OBJECTIVES We investigated potential microenvironmental risk factors for visceral leishmaniasis in urban and suburban areas, and developed risk scores to characterize the household and the neighborhood. These scores may be useful to identify microenvironments within cities that place residents at greater risk of visceral leishmaniasis. METHODS In this(More)
INTRODUCTION Despite improvement in clinical treatment for HIV-infected patients, the impact of antiretroviral therapy on the overall quality of life has become a major concern. OBJECTIVE To identify factors associated with increased levels of self-reported quality of life among HIV-infected patients after four months of antiretroviral therapy. METHODS(More)
OBJECTIVE To investigate the association between physical activity (eg, energy expenditure) and survival over 11 years of follow-up in a large representative community sample of older Brazilian adults with a low level of education. Furthermore, we assessed sex as a potential effect modifier of this association. MATERIALS AND METHODS A population-based(More)
OBJECTIVE This paper describes the development of the Protocol for Identification of Problems for Rehabilitation (PLPR), a tool to standardize collection of functional information based on the International Classification of Functioning, Disability and Health (ICF). DEVELOPMENT OF THE PROTOCOL The PLPR was developed for use during the initial contact with(More)
This article aims to evaluate the items used to measure functional capacity in the 2010 Health Survey in Greater Metropolitan Belo Horizonte, Minas Gerais State, Brazil, using Item Response Theory. We analyzed the scale's dimensionality, the items' position and discriminatory power, and the precision of the functional capacity estimate. The study was based(More)
BACKGROUND The measurement of CD4+ T-cell (CD4) counts is a strong predictor of progression to AIDS and a means of monitoring antiviral therapy (ART). The success or failure of controlling virus levels in untreated patients or those taking ART may be associated with treatment adherence, habits, correlated infections unrelated to HIV, cancer,(More)
The aim of this study was to assess the agreement of four renowned interaction lists on potentially severe warfarin drug interactions (DI) in outpatients at a university hospital in Brazil, specifically in subgroups of Trypanosoma cruzi-infected and non-infected patients and those with previous bleeding episodes. This was a cross-sectional study in which(More)
BACKGROUND Longitudinal studies often employ complex sample designs to optimize sample size, over-representing population groups of interest. The effect of sample design on parameter estimates is quite often ignored, particularly when fitting survival models. Another major problem in long-term cohort studies is the potential bias due to loss to follow-up.(More)
