La dizione #Asintomatico compare più spesso in pubblicazioni scientifiche con (o senza ma con evidente riferimento a) varia ulteriore #specificazione e rivolto a soggetti #affetti (es. infezioni: #asintomatici #infetti, pazienti infetti asintomatici, casi asintomatici, ecc.) 1/14
ma #senza #manifestazioni cliniche (sintomi e segni). Tuttavia pare che il termine #asintomatico abbia anche un significato più ampio, cioè di soggetto #senza #manifestazioni cliniche il cui esatto #stato di #salute, di #affetto o meno, sia #determinabile solo con un #test. 2/14
Almeno così potrebbe sembrare dalle letture di un profano come me che ha fatto alcune ricerche. Ad es. su #PubMed sono molteplici le pubblicazioni che esplicitano che gli #asintomatici possano essere anche #non #infetti e #negativi alla diagnostica. 3/14

My team and I are seeing a big spike in requests from people looking for #COVID_19 related related. The good news is that there are already a bunch of efforts to highlight, curate, and make this work available.

Here's some (and feel to suggest others)!

Una cosa sobre el Nuevo #PubMed Tienen un botoncito de feedback para decirles cosas. Yo les digo cosas como que necesito el enlace a MeSH para hacer las búsquedas. Me responden cosas como: "We suggest entering search terms without search tags for the most comprehensive retrieval"
It's a trap! ¿Por qué? Porque os va a hacer la búsqueda de los términos en TODOS los campos. He hecho la prueba y he metido una frase tal cual, sin las comillas y sin etiquetas de campo. Y el resultado ha sido un desastre: sólo un registro.
La cosa cambia si pones esa misma frase entrecomillada o si le indicas dónde quieres que busque. Porque por mucho que se empeñen, su niño no es el más listo. La utopía de buscar tipo Google en PubMed está muy bien, pero PubMed no es Google.

Since a few #medlibs asked... I've dug up some of my favorite examples of bad / wtf MeSH indexing, along with a few of my go-to searches to show how automatic term mapping (ATM) in #PubMed can do unexpected things.

A thread 👇
"The importance of good images in using hair to screen for breast cancer" ( has been indexed with "Magic"[Mesh]. I'm guessing it's because the next letter, on page 2 of pdf, has the title "Science or Black Magic?" #medlibs…
I mentioned this one during the #medlibs chat:

MeSH fun includes being indexed with "Telepathy"[Majr]. I assume based on context it should maybe have been "Telepathology"[Mesh]. But also... did you know there is a Mesh term for telepathy?
