Context: Antimüllerian hormone (AMH) levels are higher in patients with polycystic ovary syndrome (PCOS). Accumulating evidence indicates that AMH has an impact on the physiology of the female reproductive system.
Objective: To investigate the association of AMH levels with the risk of preterm delivery in PCOS patients.
Design: Retrospective cohort study.
Setting: Academic fertility center.
Patients: Women who underwent in vitro fertilization between January 2017 and July 2018 (25,165 cycles).
Interventions: None.
Main Outcome Measures: The primary outcome was preterm delivery.
Results: Serum AMH levels were not different between the term delivery and preterm delivery groups in the entire cohort (3.8 vs. 4.1 ng/mL, P>.05). In patients diagnosed with PCOS, those with preterm delivery had higher AMH levels than were found in patients with term delivery (9.3 vs. 6.9 ng/mL, P<.01). Preterm deliveries predominated in PCOS patients with AMH levels above the 75th percentile (9.75 ng/mL) (adjusted P<.0001, adjusted odds ratio [OR] 4.0, 95% confidence interval [CI] 1.94, 8.08)) and frozen-thawed embryo transfer (FET) patients with AMH levels higher than the 90th percentile (10.10 ng/mL) (adjusted P<.05, adjusted OR 2.0, 95% CI 1.16, 3.36).
Conclusion: Serum AMH levels higher than 75th percentile were associated with an increased risk of preterm delivery in patients with PCOS, and serum AMH levels higher than the 90th percentile were associated with an increased risk of preterm delivery in FET patients.

Unbound bilirubin and risk of severe neurodevelopmental impairment in extremely low birthweight newborns.
Pediatr Res
January 2025
Division of Neonatal and Developmental Medicine, Department of Pediatrics, Stanford University School of Medicine, Palo Alto, CA, USA.
Background: Unbound bilirubin (UB) was measured on day 5 ± 1 in 1101 ELBW newborns in the Aggressive vs Conservative Phototherapy randomized controlled trial. We accessed this dataset to quantify the UB-mediated risk of severe neurodevelopmental impairment (sNDI) in extremely low birthweight (ELBW) newborns.
Methods: UB levels were standardized within laboratories as z-score percentiles.
Changes in adrenomedullin in bronchoalveolar lavage fluid with chorioamnionitis in a sheep-based model.
J Matern Fetal Neonatal Med
December 2025
Neonatal Intensive Care Unit, G d'Annunzio University of Chieti, Italy.
Background: Adrenomedullin (AM) is a potent angiogenic, antioxidant and anti-inflammatory peptide protecting the developing lung from injury due to bronchopulmonary dysplasia (BPD) of the preterm infant. At this stage, no data on the potential effects of chorioamnionitis (CA) occurrence and glucocorticoids (GC) administration on AM in developing lungs are still lacking.
Objective: to investigate, in a sheep-based model, the positive/side-effects of combined exposure to CA and GC on AM concentrations measured in bronchoalveolar lavage fluid (BALF).

Background: The use of glucagon-like-peptide-1 receptor agonists (GLP-1RAs) has greatly increased in patients of reproductive age within the past four years. However, there is minimal research into the long-term impact of these medications on future pregnancies.
Objectives: We aimed to evaluate the association between adverse obstetric outcomes and antecedent GLP-1RA use using a nationally representative database.

Background: While guidelines suggest administering antibiotics 12 to 18 hours after the rupture of membranes in term premature rupture of membranes (PROM) women, in practice, clinicians tend to initiate prophylactic antibiotics as soon as possible to avoid risk of infection.
Objective: This study aimed to assess whether early administration of prophylactic antibiotics for term premature rupture of membranes reduces the incidence of maternal and neonatal infections.
Study Design: This multi-center, prospective cohort study included women with term premature rupture of membranes.
An Overview of Early-Life Gut Microbiota Modulation Strategies.
Ann Nutr Metab
January 2025
Department of Paediatrics, Medical University of Warsaw, Warsaw, Poland.
Background: The gut microbiota, or microbiome, is essential for human health. Early-life factors such as delivery mode, diet, and antibiotic use shape its composition, impacting both short- and long-term health outcomes. Dysbiosis, or alterations in the gut microbiota, is linked to conditions such as allergies, asthma, obesity, diabetes, inflammatory bowel disease, and necrotizing enterocolitis in preterm infants.
