RESUMEN

Current hypertension guidelines advocate strategies encouraging healthy lifestyle behaviours. So far, there is a paucity of studies for the efficacy of such multifaceted programmes. The aim of this study is to investigate the efficacy of an 8-week health-promotion programme for lowering blood pressure (BP) in prehypertensive and hypertensive patients in the community. This was a quasi-experimental study using wait-list controls of 548 patients. The intervention group was administered with an 8-week health-promotion intervention. Measurements included home BP, smoking, body mass index (BMI), perceived stress, depression, anxiety and Health Locus of Control. After adjusting for confounders, the intervention group had a significant reduction in both systolic BP (SBP; mean -2.62 mm Hg, 95% confidence interval (CI): -1.29 to -3.96) and diastolic BP (DBP; mean -1.0, 95% CI: -0.93 to -1.9) compared with controls. In all, 14.9% of patients in the intervention group had >10 mm Hg reduction in SBP vs 4.4% in the control group (P<0.001, numbers needed to treat (NNT)=10). With regards to DBP, 21.7% of patients in the intervention group had >5 mm Hg reduction vs 12.5% in the control group (P=0.01, NNT=11). In terms of effect size, moderate-to-large improvements of BMI, perceived stress, anxiety, depression, external and chance Health Locus of Control were recorded. Changes in SBP and DBP were attributed to BMI and depressive symptom reductions, respectively. Comprehensive non-pharmaceutical programmes for BP management are strongly encouraged. Their long-term benefits on cardiovascular morbidity and mortality remain to be established by future research.

RESUMEN

INTRODUCTION: Incomplete human extravillous trophoblast (EVT) invasion of the decidua and maternal spiral arteries is characteristic of pre-eclampsia, a condition linked to low maternal vitamin D status. It is hypothesized that dysregulated vitamin D action in uteroplacental tissues disrupts EVT invasion leading to malplacentation. METHODS: This study assessed the effects of the active vitamin D metabolite, 1,25-dihydroxyvitamin D3 (1,25-D3), and its precursor, 25-hydroxyvitamin D3 (25-D3), on primary human EVT isolated from first trimester pregnancies. Expression of EVT markers (cytokeratin-7, HLA-G), the vitamin D-activating enzyme (CYP27B1) and 1,25-D3 receptor (VDR) was assessed by immunocytochemistry. EVT responses following in vitro treatment with 1,25-D3 (0-10 nM) or 25-D3 (0-100 nM) for 48-60 h were assessed using quantitative RT-PCR (qRT-PCR) analysis of key target genes. Effects on EVT invasion through Matrigel(®) were quantified alongside zymographic analysis of secreted matrix metalloproteinases (MMPs). Effects on cell viability were assessed by measurement of MTT. RESULTS: EVT co-expressed mRNA and protein for CYP27B1 and VDR, and demonstrated induction of mRNA encoding vitamin D-responsive genes, 24-hydroxylase (CYP24A1) and cathelicidin following 1,25-D3 treatment. EVT could respond to 1,25-D3 and 25-D3, both of which significantly increased EVT invasion, with maximal effect at 1 nM 1,25-D3 (1.9-fold; p < 0.01) and 100 nM 25-D3 (2.2-fold; p < 0.05) respectively compared with untreated controls. This was accompanied by increased pro-MMP2 and pro-MMP9 secretion. The invasion was independent of cell viability, which remained unchanged. DISCUSSION: These data support a role for vitamin D in EVT invasion during human placentation and suggest that vitamin D-deficiency may contribute to impaired EVT invasion and pre-eclampsia.

RESUMEN

STUDY QUESTION: Does triiodothyronine (T3) regulate the secretion of angiogenic growth factors and cytokines by human decidual cells isolated from early pregnancy? SUMMARY ANSWER: T3 modulates the secretion of specific angiogenic growth factors and cytokines, with different regulatory patterns observed amongst various isolated subpopulations of human decidual cells and with a distinct change between the first and second trimesters of pregnancy. WHAT IS KNOWN ALREADY: Maternal thyroid dysfunction during early pregnancy is associated with complications of malplacentation including miscarriage and pre-eclampsia. T3 regulates the proliferation and apoptosis of fetal-derived trophoblasts, as well as promotes the invasive capability of extravillous trophoblasts (EVT). We hypothesize that T3 may also have a direct impact on human maternal-derived decidual cells, which are known to exert paracrine regulation upon trophoblast behaviour and vascular development at the uteroplacental interface. STUDY DESIGN, SIZE, DURATION: This laboratory-based study used human decidua from first (8-11 weeks; n = 18) and second (12-16 weeks; n = 12) trimester surgical terminations of apparently uncomplicated pregnancies. PARTICIPANTS/MATERIALS, SETTING, METHODS: Primary cultures of total decidual cells, and immunomagnetic bead-isolated populations of stromal-enriched (CD10+) and stromal-depleted (CD10-) cells, uterine natural killer cells (uNK cells; CD56+) and macrophages (CD14+) were assessed for thyroid hormone receptors and transporters by immunocytochemistry. Each cell population was treated with T3 (0, 1, 10, 100 nM) and assessments were made of cell viability (MTT assay) and angiogenic growth factor and cytokine secretion (immunomediated assay). The effect of decidual cell-conditioned media on EVT invasion through Matrigel(®) was evaluated. MAIN RESULTS AND THE ROLE OF CHANCE: Immunocytochemistry showed the expression of thyroid hormone transporters (MCT8, MCT10) and receptors (TRα1, TRß1) required for thyroid hormone-responsiveness in uNK cells and macrophages from the first trimester. The viability of total decidual cells and the different cell isolates were unaffected by T3 so changes in cell numbers could not account for any observed effects. In the first trimester, T3 decreased VEGF-A secretion by total decidual cells (P < 0.05) and increased angiopoietin-2 secretion by stromal-depleted cells (P < 0.05) but in the second trimester total decidual cells showed only increased angiogenin secretion (P < 0.05). In the first trimester, T3 reduced IL-10 secretion by total decidual cells (P < 0.05), and reduced granulocyte macrophage colony stimulating factor (P < 0.01), IL-8 (P < 0.05), IL-10 (P < 0.01), IL-1ß (P < 0.05) and monocyte chemotactic protein -1 (P < 0.001) secretion by macrophages, but increased tumour necrosis factor-α secretion by stromal-depleted cells (P < 0.05) and increased IL-6 by uNK cells (P < 0.05). In contrast, in the second trimester T3 increased IL-10 secretion by total decidual cells (P < 0.01) but did not affect cytokine secretion by uNK cells and macrophages. Conditioned media from first trimester T3-treated total decidual cells and macrophages did not alter EVT invasion compared with untreated controls. Thus, treatment of decidual cells with T3 resulted in changes in both angiogenic growth factor and cytokine secretion in a cell type-specific and gestational age-dependent manner, with first trimester decidual macrophages being the most responsive to T3 treatment, but these changes in decidual cell secretome did not affect EVT invasion in vitro. LIMITATIONS, REASONS FOR CAUTION: Our results are based on in vitro findings and we cannot be certain if a similar response occurs in human pregnancy in vivo. WIDER IMPLICATIONS OF THE FINDINGS: Optimal maternal thyroid hormone concentrations could play a critical role in maintaining a balanced inflammatory response in early pregnancy to prevent fetal immune rejection and promote normal placental development through the regulation of the secretion of critical cytokines and angiogenic growth factors by human decidual cells. Our data suggest that there is an ontogenically determined regulatory 'switch' in T3 responsiveness between the first and second trimesters, and support the notion that the timely and early correction of maternal thyroid dysfunction is critical in influencing pregnancy outcomes.

RESUMEN

The transplacental passage of thyroid hormones (THs) from mother to fetus in humans has been deduced from observational clinical studies and is important for normal fetoplacental development. To investigate the transporters that regulate TH uptake by syncytiotrophoblast (the primary barrier to maternal-fetal exchange, which lies in direct contact with maternal blood), we isolated the microvillous plasma membrane (MVM) of human term syncytiotrophoblasts. We have demonstrated that MVM vesicles express plasma membrane TH transporter proteins, including system-L (L-type amino acid transporter 1 and CD98), monocarboxylate transporters (MCTs) 8 and 10, organic anion-transporting polypeptides 1A2 and 4A1. We provide the first definitive evidence that the human syncytiotrophoblast MVM is capable of rapid, saturable T(4) and T(3) uptake at similar rates and in a Na(+)-independent manner. These two major forms of THs could not significantly inhibit each others' uptake, suggesting that each is mediated by largely different transporters. No single transporter was noted to play a dominant role in either T(4) or T(3) uptake. Using combinations of transporter inhibitors that had an additive effect on TH uptake, we provide evidence that 67% of saturable T(4) uptake is facilitated by system-L and MCT10 with a minor role played by organic anion-transporting polypeptides, whereas 87% of saturable T(3) uptake is mediated by MCT8 and MCT10. Our data demonstrate that syncytiotrophoblast may control the quantity and forms of THs taken up by the human placenta. Thus, syncytiotrophoblast could be critical in regulating transplacental TH supply from the mother to the fetus.

RESUMEN

BACKGROUND/OBJECTIVES: There are many different cultures within Europe, each with its own distinct dietary habits. Traditional foods are the key elements that differentiate the dietary patterns of each country. Unfortunately, in most countries, there is little information on the nutritional composition of such foods. Therefore, there is a need to study traditional foods to preserve these elements of European culture and, if possible, enrich and improve dietary habits across the continent. The Traditional Foods work package within the European Food Information Resource (EuroFIR) project aimed to provide new nutritional data on traditional foods for use in national food composition tables. SUBJECTS/METHODS: A EuroFIR consensus-based method with standardised procedures was applied for the systematic study of traditional foods and recipes in selected European countries. Traditional foods were selected on the basis of the EuroFIR definition of the term 'traditional food' and prioritized according to specific criteria. From the prioritized list, the five traditional foods per country to be investigated were selected to represent a full course meal. Protocols with guidelines for the recording of traditional recipes, the collection, preparation and distribution of laboratory samples, as well as quality requirements for laboratory selection, were developed to establish a common approach for use by all countries for the acquisition of reliable data. RESULTS: The traditional character of the selected foods has been documented and traditional recipes have been recorded. Chemical analyses to determine the nutritional composition of 55 traditional foods were performed and the data were evaluated and fully documented according to EuroFIR standards. Information on food description, the recipe, component identification, sampling plan, sample handling, analytical method and performance was collected for each of the 55 investigated traditional foods. CONCLUSIONS: This common methodology for the systematic study of traditional foods will enable countries to further investigate their traditional foods and to continue to update their national food composition databases and EuroFIR's food databank system.

RESUMEN

CONTEXT: Abnormal placentation in human pregnancy is associated with intrauterine fetal growth restriction (IUGR). Our group has previously reported the association between severe IUGR, lower fetal circulating concentrations of thyroid hormones (THs), and altered expression of TH receptors and TH transporters within human placental villi. We postulate that altered TH bioavailability to trophoblasts may contribute to the pathogenesis of IUGR. DESIGN AND OBJECTIVE: Cytotrophoblasts were isolated from normal and IUGR human placentae to compare their responsiveness to T(3) and their capability for T(3) transport. RESULTS: Compared with normal cytotrophoblasts, the viability of IUGR cytotrophoblasts (assessed by methyltetrazoleum assay) was significantly reduced (P < 0.001), whereas apoptosis (assessed using caspase 3/7 activity and M30 immunoreactivity) was significantly increased after T(3) treatment for 48 h (P < 0.001 and P < 0.01, respectively). The secretion of human chorionic gonadotropin was significantly increased by IUGR cytotrophoblasts compared with normal cytotrophoblasts (P < 0.001), independently of T(3) treatment. Net transport of [(125)I]T(3) was 20% higher by IUGR cytotrophoblasts compared with normal cytotrophoblasts (P < 0.001), and this was accompanied by a 2-fold increase in the protein expression of the TH transporter, monocarboxylate transporter 8, as assessed by Western immunoblotting (P < 0.01). CONCLUSIONS: IUGR cytotrophoblasts demonstrate altered responsiveness to T(3) with significant effects on cell survival and apoptosis compared with normal cytotrophoblasts. Increased monocarboxylate transporter 8 expression and intracellular T(3) accumulation may contribute to the altered T(3) responsiveness of IUGR cytotrophoblasts.

RESUMEN

Thyroid hormones (TH) are important for the development of the human fetus and placenta from very early gestation. The transplacental passage of TH from mother to fetus and the supply of TH into trophoblasts require the expression of placental TH plasma membrane transporters. We describe the ontogeny of the TH transporters MCT8, MCT10, LAT1, LAT2, OATP1A2 and OATP4A1 in a large series (n = 110) of normal human placentae across gestation and describe their expression changes with intrauterine fetal growth restriction (IUGR n = 22). Quantitative RT-PCR revealed that all the mRNAs encoding TH transporters are expressed in human placenta from 6 weeks gestation and throughout pregnancy. MCT8, MCT10, OATP1A2 and LAT1 mRNA expression increased with gestation. OATP4A1 and CD98 (LATs obligatory associated protein) mRNA expression reached a nadir in mid-gestation before increasing towards term. LAT2 mRNA expression did not alter throughout gestation. Immunohistochemistry localised MCT10 and OATP1A2 to villous cytotrophoblasts and syncytiotrophoblasts, and extravillous trophoblasts while OATP4A1 was preferentially expressed in the villous syncytiotrophoblasts. Whilst MCT8 protein expression was increased, MCT10 mRNA expression was decreased in placentae from IUGR pregnancies delivered in the early 3rd trimester compared to age matched appropriately grown for gestational age controls. No significant change was found in the mRNA expression of the other transporters with IUGR. In conclusion, several TH transporters are present in the human placenta from early 1st trimester with varying patterns of expression throughout gestation. Their coordinated effects may regulate both transplacental TH passage and TH supply to trophoblasts, which are critical for the normal development of the fetus and placenta. Increased MCT8 and decreased MCT10 expression within placentae of pregnancies complicated by IUGR may contribute to aberrant development of the fetoplacental unit.

RESUMEN

BACKGROUND/OBJECTIVES: Adequate mineral intake is important for the maintenance of bone health, cellular function and general metabolism, and possibly in the aetiology of cancer and other chronic diseases. This study aimed at investigating variation in intakes of selected minerals across 10 European countries participating in the EPIC (European Prospective Investigation into Cancer and Nutrition) study. METHODS: Nutrient intakes for 36 034 subjects, aged between 35 and 74 years, in 27 centres were obtained using standardized 24-h dietary recall software (EPIC-SOFT). Mean intakes of calcium, phosphorus, magnesium, iron and potassium were calculated by centre and weighted by season and day of the week and were also stratified by age group. The contribution of food groups to total nutrient intake was calculated. RESULTS: There was clear geographical variability in intakes, with differences ranging from 35% for magnesium to 90% for iron in men and 36% for potassium to 75% for calcium in women, and a twofold difference in sources of haem iron (meat and fish). There was a geographical gradient in iron intake, with higher intakes in Southern than in Northern Europe and also around a twofold north-south gradient in the contribution of fruits and vegetables to potassium intake. Compared with reference intakes, the majority of age groups and centres had intakes above the recommended levels. Dairy foods and products contributed the most to calcium and phosphorus intake in almost all centres. Cereals and cereal products contributed the most to magnesium and iron intakes, except in Greece and Germany. CONCLUSIONS: Intakes of minerals vary substantially throughout Europe, with some geographical variability in their food sources.

RESUMEN

OBJECTIVES: To describe the intake of the fat-soluble nutrients retinol, beta-carotene, vitamin E and vitamin D and their food sources among 27 redefined centres in 10 countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. METHODS: Between 1995 and 2000, 36,034 subjects (age range: 35-74 years) completed a single standardized 24-h dietary recall using a computerized interview software program (EPIC-SOFT). Intakes of the fat-soluble nutrients were estimated using the standardized EPIC Nutrient Database. RESULTS: For all the nutrients, in most centres, men had a higher level of intake than did women, even after adjustments for total energy intake and anthropometric confounders. Distinct regional gradients from northern to southern European countries were observed for all nutrients. The level intake of beta-carotene and vitamin E also showed some differences by level of education, smoking status and physical activity. No meaningful differences in the nutrient intake were observed by age range. CONCLUSIONS: These results show differences by study centre, gender, age and various lifestyle variables in the intake of retinol, beta-carotene, vitamin E and vitamin D between 10 European countries.

RESUMEN

OBJECTIVE: This paper describes the ad hoc methodological concepts and procedures developed to improve the comparability of Nutrient databases (NDBs) across the 10 European countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC). This was required because there is currently no European reference NDB available. DESIGN: A large network involving national compilers, nutritionists and experts on food chemistry and computer science was set up for the 'EPIC Nutrient DataBase' (ENDB) project. A total of 550-1500 foods derived from about 37,000 standardized EPIC 24-h dietary recalls (24-HDRS) were matched as closely as possible to foods available in the 10 national NDBs. The resulting national data sets (NDS) were then successively documented, standardized and evaluated according to common guidelines and using a DataBase Management System specifically designed for this project. The nutrient values of foods unavailable or not readily available in NDSs were approximated by recipe calculation, weighted averaging or adjustment for weight changes and vitamin/mineral losses, using common algorithms. RESULTS: The final ENDB contains about 550-1500 foods depending on the country and 26 common components. Each component value was documented and standardized for unit, mode of expression, definition and chemical method of analysis, as far as possible. Furthermore, the overall completeness of NDSs was improved (>or=99%), particularly for beta-carotene and vitamin E. CONCLUSION: The ENDB constitutes a first real attempt to improve the comparability of NDBs across European countries. This methodological work will provide a useful tool for nutritional research as well as end-user recommendations to improve NDBs in the future.

RESUMEN

OBJECTIVES: There is epidemiologic evidence that the consumption of fried, grilled or barbecued meat and fish that are well-done or browned may be associated with an increased cancer risk. These high-temperature cooking methods are thought to be surrogates for mutagens and carcinogens produced in meat and fish, eg heterocyclic amines or polycyclic hydrocarbons. Since data on food cooking methods are scarce, the aim of this study was to describe the variation in meat and fish cooking methods in different parts of Europe. DESIGN: Using a standardized 24 h recall from a sub-sample of the EPIC cohort (35 644 persons, 35-75 y old), mean daily intake of meat and fish prepared by different cooking methods and the relative contribution of the cooking methods to the overall cooking of meat and fish was calculated. RESULTS: Whereas frying was more often noted in northern Europe, roasting and stir frying were more often used in the south. Concerning high-temperature cooking methods, their frequency of application varies between 15% in the EPIC cohort of North-Italy and 49% in the cohort of The Netherlands. Average consumption of fried, grilled and barbecued meat and fish ranges from a low of 12 g/day in the centres in southern Spain to a high of 91 g/day in northern Spain. CONCLUSION: High variation in both the kind of meat/fish consumed as well as its cooking methods is observed within EPIC. In order to use this variation for the evaluation of the impact of cooking methods on cancer risk, a questionnaire on meat and fish cooking methods is being developed and could be applied in the whole EPIC cohort.

RESUMEN

OBJECTIVES: To describe and compare the consumption of dairy products in cohorts included in the European Prospective Investigation into Cancer and Nutrition (EPIC). METHODS: Data from single 24-hour dietary recall interviews collected through a highly standardised computer-based program (EPIC-SOFT) in 27 redefined centres in 10 European countries between 1995 and 2000. From a total random sample of 36 900, 22 924 women and 13 031 men were selected after exclusion of subjects under 35 and over 74 years of age. RESULTS: A high total consumption of dairy products was reported in most of the centres in Spain and in the UK cohort sampled from the general population, as well as in the Dutch, Swedish and Danish centres. A somewhat low consumption was reported in the Greek centre and in some of the Italian centres (Ragusa and Turin). In all centres and for both sexes, milk constituted the dairy sub-group with the largest proportion (in grams) of total dairy consumption, followed by yoghurt and other fermented milk products, and cheese. Still, there was a wide range in the contributions of the different dairy sub-groups between centres. The Spanish and Nordic centres generally reported a high consumption of milk, the Swedish and Dutch centres reported a high consumption of yoghurt and other fermented milk products, whereas the highest consumption of cheese was reported in the French centres. CONCLUSION: The results demonstrate both quantitative and qualitative disparities in dairy product consumption among the EPIC centres. This offers a sound starting point for analyses of associations between dairy intake and chronic diseases such as cancer.

RESUMEN

Various studies have demonstrated that the nutrient and non-nutrient substances present in vegetables and fruit (V&F) are most likely to be responsible for the beneficial effect of the increased V&F consumption. Urged by scientific evidence, current dietary guidelines strongly recommend the consumption of V&F in substantial amounts. In a recent paper (Brit. J. Nutr. 2000; 84, 549-556) V&F availability in 10 European countries was compared with the WHO recommendations (minimum combined V&F intake of about 400 g/day/person), as well as with guidelines of a minimum daily intake of three portions of vegetables (approx. 250 g/person) and two portions of fruit (approx. 150 g/person). All countries, excluding Greece, had a vegetable intake below the recommended minimum. Moreover, in all countries, the percentages of low vegetable consumers were significantly higher than those of low fruit consumers, suggesting that there is considerable room for improvement in the intake of vegetables, an important source of antioxidants. Wild edible greens are among the vegetables commonly consumed in Greece. These greens have a high flavonoid content, which in several cases substantially exceeds the respective values in foods and beverages, such as onions, black tea and red wine (Food Chemistry 2000; 70, 319-323). The high flavonoid content of edible wild greens requires consideration of their role in contemporary diet, as a possible mean for increasing vegetable consumption.

RESUMEN

Mortality statistics from the WHO database covering the period 1960 to 1990 have provided intriguing evidence that something unusual has been affecting in a beneficial way the health of the Mediterranean population. In recent papers, which evaluated the evidence accumulated over the last three decades, it was concluded that the traditional Mediterranean diet meets several important criteria for a healthy diet. Direct evidence in support of the beneficial properties of the Mediterranean diet has also become available. These data were derived from three studies, which have used a diet score, devised a priori on the basis of eight desirable key features of the traditional common diet in the Mediterranean region. The conclusion of these studies is that a diet that adheres to the principles of the traditional Mediterranean one is associated with longer survival. The Greek version of the Mediterranean diet is dominated by the consumption of olive oil and by high consumption of vegetables and fruits. Antioxidants represent a common element in these foods and an antioxidant action provides a plausible explanation for the apparent benefits. Wild edible greens frequently eaten in rural Greece in the form of salads and pies contain very high quantities of flavonoids-- considerably higher than those found in red wine or black tea. While there is no direct evidence that these antioxidants are central to the benefits of the Mediterranean Diet, indirect evidence from epidemiological data and the increasing understanding of their mechanisms of action suggest that antioxidants may play a major role.

RESUMEN

There is substantial evidence that several variants of the Mediterranean diet reduce the incidence of coronary heart disease (CHD) and perhaps other chronic conditions. Recently, the final results of the Lyon Diet Heart Study, a randomized secondary prevention trial, indicated that the Mediterranean diet substantially reduces the rate of recurrence after a first myocardial infarction. Data from this study also suggest that the Mediterranean diet protects against CHD through mechanisms that are independent of traditional CHD risk factors. We postulate that the antioxidant properties of several plant foods in the Mediterranean diet may be critical mediators of the beneficial effects of this diet.

RESUMEN

In a public psychotherapy clinic, the outcome of psychoanalytically oriented psychotherapy was investigated in a controlled study. The patients formed a treatment and a non-treatment (with initial evaluation) group, and psychotherapy was evaluated after 4 months of therapy. MMPI, target symptoms, global evaluation and other clinical evaluations were used. A number of aspects of the results are discussed pointing both to the efficacy of psychotherapy and the relative spontaneous improvement of the untreated patient.
