Effect of beer consumption on plasma magnesium: randomized comparison with mineral water.

Moderate consumption of ethanol lowers mortality from coronary artery disease, and one of the possible mechanisms is an antiarrhythmic action. We therefore investigated the effect of a small daily dose of beer on plasma electrolytes. 52 men who seldom drank alcohol, clinically stable more than one year after coronary bypass surgery, were randomized to drink either 330 mL beer (containing about 20 g ethanol) or mineral water with similar potassium, magnesium, calcium and sodium content daily for 30 days. Plasma electrolytes and liver function indices, and also heart rate, blood pressure and weight, were measured before and after the trial period. The only significant before-and-after difference was in the group consuming beer, whose plasma magnesium rose from 0.89 (SD 0.01) to 0.98 (SD 0.02) mmol/L (P < 0.0025). This level of beer consumption did no obvious harm to liver function and its possibly beneficial effect on plasma magnesium deserves further investigation.

Long-term antianginal and antiischemic effects of mibefradil, the novel T-type calcium channel blocker: a multicenter, double-blind, placebo-controlled, randomized comparison with sustained-release diltiazem.

This study compared the efficacy, safety, and tolerability of mibefradil to sustained-release diltiazem in patients with chronic stable angina pectoris. At week 12, statistically equivalent mean increases in exercise tolerance test (ETT) duration of > 1 minute were observed in both groups. Similar improvements in time to onset of angina and time to persistent 1 mm ST-segment depression were also observed with both drugs. Large reductions in heart rate, blood pressure, and rate-pressure product were observed at each stage of the ETT among patients treated with mibefradil. Each drug was associated with at least a 70% reduction from baseline in anginal frequency and nitroglycerin consumption. Patients maintained on mibefradil during the withdrawal period had significant increases in all three ETT variables at week 16 compared with placebo. The effectiveness of mibefradil is comparable with sustained-release diltiazem in treating chronic stable angina pectoris, although mibefradil provides greater reductions in heart rate and cardiac workload.

Antecedents of adult interpersonal functioning: effects of individual differences in age 3 temperament.

We examined whether temperamental differences at age 3 are linked to interpersonal functioning in young adulthood. In a sample of over 900 children, we identified 5 distinct groups of children based on behavioral observations: Well-adjusted, undercontrolled, reserved, confident, and inhibited. At age 21, we assessed the children's interpersonal functioning in 4 social contexts: in the social network, at home, in romantic relationships, and at work. We found three patterns of relations: (a) Well-adjusted, reserved, and confident children defined a heterogeneous range of normative adult interpersonal behavior, (b) inhibited children had lower levels of social support but normative adjustment in romantic relationships and at work, and (c) undercontrolled children had lower levels of adjustment and greater interpersonal conflict across adult social contexts.

Gender differences in partner violence in a birth cohort of 21-year-olds: bridging the gap between clinical and epidemiological approaches.

This study describes partner violence in a representative sample of young adults. Physical violence perpetration was reported by 37.2% of women and 21.8% of men. Correlates of involvement in severe physical violence differed by gender. Severe physical violence was more strongly associated with unemployment, low educational attainment, few social support resources, polydrug use, antisocial personality disorder symptoms, depression symptoms, and violence toward strangers for men than for women. Women who were victims of severe physical violence were more likely than men who were victims to experience symptoms of anxiety. The findings converge with community studies showing that more women than men are physically violent toward a partner and with clinical studies highlighting violence perpetrated against women by men with deviant characteristics.

Personality differences predict health-risk behaviors in young adulthood: evidence from a longitudinal study.

In a longitudinal study of a birth cohort, the authors identified youth involved in each of 4 different health-risk behaviors at age 21: alcohol dependence, violent crime, unsafe sex, and dangerous driving habits. At age 18, the Multidimensional Personality Questionnaire (MPQ) was used to assess 10 distinct personality traits. At age 3, observational measures were used to classify children into distinct temperament groups. Results showed that a similar constellation of adolescent personality traits, with developmental origins in childhood, is linked to different health-risk behaviors at 21. Associations between the same personality traits and different health-risk behaviors were not an artifact of the same people engaging in different health-risk behaviors; rather, these associations implicated the same personality type in different but related behaviors. In planning campaigns, health professionals may need to design programs that appeal to the unique psychological makeup of persons most at risk for health-risk behaviors.

Moderate beer consumption and positive biochemical changes in patients with coronary atherosclerosis.

OBJECTIVES: The aim of this study was to evaluate the influence of moderate beer consumption on lipid metabolism and antioxidant activity in patients (pts) with coronary artery disease (CAD). SUBJECTS: Forty-eight male pts with CAD not alcohol beverages consumers were randomly divided into experimental (EG) and control (CG) groups, 24 pts each. SETTING: Rehovot University Hospital, Israel. INTERVENTION: Every patient of the EG during a period of 30 consecutive days consumed 330 ml of Maccabee beer (> 20 g of alcohol). The pts of the CG did not consume alcohol during the trial period. METHODS: A wide range of tests including total cholesterol, LDL-C, HDL-C, total tocopherol and alpha-tocopherol. RESULTS: Only in the pts of the EG were found a tendency to an increase of the level of HDL-C and a statistically significant rise in the level of total tocopherol (P < 0.025) and alpha-tocopherol (P < 0.025). CONCLUSIONS: Even a short period of moderate beer consumption leads to some favourable biochemical changes in blood of pts with CAD which are widely regarded as indicators of CAD prevention.

Moderate beer consumption and the blood coagulation in patients with coronary artery disease.

OBJECTIVES: To evaluate the influence of a short period of moderate beer consumption on the status of the thrombolitic activity in patients with coronary artery disease (CAD). SUBJECTS AND DESIGN: From 28 patients with two- or three-vessel CAD 22 were randomly assigned to an experimental group (EG) and six to control group (CG). Before and after completion of the study every one of the 28 patients was examined and a wide range of laboratory tests was performed. SETTING: A University Hospital in Israel. INTERVENTION: Of the EG, 22 patients consumed 330 mL of beer day-1 (20 g of alcohol) for the 30-day period in addition to the usual antiatherosclerotic diet. Patients of the CG did not consume alcohol beverages. MAIN OUTCOME MEASURES: Fibrinogen, prothrombin time (PT), coagulant activity of Factor VII (F VIIc) and Factor VII antigen (F VIIag), and plasminogen activator inhibitor (PAI) levels were studied. RESULTS: After the investigation a statistically significant decrease was found in F VIIc (P < 0.01) and F VIIag (P < 0.001) and to a lesser extent a decrease in the value of PAI. Fibrinogen and PT remained unchanged in the EG also. CONCLUSIONS: Even a short period of moderate beer consumption results in a decrease in thrombogenic activity. The only sensitive tests were F VIIc and F VIIag. The decrease in thrombogenic activity may be the main cause of decreased mortality in patients with CAD who consume moderate quantities of alcoholic beverages.

Daylength during pregnancy and shyness in children: results from northern and southern hemispheres.

An extreme degree of shyness in young children is a temperamental trait under modest genetic influence and characterized by distinct physiological profiles. Data from both the United States and New Zealand indicate that maternal exposure to short daylength during pregnancy, especially the midpoint of gestation, predicts an increased risk of subsequent shy behavior in children. Estimates of attributable risk indicate that approximately one-quarter of shyness prevalence can be linked to pregnancy during times of reduced daylength. This phenomenon might be mediated by changing concentrations of melatonin, serotonin, or other neurotransmitters or corticoids that are known to covary with seasonal variations in daylength.

Behavioral observations at age 3 years predict adult psychiatric disorders. Longitudinal evidence from a birth cohort.

BACKGROUND: This study provides, to our knowledge, the first empirical test of whether behavioral differences among children in the first 3 years of life are linked to specific adult psychiatric disorders: anxiety and mood disorders, antisocial personality disorder, recidivistic and violent crime, alcoholism, and suicidal behavior. METHODS: In a longitudinal-epidemiological study, 3-year-old children were classified into groups based on examiner observations of their behavior. At age 21 years, they were reassessed for psychopathologic functioning using standardized interviews based on DSM-III-R criteria. RESULTS: Although effect sizes were small, undercontrolled (includes children who are impulsive, restless and distractible) and inhibited (includes children who are shy, fearful, and easily upset) children differed significantly from comparison children in young adulthood. Under-controlled 3-year-olds were more likely at 21 years to meet diagnostic criteria for antisocial personality disorder and to be involved in crime. Inhibited 3-year-olds were more likely at 21 years to meet diagnostic criteria for depression. Both groups were more likely to attempt suicide, and boys in both groups had alcohol-related problems. Controls for family social class did not change the findings. CONCLUSION: Some forms of adult psychopathologic abnormality are meaningfully linked, albeit weakly, to behavioral differences observed among children in the third year of life.

Personality traits are differentially linked to mental disorders: a multitrait-multidiagnosis study of an adolescent birth cohort.

The authors assessed the relation between personality and mental disorder in a representative birth cohort of 897 men and women. Personality was assessed at age 18 with the Multidimensional Personality Questionnaire (MPQ; A. Tellegen, 1982), and 4 types of mental disorder (affective, anxiety, substance dependence, and conduct disorder) were assessed at ages 15, 18 and 21, using age-appropriate standardized diagnostic interviews. All disorder groups had MPQ profiles that were very different from those of controls. When comorbid cases were excluded, fewer significant differences between diagnosed cases and controls remained. Relations between personality and mental disorder were not affected by the measurement of disorder as continuous versus discrete, gender, or the age at which disorder was diagnosed. Relations between personality and mental disorders appear to be robust, and individual personality differences may be particularly relevant to understanding the most severe (comorbid) expressions of psychopathology.

Resilient, overcontrolled, and undercontrolled boys: three replicable personality types.

Three replicable personality types were identified in a sample of 300 adolescent boys and shown to generalize across African Americans and Caucasians. The types had conceptually coherent relations with the Big Five dimensions, ego resiliency, and ego control, and converged with three of the types identified by J. Block (1971). The behavioral implications of the types were explored using several independent data sources. Resilients were intelligent, successful in school, unlikely to be delinquents, and relatively free of psychopathology; Overcontrollers shared some of these characteristics but were also prone to internalizing problems; and Undercontrollers showed a general pattern of academic, behavioral, and emotional problems. This research demonstrates that replicable and generalizable personality types can be identified empirically, and that the unique constellation of traits defining an individual has important consequences for a wide range of outcomes.

Delay of gratification, psychopathology, and personality: is low self-control specific to externalizing problems?

We assessed the delay of gratification behavior of 428 twelve- and thirteen-year-old boys, half of whom were known to manifest symptoms of behavioral disturbance. Consistent with the hypothesis that low self-control is a risk factor specific to externalizing (aggressive and delinquent) disorders, boys who showed signs of externalizing disorders tended to seek immediate gratification in a laboratory task more often than both nondisordered boys and boys who showed signs of internalizing (anxious and depressed) disorders. In addition, children who were able to delay immediate gratification were described by their mothers as ego controlled, ego resilient, conscientious, open to experience, and agreeable. These results suggest that poor delay of gratification may be one of a select number of specific risk factors for externalizing disorder, and that good delay of gratification is linked to multiple adaptive tendencies in early adolescence.

Chronic aortic dissection presenting as a prolonged febrile disease and arterial embolization.

Aortic dissection most often is an acute event dominated by excruciating pain and other symptoms which suggest the diagnosis. Our report and a review of the medical literature demonstrate that chronic aortic dissection may, rarely, present as a prolonged febrile illness, with night sweats, weight loss, pleural effusion, and little or no pain. These symptoms may be associated with a markedly elevated erythrocyte sedimentation rate (ESR), anemia of chronic disease, and hyperglobulinemia. Awareness of this unusual presentation, a high index of suspicion, and confirmation by an appropriate imagine technique (CT or MRI of the chest or transesophageal echocardiography have a very high sensitivity) will result in earlier diagnosis and better patient outcome.

Psychiatric disorder in a birth cohort of young adults: prevalence, comorbidity, clinical significance, and new case incidence from ages 11 to 21.

Mental health data were gathered at ages 11, 13, 15, 18, and 21 in an epidemiological sample using standardized diagnostic assessments. Prevalence of Diagnostic and Statistical Manual of Mental Disorders (3rd ed. revised; American Psychiatric Association, 1987) mental disorders increased longitudinally from late childhood (18%) through mid-(22%) to late-adolescence (41%) and young adulthood (40%). Nearly half of age-21 cases had comorbid diagnoses; and comorbidity was associated with severity of impairment. The incidence of cases with adult onset was only 10.6%: 73.8% of adults diagnosed at age 21 had a developmental history of mental disorder. Relative to new cases, those with developmental histories were more severely impaired and more likely to have comorbid diagnoses. The high prevalence rate and significant impairment associated with a diagnosis of mental disorder suggests that treatment resources need to target the young adult sector of the population. The low new-case incidence in young adulthood, however, suggests that primary prevention and etiological research efforts need to target children and adolescents.

Does the electrocardiographic pattern of "anteroseptal" myocardial infarction correlate with the anatomic location of myocardial injury?

The current electrocardiographic (ECG) definition of anteroseptal acute myocardial infarction (AMI) is a Q wave or QS wave > 0.03 second in leads V1 to V3, with or without involvement of lead V4. To verify whether there is a correlation between the ECG pattern of anteroseptal AMI and the location of an AMI, we compared ECG, echocardiographic, and cardiac catheterization findings of 80 patients who fit the traditional definition of anteroseptal AMI. We found that 48 of 52 patients (92%) who presented with ST elevation in leads V1 to V3 had an anteroapical infarct and a normal septum. The culprit narrowing was more frequently found (in 85% of patients) in the mid to distal left anterior descending artery. We conclude that there is no correlation and that the ECG pattern traditionally termed anteroseptal AMI should be called an anteroapical AMI; the term anteroseptal AMI should be defined as extensive anterior wall AMI associated with diffuse ST changes involving the anterior, lateral, and occasionally, inferior leads.

Non-visualized left anterior descending artery revealed on selective conus artery catheterization.

Cardiac catheterization of a man with severe angina and anterior ischemia on exercise testing with perfusion imaging demonstrated normal anterior wall motion resting left ventriculography, but failed to visualize the left anterior descending (LAD) or conus artery on left and right coronary angiography. Selective contrast injection of a large conus artery originating from a separate ostium in the right aortic sinus demonstrated extensive collateral circulation to an LAD occluded at its origin from the left main coronary artery, thus providing essential information for subsequent patient management.
