MicroRNAs (miRNAs) are highly conserved noncoding RNAs that regulate gene expression by silencing or degrading messenger RNAs. Many of the approximately 2,500 miRNAs discovered in humans are known to regulate vital biological processes, including cell differentiation, proliferation, apoptosis, and embryonic tissue development. Aberrant miRNA expression may have pathological and malignant consequences. Therefore, miRNAs have emerged as novel diagnostic markers and... |

· Pediatric patients have a relatively low incidence of tachyarrhythmia both in acute coronavirus disease 2019 and multisystem inflammatory syndrome in children (MIS-C), but it was associated with an increased risk of poor outcomes. · Conduction abnormalities were not uncommon, especially in those with MIS-C. Most patients recovered to normal sinus rhythm; however, some progressed to advanced atrioventricular block and rarely required permanent pacemaker implantation. |

Most immunocompromised children and adolescents are not at increased risk of developing severe coronavirus disease 2019 (COVID-19). COVID-19 outcomes for low- or medium-risk immunocompromised children are favorable, while more serious illness reportedly occurs in high-risk immunocompromised children by underlying disease, its treatments, and other factors. Therefore, the early detection and timely management of severe COVID-19 and treatment of underlying disease are important. Hospitalization and COVID-19 vaccination should be carefully considered. |
Hearing in neonates and infants is crucial for their development of language and communication skills. Unless hearing loss is appropriately managed early, it can cause a significant socioeconomic burden considering its detrimental impact on the child's development and its common nature. It is also the most common congenital sensory deficit, with an approximate incidence of 1.5 per 1000 newborns. Its... |
Non-alcoholic fatty liver disease (NAFLD), a spectrum of liver diseases characterized by excessive fat accumulation, is the leading cause of chronic liver disease. The global prevalence of NAFLD is increasing in both adults and children.

The identification of the causative pathogens of community-acquired pneumonia and appropriate treatment and prevention can reduce mortality and the socioeconomic burden by reducing the medical expenses. The world has been in the coronavirus disease 2019 pandemic since 2020, and there is always a risk of continuous emergence and epidemic of new respiratory infectious diseases. Therefore, it is important to sustain a monitoring system for respiratory infectious diseases including pneumonia. |

Question: This study aimed to determine whether there is an association between previous abortion history and the risk of autism spectrum disorders (ASDs) among children. Finding: We found that the risk of ASD associated with previous abortion history had an odds ratio of 1.64 (95% confidence interval, 1.28–2.0; I2=61.7%). Meaning: These findings suggest a positive and significant association between history of previous abortion and risk of ASD in children. |
This study aimed to determine whether there is an association between not breastfeeding (versus breastfeeding) and the risk of autism spectrum disorders (ASD) among children. We found that the risk of ASD associated with not breastfeeding had an odds ratio of 1.81 (95% confidence interval, 1.35–2.27; I2=0 %). These findings suggest the importance of breastfeeding in decreasing the risk of ASD among children. |

· Intussusception, the most common cause of small bowel obstruction in young children, has an overall incidence in Korea of 28.3 cases per 100,000 person-years. · Its cause is idiopathic inmost cases, although viral or bacterial gastroenteritis has beenpostulated as a cause. Approximately 4% of children have pathological lead points for intussusception, and Meckel’s diverticulum is the most common cause. · Intussusception in preterm infants is extremely rare. Older children (>5 years of age) are at increased risk of pathological lead points. |

· Children and adolescents with high risks for severe coronavirus disease 2019 (COVID-19) should be identified and proper treatment should be provided promptly according to the patient’s condition. · Remdesivir can be considered for pediatric patients of all ages with COVID-19 who have an emergent or increase in supplemental oxygen. · The use of corticosteroids is not recommended for patients with nonsevere COVID-19. Corticosteroids are recommended in children and adolescents with severe and critical COVID-19. |

Question: What comorbidities are increased in children with congenital muscular torticollis (CMT)? Are there differences in the neurodevelopmental outcomes of children with CMT who received physical therapy versus those who did not? Finding: The risk of congenital musculoskeletal deformities is increased in CMT. Children who did not receive physical therapy were at greater risk of neurodevelopmental delay. Meaning: In CMT, musculoskeletal comorbidities should be identified and active early treatment provided. |
In children with primary dyslipidemia, functional myocardial abnormalities can occur at young age, including diastolic functional impairment of both ventricles and narrowing of the aortic valve and the sinus of Valsalva. Echocardiographic evaluations of high-risk children may be as important as biochemical evaluations. |

The prevalence of Japanese pediatric hypertension is 0.9% based on proper measurement protocols. Hypertensive children tend to be hypertensive adults. Pediatric essential hypertension is characterized by an absence of symptoms, obesity, a family history of hypertension, and a low birth weight. The most common causes of pediatric secondary hypertension are renal parenchymal and renovascular diseases. Important factors controlling pediatric hypertension include healthy lifestyle modifications and pharmacotherapy. |

Question: What is the overall effect of obesity interventions among Korean children and what affects their effectiveness? Finding: Interventions were strongly favored over controls. Interventions including at least one physical activity component were significantly better than those that did not. Sex, age, baseline weight category, intervention duration, and the number of intervention components were not significant. Meaning: Future obesity interventions for Korean children must seek to include physical activity components. |
· Recently, the importance of a short-term treatment regimen including rifamycin has been highlighted in the treatment of latent tuberculosis infection (LTBI). · Four prospective or retrospective studies in children consistently reported that a 4-month daily rifampicin regimen (4R) had a higher completion rate than and comparable safety to a nine-month daily isoniazid regimen. · We suggest rifampicin 20–30 mg/kg/day for children aged 0–2 years and 15–20 mg/kg/day for children aged 2–10 years in 4R to treat LTBI. |

Question: What is the natural course of viral load in children with coronavirus disease 2019 (COVID-19)? Finding: A significant number of patients still had a relatively high viral load once clinically asymptomatic. Nearly half of the patients experienced viral rebound, which contributed to prolonged viral detection in their respiratory specimens. Meaning: Further studies are needed to determine the clinical significance of viral rebound in asymptomatic or mild pediatric cases of COVID-19. |

· Hypertension is defined as a blood pressure (BP) >90th (elevated) or 95th (hypertension) percentile in children by height, age, and sex and >95th percentile in neonates by age, birth weight, and sex. · Although the oscillometric method can be used for screenings, the auscultatory method remains the gold standard. The hybrid method employs the auscultatory and electronic methods and can reduce bias. · BP measurement mobile device applications have a potential for development. |
