Filter by:The aim of this study was to assess the clinical performance of two different ke0s (fast and slow) in terms of propofol effect-site concentration (Ce) during the loss and recovery of consciousness, using Marsh's pharmacokinetic model.The hypothesis to be tested was that the Ce of propofol predicted by the slow ke0 in the loss and recovery of consciousness is similar, differently from the fast ke0.
The aim of the study is to compare a multidisciplinary examination and follow up by rehabilitation program with a multidisciplinary examination, good advice and follow up by the family doctor. Further on we will examine if there were differing clinical characteristics between patients who attended a planned follow-up session and those that failed to and Prognostic factors in mild traumatic brain injury patients after discharge from hospital.
The purpose of this study is to determine whether islet transplantation alters brain glucose concentrations in patients with type 1 diabetes, recurrent hypoglycemia, and hypoglycemia unawareness when compared to that measured prior to transplant in the same subjects.
Hypoglycaemia unawareness is a common complication in patients with type 1 diabetes and with insulin-treated type 2 diabetes of long duration. The loss of autonomic symptoms to hypoglycemia does not solely depend on loss of adrenaline responses.Differences in sensitivity to catecholamines may also be involved. Reconciling the data on β2-adrenergic receptor polymorphism to those on loss of β-adrenergic sensitivity in diabetic patients with hypoglycemia unawareness, we hypothesize that hypoglycemia unawareness is at least partly the result of desensitization of the β2-adrenergic receptor and that patients who are homozygous for arginine at codon 16 are particularly susceptible for this desensitization process, whereas patients who are homozygous for glycine at codon 16 are resistant for desensitization. Objectives 1. To determine whether, and if so to what extent, antecedent hypoglycemia reduces β2-adrenergic sensitivity in healthy subjects with Arg16 homozygosity. 2. To investigate whether or not healthy subjects with Gly16 homozygosity are resistant to desensitization 3. To confirm that antecedent hypoglycemia reduces the heart rate response to isoproterenol and to assess to what extent this reduced response is mediated by impairments in baroreflex sensitivity.
