To explore the relationship between serum DHEAS levels and blood pressure, obesity, smoking habits and drinking habits associated with onset of cardiovascular disease, we examined serum DHEAS levels in 90 males and 183 females, aged 35 to 62 years, who participated in a mass health examination conducted in a town of Aichi prefecture in 1992. The results were as follows. 1. Serum DHEAS levels were significantly higher in males than in females and decreased with age both sexes. 2. Age-adjusted serum DHEAS levels for both sexes decreased with blood pressure and BMI. 3. There were no apparent significance between age-adjusted serum DHEAS levels and smoking habits, whereas age-adjusted serum DHEAS levels were higher in groups of intake of ethanol volume 1-29 g/day than in the groups of intake of more than and less than ethanol volume 1-29 g/day. 4. Age-adjusted serum DHEAS levels were significantly decreased with the rise of sum of factors chosen as risk factor of cardiovascular disease disease in this study. It was suggested that serum DHEAS levels might be useful as an index of accumulation of risk factors of cardiovascular disease. Further studies should be performed to establish the possibilities as an index of genesis and prevention of cardiovascular disease.

Snoring and sleeping apnea are reportedly associated with morbidity. We used home monitoring (MESAM IV) to measure snoring and sleep apnea in 294 men aged 40 to 65 yr from the volunteer register of the Busselton (Australia) Health Survey. In this group, 81% snored for more than 10% of the night and 22% for more than half the night; 26% had a respiratory disturbance index (RDI) > or = 5, and 10% had an RDI > or = 10. There was a relatively low correlation between percentage of night spent snoring and RDI (rho = 0.47, p < 0.005). Subjective daytime sleepiness plus RDI > or = 5 occurred in a minimum of 3%. Obesity was related to snoring, RDI, and minimum SaO2 (all p < 0.0001). There was no relationship between age and either RDI or snoring, but increased age was related to minimum SaO2 < 85% (p < 0.05). Alcohol consumption was not related to sleep-disordered breathing. Smokers snored for a greater percentage of the night than nonsmokers (41 versus 31%, p = 0.01). We conclude that, in middle-aged men, both snoring and sleep apnea are extremely common, and in this age range both are associated with obesity but not with age. However, a high percentage of snoring is not essential for the occurrence of sleep apnea, nor does it necessarily indicate that apnea is present.

To determine the prevalence of coronary risk factors and coronary heart disease (CHD) in rural Rajasthan, 1150 randomly selected individuals in a cluster of villages in central Rajasthan have been studied. These included 805 men and 345 women. The prevalence of various coronary risk factors in the whole group were: Smoking 488 (42.4%); Diabetes (history): 5(0.4%); Alcohol intake: 146 (12.7%); Sedentary lifestyle: 797 (69.3%); Stressful life events: 48 (4.2%); Hypertension (BP > or = 140/90) 152 (13.2%); obesity (BMI > or = 27 Kg/M2): 194 (10.9%); and Truncal obesity (waist:hip > or = 0.93): 20.8%. The overall prevalence of CHD was 46.1/1000. Patients with CHD had a higher prevalence of male sex (67.9 vs 51.5%); educated persons (30.2 vs 28.8%); businessmen (13.2 vs 10.2%); smoking (47.2 vs 40.5%); sedentary lifestyle (75.5 vs 62.3%); stressful life events (7.5 vs 4.8%); and hypertension (26.4 vs 14.8%). On the other hand, persons without CHD had higher prevalence of alcohol intake (10.8 vs 7.5%); regular prayers (23.1 vs 22.6%); physically active lifestyle (37.7 vs 24.5%); obesity (13.6 vs 6.9%), and truncal obesity (21.0 vs 20.0%). The following risk factors emerged significant on statistical analysis (Odds ratio, 95% confidence intervals): male sex (1.99, 1.04 to 3.7); hypertension (2.04, 1.01 to 4.09); male smokers (1.80, 1.28 to 4.09); and sedentary lifestyle (1.86, 1.01 to 3.59). This study shows a low prevalence of CHD in rural population which is however more than previously reported studies from India.

The cytochrome P-450 (P-450) enzymes are collectively responsible for the bulk of oxidation of xenobiotic chemicals, including drugs, pesticides, and carcinogens. This biotransformation can result in either increased or decreased toxicity, depending on the situation. The regulation of individual P-450 enzymes is a complex subject, with examples of induction and direct inhibition and stimulation. Nutrients and food additives can modify P-450 activities and consequently influence toxicity. P-450s also influence the toxicity of potentially harmful materials found in foods, as well as some vitamins and natural products. Some of the foodstuffs and conditions that influence P-450 in experimental animals and in humans are protein, carbohydrate, lipid, obesity and fasting, water- and fat-soluble vitamins, minerals, sulfides, isothiocyanates, indoles, ellagic acid, capsaicin, terpenes, flavones, butylated hydroxytoluene and hydroxyanisole, charbroiled foods, ethanol, and (monosodium) glutamate and aspartate. Consideration is given, when possible, to differences in responses between animal models and humans.

To identify factors predicting aortic stiffness, we studied the modulus of elasticity of the thoracic aorta in relation to sex, obesity, blood pressure, physical activity, smoking, ethanol consumption, salt intake, and serum lipid and insulin levels in 55 healthy people born in 1954. A transverse cine magnetic resonance image of the thoracic aorta was made, and the modulus of elasticity was determined as brachial artery cuff pulse pressure/aortic strain, where strain was determined as the ratio of pulsatile aortic luminal area change to the diastolic luminal area. The average of measurements made in the ascending and descending aorta was used as the elastic modulus of the thoracic aorta. Habitual physical activity, smoking, and alcohol use were quantified by 2-month prospective daily recording and salt intake by 7-day food records. The aortic elastic modulus ranged from 100 to 2091 10(3) dyne/cm2 (median, 390 10(3) dyne/cm2). In multiple regression analyses, log10 aortic elastic modulus was related directly to mean blood pressure (standardized coefficient [beta] = .37, P = .002), serum high-density lipoprotein cholesterol (beta = .36, P = .012), square root of daily energy expenditure in physical activity (beta = .33, P = .005), and log10 serum insulin (beta = .27, P = .047) and inversely to serum low-density lipoprotein cholesterol (beta = -.26, P = .035). A relation to salt intake was also observed, but the regression slope was dependent on mean blood pressure (P = .005 for interaction). These data suggest that many modifiable constitutional and lifestyle characteristics may contribute to the stiffness of the thoracic aorta.

Adrenal arterial embolization with absolute ethanol was performed for the treatment of Cushing's syndrome. A 55-year-old woman was admitted to our hospital with complaints of obesity, hypertension, and back pain caused by left adrenal hyperplasia after surgical resection of the right adrenal gland. Therapeutic adrenal arterial embolization was performed by the coaxial technique using absolute ethanol (AE) as an embolic material. No severe complications were encountered during the procedure, and the patient was discharged without symptoms or abnormalities on laboratory tests.

Gout is a disease caused by deposits of sodium urate crystals in tissues. This disease, already known of Hippocrates, is now due to new causes, notably iatrogenic, and has new clinical forms. The typical initial attack usually occurs in men in their fifties and affects the big toe; in the absence of treatment it evolves towards chronic tophaceous gout. When gout occurs in subjects younger than 30 years, these must be investigated for enzyme deficit which is usually partial. The incidence of gout in women is ever increasing, being encouraged by treatments with diuretic drugs. Gout is often atypical, affecting predominantly the hands and with rapid development of tophus. In transplanted patients other drugs, such as cyclosporin, may induce an early, polyarticular and tophaceous gout. Alcohol is a facilitating factor of hyperuricaemia. Disturbances of metabolism, such as hyperlipidaemia, obesity or arterial hypertension, are often associated with hyperuricaemia. With an early and well-conducted treatment the passage to chronicity and the occurrence of complications can be avoided.

Regular alcohol consumption raises blood pressure and in drinking populations contributes significantly to the prevalence of hypertension. The effect of alcohol is additive to that of obesity. Reduction in alcohol intake leads to a lowering of blood pressure over 1-4 weeks. Acute alcohol ingestion in the evening may lower blood pressures overnight. Heavy weekend drinking may lead to a pressor effect for the succeeding 3 to 4 days. Certain personality types or heavy job strain increase susceptibility to pressor effects of alcohol. Alcohol consumption in the range of 1-3 standard drinks a day appears to have a protective effect against coronary disease and ischaemic stroke, which may be greater in those with a higher risk of vascular disease. At higher levels of consumption the risks of haemorrhagic stroke, cardiomyopathy and hypertension deaths predominate. Moderation of alcohol consumption to no more than two standard drinks a day can be an effective means of improving blood pressure control reducing drug requirements in treated hypertensives, and avoiding drugs in mild hypertensives. Moderating alcohol and reducing excess weight have additive effects in reducing overall cardiovascular risk.

The relationship between obesity, both general obesity (BMI) and central obesity (measured by the ratio of iliac and thigh circumferences), and a behavioural pattern, which includes alcohol consumption, smoking, stress and lack of sporting activity, was investigated in 467 middle-aged French working men. BMI and central obesity were closely correlated (r = 0.34). Alcohol consumption was positively associated with central obesity (P < 0.001) but it did not significantly influence BMI. BMI decreased with cigarette smoking (P < 0.001), but central obesity only increased significantly after adjustment for BMI (P < 0.05); thus for a given BMI, smoking was associated with a greater degree of central adiposity. Resting heart rate (considered as a measure of stress) was positively associated with both BMI and the iliac-thigh ratio (P < 0.01, P < 0.05), the latter association being due to general obesity. Sporting activity and BMI were only marginally associated (P < 0.07) but central obesity decreased with activity (P < 0.01). Jointly, alcohol consumption, cigarette smoking, the resting heart rate and sporting activity explained 8% of the variance in the iliac-thigh ratio; after adjustment for BMI these behavioural variables still explained 6% of the variance. Central adiposity, which has recently been described as a risk factor for coronary heart disease, non-insulin dependent diabetes and hypertension, was significantly associated with a potentially modifiable behavioural pattern.

In this study we examined the ability of intraperitoneal cholecystokinin COOH-terminal octapeptide (CCK-8; 0.2, 0.6, and 2.0 micrograms/kg) to suppress food intake in rats that had consumed a control diet, 6-8 g.kg-1.day-1 of ethanol (EtOH) in sucrose, or sucrose alone for 6 mo. Both the EtOH- and sucrose-fed rats developed significant dietary obesity. After 3 mo, the EtOH group was significantly more sensitive to CCK-8 than the sucrose and control groups, while the responses of the sucrose and control groups were comparable. In contrast, after 6 mo the EtOH and sucrose groups' response to CCK-8 was no longer significantly different. After 6 mo there were no significant differences in basal or postprandial plasma CCK-8 levels. The sucrose group had significantly higher basal insulin levels than the control and EtOH groups, and postprandial insulin levels, relative to basal, were significantly elevated in the EtOH group. Basal glucose levels did not differ among groups. Postprandial glucose levels (relative to baseline) were significantly lower in the EtOH group compared with the other groups and in fact never rose above baseline levels. These results are consistent with the hypothesis that EtOH, when taken on a chronic basis, increases the sensitivity to CCK-8.
