Dynapenic abdominal obesity in hospitalized elderly patients with acute myocardial infarction.

Obesity and dynapenia are cardiovascular risk factors. When present together, it is called dynapenic abdominal obesity and can potentiate adverse outcomes. This study aims to estimate the prevalence of dynapenic abdominal obesity and its relationship with prognostic markers in patients with acute myocardial infarction (AMI).

Excess weight in adolescents and associated factors: data from the ERICA study.

Objective: To estimate the prevalence of excessive weight and to identify associations with socioeconomic, demographic, biological, and lifestyle factors in adolescents.

Methods: It is a cross-sectional school-based study, with a stratified and complex sample. The evaluated individuals were adolescents (2404), aged 12-17 years old, participating in the Study of Cardiovascular Risk Factors in Adolescents (ERICA).

OVERWEIGHT IN ADOLESCENTS: FOOD INSECURITY AND MULTIFACTORIALITY IN SEMIARID REGIONS OF PERNAMBUCO.

Objective: To investigate context of overweight adolescents from the semiarid and rural areas of Pernambuco, considering the multifactorial nature of the determinants of being overweight, and the food and nutritional insecurity conditions of the region.

Methods: A population based cross-sectional study was conducted from September to October 2015. The nutritional status of adolescents was assessed by body mass index (BMI) and classified by the BMI/Age indicator, according to sex.

Cachexia in hospitalized patients with heart failure.

Aims: to evaluate cachexia prevalence in hospitalized heart failure (HF) patients by comparing two methods for diagnosing cachexia and alterations in each component involved in its diagnosis.

Method: a cross-sectional study, involving patients diagnosed with HF and admitted between April and August 2015 to a public hospital in the Brazilian Northeast. Cardiac cachexia was defined using the Cachexia Consensus criteria (Washington, DC), which defines cachexia as ≥ 5% unintentional weight loss in the previous 12 months or a body mass index (BMI) ≤ 20.

Phase Angle as a Sarcopenia Marker in Hospitalized Elderly Patients.

Background: Phase angle (PhA) has been proposed as a parameter to predict clinical outcomes and mortality for various diseases. Several studies have considered it an important nutrition assessment tool. However, the usefulness of this parameter as a sarcopenia marker has not yet been evaluated.
