Cardiovascular disease is one of the major causes of death among native Americans. Ischemic heart disease has been relatively uncommon in the past, but this entity is rapidly becoming more frequent among Indians as a result of Western acculturation (Western high-fat diet, smoking, sedentary lifestyle). Hypertension remains a major problem in native American populations. Hypertension is often inadequately detected and treated in Indians. Rheumatic fever and rheumatic heart disease are moderately common and apparently in decline among native Americans. Finally, the fetal alcohol syndrome with its accompanying cardiac malformations is all too common among North American Indians. The amount of information available concerning cardiovascular disease in native Americans is rather small. Considerably more attention should be paid to this area in the future.

Several questions in the 1985 Health Promotion and Disease Prevention Questionnaire, which was part of the 1985 National Health Interview Survey, addressed respondents' consumption of alcohol. Sociodemographic characteristics, knowledge of health risks related to heavy drinking, health practices, and the prevalence of certain health conditions were examined in relation to drinking levels. Although cause-effect relationships should not be inferred from the associations, the findings suggest some provocative areas for prevention and research. Heavier drinkers were more commonly found among men than women. Level of drinking was associated positively with years of education and family income, but was inversely related to age. Compared with light drinkers, heavier drinkers were much more likely to drive after they had had too much to drink. While more than 90 percent of the population knew that heavier drinking increases the risk of 'liver cirrhosis, less than half knew about the increased risk of throat cancer and cancer of the mouth. Most respondents aged 18-44 years (80 percent or more) knew that heavy drinking increases the chance of adverse pregnancy outcomes, and more women than men (62 versus 49 percent) had heard of fetal alcohol syndrome (FAS). However, 70 percent or more of those who had heard of FAS described the syndrome as a newborn addicted to alcohol rather than a child born with certain birth defects. Heavier drinkers of both sexes were less likely than others to be nonsmokers, and moderate drinkers were more likely than others to exercise or play sports regularly. Moderate drinkers also tended to have lower lifetime prevalence rates than others for hypertension and heart trouble.

In a clinical and follow-up study of the progeny of alcoholic parents the author investigated embryopathic/dysontogenetic disorders ("oligosymptomatic" forms of alcoholic embryopathy, mental infantilism, hyperdynamic syndrome and the syndrome of cerebrospinal fluid hypertension) exerting a pathoplastic effect on the deviant behaviour of adolescents. The author has developed approaches toward a multiple modality therapy and rehabilitation of these patients in conditions of a special school for adolescents with deviant behaviour. A hypothesis is advanced as to the relationship between embryopathic/dysontogenetic disorders with embryofetotoxic effect of the mother's alcoholism on the fetus during pregnancy.

This paper reviews the potential health risks for persons who consume the newly available "non-alcoholic" or "de-alcoholized" beverages which may contain trace amounts of ethanol (less than 0.5% by volume). The discussion includes relative risk rates for chemical dependency, fetal alcohol syndrome, chemical and natural hypersensitivity, cancer, cardiomyopathy, hypertension and cirrhosis for those who drink standard alcoholic drinks and "non-alcoholic" drinks. It is concluded that non-alcoholic drinks pose little risk for developing alcohol related problems based on our current physiological and psychocultural knowledge.

Ethanol consumption and spontaneous (essential) hypertension are important fetal and maternal risk factors. Alone, they contribute to embryopathy (fetal alcohol syndrome) or maternal organ pathology and fetal loss in hypertensive pregnancies. Combined, the effects of ethanol consumption on the progress of a hypertensive pregnancy have not been adequately investigated. In the present study, groups of O-A strain genetic hypertensive (SHR: groups 1 and 2) and Wistar-Kyoto normotensive (WKY: groups 3 and 4) pregnant rats were given 20 ml/kg of distilled water by gavage to serve as controls [groups 1 (SHR) and 3 (WKY)] or 3.2 g/kg of ethanol [groups 2 (SHR) and 4 (WKY)] from days 6 to 15 of gestation. During acclimation, hypertension developed in SHR rats (WKY pressures were 105 to 114 mm Hg; SHR pressures were 137 to 148 mm Hg). From day 6 to 15 of gestation, ethanol-consuming rats (groups 2 and 4) had higher arterial pressures than controls (groups 1 and 3). Pregnant SHR rats given ethanol did not experience a prebirthing hypotension. On gestation day 20, most offspring (84%, group 2; 86%, group 4) of alcoholic dams were dead or malformed. Intrauterine growth retardation occurred in group 4. Hydrocephalus, microphthalmia, and mild hydronephrosis and hydroureter were common in live offspring of group 2 dams. Hydronephrosis and hydroureter were increased in group 4 pups. Variant cranial ossification was noted in group 2 and 4 pups. These preliminary data suggest an altered hypertensive response during pregnancy in alcohol-consuming rats and confirm the embryopathic effects of relatively high levels of ethanol consumed during the critical period of organogenesis in two additional strains of rats.

Pharmacologically relevant concentrations of ethanol (0.01-0.3 g/%) were perfused via the fetal circulation in isolated human placental lobules. This resulted in a dose-related rise in fetal arterial pressure, which at 0.3 g/% ethanol, was 10.1 +/- 1.1 mmHg above the pre-drug baseline. The pressor responses to ethanol were (i) rapid in onset, reaching a stable plateau within 5-10 min following administration, (ii) readily reversible by perfusion with drug-free media, (iii) non-tachyphylactic and (iv) largely inhibited by the cyclo-oxygenase inhibitor, inhibitor, indomethacin (5 microM). This pressor action of ethanol in the fetal circulation may contribute to the pathogenesis of the fetal alcohol syndrome as well as represent an underlying mechanism of ethanol-induced hypertension.

The illicit use of cocaine has increased dramatically over the last 10-12 years. There has been a corresponding increase in cocaine abuse among obstetric patients and in the number of "cocaine babies." According to some estimates, these children make up more than half of the drug-associated births. This problem is therefore a major public health concern. Consequently, our laboratory investigated the effects of prenatal cocaine exposure on hearing, vision, growth, and exploratory/stress behavior. This chapter summarizes the literature on animals and humans on these topics and presents new observations from our laboratory. In terms of maternal toxicity, prenatal cocaine exposure causes hypertension, placental abruption, spontaneous abortion, poor pregnancy weight gain, and undernutrition secondary to appetite suppression. Some offspring effects include in utero growth retardation, cephalic hemorrhage, fetal edema, altered body composition, congenital malformations, and even pre- and postnatal death. The offspring can also exhibit a variety of behavioral, visual, hearing, and language disorders. Differential effects of animal strain and late gestational cocaine exposure are discussed. Comparisons are made between prenatal cocaine, the fetal alcohol syndrome, and the effects of prenatal undernutrition. Recommendations for clinical assessment and intervention are made.

The number of pregnancies following liver transplantation is increasing due to better patient and graft survival and quality of life. Out of 156 women of a reproductive age, there were 19 pregnancies in 16 women, 12 on CsA and seven on tacrolimus, which occurred between 7/92 and 1/97. The median age of the women was 27.9 yr, median time after transplantation 33 months. There were four spontaneous and two induced abortions in the first trimenon. Ten women delivered ten healthy babies; three newborns had problems (alcoholic embryopathy due to recurrent alcohol abuse of his mother, pneumonia, weight < 2000 g). In eight women mostly mild complications were observed, such as hypertension (n = 5), nonspecific elevation of liver enzymes (n = 2), infection (n = 3) and premature labor (n = 1). Mean gestational age was 39 wk and mean birth weight 2900 g. One case of prematurity and three cases of growth retardation occurred. Cesarean sections were performed in 7 patients (54%) for maternal hypertension (n = 2), presumed fetal hypoxia (n = 4) and breech position (n = 1). All children are normally developed, the oldest being 5 yr old. Although experience with tacrolimus is limited, pregnancies following liver transplantation carry an acceptable risk if carefully monitored by an experienced team of transplant surgeons and obstetricians.

Docosahexaenoic acid (DHA) is essential for the growth and functional development of the brain in infants. DHA is also required for maintenance of normal brain function in adults. The inclusion of plentiful DHA in the diet improves learning ability, whereas deficiencies of DHA are associated with deficits in learning. DHA is taken up by the brain in preference to other fatty acids. The turnover of DHA in the brain is very fast, more so than is generally realized. The visual acuity of healthy, full-term, formula-fed infants is increased when their formula includes DHA. During the last 50 years, many infants have been fed formula diets lacking DHA and other omega-3 fatty acids. DHA deficiencies are associated with foetal alcohol syndrome, attention deficit hyperactivity disorder, cystic fibrosis, phenylketonuria, unipolar depression, aggressive hostility, and adrenoleukodystrophy. Decreases in DHA in the brain are associated with cognitive decline during aging and with onset of sporadic Alzheimer disease. The leading cause of death in western nations is cardiovascular disease. Epidemiological studies have shown a strong correlation between fish consumption and reduction in sudden death from myocardial infarction. The reduction is approximately 50% with 200 mg day(-1)of DHA from fish. DHA is the active component in fish. Not only does fish oil reduce triglycerides in the blood and decrease thrombosis, but it also prevents cardiac arrhythmias. The association of DHA deficiency with depression is the reason for the robust positive correlation between depression and myocardial infarction. Patients with cardiovascular disease or Type II diabetes are often advised to adopt a low-fat diet with a high proportion of carbohydrate. A study with women shows that this type of diet increases plasma triglycerides and the severity of Type II diabetes and coronary heart disease. DHA is present in fatty fish (salmon, tuna, mackerel) and mother's milk. DHA is present at low levels in meat and eggs, but is not usually present in infant formulas. EPA, another long-chain n-3 fatty acid, is also present in fatty fish. The shorter chain n-3 fatty acid, alpha-linolenic acid, is not converted very well to DHA in man. These longchain n-3 fatty acids (also known as omega-3 fatty acids) are now becoming available in some foods, especially infant formula and eggs in Europe and Japan. Fish oil decreases the proliferation of tumour cells, whereas arachidonic acid, a longchain n-6 fatty acid, increases their proliferation. These opposite effects are also seen with inflammation, particularly with rheumatoid arthritis, and with asthma. DHA has a positive effect on diseases such as hypertension, arthritis, atherosclerosis, depression, adult-onset diabetes mellitus, myocardial infarction, thrombosis, and some cancers.

Atherosclerosis is manifested as coronary artery disease (CAD), ischemic stroke and peripheral vascular disease. Moderate alcohol consumption has been associated with reduction of CAD complications. Apparently, red wine offers more benefits than any other kind of drinks, probably due to flavonoids. Alcohol alters lipoproteins and the coagulation system. The flavonoids induce vascular relaxation by mechanisms that are both dependent and independent of nitric oxide, inhibits many of the cellular reactions associated with atherosclerosis and inflammation, such as endothelial expression of vascular adhesion molecules and release of cytokines from polymorphonuclear leukocytes. Hypertension is also influenced by the alcohol intake. Thus, heavy alcohol intake is almost always associated with systemic hypertension, and hence shall be avoided. In individuals that ingest excess alcohol, there is higher risk of coronary occlusion, arrhythmias, hepatic cirrhosis, upper gastrointestinal cancers, fetal alcohol syndrome, murders, sex crimes, traffic and industrial accidents, robberies, and psychosis. Alcohol is no treatment for atherosclerosis; but it doesn't need to be prohibited for everyone. Thus moderate amounts of alcohol (1-2 drinks/day), especially red wine, may be allowed for those at risk for atherosclerosis complications.
