New CPG on OB CERCLAGE (Sept 2026)

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…

New CPU on OPS!

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…

Vag Miso vs Vag Dino: New Meta-analysis (Aug 2026)

ACOG recommends the use of oral or vaginal misoprostol, vaginal dinoprostone (either gel or insert), or mechanical methods for cervical ripening.

Estrogen’s Protection Against Breast CA: The Underappreciated Data

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…

SC v IV Insulin Intrapartum

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…

Intro to REVI EXTEND IMPLANT (Not a sponsor)

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…

The QBL Paradox: Precision vs. Performance in OB Hemorrhage

Today, we are taking a deep dive into an intervention that almost every labor and delivery unit in North America has adopted over the last decade: Quantitative Blood Loss, or QBL. ACOG first recommended quantitative blood loss assessment in Committee Opinion Number 794, published in December 2019. This opinion recommended that every birthing facility implement a standardized, quantitative method…

Routine US for RPOC After 2nd Trimester Loss?

Today, we’re stepping into one of the most clinicallydelicate and emotionally heavy scenarios you can encounter in women's healthcare: a mid-pregnancy loss, say right around that 18 to 20-week mark. It’s a situation where the clinical room feels still, the emotional weight is immense, and every decision you make as a clinician carries profound gravity. Picture the scenario: The delivery has…

A Mechanic’s Vision: The OdonAssist™ Device (Not Ready for US Approval)

Today, I want to tell you a story that sounds like it was completely made up for a movie script, but it’s 100% real. Imagine an automotive mechanic in Argentina. He has zero medical training, no background in obstetrics, and no clinical degree. One night, he sees a simple party trick on YouTube: how to get a lost cork out of the inside of an empty wine bottle using nothing more than an inflated…

ACOG first recommended antiviral suppressive therapy at 36 weeks of gestation for women with a history of genital herpes in 2007, with the publication of Practice Bulletin No. 82 ("Management of Herpes in Pregnancy," June 2007). This was the first ACOG practice bulletin specifically dedicated to genital herpes management in pregnancy, and it established the 36-week suppressive therapy…

Now, if you’ve been practicing or following clinical guidelines for a while, you know the frustrating backstory here. For years, the standard advice was simple: "Just take 800 milligrams of ibuprofen an hour…

Now, Listen. It is completely natural to see a specialist standing in a white coat making a passionate claim…

Rescue ACS with PPROM?

Antenatal corticosteroids are a MAJOR win in the management of preterm labor. An initial course of antenatal corticosteroids has been shown to reduce morbidity and mortality in patients with preterm prelabor rupture of membranes. For patients who remain undelivered after the initial course of antenatal corticosteroids, it is uncertain whether a booster course of antenatal corticosteroids reduces…
