One of my brothers managed to convince Kaiser to fix his deviated septum and now he sleeps better but yeah, a lot more people come to doctors with sleep apnea even after surgery and most kind of look down on it as a treatment for sleep apnea.

Reply to An umbrella review of randomized control trials on the effects of physical exercise on cognition has concluded that there is no solid evidence showing a causal relationship between exercise and positive effects on cognition. by clib

I'm a cognitive neuroscientist. I'm not a specific expert on cognitive rehabilitation or training, though I've flirted with similar type of work. I work mainly in psychiatry.

Some of the things we have tried to do include brain stimulation to modulate cognition. Also I've at least read in the past about cognitive rehabilitation programs for different disorders. And I go to conferences where occasionally see posters on cognitive training and generalization

There is probably very little in the human brain that is as difficult to reliably affect as adult cognition. Our cognitive abilities are fairly set it seems by the time we are in our 20s. They can go down, and we can do things that maintain them. But it is very hard to increase those abilities. There may be certain transitory things, like going from a condition of sleeping very poorly to improving your sleep, which will have notable outcomes. But that's more the removal of something detrimental then adding something beneficial.

So I'm not surprised that the net result of a review paper is pretty much a null. Because the majority of things we have attempted to improve human cognition have not been very successful. Sometimes we can substantially train summon up on a few specific tasks, but then we find that extraordinary skill in one cognitive task doesn't generalize to non-trained tasks.

One of the downsides of a review, and I'll admit I didn't actually be the paper, is that they tend to jumble together several factors, and miss some of the nuance that can be happening. So it may be that some very specific cognitive abilities are somewhat enhanced either short-term or longer term by an increase in physical fitness. But a lot of studies that get done tend to be short, quick, and easy, or look at very broad strokes abilities. So maybe with further work we will identify some specific benefits, particularly in the cases of either very intense or longer term lifestyle type major changes.

And, none of this means exercise doesn't have other mental benefits. There's some decent evidence, at least last time I checked, of an antidepressant effect to physical activity. I had a colleague go off sick leave following chemotherapy treatment, because after everything was said and done they were exhausted and depressed. One of the things we talked about is the potential benefits if she can get back into running, because there is a mood boosting effect at least potentially.

So, information, cognition is very difficult to modify in adults. But there may be other mental benefits to physical activity as well. Get me have different benefits and different clinical populations.

This is not a form of specifically physical exercise that's going to be tested in a clinical trial. That's more whole experience that includes both physical, mental, and other potential benefits such as being able to nature. So I wouldn't call that approach based on physical activity

I'm not saying it wouldn't be beneficial. I'm saying it's out of scope for this kind of review. Typically the things reviewed include cardiovascular exercise programs on a gym, treadmill, or bike, or other sorts of activities like that. Things that can be done in the clinical setting.

Reply to The risk of developing osteoarthritis, a common, incurable form of the condition, was 58% higher among those with eczema or asthma compared to the general population. Those with both asthma and eczema were twice as likely to develop osteoarthritis compared to the general population. N = 100,000+ by MistWeaver80

I'm not a person in the medical field, so I have no clue how close or far off this question may be. Could it be lack of oxygen and water causing osteoarthritis? Since people with asthma will have a harder time getting oxygen and others with eczema might not hydrate enough.

Reply to Research found weight loss was associated with decreased risk factors for cardiovascular disease and Type 2 diabetes for at least five years — even if some weight was regained, according to a review of research on behavioral weight loss programs by Wagamaga

call me fatphobic all you want but you should strive to be at a healthy weight. If you have some medical condition thats one thing but to allow yourself to get that big otherwise isnt okay and we shouldnt be suprised that losing that excess is good for us.

Did you have any abdominal pain after wearing the CPAP? I’d wake up, ripping the mask off my face and have abdominal pain similar to how food poisoning feels. Just a constant pain that wasn’t sharp, but hurt pretty bad.

That’s exactly what the sleep physicians said to me after I came back after my jaw surgery didn’t work. “I could have told you that wouldn’t work. Why don’t you try a different sleep apnea device for central sleep apnea?” Ya that didn’t work for me just like the other CPAP because my esophageal sphincter kept opening due to the pressure from the air causing severe abdominal pain. Now I play a didgeridoo every night and it does seem to help a bit but its not a perfect solution. I might go to an ear nose and throat doctor to see if nasal inflammation is the culprit.

Reply to comment by marketrent in Aggregate measure of financial misreporting for nearly 2,000 companies in the U.S. suggests that the collective probability of fraud across major companies is the highest in over 40 years by marketrent

the receivables thing is pretty old. back in the 90's a bunch of companies were selling a lot of stuff to the dot coms and other startups on credit and lost big when they went under and then when all that gear was resold on ebay and chapter 7 auctions

I’m curious because I also have OSA, what did you mean by “low airflow in some areas?” I think I also might have chronic sinus inflammation.

I had jaw surgery to fix my sleep apnea a couple years ago and it didn’t help me. So in my case there may be something else at play. There are other surgeries that may help in your case. Also CPAP is great if it works for you. Unfortunately it caused me a lot of issues, which is why I tried the surgery. If you want any advice feel free to send me a message. I have a routine right now that has definitely helped but it’s not perfect.

Unfortunately I had jaw surgery to fix my sleep apnea and it didn’t really seem to help much. It’s not a cure-all and it does carry some very serious side effects that I’m worried about. It’s a last resort option. I only decided to take the risk since I couldn’t use CPAP because I would wake up with severe abdominal pain from air filling my stomach. I guess this was caused by a faulty esophageal sphincter that would open when using the CPAP.
