    BOGO! (With Hanna, PGY1)

    As I have said many times before, some podcast ideas come from REAL clinic encounters. In this episode, Dr Hanna V, our dedicated PGY1 on our call team, and I will answer TWO real questions which arose just today on morning rounds, on our service: 1. Does NORMOTENSIVE HELLP still need Mag Sulfate? And 2. Does an indwelling foley s/p iatrogenic bladder injury at CS require prophylactic antibiotic coverage for urinary infection? Yep: It’s a BOGO sale on today’s podcast- Buy ONE GET ONE! Listen in for details. 1. Gestational Hypertension and Preeclampsia: ACOG Practice Bulletin, Number 222. Obstetrics and Gynecology. 2020.

  2. Hantavirus & Pregnancy FAQ

    Hantavirus & Pregnancy FAQ

    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 in pregnancy. 1. Gilson GJ, Maciulla JA, Nevils BG, et al.

    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 related study, “The association between unintended hysterotomy extensions with cesarean delivery and subsequent preterm birth”. In this episode, we will review a new narrative review (in the Green Journal, May 3, 2026) of unintended hysterotomy extension at C-section. We will summarize known risk factors and focus on subsequent uterine rupture risk. Does unintended hysterotomy extension at CS increase TOLAC uterine rupture? It’s complicated. Listen in for details. 1. Giugale LE, Sakamoto S, Yabes J, Dunn SL, Krans EE. Unintended hysterotomy extension during caesarean delivery: risk factors and maternal morbidity.

    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. Although rare, this may lead (over a third of cases) to some adverse perinatal issues. Listen in for details. 1. ACOG PA Jan 2026: Screening for Fetal Chromosomal Abnormalities 2.

  5. GLP1 Periconception Exposure and OB Outcomes

    MAY 4

    GLP1 Periconception Exposure and OB Outcomes

    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) demonstrated that both GLP-1 and the GLP-1 receptor are present in mouse embryos as early as embryonic day 6 (E6) and continue through the first trimester, as well as in pluripotent mouse embryonic stem cells. In these undifferentiated cells, GLP-1 modified the expression of endodermal, ectodermal, and mesodermal gene markers, as well as critical developmental signaling molecules. So, there is a concern about embryogenesis if inadvertent exposure to these meds occurs in early pregnancy. In this episode, we will summarize 2 recent and separate systematic reviews (March 2026; April 2026) on fetal/OB outcomes after periconceptional exposure. This builds on the Parker data set from 2025. One of these reviews, from April 2026, is also a meta-analysis. Listen in for details. 1.

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

    MAY 1

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

    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 several years- in the last data review was in January 2026 in Lancet. Even the correction of hyponatremia has evolved. Should we be following urine ketones for patients being treated for HG? Is Dextrose needed? Listen in for details. 1.

    Novel LUS Compression Sutures for Previa Bleeding

    Uterine compression sutures are effective, uterus-sparing techniques for managing severe postpartum hemorrhage (PPH) due to atony, avoiding hysterectomy. Key types include the B-Lynch suture (vertical, brace-like), Hayman suture (simplified vertical), and Pereira sutures (multiple, comprehensive sutures), and Cho Compression (quadrant square anterior to posterior closures), are applied when pharmacological methods fail. But these, while helpful with atony, do not address the LUS bleeding from previa which are below these applications. Even the O’Leary lateral sutures are often higher tha the bleeding and thin, anterior LUS affected by previa. Previa is a significant risk factor for PPH. In this episode, we will highlight 3 novel suture techniques which have been in print (TWO as recent as January 2026) which can be effective in stopping the LUS bleeding and avoiding hysterectomy. We will highlight the transverse circumferential purse string, the simple transverse Nausicaa suture, and the LUS WaveForm suture. These are easy to use and may be lifesaving. 1.
