Increased Symmetric Dimethylarginine Level Is Associated with Worse Hospital Outcomes through Altered Left Ventricular Ejection Fraction in Patients …
2017
International audience; Objectives: We aimed to investigate whether SDMA-symmetric dimethylarginine-the symmetrical stereoisomer of ADMA-might be a marker of left ventricular function in AMI.Background: Asymmetric dimethylarginine (ADMA) has been implicated in the prognosis after acute myocardial infarction (AMI) and heart failure (HF).Methods: Cross sectional prospective study from 487 consecutive patients hospitalized 2, and death.Results: Patients were analysed based on SDMA tertiles. Sex, diabetes, dyslipidemia, and prior MI were similar for all tertiles. In contrast, age and hypertension increased across the tertiles (p<0.001). From the first to the last tertile, GRACE risk score was e…
Field evaluation of a rapid antigen test (Panbio™ COVID-19 Ag Rapid Test Device) for COVID-19 diagnosis in primary healthcare centres.
2021
Abstract Objectives To our knowledge no previous study has assessed the performance of a rapid antigen diagnostic immunoassay (RAD) conducted at the point of care (POC). We evaluated the Panbio™ COVID-19 Ag Rapid Test Device for diagnosis of coronavirus 2019 disease (COVID-19) in symptomatic patients (n = 412) attending primary healthcare centres. Methods RAD was performed immediately after sampling following the manufacturer's instructions (reading at 15 min). RT-PCRs were carried out within 24 h of specimen collection. Samples displaying discordant results were processed for culture in Vero E6 cells. Presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in cell cultures…
Increased ischemic stroke, acute coronary artery disease and mortality in patients with granulomatosis with polyangiitis and microscopic polyangiitis.
2018
International audience; Objective: The aim of our study was to assess major cardiovascular event incidence, predictors, and mortality in ANCA-associated vasculitis (AAV).Methods: We conducted a retrospective cohort study of all GPA or MPA, according to Chapel Hill Consensus Conference classification criteria, diagnosed between 1981 and 2015. Major cardiovascular event was defined as acute coronary artery disease, or ischemic stroke, or peripheral vascular disease requiring a revascularization procedure. We calculated the comparative morbidity/mortality figure (CMF) and we used Cox proportional hazards regression models to assess the risk of coronary artery disease, ischemic stroke associate…
Induced post-traumatic apexification: 20 year follow-up and morphological study after new fracture.
2018
Apexification is an endodontic technique used in immature necrotic teeth, the primary goal of which is to induce a calcified barrier in roots with open apices and to promote the continuation of apical root development. A 7-year-old patient with a coronal fracture in a maxillary central incisor was treated with an apexification technique using calcium hydroxide. The apical closure was obtained after one year, then a permanent root canal filling was performed. The tooth was monitored for a period of 20 years, up to when a trauma caused its extraction. The newly formed root was analyzed macroscopically, histologically and through scanning electron microscopy. A morphologically normal root was …
Ticagrelor, but not clopidogrel, reduces arterial thrombosis via endothelial tissue factor suppression
2017
The P2Y12 antagonist ticagrelor reduces mortality in patients with acute coronary syndrome (ACS), compared with clopidogrel, and the mechanisms underlying this effect are not clearly understood. Arterial thrombosis is the key event in ACS; however, direct vascular effects of either ticagrelor or clopidogrel with focus on arterial thrombosis and its key trigger tissue factor have not been previously investigated.Methods and results: Human aortic endothelial cells were treated with ticagrelor or clopidogrel active metabolite (CAM) and stimulated with tumour necrosis factor-alpha (TNF-α); effects on procoagulant tissue factor (TF) expression and activity, its counter-player TF pathway inhibito…
Homocysteine concentration in coronary artery disease: Influence of three common single nucleotide polymorphisms.
2017
Whether single nucleotide polymorphisms (SNPs) of homocysteine metabolism enzymes influence the rate of cardiovascular (CV) events in coronary artery disease (CAD) patients remains controversial.In this analysis, 1126 subjects from the AtheroGene study with CAD and 332 control subjects without known CAD were included. The following SNPs were investigated: methylentetrahydrofolate reductase (MTHFR-C667T), methionin synthetase (MS-D919G), and cystathionin beta synthetase (CBS-I278T). The endpoint was the combination of cardiovascular death, stroke, and non-fatal myocardial infarction (N = 286). The median follow-up time was 6.4 years. Kaplan-Meier curve analysis showed an increasing event rat…
Short-term Changes in Gal 3 Circulating Levels After Acute Myocardial Infarction.
2016
Background and Aims Galectin 3 (Gal 3) is a β-galactoside-binding lectin known to play a part in inflammation, adverse remodeling and fibrosis. Gal 3 seems to be linked to atherogenesis and Coronary Artery Disease (CAD), but less is known about the relationship between Gal 3 and acute myocardial infarction (AMI). The aim of the present study is to assess circulating levels of Gal 3 after AMI and to evaluate short-term changes of the biomarker within 5 days from the acute event. Methods Two hundred fifteen confirmed AMI patients (125 STEMI, M/F = 2.8; mean age: 65.4 ± 13.8 years) were enrolled in the present study; two blood samples were collected from each patient: first, within 1 h from ad…
Associations between cardiovascular disease, cancer, and very low high-density lipoprotein cholesterol in the REasons for Geographical and Racial Dif…
2018
AbstractAimsRelatively little is known about the health outcomes associated with very low plasma concentrations of high-density lipoprotein cholesterol (HDL-C) mainly because of the small numbers of individuals with such extreme values included in clinical trials. We, therefore, investigated the association between low and very low HDL-C concentration at baseline and incident all-cause-mortality, death from malignant disease (i.e. cancer), and with fatal or non-fatal incident coronary heart disease (CHD) in individuals from the Reasons for Geographical And Racial Differences in Stroke (REGARDS) study.Methods and resultsAnalysis was based on 21 751 participants from the REGARDS study who wer…

Epidemiologic and Clinical Characteristics of Coronavirus and Bocavirus Respiratory Infections after Allogeneic Stem Cell Transplantation: A Prospect…
2018
Highlights • Human coronavirus are common after allogeneic stem cell transplantation and can progress to LRTDs, and in some cases this leads to hospitalization and requires supportive care. • Human bocavirus are quite rare after allogeneic stem cell transplantation and are commonly detected in conjunction with other viral co-pathogens.
