Heavy alcohol consumption is a risk factor for developing atrial fibrillation, but whether chronic alcohol use affects left atrial volume is unknown. We evaluated the association of self-reported alcohol consumption with 5-year change in left atrial volume among patients with coronary heart disease (CHD).

We studied 601 participants with stable CHD who underwent 2-dimensional echocardiography at baseline (2000-2002) and after 5 years of follow-up (2005-2007). Alcohol consumption was determined at baseline with the use of the Alcohol Use Disorders Identification Test consumption questions (AUDIT-C), with a standard cutoff point of ≥3 used to define at-risk drinking. We used logistic regression to evaluate the association of baseline alcohol use with 5-year increase in left atrial end-systolic volume index (defined as being in the highest tertile of percent change).

After adjustment for covariates, each standard deviation (2.4-point) increase in AUDIT-C score was associated with a 24% greater odds of experiencing a 5-year increase in left atrial volume index (adjusted odds ratio [OR] 1.24, 95% confidence interval [CI] 1.04-1.48; P = .02). Compared with the 369 participants who had AUDIT-C scores of <3, the 171 participants with scores of 3-5 had a 51% greater odds (OR 1.51, 95% CI, 1.11-2.25) and the 61 participants with scores of >5 a 98% greater odds (OR 1.98, 95% CI, 1.10-3.56) of experiencing a 5-year increase in left atrial volume index.

In patients with CHD, heavier alcohol consumption is associated with a 5-year increase in left atrial volume. Whether greater left atrial volume contributes to the increased risk of atrial fibrillation associated with alcohol use deserves further study.

    ABSTRACT: The aim of study was to test the usefulness of Moynihan questionnaire in the evaluation of knowledge on healthy diet of patients undergoing cardiology rehabilitation. We enrolled 51 patients (pts): 41 men and 10 women, mean age 67.97 +/-11.2 years. The case study included: 21 pts that underwent coronary bypass surgery, 16 pts replaced plastic tube, 14 pts had surgery for the other reasons. All pts underwent nutritional investigation by a dietitian. Anthropometric and biochemical parameters were detected and, by the end, the Moynihan questionnaire was administrated. Pts underwent nutritional coaching, and questionnaire and dietary assessment were rechecked after 3 months. At baseline, the mean Questionnaire score was 22.4 +/- 3.2 points, decreased to 20.6 +/-3.1 points after 3 months (p<0.05). A detailed analysis of the questions showed that the major informations gaps were related to consumption of fruits and vegetables, consumption of fat and salt. In addition pts have acquired more general knowledge about food composition. The Moynihan questionnaire is an useful instrument of evaluation of dietary knowledge even in selected patients population. In the present study involving patients after cardiac surgery the main difficulties were related to high age of pts, the low cultural level and, mainly, to the post-surgery stress. However, an increase of correct answers as well as an increased knowledge about food composition were detected after educational intervention performed by the dietitian.

    ABSTRACT: Melatonin (N-acetyl-5-methoxytryptamine) is a molecule implicated in multiple biological functions. Its level decreases with age, and the intake of foods rich in melatonin has been considered an exogenous source of this important agent. Orange is a natural source of melatonin. Melatonin synthesis occurs during alcoholic fermentation of grapes, malt and pomegranate. The amino acid tryptophan is the precursor of all 5-methoxytryptamines. Indeed, melatonin appears in a shorter time in wines when tryptophan is added before fermentation. The aim of the study was to measure melatonin content during alcoholic fermentation of orange juice and to evaluate the role of the precursor tryptophan. Identification and quantification of melatonin during the alcoholic fermentation of orange juice was carried out by UHPLC-QqQ-MS/MS. Melatonin significantly increased throughout fermentation from day 0 (3.15 ng/mL) until day 15 (21.80 ng/mL) reaching larger amounts with respect to other foods. Melatonin isomer was also analysed, but its content remained stable ranging from 11.59 to 14.18 ng/mL. The enhancement of melatonin occurred mainly in the soluble fraction. Tryptophan levels significantly dropped from 13.80 mg/L (day 0) up to 3.19 mg/L (day 15) during fermentation. Melatonin was inversely and significantly correlated with tryptophan (r = 0.907). Therefore, the enhancement in melatonin could be due to both the occurrence of tryptophan and the new synthesis by yeast. In summary, the enhancement of melatonin in novel fermented orange beverage would improve the health benefits of orange juice by increasing this bioactive compound.
