How to do a Literature search for your research and scientific publication BhaskarBorgohain4
In the age of information boom it may be challenging task to find relevant information for your research work. its like finding a needle in a haystack. After initial readings from textbooks and library journals you may want to first search in Wikipedia, google, google scholar and then go to Pubmed, Medline, science direct , wileyonline, science.gov, cochrane library etc to formulate your keywords based on your research question. read a medical dictionary to find synonyms of the keywords and brainstorm with your supervisor, peers, friends etc to get more key words to search again and find the right search strategy. do not forget to look for Grey literature like unpublished Thesis works from reputed universities, proceedings of conferences of reputed professional associations as well. keep records using a software like end-note, Rayyan etc. References of authors must be recorded as you go along.

Tom Selleck Health: A Comprehensive Look at the Iconic Actor’s Wellness Journeygreendigital
Tom Selleck, an enduring figure in Hollywood. has captivated audiences for decades with his rugged charm, iconic moustache. and memorable roles in television and film. From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

Guidelines and Protocols come in a range of different forms - there are some database products we provide that specialise in providing these such as BMJ Best Practice and UptoDate.. Some claim to be based on a comprehensive analysis of the evidence and demonstrate this, some are put together by expert panels linked to medical associations and their evidence may be more selective.
Sometimes they are highly structured database resources such as the BMJ Best Practice and UptoDate, sometimes they are found within larger databases that collate a range of information from single studies through to systematic reviews and guideline summaries.
Sometimes they are referred to as Guidelines, sometimes as protocols and sometimes as First Consults. They often include information produced for patients to understand their condition.
For instance BMJ Best Practice provides a highly structured organisation of summary information related to a specific condition.
Here is an example of UpToDate’s Guidelines page on Cleft Palates – similarly it summarises under key headings such as etiology, diagnosis and management.
Most guideline summaries should have a references tab, where you can critically consider the sources used.
Many of the specialist Clinical Practice guideline resources are organised around key topics or areas of medical practice but can aslo manage simple searches of a specific condition.
Then you have resources such as Clinical Key that search across a broader spectrum of guideline sources and also pull in from a wider range of other sources resources… in this search for instance there are 9 guidelines and a 3 first consults found but also a large number of citations pulled in from Medline as well as bookchapters, images and other full text articles.
Note that you can also filter by article type to hone in on these, you would certainly be interested in focussing in on systematic reviews for instance on your research topic.
Go to live demonstration, show a number of the Systematic Reviews are coming from Cochrane.. and being indexed within Medline but that it is also bringing in systematic reviews from a wide range of other organisation..
Medline is one of the largest and databases collating medical information from a wide range of sources and indexing it with specialist medical terms which is why the second part of this workshop will focus on it.
However back to our purpose.. To look at Guidelines and in this case First Consults (closely aligned to protocols).
Clinical Key has identified 9 guidelines related to our topic in some way..
Of these you will notice they are coming from a range of specialist journals and professional organisations. First one looks very on topic and when you go into a guideline you will notice similarly to other guidelines the structuring and organisation of summary information about the condition.
The First Consult in particular appears to be like a more traditional guideline.. Covering epidemiology, screening, prevention, diagnosis and treatment. Under resources you will find the summary of evidence used to inform this guideline.
??Follow lead from Cranofacial Journal, takes to Pubmed (associated with Medline) and out to journal site where payment option given.. What do you do if faced with this? Go back to OneSearch.
Spend some time investigating one and then share in your group?
Q: How well does it provide an overview of the topics associated with diagnosis, prevention and treatment etc of this condition?
Q: How easy is it to investigate the reference sources or evidence used to develop these summaries, do they appear reliable?
Record one of the references of interest to you? (all look at one area, such as Management or treatment approach)
Q: How might you use these guidelines to support your own research?
Any observation on the use of a resources such as Clinical Key rather than others?
As indicated by this Online Evidence based resources list (in ACQ)– different resources have different strengths in terms of the types of resources they bring together and how broad they are.
One of the broadest databases for collating of medical research and journal articles is Medline/PubMed (you may have found much of the information bringing you back to these). With it’s origins in the US National Library of Medicine is has a strong US focus.
Embase is also very broad in its scope of biomedical research literature but it has a greater emphasis on European locations. This is why any systematic review must consider these two databases as primary sources.
Both MEDLINE and EMBASE are provided here at UWA through the OVID database platform. We selected this platform because of the very controlled way it allows us to build a search strategy using highly developed medical indexing terms…. And so this is what we will be trialling today.
Other more specialist databases exist such as Cochrane and JBI Connect (from the Joanna Briggs institute) – as we saw these focus on systematic reviews and guidelines developed through their research collaborations using specific methodologies they have developed.
Databases such as TRIP and OvidMD are interesting because of the way they help you to visualise the level of evidence of results returned (example of TRIP and OvidMD).
Then you have more limited but specialist databases such as CINAHAL focussed on Community and Allied Health, AUSTHealth focused on Australian research bodies and DOSS the specialist Dental database (these can be linked to from the Dentistry Libguide).
Medline and Pubmed do give you more capacity to do this.
Can you save and export some results to and Endnote Library? Can you add the access date and a label for the level of evidence?
Databases such as TRIP and OvidMD are interesting because of the way they help you to visualise the level of evidence of results returned (example of TRIP and OvidMD).
Then you have more limited but specialist databases such as CINAHAL focussed on Community and Allied Health (not as relevant to Dentistry), AUSTHealth focused on Australian research bodies and DOSS the specialist Dental and Oral Science database (this can be linked to from the Dentistry Libguide).
?
A broad database such as Medline or EMBASE – that has a well defined and developed list of medical terms that can be searched at a granular level and into which items have been indexed can be a lot more powerful and exact in returning results on the specific conditions, treatments etc that you are searching for.
For this reason we are going to look at the skills required to develop effective search strategies that break down your search question and how you can apply them within a database such as Medline and powerful interface such as OVID.
Moving on from what was covered in the lecture we will work out a search strategy for this example question then search Medline/PubMed,
Going back to basics, it is always important – especially when trying to research a very specific medical intervention – to spend time thinking about and breaking down your research question to develop research terms and parameters (or limits).
This requires you to first break down your research question into the core distinct concepts and then thinking about related terms or synonyms that might be used in different databases or turn up as keywords or free text searches..
What are some other terms we could use for this research question?
Work with the students to create a search strategies for this topic for use in Medline or Pubmed,
ToothpasteAND fluoride risk AND young children risk
Brushingchildren OR risk factors
Teeth caretoddlers OR
“fluoride toothpaste” AND (child* OR toddler*) AND risk

Boolean search techniques – such as truncation, phrase searching, nesting – can increase accuracy of search results
Work with the students to create a search strategies for this topic for use in Medline or Pubmed,
You don’t need to necessarily try all of the search terms you have developed. Can sometimes be better to start with less but have a bank of possible terms to try.

“fluoride toothpaste” AND (child* OR toddler*) AND risk
Medline (1960) represents a much more highly selected range of medical journals as selected by the US National Library of Medicine which have been catalogued using MeSH – Medical subject headings.
PubMed (1996) as well as Medline contains in process and ahead of print citations, out of scope articles (from within Medline journals), some full-text OA journals, Book citations from NCBI
As such you will get more results in Pubmed but unlikely to be as relevant to biomedical science as those just in MedLine. Pubmed is easier to search.
MeSH – a thirteen level hierarchy of medical terms (27,883 descriptors + 87,000 entry terms) Medical Subject Terms
Includes Supplementary Concept Records (SRC)– contain specific examples of chemicals, diseases and drug protocols.

In indexing or mapping the terms to subjects came up with flurosis – discovered as a specific MeSH indexing term used to describe impacts of too much fluoride in children’s teeth.
Can add these in as separate terms and then I have the capacity to decide how to join them together and fluidity with choices – especially if I log in..
Search six brings concept 1 “fluoride toothpaste and risk factors” together
Search 7 combines this with items specifically indexed with the subject term flurosis
Search 9 brings together this specific topic with more general terms of toothbrushing and toothpastes.. At each try you should be looking over your results to see if they are matching your search interests or deviating from them.
Search 10 brings together additional limits to search 9 – age groups and to review articles only.

How you can use citations to expand your search
Article: Dental fluorosis decline after changes to supplement and toothpaste regimens
DOSS, Medline, Web of Science, Scopus and Google Scholar all have citation searching capability. Web of Science and Scopus tend to have the best coverage, however.
Note that you will probably get slightly different results in each of these databases as they only give results for the journals they index.
