Podcast family, welcome to Quickie #4. This one will be fun: A. Medicine changes, and changes fast. I trained with and learned the Grannum grading placental system (grades 0-III based on ultrasound appearance). Is that still a thing? We recently found a “grade III placenta at 34 weeks” as an incidental finding. Is there specific management considerations for this? Listen in for details. B. What do we do when a patient has “two GBS results” in one pregnancy hat are discordant. Listen in for that as

The Problem of Proving Pregnancy too Promptly

Dr. Chapa’s OBGYN Clinical Pearls ·

2026/03/22

Well, it's no doubt we live in a culture of immediate gratification. When we need to know something, we must know it immediately! This even applies to couples seeking pregnancy and their desire to find out if their monthly attempts have been successful. However, there is a problem with trying to prove pregnancy too promptly. In this episode, we will review a new publication just released on March 1st, 2026 out of the Green journal. These authors evaluated a prospective cohort (PRESTO cohort) of

Podcast family we've all heard the rumors that oursmartphones are “LISTENING TO US”. Well, some of that is actually true, and trust me I'm not a conspiracy theorist. Our smartphones are capable of remarkable things. A new publication from the Green journal (released ahead ofprint on 03/05/2026 ) is proposing that it may now be able to detect fetal movement, fetal breathing, and even fetal hiccups when placed over the abdomen!

What’s Best Analgesia for ECV?

Dr. Chapa’s OBGYN Clinical Pearls ·

2026/03/16

Neuraxial analgesia (epidural or spinal) combined withtocolytic therapy is the pain control method that best increases the success rate of external cephalic version (ECV), according to the ACOG’s PB 221. However, some patients may be reluctant to use regional anesthesia and may askabout IV analgesia. A new study in the AJOG (released as an ePub on March 5, 2026) provides some insights that may be helpful for patient consultation. These investigators compared the success of external cephalic version,

The ACOG 2025 guideline specifically recommends either oral or vaginal misoprostol for cervical ripening; it does not include buccal administration among its endorsed routes. With the rising rates of both obesity and labor induction, understanding the optimal agents for induction in obese patients is crucial. In a new study released ahead of print on March 4, 2026, in the AJOG, investigators from Indianapolis released findings from a secondary analysis of the IMPROVE trial (2019, AJOG) looking at

Best ZMax Regimen for PPROM?

2026/03/08

For preterm prelabor rupture of membranes, the standard protocol for latency augmentation has remained IV amoxicillin and erythromycin for 2 days, followed by oral amoxicillin and erythromycin for 5 additional days. Nonetheless, azithromycinhas largely replaced erythromycin in PPROM management due to supply shortages and tolerability. Previous retrospective studies (2019) have found no difference in latency between single-dose and multi-day azithromycin regimens, but these studies did not measure

Can Oral Probiotics Reduce recurrent sPTB?

Probiotics. They are often marketed as the end of all and be all for all our health issues. And they CAN do some real good. There is NO DOUBT a connection with overall heath and gut health…and NO ONE can deny that. But probiotics gets grey for some women’s health issues. A new prospective, single-arm, non-blinded, multicenter study across 31 hospitals in Japan is making some pretty dramatic claims regarding oral probiotics and recurrent spontaneous preterm birth (ePUB).

Believe in Bed Rest for PTB? The AWARE Study

Dr. Chapa’s OBGYN Clinical Pearls ·

2026/03/02

Neither the ACOG nor SMFM recommend strict bed rest for preterm birth prevention, or nor preeclampsia. Yet tradition often conflicts with evidence. A prior 2009 survey of MFM specialists, published in the AJOG, on the use of bed rest revealed that 71% used activity restriction in their practice for arrested preterm labor, despite the majority believing it had minimal or no benefit. The authors concluded, “Because most obstetricians in our survey indicated they would prescribe bed rest believing it

Pregnancy and the Brain

A study published in Nature Communications, published Feb 19, 2026, found that “pregnancy physically alters a woman’s brain, with a second pregnancy bringing even more profound effects.” The researchers “performed brain scans on 110 women. Some were first-time mothers, others second-time moms, and some nulliparous women. Results showed that during a first pregnancy, the greatest changes occur in the structure and activity of the ‘default mode network’ – the brain system responsible for

Hyst + BSO for BRCA Risk Reduction?

Dr. Chapa’s OBGYN Clinical Pearls ·

2026/02/24

Approximately 5–10% of all breast cancers are hereditary, and among those, BRCA1 and BRCA2 mutations are responsible for about 60% of cases. Yet, overall, only about 1-2% of all breast cancers in the general population are caused by BRCA mutations. Once childbearing is complete, the NCCN recommends risk-reducing BSO in patients carrying these mutations. But what about the uterus? Since childbearing is complete, and the ovaries are now removed, the sole purpose of the uterus- which is to initiate,

New Data: Screen Maternal Ferritin with Prenatal Care?

The ACOG states that, “Iron deficiency anemia during pregnancy has been associated with an increased risk of low birth weight, preterm delivery, and perinatal mortality and should be treated with iron supplementation in addition to prenatal vitamins. In addition, there may be an association between maternal iron deficiency anemia and postpartum depression, with poor results in mental and psychomotor performance testing in offspring”. Screening for anemia is included in most prenatal lab sets

Alex’s Input: Aspirin’s Awkward Acumen

2026/02/18

We recently covered an SMFM abstract that was presented at the annual Pregnancy Meeting held in early February 2026. The authors were from my Alma Mater, UT Southwestern/Parkland Hospital. This was a well-done study comparing 162 milligrams aspirin to 81 milligrams of aspirin. The results were very encouraging! However, aspirin definitely has an awkward acumen. It would be wonderful if ALL the data just leaned in the same direction... but it doesn’t! Enter our podcast family member, and my friend

More Support for 162mg LDA Universal Use in OB

2026/02/16

Well, even though low dose aspirin has been recommended for the reduction of preeclampsia risk for many years, 2 controversies persist: 1. who should get it, and 2. the dose we should use. While the current US recommendation still focuses on 81 mg low dose aspirin, initiated after 12 weeks of gestation (based on risk factors), there's increased movement and growing data supporting both universal adoption and the higher dose of 162 mg. In this episode, we will briefly summarize brand new data out

GDM vs “Early” GDM vs PrePreg DM: A Proposal

2026/02/13

As BMIs and weights increase across the US population, there have been increased calls for universal screening for existing DM at entrance to prenatal care, if under 20 weeks. Others, including the ACOG, prefer to screen early those with additional risk factors (like prior GDM HX, prior macrosomia, BMI >30, PCOS, first degree relative with diabetes, or age >40). In July 2024, the ACOG released its publication, “Screening for Gestational and Pregestational Diabetes in Pregnancy and Postpartum”

There has been a shift in cervical cancer screening from primary cytology based to HPV based. Even HPV screening has had its evolution from physician collected samples to patient self-collection, either in a clinical setting or at home with an approved collection system. In May 2025, the FDA cleared the first at-home self-collection kit for HPV screening, specifically the Teal Wand by Teal Health. Now, we are seeing the advent of POSSIBLY another avenue for cervical HPV testing- although it is a bit

Well podcast family, we are back with another installment of our “You ask, We answer” edition. We've got 2 fascinating and real-world clinical conundrums in this episode, both suggested by two separate podcast family members. The first has to do with RH IG maternal administration. Here's the question: If a patient receives routine, prophylactic RH IG at 28 weeks but then has maternal trauma say 1 or 2 weeks after, does she still require an additional dose of RH IG? That's a good question

Understanding Fetal Microcephaly

Dr. Chapa’s OBGYN Clinical Pearls ·

2026/02/05

Fetal Microcephaly has an incidence of 2 to 12 in10,000 births in the USA and can be diagnosed prenatally via ultrasound (in second or early third trimester) or postnatally via measurement of head circumference (HC). Antepartum, this is a unique diagnosis since we are mainly used to using PERCENTAGES for biometrics and for fetal weight, butmicrocephaly is not diagnosed by HC percentage- but by Standard Deviation (SD). Microcephaly has been linked to developmental delay, seizures, as well as
