- ItemSomente MetadadadosAcute personalized habitual caffeine doses improve attention and have selective effects when considering the fractionation of executive functions(Wiley-blackwell, 2016) Lanini, Juliana [UNIFESP]; Fernandes Galduroz, Jose Carlos [UNIFESP]; Pompeia, Sabine [UNIFESP]Caffeine is widely used, often consumed with food, and improves simple and complex/executive attention under fasting conditions. We investigated whether these cognitive effects are observed when personalized habitual doses of caffeine are ingested by caffeine consumers, whether they are influenced by nutriments and if various executive domains are susceptible to improvement. This was a double-blind, placebo-controlled study including 60 young, healthy, rested males randomly assigned to one of four treatments: placebo fasting, caffeine fasting, placebo meal and caffeine meal. Caffeine doses were individualized for each participant based on their self-reported caffeine consumption at the time of testing (morning). The test battery included measures of simple and sustained attention, executive domains (inhibiting, updating, shifting, dual tasking, planning and accessing long-term memory), control measures of subjective alterations, glucose and insulin levels, skin conductance, heart rate and pupil dilation. Regardless of meal intake, acute habitual doses of caffeine decreased fatigue, and improved simple and sustained attention and executive updating. This executive effect was not secondary to the habitual weekly dose consumed, changes in simple and sustained attention, mood, meal ingestion and increases in cognitive effort. We conclude that the morning caffeine "fix" has positive attentional effects and selectively improved executive updating whether or not caffeine is consumed with food.

- ItemSomente MetadadadosAvaliação Cognitiva Dinâmica de Terapia Ocupacional para crianças (DOTCA-Ch): perfil de desempenho cognitivo de crianças de 06 a 12 anos na rede municipal de ensino de Santos(Universidade Federal de São Paulo (UNIFESP), 2019-02-01) Demarchi, Gabriela Souza Dos Santos [UNIFESP]; Novelli, Marcia Maria Pires Camargo [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Introduction: The Dynamic Occupational Therapy Cognitive Assessment for Children (DOTCA-Ch) was constructed with the proposal to evaluate the cognitive performance of children aged 6 to 12 years in 22 subtests distributed in five cognitive areas: Orientation, Space Perception, Praxis, Visuomotor Construction and Thought Operations. For each subtest, there is a structured choice of five levels of mediation. Objective: Describe the cognitive performance profile in children of the municipal teaching system of Santos from the applications of the Portuguese version of the DOTCA-Ch battery. Method: The study was carried out in partnership with the Secretary of Education of the municipal of Santos, in five schools municipal, with 169 children of both sexes, distributed between the 1st and 7th year, evaluations were carried out in the period from August 2015 to November 2018. The children were grouped into four age groups, and descriptive analyzes of the scores in the cognitive and subtest areas, as well as the use of mediations, comparing the data with original study. conducted in Israel. Results: The children in the sample are gender-equitative; in the cognitive areas, our children excelled in Praxis and Thought Operations performances compared to the original study conducted in Israel, and mediations present themselves as a potentiator for improved performance in all areas and groups. Conclusion: From the battery, DOTCA-Ch presents the first profile of cognitive performance related to santista children, being a dynamic instrument that identifies the potentialities and limitations of children in a playful way.
- ItemAcesso aberto (Open Access)Desempenho neurocognitivo de pacientes com malformação arteriovenosa cerebral(Universidade Federal de São Paulo (UNIFESP), 2019-07-25) Coelho, Daniela De Souza [UNIFESP]; Chaddad Neto, Feres Eduardo Aparecido [UNIFESP]; Santos, Flávia Heloísa dos; http://lattes.cnpq.br/5842894807452055; http://lattes.cnpq.br/9356651929657562; http://lattes.cnpq.br/3251530625558141; Universidade Federal de São Paulo (UNIFESP)Cerebral arteriovenous malformation (cAVM) is a relatively rare congenital disease that usually occurs in the third to fourth decade of life. Its symptoms vary according to its ruptured and unruptured presentation, however, neurocognitive aspects are not usually addressed in the list of neurological symptoms. Objective: To describe the neurocognitive functions of patients with ruptured and unruptured MAVcs according to the Spetzler-Martin (SM) scale, flow status and anatomical topography. Method: In this partially blind cross-sectional study, 91 patients with cAVM of both genders, aged between 18 and 60 years, were approached. Seventy patients who met the criteria for inclusion in the study were selected for evaluation, and these were evaluated using the Neupsilin Brief Neuropsychological Instrument. Results: Out of 70 patients, 50 (71.43%) with MAVc presented deficits in at least one of the 8 neurocognitive domains surveyed, although they did not present neurological deficits. Of these MAVcs, 50% were unruptured, and no significant difference in memory was observed compared with the group of patients with a MAVc rupture in the temporal lobe. The Spetzler-Martin scale did not influence the results of patients with an unruptured MAVc. We found deficits in working memory in patients with ruptured MAVcs high-grade (SM), and we found deficits in executive function (verbal fluency) in patients with low-grade (SM) MAVcs (p < 0.001). Conclusion: The cAVM patients unruptured e ruptured even without neurological symptoms, already present neurocognitive deficits. The scales that evaluate disability used in the main clinical studies do not evaluate neurocognitive alterations and thus disregard any deficits that affect quality of life. This finding raises an important question about the effects of interventional treatment because it reinforces the hypothesis that cognitive alterations may be pre-existing and not determined by the interventions.
- ItemEmbargoEvidências de Validade Externa (Validade de Critério) da Avaliação Cognitiva Dinâmica de Terapia Ocupacional de Loewenstein - versão geriátrica (DLOTCA-G) em uma população de pessoas idosas sem alterações cognitivas(Universidade Federal de São Paulo, 2023-12-11) Batista, Isabel Francielle Veloso [UNIFESP]; Novelli, Marcia Maria Pires Camargo [UNIFESP]; http://lattes.cnpq.br/0472842252184977; http://lattes.cnpq.br/2104853071423907; Universidade Federal de São Paulo (UNIFESP)Evidências de Validade Externa (Validade de Critério) da Avaliação Cognitiva Dinâmica de Terapia Ocupacional de Loewenstein - versão geriátrica (DLOTCA-G) em uma população de pessoas idosas sem alterações cognitivas Introdução: A bateria de Avaliação Cognitiva Dinâmica de Terapia Ocupacional de Loewestein - versão geriátrica (DLOTCA-G) é um instrumento de avaliação cognitiva específico da área da Terapia Ocupacional (TO) que avalia 8 domínios: orientação, consciência, percepção visual e espacial, práxis, construção visuomotora, operações de pensamentos e memória. Objetivos: Avaliar a aplicabilidade da bateria DLOTCA-G em uma amostra de pessoas idosas sem alterações cognitivas. Materiais e Métodos: A bateria foi aplicada em uma amostra de pessoas idosas. Os participantes foram avaliados utilizando os seguintes instrumentos: questionário sociodemográfico, Exame Cognitivo de Addenbrooke Revisado (ACE-R) e a bateria DLOTCA-G. Para a análise da aplicabilidade foi feita a análise dos desempenhos nos domínios e do uso das mediações descritas em médias, desvios-padrões e porcentagens, e para a avaliação da evidência de validade de critério a pontuação total da DLOTCA-G e do ACE=R foram correlacionadas e foi utilizado o coeficiente de correlação de Pearson. Resultados: Foram avaliadas 20 pessoas idosas, sendo 15 mulheres (75%) e 5 homens (25%). A média de idade foi de 71,95 (± 5,76) anos e a média de escolaridade foi de 13,25 (± 5,29) anos. A pontuação média total obtida no ACE-R foi de 86,45 (± 10,04) pontos e no DLOTCA-G foi de 24,38 (± 1,26) pontos. Acerca do tempo de aplicação, 90% dos participantes conseguiram concluir a bateria em uma sessão. Com relação ao desempenho dos domínios cognitivos, as pessoas idosas apresentaram mais dificuldades nos testes de Práxis, Construção Visuomotora e Operações de Pensamento e sobre o uso das mediações, as mais utilizadas foram as que alocam recursos atencionais das pessoas idosas. Na análise de validade de critério o coeficiente de correlação de Pearson foi de r=0,55. Conclusão: A bateria parece ter uma acurácia para avaliar o desempenho das pessoas idosas, onde elas apresentaram mais dificuldades nos domínios de Práxis, Construção Visuomotora e Operações de Pensamento, no entanto, para a amostra avaliada, não apresentou bons resultados de correlação com o ACE-R.
