- Home and Leisure Accidents in children and young people from 0 to 19 years old in Portugal. 2018Publication . Alves, Tatiana; Rodrigues, Emanuel; Neto, Mariana; Mexia, Ricardo; Matias-Dias, CarlosInjuries and accidents are a challenge for public health considering their impact on victims and their families, especially in the younger, and also the potential for prevention and predictability. Due to specific characteristics of children and young persons related to the need of exploration and curiosity injuries namely those occur in domestic and leisure time, including the school setting are a topic of particular interest and study. This study aimed to characterize the occurrence of Home and Leisure Accidents (HLA) using hospital Emergency Department (ED) registered in EVITA system, in victims between 0 and 19 years old considering the injury mechanism, place of occurrence and products involved in the accident, in 2018, in Portugal Were analysed data from the EVITA system, fed by the HLA registry at the ED of the Hospitals National Health that participate in this system. The frequency and distribution of HLA were analysed according to the injury mechanism, place of occurrence and products involved. In 2018, there were 38 528 ED attendances due to HLA 35,0% of the victims were between 10-14 years old; 23,7% had 5-9 years; 22,8% between 15 and 19 years old and 18,5% had under 4 years old. The results show more frequently HLA in males (59,0%) than in females (41,0%). In children under 4 years old 67,8% of the HLA occurred at home, due to fall (68,6%), having as products most involved the bed (10,2%) and chair or bench (7,5%). Between 5 and 9 years old, most HLA occurred at school (44,5%) due to fall (62,9%), involving ball (15,1%) and scooter/tricycle/bike (6,8%). In young people between 10 and 19 years old 47,7% of HLA occurred at school, due to fall (54,6%), having as main agents involved ball (28,7%) and scooter/tricycle/bike (20,3%). This information reinforces the importance of this problem but it is necessary future lines of research in order to point out the determinants of this mechanisms of injury.
- Proportion of Home and Leisure Accidents in mainland Portugal, in 2019Publication . Alves, Tatiana; Rodrigues, Emanuel; Neto, Mariana; Mexia, Ricardo; Matias-Dias, CarlosUnintentional injuries are recognized by the World Health Organization and the European Union as a preventable public health problem contributing to mortality and morbidity burden and expression in the emergency department (ED). According to EuroSafe injury is the fourth most common cause of death within the EU, being the leading cause of death in the youngest. Whereas injury related fatalities is only a part of the problem and more patients require hospital treatment it is essential measure the size of the injury problem and characteristics of these non-fatal injuries. Information from Injury Data-Base reveals that the majority of injury related ED attendances and hospital admissions result from accidents occur in home and during leisure times. So, the aim of this study it was to know the proportion of Home and Leisure Accidents (HLA) which needed attendance in the emergency rooms of the Hospitals National Health, in Portugal Mailand, in 2019. For the analysis were considered the total number of NHS health entities that have an ED, SONHO information system and National injury surveillance system - EVITA System. Based on hospital emergency records in 2019, was obtained the total number of victims by HLA who needed assistance in this health services. In 2019, there were 526 786 ED attendances due to HLA, so about 11,3% of hospital ED attendances in mainland Portugal were caused by HLA. Globally, it was observed a proportion of HLA with admission in ED higher in males (12,9%) than females (10,1%). Disaggregating the data by age group, it was possible to observe a preponderance of males in victims aged less than or equal to 54 years. On the other hand, females showed a higher proportion in individuals aged 55 and over. Additionally, victims aged 75 and over had the highest proportion of hospital admissions by HLA, both in females (15,5%) and males (13,1%). This study represented a relevant advance contributing to the revelation of the dimension of this problem in Portugal.
- Optimization of Extraction Conditions for Gracilaria gracilis Extracts and Their Antioxidative Stability as Part of Microfiber Food Coating AdditivesPublication . Reboleira, João; Ganhão, Rui; Mendes, Susana; Adão, Pedro; Andrade, Mariana; Vilarinho, Fernanda; Sanches-Silva, Ana; Sousa, Dora; Mateus, Artur; Bernardino, SusanaIncorporation of antioxidant agents in edible films and packages often relies in the usage of essential oils and other concentrated hydrophobic liquids, with reliable increases in antimicrobial and antioxidant activities of the overall composite, but with less desirable synthetic sources and extraction methods. Hydroethanolic extracts of commercially-available red macroalgae Gracilaria gracilis were evaluated for their antioxidant potential and phenolic content, as part of the selection of algal biomass for the enrichment of thermoplastic film coatings. The extracts were obtained through use of solid-liquid extractions, over which yield, DPPH radical reduction capacity, total phenolic content, and FRAP activity assays were measured. Solid-to-liquid ratio, extraction time, and ethanol percentages were selected as independent variables, and response surface methodology (RSM) was then used to estimate the effect of each extraction condition on the tested bioactivities. These extracts were electrospun into polypropylene films and the antioxidant activity of these coatings was measured. Similar bioactivities were measured for both 100% ethanolic and aqueous extracts, revealing high viability in the application of both for antioxidant coating purposes, though activity losses as a result of the electrospinning process were above 60% in all cases.
