Objective: The objective of the study was to evaluate the performance of automatic quantitative ultrasound analysis (AQUA) texture extractor to predict fetal lung maturity tests in amniotic fluid.
Study Design: Singleton pregnancies (24.0-41.0 weeks) undergoing amniocentesis to assess fetal lung maturity (TDx fetal lung maturity assay [FLM]) were included. A manual-delineated box was placed in the lung area of a 4-chamber view of the fetal thorax. AQUA transformed the information into a set of descriptors. Genetic algorithms extracted the most relevant descriptors and then created and validated a model that could distinguish between mature or immature fetal lungs using TDx-FLM as a reference.
Results: Gestational age at enrollment was (mean [SD]) 32.2 (4.5) weeks. According to the TDx-FLM results, 41 samples were mature and 62 were not. The imaging biomarker based on AQUA presented a sensitivity 95.1%, specificity 85.7%, and an accuracy 90.3% to predict a mature or immature lung.
Conclusion: Fetal lung ultrasound textures extracted by AQUA provided robust features to predict TDx-FLM results.

Maternal obesity puts the offspring at high risk of developing obesity and cardio-metabolic diseases in adulthood. Here, we utilized a mouse model of maternal high-fat diet (HFD)-induced obesity that recapitulates metabolic perturbations seen in humans. We show increased adiposity in the offspring of HFD-fed mothers (Off-HFD) when compared to the offspring regular diet-fed mothers (Off-RD).

: In the case of threatened preterm birth (PTB) before the 34th week of pregnancy, the application of antenatal corticosteroids (ACSs) for the maturation of the fetal lung is a standard procedure in perinatal medicine. Common diagnoses for ACS use in pregnancy are the preterm rupture of membranes (PPROMs), placental bleeding, premature labor, preeclampsia, oligohydramnios, amniotic infection syndrome (AIS), and cervical insufficiency. The aim of this study was to investigate whether the current diagnosis, which results in ACS, and the patient's risk factors influence the risk of PTB events.

Hematologic complications are common in pregnancy and can significantly impact both maternal and fetal health. Recognizing and treating these complications can be challenging due to the limited evidence available to guide clinical consultants. Iron deficiency anemia is the most prevalent hematologic issue in pregnancy and often occurs due to increased maternal blood volume and the nutritional demands of the growing fetus.

Bronchial atresia (BA) and azygos lobe (AL) are rare congenital pulmonary abnormalities in pediatric patients. We herein report an infantile case of BA combined with AL that was treated with thoracoscopic surgery. The patient was an 8-month-old boy who was preoperatively diagnosed with BA of the right upper lobe (RUL) combined with an AL using fetal magnetic resonance imaging and postnatal enhanced computed tomography.

Fetal limb anomaly presentation varies greatly. It can present as amelia (complete absence of skeletal part of one or more limb), meromelia (partial absence of skeletal part of one or more limb), phocomelia (only rudimentary limb formed), and minor limb disorders like polydactyly. The complete absence of the four fetal limbs is extremely rare.
