· Pediatric heart failure (PHF) features high morbidity and mortality rates.
· Although adults and children can share a common diagnosis of heart failure, the underlying causes can differ significantly and require distinct therapeutic approaches.
· Treatments designed for adults are often applied to PHF despite the fundamental physiological and developmental differences between them.
· Child-specific data are vital for the development of tailored treatments to meet the unique needs of patients with PHF. |

Double-negative T (DNT) cells appear to be increased in several pediatric rheumatic diseases and this finding may be correlated with disease activity to some extent. However, due to significant heterogeneity in several methodological aspects, further investigations in rheumatic children are needed to assess the potential relevance of DNT cells as biomarkers and clarify their immunopathological role. |

Gastrointestinal (GI) allergies are divided into immunoglobulin E (IgE)-mediated, non-IgE-mediated, and mixed types. In addition to non-IgE-mediated, overlapping eosinophilic GI disorders (EGIDs) have increased in Japan. EGIDs, a mixed-type allergy category, include eosinophilic esophagitis (EoE) and non-EoE EGIDs. The number of EoE cases has increased in Western countries, followed by Asian countries. Recent GI allergies may also be associated with type 2 inflammation. |

Questions: Can the serum levels of kisspeptin and DLK1 be potential biomarkers for monitoring the treatments for central precocious puberty (CPP)?
Findings: There were no significant differences in the baseline serum kisspeptin and DLK1 levels in CPP girls compared to girls with premature thelarche (PT). After 6 months of GnRH analogue treatment in CPP girls, median serum kisspeptin levels decreased, while median serum DLK1 levels increased compared to baseline.
Meanings: Serum levels of kisspeptin and DLK1 may serve as novel biomarkers for monitoring the efficacy of treatments for CPP. |

Question: Is the tumor necrosis factor (TNF) signaling pathway (TNF-α-converting enzyme [TACE]/TNF-α/angiotensin converting enzyme [ACE]) involved in pediatric coronavirus disease 2019 (COVID-19) infection?
Finding: Significantly increased circulating TACE/TNF-α and decreased ACE2 levels were noted. TNF-α-308G/A plays a significant role in susceptibility to COVID-19 infection among children. The ACE (I/D) (rs4646994) and ACE2 (rs2285666) single nucleotide polymorphisms lack significant associations with pediatric COVID-19 infection.
