Dr. Chapa’s OBGYN Clinical Pearls

The vast majority of the time, “community standard of care” reflects evidence-based recommendations. This means that both the predominance of clinical data and what is clinically practice align one with another period but at times, clinical standard practice doesn't always align with what the data shows. How is this possible? This is exactly the case for home blood pressure monitoring in pregnancy (HBPM). This episode idea comes from an OB PGY-3, soon PGY-4, who asked his attending this brilliant question: “If the BUMP1 and BUMP2 clinical trials did not show a benefit with HBPM, why are we still doing it?” That is a complicated question that has a solid answer! Unsatisfied with his response, he asked for our opinion. Listen in for details.

Outside of pregnancy, guidelines emphasize diabetes self-management education and support to facilitate informed decision making, self-care behaviors, problem solving, and active collaboration with health care professionals. This includes, in those with good health literacy, the concept of patient-led self-titration of basal insulin results which has data that it improves glycemic management compared with clinician-led titration for type 2 diabetes among nonpregnant adults. But what about for GDM? Can patient’s self manage their BASAL insulin? In this episode, we will review a new RCT published in April 2026 in the Green Journal on this very subject. As novel as this is, it is not the first to report on this as it was also published (retrospective study in the UK) in 2022. This is a novel approach to insulin in GDM but there are some questions that remain. Listen in for details.

Hyperemesis gravidarum (HG) represents the most severe end of the nausea and vomiting of pregnancy spectrum. It has a reported incidence of approximately 0.3–3% of pregnancies and is the most common cause of hospitalization in early pregnancy and the second most common cause of hospitalization in pregnancy overall. In June 2024, the ACOG published a Clinical Expert series summarizing the inpatient management of HG. In that guidance, it describes mirtazapine as an “alternative pharmacologic” option. How effective is this medication compared to ondansetron? A new study (published ahead of print on 12/30/25 and officially out June 2026), out of Denmark, sheds some new light on this medication. This trial is the first double-blind RCT comparing mirtazapine to ondansetron AND placebo. Although a BIG limitation of this study exists (which we will discuss), it does provide some interesting insights. Listen in for details.

Cervical exams can be tricky for the novice practitioner. Think about this: it’s a blind exam, we measure that distance using only two fingers, through a layer of tissue, sometimes with a patient moving up on the bed as we examine. That is the reality of a cervical exam. Intrapartum, some nursing staff and clinicians use qualitative descriptors like "a tight 4" or "a generous 5" to convey nuance. In line with this, some report cervical examinations in “half- centimeters”. This sounds like this: “well, her last cervical exam was 5cm but now she is 5 and a half”. Is that a thing? What does the data say? Listen in for details.

Oh, What’s in a Name? Irving F. Stein and Michael L. Leventhal first described the syndrome, originally known as Stein-Leventhal syndrome, in 1935, in the AJOG. They published a case series of seven women displaying a triad of symptoms, including hirsutism, amenorrhea (absent menstruation), and bilaterally enlarged polycystic ovaries. We now know that PCOS affects 1 in 8 women globally (170 million women of reproductive age worldwide), and that there are 4 main manifestations of the condition- reflecting its diverse phenotype. Now, as of 05/12/25, a collaboration across 56 leading academic, clinical, and patient organizations, as well as iterative global surveys that garnered responses from over 14,300 people with PCOS and multidisciplinary health professionals have endorsed a NEW term (Lancet) for this: polyendocrine metabolic ovarian syndrome. This is actually STAGE 7 of an 8 stage process Yep, 1-6 are already done). But hold on…this is not taking over tomorrow! There is a THREE-YEAR implementation strategy that has already gotten started and culminating in 2028. Listen in for details.
