    Objective: To conduct a pilot randomized control trial to assess the feasibility and acceptability of full-body interaction cognitive training (FBI-CT) inspired by instrumental activities of daily living in chronic psychiatric inpatients and to explore its preliminary impact on cognitive and noncognitive outcomes. Materials and Methods: Twenty psychiatric inpatients met the inclusion criteria and were randomly allocated to the FBI-CT group (n = 10) or the tablet-based CT group (T-CT) (n = 10). Neuropsychological assessments were performed at baseline, postintervention, and 3-month follow-up. Results: Both groups presented high completion rates at postintervention and follow-up. Participants reported high satisfaction following the interventions, with the FBI-CT group exhibiting slightly higher satisfaction. A within-group analysis showed significant improvements in the FBI-CT group for processing speed and sustained attention for short periods (P = 0.012), verbal memory (P = 0.008), semantic fluency (P = 0.027), depressive symptoms (P = 0.008), and quality of life (P = 0.008) at postintervention. At 3-month follow-up, this group maintained verbal memory improvements (P = 0.047) and depressive symptoms amelioration (P = 0.026). The T-CT group revealed significant improvements in sustained attention for long periods (P = 0.020), verbal memory (P = 0.014), and executive functions (P = 0.047) postintervention. A between-group analysis demon strated that the FBI-CT group exhibited greater improvements in depressive symptoms (P = 0.042). Conclusions: Overall, we found support for the feasibility and acceptability of both training approaches. Our findings show promise regarding the preliminary impact of the FBI-CT intervention, but due to study limitations such as the small sample size, we cannot conclude that FBI-CT is a more effective approach than T-CT for enhancing cognitive and noncognitive outcomes of chronic psychiatric inpatients.

    Background: Different intervention strategies, such as reminiscence and music-based therapies, effectively mitigate the cognitive decline of individuals with dementia (IwD). An important challenge when implementing these approaches lies in the need for content customization. We de signed Musiquence platform, a framework that allows the customization of music and reminiscence content in cognitive stimulation activities. (2) Methods: Here, we present a participatory design methodology for designing a seven-week customized cognitive stimulation program (CCSP) for IwD using Musiquence. We ran focus groups with 19 formal caregivers, who provided information regarding themes and music to be used in activities for IwD, and gathered preferences from 20 IwD. (3) Results: The CCSP consists of seven cycles of tasks combining the activities available in Musiquence, the seven preferential themes of IwD, and the seven songs most frequently referenced by formal caregivers. (4) Conclusions: Finally, we provide a set of guidelines to implement a participatory design approach for content development together with IwD.info:eu-repo/semantics/publishedVersio

    Efficacy of adaptive cognitive training through desktop virtual reality and paper-and-pencil in the treatment of mental and behavioral disorders

    Cognitive defcits are a core feature of mental and behavioral disorders, leading to poor treatment adherence and functional ity. Virtual reality (VR) methodologies are promising solutions for cognitive interventions in psychiatry once they provide greater ecological validity. This study assessed and compared two content-equivalent cognitive training (CT) interventions, delivered in desktop VR (Reh@City v2.0) and paper-and-pencil (Task Generator (TG)) formats, in patients with mental and behavioral disorders. 30 patients were randomly assigned to the Reh@City v2.0 group and the TG group. Both groups of patients underwent a time-matched 24-sessions intervention. Neuropsychological assessments were performed at baseline, post-intervention, and follow-up. A within-groups analysis revealed signifcant improvements in visual memory and depres sive symptomatology after the Reh@City intervention. The TG group improved in processing speed, verbal memory, and quality of life (social relationships and environmental domains). Between groups, Reh@City led to a greater reduction in depressive symptomatology, whereas the TG group showed higher improvements in social relationships aspects of quality of life. At follow-up, previous gains were maintained and new improvements found in the Reh@City (global cognitive func tion, language, visuospatial and executive functions) and the TG groups (attention). The Reh@City signifcantly reduced depressive symptomatology, and the TG led to greater improvements in processing speed, abstraction, and social relationships domain of quality of life at follow-up. Both interventions were associated with important cognitive, emotional, and quality of life benefts, which were maintained after two months. Reh@City and TG should be considered as complementary CT methods for patients with mental and behavioral disorders. Trial registration The trial is registered at ClinicalTrials.gov, number NCT04291586.info:eu-repo/semantics/publishedVersio

    NeuroAIreh@b: an artificial intelligence-based methodology for personalized and adaptive neurorehabilitation

    Get PDF
    Cognitive impairments are a prevalent consequence of acquired brain injury, dementia, and age-related cognitive decline, hampering individuals' daily functioning and independence, with significant societal and economic implications. While neurorehabilitation represents a promising avenue for addressing these deficits, traditional rehabilitation approaches face notable limitations. First, they lack adaptability, offering one-size-fits-all solutions that may not effectively meet each patient's unique needs. Furthermore, the resource-intensive nature of these interventions, often confined to clinical settings, poses barriers to widespread, cost-effective, and sustained implementation, resulting in suboptimal outcomes in terms of intervention adaptability, intensity, and duration. In response to these challenges, this paper introduces NeuroAIreh@b, an innovative cognitive profiling and training methodology that uses an AI-driven framework to optimize neurorehabilitation prescription. NeuroAIreh@b effectively bridges the gap between neuropsychological assessment and computational modeling, thereby affording highly personalized and adaptive neurorehabilitation sessions. This approach also leverages virtual reality-based simulations of daily living activities to enhance ecological validity and efficacy. The feasibility of NeuroAIreh@b has already been demonstrated through a clinical study with stroke patients employing a tablet-based intervention. The NeuroAIreh@b methodology holds the potential for efficacy studies in large randomized controlled trials in the future

    Unraveling the role of TBCCD1 protein on cell size control: the regulation of cytoskeleton dynamics and cell junctions

    Get PDF
    During their lifetime most cells maintain their size. There is increasing evidence showing that this process may be dynamic and that cells can adapt their size in response to external signals and changes in the environment [1], which strongly suggests that cell size is regulated. Both Hippo and IGF/PI3K/AKT/mTORC1 pathways have been described as being involved in cell size/growth control [1]. Interestingly, these pathways are in a cross-talk with others involved and/or dependent on cellular polarity [2]. Our group characterized a centrosomal protein, TBCCD1 (TBCC domain – containing human protein 1) which, when depleted in human retinal epithelial (RPE–1) cells, leads to an abnormal localization of the centrosome at the cell periphery accompanied by the fragmentation of the Golgi apparatus, resulting in the disruption of the intrinsic cell polarity axis “Nucleus-Centrosome-Golgi Apparatus”. Moreover, TBCCD1 – depleted cells are larger, slower and have a lower efficiency in primary cilia assembly than control cells [3]. We identified the TBCCD1 interactome that showed that most of its partners are involved in cell polarity. Furthermore, most of them participate in the formation/maintenance of cell junctions, which are main regulators of cell polarity in epithelia and are upstream of pathways, like Hippo pathway. We also observed that TBCCD1 overexpression affects tubulin acetylation, which supports our results showing that some of the partners are involved in the regulation of the cytoskeleton dynamics, which may affect cell size. Therefore, it is tempting to hypothesize that the mechanisms involved in the establishment of intrinsic cell polarity may also directly/indirectly participate in the regulation of cell size.info:eu-repo/semantics/publishedVersio

    O treino cognitivo (TC) atravĂ©s das novas tecnologias representa uma estratĂ©gia de intervenção promissora na mitigação dos dĂ©fices cognitivos pĂłs-AVC. Neste estudo-piloto, avaliamos o impacto a curto prazo de um novo sistema de TC com maior validade ecolĂłgica – a plataforma NeuroAIreh@b –, numa amostra de sobreviventes de AVC na fase crĂłnica. RecrutĂĄmos dez sobreviventes de AVC que foram submetidos a uma avaliação neuropsicolĂłgica (ANP) prĂ© intervenção. Posteriormente, iniciaram uma intervenção de TC implementada via tablet, com recurso Ă  versĂŁo protĂłtipo da plataforma NeuroAIreh@b, envolvendo oito sessĂ”es de 45 minutos. Nestas sessĂ”es, realizaram quatro tipos de tarefas de TC baseadas em atividades de vida diĂĄria (AVDs) (por ex., selecionar os ingredientes corretos para fazer uma receita, pagar as compras no supermercado). Foram efetuadas ANPs pĂłs-intervenção para avaliar o impacto da intervenção a curto prazo. Uma anĂĄlise intra-grupal com o teste de Wilcoxon revelou diferenças estatisticamente significativas no Montreal Cognitive Assessment (MoCA) e na pontuação total do InventĂĄrio de Avaliação Funcional de Adultos e Idosos (IAFAI). Globalmente, o TC atravĂ©s da plataforma NeuroAIreh@b parece ser benĂ©fico na fase crĂłnica do AVC, conduzindo a ganhos na cognição geral (MoCA) e na capacidade funcional (IAFAI). Estes resultados preliminares com a versĂŁo protĂłtipo da plataforma NeuroAIreh@b sĂŁo encorajadores e sugerem a generalização dos ganhos obtidos em contexto terapĂȘutico para as AVDs.Technology-based cognitive training (CT) represents a promising intervention strategy to mitigate post-stroke cognitive deficits. In this pilot study, we sought to evaluate the short-term impact of a novel CT system with greater ecological validity – the NeuroAIreh@b platform – in a sample of chronic stroke survivors. We recruited ten stroke survivors who underwent a baseline neuropsychological assessment (NPA). Then, participants were enrolled in a tablet-based CT intervention with the prototype version of the NeuroAIreh@b platform, comprising eight 45- minutes training sessions. In these sessions, participants performed four types of CT tasks inspired by activities of daily living (ADLs) (e.g., selecting the correct ingredients for a given recipe, paying for groceries in the supermarket). Post-NPAs were conducted to evaluate the interventions’ short-term impact. A within-group analysis using the Wilcoxon test revealed statistically significant improvements in the Montreal Cognitive Assessment (MoCA) and in the Adults and Older Adults Functional Assessment Inventory (IAFAI) total score. Overall, CT with the NeuroAIreh@b platform appears to be beneficial in the chronic phase of stroke, leading to gains in general cognition (MoCA) and functional abilities (IAFAI). These preliminary findings with the prototype version of the NeuroAIreh@b platform are encouraging and suggest the generalization of training gains to ADLs.info:eu-repo/semantics/publishedVersio

    O objetivo deste trabalho foi medir o empoderamento de adolescentes trabalhadores e testar sua possível associação com a qualidade de vida. Estudo transversal realizado com 363 adolescentes trabalhadores assistidos por uma Entidade Filantrópica de Apoio ao Adolescente. A coleta de dados ocorreu por meio da aplicação de dois questionårios, sendo um utilizado para mensurar a qualidade de vida (WHOQoL-Bref) e as questÔes sobre empoderamento do Questionårio Integrado para Medir Capital Social do Banco Mundial (QIMCS). A variåvel dependente (empoderamento) foi construída pelo agrupamento dos participantes, por meio da anålise de segmentação. O teste Kruskal-Wallis foi utilizado para a comparação dos escores dos domínios do WHOQoL-Bref (físico, psicológico, relaçÔes sociais e meio ambiente) entre os clusters, com 5% de significùncia. Em relação à anålise de segmentação, 126 (34,7%) adolescentes foram classificados como de baixo empoderamento, 161 (44,4%) formaram o grupo moderado e 70 (19,3%) possuíam maior empoderamento. O cluster com alto empoderamento apresentou as maiores médias dos escores de qualidade de vida em todos os domínios. O teste Kruskal-Wallis revelou diferenças estaticamente significantes entre os clusters para os domínios psicológico (p=0,001), relaçÔes sociais (p=0,003) e global (p=0,024). Concluiu-se que melhores escores de qualidade de vida foram encontrados no grupo de adolescentes com maior empoderamento

    CatĂĄlogo TaxonĂŽmico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil

    The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the CatĂĄlogo TaxonĂŽmico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others
