A series of experiments shows that biological aging of tracheobronchial stem cells could drive the development of chronic lung disease. In a recent publication in STEM CELLS Translational Medicine (SCTM), researchers showed that repeated injury to epithelial cells in the airway caused biological aging of the stem cells located there. Tracheobronchial stem cells (TSCs) are…

A single dose of a novel live probiotic therapeutic protects the rodent brain during early development and the effects persist into adolescence. Researchers at Nationwide Children’s Hospital have demonstrated that when given in a biofilm state, probiotic Lactobacillus reuteri prevents the detrimental neurodevelopmental sequalae of experimental necrotizing enterocolitis (NEC).1 The findings, published in Brain, Behavior…

Most infants with established BPD referred to Nationwide’s BPD Center improve and survive, despite the severity of their illness. In a new study, researchers analyzed the in-hospital outcomes for preterm infants with established bronchopulmonary dysplasia (BPD) referred to Nationwide Children’s Comprehensive Center for BPD. They found that despite the high degree of illness severity in…

Inconsistency among studies prompted researchers to take a closer look at the drug’s effects. Despite limited evidence supporting its use, prophylactic indomethacin treatment is often administered to very preterm infants within the first 24-hours after birth to reduce the risks of intraventricular hemorrhage and longer-term neonatal morbidities, such as bronchopulmonary dysplasia (BPD). Data from a…

Categorizing infants with pulmonary vein stenosis into stable and progressive groups could help inform treatment. Primary pulmonary vein stenosis is a rare, often lethal, cardiac disease. It is challenging to treat, as the disease can be progressive in some patients but not others. In a new study, researchers from Nationwide Children’s describe outcomes among preterm infants…

Pulmonary hypertension is high blood pressure in the lungs and is a comorbidity of bronchopulmonary dysplasia (BPD), which is the chronic lung disease of premature babies. When pulmonary hypertension is present in the context of BPD, the risk of death is significantly increased.

A positive fluid balance is associated with acute kidney injury and worse outcomes in a new study of premature infants. According to new research, there is an association between fluid balance and outcomes in preterm newborns, with a negative fluid balance during the first week of life emerging as a potential therapeutic target.

ARI severity plays little role in symptom generation, but symptoms alone are unreliable for diagnosing gastroesophageal reflux disease, researchers say. However, a new study from the Neonatal and Infant Feeding Disorders Program at Nationwide Children’s Hospital shows that stomach acid alone doesn’t appear to have much to do with GERD at all, and responses to esophageal stimulation…
