Prenatal diagnosis of amniotic fluid enables the evaluation of fetal lungs maturity. The aim of the study is to evaluate prognostic significance of measurement of concentration of lamellar body count (LC) in comparison with other laboratory investigations for prenatal fetal lung maturity evaluation. The study was carried out on 60 amniotic fluid collections obtained by amniocentesis of pregnant women, hospitalized in Polish Mother's Health Centre between August 1998-January 2000. Following tests were performed: phosphatydyloglicerol concentration (PG), concentration of lamellar body (CLC), optical density-reading absorbance in wave length 400, 570, 650 nm. Test PG showed 70% specificity and 100% sensitivity, LC 70% specificity; 100% sensitivity. PG and LC showed good correlation for the assessment of fetal lung maturity. The study involved small number of patients pointed out the necessity of continuation quantitative investigation of LC to confirm diagnostics utility for the assessment of fetal lung maturity.

Alveolar type 2 (AT2) cells maintain lung health by acting as stem cells and producing pulmonary surfactant. AT2 dysfunction underlies many lung diseases, including interstitial lung disease (ILD), in which some inherited forms result from the mislocalization of surfactant protein C (SFTPC) variants. Lung disease modeling and dissection of the underlying mechanisms remain challenging due to complexities in deriving and maintaining human AT2 cells ex vivo.

IKKα, encoded by CHUK, is crucial in the non-canonical NF-κB pathway and part of the IKK complex activating the canonical pathway alongside IKKβ. The absence of IKKα causes fetal encasement syndrome in humans, fatal in utero, while an impaired IKKα-NIK interaction was reported in a single patient and causes combined immunodeficiency. Here, we describe compound heterozygous variants in the kinase domain of IKKα in a female patient with hypogammaglobulinemia, recurrent lung infections, and Hay-Wells syndrome-like features.

Objectives: Congenital thoracic masses (CTMs) are suspected in presence of solid or cystic thoracic lesions at ultrasound. The common typical fetal CTMs encompass: hyperechogenic lung lesions such as congenital pulmonary airway malformation (CPAM), broncopulmonary sequestration (PS) and congenital high airway obstruction syndrome (CHAOS); less common solid thoracic masses are mediastinal/pericardial tumors as rhabdomyoma and teratoma. The aim of our study is to gather the available evidence on cases of atypical CTMs of difficult classification, for which the diagnosis remains often uncertain.

Previous studies suggest that NIPT's implementation differed widely across countries but offer limited insight into what shaped these differences. To address this gap, we conducted an in-depth analysis of how NIPT was incorporated into prenatal care in the US, the Netherlands, and Japan-countries with similar economic status-to identify actionable lessons. We conducted an integrative literature review on the process of introducing and implementing NIPT, stakeholders' roles, documented considerations in the decision to introduce NIPT, implementation choices, and NIPT uptake.

Background: Suboptimal cardiovascular health (CVH) in pregnancy is associated with adverse maternal and offspring outcomes. To guide public health efforts to reduce disparities in maternal CVH, we determined the contribution of individual- and neighborhood-level factors to racial and ethnic differences in early pregnancy CVH.
Methods: We included nulliparous individuals with singleton pregnancies who self-identified as Hispanic, non-Hispanic Black (NHB), or non-Hispanic White (NHW) and participated in the nuMoM2b cohort study (Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be).
