The National Library of Medicine (NLM) is currently involved in MEDLINE year-end processing (YEP) activities. These include changing the Medical Subject Headings (MeSH) main headings as well as Supplementary Concept Records that standardize names and associated numbers for chemical, protocols, and diseases that are not main headings. The MeSH edits include existing MEDLINE citations to conform with the 2015 version of MeSH, and other global changes.
November 19, 2014: NLM expects to temporarily suspend the addition of fully-indexed MEDLINE citations to PubMed. Publisher-supplied and in process citations will continue to be added.
Mid-December 2014: PubMed MEDLINE citations, translation tables, and the MeSH database will have been updated to reflect 2015 MeSH.
For details about the impact on searching from November 20 to mid-December, see: Annual MEDLINE/PubMed Year-End Processing (YEP): Impact on Searching During Fall 2014.
For background information on the general kinds of changes made annually, see: Annual MEDLINE/PubMed Year-End Processing (YEP): Background Information.

Take a break (22 minutes) and watch this video presentation by Victoria Brazil, a physician and medical educator from Australia. She talks about what educational modalities and interventions are effective in medical education. Spoiler alert: the answer is everything and nothing.

One question we’re often asked in our classes is how to keep up with changes to PubMed and other NLM Resources. There are lots of changes, but there are several resources as well. Whether your interest is PubMed, History of Medicine, disaster medicine, or NCBI databases, you can find a blog, Facebook page, Twitter account, or even Pinterest board to follow. For the full list of ways to connect with NLM, see their social media page.
In addition to the NLM accounts, you can also follow the social media of your National Network of Libraries of Medicine Region or one of the Centers (like us, the National Library of Medicine Training Center).
Finally, we always recommend subscribing to the National Library of Medicine Technical Bulletin. You can be among the first to know about changes to PubMed and other important information that may impact your use of NLM resources. They also have a searchable archive that can be useful for finding when particular changes occurred. For example, you can search for “bolded” to learn that PubMed began making your search terms appear in bold in 2011.

What do nuns, surgeons, and transplant recipients have in common?
No, it’s not the beginning of a joke — they’re all new MeSH terms for 2015!
I mentioned last week that I love exploring the newly released MeSH terms. Here are a few more highlights.
In the information science branch, Common Data Elements, Data Curation, Datasets as Topic, and Printing, Three-Dimensional have all been added to the vocabulary.
Social Norms, Social Skills, Courage, and Craving have been added to the behavior branch, and I’m glad to see the addition of Military Family as well.
Several forms of elimination and absorption have been added, including Intramuscular Absorption and Lacrimal Elimination.
Palliative Medicine, Electronic Cigarettes, Culturally Competent Care, and Grounded Theory also made it into the MeSH vocabulary this year.
Want to make a suggestion for next year? Send it to NLM!

I don’t know about anyone else, but I always look forward to seeing what new terms have made it into MeSH for the coming year. New MeSH for 2015 has been released, and I recommend taking a look by tree subcategory. You can find changed descriptors and deleted descriptors as well.
A couple highlights from my first look a the new MeSH:
In the Diseases branch of the MeSH tree, Rhinitis, Allergic, Chikungunya Fever, Allesthesia, Corneal Injuries, and Premenstrual Dysphoric Disorder are some of the new additions.
New Investigative Techniques include Bioprospecting, Controlled Before-After Studies, Health Information Exchange, Historically Controlled Study, Non-Randomized Controlled Trials as Topic, Patient-Specific Modeling and Protective Factors.
Frankincense has been added as MeSH heading. And in case you’re wondering, Gold is already a MeSH heading, and myrrh oil is a supplementary concept. High Fructose Corn Syrup was also added, which is one that I would have guessed to already be in MeSH.
In the diagnostics and therapeutics categories, Diving Reflex, Fluorine-19 Magnetic Resonance Imaging, Diet, Paleolithic, Robotic Surgical Procedures have all been added.
Enjoy exploring the new MeSH terms, and share with us on Twitter or Facebook your favorite new MeSH term!

NLM just added a new special search query to the Topic-Specific Queries page. The strategy is not limited to U.S.-based articles.
Follow this link to view the new search strategy.
The Topic-Specific Queries page can be found from PubMed’s home page. Look for the link in the center column labeled PubMed Tools.
Keep up with all the new features and changes to PubMed by subscribing to the Technical Bulletin.

Work your way through this updated tutorial to view tips to help you effectively search for drugs, chemicals and other substances in PubMed.
There are nine brief modules with video demonstrations. You’ll find guidance on substance-related Medical Subject Headings (MeSH), using the MeSH Database, searching with pharmacological action terms, converting special characters in systematic names, and using tags in searching.
When you’re done, there’s a quiz. You can find the tutorial at this URL: http://www.nlm.nih.gov/bsd/disted/drugs/intro.html
