· Pediatric chronic cough often involves eosinophilic inflammation; however, objective measurements are not routinely used in treatment decisions.
· Accurate biomarkers of eosinophil activity, such as eosinophil-derived neurotoxin (EDN) and cationic proteins (ECP), should be used. EDN, which overcomes the shortcomings of ECP, recently received approval for use in Korean healthcare settings.
· EDN and ECP can play a role in treatment period and drug selection decisions. |

Question: Can hematopoietic stem cell transplantation (HSCT) cure pediatric transfusion-dependent thalassemia in Thailand? What influences its outcomes?
Finding: Among 266 HSCT procedures, 5-year overall survival and event-free survival rates were 91.3% and 81.0%, respectively. Outcomes were comparable between related and unrelated donors. Pre-HSCT ferritin >2,500 ng/mL, low CD34+ cell dose, and oral busulfan conditioning were associated with unfavorable survival. Longterm complications affected 22.7% of survivors.
Meaning: Optimizing pre-HSCT care, ensuring adequate grafting, and long-term surveillance are crucial. |

Shared decision-making (SDM) offers an ethically grounded, relational approach to making difficult decisions in neonatal care. Its effective use depends on recognizing when its use is appropriate and enacted in clinical conversations. In Korea, while parents are often involved in decision-making, SDM is not yet consistently articulated or evaluated as a structured practice. Culturally grounded research, education, and institutional support are needed to strengthen family-centered neonatal care. |

Positive pressure ventilation (PPV) is the most critical intervention provided during delivery room resuscitation. In the new guidelines, this recommendation has been expanded to suggest the use of laryngeal mask airyway (LMA) versus face masks for PPV. Evidence-based information and hands-on training related to this practice will help more healthcare providers become familiar with and appropriately use LMA during delivery room resuscitations. |

· 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. |

· The proper monitoring for and treatment of coronavirus disease 2019 (COVID-19)-induced acute kidney injury, which is common in critically ill children, are recommended.
· Glomerulopathy associated with COVID-19 or its vaccination has been reported, and the overall clinical course is similar to that of non-COVID-19-associated diseases.
· Additional COVID-19 vaccinations are recommended; however, careful and individualized decisions should be made in patients with COVID-19- or vaccination-associated glomerulopathy. |

Question: How have epilepsy and cognitive outcomes of children with infantile epileptic spasms syndrome (IESS) evolved over the past 20 years?
Finding: Approximately 78% of children developed chronic epilepsy, and one-third progressed to drug-resistant epilepsy, while 90% of them exhibited intellectual disabilities.
Meaning: Given the poor outcomes associated with IESS, consensus guidelines tailored to Korean clinical practice are required to ensure timely treatment and improve outcomes. |

Liver transplantation (LT) is crucial for children with end-stage liver diseases, yet bloodstream infections (BSI) pose significant risks, despite medical advancements. Immunosuppressants, essential for preventing organ rejection, heighten infection susceptibility. Understanding BSI organisms is vital due to antimicrobial resistance. Pediatric LT recipients have unique risk factors, demanding tailored preventive measures. This systematic review on bacterial BSI emphasizes the urgency of effective prevention strategies, considering the high incidence and distinct organism profile. Further research is vital for optimizing antibiotic management and improving outcomes for this vulnerable population. |

Newborns born to mothers infected with coronavirus disease 2019 (COVID-19) should be closely monitored for respiratory disorders, such as transient tachypnea of the newborn, regardless of their COVID-19 test results. Further research is required of the development of infants born to mothers with COVID-19. The trends in Korea's birth rate and infant mortality rates have not been significantly affected by COVID-19. |

Question: In pediatric acute lymphoblastic leukemia (ALL), what are the incidence and causes of induction-phase acute kidney injury (AKI), and which factors predict chronic kidney disease (CKD)?
Finding: Induction AKI occurred in 43% of patients, while CKD developed in 1 of 8 patients. The 5-year CKD-free survival rate was 94%. Older age at diagnosis was a continuous independent determinant of CKD risk.
Meaning: Induction AKI is common and clinically relevant. Older children warrant closer kidney monitoring during and after therapy. |

Height, weight, and body mass index percentiles should be tracked in routine childhood health checkups to address the age of adiposity rebound in early childhood. Comprehensive interventional lifestyle counselling in primary practice after growth and nutritional status assessments might be an early, effective strategy for preventing obesity and decreasing the double burden of disease in later life. Therefore, there is an urgent need for a cooperative and supportive health care system. |

Pediatric sarcopenia is common in chronic gastrointestinal and liver diseases, often hidden by normal body mass index or obesity, and predicts worse outcomes. Because growth and puberty alter body composition, assessment should use age- and sex-specific measures of muscle mass and, when feasible, function. Early multidisciplinary intervention—protein-adequate nutrition, resistance-based activity, and disease control—may improve prognosis. |
