Abstract
OBJECTIVES Neck pain is extremely common and represents a substantial economic burden to our society. We aimed to investigate risk factors for nondisabling and disabling neck pain in a large cohort of Italian adolescents with a cross-sectional study. DESIGN Six thousand two hundred eighty-one students (14-19 yrs old) answered an online questionnaire, investigating the following: anthropometric data, lifestyle-related items, neck pain frequency and intensity, need for medical examination, and several risk factors. Students who had to give up social activities because of neck complaints constituted the disabling neck pain group. RESULTS Our findings revealed that sex, age, sports practice, hours of sleep, and family history were risk factors ( P < 0.001) for neck pain in our cohort. Moreover, disabling neck pain group experienced neck pain more frequently ( P < 0.001) and with higher levels of pain ( P < 0.001) compared with the nondisabling group. The number of hours of sleep was the only risk factor that showed a trend to differ comparing the disabling neck pain group with the nondisabling neck pain one ( P = 0.057). CONCLUSIONS Different risk factors for neck pain were detected in a very large cohort of adolescents. This study may pave the way for future prospective studies and for the development of preventive strategies for neck pain in adolescents.

Abstract
Abstract
Predicting the future performance of young runners is an important research issue in experimental sports science and performance analysis. We analyse a dataset with annual seasonal best performances of male middle distance runners for a period of 14 years and provide a modelling framework that accounts for both the fact that each runner has typically run in 3 distance events (800, 1,500, and 5,000 m) and the presence of periods of no running activities. We propose a latent class matrix-variate state space model and we empirically demonstrate that accounting for missing data patterns in runners’ careers improves the out of sample prediction of their performances over time. In particular, we demonstrate that for this analysis, the missing data patterns provide valuable information for the prediction of runner’s performance.

Abstract
Rhabdomyosarcoma (RMS) is an aggressive pediatric soft tissue sarcoma characterized by a very poor prognosis when relapses occur after front-line therapy. Therefore, a major challenge for patients’ management remains the identification of markers associated with refractory and progressive disease. In this context, cancer autoantibodies are natural markers of disease onset and progression, useful to unveil novel therapeutic targets. Herein, we matched autoantibody profiling of alveolar RMS (ARMS) patients with genes under regulatory control of PAX3-FOXO1 transcription factor and revealed fibroblast growth factor 8 (FGF8) as a novel ARMS tumor antigen of diagnostic, prognostic, and therapeutic potential. We demonstrated that high levels of FGF8 autoantibodies distinguished ARMS patients from healthy subjects and represented an independent prognostic factor of better event-free survival. FGF8 was overexpressed in ARMS tumors compared to other types of pediatric soft tissue sarcomas, acting as a positive regulator of cell signaling. Indeed, FGF8 was capable of stimulating ARMS cells migration and expression of pro-angiogenic and metastasis-related factors, throughout MAPK signaling activation. Of note, FGF8 was found to increase in recurrent tumors, independently of PAX3-FOXO1 expression dynamics. Risk of recurrence correlated positively with FGF8 expression levels at diagnosis and reduced FGF8 autoantibodies titer, almost as if to suggest a failure of the immune response to control tumor growth in recurring patients. This study provides evidence about the crucial role of FGF8 in ARMS and the protective function of natural autoantibodies, giving new insights into ARMS biology and laying the foundations for the development of new therapeutic strategies.

Abstract
BACKGROUND Many nonconclusive studies have been conducted on low back pain (LBP) in adolescents and associated factors. OBJECTIVE The aim was to assess the lifetime prevalence and associated factors of LBP in adolescents. MATERIALS AND METHODS A questionnaire was administered in high school students (14-19-yr-old participants) in Veneto region (Italy). The self-administered, structured questionnaire included anthropometric data; psychologic factors and lifestyle; presence, intensity, and family history of LBP; referral to professional health care for LBP; and a short version of the International Physical Activity Questionnaire. RESULTS A total of 6281 adolescents were recruited; 5204 questionnaires were included in the final analysis. A total of 2549 (48.98%) students reported one or more LBP episodes and 723 (13.89%) reported nonspecific disabling lumbar pain (i.e., no underlying pathology); 1040 (41.11%) subjects with LBP consulted a healthcare professional. A significant association emerged for LBP with sex (female), positive family history, time spent sitting or using electronic devices, sleep deprivation (<5 hrs/night), and low level of physical activity. CONCLUSION In a large sample of adolescents, LBP lifetime prevalence is high and often associated with disabling pain and sedentary lifestyle, requiring professional care. These findings may support the development of prevention and treatment strategies of LBP in adolescents, reducing the risk of developing chronic pain.

Abstract
Alveolar rhabdomyosarcoma (ARMS) is a highly aggressive subtype of childhood cancer for which efficacious treatments are needed. Immunotherapy represents a new therapeutic opportunity to pursue, but it requires the identification of worthwhile tumor antigens. Herein, we exploited the capacity of ARMS autoantibodies to recognize tumor self-antigens, probing human protein microarrays with plasma from ARMS patients and healthy subjects. We assessed the autoantibody response in ARMS, validated data with independent techniques, and estimated autoantibodies diagnostic and prognostic significance by receiver-operator characteristic curves (ROC), uni- and multivariate analysis. Of the 48 tumor antigens identified, General Transcription Factor II-I (GTF2i) and Protocadherin Gamma Subfamily C5 (PCDHGC5) were selected as candidate targets to validate tumor-restricted antigen expression and autoantibody reactivity through an independent technique and wider cohort of cases. GTF2i and PCDHGC5 overexpression was observed in tumor tissues compared to normal counterparts, and anti-GTF2i and -PCDHGC5 autoantibodies were found able to distinguish ARMS patients from healthy subjects as well as cases with different histology. Moreover, low levels of PCDHGC5 autoantibodies characterized patients with worse event-free survival and proved to be an independent negative prognostic factor. This approach provided the first comprehensive autoantibody profile of ARMS, gave novel insights into the immune response of this malignancy and paved the way toward novel potential antibody-based therapeutic applications suitable to improve the survival of ARMS patients.

Abstract
Falls are the second most frequent cause of injury in the elderly. Physiological processes associated with aging affect the elderly's ability to respond to unexpected balance perturbations, leading to increased fall risk. Every year, approximately 30% of adults, 65 years and older, experiences at least one fall. Investigating the neurophysiological mechanisms underlying the control of static and dynamic balance in the elderly is an emerging research area. The study aimed to identify cortical and muscular correlates during static and dynamic balance tests in a cohort of young and old healthy adults. We recorded cortical and muscular activity in nine elderly and eight younger healthy participants during an upright stance task in static and dynamic (core board) conditions. To simulate real-life dual-task postural control conditions, the second set of experiments incorporated an oddball visual task. We observed higher electroencephalographic (EEG) delta rhythm over the anterior cortex in the elderly and more diffused fast rhythms (i.e., alpha, beta, gamma) in younger participants during the static balance tests. When adding a visual oddball, the elderly displayed an increase in theta activation over the sensorimotor and occipital cortices. During the dynamic balance tests, the elderly showed the recruitment of sensorimotor areas and increased muscle activity level, suggesting a preferential motor strategy for postural control. This strategy was even more prominent during the oddball task. Younger participants showed reduced cortical and muscular activity compared to the elderly, with the noteworthy difference of a preferential activation of occipital areas that increased during the oddball task. These results support the hypothesis that different strategies are used by the elderly compared to younger adults during postural tasks, particularly when postural and cognitive tasks are combined. The knowledge gained in this study could inform the development of age-specific rehabilitative and assistive interventions.

Abstract
Metastatic tumours of the hand are rare, and therefore, is the subject of only a few publications in the literature. We report on three new cases along with a retrospective and descriptive study with file and literature analysis dating from 1900 to 2017, which reported on 337 studies. To perform the statistical analysis, ordinary lease square regression was used to group the metastases into distal phalanx, proximal/middle phalanx, thumb, hand and carpus. We found 564 metastases at the hand for a total of 482 patients. Of the reported cases, 60% were male. The average age was 59 years. The main primary cancers were lung cancer (40%), followed by gastrointestinal (19%), genito-urinary (13%), gynaecological (11%) and ear, nose and throat (6%) cancers. The mean survival time was 7.2 months. Fifty-nine per cent was bone metastasis, 18% tissue metastasis and 3% cutaneous metastasis. In 20% of cases, the type of metastasis was not mentioned. Of all the tissue metastases, 47 (54%) were subungual and in that group, the thumb was the finger most commonly affected. Overall, metastases most commonly appeared in the distal phalanx, which can be explained by a greater vascularisation as well as microtraumatisms. Survival was independent of the epidemiological criteria and of the location and type of metastasis. Patients with primary urological cancer lived on average 3 months longer than patients with other types of primary cancers.

Abstract
Fibromyalgia syndrome (FMS) is a complex pain disorder, characterized by diffuse pain and cognitive disturbances. Abnormal cortical oscillatory activity may be a promising biomarker, encouraging non-invasive neurostimulation techniques as a treatment. We aimed to modulate abnormal slow cortical oscillations by delivering transcranial alternating current stimulation (tACS) and physiotherapy to reduce pain and cognitive symptoms. This was a double-blinded, randomized, crossover trial conducted between February and September 2018 at the Rehabilitation Unit of a teaching Hospital (NCT03221413). Participants were randomly assigned to tACS or random noise stimulation (RNS), 5 days/week for 2 weeks followed by ad hoc physiotherapy. Clinical and cognitive assessments were performed at T0 (baseline), T1 (after stimulation), T2 (1 month after stimulation). Electroencephalogram (EEG) spectral topographies recorded from 15 participants confirmed slow-rhythm prevalence and provided tACS tailored stimulation parameters and electrode sites. Following tACS, EEG alpha1 ([8-10] Hz) activity increased at T1 (p = 0.024) compared to RNS, pain symptoms assessed by Visual Analog Scale decreased at T1 (T1 vs T0 p = 0.010), self-reported cognitive skills and neuropsychological scores improved both at T1 and T2 (Patient-Reported Outcomes in Cognitive Impairment, T0-T2, p = 0.024; Everyday memory questionnaire, T1 compared to RNS, p = 0.012; Montréal Cognitive Assessment, T0 vs T1, p = 0.048 and T0 vs T2, p = 0.009; Trail Making Test B T0-T2, p = 0.034). Psychopathological scales and other neuropsychological scores (Trail Making Test-A; Total Phonemic Fluency; Hopkins Verbal Learning Test-Revised; Rey-Osterrieth Complex Figure) improved both after tACS and RNS but earlier improvements (T1) were registered only after tACS. These results support tACS coupled with physiotherapy in treating FMS cognitive symptoms, pain and subclinical psychopathology.

Abstract
Rhabdomyosarcoma (RMS) arises from myogenic precursors that fail to complete muscle differentiation and represents the most frequent soft tissue sarcoma in children. Two major histological subtypes are recognized: alveolar RMS, characterized by a more aggressive behavior and a greater proneness to metastasis, and embryonal RMS which accounts for the 80% of cases and carries a better prognosis. Despite the survival of patients with localized tumors has progressively improved, RMS remains a challenging disease especially for metastatic patients and in case of progressive or recurrent disease after front-line therapy. MicroRNAs, a class of small non-coding RNA, have emerged as crucial players in cancer development and progression, and their detection in plasma (circulating miRNAs) represents a promising minimally invasive approach that deserve to be exploited in clinical practice. We evaluated the utility of circulating miRNAs as diagnostic and prognostic biomarkers in children with RMS profiling miRNAs from plasma of a small cohort of RMS patients and healthy donors (HD) using a qPCR Cancer Panel. An assessment of hemolysis status of plasma using miR-451/miR-23a ratio was performed as pre-analytical analysis. Statistical analysis revealed that miRNAs expression pattern clearly distinguished RMS patients from HD (p < 0.05). Interestingly, plasma levels of muscle-specific miR-206 were found to be significantly increased in RMS patients compared to HD, whereas levels of three potential tumor-suppressor miRNAs, miR-26a and miR-30b/30c, were found lower. Reduced levels of circulating miR-26a and miR-30b/c were further measured in an independent larger cohort of patients (validation set) by digital droplet PCR. In particular, we evidenced that miR-26a absolute plasma levels were associated with fusion status and adverse outcome (p < 0.05). Taken together, these findings demonstrate the potential of circulating miRNA as diagnostic and prognostic biomarker in children affected by this malignancy and enforced the key role of miR-26a in pediatric rhabdomyosarcoma.

Abstract
BACKGROUND Patient preferences regarding their involvement in shared treatments decisions is fundamental in clinical practice. Previous evidences demonstrated a large heterogeneity in these preferences. However, only few studies have analysed the influence of patients' individual differences, contextual and situational qualities, and their complex interaction in explaining this variability. METHODS We assessed the role of the interaction of patient's sociodemographic and psychological factors with a physician's gender. Specifically, we focused on patient gender and attitudes toward male or female physicians. One hundred fifty-three people participated in this randomised controlled study and were randomly assigned to one of two experimental conditions in which they were asked to imagine discussing their treatment with a male and a female doctor. RESULTS Analyses showed an interplay between attitude towards women and the gender of patients and doctors, explaining interindividual variability in patient preferences. CONCLUSIONS In conclusion, patients' attitudes toward the physicians' gender constitutes a relevant characteristic that may influence the degree of control patients want to have and the overall patient-physician relationship.

Abstract
BACKGROUND Pediatric oncohematologic patients are a high-risk population for clinical deterioration that might require pediatric intensive care unit (PICU) admission. Several studies have described outcomes and mortality predictors for patients post hematopoietic stem cell transplantation (HSCT), but fewer data exist regarding the category of non-HSCT patients. PROCEDURE All oncohematologic non-HSCT patients ≤18 years requiring PICU admission from 1998 to 2015 in our tertiary-care academic hospital were retrospectively evaluated by means of the pediatric hematology-oncology unit database and the Italian PICUs data network database. We assessed the relation between demographic and clinical characteristics and 90-day mortality after PICU admission. RESULTS Of 3750 hospitalized oncohematologic patients, 3238 were non-HSCT and 63 (2%) of them were admitted to the PICU. Patients were mainly affected by hematological malignancies (70%) and mostly were in the induction-therapy phase. The main reasons for admission were respiratory failure (40%), sepsis (25%), and seizures (16%). The median PICU stay was 5 days (range 1-107). The mortality rate at PICU discharge was 30%, and at 90 days it was 35%. Fifty-five percent of deaths happened in the first 2 days of the PICU stay. Cardiac arrest (P = .007), presence of disseminated intravascular coagulation (DIC, P = .007), and acute kidney injury (AKI) at PICU admission (P < .001) and during PICU stay (P = .021) were significant predictors of mortality in the multivariate analysis. Respiratory failure and mechanical ventilation were not associated with mortality. CONCLUSIONS A relatively small percentage of non-HSCT patients required PICU admission, but the mortality rate was still high. Hemodynamic instability, DIC, and AKI, but not respiratory failure, were significant predictors of mortality.

Abstract
Abnormal cortical oscillations are markers of Parkinson's Disease (PD). Transcranial alternating current stimulation (tACS) can modulate brain oscillations and possibly impact on behaviour. Mapping of cortical activity (prevalent oscillatory frequency and topographic scalp distribution) may provide a personalized neurotherapeutic target and guide non-invasive brain stimulation. This is a cross-over, double blinded, randomized trial. Electroencephalogram (EEG) from participants with PD referred to Specialist Clinic, University Hospital, were recorded. TACS frequency and electrode position were individually defined based on statistical comparison of EEG power spectra maps with normative data from our laboratory. Stimulation frequency was set according to the EEG band displaying higher power spectra (with beta excess on EEG map, tACS was set at 4 Hz; with theta excess, tACS was set at 30 Hz). Participants were randomized to tACS or random noise stimulation (RNS), 5 days/week for 2-weeks followed by ad hoc physical therapy. EEG, motor (Unified Parkinson's Disease Rating Scale-motor: UPDRS III), neuropsychological (frontal, executive and memory tests) performance and mood were measured before (T0), after (T1) and 4-weeks after treatment (T2). A linear model with random effects and Wilcoxon test were used to detect differences. Main results include a reduction of beta rhythm in theta-tACS vs. RNS group at T1 over right sensorimotor area (p = .014) and left parietal area (p = .010) and at T2 over right sensorimotor area (p = .004) and left frontal area (p = .039). Bradykinesia items improved at T1 (p = .002) and T2 (p = .047) compared to T0 in the tACS group. In the tACS group the Montréal Cognitive Assessment (MoCA) improved at T2 compared with T1 (p = .049). Individualized tACS in PD improves motor and cognitive performance. These changes are associated with a reduction of excessive fast EEG oscillations.

Abstract
We have used energy-filtered photoemission electron microscopy (PEEM) at the photoemission threshold to carry out a microscopic scale characterization of the surface charge and domain structure of the (001) surface in BaTiO3. Signatures of ferroelectric and ferroelastic domains, and tweed, dominate the surface structure of BaTiO3 at room temperature. The surface ferroic signatures are maintained on heating to temperature (~550 K), well above the transition temperature (393 K). This surface proximity effect provides the mechanism for memory of the bulk ferroelectric domain arrangement up to 150 K above TC and thus can be considered as a robust fingerprint of the ferroelectric state near the surface. Self-reversal of polarization is observed for the tweed below TC and for the surface domains above TC. Annealing at higher temperature triggers the dynamic tweed which in turn allows a full reorganization of the ferroic domain configuration.

Abstract
To describe incidence, causes, and outcomes related to pediatric intensive care unit (PICU) admission for patients undergoing hematopoietic stem cell transplantation (HSCT), we investigated the risk factors predisposing to PICU admission and prognostic factors in terms of patient survival. From October 1998 to April 2015, 496 children and young adults (0 to 23 years) underwent transplantation in the HSCT unit. Among them, 70 (14.1%) were admitted to PICU. The 3-year cumulative incidence of PICU admission was 14.3%. The main causes of PICU admission were respiratory failure (36%), multiple organ failure (16%), and septic shock (13%). The overall 90-day cumulative probability of survival after PICU admission was 34.3% (95% confidence interval, 24.8% to 47.4%). In multivariate analysis, risk factors predisposing to PICU admission were allogeneic HSCT (versus autologous HSCT, P = .030) and second or third HSCT (P = .018). Characteristics significantly associated with mortality were mismatched HSCT (P = .011), relapse of underlying disease before PICU admission (P < .001), acute respiratory distress syndrome at admission (P = .012), hepatic failure at admission (P = .021), and need for invasive ventilation during PICU course (P < .001). Our data indicate which patients have a high risk for PICU admission after HSCT and for dismal outcomes after PICU stay. These findings may provide support for the clinical decision-making process on the opportunity of PICU admission for severely compromised patients after HSCT.

Abstract
INTRODUCTION Villonodular synovitis (VNS) is a rare disease with an incidence of 1.8 per 1,000,000 inhabitants. VNS of the ankle has seldom been described and evaluated given its extreme rarity (2.5% of VNS cases). It presents an 11% recurrence rate. We report a continuous retrospective series with the main objective of clinically and radiologically evaluating these ankles searching for any risk factors of recurrence. At revision the study's main endpoint was the existence of local recurrence (radiological and clinical) and the secondary endpoint was the existence of tibiotalar osteoarthritis. The working hypothesis was that recurrence could be subclinical, warranting systematic imaging studies during follow-up. MATERIAL AND METHODS The study was retrospective, conducted on seven patients (six males) whose mean age was 42 years treated over a period of 9 years (two diffuse forms and five localized forms). The initial treatment consisted in synovectomy via the conventional approach. Four patients also received adjuvant isotopic synoviorthesis treatment. The revision was clinical (MMTS, AOFAS, and OMAS scores) and radiological (standard and MRI) to evaluate the joint after-effects and search for recurrence. RESULTS Six patients were seen at a mean 6.5 years of follow-up. One case of early recurrence (4 years) was noted, with a major clinical manifestation because it was associated with joint destruction requiring arthrodesis, and one case of late asymptomatic recurrence (9 years), diagnosed radiologically on the follow-up MRI. The functional results remained good at follow-up (MMTS 77%, AOFAS 71, OMAS 71). Five of the six patients returned to their daily activities. At revision, no sign of osteoarthritis was observed. No risk factor for recurrence was demonstrated. DISCUSSION/CONCLUSION The hypothesis was confirmed with the existence of asymptomatic recurrence at revision, underscoring the value of systematic MRI at follow-up. Other than major joint destruction, the prognosis remains good even in case of recurrence. The literature emphasizes the existence of an initial diffuse form and partial surgical resection as risk factors of recurrence. None of the reports in the literature has proven that adjuvant treatment, whose modalities do not meet with consensus, reduces this risk. LEVEL OF EVIDENCE Retrospective series, level IV.

Abstract
Rankings of scholarly journals based on citation data are often met with scepticism by the scientific community. Part of the scepticism is due to disparity between the common perception of journals' prestige and their ranking based on citation counts. A more serious concern is the inappropriate use of journal rankings to evaluate the scientific influence of researchers. The paper focuses on analysis of the table of cross-citations among a selection of statistics journals. Data are collected from the Web of Science database published by Thomson Reuters. Our results suggest that modelling the exchange of citations between journals is useful to highlight the most prestigious journals, but also that journal citation data are characterized by considerable heterogeneity, which needs to be properly summarized. Inferential conclusions require care to avoid potential overinterpretation of insignificant differences between journal ratings. Comparison with published ratings of institutions from the UK's research assessment exercise shows strong correlation at aggregate level between assessed research quality and journal citation 'export scores' within the discipline of statistics.

Abstract
The emerging fields of graphene-based magnetic and spintronic devices require a deep understanding of the interface between graphene and ferromagnetic metals. This paper reports a detailed investigation at the nanometer level of the Fe-graphene interface carried out by angle-resolved photoemission, high-resolution photoemission from core levels, near edge X-ray absorption fine structure, scanning tunnelling microscopy and spin polarized density functional theory calculations. Quasi-free-standing graphene was grown on Pt(111), and the iron film was either deposited atop or intercalated beneath graphene. Calculations and experimental results show that iron strongly modifies the graphene band structure and lifts its π band spin degeneracy.

Abstract
We report on a 19-year-old male patient with a rare injury: a basis fracture of the second metacarpal with avulsion of the extensor carpi radialis longus (ECRL) tendon. The patient was treated with open reduction and internal plate fixation of the fragment. The functional results after 10 months of follow-up were pronation/supination 90/0/90° (90/0/90°), extension/flexion 70/0/70° (70/0/70°) radial/ulnar duction 20/0/40° (25/0/40°), bilateral grip strength was 115 kPa. The patient suffered no pain at all. The Mayo wrist score reached 100 points. Radiologically, the fracture was consolidated.Consistent diagnostics and surgical therapy lead to functional and radiological recovery following fracture of the second metacarpal base with avulsion of the extensor carpi radialis longus tendon.

Abstract
Both optical and electrochemical graphene-based sensors have gone through rapid development, reaching high sensitivity at low cost and with fast response time. However, the complex validating biochemical operations, needed for their consistent use, currently limits their effective application. We propose an integration strategy for optoelectrochemical detection that overcomes previous limitations of these sensors used separately. We develop an optoelectrochemical sensor for aptamer-mediated protein detection based on few-layer graphene immobilization on selectively modified fluorine-doped tin oxide (FTO) substrates. Our results show that the electrochemical properties of graphene-modified FTO samples are suitable for complex biological detection due to the stability and inertness of the engineered electrodic interface. In addition, few-layer immobilization of graphene sheets through electrostatic linkage with an electrochemically grafted FTO surface allows obtaining an optically accessible and highly conductive platform. As a proof of concept, we used insulin as the target molecule to reveal in solution. Because of its transparency and low sampling volume (a few microliters), our sensing unit can be easily integrated in lab-on-a-chip cell culture systems for effectively monitoring subnanomolar concentrations of proteins relevant for biomedical applications.

Abstract
The study of the determinants of fights between animals is an important issue in understanding animal behavior. For this purpose, tournament experiments among a set of animals are often used by zoologists. The results of these tournament experiments are naturally analyzed by paired comparison models. Proper statistical analysis of these models is complicated by the presence of dependence between the outcomes of fights because the same animal is involved in different contests. This paper discusses two different model specifications to account for between-fights dependence. Models are fitted through the hybrid pairwise likelihood method that iterates between optimal estimating equations for the regression parameters and pairwise likelihood inference for the association parameters. This approach requires the specification of means and covariances only. For this reason, the method can be applied also when the computation of the joint distribution is difficult or inconvenient. The proposed methodology is investigated by simulation studies and applied to real data about adult male Cape Dwarf Chameleons.
