Recent additions to the NLM Drug Information Portal include clinical experience with drugs and dietary supplements
From the NLM-TOX-ENVIRO-HEALTH-L Digest – 2 Oct 2014 to 7 Oct 2014 (#2014-19)
The National Library of Medicine (NLM) Drug Information Portal (http://druginfo.nlm.nih.gov) is a free web resource that provides an informative, user–friendly gateway to current drug information for over 53,000 substances. The Portal links to sources from the NLM, the National Institutes of Health (NIH), and other government agencies such as the U.S. FDA.
Current information regarding consumer health, clinical trials, AIDS–related drug information, MeSH® pharmacological actions, PubMed® biomedical literature, and physical properties and structure is easily retrieved by searching a drug name. A varied selection of focused topics in medicine and drug–related information is also available from displayed subject headings.
The Drug Portal retrieves by the generic or trade name of a drug or its category of usage. Records provide a description of how the drug is used, its chemical structure and nomenclature, and include up to 20 Resource Locators which link to more information in other selected resources. Recent additions to these Locators include clinical experience with drugs in PubMed Health (http://www.ncbi.nlm.nih.gov/pubmedhealth), substances reviewed in NLM LiverTox (http://livertox.nih.gov/), information from the Dietary Supplement Label Database (http://dsld.nlm.nih.gov/dsld/), and drug images in the Pillbox beta (http://pillbox.nlm.nih.gov/) database.
Data in the Drug Information Portal is updated daily, and is also available on mobile devices.

Greetings from the National Library of Medicine and MedlinePlus.gov
Regards to all our listeners!
I’m Rob Logan, Ph.D. senior staff National Library of Medicine for Donald Lindberg, M.D, the Director of the U.S. National Library of Medicine.
A comprehensive plan to reduce the number and impact of suicides in the U.S. recently was announced by the U.S. Surgeon General…
The Surgeon General’s National Strategy for Suicide Prevention is available at surgeongeneral.gov.
Meanwhile, a helpful introduction to suicide symptoms is provided by the American Society of Suicidology in the ‘overviews’ section ofMedlinePlus.gov’s suicide health topic page. A helpful guide about what to do if someone is suicidal is provided by the Mayo Foundation for Medical Research and Education in the ‘prevention/screening’ section of MedlinePlus.gov’s suicide health topic page.
The Mayo Foundation for Medical Research and Education also provides a helpful website, ‘Considering suicide? How to Stay Safe and Find Treatment’ in the ‘coping’ section of MedlinePlus.gov’s suicide health topic page.
MedlinePlus.gov’s suicide health topic page contains links to the latest pertinent journal research articles, which are available in the ‘journal articles’ section. Links to related clinical trials that may be occurring in your area are available in the ‘clinical trials’ section. From the suicide health topic page, you can sign up to receive email updates with links to new information as it becomes available on MedlinePlus.
To find MedlinePlus.gov’s suicide health topic page, type ‘suicide’ in the search box on MedlinePlus.gov’s home page, then, click on ‘Suicide (National Library of Medicine).’ Links to health topic pages devoted to depression, mental health and behavior, as well as social/family issues are accessible within ‘related topics’ on the right side of MedlinePlus.gov’s suicide health topic page.
As the Surgeon General’s report notes, improving prevention to offset a sobering rate of suicide is gaining new momentum in medicine and public health. We wish the Surgeon General’s National Strategy for Suicide Prevention every success.
Before I go, this reminder… MedlinePlus.gov is authoritative. It’s free. We do not accept advertising …and is written to help you.
Reminder: NLM Gateway Changing
On December 1, 2011, the Lister Hill National Center for Biomedical Communications (LHNCBC) will complete the transition of the NLM® Gateway to the new LHNCBC pilot project. The new site will retain the Web address of the former NLM Gateway. It will have two databases: Meeting Abstracts and Health Services Research Projects in Progress (HSRProj). HSRProj also remains available via a separate search engine through the portal HSR Information Central.
The Meeting Abstracts database contains abstracts from HIV/AIDS, Health Services Research, and Space Life Sciences meetings and conferences. The final update to the Meeting Abstracts database is the addition of the abstracts from the 2010 18th International AIDS Conference which will be completed in December 2011. After this addition, no new meeting abstract data will be loaded.
For additional information on the transition to the pilot project, see the article NLM Gateway Transitioning to New Pilot Project Site.
NLM Gateway Transitioning to New Pilot Project Site
On December 1, 2011, the NLM® Gateway will transition to a new pilot project from the Lister Hill National Center for Biomedical Communications (LHNCBC). The current version of the NLM Gateway provides search access across multiple databases; however, all but one of these databases is available from other NLM sources, and most users of those databases search them directly and do not use the NLM Gateway. Only one database, Meeting Abstracts, is uniquely located on the Gateway system. Although NLM has invested in and supported the NLM Gateway for eleven years, based on current budget limitations and the results of evaluations of the use of NLM Gateway, the Library has recently decided to discontinue this service, as currently configured, and transition to a new pilot project site.
The new site will focus on two databases: Meeting Abstracts and Health Services Research Projects in Progress (HSRProj). A forthcoming NLM Technical Bulletin will provide more information on this new service from the LHNCBC. Once the new pilot system is available in December, the current Gateway URL will redirect any visitors to the new Web site. The Meeting Abstracts database will still be unique to this site, while HSRProj will continue to be accessible from its home site.
The Meeting Abstracts database contains selected abstracts from meetings and conferences in the subject areas of AIDS, Health Services Research, and Space Life Sciences. The last update to the Meeting Abstracts Database is anticipated to be the addition of the 2010 18th International AIDS Conference, which is expected to be loaded in the fall of 2011. After this addition, the Meeting Abstracts database will still be accessible, but no new data will be loaded.
All of the other resources currently accessed through the NLM Gateway will be available through their individual sites (see Table 1). The home sites for these systems are listed on the NLM Databases & Electronic Resources page. This directory of resources is easily located by clicking on the “All NLM Databases” link in the Databases column on theNLM homepage.
Table 1: The NLM Resources, and homepage URLs, that will no longer be available through the NLM Gateway.
If you are accustomed to the NLM Gateway cross file searching function you may want to try using the cross database features provided by TOXNET® and by the NCBI Entrez system.
Figure 1: TOXNET homepage with “Search All Databases” feature.
Figure 2: TOXNET Search All Databases Results Page.
The NCBI global query feature on the NCBI homepage provides a cross database search feature for all of the Entrez databases (see Figures 3 and 4). Selecting “All Databases” in the search box will return a summary search page identifying possible results across all of the NCBI Entrez databases, including PubMed, PubMed Central, BookShelf, NLM Catalog, and the genetic and protein databases such as Gene, OMIM, BLAST, dbGaP, and others.
You can simply bookmark the Web page http://www.ncbi.nlm.nih.gov/gquery to access the global query search feature. However, going to the NCBI homepage may be the easier way to access this function; the NCBI logo on the top left corner of any Entrez-based system links to the NCBI homepage.

PubMed® Mobile Beta provides a simplified mobile friendly Web interface to access PubMed***. PubMed Mobile includes the same basic search functionality and content as Standard PubMed; that is, all search terms and fields work similarly (see Figure 1).
Simply enter your search in the search box and click “Search” (see Figure 2).
The inital (Summary) display includes the article title, first author’s name, journal title abbreviation, and year of publication.
Click “Free Full Text” or “Review” on the Summary search results page to filter your results. Click “Next” to go to subsequent search result pages.
Click the article title to display the Abstract format (see Figure 3).
Not all data provided on the Standard PubMed Abstract format are included (for example, MeSH® vocabulary); to see complete data use the link to Standard PubMed.
Related Citations display below the abstract. On the abstract page, click “Previous” or “Next” to navigate to other citation abstracts. Click the “Back to results” link to redisplay the Summary search results (see Figure 4).
A link to Standard PubMed is available at the bottom of all PubMed Mobile pages.
PubMed Mobile does not include specialized search pages, such as Limits and Advanced search, or added features, such as My NCBI, Clipboard, or LinkOut/Outside Tool. To use these and other PubMed features, display your retrieval in Standard PubMed via the link at the bottom of the screen.

***PubMed is the largest indexer of the biomedical literature in the world. It can be rather intimidating to search the first few times because there are many options to refine your search in order to get tailored relevant results. Believe me, it is worth the effort!
If you would like expert personalized PubMed search advice, please do not hesitate to contact (preferably call ahead!) a reference librarian at your local academic, medical, or public library.
Many academic and medical libraries offer some degree of personalized reference service to the public. These services are largely offered by professionals with a Masters degree in Library Science who have many years experience providing relevant research articles and other resources to a wide variety of health professionals and others. They enjoy teaching both formally and informally.
Please feel free to email me (jmflahiff at yahoo.com) with any questions. I would be happy to work on a question for up to 2 hours and reply within 3 days. No charge.
Here are some PubMed tutorials and guides

[Editor Flahiff's note: I remember when getting citations from 1966 was a big deal!]
More historical journal citations are now in MEDLINE®/PubMed® with the addition of over 48,000 citations from the 1946 Current List of Medical Literature (CLML). The National Library of Medicine® (NLM®) has been converting information from older print indexes that were the precursors to Index Medicus. When the original MEDLINE database made its debut in 1971, it contained citations to journal articles published from approximately 1966 forward. The 1946 CLML represents the 20th year going back in time to enhance access to the older biomedical literature. With the addition of the 1946 CLML citations, the OLDMEDLINE subset contains over two million citations.
NLM also continues the work of mapping the original keywords assigned to these older references so that current MeSH® terms (Medical Subject Headings) are added to the records and available for searching in PubMed.
Additional information about the OLDMEDLINE data project is available.
Heard about a new treatment for Alzheimer’s disease and want to read about the original research? Need to go to the source about a new surgical procedure? Medical articles, written by physicians and scientists just might be the answer.**
Most medical articles are quite technically written and are published in journals which require paid subscriptions (even tho’ they are online!). Examples of medical journals include the New England Journal of Medicine, the Journal of the American Medical Association, and the Lancet.
Medical journals (a type of scholarly journals) differ from popular magazines (as Psychology Today) in appearance, audience, and purpose. Duke University has a great comparison chart on the differences between scholarly journals and popular magazines.
A few great places to get free and low cost medical articles
- Libraries Many public libraries have at least some medical journals. Most college, university, and medical school libraries (and all receiving some state funding) are open to the public and provide some reference services to the general public. These academic libraries vary in the number of subscribed medical journals.
Some hospital libraries are also open to the public.It is best to call ahead and ask a reference librarian to see if the library is open to the public, if they have the article you need, and if you can use their computers and printers. Ask about interlibrary loan from any library where you have borrowing privileges. Your library will try to get any article they do not have from another library (there usually is a charge, upwards of $11.00 or more an article).
- PubMed Centra****l provides access to free articles submitted by authors and publishers. Some articles are free immediately when they are published, others are free on a delayed basis (ranging from a few months to a year). Check the PubMed Central home page for additional information. PubMed Central is a service of the US National Institutes of Health.
- Free Full PDF – Over 80 million free scientific publications

- Docline is the National Library of Medicine’s automated interlibrary loan (ILL) request routing and referral system. The purpose of the system is to provide efficient document delivery service among libraries in the National Network of Libraries of Medicine (NN/LM).
Individual users of NLM’s PubMed and the NLM Gateway do not have access to DOCLINE, but they can make use of its services by ordering documents through Loansome Doc, a document ordering service. All PubMed or NLM Gateway users ordering documents must identify a DOCLINE library or libraries that are willing to serve them (Ordering Library). The health professional performs a PubMed or NLM Gateway search, reviews the citations retrieved, and identifies specific documents to be ordered. Orders are sent to DOCLINE from either PubMed or the NLM Gateway. The NLM PubMed server manages all document-ordering activities.
LoansomeDoc is for people who are not affiliated with a health or medical institution that has a library. (If your institution has a library, just ask a librarian about ordering articles through interlibrary loan). To register for LoansomeDoc, contact the closest medical library.
They can help you set up an account, including payments for articles. You should be able
receive most, if not all, ordered articles via email.
How to Access Journal Articles provides links to information resources and services.Includes links to free articles, strategies for obtaining articles, and paying for full text articles. By Partners in Information Access for the Public Health Workforce.
- Contact the Author Email, fax, or write the author. Most authors are happy to provide a free copy of their articles if asked. Cannot locate an address or fax number? Ask a reference librarian!
- Contact the Publisher An increasing number of publishers are providing free copies of articles to patients, caregivers, and others who do not subscribe to their journals but only need a specific article for personal use.
If the publisher does not advertise this free service, consider contacting them and requesting a specific article. Need help contacting a publisher? Again, ask a reference librarian!
Some publishers which provide free or low cost articles (via PatientInform)
Elsevier Patient Research provides single copies of articles for $4.95. Elsevier publishes over 2,000 journals.
AACR’s (American Association for Cancer Research) policy for free patient access to medical articles—“If You Need It, You Can Read It”—can be found under Information for Readers/Subscribers.
The Endocrine Society For Patients page provides information on how to obtain free articles from its six endocrine research journals.
****Also, note that “The NIH Public Access Policy ensures that the public has access to the published results of NIH funded research. It requires scientists to submit final peer-reviewed journal manuscripts that arise from NIH funds to the digital archive PubMed Central upon acceptance for publication. To help advance science and improve human health, the Policy requires that these papers are accessible to the public on PubMed Central no later than 12 months after publication.”
I hear health sciences librarians are keeping busy advising researchers on how to comply with this.
**When a good summary of an article will do, check out the resources at Summaries for Patients” help patients and others understand medical studies and guidelines
