Abstract
BACKGROUND Respiratory syncytial virus (RSV) is a widespread respiratory pathogen, and RSV-related acute lower respiratory tract infections are the most common cause of respiratory hospitalization in children <2 years of age. Over the last 2 decades, a number of severity scores have been proposed to quantify disease severity for RSV in children, yet there remains no overall consensus on the most clinically useful score. METHODS We conducted a systematic review of English-language publications in peer-reviewed journals published since January 2000 assessing the validity of severity scores for children (≤24 months of age) with RSV and/or bronchiolitis, and identified the most promising scores. For included articles, (1) validity data were extracted, (2) quality of reporting was assessed using the Transparent Reporting of a multivariable prediction model for Individual Prognosis Or Diagnosis checklist (TRIPOD), and (3) quality was assessed using the Prediction Model Risk Of Bias Assessment Tool (PROBAST). To guide the assessment of the validity data, standardized cutoffs were employed, and an explicit definition of what we required to determine a score was sufficiently validated. RESULTS Our searches identified 8541 results, of which 1779 were excluded as duplicates. After title and abstract screening, 6670 references were excluded. Following full-text screening and snowballing, 32 articles, including 31 scores, were included. The most frequently assessed scores were the modified Tal score and the Wang Bronchiolitis Severity Score; none of the scores were found to be sufficiently validated according to our definition. The reporting and/or design of all the included studies was poor. The best validated score was the Bronchiolitis Score of Sant Joan de Déu, and a number of other promising scores were identified. CONCLUSIONS No scores were found to be sufficiently validated. Further work is warranted to validate the existing scores, ideally in much larger datasets.

Abstract
OBJECTIVES Management of mechanically ventilated patients with bronchiolitis is not standardized and duration of mechanical ventilation has been shown to vary widely between centers. The aim of this study was to examine practice in a large number of U.K. PICUs with a view to identify if early management choices relating to fluid prescription, sedative agent use, and endotracheal tube (ETT) placement were associated with differences in duration of invasive mechanical ventilation (IMV). DESIGN Retrospective multicenter cohort study. Primary outcome was duration of IMV. A hierarchical gamma generalized linear model was used to test for associations between practice variables (sedative and neuromuscular blocking agents, route of endotracheal intubation at 24 hr and fluid balance at 48 hr) and duration of IMV after adjustment for known confounders. SETTING Thirteen U.K. PICUs. Duration of 2 months between November and December 2019. PATIENTS Three hundred fifty infants receiving IMV for bronchiolitis. Excluded were patients receiving long-term ventilation, extracorporeal life support, or who died before separation from IMV. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS After adjustment for confounders, several variables were associated with an increase in the geometric mean duration of IMV (expressed as a percentage) including: nasal ETT use, 16% (95% CI, 1-32%); neuromuscular blockade use, 39% (95% CI, 21-61%); and fluid balance at 48 hr, 13% per 100 mL/kg positive fluid balance (95% CI, -1% to 28%). The association of sedative use varied with class of agent. The use of an alpha-2 agonist alone was associated with a reduction in duration of IMV by 19% in relation to no sedative agent (95% CI, -31 to -5%), whereas benzodiazepine uses alone or with alpha-2 agonist in combination were similar to using neither agent. CONCLUSIONS Early management strategies for bronchiolitis were associated with the duration of IMV across U.K. centers after adjustment for confounders. Future work should prospectively assess the impact of fluid restriction, route of endotracheal intubation, and alpha-2 agonist use on duration of IMV in infants with bronchiolitis, with the aim of reducing seasonal bed pressure.

Abstract
OBJECTIVE Management guidelines for bronchiolitis advocate for supportive care and exclude those with high-risk conditions. We aim to describe and compare the management of standard-risk and high-risk patients with bronchiolitis. METHODS This retrospective study examined patients <2 years of age admitted to the general pediatric ward with an International Classification of Diseases, 10th Revision discharge diagnosis code of bronchiolitis or viral syndrome with evidence of lower respiratory tract involvement. Patients were defined as either standard- or high-risk on the basis of previously published criteria. The frequencies of diagnostic and therapeutic interventions were compared. RESULTS We included 265 patients in this study (122 standard-risk [46.0%], 143 high-risk [54.0%]). Increased bronchodilator use was observed in the standard-risk group (any albuterol dosing, standard-risk 65.6%, high-risk 44.1%, P = .003). Increased steroid use was observed in the standard-risk group (any steroid dosing, standard-risk 19.7%, high-risk 14.7%, P = .018). Multiple logistic regression revealed >3 doses of albuterol, hypertonic saline, and chest physiotherapy use to be associated with rapid response team activation (odds ratio [OR] >3 doses albuterol: 8.36 [95% confidence interval (CI): 1.99-35.10], P = .048; OR >3 doses hypertonic saline: 13.94 [95% CI: 4.32-44.92], P = .001); OR percussion and postural drainage: 5.06 [95% CI: 1.88-13.63], P = .017). CONCLUSIONS A varied approach to the management of bronchiolitis in both standard-risk and high-risk children occurred institutionally. Bronchodilators and steroids continue to be used frequently despite practice recommendations and regardless of risk status. More research is needed on management strategies in patients at high-risk for severe disease.

Abstract
INTRODUCTION Viral bronchiolitis is a common lower respiratory tract infection in infants. Environmental and genetic factors can favor respiratory tract infections. AIM The aim of this study is to analyze risk factors for bronchiolitis and to investigate the predisposing factors for developing transient wheezing and asthma through a 6-year follow-up after hospitalization for bronchiolitis compared with a group of healthy controls that belonged to Piccolipiù cohort, who never had bronchiolitis. METHODS We enrolled 645 infants hospitalized with bronchiolitis. A structured questionnaire was used to obtain demographic and clinical data. At 6 years of age, 370 cases and 183 controls were investigated for the presence of asthma by the structured questionnaire, for prick test and for spirometry, and were classified to asthmatic, transient wheezing, and no wheezing/no asthma. RESULTS Breastfeeding was an independent protective factor (odds ratio [OR]: 0.3, 95% confidence interval [95% CI]: 0.2-0.4, p < 0.001) and tobacco smoke was a risk factor for the development of bronchiolitis (OR: 2.1, 95% CI: 1.4-3.1, p < 0.001). Analyzing follow-up, bronchiolitis increased the risk of developing transient wheezing by 12.9 (95% CI: 6.3-26.1, p < 0.001) and of developing asthma by 4.6 (95% CI: 1.9-10.7, p < 0.001). A positive family history of atopy increased the risk of developing asthma by 3.1 (95% CI: 1.4-6.7, p = 0.005). Asthmatic patients had a lower % FEV1, a lower % flow-volume curve (FVC), and a lower FEV1/FVC value, and they had more frequently positive skin prick test. CONCLUSION Bronchiolitis is influenced by environmental factors: tobacco smoke increases its risk and breastfeeding is a protective factor. At the end of 6 years of follow-up, bronchiolitis is a significant risk factor to have pre-school wheezing and asthma.

Abstract
BACKGROUND Human metapneumovirus (hMPV) has been associated with upper and lower respiratory tract infections (LRTI) in children and adults. This systematic review evaluated the epidemiology of hMPV-associated LRTI, including severe acute respiratory infection (SARI) hospitalization or clinically diagnosed severe pneumonia, in African children under 5 years of age. METHODS We searched Science Direct, PubMed, Cochrane Central, Scopus, and WHO regional databases using the terms "("Human metapneumovirus" AND "Africa") OR ("hMPV" AND "Africa")" up to September 17, 2020. Other sources included ClinicalTrials.gov to obtain unpublished data. Studies were included if children were less than 5 years of age and hospitalized with hMPV-associated LRTI, SARI or if clinically diagnosed with severe pneumonia in the community. The main outcomes were prevalence of hMPV identified among children with hospitalized LRTI or SARI. We further calculated odds ratios for hMPV in cases with LRTI compared with non-LRTI controls. Pooled results were calculated using a random-effects model. RESULTS Thirty studies were eligible for inclusion in the review. The prevalence of hMPV-LRTI/SARI among hospitalized and severe pneumonia cases was 4.7% [95% confidence interval (CI): 3.9-5.6, I2 = 95.0]. The case-control studies indicated that hMPV was 2.0-fold (95% CI: 0.9-4.4) more likely to be identified in LRTI cases (10.3%) than controls (6.0%). Three of 5 studies reported hMPV-associated LRTI case fatality risk, with a pooled estimate of 1.3% (95% CI: 0.3-2.9; I2 = 49). CONCLUSIONS hMPV was associated with approximately 5% of LRTI/SARI hospitalizations or severe pneumonia cases in Africa.
