    Background. Celiac disease (CD) is characterized by elevated serum titers of autoantibodies IgA anti-tissue transglutaminase 2 (TGA-IgA) and IgA anti-endomysial (EMA), with small bowel mucosa atrophy. We evaluated age differences between CD children exhibiting variable antibody titers at diagnosis.MethodsCD children diagnosed between January 2014 and June 2019, according to 2012 ESPGHAN guidelines were studied. All had EMA and TGA-IgA measurements, while a proportion of them underwent esophagogastroduodenoscopy (EGD). Patients were grouped based on serum TGA-IgA titers normalized to the upper limit of normal (ULN) and differences in median age (years) assessed by analysis of variance (ANOVA) and creation of orthogonal contrasts.ResultsCD was diagnosed in 295 subjects (median age: 4.4 [IQR: 2.60-8.52]) with a biopsy sparing protocol (high titer: >= 10xULN) and in 204 by EGD biopsy. Of the latter, 142 (median age: 8.5 [IQR: 5.81-11.06]) and 62 (median age: 9.5 [IQR: 6.26-12.76]) had a low (< 5xULN) and a moderate (>= 5 < 10xULN) TGA-IgA titer, respectively. Potential CD was diagnosed in 20 patients (median age: 3.6 [IQR: 2.47-6.91]). The median age was significantly lower in the no-biopsy group (ANOVA: F-(3,F- 516) = 25.98, p < .001) than in low- and moderate titer groups (p < 0.0001), while there was no statistical difference between biopsy-sparing and potential CD groups.ConclusionCD patients with greatly elevated antibody titers (>= 10xULN) were diagnosed at an earlier age than those with lower titers. This may indicate that an increase in TGA-IgA is independent of age and suggests a polarization of autoimmunity in younger individuals with higher serum antibody levels

    Association between elevated TGA-IgA titers and older age at diagnosis with absence of HBV seroconversion in celiac children

    Patients with celiac disease can have a low rate of protective hepatitis B (HBV) antibody titers after vaccination. We aimed to evaluate the HBV seroconversion in celiac disease (CD) children at the time of diagnosis as well as to identify the presence of possible predictive factors. Celiac disease children were prospectively enrolled and tested for antibodies against the S protein of HBV (HBsAg) at time of diagnosis between January 2009 and February 2020. Based on the serologic response to the vaccine, “responders” and “non-responders” were identified. Statistical analysis has been performed through R statistical software (3.5.1 version, R core Team) Of 96 CD children evaluated, 41.7% (n = 40) showed non-protective or absent antibody titers against HBV. Elevated IgA-antibodies against transglutaminase 2 (TGA-IgA) values and older age at diagnosis were associated with an absent seroconversion to HBV vaccine, while presenting symptoms were not significant. An elevated prevalence of absent seroconversion to HBV vaccine exists in this cohort of CD patients at the time of disease diagnosis. Elevated TGA-IgA titers and older age at diagnosis seem to negatively predict seroconversion. Further studies are needed to identify the real profile of “non-responders”, aiming to organize surveillance and eventual revaccination strategy

    Advancing Creativity Theory and Research: A Socio-cultural Manifesto

    Get PDF
    This manifesto, discussed by 20 scholars, representing diverse lines of creativity research, marks a conceptual shift within the field. Socio-cultural approaches have made substantial contributions to the concept of creativity over recent decades and today can provide a set of propositions to guide our understanding of past research and to generate new directions of inquiry and practice. These propositions are urgently needed in response to the transition from the Information Society to the Post-Information Society. Through the propositions outlined here, we aim to build common ground and invite the community of creativity researchers and practitioners to reflect up, study, and cultivate creativity as a socio-cultural phenomenon

    Burnout among surgeons before and during the SARS-CoV-2 pandemic: an international survey

    Get PDF
    Background: SARS-CoV-2 pandemic has had many significant impacts within the surgical realm, and surgeons have been obligated to reconsider almost every aspect of daily clinical practice. Methods: This is a cross-sectional study reported in compliance with the CHERRIES guidelines and conducted through an online platform from June 14th to July 15th, 2020. The primary outcome was the burden of burnout during the pandemic indicated by the validated Shirom-Melamed Burnout Measure. Results: Nine hundred fifty-four surgeons completed the survey. The median length of practice was 10 years; 78.2% included were male with a median age of 37 years old, 39.5% were consultants, 68.9% were general surgeons, and 55.7% were affiliated with an academic institution. Overall, there was a significant increase in the mean burnout score during the pandemic; longer years of practice and older age were significantly associated with less burnout. There were significant reductions in the median number of outpatient visits, operated cases, on-call hours, emergency visits, and research work, so, 48.2% of respondents felt that the training resources were insufficient. The majority (81.3%) of respondents reported that their hospitals were included in the management of COVID-19, 66.5% felt their roles had been minimized; 41% were asked to assist in non-surgical medical practices, and 37.6% of respondents were included in COVID-19 management. Conclusions: There was a significant burnout among trainees. Almost all aspects of clinical and research activities were affected with a significant reduction in the volume of research, outpatient clinic visits, surgical procedures, on-call hours, and emergency cases hindering the training. Trial registration: The study was registered on clicaltrials.gov "NCT04433286" on 16/06/2020

    Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

    Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

    Emozioni e stati d'animo durante il lockdown: un focus sulla plusdotazione

    No full text
    La ricerca si è focalizzata sulle manifestazioni emotive nei bambini durante il lockdown de-rivante dalla diffusione del COVID-19. Un caso particolare è rappresentato dalla popola-zione di soggetti plusdotati, che presentano spesso un'elevata e più intensa sensibilità emo-tiva. È stato proposto un questionario costruito ad hoc compilato da 126 madri che hanno risposto riferendosi ad ognuno dei propri figli (N = 225), sia con plusdotazione sia con svi-luppo tipico. La prima fase di analisi dei dati ha considerato un gruppo di bambini apparte-nenti a famiglie con almeno un figlio con plusdotazione (N = 162) e un gruppo di bambini con sviluppo tipico (N = 63). Dalle analisi non emergono differenze significative tra i due gruppi, sia rispetto alle emozioni, sia agli stati d'animo; tuttavia, ulteriori analisi che con-frontano i bambini con plusdotazione (N = 100) con bambini con sviluppo tipico (N = 125) a prescindere dalla famiglia di appartenenza, mostrano come i primi sembrano sperimentare maggiori livelli di apatia (p meno di .001) e di insofferenza (p uguale a .016) rispetto ai pari normotipici
