The Cerebellum (TCD) as EGA Referee (opens the original)
Read excerpt
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. Fetal Trans
Parkland Universal LDA (162mg) Preg Study (opens the original)
Read excerpt
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 underdosi
“Resolved” Early FGR: Now What? (opens the original)
Read excerpt
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 retrospec
New CPG on OB CERCLAGE (Sept 2026) (opens the original)
Read excerpt
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
New CPU on OPS! (opens the original)
Read excerpt
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 epithelia
