Dr. Chapa’s OBGYN Clinical Pearls

On October 9, 2025, the ACOG released a clinical practice update (CPU) regarding Zouranolone and brexanolone. As postpartum depression is an area of continued research and need for therapeutics, any new clinical practice update on the subject is welcome. So what's new in this update?! Well…the answer will surprise you. Listen in for details on the CPU, and a mini-review of the concerns for Zur...

Sometimes you hear something that makes you just stop and say, “What did you say?!”. Yep, in this episode we will give evidence-based answers to three questions that I heard TODAY that made me stop and ask, “What did you say?”. In this episode we will cover: 1. Umbilical cord blood collection from a monochorionic twin gestation, 2. Predictability of the mBPP compared to full BPP, and 3. Breastfeed...

In July 2023, the ACOG released a Practice Advisory stating, “Based on data on the benefit of adjunct HPV vaccination, ACOG recommends adherence to the current Centers for Disease Control and Prevention (CDC) recommendations for vaccinations of individuals aged 9–26 years, and to consider adjuvant HPV vaccination for immunocompetent previously unvaccinated people aged 27–45 years who are undergoin...

FYI

A breakthrough discovery in the 1970s was the determination of alpha-fetoprotein levels in the serum of pregnant women to detect fetuses with neural tube defects. In the case of high AFP values in maternal serum, amniocentesis was performed to determine the levels of AFP and acetylcholinesterase (AChE) in the amniotic fluid to confirm the diagnosis. Currently, the ACOG states that high-quality, se...

The only structure of fetal gastrointestinal tract (GIT) which is seen on routine second trimester anomaly scan is the fetal stomach. Under normal conditions, the fetal stomach "bubble" is seen on the left side of the fetal abdomen. This is a normal finding on an ultrasound and indicates the stomach's normal position. There are two functions of the fetal GIT: 1. Propulsive action by...

Did you know that C-Section birth is referenced in Shakespeare’s Macbeth? Cesarean Section is the most common laparotomy in the world, and yest we are still learning surprising facts about it. This episode we will summarize 2publications which have recently been released. One is from the American Journal of Perinatology (September 2025 ) and the other is from the AJOG (August 2025 ). Does a primar...

Just today in clinic, we had a patient, who was well into her third trimester, come to her regular scheduled appointment with new onset left-sided facial droop. Yeah, that’s concerning! A complete history and physical was performed and the diagnosis was made of Bell’s palsy. This is not a rare event and it can be extremely stressful for the affected mother to be because everybody knows facial droo...

Maternal perception of decreased fetal movement at term occurs in up to 15% of pregnancies and is a cause for maternal and provider concern. All maternal concerns of decreased fetal movement require an assessment of fetal wellbeing. But what about the patient with recurrent episodes of reduced fetal movements at term? Routine induction of labor is not supported solely for decreased fetal movement...

In the 1960s, continuous electronic fetal monitoring was introduced as a way to better capture and document the fetal response to labor and uterine contraction pattern. Since then, it has become a fully integrated component of intrapartum care despite its limited ability to prevent neonatal long term neurological complications and fetal death. We have covered intrapartum fetal heart rate patterns...

In 2023, we released 2 episodes on obstructive sleep apnea (OSA) and adverse pregnancy. Now, on September 16, 2025, a new publication from JAMA Network Open adds more insights to disturbed sleep and adverse pregnancy outcomes. How does insomnia affect pregnancy? And is there any data on night shift work and its altered circadian rhythms on adverse pregnancy outcomes? Listen in for details. 1. Ross...

Brain-type natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP) levels originate from the cardiac cells in response to cardiac strain. This may come from a pulmonary embolus, an acute severe infection (sepsis), or cardiomyopathy. But what is the relationship between these 2 cardiac biomarkers and preeclampsia? Can preeclampsia with severe features result in an abnormal rise in these 2 prote...

Stroke (CVA) is very common in women, who have a higher risk than men over their lifetime; one in five women between the ages of 55 and 75 will experience a stroke. Stroke is a significant concern for women's health, being the third leading cause of death and causing more deaths than breast cancer. While systematic estrogen containing menopausal HT has been considered contraindicated in those...

Mastalgia is a common breast complaint in reproductive aged women. Mastalgia can be separated into three categories: 1) cyclical, 2) noncyclical, and 3) extramammary. Vitamin B6 is often cited as a homeopathic (non-prescription/pharmacological) remedy for simple mastalgia. Does the published data support its use? A newly published meta-analysis sheds light on the subject. 1. Sharifipour, F., Siahk...

We are delaying today's program, as stated in this message. We will resume our program as soon as possible. Remembering Charlie Kirk.

We have a wonderful podacst community! Within 24 hours of our immediate past episode release, one close friend- and fellow OBGYN, Dr. Eric Colton (OB Hospitalist Group) reached out and shared valuable words of wisdom regarding a potentially deadly complication of the CS-scar defect...the CS scar ectopic pregnancy. Listen in for Dr. Colton's cameo and details. 1. Ban, Yanli MD, PhD; Shen, Jia MD; W...

On Sept 10, 2023, er released an episode titled, “CS Ut Closure: Decidua or No Decidua?”. We highlighted the importance of AVOIDING the decidua at hysterotomy closure at CS. Now, in Sept 2025, in Obstetrics and Gynecology (the Green Journal), there is a new systematic review and meta-analysis on this very topic. Does this new study CONFIRM or REFUTE what we explained 2 years ago? Listen in for det...

According to the J Am Acad Orthop Surg Glob Res Rev. (2024), the incidence of pelvic ring injuries is 34.3 per 100,000 with trauma being the most obvious causation. Women account for approximately 69.7% of these injuries, 23% of which occur in women of childbearing age. In this specific patient population, concern is raised about one's future reproductive capability and method of delivery. The...

Traditionally, we have learned that any imbalance in the estrogen: progesterone relationship can trigger irregular uterine bleeding. That makes sense, right? During anovulation, prolonged unopposed estrogen can result in HMB. In such a case, we give progesterone as both a therapeutic as well as diagnostic intervention. On the contrary, with progestin only contraception, we consider estrogen predom...

Routine vaginal examinations (VEs) are a standard component of intrapartum care, traditionally performed at regular intervals to monitor cervical dilation, effacement, and fetal station, which are indicators of labor progression. Yet, the American College of Obstetricians and Gynecologists states that there is insufficient evidence to recommend a specific frequency for cervical examinations during...

Breast cancer is an hormone responsive malignancy, meaning it may use estrogen and progesterone, reduced in high quantities during a pregnancy, for growth. However, as medical evidence evolves quickly, physicians have come to understand that breast cancer diagnosis during pregnancy doesn't always mean worse prognoses. While older studies- including meta analysis-reflected worse prognoses for p...

YEP…Its another episode of You Asked, We Answered! In this episode, we will look at the data to answer 2 questions that came into the show within the last 24 hrs: 1. Is oral or topical therapy best for first treatment of uncomplicated vulvovaginal candidiasis? (We have new data- AJOG, Sept 2025, to answer that), and 2. Is urine PCR testing for UTI diagnosis a “routine practice”? (We will look at 4...

In the last 2 episodes we covered new updates in menopausal hormone therapy. However, we did not address TESTOSTERONE use. This episode idea comes from one our podcast family members and good friend, Eric. Eric is 100% correct: Testosterone replacement, when done correctly, has come along way. When is this indicated? Is this endorsed by professional medical/endocrine groups? What’s the dose? We ha...

This is a requested follow up to our most recent episode. Menopausal hormone therapy (HT) prescribing practices have evolved over the last few decades guided by the changing understanding of the treatment’s risks and benefits. We know that dose, route of administration, and choice of agent (estradiol versus a more synthetic option, and micronized progesterone over other progestins.) alter the risk...

There’s a lot of fear and misinformation around HRT, and one of the biggest myths is that HT is a highly significant cause of breast cancer. That is not the case. This is a remnant concept from 2002, with MANY caveats. Calls for the removal of the black box warning on hormone replacement therapy (HRT) stems primarily from the outdated and limited nature of the data from the Women's Health Init...
