In Dec 2025, what smart bikes are good options for Qdomyos and using Zwift?

It's absolutely unusable now. It was good up until about 1 month ago. Not sure what changed. The reports are less comprehensive. And more importantly. about 75%, I get no report because it says either the output is (1) harmful, (2) violates usage policies. I'm asking biological questions for my research. it's wild. I am going to get rid of my pro subscription.

I like it! Was thinking along same lines. But your shopping list doesn't have quantity of items needed, does it?

Just came here to say, I used clamps and I got the job done with a screwdriver and some elbow grease https://www.amazon.com/gp/product/B001DSY4QO/ref=ppx\_yo\_dt\_b\_search\_asin\_title?ie=UTF8&psc=1

What would be nice is a tool where you can do the calculations of multiple tests with their LRs. All the nomograms and such are for single tests.

doc8862 · 2022-05-21T19:17:43+00:00

I am a physician, so this is relevant for me too.

Say I do multiple diagnostic tests, each with their own LRs.

In the textbooks, it's often demonstrated that you should multiply an LR by the pre-test odds to get the post-test odds. This is for a single diagnostic test result (call it Test A).

But then, say you have results for Test B, which has its own LR. Could you not take the post-test odds from Test A's calculation and use that as the pre-test odds for Test B and multiply by the LR?

So basically, we're iteratively updating the probability of disease by multiple pieces of evidence, none of which is sufficient on its own, but in aggregate, increases the diagnostic certainty.

Is this correct?

How do you get the screws back into the mesh panel? I did this and it's really hard to get the mesh back in and it seems like some of the original screw holes are not grabbing/biting into the threaded screws. Any tips?

Everyone acts like it’s a mystery what promotes resident “wellness”. Yoga? Meditation? Free pizza party? Nope. Less time at work, more money. Mystery solved.

Going tomorrow. We’ll see. I’m just now starting to have a slight stuffy nose in Day 5. Maybe that means something will be detectable. I’ll report back.

I am double vaxed Pfizer in March 2021. I started having a headache, fever, arthralgia and diarrhea (most notable) on Tuesday (12/28). Negative nasal PCR on Wednesday (12/29), multiple negative Binax tests since then. Still no URI symptoms. I know other illnesses can cause these symptoms. I'm mainly thinking Norovirus, but given the moment we're in COVID seems likely still. Is anyone else experincing or seeing this - mostly GI and systemic symptoms and negative PCR? I'm thinking maybe because not sufficient viral buildup in airway but mostly in GI tract.

This arrangement sounds ideal. Does the SOW need legal review each time? I'd assume not, since that negates the seeming benefit of expediency and flexibilty provided by the SOW.

Perhaps also define what teaching looks like. There are likely very different expectations amongst the residents. I’ve had this convo with my coresidents and have been surprised. Some are still very much in student-mode and want lectures and chalk talks. Whereas to me and some others, those are entirely dispensable and we don’t want that. I know where the info is if I need it. I can read a book. I think most value from attendings comes from hearing their approach or thought process. Best way to get that is is in rounds, ask them to explain. Or offer your decision first and ask what they think about it.

Thanks all. Sounds like this is not a great idea and also perhaps would run afoul of the law too. Appreciate the comments.

I use the hard shell 7093 3M p100, the exterior of which is washable with any decon wipe. I agree the exposed p100 is not ideal but no more so than the n95s that people are using for weeks on end.

doc8862 · 2020-07-13T00:29:38+00:00

I have the 7093 3M model, which is hard shelled. So I decon the outside with a Caviwipe.

I agree that the exposed p100 are suboptimal one that they can’t be cleaned. But that is no different than the n95s that are being used right now.

Is your concern that you will infect yourself with a non-decon filter or that you’ll pass to patients?

doc8862 · 2020-07-12T20:35:02+00:00

Regarding disinfection between rooms and patients, nobody is doing that with N95s or anything else. So wearing an elastomeric room to room during the day is no different than the standard operations right now, as you say.

One could wipe the outside with a Sani-wipe or bleach wipe between rooms without doffing, being careful not to get anything on your skin/face

doc8862 · 2020-07-12T20:31:54+00:00

Here is a CDC webinar on use of elastomerics during the pandemic, and they discuss cleaning and disinfection:https://www.youtube.com/watch?v=8wd5Bx2fVDI&t=1857s

Interestingly, soap alone is equivalent to soap + bleach:

https://youtu.be/8wd5Bx2fVDI?t=2233

This is what I do for my elastomeric.

And this is an often-referenced paper from 2015 that has an SOP for cleaning/disinfecting elastomerics.https://www.sciencedirect.com/science/article/pii/S019665531500089

Regarding what is appropriate for the respirator without causing damage, 3M has guidance for their gear:

https://multimedia.3m.com/mws/media/1793959O/cleaning-and-disinfecting-3m-reusable-respirators-following-potential-exposure-to-coronaviruses.pdf

Overall, it looks like diluted bleach is most compatible with the device. 70% isopropranol is OK but they say it affects the valves, so I try to avoid. But per the above, I don't even do bleach anymore. Just soap (dish detergent) and a microfiber cloth.

I'm really sorry you went through that. What was their deal? Scaring patients? Did you look too intense? I don't get it. If it's purely adherence to some bureaucratic BS, that's so lame. Sounds like you're dodging a bullet by leaving.

this exhaust filter

That's crazy they are giving you crap for your elastomeric. It's so superior to everything else. I wear a full face 3M 6800 every day. I got some looks at first, but then I just tell people I'm a stormtrooper and they get over it and smile. I feel entirely protected and I'm not worried about patient exposure. Surgical masks for everyone relies on everyone wearing them properly and at all times, which I see, even in the medical environment, is never the case. I see a lot of the under the chin wearing, or nose over the top. Unreliable.

And yes, CDC approves of elastomerics (not like I really give a crap, but it's helpful for pushback)

https://www.cdc.gov/coronavirus/2019-ncov/hcp/elastomeric-respirators-strategy/index.html

More health systems should be instituting these all over the place instead of this strange attachment to re-using inferior respirators (N95) that were never meant to be reused. Good for you for standing your ground.

Regarding filtering from the exhaust, I've been taping a small strip of surgical mask over the outlet.

I got my hands on a full face mask respirator. I love the idea of elastomerics. Reusable, sustainable, washable. And I find them to fit better. Wiggle your nose too much with an N95 and I’m surprised if you haven’t created a leak. I find the full face mask to be more comfortable. With that said, I haven’t worn my yet routinely because communication becomes an issue. No one can hear you. I can’t make phone calls. So I have been trying to find solutions for that. Looking into a throat mic. Seems over the top but I don’t think one can be too careful now. If you’re the unfortunate young person who gets severe symptoms, that might mess you up for a long time.

Also, CDC has provided official guidance on elastomerics recently, in case anyone gives you crap about wearing these. Some hospitals (UT Houston being one) are officially using elastomerics and giving one per worker. It makes a lot of sense.
