RESUMO

OBJECTIVES: Novel findings indicate links between unhealthy lifestyles and depression based on active inflammatory processes. Thus, identifying participants with poor habits could reveal differences in trends of incident depression. This study aimed to examine the association between an objective lifestyle assessment, as measured by the Lifestyle and Well-Being Index (LWB-I), and incident depression in healthy participants of a Spanish cohort. STUDY DESIGN: This was a longitudinal analysis of a subsample of 10,063 participants from the Seguimiento Universidad de Navarra cohort study. METHODS: Group comparisons and Cox proportional hazard models were conducted using the LWB-I, which categorizes the sample into groups with healthy and unhealthy lifestyles and well-being. The main outcome was incident depression as well as secondary outcomes. RESULTS: Those classified to the transition category of LWB-I were associated with a hazard ratio of 0.67 (95% confidence interval: 0.52-0.87), and those in the excellent category showed a hazard ratio of 0.44 (95% confidence interval: 0.33-0.58), which in both groups reflects a significantly lower risk of incident depression compared with the group including those classified in the poor LWB-I level. Moreover, the available sensitivity analyses concerning time of depression diagnosis or antidepressant treatment further supported the role of nutrition and physical activity on incident depression. Interestingly, throughout the follow-up, incident depression was inversely related to healthier daily habits as measured by the LWB-I. CONCLUSIONS: A global assessment of lifestyles such as the LWB-I provides valuable insight into the complex relationship between lifestyle factors and their link to depression risk.

RESUMO

OBJECTIVES: This study aimed to assess the impact of the latest smoke-free legislation on hospital admission rates due to smoking-related diseases in Spain. STUDY DESIGN: A retrospective cohort study was conducted to evaluate changes in hospital admission rates for cardiovascular, respiratory diseases, and smoking-related cancer in Valencia, Spain, during the period 1995-2013. Law 28/2005 and then law 42/2010 prohibited smoking in bars and restaurants as well as playgrounds and access points to schools and hospitals. METHODS: General population data by age and sex were obtained from the National Institute of Statistics census. Data on hospital admissions were obtained from the Minimum Basic Data Set. Diagnoses were codified according to the International Classification of Diseases-9th revision. Data from all hospitals of the Valencian Community from 1995 to 2013 were analysed. Trend analyses in the periods before and after the approval of the 2005 law were conducted using least-squares linear regression models. RESULTS: Adjusted hospital admission rates per 100,000 inhabitants for cardiovascular diseases significantly decreased after the 2005 Law (from 550.0/100,000 in 2005 to 500.5/100,000 in 2007), with a further decrease (to 434.6/100,000) in 2013, after the 2010 Law. Reductions in hospital admissions were seen in men and women, although declining trends were more marked in men. Hospital admission rates for respiratory diseases showed a reduction of a lower magnitude, whereas for smoking-related cancer admissions there was a slight decline only among men. CONCLUSIONS: The Spanish comprehensive smoking ban resulted in a remarkable reduction of the adjusted rate of hospital admissions mainly associated to cardiovascular diseases. The decrease in the number of persons requiring in-patient care is relevant and may be viewed as an improvement of the public's health.

RESUMO

BACKGROUND AND AIMS: Polyphenol-rich diets have been associated with reduced risk of cardiovascular disease (CVD). However, few prospective epidemiological studies have examined the relationship between classes of ingested polyphenols and risk of CVD. Our aim was to evaluate the association between polyphenol intake and risk of major cardiovascular events in a prospective Spanish cohort. METHODS AND RESULTS: We included 17,065 university graduates (60.7% women, mean age: 37.2 years, age range: 20-89) followed-up for a mean of 10.1 years. Polyphenol intake was assessed at baseline using a validated semi-quantitative 136-item food frequency questionnaire and matching food consumption data with the Phenol-Explorer database. Cox proportional hazards models were used to estimate the adjusted hazard ratios (HR) and 95% confidence intervals (95% CI) for incident cardiovascular events (myocardial infarction, stroke or cardiovascular death). Cherries, chocolate, coffee, apples, and olives were the major sources of variability in polyphenol intake. Participants with higher flavonoids intake (fifth quintile) had a 47% lower incidence of cardiovascular events compared to those in the lowest quintile (HR: 0.53, 95% CI: 0.29-0.98; P for trend = 0.09) after adjusting for potential confounders. The results were non-significant for other polyphenol types. CONCLUSION: The intake of flavonoids showed an inverse association with risk of cardiovascular events in a prospective cohort of Spanish middle-aged adult university graduates. REGISTRATION NUMBER FOR CLINICAL TRIALS: NCT02669602 in Clinical Trials.

RESUMO

OBJECTIVE: To determine the prevalence of Adverse Events related to Medication (AEM) in hospitals of the Valencian Community in the 2005-2013 study period, and to describe the associated risk factors and their impact. METHODS: This study is based on data and methodology of the Study of Prevalence of Adverse Events in hospitals (EPIDEA), since its inception in 2005 until 2013. AEM produced in each year were analyzed. RESULTS: We identified 344 AEM that occurred in 337 patients, among 35,103 patients studied, giving a prevalence of patients with AEM of 0.96% (IC95% 0.89-1.07). The most prevalent intrinsic risk factors for AEM were hypertension, diabetes and cancer. The most prevalent extrinsic risk factors were peripheral venous catheter, urinary catheter and central venous catheter. Therapeutic groups most frequently involved were systemic antibiotics, cardiovascular drugs and antineoplastics. The 61.17% of AEM was classified as moderate, followed by 27.18% as mild and 11.65% as severe. The 33.99% of EAM caused increase of the patient's stay and 39.90% of EAM caused the re-entry of patient. The 58.5% of AEM were avoidable. Mild AEM were avoidable in 46.3%, moderate AEM were avoidable in 60.3% and severe AEM were in 75% (p = 0.013). CONCLUSIONS: The prevalence of patients with AEM in hospitals of the Community of Valencia for the period 2005- 2013 was 0.96%. More than half of AEM were preventable, and preventability increases significantly with the severity of the event.

RESUMO

OBJECTIVE: The construction of a predictive model that improves the estimation of the fetal weight (EFW). STUDY DESIGN: a comparative, descriptive study. One hundred forty pregnant women were recruited at two-stage sample in health department in Spain. They were classified in four groups depending on the pre-gestational BMI. Fetal weight at term was estimated by ultrasound at 33-35 weeks (EFW40w) by one gynecologist. A regression model was created with the variables that reacted to the newborn's weight, symphysis-fundal height (SFH), EFW40w, gestational age (GA), ferritin level and cigarettes smoked. RESULTS: A multivariate model was created for the NW group to estimate the fetal weight (EFWme), resulting in R2=0.727 (p<0.001). The differences of the averages obtained between EFW40w and EFWme, with the newborn's weight were significant (p<0.001). EFWme underestimates birth weight by 0.07 g (mean error 0.53%), and EFW40w overestimates it by 300.89 g (mean error 10.12%). In order to evaluate the predictive model and verify the predictions we used the Bland-Altman analysis. The average error in estimating the birth weight with EFWme was 1.94% underestimating the result, whereas the ultrasound error overestimated the result 10.93%. CONCLUSION: The multivariate model created for the NW group improves the accuracy of the ultrasound.

RESUMO

OBJECTIVES: No study that analyzes how the investigators who work in the Spanish hospitals perceived and evaluate the current research system has been performed. This work, carried out by the Scientific Forum of the Lilly Foundation, aims to improve the level of information on the research activity performed in the hospitals. SUBJECTS AND METHODS: By means of a «self-administered¼ interview made up of 34 items and aimed at physicians and other research professionals who work in the Spanish hospitals (272 surveyed), 3 questions were analyzed: a) general situation of biomedical research in Spain; b) administration of available resources: need for better resources, and c) evaluation and giving priority to biomedical research. RESULTS: The use of the data has shown strengths in the system such as the initiatives to promote research through contracts with FIS and post-residency (7.6/10 points); the beneficial effects of research and care quality (7.3/10); or support of the pharmaceutical industry through the sponsoring of clinical trials (6.9/10). However, it has also shown that there are some weaknesses in the organization of the centers, as for example, those referring to the differentiated allocation of the care cost of the research activity (5.1/10); to the coordination between them and the health care centers (2.8/10); to the integration and organization among care, teaching and research (3.6/10); and to decide the priorities (5.2/10) and evaluation (5.2/10) of the research activities. Furthermore, the value of the research as a fundamental activity of the hospitals is emphasized (4.7/10). CONCLUSIONS: The investigators surveyed consider that biomedical research in recent decades in the hospital setting has significantly improved and has had a positive effect in the number of publications. The subjects surveyed consider that research should have greater institutional support and recognition, and a more translational orientation, which would be translated into better quality of life of the citizens and registry of patents.

RESUMO

Introducción: El objetivo de este estudio fue determinar prospectivamente la etiología vírica de la gastroenteritis aguda (GEA) en lactantes hospitalizados, así como describir las características clínicas de los principales virus. Pacientes y métodos: Desde octubre de 2006 hasta marzo de2007, se realizó el seguimiento de todos los niños de 1-23 meses de edad hospitalizados en tres hospitales, desde el momento de la admisión hasta las 72 horas tras el alta, para detectarla presencia de GEA. Se analizó una muestra de heces de los niños con GEA para la detección de rotavirus, calicivirus (norovirus y sapovirus), astrovirus y adenovirus mediante transcripción inversa y reacción en cadena de la polimerasa. Resultados: De un total de 1.576 pacientes hospitalizados, se pudo realizar el seguimiento de 1.300 (82,5%), que han constituido nuestra cohorte de estudio. Un total de 242 niños tuvieron GEA (un 18,6% de la cohorte), obteniéndose muestra de heces de 217 (89,7%). En 91 casos (42%) se detectaron rotavirus, en 72 norovirus (33,2%), en 7 astrovirus (3,2%) y en2 adenovirus; no se detectó sapovirus en ningún caso. Trece niños (6%) presentaron infecciones mixtas por dos o más virus, y 32 (14,7%) resultaron negativos para todos los virus analizados. En los casos de GEA por norovirus se observa menor apatía y pérdida de peso que en los casos de rotavirus, pero mayorporcentaje de heces con sangre.Conclusiones: Los virus son una causa frecuente de GEA enlos niños menores de 2 años hospitalizados; el principal virus hallado es el rotavirus, seguido del norovirus. Debido a las escasas diferencias clínicas observadas entre rotavirus y norovirus, es necesaria su determinación analítica para su diferenciación (AU)


Introduction: The objective of this study was to determine prospectively the viral etiology of acute gastroenteritis (AGE) in hospitalized weaning babies and describe the clinical characteristics of the principal virus detected. Patients and methods: All children aged 1 to 23 months admitted to 3 hospitals during October 2006-March 2007 were followed for the presence of AGE from the time of hospital admission until 72 hours after hospital discharge. A stool sample of children with AGE was tested for calicivirus (norovirus and sapovirus), rotavirus, adenovirus and astrovirus by RT-PCR. Results: Of the 1,576 hospitalized children, 1,300 (82.5%)were fully monitored being our study cohort. A total of 242children had AGE (18.6% of the cohort) and stool samples from217 children were obtained (89.7%). In 91 cases (42%) were positive to rotavirus, 72 (33.2%) to norovirus, 7 (3.2%) to astrovirus, and in 2 to adenovirus, not detecting sapovirus in any case, 13 children (6%) showed mixed infections by two or more viruses and 32 (14.7%) cases were negative for the analyzed virus. Norovirus AGE have less apathy and weight loss than thecases of rotavirus but a higher percentage of stools with blood. Conclusions: The viruses are a frequent cause of AGE among the hospitalized children of less than 2 years of age being rotavirus the principal virus found followed by norovirus. Few clinical differences were observed between rotavirus and norovirus and analytical determination is necessary for their differentiation (AU)

RESUMO

OBJECTIVE: The objective of the present study was to determine the dietary patterns of a Mediterranean cohort and relate them to the observed patterns of beverage consumption. DESIGN: Prospective cohort study. Dietary habits were assessed with a semi-quantitative FFQ validated in Spain. A principal components factor analysis was used to identify dietary patterns and to classify subjects according to their adherence to these patterns. The association between adherence to each dietary pattern and beverage consumption was assessed cross-sectionally. In a longitudinal analysis (2-year follow-up), the relationship between adherence to the baseline dietary patterns and the likelihood of changing alcohol consumption was ascertained. SETTING: The SUN (Seguimiento Universidad de Navarra) study is conducted in Spain. SUBJECTS: In total, 15 073 university graduates were included in the analyses. RESULTS: Two major dietary patterns were identified. We labelled them as 'Western dietary pattern' (WDP) and 'Mediterranean dietary pattern' (MDP). Higher adherence to the WDP was associated with higher consumption of carbonated beverages and whole-fat milk (P for trend <0.001), while higher adherence to the MDP was associated with higher consumption of decaffeinated coffee, orange juice, other natural juices, diet carbonated drinks, low-fat milk and bottled water (P for trend <0.001). Participants with higher adherence to the WDP were less likely to decrease their alcohol consumption during follow-up (OR between extreme quintiles = 0.68; 95 % CI 0.56, 0.84). By contrast, participants with higher adherence to the MDP were less likely to increase their alcohol consumption (OR = 0.66, 95 % CI 0.46, 0.95). CONCLUSION: In this cohort of university graduates, a healthier dietary pattern was associated with a healthier pattern of beverage consumption.

RESUMO

OBJECTIVE: To compare the anthropometric, alimentary, nutritional and lipid profiles and global diet quality of Spanish children according to saturated fat intake. DESIGN: This was a cross-sectional study. Food data were collected using a food-frequency questionnaire. SUBJECTS AND METHODS: The sample included 1112 children of both sexes, aged between 6 and 7 years, selected by means of random cluster sampling in schools. The plasma lipid profile included measurements of low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides, apolipoprotein A1 (apoA1) and apolipoprotein B (apoB). Global diet quality was evaluated by the Dietary Variety Index (DVI) and the Healthy Eating Index (HEI). RESULTS: Energy intake, DVI and HEI of children from the lower quartile of saturated fat intake (LL) were higher (P<001) than in the remaining children (UL). However, there were no significant differences in average height or weight between groups. The UL children had lower intakes of meat, fish, vegetables, fruits and olive oil and a higher intake of dairy products (P<0.001). The intakes of fibre, vitamins C, D, B6, E and folic acid were higher in the LL children, who had lower intakes of vitamin A and calcium. The ratios LDL-C/HDL-C and apoB/apoA1 were lower (P=0.04) in the LL children (1.87 and 0.52, respectively) than in the UL children (2.02 and 0.54, respectively). CONCLUSIONS: The growth rate of children does not seem to be affected by the level of saturated fat intake. Furthermore, at the levels of intake observed in this study, diets with less saturated fat are associated with better alimentary, nutritional and plasma lipid profiles.

RESUMO

The purpose of this study was to evaluate exposure conditions and acute health effects in subjects participating in the Prestige oil spill cleanup activities and the association between these and the nature of the work and use of protection devices in the regions of Asturias and Cantabria (Spain). The sample comprised 400 subjects in each region, selected from a random sampling of all persons involved in cleanup activities, stratified by type of worker and number of working days. Data were obtained via a structured questionnaire and included information on specific tasks, number of working days, use of protective materials, and acute health effects. These effects were classified into two broad groups: injuries and toxic effects. Data analysis was performed using complex survey methods. Significant differences between groups were evaluated using Pearson's chi(2) test. Unconditional logistic regression was used to compute odds ratios and 95% confidence intervals. Bird cleaners accounted for the highest prevalence of injuries (19% presented with lesions). Working more than 20 days in highly polluted areas was associated with increased risk of injury in all workers. Occurrence of toxic effects was higher among seamen, possibly due to higher exposure to fuel oil and its components. Toxic effects were more frequent among those working longer than 20 days in highly polluted areas, performing three or more different cleaning activities, having skin contact with fuel oil on head/neck or upper limbs, and eating while in contact with fuel or perceiving disturbing odors. No severe disorders were identified among individuals who performed these tasks. However, potential health impact should be considered when organizing cleanup activities in similar environmental disasters.

RESUMO

BACKGROUND: Population-based studies using a combination of molecular techniques and conventional epidemiological methods have been used to study the dynamics of tuberculosis (TB) transmission but the relative utility of each technique has not yet been established. METHODS: A prospective population-based molecular and epidemiological study of patients diagnosed with TB was conducted in three urban districts of Madrid (Spain) during 1997-1999. Analysis was performed using the capture-recapture method including covariates in which conventional epidemiological data and the information on clustered cases obtained by DNA fingerprinting were regarded as independent and complementary procedures. RESULTS: The estimate obtained by molecular analysis alone, that 31.6% of TB cases were due to recent transmission, was revised to 44.8% (95% CI: 31.4-58.2) using the capture-recapture method. The estimated completeness of the combined databases for identification of recent transmission was 59.2%. Underestimation of the true prevalence of recent transmission was higher with conventional epidemiology than molecular analysis, particularly for patients <35 years old and those with a history of imprisonment. CONCLUSIONS: In this study, use of the capture-recapture technique allowed us to combine epidemiological information obtained by conventional and molecular methods to quantify the number of cases of recently transmitted TB in the community and identify specific populations at high risk of disease. This information is clearly important because such groups are a prime target for improved TB control measures. In the long term, this combination of techniques may contribute significantly to control the spread of TB.

RESUMO

OBJECTIVE: To compare the diet of Spanish children against the nutrient and food intake guidelines. To calculate an index of overall diet quality and check its validity against nutrient intake. DESIGN AND SETTING: Cross-sectional study in four cities in Spain, where information on food and nutrient intake was obtained from schoolchildren through a food frequency questionnaire. PARTICIPANTS: The sample included 1112 children (overall response rate of 85%) attending public and private schools and aged 6-7 y. Children were selected through random cluster sampling in schools, and stratified by sex and socioeconomic level. MAIN OUTCOME MEASURES: Mean nutrient intake, number of food servings, and the percentage of children who meet recommended nutrient and food-serving intake levels. The overall dietary quality was assessed using the Healthy Eating Index (HEI). RESULTS: Mean micronutrient intake exceeded 100% of the recommended dietary allowances, except for vitamin B6, which registered a mean intake of 77.1%. For almost all children, intake of saturated fat was above, and that of carbohydrate below, the recommended level, in contrast to the relatively high compliance with the recommendations for poly- and monounsaturated fatty acid, salt and fiber intake (69.7, 43.7, 40.7, and 30.1%, respectively). Consumption of food servings for each of the five American pyramid food groups came close to or exceeded USDA guidelines, with the exception of cereals, with 5.4 servings per day. The mean score obtained in the HEI was 64.6. Children who complied with all the food guide pyramid recommendations registered a higher dietary variety and a healthier nutritional profile. CONCLUSIONS: Children aged 6-7 y show scant compliance with the macronutrient goals for healthy eating. Micronutrient intake is adequate in general, yet there are small groups of children with risk of deficient intake of vitamins B6 and D. While Spanish children's eating habits are reasonably in line with American food guide pyramid guidelines, consumptions of cereals and fruit should be improved.

RESUMO

Zn is an essential mineral. The role of Zn in atherosclerosis is not clear. Epidemiological studies, which have reported contradictory results, are limited by the use of serum Zn levels as a marker of intake. We assessed the association of toenail Zn, which integrates dietary Zn intake over 3 to 12 months, with the risk of a first myocardial infarction. Toenail Zn concentrations were determined by neutron activation analysis in the European multi-centre case-control study on antioxidants, myocardial infarction and breast cancer. This multi-centre case-control study included 684 cases and 724 controls from eight European countries and Israel. Toenail Zn levels of controls (adjusted for age and study centre) were positively associated with age, alpha-tocopherol and Se, but not with additional dietary variables or with classical risk factors for CHD. Average toenail Zn was 106.0 mg/kg in cases (95 % CI 103.1, 108.9) and 107.5 mg/kg in controls (95 % CI 104.5, 110.7). After controlling for cardiovascular risk factors and for centre, the adjusted odds ratios of myocardial infarction for quintiles 2-5 of toenail Zn with respect to the first quintile were 0.97 (95 % CI 0.59, 1.58), 1.15 (95 % CI 0.72, 1.85), 0.91 (95 % CI 0.56, 1.50), and 0.85 (95 % CI 0.52, 1.39). The P for trend was 0.45. In conclusion toenail Zn levels (reflecting long-term dietary intake) were not significantly associated with acute myocardial infarction.

RESUMO

The aim of the present study was to assess the principal food sources of energy and nutrients among Spanish children. We used a cross-sectional study design, based on results obtained from a food-frequency questionnaire. The sample included 1112 children, aged 6-7 years, from Cadiz, Madrid, Orense and Murcia, Spain. Children were selected through random cluster-sampling in schools. We analysed the percentage contributed by each food item to total energy and nutrient intake. The most important food sources were: white bread in the case of carbohydrate (13.4 %); olive oil in the case of total lipids (18.3 %) and monounsaturated fatty acids (29.2 %); whole milk in the case of protein (10.2 %) and saturated fatty acids (14.9 %); chips (French fried potatoes) in the case of polyunsaturated fatty acids (30.4 %). The greatest proportion of Na, consumed in excess, came from salt added to meals. Ham ranked second as a source of saturated fats. Fruits and green leafy vegetables proved to have great relevance as sources of fibre and vitamins, though with regard to the latter, it was observed that fortified foods (breakfast cereals, dairy products, fruit juices, etc.) had come to play a relevant role in many cases. In conclusion, the nutritional profile of Spanish school-aged children aged 6-7 years could be improved by nutritional policies targeted at limiting their consumption of ham (cured or cooked) and of salt added to meals, replacing whole milk with semi-skimmed milk, encouraging the consumption of products rich in complex carbohydrates already present in children's diets (bread, pasta, rice) and promoting less fatty ways of cooking food.

RESUMO

BACKGROUND AND AIM: Although dietary variety has been associated with a better nutritional profile, its possible role in obesity raises doubts about its overall health benefits. In this study, we examined the association between dietary variety and anthropometric variables, food intake and various food intake biomarkers in Spanish children. METHODS AND RESULTS: This was a cross-sectional study of 1112 children aged 6-7 years from Cadiz, Murcia, Orense and Madrid, who were selected by means of the random cluster-sampling of schools. Information concerning food and nutrient intake was obtained using a food frequency questionnaire, and a dietary variety index (DVI) was calculated on the basis of the number of different foods consumed more than once a month. The anthropometric variables (weight and height), and plasma lipid and vitamin levels were determined using standardised methods. Our results show that the body mass index (BMI) did not vary substantially as a function of DVI: it was 16.9 in the lowest DVI tertile and 17.2 in the highest (p=0.20). Unlike BMI, the DVI positively correlated (p<0.05) with the plasma levels of alpha and beta-carotene, lycopene, retinol, alpha-tocopherol and vitamin E, with energy intake, and with most of the foods, particularly vegetables, fruit and sausages (respective correlation coefficients of 0.43, 0.26 and 0.23). CONCLUSIONS: Dietary variety is associated with a better food and nutritional profile in Spanish children. Nevertheless, the presence of a positive association between the DVI and energy intake, and the consumption of sausages and pre-cooked products calls for the recommendation of a varied diet of healthy foods, such as cereals (especially whole grains), fruits and vegetables.
