2. [Systematic literature search in PubMed : A short introduction].
Blümle A, Lagrèze WA, Motschall E
In order to identify current (and relevant) evidence for a specific clinical
question within the unmanageable amount of information available, solid
skills in performing a systematic literature search are essential. An
efficient approach is to search a biomedical database containing relevant
literature citations of study reports. The best known database is MEDLINE,
which is searchable for free via the PubMed interface. In this article, we
explain step by step how to perform a systematic literature search via
PubMed by means of an example research question in the field of
ophthalmology. First, we demonstrate how to translate the clinical problem
into a well-framed and searchable research question, how to identify
relevant search terms and how to conduct a text word search and a search
with keywords in medical subject headings (MeSH) terms. We then show how to
limit the number of search results if the search yields too many irrelevant
hits and how to increase the number in the case of too few citations.
Finally, we summarize all essential principles that guide a literature
search via PubMed.

3. Modeling Keyword Search Strategy: Analysis of Pharmacovigilance
Specialists' Search of MedDRA Terms.
Marcilly R, Douze L, Bousquet C, Pelayo S
In the information retrieval task, searching and choosing keywords to form
the query is crucial. The present study analyzes and describes the keywords'
search strategy into a thesaurus in the field of pharmacovigilance. Two
ergonomics experts shadowed 22 pharmacovigilance specialists during their
daily work. They focus on the strategies for searching and choosing MedDRA
terms to build pharmacovigilance queries. Interviews of four
pharmacovigilance specialists completed the observations. Results highlight
that, for unusual or complex searches, pharmacovigilance specialists proceed
iteratively in three main phases: (i) preparation of a list of terms and of
evaluation criteria, (ii) exploration of the MedDRA hierarchy and choice of
a term, and (iii) evaluation of the results against the criteria. Overall,
the search and the choice of keywords within a thesaurus shares similarity
with the information retrieval task and is closely interwoven with the query
building process. Based on the results, the paper proposes design
specifications for new interfaces supporting the identification of MedDRA
terms so that pharmacovigilance reports searches achieve a good level of
expressiveness.

5. The Right to Write: Who 'Owns' the Case Report?
Agrawal A, Eiger D, Jain D, Allman R, Eiger G
In this Letter to the Editor, Agrawal et al. debate the conflicts that can
arise regarding the authorship of case reports. Like all other medical
journals, EJCRIM has zero tolerance for the willful undisclosed
re-submission of papers that have already been published elsewhere. However,
this may occasionally happen by accident, especially in large healthcare
institutions in which multiple teams of physicians may care for a patient
throughout their illness. EJCRIM endorses and recommends to all potential
authors the very sensible suggestions made by Agrawal et al. to avoid such
an error occurring. EJCRIM would also encourage authors to consider the
following: The first author should ensure that no one else involved in the
case has reported it or plans to report it. This is especially important for
physicians working in large healthcare centres, and/or for case reports of
patients who have been under investigation or treatment for prolonged
periods.On rare occasions EJCRIM will consider a case that has already been
published, provided that this is fully and explicitly disclosed, and there
is a clear reason why re-publication is justified. An example might be where
new information has come to light that significantly changes the conclusions
of the original report. As in all reports published by EJCRIM the decision
to publish will depend on the educational value, or learning points, of the
case.

6. A preliminary biopsychosocial analysis of online information on causes
of neck pain.
Neelapala YVR, Raja R, Bhandary A
OBJECTIVE: The aim of the present study was to analyse the freely available
online information on the causes of neck pain based on the biopsychosocial
model of pain.
METHODS: A preliminary biopsychosocial analysis tool was developed, after an
extensive literature review of the pathoanatomical and psychosocial
contributors for neck pain. The websites that commonly appeared after the
search term "causes of neck pain" in the first two pages of the search
engines (Google, Yahoo and Bing) were selected for the biopsychosocial
analysis. In addition, the websites were reviewed for Health on Net (HON)
certification.
RESULTS: Ten websites were analysed, of which eight were identified to
contain a predominant biomedical orientation, as they reported only the
pathoanatomical causes of neck pain. The remaining two websites were
determined to represent limited psychosocial information and described only
two psychological contributors to the neck pain.
CONCLUSIONS: The online information on the causes of neck pain appears to
contain limited biopsychosocial orientation. Further detailed analysis is
essential to obtain firm conclusions on the content validity of online
information on neck pain.

7. Seeking Formula for Misinformation Treatment in Public Health Crises:
The Effects of Corrective Information Type and Source.
van der Meer TGLA, Jin Y
An increasing lack of information truthfulness has become a fundamental
challenge to communications. Insights into how to debunk this type of
misinformation can especially be crucial for public health crises. To
identify corrective information strategies that increase awareness and
trigger actions during infectious disease outbreaks, an online experiment (N
= 700) was conducted, using a U.S. sample. After initial misinformation
exposure, participants' exposure to corrective information type (simple
rebuttal vs. factual elaboration) and source (government health agency vs.
news media vs. social peer) was varied, including a control group without
corrective information. Results show that, if corrective information is
present rather than absent, incorrect beliefs based on misinformation are
debunked and the exposure to factual elaboration, compared to simple
rebuttal, stimulates intentions to take protective actions. Moreover,
government agency and news media sources are found to be more successful in
improving belief accuracy compared to social peers. The observed mediating
role of crisis emotions reveals the mechanism underlying the effects of
corrective information. The findings contribute to misinformation research
by providing a formula for correcting the increasing spread of
misinformation in times of crisis.

8. Men's health on the web: an analysis of current resources.
Teh J, Wei J, Chiang G, Nzenza TC, Bolton D, Lawrentschuk N
INTRODUCTION: Men's health research covers a broad range of topics. Men and
women face different barriers to health, with men almost universally having
a lower life expectancy than women. Access to high-quality information on
men's health topics is potentially an important part of engaging men with
medical services. We aim to assess the quality of men's health resources
available on the internet across 4 developed countries using a tier-based
rating system as well as the World Health Organisation Health on the Net
(HON) standards.
METHODS: The Google search engine imbedded with the Health on the Net
toolbar was used to assess 357 websites across Australia, Canada, America
and United Kingdom using the search term 'men's health'. The websites were
further subdivided into 3 tiers by 2 independent investigators, with tier 1
websites defined as government or health organisation sponsored, tier 2
websites defined as being sponsored by health services such as private
clinics and insurance providers, and tier 3 websites being websites that did
not meet criteria for the first 2 tiers.
RESULTS: Overall, 28% of websites were rated as tier 1, 26% as tier 2 and
46% as tier 3. The HONcode accreditation was overall 39% of tier 1 websites.
The majority of websites reviewed were in the tier 3 category, and 35% of
overall websites being non-health or non-medically related.
DISCUSSION: The lack of 'relevant' and HONcode-accredited websites relating
to men's health should be appreciated by health care professionals.

9. Design of a generic, open platform for machine learning-assisted
indexing and clustering of articles in PubMed, a biomedical bibliographic
database.
Smalheiser NR, Cohen AM
Many investigators have carried out text mining of the biomedical literature
for a variety of purposes, ranging from the assignment of indexing terms to
the disambiguation of author names. A common approach is to define positive
and negative training examples, extract features from article metadata, and
employ machine learning algorithms. At present, each research group tackles
each problem from scratch, and in isolation of other projects, which causes
redundancy and great waste of effort. Here, we propose and describe the
design of a generic platform for biomedical text mining, which can serve as
a shared resource for machine learning projects, and can serve as a public
repository for their outputs. We will initially focus on a specific goal,
namely, classifying articles according to Publication Type, and emphasize
how feature sets can be made more powerful and robust through the use of
multiple, heterogeneous similarity measures as input to machine learning
models. We then discuss how the generic platform can be extended to include
a wide variety of other machine learning based goals and projects, and can
be used as a public platform for disseminating the results of NLP tools to
end-users as well.

10. Health Topics on Facebook Groups: Content Analysis of Posts in
Multiple Sclerosis Communities.
Della Rosa S, Sen F
BACKGROUND: Social network sites (SNSs) are being increasingly used to
exchange health information between patients and practitioners,
pharmaceutical companies, and research centers. Research contributions have
explored the contents of such exchanges discussed online. They have
categorized the topics discussed and explored the engagement levels of these
discussions.
OBJECTIVE: This research aimed at investigating the potential role of SNSs
in health care. Specifically it provides an information-clustering analysis
of the health information available on SNSs and develops a research design
that allows an investigation of this information in enhancing health care
research and delivery. In addition, this research aims at testing whether
SNSs are valid tools for sharing drug-related information by patients.
METHODS: This research is based on a specific chronic disease: multiple
sclerosis. We searched Facebook to identify and research the social media
groups related to this condition. The analysis was restricted to public
groups for privacy concerns. We created a database by downloading posts from
two main groups (in the English language). Subsequently, we performed a
content analysis and statistical analysis; this allowed us to explore the
differences between categories, their engagement levels, and the types of
posts shared. The mean level of engagement for each topic was analyzed using
a 1-way analysis of variance.
RESULTS: From a sample of 7029 posts, initial results showed that there were
8 information categories that resonated (percentage of times the topic
appears in our sample) with those who post on Facebook: information and
awareness (4923/7029, 70.04%), event advertising and petitions (365/7029,
5.19%), fundraising (354/7029, 5.04%), patient support (217/7029, 3.09%),
drug discussion (144/7029, 2.05%), clinical trials and research studies
(59/7029, 0.84%), product and drug advertising (48/7029, 0.68%), and other
(919/7029, 13.07%). Initial analysis showed that comments and likes (as
measures of engagement level) are the most frequent indicators and measures
of level of engagement. Our results show a high engagement level (in terms
of views, likes, comments, etc) for patient support and information and
awareness. In addition, although drug discussion had a low resonance, it had
an unexpected highly engagement level which we found worthy of further
exploration.
CONCLUSIONS: SNSs have become important tools for patients and health care
practitioners to share or seek information. We identified the type of
information shared and how the public reacted to it. Our research confirmed
that the topics discussed in social media related to specific diseases such
as multiple sclerosis are similar to the information categories observed by
other researchers. We unexpectedly found other categories such as drug
discussion. These and other results of our study enhance our understanding
of how content is disseminated and perceived within a specific disease-based
community. We concluded that this information has useful implications in the
design of prevention campaigns, educational programs, and chronic disease
management.

11. Disparity in online health information in pediatric vs. adult
surgical conditions.
Dee EC, Varady NH, Katz JN, Buchmiller TL
BACKGROUND: Although the quality of online health information (OHI) for
adult surgical conditions is well described, the availability of quality OHI
for pediatric surgical conditions, and the comparison to that of adult
surgical OHI, remains undefined.
METHODS: Medical and lay terms for 15 pediatric and 15 adult surgical
conditions were searched using Google in English. The Health on the Net
Foundation, a non-governmental OHI accreditation body, designates approval
for quality websites. We compared the role of patient population while
controlling for disease incidence (pediatric vs. adult), term complexity
(medical vs. lay), and order (earlier vs. later listing of websites) on
availability of quality OHI among the first 100 websites for each term.
RESULTS: Among the first 100 websites, the adjusted mean number of quality
websites was 11.80 for pediatric vs. 17.92 for adult medical search terms,
and 13.27 for pediatric vs. 18.20 for adult lay search terms (P < 0.05 for
all). Term complexity did not affect quality, and earlier appearing results
were more likely to be of high quality.
CONCLUSION: Availability of quality pediatric surgical OHI lags behind that
of adult surgical OHI, even when controlling for disease incidence. These
findings highlight the potential need for increased quality OHI in pediatric
surgery.

12. A Comparative Multimetric Assessment of English and Spanish Carpal
Tunnel Syndrome Materials.
Johnson AR, Doval AF, Granoff MD, Egeler SA, Bravo MG, Dowlatshahi AS, Lin
SJ, Lee BT
BACKGROUND: Spanish-speaking Hispanics living in the United States utilize
the internet as a primary means to obtain health information. Accurate,
accessible information is important for English speakers; however, it could
have even greater utility for Spanish speakers who have lower health
literacy levels. The aim of this study was to evaluate and compare online
English and Spanish carpal tunnel surgery materials provided by using a
multimetric approach.
MATERIALS AND METHODS: A web search using the English term "carpal tunnel
surgery" was performed. The first 10 institutional/organizational websites
that provided carpal tunnel surgery information in English and Spanish were
included. All relevant online materials were evaluated using the Patient
Education and Materials Assessment Tool (PEMAT), Cultural Sensitivity
Assessment Tool (CSAT), and Simplified Measure of Gobbledygook, Spanish
(SOL) to assess understandability and actionability, cultural sensitivity,
and readability, respectively.
RESULTS: There were no statistically significant differences in
understandability or actionability scores between Spanish and English
materials. Average cultural sensitivity scores for Spanish materials were
significantly lower than English materials (P = 0.015). The average reading
grade level of online English materials was greater than that for Spanish
materials (P = 0.011). Both mean values were above the recommended
sixth-grade reading level.
CONCLUSIONS: Online patient-directed information regarding carpal tunnel
surgery exceeded the recommended reading grade level for both English and
Spanish-speaking populations. Most Spanish materials were often direct
translations and were not contoured to the elevated literacy needs of this
demographic. Institutions must caution their authors to tailor their web
material in a way that is sensitive to their target population to optimize
understanding.
