Características psicométricas dos instrumentos usados para avaliar a qualidade de vida na esclerose múltipla: uma revisão bibliográfica
Multiple sclerosis (MS) is the chronic neurological disease that most affects young adults; 80% of patients experience a transition towards persistent disability, hence the need to assess their quality of life (QoL). The aim of the study was to review studies that assess QoL in patients with multiple sclerosis, inquiring on the instruments used and their psychometric features. Articles published from 1997 through 2007 were searched for by means of key words "multiple sclerosis" and "quality of life" in databases Psycinfo, Psycarticles, Psycbooks, Psychology & Behavioral Science Collection, EJS E-Journal, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, Medline, and Academic Search Complete. From the 1,376 studies found, after abstract reading those that reported on instruments with poor psychometric properties and/or were little referred were excluded. A total of 461 articles were selected, of which 267 reported using generic instruments and 194, MS-specific ones. Among the 7 instruments reported by the studies as having good psychometric characteristics (2 generic, five MS-specific), the most used is the SF-36 (by 237 studies). All instruments have shown adequate psychometric properties and a high degree of reliability, hence may be used to assess QoL in subjects with multiple sclerosis both in clinic and research
Metabolomic profile and biological properties of sea lavender (Limonium algarvense Erben) plants cultivated with aquaculture wastewaters: implications for its use in herbal formulations and food additives
Water extracts from sea lavender (Limonium algarvense Erben) plants cultivated in greenhouse conditions and irrigated with freshwater and saline aquaculture effluents were evaluated for metabolomics by liquid chromatography-tandem high-resolution mass spectrometry (LC-HRMS/MS), and functional properties by in vitro and ex vivo methods. In vitro antioxidant methods included radical scavenging of 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS), ferric-reducing antioxidant power (FRAP), and copper and iron chelating assets. Flowers’ extracts had the highest compounds’ diversity (flavonoids and its derivatives) and strongest in vitro antioxidant activity. These extracts were further tested for ex vivo antioxidant properties by oxidative haemolysis inhibition (OxHLIA), lipid peroxidation inhibition by thiobarbituric acid reactive substances (TBARS) formation, and anti-melanogenic, anti-tyrosinase, anti-inflammation, and cytotoxicity. Extract from plants irrigated with 300 mM NaCl was the most active towards TBARS (IC50 = 81 µg/mL) and tyrosinase (IC50 = 873 µg/mL). In OxHLIA, the activity was similar for fresh- and saltwater-irrigated plants (300 mM NaCl; IC50 = 136 and 140 µg/mL, respectively). Samples had no anti-inflammatory and anti-melanogenic abilities and were not toxic. Our results suggest that sea lavender cultivated under saline conditions could provide a flavonoid-rich water extract with antioxidant and anti-tyrosinase properties with potential use as a food preservative or as a functional ingredient in herbal supplements.The authors acknowledge the Faculty of Pharmacy and Centre for Neurosciences and Cell Biology (University of Coimbra, Portugal) that kindly offered the murine RAW

Further evidence of possible therapeutic uses of Sambucus nigra L. extracts by the assessment of the In Vitro and In Vivo anti-inflammatory properties of Its PLGA and PCL-Based Nanoformulations
Sambucus nigra L. is widely used in traditional medicine with different applications. However, confirmative studies are strongly required. This study aimed to assess the biological activities of the S. nigra flower’s extract encapsulated into two different types of nanoparticles for optimizing its properties and producing further evidence of its potential therapeutic uses. Different nanoparticles (poly(lactide-co-glycolide, PLGA) and poly-Ɛ-caprolactone (PCL), both with oleic acid, were prepared by emulsification/solvent diffusion and solvent-displacement methods, respectively. Oleic acid was used as a capping agent. After the nanoparticles’ preparation, they were characterized and the biological activities were studied in terms of collagenase, in vitro and in vivo anti-inflammatory, and in vitro cell viability. Rutin and naringenin were found to be the major phenolic compounds in the studied extract. The encapsulation efficiency was higher than 76% and revealed to have an impact on the release of the extract, mainly for the PLGA. Moreover, biochemical and histopathological analyses confirmed that the extract-loaded PLGA-based nanoparticles displayed the highest anti-inflammatory activity. In addition to supporting the previously reported evidence of potential therapeutic uses of S. nigra, these results could draw the pharmaceutical industry’s interest to the novelty of the nanoproducts.Authors also gratefully acknowledge the Régiefrutas and Fundação para a Ciência e a Tecnologia

Growth performance, in vitro antioxidant properties and chemical composition of the halophyte Limonium algarvense Erben are strongly influenced by the irrigation salinity
Limonium algarvense Erben (sea lavender) is a halophyte species with potential to provide natural ingredients with in vitro antioxidant, anti-inflammatory, neuroprotective and antidiabetic properties. This study reports for the first time the 1) cultivation of sea lavender in greenhouse conditions under irrigation with freshwater (approx. 0 mM NaCl) and saline aquaculture wastewater (300 and 600 mM NaCl), and 2) the influence of the irrigation salinity on the plant performance (e.g growth, number of produced leaves and flowers), in vitro antioxidant properties [radical scavenging activity (DPPH and ABTS), ferric reducing antioxidant power (FRAP), metal chelating properties on copper (CCA) and iron (ICA)], toxicity (in vitro on three mammalian cell lines) and chemical composition (determined by LC-ESI-HRMS/MS). The freshwater-irrigated plants had better growth performance than those irrigated with saltwater. Extracts from wild plants, had the highest antioxidant activity, but those from cultivated ones kept high in vitro antioxidant properties and interesting chemical profile. The flowers' extracts of plants irrigated with 300 mM NaCl had the highest antioxidant activities against DPPH, whereas those from freshwater-irrigated plants were more active on ABTS, CCA and FRAP. Most of the extracts showed nil toxicity. The flowers' extracts displayed the highest diversity of compounds, mainly quercetin, apigenin, luteolin, naringenin and their glycoside derivatives. Moreover, their abundance varied with the irrigation salinity. These data indicate that sea lavender plants can be successfully cultivated in greenhouse conditions under fresh- and saltwater irrigation, maintaining interesting biological and chemical properties.Funding Agency

Nursing Students’ Perceptions on Healthcare-Associated Infection Control and Prevention Teaching and Learning Experience in Portugal
Healthcare-associated infections (HAI) are one of the major concerns worldwide, posing
significant challenges to healthcare professionals’ education and training. This study intended to
measure nursing students’ perceptions regarding their learning experiences on HAI prevention and
control. In the first phase of the study, a cross-sectional and descriptive study with a convenience
sample composed of undergraduate nursing students from Portugal, Spain, Poland, and Finland
was conducted to develop the InovSafeCare questionnaire. In the second phase, we applied the
InovSafeCare scale in a sample of nursing students from two Portuguese higher education institutions
to explore which factors impact nursing students’ adherence to HAI prevention and control measures
in clinical settings. In phase one, the InovSafeCare questionnaire was applied to 1326 students
internationally, with the instrument presenting adequate psychometric qualities with reliability
results in 14 dimensions. During phase two, the findings supported that Portuguese nursing students’
adherence to HAI prevention and control measures is influenced not only by the curricular offerings
and resources available in academic settings, but also by the standards conveyed by nursing tutors
during clinical placements. Our findings support the need for a dedicated curricular focus on HAI
prevention and control learning, not only through specific classroom modules, innovative resources,
and pedagogical approaches, but also through a complementary and coordinated liaison between
teachers and tutors in academic and clinical settings.info:eu-repo/semantics/publishedVersio
Nursing Students' Perceptions on Healthcare-Associated Infection Control and Prevention Teaching and Learning Experience: Development and Validation of a Scale in Four European Countries
Healthcare-associated infections are one of the major concerns worldwide. This
study presents the development and the validation process of the InovSafeCare
scale and aimed at identifying and measuring the ecosystem variables related to
healthcare-associated infection (HCAI) prevention and control practices in European
nurse students. Qualitative and quantitative approaches were used to (1) elaborate an
item pool related to the educational environment, the healthcare setting environment, and
the attitudes, beliefs, and performance of the nursing students regarding HCAI prevention
and control and (2) analyze psychometric properties of the scale using factor analysis.
The validated InovSafeCare scale was applied to undergraduate nursing students of
five European Higher Education Institutions. The partial least square structural equation
modeling (PLS-SEM) method with SMART-PLS3 software was used. The study sample
consists of 657 nursing students, who responded a self-report inventory. From the
analyzed data were identified 14 factors. The InovSafeCare scale reveals good validity
and reliability of the dimensions in different European countries.info:eu-repo/semantics/publishedVersio
