When Hype Meets Medicine: the Curious Case of Dexamethasone in COVID-19

Evidence-based medicine requires evidence. It’s not optional.”—these golden words in science- and evidence-based medicine were re-emphasized by Dr. Angie Rasmussen, virologist at Columnbia University and prolific science communicator, on Twitter recently.

For proper appreciation of the magnitude of this quote, let me elaborate on the fascinating context in which Rasmussen wrote it.

Failure as a Necessary Step in Drug Development (Tip of My Hat to David Kroll)

The Forbes magazine has an impressive line-up of columnists; I follow many of those who write on the sciences and healthcare-related topics. One of them is Dr. David Kroll, a pharmacologist by profession and passionate, long-time science communicator. His column yesterday had especial interest for me; in it, David took the example of Dr. Derek Lowe—a pharmaceutical industry scientist who’s also a prolific and erudite blogger—who was apparently his inspiration for starting his own blog, and mentioned an intriguing thing Dr. Lowe had said during a Question and Answer session with Karen Weintraub for STAT News (quoting from David’s column including original links, below):

2015 Nobel to Traditional Chinese Medicine Expert is a Win for Evidence-based Pharmacognosy

Yesterday, on October 5, 2015, one half of the Nobel Prize in Physiology or Medicine was awarded to scientist and pharmaceutical chemist Tu Youyou (alternatively, Tu Yo Yo, 屠呦呦 in Chinese), for her discovery of the anti-malarial Artemisinin. (The other half went jointly to William C. Campbell and Satoshi Ōmura, for their discovery of a novel therapy for roundworm infection.)

Tuberculosis, the global scourge, and a new drug-design strategy

Every year on March 24, World Tuberculosis (TB) Day is observed to commemorate the discovery of the etiological agent of this disease, the bacterium Mycobacterium tuberculosis by noted German physician and microbiologist and Nobel Laureate, Robert Koch (1843-1910). The infection occurs via inhalation of the air-borne bug; therefore, the disease primarily affects the lungs, but it can spread to other parts of body as well, such as the central nervous system (brain and spinal chord), bone, and internal organs. If adequate treatment is not instituted (and sometimes despite therapy), a person with active TB disease will likely die. In the United States, in 2010 (the latest year for which statistics are currently available), of the nearly nine hundred deaths in which TB was suspected, TB was confirmed in roughly 4 out of 10 cases, and a total of 569 people died from TB. Globally, in 2012, an estimated 8.6 million people contracted TB, of which 1.3 million died.

PLOS One paper on Anthelmintic Efficacy of Gold Nanoparticles: My Questions to Authors

Every so often, some paper happens to grab my attention for various reasons. As I read the paper, often I have questions. Not all of those questions, unfortunately, can be easily submitted for answers. In recent times, one such paper was published earlier this month in PLOS One. The great benefit of the Open-Access model of PLOS is that it allows a reader to ask questions directly of the authors. This level of engagement is very laudable, especially to someone like me who has an interest in the communication of scientific facts.

Exciting Science: Oncolytic Viruses (Review published in PLOS Pathogens)

Science is awesome. But I expect you already knew that, dear readers o’mine. In science laboratories across the world, every day dedicated researchers are testing ideas, generating and evaluating hypotheses, critically analyzing observations, and thereby, making significant contribution to the humanity’s attempts to understand in greater depth and detail the wonderful natural world that surrounds us, of which we, along with other living beings and non-living objects, form a part.
