Prevalence of hypoalbuminemia in outpatients with HIV/AIDS.

Introduction: Hypoalbuminemia may predict progression of disease and mortality in patients with human immunodeficiency virus (HIV) infection/acquired immune deficiency syndrome (AIDS). This study was conducted to investigate the risk factors associated with hypoalbuminemia in outpatients with HIV/AIDS.

Methods: A cross-sectional study was performed in 196 outpatients with HIV/AIDS.

Loss to follow-up in a cohort of HIV-negative men who have sex with men: Project Horizonte.

Objective: The objective of this study is to estimate the attrition rates and evaluate factors associated with loss to follow-up between 1994 and 2011 in an open cohort of HIV-negative men who have sex with men.

Methods: The Project Horizonte is an open cohort study that aimed to assess the incidence of HIV infection, evaluate the impact of educational interventions, and identify potential volunteers for HIV vaccine trials. The rates of losses to follow-up were estimated for three periods (1994-1999, 2000-2005, and 2006-2011).

Determinants of Iron Deficiency Anemia in a Cohort of Children Aged 6-71 Months Living in the Northeast of Minas Gerais, Brazil.

Iron deficiency anemia is one of the most common nutritional disorders worldwide. The aim was to identify the prevalence and incidence of anemia in children and to identify predictors of this condition, including intestinal parasites, social, nutritional and environmental factors, and comorbidities. A population-based cohort study was conducted in a sample of 414 children aged 6-71 months living in Novo Cruzeiro in the Minas Gerais State.

Risk factors associated with HIV infection among male homosexuals and bisexuals followed in an open cohort study: Project Horizonte, Brazil (1994-2010).

Background: There has recently been an increase in HIV infection rates among men who have sex with men (MSM). This study aimed at investigating risk factors associated with incident HIV infection in a MSM cohort-Project Horizonte, Belo Horizonte, Minas Gerais, Brazil.

Methodology: This is a nested case-control study in an ongoing open cohort of homosexual and bisexual men, carried out in 1994-2010, during which 1,085 volunteers were enrolled.

Risk factors for seroconversion by Leishmania infantum in a cohort of dogs from an endemic area of Brazil.

Visceral leishmaniasis (VL) has recently emerged in various urban and peri-urban areas of Brazil and other countries. Understanding the urbanization of VL requires identification of risk factors associated with human and canine infection. To determine the predictors of risk for canine VL, a survey was conducted of 1,443 dogs, from which a cohort was selected (n = 455) and evaluated for approximately 26 months.

Dietary patterns in Brazilian patients with nonalcoholic fatty liver disease: a cross-sectional study.

Objective: Recent evidence suggests that non-alcoholic fatty liver disease is associated with diet. Our aim was to investigate the dietary patterns of a Brazilian population with this condition and compare them with the recommended diet.

Methods: A cross-sectional study was conducted on 96 non-alcoholic fatty liver disease patients before any dietetic counseling.

[Factors associated with changes in energy intake of women after treatment for breast cancer].

Purpose: To investigate changes in the dietary consumption as well as the influence of the general characteristics, of the sociodemographic, clinical and nutritional factors, and of the antineoplastic therapy on the changes in the energy intake of women from southern Brazil, before and after adjuvant therapy for breast cancer.

Methods: A non-randomized clinical study was conducted on 53 patients at a hospital of the public health network. Dietary information was collected with a food frequency questionnaire.

Longitudinal anthropometric assessment of infants born to HIV-1-infected mothers, Belo Horizonte, Southeastern Brazil.

Objective: To evaluate the growth parameters in infants who were born to HIV-1-infected mothers.

Methods: The study was a longitudinal evaluation of the z-scores for the weight-for-age (WAZ), weight-for-length (WLZ) and length-for-age (LAZ) data collected from a cohort. A total of 97 non-infected and 33 HIV-infected infants born to HIV-1-infected mothers in Belo Horizonte, Southeastern Brazil, between 1995 and 2003 was studied.

Longitudinal growth of infants born to HIV-1-infected mothers in Belo Horizonte, Brazil.

Objective: To prospectively evaluate growth parameters assessed by weight and length in infected and uninfected infants born to HIV-1-infected mothers and followed from birth to 18 months.

Methods: A cohort consisting of ninety-seven uninfected and forty-two infected infants born to HIV-infected mothers enrolled from 1995 to 2004, and admitted during their first 3 months of life at a referral Pediatric AIDS Clinic in Belo Horizonte, Brazil. Infants were followed until 18 months of age.

[Mixed linear regression model for longitudinal data: application to an unbalanced anthropometric data set].

A longitudinal data set is characterized by a time sequence of two or more observations from each individual. In cohort studies, these data are usually not balanced. A data set related to longitudinal height measurements in children of HIV-infected mothers was recorded at the university hospital of the Federal University in Minas Gerais, Brazil.
