Multicenter survey on the use of device-assisted enteroscopy in Portugal
Background: Device-assisted enteroscopies (DAEs) are recent endoscopic techniques that enable direct endoscopic smallbowel
evaluation.
Objective: The objective of this article is to evaluate the implementation of DAEs in Portugal and assess the main indications,
diagnoses, diagnostic yield, therapeutic yield and complication rate.
Methods: We conducted a multicenter retrospective series using a national Web-based survey on behalf of the Portuguese
Small-Bowel Study Group. Participants were asked to fill out two online databases regarding procedural data, indications,
diagnoses, endoscopic therapy and complications using prospectively collected institutional data records.
Results: A total of eight centers were enrolled in the survey, corresponding to 1411 DAEs. The most frequent indications were
obscure gastrointestinal bleeding (OGIB), inflammatory bowel disease and small-bowel tumors. The pooled diagnostic yield
was 63%. A relation between the diagnostic yield and the indications was clear, with a diagnostic yield for OGIB of 69%
(p ÂĽ 0.02) with a 52% therapeutic yield. Complications occurred in 1.2%, with a major complication rate of 0.57%.
Perforations occurred in four patients (0.28%).
Conclusion: DAEs are safe and effective procedures, with complication rates of 1.2%, the most serious of which is perforation.
Most procedures are performed in the setting of OGIB. Diagnostic and therapeutic yields are dependent on the
indication, hence appropriate patient selection is crucial.info:eu-repo/semantics/publishedVersio
Small Bowel Enteroscopy - A Joint Clinical Guideline by the Spanish and Portuguese Small-Bowel Study Groups
The present evidence-based guidelines are focused on the use of device-assisted enteroscopy in the management of small-bowel diseases. A panel of experts selected by the Spanish and Portuguese small-bowel study groups reviewed the available evidence focusing on the main indications of this technique, its role in the management algorithm of each indication, and its diagnostic and therapeutic yield. A set of recommendations was issued accordingly.info:eu-repo/semantics/publishedVersio

Effect of ionic liquid anion and cation on the physico-chemical properties of poly(vinylidene fluoride)/ionic liquid blends
Poly(vinylidene fluoride), PVDF, has been blended with different ionic liquids (IL) in order to
evaluate the effect of the different IL anions and cations on the electroative -phase, thermal,
mechanical and electrical properties of the polymer blend. [C2MIM][Cl], [C6MIM][Cl],
[C10MIM][Cl], [C2MIM][NTf2], [C6MIM][NTf2], [C10MIM][NTf2] have been selected and
were introduced in the polymer at a weight percentage of 40 wt%. It was found that the
incorporation of ILs into the PVDF matrix leads to an increase of the -phase content due to
the strong electrostatic interactions between the dipolar moments of PVDF and the ILs.
Further, the incorporation of ILs into PVDF strongly decreases the elastic modulus and
increases the electrical conductivity of the blend with respect to the pure polymer matrix, all
these effects being accompanied by a modification of the crystallization kinetics, as indicated
by the modified spherulitic microstructure. Thus, novel PVDF/IL blends films with high
transparency, excellent antistatic properties, and highly polar crystal form fraction were
successfully achieved.This work was supported by FEDER through the COMPETE Program and by the Portuguese Foundation for Science and Technology (FCT) in the framework of the projects PEST-C/QUI/UIO686/2013, PEST-C/FIS/UI607/2014, UID/Multi/04551/2013 and PTDC/QUI-QUI/117340/2010.
