@socrdoc a young adult in our extended family also had low ferritin D and B12 along with many of the other symptoms. is there a good study on what is causing the nutrient deficiencies?

@michael_hoerger Your data shows San Mateo county as very high, but https://t.co/8NMKPWlb95 shows only one sewershed for the county with low Sars-CoV-2 levels, declining for last 2wks. How to reconcile? (https://t.co/g1Mvpo7qLG for the link directly to Redwood City in San Mateo County)

[Rep. Brian Fitzpatrick 🇺🇸 @RepBrianFitz]

This week, along with @RepPaulTonko, I introduced the Indoor Air Quality Act—bipartisan legislation that takes a critical step forward in my efforts to protect our community and students from poor indoor air quality.

Although progress has been made to address outdoor air pollution, efforts on indoor air quality have been largely unacknowledged and underfunded. Despite this lack of action, studies show that indoor contaminants can be 2-5 times—and occasionally 100 times—higher than outdoors.

Read more about our bipartisan solution to address this issue below: ⬇️

I am in still in disbelief - and so appreciative - that indoor air quality is *finally* getting the attention it deserves. Grateful to @BioCommission for making "Masters of the Air" a focus of their Commission. #HealthyBuildings

[Joseph Allen @j_g_allen]

Kudos to @RepPaulTonko and @RepBrianFitz for introducing the bipartisan Indoor Air Quality and Healthy Schools Act. I was proud to advise on this, and I support it. #HealthyBuildings

@sri_srikrishna @ashishkjha @sri_srikrishna have you looked at the raw data on SF test positivity? it's odd.. seems like the baseline is ~500 tests/day and positivity of 8%+, and then there are repeating bursts of 3 days in a row with 1500 tests/day and 2% positivity, which brings avg down.

@andrewchen https://t.co/EFNyq2ZuLE his books were avail on Google Books when I read them in 2010 or so, highly recommended

@JeromeAdamsMD Maybe the "like" button absorbs some % of people's positive feelings, so negative skew in the comments? Also, "flame wars" began on the internet as soon as email and usenet newsgroups existed. Something about human psych, no empathy when typing into a box vs talking to a person

@xabitron1 Surface area of lungs is ~500x the nasal passage. But nasal turbinates and nasal valve create turbulence, flinging 30-50% of inhaled particles into mucosa where they're stuck/filtered. (source: Google/PubMed papers) So nasal protection reasonable as one layer of defense.

@j_g_allen What's the best "smoking gun" paper with the best evidence of a causal relationship between PFAS and human health?

@wraylb I remember Kwok & Carter.. 30 years later there is still at least one neuron holding on to the authors' names

[gjohn @gjohn]

@ConanMacDougall @Bob_Wachter Is asymptomatic positive % defined as # positive test results divided by total # of tests administered (including those with no results yet)? The denominator should instead be # of completed tests. Who can work to change this?

how did you get this on the 2nd guess?? I used 2 standard probe words (that are not usually this informative) plus the confidence boost from knowing you'd solved it with just 2 guesses.

@palisadesops Is it planned to be operating tomorrow Mar 25?

@asenkut @auren @patrick_oshag @felicis Depending on the company's revenue mechanics you might be better served by comparing $revenue to a lagged $ spend metric from some previous month, depending on sales cycles and revenue recognition. Otherwise growth/investment will look like inefficiency.

@jaltma But look, Opendoor did interview customers in the early days. Probably ppl said "no I would use a traditional realtor" and the founders still bet on their vision. That's good. Don't trust ppl's hypothetical stmts. Listen, learn, build your own informed model and informed bets.

@EricTopol Is this a back-to-school bump? (At this point shouldn't we align different geographies by calendar date versus data of first N infections, to be able to spot trends?)
