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)
