@martinmoline@Gus_Noriega@nytimes 1/n Vamos a hacer una cosa, el que no entiende de ciencia te va contar algo que obviamente vos ya sabes, pero decime donde me estoy equivocando.
@martinmoline@Gus_Noriega@nytimes 3/n Ha’eri and Wiley [1980] le pusieron microesferas de albumina al interior de las máscaras (source control) y las buscaron en las heridas luego de 20 operationes. “Particle contamination of the wound was demonstrated in all experiments.” Mhhh. europepmc.org/article/med/73…
@martinmoline@Gus_Noriega@nytimes 7/n Lahme et al [2001] “surgical face masks worn by patients during regional anesthesia, did not reduce the concentration of airborne bacteria over the operation field in our study. Thus they are dispensable.” europepmc.org/article/med/11…
@martinmoline@Gus_Noriega@nytimes 9/n Claro que si, porque hay muuucho más que esto. Bahli [2009] “no significant difference in the incidence of postoperative wound infection was observed between masks groups and groups operated with no masks.” semanticscholar.org/paper/Does-evi…
@martinmoline@Gus_Noriega@nytimes 10/n Karolinska Institute [2010] “Our decision to no longer require routine surgical masks for personnel not scrubbed for surgery is a departure from common practice. But the evidence to support this practice does not exist,” wrote Dr. Eva Sellden. pubs.asahq.org/anesthesiology…
@martinmoline@Gus_Noriega@nytimes 11/n No te quiero aburrir, pero tengo más... y eso sin entrar en el estudio de ratones sirios en SARS-Cov-2 estudio que concluye que hay que usar máscaras y muestran mayor carga viral en los pulmones de los ratones enmascarados.
@martinmoline@Gus_Noriega@nytimes 12/n Entonces decime, para que usabamos las máscaras? Y volviendo 'ausencia de evidencia, no es evidencia de ausencia'. Con los pibes no se suele experimentar pero siempre hay algun loco.
@martinmoline@Gus_Noriega@nytimes 14/n Y yo te diría que si no te fijaste que en el paper de Nature el tiempo máximo por intervalo es 5 min, no tengo palabras.

1/n Probably this is not too well known, I know I didn't though @andrey_akinshin has a blog post about it. If your software uses a lot of Stopwatch [QueryPerformanceCounter] and we do for showing a lot of detailed measurements to our users, there are a few gotchas. That is 30%.
2/n That measurement for me was strange, its like: How on earth could I miss 30% of the runtime cost just calling the Stopwatch Start/Stop on a core routine? It's the kind of thing that just don't escape the WTF?!?! label.
3/n I hypothesize, the only reason how that can happen is because we are somehow transitioning into kernel space. It didn't add up, at all. And when I mentioned @ayende though similarly to me.
How better the world would be if people would exercise some brain activity before activating the muscles to hit keyboard keys at pseudo random. The masks ninjas clearly have absolutely no advantage.
And that is IF I would look away from evidence. It is highly probable that most influenza strains comes from... GUESS WHERE!!!! Asia, and I am pretty sure that is not a shock to anyone. A simple google search: "where does influenza comes from" suffices
Obviously a young and inquiring mind like @jamesbleekerPL would notice also that massive (no other word would suffice) influenza on 2019... Let me guess... What did happen at the end of 2019... Anyone said 13 different SARS-Cov-2 sequences by December??? independent.co.uk/news/world/asi…
I live in a country that has mandated masks even in outdoors (where I don't use it, period). I vote with my wallet, BUT, for maximum civil disobedience this is my mask for when I have no choice (shops, kids school, etc). It reads: "Doesn't filter aerosols. Doesn't work for CV19"
For maximum irony, this is a triple layer, high quality, medical grade mask (even though ear loop design is quite crappy IMHO), next step: N95 (but they are a pain to wear). So when anyone says something I tell: "Come on? Haven't you read the evidence?" and then I explain.
Then I point them to the hilarious European CDC study and explain the how 19 out of 20 are just bad evidence and the only one that its actually good, is compatible with higher infection rates. Details here:
1/ Because by judging from other countries (mine for example) that is completely true. Just took my kid to primary school, all parents packed together (with their 'masks on' of course). Who would have known? Right?
2/ But let's make it fun. Every thread is better with a poll. Do people use masks properly in your city? Keep distance, don't touch it, over the nose... you know the usual.
3/ That's why I wrote this small rant a few weeks ago. Because using PPE in the wrong way is worse than not use it at all.
1/ There is absolutely no discussion that if you have a disease that doubles its size every 3-4 days and 2% of those infected requires hospitalization you are going to have a quite difficult situation to deal with. Not even a newbie modeler would disagree with @neil_ferguson
2/ But as @gidmk told me once in one of our initial exchanges (and respectful disagreements): "Everyone comes into epidemiology for the uncertainty and stay for the nuance" (if I recall it correctly, corrections please). The entire response rest on those nuances, let's dissect.
3/ At least in my mind there is no doubt that the Ro of SARS-Cov-2 is very high (we estimated 3.3) and if we account for the UK variant we are probably 30% up from there. So, we can say we agree probably up to the decimals level.
