BackgroundThe idiopathic inflammatory myopathies (IIMs) are a heterogeneous group of diseases that can affect the muscles, skin, lungs, heart, and joints. Increase knowledge about histopathological findings, clinical manifestations and auto-antibodies have allowed further novel classification of IIMs. Today, the main IMs subgroups are: dermatomyositis (DM), inclusion body myositis (IBM), immune-mediated necrotizing myopathies (IMNM), overlap myositis (OM) and immune-checkpoint inhibitor-related myositis (ICIrm). Axial muscle involvement results either in a “Dropped Head Syndrome (DHS)”, with a marked weakness of the neck extensors, or in a camptocormia (CC), with a weakness of the thoracolumbar paraspinal muscles. This atypical presentation is poorly described in the course of IMs while it may results in a major disability, and may lead to myositis diagnosis delay.ObjectivesThis study aimed to describe IMs revealed by DHS and/or CC. Secondary outcomes were to define subgroups of patients according to clinical, biological and histopathological characteristics. Then, the effects of treatments used were analyzed.MethodsA historical cohort was designed using the register MYOLYON which includes all IMs followed at the University Hospital of Lyon (France) between 2000 and 2021. All patients with IM revealed by DHS and/or CC and having an histologically proven IMs were included, after exclusion of alternative (e.g., myasthenia gravis, motoneuron disease). Clinical, biological, immunological, histopathological data as well as outcome and care were collected through a standardized form. Agreement for the study was obtained from the French Ministry of the Research and the study was approved by the Local Research Ethics Committee.ResultsTwenty-two patients were fully characterized: DM (n=4), IBM (n=7), OM (n=8), ICIrm (n=2) and one myositis with anti-Hu antibodies. Two groups of patients were identified according to the age at first symptoms and to the type of muscle axial involvement (e.g, DHS and/or CC). Before the age of 70 (n=13/22), the two most common diagnoses (n=11/13) were DM (n=4/4) and OM (n=7/8). Axial muscle involvement was diffuse (DHS and CC) in 10/13 patients. After 70 years old (n=9/22), there were a majority of IBM (n=6/9) and all cases of ICIrm (n=2). Axial involvement was restricted to one group of muscles (DHS or CC) in 5/9 patients. Finally, 77% (17/22) of patients had refractory disease and required a second line treatment (e.g, immunoglobulins). All of these results are summarized in the Figure 1.Figure 1.ConclusionWhile IM diagnosis is challenging in the presence of inaugural axial involvement, these results highlight the subset of IM to be considered according to the age at first symptoms and the type of axial involvement (e.g., DHS and/or CC).References[1]Mariampillai, K. et al.

BACKGROUND The integration of molecular markers into the WHO 2016 classification has clarified the complex diagnosis of gliomas. Among these biomarkers, the TERT promoter mutation and the loss of ATRX (ATRX loss) are mutually exclusive alterations associated with re-activation of telomerase or alternative lengthening of telomeres (ALT), respectively. Strangely, 25% of gliomas display neither or both these alterations, a situation referred to as abnormal telomere maintenance mechanism (aTMM). MATERIAL AND METHODS To investigate the TMM actually involved in gliomas, the C-circle (CC) assay was adapted to tumor (FFPE and frozen) samples. RESULTS We constructed a CC-based algorithm able to identify the TMM of 284 gliomas with either TERT or ATRX alteration, with a sensitivity of 100% and a specificity of 97.3%, and succeeded in deciphering the TMM involved in 122 aTMM gliomas. Additionally, the combination of the TMM, the mutational status of the Isocitrate dehydrogenase 1/2 (IDH) gene, and the histological grading was used as base for a new classification: TeloDIAG. Six subtypes are defined in this classification: tOD, tLGA, tGBM_IDHmt, tGBM, and tAIV, corresponding to oligodendroglioma, IDHmt low grade astrocytoma, IDHmt glioblastoma, and IDHwt glioblastoma, respectively, the last class gathers ALT+ IDHwt glioma. The TeloDIAG diagnosis is 99% concordant with the WHO classification for glioma displaying typical molecular characteristics (N=312). It modified the classification of 38% (N=156) discordant tumors, such as IDHwt Astrocytoma, aTMM tumors, or gliomas with unexpected TMM (e.g. TERTwt oligodendroglioma, ATRX loss GBM). Interestingly, 20% (N=69) of TERTwt, ATRXwt, or IDHwt GBM were actually tAIV, which is remarkable as tAIV-glioma patients’ survival tended to be longer (21.2 months) than tGBM patients’ survival (16.5 months). Importantly, CC in blood sampled from IDHmt astrocytoma patients was detected with a sensitivity of 56% and a specificity of 95% (N = 206). CONCLUSION In sum, the TeloDIAG is a new, simple, and efficient tool helping in glioma diagnosis and a promising option for liquid biopsy

The aim of this study was to compare the long-term clinical and radiological results between fixed (FB) and mobile bearing (MB) implants with identical design from the same manufacturer.From March 2007 to May 2009, we recruited 160 patients in a prospective, single centered, randomized controlled trial. The authors compared 81 FB total knee arthroplasty (TKA) versus 79 MB with medial compartment osteoarthritis. The same posterior stabilized HLS Noetos knee prosthesis (CORIN) was used in all patients. The two groups only differed by the tibial insert (fixed or mobile). The authors compared the postoperative Knee Society Score (KSS), the passive clinical and active radiological knee flexion, the implant survivorship, the complications, and the presence of radiolucent lines.At mean 10.5 years' follow-up (range 8-12.1 years) no significant differences were found in clinical scores (KSS (p = 0.54), pain score (p = 0.77), stair climbing (p = 0.44), passive maximum flexion (p = 0.5)) or for radiological analyses (maximum active radiological flexion (p = 0.06), presence of progressive radiolucent lines (5 (MB group) versus 6 (FB group); p = 0.75)) between groups. No significant difference was found in overall implant survivorship (82% (MB group) versus 78% (FB group) p = 0.58) or complication rate (p = 0.32) at the last follow-up.No significant clinical and radiological differences were found between fixed and mobile bearing TKA using the same semi-constrained implant type with comparable overall survivorship. The choice between a fixed or mobile bearing implant should be based on surgeon preference and experience with the selected implant.Prospective randomized controlled trial, Level II.

Pulmonary and Respiratory Medicine - Abstract
Introduction La sclerodermie systemique (ScS) est une maladie auto-immune rare, heterogene et chronique. Les pneumopathies interstitielles diffuses (PID) caracterisees par un declin progressif de la fonction respiratoire constituent une complication frequente de la ScS et sa principale cause de deces. En Europe, la prevalence de la PID-ScS a ete estimee a 1,7–4,2/100 000 individus et l’incidence annuelle a 0,1–0,4/100 000 individus. En France, l’epidemiologie de cette maladie est encore meconnue. Ainsi, les objectifs de cette etude etaient d’estimer la prevalence et l’incidence de la PID-ScS en France et de decrire les caracteristiques et la survie des patients. Methodes Une cohorte retrospective longitudinale a ete constituee a partir des donnees du Systeme national des donnees de sante entre 2010 et 2017. Les patients ont ete identifies comme etant atteints d’une PID-ScS grâce a un algorithme base sur l’utilisation de codes CIM-10. Ainsi, tous les patients de plus de 20 ans, affilies au regime general d’Assurance Maladie depuis plus de deux ans, et avec: – au moins une hospitalisation ou une affection de longue duree relative a une ScS; – au moins une hospitalisation avec un code de fibrose pulmonaire ont ete inclus. Resultats Parmi les patients identifies avec une ScS, 34 % presentaient une PID, soit 3333 patients. Les trois quarts etaient des femmes (75,6 %). La moyenne (ecart-type) d’âge etait de 60,6 (± 14,4) ans. Les principales comorbidites etaient l’hypertension (66,8 %) et le reflux gastro-œsophagien (65,8%). L’incidence globale estimee etait de 0,98–0,76/100 000 individus et la prevalence de 3,42–5,52/100 000 individus sur l’ensemble de la periode. Les taux de prevalence et d’incidence etaient trois fois plus eleves chez les femmes que chez les hommes et augmentaient avec l’âge. Les estimations de la survie globale etaient de 93 % a 1 an, 82% a 3 ans, 71 % a 5 ans et 55% a 8 ans. Les facteurs associes a la mortalite etaient le sexe masculin, la presence d’une hypertension pulmonaire, la presence d’un cancer du poumon et les classes d’âges les plus elevees. Conclusion Cette etude presente pour la premiere fois au niveau national l’epidemiologie de la PID-ScS. Notamment, elle a permis de montrer que la PID-ScS presente un taux de mortalite eleve, en particulier chez les patients a risque.

Pulmonary and Respiratory Medicine - Abstract
Introduction Les pneumopathies interstitielles diffuses (PID) regroupent un ensemble heterogene de maladies caracterisees par un processus inflammatoire diffus. Chez certains patients atteints de PID, un phenotype fibrosant progressif (FP) se developpe, comparable a celui observe dans la fibrose pulmonaire idiopathique (FPI). L’objectif de l’etude etait de fournir les caracteristiques des patients et les estimations d’incidence, de prevalence et de mortalite de la PID-FP (hors fibrose pulmonaire idiopathique) a l’echelle nationale en vie reelle. Methodes Une cohorte retrospective longitudinale de patients atteints de PID-FP a ete constituee a partir des donnees du Systeme National des Donnees de Sante (SNDS). Les patients PID-FP ont ete selectionnes selon un algorithme d’identification base sur l’utilisation de codes CIM-10 en trois etapes successives: identification des PID, exclusion des FPI, et selection des FP. Resultats 30 771 patients atteints de PID hors FPI ont ete identifies. Parmi eux, 14 413 patients (47 %) susceptibles de presenter une forme progressive ont ete inclus. Un peu plus de la moitie des patients etaient des hommes (52 %). L’âge moyen (ecart-type) etait de 68,4 ans (± 15,0). Les comorbidites les plus frequentes etaient l’hypertension (64 %) et le reflux gastro-œsophagien (55 %). La prevalence des patients avec un phenotype progressif variait de 6,6 a 19,4/100 000 individus selon l’annee et l’incidence annuelle de 3,1 a 4,7/100 000 individus. Les taux de prevalence et d’incidence etaient legerement plus faibles chez les femmes que chez les hommes, et augmentaient considerablement avec l’âge. La mediane de la survie globale a ete estimee a 3,7 ans [3,6–3,8]. Le taux de survie etait de 74 % a 1 an, 55 % a 3 ans, 42 % a 5 ans et 32 % a 8 ans. Les facteurs associes a la mortalite etaient le sexe masculin, l’âge et l’etiologie de la PID-FP. Conclusion Dans cette etude, 47 % des patients atteints de PID etaient susceptibles de presenter une forme progressive comparativement a environ 30 % dans la litterature. Cette difference pourrait s’expliquer par l’utilisation pour la selection des patients avec FP, d’un algorithme base sur l’utilisation de consommations de soin, sans possibilite de validation diagnostique des formes progressives. En conclusion, cette etude qui est la premiere a estimer l’epidemiologie des PID-FP en France grâce a l’utilisation du SNDS, suggere que les PID-FP representent au total un assez grand nombre de patients, et sont associees a un mauvais pronostic.

BACKGROUND There is a need to develop new treatments in IDH-mutant high-grade gliomas recurring after radiotherapy and chemotherapy. Based on preclinical studies showing that IDH-mutant tumors could be vulnerable to PARP inhibition we launched a phase II study to test the efficacy of olaparib (Lynparza) monotherapy in this population. METHODS Adults with recurrent high-grade IDH-mutant gliomas after radiotherapy and at least one line of alkylating chemotherapy (PCV or TMZ), KPS > 60, normal organ function were enrolled. The primary endpoint was 6 months PFS according to RANO criteria. Patients were treated with olaparib 300 mg twice daily. We used a single-stage Fleming design with p0 = 30%, p1 = 50%, a type I unilateral error rate of 5% and a power of 80%. RESULTS 35 patients with recurrent IDH-mutant gliomas (IDH1R132H-mutant n = 32, other IDH mutation n = 3, 1p/19 codeleted n = 16, 1p/19q non-codeleted n = 14) were enrolled (malignantly transformed low-grade gliomas n = 21, anaplastic gliomas n = 8, glioblastomas n = 6). Median time since diagnosis was 7.4 years (1–22 years), median time since radiotherapy was 2.8 years (0.6–18 years), median number of previous chemotherapy lines was 2 (1–5). With a median follow-up of 11 months, 30 patients had stopped treatment due to tumor progression and 2 patients were still on treatment 16 to 18 months after treatment start. At 6 months, 11/35 patients were progression-free (31 %). According to RANO criteria, based on local investigator analysis, 2 patients (5%) had a partial response and 14 patients a stable disease (37%) with a median duration of response of 9 months (4–18+). Median PFS and OS were 2.3 and 15.9 months and were similar in 1p/19q codeleted and non-codeleted patients. A grade 3 olaparib-related adverse event was observed in 5 patients (14%, lymphopenia n = 3, fatigue n = 2, diarrhea n = 1) and a grade 2 in 15 patients (43%), most frequently consisting in fatigue (23%), gastrointestinal disorders (20%) and lymphopenia (20%). No patient definitively stopped olaparib due to side effects. CONCLUSIONS In this heavily pre-treated population of recurrent IDH-mutant gliomas, olaparib monotherapy was well tolerated and resulted in some activity supporting its evaluation in association with alkylating chemotherapy in recurrent IDH-mutant gliomas in future studies.

Introduction Les pneumopathies interstitielles diffuses (PID) regroupent un ensemble heterogene de maladies caracterisees par un processus inflammatoire, diffus, et parfois fibrosant (PID) [1] . Certains patients atteints de PID fibrosante, peuvent developper un phenotype d’evolution progressive comparable a celui observe dans la fibrose pulmonaire idiopathique ; ces pathologies sont regroupees sous le terme de PID de phenotype ou de forme progressive (PID-FP) [2] . L’objectif est de decrire la frequence, les caracteristiques cliniques et l’evolution des patients PID-FP hors FPI. Methodes L’etude a porte sur tous les patients successifs hospitalises dans un centre de reference des maladies pulmonaires rares entre janvier 2010 et decembre 2017, âges de 18 ans et plus, et presentant une PID fibrosante diagnostiquee par scanner thoracique. Parmi eux, les patients presentant une PID-FP ont ete selectionnes sur les criteres de progression definis par une baisse de la CVF ≥ 10 % avec ou sans deterioration clinique, ou une baisse de la CVF entre 5 et 10 % associee a une aggravation des symptomes respiratoires, ou une baisse de la CVF entre 5 et 10 % associee a une etendue croissante de la fibrose au scanner en moins de 24 mois. Cette etude a ete approuvee par la CNIL le 09/2018 (918305). Resultats Actuellement 149 patients presentant une PID-FP ont ete inclus. La majorite des patients etaient des femmes (57 %) d’âge moyen 59 ± 14 ans. La CVF moyenne etait de 73,3 ± 21 % de la theorique et la DLco de 43,0 ± 17,5 %. Pour les 104 patients dont l’information est disponible, la duree entre le diagnostic de la PID et celui de la progression etait de 2,7 ± 3,8 ans. La repartition etiologique etait : 8 % de pneumopathie d’hypersensibilite, 6 % de pneumopathie interstitielle non specifique idiopathique, 24 % de PID inclassable, 48 % de PID auto-immune, et 14 % d’autres PID. Les criteres de progression etaient une baisse de la CVF ≥ 10 % (65 %), une baisse de la CVF de 5–10 % associee a une aggravation des symptomes (24 %), une baisse de la CVF de 5–10 % associee a une etendue croissante de la fibrose au scanner (2 %) ou une aggravation des symptomes et une etendue croissante de la fibrose au scanner (9 %) en moins de 24 mois. Conclusion Ces resultats preliminaires fournissent des elements sur l’epidemiologie des patients PID-FP pour lesquels un essai therapeutique avec le nintedanib est actuellement en cours.

Introduction Les myopathies idiopathiques inflammatoires (MIIs) sont un groupe heterogene de pathologies caracterise par une atteinte musculaire inflammatoire et des atteintes extra-musculaires variables. Plusieurs sous-groupes de MIIs sont definis a partir d’elements anatomopathologiques, immunologiques et cliniques : la dermatomyosite, la myosite a inclusions, la myosite necrosante auto-immune, le syndrome des anti-synthetases et les myosites de chevauchement. D’autres entites ont ete identifiees et apparaissent tres rares, notamment les myosites induites par les immunotherapies. Le type (myalgies, faiblesse musculaire) et la topographie (proximale ou distale) de l’atteinte musculaire est cruciale dans la demarche diagnostique, avec des tableaux variables en fonction du sous type de MIIs. L’atteinte de la musculature axiale est rare mais engendre des consequences fonctionnelles majeures. En termes semiologiques, le syndrome de tete tombante qui affecte les muscles extenseurs de la nuque se distingue de la camptocormie qui touche les muscles para-vertebraux thoraco-lombaires. Dans la litterature internationale, une trentaine de cas de syndrome de tete tombante et de camptocormie associes a des MIIs ont ete decrits, de maniere isolee ou sous la forme de petites series de cas, sans claire definition des caracteristiques cliniques, histologiques ou evolutives. L’objectif de ce travail est d’approfondir la definition du phenotype clinique et du cadre nosologique des MIIs en presence d’une atteinte musculaire axiale inaugurale en analysant de maniere exhaustive une serie de MIIs associees a une atteinte axiale inaugurale. Patients et methodes L’ensemble des cas de MIIs presentant une atteinte axiale inaugurale suivi dans un centre hospitalo-universitaire entre 2000 et 2019 ont ete inclus pour analyse. Les criteres d’inclusions correspondaient a un diagnostic de MIIs, une atteinte axiale inaugurale (tete tombante et/ou camptocormie), et l’exhaustivite des donnees clinico-bio-morpho-histologiques. Une etude descriptive ainsi que des analyses en cluster et de survie sont realisees sur cette cohorte. Resultats Dix-huit patients ont ete inclus dans l’etude. Les diagnostics de MIIs retenus etaient : scleromyosites (n = 9), dermatomyosites (n = 2), myosites a inclusions (n = 5) et myosites induites par les immunotherapies (n = 2). Certains patients presentaient a la fois un syndrome de la tete tombante et une camptocormie (n = 8), d’autres avaient seulement une atteinte des extenseurs de la nuque (n = 9) et un seul patient avait une atteinte isolee des muscles para-vertebraux thoraco-lombaires (n = 1). Le suivi moyen etait de 7 ans et demi. L’atteinte de la musculature axiale etait inaugurale ou survenait dans la premiere annee d’evolution de la MII pour les 18 patients, survenant dans 50 % des cas de maniere aigue ou rapidement progressive (i.e. Conclusion Dans ce travail descriptif, analysant la plus grande serie de cas de MIIs avec atteinte axiale inaugurale, cette symptomatologie rare semble retrouvee de facon predominante au cours des scleromyosites et des myosites a inclusions. Selon la pathologie sous-jacente, la presentation clinique est variable. L’installation est plus insidieuse dans les myosites a inclusion, la reponse au traitement est moindre alors que la morbidite induite est importante. L’evolution peut etre consideree comme superposable aux pathologies neurodegeneratives. A l’inverse, en cas d’installation aigue, la presence d’une telle atteinte semble tirer benefice d’un traitement maximal.

International audience; BACKGROUND: Cytoreductive surgery (CRS) and Hyperthermic intraperitoneal chemotherapy (HIPEC) are promising new approaches of peritoneal metastases. However these surgical procedures are associated with a high morbidity rate thus intensive care (IC) management following serious complications may be warranted for these patients. The impact of the prolonged IC stay or re-admission on long-term survival remains unknown. METHODS: We retrospectively analysed 122 consecutive HIPEC procedures over a one year period (2010-2011) in a single academic hospital. We analysed complications that would lead to prolonged stay or re-admission into ICU and analysed long term follow-up in patients whether they required intensive care (ICU group) or not (Control group). RESULTS: ICU group represented 26.2% of the cohort mainly due to septic or haemorrhagic shock. Among them acute kidney injury and respiratory failure were present in 50% and 47% respectively. Cohort overall mortality rate was of 5.7%. Patients were followed for 4 years and survival analysis was performed adjusting for main confounding factors in a Cox survival model. Survival was not different between groups, with a median survival of 38 months [32; 44] vs. 33 months [26; 39] in the ICU group and Control group respectively. CONCLUSION: Prolonged stay or re-admission into ICU does not seem to statistically impact long term prognosis of patients undergoing CRS with HIPEC.

Rheumatology - Abstract
Introduction La sclerodermie systemique (ScS) est une maladie auto-immune rare, heterogene, et chronique. Les pneumopathies interstitielles diffuses (PID) caracterisees par un declin progressif de la fonction respiratoire constituent une complication frequente de la ScS et sa principale cause de deces. En Europe, la prevalence de la PID-ScS a ete estimee a 1,7–4,2/100 000 individus et l’incidence annuelle a 0,1–0,4/100 000 individus. En France, l’epidemiologie de cette maladie est encore meconnue. Ainsi, les objectifs de cette etude etaient d’estimer la prevalence, l’incidence de la PID-ScS en France et de decrire les caracteristiques et la survie des patients. Patients et methodes Une cohorte retrospective longitudinale a ete constituee a partir des donnees du Systeme National des Donnees de Sante entre 2010 et 2017. Les patients ont ete identifies comme etant atteints d’une PID-ScS grâce a un algorithme base sur l’utilisation de codes CIM-10. Ainsi, tous les patients de plus de 20 ans, affilies au regime general d’Assurance Maladie depuis plus de deux ans, et avec : – au moins une hospitalisation ou une affection de longue duree relative a une ScS ; – au moins une hospitalisation avec un code de fibrose pulmonaire ont ete inclus. Resultats Parmi les patients identifies avec une ScS, 34 % presentaient une PID, soit 3 333 patients. Les trois quarts etaient des femmes. La moyenne (ecart-type) d’âge etait de 60,6 (± 14,4) ans. L’incidence globale estimee etait de 0,98–0,76/100 000 individus et la prevalence de 3,42–5,52/100 000 individus sur l’ensemble de la periode. Les taux de prevalence et d’incidence etaient environ trois fois plus eleves chez les femmes que chez les hommes et augmentaient considerablement avec l’âge. Les estimations de la survie globale etaient de 93 % a 1 an, 82 % a 3 ans, 71 % a 5 ans et 55 % a 8 ans. Les facteurs associes a la mortalite etaient le sexe masculin, la presence d’une hypertension pulmonaire, la presence d’un cancer du poumon et les classes d’âges les plus elevees. Discussion La principale limite de l’etude pouvant impacter l’incidence et la prevalence repose sur les modalites de selection des patients et le risque de non-inclusion des patients n’ayant pas ete hospitalises. Neanmoins, les resultats sont coherents avec les donnees de la litterature. Conclusion Cette etude presente pour la premiere fois au niveau national l’epidemiologie de la PID-ScS. Notamment, elle a permis de montrer que la PID-ScS presente un taux de mortalite eleve, en particulier chez les patients a risque.

The objective of this study was to analyze the long-term efficiency and tolerance of TB in the management of anticholinergic refractory hyperactive bladder in patients with MS.Retrospective mono-centric cohort study of all patients with MS who had a TB injection for anticholinergic refractory hyperactivity from 2005 to 2015. The primary endpoint was clinical efficiency based on the frequency of urinary leakage and symptomatic urinary tract infections.One hundred and nineteen patients received the first injection. Median follow-up was 26.5 months. After an injection, there was a significant decrease in the number of leaks, with 69.7% of patients without leaks and 93.3% of patients without urinary tract infections. After 7 injections 44% of the patients were still dry and 62.07% had no symptomatic urinary tract infections. The failure rate was 24.37%, the average duration before discharge was 34.7 months. 19 (66%) patients stop treatment for loss of efficacy, 9 (31%) for disease progression and 1 (3%) for cessation of treatment without cause. Of the 774 injections performed, there were complications for 26 of them (3.35%).Botulinum toxin remains the second-line reference treatment for detrusor overactivity of neurological origin. There is, at least in the short term, a good answer in a large number of cases. This response can be maintained for many years, especially if patients use intermittent catheterization, with excellent tolerance.4.

Compare the length of hospital stay and the complications after HoLEP between three groups of patients: a control group, a group with antiplatelet therapy, a group with anticoagulation therapy.Retrospective cohort study that included all consecutive patients who underwent HoLEP for prostatic hyperplasia in our center from may 2013 to may 2016. Anticoagulated patients and patients under clopidogrel had respectively a relay with heparine and aspirine. Patients were seen after surgery at 1 and 3 months.A hundred and fifty six patients were analysed, mean age was 70.7 years (DS 6.8), mean prostate volume 88.8g (DS 34.1). 106 patients were in the control group, 34 had antiplatelet therapy and 16 had anticoagulation therapy. There were no difference between the 3 groups for mean age, mean prostatic volume, PSA. There was also no difference for length of intervention, irrigated volume and length of morcellation between the three groups. There were no difference between patients in the control group and patients with antiplatelet therapy for length of hospital stay (2.1 days vs 2.0 days), lenght of urethral catheterization (1.6 days vs 1.5 days). There was a statistical difference between patients in the control group and patients with anticoagulation therapy for lenght of hospital stay (2.0 days vs 4.4 days; P=0.01), length of bladder irrigation (0.9 day vs 1.8 days; P=0.01), lenght of urethral catheterization (1.6 days vs 3.5 days; P=0.01). Transfusion rate was 18.75% (n=3) for patients with anticoagulation, 2.9% (n=1) for patients under antiplatelet therapy and 0.9% (n=1) for patients in the control group.Anticoagulation during HoLEP is a valid option but need to be proceed with carefully management.4.

Cardiac output (CO) measurement is crucial for the guidance of therapeutic decisions in critically ill and high-risk surgical patients. Newly developed completely non-invasive CO technologies are commercially available; however, their accuracy and precision have not recently been evaluated in a meta-analysis. We conducted a systematic search using PubMed, Cochrane Library of Clinical Trials, Scopus, and Web of Science to review published data comparing CO measured by bolus thermodilution with commercially available non-invasive technologies including pulse wave transit time, non-invasive pulse contour analysis, thoracic electrical bioimpedance/bioreactance, and CO2 rebreathing. The non-invasive CO technology was considered acceptable if the pooled estimate of percentage error was30%, as previously recommended. Using a random-effects model, sd, pooled mean bias, and mean percentage error were calculated. An I2 statistic was also used to evaluate the inter-study heterogeneity. A total of 37 studies (1543 patients) were included. Mean CO of both methods was 4.78 litres min−1. Bias was presented as the reference method minus the tested methods in 15 studies. Only six studies assessed the random error (repeatability) of the tested device. The overall random-effects pooled bias (limits of agreement) and the percentage error were −0,13 [−2.38 , 2.12] litres min−1 and 47%, respectively. Inter-study sensitivity heterogeneity was high (I2=83%, P0.001). With a wide percentage error, completely non-invasive CO devices are not interchangeable with bolus thermodilution. Additional studies are warranted to demonstrate their role in improving the quality of care.

BACKGROUND in large unselected series, the median age of Primary CNS Lymphoma (PCNSL) patients (pts) is about 70 years. In one USA cancer registry study for PCNSL patients older than 65 years, 14% of them are older than 80 years. Data on clinical characteristics, therapeutical management, toxicity of treatment and outcome of these very elderly pts are limited. MATERIAL AND METHODS we reviewed PCNSL pts aged of 80 years or older included in the database of the French Oculo-Cerebral lymphoma (LOC) network. From January 2011, this network prospectively recorded all newly diagnosed PCNSL from 22 regional expert centers in France. RESULTS 110 pts with a DLBCL PCNSL aged of 80 years or older were diagnosed between January 2011 and January 2018 representing 8% of pts available in the LOC database. The clinical characteristics were as follows: 63% of females; median age: 83y (80–92); performance status (PS) ≥3, 55% of pts. Median creatinine clearance (CKD.EPI) was 70ml/min. Treatment was initiated either by a neuro-oncology or a hematology team in 35% and 65% of cases, respectively. First line treatment was high-dose (HD) methotrexate (MTX) based chemotherapy (CT) in 85 pts (77%), other chemotherapy regimen in 13 pts (12%) and palliative care in 12 pts (11%). Interestingly, no difference of distribution for the main clinical and biological characteristics was observed between these three groups. After first-line induction chemotherapy, response rate for evaluable patients (n=85) were as follows: 37% of complete response, 9% of partial response, 54% of stable or progressive disease. Rituximab was used in combination with CT in 53/98 treated pts (54%). For toxicity, among the 351 infusions performed for the 85 pts who received MTX-based CT, grade 3–4 toxicities were: 46% of any events, 15% of infection, 13% of cytopenia, 11% of acute renal failure and 8% of elevated liver enzymes. 13% of pts presented toxic death. Median progression free survival (PFS) and overall survival (OS) were 5 months and 8 months, respectively. Pts treated with MTX-based CT had a significantly prolonged PFS and OS. In the univariate analysis performed for the 85 pts treated with MTX-based CT, no initial clinical and biological influenced PFS or OS. Intravenous rituximab used in first line therapy significantly improved PFS and OS. CONCLUSION in this large series of consecutive PCNSL pts aged of 80y or over prospectively recorded in a national database, we showed that the prognosis remains poor with major toxicity under conventional treatment. No clinical predictor of survival was highlighted in our series. Patients initially treated with MTX-based CT in combination with rituximab had an improved outcome. The development of target and innovative therapies is needed for this category of patients representing 8% of all PCNSL in the database of the LOC network.

Background and purpose Optimal surgical resection improves the prognosis of glioblastomas. However, this goal is far from being achieved due to its invasive nature. Several studies have already shown the efficacy of fluorescence-guided surgery, in improving the quality of resection of glioblastoma. We report herein our experience through a retrospective serie and describe the principles, limitations and advantages of this technique. Methods Between 2006 and 2009, 22 patients underwent resection of a glioblastoma guided by fluorescence. Following operations, all patients underwent sequential clinical examination and radiological monitoring using multimodal MRI. The extent of resection was assessed by the surgeon during the procedure and by the radiologist on MRI. The curves of progression-free clinical survival (SSP) and overall survival (SG) were analyzed. The prognostic value of the extent of resection was studied. Results We obtained 68.2% of complete resection according to the absence of residual fluorescence as assessed by the surgeon, and 75% according to the absence of residual tumor on early MRI. The median SSP was 10.75 months and the median SG was 17 months. Complete tumoral resection confirmed by loss of fluorescence significatively increases the median SSP of 6.7 months to 12.9 months (p = 0.001559) and the median SG of 12.3 months to 20.9 months (p = 0.000559). After 1 year, 81.8% of patients were still alive. Conclusions Our study confirms the use of fluorescence as an effective method to allow optimal resection of glioblastoma. In addition to neuronavigation, surgical experience, vision and proprioception, fluorescence contributes to achieve a complete tumor resection.

Introduction Occult paroxysmal atrial fibrillation (PAF) may cause a significant part of ischemic strokes (IS) or transient ischemic attacks (TIA) remaining unexplained in 20 to 40% after standard care. Thus, invasive monitoring for PAF screening is recommended but remains silent in more than 80% of patients after 6 months. Also, non invasive transthoracic echocardiography (TTE) can help to predict PAF by assessing of atrial volumes and diastolic function. However, diastolic function classification requires a complex approach. Objective Transmitral E/A ratio drives a significant part of diastolic function evaluation. It is also influenced by atrial systolic function, often impaired in between PAF periods. We hypothesized that E/A increases in the acute phase of IS or TIA related to occult PAF, independently of traditional variables associated with PAF such as age and left atrial volume (LAv). Method A retrospective cohort of IS or TIA patients were included. TTE was performed in sinus rhythm within 30 days after IS or TIA. We excluded LVEF Results Between Jan 2015 and Apr 2017, 682 patients were included (101 PAF and 581 non-PAF). Main characteristics are shown in Table 1 . In multivariable logistic regression, only age, LAv, A/E and LVmass were predictive of PAF. ROC curves for prediction of PAF were significantly better when integrating successively, LAv (AUC 0.75) over age alone (AUC 0.70), and E/A (AUC 0.79) over age + LAv (AUC 0.75); P Fig. 1 ). Conclusion The simple and accessible E/A ratio is an independent predictor of occult PAF in the acute phase of ischemic stroke and may help to stratify patients for invasive monitoring.

Introduction/objectifs/but Centres de recours sur le territoire, les CHU ont un role central a jouer dans le developpement de la tele-expertise. Pour que le systeme soit performant, il convient de valoriser et organiser cette pratique medicale au benefice des medecins generalistes ou specialistes et des etablissements partenaires. Une enquete a ete menee aux hospices civils de Lyon afin d’etablir un etat des lieux des pratiques actuelles sur les avis rendus, et de degager les actions prioritaires pour developper la tele-expertise. Materiel et methode Un questionnaire electronique en 8 questions a choix multiples a ete developpe et valide en Commission medicale d’etablissement. Le lien vers l’enquete a ete adresse par courriel a l’ensemble des praticiens seniors. Resultats/observations Parmi les 2619 praticiens invites a repondre, 23,4 % ont valide leur questionnaire. Les resultats montrent que l’activite d’expertise couvre l’ensemble de la region Rhone-Alpes-Auvergne, et s’etend a l’international. Un tiers des praticiens consacrent plus de 225 h par an a une activite d’expertise en dehors du CHU. Les pratiques actuelles respectent peu la reglementation et favorisent l’absence de tracabilite. Les sollicitations des patients justifient d’organiser les modalites de reponse. Afin d’ameliorer l’activite d’expertise et favoriser la tracabilite des avis rendus, deux outils ont ete co-construits par la DSII et les medecins des HCL, en conformite avec les obligations du decret de telemedecine de 2010. MyHOPPro permet d’organiser la tele-expertise, garantit la securite et la confidentialite des echanges entre les professionnels. Le portail MyHOP permet un telesuivi des patients pour preparer, accompagner une hospitalisation et securiser le retour a domicile.

International audience; Current antihypertensive strategies do not take into account that individual characteristics may influence the magnitude of blood pressure (BP) reduction. Guidelines promote trial-and-error approaches with many different drugs. We conducted the Identification of the Determinants of the Efficacy of Arterial blood pressure Lowering drugs (IDEAL) Trial to identify factors associated with BP responses to perindopril and indapamide. IDEAL was a cross-over, double-blind, placebo-controlled trial, involving four 4-week periods: indapamide, perindopril and two placebo. Eligible patients were untreated, hypertensive and aged 25-70 years. The main outcome was systolic BP (SBP) response to drugs. The 112 participants with good compliance had a mean age of 52. One in every three participants was a woman. In middle-aged women, the SBP reduction from drugs was -11.5 mm Hg (indapamide) and -8.3 mm Hg (perindopril). In men, the response was significantly smaller: -4.8 mm Hg (indapamide) and -4.3 (perindopril) (P for sex differences 0.001 and 0.015, respectively). SBP response to perindopril decreased by 2 mm Hg every 10 years of age in both sexes (P=0.01). The response to indapamide increased by 3 mm Hg every 10 years of age gradient in women (P=0.02). Age and sex were important determinants of BP response for antihypertensive drugs in the IDEAL population. This should be taken into account when choosing drugs a priori.

Optimal surgical resection improves the prognosis of glioblastomas. However, this goal is far from being achieved due to its invasive nature. Several studies have already shown the efficacy of fluorescence-guided surgery, in improving the quality of resection of glioblastoma. We report herein our experience through a retrospective serie and describe the principles, limitations and advantages of this technique.Between 2006 and 2009, 22 patients underwent resection of a glioblastoma guided by fluorescence. Following operations, all patients underwent sequential clinical examination and radiological monitoring using multimodal MRI. The extent of resection was assessed by the surgeon during the procedure and by the radiologist on MRI. The curves of progression-free clinical survival (SSP) and overall survival (SG) were analyzed. The prognostic value of the extent of resection was studied.We obtained 68.2% of complete resection according to the absence of residual fluorescence as assessed by the surgeon, and 75% according to the absence of residual tumor on early MRI. The median SSP was 10.75 months and the median SG was 17 months. Complete tumoral resection confirmed by loss of fluorescence significatively increases the median SSP of 6.7 months to 12.9 months (p=0.001559) and the median SG of 12.3 months to 20.9 months (p=0.000559). After 1 year, 81.8% of patients were still alive.Our study confirms the use of fluorescence as an effective method to allow optimal resection of glioblastoma. In addition to neuronavigation, surgical experience, vision and proprioception, fluorescence contributes to achieve a complete tumor resection.

Introduction Le curage axillaire (CA) induit un lymphœdeme, des troubles fonctionnels et une reduction de la qualite de vie (QDV) [1] . Le bloc paravertebral (BPV) permet de diminuer la douleur aigue et chronique postoperatoire en chirurgie majeure du sein [2] , [3] . Notre hypothese est que le BPV ameliore la recuperation fonctionnelle et la QDV a 3 mois postoperatoires du CA. Materiel et methodes Etude observationnelle prospective monocentrique, approuvee par le comite d’ethique. Toutes les patientes avaient une anesthesie generale pour la chirurgie de CA. Certaines recevaient un BPV en preoperatoire, selon le type de chirurgie associee et le choix de la patiente. Une evaluation postoperatoire etait realisee a 7, 21 jours et 3 mois. Au cours de chaque evaluation, le parametre recueilli etait un score de QDV axe sur les troubles fonctionnels du membre superieur (QuickDash). En postoperatoire precoce, la consommation de morphine, la douleur et les amplitudes articulaires etaient evaluees. Le critere principal etait le QuickDash a 3 mois. Les donnees ont ete decrites en effectifs et pourcentages pour les variables qualitatives, mediane et quartiles, pour les variables quantitatives. Les comparaisons ont ete realisees a l’aide de tests non parametriques. Les analyses ont ete realisees avec le logiciel R (software 3.0.2). Resultats Entre avril 2012 et juillet 2013, 61 patientes ont ete inclues. Vingt-deux ont beneficie d’un BPV. Dans les 2 groupes, les patientes etaient comparables sur les donnees demographiques. Les BPV etaient realises avec un volume de 29,5 [20–30] mL d’une solution contenant : ropivacaine 7,5 mg/mL, clonidine 2,5 μg/mL et adrenaline 2,5 μg/mL. La duree de realisation etait de 10 [10–15] min. Aucune complication n’a ete recensee. Les doses de remifentanil peroperatoires et le nombre de patientes ayant recours aux antalgiques de secours (morphine et tramadol) etaient significativement inferieurs dans le groupe BPV sans difference sur les scores de douleur, les amplitudes articulaires ou les scores de lymphœdeme jusqu’a j21. Aucune des patientes ayant eu un BPV n’a eu besoin de morphine postoperatoire. La presence du BPV diminuait de maniere significative le QuickDash a 3 mois (p = 0,043) traduisant une amelioration de la QDV. L’evolution de ce score etait identique dans les 2 groupes. Cependant, le groupe sans BPV avait un score QuickDash systematiquement superieur au groupe avec BPV, signifiant une QDV moins bonne a tous les temps de l’etude. La presence d’un lymphœdeme et de douleur residuelle a 3 mois etait associee a une diminution de la QDV (p = 0,002). Discussion Le BPV ameliore la recuperation fonctionnelle et la QDV a 3 mois postoperatoires de CA. Les hypotheses peuvent etre la diminution de la douleur aigue et chronique dans le groupe BPV permettant une rehabilitation plus precoce par les kinesitherapeutes. Les limites de cette etude sont principalement son caractere observationnel et des donnees perdues concernant la radiotherapie et la technique de kinesitherapie qui pourraient influencer les resultats. Le score QuickDash n’explore que la QDV liee a l’atteinte fonctionnelle du membre superieur.

Introduction La presence de lesions atheromateuses carotidiennes est frequente chez les patients diabetiques. Par ailleurs, si le risque d’accident vasculaire cerebral est augmente chez les patients avec un atherome carotidien, le risque apparait plus eleve chez les patients presentant des lesions evolutives. Un suivi de la progression de l’atherome pourrait etre un element utile pour cibler les patients les plus a risque. Nous avons analyse l’evolution des lesions atheromateuses carotidiennes par echographie doppler chez une cohorte de patients diabetiques. Patients et methodes Trois cent quarante-deux patients diabetiques ont ete inclus entre 1993 et 2010. Les resultats du doppler ont ete classe en normal (Absence de lesion atheromateuse), lesion 50 % (ratio de vitesse > 2). La progression a ete definie pour un patient donne comme le passage a un degre de severite superieur, une regression comme le passage a un degre inferieur. L’âge moyen au premier doppler etait de 59,2 ± 10,8 annees et l’anciennete du diabete de 13,6 ± 11,4 annees. Au total, sur l’ensemble du suivi, 1 014 dopplers ont ete realises soit 3 dopplers par patient. Le delai moyen entre deux examens etait de 2,7 ± 2,1 annees. Le suivi moyen a ete de 6,4 ± 4,6 annees. Resultats Initialement 31,3 % des patients avaient un doppler normal, 64,6 % une lesion 50 %. Une progression a ete observee pour 20,1 % des patients avec un delai moyen de 6,5 ± 5,3 annees soit une progression annualisee de 3,1 %. Une regression a ete constatee pour 11 % des patients. Aucun patient sans lesion initiale n’a developpe au cours du suivi de lesion > 50 %. Six patients ont beneficie d’une chirurgie carotidienne. Conclusion L’evolution des lesions carotidiennes reste un element frequent dans la population diabetique. Toutefois les indications de chirurgie carotidienne restent rares et l’impact du suivi sur la prise en charge therapeutique reste a demontrer dans une etude prospective.

Introduction Le diabete est un facteur de risque de lesions atheromateuses carotidiennes dont la presence s’associe a un sur-risque d’accident coronarien et d’accident vasculaire cerebral. Si le depistage systematique des lesions carotidiennes n’est generalement pas recommande, il est encore couramment realise en pratique clinique. Nous avons estime la prevalence des lesions carotidiennes diagnostiquees a l’echo-doppler sur une cohorte de patients diabetiques et analyse l’impact therapeutique de cette pratique. Patients et methodes Huiti cent trois patients âges en moyenne de 61,5 ± 12,3 ans ayant eu un echo-doppler arteriel carotidien en 2012 ont ete inclus. L’association d’un atherome carotidien avec des facteurs candidats a ete testee. Nous avons compare les modifications therapeutiques en terme de prevention cardio-vasculaire preconisees par les recommandations 2013 de l’ADA et 2014 de l’ACC/ AHA aux resultats du doppler. Resultats 85,5 % des patients avaient un diabete de type 2. L’HbA1C etait en moyenne a 8,6 ± 2 %. Initialement 65 % des patients etaient sous statines, 43 % sous antiagregants plaquettaires et 66 % sous IEC ou ARA2. 16,7 % etaient en prevention secondaire cardio-vasculaire. Seuls 31,3 % des patients n’avaient aucune lesion atheromateuse. 35,9 % presentait des lesions avec une reduction de calibre 50 %. Les facteurs significativement associes a l’existence d’une lesion etaient la presence d’une hypertension, d’un diabete de type 2, d’une arteriopathie des membres inferieurs et d’une neuropathie. Aucun patient n’a eu d’indication de prise en charge chirurgicale carotidienne. L’instauration d’une statine ou d’un antiagregant plaquettaire etait preconisee dans respectivement 95,8 et 45,2 % des patients avec une lesion en suivant les recommandations ADA et une statine dans 71,4 % des cas en suivant les recommandations ACC/AHA. Conclusion Notre etude confirme la prevalence importante des lesions carotidiennes dans la population diabetique. Toutefois les recommandations ADA permettent une optimisation du traitement cardio-protecteur dans une grande majorite des cas. L’interet additionnel du doppler des carotides semble limite. Declaration d’interet Les auteurs declarent ne pas avoir d’interet direct ou indirect (financier ou en nature) avec un organisme prive, industriel ou commercial en relation avec le sujet presente.

Cardiology and Cardiovascular Medicine - Abstract
Nous avons mene l’analyse de 810 examens Doppler des troncs supra-aortiques (TSA) realises chez des patients diabetiques dans le cadre du depistage de l’atherome carotidien dans cette population au cours de l’annee 2012. Les resultats ont ete classes en quatre categories : – examen normal (pas de lesion retrouvee) ; – epaississement ou surcharge parietale (inferieur a 20 % de reduction de calibre ou inferieur a 2 mm d’epaisseur) ; – plaques non stenosantes (inferieures a 50 % de reduction de calibre et ratio de pics systoliques inferieur ou egal a 2) ; – plaques stenosantes (superieures ou egales a 50 % de reduction de calibre et ratio de pics systoliques superieur a 2). Les analyses ont ete realisees a l’aide de regressions logistiques univariees puis multivariees. Les variables etaient retenues lorsque la p-value etait inferieure a 5 %. Un examen Doppler normal etait retrouve chez 251 sujets diabetiques (31,2 % des cas). Les epaississements parietaux etaient decrits chez 289 personnes (35,9 %), tandis que les plaques non stenosantes chez 231 sujets (28,7 %) et les plaques stenosantes dans 33 cas (4,1 %). Les facteurs predictifs d’un examen Doppler pathologique (presence de plaques non stenosantes et stenosantes ou d’epaississements parietaux 65,6 %) sont : – l’hypertension arterielle (p = 0,0004 avec OR = 1,958 [IC 95 % 1,353–2,833]) ; – la dyslipidemie (p – l’arteriopathie obliterante des membres inferieurs (p = 0,0061 avec OR = 2,687 [IC 95 % 1,327–5,444]) ; – la neuropathie (p = 0,0006 avec OR = 1,864 [IC 95 % 1,308–2,655]). Les facteurs predictifs d’un examen Doppler severe (Doppler avec une plaque stenosante 4,1 %) sont : âge superieur a 50 ans et l’arteriopathie obliterante des membres inferieurs (p = 0,0007 avec OR = 3,614 [IC 95 % 1,718–7,606]). Dans un dernier temps, nous avons cherche a analyser les consequences therapeutiques suite a la realisation d’un examen Doppler des troncs supra-aortiques. Dans 4,5 % des cas, une statine etait introduite ; dans 9,7 % des cas un antiagregant plaquettaire, dans 5,2 % un IEC ou ARA2, dans 0,6 % un avis chirurgical etait preconise, et dans 2 % des cas une imagerie complementaire (angioscanner ou angio-IRM des TSA). Une surveillance par un prochain examen Doppler etait proposee pour 62,5 % des sujets. Par consequent, il est preconise de ne realiser un Doppler des TSA, en l’absence de signe clinique, que chez les patients diabetiques âges de plus de 50 ans presentant une arteriopathie obliterante des membres inferieurs.

Objectif evaluer la frequence des prescriptions hors/sans AMM en neonatologie. Methode etude prospective realisee dans 2 services de neonatologie a Lyon pendant 1 an (2012). Le statut AMM est determine selon la base de donnees du medicament Theriaque 2012. Resultat Sur 8891 prescriptions, 59.5% (IC 95%: 58.5 – 60.5) sont utilisees hors AMM, et 5.2% (IC 95%: 4.7 - 5.7) sans AMM. Parmi les 910 patients inclus, 863 (94.8%) ont recu au moins une prescription hors AMM dont 100% enfants moins de 31 semaine d’âge gestationel. Pres de 60% des medicaments utilises hors AMM sont pour un non-respect de l’âge. Les facteurs determinants des prescriptions hors AMM, sont l’âge gestationnel et la duree de sejour. Plus l’âge gestationnel est petit (OR = 0.106, IC 95% : 0.045 – 0.254, p –3 ) et plus la duree de sejour est importante (OR = 1.1 95% CI (1.04 – 1.16), p –3 ), plus le risque d’etre confronte aux prescriptions hors AMM est important. Les medicaments les plus prescrits sont les vitamines, les antibiotiques, les medicaments du systeme nerveux, avec une part importante de prescriptions hors AMM dans chacune de ces categories. Conclusions La prescription hors AMM est largement repandue en neonatologie. Les consequences de cette utilisation doivent etre etudiees.

- Abstract
Background: Low-risk gestational trophoblastic neoplasia are currently receiving monochemotherapy as first-line therapy. In the case of a resistance, a second-line monochemotherapy or polychemotherapy is proposed. As an alternative to these toxic and historic chemotherapy agents, the efficacy of the anti-PD-L1 monoclonal antibody (avelumab) was assessed in the TROPHIMMUN phase II trial Cohort A. Avelumab yielded a 53% cure rate with an acceptable tolerance profile, including normal further pregnancy and delivery. Beyond the blockade of PD-1/PD-L1 interactions, avelumab effect could rely on the induction of antibody-dependent cell-mediated cytotoxicity mediated by FcγR3A-expressing natural killer cells., Objective: This translational study aimed at testing whether antibody-dependent cell-mediated cytotoxicity is involved in avelumab efficacy on gestational trophoblastic neoplasia and if FcγR3A affinity polymorphism could help predicting the response to avelumab in gestational trophoblastic neoplasia., Study Design: The expression of PD-L1 by the tumor and the phenotype of natural killer cells infiltrating gestational trophoblastic neoplasia were verified by performing transcriptomic and proteomic analyses. Then, JEG-3 choriocarcinoma cells were cocultured with human natural killer cells in the presence and absence of avelumab. The impact of FcγR3A functional polymorphism was assessed on the activation status of natural killer cells and the viability of JEG-3 choriocarcinoma cells. Finally, the data from TROPHIMMUN trial were re-analyzed to determine the impact of the FcγR3A polymorphism of patients on their response to avelumab., Results: We confirmed that FcγR3A+ natural killer cells infiltrated PD-L1-expressing gestational trophoblastic neoplasia. In vitro, avelumab-coated JEG-3 choriocarcinoma cells induced natural killer cell activation, which promoted the destruction of JEG-3 cells. Natural killer cell activation was abolished when the Fc portion of avelumab was removed, demonstrating the importance of Fcγ receptor in this process. Using this model of antibody-dependent cell-mediated cytotoxicity, we demonstrated that high-affinity FcγR3A polymorphism on natural killer cells was associated with better in vitro response to avelumab. In line with this result, patients from the TROPHIMMUN trial homozygous for the high-affinity FcγR3A polymorphism had better clinical response to avelumab., Conclusion: Our work demonstrates that antibody-dependent cell-mediated cytotoxicity contributes to the therapeutic effect of avelumab in gestational trophoblastic neoplasia and that the individual patient response is impacted by the FcγR3A polymorphism. The FcγR3A polymorphism could be used as a biomarker to identify patients diagnosed with monochemoresistant gestational trophoblastic neoplasia who are most likely to respond to avelumab., (Copyright © 2024 The Author(s).

- Abstract
Purpose: Toxic shock syndrome (TSS) is a rare disease responsible for significant morbidity and mortality. Intravenous immunoglobulin (IG) therapy in paediatric TSS could improve shock and organ failure, but more consistent efficacy and safety data are needed. Our objective was to determine whether a randomised clinical trial (RCT) assessing intravenous IG in TSS in children is feasible., Methods: We performed a multicentre, feasibility, double-blind RCT assessing efficacy of high-dose intravenous IG versus albumin 4% (control group) within the first 12 hours of shock onset. Included patients were aged above 1 month and below 18 years with suspected TSS and septic shock. Feasibility was assessed by measuring inclusion rate, protocol compliance and missing data regarding death and the Pediatric Logistic Organ Dysfunction-2 (PELOD-2) Score. Other secondary clinical outcomes were evaluated during hospital stay, at 60 day and 1 year., Results: 28 patients, admitted in 6 paediatric intensive care units during 36 consecutive months and followed for 1 year, received the allocated treatment: 13 in intravenous IG group, 15 in control group. The median age was 10.6 years and the sex ratio was 1. Inclusion rate was above 50%, protocol deviations were below 30% and missing data regarding death and PELOD-2 Score below 10%. No difference concerning secondary clinical outcomes between groups was observed, and more adverse events were reported in the control group., Conclusion: It seems to be feasible to conduct an RCT assessing intravenous IG efficacy and safety in paediatric TSS but must be realised internationally, with choice of a clinically relevant endpoint and a specific design in order to be realistic., Trial Registration Number: NCT02219165., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

- Abstract
Background: The immune response of critically ill patients, such as those with sepsis, severe trauma, or major surgery, is heterogeneous and dynamic, but its characterization and impact on outcomes are poorly understood. Until now, the primary challenge in advancing our understanding of the disease has been to concurrently address both multiparametric and temporal aspects., Methods: We used a clustering method to identify distinct groups of patients, based on various immune marker trajectories during the first week after admission to ICU. In 339 severely injured patients, we initially longitudinally clustered common biomarkers (both soluble and cellular parameters), whose variations are well-established during the immunosuppressive phase of sepsis. We then applied this multi-trajectory clustering using markers composed of whole blood immune-related mRNA., Results: We found that both sets of markers revealed two immunotypes, one of which was associated with worse outcomes, such as increased risk of hospital-acquired infection and mortality, and prolonged hospital stays. This immunotype showed signs of both hyperinflammation and immunosuppression, which persisted over time., Conclusion: Our study suggest that the immune system of critically ill patients can be characterized by two distinct longitudinal immunotypes, one of which included patients with a persistently dysregulated and impaired immune response. This work confirms the relevance of such methodology to stratify patients and pave the way for further studies using markers indicative of potential immunomodulatory drug targets., (© 2024.

- Abstract
Background: Invasive candidiasis is still recognized as a major cause of morbidity and mortality. To support clinicians in the optimal use of antifungals for the treatment of invasive candidiasis, a computerized decision support system (CDSS) was developed based on institutional guidelines., Objectives: To evaluate the correlation of this newly developed CDSS with clinical practices, we set-up a retrospective multicentre cohort study with the aim of providing the concordance rate between the CDSS recommendation and the medical prescription (NCT05656157)., Patients and Methods: Adult patients who received caspofungin or fluconazole for the treatment of an invasive candidiasis were included. The analysis of factors associated with concordance was performed using mixed logistic regression models with department as a random effect., Results: From March to November 2022, 190 patients were included from three centres and eight departments: 70 patients from centre A, 84 from centre B and 36 from centre C. Overall, 100 patients received caspofungin and 90 received fluconazole, mostly (59%; 112/190) for empirical/pre-emptive treatment. The overall percentage of concordance between the CDSS and medical prescriptions was 91% (173/190) (confidence interval 95%: 82%-96%). No significant difference in concordance was observed considering the centres (P > 0.99), the department of inclusion (P = 0.968), the antifungal treatment (P = 0.656) or the indication of treatment (P = 0.997). In most cases of discordance (n = 13/17, 76%), the CDSS recommended fluconazole whereas caspofungin was prescribed. The clinical usability evaluated by five clinicians was satisfactory., Conclusions: Our results demonstrated the high correlation between current antifungal clinical practice and this user-friendly and institutional guidelines-based CDSS., (© The Author(s) 2024.

- Abstract
Background: Based on preclinical studies showing that IDH-mutant (IDHm) gliomas could be vulnerable to PARP inhibition we launched a multicenter phase 2 study to test the efficacy of olaparib monotherapy in this population., Methods: Adults with recurrent IDHm high-grade gliomas (HGGs) after radiotherapy and at least one line of alkylating chemotherapy were enrolled. The primary endpoint was a 6-month progression-free survival rate (PFS-6) according to response assessment in neuro-oncology criteria. Pre-defined threshold for study success was a PFS-6 of at least 50%., Results: Thirty-five patients with recurrent IDHm HGGs were enrolled, 77% at ≥ 2nd recurrence. Median time since diagnosis and radiotherapy were 7.5 years and 33 months, respectively. PFS-6 was 31.4% (95% CI [16.9; 49.3%]). Two patients (6%) had an objective response and 14 patients (40%) had a stable disease as their best response. Median PFS and median overall survival were 2.05 and 15.9 months, respectively. Oligodendrogliomas (1p/19q codeleted) had a higher PFS-6 (53.4% vs. 15.7%, P = .05) than astrocytomas while an initial diagnosis of grade 4 astrocytoma tended to be associated with a lower PFS-6 compared to grade 2/3 gliomas (0% vs 31.4%, P = .16). A grade 2 or 3 treatment-related adverse event was observed in 15 patients (43%) and 5 patients (14%), respectively. No patient definitively discontinued treatment due to side effects., Conclusions: Although it did not meet its primary endpoint, the present study shows that in this heavily pretreated population, olaparib monotherapy was well tolerated and resulted in some activity, supporting further PARP inhibitors evaluation in IDHm HGGs, especially in oligodendrogliomas., Competing Interests: I.E.: none.

- Abstract
Background: Invasive aspergillosis (IA) is increasing especially in new groups of patients. Despite advances in management, morbidity and mortality related to IA remain high. Thus, Clinical Decision Support System (CDSS) dedicated to IA are needed to promote the optimal antifungal for each group of patients., Patients and Methods: This was a retrospective multicenter cohort study involving intensive care units and medical units. Adult patients who received caspofungin, isavuconazole, itraconazole, liposomal amphotericin B, posaconazole, or voriconazole, for the treatment of IA were eligible for enrollment. The primary objective was the concordance between the clinician's prescription and the prescription recommended by the CDSS. The secondary objective was the concordance according to different hospitals, departments, and indications., Results: Eighty-eight patients (n=88) from three medical hospitals were included. The overall concordance was 97% (85/88) including 100% (41/41) for center A, 92% (23/25) for center B, and 95% (21/22) for center C. There was no significant difference in concordance among the hospitals (P=0.973), the departments (P=1.000), and the indications (P=0.799). The concordance was 70% (7/10) for isavuconazole due to its use as an empirical treatment and 100% (78/78) for the other antifungals., Discussion: The concordance rate was high whatever the hospital, the department, and the indication. The only discrepancy was attributed to the use of isavuconazole as an empirical treatment which is a therapeutic option not included in the CDSS., Conclusions: This new CDSS dedicated to IA is meeting the clinical practice. Its implementation in routine will help to support antifungal stewardship., (Copyright © 2023 Académie Nationale de Pharmacie. Published by Elsevier Masson SAS. All rights reserved.)

- Abstract
Background: The multicentre randomised trial YOMEGA (NCT02139813) comparing the one anastomosis gastric bypass (OAGB) with the Roux-en-Y gastric bypass (RYGB) confirmed the non-inferiority of OAGB on weight loss outcomes at 24 months. We aimed to report weight loss, metabolic, and safety outcomes at 5 years., Methods: YOMEGA is a prospective, open-label, non-inferiority, randomised trial conducted at nine centres in France. Inclusion criteria were BMI of 40 kg/m
2 or more, or 35 kg/m2 or more with comorbidities. Key exclusion criteria were severe gastro-oesophageal reflux disease or Barrett's oesophagus and previous bariatric surgery. Patients were randomly assigned (1 :1) to OAGB (one gastrojejunal anastomosis with a 200 cm biliopancreatic limb) or RYGB (with a 150 cm alimentary limb and a 50 cm biliary limb), stratified by centre, with blocks of variable size. The primary endpoint of this extension study was percentage excess BMI loss and was analysed in the per-protocol population, including patients with data who were operated on with the technique randomly assigned to them and excluding patients with major deviations from the protocol during the follow-up (change of surgical technique, death, or withdrawal of consent). Non-inferiority was concluded for the primary endpoint if the upper bound of the CI was less than the non-inferiority limit (7 percentage points). YOMEGA is registered with ClinicalTrials.gov, NCT02139813, and the 5-year follow-up of YOMEGA is registered with ClinicalTrials.gov, NCT05549271., Findings: Between May 13, 2014, and March 2, 2016, 253 patients were randomly assigned to OAGB (n=129) or RYGB (n=124), and from these patients 114 in the OAGB group and 118 in the RYGB group were included in the per-protocol analysis. In the per-protocol population, at baseline, mean age was 43·0 years (SD 10·8), mean BMI was 44·0 kg/m2 (5·6), 54 (23%) patients were male and 178 (77%) were female; 55 (27%) of 207 patients had type 2 diabetes. After 5 years, mean percentage excess BMI loss was -75·6% (SD 28·1) in the OAGB group versus -71·4% (SD 29·8) in the RYGB group, confirming non-inferiority (mean difference -4·1% [90% CI -12·0 to 3·7], p=0·0099). Remission of type 2 diabetes was similar in both groups. Nutritional status did not differ; the most common adverse event was clinical gastro-oesophageal reflux disease, occurring in 27 (41%) of 66 patients in the OAGB group versus 14 (18%) of 76 patients in the RYGB group (p=0·0030). Among serious adverse events, ten (8%) of 127 patients converted from OAGB to RYGB. 171 (68%) of 253 patients were followed up., Interpretation: OAGB was not inferior to RYGB regarding percentage excess BMI loss at 5 years with similar metabolic outcomes. The high rate of clinical gastro-oesophageal reflux disease after OAGB raises questions about its long-term consequences, which need to be further investigated., Funding: Medtronic., Competing Interests: Declaration of interests TP reports fees for participation as an expert in a workshop organised by GORE and leadership in Bariatek board outside the submitted work.

- Abstract
Objectives: The objective of this study was to compare three different approaches for estimating 30-day survival in ICU studies, considering the issue of informative censoring that occurs when patients are lost to follow-up after discharge., Design: A comparative analysis was conducted to evaluate the effect of different approaches on the estimation of 30-day survival. Three methods were compared: the classical approach using the Kaplan-Meier (KM) estimator and Cox regression modeling, the competing risk approach using the Fine and gray model, considering censoring as a competing event, and the logistic regression approach., Setting: The study was conducted in a university ICU and data from patients admitted between 2010 and 2020 were included. Patient characteristics were collected from electronic records., Patients: A total of 10,581 patients were included in the study. The true date of death for each patient, obtained from a national registry, allowed for an absence of censoring., Interventions: All patients were censored at the time of discharge from the ICU, and the three different approaches were applied to estimate the mortality rate and the effects of covariates on mortality. Regression analyses were performed using five variables known to be associated with ICU mortality., Measurements and Main Results: The 30-day survival rate for the included patients was found to be 80.5% (95% CI, 79.7-81.2%). The KM estimator severely underestimated the 30-day survival (50.6%; 95% CI, 48.0-53.4%), while the competing risk and logistic regression approaches provided similar results, only slightly overestimating the survival rate (84.5%; 95% CI, 83.8-85.2%). Regression analyses showed that the estimates were not systematically biased, with the Cox and logistic regression models exhibiting greater bias compared with the competing risk regression method., Conclusions: The competing risk approach provides more accurate estimates of 30-day survival and is less biased compared with the other methods evaluated., Competing Interests: Dr. Friggeri received funding from Merck Sharp & Dohme. The remaining authors have disclosed that they do not have any potential conflicts of interest., (Copyright © 2023 by the Society of Critical Care Medicine and Wolters Kluwer Health, Inc.

45. An Overview of Regression Models for Adverse Events Analysis.
- Author

Coz E, Fauvernier M, and Maucort-Boulch D
- Abstract
Over the last few years, several review articles described the adverse events analysis as sub-optimal in clinical trials. Indeed, the context surrounding adverse events analyses often imply an overwhelming number of events, a lack of power to find associations, but also a lack of specific training regarding those complex data. In randomized controlled trials or in observational studies, comparing the occurrence of adverse events according to a covariable of interest (e.g., treatment) is a recurrent question in the analysis of drug safety data, and adjusting other important factors is often relevant. This article is an overview of the existing regression models that may be considered to compare adverse events and to discuss model choice regarding the characteristics of the adverse events of interest. Many dimensions may be relevant to compare the adverse events between patients, (e.g., timing, recurrence, and severity). Recent efforts have been made to cover all of them. For chronic treatments, the occurrence of intercurrent events during the patient follow-up usually needs the modeling approach to be adapted (at least with regard to their interpretation). Moreover, analysis based on regression models should not be limited to the estimation of relative effects. Indeed, absolute risks stemming from the model should be presented systematically to help the interpretation, to validate the model, and to encourage comparison of studies., (© 2023. The Author(s).)

- Abstract
Rhabdomyosarcoma (RMS) is the main form of pediatric soft-tissue sarcoma. Its cure rate has not notably improved in the last 20 years following relapse, and the lack of reliable preclinical models has hampered the design of new therapies. This is particularly true for highly heterogeneous fusion-negative RMS (FNRMS). Although methods have been proposed to establish FNRMS organoids, their efficiency remains limited to date, both in terms of derivation rate and ability to accurately mimic the original tumor. Here, we present the development of a next-generation 3D organoid model derived from relapsed adult and pediatric FNRMS. This model preserves the molecular features of the patients' tumors and is expandable for several months in 3D, reinforcing its interest to drug combination screening with longitudinal efficacy monitoring. As a proof-of-concept, we demonstrate its preclinical relevance by reevaluating the therapeutic opportunities of targeting apoptosis in FNRMS from a streamlined approach based on transcriptomic data exploitation., Competing Interests: Declaration of interests The Ecole Polytechnique Fédérale de Lausanne has filed for patent protection on technology used for the phenotypic drug screening performed on 3D organoid, and N.B. is named as an inventor on those patents; N.B is also shareholder in SUN bioscience SA and DOPPL SA, which are commercializing those patents., (Copyright © 2023 The Authors.

- Abstract
Purpose: Septic shock is associated in some patients with a profound immunosuppression. We hypothesized that GM-CSF would reduce the occurrence of ICU-acquired infections in immunosuppressed septic patients., Methods: Randomized double-blind trial conducted between 2015 and 2018. Adult patients, admitted to ICU, with severe sepsis or septic shock presenting with sepsis-induced immunosuppression defined by mHLA-DR < 8000 ABC (antibodies bound per cell) at day 3 were included. Patients were randomized to receive GM-CSF 125 μg/m
2 or placebo for 5 days at a 1:1 ratio. The primary outcome was the difference in the number of patients presenting≥1 ICU-acquired infection at day 28 or ICU discharge., Results: The study was prematurely stopped because of insufficient recruitment. A total of 98 patients were included, 54 in the intervention group and 44 in the placebo group. The two groups were similar except for a higher body mass index and McCabe score in the intervention group. No significant difference was observed between groups regarding ICU-acquired infection (11% vs 11%, p = 1.000), 28-day mortality (24% vs 27%,p = 0.900), or the number or localization of the ICU infections., Conclusion: GM-CSF had no effect on the prevention of ICU-acquired infection in sepsis immunosuppression, but any conclusion is limited by the early termination of the study leading to low number of included patients., Competing Interests: Declaration of Competing Interest None., (Copyright © 2023 Elsevier Inc.

- Abstract
Purpose: The COVID-19 pandemic has disrupted healthcare access and telemedicine has been widely deployed. The aim of this study is to assess the impact of this health crisis on treatment consumption and telemedicine development in outpatients treated by oral anti-cancer agents and followed by the Oncoral hospital/community multidisciplinary program where continuity care is maintained by a pharmacist/nurse pair., Methods: A prospective monocentric study was conducted among cancer patients who received Oncoral telephone follow-up during the 1st lockdown in France using a 56-item questionnaire which covered sociodemographic data, patient medication management, and telehealth., Results: 178 patients received Oncoral follow-up during the 1st lockdown and 67.4% responded to the questionnaire. During lockdown, 9.2% of patients took medication or CAM for fatigue, 6.7% for mood alteration, 10.8% for sleep disorder, 11.7% for stress and anxiety, and 12.5% to get more energy. Homeopathy consumption was triggered by the pandemic. Habits about getting drugs from the pharmacy changed significantly (p < 0.001), while other treatment habits did not. 83% of patients were satisfied by the telephone follow-up established, 69% would be in favor of repeating this in case of a new epidemic wave. Those most in favor of using telemedicine seemed to be the youngest (p < 0.001), with several dependent children (p < 0.007), high school degree or higher education (p = 0.023), and in work (p < 0.001)., Conclusion: Health system reorganization enables to limit the impact of the crisis on patients' drug use in oncology care. Telemedicine is a promising public health tool., (© 2023. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

- Abstract
Objective: The ProCCard study tested whether combining several cardioprotective interventions would reduce the myocardial and other biological and clinical damage in patients undergoing cardiac surgery., Design: Prospective, randomized, controlled trial., Setting: Multicenter tertiary care hospitals., Participants: 210 patients scheduled to undergo aortic valve surgery., Interventions: A control group (standard of care) was compared to a treated group combining five perioperative cardioprotective techniques: anesthesia with sevoflurane, remote ischemic preconditioning, close intraoperative blood glucose control, moderate respiratory acidosis (pH 7.30) just before aortic unclamping (concept of the "pH paradox"), and gentle reperfusion just after aortic unclamping., Measurements and Main Results: The primary outcome was the postoperative 72-h area under the curve (AUC) for high-sensitivity cardiac troponin I (hsTnI). Secondary endpoints were biological markers and clinical events occurring during the 30 postoperative days and the prespecified subgroup analyses. The linear relationship between the 72-h AUC for hsTnI and aortic clamping time, significant in both groups (p < 0.0001), was not modified by the treatment (p = 0.57). The rate of adverse events at 30 days was identical. A non-significant reduction of the 72-h AUC for hsTnI (-24%, p = 0.15) was observed when sevoflurane was administered during cardiopulmonary bypass (46% of patients in the treated group). The incidence of postoperative renal failure was not reduced (p = 0.104)., Conclusion: This multimodal cardioprotection has not demonstrated any biological or clinical benefit during cardiac surgery. The cardio- and reno-protective effects of sevoflurane and remote ischemic preconditioning therefore remain to be demonstrated in this context., Competing Interests: Conflicts of Interest None., (Copyright © 2023 Elsevier Inc.

- Abstract
Aims: Subclassification of large B cell lymphoma (LBCL) is challenging due to the overlap in histopathological, immunophenotypical and genetic data. In particular, the criteria to separate diffuse large B cell lymphoma (DLBCL) and high-grade B cell lymphoma (HGBL) are difficult to apply in practice. The Lunenburg Lymphoma Biomarker Consortium previously reported a cohort of over 5000 LBCL that included fluorescence in-situ hybridisation (FISH) data. This cohort contained 209 cases with MYC rearrangement that were available for a validation study by a panel of eight expert haematopathologists of how various histopathological features are used., Methods and Results: Digital whole slide images of haematoxylin and eosin-stained sections allowed the pathologists to visually score cases independently as well as participate in virtual joint review conferences. Standardised consensus guidelines were formulated for scoring histopathological features and included overall architecture/growth pattern, presence or absence of a starry-sky pattern, cell size, nuclear pleomorphism, nucleolar prominence and a range of cytological characteristics. Despite the use of consensus guidelines, the results show a high degree of discordance among the eight expert pathologists. Approximately 50% of the cases lacked a majority score, and this discordance spanned all six histopathological features. Moreover, none of the histological variables aided in prediction of MYC single versus double/triple-hit or immunoglobulin-partner FISH-based designations or clinical outcome measures., Conclusions: Our findings indicate that there are no specific conventional morphological parameters that help to subclassify MYC-rearranged LBCL or select cases for FISH analysis, and that incorporation of FISH data is essential for accurate classification and prognostication., (© 2023 The Authors.
