    You'll find no interest in this by Trumpers because Trump doesn't endorse it

    Yep! But I am building a repository of research basically to silence those who are claiming that thier blog posts are more valid than systematic review of literature

    Don’t want to drink fish tank cleaner? Don’t like the green apple horse dewormer? Or just want something effective that you don’t have to wait for your favorite politician to endorse? Want to make sure the promised vaccine will work well for your? This may be for you!

    Exercise!

    As an introduction:
    https://www.google.com/amp/s/www.irishtimes.com/life-and-style/health-family/fitness/does-exercise-help-or-hinder-the-body-s-ability-to-fight-off-infections-1.4198614?mode=amp

    Of course everyone has heard exercise is good for your overall health, but what about prevention and survival rates of viral infections? How about better immunity from vaccination? The above article points out what we’ve believed for years. That regular exercise does help the immune system fight off infection. It also alludes to the suspicion the immune system was suppressed immediately following more strenuous exercise. Turns out it’s the opposite. Exercise increases immune response in the lungs for instance after exercising. Here is a review of numerous studies leading to that conclusion. It also presents the evidence for increased immune response to vaccination in active individuals. Of course the linked review can be used to access the underlying research if one is interested in any of it.
    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5911985/
    Best of all, most benefits from exercise are available to everyone. Young or old, thin or not so thin. All you have to do is exercise!

    Of particular interest to me was the effect of exercise after infection occurs. Chris Cuomo madd some comments in a video I say that made me interested to learn more about this. He kept saying don’t lay down and die. Be active. Fight the virus. I can’t find the video right off, maybe someone can supply it if they have it. It was really good in my opinion.

    Anyway here’s a sample of research in this area.

    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2812897/

    https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0002108

    https://www.eurekalert.org/pub_releases/2020-04/uovh-cem041520.php
    Obviously we don’t know much about exercise and C19 specifically, but that’s the case for everything at this point.

    If nothing else, regular exercise will help with any underlying conditions you have or may develop such as obesity, heart disease, etc. that increase mortality rates astronomically with C19.

    More importantly that it is not misinterpreted by twonks on the Internet spreading misleading and dangerous information (Alex Jones et al)

    There will always be opposite opinions, some are respectable and some are not. Just let the truth prevail.

    Yes I agree

    Meanwhile we have people confusing anecdotal evidence with scientific research and that is frustrating

    I really like this description.

    This concept presents itself with a impressive conformity of non-uniformity!

    Brazil halted a hydroxychloroquine test due to heart damage according to an article in MedRxiv.

    Patients not getting the pacebo were given that drug plus azithromycin - which is often used in conjunction with hydroxychloroquine in the USA, too.

    The test was halted due to fatal heart arrhythmia showing up. Both those drugs are known to have heart risks.

    Here is some good news on the treatment success from the drug Remdesivir

    Dow futures rally more than 800 points after Gilead coronavirus drug reportedly shows effectiveness

    Ran across this today.

    Looks like a promising vaccine. Of particular interest to me was the micro needle array delivery system. No carriers, preservatives, or adjuvant. A patch with 100 microneedles made of cellulose deliver they vaccine to the skin. Very good and fast immune response as well as being a cheap delivery system that can be mass produced quickly. Also, the patch containing the dried vaccine can be irradiated to sterilize it to prevent contamination or infection of the recipient with an opportunistic pathogen.

    Read this shortly after it was posted and was struck by the section on development of resistance to remdesivir. Specifically how in past experimentation resistant viruses became less pathogenic and less robust even when they did infect.

    If this holds true for all similar viruses to the ones already known to have some response to remdesivir, it would be theoretically possible to artificially force populations of viral groups into being less pathogenic but more importantly less damaging even if infections occur. If we figure out the exact mechanism and could alter robustness without affecting ability to infect, it could be even better. It would take time and effort but could result in something similar to screwworm eradication. For those not familiar here’s a link.
    https://www.aphis.usda.gov/aphis/ou..._release_programs/screwworm/screwworm_history

    Of course an approach in virus would look very different because screwworm involves sexual reproduction, I’m just using screwworm as an example where coordinated efforts to alter populations can work.

    The wrench in the works of using remdesivir as described above would be the early reporting of 25% or more severe side effects including liver and kidney damage. The reporting on the latest trials (that we don’t have access to yet apparently) doesn’t mention side effects so that may or may not be accurate.

    Anyway, this is a fascinating drug whether it’s the final answer to C19 or not.
