As I watch the current debacle of our children preparing to return to school, I more and more feel it is time to take a moment to talk about the errors we have made. My original thoughts turned to responsibility and accountability, words that have occupied my professional life as a surgeon, words molding my thinking just as they molded my character.

If you're someone who believes that the Food and Drug Administration is purely guided by science and that politics has never influenced its decisions, we likely live on different planets. As for some background, here's some recommended reading to go with our overall perspective on this issue.

My PSA was 22 – but my biopsy only showed inflammation. I was needlessly upset, and it seems like I underwent an unnecessary procedure. There has to be a better way!

Navalny, a Russian anti-corruption activist and well-known critic of President Vladimir Putin, is being treated in Germany for an apparent case of poisoning by an "organophosphorus neurotoxin." But which one: the insecticide or the chemical weapon? Here are some clues.

Another clinical trial of remdesivir – this time with hospitalized patients having moderate COVID-19 – yielded disappointing and strange results. The first randomized trial showed a modest benefit in patients with severe COVID, so theoretically the drug should have worked better in patients who weren't as sick. But, it didn't.

There are any number of papers supporting the idea that higher levels of air pollution are inversely correlated with poorer health outcomes. These studies all suffer from the fellow travelers of air pollution, traffic density, poverty, and lesser education which confound a clear linkage between air pollution and health. A new study offers a possibility.

The most recent workshop of the Beyond Science and Decisions series was conducted at the National Institute for Occupational Safety and Health (NIOSH) in Cincinnati, Ohio, in February of this year.

If artificial intelligence can replace some highly specialized medical doctors, is any job safe? It appears the biomedical profession is ripe for an overhaul.

Obesity remains a significant health problem, especially when it increases one's susceptibility to COVID-19. While better eating habits and exercise have long been the mainstays of weight reduction, in the last 10-to-15 years surgical rearrangements of the gastrointestinal tract have come to the fore. Not only do they reduce weight, but they've improved hypertension and diabetes mellitus. A new study compares surgical and medical management for diabetes.

In addition to the multiple rhythms that underlie our individual lives, when we come together we tend to "synch" with one another. Whether it be as simple as adjusting the pace of our walking; the give-and-take of our conversation; or as seemingly sophisticated as the murmuration of starlings, it is a biologic phenomenon. How do we entrain, tie together, our independent rhythms?

Our body hosts many rhythms. While they are downplayed by Western medicine, Eastern medicine utilizes them as tools. A serendipitous observation by researchers links the breathing during mantras with that of prayer.

Hating on “seed oils” is the latest dietary fad. Here’s why it’s misguided.

Large pharmaceutical companies are multinational organizations with incentives to distribute their vaccines broadly.

There are both advantages and disadvantages of studying repurposed drugs to battle COVID-19. In an interview, ACSH advisor Dr. Kathie Seley-Radtke weighs in on this method while providing a glimpse at some of the very promising research now going on in her lab. If you want to know how antiviral drug discovery might tame COVID-19, this is a must-read.
