😱 NIH Funding Predicts The Future Of Medicine #shorts

Want to know where medicine will be in 20 years? Follow the money. Specifically, where the NIH puts its dollars. Much of what’s now standard care began as federally funded research decades ago. Many of today’s billion-dollar therapies began as taxpayer-funded studies. But as of now, that same research investment is being questioned and cut. In this episode, we unpack the real ROI of public science, why pharma’s biggest wins often trace back to NIH discoveries, and what happens if that chain breaks with Dr. Mahmood Razavi.

🤯 The Therapy That’s Redefining ‘No-Option’ Patients #shorts

Every disruptive therapy comes with a fight. For DVA, that story was LimFlow, which built a new care paradigm, created new codes, and compelled the field to view “no-option” patients in a completely different light. Now, after two years off the market in Europe, LimFlow is back with next-gen stents and crossing devices. Access expands, adoption grows, and the debate gets louder: do we keep DVA only for “no-option” patients, or is it time to start treating poor-option cases too?

Lo que Nadie Dice Sobre la Arterialización Venosa del Pie – Parte 1 | LOF En Español

En este episodio solo de Life of Flow Podcast, hablamos sobre uno de los temas que más debate genera hoy en la cirugía vascular: la arterialización profunda venosa en pacientes con isquemia crítica de extremidades (CLTI). Partimos de un caso real de un paciente de edad avanzada sin opción quirúrgica convencional y conversamos sobre qué nos lleva a decidir entre un enfoque endovascular, abierto o híbrido. Compartimos cómo planificamos cada procedimiento, por qué el mapeo venoso del pie es clave y qué hemos aprendido de los errores, las complicaciones y la experiencia acumulada. También abrimos una reflexión más humana: ¿qué pasa cuando el resultado técnico no garantiza calidad de vida? ¿Cuándo es correcto seguir intentando y cuándo hay que aceptar otra realidad? ❗️Este episodio, grabado originalmente en inglés y ahora doblado al español, captura una conversación honesta sobre la evolución técnica y ética del tratamiento de la CLTI.
