OBJECTIVE To evaluate through early preclinical atherosclerosis assessment whether repeated episodes of hypoglycemia represent an aggravating factor for macrovascular disease in type 1 diabetes. RESEARCH DESIGN AND METHODS After sample-size calculation, a case-control study of 25 patients with type 1 diabetes and repeated severe/nonsevere hypoglycemia(More)
The biological basis of the association between cannabis-induced dopamine dysregulation and psychosis remains poorly understood. This (123)I-IBZM SPECT study assessed striatal dopamine D2 receptor (D2R) binding in 37 untreated first-episode psychosis (FEP) subjects, and 18 healthy controls. The aim was to examine if there were differences between FEP(More)
There is as yet no definite prognostic marker to determine whether a first-episode psychosis will become schizophrenia or not. The aim of the present study is to address whether the mechanism of sensitization of the subcortical dopaminergic pathway - yielding to an increase of the postsynaptic D2 receptors - may serve as a prognostic marker of clinical(More)
Levels above 75% of striatal dopamine 2 receptor occupancy (D2RO) have been associated with extrapyramidal symptoms (EPS). The aim of the present study is to investigate the relationship between D2RO and EPS in a sample of psychotic patients in current treatment with both typical and atypical antipsychotics.
