The prevalence of diabetes is known to be high in the West Indies, whereas CVD seems relatively rare. This apparently contradicts the existence of the insulin-resistance syndrome, a cluster of metabolic abnormalities supposedly favoring both diabetes and cardiovascular complications. To address the question of whether this contradiction could be accounted for by specific features of this syndrome, we compared 1505 Caucasian and 181 Afro-Caribbean men, all participants in the French Telecom Study. The Afro-Caribbeans were of the same age and had the same BMI as the Caucasians; they also had significantly higher subscapular skin-fold thickness and fasting insulin level, but similar BP and blood glucose level, and significantly lower plasma triglyceride level. Thus, although some features of the insulin-resistance syndrome were present (central adiposity and high insulin levels), none of the associated metabolic abnormalities were present. However, within the Afro-Caribbean group, subjects with plasma insulin concentrations above the median (> 52 pM) had higher mean BP and glucose and triglyceride levels compared with subjects with insulin concentrations < or = 52 pM (P < 0.001). After adjustment for age and BMI, these differences, though smaller, still were statistically significant. These findings confirm that higher insulin concentrations are associated with higher levels of potentially atherogenic and diabetogenic metabolic parameters. However, depending on ethnic origin, the mean levels of these parameters seem to be different, with the consequence that, even if they are elevated with increasing insulin levels, they may not reach values high enough to determine a substantial risk of disease.

The mortality rate and causes of death after a hip fracture were studied in 493 consecutive patients with a hip fracture. All patients were treated in three hospitals in Utrecht, The Netherlands. The mortality rate following hip fractures is high and age dependent. Forty-five patients, 38 women and 7 men, died during the period of hospitalization (9.1%). One year after the date of hip fracture 23.6% of the women had died and 33.0% of the men. Four years after the date of hip fracture the mortality rates in women and men were 44.4% and 55.3%, respectively. Male sex, concomitant illnesses and in-hospital complications are negative determinants of survival. The in-hospital mortality was due to: cerebrovascular accident (n = 7), cardiac decompensation (n = 12), myocardial infarction (n = 4), pulmonary infection (n = 6), intestinal bleeding (n = 1) and sepsis (n = 5). From the registration of death causes we learned that 54 deaths were directly due to the hip fracture, 4 due to bed sores, 34 due to infectious diseases, 62 due to cardiovascular disease, 22 due to cerebrovascular accidents, 14 due to diabetes mellitus, and 33 due to neoplasm. The high mortality rate within the first 8 weeks after the date of hip fracture was mainly attributed to the hip fracture.

Information concerning cardiovascular disease risk factors in Native American children is limited. In adult Native American populations, cardiovascular disease risk factors of non-insulin dependent diabetes mellitus, obesity, and cigarette smoking are prevalent, and recent reports indicate mortality caused by cardiovascular disease has dramatically increased. In a screening program at the Onondaga Nation School, six cardiovascular disease risk factors were evaluated. Of 95 school children, 55 representing 39 interrelated families, participated. Family histories were positive for diabetes mellitus in 72%, for cardiovascular disease in 54%, and for passive smoking in 90% of families. Physical examinations of the children revealed obesity (weight/height greater than 90th percentile) in 42% and hypertension (systolic or diastolic blood pressure/height greater than 95th percentile) in 22%. Fingerstick cholesterol levels (Reflotron system) were greater than 170 mg/dL in 25%. Overall, 85% of participants had three or more risk factors for cardiovascular disease. The study results indicate that Onondaga Native American children are at significant risk for cardiovascular disease; programs for identification and modification of cardiovascular disease risk factors are urgently needed.

Diabetic ketoacidosis remains a significant cause of death in cases of insulin-dependent diabetes mellitus (IDDM). Among patients hospitalised for diabetic ketoacidosis, the death rate is 5-10 per cent, cardiovascular disease, infection, and ARDS (adult respiratory distress syndrome) being major contributory factors, whereas the degree of acidosis does not differ from that among survivors. Ketoacidosis is a major determinant of the two-fold higher mortality among the youngest age-groups of IDDM patients. The age-specific incidence of ketoacidosis among patients under 20 years of age is several time higher than that among patients over 50. Intensified insulin treatment, using multiple injections or insulin pumps, probably results in an increased risk of insulin deficiency owing to the smaller insulin depots. Thus, there is a need of intensified testing for ketonuria and improved education of patients, physicians and other health care personnel, in order to promote the prevention or rapid, effective treatment of diabetic ketoacidosis.

Diabetic nephropathy is a common complication in diabetes mellitus. In addition to the risk of renal failure, patients with established nephropathy are at increased risk of proliferative retinopathy and cardiovascular disease. As the earliest prodrome of nephropathy is microalbuminuria, albumin excretion needs to be monitored with a reliable method in all diabetics. In the event of microalbuminuria, diabetes treatment needs to be intensified to optimise metabolic regulation. Early institution of antihypertensive treatment is essential to avoid progression to clinical nephropathy.

Although half of the American Indian population resides off the reservation, mostly in the western states, research on the health of urban American Indians remains sparse. American Indians living in urban areas are not eligible for the federally mandated health care provided by the Indian Health Service and receive health care services in a variety of settings. This population is at high risk for many health problems, especially cardiovascular disease and diabetes mellitus. Social, cultural, and economic barriers that impede access to health care for this group, particularly for elders living in an urban setting, could be reduced if physicians improved their understanding of and communication with American Indian patients.

The general concept of gene therapy is now well established and accepted by the medical, scientific and public policy communities, and is rapidly being implemented in human experimental studies. In addition to the initial models of single gene defects, target diseases have now come to include multigenic and multifactorial diseases such as human cancer, neurodegenerative diseases such as Parkinson's disease and firms of cardiovascular disease. While many conceptual and technical obstacles must still be overcome before therapy for disorders such as coronary artery disease and diabetes mellitus will easily be approached at the genetic level, the early results with several multigenic disease models gives some cause for optimism that gene therapies for even those complicated disorders will eventually become available.

Several epidemiological studies have shown that obesity is related to the mortality from cardiovascular disease. In this study, the epidemiology of obesity and the correlation between body mass index and other cardiovascular risk factors was studied in a representative sample of the adult population of Catalonia. It was obtained a random sample (n = 704) of the adult population of Catalonia aged 15 or more years. Height and weight were measured and body mass index (BMI) was calculated (height in Kg/weight2 in m2). Obesity was defined as a BMI greater than 30, and overweight as a BMI from 25 to 30. In the first 314 participants, it was determined the concentration of total cholesterol, cholesterol-HDL and triglyceride, and it was measured the blood pressure. The correlation between BMI and other cardiovascular risk factors was analysed. The study was carried out in 1989. The mean of BMI increased with age in both sexes. BMI was significantly higher in men (26 kg/m2) than women (25 kg/m2). The prevalence of obesity was of 12% in both men and women, and the prevalence of overweight was of 48.5% in men and 38% in women. The prevalence of arterial hypertension, hypercholesterolemia and diabetes was greater individuals with obesity, with differences statistically significant for hypertension (odds ratio of 3.26). The multiple logistic regression analysis showed that the association between obesity and hypertension was not statistically significant (OR adj. = 2.09), when the effect of the other risk factors, the age and sex were controlled.(ABSTRACT TRUNCATED AT 250 WORDS)

The role of waist-to-hip ratio (WHR) in the metabolic disturbance of IDDM has not been widely explored. Cross-sectional data from the Epidemiology of Diabetes Complications Study were used to examine the associations between WHR and risk factors for IDDM complications such as lipid or lipoprotein levels, blood pressure and fibrinogen. A total of 586 adults (greater than or equal to 18 years of age) were examined. WHR was calculated as the mean of duplicate waist circumference measurements made at mid-point between the iliac crest and the lower costal margin in mid-axillary line divided by the mean of duplicate maximum hip measures. WHR was positively correlated with total cholesterol, LDL-cholesterol, triglycerides, systolic and diastolic blood pressure and fibrinogen univariately for both sexes. WHR was negatively correlated with HDL-cholesterol. These correlations remained significant after adjustment for age among females and became less strong, although still significant, for males. The independent effects of WHR to these IDDM risk factors, assessed by multiple linear regression, indicated WHR was related to adverse lipid and lipoprotein levels, but not to fibrinogen or blood pressure. These findings underscore the importance of targeting intervention to IDDM individuals who have a high WHR to reduce known risk factors for IDDM complications especially those for cardiovascular disease, and is consistent with the hypothesis that insulin resistance may have a role to play in IDDM complications.

Obesity is a major risk factor for cardiovascular disease. However, a direct link between these two states is difficult to establish, since obesity frequently occurs with other disease states such as diabetes, hypertension and atherosclerosis. Clinical studies have clearly shown that uncorrected obesity is associated with cardiac hypertrophy and compromised ventricular function. A number of rodent models of obesity have been studied in terms of cardiovascular adaptations. Cardiac function of the obese Zucker rat appears to be normal at a younger age. Only after several months is depression in cardiac function discernable. These animals are mildly hypertensive, but do not exhibit the characteristic increase in cardiac output associated with human obesity. A unique characteristic of JCR:LA-cp rat is that they develop atherosclerotic and myocardial lesions. Hearts from these animals will maintain normal function when perfused with physiological levels of calcium. At higher calcium concentrations, however, mechanical function becomes impaired. Dietary-induced obese rats exhibit many of the hemodynamic alterations associated with human obesity, but there is no evidence to-date that these animals will develop severe cardiac depression. Short-term weight reduction apparently has beneficial cardiovascular effects, but weight cycling may be harmful. Given the widespread occurrence of obesity, further studies are warranted to characterize the cardiac manifestations of this condition.
