In addition to the above explained (by Donay), just for participation´s sake:
"A partir da leitura e análise dos trabalhos, podem-se verificar tanto os aspectos gerais da doença quanto as diversas teorias sobre os fatores desencadeantes e aos tratamentos"From the reading of the
work/essay/writing/study...etc (done by the researchers/undergraduates of the Department...), one can verify/recognize both
broader/general aspects of the disease and
compare/choose from/opt for one (or more) of the triggering factors and  treatments.
It may be a sloppy translation, since I am not into the medical field, but if so, others will certainly improve it.
 Can be left out, it was just for the sake of variety and knowledge.
 Also: way of treatments, the wording is up to you.
