Avaliação da atenção concentrada e memória em tabagistas com baixa carga tabágica

Introduction: Smoking is considered by World Health Organisation (WHO) a disease, since nicotine is addictive and cause physical, emotional and behavioral disorders in people who smoke. The objective of this study was to evaluate the concentrated attention and memory in smokers and nonsmokers, and the influence of one cigarette in this variables. Material and Methods: We selected two groups of subjects between 18 and 25 years, with no history of acute or chronic respiratory disease. Group 1 (G1) consist of 40 nonsmoking individuals and group 2 (G2) 40 smokers (who smoked less than 20 cigarettes per day, for up to 10 years). The subjects were tested for concentrated attention and memory test (AC Test), nonsmokers performed the test once, smokers performed the test twice, before smoking and after five minutes after smoking one cigarette. Smokers stayed without cigarret for one our before the first test. Results: Comparing the tests nonsmokers versus smokers first test, there was no significant difference (p> 0.05), however, the analysis of the two trials of smokers, showed improvement in concentrated attention and memory after smoke (p <0.0001). Conclusions: There was no difference in Concentrated Attention and Memory among nonsmokers and smokers in abstinence, however smokers showed significant improvement in AC Test after smoking.

Efeitos da terapia manual de Maitland em pacientes com lombalgia crônica

Introduction: The low back pain are a problema of health. Objective: to evaluate the effects of the Maitland´s manipulation in pain, fl exibility, functional capacity and quality of life of the patients with chronic low back pain. Method: Sxteen subjects, of both genders, with the age from 23-68 years old (48.69,± 11.61 years old) were evaluated by test sit and reach (TSA), Visual Analogue Scale (VAS) and answered the questionnaires of the quality of life Medical Outcomes Study 36- Item Short-Form Health Survey (SF-36) and the Roland-Morris Disability functional incapacity (RMDQ). The treatment was carried out twice a week, totaling 10 sessions. Each session lasted 30 minutes and consisted by Maitland´s techniques, applied as the symptoms evaluated at the beginning of each session. After 10 session, the subjects were re-evaluated. The data obtained in the assessments concerning the TSA and VAS were analyzed by Student t test, the data relating to the questionnaire were analyzed using the Wilcoxon non-parametric statistics test. For the interpretation was used signifi cance level of 5% (p≤0,05). Results: A signifi cant improvement was in the intensity of pain, disability, fl exibility and quality of life. Conclusion: The Maitland´s therapy showed effective, which suggests be an appropriate strategy for intervention for patients with chronic low back pain.

Qualidade de vida em mulheres com ausência ou presença de terapia de reposição hormonal

The objective of this study was to evaluate the quality of life (QL) of a group of menopausal women in the presence or absence of hormone replacement therapy (HRT). It consists of a cross-sectional analytical study involving women from the School Health Center - Unity Village Farmers' and Town Railway on the city of Botucatu. Participants were divided into two related groups of studies: run HRT and do not realize. We used the SF 36 and QRS, and a questionnaire to characterize the study population. No differences were seen when comparing the groups with regard to age, age at menarche and menopause. It was observed that 92% were white women and who have studied up to primary education (p = 0.0209), and those who had a partner (p = 0.0055), were the most reported changes in QL. The most frequent comorbidities were hypertension and diabetes, which is significantly more important in women without HRT. The account of the lower of QL was expressed by 28% of the sample, and the population obtained in MRS score more negative (p, 0.05). The correlation of the eight components of the SF36 and the MRS, with the presence or absence of TRH showed no significant differences. The concept of quality of life and evaluation of it is subjective and individual. However they can notice changes in QL, evidenced by instruments. One can see that menopause is not necessarily accompanied by changes in QL, however, when expressed, tend to be perceived more negatively. Despite the lower level of social and low education and women interviewed have QL as good. There is a need for studies to improve a more real relationship between HRT and QL

Terapia fotodinâmica e luz branca: aspectos analíticos e perspectivas da viabilidade do tratamento

Photodynamic Therapy (PDT) is a technique used to treat several types of lesions, such as cancer, microbial control, and esthetic dentistry cases. The performance of PDT involves the use of a photosensitizer (PS), which mainly will be located in cancer cells and is irradiated with visible light. This process, when it occurs in the presence of oxygen triggers the formation of reactive oxygen species that are cytotoxic to cells. These species cause cell death and subsequent tumor necrosis. The use of white light as a light source for multispectral Photodynamic Therapy and its consequences to the photodynamic effect is not yet completely established, and therefore there is interest in studying the parameters involved for analyzing the best conditions for applying treatment. The wavelength is crucial to improve the therapeutic effect, since both the optical properties of the biological tissue as the PS depend on these parameters. For FS studied in this work (Photogem®) are most often used wavelengths in the red region, due to their larger penetration depth in biological tissue. Thus, the light source becomes a fundamental aspect, their choice depends on the specific application and is based on the tumor location, light dose to be delivered and FS chosen. Despite all the advantages presented by lasers, the fact of having an emission spectrum essentially monochrome makes only one possible transition possible for the absorption of FS is used. Therefore, more extensive light sources such as light emitting diodes (LED), could be better used in some cases the laser, with the additional advantage of a reduced cost. Therefore, the choice of the white LED comes from an emission spectrum that still wider LED colors defined by allowing greater use of the several absorption bands and with varying depths of operation, according to the wavelength...

Caracterização do fator de intensidade de tensão em corpos trincados através do método dos elementos finitos

The industry generally has sought materials with high mechanical resistance, low density, thermal stability and corrosion resistance. In the aerospace industry, for example, the use of aluminum alloys, such as Al 2024-T351 and Al 7075-T7351, have become essential. However, the use of these materials often do not resulted in a satisfactory performance of the component, since the presence of cracks can cause total rupture of the component, even with a tension below the yield stress of the material, unexpectedly. In this work, these aluminum alloys were analyzed and samples were modeled by the finite element method. Moreover, in the models were applied two different types of cracks, central and edge crack, a vertical force was applied to result in a tension 70% of the yield stress of the material analyzed. Through stress asymptotic distribution in the region near the crack tip were calculated the values of the stress intensity factors for each crack length, after the stress intensity factors characterized were compared graphically with the values of fracture toughness found in the available literature

Terapia fotodinâmica na Endodontia: emprego de uma estratégia coadjuvante frente à infecção endodôntica

O tratamento endodôntico é de fundamental importância para abolir a infecção nos dentes com necrose pulpar. O sucesso desse tratamento depende: da eliminação eficiente da infecção no sistema de canais radiculares (SCR) e do correto selamento pela obturação dos canais radiculares. Devido à complexidade anatômica do SCR, certas áreas podem ser inacessíveis ao preparo biomecânico (PBM), portanto, o emprego de uma medicação intracanal potencializa a redução dos microrganismos (MO) e seus produtos tóxicos no SCR. Mesmo com o avanço técnico e científico da Endodontia, há MO que ainda sobrevivem ao PBM, sendo os principais responsáveis pela manutenção infecção endodôntica. Assim, novos tratamentos devem ser pesquisados. Com o advento dos aparelhos de laser e LED, surgiram alternativas de tratamentos na área da saúde, como a terapia fotodinâmica (TFD), que é um conjunto de procedimentos físicos, químicos e biológicos, que ocorrem após a administração de um agente fotossensibilizador (FS) ativado por meio de uma luz visível de comprimento de onda específico (laser ou LED) para destruir a célula-alvo, ou auxiliar no combate das infecções. Na Endodontia, foram demonstrados em estudos in vitro e in vivo que o emprego da TFD atua como um coadjuvante e potencializa a desinfecção do SCR, além de ser de fácil aplicação e não promover resistência microbiana. O objetivo da presente revisão é apresentar o estado atual da terapia fotodinâmica em Endodontia.

Influência da música preferida no desempenho e estados afetivos de idosos durante exercício de intensidade auto-selecionada

Low adherence to physical exercise programs is a factor that contributes to the high rates of physical inactivity worldwide. In this sense, strategies to improve the affective responses during exercise are used to impact adherence, as the use of music and self-selected exercise intensity. Despite the benefits of these strategies, there are few studies involving the combination of both (self-selected intensity and music), especially in the elderly population. Thus, the aim of this study was to investigate the influence of music on performance, ratings of perceived exertion (RPE) and on affective and motivational responses of elderly during walking exercise with self-selected intensity. Eleven elderly performed walking sessions on an athletic track in three conditions: without music, with motivational music and with oudeterous music. RPE, mood states, motivation, affective responses, session RPE and attitudes related to the experience of exercise were evaluated. Results demonstrated that both motivational and oudeterous music improved affective responses and decreased RPE. However, only the motivational music condition showed an effect on distance walked, the only presenting a consistent increase in distance. Therefore, it is concluded that the use of music, particularly motivational music, besides increasing the distance walked, reduces RPE and increase pleasure of the elderly during the exercise. Such strategy, in addition to potentially impact adherence positively, can lead to greater benefits and physical adaptations related to the training in the long term
