Question: Does the gut microbiota differ between very low birth weight (VLBW) infants with versus without bronchopulmonary dysplasia (BPD)? Finding: Common respiratory pathogens were notably elevated in the BPD group, whereas anaerobic and butyrate-producing taxa, key components of postbiotics, were dominant in the non-BPD group. Meaning: In gut-lung communication, the interplay between the intestinal and respiratory systems may implicate pro- and postbiotics in VLBW infants with BPD. |

Question: Can sigh breaths (Sighs) application during high-frequency oscillatory ventilation (HFOV) decrease partial pressure of carbon dioxide (PaCO2) levels? Finding: The mean PaCO2 level after Sighs during HFOV was significantly decreased compared to that after HFOV alone (mean difference, -3.6 mmHg). Meaning: HFOV plus Sighs functionality can reduce PaCO2 levels. However, further studies are required to conclusively determine the effects of Sighs. |

With advancements in neonatal intensive care, the limit of viability has shifted to 22–23 weeks' gestation, whose survival rates vary across countries and institutions. These rates are not static and can be improved through the proactive and centralized care guided by national protocols, including maternal transfer to high-activity regions with better neonatal intensive care practices before delivery. |

Intermittent sigh breaths during high-frequency oscillatory ventilation can improve ventilation and oxygenation by enhancing lung recruitment. Although research on this approach in newborn infants is limited, some published studies suggest that sigh breaths are generally applied at a rate of 2–3 breaths/min with an inspiratory time of 0.5–1 second and pressure of current mean airway pressure + 5 cmH2O (maximum, 30 cmH2O). |

· Pediatric heart failure (PHF) is a clinical syndrome featuring various symptoms (shortness of breath, ankle swelling, fatigue) and signs (pulmonary crackles, peripheral edema). · Congenital heart diseases are the most common underlying etiology of PHF, whereas myocarditis and primary cardio-myopathies are common in children without structural ab-normalities. · PHF pathophysiology is complex and multifactorial and varies by etiology and age. · PHF management includes decongestive therapy, treatment of underlying causes, preventing progression, and managing pulmonary or systemic obstructions. · Drugs should be chosen based on pharmacodynamics, clinical manifestations, hemodynamic state, and renal function. |

Question: What are common tantrum behaviors in preschool children, and how frequently are problematic behaviors observed? Do problematic tantrums have a different emotional impact on caregivers compared to typical tantrums? Finding: Temper tantrums are common in preschool children, and verbal tantrums are the most common type. Meaning: Problematic tantrums, defined as tantrums exhibiting aggressive physical behavior, long duration (>15 minutes), or frequent occurrence (>3 days/wk), significantly affected caregivers’ emotions. |

· Inflammatory responses accompanying fever increase neuronal excitability in the central nervous system, which in turn provokes seizures. · Fever in children with febrile seizures is usually caused by common respiratory viruses, the distributions of which match those of seasonal community-acquired respiratory tract infections. · Several genetic variations in ion channels seem associated with neuronal hyperexcitability in children with febrile seizures. |

Pediatric asthma can persist to adulthood and must be effectively managed. This review examined the prevalence of asthma among individuals younger than 20 years and revealed a decline from 1990 to 2021, higher rates in males, and a peak in children aged 5–9 years. Despite a projected continued decrease in prevalence by 2050, asthma will remain a significant health concern for children and adolescents. |

Myopia is a major ophthalmological disorder with increasing prevalence worldwide, particularly in East Asia. Evidence indicates that its development involves complex interactions between genetic and environmental factors. Body stature, sleep patterns, and nutritional status significantly influence the progression of myopia during childhood and adolescence. Its treatment and prevention strategies include optical correction, atropine therapy, increased outdoor activity, decreased near work, and regular retinal monitoring. |

Question: What emotions do parents experience when their newborns are admitted to the neonatal intensive care unit (NICU)? Finding: Mothers experienced more anxiety (51%), depression (31%), and stress (41%) symptoms than fathers (26%, 12%, and 22%, respectively). Meaning: Parents often experience anxiety, stress, and depression following NICU admission. Healthcare workers are responsible for providing regular parental counseling. |

The incidence of childhood obesity is increasing worldwide. National surveys in Malaysia have shown similar trends. This review aimed to increase our understanding of the prevalence and associated factors of childhood overweight, obesity, and excess weight in Malaysia. A systematic review and meta-analysis were conducted of studies reporting the prevalence of overweight and obesity in Malaysian children aged <18 years.... |

Question: Does zinc supplementation along with probiotics affect disease severity or clinical outcomes of children with acute diarrhea? Findings: This study indicated that zinc supplementation and probiotics had no effect on clinical improvement or disease severity among pediatric patients with acute diarrhea. Meaning: Children who received probiotics plus zinc recovered faster than those who received probiotics only. |

Question: Do community members and health providers show different level of knowledge, attitude, and practice towards dengue vaccine? Finding: These 2 groups only differed in practice component, while the knowledge and attitude constituents were relatively low for both. Meaning: There is an urgent need to deliver educational interventions to raise awareness of community members and health providers regarding dengue vaccination. |

· Allergic march occurs in a subset of children, beginning with atopic dermatitis and progressing to food allergies, allergic rhinitis, and/or asthma. Its early diagnosis is important to slowing its progression. · Eosinophil-derived neurotoxin (EDN), an excellent biomarker of eosinophil activity, is often elevated in allergic diseases. · EDN levels have been used to predict allergic disease development and diagnose, treat, and monitor allergic diseases. |

Question: What are the most common enteric pathogens in acute diarrhea among children younger than 5 years of age, and which age group is most susceptible? Finding: Bacteria were the most common causative microorganisms of diarrhea, followed by viruses, parasites, and fungi. The 1–2-year age group was the most commonly affected. Meaning: There is a need to formulate preventive strategies targeting children exposed to enteric pathogens to limit diarrhea. |

Question: Postinfectious bronchiolitis obliterans (PIBO) is a chronic respiratory disease that typically develops in children after a severe respiratory infection. Bronchopulmonary dysplasia (BPD) is often comorbid in patients with PIBO. Finding: Corticosteroid pulse therapy effectively manages PIBO with or without comorbid BPD, significantly reducing exacerbations and decreasing the daily requirement for inhaled corticosteroids. Meaning: Therapeutic effects of corticosteroid pulses are rapid and sustained over time, in both groups. |
· Iron deficiency (ID), the most common cause of anemia, can be classified into absolute and functional types. Absolute ID is a state of low total body iron, while functional ID is a state of imbalance between iron demand and iron availability due to inflammation and/or infection. · ID is diagnosed by serum ferritin and transferrin saturation levels. |

Eosinophilic gastrointestinal disorders (EGIDs) often coexist with functional gastrointestinal disorders (FGIDs) and other IgE or non-IgE mediated GI diseases. Diagnosing EGIDs requires a high index of suspicion and a comprehensive approach to differentiate them from conditions like inflammatory bowel disease. Tests such as fecal calprotectin and biopsies aid in severe cases. Maintaining a food diary helps identify triggers for long-term elimination. Awareness and education are key to effective management. |
