[Poor sleep quality and inadequate sleep duration related to obesity in two Roma subgroups in Transylvania].

Short sleep duration and poor sleep quality may be associated with weight gain; this association has not yet been studied in Roma (Gipsy) population. Our aim was to study sleep patterns in two adult Roma subgroups (the wealthy Gabor and the poor Lovari Roma), compared to the majority of Hungarian population, in relation to obesity, knowing that Roma population has specific socio-cultural characteristics, with a rapidly changing lifestyle. A population-based cross-sectional survey was conducted in a rural region in Transylvania, where the above groups are cohabiting.

Epigenetic Modifications Linked to T2D, the Heritability Gap, and Potential Therapeutic Targets.

With the pandemic of type 2 diabetes (T2D), there is an ever-increasing need to fully understand the underlying mechanisms of the disease. Type 2 diabetes shows a high heritability risk (25-80%); however, genes account only for 10% of this risk. From all the risk factors for diabetes, epigenetic mechanisms have the highest statistical scoring in explaining the disease.

Genetic Approaches to the Study of Gene Variants and Their Impact on the Pathophysiology of Type 2 Diabetes.

Diabetes mellitus is an incurable progressive disease, characterized by elevated blood glucose levels, which lead to the development of micro- and macrovascular complications. Although the etiopathology of the disease remains unclear, it seems to be multifactorial, with an important interaction between genetics and environmental causes. Currently, the genetics of type 2 diabetes (T2D) is poorly understood.

FDG PET is superior to CT in the prediction of viable tumour in post-chemotherapy seminoma residuals.

Aim: In advanced seminoma the management of residuals after completion of chemotherapy is controversial. Some centres routinely perform surgery for lesions > or =3 cm diameter, others recommend surgery solely if the residual fail to shrink or show even growth. This study prospectively investigates whether FDG PET can improve the prediction of viable tumour in post-chemotherapy seminoma residuals.

Imaging of advanced neuroendocrine tumors with (18)F-FDOPA PET.

Unlabelled: Nuclear medicine plays an important role in the imaging of neuroendocrine tumors (NETs). Somatostatin receptor scintigraphy (SRS) with (111)In-labeled somatostatin receptor analogs is a standard procedure for the detection and staging of NET. Based on the ability of NETs to store biogenic amines, this study evaluated whether 6-(18)F-fluoro-L-DOPA ((18)F-FDOPA) is a suitable PET tracer for NETs.

Isotopic renal function studies in severe hypothyroidism and after thyroid hormone replacement therapy.

Aim: To investigate the possible changes in the renal tubular function in severe short-term hypothyroidism using (99m)Tc-MAG(3) renography.

Methods: 27 consecutive thyroidectomized patients (7 males and 20 females) aged 19-79 (mean 53) years were included in the present study. (99m)Tc-MAG(3) renography was performed in all patients before and after thyroid hormone replacement therapy.

Brain tumour imaging with PET: a comparison between [18F]fluorodopa and [11C]methionine.

Imaging of amino acid transport in brain tumours is more sensitive than fluorine-18 2-fluoro-deoxyglucose positron emission tomography (PET). The most frequently used tracer in this field is carbon-11 methionine (MET), which is unavailable for PET centres without a cyclotron because of its short half-life. The purpose of this study was to evaluate the performance of 3,4-dihydroxy-6-[(18)F]fluoro-phenylalanine (FDOPA) in this setting, in comparison with MET.
