This Is Why with Dr. Busti

Omega-3 fatty acids made easy: learn EPA vs DHA, how fish oil works, and when to use icosapent ethyl (Vascepa) in real clinical practice.

You’ll learn how to:

• What omega-3 fatty acids (EPA & DHA) are and how they work
• Fish oil (EPA vs DHA): what matters clinically (and what doesn’t)
• How omega-3s affect triglycerides and hypertriglyceridemia
• Icosapent ethyl vs “fish oil”: dosing, indications, and counseling

The goal = make medical education easy and clinically relevant.

Dive into the coagulation cascade with this clear, clinically focused review! In this lecture from This is Why, Dr. Busti breaks down the coagulation cascade in a clear, clinically relevant way—perfect for healthcare professionals preparing for exams or patient care. Dr. Busti specifically covers the basics of hemostasis, the intrinsic and extrinsic pathways, clotting factors, vitamin K-dependent factors, thrombin functions, and how the cascade leads to thrombus formation (including key differences between venous and arterial thrombi).
