    Abstract:
    Recently, high-density lipoprotein particles (HDL-P) have been found to be more strongly inversely associated with coronary artery disease (CAD) risk than their counterpart, HDL cholesterol (HDL-C). Given that lifestyle is among the first targets in CAD prevention, we compared the associations of HDL-P and HDL-C with selected lifestyle factors. Methods and Results: We examined 789 Japanese participants of the INTERLIPID Study: men (n=386) and women (n=403) aged 40-59 years in 1996-1998. Participants treated for dyslipidemias were excluded. Lifestyle factors included alcohol intake, smoking amount, and body mass index (BMI). Multivariable linear regression was used for cross-sectional analyses of these factors with HDL-P, HDL-C, HDL-P size subclasses (small, medium and large) and mean HDL-P size. In men, higher alcohol intake was associated with higher HDL-P and higher HDL-C. The associations of alcohol, however, were strongest with HDL-P. A higher smoking amount tended to be associated with lower HDL-P and HDL-C. In contrast, BMI was not associated with HDL-P, but was strongly inversely associated with HDL-C. While alcohol intake favored larger mean HDL-P size, smoking and BMI favored a lipid profile with smaller HDL-P subclasses and overall smaller mean HDL-P size. Similar, but generally weaker results were observed in women.Although both HDL-P and HDL-C are parameters of HDL, they have different associations with alcohol, smoking and BMI.

    Background: Alcoholism is characterized by compulsive alcohol intake, but this critical feature of alcoholism is seldom captured in preclinical studies. Here, we evaluated whether alcohol‐preferring C57BL/6J mice develop compulsive alcohol drinking patterns, using adulteration of the alcohol solution with quinine, in a limited access choice paradigm. We assessed 2 independent aspects of compulsive drinking: (i) inflexible alcohol intake by testing whether mice would drink bitter alcohol solutions if this was their only source of alcohol and (ii) indifferent drinking by comparing intake of aversive and nonaversive alcohol solutions. Methods: Male C57BL/6J mice consumed alcohol for 2 or 8 consecutive weeks. The alcohol solution was then adulterated with graded quinine concentrations, and the effect on alcohol intake was determined. Results: C57BL/6J mice rapidly developed compulsive alcohol drinking patterns. Adulteration of the alcohol solution with an aversive quinine concentration failed to reduce intake, indicative of inflexible drinking behavior, after only 2 weeks of alcohol experience, although quinine adulteration did suppress the acquisition of alcohol drinking in naïve mice. After 8 weeks of alcohol consumption, the mice also became indifferent to quinine. They consumed an aversive, quinine‐containing alcohol solution, despite the simultaneous availability of an unadulterated alcohol solution. Prolonged alcohol ingestion did not alter the sensitivity to the bitter taste of quinine itself. Conclusion: These findings demonstrate the staged occurrence in mice of 2 distinct behavioral characteristics of alcoholism, i.e., inflexible and indifferent alcohol drinking.

    The effect of moderate amounts of alcohol on control of diabetes has been studied in twenty patients. No deterioration in control occurred after alcohol. Two subjects became severely hypoglycemic following alcohol. The implications of the use of alcohol by diabetic patients are discussed.

    Fifty-one healthy men aged 20–35 years kept daily drinking diaries for 4 weeks prior to a 90-mm drinking session of 1 ml of ethanol/kg body weight, taken as 4% alcohol by volume lager, at a constant rate, whilst fasting. This was followed by repeat breath-alcohol measurements for 90 min. Habitually light drinkers had significantly lower breath-alcohol levels than heavier drinkers up to 10 min post-drinking. Variation m bream-alcohol level was independent of habitual intake 15–90 min post-drinking. However, habitually light drinkers still had significantly lower blood-alcohol levels than heavy drinkers 30 min post-drinking. Group mean post-drinking breath-alcohol levels peaked at 20 min in light and moderate drinkers, at 10 min in heavy drinkers and at 5 min in very heavy drinkers. Wide individual variation in peak and rate of decline of breath-alcohol levels occurred independently of habitual intake and despite experimental control for factors influential on alcohol kinetics. Algorithms for alcohol intake and breath concentrations have limited application if drinking is prolonged. We suggest that pre-absorptive metabolism and/or delayed absorption of alcohol may contribute to lower breath-alcohol levels in habitually light drinkers for 10 min following alcohol intake under the conditions of this study.
