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. |

Question: How do structural and staffing characteristics of neonatal intensive care units (NICUs) influence the mortality rates of very low birth weight infants (VLBWIs)? Findings: NICUs with higher staffing levels, particularly with more neonatologists, and those offering advanced care levels were associated with lower mortality rates. Additionally, regional disparities were observed, with some areas demon-strating significantly higher survival rates. Meaning: Adequate staffing and equitable regional distribution of medical resources are crucial for improving survival outcomes in VLBWIs. Efforts to enhance NICU staffing and address regional healthcare disparities are essential for optimizing care quality and reducing mortality in this vulnerable population. |

This review aimed to determine whether pesticide exposure is associated with stunting in children. The 13 included studies agree that pesticide exposure is not correlated with stunting incidence regardless of substance type (organophosphate and pyrethroid). Heterogeneity appeared with age covariate as potential confounding. The evidence of this study is challeng-ing, as the adverse effects of pesticides grossly occurred. The protection of children is warranted for preventing future neurodevelopment issues. |

Ethnic variations may influence the response of children and adolescents to obesity pharmacotherapy. Current evidence does not show consistent differences in efficacy or safety among ethnic groups; however, available data are limited. Larger, ethnically diverse trials are needed to develop personalized obesity treatment strategies. |
|
|
Question: Does obesity in preschool children affect lung function, and which obesity indices can predict such alterations? Finding: Preschool children with obesity exhibit impaired lung function characterized by elevated total and peripheral airway resistance. Waist-to-height ratio was the strongest predictor of such changes. Meaning: Early obesity prevention and treatment are needed. Monitoring waist-to-height ratio, body weight, and body mass index may help identify children at risk of altered lung function. |

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. |

Question: Can face masks alter pulmonary pressure in children and adolescents with and without congenital heart disease? Findings: Mask removal during echocardiography (ECHO) reduced pulmonary pressure. Meaning: These findings suggest that face masks should be removed during ECHO in children and adolescents. |
|
|
Question: Does human leukocyte antigen (HLA)–B*58:01 increase the risk of cutaneous reactions in pediatric patients with hematological and oncological diseases receiving allopurinol? Finding: : Of 108 patients, 17.6% carried HLA–B*58:01 but none developed skin reactions. The only rash occurred in an HLA-B*58:01–negative patient. Meaning: Short-duration allopurinol may mitigate severe cutaneous adverse reaction risk regardless of genotype. Routine HLA-B*58:01 screening may be unnecessary in pediatric patients with hematological and oncological diseases briefly receiving allopurinol. |
|
|
Question: In children with proliferative lupus nephritis, do National Institutes of Health-modified indices and treatment choices predict long-term kidney function? Finding: Higher chronicity index scores, especially tubular atrophy and interstitial fibrosis, predicted kidney impairment. Additionally, the use of mycophenolate mofetil (MMF) for maintenance therapy was associated with a lower risk of kidney function decline. Meaning: The early recognition of chronic lesions and MMF-based maintenance therapy may improve kidney outcomes in childhood-onset lupus nephritis. |

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. Meaning: The TNF signaling pathway participates in pediatric COVID-19 infection. |
|
|
Question: Is bronchopulmonary dysplasia (BPD) associated with functional/structural abnormalities later in life? Finding: School-aged children with severe BPD had abnormalities on pulmonary function tests and lung computed tomography despite no subjective respiratory symptoms; however, only prenatal oligohydramnios and prolonged ventilator use were associated with abnormal lung function. Meaning: Long-term monitoring of preterm infants’ lung health is essential, especially for those with prenatal oligohydramnios or prolonged ventilator use. |
|
|
Question: Are pediatric patients with heart disease who are receiving diuretics at risk of thiamin deficiency (TD)? Finding: Fifteen percent of the patients had TD. TD was associated with inadequate dietary thiamin intake and increasing age. Meaning: The thiamin pyrophosphate effect should be assessed in those with high risk of TD. Dietary counseling should be emphasized to ensure adequate dietary thiamin intake. |
|
|
Question: Is there a nonlinear relationship between neutrophil-to-lymphocyte ratio (NLR) and asthma in children and adolescents? Finding: NLR showed a nonlinear association with asthma, with an NLR threshold of 2.23 identifying individuals at higher risk. Meaning: An NLR<2.23 may serve as a potential biomarker for asthma risk assessment and management in pediatric populations, thereby offering a simple tool for the early identification of at-risk individuals. |

Question: What is the optimal dose of bone marrow-derived mesenchymal stem cells (BM-MSCs) for treating necrotizing enterocolitis (NEC), and is orally administered BM-MSC effective? Findings: High (1×106 cells) or multiple BM-MSC doses showed similar effects as low (1×105 cells) doses of intraperitoneally administered BM-MSCs. Furthermore, orally administered BM-MSCs were as effective as intraperitoneally administered BM-MSCs. Meaning: Orally administered low-dose BM-MSCs are a potential treatment for NEC. |
|
|
Question: Could hematopoietic stem cell transplantation (HSCT) be an alternative to enzyme replacement therapy (ERT) for type VI mucopolysaccharidosis (MPS VI)? Finding: HSCT is generally not offered due to reports of high toxicity and mortality. However, we detected fewer complications and graft-versus-host disease cases and no deaths with HSCT. Meaning: HSCT is both less expensive than ERT and permanent; thus, it should be considered an alternative treatment for MPS VI. |
