Descripción

Hyperemesis gravidarum (HG) represents the most severe end of the nausea and vomiting of pregnancy spectrum. It has a reported incidence of approximately 0.3–3% of pregnancies and is the most common cause of hospitalization in early pregnancy and the second most common cause of hospitalization in pregnancy overall. In June 2024, the ACOG published a Clinical Expert series summarizing the inpatient management of HG. In that guidance, it describes mirtazapine as an “alternative pharmacologic” option. How effective is this medication compared to ondansetron? A new study (published ahead of print on 12/30/25 and officially out June 2026), out of Denmark, sheds some new light on this medication. This trial is the first double-blind RCT comparing mirtazapine to ondansetron AND placebo. Although a BIG limitation of this study exists (which we will discuss), it does provide some interesting insights. Listen in for details. 1. (ACOG CES) Clark, Shannon M.

More Steroid Stuff (July 2026)

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.

MOPP & PP BP Control

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 avoidable readmissions. 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 Consensus Decision 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.

Peripartum Cardiomyopathy (PPCM): When the Left Heart Falters

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. 16% OFF TONA ACTIVE WEAR PROMO: https://tonaactive.com/discount/CHAPANOSPINOBG [https://tonaactive.com/discount/CHAPANOSPINOBG] 1. SMFM CS 73; 2025 2.

The “20-minute” Rule for VAVD: 2026 Data

Podcast Family, in this episode we will focus on the “20-minute rule” for vacuum assisted vaginal delivery. This is an important aspect of neonatal safety and is a vital part of procedure documentation. Documentation for vacuum assisted vaginal delivery should include station at application, number of tractions, number of pop-offs and the total traction time and the vacuum trackable time (time from first application to delivery). This has historical roots as well as new data to validate it (March 2026). Listen in for details. 1. ACOG PB 219; 2020 2. Preuss E, Porto A, Sheiman V, Bitton M, Tovbin J, Kedem HI, Barzilay E.

2026 Lp(a), AHA, and OBG: What Now?

The March 2026 ACC/AHA Guideline on the Management of Dyslipidemia made a major pivot regarding Lipoprotein(a) by establishing a formal recommendation for universal screening in adults. This 2026 guideline, published in the Journal of the American College of Cardiology, issued a Class 1 recommendation stating that every adult should have their Lp(a) measured at least once in their lifetime. Because Lp(a) levels are genetically determined and remain highly stable throughout a person's life, a single lifetime check is sufficient for the vast majority of the population to establish their baseline risk. Well, that’s great for Family medicine or internal medicine, but how does that affect us in women’s health? Well, it’s complicated: lipoprotein(a) has been associated with an increased risk of VTE and has also been associated, in some studies, with FGR, preeclampsia, and preterm birth! So, can these patients receive oral contraceptives? What about Perioperative and postop care? Do these patients require anticoagulation? What about pregnancy- is LDA recommended here? And lastly, what about TXA use in patients with HMB? This podcast topic comes from one of our podcast family members who is an OBGYN military personnel caring for our wonderful troops overseas.
