    International audiencePeer Instruction (PI) is an instructional strategy for engaging students during class through a structured questioning process that improves the learning of the concepts of fundamental sciences. Although all students are supposedly engaged in discussions with their peers during Peer Instruction, the learning gains generally remain at a medium level, suggesting a lack of participation of certain students who do not benefit from social interactions. The present study examined whether the Stepladder technique might optimize the Peer Instruction method and increase learning gains. With this technique, students enter a group sequentially, forcing every group member to participate in discussions. Eighty-four chemistry students were asked to answer easy and difficult multiple-choice questions before and after being randomly assigned to one of three instructional conditions during a chromatography lesson (Classic PI vs. Stepladder PI vs. Individual Instruction without any discussion with peers). As predicted, results showed that learning gains were greatest in the Stepladder PI group, and that this effect was mainly observed for difficult questions. Results also revealed higher perceived satisfaction when students had to discuss the questions with their peers than when they were not given this possibility. By extending the Stepladder technique to higher education, these findings offer a step forward in the Peer Instruction literature, showing how it can enhance learning gains

    International audienceBackground: The reduction of cardiovascular events with icosapent ethyl-intervention trial (REDUCE-IT) trial revealed robust atherosclerotic cardiovascular risk reduction with a strategy comprising high-dose omega-3 icosapent ethyl vs placebo in statin-treated patients with elevated triglycerides and controlled low-density lipoprotein cholesterol (LDL-C).Hypothesis: Are the results of the REDUCE-IT trial applicable to the French registry on acute ST-elevation and non-ST-elevation myocardial infarction (FAST-MI) population?Methods: Data were extracted from the FAST-MI 2010 and 2015 registries. We applied the REDUCE-IT enrolment criteria (triglycerides 150-500 mg/dL and LDL-C 40-100 mg/dL on statins) to the FAST-MI population in patients aged ≥45 years who had detailed lipid values postacute hospitalization, focusing on their clinical profile and cardiovascular prognosis.Results: Of the 3789 FAST-MI patients with a full lipid profile (median 11.1 [IQR 7.6-17.4] months after hospitalization for myocardial infarction), 472 (12.5%; 95% CI 11.4-13.5) met the eligibility criteria for REDUCE-IT (REDUCE-IT-like group). The cardiovascular event rate (all-cause death, nonfatal myocardial infarction, nonfatal stroke) was 36.7 (95% CI 27.8-48.6) per 1000 person-years for the REDUCE-IT-like group, which compares with the 36.9 (95% CI 26.1-51.5) per 1000 person-years (cardiovascular death, nonfatal myocardial infarction, nonfatal stroke) reported in the REDUCE-IT trial. The residual cardiovascular risk related to elevated triglycerides in the REDUCE-IT-like group was similar to the risk in the REDUCE-IT trial. Conclusions: If the results of REDUCE-IT are applied to patients hospitalized for a myocardial infarction in France, 12.5% of these patients could benefit from a strategyof high-dose omega-3 icosapent ethyl on top of contemporary therapy including statins to improve their clinical outcomes

    International audienceBackground: The COMPASS trial assessed the impact of adding low dose rivaroxaban to aspirin in selected patients (pts). After an acute myocardial infarction (MI), when dual antiplatelet treatment is no longer needed, patients might be eligible for aspirin/rivaroxaban co-therapy. The characteristics and risks of such a population are unclear.Methods: Data were extracted from the FAST-MI 2005, 2010 and 2015 nationwide French registries. Characteristics and long-term mortality were compared according to COMPASS eligibility and between registry and trial populations.Results: Among 9954 patients alive and free of events at one year, 4402 (44%) were classified as COMPASS-Like (i.e. meeting COMPASS inclusion and without exclusion criteria), 1720 (17%) COMPASS-Excluded (i.e. meeting any exclusion criterion) and 3832 (39%) Non-COMPASS (i.e. meeting neither COMPASS inclusion nor exclusion criteria). COMPASS-Like patients were at higher risk and had higher 5-year mortality compared with Non-COMPASS patients. COMPASS-Excluded patients had the highest mortality. COMPASS enrichment criteria defined a population at increased risk of death: eligible pts. had 40% higher 5-year adjusted mortality (Hazard Ratio = 1.40 [1.15; 1.70]), while excluded pts. had 57% higher risk (Hazard Ratio = 1.57 [1.25; 1.97]). Patients meeting the COMPASS criteria one year after MI differed from those included in the randomized trial.Conclusions: Based on the population included in the French FAST-MI registries, enrichment criteria used in COMPASS defined a population representing 44% of the overall population of MI patients surviving to one year, and these patients are at high risk of 5-year mortality. They were at higher risk compared to chronic stable vascular patients enrolled in the trial

    International audienceIntroduction: Patients with established coronary artery disease (CAD) are at very high risk for cardiovascular events.Methods: The DAUSSET study is a national, multicenter, non-interventional study that included very high-risk CAD patients followed by French cardiologists. It aimed to describe real-life clinical practices for low-density lipoprotein (LDL) cholesterol control in the secondary prevention of CAD.Results: A total of 912 patients (mean age, 65.4 years; men, 76.1%; myocardial infarction, 69.4%; first episode, 80.1%) were analyzed. The LDL cholesterol goal was 70 mg/dL in most cases (84.9%). The LDL cholesterol goal <70 mg/dL was achieved in 41.7% of patients. Of the 894 (98.0%) patients who received lipid-lowering therapy, 81.2% had been treated more intensively after the cardiac event, 27.0% had been treated less intensively and 13.1% had been maintained. Participating cardiologists were very satisfied or satisfied with treatment response in 72.6% of patients. Moderate satisfaction or dissatisfaction with lipid-lowering therapy was related to not achieving objectives (100%), treatment inefficacy (53.7%), treatment intolerance (23.4%) and poor adherence (12.3%).Conclusion: These real-world results show that lipid control in very high-risk patients remains insufficient. More than half of the patients did not achieve the LDL cholesterol goal. Prevention of cardiovascular events in these very high-risk patients could be further improved by better education and more intensive lipid-lowering therapy

    International audienceIn the PREVENIR-5 study, artificial neural networks (NN) were applied to a large sample of patients with recent first acute coronary syndrome (ACS) to identify determinants of persistence of evidence-based cardiovascular medications (EBCM: antithrombotic + beta-blocker + statin + angiotensin converting enzyme inhibitor-ACEI and/or angiotensin-II receptor blocker-ARB). From October 2006 to April 2007, 1,811 general practitioners recruited 4,850 patients with a mean time of ACS occurrence of 24 months. Patient profile for EBCM persistence was determined using automatic rule generation from NN. The prediction accuracy of NN was compared with that of logistic regression (LR) using Area Under Receiver-Operating Characteristics-AUROC. At hospital discharge, EBCM was prescribed to 2,132 patients (44%). EBCM persistence rate, 24 months after ACS, was 86.7%. EBCM persistence profile combined overweight, hypercholesterolemia, no coronary artery bypass grafting and low educational level (Positive Predictive Value = 0.958). AUROC curves showed better predictive accuracy for NN compared to LR models

    Objective. To investigate perceived health status and prevalence of drug use, tobacco smoking, consumption of alcohol and illicit substances in a student population. Methods. Data were obtained from an anonymous questionnaire distributed to first-year students of the Toulouse University. Collected data concerned socio-demographic characteristics, perceived health status, and consumption of tobacco, alcohol, illicit substances and drugs. Results. Fifty seven percent of the 3 561 responders declared to have taken at least one drug during the week preceding the questionnaire. Most commonly Anatomical, Therapeutic and Chemical (ATC) classes used were genito-urinary system and sex hormones (29.6%), nervous system (16.4%) and alimentary tract and metabolism (14.1%). Twenty three percent of students were smokers. Differences according to health perception were found for tobacco and cannabis consumption. Anxiety was significantly more prevalent among students reporting that they did not consume alcohol (p<0.05). Conclusion. More than half of students use drugs. Other consumptions (tobacco, alcohol and illicit substances) are related with perceived health status

    Do randomized clinical trial selection criteria reflect levels of risk as observed in a general population of acute myocardial infarction survivors? The PEGASUS trial in the light of the FAST-MI 2005 registry

    IF 4.638International audienceBackground: Few clinical trials have focused on populations with a history of distant myocardial infarction (MI). The PEGASUS trial assessed the impact of dual antiplatelet therapy in such patients, selected by enrichment criteria of high cardiovascular risk. Whether the PEGASUS population reflects the risk of a broader post-MI population is questionable. We analyzed whether 4-year mortality of a routine-practice population would differ according to the inclusion and exclusion criteria used in PEGASUS.Methods: FAST-MI is a nationwide French registry recruiting acute MI patients in November 2005; 2490 patients alive and without recurrent MI at one year were classified into three groups: Group 1 ("PEGASUS-like" population; n = 1395; 56%), Group 2 (population having = 1 exclusion criterion for the trial; n = 677; 27%), and group 3 (population meeting neither the PEGASUS inclusion nor exclusion criteria; n = 418, 17%).Results: Group 1 patients were older than Group 3 patients, with higher GRACE scores, more comorbidity, and less STEMI, but were younger than the PEGASUS trial population. Enrichment criteria successfully defined a population at higher risk: 4-year survival 83% in Group 1, 97% in Group 2, and 68% in Group 3 (P < 0.001). Among risk-enrichment criteria, age alone was highly discriminant: in PEGASUS-like patients, survival was 78% in those = 65 versus 94% in those <65 years.Conclusions: Enrichment criteria used in PEGAGUS succeed in defining a population at increased risk in patients with prior MI, age being the most discriminant factor. The trial population, however, was notably younger and more masculine than the corresponding real-life population in France. (C) 2016 Elsevier Ireland Ltd. All rights reserved

    IF 3.398International audienceThe 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 MI. Overall, patients with a history of atherosclerotic disease (or MI) were older compared with patients without known cardiovascular disease (71 ± 13 vs 63 ± 14 years) and had higher cardiovascular risk profiles and co-morbidities. Using fully adjusted Cox multivariate analysis, previous manifestations of atherosclerotic disease were associated with higher 3-year mortality (hazard ratio 1.80, 95% confidence interval 1.40 to 2.31; p <0.001) as history of previous MI alone (hazard ratio 1.32, 95% confidence interval 1.00 to 1.73; p = 0.048). Similar results were found in patients discharged alive. In conclusion, previous cardiovascular atherosclerotic disease represents 1/3 of patients with AMI and are strongly associated with worse long-term clinical outcomes. Intensive follow-up and therapy should be encouraged in this high-risk population

    International audienceObjective - In acute coronary syndromes, switching between thienopyridines is frequent. The aims of the study were to assess the association between switching practices and quality of care. Methods - Registry study performed in 213 French public university, public non-academic and private hospitals. All consecutive patients admitted for acute myocardial infarction (MI; 60 kg, no history of stroke, cardiac arrest, anaemia or renal dysfunction. In patients with a switch, eligibility for prasugrel was >82% and appropriate use of a switch was 86% from clopidogrel to prasugrel and 20% from prasugrel to clopidogrel. Quality indicators scored higher in the group with a switch and also in centres where the switch rate was higher. Conclusions - As applied in the French Registry on Acute ST-elevation and non ST-elevation Myocardial Infarction (FAST-MI) registry, switching from one P2Y12 inhibitor to another led to a more appropriate prescription and was associated with higher scores on indicators of quality of care

    An innovative lipid-lowering approach to enhance attainment of low-density lipoprotein cholesterol goals

    No full text
    International audienceAims:To improve attainment of LDL-cholesterol (LDL-c) targets, an expert group proposed an algorithm for lipid-lowering therapy during hospitalization for acute coronary syndrome and during follow-up. We aimed to assess adherence to this algorithm, and evaluate its impact on LDL-c levels and on attainment of therapeutic LDL-c targets in a population of post-acute coronary syndrome patients. Methods and results: Prospective, observational study including patients admitted for acute coronary syndrome between February 2017 and September 2018. Patients admitted without statins or ezetimibe were considered ‘naïve’. Baseline LDL-c was admission LDL-c in naïve patients, and for those taking lipid-lowering therapy at admission, baseline LDL-c was back-calculated. In line with the most recent guidelines, the target was a &gt;50% reduction in naïve LDL-c and &lt;55 mg/dL. In total, 270 patients were analysed, mean age 67 ± 12 years, 78% men, 26% diabetic. At admission, 175 (65%) were naïve, 95 (35%) had previous lipid-lowering therapy, of which 13 (5%) statin+ezetimibe. Average LDL-c at admission was 120 ± 47 mg/dL (136 ± 44 mg/dL in naïve, 91 ± 39 mg/dL in pretreated patients). Discharge prescription was in compliance with the algorithm in 204 (76%) patients. Average LDL-c at two months was 57 ± 28 mg/dL; it was &lt;55 mg/dL in 135 (50%), and 178 (66%) achieved a &gt;50% reduction. Overall, 125/270 (46%) achieved the LDL-c goal. The reduction in LDL-c observed at two months persisted at five months. Conclusion: Prescription of high-intensity statins, associated with ezetimibe where applicable, achieves LDL-c levels &lt;55 mg/dL in 50% of patients at two months, and attains therapeutic goals defined by the European Society of Cardiology in 46% of cases
