Ultrasound evaluation of fetal lung development in utero could be a noninvasive method for frequent monitoring of the state of pulmonary maturity and predicting when parturition could occur with minimum or no risk of respiratory distress syndrome of the newborn. In cases of high-risk obstetric management in premature labor, this ability may be a particularly useful tool. To pursue this possibility, the lungs and livers of 13 living fetal lambs were successfully imaged with a modified clinical B-scanner under carefully controlled conditions; physiologic function tests on the excised lungs determined the state of pulmonary maturity. In eight cases, maturity or immaturity was correctly identified by sonographic criteria. The results wer ambiguous in four cases. One case of immature lung was incorrectly identified as mature. The trends established in these animal studies appear promising and with refinement may form the basis for sonographic assessment of fetal lung maturity in a clinical setting.

: To explore the clinical value of miR-193a-5p in neonatal acute respiratory distress syndrome (ARDS) and its role in ARDS cell model . : RT-qPCR was utilized to detect miR-193a-5p level. Correlation analysis was implemented to assess the correlation between miR-193a-5p and clinical indicators (IL-6, IL-1β, TNF-α, LUS).

Introduction: Maternal infections such as chorioamnionitis could impact fetal lung development by altering cell proliferation and apoptosis. Chorioamnionitis favors the multiple pleiotropic cytokines production such as LIF (leukemia inhibitory factor) and an inflammation-related protein p53. The cytokine production can lead to lung tissue damage and lung disease development.

In this study, we investigated the cytotoxic effect of highly soluble dextran-coated CeO nanoparticles on human fetal lung fibroblasts MRC-5. We examined individual nanoparticle-treated cells by Raman spectroscopy and analyzed Raman spectra using non-negative principal component analysis and k-means clustering. In this way, we determined dose-dependent differences between treated cells, which were reflected through the intensity change of lipid, phospholipid and RNA-related Raman modes.

Methods: The following interventions were identified: antibiotics for preterm premature rupture of membrane, antenatal corticosteroids for fetal lung maturation, partograph use during labor and delivery, induction of labor at or post term, skilled birth care and safe childbirth checklist during labor and delivery. A scoping exercise was conducted to ascertain the most up-to-date evidence, and reviews of topics of interest were updated in case the evidence was not recent, with a focus on low- and middle- income countries (LMICs).
