    Brain energy rescue:an emerging therapeutic concept for neurodegenerative disorders of ageing

    Get PDF
    The brain requires a continuous supply of energy in the form of ATP, most of which is produced from glucose by oxidative phosphorylation in mitochondria, complemented by aerobic glycolysis in the cytoplasm. When glucose levels are limited, ketone bodies generated in the liver and lactate derived from exercising skeletal muscle can also become important energy substrates for the brain. In neurodegenerative disorders of ageing, brain glucose metabolism deteriorates in a progressive, region-specific and disease-specific manner — a problem that is best characterized in Alzheimer disease, where it begins presymptomatically. This Review discusses the status and prospects of therapeutic strategies for countering neurodegenerative disorders of ageing by improving, preserving or rescuing brain energetics. The approaches described include restoring oxidative phosphorylation and glycolysis, increasing insulin sensitivity, correcting mitochondrial dysfunction, ketone-based interventions, acting via hormones that modulate cerebral energetics, RNA therapeutics and complementary multimodal lifestyle changes

    A obtenção de resultados cada vez melhores no tratamento do câncer colorretal apresenta-se hoje como um desafio devido à sua crescente prevalência em todo o mundo. Diversos estudos têm demonstrado que a qualidade do tratamento cirúrgico instituído representa um dos principais fatores prognósticos, podendo ser esta avaliada através de aspectos como mortalidade operatória, preservação esfincteriana, recorrência local e sobrevida. O objetivo do presente trabalho é apresentar os resultados obtidos a longo prazo no tratamento cirúrgico do câncer colorretal pelo Grupo de Coloproctologia do Departamento de Cirurgia do Hospital Municipal São José, em Joinville, e confrontá-los com a literatura a respeito, visando obter uma avaliação crítica da qualidade do tratamento instituído. Foi realizada uma análise prospectiva de uma série consecutiva de 97 pacientes submetidos ao tratamento cirúrgico do câncer colorretal, com perspectivas curativas e tempo de seguimento médio de 80,8 meses. Foi observada mortalidade operatória em seis pacientes (6,1%), recidiva local para câncer retal e colônico em seis (12,5%) e quatro (9,7%) pacientes, respectivamente, e a necessidade de realização de colostomia definitiva no câncer retal em 14 casos (27%). A sobrevida geral média foi de 48,9 meses. A sobrevida geral de cinco anos para o seguimento oncológico (n=63) foi de 52%, sendo 89% para pacientes estágio 1, 70% para pacientes estágio 2 e 20% para pacientes estágio 3. Concluímos que o tratamento instituído encontra-se dentro dos padrões aceitáveis do ponto de vista da literatura, demonstrando, no entanto, a necessidade de aprimoramento em alguns aspectos específicos.<br>Improvement of results in treatment of colorectal cancer remains a major challenge due to its increasing worldwide prevalence. Several studies have demonstrated the quality of surgical treatment as one of the most important prognostic factors, assessed by parameters such as operative mortality, sphincter preservation, local recurrence and survival rates. The aim of this study is to present the long term results of Coloproctology Group of Department of Surgery of Hospital Municipal São José, in Joinville, Brazil, as well as its quality analysis according to the accepted standards from literature. A prospective analysis of a consecutive series of 97 colorectal cancer patients operated for curative purpose was undertaken, with a mean follow up of 80,8 months. Operative mortality occurred in six patients (6,1%), local recurrence for recatl and colon cancer in six (12,5%) and four (9,7%) patients, respectively, and abdominoperineal resection was performed in 14 cases (27%) for rectal cancer. Mean overall survival was 48,9 months. Five-year overall oncological survival (n=63) was 52%, including 89% for stage1, 70% for stage 2 and 20% for stage 3 patients. We conclude that the results obtained are acceptable for literature standards, but some specific parameters need to be improved

    A postura de atletas de ginástica rítmica: análise através da fotometria

    No full text
    A postura apresenta relação com o tipo de modalidade esportiva praticada, acompanhada de características próprias. Por isso, este trabalho teve como objetivo verificar a postura e suas possíveis alterações em atletas de ginástica rítmica. Trata-se de um estudo de fotometria - fotografias retiradas de pontos específicos demarcados no corpo da atleta, sendo analisados pelo software de avaliação postural (SAPO). Participaram do estudo 27 indivíduos do sexo feminino, entre sete e 15 anos, atletas de uma equipe GR de Maringá, PR. Foram verificadas alterações em todas as atletas, sendo que algumas mostraram-se maiores, que podem ser justificadas pelos aspectos característicos da modalidade, e necessitam de novas análises. Portanto, a avaliação postural das atletas de GR torna-se importante como medida profilática para identificar os possíveis desalinhamentos posturais

    Conflict of interest policies and disclosures requirements among European society of cardiology national cardiovascular journals

    Disclosure of potential conflicts of interest (COI) is used by biomedical journals to guarantee credibility and transparency of the scientific process. COI disclosure, however, is not systematically nor consistently dealt with by journals. Recent joint editorial efforts paved the way towards the implementation of uniform vehicles for COI disclosure. This paper provides a comprehensive editorial perspective on classical COI-related issues. New insights into current COI policies and practices among European Society of Cardiology national cardiovascular journals, as derived from a cross-sectional survey using a standardised questionnaire, are discussed
