• LDA for Unexplained Recurrent SABs?

  Recurrent pregnancy loss (RPL) affects approximately 5% of couples and is an emotional burden on those affected. There is some evidence that vaginal progesterone supplementation may be considered in patients with recurrent pregnancy loss who are experiencing vaginal bleeding during the first trimester. But what about prophylactic low dose aspirin in the first trimester, or preconceptionally, for unexplained RPL? Is that evidence-based? A new publication from the SMFM’s journal Pregnancy has examined this. Listen in for details. 1. 22 November 2025: Low-dose aspirin in unexplained recurrent pregnancy loss: A systematic review and meta-analysis (Pregnancy): https://obgyn.onlinelibrary.wiley.com/doi/10.1002/pmf2.700992.

• Change Gloves After Placenta at CS? Yes, and No.

  Having data is sometimes different than having clinically applicable data. This is exactly the issue with the proposed plan to reduce surgical site infection (SSI) by changing surgical gloves after placental delivery at C-Section. Just 24 hours ago, we received the question from a PGY4 OBGYN resident asking whether the practice of changing surgical gloves at C-Section after placental delivery to reduce SSI was evidence-based. So, in this episode, we will review the data - which is timely since this was recently published on November 13, 2025 in the J Hospital Infection. This study follows a statement on this practice released by FIGO in September 2025. It’s an interesting proposal, and there is clearly data in support of this, yet the ACOG and CDC do not recommend this practice as of Nov 2025. Is there a disconnect? Listen in for details. 1.

• Refresher of Genetic MD

  Muscular dystrophy (MD) is a group of genetic diseases that affect about 16 to 25 per 100,000 people in the US, with the most common childhood form being Duchenne muscular dystrophy (DMD) and the most common adult form being myotonic dystrophy. The prevalence of DMD is estimated at around 1 in 3,500 live male births. Prenatal carrier screening for this is part of the ACMG Tier 3 expanded carrier panel. This is different from spinal muscular atrophy (SMA). As we recently had a patient who was a MD carrier, with affected male children, who we cared for, we decided to do a quick review of muscular dystrophy: its prevalence, genetics, and evaluation of asymptomatic maternal carriers.1. https://www.mda.org/disease/duchenne-muscular-dystrophy/causes-inheritance2.https://www.nichd.nih.gov/health/topics/musculardys/conditioninfo/causes3. https://www.nhs.uk/conditions/muscular-dystrophy/4.

• Use GA at CS Electively? Maybe, Maybe.

  Regional anesthesia, typically with a spinal or epidural, haslong been favored for cesarean births due in part to concerns about the effects that general anesthesia (GA) may have on newborns at delivery. However, data has shown that up to 1 in 6 women may experience pain with a “topped-off”labor epidural, during the cesarean. A new publication in the journal Anesthesia is now being interpreted as implying that general anesthesia may be a valid alternative electively. Is that what this new study found? Has GA been linked to postpartum depression? What about later child neurodevelopmental delays? This is a fascinating topic…Listen in for details. 1.     Langer, Sarah M.D.1; Lim, Grace M.D., M.Sc.2;Qiu, Yue M.D.3; Biaesch, Jingyuan D.O.4; Neuman, Mark D. M.D., M.Sc.5.

• Lido Patches After CS? Maybe.

  The US has no shortage of lidocaine patch television commercials. Topical lidocaine has a role for local, topical, minor aches and pains. What about lidocaine patches for post-op cesarean section pain? Is there data for that? A brand-new meta-analysis in AJOG-MFM (Nov 13, 2025) looks at this option. However, there has been 3 prior reviews on the same topic from 2019, 2022, and 2023. Do they all arrive at the same result? Listen in for details!1.     Smoker J, Cohen A, Rasouli MR, Schwenk ES.
