Brazil's staple food and incident diabetes.

Objective: The aim of this study was to investigate the association of Brazil's staple food, rice, beans and manioc, and the incidence of type 2 diabetes mellitus type 2 (T2DM) in adults assisted by a Brazilian Family Doctor Program (FDP).

Methods: The baseline information was collected on visits to 13 units of the FDP from July 2006 to December 2007 (CAMELIA Study). The units were revisited by trained researchers between July and December 2011, who reviewed medical records of all participants of the baseline.

Heart failure with preserved ejection fraction and systolic dysfunction in the community.

Background: In developed countries, heart failure with preserved ejection fraction (HFpEF) is more prevalent than heart failure with reduced ejection fraction (HFrEF) in the community. However, it has not been completely established if this fact is also observed within our community.

Objective: To determine the most prevalent form of heart failure (HFpEF or HFrEF) and whether the prevalence of HFpEF is higher in the community.
