On October 9, 2025, the ACOG released a clinical practice update (CPU) regarding Zouranolone and brexanolone. As postpartum depression is an area of continued research and need for therapeutics, any new clinical practice update on the subject is welcome. So what's new in this update?! Well…the answer will surprise you. Listen in for details on the CPU, and a mini-review of the concerns for Zuranolone. 1.

Sometimes you hear something that makes you just stop and say, “What did you say?!”. Yep, in this episode we will give evidence-based answers to three questions that I heard TODAY that made me stop and ask, “What did you say?”. In this episode we will cover: 1. Umbilical cord blood collection from a monochorionic twin gestation, 2. Predictability of the mBPP compared to full BPP, and 3. Breastfeeding during postpartum cannabis use (this last one is not so intuitive as you would think, and there is new ACOG guidance on this which we will review). Listen in for details! 1.

In July 2023, the ACOG released a Practice Advisory stating, “Based on data on the benefit of adjunct HPV vaccination, ACOG recommends adherence to the current Centers for Disease Control and Prevention (CDC) recommendations for vaccinations of individuals aged 9–26 years, and to consider adjuvant HPV vaccination for immunocompetent previously unvaccinated people aged 27–45 years who are undergoing treatment for CIN 2+”. The possible beneficial effect of peri-treatment HPV vaccination goes back to the early 2010s. But science is always changing, and MEDICINE MOVES FAST. In September 2025, the Lancet’s Obstetrics, Gynecology, and Women’s Health journal published the VACCIN trial to test that guidance. These authors found that, “Although previous studies, including meta-analyses and observational studies, have shown that adjuvant HPV vaccination reduces the recurrence of cervical dysplasia after surgical treatment, our trial suggests that adjuvant HPV vaccination is not effective in reducing the recurrence of CIN 2–3 lesions, contradicting the conclusions of previous works”. They have also called for a REVISION to prior guidance. This is FASCINATING. Listen in for details. 1.

FYI

A breakthrough discovery in the 1970s was the determination of alpha-fetoprotein levels in the serum of pregnant women to detect fetuses with neural tube defects. In the case of high AFP values in maternal serum, amniocentesis was performed to determine the levels of AFP and acetylcholinesterase (AChE) in the amniotic fluid to confirm the diagnosis. Currently, the ACOG states that high-quality, second-trimester fetal anatomy ultrasonography is an appropriate screening test for NTDs where routinely performed for fetal anatomic survey at 18 to 22 weeks. If optimal images of the fetal spine, intracranial anatomy, or anterior abdominal wall are not obtained (eg, fetal position or maternal obesity), MSAFP should be performed to improve detection of NTDs (ACOG Practice Bulletin No. 187: Neural Tube Defects. Committee on Practice Bulletins Obstet Gynecol. 2017). Some clinicians (as we do in our practice) order both fetal anatomy ultrasound and msAFP concurrently. What are the implications when the msAFP is elevated with a normal fetal anatomical survey? Where is this msAFP coming from? Listen in for details. 1.

The only structure of fetal gastrointestinal tract (GIT) which is seen on routine second trimester anomaly scan is the fetal stomach. Under normal conditions, the fetal stomach "bubble" is seen on the left side of the fetal abdomen. This is a normal finding on an ultrasound and indicates the stomach's normal position. There are two functions of the fetal GIT: 1. Propulsive action by peristalsis which takes the swallowed amniotic fluid up to the small bowel; 2. Absorption – the amniotic fluid is absorbed through the fetal small bowel. When the stomach is found prenatally to be located on the right side, it is called dextrogastria. Today in our high-risk prenatal clinic, we encountered a patient whose fetus was found to have this rare condition dextrogastria. Is this an isolated issue? What does this mean for clinical outcomes.

Did you know that C-Section birth is referenced in Shakespeare’s Macbeth? Cesarean Section is the most common laparotomy in the world, and yest we are still learning surprising facts about it. This episode we will summarize 2publications which have recently been released. One is from the American Journal of Perinatology (September 2025 ) and the other is from the AJOG (August 2025 ). Does a primary C-section on a laboring uterus have a different risk of PAS in the subsequent pregnancy compared to a non-labored uterus? And what is the percentage of patients who experience “pain” at time of C-section? Listen in for the surprising data. 1.

Just today in clinic, we had a patient, who was well into her third trimester, come to her regular scheduled appointment with new onset left-sided facial droop. Yeah, that’s concerning! A complete history and physical was performed and the diagnosis was made of Bell’s palsy. This is not a rare event and it can be extremely stressful for the affected mother to be because everybody knows facial droop is not normal! And we have recent data regarding this. In July 2025 in the Journal of Plastic, Reconstructive, and Aesthetic Surgery, authors confirmed that Bell’s palsy can have real negative functional and psychosocial implications for those affected. So, in this episode, we are going to discuss Bell’s palsy in pregnancy. How do we differentiate this from the more serious differential, which is a stroke? What about treatment?

Maternal perception of decreased fetal movement at term occurs in up to 15% of pregnancies and is a cause for maternal and provider concern. All maternal concerns of decreased fetal movement require an assessment of fetal wellbeing. But what about the patient with recurrent episodes of reduced fetal movements at term? Routine induction of labor is not supported solely for decreased fetal movement in a non-growth-restricted fetus, as increased intervention rates (including induction of labor and early term birth) have not demonstrated improved perinatal outcomes and may increase neonatal morbidity, such as respiratory distress and NICU admission. Some international sources (ISUOG) have recognized the cerebroplacental ratio (CPR) as a possible ultrasound tool to investigate possible early placental insufficiency before fetal growth restriction occurs. Is CPR helpful for decreased fetal movements at term? A new publication from the Lancet’s new journal- Obstetrcis, Gynecology, and Women’s Health- states that it is. Is the CPR ultrasound assessment recognized by the ACOG or SMFM? Listen in for details. 1. The cerebroplacental ratio: a useful marker but should it be a screening test?

In the 1960s, continuous electronic fetal monitoring was introduced as a way to better capture and document the fetal response to labor and uterine contraction pattern. Since then, it has become a fully integrated component of intrapartum care despite its limited ability to prevent neonatal long term neurological complications and fetal death. We have covered intrapartum fetal heart rate patterns several times on this show, and this episode now VALIDATES those prior episodes. In this episode, we will summarize THREE key points from the October 2025 upcoming ACOG CPG #10 on “Intrapartum Fetal Heart Rate Monitoring: Interpretation and Management”. Is there a place for intermittent fetal auscultation intrapartum? What about maternal O2 for fetal resuscitation? Are we ready for “AI fetal heart racing interpretations”? Listen in for details. 1.

Brain-type natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP) levels originate from the cardiac cells in response to cardiac strain. This may come from a pulmonary embolus, an acute severe infection (sepsis), or cardiomyopathy. But what is the relationship between these 2 cardiac biomarkers and preeclampsia? Can preeclampsia with severe features result in an abnormal rise in these 2 proteins exclusive to heart failure. Listen in to this real case scenario which our on call team cared for. 1.

Stroke (CVA) is very common in women, who have a higher risk than men over their lifetime; one in five women between the ages of 55 and 75 will experience a stroke. Stroke is a significant concern for women's health, being the third leading cause of death and causing more deaths than breast cancer. While systematic estrogen containing menopausal HT has been considered contraindicated in those with prior CVA history, is local/vaginal E2 therapy safe?

According to the J Am Acad Orthop Surg Glob Res Rev. (2024), the incidence of pelvic ring injuries is 34.3 per 100,000 with trauma being the most obvious causation. Women account for approximately 69.7% of these injuries, 23% of which occur in women of childbearing age. In this specific patient population, concern is raised about one's future reproductive capability and method of delivery. The normal bony pelvic movements that occur during vaginal delivery are crucial for accommodating the passage of the fetus through the birth canal; this allows for the normal cardinal phases of labor to occur. These movements involve the widening and shifting of various pelvic joints and bones, primarily influenced by hormonal changes and the mechanical forces exerted by the baby. So, it is reasonable to ask if a patient with pelvic fractures and fixation can safely allow a trial of labor. Is a history of pelvic fractures with surgical fixation an indication for primary cesarean section? If it’s not, in what scenario would a primary c-section be best after a pelvic fracture?

Traditionally, we have learned that any imbalance in the estrogen: progesterone relationship can trigger irregular uterine bleeding. That makes sense, right? During anovulation, prolonged unopposed estrogen can result in HMB. In such a case, we give progesterone as both a therapeutic as well as diagnostic intervention. On the contrary, with progestin only contraception, we consider estrogen predominant products when progesterone breakthrough bleeding (BTB) occurs to restore endometrial stabilization. But a new RCT (AJOG) adds credence to adding MORE progesterone in cases of progesterone associated BTB. Listen in for details. 1. Zigler RE, Madden T, Ashby C, Wan L, McNicholas C.

Routine vaginal examinations (VEs) are a standard component of intrapartum care, traditionally performed at regular intervals to monitor cervical dilation, effacement, and fetal station, which are indicators of labor progression. Yet, the American College of Obstetricians and Gynecologists states that there is insufficient evidence to recommend a specific frequency for cervical examinations during labor, and examinations should be performed as clinically indicated. Now, a recently published RCT form AJOG MFM is adding additional credence to that. Can we space out clinical exams in otherwise “low-risk” laboring women to 8 hours? Listen in for details. 1.
