The overall objective of this study is to investigate the role of metformin in decreasing lung injury and promoting lung growth in premature infants. There are two phases to this pilot study. For Phase 0, the goal is to investigate the safety and tolerance of oral metformin in premature who have been diagnosed with bronchopulmonary dysplasia (BPD) at 36-44 weeks gestation. For Phase 1, the goal is to investigate metformin safety and tolerance in extremely premature infants who are 7-30 days old who have an increased risk of BPD. The main questions it aims to answer are: * how well do older premature infants tolerate metformin? * how well do younger premature infants tolerate metformin?
Hospitalized infants with severe bronchopulmonary dysplasia (BPD) and feeding intolerance will be randomized to 2 weeks of continuous gastric feeding or continuous transpyoloric feeding. Subjects will crossover after 2 weeks and receive 4 weeks of each feeding mode. Respiratory status will be assessed to determine the optimal feeding mode for each infant.
The goal of this clinical trial is to learn if transpyloric tube feeding (feeding directly into the small intestine) versus gastric tube feeding tolerably and effectively reduces gastroesophageal reflux in infants born premature who have been diagnosed with bronchopulmonary dysplasia. The main questions this trial aims to answer are: Does transpyloric as compared to gastric tube feeding result in differences in the amount of experienced hypoxemia (low oxygen level in the blood) or serious adverse events? Does transpyloric as compared to gastric tube feeding reduce the frequency and severity of gastroesophageal reflux (GER) measured using 24 hour esophageal pH-multichannel intraluminal impedance (pH-MII) monitoring? Participants will: Undergo pre-trial 24 hour pH-MII monitoring to determine baseline severity of GER. Be randomly assigned to receive transpyloric or gastric tube feeding for 2 weeks. Undergo repeat pH-MII at the end of the 2 week trial to assess for change in GER. Undergo continuous pulse oximetry to record level of hypoxemia during the 2 week trial. Undergo saliva and airway (if supported by a breathing tube) fluid collection to measure biomarkers of GER. Be monitored clinically for possible adverse events.
Bronchopulmonary Dysplasia (BPD), or chronic lung disease of prematurity, is the most consequential complication of preterm birth and is strong predictor of childhood pulmonary and neurodevelopmental disability, particularly in infants diagnosed with grade 3 BPD (ventilator dependence at 36 weeks' postmenstrual age), the most severe disease form. This study aims to (1) generate the first empirically defined phenotype classification system for grade 3 BPD developed using a rich array of objective and quantitative cardiopulmonary diagnostic, clinical, and biological data; and (2) define the association between phenotype subgroups and neurodevelopmental and respiratory outcomes through 2 years' corrected age.
The purpose of this pilot study is to compare if keeping infants on CPAP (continuous positive airway pressure) support for an extended period of time until they are 32 weeks corrected gestational age or 1250 grams (approximately 2 pounds and 12 ounces) will decrease their degree of lung disease as compared to weaning their respiratory support to HFNC (high flow nasal cannula).
In this pilot study, the investigator team aims to evaluate whether standardized prone positioning compared to usual positioning improves moderate to severe bronchopulmonary dysplasia (BPD) rates as assessed at 36 weeks post conceptional age in very low birth weight preterm infants with bronchopulmonary dysplasia.
The purpose of this study is to determine if an investigational drug, AT-100, can reduce the occurrence of Bronchopulmonary Dysplasia (BPD) in babies born premature, as compared to babies born premature who receive an air-sham alone.
The primary objective of this study is to provide expanded access of S-nitrosylation therapy for the treatment of bronchopulmonary dysplasia
This is a multicenter, randomized, placebo-controlled, sequential dose-escalating, double-masked, safety study of sildenafil in premature infants (inpatient in Neonatal Intensive Care Units (NICUs)) with severe bronchopulmonary dysplasia (BPD).
The purpose of this study is to use forced oscillometry technique (FOT) to measure pulmonary mechanics and function in in term infants and premature infants with bronchopulmonary dysplasia (BPD)
