  • Alex’s Input: Aspirin’s Awkward Acumen
    Feb 18 2026

    We 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.

  • More Support for 162mg LDA Universal Use in OB
    Feb 16 2026

    Well, 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. Listen in for details.

  • GDM vs “Early” GDM vs PrePreg DM: A Proposal
    Feb 13 2026

    As 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. Listen in for details.
