Roadside drug tests are unreliable, so why are they so widely used in the U.S.? Meanwhile, researchers who make "health disparities" the focus of their work sometimes misrepresent their results. Here's a textbook example from a study that used pulse oximetry to measure disparities in COVID-19 treatment.

At the beginning of the year, the CDC and FDA noted “a preliminary safety signal for ischemic stroke among persons aged ≥65 years” who had received the COVID bi-valent vaccine, as well as a similar but "higher" signal in individuals receiving the influenza vaccine at the same time. Now, a study has confirmed that safety signal.

It seems like a bit of common sense: the higher the viral load – in this case of COVID – the greater chance you have to transmit the disease to another. As it turns out, one of the ways we may characterize “infectivity” is when viral load peaks. Omicron infections peak later, and that has clinical implications.

A recent, bizarre murder case in Minnesota involved a physician (a poison expert) accused of poisoning his wife with a toxic gout drug called colchicine. The fact that she didn’t have gout, and that he had taken out a $500,000 life insurance policy, won’t help Dr. Connor Bowman‘s defense much. And a little lesson on the risks of using toxic drugs therapeutically.

Tracking our health is all the rage. Advancements in technology have catapulted our understanding of how our bodies work and continue to provide new opportunities for healthcare. But while constant monitoring of our physical health sounds great, there may be drawbacks to our mental health and how we relate to our bodies and other people.

Cato Institute's Dr. Jeffrey Singer, in an opinion piece in USA Today, writes that for years we've been buying and using an ineffective, potentially dangerous decongestant. Why? Just another futile attempt to restrict access to illegal drugs, in this case, methamphetamine. With phenylephrine off pharmacy shelves, the ACSH advisor explores what this means.

As we age, bones creak, hearing wanes, and cognition diminishes. Promises of rejuvenation have always besieged a vulnerable market seeking the fountain of youth. Now, there seems to be a clinically tested elixir that promises to restore lost brain power – a simple Chinese herbal remedy. So, does it work?

Regulators are supposed to abide by the “bargain” that society has made with them: Civil servants are granted lifetime tenure and are protected from political pressure and retaliation, in return for which they are supposed to make decisions based solely on the public interest. But, often, they do not. 

Over the last decade, the Centers for Medicare and Medicaid Services (CMS) launched several initiatives tied to incentives to “providers” to improve care. A peer-reviewed study spins out to interested clinicians the clinical benefits and financial costs of an initiative to reduce cardiovascular disease. The full report to CMS spells out the failures.
