Your Digital Library
MBG 8680Shiffman Medical Library
Key to Access: Library Web Site
http://www.lib.wayne.edu/shiffman
•Links to all databases, catalogs, e-books, e-journals, news
•Hours, contacts, maps, services
•Remote access instructions
Objectives
To provide an overview of basic resources– Databases (to find articles and full text publications)– Catalog (to find journals and books)– Other tools
To increase awareness of services for you To increase awareness of amount/pace of new
information and resources
Does the Library Have?
Catalog: “Imagine”
Linked from Shiffman site or
http://www.lib.wayne.edu/imagine
Catalog Searches
Books– Paper & e-books with links
Journal titles– Paper & e-journals with
links
Other: media, microforms, databases, web sites
Especially important
– Which library?– Location?– Years covered?– MEDLINE abbreviation
Not Found in Catalog?
Visit, call or e-mail reference
Order via Interlibrary Loan (no charge)– Order as soon as possible
No charge from “other side of campus”
Databases
Database is a searchable archive of structured information– Record: all information about an item– Field: information about an item is stored in a field
Bibliographic databases– Fields: author, title, journal name
Molecular biology databases– Sequence, protein translation, source organism
The Question
What is insulin’s role in postprandial hypotension in diabetes patients?
Context: physician notes a severe drop in blood pressure after eating meals. Already knows insulin is suspected of playing a role.
Objectives
What kind of information would you like to find?
What would it look like if you found it?
What should be included?
What should be excluded?
First Steps
1. Write down key concepts
2. Expand with related terms and synonyms
Example: treatment of heart disease
HEARTcardiaccardiovascular
DISEASEdysfunctionabnormalitydisorder
TREATMENT
therapy
therapeutics
drug
surgery
Next Step: Decide on Limits
Time Limits?– Last six months– Last year– Last five years
Size of Retrieval?– One-two relevant articles?– Comprehensive?– Reviews?
Languages? Gender? Research type? Publication type?
Choosing a Database
MEDLINE– The primary source for clinical literature
Science Citation Index/Web of Knowledge– Larger number of research and basic science
journals
BIOSIS (Biological Abstracts)– Breadth of inclusion and full coverage of basic
science aspects
MEDLINE
Primary clinical database with increasing number of basic science journals
WSU offers MEDLINE via PubMed (free) or OVID (restricted)– OVID’s current benefit to you is link to catalog for
journal information
MEDLINE: Try it
Via home page or – http://pubmed.gov
Results? Consider . . .
Are the articles relevant? Too much or too little? Are you satisfied?
Insulin’s role example
CONCEPTS– Insulin– Insulin’s physiological effects– Postprandial period– Hypotension– Diabetes mellitus– Control of cardiovascular responses– Vasodilation– Cardiac output
Terms
Medical Subject Headings (MeSH)
Insulin Postprandial period Hypotension Vasodilation Diabetes mellitus Digestive physiology Blood pressure Eating
Keywords Postprandial
hypotension Low blood pressure Fall AND blood pressure meal
Multiple Term Combinations
Try it:– Insulin AND postprandial period– Insulin AND hypotension– Postprandial period AND hypotension– Insulin AND vasodilation– Diabetes AND hypotension– Insulin AND meal– Digestive physiology AND hypotension
Building a Search
Insulin (MeSH term)– Example: insulin[mh]
Hypotension?– Example: Hypotension OR hypotensive OR (blood
pressure AND fall) Postprandial?
– Example: Postprandial period[mh] OR postprandial OR digestive physiology[mh] OR eat OR food OR meal
Building a Search cont’d.
Insulin’s relationship with vasodilation?– OR (insulin AND vasodilation)
Limiting to English language?– AND Eng[la]
Enter into PubMed search window
AND, OR, Boolean Operators
DOGS CATS
Dogs OR cats: either, or, or both
ANDAND (Intersection)
DOGS CATS
Dogs and cats in the same record
Test Search
((insulin[mh] AND (hypotension[mh] OR hypotensive[tw] OR (“blood pressure” AND fall)) AND (postprandial period[mh] OR postprandial[all] OR digestive physiology[mh] OR eat*[tw] OR food[tw] OR meal[tw])) OR (insulin[majr] AND vasodilation[mh]) AND eng[la])
PubMed
Over 11 million citations from mid-1960s to the present (before 1960s Index Medicus)
Controlled vocabulary (MeSH) helps to focus Provides links to “some” full-text e-articles Updated daily “Related articles” feature for additional citations New e-books with links Loansome Doc (miuwsu)
PubMed
Can be time consuming because of size Quick searches can be dangerous MeSH terms updated annually Includes literature from over 70 countries but
has a North American bias and may omit relevant literature
Additional databases required for comprehensive basic science literature
Science Citation Index
Now in Web of Knowledge with:– Social Science Citation Index– Journal Citation Reports– HighlyCited.com
Why use it?
Science Citation Index
Strengths– More basic science, research journals than
MEDLINE– Citation tracking (no other database has this)– Enables easy date limitations
Weaknesses– No controlled vocabulary – only keywords– Limited user interface– Maximum of 500 records per search
Example:
Sandler MP, Bax JJ, Patton JA et al. – Fluorine-18-fluorodeoxyglucose cardiac imaging
using a modified scintillation camera
Journal of Nuclear Medicine 39(12): 2035-2043 DEC 1998
Why Use Web of Knowledge?
You can find articles:– Written by an author– Written about a topic or person– That cite a particular author in the list of references– That cite a particular article in the list of references– Published within the last few days, weeks or
decades– Published in a particular journals
Why Use Web of Knowledge? cont’d
How often an article has been cited The list of references from an article
Also, – Journal Citation Reports
Relative importance of a journal: “impact factor” Journals in a discipline or sub-discipline ranked by impact
factor, number of citations, other metrics
BIOSIS (Biological Abstracts)
Two choices: Silver Platter or “BasicBIOSIS” in First Search
Strengths– Increased coverage of research and basic
biology journals compared with MEDLINE– Good coverage of animal sciences and animal
models for disease
BIOSIS cont’d
Weaknesses– Has only minimal controlled vocabulary– Interface not user-friendly
Try it:
Try the search in both Web of Knowledge and BIOSIS via Silver Platter
(insulin AND postprandial AND (hypotension OR (blood pressure AND fall))) OR (insulin AND vasodilation)
Other Publications
