Specific dyspeptic symptoms are associated with poor response to therapy in patients with gastroesophageal reflux disease.

INTRODUCTION: In patients with gastroesophageal reflux disease (GORD), co-existence of functional dyspepsia (FD) is known to be associated with poor response to proton pump inhibitors (PPIs), but the contribution of specific dyspepsia symptoms has not yet been systematically investigated. OBJECTIVE: We aimed to characterize the impact of dyspepsia symptoms on response to PPIs in patients with GORD. METHODS: The enrolled subjects were consecutive patients with a diagnosis of GORD. All patients underwent a 24 hour pH-impedance test, while on PPI therapy. Patients were divided into two groups, refractory and responders, according to the persistence of GORD symptoms. A standardized questionnaire for FD was also administered to assess presence of dyspepsia symptoms. RESULTS: In the subgroup of refractory patients FD was more prevalent than in responders, with post-prandial fullness, nausea, vomiting, early satiation and epigastric pain being significantly prevalent in refractory GORD patients. In the multivariate analysis only early satiation and vomiting were significantly associated with poor response to PPIs. CONCLUSION: Co-existence of FD is associated with refractory GORD. We showed that only early satiation and vomiting are risk factors for poor response to therapy with PPIs. Our findings suggest that symptoms of early satiation and vomiting would help to identify the subset of PPI-refractory GORD patients.

The Alternative Faces of Macrophage Generate Osteoclasts.

The understanding of how osteoclasts are generated and whether they can be altered by inflammatory stimuli is a topic of particular interest for osteoclastogenesis. It is known that the monocyte/macrophage lineage gives rise to osteoclasts (OCs) by the action of macrophage colony stimulating factor (M-CSF) and receptor activator of nuclear factor-kB ligand (RANKL), which induce cell differentiation through their receptors, c-fms and RANK, respectively. The multinucleated giant cells (MGCs) generated by the engagement of RANK/RANKL are typical OCs. Nevertheless, very few studies have addressed the question of which subset of macrophages generates OCs. Indeed, two main subsets of macrophages are postulated, the inflammatory or classically activated type (M1) and the anti-inflammatory or alternatively activated type (M2). It has been proposed that macrophages can be polarized in vitro towards a predominantly M1 or M2 phenotype with the addition of granulocyte macrophage- (GM-) CSF or M-CSF, respectively. Various inflammatory stimuli known to induce macrophage polarization, such as LPS or TNF-α, can alter the type of MGC obtained from RANKL-induced differentiation. This review aims to highlight the role of immune-related stimuli and factors in inducing macrophages towards the osteoclastogenesis choice.

miRNA profiling in serum and tissue samples to assess noninvasive biomarkers for NSCLC clinical outcome.

In NSCLC, the altered expression of some miRNAs in primary tumor tissues has been correlated with diagnosis and prognosis, while the role of circulating miRNAs as cancer biomarkers is currently emerging. MiRNA expression profile through miRNA Affymetrix array was evaluated on a training set formed by the tumor component (n = 30 NSCLC serum, n = 11/30 tumor tissues) and the control component (n = 10 healthy serum and n = 11/30 noncancerous counterparts). Statistical analyses highlighted the following: a = 55 miRNAs deregulated in tumor serum, b = 27 miRNAs deregulated in tumor tissues, and c = 2 miRNAs deregulated both in tumor serum and in tumor tissues. MiRwalk tool and enrichment pathway analyses selected some miRNAs whose target genes are correlated with the main pathways involved in NSCLC tumorigenesis. The altered expression of the selected miR-486-5p (a), miR-29c* (b), and miR-133a (c) was confirmed in the validation set (n = 40). MiR-486-5p had a higher expression in tumor serum than in tumor tissues (P = 0.004), and miR-29c* showed a lower expression in tumor tissues than in tumor serum (P < 0.001). MiR-133a had a not different expression in both tumor serum and tumor tissues (P = 0.07). The low level of miR-486-5p expression in the serum of affected patients was associated with a worse time to progression of disease (P = 0.010), and serum level of miR-486-5p was a significant prognostic indicator of NSCLC (adjusted hazard ratio = 0.179, P = 0.019). These data suggest the possibility to monitor affected patients through serum and/or tissue samples, analyzing the altered expression of specific miRNAs, in order to detect prognostic biomarkers in the NSCLC.

Decline of the Mediterranean diet at a time of economic crisis. Results from the Moli-sani study.

BACKGROUND AND AIMS: Adherence to Mediterranean diet (MD) is reportedly declining in the last decades. We aimed to investigate the adherence to MD over the period 2005-2010 and exploring the possible role of the global economic crisis in accounting for the changing in the dietary habits in Italy. METHODS AND RESULTS: Cross-sectional analysis in a population-based cohort study which randomly recruited 21,001 southern Italian citizens enrolled within the Moli-sani study. Food intake was determined by the Italian EPIC food frequency questionnaire. Adherence to MD was appraised by the Italian Mediterranean Index (IMI). A wealth score was derived to evaluate the economic position and used together with other socioeconomic indicators. Highest prevalence of adherence to MD was observed during the years 2005-2006 (31.3%) while the prevalence dramatically fell down in the years 2007-2010 (18.3%; P<0.0001). The decrease was stronger in the elderly, less affluent groups, and among those living in urban areas. Accordingly, we observed that in 2007-2010 socioeconomic indicators were strongly associated with higher adherence to MD, whereas no association was detected in the years before the economic crisis began; both wealth score and education were major determinants of high adherence to MD with 31% (95%CI: 18-46%) higher adherence to this pattern within the wealthier group compared to the less affluent category. CONCLUSION: Adherence to MD has considerably decreased over the last few years. In 2007-2010 socioeconomic indicators have become major determinants of adherence to MD, a fact likely linked to the economic downturn.

Biomineralization of Schlumbergerella floresiana, a significant carbonate-producing benthic foraminifer.

Most foraminifera that produce a shell are efficient biomineralizers. We analyzed the calcitic shell of the large tropical benthic foraminifer Schlumbergerella floresiana. We found a suite of macromolecules containing many charged and polar amino acids and glycine that are also abundant in biomineralization proteins of other phyla. As neither genomic nor transcriptomic data are available for foraminiferal biomineralization yet, de novo-generated sequences, obtained from organic matrices submitted to ms blast database search, led to the characterization of 156 peptides. Very few homologous proteins were matched in the proteomic database, implying that the peptides are derived from unknown proteins present in the foraminiferal organic matrices. The amino acid distribution of these peptides was queried against the uniprot database and the mollusk uniprot database for comparison. The mollusks compose a well-studied phylum that yield a large variety of biomineralization proteins. These results showed that proteins extracted from S. floresiana shells contained sequences enriched with glycine, alanine, and proline, making a set of residues that provided a signature unique to foraminifera. Three of the de novo peptides exhibited sequence similarities to peptides found in proteins such as pre-collagen-P and a group of P-type ATPases including a calcium-transporting ATPase. Surprisingly, the peptide that was most similar to the collagen-like protein was a glycine-rich peptide reported from the test and spine proteome of sea urchin. The molecules, identified by matrix-assisted laser desorption ionization-time of flight mass spectrometry analyses, included acid-soluble N-glycoproteins with its sugar moieties represented by high-mannose-type glycans and carbohydrates. Describing the nature of the proteins, and associated molecules in the skeletal structure of living foraminifera, can elucidate the biomineralization mechanisms of these major carbonate producers in marine ecosystems. As fossil foraminifera provide important paleoenvironmental and paleoclimatic information, a better understanding of biomineralization in these organisms will have far-reaching impacts.

Mushroom and dietary selenium intakes in relation to fasting glucose levels in a free-living Italian adult population: the Moli-sani Project.

AIM: Mushrooms are known to be a major food source of selenium, a mineral associated with diabetes prevalence. This study aimed to evaluate the relationship between mushroom and dietary selenium intakes and blood glucose levels in a free-living adult Italian population. METHODS: A total of 6879 men and 6891 women (aged 53.1±11.0years) with neither diabetes nor on special diets were analyzed from the population randomly recruited for the Moli-sani study. The European Prospective Investigation into Cancer and Nutrition (EPIC) food frequency questionnaire was used for dietary assessment. Fasting blood glucose (FBG) levels were measured from fasting serum samples, and diabetes prevalence was determined according to American Diabetes Association diagnostic criteria. RESULTS: In men, an increase of one (30-g) portion/week in mushroom consumption was associated with a 0.43-0.55mmol/L increase in FBG at different levels of adjustment (P<0.05). In both men and women, dietary selenium was positively associated with blood glucose in both unadjusted and fully adjusted models (P<0.05 for all). Both mushroom and dietary selenium intakes were independently associated with blood glucose on multivariate analyses. In addition, high intakes of both were associated with higher diabetes prevalence in men and women (OR>1, P<0.05). CONCLUSION: The association of mushroom and selenium intakes with FBG suggests that mushroom and selenium might each independently increase the risk of diabetes. However, prospective studies are now necessary to confirm this hypothesis.

Consumption of healthy foods at different content of antioxidant vitamins and phytochemicals and metabolic risk factors for cardiovascular disease in men and women of the Moli-sani study.

BACKGROUND/OBJECTIVES: To categorize healthy food groups into categories of low-antioxidant (LAC) or high-antioxidant vitamins and phytochemicals content (HAC) and comparatively associate them with metabolic risk factors for cardiovascular disease (CVD). SUBJECTS/METHODS: A total of 6879 women (55±12 years) and 6892 men (56 ± 12 years) were analyzed from the Moli-sani cohort, randomly recruited from the general population. The European Prospective Investigation into Cancer and Nutrition Food Frequency Questionnaire was used for dietary assessment. The antioxidant content of each food group was evaluated using Istituto Nazionale di Ricerca per gli Alimenti e la Nutrizione and United States Department of Agriculture (USDA) food composition tables. Healthy foods, according to a Mediterranean dietary pattern, were categorized into HAC or LAC; total food antioxidant content (FAC) score was constructed for a comparative evaluation of the consumption of these two groups. RESULTS: In men, an increase in FAC score, which represents an increased consumption of HAC with respect to LAC foods, was associated with a decrease in systolic blood pressure, diastolic blood pressure and C-reactive protein (CRP) (ß=-0.5, P=0.02, ß=-0.3, P=0.02 and ß=-0.03, P=0.03, respectively). Logistic regression analyses showed that in men 15% (30 units) increase in FAC score was associated with 6% decrease in the likelihood of having hypertension (odds ratio (OR)=0.94, 95% confidence interval (CI) 0.91-0.98) and 3% decrease in the likelihood of having a high CRP risk level (OR=0.97, 95% CI 0.94-0.99). No significant associations were observed in women. CONCLUSIONS: A possible greater protective role of healthy HAC as compared with healthy LAC foods on hypertension and inflammation was detected in men. These results stress the importance of studying healthy foods according to their content in antioxidant vitamins and phytochemicals, in primary prevention of CVD.

Typical breakfast food consumption and risk factors for cardiovascular disease in a large sample of Italian adults.

BACKGROUND AND AIMS: The overall consumption of foods most frequently consumed in a typical Italian breakfast might be associated with a better cardiovascular risk profile in Italian adults. METHOD SAND RESULTS: 18,177 subjects (53,2% women), aged ≥ 35 yrs, randomly selected from the Moli-sani Project population were studied. The European Prospective Investigation into Cancer and Nutrition (EPIC) FFQ was used for dietary assessment. To derive breakfast pattern, an "a priori" approach was used: firstly, foods typical of the Italian breakfast were selected: milk, coffee, tea, yogurt, crispbread/rusks, breakfast cereals, brioche, biscuits, honey, sugar and jam. The breakfast score was obtained adding the amounts of all selected foods, expressed in grams/day, previously standardized to mean zero and standard deviation 1. Subjects showing a higher breakfast score appeared to be younger, more frequently women or smokers, with higher social status but less likely practicing physical activity. After multivariable analyses, subjects with a higher breakfast food consumption had a lower risk to have high body mass index, abdominal obesity, systolic and diastolic blood pressure, blood glucose, triglycerides, total cholesterol (P < 0.0001 for all) and C Reactive Protein (P = 0.022). The associations were unrelated to age, sex, smoking, obesity, physical activity and social status. Subjects with a higher food breakfast score also showed a better physical healthy status score, a lower risk of metabolic syndrome (OR = 0.63; 0.55-0.72 95% CI) and of future CVD (P < 0.0001 for both women and men). CONCLUSION: Consumption of typical Italian breakfast foods positively affects CVD risk profile in an adult Italian population.

Total dietary antioxidant capacity and lung function in an Italian population: a favorable role in premenopausal/never smoker women.

BACKGROUND/OBJECTIVES: Antioxidant-rich foods may favorably influence lung function. We examined possible associations between the total dietary antioxidant capacity (TAC) and pulmonary function in a healthy Italian population. SUBJECTS/METHODS: Until May 2009, 22,300 persons were randomly recruited from the general population in the Moli-sani project. A sample only including healthy women (5824) and men (5848) was analyzed. TAC was measured in foods by three different assays and the ferric reducing-antioxidant power (FRAP) assay was selected as the better indicator of dietary TAC. The European Investigation into Cancer and Nutrition Food Frequency Questionnaire was used for dietary assessment. The association between quintiles of dietary FRAP and pulmonary indexes was assessed using analysis of variance separately for men and women. RESULTS: After adjustment for confounders, women in the highest quintile of FRAP intake had +39 ml forced expiratory volume in the first second (FEV(1)) and +54 ml forced vital capacity, compared with those in the lowest quintile (P for trend ≤0.006). Stratified analysis showed that this relationship only occurred in women who were premenopausal/never smokers. In this subgroup, the observed effect of higher FRAP intake on FEV(1) was equivalent to an improvement in pulmonary age of 3.3 years. In men, all significant associations between pulmonary function and TAC were lost after adjustment for confounding. CONCLUSIONS: Dietary TAC may have a favorable role in respiratory health, particularly in premenopausal/never smoker women.

Amphipols from A to Z.

Amphipols (APols) are short amphipathic polymers that can substitute for detergents to keep integral membrane proteins (MPs) water soluble. In this review, we discuss their structure and solution behavior; the way they associate with MPs; and the structure, dynamics, and solution properties of the resulting complexes. All MPs tested to date form water-soluble complexes with APols, and their biochemical stability is in general greatly improved compared with MPs in detergent solutions. The functionality and ligand-binding properties of APol-trapped MPs are reviewed, and the mechanisms by which APols stabilize MPs are discussed. Applications of APols include MP folding and cell-free synthesis, structural studies by NMR, electron microscopy and X-ray diffraction, APol-mediated immobilization of MPs onto solid supports, proteomics, delivery of MPs to preexisting membranes, and vaccine formulation.

Positive predictive value for malignancy on surgical excision of breast lesions of uncertain malignant potential (B3) diagnosed by stereotactic vacuum-assisted needle core biopsy (VANCB): a large multi-institutional study in Italy.

Percutaneous core biopsy (CB) has been introduced to increase the ability of accurately diagnosing breast malignancies without the need of resorting to surgery. Compared to conventional automated 14 gauge needle core biopsy (NCB), vacuum-assisted needle core biopsy (VANCB) allows obtaining larger specimens and has recognized advantages particularly when the radiological pattern is represented by microcalcifications. Regardless of technical improvements, a small percentage of percutaneous CBs performed to detect breast lesions are still classified, according to European and UK guidelines, in the borderline B3 category, including a group of heterogeneous lesions with uncertain malignant potential. We aimed to assess the prevalence and positive predictive values (PPV) on surgical excision (SE) of B3 category (overall and by sub-categories) in a large series of non-palpable breast lesions assessed through VANCB, also comparison with published data on CB. Overall, 26,165 consecutive stereotactic VANCB were identified in 22 Italian centres: 3107 (11.9%) were classified as B3, of which 1644 (54.2%) proceeded to SE to establish a definitive histological diagnosis of breast pathology. Due to a high proportion of microcalcifications as main radiological pattern, the overall PPV was 21.2% (range 10.6%-27.3% for different B3 subtypes), somewhat lower than the average value (24.5%) from published studies (range 9.9%-35.1%). Our study, to date the largest series of B3 with definitive histological assessment on SE, suggests that B3 lesions should be referred for SE even if VANCB is more accurate than NCB in the diagnostic process of non-palpable, sonographically invisible breast lesions.

SoC CMOS UWB Pulse Radar Sensor for Contactless Respiratory Rate Monitoring.

An ultra wideband (UWB) system-on-chip radar sensor for respiratory rate monitoring has been realized in 90 nm CMOS technology and characterized experimentally. The radar testchip has been applied to the contactless detection of the respiration activity of adult and baby. The field operational tests demonstrate that the UWB radar sensor detects the respiratory rate of person under test (adult and baby) associated with sub-centimeter chest movements, allowing the continuous-time non-invasive monitoring of hospital patients and other people at risk of obstructive apneas such as babies in cot beds, or other respiratory diseases.

ML segmentation strategies for object interference compensation in FDG-PET lesion quantification.

BACKGROUND: Quantification of lesion activity by FDG uptake in oncological PET is severely limited by partial volume effects. A maximum likelihood (ML) expectation maximization (EM) algorithm considering regional basis functions (AWOSEM-region) had been previously developed. Regional basis functions are iteratively segmented and quantified, thus identifying the volume and the activity of the lesion. OBJECTIVES: Improvement of AWOSEM-region when analyzing proximal interfering hot objects is addressed by proper segmentation initialization steps and models of spill-out and partial volume effects. Conditions relevant to lung PET-CT studies are considered: 1) lesion close to hot organ (e.g. chest wall, heart and mediastinum), 2) two close lesions. METHODS: CT image was considered for pre-segmenting hot anatomical structures, never for lesion identification, solely defined by iterations on PET data. Further resolution recovery beyond the smooth standard clinical image was necessary to start lesion segmentation. A watershed algorithm was used to separate two close lesions. A subtraction of the spill-out from a nearby hot organ was introduced to enhance a lesion for the initial segmentation and start the further quantification steps. Biograph scanner blurring was modeled from phantom data in order to implement the procedure for 3D clinical lung studies. RESULTS: In simulations, the procedure was able to separate structures as close as one pixel-size (2.25 mm). Robustness against the input segmentation errors defining the addressed objects was tested showing that convergence was not sensitive to initial volume overestimates up to 130%. Poor robustness was found against underestimates. A clinical study of a small lung lesion close to chest wall displayed a good recovery of both lesion activity and volume. CONCLUSIONS: With proper initialization and models of spill-out from hot organs, AWOSEM-region can be successfully applied to lung oncological studies.

Short- and long-term effects of a training session on pathologists' performance: the INQAT experience for histological grading in breast cancer.

Although the introduction of the Nottingham/Tenovus classification has improved the criteria to assess the histological grading in breast cancer, several quality control studies have shown that good results in terms of reproducibility are hard to obtain. This paper reports the results obtained during an implemented quality control programme for histological grading aimed at evaluating the short- and long-term effects of a training session on pathologists' performance. The interobserver reproducibility for grading score along with its components was assessed. The reproducibility between each pathologist and the reference values was also evaluated, as well as the contribution of each grading category to the observed reproducibility. Results show the weakness of a single training course in improving the long-term performance of the participating pathologists, suggesting the need to continuously monitor the quality of the grading determination by planning quality control studies and training sessions sequentially repeated in short time intervals.

Dietary patterns, cardiovascular risk factors and C-reactive protein in a healthy Italian population.

BACKGROUND AND AIMS: Dietary habits have been associated with cardiovascular disease (CVD) risk factors. This study aimed at evaluating the association of non-predefined dietary patterns with CVD risk profile and C-reactive protein (CRP). METHODS AND RESULTS: We analyzed 7646 healthy subjects from the Moli-sani project, an on-going cross-sectional cohort study of men and women aged >or=35, randomly recruited from a general Italian population. The Italian EPIC food frequency questionnaire was used. Food patterns were generated using principal factor analysis (PFA) and reduced rank regression (RRR). Three dietary patterns were identified by PFA. The "Olive Oil and Vegetables" pattern, characterized by high intake of olive oil, vegetables, legumes, soups, fruits and fish, was associated with relatively lower values of glucose, lipids, CRP, blood pressure and individual global CVD risk score. The "Pasta and Meat" pattern, characterized by high intake of pasta, tomato sauce, red meat, animal fats and alcohol, was positively associated with glucose, lipids, CRP and CVD risk score. The "Eggs and Sweets" pattern, characterized by positive loadings of eggs, processed meat, margarines, butter, sugar and sweets, was associated with high values of CRP. The first RRR pattern was similar to the "Pasta and Meat" pattern both in composition and association with CVD risk profile. CONCLUSIONS: In a large healthy Italian population, non-predefined dietary patterns including foods considered to be rather unhealthy, were associated with higher levels of cardiovascular risk factors, CRP and individual global CVD risk, whereas a "prudent-healthy" pattern was associated with lower levels.

BRCA1 expression and molecular alterations in familial breast cancer.

The aim of the study was to evaluate the performance of immunohistochemical MS110 expression in a series of familial and sporadic breast cancer patients. An immunohistochemical study was performed on TMA samples from 93 sporadic and 94 familial breast cancer patients with (7/94) and without BRCA1 germline mutations. BRCA1 protein expression level was evaluated using the monoclonal MS110 antibody. Immunohistochemistry, performed on TMA samples, showed positive nuclear staining for BRCA1 in 34 sporadic and 37 familial breast tumours, respectively. All the tumours from patients carrying BRCA1 mutations showed complete loss of both BRCA1 and ERalpha expression, regardless of the type of mutation. The percentage of MS110 positive cases was significantly lower in mutated versus wild type BRCA1 familial cases (p=0.02) while the percentage of patients with higher ERalpha expression was significantly lower in BRCA1-mutated versus BRCA1-wild type familial patients (p=0.05). Interestingly, the presence of the E1038G polymorphism in BRCA1 exon 11 was significantly associated with protein expression (p=0.029). The frequency of MS110 negative cases also detected in BRCA1-wild type tumours, points to the inability of the BRCA1 IHC expression in discriminating between familial and sporadic breast cancer.

Biology, prognosis and response to therapy of breast carcinomas according to HER2 score.

BACKGROUND: The standardization of the HER2 score and recent changes in therapeutic modalities points to the need for a reevaluation of the role of HER2 in recently diagnosed breast carcinoma. PATIENTS AND METHODS: A multicenter, retrospective study of 1794 primary breast carcinomas diagnosed in Italy in 2000/2001 and scored in HER2 four categories according to immunohistochemistry was conducted. RESULTS: Ductal histotype, vascular invasion, grade, MIB1 positivity, estrogen and progesterone receptor expression differed significantly in HER2 3+ tumors compared with the other categories. HER2 2+ tumors almost showed values intermediate between those of the negative and the 3+ subgroups. The characteristics of HER2 1+ tumors were found to be in between those of HER2 0 and 2+ tumors. With a median follow-up of 54 months, HER2 3+ status was associated with higher relapse rates in node-positive and node-negative subgroups, while HER2 2+ only in node positive. Analysis of relapses according to type of therapy provided evidence of responsiveness of HER2-positive tumors to chemotherapy, especially taxanes. CONCLUSIONS: The present prognostic significance of HER2 is correlated to receptor expression level and points to the need to consider HER2 2+ and HER2 3+ tumors as distinct diseases with different outcomes and specific features.

Wearable system-on-a-chip UWB radar for contact-less cardiopulmonary monitoring: present status.

The present status of the project aimed at the realization of an innovative wearable system-on-chip UWB radar for the cardiopulmonary monitoring is presented. The overall system consists of a wearable wireless interface including a fully integrated UWB radar for the detection of the heart beat and breath rates, and a IEEE 802.15.4 ZigBee low-power radio interface. The principle of operation of the UWB radar for the monitoring of the heart wall is summarized. With respect to the prior art, this paper reports the results of the experimental characterization of the intra-body channel loss, which has been carried out successfully in order to validate the theoretical model employed for the radar system analysis. Moreover, the main building blocks of the radar have been manufactured in 90 nm CMOS technology by ST-Microelectronics and the relevant performance are resulted in excellent agreement with those expected by post-layout simulations.

C reactive protein and its determinants in healthy men and women from European regions at different risk of coronary disease: the IMMIDIET Project.

AIM: Differences in C-reactive protein (CRP) levels and its determinants in three European populations at different risk of coronary artery disease (CAD) were studied. METHODS: Subjects were recruited randomly in Limburg (Belgium), Abruzzo (Italy) and south-west (SW) London (England). RESULTS: Ten-year risk of fatal coronary events (estimated using risk equations provided by the SCORE Project) was lower both in men and women from Abruzzo, intermediate in people from Limburg and higher in subjects from SW London. Within each country, high sensitivity (hs)-CRP levels were higher in the high-risk class in men but not in women. Men from Abruzzo had higher hs-CRP levels than those from Limburg and SW London. Women always had higher hs-CRP levels than men. The strongest hs-CRP determinant was body mass index (BMI, R(2) = 0.14) in women and waist circumference (WC, R(2) = 0.046) in men. The highest hs-CRP levels were observed in subjects with both high BMI and high WC. Metabolic syndrome was associated with high levels of CRP both in men and women, even after adjustment for confounders. DISCUSSION: Difference in CRP levels cannot explain the European gradient of CVD risk, although CRP levels are associated with the calculated SCORE risk of fatal coronary events within each country.
