Physiology & Medicine / Re: What are the harmful effects of Vaping?

« on: 15/10/2021 02:32:06 »

Some madness going on here. There are no vegetable oils in vaping (except in the canabis ones which killed people). Vaping oil would lead to lipid pneumonia among other things.

COVID-19 / Re: Are COVID-19 Vaccines safe for pregnant women (& their babies)?

« on: 30/04/2021 11:47:37 »

Have there been any studies on any differences between naturally occurring antibodies from infection and the antibodies generated by the mRNA shot?

 

Very important question and diserves an answer. I haven't come across a definitive study. Assays to count anyibody levels seem to be an art as much as science, different assays give different results and the same assay in a different lab can give a different answer. And the study would need to be done for at least a six month period. A more severe illness correlates with higher antibody levels so that's a confounder. There will also be people who  have been infected and then vaccinated but don't know they were infected. And of course there are so many vaccines. So nobody knows.

Sinovac's coronavac looks like it's about on par with other vaccines. Perhaps not quite as good but given a bad press

COVID-19 / Re: Would an extended dosage interval work for the Oxford vaccine?

A longer interval between first vaccination and booster virtually always gives a better immune response.

COVID-19 / Should we be treating patients earlier?

« on: 02/11/2020 15:28:23 »

By the time patients are hospitalised the viral load is usually declining and fairly low. The time for antivirals is during the period when the virus is muliplying. The water is muddied by "prophylactic" being applied to both pre-infection and post infection but presymptom treatment. I don't like the second use because, like a lot of infections, some symptoms are caused, not directly by the infectious agent, but by the body's response to the infection and covid surpresses these.

Thaks for that Edwina. I get a little annoyed by articles callig Jenner the father of immuology  vaccination, when doctors had been immunising against smallpox for centuaries in China, India and Africa.

COVID-19 / Re: Resurgence Of Covid-19 in Winter....WHY ? What Does 'Winter' have To Do With It

« on: 29/07/2020 16:10:18 »

No need to shout.

In winter windows are closed and there are more people indoors. There are more seasonal colds about. Most people will have insufficient vitamin D levels.

COVID-19 / Re: Why doesn't the UK just repurpose South Korea's COVID-19 app?

This is truly shutting the stable door after the horse has bolted. Early and rigerous seems to have worked in Vietnam. There, they did three level testing for every case, contacts, contacts of contacts and contacts of contacts of contacts. Hanoi carried out 275,000 tests from 114 cases. Seems more sensible than lets enter into the spirit of the pandemic and see how many people we can kill before a vaccine is available.

COVID-19 / Re: Was the Covid-19 coronavirus created in a lab?

« on: 14/05/2020 18:12:40 »

The patern seems to be that when something suspicious is pointed out, then the researchers will "find" a corona virus that has a feature which will allay the suspicion. I haven't come to the conclusion that the virus was created in a lab but I think we are past the point where it should be labeled as a conspiracy theory.

14% in a study of about 200 pregnant women in New York... if they regularly attend hospital that could might make the figure unrepresentedly high.

I'd be interested to know what risk is associated with atrial fibrillation, but I don't think that level of detail is available yet. Doctors are at pains to point out that AF is a heart condition, not heart disease, but the media use the two terms interchangeably (although I've never seen a written definition of the difference).

For the purposes of the OP's question we can say clocks measure rates of change. A quartz crystal on earth would appear to vibrate more slowly if an astronaut could observe it from the space station. And the astronaut would see a quartz clock on earth running slower than a quartz clock on the space station.
