Long-Term Clinical Outcomes According to Previous Manifestations of Atherosclerotic Disease (from the FAST-MI 2010 Registry)
2017
IF 3.398; International audience; The prognosis of patients with acute myocardial infarction (AMI) has notably improved in the past 20 years. Using the French Registry of ST-Elevation and Non-ST-elevation Myocardial Infarction (FAST-MI) 2010 registry, we investigated whether previous manifestations of atherosclerotic disease (i.e., previous MI, or a history of any form of atherosclerotic disease) are at truly increased risk compared with those in whom AMI is the first manifestation of the disease. FAST-MI 2010 is a nationwide French registry including 3,079 patients with AMI, among whom 1,062 patients had a history of cardiovascular atherosclerotic disease and 498 patients had a history of …
Smoking and FOS expression from blood leukocyte transcripts in patients with coronary artery disease.
2011
International audience; OBJECTIVE: Analysis of the leukocyte transriptome, in particular the Finkel-Biskis-Jinkins Osteosarcoma (c-Fos) gene, which has a prominent role in inflammation, provides new insights into atherosclerosis mechanisms. Although smoking is a major risk factor, the links between smoking status and coronary artery disease (CAD) remains unclear. We aimed to analyze the relationship between smoking status and c-Fos expression in circulating leukocytes of patients with CAD. METHODS: c-Fos expression was measured by RT-Q-PCR, from blood leukocytes of 239 consecutive patients after acute myocardial infarction (MI). The patients were asked about their smoking status and stratif…
Cardiac rehabilitation and 5-year mortality after acute coronary syndromes: The 2005 French FAST-MI study.
2016
IF 2.271; International audience; Background. - Clinical studies have shown a beneficial effect of cardiac rehabilitation (CR) on mortality.Objective. - To study the effect of CR prescription at discharge on 5-year mortality in patients with acute myocardial infarction (AMI).Methods. - Participants, from the 2005 French FAST-MI hospital registry, were 2894 survivors at discharge, divided according to AMI type: ST-segment elevation myocardial infarction (STEMI; n=1523) and non-STEMI (NSTEMI; n=1371). The effect of CR prescription on mortality was analysed using a Cox proportional hazards model.Results. - At discharge, 22.1% of patients had a CR prescription. Patients referred to CR were youn…
Metabolomics Study of Urine in Autism Spectrum Disorders Using a Multiplatform Analytical Methodology
2015
International audience; Autism spectrum disorder (ASD) is a neurodevelopmental disorder with no clinical biomarker. The aims of this study were to characterize a metabolic signature of ASD and to evaluate multiplatform analytical methodologies in order to develop predictive tools for diagnosis and disease follow-up. Urine samples were analyzed using (1)H and (1)H-(13)C NMR-based approaches and LC-HRMS-based approaches (ESI+ and ESI- on HILIC and C18 chromatography columns). Data tables obtained from the six analytical modalities on a training set of 46 urine samples (22 autistic children and 24 controls) were processed by multivariate analysis (orthogonal partial least-squares discriminant …
Parenting Mechanisms in Links Between Parents’ and Adolescents’ Alcohol Use Behaviors
2007
Background: Adolescence has been identified as a critical period with regard to the initiation and early escalation of alcohol use. Moreover, research on familial risk and protective processes provides independent support for multiple domains of parental influence on adolescent drinking; including parents' own drinking behaviors, as well as the practices they employ to socialize their children. Despite this prevalence of findings, whether and how these distinct associations are related to one another is still not entirely clear. Methods: The present study used data from 4,731 adolescents and their parents to test the nature of associations between (a) parents' frequencies of alcohol use and…
Safety of primary anastomosis following emergency left sided colorectal resection: an international, multi-centre prospective audit
2018
Introduction: Some evidence suggests that primary anastomosis following left sided colorectal resection in the emergency setting may be safe in selected patients, and confer favourable outcomes to permanent enterostomy. The aim of this study was to compare the major postoperative complication rate in patients undergoing end stoma vs primary anastomosis following emergency left sided colorectal resection. Methods: A pre-planned analysis of the European Society of Coloproctology 2017 audit. Adult patients (> 16 years) who underwent emergency (unplanned, within 24 h of hospital admission) left sided colonic or rectal resection were included. The primary endpoint was the 30-day major complic…
Total polyphenol excretion and blood pressure in subjects at high cardiovascular risk.
2011
Background and aims Dietary factors are critical for the prevention and treatment of hypertension, but data on the effects of specific nutrients on blood pressure (BP) are scarce. The aim of this study was to assess the relationship between total polyphenol excretion (TPE) in urine, as an objective measurement of total polyphenol intake and BP in an elderly population at high cardiovascular risk. Methods and results Cross-sectional substudy of 589 high-risk participants entering in the PREDIMED trial. BP was measured and TPE was determined in urine by Folin–Ciocalteu assay. A significant positive association was observed between TPE in urine and daily intake of fruit and vegetables (F&V), c…
Dietary Inflammatory Index and Incidence of Cardiovascular Disease in the PREDIMED Study
2015
Previous studies have reported an association between a more pro-inflammatory diet profile and various chronic metabolic diseases. The Dietary Inflammatory Index (DII) was used to assess the inflammatory potential of nutrients and foods in the context of a dietary pattern. We prospectively examined the association between the DII and the incidence of cardiovascular disease (CVD: myocardial infarction, stroke or cardiovascular death) in the PREDIMED (Prevención con Dieta Mediterránea) study including 7216 high-risk participants. The DII was computed based on a validated 137-item food frequency questionnaire. Multivariate-adjusted hazard ratios (HR) and 95% confidence intervals of CVD risk we…
A metabolomics-driven approach to predict cocoa product consumption by designing a multimetabolite biomarker model in free-living subjects from the P…
2014
Scope The aim of the current study was to apply an untargeted metabolomics strategy to characterize a model of cocoa intake biomarkers in a free-living population. Methods and results An untargeted HPLC-q-ToF-MS based metabolomics approach was applied to human urine from 32 consumers of cocoa or derived products (CC) and 32 matched control subjects with no consumption of cocoa products (NC). The multivariate statistical analysis (OSC-PLS-DA) showed clear differences between CC and NC groups. The discriminant biomarkers identified were mainly related to the metabolic pathways of theobromine and polyphenols, as well as to cocoa processing. Consumption of cocoa products was also associated wit…
Time to blood culture positivity: An independent predictor of infective endocarditis and mortality in patients with Staphylococcus aureus bacteraemia
2019
International audience; Objectives - Time to blood culture positivity (TTP), a routinely available parameter in automated blood culture systems, may be a proxy for infectious burden in patients with bloodstream infections. We aimed to study the association between TTP and infective endocarditis (IE), or death, in patients with Staphylococcus aureus bacteraemia. Methods - VIRSTA is a multicenter prospective cohort study that included all adult patients with S. aureus bacteraemia in eight university hospitals in France (2009-2011). We analyzed data from four centers which collected data on TTP. Regression models were used to study the association between TTP and definite IE (Duke-Li criteria)…
