What Defines “Refractory” HTN for Preterm sPreE Delivery?

The ACOG PB 222 states, “In women with preeclampsia with severe features at less than 34 0/7 weeks of gestation, with stable maternal and fetal condition, expectant management may be considered”. The expectant management of preeclampsia with severe features before 34 0/7 weeks of gestation is based on strict selection criteria of those appropriate candidates and is best accomplished in a setting with resources appropriate for maternal and neonatal care. BOX 4 in that ACOG guidance lists “Conditions Precluding Expectant management”, with one of the conditions being “Uncontrolled severe-range blood pressures (persistent systolic blood pressure 160 mm Hg or more or diastolic blood pressure 110 mm Hg or more not responsive to antihypertensive medication” (i.,e. persistent and refractory to appropriate medication). But what defines “uncontrolled hypertension”? When is preterm delivery indicated based on that feature? In this episode, we will answer this real-world clinical question. So, for a patient who is otherwise stable, asymptomatic, without HELLP syndrome, whose fetus is stable but is under 34 weeks, when can “uncontrolled hypertension” be diagnosed to prompt delivery? Listen in for details as we highlight the 2022 SMFM Special Report on that matter. 1. ACOG PB 2222.

So, here is a not uncommon situation: A new OB patient presents for initial prenatal care at 28 weeks by “sure LMP” but her ultrasound EGA is just over 3 weeks behind. Simple redating, right? How can we be assured that we are not missing FGR? That is where the “ancillary” use of transcerebellar diameter (TCD) plays a role. In this episode, we will highlight the recent JUNE 2026 data on this and review the 4 scenarios when this supplemental ultrasound finding can play a vital role. 1.

Today we are diving into a topic that is incredibly close to my heart—one that has the potential to fundamentally change how we approach prenatal care and protect pregnant patients. We’re talking about low-dose aspirin for the prevention of hypertensive disorders of pregnancy. Now, if you follow current formal guidelines, you probably know the standard protocol: 81 milligrams a day, prescribed based on specific risk factors. But there’s a growing body of evidence suggesting we might be underdosing—and under-prescribing. What if 162 milligrams taken universally across the board is actually far more effective?In today’s episode, we’re unpacking a brand-new, groundbreaking study published in the American Journal of Obstetrics & Gynecology. And I’m especially excited to cover this one because it comes straight out of my alma mater, Parkland Hospital! This study takes a bold look at real-world outcomes by comparing a period of universal 162-milligram aspirin use directly against a historical period when aspirin wasn’t recommended at all. Did a higher, universal dose significantly cut down on hypertensive disorders? And just as importantly …were there any adverse safety events we need to be aware of? Grab your coffee, settle in, and let's get into the details.1. Duryea E, Ambia A, Pruszynski J. et al. Universal Aspirin Dispensation for Prevention of Preeclampsia in a High-Risk Population.

Today, we are tackling a massive grey area in obstetrics/maternal-fetal medicine: What happens after early fetal growth restriction resolves? When a baby bounces back on the growth chart during the second or third trimester, are they completely out of the woods? Or is there a hidden, lingering risk we aren’t talking about enough? To find out, we’re doing a deep dive into two major publications that dropped just this month, in August 2026 in sister journals (AJOG and AJOG MFM). Both are retrospective, both ask the exact same burning question…and get this: they arrive at completely opposing conclusions. How is that possible? Listen in for details. 1.

The word CERCLAGE comes from the French word, cercle, meaning "hooping" or "encirclement". Cerclage was traditionally reserved for cervical insufficiency but is now a recognized option for patients with a history of preterm birth and a short cervix noted on ultrasound between 16-24 weeks. There are three (3) main indications for obstetrical, cervical cerclage: History-Based, Ultrasound-Based, and Physical- Exam Based. In this episode, we will summarize the key takeaways from the new ACOG CPG on OBSTETRICAL CERCLAGE, being released in September 2026.1. ACOG CPG, Obstertrical Cerclage, Sept 20262.

As of August 20th, 2026, the ACOG has released an updated Clinical Practice Update on opportunistic salpingectomy. Here’s why this matters so much: we now know that the vast majority of high-grade serous epithelial ovarian cancers actually start not in the ovaries, but in the fallopian tubes. By removing those tubes during routine pelvic, obstetric, or even non-gynecologic abdominal surgeries, we aren't just performing standard procedures—we are drastically cutting the lifetime risk of epithelial ovarian cancer by up to 78%. Today, we’re breaking down what’s inside ACOG’s latest guidance, how surgical practices are shifting, and why this simple step is saving lives. Let’s dive in!"1.

ACOG recommends the use of oral or vaginal misoprostol, vaginal dinoprostone (either gel or insert), or mechanical methods for cervical ripening. Plus, it states, “Combination methods (pharmacologic and mechanical) are also effective”. The July 2026 ACOG CPG 9 states this regarding vaginal misoprostol compared to vaginal dinoprostone for labor induction: “Vaginal dinoprostone is effective for cervical ripening; however, vaginal misoprostol has higher efficacy and less need for oxytocin augmentation. The Cochrane database systematic review in 2010 that compared vaginal misoprostol with vaginal dinoprostone in 38 trials (7,022 participants) showed a lower rate of failure to achieve vaginal delivery in 24 hours (RR 0.77) and reduced need for oxytocin augmentation with misoprostol (RR 0.68). There were no differences in the rates of cesarean delivery or tachysystole with FHR changes”. Now, as of August 19, 2026, a new meta-analysis from BJOG is examining this comparison (vaginal miso vs vaginal dino) again. Did they find the same thing? Listen in for details. 1. G. Andersson, B.

Today, we are taking a deep dive into a medical truth thatsounds completely counterintuitive, almost upside down, based on everything you think you know about women's health. But here’s the kicker: it’s actually nothing new at all. For over two decades, ever since the landmark Women’sHealth Initiative (WHI) study made global headlines back in 2002, the blanket narrative surrounding menopausal hormone therapy has been clear and persistent: hormones equal breast cancer risk. But there is a massive asterisk in thatscience that got completely lost in the media noise. While combination therapy with conjugated equine estrogens paired with medroxyprogesterone acetate (CEE +MPA) did show an increased risk, the story for estrogen-only therapy (mainly CEE) in women wh had a hysterectomy is entirely different. In fact, an overwhelming mountain of growing data shows that estrogen-only therapy is protectiveagainst both breast cancer incidence and breast cancer mortality. In this episode, we’re unpacking the latest high-level evidence that cements this crucial distinction. We'll examine the broad statistical landscape, including a comprehensive meta-analysis by Qing et al. (officially set for the December 2026 issue of Annals of Medicine, following its ahead-of-print release in March 2026). Their work breaks down how randomized controlled trial data consistentlypoint to estrogen-only therapy having a protective effect, in stark contrast to combination therapy. We'll also dive into a brand-new Clinical Perspective published in mid-August 2026 in Obstetrics & Gynecology (the Green Journal) by Drs. Andrew Kaunitz and Jason Wright. They call urgent attention to this phenomenon, highlighting RCT meta-analyses that demonstrate a 23% reduction in breast cancer incidence with estrogen alone (RR = 0.77), alongside striking cohort data showing a dramatic risk reduction even in high-risk populations, like carriers of the BRCA mutation.  Listenin for details.1.     Wu Q, Shen L, Hu S, Yang R, Wang Y, Xue D, SunY, Ma H, Dai Z.

Historically, continuous intravenous (IV) insulin infusions were established as the standard of care for pregestational diabetes (Type 1 and Type 2 DM) during labor to prevent acute intrapartum hyperglycemia and minimize the risk of neonatal hypoglycemia. Intravenous insulin offers rapid titration, immediate onset, and a short half-life, allowing precise real-time glycemic control during the physiological stress and fluctuating metabolic demands of labor. Maintaining euglycemia intrapartum is emphasized because elevated maternal blood glucose levels cross the placenta, inducing fetal hyperinsulinemia, which acutely increases the risk of severe post-delivery neonatal hypoglycemia, which can be problematic. Although IV insulin protocols are widely used and are recommended in many practice guidelines, the evidence supporting their superiority over other approaches is limited. Subcutaneous (SC) insulin administration represents a potential alternative strategy to intrapartum glucose management. Continuation of SC insulin, including insulin pump therapy, has been studied most extensively among individuals with type 1 diabetes. However, evidence guiding intrapartum insulin management remains limited for patients with gestational or type 2 diabetes, who represent the majority of pregnancies complicated by diabetes. Institutional protocols frequently default to IV insulin despite limited comparative evidence with SC insulin and the increased workflow burden associated with infusion-based management. Now, a new retrospective study published in SMFM’s PREGANCY journal (25 July 2026; Seattle, Washington) is looking to give routine intrapartum SC insulin some validity. What did the data show?

Urge urinary incontinence (UUI) places a significant emotional and physical burden on women affected. Sacral neuromodulation has been and remains a well-established implant-based therapy for UUI. The concept originated in the early 1970s from sacral anterior root stimulation research for neurogenic bladder, with human clinical trials beginning in 1982. Medtronic's InterStim device received FDA approval in 1997 for UUI, and in 1999 for urgency-frequency and nonobstructive urinary retention. This was a game changer for affected women. Now, as of August 5, 2026, the FDA has granted 510(k) clearance for a new, less invasive neuromodulation implant- placed in the ANKLE. This is the Revi Extend Implant system (BlueWind Medical). What was the phase 3 data on this? What does the “wearable controller device” look like? Listen in for details. 1. Lukacz ES, Santiago-Lastra Y, Albo ME, Brubaker L.
