Les trucs et astuces qui suivent ne sont valables que pour une utilisation « au quotidien » de PubMed. N'utilisez pas les outils qui suivent pour réaliser une revue systématique ou une méta-analyse !!!!
⚠️ Précaution d'emploi (2/2)

Tout ceci est destiné à faire des recherches rapides, sans se prendre la tête et sans y passer des heures.

Ca ne remplace *évidemment pas* l'aide que peut vous apporter un(e) documentaliste en santé pour des recherches plus fines. 🤓

A #thread on our recent paper in @PLOSNTDs examining ecological #evidence-base for #DiseaseControl management practices for #KyasanurForestDisease #AcademicTwitter #Scicomm #OneHealth; paper led by @SarahBurthe from @MonkeyFever_ consortium
#Diseasecontrol strategies originate through endorsements by Governments/academia/authorities; they're often not field-tested robustly; even when they are, evidence is limited to one sector (cf. #OneHealth #Intersectoral approaches);
#publichealth approaches ought to be contextual & their effectiveness ought to be evaluated, yet strategies for disease control often spread through word of mouth and are sometimes untested;

What happens to hematopoietic transplant recipients who develop #COVID19?

Transplant recipients and transplanters have been asking this question ever since the pandemic began.

Our analysis using @CIBMTR data is out today in @TheLancetHaem thelancet.com/journals/lanha…. 1/
While there have been close to 100,000 papers related to COVID-19 listed on @NCBI @NLM_NIH #Pubmed, there are very few that address outcomes after #COVID19 in #BMTsm patients, a few are listed in the next tweet: 2/

Happy Wednesday! Join me, won't you, for another #medlibs rant thread / tweetorial in which I discuss the age group filters in #PubMed. I'm going to use the search

[ cyclic vomiting[tw] ]

as my example. You have been warned. 😅 screenshot to show the age filters in PubMedscreenshot of age filters in PubMed where you can select to
My question that I referenced in this tweet was asking about what is really happening with these filters. I eventually got an answer, but I had to do the work myself to really get it. Sharing here with y'all since it's not documented elsewhere.

A few caveats: these age filters are all based on Medical Subject Headings, or MeSH terms, which immediately restricts their usefulness since not everything in PubMed is indexed with MeSH. That's not to say they are 'bad' though - they can be very helpful. For example:

¿Conoces la historia de PubMed? Seguro que buscas en el asiduamente, pero sabes de dónde viene?
En este hilo te lo cuento 1/11
PubMed permite el acceso gratuito X Internet desde 01/1996 a la base de datos MEDLINE. Y siendo verdad también hay que señalar que PubMed no solo es MEDLINE aunque su mayor componente sea este. Más información ¿Pero no es lo mismo PubMed que MEDLINE? 2/11
ccamposhugf.wordpress.com/2012/02/23/per…
El antecedente de MEDLINE es el Index Medicus (1879 x John Shaw Billings, mensual). Una versión acumulada anual (CUMULATED INDEX MEDICUS) 1960-2004. Una versión reducida 1970-1997 (ABRIGDE INDEX MEDICUS) con la indización de revistas nucleares.

Nuevo vs. Legacy #PubMed PubMed: son 2 sistemas independientes en los que la indexación se realiza en diferentes momentos, por lo que las adiciones, eliminaciones (por ejemplo, eliminar duplicados) o actualizaciones de registros no surten efecto al mismo tiempo en ambos lugares.

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.

There may be variations in your search results due to enhanced synonymy, addition of plural forms, better British/American translations, unlimited truncation, and slight differences in how the new system indexes words and phrases.
I have performed the following search: pregnancy [ti]
In old PubMed the result is 167194 references and in the new #PubMed search engine 167213 references.
I know that the search algorithm has changed but the search by tags should be the same result.
Response of NLM: "individual search field results may be slightly increased using the updated technology as it is more robust in ignoring special characters associated with citation content".

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" (ncbi.nlm.nih.gov/pubmed/11333872) 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

ncbi.nlm.nih.gov/pmc/articles/P…
I mentioned this one during the #medlibs chat: ncbi.nlm.nih.gov/pubmed/21640057

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?
