Prevalence of Persistent Pulmonary Hypertension of the Newborn and Associated Factors in Term Neonates Born in Southeast of Iran, 2020
Background and purpose: Infants with persistent pulmonary hypertension (PPHN) are readmitted to hospital three times more than other infants or die after discharge. The disease imposes a high cost on families and health systems. In this study, for the first time, the prevalence of PPHN and associated factors were investigated in mature neonates born in southeast of Iran. Materials and methods...
متن کاملPersistent Pulmonary Hypertension of the Newborn

It is a clinical syndrome characterized by respiratory distress, hypoxemia, elevated pulmonary vascular resistance and a right to left shunting of venous blood across the foramen ovale and/or ductus arteriosus.

متن کاملMaternal tobacco smoke exposure and persistent pulmonary hypertension of the newborn.
We propose that in utero exposure to tobacco smoke products places a newborn at risk for persistent pulmonary hypertension of the newborn (PPHN). To test this hypothesis, infants with PPHN were identified. Healthy newborns of similar ethnicity were identified as a comparison group. Cord blood cotinine concentrations and maternal questionnaires were obtained. The number of women exposed to tobac...
متن کاملHypoxia inducible factor signaling and experimental persistent pulmonary hypertension of the newborn
BACKGROUND Mitochondrial reactive oxygen species (ROS) levels and nuclear factor kappa-light-chain-enhancer of activated B cells (NFκB) activity are increased in a lamb model of persistent pulmonary hypertension of the newborn (PPHN). These events can trigger hypoxia inducible factor (HIF) signaling in response to hypoxia, which has been shown to contribute to pulmonary vascular remodeling in r...
متن کاملPersistent Pulmonary Hypertension of Non Cardiac Cause in a Neonatal Intensive Care Unit
Parenchymal lung diseases are the main cause of persistent pulmonary hypertension of the newborn (PPHN). We aimed to assess the non cardiac conditions associated to PPHN in the newborn and the survival rate over the last 15 years, at our center. A retrospective chart review of the neonates admitted for PPHN from 1996 to 2010 was performed. New therapies were introduced in 2003, and the survival...
