Published: May 19, 2025

The American College of Obstetricians and Gynecologists just concluded its 2025 annual conference in Minneapolis, Minnesota. From May 16 through May 18, the 2025 ACOG Annual Clinical & Scientific Meeting is the premier destination for individuals in the obstetrics and gynecology fields.

From surgical tutorials to film festivals, professional development, lectures, sessions, and more, the 2025 ACOG Annual Clinical & Scientific Meeting was packed with exciting news, educational insights, and opportunities for networking. Outlined below are just some of the exciting posters presented at the conference.

Comparing Demographics Factors and Outcomes of Pregnant Patients Taking and Not Taking Medication for Opioid Use Disorder in Delaware

Description: As the fourth highest-ranking state for opioid mortality in the country, the study examined the state’s patients who delivered in a single community hospital between January 2018 and December 2021.
Result: The study found that medications for opioid use disorder did not reduce the rate of preterm birth or fetal growth restriction, and there were significant racial disparities in the use of such medications.

Commonly Used Non-Steroidal Anti-Inflammatory Drugs in Obstetrics and Associated Placental Cytotoxicity

Description: The study sought to determine if common NSAIDs have a cytotoxic effect, particularly aspirin and indomethacin.
Result: Aspirin was associated with decreased cell death and a decrease in proinflammatory cytokines. Indomethacin was associated with placenta cellular cytotoxicity.

Antidepressant Exposure and Adverse Neonatal Outcomes: A Population-Based Cohort Study

Description: With the high prevalence of antenatal depression, and the associated health issues, understanding the effects of in utero exposure to antidepressants is critical.
Result: For infants with in-utero exposure to antidepressants, there was a significant decrease in gestational age and birth weight, compared to infants with no exposure.

A Comparison of Neonatal Outcomes Following Inpatient Versus Outpatient Management of Vasa Previa

Description: With limited supportive evidence, antepartum management strategies for vasa previa include inpatient admission and preterm/early delivery. The study compared neonatal outcomes following inpatient and outpatient vasa previa management.
Result: No notable difference between mortality or morbidity between outpatient and inpatient management of vasa previa was observed. There was an observed trend toward earlier delivery and longer newborn hospitalizations for inpatient vasa previa management.

Vitamin D Deficiency and its Association with Preterm Birth from January 2016 to March 2024: Eight Years of Effect

Description: With preterm birth a leading cause of mortality and morbidity around the world, the study investigated the association between gestational age at delivery and vitamin D status.
Result: It was noted that mothers with low vitamin D levels are likelier to deliver preterm. Additional studies will be needed to confirm if supplementing vitamin D during pregnancy could lower the incidence of preterm births.

Platelet Count as an Indicator of Ovarian Malignancy in Women with Ascites

Description: The study was designed to see if platelet count can function as an affordable biomarker to distinguish ascites from cirrhosis versus malignancy.
Result: The study’s findings were that an elevated platelet count may be a discriminatory biomarker for ascites secondary to ovarian malignancy, as compared to ascites secondary to liver cirrhosis.
