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

Abstract
OBJECTIVES The behavioral summarized evaluation scales, the BSE and its revised version the BSE-R, were developed and validated in the 1980-1990s. The BSE-R is still used daily by clinical teams in France and foreign countries, and it is recommended by the French Health Authority (2018). Having taken into account knowledge improvement in neurodevelopment and autism spectrum disorder (ASD) and the importance of observation by relatives in ecological context, the second version of the BSE was developed. This paper presents the construction and the validation study of the second version of the behavioral summarized evaluation scale, the BSE2 and the BSE2-P rated by parents. METHODS Construct validity of the BSE2 scale has been studied in a population of 244 children and adolescents with ASD according to DSM-5 criteria, aged from 30 months to 18 years. Discriminant validity has been analyzed using a population of 86 patients of the same age, with neurodevelopmental disorder (NDD) without comorbidity of ASD. RESULTS BSE2 comprises 30 items and is a two-dimensional scale as was BSE-R. Both dimensions, labelled "Interaction" (11 items) and "Modulation" (11 items), accounted for 41.7 % of the total variance. They describe autism severity and are in accordance with the two DSM-5 dimensions. Internal consistency (0.927 and 0.850 respectively) and inter-rater reliability (0.932 and 0.897 respectively) are good or excellent for both dimensions. Sensibility and specificity (0.758 and 0.767 respectively) range BSE2 among the tools with good psychometric properties. The parent version, BSE2-P, dedicated to ecological context is easily rated by parents. CONCLUSIONS BSE2 scale for children and adolescents is a clinical tool with good psychometric properties. Its two-dimensional structure is in accordance with DSM-5 criteria. This scale covers all spectrum of ASD clinical forms in both children and adolescents. It can be used to identify ASD in complex neurodevelopmental disorders with several comorbidities and can help to distinguish autism symptomatology from other neurodevelopmental diagnoses. Furthermore, this scale allows to expand the rating context, involving parents to define and adjust the individualized therapeutic project. Thus the BSE2 is a valuable clinical tool for practitioners for both diagnosis and follow-up.

Abstract
Penile Mondor's disease (PMD), or thrombosis of the dorsal vein, is an under-reported benign condition. Its aetiology is poorly understood. Clinically, it presents as a palpable cord in the dorsal vein of the penis, with pain or local discomfort, especially during erection. PMD may be diagnosed based on the medical history and physical examination. Management of the condition is conservative, with practitioners opting for various strategies including sexual/masturbatory abstinence, localised anticoagulant topical therapy and oral nonsteroidal anti-inflammatory drugs. In many cases, PMD will resolve within 4-8 weeks of presentation. Thrombectomy and resection of the superficial penile vein are applied surgically in patients refractory to the medical treatment. We describe the case of a 33-year-old patient known to have HIV who presented for severe painful dorsal induration and swelling of the proximal third of the penis. The patient had no recent history of sexual intercourse, penile trauma or other well-known risk factors for PMD. The physical examination was unequivocal, so a Doppler ultrasound was performed. A diagnosis of PMD was made and conservative treatment was prescribed. During a follow-up visit after 6 weeks, the patient had no symptoms and physical examination did not reveal anything pathological.

Abstract
The trace metal iron (Fe) controls the diversity and activity of phytoplankton across the surface oceans, a paradigm established through decades of in situ and mesocosm experimental studies. Despite widespread Fe-limitation within high-nutrient, low chlorophyll (HNLC) waters, significant contributions of the cyanobacterium Synechococcus to the phytoplankton stock can be found. Correlations among differing strains of Synechococcus across different Fe-regimes have suggested the existence of Fe-adapted ecotypes. However, experimental evidence of high- versus low-Fe adapted strains of Synechococcus is lacking, and so we investigated the transcriptional responses of microbial communities inhabiting the HNLC, sub-Antarctic region of the Southern Ocean during the Spring of 2018. Analysis of metatranscriptomes generated from on-deck incubation experiments reflecting a gradient of Fe-availabilities reveal transcriptomic signatures indicative of co-occurring Synechococcus ecotypes adapted to differing Fe-regimes. Functional analyses comparing low-Fe and high-Fe conditions point to various Fe-acquisition mechanisms that may allow persistence of low-Fe adapted Synechococcus under Fe-limitation. Comparison of in situ surface conditions to the Fe-titrations indicate ecological relevance of these mechanisms as well as persistence of both putative ecotypes within this region. This Fe-titration approach, combined with transcriptomics, highlights the short-term responses of the in situ phytoplankton community to Fe-availability that are often overlooked by examining genomic content or bulk physiological responses alone. These findings expand our knowledge about how phytoplankton in HNLC Southern Ocean waters adapt and respond to changing Fe supply.

Abstract
Understanding the mechanisms leading to the multitude of newly-formed compounds generated during the thermal processing of food is important for the reasoned construction of quality. Thanks to a solid food model with a structure and technological history comparable to that of a real sponge cake and containing only known amounts of precursors (glucose with or without leucine), an adapted reaction scheme unravelling Maillard and caramelization reactions was built and then compared to experimental kinetic data measured on numerous reaction markers (precursors, α-dicarbonyl intermediates and furanic compounds). For caramelization, this study showed that glucose mainly formed 1,2-enediol and then fructose rather than glucosone and glyoxal. 5-hydroxymethylfurfural started to form when there were sufficient quantities of fructose, and 3,4-dideoxyoglucosone was not generated until after this step. Furfural was mainly formed via 3-deoxyglucosone. The involvement of leucine tended to accelerate the breakdown of sugars as more degradation pathways (via enaminols) were added.

Abstract
The application of gold nanoparticle-peptide conjugates as theranostic agents for colorectal cancer shows much promise. This study aimed at determining the neurotoxic impact of 14 nm gold nanoparticles (AuNPs) functionalized with colorectal cancer-targeting peptides (namely p.C, p.L or p.14) in a rat model. Brain tissue samples, obtained from Wistar rats that received a single injection of citrate-capped AuNPs, polyethylene glycol-coated (PEG) AuNPs, p.C-PEG-AuNPs, p.L-PEG-AuNPs or p.14-PEG-AuNPs, and sacrificed after 2- and 12-weeks, respectively, were analysed. Inflammation marker (tumour necrosis factor-α, interleukin-6, interleukin-1β), oxidative stress (superoxide dismutase, catalase, glutathione peroxidase) and apoptotic biomarker (cytochrome c, caspase-3) levels were measured. Gold nanoparticle-treated groups sacrificed after 2-weeks did not exhibit any significant inflammatory, oxidative stress or apoptotic effects in brain tissue compared to the untreated control group. In brain tissue from rats that were exposed to citrate-capped AuNPs for 12-weeks, tumour necrosis factor-α and interleukin-6 levels were significantly increased compared to the untreated control. Exposure to PEG-AuNP, p.C-PEG-AuNP, p.L-PEG-AuNP and p.14-PEG-AuNP did not elicit significant toxic effects compared to the control after 12-weeks, as evidenced by the absence of inflammatory, oxidative stress and apoptotic effects in brain tissue. We thus report on the safety of PEG-coated AuNP-peptide conjugates for potential application in the diagnosis of colorectal cancer; however, exposure to citrate-capped AuNPs could induce delayed neuro-inflammation, and as such, warrants further investigation.

Abstract
OBJECTIF Evaluate kidney autotransplantation (KAT) and ileal ureter substitution (IUS) practice and outcome as alternatives to indwelling ureteral stents for the management of long ureteral stenosis (US). MATERIAL We included all patients treated for US with KAT or IUS in 5 French university urology centers between 2010 and 2018. We excluded US due to urothelial carcinoma. Primary endpoint was the preservation of ipsilateral kidney and renal function without any urinary diversion. RESULTS 22 patients were treated with KAT (n=8, 36.4%) and IUS (n=14, 63.6%). Mean US length was 4.6cm and 6cm (P=0.52) in KAT and IUS groups respectively. US etiologies were lithiasis, iatrogenic, retroperitoneal fibrosis or extrinsic compression. US level was varied. The surgery was described as difficult because of peritoneal adhesions or major peri-ureteral fibrosis. Mean operating time and hospital stay were 336 and 346minutes (P=0.87) and 8 and 15 days respectively (P=0.001). Postoperative complications were mostly Clavien ≤2 (n=17, 77.3%). Revision surgery was required in the KAT group in 3 cases (37.5%), for textiles, renal vein thrombosis and anastomotic leak, none in the IUS group. The mean follow-up was 15.7 months. All but one (in the KAT group) ipsilateral kidneys were preserved, without renal function impairment (Δcreat +2.1 vs. +2.4μmol/l respectively, P=0.67), nor urinary diversion. CONCLUSION KAT and IUS are safe alternatives whose indication depends on surgeons expertise. Our study pointed out the scarcity of this practice suggesting the need to refer patients to expert centers. LEVEL OF EVIDENCE 3.

Abstract
Background There is limited information describing the characteristics and outcomes of hospitalized older patients with confirmed coronavirus disease 2019 (COVID-19). Method We conducted a multicentric retrospective cohort study in 13 acute COVID-19 geriatric wards, from March 13 to April 15, 2020, in Paris area. All consecutive patients aged 70 years and older, with confirmed COVID-19, were enrolled. Results Of the 821 patients included in the study, the mean (SD) age was 86 (7) years; 58% were female; 85% had ≥2 comorbidities; 29% lived in an institution; and the median [interquartile range] Activities of Daily Living scale (ADL) score was 4 [2–6]. The most common symptoms at COVID-19 onset were asthenia (63%), fever (55%), dyspnea (45%), dry cough (45%), and delirium (25%). The in-hospital mortality was 31% (95% confidence interval [CI] 27–33). On multivariate analysis, at COVID-19 onset, the probability of in-hospital mortality was increased with male gender (odds ratio [OR] 1.85; 95% CI 1.30–2.63), ADL score <4 (OR 1.84; 95% CI 1.25–2.70), asthenia (OR 1.59; 95% CI 1.08–2.32), quick Sequential Organ Failure Assessment score ≥2 (OR 2.63; 95% CI 1.64–4.22), and specific COVID-19 anomalies on chest computerized tomography (OR 2.60; 95% CI 1.07–6.46). Conclusions This study provides new information about older patients with COVID-19 who are hospitalized. A quick bedside evaluation at admission of sex, functional status, systolic arterial pressure, consciousness, respiratory rate, and asthenia can identify older patients at risk of unfavorable outcomes.

Abstract
Background Whilst there are a number of publications comparing the relationship between body mass index (BMI) of kidney transplant recipients and graft/patient survival, no study has assessed this for a French patient cohort. Methods In this study, cause-specific Cox models were used to study patient and graft survival and several other time-to-event measures. Logistic regressions were performed to study surgical complications at 30 days post-transplantation as well as delayed graft function. Results Among the 4691 included patients, 747 patients were considered obese with a BMI level greater than 30 kg/m2. We observed a higher mortality for obese recipients (HR = 1.37, p = 0.0086) and higher risks of serious bacterial infections (HR = 1.24, p = 0.0006) and cardiac complications (HR = 1.45, p < 0.0001). We observed a trend towards death censored graft survival (HR = 1.22, p = 0.0666) and no significant increased risk of early surgical complications. Conclusions We showed that obesity increased the risk of death and serious bacterial infections and cardiac complications in obese French kidney transplant recipients. Further epidemiologic studies aiming to compare obese recipients versus obese candidates remaining on dialysis are needed to improve the guidelines for obese patient transplant allocation.

Abstract
Abstract
Background
The arrival of highly effective, well-tolerated, direct-acting antiviral agents (DAA) led to a dramatic decrease in hepatitis C virus (HCV) prevalence. Human immunodeficiency virus (HIV)-HCV–coinfected patients are deemed a priority population for HCV elimination, while a rise in recently acquired HCV infections in men who have sex with men (MSM) has been described. We describe the variations in HIV-HCV epidemiology in the French Dat’AIDS cohort.
Methods
This was a retrospective analysis of a prospective cohort of persons living with HIV (PLWH) from 2012 to 2018. We determined HCV prevalence, HCV incidence, proportion of viremic patients, treatment uptake, and mortality rate in the full cohort and by HIV risk factors.
Results
From 2012 to 2018, 50 861 PLWH with a known HCV status were followed up. During the period, HCV prevalence decreased from 15.4% to 13.5%. HCV prevalence among new HIV cases increased from 1.9% to 3.5% in MSM but remained stable in other groups. Recently acquired HCV incidence increased from 0.36/100 person-years to 1.25/100 person-years in MSM. The proportion of viremic patients decreased from 67.0% to 8.9%. MSM became the first group of viremic patients in 2018 (37.9%). Recently acquired hepatitis represented 59.2% of viremic MSM in 2018. DAA treatment uptake increased from 11.4% to 61.5%. More treatments were initiated in MSM in 2018 (41.2%) than in intravenous drug users (35.6%). In MSM, treatment at the acute phase represented 30.0% of treatments in 2018.
Conclusions
A major shift in HCV epidemiology was observed in PLWH in France from 2012 to 2018, leading to a unique situation in which the major group of HCV transmission in 2018 was MSM.

Abstract
Background:Despite available highly effective pharmacological treatments, up to 30% of current rheumatoid arthritis (RA) patients remain in quasi-remission, where inflammation is controlled but patients still report unacceptable levels of negative impact of RA (high Patient Global Assessment (PGA) on a 0-10 visual analog scale). PGA levels correlated with depressive symptoms assessed by Center for Epidemiologic Studies- Depression (CES-D) scores. Mindfulness-Based Stress Reduction (MBSR) is relatively inexpensive and reduces both anxiety and depression in several conditions.Objectives:To complete a feasibility and acceptability study paving the way for a randomized controlled trial (RCT) of MBSR to improve depressive symptoms and clinical outcomes in RA patients in quasi-remission.Methods:A standardized 8-week MBSR program in adults with controlled inflammatory disease (stable SJC ≤ 2/66 and normal CRP; stable treatments) but high CES-D scores (2 groups), high CES-D or anxiety scores (1 group), or PGA higher than Physician Evaluation of Disease Activity (EVA) by ≥2 (1 group). Feasibility was documented using process indicators. Outcomes were measured at baseline and 6 months after the end of MBSR. Disease activity scores (SDAI) and questionnaires on depressive symptoms (CES-D), HAQ, sleep (VAS), fatigue and pain (SF-36), anxiety (GAD-7), PGA were collected. Qualitative interviews based on a theoretical framework of acceptability were conducted following the post-MBSR evaluation.Results:We report on the first 21 patients (mean age 59, 91% females) having completed their 6-month follow up evaluation. Factors leading to higher recruitment rates were 1) using pragmatic scores to identify eligible patients (e.g. EVA and PGA), 2) no formal clinical evaluation of mental health and no emphasis on depression in the recruitment material.MBSR had a highly significant positive impact on depressive symptoms (p=0.003) and anxiety (p=0.025) (Figure), and positive impact on quality of sleep and HAQ. No change in SDAI or joint counts was noted.During a qualitative interview of 13 participants, most reported that MBSR helped them control their reactions to daily stressful situations. Perceptions were almost uniformly positive towards MBSR, and most appeared to have integrated some part of it in their daily life. No side effects were reported.Conclusion:Although recruitment was challenging, a MBSR trial in RA patients in quasi-remission was found acceptable and feasible. Positive impacts on mood and on clinical outcomes were observed. Anxiety and depression scores appear the most sensitive to change and are recommended as the primary outcome for an eventual RCT. MBSR added to conventional treatments might help empower RA patients towards self-management.Acknowledgments:Grant support from Canadian Initiative for Outcomes in Rheumatology cAre (CIORA)Disclosure of Interests:Marie-Claude Beaulieu: None declared, Isabelle Gaboury: None declared, Nathalie Carrier: None declared, Patricia Dobkin: None declared, France Gervais: None declared, Françoise Gendron: None declared, Pasquale Roberge: None declared, Pierre Dagenais: None declared, Sophie Roux: None declared, Gilles Boire Grant/research support from: Merck Canada (Registry of biologices, Improvement of comorbidity surveillance)Amgen Canada (CATCH, clinical nurse)Abbvie (CATCH, clinical nurse)Pfizer (CATCH, Registry of biologics, Clinical nurse)Hoffman-LaRoche (CATCH)UCB Canada (CATCH, Clinical nurse)BMS (CATCH, Clinical nurse, Observational Study Protocol IM101664.

Abstract
Background:Since July 1998, the Early Undifferentiated PolyArthritis (EUPA) cohort recruited consecutive adults with recent-onset immune-mediated polyarthritis1,2. Patients were treated aiming at 0 swollen joint.Objectives:To analyze the impact of biomarkers over 20 years on baseline variables, treatments, comorbidities and outcomes over the first 5 years of follow up.Methods:Variables and Outcomes were collected over 5 years in consecutive patients fulfilling RA criteria, grouped according to date of inclusion (Period 1: 1998-2004; Period 2: 2005-2010; Period 3: 2011-2018). Comparisons of baseline characteristics, treatment, and outcomes over 5 years between the 3 Periods were previously presented (ACR 2018 and 2019). Erosive damage was scored according to Sharp/van der Heijde; erosive status was defined as ≥5 Erosion units. We now present observed associations between the presence of baseline prognostic biomarkers (anti-CCP2 (ACPA), RF, anti-Sa, and erosive status) with concomitant and subsequent disease activity levels, radiographic scores, comorbidities and impact of treatment. False discovery rate correction was used to adjust p-values for multiple comparisons.Results:753 patients were included: 247, 263 and 243 in Periods 1, 2 and 3, respectively. Variables at baseline. No biomarkers, including erosive status, were associated with demographics or disease activity. Erosive disease was more prevalent in ACPA+ (19.9% vs 13.9%, p=0.0417). Current smoking decreased by period (20.6, 17.2, 8.6%; p=0.02) in ACPA negatives only, remaining stable among ACPA+ (25.3, 20.9, 18.8%, NS). All comorbidities were significantly more present in ACPA negatives vs positives (RR between 1.55 and 1.99). Prevalence of cardiovascular (CV; 44.8, 55.0, 60.0%; p=0.036) and cancer (4.1, 7.1, 13.1%; p=0.02) comorbidities increased over time in ACPA negatives and remained stable in ACPA+ (CV: 33.0, 30.8, 40.7, NS; cancer: 3.0, 4.4, 6.2, NS). RF positivity decreased by period (47.8, 36.9, 36.7%, p=0.03), but ACPA+ remained stable (40.8, 35, 35.4% NS).Outcomes over 5 years of follow up.There was no link between the presence of any biomarker and subsequent disease activity scores. Positive ACPA, RF and anti-Sa at baseline predicted development of more erosive status (RR = 1.50; 1.37 and 1.52, all p<0.001). 68% reached DAS28 remission overall (70.3% in ACPA negatives, 65.2% in ACPA+). Independent of ACPA status, remission rates increased between Periods 1 vs 2 (RR = 1.14, p=0.04) and 1 vs 3 (RR=1.13, p=0.055), but not between 2 vs 3. CV comorbidities among ACPA+ increased significantly more over time vs ACPA negatives (+8.9% vs +4.1%; RR = 1.18, p=0.03). Erosion scores increased significantly more in ACPA+ treated with DMARDs only vs receiving a biologic (ΔSharp: 3.98 vs 3.11, p= 0.026; ΔErosions: 2.58 vs 1.83, p= 0.02). By period, erosive status decreased significantly (Periods 2 vs 1: RR= 0.65, p=0.002; 3 vs 1: RR=0.42, p=0.002; 3 vs 2: RR=0.64, p=0.007), both in ACPA+ and negatives.Conclusion:In this cohort of recent onset RA recruited over 20 years, we observed a constant drift towards RF-negative arthritis at baseline with decreasing smoking rates and increasing comorbidities in seronegative patients. Positive antibodies were associated more cardiovascular comorbidities accrual. Autoantibody positive (especially ACPA+) patients developed more erosive disease and had better erosion outcomes with biologic treatments. Irrespective of the presence or absence of biomarkers, marked improvements in control of disease activity and in remission rates occured over each period.References:[1]Boire G, et al.Arthritis Res Ther2005;7:R592-R603;[2]Carrier N, et al.

Abstract
INTRODUCTION Psychomotor impairments in Autism Spectrum Disorders (ASD) have frequently been described in scientific literature. Such deficits impact upon the development of social motor function and interfere with the ability to adjust to everyday life. The inclusion of sensory-motor signs in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) confirms their importance in the diagnosis of ASD. Previous literature has shown the presence precocity of these signs, sometimes before the alteration of the social communication. To our knowledge, there are no existing clinical tools to measure sensory-psychomotor deficit, specifically in ASD. The current paper presents the construction and validation of a new scale, designed to evaluate sensory-psychomotor signs in Autism: 'the Sensory-psychomotor Particularities Scale in Autism' (SPSA). METHOD The scale is composed of 160 items describing common sensory-psychomotor signs in autism. These items are grouped into 20 variables: touch, nociception, vestibular sensitivity, proprioceptive sensitivity, vision, auditory, multimodality, tone, posture, balance, global coordination, manual dexterity, body schema, bodily self-consciousness, relational adjustment, emotional expression, use of objects, space, time and tonico-emotional regulation. For each item, the psychomotor therapist evaluated sensori-psychomotor signs according to a five-level Likert scale (0="the sign is never expressed by the person", 1="weakly expressed", 2="moderately expressed", 3="severely expressed" and 4="the sign is very characteristic of the person and very severely expressed"). This is completed by a family interview in order to assess the impact of these signs on everyday situations. The study included 111 children with autism. The presence of neurological and genetic diseases was exclusion criteria. For each child, a global developmental evaluation was carried out by an expert clinical team specializing in ASD. Standardized clinical tools were used: Autism Diagnostic Observation Schedule (ADOS), Childhood Autism Rating Scale (CARS), Behavior Summarized Evaluation scale (BSE-R), Repeated and Restricted Behavior scale (RRB), Movement Assessment Battery for Children (M-ABC), Motor Development Rating scale (MDR), Sensory Profile (SP). Developmental quotients (DQ) were evaluated using various tests depending on age and ability. RESULTS Factor analysis produced three clinically relevant factors: F1: "sensory-emotional synchronization", F2: "multisensory integration" and F3: "motor skills": each containing a similar quantity of items. They account for roughly equal percentages of variance (18.9%, 18.0%, 16.8%, respectively). The factorial structure does not change if the 26 children with comorbid developmental coordination disorder are removed. The three factors show good internal consistency and excellent inter-rater reliability. F1 is comprised of 6 items: touch, nociception, proprioceptive sensitivity, vision, emotional expression and tonico-emotional regulation. This factor is significantly associated with items of the Sensory Profile (touch processing, poor registration, sensory seeking). F2 is comprised of 5 items: multimodality, bodily self-consciousness, relational adjustment, use of objects and space. This factor is associated with ADOS, BSE-R and RRB scores, and the item "touch processing" of the Sensory Profile. F3 is comprised of 4 items: tone, posture, global coordination, manual dexterity. This factor is associated with the M-ABC, the MDR and the item "low endurance" of the Sensory Profile. CONCLUSION The SPSA is a relevant clinical tool to assess the severity of sensory-psychomotor clinical signs in order to describe the individual profiles of children with ASD. It represents a critical step in advancing knowledge of the complex and heterogeneous pattern of psychomotor development in autism. It could make a valuable contribution to the field, both in research and clinical practice.

Abstract
We consider the deformation of a thin elastic sheet which is stiff in traction but very soft in compression, as happens in the presence of wrinkling. We use the tension-field material model and explore numerically the response of a thin sheet containing multiple cracks of different geometries, when subjected to applied tension. With a single crack, the stress concentrates along a St. Andrew's cross-shaped pattern, whose branches extend from the crack tips to the corners of the domain; at a (small) distance r from the crack tip, the stress displays the usual r^{-1/2} stress singularity but with an unusual and nonuniversal angular dependence. A strong interaction between multiple cracks is reported and discussed: in particular, for certain configurations of the cracks, the tensile stiffness of a cracked sheet can be zero even though the sheet is made up of a single component.

Abstract
While fragility fractures (FFs) are one of the strongest predictors of subsequent osteoporotic fractures, it remains unclear whether low-trauma ankle fractures have this ability. The aim of the study was to identify the characteristics of patients with low-trauma ankle FFs who develop subsequent FFs. The OPTIMUS initiative is a strategy to improve osteoporosis treatment post-FF in orthopedic clinics. FRAX scores without BMD (FRAX-BMI) were calculated at time of inclusion. Recurrent FFs were recorded over a 48-month follow-up. All FFs were X-ray-confirmed. A total of 265 patients with initial ankle FF were included (190 women; mean age 62.8 ± 9.6 years), of whom 15 developed new FFs. Patients with ankle FFs had longer time until recurrence and lower 2-year incidence of recurrent FFs (3.2%) compared with those having wrist FFs (9.0%) or other initial FFs (9.6%), and 4-year incidence rates of 6.2, 13.4, and 15.3%, respectively (log-rank test, p = 0.001). With an ankle FF at inclusion, recurrent FFs were more frequent in patients with previous FF (6.2 per 100 patient-years; p < 0.01) or high-risk FRAX-BMI scores pre- or post-FF (2.4 or 2.0 per 100 patient-years, respectively; ns), compared to patients without any of these conditions (0.7 per 100 patient-years). Ankle FFs represent a clinical opportunity for identifying at-risk patients who should be targeted for treatment (previous FFs and/or high-risk FRAX). Because of mechanical factors and other contributors involved, ankle FFs themselves do not predict subsequent FFs overall, and their inclusion in FRAX-BMI risk calculation may thus not be warranted.

Abstract
UNLABELLED Interventions targeting patients with recent fragility fracture and their physician were most successful at initiating osteoporosis treatment during the first 12 months. This window of opportunity had already closed after 1 year. The reasons for declining or accepting the intensive intervention were explored in patients still untreated at 12 months. INTRODUCTION A fragility fracture (FF) event identifies patients most likely to benefit from osteoporosis treatment. Nonetheless, most FF patients go untreated. Our objective was to determine how long an incident FF remains a strong incentive to initiate osteoporosis treatment. METHODS A total of 1086 men and women over age 50 with a recent FF event were assigned to either standard care (SC), to minimal (MIN), or intensive (INT) interventions targeting patients and their family physician to initiate osteoporosis treatment. Inpatients with FF (mainly hip) evaluated by rheumatologists were also included in a specialized group (SPE; n = 324). At 1 year, untreated patients in both the SC and the MIN groups were offered an INT intervention. The cohort was followed through 48 months. A qualitative analysis of patient-centered decision-making associated with initiation of treatment was conducted. RESULTS In MIN and INT groups, osteoporosis treatment was initiated in 41.0 and 54.3% of untreated patients by 12 months, respectively, compared to 68.4% in SPE and 18.9% in SC groups; initiation rates drastically dropped thereafter. Over 4863 patient-years of follow-up, the rates of new FF were 3.4 per 100 patient-years, without significant differences between patients with initial major or minor FF, nor between control or intervention groups. Failure by patients and physicians to recognize FF as a sign of underlying bone disease contributed the most to lack of treatment. CONCLUSION While incident FFs are an ideal opportunity for starting osteoporosis treatment, 1 year later, the therapeutic window of opportunity has already closed.

Abstract
This study describes the kinetics of furan and furfural generation in a cake model, for the first time. These process-induced compounds impact safety and sensory aspects of baked products. Understanding their generation with regards to process dynamics will serve food quality design. However, the complexity of real products makes this task challenging. This work provides a novel approach to understand and model chemical reactivity by implementing an inert cake model (starch, water and cellulose), specifically designed for mimicking a sponge cake structure. The addition of reaction precursors (glucose and leucine) to follow Maillard and caramelization reactions, resulted in browning and generated considerable levels of furanic compounds (up to 17.61ng/g for furan and 38.99μg/g for furfural, dry basis). Multiresponse data modeling resulted in a kinetic model which adequately describes experimental concentrations and makes it possible to estimate the degradation of precursors and the behavior of two hypothetic intermediates.

Abstract
OBJECTIVES Fungi belonging to the Metarhizium anisopliae complex comprise ubiquitous arthropod pathogenic moulds used as mycopesticides. Rare cases of human infections due to M. anisopliae have been reported. We hypothesize misidentifications of fungal strains implicated in these cases or used in mycopesticides. METHODS A review of the literature was conducted to identify previously published cases. We collected some of these previous described strains and reported new cases, and a French mycopesticide containing M. anisopliae. All identifications were performed based on elongation factor-1α gene sequencing. RESULTS We report eight new cases of Metarhizium infection in humans (three from France and five from Australia). The strains isolated from these cases, and three others from already published cases and reported as M. anisopliae, were molecularly identified based on elongation factor-1α (Ef1-α) gene sequencing as follows: Metarhizium robertsii (six), Metarhizium guizhouense (three), Metarhizium brunneum (one) and Metarhizium pingshaense (one). CONCLUSIONS In this study, we report new human cases of Metarhizium infections, and, based on Ef-1α gene sequencing, we demonstrate the misidentification of species in case reports. We also correct the species identification of a strain reported as M. anisopliae used in a commercially available mycopesticide. According to our results, none of the strains from the human infection reports reviewed belongs to the species M. anisopliae.

Abstract
The Behavioral Summarized Evaluation is a rating scale specifically related to the assessment of autistic behaviors in children and young teenagers with Autism Spectrum Disorder, such as communication, social interaction and interests. It also facilitates progressive recording of the evolution of children with ASD involved in short-term therapeutical studies. In the absence of standardized tools to assess autistic behaviors and effects of therapeutics in Lebanon, the BSE-R validation is an urgent need. The purpose of this study is to validate the BSE-R to the Lebanese population. METHOD Specialized translators and clinicians ensured forward and backward translation of the scale into Arabic. The participants consisted of 100 children with ASD, diagnosed upon DSMIV-TR criterion (age range: 35 to 153 months, DS: 28.0). Fifty-eight had intellectual disability (ID). Scores of autism severity as measured by CARS1 (Schopler et al., 1980) varied from 20-58.5. Trained raters on recorded individual and group situations performed BSE-R ratings. RESULTS BSE-R for Lebanese was found to have excellent inter-rater reliability. The internal validity highlighted a main factor which describes the severity of core autistic behaviors related to social interactions and communication, and behavioral specificities and particular interests with an internal consistency of 0.91 in a one-to-one setting and 0.92 in group settings. External validity of the scale as measured by correlations with CARS and the age of the children showed that this main factor is essentially determined by ASD severity, not by the severity of ID. It was named "relational deficiency" according to the initial paper of Barthélémy et al. (1997). CONCLUSION BSE-R in Arabic is a practical tool, useful to all team members working with ASD children in Lebanon and the Arab countries. It will also allow future research based on reliable tools at an international level.

Abstract
We hypothesized that the difficulties of the child with autism originate from disorders of organization and regulation of actions according to environmental changes. Autism impoverishes general mental representation skills, which are the basis of symbolic play and the development of communication. Twenty-one children with autism were compared with 14 children with global intellectual impairment and 15 matched typically developing children, on both regulation of play activities and communication development. Regulation of play was very disordered in children with autism, with breaking off, dissociation and instability of actions. However, in directed play their actions were more structured and corresponded to a better developmental level. In addition, dysregulation was associated with delayed, heterogeneous development of communication skills. The results of this study are in line with our hypotheses and emphasize the role of symbolic play in differential diagnosis and the value of therapies based on regulation processes and symbolic play.

Abstract
Many studies have been devoted to adapting the design of gold nanoparticles to efficiently exploit their promising capability to enhance the effects of radiotherapy. In particular, the addition of magnetic resonance imaging modality constitutes an attractive strategy for enhancing the selectivity of radiotherapy since it allows the determination of the most suited delay between the injection of nanoparticles and irradiation. This requires the functionalization of the gold core by an organic shell composed of thiolated gadolinium chelates. The risk of nephrogenic systemic fibrosis induced by the release of gadolinium ions should encourage the use of macrocyclic chelators which form highly stable and inert complexes with gadolinium ions. In this context, three types of gold nanoparticles (Au@DTDOTA, Au@TADOTA and Au@TADOTAGA) combining MRI, nuclear imaging and radiosensitization have been developed with different macrocyclic ligands anchored onto the gold cores. Despite similarities in size and organic shell composition, the distribution of gadolinium chelate-coated gold nanoparticles (Au@TADOTA-Gd and Au@TADOTAGA-Gd) in the tumor zone is clearly different. As a result, the intravenous injection of Au@TADOTAGA-Gd prior to the irradiation of 9L gliosarcoma bearing rats leads to the highest increase in lifespan whereas the radiophysical effects of Au@TADOTAGA-Gd and Au@TADOTA-Gd are very similar.

Abstract
A new efficient type of gadolinium-based theranostic agent (AGuIX®) has recently been developed for MRI-guided radiotherapy (RT). These new particles consist of a polysiloxane network surrounded by a number of gadolinium chelates, usually 10. Owing to their small size (<5 nm), AGuIX typically exhibit biodistributions that are almost ideal for diagnostic and therapeutic purposes. For example, although a significant proportion of these particles accumulate in tumours, the remainder is rapidly eliminated by the renal route. In addition, in the absence of irradiation, the nanoparticles are well tolerated even at very high dose (10 times more than the dose used for mouse treatment). AGuIX particles have been proven to act as efficient radiosensitizers in a large variety of experimental in vitro scenarios, including different radioresistant cell lines, irradiation energies and radiation sources (sensitizing enhancement ratio ranging from 1.1 to 2.5). Pre-clinical studies have also demonstrated the impact of these particles on different heterotopic and orthotopic tumours, with both intratumoural or intravenous injection routes. A significant therapeutical effect has been observed in all contexts. Furthermore, MRI monitoring was proven to efficiently aid in determining a RT protocol and assessing tumour evolution following treatment. The usual theoretical models, based on energy attenuation and macroscopic dose enhancement, cannot account for all the results that have been obtained. Only theoretical models, which take into account the Auger electron cascades that occur between the different atoms constituting the particle and the related high radical concentrations in the vicinity of the particle, provide an explanation for the complex cell damage and death observed.

Abstract
The role of the sucrose transporter OsSUT1 in assimilate retrieval via the xylem, as a result of damage to and leakage from punctured phloem was examined after rusty plum aphid (Hysteroneura setariae, Thomas) infestation on leaves from 3-week-old rice (Oryza sativa L. cv Nipponbare) plants. Leaves were examined over a 1- to 10-day infestation time course, using a combination of gene expression and β-glucuronidase (GUS) reporter gene analyses. qPCR and Western blot analyses revealed differential expression of OsSUT1 during aphid infestation. Wide-field fluorescence microscopy was used to confirm the expression of OsSUT1-promoter::GUS reporter gene in vascular parenchyma associated with xylem elements, as well as in companion cells associated with phloem sieve tubes of large, intermediate and small vascular bundles within the leaf blade, in regions where the aphids had settled and were feeding. Of great interest was up-regulation of OsSUT1 expression associated with the xylem parenchyma cells, abutting the metaxylem vessels, which confirmed that OsSUT1 was not only involved in loading of sugars into the phloem under normal physiological conditions, but was apparently involved in the retrieval of sucrose leaked into the xylem conduits, which occurred as a direct result of aphid feeding, probing and puncturing of vascular bundles. The up-regulation of OsSUT1 in xylem vascular parenchyma thus provides evidence in support of the location within the xylem parenchyma cells of an efficient mechanism to ensure sucrose recovery after loss to the apoplast (xylem) after aphid-related feeding damage and its transfer back to the symplast (phloem) in O. sativa leaves.

Abstract
INTRODUCTION According to the literature, the treatment of retinopathy of Valsalva (VR) by laser is recommended when the macular hemorrhage has not regressed after 3 weeks. PATIENTS AND METHODS We report five cases of VR treated early (≤ 24 hours) by Nd:YAG laser membranotomy (LM). Clinical examination was performed before and after LM (D1, D7, M1, M3 and M6). Optical coherence tomography (OCT) analysis was performed to determine the precise location of the macular hemorrhage. RESULTS Good visual recovery was obtained early by LM with a stable outcome at 6 months. The hemorrhage was located under the internal limiting membrane (ILM) and posterior hyaloid in two patients and only under the ILM in three patients. DISCUSSION The literature review and our study confirm the good functional results for patients treated by LM for VR. Furthermore, very few side effects are reported with this type of treatment compared with the natural course of the disease, which may certainly regress spontaneously, but carries a risk of secondary preretinal fibrosis. However, to obtain optimal efficacy, the treatment should be carried out as soon as possible, in order to avoid clotting of the hematoma, preventing any subsequent evacuation by laser. CONCLUSION LM for VR is an effective, safe and inexpensive technique compared to the surgical management of these patients presenting with a persistant premacular hematoma after a period of observation.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The African medicinal plant Sutherlandia frutescens (L.) R.Br. (Fabaceae) is traditionally used to treat diabetes and has been shown to have anti-diabetic properties in animal models. The present study investigated the capacity of an aqueous extract of Sutherlandia frutescens to prevent insulin resistance (a precursor of type 2 diabetes) in a human liver cell culture and to identify genes regulated by Sutherlandia frutescens treatment. MATERIALS AND METHODS A combination of insulin and fructose was used to generate an in vitro model of insulin resistance in human liver cells to compare untreated control, insulin resistant and Sutherlandia frutescens treated insulin resistant cultures. Insulin resistance and its prevention by Sutherlandia frutescens were measured by glucose uptake, gluconeogenesis and lipid accumulation in the cell cultures. Changes in gene expression were quantified using the RT(2)Profiler(TM) PCR Array of 84 diabetes-related genes. RESULTS The insulin resistant Chang liver cells took up significantly less 2-[(3)H]-deoxyglucose (p<0.05) than controls, released more glucose into the culture medium (p<0.05) and accumulated more intracellular lipid (p<0.05). Simultaneous treatment with Sutherlandia frutescens prevented development of these insulin resistance parameters (p<0.05). A total of 27 potential gene targets of Sutherlandia frutescens were significantly up or down regulated in the Sutherlandia frutescens treated insulin resistant cells. The gene VAMP3, which plays a role in vesicle transport, was down-regulated by insulin resistance, and up-regulated by Sutherlandia frutescens. Twenty six other genes encoding vesicle transporters, receptors, signalling molecules, transcription factors, and metabolic enzymes were significantly regulated by Sutherlandia frutescens. CONCLUSION These results confirm that Sutherlandia frutescens can prevent insulin resistance in hepatocytes. The identified changes in gene expression indicate several potential mechanisms of anti-diabetic action for Sutherlandia frutescens, reflecting the multiple bioactive compounds previously identified in aqueous extracts of Sutherlandia frutescens.

Abstract
Although atypical change detection processes have been highlighted in the auditory modality in autism spectrum disorder (ASD), little is known about these processes in the visual modality. The aim of the present study was therefore to investigate visual change detection in adults with ASD, taking into account the salience of change, in order to determine whether this ability is affected in this disorder. Thirteen adults with ASD and 13 controls were presented with a passive visual three stimuli oddball paradigm. The findings revealed atypical visual change processing in ASD. Whereas controls displayed a vMMN in response to deviant and a novelty P3 in response to novel stimuli, patients with ASD displayed a novelty P3 in response to both deviant and novel stimuli. These results thus suggested atypical orientation of attention toward unattended minor changes in ASD that might contribute to the intolerance of change.

Abstract
OBJECTIVES In congenitally deaf children fit with a cochlear implant, little is known about the maturation of the auditory cortex. Cortical auditory evoked potentials are a useful methodology to study the auditory cortical system of children with cochlear implants. Nevertheless, these recordings are contaminated by a cochlear implant artifact. The objective of this study was to use independent component analysis to minimize the artifact of the cochlear implant to study cortical auditory evoked potentials. STUDY DESIGN Prospective study. METHOD A total of 5 children ranging in age from 21 to 49 months who were fitted with a cochlear implant for at least 6 months were included in this study. The stimuli were pure tones (750 Hz, 200 ms duration, 70 dB SPL) presented with an irregular interstimulus interval (1000-2000 ms) via loud speakers. The cortical auditory evoked potentials were recorded from 17 Ag-AgCl electrodes referenced to the nose. The peak latency and amplitude of each deflection culminating at the fronto-central and temporal sites were analyzed. MAIN OUTCOME MEASURES The P100-N250 peak latencies and amplitudes of the cortical auditory evoked potentials recorded from children fitted with cochlear implants. Scalp map potentials distributions were done for each child for the N250 wave. RESULTS The use of independent component analysis permitted to minimize the cochlear implant artifact for the five children. Cortical auditory evoked potentials were recorded at fronto-central and temporal sites. Scalp map potentials distributions for the N2 wave showed activation of temporal generators contralateral at the CI for the five children. CONCLUSION This preliminary electrophysiological study confirms the value and the limits of independent component analysis. It could allow longitudinal studies in cochlear implant users to examine the maturation of auditory cortex. It could also be used to identify objective cortical electrophysiological measures to help the fitting of CIs in children.
