  • Research Ideas
  •  In thinking about establishing a research
    program, it is important to consider what habits
    investigators need to cultivate in order to be
    successful in their chosen field.
  •  
  • Be a good listener
  • Good researchers learn as much as they can
    from those around them. They learn from their
    patients, from the observations if fellow staff
    members at all levels, and from the accumulated
    knowledge of other investigators in the field.

3
2. (Read, Read and Read)8 Reading papers in
your field, regardless of how finite it may seem
when one first approaches it, is enormous and in
becoming a clinical researcher one must have a
firm grasp, both deep and broad-based, of the
field of ones inquiry, and not uncommonly
several related fields as well.
4
  • 3. Attend national, if possible, international
    meetings.
  • If all that one knows about a field is what
    has been published in professional journals, one
    is at least a year out of date. The most recent
    information is usually presented at meetings.
  • Network
  • When you begin to work in an area, it is
    very important to get know the most influential
    people, particularly in your own field at
    internationally level.

5
5. Present at meetings or submit to journals
As soon as you can, submit and present
scientific data at meetings you have targeted as
the most important in your field. This will allow
you to obtain criticism and feedback on your work
and to become known to other investigators.   6.
Results that get results
6
  • Choosing an Area of Focus
  •  At some point, an investigator needs to decide
    on an area on which to focus. Obviously, this
    decision is of great importance, and it should be
    based on a number of factors, including the
    following
  • From your postgraduate education. It assume you
    are the best in your field of postgraduate thesis
  • Interest in the area and questions that need to
    be asked, as well as interest in and compassion
    for this patient population.

7
3. The availability of patients and necessary
equipment and/or methodology. 4. Is there a
niche? 5. The availability of collaborators and
mentors. 6. What is hot?
8
Supportive Environment and peer Groups   One can
rarely do research in isolation. A desirable
situation is one in which other individuals are
working in the same or related areas. It is
important to work in a culture where research
productivity is valued, and where recognition is
given for it.  
9
Categories of Papers Regular Research Articles
This category is intended for full scale basic or
clinical studies, usually up to 5000
words.   Brief Reports/Clinical Reports This
category ifs for smaller, self-contained
laboratory or clinical studies including series
of cases illustrating a novel therapeutic
approach or clinical observation.
10
Rapid Communication. This category is for
fast-breaking new work, which is of the great
potential interest and can be succinctly
presented.   Review Articles They are usually
invited. Indeed, their writers should be expert
in that field.   Letters to the Editor These
should briefly report single experiments and
cases of clinical interest or respond to recent
articles.
11
Choosing a Journal In thinking about where to
submit a paper for publication, several issues
must be considered. The researcher should ask,
How important is this study, and what readership
would be interested in it? Sending an article to
a journal when there is little or no chance of
the journal accepting it may take a great deal of
time and may delay publication of the article
until its importance to the field is diminished.
12
In preparing a journal article, it is important
to follow the instructions to authors for those
particular journals.   One good way to decide
which journal is appropriate for an article is to
look at its reference list. This shows where
other articles in this field are being
published.   And finally, step-by-step you will
be patron of a specific journal!!!!!!
13
Submitting Process After choosing the journal
and making the manuscript according to its
format, you should submit it to the editor with a
covering letter indicates  Title of the
manuscript Conflict of interest Name of
authors Demand for fast track service Type of
submitted article And finally why you chose that
journal
14
Conclusion Like most academic tasks, writing
journal articles is a skill that is developed
over time.   Becoming a productive clinical
researcher requires one to publish, so he or she
must jump in, write up the results, submit the
manuscripts, promptly return the revised
manuscript, resubmit rejected manuscripts and
learn throughout the process

Analysis of papers submitted to the BMJ
37

Rejection - Why?
  • Wrong Journal
  • Offering too long
  • Faults in presentation
  • Retrospective study
  • Statistics
  • Failure to standardise methods
  • Groups in trial not comparable

38

The object of a Scientific Paper
  • Enable the reader to
  • Assess the observations you made
  • Repeat the experiment if they wish
  • Determine whether the conclusions drawn are
    justified
  • Basic structure
  • IMRAD

39

Structure of a Scientific Paper
  • Introduction (What question was asked?)
  • Methods (How was it studied?)
  • Results (What was found?)
  • And
  • Discussion (What do the findings mean?)
  • Titles, Authors, Abstract, References

40
Introduction
41

Introduction
  • What do I have to say ?
  • Is it worth saying?
  • What is the right format for the message?
  • What is the audience for the message?
  • What is the right journal for the message?

42

Introduction (2)
  • Brief
  • Clear (What is the question)
  • Instructions to authors
  • Clarify what your work adds (Importance)
  • Balance of references (For and Against)
  • Dont overdo it

43

Introduction (3)
  • Two main functions
  • Awaken the readers interest
  • Direct and to the point
  • Be informative
  • What is known
  • State the Question

44
Methods Materials This, too, is an easy
section.   You know you did, and here you merely
report it. However, science relies on
replication.   Try not to frustrate the reader
the same way, as you were frustrated.   In a
clinical study, make sure the subjects, including
controls, are defined both clinically and
demographically so well that analogous
populations could be gathered by others
45
Do not refer to unpublished methods List the
source of any materials that are not routinely
available.   Indicate how the data were handled
and refer to any statistical procedures you may
have used.   Methods is usually divided into
subsections that include study design, study
population, treatments (Interventions),
measurements, and statistical analysis.
46
Study Design   Method of randomization, type of
blinding, type of Control Parrarel -group or
Crossover design   Multicenter or single center
47
Study Population Inclusion and exclusion
Criteria Specify Requirements as to health
condition, age, gender, ethnic background, weight
and height The criteria used in the diagnosis of
the disease should be given Species, strain and
serotype of microorganisms Writers must give a
complete picture of the patients disease
severity and duration, any concomitant health
problems, and concomitant medications Ethic
Subsection
48
Treatment In the treatment subsection, the writer
specifies the drugs, the dosage regimens
evaluated, route and method of administration,
and composition of the placebo used. Measurements
The writer describes in the measurements
subsection the end points that define clinical
efficacy Patients safety Follow up visits
49
Statistical Analysis The writer states whether an
intent to treat analysis was used in which case
the outcomes of all patients were analyzed with
the group to which they were originally assigned,
whether or not they completed the protocol. If an
additional analysis was performed on patients who
completed the trial as planned.   Two tailed or
one tailed ? Level

Results
52

Results
  • Results section - two key features
  • 1) Overall description of major findings
  • 2) Clear and concise data

53

Results (2)
  • Use a mixture of text, tables and figures
  • Give the actual number of results plotted
  • Establish how comparable your groups were
  • Degrees of accuracy?
  • Condensed results (Range, Mean Spread)

54

Tables and Figures
  • Title text - brief
  • Convey max. amount of information
  • Placed and punctuated uniformly
  • Legend
  • Fully self -explanatory
  • Tables and figures must be mentioned at least
    once in the body of the text

55

The Illustrations
A picture is worth a thousand words if it is
a good one
56

FILE FORMATS OF FIGURES
  • EPS (preferred format for diagrams)
  • PDF (also especially suitable for diagrams)
  • PNG (preferred format for photos or images)
  • Microsoft Word (figures must be A4 portrait,
    single page only)
  • PowerPoint (figures must be a single page)
  • TIFF
  • JPEG
  • BMP
  • EXL
  • Good general tools for image conversion include
    GraphicConverter on the Macintosh, PaintShop Pro
    for Windows, and ImageMagick , which is available
    on Macintosh, Windows and UNIX platforms.

57

Results summary
  • Easiest part to write
  • At the start of study you should know
  • type of record traces
  • tables to be included
  • Text will tell the story
  • Tables are the meat
  • Illustrations for dramatic impressions
