    Presentem els resultats del primer any de funcionament del Programa de Prevenció de la TBC del CAP de Ciutat Badia. Intentem trobar les fonts d'infecció estudiant no tan sols els contactes de malalts tuberculosos sinó també els contactes deis individus tuberculino-positius (infectats). La prevalença d'infecció tuberculosa en la població de 14-20 anys és de 12,54 % (8,88%-16,51%). S'han detectat 9 casos de tuberculosi activa que corresponen a un 3,67 % dels individus infectats trobats en l'estudi. Es discuteixen les diferencies d'infecció tuberculosa entre sexes, més gran en homes, de les quals no trobem cap referencia en la literatura. No podem afirmar que l'estudi de contactes d'infectats augmenti la rendibilitat del cribratge tuberculínic sistemàtic i haurem d'esperar avaluar un segon any per aconseguir mes precisió en les dades. Remarquem la importància del seguiment de la quimioprofilaxi tuberculosa amb un compliment del 75%, cosa que fa considerar que el control per infermeria educant i motivant la població pot ésser una mesura eficaç

    Resumen del trabajo presentado en el 20th International Congress of Nutrition, celebrado en Granada (España) del 15 al 20 de septiembre de 2013.[Background and objectives]: Vitamin K has been associated with a reduced risk of CHD and fatal cancer. Dietary menaquinones intake has been associated with cancer mortality. However, the association between the dietary intake of vitamin K and all-cause mortality has not been evaluated in a Mediterranean population at high cardiovascular risk.[Methods]: A prospective analysis was conducted in 7216 participants in the framework of the PREDIMED cohort (median follow-up: 4.8y). Energy and nutrient intakes were evaluated using a previously validated 137-item food frequency questionnaire. Dietary phylloquinone and menaquinone intake was calculated using the USDA database and previous published Abstracts Ann Nutr Metab 2013;63(suppl 1):1– 1960 921 data, respectively. All-cause mortality was verified by medical records and consultation of National Death Index. Cox proportional hazard models were fitted to assess the relative risk of all-cause mortality.[Results]: At baseline, energy-adjusted dietary phylloquinone intake was associated with a significantly reduced risk of all-cause mortality after controlling for potential confounders (HR: 0.64; 95% CI: 0.43, 0.96). No significant associations were found between quartiles of energy adjusted dietary menaquinones intake and risk of all-cause mortality. In a longitudinal manner, subjects who increase their consumption of vitamin K, phylloquinone or menaquinone, had a lower risk of allcause mortality (HR: 0.58; 95% CI: 0.45, 0.74 and HR: 0.59; 95% CI: 0.45, 0.78, respectively) compared with subjects who decrease their consumption.[Conclusions]: The results showed that an increase of dietary intake of vitamin K is related with a reduced risk of all-cause mortality in a Mediterranean population at high cardiovascular risk

    Background: The purpose of this study was to analyze the prevalence of nutrient intake inadequacy in Europe, applying the Nordic Nutritional Recommendations in the context of the EURRECA Network of Excellence. Methods: Nutrient data was obtained from the European Nutrition and Health Report II. Those nutritional surveys using a validated food frequency questionnaire or diet history and a food diary/register with at least 7 days of registers or with an adjustment for intraindividual variability were included. The nutrients analyzed were: vitamin C, vitamin D, vitamin B-12, folic acid, calcium, iron, zinc, selenium, copper, and iodine. The estimated average requirement cut point was applied to estimate inadequacy. The Nordic and Institute of Medicine nutrient recommendations were used as references. Results: The mean prevalence of inadequacy was below 11% for zinc, iron, and vitamin B-12 (only in the elderly), and it was 11-20% for copper in adults and the elderly and for vitamin B-12 in adults and vitamin C in the elderly. The prevalence was above 20% for vitamin D, folic acid, calcium, selenium, and iodine in adults and the elderly and for vitamin C in adults. Conclusions: Vitamin C, vitamin D, folic acid, calcium, selenium, and iodine were the nutrients showing a higher prevalence of inadequate intakes in Europe. Copyright (C) 2011 S. Karger AG, Base

    Background: A few observational studies have found an inverse association between adherence to a Mediterranean diet and the risk of depression. Randomized trials with an intervention based on this dietary pattern could provide the most definitive answer to the findings reported by observational studies. The aim of this study was to compare in a randomized trial the effects of two Mediterranean diets versus a low-fat diet on depression risk after at least 3 years of intervention. Methods: This was a multicenter, randomized, primary prevention field trial of cardiovascular disease (Prevención con Dieta Mediterránea (PREDIMED Study)) based on community-dwelling men aged 55 to 80 years and women aged 60 to 80 years at high risk of cardiovascular disease (51% of them had type 2 diabetes; DM2) attending primary care centers affiliated with 11 Spanish teaching hospitals. Primary analyses were performed on an intention-to-treat basis. Cox regression models were used to assess the relationship between the nutritional intervention groups and the incidence of depression. Results: We identified 224 new cases of depression during follow-up. There was an inverse association with depression for participants assigned to a Mediterranean diet supplemented with nuts (multivariate hazard ratio (HR) 0.78; 95% confidence interval (CI) 0.55 to 1.10) compared with participants assigned to the control group, although this was not significant. However, when the analysis was restricted to participants with DM2, the magnitude of the effect of the intervention with the Mediterranean diet supplemented with nuts did reach statistical significance (multivariate HR = 0.59; 95% CI 0.36 to 0.98). Conclusions: The result suggest that a Mediterranean diet supplemented with nuts could exert a beneficial effect on the risk of depression in patients with DM2

    Background: Alcoholic beverages are widely consumed. Depression, the most prevalent mental disorder worldwide, has been related to alcohol intake. We aimed to prospectively assess the association between alcohol intake and incident depression using repeated measurements of alcohol intake. Methods: We followed-up 5,505 high-risk men and women (55 to 80 y) of the PREDIMED Trial for up to seven years. Participants were initially free of depression or a history of depression, and did not have any history of alcohol-related problems. A 137-item validated food frequency questionnaire administered by a dietician was repeated annually to assess alcohol intake. Participants were classified as incident cases of depression when they reported a new clinical diagnosis of depression, and/or initiated the use of antidepressant drugs. Cox regression analyses were fitted over 23,655 person-years. Results: Moderate alcohol intake within the range of 5 to 15 g/day was significantly associated with lower risk of incident depression (hazard ratio (HR) and 95% confidence interval (95% CI) = 0.72 (0.53 to 0.98) versus abstainers). Specifically, wine consumption in the range of two to seven drinks/week was significantly associated with lower rates of depression (HR (95% CI) = 0.68 (0.47 to 0.98)). Conclusions: Moderate consumption of wine may reduce the incidence of depression, while heavy drinkers seem to be at higher risk

    Obesity Indexes and Total Mortality among Elderly Subjects at High Cardiovascular Risk: The PREDIMED Study

    Different indexes of regional adiposity have been proposed for identifying persons at higher risk of death. Studies specifically assessing these indexes in large cohorts are scarce. It would also be interesting to know whether a dietary intervention may counterbalance the adverse effects of adiposity on mortality. Methods: We assessed the association of four different anthropometric indexes (waist-to-height ratio (WHtR), waist circumference (WC), body mass index (BMI) and height) with all-cause mortality in 7447 participants at high cardiovascular risk from the PREDIMED trial. Forty three percent of them were men (55 to 80 years) and 57% were women (60 to 80 years). All of them were initially free of cardiovascular disease. The recruitment took place in 11 recruiting centers between 2003 and 2009. Results: After adjusting for age, sex, smoking, diabetes, hypertension, intervention group, family history of coronary heart disease, and leisure-time physical activity, WC and WHtR were found to be directly associated with a higher mortality after 4.8 years median follow-up. The multivariable-adjusted HRs for mortality of WHtR (cut-off points: 0.60, 0.65, 0.70) were 1.02 (0.78-1.34), 1.30 (0.97-1.75) and 1.55 (1.06-2.26). When we used WC (cut-off points: 100, 105 and 110 cm), the multivariable adjusted Hazard Ratios (HRs) for mortality were 1.18 (0.88-1.59), 1.02 (0.74-1.41) and 1.57 (1.19-2.08). In all analyses, BMI exhibited weaker associations with mortality than WC or WHtR. The direct association between WHtR and overall mortality was consistent within each of the three intervention arms of the trial. Conclusions: Our study adds further support to a stronger association of abdominal obesity than BMI with total mortality among elderly subjects at high risk of cardiovascular disease. We did not find evidence to support that the PREDIMED intervention was able to counterbalance the harmful effects of increased adiposity on total mortality

    Dietary intake and major food sources of polyphenols in a Spanish population at high cardiovascular risk: The PREDIMED study

    Get PDF
    [Background and aims]: Epidemiological data have shown an inverse association between the consumption of polyphenol-rich foods and the risk of cardiovascular disease or overall mortality. A comprehensive estimation of individual polyphenol intake in nutritional cohorts is needed to gain a better understanding of this association. The aim of this study was to estimate the quantitative intake of polyphenols and the major dietary sources in the PREDIMED (PREvención con DIeta MEDiterránea) cohort using individual food consumption records. [Methods and results]: The PREDIMED study is a large, parallel-group, multicentre, randomised, controlled 5-year feeding trial aimed at assessing the effects of the Mediterranean diet on the primary prevention of cardiovascular disease. A total of 7200 participants, aged 55–80 years, completed a validated 1-year food frequency questionnaire (FFQ) at baseline. Polyphenol consumption was calculated by matching food consumption data from the FFQ with the recently developed Phenol-Explorer database on polyphenol content in foods. The mean total polyphenol intake was 820 ± 323 mg day−1 (443 ± 218 mg day−1 of flavonoids and 304 ± 156 mg day−1 of phenolic acids). Hydroxycinnamic acids were the phenolic group with the highest consumption and 5-caffeoylquinic acid was the most abundantly ingested individual polyphenol. The consumption of olives and olive oil was a differentiating factor in the phenolic profile of this Spanish population compared with other countries. [Conclusion]: In Mediterranean countries, such as Spain, the main dietary source of polyphenols is coffee and fruits, but the most important differentiating factor with respect to other countries is the consumption of polyphenols from olives and olive oil.The authors would like to express their gratitude for financial support from CICYT (AGL2009-13906-C02-02 and AGL2010-22319-C03), RETICS-RD06/0045, and PI11/02505 from the Spanish Ministry of Economy and Competitiveness (MEC) and ACOMP/2012/190 from the Generalitat Valenciana.

    The dietary inflammatory index (DII) is a new tool to assess the inflammatory potential of the diet. In the present study, we aimed to determine the association between the DII and BMI, waist circumference and waist:height ratio (WHtR). We conducted a cross-sectional study of 7236 participants recruited into the PREvención con DIeta MEDiterránea trial. Information from a validated 137-item FFQ was used to calculate energy, food and nutrient intakes. A fourteen-item dietary screener was used to assess adherence to the Mediterranean diet (MeDiet). Sex-specific multivariable linear regression models were fitted to estimate differences (and 95 % CI) in BMI, waist circumference and WHtR across the quintiles of the DII. All nutrient intakes, healthy foods and adherence to the MeDiet were higher in the quintile with the lowest DII score (more anti-inflammatory values) except for intakes of animal protein, saturated fat and monounsaturated fat. Although an inverse association between the DII and total energy was apparent, the DII was associated with higher average BMI, waist circumference and WHtR after adjusting for known risk factors. The adjusted difference in the WHtR for women and men between the highest and lowest quintiles of the DII was 1·60 % (95 % CI 0·87, 2·33) and 1·04 % (95 % CI 0·35, 1·74), respectively. Pro-inflammatory scores remained associated with obesity after controlling for the effect that adherence to a MeDiet had on inflammation. In conclusion, the present study shows a direct association between the DII and indices of obesity, and supports the hypothesis that diet may have a role in the development of obesity through inflammatory modulation mechanisms
