Separaxion anxiety in pediatric migraine without aura: A pilot study

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

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

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

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

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

A prototype of fine granularity lead-scintillating fiber calorimeter with imaging read out

The construction and tests performed on a smal prototype of lead-scintillating fiber calorimeter instrumented with multianode photomultipliers are reported. The prototype is 15 cm wide, 15 radiation lenghts deep and is made of 200 layers of 50 cm long fibers. One side of the calorimeter has been instrumented with an array of 3 × 5 multianode R8900-M16 Hamamatsu photomultipliers, each segmented with a matrix of 4 × 4 anodes. The read-out granularity is 240 pixels 11 × 11 mm 2 reading about 64 fibers each. They are interfaced to the 6 × 6 mm 2 pixelled photocade with truncated pyramid light guides made of BC-800 plastic, UV transparent. Moreover each photomultiplier provides also the OR information of the last 12 dynodes. This information can be useful for trigger purposes. The response of the individual anodes, their relative gain and cross-talk has been measured with a 404 nm picosecond laser illuminating only a few fibers on the opposite side of the read-out. We also present first results of the calorimeter response to cosmic rays and electron beam data collected at BTF facility in Frascati

Paternal shift-working and sleep disorders in children affected by primary nocturnal enuresis

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

Anxiety levels in mothers of children affected by x-fragile syndrome

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

Autonomic Regulation In Autism Spectrum Disorders

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

Characterization of prevalence and genetic subtypes of Blastocystis sp. in wild and domestic Suidae of central Italy aided by amplicon NGS

Blastocystis spp. is a common single-celled intestinal symbiont, comprising several genetic subtypes (ST) and trans- missible by animal-to-animal, human-to-human, animal-to-human and, possibly, human-to-animal routes. This work was designed to explore the presence of Blastocystis in sympatric domestic and wild suids and their ability to carry zoonotic STs, in a condition of widespread opportunity to come in contact with the microorganism through their shared water and food resources, and other carriers. We sampled 42 and 37 stool samples from wild boars and domestic pigs, respectively. STs were first identified by PCR followed by Sanger sequencing. Sequences represented in double-band PCR products or in Sanger chromatograms displaying multiple peaks, were resolved by next generation sequencing (NGS). Twenty-six (61.9%) wild boar and 26 (70.2%) pig samples were PCR-positive, respectively. ST3, ST5 and ST15 were found in 3.8%, 38.4% and 80.8% of the positive wild boars and 11.5%, 88.5%, 11.5% of the positive pigs, respectively. ST1 was found only in pigs (3.8%). STs 5 and 15 were common in both groups of animals, but in reversed proportions, suggesting preferential colonization. We found significantly different ST distributions among wild boars and domestic pigs. This might indicate that lifestyle differences between the two populations influence their risk for contracting certain subtypes, or that ST5 and ST15 can colonize preferentially wild or domestic animals. Based on the STs described here, wild boars and domestic pigs can act as reservoirs with zoonotic potential. The ability of suids to carry zoonotic STs appears to be higher when using NGS than Sanger sequencing, and resolution of complex sequencing profiles is imperative before excluding the presence of STs of human concern
