Dr. Chapa’s OBGYN Clinical Pearls

Antenatal corticosteroids are a MAJOR win in the management of preterm labor. An initial course of antenatal corticosteroids has been shown to reduce morbidity and mortality in patients with preterm prelabor rupture of membranes. For patients who remain undelivered after the initial course of antenatal corticosteroids, it is uncertain whether a booster course of antenatal corticosteroids reduces neonatal morbidity or increases the infection risk. The ACOG, in its current guidance, has concluded that the current evidence is insufficient to make a recommendation. Corticosteroids, especially at the doses given, are also powerful immunosuppressants. When you administer that first course, you accept a minor, calculated risk for a massive, proven benefit. But when you introduce a second course of steroids into a uterine environment that has already been ruptured and exposed to vaginal flora for weeks, you are pouring fuel on the fire. PLUS, the environment for the fetus with prolonged preterm prelabor rupture of membranes is unique. PPPROM, the chronic exposure to ruptured membranes and the resultant oligohydramnios is theorized to trigger a kind of stress response in the fetus- so the baby may make their own endogenous corticosteroid flare. So, rescue steroids after an initial course of steroids in PPROM cases has remained controversial but we have updated data that has provided new insights. In this episode, we will highlight an RCT from 2023 and a more recent systematic review and meta-analysis from May 2026 on this very subject. Listen in for details.

The Bakri Postpartum Balloon was described and first used clinically in 1999 by Dr. Younes N. Bakri (Georgia, USA). It is intended to treat postpartum hemorrhage (PPH). In the United States, it received its first major FDA clearance (via 510(k) for commercial marketing) on April 17, 2002. Manufacturer guidelines for the Bakri (Cook Medical) state that the balloon may be left indwelling for a maximum of 24 hours, but the determination of removal time is left to the clinician once “bleeding is controlled and the patient is stable.” However, the optimal duration of intrauterine balloon tamponade placement remains unclear. One retrospective cohort study from AJOG (Einerson et al) of 274 women found no significant difference in PPH outcomes when intrauterine balloon tamponade was left in place for 2–12 hours, compared with more than 12 hours. However, only 30 women had the intrauterine balloon tamponade placement for 10 hours or less. And remember, this was not a prospective trial looking at a minimum of 2 hours, 2 hours was just the lower margin of the “short duration” group. Now, a new RCT (with authors from Denver and Vermont) published in the July 2026 Green Journal provides new data. In this first of its kind pragmatic, randomized trial of noninferiority, a 6-hour duration of intrauterine balloon tamponade usage for postpartum hemorrhage (PPH) control was compared with an 18-hour duration.

Gonadal hormones have a complicated influence on appetite. Estradiol generally suppresses appetite, whereas progesterone opposes estradiol's action such that their combined presence represents a high-risk hormonal milieu for Binge Eating (BE). Testosterone is thought to be associated with increased BE in females but appears protective in males. In some reports, combination oral contraceptive (COC) use has been linked to greater BE-related appetitive processes (e.g., food intake). Now, we have 2 recent, back-to-back publications (June 2026 in JAMA Network Open, and July 2026 in Appetite) that have examined the relationship of hormonal contraception on binge eating behavior. These found seemingly opposing conclusions. Listen in for details.

The DIY at-home gynecology health market has EXPLODED. There is at-home vaginal/cervical HPV testing, screening for STIs, and even a blood test for multi-cancer screening (Cancer Guard). These provide a potential solution for access to care and social determinants of health. Now, a new study is seeking to add DIY at-home transvaginal ultrasounds to that mix. Yep…at home. This was published in Jama Network on July 6, 2026. Premenopausal women aged 22 to 50 years participated from 12 different locations in the US, including my home state of Texas. In this episode, we will highlight this new prospective, interventional, single group nonrandomized clinical trial. Listen in for details.

As healthcare professionals, we should all seek and encourage scientific and medical discovery and new therapies. That’s one big goal of the scientific process: to bring new therapies to otherwise lethal condition. For example, back in the 80s and 90s, HIV uniformly led to AIDS, which was a death sentence. But now, HIV is 100% manageable with appropriate medical care and medical therapy. That’s a win! On the Prenatal side, lack of amniotic fluid (anhydramnios) under 22 weeks has uniformly been regarded as a fatal/lethal condition. This is because of the direct association with previable lack of amniotic fluid and lung hypoplasia. But now, serial amniocentesis for this condition is making headlines. While the headlines are catchy and serve as appropriate “click bait”, there’s more to this story. This may be a perfect example of “Robbing Peter, to Pay Paul”. Listen in for details.
