Dr. Chapa’s OBGYN Clinical Pearls

Medicine has traditionally been practiced “in silos”. But compartmentalization of medical practice/interventions can leave gaps in patient care. Patients win when they have increased access to a variety of medical therapies or contraceptive options. In this episode, we will review a brand new publication (released ahead of print) from the AJOG. We've decided to call this episode, “Internists,...

TWICE BEFORE, we have covered Pitocin use intrapartum: 1. On Oct 24, 2022 we covered, “Save the Pitcoin! Safe to Stop Pit Once in Active Phase?”, and 2. On Sept 24, 2024 we covered, “Labor Hacks: Pit Breaks”. Nonetheless, today's episode yet again focuses on pitocin in labor. On March 18, 2025, a new systematic review and meta-analysis was released ahead of print in the AJOG. This looks at ces...

Fresh off the heels of our immediate last episode, we bring you a perspective from the trenches! Sarah, a Clinical Pearls podcast family member, is a health professional who works with autistic individuals. Sarah has provided clear and evidence-based data which helps to explain the rise of autism in the US over the last decades. Our podcast community is Incredible! Her noted and data driven perspe...

Autism Spectrum Disorder (ASD) has an alarming trend of rise in the US. Currently, 1 in 36 (or 1 in 40 in some reports) have an ASD diagnosis. For this reason, ASD remains in the spotlight as researchers remain dedicated in explaining its origin. Over the last few years, there have been publications suggesting a link between one of the most common symptoms of pregnancy (nausea and/or nausea togeth...

Fasting during the lunar month of Ramadan (Feb 28 to March 30, 2025) is a core practice for Muslims across the world. During Ramadan, Muslims abstain from food and drink from dawn to sunset. However, during a singleton pregnancy, the ACOG recommends adding approximately 340 extra calories per day in the second trimester and 450 extra calories per day in the third trimester. Does fasting during Ram...

Infants born by vaginal birth are exposed to maternal vaginal bacteria, which are one of the contributing influences on the subsequent development of the infant’s microbiome. This process is altered by cesarean delivery, which changes the initial microbiome of the neonate. It is theorized that infants born by cesarean delivery have an increased risk of chronic inflammatory conditions due to altere...

On Feb 24, 2025, the FDA granted approval for MIUDELLA®, a hormone-free, low-dose copper IUD developed by US manufacturer Sebela Women's Health Inc (Georgia) for contraceptive use in females of reproductive potential for up to 3 years. MIUDELLA® utilizes a small, flexible nitinol frame and contains less than half the copper of currently available copper IUD. Where have we seen nitinol before??...

BV is a vaginal dysbiosis resulting from replacement of normal hydrogen peroxide and lactic-acid producing  Lactobacillus  species in the vagina with high concentrations of anaerobic bacteria. Recurrent BV can occur in 50-70% of women after an initial diagnosis. The concept of treating the male partner for BV recurrence prevention is not new, and the results have been conflicting. However, a new p...

Thank you to our GREAT podcast family members who fixed by history regarding "Hollyweird" ! And thank you DANNY Thomas for your legacy at SJCRH. Go Memphis!

Screening for spinal muscular atrophy (SMA) should be offered to all women who are considering pregnancy or are currently pregnant. SMA is an autosomal recessive disease characterized by degeneration of spinal cord motor neurons that leads to atrophy of skeletal muscle and overall weakness. Once identified, oral therapy may be started in the neonatal interval for those with the most severe phenoty...

Vitamin D gets a lot of attention, and it should, mainly for its known role in bone stability. However, vitamin D has significant additional roles in physiology. Vit D, and its metabolites, also functions as modulator of inflammatory and immune responses. According to a number of recent studies, this important micronutrient plays a complex role in numerous biochemical pathways in the immune system...

According to published estimates, the prevalence of an NSAID allergy (hypersensitivity) in the general population is estimated to be between 0.5% and 2%, with some studies reporting a range of 1-3% of people experiencing a reaction to NSAIDs; however, this rate can be significantly higher in individuals with conditions like asthma, nasal polyps, or chronic urticaria, where it may reach up to 20-30...

Its BACK. While the current outbreak is in western Texas and Eastern NM, it is expected to spread to other States. Measles is an acute viral respiratory illness characterized by fever, malaise, cough, conjunctivitis, a pathognomonic enanthema (oral lesions), followed by a maculopapular rash. In pregnancy, this could lead to significant maternal and fetal morbidity. What are Koplick Spots? What is...

The ACOG's PB 205 (2019; reaffirmed Aug 2024) states that "when compared with spontaneous labor, induced labor is associated with a lower likelihood of achieving VBAC". Additionally, that guidance states, "Several studies have noted an increased risk of uterine rupture in the setting of induction of labor in women attempting TOLAC". These are important observations to review with a patient. Howeve...

Funic presentation, the umbilical cord presenting as the leading feal component seen on ultrasound, may be a transient phenomenon and is usually considered insignificant until ~32 weeks. However, its persistence beyond that gestational age raises the possibility of cord prolapse intrapartum as cervical dilation progresses. Cord prolapse is a mostly unpredictable obstetric emergency, in which the u...

One in five women in the U.S. have a BMI of 30 or more at the START of pregnancy. Around 1 in 5 women gain more than 40 pounds during pregnancy, which is more than any woman should gain. Only about one-third of women gain the recommended amount of weight during pregnancy. Gaining too much weight during pregnancy can increase the risk of HDP, GDM, fetal macrosomia, and can cause complications of bi...

Estimates of Postpartum Urinary Retention (PUR) incidence vary widely from 1.5% to 17.9%, with undiagnosed cases making the true incidence difficult to determine. A postvoid residual (PVR) volume of <150 mL is typically considered appropriate for normal bladder emptying, but this has been in the nonpregnant/non-postpartum population. In this group, some have proposed a PUR of up to 500ml as nor...

In 2013, The ACOG’s Hypertension Task Force suggested that NSAIDS not be used in postpartum patients with hypertensive disorders of pregnancy due to theoretical concerns on BP aggravation. But “medicine moves fast”. In 2020, the ACOG “green lighted” ibuprofen use postpartum in these patients if no evidence of renal insufficiency was present. In episode, we will review a brand-new publication (soon...

(We were made aware that this original posting had the last section DROPPED accidentally)...here is the full episode! Ahhh...TECHNOLOGY! *This is why AI will likely replace our production team...Just kidding production team, just kidding). Episode Details: Well, we typically focus on ONE or maybe TWO publications to highlight and review. However, in this episode, which we have decided to call, “Su...

Well, we typically focus on ONE or maybe TWO publications to highlight and review. However, in this episode, which we have decided to call, “Survey said…!”, we will go through some common and REAL WORLD “mental battles” regarding what is and what is not part of a diagnostic criteria. These are every day OBGYN things that we KNOW, but when asked to define them…we can easily get ourselves confused....

Yep, its an area of debate and confusion. Controversy surrounds the diagnosis of CHTN with severe BPs vs superimposed preeclampsia with severe features. Do you need “new onset proteinuria” for the diagnosis of superimposed preeclampsia over CHTN? What about “with severe features”? This is something that is very clear to understand, yet muddy; there is well defined guidance here which is grey! Yep,...

According to the ACOG, eclampsia is a low frequency, high acuity emergent condition. The rate of an eclamptic seizure is 1/200 in those with preeclampsia without severe features but is 4 fold higher ( 4/200 ) in those with preeclampsia with severe features. Traditionally, “textbook eclampsia” management did not include cranial imaging. However, that consensus is changing! In this episode, we will...

Well, in this episode we have a “3-in-1” subject review. Often in medicine, we find ourselves with some data to guide us, but definitely not a “predominance of evidence”. So in caring for our patients, we often come to the conclusion that doing a course of action can possibly help, and can't hurt... and therefore our plan “sounds reasonable”. That's the focus of our episode today! We'r...

Venous thromboembolism (VTE), which includes deep vein thrombosis and pulmonary embolism, is responsible for 9–30% of pregnancy-related mortality in high resource countries and remains a significant, increasing cause of severe maternal morbidity. Peripartum, 50% of VTE events occur in the postpartum interval, which has a 6-fold higher risk compared to antepartum. There is wide variation in LMWH ph...

This- is-CNN. No, that THAT CNN...This is Chapa News Network! WE have late-breaking news developments on 2 fronts: 1. The ACOG has released a clinical update (ACOG ROUNDS) in response to a recent study associating the RSV vaccine and GBS (we covered this study in a past episode). 2. The FDA has EXPANDED the label for an intranasal therapy for Treatment Resistant depression (TRD). Listen in for det...
