Dr. Chapa’s OBGYN Clinical Pearls

In 2018, the ARIVE trial was published in the NEJM revealingthat induction of labor at 39 weeks reduced cesarean deliveries and gestational hypertension/preeclampsia in low-risk nulliparous women who had labor induced,compared to expectant management. Then, in 2025, and partly in response to L&D units across the country becoming saturated with low- risk, nulliparous patients awaiting their induction of labors at 39 weeks and 0 days, the ACOGreleased its clinical practice update in Jan 2025 stating, “The optimal timing of delivery for full-term pregnancies (39 0/7 to 40 6/7 weeks of gestation has not been determined”. Now there is new data, released as an article in press(June 26, 2026), out of the AJOG that raises some interesting questions about potential benefits of induction of labor LATER in the “full term” interval (40- 40 and 6 days) compared to earlier full term (39 weeks to 39 weeks 6 days). Thesefindings are “hypothesis- generating”.  Listen in for details.

If you practice obstetrics, you already know that our entire world is ruled by a stopwatch. Think about it: we are obsessed with time. We wait exactly 60 or 120 minutes for a gestational diabetes challenge. We stare at a monitor for a strict 30 minutes timing a biophysical profile. The entire pregnancy is dictated by an Estimated Date of Delivery that has us counting down the literal days. But what happens when we step into the OR? Once that scalpel hits the skin for a cesarean section, does the clock matter just as much? There are two separate intervals which have generated data: the skin incision to delivery interval, and the uterine incision to delivery interval. In today's episode, we are CUTTING INTO the data. First, we are summarizing a hot-off-the-press study from AJOG-MFM (Pink) that takes a hard look at the macro clock—the skin incision-to-delivery interval. Then, we are going to contrast those findings with the recent Bart 2026 study published in the AJOG (Grey) Journal, which tracked over 5,800 routine deliveries to see exactly what happens to a baby's pH and clinical outcome when that uterine extraction takes longer than 120 seconds. These two are somewhat at odds. Listen in for details.

Think about the last time you had to time something perfectly. Maybe it taking that perfect swing at the baseball, or catching a flight after a commute, or making a high-stakes decision. In the world of high-risk pregnancy, clinicians play a constant game of high-stakes timing with a usual medication called antenatal corticosteroids. Given to moms at risk of giving birth early, these steroids are a gamechanger for a preterm neonate. But there’s a catch. If you give them too early, the benefits fade. If you give them too late and she delivers very quickly, they don't have time to work. A brand-new study published in the journal Obstetrics & Gynecology by Mark Clapp et al reveals just how incredibly difficult this balancing act is. This data shows that nearly 26% of pregnant individuals who received these steroids actually went on to deliver completely full-term, exposing babies to medications they might not have needed. So how do we as clinicians solve this OB Goldilocks problem where the stakes are a newborn baby's health? On today's episode, we break down the data behind 'maximizing benefit while avoiding overuse' and what it means for real world practice.

More than 60% of maternal deaths occur during the postpartum period, and hypertensive disorders of pregnancy are a major, preventable driver of that statistic. For too long, the transition from labor and delivery to home has been a vulnerable blind spot—leading to high rates of avoidablereadmissions. But the landscape has shifting. In this episode, we are diving deep into why OB providers must optimize blood pressure control before and after postpartum discharge. We’ll be breaking down the landmark 2025 MOPP study, which shook up our traditional targets by examining tight versus standard blood pressure control, alongside the recently released May 2026 ACC Expert ConsensusDecision Pathway.What is the actual "goal BP" for a safe postpartum discharge? When should we initiate outpatient tight control, and how do we prevent these patients from bouncing back to the ED? Grab your coffee and pull up a chair. Let’s look at the evidence.

Welcome back to the show, everybody! Today, we are diving deep into the intersection of maternal-fetal medicine and cardiology. We’re tackling a condition that keeps every OB/GYN, MFM, and cardiologist up at night: Peripartum Cardiomyopathy, or PPCM. And to keep our clinical gears turning, we are framing this discussion squarely through the lens of Society for Maternal-Fetal Medicine (SMFM) Consult Series #73, which focuses on right and left heart failure in pregnancy, alongside the foundational data from ACOG Practice Bulletin #212. PPCM presents fundamentally as acute left heart failure with reduced ejection fraction. Think of the left ventricle as the primary engine pump of the systemic circulation. When it stalls, everything upstream gets backed up. While this was traditionally called IDIOPATHIC, newer data says otherwise. We are going to cover presentation, eval, care and prognosis. So, get your palpitations in check- here we go.
