AIM There are conflicting data regarding the risk of osteoporosis in patients with Type 1 diabetes. We investigated an association between diabetes, bone mineral density and prevalent fractures. METHODS A single-centre, cross-sectional study of men and pre-menopausal women with Type 1 diabetes (n = 128) and a matched control group (n = 77) was conducted.(More)
Fracture risk in type 1 diabetes (T1D) is supposed to be underestimated by bone mineral density (BMD). Individuals with T1D had more prevalent fractures in a cross-sectional study. Serum levels of pentosidine, an advanced glycation end product, and poor glycaemic control were associated with prevalent fractures independent of BMD. Type 1 diabetes (T1D) is(More)
Trabecular bone score (TBS) seems to provide additive value on BMD to identify individuals with prevalent fractures in T1D. TBS did not significantly differ between T1D patients and healthy controls, but TBS and HbA1c were independently associated with prevalent fractures in T1D. A TBS cutoff <1.42 reflected prevalent fractures with 91.7 % sensitivity and(More)
To determine osteocalcin (OC) and adipokines in type 1 diabetes (T1D) and healthy controls, and to explore possible associations between glucose and bone metabolism, body composition and adipokines. Serum levels of total OC, undercarboxylated (UC-OC), leptin, adiponectin, and other parameters of glucose and bone metabolism were measured in 128 patients with(More)
PURPOSE The aim of this study was to investigate the potential dose reduction in the uterus as a result of lead apron protection during thoracic CT scans. Moreover, the distribution of the radiation dose in the uterus was determined in order to obtain information about the ratio of internally and externally scattered radiation. MATERIALS AND METHODS The(More)
The purpose of this study was to determine the influence of iodinated contrast agents on the formation of DNA double-strand breaks in vitro in lymphocytes and to verify these results in patients undergoing diagnostic computed tomography examinations. Blood samples were irradiated in vitro in the presence of iodinated X-ray contrast agent. Controls were(More)
