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... |
During the last several decades, the number of preterm infants has increased, and their survival rate has improved owing to advances in perinatal care. As more preterm infants survive, many studies examine their neurodevelopmental outcomes. This study aimed to summarize the neurodevelopmental outcomes of preterm infants according to gestational age at birth using a recently published meta-analysis. The prevalence of... |

Some neonates, especially those who are premature, may experience hypertension while in the neonatal intensive care unit (NICU). The most common causes are prematurity-related and the hypertension usually resolves over the first 1–2 years of life. Unfortunately, the increasing population of NICU graduates is at risk for later cardiovascular and kidney disease in childhood and adulthood. This population requires careful attention to blood pressure and weight throughout their life course. |

Question: Plastic feeding bottles are used commonly to feed infants who cannot be breastfeed. Does plastic bottle feeding produce biochemical changes in infants? Finding: The plastic bottles leach out endocrine disruptors and affects bodily functions in terms of biochemical alterations like increased blood urea, raised creatine-kinase–MB levels, and altered lipid profile in infants exposed to bottle feeding. Meaning: Plastic bottles feeding alters bodily functions in infants. |

Nutrients are important in the developing immune system. Human milk supplies diverse bioactives to prevent acute infection or chronic inflammation. Immunoglobulins, lactoferrin, and glutamine in human milk decrease gastrointestinal and respiratory infection. Human milk oligosaccharides promote the growth of intestinal microbiota, the gut barrier, and antimicrobial or antiviral activity. Micronutrients act as anti-inflammatory immunonutrients, too. However, the toxicity of some nutrients from an overdose should be considered. |

∙ Microbial colonization primarily occurs after birth but there may be some colonization in utero, although this remains highly controversial. ∙ Maternal factors during pregnancy affect the infant microbiota: diet, weight, gestational weight gain, and antibiotic usage. ∙ Microbes are passed from mother-to-infant during and after birth. Delivery mode, breastfeeding, early life antibiotic, and proton pump inhibitor treatment have the largest effects on microbial composition in early life. ∙ The early life gut microbiome plays an important role in the development of the immune system and metabolism. |

∙ Exclusively breastfed infants are at risk of developing vitamin D deficiency associated with hypocalcemia, rickets, and various health outcomes. ∙ The prevalence of vitamin D deficiency in breastfed infants differs vastly between studies and nations at 0.6%–91.1%. ∙ The vitamin D content of breast milk does not meet the requirements of exclusively breastfed infants. ∙ Most international guidelines recommend that breastfed infants be supplemented with 400 IU/day of vitamin D during the first year of life. ∙ Vitamin D intake (milk+supplements) of 800 IU/day can be considered in preterm infants along with biochemical monitoring. |

Question: When is the best screening timing and what is the risk factor for developmental dysplasia of the hip (DDH) in preterm infants? Finding: Ultrasonography performed earlier than 38 weeks of postmenstrual age caused unnecessary subsequent ultrasonography. DDH did not occur predominantly on the left side or in breech infants. Meaning: The screening timing, etiology, and risk factors for DDH in preterm infants are somewhat different from those in term infants. |

· Thrombocytosis, common in newborns and infants (<2 years) (3%–13%), is caused by elevated thrombopoietin (TPO) concentrations. · Serum TPO levels are significantly higher immediately to 1 month postnatal and decrease with age. · Platelet counts are positively correlated with gestational age at birth and postnatal age. · Thrombocytosis is more common in preterm than in term infants. · Thrombocytosis in newborns is reactive and resolves spontaneously without complications. |

Question: Are the short-term outcomes of minimally invasive surfactant therapy (MIST) relatively superior to those of INtubation, SURfactant administration, and Extubation (INSURE) in preterm infants with respiratory distress syndrome (RDS)? Finding: MIST could be an appropriate substitution for INSURE in preterm infants with RDS since it reduced hospitalization time and number of side effects. Meaning: MIST is recommended for surfactant administration for its proven advantages over the INSURE technique. |

∙ The growth of preterm infants is a main focus of neonatology. ∙ Preterm infants in Korea, especially those with a very low birth weight, achieve retarded growth. ∙ Careful growth monitoring and early intervention will contribute to better development outcomes and quality of life for preterm infants and improve public health. |

∙ Diphtheria and tetanus toxoids and acellular pertussis-inactivated poliovirus-Haemophilus influenzae type b-hepatitis B (DTaP-IPV-Hib-HepB) was licensed in Korea in April 2020. ∙ DTaP-IPV-Hib-HepB is indicated as a 3-dose primary series for infants aged 2, 4, and 6 months who received the standalone HepB vaccine at birth. ∙ Infants born to HepB surface antigen-positive mothers are currently recommended to be immunized with HepB immunoglobulin at birth and then monovalent HepB vaccine at 0, 1, and 6 months. |

Question: Do probiotics reduce colic symptoms? Finding: Probiotics reduced colic symptoms in colicky infants probably due to the anti-inflammatory properties. Meaning: Probiotics may be an effective and less noxious way to manage infantile colic. |

This national cohort study included all Korean children born in 2008 and 2009 observed over a period of more than 10 years. Our findings demonstrate that it is possible to analyze disease onset prior to hospitalization based on information such as lifestyle, eating habits, and risk factors by integrating National Health Insurance System data with national health screening data. |

· Very low birth weight infants remain at high risk of developing neurodevelopmental impairments in early childhood. · It is important to establish a network follow-up protocol and complete assessments with fewer dropouts to enable clarification of the outcomes of registered infants. · All possible strategies should be employed to maintain good compliance after neonatal intensive care unit discharge. |

Paroxysmal nonepileptic events (PNE) comprise of a variety of nonepileptic behaviors and are divided into various types. A more accurate diagnosis is possible by examining the video clip provided by the caregiver. In infants, physiologic PNE accounts for the majority of the PNE. It is important to exclude epilepsy, for which blood tests, electroencephalography, and imaging tests can facilitate differential... |

Question: Does a tethered maxillary frenulum in the newborn result in breastfeeding difficulty or other oral symptomatology? Finding: The analysis of subjects with a tethered maxillary frenulum surveyed beyond a mean 5-year follow-up did not reveal an increase in oral issues versus those of a random agematched control group. Meaning: These data demonstrate no need to intervene upon the diagnosis of a tethered maxillary frenulum. |

Question: What is the most important factor that increases mortality in infants with hypoxic-ischemic encephalopathy (HIE) who receive selective head cooling? Finding: All cases of neonatal mortality were severe HIE (stage 3), and a severely abnormal amplitude-integrated electroencephalography and mortality were increased with the need for advanced neonatal resuscitation upon delivery. Meaning: Advanced neonatal resuscitation affects HIE outcomes, and medical personnel should be prepared to provide the best intervention. |
