Polycythemia Vera as a Predisposing Factor for Aortic Stenosis: Prevalence and Correlation with Blood Cells Count and Mutational Status

2008

Abstract The association between Polycythemia Vera (PV) and thrombosis is multi-factorial involving the complex interaction between activated leukocytes, platelets and endothelium. Recent reports have postulated that PV patients may over express adhesive molecules on red cell surface, likely by JAK2 mutation (Wautier M et al. Blood.2007;110(3):894–901). This process activates endothelium with production of vascular growth factors and other mechanisms leading to atherosclerosis. Aortic Stenosis (AS) is the commonest valvular heart disease in western countries; its pathogenesis is mainly related to a degenerative process sharing many characteristics with atherosclerosis. At the present is not…

Transdermal estrogens do not appear to modify the extent of lesional areas of aortic atherosclerosis in oophorectomized rabbits on a cholesterol-rich…

2000

Cardiovascular disease (CVD) is the leading cause of death in older women in industrialised countries. It has been suggested that it is the cessation of estrogen production by the ovaries that puts postmenopausal women at increased risk of CVD. Estrogen therapy has demonstrated a protective effect against CVD and several reports suggest that diverse mechanisms may be involved. Oral estrogen appears to be associated with a better lipid profile than the use of transdermal estrogens; however, it is assumed that estrogens, oral and non-oral, have direct actions on the blood vessels that may exert an important role in cardiovascular disease prevention. To investigate the effect of transdermal es…

CA125 but not NT-proBNP predicts the presence of a congestive intrarenal venous flow in patients with acute heart failure

2021

Abstract Background Intrarenal venous flow (IRVF) measured by Doppler ultrasound has gained interest as a potential surrogate marker of renal congestion and adverse outcomes in heart failure. In this work, we aimed to determine if antigen carbohydrate 125 (CA125) and plasma amino-terminal pro-B-type natriuretic peptide (NT-proBNP) are associated with congestive IRVF patterns (i.e., biphasic and monophasic) in acute heart failure (AHF). Methods and results We prospectively enrolled a consecutive cohort of 70 patients hospitalized for AHF. Renal Doppler ultrasound was assessed within the first 24-h of hospital admission. The mean age of the sample was 73.5 ± 12.3 years; 47.1% were female, and…

Increased nitrotyrosine plasma levels in relation to systemic markers of inflammation and myeloperoxidase in chronic heart failure

2009

The presence of a reciprocal link between inflammation and oxidative/nitrosative stress has been postulated in chronic heart failure (CHF). We aimed to determine signs of nitrosative stress in serum/plasma of CHF patients. ELISA tests were used for quantification of serum/plasma levels of Nitrotyrosine (NT), H(2)O(2), total NO, nitrite (NO(2)(-)), myeloperoxidase (MPO), Tumor Necrosis Factor-alpha (TNFalpha) and pro-Brain Natriuretic Peptide (proBNP) in 66 CHF patients (9 in NYHA I, 34 NYHA II, 23 NYHA III) and in 14 age-matched healthy subjects. NT levels were higher in NYHA III CHF patients compared to NYHA II (p<0.05), NYHA I (p<0.03) and controls (p<0.02), whereas NO(2)(-) and total NO …

Prognostic value of NT-proBNP and CA125 across glomerular filtration rate categories in acute heart failure.

2021

This study aimed to evaluate whether glomerular filtration rate (eGFR) during admission modifies the predictive value of plasma amino-terminal pro-brain natriuretic peptide (NT-proBNP) and carbohydrate antigen 125 (CA125) in patients hospitalized for acute heart failure (AHF).We retrospectively evaluated 4595 patients consecutively discharged after admission for AHF at three tertiary-care hospitals from January 2008 through October 2019. To investigate the effect of kidney function on the association of NT-proBNP and CA125 with 1-year mortality (all-cause and cardiovascular mortality), we stratified patients according to four eGFR categories:30 mL•minAt 1-year follow-up, 748 of 4595 (16.3%)…

Early Spot Urinary Sodium and Diuretic Efficiency in Acute Heart Failure and Concomitant Renal Dysfunction

2020

&lt;b&gt;&lt;i&gt;Objective:&lt;/i&gt;&lt;/b&gt; In acute heart failure (AHF), early assessment of spot urinary sodium (U&lt;sub&gt;Na&lt;/sub&gt;) has emerged as a useful biomarker for risk stratification and monitoring. The objective of this study was to investigate (a) whether early spot U&lt;sub&gt;Na&lt;/sub&gt; predicts 24-h diuretic efficiency and (b) the clinical factors associated with early spot U&lt;sub&gt;Na&lt;/sub&gt; in patients with AHF and concomitant renal dysfunction (RD). &lt;b&gt;&lt;i&gt;Methods:&lt;/i&gt;&lt;/b&gt; This is a post hoc analysis of the IMPROVE-HF trial, in which 160 patients with AHF and RD (estimated glomerular filtrate rate [eGFR] &amp;#x3c;60 mL/min/1…

OP0048 Outcomes in Systemic Lupus Erythematous (SLE) Patients Treated with Belimumab in Clinical Practice Settings: Results from the Observe Study in…

2014

Background Large-scale clinical trials have demonstrated clinical efficacy of belimumab in SLE patients. Objectives This study examined the clinical outcomes associated with belimumab in clinical practice settings in Germany. Methods OBSErve (GSK 117214) is a multi-center retrospective medical chart review study. Twenty-one rheumatologists from Germany treating >10 SLE-patients annually and with at least >5 yrs of practice experience were selected for data reporting. Adult SLE patients meeting the ACR classification criteria who received belimumab (10mg/kg) as part of usual care were identified for chart abstraction. Index date was the date of belimumab initiation. The primary outcome measu…

Impact of Proportionality of Secondary Mitral Regurgitation on Outcome After Transcatheter Mitral Valve Repair

2020

The purpose of this paper was to evaluate the impact of proportionality of secondary mitral regurgitation (SMR) in a large real-world registry of transcatheter edge-to-edge mitral valve repair (TMVr) BACKGROUND: Differences in the outcomes of recent randomized trials of TMVr for SMR may be explained by the proportionality of SMR severity to left ventricular (LV) volume.The ratio of pre-procedural effective regurgitant orifice area (EROA) to LV end-diastolic volume (LVEDV) was retrospectively assessed in patients undergoing TMVr for severe SMR between 2008 and 2019 from the EuroSMR registry. A recently proposed SMR proportionality scheme was adapted to stratify patients according to EROA/LVE…

Prescription of Antibiotic Prophylaxis for Dental Implant Surgery in Healthy Patients: A Systematic Review of Survey-Based Studies

2021

Background: Systemic antibiotic prophylaxis is frequently prescribed by dentists performing dental implant surgery to avoid premature implant failure and postoperative infections. The scientific literature suggests that a single preoperative dose suffices to reduce the risk of early dental implant failure in healthy patients.Material and Methods: A systematic review was made based on an electronic literature search in the PubMed-Medline, Embase, Web of Science, Scopus and Open Gray databases. The review addressed the question: “which antibiotic prophylaxis regimens are being used in dental implant surgery in healthy patients according to survey-based studies?” The identification, screening,…
