Stop pushing statins? + Transplanted pig heart had virus + Candy coated med pills

Virus found in pig heart used in human transplant

INTRO: Researchers trying to learn what killed the first person to receive a heart transplant from a pig have discovered the organ harbored an animal virus but cannot yet say if it played any role in the man’s death.

A Maryland man, 57-year-old David Bennett Sr., died in March, two months after the groundbreaking experimental transplant. University of Maryland doctors said Thursday they found an unwelcome surprise — viral DNA inside the pig heart. They did not find signs that this bug, called porcine cytomegalovirus, was causing an active infection.

But a major worry about animal-to-human transplants is the risk that it could introduce new kinds of infections to people. Because some viruses are “latent,” meaning they lurk without causing disease, “it could be a hitchhiker,” Dr. Bartley Griffith, the surgeon who performed Bennett’s transplant, told The Associated Press.

Still, development is under way of more sophisticated tests to “make sure that we don’t miss these kinds of viruses,” added Dr. Muhammad Mohiuddin, scientific director of the university’s xenotransplant program... (MORE - details)


Should we stop pushing statins?

INTRO: I freely admit this to my patients: I am a statin agnostic. It’s rather embarrassing. Statins have been around almost as long as Religion, undeniably lowering cholesterol levels the whole time, and yet I cannot quite make up my mind about them, despite all the studies and sales.

A recent meta-analysis published in JAMA Internal Medicine led by Dr Paula Byrne re-stated the primary causes of my agnosticism: people with a low risk of a heart event are not very likely to benefit from a statin drug.

True, it is almost universally accepted that people who have already suffered a heart attack or have other known cardiovascular disease substantially reduce their risk of another bad event with statin usage (so-called “secondary prevention”). But still controversial is what to do with the 25% or so of U.S. adults over 40 who don’t have a history of known heart disease but are currently recommended to take a statin (in the name of “primary prevention”).

In a nutshell: should healthy people with high cholesterol be put on statins? The question is informative, both for patients and their doctors, as the basics of this quandary are statistical, but the complexity lies in our physiology.

First, though, the study. Not coming to us through the pharmaceutical industry, but rather multiple research centers, we might have reason to trust the authors’ intentions... (MORE - details)


Candy-coated pills could prevent pharmaceutical fraud
https://news.ucr.edu/articles/2022/05/06...ical-fraud

RELEASE: While most of us were baking sourdough bread and watching "Tiger King" to stay sane during the pandemic shutdown, UC Riverside bioengineering professor William Grover kept busy counting the colorful candy sprinkles perched on top of chocolate drops. In the process, he discovered a simple way to prevent pharmaceutical fraud.

The technique, which he calls CandyCode and uses tiny multicolored candy nonpareils or "hundreds and thousands" as a uniquely identifiable coating for pharmaceutical capsules and pills, is published in Scientific Reports.

Counterfeit or substandard medicines harm millions of people and cost an estimated $200 billion annually. In the developing world, the World Health Organization estimates that one in 10 medical products is fake.

Grover's lab has previously worked on simple, low-cost ways to ensure the authenticity of pharmaceuticals. Other researchers have been interested in putting unique codes on pills that can be used to verify their authenticity, but all of those schemes have practical limitations.

"The inspiration for this came from the little colorful chocolate candies. Each candy has an average of 92 nonpareils attached randomly, and the nonpareils have eight different colors. I started wondering how many different patterns of colored nonpareils were possible on these candies," said Grover. "It turns out that the odds of a randomly generated candy pattern ever repeating itself are basically zero, so each of these candies is unique and will never be duplicated by chance."

This gave Grover the idea that the nonpareils could be applied as a coating to each pill, giving it a unique pattern that could be stored by the manufacturer in a database. Consumers could upload a smartphone photograph of a pill and if its CandyCode matches one in the database, the consumer could be confident that the pill is genuine. If not, it is potentially fraudulent.

To test this idea, Grover used edible cake decorating glue to coat Tylenol capsules with nonpareils and developed an algorithm that converts a photo of a CandyCoded pill into a set of text strings suitable for storing in a computer database and querying by consumers. He used this algorithm to analyze a set of CandyCode photos and found they function as universally unique identifiers, even after subjecting the CandyCoded pills to physical abuse that simulates the wear-and-tear of shipping.

"Using a computer simulation of even larger CandyCode libraries, I found that a company could produce 10^17 CandyCoded pills -- enough for 41 million pills for each person on earth -- and still be able to uniquely identify each CandyCoded pill," Grover said.

Even more unique CandyCodes could be created with the introduction of more colors or combining different sizes or shapes of candy nonpareils. CandyCodes could also be used to ensure the authenticity of other products that are often counterfeited. Bottle caps, for example, could be coated with adhesive and dipped in nonpareils to ensure the integrity of perfume or wine and garment or handbag hang tags could be coated with glitter.

CandyCoded capsules or tablets have an unexpected benefit for the consumer as well. "Anecdotally, I found that CandyCoded caplets were more pleasant to swallow than plain caplets, confirming Mary Poppins' classic observation about the relationship between sugar and medicine," said Grover.
