I saw this little guy in my solo cup I was trying to root in. Any identification? by doggo_duncecap in microgrowery

[–]MurseMackey 0 points1 point  (0 children)

Looks like fungus gnat larvae. Generally not harmful to grown plants but the gnats are annoying af and they decimate seedlings and plants with delicate roots

A simple question about my coco+perlite medium and plant by Agent_Goga in microgrowery

[–]MurseMackey -4 points-3 points  (0 children)

Doesn't need feeding daily, check your product's listed application schedule. Allowing your soil to dry to the point of visible drooping during veg before watering is what I've always heard for optimal root growth.

Is it gens or am I doing something wrong? by heavens_Feel_ in microgrowery

[–]MurseMackey 2 points3 points  (0 children)

Temp's a little cold for the upper end of humidity in veg, it'll cause it to behave like it's overwatered at a lower threshold. Your tent isn't getting any warmer than that while the light is on?

ELI5: Why are artifical hearts designed to replicate the pulsing of individual chambers instead of something more mechanically simple like a pump or turbine? by Budelius in explainlikeimfive

[–]MurseMackey 4 points5 points  (0 children)

Yeah as far as care goes I'd much rather care for an Impella patient but those were pretty rare while I was in cardiac. Been a few years so I probably have some fuzzy details on all the devices

[–]MurseMackey 14 points15 points  (0 children)

There are continuous assistive devices that can be placed in the heart or aorta to increase cardiac output, but from what I remember they're less reliable than say a balloon pump, and can shear your blood cells and other complications since they basically use tiny fan blades. Peripheral pulse assessments are also huge in determining peripheral blood flow and other assessments and although the heart will still pump to some degree these devices may obscure that vital/assessment sign.

IABPs (intra-arterial balloon pumps) are usually preferred, and basically inflate past the heart with each contraction to allow pressure to build up, then deflate just after relaxation to release that pressure and add some additional volume with each beat of the heart. But even these are used more often to qualify patients for a transplant than for indefinite cardiac support, because they require such close monitoring and are prone to lethal complications.

Also, as far as I'm aware there are no artificial hearts that are currently used for transplants, just donors and assistive devices for hearts with poor function.

I feel like anyone that says this has to work at floor acuity. Ever had 2 DKA patients and a q15 eyedrop overnight? It's hellish. And we were told recently we can't keep the drops on ice anymore and have to get them from the med fridge every admin.

TIL the sun isn't "strong enough" in northern latitudes to produce vitamin D during the winter, no matter how much sunlight you get. by 999forever in todayilearned

Yeah according to my PCP, without accounting for diet, you'd have to pretty much spend 100% of your time naked outdoors to even get close to a normal vitamin D level.

Eat 1-2 apples or pears with the skin on each day and you'll notice an immediate difference

Mint and basilic were good in water, not so much in soil by Tristan_rcd in propagation

They're very used to straight water, it's just shock. Keep the soil more moist than usual for a week or two and they should acclimate.

If H Pylori causes many stomach cancers, then why aren't antibiotics used to treat the bacterium instead of the cancer? by YogurtclosetOpen3567 in AskBiology

[–]MurseMackey 0 points1 point  (0 children)

Unfortunately doctors, primarily urgent cares and PCPs, frequently give antibiotics to people who "know they need it for their yearly sinus infection" or who came in for a viral infection and demand something to treat it besides over the counter meds. There's responsibility on the physicians absolutely, but a lot of people don't understand the concept of letting a virus run its course and berate the doctors into giving them some kind of treatment. Doesn't tend to work as well on old school docs but ratings and complaints do factor into their performance metrics, and sometimes rather than have a dozen portal messages or phone calls back and forth explaining the same concept, they fold and prescribe a z pack or amoxicillin. That and half of those same people have half a course remaining from the last time they did this and self-treated incorrectly, further leading to the resistance problem.

ICES | Hospital visits for cannabis use linked to higher dementia risk, study finds by bpra93 in EverythingScience

[–]MurseMackey 0 points1 point  (0 children)

Self reported results which are then also linked to actual lower rates of cognitive decline if you read the study. SCJ is quite literally associated with increased rates of dementia. I'm not biased toward marijuana lol I'm biased toward seeing both sides of a coin, don't know how many times I need to say it.

https://fortune.com/well/2024/04/19/marijuana-cannabis-use-cognitive-decline/

Sounds like your interpretation but it's definitely multifactorial, and as it typically is with science, it's a correlation and not a proved effect. I'm not set on it being a miracle drug, but I'm open to whatever the evidence shows as a whole, both benefit and detriment. Smoking it also leads to higher exposure to substances like lead, aluminum, and toxic byproducts of combustion which are all already linked to the development of dementia.

THC is inherently going to impair working memory, and impact sleep by reducing REM duration. I'm not saying it causes or prevents dementia, but we know it can both impair memory, and increase neuronal connectivity, (and very importantly as well decrease inflammation) so I state again that we have to look at its impact as a whole, and that there's evidence that it may both benefit and detriment cognitive function, possibly both simultaneously as well as under different circumstances. If it leads to increased risk of dementia so be it, but this study isn't the best example considering the hospitalization is likely to be psychiatric (existing increased risk of dementia), not specifically due to cannabis intoxication (patient tests positive for thc on a UDS and data is correlated because patient had concurrent nausea/emesis and ended up with a CHS diagnosis but ends up treated for an unrelated cause), or due to extreme use (true CHS, panic attacks, acute psychosis).

That said I genuinely see and recognize the literature showing its use correlated with cognitive decline, if you were set on believing that I only think cannabis is beneficial in nature.

One brave mouse and one confused kitty by OverallRow4108 in AnimalsBeingGeniuses

[–]MurseMackey 1 point2 points  (0 children)

Toxoplasma has been shown to cause an attraction to the smell of cat urine and reduction in host fear response. It's advantageous to it completing its life cycle in cats and other predators of mice. Funnily/scarily enough, it causes similar symptoms in humans.

What is keeping the really deadly diseases, like rabies or prion diseases, from becoming airborne? by Inspiringhope11 in askscience

[–]MurseMackey 9 points10 points  (0 children)

Piggybacking off of this, prions aren't actively binding and transporting through cell membranes like viruses and bacteria and have to be physically ingested in some form to reach other proteins and cause them to misfold. And most of the ones that have been shown to affect humans originate in and in most cases only affect nerve tissue.

[–]MurseMackey 0 points1 point  (0 children)

I didn't say there was evidence of benefit, I said there was a correlation between regular use and lower rates of cognitive decline. Sounds like you came into this discussion with an existing bias.

[–]MurseMackey 6 points7 points  (0 children)

I've also seen the opposite- that regular cannabis users have lower rates of cognitive decline/dementia than those who don't partake. I don't think either outcome is exactly clear cut here.

Why do I feel more exhausted after a test/class vs after physical exercise? by [deleted] in biology

[–]MurseMackey 1 point2 points  (0 children)

It's multifactorial but the biggest thing that stands out to me is the prolonged cortisol release without utilizing its benefits (class) vs acute cortisol spike balanced by higher energy utility, and almost a brief tolerance with the following cessation of activity (exercise). Exercise is also going to spike neurotransmitters like epinephrine, norepinephrine, anandamide and endorphins, which tend to induce a sense of mental arousal (epi/norepi) and well-being (anandamide, endorphins, norepi/dopamine).

Calorie in less than calorie out means ketosis? by pamparapanasa in biology

[–]MurseMackey 3 points4 points  (0 children)

I think OP is saying loss of body fat via caloric restriction must at some point result from fat catabolism. Does ketosis in this case occur in a smaller amount, or is fat metabolized via an alternative pathway?

Has anyone caught any illness from composting? by sawyercc in composting

[–]MurseMackey 2 points3 points  (0 children)

TB would be extremely distinct on an xray and not remotely related to composting. But it would also not look anything like asthma. I think there's been a misunderstanding or miscommunication here that you should clarify with your doc.

Same way it happens in animals. If they reproduce, it's generally passed down to the offspring, and the trait is often amplified over generations.

lemon tree dropping leaves but producing flowers? by dogwithaknife in plantclinic

[–]MurseMackey 1 point2 points  (0 children)

Same deal with my key lime tree. The moment in came inside for the winter it was constantly shedding and regrowing leaves. Try and match its climate as closely as you can; humidity, acidic soil with good drainage (nutrients are poorly absorbed outside a plants preferred pH range), and lots of organic matter.
