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. |

Traditional morphometric scores often fail to predict the success of biventricular repair of borderline left hearts. Wang et al. demonstrated that a low atrial septal defect (ASD) pressure gradient is a critical functional predictor of mitral valve growth. By integrating ASD hemodynamics with anatomical data, clinicians can better identify candidates for biventricular repair, proving that the "grey zone" is narrower than previously thought and improving outcomes for vulnerable neonates. |

Meta-analyses suggest that virtual reality (VR) reduces self-reported pain, fear, and anxiety in children during needle procedures but has high heterogeneity, high overlap between primary studies, and low methodological quality, leading to a "very weak" GRADE (Grading of Recommendations Assessment, Development and Evaluation) classification. Clinicians should view VR as a promising additional distraction tool; however, VR cannot yet replace current analgesic and anxiolytic strategies. Future research should focus on age-stratified analyses, measurement tool standardization, and modern VR technology |

Pediatric obesity and youth-onset type 2 diabetes have increased simultaneously across 6 continents over the last 25 years. Approximately 75% of affected youths are obese at diagnosis, beta-cell declines occur rapidly, and microvascular complications occur early. Glucagon-like peptide-1 receptor agonists and bariatric surgery achieve meaningful weight loss and glycemic improvement; however, the primary prevention of childhood obesity remains the most powerful strategy for arresting this epidemic. |

Question: Do the loss of function (LOF) of ATP7B mutated variants affect the severity or outcomes of hepatic Wilson disease (WD)?
Finding: LOF is associated with advanced liver disease, portal hypertension, and extrahepatic involvement. LOF did not determine hepatic or overall outcomes. ATP7B: c.813C>A (truncation variant) has an aggressive course with higher predisposition to acute liver failure. Lower serum exchangeable copper levels and higher disappearance of Kayser-Fleischer ring were observed in ATP7B: c.3809A>G (nontruncation variant) suggesting a better effect of chelation and lesser systemic copper.
Meaning: Truncation of the ATP7B protein determines the severity of the phenotype in WD. |

Declining birth rates are reshaping neonatal care. In low-birthrate settings, shifts in the underlying causes of neonatal death, including greater use of perinatal palliative care for trisomy 18 and challenges in maintaining expertise in extremely low-birth-weight infants, may contribute to fluctuations in neonatal mortality. These observations highlight the need for a coordinated system-level support. |
