Minimal explicit consensus criteria in the management of patients with four indicator conditions were established by an ad hoc committee of primary care physicians practicing in different locations. These criteria were then applied to the practices of primary care physicians located in a single community by abstracting medical records and obtaining questionnaire data about patients with the indicator conditions. A standardized management score for each physician was used as the dependent variable in stepwise regression analysis with physician/practice and patient/disease characteristics as the candidate independent variables. For all physicians combined, the mean management scores were high, ranging from .78 to .93 for the four conditions. For two of the conditions, care of the normal infant and pregnant woman, the management scores were better for pediatricians and obstetricians respectively than for family physicians. For the other two conditions,
adult onset diabetes
and congestive heart failure, there were no differences between the management scores of family physicians and internists. Patient/disease characteristics did not contribute significantly to explaining the variation in the standardized management scores.

We investigated a family in which at least 4 men in 3 generations had a syndrome of obesity, mild mental retardation, delayed puberty, macroorchidism, acanthosis nigricans, hyperinsulinemia, and later overt insulin-resistant diabetes mellitus (non-insulin-dependent diabetes mellitus,
NIDDM
). The patients have markedly curly scalp hair, deficient face and body hair. Their teeth were healthy and normal in size and position. The clinical and biochemical findings and characteristics of the insulin receptors investigated in fibroblasts are reported. There was normal insulin binding to fibroblasts in the 2 brothers and their father. However, insulin-stimulated RNA synthesis was decreased as compared to that of normal control individuals. These findings suggest a postbinding defect of insulin action. The pedigree documents an autosomal dominant mode of inheritance. The diagnosis is of practical importance since it enables medical supervision of gene carriers in a preclinical state of atherosclerotic complications and overt diabetes. The findings in this family have relevance also to the explanation of familial mild mental retardation and to the study of different forms of insulin resistance due to a disturbance in biosignal transfer.

High-performance liquid chromatographic (HPLC) analysis of human serum albumin (HSA) on Asahipak GS-520H columns at neutral pH (6.87) showed a clear resolution of human mercaptalbumin (HMA) and nonmercaptalbumin (HNA), which are reduced and oxidized form of HSA, respectively. We studied the conversion of HMA to HNA (mercapt-nonmercapt conversion) as an index of oxidative change of the tissues and organs in 28 normal subjects and in a total of 47 patients with
non-insulin dependent diabetes mellitus
(
NIDDM
). Mean (+/- SD) values of the HMA fraction of HSA, f(HMA), [HMA/(HMA + HNA)], was significantly lower in
NIDDM
patients than in normal subjects (0.63 +/- 0.067 vs 0.75 +/- 0.028, P < 0.001). It was lower in poorly controlled
NIDDM
patients (0.63 +/- 0.058, n = 20) than in well controlled
NIDDM
patients (0.67 +/- 0.032, n = 9) (P < 0.05). Plasma glucose values sampled on occasions including overnight fasting and postprandial ones (r = -0.441, n = 47, P < 0.01), but not plasma glucose values sampled on overnight fasting (r = -0.345, n = 29) or postprandial (r = -0.467, n = 18) conditions and HbA1c (r = -0.211, n = 34), negatively correlated with the f(HMA) values, indicating that mercapt-nonmercapt conversion may not be due to cumulative hyperglycemia over a month, but due to short-term alteration in blood glucose level. The presence or absence of diabetic complications including nephropathy, retinopathy and neuropathy did not affect the f(HMA) values. In conclusion, decreased f(HMA) values in the diabetic patients suggested the presence of a rapidly altered oxidative change of albumin due to hyperglycemia.

Changes in urine retinol binding protein (RBP, M(r) 21,000) excretion and other indices of renal tubular damage were investigated in the patients with
non-insulin dependent diabetes mellitus
(
NIDDM
). Changes in urine RBP excretion were well paralleled with those of urine NAG excretion. In RBP-negative patients, the subjects with hypertension (systolic blood pressure > or = 140 mmHg or diastolic blood pressure > or = 90 mmHg) showed higher beta 2-microglobulin (beta 2-MG) excretion and albumin (Alb)/Cr ratios than normotensive ones. In addition, both urine beta 2-MG excretions and Alb/Cr ratios were significantly increased in RBP-positive patients. The measurement of urine RBP excretion may have an additional role in the diagnosis of renal tubular dysfunction in diabetic patients.

Recently, human amniotic fluid (HAF) from healthy women was found to stimulate growth and function of pancreatic B-cells. Here, the effect of HAF and serum from healthy probands (HS) was compared with that from probands with gestational (GD), noninsulin-dependent (
NIDDM
), or insulin-dependent diabetes (IDDM) on islet function and replication. Rat islets were cultured in the presence of either HAF or HS for 7 d. Insulin content and basal insulin release were not different after exposure of the islets to HAF or HS from healthy or diabetic women. In contrast to HS, HAF provoked the islets to deliver significantly more insulin during culture. Additionally, the same islets exhibited a more intense response to a glucose challenge. The degree of HAF-induced insulin release was not influenced by the type of diabetes. HAF and HS from GD and
NIDDM
women did not influence the islet DNA synthesis in comparison to HAF and HS from healthy pregnant women. However, HAF but not HS from IDDM pregnant women, elicited a significant increase in islet replication. Most effective in stimulating islet cell replication were HAFs from IDDM pregnant women belonging to the White D-type. It was shown that the relatively high concentration of insulin in the HAFs was not directly responsible for the observed increase of the islet DNA synthesis. HAF from women with long-term diabetes is supposed to contain factor(s) that might directly or indirectly enhance islet replication.

The purpose of this study was to determine the association of the prevalence of non-insulin-dependent diabetes (
NIDDM
) with central obesity, obesity, and family history of diabetes. This survey consisted of 1590 subjects (646 men, 944 women) aged 30 years or more from the Sun-Ming district of Kaoshiung city. Glucose tolerance status was ascertained by both medical history and a 75-g oral glucose tolerance test according to World Health Organization criteria. In men and women with central obesity (WHR > or = 0.92 in men and > or = 0.85 in women) or obesity (BMI > or = 27.6 kg/m2 in men and > or = 28.3 kg/m2 in women) (WHR: waist-hip ratio; BMI: body mass index), the prevalence of impaired glucose tolerance (IGT) and diabetes was significantly higher, except the prevalence of diabetes in both sexes with obesity and the prevalence of IGT in women with central obesity were not statistically different, as compared with nonobese subjects. The prevalence of diabetes in men significantly increased from the first quartile to the fourth quartile of BMI and the waist-hip ratio (WHR) (4.48% to 9.21% in BMI, 3.67% to 13.61% in WHR), while the prevalence in women also significantly increased from the first to fourth quartile (2.45% to 11.76% in BMI, 2.04% to 13.49% in WHR). Multiple logistic regression analyses revealed similar increase in the prevalence of diabetes among both men and women for every 1 kg/m2 increase in BMI and every 0.05 increase in WHR (1.07-fold and 1.09-fold in BMI, 1.34-fold and 1.32-fold in WHR, respectively).(ABSTRACT TRUNCATED AT 250 WORDS)

Basal serum growth hormone and response of GH to GRF in 10 patients with noninsulin-dependent diabetes and in 10 control subjects were studied. The basal GH level in
NIDDM
was higher than that in control subjects. There was a significant difference. After an intravenous bolus of hGRF 1-29 NH2 with the dose of 1 microgram/kg body weight, GH (Peak level-basal level) decreased in
NIDDM
patients in comparing with control group (P < 0.05). These findings may suggest that the pituitary GH reserve is reduced in patients with
NIDDM
. There exists some defect in central GH control in diabetics with enhanced somatostatin secretion and abnormal sensitivity of the GH secretion cells to a variety of regulatory factors including GRF, glucose, amino-acids, free fat acid.

Abdominal obesity is closely associated with risk factors for cardiocerebrovascular disease and
NIDDM
and the precipitation of these diseases. Together, they seem to constitute a metabolic syndrome where hyperinsulinaemia, insulin resistance, hyperlipidaemia, hypertension, visceral fat accumulation, cardiocerebrovascular disease and
NIDDM
are the individual constituents. The background to this syndrome might be a primary aberration expressing itself as an increased sensitivity of the hypothalamo-adrenal axis, and subsequent inhibition of sex steroid hormone secretions. This in turn will probably be followed by metabolic derangements, primarily peripheral insulin resistance, as well as by visceral fat accumulation by mechanisms which are partially visualized by recent work in the field. Visceral fat accumulation may then amplify the metabolic aberrations via hepatic effects of excessive concentrations of portal FFA, producing hyperproteinaemia, hyperglycaemia, hyperinsulinaemia and, perhaps, hypertension. The background to the central endocrine aberration remains more speculative, but factors leading to increased cortisol production, including specific stress reactions, tobacco smoking and alcohol may turn out to be important. The tentative conclusion provides a hypothesis for further work, and has recently obtained considerable support from further observations in humans in other than the endocrine and metabolic areas, as well as from studies in experimental animal models, where such factors can be studied under fully controlled conditions, which is not possible in humans for ethical reasons.

The obvious syntropy of obesity and type II (non-insulin dependent) diabetes mellitus has always suggested a causal inter-relationship between the two diseases. However, the actual pathophysiological connection still remains to be elucidated. Recent findings have suggested that insulin resistance and hyperinsulinaemia might link glucose intolerance/
type II diabetes mellitus
, hypertension and hyperlipoproteinaemia in the context of a hypothetical 'syndrome X' characterized by an excessive risk constellation for the development of atherosclerosis. However, as to the practical consequences of the ('diabesity') syndrome of
type II diabetes mellitus
and structured programmes for effective therapy, very little new information has been gathered during the past 100 years.

Insulin resistance contributes to the metabolic defects in
non-insulin dependent diabetes mellitus
(
NIDDM
). Anorectic agents have been shown to improve insulin action in
NIDDM
, irrespective of weight reduction. In a double-blind placebo-controlled cross-over study, we examined hepatic and peripheral insulin action by the sequential hyperinsulinaemic-euglycaemic clamp technique with infusion of 3-[3H]-glucose in eight obese
NIDDM
patients and in eight obese non-diabetics, matched for age, sex and body mass index. Body weight was kept constant. After 14 days of fluoxetine, 60 mg daily, in
NIDDM
half-maximal peripheral glucose uptake was achieved at a lower insulin level than after placebo (ED50pgu: 180.5 +/- 25.8 vs. 225.3 +/- 39.9 mU/l, P < 0.05), but not in non-diabetics (140 +/- 15.3 vs. 135.3 +/- 22.2 mU/l, n.s.). Maximal peripheral glucose uptake (Vmaxpgu) did not change significantly. Multivariate analysis disclosed no differences in the effect of fluoxetine between
NIDDM
and non-diabetics. When non-diabetics and
NIDDM
were considered together, only the most insulin-resistant individuals demonstrated a decrease in ED50pgu (P < 0.001). Likewise, only the individuals with the most outspoken hepatic insulin resistance demonstrated a decrease in insulin level, at which hepatic glucose production (HGP) is completely suppressed (HGP0) (P < 0.01). In conclusion, fluoxetine improves peripheral and hepatic insulin action in obese insulin-resistant subjects irrespective of its weight lowering effect.
