Abstract
Introduction The health context with COVID-19 pandemic has led to fast development of many vaccines against the SarS-Cov-2 virus. Four of them are currently available in France and contain polyethylene glycol (PEG) or polysorbate 80 as excipients, already described as causing anaphylaxis. French recommendations have been suggested by allergology authorities and proposed a course of action in the event of a suspected allergy to these vaccines. Thus, allergies to excipients were the only contraindication to COVID-19 vaccination. Our main objective was to determine the impact of these allergology vaccine recommendations on the management of these patients. Our secondary objective was to determine prevalence of true allergies to these vaccines. Materials and methods We conducted a unicentric descriptive retrospective study with all patients over 18 years of age referred for an allergological opinion before or after an injection of one of the anti-COVID-19 vaccines. Nineteen patients were classified into different interest groups, based on french recommendations. Results The vast majority of patients did not require a pre-vaccination allergological assessment. Indeed, only 25 patients received skin tests prior to vaccination. The rest of patients were able to be vaccinated without allergological assessment. Patients not vaccinated due to allergy to excipients represent less than 1% of the population (n = 3/320). Conclusion French recommendations made it possible to vaccinate the vast majority of patients included in our study. Allergy to PEG, polysorbate or their derivatives, the only contraindication to anti-COVID vaccination, according to the recommendations of February 2021, remains rare. Today, several authors propose tolerance inductions allowing the vaccination of patients allergic to PEGs or their derivatives with good tolerance.

Abstract
Abstract
Background
Recent advances in drug eluting stents (DES) design have significantly decreased the rates of in-stent restenosis (ISR). Nonetheless, ISR remains a major problem, affecting 5–10% of patients undergoing percutaneous coronary intervention (PCI). Furthermore, PCI for ISR is often a poor prognostic factor for outcomes after the procedure. Historically, obese patients tended to have better outcomes when undergoing PCI, however it is unclear if this trend continues for the same population undergoing PCI for ISR.
Purpose
Investigate the outcomes of patients undergoing PCI for ISR in the overweight and normal weight population.
Methods
All patients undergoing PCI with DES implantation at a tertiary care center from January 2012 to December 2019 were included. Normal weight was defined as a body mass index (BMI) greater than or equal to 18.5 kg/m2 and less than 25 kg/m2, while overweight was defined as a BMI greater than or equal to 25 kg/m2. Patients with BMI <18.5 kg/m2, underwent PCI for acute myocardial infarction (MI), or received a bare metal stent (BMS) were excluded. The primary outcome was major events (MACE), a composite of all-cause mortality, myocardial infarction (MI), and target vessel revascularization (TVR) up to one year after PCI. Secondary outcomes included individual components of the primary endpoint.
Results
Out of 16,234 patients with available data on BMI, 12,444 (76.7%) were overweight and 3,790 (23.3%) were normal weight. Among overweight patients, 2,879 (23.1%) underwent PCI for ISR versus 815 (21.5%) of normal weight patients. Regardless of BMI status, patients undergoing PCI for ISR had higher rates of co-morbidities such as hypertension, hyperlipidemia, and diabetes mellitus than non-ISR counterparts. At one year post PCI, both overweight and normal weight patients undergoing PCI for ISR had increased risk of MACE (overweight: 18.4% vs. 6.7%; HR 2.83; 95% CI 2.50–3.20; normal weight: 18.8% vs. 7.8%, HR 2.43, 95% CI 1.95–3.04) when compared to non-ISR counterparts, mostly driven by TVR (overweight: 16% vs. 4.6%; HR 3.58; 95% CI 3.11–4.13; normal weight: 15.2% vs. 4.1%; HR 3.69; 95% CI 2.80–4.86). However, only overweight patients undergoing PCI for ISR had higher risk of all cause mortality (2.2% vs. 1.5%; HR 1.42; 95% CI 1.03–1.95) and MI (3.0% vs. 1.3%, HR 2.22; 95% CI 1.64–2.99) when compared to non-ISR counterparts (Figure 1).
Conclusions
PCI for ISR was associated with increased risk of MACE, irrespective of body weight. The risks of all-cause mortality and MI in ISR vs non-ISR patients only reached statistical significance in overweight patients.

Abstract
Abstract
Background
Potent P2Y12 inhibitors are recommended on top of aspirin in patients presenting with acute coronary syndrome (ACS). However, guideline recommendations suggest that the optimal antithrombotic strategy should be tailored based on patients thrombotic and hemorrhagic risk profile.
Purpose
It is poorly investigated if the benefits derived from potent P2Y12 inhibition in patients with ACS depend on the individual thrombotic risk profile. Our aim was to evaluate if the benefits associated with prasugrel vs. clopidogrel in patients with ACS undergoing percutaneous coronary intervention (PCI) are similar in case of different thrombotic risk profiles.
Methods
PROMETHEUS was a multicenter observational study comparing prasugrel vs. clopidogrel in ACS patients undergoing PCI. According to the 2020 ESC guidelines for non-ST elevation-ACS, patients are defined at high thrombotic risk if presenting with a clinical (diabetes mellitus requiring medication, history of recurrent myocardial infarction [MI], multivessel coronary artery disease [CAD], polyvascular [coronary and peripheral] disease, premature (<45 years) CAD, and chronic kidney disease [estimated glomerular filtration rate <60 ml/min/1.73m2]) and procedural (≥3 stents implanted, ≥3 lesions treated, total stent length >60 mm, complex revascularization [left main PCI, bifurcation or chronic total occlusion]) risk features. The primary endpoint was major adverse cardiac events (MACE), a composite of death, MI, stroke or unplanned revascularization. Hazard ratio (HR) and 95% confidence intervals (CI) were calculated using propensity-stratified analysis to assess the effect of prasugrel vs. clopidogrel and with multivariable Cox regression to evaluate the impact of thrombotic risk.
Results
Among 16065 patients, 4293 were defined at high thrombotic risk and 11772 at low-to-moderate thrombotic risk. Patients treated with prasugrel had less comorbidities and risk factors than those treated with clopidogrel, both in the high and low-to-moderate thrombotic risk strata. Patients at high thrombotic risk had higher rates of both ischemic and bleeding events at 90 days and at 1 year. Patients treated with prasugrel had a lower adjusted risk of MACE at 1 year (HR 0.86, 95% CI 0.77–0.96), with no significant interaction between effect estimates and thrombotic risk. However, after stratifying the study population by the number of risk factors, there was a significant interaction for a greater reduction in MACE with prasugrel in patients with ≤1 thrombotic risk factor. Conversely, there were no differences in major bleeding among patients treated with prasugrel and clopidogrel.
Conclusions
Patients with ACS at high thrombotic risk who undergo PCI are at increased risk of adverse events. Prasugrel, although mainly reserved to patients with lower burden of comorbidities, reduced the risk of ischemic events both in patients at high and low-to-moderate thrombotic risk as compared with clopidogrel.

Abstract
Abstract
Background
Dual antiplatelet therapy (DAPT) with a potent P2Y12 inhibitor is recommended in patients with acute coronary syndrome (ACS) and should be tailored according to ischemic and bleeding risks, which are highest in the acute phase, and gradually attenuate overtime. De-escalation strategies of DAPT aim to optimize this balance of risks.
Purpose
We compared guided or unguided DAPT de-escalation strategies from potent P2Y12 inhibitors to either clopidogrel or lower doses of potent P2Y12 inhibitors versus standard DAPT with potent P2Y12 inhibitors among patients with ACS.
Methods
PubMed, Google Scholar and Cochrane Central Register of Controlled Trials were searched from inception till March 10th 2021. 1633 records were screened on DAPT de-escalation strategies after ACS for inclusion. Aspirin monotherapy and non-randomized trials were excluded.
The primary endpoint was BARC ≥2 bleeding. Other endpoints included MACE (defined according to the definitions reported in the original study protocols), all-cause death, cardiovascular death, myocardial infarction, stent thrombosis, and stroke. Hazard ratios (HRs) and 95% CIs were used as metric of choice for treatment effects with random-effects models. Heterogeneity was assessed with the I2 index. We assessed the interaction between de-escalation strategy (guided vs. unguided) and treatment with a random-effects meta-regression analysis with the empirical Bayes method. This study has been submitted to PROSPERO for registration.
Preliminary findings
Four randomised trials and a total of 8,082 patients randomly allocated to a de-escalation strategy (genetic guided to clopidogrel, n=1,242; platelet function guided to clopidogrel, n=1,304; unguided to clopidogrel (n=323); unguided to lower dose, n=1,170) or standard DAPT (n=4,043) were included in our analysis. De-escalation strategy had a reduction in BARC ≥2 bleeding (HR 0.57, 95% CI 0.37–0.89; I2=81%). MACE (HR 0.79, 95% CI 0.62–1.02; I2=0%), all-cause death (HR 0.89, 95% CI 0.58–1.36), cardiovascular death (HR 0.63, 95% CI 0.36–1.10; I2=0%), myocardial infarction (HR 0.81, 95% CI 0.56–1.17; I2=0%), stent thrombosis (HR 0.57, 95% CI 0.19–1.74; I2=0%) and stroke (HR 0.73, 95% CI 0.39–1.35; I2=0%) did not differ between patients with a de-escalation strategy and those without. Meta-regression analysis did not show any significant interaction between de-escalation method (guided vs. unguided) and treatment effects, except for BARC ≥2 bleeding (P interaction = 0.070), suggesting a greater reduction with unguided de-escalation.
Conclusion
A de-escalation strategy of DAPT after ACS was associated with a lower number of clinically relevant bleeding events, mostly in patients who underwent unguided de-escalation, while no association with increased ischemic events was found. However, the observed broad confidence intervals limit the certainty of our findings.

Abstract
Abstract
Background
Sodium-glucose co-transporter 2 (SGLT-2) inhibitors emerged as a new groundbreaking therapy for patients with heart failure. Recent evidence showed significant benefits in patients with heart failure with reduced ejection fraction (HFrEF), regardless of diabetic status. Whether these medications also improve outcomes in patients without a history of heart failure or with heart failure with preserved ejection fraction (HFpEF) remains unknown.
Purpose
We sought to perform an updated meta-analysis of randomized controlled trials to evaluate the effects of SGLT-2 inhibitors on cardiovascular (CV) outcomes according to the history and type of heart failure.
Methods
All randomized, placebo-controlled trials of SGLT-2 inhibitors reporting similar CV outcomes were evaluated for inclusion. PubMed was searched from January 1, 2010 to February 1, 2021. Articles were independently reviewed and selected by two reviewers. The primary outcome was the composite of first hospitalization for heart failure and CV death. Secondary outcomes included its single components and all-cause mortality. Pooled hazard ratios (HR) and 95% confidence intervals (CI) were used as effect estimates and calculated with a random-effects model. Heterogeneity was assessed with the I2 index, and random-effects meta-regression was used to assess the interaction between treatment effect and history of heart failure and type of heart failure (HFrEF vs. HFpEF).
Results
Data from eight trials and a total of 56,665 patients (n=31,609 in SGLT-2 group, n=25,056 in placebo group) were included. Five studies enrolled high-risk patients with diabetes mellitus, while 3 studies enrolled patients with symptomatic heart failure. SGLT-2 inhibitors reduced the risk of first hospitalization for heart failure and CV death in patients with (HR 0.75 95% CI 0.70–0.81) and without (HR 0.78 95% CI 0.67–0.90; Figure 1) a history of heart failure. Similarly, patients with (HR 0.85 95% CI 0.78–0.93) or without (HR 0.85 95% CI 0.74–0.98) a history of heart failure treated with SGLT-2 inhibitors had a significant reduction in all-cause mortality. SGLT-2 inhibitors reduced the risk of CV death regardless of the history of heart failure, although the reduction was border-line statistically significant in patients without a history of heart failure (HR 0.81 95% CI 0.66–1.00; Figure 2). All subgroup interaction testing between patients with and without a history of heart failure was negative for all the above endpoints. Among patients with HFpEF, SGLT-2 inhibitors were associated with a nonsignificant trend towards reduced risk of the primary outcome (HR 0.80 95% CI 0.63–1.02).
Conclusions
SGLT-2 inhibitors significantly improve CV outcomes in patients with or without history of heart failure, and this effect seems to be consistent among those with HFrEF and HFpEF.

Abstract
Abstract
Background
Reduced left ventricular ejection fraction (LVEF) is associated with increased risk of adverse events among patients undergoing percutaneous coronary intervention (PCI). Due to under-enrollment of females in randomized trials, there is limited data on the impact of LVEF on post-PCI outcomes in female patients.
Purpose
To evaluate the impact of varying degrees of LVEF impairment on 3-year outcomes in female patients undergoing PCI with drug-eluting stents (DES).
Methods
We pooled patient-level data of female patients from 26 randomized trials of coronary stents. The study population was stratified into three groups according to the 2016 European Society of Cardiology Heart Failure guidelines: LVEF ≥50% (normal), LVEF 40–49% (mid-range), and LVEF <40% (reduced). The primary outcome was major adverse cardiac events (MACE), a composite of cardiac death, myocardial infarction (MI), or stent thrombosis (ST) at 3-year follow-up. The Kaplan-Meier method was used for time-to-event analyses, with comparative risks being assessed using Cox regression.
Results
Out of 5672 female patients with available LVEF values at baseline, 4427 (78.1%) had normal LVEF, 602 (10.6%) had mid-range LVEF, and 643 (11.3%) had reduced LVEF. Patients with reduced LVEF were older and had a higher prevalence of smoking, prior MI, and multi-vessel disease. There was a stepwise increase in 3-year event rates moving from normal, to mid-range and reduced LVEF (Figure 1). After multivariable adjustment, hazard ratio (HR) for MACE was 1.45 (95% CI: 1.10–1.92) in patients with mid-range LVEF and 2.43 (95% CI: 1.84–3.22) in patients with reduced LVEF (trend p-value <0.0001). The risk of ST was more than doubled in both mid-range LVEF (HR 2.30, 95% CI: 1.30–4.06, p=0.004) and reduced LVEF patients (HR 2.18, 95% CI: 1.11–4.28, p=0.02), as compared with normal LVEF.
Conclusion
The presence of an even mild degree of LVEF impairment confers an increased risk of ischemic events, including ST, among females undergoing PCI with DES.

Abstract
Abstract
Introduction
Patients presenting for percutaneous coronary intervention (PCI) with acute coronary syndromes (ACS) often have overlapping bleeding and ischaemic risk factors that offset the long-term success of PCI and limit the post stenting therapeutic options. Aiming at improving outcomes following PCI, the Academic Research Consortium (ARC) recently published a set of major and minor criteria that identify, a priori, patients at high bleeding risk (HBR). Indeed, knowledge of these risk factors will help in optimization of pre-procedural therapy and minimization of post intervention complications. Nonetheless, the actual prevalence of these criteria among patients undergoing PCI for ACS is not well known.
Purpose
To determine the intersection and distribution of ARC-HBR major and minor criteria in a real-world ACS population presenting for PCI.
Methods
In this analysis, we included all patients who presented with ACS to a high-volume PCI centre from 2012 to 2017 and underwent PCI with 2nd generation drug-eluting stent (DES) implantation. Patients were then classified as HBR if they met ≥1 major or ≥2 minor criteria according to the ARC-HBR definition. Baseline clinical and procedural characteristics were extracted from each patient electronic health records. The most common exclusive intersections of ARC-HBR major and minor criteria were quantitatively visualized using an Upset Plot.
Results
Only 44.6% (n=2,717) of ACS patients (n=6,097) fulfilled the ARC-HBR definition. There were significant differences in baseline clinical characteristics between HBR and non-HBR groups: age (71.4±11.5 vs. 60.9±10.3 years, p<0.001), females (40.7% vs. 25.5%, p<0.001), cerebrovascular disease (19.5% vs. 3.9%, p<0.001), and diabetes (55.4% vs. 42.1%, p<0.001). The prevalence of active smoking, a major risk factor for bleeding, was higher in the non-HBR group (20.6% vs. 9.9%, p<0.001). The most frequent major and minor criteria were severe anemia (n=1,072) and age ≥75 (n=1,264), respectively. The top five criteria intersections were: severe anemia (n=215), age ≥75 and moderate chronic kidney disease (CKD) (n=145); moderate CKD and mild anemia (n=142); age ≥75 and mild anemia (n=140); age ≥75, moderate CKD, and mild anemia (n=130) (Figure 1).
Conclusion
Among patients who have undergone PCI for ACS, a significant proportion of individuals fulfilled the ARC-HBR definition. Severe anemia was the most prevalent major criteria. Different combinations of minor criteria, mainly age ≥75, moderate CKD and mild anemia, represented the most common intersections.

Abstract
Abstract
Background
The Academic Research Consortium (ARC) has recently published a consensus-based definition to identify patients at high bleeding risk (HBR), reflected by a BARC 3 or 5 bleeding rate of ≥4% at 1 year after percutaneous coronary intervention (PCI). The HBR criteria included in the definition are divided into minor and major categories, with patients deemed to be at HBR if they fulfill at least one major or two minor criteria. As a result, patients who present with only one minor criterion are categorized as non-HBR.
Purpose
To compare the differences in baseline characteristics and 1-year bleeding and ischaemic outcomes between non-HBR patients undergoing PCI that present with only one minor HBR criterion versus those that do not fulfill any HBR criteria.
Methods
The study population consisted of all consecutive patients who underwent PCI with stent implantation in a single high-volume centre from January 2014 to December 2017. Patients were classified as non-HBR if they did not fulfill at least one major or two minor ARC-HBR criteria. The outcomes of interest were major bleeding (composite of peri-procedural and post-discharge bleeding), all-cause death, and myocardial infarction (MI) at 1 year. The Kaplan-Meier method was used for time-to-event analyses, with comparative risks being assessed using Cox regression.
Results
Of the 9,623 patients included in the analysis, 5,345 were classified as non-HBR. Within the non-HBR patients, 2,078 (38.9%) presented with only one minor HBR criterion and 3,267 (61.1%) presented with no HBR criteria. Non-HBR patients with one minor criterion were more often female, significantly older, with a higher burden of comorbidities such as diabetes mellitus, hypertension and hyperlipidaemia, and more likely to have multivessel disease as well as a history of prior MI and revascularisation, while non-HBR patients with no criteria were more likely to be smokers and have a higher BMI. Distribution of the minor HBR criteria within the group presenting with one minor criterion are illustrated in the figure. Non-HBR patients with only one minor criterion had a numerically higher rate of major bleeding compared to non-HBR patients with no criteria (3.6% vs. 2.9%, p=0.09). While the rate of all-cause death was significantly higher in the group with only one minor criterion (1.2% vs. 0.4%, p=0.004), there was no difference in the rate of MI between the two groups (2.1% vs. 1.9%, p=0.83). Hazard ratios comparing the two groups are presented in the figure.
Conclusions
Non-HBR patients presenting with only one minor criterion had a numerically higher rate of post-PCI bleeding and significantly higher mortality compared to those without any criteria. Nonetheless, the major bleeding rates of both groups at 1 year were less than the 4% cutoff to qualify as HBR according to the ARC definition, thereby supporting their inclusion as “minor” criteria in the recent ARC-HBR definition.

Abstract
Abstract
Background/Introduction
Low levels of high-density lipoprotein (HDL) have been associated with adverse cardiovascular events in multiple epidemiological studies. Evidence regarding the role of HDL in males and females with established coronary artery disease undergoing percutaneous coronary intervention (PCI) with drug eluting stents (DES) is scarce.
Purpose
We sought to investigate the impact of low HDL levels on 1-year cardiovascular outcomes in males and females undergoing PCI with DES.
Methods
We screened all patients undergoing PCI in our center from 2012 to 2017. Exclusion criteria were: unavailable baseline HDL measurement, age <18 years, presentation with ST-segment elevation myocardial infarction (MI) or shock, coexisting neoplastic disease and treatment without a stent or with a bare metal stent. The final population was divided by gender and further stratified to the high or low HDL group according to baseline HDL levels. Cut-offs were 40mg/dL in males and 50mg/dL in females, per the most recent ACC/AHA guideline recommendations. The primary endpoint of the analysis was major adverse cardiovascular events (MACE) at 1 year, defined as death, MI or target vessel revascularization (TVR). To account for potential clinical and anatomical confounders the outcomes were also adjusted for age, Caucasian ethnicity, hypertension, diabetes mellitus (DM), body mass index, smoking, prior MI, multi-vessel disease and type B2/C lesions.
Results
Out of the 10,843 patients included, 7,718 (71.2%) were male and 3,125 (28.8%) were female. Low HDL was noted in 58.5% of males and 63.8% of females. Patients with low HDL were younger and had a higher prevalence of DM, prior MI, smoking and multi-vessel disease. When comparing low to high HDL groups in terms of 1-year MACE a borderline significant difference was shown in males (7.4% vs. 6.0%; p-value=0.08) but not in females (7.7% vs 8.1%; p-value=0.90) [Panel A]. The numerically higher incidence of MACE in males with low HDL was primarily driven by TVR (5.4% vs 3.7%; p-value=0.005) while the rates of Death (1.4% vs. 1.3%; p=0.96) and MI (2.0% vs. 1.8%; p-value=0.89) were similar between the two groups. After adjustment the male low HDL subgroup remained at a higher risk for 1-year TVR but not 1-year MACE compared to the male high HDL subgroup [Panel B]. No difference for any individual component of MACE was shown between low and high HDL subgroups in females [Panel C].
Conclusion(s)
High HDL levels were associated with a lower incidence of TVR and borderline reduction of MACE in male but not female patients undergoing PCI with DES. No difference was demonstrated in terms of death or MI between the high and low HDL subgroups at 1-year follow-up.

Abstract
Abstract
Introduction
Current clinical guidelines recommend prolonged dual antiplatelet therapy (DAPT) following percutaneous coronary intervention (PCI) in patients presenting with acute coronary syndromes (ACS). However, an extended DAPT duration in high-bleeding risk (HBR) patients amplifies the risk of post procedural complications. Hence, clinicians often face the dilemma of prolonging DAPT duration to prevent recurrent ischaemic events at the expense of increasing the incidence of bleeding in high-risk patients. The actual incidence of ischaemic and bleeding events in this particular population is not well elucidated.
Purpose
To evaluate one-year ischemic and bleeding outcomes following PCI for ACS in a real-world HBR population as defined by the Academic Research Consortium (ARC) consensus document.
Methods
We included all patients who presented with ACS to a high-volume single PCI centre from 2012 to 2017 and underwent PCI with 2nd generation drug-eluting stent implantation. Patients were classified as HBR if they met ≥1 major or ≥2 minor criteria according to the recent ARC-HBR consensus. The outcomes of interest were major adverse cardiovascular events (MACE), a composite of all-cause death, myocardial infarction (MI), and target lesion revascularization (TLR), and major bleeding events, including both peri-procedural and post-discharge bleeding. All outcomes were assessed at 1-year follow-up. The Kaplan-Meier method was used for time-to-event analyses.
Results
Out of 6,097 ACS patients included in this analysis, 2,717 (44.6%) fulfilled the ARC-HBR definition. Compared to non-HBR group, HBR patients were more frequently female, older, more likely to have cardiovascular risk factors (e.g., diabetes, hypertension, and hyperlipidemia) and complex coronary artery disease (e.g., multi-vessel disease, bifurcation lesions, and calcification). The 1-year incidence of MACE was significantly higher in HBR patients (16.3% vs. 8.1%, HR 2.16, 95% CI [1.81–2.59], p<0.001) (Figure 1A). This finding was driven by higher rates of all-cause death and MI (Figure 1B). The 1-year incidence of major bleeding was also significantly higher in HBR patients compared to non-HBR (11.1% vs. 3.1%, HR: 3.92, 95% CI 3.10–4.95; p<0.001).
Conclusions
HBR patients undergoing PCI for ACS are not only subject to bleeding complications but are also at an increased risk for ischemic events and all-cause mortality.

Abstract
Abstract
Background
The presence of any benefits associated with radial or femoral access among patients undergoing coronary angiography and percutaneous coronary interventions (PCI) is still debated.
Purpose
Our aim is to provide a comprehensive quantitative appraisal of the effects of access site on the risks of stroke, myocardial infarction, and major bleeding in patients undergoing coronary angiography with or without PCI.
Methods
In January 2020, we searched PubMed, Embase, and meeting abstracts for randomized trials comparing radial versus femoral access for coronary angiography with or without subsequent PCI. Odds ratios (OR) were used as metric of choice for treatment effects with random-effects models. Co-primary efficacy endpoints were stroke and myocardial infarction. Primary safety endpoint was major bleeding. Secondary endpoints were all cause mortality and vascular complications. Heterogeneity was assessed with the I-squared index. This study is registered with PROSPERO.
Results
We identified 31 trials, including 30,414 patients. Risks of stroke (OR 1.11, 95% CI 0.76–1.64, I2=0%) and myocardial infarction (OR 0.90, 95% CI 0.79–1.03, I2=0%) were comparable between radial and femoral access. Radial access was associated with a reduction for the risk of major bleeding as compared to femoral access (OR 0.53, 95% CI 0.42–0.67, I2=3.3%) with a number needed to treat of 92. Findings were consistent regardless clinical features and procedure performed, with the only exception of an increased benefit of the radial access in patients with chronic coronary syndrome (p forinteraction=0.005). The risk for all-cause mortality (OR 0.73, 95% CI 0.61–0.89, I2=0%) and vascular complication (OR 0.32, 95% CI 0.23–0.44, I2=16.7%) was significantly lower in the radial compared to femoral access group.
Conclusions
In patients undergoing coronary angiography with or without PCI, radial compared to femoral access did not reduce the risk of stroke and myocardial infarction, with no impact on the effect estimates of clinical presentation, age, gender, or subsequent PCI. Whereas, radial access is associated with a significant risk reduction of major bleeding as compared to femoral access. The benefit favoring radial access is of important clinical relevance in view of the relatively low number needed to treat to prevent a major bleeding and the significant impact on mortality.

Abstract
Reliable, clinically useful, and globally applicable diagnostic classification of mental disorders is an essential foundation for global mental health. The World Health Organization (WHO) is nearing completion of the 11th revision of the International Classification of Diseases and Related Health Problems (ICD-11). The present study assessed inter-diagnostician reliability of mental disorders accounting for the greatest proportion of global disease burden and the highest levels of service utilization - schizophrenia and other primary psychotic disorders, mood disorders, anxiety and fear-related disorders, and disorders specifically associated with stress - among adult patients presenting for treatment at 28 participating centers in 13 countries. A concurrent joint-rater design was used, focusing specifically on whether two clinicians, relying on the same clinical information, agreed on the diagnosis when separately applying the ICD-11 diagnostic guidelines. A total of 1,806 patients were assessed by 339 clinicians in the local language. Intraclass kappa coefficients for diagnoses weighted by site and study prevalence ranged from 0.45 (dysthymic disorder) to 0.88 (social anxiety disorder) and would be considered moderate to almost perfect for all diagnoses. Overall, the reliability of the ICD-11 diagnostic guidelines was superior to that previously reported for equivalent ICD-10 guidelines. These data provide support for the suitability of the ICD-11 diagnostic guidelines for implementation at a global level. The findings will inform further revision of the ICD-11 diagnostic guidelines prior to their publication and the development of programs to support professional training and implementation of the ICD-11 by WHO member states.

Abstract
Optical elements of soft x-ray beamlines usually have motorized translations and rotations that allow for the fine alignment of the beamline. This is to steer the photon beam at some positions and to correct the focus on slits or on sample. Generally, each degree of freedom of a mirror induces a change of several parameters of the beam. Inversely, several motions are required to actuate on a single optical parameter, keeping the others unchanged. We define optical pseudomotors as combinations of physical motions of the optical elements of a beamline, which allow modifying one optical parameter without affecting the others. We describe a method to obtain analytic relationships between physical motions of mirrors and the corresponding variations of the beam parameters. This method has been implemented and tested at two beamlines at ALBA, where it is used to control the focus of the photon beam and its position independently.

Abstract
The carbohydrate oxidase (COXMn) from Microdochium nivale may well have desired functionalities as a dough and bread improver, similarly to Aspergillus niger glucose oxidase (GOX). COXMn catalyses the oxidation of various monosaccharides as well as maltooligosaccharides for which the best activity is obtained towards the maltooligosaccharides of polymerisation degrees 3 and 4. For the same activity towards glucose under air saturation, we show that COXMn exhibits a similar efficiency towards maltose as GOX towards glucose whatever the oxygen supply. Assays with COXMn show that no competition exists between carbohydrates naturally present in the wheat flour. We show that reaction products (d-glucono-δ-lactone and hydrogen peroxide) and the wheat flour dough component, ferulic acid, have no noticeable specific effect on the COXMn activity. The demonstrated differences in kinetics between COXMn and GOX allow predicting of differences in the functional behaviours of those enzymes during wheat flour dough formation.

Abstract
BACKGROUND There is no data on long-term benefit of once-a-day antiretroviral therapy (ART) with combination of DDI, 3TC and EFV to allow its use in future therapeutic strategies. OBJECTIVES To assess 24-month immuno-virological, adherence, tolerance, and effectiveness of a once-a-day ART with DDI, 3TC and EFV. METHODS A phase 2 open trial including 51 children aged from 30 months to 15 years, monitored a once-a-day regimen for 24 months from 2006 to 2008 in the Departement de Pediatrie du CHUSS, at Bobo-Dioulasso in Burkina Faso. We tested immunological and virological response, adherence, tolerance and resistance of the treatment. RESULTS Children with CD4 >25% at 24 months were 67.4% (33/49) CI 95% [54%, 80%]. The proportion of children with viral plasma RNA <300 cp / ml at 24 months of treatment was 81.6 % (40/49) CI [68.0% 91.2%]. Good adherence was obtained with more than 88% adherence > 95% over the 24 months. Drugs were well tolerated. CONCLUSIONS Given the limited number of antiretroviral drugs available in Africa and the inadequacy of laboratory monitoring in support program, once-a-day treatment and especially the DDI-based combination strategies could be an attractive operational option.

Abstract
This paper presents the methodologies to determine odour in ambient air by field inspection that will be a new European standard. The objective is to characterise the odour in a defined area. Without making a link with potential annoyance due to the presence of odours, the described methods propose the way to characterise an exposed environment. Two approaches are defined in the new standard: the grid method and the plume method. The grid method can be used to determine the exposure to ambient odours in a defined area of study, using direct observation of recognisable odours in the field by human panel members. This method must be applied over a sufficiently long period of time (6 or 12 months) to be representative of the meteorological conditions of that location. The result is the distribution of the frequency of exposure to odours within the assessment area. The plume method can be used to determine the extent of detectable and recognisable odours from a specific source using direct observation in the field by human panel members under specific meteorological conditions.

Abstract
INTRODUCTION Typhoid is a common reason for seeking medical care in general practice in the developing countries, Use of the Widal and Felix test is frequent in this setting. The purpose of this study carried out in private general medicine clinics in Niamey, Niger was to determine the incidence of typhoid and the predictive value of positive and negative results of the Widal test. MATERIAL AND METHOD We used low published values of sensitivity (67.9%) and specificity (93.8%). Estimation of the incidence of typhoid was based on reports made to the national health information system of Niger by 3 private clinics in Niamey. RESULT A total of 1725 persons attended the clinics between 1/12/07 and 31/01/08, including 311 presenting nonspecific signs suggesting typhoid, i.e., at least fever and headache, and 172 presenting typhoid. The incidence was 9.97% in attendees overall and 55.31% in attendees with nonspecific evocative signs. The positive predictive value of the Widal and Felix test was 53.81% and the negative predictive value was 96.35% in attendees overall and 93.13% and 70.25% respectively in patients with clinical signs. CONCLUSION Other diagnostic modalities such as PCR, coproculture, and hemoculture can be proposed, but are not available in this setting. The positive predictive value of the Widal test among patients with nonspecific signs suggesting typhoid is high. While not negligible, the negative predictive value in this high-incidence group is relatively low and should indicate monitoring.

Abstract
INTRODUCTION The aim of this study was to evaluate the results of ear defect reconstruction using the Antia-Buch flap technique and to compare it to other techniques described in international literature. MATERIALS AND METHODS We performed 19 Antia-Buch flaps between November 1998 and November 2002: 15 cases after neoplastic treatment and four post-traumatic cases. Defect ranged between 15 and 40 mm. Between 30 and 40 mm, we used Fata's modification. The final assessment took into account patient satisfaction, cosmetic aspect of reconstruction assessed by the medical team, the presence of a notch at the helical rim and the degree of microtia. RESULTS All ear reconstructions were successful. No complications were reported. Fata's modification was used for eight patients. All the patients were satisfied with the result in spite of a systematic microtia. The cosmetic aspect was considered as good for 16 patients, average for three. Nine patients presented with a notch at the helical rim. DISCUSSION Reconstruction using the Antia-Buch flap is a simple and fast operative technique performed in a single operation under local anesthesia. It allows for a harmonious reconstruction of the helix and auricle with a tissue of same nature, and only a tiny cicatricial ransom, systematic microtia and frequent notch on the helical rim.

Abstract
A high rate of cleft patients present with maxillary hypoplasia. Most of the growth defects concern the anteroposterior axis of the maxilla. Before bone lengthening by distraction osteogenesis, orthognathic surgery was the only alternative treatment for maxillary hypoplasia. Several studies showed the lack of stability after conventional surgery. In this article reviewing the literature concerning all bone lengthening procedures, the authors discuss published data on maxillary distraction osteogenesis by external and internal devices. Indications of distraction in growing children as an interceptive step are discussed.

Abstract
CASE REPORT A 23 year-old girl was admitted for a facial tumefaction, fixed to the mandible. The X-rays showed a fuzzy osteolytic lesion of the mandibular angle. The CT-scan confirmed the rupture of the cortical bone and the extension to the soft tissue. Biopsy provided the diagnosis of granulocytic monoblastic sarcoma (chloroma). Chemotherapy was efficient. DISCUSSION Mandibular localizations of chloroma are rare. Granulocytic monoblastic sarcoma is a localized tumor made of extramedullar immature granulocytes, in general associated (or more rarely preceded by) with leukemia. Early diagnosis is important because high dose chemotherapy induction may completely cure leukemia.

Abstract
INTRODUCTION We report our experience in 16 patients with a three-staged forehead flap, described by Millard (1974) and Burguet (1992) for nasal reconstruction. We wanted to determine whether the three-stage procedure improves the quality of the final aesthetic result. MATERIALS AND METHODS Sixteen patients underwent forehead flap nasal reconstruction between June 2002 and February 2005. Reconstruction was performed in three stages, a first stage for the transfer of the forehead flap on the nose, a second stage where the pediculized forehead flap was thinned (day 15) and a third stage for division of the pedicle (day 30). The quality of the final aesthetic result of nasal reconstruction was evaluated 6 months postoperatively, by the patient (patient's satisfaction with the nasal reconstruction [4 points]) and by the surgical team according to the thickness of the flap (3 points), integration of the scars (1 point), color of the flap (1 point) and the redefinition of the natural contour of the nose (1 point). A final 10-point score was used to assess the quality of the result: very good (score above 8), good (score from 7 to 8), average (score from 5 to 7) and poor (score less than 5). RESULTS Sixteen nasal reconstructions were followed to completion. Outcome was considered very good in ten (62.5%), good in three (18.7%) and fair in three (18.7%). DISCUSSION Use of the three-stage procedure for forehead flap nasal reconstruction improved the contour of the flap by aggressive defatting of the still pediculized flap, and thus improving the final aesthetic result. Traditionally two stages are used for frontal flaps, with pedicle division at the first stage. This refinement must not be excessive because of the risk of necrosis, the frontal flap often requiring latter defatting. In the three-stage technique thinning is performed at the second stage on a vascularised, bipediculized flap, which makes it possible to obtain the desired refinement without excessive vascular risk.

Abstract
BACKGROUND The authors developed a technique for the treatment of the cervical area during face lifts. The authors called this technique platysma suspension and platysmaplasty rather than plication. METHODS After an anatomical study on 10 corpses on which the authors tested the various platysma suspension techniques, they carried out platysma suspension associated with platysmaplasty in 30 patients. RESULTS This technique consists of suspending the free edge of the platysma muscle and fixing it to a resistant tissue close to the earlobe (Loré's fascia or tympanoparotid fascia). The anterior triangle of the neck was well defined, and there was no need to undermine the platysma muscle because of a perfect sliding plane between the platysma and sternocleidomastoid muscles. CONCLUSIONS This technique is both simple and effective. It generates long-lasting results, without the inconveniences or complications associated with other techniques.

Abstract
BACKGROUND Although osteogenic distraction is a well-established technique, the distraction device still needs to be improved, miniaturized, and made lighter, more flexible, and more adaptable for mandibular reconstruction in adults with gunshot wounds. The authors successively used unidirectional and bidirectional devices, followed by a bone transporter with a horseshoe-shaped trammel. The trammel system was then replaced by an endless screw, and finally by a customized endless screw. METHODS Eleven adult patients with gunshot injuries underwent mandibular reconstruction using osteogenic distraction with an external device. RESULTS An average bone gain of 79 mm was achieved. No infectious complications were observed. The authors encountered equipment problems during the study, requiring a change of material. The mean duration of mandibular distraction was 3.5 months. CONCLUSIONS Distraction of bone fragments facilitates the simultaneous expansion of soft tissues, avoiding free or pedicled myocutaneous flaps, for soft-tissue reconstruction. The alveolar ridge with the attached gum is also recreated by distraction, allowing dental reconstruction by osseointegrated implants.

Abstract
The monitoring of the odor annoyance generated by a landfill area is difficult, since it is a multi-area-sources problem, with a discontinuous odor emission. This paper proposes an adaptation of the method of sniffing team campaigns to the particular case of fresh waste odors. The method is based on the field determination of odor perception points, followed by data processing with a bi-Gaussian-type model, adapted to handle the odors. In a first step, field observers delineate the region in which odor impact is experienced and then the emission rate is manipulated in a dispersion model until the predicted size of the impact zone matches that observed in the field. In a second step the adjusted emission rate is entered into the model to calculate the percentiles corresponding to the average annoyance zone. The originality of the proposed method is the introduction of all observation points and of all recorded meteorological data into the model. The paper discusses the method limitations and the errors induced on the results, i.e. the odor emission rate and the percentile lines (or iso-concentration lines) which are used to describe the odor concentrations on a map of the surroundings of the plant. The proposed method proves to be reliable for diffuse sources, such as landfill areas. The obtained results are coherent with other results found in the literature with other techniques.

Abstract
OBJECTIVE To evaluate Quality of life (QoL) of HIV-infected children under highly active antiretroviral therapies, and its change over 18 months. MATERIALS AND METHODS QoL was evaluated by self-administred questionnaires (french versions of AUQUEI, OK-ado, and compilation of both) in 23 young living with HIV/AIDS (6-15 yrs), under antiretroviral multitherapies, and re-evaluated 18 months later in 19 of them. RESULTS At baseline, QoL in HIV-infected children-adolescents was relatively good. The answers given to each items and the mean score from infected children were similar to those obtained in uninfected healthy children. Moreover, infected adolescents distinguished definitly from healthy adolescents, describing higher QoL. The mean satisfaction score from the whole group decreased between M0 and M18 (mainly in the youngests), and mainly concerned 3 fields (self-esteem, health and school) while their somatic health remained stable or improved. An effect of the familial context was also observed for these 3 fields. CONCLUSION The progressive decline of QoL in HIV-infected children, and the surprising high and steady level of satisfaction over-time provided by the adolescents, underlined the frailty of this population and the need for a psychologic management associated to the medical follow-up. Such a multidisciplinary approach should take into account the preoccupations and difficulties of each age-class, those linked to the diagnosis itself, and to the familial or scolar contexts, in order to preserve QoL of this pediatric population, as far as possible, in a long term.

Abstract
INTRODUCTION Anhidrotic ectodermal dysplasia (AED) or Christ-Siemens-Touraine syndrome is a rare, hereditary genodermatosis, classically X-linked recessive disorder. MATERIAL AND METHODS [corrected] We report the cases of 3 children and a male adult. RESULTS The mode of diagnosis, the clinical signs and the therapeutic option are detailed. DISCUSSION AED is characterized by a malformative state derived from the ectodermal layer of the embryo which results in the triad: anhidrosis (or hypohidrosis), hypotrichosis, anodontia (or hypodontia). Hypohidrosis causes thermoregulation disorders, which in the infant, can be life threatening. It is important to recognize the affection early to avoid accidents of hyperthermia. Once the diagnosis is established, family investigations are necessary to determine whether it is a family form or a new sporadic case. Carrier mothers must be informed of the high risk recurrence for future male infants. Symptomatic maxillo-facial treatment strives to improve masticatory function and facial growth and thus limit the psychological impact and improve patient comfort.
