Metabolic disorders and cardiovascular risk in people living with HIV/AIDS without the use of antiretroviral therapy.

Introduction: Metabolic disorders in people living with HIV/AIDS (PLH) have been described even before the introduction of antiretroviral (ARV) drugs in the treatment of HIV infection and are risk factors for cardiovascular diseases. Based on this, the purpose of this study was to assess metabolic disorders and cardiovascular risk in PLH before the initiation of antiretroviral treatment (ART).

Methods: This was a cross-sectional descriptive study of 87 PLH without the use of ART, which was carried out between January and September 2012 at a specialized infectious diseases center in Minas Gerais, Brazil.

Prognostic value of computed tomographic pulmonary angiography and the pulmonary embolism severity index in patients with acute pulmonary embolism.

Pulmonary embolism is a serious and potentially fatal disorder. Pulmonary embolism risk stratification may allow early hospital discharge and outpatient treatment for low-risk patients. Also, it may prevent death by early medical intervention in high-risk groups.

The long-term course of factor VIII inhibitors in patients with congenital haemophilia A without immune tolerance induction.

The development of alloantibodies that inhibit or neutralise the function of factor VIII is considered the most serious complication of the treatment of congenital haemophilia A. In order to describe their course without immune tolerance induction (ITI), we documented data on all performed inhibitor tests with dates as well as on clotting factor infusions of all consecutive patients who were treated in our centre between 1993 and 2006. Patients were tested every 7.

[Spatial-temporal distribution of potential blood donors at the Hemominas Foundation, Belo Horizonte, Minas Gerais State, Brazil, in 1994 and 2004].

The main goal of this study was to describe the spatial and temporal distribution of candidates for blood donation in Belo Horizonte, Minas Gerais State, Brazil, who appeared at the Hemominas Foundation in 1994 and 2004. The study also compared the candidates for age, gender, and clinical approval for blood donation in space and space-time. Data were obtained from a cross-sectional study for 1994 and were randomly selected from all donor candidates for 2004.

[Emerging and reemerging rickettsiosis in an endemic area of Minas Gerais State, Brazil].

Sera included 331 samples from schoolchildren from an endemic area and 142 samples from schoolchildren from a non-endemic area in the county.
