Portraying the Portuguese Foundation Sector: a financial statement analysis
Foundations’ importance in the actual economy has been increasingly recognized. This work
project assesses the impact of the new legal framework in the foundations’ financial reporting
and offers a financial statement analysis of the Portuguese foundational sector. It unveils links
between financial performance and characteristics of foundations, and profiles foundations in
three clusters, each with different approaches to disclosure, volunteer workforce, and taxes. It
is concluded that foundations are not respecting the benefits trusted to them, calling for a tighter
control to their financial reporting, and that even though that slowly, the sector is expected to
continue growing
Is holistic processing of written words modulated by phonology?
Holistic processing, a hallmark of face processing, has been shown for written words, signaled by the word composite effect. Fluent readers find it harder to focus on one half of a written word (e.g., the first syllable of a CV.CV word) while ignoring the other half (e.g., the second syllable), especially when the two halves are aligned rather than misaligned. Given the linguistic nature of written words, in the present study, we examined whether the word composite effect is modulated by phonology. In Experiment 1, participants saw two sequentially presented CV.CV words and had to decide if the left half (first syllable) was the same or not, regardless of the right half. The word pairs were either phonologically consistent (univocal orthography to phonology mapping; e.g., TI is always /ti/ in Portuguese) or inconsistent (orthography can map into different phonological representations; e.g., CA can correspond to /ka/ or /kɐ/). The word composite effect was found for phonologically consistent words but not for phonologically inconsistent words. In Experiment 2, timing of trial events was reduced to test whether the influence of phonology was fast and automatic. Similar to what was found in Experiment 1, the word composite effect was found only for phonologically consistent words. The faster trial events in Experiment 2 rendered it less likely that the influence of phonology in word composite effect is merely a result of strategic processing. These findings suggest that holistic processing of visual words is modulated by fast and automatic activation of lexical phonological representations
Phenolic compounds and bioactive properties of Ruscus aculeatus L. (asparagaceae): the pharmacological potential of an underexploited subshrub
Ruscus aculeatus L. is a subshrub used in traditional medicine in different parts of the world, namely in Europe and the Iberian Peninsula. According to reported folk knowledge, the aerial parts are mainly used as diuretics and the underground organs are used for the treatment of disorders of the urinary system and as a laxative. In this work, the aerial part and the roots and rhizomes of R. aculeatus were chemically characterized with regard to the content of phenolic compounds and bioactive properties. Aqueous (infusions and decoctions) preparations and hydroethanolic extracts from the two mentioned parts of the plant were prepared. Nine phenolic compounds were detected in all the extracts. Apigenin-C-hexoside-C-pentoside isomer II was the major compound in aqueous extracts and, in the hydroethanolic extract was quercetin-O-deoxyhexoside-hexoside followed by apigenin-C-hexoside-C-pentoside isomer II. All extracts revealed antioxidant activity and potential to inhibit some of the assayed bacteria; aqueous extracts of the aerial part and infusions of roots and rhizomes did not show cytotoxic effects on a non-tumor primary cell culture. This preliminary study provides suggestions of the biological potential associated with the empirical uses and knowledge of this species, in particular its bioactivities.The authors are grateful to the Foundation for Science and Technology (FCT, Portugal)

Bioactive properties of Ruscus aculeatus L.: na underexploited subshrub
Ruscus aculeatus L. is a sub-shrub used in traditional medicine in different parts of the world,
namely in Europe and the Iberian Peninsula[1]. Traditionally, the aerial parts are mainly used as
diuretics and the underground parts are used for the treatment of urinary tract diseases and as a
laxative[2]. In the present work, the aerial part, roots, and rhizomes of R. aculeatus were
characterized regarding their bioactive properties in order to contribute to the knowledge of the
chemical composition of this unexplored species. The plant material of R. aculeatus was
harvested in April 2019 inside woodlands and hedgerows, in Valpaços, Portugal. Two distinct
parts were gathered: the aerial part (cladodes or laminar stems and lateral branches) and the
underground organs (rhizomes with roots). Hydroethanolic extracts and aqueous (infusions and
decoctions) preparations from the two mentioned parts of the plant were prepared.
Multi-resistant clinical bacterial strains (Enterococcus faecalis, Listeria monocytogenes,
methicillin-resistant Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae,
Morganela morganii, Proteus mirabilis and Pseudomonas aeruginosa) were used to screen the
antimicrobial activity and the antioxidant activity was evaluated through two different in vitro
assays: inhibition of lipid peroxidation in brain homogenates by thiobarbituric acid reactive
substances (TBARS) and oxidative hemolysis inhibition assay (OxHLIA). The cytotoxic
activity was assayed using MCF-7 (breast adenocarcinoma), NCI-H460 (non-small cell lung
carcinoma), HeLa (cervical carcinoma) and HepG2 (hepatocellular carcinoma) human tumor
cell lines, and also a non-tumor cell line (porcine liver primary cells, PLP2). All extracts
revealed antioxidant activity and potential to inhibit some of the assessed bacteria; except for
the infusion of the aerial part (for the lines MCF7 and HepG2) and decoction extracts (line
MCF7), all the remaining extracts presented effective results in the inhibition of the tested cell
lines; the aqueous extracts of the aerial part and infusions of roots and rhizomes did not show
cytotoxic effects in a non-tumor primary cell culture. This preliminary study provided
innovative and interesting results in relation to the bioactive properties of this little-studied and
explored wild plant.The authors are grateful to the Foundation for Science and Technology

Valorization of cereal by-products from the milling industry as a source of nutrients and bioactive compounds to boost resource-use efficiency
Cereal by-products (wheat germ, maize bran–germ mixture, rye bran, and wheat bran) from the flour milling industry were characterized for their nutritional value and chemical composition, as well as for antioxidant and antibacterial activities. Carbohydrates (including sucrose) were the major nutritional constituents (56.35–78.12 g/100 g dw), followed by proteins (11.2–30.0 g/100 g dw). The higher energy value (432.3 kcal/100 g dw) was presented by the wheat germ. This by-product also presented the highest citric acid content (0.857 g/100 g dw), the most abundant organic acid detected. Unsaturated fatty acids predominated in all samples given the high content of linoleic (53.9–57.1%) and oleic (13.4–29.0%) acids. Wheat germ had the highest levels of tocopherols (22.8 mg/100 g dw) and phenolic compounds (5.7 mg/g extract, with a high apigenin-C-pentoside-C-hexoside content). In turn, while the wheat bran extract was particularly effective in inhibiting the formation of thiobarbituric acid reactive substances (TBARS), the rye bran extract was the only sample capable of protecting erythrocytes from oxidative hemolysis. Regarding antibacterial properties, in general, the lowest minimum inhibitory concentrations were observed against methicillin-resistant Staphylococcus aureus. These results highlight the characterized by-products as sustainable ingredients for the development of novel bakery and functional food products and contribute to a better bioresource-use efficiency and circularity.The authors are grateful to the Foundation for Science and Technology (FCT, Portugal)

Chemical and bioactive characterization of the aromatic plant Levisticum officinale W.D.J. Koch: a comprehensive study
Aromatic plants have been used since antiquity as seasoning ingredients to impart unique flavours to
foods, and also as folk medicines, and are currently used as a source of several compounds of interest for
different industries. Lovage (Levisticum officinale W.J.D. Koch) is an aromatic plant from the Apiaceae
family with a strong flavour that has long been used in culinary products, in traditional medicine and by
the food industry. Despite its significance and relevance, apart from its composition in volatile compounds,
there is a scarcity of information about this plant species. To the best of our knowledge, this
study documents for the first time the nutritional value and composition in fatty acids, organic acids and
tocopherols of the edible aerial part of lovage, evidencing a low caloric value, a predominance of polyunsaturated
fatty acids, mainly α-linolenic acid, oxalic acid as the most abundant organic acid and
α-tocopherol as the most abundant vitamin E isoform. The essential oil was mainly characterised by the
presence of monoterpenes, showing also a high abundance of phthalides. In addition, a total of 7 phenolic
compounds were identified in the decoction and hydroethanolic extracts, which showed interesting
antioxidant properties and bacteriostatic activity, particularly against Gram-positive bacteria. Only the
decoction showed cytotoxicity against a tumoral cell line (HepG2).The authors are grateful to the Foundation for Science and

Polyphenol composition by HPLC-DAD-(ESI-)MS/MS and bioactivities of extracts from grape agri-food wastes
Background: Grape agri-food wastes, such as skin, seeds, and other discarded by-products, contain phytochemical compounds that offer potential health benefits. Methods: This study aimed to investigate the polyphenol composition and bioactivities of different extracts obtained from grape marc and seeds, with the goal of exploring their potential for application as natural food additives. Results: Regardless of the extraction method used (dynamic maceration, ultrasound-assisted extraction (UAE), and microwave-assisted extraction (MAE)), all extracts exhibited relatively high concentrations of phenolic compounds. The chemical characterization of the extracts revealed the presence of specific compounds and chemical groups associated with each extraction methodology. Moreover, the extracts displayed satisfactory antioxidant activities, especially in inhibiting lipoperoxidation as assessed by the TBARS assay. Additionally, the extracts demonstrated effective inhibition against different strains of bacteria and fungi known as food contaminants. Taken together, these findings indicate that those extracts have the potential to be tested as natural antioxidants and preservatives with sustainable origins in food and beverage systems. Among the extraction methods evaluated, traditional maceration and UAE provided extracts with the highest antioxidant and antimicrobial activities. Conclusions: Our results suggest the opportunity to explore grape marc and seeds discarded by the winery industry in Portugal as natural sources of bioactive compounds, which could be employed as functional food ingredients or technological additives. The valorization of grape biowastes offers a promising strategy to reduce waste and harness their potential health benefits.Authors acknowledge the Foundation for Science and Technology (FCT, Portugal),

Hábitos Alimentares das Pessoas com Diabetes Mellitus Tipo 2 em Portugal: Um Estudo Transversal
Introdução: A nutrição é uma área de intervenção na prevenção e gestão da diabetes mellitus; por isso, é fulcral promover a capacitação da população para a adoção de hábitos alimentares saudáveis. Ainda que existam alguns estudos nesta área, não se conhecem os principais erros nos hábitos alimentares das pessoas com diabetes em Portugal. Os objetivos deste estudo foram identificar os principais erros nos hábitos alimentares das pessoas com diabetes mellitus tipo 2 em Portugal e avaliar a sua relação com variáveis sociodemográficas.
Métodos: Estudo transversal multicêntrico, em amostra de conveniência de pessoas com diabetes mellitus tipo 2 seguidas em Unidades de Cuidados de Saúde Primários. Aplicação do UK Diabetes and Diet Questionnaire (UKDDQ) – traduzido e adaptado, de julho a outubro de 2022. Análise estatística descritiva e inferencial.
Resultados: Amostra de 550 participantes, 52,2% do sexo feminino, 68,3% com 65 anos ou mais, 55,8% com nível de escolaridade igual ou inferior ao 1.º ciclo do ensino básico, 24,7% com insuficiência económica e tempo desde o diagnóstico médio de 10,60 ± 8,13 anos. Apenas 36,2% da amostra obteve um score UKDDQ considerado saudável. Menos de 50% obteve scores saudáveis para os itens “arroz ou massa ricos em fibras”, “pão integral”, “manteiga, margarina e óleos vegetais” e “vegetais e leguminosas”. Somente 8,9% da amostra obteve score saudável para o consumo de fibras. Cerca de 70,4% obteve score saudável para o consumo de açúcares livres e 54,7% para o consumo de ácidos gordos saturados. Verificou-se a existência de uma correlação com significado estatístico positiva fraca entre o score UKDDQ e a idade (ρ = 0,201, p < 0,001), com escolha mais frequente de alimentos saudáveis com o aumentar da idade. As pessoas do sexo feminino reportaram hábitos alimentares mais saudáveis, particularmente no consumo de fibras e ácidos gordos saturados.
Conclusão: A maior parte da nossa amostra não usufruiu do potencial efeito positivo de uma alimentação saudável. Individualizam-se grupos de alimentos cujos consumos devem ser enfatizados ou desencorajados, particularmente, a necessidade de incentivar o consumo de alimentos ricos em fibra. Ações educacionais dirigidas devem ter especial foco em pessoas mais jovens e/ou do sexo masculino
Influenza severe cases in hospitals, between 2014 and 2016 in Portugal
Rede Portuguesa de Laboratórios para o Diagnóstico da GripeBackground: Since 2009, the Portuguese Laboratory Network (PLNID) for Influenza Diagnosis has integrated 15 Laboratories in mainland and Atlantic Islands of Azores and Madeira. This PLNID added an important contribute to the National Influenza Surveillance Program regarding severe and hospitalized influenza cases. The present study aims to describe influenza viruses detected in influenza like illness (ILI) cases: outpatients (Outp), hospitalized (Hosp), and intensive care units (ICU), between 2014 and 2016.
Methods: The PLNID performs influenza virus diagnosis by biomolecular methodologies. Weekly reports to the National Influenza Reference Laboratory ILI cases tested for influenza. Reports include data on detecting viruses, hospital assistance, antiviral therapeutics, and information on death outcome. Were reported during two winter seasons 8059 ILI cases,being 3560 cases in 2014/15 (1024 in Outp, 1750 Hosp, and 606 in ICU) and 4499 cases in 2015/2016 (1933 in Outp, 1826 Hosp, and 740 in ICU).
Results: The higher percentage of influenza positive cases were detected in Outp in both seasons, 18% during 2014/15 and 20% in 2015/16. In 2014/15,influenza cases were more frequent in individuals older than 65 years old and these required more hospitalizations,even in ICU. In 2015/16,the influenza cases were mainly detected in individuals between 15-64 years old. A higher proportion of influenza positive cases with hospitalization in ICU were observed in adults between 45-64 years old.During the study period,the predominant circulating influenza viruses were different in the two seasons: influenza B and A(H3) co-circulated in 2014/15,and influenza A(H1)pdm09 was predominant during 2015/16. Even when influenza A is notthe dominant virus, A(H3) and A(H1)pdm09 subtypes correlate with higher detection rate in hospitalized cases (Hosp and UCI), with higher frequencies in adults older than 45. Influenza B,detected in higher proportion in outpatients, was frequently relatedwith influenza cases in younger age groups: 0-4 and 5-14 years old.
Conclusions: This study highlights the correlation of theinfluenza virus type/subtype that circulates in each season with the possible need for hospitalization and intensive care in special groups of the population. Circulation of influenza A subtypes can cause more frequentdisease in individuals older than 45, with need of hospitalization including intensive care. On the other hand, influenza B is more frequently associated with less severe cases and with infection in children and younger adults. Influenza B circulation might predict lower number of hospitalizations.The identification of influenza type in circulation,byPLNID ineach season, could guide action planning measures in population health care.info:eu-repo/semantics/publishedVersio
