Dr. Chapa’s OBGYN Clinical Pearls

Delayed cord clamp is standard of care. On today’s episode, we are stepping into a high-pressure dilemma in the labor and delivery room. Imagine this (which doesn’t need a lot of imagination, because it is a real event which occurred to one of our podcast family members): A mother has carefully drafted a birth plan. One of her non-negotiable requests is delayed cord clamping for two full minutes. But the moment the baby is delivered, it becomes clear that the infant is non-vigorous: floppy, pale, and not breathing. The baby urgently needs immediate resuscitation.
The physician reaches for the cord shears, but the mother demands: "No! Wait the two minutes! It's my decision!" What happens next? Whose rights win out? Today, we’re exploring clinical guidelines, the core ethical principles, the legal mandates, and state FOUR established norms that govern the delivering professional’s actions.

Here is a sobering fact: Iron deficiency is one of the most common health conditions in the world. Iron deficiency affects an estimated one in three people, yet many go undiagnosed and untreated despite widespread treatment options. Iron deficiency can progress to iron deficiency anemia. If you’ve been listening for a while, you know we have banged the drum on this podcast time and time again about why serum ferritin matters. We’ve talked about how so many people suffer from low iron stores even when their basic blood work comes back looking "normal," and why we have to look way beyond just standard iron deficiency anemia. Well, guess what? The medical establishment is officially catching up! In September 2026, the American Society of Hematology (ASH) released brand new, evidence-based recommendations that are set to completely change how we diagnose iron deficiency. Published in ASH’s prestigious, peer-reviewed journal Blood Advances, these new guidelines were brought together by a multidisciplinary team of experts across multiple medical specialties to redefine critical thresholds- especially for women and during pregnancy. Today, we are diving deep into what these new guidelines actually mean for us. Listen in for details

Innie vs Outies: no, we are not referring to bellybuttons. In this episode, we’re talking about the labia of the Volva! Does it actually matter? Which one is more common? Now, this episode was actually sparked by a brilliant listener who sent us her question to our IG inbox (as a non-clinician): “Can having an innie labia actually cause me to have recurrent bacterial vaginosis?” Such a good question, right? So today, we’re going to break down what the medical literature actually says about anatomy and BV. Plus, well answer the question: What is ACOG’s stance on elective labioplasty? Grab a cup of coffee, get comfortable, and let’s normalize the normal.

Marfan syndrome is an autosomal dominant, connective tissue disorder. Because it’s autosomal dominant, an affected parent has a 50% chance of passing the genetic mutation to their offspring in every pregnancy. Approximately 25% of cases actually stem from spontaneous, de novo mutations with no prior family history. In the United States, the prevalence of Marfan syndrome is estimated at roughly 1 in 5,000 individuals. It affects males and females equally across all ethnic backgrounds. Although this topic and condition might sound rare at first glance- Marfan syndrome in pregnancy- it is in our communities, and we need to be ready for the potential complications that come with it. When is vaginal delivery allowable here? Do these patients need any maintenance meds during pregnancy? What about postpartum surveillance? Grab your coffee, get comfortable, and let's jump right in!

If you’ve ever managed postpartum preeclampsia, you know the clinical gray zone: after an initial intrapartum course of magnesium sulfate, when do you actually restart it for a postpartum, readmission exacerbation? Always? There’s no standard national guidance on this. Every unit seems to do something a little different. In this episode, we’re summarizing a new study looking at practice patterns across the country. This study is actually a survey of US MFM fellowship directors across the ACOG Districts. This publication will be officiallyreleased/published in the Journal of Maternal-Fetal and Neonatal Medicine in December 2026. We’ll break down what these fellowship directors would do, why the variation exists, and what this means for your clinical practice. Let’sget into it.
