Your Nervous System Is the Vital Sign Nobody Is Checking Blood pressure. Heart rate. Respiratory rate. These are the numbers medicine has built its entire screening system around. But what if the thing driving all of those numbers, the autonomic nervous system, is never actually assessed? Dr. Terri sits down with returning guest Jim LaValle — internationally recognized clinical pharmacist, board-certified clinical nutritionist, and founder of the Metabolic Code platform — for a conversation that connects dots most clinicians never connect. The nervous system as a root driver of cardiovascular disease, thyroid dysfunction, gut permeability, autoimmune disease, blood sugar dysregulation, and sleep failure. If you're doing all the right things and still not getting results, this episode may be the missing piece. They cover heart rate variability, what your wearable data is actually telling you, why 60% of people who die of a heart attack have no arterial disease present, and the specific supplements, adaptogens, theanine, holy basil, phospholipids, aged garlic extract, that can begin to calm a chronically activated sympathetic nervous system while you work on the root cause. This is a masterclass in practical nervous system medicine. Bring a pen. What you'll discover: Why heart rate variability is as important as blood pressure — and what it tells you about your cardiovascular risk [20:21] The shocking stat: 60% of people who die of a heart attack have no arterial disease present. What is actually killing them [22:22] How chronic sympathetic dominance suppresses T3, causes gut permeability, triggers autoimmune thyroiditis, and disrupts sleep — all from the same root cause [44:45] How to use your wearable data practically: what to look at in the morning, how to read your sleep data, and why your sleep score may be lying to you [50:32] Box breathing vs. meditation: why they are two different tools that work best together — and how to know when you've actually arrived in that meditative state [35:12] Why 5am boot camp may be the worst thing you can do for your nervous system — and what to do instead [59:15] The supplement protocol for calming sympathetic dominance: theanine, loric acid, holy basil, kava, phospholipids, magnesium threonate, and Kyolic aged garlic extract [1:12:24] How blood sugar directly drives sympathetic tone — and why people with diabetes almost always end up with heart disease [1:01:58] Why childhood stress and prenatal maternal stress can hardwire sympathetic dominance into the nervous system before a child is even born [1:06:13] You cannot optimize what you have not calmed.

We recently made some cervical spine immobilization protocol changes here at MCHD. Dr. Patrick and Dr. DePasquale discuss the history and literature that provide the foundation for rigid cervical collar use, along with the new MCHD protocol implementation. This has been a collaborative process with our local hospital partners, which has definitely involved give-and-take on both sides. REFERENCES 1. Davies G, Deakin C, Wilson A.

Propofol remains a cornerstone sedative for mechanically ventilated critically ill patients and is supported by PADIS guidelines and favored for its rapid onset, titratability, and limited side effects. However, its use in hemodynamically unstable patients remains a persistent clinical dilemma. In this episode of the Society of Critical Care Medicine (SCCM) Podcast, host Kyle Enfield, MD, is joined by Scott Benken, PharmD, MHPE, BCCCP, and Nathan Smischney, MD, MS, to explore the risks, benefits, and evolving evidence surrounding propofol use in this high-risk population. The discussion examines the physiologic basis of propofol-associated hypotension and how that can manifest in different patients, such as those with sepsis and septic shock. Patient selection and real-time assessment of hemodynamic trends are essential. Additional considerations include the recognition of and monitoring for propofol infusion syndrome, a rare but life-threatening complication. The episode also explores alternative drugs such as dexmedetomidine and ketamine, highlighting the benefits and risks of each. Emerging strategies are discussed, including a ketamine-propofol combination called ketafol and its utility in balancing sedation and hemodynamic stability. Listeners will gain expert insights into propofol use in the ICU and a deeper understanding of patient-centered approaches to sedation.

This episode is a teaser for RACP LIFT 2026, a series of in-person events to promote Learning, Innovation and Forward Thinking. Coming up on the 1st of August in Melbourne there will be a Rapid Fire Clinical Update on Respiratory medicine, infectious diseases and critical illness. And on the 20th In Brisbane another one themed around Palliative medicine and also population health. In March, the Sydney RACP offices hosed a meeting on cardiometabolic and vascular health, and the talk shared here covers everything a generalist needs to know about metabolic dysfunction-associated fatty liver disease. The seminar was presented by Professor Jacob George, Director of the Storr Liver Centre at the Westmead Institute for Medical Research, and author of over 1300 peer-reviewed papers. He explains why fatty liver disease is a "canary in the coal mine" for metabolic health more generally, how to diagnose using scans and bloods, and the use of the FIB-4 index. Professor George also describes how patients can be stratified and managed for risk of more complex liver disease and reviews outcomes from the latest pharmacological interventions.

While the gut microbiome often steals the spotlight, the microorganisms residing in our respiratory tract play a vital role in our health and immunity. In this episode, Dr. Sheena Fraser sits down with microbial ecologist Dr. Michael Cox to explore the fascinating, complex, and relatively uncharted territory of the lung microbiome.They discuss how the lung microbiome fundamentally differs from the gut, the daily flux of bacteria entering and leaving our airways, and the profound impacts of environmental factors like air pollution, smoking, vaping, and household cleaning products. Plus, Dr. Cox shares the massive challenges scientists face when studying these deep-tissue microbes and what the future of respiratory medicine might look like.What We Cover:From Seawater to Sputum: Using marine ecology techniques to decode human respiratory biology.Exploring the lungs' dynamic balance of microaspiration and mucociliary clearance.Meet the core lung bacteria (Streptococcus, Prevotella, Veillonella) and the puzzle of anaerobes in an oxygen-rich space.Environmental Disruptors: How pollution, smoking, and vaping inflame and alter the lung microbiome.Hidden Dangers of VOCs: The silent impact of everyday cleaning sprays and aerosols on respiratory health.Diet, Exercise, & Epigenetics: The systemic benefits of a high-fiber diet and fitness for chronic lung conditions like COPD and asthma.About Dr. Michael Cox is a microbial ecologist and the PGR Lead for the Institute of Microbiology and Infection at the University of Birmingham. His research focuses on the bacteria that reside in the respiratory tract in the context of respiratory diseases (such as COPD and Cystic Fibrosis). His lab works to understand the function of the respiratory microbiome, translate these findings for clinical benefit, and expand our understanding of the respiratory ecosystem beyond just bacteria.Connect with Dr Michael Cox:University of BirminghamScientific References & Further Reading:Cumming, K.

Arreaza: Welcome back tothe Rio Bravo qWeek Podcast! My name is Dr. Hector Arreaza, I am a family physician and faculty member in the Rio Bravo Family Medicine Residency Program. Today I am joined by two excellent medical students who will introduce themselves now, welcome, guys! Mehr: Thank you for the introduction! My name is Mehr Boparai, third year medical student at WesternU COMP-NW. Jeremy: And my name is Jeremy Pan, also a third-year medical student at WesternU COMP Pomona and we will be discussing a very prevalent topic today in the clinical world that is arguably becoming one of the biggest threats to modern medicine: antibiotic resistance. Mehr: That's right! Imagine this scenario: a routine infection, something we've treated easily for decades, suddenly becomes life-threatening because the drugs we always thought we could rely on just don't work anymore. You likely ran into this problem just last week with one of your patients! That's not science fiction. That's happening every day in hospitals across the world. Dr. Arreaza: I agree, antibiotic resistance must be taken seriously. I increased my awareness in 2023, when I attended a medical research conference in Carmel(which is a popular conference that takes place in that beautiful town). I heard Dr. David Gilbert, a famous and accomplished ID doctor who helped develop the Sanford Guide to Antimicrobial Therapy, he warned everyone about antibiotic resistance as one of the biggest threats for humanity, the other two were a nuclear bomb and an epidemic. Jeremy: Woah, comparing antibiotic resistance to a nuclear bomb is absolutely crazy, but likely very real!! Well today, we're going to be focusing on five of the most common infections or “bugs” you'll see in a hospital setting. We'll talk about what typically causes them, what antibiotics we used to rely on, and what happens when resistance decides to enter the picture. Mehr: If you are a medical student (or resident), you understand that dreaded feeling when an attending asks “what antibiotics should we start?” But don't worry, in this episode, we hope to address the decision-making process in a simple framework. What is Antibiotic Resistance? Dr. Arreaza: Before we jump into specific common infections and pathogens, let's cover our basics. Antibiotic resistance occurs when bacteria evolve to survive drugs designed to kill them. This can happen through genetic mutations or by getting resistance genes from other bacteria. Why does this matter? Jeremy: It matters because antibiotics play a huge role in modern medicine. Without them, surgeries, chemotherapy, organ transplants—even childbirth—become significantly more dangerous. Mehr: According to the CDC, in the U.S. alone, antibiotic-resistant infections affect over 2.8 million people each year and cause more than 35,000 deaths! So, when we talk about resistance, we're not just talking about inconvenience for treatments. We're talking about a fundamental threat to healthcare. Staph aureus Dr. Arreaza: So, if you have a patient who comes in with a skin infection or is maybe showing signs of pneumonia or bacteremia, what is one of the most common bugs that you should think about? Jeremy: Staph aureus! Typically to treat methicillin-sensitive strains (MSSA), we would utilize antibiotics like nafcillin, oxacillin, or cefazolin. But there is one strain in particular that is worrisome, Mehr? Mehr: yeap, that would have to be MRSA, one of the most well-known resistant organisms. MRSA is resistant to all beta-lactam antibiotics, which means we can say goodbye to all penicillin and most cephalosporins. Dr. Arreaza: And what is the first antibiotic that comes to mind if we see MRSA on a culture in the hospital? Mehr: Vancomycin! Alternative treatments include linezolid and daptomycin depending on the type of infection. But what is the problem that we are starting to see? Jeremy: You guessed it, cases of resistance to vancomycin are starting to appear—VRSA. These cases are still uncommon today, but these findings show a worrying trend, that we will eventually start running out of reliable options. Dr. Arreaza: Fortunately, VRSA infections are extremely rare, with only 14-16 documented cases in the United States. As of 2019, 52 VRSA strains have been identified in the United States, India, Iran, Pakistan, Brazil, and Portugal. Let's keep an eye on VRSA in the future. E. coli Dr. Arreaza: Alright, so let's say you have a patient with dysuria, urinary frequency, maybe even a catheter in place. What's the most common bug you're thinking of? Mehr: That one's a classic, we are thinking E. coli. Jeremy: Exactly. E. coli is the leading cause of urinary tract infections, especially in both community and hospital settings. Dr. Arreaza: So Jeremy, what are we using for uncomplicated UTIs? Jeremy: We usually think of trimethoprim-sulfamethoxazole, nitrofurantoin, or sometimes fosfomycin. And in more complicated cases, we might consider fluoroquinolones like ciprofloxacin. Mehr: But here's where things get tricky. Resistance to TMP-SMX and fluoroquinolones has been increasing significantly. In some areas, resistance rates are over 20–30%, which really changes your empiric choices. Conclusion: Dr. Arreaza: So we've talked about five major organisms today: Staph aureus, E. coli, Klebsiella, Pseudomonas, and C. diff. What's the overarching takeaway of the discussion? Jeremy: The main takeway is that antibiotic resistance is already here, and it's affecting some of the most common infections we see in clinical practice on a day-to-day basis. Mehr: And as students and future physicians, it's important to not just memorize antibiotics, but understand why we're choosing them. Dr. Arreaza: Exactly. Always think: What organism am I targeting? What are the local resistance patterns? And can I narrow therapy once I have cultures? Jeremy: And maybe most importantly—don't overuse antibiotics, especially in cases when they're not needed. Mehr: Because the more we use them, the faster we lose them. Dr. Arreaza: I'd like to share the story I listed to in a RadioLab episode about Dr Steffanie A. Strathdee, one of the most influential ID doctors in the world and Co-Director at the Center for Innovative Phage Applications and Therapeutics (IPATH). She shared that her husband got infected by Acinetobacter baumannii, an opportunistic infection that can cause severe infection. After trying many antibiotics, he was treated with “phages”, “bacteriophages”. So, that's part of “thinking out of the box”. Jeremy: Thank you all for tuning in to the Rio Bravo qWeek podcast series and thank you Dr. Arreaza for having Mehr and me on the podcast today! Stay informed, stay curious—and we'll see you next time Mehr: Guys! I had so much fun! We hope this episode helped simplify antibiotic selection for the most common infections and bugs seen in a hospital setting and gave you a framework you can for initial treatments and cases of antibiotic resistance. Thanks for hanging out with us! Dr. Arreaza: And remember, antibiotics are one of the most powerful tools we have in medicine. Let's use them wisely.

In this episode, I sit down with respiratory and sleep scientist Martin McPhilimey to take a deep dive into breathing, CO₂ regulation, and how they actually impact performance, stress, and sleep. We get into why respiratory physiology is way more complex than most people think, how his clinical and research background shaped his approach, and why breathwork exploded during COVID with names like Wim Hof and James Nestor. From there, we dig into allostatic load and why piling on high-stress practices—like aggressive hyperventilation or cold exposure—can backfire if you're already running hot. We also talk about the difference between actually relaxing your system versus just dissociating from it. We cover how inspiratory muscle training can improve performance and recovery, why respiratory rate is one of the most sensitive markers of stress, and question some common ideas, such as “CO₂ tolerance.” We also touch on the risks and limited data around inhaled CO₂ therapies and what actually makes sense to apply in the real world.

Send us Fan MailIn this episode of Never Been Sicker, Michael Rubino sits down with Dr. Richard Wallace, MD, a longtime urgent care physician, to talk about what he's seeing on the front lines of modern illness. Richard shares why urgent care appealed to him, how medicine is really detective work, and why post-2020 illness patterns have become far less predictable than they used to be.The conversation dives into root-cause medicine, chronic illness, allergies, mold exposure, and why so many people are stuck in symptom management instead of actually solving the problem. Dr. Wallace explains how basic foundations like sleep, movement, hydration, food, and clean air play a major role in long-term health, and why he believes many common issues are more reversible than people are told.The episode also covers environmental triggers, blood pressure, cholesterol, sleep quality, and the way insurance and conventional systems can sometimes get in the way of better care. It is a practical, wide-ranging conversation about what is really making people sick and what people can start doing differently.Timestamps00:00 Intro + meet Dr. Rich Wallace00:33 Why he chose urgent care01:45 Medicine as detective work02:19 Illness vs. injury trends03:02 Why winter brings more illness03:34 Indoor air + HVAC discussion04:42 Why being indoors impacts health05:17 Common summer injuries06:16 Are we getting sicker?07:04 Why illness is less predictable now09:31 Immune system discussion10:16 Urgent care becoming primary care11:17 How to be proactive with health12:16 Importance of annual labs13:14 Catching issues early14:12 Real patient example15:16 Why root cause matters16:02 Problems with current care models17:08 Insurance limitations18:52 Chronic illness + hidden triggers19:49 Mold + migraine case21:16 Why mold is often missed22:03 Why we feel sicker today22:42 The body's ideal range23:33 Weight + chronic illness24:05 Sleep importance25:03 Phone use + sleep disruption25:54 Lack of movement26:52 Dehydration27:35 Nutrition habits28:19 Air quality added29:06 Sedentary lifestyle30:06 Morning routines31:07 Clean air + breathing31:40 Respiratory system priority32:02 Exercise + hydration link32:57 Daily routine + diet35:35 Sleep improvements37:45 Temperature + sleep40:06 Staying updated in medicine41:29 Lymphatic + glymphatic systems43:22 Sleep + brain health44:51 Biggest lie: hypertension45:25 Weight + blood pressure47:13 Solving root causes48:18 Cholesterol debate49:34 “Water vs. milkshake” analogy50:32 Diet misconceptions51:57 Simple nutrition approach53:12 Where to find Dr. Wallace54:02 Outro-----------------------------------------------------------------------------------------------

We’re excited today to launch our first episode in collaboration with the Irish Thoracic Society and their podcast series. The Irish Thoracic Society represents respiratory professionals throughout Ireland and is dedicated to championing excellence in the prevention, diagnosis, and clinical care of respiratory disease through its work in advocacy, education and research. In today’s episode, we explore the complex and often overlooked world of refractory chronic cough — a condition that can significantly impact patients' quality of life but is frequently misunderstood or underdiagnosed. With insights from leading respiratory specialists in Ireland and the United States, we discuss the latest thinking on diagnosis, management, and emerging treatments aimed at improving outcomes for patients and helping clinicians navigate this challenging area of respiratory medicine. Joining us are renowned experts Professor Lorcan McGarvey and Professor Brendan Canning, both internationally recognised leaders in respiratory medicine and cough research. Together, they share their perspectives on the neurobiology of chronic cough, the considerable morbidity experienced by patients, and how clinicians can approach diagnostic investigations more effectively. We also explore current treatment strategies and promising new therapies on the horizon as chronic cough increasingly gains recognition as a disease in its own right — rather than simply a symptom. Whether you’re a clinician, researcher, or simply interested in advances in respiratory medicine, this episode offers valuable insights into a condition that is finally receiving the attention it deserves.

J Am Coll Cardiol. 2026 Feb 19:S0735-1097(25)10161-7. doi: 10.1016/j.jacc.2025.11.005. Epub ahead of print. PMID: 41712898. Key Learning Points Why these guidelines matter: This is the first joint AHA/ACC clinical practice guideline specifically on acute PE, bringing together a truly multidisciplinary writing committee (cardiology, pulmonology, hematology, emergency medicine, interventional radiology, surgery, and others). Prior guidelines existed from individual societies, but nothing this comprehensive had been updated in roughly five to six years. New PE clinical categories (A through E): One of the most impactful changes is replacing the old “massive/submassive” and “low/intermediate/high risk” labels with five categories that form a severity continuum. Category A is subclinical (incidental PE found on imaging in asymptomatic patients). Category B covers symptomatic but low-severity patients. Category C is where much of the clinical complexity lives — symptomatic, hemodynamically stable patients subdivided into C1, C2, and C3 based on RV function and biomarkers. Category D represents incipient cardiopulmonary failure (transient hypotension, normotensive shock with end-organ dysfunction). Category E is frank cardiopulmonary failure, with E2 being the sickest — refractory or recurrent cardiac arrest. Respiratory modifiers (hypoxia requiring supplemental oxygen) layer onto C, D, and E. Diagnostic approach: Clinical evaluation comes first — history, exam, and validated decision tools (Wells score, revised Geneva, PERC). If clinical probability is low and D-dimer is normal, imaging can be safely avoided. If either is concerning, imaging is warranted. CTPA remains the preferred imaging modality due to superior sensitivity, specificity, wide availability, and ability to assess clot burden and alternative diagnoses. VQ scanning is still appropriate when CTPA is contraindicated, and VQ SPECT offers better reproducibility and specificity than traditional planar VQ if available. Echocardiography is not a diagnostic test for PE but is important for risk stratification — RV size, TAPSE, and tissue Doppler measures all contribute prognostic information. Anticoagulation updates: Anticoagulation remains the cornerstone of treatment. For patients potentially needing advanced therapies (C3, D, E), parenteral anticoagulation is started first. A notable recommendation: low molecular weight heparin is generally preferred over unfractionated heparin, based on evidence showing more effective VTE risk reduction, more predictable pharmacokinetics, no need for routine monitoring, lower rates of heparin-induced thrombocytopenia, and no increase in major bleeding. The committee acknowledged this may create discomfort for clinicians accustomed to unfractionated heparin’s easy reversibility, but the difficulty of achieving and maintaining therapeutic levels with UFH was a significant concern. Advanced therapies: Catheter-based thrombolysis, mechanical thrombectomy, systemic thrombolysis, and surgical embolectomy all received mostly class 2B recommendations (“can consider”) for C3 and D categories, reflecting that current evidence shows improvement in short-term surrogate measures (RV/LV ratio, hemodynamics) but lacks definitive hard outcome data on mortality. For category E1 patients, recommendations are stronger (class 2A). Multiple trials are expected soon — HI-PEITHO, PEERLESS-2, PE-TRACT, PERSEVERE, TORPEDO, and PROG — that should substantially inform future updates. PERT teams: Pulmonary embolism response teams are encouraged, particularly for C3, D, and E patients. They’ve been shown to reduce length of stay. For institutions without PERT capability, establishing consultation networks with larger centers is recommended. Post-PE follow-up: Patients shouldn’t be “left in the wilderness” after discharge. The guidelines recommend communication within the first week to ensure understanding of diagnosis and treatment, an in-person visit at or before three months to assess for persistent symptoms and discuss anticoagulation duration, ongoing surveillance for chronic thromboembolic pulmonary disease, and periodic reassessment for those on extended anticoagulation.

Severe vitamin D deficiency is linked to a sharply higher risk of hospitalization for respiratory infections such as bronchitis and pneumonia, turning common illnesses into serious medical events Adults with the lowest vitamin D levels face worse outcomes after pneumonia, including a much higher risk of dying months after hospital discharge, even when initial illness appears mild Higher vitamin D levels are associated with fewer everyday respiratory infections like colds and flu, reducing how often illness disrupts work, sleep, and daily life Vitamin D deficiency is widespread, often silent, and driven by limited sunlight exposure and modern indoor lifestyles, making it a correctable risk factor rather than an unavoidable one Combining systemic immune support from vitamin D with early, localized airway defenses helps stop respiratory infections from gaining momentum before they escalate

From choosing the right modality to knowing when it's time to escalate, this episode will help you support little lungs without jumping straight to the tube.
In this episode of Swallow Your Pride, Theresa sits down with Dr. Rabab Rangwala, PhD, CCC-SLP, to explore the science behind respiratory–swallow coordination in Parkinson's disease and what it means for clinical practice. They dive into how breathing patterns can influence swallowing safety, why patients with Parkinson's may not fully perceive their swallowing impairments, and what recent research reveals about the relationship between patient-reported symptoms and instrumental findings. Dr. Rangwala also shares how her clinical experience shaped her research questions and why instrumental assessment plays a critical role, while still recognizing real-world access barriers. This conversation bridges neuroscience and bedside care, offering practical insights to help medical SLPs strengthen their clinical clarity and better serve individuals with neurologic disease.

Her research focuses on the neural and behavioral control of swallowing and speech across healthy and clinical populations. Her work in dysphagia examines respiratory–swallow coordination, and objective assessment of swallowing impairments using wearable sensors, particularly in individuals with Parkinson's disease and other neurologic conditions. In parallel, she conducts speech neuroscience research using neuroimaging, psychophysics, and computational modeling to understand how the brain supports complex motor behaviors such as speech production. By integrating clinical insight with neuroscience and quantitative methods, Dr. Rangwala's work seeks to improve our understanding of speech and swallowing disorders, with the goal of informing healthcare delivery, guiding treatment decisions, and ultimately improving patient quality of life.
