SHOCKING: ACSs INCREASE Risk in Twins? (Listen in)

Dr. Chapa’s OBGYN Clinical Pearls ·

2026/06/08

In the ACOG PB 231, Multifetal Gestations Twin Triplet and Higher-Order Multifetal Pregnancies, it states, “based on the improved outcomes reported in singleton gestations, the National Institutes of Health recommends that, unless a contraindication exists, a course of antenatal corticosteroids should be administered to all patients who are at risk of delivery within 7 days and who are between 24 weeks and 34 weeks of gestation, irrespective of the fetal number”. But a BRAND NEW meta-analysis is

5mm v 1-cm Fascial Closure at CS: MINI EPISODE

Dr. Chapa’s OBGYN Clinical Pearls ·

2026/06/06

Historically we were taught as surgeons that 1-centimeter bites that between suture throws on a Pfannenstiel (low transverse) fascial closure was enough to prevent hernia formation and optimize facial healing. But is this still evidence based? We can extrapolate data from a May 2026 systematicreview/meta-anlysis as well as a separate study from the Dutch published in 2021. Both of these studies were in the journal Hernia. The evidence does favor one technique over the other! Listen in for

Dr. Chapa’s OBGYN Clinical Pearls ·

2026/06/05

Today, we are talking about a true paradigm shift in prenatal genetics. For decades, we’ve relied on cell-free DNA for screening, but when it came to definitive confirmation of fetal aneuploidy, we’ve had to counsel our patients through the anxiety and physical risks of invasive procedures like amniocentesis and CVS. But what if the line between screening and confirmation just blurred? In this episode, we are diving into an avant-garde, first-of-its-kind maternal blood test that is now actively in

OB, ED, and STDs: Gaps Noted!

Dr. Chapa’s OBGYN Clinical Pearls ·

2026/06/03

Back in June 2024, we highlighted surprising data from JAMA Network Open regarding adolescent care in the ED. Because many adolescents use the ED as their primary care provider, it’s a good opportunity for them to have contraception addressed regardless of why they presented. But that’s not what was happening. That publication from two years ago showed significant gaps in addressing contraception in the ED to pregnancy vulnerable young women, mainly teens. We covered those results back then and said

Treat Non-Severe PreE with BP Meds?

2026/05/31

Welcome back, everyone. Today we're diving into one of the most hotly debated topics in obstetrics- should we be treating preeclampsia without severe features with antihypertensive medications during expectant management? Now, if you've been following the literature- and our show, you know that the landmark CHAP trial changed the game for chronic hypertension in pregnancy. It showed us that targeting a blood pressure below 140 over 90 reduces serious maternal complications, without harming

The WILDCARD: LUS Window on Prenatal Sono, TOLAC?

Dr. Chapa’s OBGYN Clinical Pearls ·

2026/05/28

The American College of Obstetricians and Gynecologists (ACOG) does not recommend routine ultrasound measurement of the lower uterine segment (LUS) thickness as part of the evaluation for trial of labor after cesarean delivery (TOLAC). ACOG Practice Bulletin No. 205 (2019) on Vaginal Birth After Cesarean Delivery does not include LUS measurement among its recommendations for TOLAC candidacy assessment. The guideline focuses on clinical factors such as type of prior uterine incision, number of prior

Home Self-Check Urine Protein for gHTN?

Should patients check their own urine protein at home when they have a gestational hypertension DX? After all, home-based BP monitoring is an established part of HDP care. Is there data on home urine protein dipstick tests in gestational hypertension? What do professional guidelines say? And what are the pros and cons of home self-monitoring of urine protein?

Is OB HPBM “Evidence-Based”? BUMP1&2 vs SMFM Special...

Dr. Chapa’s OBGYN Clinical Pearls ·

2026/05/24

The vast majority of the time, “community standard of care” reflects evidence-based recommendations. This means that both the predominance of clinical data and what is clinically practice align one with another period but at times, clinical standard practice doesn't always align with what the data shows. How is this possible? This is exactly the case for home blood pressure monitoring in pregnancy (HBPM). This episode idea comes from an OB PGY-3, soon PGY-4, who asked his attending this

Patient Self-Titration of Insulin for GDM?

Dr. Chapa’s OBGYN Clinical Pearls ·

2026/05/21

Outside of pregnancy, guidelines emphasize diabetes self-management education and support to facilitate informed decision making, self-care behaviors, problem solving, and active collaboration with health care professionals. This includes, in those with good health literacy, the concept of patient-led self-titration of basal insulin results which has data that it improves glycemic management compared with clinician-led titration for type 2 diabetes among nonpregnant adults. But what about for GDM

VOMIT Trial: Mirtazapine vs Ondansetron for HG

Dr. Chapa’s OBGYN Clinical Pearls ·

2026/05/18

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

The “Half-Cm” Cervical Exam: Is that a thing? (With...

Dr. Chapa’s OBGYN Clinical Pearls ·

2026/05/15

Cervical exams can be tricky for the novice practitioner. Think about this: it’s a blind exam, we measure that distance using only two fingers, through a layer of tissue, sometimes with a patient moving up on the bed as we examine. That is the reality of a cervical exam. Intrapartum, some nursing staff and clinicians use qualitative descriptors like "a tight 4" or "a generous 5" to convey nuance. In line with this, some report cervical examinations in “half- centimeters”. This

Oh, What’s in a Name? Irving F. Stein and Michael L. Leventhal first described the syndrome, originally known as Stein-Leventhal syndrome, in 1935, in the AJOG. They published a case series of seven women displaying a triad of symptoms, including hirsutism, amenorrhea (absent menstruation), and bilaterally enlarged polycystic ovaries. We now know that PCOS affects 1 in 8 women globally (170 million women of reproductive age worldwide), and that there are 4 main manifestations of the condition-

Hantavirus & Pregancy FAQ

Dr. Chapa’s OBGYN Clinical Pearls ·

2026/05/11

Hantavirus was first discovered in the early 1950s near the Hantaan River in South Korea. The US has seen this before: the 1993 Four Corners outbreak was the first recognition of the virus in the United States, causing a deadly respiratory syndrome. Now, Hantavirus is in the news again with 17 Americans currently (5.10.26) enroute back to the US for specialized observation. In this episode, we will briefly review what this virus does and cover the SPARSE data we have regarding hantavirus infection

Do Unintended Uterine Extensions Increase Rupture?

Uterine hysterotomy unintended extensions happen. For sure. This has been analyzed over many years, and it is still making news. Look at this mini-timeline: Back in 2018, authors published “Unintended hysterotomy extension during caesarean delivery: risk factors and maternal morbidity”. Moving up the timeline to 2020, others published in J Maternal-Fetal Neonatal Medicine, “Risk factors for uterine incision extension during cesarean delivery”. Then in 2024, in the PINK journal, authors published a

Weird cfDNA Results and ISSUES: May 2026 Data

Genome-wide noninvasive prenatal testing (GW-NIPT) was introduced in 2015 and became widely available in 2019. Nonetheless, we are still learning more about this important prenatal screening test. In January 2026, the ACOG released a new PA on this, which we will also review in this episode. Our main publication ti review, however, will be the AJOG May 2026’s systematic review and meta-analysis on the finding of “genome-wide” cfDNA discordant results and what this may mean for the pregnancy

GLP1 Periconception Exposure and OB Outcomes

2026/05/04

There is no denying it, you know of one or MORE individuals or patients currently on a GLP1 agent. Although not FDA approved for PCOS as a stand-alone diagnosis, there is growing evidence supporting their offlabel use in PCOS, and international guidelines now include them as a conditional recommendation. In women, the weight loss associated with these medications may trigger the return of spontaneous ovulation, making mistimed pregnancy a possibility. A key study by Sanz and Blázquez (back in 2011)

HG: IVFs, Dextrose, & Ketones? (Lancet, 2026)

Dr. Chapa’s OBGYN Clinical Pearls ·

2026/05/01

The belief that IV dextrose is necessary to clear ketones in hyperemesis gravidarum originated from a logical, and now known to be outdated, extrapolation of basic starvation ketosis physiology and the treatment paradigm for diabetic ketoacidosis (DKA). The original experiments that led to this conclusion go back to the 1960s (Foster data). Not only is this outdated, but it is also physiologically incorrect. We’ve learned a lot about IV fluid replacement about hyperemesis gravidarum in the last
