Abstract
Differential deposition by DC magnetron sputtering was applied to correct for figure errors of X-ray mirrors to be deployed on low-emittance synchrotron beamlines. During the deposition process, the mirrors were moved in front of a beam-defining aperture and the required velocity profile was calculated using a deconvolution algorithm. The surface figure was characterized using conventional off-line visible-light metrology instrumentation (long trace profiler and Fizeau interferometer) before and after the deposition. WSi2 was revealed to be a promising candidate material since it conserves the initial substrate surface roughness and limits the film stress to acceptable levels. On a 300 mm-long flat Si mirror the average height errors were reduced by a factor of 20 down to 0.2 nm root mean square. This result shows the suitability of WSi2 for differential deposition. Potential promising applications include the upgrade of affordable, average-quality substrates to the standards of modern synchrotron beamlines.

Abstract
Unicentric Castleman disease (UCD) is a lymphoproliferative disease of unknown cause. Paraneoplastic pemphigus (PNP) is a major complication shown to be associated with a poor prognosis, with particular severity in patients with bronchiolitis obliterans (BO). This study describes the clinical and biological characteristics of UCD-PNP patients in a large Western cohort. A total of 148 patients diagnosed with UCD were identified, including 14 patients with a defined PNP. PNP was significantly associated with myasthenia gravis (MG) and FDC sarcoma during follow-up (FDCS). PNP was also significantly associated with reduced survival. These data, together with a multivariate analysis by principal components, led to the identification of UCD-PNP as a group at risk of MG, FDCS and death. PDGFRB sequencing performed on UCD lesions from six patients found the gain-of-function p.N666S variant in two. Interestingly, both patients had hyaline-vascular UCD subtype, were in the UCD-PNP subgroup and had FDCS. Sera from 25 UCD-PNP patients and 6 PNP patients without UCD were tested for PNP-associated autoantibodies. Sera from UCD-PNP patients had a strong reactivity against the N-terminal domain of recombinant periplakin (rPPL, 82%) and showed reactivity against at least two domains of rPPL. These features were not found in patients with UCD alone or in the PNP group without UCD. These data indicate that UCD-PNP patients belong to a subgroup sharing strong clinical and biological identity that might help to decipher the different dynamics of UCD natural history.

Abstract
BACKGROUND Data from the PEXIVAS trial challenged the role of plasma exchange (PLEX) in ANCA-associated vasculitides (AAV). We aimed to describe kidney biopsy from patients with AAV treated with PLEX, evaluate whether histopathologic findings could predict kidney function, and identify which patients would most benefit from PLEX. METHODS We performed a multicenter, retrospective study on 188 patients with AAV and AKI treated with PLEX and 237 not treated with PLEX. The primary outcome was mortality or KRT at 12 months (M12). RESULTS No significant benefit of PLEX for the primary outcome was found. To identify patients benefitting from PLEX, we developed a model predicting the average treatment effect of PLEX for an individual depending on covariables. Using the prediction model, 223 patients had a better predicted outcome with PLEX than without PLEX, and 177 of them had >5% increased predicted probability with PLEX compared with without PLEX of being alive and free from KRT at M12, which defined the PLEX-recommended group. Risk difference for death or KRT at M12 was significantly lower with PLEX in the PLEX-recommended group (-15.9%; 95% CI, -29.4 to -2.5) compared with the PLEX not recommended group (-4.8%; 95% CI, 14.9 to 5.3). Microscopic polyangiitis, MPO-ANCA, higher serum creatinine, crescentic and sclerotic classes, and higher Brix score were more frequent in the PLEX-recommended group. An easy to use score identified patients who would benefit from PLEX. The average treatment effect of PLEX for those with recommended treatment corresponded to an absolute risk reduction for death or KRT at M12 of 24.6%. CONCLUSIONS PLEX was not associated with a better primary outcome in the whole study population, but we identified a subset of patients who could benefit from PLEX. However, these findings must be validated before utilized in clinical decision making.

Abstract
BACKGROUND Immune-mediated thrombotic thrombocytopenic purpura (iTTP) is a rare life-threatening thrombotic microangiopathy requiring urgent therapeutic plasma exchange (TPE). However, the exact impact of a slight delay in TPE initiation on the subsequent patients' outcome is still controversial. AIM We aimed to study the frequency, short-term neurological consequences, and determinants of diagnostic delay in iTTP. METHODS We conducted a retrospective monocentric study including patients with a first acute episode of iTTP (2005-2020) classified into 2 groups: delayed (>24h from first hospital visit, group 1) and immediate diagnosis (≤24h, group 2). RESULTS Among 42 evaluated patients, 38 were included. Eighteen cases (47%) had a delayed diagnosis (median: 5 days). The main misdiagnosis was immune thrombocytopenia (67%). The mortality rate was 5% (1 death in each group). Neurological events (stroke/TIA, seizure, altered mental status) occurred in 67% vs 30% patients in group 1 and 2, respectively (p = 0.04). Two patients in group 1 exhibited neurological sequelae. The hospital length of stay was longer in group 1 (p = 0.02). At the first hospital evaluation, potential alternative causes of thrombocytopenia were more prevalent in group 1 (33% vs 5%, p = 0.04). Anemia was less frequent in group 1 (67% vs 95%, p = 0.04). All patients had undetectable haptoglobin levels. By contrast, 26% of schistocytes counts were <1%, mostly in group 1 (62% vs 11%, p = 0.01). CONCLUSION Diagnostic delay is highly prevalent in iTTP, with a significant impact on short-term neurological outcome. In patients with profound thrombocytopenia, the thorough search for signs of incipient organ dysfunction, systematic hemolysis workup, and proper interpretation of schistocytes count are the key elements of early diagnosis of TTP.

Abstract
Aims To identify factors associated with vascular events in patients with giant cell arteritis (GCA). Methods We performed a retrospective study of GCA patients diagnosed over a 20-year-period, who all underwent vascular imaging evaluation at diagnosis. Symptomatic vascular events were defined as the occurrence of any aortic event (aortic dissection or symptomatic aortic aneurysm), stroke, myocardial infarction, limb or mesenteric ischemia and de novo lower limbs arteritis stage 3 or 4. Patients with symptomatic vascular event (VE+) and without were compared, and risk factors were identified in a multivariable analysis. Results Thirty-nine (15.4%) of the 254 included patients experienced at least one symptomatic vascular event during follow-up, with a median time of 21.5 months. Arterial hypertension, diabetes, lower limbs arteritis or vascular complication at diagnosis were more frequent in VE+ patients (p < 0.05), as an abnormal computed tomography (CT)-scan at diagnosis (p = 0.04), aortitis (p = 0.01), particularly of the descending thoracic aorta (p = 0.03) and atheroma (p = 0.03). Deaths were more frequent in the VE+ group (37.1 versus 10.3%, p = 0.0003). In multivariable analysis, aortic surgery [hazard ratio (HR): 10.46 (1.41-77.80), p = 0.02], stroke [HR: 22.32 (3.69-135.05), p < 0.001], upper limb ischemia [HR: 20.27 (2.05-200.12), p = 0.01], lower limb ischemia [HR: 76.57 (2.89-2027.69), p = 0.009], aortic atheroma [HR: 3.06 (1.06-8.82), p = 0.04] and aortitis of the descending thoracic aorta on CT-scan at diagnosis [HR: 4.64 (1.56-13.75), p = 0.006] were independent predictive factors of a vascular event. Conclusion In this study on GCA cases with large vessels imaging at diagnosis, aortic surgery, stroke, upper or lower limb ischemia, aortic atheroma and aortitis of the descending thoracic aorta on CT-scan, at GCA diagnosis, were independent predictive factors of a vascular event. Plain language summary Risk factors for symptomatic vascular events in giant cell arteritisThis study was performed to identify the risk factors for developing symptomatic vascular event during giant cell arteritis (GCA) because these are poorly known.We performed a retrospective study of GCA patients diagnosed over a 20-year-period, who all underwent vascular imaging evaluation at diagnosis.Patients with symptomatic vascular event (VE+) and without (VE-) were compared, and risk factors were identified in a multivariable analysis.Thirty-nine patients experienced at least one symptomatic vascular event during follow-up, with a median time of 21.5 months.Arterial hypertension, diabetes, lower limbs arteritis or vascular complication at diagnosis were significantly more frequent in VE+ patients, as an abnormal CT-scan at diagnosis, aortitis, particularly of the descending thoracic aorta and atheroma. Deaths were more frequent in the VE+ group.Among 254 GCA patients, 39 experienced at least one vascular event during follow-up.Aortic surgery, stroke, upper and lower limb ischemia were vascular event risk factors.Aortic atheroma and descending thoracic aorta aortitis on CT-scan were vascular event risk factors.This study on GCA cases with large vessels imaging at diagnosis, showed that aortic surgery, stroke, upper or lower limb ischemia, aortic atheroma and aortitis of the descending thoracic aorta on CT-scan, at GCA diagnosis, were independent predictive factors of a vascular event.

Abstract
Objective To assess the efficacy and tolerance of tocilizumab (TCZ) in giant cell arteritis (GCA) patients over 80. Method GCA patients over 80 years old from the French Study Group for Large Vessel Vasculitis register who received TCZ were analyzed. Results Twenty-one GCA patients (median age 84 [81–90] years old, including nine over 85) received TCZ for the following nonexclusive reasons: glucocorticoid (GC)-sparing effect in 14, relapsing disease in 8, disease severity in 4, and/or failure of another immunosuppressant in 4. TCZ was introduced with GCs at diagnosis in 6 patients and at 8 [3–37] months after GC initiation in 15 others. After a median delay of 8 [2–21] months post-TCZ introduction, 14 (67%) patients were able to definitively stop GCs, including 6 who were GC-dependent before TCZ. At the last follow-up (median 20 [3–48] months), 11 (52%) patients had definitively stopped TCZ, and 2 additional patients had stopped but relapsed and resumed TCZ. Seven (33%) patients experienced 11 adverse events: hypercholesterolemia in 4 patients; infections, i.e., pyelonephritis, bronchitis, and fatal septic shock associated with mesenteric infarction following planned surgery (GCs were stopped for 1 year and TCZ infusions for 2 months), respectively, in 3 patients; moderate thrombocytopenia and moderate neutropenia in 2 patients; and a 5-fold increase in transaminase levels in another that improved after TCZ dose reduction. Conclusion TCZ remains a valuable GC-sparing option in the oldest GCA patients with an interesting risk-benefit ratio. Mild-to-moderate adverse events were observed in one-third of patients.

Abstract
Background: Giant cell arteritis (GCA) is the most common systemic vasculitis. Relapses are frequent. The aim of this study was to identify relapse risk factors in patients with GCA with complete large-vessel imaging at diagnosis. Methods: Patients with GCA followed in our institution between April 1998 and April 2018 were included retrospectively. We included only patients who had undergone large vascular imaging investigations at diagnosis by computed tomography (CT)-scan and/or positron emission tomography (PET)-scan and/or angio-magnetic resonance imaging (MRI). Clinical, biological, and radiological data were collected. Relapse was defined as the reappearance of GCA symptoms, with concomitant increase in inflammatory markers, requiring treatment adjustment. Relapsing patients (R) and non-relapsing patients (NR) were compared. Relapse and multiple relapses (>2) risk factors were identified in multivariable Cox analyses. Results: This study included 254 patients (73.2% women), with a median age of 72 years at diagnosis and a median follow up of 32.5 months. At diagnosis, 160 patients (63%) had an inflammatory large-vessel involvement on imaging, 46.1% (117 patients) relapsed at least once, and 21.3% (54 patients) had multiple relapses. The median delay of first relapse after diagnosis was 9 months. The second relapse delay was 21.5 months. NR patients had more stroke at diagnosis than R (p = 0.03) and the brachiocephalic trunk was involved more frequently on CT-scan (p = 0.046), as carotids (p = 0.02) in R patients. Multivariate Cox model identified male gender [hazard ratio (HR): 0.51, confidence interval (CI) (0.27–0.96), p = 0.04] as a relapse protective factor, and peripheral musculoskeletal manifestations [HR: 1.74 (1.03–2.94), p = 0.004] as a relapse risk factor. Peripheral musculoskeletal manifestations [HR: 2.78 (1.23–6.28), p = 0.014], negative temporal artery biopsy [HR: 2.29 (1.18–4.45), p = 0.015], large-vessel involvement like upper limb ischemia [HR: 8.84 (2.48–31.56), p = 0.001] and inflammation of arm arteries on CT-scan [HR: 2.39 (1.02–5.58), p = 0.04] at diagnosis were risk factors of multiple relapses. Conclusion: Male gender was a protective factor for GCA relapse and peripheral musculoskeletal manifestations appeared as a relapsing risk factor. Moreover, this study identified a particular clinical phenotype of multi-relapsing patients with GCA, characterized by peripheral musculoskeletal manifestations, negative temporal artery biopsy, and large-vessel involvement with upper limb ischemia or inflammation of arm arteries. Plain language Summary At giant cell arteritis diagnosis, large-vessel inflammatory involvement is predictive of multiple relapses

Abstract
The surface figure error of a hard X-ray mirror was improved by combining differential deposition and off-line metrology tools. Thin Cr layers were deposited on flat substrates by DC magnetron sputtering. The substrates were moved in front of a beam-defining aperture. The required velocity profile was calculated using a deconvolution algorithm. The Cr thickness profiles were measured directly using hard X-ray reflectivity data. The surface figure was characterized using conventional visible-light metrology instrumentation (long trace profiler) before and after the deposition. The method converges quickly, and after two iterations the mirror surface figure had improved by a factor of 7. The surface roughness evolves with increasing Cr thickness and deteriorates the quality of subsequent multilayer coatings. The mirror curvature can change upon coating, which complicates the interpretation of the surface metrology data. In this context, the role of layer stress is discussed. Potential improvements of the process are also proposed.

Abstract
Optical metrology and polishing techniques are continuously evolving to satisfy the increasingly stringent specifications required for X-ray optical components for synchrotron and free-electron laser light source beamlines. For both spherical and aspherical geometries, the most demanding applications may have target residual figure errors close to 1 nm. To achieve such specifications and maintain them in the optomechanical mount, it is critical to develop methods capable of measuring the topography of the optical surface over the clear aperture of the mirror. The European Synchrotron Radiation Facility optical metrology laboratory has developed a stitching tool initially aimed at measuring long flat mirrors up to 1 m long with a Fizeau interferometer. The system is routinely used providing 2D maps of the optical surface. The instrument capabilities have been extended to characterize moderately curved optics using a transmission flat element, and results obtained on a high quality spherical mirror with 120 m of radius of curvature are presented. As a novel approach of stitching application, the technique has been used to improve the measurement accuracy of the Fizeau interferometer when measuring short plane mirrors. Acquisition of 2D topographies on a short plane mirror by micro-stitching interferometry is also presented and discussed.

Abstract
The combination of complementary techniques in the characterization of catalysts under working conditions is a very powerful tool for an accurate and in-depth comprehension of the system investigated. In particular, X-ray absorption spectroscopy (XAS) coupled with diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) and mass spectroscopy (MS) is a powerful combination since XAS characterizes the main elements of the catalytic system (selecting the absorption edge) and DRIFTS monitors surface adsorbates while MS enables product identification and quantification. In the present manuscript, a new reactor cell and an experimental setup optimized to perform time-resolved experiments on heterogeneous catalysts under working conditions are reported. A key feature of this setup is the possibility to work at high temperature and pressure, with a small cell dead volume. To demonstrate these capabilities, performance tests with and without X-rays are performed. The effective temperature at the sample surface, the speed to purge the gas volume inside the cell and catalytic activity have been evaluated to demonstrate the reliability and usefulness of the cell. The setup capability of combining XAS, DRIFTS and MS spectroscopies is demonstrated in a time-resolved experiment, following the reduction of NO by Rh nanoparticles supported on alumina.

Abstract
BACKGROUND Reliable evaluation of patients with unresponsive wakefulness syndrome (UWS) or in a minimally conscious state (MCS) remains a major challenge. It has been suggested that the expression of residual cerebral function could be improved by allowing patients to listen to their favourite music. However, the potential effect of music on behavioural responsiveness, as well as the effect of preferred stimuli in other sensory modalities (e.g. olfaction), remain poorly understood. OBJECTIVE The aim of our study was to investigate the effect of sensory modality (auditory versus olfactory) and preference (preferred versus neutral) of the test stimuli on patients' subsequent performance on the Coma Recovery Scale-Revised (CRS-R). RESEARCH DESIGN Within-subject design because of inter-individual differences between patients. METHODS AND PROCEDURES We studied four items from the CRS-R (visual pursuit using a mirror, auditory localization of the own name and two movements to command) in 13 patients (7 MCS; 6 UWS). MAIN OUTCOMES AND RESULTS Auditory stimuli triggered higher responsiveness compared to olfactory stimuli, and preferred stimuli were followed by higher scores than did neutral stimuli. CONCLUSIONS Findings suggest that preferred auditory stimuli at the bedside contribute to the expression of residual function and could improve the diagnostic assessment.

METHODS Patients from 11 French internal medicine departments were retrospectively included. Aortitis was defined by aortic wall thickening >2mm and/or an aortic aneurysm on CT-scan, associated to inflammatory syndrome. Patients with GCA had at least 3 ACR criteria. Aortic events (aneurysm, dissection, aortic surgeries) were reported, and free of aortic events-survival were compared. RESULTS Among 191 patients with non-infectious aortitis, 73 with GCA and 44 with IA were included. Patients with IA were younger (65 vs 70 years, p=0.003) and comprised more past/current smokers (43 vs 15%, p=0.0007). Aortic aneurisms were more frequent (38% vs 20%, p=0.03), and aortic wall thickening was more pronounced in IA. During follow-up (median=34 months), subsequent development of aortic aneurysm was significantly lower in GCA when compared to IA (p=0.009). GCA patients required significantly less aortic surgery during follow-up than IA patients (p=0.02). Mean age, sex ratio, inflammatory parameters, and free of aortic aneurism survival were equivalent in patients with IA ≥ 60 years when compared to patients with GCA-related aortitis. CONCLUSIONS IA is more severe than aortitis related to GCA, with higher proportions of aortic aneurism at diagnosis and during follow-up. IA is a heterogeneous disease and its prognosis is worse in younger patients <60 years. Most patients with IA ≥ 60 years share many features with GCA-related aortitis.

Abstract
INTRODUCTION Jaccoud's arthropathy (JA) is a chronic and non-erosive deforming arthropathy, usually affecting the hands. JA pathophysiology is poorly known but involves periarticular structures such as tendons and the joint capsule. JA is associated with various conditions including the connective tissue disease, especially systemic lupus erythematosis. JA has been rarely described and studied in systemic sclerosis. CASE REPORTS We report the clinical histories of 3 patients with systemic sclerosis (ScS) who developed JA. One patient had a systemic limited disease and the 2 others a cutaneous limited disease ; mean age of the patients was 79.3 years. Systemic sclerosis was diagnosed respectively 19, 1 and 21 years prior to the development of JA. One of the 3 patients had a past clinical history of discoid lupus. For 1 out of the 3 patients, JA appeared whereas the ScS was completely stable. The disease was still active in the 2 remaining patients, with concurrent pulmonary hypertension diagnosis. Deformities increased during years (Z thumbs, ulnar deviation), leading to mild to severe disability. No benefit from either prednisone (n=2) or a combination of prednisone and methotrexate (n=1) was obtained. CONCLUSION We described 3 cases of Jaccoud's arthropathy among our scleroderma cohort of 296 patients (1%). This arthropathy worsens hand functional disability. Its pathophysiology is unknown and optimal therapeutic approach remains to establish.

Abstract
The European Synchrotron Radiation Facility has recently made available to the user community a facility totally dedicated to Time-resolved and Extreme-conditions X-ray Absorption Spectroscopy--TEXAS. Based on an upgrade of the former energy-dispersive XAS beamline ID24, it provides a unique experimental tool combining unprecedented brilliance (up to 10(14) photons s(-1) on a 4 µm × 4 µm FWHM spot) and detection speed for a full EXAFS spectrum (100 ps per spectrum). The science mission includes studies of processes down to the nanosecond timescale, and investigations of matter at extreme pressure (500 GPa), temperature (10000 K) and magnetic field (30 T). The core activities of the beamline are centered on new experiments dedicated to the investigation of extreme states of matter that can be maintained only for very short periods of time. Here the infrastructure, optical scheme, detection systems and sample environments used to enable the mission-critical performance are described, and examples of first results on the investigation of the electronic and local structure in melts at pressure and temperature conditions relevant to the Earth's interior and in laser-shocked matter are given.

Abstract
INTRODUCTION Pulmonary hypertension (PH) may occur in patients with antisynthetase syndrome (ASS) but this association is poorly studied. In this article, we report 4 new cases of PH associated with ASS, and we discuss PH mechanisms in this specific disease. CASES Four patients (3 females, 1 male) with confirmed ASS associated with anti-Jo1 (n=3), anti-PL7 (n=1), and anti-Ro52 (n=3) antibodies were analyzed. They presented with subacute dyspnea in average ten years after they were first diagnosed as ASS. Diagnosis of pre-capillary PH was made (mean of mPAP: 34mmHg): PAH (n=1), group 3 PH (n=2) and PH associated to hyperthyroidism (n=1). Among three patients who received specific PAH therapy, two had significant improvement in both clinical and hemodynamic parameters. CONCLUSION During ASS, PH may occur in 5 to 10 % of cases, caused by various mechanisms. Unexplained dyspnea may be due to PH among ASS patients.

Abstract
Several studies have shown that music can boost cognitive functions in normal and brain-damaged subjects. A few studies have suggested a beneficial effect of music in patients with a disorder of consciousness but it is difficult to conclude since they did not use quantified measures and a control condition/group. The aim of the present study was to compare the effect of music to that of a continuous sound on the relational behavior of patients in a minimally conscious state (MCS). Behavioral responses of six MCS patients were evaluated using items from the Coma Recovery Scale-Revised. Weekly evaluation sessions were carried out, over four weeks, under two conditions: following the presentation of either the patient's preferred music, or following a continuous sound (control condition). Qualitative and quantitative analyses showed that twelve of the eighteen sessions (66.6%) showed a better result for the music condition than for the control condition. This new protocol suggests that preferred music has a beneficial effect on the cognitive abilities of MCS patients. The results further suggest that cerebral plasticity may be enhanced in autobiographical (emotional and familiar) contexts. These findings should now be further extended with an increased number of patients to further validate the hypothesis of the beneficial effect of music on cognitive recovery.

Abstract
The aim of this study is to assess the long-term effectiveness and safety of IL1Ra in Schnitzler syndrome (SchS). Between 2010 and 2012, we performed a nationwide survey among French internal medicine departments to identify SchS patients. We retrospectively analyzed the long-term efficacy and safety of IL1Ra and the outcome of patients that did not receive this treatment. Forty-two patients were included in the study, 29 of whom received IL1Ra. The mean age at disease onset was 59.9years. Disease manifestations included urticaria (100%), fever (76%), bone/joint pain (86%), bone lesions (76%), anemia (67%), and weight loss (60%). The monoclonal gammopathy was overwhelmingly IgM kappa (83%). The mean follow-up was 9.5years (range: 1.6-35). Two patients developed Waldenström's macroglobulinemia and one developed AA amyloidosis. All of the 29 patients who received IL1Ra responded dramatically. After a median follow-up of 36months (range: 2-79), the effectiveness remained unchanged. All patients remained on anti-IL-1 therapy. Twenty-four patients (83%) went into complete remission and five (17%) into partial remission. Three patients experienced grade 3-4 neutropenia. Six patients developed severe infections. No lymphoproliferative diseases occurred while on IL1Ra. When last seen, all patients without anakinra had an active disease with variable impact on their quality of life. Their median corticosteroids dosage was 6mg/d (range: 5-25). IL1Ra is effective in SchS, with a sharp corticosteroid-sparing effect. Treatment failures should lead to reconsider the diagnosis. Long-term follow-up revealed no loss of effectiveness and a favorable tolerance profile. The long-term effects on the risk of hemopathy remain unknown.

Abstract
OBJECTIVE Increasing prevalence of obesity particularly affects underprivileged families and children. This study aimed to estimate the efficiency of an obesity prevention program for school-aged children in deprived urban areas. METHODS This was an intervention trial with a before-and-after comparison of a cohort of school-aged children in preschool and primary school in three deprived urban areas in Grenoble, France. All school-aged children in the first and third year of preschool and the third year of primary school during the 2008-2009 and 2009-2010 school years, whose parents agreed to participate in the study, were included. Children were seen again 2 years later. The staff of the school health service measured and weighed the children during a medical check-up, thus determining their body mass index (BMI) and Z score. A school doctor suggested specific care to the parents of overweight children. A lifestyle questionnaire was completed. The primary outcome was changes in BMI and the Z score over 2 years. The secondary outcome was changes in lifestyle and eating habits. RESULTS A total of 2434 children were included in the screening campaign. Of the 2434 children included in screening, 1824 children were reviewed and evaluated at 2 years. At inclusion, overweight prevalence increased with age, from 6.4% in the first year of preschool to 21.9% in the third year of primary school. More than 60% of overweight children had a high social vulnerability score. Prevalence of overweight increased from 13.8% to 21.5% in 2 years in the entire cohort (P<0.001). In the 252 overweight children, the mean BMI increased from 20 kg/m(2) to 21.8 kg/m(2) (P<0.001), as did the mean Z score, which increased from 2.72 to 2.9 (P<0.001). There was no significant interaction depending on whether the family physician was in private practice or employed by a health center. According to their eating habits, fewer of the overweight children had a snack in the morning and more had a school lunch. More than half of the children thought they had improved their eating habits. They played more sports (30% versus 49.5%). CONCLUSION This study failed to demonstrate that incentive for medical management of excess weight had an effect on the short-term (2 years) evolution of the children's corpulence.

Abstract
The aim of this study is to investigate long-term outcome of symptomatic type 1 cryoglobulinemia (CG) and its determinants. Retrospective cohort study was conducted in two French University Hospitals. Patients with type 1 CG were identified using laboratory databases. Inclusion criterion was the presence of persistent symptoms of CG. Among 227 screened patients, 36 were included. Skin or vasomotor symptoms were the most frequent features (75%). Nephropathy and neuropathy occurred in 30% and 47% of cases, respectively. The underlying B cell disease (BCD) was a nonmalignant monoclonal gammopathy (NMMG) in 13 (36%) and a hematologic malignancy (HM) in 23 (64%; Waldenstrom macroglobulinemia (WM) in 12, low-grade non-Hodgkin lymphoma (NHL) in 6, multiple myeloma (MM) in 4, and chronic lymphocytic leukemia in 1 patient. Severe manifestations affected half the patients and were more frequent with IgG (82 vs. 30% (P = 0.006)). At last follow-up, 64% of patients had suffered no hematologic manifestation. Potent chemotherapeutic regimens were mainly used in HM. For patients with NMMG, WM, or NHL, fludarabine or rituximab-based regimens appeared to yield better responses. Five-year survival rate was 82%. In multivariate analysis, mortality was significantly higher in older patients (HR: 1.17 per year [95% CI: 1.06-1.28], P = 0.001) and those with nephropathy (HR: 8.9 [95% CI: 1.9-43], P = 0.006). Kidney disease, infections, Richter's transformation, and second malignancies were important sources of morbi-mortality. Despite its limitations, this series provide novel information regarding type 1 CG. Further studies are needed to improve its management. To date, therapeutic strategy should be tailored according to patient's characteristics (age, comorbidities, underlying BCD), and therapeutic target.

Abstract
Diseases affecting the alveolar-capillary membrane or the capillary blood vessels can impair pulmonary gas exchanges and lung diffusion. The single-breath transfer factor of the lung for carbon monoxide (TL,CO) is the classical technique for measuring gas transfer from the alveolus to the pulmonary capillary blood. Pulmonary gas exchanges can also be explored by the transfer factor of the lung for nitric oxide (TL,NO). TL,NO represents a better index for the diffusing capacity of the alveolar-capillary membrane whereas TL,CO is more influenced by red blood cell resistance. Membrane diffusing capacity (DM) and pulmonary capillary blood volume (Vc) derivated from TL,CO and TL,NO by the Roughton-Forster equation can give additional insights into pulmonary pathologies. The clinical impact of the CO/NO transfer has still to be precised even if this measurement seems to provide an alternative way of investigating the alveolar membrane and the blood reacting with the gas.
