Hyst + BSO for BRCA Risk Reduction?
Feb 2400:26:28Summary readyApproximately 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and the ovaries are now removed, the sole purpose of the uterus- which is to initiate, nourish, and grow a child -is no longer applicable. Is there a call for inclusion of a hysterectomy at time of risk reducing BSO? This has vast and important implications regarding subsequent hormone therapy. In this episode, which comes from one of our podcast family members, we will dive into the latest data pushing towards the inclusion of hysterectomy at time of prophylactic BSO. It's fascinating data from just last year (2025, in the Journal of the NCI). Listen in for details.1. Kotsopoulos J, Seca M, Gronwald J, et al.

SummaryNew Data: Screen Maternal Ferritin with Prenatal Care?
Feb 2100:22:11Summary readyThe 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. However, up to 42% of women who enter prenatal care are iron deficient BEFORE anemia is detected. Iron deficiency itself, even without anemia, has also been linked to pregnancy morbidity. The ACOG currently does not have a statement endorsing universal ferritin screening in pregnancy outside of established anemia, but new data is challenging this (Jan 2026, Lancet).

SummaryAlex’s Input: Aspirin’s Awkward Acumen
Feb 1800:19:11Summary readyWe 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 Alex. Alex sent me an incredible and insightful message which was a rebuttal to my Southwestern colleagues’ findings. In this episode you'll hear Alex's rebuttal and clinical conundrum, and we will explain why these two seemingly paradoxical findings makes sense. Listen in for details.1.

SummaryMore Support for 162mg LDA Universal Use in OB
Feb 1600:22:56Summary readyWell, 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 of UT Southwestern which was just published at the SMFM Annual Pregnancy meeting in Las Vegas.

SummaryGDM vs “Early” GDM vs PrePreg DM: A Proposal
Feb 1300:28:19Summary readyAs 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”. In this guidance, it states, “At this time, there are insufficient data to support the best screening modality for pregestational diabetes in pregnancy, but consideration can be made to use the same diagnostic criteria as for the nonpregnant population (A1c value 6.5 or higher, or fasting plasma glucose value 126 mg/dL or higher, or 2-hour plasma glucose value 200 mg/dL or higher during a 75-g OGTT, or random plasma glucose value 200 mg/dL or higher in patients with classic hyperglycemia symptoms)”. However, a new proposed protocol has been published in AJOG for early screening for DM in pregnancy. This also describes the differences in diagnosis and care for Standard GDM diagnosed at 24-28 weeks, vs a diagnosis of pregestational DM diagnosis made prior to 20-weeks vs “early” GDM also diagnosed under 20 weeks of gestation.

SummaryHPV? Check Your Pad.
Feb 1000:18:44Summary readyThere 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 awkward: the use of menstrual blood as an HPV screening test. In this episode we will review a new cross-sectional, population-based study from China which compared testing menstrual blood for human papillomavirus during cervical cancer screening to clinician-collected cervical samples for human papillomavirus (HPV). This concept, and these results, are not new at all! And there are important limitations to consider at this time. Listen in for details.1.

SummaryYou Ask, We Answer!
Feb 800:27:49Summary readyWell 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 because it's not as intuitive as you would think. We will explain in this episode and there is a bit of a contradiction in the guidance. The second question has to do with finding an asymptomatic uterine rupture at cesarean section. Is there such a thing as a “partial” (silent) uterine rupture? There's recent data from 2025 about this. Listen in for details.1. ACOG PB 181; 2017. 2. Baek S, Froese V, Morgenstern B.

SummaryUnderstanding Fetal Microcephaly
Feb 500:29:58Summary readyFetal 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 feeding, vision and hearing problems. Prognosis depends on the severityof the microcephaly and whether it is associated with other anomalies. What SD is diagnostic of microcephaly? What are the potential etiologies? What genetic syndromes are most associated with true microcephaly? Is fetal cranial MRIrecommended? Listen in for details. 1.

SummaryOB Cough Induced Rib Fracture? YEP. It’s a Thing.
Feb 200:18:44Summary readyStress fractures are common injuries in athletes and military recruits, that’s’ understandable- based on the physical forces placed on the long bones. A stress fracture can be defined as a partial or complete fracture of the bone that is a result from repeated application of stress lower than that required to fracture the bone in a single loading situation. In pregnancy, the body is subjected to various physiological changes that make women more vulnerable. In this pregnancy, we will highlight a REAL patient case which our team cared for on the inpatient service where a simple cough at 34 weeks leads to a painful spontaneous rib fracture! Is there any data published on this? Are serum tests for bone turn-over required as part of this workup?

SummaryWhen ZMAX if OUT for CS: Alternative?
Jan 3100:17:05Summary readyWe have learned a lot about extended spectrum coverage of prophylactic antibiotics for cesarean section. The landmark C/SOAP trial randomized 2,013 women undergoing nonelective cesarean delivery to azithromycin 500 mg IV plus standard prophylaxis versus placebo, demonstrating a 51% reduction in the composite outcome of endometritis, wound infection, or other infection. Adjuvant Zmax (plus standard first-generation cephalosporin) is now recognized as evidence-based antibiotic coverage for intrapartum cesarean, cesarean with ruptured membranes, and patients with obesity. This last patient characteristic comes from the ERAS latest update. But what is ZMAX is not available? Is there an evidence-based peri-op alternative in these cases? Does Gent and Clinda cover mycoplasma/Ureaplasma? What about postop flagyl? Listen in for details. 1. Tita AT, Szychowski JM, Boggess K, et al.
