Reply to comment by W3remaid in Vitamin D supplements linked to reduced risk of suicide, study of veterans finds by thebelsnickle1991
If suicidal thoughts are considered a health-status, then this whole study is pointless, because they're controlling for the thing which directly leads to suicide. Perhaps I'm misunderstanding your point?

Soooo I think I’m the only on that thought “sunscreen,” when I saw “screen time,” and then got worried for myself, since I was a kid that played outside and on the beach a lot. Then coming to the comments, I realized my error. Don’t worry folks, I’m not procreating haha

They are sending a few missions to Venus. One of them even utilizes a balloon to stay in the upper atmosphere for an extended period. I would rather see crewed missions to Venus then Mars. Mars has dozens of ways to kill you while the environment in the clouds of Venus is comparatively simple. The only thing that would give me real pause is if we discovered life on Venus.

That doesn’t really work because this is a case-control design, meaning that their health status is controlled for. If they were were sick to the point of being non-compliant with meds that would be reflected in their control match

One other commenters gave a really good one, people who fill out subscriptions are less likely to have committed suicide because they still care about staying alive enough to take care of themselves. Suicide is a damn complicated subject, but if one is considering it, making the effort of filling a prescription seems... pointless, and I think if we look at people who fill out any non-psychoactive drug vs. committing suicide, we'd see a similar correlation. (Psychoactive excluded because things like depression meds are specifically meant to reduce suicide risk factors, and I believe would confound any results)

That's what I've been saying since the Space Shuttle was developed.

Yeah but what if I don't want to live a long life?

That’s interesting, since the case and controls were matched to account for confounders (health status, socioeconomic factors, etc) —what do you think the alternative explanation might be?

I believe it. Before being diagnosed I had a hard time in the winter. Leave when it's dark, come home in the dark. Pretty sure it was a minor case of depression and I believe my dad went his entire life with it undiagnosed. While I try to be very good about taking daily supplements there's been a couple times where I didn't for a while. That low key depression comes back when there's no reason for it.

We're supposed to trust a paper that uses the default Stata graph format?

Unfortunately no, this is an observational study, not an experiment, so even strong correlations are just correlations.

Read the whole paper, could not figure out what ‘wearable sensors’ they used to measure sound levels? Maybe I missed it?

My mother says talking vitamin D is like a vitamin version of an antidepressant.
I also feel a difference in my mood, especially in the winter when the sunlight is minimal.
I know it's not scientific, but my own observations make me think those with low vitamin D might experience depressive symptoms. And many people do not go outside enough to get enough vitamin D.

Reply to comment by JerrodDRagon in New evidence suggests that ‘hybrid’ immunity, the result of both vaccination and a bout of COVID-19, can provide partial protection against reinfection for at least eight months. Immunity acquired by booster vaccination alone seems to fade somewhat faster. by MistWeaver80
If people were getting vaccinated as soon as they could, in the US, for many people the circulating variants were different by the time you needed to get your fourth booster. It became more clear that we needed a bivalent booster, but it wasn't quite out yet.
My guess is that it wasn't that it wasn't effective, just less effective than an updated one would be.
Eating well and exercising protects your heart. COVID causes a lot of clotting. It might just be that people with healthy hearts are better able to handle the stress on the body than people whose hearts are already stressed.

Parents with executive disfunction might be influencing these results both genetically, and behaviorally. ADHD parents can have a hard time staying engaged.
So the study mentions, this doesn't prove a direct cause relationship, they need a better designed experiment for that.

Are you sure? Babies tend to look around at random, at people, or at the ceiling if laying down. This sounds like it is referring to parents deliberately making their baby consume television

There hasn't been a ton of recent testing of the smallpox vaccine. We don't have smallpox challenge trials for example.
Smallpox immunity wanes after vaccination, but still can prevent infection and severe infection.
https://www.health.ny.gov/publications/7022/
Part of what makes the smallpox vaccine effective, is that smallpox is not circulating in the population and mutating. Smallpox is also a DNA virus, and DNA viruses tend to have fewer mutations, so vaccines continue to work for them, rather than the flu which is RNA and mutates like crazy. It's probably most effective to think about the antigen that the vaccine is training your body to target, and the delivery mechanism for that.
mRNA vaccines are really going to change the vaccine landscape.

Agreed! I don't think all children shows need to be "educational". But, the bonding and interactive aspect seems significant.
