- Classifying Functioning of Children and Adolescents with Intellectual Disability: The Utility of the International Classification of Functioning, Disability and Health for Children and YouthPublication . Vale, Maria do Carmo; Pereira-da-Silva, Luis; Pimentel, Maria João; Marques, Teresa Nunes; Rodrigues, Helena; Cunha, Gilda; Machado, Maria do Céu; Sanches-Ferreira, Manuela; Simeonsson, Rune J.Observational cross-sectional study carried out in a pediatric neurodevelopment unit of a tertiary-care hospital. A sample of 355 children with median ((min.–max.) 1.0–17.3) years with intellectual disability (30.4% borderline, 43.1% mild, 19.7% moderate, 5.1% severe, and 1.7% profound disability) was seen over a period of 3 years. Based on clinical observation and psychological evaluation, a neurodevelopmental pediatrician selected ICF-CY body functions codes, and respective qualifiers, to effectively describe functioning of children. Based on evaluation reports, a psychologist and a special educator assigned the previously chosen ICF-CY body functions codes to 139 and 67 children, respectively. Inter-rater agreement was estimated using simple and weighted Cohen’s kappa coefficients and Gwet’s AC1 statistic and Gwet’s weighted kappa coefficient statistic. A set of eight ICF-CY codes was identified as efficiently describing impairments of body functions of children with intellectual disability: global mental functions b117 and b122; specific mental functions b147, b163, b164, and b167; and voice and speech functions b320 and b330. Results indicate a correspondence between the level of severity of qualifiers assigned to ICF-CY codes and the level of intellectual disability. Inter-rater agreement was variable among raters, with the best agreements found for qualifying intellectual functions (b117) and psychomotor functions (b122). A profile of eight ICF-CY codes effectively describes functioning of children with intellectual disability, providing an alternative to medically based classification, based on diagnoses with functionally based classification of children’s characteristics. The findings contribute to define a comprehensive set of codes to reliably record individual differences of functioning in this population
- Evaluation of the Biological Potential of Himanthalia elongata (L.) S.F.Gray and Eisenia bicyclis (Kjellman) Setchell Subcritical Water ExtractsPublication . Gomes, Inês; Rodrigues, Helena; Rodrigues, Carla; Oliveira, Marta Marques; Paíga, Paula; Paiva, Alexandre; Simões, Pedro; Fernandes, Virgínia Cruz; Vieira, Mónica; Delerue-Matos, Cristina; Soares, Cristina; Grosso, ClaraNeuroprotection is a need that remains unmet in treating chronic neurodegenerative disorders, despite decades of extensive research. To find new neuroprotective compounds, extracts of Himanthalia elongata (L.) S.F.Gray and of Eisenia bicyclis (Kjellman) Setchell were obtained through subcritical water extraction applying a four-step temperature gradient. The fractions obtained were screened against brain enzymes involved in neurodegenerative etiology, namely in Alzheimer’s and Parkinson’s diseases, and against reactive oxygen and nitrogen species, all contributing factors to the progression of neurodegeneration. Results showed no significant enzyme inhibition but strong radical scavenging activities, particularly in the fourth fraction, extracted at the highest temperature (250 °C), highlighting their ability to retard oxidative and nitrosative stresses. At higher temperatures, fractions were composed of phenolic compounds and Maillard reaction products, a combination that contributed to their antioxidant activity and, consequently, their neuroprotective properties. All fractions were evaluated for the presence of iodine, 14 organochlorine and 7 organophosphorus pesticides, and pharmaceuticals used in Alzheimer’s and Parkinson’s diseases (14), psychiatric drugs (8), and metabolites (8). The fractions studied did not present any of the screened contaminants, and only fraction 1 of E. bicyclis should be used with caution due to iodine content.

- Looking at music, science and education through the pianoscopePublication . Rodrigues, Paulo Maria; Lopes, Filipe; Miguel, Mariana; Rodrigues, HelenaOver the last few years Companhia de Música Teatral (CMT) has been developing a series of original ideas that has designated as “artistic-educative constellations”. CMT's work is deeply rooted in music but explores links with other artistic languages and technology and proposes an intrinsic articulation with education (in a very broad sense). The CMT projects are a kaleidoscope of Performance pieces, Installations, Workshops, Publications and TransFormation activities and the piano has been central to many of these projects. One constellation in particular, Anatomia do Piano, has made the piano the “attractor” of a series of initiatives that connect the “main-stage” with the classroom, the science laboratory or the community. The installation Pianoscópio, part of this constellation, is the subject of this communication: it is based on the idea of “deconstructing” the piano, in order to contribute to a more profound understanding of music, creating an opportunity for discovery and expression. It is an experience that transforms the piano into a collective instrument, a sound installation/sculpture capable of producing sounds of a myriad of colours, a space to be inhabited by people and produce sound through their combined interaction. In this paper we report on the experience using the Pianoscópio in a wide range of situations, from workshops with children to concerts and recordings with professional musicians, science-based projects or projects with the community.
