question:
Little is known about endothelial function in adolescents with type 1 diabetes, and we evaluated endothelial dysfunction, using reactive hyperaemia peripheral arterial tonometry (RH-PAT).', 'This prospective, observational, 1-year study focused on 73 adolescents with type 1 diabetes, using multiple daily injections or continuous subcutaneous insulin infusion. The subjects were assessed using RH-PAT, body mass index, blood pressure, fasting lipid profile, glycated haemoglobin, insulin requirements and hours of physical exercise per week.', 'Endothelial dysfunction was observed in 56 patients (76.7%), with lower mean RH-PAT scores (1.26\xa0±\xa00.22 versus 2.24\xa0±\xa00.48, p\xa0<\xa00.0001) and higher glycated haemoglobin values at baseline (8.27\xa0±\xa01.24% versus 7.37\xa0±\xa00.54%, p\xa0=\xa00.006) and as a mean of the whole period since diagnosis (8.25\xa0±\xa01.22% versus 7.72\xa0±\xa00.82%, p\xa0=\xa00.034). A higher percentage of patients with endothelial dysfunction showed abnormal cardiac autonomic tests (p\xa0=\xa00.02) and were more sedentary, exercising <4 hours a week, than patients with normal endothelial function. After follow-up in 64/73 patients, we observed endothelial dysfunction in 81.8% of patients, despite a modest improvement in glycated haemoglobin.

1


question:
The appropriateness of vigorous fluid resuscitation to normal blood pressure following hemorrhage in uncontrolled bleeding has recently been questioned due to the possibility of dislodging clots and exacerbating hemorrhage. To develop a rational blood pressure target that maximizes the metabolic benefits of resuscitation without causing increased blood loss, it was first necessary to determine whether there is a reproducible mean arterial pressure (MAP) at which rebleeding occurs. The purpose of this study was to explore the relationship between the rate and time of resuscitation after injury and the rebleeding MAP in an uncontrolled hemorrhage model.', "Sixty-two anesthetized pigs were instrumented with catheters and splenectomized, and suction tubes were placed in the lateral peritoneal recesses to continuously capture shed blood. With the abdomen open, an aortotomy was made in the infrarenal aorta. At either 5, 15, or 30 minutes after the end of the initial hemorrhage, resuscitation with warmed lactated Ringer's solution was begun at either 100 or 300 mL/min. The rebleeding MAP was determined at the moment blood appeared in the suction tubes.", 'The average pressure at the rebleeding point for all animals was MAP = 64 +/- 2, Systolic = 94 +/- 3, and Diastolic = 45 +/- 2 mm Hg. The pressure at which rebleeding occurred in this aortotomy model was not affected by either time of resuscitation (5-30 min), nor was the rebleeding pressure affected by the rate (100 vs. 300 mL/min) of resuscitation.

question:
Diabetes, arterial hypertension, hypercholesterolemia, and aging are associated with endothelial dysfunction in various vasculatures. Endothelium-dependent vasodilation of the renal vasculature cannot be easily assessed, but infusion of L-arginine, the substrate of endothelial nitric oxide synthase, leads to an increase in renal plasma flow (RPF) in humans. We have examined the effect of L-arginine infusion on renal hemodynamics in hypertensive patients with type 2 diabetes.', 'Twenty-three elderly patients with type 2 diabetes (age, 65 +/- 6 years; HbA(1c), 7.8 +/- 1.6%) with coexisting arterial hypertension (158 +/- 19/83 +/- 11 mmHg) and elevated cholesterol levels (total cholesterol, 215 +/- 33 mg/dl) were examined. These patients were compared with a young and healthy reference group (n = 20; age, 26 +/- 2 years). The effect of L-arginine infusion (100 mg/kg over 30 min) on RPF and glomerular filtration rate were measured using the constant input clearance technique with p-aminohippurate and inulin, respectively.', 'L-arginine infusion similarly influenced renal hemodynamics in patients and reference subjects: RPF increased by 7 +/- 11 and 7 +/- 11% in diabetic and reference subjects, respectively (P = NS). Other parameters of renal hemodynamics such as glomerular filtration rate (5 +/- 5 vs. 4 +/- 4%) and filtration fraction (-1 +/- 8 vs. -1 +/- 9%) were not significantly different between diabetic and reference subjects, too.
