Abstract
BACKGROUND Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited cerebral microangiopathy presenting with variable features, including migraine, psychiatric disorders, stroke, and cognitive decline and variable disability. On neuroimaging, CADASIL is characterized by leukoencephalopathy, multiple lacunar infarcts, and microbleeds. Previous studies suggest a possible role of endothelial impairment in the pathogenesis of the disease. METHODS We assessed plasma levels of von Willebrand factor (vWF) and thrombomodulin (TM) and the blood levels of endothelial progenitor cells (EPCs) and circulating progenitor cells (CPCs) in 49 CADASIL patients and 49 age-matched controls and their association with clinical/functional and neuroimaging features. RESULTS In multivariate analysis, CADASIL patients had significantly higher vWF and lower EPC levels. TM levels were similar in the 2 groups. CADASIL patients with a more severe clinical phenotype (history of stroke or dementia) presented lower CPC levels in comparison with patients with a milder phenotype. On correlation analysis, lower CPC levels were associated with worse performances on neuropsychological, motor and functional tests, and with higher lesion load on brain magnetic resonance imaging (degree of leukoencephalopathy and number of lacunar infarcts). CONCLUSIONS This is the first CADASIL series in which multiple circulating biomarkers have been studied. Our findings support previous studies on the presence and the possible modulating effect of endothelial impairment in the disease. Furthermore, our research data suggest that blood CPCs may be markers of disease severity.

Abstract
PURPOSES The aim of the present study was to examine whether a replacement diet with products made with organic ancient khorasan wheat could provide additive protective effects in reducing glucose, insulin, lipid and inflammatory risk factors, and in restoring blood redox balance in type 2 diabetes mellitus (T2DM) patients compared to diet with product made with modern organic wheat. METHODS We conducted a randomized, double-blinded crossover trial with two intervention phases on 21 T2DM patients (14 females, 7 males). The participants were assigned to consume products (bread, pasta, crackers and biscuits) made using semi-whole flour from organic wheat that was either from ancient khorasan wheat or modern control wheat for 8 weeks in a random order. An 8-week washout period was implemented between the interventions. Laboratory analyses were performed both at the beginning and at the end of each intervention phase. RESULTS The metabolic risk profile improved only after the khorasan intervention period, as measured by a reduction in total and LDL cholesterol (mean reduction: -3.7 and -3.4 %, respectively), insulin (-16.3 %) and blood glucose (-9.1 %). Similarly, there was a significant reduction in circulating levels of reactive oxygen species (ROS), vascular endothelial growth factor (VEGF) and interleukin-1ra, and a significant increase of total antioxidant capacity (+6.3 %). No significant differences from baseline were noted after the modern control wheat intervention phase. The change (from pre- to post-intervention) between the two intervention arms was significantly different (p < 0.05) for total and LDL-c, insulin and HOMA index. CONCLUSIONS A replacement diet with ancient khorasan wheat consumption provided additive protection in reducing total and LDL cholesterol, insulin, blood glucose, ROS production, and some inflammatory risk factors, which are all key factors warranting of control in secondary prevention of T2DM compared to a diet with products made with modern wheat.

Abstract
The aim of the study was to evaluate the association between circulating (CPCs) and endothelial (EPCs) progenitor cells and left ventricular (LV) remodeling in chronic heart failure (HF). 85 HF patients, ranging 29-89 years, 83.5% males, 45.9% ischemic, NYHA functional class II-IV, with a LV ejection fraction ≤40% were studied. LV ejection fraction, LV end-diastolic and end-systolic (LVESV) volumes, LV mass and tricuspid annular plane systolic excursion (TAPSE) were evaluated, and, when indicated, indexed for body surface area (BSA). CPCs and EPCs number was assessed using flow cytometry. CPCs were defined as CD34+, CD133+ and CD34+/CD133+. EPCs, identified through their expression of KDR, were defined as CD34+/KDR+, CD133+/KDR+ and CD34+/CD133+/KDR+. All EPCs were negatively related to LVESV/BSA (r = -0.24, p = 0.02 for all EPC's populations), and to LVmass/BSA (CD34+KDR+; r = -0.30, p = 0.005; CD133+KDR+; r = -0.31, p = 0.004; CD34+CD133+KDR+; r = -0.29, p = 0.007). No differences in EPCs levels in relation to cardiovascular risk factors, medications, etiology, age or gender were observed. CPCs number was higher in women, and lower in ischemic patients. In logistic regression analyses, the low EPCs' number was associated with an increased likelihood of abnormal LVmass/BSA. CPCs proved to be higher and EPCs lower in patients with severely abnormal LVmass/BSA (gr/m(2), ≥122 in women and ≥149 in men). Our results suggest a correlation between LV remodeling and progenitor cells. This is noteworthy considering that it has been suggested that bone marrow-derived EPCs participate in cardiac regeneration and function recovery in the setting of progressive HF.

Abstract
The aim of this study was to evaluate the effect of consuming gilthead sea bream fillets, with different n-6/ n-3 ratios, on atherosclerotic biomarkers. Twenty healthy subjects were included in a randomised single-blinded cross-over trial. Participants were randomized into 2 groups, both of which received approximately 630 g per week of gilthead sea bream fed with either 100% fishmeal (FM) or partial replacement with plant proteins (PP) over two consecutive 10 week periods, respectively. Group A consumed firstly the FM fillets followed by the PP fillets, whereas the reverse order was adopted for group B. Group A reported a significant decrease of 29.3% (Δ = -26 mg/dL) in total cholesterol after the first phase of the intervention, before returning to baseline levels after the dietary intervention with fish fed with PP. Similarly, in group A, both LDL-cholesterol and triglycerides decreased significantly by 21.6% (Δ = -19 mg/dL) and 11.7% (Δ = -10.7 mg/dL), respectively, before increasing again after the intervention. Improvements in the inflammatory cytokines, interleukin-6 and -8 were also noted. Moreover, whole blood viscosity appeared significantly improved in group A, as seen by a significant increase of 7.59% (Δ = +4.59 mPA) for erythrocyte filtration rate. In conclusion, similar EPA+DHA content with different n- 6/n-3 ratio fish flesh intake was shown to have varied affects on lipid, inflammatory and haemorheological parameters in a group of healthy subjects.

Abstract
During the last years increasing evidence showed that bone marrow-derived cells with angiogenic capability, named endothelial progenitor cells (EPCs), possess the capacity to home to sites of vascular injury, so contributing to the neoangiogenesis in vivo and to the maintenance of the homeostasis of vascular endothelium. Currently, potent triggers for the mobilisation of EPCs from bone-marrow are known. In addition to some pharmacological treatment such as statins, erythropoietin, PPAR-gamma agonists and angiotensin-II receptor antagonists, the effects of healthy lifestyle, via mobilization and functional improvement of EPC, is increasingly recognized. In this review we analyze, the effects of lifestyle interventions on EPCs. In particular we will focus on physical activity and cardiac rehabilitation protocols, weight reduction, and smoking cessation. Moreover, the negative effects of depression, mood disturbances and type D-personality on EPCs are also considered.

Abstract
BACKGROUND To assess the effect of a personalized physical activity programme on weight and circulating (CPC) and endothelial progenitor cells (EPC) in overweight and obese subjects. MATERIALS AND METHODS Anthropometric measurements with body composition, cardiopulmonary test, maximal stress exercise test with maximal oxygen uptake (VO(2max) ) and a series of biochemical analyses were taken before (T0) and after 3 months of physical activity (T1) in a total of 80 overweight and obese subjects. CPC and EPC were determined using flow cytometry and were defined as CD34+, CD133+ and CD34+/CD133+ for CPC and CD34+KDR+, CD133+KDR+ and CD34+CD133+KDR+ for EPC. RESULTS At the end of the programme, we divided the population into two groups, compliant individuals (group A, n = 47) and noncompliant individuals (group B, n = 33). Group A reported significant reductions of weight by 3·1% (P < 0·0001) and fat mass by 4·4% (P < 0·0001), while group B showed a percentage of increase in fat mass by 1·5% at T1. In group A, a trend of increase at T1 for circulating levels of CPC and EPC was observed, reaching the statistical significance for all the three types of EPC. On the contrary, group B showed no significant increase in CPC and EPC. Furthermore, a significant correlation between decrease in fat mass and increase in CD133+/KDR+ EPC was reported in group A (r = 0·50; P = 0·04). CONCLUSION Three months of physical activity significantly improved anthropometric measurements. A beneficial effect of increased number of EPC in compliant individuals, in relation to weight loss, was observed.

Abstract
OBJECTIVE Increasing evidence suggests an association between insomnia and cardiovascular disease. We performed a systematic review with meta-analysis of all the available prospective studies that investigated the association between insomnia and risk of developing and/or dying from cardiovascular disease. DESIGN Systematic review and meta-analysis of prospective cohort studies. METHODS We conducted an electronic literature search through MedLine, Embase, Google Scholar, Web of Science, The Cochrane Library and bibliographies of retrieved articles up to December 2011. Studies were included if they were prospective, had assessment of insomnia or sleep complaints at baseline, evaluated subjects free of cardiovascular disease at baseline and measured the association between insomnia and risk of developing and/or dying from cardiovascular disease. RESULTS After the review process 13 prospective studies were included in the final analysis. These studies included 122,501 subjects followed for a time ranging from three to 20 years. A total of 6332 cardiovascular events occurred during the follow-up. Insomnia was assessed through questionnaire and defined as either difficulty of initiating or maintaining sleep or presence of restless, disturbed nights. The cumulative analysis for all the studies under a random-effects model showed that insomnia determined an increased risk (+45%) of developing or dying from cardiovascular disease during the follow-up (relative risk 1.45, 95% confidence interval 1.29-1.62; p < 0.00001), with no evidence of heterogeneity across the studies (I 2: 19%; p = 0.14). CONCLUSION Insomnia is associated with an increased risk of developing and/or dying from cardiovascular disease.

Abstract
BACKGROUND Among the benefits of a cardiac rehabilitation (CR) program for patients after an acute coronary syndrome (ACS) is the mobilization of endothelial progenitor cells (EPCs). However not all patients respond to CR with an increase of EPC. We performed this study to identify the characteristics of patients who will not benefit from an increase of EPCs at the end of a CR program. METHODS 112 ACS patients were admitted to a four-week CR program. EPCs, high sensitivity C-reactive protein (hsCRP) and NT-ProBNP levels were determined at the beginning (T1) and at the end (T2) of the CR program. All patients performed a cardiopulmonary exercise test at T1 and at T2. EPCs were defined as CD34+KDR+, CD133+KDR+ and CD34+CD133+KDR+. hsCRP and NT-ProBNP were measured by nephelometric and immunometric method, respectively. RESULTS At T2, we observed a significant increase of EPCs (p=0.001), VO2 peak, Watt max HDL-cholesterol (p<0.0001) and a significant decrease (p<0.001) of hsCRP and NT-ProBNP, triglycerides, HbA1c, systolic blood pressure and waist circumference. Variations of VO2 peak were significantly correlated with the variations of EPCs. Patients with increased EPCs showed significantly (p=0.01) lower baseline levels of CRP and higher basal Watt max (p=0.04). In a multivariate logistic regression analysis, the lowest tertile of baseline hsCRP significantly affected the likelihood of having an increase of EPCs at the end of the CR program. CONCLUSIONS A CR program determines an increase of EPCs with a decrease of CRP and NT-ProBNP. A different trend for EPCs can be detected among patients correlated to CRP levels and exercise tolerance.

Abstract
INTRODUCTION Renal transplant recipients are at increased risk of cardiovascular morbidity and mortality. We assessed platelet reactivity and reticulated platelets (RPs) in 90 recipients, 51 (56.6%) of whom were not receiving acetylsalicylic acid (ASA) therapy (group A) and 39 (43.3%) who were receiving ASA therapy, 100 mg (group B), and in 60 healthy controls (group C). METHODS Reticulated platelets were measured using a hematology automated analyzer (XE-2100; Sysmex Corp, Kobe, Japan) and were expressed as the percentage of RPs in the total optical platelet count (immature platelet fraction [IPF]), as the percentage of highly fluorescent RPs, and as the absolute number of RPs (IPF#). Platelet function was assessed using optical aggregometry (platelet aggregation) induced using 1 mmol/L of arachidonic acid, 2 or 10 micromol/L of adenosine diphosphate, or 2 microg/mL of collagen. RESULTS Group A demonstrated significantly higher values of RP compared with group B or group C. Group B demonstrated a substantially higher percentage of RPs compared with group C, which was significant only for the IPF parameter. Multiple regression analysis demonstrated that IPF and IPF# were significantly and positively related to collagen-induced platelet aggregation. CONCLUSION We documented the presence of higher concentrations of RPs in transplant recipients compared with a control population, and a significant association between RPs and platelet function.

Abstract
Renal transplant recipients (RTRs) patients are at increased risk of cardiovascular morbidity and mortality. We aimed this study to assess reticulated platelets (RP), platelet reactivity and von Willebrand factor (vWF) levels in RTRs patients. In 150 RTRs patients [84 (56%) not on acetylsalicylic acid (ASA) treatment, group A; 66 (44%) on ASA 100 mg treatment, group B] and in 60 healthy control subjects, RP were measured by a Sysmex XE-2100 and were expressed as the percentage of RP of the total optical platelet count (immature platelet fraction; IPF), as the percentage of RP highly fluorescent (H-IPF) and as the absolute number of RP (IPF#). Platelet function was assessed by optical aggregometry (PA) induced by 1 mmol arachidonic acid (AA-PA), 2 and 10 μM ADP (ADP2-PA and ADP10-PA) and 2 μg/ml collagen (Coll-PA). vWF levels were measured by using a miniVidas analyser. Group A and group B showed significant higher values of RP than controls. At a multiple linear regression analysis IPF and IPF# were significantly and positively related to collagen-PA. By analysing group B according to residual platelet reactivity (RPR), we observed a significant higher number of RP among patients with RPR by collagen. Moreover at a multiple logistic regression analysis, IPF# significantly affected the risk of having a RPR by collagen. With regard to vWF, RTRs patients showed higher levels than control subjects. We documented a higher platelet turn-over in both groups of RTRs patients and increased platelet reactivity in RTRs patients not on ASA therapy than controls.

Abstract
BACKGROUND AND AIMS Non-alcoholic fatty liver disease (NAFLD) is a worldwide diffuse condition due to alimentary, environment and genetic factors. The aim of our preliminary study was to evaluate the effectiveness of long-term consumption of food enriched with n-3 polyunsaturated fatty acids (PUFA) in patients with NAFLD. METHODS Eleven patients were enrolled; six (four males, two females) were planned for oral administration of 6.5 ml olive oil enriched with n-3 PUFA for 12 months, while five (four males, one female) were used as controls. RESULTS Consumption of olive oil enriched with n-3 PUFA demonstrated a significant improvement of liver echo-texture and of the Doppler Perfusion Index after 12 months (after: 0.19 ± 0.02 vs. pre: 0.15 ± 0.03; P < 0.05), whereas no significant changes were seen at the end of follow-up in controls. Moreover, patients who consumed the olive oil enriched with n-3 PUFA showed a significant amelioration of liver enzymes, and of triglycerides (post: 132.8 ± 63.7 vs. pre: 164.5 ± 85.5 mg/dl; P = 0.04) in a general linear model adjusted for age and gender. Interestingly, patients reported to have a significant increase of adiponectin levels (post: 1,487.9 ± 96.7 vs. pre: 1,143 ± 24.8 μg/ml; P = 0.04). CONCLUSION The results of this preliminary study showed that long-term consumption of olive oil enriched with n-3 PUFA in patients with NAFLD is able to decrease circulating liver enzymes and triglycerides, with a significant improvement of adiponectin levels.

Abstract
BACKGROUND AND AIM Some studies recently reported a favourable effect for cis-9, trans-11 conjugated linoleic acid (CLA) on plasma lipoprotein profile of healthy subjects. Aim of this crossover intervention study was to evaluate the influence of a short-term dietary intake of a cheese derived from sheep's milk naturally rich in CLA on several atherosclerotic biomarkers, in comparison with a commercially available cheese. METHODS AND RESULTS Ten subjects (6 F; 4 M) with a median age of 51.5 followed for 10 weeks a diet containing 200 g/week of cheese naturally rich in CLA (intervention period) and for the same period a diet containing a commercially available cheese of the same quantity (placebo period). Consumption of the dairy product naturally rich in cis-9, trans-11 CLA determined a significant (p<0.05) reduction in inflammatory parameters such as interleukin-6 (pre: 8.08+/-1.57 vs. post: 4.58+/-0.94 pg/mL), interleukin-8 (pre: 45.02+/-5.82 vs. post: 28.59+/-2.64 pg/mL), and tumour necrosis factor-alpha (pre: 53.58+/-25.67 vs. post: 32.09+/-17.42 pg/mL) whereas no significant differences in the placebo period were observed. With regard to haemorheological parameters, the test period significantly ameliorated erythrocytes' filtration rate (pre: 7.61+/-0.71% vs. post: 9.12+/-0.97%; p=0.03) with respect to the placebo period. Moreover, a reduction in the extent of platelet aggregation, induced by arachidonic acid [pre: 87.8+/-1.76% vs. post: 77.7+/-3.56%; p=0.04] was observed during the test period in comparison with the placebo period. CONCLUSIONS Dietary short-term intake of the tested dairy product naturally rich in cis-9, trans-11 CLA appeared to cause favourable biochemical changes of atherosclerotic markers.

Abstract
The relationship between protein Z levels and thrombosis is controversial. We performed a systematic review and meta-analysis of the available studies to assess the association between protein Z and vascular thrombotic diseases. We conducted an electronic literature search through MedLine, Embase, Google Scholar, Web of Science, The Cochrane Library, bibliographies of retrieved articles and abstracts of congresses up to October, 2009. Studies were included if they analysed protein Z levels in patients with vascular thrombotic diseases. After the review process, 28 case-control studies (33 patient cohorts), including 4,218 patients with thrombotic diseases and 4,778 controls, were selected for analysis. The overall analysis using a random-effects model showed that low protein Z levels were associated with an increased risk of thrombosis (odds ratio [OR] 2.90, 95% confidence interval [CI] 2.05-4.12; p<0.00001). On subgroup analysis, a significant association was found between low protein Z levels and arterial vascular diseases (OR 2.67, 95%CI 1.60-4.48; p=0.0002), pregnancy complications (OR 4.17, 95%CI 2.31-7.52; p<0.00001), and venous thromboembolic diseases (OR 2.18, 95%CI 1.19-4.00; p=0.01). The results of this meta-analysis are consistent with a role for protein Z deficiency in thrombotic diseases, including arterial thrombosis, pregnancy complications and venous thromboembolism.

Abstract
BACKGROUND AND PURPOSE Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited disease due to cerebral microangiopathy presenting with variable pictures, including stroke, progressive cognitive impairment, and disability. Mechanisms leading from vessel structural changes to parenchymal damage and eventually to clinical expression are not fully understood. Among pathogenic processes, endothelial dysfunction has been hypothesized. Endothelial progenitor cells and circulating progenitor cells (CPCs) derived from bone marrow participate in endothelium structure and function maintenance and contribute to ischemic area revascularization. No data are available about these cells in CADASIL. Our objective in this study was to evaluate endothelial progenitor cells and CPCs role in CADASIL. METHODS Twenty-nine patients with CADASIL and 29 sex- and age-matched control subjects were enrolled. Cells were measured in peripheral blood using flow cytometry. Endothelial progenitor cells were defined as positive for CD34/KDR, CD133/KDR, and CD34/CD133/KDR; and CPCs as positive for CD34, CD133, and CD34/CD133. RESULTS Endothelial progenitor cells were significantly lower in patients with CADASIL than in control subjects (CD34/KDR: 0.05 versus 0.1 cells/microL, P=0.005; CD133/KDR: 0.07 versus 0.1 cells/microL, P=0.006; CD34/CD133/KDR: 0.05 versus 0.1 cells/microL, P=0.001). The difference remained significant after adjusting for age, sex, and statin use. CPCs were not significantly lower in CADASIL, but patients with stroke or dementia had significantly reduced CPC levels than patients without (CD34: 1.68 versus 2.95 cells/microL, P=0.007; CD133: 1.40 versus 2.82 cells/microL, P=0.004; CD34/CD133: 1.44 versus 2.75 cells/microL, P=0.004). CPC levels significantly correlated with cognitive and motor performance measures. CONCLUSIONS We have documented an association between endothelial progenitor cells and CPCs and CADASIL, extending previous data about the presence of endothelial dysfunction in this disease and its potential role in modulating phenotype.
