1496 women age 55 to 74 were studied in an effort to determine heart disease risk factor differences attributed to postmenopausal estrogen (PME) use. 39% of the females reported using estrogen at the time of the study, with peak hormone use in the 55 to 59 year age group. Analysis of the following possible confounding variables, social class, current cigarette smoking, family history of heart attack or diabetes and obesity found that only obesity was statistically significant ( P .001) and thus further analysis of PME use was adjusted for obesity. Results showed average cholesterol level was 9.4 to 20.4 mg/dL lower among PME users compared to nonusers. Although triglyceride level was higher in PME users at all ages it was only statistically significant for women aged 60-69 years. Mean systolic and diastolic blood pressures were 2 to 4 mm Hg lower in PME users and the average fasting plasma glucose level was significantly lower in young PME users only. Multivariate Hotellings T statistic was used to test for independence. While the study examined the net cumulative effect of PME use of putative heart disease, it did not examine specific estrogens, dosage or duration of use differences. The authors concluded that further studies are needed before final conclusions can be made regarding the use of PME as a risk factor reducer in heart disease.

We have made a non-selective search for patients undergoing treatment for more than five years for an arterial deficiency of the lower limbs. Most of the patients studied suffered from intermittent claudications for which surgical treatment was impossible (distal lesions, diabetes, coronaritis) or had failed (sympathectomy, recurrences). Faced with the inefficiency of vasodilators, and in addition to strict medical treatment of the risks factors of arterio-sclerosis disease (tobacco, obesity, hypercholesterol, sedentary habits), we treated these patients using intra-arterial injections according to the method of Reboul. Our patients generally received one injection per week of xylocaine-priscol-pronestyl. Once an improvement appeared, these injections were spaced out so as to become semi-annual. We grouped 67 patients suffering from intermittent claudications and 5 patients suffering from arteritis ulcers. We studied the results obtained from this so-called palliative treatment (the claudication going from an average 201 meters to 3,395 meters after five years and cure of the ulcers).

Blood glucose levels were studied prospectively in 40 patients undergoing elective major craniotomy. A significant (p less than 0.01) hyperglycaemic response was noted after scalp infiltration with adrenaline and incision (0.5 mmol/l) and with continued surgery (0.9 mmol/l). Patients aged 50 years and under showed a significantly greater rise with adrenaline and incision than older patients (0.8 compared with 0.4 mmol/l p less than 0.01). Preoperative high dose steroid therapy did not modify the response. Blood glucose changes were unrelated to sex, obesity, a family history of diabetes, the duration of starvation, intraoperative body temperature, anaesthetic technique, induced hypotension or blood loss.

To study the role of nutritional factors in the genesis of diabetes, estimations of blood sugar concentration, food intake, and adiposity (as body mass index; BMI) were carried out on three normal population samples--namely, 961 employees of Beecham Ltd, 1005 employees of the Greater London Council, and 1488 middle-aged male civil servants (Whitehall study). Blood sugar concentrations and indices of glucose tolerance correlated positively with the degree of adiposity but tended to be negatively correlated with total food energy intake and its component nutrients (total carbohydrate, sucrose, and fat). This inverse trend was largely accounted for by highly significant inverse correlations between food energy intake and adiposity, a relation found in both sexes and in all three population samples and which extended across the whole range of nutrient intake and BMI. These findings suggest that greater degrees of adiposity are associated with lower than average food energy intakes and hence lower total energy expenditures. The association of increased adiposity with low food energy consumption may indicate an underlying "low energy throughput" state, and it may be the mechanisms of this, as well as the obesity, that are responsible for disease.

In an attempt to determine whether the decreased number of insulin's receptors in obesity is a result of downregulation of the receptors, diazoxide (5 mg/kg/d) was given to 10 obese subjects. Insulin's suppression by diazoxide in these 10 subjects resulted in a mild glucose intolerance and an increase in insulin's receptors in seven of the 10 subjects. The subjects could be divided into three groups by analyzing the Scatchard plots of their insulin receptor studies before and after diazoxide. Four subjects exhibited an increase in both high affinity and low affinity receptors, three showed an increase only in high affinity receptors, and three failed to demonstrate any change in receptors in response to diazoxide. These studies support the concept that the decreased number of insulin's receptors observed in obesity is a result of the downregulation of the receptors and is not the primary, underlying cause of insulin resistance in obesity, although a contributory role cannot be ruled out.

The effect of a new complex oligosaccharide (Bay g 5421) of microbial origin on human intestinal alpha-glucosidehydrolase activity was tested in mucosal homogenate from human small bowel biopsy specimens. The alpha-glucosidehydrolase inhibitor (alpha-GHI) exerted a potent inhibitory effect on glucoamylase, sucrase, and maltase, was minimally effective on isomaltase, and did not affect trehalase and lactase activity. Kinetic analysis revealed a fully competitive type of inhibition with a Ki of 1.3 x 10(-6) M; thus the inhibitor had a 15,000-fold higher affinity to the enzyme sucrase than its natural substrate sucrose. The new compound may prove to be useful in the study of carbohydrate maldigestion and malabsorption and may possibly be of therapeutic benefit in diabetes and obesity.

Some lipid and lipoprotein accompaniments of obesity and its association with glucose intolerance are examined in the Framingham cohort of 5209 men and women ages 30 to 59 examined biennially over 18 years. While beta and pre-beta lipoproteins were positively correlated with relative weight, high density lipoprotein cholesterol was inversely correlated. The association was strongest for high density lipoprotein cholesterol, varying little by age and sex. Triglyceride was a close second, but unlike high density lipoproteins, it and other lipids were more closely associated with obesity in men than women and in younger than older persons. Obese persons tended to have a greater likelihood of glycosuria and an increasing prevalence of diabetes. Relative weight in the Framingham cohort rose in both sexes to age 54, remained essentially unchanged until age 62 and then began to decline. Despite such changes body weights even 18 years apart had a correlation of 0.8. Men from each succeeding birth cohort were heavier, women were lighter, but even women from the most recent birth cohort were much more frequently above "desirable" weight than below it.

Dietary data was obtained from 77 adult Micronesian (Nauruan) subjects during a diabetes epidemiological survey. The life-style of this isolated Pacific population is almost completely Westernized and they have been shown to have a very high diabetes prevalence rate. Nearly all food consumed by the islanders is imported from Australia. The main caloric intake of both males and females was at least twice those recommended for Western or developing Pacific populations. The diet meets or exceeds the Australian National Health and Medical Research Council recommended allowance for calories, protein, fat, and ascorbic acid, but thiamin intake was inadequate. The percentage of fat in the diet was lower than that consumer by Western populations. Obesity is a pronounced feature of this population and the high caloric intake coupled with reduced physical activity would appear to be a major factor in relation to this. This Micronesian group has a genetic susceptibility to diabetes which may have been unmasked by the change from traditional to Western life-style. This problem may not be unique to Nauru and, with progressive Westernization, many other Polynesian and Micronesian populations may be at risk.

An optimal diet cannot yet be defined. If we knew what an optimal diet was, additional research in nutrition would not be necessary. There is abundant evidence, however, that the usual American diet is not optimal and adequate reason to recommend modification. Current dietary recommendations were developed to prevent the occurrence of nutritional deficiency disease in the 1930's and 1940's. They have been largely successful. They were made, however, before any knowledge was available about the effects of diet upon chronic disease which now represent the primary health problems of the United States. Large amounts of data are available indicating the kids of recommendations which should be made to control hypercholesterolemia--a primary risk factor of coronary artery disease. These kinds of data together with less information upon diet and cancer, hypertension, obesity, diabetes, etc. lead to sensible and consistent dietary recommendations to moderate the dietary practices of most Americans.

The characteristics of the glucose and insulin responses during the glucose tolerance test (GTT) in obese people as a group have not been established. We analyzed glucose and insulin levels during GTT in 160 healthy obese patients who averaged 42% over ideal body weight. Statistical upper limit of normal for 2-h glucose was 260 mg/dl in women and 206 mg/dl in men. Although there was a significant correlation between insulin and glucose levels in both sexes and between insulin and degree of obesity in women, r values were relatively low (r less than 0.4 for all). High insulin levels and delayed peak insulin were present in the majority of patients with normal GTT and absent in many of the most obese patients. Results indicate that upper limits of normal glucose for GTT in the obese are much higher than currently accepted criteria.
