· More than 150,000 deaths from #COVID19 went uncounted in the U.S. in the first two years of the pandemic, a new study in Science Advances finds
· Swiss researchers have found up to 60% of healthcare workers in a medium-size cohort study may have at least one symptom of #LongCOVID

More than 150,000 deaths from COVID-19 went uncounted in the U.S. in the first two years of the pandemic, according to a new study in Science Advances. Researchers used machine learning to evaluate death certificates from March 2020 to December 2021, and estimated that 19% more COVID-19 deaths occurred than originally reported.

Two recent prevalence studies showed the impact of Long COVID on Americans. The first, an electronic cohort study of over 600,000 active military personnel, found that 42% had at least one symptom more than 30 days after contracting COVID-19.

New issue of #TheSickTimes includes a study that found no evidence that wearable alerts improve pacing.

Not super surprised by this.

The alerts themselves can trigger emotional and sensory exertion.

The data they're generally tracking includes just one type of stressor (physical) - I have yet to find a wearable that can (for example) track emotional overload via voice characteristics; track cognitive load via things like "time spent on computer"; track sensory stimulation via light and sound levels and rate of change.

The proportion of time spent resting and type of rest is a critical factor that is also generally not tracked: vertical vs horizontal vs reclined; physical vs cognitive vs sensory and emotional; degree of stressors and type of stimuli present.

As long as a trial fails to track rest as well as the different types of exertion, impact will be buried in the noise.

A new review in Dovepress states that Long COVID, myalgic encephalomyelitis (ME), and postural orthostatic tachycardia syndrome (POTS) should be classified as neuroimmune disorders.

Metformin has been shown to reduce the risk of Long COVID. Why isn’t it more widely used? - The Sick Times

Recent studies add evidence to a prior phase 3 clinical trial, suggesting that taking the diabetes drug during acute COVID-19 reduces the risk of long-term symptoms.

Yes - its something like 800 million people around the world. And the percentage of children is even more frightening - 20-25% of kids. Data are from the (great) reporting on Long Covid from #TheSickTimes https://thesicktimes.org/
