Hydroxychloroquine and COVID-19: What we know so far
Despite the current hype, infectious disease experts and others are cautious about using chloroquine drugs in the current COVID-19 pandemic. While the urgent need for COVID-19 treatments justifies the rapid pace of trials, several concerns have been raised related to the limitations of studies published so far. Kristin Moffitt, MD The drugs chloroquine and hydroxychloroquine ... Read More
Could plasma from recovered COVID-19 patients help others?
As new cases of COVID-19 mount daily, treatment revolves around supportive therapy to reduce symptoms, meaning there are no treatments shown to slow down or kill the SARS-CoV-2 virus. One new idea actually isn’t so new: transfusing blood plasma from recovered COVID-19 patients into patients currently sick with the disease. Last week, the Food and Drug ... Read More
100 years after the advent of TB vaccines, formulations vary widely
Each year, more than 100 million newborns around the world receive vaccinations against Mycobacterium tuberculosis, or TB, which infects about one-quarter of the world’s population. Facilities across the world produce several different formulations of these vaccines, known as Bacille Calmette-Guérin (BCG) vaccines. These are given interchangeably, yet new research from the Precision Vaccines Program at ... Read More
Shooting for the moon: From diagnosis to custom drug, in one year
One weekend in January 2017, Timothy Yu, MD, PhD, was relaxing at home when his wife said, “Hey Tim, will you look at this post on Facebook? This might be something you’d be interested in.” Doctors had just diagnosed a young girl named Mila in Colorado with Batten disease, a rare and fatal neurodegenerative disorder. ... Read More
Opioid alternative? Taming tetrodotoxin for precise painkilling
Opioids remain a mainstay of treatment for chronic and surgical pain, despite their side effects and risk for addiction and overdose. While conventional local anesthetics block pain very effectively, they wear off quickly and can affect the heart and brain. Now, a study in rats offers up a possible alternative, involving an otherwise lethal pufferfish ... Read More
Science Seen: New microscope reveals biological life as you’ve never seen it before
Astronomers developed a “guide star” adaptive optics technique to obtain the most crystal-clear and precise telescopic images of distant galaxies, stars and planets. Now a team of scientists, led by Nobel laureate Eric Betzig, PhD, are borrowing the very same trick. They’ve combined it with lattice light-sheet to create a new microscope that’s able to capture real-time, incredibly ... Read More
