Health Info on the Web

18 06 2012

Finding disease information that is more detailed than the general consumer information available on most health websites can be a challenge. We put together these suggestions and hope they may lead to helpful info for families having to make the difficult searches.

Google Scholar Search

Google’s Scholar Search “provides a simple way to broadly search for scholarly literature. From one place, you can search across many disciplines and sources: peer-reviewed papers, theses, books, abstracts and articles, from academic publishers, professional societies, preprint repositories, universities and other scholarly organizations. Google Scholar helps you identify the most relevant research across the world of scholarly research.”

Google provides help for understanding Scholar search results. You can also specify your search result preferences (including language settings. Use the Advanced search to focus your search in a variety of ways.

National Library of Medicine (NLM)

The Hepatitis B Foundation provides an overview presentation of NLM resources that are most relevant to families searching for disease information. (Click here for a printer-friendly version.)

PubMed

The National Library of Medicine (NLM) maintains MEDLINE, a database of indexed citations and abstracts to medical, nursing, dental, health care, and other sciences journal articles. PubMed is a service of NLM that provides free access to MEDLINE (other access services may charge fees).

Knowing how to effectively use PubMed can help you get more relevant search results and prevent the results from being too numerous. NLM provides this tutorial for using PubMed. Use the column on the left to navigate the tutorial (includes “previous” and “next” buttons). Pay attention to the “MeSH Vocabulary” section—using MeSH terms will help you refine your searches.

Be aware that search results obtained through PubMed provide abstracts and citations. Sometimes pthe full text (or links to it) is provided, but often, journals require that you purchase the full text of articles. One way to reduce or eliminate this cost is to locate the journal in a library near you in order to read the article.

MedlinePlus

MedlinePlus is a service of NLM that provides consumer-level health information. Any search will reveal a variety of links to reliable sites with information on your chosen topic. In addition, MedlinePlus offers multimedia presentations on a number of disease topics.

LocatorPlus

Use LocatorPlus to search for resources in the physical National Library of Medicine. This service is mainly useful only to people who intend to go to the actual NLM and check out a resource.

Do you have some search tips to share? We’d love to hear about them!

PubMed: Obtaining Full-Text Journal Articles

23 04 2010

In our previous PubMed articles, we discussed finding free articles online and conducting more effective searches. In this PubMed post, we discuss ways to get full text articles that are not free online.

Visit Your Libraries

Local Library

Check with your local library to see if they have the journal in question, or if they can get it in for you. This may be your only recourse for getting full articles at no cost, even if you have to wait awhile to get the journal.

Nearest Medical Library

If your local library doesn’t have or cannot get the journal or article you want, contact your nearest medical library. Call the National Network of Libraries of Medicine at 800-338-7657 or visit their website to locate your nearest library. (You can’t call this number to get help finding information, but they can help you locate a library.)

Order Online Through PubMed

Loansome Doc

PubMed is primarily for medical students and professionals, which is why it provides a service called Loansome Doc that enables you to 1) find medical libraries in your state serving the general public, and 2) easily and conveniently order journal articles through PubMed.

When viewing an article’s abstract, clicking on the “Send To” link opens a box from which you can select “Order.” Clicking the “Order articles” button will direct you to enter your Loansome Doc login information.

PubMed Loansome Doc

Ordering option for Loansome Doc

Registration for Loansome Doc is free; you only pay when you order an article. To sign up for Loansome Doc, visit the Loansome Doc signup page.  The first step will help you locate a medical library near you. You will need to contact the medical library of your choice to get signed up with them.

If you are not a healthcare provider or student, the medical library will consider you an “unaffiliated user.” Each library will have different criteria regarding unaffiliated users, pricing, and document delivery formats (hardcopy vs. electronic, e.g.).

LinkOut

If you click on an article’s title in your PubMed search results, you can click “LinkOut” at the bottom of the abstract to see online sources providing full text. You do not need a Loansome Doc account for these, but you may have to set up an account on the website of the online source to place an order.

Viewing options for ordering under LinkOut

So to sum up:

  • Try your local library or visit a medical library (if you have one close to you).
  • If you are planning to order articles on a relatively frequent basis, sign up for Loansome Doc so you can place all your orders from within PubMed.
  • If you are planning to order articles relatively infrequently, try ordering from a LinkOut service.




PubMed: Refining Searches with MeSH

5 04 2010

Our previous PubMed article described how you could search for journal articles using simple search terms, like you would on the Internet. However, if you want your search to be more targeted and effective, you should use MeSH search terms.

What’s MeSH? Sounds messy.

MeSH (Medical Subject Heading Terms) terms are medically-oriented keywords. Because PubMed is indexing medical journal articles, you will generate better search results if you use medical terms used by PubMed. Previously, our approach was:

  1. Enter keywords into PubMed
  2. Get results

Using MeSH terms, our approach will be:

  1. Enter keywords in MeSH to find MeSH terms
  2. Enter those MeSH terms into PubMed
  3. Get more targeted results

Great! How do I do this?

First, go to the MeSH homepage. Then enter a keyword in the search box, and click the “Go” button. In this example, we’ve entered “hepatitis” and the results are displayed below the term.

Finding MeSH terms

Every term or phrase listed here by number is a MeSH search term. Below each term is the definition for that term. Find the terms that most closely match what you have in mind, and check the box next to them. Then click the “Send to” drop-down box and choose “Search Box with AND.” A second search box appears above your search results with the MeSH term inside.

Sending MeSH terms to the new search box

Now you can add additional MeSH terms to further refine your search. Try entering “child” in the field at the top, and click “Go” to get MeSH terms related to “child.” Then click the box(es) next to your desired terms, and send them to the search box as you did in the step above.

If you want to exclude a term, choose “Search Box with NOT.”

If you want to search for articles that contain at least one of the terms you’ve sent to the search box, but not necessarily all of them, choose “Search Box with OR.”

Once you’ve sent your desired MeSH terms to the search box, click the “PubMed Search” button directly below it. You will then see a page of results, like the example below:

You can now interact with the search results as we discussed in our previous PubMed article. Watch the blog for future articles on PubMed searching.





Searching Parents…Meet PubMed!

15 03 2010

When you’re a parent searching for information about your child’s medical condition, it doesn’t take long to exhaust the online resources most readily available. MedlinePlus…  Mayo Clinic…  WebMD…  But where do you go when you need more?

If you’re ready to dig deep, you can turn to journal articles for more information and research. One way to search journal articles is to visit NIH’s PubMed website.

You can enter keywords into the search box at the top of the page, and you will get results. But you’ll get a lot of them, and some won’t really be as targeted as you’d like. There are a number of ways to get better results, and we’ll be discussing these in upcoming posts, but today we’re going to show you the most economical: Filter by free text!

First, enter some keywords to search by and click the “Search” button. In our demo shots below, we use “chronic pediatric hepatitis.”

PubMed homepage

The next page will shows you some results. Depending on your personality, you’re either happy to see the 488 results returned by this search, or reeling with shock at the thought of sifting through 488 results! But for today’s purposes, we’re going to narrow our results the thrifty way, by clicking on “Free Full Text” on the right side of the screen.

Search results for "chronic pediatric hepatitis"

Below you can see the 61 free, full text articles available to you. Click on the “Free article” link under the citation.

Search results showing only those with free full text available

PubMed shows you services on the right that provide the article’s text free online. Choose one and start reading!

Finding Health Info on YouTube

29 06 2009

YouTube is a vast library of online videos.  There truly is something there for everyone.

This amount of content makes narrowing a search challenging, but doable.  It is possible to find quality health-related videos on YouTube.

Creating An Account
Go to YouTube.com and create an account by clicking the Sign Up link on the top right.

As you’re filling in the blanks on the sign-up page, notice the little box that says, “Let others find my channel on YouTube if they have my email address.”

Channels are people’s accounts. Think of YouTube as a giant TV and everyone signed up, including you, is hosting his/her own channel. Yikes! Very crowded, but there are gems in the crowd.

Once done with the sign-up page, you’ll go to another page where you’ll type in your email and password.  At the end of this process, YouTube sends you an email asking you to confirm your account.  Follow the email instructions and you’ll soon be on your very own YouTube account page.  When you get there, look in the upper right corner of that page.  If your user name is there, you’re signed in and ready to go.

Your Page
Take a look at your personalized home page. The first option you have is Add/Remove Modules.  Click on that to go to Account Settings, where you pick and choose what you want to see on your home page (e.g. add/remove subscriptions, recommendations, friend activity, ect.).

Subscriptions is next (videos from channels to which you’re subscribed), then Recommendations (videos recommended by YouTube that you may like), followed by Friend Activity (videos your friends have uploaded), Featured Videos (videos that are featured on YouTube), and Videos Being Watched Now (which is self-explanatory).

Searching YouTube
Finding health channels to subscribe to is easy―just type a keyword (e.g HIV/AIDS, pertussis, H1N1, etc.) into the search box.

The search brings you results from Channels (other users’ accounts) and Playlists (a user-maintained list of videos).

Browse the channels and playlists and when you find something you like, click the gold Subscribe button on that page.

YouTube-CDC-Streaming-Health

Subscribing allows you to get up-to-date videos from the channels or playlists you select and feeds those videos to your home page.

When looking for a range of information providers to subscribe to, sorting by Playlist can be beneficial, as playlists may be made up of videos created by that particular user, or videos the user likes that are created by others, or a combination.

YouTube - health search

You can also click on the Community tab (see above) and browse videos by categories, shows, movies, channels, contests and events.

Once you’ve identified a health information source and determined its credibility, click subscribe.

The new videos from that user’s channel or playlist will then show up on your YouTube home page under subscription.

It is that easy, so jump in and don’t forget to find some funny vids to get you through the day.
