Question: What is the level of immunity against meningococcal infections in patients with systemic lupus erythematosus (SLE) under the age of 19, and is vaccination against meningococcus necessary for these patients, given their susceptibility to infections due to immunosuppressive treatments and disease characteristics? Finding: Although some of our study patients exhibited serum bactericidal activity against meningococci, most remained seronegative. Meaning: These findings suggest that patients with SLE who are at risk of meningococcal infection receive appropriate vaccinations. |
|
|
Question: Which immunomodulatory strategies can reduce mortality in children with acute necrotizing encephalopathy (ANE)? Finding: High-dose methylprednisolone (30 mg/kg/day) significantly improved the survival of high-risk patients, particularly when combined with tocilizumab. Meaning: These findings support the use of a severity-based immunotherapy approach to optimize the outcomes of pediatric ANE. |
|
|
Question: Can a balance task with narrowed base of support indicate overall functional balance control in children with disabilities? Finding: While single-limb standing could explain overall balance control for children with disabilities, it was unrelated with balance control for typically developing children. Meaning: One balance task with narrowed base of support can be used as practical assessment of balance abilities for children with disabilities when allocated session time is of concern. |

Approximately 1 in 5 children with acute pancreatitis develops recurrent attacks, and over one-third of such cases progress to chronic pancreatitis. Progression is closely linked to genetic mutations, particularly PRSS1, and anatomical abnormalities, whereas demographic and routine clinical factors lack predictive value. These results support early genetic and anatomical assessments, enabling targeted follow-ups and timely interventions in highrisk pediatric patients. |
| Hematopoietic stem cell transplantation (HSCT) enhances the growth outcomes of pediatric patients with mucopolysaccharidosis, with early intervention leading to improved height, weight, and body mass index. However, achieving a standard adult height remains uncommon among these patients, even in cases of early HSCT. Growth hormone therapy provides short-term benefits but does not address long-term height deficits. Pubertal development is generally normal; however, precocious puberty and pubertal arrest may occur. |

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. |
