Abstract
In recent decades, preterm birth (PTB) has become a significant research focus in the healthcare field, as it is a leading cause of neonatal mortality worldwide. Using five independent study cohorts including 1290 vaginal samples from 561 pregnant women who delivered at term (n = 1029) or prematurely (n = 261), we analysed vaginal metagenomics data for precise microbiome structure characterization. Then, a deep neural network (DNN) was trained to predict term birth (TB) and PTB with an accuracy of 84.10% and an area under the receiver operating characteristic curve (AUROC) of 0.875 ± 0.11. During a benchmarking process, we demonstrated that our DL model outperformed seven currently used machine learning algorithms. Finally, our results indicate that overall diversity of the vaginal microbiota should be taken in account to predict PTB and not specific species. This artificial-intelligence based strategy should be highly helpful for clinicians in predicting preterm birth risk, allowing personalized assistance to address various health issues.

Abstract
Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease affecting young people. It has a profound impact on their physical, mental and social lives, leading to long-term disability. With the growing awareness of the importance of sleep in all areas of functioning in young people, an emerging literature has drawn attention to the role of sleep in the pathogenesis of JIA. Sleep disturbances in children and adolescents with JIA arise from a wide range of symptoms and pathways, leading to a vicious cycle that exacerbates subclinical inflammation, symptoms and disease progression. Putative factors contributing to sleep disturbances include chronic inflammation, JIA-associated sleep disorders, JIA symptoms (e.g. pain), psychological comorbidities and potential circadian disruption, which may be exacerbated by the transition to adolescence. Here, we review these pathways and advocate key strategies and alternatives for sleep management in young people with JIA in clinical settings. We identify gaps in knowledge and suggest future directions to improve our understanding of JIA sleep disorders, including clinical trials investigating potential strategies to improve sleep health in this young population.

Abstract
BACKGROUND Myocardial work (MW) is a new echocardiographic tool with a high sensitivity to detect early and subtle alterations of myocardial function. We aimed to evaluate the late effects of anthracyclines by assessing the global and segmental MW and intraventricular mechanical dispersion from speckle tracking echocardiography in childhood lymphoma survivors (CLS). METHODS Thirty-one young adults including CLS and age-matched healthy controls were enrolled. All underwent echocardiography including an evaluation of left ventricular (LV) morphology and regional function. We assessed LV longitudinal (differentiating sub-endocardial and sub-epicardial layers), circumferential strains and twist, global and regional MW index (MWI). LV mechanical dispersion was assessed from the time dispersion of LV longitudinal strain, from myocardial wasted work (MWW) and myocardial work efficiency (MWE). RESULTS The longitudinal strains both at the level of the sub-endocardium and sub-epicardium were reduced in CLS compared to controls. The global MWI was also decreased (1668 ± 266 vs 1870 ± 264%.mmHg in CLS patients and controls, respectively, p < 0.05), especially on the apical segments. An increase of LV intraventricular mechanical dispersion was observed in CLS. MWW and MWE remained unchanged compared to controls. CONCLUSION Our results strongly support that cardiac remodeling is observed in CLS, characterized by a decrease in MW and an increase in LV mechanical dispersion. The apex is specifically altered, but its clinical significance remains uncertain. MW as a complement to strain seems interesting in cancer survivors to detect myocardial dysfunction at early stage and adapt their follow-up.

Abstract
BACKGROUND AND AIMS In adolescents with obesity, a left atrial (LA) enlargement has been reported. However, data regarding its function and its stiffness are missing. The aim of this study was to describe LA morphology and function, using speckle-tracking echocardiography (STE) and to explore their potential determinants in adolescents with obesity. METHODS Twenty-eight adolescent women with obesity (13.2 ± 1.4 yr) with an illness duration of 130 ± 27 months and 33 controls (14.1 ± 2.0 yr) underwent a resting echocardiography including an analysis of left ventricular (LV) and LA morphologies and strains. A fasting venous blood sample was performed to biochemical determinations including inflammation markers. RESULTS LA volume and stiffness index were increased in adolescents with obesity compared to controls. LA reservoir, conduit and booster pump functions were not different between groups. By stepwise forward multivariate regression analyses, systolic blood pressures, cardiac output and sedimentation rate were the independent determinants of LA volume (p < 0.0001, β-coefficient = 0.460) whereas only the body mass index was an independent determinant of LA stiffness (p = 0.003, β-coefficient = 0.413). CONCLUSION In adolescents with obesity, we observed a specific LA remodeling, including higher volume and lower stiffness, which could constitute early signs of an altered LV diastolic function.

Abstract
A threshold of 50 μg fecal calprotectin per g stool sample (μg/g) is commonly used to diagnose chronic inflammatory bowel disease in adult patients and children over 4 years of age. In younger children, fecal calprotectin values are physiologically increased. For the first time, the objective of our study was to establish reference ranges in newborns for the measurement of meconium calprotectin with an automated assay (Liaison® XL, DiaSorin). A prospective study was conducted in 2022 in the Maternity Unit of the Clermont-Ferrand University Hospital, with the inclusion of full-term newborns without intestinal involvement. The quantitative automated Liaison® XL calprotectin assay was assessed on a panel of meconium samples. In our cohort of 132 term neonates, calprotectin values ranged from 21 to 855 μg/g of meconium (2,5th to 97.5th percentile) and the median value was 194 μg/g. In our cohort, only sex-related differences were observed for calprotectin values. No significant differences were found for the other factors studied (maternal or neonatal). Because of inter-individual variability, a sequential measurement of newborn calprotectin from meconium should be considered.

Abstract
Pediatric diarrhea is a major public health problem worldwide. In France, continuous surveillance shows a winter epidemic peak and a more modest summer recrudescence. Few studies describe the infectious agents responsible for pediatric summer diarrhea in France. The objectives were to estimate the prevalence of infectious diarrhea and describe the pathogens responsible for summer diarrhea in children; and to describe common factors that can be used as guidance on the etiology of these diarrheas. A cross-sectional, single-center, epidemiological observational study was conducted in the pediatric emergency department of a French hospital between June and September in 2019 and 2020. Multiplex gastrointestinal pathogen panels were used for diagnostics. A multiple correspondence analysis was used to determine profiles of patients. A total of 95 children were included, of whom 82.1% (78/95) were under five years old. The prevalence of infectious summer diarrhea was 81.1% (77/95, 95%CI 71.7-88.4%). A total of 126 infectious agents were detected (50.0% bacteria, 38.1% viruses, 11.9% parasites). The main enteric pathogens were enteropathogen Escherichia coli (24/126), rotavirus (17/126) and Salmonella (16/126). A co-detection was found in 51.9% (40/77) of cases. Four patient profiles, considering the severity and the pathogen involved, were highlighted.

Abstract
Background Adolescent weight disorders ranging from anorexia nervosa (AN) to obesity (OB) can impact the heart by causing opposite alterations in its morphology, suggesting a direct impact of body mass index (BMI) on the heart. Cardiac function is relatively preserved as assessed by standard echocardiography. However, few studies have used 2D speckle-tracking echocardiography (2D-STE), which can detect subtle alterations of left ventricular (LV) function by evaluating deformations. This study aimed to assess the link between the BMI z-score of adolescent girls and myocardial function. Methods Ninety-one adolescent girls comprising 26 AN patients (age 14.6 ± 1.9 years), 28 OB patients (age 13.2 ± 1.4 years), and 37 controls (age 14.0 ± 2.0 years) underwent 2D-STE to assess LV morphology and myocardial global and regional deformations. Results The BMI z-score of our population ranged from -4.6 to 5.2. LV morphological remodeling was significantly and positively correlated with the BMI z-score (R2 = 0.456, p < 0.0001 for LV mass). Global longitudinal strain (LS) and regional LS recorded at the mid and apical levels were significantly correlated with the BMI z-score (R2 = 0.196, p = 0.0001 and R2 = 0.274, p < 0.0001, respectively, for apical and medial LS). Circumferential strains and twisting mechanics were not correlated with the BMI z-score. Fibrinogen and systolic blood pressure were the main variables explaining the alteration of LS. Conclusion We observed that the BMI z-score had an impact on LV mechanics, especially on medial and apical LS. Neither circumferential nor twisting mechanics were altered by the BMI z-score in adolescent girls.

Abstract
PURPOSE Childhood lymphoma survivors (CLSs) are at high risk of reduced daily activity. This work studied metabolic substrate use and cardiorespiratory function in response to exercise in CLSs. METHODS Twenty CLSs and 20 healthy adult controls matched for sex, age, and BMI took an incremental submaximal exercise test to determine fat/carbohydrate oxidation rates. Resting echocardiography and pulmonary functional tests were performed. Physical activity level, and blood metabolic and hormonal levels were measured. RESULTS CLSs reported more physical activity than controls (6317 ± 3815 vs. 4268 ± 4354 MET-minutes/week, p = 0.013), had higher resting heart rate (83 ± 14 vs. 71 ± 13 bpm, p = 0.006), and showed altered global longitudinal strain (- 17.5 ± 2.1 vs. - 19.8 ± 1.6%, p = 0.003). We observed no difference in maximal fat oxidation between the groups, but it was reached at lower relative exercise intensities in CLSs (Fatmax 17.4 ± 6.0 vs. 20.1 ± 4.1 mL/kg, p = 0.021). At V̇O2 peak, CLSs developed lower relative exercise power (3.2 ± 0.9 vs. 4.0 ± 0.7 W/kg, p = 0.012). CONCLUSION CLSs reported higher levels of physical activity but they attained maximal fat oxidation at lower relative oxygen uptake and applied lower relative power at V̇O2 peak. CLSs may thus have lower muscular efficiency, causing greater fatigability in response to exercise, possibly related to chemotherapy exposure during adolescence and childhood. Long-term follow-up is essential and regular physical activity needs to be sustained.

Abstract
Sleep is bi-directionally linked to energy balance. This crossover study design will evaluate the acute effect of a moderate energy deficit (500 kcal) induced by diet, exercise, or mixed (-250 kcal by diet and 250 kcal by exercise) on sleep and the next morning's appetitive responses. The study sample comprises 24 healthy young adults. The experimental measurements will be conducted in a naturalistic, momentary manner and partly assessed by the participants. The participants will undergo a run-in period in order to stabilize their sleep schedules and provide them with training on the study protocol and measurements. Indirect calorimetry will be used to determine their resting metabolic rate and peak oxygen consumption (VO2 peak). Then, they will take part in a control session (CTL), followed by three energy deficit sessions in random order: a diet-induced energy deficit session (DED), an exercise-induced energy deficit session (EED), and a mixed energy deficit session (MED). All experimental sessions will be separated by a one-week washout. The participants' sleep will be monitored by ambulatory polysomnography, and the next morning's appetitive response will be evaluated via ad libitum food intake, appetite sensations, and food reward, measured by a food liking and wanting computerized test.

Abstract
Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in young people. Although biologics now enable most children and adolescents with JIA to enjoy clinical remission, patients present lower physical activity and spend more time in sedentary behavior than their healthy counterparts. This impairment probably results from a physical deconditioning spiral initiated by joint pain, sustained by apprehension on the part of both the child and the child's parents, and entrenched by lowered physical capacities. This in turn may exacerbate disease activity and lead to unfavorable health outcomes including increased risks of metabolic and mental comorbidities. Over the past few decades, there has been growing interest in the health benefits of increased overall physical activity as well as exercise interventions in young people with JIA. However, we are still far from evidence-based physical activity and / or exercise prescription for this population. In this review, we give an overview of the available data supporting physical activity and / or exercise as a behavioral, non-pharmacological alternative to attenuate inflammation while also improving metabolism, disease symptoms, poor sleep, synchronization of circadian rhythms, mental health, and quality of life in JIA. Finally, we discuss clinical implications, identify gaps in knowledge, and outline a future research agenda.

Abstract
BACKGROUND Overcrowding of paediatric emergency departments (EDs) is a worldwide issue, where improving the quality of care is a priority. The main objective of this study was to determine the effect of triage nurse-initiated X-ray radiography on length of stay in paediatric emergency admissions. METHODS This retrospective, monocentric, descriptive study was performed in two successive 3-month periods: a pre-protocol ('before') period from 3 February to 3 May 2020 and a protocol ('after') period from 4 May to 2 August 2020, when patients underwent nurse-initiated X-ray radiography. The study involved all patients who were aged ≥3 years, valid, non-hyperalgic, accompanied by their parents and consulting at the paediatric ED for a simple closed distal trauma, involving a single limb segment or joint. RESULTS A total of 695 patients were included, 298 in the first period and 397 in the second period. The median length of stay in the paediatric ED was significantly shorter during the second period (119 min [80, 165] vs. 80 min [60, 105], P < 0.001), i.e. a median reduction time of 39 min or 33% (effect size = - 0.68, 95% confidence interval [-0.84 to -0.53]). Triage nurse requests were judged 'adequate and sufficient' in 95.2% of cases, with only 2.0% of instances deemed 'unnecessary' by the medical team. In 2.8% of cases, 'another X-ray' was required to support diagnosis. CONCLUSIONS The application of a triage nurse X-ray protocol significantly reduced the length of stay in a paediatric ED. The quality of patient management remained unchanged, and nurse requests were relevant.

Abstract
This study aimed to determine the short-term effect of two isocaloric diets differing in the ratio of protein−carbohydrate on melatonin levels, sleep, and subsequent dietary intake and physical activity in healthy young men. Twenty-four healthy men took part in a crossover design including two sessions of three days on isocaloric diets whether high-protein, low-carbohydrate (HPLC) or low-protein, high-carbohydrate (LPHC) followed by 24-h free living assessments. Sleep was measured by ambulatory polysomnography pre-post-intervention. Melatonin levels were assessed on the third night of each session on eight-point salivary sampling. Physical activity was monitored by accelerometry. On day 4, participants reported their 24-h ad-libitum dietary intake. LPHC resulted in better sleep quality and increased secretion of melatonin compared to HPLC. A significant difference was noted in sleep efficiency (p < 0.05) between the two sessions. This was mainly explained by a difference in sleep onset latency (p < 0.01) which was decreased during LPHC (PRE: 15.8 ± 7.8 min, POST: 11.4 ± 4.5 min, p < 0.001). Differences were also noted in sleep staging including time spent on REM (p < 0.05) and N1 (p < 0.05). More importantly, REM latency (PRE: 97.2 ± 19.9 min, POST 112.0 ± 20.7 min, p < 0.001) and cortical arousals (PRE: 7.2 ± 3.9 event/h, POST 8.5 ± 3.3 event/h) increased in response to HPLC diet but not LPHC. On day 4, 24-h ad-libitum energy intake was higher following HPLC compared to LPHC (+64 kcal, p < 0.05) and explained by increased snacking behavior (p < 0.01) especially from carbohydrates (p < 0.05). Increased carbohydrates intake was associated with increased cortical arousals.

Abstract
Cardiovascular alterations in anorexia nervosa (AN) adolescents include bradycardia and decreased systolic blood pressure and left ventricular mass. However, their determinants remain poorly understood. We assessed the associations between morphological and functional left ventricular (LV) remodeling, autonomic control by heart rate variability (HRV) analysis, thyroid hormones and brain natriuretic peptide (BNP) levels in AN female adolescents without or with weight recovery (WR). Fifty-nine female adolescents including 16 AN patients without WR (mean age 13.9 years (10−16)), 10 AN patients with WR (15.7 years (12−18)) and 33 controls (14.1 years (10−18)) underwent night heart rate (HR) recording to measure HRV (and especially SD1/SD2, the ratio between instantaneous (SD1) and long-term (SD2) standard deviation of R-R intervals, reflecting sympatho-vagal balance), speckle tracking echocardiography to assess LV global longitudinal strain (GLS) and blood test for dosage of tri-iodothyronine (T3) hormone and NT-proBNP. Compared to controls, AN patients without WR presented with lower HR (55 ± 7 vs. 68 ± 6 bpm; p < 0.001), parasympathetic hyperactivity, and higher GLS (−19.2 ± 1.8 vs. −16.9 ± 2.8%; p = 0.009). These alterations were partly abolished in AN patients with WR. In a multivariate regression analysis, T3 was the main factor explaining the variance of SD1/SD2, a sympatho-vagal balance marker. NT-proBNP levels were not correlated with cardiac alterations. AN patients had parasympathetic hyperactivity linked with their rate of T3, and a higher GLS. These alterations were partly restored in AN patients with WR.

Abstract
Background Anorexia nervosa (AN) is accompanied by bradycardia, low blood pressure (BP) and cardiac morphological remodeling. Systolic and diastolic functions are relatively preserved when assessed by standard ultrasound methods. However, novel advances based on speckle tracking echocardiography (STE), that could detect subtle and early alterations of left ventricular (LV) function, remained poorly used in AN patients. Objective The aim of this study was to assess the cardiac function of AN patients by evaluating LV myocardial strains, myocardial work (MW) and LV mechanical dispersion. We hypothesized that LV strains and global myocardial work would be decreased and LV twisting mechanisms enhanced to preserve the systolic function. Methods Fifty-nine adolescents including 26 women AN patients (14.6 ± 1.9 yrs. old) with a mean duration of AN of 19 ± 9 months and 33 controls (14.1 ± 2.0 yrs. old) underwent STE to assess LV morphology and myocardial regional strains. Results The global longitudinal strain (GLS) was higher in AN patients compared to controls (−18.8 ± 2.0 vs. −16.9 ± 2.8%, p = 0.006). The area under the pressure-strain loop, representing the global MW was not altered but was shifted to the left and downwards in AN patients, due to their lower BP and higher GLS. Intraventricular mechanical dispersion was similar in both groups. Circumferential strains, twisting/untwisting mechanics were preserved. Conclusion Our results strongly support that the cardiac morphological remodeling observed in our AN patients was associated with normal ventricular regional myocardial functions. Only GLS was higher in AN patients, but its clinical significance remains to be demonstrated.

Abstract
Codeine use was restricted in 2013 and is currently contraindicated for children below the age of 12 years. We examined how the prescription of opioid analgesics in children in France evolved between 2012 and 2018. Our population-based study from the SNIIRAM database (National System of Health Insurance Inter-Regime Information) was designed to determine trends in opioid prescription from 2012 to 2018 in all French children. The number of children who received at least one opioid prescription gradually declined from 452,665 in 2012 (347.5 children per 10,000) to 169,338 in 2018 (130.3 children per 10,000). This decrease was especially marked for codeine (36 children per 10,000 in 2018 vs. 308.5 children per 10,000 in 2012), whereas the number of tramadol prescriptions increased by 171% in 2018 (94.6 children per 10,000). Despite the increase, strong opioids still formed only a small proportion of prescriptions (2.6 children per 10,000 given opioids in 2018). Overall opioid prescriptions in French children dramatically decreased between 2012 and 2018, probably owing to restrictions on the use of codeine. Codeine has been partly replaced by tramadol. Morphine is still probably underused. This suggests that opioids are being used less often for pain management in children.

Abstract
BACKGROUND Neonatal bacterial infections must be bacteriologically confirmed from laboratory samples to best adjust antibiotic therapy. Lumbar puncture (LP) has been recommended for infants younger than 1 month with suspected serious bacterial infection (SBI) to manage possible meningitis. However, the incidence of bacterial meningitis associated with other infections and particularly with urinary tract infections (UTIs) is low. Recourse to systematic LP may be less essential if infants have a UTI. We aimed (a) to determine the management and frequency of bacterial meningitis coexisting with a documented diagnosis of UTI in infants aged < 1 month who had an LP, and (b) to evaluate the management of infants in emergency admissions with suspected SBI while assessing antibiotic treatment. METHODS We conducted a retrospective single-center study from January 2010 to April 2019 including all cases of neonatal bacterial infections, and collected data on the clinical, laboratory, and radiological features. RESULTS In all, 409 infants were included in the study. Of these, 162 (39.6%) presented with a UTI and eight (2%) had bacterial meningitis. Of the infants diagnosed with UTI, 74.7% had an LP, of whom 34.7% experienced LP complications. No coexistence of UTI and bacterial meningitis was found among infants who had an LP and a documented UTI. CONCLUSION Although not all infants had an LP and a urine culture at the same time, these results show that bacterial meningitis coexisting with a confirmed UTI diagnosis in infants is rare. Furthermore, LP can be traumatic in some cases and therefore its utility should be assessed according to the clinical context.

Abstract
Background: Anorexia nervosa (AN) and obesity (OB) lead to changes in SBP (i.e., loading conditions) that may affect left ventricular (LV) myocardial work (MW). The novel concept of LV pressure-strain loops allows non-invasive estimation of MW, this latter being correlated with cardiac energy metabolism. In addition, the study of regional MW can detect subtle alterations in cardiac function by highlighting an abnormal distribution of MW. Objective: The aim of this study was to assess the cardiac function of AN and OB patients by evaluating global and regional LV strains and MW. Methods: Eighty-seven female adolescents, comprising 26 with AN (14.6 ± 1.9 yrs. old), 28 with OB (13.2 ± 1.4 yrs. old), and 33 controls (14.0 ± 2.0 yrs. old) underwent speckle-tracking echography to assess global and regional LV strains and MW. Results: SBP was higher in adolescents with obesity than in AN patients or controls. Global MW was similar between groups. In AN patients and controls, longitudinal strains were higher at the apex than at the base of the LV, whereas they were similar in obesity patients, owing to a decrease in their apical longitudinal strain. Consequently, their MW was higher at the basal level than either of the other two groups (1854 ± 272 vs. 1501 ± 280 vs. 1575 ± 295 mmHg% in OB patients, AN patients, and controls, respectively. Conclusion: Despite altered SBP, the global MW of adolescents with weight disorders was unaffected. However, in adolescents with obesity, the distribution of their regional LV MW was altered, which might reflect specific regional remodeling.

Abstract
Background: A better understanding of the influence of energy balance on sleep in adolescents, particularly those with obesity, could help develop strategies to optimize sleep in these populations. The purpose of this study was to investigate sleep under ad libitum-vs-controlled diets adjusted to energy requirement (eucaloric) among adolescents with obesity and their normal weight controls. Methods: Twenty-eight male adolescents aged between 12 and 15 years, n = 14 adolescents with obesity (OB: BMI ≥ 90th centile) and n = 14 normal weight age matched controls (NW), completed an experimental protocol comprising ad libitum or eucaloric meals for three days, in random order. During the third night of each condition, they underwent in home polysomnography (PSG). Results: An interaction effect of energy intake (EI) was detected (p < 0.001). EI was higher during ad libitum compared to the eucaloric condition (p < 0.001) and in OB compared to NW (p < 0.001) in the absence of any substantial modification to macronutrient proportions. Analyses of energy intake distribution throughout the day showed a significant interaction with both a condition and group effect during lunch and dinner. Sleep improvements were noted in OB group during the eucaloric condition compared to ad libitum with reduced sleep onset latency and N1 stage. Sleep improvements were correlated to reduced EI, especially during the evening meal. Conclusion: Simply adjusting dietary intake to energy requirement and reducing the energy proportion of the evening meal could have therapeutic effects on sleep in adolescents with obesity. However, positive energy balance alone cannot justify worsened sleep among adolescents with obesity compared to normal weight counterparts.

Abstract
STUDY OBJECTIVES Juvenile idiopathic arthritis (JIA) is one of the most common pediatric rheumatic disease. However, sleep alteration associated with this auto-immune disease remain unclear. We aimed in this systematic review and meta-analysis to compare sleep duration, quality, and architecture in JIA subjects with those in their healthy peers. METHODS Systematic search performed in PubMed, EMBase, Cochrane, and PsycINFO databases included 19 studies in the qualitative synthesis of which 10 met the inclusion criteria for the meta-analysis. RESULTS Pooled results from subjective methods indicated pronounced sleep disturbances and complaints in youth with JIA compared with their healthy counterparts. This was further confirmed by Increased difficulty maintaining sleep (wake after sleep onset; SMD: -0.69; CI: -1.29; -0.09, p =0.02) and a tendency to increased difficulty initiating sleep (sleep onset latency; SMD: -0.29; CI: -0.60; 0.03, p =0.07). There were no remarkable differences in sleep duration or sleep architecture between JIA patients and healthy controls. High heterogeneity was found for several outcomes. This could be explained by the different methods used as well as associated sleep disorders, medication and comorbidities. CONCLUSIONS Although included studies were methodologically diverse, the summarized results of our review and meta-analysis bring evidence that children with JIA present more fragmented sleep compared to healthy peers. Thereby, the implementation of strategies to manage and improve sleep in this population are needed and might have a beneficial effect on the symptoms and functions of JIA.

Abstract
AIM AND OBJECTIVE The objective of this study was to evaluate the AccuVeinAV400® viewing device for peripheral venous catheter insertion in children on the first try. BACKGROUND Inserting a peripheral venous catheter is the most frequent invasive procedure carried out by healthcare professionals in hospitalised children. Several attempts are sometimes necessary, and veins can be damaged. DESIGN A quasi-experimental cluster randomised controlled trial based on the CONSORT 2010 guidelines. METHODS This randomised study comparing standard practice to the use of AccuVein400® was carried out on children who were less than 3 years old, with difficult intravenous access (DIVA Score), hospitalised in three paediatric units and who needed cannulation. RESULT A total of 304 children were included (156 in the AccuVein arm and 148 in the standard arm). There was no significant difference between AccuVein and standard groups in age (respectively, 2.5 ± 0.9 years vs. 2.5 ± 0.8), or mean DIVA score (respectively 5.9 ± 1.3 vs. 5.5 ± 1.2). The success of cannulation on the first attempt was 40.38% in the AccuVein arm vs. 41.2% in the standard arm (p = .6). The caregiver's assessment of pain on the Face Legs Activity Cry Consolability scale was 4.8 ± 0.2 in the AccuVein arm vs. 5.0 ± 0.2 (p = .4). CONCLUSIONS The use of AccuVein400® did not lead to greater success in intravenous insertion at the first attempt in children under 3 years of age with difficult intravenous access. RELEVANCE TO CLINICAL PRACTICE This device can therefore be used according to the healthcare professionals' situation and needs. It is widely used in paediatric wards, and our study shows that it offers a support tool that reassures healthcare professionals and helps validate their choice of vein easiest to catheterise.

Abstract
Objective: We evaluated substrate utilization during submaximal exercise, together with glycemic responses and hormonal counter-regulation to exercise, in children with type 1 diabetes mellitus (T1DM). Methods: Twelve pre-pubescent children with T1DM and 12 healthy children were matched by sex and age. Participants completed a submaximal incremental exercise test to determine their fat and carbohydrate oxidation rates by indirect calorimetry. Levels of glycemia, glucagon, cortisol, growth hormone, noradrenaline, adrenaline, and insulin were monitored until 120 min post-exercise. Results: Absolute peak oxygen uptake (VO2 peak) was significantly lower in the children with T1DM than in the healthy controls (1131.4 ± 102.5 vs. 1383.0 ± 316.6 ml.min−1, p = 0.03). Overall carbohydrate and lipid oxidation rates were the same in the two groups, but for exercise intensities, higher than 50% of VO2 peak, fat oxidation rate was significantly lower in the children with T1DM. The absolute maximal lipid oxidation rate was significantly lower in the T1DM children (158.1 ± 31.6 vs. 205.4 ± 42.1 mg.min−1, p = 0.005), and they reached a significantly lower exercise power than the healthy controls (26.4 ± 1.2 vs. 35.4 ± 3.3 W, p = 0.03). Blood glucose responses to exercise were negatively correlated with pre-exercise blood glucose concentrations (r = −0.67; p = 0.03). Conclusion: Metabolic and hormonal responses during sub-maximal exercise are impaired in young children with T1DM.

Abstract
Young athletes must contend with the constraints of elite sports on top of school commitments and the physiological processes associated with adolescence. This study assessed week and weekend sleep and schedule of activities in elite adolescent rugby players during the in-season competitive phase compared with age-matched non-athlete controls. 32 adolescents (GR: 16 elite rugby players, GC: 16 controls) from the same boarding school filled out a daily schedule of activities and a sleep diary, and wore a multichannel electroencephalogram for 14 days. They later filled out questionnaires on their sleep quality, sleepiness, and perceived stress. Both groups showed insufficient sleep duration during the week (<7 h). Only GC caught up on their sleep debt during the weekend (increased TIB, TST and time spent in REM sleep, all p < 0.001). Weekend TIB, TST and, N3 sleep remained similar to that for weekdays in GR. However, GR experienced lower sleep quality (decreased SE, increased WASO, all p < 0.01) and a decrease in REM sleep (p < 0.01). Schedules of activities showed an increase in time spent on overall activities during the weekend, mainly due to competition and sport-specific travel, which resulted in a decrease in sleep opportunity time compared with GC (p < 0.001). Δ sleep opportunity time (weekend-week) was associated with Δ TST (weekend-week), and Δ TST (weekend-week) was associated with sleepiness and perceived stress. Busy schedules during the competitive season decreased sleep opportunity time and prevented elite adolescent rugby players from catching up on their sleep at weekends.HIGHLIGHTS Adolescent rugby players have insufficient sleep during both week and weekend of the in-season competitive phaseCongested schedule prevented elite adolescent rugby players from catching up on their sleep at weekends.Sleep considerations are necessary when planning the weekend sporting schedules.

Abstract
INTRODUCTION The purpose of this study was to assess differences in observed pain-related behaviors during cannulation between a device combining cold and vibration (Buzzy) and the standard care (EMLA patch). METHODS Patients 18 months to 6 years old, requiring venous access in a pediatric emergency department, received either the Buzzy device or the EMLA patch. Predefined week randomization ensured equal allocation to the 2 intervention groups. Pain during cannulation was measured using the Children's Hospital of Eastern Ontario Pain Scale. Parent and nurse reports, cannulation success, and venous access times were also assessed. RESULTS In total, 607 included patients were randomized into the Buzzy group (n = 302) or the EMLA group (n = 305). Observed pain-related behaviors scores, parent-assessed pain scores, and nurse-reported pain ratings were higher with Buzzy. CONCLUSIONS Pain relief by a combination of cold and vibration during cannulation is not as effective as the standard-care method in children 18 months to 6 years old.

Abstract
AIM To assess muscle function and functional abilities in children with juvenile idiopathic arthritis (JIA). METHODS Fourteen children with JIA and 14 healthy controls matched for age and sex were included. Muscle characteristics, both structural (thickness, cross-sectional area (CSA) and fascicle angle) and qualitative (intermuscular adipose tissue; IMAT), were assessed in thigh muscles using ultrasound and peripheral quantitative computed tomography (pQCT). Muscle function and functional abilities were determined from the assessment of maximal voluntary isometric contraction (MVIC) knee extensors force and vertical jump performance. RESULTS No significant difference in MVIC force was observed between the two groups. However, squat jump height was significantly reduced in children with JIA (18.3 ± 5.4 vs 24.3 ± 7.9 cm, P < .05). No differences in structural parameters were observed, but IMAT/CSA (0.22 ± 0.02 vs 0.25 ± 0.03; P = .01) was significantly lower in children with JIA than in healthy children. CONCLUSION Knee extensor muscle architecture and force were comparable between children with and without JIA, but functional abilities (vertical jump performance) were poorer in JIA. The lower IMAT area in JIA could result from a lower physical activity level compared with healthy children.

Abstract
Hematopoietic progenitor cells-apheresis (HPC-A) collection is now a routine procedure for autologous hematopoietic stem cell transplantation. Here we present our 25 years' experience of HPC-A collection in children weighing 8 kg or less, with a focus on the evolution of our standard operating procedures, and the safety limits for these young patients, in the Pediatric Apheresis Unit of Clermont-Ferrand University Hospital (France). Fifteen children weighing 8 kg or less underwent 26 HPC-A collections over 25 years. Median CD34+ cell yield by leukapheresis was 4.4 106 /kg. No procedure-related complications were encountered during or after the collection. No patient had profound thrombocytopenia or anemia that needed post-collection transfusions. Our experience in pediatric oncology patients who underwent HPC-A collections shows that this procedure can be performed even in the smallest of children with no increase in toxicity provided all precautions are taken to ensure that the procedure is carried out under the ideal conditions.

Abstract
Disturbed sleep is common in adolescents. Ingested nutrients help regulate the internal clock and influence sleep quality. The purpose of this clinical trial is to assess the effect of protein tryptophan (Trp)/large neutral amino acids (LNAAs) ratio on sleep and circadian rhythm. Ingested Trp is involved in the regulation of the sleep/wake cycle and improvement of sleep quality. Since Trp transport through the blood-brain barrier is competing with LNAAs, protein with higher Trp/LNAAs were expected to increase sleep efficiency. This randomized double-blind controlled trial will enroll two samples of male adolescents predisposed to sleep disturbances: elite rugby players (n = 24) and youths with obesity (n = 24). They will take part randomly in three sessions each held over a week. They will undergo a washout period, when dietary intake will be calibrated (three days), followed by an intervention period (three days), when their diet will be supplemented with three proteins with different Trp/LNAAs ratios. Physical, cognitive, dietary intake, appetite, and sleepiness evaluations will be made on the last day of each session. The primary outcome is sleep efficiency measured through in-home electroencephalogram recordings. Secondary outcomes include sleep staging, circadian phase, and sleep-, food intake-, metabolism-, and inflammation-related biochemical markers. A fuller understanding of the effect of protein Trp/LNAAs ratio on sleep could help in developing nutritional strategies addressing sleep disturbances.

Abstract
BACKGROUND Although adolescence and obesity are related to impaired sleep duration and quality, exercise was admitted as a nonpharmacological treatment for sleep and better control of energy balance. OBJECTIVES To investigate the acute effects of intense exercise on sleep and subsequent dietary intake. METHODS Sixteen adolescent girls with obesity (age 13.7 ± 1.1 years, weight 82.7 ± 10.2 kg, body mass index (BMI) 30.5 ± 3.4 kg/m2 , fat mass (FM) 39.2 ± 3.1%, Pittsburgh Sleep Quality Index (PSQI) 8.6 ± 2.8, paediatric daytime sleepiness scale (PDSS) 19.6 ± 5.9) took part in two experimental sessions in a random order: Control (CTL) and Exercise (EX). The two sessions were identical except for a continuous ergocycle exercise bout lasting 40 minutes and performed at 70% VO2max at the end of the morning of EX. Energy expenditure and sleep were measured by accelerometry and next-morning dietary intake in an ad libitum meal. RESULTS Higher sleep duration (P < 0.03) and quality (decreased WASO: P < 0.02; increased SE%: P < 0.02) were observed in EX compared with CTL. This was associated with a nonsignificant decrease in caloric intake (-78 kcal) and a significant decrease in food energy density (P < 0.04), fat, and sugar consumption (respectively, P < 0.02 and P < 0.05) the following morning. CONCLUSIONS Acute exercise efficaciously increased sleep duration and quality, resulting in a decrease in subsequent energy-dense food consumption in adolescent girls with obesity.

Abstract
Background: Leukemia is the most common cancer in pediatrics, with many late effects such as higher risk of dyslipidemia, insulin resistance, obesity, and metabolic syndrome. The objective of this work was to investigate substrate oxidation during submaximal exercise in survivors of childhood acute leukemia. Methods: A total of 20 leukemia survivors and 20 healthy children were matched by sex, age, and Tanner stage. They all took a submaximal incremental exercise test to determine fat and carbohydrate oxidation rates. Results: Cardiorespiratory fitness was significantly lower in leukemia survivors, with lower relative VO2 peaks (p < 0.001), lower heart rate values (p = 0.02), and lower exercise power (p = 0.012), whereas rest metabolism and body mass index did not differ between the two groups. During exercise, upward of heart rate relative to VO2 peak was significantly higher (p < 0.001) in childhood leukemia survivors. We found lower carbohydrate and fat oxidation rates (p = 0.07) in leukemia survivors compared with healthy children, and also a significantly lower relative maximal fat oxidation rate (p = 0.014). Conclusion: Despite impaired physical fitness and metabolic response to exercise, childhood leukemia survivors remained sensitive to physical activity interventions, and could readily adapt to submaximal exercise intensity.

Abstract
Acute bronchiolitis is responsible for high morbidity in infants. Club cell protein 16 kDa (CC16) is a major pneumoprotein secreted by club cells of the bronchial epithelium and eliminated by the renal pathway. CC16 seems to be a biomarker of epithelial damage in asthma. However, its value as a marker of acute bronchiolitis severity and later recurrent wheezing are uncertain, especially the value of its urinary assay for this purpose. A prospective, observational, analytical study was conducted at Clermont-Ferrand University Hospital to correlate serum CC16 level with clinical severity of bronchiolitis in hospitalized infants aged less than 1 year. We analyzed correlations between serum and urinary CC16, CC16 levels and Wainwright score, immediate morbidity due to bronchiolitis, causal viruses, and recurrent wheezing 1 year after inclusion. In 166 infants, serum CC16 did not correlate with acute bronchiolitis severity (P = .49), but urinary CC16 did (P < .001). In multivariate analysis, urinary CC16 correlated mainly with urinary retinol binding protein (RBP; r = 0.70; P < .001). The logCC16u/logRBPu ratio correlated significantly with severity (P = .02). CC16 levels were not correlated with recurrent wheezing at 1 year. Urinary CC16 could be a useful biomarker in acute bronchiolitis for specific indications. This noninvasive assay would be particularly useful in the young infant population. Several factors must be taken into account in its interpretation, mainly tubular function. Further studies are needed to assess these factors.

Abstract
BACKGROUND/OBJECTIVES Survival rates in children diagnosed with malignant brain tumors exceed 70%. A higher risk of dyslipidemia, central obesity, and insulin resistance has been reported among these children. We investigated substrate utilization during submaximal exercise. DESIGN/METHODS Ten brain tumor survivors and 10 healthy children were matched by sex, age, and Tanner stage. Participants completed a submaximal incremental exercise test to determine their fat and carbohydrate oxidation rates. RESULTS The relative oxygen volume (VO2 ) peak was significantly higher in the control group than in the survivors of childhood brain tumors (43.3 ± 11.9 and 32.4 ± 10.2 mL/kg /min, P = .04). At the same relative exercise intensity, there was no difference in the carbohydrate or lipid oxidation rate between the two groups, or in the maximal fat oxidation (MFO) rate, or in the heart rate or percentage of VO2 peak to reach MFO. Healthy children achieved MFO at significantly higher muscular power than did brain tumor survivors (47.9 ± 20.8 and 21.8 ± 9.6 W, P = .003). CONCLUSION Because child brain tumor survivors are less physically fit than healthy children, and substrate utilization during submaximal exercise is not different, physical activity should be promoted for child brain tumor survivors.

Abstract
BACKGROUND Physical activity (PA) is essential for children throughout their growth and maturation. It improves physiological and psychological health and limits the risk of developing metabolic disorders. However, some chronic physiological and metabolic diseases may lead to decreased PA. The diversity of outcomes in the literature offers no consensus for physical activity and sedentary levels in children with juvenile idiopathic arthritis (JIA) or inflammatory bowel disease (IBD). METHODS A literature review and a meta-analysis were carried out with original studies from a Medline database search. Only high-quality studies (STROBE checklist) written in English comparing PA level or sedentary behavior (SB) between children with the disorders and their healthy peers were considered. The aim was to examine PA and SB in children with JIA or IBD compared to their healthy peers. RESULTS The literature review and meta-analysis identified decreased PA and increased time spent in SB in these populations, which may exacerbate both their lower physical fitness and the symptoms of their health disorders. CONCLUSION Results nevertheless show discrepancies due to the different materials and methods used and the variables measured. Further studies are needed to establish a gold standard method for assessing PA level in these populations.

Abstract
BACKGROUND Children with juvenile idiopathic arthritis (JIA) have impaired physical abilities. TNF-α plays a crucial role in this pathogenesis, but it is also involved in the use of lipids and muscle health. Objective of this study was to explore substrate oxidation and impact of TNF blockade on energy metabolism in children with JIA as compared to healthy children. METHODS Fifteen non-TNF-blockaded and 15 TNF-blockaded children with JIA and 15 healthy controls were matched by sex, age, and Tanner stage. Participants completed a submaximal incremental exercise test on ergocycle to determine fat and carbohydrate oxidation rates by indirect calorimetry. RESULTS The maximal fat oxidation rate during exercise was lower in JIA children untreated by TNF blockade (134.3 ± 45.2 mg.min- 1) when compared to the controls (225.3 ± 92.9 mg.min- 1, p = 0.007); but was higher in JIA children under TNF blockade (163.2 ± 59.0 mg.min- 1, p = 0.31) when compared to JIA children untreated by TNF blockade. At the same relative exercise intensities, there was no difference in carbohydrate oxidation rate between three groups. CONCLUSIONS Lipid metabolism during exercise was found to be impaired in children with JIA. However, TNF treatment seems to improve the fat oxidation rate in this population.

Abstract
Objectives: The objective of this study was to evaluate muscular metabolic function in children with inactive juvenile idiopathic arthritis (JIA). Methods: Fifteen children with inactive JIA and fifteen healthy controls were matched by sex, biological age, and Tanner stage. Participants completed a submaximal incremental exercise test to determine their fat and carbohydrate oxidation rates. Results: Between the two groups, heart rate values and carbohydrate oxidation rates were the same, regardless of the relative intensity of exercise. Lipid oxidation rates were lower in JIA patients, regardless of the percentage of VO2 peak (p < 0.05). Respiratory exchange ratios beyond 50% of VO2 peak were higher in patients with JIA (p < 0.05). Respective maximal fat oxidation rates (MFO) for controls and children with JIA were 218.7 ± 92.2 vs. 157.5 ± 65.9 mg ⋅ min-1 (p = 0.03) and 4.9 ± 1.9 vs. 3.4 ± 1.2 mg ⋅ min-1 ⋅ kg-1 (p = 0.04). There was no difference between the two groups in heart rate, percentage of VO2 peak, or power of exercise to achieve MFO. Controls reached their MFO at an exercise power significantly higher than did JIA subjects (42.8 ± 16.8 and 31.9 ± 9.8 W, p = 0.004). Conclusion: Children with JIA show metabolic disturbance during exercise, even when the disease is considered inactive. This disturbance is seen in a lower lipid oxidation rate during submaximal exercise.

Abstract
INTRODUCTION Acute bronchiolitis is a major cause of acute respiratory distress in infants. The soluble receptor for advanced glycation end-products (sRAGE) is a biomarker of pulmonary damage processes, with a diagnostic and a prognostic value in acute respiratory distress syndrome (ARDS). The RAGE pathway is also implicated in the pathogenesis of other respiratory diseases like asthma, but the value of sRAGE levels in acute bronchiolitis remains under-investigated. MATERIAL AND METHODS A prospective, observational, and analytical study was conducted at Clermont-Ferrand University Hospital. The main objective was to evaluate the correlation between serum sRAGE and clinical severity of bronchiolitis in hospitalized infants aged <1 year. We analyzed correlations between serum sRAGE and Wainwright score, short-term morbidity attributable to bronchiolitis, causal viruses and risk for recurrent wheezing at 1 year. RESULTS The study included 93 infants. sRAGE levels were significantly lower in acute bronchiolitis patients (mean 1101 pg/mL) than in controls (2203 pg/mL, P < 0.001) but did not correlate with clinical severity. No correlation was found between serum sRAGE and severity score, respiratory viruses, and recurrent wheezing at 1 year. Serum sRAGE levels were negatively correlated with age (r = -0.45, P < 0.001). CONCLUSION Serum sRAGE levels are decreased in acute bronchiolitis but not correlated with disease severity. sRAGE levels should be age-adjusted in infants. Serum sRAGE levels measured in the setting of acute bronchiolitis were not predictive of recurrent wheezing.

Abstract
The aim of this study was to measure the impact, at 24 h post-exercise, of a single exercise bout on plasma inflammatory markers such as calprotectin, IL-6, sIL-6 R, sgp130 and the hypothalamic-pituitary-adrenal (HPA) axis in children with juvenile idiopathic arthritis (JIA).Twelve children with JIA attended the laboratory on three consecutive days (control day, exercise day and 24 h post-exercise), including a 20-min exercise bout on a cycle-ergometer at 70% of max. HR at 8:30 a.m. on day 2. Plasma concentrations of calprotectin, IL-6, sIL-6 R, sgp130, cortisol, ACTH and DHEA were measured on venous blood samples taken every day.at rest and at 8:30, 8:50, 9:30, 10:30 a.m. and 12:00, 3:00, 5:30 p.m.A single exercise bout increased plasma calprotectin 1.7-fold (p<0.001) but did not increase IL-6 and soluble IL-6 receptors in short-term post-exercise recovery. However, at 24 h post-exercise, calprotectin, IL-6 and its receptors had decreased compared to control-day levels. There was a transient 2-fold increase in post-exercise self-evaluated pain (p=0.03) that disappeared in the evening without repercussions the following day.Physical activity in children with JIA results in a slight transient systemic inflammation but seems to be followed by counter-regulation at 24 h post-exercise with a decrease in proinflammatory markers.

Abstract
BACKGROUND Oral immunotherapy to peanut is effective in desensitizing patients but has significant side effects including anaphylaxis and gastrointestinal symptoms. In most protocols, peanut is administered in a vehicle food. OBJECTIVE In an exclusively adolescent population, we tested a new approach using sealed capsules of peanut (gastrointestinal delivery oral immunotherapy or GIDOIT) to bypass the upper gastrointestinal tract. The primary aim was to assess the efficacy of the oral build-up phase of GIDOIT and the secondary aim to analyse its safety. METHODS Adolescents with a history of a clinical allergic reaction after peanut ingestion were included in a 2-armed, parallel-design, individually randomized, double-blind, placebo-controlled, multicentre trial after a positive double-blind placebo-controlled oral food challenge (DBPCFC1). A central randomization centre used computer-generated tables to allocate treatments. Peanut (or placebo) capsules were ingested daily over a period of 24 weeks with increments every 2 weeks from 2 to 400 mg of peanut protein (pp). Primary outcome was tolerance of 400 mg of pp at DBPCFC2. RESULTS Thirty patients were included between September 2013 and May 2014. At DBPCFC2, unresponsiveness to 400 mg of pp was achieved in 17/21 peanut group patients (2 withdrawn patients) and 1/9 in the placebo group (Intention-to-treat analysis, P < .001, absolute difference = 0.7, 95%IC 0.43 0.96). Oropharyngeal symptoms were equally frequent in both groups. No dysphagia or other signs of eosinophilic oesophagitis occurred. Digestive adverse events (AE) were more frequent in the treated group (P = .02), but mild and without compliance issues. Only one severe advent event led to withdrawal in a patient who ingested twice the investigated treatment. Peanut-specific humoral immune responses were modulated. CONCLUSION The GIDOIT protocol demonstrated clinical and immunological efficacy and had an acceptable level of safety with weak oropharyngeal symptoms, no dysphagia, mild digestive events and few severe systemic AE.

Abstract
To assess risk factors of recurrent bronchial obstruction and allergic sensitization 3 years after an episode of acute bronchiolitis, whether after ambulatory care treatment or hospitalization. A monocentric prospective longitudinal study including infants aged under 1 year with acute bronchiolitis was performed, with clinical (severity score), biological (serum Krebs von den Lungen 6 antigen), and viral (14 virus by naso-pharyngeal suction detection) assessments. Follow-up included a quaterly telephone interview, and a final clinical examination at 3 years. Biological markers of atopy were also measured in peripheral blood, including specific IgEs towards aero- and food allergens. Complete data were available for 154 children. 46.8% of them had recurrent wheezing (RW). No difference was found according to initial severity, care at home or in the hospital, respiratory virus involved, or existence of co-infection. A familial history of atopy was identified as a risk factor for recurrent bronchial obstruction (60% for RW infants versus 39%, P = 0.02), as living in an apartment (35% versus 15%, P = 0.002). 18.6% of the infants were sensitized, with 48.1% of them sensitized to aeroallergens and 81.5% to food allergens. Multivariate analysis confirmed that a familial history of atopy (P = 0.02) and initial co-infection RSV-hRV (P = 0.02) were correlated with the risk of sensitization to aeroallergens at 3 years. Familial history of atopy and RSV-hRV co-infection are risk factors for recurrent bronchial obstruction and sensitization.

Abstract
BACKGROUND Juvenile Idiopathic Arthritis is the most common chronic pediatric rheumatic disease. The announcement of Juvenile Idiopathic Arthritis poses for parents a number of challenges that make it hard to accept a diagnosis of the disease for their child; yet to our knowledge, no study to date has focused on the time period immediately surrounding the diagnosis. This study sets out to describe parents' experiences in engaging with their child's diagnosis of Juvenile Idiopathic Arthritis. METHODS This is a mixed methods study. Semi-structured interviews of families with a Juvenile Idiopathic Arthritis child were conducted. A grounded-theory thematic analysis was performed. Items that emerged in the interviews were compiled into a self-administered questionnaire. RESULTS Eleven families participated in the qualitative study. Sixty families responded to the questionnaire. The path of parents was characterized by doubt (before, during and after diagnosis) while the disease tended to take center stage. Doubt was generated through mismatches in perspectives between the parents' circle of acquaintances, physicians, and the parents' own subjective experiences of symptoms. This study also found that social support and parent associations occupied an ambiguous position between help and stigmatization. CONCLUSIONS Doubt fuels self-energizing spirals that take root as parents learn the news that their child has Juvenile Idiopathic Arthritis. These spirals of doubt may influence parents' experiences at every stage throughout the course of disease. Our data support the implementation of a specific process dedicated to breaking the news of Juvenile Idiopathic Arthritis to parents.

Abstract
INTRODUCTION Central nervous system tumors (CNST) are the most lethal of solid tumors in childhood cancer. PATIENTS AND METHODS We report incidence and survival data for all CNST (International Classification of Diseases for Oncology third edition, category III or Xa) recorded in children under 15 years of age by the Auvergne-Limousin cancer registry for the period 1986-2009. RESULTS Annual incidence of all CNST was 3.27 per 100,000 and the male to female ratio was 0.95. Over 45.0% of CNST were glial. Astrocytomas (36.2%) showed the highest incidence for each age group except between 1 and 4 years where embryonal tumors were more common. For all CNST, no significant variation in incidence over time was observed for the evaluated period of 23 years (annual percent change: -0.4%, 95% CI, [-2.8-2.1]). Globally, 5 years overall survival was 67% [59-73] and had increased by more than 16% between 1986-1999 and 2000-2009, mainly due to better survival for astrocytomas, other gliomas, ependymomas and choroid plexus tumors (P=0.01). CONCLUSION We report that the incidence of CNST in Auvergne-Limousin is similar to that in the literature and did not increase between 1986 and 2009. In addition, 5 years overall survival increased after 1999, especially for surgically treatable tumors.

Abstract
Background Peanut allergy is an increasingly common health problem. Current treatment guidelines are based on strict avoidance. However, in the last few years, oral immunotherapy protocols have shown promising results yielding increased tolerance to peanut in allergic children. Adolescence is particularly at risk. Methods/Design We have designed a randomized, double-blind, placebo-controlled, multicenter study to investigate the efficacy and safety of peanut oral escalating immunotherapy in a 12- to 18–year-old population with proved allergy to peanut. Patients are selected when the threshold of peanut intake is over 100 mg and 2 cumulated g on the first double-blind, placebo-controlled oral food challenge (DBPCOFC). During the build-up placebo-controlled blinded phase, doses containing peanut or placebo will be administered by gradual up-dosing from 10 mg to 2 g with 2-weekly increments. After this first randomized phase, the desensitized participants will continue to intake native peanut in an unblinded process during 13 or 37 weeks following a second randomization. Adverse events are picked up and managed throughout the entire protocol. The main endpoint is the percentage of patients with negative DBPCOFC at the threshold of 2 g of cumulative peanut at the end of the build-up phase of 24 weeks. Secondary endpoints include: (1) desensitization 6 weeks and 6 months after the end of the maintenance phase; (2) adverse effects during the build-up phase; (3) immunological profile confirming peanut desensitization. Immunologic assays will be carried out at every DBPCOFC and at the middle of the build-up phase to evaluate the peanut immunologic profile modifications. Discussion This double-blind, placebo-controlled study will be, to our knowledge, the first evaluation of a peanut oral immunotherapy protocol in teenagers in the purpose to reduce severe reactions after unexpected intake and to improve quality of life. Trial registration ClinicalTrial.gov: NCT02046083 (23 January 2014).

Abstract
Clinical grading of GI involvement during acute GVHD remains a challenging issue, especially in children. Plasma citrulline, a non-protein amino acid selectively produced and released by enterocytes, is a suitable surrogate endpoint for small intestinal epithelial cell mass, irrespective of the underlying cause of cell loss. Children referred for allogeneic bone marrow transplantation who were free from chronic malabsorption or constitutional disease involving the GI tract were consecutively included in this prospective study. Plasma citrulline and albumin concentration was measured every week between day 7 and day 28 of BMT until resolution of the aGVHD or occurrence of chronic GVHD. In total, 31 children were included between 2008 and 2011. After a CR, citrulline levels fell to a minimum level on day 7 and then increased to reach the initial value on day 28. After day 28, plasma citrulline but not albumin was strongly linked to the occurrence of GI GVHD, the threshold being set at 10 μmol/L. The correlation with clinical grade of GI-aGVHD now needs to be assessed in larger populations. In pediatric patients, citrulline is valuable as a suitable non-invasive marker of GI involvement in acute GVHD.

Abstract
As almost all patients with high-risk neuroblastomas have autograft, we aimed to determine if minimal residual disease (MRD) quantified by RT-PCR for tyrosine hydroxylase in PBSC is prognostic in neuroblastomas. PBSC harvests from 38 children were analyzed. Seven had harvests positive for TH-mRNA. Patients with a positive MRD had a lower 2-year-overall-survival compared to those with negative MRD (P = 0.04) regardless of whether or not PBSC were re-infused. Patients in CR/VGPR group with positive MRD have hazard ratio of death at 7.3 [1.3-40.5]. In conclusion, molecular MRD status in PBSC of good response group may be of interest as a survival prognostic factor in high-risk neuroblastomas.
