- Abstract
Summary Background & aims Few prospective cohort studies have evaluated dietary iodine intake and urinary iodine concentrations in the general adult population. We assess the evolution of urinary iodine excretion and factors that may influence it in an adult population followed for 11 years. Methods A population-based cohort study was undertaken in Pizarra (Spain). In the three study phases (baseline ( n = 886), and 6 ( n = 788) and 11 years later ( n = 501)), participants underwent an interview and a standardized clinical examination that included a food questionnaire, and thyroid hormone and urinary iodine determinations. Subjects with thyroid dysfunction, palpable goiter or urinary iodine excretion >400 μg/L were excluded. Results Urinary iodine increased over the years (100.6 ± 70.0 μg/L at baseline vs. 125.4 ± 95.2 μg/L at 6 years and 141.6 ± 81.4 μg/L at 11 years; p < 0.0001). Urinary iodine was significantly higher in subjects who reported iodized salt consumption and in subjects with a higher intake of dairy products ( p < 0.05). Consumption of iodized salt (Risk ratio (RR) = 1.23, 95% CI [1.01–2.05]) and dairy products (RR = 2.07, 95% CI [1.01–4.23]), and a baseline urinary iodine concentration ≥100 μg/L (RR = 1.26, 95% CI [1.04–1.53]) were significantly associated with urinary iodine concentrations ≥100 μg/L at 11 years. There is no correlation between thyroid function (TSH, free triiodothyronine or free thyroxine levels) and urinary iodine concentrations in conditions of iodine sufficiency. Conclusions The increase in urinary iodine concentrations over eleven years is associated with an increase in iodized salt intake and with the dairy products intake, and possibly with a higher iodine content of dairy products. However, individual variability in urinary iodine excretion was not fully explained by dietary iodine intake alone; previous urinary iodine concentrations were also important. [ABSTRACT FROM AUTHOR]

- Abstract
Background and Aim: Prevalence rates of "metabolically healthy obese" (MHO) subjects vary depending on the criteria used. This study examined the prevalence and characteristics of MHO subjects and metabolically abnormal normal-weight subjects and compared the findings with the NHANES 1999-2004 study. The aims of the present study were, first, to determine the prevalence rates of MHO and MNHNO subjects using the same criteria as those of the National Health and Nutrition Examination Survey (NHANES) (1999-2004) study, and second to compare the prevalence and correlates of obese subjects who are resistant to the development of adiposity-associated cardiometabolic abnormalities (CA) and normal-weight individuals who display cardiometabolic risk factor clustering between the Spanish and the US populations.Methods and Results: Di@bet.es study is a national, cross-sectional population-based survey of 5728 adults conducted in 2009-2010. Clinical, metabolic, sociodemographic, and anthropometric data and information about lifestyle habits, such as physical activity, smoking habit, alcohol intake and food consumption, were collected. Subjects were classified according to their body mass index (BMI) (normal-weight, <25 kg/m(2); overweight, 25-29.9 kg/m(2); and obese, >30 kg/m(2)). CA included elevated blood pressure; elevated levels of triglycerides, fasting glucose, and high-sensitivity C-reactive protein (hs-CRP); and elevated homeostasis model assessment of insulin resistance (HOMA-IR) value and low high-density lipoprotein cholesterol (HDL-c) level. Two phenotypes were defined: metabolically healthy phenotype (0-1 CA) and metabolically abnormal phenotype (≥2 CA). The prevalence of metabolically abnormal normal-weight phenotype was slightly lower in the Spanish population (6.5% vs. 8.1%). The prevalence of metabolically healthy overweight and MHO subjects was 20.9% and 7.0%, respectively, while in NHANES study it was 17.9% and 9.7%, respectively. Cigarette smoking was associated with CA in each phenotype, while moderate physical activity and moderate alcohol intake were associated with being metabolically healthy. Olive oil intake was negatively associated with the prevalence of CA.Conclusions: Smoking, physical activity level, and alcohol intake contribute to the explanation of the prevalence of CA in the Spanish population, as in the US population. However in Spain, olive oil intake contributes significantly to the explanation of the variance in the prevalence of CA. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Summary: Background & aim: Recent studies suggest that white rice consumption increases risk of diabetes. Aim: to assess the association between white rice intake and the incidence of diabetes in a population from Southern Spain. Methods: A population-based cohort study was undertaken in Pizarra, Spain. At baseline and follow-up, participants underwent an interview and a standardized clinical examination which included an oral glucose tolerance test in those subjects without known diabetes. Incidence and odds ratio (OR) for diabetes were calculated. Multivariate analysis was performed using stepwise logistical regression. Results: Thirty eight percent of subjects reported rice consumption 2–3 times a week, 58.5% once or less a week, and 3.6% no rice consumption. In subjects who reported rice intake 2–3 times a week, incidence of diabetes after 6 years follow-up was 12.0%, and in those who reported once or less a week, 20.2% (p = 0.04, non adjusted). Subjects who ate rice frequently had lower risk to develop diabetes 6 years later (OR = 0.43, p = 0.04; adjusted for age, sex, obesity, and presence of impaired fasting glucose and/or impaired glucose tolerance at baseline). Conclusions: A negative association was found between white rice intake in the way it is consumed in Southern Spain, and the 6 years incidence of diabetes. [Copyright &y& Elsevier]

Abstract: The Spanish paradox is a phenomenon observed in Spain and some other Mediterranean countries by which the cardiovascular morbidity and mortality levels are dissociated from their cardiovascular risk factors. The Mediterranean diet has been proposed as the main reason for this dissociation, but dietary changes themselves are not enough to explain this situation. It has been recently discovered that Stearoil-CoA desaturase (SCD) is involved in the dissociation between a favourable atherogenic metabolic profile and the risk for arteriosclerosis. We propose a hypothesis that attempts to clarify the Spanish paradox. This hypothesis contemplates the essential role of dietary olive oil and its interaction with different SCD genetic patterns. Confirmation of this hypothesis could provide the basis for the design of clinical and preventive strategies against cardiovascular morbidity and mortality, as well as certain metabolic risk factors.

- Abstract
Summary: Background & aims: Oxidative stress is believed to play an important role in the pathophysiology of bronchiectasis. The aims of this study were to evaluate the oxidative stress status in bronchiectasis patients. Methods: This cross-sectional study included 90 clinically stable adults with bronchiectasis of any aetiology (36 with cystic fibrosis [CF] and 54 without CF) plus 50 healthy controls. Plasma and serum oxidative stress biomarkers were measured using commercial kits. Cellular oxidative stress biomarkers in white blood cells (mitochondrial membrane potential, intracellular glutathione, superoxide anion and hydrogen peroxide) were analyzed by flow cytometry. Results: Compared with the control group, the catalase activity and lipid peroxidation (TBARs and 8-isoprostanes) were significantly increased in the patient group and the total antioxidant capacity and the activity of superoxide dismutase were decreased. Intracellular superoxide anion and hydrogen peroxide were significantly elevated in the patients versus the controls in total leukocytes, lymphocytes, monocytes and neutrophils. Compared to the controls, the mitochondrial membrane potential was significantly lower in neutrophils and intracellular glutathione in monocytes. No significant differences were observed between CF and non-CF bronchiectasis patients in the oxidative stress biomarkers studied. Conclusions: Biomarkers of oxidative stress, both in plasma and intracellular were raised in patients with bronchiectasis compared with controls. No differences were seen in the CF patients compared with the others. [Copyright &y& Elsevier]

- Abstract
Summary: Background & aims: The importance of milk intake to the supply of dietary iodine is not fully known. We therefore undertook a study in Spain of the iodine concentration in cow’s milk and the impact of the frequency of milk consumption on urinary iodine concentrations in three study populations. Methods: We studied the iodine concentration in 362 samples of milk from 45 commercial brands and compared it with the milk iodine status in studies undertaken 17 years earlier. The epidemiologic studies were performed in three different places in the south of Spain: two in school-age children (N = 757 and N = 1205 children) and one in adults (N = 1051). A milk consumption questionnaire was given and urinary iodine concentrations measured. Results: The mean concentration of iodine in the milk rose from 1991 (117 ± 37 μg/L) to 2008 (259 ± 58 μg/L) (P < 0.001). The iodine concentration was greater in skimmed milk (273 ± 52 μg/L) than in semi-skimmed milk (254 ± 57 μg/L) or whole milk (251 ± 61 μg/L) (P < 0.0001). The winter samples had a greater concentration of iodine (270 ± 55 μg/L) than the summer samples (247 ± 58 μg/L) (P < 0.0001), independently of the type of milk. The urinary iodine concentrations in all three epidemiologic studies were significantly associated with the frequency of milk intake. Conclusions: The concentration of iodine in cow’s milk has risen over recent years, and it is higher in skimmed milk. The results also show that cow’s milk is a relevant source of dietary iodine.

- Abstract
Summary: Background & aims: To analyse the trends in consumption and costs of home enteral nutrition (HEN) products in Andalusia (Spain) and estimate the prevalence of HEN from 2000 to 2007. Methods: Using the defined daily dose (DDD) method, we assigned a DDD to each type of diet, grouped as whole diets, supplements, modules and thickeners. The number of cases/10
6 inhabitants/day (CID) was calculated. Results: The number of persons receiving HEN rose notably, from 66.4 CID in 2000 to 1315.4 in 2007. The number of persons with home enteral tube feeding has remained stable since 2003, at around 220 CID. HEN with oral nutritional supplements (ONS) increased exponentially, with a prevalence of 910 CID in 2007. The prevalence of HEN in 2007 was similar to that of other European countries. The costs associated with HEN rose from 1.3 million euros in 2000 to over 37 million euros in 2007, due to the progressive increase in the number of persons being prescribed HEN, especially ONS, and the incorporation of more expensive organ-specific formulas. Conclusions: DDD is useful to indirectly estimate the prevalence of HEN and evaluate long-term trends in the prescription and costs of various HEN products. [Copyright &y& Elsevier]- Published

Abstract: Although various studies have noted fatty-acid-mediated regulation of adipocyte lipolysis, determining the isolated effect of a single fatty acid is more difficult. We examined the influence of dietary oleic acid on adipose cell lipolytic activity and the tissue fat content independently of the variation in other dietary fatty acids. We fed 48 rats with six diets designed so that the oleic acid content was not correlated with the content of any other fatty acid and studied the lipolytic activity and fatty acid content of the tissues. There were no differences in the weight of the animals after the diet. The muscle fat content and the epinephrine-stimulated lipolytic activity varied significantly according to the dietary levels of oleic acid and the tissues, showing a dose-dependent behavior of the dietary oleic acid concentration. The results of this study show that diets rich in oleic acid have a beneficial effect on the regulation of lipid metabolism and body weight homeostasis. [Copyright &y& Elsevier]

Activation of the PPAR gamma 2 gene (PPARG2) improves the action of insulin and its lipid metabolism. We examined the association between Pro12Ala polymorphism of PPARG2, type 2 diabetes mellitus (DM2), and peripheral insulin sensitivity in a population with a high intake of oleic acid. A cross-sectional, population-based study was undertaken in Pizarra, a small town in the province of Malaga in southern Spain. A total of 538 subjects, aged 18-65 y, were selected randomly from the municipal census. All subjects underwent a clinical, anthropometrical, and biochemical evaluation, including an oral glucose tolerance test and Pro12Ala polymorphism of PPARG2. Insulin resistance was measured by homeostasis model assessment. Those subjects with the Ala-12 allele had an odds ratio for impaired fasting glucose of 0.55, for impaired glucose tolerance of 0.59, and for DM2 of 0.30. The intake of monounsaturated fatty acids (MUFA) contributed to the variance of the homeostasis model assessment insulin resistance index (HOMA IR) (P = 0.04), with a 2-way interaction between the Ala-12 allele of PPARG2 and the intake of MUFA (P = 0.005). The results suggest the existence of an interaction between Pro12Ala polymorphism of PPARG2 and dietary MUFA, such that obese people with the Ala-12 allele have higher HOMA IR values, especially if their intake of MUFA is low.

- Abstract
Summary: Background & aims: Patients with metabolic syndrome (MS) have increased cardiovascular risk factors. Dietary modifications mainly polyunsatturated fatty acids intake, can improve them. The present study was performed to assess the effects of enriched milk with ω-3 and oleic fatty acids, folic acid and vitamin E, in these patients. Methods: We performed a randomized, placebo-controlled and open clinical trial, among 72 patients with MS for 3 months. Thirty-six of them consumed 500cm
3 per day of semi-skimmed milk (control group), and the others consumed 500cm3 per day of enriched milk (test group). Daily supplements in this group were 5.7g of oleic acid, 0.2g of ω-3 fatty acid, 150μg of folic acid and 7.5mg of vitamin E. Serum for total and HDL cholesterol, triglycerol, Apo B, glucose, insulin, hs-CRP, homocysteine and fatty acids contents in serum phospholipids, was obtained at the beginning and at the end of the study. LDL cholesterol was calculated by Friedewald formula. Results: Four patients in the test group, and two in the control group dropped out. In the test group a decrease in serum total cholesterol (−6.2%, ), LDL cholesterol (−7.5%, ), triglycerol (−13.3%, ), Apo B (−5.7%, ), glucose (−5.3%, ), and homocysteine (−9.5%, ) was observed. Any of these parameters changed in the control group. Conclusions: Dietary supplementation with 500cm3 of enriched milk with ω-3 fatty acid, oleic acid and folic acid, reduces serum tryglicerides, total and LDL cholesterol, Apo B, glucose and homocysteine in patients with MS. This milk is well tolerated and accepted by the patients. [Copyright &y& Elsevier]- Published

- Abstract
Background: The family kitchen resembles an uncontrolled laboratory experiment, and some discrepancies in the relation between the risk of hypertension and dietary fat may be partly due to the manipulation to which the fats were subjected. Objective: We investigated whether deterioration in the quality of the cooking oils in the family household contributes to the risk of high blood pressure. Design: The study was cross-sectional. Anthropometric measurements were obtained for 1226 persons aged 18-65 y who were selected randomly from the municipal census of Pizarra, Spain. An oral-glucose-tolerance test was given to 1020 of these persons. Samples of the cooking oil being used were taken from the kitchens of a random subset of 538 persons. The concentrations of polar compounds and polymers were used as markers of the deterioration of the oils. The strength of association between variables was measured by calculating the odds ratio from logistic models. Results: Hypertension was strongly associated with obesity and was influenced by sex, diabetes, and age. The presence of excess polar compounds in the cooking oil and the use of sunflower oil were related to the risk of hypertension, whereas the concentration of monounsaturated fatty acids in the serum phospholipids was negatively related to this risk. These associations remained after inclusion in the models of age, sex, obesity, and the presence of carbohydrate metabolism disorder. Conclusions: The risk of hypertension is positively and independently associated with the intake of cooking oil polar compounds and inversely related to blood concentrations of monounsaturated fatty acids.

- Abstract
Summary: Background & aims: To investigate the relationship between levels of 25-hydroxyvitamin D and the incidence of type 2 diabetes in a Spanish population. Methods: We undertook a population-based prospective study in a population from southern Spain. The first phase of the study (1996–1998) included 1226 individuals. Of this original cohort, 988 persons were reassessed in 2002–2004 and 961 in 2005–2007. Measurements were made of 25-hydroxyvitamin D and intact parathyroid hormone in 2002–2004 and an oral glucose tolerance test was done in three time points. Results: The incidence of diabetes in subjects with 25-hydroxyvitamin D levels ≤18.5 ng/mL (percentile 25) was 12.4% vs 4.7% in subjects with levels >18.5 ng/mL. The likelihood of having diabetes during the four years of follow-up was significantly lower in the subjects with higher levels of 25-hydroxyvitamin D [OR = 0.17 (0.05–0.61)]. None of the subjects with levels higher than 30 ng/mL developed diabetes. Conclusion: In this prospective study, we found a significant inverse association between serum 25-hydroxyvitamin D levels and the risk for type 2 diabetes in a population from the south of Spain.

The factors regulating TNF alpha (TNFa) levels could be considered therapeutic targets against metabolic syndrome development. DNA methylation is a potent regulator of gene expression and may be associated with protein levels. In this study we investigate whether the effect of dietary fatty acids on TNFa released from adipocytes might be associated with modifications of the TNFa promoter DNA methylation status. A group of rats was assigned to three diets with a different composition of saturated, monounsaturated and polyunsaturated fatty acids. Samples of visceral adipose tissues were taken for adipocyte isolation, in which released TNFa levels were measured, and for methylation and expression studies. In addition, 3 T3-L1 cells were treated with palmitic, oleic and linoleic acids, with and without 5-Azacitydine (5-AZA). After treatments, cells and supernatants were included in the same analyses as rat samples. TNFa promoter methylation levels, gene expression and secretion were different according to the diets and fatty acid treatments associated with them. Cells treated with 5-AZA displayed higher TNFa levels than in the absence of 5-AZA, without differences between fatty acids. According to our results, dietary fatty acid regulation of adipocyte TNFa levels may be mediated by epigenetic modifications of the TNFa promoter DNA methylation levels. [ABSTRACT FROM AUTHOR]

Fat-free mass depletion has been related to increased inflammatory activity and to increased morbidity and mortality in chronic respiratory diseases. The aims of our study were to determine the nutritional status and serum levels of adipocytokines and inflammatory cytokines in patients with bronchiectasis of any etiology and their relation with respiratory parameters. A cross-sectional study was designed that included patients aged >14 years with diagnostic criteria for bronchiectasis. Anthropometric parameters; a diet questionnaire; hand grip dynamometry; levels of leptin, adiponectin, interleukin-6 (IL-6), tumor necrosis factor-α, and ultrasensitive C-reactive protein; as well as respiratory parameters (ie, clinical, radiologic, and spirometric values) were assessed. Ninety-three clinically stable patients were recruited, 43 with cystic fibrosis, 31 with noncystic fibrosis bronchiectasis, and 19 with cystic fibrosis transmembrane conductance regulator-related bronchiectasis. Fat-free mass depletion was present in 31% of patients, with no differences according to the etiology of the bronchiectasis. Correlations were found between inflammatory cytokines (ie, IL-6) and exacerbations, bronchorrea, forced expiratory volume in 1 second, and Bhalla score. Patients with worse respiratory disease severity, malnutrition, and diabetes had significantly higher levels of IL-6. Adiponectin correlated significantly and positively with fat mass and fat mass index and negatively with fat-free mass, fat-free mass index, and hand dynamometry. Leptin correlated positively with body mass index, fat mass and fat mass index, and negatively with fat-free mass, fat-free mass index, and dynamometry. Patients with bronchiectasis present a high percentage of fat-free mass depletion, independent of the etiology of the disease. The levels of inflammatory cytokines (especially IL-6) may be useful markers of disease severity. Adiponectin levels were higher in patients with fat-free mass depletion. [Copyright &y& Elsevier]

Abstract: The aim of this prospective, adult population-based study was to analyse the prevalence of type 2 diabetes mellitus in relation to the intake of cows’ milk and the prevalence of anti-beta-lactoglobulin (anti-β-LG) antibodies. Measurements were made of weight, height, levels of anti-islet antibodies, anti-β-LG antibodies and tumour necrosis factor alpha (TNF-α) in all the participants. The likelihood of having positive anti-β-LG antibodies was higher in subjects who consumed milk more frequently. Subjects who consumed milk less than once per day were more likely to have type 2 diabetes than those who consumed milk more than once per day. The levels of TNF-α were significantly higher in individuals with positive anti-β-LG antibodies and in those who consumed milk more often. The prevalence of anti-β-LG antibodies was associated with the intake of milk and with the TNF-α levels, but not with the prevalence of type 2 diabetes. [Copyright &y& Elsevier]

Abstract: Aims: We studied the changes in the incidence of lower limb amputation (LLA) in Andalusia from 1998 to 2006 in the population with and without diabetes. Methods: We undertook a retrospective study of all LLA performed in Andalusia in people aged 30 years old, with or without diabetes, between 1 January 1998 and 31 December 2006. We obtained the crude and standardized incidence rates by year, and sex for three periods: 1998–2000, 2001–2003 and 2004–2006 and calculated the RR of requiring LLA in patients with diabetes. To test for time trend, Poisson regression models were fitted. Results: A total of 16,210 LLA were carried out in Andalusia, 72.6% in patients with diabetes mellitus and 66.4% in men. In the population with diabetes the standardized incidence of all LLA was found to be 344.0 per 100,000 (95% CI, 315.4–372.4) in 2004–2006. There was an estimated incidence increase for all LLA by 14% and for minor LLA by 13.6% in 2004–2006. In people with diabetes the RR increased by 31.6% as compared to the first period. Conclusions: Despite the implementation of a care plan for patients with diabetes, the incidence of LLA has not fallen in Andalusia in recent years. [Copyright &y& Elsevier]

Abstract: Objective: To identify different markers in order to validate the assessment of dietary intake in adults with cystic fibrosis (CF). Design: Cross-sectional survey. Setting: Tertiary care. Subjects: We assessed 37 adults with CF whose nutritional and respiratory condition was stable and 37 healthy adults, matched for age, sex, and nutritional status. Interventions: A consecutive, 7-day, prospective dietary survey was given to all the participants. Anthropometric variables were measured and a fasting blood sample was drawn to measure the composition of the serum phospholipid fatty acids by gas chromatography. We also measured fecal fat and nitrogen at 72 hours and 24-hour urine nitrogen. Results: The ratio of energy intake to basal metabolic rate expenditure was significantly greater in the patients (2.1±0.4) than the controls (1.79±0.4) and the percentage of patients with the ratio of energy intake to basal metabolic rate lower than 1.55 was 24% in the controls (n=9) vs 8% in the patients (n=3). Fecal nitrogen correlated significantly with total energy and the intake of carbohydrates, lipids, and proteins. In the patients, total dietary energy and fat and protein intake correlated positively with fecal fat. The protein and fat intake and fecal nitrogen and fat correlated significantly with urine nitrogen. In the controls, significant correlations were seen between different parameters of intake and the percentage of certain serum phospholipid fatty acids. These correlations in the patients were either absent or less marked. Conclusions: Use in persons with CF of the energy intake to basal metabolic rate ratio, measurement of fecal fat and nitrogen at 72 hours and of urine nitrogen may be useful to validate dietary surveys. The serum phospholipid fatty acid profile, however, may be less useful for this purpose in these patients. [Copyright &y& Elsevier]
