Biomedical research guidelines
Biomedical research: research involving human
subjects including research on identifiable human
material or identifiable data.
Medical research is only justified if there is a
reasonable likelihood that the populations in
which the research is carried out stand to benefit
from the results of the research.

Why EBM is a practical and correct tool?
A filter of
medical
knowledge
and scientific
data based on
predifined
rules.

Evidence-based Medicine (EBM)
Integrates pathophysiologic rationale, care-giver
experience, patient preferences with valid and
current clinical research evidence.
Must be able to critically review the research and
know if it applies to your patient-care problem.
“…the conscientious, explicit, and
judicious use of current best evidence
in making decisions about care of the
individual patients”.

“fudge factor”
Fattore di falsificazione
Sapendo, sulla base di speculazioni puramente
teoriche, quali devono essere i risultati cambiare il
valore dei parametri valutati finché non si ottengono i
risultati desiderati.

Nature 1988
Anti-IgE Ab obtained injecting human IgE in animals
Diluted anti IgE by a factor of 10 until no trace of
antibodies was detected
Added white cells derived from human blood
Obtained basophil degranulation!
High-dilution experiments a delusion
Maddox J Randi J Stewart WW
Nature 1988
“Repeating Dr Benveniste experiments we were surprised
that do not always work”
What to do for a scientific research:
Review international literature
Collect/ produce data
Analyse data
Control repeatability and reproducibility of methods
Draw conclusions
Impact Factors
The journal impact factor is a measure of the frequency
with which the "average article" in a journal has been cited
in a particular year.
The impact factor will help you evaluate a journal’s
relative importance, especially when you compare it to
others in the same field.
WARNING:
a higher I.F. means
a higher commercial value of the journal
