Depression and adherence to antiretroviral treatment in HIV-positive men in São Paulo, the largest city in South America: Social and psychological implications

OBJECTIVES: The aim of the present study was to investigate the prevalence of depression and adherence to antiretroviral treatment in two groups of individuals: men who have sex with men (MSM) and men who have sex with women (MSW). METHODS: Two hundred and sixteen participants (MSM=116; MSW=100) who visited the Clinics Hospital of the School of the Medicine of the University of São Paulo completed two independent surveys (the BECK Depression Inventory and an adherence self-declared questionnaire) to evaluate their depression status and adherence to antiretroviral treatment, respectively. RESULTS: The study highlighted a positive relationship between depression and low adherence to Highly Active Antiretroviral Therapy in these patients regardless of age and sexual orientation. In addition, MSM subjects were two times more prone than MSW subjects to develop depression symptoms. White or mixed race men showed 7.6 times greater adherence to treatment than black men. The probability of complete adherence to treatment was 3.8 times higher in non-depressed subjects than in depressed subjects regardless of their ethnicity. The chance of developing depression was 4.17 times higher for an individual with non-adherent behavior than for an adherent individual. CONCLUSIONS: Individuals with low adherence rates have proportionally higher depression rates. Depressed men tend to show less adherence to treatment. Black but not mixed race or white men show less adherence to Highly Active Antiretroviral Therapy and have a greater chance of developing depression, which directly interferes with adherence. The chances of developing depression are four times greater for a patient with non-adherent behavior than for a patient with adherent behavior

Heráclito entre Hegel e Nietzsche

Nesse artigo pretendo confrontar o pensamento de Hegel e de Nietzsche à luz da chamada filosofia trágica. Trata-se especificamente de avaliar a proeminência de Hegel como filósofo trágico. Nesse sentido, visamos primeiramente caracterizar a filosofia trágica em sua relação com uma possível afirmação do devir, para finalmente apontar essa relação em Hegel e em Nietzsche. Nesse percurso, entretanto, tomaremos Heráclito como referência, tanto no discurso nietzschiano, quanto no hegeliano. Caso tenhamos sucesso, veremos que a filosofia de Hegel, apesar de conter uma valorização do tempo e da transitoriedade, acaba por determinar esse devir no âmbito da teleologia; distanciando-se assim da filosofia trágica proclamada por Nietzsche

The role of the focusing field profile on the stability of periodically focused particle beams

In this paper, the role of the focusing field profile on the stability of periodically focused particle beams is investigated, paying special attention to the transport within the new regions of stability found recently for vacuum-phase advances well above 90° [R. Pakter and F. B. Rizzato, Phys. Rev. Lett. 87, 044801 (2001)]. In particular, a solenoidal focusing field profile that goes from a smooth sinusoidal-like function to a sharp-edged step-funcion as a continuous parameter is varied is considered. It is shown that the new regions are always present, but may be very sensitive to changes in the focusing field profile. Specifically, as the focusing field becomes more localized, the new regions become narrower, occur at higher vacuum phase advances, and present a larger number of nonlinear resonances and chaos in the beam envelope phase space. Although in all the cases analyzed here it was found that there is a relatively thick layer of regular trajectories isolating the matched solution from the chaotic region, self-consistent simulations show that envelope phase-space chaos may affect beam dynamics, leading to some small emittance growth
