Research & Reporting
• Proposal
• Research
• Submission• Decision
![Page 4: Publishing your manuscript, Drenth (ppt, 362 kb)](https://reader033.vdocuments.us/reader033/viewer/2022060122/559667b01a28ab79128b45d2/html5/thumbnails/4.jpg)
The basics of writing a paper Before you begin
• 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?
• Where should I publish the message?
![Page 5: Publishing your manuscript, Drenth (ppt, 362 kb)](https://reader033.vdocuments.us/reader033/viewer/2022060122/559667b01a28ab79128b45d2/html5/thumbnails/5.jpg)
Basic principle
Make sure that readers know where they are, where they are
going, and whySo
The best is that you, as author know where you want to go and
why
![Page 6: Publishing your manuscript, Drenth (ppt, 362 kb)](https://reader033.vdocuments.us/reader033/viewer/2022060122/559667b01a28ab79128b45d2/html5/thumbnails/6.jpg)
Why publish?
• Expand medical knowledge• Hey, you want some brownies!
– Career prospects
• It is nice to be the expert– 4 articles on Proflox in peptic ulcer disease
make you the world expert
• Research not published = not done– If it is not listed in Pubmed, consider it not
done

Why publish?
• Because you have something important to say• To change practice• To promote thought or debate• To allow examination of your work• “Fame and the love of beautiful women”• Money• To entertain/divert/amuse• To educate• Career advancement

Writing an article
• Try to align the content presentation of your paper with the Journal’s interest: aim well– Know your stuff, check the journal
– A clinical study is unlikely to end up in J Biol Chemistry
– The case report “healing of reflux esophagitis with pantoprazol” is unlikely to be published now in NEJM

Famotidine for the Prevention of Gastric and Duodenal Ulcers
• First sentence of he introduction– Gastroduodenal damage can be seen on endoscopy
in 20 to 40 percent of people who take NSAIDs. • Last sentence of the introduction
– We compared two doses of famotidine (20 mg twice daily and 40 mg twice daily) with placebo to test the hypothesis that famotidine provides protection against NSAID-associated gastric and duodenal ulcers.
![Page 22: Publishing your manuscript, Drenth (ppt, 362 kb)](https://reader033.vdocuments.us/reader033/viewer/2022060122/559667b01a28ab79128b45d2/html5/thumbnails/22.jpg)
Famotidine for the Prevention of Gastric and Duodenal Ulcers
• First sentence of the discussion– The results of this study show that treatment with a
high dose of famotidine significantly reduces the cumulative incidence of both gastric and duodenal ulcers in patients with arthritis receiving long-term NSAID therapy.
• Last sentence of the discussion– High doses of famotidine were well tolerated and
effective in preventing both gastric and duodenal ulcers in patients with arthritis receiving long-term NSAID therapy.

Introduction
• Three types of introduction• Discussion
– The optimal therapy for peptic ulcer disease is under debate
• Alarmist– Peptic ulcer is a devastating disease and a major
killer in the western world
• Seminar– Peptic ulcer disease is a major public health burden
![Page 24: Publishing your manuscript, Drenth (ppt, 362 kb)](https://reader033.vdocuments.us/reader033/viewer/2022060122/559667b01a28ab79128b45d2/html5/thumbnails/24.jpg)
Introduction
• Be accurate– No misrepresentation of literature– Avoid selective referencing– Avoid tailoring introduction to the results
• Concise and to the point• Put the potential results of the study in
perspective with the literature– Do not give an elaborate review of the
literature here
![Page 25: Publishing your manuscript, Drenth (ppt, 362 kb)](https://reader033.vdocuments.us/reader033/viewer/2022060122/559667b01a28ab79128b45d2/html5/thumbnails/25.jpg)
Methods
• Concise but complete• Do not repeat complex methods
– If your lab discovered alpha pipelemic acid measurement in 1985, do not list the complete method here
• Describe controls• Provide statistical methods• Provide Medical Ethical Committee
approval
![Page 26: Publishing your manuscript, Drenth (ppt, 362 kb)](https://reader033.vdocuments.us/reader033/viewer/2022060122/559667b01a28ab79128b45d2/html5/thumbnails/26.jpg)
Results

• Be sure to include basic descriptive data• Do not overdo with tables and figures
– Figures tell the story– Tables give the evidence
• Do not discuss strengths / weaknesses of your study (here)
![Page 27: Publishing your manuscript, Drenth (ppt, 362 kb)](https://reader033.vdocuments.us/reader033/viewer/2022060122/559667b01a28ab79128b45d2/html5/thumbnails/27.jpg)

Discussion
• Again be concise• Do not restate results or introduction• Explain differences from other studies
• How does your data further the field (what this study adds)
• Place your results in perspective with other results
• Sell but be aware of overstating• Mention limitations

Discussion
• Last sentence• Another puzzle solved
– It is clear that proflox 40 mg o.d enables healing of Forest II peptic ulcer even in geriatric patients
• More research is needed– Further studies are needed to determine the optimum
dosage and duration of therapy• Perhaps possibly
– Proflox may well heal peptic ulcers, but other treatments may be as effective and it is unsure whether peptic ulcers in geriatric patients need treatment at all

References
• Avoid abstracts• Avoid selective referencing
– Mention the co-discoverer• Self citations
– Dr. X is a big proponent of self citation. Out of the 24 references he elects to cite 9 (38%) of his own studies. These 9 represent all Dr. X’s 9 first author papers on Pubmed
• Check for duplicates (happens!)• Political referencing
– Reviewers (references to likely reviewer)– Editors (references to Journal)
![Page 31: Publishing your manuscript, Drenth (ppt, 362 kb)](https://reader033.vdocuments.us/reader033/viewer/2022060122/559667b01a28ab79128b45d2/html5/thumbnails/31.jpg)
Submission
• Check, check, double check– Watch MS Office spell check!
• Favors non-medical above medical terms– sprue -> spree or spruced– We look forward to you reply
• Keep the journal’s format– Title page OK?– Abstract OK?
• Background & Aims vs. Introduction– References OK?– SI units
• mg/dl vs. mmol/l
![Page 32: Publishing your manuscript, Drenth (ppt, 362 kb)](https://reader033.vdocuments.us/reader033/viewer/2022060122/559667b01a28ab79128b45d2/html5/thumbnails/32.jpg)
Writing style
• Active• Short• Plain
![Page 33: Publishing your manuscript, Drenth (ppt, 362 kb)](https://reader033.vdocuments.us/reader033/viewer/2022060122/559667b01a28ab79128b45d2/html5/thumbnails/33.jpg)
Write active
• Not:– Histological analysis by Dr. X of nicely cut
liver samples by the very able technician Y revealed moderate steatosis and hepatitis in the liver of rat A and B but rat C had only minor steatosis and rat D displayed severe hepatitis
• But– At eight weeks livers showed a variable
degree of steatosis and hepatitis

Words editors prefer
• About > approximately
• Has > possesses
• More > additional• Raised > elevated
• Start > initiated
• Study > investigation

Plain is better
• If you can cut out a word do so• Never use long words when short one will do• Never use a foreign phrase if there is an
everyday English equivalent
• Never use passive when active will do– The finger of the physician was inserted into the
rectum– The physician inserted her finger in the rectum

Journal
• Take care in selecting a journal: right platform– Try to aim accurately: Donald Duck or NEJM– A letter of inquiry to the Editor might help
• Follow the specific requirements• References
– Use an automatic reference programme
• Check the cover letter– Is the Editor in Chief still in place– In case of resubmitting: reference to the ‘other’ journal
deleted?
![Page 37: Publishing your manuscript, Drenth (ppt, 362 kb)](https://reader033.vdocuments.us/reader033/viewer/2022060122/559667b01a28ab79128b45d2/html5/thumbnails/37.jpg)
Submission
• Dry run at a (local) scientific meeting – Jot down the questions– See what might be improved

Cover Letter 1
Your cover letter sells your article• Introductionary sentence
– Please find enclosed our manuscript "Proflox improves peptic ulcer healing " intended for publication in Gastroenterology.
• Caption of your study– As already outlined, peptic ulcer disease is a
devastating disease with a high mortality in the elderly. Current therapy includes proton pump inhibition.Although this is an effective therapy, some patients fail. Proflox is a new alpha-pipelimic acid inhibitor that specifically inhibits gastric acid production.
![Page 39: Publishing your manuscript, Drenth (ppt, 362 kb)](https://reader033.vdocuments.us/reader033/viewer/2022060122/559667b01a28ab79128b45d2/html5/thumbnails/39.jpg)
Cover letter 2
• What you actually did– We performed a 24-week randomised clinical trial in
1256 subjects and show that Proflox is a very effective peptic ulcer healing drug, especially in the elderly.
• USP– This is a solid result and we would like to emphasize
that randomised drug trials are rare, if ever done, in peptic ulcer disease. In clinical practice peptic ulcer patients are randomly exposed to various drug regimens, all of them completely uncontrolled. We believe that it is in the interest of these patients and physicians alike that these results are disseminated. For these reasons we therefore sincerely hope that our manuscript merits publication in Gastroenterology

Cover letter 3
• Potential reviewers– Reviewers you pick give a better score than random
ones
• Obligatory stuff– The contents of this manuscript have not been
published elsewhere, and likewise the manuscript is not being submitted elsewhere. There is no potential conflict of interest for the individual authors. We would prefer to be contacted by e-mail. Thank you for your consideration.

Decision
• Revision requested– Accept with grace and humility– Respond with grace and humility
– Do provide a point to point review• Yeah…
– Mark your changes in the manuscript• Use the track mechanism in Word
– Do not be confrontational• It is a game and these are the rules

Rejection
• That is a bummer
• S… happens
• Sit down, sigh and move on• Do not write an angry response

Case reports are ‘bad’
• New ideas from case reports are not sustained on further research
• Contain "misleading elements" in clinical presentation
• More harm than good by emphasizing the bizarre
• Editors do not like it– Sloppy reviewing (nice observation)– Get few citations
• Few Journals publish case reports• Lowly status in the medical literature

How to case report?
• Why is this observation important? • What does it teach us? • Is it contrary to common thinking
– If so, explain Does it run counter to some particular cherished truth? (spell it out) this truth and explain the reader how and why it is contradicted.
• Does it strike the "prepared mind"? – Yeah, that we did not think of this
• Is it an unexpected association? – What was expected?
• Is it a rarity that could be missed?

Case report
“Case reports often introduce readers to new clinical techniques and allow them so see how
treatment can be made more efficient and effective”
“The writer (or narrator) should lay bare his or her thought process, as crisply and pointedly as
possible, because that it the only way to impress and strike a chord with the reader”

• Discussion – Emphasises unique or important aspects
• Here, we report a patient who developed acute pancreatitis after having taken TMP/SMX for many years as prophylaxis. Known causes of acute pancreatitis were ruled out. Discontinuation of TMP/SMX improved symptoms and we observed a relapse of acute pancreatitis within four days of restarting.
• Absence of a rash did not support hypersensitivity as a cause.
• Prolonged TMP/SMX use (20 yrs) can result in pancreatitis.
