RESUMO
SARS-CoV-2 typically causes mild symptoms in children, but evidence suggests that persistent immunopathological changes may lead to long COVID (LC). To explore the interplay between LC and innate immunity, we assessed the type I interferon (IFN-I) response in children and adolescents with LC symptoms (LC; n = 28). This was compared with age-matched SARS-CoV-2 recovered participants without LC symptoms (MC; n = 28) and healthy controls (HC; n = 18). We measured the mRNA expression of IFN-I (IFN-α/ß/ε/ω), IFN-I receptor (IFNAR1/2), and ISGs (ISG15, ISG56, MxA, IFI27, BST2, LY6E, OAS1, OAS2, OAS3, and MDA5) in PBMCs collected 3-6 months after COVID-19. LC adolescents (12-17 years) had higher transcript levels of IFN-ß, IFN-ε, and IFN-ω than HC, whereas LC children (6-11 years) had lower levels than HC. In adolescents, increased levels of IFN-α, IFN-ß, and IFN-ω mRNAs were found in the LC group compared with MC, while lower levels were observed in LC children than MC. Adolescents with neurological symptoms had higher IFN-α/ß mRNA levels than MC. LC and MC participants showed decreased expression of ISGs and IFNAR1, but increased expression of IFNAR2, than HC. Our results show age-related changes in the expression of transcripts involved in the IFN-I signaling pathway in children and adolescents with LC.

AIM: Emergency room admissions have decreased globally during the COVID-19 pandemic, particularly for respiratory diseases. We evaluated hospital admissions for respiratory diseases in the first year of the Italian pandemic and compared them with the corresponding period in 2016-2017. METHODS: The study was carried out at the Sapienza University in Rome, Italy, and covered 9 March to 28 February 2020-2021 and 2016-2017. We tested 85 hospitalised children who were negative for the virus that causes COVID-19 in 2020-2021 and compared them with 476 hospitalised children from 2016-2017, as we had also tested nasal washing samples for 14 respiratory viruses during that period. RESULTS: Hospitalisations for acute respiratory tract infections were 82.2% lower in 2020-2021 than 2016-2017. The respiratory syncytial virus (RSV) and several other viruses were detected less frequently during the pandemic. An extraordinary finding was that rhinoviruses remained seasonal. In 2020-2021, we detected a virus in 54.1% of the hospitalised children: rhinoviruses in 41, RSV in 4 and other viruses in 1. This was significantly lower than the 71.6% in 2016-2017: RSV in 130, rhinoviruses in 128 and other viruses in 83. CONCLUSION: Pandemic measures dramatically reduced childhood respiratory infections, particularly RSV, but were less effective at reducing rhinoviruses.

BACKGROUND: Community-acquired pneumonia (CAP) represents one of the most common infectious diseases among children. Diagnosis of CAP is mainly clinical. Chest X-ray (CXR) remains the gold standard for the diagnosis in severe or controversial conditions. Recently, some authors have focused on the application of ultrasound in lung diseases but the role of lung ultrasound (LUS) in the diagnosis of CAP is still debated. We aimed to study the concordance between LUS and CXR in evaluating specific signs of CAP. As a secondary aim, we sought to determine the sensitivity and specificity of LUS in CAP diagnosis compared with CXR. Finally, we evaluated the role of LUS during the follow up. METHODS: We enrolled 68 children (<16 years old) hospitalized from October 2018 to September 2019 with a clinical and radiological diagnosis of CAP (cases: N = 41), or with no respiratory diseases (controls: N = 27), in whom a CXR was performed for clinical indications. All the children underwent LUS during hospitalization. The average time needed to perform LUS was 5-10 min for each child, and 19/41 cases were re-evaluated by LUS and CXR 30 days after discharge. RESULTS: Lung ultrasound confirmed CAP diagnosis in 40/41 patients. Concordance between the two techniques was K = 0.88 for the right lung and K = 0.70 for the left lung. Lung ultrasound showed a sensitivity of 97% and a specificity of 96% compared with CXR. At the follow up, sensitivity increased to 100% while specificity was 94%. CONCLUSIONS: Our study showed a potential benefit of LUS compared with CXR in the diagnosis and the follow up of CAP.

BACKGROUND: The term "sharenting" describes the increasingly popular habit of parents to share photos, videos, or other information regarding their children on their social profiles, through online platforms. It is highly likely that many parents are posting content about their underage children online with little knowledge of the risks associated with this practice. This study aims to investigate whether variables such as parents' age, gender, marital status, occupation and educational level influence the practice of sharing child-related content and the degree of awareness. METHODS: We performed a pilot cross-sectional study, based on an anonymous questionnaire. The questionnaire was administered to parents of underage children attending the pediatric outpatient clinic of the Umberto I Hospital, Sapienza University, in Rome, Italy, by researchers, through the google forms platform; qualitative variables were generated on excel sheets and a statistical analysis was performed on SPSS Ibm-statistics using the chi-square test. RESULTS: Two hundred twenty-eight parents of children under 18 years of age completed the questionnaire (82% mothers, 18% fathers); 98% of the respondents used social media and 75% of them published their children's related content online. Thirty-one percent of the compilers started their practice of sharenting in the first 6 months of life of their child. Our analysis showed that compared to parents who do not post online, parents who usually post online their children are significantly more likely to be partial employees or unemployed (p = 0,002), with lower educational level (p = 0,05), younger (less than 35 years of age (p = 0,01)) and have a higher number of followers (p < 0,001). Finally, 93% of the compilers were not aware of the current legislation and of the risks related to the practice of sharenting. CONCLUSIONS: Pediatricians, healthcare assistants and preventive healthcare professionals should play a central role in alerting parents and families to the risks of sharenting; the results of our study could draw their attention to the increasing practice of sharenting and make healthcare professionals active part in the protection of children.

BACKGROUND: Our aim was to hypothesize that the COVID-19 pandemic influenced the characteristics of viral bronchiolitis by comparing the last 3 epidemics with 3 pre-COVID-19 epidemics in infants hospitalized with bronchiolitis. METHODS: We prospectively enrolled 637 consecutive infants (median age 3.0 ± 2.1 months, 58.5% males), hospitalized for bronchiolitis during 6 consecutive annual epidemic seasons from 2017 to 2023. All parents of the children were given a structured anamnestic questionnaire. A nasopharyngeal aspirate was tested for 15 respiratory viruses. As measures of severity, we evaluated the O 2 supplementation and the admission at the pediatric intensive care unit. RESULTS: A total of 166 were hospitalized with bronchiolitis in 2017-2018, 97 in 2018-2019, 69 in 2019-2020, 0 in 2020-2021, 129 in 2021-2022 and 176 in 2022-2023. Taking together the 332 bronchiolitis cases hospitalized during the 3 prepandemic seasons, they peaked between December and January; after the flat curve in 2020-2021, the cases of bronchiolitis peaked in November 2021 and in December 2022. While the 2021-2022 season registered a less severe clinical presentation, O 2 supplementation and pediatric intensive care unit admissions increased in 2022-2023 with respect to the prepandemic seasons ( P < 0.001). CONCLUSIONS: This study represents an important scientific demonstration of the impact of primary prevention measures on the epidemiology of viral infections; their fluctuations were related to the intensity of restrictive measures and to the changing trend of respiratory viruses. It is essential to predict the real temporal trend of bronchiolitis not to leave high-risk children uncovered and to guide hospitals to maintain a high level of readiness.

INTRODUCTION: Although impaired lung function after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been described in adults, it is unclear whether lung function might be altered in children, especially among asymptomatic or mildly symptomatic patients. In this study, we report the results of lung function testing performed after SARS-CoV-2 infection in a large pediatric population. METHODS: The study included 589 patients with previous confirmed SARS-CoV-2 infection aged 0-18 years. Both symptomatic and asymptomatic patients during acute infection were enrolled in the study. A spirometry was performed in all cooperating patients. RESULTS: The mean age of enrolled patients was 9.6 years and the mean time from infection to enrollment was 171 days. Spirometry was performed and deemed evaluable in 433 patients. No patient had reduced forced vital capacity (FVC) and only 14 patients (3.2%) had a forced expiratory volume in the First second (FEV1) < 80%. The mean spirometry values recorded were in the normal range. There were no statistically significant differences in spirometry values between patients with respiratory symptoms during infection and those without. Similarly, there were no differences in spirometry parameters according to the time elapsed between infection and enrollment. CONCLUSION: Lung function, according to spirometry values, does not appear to be impaired long after infection in the pediatric population. The presence of respiratory symptoms during SARS-CoV-2 infection would not represent a risk factor for impaired lung function in this cohort of patients.

BACKGROUND: The Order of Physicians and Dentists of the Province of Rome aims at focusing on the satisfaction of healthcare personnel as an essential factor for the quality of medical care in the health sector. The aim of this study is to assess and prioritize the factors that can be linked to a higher or lower degree of job satisfaction in Primary Care Pediatricians (PCPs). METHODS: This study is a cross sectional survey. A questionnaire was administered to all primary care pediatricians registered to the Order, exploring in particular the work activity organization, the level of satisfaction in their professional life, and the level of perceived health. A pilot activity was conducted to validate the questionnaire. Fisher exact test and ordinal logistic regression (ologit) models were used for the univariate and multivariate analysis. RESULTS: The highest level of job dissatisfaction, in both men and women, was found to be in the practice type without any form of association; among women, it reached an even higher level for those who had their own practice at a distance of 20-40 km from their home. Women, compared to men, maintained a lower level of job satisfaction also while working in Pediatric Primary Care Units (PPCUs). In PPCUs, for the same distance, females showed a more similar pattern to males. Men working in PPCUs, regardless of distance, declared a higher degree of job satisfaction. Both men and women, working as a group pediatrician or in PPCUs, did not show a significant difference in the level of job satisfaction. CONCLUSIONS: The study contributes to a deeper understanding of the factors that may influence levels of career satisfaction in female and male PCPs. Therefore, research and interventions regarding job satisfaction should foster an organizational network connection among PCPs for their job and individual well-being, from a perspective of enhancing patient care. A major effort to improve work-life balance and career satisfaction among women is important, suggesting that interventions for improving job satisfaction could benefit from a gender-specific approach.

Children with SARS-CoV-2 are mostly mild symptomatic, but they may develop conditions, such as persisting symptoms, that may put them at greater risk of complications. Our aim was to evaluate the frequency and the presence of risk factors for persisting COVID-19 symptoms in children. We carried out a prospective observational study of the clinical manifestation of Long COVID at the Department of Maternal Infantile Science of a tertiary University hospital in Rome. We included 697 children (0-18 years), with previous SARS-CoV-2 infection. Children and parents were asked questions regarding persistent symptoms of COVID-19. Children with symptoms 30 days after initial diagnosis were 185/697 (26.4%). Moreover, 81/697 (11.6%) patients presented symptoms 90 days after the diagnosis. Thirty-day-persisting symptoms were mostly present in children with anosmia, atopy, asthenia, and cough in the acute phase compared with the asymptomatic children 30 days after infection. After 90 days, symptoms described were mainly neurological (47/697 children, 6.7%), and headache (19/697; 2.7%) was the most frequent manifestation. In conclusion, a relatively large proportion of the patients reported persisting symptoms that seem to be related to the symptom burden and to the atopy. Ninety days after the infection, most of the children had recovered, showing that long-term effects are not frequent. Limitations of the study include the single-center design and the lack of a control group.

During the COVID-19 pandemic, lung ultrasound (LUS) was widely used to assess SARS-CoV-2 infection. To date, there are patients with persistence of symptoms after acute infection. Therefore, it may be useful to have an objective tool to follow these patients. The aim of our study was to evaluate the presence of LUS artifacts after SARS-CoV-2 infection in children and to analyze the associations between time elapsed since infection and symptomatology during acute infection. We conducted an observational study, enrolling 607 children infected with SARS-CoV-2 in the previous twelve months. All patients performed a LUS and medical history of demographic and clinical data. We observed irregular pleural lines in 27.5%, B-lines in 16.9%, and subpleural consolidations in 8.6% of the cases. These artifacts were more frequently observed in the lower lobe projections. We have observed that the frequency of artifacts decreases with increasing time since infection. In symptomatic patients during COVID infection, B-lines (p = 0.02) were more frequently found. In our sample, some children, even after months of acute infection, have ultrasound artifacts and showed an improvement with the passage of time from the acute episode. Our study provides additional evidence about LUS in children with previous COVID-19 as a support to follow these patients in the months following the infection.
RESUMO
BACKGROUND: Bronchiolitis is the most frequent cause of hospitalization in infants younger than 1 year of age. We sought to evaluate the correlation between lymphocyte count and clinical manifestation in infants hospitalized with bronchiolitis. MATERIALS AND METHODS: We performed a retrospective cohort study evaluating 1297 children hospitalized for bronchiolitis from 2004 to 2019. A nasal washing was tested for 14 respiratory viruses by PCR. A clinical severity score, ranging 0-8, was assigned at hospital admission. History and clinical course were recorded for each infant. Patients were divided in 3 groups according to lymphocyte count tertiles. Parents of enrolled patients have been phoned annually over 5 years to evaluate respiratory sequelae. RESULTS: A total of 433 children had 2914.2 ± 745.5/mm3 lymphocytes (Group 1), 432 had 4897.6 ± 561.5/mm3 lymphocytes (Group 2) and 432 had 7884 ± 1903.3/mm3 lymphocytes (Group 3). Group 1 patients were more frequently infected by RSV and presented with fever, a worse clinical severity score. They more frequently needed oxygen supplementation, underwent a prolonged hospitalization needed to be admitted to pediatric intensive care unit. Finally, they had more frequently a family history of eczema, wheezing and asthma. We found no differences between lymphocytes count and respiratory sequelae (at least two episodes of wheezing per year). CONCLUSIONS: Infants with low lymphocyte count are more likely to have a worse clinical course of bronchiolitis.

RESUMO
Lung ultrasound has become increasingly used in both adult and pediatric populations, allowing the rapid evaluation of many lung and pleura diseases. This popularity is due to several advantages of the method such as the low cost, rapidity, lack of ionizing radiation, availability of bedside and repeatability of the method. These features are even more important after the outbreak of the SARS-CoV-2 pandemic, given the possibility of recognizing through ultrasound the signs of interstitial lung syndrome typical of pneumonia caused by the virus. The purpose of this paper is to review the available evidence of lung ultrasound (LUS) in children and its main applications in pediatric diseases.
RESUMO
On March 11, 2020, the World Health Organization (WHO) declared the pandemic because of a novel coronavirus, called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In January 2020, the first transmission to healthcare workers (HCWs) was described. SARS-CoV-2 is transmitted between people because of contact, droplets, and airborne. Airborne transmission is caused by aerosols that remain infectious when suspended in air over long distances and time. In the clinical setting, airborne transmission may occur during aerosol generating procedures like flexible bronchoscopy. To date, although the role of children in the transmission of SARS-CoV-2 is not clear the execution of bronchoscopy is associated with a considerably increased risk of SARS-CoV-2 transmission to HCWs. The aim of this overview is to summarize available recommendations and to apply them to pediatric bronchoscopy. We performed systematic literature searches using the MEDLINE (accessed via PubMed) and Scopus databases. We reviewed major recommendations and position statements published at the moment by the American Association for Bronchology and Interventional Pulmonology, WHO, European Center for Disease Prevention and Control and expert groups on the management of patients with COVID-19 to limit transmission among HCWs. To date there is a lack of recommendations for safe bronchoscopy during the pandemic period. The main indications concern adults and little has been said about children. We have summarized available recommendations and we have applied them to pediatric bronchoscopy.

BACKGROUND: Bronchiolitis is the most common acute viral infection of the lower respiratory tract in infants. Clinical severity is associated with different risk factors; however, no clinical, laboratory, or radiological findings are able to predict the course of the disease in full-term infants. Lung ultrasound (LUS) is a valid technique for the diagnosis and evaluation of pediatric respiratory diseases. AIMS: The aim of our study was to correlate an LUS score with a clinical score, to describe lung ultrasound findings in cases and controls, and to compare LUS findings with chest X-ray (CXR) in infants hospitalized with bronchiolitis. METHODS: We conducted a single-center, longitudinal, prospective study on 92 infants. Sixty-three out of 92 infants were hospitalized for acute bronchiolitis (cases) and twenty-nine out of 92 for diseases not involving the respiratory system (controls). All patients with bronchiolitis underwent a clinical evaluation with the assignment of a clinical severity score and performed lung ultrasound with the assignment of an LUS score. Twenty-three out of 63 infants with bronchiolitis underwent also a CXR for clinical indications. Control infants performed only LUS. RESULTS: In infants with bronchiolitis LUS score showed a positive correlation with the clinical score (r = .62, p < .001) and the length of hospitalization (r = .42; p < .001). The need of oxygen therapy was more frequent in the patients with higher LUS score (p < .001). LUS findings observed in the cases were the presence of B-lines, subpleural consolidations, and abnormalities of the pleural line. No LUS alterations were observed in the controls. In patients who performed LUS and CXR, we found a correlation between the presence of abnormalities of the pleural line with LUS and the presence of air trapping with CXR (r = .55; p = .007).

Pneumonia is an important cause of morbidity and mortality in children. We described viral aetiologies, with particular interest in detecting SARS-CoV-2, in hospitalized pneumonia children. Human rhinovirus was the most frequently detected agent. No children tested positive for SARS-CoV-2. Our findings suggest that SARS-CoV-2 infection is rare in children and it was not circulating in Rome before COVID-19 outbreak.
