    Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:
    Our study has several limitations, including the relatively low number of cases in each group, the lack of a comparison with asymptomatic or mildly symptomatic non-hospitalized children positive for SARS-CoV-2 and a longitudinal study of children with “classic” KD enrolled before the COVID-19 pandemic. All our cellular data were generated from frozen peripheral mononuclear cells, which does not allow a direct assessment of neutrophils. A parallel analysis of PMN (polymorphonuclear leukocytes) will be required. Endothelial and myocardiac cells are at least targets of the disease but may also contribute to the pathophysiology as described above. Also, additional data supporting gene expression findings will be necessary in future studies. Nevertheless, our study provides further in-depth molecular analysis of MIS-C with severe myocarditis. These severe forms were found to be associated with an excessive activation of the TNF-α, NF-κB signaling axis and poor response to type-I and type-II interferons in monocytes and DCs, secretion of cytokines promoting angiogenesis, chemotaxis and potential migration of activated myeloid cells and neutrophils in the myocardiac tissue. This may help to identify potential new clinical biomarkers and open new therapeutic strategies, including drugs targeting TNF-α or NF-κB pathways.

    About SciScore

    SciScore is an automated tool that is designed to assist expert reviewers by finding and presenting formulaic information scattered throughout a paper in a standard, easy to digest format. SciScore checks for the presence and correctness of RRIDs (research resource identifiers), and for rigor criteria such as sex and investigator blinding. For details on the theoretical underpinning of rigor criteria and the tools shown here, including references cited, please follow this link.
