Abstract Allergic rhinitis (AR) is the most frequent IgE-mediated disease, mainly in children and adolescents. Management of AR in the pediatric age may be heterogeneous, and the available guidelines do not adequately consider this issue. As a result, the Italian Society of Pediatric Allergy and Immunology (SIAIP) promoted a Delphi Consensus to define and evaluate the most relevant aspects of AR management in the pediatric setting in Italy. A qualified board of experts prepared a list of statements that a panel of Italian experts voted on using a web platform. Forty-two pediatricians participated. The results showed that all statements had consensus (> 80% of scores 4 + 5). In particular, there was awareness that AR is a type 2 inflammatory disease requiring adequate treatment. Topical drugs should be preferred, as they are better with cycles. Combined antihistamine/corticosteroid is also considered effective and safe in adolescents. In conclusion, AR deserves adequate attention and care. Current medications are safe and effective; treatment should be addressed to dampen type 2 inflammation and relieve complaints.

Group A Streptococcus infection ,GAS ,Children ,Pharyngitis ,Antibiotics ,Influenza ,Pediatrics ,RJ1-570 - Abstract
Abstract Background Despite the worldwide increasing incidence of Group A Streptococcus (GAS) infections reported since December 2022, data on noninvasive GAS (nGAS) infections in the post COVID-19 era are limited. By a self-reported survey performed in an outpatient setting, we investigated the number and clinical features of GAS infections, the diagnostic work-up and the type of treatment utilized. In addition, the rate of influenza vaccination was evaluated. Methods In June 2023 family pediatricians involved in the study sent the survey to parents of patients aged 0–16 years. The survey included questions on GAS infections that occurred from January 1 to May 31, 2023. Results Among 3580 children, 20.3% had a GAS infection (0,8% < 1 year, 16,4% 1–3 years, 42,3% 3–6 years, 26,5% 6–9 years, 11,4%, 9–12 years, and 2,6% 12–16 years). Symptoms reported were sore throat (76.9%), fever (75.2%), tonsillar exudate (25.2%), lymphadenopathy (21.8%), and scarlet fever (14.7%). A single patient was hospitalized due to GAS meningitis. Twenty four percent of children had more than one GAS infection. In this group, frequencies of symptoms reported in the first and in the following infection were similar, except for fever and scarlet fever which were less frequent during relapses. GAS was identified by rapid antigen detection test in 81.0% of children. Eighty-nine per cent of children were treated with antibiotics, mostly amoxicillin/clavulanate (40.4%) and amoxicillin (39.4%). Thirty four percent of children received influenza vaccine. No difference was observed among immunized and not immunized regarding the number and characteristics of GAS infection. Conclusions We reported a certain prevalence of nGAS infections in children, mainly those aged 3–6 years age, who were mostly characterized by a low score of symptoms, and in most of the cases diagnosed and treated using a microbiological test as confirmatory tool. In this new clinical setting, a national study would be useful to reach more significant data for the definition of a correct diagnosis and clinical management of nGAS infections in children. Moreover, it is important to improve flu vaccination campaign and coverage to protect children from coinfections that could worsen the disease and misdiagnose the etiology of pharyngitis.

While Trisomy X syndrome is typically characterized by developmental and cognitive variations, it is not commonly associated with immunodeficiencies. We report the unique case of a 6-year-old girl with Trisomy X presenting with selective IgA deficiency, challenging the conventional understanding of this chromosomal condition. The patient exhibited recurrent respiratory infections and gastrointestinal symptoms, evaluated in the context of her genetic background of Trisomy X and significantly low levels of IgA (0.03 g/L), yet normal IgG and IgM levels. Immunological assessment revealed a poor response to vaccination to HBV, necessitating an adapted vaccination strategy. Gastrointestinal investigations indicated paradoxical diarrhea secondary to chronic constipation, managed with dietary interventions. The presence of an extra X chromosome raises questions about the potential over-expression of genes that escape X-chromosome inactivation, such as FOXP3, which is crucial for the regulation of regulatory T cells. An abnormal expression of FOXP3 could lead to either heightened immune regulation, increasing susceptibility to infections, or to immune dysregulation. Although Trisomy X is not typically associated with immunodeficiencies, this case, paralleled by another patient with Trisomy X and CVID, suggests a need for further speculative research into possible genetic links. Moreover, a 1969 study reported lower IgA levels in women with an extra X chromosome. In conclusion, this case aims to underscore the necessity for a deeper genetic and immunological evaluation in chromosomal anomalies like Trisomy X to fully understand their speculative impact on immune function.

Gut microbiota plays an important role in maintaining respiratory health while providing protection against respiratory illnesses. However, the clinical role of probiotic strains in prevention and treatment of early-onset asthma is still debated. The present study aims to systematically review the available literature on the efficacy of probiotic supplementation, either alone or in combination with other treatments, in managing children with asthma. An electronic search was conducted across multiple databases including PubMed, Web of Science, and EMBASE. The articles reported in English, regardless of year of publication, were reviewed by independent authors for inclusion assessment. Randomized controlled studies evaluating the efficacy of probiotics in children with asthma were included in the study. Of the 203 articles reviewed, 16 were selected and summarized to provide a consistent review, and of these, eight studies reported the anti-asthmatic effects of the treatment with single and multi-strain probiotics alone, seven reported the use of probiotic strains in combination with other treatments, and one was a follow-up study. While some of the studies reported are well conducted and with promising results, no cumulative significant impact was seen for probiotic supplementation on disease parameters of asthma in children. However, the available literature is not sufficient to draw any solid conclusion about the possible use of probiotics in children with asthma, and it is necessary to expand this literature by conducting more well-designed randomized clinical trials to assess the effects of probiotic strains in children with asthma or carrying a high-risk of asthma.

Background: Subjects with mutations in the Ataxia-Telangiectasia mutated (ATM) gene encoding for ATM kinase have a greater predisposition to develop atherosclerosis, but the mechanism behind this phenomenon is not yet understood. NADPH oxidase type 2 may play a role in this process, leading to endothelial dysfunction and an increased susceptibility to thrombosis. The purpose of this study was to assess the redox state in individuals with ATM mutations and determine its impact on endothelial function. Methods: In this cross-sectional study, twenty-seven children with ataxia telangiectasia (AT) (13 males and 14 females, mean age 15.1 ± 7.6 years) were compared with 27 controls (13 males and 14 females, mean age 14.6 ± 8.4 years) matched for age and gender. Additionally, 29 AT parents with heterozygous mutation of ATM (h-ATM) gene, and 29 age- and gender-matched controls were included. Endothelial function was evaluated through brachial flow-mediated dilation (FMD) and the assessment of nitric oxide (NO) bioavailability. Oxidative stress was evaluated by measuring serum activity of soluble NOX2-dp (sNOX2-dp), hydrogen peroxide (H2O2) production, and hydrogen breakdown activity (HBA). Thrombus formation was assessed through the Total Thrombus Formation Analysis System (T-TAS). Results: AT children and parents with heterozygous ATM mutations exhibited significantly lower FMD, HBA, and NO bioavailability as compared to age and gender matched controls. AT children and ATM carrier of heterozygous ATM mutations had significantly higher concentrations of sNOX2-dp and H2O2 as compared to controls. Compared to the respective controls, AT children and their parents, who carried heterozygous ATM mutation, showed an accelerated thrombus growth as revealed by reduced occlusion time. Multivariable linear regression analysis revealed that sNOX2 (standardized coefficient β: −0.296; SE: 0.044; p = 0.002) and NO bioavailability (standardized coefficient β: 0.224; SE: 0.065; p = 0.02) emerged as the only independent predictive variables associated with FMD (R2: 0.44). Conclusions: This study demonstrates that individuals with ATM mutations experience endothelial dysfunction, increased oxidative stress, and elevated thrombus formation. These factors collectively contribute to the heightened susceptibility of these individuals to develop atherosclerosis.

Background: Seasonal allergic rhinoconjunctivitis (SAR) is a worldwide health problem, especially in Westernized countries. Previous studies of the “Panallergens in Pediatrics” (PAN-PED) cohort found that molecular spreading (ie, the progressive increase in serum specific IgE antibody levels) of the IgE response to the grass pollen, Phleum pratense, molecules is directly associated with polysensitization to pollen in general.The research question is aimed at verifying whether this association can also be detected for non-pollen allergens, specifically Dermatophagoides pteronyssinnus (D.pt), to better understand the relationship between a perennial allergen (D.pt) and a seasonal allergen (Phleum pratense).To this end, our first objective was to analyze the biobank of the PAN-PED cohort serum by measuring the IgE levels to D.pt and its major recombinant molecules (Der p1, Der p2, Der p23); subsequently we investigated their correlation towards Phleum pratense IgE response, studying also the relationship between the molecular spreading of these 2 different allergens. Methods: Among 1120 patients positive to Phleum pratense, 638 were also sensitized to D.pt. Patients underwent skin prick tests (SPT) for inhalant extracts, and their serum was tested for total IgE (tIgE), and sIgE to pollen and perennial allergens. Considering the molecular allergen detection through the component resolved diagnosis (CRD), out of 638 patients, 146 were further investigated by performing IgE tests of the 3 major D.pt. molecules: Der p1, Der p2, and Der p23. Results: We found that a broader molecular response to Phleum pratense molecules, assessed by CRD, was associated with higher tIgE levels, polysensitization to pollens, and higher IgE levels to pollens, but also to lower IgE levels to D.pt and lower degree of sensitization to rDer p1, r Der p2, and rDer p23. In a multivariate linear model, the number of Phleum pratense molecules recognized by IgE was still inversely associated with the IgE level to D.pt extract. Conclusions: The main finding of this study was the detection of an inverse association, never described in the literature, between the molecular spreading of the IgE response to Phleum pratense and the IgE response to D.pt. This led us to speculate on the etiopathogenetic hypothesis according to which, among the majority of pollen allergic patients, a strong and molecularly diversified IgE response may be limited to pollen allergens and may be preventing or contrasting the development of an equally strong and diversified IgE sensitization to D.pt molecules. The biological mechanisms underlying this phenomenon deserve to be investigated.

Abstract Food supplements are defined as foodstuffs the purpose of which is to supplement the normal diet and which are concentrated sources of nutrients or other substances with a nutritional or physiological effect, often referred to as nutraceuticals, may exert benefit to the human body. Their use is increasing worldwide, including Europe and in Italy. However, some doctors are skeptical about their effectiveness and safety. This reluctance may depend on poor knowledge of the mechanisms of action and clinical evidence in literature. The Italian Society of Pediatric Allergy and Immunology (SIAIP) promoted the institution of an ad hoc Committee. The first initiative performed by this Committee was the administration of a questionnaire to the members of SIAIP. The results of this survey provided interesting results. Most pediatricians know the food supplement concept but frequently need help understanding the mechanisms of action. Most prescribe food supplements, mainly for preventing infections or enhancing immune defense. In addition, they prefer to use food supplements as cycles or add-on therapy. Finally, most participants like to attend events on this issue and contribute to new evidence through trials. In conclusion, this survey underscores the relevance of food supplement issues and attests to interest in this topic. However, there is a need to provide information and promote studies on this matter.

Abstract Resveratrol is a nonflavonoid polyphenolic compound with a chemical structure consisting of two aromatic rings linked by a methylene bridge. It exists in two primary isomers and has a broad range of desirable biological activities, including antioxidant, anti‐inflammatory, antidiabetic, cardioprotective, and antitumor activities. Some antioxidant properties of resveratrol are known with certainty, such as its potential to positively impact cardiovascular health, inflammation, and the metabolism. On the other hand, many uncertainties and controversies plague its efficacy, including issues related to its bioavailability, dosing, human clinical trial results, interactions with other food components and drugs, and individual variability. In brief, although promising results have been observed in in vitro and in vivo studies, the translation of these findings to human health remains uncertain. Many human clinical trials on resveratrol are ongoing or have proven inconclusive, making it challenging to definitively determine its efficacy for specific health conditions and its dose and duration of treatment. Resveratrol may interact with medications and have varying effects on individuals. In conclusion, it is essential to approach resveratrol with a balanced perspective, consulting with healthcare professionals, and considering the evolving scientific evidence when making decisions regarding its clinical use.

- Abstract
The Italian Disciplinary section of Test of Competences (TECO-D) project is an important longitudinal study used to analyze learning outcomes of ungraded students and to measure quality of the educational process. The aim of the present study was to evaluate the psychometric properties of the TECO-D in students enrolled in the Bachelor's Degree in Pediatric Nursing at "Sapienza" University of Rome. The other aim was to evaluate if TECO-D is able to assess the changes in skills between students of I and III year of the university course and to calculate the minimal detectable change. The sample was composed by 35 pediatric nursing students and was recruited in October 2019. The test was administered using a digital platform with multiple choice questions (MCQs). The reliability, as internal consistency, was excellent ([alpha]= 0.938). The responsiveness evaluated by t-test for independent samples, the Standard Error of Measurement (SEM) and Minimal Detectable Change (MDC) was supported by significant differences between two cohorts of pediatric nursing students, and adequate TECO-D is a reliable instrument for assessing the skills of pediatric nursing student evaluating the achievement of university goals and improving the quality of the training provided by the university.

Food allergy (FA) affects approximately 6–8% of young children, with a peak prevalence at approximately one year of age. Tree nut and peanut allergies are among the main causes of anaphylaxis in the world. The gold standard for the diagnosis of FAs is the oral food challenge (OFC). Other diagnostic tests used in the clinical practice are skin prick tests (SPTs) and laboratory tests to measure out the presence of serum specific IgE (sIgE). In this narrative review, we collect the current evidence of the predictive value (PV) of SPTs and sIgE for the outcome of the OFCs. In literature, data are conflicting as to whether increasing sIgE concentration and wheal size in SPTs correlate with OFC outcomes. Most studies included in our review have shown that in vivo and in vitro tests may predict OFC outcomes with variable PV, but data are not conclusive; therefore, the OFC currently remains the gold standard for FA diagnosis.

Physics ,QC1-999 - Abstract
The recently proposed zero-added-loss multiplexing (ZALM) source of entangled photons enables higher efficiency in entanglement distribution than spontaneous parametric down-conversion sources and can be carried out using both space-to-ground and ground-to-ground links. We demonstrate the flexibility of ZALM architectures to be adapted to alternative entanglement distribution protocols. Focusing on the counterintuitive result that entanglement can be generated between distant parties without using any entanglement as a resource, we analyze two protocols for entanglement distribution to memories via separable states. Modeling them in a ZALM setup, we consider the effects of noise both in the communication channels and in the memories. We thereby identify the optimal protocol to use with respect to the highest entanglement generated, given the noise conditions of the network.

Objective: To determine the effect of grit-blasting before and after sintering on the surface roughness of zirconia and the micro-tensile bond strength of a pressable veneering ceramic to zirconia. Methods: Pre-sintered zirconia blocks (IPS e.max ZirCAD, Ivoclar) were divided into four test groups of three specimens each and a control group (‘CTR’; no surface treatment). Pre-S-30, Pre-S-50, and Pre-S-110 were grit-blasted with 30-µm SiO2-coated Al2O3, 50-µm Al2O3 and 110-µm Al2O3 particles, respectively, before sintering. Post-S-30 was grit-blasted with 30-µm SiO2-coated Al2O3 after sintering. For each treatment, the surface roughness was measured (Ra, Perthometer M4P, Mahr Perthen). After sintering the zirconia blocks, a liner was applied and a pressable ceramic (IPS e.max ZirPress, Ivoclar) was heat-pressed. Sixteen microbars were obtained from each block and submitted to micro-tensile bond-strength (µTBS) testing. Data were analyzed with one-way ANOVA. Any correlation between Ra and µTBS was evaluated (Sperman test). Results: Grit-blasting before sintering with 110-µm Al2O3 (RaPre-S-110 = 3.4 ± 0.4 µm), 50-µm Al2O3 (RaPre-S-50 = 2.3 ± 0.5 µm), and 30-µm SiO2-coated Al2O3 (RaPre-S-30 = 1.2 ± 0.2 µm) resulted in significantly higher roughness than grit-blasting after sintering with 30-µm SiO2-coated Al2O3 (RaPost-S-30 = 0.5 ± 0.1 µm). The highest µTBS was measured when the sintered zirconia was grit-blasted with 30-μm SiO2-coated Al2O3 (µTBSPost-S-30 = 28.5 ± 12.6 MPa), which was significantly different from that of specimens that were grit-blasted before sintering (µTBSPre-S-30 = 21.8 ± 10.4; µTBSPre-S-50 = 24.1 ± 12.6; µTBSPre-S-110 = 26.4 ± 14.1) or were not grit-blasted (µTBSCTR = 20.2 ± 11.2). Conclusions: Grit-blasting zirconia before sintering enhanced the surface roughness proportionally to the particle size of the sand used. Grit-blasting with 30-µm SiO2-coated Al2O3 after sintering improved bonding of the veneering ceramic to zirconia. Clinical Significance: As grit-blasting with 30-µm SiO2-coated Al2O3 after sintering improved bonding of the veneering ceramic to zirconia, it may reduce veneering ceramic fractures/chipping.

Abstract Enzymatic hydrolysis of sugar beets is an efficient alternative to conventional hot water extraction where overall soluble extraction is valued. The economic analysis of a sugar beet soluble sugar production plant was designed and developed using SuperPro Designer software. The commercial scale operation was sized to process 100 million metric ton (MT)/day of sugar beets. The base case process includes transportation, grinding, thermal pretreatment, enzymatic hydrolysis, solid–liquid separation, and evaporation. The final product from the model was assumed to be a sugar syrup stream at 65% total solids content. Since the breakeven selling price was sensitive to the cost of enzymes, alternative scenario A added an ultrafiltration unit operation to separate the enzymes and reuse them in subsequent batches of hydrolysis. Steam was another major contributor to the operating cost. Alternative scenario B included a natural gas boiler to generate steam from biogas produced from a co‐located dairy manure digester. The breakeven selling price of the sugar syrup from the base case, alternative scenario A, and alternative scenario B were $965, $911, and $955 per metric ton, respectively. Sensitivity analysis showed that the breakeven selling price is sensitive to the raw material cost, especially for the pectic enzymes.

This cross-sectional study aimed to contribute to the definition of Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections (PANDAS) pathophysiology. An extensive immunological assessment has been conducted to investigate both immune defects, potentially leading to recurrent Group A β-hemolytic Streptococcus (GABHS) infections, and immune dysregulation responsible for a systemic inflammatory state. Twenty-six PANDAS patients with relapsing-remitting course of disease and 11 controls with recurrent pharyngotonsillitis were enrolled. Each subject underwent a detailed phenotypic and immunological assessment including cytokine profile. A possible correlation of immunological parameters with clinical-anamnestic data was analyzed. No inborn errors of immunity were detected in either group, using first level immunological assessments. However, a trend toward higher TNF-alpha and IL-17 levels, and lower C3 levels, was detected in the PANDAS patients compared to the control group. Maternal autoimmune diseases were described in 53.3% of PANDAS patients and neuropsychiatric symptoms other than OCD and tics were detected in 76.9% patients. ASO titer did not differ significantly between the two groups. A possible correlation between enduring inflammation (elevated serum TNF-α and IL-17) and the persistence of neuropsychiatric symptoms in PANDAS patients beyond infectious episodes needs to be addressed. Further studies with larger cohorts would be pivotal to better define the role of TNF-α and IL-17 in PANDAS pathophysiology.

In this thesis, we discuss aspects of the simulation, characterisation, and control of the dynamics of open quantum systems. The latter are systems governed by quantum mechanical laws and interacting with an environment, which is typically much larger than the system itself. According to the standard approach, one is usually able to perform a suitable average over the environmental degrees of freedom, resulting in an effective description of the main system dynamics, which accounts for the effects of the interaction with the surroundings. In standard scenarios, usually studied within the so-called Born-Markov approximation, the system-environment coupling is weak and such that we can perform a neat separation of timescales: the environmental dynamics is assumed to be fast compared to the typical evolution timescale of the system of interest. However, nowadays we are able to inspect physical scenarios where the usual Born-Markov approximation breaks down: the interaction between system and environment can be strong, likely leading to non-negligible memory (non-Markovian) effects. In this work, we discuss some instances in which we cannot work in the standard Born-Markov regime. We introduce and analyse some numerical and analytical techniques to characterise and simulate non-standard scenarios. We show that, even in the Markovian regime, the traditional formulation of thermodynamic irreversibility shows flaws and inconsistencies. We thus use phase-space methods to assess the role of initial correlations shared by the two parties of a bipartite harmonic system in the entropy production rate, including non-Markovian effects. Furthermore, we show that certain interactions enable to redraw the boundaries between the system and the environment in an effective manner, resulting in a new picture where the system degrees of freedom are augmented, while the residual environment is rearranged in such a way that the Born-Markov approximation is recovered. This analytical technique, known as reaction coordinate mapping approach, is employed in this work to show that, upon an accurate choice of the parameter regime, a spin-boson model can serve as a quantum analogue simulator of non-Markovian multiphoton Jaynes-Cummings models. These systematic studies shed light on the thermodynamic characterisation of open quantum systems, as well as on their numerical simulation.

Physics ,QC1-999 - Abstract
The formalism of linear response theory can be extended to encompass physical situations where an open quantum system evolves toward a nonequilibrium steady state. Here, we use the framework put forward by Konopik and Lutz [Phys. Rev. Res. 1, 033156 (2019)2643-156410.1103/PhysRevResearch.1.033156] to go beyond unitary perturbations of the dynamics. Considering an open system comprised of two coupled quantum harmonic oscillators, we study the system's response to unitary perturbations, affecting the Hamiltonian dynamics, as well as nonunitary perturbations, affecting the properties of the environment, e.g., its temperature and squeezing. We show that linear response, combined with a quantum probing approach, can effectively provide valuable quantitative information about the perturbation and characteristics of the environment, even in cases of nonunitary dynamics.

Spectral densities encode the relevant information characterizing the system–environment interaction in an open-quantum system problem. Such information is key to determining the system’s dynamics. In this work, we leverage the potential of machine learning techniques to reconstruct the features of the environment. Specifically, we show that the time evolution of a system observable can be used by an artificial neural network to infer the main features of the spectral density. In particular, for relevant examples of spin-boson models, we can classify with high accuracy the Ohmicity parameter of the environment as either Ohmic, sub-Ohmic or super-Ohmic, thereby distinguishing between different forms of dissipation.

Since the discovery of graphene, there has been a wide range of the literature dealing with its versatile structure and easy binding of biomolecules as well as its large loading capacity. In the emerging field of immunotherapy, graphene and its derivatives have potential uses as drug delivery platforms directly into tumour sites or as adjuvants in cancer vaccines, as they are internalized by monocytes which in turn may activate adaptive anti-tumoral immune responses. In this study, we expose cells of the innate immune system and a human acute monocytic leukemia cell line (THP-1) to low doses of small-sized GO nanosheets functionalized with bovine serum albumin (BSA) and fluorescein isothiocyanate (FITC), to study their acute response after internalization. We show by flow cytometry, uptake in cells of GO-BSA-FITC reaches 80% and cell viability and ROS production are both unaffected by exposure to nanoparticles. On the contrary, GO-BSA nanosheets seem to have an inhibitory effect on ROS production, probably due to their antioxidant properties. We also provided results on chemotaxis of macrophages derived from peripheral blood monocytes treated with GO-BSA. In conclusion, we showed the size of nanosheets, the concentration used and the degree of functionalization were important factors for biocompatibility of GO in immune cells. Its low cytotoxicity and high adaptability to the cells of the innate immune system make it a good candidate for deployment in immunotherapy, in particular for delivering protein antigens to monocytes which activate adaptive immunity.

Primary complement system (C) deficiencies are rare but notably associated with an increased risk of infections, autoimmunity, or immune disorders. Patients with terminal pathway C-deficiency have a 1,000- to 10,000-fold-higher risk of Neisseria meningitidis infections and should be therefore promptly identified to minimize the likelihood of further infections and to favor vaccination. In this paper, we performed a systematic review about clinical and genetic patterns of C7 deficiency starting from the case of a ten-year old boy infected by Neisseria meningitidis B and with clinical presentation suggestive of reduced C activity. Functional assay via Wieslab ELISA Kit confirmed a reduction in total C activity of the classical (0.6% activity), lectin (0.2% activity) and alternative (0.1% activity) pathways. Western blot analysis revealed the absence of C7 in patient serum. Sanger sequencing of genomic DNA extracted from peripheral blood of the patient allowed the identification of two pathogenetic variants in the C7 gene: the already well-characterized missense mutation G379R and a novel heterozygous deletion of three nucleotides located at the 3’UTR (c.*99_*101delTCT). This mutation resulted in an instability of the mRNA; thus, only the allele containing the missense mutation was expressed, making the proband a functional hemizygote for the expression of the mutated C7 allele.

Deficiency of adenosine deaminase 2 (DADA2) is a rare systemic autoinflammatory disease, typically with autosomal recessive inheritance, usually caused by biallelic loss of function mutations in the ADA2 gene. The phenotypic spectrum is broad, generally including fever, early-onset vasculitis, stroke, and hematologic dysfunction. Heterozygous carriers may show related signs and symptoms, usually milder and at an older age. Here we describe the case of two relatives, the proband and his mother, bearing an ADA2 homozygous pathogenic variant, and a heterozygous son. The proband was a 17-year-old boy with intermittent fever, lymphadenopathies, and mild hypogammaglobulinemia. He also had sporadic episodes of aphthosis, livedo reticularis and abdominal pain. Hypogammaglobulinemia was documented when he was 10 years old, and symptoms appeared in his late adolescence. The mother demonstrated mild hypogammaglobulinemia, chronic pericarditis since she was 30 years old and two transient episodes of diplopia without lacunar lesions on MRI. ADA2 (NM_001282225.2) sequencing identified both mother and son as homozygous for the c.1358A>G, p.(Tyr453Cys) variant. ADA2 activity in the proband and the mother was 80-fold lower than in the controls. Clinical features in both patients improved on anti-tumor necrosis factor therapy. An older son was found to be heterozygous for the same mutation post-mortem. He died at the age of 12 years due to a clinical picture of fever, lymphadenitis, skin rash and hypogammaglobulinemia evolving toward fatal multiorgan failure. Biopsies of skin, lymph nodes, and bone marrow excluded lymphomas and vasculitis. Despite being suspected of symptomatic carrier, the contribution of an additional variant in compound heterozygosity, or further genetic could not be ruled out, due to poor quality of DNA samples available. In conclusion, this familiar case demonstrated the wide range of phenotypic variability in DADA2. The search for ADA2 mutations and the assessment of ADA2 activity should be considered also in patients with the association of hypogammaglobulinemia and inflammatory conditions, also with late presentation and in absence of vasculitis. Furthermore, the clinical picture of the deceased carrier suggests a possible contribution of heterozygous pathogenic variants to inflammation.

ABSTRACT Purpose: To evaluate the quality of breast reconstruction service at a university hospital, as assessed by the patients. Methods: This cross-sectional study enrolled adult women who underwent immediate or delayed breast reconstruction by any technique performed at a university hospital between 1 and 24 months before the assessment. The Brazilian version of the Health Service Quality Scale (HSQS) was self-applied to the participants. The HSQS produces percentage scores, which are expressed in values ranging from 0 to 10 for each domain of the scale, and into an overall percentage quality score. The management team was asked to establish a minimum satisfactory score for the breast reconstruction service. Results: Ninety patients were included. The management team considered 8.00 the minimum satisfactory score for the service. The overall percentage score was 93.3%. Only one domain, ‘Support,’ had an average score lower than that considered satisfactory (7.22 ± 3.0); while the others had higher scores. The domain that scored highest was ‘Qualification’ (9.94 ± 0.3), followed by ‘Result’ (9.86 ± 0.4). There was a positive correlation between ‘type of oncologic surgery’ and ‘intentions of loyalty to the service’ (ρ = 0.272; p = 0.009) and a negative correlation between ‘education’ and ‘quality of the environment’ (ρ = –0.218; p = 0.039). The higher the patient’s level of education, the higher the score attributed to ‘relationship’ (ρ = 0.261; p = 0.013) and the lower the score of ‘aesthetics and functionality’ (ρ = –0.237; p = 0.024). Conclusions: The quality of the breast reconstruction service was considered satisfactory, but there is a demand for structural improvements, better interpersonal relationships, and a stronger support network for patients.

Abstract By combining qualitative scenarios and life cycle assessment (LCA), we place the latter in a larger context. This study outlines the importance of the integration of future perspectives into LCA, and also the significance of taking changes in the environment of technology into account, rather than just technological development itself. Accordingly, we focused on adapting the background system of an attributional LCA in the agri-food sector. The proposed technology was assumed not have evolved in the considered time horizon. In this context, the objectives of this paper were twofold: (i) to methodologically prove the applicability of integrating qualitative scenarios into LCA and (ii) to focus on changes in the background system, which is sometimes overlooked in the context of future-oriented LCA. This allowed to evaluate the future potential of different technologies, assessing their environmental impact under uncertain future developments. Methodologically, the qualitative information from scenarios was transformed into quantitative data, which was successively fed into the life cycle inventory (LCI) of the LCA approach. This point of integration into the second phase of LCA translates into future changes in the entire environment in which a technology is used. This means that qualitatively described scenario narratives need to be converted into value estimates in order to be incorporated into the LCA model. A key conclusion is that changes in the background of an LCA—the changing framework expressed through the inventory database—can be very important for the environmental impact of emerging technologies. This approach was applied to a food processing technology to produce apple juice. The proposed methodology enables technology developers to make their products future-proof and robust against socioeconomic development. In addition, the market perspective, if spelled out in the scenarios, can be integrated, leading to a more holistic picture of LCA with its environmental focus, while simultaneously empowering actors to make the right strategic decisions today, especially when considering the long investment cycles in the agri-food sector.

Abstract Background Coronavirus disease 2019 (COVID-19) is a disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Although many reports have detailed a range of neurological symptoms in SARS-CoV-2-infected patients, studies of neuro-ophthalmological manifestations are still scarce. Case presentation We report a 9-year-old girl with abducens nerve palsy after COVID-19 with no evidence of other neurological disease on neuroimaging. At 2-month follow-up clinical conditions were improved. Conclusions The palsy may have occurred due to a possible post-infectious immune-mediated mechanism underlying the neuropathy, as opposed to direct viral infiltration. Despite being rare, this complication must be taken into account.

Abstract Background COVID-19 lockdown caused sudden changes in people’s lifestyle, as a consequence of the forced lockdown imposed by governments all over the world. We aimed to evaluate the impact of lockdown on body mass index (BMI) in a cohort of allergic children and adolescents. Methods From the first of June until the end of October 2020, we submitted a written questionnaire to all the patients who, after lockdown, carried out a visit at the Pediatric Allergy Unit of the Department of Mother-Child, Urological Science, Sapienza University of Rome. The questionnaire was composed by 10 questions, referring to the changes in their daily activities. Data were extrapolated from the questionnaire and then analyzed considering six variables: BMI before and BMI after lockdown, sugar intake, sport, screens, sleep, and anxiety. Results One hundred fifty-three patients agreed to answer our questionnaire. Results showed a statistically significant increase in the BMI after lockdown (20.97 kg/m2 ± 2.63) with respect to the BMI before lockdown (19.18 kg/m2 ± 2.70). A multivariate regression analysis showed that the two variables that mostly influenced the increase in BMI were sleep and anxiety. Conclusions For the analyzed cohort of allergic children and adolescents we obtained significant gain in BMI as consequences of lockdown, which can be explained by many factors: high consumption of consolatory food, less sport activities, more time spent in front of screens, sleep alteration associated with increased anxiety. All these factors acted together, although sleep alteration and increased anxiety were the most influential factors that led to the worsening or the onset of weight gain, creating the basis for future health problems.

Abstract Background The SARS-CoV-2 outbreak pushed the Italian government to start a strict lockdown, replacing school attendance with long-distance learning. This caused reduced exposure to sunlight but increased exposure to screens. Vernal keratoconjunctivitis (VKC) is a chronic inflammatory ocular condition in which exposure to light plays a cardinal role. We conducted an online survey to evaluate the impact of screen exposure on children with VKC during the COVID-19 lockdown. Methods We performed a survey-based observational study, asking patients followed at the Allergology clinics of Meyer Children’s University Hospital in Florence and of Policlinico Umberto I in Rome to provide grading on 6 subjective ocular clinical manifestations presented during the lockdown and to give an estimate of their hours/day of screen exposure. Results Mean scores of signs and symptoms increased homogeneously when studying patients exposed to longer screen time. When comparing scores collected in 2019 to those in 2020, there was not a significant reduction in clinical manifestations, although the situation differed between the two centers due to geographical differences in sunlight exposure. Conclusion During the lockdown, there was a reduction in sunlight exposure but conversely an increase in the time spent in front of screens that correlated with the worsening of VKC signs and symptoms in direct proportion to the hours/day of screen exposure. Our results also showed a statistically significant difference in the relative impact of long-distance learning on VKC clinical manifestations in the different Italian regions.

- Abstract
Allergic rhinitis (AR) is the most frequent IgE-mediated disease, mainly in children and adolescents. Management of AR in the pediatric age may be heterogeneous, and the available guidelines do not adequately consider this issue. As a result, the Italian Society of Pediatric Allergy and Immunology (SIAIP) promoted a Delphi Consensus to define and evaluate the most relevant aspects of AR management in the pediatric setting in Italy. A qualified board of experts prepared a list of statements that a panel of Italian experts voted on using a web platform. Forty-two pediatricians participated. The results showed that all statements had consensus (> 80% of scores 4 + 5). In particular, there was awareness that AR is a type 2 inflammatory disease requiring adequate treatment. Topical drugs should be preferred, as they are better with cycles. Combined antihistamine/corticosteroid is also considered effective and safe in adolescents. In conclusion, AR deserves adequate attention and care. Current medications are safe and effective; treatment should be addressed to dampen type 2 inflammation and relieve complaints.
