Objectives By the end of this seminar you will be able to: • Perform a subject search using Medical Subject Headings • Use limits to narrow a PubMed search • Use the Clinical Queries feature to search for clinical research in PubMed@UCSF • Use the Display options • Print and download citations • Link from PubMed citations to full text articles
PubMed MEDLINE • National Center for Biotechnology Information (NCBI) • Approximately 14 million references to the published journal literature • 1950 (OLDMEDLINE) to present in one database • Incorporates all or part of CANCERLIT, HealthSTAR, AIDSLINE, HISTLINE, BIOETHICSLINE, SPACELINE • Links to full text articles
Special URL: http://www.library.ucsf.edu/db/pubmed/ UC-eLinks Links to UCSF full text journals Links to UCSF Library Catalog to check whether UCSF owns a journal and get call no Links to Melvyl Catalog to check which other UC campuses own a journal Request articles not owned by UCSF from other UC campuses Copy and paste PubMed @UCSF
Boolean Operators • OR (use to join synonyms) • Vitamin C OR Ascorbic Acid • doctors OR physicians • tumor OR tumour • injuries OR accidents • AND (use to combine concepts) • Vitamin C AND cancer • doctors AND managed care • color AND vision • injuries AND automobiles
MeSH Translation Table Journals Translation Table Author Translation Table Author Index Search All Fields Forced phrase searching in quotes “” Explode is automatic Truncation (*) turns off mapping Search field tags are available [title] or [ti] Boolean operators processed left to right Search Term Mapping
Why use MeSH? • If you use two or more words in a keyword search there is no guarantee that they will be linked. • MeSH headings are an efficient way to find information on “concepts” or topics where authors use different language to discuss the same ideas. • For example: Keyword search physical therapy Microneedles and other physical methods for overcoming the stratum corneum barrier for cutaneous gene therapy.
When to use keyword search? • Recent publications (in process) • Records supplied by publishers • New phenomenon
Locating MeSH • Do a Title word search; display results in Citation format; identify MeSH OR • Search the MeSH database • Scope Note • Subheadings • Major Topics • Explode
Clinical Queries • Etiology • Diagnosis • Therapy • Prognosis • Clinical prediction guides Example: 1. Studies on the treatment of chronic low back pain 2. Systematic reviews on the treatment of chronic low back pain
Clinical Queries: Clinical Studiestreatment of chronic low back pain
Clinical Queries: Systematic Reviewsphysical therapy to treat chronic low back pain
Topic Search Technique • Separate query into main search concepts • Identify an appropriate MeSH term for each concept • Combine search terms using boolean operators: AND, OR, NOT • Apply Limit options • Refine search
Limit Options • Language (English) • Human or animal studies • Dates • Age groups (All child, adolescent, aged…) • Publication types (Meta-Analysis, ROC, Review, Evaluation studies…) • Subsets (Core clinical journals…) • Major concept
Exercise 1 Meta-analyses on the efficacy of exercise therapy for low back pain Concept: exercise therapy low back pain Publication type: meta analysis
Exercise 1: Search Steps • Search MeSH database for each concept. - Click on MeSH Database on the left- hand column. - Enter exercise therapy and click on Go. - Check exercise therapy. Go to Send to box and select Search box with AND. - Enter low back pain and click on Go. - Check low back pain and select Search box with AND. - Click on PubMed Search. - Click on Limits, select meta-analysis, and click on Go.
Exercise 1 –cont. • Search MeSH Database for each concept.
Exercise 2 - Prevention of danceinjuries
Exercise 3 • Gait training for stroke patients
Exercise 4 • Treatment outcomes of using physical therapy to treat frozen shoulder (bursitis)
Obtaining Journal Articles • UC-eLinks • Link to full text article (UCSF subscription) • Check UCSF Catalog and Melvyl for journal location (print and electronic) • Request articles from journals not owned by UCSF • Interlibrary Services http://www.library.ucsf.edu/info/circ/ilb.html • Document Express: Obtain journal articles owned at UCSF for a minimal fee
