FDA regulators are mad because Moderna did not release all of their study information to the vaccine advisory board, which, upon closer study, shows that 1.9% of people who received Moderna's original vaccination subsequently caught Covid, while the bivalent vaccine - which should have offered increased protection against the Omicron variants - had an infection of 3.2%!

Moderna received $5 billion from the US government to develop this vaccine and then didn't disclose all of the study information, apparently in an effort to get it approved and make more profits.

From the CNN article: "The six FDA and CDC advisers interviewed by CNN said that this infection data wouldn’t have changed how they voted, because the data had such limitations, but it still should have been presented to them."

New England Journal of Medicine summary of the studies:
https://www.nejm.org/doi/full/10.1056/NEJMc2213907

The NEJM article at least has a disclaimer: "Limitations of our study include the small sample size and follow-up period of our groups. We also note that the between-group comparisons were not controlled for factors such as age, vaccine type, and health status, which may have had an effect on antibody responses. These findings may be indicative of immunologic imprinting, although follow-up studies are needed to determine whether antibody responses will deviate over time, including after the administration of a second bivalent booster."

This is pure awesome! I'm personally interested as I have a condition called epiretinal membrane that, if it gets seriously worse, will mean that I will no longer be able to see straight lines. Don't tell me that won't screw me up as a photographer! And I have no idea how that will affect my ability to read, and photography, reading, and watching movies are some of my major joys in life.

ANYWAY, this article from the BBC talks about a new gene therapy that just began human trials that, if successful, will STOP age-related macular degeneration (AMD). AMD is a genetic condition that will ultimately result in blindness, this treatment involves injecting a virus into the back of the eye which (I guess) re-writes the bad gene and prevents it from doing its dirty deed. They're testing it on people already suffering from AMD, I guess so they can quantitatively see that it works by seeing that their vision doesn't get worse.

The article goes on to talk about two other causes of blindness that can be treated: something called choroideremia, a genetic problem which affects young men and eventually causes total blindness. They now have a genetic treatment for it. And a stem cell treatment for people where they can directly implant patches of stem cells in the eye and have restored vision in two people.

In my case, there is a treatment for epiretinal membrane, but it is extremely high risk: they literally scrape the unwanted membrane off the retina. Obviously the risk of physically damaging the retina is considerable, so it's not a recommended procedure, and I'm not remotely near that level. I'm about as early in the disease's progression as possible: they've detected it, I'm being monitored, and I'm not seeing any distortion of straight lines right now, so it'll be some time (we hope!) before it becomes a problem.

As if I don't have enough medical shit in my life to deal with! :-)

The man was born without a left hand and had a prosthetic that sensed muscle movements in his forearm stump and moved fingers accordingly. He's been using one made by a 3-D printer that cost $50 to make, and after a year, prefers it over the one that was over 800 times more expensive.

This could be a real boon to orgs like Doctors Without Borders in places like Sudan.

And could lead to a number of illnesses. The basic issue is that as your eyes age, they filter more blue light, and they've linked this lack of blue light to various problems. Solution? Replacing the lens surgically with one that doesn't filter blue.

There were some very interesting Slashdot comments on people who had their lenses replaced and others who had circadian problems.

Pretty cool. Low doses were shown, in mice, to reduce levels of inflammation associated with Alzheimers. They are cautioning that you can't extrapolate it to human scale right now, further "...cautioned that any benefits wouldn't be experienced by people whose brains have already started to deteriorate, nor those whose brains are still forming. But for adults looking to prevent dementia, marijuana could play a role — albeit at very small doses, well below the level of psychoactivity.

"It will take the recreational use out of it," said Marchalant, who made a rough extrapolation from rat doses to a single human puff of pot."
