I've not been paying much attention, what's the fashionable variant right now? Got covid again and it feels a lot worse than last time, which was a couple of years ago.

JN.1 is the hottest new strain they everyone is trying to get. It doesn’t have a real name because names scare the people. It’s still Omicron, with air quotes and eye rolling.

If you are in the United States, have a functional liver and kidneys, and are not on any interacting medications, go to test2treat.org to get free Paxlovid before the Feds bury it in a landfill in New Mexico on New Year’s Day.

This is interesting, if not exactly surprising. It demonstrates that i) it is a real physical phenomenon and ii) by extension it is a mechanism that is difficult to discern by normal testing. Both should be uncontroversial and considering the invasive nature of the test, this is not going to be that useful on its own. I think the main value here is to narrow in a cohort for further study, and I wouldn't be surprised if it turns out this is the group suffering from mitochondrial dysfunction for example.

"Study helps explain post-COVID exercise intolerance"

https://news.yale.edu/2023/12/19/study-helps-explain-post-covid-exercise-intolerance posted:

(..)
When a patient reports shortness of breath or exercise intolerance, physicians will usually run tests—such as CT scans, echocardiograms, or pulmonary function testing—to determine whether the symptom is being caused by limitations in the lungs or the heart since, typically, it's one or the other. In some cases, however, neither lung nor heart function appears to be hindered.

Evidence has emerged that patients with long-term COVID-19 who experience these symptoms tend to fall in the latter category, with standard tests identifying no heart or lung limitations.

For these patients, the next step is typically a cardiopulmonary exercise test in which the patient rides a stationary bike or runs on a treadmill while sensors track physiological activity up to the point the person feels they have to stop the exercise. However, there are still patients for whom this type of test reveals no cause of exercise intolerance.

Yale is one of very few places in the United States where a more advanced version of this evaluation—the invasive cardiopulmonary exercise test, or iCPET—is available. For the test, pressure-sensing catheters are inserted into the pulmonary artery, a main blood vessel in the lungs, and at an artery in the wrist. As patients exercise, physicians track various measures to observe how well the heart, lungs, blood vessels, and muscles are functioning.

In the new study, 55 patients were evaluated for post-COVID exercise intolerance, including 41 who showed no evidence of heart or lung limitations after initial tests. They then underwent iCPET.

"We found that despite the fact that the heart was pumping oxygenated blood that the lungs were providing adequate amounts of oxygen for, the extraction of oxygen by the body's tissues was compromised in patients who had symptoms of exercise intolerance after COVID," said Peter Kahn, a pulmonary and critical care fellow at Yale School of Medicine and lead author of the study.
(..)
Another benefit of this research, said Kahn, is dispelling potentially harmful myths that have emerged around post-COVID exercise intolerance. Some patients have been told that their symptoms are a result of deconditioning or decline from lack of physical activity and that reconditioning alone would address the intolerance.

"Our findings contradict that hypothesis and instead support the idea that there is a clear physiologic abnormality underpinning the symptoms experienced by our patients," said Kahn.


While iCPET revealed that impaired oxygen extraction was a common occurrence among the post-COVID patients in the study, the test is invasive, time-intensive, and not offered in most medical centers. With this finding in hand, however, future studies may be able to uncover alternative, less invasive tests that can achieve the same results, the researchers say.

"Our findings not only provide the beginnings of a mechanistic insight into exercise intolerance in those with post-COVID exertional intolerance but also provide an opportunity to consider less invasive diagnostic testing and begin a renewed focus on targeted therapies," said Kahn.

Study proper:
"Differential Cardiopulmonary Hemodynamic Phenotypes in PASC Related Exercise Intolerance"

https://openres.ersjournals.com/content/early/2023/12/07/23120541.00714-2023 posted:

Abstract
Background Post-acute sequelae of COVID-19 (PASC) affects a significant portion of patients who have previously contracted SARS-CoV-2, with exertional intolerance being a prominent symptom.

Study Objective This study aimed to characterize the invasive hemodynamic abnormalities of PASC-related exertional intolerance using a larger data set from invasive cardiopulmonary exercise testing (iCPET).

Study Design & Intervention Fifty-five patients were recruited from the Yale Post-COVID-19-Recovery-Program, with most experiencing mild acute illness. Supine right heart catheterization (RHC) and iCPET were performed on all participants.

Main results The majority (75%) of PASC patients exhibited impaired peak systemic oxygen extraction (pEO2) during iCPET in conjunction with supranormal cardiac output (CO) (i.e., PASC alone group), On average, the PASC alone group exhibited a “normal” peak exercise capacity, VO2 (89±18% predicted). Approximately 25% of patients had evidence of central cardiopulmonary pathology (i.e., 12 with resting and exercise HFpEF and 2 with exercise PH). PASC patient with HFpEF (i.e., PASC HFpEF group) exhibited similarly impaired pEO2 with well compensated PH (i.e., peak VO2 and cardiac output >80% respectively) despite aberrant central cardiopulmonary exercise hemodynamics. PASC patients with HFpEF also exhibited increased body mass index of 39±7 kg·m−2. To examine the relative contribution of obesity to exertional impairment in PASC HFpEF, a control group compromising of obese non-PASC group (n=61) derived from historical iCPET cohort was used. The non-PASC obese patients with preserved peak VO2 (>80% predicted) exhibited a normal peak pulmonary artery wedge pressure (17±14 versus 25±6 mmHg; p=0.03) with similar maximal voluntary ventilation (90±12 versus 86±10%predicted; p=0.53) compared to PASC HFpEF patients. Impaired pEO2 was not significantly different between PASC patients who underwent supervised rehabilitation and those who did not (p=0.19).

Conclusions This study highlights the importance of considering impaired pEO2 in PASC patients with persistent exertional intolerance unexplained by conventional investigative testing. Results of current study also highlights the prevalence of a distinct high output failure HFpEF phenotype in PASC with a primary peripheral limitation to exercise.

"Bilateral Vocal Cord Paralysis Requiring Long-term Tracheostomy After SARS-CoV-2 Infection"
sad lol

quote:

Given continued stridor, as well as the new onset of dysphagia, left-sided weakness, paresthesias, and gait unsteadiness, she was admitted for a comprehensive multidisciplinary workup.
...
Her left-sided weakness and paresthesias were thought most likely to be functional in nature, although a SARS-CoV-2-related etiology could not be excluded. Her vocal cord paresis was thought likely to be related to the preceding SARS-CoV-2 infection.
...
Notably, weakness and paresthesias had resolved by the time of her first outpatient neurology follow-up appointment, consistent with a transient SARS-CoV-2-related effect versus a functional disorder precipitated by the significant stress caused by her breathing difficulties at the time of her initial presentation.
we think SARS-CoV-2 is causing impairment of her vocal cords, she's got other neurological symptoms, so the most likely explanation for the latter is... she's panicking about her vocal cords and that's causing her other neurological symptoms

I’ve been harvesting the fabric straps off Auras as they get soiled (my kids are gross) in anticipation of running out of the big boxes I ordered and being left with the crappy blue rubber banded ones. Alternately you could just order the elastic from like Joanna’s or similar and cut it to the right length yourself and staple it on after removing the blue straps. (Also works with the vented auras and their confusingly irritating shorter straps that make them too tight).
Good needle nose pliers to remove the old staples carefully so you don’t trash the mask, you can line up the holes with the new staple if you’re careful. Hell you could probably even sew them on for more comfort.

In scruffy's opinion, they make a lot of noise about "NIOSH-tested!!!!" and intentionally ambiguate that with "NIOSH certified" when the Flo mask is not NIOSH certified as an n95 (or anything else) and the results document from the lab that did the test has this in the header
