Abstract: International audience; Objective: To explore the regulatory role of soluble CD146 (sCD146) and its interaction with galectin-1 (Gal1) in placenta-mediated complications of pregnancy.Design: Prospective pilot and experimental studies.Setting: University-affiliated hospital and academic research laboratory.Patient(s): One hundred fifteen women divided into three groups: 30 healthy, nonpregnant women, 50 women with normal pregnancies, and 35 with placenta-mediated pregnancy complications.Intervention(s): Wound-healing experiments were conducted to study trophoblast migration.Main outcome measure(s): Quantification of sCD146 and Gal1 by enzyme-linked immunosorbent assay. Analysis of trophoblast migration by wound closure.Result(s): Concomitant detection of sCD146 and Gal1 showed lower sCD146 and higher Gal1 concentrations in women with normal pregnancies compared with nonpregnant women. In addition, follow-up of these women revealed a decrease in sCD146 associated with an increase in Gal1 throughout pregnancy. In contrast, in women with preeclampsia, we found significantly higher sCD146 concentrations compared with women with normal pregnancies and no modification of Gal1. We emphasize the opposing effects of sCD146 and Gal, since, unlike Gal1, sCD146 inhibits trophoblast migration. Moreover, the migratory effect of Gal1 was abrogated with the use of an anti-CD146 blocking antibody or the use of small interfering RNA to silence VEGFR2 expression. This suggests that trophoblast migration is mediated though the interaction of Gal1 with CD146, further activating the VEGFR2 signaling pathway. Significantly, sCD146 blocked the migratory effects of Gal1 on trophoblasts and inhibited its secretion, suggesting that sCD146 acts as a ligand trap.Conclusion(s): Soluble CD146 could be proposed as a biomarker in preeclampsia and a potential therapeutic target.

Abstract: Background: This prospective multicentre pilot study of patients scheduled for elective major abdominal surgery aimed to validate the fluid challenge (FC) proposed by the closed-loop (CL) system via anaesthesiologist assessment. Methods: This was a phase II trial consisting of two inclusion stages (SIMON method). Each FC (250 mL saline solution for 10 min) proposed by the CL was systematically validated by the anaesthesiologist who could either confirm or refuse the FC or give FC without the CL system. A ≥ 95% agreement between the CL and the anaesthesiologist was considered acceptable. Results: The study was interrupted after interim analysis of the first 19 patients (10 men, median age = 61 years, median body mass index = 26 kg/m2). The anaesthesiologists accepted 165/205 (80%) of fluid boluses proposed by the CL. Median cardiac index (CI) was 2.9 (interquartile: IQ (2.7; 3.4) L/min/m2) and the median coefficient of variation (CV) for CI was 13% (10; 17). Fifteen out of nineteen patients (79%) had a mean CI > 2.5 L/min/m2 or spent > 85% surgery time with pulse pressure variation < 13%. No adverse events related to the CL were reported. Conclusion: In this study of patients scheduled for elective major abdominal surgery, the agreement between CL and anaesthesiologist for giving fluid challenge was 80%, suggesting that CL cannot replace the physician but could help in decision making.

Abstract: International audience; Background: Preterm birth is a major cause of morbidity and mortality in infants and children. Non-invasive methods for screening the neonatal immune status are lacking. Archaea, a prokaryotic life domain, comprise methanogenic species that are part of the neonatal human microbiota and contribute to early immune imprinting. However, they have not yet been characterized in preterm neonates. Objective: To characterize the gut immunological and methanogenic Archaeal (MA) signature in preterm neonates, using the presence or absence of atopic conditions at the age of one year as a clinical endpoint. Methods: Meconium and stool were collected from preterm neonates and used to develop a standardized stool preparation method for the assessment of mediators and cytokines and characterize the qPCR kinetics of gut MA. Analysis addressed the relationship between immunological biomarkers, Archaea abundance, and atopic disease at age one. Results: Immunoglobulin E, tryptase, calprotectin, EDN, cytokines, and MA were detectable in the meconium and later samples. Atopic conditions at age of one year were positively associated with neonatal EDN, IL-1β, IL-10, IL-6, and MA abundance. The latter was negatively associated with neonatal EDN, IL-1β, and IL-6. Conclusions: We report a non-invasive method for establishing a gut immunological and Archaeal signature in preterm neonates, predictive of atopic diseases at the age of one year.

Abstract: International audience; The ideal treatment for multiple sclerosis (MS) would target both the neuroinflammatory component of the disease (peripheral and central) and its neurodegenerative component, via modulation of a ubiquitous and pleiotropic common target. Sphingosine-1-phosphate (S1P), a product of sphingosine metabolism, regulates many biological functions (including cell proliferation and survival, cell migration, the immune response and cardiovascular function) via five subtypes of receptor. These receptors are expressed in all types of brain cells where they modulate a number of processes involved in neuronal plasticity, including myelination, neurogenesis and neuroprotection. This profile has aroused interest in modulation of S1P function as a therapeutic target in many brain diseases, particularly those in which the immune system plays a role in the development of brain lesions. Fingolimod, a S1P receptor modulator, exerts its beneficial effects in MS through its anti-inflammatory and anti-neurodegenerative effects. This review discusses recent evidence indicating that fingolimod may target both the inflammatory and neurodegenerative components of the disease process in MS.

Abstract: International audience; Background: In the current context of climate change, actions must be taken to improve the hospital's ecological footprint, particularly in the operating room, which is a major consumer of medical devices.Methods: This prospective pilot study assessed the ecological and economic impacts of sustainable actions targeting medical devices designed by a multidisciplinary working group and implemented in the 24 operating rooms of a University Hospital over one year. The ecological analysis was based on the life cycle assessment method and categorized in seven impacts. The economic impact was assessed by a micro-costing analysis and divided in four main expense items: human and material resources, logistics, and waste management.Results: In total, 13 actions were implemented with the aim of reducing waste volume, improving waste sorting, and increasing eco-responsible purchases. In one year, these 13 actions allowed avoiding the emission of 203 tons eq CO2. The environmental and human toxicity benefits were 707.8 and 156.2 tons of 1.4 dichlorobenzene, respectively. Concerning non-renewable resources, these actions avoided the extraction of 9 tons of oil (petroleum) and 610 kg of copper per year. These actions led to a land occupation reduction of 1071.3 m2year and to water saving of 552 m3. From the economic side, the implementation of these actions brought a gain of €3747.9 for the first year and of €5188.2 for the following years.Conclusion: The integration of sustainable measures in operating rooms leads to important ecological benefits and also generating savings. This more eco-responsible approach should be considered in all healthcare establishments that generate a significant annual volume of waste.

Abstract: International audience; Background: A detailed quantitative evaluation would be beneficial for management of patients with limb lymphedema. Methods and Results: In 47 patients with lower limb lymphedema at International Society of Lymphology clinical stage 2A (18 limbs), 2B (41 limbs), and 3 (13 limbs), we measured the limb circumference and thickness of epidermis, dermis, and subcutis layers with B-mode ultrasonography and subcutis elastic modulus with ultrafast shear wave velocity (ultrasound elastography) at 5 anatomical levels (M1 to M5) before and after a 3- to 5-day intensive decongestive therapy (IDT) session. Limb circumference and thickness of the epidermis, dermis, and subcutis were greater in the 72 limbs with lymphedema than in the 22 unaffected limbs before and after IDT. The affected limb volume was 10,980 [8458-13,960] mL before and 9607 [7720-11,830] mL after IDT (p

Abstract: International audience; Objective: The primary endpoint of this meta-analysis was the PSH rate at 1 year of follow-up with or without the use of a mesh.Summary of background data: European guidelines currently recommend the use of a mesh at the time of a stoma formation for the prevention of PSH. These recommendations are based on the RCT and meta-analyses published before 2017. More recently 2 large RCT found no benefit in the mesh group. We investigated whether these latest results could change the conclusion of a meta-analysis.Methods: We conducted a comprehensive literature search and analyzed RCT investigating the use of a mesh to prevent PSH formation. All studies including end colostomies were included in the qualitative analysis no matter the surgical technique or the type of mesh. All studies with a limited risk of bias and presenting with usable data were used in the quantitative analysis.Results: There is a large heterogeneity among the studies, in terms of position of the mesh, surgical technique, and diagnostic method for the PSH. No statistically significant difference was found on the PSH rate at 1 or 2 years between the mesh and non-mesh groups.Conclusions: Based on this meta-analysis including the latest RCT on the prevention of PSH, the use of a mesh should not be recommended.

Abstract: TeleDiab‐2 was a 13‐month randomized controlled trial evaluating the efficacy and safety of two telemonitoring systems to optimize basal insulin (BI) initiation in subjects with inadequately controlled type 2 diabetes (HbA1c, 7.5%‐10%). A total of 191 participants (mean age 58.7 years, mean HbA1c 8.9%) were randomized into three groups: group 1(G1, standard care, n = 63), group 2 (G2, interactive voice response system, n = 64) and group 3 (G3, Diabeo‐BI app software, n = 64). The two telemonitoring systems proposed daily adjustments of BI doses, in order to facilitate the achievement of fasting blood glucose (FBG) values targeted at ~100 mg/dL. At 4 months follow‐up, HbA1c reduction was significantly higher in the telemonitoring groups (G2: −1.44% and G3: −1.48% vs. G1: −0.92%; P

Abstract: Chronic low back pain (cLBP) affects a quarter of a population during its lifetime. The most severe cases include patients not responding to interventions such as 5-week-long in-hospital multi-disciplinary protocols. This document reports on a pilot study offering an alpha-phase synchronization (APS) brain rehabilitation intervention to a population of n = 16 multi-resistant cLBP patients. The intervention consists of 20 sessions of highly controlled electroencephalography (EEG) APS operant conditioning (neurofeedback) paradigm delivered in the form of visual feedback. Visual analogue scale for pain, Dallas, Hamilton, and HAD were measured before, after, at 6-month and 12-month follow-up. Full-scalp EEG data were analyzed to study significant changes in the brain’s electrical activity. The intervention showed a great and lasting response of most measured clinical scales. The clinical improvement was lasting beyond the 6-month follow-up endpoints. The EEG data confirm that patients did control (intra-session trends) and learned to better control (intersession trends) their APS neuromarker resulting in (nonsignificant) baseline changes in their resting state activity. Last and most significantly, the alpha-phase concentration (APC) neuromarker, specific to phase rather than amplitude, was found to correlate significantly with the reduction in clinical symptoms in a typical dose–response effect. This first experiment highlights the role of the APC neuromarker in relation to the nucleus accumbens activity and its role on nociception and the chronicity of pain. This study suggests APC rehabilitation could be used clinically for the most severe cases of cLBP. Its excellent safety profile and availability as a home-use intervention makes it a potentially disruptive tool in the context of nonsteroidal anti-inflammatory drugs and opioid abuses.

Abstract: [Aim] This study analyzed the virulence of several Acinetobacter baumannii strains expressing different resistance mechanisms using the Caenorhabditis elegans infection model., [Results] Strains susceptible/resistant to carbapenems (presenting class D (OXA-23, OXA-24), class B metallo-β-lactamase (MBL) (NDM-1), penicillin binding protein (PBP) altered and decreased expression of Omp 33–36 kDa) and isogenic A. baumannii strains susceptible/resistant to colistin (presenting loss of lipopolysaccharide (LPS) and pmrA mutations) were included to evaluate the virulence using the C. elegans infection model. The nematode killing assay, bacterial ingestion in worms, and bacterial lawn avoidance assay were performed with the Fer-15 mutant line. A. baumannii strains generally presented low virulence, showing no difference between carbapenem-resistant strains (expressing class D, MBLs, or altered PBP) and their isogenic susceptible strains. In contrast, the absence of the Omp 33–36 kDa protein in the knockout was associated with a decrease of virulence, and a significant difference was observed between colistin-resistant mutants and their susceptible counterpart when the mechanism of resistance was associated with the loss of LPS but not with its modification., [Conclusions] Resistance to carbapenems in A. baumannii associated with the production of OXA-type or NDM-type enzymes does not seem to affect their virulence in the C. elegans infection model. In contrast, the presence of Omp 33–36 kDa, and high level resistance to colistin related with the loss of LPS, might contribute with the virulence profile in A. baumannii., This work was supported by INSERM, the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) under Research Grant (2013) to PE, the Spanish Society of Clinical Microbiology and Infectious Diseases (SEIMC) under travel grant to PE, and the Instituto de Salud Carlos III (ISCIII), Madrid, Spain under “Sara Borrell” Postdoctoral Contract CD12/00482 to DR and CD15/00017 to PE.

Abstract: International audience; Malignancies can be associated with positive antiphospholipid antibodies but the incidence of cancer among women with the purely obstetric form of antiphospholipid syndrome (APS) is currently unknown. Our aim was to investigate the comparative incidence of cancers in women with a history of obstetric APS within a referral university hospital-based cohort (NOH-APS cohort). We performed a 17-year observational study of 1,592 non-thrombotic women with three consecutive spontaneous abortions before the 10th week of gestation or one fetal death at or beyond the 10th week of gestation. We compared the incidence of cancer diagnosis during follow-up among the cohort of women positive for antiphospholipid antibodies (n=517), the cohort of women carrying the F5 rs6025 or F2 rs1799963 polymorphism (n=279) and a cohort of women with negative thrombophilia screening results (n=796). The annualized rate of cancer was 0.300% (0.20%-0.44%) for women with obstetric APS and their cancer risk was substantially higher than that of women with negative thrombophilia screening [adjusted hazard ratio (aHR) 2.483; 95% confidence interval (CI) 1.27-4.85]. The computed standardized incidence ratio for women with obstetric APS was 2.89; 95% CI: 1.89-4.23. Among antiphospholipid antibodies, lupus anticoagulant was associated with incident cancers (aHR 2.608; 95% CI: 1.091-6.236). Our cohort study shows that the risk of cancer is substantially higher in women with a history of obstetric APS than in the general population, and in women with a similar initial clinical history but negative for antiphospholipid antibodies.

Abstract: The diagnosis of atypical inflammatory demyelinating lesions can be difficult. Brain biopsy is often required to exclude neoplasms. Moreover, the relationship between these lesions and multiple sclerosis and NMOSD is not clear. Our objectives were to describe radiological and pathological characteristics of patients with acute inflammatory demyelinating lesions. We retrospectively identified patients with brain biopsy performed for diagnostic uncertainty revealing a demyelinating lesion. A complete clinical, biological, radiological and pathological analysis was performed. Twenty patients (15 with a single lesion) were included. MRI disclosed a wide range of lesions including infiltrative lesions (40%), ring-like lesion (15%) Balo-like lesion (15%) and acute haemorrhagic leukoencephalitis (20%). In spite of a marked heterogeneity, some findings were common: a peripheral B1000 hyperintense rim (70%), a slight oedema with mild mass effect (75%) and an open-rim peripheral enhancement (75%). Histopathology revealed that all cases featured macrophages distributed throughout, extensive demyelination, axonal preservation and absence of haemorrhagic changes. In the majority of cases, macrophages were the predominant inflammatory infiltrate and astrocytes were reactive and dystrophic. Aquaporin-4 staining was systematically preserved. After a mean follow-up of 5 years (1–12), 16/20 patients had a diagnosis of monophasic acute atypical inflammatory demyelinating lesion. One patient was diagnosed with MS and 3 with AQP4 negative NMOSD. Although imaging findings in patients with atypical inflammatory demyelinating lesions are heterogeneous, some common features such as peripheral DWI hyperintense rim with open-rim enhancement and absence of oedema argue in favour of a demyelinating lesion and should preclude a brain biopsy. In this context, AQP4 staining is systematically preserved and argues against an AQP4-positive NMOSD. Moreover, long-term follow-up is characterized by low recurrence rate.

Abstract: International audience; Objectives - Time to blood culture positivity (TTP), a routinely available parameter in automated blood culture systems, may be a proxy for infectious burden in patients with bloodstream infections. We aimed to study the association between TTP and infective endocarditis (IE), or death, in patients with Staphylococcus aureus bacteraemia. Methods - VIRSTA is a multicenter prospective cohort study that included all adult patients with S. aureus bacteraemia in eight university hospitals in France (2009-2011). We analyzed data from four centers which collected data on TTP. Regression models were used to study the association between TTP and definite IE (Duke-Li criteria), and 30 day-mortality. Results - We included 587 patients with S. aureus bacteraemia: mean age was 65.3±16.3 years, 420/587 patients (71.6%) were male, 121/587 (20.6%) died, and 42/587 (7.2%) had definite IE. Median TTP of first positive blood culture was 13.7 h (interquartile range, 9.9-18). On multivariate analysis, 30-day mortality was associated with TTP≤13.7 h (74/295 (25.1%) vs 47/292 (16.1%), P=0.02), as well as old age, McCabe score, methicillin resistance, stroke, pneumonia, and C-Reactive Protein. TTP was also independently associated with IE, but with a U-shape curve: IE was more common in the first (TTP18 h, 8/146, 5.5%) quartiles of TTP, P=0.002. Conclusions - TTP provides reliable information in patients with S. aureus bacteraemia, on the risk of IE, and prognosis, with short TTP being an independent predictor of death. This data readily available at no cost may be used to identify patients who require specific attention.

Abstract: OBJECTIVE: To analyze whether myelin oligodendrocyte glycoprotein antibody (MOG-Ab) titres at onset of the disease were different according to the clinical phenotype at presentation, and to investigate whether the titres were associated with risk of further relapses or predicted clinical outcome in adult patients. Finally, we assessed an alternative method to the classical measurement of MOG-Ab levels by serial dilutions. METHODS: This is a retrospective study including 79 MOG-Ab-positive adult patients, whose samples were obtained at first episode. MOG-Ab were tested by cell-based assay. HEK293 cells were transfected (tHEK293) with human-MOG plasmid. Non-tHEK293 cells were used as negative controls. Assessment of antibody titres was performed by serial dilution, and delta mean fluorescence intensity ratio signal (MOG-ratio MFI) by flow cytometry. MOG-ratio MFI was calculated as follows: (MFI tHEK293cells- MFI non-tHEK293cells)/MFI non-tHEK293cells. MOG-ratio MFI was calculated from the first serum dilution at 1:320. The association between MOG-Ab titres and risk of relapse was analyzed by Cox regression. The association between MOG-Ab titres and visual or motor disability at last follow-up was performed by binary logistic regression. Poor visual outcome was defined when patients displayed some degree of visual disability (visual acuity [VA] < 20/20) and poor motor outcome when patients displayed some degree of motor disability (Disability Status Scale [DSS] > 1). We also investigated correlations between MOG-Ab titres and MOG-ratio MFI. RESULTS: MOG-Ab titres were higher in Caucasians than in those with other ethnicities, and in patients with a more severe VA (VA = 20/100) or motor disability (DSS = 3.0) at onset (p = 0.006, 0.034, and 0.058, respectively). MOG-Ab titres were not associated with risk of relapses or with the final clinical outcome. MOG-ratio MFI correlated with MOG-Ab titres in the whole cohort (? = 0.90; p < 0.001), and when stratified by initial clinical phenotype. CONCLUSION: High MOG-Ab titres at onset are associated with a more severe presentation, but do not predict the future disease course. MOG-ratio MFI is an alternative and straightforward method to determine MOG-Ab levels.

Abstract: International audience; Sodium oxybate (SMO) has been approved in Italy and Austria for the maintenance of abstinence in alcohol dependent (AD) patients. Although SMO is well tolerated in AD patients, cases of abuse and misuse have been reported outside the therapeutic setting. Here we report on a phase IIb double-blind, randomized, placebo-controlled trial for the maintenance of abstinence in AD patients with a new abuse and misuse deterrent formulation of SMO. A total of 509 AD patients were randomized to 12 weeks of placebo or one of four SMO doses (0.75, 1.25, 1.75 or 2.25 g t.i.d.) followed by a one-week medication-free period. The primary endpoint was the percentage of days abstinent (PDA) at end of treatment. An unexpectedly high placebo response (mean 73%, median 92%) was observed. This probably compromised the demonstration of efficacy in the PDA, but several secondary endpoints showed statistically significant improvements. A post-hoc subgroup analysis based on baseline severity showed no improvements in the mild group, but statistically significant improvements in the severe group: PDA: mean difference +15%, Cohen's d = 0.42; abstinence: risk difference +18%, risk ratio = 2.22. No safety concerns were reported. Although the primary endpoint was not significant in the overall population, several secondary endpoints were significant in the intent-to-treat population and post-hoc results showed that treatment with SMO was associated with a significant improvement in severe AD patients which is consistent with previous findings. New trials are warranted that take baseline severity into consideration.

Abstract: Amyotrophic lateral sclerosis is a fatal neurodegenerative disease causing upper and lower motor neuron loss and currently no effective disease-modifying treatment is available. A pathological feature of this disease is neuroinflammation, a mechanism which involves both CNS-resident and peripheral immune system cells. Regulatory T-cells are immune-suppressive agents known to be dramatically and progressively decreased in patients with amyotrophic lateral sclerosis. Low-dose interleukin-2 promotes regulatory T-cell expansion and was proposed as an immune-modulatory strategy for this disease. A randomized placebo-controlled pilot phase-II clinical trial called Immuno-Modulation in Amyotrophic Lateral Sclerosis was carried out to test safety and activity of low-dose interleukin-2 in 36 amyotrophic lateral sclerosis patients (NCT02059759). Participants were randomized to 1MIU, 2MIU-low-dose interleukin-2 or placebo and underwent one injection daily for 5 days every 28 days for three cycles. In this report, we describe the results of microarray gene expression profiling of trial participants' leukocyte population. We identified a dose-dependent increase in regulatory T-cell markers at the end of the treatment period. Longitudinal analysis revealed an alteration and inhibition of inflammatory pathways occurring promptly at the end of the first treatment cycle. These responses are less pronounced following the end of the third treatment cycle, although an activation of immune-regulatory pathways, involving regulatory T-cells and T helper 2 cells, was evident only after the last cycle. This indicates a cumulative effect of repeated low-dose interleukin-2 administration on regulatory T-cells. Our analysis suggested the existence of inter-individual variation amongst trial participants and we therefore classified patients into low, moderate and high-regulatory T-cell-responders. NanoString profiling revealed substantial baseline differences between participant immunological transcript expression profiles with the least responsive patients showing a more inflammatory-prone phenotype at the beginning of the trial. Finally, we identified two genes in which pre-treatment expression levels correlated with the magnitude of drug responsiveness. Therefore, we proposed a two-biomarker based regression model able to predict patient regulatory T-cell-response to low-dose interleukin-2. These findings and the application of this methodology could be particularly relevant for future precision medicine approaches to treat amyotrophic lateral sclerosis., Amyotrophic lateral sclerosis patients included in the IMODALS clinical trial (NCT02059759) were transcriptionally profiled to assess longitudinal blood expression changes. Low-dose-interleukin-2 was shown to promote dose and time-dependent Treg-marker upregulation. However, inter-individual variations were reported in the magnitude of Treg expansion and a two-biomarker model to predict target-engagement was proposed., Graphical Abstract Graphical Abstract

Abstract: Background Remote monitoring of mean arterial blood pressure (MAP), heart rate (HR) or oxygen saturation (SpO2) remains a challenge in outpatient surgery. This study evaluates a new digital technology (Smart Angel™) for remotely monitoring hemodynamic data in real time: data transmitted from the patient’s home to a central server, using a dedicated web-based software package. Methods Adults scheduled for elective outpatient surgery were prospectively enrolled. In the first 5 postoperative days, patients completed a self-report questionnaire (pain, comfort, nausea, vomiting) and recorded SpO2, HR and MAP via two wireless Bluetooth monitors connected to a 4G tablet to transmit the data to a website, in real time, using Smart Angel™ software. Before transmission to the website, these data were also self-reported by the patient on a paper form. The primary outcome was the proportion of variables (self-monitored physiological data + questionnaire scores) correctly transmitted to the hospital via the system compared with the paper version. On Day 5, a system usability scale survey (SUS score 1–100) was also attributed. Results From May 2018 to September 2018, data were available for 29 out of 30 patients enrolled (1 patient was not discharged from hospital after surgery). The remote monitoring technology recorded 2038 data items (62%) compared with 2656 (82%) items recorded on the paper form (p = 0.001). The most common errors with the remote technology were software malfunctioning when starting the MAP monitor and malfunctioning between the tablet and the Bluetooth monitor. No serious adverse events were noted. The SUS score for the system was 85 (68–93) for 26 patients. Conclusion This work evaluates the ability of a pilot system for monitoring remote physiological data using digital technology after ambulatory surgery and highlights the digital limitations of this technology. Technological improvements are required to reduce malfunctioning (4G access, transmission between apps). Trial registration ClinicalTrials.gov (NCT03464721) (March 8, 2018).

Abstract: Background Psychiatric comorbidities are frequent among people who inject drugs, they are associated with a poorer prognosis and need to be addressed. Their interaction with daily heroin injection requires clarification. Methods A cross-sectional survey was conducted among PWID recruited in the city of Haiphong, Vietnam, by respondent-driven sampling. The inclusion criteria were age 18 or older and current injection drug use, verified by skin marks and positive urine tests for heroin or methamphetamine. Data on socio-demographic characteristics, drug use, sexual behaviour and access to treatment were collected using face-to-face questionnaires by trained interviewers. PWID were screened by trained psychiatrists for depression, psychotic disorder and suicidality, using the MINI questionnaire. Results 418 participants were included in the analyses. All were injected heroin users, 21 % were diagnosed with a current major depressive disorder, 15 % with a current psychotic disorder and 12 % presented a suicide risk. In the bivariate analyses, regular meth use, cannabis use and ketamine use were positively associated with presenting at least one psychiatric condition while daily heroin injection and being currently treated with methadone were negatively associated. In the multivariate model, poly-substance use was positively associated with depression (methamphetamine and drinking in addition to heroin) and psychotic disorder (methamphetamine and/or hazardous drinking in addition to heroin) while daily heroin injection and current methadone treatment were negatively and independently associated with depression and psychotic syndrome. Conclusions Our survey confirms the burden of methamphetamine use and the protective effect of methadone but also a possible protective effect of daily heroin injection.

Abstract: International audience; Placenta-mediated pregnancy complications generate short- and long-term adverse medical outcomes for both the mother and the fetus. Nucleosomes and free DNA (fDNA) have been described in patients suffering from a wide range of inflammatory conditions.Objective: The objective of our study was to compare nucleosomes and fDNA circulating levels during pregnancy and particularly in women developing a placenta-mediated complication according to the subtype (preeclampsia or intrauterine growth restriction) (NCT01736826).Patients/methods: A total of 115 women were prospectively included in the study across three groups: 30 healthy non-pregnant women, 50 with normal pregnancy, and 35 with a complicated pregnancy. Blood samples were taken up to every 4 weeks for several women with normal pregnancy and nucleosomes and fDNA were quantified using enzyme-linked immunosorbent assay and quantitative polymerase chain reaction, respectively.Results: We show that nucleosomes and fDNA concentrations significantly increase during normal pregnancy, with concentrations at delivery differing between the two groups. Interestingly, we show that concentrations differ according to the type of placenta-mediated complications, with higher levels in preeclampsia compared to intrauterine growth restriction.Conclusions: These data suggest that nucleosomes and fDNA may be additional actors participating in placenta-mediated pregnancy complications.

Abstract: International audience; Introduction: Ultrasound is a feasible and reproducible method for measuring right diaphragmatic excursion (RDE) in ED patients with acute dyspnea (AD). In AD patients, the correlation between the RDE value and the need for mechanical ventilation (MV) is not known.Materials: This was a bicentric, observational prospective study. The RDE measurement was done at admission. The need for MV was defined by the use of MV within 4 h of AD management. An optimal threshold for RDE was determined as the value that minimized the incorrect predictions of the use of MV in the first 4 h as the highest Youden index.Results: We analyzed 102 patients (79 [70; 86] years), 38 (37%) of whom had been ventilated. The RDE value was 1.7 cm [1.4; 2.0] and 2.2 cm [1.8; 2.6] in the ventilated and non-ventilated groups, respectively (p = 0.06). The AUC was 0.68 95% CI [0.57; 0.80]. With a threshold of 2 cm, the sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV) were 76% [60%; 89%], 59% [46%; 71%], 81% [67%; 91%], and 53% [39%; 66%], respectively. In the non-COPD patients, the RDE values were 1.5 cm [1.2; 1.9] and 2.2 cm [1.8; 2.6] (p < 0.01) in the ventilated and not-ventilated groups, respectively. The AUC was 0.77 95% CI [0.64; 0.90]. With a threshold of 2.18 cm, the sensitivity, specificity, NPV, and PPV were 91% [71%; 99%], 51% [36%; 66%], 92% [75%; 99%], and 54% [38%; 69%], respectively.Conclusion: The RDE values at ED admission were unable to define a prognostic threshold value associated with subsequent MV need in the AD patients. In non-COPD patients, the NPV was 92%.

Abstract: International audience; There are large country variations in COVID-19 death rates that may be partly explained by diet. Many countries with low COVID-19 death rates have a common feature of eating large quantities of fermented vegetables such as cabbage and, in some continents, various spices. Fermented vegetables and spices are agonists of the antioxidant transcription factor nuclear factor (erythroid-derived 2)-like 2 (Nrf2), and spices are transient receptor potential ankyrin 1 and vanillin 1 (TRPA1/V1) agonists. These mechanisms may explain many COVID-19 symptoms and severity. It appears that there is a synergy between Nrf2 and TRPA1/V1 foods that may explain the role of diet in COVID-19. One of the mechanisms of COVID-19 appears to be an oxygen species (ROS)-mediated process in synergy with TRP channels, modulated by Nrf2 pathways. Spicy foods are likely to desensitize TRP channels and act in synergy with exogenous antioxidants that activate the Nrf2 pathway.

Abstract: International audience; Fungi belonging to the Cryptococcus genus and related genera (Filobasidium, Holtermanniella, Naganishia, Papiliotrema, Solicoccozyma, Vishniacozyma) are encapsulated yeasts found in either the environment or animal sources. However, the precise biotopes of most species remain poorly defined. To assess whether wild birds from southern France can carry or spread the most pathogenic species (i.e., species belonging to the C. neoformans and C. gattii complexes), as well as lesser-studied species (non-neoformans/gattii Cryptococcus and former Cryptococcus spp.), 669 birds belonging to 89 species received for care over a two-year period at the Centre de Protection de la Faune Sauvage of Villeveyrac (Bird Protection League nongovernmental organization (NGO) care center) were sampled. Samples were cultured, and Cryptococcus and former Cryptococcus yeasts were identified by PCR sequencing. The purpose was to evaluate whether there was any health risk to local populations or care personnel in aviaries and gather new data on the ecological niches of lesser-known species. One hundred and seven birds (16%) were found to be positive for at least one Cryptococcus or former Cryptococcus species. No yeasts belonging to the highly pathogenic C. neoformans or C. gattii complexes were isolated. However, diversity was notable, with 20 different Cryptococcus or former Cryptococcus species identified. Furthermore, most bird–yeast species associations found in this study have never been described before.

Abstract: IF 10.292; International audience; The hereditary spastic paraplegias are an expanding and heterogeneous group of disorders characterized by spasticity in the lower limbs. Plasma biomarkers are needed to guide the genetic testing of spastic paraplegia. Spastic paraplegia type 5 (SPG5) is an autosomal recessive spastic paraplegia due to mutations in CYP7B1, which encodes a cytochrome P450 7α-hydroxylase implicated in cholesterol and bile acids metabolism. We developed a method based on ultra-performance liquid chromatography electrospray tandem mass spectrometry to validate two plasma 25-hydroxycholesterol (25-OHC) and 27-hydroxycholesterol (27-OHC) as diagnostic biomarkers in a cohort of 21 patients with SPG5. For 14 patients, SPG5 was initially suspected on the basis of genetic analysis, and then confirmed by increased plasma 25-OHC, 27-OHC and their ratio to total cholesterol. For seven patients, the diagnosis was initially based on elevated plasma oxysterol levels and confirmed by the identification of two causal CYP7B1 mutations. The receiver operating characteristic curves analysis showed that 25-OHC, 27-OHC and their ratio to total cholesterol discriminated between SPG5 patients and healthy controls with 100% sensitivity and specificity. Taking advantage of the robustness of these plasma oxysterols, we then conducted a phase II therapeutic trial in 12 patients and tested whether candidate molecules (atorvastatin, chenodeoxycholic acid and resveratrol) can lower plasma oxysterols and improve bile acids profile. The trial consisted of a three-period, three-treatment crossover study and the six different sequences of three treatments were randomized. Using a linear mixed effect regression model with a random intercept, we observed that atorvastatin decreased moderately plasma 27-OHC (∼30%, P < 0.001) but did not change 27-OHC to total cholesterol ratio or 25-OHC levels. We also found an abnormal bile acids profile in SPG5 patients, with significantly decreased total serum bile acids associated with a relative decrease of ursodeoxycholic and lithocholic acids compared to deoxycholic acid. Treatment with chenodeoxycholic acid restored bile acids profile in SPG5 patients. Therefore, the combination of atorvastatin and chenodeoxycholic acid may be worth considering for the treatment of SPG5 patients but the neurological benefit of these metabolic interventions remains to be evaluated in phase III therapeutic trials using clinical, imaging and/or electrophysiological outcome measures with sufficient effect sizes. Overall, our study indicates that plasma 25-OHC and 27-OHC are robust diagnostic biomarkers of SPG5 and shall be used as first-line investigations in any patient with unexplained spastic paraplegia.

Abstract: International audience; Diagnosis of myopathies is challenged by the high genetic heterogeneity and clinical overlap of the various etiologies. We previously reported a Next-Generation Sequencing strategy to identify genetic etiology in patients with undiagnosed Limb-Girdle Muscular Dystrophies, Congenital Myopathies, Congenital Muscular Dystrophies, Distal Myopathies, Myofibrillar Myopathies, and hyperCKemia or effort intolerance, using a large gene panel including genes classically associated with other entry diagnostic categories. In this study, we report the comprehensive clinical-biological strategy used to interpret NGS data in a cohort of 156 pediatric and adult patients, that included Copy Number Variants search, variants filtering and interpretation according to ACMG guidelines, segregation studies, deep phenotyping of patients and relatives, transcripts and protein studies, and multidisciplinary meetings. Genetic etiology was identified in 74 patients, a diagnostic yield (47.4%) similar to previous studies. We identified 18 patients (10%) with causative variants in different genes (ACTA1, RYR1, NEB, TTN, TRIP4, CACNA1S, FLNC, TNNT1, and PAPBN1) that resulted in milder and/or atypical phenotypes, with high intrafamilial variability in some cases. Mild phenotypes could mostly be explained by a less deleterious effect of variants on the protein. Detection of inter-individual variability and atypical phenotype-genotype associations is essential for precision medicine, patient care, and to progress in the understanding of the molecular mechanisms of myopathies.

Abstract: The use of Apps running on smartphones and tablets profoundly affects medicine. The MASK-rhinitis (MACVIA-ARIA Sentinel NetworK for allergic rhinitis) App (Allergy Diary) assesses allergic rhinitis symptoms, disease control and impact on patients' lives. It is freely available in 20 countries (iOS and Android platforms). AIMS: To assess in a pilot study whether (i) Allergy Diary users were able to properly provide baseline characteristics (ii) simple phenotypic characteristics based upon data captured by the Allergy Diary could be identified and (iii) information gathered by this study could suggest novel research questions. METHODS: The Allergy Diary users were classified into six groups according to the baseline data that they entered into the App: (i) asymptomatic; (ii) nasal symptoms excluding rhinorrhea; (iii) rhinorrhea; (iv) rhinorrhea plus 1-2 nasal/ocular symptoms; (v) rhinorrhea plus ≥3 nasal/ocular symptoms; and (vi) rhinorrhea plus all nasal/ocular symptoms. RESULTS: By 1 June 2016, 3260 users had registered with the Allergy Diary and 2710 had completed the baseline questionnaire. Troublesome symptoms were found mainly in the users with the most symptoms. Around 50% of users with troublesome rhinitis and/or ocular symptoms suffered work impairment. Sleep was impaired by troublesome symptoms and nasal obstruction. CONCLUSIONS: This is the first App (iOS and Android) to have tested for allergic rhinitis and conjunctivitis. A simple questionnaire administered by cell phones enables the identification of phenotypic differences between a priori defined rhinitis groups. The results suggest novel concepts and research questions in allergic rhinitis that may not be identified using classical methods info:eu-repo/semantics/publishedVersion

Abstract: Objectives Explore the perceptions and beliefs related to pressure ulcers (PU), their prevention and treatment strategies, in order to discuss potential learning objectives for PU-related therapeutic education in persons with spinal cord injury (SCI). Design Qualitative study, using grounded theory for the analysis of data collected via a questionnaire. Setting Nine SCI referral centers, inpatient care. Participants 131 persons with SCI were included. 76% were male, and 65% presented with paraplegia. The median age was 48 years (33.5; 58) and median time since injury was 11 years (3; 24.5). 70% had experience with PU. Interventions None. Main outcome measures Data collection via an open-ended questionnaire on the representation of PU, its prevention and life experience of having a PU. Results Six categories were identified: (1) identifying what might become problematic, (2) daily preventive actions, (3) detecting the early signs, (4) managing the early signs, (5) need for care, (6) experience with PU and being bedridden. Pressure ulcers have dramatic consequences on psychosocial health. Prevention and treatment require self-management skills, such as self-risk assessment abilities, self-detection skills and problem-solving strategies, to optimise daily PU prevention in persons with SCI. Conclusion PU prevention tackled by persons with SCI bears some specificities that the physician must take into account in the construction of a self-management program in this high-risk population.

Abstract: Bronchodilator response (BDR) testing is used as a diagnostic method in obstructive airway diseases. The aim of this investigation was to compare different methods for measuring BDR in participants with asthma and chronic obstructive pulmonary disease (COPD) and to study to the extent to which BDR was related to symptom burden and phenotypic characteristics.Forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC) were measured before and 15 min after 200 μg of salbutamol in 35 628 subjects aged ≥16 years from three large international population studies. The subjects were categorised in three groups: current asthma (n=2833), COPD (n=1146) and no airway disease (n=31 649). Three definitions for flow-related reversibility (increase in FEV1) and three for volume-related reversibility (increase in FVC) were used.The prevalence of bronchodilator reversibility expressed as increase FEV1 ≥12% and 200 mL was 17.3% and 18.4% in participants with asthma and COPD, respectively, while the corresponding prevalence was 5.1% in those with no airway disease. In asthma, bronchodilator reversibility was associated with wheeze (OR 1.36, 95% CI 1.04–1.79), atopy (OR 1.36, 95% CI 1.04–1.79) and higher exhaled nitric oxide fraction, while in COPD neither flow- nor volume-related bronchodilator reversibility was associated with symptom burden, exacerbations or health status after adjusting for pre-bronchodilator FEV1.Bronchodilator reversibility was at least as common in participants with COPD as those with asthma. This indicates that measures of reversibility are of limited value for distinguishing asthma from COPD in population studies. However, in asthma, bronchodilator reversibility may be a phenotypic marker.

Abstract: International audience; Background and purpose: The prognostic value of serum neurofilament light chain (sNfL), a biomarker of neurodegeneration, compared to other prognos-tic factors of amyotrophic lateral sclerosis (ALS) at the time of diagnosis, remains unclear. Methods: Sera from ALS patients were prospectively collected at the first diagnostic visit in our centre. sNfL levels were determined by single molecule array in 207 ALS patients and in 21 healthy controls. The prognostic value of sNfL was compared with that of other known clinical prognostic factors using a Cox regression model and multivariate analysis. Results: Serum neurofilament light chain levels were higher in ALS patients than in controls (P < 0.0001). Seven parameters were predictive of death in ALS: older age, bulbar onset, higher ALS Functional Rating Scale revised (ALSFRS-R) score, greater weight loss, lower maximal inspiratory pressure, forced vital capacity and higher sNfL levels. A Cox regression model showed that sNfL (P < 0.0001), weight loss (P = 0.040) and site at onset (P = 0.048) were independent predictive factors of death. In a sub-cohort restricted to 139 patients with complete spirometry data, sNfL level (P < 0.005) and forced vital capacity (P = 0.022) were independent factors predictive of death. In a subgroup of 142 patients in whom ALSFRS-R score was available at several time points, sNfL levels positively correlated with ALSFRS-R rate of decline (r = 0.571, P < 10 À12). Conclusions: Higher sNfL concentration is a strong and independent prognos-tic factor of death in ALS as early as the time of diagnosis.

Abstract: International audience; Simultaneous multiple intracerebral hemorrhage (SMICH) is defined as ICH in two or more discrete noncontiguous acute intraparenchymal locations on initial CT. About 5% of ICH patients present with SMICH. ICH/SMICH etiology is classically divided into disorders of primary or secondary origin. About half of primary SMICH cases are caused by cerebral amyloid angiopathy or hypertensive arteriopathy. In this review, we will discuss the radiological features associated with the different causes of primary and secondary ICH and SMICH. Due to its rarity and the associated high morbidity and mortality, we will focus in particular on SMICH.

Abstract: International audience; Background: Links between multimorbidity of allergic diseases and allergen sensitization are still under debate, especially in adults. This study aimed to establish a relationship between polysensitization and allergic multimorbidity in children and adults and the allergens involved in multimorbidity.Material and method: A cross-sectional multicentre study enrolled children aged 6-7 and 13-14 years and adults aged 20-44 years from a Polish national cohort. The diagnosis of allergic diseases was made by a physician. Skin prick tests to 13 allergens and serum IgE levels to 4 allergens were tested.Results: Among the 3856 participants, single disease (asthma, allergic rhinitis or atopic dermatitis) was diagnosed in 27.7% subjects and allergic multimorbidity in 9.3%. Allergic multimorbidity occurred more commonly in children than in adults (p < 0.01). Asthma or atopic dermatitis alone were not associated with polysensitization. Rhinitis and multimorbidity were associated with polysensitization. Allergic multimorbidity occurred in 2.2% of participants with negative skin prick tests, 9.8% of those with one positive prick test (SPT ≥ 3 mm) and 20.6% of polysensitized ones (p < 0.001). There was an increasing risk of multimorbidity depending on the number of positive prick tests for both SPT ≥ 3 mm (OR 9.6-16.5) and SPT ≥ 6 mm (OR 5.9-13.7). A statistically significant relationship was found between allergic multimorbidity and sensitization to cat and mite allergens.Conclusions: Multimorbidity is associated with polysensitization especially in children compared with adults in Polish population cohort. New insights into single disease patterns were found: bronchial asthma is the strongest risk factor for the development of multimorbidity in comparison with allergic rhinitis and atopic dermatitis.

Abstract: Background:Catastrophizing is a negative cognitivo-affective response to an anxiety-provoking stimulus, especially anticipated or actual pain. It can be quickly assessed using a validated questionnaire: the Pain Catastrophizing Scale (PCS)1. Catastrophizing plays a role in maintaining chronic pain and is associated with several pain-related outcomes in osteoarthritis and low back pain. To our knowledge, there are no data on catastrophizing in patients with psoriatic arthritis (PsA).Objectives:To assess the prevalence of catastrophizing and associated factors in PsA.Methods:We performed a bi-centric observational, prospective study. All patients aged 18 or over with PsA fulfilling the 2006 CASPAR criteria were consecutively included. Sociodemographic data, information on the disease and its treatments were collected as well as questionnaires for disease activity (BASDAI), function (HAQ, BASFI), quality of life (SF12, EQ5D), anxiety and depression (HADS, GAD7), fibromyalgia (FiRST), insomnia (ISI) and catastrophizing scores (PCS). Statistical analysis included samples T-test, one-way variance analysis, Spearman’s correlation coefficient, Chi2 test, Fisher’s exact test, Wilcoxon test, multivariate linear regression (considering catastrophizing as a continuous variable) and multivariate logistics regression (considering catastrophizing as a categorical variable: PCS ≥ 20 = high level catastrophizing).Results:From September 2019 to March 2020, 85 PsA patients were included: 54.1% were women, the median age was 54.0 years and 33 patients (39.8%) were professionally active. The majority of patients (88.2%) had a disease lasting for more than 2 years. Axial involvement was found for 39 patients (45.9%), almost all patients (98.8%) had peripheral involvement, 32 patients (37.7%) had enthesitic involvement and 14 patients (16.7%) had erosions. Median DAS28 CRP was 3.12 [2.13-4.46] and the median BASDAI score was 5.50 [4.30-6.70]. The prevalence of a PCS score ≥20 was 45.9% [35.3;56.5]. The median PCS score was 16 [6-29]. In multivariate logistics regression, high-level catastrophizing was significantly associated with the HADS anxiety score (OR=1.35 [1.15-1.61]) and pain VAS (OR=1.04 [1.02-1.06]). In multivariate linear regression, catastrophizing was significantly associated with the HADS anxiety score (p= 0.004), pain VAS (p=0.001), HADS depression score (p=0.018) and insomnia score (p=0.034).Conclusion:Almost half the patients with PsA were high catastrophizers. Catastrophizing is related to anxiety, pain, depression and insomnia. It may be interesting to detect catastrophizing in order to improve the care of our patients.References:[1]Sullivan MJL. et al.

Abstract: Background:Catastrophizing is conceptualized as a negative cognitive–affective response to an anxiety-provoking stimulus, especially anticipated or actual pain. Catastrophizing can be assessed quickly using a validated questionnaire: the Pain Catastrophizing Scale (PCS)1. Catastrophizing plays a role in maintaining chronic pain and is associated with several pain-related outcomes in osteoarthritis and low back pain.Objectives:To assess the prevalence of catastrophizing and associated factors in rheumatoid arthritis (RA).Methods:We performed an observational, prospective, bi-centric study. All patients aged 18 or over with RA and fulfilling the ACR-EULAR 2010 criteria were consecutively included. Sociodemographic data, information on the disease and its treatments were collected as well as questionnaires for disease activity (DAS28), function (HAQ), quality of life (SF12, EQ5D), anxiety and depression (HADS, GAD7), fibromyalgia (FiRST), insomnia (ISI) and catastrophizing scores (PCS). Statistical analysis included the samples t-test, one-way variance analysis, the Spearman’s correlation test, the Chi2 test, Fisher’s exact test, the Wilcoxon test, multivariate linear regression (considering catastrophizing as a continuous variable) and multivariate logistics regression (considering catastrophizing as a categorical variable: PCS ≥ 20 = high level catastrophizing).Results:From September 2019 to March 2020, 201 patients with RA were included: 78.1% were women and the median age was 63.0 years. In all, 64.1% of patients were RF+, 65.7% ACPA+, and 46% had erosive disease. Median DAS28 CRP was 2.9 [2.1-4.0]. with 45% of patients in remission, 14.8% with low, 31.2% moderate and 9 % high activity. The majority of patients (92 %) had a disease lasting for more than 2 years.The prevalence of a PCS score ≥20 was 48.0% [41.0;54.9]. The median PCS score was 18 [7-28]. In multivariate logistics regression, high-level catastrophizing was significantly associated with DAS28-CRP (OR= 1.61 [1.18-2.20]), HADS anxiety score (OR=1.25 [1.11-1.40]) and the HADS depression score (OR=1.19 [1.07-1.33]). In multivariate linear regression, catastrophizing was significantly associated with the HADS anxiety score (p< 0.0001), HADS depression score (p=0.0055), HAQ (p=0.0015) and the ISI insomnia score (p=0.005).Conclusion:Almost half the patients with RA were high catastrophizers. Catastrophizing is linked to anxiety, depression, disease activity, function impairment and insomnia. It may be interesting to detect catastrophizing in order to improve the management of our patients.References:[1]Sullivan MJL. et al.

Abstract: International audience; BACKGROUND: Use of a combination of targeted therapies (COMBIO) in patients with refractory/overlapping immune-mediated inflammatory diseases (IMIDs) has increased, but reported data remain scarce. We aimed to assess effectiveness and safety of COMBIO in patients with IMIDs. METHODS: We conducted a French ambispective multicenter cohort study from September 2020 to May 2021, including adults' patients with 1 or 2 IMIDs and treated at least 3-month with COMBIO. RESULTS: Overall, 143 patients were included. The most common IMIDs were Crohn's disease (63.6%), axial spondyloarthritis (37.7%), and ulcerative colitis (14%). Half of patients had only one IMID, of which 60% were Crohn's disease. Mean duration of COMBIO was 274.5±59.3 weeks, and COMBIO persistence at 104 weeks was estimated at 64.1%. The most frequent COMBIOs combined anti-TNF agents with vedolizumab (30%) or ustekinumab (28.7%). Overall, 50% of patients achieved significant and 27% mild-to-moderate improvement in patient-reported outcomes. Extended duration of COMBIO (aOR=1.09; 95% CI: 1.03-1.14; p=0.002) and diagnoses of two IMIDs (aOR=3.46; 95%CI: 1.29-9.26; p=0.013) were associated with significant improvement in patient-reported outcomes. Incidence of serious infection during COMBIO was 4.51 per 100 person-years (95% CI 2.20-8.27) and 5 COMBIOs were discontinued due to adverse events. CONCLUSIONS: COMBIO can be effective and safe in patients with refractory/overlapping IMIDs.

Abstract: OBJECTIVE In this study, we looked for a new family of latency reversing agents. DESIGN We searched for G-protein-coupled receptors (GPCR) coexpressed with the C-C chemokine receptor type 5 (CCR5) in primary CD4 T cells that activate infected cells and boost HIV production. METHODS GPCR coexpression was unveiled by reverse transcriptase-PCR. We used fluorescence resonance energy transfer to analyze the dimerization with CCR5 of the expressed GPCR. Viral entry was measured by flow cytometry, reverse transcription by quantitative PCR, nuclear factor-kappa B translocation by immunofluorescence, long terminal repeat activation using a gene reporter assay and viral production by p24 quantification. RESULTS Gαi-coupled sphingosine-1-phophate receptor 1 (S1P1) is highly coexpressed with CCR5 on primary CD4 T cells and dimerizes with it. The presence of S1P1 had major effects neither on viral entry nor on reverse transcription. Yet, S1P1 signaling induced NFκB activation, boosting the expression of the HIV LTR. Consequently, in culture medium containing sphingosine-1-phophate, the presence of S1P1 enhanced the replication of a CCR5-, but also of a CXCR4-using HIV-1 strain. The S1P1 ligand FTY720, a drug used in multiple sclerosis treatment, inhibited HIV-1 productive infection of monocyte-derived dendritic cells and of severe combined immunodeficiency mice engrafted with human peripheral blood mononuclear cells. Conversely, S1P1 agonists were able to force latently infected peripheral blood mononuclear cells and lymph node cells to produce virions in vitro. CONCLUSION Altogether these data indicate that the presence of S1P1 facilitates HIV-1 replicative cycle by boosting viral genome transcription, S1P1 antagonists have anti-HIV effects and S1P1 agonists are HIV latency reversing agents.

Abstract: The quest for biomarkers in suicidal behaviors has been elusive so far, despite their potential utility in clinical practice. One of the most robust biological findings in suicidal behaviors is the alteration of the serotonin transporter function in suicidal individuals. Our main objective was to investigate the predictive value of the serotonin transporter gene expression (SLC6A4) for suicidal ideation and as secondary, for suicide attempts in individuals with a major depressive episode (MDE). A 30-week prospective study was conducted on 148 patients with a MDE and 100 healthy controls including 4 evaluation times (0, 2, 8 and 30 weeks). Blood samples and clinical data were collected and SLC6A4 mRNA levels were measured from peripheral blood mononuclear cells using RT-qPCR. We first demonstrated the stability and reproducibility of SLC6A4 mRNA expression measures over time in healthy controls (F=0.658; p=0.579; η2=0.008; ICC=0.91, 95% CI [0.87-0.94]). Baseline SLC6A4 expression level (OR=0.563 [0.340-0.932], p=0.026) as well as early changes in SLC6A4 expression between baseline and the 2nd week (β=0.200, p=0.042) predicted the worsening of suicidal ideation (WSI) in the following 8 weeks. Moreover, changes in SLC6A4 expression between the 2nd and 8th weeks predicted the occurrence of a suicide attempt within 30 weeks (OR=10.976 [1.438-83.768], p=0.021). Altogether, the baseline level and the changes in SLC6A4 mRNA expression during a MDE might predict the WSI and the occurrence of suicidal attempts and could be a useful biomarker in clinical practice.

Abstract: Cutibacterium acnes (formerly Propionibacterium acnes) is recognized as a pathogen in foreign-body infections (arthroplasty or spinal instrumentation). To date, the direct impact of C. acnes on bone cells has never been explored. The clade of 11 C. acnes clinical isolates was determined by MLST. Human osteoblasts and osteoclasts were infected by live C. acnes. The whole genome sequence of six isolates of this collection was analyzed. CC36 C. acnes strains were significantly less internalized by osteoblasts and osteoclasts than CC18 and CC28 C. acnes strains (p ≤ 0.05). The CC18 C. acnes ATCC6919 isolate could survive intracellularly for at least 96 hours. C. acnes significantly decreased the resorption ability of osteoclasts with a major impact by the CC36 strain (p ≤ 0.05). Genome analysis revealed 27 genes possibly linked to these phenotypic behaviors. We showed a direct impact of C. acnes on bone cells, providing new explanations about the development of C. acnes foreign-body infections.

Abstract: Glioblastoma multiforme (GBM) is the most common and aggressive primary brain tumor. This aggressiveness is in part attributed to the closely interrelated phenomena tumor hypoxia and angiogenesis, although few in vivo data exist in human brain tumors. This work aimed to study hypoxia and angiogenesis, in vivo and in situ, in patients admitted with GBM using multimodal imaging. Methods: Twenty-three GBM patients were assessed by 18F-fluoromisonidazole (18F-FMISO) PET and conventional and perfusion MRI before surgery. The level and location of hypoxia (18F-FMISO uptake, evaluated by tumor-to-blood [T/B] ratio), vascularization (cerebral blood volume [CBV]), and vascular permeability (contrast enhancement after gadolinium injection) were analyzed. The spatial relationship between tumor hypoxia and angiogenesis was assessed by an overlap analysis of the volume of 18F-FMISO uptake and the volumes of the high CBV regions and the contrast-enhancement regions. Results: A significant correlation was found between hypoxia and hypervascularization, especially for their maximum values (volume of maximal tumor hypoxia vs. relative CBV: r = 0.61, P = 0.002) and their volumes (hypoxia vs. hypervascularization: r = 0.91, P < 0.001). A large proportion of the high CBVs collocated with hypoxia (81.3%) and with contrast enhancement (46.5%). Conclusion: These results support the hypothesis of a tight association between hypoxia and angiogenesis. Our results suggest that there is insufficient tumor oxygenation in human GBM, despite increased tumor vascularization.

Abstract: Background and ObjectivesThe question of the long-term safety of pregnancy is a major concern in patients with multiple sclerosis (MS), but its study is biased by reverse causation (women with higher disability are less likely to experience pregnancy). Using a causal inference approach, we aimed to estimate the unbiased long-term effects of pregnancy on disability and relapse risk in patients with MS and secondarily the short-term effects (during the perpartum and postpartum years) and delayed effects (occurring beyond 1 year after delivery).MethodsWe conducted an observational cohort study with data from patients with MS followed in the Observatoire Français de la Sclérose en Plaques registry between 1990 and 2020. We included female patients with MS aged 18–45 years at MS onset, clinically followed up for more than 2 years, and with ≥3 Expanded Disease Status Scale (EDSS) measurements. Outcomes were the mean EDSS score at the end of follow-up and the annual probability of relapse during follow-up. Counterfactual outcomes were predicted using the longitudinal targeted maximum likelihood estimator in the entire study population. The patients exposed to at least 1 pregnancy during their follow-up were compared with the counterfactual situation in which, contrary to what was observed, they would not have been exposed to any pregnancy. Short-term and delayed effects were analyzed from the first pregnancy of early-exposed patients (who experienced it during their first 3 years of follow-up).ResultsWe included 9,100 patients, with a median follow-up duration of 7.8 years, of whom 2,125 (23.4%) patients were exposed to at least 1 pregnancy. Pregnancy had no significant long-term causal effect on the mean EDSS score at 9 years (causal mean difference [95% CI] = 0.00 [−0.16 to 0.15]) or on the annual probability of relapse (causal risk ratio [95% CI] = 0.95 [0.93–1.38]). For the 1,253 early-exposed patients, pregnancy significantly decreased the probability of relapse during the perpartum year and significantly increased it during the postpartum year, but no significant delayed effect was found on the EDSS and relapse rate.DiscussionUsing a causal inference approach, we found no evidence of significantly deleterious or beneficial long-term effects of pregnancy on disability. The beneficial effects found in other studies were probably related to a reverse causation bias.

Abstract: Background Prognosis of unresectable glioblastoma (GB) remains poor, despite temozolomide (TMZ)-based chemoradiation. Activity of bevacizumab (BEV) and irinotecan (IRI) has been reported in recurrent disease. We evaluated BEV and IRI as neo-adjuvant and adjuvant treatment combined with TMZ-based chemoradiation for unresectable GB. Patients and methods Patients with unresectable GB, age 18–70, IK ≥50 were eligible. The experimental arm (BEV/IRI) consisted of neo-adjuvant intravenous BEV, 10 mg/kg, and IRI, 125 mg/m2, every 2 weeks for four cycles before radiotherapy (RT) (60 Gy), concomitant oral TMZ, 75 mg/m2/day, and BEV, 10 mg/kg every 2 weeks. Adjuvant BEV and IRI were given every 2 weeks for 6 months. The control arm consisted of concomitant oral TMZ, 75 mg/m2/day during RT, and 150–200 mg/m2 for 5 days every 28 days for 6 months. The use of BEV was allowed at progression in the control arm. Results Patients (120) were included from April 2009 to January 2011. The working hypothesis was that treatment would increase the progression-free survival at 6 month (PFS-6) from 50% to 66%. The primary objective was not achieved, and only 30 out of 60 patients were alive without progression at 6 months (50.0% [IC95% (36.8; 63.1)] in the BEV/IRI arm when 37 out of 60 patients were required according to the Fleming decision rules. PFS-6 was 7.1 months in BEV/IRI versus 5.2 months in the control arm. The median overall survival was not different between the two arms (11.1 months). Main toxicities were three fatal intracranial bleedings, three bile duct or digestive perforations/infections (1 fatal), and six thrombotic episodes in the BEV/IRI arm, whereas there was one intracranial bleeding, two bile duct or digestive perforations/infections (1 fatal), and one thrombotic episode in the control arm. Conclusions Neo-adjuvant and adjuvant BEV/IRI, combined with TMZ-radiation, is not recommended for further evaluation in the first-line treatment of unresectable GB. Clinical trial registration Clinical trial registered under EUDRACT number 2008-002775-28 (NCT01022918).

Abstract: International audience; Information and communication technologies (ICT) are promising for the long-term care of older and frequently frail people. These innovations can improve health outcomes, quality of life and efficiency of care processes, while supporting independent living. However, they may be disruptive innovations. As all European member states are facing an increasing complexity of health and social care, good practices in ICT should be identified and evaluated. Three projects funded by DG CNECT are related to Active and Healthy Ageing (AHA) and frailty: (i) BeyondSilos, dealing with independent living and integrated services, (ii) CareWell, providing integrated care coordination, patient empowerment and home support and (iii) SmartCare, proposing a common set of standard functional specifications for an ICT platform enabling the delivery of integrated care to older patients. The three projects described in this paper provide a unique pan-European research field to further study implementation efforts and outcomes of new technologies. Below, based on a description of the projects, the authors display four domains that are in their views fundamental for in-depth exploration of heterogeneity in the European context: 1. Definition of easily transferable, high level pathways with solid evidence-base; 2. Change management in implementing ICT enabled integrated care; 3. Evaluation and data collection methodologies based on existing experience with MAST and MEDAL methodologies; and 4. Construction of new models for delivery of health and social care. Understanding complementarity, synergies and differences between the three unique projects can help to identify a more effective roll out of best practices within a varying European context.

Abstract: BackgroundUltrasound (US) guidance has yet to prove its applicability in radial arterial blood gas analysis (ABGA) punctures. The main objective of our study was to compare the number of first-attempt successes (NFAS) for radial arterial puncture in difficult patients with or without US guidance. The Secondary aims were to compare the number of punctures (NOP), puncture time, and patient pain.MethodsIn this single-center, randomized controlled trial, patients who required a radial ABGA and in whom the arterial puncture was assessed as difficult (because of non-palpable radial arteries or two previous puncture failures by a nurse) were assigned to the US group or no-US (NUS) group (procedure performed by a trained physician).ResultsThirty-six patients were included in the US group and 37 in the NUS groups. The NFAS was 7 (19%) in the NUS group and 19 (53%) in the US group. The relative risk of success in the US group was 2.79 (95% CI,1.34 to 5.82), p = 0.01. In the NUS and US groups, respectively, the median NOP was 3 [2; 6] vs. 1 [1; 2], estimated difference -2.0 (95%CI, -3.4 to -0.6), p < 0.01; the respective puncture time was 3.1 [1.6; 5.4] vs. 1.4 [0.6; 3.1] min, estimated difference -1.45 (95%CI, -2.57 to -0.39), p = 0.01; the respective median patient pain was 6 [4; 8] vs. 2 [1; 4], estimated difference -4.0 (95%CI, -5.8 to -2.3); p < 0.01.ConclusionUS guidance by a trained physician significantly improves the rate of success in difficult radial ABGA patients.

Abstract: International audience; Background: SARS-CoV-2 infection can induce cardiac damage. Therefore, in the absence of clear data, a cardiac evaluation was recommended for athletes before returning to play after recent SARS-CoV-2 infection.Aim: To assess the proportion of anomalies detected by this cardiac screening.Methods: We reviewed the medical files of elite athletes referred for cardiac evaluation before returning to play after a non-hospitalized SARS-CoV-2 infection (based on a positive polymerase chain reaction or antigen test) from March 2020 to July 2021 in 12 French centres.Results: A total of 554 elite athletes (professional or national level) were included (median age 22 years, 72.0% male). An electrocardiogram (ECG), echocardiogram and exercise test were performed in 551 (99.5%), 497 (89.7%) and 293 (52.9%) athletes, respectively. We found anomalies with a potential link with SARS-CoV-2 infection in four ECGs (0.7%), three echocardiograms (0.6%) and three exercise tests (1.0%). Cardiac magnetic resonance imaging was performed in 34 athletes (6.1%), mostly due to abnormal first-line examinations, and was abnormal in one (2.9%). The rates of those abnormalities were not higher among athletes with cardiac symptoms or more severe forms of non-hospitalized SARS-CoV-2 infection. Only one athlete had a possible SARS-CoV-2 myocarditis and sport was temporally contraindicated. None had a major cardiac event declared during the follow-up.Conclusion: The proportion of cardiac involvement after non-hospitalized forms of SARS-CoV-2 infection in athletes are very low. Systematic cardiac screening before returning to play seems to be unnecessary.

Abstract: International audience; Before the Omicron era, the neutralizing antibody targeting the SARS-CoV2 Spike protein Sotrovimab has been shown to reduce the risk of COVID-19-related hospitalization in patients who are at high risk for progression (1, 2). We recently showed that early administration of Sotrovimab in Omicron-infected patients with very high-risk for progression was associated with a low rate of COVID-19-related hospitalization within one month after treatment administration (3%), and with no death (1). However, the dominance of the Omicron sublineage BA.2 led health agencies to suspend Sotrovimab emergency use authorizations because of its lower neutralizing ability in vitro compared to BA.1 sublineage (3, 4). Clinical efficiency of Sotrovimab to prevent COVID-19 related complications in high-risk patients with mild-to-moderate COVID-19 Omicron BA.2 remains unknown. Our aim was to compare the clinical and virological outcomes of Omicron BA.1 and BA.2-infected patients with mild-to-moderate COVID-19 who received 500 mg of Sotrovimab IV to prevent COVID-19-related complications.

Abstract: International audience; Background: After the Food and Drug Administration alert about antiepileptic medication and suicide, incident epilepsy has been associated with first or recurrent suicide attempts independently of psychiatric comorbidities and antiepileptic treatment. Following this thread, the aim of this study was to analyze if epilepsy was associated with a higher severity of lifetime suicide attempts (SAs).Methods: Analyses were carried out on 1677 adults hospitalized between 1999 and 2012 after a SA in a specialized ward for affective episodes. Five severity features were studied: frequent SAs (>2), early onset of first SA (≤26 years), history of violent SA, high suicide intent and high lethality of the SA. Adjusted logistic regression models were used to estimate the association between the lifetime diagnosis of epilepsy and the severity features.Results: Among suicide attempters, ninety-three patients reported a lifetime diagnosis of epilepsy (5.5%). Epileptic patients diagnosed after the first SA were more likely to be frequent suicide attempters than non-epileptic ones. They showed also higher SA planification scores.Limitations: Diagnosis accuracy is limited by the use of self-reports for epilepsy. The lack of precise information about the disease course and treatment have not allowed for further statistical analysis. With regard to psychiatric comorbidities, personality disorders could not be taken into account.Conclusions: Suicide attempters with epilepsy present an increased severity in some aspects of their suicidal behavior regardless of demographic and clinical variables. Our results give support to the existence of a bidirectional association between epilepsy and suicidal behavior.

Abstract: International audience; Background: in patients with ST-segment elevation myocardial infarction and multivessel disease, percutaneous coronary intervention for non-culprit lesions is superior to treatment of the culprit lesion alone. The optimal timing for non-infarct-related artery revascularization - immediate versus staged - has not been investigated adequately. Aim: we aimed to assess clinical outcomes at 1 year in patients with ST-segment elevation myocardial infarction with multivessel disease using immediate versus staged non-infarct-related artery revascularization. Methods: outcomes were analysed in patients from the randomized FLOWER-MI trial, in whom, after successful primary percutaneous coronary intervention, non-culprit lesions were assessed using fractional flow reserve or angiography during the index procedure or during a staged procedure during the initial hospital stay, ≤5 days after the index procedure. The primary outcome was a composite of all-cause death, non-fatal myocardial infarction and unplanned hospitalization with urgent revascularization at 1 year. Results: among 1171 patients enrolled in this study, 1119 (96.2%) had complete revascularization performed during a staged procedure, and 44 (3.8%) at the time of primary percutaneous coronary intervention. During follow-up, a primary outcome event occurred in one of the patients (2.3%) with an immediate strategy and in 55 patients (4.9%) with a staged strategy (adjusted hazard ratio 1.44, 95% confidence interval 0.39-12.69; P=0.64). Conclusions: staged non-infarct-related artery complete revascularization was the strategy preferred by investigators in practice in patients with ST-segment elevation myocardial infarction with multivessel disease. This strategy was not superior to immediate revascularization, which, in the context of this trial, was used in a small proportion of patients. Further randomized studies are needed to confirm these observational findings.
