Objective: Midregional pro-adrenomedullin (MR-proADM) and matrix metalloproteinase-2 (MMP-2) are such proteins, that decreased levels are demonstrated in defective placental functions, as preeclampsia. The aim of the study is to compare maternal serum MR-proADM and MMP-2 levels across pregnancies with intrauterine growth restriction (IUGR), small for gestational age (SGA) and appropriate for gestational age (AGA), to biochemical screen the difference between SGA and IUGR.
Materials And Methods: 180 pregnant women were enrolled in a cross-sectional study: sixty pregnancies diagnosed for IUGR were included in group 1 (IUGR group), sixty pregnancies with SGA were in Group 2 (SGA group) and sixty pregnancies diagnosed for AGA, as control group. Maternal venous blood samples were collected at the time of enrollment, to assess serum MR-proADM and MMP-2 levels, by enzyme-linked immunosorbent assay (ELISA).
Results: The mean maternal serum MR-proADM and MMP-2 levels were lower in the IUGR group than in the SGA and AGA groups ( < .001 and < .001). Maternal serum MR-proADM and MMP-2 cutoffs of 29.985 pg/mL and 1.875 ng/mL were found to be optimal to distinguish IUGR, with sensitivity of 98.3% and 98.3%, specificity of 83.3% and 89.2%, respectively.
Conclusion: Maternal serum MR-proADM and MMP-2 levels were significantly lower in pregnancies with IUGR. Maternal serum MR-proADM and MMP-2 measurements could be used to distinguish IUGR pregnancies from SGA pregnancies.

Aims: This study investigated the association between maternal age and early and late gestational diabetes mellitus (GDM).
Methods: In total, 72,270 pregnant women were included in this prospective birth cohort study. Associations between maternal age and early GDM (diagnosed at <24 gestational weeks) and late GDM (diagnosed at ≥24 gestational weeks) were evaluated using a multinomial logistic regression model with possible confounding factors.

Rationale: Preterm infants diagnosed with bronchopulmonary dysplasia (BPD) are thought to have fewer and larger alveoli than their term peers, but it is unclear to what degree this persists later in life.
Objectives: To investigate to what degree the distal airspaces are enlarged in adolescents born preterm and to evaluate the new Airspace Dimension Assessment (AiDA) method in investigating this group.
Methods: We investigated 41 adolescents between 15 and 17 years of age, of whom 25 were born very preterm (a gestational age <31 weeks, with a mean of 26 weeks) and 16 were term-born controls.
Retrospective observational cohort study of premature neonates screened for ROP with 7 years of follow-up assessing the visual outcomes and adequacy of preschool visual screening.

Background: Very premature infants screened for retinopathy of prematurity (ROP) that do not develop ROP still experience serious visual developmental challenges, and while it is recommended that all children in the UK are offered preschool visual screening, we aimed to explore whether this vulnerable group requires dedicated follow-up.
Methods: We performed a real-world retrospective observational cohort study of children previously screened for ROP in NHS Greater Glasgow and Clyde (Scotland) between 2013 and 2015. We excluded those with any severity of ROP identified during screening.

: This study was aimed to identify the most effective machine learning (ML) algorithm for predicting preeclampsia based on sociodemographic and obstetric factors during the preconception period. : Data from pregnant women admitted to the obstetric clinic during their first trimester were analyzed, focusing on maternal age, body mass index (BMI), smoking status, history of diabetes mellitus, gestational diabetes mellitus, and mean arterial pressure. The women were grouped by whether they had a preeclampsia diagnosis and by whether they had one or two live births.
