Clinical performance of CGMS in type 1 diabetic patients treated by continuous subcutaneous insulin infusion using insulin analogs.

Objective: Performance criteria have been established for in vitro blood glucose monitoring, particularly for the self-monitoring of blood glucose using glucose meters. Devices intended for use in the future, such as the continuous glucose monitoring system (CGMS), should satisfy similar criteria, particularly in diabetic patients under intensive therapy.

Research Design And Methods: The analysis was conducted on 18 type 1 diabetic patients (not controlled, HbA(1c) >7.

Environmental and genetic determinants of intima-media thickness of the carotid artery.

1. The aim of the present study was to investigate carotid intima-media thickness (CIMT) in relation to anthropometric, environmental and genetic factors, as well as cholesterol and blood pressure levels. 2.

Treatment of congestive heart failure: interfering the aldosterone-cardiac extracellular matrix relationship.

Cardiac extracellular matrix undergoes extensive and continuous turnover involved in the lesion-reparation process, such as in cardiac remodeling, in hypertensive cardiac hypertrophy, in dilated cardiomyopathy, after myocardial infarction in the transition to heart failure, and during the progression of left ventricular dysfunction. Cardiac fibrosis is a major determinant of diastolic dysfunction and pumping capacity, and it may provide the structural substrate for arrhythmogenicity, thus potentially contributing the to progression of heart failure and sudden death. Aldosterone was shown to promote cardiac fibrosis in various experimental models.

The potential advantages of a modern antihypertensive therapy in the elderly.

More than 50% of hypertensive patients are aged above 65 years. Physiopathology of essential hypertension is different in the elderly as compared with the young adult. Furthermore, not only are concomitant diseases statistically more frequent in the elderly, but the aging process in itself produces several specific changes in target organs.

Limitation of excessive extracellular matrix turnover may contribute to survival benefit of spironolactone therapy in patients with congestive heart failure: insights from the randomized aldactone evaluation study (RALES). Rales Investigators.

Background: In congestive heart failure (CHF), extracellular matrix turnover is a major determinant of cardiac remodeling. It has been suggested that spironolactone may decrease cardiac fibrosis. We investigated the interactions between serum markers of cardiac fibrosis and the effect of spironolactone on outcome in patients with CHF.

Diamicron MR once daily is effective and well tolerated in type 2 diabetes: a double-blind, randomized, multinational study.

In a double-blind, multicenter, multinational study, the long-term efficacy and safety of Diamicron(R)MR, a new gliclazide formulation taken once daily at lower dose (30-120 mg/day) was compared with Diamicron(R) (80-320 mg/day) taken twice daily in type 2 diabetic outpatients. After a 2-week run-in period, 800 patients with poor blood glucose control were randomized to Diamicron(R)MR (n=401) or Diamicron(R) (n=399). After a 4-month titration period, the efficacy and safety of Diamicron(R)MR was compared with Diamicron(R) over a 6-month fixed-dose treatment period.

Differential effects of aging on heart rate variability and blood pressure variability.

Previous studies investigating autonomic cardiovascular control in elderly persons usually included analysis of R-R interval but not of blood pressure variability. "Physiological" blood pressure rise during the aging process was not accounted for as a possible confounding factor. This study was designed to characterize the relationship between age and short-term heart rate (HR) and blood pressure (BP) variability, independently of the "physiological" rise in BP associated to aging.

Shear stress abnormalities contribute to endothelial dysfunction in hypertension but not in type II diabetes.

Background: The relative contribution of the various hemodynamic and metabolic mechanisms leading to endothelial dysfunction may be different in specific vascular diseases. Since shear stress is one of the main mechanical stimuli of endothelial cells, the aim of this study was to investigate its contribution to endothelial dysfunction in two distinct vascular diseases, hypertension and type II diabetes.

Subjects And Methods: We measured the radial artery diameter at baseline, after ischemic vasodilation and after nitroglycerin vasodilation in 16 untreated patients with high blood pressure, in 15 type II normotensive diabetic patients and in 17 healthy controls.

Differential effects of fosinopril and enalapril in patients with mild to moderate chronic heart failure. Fosinopril in Heart Failure Study Investigators.

Objectives: To investigate the efficacy and safety of fosinopril in the treatment of chronic heart failure (CHF), patients with mild to moderate CHF and left ventricular ejection fractions <40% were randomly assigned in a double-blind manner to receive fosinopril 5 to 20 mg every day (n = 122) or enalapril 5 to 20 mg every day (n = 132) for 1 year.

Results: The event-free survival time was longer (1.6 vs 1.

Genetics strongly determines the wall thickness of the left and right carotid arteries.

In 76 supposedly healthy families, we investigated the familial resemblance of left and right carotid intima-media thickness (IMT) measured by B-mode ultrasonography and the impact of the common apolipoprotein E (apo E) polymorphism and the insertion/deletion polymorphism of the angiotensin-converting enzyme (ACE). Genetic factors accounted for about 30% of IMT variation. The insertion/deletion ACE polymorphism did not influence carotid IMT, whereas apoE polymorphism explained about 1.

Blood glucose control on Sunday in IDDM patients: intensified conventional insulin therapy versus continuous subcutaneous insulin infusion.

We have assessed the capacity of continuous subcutaneous insulin infusion (CSII) to maintain good blood glucose metabolic control on Sundays, when waking is delayed, with reference to intensified conventional insulin therapy by multiple daily injections (MDI). The study lasted 3 weeks, including 3 week-ends. A total of 20 IDDM patients were selected for metabolic control: ten were treated by CSII and ten by MDI.
