Impact of cerebrovascular risk factors over the evolution of dementia due to Alzheimer's disease in a sample of patients with low schooling from Sao Paulo, Brazil

The objective of this paper is to evaluate the impact of cerebrovascular risk factors over the rate of progression of Alzheimer's disease in a sample of patients with low schooling. Lower schooling, but not cerebrovascular risk, had a significant effect for a faster rate of progression of Alzheimer's disease, assessed by way of MMSE and CDR scores.Fed Univ Sao Paulo UNIFESP, Escola Paulista Med, Sao Paulo, BrazilFed Univ Sao Paulo UNIFESP, Escola Paulista Med, Sao Paulo, BrazilWeb of Scienc

Epidemiology of dementia in Sao Paulo, Brazil: risk factors and age of onset of dementia due to Alzheimer's disease

The objective of this paper is to investigate the impact of previously reported sporadic risk factors over the age of onset of Alzheimer's disease in a Brazilian sample. The survey included 129 patients with late-onset Alzheimer's disease, assessed for gender, schooling, cerebrovascular risk, history of brain trauma with loss of consciousness, systemic infections, and family history of Alzheimer's disease, neurological disorders other than Alzheimer's disease, brain diseases in general, or cardiovascular diseases. We concluded that environmental, educational and demographic factors did not seem to be significantly related to the age of onset of Alzheimer's disease on this sample.Fed Univ Sao Paulo UNIFESP, Escola Paulista Med, Sao Paulo, BrazilFed Univ Sao Paulo UNIFESP, Escola Paulista Med, Sao Paulo, BrazilWeb of Scienc

Sleep in the neuropsychiatric evaluation of patients with dementia due to Alzheimer's disease

The objective of this paper is to evaluate the amount of sleep of patients with Alzheimer's disease, as well as which factors might influence their sleep patterns. After the assessment of 131 patients with dementia due to Alzheimer's disease, we concluded that low schooling impacts the evolution of these patients as much as their sleep patterns, which are likewise affected by neuropsychiatric symptoms. Also, satisfactory sleep seems to be related to its length for such patients.Fed Univ Sao Paulo UNIFESP, Escola Paulista Med, Sao Paulo, BrazilFed Univ Sao Paulo UNIFESP, Escola Paulista Med, Sao Paulo, BrazilWeb of Scienc

Effects of intellectual habits, leisure and physical activity over the age of onset and evolution of dementia due to Alzheimer's disease

The objective of this paper is to investigate whether intellectual, physical or leisure activities have an impact over age of onset or progression of Alzheimer's disease. We concluded that subjects who were concurrently engaged in various intellectual, physical and leisure activities earlier during their lives were less likely to develop dementia due to Alzheimer's disease before turning 80 years-old.Fed Univ Sao Paulo UNIFESP, Escola Paulista Med, Sao Paulo, BrazilFed Univ Sao Paulo UNIFESP, Escola Paulista Med, Sao Paulo, BrazilWeb of Scienc

Aprendizado de máquina e análise de sentimentos para avaliar a evolução da pandemia de COVID-19 e os impactos no turismo

This article aims to analyze how the emotional, mental, and sentimental demands related with hospitality and hostility were developed during the pandemic of the COVID-19 in Brazil. As methological procedures was applied sequential mixed methods research. Firstly, about 1,000 pieces of news were collected from two Brazilian websites to be able to manually classify them in the feelings of hospitality and hostility. We use a machine learning supervisor analysis following a sentiment analysis technique. Secondly, the data were used for training in eight machine learning algorithms, through supervised analysis, being chosen the logistic regression for the data classification, because it fits better to the data, reaching 72% of accuracy. The data collected in two years of the pandemic, thus approximately 221,000 news were then classified using the chosen algorithm, which allowed the generation of graphics and analysis through inferential statistics, through the evolution of feelings of hospitality and hostility. The results indicate that in situations such as the COVID-19 pandemic, people tend to behave hostilely, which leads to a lack of hospitality. The implications of this study are related to the ability to materialize, through the concepts of hospitality and hostility, the perception of visitors, guests, among other people, involved in the tourism sector. Therefore, the sentiment analysis from social media and news affected the tourism and hospitality industry.Cet article vise à analyser comment les demandes émotionnelles, mentales et sentimentales liées à l'hospitalité et à l'hostilité se sont développées pendant la pandémie de la COVID-19 au Brésil. Des procédures méthodologiques ont été appliquées à travers une recherche séquentielle à méthodes mixtes. Tout d'abord, environ 1 000 articles ont été collectés sur deux sites web brésiliens pour être classifiés manuellement selon les sentiments d'hospitalité et d'hostilité. Nous avons utilisé une analyse de sentiment supervisée par apprentissage automatique. Ensuite, les données ont été utilisées pour entraîner huit algorithmes d'apprentissage automatique, à travers une analyse supervisée, la régression logistique ayant été choisie pour la classification des données, car elle correspond mieux aux données, atteignant 72% de précision. Les données collectées sur deux ans de pandémie, soit environ 221 000 articles, ont ensuite été classées en utilisant l'algorithme choisi, ce qui a permis de générer des graphiques et des analyses à l'aide de statistiques inférentielles, montrant l'évolution des sentiments d'hospitalité et d'hostilité. Les résultats indiquent que dans des situations telles que la pandémie de la COVID-19, les gens ont tendance à adopter un comportement hostile, ce qui conduit à un manque d'hospitalité. Les implications de cette étude sont liées à la capacité de matérialiser, à travers les concepts d'hospitalité et d'hostilité, la perception des visiteurs, des clients et d'autres personnes impliquées dans le secteur du tourisme. Ainsi, l'analyse de sentiments à partir des médias sociaux et des actualités a affecté l'industrie du tourisme et de l'hospitalité.Este artigo tem como objetivo analisar como as demandas emocionais, mentais e sentimentais relacionadas à hospitalidade e hostilidade se desenvolveram durante a pandemia de COVID-19 no Brasil.

A Ampliação da Jurisdição Internacional: o surgimento de uma jurisdição internacional em matéria penal

: O presente artigo se propõe a analisar a ampliação da jurisdição internacional, fenômeno que caracteriza as relações jurídicas internacionais ao longo do século XX, com o crescimento da competência material da jurisdição das cortes internacionais. Num ambiente desprovido de uma autoridade hierarquicamente superior e centralizada, a atividade dos tribunais vem preencher uma lacuna que contribui para o desenvolvimento progressivo do Direito Internacional. O surgimento das cortes internacionais foi marcado por uma concepção voluntarista de direito internacional: os tribunais deveriam ter jurisdição deferente à soberania dos Estados. Porém, depois da Segunda Guerra Mundial, um novo modelo de justiça internacional tem gradativamente erodido esta estrutura tradicional clássica, e a Corte Internacional de Justiça passa a ter um papel mais ativo do que a sua predecessora. O nascimento de uma jurisidição penal internacional emerge nesse novo cenário e consagra a responsabilidade penal individual – o que supera a regra tradicional de que apenas os Estados seriam passíveis de responsabilidade internacional. Conclui-se que a a justiça penal internacional integra este movimento de expansão da jurisdição internaciona
