervention.

Introduction: Navarra is a Community that presents a great geographical and climatic variety, which results in a wide food supply. Objectives: to review the typical gastronomy of Navarra, as well as the available evidence on dietary patterns, nutritional profile and health indicators of Navarra population. Results: Navarra has 7 Protected Designations of Origin and 6 Protected Geographical Indications. Its gastronomic identity is mainly associated with vegetables, lamb, veal and local sausages, which is reflected in dietary patterns. Comparatively, Navarra population consumes more vegetables and fresh fruits, but also has a frequent and excessive intake of meat (especially red) and sausages. The studies available on nutritional profile show high intakes of proteins and fats in the adult population, and inadequacy in some micronutrients in children. In the national context, Navarra has lower rates of overweight, obesity and sedentariness in the adult population, and there is a downward trend in the prevalence of childhood obesity. Conclusions: the food and gastronomic offer of Navarra is varied and with a great prominence of vegetables, although dietary patterns can be improved. To achieve a healthy and sustainable diet, it is essential to promote culinary knowledge and skills from an early age.

Research question: Studies in rodents have shown that paternal folate intake prior to conception is associated with pregnancy and offspring outcomes. The aim of this study was to assess whether those associations might apply to humans as well. Design: Between 2007 and 2017, the study prospectively analysed data from 108 couples participating in a preconception cohort of couples undergoing fertility treatment using their own gametes, whose treatment resulted in 113 pregnancies during the course of the study. Paternal and maternal preconception folate intake was assessed using a validated food frequency questionnaire. Linear mixed models were used to assess whether paternal preconception folate intake was associated with gestational age at delivery and gestational age-specific birthweight, while accounting for correlated data and potential confounders. Results: In a multivariable-adjusted model, a 400 ¿g/day increase in preconception paternal folate intake was associated with a 2.6-day longer gestation (95% confidence interval 0.8-4.3) after adjusting for potential confounders, including maternal folate intake. Similar associations were found for folate from food and supplements. Maternal folate intake was not associated with gestational age at delivery. Neither paternal nor maternal folate intake was associated with gestational-age-specific birthweight. Conclusions: Higher paternal preconception folate intake was associated with slightly longer gestation among live births achieved through assisted reproduction. The results suggest that preconception exposures of the father may have an impact on the health of his offspring, and therefore that preconception care should shift from a woman-centric to a couple-based approach.

Introducción: la leche y los derivados lácteos son alimentos importantes para el desarrollo. Sin embargo, la creencia de que se asocian con infecciones respiratorias está provocando que se limite su consumo o se sustituya por bebidas vegetales. El objetivo del estudio fue analizar si el consumo de lácteos se asocia con determinadas infecciones respiratorias en la infancia. Material y métodos: estudio transversal con 169 voluntarios de entre 4 y 7 años. Información recogida mediante cuestionarios en papel. Información dietética recogida mediante cuestionario de frecuencia de consumo de alimentos semicualitativo de 151 ítems. Se valoró la asociación del consumo de leches, quesos y yogures con determinadas enfermedades respiratorias (otitis media aguda, sinusitis, mastoiditis, neumonía), comparando dos categorías de consumo definidas a partir de la mediana de cada alimento, mediante regresión logística multivariable. Resultados: no se encontraron asociaciones entre el consumo de lácteos y las enfermedades respiratorias analizadas (odds ratio: 0,85; intervalo de confianza del 95%: 0,44 a 1,64]). Al analizar cada lácteo por separado, se encontró una asociación inversa entre el consumo de quesos y las enfermedades respiratorias en conjunto (odds ratio: 0,50; intervalo de confianza del 95%: 0,26 a 0,98), pero no para cada una de las infecciones por separado (otitis media aguda ni neumonía). No se encontró asociación significativa con los desenlaces para ningún otro derivado lácteo (leche o yogures). Conclusiones: los resultados no apoyan una asociación directa entre el consumo de leche y derivados con infecciones respiratorias en la infancia. Con los datos actuales no está justificado restringir el consumo de leche o derivados en niños en edad escolar

Coffee is one of the most widely consumed drinks around the world, while depression is considered the major contributor to the overall global burden of disease. However, the investigation on coffee consumption and depression is limited and results may be confounded by the overall dietary pattern. We assessed the relationship between coffee intake and the risk of depression, controlling for adherence to the Mediterranean diet. We studied 14,413 university graduates of the Seguimiento Universidad de Navarra' (SUN) cohort, initially free of depression. We evaluated coffee consumption using a validated food-frequency questionnaire (FFQ). Incident depression cases were adjudicated only if the participant met two criteria simultaneously: (a) validated physician-diagnosed depression together with (b) new onset of habitual antidepressant use. Both criteria were needed; participants meeting only one of them were not classified as cases. Participants who drank at least four cups of coffee per day showed a significantly lower risk of depression than participants who drank less than one cup of coffee per day (HR: 0.37 (95% CI 0.15-0.95)). However, overall, we did not observe an inverse linear dose-response association between coffee consumption and the incidence of depression (p for trend = 0.22).

Background: The relation of coffee consumption with total mortality is controversial, because the available evidence is still inconsistent. Objective: This study aimed to assess this association in a highly educated, middle-aged Mediterranean cohort. Design: We analyzed data from 201,055 person-years of follow-up arising from 19,888 participants. Coffee consumption was obtained at baseline with the use of a previously validated semi-quantitative food-frequency questionnaire. Information on mortality was ascertained by permanent contact with the "Seguimiento Universidad de Navarra" (SUN) participants and their families, postal authorities, and consultation of the National Death Index. We used Cox regression models to estimate HRs and 95% CIs for mortality according to baseline total coffee consumption adjusted for potential confounders. Sex, age, and baseline adherence to the Mediterranean diet were considered as potential effect modifiers. Results: Among the 19,888 participants, 337 died. Overall, in the multivariable adjusted analysis, we found a 22% lower risk of all-cause mortality for each 2 additional cups of total coffee per day (HR: 0.78; 95% CI: 0.66, 0.93). This association was stronger for participants aged >= 55 y (HR: 0.67; 95% CI: 0.52, 0.86) than for younger participants, who showed no significant association (P-interaction = 0.002). Conclusion: In a Mediterranean cohort, we found an inverse linear association between total coffee consumption and the risk of all-cause mortality that was strongest among participants older than 54 y.

Although survival of elderly myeloma patients has significantly improved there is still a subset of patients who, despite being fit and achieving optimal responses, will die within 2 years of diagnosis due to myeloma progression. The objective of this study was to define a scoring prognostic index to identify this group of patients. We have evaluated the outcome of 490 newly diagnosed elderly myeloma patients included in two Spanish trials (GEM2005-GEM2010). Sixty-eight patients (13.8%) died within 2 years of diagnosis (early deaths) due to myeloma progression. Our study shows that the use of simple scoring model based on 4 widely available markers (elevated LDH, ISS 3, high risk CA or >75 years) can contribute to identify up-front these patients. Moreover, unsustained response (<6 months duration) emerged as one important predictor of early myeloma-related mortality associated with a significant increase in the risk of death related to myeloma progression. The identification of these patients at high risk of early death is relevant for innovative trials aiming to maintain the depth of first response, since many of them will not receive subsequent lines of therapy.

Parental nutrition knowledge and attitudes play a fundamental role in their children's food knowledge. However, little is known about their influence on their children's diet quality and micronutrient intake. Thus, we aimed to assess the association of parental nutrition knowledge and healthy-eating attitudes with their children's adherence to the Mediterranean dietary pattern and micronutrient adequacy. Parental healthy-eating attitudes and knowledge of the quality of their child's diet as well as anthropometric, lifestyle, and nutrient intake characteristics were recorded with a basal questionnaire that included a 140-item-food frequency-questionnaire. A total of 287 pre-school children were included in the analyses. Intake adequacy was defined using the Estimated Average Requirements (EAR) cut-off point method. We developed a parental nutrition knowledge and healthy-eating attitudes scores and evaluated whether they were independently associated with 1) children's inadequate intake (probability of failing to meet 3 EAR) of micronutrients, using logistic regression analyses, and 2) children's diet quality (adherence to the Mediterranean Diet according to a Mediterranean Diet Quality Index for children and adolescents, the KIDMED index), using multiple linear regression models. A higher score in the parental healthy-eating attitudes score was associated with lower risk of failing to meet 3 EAR compared with the reference category (odds ratio (OR): 0.3; 95% confidence interval (CI) 0.12-0.95; p for trend: 0.037) and a higher adherence to the Mediterranean diet in the most adjusted model ( coefficient: 0.34; 95% CI 0.01-0.67; p for trend: 0.045). Our results suggest a positive association of parental healthy-eating attitudes with nutritional adequacy and diet quality in a sample of Spanish preschoolers. Public health strategies should focus on encouraging parental healthy-eating attitudes rather than simply educating parents on what to feed their children, recognizing the important influence of parental behavior on children's practices.

BACKGROUND: Inflammation related molecules such as tumor necrosis factor-¿ (TNF-¿), interleukin 6 (IL-6), and cardiotrophin-1 (CT-1) are highly expressed in obese individuals and could partly explain some comorbidities associated to obesity. In obese children, lifestyle interventions are able to lower inflammation and reduce cardiovascular risk factors associated with obesity. The aim of the present work was to study changes in inflammation-related molecules serum and peripheral blood mononuclear cells (PBMC) transcript levels after a 10-week lifestyle intervention in obese children and asses their potential association with glucose metabolism. METHODS: Twenty-three obese children (mean age 11.5 years; 48% males) underwent a 10-week lifestyle not controlled intervention trial. Anthropometric and biochemical measurements were analyzed. Transcript analysis for CT-1, IL-6, and TNF-¿ in PBMC were performed by RT-PCR. Serum cytokine levels were also measured at baseline and after 10-weeks. RESULTS: Participants achieved a significant reduction in body adiposity (0.34 decrease in body mass index-standard deviation), total cholesterol, and glucose levels after 10-weeks. A Significant decrease in serum TNF-¿ and C reactive protein (CRP) were observed. CT-1 transcript levels were significantly reduced (P = .005) after lifestyle intervention, and these changes were significantly correlated with changes in serum CT-1 levels (r = 0.451; P = .031). In multiple regression analysis baseline CT-1 transcript levels were positively associated with final insulin (R2 = 0.506; P = .035) and HOMA-IR values (R2 = 0.473; P = .034). CONCLUSIONS: We reported that serum CRP, TNF-¿, as well as PBMC CT-1 transcript levels were reduced after lifestyle intervention in obese children. More studies are needed to clarify the role of inflammation-related molecules in glucose metabolism.

Background and aims: The oxidation of low-density lipoprotein (LDL) cholesterol particles is an early atherogeninic event. Obese pediatric populations have higher levels of oxidized LDL (oxLDL) than normal weight children. The aim of this study was to evaluate the effect of a weight loss program on the biochemical profile and oxLDL levels in Spanish obese children and adolescents. Methods: Forty obese children (mean age 11 years, 51% boys) followed a 10-week weight loss program. They were dichotomized at the median of body mass index-standard deviation score (BMI-SDS) change, as high (HR) and low responders (LR) after the intervention. The intervention included a moderate energy-restricted diet, nutritional education, and family involvement. Anthropometric and biochemical measurements were performed at the beginning and during the follow up. A cardiometabolic risk score (CMS) was calculated considering metabolic risk factors. Results: Higher baseline oxLDL levels were associated with a higher CMS in obese children (P<.001). After the intervention, oxLDL significantly decreased in the HR group. Moreover, a positive correlation between changes in oxLDL and BMI-SDS (r=0.385, P=.015) was found after the weight loss program. Interestingly, multiple-adjusted regression models showed an association between changes in total cholesterol [B: 0.127, 95% confidence interval (CI): 0.06 to 0.20] and LDL-cholesterol (B: 0.173, 95% CI: 0.08 to 0.26) with changes in oxLDL. Conclusions: Higher baseline oxLDL levels were associated with a higher CMS in obese children. After the weight loss program, a decrease in oxLDL levels was found in HR subjects and the oxLDL levels were associated with BMI-SDS and cholesterol levels.

Smoking is a serious global public health concern that has been related to many chronic diseases. However, the effect of smoking on eye disorders has been less studied. The aim of this cohort study was to assess the association between current tobacco smokers and the risk of developing glaucoma and furthermore to evaluate the relationship between passive or former smokers and glaucoma. In this prospective and dynamic cohort, 16,797 participants initially who were found not to have glaucoma were followed up for a median of 8.5 years. Validated data on lifestyle, including tobacco consumption, were assessed at baseline. Information about new diagnosis of glaucoma was collected by follow-up questionnaires every 2 years. The outcome was the incidence of self-reported glaucoma during the follow-up. A subsample was used to validate the glaucoma diagnosis. During the 8.5 years of follow-up, 184 new glaucoma cases were identified. Current smokers had a significantly higher risk of glaucoma compared to participants who had never smoked after controlling for potential confounders (Hazard ratio [HR] 1.88 [95% coefficient interval (CI): 1.26-2.81]; P=0.002). A nonsignificant increased risk was found among former smokers (HR 1.27 [95% CI: 0.88-1.82]; P=0.198). When we assessed the exposure as per the number of cigarette pack-years, a dose-response relationship between pack-years and the risk of glaucoma was found (HR for the 5th quintile versus the 1st quintile: 1.70 [95% IC: 1.10-2.64], P for trend, 0.009). However, no relationship was found between passive smokers and glaucoma. (HR 0.67 [95% CI: 0.37-1.21]; P=0.189). Our results suggest a direct association between current smokers and the incidence of glaucoma. In particular, this association was related to the number of pack-years, which was not found in the case of former smokers nor in the case of passive smokers.

Background: The associations between dietary fat and cardiovascular disease have been evaluated in several studies, but less is known about their influence on the risk of diabetes. Objective: We examined the associations between total fat, subtypes of dietary fat, and food sources rich in saturated fatty acids and the incidence of type 2 diabetes (T2D). Design: A prospective cohort analysis of 3349 individuals who were free of diabetes at baseline but were at high cardiovascular risk from the PREvencion con DIeta MEDiterranea (PREDIMED) study was conducted. Detailed dietary information was assessed at baseline and yearly during the follow-up using a food frequency questionnaire. Multivariable Cox proportional hazards models were used to estimate T2D HRs and 95% CIs according to baseline and yearly updated fat intake. Results: We documented 266 incident cases during 4.3 y of follow-up. Baseline saturated and animal fat intake was not associated with the risk of T2D. After multivariable adjustment, participants in the highest quartile of updated intake of saturated and animal fat had a higher risk of diabetes than the lowest quartile (HR: 2.19; 95% CI: 1.28, 3.73; and P-trend = 0.01 compared with HR: 2.00; 95% CI: 1.29, 3.09; and P-trend < 0.01, respectively). In both the Mediterranean diet and control groups, participants in the highest quartile of updated animal fat intake had anw2-fold higher risk of T2D than their counterparts in the lowest quartile. The consumption of 1 serving of butter and cheese was associated with a higher risk of diabetes, whereas whole-fat yogurt intake was associated with a lower risk. Conclusions: In a Mediterranean trial focused on dietary fat interventions, baseline intake of saturated and animal fat was not associated with T2D incidence, but the yearly updated intake of saturated and animal fat was associated with a higher risk of T2D. Cheese and butter intake was associated with a higher risk of T2D, whereas whole-fat yogurt intake was associated with a lower risk of T2D.

Observational studies have found a protective effect of vitamin C on cardiovascular health. However, results are inconsistent, and residual confounding by fiber might be present. The aim of this study was to assess the association of vitamin C with the incidence of cardiovascular disease (CVD) and cardiovascular mortality (CVM) while accounting for fiber intake and adherence to the Mediterranean dietary pattern. We followed up 13,421 participants in the Seguimiento Universidad de Navarra (University of Navarra follow-up) (SUN) cohort for a mean time of 11 years. Information was collected at baseline and every two years through mailed questionnaires. Diet was assessed with a validated semi-quantitative food frequency questionnaire. Incident CVD was defined as incident fatal or non-fatal myocardial infarction, fatal or non-fatal stroke, or death due to any cardiovascular cause. CVM was defined as death due to cardiovascular causes. Events were confirmed by physicians in the study team after revision of medical records. Cox proportional hazard models were fitted to assess the associations of (a) energy-adjusted and (b) fiber-adjusted vitamin C intake with CVD and CVM. We found energy-adjusted vitamin C was inversely associated with CVD and CVM after adjusting for several confounding factors, including fiber from foods other than fruits and vegetables, and adherence to the Mediterranean dietary pattern. On the other hand, when vitamin C was adjusted for total fiber intake using the residuals method, we found a significant inverse association with CVM (HR (95% confidence interval (CI)) for the third tertile compared to the first tertile, 0.30 (0.12-0.72), but not with CVD in the fully adjusted model.

Background: Among adults, the Mediterranean dietary pattern (MDP) is inversely related to body mass index (BMI). Data are lacking on adherence to the MDP among youth in the United States and whether the MDP is related to weight change in that group. Objective: To assess whether adherence to the MDP was associated with BMI change among adolescents. To examine temporality, we studied the association between baseline and 2-3-year changes in adherence to the MDP with concurrent changes in BMI, as well as subsequent changes in BMI over a 7-year period. Methods: We prospectively followed 6002 females and 4916 males in the Growing Up Today Study II, aged 8-15 years in 2004, living across United States. Data were collected by questionnaire in 2004, 2006, 2008 and 2011. Dietary intake was assessed by the Youth/Adolescent Questionnaire. The KidMed Index was derived to measure the adherence to the MDP. We used generalized estimating equations with repeated measures within subjects to assess the association between MDP and BMI change. Results: A two-point increment in the KidMed Index was independently associated with a lower gain in BMI (-0.04 kg m(-2); P=0.001). A greater increase in adherence to the KidMed Index was independently related to a lower gain in BMI in both the concurrent (P-for-trend<0.001) and the subsequent period (P-for-trend=0.002). Conclusions: Adherence to MDP was inversely associated with change in BMI among adolescents. Two-year improvement in adherence to MDP was independently associated with less steep gain in the BMI in both the concurrent and the subsequent period.

Background: The role of yogurt consumption in the development of metabolic syndrome (MetS) is not fully understood and the available epidemiologic evidence is scarce. The aim of our study was to assess the association between total, whole-fat, or low-fat yogurt consumption and the risk of developing MetS.Methods: Yogurt consumption was assessed at baseline through a 136-item validated FFQ. MetS was defined following the harmonized definition for MetS according to the AHA and the IDF criteria. Logistic regression models were used.Results: During the first 6-y of follow-up of the SUN cohort, 306 incident cases of MetS were identified. Frequent consumption [>= 875 g/week (>= 7 servings/week) versus <= 250 g/week (2 servings/week)] of total, whole-fat and low-fat yogurt consumption showed non-significant inverse associations with MetS [OR = 0.84 (95% CI: 0.60-1.18); 0.98 (95% CI: 0.68-1.41); and 0.63 (95% CI: 0.39-1.02) respectively]. Only one component of the MetS, central adiposity, was inversely associated with total and whole-fat yogurt consumption [OR = 0.85 (95% CI: 0.74-0.98) and 0.85 (95% CI: 0.73-0.99) respectively]. In the joint assessment of exposure to total yogurt consumption and fruit consumption, those in the highest category of total yogurt consumption, and having a high fruit consumption (above the median = 264.5 g/day) exhibited a significantly lower risk of developing MetS [OR = 0.61 (95% CI: 0.38-0.99)] compared with those in the lowest category of total ...

We evaluated the effectiveness of oral sodium citrate versus intravenous (IV) sodium bicarbonate for CI-AKI prophylaxis as well as their influence on kidney injury biomarkers. Material and Methods: A randomized, controlled, single-center study including 130 hospitalized patients (62.3% men), who were randomized to receive sodium bicarbonate (1/6 men, 3 ml/kg/h for 1 h; n = 43), oral sodium citrate (75 ml/10 kg divided into 4 doses; n = 43) or nonspecific hydration (n = 44) before contrast administration, was conducted. Serum creatinine and kidney injury biomarkers (cystatin C, neutrophil gelatinase-associated lipocalin, interleukin-8, F2-isoprostanes and cardiotrophin-1 [CT-1]) were assessed. Results: Incidence of CI-AKI was 9.2% with no differences found between hydration groups: 7.0% in sodium bicarbonate group, 11.6% in oral sodium citrate group and 9.1% in the nonspecific hydration group. Urinary creatinine and urinary CT-1/creatinine ratio decreased 4 h after contrast infusion (p < 0.001), but none of the biomarkers assessed were affected by the treatments. Conclusions: There were no differences in hydration with oral sodium citrate and IV sodium bicarbonate for the prophylaxis of CI-AKI. Therefore, oral hydration represents a safe, inexpensive and practical method for preventing CI-AKI in low-risk patients. No effect on biomarkers for kidney injury could be demonstrated.

Objective: To assess the association between the consumption of sugar-sweetened carbonated beverages (SSCB) and obesity in children and adolescents from Navarra (Spain). Design: We used a matched case-control study design. The exposure, SSCB consumption (1 serving: 200 ml), was measured with a previously validated FFQ. Anthropometrical measures were taken using standardized protocols. The outcome, obesity, was defined as BMI above the age- and sex-specific 97th percentile according to the Spanish reference charts. In the analysis we used conditional logistic regression. Potential confounders were controlled using a multivariable model. Setting: Subjects were recruited in the paediatric departments of the Universidad de Navarra Clinic and the Navarra Hospital Complex, and in three primary health centres of Navarra. Controls were recruited when attending for a routine medical examination or vaccination. Subjects: One hundred and seventy-four obese children and 174 individually sex- and age-matched controls, 52·87 % boys, with a mean age of 11·6 years. Exclusion criteria were dietary interventions, exposure to hormone treatment, development of secondary obesity due to endocrinopathy and serious intercurrent illness. Results: Independently of other factors, high consumption of SSCB (>4 servings/week) was significantly associated with obesity (OR = 3·46; 95 % CI 1·24, 9·62; P = 0·01). Besides, each additional daily serving of SSCB was associated with a 69 % relative increase in the risk of obesity (OR = 1·69; 95 % CI 1·04, 2·73; P = 0·03). Conclusions: We found a strong and significant association between SSCB consumption and obesity risk. Our results suggest a monotonic dose-response linear shape for this association in children and adolescents (P for trend = 0·02).

Introducción: La alta de prevalencia de obesidad infantil en España y sus posibles consecuencias hacen de esta enfermedad un problema prioritario de salud pública. Objetivo: Valorar, mediante un estudio epidemiológico analítico de casos y controles, la asociación entre la composición en macronutrientes de la dieta y la obesidad en una muestra de niños y adolescentes navarros de 5,5 a 18,8 años. Método: Se reclutaron 178 casos, niños y adolescentes obesos (índice de masa corporal > percentil 97) en Navarra. Los controles fueron emparejados individualmente según edad y sexo. Las medidas antropométricas fueron tomadas por personal entrenado utilizando métodos estandarizados. Se realizaron entrevistas individuales para recoger información sobre la frecuencia de consumo de alimentos mediante un cuestionario previamente validado a partir del que se calculó la ingesta de macronutrientes (hidratos de carbono, proteínas y grasas) y de los subtipos de grasas. Estos resultados se dividieron en quintiles de macronutrientes ajustados por ingesta energética total. Se realizó una regresión logística condicional para estimar odds ratios ajustadas de obesidad para cada uno de los cuatro quintiles superiores de consumo, usando el quintil inferior como referencia. Resultados: La composición de macronutrientes de la dieta era similar en casos y controles, excepto para las grasas poliinsaturadas, que se asociaron inversamente a la obesidad (p tendencia lineal < 0,01) con una odds ratio ajustada de 0,34 (IC 95%: 0,15 a 0,77) para el quinto quintil. Conclusiones: Nuestros resultados sugieren una asociación inversa entre una mayor ingesta de grasas poliinsaturadas y el riesgo de obesidad.

Introduction: The high prevalence of obesity among Spanish children and adolescents has become an important public health problem. Objective: To assess the association between dietary macronutrient intake and obesity in a case-control study of children and adolescents (aged 5.5 to 18.8) from Navarra. Methods: Cases were 178 obese children (body mass index > 97th percentile), from Navarra. Controls were individually matched by sex and age. Anthropometric data were collected by trained personal using standardized procedures. Personal interviews were performed to collect previously validated semiquantitative food frequency questionnaires (FFQs). From these FFQs we calculated the intake of macronutrients (carbohydrates, proteins and fats) and types of fatty acids. Energy-adjusted macronutrient intake was divided into quintiles. Conditional logistic regression was used and confounder factors were taken into account. Results: The macronutrient composition of the diet was similar between cases and controls, except for polyunsaturated fatty acids (PUFA) intake, which was significantly inversely associated with obesity (p for trend < 0.01), with adjusted odds ratio = 0.34 (95% CI: 0.15 to 0.77) for the fifth versus the first quintile. Conclusions: An inverse and significant association between PUFA intake and obesity was found in this case-control study.
