Clinical and histological features of histiocytoid Sweet syndrome associated with VEXAS syndrome.

BACKGROUND: "Vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic" (VEXAS) syndrome is caused by acquired somatic mutations in the ubiquitin-activating enzyme 1 (UBA1) gene. Sweet-syndrome-like skin disorders (and especially histiocytoid Sweet syndrome (HSS)) may be associated with VEXAS syndrome. OBJECTIVE: To characterize the clinical and histopathological features of HSS in patients with VEXAS syndrome. METHODS: The skin biopsies with a histological diagnosis of HSS had been collected at Rennes University Medical Center (Rennes, France) between October 2011 and January 2022. Sanger sequencing and digital PCR were used to screen skin, blood, and bone marrow samples for UBA1 variants, and thus classify patients as having VEXAS syndrome or not. We evaluated the clinical, histological, and molecular (UBA1) characteristics of patients with or without VEXAS syndrome. RESULTS: We compared 15 skin biopsies from seven patients found to have VEXAS syndrome and 19 skin biopsies from 15 patients without VEXAS syndrome. Persistent inflammatory syndrome, macrocytosis, anemia, and hematological malignancies were more prevalent in patients with VEXAS syndrome (86%, 86%, 100%, and 86%, respectively) than in patients without (36%, 40%, 53%, and 53%, respectively). These features sometimes appeared after the first skin manifestations, and a UBA1 mutation was found in the skin of five patients with VEXAS syndrome. Dermal infiltration by myeloperoxidase-positive, CD163-positive, reniform histiocytoid cells and a periadnexal distribution were more frequently observed in VEXAS syndrome biopsies (100% and 20% respectively, vs. 58% and 0% in non-VEXAS syndrome biopsies, respectively). CONCLUSION: Our findings might help the pathologist to consider a diagnosis of VEXAS syndrome and to initiate early genetic testing.

Cost-effectiveness of weekly adaptive radiotherapy versus standard IMRT in head and neck cancer alongside the ARTIX trial.

BACKGROUND AND PURPOSE: We performed a cost-effectiveness analysis (CEA) comparing an adaptive radiotherapy (ART) strategy, based on weekly replanning, aiming to correct the parotid gland overdose during treatment and expecting therefore to decrease xerostomia, when compared to a standard IMRT. MATERIALS AND METHODS: We conducted the ARTIX trial, a randomized, parallel-group, multicentric study comparing a systematic weekly replanning ART to a standard IMRT. The primary endpoint was the frequency of xerostomia at 12 months, measured by stimulating salivary flow with paraffin. The CEA was designed alongside the ARTIX trial which was linked to the French national health data system (SNDS). For each patient, healthcare consumptions and costs were provided by the SNDS. The reference case analysis was based on the primary endpoint of the trial. Sensitivity and scenario analyses were performed. RESULTS: Of the 129 patients randomly assigned between 2013 and 2018, only 2 records were not linked to the SNDS, which provides a linkage proportion of 98.4%. All of the other 127 records were linked with good to very good robustness. On the intent-to-treat population at 12 months, mean total costs per patient were €41,564 (SD 23,624) and €33,063 (SD 16,886) for ART and standard IMRT arms, respectively (p = 0.033). Incremental cost effectiveness ratio (ICER) was €162,444 per xerostomia avoided. At 24 months, ICER was €194,521 per xerostomia avoided. For both progression-free and overall survival, ART was dominated by standard IMRT. CONCLUSION: The ART strategy was deemed to be not cost-effective compared with standard IMRT for patients with locally advanced oropharyngeal cancer.

Evolution and prognostic value of left ventricular deformation and myocardial work parameters in transthyretin amyloid cardiomyopathy.

AIMS: Wild-type transthyretin amyloid cardiomyopathy (ATTR-CM) is an increasingly recognized condition. It remains challenging to estimate the extent of disease and the prognosis for most patients. Myocardial work is a sensitive echocardiographic approach that improves the characterization of myocardial damage. We investigate the parameters of myocardial deformation and work in ATTR-CM patients and their changes over time. METHODS AND RESULTS: We analysed clinical, electrocardiographic, biological, and echocardiographic characteristics in 113 patients [median age 82 (77-85), 90.4% male] diagnosed with wild-type ATTR-CM based on international consensus at a single centre. We compared the data at baseline and 18-month follow-up. Thirty-four patients died and 12 were hospitalized for heart failure at a median follow-up of 935 days (interquartile range 691-1159 days). Left ventricular end-diastolic diameter, left atrial strain during reservoir phase (LASRES), left ventricular longitudinal strain, global work index (GWI), global constructive work significantly decreased from baseline to 18 months, while left ventricular wall thickness increased. Left ventricular ejection fraction, right ventricular free wall strain (FWS), global wasted work (GWW), and global work efficiency did not alter significantly. Strain parameters were identified as prognostic on baseline evaluation using a multivariate analysis: GWI, GWW, FWS, and LASRES. They were significantly associated with the risk of death and hospitalization for heart failure. CONCLUSION: Multi-chamber strain assessment may improve the surveillance of patients with ATTR-CM, and myocardial work parameters may improve clinical risk stratification in this population.

Primary mitral regurgitation: Toward a better quantification on left ventricular consequences.

BACKGROUND: Left ventricular end-systolic diameter (LVESD) and ejection fraction (LVEF) are the parameters to look for when discussing repair in asymptomatic patients with a primary mitral regurgitation (PMR). Loading conditions are altering LV-function quantification. LV-myocardial work (LVMW) is a method based on pressure-strain loops. HYPOTHESIS: We sought to evaluate the additive value of the LVMW for predicting clinical events in patients with PMR. METHODS: 103 patients (66% men, median age 57 years) with asymptomatic severe PMR were explored at rest and during an exercise stress echocardiography. LV myocardial global work index (GWI), constructive work (GCW), wasted work (GWW), and work efficiency (GWE) were measured with speckle-tracking echocardiography at rest and low workload. The indication for surgery was based on the heart teams' decision. The median follow-up was 670 days. RESULTS: Clinical events occurred for 50 patients (48.5%) with a median of event-free survival distribution of 289 days. Systolic pulmonary artery pressure (sPAP) at rest was 32.61 ± 8.56 mmHg and did not predict the risk of event like LVEF and LVESD. Changes in, GLS (hazard ratio [HR] 0.55; 95% confidence interval (Cl): 0.36-0.83; p = .005), GWI (HR 1.01; 95% Cl: 1.00-1.02; p = .002) and GCW (HR 1.85; 95% Cl: 1.28-2.68; p = .001) in addition to Left Atrial Volume Index (HR 1.73; 95% CI: 1.28 - 2.33; p < 0,001) were independent predictors of events. CONCLUSION: Changes in myocardial work indices related to low-dose exercise are relevant to best predict PMR patient prognosis It might help to better select patient's candidate for "early-surgery."

Real-World Treatment Patterns Among French Patients With Metastatic Castration-Resistant Prostate Cancer Under Abiraterone or Enzalutamide.

PURPOSE: Using large French retrospective study cohort of chemotherapy-naïve metastatic castration-resistant prostate cancer patients (mCRPC; n = 10,308) comparing survival between patients who initiated abiraterone (ABI; 64%) and those initiating enzalutamide (ENZ; 36%), the present objective was to describe treatment patterns in the 2 years following initiation. METHOD: Using the national health data system (SNDS) from 2014 to 2018, we first explored the number of treatment lines, and secondly, patterns of patient management using state sequence analysis; cluster analyses were performed on the 0 to 12 month and 13 to 24 month periods. Age, Charlson score, and duration of androgen deprivation therapy (ADT) were obtained for each cluster in the first year of follow-up. RESULTS: Patients with only 1 treatment line accounted for 52%. In the 0 to 12 month sequence analysis, the main clusters among ABI/ENZ new users involved patients who continued the initial treatment (54% of 65% respectively) and discontinued active treatment (14.5% for both). Less than 2 years exposure to ADT prior to ABI/ENZ initiation was frequently observed for noncontrolled mCRPC, as shown in the death and switch from ABI/ENZ to docetaxel clusters. The clusters for a switch ABI/ENZ to ENZ/ABI involved 6% to 11% of the patients. CONCLUSION: Our study suggested fairly similar patterns between ABI and ENZ initiation. The cluster of patients with active treatment discontinuation needs to be further investigated, as well as factors influencing therapeutic choice. Better understanding for the use of second-generation hormone therapy in mCRPC in real life, could improve its implementation by clinicians in the early stages of prostate cancer.

Isolated functional tricuspid regurgitation: how to define patients at risk for event?

AIMS: Functional tricuspid regurgitation (TR) is a turning point in cardiac diseases. Symptoms typically appear late. The optimal timing for proposing a valve repair remains a challenge. We sought to analyse the characteristics of right heart remodelling in patients with significant functional TR to identify the parameters that could be used in a simple prognostic model predicting clinical events. METHODS AND RESULTS: We designed a prospective observational French multicentre study including 160 patients with significant functional TR (effective regurgitant orifice area > 30 mm2 ) and left ventricular ejection fraction > 40%. Clinical, echocardiographic, and electrocardiogram data were collected at baseline and at the 1 and 2 year follow-up. The primary outcome was all-cause death or hospitalization for heart failure. At 2 years, 56 patients (35%) achieved the primary outcome. The subset with events showed more advanced right heart remodelling at baseline, but similar TR severity. Right atrial volume index (RAVI) and the tricuspid annular plane systolic excursion to systolic pulmonary arterial pressure (TAPSE/sPAP) ratio, reflecting right ventricular-pulmonary arterial coupling, were 73 mL/m2 and 0.40 vs. 64.7 mL/m2 and 0.50 in the event vs. event-free groups, respectively (both P < 0.05). None among all the clinical and imaging parameters tested had a significant group × time interaction. The multivariable analysis leads to a model including TAPSE/sPAP ratio > 0.4 (odds ratio = 0.41, 95% confidence limit 0.2 to 0.82) and RAVI > 60 mL/m2 (odds ratio = 2.13, 95% confidence limit 0.96 to 4.75), providing a clinically valid prognostic evaluation. CONCLUSIONS: RAVI and TAPSE/sPAP are relevant for predicting the risk for event at 2 year follow-up in patients with an isolated functional TR.

The concomitant use of proton pump inhibitors and BRAF/MEK inhibitors in metastatic melanoma.

BACKGROUND: Proton-pump inhibitors (PPIs) are commonly used by patients with cancer, although they could reduce the absorption of oral anticancer targeted therapies. The US Food and Drug Administration states that the effect of PPIs on the efficacy of dabrafenib use by patients with metastatic melanoma is unknown. As a precautionary measure, the European Society for Medical Oncology recommends avoiding PPIs for patients receiving dabrafenib. OBJECTIVES: To determine the effect of the concomitant use of PPIs and BRAF/MEK inhibitors in patients with metastatic melanoma. METHODS: Patients with advanced melanoma receiving BRAF/MEK inhibitors as first-line treatments between 2015 and 2017 in France were selected using the French National Health Insurance database. We compared time-to-treatment discontinuation (TTD) and overall survival (OS) according to concomitant PPI exposure. We balanced the baseline characteristics of patients exposed and nonexposed to PPIs using an overlap weighting method based on a propensity score. RESULTS: The metastatic melanoma cohort comprised 1028 patients receiving BRAF/MEK inhibitors, including 361 (35.1%) patients using PPIs. PPI users had more comorbidities and a more severe metastatic disease. After having equally distributed metastatic sites and comorbidities across patients exposed and nonexposed to PPIs, concomitant PPI use was not associated with shorter TTD [weighted hazard ratio (wHR) 1.03, 95% confidence interval (CI) 0.86-1.24] or OS (wHR 1.11, 95% CI 0.88-1.39). Consistent results were observed when restricting the population to patients receiving dabrafenib, or when narrowing exposure to PPIs with stronger inhibition of cytochromes. CONCLUSIONS: In a population-based cohort of patients with advanced melanoma, the concomitant use of PPIs and BRAF/MEK inhibitors was not associated with worse outcome.

Management of epistaxis associated with oral antithrombotic drugs in emergency department and impact on prescription thereafter.

OBJECTIVES: To describe management, and to assess factors associated with antithrombotic prescription thereafter in patients who had epistaxis referred to emergency department (ED). DESIGN: Prospective cohort study. From EDs, clinical, biological and hospital data were collected. The clinical database was linked to the French Health Insurance Database where we retrieved antithrombotic drug deliveries in a 3-month period before and after referral. SETTING: Multicentric population-based cohort study within five well-defined areas. PARTICIPANTS: We considered 306 patients referred for epistaxis with a stable oral antithrombotic regimen before referral. MAIN OUTCOME MEASURES: We considered management, hospital outcome and case fatality. Antithrombotic prescription in a 3-month follow-up period was categorised into three classes: no change, class change, or discontinuation. During follow-up, hospitalisation for epistaxis or ischaemic events was searched. RESULTS: Among 306 adult individuals (mean age: 76 years), 166 took oral anticoagulant and 140 an antiplatelet drug. Blood transfusion was needed in 13.7% of patients and anterior packing alone in 61%. Half of the patients were hospitalised; 301 were discharged alive. Considering antithrombotic prescription thereafter we observed no change in 219 patients (72.8%), class changes in 47 patients (15.6%) and discontinuation in 35 patients (11.6%). We identified four independent predictors for antithrombotic prescription: hospitalisation (vs. returning home, p = .05), age (p = .03), haemoglobin level (p = .03) and oral anticoagulant (vs. antiplatelet agent, p < .001). During the 3 months following discharge, 2 thrombotic and 15 bleeding events were identified. CONCLUSIONS: Epistaxis referred to emergency department had an impact on subsequent antithrombotic prescription. CLINICAL TRIAL REGISTRATION: Clinical Trials.gov identifier: NCT02886533.

Oral Janus kinase inhibitors and venous thromboembolic events in atopic dermatitis: protocols for a case-time control study and a nested case-control study based on the French national health insurance (SNDS) cohort.

INTRODUCTION: Atopic dermatitis (AD) is a highly prevalent, chronic, inflammatory skin disease. Several orally administered Janus kinase inhibitors (JAKis, including baricitinib, upadacitinib and abrocitinib) have received a marketing authorisation for AD.Clinical trials in rheumatoid arthritis (RA) have flagged up a potential risk of JAKi-induced venous thromboembolic events (VTEs). Accordingly, the summary of product characteristics for a JAKi must mention VTEs as potential adverse drug reactions. In contrast to RA, AD per se is not associated with an elevated risk of VTEs. Assessing this potential risk among patients with AD would shed further light on the putative underlying relationship between JAKis and VTEs.Our research question is to investigate whether JAKi administration increases the risk of VTEs in adults with AD. Our primary objective is to assess the risk of VTEs in adults with AD exposed to JAKis compared to AD adults not exposed to JAKis, and our secondary objective is to evaluate whether JAKi initiation acts as a trigger of VTEs in adults with AD within 3 months. METHODS AND ANALYSIS: Hence, we have designed (1) a nested case-control study and (2) a case-time control study in a cohort of adults with AD with data from the French national health insurance system (2017-2025).Here, we describe the study protocol, our methodological choices and certain novel aspects, including the combined value of the two assumptions and the use of an exhaustive national health insurance database with potentially greater statistical power for studying rare events in the population of patients with AD at a low risk of VTEs (thus limiting the influence of confounding factors). ETHICS AND DISSEMINATION: The protocol has been approved by an independent ethics committee and registered with the French National Data Protection Commission. The study's findings will be published in peer-reviewed scientific journals and presented at international conferences.

Malnutrition and decreased food intake at diagnosis are associated with hospitalization and mortality of idiopathic pulmonary fibrosis patients.

INTRODUCTION AND AIMS: Malnutrition is frequent in patients with idiopathic pulmonary fibrosis (IPF). We examined the relationship between malnutrition at diagnosis and all-cause hospitalization, survival, and acute exacerbation in newly diagnosed IPF patients. METHODS: In this prospective cohort study, the nutritional status of 153 consecutive newly-diagnosed IPF outpatients was evaluated by measuring body mass index (BMI), fat-free mass index (FFMI) with bioelectrical impedance analysis, and food intake with the Self Evaluation of Food Intake (SEFI)®. Diagnosis was taken as the baseline date and malnutrition was defined as an FFMI below 17 (men) or 15 kg/m2 (women). To determine the factors associated with all-cause hospitalization and mortality, univariate Cox regression analyses were performed and variables with P < 0.2 were included in a stepwise multivariable analysis. RESULTS: A quarter (26%; 40/153) of the patients were suffering from malnutrition at baseline, which was more frequent (62%) in patients whose BMI was <25 kg/m2. Patients whose baseline FFMI was low were more likely to be hospitalized (Hazard Ratio (HR) = 1.98 [95% confidence interval, 1.15; 3.41], P = 0.0139) and/or die (HR = 1.79 [1.11; 2.89], P = 0.0165), but their acute exacerbation rate was similar to that of patients with normal FFMIs. Decreased food intake (SEFI®<7) at baseline was associated with all-cause hospitalization (P = 0.003) and mortality (P < 0.0001) during follow-up. Baseline higher gender-age-physiology (GAP) scores (HR = 1.24 [1.01; 1.52], P = 0.0434; HR = 1.71 [1.37; 2.14], P < 0.0001, respectively), lower BMI (HR = 0.89 [0.83; 0.96], P = 0.003; HR = 0.89 [0.82; 0.96], P = 0.003), and decreased food intake (SEFI® score) (HR = 0.81 [0.71; 0.93], P = 0.003; HR = 0.72 [0.64; 0.81], P < 0.0001), but not FFMI, were independently associated with all-cause hospitalization and mortality rates during follow-up. CONCLUSIONS: Malnutrition and decreased food intake at IPF diagnosis are associated with all-cause hospitalization and mortality. Future studies will determine whether dedicated interventions to improve food intake and nutritional status could improve outcomes for IPF patients.

The Association Between Antibiotic Use and Outcome Among Metastatic Melanoma Patients Receiving Immunotherapy.

BACKGROUND: Several observational studies have reported a decreased response to immune checkpoint inhibitors (ICI) following antibiotic use. ICI activity has been hypothesized to be impaired by antibiotic-induced gut dysbiosis. METHODS: Patients with advanced melanoma receiving an anti-PD-1 antibody as a first-line therapy between 2015 and 2017 in France were selected using the French Health Insurance database. We compared overall survival and time-to-treatment discontinuation according to antibiotic exposure in the 3 months prior to the initiation of anti-PD-1 antibody. To disentangle a causal effect of antibiotics from a confounding bias, we balanced characteristics of patients exposed and nonexposed to antibiotics using an overlap weighting method based on a propensity score. We also evaluated a control cohort of patients with advanced melanoma receiving first-line targeted therapy, as there is no rationale for decreased efficacy of targeted therapy following antibiotic treatment. RESULTS: The anti-PD-1 antibody cohort comprised 2605 individuals. Antibiotic exposure in the 3 months prior to anti-PD-1 antibody initiation was not associated with shorter overall survival (weighted hazard ratio = 1.01, 95% confidence interval = 0.88 to 1.17) or time-to-treatment discontinuation (weighted hazard ratio = 1.00, 95% confidence interval = 0.89 to 1.11). Consistent results were observed when the time frame of antibiotics was narrowed to 1 month prior to anti-PD-1 initiation or when exposure was restricted to antibiotics leading to more profound gut dysbiosis. Similar results were observed in the targeted therapy cohort. CONCLUSIONS: In a large cohort of advanced melanoma patients, we showed that antibiotic use preceding anti-PD-1 antibody was not associated with worse outcome. Physicians should not delay immunotherapy for patients who have recently received antibiotics.

Effectiveness of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers on total and cardiovascular mortality and morbidity in primary prevention: A nationwide study based on French Health Insurance Data (SNDS).

Angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs) both inhibit the renin-angiotensin system (RAS) but have different sites of action. Whether clinically meaningful differences exist is still debated. The authors set up a population-based nationwide retrospective cohort study with at least 5 years of follow-up based on the comprehensive French Health Insurance Database linked to the French hospital discharge database. Patients aged 50 or above, identified as ARB or ACE inhibitor new users in 2009 (at least one delivery during the year and no such delivery in 2008) were eligible. Exclusion criteria included history of cancer, cardiovascular disease, or chronic renal insufficiency. Main outcome measure was overall mortality. Secondary outcomes were cardiovascular deaths, major cardiovascular events, and major or other cardiovascular events. Out of 407 815 eligible patients, 233 682 (57%) were ARB users; two-third had no previous exposure to antihypertensive drug. Based on propensity-score based Cox model, ARB new user group had a better overall (HR: .878, 95%CI, .854 to .902), and cardiovascular (HR: .841, 95%CI, .800 to .84) survival and had a lower risk for major cardiovascular events (HR: .886, 95%CI, .868 to .905). Statistically significant quantitative interactions were detected with diabetes. Considering subgroup analyses, ARBs had a better survival than ACE inhibitors in nondiabetic patients.

Hospitalization for adverse events under abiraterone or enzalutamide exposure in real-world setting: A French population-based study on prostate cancer patients.

AIMS: Safety profiles of abiraterone and enzalutamide rely mainly on Phase III clinical trials. Our objective was to estimate the incidence rate ratio (IRR) for certain adverse events leading in real life to hospitalization (atrial fibrillation, acute heart failure, ischaemic heart disease, acute kidney injury [AKI], ischaemic stroke, torsade de pointe/QT interval prolongation, hepatitis and seizure), comparing abiraterone to enzalutamide. We also set out to discuss previously identified safety signals. METHOD: Using the French National Health Insurance System database, all patients newly exposed to abiraterone or enzalutamide between 2013 and 2017 and followed until 31 December 2018 were targeted. IRRs for each event were estimated using a Poisson model in a sub-population of patients without contraindications or precautions for use for either treatment. RESULTS: Among 11 534 new users of abiraterone and enzalutamide, AKI (IRR 1.42, 95% CI: 1.01-2.00), liver monitoring suggestive of hepatic damage (IRR 3.06, 95% CI: 2.66-3.53) and atrial fibrillation (IRR 1.12, 95% CI: 1.05-1.19) were significantly more often observed with abiraterone than with enzalutamide. CONCLUSION: Our study provides knowledge on abiraterone and enzalutamide real-life safety profiles, especially for events leading to hospitalization. Despite several limitations, including the lack of clinical data, the safety signal for AKI under abiraterone is in line with results of an analysis of the French pharmacovigilance database, which requires further specific investigations. Enlightening the clinicians' therapeutic choices for patients treated for prostate cancer, our study should lead to clinicians being cautious in the use of abiraterone.

Eligibility of patients with heart failure with preserved ejection fraction for sacubitril/valsartan according to the PARAGON-HF trial.

AIMS: In the heart failure (HF) with preserved ejection fraction (HFpEF) PARAGON-HF trial, sacubitril/valsartan vs. valsartan improved mortality/morbidity in patients with left ventricular ejection fraction (LVEF) below median (57%). We assessed eligibility for sacubitril/valsartan based on four scenarios. METHODS AND RESULTS: Eligibility was assessed in the Karolinska-Rennes study (acute HFpEF, LVEF ≥ 45%, and N-terminal pro-B-type natriuretic peptide ≥300 pg/mL subsequently assessed as outpatients including echocardiography) in (i) a trial scenario (all trial criteria); (ii) a pragmatic scenario (selected trial criteria); (iii) LVEF below lower limit of normal range (<54% in women and <52% in men); and (iv) LVEF below mean of normal range (<64% in women and <62% in men). Among 425 patients [age 78 (72-83) years, 57% women, 28% LVEF ≤ 57% (median in PARAGON-HF), the trial scenario, identified 34% as eligible. Left atrial enlargement and/or left ventricular hypertrophy were present in 99%. Inclusion criteria not met were diuretic treatment and New York Heart Association class. Important exclusion criteria were estimated glomerular filtration rate <30 mL/min/1.73 m2 , haemoglobin <10 g/day, and cancer. In the pragmatic scenario, 63% were eligible. In LVEF below lower limit of normal range, 5.4% were eligible, and in LVEF below mean of normal range, 41% were eligible. In patients with LVEF ≤ 57%, eligibility was 42%, 69%, 21%, and 91% according to the trial scenario, pragmatic scenario, LVEF below lower limit of normal range, and LVEF below mean of normal range, respectively. CONCLUSIONS: In real-world HFpEF (LVEF ≥ 45%) with N-terminal pro-B-type natriuretic peptide and cardiac structure/function assessed, eligibility for sacubitril/valsartan was according to PARAGON-HF complete criteria 34%, pragmatic criteria 63%, LVEF below lower limit of normal range 5.4%, and LVEF below mean of normal range 41%. Cardiac structural impairment was almost ubiquitous. Ineligibility was more due to exclusion criteria than failing to meet inclusion criteria.

Predictors of long-term outcome in heart failure with preserved ejection fraction: a follow-up from the KaRen study.

AIMS: Heart failure (HF) with preserved ejection fraction (HFpEF) has poor long-term prognosis. We assessed rates and predictors of outcome 10 years after an acute episode of HF. METHODS AND RESULTS: The Karolinska-Rennes (KaRen) study enrolled HFpEF patients with acute HF, ejection fraction ≥ 45%, and N-terminal pro-brain natriuretic peptide > 300 ng/L in 2007-11. Clinical data were collected at enrolment and after 4-8 weeks including detailed echocardiography. Follow-up data were collected 10 years after study initiation, starting from 6 months after enrolment until 2018 assessed by telephone. Independent predictors of primary (all-cause mortality or HF hospitalization) and secondary (all-cause mortality) outcomes were assessed by multivariable Cox regression. Of 539 patients, long-term follow-up data were available for 397 patients [52% female; median (interquartile range) age 79 (73, 84) years]. Over a follow-up of 5.44 (2.06-7.89) years, 1, 3, 5, and 10 year mortality rates were 15%, 31%, 47%, and 74%, respectively, with an incidence rate of 130/1000 patient-years. The primary outcome was met in 84% of the population, with an incidence rate of 227/1000 patient-years. The independent predictors of the primary outcome were tricuspid regurgitation peak velocity (m/s) [hazard ratio 1.87 (1.34-2.62)], diabetes mellitus [1.75 (1.11-2.74)], and cancer [1.75 (1.01-3.03)] while female sex was associated with reduced risk [0.64 (0.41-0.98)]. CONCLUSIONS: In HFpEF, 1, 3, 5, and 10 year mortality was 15%, 31%, 47%, and 74% and mortality or first HF hospitalization was 35%, 54%, 67%, and 84%, respectively. Independent predictors of mortality or HF hospitalization were tricuspid regurgitation peak velocity, diabetes mellitus, cancer, and male sex. In clinical management of HFpEF, attention should be paid to both cardiac and non-cardiac conditions.

Changes in prostate cancer screening practice by blood PSA testing between 2011 and 2017, a French population-based study.

OBJECTIVE: The aim of the study was to determine the trend of first blood prostate-specific antigen (PSA) test prescription in France between 2011 and 2017, based on the assumption that prostate cancer (PCa) screening is expected to decline over the years. METHOD: Using a representative sample of the French population from the French Health Insurance database, we identified 50-52-year-old men without PCa and without any blood PSA test in the five years before 2011, 2014 and 2017 (January 1-December 31 of each year). For each of these three years, the primary outcome was the first reimbursement of a blood PSA test. We used a logistic regression model with first blood PSA test as the outcome and year as the main explanatory variable. As secondary objectives, we also identified the prescriber's specialty, the urological consultation frequency, and the number of prostate biopsies in the year after the first blood PSA test reimbursement (only for 2011 and 2014). RESULTS: In 2011, 2014 and 2017, 5 275, 5 792 and 5 887 50-52-year-old men, respectively, were included. The percentage of patients with a first blood PSA test prescription decreased linearly from 2011 to 2017: 15.7% in 2011, 13.2% in 2014, and 12.4% in 2017 (p < .001). Blood PSA testing was mainly prescribed by general practitioners (>95%). The median interval between PSA tests was 13 months in 2011 and 14 months in 2014. Fewer than 10% of men had ≥1 consultation with an urologist during the year after the first blood PSA test. After the first blood PSA test, eight prostate biopsies were performed in 2011 and two in 2014. CONCLUSION: Our results suggest that in France, PCa screening is a primary care issue. Although PCa screening remains controversial and confusion exists about the best practice, our study showed a linear decrease of blood PSA test prescriptions for 50-52-year-old men between 2011 and 2017, although the reason for screening was unknown. As clinical information was not available, additional evidence is needed to determine the real impact of this decrease on the cancer-specific and overall mortality.

Acute, major muscular hematoma associated with antithrombotic agents: A multicenter real-world cohort.

BACKGROUND: There is little data on major muscular hematomas and the little there is has mainly focused on patients exposed to oral anticoagulants. OBJECTIVE: To describe the clinical characteristics, management and outcomes of patients admitted to emergency department (ED) for major muscular hematoma associated with an antithrombotic agent, and to identify predictors of in-hospital mortality. PATIENTS AND METHODS: Over a three-year period, all consecutive cases of adult patients admitted to the ED of 5 tertiary care hospitals for major muscular hematoma while exposed to an antithrombotic agent were prospectively collected and medically validated. Clinical and biological data, therapeutic management of the bleeding event, and in-hospital mortality were collected from the medical records and compared across five groups of hematoma locations. Potential confounders were taken in account using a multivariate binomial regression model. RESULTS: Three hundred and seventy-five patients were included (mean age = 81.4 years): 271 were exposed to vitamin K antagonists, 58 to parenteral anticoagulants (heparin, LMWH, fondaparinux), 33 to antiplatelets, and 13 to direct oral anticoagulants. The muscular hematomas were located in the lower limbs (n = 198), the rectus sheath (n = 71), the iliopsoas (n = 45), the upper limbs (n = 33), or elsewhere (n = 28). Reversal therapy was prescribed for 48.5% of patients, red cell transfusions for 63.6%, surgery for 12.3% and embolization for 3.5%. For 84% of patients, hospitalization was required, with a median length of stay of 10 days. Overall, in-hospital mortality was 8.5%. Reversal therapy, the need for intensive care and mortality were significantly more frequent among patients with iliopsoas hematomas. The independent predictors of in-hospital mortality were: decrease in mean arterial pressure (RR = 1.84), decrease in hemoglobin level (RR = 1.37) and the iliopsoas location (RR = 3.06). CONCLUSION: Frail elderly patients with major muscular hematomas linked to antithrombotic agents risk substantial morbidity and in-hospital mortality. The iliopsoas location was the most life-threatening bleeding site. Close observation of this population is warranted to ensure better outcomes.

Hospital databases for the identification of adverse drug reactions: A 2-year multicentre study in 9 French general hospitals.

AIMS: To estimate the actual number of adverse drug reactions (ADRs), we used the French medical administrative database (PMSI) in addition to ADRs spontaneously reported in the French Pharmacovigilance Database (FPVDB). METHODS: Capture-recapture method was applied to these 2 sources (PMSI and FPVDB), checking their independence via a third data source. The study ran from 1 July 2014 to 30 June 2016 in 9 French general hospitals. From PMSI, all discharge summaries including a selection of 10th International Classification of Diseases codes related to ADRs were analysed. This selection was based on the results of a previous study. All ADRs corresponding to these codes, spontaneously reported in the FPVDB, were included. RESULTS: In PMSI, 56.9% of hospital stays were related to an ADR (628 out of 1104). In the FPVDB, we retained 115 cases. A total of 43 ADRs were common to the 2 databases. In both sources, the most frequently reported ADRs were cutaneous (33.1 and 19.1%) and renal (25.2% and 11.6%). The most frequently suspected drugs were anti-infectives in PMSI (31.1%) and antineoplastic drugs in the FPVDB (30.4%). Using the capture-recapture method, the estimated number of ADRs was 1657 [95% CI: 1273 to 2040]. CONCLUSION: The use of the PMSI could constitute an additional tool for the estimation of the actual number of ADRs in French hospitals. A model involving a third data source enabled the independence of the 2 sources (PMSI and FPVDB) to be checked before applying the capture-recapture method.

Overall Survival Among Chemotherapy-Naive Patients With Castration-Resistant Prostate Cancer Under Abiraterone Versus Enzalutamide: A Direct Comparison Based on a 2014-2018 French Population Study (the SPEAR Cohort).

Abiraterone acetate (ABI) and enzalutamide (ENZ) are considered to be clinically relevant comparators among chemotherapy-naive patients with castration-resistant prostate cancer. No clinical trials comparing overall survival with ABI versus ENZ in a head-to-head approach have been published so far. A few observational studies with low power suggested a potential benefit of ENZ. We used the French National Health Data System to compare overall survival of new users of ABI and ENZ among chemotherapy-naive patients with castration-resistant prostate cancer in 2014-2017, followed through 2018 (the SPEAR cohort, a 2014-2018 cohort study). With an intent-to-treat approach, a survival analysis was performed, estimating hazard ratios for overall survival with the inverse probability weighted Cox model method. Among 10,308 new users, 64% were treated with ABI and 36% with ENZ. The crude mortality rate was 25.2 per 100 person-years (95% confidence interval (CI): 24.4, 26.0) for ABI and 23.7 per 100 person-years (95% CI: 22.6, 24.9) for ENZ. In the weighted analysis, ENZ was associated with better overall survival compared with ABI (hazard ratio = 0.90 (95% CI: 0.85, 0.96) with a median overall survival of 31.7 months for ABI and 34.2 months for ENZ). When restricting to 2015-2017 new users, the effect estimate shifted up to a hazard ratio of 0.93 (95% CI: 0.86, 1.01).

Androgen deprivation therapy prescription, blood and bone-density testing in a French population-based study exploring adherence to the French prostate cancer guidelines.

The safety profile of androgen deprivation therapy (ADT) is well known, and cardiovascular and osteoporosis risk factors should be assessed before ADT initiation. In order to examine whether the French Committee of Urologic Oncology Prostate Cancer (PCa) Guidelines were properly followed by clinicians, including urologists, oncologists and radiotherapists, we used a nationwide comprehensive cohort of prostate cancer patients, who were new ADT users in 2011 and were followed-up to 2013. Reimbursements for biological examinations and prescribers were identified, as well as PCa specialist consultations at drug initiation. Our results in this French cohort showed that the proportions of patients resorting to specialized care between one year and 3 months before ADT initiation and in the 6 months following was around 40% for fasting glucose and 30% for lipid assessments. Bone densitometry was performed in approximately 1% of patients. In the 12 months after ADT initiation, 75% of the patients were seen by a urologist and about 47% by an oncologist or a radiotherapist. Overall, there is still room for improvement in terms of ADT monitoring by clinicians and in the information provided to general practitioners and patients regarding the expected adverse effects of this treatment.
