Dr. Chapa’s Clinical Pearls.

From 2012 to 2021, congenital syphilis cases in the United States increased by 755%. According to the CDC, 88% of congenital syphilis cases in 2022 could have been prevented with timely screening and treatment. Despite repetitive messaging about the need to identify syphilis early in pregnancy, with appropriate treatment, gaps remain. A new publication in the Green Journal (4/17/24) provides shocking information about gaps in diagnosis and treatment. In this episode, we will review that original research as well as summarize the new ACOG Practice Advisory (April 2024) regarding screening for syphilis in pregnancy.

There is a STRONG debate within the medical community as to whether testosterone should be prescribed to women during menopause and the time before and after it. Social media influencers and other media personalities are touting testosterone as a cure-all for mood, sex drive, cognitive changes, fatigue, reduced muscle strength, and other symptoms associated with menopause. In fact, the number of testosterone prescriptions for women has risen within the last five years in the United States and internationally. But is that evidence-based. The answer is both YES and NO. In this episode, we will focus on testosterone replacement for female low sexual interest. We will highlight the position statements from a large international coalition in 2019, a separate 2021 position statement, and the opinion of the ACOG. We have LOTS to cover here, so go lather up with your testosterone cream (JK) and listen in!

While the importance of optimizing a woman's hemoglobin level during the peripartum period has been emphasized in recent guidelines by the Society for Obstetric Anesthesia and Perinatology, the ACOG, and the Enhanced Recovery After Surgery Society, postpartum anemia remains a real issue in both the developed and developing world. Postpartum anemia has been associated with depression, fatigue, impaired lactation, and impaired cognition. This may lead to impaired maternal-child bonding. Additionally, severe anemia during the antepartum interval is an important predictive factor of PPH! This relationship was shown in a published meta-analysis in 2021. Postpartum, IV Fe has been proven to be of value for asymptomatic anemia. Packed RBC transfusion may be recommended for women with postpartum hemoglobin levels

Amnioinfusion was first described in 1976 using a rhesus monkey model. In that landmark study, the authors reported that variable decelerations occurred when amniotic fluid was removed from the uterine cavity and resolved when it was replaced. Although this experiment established that variable decelerations related to oligohydramnios and cord compression could be corrected by amnioinfusion, the technique did not achieve clinical application until 1983, when a novel approach to the relief of variable or prolonged decelerations was described. Amnioinfusion is mainly utilized in the rescue of recurrent fetal variable decelerations intrapartum. But what if the patient has suspected IAI? Is that a relative contraindication for amnioinfusion? Is that safe? In this episode we will examine the data and provide some clinical insights.

In 2014, a publication out of JAMA Pediatrics raised questions regarding the safety of acetaminophen in pregnancy describing a possible “association” with later neurodevelopmental and cognitive delays in children. What followed was a string of controversial publications (observational) with mounds of conflicting data. This led to a controversial international consensus opinion in 2021 calling for “caution for use” regarding acetaminophen in pregnancy. The ACOG had a strong rebuttal to that statement at that time. But now, as of April 9, 2024, we have new data on acetaminophen/paracetamol use in pregnancy and possible neurodevelopmental affects in children. This new study was published out of JAMA network and followed 2.4 million children with sibling pairs out of Sweden. This is making a lot of news within the last 24 hours and it is hot off the press 🔥🔥🔥. Listen in, and find out more.

It has been stated that “Trauma is in the eye of the beholder”. Healthcare providers must be aware that a woman makes experience a birth as traumatic, even if she and her infant are healthy. The ACOG has highlighted perinatal PTSD in several publications, which we will review in this episode. Perinatal PTSD has definitely been in the OB/GYN and psychology literature with an increased frequency just over the last 3 months. In this episode, we will review the very real and devastating condition of perinatal PTSD, its diagnosis, and discuss interventions to reduce its development. We will also review new data on “service dogs“ detecting PTSD in people with trauma histories? NOTE: We will also highlight a real world account of a traumatic birth event from one of our podcast listeners (Deidentified, and shared with permission).

In July 2023 and again in November 2023, we discussed the “Rule of 55“ and its role in the management of hypertensive disorders of pregnancy. The Rule of 55 has been mainly applied in the selection of appropriate antipretensive medications when urgent/emergent hypertension is present. Does the Rule of 55 also work for antihypertensive management of gestational hypertension or preeclampsia without severe features? A new publication (April 1, 2024) from the AJOG MFM gives us that answer! In this episode, we will cover the newly released PYTT study from Italy.

On April 8, 2024, parts of the United States will be within the Path of Totality for the total solar eclipse. The state of Texas has already declared a state of emergency as visitors flock to the state to witness the event. This is a fascinating celestial occurrence that is not scheduled to happen again until August 2044. Does the eclipse have a negative effect on pregnancy? Do lunar cycles affect birth rates? What does the data say? Does NASA have a statement on this? And what are neutrinos?! Listen in… And find out. 🌖🌗🌑

Today, April 3, 2024, the ACOG released a clinical practice update to practice bulletin# 222 (gestational hypertension eclampsia). This is in direct response to a recent FDA approved biomarker test for risk stratification for preeclampsia. On May 19, 2023, the FDA cleared a novel biomarker serum test for the risk stratification for severe preeclampsia in hypertensive pregnant women. This clearance is the first given to any blood-based biomarker test for assessing preeclampsia risk. The company is Thermo Fisher Scientific (no disclosures). This new clinical practice update puts this test into proper perspective and gives clinicians some valuable insights of what it can, and what it cannot, do. Listen in for this “off the press” clinical practice update. 🔥🔥🔥🔥

According to the CDC, as well as worldwide data, the percentage of individuals categorized as overweight or obese is rising. First released in 1990 by the IOM, the guidelines for expected weight gain in pregnancy-based on pre-pregnancy weight (BMI)- have been controversial. These guidelines were revised in 2009. Now, a new publication from the Lancet (28 March 2024), is questioning the validity of the “minimal weight gain” recommended for patients with obesity. In this episode, we will review this controversy. Additionally, we will highlight a separate publication from the AJOG MFM (systematic review and meta-analysis) discussing NPWT use at C-section for patients with obesity.

The current dose and schedule for antenatal corticosteroids (ACS) follows the original publication by Liggins and Howie in 1972. That dose and schedule was based on sheep models from the 1960s. The dose in current use had never been evaluated to minimize exposures while assuring efficacy. New pharmacokinetic and pharmacodynamic data is calling into question whether the current dose and schedule is necessary. Translational research in animal models indicate that a constant, low concentration fetal exposure to ACS is sufficient for lung maturation, resulting in lower fetal exposures. In this episode, we will summarize a new clinical commentary published in AJOG in March 2024 highlighting the current state and controversies regarding ACS for threatened preterm labor.

Meningiomas are common intracranial tumors with a female predominance. The vast majority of these tumors are benign (World Health Organization [WHO] grade 1) while 15% to 20% of these tumors can behave atypically (WHO grade 2) and rarely, in 1% to 2% of cases, these tumors can be malignant (WHO grade 3) Their etiology is still poorly documented. The role of sexual hormones has long been proposed, but data have been conflicting across studies. However, a dose-dependent relationship between the incidence and growth of meningiomas and hormonal treatment with the synthetic progestin cyproterone acetate (CPA) has been recently established (2021). Now, a new observational study from France (BMJ) has raised the warning flag for a similar association with a common birth control option, depo medroxyprogesterone acetate. Does Depo-Provera cause brain tumors? It's very important to put this study into proper context. We’ll explain all of this, and more, in this episode.

According to the ACOG, pre-labor rupture of membranes (PROM) complicates 10% of all births in the United States and is a major contributor to perinatal morbidity and mortality. What is the best course of action when patients present with PROM with a “unfavorable cervix”? Should it be a pharmacological method of ripening, or a mechanical? What does the data say? In this episode, we will do a deep dive into published data from the 1980s up to 2023. We will also explain why the Bishop score “is irrelevant“(SOGC) in patients at term with PROM. 😳. The literature does favor one pharmacological agent in cases of PROM. Curious? Listen in and find out more.

Obstetrical vacuum and forceps are incredible tools, when used correctly, to assist vaginal delivery. Appropriately selected and used, they can be pivotal in reducing the number of unnecessary cesareans and potentially decreasing certain fetal and maternal complications. However, there are several pearls of wisdom to remember when using them. In this episode, we will focus on a rare – but potentially fatal – complication of vacuum use: subgaleal hemorrhage. Although subgaleal hemorrhage can occur following normal birth processes, and even cesarean section, vacuum use is the strongest independent factor for its occurrence. In this, we will review these pearls of wisdom and the importance of detecting neonatal subgaleal hemorrhage quickly.

Ovarian preservation by autologous transplantation has given hope to patients desiring future fertility after certain gonadotoxic therapies for malignant conditions. But now, the same procedure is being promoted as a “natural cure” for menopause. Can ovarian tissue-based therapies really be the female, endocrine “fountain of youth”? In this episode, we will highlight a recent publication from the AJOG describing the potential of this procedure. We will also discuss the history of ovarian autotransplantation and why this procedure for menopause prevention has more questions than answers.

Since the late 1990s, the standard practice for GDM care has been to measure postprandial glucose values. For patients with pre-gestational diabetes, whether type I or type II, the ACOG recommends multi-level glucose checks (fasting, pre-meal , postprandial, and nighttime). But what about in the immediate postpartum interval? In patient’s with pre-existing diabetes, should blood sugars be checked pre-meal (qAC) or postprandial while still in the hospital, and after discharge? The topic for this episode comes from one of our podcast family members who had this clinical dilemma? In this episode, we will review the data and recommendations from the American Diabetes Association, the ACOG, and CDC. So grab your sugar-free drink of choice, and listen in!

Is breastfeeding with Hepatitis C safe? The answer: Yes! But confusion persists today mainly surrounding the serum hepatitis C viral load. That’s the topic and focus of the new publication released March 2024 in the Green journal, Obstetrics and Gynecology. We will highlight this new study in this episode. Yep, we have learned a lot about hepatitis C, and HIV, and breast-feeding. In this episode, we will review: the different hepatitis C genotypes and their implications, current breast-feeding guidelines for women with hepatitis C, the updated guidelines for breast-feeding with HIV, how some may be spontaneously “cured” of hep C postpartum, and why viral load matters for one of these conditions – but not the other!

It has been estimated that up to 4.4% of the US adult population has been diagnosed with ADHD. Use of ADHD medication is increasing among pregnant women. In the last several years, there’s been a litany of publications looking at the effects of pregnancy on ADHD, as well as the effects of medication on the pregnancy. In this episode, we will highlight a new publication released March 2024 (Archives Women’s Mental Health) examining prenatal outcomes in women who continued dexamphetamine in pregnancy. We will also summarize the data regarding the effect of ADHD medication on congenital anomalies and neurodevelopmental outcomes in the children.

Four years, the US National Vital Statistics System has reported an abnormally high maternal mortality rate in the United States, showing it to be nearly doubled from 17.4 in 2018 to 32.9 per 100,000 live births in 2021. The United States’s maternal mortality rate has been on the media radar for many years because of this. But that rate is completely WRONG. How is it that maternal mortality rates are more than 2 to 3 times higher than other developed countries despite our vast progress in obstetrical care? The answer? It is a statistical error! In this episode, we will review a brand new publication from the AJOG published on March 12, 2024 that is making media headlines. We have known that this reporting system is greatly flawed for several years, and now it is getting the attention it deserves. Although this is reassuring news for the country overall, there is still ONE patient demographic where we need to dramatically reduce the maternal mortality rate. Curious? Listen in and find out more.

The ACOG, CDC, and WHO currently do not recommend universal screening for thrombophilia in the general population before starting oral contraceptive pills. However, a new publication in AJOG (March 2024) is challenging that stance. In this episode, we will review this new prospective population-based study to see if it makes the case for universal screening for thrombophilia variants before starting OCPs. In this episode, we’ll also discuss high-risk versus low-risk thrombophilia, discuss relative risk versus absolute risk of VTE on the combination pill, and give clear clinical implications for patient management.
