Episode Objectives

During this tutorial episode:

You will practice using PubMed's "Advanced" search page

You will practice applying "English", "Review", and "Systematic Reviews" filters to a pubmed search.

You will complete a quick search in ProceduresConsult

You will be reminded of the sources you can use for help in the future

Learning issue #9: Rate of Gastrointestinal Problems in Med Students

During episode 4 you prepared term lists for this PubMed search. 

Your term lists should look something like:

"medical students" OR "medical student"

gastrointestinal OR gastric OR intestinal OR stomach OR bowel* OR dyspepsia OR pyloric OR pylorus OR duoden* OR ulcer* OR gastritis OR reflux OR gerd OR gastroesophageal OR esophageal OR Crohn* OR ibs

PubMed "Advanced" Search

1 of 2In this case, you really want articles that are so focused on medical students that either --

"medical student"

or

"medical students"

-- is present in the title of each record retrieved.

This is easy to accomplish using the "Advanced" search feature in PubMed.

  • Click on the "Advanced" link under the PubMed search box.

PubMed "Advanced" Search

2 of 2
  • 1. Use the drop-down menu next to the builder's upper search box to select the "Title" option
  • 2. Paste your --
"medical students" OR "medical student"
 
-- terms into the adjacent search box.

  • 3. Paste your --
gastrointestinal OR gastric OR intestinal OR stomach OR bowel* OR dyspepsia OR pyloric OR pylorus OR duoden* OR ulcer* OR gastritis OR reflux OR gerd OR gastroesophageal OR esophageal OR Crohn* OR ibs
 
-- terms into the second search box.
 
The search boxes  act like a sets of parentheses enclosing the OR'd terms.  The PubMed search engine will compete the OR operations inside the search box before joining the box concepts.
 
  • 4. The default "AND" setting for the operator joining the two concepts is the correct choice in this case.

PubMed Search: Step #8 -- Run Search.

  • If you haven't already done so, click the "Search" button.
  • The search should retrieve over 90 results.
  • About half of the results concern the rate of, or risk factors for, gastrointestinal conditions in medical students.
Retrieval of 50% relevant results is not a bad rate of relevance for a keyword search.
 
  • There are several possible ways to approach reviewing the results list:
  • You may wish to review the complete result list for discussions of specific gastrointestinal conditions of great interest in light of John's case. 
  • Alternately, you may wish to start by reviewing the publication types that you shouldn't miss.  The tutorial will guide you through this approach.

PubMed Search: Step #9a -- English Limit

This search retrieved enough results to make applying  language and publication type limits worthwhile.
 
Limits/Filters are located on the left-hand side of the page.
 
Start by applying an "English" language limit as follows:
  • Click the  "Show additional filters" link at the bottom of the left-hand column.
  • Select "Languages"
  • Click the "Show" button.
A screenshot showing the process of selecting and choosing to show the "Laguage" limit.
 
  • When the "Languages" filter/limit options appear, click on the "English" option.
  • You know you've applied a filter successfully when a check mark appears in front of the filter.

PubMed Search: Step #9a -- Article Type Limit

1 of 3
Next consider applying an "Article Type" limit.
 
It's important that you are aware of :
  • the regular "Review" filter/limit
  • the "Systematic Reviews" filter/limit
"Review" filter:
  • Any article that summarizes the literature published on a topic is a "review" article. 
  • Most review articles are "narrative reviews."  They do not attempt to review all the available evidence, and author bias is expected.
  • However, the review subset is still especially important to students.  Some of the articles retrieved when a "Review" filter is applied, provide basic introductions to a topic.  These introductory reviews can be quite useful to medical students.  Unfortunately, there is no way to limit to the "introductory review" subset alone.
"Systematic Reviews" filter:
 
It is possible to limit to a different subset of review articles, the "systematic reviews" subset.  Several types of reviews are included in this subset:
  • systematic reviews of the literature which critique all the available evidence and then make treatment recommendations. 
  • meta-analyses are systematic reviews that include a re-analysis of the combined data from the reviewed studies
  • practice guidelines published by well known organizations (These are often based on systematic literature reviews and/or consensus of well known experts.)
  • consensus statements produced by panels, or organizations.
A relevant, well-executed, recent systematic review or meta-analysis is considered the highest quality medical evidence.  
 
A narrative review, on the other hand, is close to the bottom of the evidence pyramid.

PubMed Search: Step #9a -- Article Type Limit

2 of 3

Start with the "systematic reviews" limit.  To apply this limit, complete the following steps:

  • Find the "Article Types" section of the Filters column.
  • Click the "Customize" link.  A list of available publication types will appear. 
A screenshot showing clicking of the 'Customize" link, followed by select of the "Systematic Reviews" option, and clicking of the "Show" button.
  • Click the box in front of the "Systematic Reviews"
  • Click the "Show" button.
  • When the "Systematic Reviews" option appears under the "Article Types" heading, click on it.
  • You know you've applied a filter successfully when a check mark appears in front of the filter.

A PubMed record for a relevant systematic review was retrieved, and the full-text is freely available!

PubMed Search: Step #9a -- Article Type Limit

  • Now try clicking on the "Review" filter. 

When two article types are checked in the left-hand column, articles of either type are retrieved (the filters are OR'd).

The PubMed record for another freely available article is retrieved!

ProceduresConsult -- procedure information and videos

We would like you to be aware of one additional resource. 

Unfortunately, John's case provides no learning issues that can be addressed using this resource.  So let's pretend John also had anal pain.  If this was the case, you might need to obtain information about how an to perform anoscopy.

When you want to see a video that will show you how to conduct a procedure and/or written information about the process of performing a procedure, check ProceduresConsult.

 

Accessing ProceduresConsult

Optional -- Want "GetIt!@UNMC" buttons in Google Scholar?

A few quick steps will make "GetIt!@UNMC" links appear  next to Google Scholar search results available in full-text form through UNMC subscriptions.

To make the needed changes in Google Scholar settings:

  • Click the Google Scholar "menu" button.A screenshot of the Google Scholar menu button.
  • Click the "Cogwheel" iconA screenshot of the "cogwheel" icon.
  • Click on "Library Links"
  • Search for -- UNMC 
  • Select the "University of Nebraska Medical Center" option
  • Click the "Save" button.
  • Future Google Scholar search results will contain a"GetIt@UNMC" link whenever the full text is available through a UNMC's subscription or license.

A screenshot shows a "GetIt!@UNMC" link to the right of a Google Scholar hit

  • If, at a later date, you see no "GetIt!@UNMC" buttons; you will have to go through the setting changes again.
Always think twice about the source of items you find on Google Scholar.
 
*Many items available through Google Scholar are journal article or book chapter from reputable, well-known publishers. 

*Many are dissertations published by students after years of study and reviewed by their thesis committees.  

*However, some items in Google Scholar are in non-peer-reviewed journals or newsletters.

*Some are articles in journals published by predatory publishers, publishers that will publish almost anything for a fee.  Some of these publishers will even add authors to works written by others if the 'new author' pays them a fee.

The following optional questions will give you a chance to see if you understand the implications of the various aspects of keyword searching that have been covered by tutorial episodes 4 and 5.

A friend has composed the following search for articles about the signs of toxoplasmosis in a cat:

tox*[Title] AND cat*[Title]

Which of the following article titles will be retrieved by your friend's search (a,b,c, or all of these (d)?

 

 

Another friend wants to see articles about liver problems in patients with heart failure.  He creates the search --

heart[Title] AND Failure[Title] AND liver[Title]

His search retrieves many irrelevant articles like an article with the title "Liver failure in total artificial heart therapy."  Which of the following search strategies would you eliminate retrieval of irrelevant records focused on liver failure?

 

 

A friend composes this search for articles about heart failure:

"heart failure"[Title]

Which of the following articles about heart failure, will be retrieved by your friend's search a,b,c, all or none?

 

 

 

You are working on a search for articles about detection of toxoplasma gondii on the surface of fruits and vegetables.   Your first attempt at this search is shown in the screenshot below.  This first attempt has retrieved many articles about fruit that have nothing to do with toxoplasmosis. 

A screenshot shows construction of a search in the PubMed search builder.  The drop-downs next to the thre search boxes that have been used all have been set to the "Title" option  The first box contains the term toxoplasm*.  The second box contains the term vegetabl*.  The third search box contains the term fruit*.

What would you do to fix the search?

 

 

Which  types of articles are retrieved when a "systematic review" filter is added to a PubMed search (a,b,c, or d. all of these)?

 

 

 

If you needed to search for practice guidelines that were not published as journal articles, where should you search?

 

Which of the following steps are useful when searching Google for a specific article (a,b,c, or all (d))?

 

Which of the following statements is true?

Want to check your resource knowledge?

2 of 2 During this episode, you used:

PubMed to locate relevant journal articles.

You used the "advanced" search to reach the multi-box search builder and specify a title search.

You used the "Systematic Reviews" articles type filter to limit your results to systematic reviews, meta-analyses, consensus reports, and practice guidelines that have been published in journal articles.

You used the "Review" limit to find a narrative review.

PubMed is available through the "Literature Databases" button on the Library's homepage.

ProceduresConsult to find a video and written information describing a procedure.
