RESUMEN
OBJECTIVE: To systematically assess and quantitatively synthesize the literature regarding the association of consumption of non-nutritive sweeteners (NNS) during childhood with negative metabolic health outcomes. STUDY DESIGN: Following the PRISMA guidelines, published literature was systematically reviewed. Eligible studies (N = 13) were identified through the screening of over 2500 publications. Random-effects meta-analyses were conducted on the association of NNS consumption with body mass index (BMI) increase. Sensitivity and subgroup analyses by sex were also undertaken. RESULTS: Consumption of NNS during childhood and adolescence was associated with an increase in BMI (OR 1.15, 95% CI 1.06-1.25); the OR was similar in sensitivity analyses. The associations were positive but marginally significant in subanalyses by sex. The qualitative assessment of existing literature showed nonsignificant associations with other components of metabolic disease, such as waist circumference, fat mass accumulation, and type 2 diabetes. CONCLUSIONS: Systematic assessment of observational studies showed no association of NNS intake during childhood with fat mass accumulation and waist circumference and a small, but statistically significant association with BMI increase. Inherent methodological weaknesses of to-date published investigations, including mainly underpowered size to explore the hypothesis, call for more research.

INTRODUCTION: Clinical recommendations for childhood asthma are often based on data extrapolated from studies conducted in adults, despite significant differences in mechanisms and response to treatments. The Paediatric Asthma in Real Life (PeARL) Think Tank aspires to develop recommendations based on the best available evidence from studies in children. An overview of systematic reviews (SRs) on paediatric asthma maintenance management and an SR of treatments for acute asthma attacks in children, requiring an emergency presentation with/without hospital admission will be conducted. METHODS AND ANALYSIS: Standard methodology recommended by Cochrane will be followed. Maintenance pharmacotherapy of childhood asthma will be evaluated in an overview of SRs published after 2005 and including clinical trials or real-life studies. For evaluating pharmacotherapy of acute asthma attacks leading to an emergency presentation with/without hospital admission, we opted to conduct de novo synthesis in the absence of adequate up-to-date published SRs. For the SR of acute asthma pharmacotherapy, we will consider eligible SRs, clinical trials or real-life studies without time restrictions. Our evidence updates will be based on broad searches of Pubmed/Medline and the Cochrane Library. We will use A MeaSurement Tool to Assess systematic Reviews, V.2, Cochrane risk of bias 2 and REal Life EVidence AssessmeNt Tool to evaluate the methodological quality of SRs, controlled clinical trials and real-life studies, respectively.Next, we will further assess interventions for acute severe asthma attacks with positive clinical results in meta-analyses. We will include both controlled clinical trials and observational studies and will assess their quality using the previously mentioned tools. We will employ random effect models for conducting meta-analyses, and Grading of Recommendations Assessment, Development and Evaluation methodology to assess certainty in the body of evidence. ETHICS AND DISSEMINATION: Ethics approval is not required for SRs. Our findings will be published in peer reviewed journals and will inform clinical recommendations being developed by the PeARL Think Tank. PROSPERO REGISTRATION NUMBERS: CRD42020132990, CRD42020171624.

We report the case of an 11-year-old preadolescent girl presenting with prolonged fever, lymphadenitis, nonpurulent conjunctivitis, a generalized maculopapular rash, erythematous lips and edema of hands/feet. Although major diagnostic criteria for Kawasaki disease were met, local epidemiologic data suggested a possible vector-borne etiology. Treatment with doxycycline was initiated, and defervescence occurred. Laboratory investigation confirmed the diagnosis of Rickettsia typhi infection.
