[Vascular risk factors in non-insulin-dependent diabetes mellitus. Correlation between albuminuria and glycosylated hemoglobin].

OBJECTIVE: This study compared 23 patients with non-insulin-dependent diabetes mellitus (NIDDM) and 28 non-diabetic control subjects, seeking for associations between NIDDM and other cardiovascular risk factors. The relationship of the glycemic control with the risk factor profile was also assessed. RESULTS: The most outstanding results were: The diabetic group showed higher values in the proportion of subjects with diabetes family history (P < 0.01) and the levels of systolic blood pressure (P < 0.05), total cholesterol (P < 0.05), triglyceridemia (P < 0.001), and total cholesterol to HDL cholesterol ratio (P < 0.01). Within the diabetic group, a positive correlation (r = 0.68, P < 0.001) was found between the percent of glycosylated haemoglobin (HbA1c) and the 24-hour urinary albumin excretion rate (UAER). CONCLUSION: We conclude that NIDDM associates to other cardiovascular risk factors. The correlation of HbA1c with UAER suggests a possible relationship between poor diabetic control and some of the secondary diabetic complications.

Relation between flight hours and peripheral nervous conduction velocity.

The peripheral nervous system is highly sensitive to variations in the internal medium. A neurophysiological study (peripheral nervous conduction velocity) and an enzymatic study (catalase and glutathione-peroxidase) were performed in both instructor and student pilots. Pilots do not show the age-dependent decrease in the peripheral sensory nervous conduction velocity observed in non-pilot subject controls. The sensory conduction velocity (SCV) was significantly (p less than 0.01) increased when hours of flight experience increased, yielding a positive correlation (r = 0.6461; p = 0.0016). A significant (p less than 0.01) increase in the erythrocite catalase and glutathione-peroxidase activities were observed in pilots vs. controls. The present data suggest that a chronically increased oxygen consumption could be the reason for the increase in peripheral nervous conduction velocity observed in pilots.
