Salbutamol safety in children under 2 years of age with acute wheezing: a meta-analysis of randomised controlled trials.

OBJECTIVE: To evaluate the safety of short-term use of inhaled salbutamol in children under 2 years of age with acute wheezing. DATA SOURCES: Electronic databases (PubMed, Trip, MEDLINE) and the Cochrane Library were searched for studies published up to October 2022. STUDY SELECTION: The search was restricted to randomised controlled trials published in English regarding the safety of inhaled salbutamol in wheezing children under the age of 2. DATA EXTRACTION AND SYNTHESIS: The literature search strategy yielded 3532 references. The meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. MAIN OUTCOMES AND MEASURES: The incidence of adverse reactions associated with inhaled salbutamol administration compared with placebo. RESULTS: A total of 24 records were included. In 7 studies involving 597 patients, inhaled salbutamol was compared with controls and no statistically significant difference in the incidence of adverse drug reactions was found between the two groups (OR 2.12, 95% CI 0.69 to 6.51; p=0.19). Salbutamol administration via nebulisation was associated with an increased incidence of adverse reactions (OR 6.76, 95% CI 2.01 to 22.71; p=0.002). None of the studies reported severe cardiac side effects that necessitated withdrawal from the study following salbutamol administration. Only one study reported a significant non-cardiac side effect (severe tremulousness) that necessitated withdrawal from therapy. CONCLUSIONS: Inhaled salbutamol can be safely used in children under 2 years of age with acute wheeze with the administration via a metered-dose inhaler being potentially safer than a nebulised formulation. Neither of the formulations was associated with severe adverse effects.

National survey conducted among Italian pediatricians examining the therapeutic management of croup.

OBJECTIVES: Practice-to-recommendations gaps exist in croup management and have not been critically investigated. This study examined the therapeutic management of croup among a national sample of Italian pediatric providers. METHODS: A survey was administered online to a sample of primary care and hospital-based pediatricians. Demographic data, perception regarding disease severity, treatment and knowledge of croup, choices of croup treatment medications, and knowledge of and adherence to treatment recommendations were compared between hospital and primary care pediatricians. Oral corticosteroids alone, oral corticosteroids with or without nebulized epinephrine and nebulized epinephrine plus oral or inhaled corticosteroids were considered the correct management in mild, moderate and severe croup, respectively. The determinants for correct management were examined using multivariate logistic regression analysis. RESULTS: Six hundred forty-nine pediatricians answered at least 50% of the survey questions and were included in the analysis. Providers reported extensive use of inhaled corticosteroids for mild and moderate croup. Recommended treatment for mild, moderate and severe croup was administered in 46/647 (7.1%), 181/645 (28.0%) and 263/643 (40.9%) participants, respectively. Provider's age and knowledge of Westley Croup Score were significant predictors for correct management of mild croup. Being a hospital pediatrician and perception of croup as a clinically relevant condition were significant for moderate croup. CONCLUSIONS: Significant differences exist between recommended guidelines and clinical practice in croup management. This study suggests wide variability in both the treatment of croup and clinical decision making strategies among hospital and primary care pediatricians. Addressing this issue could lead to noteworthy clinical and economic benefits.

Pediatric non-Hodgkin lymphoma as a rare cause of spinal cord injury: When lymphoma hides in the canal.

Key Clinical Message: Spinal cord compression from non-Hodgkin lymphoma (NHL) should be considered as a potential diagnosis in cases of acute signs of myelopathy in pediatric patients. Abstract: Spinal cord compression in pediatric non-Hodgkin lymphoma (NHL) is a rare presentation with potential diagnostic challenges. We report on two pediatric patients with NHL who exhibited myelopathy signs as initial presentation. Considering NHL as a differential diagnosis in pediatric patients presenting with spinal cord compression is crucial for optimizing the outcome of these patients.

Letermovir for Cytomegalovirus infection in pediatric patients undergoing allogenic hematopoietic stem cell transplantation: a real-life study by the Infectious Diseases Working Group of Italian Association of Pediatric Hematology-Oncology (AIEOP).

Letermovir prophylaxis revolutionized the approach to Cytomegalovirus infection in adult hematopoietic stem cell transplant (HCT), while data in pediatric setting are still lacking. We retrospectively analyzed 87 HCT children transplanted in 11 AIEOP centers receiving letermovir as off-label indication between January 2020 and November 2022. Letermovir was used as primary, secondary prophylaxis or CMV treatment in 39, 26 and 22 cases, respectively; no discontinuation due to toxicity was reported. Median duration was 100 days (14-256) for primary and 96 days (8-271) for secondary prophylaxis, respectively. None of the patients experienced CMV-clinically significant reactivation during Letermovir primary prophylaxis; one patient developed breakthrough infection during secondary prophylaxis, and 10 and 1 patient experienced asymptomatic CMV-reactivation and CMV-primary infection after drug discontinuation, respectively. Median duration of letermovir in CMV treatment was 40 days (7-134), with 4/22 patients suffering CMV-pneumonia, with an overall response rate of 86.4%. With a median follow-up of 10.7 months (8.2-11.8), estimated 1-year overall survival was 86%; no CMV-related deaths were reported in prophylaxis groups. This is the largest report on Letermovir use in pediatric HCT; real-life data confirm an excellent toxicity profile, with high efficacy as CMV prophylaxis; results in CMV-infection treatment should be investigated in larger, prospective trials.

SARS-CoV-2 Infection in the Pediatric Oncology Population: The Definitive Comprehensive Report of the Infectious Diseases Working Group of AIEOP.

OBJECTIVE: The objective of this study was to assess the clinical impact and outcome of the SARS-CoV-2 infection on children with cancer or those who received a hematopoietic stem cell transplantation. METHODS: AIEOP (Italian Association of Pediatric Hematology and Oncology) performed a nationwide multicenter observational cohort study, including consecutive patients between April 2020 and November 2022. RESULTS: Twenty-five Italian centers participated and 455 patients were enrolled. We reported a significant increasing trend of symptomatic cases over the years, while the number of nonmild infections remained stable. Early infection after oncologic diagnosis (<60 days) and severe neutropenia were identified as independent risk factors for developing moderate, severe, or critical infections. The percentage of patients who were asymptomatic and mildly symptomatic and who stopped chemotherapy reduced over the years of the pandemic. Nine patients died, but no death was attributed to SARS-CoV-2 infection. CONCLUSIONS: SARS-CoV-2 infection presented a self-limiting benign course in the Italian pediatric oncohematology population during the pandemic, and its main consequence has been the discontinuation of cancer-directed therapies. The rate of patients who were asymptomatic and stopped chemotherapy reduced over the years, suggesting that the continuation of chemotherapy is a feasible option.

Gut microbiota diversity before allogeneic hematopoietic stem cell transplantation as a predictor of mortality in children.

The correlation existing between gut microbiota diversity and survival after allogeneic hematopoietic stem cell transplantation (allo-HSCT) has so far been studied in adults. Pediatric studies question whether this association applies to children as well. Stool samples from a multicenter cohort of 90 pediatric allo-HSCT recipients were analyzed using 16S ribosomal RNA amplicon sequencing to profile the gut microbiota and estimate diversity with the Shannon index. A global-to-local networking approach was used to characterize the ecological structure of the gut microbiota. Patients were stratified into higher- and lower-diversity groups at 2 time points: before transplantation and at neutrophil engraftment. The higher-diversity group before transplantation exhibited a higher probability of overall survival (88.9% ± 5.7% standard error [SE] vs 62.7% ± 8.2% SE; P = .011) and lower incidence of grade 2 to 4 and grade 3 to 4 acute graft-versus-host disease (aGVHD). No significant difference in relapse-free survival was observed between the 2 groups (80.0% ± 6.0% SE vs 55.4% ± 10.8% SE; P = .091). The higher-diversity group was characterized by higher relative abundances of potentially health-related microbial families, such as Ruminococcaceae and Oscillospiraceae. In contrast, the lower-diversity group showed an overabundance of Enterococcaceae and Enterobacteriaceae. Network analysis detected short-chain fatty acid producers, such as Blautia, Faecalibacterium, Roseburia, and Bacteroides, as keystones in the higher-diversity group. Enterococcus, Escherichia-Shigella, and Enterobacter were instead the keystones detected in the lower-diversity group. These results indicate that gut microbiota diversity and composition before transplantation correlate with survival and with the likelihood of developing aGVHD.

Anti-Inflammatory and Immunomodulatory Effect of High-Dose Immunoglobulins in Children: From Approved Indications to Off-Label Use.

BACKGROUND: The large-scale utilization of immunoglobulins in patients with inborn errors of immunity (IEIs) since 1952 prompted the discovery of their key role at high doses as immunomodulatory and anti-inflammatory therapy, in the treatment of IEI-related immune dysregulation disorders, according to labelled and off-label indications. Recent years have been dominated by a progressive imbalance between the gradual but constant increase in the use of immunoglobulins and their availability, exacerbated by the SARS-CoV-2 pandemic. OBJECTIVES: To provide pragmatic indications for a need-based application of high-dose immunoglobulins in the pediatric context. SOURCES: A literature search was performed using PubMed, from inception until 1st August 2023, including the following keywords: anti-inflammatory; children; high dose gammaglobulin; high dose immunoglobulin; immune dysregulation; immunomodulation; immunomodulatory; inflammation; intravenous gammaglobulin; intravenous immunoglobulin; off-label; pediatric; subcutaneous gammaglobulin; subcutaneous immunoglobulin. All article types were considered. IMPLICATIONS: In the light of the current imbalance between gammaglobulins' demand and availability, this review advocates the urgency of a more conscious utilization of this medical product, giving indications about benefits, risks, cost-effectiveness, and administration routes of high-dose immunoglobulins in children with hematologic, neurologic, and inflammatory immune dysregulation disorders, prompting further research towards a responsible employment of gammaglobulins and improving the therapeutical decisional process.

Gut, oral, and nasopharyngeal microbiota dynamics in the clinical course of hospitalized infants with respiratory syncytial virus bronchiolitis.

Introduction: Respiratory syncytial virus (RSV) is the most common cause of bronchiolitis and hospitalization in infants worldwide. The nasopharyngeal microbiota has been suggested to play a role in influencing the clinical course of RSV bronchiolitis, and some evidence has been provided regarding oral and gut microbiota. However, most studies have focused on a single timepoint, and none has investigated all three ecosystems at once. Methods: Here, we simultaneously reconstructed the gut, oral and nasopharyngeal microbiota dynamics of 19 infants with RSV bronchiolitis in relation to the duration of hospitalization (more or less than 5 days). Fecal samples, oral swabs, and nasopharyngeal aspirates were collected at three timepoints (emergency room admission, discharge and six-month follow-up) and profiled by 16S rRNA amplicon sequencing. Results: Interestingly, all ecosystems underwent rearrangements over time but with distinct configurations depending on the clinical course of bronchiolitis. In particular, infants hospitalized for longer showed early and persistent signatures of unhealthy microbiota in all ecosystems, i.e., an increased representation of pathobionts and a depletion of typical age-predicted commensals. Discussion: Monitoring infant microbiota during RSV bronchiolitis and promptly reversing any dysbiotic features could be important for prognosis and long-term health.

Antibiotic Prescribing for Lower Respiratory Tract Infections and Community-Acquired Pneumonia: An Italian Pediatric Emergency Department's Real-Life Experience.

BACKGROUND: Lower respiratory tract infections (LRTIs) and community-acquired pneumonia (CAP) are among the most frequent reasons for referrals to the pediatric emergency department (PED). The aim of this study is to describe the management of antibiotic prescription in febrile children with LRTI or CAP admitted to a third-level PED and to investigate the different variables that can guide physicians in this decision-making. METHODS: This is an observational, retrospective, monocentric study including patients < 14 years old who were presented to the PED for a febrile LRTI or CAP during the first six months of the year 2017. Demographic and clinical data, PED examinations, recommended therapy, and discharge modality were considered. Two multivariate logistic regression analyses were performed on patients with complete profiles to investigate the impact of demographic, laboratory, and clinical variables on antibiotic prescription and hospital admission. RESULTS: This study included 584 patients with LRTI (n = 368) or CAP (n = 216). One hundred and sixty-eight individuals (28.7%) were admitted to the hospital. Lower age, higher heart rate, and lower SpO2 were associated with an increased risk of hospitalization. Antibiotics were prescribed to 495 (84.8%) patients. According to the multivariate logistic regression, the diagnosis and duration of fever were substantially linked with antibiotic prescription. CONCLUSIONS: The present study reports real-life data about our PED experience. A high rate of antibiotic prescription was noted. In the future, it is necessary to improve antibiotic stewardship programs to increase clinical adherence to guidelines.

Multicenter Observational Retrospective Study on Febrile Events in Patients with Acute Myeloid Leukemia Treated with Cpx-351 in "Real-Life": The SEIFEM Experience.

In the present study, we aimed to evaluate the absolute risk of infection in the real-life setting of AML patients treated with CPX-351. The study included all patients with AML from 30 Italian hematology centers of the SEIFEM group who received CPX-351 from July 2018 to June 2021. There were 200 patients included. Overall, 336 CPX-351 courses were counted: all 200 patients received the first induction cycle, 18 patients (5%) received a second CPX-351 induction, while 86 patients (26%) proceeded with the first CPX-351 consolidation cycle, and 32 patients (10%) received a second CPX-351 consolidation. A total of 249 febrile events were recorded: 193 during the first or second induction, and 56 after the first or second consolidation. After the diagnostic work-up, 92 events (37%) were classified as febrile neutropenia of unknown origin (FUO), 118 (47%) were classifiable as microbiologically documented infections, and 39 (17%) were classifiable as clinically documented infections. The overall 30-day mortality rate was 14% (28/200). The attributable mortality-infection rate was 6% (15/249). A lack of response to the CPX-351 treatment was the only factor significantly associated with mortality in the multivariate analysis [p-value: 0.004, OR 0.05, 95% CI 0.01-0.39]. Our study confirms the good safety profile of CPX-351 in a real-life setting, with an incidence of infectious complications comparable to that of the pivotal studies; despite prolonged neutropenia, the incidence of fungal infections was low, as was infection-related mortality.

Exposure to outdoor air pollution and risk of hospitalization for bronchiolitis in an urban environment: A 9-year observational study.

BACKGROUND: Outdoor air pollution is supposed to influence the course of bronchiolitis, but the evidence is limited. The present study aimed at evaluating the role of outdoor air pollutants on hospitalization for bronchiolitis. METHODS: Infants aged ≤12 months referred for bronchiolitis to our Pediatric Emergency Department in Bologna, Italy, from 1 October 2011 to 16 March 2020 (nine epidemic seasons) were retrospectively included. Daily concentrations of benzene (C6 H6 ), nitrogen dioxide (NO2 ), particulate matter ≤2.5 µm (PM2.5 ), and ≤10 µm (PM10 ), and the mean values of individual patient exposure in the week and the 4 weeks before hospital access were calculated. The association between air pollutants exposure and hospitalization was evaluated through logistic regression analysis. RESULTS: A total of 2902 patients were enrolled (59.9% males; 38.7% hospitalized). Exposure to PM2.5 in the 4 weeks preceding bronchiolitis was identified as the main parameter significantly driving the risk of hospitalization (odds ratio [95% confidence interval]: 1.055 [1.010-1.102]). After stratifying by season, higher values of other outdoor air pollutants were found to significantly affect hospitalization: 4-week exposure to C6 H6 (Season 2011-2012, 4.090 [1.184-14.130]) and PM2.5 (Season 2017-2018, 1.282 [1.032-1.593]), and 1-week exposure to C6 H6 (Season 2012-2013, 6.193 [1.552-24.710]), NO2 (Season 2013-2014, 1.064 [1.009-1.122]), PM2.5 (Season 2013-2014, 1.080 [1.023-1.141]), and PM10 (Season 2018-2019, 1.102 [0.991-1.225]). CONCLUSION: High levels of PM2.5 , C6 H6 , NO2 , and PM10 may increase the risk of hospitalization in children affected by bronchiolitis. Open-air exposure of infants during rush hours and in the most polluted areas should be avoided.

Respiratory Syncytial Virus-Load Kinetics and Clinical Course of Acute Bronchiolitis in Hospitalized Infants: Interim Results and Review of the Literature.

Respiratory Syncytial Virus (RSV) bronchiolitis is the leading cause of hospitalization in infants. The role of RSV load in disease severity is still debated. We present the interim results of a prospective monocentric study enrolling previously healthy infants hospitalized for RSV bronchiolitis, collecting nasopharyngeal aspirates every 48 h from admission to discharge, and evaluating RSV load dynamics in relation to clinical outcome measures of bronchiolitis severity, including: need, type and duration of oxygen therapy, length of hospitalization, and the bronchiolitis clinical score calculated at admission. The results showed that the highest viral replication occurs within the first 48 hours after admission, with a significant decrease at subsequent time points (p < 0.0001). Moreover, higher RSV-RNA values were associated with the need for oxygen therapy (p = 0.03), particularly high-flow nasal cannula type (p = 0.04), and longer duration of respiratory support (p = 0.04). Finally, higher RSV load values were correlated with lower white blood cells, especially lymphocyte counts and C-reactive protein levels (p = 0.03, p = 0.04, and p = 0.01, respectively), as well as with patients of a younger age (p = 0.02). These data suggest that RSV may actively contribute to the clinical severity of bronchiolitis, together with other potential non-viral factors.

The role of presepsin in pediatric patients with oncological and hematological diseases experiencing febrile neutropenia.

Febrile neutropenia (FN) represents one of the main complications of pediatric patients with oncological and hematological diseases. In these patients, it is crucial to identify bacterial infections. The aim of this study is to evaluate presepsin as an early biomarker of bacterial infections during FN. We compared patients with oncological and hematological diseases and a 2:1 age-matched healthy control group. In the FN group, we evaluated 4 biomarkers, namely, C reactive protein (CRP), procalcitonin (PCT), interleukin 6 (IL6) and presepsin at the onset of fever (T0) and 48 h after T0 (T1). In the control group, we only evaluated presepsin. We enrolled a total of 41 children with oncological and hematological diseases disease experiencing 50 FN episodes and 100 healthy patients in the control group. In patients with FN, we found that presepsin was significantly higher than in the control group (p < 0.001). However, in the FN group, we did not find a statistically significant difference between patients with and without bacteremia (p = 0.989 at T0, p = 0.619 at T1). Presepsin values at T1 were higher in patients experiencing an unfavorable outcome (p = 0.025). This study shows that presepsin increases in neutropenic patients, but it only revealed useful in predicting an unfavorable outcome 48 h from the onset of fever.

Different Pediatric Acute Care Settings Influence Bronchiolitis Management: A 10-Year Retrospective Study.

Bronchiolitis is the main cause of hospitalization in infants. Diagnosis is clinical, and treatment is based on hydration and oxygen therapy. Nevertheless, unnecessary diagnostic tests and pharmacological treatments are still very common. This retrospective study aimed to evaluate whether the setting of bronchiolitis care influences diagnostic and therapeutic choices. The management of 3201 infants, referred to our Italian Tertiary Care Center for bronchiolitis between 2010 and 2020, was analyzed by comparing children discharged from the pediatric emergency department (PEDd group) undergoing short-stay observation (SSO group) and hospitalization. Antibiotic use in PEDd, SSO, and ward was 59.3% vs. 51.6% vs. 49.7%, respectively (p < 0.001); inhaled salbutamol was mainly administered in PEDd and during SSO (76.1% and 82.2% vs. 38.3% in ward; p < 0.001); the use of corticosteroids was higher during SSO and hospitalization (59.6% and 49.1% vs. 39.0% in PEDd; p < 0.001); inhaled adrenaline was administered mostly in hospitalized infants (53.5% vs. 2.5% in SSO and 0.2% in PEDd; p < 0.001); chest X-ray use in PEDd, SSO, and ward was 30.3% vs. 49.0% vs. 70.5%, respectively (p < 0.001). In a multivariate analysis, undergoing SSO was found to be an independent risk factor for the use of systemic corticosteroid and salbutamol; being discharged at home was found to be a risk factor for antibiotic prescription; undergoing SSO and hospitalization resulted as independent risk factors for the use of CXR. Our study highlights that different pediatric acute care settings could influence the management of bronchiolitis. Factors influencing practice may include a high turnover of PED medical staff, personal reassurance, and parental pressure.

The emerging role of nutritional support in the supportive care of pediatric patients undergoing hematopoietic stem cell transplantation.

Allogeneic Hematopoietic Stem Cell Transplantation (allo-HSCT) represents a potentially curative strategy for many oncological, hematological, metabolic, and immunological diseases in children. The continuous effort in ameliorating supportive care represents one of the cornerstones in the improvement of outcome in these patients. Nowadays, more than ever nutritional support can be considered a key feature. Oral feeding in the early post-transplant period is severely impaired because of mucositis due to conditioning regimen, characterized by, mainly by vomiting, anorexia, and diarrhea. Gastrointestinal acute graft-versus-host-disease (GvHD), infections and associated treatments, and other medications, such as opioids and calcineurin inhibitors, have also been correlated with decreased oral intake. The consequent reduction in caloric intake combined with the catabolic effect of therapies and transplantation-related complications with consequent extended immobilization, results in a rapid deterioration of nutritional status, which is associated with decreased overall survival and higher complication rates during treatment. Thus, nutritional support during the early post-transplantation period becomes an essential and challenging issue for allo-HSCT recipients. In this context, the role of nutrition in the modulation of the intestinal flora is also emerging as a key player in the pathophysiology of the main complications of HSCT. The pediatric setting is characterized by less evidence, considering the challenge of addressing nutritional needs in this specific population, and many questions are still unanswered. Thus, we perform a narrative review regarding all aspects of nutritional support in pediatric allo-HSCT recipients, addressing the assessment of nutritional status, the relationship between nutritional status and clinical outcomes and the evaluation of the nutritional support, ranging from specific diets to artificial feeding.

Outdoor Air Pollution and Childhood Respiratory Disease: The Role of Oxidative Stress.

The leading mechanisms through which air pollutants exert their damaging effects are the promotion of oxidative stress, the induction of an inflammatory response, and the deregulation of the immune system by reducing its ability to limit infectious agents' spreading. This influence starts in the prenatal age and continues during childhood, the most susceptible period of life, due to a lower efficiency of oxidative damage detoxification, a higher metabolic and breathing rate, and enhanced oxygen consumption per unit of body mass. Air pollution is involved in acute disorders like asthma exacerbations and upper and lower respiratory infections, including bronchiolitis, tuberculosis, and pneumoniae. Pollutants can also contribute to the onset of chronic asthma, and they can lead to a deficit in lung function and growth, long-term respiratory damage, and eventually chronic respiratory illness. Air pollution abatement policies, applied in the last decades, are contributing to mitigating air quality issues, but more efforts should be encouraged to improve acute childhood respiratory disease with possible positive long-term effects on lung function. This narrative review aims to summarize the most recent studies on the links between air pollution and childhood respiratory illness.

Levofloxacin prophylaxis and parenteral nutrition have a detrimental effect on intestinal microbial networks in pediatric patients undergoing HSCT.

The gut microbiome (GM) has shown to influence hematopoietic stem cell transplantation (HSCT) outcome. Evidence on levofloxacin (LVX) prophylaxis usefulness before HSCT in pediatric patients is controversial and its impact on GM is poorly characterized. Post-HSCT parenteral nutrition (PN) is oftentimes the first-line nutritional support in the neutropenic phase, despite the emerging benefits of enteral nutrition (EN). In this exploratory work, we used a global-to-local networking approach to obtain a high-resolution longitudinal characterization of the GM in 30 pediatric HSCT patients receiving PN combined with LVX prophylaxis or PN alone or EN alone. By evaluating the network topology, we found that PN, especially preceded by LVX prophylaxis, resulted in a detrimental effect over the GM, with low modularity, poor cohesion, a shift in keystone species and the emergence of modules comprising several pathobionts, such as Klebsiella spp., [Ruminococcus] gnavus, Flavonifractor plautii and Enterococcus faecium. Our pilot findings on LVX prophylaxis and PN-related disruption of GM networks should be considered in patient management, to possibly facilitate prompt recovery/maintenance of a healthy and well-wired GM. However, the impact of LVX prophylaxis and nutritional support on short- to long-term post-HSCT clinical outcomes has yet to be elucidated.

Use of music therapy in pediatric oncology: an Italian AIEOP multicentric survey study in the era of COVID-19.

Music therapy (MT) is a complementary therapy offered to children, young adults, and their families in pediatric oncology and palliative care. We performed a survey to collect information about MT in pediatric oncology in Italy. The outbreak of COVID-19 unavoidably changed the scenario of MT, suggesting some considerations presented in this survey. 27/32 (84.4%) centers belonging to the Infections and Supportive Therapy Working Group of Association of Pediatric Hematology and Oncology (AEIOP) completed in 2 different time points (T1 and T2) an online survey on MT, before and after COVID-19 pandemia. Different kinds of music approach were used taking care of patients in 21/27 centers, while in 14/21 (66%), a specific project of MT conducted by a music therapist was present. In 6/14 centers, MT activities were delivered for < 3 h/week, in 3 centers for > 3 and < 10 h/week, and in the remaining 5 for > 3 h/week. MT sessions were in different areas, day hospital, or ward (patient rooms, operating rooms, waiting rooms), on an individual basis or by groups. Patients were invited to MT by psychologists, caring physician, or nurse, or on equipé decision. MT was evaluated with tools self-made by music therapist in 11/14 centers. After COVID-19, MT has been withdrawn in 3 centers, sessions in the waiting rooms were reduced, individual sessions were preferred, and enrollment by multidisciplinary teams increased. CONCLUSION: This survey represents the starting platform to compare and discuss different experience of MT in AIEOP centers, to implement MT in pediatric oncology for a more qualified assistance to patients, and to improve quality of care. WHAT IS KNOWN: • Music therapy in pediatric oncology and palliative care can be used for the management and prevention of various somatic and psychological symptoms of patients and often is provided to children together with their families. • In Italy the application of Music therapy in the AIEOP pediatric oncology centers is constantly increasing, but due to the outbreak of Covid-19 Pandemic, Italian pediatric oncology departments were obliged to adopt restrictive measures. WHAT IS NEW: • Although the majority of Centres did not abrogate MT interventions, judgment about limitation should be carefully taken since MT helps children and even more adolescents in their fight against cancer. • The best practice of Music therapy in pediatric oncology requires communication and collaboration among qualified music therapists and multidisciplinary care team, using a model of family-centered care that actively involves parents/ caregivers in assessment, treatment planning, and care delivery.
