Alcoholic beverage consumption, changes in blood pressure, and incidence of hypertension in the Longitudinal Adult Health Study (ELSA-Brasil).

Objectives: Alcohol consumption is generally associated with increased risk of hypertension. We aimed to investigate, prospectively, the effect of alcoholic-beverage consumption on blood pressure (BP) and incidence of hypertension, after a 4-y follow-up, in participants of the Longitudinal Adult Health Study (ELSA-Brasil).

Methods: We analyzed information from 3,990 participants (ages 35-74 y), men and women, from educational and research institutions, at baseline (2008-2010) and follow-up (2012-2014).

[Sodium/potassium urinary ratio and consumption of processed condiments and ultraprocessed foods].

Introduction: one of the changes in diet is related to its content of sodium (Na) and potassium (K). Greater use of condiments and processed foods contributes to these changes and the Na/K ratio can be used as a marker of this consumption. Objective: to evaluate the association between Na/K ratio and consumption of industrialized condiments and ultra-processed foods.

A multianalyte Dot-ELISA for simultaneous detection of malaria, Chagas disease, and syphilis-specific IgG antibodies.

A multianalyte Dot-enzyme-linked immunosorbent assay (Dot-ELISA-Multi) with Trypanosoma cruzi epimastigote alkaline extract (EAE), trypomastigote excreted-secreted antigen (TESA), recombinant protein derived from 19-kDa C-terminal region of the Plasmodium vivax merozoite surface protein 1 (PvMSP1(19)), Plasmodium falciparum Zwittergent extract (Pf-Zw), and Treponema pallidum Zwittergent extract (Tp-Zw) was standardized and evaluated as a method for surveying IgG-specific antibodies in Chagas disease, malaria, and syphilis in a single test. The study was carried out on serum samples from 52 patients with chronic Chagas disease, 103 individuals with current (parasitemic) or past malaria (aparasitemic), 43 patients with syphilis, 21 individuals with heterologous antibodies, and 100 blood donors. Dot-ELISA-Multi yielded 99% specificity for Chagas disease and 100% for malaria and syphilis.
