RESUMO
Aims: To describe the characteristics of the most accessed YouTube videos in Brazilian-Portuguese on cerebral palsy (CP), and to analyze content of informational videos about this topic.Methods: This was a cross-sectional study. Searching on YouTube website was conducted by two independent examiners between November and December 2019, using the keywords "Paralisia Cerebral" sorted by videos' number of views. Videos that did not present content related to CP or duplicate videos were excluded. The interaction parameters and content characteristics of the included videos were extracted. To access the trustworthiness and quality of informational videos, the modified Discern checklist and the Global Quality Score was used.Results: Following the eligibility criteria 90 videos were included. Fifty-three (53) were classified as experiential videos and 37 as informational videos. Informational videos presented multi-topics about different aspects of CP. This group of videos presented moderate trustworthiness due to the lack of scientific evidence content. Informational videos had good quality and generally good flow.Conclusion: YouTube presented a large number of videos about CP in Brazilian-Portuguese. Informational videos are useful for patients and healthcare providers; however, it is necessary to included information about scientific evidence, as a strategy to facilitate and promote knowledge translation.

OBJETIVO: Identificar e avaliar os estudos publicados sobre fisioterapia em crianças e adolescentes brasileiros com paralisia cerebral (PC), usando o modelo da Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF). MÉTODO: Artigos em inglês e português publicados até outubro de 2020, sem restrição de data, foram pesquisados em diferentes bases bibliográficas. Foram extraídos dados sobre as características do estudo, métricas do periódico, características da amostra, domínios da CIF explorados a partir dos componentes e desfechos das intervenções. Para caracterizar as evidências, os estudos foram classificados de acordo com os níveis de evidência do Centro de Medicina Baseada em Evidência de Oxford. RESULTADOS: Noventa e quatro estudos foram incluídos. Crianças com PC espástica e com menores limitações nas habilidades motoras grossas foram as mais reportadas; 67% dos estudos apresentaram baixos níveis de evidência e foram publicados em periódicos sem fator de impacto. As três intervenções mais frequentes foram o conceito neuroevolutivo Bobath/terapia do neurodesenvolvimento, a terapia com vestes e a estimulação transcraniana por corrente contínua. Os componentes das intervenções exploraram estruturas e funções do corpo (73,4%), atividade (59,6%) e ambiente (2,1%). Entretanto não exploraram a participação (0%). Os desfechos investigados abordaram atividade (79,8%), estruturas e funções do corpo (67,0%), participação (1%) e ambiente (0%). INTERPRETAÇÃO: Os estudos de intervenções fisioterapêuticas para crianças e adolescentes brasileiros com PC, apresentam maior foco em minimizar deficiências em estruturas e funções do corpo e limitações de atividades. São necessários mais estudos, com melhor nível de evidência e foco ampliado para a participação e os fatores ambientais.
RESUMO
AIM: To identify and assess published studies concerning physical therapy in Brazilian children and adolescents with cerebral palsy (CP) using the International Classification of Functioning, Disability and Health (ICF) framework. METHOD: Articles in English and Portuguese published until October 2020, with no date restrictions, were searched in several different databases. Study characteristics, journal metrics, sample characteristics, and ICF domains explored intervention components and outcomes were extracted. Studies were classified according to the Oxford Centre for Evidence-Based Medicine hierarchy levels to characterize the evidence. RESULTS: Ninety-four studies were included. Spastic CP with fewer limitations in gross motor abilities was the most reported; 67% of the studies had low levels of evidence and were published in journals without an impact factor. The three most frequent interventions were neurodevelopmental treatment, suit therapy, and transcranial direct current stimulation. Intervention components explored body functions and structures (73.4%), activity (59.6%), environment (2.1%). They did not explore participation (0%). The outcomes investigated addressed activity (79.8%), body functions and structures (67.0%), and participation (1.1%), but not environment (0%). INTERPRETATION: Studies of physical therapy for Brazilian children and adolescents with CP focused on reducing impairments and activity limitations. Studies with higher levels of evidence and an expanded focus on participation and environmental factors are necessary.

Ursolic acid (UA) and oleanolic acid (OA) are pentacyclic triterpenoid compounds found in plants used in the human diet and in medicinal herbs, in the form of aglycones or as the free acid. These compounds are known for their hepatoprotective, anti-inflammatory, antimicrobial, hypoglycemic, antimutagenic, antioxidant, and antifertility activities. In the present study, we evaluated the effects of UA and OA on the formation of 1,2-dimethyl-hydrazine (DMH)-induced aberrant crypt foci (ACF) in the colon of the male Wistar rat. The animals received subcutaneous (sc) injections of DMH (40 mg/kg body weight) twice a week for two weeks to induce ACF. UA, OA and a mixture of UA and OA were administered to the rats five times a week for four weeks by gavage at doses of 25 mg/kg body weight/day each, during and after DMH treatment. All animals were sacrificed in week 5 for the evaluation of ACF. The results showed a significant reduction in the frequency of ACF in the group treated with the triterpenoid compounds plus DMH when compared to those treated with DMH alone, suggesting that UA and OA suppress the formation of ACF and have a protective effect against colon carcinogenesis.
