Dr. Chapa’s Clinical Pearls.

Postural Orthostatic Tachycardia Syndrome (POTS), first described in the 1940s, is a heterogeneous and often debilitating condition affecting the autonomic nervous system, estimated to affect between 0.3% and 1% of the U.S. population. Its incidence is believed to be rising among people with a prior COVID-19 infection, as a likely component of so-called long COVID. The condition is characterized by chronic orthostatic intolerance in the absence of orthostatic hypotension manifested as excessive increased heart rate upon standing. The etiology is not well understood but is thought to be complex. One recent publication described the complex etiology of POTS as, “A multitude of pathophysiologic mechanisms including but not limited to disproportionate sympathoexcitation, volume depletion, autoimmune dysfunction, cardiac and physical deconditioning point to a heterogeneously complex etiology”. Other POTS symptoms include fatigue, headaches, cognitive impairment, palpitations, chest pain and gastrointestinal symptoms. These symptoms can significantly reduce quality of life. Interestingly, most people with POTS are under age 50. In this episode we will review POTS in pregnancy. What therapies are available? Does anxiety have a role within this process? Listen in for details.

Hematuria remains one of the most common urologic diagnoses, estimated to account for over 20% of urology evaluations. Women with hematuria have been especially prone to delays in evaluation, often due to practitioners ascribing hematuria to a urinary tract infection (UTI) or gynecologic source, resulting in inadequate evaluation and delay in cancer diagnosis. In this episode, we will review the recently released joint guidance form the AUA and SUFU regarding microhematuria. What defines this condition? If a UTI is also diagnosed, does that end the investigation? And what are the 3 risk profiles for microhematuria? Listen in for details!

HOT HOT HOT Off the News CycleL The FDA has just approved (1 hour ago) a new at-home STI test kit. Does this work? What is the data on accuracy? What does this test for? This is a developing story... Listen in for details!

Metabolic syndrome (MetSyn) is a cluster of conditions, such as increase in waist circumference, dyslipidemia (elevated triglyceride levels and reduced HDL), increased blood pressure, and increased fasting blood sugar levels that is related to insulin resistance, diabetes, and elevated risk of cardiovascular disease. Women with PCOS have a significantly higher prevalence of metabolic syndrome (MetS) compared to the general population, with studies indicating a prevalence of around 43-47% in PCOS women. PLUS, there is a high prevalence of moderate to severe depressive symptoms and depression in adults and adolescents with PCOS; therefore, screening for depression in all adults and adolescents with PCOS is encouraged. In this episode, we will review a new publication for the J Clinical Endo & Metabolism discussing this combination (PCOS and depression/anxiety) and the MetSyn, and we will review the EXPANDED indications for metformin for metabolic syndrome prevention/treatment according to the 2023 PCOS updated guidance.

Throughout their lifetime, over 50% of women experience uUTIs, with recurrent infection reported in approximately 30%. Today, on March 25, 2025, the FDA approved a new first-in-class oral antibiotic for uncomplicated UTIs in women! This is Blujepa! In this episode, we will review the EAGLE clinical trial data and review the main side effects reported in the study population. How does this new antibiotic work? Will it be approved for pregnancy? And, what other genital condition could it likely be approved for? Listen in for details!

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, IUDs, and Inspiration”. Listen in for details.

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 cesarean delivery rates with discontinuation of pitocin in the active phase. Although the title of this new publication states, “Reduced risk of cesarean delivery with oxytocin discontinuation in active labor”, the devil is in the details! There's lots to review here, so listen in for details.

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 perspective are the core concepts highlighted in this episode. Listen in for details.

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 together with vomiting) and autism spectrum in the child. This is obviously a point of concern for those suffering with nausea slash vomiting in pregnancy. Is this association solid? What does the data show? It's controversial, but we will drive through it in this episode. PLUS, we will also highlight 2 recent publications (January 2025, February 2025 ) that provide some comfort for those suffering with these common symptoms. Listen in for details!

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 Ramadan have negative perinatal outcomes due to the potential caloric restriction? In this episode, we will highlight a Clinical Opinion publication from AJOG (June 2023) to examine the data.
