À propos de ce contenu audio

 Forget everything you ever read in a textbook when it comes to antimicrobial resistance (AMR) and sepsis complications – because they rarely play by the rules. They evolve, adapt, and strike before it’s too late. While classic symptoms like fever, tachycardia, and hypotension are well known, the real challenge lies in recognizing the unexpected to reduce your mental list of those unknown, unknowns. Hosted by Critical Care RN & CNS Author Nicole Kupchik, The Sepsis Spectrum is an exploration of real-world patient cases, expert insights, and clinical deep dives to unravel the most complex presentations facing modern medicine.

    • When Sepsis Hits the Lungs

      When Sepsis Hits the Lungs
      Dec 23 2025
      Sepsis doesn’t just overwhelm the body, it can turn the lungs into ground zero for multi-organ dysfunction. In this episode, host Nicole Kupchik sits down with Dr. Julie Bastarache to explore how sepsis triggers Acute Respiratory Distress Syndrome (ARDS) in a significant portion of critically ill patients. Dr. Bastarache explains why sepsis-induced ARDS isn’t a single entity but a spectrum of clinical, physiologic and biologic responses, each requiring its own approach. From the fundamentals of mechanical ventilation and why low tidal volume remains lifesaving, to the emerging, and surprising protective effects of GLP-1 receptor agonists, Dr. Bastarache’s reverse translational science bridges bedside observations back into the lab, to uncover new pathways and potential therapies. Plus, mental health counselor Kristan Seaford, shares her Sepsis Survival story of how pushing through the holiday season while caring for children sick with strep and the flu, led her to overlooking her own symptoms until she was fighting for her life. Featured Guests: Julie Bastarache, MD (@JulesBass6), is a physician scientist who specialized clinically in pulmonary and critical care medicine. She cares for patients in the intensive care unit who have a variety of life-threatening problems including pneumonia, sepsis (a severe infection that causes organs to shut down), respiratory failure, and shock. Despite advances in ICU care, many patients admitted to the ICU die and those that survive often have permanent problems like kidney failure, trouble thinking, weakness, and low oxygen levels. Key Takeaways: Sepsis damages the lungs in 30-40% of patients making ARDS one of the most visible and deadly expressions of systemic inflammation. ARDS is not a single disease, it's driven by a cascade of mechanisms ranging from mechanical, physiologic and biologic failure all at once. High-flow nasal cannula is a powerful bridge therapy. It supports oxygenation and may prevent intubation, especially useful in COVID-19 related ARDS. The best ventilator mode is the one clinicians understand well. Simplicity and mastery often outperform switching to complex modes, especially considering low tidal volume ventilation has been proven as a mortality-reducing ventilation strategy. GLP-1 receptor agonists show promise in protecting organs during sepsis. Patients on these medications appear less likely to develop sepsis or organ injury, mouse models confirm improved survival The future of sepsis and ARDS lies in precision medicine, moving away from broad labels towards targeted categories that enable more effective and individualized treatments. — Get in Touch: info@sepsis.org Or Visit Us At: SepsisPodcast.org Connect with Nicole on Socials: @nicolekupchik Connect with Sepsis Alliance on Socials: @sepsisalliance To Learn More About Sepsis, Visit Sepsis.org Produced by: Human Content and Sepsis Alliance Sepsis is a life-threatening emergency that happens when your body’s response to an infection damages vital organs and, often, causes death.

    • What happens to the kidneys during sepsis?

      What happens to the kidneys during sepsis?
      Dec 16 2025
      Acute kidney injury (AKI) is far more dangerous and complex than previously understood. In this episode, host Nicole Kupchik sits down with Dr. Gonzalo Matzumura to break down what really happens inside the kidneys during sepsis. From disrupted renal perfusion, tubular cell injury, and overwhelming inflammation, clinicians and, more importantly, patients, face high stakes when it comes to treating sepsis-related AKI. Dr. Matzumura sheds light on why prevention, recognition, and calling in the nephrologist earlier can mean the difference between lifelong disease, kidney replacement therapy, and full recovery. We’re also joined by Josh and Chelsea Woodward who share their powerful sepsis survival story, recounting how just a few red spots on Josh’s skin quickly spiraled into a medical crisis, underscoring just how quickly AKI and sepsis can escalate and why awareness is essential. Featured Guests: Gonzalo Matzumura Umemoto, MD,(@GMatzumura) is an Assistant Professor of Medicine in the Division of Nephrology at Washington University School of Medicine. He serves as the Director of Acute Dialysis Services at Barnes-Jewish Hospital. Key Takeaways: Nearly 45-70% of acute kidney injuries in the ICU are linked to sepsis, making early recognition critical for improving survival. Kidney-toxic medications used during sepsis treatment (vancomycin, gentamicin, amphotericin, vasopressors) can worsen AKI, requiring careful dosing and monitoring. Creatinine levels lag 24-48 hours, meaning kidney injury is often detected too late; clinicians need better biomarkers and early monitoring. Fluid resuscitation requires balance. Overload can precipitate the need for kidney replacement therapy, especially in oliguric patients. Sepsis-related AKI is multifactorial, involving inflammation, immune activation, microcirculatory dysfunction, and in some cases, mitochondrial injury. — Get in Touch: info@sepsis.org Or Visit Us At: SepsisPodcast.org Connect with Nicole on Socials: @nicolekupchik Connect with Sepsis Alliance on Socials: @sepsisalliance To Learn More About Sepsis, Visit Sepsis.org Produced by: Human Content and Sepsis Alliance Sepsis is a life-threatening emergency that happens when your body’s response to an infection damages vital organs and, often, causes death.

    • Is the gut the real engine of sepsis?

      Is the gut the real engine of sepsis?
      Dec 9 2025
      Host Nicole Kupchik is joined by Dr. Kaveh Hoda to unpack one of the most overlooked drivers of sepsis: the gut. Often called “the motor of MODS,” the GI tract can push the body toward recovery, or accelerate systemic collapse. In this episode, Dr. Hoda explains the importance of microbiome diversity, the breakdown of gut barriers leading to leaks and inflammation, and how critical illness disrupts the small intestine. More importantly, he shares what clinicians can do to support GI function at the bedside, from early nutrition strategies and listening to bowel sounds, to C.diff management. Plus, Sepsis Survivor Hailey Bain shares her story of septic shock, which was triggered by a ruptured appendix and originally mistaken for gynecologic pain. Her experience highlights how sepsis can escalate if early warning signs are missed. Featured Guests: Kaveh Hoda, MD, Gastroenterologist, Hepatologist and Host of The House of Pod Twitter @thehouseofpod BlueSky @KavehMD Key Takeaways: The gut is a central driver, not a bystander in sepsis. The GI tract can ignite systemic inflammation, worsen organ failure, and shape overall prognosis. Critical illness rapidly destroys microbiome diversity. Within days in the ICU patients lose microbial variety, a major blow to immunity, mucosal integrity, and gut resilience. Even good bacteria can become harmful. Under stress and illness, bacteria that were once benign can act more virulent and contribute to sepsis progression. Antibiotics, proton pump inhibitors, and ICU stress can compound damage. While necessary interventions, they also accelerate microbiome disruption, making the gut even more vulnerable Clostridioides difficile, formerly known as clostridium difficile (C.diff) thrives when the microbiome collapses, however fecal microbiota transplant (FMT) has been changing the game. The transplant remains one of the most effective modern treatments for recurrent C.diff in critically ill patients. Sepsis survivors can struggle with long-term gut and nutrition problems. Muscle wasting, anorexia, IBS, malnutrition and increased infection risk require holistic post-ICU care and high protein nutrition. — Get in Touch: info@sepsis.org Or Visit Us At: SepsisPodcast.org Connect with Nicole on Socials: @nicolekupchik Connect with Sepsis Alliance on Socials: @sepsisalliance To Learn More About Sepsis, Visit Sepsis.org Produced by: Human Content and Sepsis Alliance Sepsis is a life-threatening emergency that happens when your body’s response to an infection damages vital organs and, often, causes death.
