Estudo comparativo da expressão imuno-histoquímica do ki-67 em carcinoma epidermóide de língua em pacientes jovens e idosos

The squamous cell carcinoma (SCC) is the most common malignant neoplasm of epithelial origin in oral cavity and present high capacity to invade adjacent structures. Traditionally, SCC has a predominance of 50 years male patients with long-time use of tobacco and alcohol, and the tongue is the most affected anatomic site. At present, there is an increasing incidence of SCC in patients below 40 years of age, who has been exposed or not to risk factors, mainly for tongue lesions. This study aims to analyze cell proliferation index using Ki-67 antigen in SCC of the tongue for two groups of different age range: until 40 years and older than 50 years. The first group was composed by 16 patients and the second one was composed by 20 patients. Clinicopathological features of the cases were also assessed. There was a male predominance in both groups. Tobacco and alcohol habits were common for patients until 40 years (72,2%), as well as for patients older than 50 years (52,9%). The first group had statistical association with the presence of regional metastases (p = 0,036) and with the most advanced stages of the disease (p = 0,012). Considering the histological malignancy grading, there was higher incidence (56,2%) of high malignancy grade tumors in the group of patients until 40 years old, but no statistical difference has found between groups and histologic malignancy grading. Regarding the immunohistochemical expression of Ki-67, there was no statistically significant difference between the antibody expression of the groups, as well as between other clinical and histopathological parameters. This study identified no significant difference regarding cell proliferation between the analyzed groups

Influência da idade, do sexo e da hora do dia no desempenho em teste de labirinto

The increase of elderly population in the world and in Brazil has indicated the necessity of health systems capable to evaluate, to diagnose and to intervene in the conditions of health and disease of that segment. During that stage of human development, physical and cognitive changes happen and they are capable to influence the functional acting. It s important to distinguish the limit between the normal and the pathological. Besides the common changes during the aging, biological rhithmicity changes happen, as alterations in the cycle vigil-sleep that can influence in certain tasks performance. This study aimed to verify the influence of the age, of the sex and of the hour in a maze test performance. Eighty individuals were evaluated, 40 youths (20 men and 20 women) and 40 senior (20 men and 20 women). They were separated in 2 different groups that were tested at 9:00 o clock and at 15:00 o clock. Initially they were submitted to health evaluation, cognitive evaluation and of sleep quality and chronotype. They were instructed to accomplish the maze test whose time of execution was timed and registered. Significant differences were observed according to age for the masculine group between elderly in the morning and in the afternoon and in the feminine group between youth and elderly in the test accomplished in the morning and in the afternoon. Significant differences were not observed according to sex and hour of the day and also between attempts. In compare between the 30th and the31st, accomplished in a 15minutes of interval, significant difference was observed just for the elderly group in the morning and in the afternoon. We observed significant correlations in the maze test performance with the cronotype, with the age, with the education and with the cognitive acting. The maze test was capable to detect differences between age in the acting profile and in the evaluation of the information maintenance after 15 minutes, however it was not possible to verify difference between sex and hour of the day. Finally the correlations of the maze test with another varied may indicate your importance as coadjutant instrument in those functions evaluation

As relações de gênero no trabalho: uma análise da inserção das mulheres e homens na rede de fast food

The purpose of this study was investigate the sexual division of the work in a chain of fast food, in Natal, RN. These aspects were analyzed with the ways of organization of the work, being made a case study. The main objective of this survey was to analyze the influence of gender relations in the insertion of men and women in the job market and to analyze the question of feminine submission in the professional world. These questions were analyzed considering the current period of the worldwide capitalism, from the characteristics of productive process and the growth of the service sectors. The research was made with a group of workers on the production sectors; attendance, management and human resources at restfood store, where six clerks were interviewed. Through our research, it is possible to perceive the permanence of the sexual division at the job in the interior of the productive processes at Restfood, that puts the woman in a subordinate position in relation to the man. This result can be confirmed if we considerate that the women, on this chain of food, occupy in first place the function of waitress and on this, trere s no functional progression, while her workmates (the men) for occupying other functions can progress inside the company. It was also evidenced that in a context of globalization of the capital, deregulation and disrespect of labor laws, the capital acts without any respect to workers. That was what we observed at the interviewer speech; the scarcity of the conditions of work and the constant disrespect of the labor laws. This way, we could evidence that the scarcity of work conditions hit men and women, but it has a crueler face with the women, and this one reproduces itself, day by day in the process of social reproduction, through family life, insertion in the world of the work, information and received social education. So, the capital explores all of them, but the gender relations create to the capital, the possibility of a different degree of exploration, becoming this way, the women main victims herself

Caracterização epidemiológica e demográfica de homens com câncer de próstata

O estudo pretende identificar características demográficas e epidemiológicas em homens com câncer de próstata, atendidos no Hospital das Clínicas da Faculdade de Medicina de Botucatu/UNESP, entre 01/01/2000 e 31/01/2003. Foram colhidos dados em 78 de 94 prontuários, observando-se escolaridade, uso de tabaco, estado civil, idade, diagnóstico e sintomatologia. Utilizou-se metodologia quantitativa associada à estatística descritiva. Foram encontrados 50% com 1º grau incompleto, 27,39% não tabagistas, 87% casados, 43% entre 64 e 73 anos. Observou-se que 27,58% foram diagnosticados em 2000, sendo 63,20% aposentados e 20,70% com sintoma de jato urinário fraco. Apenas 20% tinham realizado exames preventivos e, desses, 77,90% possuíam 1º grau incompleto. O estudo foi feito nesse hospital por ser considerado de referência terciária da Direção Regional de Saúde de Botucatu -DIR XI¹. da amostra, 80% procuraram o serviço apresentando sintomas, o que leva a crer que ainda haja falta de orientação da população quanto ao câncer de próstata, principalmente quanto à incidência e prevalência relacionadas à idade, como fator de risco. O estudo evidencia subsídios para um melhor direcionamento da assistência a esses pacientes, permitindo um diagnóstico precoce e conseqüente possibilidade de cura, além da melhora na qualidade de vida.

Valores normativos e aptidão funcional em homens de 60 a 69 anos de idade

O objetivo deste estudo foi desenvolver valores normativos para a aptidão funcional e o índice de aptidão funcional geral (IAFG) para homens de 60 a 69 anos. Foram avaliados 112 idosos residentes em Florianópolis/SC ou Rio Claro/SP, por meio da bateria de testes da AAHPERD, que realizavam atividade física sistematizada, supervisionada e regularmente, há pelo menos 6 meses. A bateria é composta por cinco testes que avaliam a flexibilidade, coordenação, agilidade/equilíbrio dinâmico, força e capacidade aeróbia. Para a análise dos dados e construção dos valores normativos das aptidões funcionais e do IAFG, utilizou-se o cálculo de percentis. Foram utilizados como pontos de corte os percentis 20, 40, 60 e 80 para gerar as classificações: muito fraco, fraco, regular, bom e muito bom, respectivamente. O desenvolvimento de valores normativos pode servir como referência aos profissionais, para que possam melhor avaliar, orientar e prescrever atividade física para homens idosos.

Concepções de homens hospitalizados sobre a relação entre gênero e saúde

A saúde masculina é ainda pouco discutida. Estudos mostram que há um padrão social hegemônico sobre o masculino que influencia comportamentos preventivos de homens diante da saúde. Esta pesquisa, qualitativo-descritiva, investigou por meio da análise de conteúdo de entrevistas de dois homens hospitalizados, as suas concepções sobre gênero e saúde/adoecimento. Sob o ponto de vista masculino, homens e mulheres ficam doentes igualmente, embora as mulheres cuidem mais e preventivamente da sua saúde devido ao corpo reprodutivo. Os homens cuidam menos da saúde porque têm dificuldades em se afastar do trabalho, procuram por ajuda médica apenas diante de situações críticas que impõem limites na vida social e adoecem de modo mais severo. As concepções identificadas enfatizam a necessidade de elaboração de políticas públicas, que visem promover a saúde, específicas à população masculina.

Ativação muscular do quadril e do joelho em duas aterrissagens realizadas por atletas do sexo masculino

OBJETIVO: Comparar a atividade muscular antes e após o contato com o solo entre as aterrissagens unilateral (AU) e bilateral (AB) em atletas do sexo masculino. PARTICIPANTES: Quinze atletas masculinos de voleibol sem sinais e sintomas de lesões nas extremidades inferiores (13 ± 1 ano, 1,70 ± 0,12m, 60 ± 12kg). MENSURAÇÕES:Os participantes realizaram dois saltos verticais, aterrissando unilateralmente e bilateralmente. A atividade mioelétrica do reto femoral (RF), bíceps femoral (BF), adutores de quadril (AQ) e a relação BF/RF foram comparados entre as duas aterrissagens e entre as fases caracterizadas por 100ms antes (PRE) e 100ms após (POS) o contato com o solo. RESULTADOS: Em ambas as aterrissagens, a ativação do RF foi maior na fase POS em relação à PRE. Na comparação entre as aterrissagens dentro da mesma fase não encontramos diferenças estatísticas. Apesar de o BF não ter apresentado diferenças entre as fases PRE e POS em cada aterrissagem, sua ativação foi maior na AU. Os AQ apresentaram maior ativação na fase POS durante a AU, no entanto não houve diferenças quando comparadas as duas aterrissagens. A relação BF/RF apresentou valores maiores em ambas as aterrissagens na fase PRE. No entanto, não encontramos diferenças entre as aterrissagens. CONCLUSÃO: Os resultados sugerem que cada músculo apresenta um papel diferente durante a fase de aterrissagem em homens. Enquanto que o RF possui como principal função a frenagem da articulação do joelho e do movimento descendente, caracterizada pelo aumento da ativação na fase pós-contato, o BF parece atenuar a tensão articular do joelho em atividades de maior impacto, mantendo-se mais ativo durante todo o ciclo da AU. Já a maior ativação dos AQ após o contato com solo na AU evidencia a importância da região lombo-pélvica na estabilização pélvica em situações de grande instabilidade. Estudos futuros são necessários para determinar os efeitos da ativação muscular apresentada na imposição de cargas mecânicas potencialmente lesivas no joelho em atletas do sexo masculino.

Efeito de um novo produto fermentado de soja sobre os lípides séricos de homens adultos normocolesterolêmicos

This study was undertaken to verify the effect of a daily intake of a new fermented soy milk produced with Enterococcus faecium and Lactobacillus jugurti on the serum lipid levels in normocholesterolemic middle-aged men. The study was randomized, double-blind and placebo-controlled and was performed for a period of 6 weeks. Forty-four normocholesterolemic healthy, male volunteers, aged 40-55 years old were randomly separated in two groups: The F-group received 200 ml of the fermented product daily and the P-group received 200 ml of placebo (chemically fermented). The blood samples were drawn initially and after 3 and 6 weeks and serum values for total cholesterol, HDL-cholesterol and triglyceride were determined. The LDL-cholesterol value was estimated. No significant changes in the fermented group (F) were observed for total cholesterol, LDL-cholesterol or triglyceride levels, while the HDL-cholesterol level was significantly higher (p≤ 0,05) after 6 weeks. The total cholesterol and LDL-cholesterol levels were significantly higer (p≤ 0,05) in the placebo group (P), but no changes were found for the HDL-cholestrol and triglyceride levels during the experimental period. In conclusion, the intake of 200 ml/day of the fermented soy milk, produced with E.faecium and L. jugurti, for 6 weeks, did not affect the serum total cholesterol and LDL-cholesterol, and led an increase of 10% in the HDL-cholesterol level.

Análise comparativa de métodos de avaliação da composição corporal em homens sadios e em pacientes com doença pulmonar obstrutiva crônica: antropometria, impedância bioelétrica e absortiometria de raios-X de dupla energia

The aim of this study was to examine the agreement between the results of body fat (BF and BF%), fat-free mass (FFM) and FFM index (FFMI= FFM/height2) as estimated by skinfold anthropometry (ANT), bioelectrical impedance (BIA) and dual-energy X-ray absorptiometry (DXA) in two groups of men (> or = 50 y), one comprising healthy individuals (n=23) and the other, patients with chronic obstructive pulmonary disease (COPD) (n=24). Comparisons between body composition techniques were done by repeated measures ANOVA; the Bland & Altman procedure was used to analyse agreement. RESULTS AND CONCLUSIONS: 1) comparison between healthy and COPD groups showed significant differences between all studied variables; 2) in the healthy group, values for BF, BF%, FFM and FFMI were not significantly different when BIA or ANT was compared to DXA; however, in COPD, values for BF and BF% were significantly higher and for FFM and FFMI significantly lower when BIA was compared to DXA; in contrast, no differences were shown between values for these variables when ANT was compared with DXA; 3) Bland & Altman test, in both groups, showed no agreement between BIA and DXA and between ANT and DXA; it was also shown that body fat was overestimated and fat free mass underestimated by BIA in relation to DXA.

Razão de prevalências: Alcoolismo nas diferentes regiões geográficas do Brasil segundo o sexo

The present study applies a method of prevalence analysis to data obtained in two nationwide household surveys on alcohol use during life and dependence, for each of the sexes. The ratios of prevalences (R), for the lifetime alcohol use and dependence rates, between the two genders in the various Brazilian macro-regions, were calculated together with their respective 95% confidence intervals. It was found that lifetime use, both in 2001 and in 2005, was significantly greater in Brazilian males in all geographical regions. In 2001, the population of the North (male and female) had a higher rate of alcohol consumption than that in the Brazilian population as a whole and that in the Southeast. Dependence on the consumption of alcoholic drinks in 2001 and in 2005 was greater in the male sex, but similar among the various regions studied. It can be concluded that this method of analyzing the data on alcoholism could be of great use in assessing its magnitude and importance in terms of public health.
