Abstract
BACKGROUND Patients with glioblastomas have a dismal prognosis, and there is no circulating predictive or prognostic biomarker. Circulating progastrin, hPG80, is a tumor-promoting peptide present in the blood of patients with various cancers that has been shown to have prognostic value. We evaluated the prognostic value of plasma hPG80 in patients with isocitrate dehydrogenase-wild type glioblastoma after surgery. PATIENTS AND METHODS A multicentric retrospective study in glioblastoma patients treated with standard radio-chemotherapy was conducted. The hPG80 levels were measured in plasma EDTA samples collected after surgery with an ELISA DxPG80.lab kit (Biodena Care, Montpellier, France), which has a detection threshold of 1.2 pM. The relationship between post-operative hPG80 plasma levels, in combination with other known prognostic factors, and patients' progression-free survival (PFS) and overall survival (OS) was evaluated. RESULTS Sixty-nine patients were assessable. Plasma samples were collected after tumor biopsy (B), partial resection (PR), and complete resection (CR) for 22, 25, and 22 patients, respectively. At a median concentration of 5.37 pM (interquartile range 0.00-13.90 pM), hPG80 was detected in 48 (70%) patients (hPG80+). CR was associated with significant lower values of hPG80 levels: the median value was 0.7 versus 9.1 pM for PR (P = 0.02) and 8.3 pM for B (P = 0.004). The hPG80 detection rate was also significantly lower: 50% (CR) versus 72% (PR) versus 86% (B) (P = 0.005). The median follow-up was 39 months [22.4 months-not reached]. hPG80 post-operative detection was associated with numerically shorter PFS (6.4 versus 9.4 months, P = 0.13) and OS (14.5 versus 20.9 months, P = 0.11). In multivariate analysis, hPG80 was a prognostic factor for OS (P = 0.034). CONCLUSIONS Circulating hPG80 could serve as a new prognostic biomarker after surgery in patients with glioblastoma treated with radio-chemotherapy.

Abstract
BACKGROUND Investigation of the disparities in the access to experimental treatment in early-phase clinical trials is lacking. The objective of the EGALICAN-2 study was to identify the factors underpinning such inequalities. METHODS A national prospective survey was conducted in 11 early-phase clinical trial centers (CLIP2) certified by the French National Cancer Institute. Sociodemographic, socioeconomic and medical data were collected. Univariate logistic regression models were carried out to estimate odds ratios and 90% confidence intervals associated with the effect of each study variable. A multivariate logistic regression model was built to explore the independent factors associated with the administration of the experimental treatment (C1D1). A post hoc analysis was carried out excluding female cancer patients. RESULTS Between 2015 and 2016, 1355 patients referred from 11 CLIP2 centers in France were included in the study. Eight hundred and forty-eight patients received C1D1 (73%) and 320 patients (27%) were screening failure. Median age was 58 years (range 17-97 years) and 667 patients (54%) were female. Most patients had a metastatic disease (n = 751, 87%). In the multivariate logistic regression analysis, the significant independent factors associated with C1D1 were male sex, initial care received in a hospital with an early-phase unit and living in wealthy metropolitan areas (P values <0.05). In the post hoc analysis, the sex factor was no longer significant [odds ratio = 1.21 (95% confidence interval 0.86-1.70), P value = 0.271]. CONCLUSIONS This study investigated the factors producing social inequalities in the context of early-phase clinical trials in oncology. Our research highlights factors of sex, care pathway and geographic location. Gynecological cancer was found to impact C1D1 significantly, unlike breast cancer. The results of this study should contribute to improve patient access to early-phase clinical trials.

Abstract
Septic arthritis is a diagnostic emergency. The white blood cell (WBC) count, in synovial fluid (SF), can guide the diagnosis. From November 2021 to November 2022, we included 350 SF. The WBC count was performed with the Iris iQ® 200 compared with the manual method. Automated and manual counts displayed good correlation. However, a Bland Altman plot demonstrates a higher percentage difference at higher WBC counts. The use of Iris iQ® 200 for SF analysis enables a rapid and accurate assessment for WBC count. Its implementation would advantageously replace the long and tedious optical analysis in daily routine.

Abstract
The outcomes of bariatric surgery, while often impressive, are not universally satisfactory; they vary from patient to patient and from operation to operation. Between 20-30% of patients experience suboptimal weight loss or substantial weight regain early in their postoperative course. Confronted with this chronic disease, and given that failures are difficult to manage, it is essential to better characterize obesity preoperatively, considering other metrics beyond just the body mass index (BMI), to select the best candidates for surgery and optimize the benefit/risk ratio. Based on the data of the most recent studies on bariatric surgery, our objective is to identify the predictive factors of weight loss as well as the risk factors of failure. Our analysis indicates that the choice of the surgical technique, age, initial BMI, ethnic origin, the presence of eating disorders and metabolic factors all have an impact on weight-loss outcomes after bariatric surgery. Thus, it is of major importance to carefully select patients during a preoperative multidisciplinary discussion in order to optimize weight loss and metabolic outcomes.

Abstract
Stevens-Johnson Syndrome (SJS) and toxic epidermal necrolysis (TEN) are serious and rare diseases, most often drug-induced, and their incidence has been estimated at 6 cases/million/year in France. SJS and TEN belong to the same spectrum of disease known as epidermal necrolysis (EN). They are characterized by more or less extensive epidermal detachment, associated with mucous membrane involvement, and may be complicated during the acute phase by fatal multiorgan failure. SJS and TEN can lead to severe ophthalmologic sequelae. There are no recommendations for ocular management during the chronic phase. We conducted a national audit of current practice in the 11 sites of the French reference center for toxic bullous dermatoses and a review of the literature to establish therapeutic consensus guidelines. Ophthalmologists and dermatologists from the French reference center for epidermal necrolysis were asked to complete a questionnaire on management practices in the chronic phase of SJS/TEN. The survey focused on the presence of a referent ophthalmologist at the center, the use of local treatments (artificial tears, corticosteroid eye drops, antibiotic-corticosteroids, antiseptics, vitamin A ointment (VA), cyclosporine, tacrolimus), the management of trichiatic eyelashes, meibomian dysfunction, symblepharons, and corneal neovascularization, as well as the contactologic solutions implemented. Eleven ophthalmologists and 9 dermatologists from 9 of the 11 centers responded to the questionnaire. Based on questionnaire results, 10/11 ophthalmologists systematically prescribed preservative-free artificial tears, and 11/11 administered VA. Antiseptic or antibiotic eye drops or antibiotic-corticosteroid eye drops were recommended as needed by 8/11 and 7/11 ophthalmologists, respectively. In case of chronic inflammation, topical cyclosporine was consistently proposed by 11/11 ophthalmologists. The removal of trichiatic eyelashes was mainly performed by 10/11 ophthalmologists. Patients were referred to a reference center for fitting of scleral lenses (10/10,100%). Based on this practice audit and literature review, we propose an evaluation form to facilitate ophthalmic data collection in the chronic phase of EN and we also propose an algorithm for the ophthalmologic management of ocular sequelae.

Abstract
Duchenne muscular dystrophy (DMD) is a severe and progressive myopathy leading to motor and cardiorespiratory impairment. We analyzed samples from patients with DMD and a preclinical rat model of severe DMD and determined that compromised repair capacity of muscle stem cells in DMD is associated with early and progressive muscle stem cell senescence. We also found that extraocular muscles (EOMs), which are spared by the disease in patients, contain muscle stem cells with long-lasting regenerative potential. Using single-cell transcriptomics analysis of muscles from a rat model of DMD, we identified the gene encoding thyroid-stimulating hormone receptor (Tshr) as highly expressed in EOM stem cells. Further, TSHR activity was involved in preventing senescence. Forskolin, which activates signaling downstream of TSHR, was found to reduce senescence of skeletal muscle stem cells, increase stem cell regenerative potential, and promote myogenesis, thereby improving muscle function in DMD rats. These findings indicate that stimulation of adenylyl cyclase leads to muscle repair in DMD, potentially providing a therapeutic approach for patients with the disease.

Abstract
Back pain is prevalent among gymnast populations and extreme flexion or extension of the lumbar spine along with high ground reaction forces (GRFs) are known to increase intervertebral stress. The aim of this study was to determine which postures and dynamic conditions among common floor movements provide the greatest risk of injury in men's artistic gymnastics (MAG). For this purpose, lumbar spine curvatures, obtained through a full-body subject-specific kinematic model fed by motion capture data, and GRFs on feet and hands were compared between typical floor movements of MAG (pike jump, round off back handspring, front handspring, forward and backward tucked somersaults) performed by six adolescent gymnasts. The round off back handspring and the pike jump resulted respectively in the largest lumbar extension and flexion, and the forward tucked somersault take-off in the highest GRF. At ground impacts, the largest lumbar flexion was during the backward tucked somersault landing and only the back handspring hands ground contact phase led to lumbar extension. Such identification of high-risk conditions should enable better back pain management in gymnastics through more tailored training adaptations, particularly in case of pathologies or musculoskeletal specificities.

Abstract
Microglia, the brain-resident immune cells, are highly ramified with dynamic processes transiently contacting synapses. These contacts have been reported to be activity-dependent, but this has not been thoroughly studied yet, especially in physiological conditions. Here we investigate neuron-microglia contacts and microglia morphodynamics in mice in an activity-dependent context such as the vigilance states. We report that microglial morphodynamics and microglia-spine contacts are regulated by spontaneous and evoked neuronal activity. We also found that sleep modulates microglial morphodynamics through Cx3cr1 signaling. At the synaptic level, microglial processes are attracted towards active spines during wake, and this relationship is hindered during sleep. Finally, microglial contact increases spine activity, mainly during NREM sleep. Altogether, these results indicate that microglial function at synapses is dependent on neuronal activity and the vigilance states, providing evidence that microglia could be important for synaptic homeostasis and plasticity.

Abstract
The aim of this study was to provide insights into myocardial adaptation over time in myocyte injury caused by acute myocarditis with preserved ejection fraction. The effect of myocardial injury, as defined by the presence of late gadolinium enhancement (LGE), on the change of left ventricular (LV) segmental strain parameters was evaluated in a longitudinal analysis. Patients with a first episode of acute myocarditis were enrolled retrospectively. Peak radial (PRS), longitudinal (PLS) and circumferential (PCS) LV segmental strain values at baseline and at follow-up were computed using feature tracking cine cardiac magnetic resonance imaging. The change of segmental strain values in LGE positive (LGE+) and LGE negative (LGE-) segments was compared over a course of 89 ± 20 days. In 24 patients, 100 LGE+ segments and 284 LGE- segments were analysed. Between LGE+ and LGE- segments, significant differences were found for the change of segmental PCS (p < 0.001) and segmental PRS (p = 0.006). LGE + segments showed an increase in contractility, indicating recovery, and LGE- segments showed a decrease in contractility, indicating normalisation after a hypercontractile state or impairment of an initially normal contracting segment. No significant difference between LGE+ and LGE- segments was found for the change in segmental PLS. In the course of acute myocarditis with preserved ejection fraction, regional myocardial function adapts inversely in segments with and without LGE. As these effects seem to counterbalance each other, global functional parameters might be of limited use in monitoring functional recovery of these patients.

Abstract
Congenital aniridia is a rare panocular disease defined by a national diagnostic and care protocol (PNDS) validated by the HAS. In most cases, it is due to an abnormality in the PAX6 gene, located at 11p13. Aniridia is a potentially blinding autosomal dominant disease with high penetrance. The prevalence varies from 1/40,000 births to 1/96,000 births. Approximately one third of cases are sporadic. Ocular involvement includes complete or partial absence of iris tissue, corneal opacification with neovascularization, glaucoma, cataract, foveal hypoplasia, optic disc hypoplasia and ptosis. These ocular disorders coexist to varying degrees and progress with age. Congenital aniridia manifests in the first months of life as nystagmus, visual impairment and photophobia. A syndromic form such as WAGR syndrome, WAGRO syndrome (due to the risk of renal Wilms tumor) or Gillespie syndrome (cerebellar ataxia) must be ruled out. Systemic associations may include diabetes, due to expression of the PAX6 gene in the pancreas, as well as other extraocular manifestations. Initial assessment is best carried out in a referral center specialized in rare ophthalmologic diseases, with annual follow-up. The management of progressive ocular involvement must be both proactive and responsive, with medical and surgical management. Visual impairment and photophobia result in disability, leading to difficulties in mobility, movement, communication, learning, fine motor skills, and autonomy, with consequences in personal, school, professional, socio-cultural and athletic life. Medico-socio-educational care involves a multidisciplinary team. Disability rehabilitation must be implemented to prevent and limit situations of handicap in activities of daily living, relying on the Commission for the Rights and Autonomy of People with Disabilities (CDAPH) within the Departmental House of People with Disabilities (MDPH). The general practitioner coordinates multidisciplinary medical and paramedical care.

Abstract
BackgroundIdiopathic inflammatory myopathies (IIMs) constitute a group of acquired muscular diseases that occur during childhood and adulthood, exhibit a variety of phenotypes and are potentially life-threatening. IIM diagnosis considers clinical, serological, and histological data. Muscle pathological analysis of IIM patients gives relevant elements for the diagnosis (immune cell infiltrate, vascular and connective tissues, as well as myofiber morphology). Immunochemistry (IHC) labeling for major histocompatibility complex class I (MHC-I), and C5b9, that are negative in normal muscle, appeared of interest in IIM diagnosis and the understanding of IIM pathogenesis. In normal muscle, myofibers are negative for MHC-II IHC. Its interest in the neuropathological exam of IIM muscle remains to be better characterized.ObjectivesThis study aims to analyze the pattern of MHC-II expression in various IIMs.MethodsA historical cohort was designed using the MYOLYON register (IIM patients diagnosed between 2016 and 2020 at the University Hospital of Lyon, France). Inclusion criteria were IIM diagnosis that was established histologically and available frozen muscle samples for additional analyses. Exclusion criterium was any treatment before muscle biopsy. Demographical data and final diagnosis were collected retrospectively from medical records. A centralized, standardized, and blind analysis of muscle MHC-II immuno-staining was conducted to define the various patterns of MHC-II by myofibers and by capillaries. The study complied with ethical requirements.ResultsSeventy-three patients were included: 23 dermatomyositis (DM), 13 anti-synthetase syndrome (ASS), 13 immune-mediated necrotizing myopathies (IMNM), 13 inclusion body myositis (IBM), and 11 overlap myositis (OM). MHC-II immuno-staining of myofibers or capillaries was abnormal for 91.8% of the analyzed biopsies (Figure 1). The analysis of MHC-II myofiber immuno-staining revealed distinguishable patterns according to IIM subtype: the labeling was diffuse in IBM (69.2%, n=9/13), perifascicular in ASS (61.5%, n=8/13), and variable in OM (patchy for 27.3% n=3/11 or clustered for 36.4%, n=4/11). MHC-II immuno-staining was negative in IMNM (84.6%, n=11/13) and in DM (47.8%, n=11/23). DM exhibiting positive MHC-II myofibers (n=12) were associated with the presence of anti-TIF1γ, anti-NXP2 and anti-SAE auto antibodies (n=5, n=3 and n=2, respectively). Among the 12 patients, there were juvenile cases (n=5, 41.7%) or DM associated with ongoing neoplasia (n=4, 33.3%). Three main architectures were described for capillaries: giant, leaky and capillary dropout. Patterns of MHC-II positive capillaries were the following: DM was characterized by capillary dropout (68.2%), IMNM showed leaky capillaries (75.0%), IBM giant capillaries (66.7%), ASS exhibited both giant (61.5%) and/or leaky (58.3%) capillaries, while OM showed giant (63.6%) or/and leaky (80.0%) capillaries and capillaries dropout (60.0%).ConclusionThe present work establishes the usefulness of MHC-II immuno-staining for IIM diagnosis, and gives additional elements on the impairment of myofibers and capillaries in the various IIM subgroups. MHC-II expression is known to be induced by inflammatory cytokine such as interferon type II. This could be linked to myofiber and/or capillary impairment in some IIMs, such as IBM, ASS and OM. These results also support the implication of vasculopathy in IIM pathogenesis, with various structural and cellular consequences regarding the different subgroups. Finally, MHC-II immuno-staining in IIM muscle biopsies enables a foremost analysis of myofibers and capillaries, and represents an additional biomarker to distinguish IIM subgroups.References[1]De Bleecker, J.L. et al. 205th ENMC International Workshop: Pathology diagnosis of idiopathic inflammatory myopathies part II 28-30 March 2014, Naarden, The Netherlands.

Abstract
BackgroundImaging mass cytometry (IMC) is a high-plex imaging technique that incorporates flow cytometry principles while preserving the histological and architectural components of the tissue sample. Characterizing the entire cellular component of temporal artery (TA) in patients with giant cell arteritis (GCA) may provide clues towards novel diagnostic and therapeutic approaches.ObjectivesWe aimed at a comprehensive summary of the immune cells and pathways involved GCA by using IMC approach.MethodsTA samples from biopsy-proven GCA patients (n=2) and controls (CTLs, n=2) were analyzed using IMC with a panel of 15 staining antibodies.ResultsEleven cell populations were identified in arterial wall from GCA patients including both immune (CD20+ B cells, CD8+ T cells, CD4+ T cells, FOXP3+ Tregs, CD66b+ granulocytes, CD11b+ myeloid cells, CD14+ monocytes, CD68+ macrophages) and non-immune (aSMA+ smooth muscle cells, CD31+ endothelial cells, Vimentin+ fibroblasts) cells (Figure 1). The 3 layers (intima, media and adventitia) of the arterial wall was enriched by all the immune cell subsets in GCA except for granulocytes and myeloid cells. CD8+, CD4+ and FOXP3+ regulatory T cells were significantly increased in any layer of the TA. The proportion of B cells was also enhanced in both intima and adventitia and displayed a high level of Ki67 expression.Figure 1.Unbiased clustering of cellular infiltrate in temporal arteritis using Imaging Mass Cytometry.Heatmap of different cell type markers expressed by the 11 cell populations identified in the arterial wall of GCA patients: CD20+ B cells, CD8+ T cells, CD4+ T cells, FOXP3+ Tregs, CD66b+ granulocytes, CD11b+ myeloid cells, CD14+ monocytes, CD68+ macrophages, Vimentin+ fibroblasts, aSMA+ smooth muscle cells and CD31+ endothelial cells.

Abstract
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.

Abstract
BackgroundChronic recurrent multifocal osteomyelitis (CRMO) is a rare inflammatory disease of the skeleton characterized by chronic and recurrent episodes of osteo-articular inflammation. The median age of onset is 10 years old. Clinical manifestations include musculoskeletal symptoms that are well described (pain, tenderness, swelling). Sometimes, skin lesions or digestive manifestations occur. Whole body magnetic resonance imaging (MRI) is the gold standard for assessing the multifocal pattern of the CRMO. Treatment is still empirical and mainly relies on non-steroidal anti-inflammatory drugs (NSAIDs). Bisphosphonates and biologics are used as second-line treatments. To date, the focus has been set on bone involvement and very few data are available on extra-osseous manifestations in CRMO.ObjectivesThis study aims to further describe these extra-osseous clinical manifestations in CRMO.MethodsA historical cohort was designed using 61 CRMO patients at the Pediatric Rheumatology Department in a tertiary university hospital in Paris (Hôpital Bicêtre, France). All patients underwent a MRI that confirmed the diagnosis according to the criteria of Jansson. Skeletal involvement was characterized with 1/axial, 2/ peripheral, 3/ axial and peripheral lesions. Extra-osseous manifestations were divided into 1/ skin lesions, 2/ gastro-intestinal manifestations, 3/ enthesitis and 4/ others. Pain was evaluated thanks to the Visual Analog Scale (VAS, from 0 to 10). Treatments used were recorded. The study complied with ethical requirements.ResultsForty one patients were included in the study, with 31 females (75.6%). The mean ± SD age at onset was 79.1 ± 59.8 months, with a delay at diagnosis beyond six months (6.71 ± 6.96). Twenty-one patients had a familial history of inflammatory diseases (51.2%), with a majority of psoriasis or ankylosing spondylitis (n=13/21, 61.9%). At diagnosis, the level of pain was 5.71 ± 3.24. Eleven patients (42.3%) had blood inflammation. Bone lesions were reviewed thanks to whole body MRI: four patients had isolated axial involvement (10.0%), nine had peripheral involvement (22.5%) and 27 patients harbored both types of lesions (67.5%). The mean number of lesions was 6.65 ± 4.23. After 12 months of follow-up, all parameters regarding disease’s activity decreased (pain, blood inflammation, number of lesions). Regarding extra-osseous symptoms, fever occurred in seven patients (17.1%). Twenty-four patients had skin manifestations (58.5%) with palmoplantar lesions (n=3, 12.5%), acne (n=6, 25.0%), psoriasis (n=5, 20.8%) and aphthous (n=10, 41.7%). Four patients (9.76%) had gastro-intestinal symptoms and seven (17.1%) had enthesitis. One patient had uveitis. Almost all patients received NSAIDs (n=39/41, 95.1%) and half of the cohort were treated with bisphosphonates (n=21/41, 51.2%). Nine patients (22.0%) received biologics with a majority of TNF inhibitors. All patients that received TNF inhibitors had either a cutaneous involvement or digestive symptoms or enthesitis (Figure 1).ConclusionExtra-osseous manifestations have to be carefully searched in CRMO, especially in the presence of familial history of inflammatory diseases. While the severity of bone involvement can lead to use bisphosphonates, the introduction of biologics seems to rely on extra-osseous symptoms. These conclusions are drawn on a retrospective study and need to be confirmed in larger cohort.References[1]Wipff J, et al.

Abstract
Introduction et but de l’étude La propagation du coronavirus (COVID-19) a eue pour conséquence la mise en place de mesures strictes de confinement, ayant entraîné des changements dans les comportements alimentaires. Les traits psychologiques sont des déterminants bien connus du comportement alimentaire. L’objectif de cette étude était donc d’étudier les associations entre les traits psychologiques positifs et les changements dans le grignotage et la consommation de groupes alimentaires pendant la période du confinement. Méthodes En 2016, les niveaux d’optimisme, de résilience, d’estime de soi, de satisfaction de la vie, de pleine conscience et de maîtrise ont été mesurés chez 33 766 adultes de la cohorte NutriNet-Santé. Le grignotage et la consommation de groupes d’aliments ont été évalués en avril–mai 2020. L’association entre les traits psychologiques et les changements dans le grignotage et la consommation de groupes alimentaires a été évaluée à l’aide de régressions logistiques, ajustées sur les caractéristiques sociodémographiques et le mode de vie, l’anxiété et la symptomatologie dépressive. Résultats Les participants présentant des niveaux plus élevés d’optimisme, de résilience, d’estime de soi, de satisfaction de la vie, de pleine conscience ou de maîtrise étaient moins susceptibles d’avoir des changements dans leur comportement de grignotage et leur consommation de divers groupes alimentaires. Conclusion Les personnes présentant des niveaux de traits psychologiques plus élevés ont été moins affectées par le confinement en termes de comportement alimentaire, alors que les personnes ayant des niveaux plus faibles ont montré des changements favorables et défavorables dans leur comportement alimentaire global.

Abstract
Systemic diseases, which are in France mainly monitored in internal medicine, affect multiple organs or tissues. While cutaneous or articular manifestations are the most common, neurological involvement is often associated with severity. Diagnosis of peripheral (e.g, neuropathies) or central (e.g, myelitis) nervous disorders is quite easy through clinical examination and dedicated complementary tests. However, neuropsychological manifestations that affect cognition, including memory, attention, executive functions or reasoning, are difficult to diagnose, sometimes trivialized by practitioners. Their causes are often numerous and interrelated. Nevertheless, these cognitive manifestations are closely related to patients' quality of life, affecting their social life, family dynamics and professional integration but also the treatment adherence. The purpose of this review, focused on the example of systemic lupus erythematosus, is to raise awareness of cognitive dysfunction in systemic diseases including their management from diagnosis to treatments. The final aim is to go further into setting up research groups and care programs for patients with cognitive impairment followed in internal medicine.

Abstract
Abstract
BACKGROUND
Due to the risk of pseudo-progression, evaluating the response of such combined treatment with anti-PDL1 immunotherapy and hypofractionated stereotactic radiotherapy (hFSRT) in patients with recurrent glioblastoma (GBM) is difficult even with iRANO criteria. We aim to analyze multi-modal MRI radiomic features in recurrent GBM patients included in the phase I STERIMGLI (NCT02866747) clinical trial.
MATERIAL AND METHODS
In phase I trial STERIMGLI, six patients received hFSRT 24 Gy in 3 fractions of 8 Gy prescribed to the 80% covering isodose in combination with Durvalumab IV 1500mg the same day following the third fraction of radiation then every 4 weeks for a maximum of 12 months. All patients underwent multi-modal MRI acquisitions. Contrast-enhancement on post-gadolinium T1 MRI (Gd-T1) and hyper-T2 signal on FLAIR MRI were manually segmented as volume-of-interest (VOIs) from baseline at week 0 (W0) and every eight weeks until weeks sixteen (W16). For patient 05, segmentation was performed until progression (W40). First order radiomics were extracted and normalized from these longitudinal VOIs in a total of 42 MRI: volume (in cm3), mean and median intensity, entropy, skewness and kurtosis were computed for each VOI. In total 504 (2 x 42 x 6) features were extracted.
RESULTS
Two patients underwent pseudoprogression (patients 04 and 05).
All patients but one (patient 05) presented an early relapse with an increase of FLAIR and Gd-T1 volumes and respective entropies from the first evaluation without decrease during follow up (until W16).
Patient 05 presented a Dose Limiting Toxicities and had the longest time to progression after Durvalumab and hFSRT. Contrary to the other patients, his FLAIR radiomics features presented a decrease of volume, intensity and entropy between W0 and W16 then, interestingly an increase between W24 and W40, date of progression. Moreover, patient 05 presented the lowest tumor volume and the lowest Gd-T1entropy. The intensity of the Gd-T1 followed the same trend as the hyper intense signal on the FLAIR in all patients, in particular for patient 05.
CONCLUSION
In our study, entropy and tumor volume for both FLAIR and Gd-T1, and FLAIR intensity seems to be the most interesting parameters to access the response of combined treatment. FLAIR signal may be more specific to the tumor microenvironment.
First order radiomics allowed us to follow tumor heterogeneity and identify the patient with the longest time to progression.

Abstract
PURPOSE Gastropleural and gastrobronchial fistulas (GPF/GBFs) are serious but rare complications after bariatric surgery whose management is not consensual. The aim was to establish a cohort and evaluate different clinical presentations and therapeutic options. MATERIALS AND METHODS A multicenter and retrospective study analyzing GPF/GBFs after bariatric surgery in France between 2007 and 2018, via a questionnaire sent to digestive and thoracic surgery departments. RESULTS The study included 24 patients from 9 surgical departments after initial bariatric surgery (21 sleeve gastrectomies; 3 gastric bypass) for morbid obesity (mean BMI = 42 ± 8 kg/m2). The GPF/GBFs occurred, on average, 124 days after bariatric surgery, complicating an initial post-operative gastric fistula (POGF) in 66% of cases. Endoscopic digestive treatment was performed in 79% of cases (n = 19) associated in 25% of cases (n = 6) with thoracic endoscopy. Surgical treatment was performed in 83% of cases (n = 20): thoracic surgery (n = 5), digestive surgery (n = 8), and combined surgery (n = 7). No patient died. Overall morbidity was 42%. The overall success rate of the initial and secondary strategies was 58.5% and 90%, respectively. The average healing time was approximately 7 months. Patients who had undergone thoracic surgery (n = 12) had more initial management failures (n = 9/12) than patients who had not (n = 3/12), p = 0.001. CONCLUSION Complex and life-threatening fistulas that are revealed late require a multidisciplinary strategy. Thoracic surgery should be reserved once the abdominal leak heals; otherwise, it is associated with a higher risk of failure.

Abstract
With next generation sequencing, physicians are faced with more complex and uncertain data, particularly incidental findings (IF). Guidelines for the return of IF have been published by learned societies. However, little is known about how patients are affected by these results in a context of oncogenetic testing. Over 4 years, 2500 patients with an indication for genetic testing underwent a gene cancer panel. If an IF was detected, patients were contacted by a physician/genetic counsellor and invited to take part in a semi-structured interview to assess their understanding of the result, the change in medical care, the psychological impact, and the transmission of results to the family. Fourteen patients (0.56%) were delivered an IF in a cancer predisposition gene (RAD51C, PMS2, SDHC, RET, BRCA2, CHEK2, CDKN2A, CDH1, SUFU). Two patients did not collect the results and another two died before the return of results. Within the 10 patients recontacted, most of them reported surprise at the delivery of IF, but not anxiety. The majority felt they had chosen to obtain the result and enough information to understand it. They all initiated the recommended follow-up and did not regret the procedure. Information regarding the IF was transmitted to their offspring but siblings or second-degree relatives were not consistently informed. No major adverse psychological events were found in our experience. IF will be inherent to the development of sequencing, even for restricted gene panels, so it is important to increase our knowledge on the impact of such results in different contexts.

Abstract
Earth-abundant Fe, Ni, and Co aza macrocyclic and polypyridine complexes have been thoroughly investigated for CO2 electrochemical and visible-light-driven reduction. Since the first reports in the 1970s, an enormous body of work has been accumulated regarding the two-electron two-proton reduction of the gas, along with mechanistic and spectroscopic efforts to rationalize the reactivity and establish guidelines for structure-reactivity relationships. The ability to fine tune the ligand structure and the almost unlimited possibilities of designing new complexes have led to highly selective and efficient catalysts. Recent efforts toward developing hybrid systems upon combining molecular catalysts with conductive or semi-conductive materials have converged to high catalytic performances in water solutions, to the inclusion of these catalysts into CO2 electrolyzers and photo-electrochemical devices, and to the discovery of catalytic pathways beyond two electrons. Combined with the continuous mechanistic efforts and new developments for in situ and in operando spectroscopic studies, molecular catalysis of CO2 reduction remains a highly creative approach.

Abstract
The increasing number of frail elderly people in our aging society is becoming problematic: about 11% of community‐dwelling older persons are frail and another 42% are pre‐frail. Consequently, a major challenge in the coming years will be to test people over the age of 60 years to detect pre‐frailty at the earliest stage and to return them to robustness using the targeted interventions that are becoming increasingly available. This challenge requires individual longitudinal monitoring (ILM) or follow‐up of community‐dwelling older persons using quantitative approaches. This paper briefly describes an effort to tackle this challenge. Extending the detection of the pre‐frail stages to other population groups is also suggested. Appropriate algorithms have been used to begin the tracing of faint physiological signals in order to detect transitions from robustness to pre‐frailty states and from pre‐frailty to frailty states. It is hoped that these studies will allow older adults to receive preventive treatment at the correct institutions and by the appropriate professionals as early as possible, which will prevent loss of autonomy. Altogether, ILM is conceived as an emerging property of databases (“digital twins”) and not the reverse. Furthermore, ILM should facilitate a coordinated set of actions by the caregivers, which is a complex challenge in itself. This approach should be gradually extended to all ages, because frailty has no age, as is testified by overwork, burnout, and post‐traumatic syndrome.

Abstract
Aims: To compare the effects of intrathecal anaesthesia using procaine and xylazine, with and without sedation with I/V xylazine and butorphanol, on sedation and cardiorespiratory measures in calves undergoing umbilical surgery. Methods: Male dairy calves, aged <3 months, were recruited that had enlargement of the umbilical stalk which was abnormal when palpated. They were assigned to receive either intrathecal injection between the sixth lumbar and first sacral vertebrae of 4 mg/kg of 2% procaine and 0.2 mg/kg 2% xylazine, with I/V injection of 0.02 mg/kg xylazine and 0.1 mg/kg of butorphanol (IT + SED group; n = 6), or the same intrathecal injection and I/V injection of 0.9% saline (IT group; n = 7). Surgery to correct abnormalities was carried out with calves positioned in dorsal recumbency. Rescue analgesia with injections of 2% procaine around the surgical wound was administered when movements triggered by surgery were observed. Post-operative analgesia was provided using I/V 0.5 mg/kg meloxicam. Duration of surgery was recorded, as well as degree of sedation, heart rate, systolic (SAP), diastolic (DAP) and mean (MAP) arterial blood pressure during surgery. Results: All anaesthetic and surgical procedures were successfully performed. Mean total duration of surgery was similar for the IT + SED and the IT groups (30.33 (SD 10.09) and 31.00 (SD 10.21) minutes, respectively) (p = 0.92). All calves were at least mildly sedated from 5 minutes after injections to the end of the surgery. One calf in the IT + SED group and three calves in the IT group required rescue analgesia when the umbilicus was manipulated. Between 0 and 10-15 minutes after injection, decreases in mean heart rate, SAP, MAP and DAP were observed in both groups. Mean SAP was lower in the IT + SED than the IT group. Hypotension (MAP<60 mm Hg) was present in four calves from the IT + SED group and in one from the IT group. Conclusions and clinical relevance: Intrathecal administration of 2% procaine and 2% xylazine allowed the successful completion of umbilical surgery, but 30% of calves needed rescue analgesia during surgery. Clinically, the addition of I/V sedation seemed to provide better analgesia than intrathecal block alone but resulted in greater hypotension.

Abstract
The involvement of the interleukin (IL)-17 axis in many inflammatory and autoimmune diseases is now well established, and this has led to the development of successful targeted therapies. Its role in systemic lupus erythematosus (SLE) is less described, since SLE is characterized by the impairment of many other immune actors. However, results from animal models and patients strongly suggest that IL-17 and its producing cells are involved in SLE pathogenesis. Circulating levels of IL-17 are increased in lupus, and tissue staining shows the presence of IL-17-producing cells in organ lesions. Through different mechanisms, the IL-17 axis promotes autoantibody production, immune complex deposition, complement activation and then tissue damage. There are also many interactions with other immune and non-immune actors, which account for the broad spectrum of clinical manifestations and disease heterogeneity. SLE treatment faces challenges with many disappointing trials and persistent unmet needs. The identification of subsets of SLE patients with an IL-17-driven disease now constitutes the key priority before starting trials. More preclinical studies are needed to improve the selection of the right patients able to respond and tolerate the many inhibitors that are already available.

Abstract
Abstract
Background
French employees receive compensations for diseases officially recognized as professionnal disease. Reimbursment data are thus used to produce statistics. Such data do not integrate uncompensated work-related diseases (UUWRD) defined as likely to be of occupational origin but not recognized as well. In 2003, the National Public Health Agency implemented a surveillance program on UWRD. This program is a complement to the compensation system for occupational diseases.
This communication presents results UWRD program can provide.
Methods
Twice a year, a network of volunteer occupational physicians (OP) reports ill health and associated work exposures of employees. Employee sociodemographics are notified. In 2018, half of French regions are integrated in the program.
Prevalence rates are calculated for UWRD. Chi-squared tests are used to compare prevalence rates between groups. Multivariate logistic regressions are conducted to evaluate:1- risks to report UWRD between groups, 2- prevalence rates trends. Underreporting rates of UWRD are approximated using an indicator capturing differences between figures produced by UWRD program and the compensation system.
Results
Over the 2009-2014 period, women working in mass food retail were observed at higher risk to present musuculoskeletical disorders than women of other sectors (ORa = 2.0). Same results were noted for men (ORa = 1.3). In mass food retail, decreases in musculoskeletal disorder prevalence rates were reported. Estimated average annual change rates were of 7.0 % for women and 11.0% for men. In 2011, UWRD data highlighted that between half and three-quarter of work-related musculoskeletal disorders were unreported by the compensation system.
Conclusions
UWRD data are used to identify vulnerable groups, analyse temporal trends and evaluate underreporting of professionnal disease.
Key messages
URWD program is a complement to the compensation system and let to better monitor health status of communities. Such informations are of interest to guide prevention policies.
