From the dried fruiting bodies of the mushroom Armillaria luteo-virens, a dimeric lectin with a molecular mass of 29.4 kDa has been isolated. The purification procedure involved (NH{sub 4}){sub 2}SO{sub 4} precipitation, ion exchange chromatography on DEAE-cellulose, CM-cellulose, and Q-Sepharose, and gel filtration by fast protein liquid chromatography on Superdex 75. The hemagglutinating activity of the lectin could not be inhibited by simple sugars but was inhibited by the polysaccharide inulin. The activity was stable up to 70 {sup o}C but was acid- and alkali-labile. Salts including FeCl{sub 3}, AlCl{sub 3}, and ZnCl{sub 2} inhibited the activity whereas MgCl{sub 2},more » MnCl{sub 2}, and CaCl{sub 2} did not. The lectin stimulated mitogenic response of mouse splenocytes with the maximal response achieved by 1 {mu}M lectin. Proliferation of tumor cells including MBL2 cells, HeLa cells, and L1210 cells was inhibited by the lectin with an IC{sub 5} of 2.5, 5, and 10 {mu}M, respectively. However, proliferation of HepG2 cells was not affected. The novel aspects of the isolated lectin include a novel N-terminal sequence, fair thermostability, acid stability, and alkali stability, together with potent mitogenic activity toward spleen cells and antiproliferative activity toward tumor cells.« less

Armillaria is a globally distributed mushroom-forming genus composed primarily of plant pathogens. Species in this genus are prolific producers of rhizomorphs, or vegetative structures, which, when found, are often associated with infection. Because of their importance as plant pathogens, understanding the evolutionary origins of this genus and how it gained a worldwide distribution is of interest. The first gasteroid fungus with close affinities to Armillaria-Guyanagaster necrorhizus-was described from the Neotropical rainforests of Guyana. In this study, we conducted phylogenetic analyses to fully resolve the relationship of G. necrorhizus with Armillaria. Data sets containing Guyanagaster from two collecting localities, along with a global sampling of 21 Armillaria species-including newly collected specimens from Guyana and Africa-at six loci (28S, EF1α, RPB2, TUB, actin-1 and gpd) were used. Three loci-28S, EF1α and RPB2-were analyzed in a partitioned nucleotide data set to infer divergence dates and ancestral range estimations for well-supported, monophyletic lineages. The six-locus phylogenetic analysis resolves Guyanagaster as the earliest diverging lineage in the armillarioid clade. The next lineage to diverge is that composed of species in Armillaria subgenus Desarmillaria. This subgenus is elevated to genus level to accommodate the exannulate mushroom-forming armillarioid species. The final lineage to diverge is that composed of annulate mushroom-forming armillarioid species, in what is now Armillaria sensu stricto. The molecular clock analysis and ancestral range estimation suggest the most recent common ancestor to the armillarioid lineage arose 51 million years ago in Eurasia. A new species, Guyanagaster lucianii sp. nov. from Guyana, is described. The armillarioid lineage evolved in Eurasia during the height of tropical rainforest expansion about 51 million years ago, a time marked by a warm and wet global climate. Species of Guyanagaster and

Armillaria possesses several intriguing characteristics that have inspired wide interest in understanding phylogenetic relationships within and among species of this genus. Nuclear ribosomal DNA sequence-based analyses of Armillaria provide only limited information for phylogenetic studies among widely divergent taxa. More recent studies have shown that translation elongation factor 1-α (tef1) sequences are highly informative for phylogenetic analysis of Armillaria species within diverse global regions. This study used Neighbor-net and coalescence-based Bayesian analyses to examine phylogenetic relationships of newly determined and existing tef1 sequences derived from diverse Armillaria species from across the Northern Hemisphere, with Southern Hemisphere Armillaria species included for reference. Based on the Bayesian analysis of tef1 sequences, Armillaria species from the Northern Hemisphere are generally contained within the following four superclades, which are named according to the specific epithet of the most frequently cited species within the superclade: (i) Socialis/Tabescens (exannulate) superclade including Eurasian A. ectypa, North American A. socialis (A. tabescens), and Eurasian A. socialis (A. tabescens) clades; (ii) Mellea superclade including undescribed annulate North American Armillaria sp. (Mexico) and four separate clades of A. mellea (Europe and Iran, eastern Asia, and two groups from North America); (iii) Gallica superclade including Armillaria Nag E (Japan), multiple clades of A. gallica (Asia and Europe), A. calvescens (eastern North America), A. cepistipes (North America), A. altimontana (western USA), A. nabsnona (North America and Japan), and at least two A. gallica clades (North America); and (iv) Solidipes/Ostoyae superclade including two A. solidipes/ostoyae clades (North America), A. gemina (eastern USA), A. solidipes/ostoyae (Eurasia), A. cepistipes (Europe and Japan), A. sinapina (North America and Japan), and A. borealis

Armillaria mellea, known as honey mushroom, has been used both as food and medicine. In this work, the ethanolic and hydromethanolic extracts from Armillaria mellea fruiting bodies were investigated for their phenolic content, antioxidant and antihyperglycemic effects (in vitro studies). The total phenolics were quantified using Folin-Ciocalteu assay. The antioxidant activity was evaluated by testing the free radical scavenging capacity, reducing power and ferrous ion chelating ability; in addition, the capacity to inhibit 15-lipoxygenase was also assessed. The antihyperglycemic activity was investigated by α-glucosidase assay. Total phenolic contents of 21.68 ± 0.06 and 5.70 ± 0.28 mg/g were determined in the hydromethanolic and ethanolic extracts, respectively. The hydromethanolic extract showed higher free radical scavenging and reducing abilities (EC50 = 452.6 ± 2.7, 140.57 ± 1.45 and 129.45 ± 0.98 μg/mL in DPPH, ABTS and reducing power assays, respectively). The ethanolic extract proved to be more efficient in the ferrous ion chelation, 15-lipoxygenase and α-glucosidase inhibition assays (EC55 = 67.93 ± 0.35, 290.93 ± 2.05 and 8.54 ± 0.06 μg/mL, respectively). Armillaria mellea extracts showed antioxidant and antihyperglycemic potential in in vitro models and therefore they are promising candidates for the development of dietary supplements and pharmaceutical products.

Agrobacterium tumefaciens-mediated transformation for investigation of somatic recombination in the fungal pathogen Armillaria mellea.

PubMed

Baumgartner, Kendra; Fujiyoshi, Phillip; Foster, Gary D; Bailey, Andy M

2010-12-01

Armillaria root disease is one of the most damaging timber and fruit tree diseases in the world. Despite its economic importance, many basic questions about the biology of the causal fungi, Armillaria spp., are unanswered. For example, Armillaria undergoes matings between diploid and haploid mycelia, which can result in a recombinant diploid without meiosis. Evidence of such somatic recombination in natural populations suggests that this reproductive mode may affect the pathogen's ecology. Investigations of the mechanisms and adaptive consequences of somatic recombination are, however, hampered by the lack of a method to reliably synthesize somatic recombinants. Here we report the first genetic transformation system for the genus Armillaria. We transformed A. mellea with selective markers for use in diploid-haploid matings to reliably synthesize somatic recombinants. This was accomplished with Agrobacterium tumefaciens carrying pBGgHg, which carries the hygromycin phosphotransferase gene (hph). hph was integrated into transformants, as evidenced by serial transfer to selective media, PCR, reverse transcription-PCR (RT-PCR), and Southern hybridization. Nuclear and mitochondrial markers were developed to genotype synthesized mycelia. In matings between a wild-type diploid and hygromycin-resistant haploids (transgenic), we identified recombinant, hygromycin-resistant diploids and, additionally, hygromycin-resistant triploids, all with the mitochondrial haplotype of the haploid partner. Our approach created no mycelium in which the haploid nucleus was replaced by the diploid nucleus, the typical outcome of diploid-haploid matings in Armillaria. This genetic transformation system, in combination with new markers to track chromosomal and cytoplasmic inheritance in A. mellea, will advance research aimed at characterizing the significance of somatic recombination in the ecology of this important fungus.

Fungal species of Armillaria, which can act as plant pathogens and/or symbionts of the Chinese traditional medicinal herb Gastrodia elata (“Tianma”), are ecologically and economically important and have consequently attracted the attention of mycologists. However, their taxonomy has been highly dependent on morphological characterization and mating tests. In this study, we phylogenetically analyzed Chinese Armillaria samples using the sequences of the internal transcribed spacer region, translation elongation factor-1 alpha gene and beta-tubulin gene. Our data revealed at least 15 phylogenetic lineages of Armillaria from China, of which seven were newly discovered and two were recorded from China for the first time. Fourteen Chinese biological species of Armillaria, which were previously defined based on mating tests, could be assigned to the 15 phylogenetic lineages identified herein. Seven of the 15 phylogenetic lineages were found to be disjunctively distributed in different continents of the Northern Hemisphere, while eight were revealed to be endemic to certain continents. In addition, we found that seven phylogenetic lineages of Armillaria were used for the cultivation of Tianma, only two of which had been recorded to be associated with Tianma previously. We also illustrated that G. elata f. glauca (“Brown Tianma”) and G. elata f. elata (“Red Tianma”), two cultivars of Tianma grown in different regions of China, form symbiotic relationships with different phylogenetic lineages of Armillaria. These findings should aid the development of Tianma cultivation in China. PMID:27138686

Production of anatoxin-a by cyanobacterial strains isolated from Portuguese fresh water systems.

2009-11-01

The occurrence of anatoxin-a in several freshwater systems in Portugal and its production by Portuguese cyanobacterial strains, after cultivation in laboratory, were studied. Surface water samples from 9 water bodies, for recreational and human consumption usage, were surveyed for anatoxin-a presence and for obtaining cultures of pure cyanobacterial strains. Anatoxin-a analysis was performed by high performance liquid chromatography (HPLC) with fluorescence detection (FLD) followed by Mass Spectrometry (MS) confirmation. No anatoxin-a was detected in all the natural water samples (limit of detection (LOD) = 25 ng l(-1)) but among the 22 isolated cyanobacterial strains, 13 could produce anatoxin-a in laboratory conditions (LOD = 3 ng g(-1) dw). This proportion of anatoxin-a producing strains (59.1%) in laboratory is discussed considering the hypothesis that anatoxin-a is a more frequent metabolite in cyanobacteria than it was thought before and making its occurrence in Portuguese freshwaters almost certain. Therefore, health and ecological risks caused by anatoxin-a in Portugal, should be seriously considered.

This work describes the first epidemiological survey of Burkholderia cepacia involved in pulmonary infections among the Portuguese population with cystic fibrosis (CF) who attended the major CF treatment Center in Lisbon at Sta. Maria Hospital from 1995 to the end of 1997. The characterization of the genomic relatedness of the isolates was based on the analysis of their ribopatterns (with EcoRI) followed by construction of a ribotype-based phylogenetic tree. This study was complemented with macrorestriction fragment analysis by pulsed-field gel electrophoresis. After optimization of the solid growth medium, we found that exopolysaccharide (EPS) production by B. cepacia CF isolates is not as rare a phenomenon as was thought before; indeed, 70% of the isolates examined were EPS producers.

Oleastro, Mónica; Rocha, Raquel; Vale, Filipa F

2017-08-01

The human gastric colonizer Helicobacter pylori is useful to track human migrations given the agreement between the bacterium phylogeographic distribution and human migrations. As Portugal was an African and Brazilian colonizer for over 400 years, we hypothesized that Portuguese isolates were likely genetically closer with those from countries colonized by Portuguese in the past. We aimed to characterize the population structure of several Portuguese-speaking countries, including Portugal, Brazil, Angola, and Cape Verde. We included strains isolated in Portugal from Portuguese and from former Portuguese colonies. These strains were typed by multilocus sequence typing (MLST) for seven housekeeping genes. We also retrieved from Multi Locus Sequence Typing Web site additional housekeeping gene sequences, namely from Angola and Brazil. We provided evidence that strains from Portuguese belong to hpEurope and that the introgression of hpEurope in non-European countries that speak Portuguese is low, except for Brazil and Cape Verde, where hpEurope accounted for one quarter and one half of the population, respectively. We found genetic similarity for all strains from Portuguese-speaking countries that belong to hpEurope population. Moreover, these strains showed a predominance of ancestral Europe 2 (AE2) over ancestral Europe 1 (AE1), followed by ancestral Africa 1. H. pylori is a useful marker even for relative recent human migration events and may become rapidly differentiated from founder populations. H. pylori from Portuguese-speaking countries assigned to hpEurope appears to be a hybrid population resulting from the admixture of AE1, AE2 and ancestral hpAfrica1. © 2017 John Wiley & Sons Ltd.

Genetic analysis reveals efficient sexual spore dispersal at a fine spatial scale in Armillaria ostoyae, the causal agent of root-rot disease in conifers.

PubMed

Dutech, Cyril; Labbé, Frédéric; Capdevielle, Xavier; Lung-Escarmant, Brigitte

Armillaria ostoyae (sometimes named Armillaria solidipes) is a fungal species causing root diseases in numerous coniferous forests of the northern hemisphere. The importance of sexual spores for the establishment of new disease centres remains unclear, particularly in the large maritime pine plantations of southwestern France. An analysis of the genetic diversity of a local fungal population distributed over 500 ha in this French forest showed genetic recombination between genotypes to be frequent, consistent with regular sexual reproduction within the population. The estimated spatial genetic structure displayed a significant pattern of isolation by distance, consistent with the dispersal of sexual spores mostly at the spatial scale studied. Using these genetic data, we inferred an effective density of reproductive individuals of 0.1-0.3 individuals/ha, and a second moment of parent-progeny dispersal distance of 130-800 m, compatible with the main models of fungal spore dispersal. These results contrast with those obtained for studies of A. ostoyae over larger spatial scales, suggesting that inferences about mean spore dispersal may be best performed at fine spatial scales (i.e. a few kilometres) for most fungal species.

ABSTRACT Armillaria mellea infects hundreds of plant species in natural and managed ecosystems throughout the Northern hemisphere. Previously reported nuclear genetic divergence between eastern and western U.S. isolates is consistent with the disjunct range of A. mellea in North America, which is restricted mainly to both coasts of the United States. We investigated patterns of population structure and genetic diversity of the eastern (northern and southern Appalachians, Ozarks, and western Great Lakes) and western (Berkeley, Los Angeles, St. Helena, and San Jose, CA) regions of the United States. In total, 156 diploid isolates were genotyped using 12 microsatellite loci. Absence of genetic differentiation within either eastern subpopulations (theta(ST) = -0.002, P = 0.5 ) or western subpopulations (theta(ST) = 0.004, P = 0.3 ) suggests that spore dispersal within each region is sufficient to prevent geographic differentiation. In contrast to the western United States, our finding of more than one genetic cluster of isolates within the eastern United States (K = 3), revealed by Bayesian assignment of multilocus genotypes in STRUCTURE and confirmed by genetic multivariate analyses, suggests that eastern subpopulations are derived from multiple founder sources. The existence of amplifiable and nonamplifiable loci and contrasting patterns of genetic diversity between the two regions demonstrate that there are two geographically isolated, divergent genetic pools of A. mellea in the United States.

Characterization of Armillaria spp. from peach orchards in the southeastern United States using fatty acid methyl ester profiling.

Cox, K D; Scherm, H; Riley, M B

2006-04-01

Limited information is available regarding the composition of cellular fatty acids in Armillaria and the extent to which fatty acid profiles can be used to characterize species in this genus. Fatty acid methyl ester (FAME) profiles generated from cultures of A. tabescens, A. mellea, and A. gallica consisted of 16-18 fatty acids ranging from 12-24 carbons in length, although some of these were present only in trace amounts. Across the three species, 9-cis,12-cis-octadecadienoic acid (9,12-C18:2), hexadecanoic acid (16:0), heneicosanoic acid (21:0), 9-cis-octadecenoic acid (9-C18:1), and 2-hydroxy-docosanoic acid (OH-22:0) were the most abundant fatty acids. FAME profiles from different thallus morphologies (mycelium, sclerotial crust, or rhizomorphs) displayed by cultures of A. gallica showed that thallus type had no significant effect on cellular fatty acid composition (P > 0.05), suggesting that FAME profiling is sufficiently robust for species differentiation despite potential differences in thallus morphology within and among species. The three Armillaria species included in this study could be distinguished from other lignicolous basidiomycete species commonly occurring on peach (Schizophyllum commune, Ganoderma lucidum, Stereum hirsutum, and Trametes versicolor) on the basis of FAME profiles using stepwise discriminant analysis (average squared canonical correlation = 0.953), whereby 9-C18:1, 9,12-C18:2, and 10-cis-hexadecenoic acid (10-C16:1) were the three strongest contributors. In a separate stepwise discriminant analysis, A. tabescens, A. mellea, and A. gallica were separated from one another based on their fatty acid profiles (average squared canonical correlation = 0.924), with 11-cis-octadecenoic acid (11-C18:1), 9-C18:1, and 2-hydroxy-hexadecanoic acid (OH-16:0) being most important for species separation. When fatty acids were extracted directly from mycelium dissected from naturally infected host tissue, the FAME-based discriminant functions

Portuguese Guitar

NASA Astrophysics Data System (ADS)

Inacio, Octavio

When referring to Portuguese traditional music, fado inevitably comes to mind. In this particular style of Portuguese music a singer is accompanied by two instruments: a classical guitar (more commonly known as viola) and a pear-shaped plucked chordophone, with six courses of double strings - the Portuguese guitar. The characteristic sonority of this instrument is a great part of what makes fado so distinguishable from any other style of traditional music in Europe. While from an ethnological and a musicological perspective this instrument has gained the attention of a handful of researchers (de Oliveira 2000; Cabral 1998), the scientific study of the vibroacoustic dynamics of these instruments is very recent. Fortunately, as with most other instruments, decades of refining craftsmanship have provided Portuguese guitars of excellent quality. Even if still unknown to the greater part of the musical world, the sonority, timbre and dynamical range of the Portuguese guitar continue to seduce many new listeners.

Section Flavi is one of the most significant sections in the genus Aspergillus. Taxonomy of this section currently depends on multivariate approaches, entailing phenotypic and molecular traits. This work aimed to identify isolates from section Flavi by combining various classic phenotypic and genotypic methods as well as the novel approach based on spectral analysis by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF ICMS) and to evaluate the discriminatory power of the various approaches in species identification.   Aspergillus section Flavi isolates obtained from Portuguese almonds were characterized in terms of macro- and micromorphology, mycotoxin pattern, calmodulin gene sequence and MALDI-TOF protein fingerprint spectra. For each approach, dendrograms were created and results were compared. All data sets divided the isolates into three groups, corresponding to taxa closely related to Aspergillus flavus, Aspergillus parasiticus and Aspergillus tamarii. In the A. flavus clade, molecular and spectral analyses were not able to resolve between aflatoxigenic and nonaflatoxigenic isolates. In the A. parasiticus cluster, two well-resolved clades corresponded to unidentified taxa, corresponding to those isolates with mycotoxin profile different from that expected for A. parasiticus. © 2011 The Authors.

A diverse surfactant, including the nonionic Tween 80 and Brij 30, the anionic sodium dodecyl sulphate, the cationic surfactant Tetradecyltrimethylammonium bromide, and biosurfactant Rhamnolipid were investigated under fluorine-enriched medium by Armilaria sp. F022. The cultures were performed at 25 °C in malt extract medium containing 1 % of surfactant and 5 mg/L of fluorene. The results showed among the tested surfactants, Tween-80 harvested the highest cell density and obtained the maximum specific growth rate. This due Tween-80 provide a suitable carbon source for fungi. Fluorane was also successfully eliminated (>95 %) from the cultures within 30 days in all flasks. During the experiment, laccase production was the highest among other enzymes and Armillaria sp. F022-enriched culture containing Non-ionic Tween 80 showed a significant result for laccase activity (1,945 U/L). The increased enzyme activity was resulted by the increased biodegradation activity as results of the addition of suitable surfactants. The biotransformation of fluorene was accelerated by Tween 80 at the concentration level of 10 mg/L. Fluorene was initially oxidized at C-2,3 positions resulting 9-fluorenone. Through oxidative decarboxylation, 9-fluorenone subjected to meta-cleavage to form salicylic acid. One metabolite detected in the end of experiment, was identified as catechol. Armillaria sp. F022 evidently posses efficient, high effective degrader and potential for further application on the enhanced bioremediation technologies for treating fluorene-contaminated soil.

Aflatoxin contamination of nuts is an increasing concern to the consumer's health. Portugal is a big producer of almonds, but there is no scientific knowledge on the safety of those nuts, in terms of mycotoxins. The aim of this paper was to study the incidence of aflatoxigenic fungi and aflatoxin contamination of 21 samples of Portuguese almonds, and its evolution throughout the various stages of production. All fungi belonging to Aspergillus section Flavi were identified and tested for their aflatoxigenic ability. Almond samples were tested for aflatoxin contamination by HPLC-fluorescence. In total, 352 fungi belonging to Aspergillus section Flavi were isolated from Portuguese almonds: 127 were identified as A. flavus (of which 28% produced aflatoxins B), 196 as typical or atypical A. parasiticus (all producing aflatoxins B and G), and 29 as A. tamarii (all nonaflatoxigenic). Aflatoxins were detected in only one sample at 4.97 μg/kg. PMID:22666128

A native promoter and inclusion of an intron is necessary for efficient expression of GFP or mRFP in Armillaria mellea

2016-01-01

Armillaria mellea is a significant pathogen that causes Armillaria root disease on numerous hosts in forests, gardens and agricultural environments worldwide. Using a yeast-adapted pCAMBIA0380 Agrobacterium vector, we have constructed a series of vectors for transformation of A. mellea, assembled using yeast-based recombination methods. These have been designed to allow easy exchange of promoters and inclusion of introns. The vectors were first tested by transformation into basidiomycete Clitopilus passeckerianus to ascertain vector functionality then used to transform A. mellea. We show that heterologous promoters from the basidiomycetes Agaricus bisporus and Phanerochaete chrysosporium that were used successfully to control the hygromycin resistance cassette were not able to support expression of mRFP or GFP in A. mellea. The endogenous A. mellea gpd promoter delivered efficient expression, and we show that inclusion of an intron was also required for transgene expression. GFP and mRFP expression was stable in mycelia and fluorescence was visible in transgenic fruiting bodies and GFP was detectable in planta. Use of these vectors has been successful in giving expression of the fluorescent proteins GFP and mRFP in A. mellea, providing an additional molecular tool for this pathogen. PMID:27384974

2003-11-01

The aim of this study was to evaluate the frequency of mutations of the P. jiroveci dihydropteroate synthase (DHPS) gene in an immunocompromised Portuguese population and to investigate the possible association between DHPS mutations and sulpha exposure. In the studied population, DHPS gene mutations were not significantly more frequent in patients exposed to sulpha drugs compared with patients not exposed (P=0.390). The results of this study suggest that DHPS gene mutations are frequent in the Portuguese immunocompromised population but do not seem associated with previous sulpha exposure. These results are consistent with the possibility of an incidental acquisition and transmission of P. jiroveci mutant types, either by person to person transmission or from an environmental source.

We examined the effects of a social and emotional learning program, Program Positive Attitude, on the social and emotional competencies and self-esteem of Portuguese elementary school students, from the twin perspectives of students and their teachers. Participants were 1237 fourth grade students from 37 schools in a Portuguese municipality, with a mean age of 9.2 years, of which 970 students (in 86 classes) participated in the program and 267 students (in 21 classes) served as a comparison group. Students and their teachers completed questionnaires prior to and following the intervention. We used multilevel linear modeling with a repeated measures design to evaluate the effectiveness of the program. Both students and their teachers reported significant intervention gains in self-control and social awareness. Students' in the intervention group also identified reductions in social isolation and improvements in self-esteem, and their teachers reported decreases in their students' social anxiety. An analysis by gender revealed that only girls showed increases in self-esteem, and only boys reported reduced social isolation. These findings support the effectiveness of the program.

2014-03-01

The EQ-5D is a widely used preference-based measure. Normative data can be used as references to analyze the effects of healthcare, determine the burden of disease and enable regional or country comparisons. Population norms for the EQ-5D exist for other countries but have not been previously published for Portugal. The purpose of this study was to derive EQ-5D Portuguese population norms. The EQ-5D was applied by phone interview to a random sample of the Portuguese general population (n = 1,500) stratified by age, gender and region. The Portuguese value set was used to derive the EQ-5D index. Mean values were computed by gender and age groups, marital status, educational attainment, region and other variables to obtain the EQ-5D Portuguese norms. Health status declines with advancing age, and women reported worse health status than men. These results are similar to other EQ-5D population health studies. This study provides Portuguese population health-related quality of life data measured by the EQ-5D that can be used as population norms. These norms can be used to inform Portuguese policy makers, health care professionals and researchers in issues related to health care policy and planning and quantification of treatment effects on health status.

During their biosynthesis, some members of the melleolide family of compounds undergo monochlorination of the aromatic moiety, whose biochemical and genetic basis was not known previously. This first study on basidiomycete halogenases presents the biochemical in vitro characterization of five flavin-dependent A. mellea enzymes (ArmH1 to ArmH5) that were heterologously produced in Escherichia coli. We demonstrate that all five enzymes transfer a single chlorine atom to the melleolide backbone. A 5-fold, secured biosynthetic step during natural product assembly is unprecedented. Typically, flavin-dependent halogenases are categorized into enzymes acting on free compounds as opposed to those requiring a carrier-protein-bound acceptor substrate. The enzymes characterized in this study clearly turned over free substrates. Phylogenetic clades of halogenases suggest that all fungal enzymes share an ancestor and reflect a clear divergence between ascomycetes and basidiomycetes. PMID:26655762

Youth problem gambling is viewed as an emergent public health issue in many countries, and is also an emerging area of public concern in Portugal. However, there is currently no Portuguese instrument that focuses specifically on the measurement of problem gambling among young people. Consequently, the present study aimed to validate the DSM-IV-MR-J for use among Portuguese adolescents and to examine its' psychometric properties. A cross-cultural adaption of this instrument to the Portuguese language was performed using the translation and back translation method. The final version of the instrument was administered to 753 Portuguese high school and first year college students. The findings revealed an acceptable internal reliability and replicated the one-factor structure of this scale. Based on these findings, the Portuguese DSM-IV-MR-J appears to be a valid and reliable instrument, and provides a much needed psychometric tool for the development of more research on youth gambling in Portugal.

Portugal is an important player in the European fashion industry. The Portuguese footwear industry, “low-tech” and traditional industry, dominated by SMEs and located in two main clusters, is a success case in the Portuguese economy. After a long period of decline until 2009, the footwear companies prepared new strategies that made big changes in the image and performance achieved. Since 2009, exports have increased more than 55% and the Portuguese footwear has grown in almost all the most important foreign markets. The competitive strategies followed by the Portuguese footwear companies are different and they can be clearly identified according Porter’s three generic competitive strategies: cost leadership, differentiation and focus strategy. This paper had analysed seven Portuguese footwear companies (seven cases, case study strategy) and the results obtained shows how important is to have the right approach to the markets, according the internal and external resources that each firm has available. The footwear clusters in Portugal and the sectorial organizations are also very important in this competitive performance achieved by the companies. Last years the Portuguese governments recognize this increasing importance of the fashion industries and prepared several programs to promote these industries in Europe and other continents.

According to the organization model of the Portuguese Electric System, there is the coexistence of two subsystems with different characteristics: the Public Electric System, which has public service obligations and the Independent Electric System which does not have such obligations, and part of it obeys a market logic. Nowadays, the Public Electric System is the main component of the electric sector, however there are reasons to believe that the Independent System can increase its participation. The 1995 Portuguese legislation established the existence of an independent structure to regulate the electric sector: the Electric Sector Regulatory Entity. In this paper, themore » organization of this entity is described, as well as its objectives and main powers.« less

Review of Portuguese Cistercian Monastic Heritage

Martins, Ana M. T.

2017-10-01

This paper aims to present a contribution to the history of the reform and renewal in the Portuguese Cistercian monasteries throughout almost nine centuries of cultural and architectural history in this Country. The Cistercian Order played a remarkable role in the affirmation of Portugal (1143) and had unquestionable position, since the medieval period, in the construction of a significant part of the Portuguese culture. The reform of many Monasteries came with the Autonomous Congregation of Alcobaça (1567). In fact, the Portuguese Cistercian Monasteries absorbed the regional ways of construction with masonry (granite in the north and limestone in the south) but it is without a doubt in its architecture that change and renewal can be found as strength and a tool for achieving a status of cultural landmarks. The renewal and reform in the Portuguese Cistercian Monasteries was not restricted to the styles in vogue but also was related to the physical expansion of the monasteries. This could be achieved by adding new aisles and cloisters like in Alcobaça or Salzedas Monasteries. Though there are cases of unconventional renewals and reformations such as the existence of two churches in the Monastery of Salzedas and the example of the open air Museum of the Monastery of S. João de Tarouca were can be found the former medieval monastery, as a result of new archaeological research and a prospective hypothesis of its volumetric layout, in between the walls of the 17th century dormitories and the Church. This continuous architectonic renewal is still being carried out in the 21st century either by the Portuguese Government, through several heritage institutes since the 20th century, or a few individuals on their one.The history of the Portuguese Cistercian Monasteries blends itself with the history of Portugal as the continuous architectonic renewals and reforms were also a result of nine centuries of events and changes in this Country.

Aiming at increasing the knowledge on marine cyanobacteria from temperate regions, we previously isolated and characterized 60 strains from the Portuguese foreshore and evaluate their potential to produce secondary metabolites. About 15% of the obtained 16S rRNA gene sequences showed less than 97% similarity to sequences in the databases revealing novel biodiversity. Herein, seven of these strains were extensively characterized and their classification was re-evaluated. The present study led to the proposal of five new taxa, three genera (Geminobacterium, Lusitaniella, and Calenema) and two species (Hyella patelloides and Jaaginema litorale). Geminobacterium atlanticum LEGE 07459 is a chroococcalean that shares morphological characteristics with other unicellular cyanobacterial genera but has a distinct phylogenetic position and particular ultrastructural features. The description of the Pleurocapsales Hyella patelloides LEGE 07179 includes novel molecular data for members of this genus. The filamentous isolates of Lusitaniella coriacea - LEGE 07167, 07157 and 06111 - constitute a very distinct lineage, and seem to be ubiquitous on the Portuguese coast. Jaaginema litorale LEGE 07176 has distinct characteristics compared to their marine counterparts, and our analysis indicates that this genus is polyphyletic. The Synechococcales Calenema singularis possess wider trichomes than Leptolyngbya, and its phylogenetic position reinforces the establishment of this new genus. Copyright © 2017 Elsevier Inc.

The nosocomial prevalence of methicillin resistant Staphylococcus aureus (MRSA) in Portugal remains one of the highest in Europe and is currently around 50%. Transmission of S. aureus, including MRSA, occurs principally by direct human-to-human skin contact. However, S. aureus can survive for long periods on inanimate objects, which may represent an important reservoir for dissemination as well. Between May 2009 and February 2010, handrails of 85 public urban buses circulating in Oporto, Portugal, were screened for the occurrence of MRSA. Twenty-two (26%) buses showed MRSA contamination. The molecular characterization of a total of 55 MRSA, by pulsed-field gel electrophoresis (PFGE), staphylococcal cassette chromosome (SCC) mec typing, spa typing, and multilocus sequence typing (MLST), clustered the isolates into three clonal types. However, the overwhelming majority (n = 50; 91%) of the isolates belonged to a single clone (PFGE A, spa types t747, t032, t025 or t020, ST22, SCCmec type IVh) that exhibits the characteristics of the pandemic EMRSA-15, currently the major lineage circulating in Portuguese hospitals, namely in the Oporto region. Two additional clones were found but in much lower numbers: (i) PFGE B, ST5, spa type t002, SCCmec IVa (n = 3), and (ii) PFGE C, spa type t008, ST8, SCCmec IVa (n = 2). None of the 55 isolates was PVL positive. Public buses in Oporto seem to be an important reservoir of MRSA of nosocomial origin, providing evidence that the major hospital-associated MRSA clone in Portugal is escaping from the primary ecological niche of hospitals to the community environment. Infection control measures are urgently warranted to limit the spread of EMRSA-15 to the general population and future studies are required to assess the eventual increase of MRSA in the Portuguese community, which so far remains low.

This study explored American and Portuguese elementary teachers' preferences in planning for literacy instruction using the Language Arts Activity Grid (LAAG; Cunningham, Zibulsky, Stanovich, & Stanovich, 2009), on which teachers described their preferred instructional activities for a hypothetical 2-h language arts block. Portuguese teachers (N = 186) completed Portuguese versions of a background questionnaire and LAAG electronically, in Survey Monkey; American teachers (N = 102) completed identical English measures using paper and pencil. Results showed that teachers in both groups usually addressed comprehension and reading fluency on their LAAGs and that they also allocated the most time to these two areas. However, American teachers were more likely to include teacher-directed fluency activities, whereas Portuguese teachers were more likely to include fluency activities that were not teacher directed. Significantly more American than Portuguese teachers addressed phonics in their planning, whereas significantly more Portuguese than American teachers addressed writing processes such as revision. Both groups of educators demonstrated large variability in planning, with many teachers omitting important components of literacy identified by researchers, for writing as well as reading. The study highlights the importance of providing teachers with comprehensive, research-based core literacy curricula as well as professional development on key components of literacy. Study findings also suggest significant relationships between orthographic transparency and teachers' instructional planning.

Armillaria mellea is a famous traditional Chinese medicinal and edible fungus. In this study, we purified a water-soluble polysaccharide (AMP) from the fruiting bodies of this fungus. AMP contained 94.8% carbohydrate, 2.3% uronic acid and 0.5% protein. Its molecular weight was determined as 4.6 × 10⁵ Da, as determined by high-performance gel-permeation chromatography (HPGPC). Gas chromatography (GC) analysis indicated that AMP was mainly composed of d-glucose. In vitro assay, AMP exhibited a potent tumor growth inhibitory effect on A549 cells, and induced cell cycle disruption in the G0/G1 phase, accompanied by an increment of apoptotic cells. Furthermore, AMP induced the disruption of mitochondrial membrane potential, thus leading to cytochrome c release from mitochondria and activation of caspase-3 and -9. Taken together, our results demonstrate that AMP possesses strong antitumor activities through the mitochondria dependent pathway and activation of caspase cascade through cytochrome c release.

The first documents mentioning Jewish people in Iberia are from the Visigothic period. It was also in this period that the first documented anti-Judaic persecution took place. Other episodes of persecution would happen again and again during the long troubled history of the Jewish people in Iberia and culminated with the Decrees of Expulsion and the establishment of the Inquisition: some Jews converted to Catholicism while others resisted and were forcedly baptized, becoming the first Iberian Crypto-Jews. In the 18th century the official discrimination and persecution carried out by the Inquisition ended and several Jewish communities emerged in Portugal. From a populational genetics point of view, the worldwide Diaspora of contemporary Jewish communities has been intensely studied. Nevertheless, very little information is available concerning Sephardic and Iberian Crypto-Jewish descendants. Data from the Iberian Peninsula, the original geographic source of Sephardic Jews, is limited to two populations in Portugal, Belmonte, and Bragança district, and the Chueta community from Mallorca. Belmonte was the first Jewish community studied for uniparental markers. The construction of a reference model for the history of the Portuguese Jewish communities, in which the genetic and classical historical data interplay dynamically, is still ongoing. Recently an enlarged sample covering a wide region in the Northeast Portugal was undertaken, allowing the genetic profiling of male and female lineages. A Jewish specific shared female lineage (HV0b) was detected between the community of Belmonte and Bragança. In contrast to what was previously described as a hallmark of the Portuguese Jews, an unexpectedly high polymorphism of lineages was found in Bragança, showing a surprising resistance to the erosion of genetic diversity typical of small-sized isolate populations, as well as signs of admixture with the Portuguese host population.

Portuguese propolis disturbs glycolytic metabolism of human colorectal cancer in vitro

PubMed Central

2013-01-01

Background Propolis is a resin collected by bees from plant buds and exudates, which is further processed through the activity of bee enzymes. Propolis has been shown to possess many biological and pharmacological properties, such as antimicrobial, antioxidant, immunostimulant and antitumor activities. Due to this bioactivity profile, this resin can become an alternative, economic and safe source of natural bioactive compounds. Antitumor action has been reported in vitro and in vivo for propolis extracts or its isolated compounds; however, Portuguese propolis has been little explored. The aim of this work was to evaluate the in vitro antitumor activity of Portuguese propolis on the human colon carcinoma cell line HCT-15, assessing the effect of different fractions (hexane, chloroform and ethanol residual) of a propolis ethanol extract on cell viability, proliferation, metabolism and death. Methods Propolis from Angra do Heroísmo (Azores) was extracted with ethanol and sequentially fractionated in solvents with increasing polarity, n-hexane and chloroform. To assess cell viability, cell proliferation and cell death, Sulforhodamine B, BrDU incorporation assay and Anexin V/Propidium iodide were used, respectively. Glycolytic metabolism was estimated using specific kits. Results All propolis samples exhibited a cytotoxic effect against tumor cells, in a dose- and time-dependent way. Chloroform fraction, the most enriched in phenolic compounds, appears to be the most active, both in terms of inhibition of viability and cell death. Data also show that this cytotoxicity involves disturbance in tumor cell glycolytic metabolism, seen by a decrease in glucose consumption and lactate production. Conclusion Our results show that Portuguese propolis from Angra do Heroísmo (Azores) can be a potential therapeutic agent against human colorectal cancer. PMID:23870175

As adolescent pregnancy and sexually transmitted infections (STIs) are major sources of morbidity, preventing them is an important health goal for Portuguese society. To review data on the knowledge, attitudes and statistics on sexual and reproductive health. A systematic review was conducted including peer-reviewed articles addressing issues influencing the sexuality of Portuguese adolescents (aged 13 to 19), published up to 2011 and conducted in any type of setting. After crossing-cleaning the reference list, 33 articles were included. The rate of sexual activity by Portuguese adolescents is high (44%-95%), but there has been an increase in the age of intercourse debut (currently 15.6 years). Early commencement of sexual intercourse is associated with smoking and regular alcohol consumption. Condoms are the most frequently chosen contraceptive method for first (76%-96%) and subsequent (52%-69%) sexual encounters. The perception of a double standard in sex still exists in teenage culture for both genders and influence behavior. There are significant differences between migrant and native adolescents: African adolescents initiate sexual intercourse at earlier ages and are more likely to have unprotected sex. Only one-third of Portuguese teenagers have ever visited a health facility to seek counseling concerning contraception or STIs, and less than half have ever attended classes on reproductive health. Very few (12%) have knowledge about Chlamydia trachomatis infection. The prevalence of STIs in Portuguese youth is unknown. The adolescent fertility rate is still high (14.7 births per 1000 females aged 15-19 years), but it, as well as the rate of abortion, is steadily decreasing. There is still a long way to go towards promoting a resourceful young population. Citizens and institutions must focus on increasing both the competence of youths and external supports. Information must be provided systematically and health services must have greater accessibility. Studies

Marine cyanobacteria, notably those from tropical regions, are a rich source of bioactive secondary metabolites. Tropical marine cyanobacteria often grow to high densities in the environment, allowing direct isolation of many secondary metabolites from field-collected material. However, in temperate environments culturing is usually required to produce enough biomass for investigations of their chemical constituents. In this work, we cultured a selection of novel and diverse cyanobacteria isolated from the Portuguese coast, and tested their organic extracts in a series of ecologically-relevant bioassays. The majority of the extracts showed activity in at least one of the bioassays, all of which were run in very small scale. Phylogenetically related isolates exhibited different activity profiles, highlighting the value of microdiversity for bioprospection studies. Furthermore, LC-MS analyses of selected active extracts suggested the presence of previously unidentified secondary metabolites. Overall, the screening strategy employed here, in which previously untapped cyanobacterial diversity was combined with multiple bioassays, proved to be a successful strategy and allowed the selection of several strains for further investigations based on their bioactivity profiles.

The use of adequate assessment tools in health care is crucial for the management of care. The lack of specific tools in Portugal for assessing the performance of children who use cochlear implants motivated the translation and adaptation of the EARS (Evaluation of Auditory Responses to Speech) test battery into European Portuguese. This test battery is today one of the most commonly used by (re)habilitation teams of deaf children who use cochlear implants worldwide. The goal to be achieved with the validation of EARS was to provide (re)habilitation teams an instrument that enables: (i) monitoring the progress of individual (re)habilitation, (ii) managing a (re)habilitation program according to objective results, comparable between different (re)habilitation teams, (iii) obtaining data that can be compared with the results of international teams, and (iv) improving engagement and motivation of the family and other professionals from local teams. For the test battery translation and adaptation process, the adopted procedures were the following: (i) translation of the English version into European Portuguese by a professional translator, (ii) revision of the translation performed by an expert panel, including doctors, speech-language pathologists and audiologists, (iii) adaptation of the test stimuli by the team's speechlanguage pathologist, and (iv) further review by the expert panel. For each of the tests that belong to the EARS battery, the introduced adaptations and adjustments are presented, combining the characteristics and objectives of the original tests with the linguistic and cultural specificities of the Portuguese population. The difficulties that have been encountered during the translation and adaptation process and the adopted solutions are discussed. Comparisons are made with other versions of the EARS battery. We defend that the translation and the adaptation process followed for the EARS test battery into European Portuguese was correctly conducted

Bacteriocin B231 produced by Lactobacillus pentosus, isolated from an artisanal raw cow's milk protected designation of origin Portuguese cheese, is a small protein with an apparent relative mass of about 5 kDa and active against a large number of Listeria monocytogenes wild-type strains, Listeria ivanovii and Listeria innocua. Bacteriocin B231 production is highly dependent on the type of the culture media used for growth of Lact. pentosus B231. Replacement of glucose with maltose yielded the highest bacteriocin production from eight different carbon sources. Similar results were recorded in the presence of combination of glucose and maltose or galactose. Production of bacteriocin B231 reached maximal levels of 800 AU/ml during the stationary phase of growth of Lact. pentosus B231 in MRS broth at 30 °C. Bacteriocin B231 (in cell-free supernatant) was sensitive to treatment with trypsin and proteinase K, but not affected by the thermal treatment in range of 55-121 °C, or freezing (-20 °C). Bacteriocin production and inhibitory spectrum were evaluated. Gene encoding plantaricin S has been detected in the genomic DNA. Virulence potential and safety of Lact. pentosus B231 were assessed by PCR targeted the genes gelE, hyl, asa1, esp, cylA, efaA, ace, vanA, vanB, hdc1, hdc2, tdc and odc. The Lact. pentosus B231 strains harbored plantaricin S gene, while the occurrence of virulence, antibiotic resistance and biogenic amine genes was limited to cytolysin, hyaluronidase, aggregation substance, adhesion of collagen protein, gelatinase, tyrosine decarboxylase and vancomycin B genes.

Do Portuguese and UK health state values differ across valuation methods?

PubMed

Ferreira, Lara N; Ferreira, Pedro L; Rowen, Donna; Brazier, John E

2011-05-01

There has been an increasing interest in developing country-specific preference weights for widely used measures of health-related quality of life. The valuation of health states has usually been done using cardinal preference elicitation techniques of standard gamble (SG) or time trade-off (TTO). Yet there is increasing interest in the use of ordinal methods to elicit health state utility values as an alternative to the more conventional cardinal techniques.This raises the issue of firstly whether ordinal and cardinal methods of preference elicitation provide similar results and secondly whether this relationship is robust across different valuation studies and different populations. This study examines SG and rank preference weights for the SF-6D derived from samples of the UK and Portuguese general population. The preference weights for the Portuguese sample (n = 140) using rank data are estimated here with 810 health state valuations. The study further examines whether the use of these different preference weights has an impact when comparing the health of different age and severity groups in the Portuguese working population (n = 2,459). The rank model performed well across the majority of measures of goodness of fit used. The preference weights for the Portuguese sample using rank data are systematically lower than the UK weights for physical functioning and pain. Yet our results suggest higher similarity between preference weights derived using rank data than using standard gamble across the UK and Portuguese samples. Our results further suggest that the SF-6D values for a sample of the Portuguese working-age population and differences across groups are affected by the use of different preference weights. We suggest that the use of a Portuguese SF-6D weighting system is preferred for studies aiming to reflect the health state preferences of the Portuguese population.

2017-01-01

Armillaria mellea, an edible fungus, exhibits various pharmacological activities, including antioxidant and antiapoptotic properties. However, the effects of A. mellea on Alzheimer's disease (AD) have not been systemically reported. The present study aimed to explore the protective effects of mycelium polysaccharides (AMPS) obtained from A. mellea, especially AMPSc via 70% ethanol precipitation in a L-glutamic acid- (L-Glu-) induced HT22 cell apoptosis model and an AlCl3 plus D-galactose- (D-gal-) induced AD mouse model. AMPSc significantly enhanced cell viability, suppressed nuclear apoptosis, inhibited intracellular reactive oxygen species accumulation, prevented caspase-3 activation, and restored mitochondrial membrane potential (MMP). In AD mice, AMPSc enhanced horizontal movements in an autonomic activity test, improved endurance times in a rotarod test, and decreased escape latency time in a water maze test. Furthermore, AMPSc reduced the apoptosis rate, amyloid beta (Aβ) deposition, oxidative damage, and p-Tau aggregations in the AD mouse hippocampus. The central cholinergic system functions in AD mice improved after a 4-week course of AMPSc administration, as indicated by enhanced acetylcholine (Ach) and choline acetyltransferase (ChAT) concentrations, and reduced acetylcholine esterase (AchE) levels in serum and hypothalamus. Our findings provide experimental evidence suggesting A. mellea as a neuroprotective candidate for treating or preventing neurodegenerative diseases. PMID:29081887

We describe the corpus development, the specific characteristics on the internet site and database for user access. We also perform distributional analyses of the corpus and comparisons to other current databases. Our main objective was to provide a large, reliable, and useful word-based corpus with a dynamic, easy-to-use, and intuitive interface with free internet access for word and word-criteria searches. We used the Núcleo Interinstitucional de Linguística Computacional’s corpus as the basic data source and developed the Brazilian Portuguese Lexicon by deriving and adding metalinguistic and psycholinguistic information about Brazilian Portuguese words. We obtained a final corpus with more than 30 million word tokens, 215 thousand word types and 25 categories of information about each word. This corpus was made available on the internet via a free-access site with two search engines: a simple search and a complex search. The simple engine basically searches for a list of words, while the complex engine accepts all types of criteria in the corpus categories. The output result presents all entries found in the corpus with the criteria specified in the input search and can be downloaded as a.csv file. We created a module in the results that delivers basic statistics about each search. The Brazilian Portuguese Lexicon also provides a pseudoword engine and specific tools for linguistic and statistical analysis. Therefore, the Brazilian Portuguese Lexicon is a convenient instrument for stimulus search, selection, control, and manipulation in psycholinguistic experiments, as also it is a powerful database for computational linguistics research and language modeling related to lexicon distribution, functioning, and behavior.

Our main objective was to provide a large, reliable, and useful word-based corpus with a dynamic, easy-to-use, and intuitive interface with free internet access for word and word-criteria searches. We used the Núcleo Interinstitucional de Linguística Computacional's corpus as the basic data source and developed the Brazilian Portuguese Lexicon by deriving and adding metalinguistic and psycholinguistic information about Brazilian Portuguese words. We obtained a final corpus with more than 30 million word tokens, 215 thousand word types and 25 categories of information about each word. This corpus was made available on the internet via a free-access site with two search engines: a simple search and a complex search. The simple engine basically searches for a list of words, while the complex engine accepts all types of criteria in the corpus categories. The output result presents all entries found in the corpus with the criteria specified in the input search and can be downloaded as a.csv file. We created a module in the results that delivers basic statistics about each search. The Brazilian Portuguese Lexicon also provides a pseudoword engine and specific tools for linguistic and statistical analysis. Therefore, the Brazilian Portuguese Lexicon is a convenient instrument for stimulus search, selection, control, and manipulation in psycholinguistic experiments, as also it is a powerful database for computational linguistics research and language modeling related to lexicon distribution, functioning, and behavior.

The Portuguese Local Warming Website (http://portaldoclima.pt) has been developed in order to support the society in Portugal in preparing for the adaptation to the ongoing and future effects of climate change. The climate portal provides systematic and easy access to authoritative scientific data ready to be used by a vast and diverse user community from different public and private sectors, key players and decision makers, but also to high school students, contributing to the increase in knowledge and awareness on climate change topics. A comprehensive set of regional climate variables and indicators are computed, explained and graphically presented. Variables and indicators were built in agreement with identified needs after consultation of the relevant social partners from different sectors, including agriculture, water resources, health, environment and energy and also in direct cooperation with the Portuguese National Strategy for Climate Change Adaptation (ENAAC) group. The visual interface allows the user to dynamically interact, explore, quickly analyze and compare, but also to download and import the data and graphics. The climate variables and indicators are computed from state-of-the-art regional climate model (RCM) simulations (e.g., CORDEX project), at high space-temporal detail, allowing to push the limits of the projections down to local administrative regions (NUTS3) and monthly or seasonal periods, promoting local adaptation strategies. The portal provides both historical data (observed and modelled for the 1971-2000 period) and future climate projections for different scenarios (modelled for the 2011-2100 period). A large effort was undertaken in order to quantify the impacts of the risk of extreme events, such as heavy rain and flooding, droughts, heat and cold waves, and fires. Furthermore the different climate scenarios and the ensemble of RCM models, with high temporal (daily) and spatial (~11km) detail, is taken advantage in order to

Portuguese immigrant families: the impact of acculturation.

Morrison, Marie; James, Susan

2009-03-01

Portuguese immigrants to North America represent a large ethnic group with unique family therapy needs. The present study investigates acculturation and the family lives of Portuguese (Azorean) immigrants in Canada. Methods of analytic induction and constant comparison from grounded theory were used to examine transcripts of interviews with 21 Azorean immigrant women and 28 Azorean immigrant men. A model emerged wherein (a) immigration and acculturation act as stressors on the family unit, as described by the categories Process of Change and Family Relationships; (b) family members adopt generation- and gender-specific acculturative strategies, as illustrated by the categories Duas Culturas (Two Cultures) and Falando Portuges (Speaking Portuguese); and (c) as family members acculturate, discords arise and are resolved according to the cultural traits different members have adopted. The categories Discord Resolution and Preocupação (Preoccupations) illustrate this last dynamic. Implications for family therapy with immigrant families include an indication for community-level interventions, emphasis on confidentiality, awareness of acculturation stress and different acculturative strategies within the family, and aiding the family in the negotiation and integration of a new bicultural reality.

Lignocellulases from Armillaria gemina and Pholiota adiposa are efficient in hydrolyzing aspen and poplar biomass, respectively. In the present study, lignocellulosic enzymes obtained from a fungal consortium comprising P. adiposa and A. gemina were used for the saccharification of sunflower stalks. Sunflower stalks were thermochemically pretreated using 2 % NaOH at 50 °C for 24 h. The saccharification process parameters including substrate concentration, enzyme loading, pH, and temperature were optimized using response surface methodology to improve the saccharification yield. The highest enzymatic hydrolysis (84.3 %) was obtained using the following conditions: enzyme loading 10 FPU/g-substrate, substrate 5.5 %, temperature 50 °C, and pH 4.5. The hydrolysis yield obtained using the enzymes from the fungal consortium was equivalent to that obtained using a mixture of commercial enzymes Celluclast and Novozyme β-glucosidase. Addition of up to 500 ppm of heavy metal ions (As, Cu, Fe, Mn, Ni, Pb, and Zn) during saccharification did not significantly affect the saccharification yield. Thus, the biomass grown for phytoremediation of heavy metals can be used for the production of reducing sugars followed by ethanol fermentation.

Four Enterococcus faecium strains isolated from fermented products were evaluated for potential use as probiotic strains. In addition to efaAfm gene, commonly found in E. faecium food isolates, none of the isolates possessed virulence genes and none had positive reactions for the production of tyramine, histamine, putrescine and cadaverine in the screening medium used. All of these four isolates proved to be resistant to 65 °C. E. faecium 119 did not show antimicrobial activity against any of the target bacteria investigated. E. faecium 85 and 101 inhibited Listeria innocua and E. faecium DSMZ 13590. The strain E. faecium 120 inhibited seven target bacteria (Listeria monocytogenes 7946, L. monocytogenes 7947, L. innocua 2030c, L. innocua NCTC 11286, E. faecium DSMZ 13590, Enterococcus faecalis ATCC 29212 and Staphylococcus aureus ATCC 29213) and was chosen as the representative to assess the ability to survive gastrointestinal tract passage simulation, as well as the protective role of two food matrices (skim milk and Alheira) during its passage. For both matrices used, no significant differences (p<0.05) were obtained between the types of digestion - quick and slow passage simulation. In the skim milk matrix the isolate was reduced to values below the detection limit of the enumeration technique by the end of the two digestions, in contrast to the Alheira matrix, for which isolate 120 showed a reduction of only ca. 1 log CFU/ml. The E. faecium strain 120 was shown to be a potential candidate for further investigations as a potential probiotic culture. Copyright © 2014. Published by Elsevier B.V.

Biscaia, André Rosa; Heleno, Liliana Correia Valente

2017-03-01

The 2005 Portuguese primary health care (CSP) reform was one of the most successful reforms of the country's public services. The most relevant event was the establishment of Family Health Units (USF): voluntary and self-organized multidisciplinary teams that provide customized medical and nursing care to a group of people. Then, the remaining realms of CSP were reorganized with the establishment of Health Center Clusters (ACeS). Clinical governance was implemented aiming at achieving health gains by improving quality and participation and accountability of all. This paper aims to characterize the 2005 reform of Portuguese CSP with an analysis of its systemic and local realms. This is a case study of a CSP reform of a health system with documentary analysis and description of one of its facilities. This reform was Portuguese, modern and innovative. Portuguese by not breaking completely with the past, modern because it has adhered to technology and networking, and innovative because it broke with the traditional hierarchized model. It fulfilled the goal of a reform: it achieved improvements with greater satisfaction of all and health gains.

Twenty seven essential oils, isolated from plants representing 11 families of Portuguese flora, were screened for their nematicidal activity against the pinewood nematode (PWN), Bursaphelenchus xylophilus. The essential oils were isolated by hydrodistillation and the volatiles by distillation-extraction, and both were analysed by GC and GC-MS. High nematicidal activity was achieved with essential oils from Chamaespartium tridentatum, Origanum vulgare, Satureja montana, Thymbra capitata, and Thymus caespititius. All of these essential oils had an estimated minimum inhibitory concentration ranging between 0.097 and 0.374 mg/ml and a lethal concentration necessary to kill 100% of the population (LC100) between 0.858 and 1.984 mg/ml. Good nematicidal activity was also obtained with the essential oil from Cymbopogon citratus. The dominant components of the effective oils were 1–octen-3-ol (9%), n–nonanal, and linalool (both 7%) in C. tridentatum, geranial (43%), neral (29%), and β-myrcene (25%) in C. citratus, carvacrol (36% and 39%), γ-terpinene (24% and 40%), and p-cymene (14% and 7%) in O. vulgare and S. montana, respectively, and carvacrol (75% and 65%, respectively) in T. capitata and T. caespititius. The other essential oils obtained from Portuguese flora yielded weak or no activity. Five essential oils with nematicidal activity against PWN are reported for the first time. PMID:22736831

PONTES, HALLEY M.; PATRÃO, IVONE M.; GRIFFITHS, MARK D.

2014-01-01

Background and aims: Research into Internet addiction (IA) has increased greatly over the last decade. Despite its various definitions and general lack of consensus regarding its conceptualisation amongst researchers, instruments for measuring this phenomenon have proliferated in a number of countries. There has been little research on IA in Portugal and this may be partly due to the absence of standardised measurement tools for assessing IA. Methods: This study attempted to address this issue by adapting a Portuguese version of the Internet Addiction Test (IAT) via a translation-back translation process and Confirmatory Factor Analysis in a sample of 593 Portuguese students that completed a Portuguese version of the IAT along with questions related to socio-demographic variables. Results: The findings suggested that the IAT appears to be a valid and reliable instrument for measuring IA among Portuguese young adults as demonstrated by its satisfactory psychometric properties. However, the present findings also suggest the need to reword and update some of the IAT’s items. Prevalence of IA found in the sample was 1.2% and is discussed alongside findings relating to socio-demographic correlates. Limitations and implications of the present study are also discussed. Conclusions: The present study calls for a reflection of the IAT while also contributing to a better understanding of the basic aspects of IA in the Portuguese community since many health practitioners are starting to realise that Internet use may pose a risk for some individuals.

In line with self-determination theory (SDT: Deci & Ryan, 1985, 2002) the satisfaction of the basic psychological needs for autonomy, competence, and relatedness has been identified as an important predictor of behavior and optimal functioning in various contexts including exercise. The lack of a valid and reliable instrument to assess the extent to which these needs are fulfilled among Portuguese exercise participants limits the evaluation of causal links proposed by SDT in the Portuguese exercise context. The aim of the present study was to translate into Portuguese and validate the Basic Psychological Needs in Exercise Scale (BPNES: Vlachopoulos & Michailidou, 2006). Using data from 522 exercise participants the findings provided evidence of strong internal consistency of the translated BPNES subscales while confirmatory factor analysis supported a good fit of the correlated 3-factor model to the data. The present findings support the use of the translated into Portuguese BPNES to assess the extent of basic psychological need fulfilment among Portuguese exercise participants.

speech fluency varies from one individual to the next, fluent or stutterer, depending on several factors. Studies that investigate the influence of age on fluency patterns have been identified; however these differences were investigated in isolated age groups. Studies about life span fluency variations were not found. to verify the speech fluency developmental profile. speech samples of 594 fluent participants of both genders, with ages between 2:0 and 99:11 years, speakers of the Brazilian Portuguese language, were analyzed. Participants were grouped as follows: pre-scholars, scholars, early adolescence, late adolescence, adults and elderlies. Speech samples were analyzed according to the Speech Fluency Profile variables and were compared regarding: typology of speech disruptions (typical and less typical), speech rate (words and syllables per minute) and frequency of speech disruptions (percentage of speech discontinuity). although isolated variations were identified, overall there was no significant difference between the age groups for the speech disruption indexes (typical and less typical speech disruptions and percentage of speech discontinuity). Significant differences were observed between the groups when considering speech rate. the development of the neurolinguistic system for speech fluency, in terms of speech disruptions, seems to stabilize itself during the first years of life, presenting no alterations during the life span. Indexes of speech rate present variations in the age groups, indicating patterns of acquisition, development, stabilization and degeneration.

This article presents the results of a series of preliminary comparisons, between the Portuguese and Romanian cultural contexts, on the individualism-collectivism (IND/COL) cultural dimension. The IND/COL was evaluated with the Individualism-Collectivism Questionnaire - ICQ -, constructed in New Zealand by Shulruf, Hattie and Dixon (2003, Anonymous Questionnaire of Self-Attitudes - AQSA), and adapted to the Portuguese and Romanian contexts by Ciochină and Faria (2007), using studies of confirmatory factor analysis. The ICQ composed by 26 items, 15 evaluating the IND scale--with three subscales (Uniqueness, Competition and Responsibility)--, and 11 evaluating the COL scale--with two subscales (Harmony and Advice)--, was administered to 395 subjects, 200 Portuguese and 195 Romanian, 10th and 12th graders. On the whole, in the Portuguese and Romanian samples, the multivariate and univariate statistical analyses evidenced the existence of two independent variables--gender and cultural context--, with significant effects, main and of interaction, on the scales and subscales of the ICQ. The results were discussed taking into consideration the specificities of the educational systems in the two cultural contexts, which are inevitably shaped by socio-cultural factors characteristic of the two countries considered in the present study--Portugal and Romania.

To determine Portuguese dentists' role in addressing obesity. For this pilot study, the original version of the Dentists' Role In Addressing Obesity questionnaire was translated from English into Portuguese and validated to ensure that it was culturally adapted for Portuguese dentists. The questionnaire was distributed to a random sample of 400 Portuguese dentists. SPSS Statistics 20 was used to analyse the survey sampling design and assess respondents' attitudes and opinions, outcome expectations and self-efficacy both as ordinal and dichotomised variables. The analysis was a descriptive statistic based on frequencies, without symmetry test. In all, 141 dentists responded. Overall, 22.0% of respondents offered a form of counseling services and 58.9% reported that they were interested in offering obesity-related services. A paucity of trained personnel (58.9%) was cited by the respondents as a major barrier, followed by patients' rejection of weight-loss advice (32.6%) and fears of offending patients (29.1%). 92% of respondents agreed that dentists would be more willing to intervene if obesity were linked to oral disease. Healthcare providers must coordinate prevention and interventional efforts for maximum effect. Given the positioning of dentists willing to assist in such an effort, it appears reasonable for experts in obesity intervention in conjunction with dental educators to develop intervention models to be implemented within the scope of the dental practice.

To develop a version of the modified Japanese Orthopaedic Association (mJOA) scale that had been translated into Portuguese and cross-culturally adapted for the Brazilian population. The well-established process of forward-backward translation was employed along with cross-cultural adaptation. Three bilingual translators (English and native Portuguese) performed the forward translation of the mJOA scale from English to Portuguese based on iterative discussions used to reach a consensus translation. The translated version of the mJOA scale was then back-translated into English by a native English-speaking translator unaware of the concepts involved with the mJOA scale. The original mJOA scale and the back-translated version were compared by a native North American neurosurgeon, and as they were considered equivalent, the final version of the mJOA scale that had been translated into Portuguese and cross-culturally adapted was defined. To facilitate global and cross-cultural comparisons of the severity of cervical myelopathy, this study presents a version of the mJOA scale that was translated into Portuguese and cross-culturally adapted for the Brazilian population.

The Health Service Quality Scale is a multidimensional hierarchical scale that is based on interdisciplinary approach. This instrument was specifically created for measuring health service quality based on marketing and health care concepts. The aim of this study was to translate and culturally adapt the Health Service Quality Scale into Brazilian Portuguese and to assess the validity and reliability of the Brazilian Portuguese version of the instrument. We conducted a cross-sectional, observational study, with public health system patients in a Brazilian university hospital. Validity was assessed using Pearson's correlation coefficient to measure the strength of the association between the Brazilian Portuguese version of the instrument and the SERVQUAL scale. Internal consistency was evaluated using Cronbach's alpha coefficient; the intraclass (ICC) and Pearson's correlation coefficients were used for test-retest reliability. One hundred and sixteen consecutive postoperative patients completed the questionnaire. Pearson's correlation coefficient for validity was 0.20. Cronbach's alpha for the first and second administrations of the final version of the instrument were 0.982 and 0.986, respectively. For test-retest reliability, Pearson's correlation coefficient was 0.89 and ICC was 0.90. The culturally adapted, Brazilian Portuguese version of the Health Service Quality Scale is a valid and reliable instrument to measure health service quality.

There are widespread differences in overweight/obesity prevalence in children, and understanding the reasons for this is very important. The present study aims: (I) to conduct a meta-analysis on overweight/obesity prevalence in Portuguese children; (II) to identify differences in biological and behavioural characteristics between normal-weight and overweight/obese children; and (III) to investigate the importance of individual- and school-level correlates of variation in children’s BMI using multilevel modelling. A search was done for all published papers including Portuguese children during the last decade; further, 686 Portuguese children (9–11 years old) were sampled and their BMI, family income, maturity offset, nutritional habits, physical activity, sedentariness, sleep time, and school environment information were collected. Results showed a stabilization of overweight/obesity during the last decade, 30.6% (95%CI: 0.287–0.34) for boys, 28.4% (95%CI: 0.23–0.35) for girls, and 30.3% (95%CI: 0.27–0.34) for boys and girls together. Differences between weight groups were only found in individual-level biological traits. The multilevel analysis did not identify significant contributions of school-level variables to children’s BMI variation. In conclusion, no increase was found in the prevalence of overweight/obesity among Portuguese children since 2000. Normal-weight and overweight/obese children only differ in individual-level characteristics, and school context variables were not related to variation in BMI. PMID:25372884

2005-01-01

Background The picture of dog mtDNA diversity, as obtained from geographically wide samplings but from a small number of individuals per region or breed, has revealed weak geographic correlation and high degree of haplotype sharing between very distant breeds. We aimed at a more detailed picture through extensive sampling (n = 143) of four Portuguese autochthonous breeds – Castro Laboreiro Dog, Serra da Estrela Mountain Dog, Portuguese Sheepdog and Azores Cattle Dog-and comparatively reanalysing published worldwide data. Results Fifteen haplotypes belonging to four major haplogroups were found in these breeds, of which five are newly reported. The Castro Laboreiro Dog presented a 95% frequency of a new A haplotype, while all other breeds contained a diverse pool of existing lineages. The Serra da Estrela Mountain Dog, the most heterogeneous of the four Portuguese breeds, shared haplotypes with the other mainland breeds, while Azores Cattle Dog shared no haplotypes with the other Portuguese breeds. A review of mtDNA haplotypes in dogs across the world revealed that: (a) breeds tend to display haplotypes belonging to different haplogroups; (b) haplogroup A is present in all breeds, and even uncommon haplogroups are highly dispersed among breeds and continental areas; (c) haplotype sharing between breeds of the same region is lower than between breeds of different regions and (d) genetic distances between breeds do not correlate with geography. Conclusion MtDNA haplotype sharing occurred between Serra da Estrela Mountain dogs (with putative origin in the centre of Portugal) and two breeds in the north and south of the country-with the Castro Laboreiro Dog (which behaves, at the mtDNA level, as a sub-sample of the Serra da Estrela Mountain Dog) and the southern Portuguese Sheepdog. In contrast, the Azores Cattle Dog did not share any haplotypes with the other Portuguese breeds, but with dogs sampled in Northern Europe. This suggested that the Azores Cattle Dog

The Acceptance and Action Questionnaire-Trauma Specific (AAQ-TS) is a self-report measure designed to assess-trauma-related psychological (in)flexibility, as conceptualized in Acceptance and Commitment Therapy. However, there are no studies to date regarding its psychometric properties. This study explores such properties in the Portuguese version of the AAQ-TS, in Portuguese Colonial War Veterans. A Principal Components Analysis (PCA) was conducted in a sample from the general population of war Veterans (N=371). Confirmatory Factor Analysis (CFA) as well as reliability and convergent validity studies were performed in a different sample from the same population (N=312). For the discriminant validity a clinical sample with a war-related PTSD (N=42) and a non-clinical sample without PTSD (N=44) were used. The CFA suggested a re-specified 15-item model with good global adjustment and factorial validity. The AAQ-TS showed internal consistency, a good temporal reliability, convergent validity with psychopathological symptoms (related to PTSD, anxiety, depression and stress) and peritraumatic dissociation (altered awareness and depersonalization/derealization). The questionnaire also discriminates between war Veterans with and without a PTSD diagnosis. The major limitation relates to the samples' characteristics and sampling methods, which can limit the generalization of results. The Portuguese version of the AAQ-TS is a reliable and valid measure to assess experiential avoidance related to trauma in Portuguese Colonial War Veterans. Copyright © 2015 Elsevier B.V.

Individuals spend 80-90% of their day indoors and elderly subjects are likely to spend even a greater amount of time indoors. Thus, indoor air pollutants such as bioaerosols may exert a significant impact on this age group. The aim of this study was to characterize fungal contamination within Portuguese elderly care centers. Fungi were measured using conventional as well as molecular methods in bedrooms, living rooms, canteens, storage areas, and outdoors. Bioaerosols were evaluated before and after the microenvironments' occupancy in order to understand the role played by occupancy in fungal contamination. Fungal load results varied from 32 colony-forming units CFU m(-3) in bedrooms to 228 CFU m(-3) in storage areas. Penicillium sp. was the most frequently isolated (38.1%), followed by Aspergillus sp. (16.3%) and Chrysonilia sp. (4.2%). With respect to Aspergillus genus, three different fungal species in indoor air were detected, with A. candidus (62.5%) the most prevalent. On surfaces, 40 different fungal species were isolated and the most frequent was Penicillium sp. (22.2%), followed by Aspergillus sp. (17.3%). Real-time polymerase chain reaction did not detect the presence of A. fumigatus complex. Species from Penicillium and Aspergillus genera were the most abundant in air and surfaces. The species A. fumigatus was present in 12.5% of all indoor microenvironments assessed. The living room was the indoor microenvironment with lowest fungal concentration and the storage area was highest.

This paper comprises two studies which address the validity of the Portuguese adaptation of the Gudjonsson Suggestibility Scale, GSS1. In study 1, the means and standard deviations for the suggestibility results of a sample of Portuguese inmates (N=40, Mage=37.5 years, SD=8.1) were compared to those of a sample of Icelandic inmates (Gudjonsson, 1997; Gudjonsson & Sigurdsson, 1996). Portuguese inmates' results were in line with the original results. In study 2, the means and standard deviations for the suggestibility results of the sample of Portuguese inmates were compared to those of a general Portuguese population sample (N=57, Mage=36.1 years, SD=12.7). The forensic sample obtained significantly higher scores in suggestibility measures than the general population sample. ANOVA confirmed that the increased suggestibility in the inmates sample was due to the limited memory capacity of this latter group. Given that the results of both studies 1 and 2 are in keeping with the author's original results (Gudjonsson, 1997), this may be regarded as a confirmation of the validity of the Portuguese GSS1.

De Marco, P; Murrell, J C; Bordalo, A A; Moradas-Ferreira, P

2000-02-01

Two novel bacterial strains that can utilize methanesulfonic acid as a source of carbon and energy were isolated from a soil sample collected in northern Portugal. Morphological, physiological, biochemical and molecular biological characterization of the two isolates indicate that strain P1 is a pink-pigmented facultative methylotroph belonging to the genus Methylobacterium, while strain P2 is a restricted methylotroph belonging to the genus Hyphomicrobium. Both strains are strictly aerobic, degrade methanesulfonate, and release small quantities of sulfite into the medium. Growth on methanesulfonate induces a specific polypeptide profile in each strain. This, together with the positive hybridization to a DNA probe that carries the msm genes of Methylosulfonomonas methylovora strain M2, strongly endorses the contention that a methanesulfonic acid monooxygenase related to that found in the previously known methanesulfonate-utilizing bacteria is present in strains P1 and P2. The isolation of bacteria containing conserved msm genes from diverse environments and geographical locations supports the hypothesis that a common enzyme may be globally responsible for the oxidation of methanesulfonate by natural methylotrophic communities.

Sexual dysfunction is common in patients with psychotic illness. This article describes the translation and cross-cultural adaptation of the Sexual Function Questionnaire (SFQ) into Brazilian Portuguese. The translation and cross-cultural adaptation followed the guidelines for adapting self-report instruments proposed by the Task Force of the International Society for Pharmacoeconomics and Outcomes Research (ISPOR). Briefly, ISPOR steps include: preparation, forward translation, reconciliation, back-translation, back-translation review, harmonization, cognitive debriefing, review of cognitive debriefing and finalization, before proofreading and final version. The original authors authorized the translation and participated in the study. There was good agreement between translations and between the back-translation and the original English version of the SFQ. The final version was prepared with certificated evaluators in the original language and in Portuguese. Few changes were necessary to the new version in Portuguese. The translated and adapted Brazilian Portuguese version of the SFQ is reliable and semantically equivalent to the original version. Studies on psychotropic-related sexual dysfunction may now test the validity of the instrument and can investigate sexual dysfunction in Portuguese-speaking patients.

The work environment in Portuguese hospitals, characterized by economic cutbacks, can lead to higher levels of burnout experienced by nursing staff. Furthermore, vulnerability to stress can negatively affect the perception of burnout in the workplace. However, structural empowerment is an organizational process that can prevent and decrease burnout among nurses. Consequently, the aim of the study was to examine to what extent structural empowerment and vulnerability to stress can play a predictive role in core burnout in a sample of Portuguese nurses. A convenience sample of 297 nursing staff members from Portuguese hospitals was used in this study. Core burnout was negatively and significantly related to all the dimensions of structural empowerment, and it was positively and significantly related to vulnerability to stress. Regression models showed that core burnout was significantly predicted by access to funds, access to opportunities and vulnerability to stress. Organizational administrations must make every effort in designing interventions focused on structural empowerment, as well as interventions focused on individual interventions that enhance skills for coping with stress.

Genetic evaluation of Addison's disease in the Portuguese Water Dog

2006-01-01

Background Addison's disease, also known as hypoadrenocorticism, has been reported in many individual dogs, although some breeds exhibit a greater incidence than the population as a whole. Addison's is presumed to be an autoimmune mediated hereditary defect but the mode of inheritance remains unclear. In particular, the heritability and mode of inheritance have not been defined for the Portuguese Water Dog although Addison's is known to be prevalent in the breed. Results The analyses present clear evidence that establishes Addison's disease as an inherited disorder in the Portuguese Water Dog with an estimate of heritability of 0.49 (± 0.16); there were no differences in risk for disease across sexes (p > 0.49). Further, the complex segregation analysis provides suggestive evidence that Addison's disease in the Portuguese Water Dog is inherited under the control of a single, autosomal recessive locus. Conclusion The high heritability and mode of inheritance of Addison's disease in the Portuguese Water Dog should enable the detection of segregating markers in a genome-wide scan and the identification of a locus linked to Addison's. Though the confirmation of Addison's disease as an autosomal recessive disorder must wait until the gene is identified, breeders of these dogs may wish to keep the present findings in mind as they plan their breeding programs to select against producing affected dogs.

Genomic and Proteomic Dissection of the Ubiquitous Plant Pathogen, Armillaria mellea: Toward a New Infection Model System

PubMed Central

2013-01-01

Armillaria mellea is a major plant pathogen. Yet, no large-scale “-omics” data are available to enable new studies, and limited experimental models are available to investigate basidiomycete pathogenicity. Here we reveal that the A. mellea genome comprises 58.35 Mb, contains 14473 gene models, of average length 1575 bp (4.72 introns/gene). Tandem mass spectrometry identified 921 mycelial (n = 629 unique) and secreted (n = 183 unique) proteins. Almost 100 mycelial proteins were either species-specific or previously unidentified at the protein level. A number of proteins (n = 111) was detected in both mycelia and culture supernatant extracts. Signal sequence occurrence was 4-fold greater for secreted (50.2%) compared to mycelial (12%) proteins. Analyses revealed a rich reservoir of carbohydrate degrading enzymes, laccases, and lignin peroxidases in the A. mellea proteome, reminiscent of both basidiomycete and ascomycete glycodegradative arsenals. We discovered that A. mellea exhibits a specific killing effect against Candida albicans during coculture. Proteomic investigation of this interaction revealed the unique expression of defensive and potentially offensive A. mellea proteins (n = 30). Overall, our data reveal new insights into the origin of basidiomycete virulence and we present a new model system for further studies aimed at deciphering fungal pathogenic mechanisms.

Portuguese Lexical Clusters and CVC Sequences in Speech Perception and Production.

Cunha, Conceição

2015-01-01

This paper investigates similarities between lexical consonant clusters and CVC sequences differing in the presence or absence of a lexical vowel in speech perception and production in two Portuguese varieties. The frequent high vowel deletion in the European variety (EP) and the realization of intervening vocalic elements between lexical clusters in Brazilian Portuguese (BP) may minimize the contrast between lexical clusters and CVC sequences in the two Portuguese varieties. In order to test this hypothesis we present a perception experiment with 72 participants and a physiological analysis of 3-dimensional movement data from 5 EP and 4 BP speakers. The perceptual results confirmed a gradual confusion of lexical clusters and CVC sequences in EP, which corresponded roughly to the gradient consonantal overlap found in production. © 2015 S.

Phonologic-graphemic transcodifier for Portuguese Language spoken in Brazil (PLB)

NASA Astrophysics Data System (ADS)

Fragadasilva, Francisco Jose; Saotome, Osamu; Deoliveira, Carlos Alberto

An automatic speech-to-text transformer system, suited to unlimited vocabulary, is presented. The basic acoustic unit considered are the allophones of the phonemes corresponding to the Portuguese language spoken in Brazil (PLB). The input to the system is a phonetic sequence, from a former step of isolated word recognition of slowly spoken speech. In a first stage, the system eliminates phonetic elements that don't belong to PLB. Using knowledge sources such as phonetics, phonology, orthography, and PLB specific lexicon, the output is a sequence of written words, ordered by probabilistic criterion that constitutes the set of graphemic possibilities to that input sequence. Pronunciation differences of some regions of Brazil are considered, but only those that cause differences in phonological transcription, because those of phonetic level are absorbed, during the transformation to phonological level. In the final stage, all possible written words are analyzed for orthography and grammar point of view, to eliminate the incorrect ones.

The cross-cultural adaptation and validation of the Sniffin`Sticks test for the Portuguese population is described. Over 270 people participated in four experiments. In Experiment 1, 67 participants rated the familiarity of presented odors and seven descriptors of the original test were adapted to a Portuguese context. In Experiment 2, the Portuguese version of Sniffin`Sticks test was administered to 203 healthy participants. Older age, male gender and active smoking status were confirmed as confounding factors. The third experiment showed the validity of the Portuguese version of Sniffin`Sticks test in discriminating healthy controls from patients with olfactory dysfunction. In Experiment 4, the test-retest reliability for both the composite score (r71 = 0.86) and the identification test (r71 = 0.62) was established (p<0.001). Normative data for the Portuguese version of Sniffin`Sticks test is provided, showing good validity and reliability and effectively distinguishing patients from healthy controls with high sensitivity and specificity. The Portuguese version of Sniffin`Sticks test identification test is a clinically suitable screening tool in routine outpatient Portuguese settings. PMID:26863023

Objective: To translate the Leicester Cough Questionnaire (LCQ) to Portuguese and adapt it for use in Brazil. Methods: Cross-cultural adaptation of a quality of life questionnaire requires a translated version that is conceptually equivalent to the original version and culturally acceptable in the target country. The protocol used consisted of the translation of the LCQ to Portuguese by three Brazilian translators who were fluent in English and its back-translation to English by another translator who was a native speaker of English and fluent in Portuguese. The back-translated version was evaluated by one of the authors of the original questionnaire in order to verify its equivalence. Later in the process, a provisional Portuguese-language version was thoroughly reviewed by an expert committee. In 10 patients with chronic cough, cognitive debriefing was carried out in order to test the understandability, clarity, and acceptability of the translated questionnaire in the target population. On that basis, the final Portuguese-language version of the LCQ was produced and approved by the committee. Results: Few items were questioned by the source author and revised by the committee of experts. During the cognitive debriefing phase, the Portuguese-language version of the LCQ proved to be well accepted and understood by all of the respondents, which demonstrates the robustness of the process of translation and cross-cultural adaptation. Conclusions: The final version of the LCQ adapted for use in Brazil was found to be easy to understand and easily applied. PMID:25029643

The manufacture of dry fermented sausages is an important part of the meat industry in Southern European countries. These products are usually produced in small shops from a mixture of pork, fat, salt, and condiments and are stuffed into natural casings. Meat sausages are slowly cured through spontaneous fermentation by autochthonous microbiota present in the raw materials or introduced during manufacturing. The aim of this work was to evaluate the technological and safety features of coagulase-negative staphylococci (CNS) isolated from Portuguese dry fermented meat sausages in order to select autochthonous starters. Isolates (n = 104) obtained from 2 small manufacturers were identified as Staphylococcus xylosus, Staphylococcus equorum, Staphylococcus saprophyticus, and Staphylococcus carnosus. Genomically diverse isolates (n = 82) were selected for further analysis to determine the ability to produce enzymes (for example, nitrate-reductases, proteases, lipases) and antibiotic susceptibility. Autochthonous CNS producing a wide range of enzymes and showing low antibioresistance were selected as potential starters for future use in the production of dry fermented meat sausages. © 2016 Institute of Food Technologists®

Clinical and environmental samples from Portugal were screened for the presence of Aspergillus and the distributions of the species complexes were determined in order to understand how their distributions differ based on their source. Fifty-seven Aspergillus isolates from clinical samples were collected from 10 health institutions. Six species complexes were detected by internal transcribed spacer sequencing; Fumigati, Flavi, and Nigri were found most frequently (50.9%, 21.0%, and 15.8%, respectively). β-tubulin and calmodulin sequencing resulted in seven cryptic species (A. awamorii, A. brasiliensis, A. fructus, A. lentulus, A. sydowii, A. tubingensis, Emericella echinulata) being identified among the 57 isolates. Thirty-nine isolates of Aspergillus were recovered from beach sand and poultry farms, 31 from swine farms, and 80 from hospital environments, for a total 189 isolates. Eleven species complexes were found in these 189 isolates, and those belonging to the Versicolores species complex were found most frequently (23.8%). There was a significant association between the different environmental sources and distribution of the species complexes; the hospital environment had greater variability of species complexes than other environmental locations. A high prevalence of cryptic species within the Circumdati complex was detected in several environments; from the isolates analyzed, at least four cryptic species were identified, most of them growing at 37ºC. Because Aspergillus species complexes have different susceptibilities to antifungals, knowing the species-complex epidemiology for each setting, as well as the identification of cryptic species among the collected clinical isolates, is important. This may allow preventive and corrective measures to be taken, which may result in decreased exposure to those organisms and a better prognosis. © The Author 2014.

Since June 2008, Portuguese rheumatologists have been collecting on a routine basis, data into the nationwide Reuma.pt, the Rheumatic Diseases Portuguese Register from the Portuguese Society of Rheumatology (SPR), which includes rheumatic patients (rheumatoid arthritis - RA, ankylosing spondylitis - AS, psoriatic arthritis - PsA and juvenile idiopathic arthritis - JIA) receiving biological therapies or patients receiving synthetic disease modifying anti-rheumatic drugs (DMARDs). The aim of this publication is to describe the structure of Reuma.pt and the population registered since June 2008. Demographic and anthropometric data, life style habits, work status, co-morbidities, disease activity and functional assessment scores, previous and current therapies, adverse events codified by the Medical Dictionary for Regulatory Activities (MedDRA), reasons for discontinuation and laboratory measurements are registered at each visit. The platform is based on a structured electronic medical record linked to a SQL Server database. All Rheumatology Departments assigned to the Portuguese National Health Service (n=21), 2 Military Hospitals (Lisboa and Porto), 1 public-private Institution and 6 private centers adhered to the Register. Until now, 18 centers have entered data into Reuma.pt. By January 2011, 3438 patients and 16130 visits had been registered. 2162 (63%) were RA patients, 700 of them treated with biological agents and 1462 with synthetic DMARDs. From the 515 (15%) AS patients, 297 were medicated with biological and 218 with non-biological therapies. 293 (8%) were PsA patients, 151 treated with biological drugs and 142 with other treatment strategies. 368 (11%) had the diagnosis of JIA, 68 were under biological treatment and 300 were managed with other treatment options. The register also includes 100 (3%) patients with other rheumatic diseases, submitted to treatments that required hospital day care infusions including 18 exposed to biological therapies. Registers

The aim of the present study was to evaluate iodine intake in portuguese school children in order to inform health authorities of eventual measures to be implemented. Iodine is the key element for thyroid hormone synthesis and its deficiency even mild, as found in other European countries, may have deleterious effects in pregnancy resulting in cognitive problems of offsprings. In Portugal there are no recent data on iodine intake in schoolchildren. 3680 children aged 6-12 years of both sexes, from 78 different schools were studied. Iodine intake was evaluated trough urine iodine (UI) determinations using a colorimetic method. The global median UI value was 105.5 µg/L; the percentage of children with UI <100 µg/L was 47.1%, corresponding to 41% of the studied schools. The percentage of values <50 µg/L was 11.8%. The male gender, the south region of the country and the distribution of milk in school were significantly linked with a higher iodine elimination. Our global results point to a borderline/ mildly insufficient iodine intake in the portuguese school population. However 47% of the children had UI under 100 µg /L. The comparison of our results with the available data from 30 years ago, point to a considerable improvement, due to silent prophylaxis. Male gender, geographical area and milk distribution influenced positively iodine intake.The importance of milk has been referred in numerous papers. The study of UI in the Portuguese school population points to a borderline iodine intake. However, in 47% of children iodine intake was inadequate. Compared with data from the eighties, a considerable increase in iodine elimination was found. Taking into account the potencial deleterious effects of inadequate iodine intake, a global prophylaxis with salt iodization has to be considered.

This study examined Portuguese-speaking women's definitions of wife abuse and beliefs about appropriate responses to abuse. The goals were to determine the breadth of definitions and to examine cultural stereotyping. This information was sought in an effort to design education strategies in the Portuguese-speaking community. One-on-one semistructured interviews were conducted with 163 Portuguese-speaking women living in Toronto, Canada. The participants' open-ended answers were first coded using Qualitative Software Research NUDIST and then narrowed and grouped. Responses were then tagged by group label to generate descriptive statistics using Statistical Package for Social Sciences. Participants defined wife abuse broadly with respect to kind, prevalence, and severity. Six themes for abuse emerged: physical, psychological, sexual, financial, patriarchal, and infidelity. Participants provided various responses to what women should do and actually do in response to abuse. Most participants believed that Portuguese-speaking women should leave their husbands and/or seek help for the abuse, but that they actually remain quiet about the abuse and take very little action. Their responses and explanations demonstrate that they hold stereotypes about their culture. The range of definitions reported by participants suggests that a continuum of wife abuse, using Portuguese-speaking women's own words, can be created to educate them about how abusive acts are linked and used to maintain control over women. The differences that emerged with respect to appropriate responses to abuse suggest that it may be important to challenge Portuguese-speaking women about the cultural stereotypes that they hold to help them see patriarchy as widespread rather than particular to their culture.

The scope of this work is to conduct the cross-cultural adaptation from Spanish to European Portuguese of a questionnaire to measure the degree of "Patient Knowledge about their Medications" (CPM-ES-ES). A method based on six steps was applied: 1. Translation into Portuguese, 2. Elaboration of the first consensus version in Portuguese; 3.Back-translation into Spanish; 4. Elaboration of the second consensus version (cultural equivalency); 5. Conducting the pre-test; 6. Evaluation of the overall results. A cross-culturally adapted questionnaire in European Portuguese that measures the degree of "Patient Knowledge about their Medications" is proposed. The pre-test confirmation obtained 100% agreement with the corrected version of the second consensus version after pre-testing. The methodology selected made it possible to cross-culturally adapt the Spanish version of the CPM-ES-ES questionnaire to the Portuguese version. Further studies should demonstrate the equivalence of the psychometric properties of the cross-cultural translation into Portuguese with the original version.

No previous study has examined the prevalence of cardiovascular risk factors and explored the influence of immigration status and acculturation on overweight/obesity among the Portuguese immigrants to Luxembourg. Our objectives were to (1) compare the prevalence of cardiovascular risk factors between native Luxembourgers and Portuguese immigrants, (2) examine the relationship between immigrant generation status, proportion of life spent in Luxembourg and language proficiency or preference (as proxy variables of acculturation) and overweight/obesity among Portuguese immigrants, and (3) elucidate the role of underlying socioeconomic, behavioral and dietary factors in overweight/obesity differences among the two populations. Recent national cross-sectional data from ORISCAV-LUX survey 2007-2008, composed of 843 subjects were analyzed. Overweight/obesity was defined as body mass index (BMI) >25 kg/m(2). Acculturation score was measured by using immigrant generation status, proportion of life spent in Luxembourg, and language proficiency or preference. Univariable and multivariable logistic regression analyses were performed to examine the association between acculturation markers and overweight/obesity. Further, a series of successive models were fitted to explore the separated and added impact of potential mediators (socioeconomic status, physical activity, dietary factors) on overweight/obesity among Luxembourgers and Portuguese immigrants. Compared to Luxembourgers, Portuguese immigrants of first and second generation were younger and currently employed. About 68% of first generation Portuguese had only primary school, and about 44% were living below poverty threshold. Although the cardiovascular risk factors were comparable, Portuguese immigrants were more frequently overweight and obese than Luxembourgers, even after age and gender standardization to the European population. Overweight/obesity was significantly higher among Portuguese of first generation compared

Brazil has received influxes of people, mainly from Africa, Europe and Japan, forming one of the most heterogeneous populations in the world. Some groups, particularly in Southern Brazil, have retained their original cultural traditions, whilst acquiring elements of the typical local Brazilian cultural identity. This is the first study designed to formally evaluate biculturality in Brazil. To psychometrically assess and validate the Portuguese version of the Bicultural Scale (BS) in Brazil. The BS was adapted and translated to Portuguese and tested for the first time in Brazil in a sample of descendants (n = 160) from four immigrant groups and respective locations in Southern Brazil. A series of psychometric tests were conducted in order to examine the validity of the Portuguese version of the BS. Analyses of variance across scores for all subgroups were also conducted. Factor analysis revealed two main factors contributing to most of the variance in scores. The 10 items measuring affiliation with minority cultural characteristics and the typical Brazilian culture yielded Cronbach's alpha coefficients of 0.69 and 0.78 respectively, whereas the overall Cronbach's alpha for all 20 items of the BS was 0.67. There was a significant correlation between items related to the typical Brazilian culture and the generation since immigration of research participants (r = 0.23, p = 0.004). The mean time taken to complete the questionnaire was 7.4 minutes. The results indicate that the Portuguese version of the BS is a valid, reliable and easy-to-use instrument to assess biculturality experienced by descendants of immigrants in southern Brazil.

Brand names of Portuguese medication: understanding the importance of their linguistic structure and regulatory issues.

Among other regulatory requirements, medicine brands should be composed of single names without abbreviations to prevent errors in prescription of medication. The purposes of the study were to investigate the compliance of a sam ple of Portuguese medicine brand names with Portuguese pharmaceutical regulations. This includes identifying their basic linguistic characteristics and comparing these features and their frequency of occurrence with benchmark values of the colloquial or informal language. A sample of 474 brand names was selected. Names were analyzed using manual (visual analyses) and computer methods (FreP - Frequency Patterns of Phonological Objects in Portuguese and MS word). A significant number of names (61.3%) failed to comply with the Portuguese phonologic system (related to the sound of words) and/or the spelling system (related to the written form of words) contained more than one word, comprised a high proportion of infrequent syllable types or stress patterns and included abbreviations. The results suggest that some of the brand names of Portuguese medication should be reevaluated, and that regulation on this issue should be enforced and updated, taking into consideration specific linguistic and spelling codes.

Portuguese Ornamental Stones - Identity and Cultural Heritage around the World

2016-04-01

Portugal has established itself as an independent state on October, 5th 1143 being confined to the south-eastern tip of Europe, with sealed land access to the rest of the continent by the others Iberian Peninsula kingdoms, enemies at the time who did not accept Portuguese autonomy. From the fourteenth century, the history of Portugal reports a period of epic discoveries. New commercial maritime routes have been established. Those routes sailing around Africa, passing through India, drove Portuguese people to Macao and Timor. To the East other routes reach the South American continent. Besides commercial interest, and because the church also financed these trips, they had the mission to evangelize the native peoples that were found. In every formed captaincies, over 29 actual countries, numerous churches, hospitals and fortifications were built. Combining a long tradition and mastery of monumental stone building and stonemasonry, which dates back to the Roman Period, Portuguese were able to combine the need to provide ships stability, using already worked stone as ballast. When arrived to these remote locations, quickly and with few local resources, could erect towering and admirable structures that still prevail today. Most of these regions were colonized and gave rise to independent countries in the 70's of the 20th Century, in some of them Portuguese is the official language and these constitutes the Community of Portuguese Language Countries (CPLP). This work shows that in addition to the language, traditions, customs, and architecture, there's also a very rich Portuguese Natural Stones monumental heritage building record, which constitutes a very strong link that binds this so special community.

Acculturation, immigration status and cardiovascular risk factors among Portuguese immigrants to Luxembourg: findings from ORISCAV-LUX study

PubMed Central

2012-01-01

Background No previous study has examined the prevalence of cardiovascular risk factors and explored the influence of immigration status and acculturation on overweight/obesity among the Portuguese immigrants to Luxembourg. Our objectives were to (1) compare the prevalence of cardiovascular risk factors between native Luxembourgers and Portuguese immigrants, (2) examine the relationship between immigrant generation status, proportion of life spent in Luxembourg and language proficiency or preference (as proxy variables of acculturation) and overweight/obesity among Portuguese immigrants, and (3) elucidate the role of underlying socioeconomic, behavioral and dietary factors in overweight/obesity differences among the two populations. Methods Recent national cross-sectional data from ORISCAV-LUX survey 2007–2008, composed of 843 subjects were analyzed. Overweight/obesity was defined as body mass index (BMI) >25kg/m2. Acculturation score was measured by using immigrant generation status, proportion of life spent in Luxembourg, and language proficiency or preference. Univariable and multivariable logistic regression analyses were performed to examine the association between acculturation markers and overweight/obesity. Further, a series of successive models were fitted to explore the separated and added impact of potential mediators (socioeconomic status, physical activity, dietary factors) on overweight/obesity among Luxembourgers and Portuguese immigrants. Results Compared to Luxembourgers, Portuguese immigrants of first and second generation were younger and currently employed. About 68% of first generation Portuguese had only primary school, and about 44% were living below poverty threshold. Although the cardiovascular risk factors were comparable, Portuguese immigrants were more frequently overweight and obese than Luxembourgers, even after age and gender standardization to the European population. Overweight/obesity was significantly higher among Portuguese of

The increase in prisoner population is a troublesome reality in several regions of the world. Along with this growth there is increasing evidence that prisoners have a higher proportion of mental illnesses and suicide than the general population. In order to implement strategies that address criminal recidivism and the health and social status of prisoners, particularly in mental disordered offenders, it is necessary to assess their care needs in a comprehensive, but individual perspective. This assessment must include potential harmful areas like comorbid personality disorder, substance misuse and offending behaviours. The Camberwell Assessment of Need - Forensic Version (CANFOR) has proved to be a reliable tool designed to accomplish such aims. The present study aimed to validate the CANFOR Portuguese version. The translation, adaptation to the Portuguese context, back-translation and revision followed the usual procedures. The sample comprised all detainees receiving psychiatric care in four forensic facilities, over a one year period. A total of 143 subjects, and respective case manager, were selected. The forensic facilities were chosen by convenience: one prison hospital psychiatric ward (n=68; 47.6%), one male (n=24; 16.8%) and one female (n=22; 15.4%) psychiatric clinic and one civil security ward (n=29; 20.3%), all located nearby Lisbon. Basic descriptive statistics and Kappa weighted coefficients were calculated for the inter-rater and the test-retest reliability studies. The convergent validity was evaluated using the Global Assessment of Functioning and the Brief Psychiatric Rating Scale scores. The majority of the participants were male and single, with short school attendance, and accused of a crime involving violence against persons. The most frequent diagnosis was major depression (56.1%) and almost half presented positive suicide risk. The reliability study showed average Kappa weighted coefficients of 0.884 and 0.445 for inter-rater and test

This cross-sectional study was designed to develop normative functional fitness standards for the Portuguese older adults, to analyze age and gender patterns of decline, to compare the fitness level of Portuguese older adults with that of older adults in other countries, and to evaluate the fitness level of Portuguese older adults relative to recently published criterion fitness standards associated with maintaining physical independence. A sample of 4,712 independent-living older adults, age 65-103 yr, was evaluated using the Senior Fitness Test battery. Age-group normative fitness scores are reported for the 10th, 25th, 50th, 75th, and 90th percentiles. Results indicate that both women and men experience age-related losses in all components of functional fitness, with their rate of decline being greater than that observed in other populations, a trend which may cause Portuguese older adults to be at greater risk for loss of independence in later years. These newly established normative standards make it possible to assess individual fitness level and provide a basis for implementing population-wide health strategies to counteract early loss of independence.

Overactive Bladder (OAB) is a clinical condition characterized by symptoms reported by patients. Therefore, measurement instruments based on reported information are important for understanding its impact and treatment benefits. The aim of this study was to translate, culturally adapt and validate the Urgency Questionnaire (UQ) in Portuguese. Initially, the UQ was translated and culturally adapted to Portuguese. Sixty-three volunteers were enrolled in the study and were interviewed for responding the Portuguese version of the UQ and the validated Portuguese version of the Overactive Bladder Questionnaire short-form (OABq-SF), used as the gold standard measurement for the validation process. Psychometric properties such as criterion validity, stability, and reliability were tested. Forty-six subjects were included in the symptomatic group (presence of "urgency"), and seventeen were included in the asymptomatic group (control group). There was difference between symptomatic and asymptomatic subjects on all of the subscales (p≤0.001). The UQ subscales correlated with the OABq-SF subscales (p≤0.01), except the subscale "time to control urgency" and the item "impact" from the visual analog scales (VAS). However, these scales correlated with the OABq-SF - Symptom Bother Scale. The UQ subscales demonstrated stability over time (p<0.05), but the subscale "fear of incontinence" and the item "severity" of the VAS did not. All of the UQ subscales showed internal consistencies that were considered to be good or excellent. The Portuguese version of the UQ proved to be a valid tool for the evaluation of OAB in individuals whose native language is Portuguese. Copyright® by the International Brazilian Journal of Urology.

To validate the Portuguese version of the Children's Sleep Habits Questionnaire (CSHQ-PT) and compare it to the versions from other countries. The questionnaire was previously adapted to the Portuguese language according to international guidelines. 500 questionnaires were delivered to the parents of a Portuguese community sample of children aged 2 to 10 years old. 370 (74%) valid questionnaires were obtained, 55 children met exclusion criteria and 315 entered in the validation study. The CSHQ-PT internal consistency (Cronbach's α) was 0.78 for the total scale and ranged from 0.44 to 0.74 for subscales. The test-retest reliability for subscales (Pearson's correlations, n=58) ranged from 0.59 to 0.85. Our data did not adjust to the original 8 domains structure in Confirmatory Factor Analysis but the Exploratory Factor Analysis extracted 5 factors that have correspondence to CSHQ subscales. The CSHQ-PT evidenced psychometric properties that are comparable to the versions from other countries and adequate for the screening of sleep disturbances in children from 2 to 10 years old.

Despite numerous spirituality and/or religiosity (S/R) measurement tools for use in research worldwide, there is little information on S/R instruments in the Portuguese language. The aim of the present study was to map out the S/R scales available for research in the Portuguese language. Systematic review of studies found in databases. A systematic review was conducted in three phases. Phases 1 and 2: articles in Portuguese, Spanish and English, published up to November 2011, dealing with the Portuguese translation and/or validation of S/R measurement tools for clinical research, were selected from six databases. Phase 3: the instruments were grouped according to authorship, cross-cultural adaptation, internal consistency, concurrent and discriminative validity and test-retest procedures. Twenty instruments were found. Forty-five percent of these evaluated religiosity, 40% spirituality, 10% religious/spiritual coping and 5% S/R. Among these, 90% had been produced in (n = 3) or translated to (n = 15) Brazilian Portuguese and two (10%) solely to European Portuguese. Nevertheless, the majority of the instruments had not undergone in-depth psychometric analysis. Only 40% of the instruments presented concurrent validity, 45% discriminative validity and 15% a test-retest procedure. The characteristics of each instrument were analyzed separately, yielding advantages, disadvantages and psychometric properties. Currently, 20 instruments for measuring S/R are available in the Portuguese language. Most have been translated (n = 15) or developed (n = 3) in Brazil and present good internal consistency. Nevertheless, few instruments have been assessed regarding all their psychometric qualities.

Marques, Rui Cunha; Simões, Pedro

2009-03-01

Measuring the performance of solid waste management services usually uncovers very high potential for gains in efficiency and productivity. This circumstance occurs, naturally, due to the fact that these services are outside the market and because they are subjected to various market failures in their organizational framework. The aim of this study was to examine the Portuguese regulatory model and to measure the performance of the Portuguese solid waste management services in order to identify the major reforms carried out and their outcomes. As a first objective, the sunshine regulatory approach adopted in Portugal, in which performance comparison and its public discussion are the main tools, was investigated. The second objective was to compute the efficiency of the Portuguese solid waste management services by means of the non-parametric technique of data envelopment analysis (DEA), evaluating the Portuguese regulatory model and the existing market structure, as well as the influence of the operational environment on efficiency. The benchmarking frontier technique of DEA is particularly useful in the efficiency measurement of public utilities, in which knowledge of the production function is relatively scarce. Several DEA models were used and they all depicted significant inefficiency. The study also proved that efficiency did not depend on ownership (public or private) and that there was no difference in efficiency between the players, irrespective of whether they were regulated or not.

The Portuguese Lioz, a Monumental Limestone

NASA Astrophysics Data System (ADS)

Silva, Zenaide

2017-04-01

Lioz is a microcrystalline limestone which occurs in Portugal and outcrops in the Lisbon area and its neighboring counties Oeiras, Pero Pinheiro, Lameiras. The rock is whitish to light and dark pink and contains 120 million years old rudists fossils. This fossiliferous content imprints a decorative aspect to the rock contributing to its very wide use as construction material and its favorite use in churches and official monuments making it the Royal Stone in Portugal along the XVII and XVIII centuries. Lisbon has the best exposition of Lioz as a fundamental stone in several monuments, the best examples being the Jeronimos Monastery, the Belém Tower, the Cultural Center in Belém and many old churches spread in Lisbon area. Among the latter the Jesuit Church of São Roque is a special example. The fact that the rock stratigraphic sequence allows the different rock colors as white, light and dark pink and a yellow facies variety in a local occurrence (Negrais yellow) makes it a special source for decorative patterns that can be found in a few churches in Lisbon, Évora, Mafra exhibiting "embutidos" technique, of indian origin and inspired on contemporaneous Italian churches. Mafra is the place where a monumental architectural set, composed by three integrated constructions, was built in the XVIII century by king D.João V using Lioz limestone as the main rock material, in all available colors. Along the XVII and XVIII centuries, the rock was transported to some portuguese colonies, mainly as ballast to improve the navigability of the boats, and used at the destinations as construction material for monuments, official buildings and churches. Brazil and especially Salvador, in Bahia, is the best example of that, where Lioz is beautifully exposed in monuments and as true art in many churches where the Portuguese or Italian influences are very strong. All these facts make the Portuguese Lioz Limestone as very representative of the Heritage present in Portugal and its

Toxin Profile of Gymnodinium catenatum (Dinophyceae) from the Portuguese Coast, as Determined by Liquid Chromatography Tandem Mass Spectrometry

Costa, Pedro R.; Robertson, Alison; Quilliam, Michael A.

2015-01-01

The marine dinoflagellate Gymnodinium catenatum has been associated with paralytic shellfish poisoning (PSP) outbreaks in Portuguese waters for many years. PSP syndrome is caused by consumption of seafood contaminated with paralytic shellfish toxins (PSTs), a suite of potent neurotoxins. Gymnodinium catenatum was frequently reported along the Portuguese coast throughout the late 1980s and early 1990s, but was absent between 1995 and 2005. Since this time, G. catenatum blooms have been recurrent, causing contamination of fishery resources along the Atlantic coast of Portugal. The aim of this study was to evaluate the toxin profile of G. catenatum isolated from the Portuguese coast before and after the 10-year hiatus to determine changes and potential impacts for the region. Hydrophilic interaction liquid chromatography tandem mass spectrometry (HILIC-MS/MS) was utilized to determine the presence of any known and emerging PSTs in sample extracts. Several PST derivatives were identified, including the N-sulfocarbamoyl analogues (C1–4), gonyautoxin 5 (GTX5), gonyautoxin 6 (GTX6), and decarbamoyl derivatives, decarbamoyl saxitoxin (dcSTX), decarbamoyl neosaxitoxin (dcNeo) and decarbamoyl gonyautoxin 3 (dcGTX3). In addition, three known hydroxy benzoate derivatives, G. catenatum toxin 1 (GC1), GC2 and GC3, were confirmed in cultured and wild strains of G. catenatum. Moreover, two presumed N-hydroxylated analogues of GC2 and GC3, designated GC5 and GC6, are reported. This work contributes to our understanding of the toxigenicity of G. catenatum in the coastal waters of Portugal and provides valuable information on emerging PST classes that may be relevant for routine monitoring programs tasked with the prevention and control of marine toxins in fish and shellfish.

The cross-cultural adaptation of the Patient-Generated Subjective Global Assessment is important so it can be used with confidence in Portuguese language. To perform a cross-cultural adaptation of the Portuguese version of the Patient-Generated Subjective Global Assessment and to estimate its intrarater reliability. This is a validation study. Face Validity was classified by 17 health professionals and 10 Portuguese language specialists. Idiomatic, semantic, cultural and conceptual equivalences were analyzed. The questionnaire was completed by 20 patients of the Amaral Carvalho Hospital (Jaú, São Paulo, Brazil) in order to verify the Comprehension Index of each item. Therefore, 27 committee members classified each item into "essential", "useful, but not essential" and "not necessary", in order to calculate the Content Validity Ratio. After, this version of the questionnaire was applied twice to 62 patients of the hospital cited above. The intrarater reliability of the nutritional status analyzed by Patient-Generated Subjective Global Assessment was estimated by Kappa statistics. The Portuguese version of the Patient-Generated Subjective Global Assessment presented 10 incomprehensible expressions. The items "a year ago weight" and "dry mouth symptom" presented the lowest Content Validity Ratio. Substantial intrarater reliability (k = 0.78, p = 0.001) was observed. The cross-cultural adaptation of the Portuguese version of the Patient-Generated Subjective Global Assessment became simple and understandable for Brazilian patients. Thus, this version of the Patient-Generated Subjective Global Assessment was considered a valid and a reliable method.

Stigmatizing references to schizophrenia have a negative impact on self-esteem, deter treatment seeking and diminish the effectiveness of treatment. To analyze the reporting of schizophrenia in Portuguese newspapers. We analyzed five high circulation Portuguese newspapers between 2007 and 2013. We selected all news containing the word "esquizofrenia" (schizophrenia). Several variables were collected. About 1058 news items contained the word schizophrenia. Schizophrenia was mentioned metaphorically in 40% of the cases and in the context of Crime in 22%. When used in a Criminal context, schizophrenia was mostly attributed to people who were the perpetrators of the crime (93%). When used metaphorically, schizophrenia had a negative connotation in 90% of cases. We found an increasing reporting of schizophrenia in the criminal news and serious crimes. Our results suggest the media has an active role promoting stigma, as well as passively broadcasting and thus passing on prejudices.

Dyspnoea-12 assesses dyspnea based on the physical and affective components of the symptom. The aim of this study was to translate the Dyspnoea-12 into Portuguese, and to obtain validation data regarding the use of this tool in patients with chronic obstructive lung disease (COPD). The English version of the scale Dyspnoea-12 underwent a formal translation process into Portuguese as spoken in Brazil with the final version being called Dyspnoea-12-Pt. The latter was applied to 51 Portuguese-speaking patients with COPD (33 men; age: 66.4 ± 8.1 years; FEV 1 : 48.7% ± 17.2% pred). Participants also completed the Medical Research Council dyspnea scale (MRC), the Baseline Dyspnea Index (BDI), the Hospital Anxiety and Depression scale, the Saint George's Respiratory Questionnaire (SGRQ) and performed spirometry and the Six-Minute Walk Test (6 MWT). Forty-five volunteers in stable clinical conditions also completed the Dyspnoea-12-Pt scale approximately 2 weeks after the first evaluation. Dyspnoea-12-Pt showed significant correlations with the scales MRC (r = 0.494), BDI (r = -0.511), SGRQ (r = 0.806), Anxiety (r = 0.471), Depression (0.414) and walked distance in the 6 MWT (r = 0.329). Cronbach's alpha of Dyspnoea-12-Pt total was 0.921 and the intraclass correlation coefficient between sequential measures was 0.829. The scale Dyspnoea-12-Pt exhibits acceptable psychometric properties and may be used as an evaluation tool of dyspnea in Portuguese speaking COPD patients. © 2018 John Wiley & Sons Ltd.

Culinary-medicinal honey mushroom or Mi-Huan-Ku, Armillaria mellea (AM), is a popular ingredient in the traditional Chinese medicine for treating diseases of geriatric patients. This study aimed to examine the effect of cultured substrates on the mycelial growth of AM and evaluate its antioxidant and antiedema activities as well as its total polysaccharide and polyphenol contents. Results showed that AM grew best on the maize medium and worst on the potato medium. AM ethanol extract (AM-EtOH) showed stronger DPPH radical scavenging activity than AM aqueous extract (AM-H₂O). However, they were weak in metal chelation and reducing power. AM-EtOH but not AM-H₂O at 200 mg/kg showed antiedema activity in rats. The total β-glucan content of AM-H₂O and AM-EtOH was 21.95% and 3.50%, respectively. AM-EtOH showed higher phenol but lower flavonoid content than AM-H₂O. These results indicate that maize is a good source of substrate for mass production of AM mycelia, and its potency of DPPH radical scavenging and antiedema activities was contributed mainly by the phenolic compounds, not the level of polysaccharide content.

Advances in osteoporosis (OP)case definition, treatment options, optimal therapy duration and pharmacoeconomic evidence in the national context motivated the Portuguese Society of Rheumatology (SPR) to update the Portuguese recommendations for the diagnosis and management of osteoporosis published in 2007. SPR bone diseases' working group organized meetings involving 55 participants (rheumatologists, rheumatology fellows and one OP specialist nurse) to debate and develop the document. First, the working group selected 11 pertinent clinical questions for the diagnosis and management of osteoporosis in standard clinical practice. Then, each question was investigated through literature review and draft recommendations were built through consensus. When insufficient evidence was available, recommendations were based on experts' opinion and on good clinical practice. At two national meetings, the recommendations were discussed and updated. A draft of the recommendations full text was submitted to critical review among the working group and suggestions were incorporated. A final version was circulated among all Portuguese rheumatologists before publication and the level of agreement was anonymously assessed using an online survey. The 2018 SPR recommendations provide comprehensive guidance on osteoporosis prevention, diagnosis, fracture risk assessment, pharmacological treatment initiation, therapy options and duration of treatment, based on the best available evidence. They attained desirable agreement among Portuguese rheumatologists. As more evidence becomes available, periodic revisions will be performed. Target audience and patient population: The target audience for these guidelines includes all clinicians. The target patient population includes adult Portuguese people. Intended use: These recommendations provide general guidance for typical cases. They may not be appropriate in all situations - clinicians are encouraged to consider this information together with

French Influence on Portuguese Architects in the Age of Enlightenment

NASA Astrophysics Data System (ADS)

Sampayo, Mafalda

2017-10-01

This investigation shows the European influence on the work of Portuguese architects of the Enlightenment period. Based on previous studies we focus our attention on the design of “Praça do Comércio” square and on a hypothesis, that it was based on the French Royal Square. We demonstrate that the design of Lisbon from the second half of the eighteenth-century was influenced by the theories and best practices of the time. We also confirm that the architect Eugénio dos Santos e Carvalho, a member of the reconstruction team for the Baixa, had in his personal library several reference books of French architectural practice that certainly influenced his architecture. The plans for the main square of Lisbon’s lower city, “Praça do Comércio”, can be compared to the “Place de Nos Conquêtes”, predecessor of the “Place Vêndome”, in its design, architecture and dimensions. This research analysed the cartography and iconography of Lisbon’s reconstruction. In particular, the drawings of “Praça do Comércio” and “Place de nos Conquêtes” were exhaustively studied. The comparative study of the elements for both squares lead to the conclusion that the Portuguese square presents many aspects of the French Age of Enlightenment, and in particular those featured in the “Place de nos Conquêtes”. This paper concludes that the Portuguese urban design and architectural projects of the 18th century are the result of previous knowledge where it was always possible to articulate the vernacular with academic design, and where many different influences left their mark on the culture of the period. The plans for the lower part of Lisbon display a mixture of references that relate to architectural and urban planning traditions of the Portuguese military engineering and contemporary French urban planning.

The prevalence of obesity has increased worldwide. An assessment of the impact of obesity on health-related quality of life (HRQoL) requires specific instruments. The Moorehead-Ardelt Quality of Life Questionnaire II (MA-II) is a widely used instrument to assess HRQoL in morbidly obese patients. The objective of this study was to translate and validate a Portuguese version of the MA-II.The study included forward and backward translations of the original MA-II. The reliability of the Portuguese MA-II was estimated using the internal consistency and test-retest methods. For validation purposes, the Spearman's rank correlation coefficient was used to evaluate the correlation between the Portuguese MA-II and the Portuguese versions of two other questionnaires, the 36-item Short Form Health Survey (SF-36) and the Impact of Weight on Quality of Life-Lite (IWQOL-Lite).One hundred and fifty morbidly obese patients were randomly assigned to test the reliability and validity of the Portuguese MA-II. Good internal consistency was demonstrated by a Cronbach's alpha coefficient of 0.80, and a very good agreement in terms of test-retest reliability was recorded, with an overall intraclass correlation coefficient (ICC) of 0.88. The total sums of MA-II scores and each item of MA-II were significantly correlated with all domains of SF-36 and IWQOL-Lite. A statistically significant negative correlation was found between the MA-II total score and BMI. Moreover, age, gender and surgical status were independent predictors of MA-II total score.A reliable and valid Portuguese version of the MA-II was produced, thus enabling the routine use of MA-II in the morbidly obese Portuguese population.

The main objective of this work consisted of the updating of allele frequencies and other relevant forensic parameters for the 17 autosomal STR loci provided by the combination of the two types of kits used routinely in our laboratory casework: AmpF/STR Identifiler(®) and the Powerplex(®) 16 Systems. This aim was of significant importance, given that the last study on these kits within the southern Portuguese population dates back to 2006, and, as a consequence, it was necessary to correct the deviation caused by population evolution over the last ten years so that they might be better applied to our forensic casework. For this reason genetic data from 5362 unrelated Caucasian Portuguese individuals from the south of Portugal who were involved in paternity testing casework from 2005 to 2014 was used. Of all the markers, TPOX proved to be the least polymorphic, and Penta E the most. Secondly, this up-to-date southern Portuguese population was compared not only with the northern and central Portuguese populations, but also with that of southern Portugal in 2006, along with populations from Spain, Italy, Greece, Romania, Morocco, Angola and Korea in order to infer information about the relatedness of these respective populations, and the variation of the southern Portuguese population over time.

[Dengue fever in Portuguese speaking countries: which epidemiological links may we set?].

PubMed

Silvano, José; Abreu, Cândida

2014-01-01

The recent occurrence of a number of outbreaks of dengue in Portuguese speaking countries with no previous disease, aroused curiosity about the competing factors for the phenomenon and a need for better knowledge of the pathology. We review the dengue-related situation in Portuguese speaking countries, linking the various outbreaks and trying to contribute to a better understanding of the phenomenon. Review of the literature on the topic and relevant information obtained from oral communications were included. The outbreaks occurred between the years of 2009 and 2013 in Cabo Verde, Madeira and Angola (excluding the endemic phenomenon in Brazil), share the same vector Aedes aegypti, but are due to different viral serotypes, as shown by genotypic studies. The strong sub-notification of the disease in Africa and lack of diagnostic tools prevent a true characterization of the situation. The hypothesis of a link between some of the outbreaks is not completely rejected. The Portuguese territory could be exposed to an increasingly high risk of dengue introduction, not only because of the proximity with these territories, but also because of the current climate changes. The main fight is, in spite of the still elusive emergent tools, the vector control. A link between the outbreaks has not been proven but local preparation of healthcare professionals, creation of public health strategies and maintenance of surveillance systems are needed. More epidemiological and entomological studies are needed to characterize the real incidence of disease in Portuguese speaking countries.

2010-11-01

The harmonisation of food composition databases (FCDB) has been a recognised need among users, producers and stakeholders of food composition data (FCD). To reach harmonisation of FCDBs among the national compiler partners, the European Food Information Resource (EuroFIR) Network of Excellence set up a series of guidelines and quality requirements, together with recommendations to implement quality management systems (QMS) in FCDBs. The Portuguese National Institute of Health (INSA) is the national FCDB compiler in Portugal and is also a EuroFIR partner. INSA's QMS complies with ISO/IEC (International Organization for Standardisation/International Electrotechnical Commission) 17025 requirements. The purpose of this work is to report on the strategy used and progress made for extending INSA's QMS to the Portuguese FCDB in alignment with EuroFIR guidelines. A stepwise approach was used to extend INSA's QMS to the Portuguese FCDB. The approach included selection of reference standards and guides and the collection of relevant quality documents directly or indirectly related to the compilation process; selection of the adequate quality requirements; assessment of adequacy and level of requirement implementation in the current INSA's QMS; implementation of the selected requirements; and EuroFIR's preassessment 'pilot' auditing. The strategy used to design and implement the extension of INSA's QMS to the Portuguese FCDB is reported in this paper. The QMS elements have been established by consensus. ISO/IEC 17025 management requirements (except 4.5) and 5.2 technical requirements, as well as all EuroFIR requirements (including technical guidelines, FCD compilation flowchart and standard operating procedures), have been selected for implementation. The results indicate that the quality management requirements of ISO/IEC 17025 in place in INSA fit the needs for document control, audits, contract review, non-conformity work and corrective actions, and users' (customers

Cultural competence in mental health nursing: validity and internal consistency of the Portuguese version of the multicultural mental health awareness scale-MMHAS.

Cultural competence is an essential component in rendering effective and culturally responsive services to culturally and ethnically diverse clients. Still, great difficulty exists in assessing the cultural competence of mental health nurses. There are no Portuguese validated measurement instruments to assess cultural competence in mental health nurses. This paper reports a study testing the reliability and validity of the Portuguese version of the Multicultural Mental Health Awareness Scale-MMHAS in a sample of Portuguese nurses. Following a standard forward/backward translation into Portuguese, the adapted version of MMHAS, along with a sociodemographic questionnaire, were applied to a sample of 306 Portuguese nurses (299 males, 77 females; ages 21-68 years, M = 35.43, SD = 9.85 years). A psychometric research design was used with content and construct validity and reliability. Reliability was assessed using internal consistency and item-total correlations. Construct validity was determined using factor analysis. The factor analysis confirmed that the Portuguese version of MMHAS has a three-factor structure of multicultural competencies (Awareness, Knowledge, and Skills) explaining 59.51% of the total variance. Strong content validity and reliability correlations were demonstrated. The Portuguese version of MMHAS has a strong internal consistency, with a Cronbach's alpha of 0.958 for the total scale. The results supported the construct validity and reliability of the Portuguese version of MMHAS, proving that is a reliable and valid measure of multicultural counselling competencies in mental health nursing. The MMHAS Portuguese version can be used to evaluate the effectiveness of multicultural competency training programs in Portuguese-speaking mental health nurses. The scale can also be a useful in future studies of multicultural competencies in Portuguese-speaking nurses.

This study analyzed the crustacean diversity, distribution and relationship with environmental factors in the western and the southern Portuguese continental shelf, between 10 and 200 m depth. A total of 10,639 specimens belonging to 242 taxa from 90 families were identified, mostly amphipods (55.8% of the total taxa). The mysid Gastrosaccus spinifer and the amphipods Socarnes erythrophthalmus and Cheirocratus sundevallii were the most abundant and the amphipods Ampelisca brevicornis, Leucothoe incisa and Autonoe spiniventris were the most frequent species. The highest abundance and diversity was found in coarser sediments with up to 306 individuals per 0.1 m2. Alpha diversity ranged from 1 to 28 sp./0.1 m2. Moreover, this study confirmed six previously doubtful first records and added an additional 19 new records to the Portuguese fauna. The results also confirmed the Portuguese coast as a transition zone of mixed Atlantic and Mediterranean faunas and exposed a noticeable North African and Macaronesian influence. A multivariate analysis based on the abundance of crustaceans revealed six affinity groups characterized by: (a) C. sundevallii, Guernea (Guernea) coalita and Sarsinebalia cristoboi on very coarse sands; (b) G. spinifer, Nototropis falcatus and Pontocrates arenarius on coarse sands; (c) Othomaera othonis, Processa modica modica and Animoceradocus semiserratus on heterogeneous medium sands; (d) A. brevicornis, Urothoe pulchella and Necalianassa truncata on fine sands; (e) Ampelisca pectenata, Bodotria scorpioides and Astacilla dilatata on heterogeneous fine sands and (f) Callianassa subterranea, Ampelisca tenuicornis and Ampelisca typica on muddy fine sands. Sediment grain-size and depth were the variables best related to the benthic crustacean spatial distribution patterns along the Portuguese continental shelf.

The EQ-5D allows the achievement of two essential components of any measure of health-related quality of life to be used in cost-utility economic evaluations: (i) a profile describing the health status in terms of domains or dimensions; and (ii) a numeric value associated with the health status described. The Portuguese version of the EQ-5D questionnaire was completed in 1998, based on guidelines set by the EuroQol Group, including translation and back translation procedures. Despite its wide use in Portugal, until now it had not yet been published studies that initially led to the Portuguese version and the guarantee of acceptability, reliability and validity. The purpose of this article is to document these first values relating to the Portuguese version of the EQ-5D. We used three different samples: a first one with 1,500 individuals representative of the Portuguese population; a second with 140 individuals just intended for the reliability test; and a third sample with 643 individual patients with cataracts, asthma, chronic obstructive pulmonary disease, or rheumatoid arthritis. The acceptability was assessed by the number of missing responses. It was also found a marked ceiling effect, with a large part of the sample not reporting any problems in the dimensions of the EQ-5D. The construct validity was tested by examining the degree to which low values of EQ-5D were positively associated with increasing age, being female, and the sick, as well as the values of dimensions of the SF-36v2 scale. Convergent validity was based on correlations between EQ-5D values and other specific measures. The EQ-5D showed moderate to high correlations with other disease-specific measures of health status and health related quality of life. We can state that the Portuguese version of the EQ-5D has a good accessibility, reliability and validity in measuring health.

To translate the Munich Music Questionnaire (MUMU) to Brazilian Portuguese, to adapt it culturally, and to describe the results obtained among adult users of cochlear implant (CI). We translated the questionnaire to Brazilian Portuguese, reviewed the grammatical and idiomatic equivalences (back-translation), and adapted it from a linguistic and cultural perspective. The resulting version of this process was applied among adult CI users through direct interviews. The Brazilian Portuguese version of MUMU was applied to 19 adult CI users with postlingual hearing loss, who had been users of the device for at least one year. The answers to the questionnaire were analyzed by distribution of frequency and percentage of occurrence in each question. The results showed a decrease in the frequency of CI users that listen to music, comparing the period before hearing loss and after the CI. Regarding the role that music played in the life of each participant, the responses did not score change, so the music remained being an important factor in the life of the evaluated subjects, even after the CI. The subjective evaluation tool MUMU was translated and culturally adapted to the population studied. In Brazilian Portuguese, it was called Questionário de Música de Munique. The study showed its applicability in the daily monitoring of CI users, thus providing a profile of the activities related to music in everyday life.

OBJECTIVE: To validate a Portuguese-language version of the COPD assessment test (CAT) for use in Brazil and to assess the reproducibility of this version. METHODS: This was multicenter study involving patients with stable COPD at two teaching hospitals in the city of Fortaleza, Brazil. Two independent observers (twice in one day) administered the Portuguese-language version of the CAT to 50 patients with COPD. One of those observers again administered the scale to the same patients one week later. At baseline, the patients were submitted to pulmonary function testing and the six-minute walk test (6MWT), as well as completing the previously validated Portuguese-language versions of the Saint George's Respiratory Questionnaire (SGRQ), modified Medical Research Council (MMRC) dyspnea scale, and hospital anxiety and depression scale (HADS). RESULTS: Inter-rater and intra-rater reliability was excellent (intraclass correlation coefficient [ICC] = 0.96; 95% CI: 0.93-0.97; p < 0.001; and ICC = 0.98; 95% CI: 0.96-0.98; p < 0.001, respectively). Bland Altman plots showed good test-retest reliability. The CAT total score correlated significantly with spirometry results, 6MWT distance, SGRQ scores, MMRC dyspnea scale scores, and HADS-depression scores. CONCLUSIONS: The Portuguese-language version of the CAT is a valid, reproducible, and reliable instrument for evaluating patients with COPD in Brazil. PMID:24068260

This article seeks to redeem the historical memory of a health institution in Portugal which reconfigured itself and adapted to the social and medical needs and concerns during the twentieth century. The trajectory of this institution contributes to the history of Portuguese medicine and to the history of the philanthropy of the Portuguese colony resident in Brazil and the so called "Brazilians" that returned to Portugal, whose remittances provided the means to set up a benchmark health institution in the twenty-first century. The methodology was based on archival research in Portugal (Coimbra, Bissaya Barreto Foundation) and in Brazil (Rio de Janeiro, Real Gabinete Português de Leitura) and the cross-checking of these primary sources with due historical and social contextualization.

This paper reports data on bioconcentration potential and baseline mercury concentrations of fruiting bodies of dark honey fungus (Armillaria solidipes) Peck and soil substrate layer (0-10 cm) from 12 spatially distant sites across Poland. Mercury content of caps, stipes and soil samples were determined using validated analytical procedure including cold-vapor atomic absorption spectroscopy after thermal decomposition of the sample matrix and further amalgamation and desorption of mercury from gold wool. Mean mercury concentrations ranged from 20 ± 8 to 300 ± 70 ng g(-1) dry weight (dw) in caps, from 20 ± 6 to 160 ± 40 ng g(-1) dw in stipes, and in underlying soil were from 20 ± 2 to 100 ± 130 ng g(-1) dw. The results showed that stipes mercury concentrations were 1.1- to 1.7-fold lower than those of caps. All caps and the majority of stipes were characterized by bioconcentration factor values > 1, indicating that dark honey fungus can be characterized as a moderate mercury accumulator. Occasional or relatively frequent eating of meals including caps of dark honey fungus is considered safe in view of the low total mercury content, and the mercury intake rates are below the current reference dose and provisionally tolerable weekly intake limits for this hazardous metal. © 2012 Society of Chemical Industry.

Psoriatic arthritis (PsA) has a strong negative impact on the quality of life of patients. The Psoriatic Arthritis Quality of Life (PsAQoL) questionnaire is a disease-specific instrument developed to measure the quality of life in patients with PsA. The aims of this study were to culturally adapt the questionnaire for Portugal and evaluate its reliability and validity in patients with PsA. The original UK English version of the PsAQoL was translated into Portuguese by a bilingual and lay panel. Structured cognitive debriefing interviews were conducted with ten PsA patients. The Portuguese PsAQoL was subsequently applied to PsA patients followed at the Rheumatology Department of Centro Hospitalar do Baixo Vouga, E.P.E. To assess reproducibility, 30 patients with PsA completed the Portuguese PsAQoL on two occasions, 2 weeks apart. A larger sample was recruited to determine internal consistency and construct validity. The Nottingham Health Profile (NHP) was used as a comparator instrument. Translation and adaptation were successful. Cronbach´s alpha for the Portuguese version of the PsAQoL was 0.91 and the test-retest reliability was 0.93. The PsAQoL could distinguish between groups of patients defined by self-reported general health status, self-reported severity of PsA and flare of arthritis. There was a positive correlation between the total score of the PsAQoL and each of the sections of the NHP. The Portuguese version of the PsAQoL was found to be relevant, understandable and easy to complete, reliable and valid.

The aim of the present study was to examine the psychometric properties of the Youth Psychopathic Traits Inventory (YPI) among a mixed-gender sample of 782 Portuguese youth (M = 15.87 years; SD = 1.72), in a school context. Confirmatory factor analysis revealed the expected three-factor first-order structure. Cross-gender measurement invariance and cross-sample measurement invariance using a forensic sample of institutionalized males were also confirmed. The Portuguese version of the YPI demonstrated generally adequate psychometric properties of internal consistency, mean inter-item correlation, convergent validity, discriminant validity, and criterion-related validity of statistically significant associations with conduct disorder symptoms, alcohol abuse, drug use, and unprotected sex. In terms of known-groups validity, males scored higher than females, and males from the school sample scored lower than institutionalized males. The use of the YPI among the Portuguese male and female youth population is psychometrically justified, and it can be a useful measure to identify adolescents with high levels of psychopathic traits.

Organa magazine (1990-1992) is the first known lesbian publication in Portugal and exemplifies the distinct course of lesbian activism in Portugal, namely the late emergence and consolidation of a national lesbian community and subculture. Organa also bears similarities with the international gay and lesbian press regarding its alternative character, objectives, editorial contents, and trajectory. Despite having adopted an assimilationist strategy during most of its existence, it is argued that Organa fostered the political mobilization of Portuguese lesbians.

Portuguese agriculture and the evolution of greenhouse gas emissions-can vegetables control livestock emissions?

PubMed

Mourao, Paulo Reis; Domingues Martinho, Vítor

2017-07-01

One of the most serious externalities of agricultural activity relates to greenhouse gas emissions. This work tests this relationship for the Portuguese case by examining data compiled since 1961. Employing cointegration techniques and vector error correction models (VECMs), we conclude that the evolution of the most representative vegetables and fruits in Portuguese production are associated with higher controls on the evolution of greenhouse gas emissions. Reversely, the evolution of the output levels of livestock and the most representative animal production have significantly increased the level of CO 2 (carbon dioxide) reported in Portugal. We also analyze the cycle length of the long-term relationship between agricultural activity and greenhouse gas emissions. In particular, we highlight the case of synthetic fertilizers, whose values of CO 2 have quickly risen due to changes in Portuguese vegetables, fruit, and animal production levels.

2013-05-01

Cork forest systems are responsible for making an important economic contribution to the Mediterranean region, especially Portugal where the cork oak woodlands or montados contain about 32% of the world's area. The environmental profile derived from reproduction cork production and extraction in two Portuguese regions (Tagus valley and Alentejo) representative of the Portuguese sector were assessed in detail using the Life-Cycle Assessment (LCA) methodology from a cradle-to-gate perspective. The production line was divided into four stages considering all the processes involved: stand establishment, stand management, cork stripping and field recovery. According to the environmental results, there were remarkable differences between the two production scenarios mainly due to the intensity and repetition of forest activities even though the cork yield was reported to be the same. The management system in the Alentejo region presented the worse environmental profile in almost all the impact categories under assessment, mainly due to the shorter cycle duration of the mechanical cleaning and pruning processes. Cork stripping was identified in both scenarios as the production stage with the highest contribution to the environmental profile due to the cleaning and pruning processes. A sensitivity assessment concerning the cork yield was performed since the average production yields in the Portuguese montados are lower than the ones used in this study. Thus, if the cork yield is reduced, the environmental profile in both scenarios gets worse since almost all the forest activities involved are the same. Copyright © 2013 Elsevier B.V.

Good oral health is essential for good general health and quality of life. In Portugal, there are few studies on oral-health habits and the population's perceptions of this behaviour. The main purpose of this study was to characterise the Portuguese population's self-reported oral-health status, habits and perceptions, as well as their demands regarding national oral health-care services. A randomised group of 1,395 individuals, > 15 years of age, was selected as a representative sample of the Portuguese population. Face-to-face interviews were conducted, based on a structured questionnaire with closed and semi-closed questions. The data were submitted for statistical analysis using SPSS. A sample of 1,102 individuals answered the questionnaire. The great majority of the sample (97.6%) brushed their teeth daily, 70.3% had lost permanent teeth and 6.4% were edentulous. The loss of permanent teeth was statistically associated with poor oral-hygiene habits (P < 0.01). Moreover, 50.1% of the participants had experienced difficulty eating and/or drinking, 18% had felt ashamed of the appearance of their teeth and 69.3% had experienced toothache or gingival pain. A reduction in visits to a dentist in the previous 12 months was identified mainly for people from a lower social class (31.2%) and older people (29.4%). Evidence suggests that oral diseases might be more prevalent in Portuguese adults than the European average. Efforts should be made to promote good oral-hygiene habits among older people and people from lower social classes. © 2016 FDI World Dental Federation.

The objective of the present study was to analyze the role of psychopathic traits in juvenile delinquency. Using a sample of 543 young males from the Juvenile Detention Centers of the Portuguese Ministry of Justice and from schools in the Lisbon region, a group of high psychopathic traits (n = 281) and a group of low psychopathic traits (n = 262) were formed based on the Portuguese version of Antisocial Process Screening Device (APSD). Results showed that youths with high psychopathic traits start engaging in criminal activities earlier in life, come into contact with the justice system earlier in life, and have higher levels of conduct disorder, behavior problems, and delinquent behaviors as well as lower levels of self-esteem.

Portugal is the country with the largest EEZ in the EU and the 10th largest EEZ in the world, at 3,877,408 km2, rendering the existence of an integrated management of Portuguese marine system crucial to monitor a wide range of interdependent domains. A system like this assimilates data and information from different thematic areas, ranging from ocean and atmosphere state variables to higher level datasets describing human activities and related environmental, social and economic impacts. Currently, these datasets are collected by a wide number of public and private institutions with very diverse purposes (e.g., monitoring, research, recreation, vigilance) leading to dataset duplication, inexistence of common data and metadata standards across organizations, and the propagation of closed information systems with different implementation solutions. This lack of coordination and visibility hinders the marine management, monitoring and vigilance capabilities, not only by making it more difficult to access, or even be aware of, the existence of certain datasets, but also by minimizing the ability to create added value products or services through dataset integration from different sources. Adopting Open Data approach will bring significant benefits by reducing the cost of information exchange and data integration, promoting the extensive use of this data. SIMOcean (System for Integrated Monitoring of the Ocean), co-funded by the EEA Grants Programme, is integrated in the initiative of the Portuguese Government to develop a set of coordinated systems providing access to national marine data. These systems aim to improve the Portuguese marine management, monitoring and vigilance capabilities, aggregating different data, including specific human activities datasets (vessel traffic, fishing records, oil spills), and environment variables (waves, currents, wind).

2013-01-01

Chitotriosidase is an enzyme secreted by activated macrophages and a useful biomarker in several lysosomal and nonlysosomal diseases. However, chitotriosidase gene (CHIT1) mutations may lead to inaccuracy in the significance of this biomarker. Reports on the molecular spectrum of genetic variation in chitotriosidase are rare, and this is one of the few that focus on a specific population group. In this work we assessed the variation of CHIT1 mutations in ten normal controls and detected six missense alterations. G102S, a polymorphism with known altered catalytic properties, was the most frequent being detected in 4/10 individuals. Using allelic discrimination we tested 503 individuals, randomly sampled from the Portuguese population. Variant G102S was detected in 49.5% of the individuals and presented an allele frequency of 0.29. The results of this study showed that variability in CHIT1 gene is considerable and that G102S polymorphism presents a high frequency in the Portuguese. Copyright © 2012 Elsevier Inc.

The Alzheimer's Disease Assessment Scale - Cognitive Subscale is a brief battery developed to assess cognitive functioning in Alzheimer's disease that encompasses the core characteristics of cognitive decline (e.g. memory, language, praxis, constructive ability and orientation). The early detection, as well as the monitoring of cognitive decline along disease progression, is extremely important in clinical care and interventional research. The main goals of the present study were to analyze the psychometric properties of the Portuguese version of the Alzheimer's Disease Assessment Scale - Cognitive Subscale, and to establish normative values for the Portuguese population. The Portuguese version of Alzheimer's Disease Assessment Scale - Cognitive Subscale was administered to 223 cognitively healthy participants according to a standard assessment protocol consisting of the Mini-Mental State Examination, the Montreal Cognitive Assessment and the Adults and Older Adults Functional Assessment Inventory. Normal performance on the assessment protocol was the inclusion criteria for the study. The Alzheimer's Disease Assessment Scale - Cognitive Subscale revealed good psychometric properties when used in the Portuguese population. Age was the main predictor of the Alzheimer's Disease Assessment Scale - Cognitive Subscale total score (R2 = 0.123), whereas the influence of education level was lower (R2 = 0.027). These two variables explained 14.4% of the variance on the Alzheimer's Disease Assessment Scale - Cognitive Subscale scores and were used to stratify the normative values for the Portuguese population presented here. On the total sample, the average total score in the Alzheimer's Disease Assessment Scale - Cognitive Subscale was 6 points. The normative data were determined according to age and educational level as these were the sociodemographic variables that significantly contributed to the prediction of the Alzheimer's Disease Assessment Scale - Cognitive Subscale

Tuberculosis is a major health problem in Portugal. To begin characterizing the population structure of Mycobacterium tuberculosis, spoligotyping was used for the systematic typing, through consecutive sampling, of patient isolates from the Amadora-Sintra area of Greater Lisbon. Distribution amongst major spoligotype families, including the Latin American Mediterranean (LAM), T, Haarlem and Beijing, was compared to that of the international spoligotype database SpolDB4 and to the European countries of traditional Portuguese immigration represented in SpolDB4. Spoligotypes from 665 isolates were analyzed and 97 shared international types (SITs) identified. In SpolDB4 Portugal is represented by part of the spoligotypes from this study explaining the reduced number of unidentified patterns. The importance of the LAM family, and especially of LAM1 and LAM9 sub-families that alone represented 38% of all the isolates in this study as compared to 8% relative to the European sub group, led us to believe that at least in this respect the population structure was closer to that of Africa and South America than to Europe. Spoligotypes characteristic of Portugal or Portuguese related settings were identified. These included SIT244 a T1 sub-family predominant in Portugal and Bangladesh, SIT64 a LAM 6 sub-family common to Portugal and Brazil, and SIT1106 a LAM 9 sub-family. These studies were the first in Portugal stressing the importance of monitoring the population structure of M. tuberculosis isolates, an important step towards gaining an understanding of tuberculosis and the dynamics of this disease.

Eating disorders are an increasingly prevalent health problem among adolescent girls. It is well known that biological, psychosocial, and family-related factors interact in the development of this group of disorders. However, the mechanisms underlying the interaction between these variables are still poorly understood, especially in Portuguese adolescents. The aim of this study was to investigate the relationship between eating behaviors, body dissatisfaction, self-esteem, and perfectionism in a sample of Portuguese girls. A community sample of 575 Portuguese girls attending secondary school, answered self-report questionnaires including data on weight, height, and the Portuguese versions of the Contour Figures Rating Scale, the Child and Adolescent Perfectionism Scale, the Children Eating Attitudes Test, and the Rosenberg Self-Esteem Scale. SPSS version 20.0 for Windows was used for statistical analyses. High scores in the Children Eating Attitudes Test were associated with significantly higher levels of body dissatisfaction (r = 0.339), socially prescribed perfectionism (r = 0.175), self-oriented perfectionism (r = 0.211), and low self-esteem (r = -0.292) (all p < 0.001). Self-oriented perfectionism partially mediated the relation between body dissatisfaction and disordered eating behaviors. In this sample, dysfunctional eating behaviors appeared to correlate strongly with body dissatisfaction, low self-esteem, and perfectionism in girls. These themes should be addressed among female adolescents in the community.

To initiate the characterization of the Portuguese grapevine genepool, we have genotyped 49 Portuguese grapevine cultivars at 11 microsatellite loci. The markers proved to be informative in the Portuguese cultivars, with expected heterozygosity ranging from 0.67 to 0.84. At most loci, an excess of heterozygous individuals was observed, while the deficiency of heterozygotes at 1 locus (VVMD6) indicated the presence of null alleles. On the basis of the microsatellite allele data several previously assumed synonyms were verified: (1) 'Fernão Pires'='Maria Gomes', (2) 'Moscatel de Setúbal'='Muscat of Alexandria', (3) 'Boal Cachudo'='Boal da Madeira'='Malvasia Fina', (4) 'Síria'='Crato Branco'= 'Roupeiro' and (5) 'Periquita'='Castelão Francês'='João de Santarém'='Trincadeira'. Although the three varieties 'Verdelho da Madeira', 'Verdelho dos Açores', and 'Verdelho roxo' are regarded by the Lista Nacional de Sinónimos as distinct cultivars, they displayed identical SSR profiles at 17 loci and appear to represent types of 1 single cultivar. The genetic profiles of all 49 cultivars were searched for possible parent-offspring groups. The data obtained revealed the descendence of 'Boal Ratinho' from 'Malvasia Fina' and 'Síria'.

2016-09-01

This study aims to describe the size distribution of Portuguese firms, as measured by annual sales and total assets, between 2006 and 2012, giving an economic interpretation for the evolution of the distribution along the time. Three distributions are fitted to data: the lognormal, the Pareto (and as a particular case Zipf) and the Simplified Canonical Law (SCL). We present the main arguments found in literature to justify the use of distributions and emphasize the interpretation of SCL coefficients. Methods of estimation include Maximum Likelihood, modified Ordinary Least Squares in log-log scale and Nonlinear Least Squares considering the Levenberg-Marquardt algorithm. When applying these approaches to Portuguese's firms data, we analyze if the evolution of estimated parameters in both lognormal power and SCL is in accordance with the known existence of a recession period after 2008. This is confirmed for sales but not for assets, leading to the conclusion that the first variable is a best proxy for firm size.

[The new face of Portuguese medicine: the generation of 1911 and the research school of Marck Athias].

PubMed

Amaral, Isabel Maria

2011-01-01

This paper aims to demonstrate that with Marck Athias, the Portuguese medicine inaugurated a new chapter in its history, in the Republic period, characterized by the experimental training at the laboratory. Thus, book-based knowledge gave way to a more clinically based approach favouring laboratory practice and basic research within several scientific domains. This new perspective operated important changes in the Portuguese medical community in the first half of century XX. Marck Athias (1857-1946), a Portuguese, was a physician trained at the University of Paris under Mathias Duval (a former student of Santiago Rámon y Cajal). It was in his laboratory that Athias began his career as researcher. Returning to Portugal, Athias founded a research school in physiology and histology which stressed a new approach in medicine based on experimental research. At the beginning of the twentieth century, scientific research in Portugal was virtually devoid of any of the practical clinic aspects. It is in fact Athias who introduced a new scientific perspective in Portuguese scientific community as well as influenced generations of graduate students in several national higher education and scientific research centres associated with Medicine. His influence and impact was due in great part to the underlying ideology of a positivist nature which succeeded in attracting several generations of followers, promoting a new step for the modernization of Portuguese medicine.

Objective To adapt and validate a widely used set of moral dilemmas to European Portuguese, which can be applied to assess decision-making. Moreover, the classical formulation of the dilemmas was compared with a more focused moral probe. Finally, a shorter version of the moral scenarios was tested. Methods The Portuguese version of the set of moral dilemmas was tested in 53 individuals from several regions of Portugal. In a second study, an alternative way of questioning on moral dilemmas was tested in 41 participants. Finally, the shorter version of the moral dilemmas was tested in 137 individuals. Results Results evidenced no significant differences between English and Portuguese versions. Also, asking whether actions are "morally acceptable" elicited less utilitarian responses than the original question, although without reaching statistical significance. Finally, all tested versions of moral dilemmas exhibited the same pattern of responses, suggesting that the fundamental elements to the moral decision-making were preserved. Conclusions We found evidence of cross-cultural validity for moral dilemmas. However, the moral focus might affect utilitarian/deontological judgments.

Defending metropolitan identity through colonial politics: The role of Portuguese naturalists (1870-91).

PubMed

Gamito-Marques, Daniel

2018-06-01

This paper explores how João de Andrade Corvo and José Vicente Barbosa du Bocage, two nineteenth-century Portuguese naturalists, were able to reach prominent political positions in their country by means of their work in, respectively, botany and agriculture, and zoology. The authority they derived from their scientific activities and the knowledge they acquired in the process, favored by their proximity to particular political quarters, elevated them to important governmental offices, in the context of which they implemented policies that reinforced Portugal's identity as an imperial nation. The colonial policies and agreements signed by Corvo and Bocage aimed at securing Portuguese colonial territories, which, aside from their economic relevance, constituted a symbol of power that reinforced the sovereignty of a small nation in a Europe dominated by the rule of increasingly vaster and stronger states. In spite of their different scientific careers and personal interests, both naturalists played key roles in Portuguese foreign affairs and colonial negotiations of the late nineteenth century, especially during the Scramble for Africa.

It is well known that papers written in languages other than English have a great risk of being ignored simply because these languages are not accessible to the international scientific community. The objective of this paper is to facilitate the access to the public health and epidemiology literature available in Portuguese speaking countries. It was found that it is particularly concentrated in Brazil, with some few examples in Portugal and none in other Portuguese speaking countries. This literature is predominantly written in Portuguese, but also in other languages such as English or Spanish. The paper describes the several journals, as well as the bibliographic databases that index these journals and how to access them. Most journals provide open-access with direct links in the indexing databases. The importance of this scientific production for the development of epidemiology as a scientific discipline and as a basic discipline for public health practice is discussed. To marginalize these publications has implications for a more balanced knowledge and understanding of the health problems and their determinants at a world-wide level. PMID:18826592

2016-01-01

Proanthocyanidins (PAs) are one of the most important polyphenolic compounds in wine. Among PAs, prodelphinidin (PD) dimers and trimers have not been widely detected in wines due to the lack of available commercial standards and the difficulty to detect and isolate them from natural sources. LC-ESI-MS (liquid chromatography-electrospray ionization-mass spectrometry) with the right chromatographic conditions has proven to be a powerful tool for PAs detection and identification in complex samples. This technique has been applied to an exhaustive study of PA composition of two Portuguese red wines made with teinturier grapes, especially for the identification of PD dimers and trimers. Tandem mass spectrometry (MS/MS) with ion trap provided additional information about the structures of these compounds through the fragmentation patterns of the pseudomolecular ions. A LC-ESI-MS method was optimized and 41 different compounds were found. Among them are included 8 PD dimers and 13 PD trimers. Copyright © 2015 Elsevier Ltd. All rights reserved.

Undergraduate Teaching in Geriatrics and Pediatrics in Portuguese Medical Schools: An Observational Study.

2016-12-30

Motivated by the contracting nature of the Portuguese age pyramid, and thereby the ever increasing geriatric population, the aim of this study was to compare the number of European Credit Transfer and Accumulation System Credits dedicated to Geriatrics with Pediatrics in Portuguese Medical Schools. An observational, descriptive and cross-sectional study was conducted and included six Portuguese Medical Schools that have six years of training and a total of 360 credits. The study plans were obtained from the medical schools' websites or requested. Schools were grouped in modular/classic teaching methodology and the courses were categorized in mandatory/optional and specific/related. The credits of Geriatrics and Pediatrics were compared. Four schools had classical methodology and two had a modular one. Overall, they had more credits dedicated to Pediatrics than Geriatrics. Three schools offered mandatory courses specifically oriented to Geriatrics (1.5 - 8 credits) compared to all schools mandatory courses courses on Pediatrics (5.7 - 26.5 credits). The ratio of averages of mandatory specific courses (Pediatrics/Geriatrics) was 12.4 in the classical and 1.5 in the modular group. Pediatrics teaching has revealed to be superior to Geriatrics in all categories. Based on our results, we consider the Portuguese Geriatrics' undergraduate teaching sub-optimal. Nowadays, geriatric population is quantitatively similar to pediatric population. Efforts should be made to adequate Geriatrics teaching to our reality in order to provide a more adequate health care to this age group.

The PTSD Checklist-Military Version (PCL-M) is a brief self-report instrument widely used to assess Post-traumatic Stress Disorder (PTSD) symptomatology in war Veterans, according to DSM-IV. This study sought out to explore the factor structure and reliability of the Portuguese version of the PCL-M. A sample of 660 Portuguese Colonial War Veterans completed the PCL-M. Several Confirmatory Factor Analyses were conducted to test different structures for PCL-M PTSD symptoms. Although the respecified first-order four-factor model based on King et al.'s model showed the best fit to the data, the respecified first and second-order models based on the DSM-IV symptom clusters also presented an acceptable fit. In addition, the PCL-M showed adequate reliability. The Portuguese version of the PCL-M is thus a valid and reliable measure to assess the severity of PTSD symptoms as described in DSM-IV. Its use with Portuguese Colonial War Veterans may ease screening of possible PTSD cases, promote more suitable treatment planning, and enable monitoring of therapeutic outcomes.

Patients and their relatives often look for information about their diseases on the internet. Diabetes mellitus (DM), systemic arterial hypertension (SAH), and acute myocardial infarction (AMI) are the most prevalent in Brazil, thus, information on these pathologies is extremely searched for on the internet. For this reason, this study attempted to evaluate the quality of information available in Portuguese on the web regarding these disorders. The first 20 websites in Portuguese for each disease through the Google® search algorithm were selected. The Discern Questionnaire (DQ) and Health on the Net (HON) were used as tools in order to evaluate the quality of information. To assess adequacy, international and Brazilian guidelines for different co-morbidities were used. When evaluating the information content available, 45%, 95%, and 85% of pages had the definition of DM, SAH, and AMI, respectively. Only 25% of the websites regarding the three co-morbidities had specific information on diagnosis and treatment. Only 15%, 20%, and 10% of the websites had HON certification, respectively. Using the DQ approach, scores higher than 50% were obtained in 70% of the DM websites, in 65% of SAH websites, and in 55% of the AMI websites. The available information in Portuguese on the internet regarding the three pathologies selected (DM, SAH, and AMI) is quite often inadequate and insufficient.

SLC26A2-related dysplasias encompass a spectrum of diseases: from lethal achondrogenesis type 1B (ACG1B; MIM #600972) and atelosteogenesis type 2 (AO2; MIM #256050) to classical diastrophic dysplasia (cDTD; MIM #222600) and recessive multiple epiphyseal dysplasia (rMED; MIM #226900). This study aimed at characterizing clinically, radiologically and molecularly 14 patients affected by non-lethal SLC26A2-related dysplasias and at evaluating genotype-phenotype correlation. Phenotypically, eight patients were classified as cDTD, four patients as rMED and two patients had an intermediate phenotype (mild DTD - mDTD, previously 'DTD variant'). The Arg279Trp mutation was present in all patients, either in homozygosity (resulting in rMED) or in compound heterozygosity with the known severe alleles Arg178Ter or Asn425Asp (resulting in DTD) or with the mutation c.727-1G>C (causing mDTD). The 'Finnish mutation', c.-26+2T>C, and the p.Cys653Ser, both frequent mutations in non-Portuguese populations, were not identified in any of the patients of our cohort and are probably very rare in the Portuguese population. A targeted mutation analysis for p.Arg279Trp and p.Arg178Ter in the Portuguese population allows the identification of approximately 90% of the pathogenic alleles. © 2010 John Wiley & Sons A/S.

Butcher shops are end points in the meat chain, and they can have a determinant role in cross-contamination control. This study aims to determine whether Portuguese butcher shops comply with European and Portuguese law regarding the sale of fresh meat and meat products. Butcher shops (n = 73) were assessed for meat handler and facility hygiene and for maintenance of the premises. Handlers (n = 88) were given a questionnaire composed of questions about knowledge and practice, including hazard analysis and critical control point (HACCP) and good practice in food industry, to assess their knowledge of and compliance with food safety practices. A checklist of 27 items was used to evaluate facility and meat handler hygiene and butcher shop maintenance. Our results revealed some lack of compliance in all the areas evaluated. The mean knowledge and practice score among the operators was 68.0%, and the mean "visual inspection" score for the butcher shops was 64.0%. Severe deficiencies were observed in the mandatory implementation of HACCP principles in this type of small food business. These findings indicate a need to modify training to enhance compliance with European food safety regulations at this step of the meat chain.

To verify age and education effects on communication performance of healthy adults in the Montreal Communication Evaluation Battery, Portuguese version (MAC-PT). The sample comprised 90 healthy adults from Portugal, European Portuguese speakers, divided into nine groups according to educational level (4-9, 10-13, and > 13 years of formal schooling) and age (19-40, 41-64, and 65-80 years). The influence of age and education was assessed by comparing mean scores between groups, using a two-way analysis of variance followed by Bonferroni post hoc tests (p ≤ 0.05). The results showed that participants' performance was influenced by age in pragmatic-inferential, discursive, and prosodic tasks. Education had the greatest influence on the performance in all processes evaluated by the MAC-PT. Age and education seem to influence the communicative performance and should be considered in the assessment of neurological patients.

There are several methodologies to assess the risk involved in Manual Materials Handling (MMH). The aim of this study was to identify the knowledge and use of risk assessment methods among Portuguese Health and Safety (H&S) practitioners. The study involved the participation of 331 H&S practitioners and other related prevention professionals. An e-mail invitation to complete an online survey was sent to all Portuguese registered H&S practitioners. The previously developed and validated questionnaire included three different sections: (1) company characteristics; (2) description of types of MMH tasks performed; and (3) the respondents' use of and knowledge about risk assessment methods for MMH tasks. The answers obtained were collected from almost 350 companies. The characteristics of the companies showed that there is a predominance of external and internal H&S services for Small and Medium sized Enterprises (SMEs) and large companies, respectively. The NIOSH equation, Key Indicator Method (KIM) and Manual Assessment Chart (MAC) were identified as the most used and recognised risk assessment methods. Questionnaire results show that an important number of Portuguese H&S practitioners recognise some methods but have difficulty applying them correctly. Some practitioners reported that they had never used any type of risk assessment method.

Measures to control tuberculous infection are crucial to prevent nosocomial transmission and protect health care workers (HCWs). In Portugal, the extent of implementation of tuberculosis (TB) control measures in hospitals is not known. To determine the current implementation of preventive measures for tuberculous infection at administrative, environmental and personal levels in Portuguese hospitals. A cross-sectional evaluation was performed using two anonymous questionnaires: one sent to all the hospital infection control (IC) committees and the other sent to all pulmonologists and physicians specialising in infectious disease. Fourteen IC committees and 72 physicians responded. According to the IC committees, 92% of hospitals had a written TB control plan, but only 37% of the physicians said there was always/almost always a fast track for diagnosing suspected pulmonary TB cases. The majority of the hospitals had an isolation policy (85%) and these patients were always/almost always admitted in separate rooms, according to 70% of physicians. Both HCWs and TB patients used respiratory protection equipment (92%). These findings indicate that the most basic TB IC measures had been undertaken, but some TB IC measures were not fully implemented at all hospitals. An institutional effort should be made to solve this problem and strengthen TB prevention activities.

In this short contribution, geomagnetic measurements in Central Africa made by Capelo and Ivens - two Portuguese explorers - during the years 1877 and 1885 are provided. We show the scarce number of geomagnetic observation in Africa compiled until now. These Portuguese explorers performed a considerable amount of measurements of geomagnetic declination (44 measurements), inclination (50) and horizontal component (50) of the geomagnetic field. We compared the results attained by these keen observers with those derived from the global geomagnetic model by Jackson et al. [Jackson, A., Jonkers, A.,Walker, M., 2000. Four centuries of geomagnetic secular variation from historical records. Philos. Trans. R. Soc. Lond. 358, 957-990].

OBJECTIVES: to adapt and validate the Inventory of Family Protective Factors (IFPF) for the Portuguese culture. This instrument assesses protective factors that contribute to family resilience. Studies addressing resilience are embedded within the salutogenic paradigm, i.e. it addresses protective factors of individuals or groups without underestimating risk factors or vulnerability. METHOD: in order to assess the IFPF's linguistic and conceptual equivalence, the instrument was translated, retro-translated and the think-aloud protocol was used. We then verified the instrument's sensitiveness, reliability and validity of results to assess its psychometric characteristics. A factor analysis was performed of the principal components with varimax rotation of the scale's items and Cronbach's alpha coefficient was calculated for each dimension. A total of 85 families with disabled children, selected through simple random sampling, self-administered the instrument. RESULTS: the IFPF presents psychometric characteristics that are appropriate for the Portuguese population (Cronbach's alpha = .90). CONCLUSION: the IFPF was adapted and validated for the Portuguese culture and is an instrument to be used in studies intended to assess protective factors of family resilience. PMID:25591096

This study analyzes the psychometric properties of the Portuguese version of the Quality of Life Questionnaire (QOL-Q; Quality of Life Questionnaire Manual - 1993 Manual and 2004 Revision. 2004, IDS Publishing Company, Worthington, OH; Schalock & Keith 2004). The analysis of the factorial structure was carried out on a sample of 304 adults with intellectual disabilities, through the use of confirmatory (CFA) and exploratory (EFA) factor analysis. The relationships of the QOL-Q with life satisfaction and self-concept measures were determined in groups composed of respectively 72 and 78 adults with intellectual disabilities. Confirmatory factorial analysis indicated a poor adjustment of the original factor structure to the Portuguese data. EFA indicated the existence of four factors, which include 30 items, and that were also supported by CFA. The total score of the QOL-Q revealed a reduced correlation with life satisfaction, and a moderate correlation with the self-concept. The Portuguese version of the QOL-Q shows satisfactory psychometric properties, but also some limitations. © 2012 Blackwell Publishing Ltd.

Relative Importance Assigned to Health Care Rationing Principles at the Bedside: Evidence From a Portuguese and Bulgarian Survey.

PubMed

Pinho, Micaela Moreira; Pinto Borges, Ana

Activity was undertaken to develop a Prioritization Scoring Index for Portugal and Bulgaria that weights the importance given to ethical rationing principles that should guide decisions at the bedside. Data from two random samples of 355 Portuguese and 298 Bulgarian members of the public were collected from an online questionnaire. Questions asked about the level of importance given to specific issues related to patient's prioritization criteria. Responses were analyzed quantitatively with the SPSS. In the process of selecting the patient to treat, Portuguese and Bulgarian respondents seem unanimous in giving greater importance to (i) the treatment outcomes, (ii) the severity of illness, (iii) children, and (iv) patients' fragility. In general, Portuguese and Bulgarian respondents allocate more than 50% of the prioritization weight to equity considerations, approximately 35% to efficiency considerations, and 5% to lottery selection. Even so, Bulgarian respondents rate highly the equity and less the efficiency consideration than Portuguese respondents. Although the pursuit of efficiency seems to be valued by respondents, their major concern seems to be with the reduction of inequalities in health.

Word-initial rhotic clusters in typically developing children: European Portuguese.

PubMed

Ramalho, Ana Margarida; Freitas, M João

2018-01-01

Rhotic clusters are complex structures segmentally and prosodically and are frequently one of the last structures acquired by Portuguese-speaking children. This paper describes cross-sectional data for word-initial (WI) rhotic tap clusters in typically developing 3-4- and 5-year-olds in Portugal. Additional information is provided on WI /l/ as a singleton and in clusters. A native speaker audio-recorded and transcribed single words in a story-telling task. Results for WI rhotic clusters show an age effect consistent with previous research on European Portuguese. Singleton /l/ was in advance of /l/-clusters as expected, but the tap clusters were in advance of the /l/-clusters, possibly reflecting the velarized characteristics of the lateral. The prosodic variables word stress and word length were relevant for the WI rhotic clusters: shorter words and stressed syllables showed higher accuracy. Finally, mismatches ('errors') mainly reflected negative structural constraints (deletion of C2 and epenthesis) rather than segmental constraints (substitutions).

ABSTRACT OBJECTIVE To assess the construct validity and reliability of the Portuguese version of the European Task Force on Patient Evaluation of General Practice Care questionnaire. METHODS We applied the Portuguese version of the European Task Force on Patient Evaluation of General Practice Care to 392 users of 20 Family Health Units from the North of Portugal. The validity of the construct was evaluated by exploratory factor analysis, with the Principal Axis Factoring method, by orthogonal rotation (varimax procedure), by the Kaiser normalization criteria (eigenvalue ≥ 1). The factorability of the data matrix was verified by the Kaiser-Meyer-Olkin and Bartlett’s sphericity test. We estimated the reliability by the indicator of internal consistency Cronbach’s alpha. To analyze the correlations between satisfaction and loyalty, we used the Pearson correlations. The predictor effect of satisfaction on loyalty was analyzed by simple linear regression. RESULTS Satisfaction presented five robust and well individualized dimensions – medical care, nursing care, clinical secretariat services, accessibility, and organization of services – with alpha values between 0.86 and 0.97, good levels of internal consistency. The loyalty showed alpha value of 0.72, considered a reasonable internal consistency. The satisfaction was predictive of loyalty. CONCLUSIONS The Portuguese European Task Force on Patient Evaluation of General Practice Care questionnaire is a robust and reliable instrument to measure the satisfaction and loyalty of users of the Family Health Units.

In Portugal, the frequency of patient with treated and controlled hypertension is low. It is unknown the relation of socio-economic determinants with hypertension control, particularly in African immigrants. To compare frequency of control in treated hypertension and to identify characteristics associated with uncontrolled and treated hypertension between Portuguese natives (Caucasian) and Portuguese Speaking African Coutries immigrants (black). Cross-sectional study of patients with treated hypertension, 40-80 years old, randomized from Primary Health Care of Lisbon Region. We collected sociodemographic, clinical and health care data through structured interviews. We compared the frequency of patients with uncontrolled hypertension, and identified related factors through univariate and multivariate analysis. In this study participated 786 patients with treated hypertension (participation rate: 71%): 449 natives and 337 immigrants. Of these, 46% had controlled hypertension. Diastolic blood pressure was higher in younger immigrants. Were associated with no control, in natives, male sex, low education, going to emergency and / or nursing services and not looking for the family doctor; on immigrants, being single, using the pharmacist, the number of years of illness and intentional non-adherence. Treated hypertension control has been increasing for last years. Natives and immigrants differ, regarding blood pressure control, relatively to the frequency of family doctor consultation, and resorting to other services and health professionals. These differences didn't reflect in statistically different control rates. It is needed to define strategies to control hypertension in primary health care specific for ethnic groups.

Portugal is impacted by the rapid growth of the aging population, which has significant implications for its health care system. However, nurses have received little education focusing on the unique and complex care needs of older adults. This gap in the nurses' education has an enormous impact in their knowledge and attitudes and affects the quality of nursing care provided to older adults. A cross-sectional study was conducted among 1068 Portuguese nurses in five hospitals (northern and central region) with the following purposes: (i) explore the knowledge and attitudes of nurses about four common geriatric syndromes (pressure ulcer, incontinence, restraint use and sleep disturbance) in Portuguese hospitals; and (ii) evaluate the influence of demographic, professional and nurses' perception about hospital educational support, geriatric knowledge, and burden of caring for older adults upon geriatric nursing knowledge and attitudes. The mean knowledge and attitudes scores were 0.41 ± 0.15 and 0.40 ± 0.21, respectively (the maximum score was 1). Knowledge of nurses in Portuguese hospitals about the four geriatric syndromes (pressure ulcers, sleep disturbance, urinary incontinence and restraint use) was found inadequate. The nurses' attitudes towards caring for hospitalized older adults were generally negative. Nurses who work in academic hospitals demonstrated significantly more knowledge than nurses in hospital centers. The attitudes of nurses were significantly associated with the hospital and unit type, region, hospital educational support, staff knowledge, and perceived burden of caring for older adults. The study findings support the need for improving nurses' knowledge and attitudes towards hospitalized older adults and implementing evidence-based guidelines in their practice. © 2014 Nordic College of Caring Science.

Cross-cultural adaptation and analysis of measurement properties. To translate and cross-culturally adapt the Lumbar Spine Instability Questionnaire (LSIQ) into Brazilian-Portuguese and to test its measurement properties in Brazilian patients with low back pain. The selection of subgroup of patients that respond better to specific interventions is the top research priority in the field of back pain. The LSIQ is a tool able to stratify patients with low back pain who responds better to motor control exercises. There is no Brazilian-Portuguese version of the LSIQ available. The original version of the LSIQ was translated and cross-culturally adapted. We collected data from 100 patients with low back pain. In addition to LSIQ, we also collected information about physical activity levels (measured by the International Physical Activity Questionnaire short version), disability (measured by the Roland Morris Disability Questionnaire), pain intensity (measured by the Pain numerical Rating Scale), kinesiophobia (measured by the Tampa Scale of Kinesiophobia), and depression (measured by the Beck Depression Inventory). The measurement properties tested were internal consistency, reproducibility (reliability and agreement), construct validity, and ceiling and floor effects. The Brazilian-Portuguese version of the LSIQ showed good measurement properties with a Cronbach alpha of 0.79, an intraclass correlation coefficient of 0.75, a standard error of measurement of 1.65 points, and a minimal detectable change of 3.54 points. We did not detect ceiling and floor effects. The construct validity analysis was observed a moderate correlation between the LSIQ and Pain Numerical Rating Scale r = 0.46, Roland Morris Disability Questionnaire r = 0.66, Tampa Scale of Kinesiophobia r = 0.49, and Beck Depression Inventory r = 0.44. The Brazilian-Portuguese version of LIQ has adequate measurement properties and can be used in clinical practice and research. NA.

To evaluate the antimicrobial resistance traits of staphylococci responsible for subclinical bovine mastitis in Portugal, the minimum inhibitory concentrations (MIC) of 7 antimicrobial agents, frequently administered for mastitis treatment, were determined for 30 Staphylococcus aureus and 31 Staphylococcus epidermidis field isolates. Beta-lactamase production was detected through the use of nitrocefin-impregnated discs. The MIC that inhibited 90% of the isolates tested (MIC90) of penicillin, oxacillin, cefazolin, gentamicin, sulfamethoxazole/trimethoprim, oxytetracycline, and enrofloxacin were, respectively, 4, 0.5, 1, 1, 0.25, 0.25, and 0.06 microg/mL for Staph. aureus and > or = 64, 8, 1, 32, > or = 64, > or = 64, and 0.06 microg/mL for Staph. epidermidis. All Staph. aureus isolates showed susceptibility to oxacillin, cefazolin, gentamicin, sulphamethoxazole/trimethoprim, and enrofloxacin. Beta-lactamase production was detected in 20 of these isolates (66.7%), all of which were resistant to penicillin. Of the 31 Staph. epidermidis tested, 24 (77.4%) were beta-lactamase positive. All isolates were susceptible to both cefazolin and enrofloxacin. Nine Staph. epidermidis isolates were resistant to oxacillin, with MIC values ranging from 4 to 8 microg/mL. The MIC values of 5 antimicrobial agents tested were higher than those reported in other countries. Enrofloxacin was the only exception, showing lower MIC values compared with other reports. Overall, the antimicrobial agents tested in our study, with the exception of penicillin, were active against the 61 isolates studied.

To translate the Quebec Sleep Questionnaire (QSQ), a specific instrument for the assessment of quality of life in patients with sleep obstructive apnea, into Portuguese and to create a version that is cross-culturally adapted for use in Brazil. The Portuguese-language version was developed according to a rigorous methodology, which included the following steps: preparation; translation from English into Portuguese in three versions; reconciliation to a single version; back-translation of that version into English; comparison and harmonization of the back-translation with the original version; review of the Portuguese-language version; cognitive debriefing; text review; and arrival at the final version. The Portuguese-language version of the QSQ for use in Brazil had a clarity score, as measured by cognitive debriefing, ranging from 0.81 to 0.99, demonstrating the consistency of translation and cross-cultural adaptation processes. The process of translating the QSQ into Portuguese and creating a version that is cross-culturally adapted for use in Brazil produced a valid instrument to assess the quality of life in patients with obstructive sleep apnea.

Social phobia (also known as social anxiety disorder) is a severe mental disorder that brings distress and disability. The aim of this study was validate to the Portuguese language the Mini-Social Phobia Inventory (Mini-SPIN) in a populational sample. We performed a discriminative validity study of the Mini-SPIN in a sample of 644 subjects (Mini-SPIN positive group: n = 218 and control/negative group: n = 426) of a study of anxiety disorders' prevalence in the city of Santo André-SP. The Portuguese version of the Mini-SPIN (with score of 6 points, suggested in the original English version) demonstrated a sensitivity of 95.0%, specificity of 80.3%, positive predictive value of 52.8%, negative predictive value of 98.6% and incorrect classification rate of 16.9%. With score of 7 points, was observed an increase in the specificity and positive predictive value (88.6% and 62.7%), while the sensitivity and negative predictive value (84.8% and 96.2%) remained high. The Portuguese version of the Mini-SPIN showed satisfactory psychometric qualities in terms of discriminative validity. In this study, the cut-off of 7, was considered to be the most suitable to screening of the generalized social phobia.

Worries are common in surgical patients, especially in children. The present study analyzed the factor structure and the psychometric properties of a Portuguese version of the Child Surgery Worries Questionnaire (CSWQ-P) in a Portuguese sample of 490 children. Exploratory factor analysis, conducted via principal axis factoring with oblimin rotation, provided evidence for a four-factor structure of the 21 item questionnaire. A confirmatory factor analysis was also conducted, showing the good fit of this solution. The CSWQ-P proved to have one more subscale than the original Spanish version CSWQ. Correlations with the children's trait anxiety provided evidence of convergent validity for the CSWQ-P. Females also scored higher on worries than males on all subscales. Psychometric properties of this revised version of the CSWQ provided support for use with young children, and indicate the CSWQ-P has value for use in healthcare practice and in clinical research.

Unbiased cluster analysis using clinical parameters has identified asthma phenotypes. Adding inflammatory biomarkers to this analysis provided a better insight into the disease mechanisms. This approach has not yet been applied to asthmatic Portuguese patients. To identify phenotypes of asthma using cluster analysis in a Portuguese asthmatic population treated in secondary medical care. Consecutive patients with asthma were recruited from the outpatient clinic. Patients were optimally treated according to GINA guidelines and enrolled in the study. Procedures were performed according to a standard evaluation of asthma. Phenotypes were identified by cluster analysis using Ward's clustering method. Of the 72 patients enrolled, 57 had full data and were included for cluster analysis. Distribution was set in 5 clusters described as follows: cluster (C) 1, early onset mild allergic asthma; C2, moderate allergic asthma, with long evolution, female prevalence and mixed inflammation; C3, allergic brittle asthma in young females with early disease onset and no evidence of inflammation; C4, severe asthma in obese females with late disease onset, highly symptomatic despite low Th2 inflammation; C5, severe asthma with chronic airflow obstruction, late disease onset and eosinophilic inflammation. In our study population, the identified clusters were mainly coincident with other larger-scale cluster analysis. Variables such as age at disease onset, obesity, lung function, FeNO (Th2 biomarker) and disease severity were important for cluster distinction. Copyright © 2015.

The scope of this study is to conduct an assessment of the media coverage and dissemination of health issues in Portugal in order to problematize the aspects of coverage and invisibility of health topics and establish the themes neglected in media coverage. To achieve this, the coverage on health issues in the Portuguese daily newspaper Público was compared with the epidemiological context regarding health priorities and the perceptions of key players on media dissemination and the themes that are relevant to the Portuguese population. The results showed that the recurrent health-associated themes do not deal with diseases per se, but with the politics and economics of health and medication. The themes neglected in media coverage identified in the Portuguese context include: communicable diseases, such as hepatitis and tuberculosis; issues related to mental health and suicide; and ailments and social consequences associated with the economic crisis that has beset Portugal recently. From the standpoint of the people interviewed, other neglected diseases include hemochromatosis and other rare diseases. In tandem with this, the study highlights the well covered media themes that revolve around the lives and activities of celebrities, which are exhaustively aired in the communication media in the country.

After following all steps of the translation process, for the validation process, the event III Workshop Brazil - Portugal: Care Delivery to Critical Patients was created, promoted by one Brazilian and another Portuguese teaching institution. 103 nurses participated. As to the validity and reliability of the scale, the correlation pattern between the variables, the sampling adequacy test (Kaiser-Meyer-Olkin) and the sphericity test (Bartlett) showed good results. In the exploratory factorial analysis (Varimax), item 9 behaved better in factor 1 (Satisfaction) than in factor 2 (Self-confidence in learning). The internal consistency (Cronbach's alpha) showed coefficients of 0.86 in factor 1 with six items and 0.77 for factor 2 with 07 items. In Portuguese this tool was called: Escala de Satisfação de Estudantes e Autoconfiança na Aprendizagem. The results found good psychometric properties and a good potential use. The sampling size and specificity are limitations of this study, but future studies will contribute to consolidate the validity of the scale and strengthen its potential use.

The internet has proven to be a valuable resource for self-care, allowing access to information and promoting interaction between professionals, caregivers, users of health care services and people interested in health information. However, recurring searches are often related to excessive health anxiety and a phenomenon known as cyberchondria can have impacts on physical and mental health. Within this background, a Cyberchondria Severity Scale has been developed to differentiate healthy and unhealthy behavior in internet searches for health information, based on the following criteria: compulsion, distress, excesses, and trust and distrust of health professionals. To conduct cross-cultural adaptation of the Cyberchondria Severity Scale for Brazilian Portuguese, because of the lack of an appropriate instrument for Brazil. This study was authorized by the original author of the scale. The process was divided into the following four steps: 1) initial translation, 2) back-translation, 3) development of a synthesized version, and 4) experimental application. Translation into Brazilian Portuguese required some idiomatic expressions to be adapted. In some cases, words were not literally translated from English into Portuguese. Only items 7, 8, 12, 23 and 27 were altered, as a means of both conforming to proper grammar conventions and achieving easy comprehension. The items were rewritten without loss of the original content. This paper presents a translated version of the Cyberchondria Severity Scale that has been semantically adapted for the Brazilian population, providing a basis for future studies in this area, which should in turn contribute to improved understanding of the cyberchondria phenomenon in this population.

To translate, culturally adapt and psychometrically validate the Information Needs in Cardiac Rehabilitation (INCR) tool to Portuguese. The identification of information needs is considered the first step to improve knowledge that ultimately could improve health outcomes. The Portuguese version generated was tested in 300 cardiac rehabilitation patients (CR) (34% women; mean age = 61.3 ± 2.1 years old). Test-retest reliability was assessed using intraclass correlation coefficient (ICC), the internal consistency using Cronbach's alpha, and the criterion validity was assessed with regard to patients' education and duration in CR. All 9 subscales were considered internally consistent (á > 0.7). Significant differences between mean total needs and educational level (p < 0.05) and duration in CR (p = 0.03) supported criterion validity. The overall mean (4.6 ± 0.4), as well as the means of the 9 subscales were high (emergency/safety was the greatest need). The Portuguese INCR was demonstrated to have sufficient reliability, consistency and validity. Copyright © 2014 Elsevier Inc. All rights reserved.

The aim of this study was to analyse differences in quality of life (QOL) between Spanish and Portuguese immigrant and native adolescents. In total, 475 native and immigrant adolescents (52% boys) from Algarve (Portugal) and Huelva (Spain), aged between 12 and 17 years old, were assessed with the KIDSCREEN-52. QOL dimensions were not related to most academic variables, with the exception of number of school failures, Financial Resources and Social Support from Peers. Multivariate analysis of variance (MANOVA) was used to examine statistical differences in adolescents QOL. Age differences in QOL levels were not found. Girls reported worse QOL levels on Physical Wellbeing than boys (F = 10.32, p = .001, η2 =.02). Immigrant Portuguese adolescents scored higher on Mood (F = 17.57, p = .000, η2 =.11), and native Portuguese adolescents scored higher on Social Acceptance (F = 4.87, p = .002, η2=.033). Immigrant and native adolescents had similar levels of perceived QOL. Overall, it seems that in both countries, the living contexts for immigrant and native adolescents are fairly homogeneous.

Advertisements from "Lonely Hearts" columns in the major daily Portuguese newspaper (Jornal de Notícias) were used to test hypotheses about the mate preferences of men and women. A total of 484 advertisements were coded for demographic descriptors and offers of and appeals for attractiveness, financial security, sincerity, expressiveness, and instrumentality, e.g., intelligence and ambition. Some results supported social exchange and evolutionary predictions: men sought younger women and offered security; women sought older men with status and resources. However, other results challenged such predictions: attractiveness and expressiveness did not differ by sex.

Worldwide we are facing a serious demographic challenge due to the dramatic growth of the population over 60 years. It is expected that the proportion of this population will nearly double from 12 to 22 %, between 2015 and 2050. This demographic shift comes with major health and socio-economic concerns. Nutrition is a fundamental determinant of both health and disease and its role in extending a healthy lifespan is the object of considerable research. Notably, malnutrition is one of the main threats to health and quality of life among the elderly. Therefore, knowledge about nutritional status among the elderly is essential for the promotion and maintenance of healthy ageing and to support the development of health protection policies and equity in elderly health care. This is a nationwide nutrition survey of the Portuguese population over 65 years old, with data collection through face-to-face interviews. A representative and random sample of community dwelling elderly and nursing homes residents will be obtained by multistage sampling stratified per main Portuguese regions, sex and age groups. Minimum sample size was estimated to be 2077 elderly (979 in the community and 1098 in nursing homes). Data will be collected on food habits and eating patterns, nutritional status, food insecurity, lifestyle, self-rated general health status and self-reported diseases, functionality, loneliness, cognitive function, emotional status and demographic and socio-economic characterization. This is the first national survey to evaluate the prevalence of nutritional risk and malnutrition of the Portuguese population above 65 years old, including those living in nursing homes. It will allow the identification of population subgroups of elderly with increased odds of malnutrition and nutritional risk. In addition, this survey will contribute to the identification of psychosocial and clinical predictors of malnutrition among elderly, which is an important risk factor for other

An operational system for the forecast of oceanographic conditions off the Portuguese coast is presently being implemented at Instituto Hidrográfico (IH), in the framework of project MOCASSIM. The system is planned to use a broad range of observations provided both from IH observational networks (wave buoys, tidal gauges) and programs (hydrographic surveys, moorings) as well as from external sources. The MOCASSIM system integrates several numerical models which, combined, are intended to cover the relevant physical processes observed in the geographical areas of interest. At the present stage of development the system integrates a circulation module and a wave module. The circulation module is based on the Harvard Ocean Prediction System (HOPS), a primitive equation model formulated under the rigid lid assumption, which includes a data assimilation module. The wave module is based on the WaveWatch3 (WW3) model, which provides wave conditions in the North Atlantic basin, and on the SWAN model which is used to improve the wave forecasts on coastal or other specific areas of interest. The models use the meteorological forcing fields of a limited area model (ALADIN model) covering the Portuguese area, which are being provided in the framework of a close colaboration with Instituto de Meteorologia. Although still under devellopment, the MOCASSIM system has already been used in several operationnal contexts. These included the operational environmental assessment during both national and NATO navy exercises and, more recently, the monitoring of the oceanographic conditions in the NW Iberian area affected by the oil spill of MV "Prestige". The system is also a key component of ongoing research on the oceanography of the Portuguese continental margin, which is presently being conducted at IH in the framework of national and European funded projects.

In this work we build the first BI-RADS parser for Portuguese free texts, modeled after existing approaches to extract BI-RADS features from English medical records. Our concept finder uses a semantic grammar based on the BIRADS lexicon and on iterative transferred expert knowledge. We compare the performance of our algorithm to manual annotation by a specialist in mammography. Our results show that our parser’s performance is comparable to the manual method. PMID:23797461

Depression is a serious psychological problem in the palliative care setting. Brief screening tools for depression are lacking and need to be brief and acceptable. This study aimed to identify the properties of the single Portuguese question "Está deprimido?" ("Are you depressed?") to screen for depression. Retrospective study from 100 patient's medical records identifying the answers on the single Portuguese question for depression "Está deprimido?" ("Are you depressed?") and the HADS depression sub-scale, using a score ≥11 on the latter as the gold standard for clinically significant depressive symptoms. Sensitivity, specificity, positive predictive and negative values were calculated. Response rate for the single Portuguese question for depression was 100%. Prevalence of depression symptoms (HADS-d ≥ 11) was 43%. To the question "Está deprimido?" 60 patients responded "yes." Sixteen patients who replied "no" to the single question had clinically significant depressive symptoms based on the HADS depression sub-scale. The single tool had 65.2% sensitivity, 49.2% specificity and 50.0% and 64.4% of positive predictive and negative values, respectively. In this first preliminary retrospective Portuguese study, the single question for depression has shown poor screening properties. Future research in larger and mixed patientś samples of Portuguese terminally ill is necessary to find more accurate and robust properties of this brief tool.

Imaginaries of nuclear energy in the Portuguese parliament: Between promise, risk, and democracy.

Santos Pereira, Tiago; Carvalho, António; Fonseca, Paulo F C

2017-04-01

This article explores the evolution of the nuclear energy debate and its associated controversies in the Portuguese parliament. The analysis focuses on the dictatorial regime of the New State (from the beginning of the nuclear program in 1951 until the 1974 revolution) and on the democratic period (post-1974). Portugal, as an exporting country of uranium minerals, significantly invested in the development of a national capacity in nuclear research, but never developed an endogenous nuclear power infrastructure. Through the analysis of parliamentary debates, this article characterizes the dynamic evolution of the Portuguese sociotechnical imaginary on nuclear energy and technology interlinked with ambivalent representations, including the promise of nuclear energy as key for the constitution of a technological Nation or as prompting new sociotechnical risks.

[An analysis of code-switching phenomenon in bimodal bilinguals (Libras and Portuguese).

An interesting linguistic phenomenon that happens in the interaction among bilingual people is code-switching. In this paper, we are investigating code-switching among oral Brazilian Portuguese and Brazilian Sign Language - Libras, in a same enunciative chain, with the goal of identifying and analyzing the use of code-switching in the speech of a child and an adult (both hearing from deaf parents), interacting in an intermodal bilingual context, with deaf and hearing interlocutors. Code-switching in languages, in this case, occurs when a person stops to speak in Portuguese and he/she alternates to sign. This present research is a starting study, with qualitative analysis of data. Our corpus is composed of nine sections of interactions in Libras and oral Portuguese, recorded in video, part of the Bimodal Bilingual Development Project from UFSC. The data shows that adult and child's characteristics of code-switching seem to have similarities and differences. The adult seems to switch more worried about the course of the interaction. On the other hand, the child did not seem to use code-switching for specific pragmatic reasons. In regard to the switching extension, it is noted that both the child and the adult used more than one word sentences. The role of the interlocutors seems to be decisive in the interactions investigated here - especially for the adult, since the child is still acquiring awareness about the role of the interlocutor in an interaction.

The objectives of this study were to develop a unified Portuguese-language version, for use in Brazil and Portugal, of the Body Shape Questionnaire (BSQ) and to estimate its validity, reliability, and internal consistency in Brazilian and Portuguese female university students. Confirmatory factor analysis was performed using both original (34-item) and shortened (8-item) versions. The model's fit was assessed with χ²/df, CFI, NFI, and RMSEA. Concurrent and convergent validity were assessed. Reliability was estimated through internal consistency and composite reliability (α). Transnational invariance of the BSQ was tested using multi-group analysis. The original 32-item model was refined to present a better fit and adequate validity and reliability. The shortened model was stable in both independent samples and in transnational samples (Brazil and Portugal). The use of this unified version is recommended for the assessment of body shape concerns in both Brazilian and Portuguese college students.

ABSTRACT Objective: To translate the Quebec Sleep Questionnaire (QSQ), a specific instrument for the assessment of quality of life in patients with sleep obstructive apnea, into Portuguese and to create a version that is cross-culturally adapted for use in Brazil. Methods: The Portuguese-language version was developed according to a rigorous methodology, which included the following steps: preparation; translation from English into Portuguese in three versions; reconciliation to a single version; back-translation of that version into English; comparison and harmonization of the back-translation with the original version; review of the Portuguese-language version; cognitive debriefing; text review; and arrival at the final version. Results: The Portuguese-language version of the QSQ for use in Brazil had a clarity score, as measured by cognitive debriefing, ranging from 0.81 to 0.99, demonstrating the consistency of translation and cross-cultural adaptation processes. Conclusions: The process of translating the QSQ into Portuguese and creating a version that is cross-culturally adapted for use in Brazil produced a valid instrument to assess the quality of life in patients with obstructive sleep apnea.

Early sound patterns in the speech of two Brazilian Portuguese speakers.

PubMed

Teixeira, Elizabeth Reis; Davis, Barbara L

2002-06-01

Sound patterns in the speech of two Brazilian-Portuguese speaking children are compared with early production patterns in English-learning children as well as English and Brazilian-Portuguese (BP) characteristics. The relationship between production system effects and ambient language influences in the acquisition of early sound patterns is of primary interest, as English and BP are characterized by differing phonological systems. Results emphasize the primacy of production system effects in early acquisition, although even the earliest word forms show evidence of perceptual effects from the ambient language in both BP children. Use of labials and coronals and low and midfront vowels in simple syllable shapes is consistent with acquisition data for this period across languages. However, potential ambient language influences include higher frequencies of dorsals, use of multisyllabic words, and different phone types in syllable-offset position. These results suggest that to fully understand early acquisition of sound systems one must account for both production system effects and perceptual effects from the ambient language.

As the world population ages, mental health professionals increasingly need empirically supported assessment instruments for older adult psychopathology. This study tested the degree to which syndromes derived from self-ratings of psychopathology by elders in the US would fit self-ratings by elders in Portugal. The Older Adult Self-Report (OASR) was completed by 352 60- to 102-year-olds in Portuguese community and residential settings. Confirmatory factor analyses tested the fit of the 7-syndrome OASR model to self-ratings by Portuguese elders. The primary fit index (Root Mean Square Error of Approximation) showed good fit, while secondary fit indices (the Comparative Fit Index and the Tucker-Lewis Index) showed acceptable fit. Loadings of 95 of the 97 items on their expected syndromes were statistically significant (mean = .63), indicating that the items measured the syndromes well. Correlations between latent factors, ie, between the hypothesized syndrome constructs measured by the items, averaged .66. The correlations between syndromes reflect varying degrees of comorbidity between problems comprising particular pairs of syndromes. The results support the syndrome structure of the OASR for Portuguese elders, offering Portuguese clinicians and researchers a useful instrument for assessing a broad spectrum of psychopathology. The results also offer a core of empirically supported taxonomic constructs of later life psychopathology as a basis for advancing clinical practice, training, and cross-cultural research.

Recent research has examined young women's sexual subjectivities and desires, yet has neglected the ways women in their twenties account for their sexual selves. The present study focuses on the discourses and discursive constructions available for young Portuguese women when talking about their sexual subjectivity. Data were collected through six focus group discussions with young Portuguese women. The goal was to analyse discursive constructions and their potential implications for sexual empowerment and resistance. In the course of the work, it was possible to identify several different discursive devices, the most pervasive of which were Pandora's Box, Protocol and Process. Each of these constructions tended to be negative or contain negative judgements about women's sexuality. Even in contexts where a positive discourse on women's sexual desires emerged, significant constraints were encountered in achieving of a fulfilling and positive sexual experience.

Portuguese Familial Hypercholesterolemia Study: presentation of the study and preliminary results.

PubMed

Bourbon, Mafalda; Rato, Quitéria

2006-11-01

Familial hypercholesterolemia (FH) is an autosomal dominant genetic disorder caused, in the majority of cases, by a partial or total lack of functional low density lipoprotein receptors (LDLR). Mutations in the LDLR gene lead to increased plasma cholesterol levels, resulting in cholesterol deposition in the arteries, thereby increasing the risk of premature coronary heart disease. The homozygous form of FH is rare but heterozygous FH is common, although underdiagnosed in many populations, including the Portuguese. In 1999 the Portuguese Familial Hypercholesterolemia Study was begun at the National Institute of Health. The aim of the Portuguese Familial H ypercholesterolemia Study is to perform an epidemiological study to determine the prevalence and distribution of FH in Portugal and to better understand the pathophysiology of coronary heart disease in these patients. The aim of the present work is to present the study's criteria and organization as well as its preliminary results. The study population consists of individuals of both sexes and all ages with a clinical diagnosis of FH, with biochemical and molecular characterization being performed. The clinical criteria used for the diagnosis of FH were adapted from those of the Simon Broome Heart Research Trust. The study is organized in five stages: 1. selection of individuals with a clinical diagnosis of FH; 2. completion of a clinical questionnaire and declaration of informed consent; 3. collection of blood samples; 4. biochemical characterization; 5. molecular study of three genes associated with the FH phenotype: LDLR, apolipoprotein B (APOB) and proprotein convertase subtilisin/kexin type 9 (PCSK9). Between 1999 and June 2006 the LDLR gene and the APOB gene of 141 index cases (38 children and 103 adults) were studied. In 78 of these index cases (76 heterozygotes and two homozygotes) 50 different mutations in the LDLR gene were identified, and two unrelated individuals were found to have the ApoB3500 mutation

Alternative and complementary therapy systems, such as homeopathy, have long been used around the world. Since 1995 homeopathy has been officially recognized in Europe as a system of medicine or a medical specialty. Portuguese community pharmacists have long-standing experience with homeopathic products. By contrast, healthcare professionals in Turkey are less experienced with homeopathic practice although there is a new regulatory setting in place. There are a limited number of studies addressing pharmacists' role within the homeopathic system. To investigate the attitudes (knowledge, feelings and behaviour) of experienced Portuguese pharmacy practitioners who deal with homeopathy, and thus to inform Turkish pharmacy practice and policy on homeopathy-related success factors. A qualitative cross-sectional design was followed, using semi-structured and face-to-face individual interviews with purposively selected Portuguese pharmacists experienced with homeopathic medicines. Audio-recordings were transcribed verbatim and the transcriptions imported into QSR NVivo v10 software for qualitative coding and analysis. Using a thematic content approach, the extracted codes were grouped and indexed by recurrent themes through a reflective procedure and constant comparison. Six general themes emerged, the most relevant being participants' feelings of gratitude for the ability to work in homeopathy; other themes were a helpful regulatory body, clear practice boundaries, scientific support and product quality assurance. Specialized homeopathic education was considered the most important factor for success. This was related to patients' positive perceptions and acceptance, suggesting an increase in public awareness through the pharmacy network. Portuguese pharmacists' attitudes towards their homeopathic practices highlighted the key elements for success in a field that is usually distant from traditional pharmaceutical education and practice. The present findings provide

Acute heart failure (AHF) is a heterogeneous clinical syndrome requiring urgent therapy. The prognosis is poor after the index hospitalization, with a high risk for rehospitalization and early death. The costs of managing AHF are thus increasing rapidly. A literature review was performed to gather and compare data on prevalence and treatment and to identify gaps in AHF management, based on European and Portuguese studies. A literature search from 1995 to 2014 was conducted in selected databases (BIOSIS Previews, EMBASE and Ovid MEDLINE). Seven Portuguese and nine European studies were analyzed. The mean age of AHF patients was ≥65 years and 30-50% were women. Coronary artery disease (42.3% vs. 61.9%) and hypertension (53.3% vs. 76.7%) were identified as primary etiologies in Europe and in Portugal. Similar proportions of heart failure with preserved ejection fraction were found in the Portuguese (19.9-44.7%) and European (32.8-39.1%) studies. Overall, all-cause mortality rates were comparable (six months: 9.3-25.5% vs. 13.5-27.4%; one year: 15.9-31% vs. 17.4-46.5%), as was in-hospital mortality (5.5-14% vs. 3.8-12%) in Portuguese and European studies, respectively. Length of stay was comparable. The studies were performed in very different hospital settings and data on treatment were scarce. Gaps were identified in treatment and clinical pathways of patients with AHF. Based on the results of this review, collection and investigation of data on the disease and treatment solutions, training in disease management, and improved organization of healthcare should be the subject of further investment.

Non-adherence to medical plans is recognized as an important problem in dialysis patients, since it has been associated with increased morbidity and mortality, resulting in disproportionately high costs of care. The success of renal replacement therapy depends on the adherence of patients to the different aspects of the therapeutic strategy, which includes a complex drug regimen involving a wide variety of drugs and doses, several prescribed dialysis sessions with different durations, dietetic recommendations and restriction of fluid intake. In this work, we aimed to translate and validate a previously described self-reported end-stage renal disease questionnaire (ESRD-AQ) to the Portuguese language (PESRD-AQ). After ESRD-AQ translation, a validation was performed by experts and by using a cohort of 185 Portuguese dialysis patients. PESRD-AQ reliability analysis showed strong test-retest stability across all items, with an intra-class correlation of 0.931. The average of the item-level content validity index by experts for the 46 items was 0.98, ranging from 0.94 to 1. Moreover, we found that PESRD-AQ scores indicative of non-adherence were associated with alterations in some biological and biochemical markers of non-adherence, including interdialytic weight gain. In conclusion, our results showed that PESRD-AQ, which presented an acceptable reliability and validity, is a valid tool to be used for adherence evaluation by Portuguese-speaking dialysis patients.

The purpose of this study was to analyze secular trends in anthropometrics and physical fitness of Portuguese children. A group of 1819 students (881 boys and 938 girls) between 10 and 11 years old was assessed in their 5th and 6th scholar grade throughout a 20 years' time-frame. ANCOVA models were used to analyze variations in anthropometrics (height, weight and body mass index) and physical fitness (sit and reach, curl-up, horizontal jump and sprint time) across four quinquennials (1993 - 1998; 1998 - 2003; 2003 - 2008; 2008 - 2013). Secular trends showed the presence of heavier boys and girls with higher body mass index in the 5th and 6th grade throughout the last 20 years. There was also a presence of taller girls but just until the 3rd quinquennial. Both boys and girls were able to perform better on the core strength test and sprint time but become less flexible over the years. Mean jumping performance remained unchanged for both genders. The present study provides novel data on anthropometrics and physical fitness trends over the last two decades in young Portuguese children, consistent with the results reported in other developed countries. Evidence for the start of a positive secular trend in body mass index and in some physical fitness components over the last two decades among the Portuguese youth.

The aim of this study was to examine any differences in cardiovascular disease (CVD) risk in Portuguese children split by parental educational level. A cross-sectional school-based study was conducted in 2011 on 359 Portuguese children (202 girls and 157 boys) aged 10 to 17 years (mean age ± SD = 13.9 ± 1.98 years). Height and body mass were assessed to determine body mass index (BMI). Parental education level (PEL) was used as a surrogate for socioeconomic status (SES). Capillary blood sampling was used to determine: Total Cholesterol (TC), Triglycerides (TG), Fasting Glucos (GLUC), High and Low Density Lipoprotein (HDL/LDL). These measurements were combined with measures of systolic blood pressure and cardiorespiratory fitness as z-scores. CVD risk was constructed by summing the z-scores. Analysis of covariance, controlling for BMI, indicated that CVD risk was significantly different across PEL groups (p = 0.01), with CVD risk score being significantly lower in low (p = 0.04) and middle (p = 0.008) PEL groups, compared to high PEL. Moreover, the covariate, BMI was also significant (p = 0.0001, β = 0.023), evidencing a significant positive association between BMI and CVD risk, with higher BMI associated with greater CVD risk. In Portuguese children, significantly greater CVD risk was found for children of high PEL, while higher BMI was associated with greater CVD risk. PMID:23330223

Purpose  To translate into Portuguese, culturally adapt and validate the Uterine Fibroid Symptom - Quality of Life (UFS-QoL) questionnaire for Brazilian women with uterine leiomyoma. Methods  Initially, the UFS-QoL questionnaire was translated into Brazilian Portuguese in accordance with international standards, with subsequent cultural, structural, conceptual and semantic adaptations, so that patients were able to properly answer the questionnaire. Fifty patients with uterine leiomyoma and 19 patients without the disease, confirmed by abdominal pelvic examination and/or transvaginal ultrasound, were selected at the outpatient clinics of the Department of Gynecology of the Universidade Federal de São Paulo (Unifesp). The UFS-QoL questionnaire was administered to all women twice on the same day, with two different interviewers, with an interval of 15 minutes between interviews. After 15 days, the questionnaire was re-administered by the first interviewer. Reliability (internal consistency and test-retest), construct and discriminative validity were tested to ratify the questionnaire. Results  The reliability of the instrument was assessed by Cronbach's α coefficient with an overall result of 0.97, indicating high reliability. The survey results showed a high correlation ( p  = 0.94; p  ≤ 0.001). Conclusion  The UFS-QoL questionnaire was successfully adapted to the Brazilian Portuguese language and Brazilian culture, showing reliability and validity.

OBJECTIVES: Oral health in Down syndrome children has some peculiar aspects that must be considered in the follow-up of these patients. This study focuses on characterizing the environmental and host factors associated with dental caries in Portuguese children with and without Down syndrome. METHODS: A sibling-matched, population-based, cross-sectional survey was performed. RESULTS: Down syndrome children presented a significantly greater percentage of children without caries, 78% vs. 58% of non-Down syndrome siblings. This difference in the DMFT index (number of decayed, missing and filled teeth) essentially reflects data obtained from treated teeth, for which 91% of children with Down syndrome had never had a tooth treated vs. 67% of siblings. This result was statistically significant, whereas results for decayed and lost teeth did not differ between Down syndrome children and their unaffected siblings. Additionally, in Down syndrome children, a delayed eruption of the second molar occurs. Down syndrome children and their siblings have similar oral hygiene habits, but a higher percentage of Down syndrome children visit a dentist before the age of three years, in comparison to their siblings. Bruxism was also more common in Down syndrome children compared to their siblings. CONCLUSIONS: Our results show that Portuguese children with Down syndrome have lower caries rates than children without Down syndrome. This reduced prevalence may be associated with the parents' greater concern about oral health care in Down syndrome children, resulting in their taking them sooner to visit a dentist, as well as to a higher bruxism prevalence and delayed tooth eruption.

This reduced prevalence may be associated with the parents' greater concern about oral health care in Down syndrome children, resulting in their taking them sooner to visit a dentist, as well as to a higher bruxism prevalence and delayed tooth eruption.

The Pemberton Happiness Index (PHI) is a recently developed integrative measure of well-being that includes components of hedonic, eudaimonic, social, and experienced well-being. The PHI has been validated in several languages, but not in Portuguese. Our aim was to cross-culturally adapt the Universal Portuguese version of the PHI and to assess its psychometric properties in a sample of the Brazilian population using online surveys.An expert committee evaluated 2 versions of the PHI previously translated into Portuguese by the original authors using a standardized form for assessment of semantic/idiomatic, cultural, and conceptual equivalence. A pretesting was conducted employing cognitive debriefing methods. In sequence, the expert committee evaluated all the documents and reached a final Universal Portuguese PHI version. For the evaluation of the psychometric properties, the data were collected using online surveys in a cross-sectional study. The study population included healthcare professionals and users of the social network site Facebook from several Brazilian geographic areas. In addition to the PHI, participants completed the Satisfaction with Life Scale (SWLS), Diener and Emmons' Positive and Negative Experience Scale (PNES), Psychological Well-being Scale (PWS), and the Subjective Happiness Scale (SHS). Internal consistency, convergent validity, known-group validity, and test-retest reliability were evaluated. Satisfaction with the previous day was correlated with the 10 items assessing experienced well-being using the Cramer V test. Additionally, a cut-off value of PHI to identify a "happy individual" was defined using receiver-operating characteristic (ROC) curve methodology.Data from 1035 Brazilian participants were analyzed (health professionals = 180; Facebook users = 855). Regarding reliability results, the internal consistency (Cronbach alpha = 0.890 and 0.914) and test-retest (intraclass correlation coefficient = 0.814) were both considered

Initiatives of identification, protection, and valuation of the Portuguese abiotic natural heritage have been carried out mainly by the scientific community, and particularly by the academic community. The official institutions responsible for nature conservation have focused their policies primarily on biodiversity issues and the relevance of geoconservation in the Portuguese geological survey was always minor, compared with homologous institutions from countries like Spain, for example. In this context, the academic community has led geoconservation research and activities in Portugal, especially since the late 1990s, following the development of this theme in the European continent. The first systematic inventory of the Portuguese geological heritage is a clear example of the academic collaboration that characterizes the geoconservation in Portugal. Three hundred and twenty six geosites with international or national relevance have been inventoried under the scope of the scientific research project "Identification, characterisation and conservation of geological heritage: a geoconservation strategy for Portugal", financed by the Portuguese Foundation for Science and Technology between 2007 and 2010 (PTDC/CTE-GEX/64966/2006). The inventory (one of the project's outputs) was coordinated by the University of Minho team with the participation of the universities of Algarve, Aveiro, Azores, Coimbra, Évora, Lisboa, Madeira, Nova de Lisboa, Porto, and Trás-os-Montes e Alto Douro. The inventory procedures were based on the ProGEO methodology, i.e., definition of geological frameworks followed by the identification of representative geosites with national and international relevance for each framework. The geosites were selected exclusively based on their scientific value and support twenty-seven frameworks. For each geological framework a leading geoscientist from a university was responsible for the scientific characterization of the framework, to invite

The aim of this study was to develop and validate a Portuguese version of The Subjective Experiences of Psychosis Scale (SEPS) for use in Portuguese-speaking populations in order to provide a self-report instrument to assess and monitor dimensions of psychotic experiences, translating patient's perspective and experience in terms of recovery from psychosis. The sample consisted of 30 participants with psychotic disorders who had recently experienced delusions or hallucinations. The SEPS was completed along with other observer-based assessments and self-report questionnaires, such as the Brief Psychiatric Rating Scale, the Insight and Treatment Attitudes Questionnaire and the Function Assessment Short Test. Two main factors representing the positive and negative components of each subscale were identified. We obtained good internal consistency and test-retest reliability for the positive and negative components of all subscales. The subscales of SEPS correlated with observer-based assessments and self-report questionnaires. The Portuguese version of the SEPS is a useful tool in the assessment and monitoring of psychotic symptoms.

The concept of quality of life is subjective and variable definition, which depends on the individual's perception of their state of health. Quality of life questionnaires are instruments designed to measure quality of life, but most are developed in a language other than Portuguese. Questionnaires can identify the most important symptoms, focus on consultation, and assist in defining the goals of treatment. Some of these have been validated for the Portuguese language, but none in children. To validate the translation with cross-cultural adaptation and validation of the Sinus and Nasal Quality of Life Survey (SN-5) into Portuguese. Prospective study of children aged 2-12 years with sinonasal symptoms of over 30 days. The study comprised two stages: (I) translation and cross-cultural adaptation of the SN-5 into Portuguese (SN-5p); and (II) validation of the SN5-p. Statistical analysis was performed to assess internal consistency, test-retest reliability, and sensitivity, as well as construct and discriminant validity and standardization. The SN-5 was translated and adapted into Portuguese (SN-5p) and the author of the original version approved the process. Validation was carried out by administration of the SN-5p to 51 pediatric patients with sinonasal complaints (mean age, 5.8±2.5 years; range, 2-12 years). The questionnaire exhibited adequate construct validity (0.62, p<0.01), internal consistency (Cronbach's alpha=0.73), and discriminant validity (p<0.01), as well as good test-retest reproducibility (Goodman-Kruskal gamma=0.957, p<0.001), good correlation with a visual analog scale (r=0.62, p<0.01), and sensitivity to change. This study reports the successful translation and cross-cultural adaptation of the SN-5 instrument into Brazilian Portuguese. The translated version exhibited adequate psychometric properties for assessment of disease-specific quality of life in pediatric patients with sinonasal complaints.

Clinical measurement. To translate and culturally adapt the Lower Extremity Functional Scale (LEFS) into a Brazilian Portuguese version, and to test the construct and content validity and reliability of this version in patients with knee injuries. There is no Brazilian Portuguese version of an instrument to assess the function of the lower extremity after orthopaedic injury. The translation of the original English version of the LEFS into a Brazilian Portuguese version was accomplished using standard guidelines and tested in 31 patients with knee injuries. Subsequently, 87 patients with a variety of knee disorders completed the Brazilian Portuguese LEFS, the Medical Outcomes Study 36-Item Short-Form Health Survey, the Western Ontario and McMaster Universities Osteoarthritis Index, and the International Knee Documentation Committee Subjective Knee Evaluation Form and a visual analog scale for pain. All patients were retested within 2 days to determine reliability of these measures. Validation was assessed by determining the level of association between the Brazilian Portuguese LEFS and the other outcome measures. Reliability was documented by calculating internal consistency, test-retest reliability, and standard error of measurement. The Brazilian Portuguese LEFS had a high level of association with the physical component of the Medical Outcomes Study 36-Item Short-Form Health Survey (r = 0.82), the Western Ontario and McMaster Universities Osteoarthritis Index (r = 0.87), the International Knee Documentation Committee Subjective Knee Evaluation Form (r = 0.82), and the pain visual analog scale (r = -0.60) (all, P<.05). The Brazilian Portuguese LEFS had a low level of association with the mental component of the Medical Outcomes Study 36-Item Short-Form Health Survey (r = 0.38, P<.05). The internal consistency (Cronbach α = .952) and test-retest reliability (intraclass correlation coefficient = 0.957) of the Brazilian Portuguese version of the LEFS were high. The

To explore the attitudes and perceptions of Portuguese residents towards Clinical Communication Skills (CCS) and the need for complementary training. 78 medical residents responded to an on-line questionnaire which comprised demographic data, open-ended questions and a Portuguese version of the Communication Skills Attitude Scale (CSAS). Residents gave significantly higher scores (P<0.001) on CSAS1 (attitudes towards communication skills in general, compared to CSAS2 (attitudes towards the teaching/learning process of CCS). Residents doing their residency training in other parts of the country, other than the north, reveal a higher perception of insufficient training (72.7% vs. 38.7%, P=0.036). Residents showed more positive attitudes towards communication skills than towards the teaching/learning process. They admit to need more training in CCS in their residency year and highlight that the clinical cycle of undergraduate education should integrate these topics. Content analysis indicates that residents' perceptions are context-influenced. Integration of CCS in the undergraduate education, enhanced during post-graduate training. Training of clinical faculty and supervisors/tutors and the role that stakeholders have to play in order to promote continuous training in CCS; encourage patient-centeredness and reflective practice, as to facilitate transfer of acquired skills to clinical practice.

The 7 point subjective global assessment (7p-SGA) and the malnutrition inflammation score (MIS) are tools commonly applied for the assessment of nutritional status in dialyzed patients. Both were developed in English and require translation to Portuguese to be applied in Brazil. The cross-cultural equivalence process ensures semantic and measurement equivalence of a translated tool. To perform the cross-cultural adaptation to Portuguese of the 7p-SGA and MIS. Semantic equivalence was performed by the back-translation method and by assessing the degree of similarity between the original instrument and that back-translated from Portuguese to English (Back-translation). The assessment of the equivalence measurement was made by evaluating the intern reliability (Cronbach's α) and interobserver reliability (two observers). One-hundred and one elderly patients on hemodialysis (HD) were included. Both instruments showed a high degree of semantic similarity with results close to the maximum value (7p-SGA 96.8 ± 7.8 and MIS 99.6 ± 1.4). The intern consistency showed a Cronbach's α value for 7p-SGA of 0.72 and of 0.53 for MIS. The interobserver reproducibility of 7p-SGA was moderate (intraclass coefficient [ICC] = 0.74 [95% CI: 0.58; 0.84]), while for MIS was strong (ICC = 0.88 [95% CI: 0.81; 0.93]). The 7p-SGA and MIS translated into Portuguese can be applied for assessing the nutritional status of elderly patients on HD. Studies testing the applicability of these instruments in adult patients on HD and in peritoneal dialysis should yet be performed.

Objective to investigate the performance of European Portuguese children in a Brazilian test of expressive vocabulary, seeking to identify differences between age groups and gender, and to verify its applicability in this population. Methods the sample consisted of 150 typical developed children, of both genders, between the ages of 5 and 6. All children attended public schools in the north area of Portugal. To assess the semantic performance, the expressive vocabulary sub-test of the language test (ABFW) was used, considering the percentage of usual verbal assignments and the classification (adequate/inadequate) according to the Brazilian reference values. Results the performance of the European Portuguese children indicated that at age 6 they have a higher percentage of correct answers in expressive vocabulary. As for the gender, there were only occasional differences: the girls showed a greater dominance in the semantic fields of clothing (both ages) and furniture and utensils (at age 5), whereas the boys showed more dominance in the semantic field means of transportation (6 years). Regarding classification, there was no difference between age groups in overall performance. Only the semantic field shapes and colors had more individuals of 6 years with inadequate performance. Conclusion the reference values adopted in the Brazilian population for semantic performance indicated that more than 80% of the children of each age group could have their performance classified as adequate. Such evidence suggests that this tool shows potential as an instrument of quantitative vocabulary's assessment of 5 and 6-years old children in European Portuguese.

Miranda do Douro, located in the northeastern region of Portugal, has notable characteristics not only from a geographic or naturalistic point of view, but also from a cultural perspective. A remarkable one is the coexistence of two different languages: Portuguese and Mirandese, the second being an Astur-Leonese dialect. The current persistence of the Astur-Leonese dialect in this population falls on the singularity of the region: relative isolation, implying difficulties to communicate with other Portuguese regions, while the same location facilitated the establishment of social and commercial relationships with adjacent Spanish territories, origin of the Astur-Leonese language. The objective of this study was to characterize the population from Miranda through the analysis of maternal lineages in order to evaluate whether its mitochondrial DNA diversity fitted the patterns previously reported for other populations from the Iberian Peninsula. Viewing that, the entire control region of mitochondrial DNA from 121 individuals was examined. Miranda showed a haplogroup composition usual for a Western European population, in the sense that as high as 63.6% of sequences belonged to macro-haplogroup R0. Lineages ascribed to have an African (L2a and L1b) origin, were detected, but reaching an amount commonly found in Portugal. Miranda also presented a few haplogroups typically found in Jewish populations, while rarely observed in other Iberian populations. The finding can be explained by gene flow with crypto-Jew communities that since long are known to be established in the region where Miranda is located. In Miranda, both genetic and nucleotide diversities presented low values (0.9292 ± 0.0180 and 0.01101 ± 0.00614 respectively) when compared to populations from its micro-geographical framework, which constitute a sign of population isolation that certainly provided conditions for the survival of the Astur-Leonese dialect in the region.

Obese individuals are often blamed for their own condition and the targets of discrimination and prejudice. The scope of this study is to describe the cross-cultural adaptation to Brazilian Portuguese and the validation of the Antifat Attitudes Test - specifically developed for evaluation of negative attitudes toward the obese individual. The scale has 34 statements distributed in three subscales - Social/Character Disparagement (15 items), Physical/Romantic Unattractiveness (10 items) and Weight Control/Blame (9 items). The method involved the translation of the scale; evaluation of the conceptual, operational and item equivalence; evaluation of the semantic equivalence using the paired t test, the Pearson correlation coefficient and the intraclass correlation coefficient (ICC); internal consistency evaluation (Cronbach's alpha) and test-retest reliability (ICC) and Confirmatory Factor Analysis - after application in 340 college students in the area of health. The results showed good global internal consistency and reliability (α 0.85; CCI 0.83), and factor analysis showed that the original subscales can be kept in the adaptation, and therefore the scale adapted to the Brazilian-Portuguese version is valid and useful in studies to explore negative attitudes toward obese individuals.

Did the corporatization of Portuguese hospitals significantly change their productivity?

2015-04-01

This paper aims to investigate if the market structure reforms in the Portuguese health system have improved hospital performance and productivity. A robust non-parametric Malmquist index is applied to measure group performance. The significance of the results achieved is examined using a conditional and non-conditional subsampling bootstrapped-based methodology, enhanced by the likelihood cross validation criterion based on the k-nearest neighbors method. The sample contains information about 216 non-corporatized and 176 corporatized Portuguese hospitals for the period 2002–2009. Five models were applied, based on three study dimensions (internment, emergencies and doctor visits). The results show that although corporatized hospitals presented the highest efficiency consistency, they had also the lowest levels of productivity, while the hospitals under the traditional administrative public management system were the ones with the best average performance. However, several best practices were also found in all groups, being the limited companies were often dominated by both noncorporatized and public enterprise entities. Consistent output ranges where all groups present dominance over the others were also identified. It was possible to conclude that the more autonomy the hospital had from the Ministry of Health, the lower was its productivity.

Despite Brazil's high levels of religious involvement, there is a scarcity of validated religiousness/spirituality (R/S) measures in Portuguese, particularly multidimensional ones. This study presents the validation of the Portuguese version of the "Brief Multidimensional Measure in Religiousness and Spirituality" (BMMRS) within the Brazilian context. Inpatients (262) and caregivers (389) at two hospitals of Brazil answered the BMMRS, the DUREL-p, and a sociodemographic questionnaire. The internal and convergent validity and test-retest reliability for major dimensions were good. Discriminant validity was high (except for the Forgiveness dimension). The Portuguese version of the BMMRS is a reliable and valid instrument to assess multiple R/S dimensions in clinical and non-clinical samples.

Head and neck cancer is the sixth leading cause of death from cancer worldwide and its treatment may involve surgery, chemotherapy and/or radiation therapy. The surgical procedure may cause mutilating sequelae, that can alter patient self-image. Thus, head and neck cancer is often connected to the negative stigma with decreased quality of life. Few studies assess the social stigma and shame perceived by patients with head and neck cancer. To perform the translation and cultural adaptation of the Shame and Stigma Scale (SSS) into Portuguese (Brazil). Two independent translations (English into Portuguese) were carried out by two professionals fluent in the English language. After the synthesis of the translations, two independent back-translations (from Portuguese into English) were performed by two translators whose native language is English. All translations were critically assessed by a committee of experts consisting of five members. A sample of 15 patients answered the Brazilian Portuguese version of the SSS to carry out the pretest. At this step, the patients were able to suggest modifications and evaluate the understanding of the items. There was no need to change the scale after this step. Based on the previous steps, we obtained the Portuguese (Brazil) version of the SSS, which was called "Escala de Vergonha e Estigma". The Portuguese (Brazil) version of the SSP was shown to be adequate to be applied to the population with HNC and, therefore, the psychometric properties of the tool will be evaluated during following steps.

Social and Emotional Learning (SEL) is an educational movement that is gaining ground throughout the world. We can define SEL as the capacity to recognize and manage emotions, solve problems effectively, and establish positive relationships with others. Research has demonstrated the significant role of SEL in promoting healthy student development and academic achievement. Extensive research confirms that SEL competencies: can be taught, that they promote positive development and reduce problem behaviors, and that they improve students' academic achievement and citizenship. At the international level, several rigorous studies have identified programs and practices that promote SEL. In Portugal, however, no review has yet been published regarding the implementation of SEL programs. Such a study would elucidate the current panorama of SEL programs in Portugal. This study aims to identify research on SEL programs implemented in Portuguese schools and the relationship of those programs with academic achievement. To this end, we have consulted the following databases: Scientific Repository of Open Access of Portugal (RCAAP), Online Knowledge Library (b-on), and Web of Science (WoS). The criteria were: (a) all time frames; (b) publications in either Portuguese or English; (c) programs that developed socio-emotional competencies in Portuguese schools; (d) academic levels including elementary, middle, and high school and (e) students of regular education. Few publications on SEL programs implemented in Portugal were found, although the recent decade has witnessed an upsurge of interest in the topic, principally that arising from academic research.

To determine the validity and reproducibility of a Portuguese-language version of the Chronic Respiratory Questionnaire (CRQ) in patients with COPD. A Portuguese-language version of the CRQ (provided by McMaster University, the holder of the questionnaire copyright) was applied to 50 patients with COPD (70 +/- 8 years of age; 32 males; FEV1 = 47 +/- 18% of predicted) on two occasions, one week apart. The CRQ has four domains (dyspnea, fatigue, emotional function, and mastery) and was applied as an interviewer-administered instrument. The Saint George's Respiratory Questionnaire (SGRQ), already validated for use in Brazil, was used as the criterion for validation. Spirometry and the six-minute walk test (6MWT) were performed to analyze the correlations with the CRQ scores. There were no significant CRQ test-retest differences (p > 0.05 for all domains). The test-retest intraclass correlation coefficient was 0.98, 0.97, 0.98 and 0.95 for the dyspnea, fatigue, emotional function and mastery domains, respectively. The Cronbach's alpha coefficient was 0.91. The CRQ domains correlated significantly with the SGRQ domains (-0.30 < r < -0.67; p < 0.05). There were no significant correlations between spirometric variables and the CRQ domains or between the CRQ domains and the 6MWT, with the exception of the fatigue domain (r = 0.30; p = 0.04). The Portuguese-language version of the CRQ proved to be reproducible and valid for use in Brazilian patients with COPD.

Research consistently demonstrates that positive student-teacher relationships are fundamental to the healthy development of all students. However, we lack a Portuguese-validated measure of student-teacher relationships. In this article we present the adaptation procedures and the psychometric properties of a Portuguese version of the Student-Teacher Relationship Scale - Short Form (Pianta, 1992). Five hundred and thirty five teachers from 127 schools completed the STRS-SF. The results demonstrate that this adapted version of the STRS-SF has good psychometric properties, namely high reliability (α = .84 to .87) and expected construct validity, which were tested through exploratory and confirmatory factor analyses (χ2/df = 1.65, CFI = .96, GFI = .93, RMSEA = 0.05). This study also showed that the correlations of student-teacher relationship with students' demographic variables are consistent with the evidence in the literature about this construct. Finally, the study indicated that female teachers reported more closeness, t(530) = 4.06, p < .001 and better overall student-teacher relationships, t(530) = 4.90, p < .001. In the discussion, we analyze the implications of these results.

There is little knowledge about how patients perceive and react to the extended role of community pharmacies. To develop a model describing the expanded role of Portuguese community pharmacies as comprising three roles - medicines supplier, advice provider and community health promoter - and two important patient reactions: satisfaction and loyalty. In 2010, 1200 face-to-face interviews were conducted with patients of community pharmacies in Portugal. A model comprising the three pharmacy roles and the two patient reactions was developed and tested using structural equation modelling. The results showed that the model was appropriate and that the roles of medicines supplier, advice provider and community health promoter were positively related to patients' satisfaction and loyalty. These results show that patients are aware of the different roles played by community pharmacies in Portugal. The data support the idea that the movement of Portuguese pharmacists' extended role, framed within a global context where society sends expectations regarding the role of organizations in the community in which they operate, is producing positive results for both patients and pharmacists. © 2014 John Wiley & Sons Ltd.

The present study analyzes the effect of age and amount of input in the acquisition of European Portuguese as a heritage language. An elicited production task centred on mood choice in complement clauses was applied to a group of fifty bilingual children (six- to sixteen-year-olds) who are acquiring Portuguese as a minority language in a German dominant environment. The results show a significant effect of the age at testing and the amount of input in the acquisition of the subjunctive. In general, acquisition is delayed with respect to monolinguals, even though higher convergence with the monolingual grammar is observed after twelve years of age. Results also reveal that children with more exposure to the heritage language at home show faster acquisition than children from mixed households: the eight- to nine-year-old age boundary seems relevant for those speakers with more exposure, and the twelve- to thirteen-year-old age boundary for those with less exposure.

Portuguese War Veterans: Moral Injury and Factors Related to Recovery From PTSD.

PubMed

Ferrajão, Paulo Correia; Aragão Oliveira, Rui

2016-01-01

This study explored the factors to which a sample of Portuguese war veterans attributed their recovery from posttraumatic stress disorder (PTSD). Participants were a sample of veterans (N = 60) with mental sequelae of the Portuguese Colonial War: 30 suffered from chronic PTSD (unrecovered) and 30 veterans with remission from PTSD (recovered). Two semistructured interviews were conducted. Analysis of the interviews was conducted using the Thematic and Categorical Analysis. Results showed that unrecovered participants reported higher postwar betrayal, appraisal of hostile societal homecoming, social stigmatization, lack of personal resources (mental fatigue and restriction of coping strategies), and reduced perceived social support. Recovered participants verbalized some capability for self-awareness of their own mental states and/or awareness of others' mental states (mentalization ability), a wider repertoire of coping strategies, and higher perceived social support. The authors discussed that recovery from PTSD among veterans can be related to the assimilation of moral injury by developing higher mentalization abilities. © The Author(s) 2015.

Empathy is an important concept in psychology and cognitive neuroscience. Despite the controversy around its definition, most researchers would agree that empathy is a multidimensional phenomenon which involves a vicarious experience of another person's affective state and an understanding of another person's affective experience. Self-report measures of empathy constitute an important tool for both research and clinical practice. The main goal of this study was to adapt and study the psychometric properties of the Questionnaire of Cognitive and Affective Empathy (QCAE), a worldwide used measure of empathy, in a Portuguese community sample (N = 562). Confirmatory factor analyses supported the factor structure of the original QCAE. Results show that the Portuguese version of the QCAE has sound psychometric properties, with good structural validity and internal consistency for both scales (i.e., affective and cognitive) and respective subscales of the instrument (i.e., Emotion Contagion, Proximal Responsivity, Peripheral Responsivity, Perspective Taking and Online Simulation). We tested both a five correlated factor structure (Model 1) and a second-order model that postulates the affective and cognitive dimensions (Model 2). Our results show that while both models present acceptable goodness of fit indices, Model 1 performs slightly better. In conclusion, the Portuguese version of the QCAE may prove a useful tool for future cross-cultural assessments of empathy in both research and clinical practice.

The aim of this study was to examine the relationship between participation motives and level of practice in young Portuguese swimmers and to investigate whether swimmers with a different expertise differ in their reasons for participation involvement. A total of 155 subjects (68 male and 87 female), aged 7 to 18 years, responded to the Portuguese versions of the Participation Motivation Inventory. The subjects were divided into those participating in learn-to swim programs (n=40), advanced programs (n=49) or competition (n=56). A significant multivariate effect was obtained for level of practice, with children involved in learn-to swim programs rating fitness, competition, general affiliation, technical skills and fun significantly lower in importance than the other two groups. A 2 (subject gender) x3 (practice level) MANCOVA, with age at dropout, revealed that the effect of the covariate itself was not significant, but a main effect was found for gender, differing boys and girls only in the emotion factor. A significant interaction was also detected between gender and participation level, with a higher importance given to general affiliation by girls in comparison to boys in the advanced programs and competition categories. Our results in a sample of Portuguese swimmers indicate the existence of multiple motives for participation and significant differences in motivational factors in relation to the practice level.

This study aimed to perform the cross-cultural adaptation and validation of the Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health scale in the Portuguese language. The ten Global Health items were cross-culturally adapted by the method proposed in the Functional Assessment of Chronic Illness Therapy (FACIT). The instrument's final version in Portuguese was self-administered by 1,010 participants in Brazil. The scale's precision was verified by floor and ceiling effects analysis, reliability of internal consistency, and test-retest reliability. Exploratory and confirmatory factor analyses were used to assess the construct's validity and instrument's dimensionality. Calibration of the items used the Gradual Response Model proposed by Samejima. Four global items required adjustments after the pretest. Analysis of the psychometric properties showed that the Global Health scale has good reliability, with Cronbach's alpha of 0.83 and intra-class correlation of 0.89. Exploratory and confirmatory factor analyses showed good fit in the previously established two-dimensional model. The Global Physical Health and Global Mental Health scale showed good latent trait coverage according to the Gradual Response Model. The PROMIS Global Health items showed equivalence in Portuguese compared to the original version and satisfactory psychometric properties for application in clinical practice and research in the Brazilian population.

Objective: translate and validate to Portuguese the Scale of Student Satisfaction and Self-Confidence in Learning. Material and Methods: methodological translation and validation study of a research tool. After following all steps of the translation process, for the validation process, the event III Workshop Brazil - Portugal: Care Delivery to Critical Patients was created, promoted by one Brazilian and another Portuguese teaching institution. Results: 103 nurses participated. As to the validity and reliability of the scale, the correlation pattern between the variables, the sampling adequacy test (Kaiser-Meyer-Olkin) and the sphericity test (Bartlett) showed good results. In the exploratory factorial analysis (Varimax), item 9 behaved better in factor 1 (Satisfaction) than in factor 2 (Self-confidence in learning). The internal consistency (Cronbach's alpha) showed coefficients of 0.86 in factor 1 with six items and 0.77 for factor 2 with 07 items. Conclusion: in Portuguese this tool was called: Escala de Satisfação de Estudantes e Autoconfiança na Aprendizagem. The results found good psychometric properties and a good potential use. The sampling size and specificity are limitations of this study, but future studies will contribute to consolidate the validity of the scale and strengthen its potential use. PMID:26625990

The real life effectiveness, safety and the use of omalizumab for Portuguese patients with uncontrolled persistent allergic asthma are not sufficiently well known. The objective of this report was to make an evaluation, in a post-marketing, non-interventional, observational registry, of the Portuguese population included in the eXpeRience study. The methods used in this report are the same as the global eXpeRience ones, applied to a Portuguese sub-population. Patients with uncontrolled allergic asthma who had started omalizumab within the previous 15 weeks were enrolled and received omalizumab add-on therapy for 24 months. The physicians' global evaluation of treatment effectiveness (GETE), asthma symptoms and control (ACT score), quality of life (mini-AQLQ score), exacerbations, and serious adverse events (SAE) were reported. Of the 943 patients recruited in the eXpeRience registry, 62 patients were from Portugal. 62.1% of them were observed to be responders with good/excellent GETE assessment at Week 16. Clinically meaningful improvements in asthma control (ACT score) and quality of life (mini-AQLQ score) were observed with omalizumab therapy at Months 12 (mean change: +7.7 [n=35]; +2.1 [n=20], respectively) and 24 (mean change: +7.0 [n=26]; +2.7 [n=13], respectively). Asthma symptoms and rescue medication usage were reduced to ≤1 day/week at Month 24 from a baseline of ≥3.5 days/week. The proportion of patients with no clinically significant exacerbations increased from 6.5% during pre-treatment (n=62) to 50% at Month 12 (n=54) and 60% at Month 24 (n=45). The findings from the Portugal subpopulation of eXpeRience registry confirm that omalizumab add-on therapy is efficacious and well tolerated in the management of uncontrolled persistent allergic asthma. Another pertinent issue is the fact that the Portuguese subpopulation response is similar to the international population average of the study. Copyright © 2014 Sociedade Portuguesa de Pneumologia

Quinta Gomes, Ana Luísa; Nobre, Pedro

2012-01-01

The International Index of Erectile Function (IIEF) is a brief, reliable, and multidimensional scale for assessing sexual function in men in both research and clinical trials. The objective of the present study was to determine the psychometric properties of the Portuguese version of the IIEF. A total of 1,363 Portuguese men participated in this study (a clinical sample of 37 men and a community sample of 1,326 men). All participants completed a questionnaire regarding demographic information and the IIEF. Principal component analysis using varimax rotation indicated a two-factor structure explaining approximately 55% of the total variance (one factor encompassing erection and orgasmic function domains of the original IIEF, and a second factor corresponding to sexual desire, intercourse, and overall satisfaction). The differentiated factor structure with five separate domains of sexual function was not replicated in the Portuguese version. The two-factor model and the original five-factor model of male sexual function were assessed with confirmatory factor analysis (CFA), and overall acceptable fits were demonstrated for both models. However, despite a non-optimal performance, CFA provided a better support for the five-factor solution as the model that best fitted the data. An important lack of discriminant validity evidenced by high intercorrelations among dimensions was detected in both models, suggesting a substantial overlap among factors. Reliability studies showed good internal consistency for the five subscales, and test-retest reliability analysis supported the stability of the measure over time. Discriminant validity confirmed the ability of both subscales to differentiate men with erectile dysfunction from matched controls. Results suggested that the Portuguese version of the IIEF has adequate psychometric properties, and its use is recommended for clinical and research purposes. Further studies are needed in order to elucidate the association among

Functional, Sensorial, Mobility and Communication Difficulties in the Portuguese Oldest Old (80+).

The ageing of populations is evident in most developed countries, and the oldest old group is one of the segments with the fastest growing. The aim of this paper is to examine sociodemographic and health related characteristics of the portuguese oldest old, using a census-based approach. A descriptive study considering all residents aged 80 years and older at the time of the 2011 Census (n = 532 219) was conducted. Information on sociodemographic characteristics, sensory functions (seeing, hearing), functional status (walking/climbing stairs, bathing/dressing alone), cognition (memory/concentration), and communication (understanding others/being understood) as assessed by the Portuguese census official questionnaires were analyzed. Findings revealed that most of the oldest old are women (64.5%), widowed (53.9%), illiterate (46.1%) and live in private households (88.8%). Walking/climbing stairs (57.1%), vision (39.1%) and hearing (35.1%) were the dimensions where the oldest old presented major constrains. In parallel, understanding others/being understood (25.9%) and memory/concentration (34.4%) were the dimensions with lower percentages of difficulties. Significant differences were found between octogenarians/nonagenarians and centenarians for vision, walk/climb stairs, and bathing/dressing alone, with centenarians presenting a higher percentage of difficulties. Portuguese oldest old showed significant difficulties in activities of daily living, nevertheless cognitive and communication capacities seem to be commonly maintained. Taken together, these findings suggest the need for functional assistance, which can be ultimately managed by the older person him/herself. Based on the observed differences between centenarians and younger oldest old, specific interventions should be equated to better respond to their potentially distinctive needs.

Establishing the Bases for Introducing the Unexplored Portuguese Common Bean Germplasm into the Breeding World.

Common bean ( Phaseolus vulgaris L.) is among the most important grain legumes for human consumption worldwide. Portugal has a potentially promising common bean germplasm, resulting from more than five centuries of natural adaptation and farmers' selection. Nevertheless, limited characterization of this resource hampers its exploitation by breeding programs. To support a more efficient conservation of the national bean germplasm and promote its use in crop improvement, we performed, for the first time, a simultaneous molecular marker (21 microsatellites and a DNA marker for phaseolin-type diversity analysis) and seed and plant morphological characterization (14 traits) of 175 accessions from Portuguese mainland and islands traditional bean-growing regions. A total of 188 different alleles were identified and an average pairwise Cavalli-Sforza and Edwards' chord genetic distance of 0.193 was estimated among accessions. To relate the Portuguese germplasm with the global common bean diversity, 17 wild relatives and representative accessions from the Andean and Mesoamerican gene pools were evaluated at the molecular level. No correlation was detected between the variability found and the geographic origin of accessions. Structure analysis divided the collection into three main clusters. Most of the Portuguese accessions grouped with the race representatives and wild relatives from the Andean region. One third of the national germplasm had admixed genetic origin and might represent putative hybrids among gene pools from the two original centers of domestication in the Andes and Mesoamerica. The molecular marker-based classification was largely congruent with the three most frequent phaseolin haplotype patterns observed in the accessions analyzed. Seed and plant morphological characterization of 150 Portuguese common bean accessions revealed a clear separation among genetic structure and phaseolin haplotype groups of accessions, with seed size and shape and the number of

Risk Levels of Toxic Cyanobacteria in Portuguese Recreational Freshwaters

Menezes, Carina; Dias, Elsa

2017-01-01

Portuguese freshwater reservoirs are important socio-economic resources, namely for recreational use. National legislation concerning bathing waters does not include mandatory levels or guidelines for cyanobacteria and cyanotoxins. This is an issue of concern since cyanotoxin-based evidence is insufficient to change the law, and the collection of scientific evidence has been hampered by the lack of regulatory levels for cyanotoxins in bathing waters. In this work, we evaluate the profile of cyanobacteria and microcystins (MC) in eight freshwater reservoirs from the center of Portugal, used for bathing/recreation, in order to determine the risk levels concerning toxic cyanobacteria occurrence. Three of the reservoirs did not pose a risk of MC contamination. However, two reservoirs presented a high risk in 7% of the samples according to the World Health Organization (WHO) guidelines for MC in bathing waters (above 20 µg/L). In the remaining three reservoirs, the risk concerning microcystins occurrence was low. However, they exhibited recurrent blooms and persistent contamination with MC up to 4 µg/L. Thus, the risk of exposure to MC and potential acute and/or chronic health outcomes should not be disregarded in these reservoirs. These results contribute to characterize the cyanobacterial blooms profile and to map the risk of toxic cyanobacteria and microcystins occurrence in Portuguese inland waters. PMID:29057822

The aim of this study is the cross-cultural, as well as to validate in Portuguese language the Amyotrophic Lateral Sclerosis Functional Rating Scale - Revised (ALSFRS-R). We performed a prospective study of individuals with amyotrophic lateral sclerosis (ALS) clinically defined. The scale, after obtaining the final version in Portuguese, was administered in 22 individuals and three weeks after re-applied. There were no significant differences between the application and reapplication of the scale (p=0.069). The linear regression and internal consistency measured by Pearson correlation and alpha Conbrach were significant with r=0.975 e alpha=0.934. The reliability test-retest demonstrated by intraclass correlation coefficient was strong with ICC=0.975. Therefore, this version proved to be applicable, reliable and easy to be conducted in clinical practice and research.

Blood pressure is significantly improved with weight loss. Behavioral interventions for weight loss seem to be less successful in African immigrants. Our main aims were to assess the effect of a dietary and lifestyle intervention on weight among hypertensive Portuguese natives and immigrants and to identify success factors for weight loss, and also to evaluate changes in knowledge and compliance with food recommendations. Hypertensive medicated patients followed in primary care setting were randomly enrolled in a two phase study, observational (15-months) and behavioral intervention (six months). Participants were divided in two groups: immigrants from African Countries of Portuguese Official Language and Portuguese natives. Participants were given dietary and life styles recommendations in individual face-to-face and telephone sessions. Of 110 participants with a mean BMI of 31.6 ± 3.7 Kg/m(2), 60 were immigrants. The number of dietary recommendations known and followed at the end was significantly greater than at baseline; however natives performed a greater number of recommendations. Weight loss during intervention was in average 1.4 ± 2.7% in natives and 0.8 ± 3.6% in immigrants and was greater than in the observational period. Being male and consuming more than 2 servings of low-fat dairy products/day was associated with higher weight loss, independently of age and ethnicity. In general the proposed intervention was efficacious especially in Portuguese natives, confirming other studies. The intervention increased knowledge and adherence to recommendations, highlighting the relevance of nutrition education, culturally adapted in primary care.

Diabetic peripheral neuropathy is very common in the diabetic population. Early screening for foot pathology is of the utmost importance. The Michigan Neuropathy Screening Instrument (MNSI) is an easy, brief, and noninvasive screening tool. The aim of this study was to validate the semantics and characteristics of both sections of the Portuguese translation of the MNSI for Portuguese diabetic patients. A cross-sectional study was performed on 87 type 1 and 2 diabetic patients at our outpatient endocrinology department. The final sample was composed of 76 patients. Nerve conduction studies were requested, but only a subsample of 42 patients agreed to participate in them. The scale was internally consistent (Cronbach's alpha > 0.70 in section A, or a clinical history questionnaire and a physical examination [section B]), and the scores of both sections were positively correlated (r = 0.70; P < 0.001). With regard to stability, MNSI scores between test/retest showed high stability (intraclass correlation coefficient = 0.91). The receiver-operating characteristic (ROC) demonstrated its validity, with ROC curve values for section A, section B, and sections A + B of 0.913, 0.798, and 0.906 respectively. Considering a cut off of ≥ 3 in section A and of ≥ 2 in section B, we obtained a sensitivity of 100% and 86%; a specificity of 64% and 61%; a positive predictive value of 80% and 73%; and a negative predictive value of 100% and 79%, respectively. The Portuguese MNSI is a reliable and valid tool for screening diabetic neuropathy. © 2016 World Institute of Pain.

Consistent evidence exist on the harmful health effects of industrial trans fatty acids (TFA). In order to have accurate data on TFA intake and implement adequate measures to reduce their intake, each country should have updated estimates of TFA content in the diet. The objective of the present study was to provide data on the TFA content in food commercialized in the Portuguese market. The results on the TFA content of 268 samples acquired between October and December 2013 are reported. Samples were categorized as margarines and shortenings (n = 16), spreadable chocolate fats (n = 6), fried potatoes and chips (n = 25), industrial bakery (n = 4), breakfast cereals (n = 3), pastry products (n = 120), seasonings (n = 5), instant soups (n = 5), instant desserts (n = 6), chocolate snacks (n = 4), microwave popcorn (n = 4), cookies, biscuits and wafers (n = 53), and fast-food (n = 13), with butter (n = 4) included for comparison purposes. TFA were quantified by gas chromatography. Total TFA content in the fat ranged from 0.06% to 30.2% (average 1.9%), with the highest average values in the "biscuits, wafers and cookies" group (3.4% TFA), followed by the pastry group (2.0%). Fifty samples (19%) had TFA superior to 2% in the fat. These findings highlight there is still much need for improvement in terms of the TFA content in Portuguese foods, particularly in traditional pastry.

Samples were categorized as margarines and shortenings (n = 16), spreadable chocolate fats (n = 6), fried potatoes and chips (n = 25), industrial bakery (n = 4), breakfast cereals (n = 3), pastry products (n = 120), seasonings (n = 5), instant soups (n = 5), instant desserts (n = 6), chocolate snacks (n = 4), microwave popcorn (n = 4), cookies, biscuits and wafers (n = 53), and fast-food (n = 13), with butter (n = 4) included for comparison purposes. TFA were quantified by gas chromatography. Total TFA content in the fat ranged from 0.06% to 30.2% (average 1.9%), with the highest average values in the “biscuits, wafers and cookies” group (3.4% TFA), followed by the pastry group (2.0%). Fifty samples (19%) had TFA superior to 2% in the fat. These findings highlight there is still much need for improvement in terms of the TFA content in Portuguese foods, particularly in traditional pastry. PMID:27274619

Recently, the Obstructed Defecation Syndrome score (ODS score) was developed and validated by Renzi to assess clinical staging and to allow evaluation and comparison of the efficacy of treatment of this disorder. Our goal is to validate the Portuguese version of Renzi ODS score, according to the Consensus based Standards for the selection of the Health Measurement Instruments (COSMIN) checklist. Following guidelines for cross-cultural validity, Renzi ODS score was translated into the Portuguese language. Then, a group of patients and healthy controls were invited to fill in the Renzi ODS score at baseline, after 2 weeks and 3 months, respectively. We assessed internal consistency, reliability and measurement error, content and construct validity, responsiveness and interpretability. A total of 113 individuals (77 patients; 36 healthy controls) completed the questionnaire. Seventy and 30 patients repeated the Renzi ODS score after 2 weeks and 3 months respectively. Factor analysis confirmed the unidimensionality of the scale. Cronbach's α coefficient of 0.77 supported item's homogeneity. Weighted quadratic kappa of 0.89 established test-retest reliability. The smallest detectable change at the individual level was 2.66 and at the group level was 0.30. Renzi ODS score and the total (-0.32) and physical (-0.43) SF-36 scores correlated negatively. Patient and control's groups significantly differed (11 points). The change score of Renzi ODS score between baseline and 3 months correlated negatively with the clinical evolution (-0.86). ROC analysis showed minimal important change of 2.00 with AUC 0.97. Neither floor nor ceiling effects were observed. This work validated the Portuguese version of Renzi ODS score. We can now use this reliable, responsive, and interpretable (at the group level) tool to evaluate Portuguese ODS patients.

The objective of this study was to translate and culturally adapt the Behavioral Pain Scale to Brazilian Portuguese and to evaluate the psychometric properties of this scale. This study was conducted in two phases: the Behavioral Pain Scale was translated and culturally adapted to Brazilian Portuguese and the psychometric properties of this scale were subsequently assessed (reliability and clinical utility). The study sample consisted of 100 patients who were older than 18 years of age, admitted to an intensive care unit, intubated, mechanically ventilated, and subjected or not to sedation and analgesia from July 2012 to December 2012. Pediatric and non-intubated patients were excluded. The study was conducted at a large private hospital that was situated in the city of São Paulo (SP). Regarding reproducibility, the results revealed that the observed agreement between the two evaluators was 92.08% for the pain descriptor "adaptation to mechanical ventilation", 88.1% for "upper limbs", and 90.1% for "facial expression". The kappa coefficient of agreement for "adaptation to mechanical ventilation" assumed a value of 0.740. Good agreement was observed between the evaluators with an intraclass correlation coefficient of 0.807 (95% confidence interval: 0.727-0.866). The Behavioral Pain Scale was easy to administer and reproduce. Additionally, this scale had adequate internal consistency. The Behavioral Pain Scale was satisfactorily adapted to Brazilian Portuguese for the assessment of pain in critically ill patients.

The importance of quickly assessing personality traits in many studies prompted the development of brief scales such as the Ten-Item Personality Inventory (TIPI), a measure of five personality traits (extraversion, agreeableness, conscientiousness, emotional stability, and openness). In the current study, we present the Portuguese version of TIPI and examine its psychometric properties, based on a sample of 333 Portuguese adults aged 18 to 65 years. The results revealed reliability coefficients similar to the original version (α = 0.39-0.72), very good 4-week test-retest reliability ( n = 81, r s > 0.71), expected factorial structure, high convergent validity with the Big-Five Inventory ( r s > 0.60), and correlations with self-esteem, affect, and aggressiveness similar to those found with standard measures of personality traits. Overall, our findings suggest that the Portuguese TIPI is a reliable and valid alternative to longer measures: it offers a promising tool for research contexts in which the available time for personality assessment is highly limited.

Indoor air quality recently entered legislation in Portugal. Several parameters must be evaluated and kept within limits in order to obtain a certification for air quality and energy consumption. Certification parameters were analyzed in two Portuguese archives in order to assess indoor air quality both for people attending or working on these premises and for maintenance of a written heritage that must be retained for future generations. Carbon monoxide (CO) and carbon dioxide (CO₂), formaldehyde, and fungal counts were kept within stipulated limits. Relative humidity (RH), volatile organic compounds (VOC), particulate matter (PM₁₀), and ozone (O₃) showed values above legislated levels and justified the implementation of corrective measures. In terms of conservation, studies on the limit values are still needed, but according to the available international guidelines, some of the analyzed parameters such as PM₁₀, O₃, and RH were also above desirable values. Corrective measures were proposed to these institutions. Although this study was only of a short duration, it proved valuable in assessing potential eventual problems and constitutes the first Portuguese indoor air quality assessment taking into consideration both aspects of an archive such as human health and heritage safekeeping.

The Portuguese coast presents a large amount of potentially edible seaweeds that are underexploited. The identification of different macroalgae species and their availability in the northern and central coast of the continental territory was assessed. The nutritional value of seaweeds is discussed based on a literature review (when available) focused on data for species collected in Portugal with the aim to define the most important nutritional parameters that should be characterized in the samples. Possible health concerns related with the presence of contaminants are also considered.

The scope of this study was the validation of a cross-culturally adapted questionnaire into Portuguese in five community pharmacies in Portugal. The discriminatory power of items, content and construct validity and factor analysis of the main components and their reliability and stability were determined. A high degree of semantic equivalence between the original questionnaire and the cross-culturally adapted questionnaire into Portuguese was observed. A Kaiser-Meyer-Olkin index of 0.550 was obtained and the Bartlett sphericity test confirmed the adequacy of the data for the application of factor analysis (p <0.0001). Three factors which accounted for 52.6% of the total variability were considered. With respect to reliability the following results were obtained: 0.519 for Cronbach's alpha test; 0.89 for Cohen's kappa coefficient; and 0.756 (IC=0.598-0.963) for the CCI exam. In this work, the first adaptation for the Portuguese culture of a specific questionnaire was produced to measure the degree of knowledge patients have about their medication.

To perform the translation and cultural adaptation of the Aguado Syntax Test (AST) into Brazilian Portuguese considering the linguistic and cultural reality of the language. The AST assesses the early morphosyntactic development in children aged 3 to 7 in terms of understanding and expression of various types of structures such as sentences, pronouns, verbal voices, comparisons, prepositions and verbal desinence as to number, mode and tense. The process of translation and cultural adaptation followed four steps: 1) preparation of two translations; 2) synthesis of consensual translations; 3) backtranslation; and 4) verification of equivalence between the initial translations and backtranslations that resulted in the final translated version. The whole process of translation and cultural adaptation revealed the presence of equivalence and reconciliation of the translated items and an almost complete semantic equivalence between the two translations and the absence of consistent translation difficulties. The AST was translated and culturally adapted into Brazilian Portuguese, constituting the first step towards validation and standardization of the test.

A cross-cultural translation of the Vespid Allergy Quality of Life Questionnaire (VQLQ) to the Portuguese population (VQLQ-P) was performed, assessing its applicability in wasp and in non-beekeeper bee venom allergic patients. Additionally, we evaluated a Visual Analogue Scale (VAS) to estimate hymenoptera allergy interference with daily life. Methods. Cross-cultural translation was performed according to recommendations. The final VQLQ-P version, the Expectation of Outcome questionnaire (EoQ), EQ-5D and VAS were applied to wasp (n = 19) and non-beekeeper bee venom allergic patients (n = 30). Results. VQLQ-P significantly correlated with EoQ, (r = 0.76, p < 0.01), EQ-5D (usual activities and anxiety / depression dimensions) and VAS, with a good internal consistency (Cronbach α = 0.88) in wasp allergic individuals. VQLQ-P and EoQ correlation was also high (r = 0.67, p < 0.01) in bee allergy. Conclusion. The VQLQ-P is a valuable tool to evaluate quality of life impairment in Portuguese hymenoptera venom allergic individuals.

A global effort has been made in the last years to establish a set of core competences that define the essential professional competence of a physician. Regardless of the environment, culture or medical education conditions, a set of core competences is required for medical practice worldwide. Evaluation of educational program is always needed to assure the best training for medical students and ultimately best care for patients. The aim of this study was to determine in what extent medical students in Portugal and Portuguese speaking African countries, felt they have acquired the core competences to start their clinical practice. For this reason, it was created a measurement tool to evaluate self-perceived competences, in different domains, across Portuguese and Portuguese-speaking African medical schools. The information was collected through a questionnaire that defines the knowledge, attitudes and skills that future doctors should acquire. The Cronbach's Alpha and Principal Components Analysis (PCA) were used to evaluate the reliability of the questionnaire. In order to remove possible confounding effect, individual scores were standardized by country. The order of the domain's scores was similar between countries. After standardization, Personal Attitudes and Professional Behavior showed median scores above the country global median and Knowledge alone showed median score below the country global median. In Portugal, Clinical Skills showed score below the global median. In Angola, Clinical Skills and General Skills showed a similar result. There were only significant differences between countries in Personal Attitudes (p < 0.001) and Professional Behavior (p = 0.043). The reliability of the instrument in Portuguese and Portuguese-speaking African medical schools was confirmed. Students have perceived their level of competence in personal attitudes in a high level and in opposite, knowledge and clinical skills with some weaknesses.

This controlled pre-post study investigated whether a universal, school-based, social-emotional learning program implemented in two consecutive school years in two distinct cohorts, would promote gains in the social-emotional competencies of Portuguese middle school students. Moreover, it also analyzed the moderating role of students' characteristics, such as gender and baseline levels, on the impact of the intervention. Program 'Positive Attitude' was applied to 472 seventh to ninth grade students (25 classes). One hundred and fifty-six students in control groups (8 classes) also participated in this study. Overall, there were 628 participants aged from 11 to 17 years (Mage = 13.54; SD = 1.36). Self-report questionnaires were administered before and after the intervention. There were significant intervention gains in three (of five) social-emotional competencies, namely increases in social awareness and self-control as well as decreases in the levels of social anxiety in the first cohort. The positive effects were stably effective in the second cohort, except for social anxiety. Girls revealed greater gains in social awareness and greater reductions of the levels of social isolation and social anxiety when compared with boys. Intervention students with lower social awareness pretest scores profited more than controls. These results indicated that the intervention improved the social and emotional competencies of middle school students, supporting the cross-cultural generalization of social-emotional learning programs' efficacy. © The Author 2015.

With the advent of surfactant, prenatal corticosteroids (PNC) and advances in technology, the survival rate of extremely low birth weight (ELBW) infants has improved dramatically. Rates of bronchopulmonary dysplasia (BPD) vary widely among neonatal intensive care units (NICUs) and many studies using multiple interventions have shown some improvement in BPD rates. Implementing potentially better practices to reduce BPD has been an effort made over the last few decades. To compare five Portuguese NICUs in terms of clinical practices in very low birth weight (VLBW) infants, in order to develop better practices to prevent BPD. 256 preterm neonates, gestational age (GA) <30 weeks and/or birthweight (BW) <1250g admitted to five Portuguese NICUs (centers 1 to 5) between 1st January 2004 and 31st December 2006, were studied. VLBW infants with major malformations, grade IV intraventricular haemorrhage in the first week of life and metabolic or neuromuscular disease were excluded. BPD was defined as oxygen dependency at 36 weeks of postconceptional age. We considered a practice to be improved as clinically significant whenever a decrease greater than 10% in the prevalence of BPD adjusted for the practice, GA and BW was achieved compared to BPD prevalence adjusted only for GA and BW. The overall prevalence of BPD was 12.9%. Our results revealed that PNC use should be improved in centers 4 and 5; fluid policy in center 4; oxygen therapy and sepsis prevention in centers 1 and 2. Patent ductus arteriosus (PDA) treatment should be improved in center 2. The implementation of potentially better practices to reduce lung injury in neonates in Portuguese NICUs, according to each NICU, must be addressed to increase the prescription of PNC, to use a lower FiO2, to be careful with fluid administration in the first weeks of life and to prevent PDA and sepsis. It is necessary to follow guidelines, recommendations or protocols to improve quality in the prevention of BPD.

The pinewood nematode, Bursaphelenchus xylophilus, is native to North America but it only causes damaging pine wilt disease in those regions of the world where it has been introduced. The accurate detection of the species and its dispersal routes are thus essential to define effective control measures. The main goals of this study were to analyse the genetic diversity among B. xylophilus isolates from different geographic locations and identify single nucleotide polymorphism (SNPs) markers for geographic origin, through a comparative transcriptomic approach. The transcriptomes of seven B. xylophilus isolates, from Continental Portugal (4), China (1), Japan (1) and USA (1), were sequenced in the next generation platform Roche 454. Analysis of effector gene transcripts revealed inter-isolate nucleotide diversity that was validated by Sanger sequencing in the genomic DNA of the seven isolates and eight additional isolates from different geographic locations: Madeira Island (2), China (1), USA (1), Japan (2) and South Korea (2). The analysis identified 136 polymorphic positions in 10 effector transcripts. Pairwise comparison of the 136 SNPs through Neighbor-Joining and the Maximum Likelihood methods and 5-mer frequency analysis with the alignment-independent bilinear multivariate modelling approach correlated the SNPs with the isolates geographic origin. Furthermore, the SNP analysis indicated a closer proximity of the Portuguese isolates to the Korean and Chinese isolates than to the Japanese or American isolates. Each geographic cluster carried exclusive alleles that can be used as SNP markers for B. xylophilus isolate identification. PMID:24391785

The inability of traditional state organisations to respond to new economic, technological and social challenges and the associated emerging problems has made it necessary to adopt new methods of health management. As a result, new directions have emerged in the reform of Public Administration together with the introduction of innovative models. The aim is to achieve a type of management that focuses on results as well as on effort and efficiency. We intend to analyse to what extent the adoption of business management models by hospital healthcare units can improve their performance, mainly in terms of standards of efficiency. Data envelopment analysis (DEA) was used to investigate the efficiency of a set of public Portuguese hospitals. The aim was to evaluate the impact of business management in Portuguese public hospitals with regards to efficiency, specifically taking into account the fact that lack of resources and increased health care needs are a present and future reality. From a total of 83 public hospitals, a sample of 59 hospitals was chosen, of which 21 are state-owned hospital enterprises (SA) and 38 are traditional public administration sector hospitals (SPA). This study evaluates hospital performance by calculating two efficiency measures associated with two categories of inputs. The first efficiency measures the costs associated with hospital production lines and the number of beds (representing fixed capacity) as inputs. The annual costs generated by the hospitals in the consumption of capital and work (direct and indirect costs) are used. A second measure of efficiency is calculated separately. This measure includes in the inputs the number of beds as well as the human resources available (number of doctors, number of nurses and other personnel) in each hospital. With regard to output, the variables that best reflect the hospital services rendered were considered: number of inpatient days, patients discharged, outpatient visits, emergencies

The aim of the present study was to evaluate the genetic variation of Pneumocystis jirovecii dihydrofolate reductase (DHFR) gene in an immunocompromised Portuguese population and to investigate the possible association between DHFR genotypes and P. jirovecii pneumonia (PcP) prophylaxis with co-trimoxazole. One hundred and thirty-eight P. jirovecii isolates were submitted to DHFR genetic characterization by PCR and sequencing. In the studied population, 72.7% of the patients presented sequences identical to the wild-type sequence of the P. jirovecii DHFR gene and 27.3% presented point substitutions. A total of nine substitution sites were identified; four synonymous substitutions at nucleotide positions 201, 272, 312 and 381 were detected in 31 patients. Five non-synonymous substitutions were observed, leading to the DHFR mutations Leu-13-->Ser, Asn-23-->Ser, Ser-31-->Phe, Met-52-->Leu and Ala-67-->Val. With the exception of the polymorphism at position 312 and the mutation at codon 52, all polymorphisms were reported in this study for the first time. Our results suggest that DHFR gene polymorphisms are frequent in the Portuguese immunocompromised population but do not seem to be associated with PcP prophylaxis failure (P = 0.748 and P = 0.730).

2003-11-01

We analyzed the genetic variation among isolates of Pneumocystis jiroveci from Portuguese immunocompromised patients with PCP at the internal transcribed spacer (ITS) regions of the nuclear rRNA operon and at the dihydropteroate synthase (DHPS) gene. Pulmonary secretions from 42 patients with PCP corresponding to 43 episodes were studied. Demographic, immunological, and clinical data were obtained from all patients. By combining the two regions ITS1 and ITS2, we found 17 different ITS types of P. jiroveci, two of them were new types (Pb and Pe). The four most prevalent ITS types were Eg (23.3%), Eb and Ne (11.6% each), and Bi (9.3%). A single type was detected in 95.3% of the samples and 4.7% had mixed infections with three different ITS types. DHPS mutants were present in 17 (46%), and the wildtype was present in 20 (54%) of 37 isolates. No association was found between ITS and DHPS types and between DHPS types and therapy or response to anti-PCP treatment. Type Ne presented an association with negative response to anti-PCP treatment (P<0.001) and with death before 120 days after PCP diagnosis (P=0.025). Type Eb was significantly more common in children than in adults (P=0.001). Our data suggest an association of specific ITS genotypes with treatment failure, bad clinical outcome and childhood.

Persistent cognitive activity is an important factor in disturbing sleep-onset both during bedtime and when attempting to get back to sleep after nocturnal awakenings. One of the most specific self-report measures designed to assess this feature is the Glasgow Content of Thoughts Inventory (GCTI). In this study, we investigated the preliminary psychometric properties of GCTI in a large sample of higher education European Portuguese students (N = 2995). Our results suggest that there is evidence of good internal consistency (α = 0.93) and validity indicators. Moreover, we found an interpretable factorial structure comprising 5 correlated factors that needs to be confirmed in future studies. The European Portuguese version of the GCTI appears to be a reliable and valid instrument for measurement of sleep-onset disturbing cognitions.

In this article, we introduce ESCOLEX, the first European Portuguese children's lexical database with grade-level-adjusted word frequency statistics. Computed from a 3.2-million-word corpus, ESCOLEX provides 48,381 word forms extracted from 171 elementary and middle school textbooks for 6- to 11-year-old children attending the first six grades in the Portuguese educational system. Like other children's grade-level databases (e.g., Carroll, Davies, & Richman, 1971; Corral, Ferrero, & Goikoetxea, Behavior Research Methods, 41, 1009-1017, 2009; Lété, Sprenger-Charolles, & Colé, Behavior Research Methods, Instruments, & Computers, 36, 156-166, 2004; Zeno, Ivens, Millard, Duvvuri, 1995), ESCOLEX provides four frequency indices for each grade: overall word frequency (F), index of dispersion across the selected textbooks (D), estimated frequency per million words (U), and standard frequency index (SFI). It also provides a new measure, contextual diversity (CD). In addition, the number of letters in the word and its part(s) of speech, number of syllables, syllable structure, and adult frequencies taken from P-PAL (a European Portuguese corpus-based lexical database; Soares, Comesaña, Iriarte, Almeida, Simões, Costa, …, Machado, 2010; Soares, Iriarte, Almeida, Simões, Costa, França, …, Comesaña, in press) are provided. ESCOLEX will be a useful tool both for researchers interested in language processing and development and for professionals in need of verbal materials adjusted to children's developmental stages.

Depression and anxiety have been associated with a range of symptoms that often overlap. Depression, Anxiety and Stress Scale-21 (DASS-21) is a single instrument to assess symptoms of depression, anxiety and stress. This study aimed to adapt and validate the DASS-21 for use in the Brazilian Portuguese language. The DASS-21 has been adapted following the translation-back translation methodology from English to Portuguese. 242 subjects completed the following assessments: the DASS-21, the Beck Depression Index (BDI), Beck Anxiety Index (BAI) and the Inventory of Stress Symptoms of Lipp (ISSL). The Kaiser-Meyer-Olkin (KMO) result was .949, indicating that the adequacy of the model was high. Cronbach's alpha was .92 for the depression, .90 for the stress, and .86 for the anxiety, indicating a good internal consistency for each subscale. The correlations between DASS scale and BDI scale, BAI scale and ISSL inventory were strong. The factorial analysis and distribution of factors among the subscales indicated that the structure of three distinct factors is adequate. Older subjects over 65 years of age were not largely represented in this sample. A study specific to this elderly population should be conducted. Another limitation of the study was education level. The impact of low education in its applicability should be considered. The findings support the validity of the Brazilian Portuguese version of the DASS-21 and add to the evidence of the DASS-21 quality and ability to assess emotional states separately, eliminating the use of different instruments to assess these states. © 2013 Published by Elsevier B.V.

The Fibromyalgia Impact Questionnaire (FIQ) was specifically developed to assess disease severity and functional ability in fibromyalgia patients. In 2009, a revised version of the FIQ was published, the FIQR; this version achieved a better balance among different domains (function, overall impact, symptoms). Here, we present the validity and reliability of the Brazilian version of the Revised Fibromyalgia Impact Questionnaire (FIQR). Female fibromyalgia patients (n = 106) completed an online survey consisting of the Short Form 36 (SF-36) questionnaire, the original FIQ, and the Brazilian Portuguese FIQR, which was translated by a standard method. Validity was established with correlational analyses between the FIQR, FIQ, and SF-36 items. Three domains were established for the FIQR (function, overall impact, symptoms), and their contribution for the SF-36 subscales was also scrutinized. The Brazilian FIQR validation process showed that the questions performed in a very similar way to the original English FIQR. The new questions in the FIQR symptoms domain (memory, balance, tenderness, and environmental sensitivity) revealed a significant impact in fibromyalgia (FM) patients. The Brazilian Portuguese FIQR demonstrated excellent reliability, with a Cronbach's alpha of 0.96. There was a gain on weight of the function domain and a decrease of the symptom domain, leading to a better balance among domains. The FIQR predicted a great number of SF-36 subscales, showing good convergent validity. The Brazilian Portuguese version of the FIQR was validated and found to be a reliable, easy-to-use, and score FM-specific questionnaire that should prove useful in routine clinical practice and FM-related research.

Normative data were established for newly developed speech materials for nasalance assessment in Brazilian Portuguese. Nasalance scores of preexisting passages (oral ZOO-BR, low-pressure oral ZOO-BR2 and NASAL-BR), new nasalance passages (oral Dudu no zoológico, oral Dudu no bosque, oral-nasal O cãozinho Totó and nasal O nenê) and Brasilcleft articulation screening sentences were collected from 245 speakers of Brazilian Portuguese, including 121 males and 124 females, divided into 4 groups: children (5-9 years), adolescents (10-19 years), young adults (20-24 years) and adults (25-35 years). Across all nasalance passages, adult females scored on average 2 percentage points higher than males. Children scored 2-4 percentage points lower than older groups for the preexisting nasalance passages ZOO-BR and ZOO-BR2. Nasalance scores for the new nasalance passages were not significantly different from the preexisting passages. Scores for high-pressure sentences did not differ significantly from the oral nasalance passage Dudu no bosque. The nasalance scores for the new nasalance passages were equivalent to the preexisting materials. The new shortened and simplified nasalance passages will be useful for assessing young children. Normative scores for the Brasilcleft high-pressure sentences were equivalent to the new oral passage Dudu no bosque. © 2016 S. Karger AG, Basel.

This study examined the reliability and validity of the Brazilian Portuguese version of the Treatment Satisfaction Questionnaire for Medication (version 1.4) among patients with hypertension. Understanding the patient experience with treatment satisfaction will contribute to improved medication adherence and control of hypertension. Hypertension is a serious problem in Brazil that is associated with chronic illness controlled, in part, by consistent adherence to medications. Patient satisfaction with medication treatment is associated with adherence to medication. The Treatment Satisfaction Questionnaire for Medication (version 1.4) is a promising instrument for measuring medication; however, to date there has been no report of the reliability and validity of the instrument with Portuguese-speaking adults with hypertension in Brazil. Cross-sectional descriptive exploratory study. A convenience sample of 300 patients with hypertension in an outpatient setting in the southeast region of São Paulo state in Brazil completed the Treatment Satisfaction Questionnaire for Medication (version 1.4). The instrument, comprised of four subscales, was evaluated for reliability using correlation analyses and internal consistency. Confirmatory factor analysis was used to determine factorial validity. Correlational analyses, internal consistency (Cronbach's alpha) and hierarchical confirmatory factor analysis demonstrate adequate support for the four-factor dimensionality, reliability and factorial validity of the Treatment Satisfaction Questionnaire for Medication (version 1.4). This study provides modest evidence for internal consistency and factorial validity of the Treatment Satisfaction Questionnaire for Medication (version 1.4) in Portuguese-speaking adult Brazilians with hypertension. Future testing should focus on extending reliability testing, discriminant validity and potential translation and literacy issues in this population. Within known limitations, clinicians will

No one aims at applying generic measures as substitutes for other more traditional clinical procedures. The whole history of the evolution of these types of measures has been based on comparisons with clinical measures, always seen by researchers as ways to validate health outcome measures and as a process to be recognized by clinicians as a way to detect changes in time not always detected by the usual measures. The measurement instrument presented in this paper is the Portuguese version of the MOS SF-36, originally a result of the Medical Outcomes Study, a study carried out by Rand Corporation researchers in the 80's. One of the objectives of these researchers was precisely to develop instruments to be used in continuous monitoring of outcomes. This paper describes the first time MOS SF-36 was culturally adapted to Portuguese, validated and implemented. The first part mentions some of the foundations and developments of the original instrument as well as some results obtained from some specific applications. The second part introduces operational definitions for each of the eight scales and describes the SF-36 measurement model as well as the factor structure with two dimensions. Next, we present the design used by us to transform the data from the time they are collected from the respondents to the time they are ready to be further used. Finally, the methodology used to culturally adapt the MOS SF-36 and create a Portuguese version which is culturally equivalent are presented.

Propolis is a chemically complex resinous substance collected by honeybees (Apis mellifera) from tree buds, comprising plant exudates, secreted substances from bee metabolism, pollen and waxes. Its chemical composition depends strongly on the plant sources available around the beehive, which have a direct impact in the quality and bioactivity of the propolis. Being as Portugal is a country of botanical diversity, the phenolic characterisation of propolis from the different regions is a priority. Extensive characterisation of the phenolic composition of Portuguese propolis from different continental regions and islands. Forty propolis ethanolic extracts were analysed extensively by liquid chromatography with diode-array detection coupled to electrospray ionisation tandem mass spectrometry (LC-DAD-ESI-MS(n) ). Seventy-six polyphenols were detected in the samples and two groups of propolis were established: the common temperate propolis, which contained the typical poplar phenolic compounds such as flavonoids and their methylated/esterified forms, phenylpropanoid acids and their esters, and an uncommon propolis type with an unusual composition in quercetin and kaempferol glycosides - some of them never described in propolis. The method allowed the establishment of the phenolic profile of Portuguese propolis from different geographical locations, and the possibility to use some phenolic compounds, such as kaempferol-dimethylether, as geographical markers. Data suggest that other botanical species in addition to poplar trees can be important sources of resins for Portuguese propolis. Copyright © 2012 John Wiley & Sons, Ltd.

In 2009-2010 a Portuguese consortium was created to implement the methodologies proposed by the Dose Datamed II (DDM2) project, aiming to collect data from diagnostic X-ray and nuclear medicine (NM) procedures, in order to determine the most frequently prescribed exams and the associated ionizing radiation doses for the Portuguese population. The current study is the continuation of this work, although it focuses only on NM exams for the years 2011 and 2012. The annual frequency of each of the 28 selected NM exams and the average administered activity per procedure was obtained by means of a nationwide survey sent to the 35 NM centres in Portugal. The results show a reduction of the number of cardiac exams performed in the last two years compared with 2010, leading to a reduction of the annual average effective dose of Portuguese population due to NM exams from 0.08 mSv ± 0.017 mSv/caput to 0.059 ± 0.011 mSv/caput in 2011 and 0.054 ± 0.011 mSv/caput in 2012. Portuguese total annual average collective effective dose due to medical procedures was estimated to be 625.6 ± 110.9 manSv in 2011 and 565.1 ± 117.3 manSv in 2012, a reduction in comparison with 2010 (840.3 ± 183.8 manSv). The most frequent exams and the ones that contributed the most for total population dose were the cardiac and bone exams, although a decrease observed in 2011 and in 2012 was verified. The authors intend to perform this study periodically to identify trends in the annual Portuguese average effective dose and to help to raise awareness about the potential dose optimization.

The aim of this paper was to assess the prevalence of suicide ideation and attempts in Portuguese psychiatry trainees (adult and child and adolescence), and compare the data with the general population and other European countries. A structured and anonymous questionnaire was sent by email to 159 portuguese trainees of adult psychiatry and child and adolescence psychiatry with questions about personal history of suicidal ideation and suicide attempts, as well as family history of suicide attempts and completed suicides. This is part of the BoSS Study (Burnout Syndrome Study) performed in 21 countries worldwide. Data was analysed in SPSS v.19. From the inquired population, 62 trainees (40,3%) partially responded, and 46 (29%) were complete responders - these entered the final analysis. There was a ratio of 2:1 (female:male) and a mean age of 29 years. The suicidal ideation was present in passive form in 44% and in active form in 33%; also, 4.3% of respondents had previous suicide attempts. In first degree relatives, 22% had attempted suicide and 13% completed suicide. The results are worriying and may be associated with some factors to which this population is exposed. It is necessary further research to better understand this phenomenon, its causes and potential modifiers.

optimism is an important variable that has consistently been shown to affect adjustment to quality of life in chronic diseases. This study aims to clarify if dispositional optimism exerts a moderating or a mediating influence on the personality traits-quality of life association, in Portuguese chronic patients. multiple regression models were used to test the moderation and mediation effects of dispositional optimism in quality of life. A sample of 729 patients was recruited in Portugal's main hospitals and completed self-reported questionnaires assessing socio-demographic and clinical variables, personality, dispositional optimism, quality of life (QoL) and subjective well-being (SWB). the results of the regression models showed that dispositional optimism did not moderate the relationships between personality traits and quality of life. After controlling for gender, age, education level and severity of disease perception, the effects of personality traits on QoL and in SWB were mediated by dispositional optimism (partially and completely), except for the links between neuroticism/openness to experience and physical health. dispositional optimism is more likely to play a mediating, rather than a moderating role in personality traits-quality of life pathway in Portuguese chronic patients, suggesting that "the expectation that good things will happen" contributes to a better quality of life and subjective well-being.

The aim of the present study was to evaluate the association between parenting styles and own fruit and vegetable consumption among Portuguese mothers of school children. A cross-sectional study was performed in Portugal as part of the Pro Children cross-sectional European survey. Portuguese mothers (n 1601) of 11-13-year-old school children were included in the present study. A self-administered questionnaire was developed to assess fruit and vegetable consumption as well as the parenting styles. Fruit and vegetable consumption was assessed by a validated FFQ. Parenting styles based on two dimensions - strictness and involvement - were classified into authoritative, authoritarian, indulgent and neglectful. The higher mean intakes of fruit, vegetables and total fruit and vegetables were observed for mothers classified as indulgent, whereas the lower mean intakes were observed for mothers classified as neglectful. Differences in intake among parenting styles were significant for fruit, vegetables and total fruit and vegetables. When partial correlations were calculated between the two dimensions, strictness and involvement (controlled one for the other), and intakes, only involvement was positively associated with fruit, vegetables and total fruit and vegetable intake. Findings from the present study show that fruit and vegetable consumption of Portuguese mothers of school children seems to be related to their own parenting styles, especially with the dimension involvement. Future interventions to promote fruit and vegetable intake should take into account these variables.

To gather epidemiologic information on the spread of human immunodeficiency virus (HIV)-2 in Portugal, sera were collected in 1985 from 156 healthy adults currently living in Portugal but natives of Guinea Bissau, Cape Verde Islands, Saint Tome/Prince, Angola, and Mozambique and from 321 native Portuguese men and women who had close contact with local African populations. As a control, sera were collected from 102 health Portuguese with no previous contact with Africa or African natives. The enzyme-linked immunosorbent assay (ELISA) developed by Diagnostic Pasteur was used to screen for antibodies to HIV. No positive reactions were recorded in the control population. In contracts, 9 (6%) of the African natives and 7 (2%) of the contacts of Africans were HIV-positive, 6 of the positive sera were from women and 10 were from men. Significantly, 1 of the HIV-2-positive serum samples was from a native of Mozambique and 3 were from natives of Angola. This suggests that HIV-2 infection may have spread to other former Portuguese colonies, and foreign army soldiers who were at 1 time residents of Mozambique or Angola should be considered a risk group capable of spreading HIV-2 infection to other countries.

The Portuguese population is reported to have among the highest levels of mean blood pressure. The aim of the present study is to conduct a structured literature review describing the scope (quantity, focus and nature) of published epidemiological research on the prevalence and incidence of hypertension in the Portuguese population. The scoping review was conducted during June 2013, using two information sources, B-on and PubMed, to search for published studies on the prevalence and incidence of hypertension with data collected between 2005-2013 and 1995-2013, respectively. We identified 527 publications: 14 on the prevalence and two on the incidence of hypertension. The results show more studies on populations in the North region of Portugal; an apparent lack of published studies specifically targeting the Alentejo and Algarve populations; long delays between data collection and publication of results (up to nine years); considerable variability in measurement methods; and infrequent data stratification by gender and age. Differences in blood pressure measurement methods, not specified in most studies, the infrequency of stratification of results by gender and age, and the geographic asymmetry in coverage of the Portuguese population, hinder monitoring of the incidence and prevalence of hypertension in Portugal.

Aflatoxin B1 (AFB1) is considered by different International Agencies as a genotoxic and potent hepatocarcinogen. However, despite the fact that the fungi producing this compound are detected in some work environments, AFB1 is rarely monitored in occupational settings. The aim of the present investigation was to assess exposure to AFB1 of workers from one Portuguese waste company located in the outskirt of Lisbon. Occupational exposure assessment to AFB1 was done with a biomarker of internal dose that measures AFB1 in the serum by enzyme-linked immunosorbent assay. Forty-one workers from the waste company were enrolled in this study (26 from sorting; 9 from composting; 6 from incineration). A control group (n = 30) was also considered in order to know the AFB1 background levels for the Portuguese population. All the workers showed detectable levels of AFB1 with values ranging from 2.5ng ml(-1) to 25.9ng ml(-1) with a median value of 9.9±5.4ng ml(-1). All of the controls showed values below the method's detection limit. Results obtained showed much higher (8-fold higher) values when compared with other Portuguese settings already studied, such as poultry and swine production. Besides this mycotoxin, other mycotoxins are probably present in this occupational setting and this aspect should be taken into consideration for the risk assessment process due to possible synergistic reactions. The data obtained suggests that exposure to AFB1 occurs in a waste management setting and claims attention for the need of appliance of preventive and protective safety measures. © The Author 2014.

Does health promote economic growth? Portuguese case study: from dictatorship to full democracy.

2014-07-01

This paper revisits the debate on health and economic growth (Deaton in J Econ Lit 51:113-158, 2003) focusing on the Portuguese case by testing the relationship between growth and health. We test Portuguese insights, using time series data from 1960 to 2005, taking into account different variables (life expectancy, labour, capital, infant mortality) and considering the years that included major events on the political scene, such as the dictatorship and a closed economy (1960-1974), a revolution (1974) and full democracy and an open economy (1975-2005), factors that influence major economic, cultural, social and politic indicators. Therefore the analysis is carried out adopting Lucas' (J Monet Econ 22(1):3-42, 1988) endogenous growth model that considers human capital as one factor of production, it adopts a VAR (vector autoregressive) model to test the causality between growth and health. Estimates based on the VAR seem to confirm that economic growth influences the health process, but health does not promote growth, during the period under study.

Patients' knowledge about oral anticoagulant therapy may favor the achievement of therapeutic results and the prevention of adverse pharmacotherapy-related events. Brazil lacks validated instruments for assessing the patient's knowledge about treatment with warfarin. This study aimed to perform the cross-cultural adaptation of the Oral Anticoagulation Knowledge (OAK) Test instrument from English into Portuguese. This is a methodological study developed in an anticoagulation clinic of a public university hospital. The study included initial translation, synthesis of translations, back-translation, review by the experts committee and pre-testing with 30 individuals. We obtained semantic equivalence through the analysis of the referential and general meaning of each item. The conceptual equivalence of the items sought to demonstrate the relevance and acceptability of the instrument. The process of cross-cultural adaptation produced the final version of the OAK Test in Brazilian Portuguese entitled "Teste de Conhecimento sobre Anticoagulação Oral". There was a suitable semantic and conceptual equivalence between the adapted version and the original version, as well as an excellent acceptability of this instrument.

Portuguese American gay men in southeastern Massachusetts: cultural scripts and risk for HIV.

Jordan, Kathleen M; Johnson, Asal M; Johnson, James A; Holman, Jeremy

2016-10-01

In this study, we examined the lived experiences of an understudied subgroup, Portuguese American gay men, within the context of sexual script theory. We employed a phenomenological study design with eight men to provide a more in-depth analysis of their sociocultural sexual behaviours. Recruitment was conducted through word of mouth and a snowball approach beginning with two well-known HIV education and prevention outreach centres in southeastern Massachusetts. In this study, the sexual scripts of the participants were conceptualised within the three domains of cultural, interpersonal and intrapsychic scripts. Our findings suggest the three scripts are constantly interacting and informing one another. This ongoing negotiation influences the way our participants position their sexuality within the broader context of their everyday life within the US Portuguese community. Participants script their sexuality while they navigate multiple but separate entities within their culture, their religion and their families. Learning from these experiences could have important implications for the development of HIV prevention programmes for specific subgroups of men who have sex with men.

Most studies characterizing errors in the speech of patients with apraxia involve English language. To analyze the types and frequency of errors produced by patients with apraxia of speech whose mother tongue was Brazilian Portuguese. 20 adults with apraxia of speech caused by stroke were assessed. The types of error committed by patients were analyzed both quantitatively and qualitatively, and frequencies compared. We observed the presence of substitution, omission, trial-and-error, repetition, self-correction, anticipation, addition, reiteration and metathesis, in descending order of frequency, respectively. Omission type errors were one of the most commonly occurring whereas addition errors were infrequent. These findings differed to those reported in English speaking patients, probably owing to differences in the methodologies used for classifying error types; the inclusion of speakers with apraxia secondary to aphasia; and the difference in the structure of Portuguese language to English in terms of syllable onset complexity and effect on motor control. The frequency of omission and addition errors observed differed to the frequency reported for speakers of English.

The isolation of bioactive compounds from medicinal plants, based on traditional use or ethnomedical data, is a highly promising potential approach for identifying new and effective antimalarial drug candidates. The purpose of this review was to create a compilation of the phytochemical studies on medicinal plants used to treat malaria in traditional medicine from the Community of Portuguese-Speaking Countries (CPSC): Angola, Brazil, Cape Verde, Guinea-Bissau, Mozambique and São Tomé and Príncipe. In addition, this review aimed to show that there are several medicinal plants popularly used in these countries for which few scientific studies are available. The primary approach compared the antimalarial activity of native species used in each country with its extracts, fractions and isolated substances. In this context, data shown here could be a tool to help researchers from these regions establish a scientific and technical network on the subject for the CPSC where malaria is a public health problem.

Although livestock-associated ST398 methicillin-resistant Staphylococcus aureus (MRSA) has been widely reported in different geographic regions, MRSA carriage studies among healthy pigs in Portugal are very limited. In total, 101 swine nasal samples from two Portuguese farms were screened for MRSA. In addition five swine workers (including one veterinary and one engineer) and four household members were nasally screened. The isolates were characterized by spa typing, SCCmec typing and MLST. All isolates were tested for antimicrobial susceptibility, presence of mecA and mecC genes, and virulence determinants. MRSA prevalence in swine was 99% (100/101), 80% (4/5) in swine workers and 25% (1/4) in household members. All isolates belonged to ST398 distributed over two spa types-t011 (57%) and t108 (42%). SCCmec type V was present in most of the isolates (n = 95; 82%) while 21 isolates amplified the mecA gene only and were classified as nontypeable. The majority of the isolates were resistant to tetracycline (100%), clindamycin (97%), erythromycin (96%), chloramphenicol (84%) and gentamycin (69%). Notably, 12% showed resistance to quinupristin-dalfopristin (MICs 3-8 μg/mL). Beta-hemolysin (81%) and gamma-hemolysin (74%) were the unique virulence determinants detected. None of the isolates harboured PVL or mecC gene. This study showed a massive occurrence of ST398-MRSA in two independent swine farms, highlighting its establishment among healthy pigs in Portugal.

This study investigated the yeast community present in the traditional Portuguese cheese, Serpa, by culture-dependent and -independent methods. Sixteen batches of Serpa cheeses from various regional industries registered with the Protected Designation of Origin (PDO) versus non-PDO registered, during spring and winter, were used. Irrespective of the producer, the yeast counts were around 5log CFU/g in winter and, overall, were lower in spring. The yeast species identified at the end of ripening (30days), using PCR-RFLP analysis and sequencing of the 26S rRNA, mainly corresponded to Debaryomyces hansenii and Kluyveromyces marxianus, with Candida spp. and Pichia spp. present to a lesser extent. The culture-independent results, obtained using high-throughput sequencing analysis, confirmed the prevalence of Debaryomyces spp. and Kluyveromyces spp. but, also, that Galactomyces spp. was relevant for three of the five producers, which indicates its importance during the early stages of the cheese ripening process, considering it was not found among the dominant viable yeast species. In addition, differences between the identified yeast isolated from cheeses obtained from PDO and non-PDO registered industries, showed that the lack of regulation of the cheese-making practice, may unfavourably influence the final yeast microbiota. The new knowledge provided by this study of the yeast diversity in Serpa cheese, could be used to modify the cheese ripening conditions, to favour desirable yeast species. Additionally, the prevalent yeast isolates identified, Debaryomyces hansenii and Kluyveromyces spp., may have an important role during cheese ripening and in the final sensorial characteristics. Thus, the study of their technological and functional properties could be relevant, in the development of an autochthonous starter culture, to ensure final quality and safety of the cheese.

Childhood obesity is a public health concern in Portugal. Socio-demographic and behavioral factors are highly associated with obesity but are not clearly understood. This article aims to update the prevalence of overweight and obesity in Portuguese children and to explore the influence and risks of socio-demographic factors and behavioral factors. A cross-sectional study of Portuguese children aged 3-10 years from all 18 mainland districts took place between March 2009 and January 2010. The sample was composed by 17,136 children, 3-10 years of age (8,455 boys; 8,681 girls). Height, weight, and other anthropometric measurements were obtained by trained technicians. Body mass index (BMI) was calculated along with other anthropometric variables. Data analyses took place between April and September 2012. The overweight/obesity classification was established by age-and sex-specific BMI cut-off points as defined by the International obesity task force (IOTF). Parents completed questionnaires about socio-demographic and behavioral characteristics of the family. Almost 28% of the Portuguese children were overweight or obese (19.7% overweight; 8.2% obese). Prevalence was greater in girls than in boys. Logistic regression models found that the odds of childhood obesity were significantly affected by biological, socio-demographic, and behavioral factors. The protective factors against childhood overweight/obesity in this sample of Portuguese children are: (i) being male; (ii) having been breastfeed; (iii) having been born from mothers who did not smoke during pregnancy; (iv) engaging in little sedentary behaviors (TV, PC, and playing electronic games); (iv) performing at least 1 h of moderate physical activity every day; and (v) having parents with higher educational levels who also have their BMI within the healthy ranges.

Spondylotic cervical myelopathy (SCM) is a common cause of spinal-related disability in the elderly. The assessment of this disability is a challenging task and depends on the subjective evaluation of the investigator. As a widespread used scale, the modified scale of the Japanese Association of Orthopedics (mJOA) should be translated and culturally adapted in the Brazilian Portuguese language (mJOA-Br) to provide its clinical and research use. This study aims to do translation, transcultural adaptation and validation of the mJOA, into Brazilian Portuguese language. Following the transcultural adaptation model described by Guillemin et al., the scale as translated into Brazilian Portuguese and back-translated to English. Afterwards, questionnaires were applied in consecutive patients with SCM and compared to a control group (without SCM). The final scale was compared to the Brazilian version of Neck Disability Index for validation. Sixty patients were submitted to the translated version of mJOA. There was strong correlation between mJOA-Br scores and NDI scores to evaluate SCM symptoms (R=-0.75). mJOA-Br was considered a valid and reliable tool to evaluate SCM patients.

This study analyses the psychometric proprieties of a Portuguese version of the social competence scale from the School Social Behavior Scales (SSBS-2, Merrell, 2002). It is a rating instrument of children and adolescents behavior, to be used by teachers and other school personnel. This scale includes 3 subscales: self-management/compliance, peer relations and academic behavior. In our first sample, 175 teachers rated 344 students from grade 1 through 12. On the second sample 13 teachers rated 251 3rd and 4th grades students. The results from the Portuguese adaptation support the multidimensional structure of the social competence scale from the SSBS-2, although an alternative model demonstrated a better fit to the data than the model originally proposed by the author. The scale showed good internal consistency and good intercorrelations between subscales, as well as between subscales and the total scale. The final model was well replicated in the second sample. These results encourage us to pursue the SSBS-2 Portuguese adaptation, in order to provide a useful and validated instrument for the assessment of social competence and for educational interventions.

Rescue workers have a stressful and risky occupation where being engaged is crucial to face physical and emotional risks in order to help other persons. This study aims to estimate work engagement levels of rescue workers (namely comparing nurses, firefighters, and police officers) and to assess the validity evidence related to the internal structure of the Portuguese versions of the UWES-17 and UWES-9, namely, dimensionality, measurement invariance between occupational groups, and reliability of the scores. To evaluate the dimensionality, we compared the fit of the three-factor model with the fit of a second-order model. A Portuguese version of the instrument was applied to a convenience sample of 3,887 rescue workers (50% nurses, 39% firefighters, and 11% police officers). Work engagement levels were moderate to high, with firefighters being the highest and nurses being the lowest engaged. Psychometric properties were evaluated in the three-factor original structure revealing acceptable fit to the data in the UWES-17, although the UWES-9 had better psychometric properties. Given the observed statistically significant correlations between the three original factors, we proposed a 2nd hierarchal structure that we named work engagement. The UWES-9 first-order model obtained full uniqueness measurement invariance, and the second-order model obtained partial (metric) second-order invariance. PMID:29403403

Quality of life is an important measure for health-outcome evaluation. Although otitis media is one of the most common childhood diseases, its impact on Portuguese children's quality of life is unknown. The aim of this study is to determine the quality of life of Portuguese children with chronic otitis media with effusion and/or recurrent acute otitis media and the short-term impact of transtympanic ventilation tubes, using the Portuguese version of the OM-6 questionnaire, a valid, reliable and sensitive instrument to evaluate the health-related quality of life in children with otitis media. This study was conducted in a tertiary referral center, to where children are referred from primary care and hospital pediatric consultations. The Portuguese version of the OM-6 questionnaire was applied to children with chronic otitis media with effusion and/or recurrent acute otitis media. The instrument was re-administered at two months postoperatively to a group of children who underwent tympanostomy tube placement, to evaluate the change in quality of life with the surgical procedure. The study involved a sample of 169 children, aged between 6 months and 12 years (mean: 4.20 ± 2.05 years). The average score in the survey was 3.3 ± 1.47, of a maximum of 7 (worst quality of life). The domains 'caregiver concerns', 'hearing loss' and 'physical suffering' had the highest scores. The domain 'hearing loss' was correlated with the domain 'speech impairment' (rs = 0.41; p < 0.001) and the domain 'physical suffering' correlated with the domain 'activity limitation' (rs = 0.47; p < 0.001). There was a correlation between the score on 'hearing loss' and the presence of conduction hearing loss (χ2 (6) = 24.662; p = 0.022). Children with chronic otitis media with effusion had lower scores on the domain 'physical suffering', while children with recurrent acute otitis media had lower scores in the domain 'hearing loss' and higher scores in the domain 'emotional distress'.

Objective To translate, culturally adapt and validate the "Knee Society Score"(KSS) for the Portuguese language and determine its measurement properties, reproducibility and validity. Methods We analyzed 70 patients of both sexes, aged between 55 and 85 years, in a cross-sectional clinical trial, with diagnosis of primary osteoarthritis ,undergoing total knee arthroplasty surgery. We assessed the patients with the English version of the KSS questionnaire and after 30 minutes with the Portuguese version of the KSS questionnaire, done by a different evaluator. All the patients were assessed preoperatively, and again at three, and six months postoperatively. Results There was no statistical difference, using Cronbach's alpha index and the Bland-Altman graphical analysis, for the knees core during the preoperative period (p =1), and at three months (p =0.991) and six months postoperatively (p =0.985). There was no statistical difference for knee function score for all three periods (p =1.0). Conclusion The Brazilian version of the Knee Society Score is easy to apply, as well providing as a valid and reliable instrument for measuring the knee score and function of Brazilian patients undergoing TKA. Level of Evidence: Level I - Diagnostic Studies- Investigating a Diagnostic Test- Testing of previously developed diagnostic criteria on consecutive patients (with universally applied 'gold' reference standard).

Systemic sclerosis (SSc) is a multisystem disease, autoimmune disorder characterized by a fibroblastic disfunction, with significant impact on quality of life (QoL), measured by instruments or questionnaires that usually were formulated in other languages and in different cultural contexts. Translate into Brazilian Portuguese, cross cultural adaptation and assess the reliability and validity of the Systemic Sclerosis Questionnaire (SySQ). Translation and adaptation: into Portuguese and cross-cultural adaptation was performed in accordance with studies on questionnaire translation methodology into other languages. Reliability: it was analyzed using three interviews with different interviewers, two on the same day (interobserver) and the third within 14 days of the first assessment (intraobserver).Validity was assessed by correlating clinical and quality of life parameters with the domain scores of Sysc. a descriptive analysis of the study sample. Reproducibility was assessed using an intraclass correlation coefficient (ICC). Internal consistency was assessed using Cronbach's alpha coefficient. To assess validity we used Spearman correlation coefficient. Five percent was the level of significance adopted for all statistical tests. In the evaluation of the questionnaires, the results were similar to the original questionnaire, the internal consistency ranging between 0.73 and 0.93 for each item. The interobserver reproducibility was very good for all domains (α = 0.786 to 0.983) and intraobserver agreement was considered very good for general symptoms domain (ICC = 0.916), good for musculoskeletal symptoms domain (ICC = 0.897) and cardiopulmonary domain (ICC = 0.842) and reasonable for gastrointestinal symptoms domain (ICC = 0.686). The Brazilian Portuguese version of SySQ proved to be reproducible and valid for our population, using a recognized methodology for translation and cultural adaptation of questionnaires, as well as to assess the reproducibility and

2015-01-01

Background Physicians’ ability to make cost-effective decisions has been shown to be affected by their knowledge of health care costs. This study assessed whether Portuguese family physicians are aware of the costs of the most frequently prescribed diagnostic and laboratory tests. Methods A cross-sectional study was conducted in a representative sample of Portuguese family physicians, using computer-assisted telephone interviews for data collection. A Likert scale was used to assess physician’s level of agreement with four statements about health care costs. Family physicians were also asked to estimate the costs of diagnostic and laboratory tests. Each physician’s cost estimate was compared with the true cost and the absolute error was calculated. Results One-quarter (24%; 95% confidence interval: 23%–25%) of all cost estimates were accurate to within 25% of the true cost, with 55% (95% IC: 53–56) overestimating and 21% (95% IC: 20–22) underestimating the true actual cost. The majority (76%) of family physicians thought they did not have or were uncertain as to whether they had adequate knowledge of diagnostic and laboratory test costs, and only 7% reported receiving adequate education. The majority of the family physicians (82%) said that they had adequate access to information about the diagnostic and laboratory test costs. Thirty-three percent thought that costs did not influence their decision to order tests, while 27% were uncertain. Conclusions Portuguese family physicians have limited awareness of diagnostic and laboratory test costs, and our results demonstrate a need for improved education in this area. Further research should focus on identifying whether interventions in cost knowledge actually change ordering behavior, in identifying optimal methods to disseminate cost information, and on improving the cost-effectiveness of care.

To translate into Brazilian Portuguese and cross-culturally adapt the Cardiff Wound Impact Schedule, a specific measure of health-related quality of life (HRQoL) for patients with chronic wounds. Chronic wounds have a relevant impact on the HRQoL of patients. However, there are few instruments cross-culturally adapted and validated in Brazil to assess HRQoL in patients with wounds. A descriptive cross-sectional study was conducted following six steps: (1) translation of the original instrument into Brazilian-Portuguese by two independent translators; (2) construction of a consensus version based on both translations; (3) two independent back-translations into English of the consensus version; (4) review by an expert committee and construction of the pre-final version; (5) testing of the pre-final version on patients with chronic wounds; and (6) construction of the final version. The psychometric properties of the instrument were tested on 30 patients with chronic wounds of the lower limb; 76.7% were men, 70.0% had traumatic wounds, and 43.3% had the wound for more than 1 year. Participants were recruited from an outpatient wound care clinic in São Paulo, Brazil. The final version approved by the expert committee was well understood by all patients who participate in the study and had satisfactory face validity, content validity, and internal consistency, with Cronbach's alpha coefficients ranging from 0.681 to 0.920. The cross-culturally adapted Brazilian-Portuguese version of the instrument showed satisfactory face and content validity, good internal consistency, and was named Cardiff Wound Impact Schedule-Federal University of São Paulo School of Medicine or CWIS-UNIFESP/EPM.

Objective : To translate The Manchester Respiratory Activities of Daily Living (MRADL) questionnaire into Portuguese and to create a version of the MRADL that is cross-culturally adapted for use in Brazil. Methods : The English-language version of the MRADL was translated into Portuguese by two health care researchers who were fluent in English. A consensus version was obtained by other two researchers and a pulmonologist. That version was back-translated into English by another translator who was a native speaker of English and fluent in Portuguese. The cognitive debriefing process consisted in having 10 COPD patients complete the translated questionnaire in order to test its understandability, clarity, and acceptability in the target population. On the basis of the results, the final Portuguese-language version of the MRADL was produced and approved by the committee and one of the authors of the original questionnaire. Results : The author of the MRADL questioned only a few items in the translated version, and some changes were made to the mobility and personal hygiene domains. Cultural differences regarding the domestic activities domain were found, in particular regarding the item "Do you have the ability to do a full clothes wash and hang them out to dry?", due to socioeconomic and climatic issues. The item "Do you take care of your garden?" was questioned by the participants who lived in apartments, being modified to "Do you take care of your garden or plants in your apartment?" Conclusions : The final Portuguese-language version of the MRADL adapted for use in Brazil was found to be easy to understand and easily applied. PMID:26982036

To share Portugal's experience with school-based sexuality education, and to describe its implementation at a local level, following an ecological model and using a mixed methodology approach. The study also examines the impact of the latest policies put into effect, identifying potential weaknesses and strengths affecting the effectiveness of sexuality education enforcement. A representative sample of 296 schools in Portugal was analysed. Teachers representing the school completed a questionnaire and were asked to share any kind of official document from their sexuality education project (such as curriculum content). A subsample of these documents was analysed by two coders. Quantitative analysis was carried out using descriptive statistics. The majority of Portuguese schools delivered sexuality education, in line with Portuguese technical guidelines and international recommendations. There were common procedures in planning, implementation and evaluation of sexuality education. Some strengths and weaknesses were identified. Results highlighted the impact of the various systems on the planning, enforcement and evaluation of sexuality education in school. The latest policies introduced valuable changes in school-based sexuality education. A way of assessing effectiveness of sexuality education is still needed.

Purpose To validate the Quality of Erection Questionnaire (QEQ) considering Brazilian social-cultural aspects. Materials and Methods To determine equivalence between the Portuguese and the English QEQ versions, the Portuguese version was back-translated by two professors who are native English speakers. After language equivalence had been determined, urologists considered the QEQ Portuguese version suitable. Men with self-reported erectile dysfunction (ED) and infertile men who had a stable sexual relationship for at least 6 months were invited to answer the QEQ, the International Index of Erectile Function (IIEF) and the RAND 36-Item Health Survey (RAND-36). The questionnaires were presented together and answered without help in a private room. Internal consistency (Cronbach’s α), test-retest reliability (Spearman), convergent validity (Spearman correlation) coefficients and known-groups validity (the ability of the QEQ Portuguese version to differentiate erectile dysfunction severity groups) were assessed. Results We recruited 197 men (167 ED patients and 30 non-ED patients), mean age of 53.3 and median of 55.5 years (23-82 years). The Portuguese version of the QEQ had high internal consistency (Cronbach α=0.93), high stability between test and retest (ICC 0.83, with IC 95%: 0.76-0.88, p<0.001) and Spearman correlation coefficient r=0.82 (p<0.001), which demonstrated the high correlation between the QEQ and IIEF results. The correlations between the QEQ and RAND-36 were significantly low in ED (r=0.20, p=0.01) and non-ED patients (r=0.37, p=0.04). Conclusion The QEQ Portuguese version presented good psychometric properties and high convergent validity in relation to IIEF. The low correlations between the QEQ and the RAND-36, as well as between the IIEF and the RAND-36 indicated IIEF and QEQ specificity, which may have resulted from the patients’ psychological adaptations that minimized the impact of ED on Quality of Life (QoL) and reestablished the well

It is important to assess young children's perceived Fundamental Movement Skill (FMS) competence in order to examine the role of perceived FMS competence in motivation toward physical activity. Children's perceptions of motor competence may vary according to the culture/country of origin; therefore, it is also important to measure perceptions in different cultural contexts. The purpose was to assess the face validity, internal consistency, test-retest reliability and construct validity of the 12 FMS items in the Pictorial Scale for Perceived Movement Skill Competence for Young Children (PMSC) in a Portuguese sample. Two hundred one Portuguese children (girls, n = 112), 5 to 10 years of age (7.6 ± 1.4), participated. All children completed the PMSC once. Ordinal alpha assessed internal consistency. A random subsamples (n = 47) were reassessed one week later to determine test-retest reliability with Bland-Altman method. Children were asked questions after the second administration to determine face validity. Construct validity was assessed on the whole sample with a Bayesian Structural Equation Modelling (BSEM) approach. The hypothesized theoretical model used the 12 items and two hypothesized factors: object control and locomotor skills. The majority of children correctly identified the skills and could understand most of the pictures. Test-retest reliability analysis was good, with an agreement ration between 0.99 and 1.02. Ordinal alpha values ranged from acceptable (object control 0.73, locomotor 0.68) to good (all FMS 0.81). The hypothesized BSEM model had an adequate fit. The PMSC can be used to investigate perceptions of children's FMS competence. This instrument can also be satisfactorily used among Portuguese children. © 2016 John Wiley & Sons Ltd.

The present study was aimed at studying the physico-chemical and functional properties of 31 Portuguese common bean varieties. In addition, the whole bean flours (WBF) and starch isolates (SI) of three representative bean varieties and their rice: bean blends (70:30; 50:50) were assessed for amylose content, thermal and pasting properties in view of supplementation in rice based processed foods. Bean varieties showed significant differences in protein content (20.78-27.10%), fat content (1.16-2.18%), hydration capacity (95.90-149.30%), unhydrated seeds (4.00-40.00%), γ tocopherol (3.20-98.05 mg/100 g fat), δ tocopherol (0.06-4.72 mg/100 g fat) and pasting behavior. Amylose content of WBF (11.4-20.2%) was significantly lower than rice flour (23.51%) whereas SI of beans (40.00-47.26%) had significantly higher amylose content than SI of rice (28.13%). DSC results showed that WBF (11.4-20.2 °C) had significantly broader and lower gelatinization temperature range (∆Tr) than corresponding SI (20.9-23.1 °C). WBF had significantly lower pasting viscosity due to low starch content and compositional matrix effect as compared to SI. Setback viscosities of WBF and rice: bean blends was lower than rice flour. Low setback viscosities of rice:bean blends may be used to prevent syneresis and stabilizing the quality of frozen foods in rice based processed foods.

This paper evaluates the construct validity of the Medical Outcomes Study's social support scale adapted to Portuguese, when utilized in a cohort study among non-faculty civil servants at a university in Rio de Janeiro, Brazil (Pró-Saúde Study). Baseline data were obtained in 1999, when 4,030 participants (92.0% of those eligible) completed a multidimensional self-administered questionnaire at the workplace. From the original scale's five social support dimensions, factor analysis of the data extracted only three dimensions: positive social interaction/affective support; emotional/information support; and material support. We estimated associations between social support dimensions and socio-demographic, health, and well being-related characteristics. We confirmed the hypotheses that less isolated individuals, those with better self-rated health, those who reported more participation in group activities, and those with no evidence of common mental disorders reported better perception of social support. In conclusion, we found good evidence for a high construct validity of this scale, supporting its use in future analyses in the Pró-Saúde Study and in similar population groups.

The incidence of infection with HIV/AIDS among the heterosexual population has been increasing in young adults. The goal of this research was to deepen knowledge of preventive sexual behavior in Portuguese adolescents, including knowledge and attitudes about HIV/AIDS, and assessing whether they changed from 2002 to 2006. Data were collected through a self-administered questionnaire from the Portuguese sample of the Health Behavior in School-aged Children (HBSC), a collaborative WHO study. The study provides national representative data of 7093 Portuguese adolescents, randomly chosen from those attending 8th and 10th grade of high school. Results showed there was an increase in the age of first sexual intercourse and a decrease in the number of teenagers who reported having had sexual intercourse, also in the level of information regarding HIV/AIDS transmission/prevention and in positive attitudes towards people with HIV/AIDS. In general, adolescents have good knowledge about how to protect themselves from becoming infected. However, comparing to 2002, there was a reduction of knowledge and consequent increase in the doubts regarding HIV/AIDS. Given the incipient state of sex education in 2006, the results cannot be attributed to sex education, but they will be relevant for comparison with the 2010 HBSC results.

Hypertension is an extremely prevalent disease worldwide and hypertension control rates remain low. Lack of adherence contributes to poor control and to cardiovascular events. No questionnaire in Portuguese is readily available for the assessment of adherence to antihypertensive drugs. We aimed to perform a translation and cultural adaptation to Portuguese of the Hill-Bone Compliance to High Blood Pressure Therapy Scale, a validated instrument to measure adherence in hypertensive patients. A formal process was employed, consisting of a forward translation by two independent translators and a back translation by a third translator. Discrepancies were resolved after each step. Hypertensive patients were involved to identify and resolve phrasing and wording difficulties and misunderstandings. The forward and back translation did not produce significant discrepancies. However, important issues were identified when the questionnaire was presented to patients, which led to changes in the wording of the questions and in the format of the questionnaire. Questionnaires are important instruments to assess adherence to therapy, particularly in hypertension. A formal translation and cultural adaptation process ensures that the new version maintains the same concepts as the original. After translation, several changes were necessary to ensure that the questionnaire was understandable by elderly, low literacy patients, such as the majority of hypertensive patients. We propose a Portuguese version of the Hill-Bone Compliance Scale, which will require validation in further studies. Copyright © 2016 Sociedade Portuguesa de Cardiologia.

Ferreira, Lara N; Ferreira, Pedro L; Pereira, Luis N; Brazier, John; Rowen, Donna

2010-08-01

The SF-6D is a preference-based measure of health derived from the SF-36 that can be used for cost-effectiveness analysis using cost-per-quality adjusted life-year analysis. This study seeks to estimate a system weight for the SF-6D for Portugal and to compare the results with the UK system weights. A sample of 55 health states defined by the SF-6D has been valued by a representative random sample of the Portuguese population, stratified by sex and age (n = 140), using the Standard Gamble (SG). Several models are estimated at both the individual and aggregate levels for predicting health-state valuations. Models with main effects, with interaction effects and with the constant forced to unity are presented. Random effects (RE) models are estimated using generalized least squares (GLS) regressions. Generalized estimation equations (GEE) are used to estimate RE models with the constant forced to unity. Estimations at the individual level were performed using 630 health-state valuations. Alternative functional forms are considered to account for the skewed distribution of health-state valuations. The models are analyzed in terms of their coefficients, overall fit, and the ability for predicting the SG-values. The RE models estimated using GLS and through GEE produce significant coefficients, which are robust across model specification. However, there are concerns regarding some inconsistent estimates, and so parsimonious consistent models were estimated. There is evidence of under prediction in some states assigned to poor health. The results are consistent with the UK results. The models estimated provide preference-based quality of life weights for the Portuguese population when health status data have been collected using the SF-36. Although the sample was randomly drowned findings should be treated with caution, given the small sample size, even knowing that they have been estimated at the individual level.

2013-01-01

The purpose of the present study was to assess the factor structure and reliability of the Depression, Anxiety and Stress Scales (DASS-21) in a large Portuguese community sample. Participants were 1020 adults (585 women and 435 men), with a mean age of 36.74 (SD = 11.90) years. All scales revealed good reliability, with Cronbach's alpha values between .80 (anxiety) and .84 (depression). The internal consistency of the total score was .92. Confirmatory factor analysis revealed that the best-fitting model (*CFI = .940, *RMSEA = .038) consisted of a latent component of general psychological distress (or negative affectivity) plus orthogonal depression, anxiety and stress factors. The Portuguese version of the DASS-21 showed good psychometric properties (factorial validity and reliability) and thus can be used as a reliable and valid instrument for measuring depression, anxiety and stress symptoms.

To culturally adapt the Family Quality of Life Scale to the Brazilian Portuguese version and evaluate the instrument reliability and family quality of life of those who have children with hearing loss. The process of cultural adaptation of the scale followed the steps of the Guidelines for the Process of Cross-Cultural Adaptation of Self-Report Measure. It was conducted in three stages: translation, back translation, and application in a pilot sample, as a way to check the comprehension difficulties of the items. After it had been completed, it was administered to 41 families who have children with hearing loss and, with their results, the quality of life and reliability were analyzed based on the Cronbach's alpha statistical test. In the first version (translation), among the 25 items, there were differences between the translators only in four items; after the corrections, the second version was done (back translation), in which other four more differences were found. Finally, after the final corrections, the last version was developed and used in the pilot sample without differences. Thus, it was applied to families with deaf children, who believe to be satisfied as to their quality of life. The Cronbach's alpha test found that the scale shows a satisfactory reliability. The Brazilian Portuguese version of the Family Quality of Life Scale is a tool of easy use and satisfactory reliability. The families are satisfied with their family quality of life.

Sleepiness is considered to be a leading cause of crashes. Despite the huge amount of information collected in questionnaire studies, only some are based on representative samples of the population. Specifics of the populations studied hinder the generalization of these previous findings. For the Portuguese population, data from sleep-related car crashes/near misses and sleepiness while driving are missing. The objective of this study is to determine the prevalence of near-miss and nonfatal motor vehicle crashes related to sleepiness in a representative sample of Portuguese drivers. Structured phone interviews regarding sleepiness and sleep-related crashes and near misses, driving habits, demographic data, and sleep quality were conducted using the Pittsburgh Sleep Quality Index and sleep apnea risk using the Berlin questionnaire. A multivariate regression analysis was used to determine the associations with sleepy driving (feeling sleepy or falling asleep while driving) and sleep-related near misses and crashes. Nine hundred subjects, representing the Portuguese population of drivers, were included; 3.1% acknowledged falling asleep while driving during the previous year and 0.67% recalled sleepiness-related crashes. Higher education, driving more than 15,000 km/year, driving more frequently between 12:00 a.m. and 6 a.m., fewer years of having a driver's license, less total sleep time per night, and higher scores on the Epworth Sleepiness Scale (ESS) were all independently associated with sleepy driving. Sleepiness-related crashes and near misses were associated only with falling asleep at the wheel in the previous year. Sleep-related crashes occurred more frequently in drivers who had also had sleep-related near misses. Portugal has lower self-reported sleepiness at the wheel and sleep-related near misses than most other countries where epidemiological data are available. Different population characteristics and cultural, social, and road safety specificities may

Amusia is a disorder that affects the processing of music. Part of this processing happens in the primary auditory cortex. The study of this condition allows us to evaluate the central auditory pathways. To explore the diagnostic evaluation tests of amusia. The authors propose an evaluation protocol for patients with suspected amusia (after brain injury or complaints of poor musical perception), in parallel with the assessment of central auditory processing, already implemented in the department. The Montreal Evaluation of Battery of amusia was the basis for the selection of the tests. From this comprehensive battery of tests we selected some of the musical examples to evaluate different musical aspects, including memory and perception of music, ability concerning musical recognition and discrimination. In terms of memory there is a test for assessing delayed memory, adapted to the Portuguese culture. Prospective study. Although still experimental, with the possibility of adjustments in the assessment, we believe that this assessment, combined with the study of central auditory processing, will allow us to understand some central lesions, congenital or acquired hearing perception limitations.

The persistence of Listeria monocytogenes in food-associated environments represents a key factor in transmission of this pathogen. To identify persistent and transient strains associated with production of fermented meat sausages in northern Portugal, 1,723 L. monocytogenes isolates from raw material and finished products from 11 processors were initially characterized by random amplification of polymorphic DNA (RAPD), PCR-based molecular serotyping, and epidemic clone characterization, as well as cadmium, arsenic, and tetracycline resistance typing. Pulsed-field gel electrophoresis (PFGE) typing of 240 representative isolates provided evidence for persistence of L. monocytogenes for periods of time ranging from 10 to 32 months for all seven processors for which isolates from different production dates were available. Among 50 L. monocytogenes isolates that included one representative for each PFGE pattern obtained from a given sample, 12 isolates showed reduced invasion efficiency in Caco-2 cells, including 8 isolates with premature stop codons in inlA. Among 41 isolates representing sporadic and persistent PFGE types, 22 isolates represented lysogens. Neither strains with reduced invasion nor lysogens were overrepresented among persistent isolates. While the susceptibility of isolates to lysogenic phages also did not correlate with persistence, it appeared to be associated with molecular serotype. Our data show the following. (i) RAPD may not be suitable for analysis of large sets of L. monocytogenes isolates. (ii) While a large diversity of L. monocytogenes subtypes is found in Portuguese fermented meat sausages, persistence of L. monocytogenes in this food chain is common. (iii) Persistent L. monocytogenes strains are diverse and do not appear to be characterized by unique genetic or phenotypic characteristics. PMID:21378045

Objectives To characterise the test ordering pattern in Northern Portugal and to investigate the influence of context-related factors, analysing the test ordered at the level of geographical groups of family physicians and at the level of different healthcare organisations. Design Cross-sectional study. Setting Northern Primary Health Care, Portugal. Participants Records about diagnostic and laboratory tests ordered from 2035 family physicians working at the Northern Regional Health Administration, who served approximately 3.5 million Portuguese patients, in 2014. Outcomes To determine the 20 most ordered diagnostic and laboratory tests in the Northern Regional Health Administration; to identify the presence and extent of variations in the 20 most ordered diagnostic and laboratory tests between the Groups of Primary Care Centres and between health units; and to study factors that may explain these variations. Results The 20 most ordered diagnostic and laboratory tests almost entirely comprise laboratory tests and account for 70.9% of the total tests requested. We can trace a major pattern of test ordering for haemogram, glucose, lipid profile, creatinine and urinalysis. There was a significant difference (P<0.001) in test orders for all tests between Groups of Primary Care Centres and for all tests, except glycated haemoglobin (P=0.06), between health units. Generally, the Personalised Healthcare Units ordered more than Family Health Units. Conclusions The results from this study show that the most commonly ordered tests in Portugal are laboratory tests, that there is a tendency for overtesting and that there is a large variability in diagnostic and laboratory test ordering in different geographical and organisational Portuguese primary care practices, suggesting that there may be considerable potential for the rationalisation of test ordering. The existence of Family Health Units seems to be a strong determinant in decreasing test ordering by Portuguese family

People with schizophrenia have low physical activity levels that can be explained by the restriction in motivation. The Behavioural Regulation in Exercise Questionnaire-2 is a 19-item scale commonly used to assess five different motivational subtypes for physical activity. However, there are limited psychometric analyses of this version in the schizophrenia context. Moreover, there is a lack of information related to the psychometric properties of version 3 of this questionnaire, with 24 items and six different motivational subtypes. The aim of this study was to examine the construct validity of both Portuguese versions in people with schizophrenia. A total of 118 persons with schizophrenia were included (30 women). Cronbach's alpha was used for internal consistency, Pearson's correlation for the retained motivation-types, confirmatory factor analysis for the structural validity of version 2 and exploratory factor analysis for the factor structure of version 3. Analyses of version 2 provided an adequate fit index for the structure of the five factors. Exploratory analyses suggested retaining 2 factors of version 3. The results of this study suggest that version 3 was an appropriate measure to assess controlled and autonomous motivation for physical activity in people with schizophrenia and support its use in clinical practice and research. Implications for Rehabilitation This study supports the need to identify the reasons why people with schizophrenia practice physical activity. For that purpose, it is important to use valid and cost-effective instruments. The Portuguese version of BREQ-2 confirmed a 5-factor model and showed adequate fit for the application in people with schizophrenia. However, the incremental indices values were lower than expected. The Portuguese version of BREQ-3 showed acceptable psychometric properties to assess controlled and autonomous motivation for physical activity in people with schizophrenia.

Our aim was to analyse the linguistic structure of the Lobrot's Lecture 3 (L3) reading test and to describe the procedure for its adaptation to a Brazilian cultural-linguistic context. The resulting adapted version is called the Reading Test-Sentence Comprehension [Teste de Leitura: Compreensão de Sentenças (TELCS)] and was developed using the European Portuguese adaptation of L3 as a reference. The present study was conducted in seven steps: (1) classification of the response alternatives of L3 test; (2) adaptation of the original sentences into Brazilian Portuguese; (3) back-translation; (4) adaptation of the distractors from TELCS; (5) configuration of TELCS; (6) pilot study; and (7) validation and standardization. In comparison with L3, TELCS included new linguistic and structural variables, such as frequency of occurrence of the distractors, gender neutrality and position of the target words. The instrument can be used for a collective screening or individual clinical administration purposes to evaluate the reading ability of second-to-fifth-grade and 7-to-11-year-old students.

Antunes, Ana Cristina; Caetano, António; Pina E Cunha, Miguel

2017-06-01

The Psychological Capital Questionnaire (PCQ) is the most commonly used measure for assessing psychological capital in work settings. Although several studies confirmed its factorial validity, most validation studies only examined the four-factor structure preconized by Luthans, Youssef, and Avolio, not attending to empirical evidence on alternative factorial structures. The present study aimed to test the psychometric properties of the Portuguese version of the PCQ, by using two independent samples (NS1 = 542; NS2 = 115) of Portuguese employees. We conducted a series of confirmatory factor analyses and found that, unlike previous findings, a five-factor solution of the PCQ best fitted the data. The evidence obtained also supported the existence of a second-order factor, psychological capital. The coefficients of internal consistency, as measured by Cronbach's alpha, were adequate and test-retest reliability suggested that the PCQ presented a lower stability than personality factors. Convergent validity, assessed with average variance extracted, revealed problems in the optimism subscale. The discriminant validity of the PCQ was confirmed by its correlations with Positive and Negative Affect and Big Five personality factors. Hierarchical regression analyses showed that this measure has incremental validity over personality and affect when predicting job performance.

Personal conceptions of intelligence, self-esteem, and school achievement in Italian and Portuguese students.

Educational research places emphasis on the fact that different cultures have different self-construals. These construals can influence cognitive, emotional, and motivational processes in individuals. Great importance is attached to individuals' implicit conceptions of the nature of their intelligence (incremental or entity) and self-esteem. In general, both representation of intelligence and self-esteem seem to play an important role in scholastic performance in terms of both a predispostion to learning and the results actually achieved. The aim of this research is to determine the relationship between variables such as school, and socioeconomic level and gender in Italian and Portuguese students. A questionnaire was administered to 1,540 high school and university students assessing socioeconomic level and school performance, the Personal Conceptions of Intelligence Test (Faira & Fontaine, 1997), and the Self-Esteem Test (Rosenberg, 1965). In general, results show that Portuguese subjects are more incremental than Italians. Moreover, significant differences have to be determined regarding motivational factors linked to school and socioeconomic level and gender. The research highlights the importance of macro-contextual factors in the social, economic, and political organizations that influence how people develop their motivational beliefs.

The present study aims to analyze the psychometric properties of the student form (Grades 7 to 12) of the Social Skills Questionnaire authored by Gresham and Elliott (1990), on a sample of Portuguese adolescents. Participants included 573 students, both female and male, aged 14 to 19. Reliability was assessed through Cronbach's alpha and was .87 for the total scale, ranging from.58 to .72 for the subscales. A confirmatory factor analysis revealed that the main adjustment indices presented unexpected values. A principal components analysis indicated that several items of the cooperation subscale correlated with other factors. Adequate adjustment indices were found when cooperation was removed from the model. Semantic dualities due to cultural factors and difficulties assuming the cooperation dimension as an independent dimension might explain the results observed. The reorganization of the SSQ offers a reliable and valid instrument for research within the Portuguese population.

[News on the trip and the diplomatic mission of a Portuguese ambassador to China in 1752. Critical and analytical study].

The author of this report has worked out a critical-analytical study, based on the news of a voyage to China, carried out by a Portuguese ambassador, which was also a diplomatic mission, in 1752, during the Marquis of Pombal era, Prime Minister of king Dom Jose I. This study is directed under two perspectives: medical and historical-diplomatic. The former not only allows the assessment of the high degree of organization of this voyage as far as food supplies and medical support are concerned, but it also shows the reflection and the diagnosis correction of tuberculosis of the lungs, in a seaman, carried out by a surgeon on board, which we totally refute. The latter, which only aims at giving some further data for the study of the Portuguese Diplomatic History, let us know some of the complex procedures and protocols established between our diplomatic representative and the high Chinese rulers, both the Emperor himself and the mandarins. Contrary to other previous attempts of diplomatic, economic and social relations, either partially or totally frustrated, this mission constituted a great success for Portugal and may, indeed, be considered as a decisive step for the recognition of Portuguese sovereignty over the territory of Macao and its dependencies in 1887.

BACKGROUND atopic dermatitis is directly related to psychological stress, reduced quality of life and psychosomatic symptoms. The Psychosomatic Scale for Atopic Dermatitis is the only questionnaire developed specifically for assessment of psychosomatization in atopic dermatitis. OBJECTIVES the objective of this study was to cross-culturally adapt and validate a Brazilian-Portuguese version of the Psychosomatic Scale for Atopic Dermatitis. METHODS adaptation consisted of independent translation and backtranslation by three bilingual translators, followed by a pre-test. The Psychosomatic Scale for Atopic Dermatitis and the Dermatology Life Quality Index were self-administered to 47 patients with atopic dermatitis. Disease severity was evaluated using the Eczema Area and Severity Index. Factor analysis was used to identify the dimensions of the Brazilian Portuguese version of the Psychosomatic Scale for Atopic Dermatitis. Internal consistency and convergence validity were also analyzed. Reproducibility was assessed using the Kappa coefficient. RESULTS factor analysis revealed a two-dimensional structure: stress/laziness/insecurity (I) and maladjustment/social relationships (II), explaining 54.4% of total variance. All dimensions revealed excellent internal consistency. External construct validity was confirmed by positive correlations between the Psychosomatic Scale for Atopic Dermatitis and the Dermatology Life Quality Index. Test-retest reliability was excellent, with k>0.7 for all questions. CONCLUSIONS the Brazilian Portuguese version of the Psychosomatic Scale for Atopic Dermatitis demonstrated acceptable psychometric properties and can be used for the evaluation of psychosomatic symptoms in patients with atopic dermatitis and as a tool in clinical and epidemiological research.

The purpose of this study was to analyse Portuguese coaches' perceptions of, and preferences for, knowledge sources as related to professional background; namely academic education level, coach education level and coaching experience. The study's participants comprised 336 Portuguese coaches from twenty-two sports. A questionnaire was used to identify coaches' demographic characteristics and representations about their preferred sources of coaching knowledge. MANOVA using Tukey's HSD test was used to compare groups. The results highlighted that coaches perceived that coaching knowledge is built from a broad range of sources from personal coaching and playing experiences to more explicit formal, informal and non-formal learning situations. Results indicated that the coaches ascribed more importance to experiential sources such as working with experts, learning by doing, interacting with peer coaches and attending informal seminars and clinics, than to the formal learning situations provided by the national coaching certification programs. Differences, however, were found in that coaches who had a greater background within higher education (physical) and sport valued informal and non-formal learning sources more than did coaches who were defined as not coming from an academic background. The findings point to the importance of developing new learning, experientially-based, opportunities within the Portuguese context, where curricula content continues to be delivered via didactic means. Key pointsCoaches recognized that learning is obtained from a broad range of sources of coaching knowledge and each source has a particular role in the development of a coach.Experiential guided sources reached more importance to coaches as working with experts, learning by doing, attending seminars/clinics outside of the formal system and interaction with peers were the most acknowledged.The only source that is related to formal learning, national certification programs, was

Enabling patients with asthma to obtain the knowledge, confidence and skills they need in order to assume a major role in the management of their disease is cost effective. It should be an integral part of any plan for long-term control of asthma. The modified Patient Enablement Instrument (mPEI) is an easily administered questionnaire that was adapted in the United Kingdom to measure patient enablement in asthma, but its applicability in Portugal is not known. Validity and reliability of questionnaires should be tested before use in settings different from those of the original version. The purpose of this study was to test the applicability of the mPEI to Portuguese asthma patients after translation and cross-cultural adaptation, and to verify the structural validity, internal consistency and reproducibility of the instrument. The mPEI was translated to Portuguese and back translated to English. Its content validity was assessed by a debriefing interview with 10 asthma patients. The translated instrument was then administered to a random sample of 142 patients with persistent asthma. Structural validity and internal consistency were assessed. For reproducibility analysis, 86 patients completed the instrument again 7 days later. Item-scale correlations and exploratory factor analysis were used to assess structural validity. Cronbach's alpha was used to test internal consistency, and the intra-class correlation coefficient was used for the analysis of reproducibility. All items of the Portuguese version of the mPEI were found to be equivalent to the original English version. There were strong item-scale correlations that confirmed construct validity, with a one component structure and good internal consistency (Cronbach's alpha >0.8) as well as high test-retest reliability (ICC=0.85). The mPEI showed sound psychometric properties for the evaluation of enablement in patients with asthma making it a reliable instrument for use in research and clinical practice in

Portugal has one of the highest rates of childhood overweight and obesity in Europe. However, little is known about the health of ethnic minorities living in its capital city, Lisbon. The Cape Verdean community in Lisbon tend to have low educational levels, material deprivation and struggle with discrimination and racism, factors that would probably be associated with a higher prevalence of overweight and obesity. Data for the Cape Verdean population were collected in three different time periods by three different research teams in 1993, 2009 and 2013 and included children aged 6-12 years living in the Cova da Moura neighbourhood of the Greater Lisbon Metro Area. The Portuguese national survey was conducted between 2009 and 2010 at public and private schools in mainland Portugal and included height, weight, skinfolds and arm and waist circumferences. From these survey data body mass index (BMI) and prevalence of stunting (chronic malnutrition - low height-for-age) and underweight (low weight-for-age) were calculated according to reference values proposed by Frisancho (2008). Overweight and obesity prevalence values were defined based on the references established by the International Obesity Task Force. The results show significant differences in height between Cape Verdean and Portuguese boys and girls. Generally, Cape Verdeans' growth falls within the healthy range of international growth references across all of the survey data collected. Cape Verdean rates for combined overnutrition (overweight and obesity) in 2013 (9.8% for boys and 16.7% for girls) were lower than those of the Portuguese (33% for boys and 31.7% for girls). Logistic regression models showed that Cape Verdean children had a lower risk of being overweight or obese when accounting for breast-feeding, birth weight, maternal education and occupation. Despite living in a deprived neighbourhood these Cape Verdean children seemed to have grown more healthily than Portuguese ancestry children. The

Inadequate sleep patterns and insomnia are frequently linked and represent common sleep disorders among adolescents. The present study provides data on sleep patterns and insomnia among Portuguese adolescents. In a cross-sectional study we evaluated 6,919 students from the 7th to the 12th grade from twenty-six secondary schools. Data was collected using a self-administered questionnaire. Insomnia was defined based on the Diagnostic and Statistical Manual of Mental Disorders IV criteria and daytime sleepiness was assessed with the Epworth Sleepiness Scale. Sleep patterns evaluated both sleep duration ("insufficient" sleep was defined as < 8 hours per night) and bedtime schedules and regularity. The prevalence of insomnia was 8.3%, insomnia symptoms 21.4% and insufficient sleep 29.3%. All prevalence were higher among girls (P<.001). Average sleep time, on weeknights, was 8:04±1:13 hours. On average adolescents went to bed at 22:18±1:47 hours, took 21 minutes to fall asleep and woke up at 7:15±0:35 hours. Only 6.4% of adolescents stated having a regular bedtime. The majority of adolescents (90.6%) reported having difficulty waking up, 64.7% experienced daytime sleepiness and 53.3% experienced sleep during classes. There are high prevalence of inadequate sleep patterns, insufficient sleep and insomnia among Portuguese adolescents. Insufficient sleep is associated with sleep patterns and social and behavioural factors. These results add to our knowledge of adolescent sleep worldwide. Copyright © 2014 Elsevier España, S.L.U.

Cyanobacteria blooms are frequent in freshwaters and are responsible for water quality deterioration and human intoxication. Although, not a new phenomenon, concern exists on the increasing persistence, scale, and toxicity of these blooms. There is evidence, in recent years, of the transfer of these toxins from inland to marine waters through freshwater outflow. However, the true impact of these blooms in marine habitats has been overlooked. In the present work, we describe the detection of Planktothrix agardhii , which is a common microcystin producer, in the Portuguese marine coastal waters nearby a river outfall in an area used for shellfish harvesting and recreational activities. P. agardhii was first observed in November of 2016 in seawater samples that are in the scope of the national shellfish monitoring system. This occurrence was followed closely between November and December of 2016 by a weekly sampling of mussels and water from the sea pier and adjacent river mouth with salinity ranging from 35 to 3. High cell densities were found in the water from both sea pier and river outfall, reaching concentrations of 4,960,608 cells·L -1 and 6810.3 × 10⁶ cells·L -1 respectively. Cultures were also established with success from the environment and microplate salinity growth assays showed that the isolates grew at salinity 10. HPLC-PDA analysis of total microcystin content in mussel tissue, water biomass, and P. agardhii cultures did not retrieve a positive result. In addition, microcystin related genes were not detected in the water nor cultures. So, the P. agardhii present in the environment was probably a non-toxic strain. This is, to our knowledge, the first report on a P. agardhii bloom reaching the sea and points to the relevance to also monitoring freshwater harmful phytoplankton and related toxins in seafood harvesting and recreational coastal areas, particularly under the influence of river plumes.

Background Scientific literature estimates that around 18 to 40 % of asymptomatic third molars are extracted. The aims of the present study were to determine the indications for extraction of asymptomatic lower third molars in a sample of Spanish and Portuguese dentists, and to relate these indications to the clinicians’ training and professional experience. Material and Methods A survey consisting of 15 cases of asymptomatic lower third molars was emailed to Portuguese and Spanish dentists. The clinicians were asked to assess the level of difficulty of the extractions and to make a reasoned recommendation based on the panoramic radiographs, gender and age of the patients. Results 381 clinicians filled in the questionnaires. Most of the professionals had over 13 years of clinical experience. The number of Spanish clinicians with postgraduate degrees in Oral Surgery was significantly higher. On average, 42% of respondents recommended extraction of asymptomatic third molars. The indication for extraction was significantly higher among Portuguese dentists. Clinical experience was negatively correlated with the perceived extraction difficulty (p<0.05). The main reason given for extracting was the prevention of pericoronitis, whereas that for not extracting was the absence of a clear indication and the risk of injuring the inferior alveolar nerve. Conclusions The Portuguese dentists were more in favour of removing asymptomatic lower third molars than the Spanish dentists, although the latter had a higher proportion of professionals with postgraduate studies in Oral Surgery.

Physalia physalis, commonly known as the Portuguese man-of-war (PMW), is a peculiar looking colony of specialized polyps. The most conspicuous members of this colony are the gas-filled sail-like float and the long tentacles, budding asymmetrically beneath the float. This study addresses the sailing of the PMW, and, in particular, the hydrodynamics of its trailing tentacles, the interaction between the tentacles and the float and the actual sailing performance. This paper attempts to provide answers for two of the many open questions concerning P. physalis: why does it need a sail? and how does it harness the sail? PMID:19091687
