Refresher of Genetic MD
Nov 2100:24:45Summary readyMuscular 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.

Summary
Use GA at CS Electively? Maybe, Maybe.
Nov 1900:35:42Summary readyRegional 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.

SummaryLido Patches After CS? Maybe.
Nov 1800:19:38Summary readyThe 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.

SummaryMore Measles Material
Nov 1700:30:46Summary readyPodcast Family, we have covered the subject of Measles previously on this show (links below). Those episodes were a preview of what has now been released ahead of print as a narrative review in the Green Journal! In this episode, we will summarize the KEY points of measles infection in pregnancy and re-state the “rule of 4” and the importance of the number 10 regarding this.1.

SummarySelf-Hypnosis For Hot Flash Relief.
Nov 1200:17:44Summary readyThe term "hypnosis" was first described in 1843 byScottish surgeon James Braid, who published the book Neurypnology. He coined the term "hypnosis" from the Greek word for sleep to describe the trance-like state induced by focusing on a bright object. Self-hypnosis has nowbeen shown to aid in menopausal hot flash reduction! In this episode, we will review this brand new publication from JAMA Network which confirmed via a multicenter RCT that a simple daily hypnosis audio session was effective forsymptom relief. The study is the first to compare self-guided hypnosis with an active control condition (i.e. sham white noise control group). Listen in for details. 1.

SummaryHISTORY MADE: New HRT News TODAY (11/10/25)
Nov 1000:14:48Summary readyOn August 15, 2025, we reviewed the data from an FDA expert panel calling on the FDA to remove the exiting Black Box warning on commercial HRT options for menopausal care. In a historic decision, this happened today.

SummaryA BMI-Based Labor Curve?
Nov 900:24:13Summary readyThe ACOG acknowledges that maternal obesity affects labor curves and recommends allowing more time for cervical dilation before diagnosing labor arrest in obese patients. This approach aims to avoid unnecessary interventions, such as premature cesarean delivery, which may occur if standard labor curves are strictly applied to obese women. In this episode, we will review a new study from the AJOG (08 Nov 2025) which describes labor progression and duration according to maternal body mass index, validating the need (possibly) for a BMI -based labor curve. Has there been advocates of a BMI-based labor curve? Listen in for details.1. Edwards, Sara et al. Characterizing Labor Progression and Duration According to Maternal Body Mass Index.

SummaryUse Antibiotics at 2nd Degree OB Lac Repair?
Nov 600:28:22Summary readyDo you routinely order prophylactic antibiotics at time ofsecond-degree laceration repair? Is there data for that? While the use of prophylacticantibiotics “is reasonable” (per ACOG PB 198) for OASIS lacerations, what doesthe data look like for second degree lacs? Well, the answer is both supportiveAND non-supportive of that practice! In this episode, we will cover a brand newpublication (RCT) from BMJ on this very issue, and also highlight a meta-analysisfrom Plos One (May 2025) that also examined this question.

Summary“New” PCOS Info: 4 Types (AGAIN)
Nov 500:30:38Summary readyOn March 29, 2023, we released an episode titled, “The 4 PCOS Phenotypes”. That was in 2023! Now, on 29 October 2025, in the journal Nature Medicine, researchers have published, “Data-driven (FOUR) subtypes of polycystic ovary syndrome and their association with clinical outcomes”. PCOS is not ONE condition: is a constellation of metabolic, endocrine, and ovulatory dysregulation. We covered these 4 phenotypes back then. Is this what the “new data” found? Or what it something else? And how does these affect IVF or pregnancy outcomes? Listen in for details!1. Gao, X., Zhao, S., Du, Y. et al.
