    Background: Separation anxiety (SA) can be defined as the fear reaction and protest manifested by children when the main caregivers move away from him/her or in front of unfamiliar person. SA near eight months may be considered as an important and normal phase of the correct and typical social neurodevelopment. Aims of the present pilot study is assessing the prevalence of separation anxiety in a population of patients with migraine without aura (MwA). Materials and methods: 119 children (69 males) suffering from MwA (mean age 1.78 ± 7:59) were consecutively recruited. The control population consisted of 231 (114 males) healthy subjects similar for age (7.64 ± 1:34; p = 0.768) and gender (p=0.987) The Screen for child anxiety related emotional disorders (SCARED) test was used to assess the prevalence of separation anxiety among MwA children. Results: Healthy individuals are on average less affected (mean 4.72 ± 0:32) of the Separation Anxiety Disorder respect of MwA children (mean 6.83 ± 0.97; p < 0.001) (Figure 1). Conclusion. MwA presents many psychiatric comorbidities and among ones separation anxiety may be considered in the clinical and therapeutic management of pediatric primary headache

    Global Value Chains During the Great Trade Collapse: A Bullwhip Effect?

    Get PDF
    This paper analyzes the performance of global value chains during the trade collapse. To do so, it exploits a unique transaction-level dataset on French firms containing information on cross-border monthly transactions matched with data on worldwide intra-.rm linkages as defined by property rights (multinational business groups, hierarchies of firms). This newly assembled dataset allows us to distinguish firm-level transactions among two alternative organizational modes of global value chains: internalization of activities (intra- group trade/trade among related parties) or establishment of supply contracts (arm's length trade/trade among unrelated parties). After an overall assessment of the role of global value chains during the trade collapse, we document that intra-group trade in intermediates was characterized by a faster drop followed by a faster recovery than arm's length trade. Amplified fluctuations in terms of trade elasticities by value chains have been referred to as the "bullwhip effect" and have been attributed to the adjustment of inventories within supply chains. In this paper we first con.rm the existence of such an effect due to trade in inter- mediates, and we underline the role that different organizational modes can play in driving this adjustment.trade collapse, multinational firms, global value chains, hierarchies of firms, vertical integration

    Endoluminal calprotectin measurement in assessment of pouchitis and a new index of disease activity. A pilot study

    Get PDF
    Pouchitis is the most common complication following proctocolectomy with ileal pouch-anal anastomosis for ulcerative colitis (UC). To provide a standardized definition of pouchitis clinical, endoscopic and histological markers were grouped and weighted in the pouch disease activity index (PDAI). However, the delay in the assessment of the final score due to the time requested for histological analysis remains the main obstacle to the index implementation in clinical practice so that the use of modified-PDAI (mPDAI) with exclusion of histologic subscore has been proposed. We tested the ability of calprotectin measurement in the pouch endoluminal content to mimic the histologic score as defined in the PDAI, the index that we adopted as gold standard for pouchitis diagnosis. Calprotectin was measured by ELISA in the pouch endoluminal content collected during endoscopy in 40 consecutive patients with J-pouch. In each patient PDAI and mPDAI were calculated and 15% of patients were erroneously classified by mPDAI. ROC analysis of calprotectin values vs. acute histological subscore 3 identified different calprotectin cut-off values with corresponding sensitivity and specificity allowing the definition and scoring of different range of calprotectin subscores. We incorporated the calprotectin score in the mPDAI obtaining a new score that shows the same specificity as PDAI for diagnosis of pouchitis and higher sensitivity when compared with mPDAI. The use of the proposed new score, once validated in a larger series of patients, might be useful in the early management of patients with symptoms of pouchitis

    Objectives: Primary monosymptomatic nocturnal enuresis (PMNE) is a common problem in childhood and studies about the sleep habits of affected children are not conclusive. Work-family conflict (WFC) results from the incompatibility between family demands and business/workplace needs. WFC can impact parental quality with many consequences on children health. Aim of study is assessing the prevalence of sleep disturbances in enuretic children, sons of work-shifters. Materials and methods: 80 children (67 males) aged 5-13 years (mean 10,43; SD \ub1 1,99), were consecutively referred for PMNE. Sleep habits were investigated with Sleep Disturbances Scale for Children (SDSC) and the results were compared with a control group of 255 (190 males) typical developing children (TDC) sons of no shift-workers, matched for age (mean 10.57 SD \ub1 1,89; p = 0.569) and sex distribution (Chi-square= 2.416; p = 0.120). Results: To evaluate statically differences among mean values of two samples, the Chi-square test was performed. Logistic regression was assessed to verify the role of paternal shift-working as risk factor for sleep disorders. p=0.05. All sleep disturbances categories were more prevalent in PMNE children sons of shift-workers than control group (Chi-square= 43.926; p<0.001); particularly 82.5% of PMNE vs. 11.76% of TDC show pathological scores for SBD category (Chi-square = 145.592; p<0.001; OR = 35,35; IC95% = 17.71-70.57); 61.25% vs 9.41% for SWTD (Chi-square = 93; p < 0.001; OR = 15.213; IC95% = 8.21-28.15); 57.5% vs 9.41% for DA (Chi-square = 82.31; p < 0.001; OR = 13.02; IC95% = 7.06-23.98); 37.5% vs 6.67% for DIMS (Chi-square = 45.476; p < 0.001; OR = 8,4; IC95% = 4.3-16.39); 26.25% vs 5.88% for SHY (Chi-square = 24.257; p < 0.001; OR = 5.69; IC95% = 2,76-11,71) and 25%c vs 5.49% for DOES (Chi-square = 23.323; p < 0.001; OR = 5,73; IC95% = 2,73-12,01). Conclusions: Our findings suggest that paternal shif-working plus PMNE children may be a relevant factor affecting sleep quality in affected children

    Introduction: The sinactive developmental model provides suggests a different way for the brain study by observing the children behavior. In all neurodevelopmental disorders, we can observe autonomic alteration comprising sleep disorders, meal behaviour alteration and self-regulatory impairment. These alterations/impairment are very frequent in autism spectrum disorders (ASD) (1-12). Aim of the present preliminary study is the assessment of metabolic rate in children affected by ASD. Material s and methods. 5 males affected by ASD aged 7-10 years (mean age 6.73\ub13:39), were recruited. The average score at the ADOS scale was 12.24 (SD\ub1 3.29). The control group consisted of 5 males typically developing children (TDC) aged 7 to 11 years (mean age 7.92 \ub1 3.23). Autonomic/Metabolic evaluation: Free-living daily physical activity was measured using either the SenseWear Armband in order to calculate the total energy expenditure (TEE), baseline (REE) and the metabolic physical activity for prolonged periods of time. In general, the SenseWear Armband allows objective monitoring of the lifestyle including duration and sleep efficiency. Results: ASD subjects show values of total energy expenditure (p = 0.0047) and active energy expenditure (p = 0.044) significantly higher compared to control subjects (Table 1). In addition, ASD children have a metabolic intermediate significantly higher than healthy subjects (p=0.015). (Table 1). Finally, the ASD children show a significant reduction of sleep time (p = 0.027) (Table 1). Conclusion: ASD can represents a very significant risk factor for developing sleep disorders and to high energy expenditure, although further studies are needed in this respect

    Get PDF
    Introduction: Obstructive sleep apnea syndrome (OSAS) affects up to 4% of pediatric population, with many co-morbidities in the medium-long term. Functional alterations in prefrontal cortex (PFC) may explain why OSAS impacts aspects such as: executive functions, memory, motor control, attention, visual-spatial skills, learning and mood regulation. Emotional intelligence (EI) is a complex neuropsychological function that could be impaired in many clinical conditions. Aim of the study is to evaluate the difference in emotional intelligence skills among children with OSAS and healthy subjects Materials and methods: 29 children (16 males) mean age 9.5 \ub1 1.54 years, affected by OSAS were compared with 60 typical developing children similar for gender (p = 0,871), age (p = 0,934) and socio-economic status (p = 0.714). Bar-On emotional quotient inventory, youth version (EQ-i: YV) was used in order to assess the Emotional Quotient. Results: Apnea/hypopnea index (AHI) results to be 8.76 \ub13.45 with medium desaturation index (ODI) amounting to 2:52 \ub1 21.5, average saturation 92.7\ub14.8 %, average desaturation 4.9 %. OSAS children have significant differences in Interpersonal scales (84.95 \ub1 07.03 vs. 99.61 \ub1 8.96; p <0.001), Adaptability (7:36 \ub1 79.61 vs. 101.32 \ub1 9.4; p <0.001), Stress Management (72.48 \ub1 8.14 vs. 98.44 \ub1 5.19, p <0.001), QE Total (81.28 \ub1 11.03 vs. 102.14 \ub1 9.62; p <0.001). Pearson correlation analysis shows an inverse relationship between QE total and ODI (p <0.01). Conclusion: Our findings tend to highlight the role of intermittent hypoxia in OSAS effects genesis, involving also aspects different from physical impairments

    Introduction: Anxiety is the psychological process by which the individual reacts to dangerous external stimuli, triggering responses (mediated by norepinephrine, GABA and serotonin) involving physiological reactions and cognitive strategies. Anxiety can be differentiated in state anxiety and trait anxiety. Fragile X Syndrome (FXS) is a disorder most commonly caused by a triplet repeat expansion of > 200 cytosine-guanine-guanine (CGG) repeats in the 50 untranslated region of the Fragile X mental retardation 1 (FMR1) gene. Aim of the present study is investigating the state or trait anxiety in a sample of mothers of children affected by X-fragile. Materials and methods: 84 mothers (mean age 48.36 \ub1 7.11) of children affected by FXS were recruited and compared with mother of 171 typical developing children (mean age 46.18 \ub1 9.53). The Scale State-Trait Anxiety Inventory for Adults (STAI) was used in order to assess the anxiety levels. Results: All mothers of children affected by FXS showed high score of anxiety levels at the STAI evaluation (Table 1), with no differences were found between mothers of males and females children affected. Conclusions: Mothers of children with FXS appear to be in a state of anxiety effects and suddenly even higher than those found later in mothers of children with other chronic diseases

    We hypothesize that melanocortin receptors (MC) could activate tissue protective circuit in a model of streptozotocin- (STZ-) induced diabetic retinopathy (DR) in mice. At 12–16 weeks after diabetes induction, fluorescein angiography (FAG) revealed an approximate incidence of 80% microvascular changes, typical of DR, in the animals, without signs of vascular leakage. Occludin progressively decreased in the retina of mice developing retinopathy. qPCR of murine retina revealed expression of two MC receptors, Mc1r and Mc5r. The intravitreal injection (5 \u1d707L) of the selective MC1 small molecule agonist BMS-470539 (33 \u1d707mol) and the MC5 peptidomimetic agonist PG-901 (7.32 nM) elicited significant protection with regular course and caliber of retinal vessels, as quantified at weeks 12 and 16 after diabetes induction. Mouse retina homogenate settings indicated an augmented release of IL-1\u1d6fc, IL-1\u1d6fd, IL-6, MIP-1\u1d6fc, MIP-2\u1d6fc, MIP-3\u1d6fc, and VEGF from diabetic compared to nondiabetic mice. Application of PG20N or AGRP and MC5 and MC1 antagonist, respectively, augmented the release of cytokines, while the agonists BMS-470539 and PG-901 almost restored normal pattern of these mediators back to nondiabetic values. Similar changes were quantified with respect to Ki-67 staining. Finally, application of MC3-MC4 agonist/antagonists resulted to be inactive with respect to all parameters under assessment
