Ninja Nerds,
Welcome to the Ninja Nerd Podcast with Zach and Rob! In this episode, we explore Amyloidosis, a complex disorder characterized by the misfolding and deposition of insoluble amyloid fibrils in tissues. We break down the different subtypes, including AL (light chain), AA (secondary), ATTR (transthyretin), and Aβ2M (β2 microglobulin), highlighting their unique pathogenesis, clinical manifestations, and diagnostic approaches.

Our discussion covers the systemic vs. localized forms of the disease, exploring how amyloid deposition can impact critical organs like the heart (restrictive cardiomyopathy), kidneys (nephrotic syndrome), nervous system (autonomic and peripheral neuropathy), and gastrointestinal tract. We also walk through essential diagnostic tools, including serum and urine electrophoresis, fat pad biopsy with Congo red staining, mass spectrometry, and advanced imaging techniques like cardiac MRI and PYP scanning for ATTR amyloidosis.

Finally, we break down the latest treatment strategies, from chemotherapy and autologous stem cell transplant for AL amyloidosis. Whether you’re preparing for exams, rotations, or just want to master this challenging topic, this episode is packed with high-yield insights to boost your understanding!

$Inflammatory Bowel Disease (IBD) | Clinical Medicine 📚 Premium Notes, Illustrations, Slides & Quiz for IBD: https://www.ninjanerd.org/lecture/inflammatory-bowel-disease-ibd-crohns-ulcerative-colitis-usmle-step-2-rapid-review Ninja Nerds! In this lecture, Professor Zach Murphy will present on Inflammatory Bowel Disease (IBD). We will discuss the pathophysiology, including the chronic inflammation of the gastrointestinal tract seen in conditions like Crohns Disease and Ulcerative Colitis, and the clinical manifestations that may include abdominal pain, diarrhea, and weight loss. The session will transition to a digital presentation focused on the diagnostic approach, highlighting endoscopy, colonoscopy with biopsy, and imaging studies. Finally, we will review the management strategies for IBD, emphasizing pharmacotherapy with anti-inflammatory and immunosuppressive agents, as well as surgical options for refractory disease.

$COVID-19 | Podcast 🌐 Official Ninja Nerd Website: https://ninjanerd.org Ninja Nerds! In this episode of the Ninja Nerd Podcast, Zach and Rob walk you through a high-yield, case-based approach to COVID-19, built exactly the way you need it for exams and real clinical decision-making. Using three core cases, we break down how to recognize the disease, build a systematic diagnostic approach, and most importantly, match treatment to severity so you know exactly what to do in the moment. We start by building the clinical foundation with a patient presenting with early symptoms like fever, cough, and loss of taste. In this case, we walk through the pathophysiology of SARS-CoV-2, focusing on its spike protein binding to ACE2 receptors and how this explains the multisystem involvement seen in COVID. You will learn how infection progresses through distinct phases, from early viral replication to pulmonary disease and finally to the hyperinflammatory state that drives severe complications like acute respiratory distress syndrome and multiorgan failure. Next, we expand this framework by connecting pathophysiology to clinical complications. We break down why patients develop diffuse alveolar damage and refractory hypoxemia, as well as the hypercoagulable state that leads to deep vein thrombosis, pulmonary embolism, and stroke. We also highlight high-yield complications, including acute kidney injury, myocarditis, and long COVID, emphasizing the key clinical clues that help you recognize them quickly. From there, we shift into a systematic diagnostic approach using a high-risk patient with known exposure. You will learn how to choose between polymerase chain reaction testing and rapid antigen testing, when negative results require repeat testing, and how the physical exam becomes a critical tool for severity classification. We also walk through when to order laboratory studies and imaging, including inflammatory markers, coagulation studies, chest imaging, and arterial blood gases, and how each result directly informs clinical decision-making rather than just adding data. Finally, we bring everything together with a step-by-step treatment framework based on disease severity. Through a progression of cases, we show how to manage mild to moderate disease in high-risk outpatients with early antiviral therapy, how to treat severe disease with oxygen support, corticosteroids, antivirals, and anticoagulation, and how to escalate care in critical illness with advanced respiratory support and immunomodulators. We also cover key monitoring pitfalls, including drug interactions, hepatotoxicity, and complications of therapy. We close with a focused review of prevention strategies, including vaccine mechanisms and the role of pre-exposure prophylaxis in select immunocompromised patients, tying everything together into a practical framework you can use on exams and in the hospital.
