Dr. Chapa’s OBGYN Clinical Pearls

Artificial Intelligence (AI) has arrived. Machine Learning is a form of AI which is being investigated/used for improving maternal outcomes. The UK has already launched the TOMMY APP (through the RCOG) for use to reduce PTB and stillbirths in the UK. In this episode we will highlight a new systematic review which assessed Machine Learning’s ability to predict stillbirth. Did this work? This is a h...

We all are aware that multiple adverse obstetrical outcomes have been linked to maternal obesity, such as stillbirth, preterm birth, NICUs admission, and congenital anomalies. But once delivery and hospital discharge occurs uneventfully, a new cohort study is raising the alarm for another possible adverse event up until the child’s first year of life: Sudden Unexpected Infant Death (SUID). SUID is...

Our immediate past episode summarized a validation study of cell-free DNA (cfDNA) isolated from maternal plasma for fetal RBC genotyping in alloimmunized patients. And now, in this episode, we will highlight a BRAND NEW ACOG Clinical Practice Update on this very subject! YEP... we now have new ACOG guidance regarding using maternal derived cfDNA for fetal RBC antigen detection as an option for car...

In September 2022, a cell-free DNA assay using next-generation sequencing and quantitative counting tech for fetal antigen status determination became clinically available in the USA. This allowed maternal screening for fetal RBC genotypes for RH negative patients. This test was recognized by thre ACOG in March 2024 as one option to “triage” anti-D immunoglobulin in RH negative women. But can this...

First off, let’s all agree that everyone has a different STYLE of sexual intimacy, and that’s OK. Yep, we all understand that there's always been a lot of sexual act “diversity” in the world… and throughout history. But there is a more recent trend that has increased in popularity, some surveys attribute it to its representation in pornography, that may be dangerous. This was in recent print a...

Candida in women is being right? Afterall, vulvovaginal candidiasis during pregnancy is common. Candida species may be isolated from the vagina of 15 %-21% of nonpregnant women; this rate increases to 30% during pregnancy. While it is generally benign and isolated to the vagina clinically, some Candida species have the capacity to be troublemakers. C. Glabrata has the potential to be a bad player,...

Biomarker testing has arrived in Obstetrics. Of course, we have been using some biomarkers for years, like PAMG1 (Amnisure) and AFP+ILGFBP1 (ROM Plus) for ROM evaluation. In May 2023, the FDA cleared Thermo Fisher Scientific's maternal serum biomarker test for prediction of preeclampsia with severe features in hospitalized patients (and we have a prior episode on that). Now, as of July 9, 2024...

Published studies, including 2 large network meta-analyses, support the safety and efficacy of misoprostol (PG E1) when used for cervical ripening and labor induction. Based on cumulative data, misoprostol administered vaginally at doses of 50 μg has the highest probability of achieving vaginal delivery within 24 hours. Prostaglandin E2 also has proven efficacy. Plus, we are all aware of the safet...

Tuberculosis (TB) was historically called "consumption" due to the dramatic weight loss and wasting away experienced by patients. The modern name "tuberculosis" was first published by J. L. Schönlein in 1832. Today, between 3% and 5% of the U.S. population are estimated to be living with latent TB infection. Contrast that with the worldwide statistics which state that nearly on...

Approximately 0.5% of all births occur before the 3rd trimester of pregnancy, and very early deliveries result in the majority of neonatal deaths and more than 40% of infant deaths. Preterm prelabor rupture of membranes (PPROM) is a known risk factor for preterm birth and is responsible for 30–40% of preterm deliveries. While PROM occurs around 8% of all (term) pregnancies, PPROM occurs around 1%...

Researchers estimate that more than 100 million women in over 120 countries use tampons during their menstrual cycle. Tampons are generally considered safe and healthy menstrual products. However, a new study conducted by researchers at the UC Berkeley School of Public Health has identified the presence of 16 different heavy metals in tampons from 14 different brands purchased in the U.S. and the...

It's Summer…and its getting HOT in here! Although the effect of heatwaves in pregnancy has been studied various times, the data remains limited because these studies are observational, with very heterogenous populations, so its hard to prove causation between heat exposure and adverse outcomes. Nonetheless, these associations are indeed concerning. YES…just to be clear, there are past studies...

Up to 1 in 10 reproductive-aged women are impacted by endometriosis. Dysmenorrhea is the most common pelvic complaint of adolescents. While most cases of primary dysmenorrhea in adolescents will be primary dysmenorrhea, Endo remains a possibility especially after 2-3 years of progressive symptoms. Although the true prevalence of endometriosis in adolescents is unknown, at least two thirds of adole...

Well, sometimes the "traditional", evidence-based recommendations don't have the desired result they are supposed to. When the "usual and standard" ways of doing things fail, its time for "shared-decision making"! In this episode, we will highlight, and give KUDDOS, to an OB care team who exampled thinking outside-the-box in order to care for an acutely ill patien...

RSV season is just around the corner (Fall and Winter months). Newborns are 16x more likely to be hospitalized with serious RSV lung infection than the flu. On August 21, 2023, the FDA approved the first RSV vaccine, Abrysvo, for use in pregnant individuals to protect newborns and infants against severe RSV disease in the first 6 months after birth. The FDA approved the vaccine to be administered...

A substantial collection of evidence indicates that the fallopian tube serves as the primary site of origin for a large portion of high-grade serous ovarian cancers. As a result, clinical practice guidelines (including from the ACOG) recommend salpingectomy for permanent contraception- when necessary- rather than simple tubal ligation. But an August 2023 publication, in JAMA Network Open, stated t...

Approximately 20% to 25% of pregnancies end in miscarriage, and there are many medical reasons why it may occur. About half are caused by chromosome aneuploidy. However, less than 5% of women will experience a second first trimester loss, and less than 1% will experience three early losses. The incidence of early spontaneous pregnancy loss increases by maternal age. In this episode, we will highli...

Happy Independence Day, America! We hope you are enjoying this wonderful, national holiday. Yep...Its a PARTY in the USA! In light of the festivities, here's a clinical question for us: Do fireworks affect the fetus? Even broader than that, do loud sounds in general affect the developing child? The answer is both YES and NO. Listen in to this short- yet fun- episode as we prepare to light the nigh...

(Here’s a WONDERFUL QI Project for this New Residency Academic Year) With 70.8% of pregnancies among adolescents being unintended, there is a clear need for increased access to contraceptive services. Many adolescents use the emergency department (ED) as their primary healthcare source, highlighting the importance of providing comprehensive sexual health services in this setting. The risk of pregn...

PROM occurs in approximately 10% of pregnancies and leads to a risk of IAI in women that is 3 times higher than that in non-PROM women. The risk of early-onset sepsis of neonates born to mothers exposed to PROM is 20 times higher than in non-PROM mothers. An increasing time period with PROM increases the risk of infection for both mothers and newborns accordingly. Nonetheless, the ACOG states that...

Podcast Family, I hope this episode gives you pause and brightens your day 🌞. Just a quick work and acknowledgement to likley our YOUNGEST podcast family member and his mother, a Co-OBGYN preparing for oral Boards. 👏👏 Let this speak to you as the message spoke to me! (and introducing ​callmestevieray & Connor Price, whose words/song- “GRATEFUL”- always lightens my load). 🎶👏🎶👏🎶

Oral Hormonal contraception gets the blame for a lot of things, including the development of hypothyroidism. Hypothyroidism is one of the most common endocrine disorders affecting 5 to 10 times more women than men, and its prevalence increases with age. This association of OCPs with hypothyroidism comes from a controversial article in BMJ published in 2021, but is still very active in current soci...

Podcast Fam, on March 27, 2024 our episode was called "Balloon for PROM: Yea or Nay". Although mechanical cervical balloons for induction were the focus, we also discussed which medication is better (based on published data) for labor induction after PROM. Well, in this episode, we pick up from March with ANOTHER NEW STUDY released today (June 25, 2024) in AJOG MFM. This RCT builds on the evidence...

Anxiety disorders are the most common mental health issue in the United States, affecting nearly 1 in 5 adults, or 40 million people. Another 19 million adults – 8% of the population – has depression. Prenatal mood disturbances are known to affect the fetal brain, and endocrine system. Left amygdalar volumes were smaller in newborns whose mothers had high psychological distress during the COVID-19...

Respect for patient autonomy is a fundamental part of the clinician-patient relationship and discussion of healthcare interventions. Some patients decline transfusion of blood products, either for religious or non-religious reasons, but most frequently as part of the Jehovah’s Witness faith. Acceptance of, and decision-making, surrounding blood products and human blood derived medications is compl...
