Preterm delivery is often associated with increased cytokine and chemokine production. These studies characterize the expression of the chemokine monocyte chemotactic protein-1 (MCP-1) in mice during lipopolysaccharide (LPS)-induced preterm delivery. Uterine and other tissues were harvested from CD-1 mice on gestational day 15 after intrauterine LPS injection. Quantitative real-time reverse-transcriptase polymerase chain reactions determined MCP-1 and toll-like receptor 4 (TLR4) mRNA expression during the 24 hours after LPS. MCP-1 protein expression was determined using a cytokine/chemokine protein array, enzyme-linked immunosorbant assay, and immunohistochemistry. Intrauterine LPS injection caused preterm delivery in CD-1 mice between 12 and 24 hours. Expression of MCP-1 mRNA significantly increased at 2 and 6 hours, while TLR4 expression did not significantly change over 24 hours. The MCP-1 protein levels peaked by 2 to 6 hours in maternal serum, liver, lung, kidney, and uterus. Immunohistochemistry confirmed MCP-1 in the myometrium and endometrium. These studies provide evidence suggesting that MCP-1 potentially plays an important role during the proinflammatory immune response, leading to preterm labor in the mouse.

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).
Preconception GLP-1 Receptor Agonist Use Associated with Decreased Risk for Adverse Obstetric Outcomes.

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.

Electronic address:
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.
