Dr. Chapa’s OBGYN Clinical Pearls

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 sources of information to answer that one). Listen in for details. 1. Gardella, Barbara et al.

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 have fun stuff to review, so listen in!1.

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 benefit ratio. Compared to natural progesterone, synthetic progestins have 10-100- fold greater activity. Synthetic MPA is vasoconstrictive while natural progesterone and drospirenone cause vasodilation and lower blood pressure. Micronized progesterone is bioidentical to the hormone made endogenously and has efficient oral absorption. Progestogens come in oral and transdermal forms, and it can also be given vaginally. Is there data that micronized progesterone is safer for the breast for a menopausal hormone therapy? This podcast topic recommendation comes from one of our podcast family members.

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 Calls for the removal of the black box warning on hormone replacement therapy (HRT) stems primarily from the outdated and limited nature of the data from the Women's Health Initiative (WHI) study published in 2002. The WHI, while groundbreaking at the time, focused predominantly on a specific formulation of conjugated equine estrogens (CEE) and medroxyprogesterone acetate (MPA) in older, postmenopausal women, leading to concerns about its generalizability to the broader population of women considering HRT. This is why on July 17, 2025, the FDA met with a panel of experts, in open forum, to hear the petition of removing the black box warning on hormone replacement therapy. Listen in for details. 1.

Well, I hate to say it, but I'm going to say it: "I Told You So". Back in 2019, we released an episode called "Mycoplasma genitalium: An Overlooked STI". Then, in Sept 2023, we released an episode called, "The Neglected STI", referring to trichomoniasis. Well, on July 22, 2025, a new commentary was released in the AJOG which is making the case why both Trich and MGen SHOULD be reportable STIs, yet they are currently not reportable. Listen in for details and a quick summary/reminder on therapy. 1. https://www.ajog.org/article/S0002-9378(25)00498-3/fulltext2. https://www.cdc.gov/std/treatment-guidelines/trichomoniasis.htm3.https://www.cdc.gov/std/treatment-guidelines/mycoplasmagenitalium.htm

EMDR (Eye Movement Desensitization and Reprocessing) therapy is a recognized and effective treatment for postpartum PTSD, particularly when related to a traumatic birth experience. EMDR helps individuals process traumatic memories and reduce the associated distress, allowing for a more adaptive way of remembering the event. On Aug 4, 2025, a new publication was released in AJOG pertaining to this therapy. What’s this latest randomized controlled trial data saying? Listen in for details.     1.

Edwards syndrome (trisomy 18) affects approximately 1 in 5,000 to 6,000 live births. Patau syndrome (also known as Trisomy 13) is even less common, occurring in about 1 in 8,000 to 12,000 live births. About 20% of cases of Patau syndrome are caused by translocation. On the other hand, approximately 10% of Edwards syndrome cases are caused by a genetic translocation. Both conditions result in a wide range of birth anomalies including the heart, kidneys, and brain as well as cognitive limitations. Both of these conditions are part of maternal cell free fetal DNA testing (NIPTs). Prenatal counseling for expectant parents whose fetus was found to have T13 or T18 once focused exclusively on options for pregnancy termination or postnatal comfort care, on the presumptive basis that all affected infants died. However, examination of contemporary outcomes for these infants suggests that death in the neonatal period is not universal, particularly for infants who receive intensive medical and surgical care after birth. Although severe cognitive and motor impairment and shortened lifespan are anticipated for all survivors, some infants with these disorders live for 1 year or more, and some attain social and interactive milestones, with positive quality of life noted by their caregivers. This has led to newly updated guidance released by the AAP on July 21, 2025. This is a marked shift in counseling for parents of an affected child. Here, we will review what this new guidance is, and what it isn’t.

Delayed (AKA deferred) Cord Clamping (DCC) is extremely beneficial for both the preterm and term neonate. In September 2025, a new Clinical Practice Update (CPU) will be released by the ACOG regarding the amount of time DCC should be done for preterm newborns. This updates data from a Clinical Expert Series which was released in 2022, called “Management of Placental Transfusion to the Neonate”. Is the recommended amount of DCC 30 sec, 45 sec, or at least 60 seconds for preterm newborns? We will highlight this data in this episode. PLUS, we will very quickly summarize a separate yet related publication from JAMA Pediatrics regarding the use of supplemental O2 (100% PP face mask) during DCC for babies born at 22- 28 weeks.

Podcast family, in this episode we will reply to 2 questions raised by our 2 of our podcast family members. The first pertains to a real world, HORRIBLE tragedy of hepatic rupture in pregnancy (no identifiable information released). We will review how and why this happens and what is the single, 5-letter, clinical diagnosis that makes this a possibility. Secondly, we will answer this question: Can MagSo4 ALONE lead to pulmonary edema. The answer is YES. Listen in for details.1. ACOG PB 222;20202.
