Today is World Sickle Cell Disease Awareness Day! To acknowledge, I recommend the following: 1. Type “Tell me the most important thing to know about sickle cell disease in [your city]” into google or your preferred AI 2. Spread the word!

Jose de la Fuente showing data that has traditionally justified adult SCT in pts with sickle cell disease but not thalassemia — iron overload = GVHD = incr mortality. But does age become less reliable a surrogate marker for hemochromatosis in era of oral iron chelators?

Haydar Frangoul presenting on curative therapies for sickle cell disease, often performed in adults, makes a striking statement: these are patients who have been “sick” their entire lives. When they are suddenly free of disease, many are left wondering what to do with their lives, may feel lost

✍️We published a new topic page on medicine and biotechnology— For much of human history, people relied on trial and error to find cures for diseases and health conditions using natural plants and remedies, with little idea of which ingredients worked or why.
A timeline titled "The Golden Age of Antibiotics" shows when each antibiotic drug class was first available for medical use, with example antibiotics labeled. Classes are color-coded by their source: actinomycetes, other bacteria, fungi, or synthetic. Milestones include the first antibiotics (arsphenamines in 1910), as well as the discovery of many actinomycetes-derived antibiotics, such as streptomycin, and sulfonamides, penicillins, and tetracyclines. Data: Hutchings, Truman, Wilkinson (2019). Created by Saloni Dattani for Our World in Data.

Canada spends about $10 billion more on medicines each year than countries with universal pharmacare because our system doesn't provide access to medications through government-issued health cards.
