Abstract
This study aimed to apply the recently proposed Oslo hand osteoarthritis magnetic resonance imaging (MRI) scoring system to evaluate MRI findings in a cohort of patients affected by long-standing erosive hand osteoarthritis (EHOA). Eleven female EHOA patients (median 59 [interquartile range 62-52] years, disease duration 9.5 [interquartile range 13-3.75] years) underwent MRI (1.5 T) of the dominant hand, and synovitis, bone marrow lesions (BMLs), joint space narrowing, osteophytes, cysts, malalignment, and erosions were scored using the Oslo scoring system. Intra- and inter-reader reliability were assessed. The patients also underwent X-ray examination, and bone features were evaluated using the same scoring system. Pain and tenderness were assessed during a physical examination. Spearman's non-parametric test was used to analyze the correlations between variables. MRI intra- and inter-reader reliability were found between good and moderate for many features. No statistical differences were found between the radiographs and MRI with regard to detection of JSN, malalignment, and bone erosions. Synovitis was detected in 39.8 % of the 80 joints examined (in a mild form in 80 %), erosions were found in 51.1 %, and BMLs were identified in 20.5 and 23.9 % at the distal and the proximal side, respectively. BMLs at both the proximal and distal ends were correlated with tender joints (BML distal p = 0.0013, BML proximal p = 0.012). The presence of synovitis was correlated with tenderness (p = 0.004) and erosions at both the distal and proximal joints (p = 0.004). The presence of erosions correlated with tender joints (p < 0.01) and the mean visual analog scale (VAS) score (distal p = 0.03, proximal p = 0.01). Synovitis and BMLs were correlated with clinical symptoms in our patients affected with long-standing EHOA.

Abstract
Matrix Gla protein (MGP) and bone Gla protein (BGP) are two vitamin K-dependent proteins (VKDPs) involved in the regulation of vascular calcification (VC). We carried out a secondary analysis of the VIKI study to evaluate associations between drug consumption and VKDP levels in 387 hemodialyzed patients. The VIKI study assessed the prevalence of vitamin K deficiency in hemodialysis patients. We evaluated drug consumption, determined BGP and MGP levels, and verified the presence of any vertebral fractures (VF) and VC by spine radiographs. Total BGP levels were twice as high with calcimimetics versus no calcimimetics (290 vs. 158.5 mcg/L, p < 0.0001) and 69 % higher with vitamin D analogs (268 vs. 159 mcg/L, p < 0.0001). Total MGP was 19 % higher with calcimimetics (21.5 vs. 18.1 mcg/L, p = 0.04) and 54 % higher with calcium acetate (27.9 vs. 18.1 mcg/L, p = 0.003); no difference was found with vitamin D analogs (21.1 vs. 18.3 mcg/L, p = 0.43). Median Total BGP level was 29 % lower in patients with ≥1 VF (151 vs. 213 mcg/L, p = 0.0091) and 36 % lower in patients with VC (164 vs. 262.1 mcg/L, p = 0.0003). In non-survivors, median BGP and MGP were lower, but only for MGP this difference reached the statistical significance (152 vs. 191 mcg/L, p = 0.20 and 15.0 vs. 19.7 mcg/L, p = 0.02, respectively). Pending studies on vitamin K supplementation, calcimimetics, and vitamin D analogs may play a role in preserving vitamin K-dependent protein activity, thus contributing to bone and vascular health in CKD patients.

Abstract
UNLABELLED ESSENTIALS: Thrombosis is a major comorbidity in patients with chronic obstructive pulmonary disease (COPD). Roflumilast is a selective phosphodiesterase type-4 (PDE4) inhibitor approved for treatment of severe COPD. PDE4 blockade by roflumilast inhibits prothrombotic functions of neutrophils and monocytes. PDE4 inhibitors may reduce thrombotic risk in COPD as well as in other vascular diseases. BACKGROUND Roflumilast, an oral selective phosphodiesterase type 4 inhibitor, is approved for the treatment of severe chronic obstructive pulmonary disease (COPD). A recent meta-analysis of trials on COPD revealed that treatment with roflumilast was associated with a significant reduction in the rate of major cardiovascular events. The mechanisms of this effect remain unknown. OBJECTIVES We tested the hypothesis that roflumilast N-oxide (RNO), the active metabolite of roflumilast, curbs the molecular mechanisms required for leukocyte-platelet (PLT) interactions and prevents the prothrombotic functions of polymorphonuclear leukocytes (PMNs) and monocytes (MNs). METHODS Using well-characterized in vitro models, we analysed the effects of RNO on: (i) PMN adhesiveness; (ii) the release of neutrophil extracellular traps (NETs); and (iii) tissue factor expression in MNs. Key biochemical events underlying the inhibitory effects of RNO were defined. RESULTS AND CONCLUSIONS In PMNs, RNO prevented phosphoinositide 3-kinase (PI3K)-dependent phosphorylation of Akt on Ser473, and Src family kinase (SFK)-mediated Pyk2 phosphorylation on Tyr579-580, while inducing protein kinase A-mediated phosphorylation of C-terminal Src kinase, the major negative regulator of SFKs. Modulation of these signaling pathways by RNO resulted in a significant impairment of PMN adhesion to activated PLTs or human umbilical vein endothelial cells, mainly mediated by inhibition of the adhesive function of Mac-1. Moreover RNO curbed SFK/PI3K-mediated NET release by PMNs adherent on fibrinogen-coated surfaces. In MNs interacting with activated PLTs, RNO curbed PI3K-mediated expression of tissue factor. The efficacy of RNO was significantly potentiated by formoterol, a long acting β-adrenergic receptor agonist. This study reveals novel antithrombotic activities by which roflumilast may exert protective effects against cardiovascular comorbodities in COPD.

Abstract
Anti-tumor necrosis factor (TNF) alpha therapy has changed the course of psoriatic arthritis (PsA), but clinical experience about lengthening of time intervals between drug administrations is still limited. The aims of the study were to evaluate: (1) the long-term efficacy (over a 4-year period) of etanercept/adalimumab in a subset of PsA patients who did not require switches; and (2) the progressive lengthening of time intervals between treatments in patients who achieved minimal disease activity (MDA). PsA outpatients attending the Rheumatology Clinic-University of Padova who took a single anti-TNF agent (etanercept/adalimumab) for a 4-year period were studied. Therapy efficacy was assessed using clinical, biochemical, and disease activity (DA) indexes. The intervals between treatments were empirically and progressively lengthened after MDA was reached and maintained. One hundred and forty-one patients (mean age, 51.22 ± 12.34 years; mean disease duration, 12.1 ± 8.42 years) treated with etanercept/adalimumab (47.5% and 52.5%, respectively) were studied. DA indexes showed a marked, persistent improvement in all the patients throughout 4 years. The interval between injections could be extended in 46.1% of the patients (35% for adalimumab, 58% for etanercept) without provoking relapses. The mean therapy interval at the end of the study period was 3.12 weeks for adalimumab 40 mg (with respect to 2 weeks) and 2.75 weeks for etanercept 25 mg (with respect to 0.5 weeks). The new therapy timetable also led to cost savings. In conclusion, lengthening the time intervals between injections of anti-TNF agents in PsA patients who reach MDA is safe, effective, cost-effective, and facilitates patient compliance.

Abstract
BACKGROUND With patients referred to emergency departments (EDs) for acute dyspnea, emergency physicians should consider all possible diagnoses and assess patients' risk stratification. Copeptin has been shown to have prognostic power for subsequent events, such as death and rehospitalization in patients admitted for dyspnea. The aim of this study was to investigate prognostic role of copeptin variations during hospitalization in patients admitted for dyspnea. METHODS We conducted a prospective, multicentric, observational study in acute dyspneic patients in three ED centers in Italy. Clinical data and copeptin assessments were performed at admission, and at discharge. A 90-day follow-up was performed. RESULTS A total of 336 patients were enrolled, and on the basis of final diagnosis distinguished into two groups: acute heart failure and no acute heart failure. Compared to a control group, in all studied population copeptin values at admission resulted in a significantly (p<0.001) higher median (maximum-minimum): 31 (0-905) versus 8 (0-13) pmol/L. Median copeptin value at admission was 42 (0-905) pmol/L in acute heart failure patients and 20 (0-887) pmol/L in no acute heart failure, respectively (p<0.001). In all studied patients and in each group copeptin at admission and discharge showed significant predictive value for 90-day events (p<0.001). Furthermore, in all patients population and in both groups Δ copeptin values from admission to discharge also showed significant predictive value for 90-day events (p<0.001). CONCLUSIONS In patients admitted for acute dyspnea, admission, discharge and Δ copeptin variations have significant prognostic value from subsequent 90-day death and rehospitalization.

Abstract
BACKGROUND The Spine Deformity Index (SDI) is a measure of vertebral fractures (VFs), providing information on both their number and severity. METHODS We evaluated the relationships between SDI and clinical, biochemical and arterial calcification parameters in 387 hemodialysis (HD) patients. VFs, assessed by quantitative vertebral morphometry, and vascular calcifications were identified in the same lateral spinal X-ray. To improve the detection of fracture severity, we created a corrected SDI (c-SDI), by dividing SDI for the number of VFs. We assessed routine biochemistry, bone-Gla-protein (BGP), undercaboxylated BGP (ucBGP), and matrix-Gla-protein (MGP). RESULTS VFs prevalence was 55.3%. HD patients with a SDI >1 were more frequently males (p<0.05), and had lower BGP (p<0.01). Patients with a c-SDI >1 had higher LDL-cholesterol (p<0.05) and lower ucBGP (p<0.05) and MGP (p<0.05). Calcifications of the abdominal aorta (AAoC) were more frequent in patients with SDI >1 (p<0.05) and with c-SDI >1 (p<0.05). Multivariate logistic regression showed that male sex (OR 1.86, CI 1.20-2.91), age (OR 1.03, CI 1.01-1.05) and albumin ≥3.5 g/dL (OR 0.54, CI 0.31-0.93) were predictors of a SDI >1. Age (OR 1.05, CI 1.03-1.07), LDL-cholesterol (OR 1.74, CI 1.04-2.92) and ucBGP (OR 0.35, CI 0.18-0.70) were associated with c-SDI >1. CONCLUSIONS We conclude that the severity of VFs was associated with age, atherogenic factors and bone metabolism markers.

Abstract
OBJECTIVE Platelet-neutrophil interactions play a key role in cardiovascular disease and inflammatory processes. Src family kinases mediate P-selectin glycoprotein ligand-1-Mac-1 cross talk necessary for firm platelet-neutrophil adhesion. Because Src family kinase activity can be regulated by cAMP-dependent pathways, in this work, we evaluated the role of phosphodiesterases in the signaling events that are required to sustain platelet-neutrophil interactions and neutrophil recruitment at the site of vascular injury. APPROACH AND RESULTS In neutrophils exposed to P-selectin, selective phosphodiesterase 4 (PDE4) inhibition prevented Src family kinase-mediated phosphorylation of the proline-rich tyrosine kinase 2 on Tyr579/Tyr580. The effects of PDE4 inhibition required protein kinase A, likely through protein kinase A-mediated activation of COOH-terminal Src kinase, a major negative regulator of Src family kinases. PDE4, but not other phosphodiesterase inhibitors, reduced platelet-neutrophil conjugates as well as neutrophil firm adhesion on spread platelets under flow conditions. The effect of PDE4 inhibition on neutrophil adhesion was primarily mediated by downregulation of P-selectin-induced activation of Mac-1. In a murine model of endovascular injury, selective inhibition of PDE4 significantly reduced neutrophil recruitment at the site of vascular damage. CONCLUSIONS This study identifies PDE4 as a central node in the signaling network that mediates platelet-neutrophil adhesion and suggests that pharmacological inhibition of PDE4 may represent a novel therapeutic avenue for the treatment of cardiovascular disease.

Abstract
BACKGROUND & AIMS Body hydration changes continuously in hemodialysis patients. The Subjective Global Assessment (SGA) is used for the nutritional evaluation but it does not allow a direct evaluation of hydration. Bioelectrical impedance vector analysis (BIVA) is very sensitive to hydration. The potential of the combined evaluation of hydration and nutrition with SGA and BIVA is still lacking. METHODS Observational cross-sectional study on 130 (94 Male) uremic patients undergoing chronic hemodialysis three times a week. Nutritional status was evaluated with the SGA. Each subject was classified as SGA-A (normal nutritional status), SGA-B (moderate malnutrition), or SGA-C (severe malnutrition). Body hydration was evaluated with BIVA. The two vector components resistance (R) and reactance (Xc) were normalized by the subject's height and standardized as bivariate Z-score, i.e. Z(R) and Z(Xc). RESULTS Undernutrition influenced impedance vector distribution both before and after a dialysis session. In pre-dialysis, the mean vector of SGA A was inside the 50% tolerance ellipse. In SGA B and C, Z(R) was increased and Z(Xc) decreased, indicating a progressive loss of soft tissue mass. Fluid removal with dialysis increased both Z(R) and Z(Xc) in SGA A and B but not in C. With ROC curve analysis on the slope of increase, we found the cutoff value of 27.8° below which undernutrition was present, either moderate or severe. The area under the ROC curve was 77.7° (95% CI 69.5-84.5, P < .0001) with sensitivity 75.9%, specificity 78.6%, positive predicted value 74.6%, and negative predicted value 79%. CONCLUSIONS The distribution of impedance vectors is associated with the SGA classification of patients. The change in body hydration in each SGA category can be detected with BIVA.

Abstract
Prasugrel, through its active metabolite, reduces atherothrombosis and its clinical manifestations by inhibiting platelet activation and aggregation. Platelets also contribute to inflammation through interaction with different classes of leukocytes. We investigated whether the inhibitory effect of prasugrel on platelets also counteract inflammatory responses. The effect of prasugrel active metabolite, R-138727, was investigated on platelet P-selectin expression, platelet adhesion to polymorphonuclear leukocytes (PMN) and monocytes (MN) and Mac-1 expression in PMN and MN, in vitro, in human cells. The ex vivo effect of prasugrel administration on P-selectin, thromboxane (TXB)2 formation, platelet-PMN conjugates and Mac-1 expression in PMN triggered by PAR-4 agonist peptide was examined in whole blood from healthy mice as well as from mice in which an acute inflammatory reaction was induced by treatment with endotoxin. The effect of prasugrel on inflammatory markers in endotoxin-treated animals was also tested in vivo. R-138727 inhibited agonist-stimulated expression of platelet P-selectin, platelet-PMN and platelet-MN adhesion and platelet-dependent Mac-1 expression in leukocytes. Addition of aspirin did not modify the inhibitory effect elicited by R-138727. Treatment of mice with prasugrel resulted in a profound inhibition of platelet P-selectin expression, TXB2 production, platelet-PMN adhesion and Mac-1 expression in PMN induced by ex vivo stimulation with PAR-4 agonist peptide of whole blood from healthy or endotoxin-treated mice. Measurement of markers revealed that prasugrel reduced TXB2 and tumour necrosis factor-α synthesis and increased nitric oxide metabolites in endotoxin-treated mice in vivo. In conclusion, prasugrel reduces platelet interactions with PMN and MN. Through these effects prasugrel may curb platelet-mediated inflammatory responses.

Abstract
We studied the effects of 17β-estradiol (E₂) (10, 40 nM) on 2 vasoprotective pathways, i.e. cyclooxygenase-2 (COX-2)-dependent prostanoids and the antioxidant heme oxygenase-1 (HO-1), in human umbilical vein endothelial cells (HUVEC) exposed for 6h to steady laminar shear stress (LSS, 10 dyn/cm²), characteristic of atherosclerotic lesion-protected areas. COX-2 was induced by LSS versus static condition (SC). E₂ did not significantly affect COX-2 expression in HUVEC cultured in SC or exposed to LSS. Prostacyclin (PGI₂) and prostaglandin (PG)E₂ were induced while PGF(2α) was reduced by LSS. E₂ caused no effect or a small reduction of prostanoid biosynthesis. In HUVEC cultured in SC or exposed to LSS, E₂ 10 nM caused a comparable HO-1 induction (35-45%) while E₂ 40 nM was 5-fold more potent in LSS-exposed HUVEC than in SC (290% and 58%, respectively). PGI₂ receptor antagonist RO3244794 did not affect HO-1 induction by E₂. In conclusion, E₂ may restrain oxidant stress in the endothelium through HO-1 induction by a mechanism independent on PGI₂ signaling.

Abstract
BACKGROUND AND AIM Elevated serum phosphate and calcium-phosphate levels play an important role in the pathogenesis of vascular calcifications in uraemic patients and appear to be associated with increased cardiovascular mortality. We aimed to evaluate the effects of a partial replacement of food protein with a low-phosphorus and low-potassium whey protein concentrate on phosphate levels of dialysis patients with hyperphosphataemia. METHODS AND RESULTS Twenty-seven patients undergoing chronic haemodialysis were studied for a 3-month period. In the intervention group (n = 15), food protein were replaced by 30 or 40 g of low-phosphorus and low-potassium protein concentrate aimed at limiting the phosphate intake. In the control group (n = 12) no changes were made to their usual diet. Anthropometric measurements, biochemical markers and dietary interviews were registered at baseline and during the follow-up period. From baseline to the end of the study, in the intervention group, serum phosphate and circulating intact parathyroid hormone levels lessened significantly (8.3 ± 1.2 mg/dL vs 5.7 ± 1.4 mg/dL and 488 ± 205 pg/ml vs 177 ± 100 pg/ml respectively; p < 0.05) with decreasing of phosphate and potassium intake. No significant differences were found in the control group. No significant changes were observed in serum albumin, calcium, potassium, Kt/V, body weight and body composition in both the intervention and control groups. CONCLUSION Dietary intake of phosphate mainly comes from protein sources, so dietary phosphorus restriction may lead to a protein/energy malnutrition in a dialysis patient. A phosphorus-controlled diet plan including a nutritional substitute resulted in serum phosphate and intact parathyroid hormone decrease without nutritional status modifications in dialysis patients.

Abstract
BACKGROUND In end-stage renal disease (ESRD) hyperphosphatemia associates with vascular calcifications and cardiovascular events derived from endothelial dysfunction. In dialysis patients, C-reactive protein (CRP), a marker of inflammation, associates with cardiovascular mortality. Increased PO(4) concentration impairs endothelial integrity via induction of oxidative stress, and sevelamer, a phosphate binder, showed anti-inflammatory effect reducing CRP, which paralleled PO(4) reduction. To give support to a direct proinflammatory role of hyperphosphatemia "per se," we have considered previously studied dialysis patients with sevelamer-"resistant" hyperphosphatemia, who were treated with a chitosan-loaded chewing gum, as salivary phosphate binder, in addition to sevelamer, reduced serum PO(4) to normal, to retrospectively evaluate their CRP and the relationship with hyperphosphatemia and calcium × phosphate (Ca × PO(4)) product. PATIENTS AND METHODS High sensitive (hs) CRP of 13 previously studied hemodialysis patients with sevelamer-resistant hyperphosphatemia was evaluated with immunonephelometry. RESULTS Chitosan chewing gum use reduced hsCRP (from 1.38 ± 0.61 to 0.39 ± 0.16 mg/L after the gum, p < 0.0002), which returned to baseline after 4 weeks from gum discontinuation (1.25 ± 0.41). hsCRP reduction paralleled serum PO(4) reduction: from 7.60 ± 0.91 mg/dL to 5.18 ± 0.73 (after the gum) (p < 0.00001), returning to baseline (7.55 ± 0.75) after gum discontinuation. hsCRP reduction directly correlated with PO(4) reduction (p = 0.029). CONCLUSION The relationship in sevelamer-resistant dialysis patients between the reduction of serum PO(4), induced by the chitosan-loaded chewing gum, and CRP reduction supports also in humans a proinflammatory role of hyperphosphatemia "per se" derived from "in vitro" studies. This further contributes to the high cardiovascular risk of ESRD patients making their serum phosphate in the normal range of vital importance.
