CO2 insufflation has been used instead of air insufflation to reduce postprocedure pain and discomfort in adults; however, adequately powered studies in children are scarce. This randomized controlled trial of 200 children showed that CO2 insufflation reduces postprocedure pain and discomfort during pediatric colonoscopy with no signs of CO2 retention. CO2 insufflation is safe and causes less pain in children. |

Pediatric for invasive group A Streptococcus has resurged globally with increasing severity and toxin-mediated presentations. Beta-lactams remain the first-line treatment, but linezolid has emerged as a safe alternative in cases refractory to β-lactams. Early intravenous immunoglobulin use may improve outcomes in severe streptococcal toxic shock syndrome cases, while C-reactive protein and procalcitonin aid early risk stratification. Integrating global surveillance and individualized therapy is crucial in the postpandemic era. |

The long-term effects of concussion for pediatric patient remains unclear. Children and teenagers do not experience or recover from concussion in the same manner as adults do. Concussions can cause a variety of anatomical and functional alterations. Nonpharmacological approach in pediatric concussion management is an understudied field of research with significant ability to affect prognosis and quality of life. Active rehabilitation and occupational therapy were especially promising. |

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. |

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: 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. |

Compared to PCV13, PCV15 includes 2 (22F and 33F), and PCV20 includes 7 (8, 10A, 11A, 12F, 15B, 22F, and 33F) additional serotypes. The vaccination schedule remains the same: primary doses at 2, 4, and 6 months, and a booster at 12–15 months. If PCV13 was administered in the primary series, PCV15 and PCV20 may be used to complete it or as a booster. |

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. |

Studies indicate potential connections between exposure to endocrine-disrupting chemicals (EDCs) and childhood obesity. Variations in the impact of EDCs in epidemiological studies may result from differences in exposure concentrations and timing, measurement methods, and interactive effects of multiple EDCs. Longitudinal studies on exposure to multiple EDCs are crucial to elucidating their contribution to pediatric obesity and minimize the adverse health consequences of EDC exposure. |
