Question: Is bronchopulmonary dysplasia (BPD) associated with functional/structural abnormalities later in life?
Finding: School-aged children with severe BPD had abnormalities on pulmonary function tests and lung computed tomography despite no subjective respiratory symptoms; however, only prenatal oligohydramnios and prolonged ventilator use were associated with abnormal lung function.
Meaning: Long-term monitoring of preterm infants’ lung health is essential, especially for those with prenatal oligohydramnios or prolonged ventilator use.

The overall incidence of bloodstream infections was 23.5%. Gram-negative organisms occur at a much higher rate in pediatric liver transplant recipients then that the general pediatric population. However, when comparing pediatric and adult liver transplant recipients Gram-positive organisms occur with a much higher rate in the pediatric population highlighting the importance of early and broad spectrum antimicrobial coverage when bloodstream infections are suspected.

A recent unexplained acute kidney injury (AKI) outbreak due to pharmaceutical product contamination with diethylene glycol (DEG) raises public attention. Our study revealed that DEG-contaminated paracetamol causes unexplained AKI in children. However, paracetamol is not the only contaminated drug. Other drugs, such as cough expectorants, antihistamines, and sedatives, can also be affected. Other chemicals, such as ethylene glycol and propylene glycol, can also contribute to poisonings.

· Clinical studies of coronavirus disease 2019 (COVID-19) in infants should be supported by rigorous laboratory diagnostic criteria.
· Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spreads to infants similarly to other viral respiratory infections.
· Among infants ≤1 year of age beyond the immediate postpartum period, COVID-19 is relatively mild, but even the low risk of severe disease requires prevention.
· Comorbidities increase infection vulnerability and complications in infants.
· Clinical and laboratory data do not sufficiently distinguish COVID-19 from other respiratory viral infections.
· Coinfection with SARS-CoV-2 is uncommon among infants.
· Unique infection sequelae, including multi-inflammatory syndrome in children and neonates and long COVID require further study and refinement of diagnostic criteria.
· Infection control standards applied to mother-infant dyads should be tempered by standard preventive strategies, maternal input, accommodation potential, and overall safety.
· Maternal vaccination prevents disease in early infancy.
