Learning by Practice

This is about one such workshop that I attended on Literature search on PubMed ...at UCMS 

Mnemonics to Boolean operators.

 Use of AND operator for ‘terms search’ will lead to less results while use of OR operator will lead to more results. Isn't it interesting for example

Search Query                  Items found

   (Health) AND Literacy    5716

(Health) NOT Literacy       2348666

 (Health) OR Literacy         2357336

Secondly,  use of MESH, the National Library of Medicine's controlled vocabulary thesaurus. It consists of sets of terms naming descriptors in a hierarchical structure that permits searching at various levels of specificity. For example for the same query 'Health Literacy'. MESH  provide the definition of Health Literacy -  'Degree to which individuals have the capacity to obtain, process, and understand basic health information and services needed to make appropriate health decisions.' The year in which this term was introduced i.e. in this case Health Literacy was introduced in the year 2010.  It further lists the subheadings just like: organization and administration, trends, utilization and so on.  The search can be restricted to MeSH Major Topic and one can exclude MeSH terms found below particular term in the MeSH hierarchy.   I am listing one such Tree structure for the Entry Terms: Literacy, Health:     All MeSH Categories Health Care Category Health Care Facilities, Manpower, and Services Health Services Preventive Health Services Health Education Consumer Health Information Health Literacy Lest I forget again I thought let me put ‘learning to practice’  about the use of operators and MESH more will follow later . I am thankful to Dr. Navjeevan Singh, Professor, Pathology, UCMS   and PubMed Expert Searcher Ms. Vasumathi Sriganesh from QMed Knowldge foundation for providing me the opportunity to attend this workshop on Sunday
