One-year longitudinal association between changes in dietary choline or betaine intake and cardiometabolic variables in the PREvención con DIeta MEDiterránea-Plus (PREDIMED-Plus) trial.

Background: Choline and betaine intakes have been related to cardiovascular health.

Objectives: We aimed to explore the relation between 1-y changes in dietary intake of choline or betaine and 1-y changes in cardiometabolic and renal function traits within the frame of the PREDIMED (PREvención con DIeta MEDiterránea)-Plus trial.

Methods: We used baseline and 1-y follow-up data from 5613 participants (48.

[A comparison between three questionnaires and laboratory tests for the detection of alcoholism in general practice].

By means of a case/control study, an attempt was made to identify the different questionnaires and biological tests which might be used in the General Practice consulting room for the detection of alcoholic patients. A comparison was made between the CABE, MALT, and Skinner questionnaires, and the MCV, AST, ALT, GGT triglyceride, cholesterol, uric acid, bilirubin and glycemia biological tests. Sensitivity, specificity, predictive value and diagnostic efficiency were studied in a group of 37 confirmed alcoholics and 25 controls making up a population with a high prevalence of alcoholism.
